The present subject matter relates generally to ice maker appliances, and particularly to standalone ice maker appliances, such as nugget ice makers.
Ice maker appliances, such as nugget ice makers and standalone ice maker appliances, include tubes that receive water at, and drain water from, the ice maker, and fluidly connect components of the ice maker appliance, such as between a reservoir and an ice engine for producing ice.
However, draining, cleaning, removing, or replacing such tubes can be difficult due to accessibility. For instance, tubes may be positioned within housings that are not generally intended for regular access. For example, access to the tubes may require removing fasteners (e.g., screws, bolts, etc.) using a tool to enter an internal volume of the ice maker.
Additionally, or alternatively, tubes may be located thermally proximate to heat sources, such as a heat exchanger for producing ice. Thermal proximity of the tubes can promote environmental conditions for generating mold, mildew, bacteria, viruses, scaling, or corrosion at the tube. Such conditions at a water supply tube to a reservoir or ice engine can lead to poor quality water being used for producing ice. Furthermore, mitigating such conditions by cleaning or replacement may be inhibited by poor or difficult access to the tubes.
Accordingly, an ice maker appliance that overcomes one or more of these issues would be beneficial and advantageous. Additionally, an ice maker appliance and method for operation that overcomes one or more of these issues would be beneficial and advantageous.

Embodiments of an ice maker appliance overcoming one or more of the aforementioned issues are provided. Referring to FIG. 1, a schematic embodiment of an ice maker appliance 100 is provided. The appliance 100 includes an ice engine 110 configured to produce ice. The ice engine 110 includes components generally understood for producing ice, such as, but not limited to, a heat exchanger for removing heat to produce ice, and a mechanism for moving ice to a container, such as an ice storage vessel 120. For instance, a tray, ramp, or chute 122 may provide a surface positioned to receive ice from the ice engine 110 and extending to deposit ice to the ice storage vessel 120. The ice engine 110 may include an auger for forming, shaving, or moving desired pieces of ice. The ice engine 110 may include trays for holding and molding pieces of ice into desired shapes. In particular embodiments, the ice engine 110 is configured as a nugget ice maker engine, such as configured to produce relatively small, soft, chewable ice compacted from ice shavings.
Various embodiments of ice engine 110 include a water supply opening 112 configured to receive water for producing ice. The ice engine 110 may include a flow control device, such as a flow control device or valve, configured to selectively articulate to receive water through the water supply opening 112 for producing ice.
The appliance 100 includes an upper reservoir 140 having an ice engine supply opening 142 and a water supply inlet opening 144. A water supply conduit 180 fluidly couples the upper reservoir 140 to the ice engine 110 to supply water to the ice engine 110 for producing ice. The water supply conduit 180 fluidly couples from the ice engine supply opening 142 at the upper reservoir 140 to the water supply opening 112 at the ice engine 110.
In various embodiments, the appliance 100 includes a lower reservoir 130 forming a receiving plenum 236 at which a user may deposit water for producing ice. The lower reservoir 130 includes a water supply outlet opening 134 and a return opening 136 in fluid communication with the receiving plenum 236. In various embodiments, an upper reservoir supply conduit 150 fluidly couples the lower reservoir 130 to the upper reservoir 140. The upper reservoir supply conduit 150 fluidly couples from the supply outlet opening 134 and receiving plenum 236 at the lower reservoir 130 to the supply inlet opening 144 and a receiving plenum 246 at the upper reservoir 140. In various embodiments, the return opening 136 at the lower reservoir 130 is positioned at a greater height than the supply outlet opening 134.
In various embodiments, a flow control device 160 is configured to selectively feed water through the upper reservoir supply conduit 150 from the lower reservoir 130 to the upper reservoir 140.
In some embodiments, the upper reservoir 140 includes a drain opening 146. A drain conduit 170 fluidly couples the upper reservoir 140 to the lower reservoir 130. The drain conduit 170 fluidly couples from the drain opening 146 at the upper reservoir 140 to the return opening 36 at the lower reservoir. The drain conduit 170 is configured to gravitationally feed water from the drain opening 146 at the upper reservoir 140 to the return opening 136 at the lower reservoir 130.
