Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to a refrigerator with a water dispenser. Background Art

[0002] Existing refrigerator water dispensers are primarily designed to be placed on the refrigerator door. Inside the door, a water storage box is typically installed, capable of storing a certain amount of water. A dispenser component, which controls water flow, is connected to the door's lower end. This dispenser component extends through a hole inside the door and outward. A mounting box is located outside the door, and a pressure lever is installed below the dispenser component on the door's exterior. To dispense water, the user presses the lever with a container such as a cup.

[0003] However, water dispensers can usually only dispense water at a specific temperature, that is, ice water at the same temperature as the refrigerator. However, many times users want to get room temperature water or hot water, but there are very few refrigerators on the market equipped with temperature-adjustable water dispensers, which greatly affects the user experience.

[0004] Therefore, the existing technology is in urgent need of improvement. Summary of the Invention

[0005] The embodiments of the present invention provide a water dispenser assembly in a refrigerator body and a refrigerator, which can reduce the volume of the water dispenser, thereby ensuring the heat preservation performance of the refrigerator.

[0006] The present invention proposes a water dispenser assembly in a refrigerator body and a refrigerator, comprising a refrigerator compartment; at least one refrigerator compartment door for opening and closing the refrigerator compartment; a water dispenser component configured to supply water and mounted on the refrigerator compartment door; in this technical solution, the water dispenser component comprises a water storage component, a water outlet component, a temperature control screen, and a main control board; the water storage component comprises a water storage box arranged on one side of the refrigerator compartment door; an air duct plate, the outside of which is connected to a main body supply pipe, one end of the main body supply pipe is provided with a main body supply pipe air outlet and a baffle; the water storage box has a door supply pipe air inlet and a door supply pipe on the side close to the refrigerator compartment, and when the refrigerator compartment door is closed, the door supply pipe air inlet corresponds to the main body supply pipe air outlet, and the baffle can cool the water storage box by adjusting the switch state.

[0007] In this technical solution, one end of the main supply pipe is connected to the air outlet of the air duct cover, pre-buried in the foam layer on one side of the box body, and extends to the front of the box body.

[0008] In this technical solution, the other end of the main body supply pipe is the main body supply pipe air outlet, and the main body supply pipe air outlet is close to the refrigerator compartment door.

[0009] In this technical solution, a baffle is installed in the air outlet of the main supply pipe. When the water tank needs to be cooled, the baffle opens to allow cold air to flow into the air inlet of the door supply pipe. When the target temperature is reached, the main control board controls the temperature control screen to issue a reminder. When the water tank does not need to be cooled, the baffle remains closed.

[0010] In this technical solution, a temperature sensor is provided at the bottom of the water storage box, and a heating wire is provided on one side of the water storage box.

[0011] In this technical solution, the water outlet component includes a recess, a trigger, a water outlet nozzle, and a water outlet pipe.

[0012] In this technical solution, the temperature control screen can input the target water temperature;

[0013] In this technical solution, the main control board is installed in the foam layer on the back side of the refrigeration chamber. When the user inputs the target water temperature through the temperature control screen, the main control board collects the temperature of the temperature sensor in real time, compares the target water temperature with the sensor temperature, and controls the baffle to open or turns on the heating wire for heating until the target water temperature is reached.

[0014] In this technical solution, after the main control board controls the water temperature to reach the target water temperature, the temperature control screen controlled by the main control board will issue a reminder.

[0015] In this technical solution, the refrigerator includes a refrigerator compartment; at least one refrigerator compartment door for opening and closing the refrigerator compartment; a water dispenser component configured to supply water and installed on the refrigerator compartment door; the water dispenser component includes a water storage component, a water outlet component, and a temperature control screen capable of inputting a target water temperature; the water storage component includes a water storage box arranged on one side of the refrigerator compartment door; a temperature sensor for detecting the water temperature in the water storage box; an air duct plate, the outside of which is connected to a main body supply pipe, and one end of the main body supply pipe is provided with a main body supply pipe air outlet and a baffle; the water storage box has a door supply pipe air inlet and a door supply pipe on the side close to the refrigerator compartment, and when the refrigerator compartment door is closed, the door supply pipe air inlet corresponds to the main body supply pipe air outlet, and the baffle can cool the water storage box by adjusting the switch state; a heating wire is provided on one side of the water storage box.

