Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigerator. Background Technology

[0002] Currently, there is an increasing demand for water dispensing and ice-making functions in refrigerators. A refrigerator includes a water system, which distributes water to the water dispensing and ice-making sections via valves within the system.

[0003] In related technologies, refer to Figure 2 First, the water source is distributed through a one-in-three-out water valve A, with one path leading to the first ice maker, one path leading to the second ice maker, and one path leading to the water storage tank. The water in the water storage tank is then distributed a second time through a one-in-two-out water valve B, leading to the first water dispenser and the second water dispenser respectively.

[0004] In the above technical solution, if the first and second water dispensers need water, the one-in-three-outlet valve A and the one-in-two-outlet valve B need to be opened simultaneously.

[0005] The water source and software need to coordinate the opening and closing sequence of multiple valves, which not only increases the complexity of the control logic, but also easily causes the water pressure to rise and fall suddenly due to the asynchronous opening and closing of valves. Such fluctuations will directly impact components such as water tanks. Long-term use can easily cause damage to the water tank due to thermal expansion and contraction, and may even affect the water supply stability of the ice maker components inside the box and the water dispenser components in the door.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

[0007] This application addresses, to at least some extent, one of the technical problems in the related art.

[0008] Therefore, this application aims to provide a refrigerator that includes at least two ice makers and at least two water dispensers, and is equipped with a first water valve and a second water valve, wherein the water outlet of the first water valve and the second water valve are respectively configured to correspond to the ice makers and the water dispensers, thereby simplifying the complexity of the control logic and improving the stability of the water supply.

[0009] In a first aspect, embodiments of this application propose a refrigerator, which includes a cabinet, a door, an ice maker assembly, a water dispenser assembly, and a water system. The cabinet defines a refrigerator compartment and a freezer compartment. The door is rotatably connected to the cabinet for opening or closing the refrigerator compartment and the freezer compartment. The ice maker assembly includes at least two ice makers, and the water dispenser assembly includes at least two water dispensers. The water dispensers are disposed in the door or the refrigerator compartment. The water system is used to connect a water source to the ice maker and the water dispenser. The water system includes a water outlet connector, a first water valve, and a second water valve. The inlet end of the water outlet connector is connected to a water source, and the outlet ends of the first and second connectors are respectively connected to the first and second water valves. The first water valve includes at least two first outlet ends, which are connected to the ice maker or the water dispenser. The second water valve includes at least two second outlet ends, which are connected to the ice maker or the water dispenser that is not connected to the first outlet end.

[0010] By pre-diverting the water flow through the outlet pipe joint and then independently controlling the two water valves, hierarchical management is achieved. After the outlet pipe joint physically separates the water path into two paths, the first water valve independently controls the ice maker or water dispenser connected to it, and the second water valve independently controls the ice maker or water dispenser connected to it. The water demand of each path does not need to be coordinated across water valves, reducing the complexity of logic control and improving the reliability of the water system.

[0011] By setting the number of water outlets appropriately, ice makers and water dispensers can be flexibly expanded to meet individual needs.

[0012] In some embodiments, the water system further includes a water storage tank, which is located in the refrigerator compartment. The water inlet of the water storage tank is connected to the outlet of the second connector of the water outlet pipe connector, and the water outlet of the water storage tank is connected to the inlet of the second water valve.

[0013] Alternatively, the inlet of the water tank can be connected to a water source, and the outlet of the water tank can be connected to the inlet of the outlet pipe connector.

[0014] By connecting the water storage tank in series between the second outlet end and the second water valve of the outlet pipe connector, the water flow after being diverted by the outlet pipe connector first enters the water storage tank for buffering, achieving precise pre-cooling at the water end, reducing energy consumption and improving user experience.

[0015] By connecting a water storage tank in series between the water source and the inlet end of the outlet pipe, when multiple water outlets are started simultaneously, the water storage tank ensures stable flow at each outlet of the dual water valve, avoiding problems such as insufficient flow causing the ice maker's ice tray to be not filled or the water dispenser's water flow to become thin.

[0016] In some embodiments, the first water valve and the outlet pipe connector are disposed inside the press chamber of the housing, and the first water valve and the outlet pipe connector are integrally formed or integrally assembled.

[0017] By integrating the first water valve and the outlet pipe connector into the press chamber and using one-piece molding or one-piece assembly, the installation efficiency can be effectively improved, the installation difficulty can be reduced, the storage space occupied can be reduced, and the internal utilization rate of the chamber can be increased.

[0018] In some embodiments, the water system further includes a fixing plate and a water pipe diverter. The fixing plate is connected to the side wall of the first water valve and the compressor chamber, respectively. The water pipe diverter is disposed between the first outlet end of the outlet pipe joint and the first water valve, or between the first outlet end of the first water valve and the water valve pipe of the first outlet end.

[0019] The fixing plate, water pipe diverter, first water valve and outlet pipe connector are integrally molded or assembled as a whole.

[0020] By setting a fixing plate to enhance the fixing accuracy of the components, the fixing plate serves as a connecting carrier between the first water valve and the side wall of the compressor chamber, achieving precise positioning of the first water valve during installation and reducing the impact of vibration generated by the compressor operation on the first water valve.

[0021] Pipe deflectors can reduce damage caused by pipe bends and water flow resistance.