The upper reservoir 140 is positioned along a vertical direction relative to the lower reservoir 130 such that a plenum at the upper reservoir 140 at which water is received and stored is positioned to permit gravitational flow downward to the lower reservoir 130. Gravitational feeding of water from the upper reservoir 140 to the lower reservoir 130 is provided free of a fluid flow control device urging water from the upper reservoir 140 to the lower reservoir 130. For instance, various embodiments of the appliance 100 are configured without a pump, nozzle, valve, or other device configured to urge, push, actuate, or feed water from the drain opening 146 to the return opening 136 greater than a flow rate corresponding to gravitationally feeding water. As such, appliance 100 may be free of a flow control device from the drain opening 146 to the return opening 136. A flow path of the appliance 100 extending from the upper reservoir 140 to the lower reservoir 130 (e.g., through the drain conduit 170) may be configured as a passive system without actuating or articulating components. As a flow control device, such as a pump or valve, may generally provide a variable geometry or flow area along a volume extending from an upper reservoir to a lower reservoir, embodiments of the appliance 100 provided herein may include the drain conduit 170 having a substantially constant flow area from the drain opening 146 at the upper reservoir 140 to the return opening 136 at the lower reservoir 130.
The flow control device 160 may be configured to permit flow through the upper reservoir supply conduit 150 from the upper reservoir 140 to the lower reservoir when the flow control device 160 is deactivated. For instance, the flow control device 160 may include a centrifugal flow control device or any appropriate type of flow control device permitting back flow in a deactivated state.
In various embodiments, appliance 100 includes a water level sensor 190 configured to determine a water height at the upper reservoir 140, the lower reservoir 130, or both. The water level sensor 190 may include any appropriate float sensor or float switch. For instance, the water level sensor 190 may generally include an actuatable rod or member connected to a floatation device. Movement of the floatation device with the water level articulates the rod or member. Water height corresponds to the position of the floatation device, and changes in water height translate into changes in position of the articulatable rod or member. Changes in the position of the rod or member are coupled to a sensor or switch operably coupled to a flow control device (e.g., a pump or valve, such as flow control device 160) configured to selectively permit or inhibit flow of water to the upper reservoir 140.
In still various embodiments, the supply inlet opening 144 is positioned at the upper reservoir 140 at a height (e.g., along a vertical direction) greater than a maximum water level height 191 corresponding to the water level sensor 190 at the upper reservoir 140.
In some embodiments, the water level sensor 190 is operably coupled to the flow control device 160. As described herein, the flow control device 160 is operably coupled to the flow control device 160 to activate (e.g., articulate, open, energize, etc.) to supply water from the lower reservoir 130 to the upper reservoir 140 when the water level sensor 190 articulates, translates, or otherwise determines a water height at the upper reservoir 190 at or less than a minimum water level height 192. For instance, a flow sensor or switch at the flow control device 190 may be operably coupled to a member operably or communicatively coupled to the flow control device 160 to permit flow of water from the lower reservoir 130 to the upper reservoir 140 when the water height (e.g., a flotation device at the water level sensor 190) is at or below the minimum water level height 192. The flow control device 190 may further be configured to deactivate (e.g., articulate, close, de-energize, etc.) to discontinue supplying water from the lower reservoir 130 to the upper reservoir 140 when the water level sensor 190 articulates, translates, or otherwise determines the water height at the upper reservoir 140 at or greater than the maximum water level height 191.
In various embodiments, the upper reservoir supply conduit 150 and the supply outlet opening 134 at the lower reservoir 130 are configured to provide a greater flow rate to the lower reservoir 130 when the flow control device 160 is deactivated (i.e., discontinued from pulling water from the lower reservoir 130 to the upper reservoir 140) than gravitational feed of water from the drain opening 146 at the upper reservoir 140 to the return opening 136 at the lower reservoir 130. For instance, a geometry corresponding to flow rate across the drain opening 146, or a drain flow path at least in part from the drain opening 146 to the return opening 136, such as flow area, is less than a corresponding geometry (e.g., flow area) at the upper reservoir supply conduit 150, or a supply flow path from the supply outlet opening 134 to the supply inlet opening 144.
The appliance 100 includes drain opening 146, drain conduit 170, and return opening 136 configured to continuously permit flow of water from the upper reservoir 140 to the lower reservoir 130. Appliance 100 may enter into an idle mode after a period without interaction from a user (e.g., without having ice removed or generated). The idle mode can inhibit flow of water through upper reservoir supply conduit 150, or commands for water supply therethrough. For instance, idle mode may inhibit supply water based on a minimum water level at the upper reservoir 140. After a period of time in the idle mode, without water being pulled from the lower reservoir 130 to the upper reservoir 140 through upper reservoir supply conduit 150, water at the upper reservoir supply conduit 150 will drain back to the lower reservoir 130, permitting the upper reservoir supply conduit 150 to become dry and mitigate growth of undesired mold, mildew, bacteria, scaling, or viruses, or inhibit corrosion of the conduit 150. Water from the upper reservoir 140 may further drain through the drain opening 146 to the lower reservoir 130, permitting the upper reservoir 140 to become dry.
