CROSS-REFERENCE TO RELATED APPLICATION

The application is based on the Chinese patent application No. 202411657520X, filed on Nov. 19, 2024, and claims the priority of the patent application, the whole contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the technical field of heat pumps, and in particular to a heat pump water module and a heat pump device.

BACKGROUND ART

The heat pump device includes a heat pump host, a water module, and a terminal device, etc. The heat pump host heats or cools water delivered by the water module, and the water module then delivers the heated or cooled water to the terminal device to meet the user's needs for domestic hot water, heating, etc. A cold water pipeline of the heat pump water module is usually equipped with a water pump to provide power for the water in the terminal device to flow to the heat pump host.

However, the water pump of the heat pump water module in the prior art is not easy to disassemble and assemble, therefore it is not easy to repair and maintain. In addition, in the prior art, the installation scenario of the heat pump water module is mostly wall-mounted, and it is generally set to lower side outlet, which cannot meet the needs of various installation scenarios. When users have multiple usage requirements, multiple heat pump water modules are usually installed to supply hot water or cold water to multiple terminal devices respectively, which occupies a relatively large space.

SUMMARY

The first object of the present disclosure is to provide a heat pump water module, to solve a technical problem that the water pump of the heat pump water module in the prior art is not easy to disassemble and assemble.

The heat pump water module provided in the present disclosure includes a box and at least one waterway system arranged in the box, and the waterway system includes a cold water pipeline and a hot water pipeline; the cold water pipeline includes a cold water inlet pipeline, a water pump assembly and a cold water outlet pipeline which are detachably fixedly connected, and there is no pipeline shielding in front of the connection parts at both ends of the water pump assembly.

The heat pump water module provided in the present disclosure can produce the following beneficial effects.

After the heat pump water module provided in the present disclosure is connected to the heat pump host and the terminal device, the cold water pipeline of the heat pump water module can transport water in the terminal device to the heat pump host, and after the heat pump host heats or cools the water, the hot water pipeline of the heat pump water module transports hot water or cold water to the terminal device.

Herein, since there is no pipeline shielding in front of the connection parts at both ends of the water pump assembly in the cold water pipeline, after removing or opening the components in front of it such as the front panel, the two ends of the water pump assembly can be easily disassembled and assembled, so that the water pump assembly can be removed from between the cold water inlet pipeline and the cold water outlet pipeline, or the water pump assembly can be installed between the cold water inlet pipeline and the cold water outlet pipeline, which can greatly improve the efficiency of inspection and maintenance.

Further, the water pump assembly is fixedly connected to the cold water inlet pipeline by a first nut, and there is no pipeline shielding in front of the first nut; and/or, the water pump assembly is fixedly connected to the cold water outlet pipeline by a second nut, and there is no pipeline shielding in front of the second nut. Under this technical solution, the water pump assembly can be disassembled and assembled by screwing the nut, which is very convenient.

Further, the cold water inlet pipeline is fixedly provided with a communicating connector, and the water outlet end of the communicating connector is connected to the water inlet end of the water pump assembly by the first nut. By providing a communicating connector at the water outlet end of the cold water inlet pipeline, the water outlet end of the cold water inlet pipeline can be easily installed and removed while ensuring that the cold water inlet pipeline and the water pump assembly are easy to install and remove, and the water outlet end of the cold water inlet pipeline can be avoided from being modified, which is very convenient.

Further, the first nut includes a first body and a first limiting ring fixed to the first body, the first limiting ring has a first limiting surface; one of the communicating connector and the water pump assembly is provided with a first limiting protrusion, the first limiting protrusion is annular, the outer diameter of the first limiting protrusion is smaller than the inner diameter of the first body, and larger than the minimum inner diameter of the first limiting ring; the other of the communicating connector and the water pump assembly is provided with a first thread, the inner thread of the first nut is threadedly connected to the first thread, and the first limiting surface is tightly abutted against the first limiting protrusion.

Under this technical solution, when the water inlet end of the water pump assembly needs to be disassembled, it is only necessary to unscrew the first nut from the first thread, which is very fast and convenient. Moreover, under the blocking effect of the first limiting protrusion, the first nut will not fall off.

Further, the communicating connector includes a two-way connector, the water outlet end of the two-way connector is connected to the water pump assembly through the first nut, and the water inlet end of the two-way connector is connected to the cold water inlet pipeline; and/or, the communicating connector includes a three-way connector, the first end of the three-way connector is connected to the water pump assembly through the first nut, the second end is connected to the cold water inlet pipeline, and the third end is configured to be connected to other cold water pipelines.

Further, the water pump assembly includes a water pump and a check valve, the water pump is connected to the communicating connector, the check valve is connected to the cold water outlet pipeline, and one of the water inlet end of the check valve and the water outlet end of the water pump is provided with an internal thread, and the other is provided with an external thread, and the two are fixedly connected by the external thread and the internal thread.

