[0023] The second water supply pipe comprises:

[0024] A cut-off portion, wherein the lowest height of the cut-off portion is higher than or equal to the height of the highest liquid level line of the water tank.

[0025] By adopting the above technical solution, two independent water pumps supply water separately with clear functions, which can ensure smooth and stable water flow and meet the water supply needs of the water dispenser and ice maker; the water valve is eliminated, avoiding the problem of precise synchronization of the water pump and the water valve, simplifying the control process, simplifying the water supply structure, and reducing costs; the second water supply pipe is provided with a shut-off part, and the water in the water tank will not naturally flow into the water inlet of the ice maker in the non-water supply state, ensuring that the second water supply pipe near the water inlet of the ice maker will not freeze due to water accumulation, thereby ensuring the normal operation of the ice maker and improving the functionality and reliability of the refrigerator.

[0026] In some embodiments of the present application, the ice maker is located below the water tank;

[0033] With this arrangement, the shut-off portion is divided into a first part and a second part, ensuring that water must flow upward and then downward when passing through the shut-off portion. When the water supply is stopped, water will not naturally flow into the extension portion due to gravity, preventing water from accumulating in the extension portion and further preventing the water inlet of the ice maker from freezing, thereby ensuring the stability of the water supply and the stability of the ice maker operation.

[0034] In some embodiments of the present application, the ice maker is located above the water tank;

[0102] As described in the background, refrigerators in related art include a cabinet and a door. A water dispenser and ice maker can be installed in the door or cabinet to meet different cooling needs. The refrigerator cabinet also includes a water tank, a water pump, and a water valve connected to a water supply pipe to supply water to the water dispenser and ice maker.

[0103] It's easy to understand that the water supply system consists of a water pump and a water valve. The pump draws water from the water tank and directs it to the water valve, which then distributes the water to the water dispenser or ice maker. These two systems require precise synchronization to ensure smooth water supply. Improper control can cause the pump to idle or continue running even when the valve is closed, resulting in equipment damage or unstable water supply. Furthermore, the water supply system's numerous functional components make it complex, challenging to wire and install, and difficult to maintain.

[0104] Therefore, in order to simplify the water supply structure of the refrigerator and reduce the cost of the water supply structure, the water valve can be eliminated and only the water pump can be installed on the pipes between the water dispenser and the water tank and between the ice maker and the water tank. The water pump can be used to directly extract water from the water tank to supply the water dispenser or ice maker, so as to reduce the complexity of the water supply structure and improve the convenience of installation and maintenance.

[0105] Typically, the water tank is located in the refrigerator compartment, and the ice maker is located in the freezer compartment. For example, in a refrigerator with the refrigerator compartment located above the freezer, the water tank is located above the ice maker. When the ice maker completes water filling according to the programmed procedure, the water pump stops. However, there is no valve between the ice maker and the water tank to prevent water from flowing. The pipes between the two remain connected, and due to the siphon effect, water in the water tank continues to drip until the water level reaches the level at the ice maker's water inlet. Consequently, water is always present in the pipes near the ice maker's water inlet, potentially causing the inlet to freeze, preventing water from filling and rendering the ice maker inoperable.

[0106] In view of this, an embodiment of the present application provides a refrigerator, including a box body, a refrigerator compartment and a freezer compartment are provided on the front side of the box body; a water dispenser is provided in the refrigerator compartment; an ice maker; and a water tank having a maximum liquid level line.

[0107] Compared to the water supply structure in related art, the refrigerator provided in the present embodiment also includes a water pump assembly, comprising a first water pump, a second water pump, and a mounting bracket. The first and second water pumps are fixedly connected to the refrigerator body via the mounting bracket. The water inlet of the first water pump is connected to the water tank, and the water outlet of the first water pump supplies water to the water dispenser via a first water supply pipe. The water inlet of the second water pump is connected to the water tank, and the water outlet of the second water pump supplies water to the ice maker via a second water supply pipe. By having two water pumps supply water to the water dispenser and ice maker, respectively, the functions are clearly defined and the stability of the water supply is improved.

[0108] In order to prevent the water in the second water supply pipe from accumulating at the water inlet of the ice maker, the refrigerator in the embodiment of the present application has a reasonable layout of the second water supply pipe, and a cut-off portion is provided in the second water supply pipe. The lowest height of the cut-off portion is higher than or equal to the height of the highest liquid level line of the water tank. When the water supply is stopped, the cut-off portion can cut off the water flow in the second water supply pipe, and the water flow cannot continue to flow to the water inlet of the ice maker. Moreover, due to the high position of the cut-off portion, the water inside the cut-off portion will flow back to the water tank. This means that there is no water in the pipe near the water inlet of the ice maker, thus solving the problem of the water inlet of the ice maker freezing. It can be seen that the refrigerator in the embodiment of the present application reduces the complexity of the water supply structure, reduces the cost of the water supply structure, and is relatively simple in the control process.