Referring still to FIG. 1, in various embodiments, the appliance 100 includes a lower reservoir egress conduit 195. The lower reservoir egress conduit 195 may form a drain conduit (e.g., to a sink or other disposal) or flow path to a second reservoir 135 positioned adjacent to the lower reservoir 130, such as forming a side tank. In such embodiments, the lower reservoir egress conduit 195 fluidly couples the lower reservoir 130 at an egress opening 138 to the second reservoir 135. The lower reservoir egress conduit 195 may include a quick-release fitting or valve 197, facilitating user articulation of flow from the lower reservoir egress conduit 195 (e.g., to the second reservoir 135, to a drain, or to a user as a water dispenser). Lower reservoir 130, upper reservoir 140, or both, may form a first reservoir at which water is filtered and provided to the second reservoir 135 as a filtered water tank.
Referring now to FIGS. 2A-2B and FIG. 3, embodiments of an ice maker appliance 100 are provided. FIG. 2A and FIG. 3 depict schematic embodiments of an appliance 100. FIG. 2B depicts a partially exploded view of components of an embodiment of the appliance 100. Appliance 100 depicted in FIGS. 2A-2B and FIG. 3 are configured substantially as described in regard to one or more embodiments of FIG. 1. In FIGS. 2A-2B and FIG. 3, the appliance 100 further includes a water filter 200 positioned at the upper reservoir 140. The water filter 200 is positioned fluidly upstream of the ice engine supply opening 142 and the ice engine 110, such as to provide filtration of water from the upper reservoir 140 flowing to the ice engine 110. The water filter 200 may include a gravity water filter in which water from the upper reservoir 140 flows substantially downward through a filtration medium at the water filter 200 and to the ice engine supply opening 142 and supply conduit 180 to the ice engine 110. The water filter 200 may additionally be configured for water to flow from the upper reservoir 140 substantially downward through the filtration medium at and to the drain opening 146 and drain conduit 170.
In various embodiments, the appliance 100 is free of a filter positioned at the lower reservoir 130 or between the flow control device 160 and the lower reservoir 130 (i.e., free of a filter fluidly upstream relative to a flow direction of water via the flow control device 160 from the lower reservoir 130 to the upper reservoir 140). Positioning the water filter 200 at the upper reservoir 140 may remove a need for a water filter at the lower reservoir 130, or fluidly proximate thereto. Removing a water filter from the lower reservoir 130, or from along a flow path from the lower reservoir 130 to the flow control device 160, may remove flow restrictions that can require configurations, flow or power ratings, back pressures or pressure differentials, or geometries at the flow control device 160 that may prevent backflow of water from the upper reservoir supply conduit 150 to the lower reservoir 130 when the flow control device 160 is deactivated or discontinued from urging flow toward the upper reservoir 140. For instance, some embodiments of a flow control device forming a diaphragm pump may inhibit backflow to the lower reservoir, which may cause water to remain in a feed conduit from a lower reservoir to an upper reservoir, which can facilitate undesired growth of mold, mildew, bacteria, viruses, scaling, or corrosion at the feed conduit.
Referring now to FIGS. 4-9, exemplary embodiments of a water filter 200 and an upper reservoir 140 are provided. FIG. 4 provides a perspective view of an embodiment of the water filter 200. FIGS. 5-6 provide exemplary cutaway perspective views of an embodiment of the water filter 200 positioned in an embodiment of the upper reservoir 140. FIG. 7-9 provide exemplary perspective views of an embodiment of the upper reservoir 140 with and without an embodiment of the water filter 200.
In various embodiments, the upper reservoir 140 includes a body 240 including a base wall 242 and a plurality of side walls 244. A door or top panel 243 extends over the plurality of side walls 244, such as to enclose the receiving plenum 246 formed between the plurality of side walls 244 and the base wall 242. Water supply inlet opening 144 is formed through at least one of the side walls 244. Water from the water supply inlet opening 144 is provided into the upper reservoir 140 at the receiving plenum 246. In various embodiments, the ice engine supply opening 142 and the drain opening 146 are formed through the body 240.
In various embodiments, the water filter 200 includes a filter body 210 at which a filtration medium 212 is positioned. The filtration medium 212 includes any appropriate type of material, substrate, or composition, such as, but not limited to, activated charcoal, catalytic carbon, sand, gravel, resin, polymers, or combinations thereof. The filtration medium 212 may include electrically-driven filter media or apparatuses.
