A fluid pump assembly 100 for a window air conditioner and a window air conditioner according to embodiments of the present disclosure will be described below with reference to FIGS. 1 to 8.

As illustrated in FIGS. 1 to 4, a fluid pump assembly 100 for a window air conditioner according to embodiments in a first aspect of the present disclosure includes a fluid pump 10 and a fixation shell 20.

The fluid pump 10 has a pipe connection structure 12 at an end portion of the fluid pump 10. The fluid pump 10 has a first positioning structure 11. The fixation shell 20 is adapted to be mounted in the window air conditioner. The fixation shell 20 is configured to accommodate the fluid pump 10. The fixation shell 20 has a closed end and an open end opposite to the closed end. The fixation shell 20 has a second positioning structure 21. The second positioning structure 21 is engaged with the first positioning structure 11 for positioning, to restrict the pipe connection structure 12 to correspond to the open end of the fixation shell 20. That is, a mounting orientation of the fluid pump 10 relative to the fixation shell 20 can be restricted.

The fluid pump 10 is arranged in the window air conditioner. The fluid pump 10 may supply condensed water collected in a water collection tray to a connection pipeline, and the connection pipeline will further supply the condensed water to a condenser to improve a heat exchange capacity of the condenser; or the connection pipeline will further spray the condensed water to a surface of other components in the window air conditioner to perform self-cleaning of the window air conditioner; or the connection pipeline will further discharge the condensed water after being filtered and atomized to an indoor side, to achieve humidification of the indoor side. However, a layout direction of the connection pipeline configured to guide a flowing direction of the condensed water has been determined in a design stage. The connection pipeline is located outside the fixation shell 20 and is opposite to the open end of the fixation shell 20. The pipe connection structure 12 of the fluid pump 10 needs to be in communication with the connection pipeline. Correspondingly, the pipe connection structure needs to protrude from the open end or be arranged opposite to the open end. Therefore, during the assembling of the fluid pump 10, the mounting of the fluid pump 10 has directionality. That is, the pipe connection structure 12 needs to face towards the connection pipeline, causing the mounting direction of the fluid pump 10 to be fixed. The end of the fluid pump 10 provided with the pipe connection structure 12 needs to face towards the open end of the fixation shell 20.

In the present disclosure, the first positioning structure 11 is arranged at the fluid pump 10, the second positioning structure 21 is arranged at the fixation shell 20. The first positioning structure 11 is engaged with the second positioning structure 21. In this way, the mounting orientation of the fluid pump 10 relative to the fixation shell 20 can be restricted. That is, the pipe connection structure 12 is ensured to face towards the open end of the fixation shell 20. The fixation shell 20 is fixed in the fixed position in the window air conditioner, and therefore a direction (i.e., directions of a water inlet and a water outlet) of the pipe connection structure 12 of the fluid pump 10 can be correspondingly restricted. As a result, a connection between the water inlet and the water outlet and the connection pipeline in the window air conditioner is simpler and more convenient. In addition, during the assembling, the mounting direction of the fluid pump 10 does not need to be identified. In this way, fool-proofing of the assembling of the fluid pump 10 can be achieved, and the mounting efficiency can thus be improved.

The first positioning structure 11 may be constructed as a positioning post, a positioning groove, a positioning hole 52, a positioning boss, and other structures. Correspondingly, the second positioning structure 21 may be constructed as a positioning hole 52, a positioning boss, a positioning post or a positioning groove, and other structures. Through concave-convex fit between the first positioning structure 11 and the second positioning structure 21, the limiting of the fluid pump 10 is achieved, and the mounting orientation of the fluid pump 10 can be reliably restricted. The first positioning structure 11 and the second positioning structure 21 may also be constructed as insertable engagement structures. While realizing the limiting of the mounting orientation, fixing stability and reliability of the fluid pump 10 on the fixation shell 20 can also be improved.

The fluid pump 10 may be constructed as a spray pump.

In the fluid pump assembly 100 for the window air conditioner according to the embodiments of the present disclosure, by disposing the first positioning structure 11 at the fluid pump 10 and disposing the second positioning structure 21 at the fixation shell 20, and further through positioning engagement between the first positioning structure 11 and the second positioning structure 21, the mounting position and mounting orientation of the fluid pump 10 are fixed. During the assembling of the fluid pump 10, the mounting orientation does not need to be identified, which can reduce the assembling difficulty. Moreover, during the assembling of the fluid pump assembly 100 in the window air conditioner, this arrangement allows the pipe connection structure 12 to correspond to the open end of the fixation shell 20 for ease of the connection between the pipe connection structure 12 of the fluid pump 10 and the connection pipeline. In this way, assembling efficiency can be further improved.