[0022] In some embodiments, the enclosure further includes a rear panel, which is disposed opposite to the door.

[0023] The first water valve and the water outlet pipe connector are separate components. The first water valve is located inside the refrigerator compartment, and the water outlet pipe connector is located inside the refrigerator compartment or on the side of the back panel away from the door.

[0024] By separating the first water valve and the outlet pipe connector, the positions of the various components of the water system can be flexibly arranged, reducing the amount of piping required.

[0025] In some embodiments, the first water valve includes two first water outlets, and two ice makers are configured, respectively defined as the first ice maker and the second ice maker. The water system includes an inlet pipe, a first outlet pipe, a first water valve pipe, a second water valve pipe, and a water pipe protective clamp. The inlet pipe is connected to the water source and the inlet end of the outlet pipe connector. The first outlet pipe is connected to the second outlet end of the outlet pipe connector and the second water valve. The first water valve pipe is connected to one of the first outlet ends of the first water valve and the first ice maker. The second water valve pipe is connected to the other first outlet end and the second ice maker. The water pipe protective clamp is used to fix the inlet pipe, the first outlet pipe, the first water valve pipe, and the second water valve pipe to the back panel.

[0026] By setting up water pipe protective clamps to limit the freedom of multiple water pipes, the multiple water pipes can be arranged in an orderly manner to avoid stacking. At the same time, the water pipes are protected to prevent them from touching and scratching the compressor's rear cover or back panel, and to reduce problems such as resonance noise generated by the water pipes when the water system is working.

[0027] In some embodiments, a hinge hole is provided on the door, and a second water valve is provided on the door corresponding to the refrigerator compartment and close to the refrigerator compartment. The water system also includes a door inlet pipe, a second connector outlet end of the door inlet pipe and the outlet pipe connector, and the door inlet pipe passes through the hinge hole and is connected to the second water valve.

[0028] By connecting the water inlet pipe of the door through the hinge hole to the second water valve, the water system can span the two relatively independent modules of the box and the door, thus achieving smooth water supply.

[0029] In some embodiments, the enclosure further includes a rear panel, which is disposed opposite to the door. A water outlet connector is disposed on the side of the rear panel away from the door. The water system includes a fastener disposed on the side of the rear panel away from the door. The fastener is used to install the water outlet connector on the rear panel.

[0030] By setting a fixing component to limit the water outlet pipe joint, the water outlet pipe joint is effectively prevented from warping or loosening, improving the sealing reliability of the water pipe connection. It is also simple and quick to operate, has high production efficiency, and good processability.

[0031] Secondly, embodiments of this application propose a refrigerator, including a cabinet, a compressor compartment, a door, an ice maker assembly, a water dispenser assembly, and a third water valve. The cabinet defines a refrigerator compartment and a freezer compartment. The compressor compartment is located inside the cabinet and at the bottom of the cabinet along its height. The door is rotatably connected to the cabinet to open or close the refrigerator compartment and the freezer compartment. The ice maker assembly includes at least two ice makers installed in the refrigerator compartment or the freezer compartment. The water dispenser assembly includes at least two water dispensers installed in the door or the refrigerator compartment. The third water valve is installed in the compressor compartment or the refrigerator compartment.

[0032] The third water valve includes a third inlet and at least four third outlets. The third inlet is connected to a water source, and the third outlet is connected to an ice maker or a water dispenser.

[0033] By using a technical solution that applies to only one water valve, the investment in water valve component molds is minimized, and the solution is highly versatile. Production and assembly are carried out only for one water valve, resulting in less labor time and higher efficiency.

[0034] In some embodiments, the door body is provided with hinge holes, and the water system further includes:

[0035] Two water inlet pipes are provided for each door, with the inlet ends of the two pipes connected to two third outlet ends respectively. The side of each water inlet pipe away from the third outlet end passes through the hinge hole and connects to the corresponding water dispenser.

[0036] By setting up two gate-type water inlet pipes, the system can adapt to different water usage environments, thereby improving the applicability and expandability of the water system. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0077] Example 1

[0078] This application provides a refrigerator. Based on the teachings of the technical solution of this application, those skilled in the art can adapt the technical solution of this application to other refrigeration equipment, and these applications should all be included within the protection scope of this application.

[0079] The refrigerator provided in this application embodiment can have various implementation methods. For example, it can be a double-door refrigerator, a single-door refrigerator, etc.

[0080] This application provides a refrigerator, as shown in the embodiments below. Figure 1 As shown, the refrigerator includes a cabinet 10. The cabinet 10 includes an outer shell defining a receiving cavity, an inner liner disposed in the receiving cavity, and a heat insulation layer disposed between the inner liner and the outer shell for heat insulation.

[0081] The outer casing includes a back panel 12, which is positioned opposite to the door 20.

[0082] The inner liner is defined to have at least one storage compartment. The inner liner is also defined to have a front opening communicating with the storage compartment for placing food into or removing food from the storage compartment.

[0083] The storage compartment can be set as one, and can be set as either a refrigerator compartment 13 or a freezer compartment.

[0084] The storage room can be configured as two, defined as the first storage room and the second storage room. The first storage room is a cold storage room 13, which is equipped with at least one shelf to divide the first storage room into multiple cold storage spaces. A cold storage drawer is provided in at least one cold storage space to facilitate the user's access to refrigerated items.