In still various embodiments, a member 220 extends from the filter body 210 and positions a sensing interface 222 at a wall (e.g., wall 242, 243, 244) of the upper reservoir 140 in sensing proximity to a filter sensor 230 (FIGS. 7-9). The member 220 may extend substantially along a vertical direction, such as from the filter body 210 toward a door or top panel 243 of the upper reservoir 140.
The filter sensor 230 may be positioned outside of the body 240. The filter sensor 230 may abut an outside surface of the body 240, or position with a gap between the filter sensor 230 and the body 240. The filter sensor 230 may include any appropriate device for determining presence or proximity of a member. In some embodiments, the filter sensor 230 includes a proximity sensor having an inductive, magnetic, or capacitive sensor configured to magnetically or electromagnetically communicate with at least a portion of the member 220 having an appropriate sensing material, such as a metallic or ferrous material at the sensing interface 222. For instance, the filter sensor 230 may be electrically coupled to a power source or controller permitting electromagnetic communication of the filter sensor 230 to the sensing interface 222 inside or outside of the upper reservoir 140.
Referring to FIGS. 4-6, in some embodiments, the member 220 forms a hanger configured to extend around an upper lip 241 of the upper reservoir 140. The member 220 may form a hanger including a latch, curl, or hook 224 configured to extend over the upper lip 241. The member 220 forming a hanger may position the sensing interface 222 outside of the upper reservoir 140 to position the sensing interface 222 proximate to the filter sensor 230. The member 220 forming the hanger may position the sensing interface 222 outside of the receiving plenum 246.
Referring to FIGS. 7-9, in some embodiments, the member 220 extends toward the side wall 244 to position the sensing interface 222 within the upper reservoir 140 proximate to the filter sensor 230.
Embodiments of the upper reservoir 140 and filter sensor 230 may determine presence of the water filter 200 at the upper reservoir 140 without requiring electrical or electronic components or wires to extend through one or more, or all, of wall 242, 243, 244 of the upper reservoir 140. In some embodiments, the body 240 of the upper reservoir 140 is free of electrical or electronic components extending through the body 240 (e.g., extending through one or more walls 242, 243, 244) into the receiving plenum 246.
Referring back to FIGS. 5-6, in various embodiments, the filter body 210 may include a plug or metering member 214 extendable from the filter body 210 into the drain opening 146 at the upper reservoir 140. In various embodiments, the member 214 extends vertically downward from the filter body 210 to extend into the drain opening 146. A user may articulate the water filter 200 along the vertical direction to position the water filter 200 at the upper reservoir 140, or pull the water filter 200 along the vertical direction to remove the water filter 200 from the upper reservoir 140. The user may furthermore articulate the water filter 200 along the vertical direction to position the member 214 into the drain opening 146, or remove the member 214 from the drain opening 146.
Referring to FIG. 5, the member 214 forms a plug extending into the drain opening 146 to prohibit flow through the drain opening 146 into the drain conduit 170. The member 214 extending from the filter body 210 may correspond in geometry to the drain opening 146 to prohibit flow from the upper reservoir 140 into the drain conduit 170.
Referring to FIG. 6, the member 214 forms a metering member extending into the drain opening 146 to inhibit flow through the drain opening 146 into the drain conduit 170, such as to provide a metered flow rate of water from the upper reservoir 140 through the drain conduit 170. A geometry of the member 214 may be configured relative to the drain opening 146 to adjust a flow area to the drain conduit 170, such as to produce a flow rate through the drain conduit 170 less than a flow rate at the upper reservoir supply conduit 150. For instance, member 214 may extend into the drain opening 146 and form a gap 147 between the member 214 and surrounding walls at the reservoir 140.
Referring to FIG. 2B and FIGS. 5-9, the upper reservoir 140 may include a water filter plenum 245 at which the water filter 200 is received into the upper reservoir 140. The water filter plenum 245 may extend into the base wall 242 to form a pocket at which the water filter 200 is positioned at the upper reservoir 200. The upper reservoir 140 may include a plenum side wall 247 and a plenum base wall 248 forming the water filter plenum 245. In various embodiments, walls 247, 248 extend from the base wall 242, such as downward along the vertical direction and forming a trough into the base wall 242. The ice engine supply opening 142 and drain opening 146 may extend through the plenum side wall 247 or the plenum base wall 248. As such, the water filter 200 is disposable in fluid arrangement between the receiving plenum 246 and the ice engine supply opening 142, the drain opening 146, or both.