Under this technical solution, when the water pump needs to be disassembled, the water pump assembly can be disassembled from the cold water pipeline, and then the water pump and the check valve can be disassembled.

Further, the second nut includes a second body and a second limiting ring fixed to the second body, the second limiting ring has a second limiting surface; one of the cold water outlet pipe and the check valve is provided with a second limiting protrusion, the second limiting protrusion is annular, the outer diameter of the second limiting protrusion is smaller than the inner diameter of the second body, and larger than the minimum inner diameter of the second limiting ring; the other of the cold water outlet pipe and the check valve is provided with a second thread, the inner thread of the second nut is threadedly connected to the second thread, and the second limiting surface is tightly abutted with the second limiting protrusion.

Under this technical solution, when the water pump needs to be disassembled, the second nut can be unscrewed from the second thread, that is, the water pump assembly can be disassembled from the cold water pipeline, and then the water pump and the check valve can be disassembled; and under the blocking effect of the second limiting protrusion, the second nut will not fall off.

Further, the check valve is fixedly connected to the rear wall plate of the box. By such an arrangement, the position of the check valve is fixed and restricted, and at the same time, the water pump and the cold water outlet pipeline at both ends of the check valve are also better supported and restricted, therefore it is beneficial to improve the stability of the entire cold water pipeline.

Further, there are at least two waterway systems, namely the first waterway system and the second waterway system; the water pump assembly of the first waterway system and the water pump assembly of the second waterway system are arranged adjacent to each other in an up-down direction, and are located in a lower part or a middle part of the box.

Under this technical solution, since the weight of the water pump assembly is relatively heavy, such an arrangement can lower the center of gravity of the entire water module, making the entire water module more stable.

Further, the hot water pipeline of the first waterway system is a first hot water pipeline, the first hot water pipeline includes a first hot water inlet pipeline and a first hot water outlet pipeline, the first hot water outlet pipeline includes a first hot water outlet pipe section, a three-way valve and a second hot water outlet pipe section which are fixedly connected in sequence; the hot water pipeline of the second waterway system is a second hot water pipeline, the second hot water pipeline includes a second hot water inlet pipe section and a second hot water outlet pipe section; the water inlet end and a water outlet end of the three-way valve are respectively connected to the first hot water outlet pipe section and the second hot water outlet pipe section, and the other water outlet end of the three-way valve is communicated with the second hot water outlet pipe section.

Under this technical solution, when one set of terminal devices such as a domestic water tank reaches the temperature, and the other set of terminal devices such as a heating terminal has a large demand but cannot be met, by adjusting the three-way valve, the first waterway system and the second waterway system can jointly provide a heat source or a cold source to the heating terminal to quickly meet the user's heating or cooling needs. Moreover, the arrangement of the three-way valve also facilitates the disassembly and assembly of the second waterway system. When the installation scenario changes, the disassembly and assembly of the second waterway system can be directly completed through the three-way valve. In addition, when three or more waterway systems need to be installed, a multi-way valve body or multiple three-way valves can be added to the first waterway system or the second waterway system, to connect the hot water pipelines to each other so as to complement each other.

Further, the three-way valve includes a valve body and an actuator, the valve body has a water inlet end and two water outlet ends, the actuator is arranged on the top of the valve body, and there is a gap for disassembly and assembly between the actuator and the top plate of the box, and the value range of the gap for disassembly and assembly is 10 mm to 30 mm.

DETAILED DESCRIPTION OF EMBODIMENTS

In order to make the above-mentioned purposes, features, and advantages of the present disclosure more obvious and easier to understand, the specific embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present disclosure and are not used to limit the present disclosure.

The present embodiment provides a heat pump water module and a heat pump device. The water pump assembly of the heat pump water module is very easy to disassemble and assemble, which can greatly improve the efficiency of maintenance and repair; the heat pump device includes the above-mentioned heat pump water module, and further includes a heat pump host and a terminal device, and the heat pump water module is connected between the heat pump host and the terminal device.

The heat pump water module provided in the present embodiment is described in detail below.

As shown in FIGS. 1 and 2, the heat pump water module provided in the present embodiment includes a box 100 and at least one waterway system arranged in the box 100, and the waterway system includes a cold water pipeline and a hot water pipeline; the cold water pipeline includes a cold water inlet pipeline, a water pump assembly and a cold water outlet pipeline which are detachably fixedly connected, and there is no pipeline shielding in front of the connection parts at both ends of the water pump assembly.

