Patent Application
20250172330
The present subject matter relates generally to refrigerator appliances, and more particularly to supplying water to ice and water dispensers in refrigerator appliances.
Refrigerator appliances generally include a cabinet that defines one or more chilled chambers for receipt of food articles for storage. Typically, one or more doors are rotatably hinged to the cabinet to permit selective access to food items stored in the chilled chamber. Further, refrigerator appliances commonly include ice making assemblies mounted within an icebox on one of the doors or in a freezer compartment. The ice is stored in a storage bin and is accessible from within the freezer chamber or may be discharged through a dispenser recess defined on a front of the refrigerator door.
A typical side-by-side refrigerator with an external ice and water dispenser has one water line going into the door through the bottom hinge. In this design the icemaker is located in the case. Some refrigerators have the icemaker located on the freezer door. Typically, this design has two water lines going through the bottom hinge—one line for the ice maker and one for the water dispenser. This design has the potential for the water lines to break after many door opening cycles, e.g., because the lines must rotate around a vertical axis that is between the two tubes causing some stress in the material each time the door is opened and closed. In addition, to remove the door during installation, two water lines must be disconnected and reconnected essentially doubling the chance for a leak. Moreover, when a freezer door houses a water dispenser and two icemakers (e.g., one for standard ice and one for craft ice), three water lines are required to go through the bottom door hinge, further complicating reliability and service complexity.
Accordingly, a refrigerator appliance with features for improved water management would be desirable. More particularly, a refrigerator appliance with features for addressing common issues associated with getting water to door ice makers and water dispensers would be particularly beneficial.
Aspects and advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.

Referring now generally to
Dispensing assembly 140 and its various components may be positioned at least in part within a dispenser recess 142 defined on freezer door 130. In this regard, dispenser recess 142 is defined on a front side 112 of refrigerator appliance 100 such that a user may operate dispensing assembly 140 without opening freezer door 130. In addition, dispenser recess 142 is positioned at a predetermined elevation convenient for a user to access ice and enabling the user to access ice without the need to bend-over. In the exemplary embodiment, dispenser recess 142 is positioned at a level that approximates the chest level of a user.
Dispensing assembly 140 includes an ice dispenser 144 including a discharging outlet 146 for discharging ice from dispensing assembly 140. An actuating mechanism 148, shown as a paddle, is mounted below discharging outlet 146 for operating ice or water dispenser 144. In alternative exemplary embodiments, any suitable actuating mechanism may be used to operate ice dispenser 144. For example, ice dispenser 144 can include a sensor (such as an ultrasonic sensor) or a button rather than the paddle. Discharging outlet 146 and actuating mechanism 148 are an external part of ice dispenser 144 and are mounted in dispenser recess 142.
As shown in
A control panel 160 is provided for controlling the mode of operation. For example, control panel 160 includes one or more selector inputs 162, such as knobs, buttons, touchscreen interfaces, etc., such as a water dispensing button and an ice-dispensing button, for selecting a desired mode of operation such as crushed or non-crushed ice. In addition, inputs 162 may be used to specify a fill volume or method of operating dispensing assembly 140. In this regard, inputs 162 may be in communication with a processing device or controller 164. Signals generated in controller 164 operate refrigerator appliance 100 and dispensing assembly 140 in response to selector inputs 162. Additionally, a display 166, such as an indicator light or a screen, may be provided on control panel 160.

According to the illustrated embodiments, refrigerator appliance 100 may include a first icemaker 202 (e.g., a main icemaker associated with dispensing assembly 140 for discharging ice through ice dispenser 144) and a second icemaker 204 (e.g., a secondary icemaker such as a craft icemaker). According to example embodiments, each of first icemaker 202 and second icemaker 204 are mounted to freezer door 130, e.g., within icebox 150. According to example embodiments, each of first icemaker 202 and second icemaker 204 may have a dedicated storage bin 152 for storing ice. For example, first icemaker 202 may have a cover that allows chilled air to flow in from freezer chamber 124 to increase icemaking rate. By contrast, second icemaker 204 may have a cover to slow the ice freezing rate, e.g., which may facilitate the production of higher quality cubes. In addition, according to an example embodiment, first icemaker 202 may include a dispensing type of bucket and motor that would supply ice to discharging outlet 146 of dispensing assembly 140 (or alternatively could include an ice storage bin with no external dispenser). By contrast, second icemaker 204 may include an ice bin that has no dispensing system.