[0085] The second storage compartment is configured as a freezer compartment, and at least one shelf is provided in the second storage compartment to divide the second storage compartment into multiple freezer storage spaces. A freezer drawer is provided in at least one freezer storage space for storing frozen items for easy access by the user.

[0086] For example, the second storage chamber is located below the first storage chamber.

[0087] In addition, there are no restrictions on the shape and size of the box 10, and the box 10 can be set as a cuboid box 10.

[0088] Furthermore, the refrigeration modes of a refrigerator include, but are not limited to, direct cooling, air cooling, and hybrid cooling (direct cooling and air cooling). This embodiment mainly uses air cooling as an example. Optionally, the refrigerator is equipped with a refrigeration system and an air duct system. The refrigeration system generates cold air, and the air duct system can transport the cold air generated by the refrigeration system to the freezer compartment and refrigerator compartment 13 of the refrigeration equipment to achieve the purpose of refrigeration in the refrigerator compartment 13 and freezing in the freezer compartment.

[0089] A refrigeration system includes a compressor, condenser, throttling device, evaporator, and fan. The compressor, condenser, throttling device, and evaporator are connected by piping to form a refrigerant circulation loop. The compressor and throttling device are generally located at the bottom of the refrigeration equipment. The refrigeration system executes the refrigeration cycle of the refrigeration equipment by using the compressor, condenser, throttling device, and evaporator. The refrigeration cycle involves a series of processes, including compression, condensation, throttling cooling, and evaporation, to cool the air inside the refrigeration equipment.

[0090] The air duct system includes a refrigerated air duct, which can be installed inside the refrigerated compartment 13 or at a location on the back panel 12 away from the refrigerated compartment 13.

[0091] The refrigerator also includes a compressor compartment 11, which is used to install at least the compressor. The compressor compartment 11 is located inside the cabinet 10 and at the bottom of the cabinet 10 along its length.

[0092] The refrigerator includes a door 20, which can be connected to the cabinet 10. The storage compartment is opened or closed by rotating the door 20. In some embodiments, the door 20 and the cabinet 10 are connected by a hinge.

[0093] The door body 20 includes an inner door liner, a door shell, and a foam layer disposed between the inner door liner and the door shell.

[0094] The refrigerator includes an ice maker assembly. The ice maker assembly produces ice. The ice maker assembly includes at least two ice makers. The ice makers are installed in either the refrigerator compartment 13 or the freezer compartment.

[0095] The refrigerator includes a water dispenser assembly. The water dispenser assembly is used to supply water. The water dispenser assembly includes at least two water dispensers. The water dispensers are installed on the door 20 or inside the refrigerator compartment 13.

[0096] The refrigerator includes a water system for supplying water source 120 to the ice maker assembly and the water dispenser assembly. This water source can be an external source or located in an internal water tank.

[0097] In related technologies, examples are given of two ice makers and two water dispensers. (Refer to...) Figure 2As shown, the water from the water source 120 after being filtered by the filter 6 is distributed through a three-inlet water valve A. One path goes to the first ice maker 101, another path goes to the second ice maker 102, and the third path goes to a two-inlet water valve B for secondary distribution, and then goes to the first water dispenser 103 and the second water dispenser 104 respectively.

[0098] The above-mentioned system uses two water valves, resulting in high water system costs. Furthermore, when the water dispenser needs water, the water flow must pass through valves A and B sequentially, involving the simultaneous opening and closing of both valves. This places high demands on the water system's software control logic and results in low fault tolerance. In addition, valve A supplies water to both the drinking and ice-making ends simultaneously, meaning valve A's operating time is significantly longer than valve B's. This implies that valve A's lifespan in this system is shorter than valve B's, and if valve A fails, the entire water system will cease to function.

[0099] Based on the above, in the refrigerator proposed in this application embodiment, the number of water outlets of the water valves in the water circuit system is the same as the sum of the number of ice makers and water dispensers, and they correspond one-to-one, reducing interference between individual water demand ends.

[0100] Reference Figure 3 As shown, the refrigerator's water system includes a water outlet connector 2. The water outlet connector 2 includes a connector inlet. The connector inlet is connected to a water source 120.

[0101] The water outlet connector 2 includes a first connector outlet end. The first connector outlet end and the connector inlet end are connected.

[0102] The water outlet connector 2 includes a second connector outlet end. The outlet end of the second connector is connected to the inlet section of the connector.

[0103] Water source 120 is branched off by setting water outlet pipe connector 2.

[0104] The water system includes a first water valve 3. The first water valve 3 includes a first water inlet. The first water inlet is connected to the first outlet end of the outlet pipe connector 2.

[0105] The first water valve 3 includes at least two first water outlets, which are connected to an ice maker or a water dispenser.

[0106] The water system includes a second water valve 4. The second water valve 4 includes a second inlet. The second inlet is connected to the second outlet of the outlet pipe connector 2.

[0107] The second water valve 4 includes at least two second water outlets. The second water outlets are connected to an ice maker or water dispenser that is not connected to the first water outlet.

[0108] The number of ice makers and water dispensers is the same as the number of the first and second water outlets, and they are set up in a one-to-one correspondence.