As illustrated in FIGS. 2 and 3, according to some embodiments of the present disclosure, a cross section of the end portion of the fluid pump 10 is constructed in a non-circular shape and has at least one corner. The end portion of the fluid pump 10 is formed as the first positioning structure 11.

The end portion of the fluid pump 10 with a water outlet is formed into a first positioning structure 11, and therefore a cross-section of the end portion of the fluid pump 10 with the water outlet is constructed in a non-circular shape. The non-circular-shaped structure has a good anti-rotation effect, which can achieve stable fixating of the fluid pump 10, and reduce a movement and shaking of the fluid pump 10 during operation. At same time, the end portion of the fluid pump 10 with the water outlet have at least one corner. Through engagement between the corner and the second positioning structure 21, an angle between the corner and a horizontal direction and/or a vertical direction can be fixed. Correspondingly, an orientation of the water outlet formed at the end portion of the fluid pump 10 can also be fixed to restrict the mounting orientation of the fluid pump 10.

As illustrated in FIGS. 1 and 4, the second positioning structure 21 is formed as a positioning groove, and the second positioning structure 21 is shaped to match the first positioning structure 11.

The corner at the end portion of the fluid pump 10 may be fitted into the positioning groove. Through the concave-convex fit between the corner and the positioning groove, the first positioning structure 11 is engaged with the second positioning structure 21 for limiting. While ensuring reliable limiting, a slight improvement in the structure of the fluid pump 10 and the structure of the fixation shell 20 can reduce cost.

The end portion of the fluid pump 10 has one corner that allows at least part of a cross-sectional area of the end portion of the fluid pump 10 to be in a “V” shape or a “U” shape. Correspondingly, the positioning groove is formed into a “V”-shaped groove or a “U”-shaped groove, that is, the second positioning structure 21 is shaped to match the first positioning structure 11. While realizing the limit of the mounting orientation, the fluid pump 10 is more attached to the fixation shell 20. In this way, fixing stability of the fluid pump 10 is higher, and stability and reliability of an operation of the fluid pump 10 are higher.

According to some embodiments of the present disclosure, the fixation shell 20 includes a first shell 22 and a second shell 23 that are opposite to each other in a radial direction of the fluid pump 10. An accommodation space configured to accommodate the fluid pump 10 is formed between the first shell 22 and the second shell 23. The second positioning structure 21 is formed at the first shell 22 and/or the second shell 23.

The first shell 22 and the second shell 23 are joined together to form the accommodation space. According to a demand for a space layout in the window air conditioner, the first shell 22 may be an upper shell, and the second shell 23 may be correspondingly a lower shell. The first shell 22 may be a left side shell, and the second shell 23 may be correspondingly a right side shell. The first shell 22 and the second shell 23 are arranged around the fluid pump 10 in the radial direction of the fluid pump 10, to enable the fluid pump 10 to be arranged between the first shell 22 and the second shell 23. At least the first shell 22 or the second shell 23 is provided with the second positioning structure 21 engaged with the first positioning structure 11 of the fluid pump 10, to fit with the second shell 23 or the first shell 22, after completing the assembling of the first shell 22 and the fluid pump 10 or the assembling of the second shell 23 and the fluid pump and achieving the limiting of the mounting orientation through the engagement between the first positioning structure 11 and the second positioning structure 21. In this way, assembling convenience of the fluid pump assembly 100 can be effectively improved.

The expression “the second positioning structure 21 is formed at the first shell 22 and/or the second shell 23” refers to that the second positioning structure 21 may be formed at the first shell 22 and may also be formed at the second shell 23. A plurality of second positioning structures 21 may also be provided, and arranged at each of the first shell 22 and the second shell 23.

As illustrated in FIG. 4, a wiring clip 24 is provided on a surface of the first shell 22 and/or the second shell 23 forming the accommodation space.