In the present embodiment, there are two waterway systems, namely the first waterway system and the second waterway system. The two waterway systems can be connected to a terminal device respectively. The terminal device connected to the first waterway system is the first terminal device, and the terminal device connected to the second waterway system is the second terminal device. The first terminal device and the second terminal device are different. In practical applications, the first terminal device is preferably a domestic water tank, and the second terminal device is preferably at least one of the following: air conditioning, floor heating and radiator group. The first terminal device and the second terminal device can be specifically set according to actual conditions, which will not be repeated in the present embodiment. It should be noted that in other embodiments of the present application, it is not limited that there are two waterway systems, but can also be one, or three or four, etc., which can be set according to specific needs.

The heat pump water module provided in the present embodiment has no pipeline shielding in front of the connection parts at both ends of the water pump assembly in the cold water pipeline. Therefore, after removing or opening the components in front of it, such as the front panel of the box 100, the two ends of the water pump assembly can be easily disassembled and assembled, so that the water pump assembly can be removed from between the cold water inlet pipeline and the cold water outlet pipeline, as shown in FIG. 5, or the water pump assembly can be installed between the cold water inlet pipeline and the cold water outlet pipeline, which can greatly improve the efficiency of inspection and maintenance.

In the present embodiment, the water outlet side of the hot water pipeline and the cold water inlet pipeline both pass through the right side plate 140 of the box 100, and are both configured to be connected to the terminal device; the inlet side of the hot water pipeline and the cold water outlet pipeline both pass through the left side plate 130 of the box 100, and are both configured to be connected to the heat pump host. Of course, in other embodiments of the present application, the outlet side of the hot water pipeline and the cold water inlet pipeline can also both pass through the left side plate 130 of the box 100, and the inlet side of the hot water pipeline and the cold water outlet pipeline can both pass through the right side plate 140 of the box 100. In this way, the two sides of the box 100 can be connected to the heat pump host and the terminal device respectively, which is very convenient for after-sales installation and pipe connection. The cold water pipeline of the heat pump water module can transport the water in the terminal device to the heat pump host. After the heat pump host heats or cools the water, the hot water pipeline of the heat pump water module transports the hot water or cold water to the terminal device. Moreover, in this way, it can be installed as a wall-mounted type or a floor-standing type, and the applicable scenarios are greatly increased.

Specifically, in the present embodiment, as shown in FIG. 1, the water pump assembly is fixedly connected to the cold water inlet pipeline by the first nut 230, and there is no pipeline shielding in front of the first nut 230; the water pump assembly is fixedly connected to the cold water outlet pipeline by the second nut 260, and there is no pipeline shielding in front of the second nut 260. In this setting form, the water pump assembly can be disassembled and assembled by screwing the nut, which is very convenient.

It should be noted here that in other embodiments of the present application, for two ends of the water pump assembly, only the water inlet end or only the water outlet end can be connected to the corresponding pipeline through a nut, and the other can be connected through other detachable fixed connection methods, for example: only the water inlet end of the water pump assembly is connected to the cold water inlet pipeline through a nut, and the water outlet end of the water pump assembly is fixedly connected to the cold water outlet pipeline through a flange or other structure. Of course, in other embodiments of the present application, both ends of the water pump assembly can also be detachably fixedly connected to the corresponding pipeline through a flange. That is, as long as the water pump is detachable and easy to disassemble, the present application does not impose specific restrictions on the connection structure at its two ends.

More specifically, in the present embodiment, as shown in FIG. 1, the cold water inlet pipeline is fixedly provided with a communicating connector, and the water outlet end of the communicating connector is connected to the water inlet end of the water pump assembly through a first nut 230. Herein, the communicating connector includes a two-way connector and a three-way connector, which can be selected according to specific needs. As shown in FIG. 1, in the first waterway system, the water inlet end of the water pump assembly is connected with a three-way connector, the first end of the three-way connector is connected to the water inlet end of the water pump assembly through the first nut 230, the second end is connected to the cold water inlet pipeline, and the third end is configured to be connected to other cold water pipelines (such as the cold water inlet pipeline of the second waterway system); while in the second waterway system, the water inlet end of the water pump assembly is connected with a two-way connector, the water outlet end of the two-way connector is connected to the water inlet end of the water pump assembly through the first nut 230, and the water inlet end of the two-way connector is connected to the water outlet end of the cold water inlet pipeline. By setting a communicating connector at the water outlet end of the cold water inlet pipeline, while ensuring that the cold water inlet pipeline and the water pump assembly are easy to assemble and disassemble, it is also possible to avoid modifying the water outlet end of the cold water inlet pipeline, which is very convenient.