[0109] The above technical solution optimizes the layout of the water system and re-selects and combines components. It replaces the one-in-three-out water valve with a one-in-two-out water valve and a one-in-two-out water pipe connector 2. The cost of the combination is lower than the cost of a single component.

[0110] In the above, the ice maker and water dispenser can achieve independent water supply, avoiding the loss problem caused by the need for two water valves to work at the same time for a single water circuit, thus improving the durability and reliability of the entire water circuit system.

[0111] The ice maker and water dispenser in the technical solutions of this application embodiment can be combined with the water outlet of the first water valve 3 and the second water valve 4 in any way, as long as one water outlet corresponds to one ice maker or water dispenser, and the water dispenser and ice maker correspond to one water outlet.

[0112] Furthermore, the number of water outlets of the first water valve 3 and the second water valve 4 can be adjusted according to the number of ice makers and water dispensers. Of course, when the number of ice makers and water dispensers increases to a certain level, the number of water valves can be increased to ensure the stability of the water supply system.

[0113] It is known that the number of the first water outlet, the second water outlet, the ice maker, and the water dispenser can be increased. The number of the first water outlet and the second water outlet can be different.

[0114] To better illustrate the technical solutions in the embodiments of this application, the following description takes the example of a first water valve 3 including two first water outlets, a second water valve 4 including two second water outlets, and two ice makers and two water dispensers, with the two first water outlets of the first water valve 3 correspondingly connected to two ice makers and the two second water outlets of the second water valve 4 correspondingly connected to two water dispensers.

[0115] The two ice makers are designated as ice maker 101 and ice maker 102. Ice maker 101 is installed in the refrigerator compartment 13, and ice maker 102 is installed in the freezer compartment. The two water dispensers are designated as water dispenser 103 and water dispenser 104. Water dispenser 103 is installed in a recessed position on the door 20, with the recessed position set from the outer surface of the door 20 towards the inward side. Water dispenser 104 is installed on the side of the door 20 closest to the refrigerator compartment 13.

[0116] Reference Figure 3 As shown, the two first water outlets of the first water valve 3 are connected to the first ice maker 101 and the second ice maker 102, respectively, and the two second water outlets of the second water valve 4 are connected to the first water dispenser 103 and the second water dispenser 104, respectively.

[0117] The water source at the ice-making end is regulated by controlling the opening and closing of the first water valve 3, and the water source at the drinking water end is regulated by controlling the opening and closing of the second water valve 4.

[0118] Reference Figure 4 As shown, the water system includes a water storage tank 5. The relative positional relationship between the water storage tank 5 and the second water valve 4 can be flexibly adjusted according to the internal configuration and layout of the refrigerator.

[0119] In some implementations, refer to Figure 7 , Figure 8 As shown, the water storage tank 5 is installed in the cold storage compartment 13. The water inlet of the water storage tank 5 is connected to the second water outlet of the water outlet connector 2, and the water outlet of the water storage tank 5 is connected to the second water inlet of the second water valve 4 or the first water inlet of the first water valve 3.

[0120] In some implementations, the inlet of the water storage tank 5 of the water system is connected to the water source 120, and the outlet of the water storage tank 5 is connected to the inlet of the outlet pipe connector 2.

[0121] Water can be stored in the water storage tank 5 and pre-cooled in advance using the low temperature (about 1-8℃) in the cold storage compartment 13, so that the cooled water can be delivered to the drinking water end or the ice making end, making it convenient for users to drink cold water and speeding up the ice making process.

[0122] When the water source (120) has poor water quality or users have higher health requirements for drinking water, in order to avoid blockage of the water system pipes after long-term use, and to provide users with healthier, more hygienic, and higher-quality products, in some implementation methods, refer to... Figure 4 As shown, the water system includes a filter 6. Water source 120 first flows into the filter 6 through the inlet pipe 71, thus introducing the water source 120 into the water system. After being filtered by the filter 6, the water flows through the outlet pipe of the filter 6 to the inlet end of the outlet pipe connector 2.

[0123] Filter 6 also has a certain pressure reduction and stabilization function, which can protect the components of the water system from the impact of water pressure fluctuations caused by unstable water pressure in the external water supply pipeline, or the water hammer effect when water is suddenly supplied after a water outage.

[0124] The filter 6 can be installed inside or outside the refrigerator, depending on the refrigerator's exterior layout and internal structure requirements.

[0125] It should be noted that in this embodiment, the water storage tank 5 and the filter 6 are not essential, and those skilled in the art can choose them according to their needs.

[0126] The first and second outlet ends of the water outlet pipe connector 2 flow through the water outlet pipe to the first inlet end of the first water valve 3 and the inlet end of the water storage tank 5, respectively, thereby introducing the filtered drinking water into the tank bodies of the first water valve 3 and the water storage tank 5.

[0127] Among them, the two first water outlets of the first water valve 3 flow to the first ice maker 101 and the second ice maker 102 through the first water valve pipe 74 and the second water valve pipe, respectively.

[0128] After the drinking water entering the water storage tank 5 is pre-cooled and cooled inside the tank, it flows through the outlet of the water storage tank 5 to the second water valve 4, thereby directing the pre-cooled drinking water to the drinking water demand end for the convenience of users to collect water.

[0129] The two second water outlets of the second water valve 4 flow to the first water dispenser 103 and the second water dispenser 104 through the third water valve pipe 76 and the fourth water valve pipe 77, respectively.