[0016] The main control board is used to respond to the target water temperature input by the user through the temperature control screen, obtain the water temperature of the water box measured by the temperature sensor in real time, compare the target water temperature with the water temperature of the water box, and decide the next operation; during the execution of the above operation, when the water temperature of the water box is higher than the water temperature of the temperature sensor, the main control board controls the damper to open so that the cold air enters the door supply pipe inlet of the door supply pipe from the main supply pipe outlet, so that the water temperature of the water box drops to the target temperature, and controls the temperature control screen to remind the user to drink; during the execution of the above operation, when the water temperature of the water box is lower than the water temperature of the temperature sensor, the main control board controls the heating wire to be energized so that the water temperature of the water box rises to the target temperature, and controls the temperature control screen to remind the user to drink; and when the user selects the keep warm instruction through the temperature control screen, the main control board will continue to issue commands intermittently and continue to execute the above operation to keep the water temperature in the water box at the target water temperature set by the user last time.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In a refrigerator with a water dispenser assembly provided by an embodiment of the present invention, when a specific water temperature is required, a target water temperature is input into the temperature control panel. The control panel then compares the target water temperature with the water temperature measured by the temperature sensor in the water tank and adopts a specific heating or cooling strategy. When the target water temperature is lower than the water temperature measured by the temperature sensor, the control panel controls the damper in the main body supply pipe outlet to open, allowing cold air to enter the door supply pipe inlet. This cooling mechanism uses the cold air from the cabinet to directly cool the water tank, and the corresponding air duct assembly is provided between the cabinet and the door, achieving rapid cooling of the water tank while also sharing resources. When the target water temperature is higher than the water temperature measured by the temperature sensor, the control panel controls the heating wire to start heating and controls the damper in the main body supply pipe outlet to close, preventing heat from entering the air duct and affecting the cooling effect, until the target water temperature is reached. When the target water temperature is equal to the water temperature measured by the temperature sensor, the control panel controls the damper in the main body supply pipe outlet to close, stopping the heating wire from heating, and simultaneously controls the temperature control panel to issue a reminder. The damper configuration reduces cold air waste and energy consumption.

[0019] According to the water outlet temperature set by the user, by switching the working states of the refrigeration device and the heating device, the purpose of providing users with drinking water at any temperature between 0℃ and 80℃ in a short time is achieved, which meets the diverse usage requirements of users, minimizes the occupancy rate of the internal space of the refrigerator, increases the volume of the refrigerator, reduces production costs and energy consumption, ensures the reliability, stability and safety of the refrigerator, and improves the product performance and user experience.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0036] In one embodiment of the present application, see Figure 1 The refrigerator includes: a box body 1 that defines its appearance, a refrigerator door 21 movably connected to the box body 1, and an air duct plate 4 at the rear of the box body 1.

[0037] The box 1 comprises an inner liner, an outer shell, and a foam layer. The inner liner is located within the outer shell, with a foam layer filling the space between the two, which provides good insulation. An air duct panel 4 is located within the inner liner, forming an air duct at the back and a cooling chamber at the front.

[0038] The interior of the housing 1 defines a storage compartment for storing food. The storage compartment includes a refrigerator compartment 2 and a freezer compartment (not shown) disposed below the refrigerator compartment 2. Specifically, in this embodiment, a bottom-cooling type refrigerator in which the refrigerator compartment 2 is disposed above the freezer compartment will be described as an example (not shown).

[0039] The cabinet doors include: a refrigerator compartment door for opening and closing the refrigerator compartment 2, and a freezer compartment door for opening and closing the freezer compartment.

[0040] In other embodiments of the present application, the refrigerating chamber 2 provides a refrigerating chamber door 21 to open and close the refrigerating chamber 2. Alternatively, the refrigerating chamber door 21 may also include a plurality of doors respectively arranged on the left and right sides, and the first refrigerating chamber door can move independently relative to the second refrigerating chamber door.