The wiring clip 24 may be arranged only at the first shell 22, or only at the second shell 23, or at each of the first shell 22 and the second shell 23. The fixation shell 20 has a wiring harness through hole, and the fluid pump 10 has an electrical connection terminal. A wiring harness passes through the wiring harness through hole and is electrically connected to the electrical connection terminal. A plurality of wiring clips 24 may be provided and sequentially arranged on a shortest path of the wiring harness extending from the wiring harness through hole to the electrical connection end. The wiring harness is fixed by the plurality of wiring clips 24 sequentially, which can improve stability and reliability of the fixing of the wiring harness. In this way, the wiring harness is avoided from shaking during the operation of the fluid pump 10 to reduce wear of the wiring harness. In addition, a welding cracking phenomenon is avoided to improve the stability, reliability, and safety of the operation of the fluid pump 10.

As illustrated in FIGS. 3 and 4, according to some embodiments of the present disclosure, the first shell 22 and the second shell 23 are fit with each other for positioning by a positioning assembly and/or fixedly connected to each other by a threaded connector.

The first shell 22 includes a first plate and a first enclosure plate arranged around the first plate. The second shell 23 includes a second plate and a second enclosure plate arranged around the second plate. The first plate, the first enclosure plate, the second plate, and the second enclosure plate form the accommodation space. The first enclosure plate and/or the second enclosure plate have a wiring harness through hole and an extending opening through which the water inlet and the water outlet of the fluid pump 10 extend. The wiring clip 24 is arranged at the first plate and/or the second plate.

The positioning assembly may include a positioning snap 51 and a positioning hole 52. The positioning snap 51 is formed at the first enclosure plate, and the positioning hole 52 is formed at the second enclosure plate; or the positioning snap 51 is formed at the second enclosure plate, and the positioning hole 52 is formed at the first enclosure plate. The positioning snap 51 is engaged with the positioning hole 52 for positioning to realize pre-positioning and a fixed connection of the first shell 22 and the second shell 23.

The fixation structure of the first shell 22 and the second shell 23 according to the embodiment of the present disclosure is not limited thereto. In other embodiments, the first shell 22 and the second shell 23 may be fixedly connected to each other by a threaded connector. For example, a stud 53 may be provided at the first plate, and a threaded hole 54 may be provided at the second plate correspondingly; or a stud 53 may be provided at the second plate, and a threaded hole 54 may be provided at the first plate correspondingly. Thus, the first shell 22 and the second shell 23 are fixedly connected to each other through the engagement between a fastener passing through the threaded hole 54 and the stud 53.

By enabling the first shell 22 to be fixedly connected to the second shell 23, the fluid pump 10 can be spaced apart from an ambient environment to prevent a user from touching the fluid pump 10. In this way, safety is improved.

The first shell 22 and the second shell 23 are fixedly connected to each other by the threaded connector while being fit with each other for positioning by the positioning assembly.

As illustrated in FIGS. 2 and 4, according to some embodiments of the present disclosure, a support rib 25 is provided in the fixation shell 20, and the support rib 25 is configured to support the fluid pump 10.

The support rib 25 may be arranged at each of the first plate and the second plate. A plurality of support ribs 25 may be provided at each of the first plate and the second plate. The plurality of support ribs at the first plate has a one-to-one correspondence with the plurality of support ribs at the second plate. A minimum distance between two opposite support ribs 25 is consistent with a diameter or a width of the fluid pump 10, to clamp and fix the fluid pump 10 by the support rib 25. In this way, while ensuring the stability and the reliability of fixing the fluid pump 10, a contact area between the fluid pump 10 and the fixation shell 20 can be reduced to alleviate a vibration impact of the fluid pump 10 on the fixation shell 20, and thus to effectively reduce an influence of noise and vibration during the operation of the fluid pump 10 on vibration and noise of the window air conditioner. In this way, use experience of the window air conditioner is improved.

As illustrated in FIG. 2, in some embodiments, the fluid pump assembly 100 further includes a buffer member 30 arranged around the fluid pump 10 and accommodated in the fixation shell 20.

The buffer member 30 may be constructed as a flexible member, such as a rubber member. The buffer member 30 is arranged around the fluid pump 10 and elastically pressed against by the support rib 25. On the one hand, the support rib 25 cooperates with the rubber member to fix the fluid pump 10, which can improve the stability and reliability of the fixing of the fluid pump 10. On the other hand, the buffer member 30 constructed as the flexible member can absorb an impact on the fluid pump 10 to further reduce the operation noise of the fluid pump assembly 100, and thus to effectively reduce the influence of the fluid pump assembly 100 on the operation noise and the vibration of the window air conditioner. In this way, the use experience is improved.