[0130] The first water valve 3 can be installed inside the refrigerator or inside a compartment, depending on the refrigerator layout. In some embodiments, refer to... Figure 5 , Figure 6 As shown, the first water valve 3 and the water outlet pipe connector 2 are located inside the compressor compartment 11. Placing the first water valve 3 inside the compressor compartment 11 does not occupy the internal storage space of the refrigerator, nor does it affect the interior layout of the cabinet 10. At the same time, it accommodates different types of refrigerators with significantly different interior configurations and layouts, such as French three-door, French four-door, and side-by-side refrigerators, thus improving compatibility.

[0131] In this embodiment, the first water valve 3 is located inside the compressor chamber 11. When the water pipe needs to change direction due to space constraints, a water pipe deflector is included in the water system to prevent the pipe from bending or turning in a confined space, which could lead to problems such as poor water flow or pipe cracking and damage. This deflector guides the water pipe to change direction.

[0132] Reference Figure 5 , Figure 6 As shown, the water pipe diverter is located between the first connector outlet section of the water outlet pipe joint 2 and the first water valve 3, or between the first outlet end and the water valve pipe of the first outlet end.

[0133] The turning angle of the water pipe diverter can be selected according to requirements, as long as it can meet the requirement of changing the water guiding direction. For example, the water pipe diverter includes a first water pipe diverter 83 that can change the turning angle by 90° and a second water pipe diverter 84 that can change the turning angle by 180°.

[0134] It is understood that this is just an example. Other water pipe deflectors with different turning angles can be set. The main purpose is to adjust the direction of the inlet and outlet water pipes of the compressor chamber 11 to be the same.

[0135] Due to the limitations of the water valve structure, the first inlet and first outlet of the first water valve 3 are fixed in orientation, which limits the direction of the water pipe connected to it. The first outlet of the water pipe connector 91 faces the same direction as the first inlet, and the first outlet pipe 72 needs to be rotated 180° to connect the water pipe connector 91 and the first water valve 3. A second water pipe deflector 84 is provided here, with its interior forming a semi-circular arc, thereby achieving a 180° adjustment of the water guiding direction of the first outlet pipe 72.

[0136] The two first water outlets of the first water valve 3 are respectively equipped with a first water pipe diverter 83 and a second diverter. The first water pipe diverter 83 adjusts the direction of the first water valve pipe 74 by 90°, and the second water pipe diverter 84 adjusts the direction of the second water valve pipe 75 by 180°, thereby adjusting the inlet and outlet water pipes of the compressor chamber 11 to the same direction, which facilitates the subsequent clamping and fixing of the water pipe protective clamp 81 to the water pipe.

[0137] Reference Figure 6 As shown, the direction of the third outlet pipe 78 of the water tank 5 after passing through the box 10 is inconsistent with the direction of the door inlet pipe 79, and they are in a cross state. In order to avoid the occurrence of small-angle bends in the water pipe, a water pipe deflector is installed at a suitable position on the third outlet pipe 78 to adjust its direction to be consistent with the door inlet pipe 79, and then it is connected through the water pipe connector 91.

[0138] In some embodiments, the first water valve 3 and the water outlet connector 2 are integrally molded. By integrating the water outlet connector 2 onto the first water valve 3, the integration of components is improved. Here, integral molding refers to the injection molding of the first water valve 3 and the water outlet connector 2 into a single unit.

[0139] In some embodiments, the first water valve 3 and the outlet pipe connector 2 are assembled as a single unit. This single-unit assembly refers to assembling the separate first water valve 3 and outlet pipe connector 2 into a single component before shipment.

[0140] In some implementations, refer to Figure 6 As shown, the water system includes a fixing plate 82. The fixing plate 82 is connected to the first water valve 3 and the side wall of the compressor chamber 11, respectively.

[0141] Since the first water valve 3 will vibrate during operation, in order to improve connection reliability and durability, reduce operating noise, and facilitate maintenance and replacement, it is recommended that the connection points at both ends of the fixing plate 82 be fixed with screws.

[0142] In some embodiments, the fixing plate 82, the first water pipe diverter 83, the first water valve 3, and the outlet pipe connector 2 are integrally formed or assembled as a single unit.

[0143] It should be noted that, in this embodiment, "integrated molding" refers to the injection molding of the fixing plate 82, the first water pipe diverter 83, the first water valve 3, and the water outlet pipe connector 2 into a single unit.

[0144] Integrated assembly refers to assembling the separate fixing plate 82, the first water pipe diverter 83, the first water valve 3, and the outlet pipe connector 2 into a component before leaving the factory.

[0145] In some implementations, refer to Figure 6 As shown, the water system includes an inlet pipe 71, which is connected to the water source 120 and the inlet end of the outlet pipe connector 2.

[0146] The water system includes a first outlet pipe 72, which is connected to the outlet end of the second connector of the outlet pipe connector 2 and the second water valve 4.

[0147] The water system includes a first water valve pipe 74. The first water valve pipe 74 is connected to one of the first water outlets of the first water valve 3 and the first ice maker 101.

[0148] The water system includes a second water valve pipe 75. The second water valve pipe 75 is connected to the other first water outlet of the first water valve 3 and the second ice maker 102.