Conventional refrigerator appliances 100 include a dedicated water supply line for each water consuming device on the freezer door. Accordingly, conventional refrigerator appliances may utilize a dedicated water dispenser supply line and a dedicated icemaker supply line for each icemaker on the freezer door. Each of these supply lines may be routed through a door hinge. However, as explained above, an increase in the number of supply lines passing through a door hinge increases the likelihood of leaks, complicates appliance assembly in repairs, etc. For example, too many supply lines may result in the twisting or abrasion of supply lines in the confined space provided by the door hinge. Accordingly, aspects of the present subject matter are generally directed to improving water dispensing systems that simplify assembly, improve appliance performance, and mitigate or eliminate the likelihood of water leaks. Although exemplary water supply system configurations will be described herein, it should be appreciated that variations and modifications may be made while remaining within the scope of the present subject matter.
According to the illustrated embodiments of
As shown in
As illustrated, the flow of water through water dispenser supply line 230 is regulated by the operation of the water dispenser (e.g., via actuating mechanism 148). Notably, it may be desirable to regulate the supply of water from icemaker supply line 232 to each of first icemaker 202 and second icemaker 204. Accordingly, water supply systems 200, 300 may further include a first multi-way valve 240 that is fluidly coupled to the icemaker supply line 232. For example, referring now also to
As illustrated, first multi-way valve 240 may include a plurality of solenoid valves 246 that may be selectively open and to direct the flow of water through one or more respective outlets 244 to one or more of first icemaker 202 and second icemaker 204. Specifically, first multi-way valve 240 is illustrated as a double solenoid valve. Although first multi-way valve 240 is illustrated as multiple chamber solenoid valve, it should be appreciated that other valve types and constructions may be used while remaining within the scope of the present subject matter.
Referring now specifically to
According to an example embodiment, junction housing 250 may be positioned on an opposite side of freezer door 130 relative to hinges 210, 212. In this regard, icemaker supply line 232 may pass into freezer door 130 through lower hinge 212 and may be routed through an interior of freezer door 130 to junction housing 250. Junction housing 250 may generally define an inlet aperture 252 through which icemaker supply line 232 may be routed through interior door into a connection chamber 254 of junction housing 250. It should be appreciated that junction housing 250 may include other suitable configurations and positions while remaining within the scope of the present subject matter.
According to example embodiments, water supply systems 200, 300 may further include a first supply line 260 that provides fluid communication between a first outlet of the plurality of outlets 244 and first icemaker 202. Similarly, water supply systems 200, 300 may further include a second supply line 262 that provides fluid communication between a second outlet of the plurality of outlets 244 and second icemaker 204. Accordingly, by regulating the operation of solenoid valves 246, first multi-way valve 240 may selectively direct the flow of water to each of first icemaker 202 and second icemaker 204.
Referring now specifically to the water supply system 200 illustrated in
Referring now specifically to
As explained herein, aspects of the present subject matter are generally directed to a side-by-side refrigerator that includes dual ice makers (e.g., a main ice maker and a secondary ice maker) and a water dispenser installed in the freezer door with various water supply line configurations. According to example embodiments, a maximum of two water supply lines are installed in the door hinge to supply water to the ice makers and the water dispenser.
According to an example water supply configuration, tap water goes through a filter in the fresh food compartment. The filtered water is stored in the water tank and the cold water is supplied to the water dispenser and a first 3-way valve, then the first 3-way valve supplies the filtered water to a second 3-way valve (installed inside the freezer door through the door hinge), which supplies warm water to the main and the secondary ice makers.
According to yet another example water supply configuration, tap water goes through a filter and a water tank in the fresh food compartment. The filtered water is stored in the water tank and is supplied to a first 3-way valve, which supplies cold water to the water dispenser and a second 3-way valve (installed inside the freezer door through the door hinge). Then, the second 3-way valve supplies cold water to the main and the secondary ice makers.