In the present embodiment, as shown in FIGS. 6 and 9, the first nut 230 includes a first body 231 and a first limiting ring 232 fixed to the first body 231, and the first limiting ring 232 has a first limiting surface 233; the communicating connector is provided with a first limiting protrusion 221, the first limiting protrusion 221 is annular, the outer diameter of the first limiting protrusion 221 is smaller than the inner diameter of the first body 231, and larger than the minimum inner diameter of the first limiting ring 232; the water pump assembly is provided with a first thread 241, the inner thread of the first nut 230 is threadedly connected to the first thread 241, and the first limiting surface 233 is tightly abutted with the first limiting protrusion 221. In this setting form, when the water inlet end of the water pump assembly needs to be disassembled, it is only necessary to unscrew the first nut 230 from the first thread 241, which is very fast and convenient. Moreover, under the blocking effect of the first limiting protrusion 221, the first nut 230 will not fall off.

It should be noted here that in other embodiments of the present application, the setting positions of the first limiting protrusion 221 and the first thread 241 can also be swapped. At that time, the first nut 230 is sleeved outside the water inlet end of the water pump assembly, that is, the water inlet end of the water pump assembly is provided with the first limiting protrusion 221, and the water outlet end of the communicating connector is provided with the first thread 241. The first nut 230 is sleeved outside the water inlet end of the water pump assembly, and the water inlet end of the water pump assembly and the water outlet end of the communicating connector are fixedly connected, which is also very convenient for disassembly and assembly.

It should also be noted that the first limiting protrusion 221 can be directly set at the water outlet end of the communicating connector, or a first flexible joint can be used, which is a hollow T-shaped joint, and the first flexible joint is fixedly set inside or outside the water outlet end of the communicating connector, and the radial protrusion of the first flexible joint forms the first limiting protrusion 221.

In the present embodiment, as shown in FIG. 6, the water pump assembly includes a water pump and a check valve, the water pump is used to provide power for the water flow, the check valve can also be called a one-way valve, used to prevent water backflow, the water pump is connected to the communicating connector, the check valve is connected to the cold water outlet pipeline, and the water inlet end of the check valve is provided with an internal thread 251, and the water outlet end of the water pump is provided with an external thread 242, and the two are fixedly connected by the external thread 242 and the internal thread 251. Of course, in other embodiments of the present application, it can be also possible that the water outlet end of the water pump is provided with an internal thread 251, and the water inlet end of the check valve is provided with an external thread 242, at that time, the water outlet end of the water pump and the water inlet end of the check valve can still be fixedly connected by the external thread 242 and the internal thread 251. In this setting form, when the water pump needs to be disassembled, the water pump assembly can be disassembled from the cold water pipeline, and then the water pump and the check valve can be disassembled. Of course, in other embodiments of the present application, the water inlet end of the check valve and the water outlet end of the water pump can also be directly connected through the second nut 260. At that time, when the water pump needs to be disassembled, only the water pump needs to be disassembled.

As shown in FIGS. 6 and 9, the second nut 260 includes a second body 261 and a second limiting ring 262 fixed to the second body 261, and the second limiting ring 262 has a second limiting surface 263; the cold water outlet pipeline is provided with a second limiting protrusion 2751, the second limiting protrusion 2751 is annular, and the outer diameter of the second limiting protrusion 2751 is smaller than the inner diameter of the second body 261, and larger than the minimum inner diameter of the second limiting ring 262; the check valve is provided with a second thread 252, the inner thread of the second nut 260 is threadedly connected to the second thread 252, and the second limiting surface 263 is tightly abutted against the second limiting protrusion 2751. In this setting form, when the water pump needs to be disassembled, the second nut 260 can be unscrewed from the second thread 252, that is, the water pump assembly can be disassembled from the cold water pipeline, and then the water pump and the check valve can be disassembled; furthermore, under the blocking effect of the second limiting protrusion 2751, the second nut 260 will not fall off.

In other embodiments of the present application, the setting positions of the second limiting protrusion 2751 and the second thread 252 can also be swapped. At that time, the second nut 260 is sleeved outside the water outlet end of the check valve, that is, the water outlet end of the check valve is provided with a second limiting protrusion 2751, and the water inlet end of the cold water outlet pipeline is provided with a second thread 252. The second nut 260 is sleeved outside the water outlet end of the check valve, and the water inlet end of the cold water outlet pipeline and the water outlet end of the check valve are fixedly connected, which is also very convenient for disassembly and assembly.

In the present embodiment, as shown in FIG. 1, the water pump assembly of the first waterway system and the water pump assembly of the second waterway system are arranged adjacent to each other at the top and bottom, and are located at the bottom or middle of the box 100, close to the bottom plate 160. Since the water pump assembly is heavy, such an arrangement can lower the center of gravity of the entire water module, making the entire water module more stable.

Specifically, in the present embodiment, as shown in FIG. 1, and in combination with FIGS. 3 and 6, in the present embodiment, the cold water inlet pipeline of the first cold water pipeline 200 is the first cold water inlet pipeline 210, the water pump assembly of the first cold water pipeline 200 is the first water pump assembly, and the cold water outlet pipeline of the first cold water pipeline 200 is the first cold water outlet pipeline 270; the cold water inlet pipeline of the second cold water pipeline 400 is the second cold water inlet pipeline 410, the water pump assembly of the second cold water pipeline 400 is the second water pump assembly, and the cold water outlet pipeline of the second cold water pipeline 400 is the second cold water outlet pipeline 470.