The water inlet of the second water pump 520 is connected to the water tank 400, and the water outlet of the second water pump 520 supplies water to the ice maker 300 through a second water supply pipe 700. The second water pump 520 is responsible for transporting water from the water tank 400 to the ice maker 300, ensuring smooth and stable water flow to meet the water supply needs of the ice maker 300.

[0138] The water pump assembly 500 includes a mounting bracket 530. The first water pump 510 and the second water pump 520 are fixedly connected to the housing 100 via the mounting bracket 530. The mounting bracket 530 integrates the first and second water pumps 510, 520, improving the integration of the water pump assembly 500 and facilitating installation and maintenance. The mounting bracket 530 secures the water pumps to the housing 100, ensuring their stability and reducing vibration and noise.

[0139] For example, the first water pump 510 or the second water pump 520 may be a DC weak-current water pump, which has high safety and low manufacturing cost, thereby reducing the cost of the water supply structure.

[0140] The water supply pipe 700 includes a shut-off portion 710. This is designed to prevent water from accumulating at the water inlet of the water dispenser. The minimum height of the shut-off portion 710 is equal to or higher than the maximum liquid level 401 of the water tank 400. When the water supply is not in operation, water in the water tank 400 will not naturally flow into the water inlet of the water dispenser. This prevents water from permanently accumulating in the pipe at the water inlet, preventing freezing or leakage.

[0141] When the water pump stops supplying water to the water-using device, the shut-off portion 710 can cut off the water flow in the water supply pipe to prevent water from accumulating in the portion of the water supply pipe between the shut-off portion 710 and the water-using device.

[0142] However, water may still remain in the portion of the water supply pipe between the shut-off portion 710 and the water tank 400. A water pump can pump the water in the water supply pipe back into the water tank. The water in the portion of the water supply pipe between the shut-off portion 710 and the water tank 400 can be transferred back to the water tank 400 to clear the water in the water supply pipe and prevent it from freezing.

[0143] The refrigerator of the embodiment of the present application eliminates the water valve, avoiding the problem of precise synchronization of the water pump and the water valve, simplifying the control process, simplifying the water supply structure, and reducing costs; and the arrangement of the first water supply pipe 600 and the second water supply pipe 700 is rationally arranged, which can solve problems such as freezing and blockage of the water injection port of the ice maker 300 or leakage of the water injection port of the water dispenser 200, thereby ensuring the stability of the water supply and the stability of the operation of the ice maker 300 and the water dispenser 200.

[0144] Reference Figure 6-Figure 7 In some possible implementations, the mounting bracket 530 may be provided with a first overlapping portion 531. Fixing the first water pump 510 by the first overlapping portion 531 can reduce vibration and noise, ensure that the first water pump 510 remains stable during operation, and improve the stability and reliability of the water supply system.

[0145] There may be two first overlapping portions 531 , and the water inlet and outlet of the first water pump 510 are overlapped on the two first overlapping portions 531 , respectively, to improve the stability of the first water pump 510 .

[0146] The water inlet and outlet of the first water pump 510 can both be provided with a first hose 511. The first hose 511 can seal the water inlet and outlet pipe joints of the first water pump 510. The first hose 511 is correspondingly overlapped on the first overlap portion 531. The first hose 511 connected at both ends of the first water pump 510 is installed on the first overlap portion 531 in a hanging manner. Therefore, the vibration of the first water pump 510 is first transmitted to the first hose 511. Since the first hose 511 is made of a soft material, it can effectively absorb vibration energy and reduce noise.

[0147] A first limiting groove 5311 may be provided on the first overlapping portion 531. The first limiting groove 5311 is used to accommodate the first rubber tube 511 so as to stabilize the position of the first rubber tube 511.

[0148] A first limiting member 512 may be provided on the first rubber hose 511. The first limiting member 512 may be engaged in the first limiting groove 5311 to limit the displacement of the first rubber hose 511 under the vibration of the first water pump 510.

[0149] For example, the first limiting member 512 may be in a square shape. The square first limiting member 512 can limit the first hose 511 from twisting in the first limiting groove 5311 to ensure smooth water flow.