According to some embodiments of the present disclosure, the fixation shell 20 has a heat dissipation region.

In some embodiments, the heat dissipation region may be provided on the first shell 22. In some other embodiments, the heat dissipation region may also be provided on the second shell 23, or the heat dissipation region may be provided on each of the first shell 22 and the second shell 23, to dissipate the heat generated during the operation of the fluid pump 10 through the heat dissipation region to avoid overheating of the fluid pump 10. In this way, the stability, the reliability, and the safety of the operation of the fluid pump assembly 100 are improved.

The heat dissipation region is arranged at a side of the fluid pump assembly 100 facing towards an inner space of the window air conditioner, which can balance heat dissipation and noise suppression.

The heat dissipation region is formed by a heat dissipation grille 26, and a distance between adjacent grille bars of the heat dissipation grille 26 is smaller than or equal to 6 mm.

That is, the heat dissipation region is formed with the heat dissipation grille 26, and the distance between the adjacent grille bars of the heat dissipation grille 26 is smaller than or equal to than 6 mm. That is, a width of the adjacent grille bars may be 6 mm, 5 mm, 4 mm, etc. The distance between the grille bars is more reasonable. While ensuring the heat dissipation effect, experimental requirements are met to ensure safety in use.

A window air conditioner according to embodiments in a second aspect of the present disclosure includes an indoor unit and an outdoor unit. The indoor unit includes the fluid pump assembly 100 in the embodiments described above.

In an exemplary embodiment of the present disclosure, the window air conditioner is arranged at a windowsill. The indoor unit is located at an indoor side, and the outdoor unit is located at an outdoor side. The fluid pump assembly 100 is arranged at the indoor unit. A water collection tray is provided in the indoor unit and configured to collect condensed water generated during operation of the indoor unit. The water inlet of the fluid pump assembly 100 is in communication with the water collection tray, and the water outlet of the fluid pump assembly 100 is in communication with the connection pipeline. The water outlet and the water inlet of the fluid pump 10 are integrated at the pipe connection structure 12, and the pipe connection structure 12 is in communication with the connection pipeline and the water collection tray simultaneously.

The fluid pump 10 and the fixation shell 20 according to the embodiments of the present disclosure, through the positioning engagement between the first positioning structure 11 and the second positioning structure 21, may restrict an end of the fluid pump 10 with the pipe connection structure 12 to be located at an open end of the fixation shell 20 (that is, the pipe connection structure 12 protrudes out of the open end, or is adjacent to the open end and opposite to the open end), to facilitate assembling between the pipe connection structure 12 and the connection pipeline.

In the window air conditioner according to the embodiments of the present disclosure, by providing the above-mentioned fluid pump assembly 100, assembling efficiency of the window air conditioner can be improved, and stability and reliability of operation of the window air conditioner can be made higher.

As illustrated in FIGS. 5 and 8, the indoor unit of the window air conditioner includes a heat exchanger and a base 200. The base 200 includes a first side plate 230 and a second side plate 240 that are located at two sides of the heat exchanger and configured to support the heat exchanger. The first side plate 230 has a through hole 220. The fixation shell 20 is mounted at the base 200, the open end of the fixation shell 20 is arranged facing towards the first side plate 230. The pipe connection structure of the fluid pump 10 passes through the through hole 220.

The base 200 includes a bottom plate and a plurality of side plates surrounding the bottom plate. Two side plates opposite to each other in a length direction of the bottom plate are respectively defined as a first side plate 230 and a second side plate 240 (i.e., two side plates located at two sides of the heat exchanger). The first side plate 230 has a through hole 220. A assembling direction of the fixation shell 20 is further defined as a direction from the second side plate 240 towards the first side plate 230. Moreover, the open end of the fixation shell 20 is located at a side facing towards the first side plate 230, which can ensure that after the fixation shell 20 is assembled to the base 200, in a front viewing direction of the base 200, the open end and the through hole 220 are located at one side; and in a side viewing direction of the base 200 (see FIG. 8), a projection of the open end coincides with a projection of the through hole 220. In this way, the pipe connection structure 12 can be ensured to be in a horizontal direction, to ensure that the pipe connection structure 12 protruding out of the fixation shell 20 can pass through the through hole 220. As a result, the assembling between the pipe connection structure 12 and the connection pipeline is simpler and more convenient.