Herein, the first cold water inlet pipeline 210 and the second cold water inlet pipeline 410 have basically the same direction, and each cold water inlet pipeline includes a first transverse pipe section 211, a first bending portion 212, a first longitudinal pipe section 213, a second bending portion 214 and a second transverse pipe section 215 from its water inlet end to its water outlet end, and the first longitudinal pipe section 213 extends from the first bending portion 212 to the second bending portion 214 in a direction away from the front panel.

The first cold water outlet pipe 270 and the second cold water outlet pipe 470 have the same direction, and each cold water outlet pipe includes a third transverse pipe section 271, a third bending portion 272, a second longitudinal pipe section 273, a fourth bending portion 274 and a fourth transverse pipe section 275 from its water outlet end to its water inlet end, and the second longitudinal pipe section 273 extends from the third bending portion 272 to the fourth bending portion 274 in a direction away from the front panel.

The first water pump assembly is transversely arranged and connected between the second transverse pipe section and the fourth transverse pipe section of the first cold water pipeline 200; and the second water pump assembly is transversely arranged and connected between the second transverse pipe section and the fourth transverse pipe section of the second cold water pipeline 400.

In the above setting form, from a top view, the first cold water pipeline 200 and the second cold water pipeline 400 are both roughly in the shape of a Chinese character “” or “Ω”. The first cold water pipeline 200 and the second cold water pipeline 400 occupy a relatively small space in the height direction, therefore the height of the box 100 can be reduced, and the center of gravity of the entire water module can also be reduced; the first water pump assembly and the second water pump assembly are respectively arranged between the corresponding first longitudinal pipe section 213 and the second longitudinal pipe section 273, and are arranged forward, which is very convenient for disassembly, assembly and maintenance; the space between the first longitudinal pipe section 213 and the right side plate 140 can be used to arrange other pipes or components, such as hot water pipes; the space between the second longitudinal pipe section 273 and the left side plate 130 can also be used to arrange other pipes or components, such as electric heaters. With such an arrangement, the entire box 100 is very stable, the structure inside is also very compact, and the space utilization rate is high, which can greatly reduce the volume and occupied space of the entire heat pump water module, thereby expanding the application scenarios, and can also increase the cabinet loading quantity and reduce transportation costs.

In the present embodiment, as shown in FIG. 1, the check valve of the first waterway system is a first check valve 250, which is used to prevent the water of the first cold water pipeline 200 from flowing back; the check valve of the second waterway system is a second check valve 450, which is used to prevent the water of the second cold water pipeline 400 from flowing back, and both are fixedly connected to the rear wall plate 120 of the box 100. With such an arrangement, the position of the check valve is fixed and restricted, and at the same time, the water pump and the cold water outlet pipeline at both ends of the check valve are also better supported and restricted, therefore it is beneficial to improve the stability of the entire cold water pipeline.

In the present embodiment, as shown in FIG. 1, a filter 420 is provided at the water inlet end of the second cold water pipeline 400, which can filter impurities of the second terminal device, thereby protecting the water supply pipeline, water pump and heat pump host. Moreover, the filter 420 is built into the box 100, and there is no need to install the filter 420 between the water module and the second terminal device during after-sales installation, which can greatly improve the installation efficiency and improve the user experience.

Continuing as shown in FIG. 1, in the present embodiment, a first connecting pipeline 600 is further connected between the second cold water inlet pipeline 410 and the first cold water inlet pipeline 210, and one end of the first connecting pipeline 600 connected to the second cold water inlet pipeline 410 is located between the filter 420 and the second water pump assembly.

Specifically, in the present embodiment, the first connecting pipeline 600 includes a fixed inclined longitudinal straight pipe 610 and a connecting curved pipe 620; the first cold water inlet pipeline 210 is provided with a T-shaped three-way connector 220, and the two straight ends of the T-shaped three-way connector 220 are respectively connected to the first cold water inlet pipe 210 and the first water pump assembly, and the third end of the T-shaped three-way connector 220 is connected to the inclined longitudinal straight pipe 610; the second cold water inlet pipeline 410 is provided with a filter 420 and a first Y-shaped three-way connector 430, and the symmetrical two ends of the first Y-shaped three-way connector 430 are respectively connected to the water inlet end of the first bending portion of the second cold water inlet pipeline 410 and the connecting curved pipe 620, and the third end of the first Y-shaped three-way connector 430 is connected to the water outlet end of the filter 420, and the water inlet end of the filter 420 is connected to the water outlet end of the first transverse pipe section of the second cold water inlet pipeline 410. By setting a T-shaped three-way connector 220 and a first Y-shaped three-way connector 430, and connecting the first cold water inlet pipeline 210 and the second cold water inlet pipeline 410 through the first connecting pipeline 600, the first cold water pipeline 200 and the second cold water pipeline 400 can replenish water with each other, so that the water volume and water pressure and so on in the two cold water pipelines are more balanced.