[0150] The mounting bracket 530 may be provided with a second overlapping portion 532 , and the second water pump 520 is fixed to the second overlapping portion 532 , which can reduce vibration and noise, ensure that the second water pump 520 remains stable during operation, and improve the stability and reliability of the water supply system.

[0151] There may be two second overlapping portions 532 , and the water inlet and outlet of the second water pump 520 are overlapped on the two second overlapping portions 532 respectively, so as to improve the stability of the second water pump 520 .

[0152] The water inlet and outlet of the second water pump 520 can both be provided with a second hose 521. The second hose 521 can seal the pipe joints at the water inlet and outlet of the second water pump 520. The second hose 521 is overlapped on the second overlap portion 532. The second hose 521 connected at both ends of the second water pump 520 is mounted on the second overlap portion 532 in a hanging manner. Vibration of the second water pump 520 is first transmitted to the second hose 521. Since the second hose 521 is made of a soft material, it can effectively absorb vibration energy and reduce noise.

[0153] A second limiting groove 5321 may be provided on the second overlapping portion 532. The second limiting groove 5321 is used to accommodate the second rubber tube 521 so as to stabilize the position of the second rubber tube 521.

[0154] A second limiting member 522 may be provided on the second rubber hose 521 . The second limiting member 522 may be engaged in the second limiting groove 5321 to limit the displacement of the second rubber hose 521 under the vibration of the second water pump 520 .

[0155] For example, the second limiting member 522 may be in a square shape. The square second limiting member 522 can limit the second rubber hose 521 from twisting in the second limiting groove 5321 to ensure smooth water flow.

[0156] For example, a retaining bar can be provided on the mounting bracket 530. A retaining groove can be provided on the inner wall of the housing 100. By inserting the retaining bar into the retaining groove, the mounting bracket 530 can be positioned to prevent the mounting bracket 530 from becoming loose when the first water pump 510 and the second water pump 520 are subsequently installed.

[0157] For example, fasteners can be used to fix the mounting bracket 530 to the housing 100. The fasteners can be screws, which have a stable connection structure and can improve the assembly stability and reliability of the water pump assembly 500. The installation method is simple and easy to disassemble, which can facilitate the installation and maintenance of the water pump assembly 500.

[0158] It can be understood that the mounting bracket 530 integrates the first water pump 510 and the second water pump 520 together, making the installation and removal of the water pumps more convenient, facilitating daily maintenance and overhaul, and improving the reliability and convenience of the system.

[0159] For example, the structure of the mounting bracket 530 can be designed based on the actual installation environment inside the refrigerator so that the mounting bracket 530 can be easily installed in the cabinet 100. The first overlapping portion 531 and the second overlapping portion 532 can be designed based on the specifications and dimensions of the first water pump 510 and the second water pump 520 to improve adaptability and enable the first water pump 510 and the second water pump 520 to be stably installed on the mounting bracket 530.

[0160] Reference Figure 4-Figure 5 In some possible embodiments, the refrigerator may be provided with an air duct structure 140. The air duct structure 140 may form an air duct with the housing 100 to optimize the flow path of the cold air and ensure smooth flow of the cold air. The air duct may discharge air to the refrigerating chamber 110. The air duct may evenly transport the cold air to the refrigerating chamber 110, thereby improving the refrigeration effect of the refrigerating chamber 110. The air duct may be connected to the ventilation structure of the shelf 160. This allows the cold air in the air duct to circulate evenly in the refrigerating chamber 110. The air duct may discharge air to the freezing chamber 120, thereby evenly transporting the cold air to the freezing chamber 120, thereby improving the freezing effect of the freezing chamber 120.

[0161] The refrigerator can be equipped with a return air cover 150. When the water pump assembly 500 is installed in the refrigerator body 100, it is located in the area behind the return air cover 150. This not only effectively blocks the outward spread of water pump operating noise, reducing overall noise and improving the user experience, but also conceals the water pump assembly 500 within the refrigerator compartment 110, preventing damage from prolonged exposure and minimizing potential harm to the user from current leakage from electronic components. Furthermore, the water pump assembly 500 cannot be directly observed by the user during normal use of the refrigerator, improving the aesthetics.

[0162] The return air cover 150 may have a first surface. The first surface faces the front side of the housing 100. When the user uses the refrigerator normally, the first surface of the return air cover 150 can be directly observed, thereby improving the neatness and aesthetics of the interior of the refrigerator. The return air cover 150 may have a second surface. The second surface faces the rear side of the housing 100. The second surface is opposite to the water pump assembly 500 and can provide protection for the water pump assembly 500. The second surface of the return air cover 150 and the housing 100 form an accommodating space 800. The accommodating space 800 can accommodate the water pump assembly 500 to prevent the water pump assembly 500 from occupying the space inside the refrigerator for storing food.