Referring back to FIG. 3, and further depicted in FIGS. 5-9, in various embodiments, the upper reservoir 140 includes a flow separation wall 143 extending from the drain opening 146 and into the receiving plenum 246. The flow separation wall 143 forms a bypass passage 145 extending from a bypass inlet opening 148 to the drain opening 146. The bypass passage 145 fluidly bypasses the water filter 200 from the receiving plenum 246 to the drain opening 146.
The bypass inlet opening 148 is positioned at a height at the receiving plenum 146 greater than the filter body 210 of the water filter 200. In various embodiments, the bypass inlet opening 148 is positioned at the height at the receiving plenum 146 less than a vertical position the water supply inlet opening 144.
Referring to FIG. 3, in some embodiments, the drain opening 146 includes a first drain opening 146A fluidly downstream of the water filter 200, such as in fluid communication with the water filter 200 to receive filtered water from the water filter 200. The drain opening 146 may further include a second drain opening fluidly downstream of the bypass passage 145, such as forming an end of the bypass passage 145 fluidly bypassing the water filter 200. Drain openings 146A, 146B may together fluidly connect to the drain conduit 170. For instance, drain openings 146A, 146B may fluidly couple to the lower reservoir 130, such as described herein in regard to drain opening 146.
In some embodiments, the flow separation wall 143 may include a tube, manifold, or conduit extending from the drain opening 146 and positioned to receive water from the receiving plenum 246. In still some embodiments, referring to FIGS. 7-9, the flow separation wall 143 extends along an inner wall of the upper reservoir 140 to the water filter plenum 245 at which the water filter 200 is disposed. For instance, referring to FIGS. 7-9, the flow separation wall 143 may extend along the plenum side wall 247, the side wall 244, or both. The flow separation wall 143 may be formed integrally with the body 240 as a unitary, monolithic component.
The flow separation wall 143 may additionally form a raised surface at the water filter plenum 245. The water filter 200, such as the filter body 210, may include a notch 226 (FIG. 9) corresponding to the flow separation wall 143. As such, raised surface of the flow separation wall 143 at the water filter plenum 245 may form a clocking or orienting feature of the water filter 200 into the water filter plenum 245, such as may position the member 220 or sensing interface 222 in operable arrangement with the filter sensor 230.
Embodiments of the flow separation wall 143 and bypass passage 145 may form an overflow port permitting flow of water from the upper reservoir 140 to the drain conduit 170 without requiring flow through the water filter 200. The overflow port can facilitate removing a float sensor or water level sensor from the upper reservoir 140. As such, various embodiments of the appliance 100 may prevent overflow at the upper reservoir 140 without requiring electrical or electronic components or wires to extend through one or more, or all, of wall 242, 243, 244 of the upper reservoir 140. In some embodiments, the body 240 of the upper reservoir 140 is free of electrical or electronic components extending through the body 240 (e.g., extending through one or more walls 242, 243, 244) into the receiving plenum 246.
In an exemplary embodiment of a method for operating the appliance 100, the flow control device 160 operates to flow water to the upper reservoir 140 when, or before, the ice engine 110 operates to produce ice. For instance, the ice engine 110 operates to receive water from the upper reservoir 140, and further operates a cooling system (e.g., a heat exchanger) to generate ice. A shutdown operation may include discontinuing the cooling system then discontinuing operation of the ice engine 110, the flow control device 160, or both.
In an exemplary embodiment of a method for operating the appliance 100, a circulation or cleaning mode may include cycling or pulsing flow through or from the flow control device 160. The ice engine 110 can receive and circulate water with the cooling system remaining off. Water flows from the lower reservoir 130 to the upper reservoir 140. As flow across the water filter 200 may slow a flow rate to the drain opening 146, water may accumulate in the receiving plenum 246 until the water level height rises to the bypass inlet opening 148 and through the bypass passage 145 to the drain conduit 170 and to the lower reservoir 130. The second drain opening 146B and drain conduit 170 may be sized to permit a flow rate to the lower reservoir 130 facilitating circulation such as described. The first drain opening 146A may be sized such as described herein to meter or prohibit flow such as described herein. In various embodiments, the first drain opening 146A is configured to feed water from the first drain opening 146A to the drain conduit 170 at a first flow rate less than a second flow rate corresponding to the second drain opening 146B configured to feed water from the second drain opening 146B to the drain conduit 170. In still various embodiments, the member 214 extending from the filter body 210 is configured to extend into the first drain opening 146A and permit a first flow rate of water from the upper reservoir 140 through the first drain opening 146A to the drain conduit 170. The first flow rate is less than a second flow rate corresponding to the second drain opening 146B (e.g., without member 214 extending thereinto) configured to feed water from the second drain opening 146B to the drain conduit 170.