Continuing as shown in FIG. 1, in the present embodiment, the first connecting pipeline 600 is provided with a pressure gauge 820, which is used to detect the water pressure in the pipeline. Since the first cold water pipeline 200 and the second cold water pipeline 400 is connected through the first connecting pipeline 600, in other embodiments of the present application, the pressure gauge 820 can also be set in the first cold water pipeline 200 or the second cold water pipeline 400.

In the present embodiment, the water inlet end of the first cold water pipeline 200, the water outlet end of the first hot water pipeline 300, the water inlet end of the second cold water pipeline 400, and the water outlet end of the second hot water pipeline 500 all pass through the right side plate 140 of the box 100, and are arranged in sequence from bottom to top; the water outlet end of the first cold water pipeline 200, the water inlet end of the first hot water pipeline 300, the water outlet end of the second cold water pipeline 400, and the water inlet end of the second hot water pipeline 500 all pass through the left side plate 130 of the box 100, and are arranged in sequence from bottom to top. Of course, in other embodiments of the present application, the water inlet end and water outlet of each pipeline can also be swapped, that is, the water inlet of the first cold water pipeline 200, the water outlet of the first hot water pipeline 300, the water inlet of the second cold water pipeline 400, and the water outlet of the second hot water pipeline 500 all pass through the left side plate 130, and the water outlet of the first cold water pipeline 200, the water inlet of the first hot water pipeline 300, the water outlet of the second cold water pipeline 400, and the water inlet of the second hot water pipeline 500 all pass through the right side plate 140. By such an arrangement, the water inlet of the cold water pipeline of each waterway system is adjacent to the water outlet of the hot water pipeline, which is convenient for connection with the terminal device; the water outlet end of the cold water pipeline of each waterway system is adjacent to the water inlet end of the hot water pipeline, which is convenient for connection with the heat pump host.

In the heat pump water module provided in the present embodiment, each hot water pipeline is provided with an electric heater for rapid auxiliary heating to better meet customer needs. Moreover, in the heat pump water module provided in the present embodiment, the electric heater is also very easy to disassemble and assemble, which is described in detail below.

As shown in FIG. 2, in the heat pump water module provided in the present embodiment, the hot water pipeline includes a hot water inlet pipeline, an electric heater and a hot water outlet pipeline which are detachably fixedly connected, and there is no pipeline shielding in front of the connection parts at both ends of the electric heater. In the heat pump water module provided in the present embodiment, the setting of the electric heater plays an auxiliary heating role, so as to quickly heat the water to the required temperature to better meet customer needs. Moreover, after the front panel and other components of the box 100 are removed or opened, the two ends of the electric heater can be easily disassembled and assembled, so that the electric heater can be removed from between the hot water inlet pipeline and the hot water outlet pipeline, or the electric heater can be installed between the hot water inlet pipeline and the hot water outlet pipeline, which can greatly improve the efficiency of inspection and maintenance.

Specifically, in the present embodiment, as shown in FIGS. 4, 7, 8, 10, and 11, the water inlet end of the electric heater is butted against the water outlet end of the hot water inlet pipeline and fixedly connected by a first clamp 340; the inner peripheral wall of the first clamp 340 is provided with a first annular groove 341, the outer peripheral wall of the water inlet end of the electric heater is provided with a first annular protrusion 321, and the outer peripheral wall of the water outlet end of the hot water inlet pipeline is provided with a second annular protrusion 314, and the first annular protrusion 321 is butted against the second annular protrusion 314, and both are clamped in the first annular groove 341.

The water outlet end of the electric heater is butted against the water inlet end of the hot water outlet pipe and fixedly connected by the second clamp 350; the inner peripheral wall of the second clamp 350 is provided with a second annular groove 351, the outer peripheral wall of the water outlet end of the electric heater is provided with a third annular protrusion 322, and the outer peripheral wall of the water inlet end of the hot water outlet pipe is provided with a fourth annular protrusion 3311, and the third annular protrusion 322 is butted against the fourth annular protrusion 3311, and both are clamped in the second annular groove 351.

The water inlet end of the electric heater and the water outlet end of the hot water inlet pipeline are fixedly connected by the first clamp 340, and the water outlet end of the electric heater and the water inlet end of the hot water outlet pipeline are fixedly connected by the second clamp 350, so that the parts are easy to obtain and very convenient for disassembly and assembly.