[0163] The return air cover 150 is movably mounted on the air duct structure 140. The return air cover 150 can centrally manage and protect the water pump assembly 500. When the water pump assembly 500 needs to be maintained, the return air cover 150 only needs to be removed to expose the water pump assembly 500 in the accommodating space 800, which is convenient for maintenance and inspection.

[0164] For example, the return air cover 150 can be connected to the duct structure 140 using fasteners. These fasteners can be screws. The screw connection structure is stable, improving the stability of the return air cover 150. Furthermore, the screw installation method is simple and easy to remove, facilitating the installation and removal of the return air cover 150.

[0165] The following describes the configuration and use of the shut-off portion 710 by taking the second water supply pipe 700 provided with the shut-off portion 710 as an example.

[0166] Reference Figure 14-15 It can be understood that in the prior art, the refrigerating chamber 110 of a refrigerator product is usually located above the freezing chamber 120 , and the water tank 400 is arranged in the refrigerating chamber 110 .

[0167] Among them, the water dispenser 200 can be set on the refrigeration door 131. At this time, the height of the water inlet of the water dispenser 200 is lower than the highest liquid level line 401 of the water tank 400. In order to prevent water from accumulating at the water inlet, a water valve can be set on the first water supply pipe 600 to cut off the water flow in the first water supply pipe 600 to prevent water from accumulating at the water inlet of the water dispenser 200.

[0168] The ice maker 300 is arranged in the freezer compartment 120. At this time, the height of the water inlet of the ice maker 300 is lower than the highest liquid level line 401 of the water tank 400. In order to prevent water from accumulating at the water inlet, a water valve can be provided on the second water supply pipe 700 to cut off the water flow in the second water supply pipe 700 to prevent water from accumulating at the water inlet of the ice maker 300.

[0169] Reference Figure 8 To simplify the refrigerator's water supply structure, water valves can be eliminated. However, there are no water valves between the ice maker 300 and the water tank 400, or between the water dispenser 200 and the water tank 400. The pipes between the ice maker 300 and the water tank 400, and between the water dispenser 200 and the water tank 400, remain connected. Due to the siphon effect, water in the water tank 400 will continue to drip until the water level in the water tank 400 reaches the same level as the water level near the water inlets of the ice maker 300 and the water dispenser 200. As a result, water is always present in the pipes near the water inlets of the ice maker 300 and the water dispenser 200, which could cause the water inlet of the ice maker 300 to freeze, preventing water from being injected and causing the ice-making function to fail. It could also cause water leakage from the water inlet of the water dispenser 200.

[0170] Reference Figure 9 In some possible implementations, the ice maker 300 can be located below the water tank 400. Gravity can be used to make it easier for water to flow to the ice maker 300, reducing the burden on the water pump and improving water supply efficiency.

[0171] The second water supply pipe 700 may include a drainage portion 720. The drainage portion 720 can transport water from the housing 100 to the shut-off portion 710, ensuring smooth water flow. The second water supply pipe 700 may also include an extension portion 730. The extension portion 730 can transport water from the shut-off portion 710 to the water inlet of the ice maker 300, ensuring smooth water flow. For example, the drainage portion 720, the shut-off portion 710, and the extension portion 730 may be integrally formed by bending the pipe, reducing assembly complexity.

[0172] The drainage portion 720 has a first end. This first end is the starting point of the water flow in the drainage portion 720 and is connected to the water tank 400. It can guide the water in the water tank 400 so that the water flows smoothly into the drainage portion 720. The drainage portion 720 has a second end. This second end is the end point of the water flow in the drainage portion 720 and is connected to the shut-off portion 710. It can guide the water to the shut-off portion 710.

[0173] The second end of the drainage section 720 is at a height higher than or equal to the highest liquid level 401 of the water tank 400. This ensures that when the water supply is shut off, the water in the water tank 400 naturally does not flow into the shut-off section 710. A second water pump 520 is provided in the drainage section 720 to efficiently pump water from the water tank 400 and deliver it to the shut-off section 710.

[0174] The extension portion 730 has a first end. This first end is the starting point of the water flow in the extension portion 730 and is connected to the cut-off portion 710. It can divert the water in the cut-off portion 710 so that the water flows smoothly into the extension portion 730. The extension portion 730 has a second end. This second end is the end point of the water flow in the extension portion 730 and is connected to the ice maker 300. It can divert the water to the water inlet of the ice maker 300.