[0149] Since the first water valve 3 is located inside the compressor compartment 11, before assembling the compressor rear cover, the first water valve pipe 74 and the second water valve pipe 75 corresponding to the first water valve 3, as well as the inlet pipe 71 and the first outlet pipe 72 corresponding to the outlet pipe connector 2, need to be led out from the same place. This is to avoid problems such as messy stacking of water pipes when unrestrained, resonance caused by touching the sharp edge of the compressor rear cover, scratches, damage and leakage.

[0150] The water system also includes a second outlet pipe 73. The second outlet pipe 73 is connected to the outlet end of the first connector of the outlet pipe connector 2 and the first water valve 3.

[0151] In some implementations, refer to Figure 6 As shown, the water system includes a water pipe protective clamp 81, which is used to fix the inlet pipe 71, the first outlet pipe 72, the first water valve pipe 74, and the second water valve pipe 75 to the back plate 12.

[0152] The water pipe protective clamp 81 is used to limit the freedom of multiple water pipes, so that multiple water pipes are arranged in an orderly manner to avoid stacking. At the same time, it protects the water pipes to prevent them from touching and scratching each other with the compressor rear cover or rear panel 12, and reduces problems such as resonance noise generated by the water pipes when the water system is working.

[0153] The water pipe protective clamp 81 is fixed to the back plate 12 with screws to improve the stability of the water pipe protective clamp 81, limit the bending stress generated after multiple water pipes extend from the press chamber 11, and prevent the water pipe protective clamp 81 from loosening during transportation or long-term use.

[0154] To improve production efficiency, in this embodiment, the fixing plate 82, the first water valve 3, the first water pipe diverter 83, the second water pipe diverter 84, the outlet pipe connector 2, the first water valve pipe 74, the second water valve pipe 75, and the first outlet pipe 72 are assembled into a single component. During production line assembly, the inlet pipe 71, the first outlet pipe 72, the first water valve pipe 74, and the second water valve pipe 75, which are connected to the filter 6, are directly plugged into their corresponding load ends. This reduces the potential for mis-installation or omissions of water valves and pipes on the production line, improves process operability, and reduces the likelihood of quality problems.

[0155] The water demand from water source 120 to door 20 needs to cross two relatively independent modules: refrigerator body 10 and door 20. To facilitate water supply, the water system needs to be connected at the junction of body 10 and door 20. In this embodiment, the pipe is run at the door hinge between body 10 and door 20.

[0156] Reference Figure 9 , Figure 10 , Figure 11 As shown, a hinge hole 21 is provided on the door body 20, and the second water valve 4 is provided on the door body 20 (hereinafter referred to as the refrigerator door) corresponding to the refrigerator compartment 13 and is located close to the refrigerator compartment 13.

[0157] The water system includes a door inlet pipe 79. The door inlet pipe 79 is connected to the outlet end of the second connector of the outlet pipe connector 2, and the door inlet pipe 79 passes through the hinge hole 21 and is connected to the second water valve 4. This allows the water source 120 to be transferred from the housing 10 to the door 20, and then introduced to the water demand end of the door 20.

[0158] The second water valve 4 is connected to the water dispenser. In this embodiment, the second water valve 4 is installed on the refrigerator door. For ease of manufacturability, the second water valve 4 is assembled inside the refrigerator. The second water valve 4 is located near the water inlet of the water dispenser.

[0159] The outlet end of the water storage tank 5 is connected to a third outlet pipe 78. After the third outlet pipe 78 passes through the box 10, it is connected to the door inlet pipe 79 through a water pipe connector 91. The door inlet pipe 79 is connected to the second water valve 4, so that drinking water flows to the second inlet end of the second water valve 4.

[0160] Then, the water flows through the third water valve pipe 76 and the fourth water valve pipe 77 at the second outlet of the second water valve 4 to the first water dispenser 103 and the second water dispenser 104, respectively.

[0161] Reference Figure 14 , Figure 15 As shown, in order to fix the second water valve 4 and facilitate operation and assembly, the second water valve 4 is installed on the water valve bracket 41 and fixed by the buckle 851 or limiting rib on the water valve bracket 41.

[0162] To facilitate maintenance and replacement, the second water valve 4 is usually assembled after the door body 20 has been foamed, that is, the second water valve 4 is set after the foaming layer of the door body 20.

[0163] One end of the door inlet pipe 79 is connected to the second water valve 4, and the other end of the door inlet pipe 79 is connected to the third water outlet pipe 78 from the cabinet 10. One end of the third water valve pipe 76 is connected to the second water valve 4, and the other end of the third water valve pipe 76 is connected to the first water dispenser 103. The first water dispenser 103 is installed on the door, and the water outlet of the first water dispenser 103 is located on the side of the door 20 away from the refrigerator compartment 13.

[0164] The water inlet pipe 79 and the third water valve pipe 76 of the door body need to be embedded in the foam layer, and a water pipe box 86 needs to be installed where the water pipes penetrate the foam layer. This is to facilitate the containment of the free-moving water inlet pipe 79 and the third water valve pipe 76 during the foaming of the door body 20, and to prevent the water pipes from swinging freely and affecting the foaming of the door body 20.

[0165] After the door body 20 is foamed, it is convenient to remove the two water pipes from the water pipe box 86 and connect them to the second water valve 4.