The circulation or cleaning mode may activate after a predetermined quantity of ice engine operation (e.g., ice production) cycles or hours, or after a predetermined period of time in an idle mode, such as may inhibit growth of mold, mildew, bacteria, viruses, scaling, or corrosion. In still some embodiments, the flow control device 160, the ice engine 110, or both, may be communicatively coupled to the water level sensor 190 at the lower reservoir 130, such as may prevent overflow or overfill of water at the lower reservoir 130 by selectively operating the flow control device 160 to remove water from the lower reservoir 130 to the upper reservoir 140.
Referring now to FIG. 10, an embodiment of the upper reservoir 140 including an articulatable door or top panel 243 is provided. The articulatable top panel 234 permits selective access into the upper reservoir 140, such as into the receiving plenum 246. For instance, the upper reservoir 140 may include the body 240 including walls 242, 244, or furthermore, plenum walls 247, 248, forming an integral, unitary, monolithic component. Top panel 243 may form a separable component, such as a lid, window, or door, disposable over the upper lip 241 of the body 240.
In some embodiments, the top panel 243 may include a window or door 345 permitting selective access into the upper reservoir 140, such as into the receiving plenum 246. The top panel 243 may be formed integrally with the body 240, and the door 345 may form a separable component disposable to the top panel 243. A hinge 343 may connect the door 345 to the top panel 234 in rotatable connection. In other embodiments, the door 345 may be positioned in sliding arrangement to the top panel 243.
Embodiments of the upper reservoir 140 may facilitate the water filter 200 to operably couple to the water filter sensor 230 without requiring extension of electrical or electronic components through side walls 244, base wall 242, or plenum walls 247, 248 of the body 240. For instance, filter sensor 230 may mount to, or through, the top panel 243, such as at door 343, in operable communication with the member 220 or sensing interface 222 at the water filter 200.
In some embodiments, the upper reservoir 140 may facilitate the water filter 200 to operably couple to the water level sensor 190 without requiring extension of electrical or electronic components through side walls 244, base wall 242, or plenum walls 247, 248 of the body 240. For instance, electrical or electronic components may extend through the top panel 243, such as through door 345, without requiring extension of electrical or electronic components through side walls 244, base wall 242, or plenum walls 247, 248 of the body 240.
Referring to FIG. 11, a schematic embodiment of an ice maker appliance 100 is provided. FIG. 12 depicts a partially exploded view of components of the appliance 100 in accordance with the schematic embodiment of FIG. 11. FIG. 13 depicts an embodiment of the upper reservoir 140 and various components of the appliance 100 of FIG. 12. The embodiments of the appliance 100 depicted in FIGS. 11-13 include components such as described in regard to one or more embodiments of FIGS. 1-10. Referring to FIGS. 11-13, the water supply inlet opening 144 may be configured as a direct plumb-in connection to a main water supply 90, such as a main water source to a residence, office, or other edifice, such as may be coupled to a main water supply including a municipal water system or well-water system. In such embodiments, the upper reservoir supply conduit 150 fluidly couples to the water supply inlet opening 144 to provide water from the main water supply 90 to the upper reservoir 140. The flow control device 160 may form an articulatable valve configured to selectively permit flow of water through the upper reservoir supply conduit 150 to the upper reservoir 140. The flow control device 160 may include a manually articulatable valve, an electrically or electronically operable solenoid valve, or other appropriate type of manual or automatic selectively permissible flow device.
In such embodiments, a second or lower reservoir may be obviated, as water for producing ice is provided from the main water supply 90 to the upper reservoir 140.
In various embodiments, such as described herein, the water level sensor 190 is positioned at the upper reservoir 140 and communicatively coupled to the flow control device 160 to selectively articulate and permit or urge flow of water to the upper reservoir 140. The water filter 200 positioned at the upper reservoir 140 is configured to filter water before entering the ice engine 110. The member 214 may form a plug at the drain opening 146, such that water from the upper reservoir 140 may drain through drain conduit 170 when the water filter 200 is removed from the upper reservoir 140. The drain conduit 170 may be fluidly coupled to a main drain system, such as fluidly coupled to a main sewage system or septic system.
Upper reservoir 140 may include embodiments of the articulatable top panel 243 such as described herein (e.g., at FIG. 10), such as may facilitate positioning and removal of the water filter 200 into the upper reservoir 140. Additionally, the articulatable top panel 243 may facilitate positioning of the sensing interface 222 at the water filter 200 in operable communication with the filter sensor 230, such as described herein.