[0175] The height of the first end of the extension portion 730 is higher than or equal to the height of the highest liquid level line 401 of the water tank 400. This ensures that when the water supply is stopped, the water in the water tank 400 will not flow into the cut-off portion 710 under a natural state.

[0176] It can be understood that when the refrigerator of the embodiment of the present application supplies water to the ice maker 300, the water in the second water supply pipe 700 flows along Figure 9 The direction indicated by the arrow in the middle indicates water flow from the water tank 400 to the ice maker 300. The refrigerator of the embodiment of the present application rationally arranges the positions of the drainage portion 720, the shut-off portion 710, and the extension portion 730 of the second water supply pipe 700 in consideration of the relative positions of the water tank 400 and the ice maker 300. This ensures that when the water supply is stopped, water will not flow through the shut-off portion 710 into the extension portion 730 connected to the water inlet of the ice maker 300 due to gravity. This prevents the water inlet of the ice maker 300 from freezing and blocking, thereby ensuring stable water supply and stable operation of the ice maker 300.

[0177] Reference Figure 9 In some possible embodiments, the shut-off portion 710 includes a first portion 711. The first end of the first portion 711 communicates with the second end of the drainage portion 720, connecting the drainage portion 720 and ensuring smooth water flow. The second end of the first portion 711 extends upward. When water enters the shut-off portion 710 from the drainage portion 720, it must first flow upward. This effectively prevents water in the water tank 400 from flowing naturally into the shut-off portion 710 through gravity in the absence of a water pump.

[0178] The shut-off portion 710 includes a second portion 712. The first end of the second portion 712 is connected to the second end of the first portion 711. The second end of the second portion 712 extends downward. When water passes through the shut-off portion 710, it must first flow upward and then downward. This ensures that when the water supply is shut off, gravity prevents water from flowing over the shut-off portion 710 and reaching the water inlet of the ice maker 300. The second end of the second portion 712 is connected to the extension portion 730, ensuring smooth water flow.

[0179] Reference Figure 10-12 In other possible implementations, the ice maker 300 can be located above the water tank 400. Since the height of the ice maker 300 is higher than that of the water tank 400, the water in the second water supply pipe 700 will automatically fall back into the water tank 400 after filling, thus solving the problem of freezing caused by water in the second water supply pipe 700.

[0180] The second water supply pipe 700 includes a drainage portion 720. The drainage portion 720 can transport water from the housing 100 to the cut-off portion 710 to ensure smooth water flow.

[0181] The drainage portion 720 has a first end. This first end is the starting point of the water flow in the drainage portion 720 and is connected to the water tank 400. It can guide the water in the water tank 400 so that the water flows smoothly into the drainage portion 720. The drainage portion 720 has a second end. This second end is the end point of the water flow in the drainage portion 720 and is connected to the shut-off portion 710. It can guide the water to the shut-off portion 710.

[0182] The second end of the drainage section 720 is at a height higher than or equal to the highest liquid level 401 of the water tank 400. This ensures that when the water supply is shut off, the water in the water tank 400 naturally does not flow into the shut-off section 710. A second water pump 520 is provided in the drainage section 720 to efficiently pump water from the water tank 400 and deliver it to the shut-off section 710.

[0183] The shut-off portion 710 extends upward at one end away from the drainage portion 720. When water enters the shut-off portion 710 from the drainage portion 720, it must flow upward. This effectively prevents water in the water tank 400 from flowing naturally into the shut-off portion 710 by gravity when no water pump is operating. This also ensures that when the water supply is stopped, water will not flow over the shut-off portion 710 by gravity and reach the water inlet of the ice maker 300.

[0184] One end of the shut-off portion 710 away from the drainage portion 720 is communicated with the ice maker 300 and can guide water to the water inlet of the ice maker 300 .

[0185] It can be understood that the refrigerator in the embodiment of the present application combines the relative positions of the water tank 400 and the ice maker 300 to rationally arrange the positions of the drainage portion 720 and the shut-off portion 710 of the second water supply pipe 700, ensuring that when the water supply is stopped, water will not flow into the water inlet of the ice maker 300 through the shut-off portion 710 due to gravity, which can solve the problem of freezing and blockage of the water inlet of the ice maker 300, and ensure the stability of the water supply and the stability of the operation of the ice maker 300.

[0186] Reference Figure 10 In some possible implementations, the refrigerator compartment 110 may be disposed above the freezer compartment 120. Placing the refrigerator compartment 110 above the freezer compartment 120 facilitates users in accessing refrigerated food they need daily, as the refrigerator compartment 110 is typically used more frequently than the freezer compartment 120. This layout conforms to ergonomic design, reduces the frequency of users bending over to retrieve items, and improves convenience and comfort.