[0041] The refrigerator door 21 includes an outer shell and a door liner coupled to the outer shell. The door liner defines the back of the refrigerator door 21. A circle of sealing strips is fixed on the inside of the refrigerator door 21. When the refrigerator door 21 is closed, it prevents the loss of cold air and ensures the cooling effect of the refrigerator room 2.

[0042] like Figure 1 and Figure 2 , a water dispenser component 3 for dispensing water is provided on the door of the refrigerating chamber 2. In other embodiments of the present application, the water dispenser component 3 can be provided in any refrigerating chamber door 21.

[0043] The power supply inside the refrigerator door 21 is provided by the box body 1. The power cord passes through the upper hinge or lower hinge of the refrigerator door 21, and the power supply of the box body 1 is connected to the refrigerator door 21 through the upper hinge or lower hinge. It is used to provide power to the water dispenser component 3 on the refrigerator door 21.

[0044] The refrigerator refrigeration system provided in this embodiment of the present invention includes a compressor, a condenser, an anti-condensation tube, a filter drier, a capillary tube, an evaporator 49, a gas-liquid separator, a fan 41, and an air duct plate 4. Evaporator 49 is located at the bottom of the air duct. This placement effectively increases the refrigerator's capacity and prevents cold air from being transferred into the refrigerator through the walls of the air duct plate 4 when the compressor is stopped, thereby improving temperature uniformity within the refrigerator.

[0045] Reference Figure 3-Figure 5The refrigeration process of the refrigeration system includes compression process, condensation process, throttling process and evaporation process. The compression process is as follows: when the refrigerator power cord is plugged in and the temperature control system is turned on, the compressor starts working, and the low-temperature, low-pressure refrigerant is sucked into the compressor, compressed into high-temperature, high-pressure superheated gas in the compressor cylinder, and then discharged into the condenser; the condensation process is as follows: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, the temperature continues to drop, and is gradually cooled to a saturated vapor at room temperature and high pressure, and further cooled to a saturated liquid, and the temperature no longer drops. The temperature at this time is called the condensation temperature, and the pressure of the refrigerant remains almost unchanged during the entire condensation process; the throttling process is as follows: : The saturated liquid refrigerant after condensation is filtered out of moisture and impurities by the drying filter and then flows into the capillary tube, through which it is throttled and reduced in pressure, and the refrigerant becomes wet steam at room temperature and low pressure; the evaporation process is: the wet steam at room temperature and low pressure begins to absorb heat and vaporize in the evaporator 49, which not only reduces the temperature of the evaporator 49 and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator 49 passes through the gas-liquid separator and returns to the compressor again, repeating the above process to transfer the heat in the refrigerator to the air outside the box, thereby achieving the purpose of refrigeration.

[0046] Furthermore, a fan 41 is positioned above the evaporator 49 within the air duct. This, combined with the multiple air outlets of the duct panel 4, effectively improves temperature uniformity within the refrigerator. Cold air in the duct is blown into the refrigerated compartment 2 through the duct panel 4. The duct panel 4 includes front air outlets 42 and side air outlets. Multiple front air outlets 42 are arranged laterally along the front of the duct panel 4, their positions dependent on the refrigerator's internal layout. To achieve a better cooling effect, side air outlets are located on both the left and right sides of the duct panel 4.

[0047] Further, refer to Figure 4 , although there is an air outlet on one side of the air duct plate 4, the air outlet is not directly connected to the storage room space, and the air outlet on one side of the air duct plate 4 is connected to the main supply pipe, and the main supply pipe 43 is buried in the foam layer of the box body 1, that is, one end of the main supply pipe 43 is fixedly connected to the air outlet on one side of the air duct plate 4, and the other end extends toward the side wall of the box body 1. When the main supply pipe 43 extends to the corner between the rear wall and the side wall of the box body 1, the main supply pipe 43 also bends accordingly to form a right angle. After the main supply pipe 43 turns to the side wall of the box body 1, it continues to extend forward along the side wall of the box body 1 until it reaches the front of the side wall of the box body 1, near the refrigerator door 21, forming the main supply pipe air outlet 44. The main supply pipe air outlet 44 faces the inside of the box body 1. Specifically, the main supply pipe 43 and the main supply pipe air outlet 44 are not limited to a specific shape, such as square, rectangular, circular, etc.