Various embodiments of the direct plumb-in configuration may include openings positioned at heights or distances from a maximum water level height 191 in accordance with residential or commercial regulations or codes. For instance, the water supply inlet opening 144 may be positioned approximately one inch or more from the maximum water level height 191. Plumbing fittings at the openings may include any appropriate type of fitting as may be understood for direct plumb-in to a residential or commercial water source.
In such embodiments, a need for a supply conduit extending in fluid communication from a lower reservoir to an upper reservoir may be obviated, such as may further remove issues associated with undesired growth of mold, mildew, bacteria, viruses, scaling, or corrosion at a conduit configured to provide water from the lower reservoir to the upper reservoir. Additionally, or alternatively, removing a separate second or lower reservoir can facilitate forming the first or upper reservoir as an integral, unitary, monolithic body with fewer conduits between components, which may further facilitate housing the ice maker appliance within a cabinet having a smaller volume, or permit further space between heat-generating components (e.g., the heat exchanger for the ice engine 110) and volumes at which water is retained or flowed (e.g., conduits, reservoirs, plenums, etc.), which may further facilitate removing issues associated with undesired growth of mold, mildew, bacteria, viruses, scaling, or corrosion.
Referring to FIG. 12, in some embodiments, the ice storage vessel 120 may include a catchment volume 124 positioned below an ice storage volume 126. A perforated wall 128 permits flow of ice melt water from the ice storage volume 126 to the catchment volume 124. A drain conduit 172 extends in fluid communication from the catchment volume 124 to a drain. In some embodiments, the drain conduit 172 may fluidly connect (e.g., tee) to the drain conduit 170 extending in fluid communication from the upper reservoir 140 to a drain.
Referring still to FIG. 12, and to FIGS. 14-15, in various embodiments, the appliance 100 includes a housing 310 including a storage volume, such as may retain cleaning tools, cups, vessels, drinking utensils, or other components that may be complimentary or ancillary to operation or use of the appliance 100. The housing 310 includes a body 312 having a plurality of walls forming an internal volume 316 for storage. An articulatable door 314 provides selective access to the internal volume 316. For instance, FIG. 14 depicts the door 314 in a closed position, and FIG. 15 depicts the door 314 rotated (e.g., along a hinge 318) to an opening position. The hinge 318 may be connected to the body 312 of the housing 310, such as may facilitate coupling the door 314 in rotatable arrangement to the body 312.
In some embodiments, the articulatable door 314 and storage volume 316 are positioned beneath the ice storage vessel 120. For instance, the storage volume 316 may be positioned at a volume supplanting a lower reservoir volume. The door 314 may be positioned along a front face of the appliance 100, such as substantially co-planar to a front face or opening of the ice storage vessel 120.
Referring now to FIGS. 16-18, views of an embodiment of components of an appliance 100 are provided. Views provided in FIGS. 16-18 exclude certain components for clarity, such as, but not limited to, the ice chute 122 extending from the ice engine 110 to the ice storage vessel 120, or various electronics and user interfaces. Embodiments of the appliance 100 depicted in FIGS. 16-18 may be configured substantially such as depicted and described in regard to FIG. 2B, FIG. 3, and FIGS. 7-9. In FIGS. 16-18, embodiments of the housing 310 include the lower reservoir 130 and the water supply outlet opening 134 and return opening 136. The ice storage vessel 120 may be positioned vertically above the lower reservoir 130. In various embodiments, the housing 310 may include the door and internal storage volume, such as described in regard to FIGS. 14-15.
In various embodiments, the housing 310 includes a groove or passageway 350 formed into one or more walls of the body 312. The passageway 350 may form an indentation into the body 312, such that a conduit (e.g., the upper reservoir supply conduit 150) is disposable into the body 312 at the passageway 350. The conduit is substantially housed in the passageway 350 (e.g., along at least 50% of a length of the conduit, or at least 60% of the conduit, or at least 75% of the conduit, or at least 90% of the conduit). The passageway 350 indented into the housing 310 embeds fluid tubes and conduits thereinto to avoid exposure to heat, such as heat from a heat exchanger or cooling system of the ice engine 110, heat generated from a controller, display, or other electronic device, or other heat-generating components. As such, the housing 310 may form a heat shield or insulating wall that may mitigate or eliminate exposure of the conduit (e.g., the upper reservoir supply conduit 150) to heat, such as may mitigate growth of mold, mildew, bacteria, viruses, scaling, or corrosion at the conduit.