[0187] The water tank 400 can be located within the refrigerator compartment 110 to take advantage of the cold environment of the refrigerator compartment 110 to keep the water cool, reduce water temperature fluctuations, and ensure a stable water supply. The water pump assembly 500 can also be located within the refrigerator compartment 110 to utilize the space and temperature environment of the refrigerator compartment 110, reduce the workload of the water pump, and facilitate maintenance and repair. The ice maker 300 can also be located within the refrigerator compartment 110 to facilitate user access to ice cubes.

[0188] In some possible embodiments, the water tank 400, the water pump assembly 500 and the ice maker 300 are all arranged in the refrigeration chamber 110, which optimizes the utilization of the internal space of the refrigerator, reduces the difficulty of arranging the second water supply pipe 700, reduces the complexity of the water supply structure, and facilitates maintenance and inspection.

[0189] It can be understood that when the refrigerator of the embodiment of the present application supplies water to the ice maker 300, the water in the second water supply pipe 700 flows along Figure 10The direction indicated by the middle arrow is from the water tank 400 to the ice maker 300. The refrigerator of the present embodiment of the present application rationally arranges the positions of the drainage portion 720 and the shut-off portion 710 of the second water supply pipe 700 in consideration of the relative positions of the water tank 400 and the ice maker 300. This ensures that when the water supply is stopped, water will not flow through the shut-off portion 710 into the water inlet of the ice maker 300 due to gravity. This solves the problem of freezing and clogging of the water inlet of the ice maker 300, ensuring stable water supply and stable operation of the ice maker 300.

[0190] Reference Figure 11 In other possible embodiments, the refrigerator compartment 110 may be located below the freezer compartment 120. Placing the refrigerator compartment 110 below the freezer compartment 120 makes it more convenient for users to access frozen food, as the freezer compartment 120 is typically used less frequently than the refrigerator compartment 110. This layout is consistent with the usage habits of users who frequently access frozen food.

[0191] The ice maker 300 may be disposed in the freezing chamber 120 to utilize the low temperature environment of the refrigerating chamber 110 to improve ice making efficiency.

[0192] A water storage space 121 may be provided in the freezer compartment 120. The water storage space 121 is used to provide a positive temperature environment for accommodating the water pump assembly 500 and the water tank 400, thereby preventing the water in the water pump assembly 500 and the water tank 400 from freezing. The water tank 400 may be provided in the water storage space 121 to utilize the low temperature environment of the water storage space 121 to maintain the low temperature state of the water, reduce water temperature fluctuations, and ensure the stability of the water supply. The water pump assembly 500 may be provided in the water storage space 121 to utilize the space and temperature environment of the water storage space 121, reduce the workload of the water pump, and facilitate maintenance and overhaul. The water storage space 121 can centrally manage and protect the water pump assembly 500 and the water tank 400, facilitate installation and maintenance, and improve the reliability and convenience of the refrigerator.

[0193] The first water supply pipe 600 extends through the water storage space 121 and the inner wall of the housing 100 to the water dispenser 200. The first water supply pipe 600 is not exposed to the environment inside the freezer compartment 120, preventing the low temperatures within the freezer compartment 120 from freezing the water in the first water supply pipe 600, thereby ensuring stable water supply to the water dispenser 200. The second water supply pipe 700 extends through the water storage space 121 and the inner wall of the housing 100 to the ice maker 300. The second water supply pipe 700 is not exposed to the environment inside the freezer compartment 120, preventing the low temperatures within the freezer compartment 120 from freezing the water in the second water pipe, thereby ensuring stable water supply to the ice maker 300. The arrangement of the first and second water supply pipes 600 and 700 within the water storage space 121 and the inner wall of the housing 100 reduces exposure to the water supply pipes, protects the pipes from external environmental influences, ensures stable and hygienic water supply, and helps optimize space utilization within the refrigerator.

[0194] It can be understood that when the refrigerator of the embodiment of the present application supplies water to the ice maker 300, the water in the second water supply pipe 700 flows along Figure 11 The direction indicated by the middle arrow is from the water tank 400 to the ice maker 300. The refrigerator of the present embodiment of the present application rationally arranges the positions of the drainage portion 720 and the shut-off portion 710 of the second water supply pipe 700 in consideration of the relative positions of the water tank 400 and the ice maker 300. This ensures that when the water supply is stopped, water will not flow through the shut-off portion 710 into the water inlet of the ice maker 300 due to gravity. This solves the problem of freezing and clogging of the water inlet of the ice maker 300, ensuring stable water supply and stable operation of the ice maker 300.