More specifically, in the present embodiment, the first clamp 340 and the second clamp 350 can be knob-type clamps, and there is no pipeline shielding in front of the knob, which is convenient for disassembly and assembly.

It should be noted here that in other embodiments of the present application, it is also possible that only the water inlet end of the electric heater and the water outlet end of the hot water inlet pipeline are connected by a clamp, while the water outlet end of the electric heater and the water inlet end of the hot water outlet pipeline are fixedly connected by a flange or other structure; or only the water outlet end of the electric heater and the water inlet end of the hot water outlet pipeline are connected by a clamp, while the water inlet end of the electric heater and the water outlet end of the hot water inlet pipeline are connected by a flange or other structure. Of course, in other embodiments of the present application, both ends of the electric heater may also be detachably fixedly connected to the corresponding pipeline by a flange. That is, as long as the electric heater is detachable and easy to detach, the present application may not impose specific restrictions on the connection structure of its two ends.

It should also be noted that the second annular protrusion 314 can be directly set at the water outlet of the hot water inlet pipeline, or the second flexible joint 3142 can be used, as shown in FIG. 10, which is a hollow T-shaped joint. The second flexible joint 3142 is placed outside or inside the water outlet of the hot water inlet pipe, and the radial protrusion of the second flexible joint 3142 forms the second annular protrusion 314. Similarly, the fourth annular protrusion 3311 can be directly set at the water inlet end of the hot water outlet pipeline, or the third flexible joint 3313 can be used, which is a hollow T-shaped joint. The third flexible joint 3313 is placed outside or inside the water inlet of the hot water outlet pipeline, and the radial protrusion of the third flexible joint 3313 forms the fourth annular protrusion 3311.

More specifically, in the present embodiment, as shown in FIG. 10, the end surface of the first annular protrusion 321 away from the second annular protrusion 314 is a first annular slope 3211, and from the top to the bottom of the first annular protrusion 321, the first annular slope 3211 is inclined in a direction away from the second annular protrusion 314; the end surface of the second annular protrusion 314 away from the first annular protrusion 321 is a second annular slope 3141, and from the top to the bottom of the second annular protrusion 314, the second annular slope 3141 is inclined in a direction away from the first annular protrusion 321. In other embodiments of the present application, only one of the first annular slope 3211 and the second annular slope 3141 may be provided.

Continuing as shown in FIG. 10, the end surface of the third annular protrusion 322 away from the fourth annular protrusion 3311 is a third annular slope 3221, and from the top to the bottom of the third annular protrusion 322, the third annular slope 3221 is inclined in a direction away from the fourth annular protrusion 3311; the end surface of the fourth annular protrusion 3311 away from the third annular protrusion 322 is the fourth annular slope 3312, and from the top to the bottom of the fourth annular protrusion 3311, the fourth annular slope 3312 is inclined in a direction away from the third annular protrusion 322. In other embodiments of the present application, only one of the third annular slope 3221 and the fourth annular slope 3312 may be provided.

The settings of the above annular slopes all play a guiding role on the clamp, so that the clamping groove and the protrusion can be clamped faster and more accurately. Moreover, the setting of the annular slope makes the degree of tightness of the clamp adjustable, so as to ensure that the electric heater is tightly fixed to the corresponding pipeline, ensure the reliability of the connection between the two, and also ensure the sealing of the connection between the two.

In order to further ensure the sealing of the connection, as shown in FIG. 10, the end surfaces opposite to the first annular protrusion 321 and the second annular protrusion 314 are provided with sealing rings (not shown in the figure), and the end surfaces opposite to the third annular protrusion 322 and the fourth annular protrusion 3311 are also provided with sealing rings (not shown in the figure). In order to limit the sealing rings, at least one of the two opposite end surfaces is also provided with an annular groove.

In the present embodiment, as shown in FIG. 2, the hot water pipeline of the first waterway system is the first hot water pipeline 300, the first hot water pipeline 300 includes the first hot water inlet pipeline 310 and the first hot water outlet pipeline 330, and the first hot water outlet pipeline 330 includes the first hot water outlet pipe section 331, the three-way valve 332 and the second hot water outlet pipe section 333 which are fixedly connected in sequence; the hot water pipeline of the second waterway system is the second hot water pipeline 500, and the second hot water pipeline 500 includes the second hot water inlet pipeline 510 and the second hot water outlet pipeline 530; the water inlet end and the water outlet end of the three-way valve 332 are respectively connected to the first hot water outlet pipe section 331 and the second hot water outlet pipe section 333, and the other water outlet end of the three-way valve 332 is communicated with the second hot water outlet pipe section 530.