[0166] The water pipe box 86 is usually located in the area near the second water valve 4 and is attached to the door liner by a snap-fit ​​structure 851 or double-sided adhesive. The corresponding position of the door liner has an opening to facilitate the connection of the water pipe to the second water valve 4.

[0167] Reference Figure 5 As shown, the water pipes connecting various water circuit components are set on the back panel 12 of the refrigerator. Some water pipes run from the compressor compartment 11 to the top of the cabinet 10. Fixed pipe clamps can be set at appropriate positions to limit the freedom of the water pipes, preventing water pipes from bending and causing poor water flow, or bending or loosening that would affect the packaging and storage of the whole machine.

[0168] In some implementations, multiple inlet and outlet water terminals of the same component are distinguished by color or length to prevent misuse, such as the water pipes inserted into the inlet and outlet water terminals of the second water valve 4, the first water valve 3, the water storage tank 5, and the outlet water pipe connector 2.

[0169] In the above embodiment, only one water pipe passes through the hinge hole 21 of the door body 20. When the water pipe bends, the pressure exerted on the door hinge shaft is small, which hardly affects the flexibility of the door hinge rotation when the user opens and closes the door body 20. The assembly production only requires one corresponding water pipe connector 91, and the process operation is simple.

[0170] This application provides multiple optional solutions while meeting product functional requirements, to adapt to refrigerator products with different product forms, configurations, and interior layouts of the cabinet 10, thereby improving the applicability and versatility of the solutions.

[0171] In this embodiment, the first water valve 3 is located inside the compressor compartment. This method does not occupy the storage space of the refrigerator, has minimal impact on the interior layout of the cabinet 10, and does not affect the adjustment of the internal configuration of the cabinet 10. It has good compatibility with products on different platforms in the same series, and can simultaneously accommodate French three-door, French four-door, and side-by-side refrigerator products with significant differences in interior configuration and layout.

[0172] Example 2

[0173] The difference between this embodiment and Embodiment 1 lies in the location of the first water valve 3.

[0174] In this embodiment, refer to Figure 19 As shown, the first water valve 3 is located inside the refrigerator compartment 13. The first water valve 3 and the water outlet pipe connector 2 are separate units. The first water valve 3 is located around the water storage tank 5 to facilitate pipe routing.

[0175] In this embodiment, the water outlet connector 2 can be located inside the refrigerator compartment, or the water outlet connector 2 can be located on the side of the back panel 12 away from the door 20.

[0176] In some implementations, the outlet pipe connector 2 can be located inside the compressor chamber 11.

[0177] Reference Figure 19 As shown, the first water valve 3 is located inside the refrigerator compartment 13. The first water valve 3 is located in the area behind the refrigerator return air cover, so it does not occupy the storage space of the refrigerator compartment 13.

[0178] After the various components of the water system are assembled, the first water valve 3, the water storage tank 5, and the related water pipes are located below the refrigerated air duct, behind the refrigerated return air cover. This effectively blocks the noise from the first water valve 3 from spreading outward, reducing overall machine noise and improving user experience; it also prevents components from being exposed for extended periods and causing damage, eliminating the potential hazard of current leakage from electronic components injuring users.

[0179] Since the first water valve 3 and related components are located in the cold storage room in this embodiment, the space occupied by them in the cold storage room is significantly larger than that in the technical solution in embodiment 1 (here referring to the space occupied in the height of the cold storage room 13).

[0180] Furthermore, since the layout of the refrigerator compartment 13 is also determined after the assembly plan is finalized, it cannot accommodate French three-door, French four-door, and side-by-side refrigerator products with significant differences in interior configuration and layout. In other words, the plan has poor compatibility.

[0181] The technical solutions in Embodiment 1 and Embodiment 2 each have their own advantages and disadvantages, and can be selected according to needs.

[0182] Example 3

[0183] The difference between this embodiment and embodiment 1 lies in the location of the water outlet connector 2.

[0184] In Example 1, the water outlet pipe connector 2 and the first valve are integrated together. The first water outlet pipe 72 of the water outlet pipe connector 2 needs to be led out from the compressor chamber 11 and then connected to the water inlet of the water storage tank 5 along the water pipe guide groove of the back plate 12. The increase in the length of the water pipe will also increase the cost of the water pipe.

[0185] In this embodiment, refer to Figure 16 , Figure 17 , Figure 18 As shown, the water outlet connector 2 is located on the side of the rear panel 12 away from the door body 20, and the water system also includes a fixing member 85. The fixing member 85 is located on the side of the rear panel 12 away from the door body 20. The fixing member 85 is used to install the water outlet connector 2 on the rear panel 12.

[0186] Optionally, the water outlet connector 2 can be installed in the area of ​​the refrigerator back panel 12 corresponding to the water tank 5.

[0187] Reference Figure 16 As shown, the direction of water source 120 towards the water demand side is similar to... Figure 5 The design is consistent with the previous one, but the difference lies in the simpler layout of the 12 water pipes on the back panel. Under the same conditions, the cost of water system components is lower.

[0188] It should be noted that in this embodiment, a water pipe fixing clamp needs to be installed near the water outlet pipe joint 2 to prevent the water outlet pipe joint 2 from warping / loosening and affecting the insertion and sealing effect of the water pipe and the water outlet pipe joint 2, thus avoiding water leakage.