[0195] Reference Figure 12 In other possible embodiments, the refrigerator compartment 110 may be located below the freezer compartment 120. Placing the refrigerator compartment 110 below the freezer compartment 120 makes it more convenient for users to access frozen food, as the freezer compartment 120 is typically used less frequently than the refrigerator compartment 110. This layout is consistent with the usage habits of users who frequently access frozen food.

[0196] The ice maker 300 may be disposed in the freezing chamber 120 to utilize the low temperature environment of the refrigerating chamber 110 to improve ice making efficiency.

[0197] The water tank 400 can be located within the cold storage compartment 110, leveraging the cold environment of the cold storage compartment 110 to maintain the water's low temperature, reduce water temperature fluctuations, and ensure a stable water supply. The water pump assembly 500 can also be located within the cold storage compartment 110, utilizing the space and temperature environment of the cold storage compartment 110, reducing the workload of the water pump and facilitating maintenance and repair. The temperature within the cold storage compartment 110 is above zero degrees Celsius, preventing the water in the water tank 400 and the water pump assembly 500 from freezing, thus ensuring a stable water supply.

[0198] The second water supply pipe 700 extends through the inner wall of the refrigerator compartment 110 and the refrigerator body 100 to the ice maker 300. The first water supply pipe 600 is not exposed to the interior space of the refrigerator compartment 110, which can reduce the exposure of the water supply pipe, protect the pipe from external environmental influences, ensure the stability and sanitation of the water supply, and also help optimize the space utilization inside the refrigerator.

[0199] It can be understood that when the refrigerator of the embodiment of the present application supplies water to the ice maker 300, the water in the second water supply pipe 700 flows along Figure 12The direction indicated by the middle arrow is from the water tank 400 to the ice maker 300. The refrigerator of the present embodiment of the present application rationally arranges the positions of the drainage portion 720 and the shut-off portion 710 of the second water supply pipe 700 in consideration of the relative positions of the water tank 400 and the ice maker 300. This ensures that when the water supply is stopped, water will not flow through the shut-off portion 710 into the water inlet of the ice maker 300 due to gravity. This solves the problem of freezing and clogging of the water inlet of the ice maker 300, ensuring stable water supply and stable operation of the ice maker 300.

[0200] In some possible implementations, the water dispenser 200 can be located within the refrigerator door 131. This avoids occupying storage space within the refrigerator compartment 110, thereby improving storage efficiency within the refrigerator and leaving more space for food. The water dispenser 200's water outlet can be located outside the refrigerator door 131. This allows users to directly access cold or iced water without opening the refrigerator door, reducing cold air loss, helping to maintain a stable temperature within the refrigerator, and improving convenience.

[0201] The water dispenser 200 can be arranged in the refrigerator compartment 110. It is more tightly integrated with other functional modules of the refrigerator (such as the ice maker 300, the filtration system, etc.), simplifying the design and installation process. The low temperature environment in the refrigerator compartment 110 also helps to keep the drinking water at a low temperature.

[0202] It can be understood that after the water valve is eliminated from the water supply structure of the refrigerator, the first water pump 510 is directly installed on the pipe between the water dispenser 200 and the water tank 400. The water pump directly draws water from the water tank 400 to supply the water dispenser 200, reducing the complexity of the water supply structure.

[0203] When the water dispenser 200 is installed lower than the water tank 400, after the water supply is stopped, the first water supply pipe 600 between the water dispenser 200 and the water tank 400 remains connected, and the water in the water tank 400 will continue to drip until the water level in the water tank 400 reaches the same level as the water level at the water inlet of the water dispenser 200. The constant presence of water at the water inlet of the water dispenser 200 may cause water leakage.

[0204] It is easy to understand that the first water supply pipe 600 can also be provided with a shut-off portion 710. The specific setting method and usage process can refer to the second water supply pipe 700 above.

[0205] For example, the first water supply pipe 600 may include a shutoff portion 710. Figures 9-13The lowest height of the shut-off portion 710 of the first water supply pipe 600 is higher than or equal to the highest liquid level 401 of the water tank 400. Since the lowest height of the shut-off portion 710 is higher than or equal to the highest liquid level 401 of the water tank 400, when no water is being supplied, water in the water tank 400 will not naturally flow into the water inlet of the water dispenser 200. This prevents water from always being present in the first water supply pipe 600 near the water inlet of the water dispenser 200, thus preventing water leakage.