In some embodiments, the appliance 100 receives the flow control device 160 directly onto the housing 310 at the water supply outlet opening 134, such as may eliminate a need for a tube or conduit extending from the water supply outlet opening 134 to the flow control device 160. The housing 310 may facilitate direct fluid coupling of the flow control device 160 to the receiving plenum 236 at the lower reservoir 130. Eliminating a need for a tube or conduit extending from a water supply opening to a flow control device may facilitate reducing a fluid flow path distance of the appliance, which may promote a pressure drop from end to end of a conduit that can facilitate various types of flow control device configurations, such as various configurations of pump, impeller, nozzle, etc., which may further facilitate a flow control device configuration permitting drainage of the upper reservoir supply conduit 150 during deactivation, such as may mitigate growth of mold, mildew, bacteria, viruses, scaling, or corrosion at the conduit.
Embodiments of the housing 310 may include an integral, unitary, monolithic structure including the ice storage vessel 120, the lower reservoir 130, and openings such as described herein. The monolithic housing 310 may facilitate positioning the ice maker appliance within a cabinet having a smaller volume, or permit further space between heat-generating components (e.g., the heat exchanger for the ice engine 110) and volumes at which water is retained or flowed (e.g., conduits, reservoirs, plenums, etc.), which may further facilitate removing issues associated with undesired growth of mold, mildew, bacteria, viruses, scaling, or corrosion.
Referring now to FIGS. 19-20, a side view of an embodiment of the appliance 100 is provided. The embodiment depicted in FIGS. 19-20 is configured substantially as depicted and described in regard to FIG. 18. FIGS. 19-20 further depict a cabinet 300 surrounding components of the ice maker appliance 100 such as described in regard to various embodiments herein. The cabinet 300 includes a plurality of outer walls 302 forming an interior or internal volume 304 at which various components of the appliance 100 are at least partially positioned, such as, but not limited to, the ice engine 110, the ice storage vessel 120, the reservoirs 130, 140, conduits 150, 170, 180, and electrical, electronic, sensor, display, and user interface apparatuses. The plurality of walls 302 include a door or articulatable panel 320 extending along a side of the appliance corresponding substantially to the housing 310 and passageway 350 at the body 312. The articulatable panel 320 is configured to slide, rotate, or otherwise displace to provide selective user access to the internal volume 304 within the cabinet 300. The articulatable panel 320 extending alongside the passageway 350 may permit a user to access one or more conduits (e.g., upper reservoir supply conduit 150) for cleaning, replacement, repair, or servicing.
Referring now to FIG. 21, a schematic embodiment of the appliance 100 is provided. The appliance 100 may be configured substantially as described in regard to various embodiments depicted and described herein, such as FIG. 11. The upper reservoir 140 may include side walls 244 extending vertically below the water filter 200 to form a lower or second receiving plenum 236. The second receiving plenum 236 is positioned fluidly downstream of the water filter 200 and the first receiving plenum 246. In various embodiments, upper reservoir 140 includes walls 242, 244, 247, 248 forming an integral, unitary, monolithic component including the first receiving plenum 246, the water filter plenum 245, and the second receiving plenum 236.
The reservoir 140 includes an egress opening 138 in fluid communication with the second receiving plenum 236 at which egress conduit 195 fluidly couples. Conduit 195 may be fluidly coupled to fitting 197 forming a release valve or spigot configured to permit selective user flow of water from the second receiving plenum 236. Valve or fitting 197 may be mounted to the cabinet 300, such as may permit selective discharge of water from the reservoir (e.g., fresh water supply to the user). The second receiving plenum 236 may form a filtered water tank receiving filtered water from the water filter 200. As such, a portion of water filtered from the water filter 200 is directed to the ice engine 110 and a portion of water filtered from the water filter 200 is directed to the second receiving plenum 236 for user consumption.
In such embodiments, a need for a supply conduit extending in fluid communication from a lower reservoir to an upper reservoir may be obviated, such as may further remove issues associated with undesired growth of mold, mildew, bacteria, viruses, scaling, or corrosion at a conduit configured to provide water from the lower reservoir to the upper reservoir. Additionally, or alternatively, removing a separate second or lower reservoir can facilitate forming the first or upper reservoir as an integral, unitary, monolithic body with fewer conduits between components, which may further facilitate housing the ice maker appliance within a cabinet having a smaller volume, or permit further space between heat-generating components (e.g., the heat exchanger for the ice engine 110) and volumes at which water is retained or flowed (e.g., conduits, reservoirs, plenums, etc.), which may further facilitate removing issues associated with undesired growth of mold, mildew, bacteria, viruses, scaling, or corrosion.