[0189] In some embodiments, the fastener 85 is configured as a fixing box, see reference. Figure 17 As shown, the water outlet pipe connector 2 is clipped into the fixing box that is pre-embedded inside the foaming layer before foaming. This technical solution directly fixes the water outlet pipe connector 2 through the buckle 851 on the fixing box, which can better prevent the water outlet pipe connector 2 from warping / loosening and improve the sealing reliability of the water pipe connection; and it is simple and quick to operate, has high production efficiency and good processability.

[0190] Example 4

[0191] The difference between this embodiment and Embodiment 1 lies in the water valve settings of the water system.

[0192] Replace the first water valve 3 and the second water valve 4 with the third water valve 110. The third water valve 110 is located in the compressor compartment 11 or the cold storage compartment 13.

[0193] The third water valve 110 includes a third water inlet. The third water inlet is connected to the water source 120.

[0194] The third water valve 110 includes at least four third water outlets, which are connected to an ice maker or a water dispenser. The number of third water outlets is the same as the number of ice makers and water dispensers, and each third water outlet corresponds to one ice maker and one water dispenser.

[0195] Reference Figure 20 As shown, the third water valve 110, which includes four third water outlets, will be used as an example for explanation. The four third water outlets are respectively connected to the first ice maker 101, the second ice maker 102, the first water dispenser 103, and the second water dispenser 104. Each water outlet has independent control, and the control logic is simple.

[0196] In the technical solution of Example 1, the assembly process of installing the first water valve 3 in the press chamber 11 is slightly poor. The operating height of the workers during assembly should be basically level with the position of the refrigerator press chamber 11 on the production line in order to improve the assembly efficiency. When the process of connecting the water pipe to the water valve is involved, a special static operating platform is also required, which places certain requirements on the layout and setting of the production line.

[0197] The water system components in this embodiment have the lowest cost. Furthermore, since only one water valve is used, there is only one assembly location and one assembly design, the investment in related molds for the water valve assembly is minimized, and standardization is improved. Production and assembly only target one water valve, resulting in less time and higher efficiency.

[0198] In some implementations, refer to Figure 12 , Figure 13 As shown, there are two water inlet pipes 79 in the door body. The inlet ends of the two water inlet pipes 79 are connected to the two third water outlets respectively, and the side of the two water inlet pipes 79 away from the third water outlets passes through the hinge hole 21 and is connected to the two water dispensers respectively.

[0199] Since there are two water demand ends on the door body 20 (first water dispenser 103 and second water dispenser 104), based on the refrigerator product design layout, maximizing the utilization of the door body 20, and user convenience, these two functional modules are usually integrated on the same door body 20. Accordingly, two water pipes need to be passed through the hinge hole 21 of the door hinge.

[0200] That is, one of the door body water inlet pipes 79 leads to the first water dispenser 103, and the other door body water inlet pipe 79 leads to the second water dispenser 104, which requires a larger shaft hole diameter.

[0201] When the thickness of the door body 20 is small, the design of the door hinge, the end cap of the door body 20 and the internal assembly structure will be limited. In addition, since two water pipes pass through the hinge hole 21, the pressure exerted on the door hinge shaft when the water pipes are bent is twice that of a single water pipe, which will reduce the flexibility of the door hinge rotation and thus affect the user experience when opening and closing the door.

[0202] In some implementations, the water demand terminals of the door 20 are located on different door 20s. In this case, the water pipes corresponding to the housing 10 and the door 20 are located on different door 20s, that is, a water pipe passes through the hinge hole 21 of each of the two door 20s, which reduces the impact on the door hinge and the door 20. However, this reduces the integration of the module to some extent.

[0203] The refrigerator proposed in this embodiment includes a cabinet 10, a door 20, an ice maker assembly, a water dispenser assembly, and a water system. The cabinet 10 defines a refrigerator compartment 13 and a freezer compartment. The door 20 is rotatably connected to the cabinet 10 to open or close the refrigerator compartment 13 and the freezer compartment. The ice maker assembly includes at least two ice makers installed in the refrigerator compartment 13 or the freezer compartment. The water dispenser assembly includes at least two water dispensers disposed within the door 20 or the refrigerator compartment 13. The water system connects a water source 120 to the ice maker and the water dispenser. The water system includes... The device includes a water outlet connector 2, a first water valve 3, and a second water valve 4. The inlet end of the water outlet connector 2 is connected to the water source 120. The outlet ends of the first and second connectors are respectively connected to the first water valve 3 and the second water valve 4. The first water valve 3 includes at least two first outlet ends, which are connected to an ice maker or a water dispenser. The second water valve 4 includes at least two second outlet ends, which are connected to an ice maker or a water dispenser that is not connected to a first outlet end. The number of ice makers and water dispensers is the same as the number of first and second outlet ends, and they are set up in a one-to-one correspondence.

[0204] The water flow is pre-diverted through the outlet pipe connector 2, and then the two water valves are independently controlled to achieve hierarchical management. After the outlet pipe connector 2 physically separates the water path into two paths, the first water valve 3 independently controls the ice maker or water dispenser connected to it, and the second water valve 4 independently controls the ice maker or water dispenser connected to it. The water demand of each path does not need to be coordinated across water valves, reducing the complexity of logic control and improving the reliability of the water system.

[0205] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