[0206] The first water supply pipe 600 may include a drainage portion 720. The drainage portion 720 can transport water from the tank 100 to the shut-off portion 710, ensuring smooth water flow. The drainage portion 720 of the first water supply pipe 600 has a first end. The first end is the starting point of the water flow in the drainage portion 720. It is connected to the water tank 400 and can divert water from the water tank 400 into the drainage portion 720. The drainage portion 720 of the first water supply pipe 600 has a second end. The second end is the end point of the water flow in the drainage portion 720. It is connected to the shut-off portion 710 and can divert water to the shut-off portion 710. The second end of the drainage portion 720 is located at a height higher than or equal to the highest liquid level 401 of the water tank 400, ensuring that when the water supply is stopped, the water in the water tank 400 will not naturally flow into the shut-off portion 710. The first water pump 510 is disposed at the drainage portion 720 to effectively pump water from the water tank 400 and deliver the water to the shut-off portion 710 .

[0207] The end of the shut-off portion 710 facing away from the drainage portion 720 extends upward. When water enters the shut-off portion 710 from the drainage portion 720, it must flow upward. This effectively prevents water in the water tank 400 from flowing naturally into the shut-off portion 710 due to gravity when no water pump is working. This ensures that when the water supply is stopped, water will not flow over the shut-off portion 710 due to gravity and reach the water inlet of the water dispenser 200. The end of the shut-off portion 710 facing away from the drainage portion 720 is connected to the water dispenser 200, directing water to the water inlet of the water dispenser 200.

[0208] It can be understood that the positions of the drainage portion 720 and the shut-off portion 710 of the first water supply pipe 600 of the refrigerator in the embodiment of the present application are rationally arranged to ensure that when the water supply is stopped, water will not flow through the shut-off portion 710 into the water inlet of the water dispenser 200 under the action of gravity, thereby reducing the possibility of water leakage at the water inlet of the water dispenser 200.

[0209] The embodiment of the present application provides a refrigerator, including a housing 100. The housing 100 can accommodate and protect internal components of the refrigerator.

[0210] A refrigeration chamber 110 may be provided on the front side of the box body 100. The refrigeration chamber 110 is used to store food that requires a lower temperature but does not need to be frozen.

[0211] A freezing chamber 120 may be provided on the front side of the housing 100. The freezing chamber 120 is used to store food that needs to be frozen and preserved.

[0212] The refrigerator provided in the embodiment of the present application may include a water-using device.

[0213] The refrigerator provided in the embodiment of the present application may include a water tank 400. The water tank 400 can be used to store water used by the water supply device, so as to supply water to the water supply device in time when the water supply device is short of water.

[0214] The water tank 400 can be placed inside the refrigerator compartment 110. This allows the cold temperature of the refrigerator compartment 110 to be fully utilized, keeping the water at a lower temperature and providing cooler drinking water. The water tank 400 can also be placed on the shelf 160. The water tank 400 is easily accessible to the user, allowing for easy removal for cleaning and maintenance.

[0215] The water tank 400 has a maximum liquid level line 401. The maximum liquid level line 401 is used to indicate the maximum storage amount of water in the water tank 400 to prevent the water tank 400 from being overfilled and overflowing.

[0216] The refrigerator provided in the embodiment of the present application includes a water pump assembly 500 .

[0217] The water pump assembly 500 may include a water pump, the water inlet of the water pump being in communication with the water tank 400, and the water outlet of the water pump supplying water to the water-using device through a water supply pipe.

[0218] The water pump assembly 500 may include a mounting bracket 530 , which is disposed on the housing 100 to provide a mounting space for the water pump.

[0219] The water pump assembly 500 may include a water pump connected to the mounting bracket 530 ; the water inlet of the water pump is connected to the water tank 400 , and the water outlet of the water pump supplies water to the water-using device through the water supply pipe; the water pump can at least be reused to pump water in the water supply pipe back to the water tank 400 .

[0220] When the water pump is in operation, it draws water from the water tank 400 and supplies it to water-using devices through the water supply pipe. When the water pump is not in operation, the shut-off portion 710 of the water supply pipe cuts off the water flow in the water supply pipe, and the liquid level in the water supply pipe is lower than or equal to the maximum liquid level line 401 of the water tank 400. The water pump can pump water back into the water tank to transfer the water in the water supply pipe between the shut-off portion 710 and the water tank 400 back to the water tank 400, thereby clearing the water in the water supply pipe and preventing the water supply pipe from freezing and clogging.