A plurality of through holes 220 may be provided, and each of the plurality of through holes 220 corresponds to a protruding pipe body of the pipe connection structure 12. One through hole 220 may also be provided, and a plurality of protruding pipe bodies passes through one through hole 220.

As illustrated in FIGS. 6 and 7, according to some embodiments of the present disclosure, the base 200 is provided with a first guide structure, and the fixation shell 20 has a second guide structure. The second guide structure is engaged with the first guide structure to restrict a mounting direction of the fixation shell 20 relative to the base 200.

The first guide structure may be constructed as a guide plate 210, and the second guide structure is correspondingly constructed as a guide groove 40 engaged with the guide plate 210; or the first guide structure may be constructed as a guide groove 40, and the second guide structure is correspondingly constructed as a guide plate 210 engaged with the guide groove 40, to realize a mounting guide of the fixation shell 20 on the base 200 through the engagement between the first guide structure and the second guide structure, and guide the fixation shell 20 to be assembled to the base 200 in a mounting direction from the second side plate 240 towards the first side plate 230. In this way, a wrong mounting and an inverted mounting are avoided while improving the assembling efficiency. In addition, a subsequent assembling between the pipe connection structure 12 and the connection pipeline are facilitated.

The first guide structure is formed as a guide plate 210, and the second guide structure is formed as a guide groove 40 engaged with the guide plate 210. The guide plate 210 includes a first plate member 211 and a second plate member 212 that are sequentially arranged in a direction from the first side plate 230 to the second side plate 240. The second plate member 212 extends obliquely towards a center of the base 200 relative to the first plate member 211.

The guide plate 210 is arranged at a bottom plate of the base 200. The guide plate 210 extends from the first side plate 230 towards the second side plate 240. The guide plate 210 is opposite to a side plate between the first side plate 230 and the second side plate 240. A guide groove 40 is formed between the first plate and the second plate of the fixation shell 20. When the guide plate 210 extends into the guide groove 40, it may be first guided by the second plate member 212 arranged obliquely relative to the first plate member 211. A distance between the second plate member 212 and a side plate opposite to the second plate member 212 gradually increases towards the second side plate 240, forming a flaring section, for ease of a butt-joint between the guide groove 40 and the guide plate 210. After the butt-joint is completed, the fixation shell 20 is assembled into a movement position through further guide of the first plate member 211. In this way, the assembling convenience of the fixation shell 20 is improved.

As illustrated in FIG. 7, the guide plate 210 further includes a stop member 213 located at a side of the first plate member 211 facing away from the second plate member 212, and the stop member 213 is configured to prevent the guide groove 40 from disengaging from the guide plate 210 from the end of the guide plate 210 at which the stop member 213 is arranged.

The stop member 213 is also constructed as a plate structure, and the second plate member 212 and the stop member 213 are arranged at two ends of the first plate member 211. The second plate member 212 performs the guide during an insertion of the fixation shell 20, and the stop member 213 at another end is configured to limit the fixation shell 20 to prevent disengagement of the guide groove 40. In this way, stability and reliability of the guiding engagement between the first guide structure and the second guide structure is improved.

By providing the stop member 213, there is an angle between the stop member 213 and the first plate member 211, and there is also an angle between the second plate member 212 and the first plate member 211. As a result, the guide plate 210 may be formed into a three-dimensional structure to improve the structural strength of the guide plate 210, and thus to avoid the guide plate 210 from breaking. In this way, reliability of the guiding engagement between the guide plate 210 and the guide groove 40 is improved.

The base 200 is further provided with at least two fixation structures, and the base 200 is connected to the fixation shell 20 by the at least two fixation structures.

The fixation structure may be constructed as a threaded through hole with an internal thread, and a fastener is in thread fit with the threaded through hole to achieve the fixing of the fixation shell 20 to the base 200. In order to avoid the fastener, a corresponding avoidance hole may be arranged at the first plate member 211 of the guide plate 210 for avoiding the fastener.

As illustrated in FIGS. 2 and 5, the fluid pump 10 is completely shielded by a side surface of the fixation shell 20 facing away from a center of the base 200. In this way, the fluid pump 10 may be spaced apart from an ambient environment to avoid accidental touch and improve the safety. At same time, the noise can be absorbed and reduced by the fixation shell 20, thereby reducing the impact of the operating noise of the fluid pump assembly 100 on the window air conditioner. In this way, the use experience of the window air conditioner is improved.