[0048] Specifically, after extending from one side of the air duct plate 4, the main supply pipe 43 continues to extend horizontally to the main supply pipe air outlet 44, or, if the position of the main supply pipe air outlet 44 is limited, it is tilted upward or downward at a certain angle. The main supply pipe air outlet 44 is located at a height between the upper hinge and the lower hinge of the refrigerator door 21. However, in other embodiments, the position of the main supply pipe 43 is not limited to this.

[0049] Reference Figure 6 The main supply pipe air outlet 44 is located at the front of the side wall of the cabinet 1. A baffle 45 is provided at the main supply pipe air outlet 44. Alternatively, the baffle 45 may be located at the other end of the main supply pipe 43, i.e., at the side air outlet of the air duct plate 4. The baffle 45 is a square structure. Specifically, the baffle 45 is not limited to a square shape and may also be a circular or irregular shape. The baffle 45 is provided according to the shape of the main supply pipe 43 to ensure that when the baffle 45 is closed, it can strictly block the flow of cold air in the main supply pipe 43.

[0050] A motor 46 is mounted on one side of the baffle 45. This motor 46 is fixed to the inner wall of the main supply pipe 43 and is connected to a gear (not shown). When the motor 46 is running, it can control the gear to rotate in different clockwise directions. When rotating clockwise or counterclockwise, the baffle 45 is in an open position, sealing the main supply pipe 43. When the motor 46 controls the gear to rotate in the other direction, the baffle 45 can be rotated to the side of the main supply pipe 43. At this point, the baffle 45 is folded, or closed, allowing the cooling air in the main supply pipe 43 to circulate.

[0051] A water dispenser component 3 is provided in the refrigerator door 21 , and the water dispenser component 3 includes a water outlet component 31 , a water storage component 32 and a temperature control screen 324 .

[0052] Reference Figure 7 The water storage component 32 includes a water storage box 321, which is fixed to the inner side of the refrigerator door 21. The water storage box 321 can be fixed to the inner liner of the refrigerator door 21 by snapping. The user can remove the water storage box 321 to add water. Specifically, in other embodiments, the fixing method of the water storage box 321 is not limited to snap fixing. The water storage box 321 can also be fixed to the inner side of the refrigerator door 21 by screws, etc. In this embodiment, the user can directly open the upper cover of the water storage box 321 to add water, which is also convenient and quick.

[0053] One side of the water storage box 321 is located near the rotating side of the refrigerator door 21 and is flush with the interior of the refrigerator door 21, making the interior of the refrigerator door 21 aesthetically pleasing and compact. A door supply pipe 47 is provided inside the water storage box 321, which connects to the main body supply pipe 43 on the side wall of the refrigerator body 1, receiving cold air from the refrigerator body 1 and achieving rapid cooling of the water storage box 321.

[0054] The water storage box 321 is located near the rotating side of the refrigerator door 21. It also has a door supply pipe air inlet 48 on one side of the water storage box 321, near the side wall of the refrigerator body 1. This inlet 48 is located vertically with respect to the water storage box 321, and the main body supply pipe air outlet 44 is positioned correspondingly to the door supply pipe air inlet 48. When the refrigerator door 21 is closed, the main body supply pipe air outlet 44 and the door supply pipe air inlet 48 align, connecting the main body supply pipe 43 to the door supply pipe 47. One end of the door supply pipe 47 serves as the door supply pipe 47 air inlet, while the other end is sealed. This allows cold air to circulate within the door supply pipe 47, more quickly lowering the water temperature in the water storage box 321.

[0055] When the main supply pipe 43 is connected to the door supply pipe 47, if the baffle 45 is opened, the cold energy in the air duct cover will be sent to the door supply pipe 47 through the main supply pipe 43, thereby cooling the water storage box 321; when the baffle 45 is closed, the cold energy in the air duct cover cannot be sent to the door supply pipe 47 through the main supply pipe 43, and at the same time, it can also prevent the heat in the water storage box 321 from entering the main supply pipe 43, affecting the cooling effect of the refrigerator compartment 2 and reducing energy consumption loss.