In the above setting form, when one of the terminal devices, such as the domestic water tank, reaches the temperature, and the other terminal device, such as the heating terminal, has a large demand but cannot meet it, by adjusting the three-way valve 332, the first waterway system and the second waterway system can jointly provide a heat source or a cold source to the heating terminal to quickly meet the user's heating or cooling needs. Moreover, the three-way valve 332 is also convenient for the disassembly and assembly of the second waterway system. When the installation scene changes, the disassembly and assembly of the second waterway system can be directly completed through the three-way valve 332. In addition, when three or more waterway systems need to be installed, a multi-way valve body or multiple three-way valves 332 can be added to the first waterway system or the second waterway system, to connect the hot water pipelines to each other so as to complement each other.

As shown in FIG. 2, the three-way valve 332 includes a valve body 3321 and an actuator 3322. The valve body 3321 has a water inlet end and two water outlet ends. The actuator 3322 is arranged at the top of the valve body 3321, and there is a gap for disassembly and assembly between the actuator 3322 and the top plate 150 of the box 100. The value range of the gap for disassembly and assembly is 10 mm to 30 mm. The height of the connecting part between the actuator 3322 and the valve body 3321 is not too high, and the value range can meet the disassembly and assembly requirements of the actuator 3322. Further, the gap for disassembly and assembly can be 20 mm to 30 mm, thereby providing a larger space for the actuator 3322 to be disassembled and assembled, so as to improve its disassembly and assembly convenience.

In the present embodiment, in combination with FIGS. 2 and 8, the hot water inlet pipeline of the first hot water pipeline 300 is the first hot water inlet pipeline 310, and the electric heater of the first hot water pipeline 300 is the first electric heater 320. The first electric heater 320 is placed vertically, and the water inlet end of the first electric heater 320 is located at its bottom end; the first hot water inlet pipeline 310 includes a first straight pipe 311, a first curved pipe 312 and a U-shaped pipe 313 which are fixedly connected in sequence, and the opening of the U-shaped pipe 313 faces upward and is arranged along the front-to-back direction; the first electric heater 320 is located behind the first straight pipe 311, and the water inlet end of the first electric heater 320 is connected to the water outlet end of the U-shaped pipe 313 and is lower than the first straight pipe 311. In this setting form, the first water pump 240 and the second water pump 440 are arranged transversely in the lower part or middle part of the box 100, and the first electric heater 320 is located behind the third transverse pipe section of the first cold water pipeline 200 and the third transverse pipe section of the second cold water pipeline 400, which not only effectively utilizes the space behind the two third transverse pipe sections, improves the compactness of the overall structure, but also reduces the height of the box 100 compared with the solution in which each electric heater is arranged transversely.

Specifically, in the present embodiment, the hot water inlet pipeline of the second hot water pipeline 500 is the second hot water inlet pipeline 510, the electric heater of the second hot water pipeline 500 is the second electric heater 520, and the hot water outlet pipeline of the second hot water pipeline 500 is the second hot water outlet pipeline 530; the second hot water inlet pipeline 510 is arranged transversely, and the second electric heater 520 is arranged transversely between the water outlet end of the second hot water inlet pipeline 510 and the water inlet end of the second hot water outlet pipeline 530. The second hot water pipeline 500 is basically arranged transversely, therefore it occupies a small space and can effectively control the height of the box 100.

In the present embodiment, as shown in FIG. 3, the second connecting pipeline 700 is L-shaped, including a transverse pipe portion 710 and a longitudinal pipe portion 720 that are arranged fixedly; the second hot water outlet pipeline 530 includes a third hot water outlet pipe section 531, a second Y-shaped three-way connector 532 and a fourth hot water outlet pipe section 533 which are fixedly connected in sequence, and the symmetrical two ends of the second Y-shaped three-way connector 532 are respectively connected to the water outlet end of the third hot water outlet pipe section 531 and the transverse pipe portion 710, and the third end of the second Y-shaped three-way connector 532 is connected to the water inlet end of the fourth hot water outlet pipe section 533. In this arrangement, the structure of the second connecting pipeline 700 is simple, and the second hot water outlet pipeline 530 is also basically arranged transversely, which is not only conducive to the flow of water, but also occupies a relatively small height space, which is conducive to reducing the overall height.

In the present embodiment, as shown in FIG. 3, the second connecting pipeline 700 is provided with a safety valve 810. When the first waterway system and the second waterway system are working, the safety valve 810 can timely relieve the pressure of the first hot water pipeline 300 and the second hot water pipeline 500. Of course, in other embodiments of the present application, the safety valve 810 can also be set in the second hot water pipeline 500.

In the present embodiment, as shown in FIG. 2, a target flow switch 830 is further provided between the three-way valve 332 and the first electric heater 320 and the second hot water inlet pipeline 510, which can also be called a water flow switch, for detecting the fluid in the hot water pipeline to effectively protect the electric heater, prevent the issues such as burning dry of the electric heater and excessive pressure in the waterway system due to too small flow rate, and ensure the normal operation of the waterway system.