[0056] like Figure 1 As mentioned above, the refrigerator door 21 is provided with a mounting hole located below the water storage box 321. The mounting hole runs through the front and back of the door body and is used to install the water outlet component 31. The water outlet component 31 includes a recessed portion 311, a trigger 312, a water outlet nozzle 313 structure, and a water outlet pipe 314. The recessed portion 311 structure runs through the mounting hole and is fixed by a snap or screw device. A water receiving platform is provided below the recessed portion 311. A trigger 312 is installed above the recessed portion 311, and a water outlet nozzle 313 is installed in front of the trigger 312. The lower end of the water outlet pipe 314 is connected to the water outlet nozzle 313 outside the housing to facilitate water collection by the user. The water inlet end of the water outlet pipe 314 is connected to the water storage box 321 installed on the refrigerator door 2. When the user presses the trigger 312, the water in the water storage box 321 can flow out through the water outlet nozzle 313.

[0057] The water storage component 32 includes a water storage box 321 , a heating wire 322 and a temperature sensor 323 .

[0058] Similarly, the total power supply in the box body 1 supplies power to the temperature control screen 324 and the heating wire 322 on the refrigerator door 21, and the power line passes through the hinge at the upper or lower part of the refrigerator and extends to the inner liner of the refrigerator door 2.

[0059] like Figure 7 As shown, a plurality of heating wires 322 are laterally arranged on the front side of the water storage box 321 facing the box body 1. When the user needs to heat the water, the main control board 22 controls the heating wires 322 to turn on / off to heat the water in the water storage box 321.

[0060] In some embodiments of the present application, a temperature control screen 324 is installed on the outside of the refrigerator door 21 and is arranged in the inner container. Further, the temperature control screen 324 is arranged in the middle of the inner container.

[0061] The temperature control screen 324 is a touch screen that has both display and input functions. The user can input or select the desired water temperature, i.e., the target water temperature, through the temperature control screen 324. The water temperature information is then transmitted to the main control board 22 at the rear of the cabinet 1. The main control board 22 receives this information and responds quickly, including:

[0062] (1) The main control board 22 receives this information and compares it with the temperature detected by the temperature sensor 323;

[0063] (2) If the detected temperature is low, the heating wire 322 is controlled to start heating, and the water temperature is detected in real time. If the detected water temperature is equivalent to the set water temperature, heating is stopped until the target water temperature desired by the user is reached;

[0064] (3) If the detected water temperature is lower than the set temperature, the baffle 45 is controlled to operate so that the cooling capacity of the refrigeration system directly enters the water storage box 321 until the target water temperature desired by the user is reached.

[0065] The temperature control panel 324 is arranged on the outside of the refrigerator door 21, so that the user can select the water temperature at any time without opening the refrigerator door 21, thereby preventing energy consumption caused by loss of cold energy.

[0066] The temperature sensor 323 is arranged on the outside of the bottom of the water storage box 321 and is used to detect the real-time water temperature of the water storage box 321; alternatively, the temperature sensor 323 can also be set at other positions of the water storage box 321 as long as it does not affect the water temperature detection, and can even be set on the outside of the water tank.

[0067] The temperature sensor 323 detects the temperature and sends feedback to the main control board 22. When the temperature of the temperature sensor 323 reaches the target temperature set in the main control board 22, the main control board 22 issues a command to the temperature control screen 324. The temperature control screen 324 responds to the command of the main control board 22 and reminds the user that it is time to drink. Specifically, the reminder method is not limited to screen display, voice reminder, etc.

[0068] The main control board 22 is connected to the water dispenser component 3 and the temperature sensor 323 respectively, and the main control board 22 exchanges information with the water dispenser component 3 and the temperature sensor 323 respectively, and obtains the temperature of the water storage box 321 currently detected by the temperature sensor 323 in real time. At the same time, according to the temperature of the water storage box 321, the temperature of the water storage box 321 of the water dispenser component 3 is controlled.

[0069] Specifically, see Figure 8 and Figure 9 , is a flow chart of the work performed by the main control board 22 of the refrigerator in an embodiment of the present invention under a preferred embodiment. The main control board 22 is specifically configured to perform the following steps:

[0070] When the cabinet 1 is powered on, the main control board 22 is initialized while receiving power. When the user requests a water temperature, they enter the target water temperature on the temperature control screen 324. The main control board 22 then responds to the user's water temperature command. The main control board 22 also determines the status of the refrigerator's refrigerator door 21. If the door 21 is open, the main control board 22 controls the temperature control screen 324 to notify the user. If the door 21 is closed, the main control board 22 proceeds to the next step.

[0071] After confirming that the refrigerator door 21 is closed, the main control board 22 responds to the water temperature command input by the user and simultaneously obtains the water temperature of the water storage box 321 through the temperature sensor 323. Based on the comparison between the water temperature of the water storage box 321 and the target water temperature input by the user, different feedback is provided. When the water temperature of the water storage box 321 is lower than the target water temperature, the main control board 22 controls the heating wire to turn on. When the heating wire turns on, the water temperature detected by the temperature sensor 323 is fed back to the main control board 22 in real time until the water temperature detected by the temperature sensor 323 reaches the target water temperature. At this point, the main control board 22 immediately controls the heating wire to stop heating and controls the temperature control screen 324 to alert the user.

[0072] When the water temperature of the water storage box 321 detected by the temperature sensor 323 is higher than the target water temperature, the main control board 22 controls the baffle 45 to open. At this time, the cold energy in the main supply pipe 43 enters the door supply pipe air inlet 48 through the main supply pipe air outlet 44, and the cold energy circulation is realized in the water storage box 321. At this time, the water temperature in the water storage box 321 drops rapidly, and the water temperature detected by the temperature sensor 323 will be fed back to the main control board 22 in real time until the water temperature detected by the temperature sensor 323 drops to the target water temperature. At this time, the main control board 22 will immediately control the baffle to close the main supply pipe 43, and at the same time, the main control board 22 controls the temperature control screen 324 to remind the user.

[0073] When the water temperature of the water storage box 321 detected by the temperature sensor 323 is the same as the target water temperature, the main control board 22 will directly control the temperature control screen 324 to remind the user.

[0074] When the user selects the keep warm instruction, the main control board 22 will continue to issue commands intermittently and continue to perform the above operations so that the water temperature in the water storage box 321 is maintained at the water temperature instruction set by the user last time, and the temperature control screen 324 will continue to display the water temperature.

[0075] In this embodiment of the present invention, when a user requests a water temperature, they can select their desired temperature on the temperature control screen 324 based on their preferences and needs. The user-selectable water temperature range is between 0°C and 80°C. Furthermore, the temperature sensor 323 is installed in the corresponding mounting position of the selected water storage box 321, and the water dispenser's heating or cooling function is activated. Upon receiving the user's input water temperature command, the water dispenser's main control board 22 responds to the command by acquiring and recording the current temperature of the water storage box 321 detected by the temperature sensor 323 in real time.

[0076] In the case 1 provided by the embodiment of the present invention, since the water dispenser component 3 described in any of the above-mentioned embodiments is disposed within the refrigerator compartment, when water is needed, the trigger member 312 can be pressed, causing the trigger member 312 to move linearly in a horizontal direction perpendicular to the recess 311 to trigger the water outlet switch. Because the trigger member 312 moves linearly, compared to the rotational solution of the prior art, the movement of the trigger member 312 occupies less space, thereby reducing the volume of the housing. This also reduces the amount of foam layer removed when the inner wall of the case 1 is embedded in the housing, allowing more foam layer to remain on the side walls of the refrigerator, thereby improving the refrigerator's cooling effect.

[0077] Those skilled in the art will appreciate that all or part of the processes in the above-described method embodiments can be implemented by instructing the relevant hardware through a computer program. The program can be stored in a computer-readable storage medium, and when executed, the program can include the processes in the above-described method embodiments. The storage medium can be a magnetic disk, an optical disk, a read-only memory (ROM), or a random access memory (RAM).

[0078] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
