Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a refrigerator. Background Technology

[0002] Refrigerators are a common household appliance. With technological advancements, refrigerators offer increasingly diverse functions. Currently, many refrigerators come with an ice maker for convenient use, providing ice for everyday tasks.

[0003] In this type of refrigerator, the ice maker is typically located in an ice-making compartment separated from the freezer or refrigerator compartment, and is supplied with water via a water inlet pipe. If a fan is installed in the freezer or refrigerator compartment where the ice maker is located, the fan will cause the air pressure in that compartment to be higher. This means that after the water supply is completed, air from that compartment can easily flow through the water inlet pipe into other spaces, causing temperature fluctuations in those spaces and increasing the refrigerator's energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerator that solves the problem in the prior art where air from the compartment containing the ice maker flows into other spaces through the water inlet pipe, causing temperature fluctuations in those spaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A refrigerator, comprising:

[0007] The container must have at least one compartment;

[0008] An ice maker is located in the first room;

[0009] A water inlet pipe extends at least from the outside of the first room to the inside of the first room, and the water inlet pipe has an inlet and an outlet, wherein the inlet is used to introduce water flow, and the outlet is arranged in the first room to lead the water flow to the ice maker; and

[0010] A valve body assembly is disposed between the outlet and the inlet, and the valve body assembly includes:

[0011] A valve seat is connected to the water injection pipe, and the valve seat is provided with a valve body channel communicating with the water injection pipe;

[0012] A valve outlet is formed in the valve seat and communicates with the valve body passage to discharge water from the valve body passage;

[0013] The adjusting block has a first end and a second end arranged opposite to each other. The first end is rotatably connected to the valve seat, so that the second end can move away from and towards the valve outlet in the extension direction of the valve body channel with the first end as the fulcrum.

[0014] A counterweight is connected to the first end and extends away from the valve outlet, so that the counterweight and the adjusting block extend to opposite sides of the fulcrum to form a lever structure, thereby allowing the adjusting block to connect with the valve outlet and close the valve outlet.

[0015] The above technical solution has the following advantages: When the water supply pipe stops, the lever structure formed by the counterweight and the adjusting block allows the valve body assembly to connect the adjusting block to the valve outlet under the action of the counterweight. This closes the valve outlet without the need for additional power. In this way, even if the cold air in the first chamber can enter the water supply pipe through the outlet and flow to other spaces along the water supply pipe, when this cold air flows to the valve body assembly, it will be trapped between the outlet and the valve body assembly because the valve outlet of the valve body assembly is closed by the adjusting block. This prevents the cold air in the first chamber from flowing to other spaces through the water supply pipe and causing temperature fluctuations in other spaces.

[0016] When the water supply pipe begins, the water flows from the inlet to the outlet, entering the valve body channel. At this point, the water's own potential energy drives the regulating block to rotate around its fulcrum. Without additional power, the regulating block moves away from the valve outlet, opening it. Since the valve body channel is connected to the water supply pipe, the water flows out of the valve body channel and continues towards the outlet, where it is led by the water supply pipe to the ice maker, thus completing the ice-making process.

[0017] In some embodiments, the valve seat is provided with a connecting portion that extends into the valve body channel, closing the side of the valve body channel where the connecting portion is located, and a gap is left between the side of the valve body channel away from the connecting portion and the connecting portion, thereby forming the valve outlet; and...

[0018] The adjusting block is rotatably connected to one end of the connecting part near the valve outlet, and can rotate with its connection point to the connecting part as a fulcrum;

[0019] A second gap is formed between the counterweight and the connecting part, allowing the counterweight to move within the second gap.

[0020] The above technical solution has the following advantages: Because the connecting part closes the valve body channel on one side, the area of ​​the valve outlet is smaller than the channel area of ​​the valve body channel. Therefore, when water is supplied through the injection pipe, the water flow entering the valve body assembly is guided by the connecting part and converges to the valve outlet, ensuring the outlet is filled with water and preventing air from escaping. This prevents air from the first chamber from flowing through the valve body channel when water is supplied through the injection pipe. Furthermore, as the area of ​​the valve outlet decreases, the adjusting block can close the valve outlet with a smaller coverage area. This allows for miniaturization of the adjusting block's dimensions, and makes it easier for the counterweight to achieve lever balance with the adjusting block.

[0021] In some embodiments, along the extending direction of the valve body channel, the valve seat extends towards the front end from the side away from the connecting portion to form a first extension; and,

[0022] The connecting portion extends toward the front end of the first extension portion, such that the connecting portion is inclined in the extension direction of the valve body channel; and the adjusting block is configured to connect to the front end of the first extension portion to close the valve outlet.

[0023] The above technical solution has the following advantages: Since the valve seat extends towards the front end from the side away from the connecting part, the first extension is located at the front end of the connecting part. Therefore, when the connecting part extends towards the front end of the first extension, it tilts towards the extension direction of the valve body channel, thus forming a guiding structure to guide the water flow to the valve outlet. In this way, when water is supplied by the water injection pipe, the water flow falls on the connecting part and is guided towards the valve outlet, ensuring that the water flow passes smoothly through the valve body assembly. Moreover, since the adjusting block is constructed to connect with the front end of the first extension, it also tilts towards the extension direction of the valve body channel. Compared to the adjusting block being arranged perpendicular to the extension direction of the valve body channel, the adjusting block can fully open the valve outlet with a smaller rotation angle when water is supplied by the water injection pipe. Furthermore, when water is stopped from being supplied by the water injection pipe, the adjusting block can abut against the front end of the first extension with a small rotation angle, closing the valve outlet. It is easier for the adjusting block to seal the valve outlet.

[0024] In some embodiments, the valve body channel is arranged vertically, and the valve outlet is oriented downwards.

[0025] The above technical solution has the following advantages: Since the valve body channel is arranged in the vertical direction, the water flow entering the valve body channel will maintain a certain gravitational potential energy, so that the water flow in the valve body channel can drive the regulating block to rotate, causing the valve outlet to open, thereby avoiding water accumulation in the valve body assembly.

[0026] In some embodiments, the adjusting block extends toward the front end of the valve seat and is inclined to the horizontal plane; when the adjusting block is in contact with the valve outlet, the adjusting block forms an angle α with the horizontal plane, and 30°≤α≤60°.

[0027] The above technical solution has the following advantages: The angle α between the adjusting block and the horizontal plane affects the lever arm length between the adjusting block and the fulcrum. When 30°≤α, the adjusting block can be positioned closer to the connecting part within the same valve body channel inner diameter, allowing the valve body assembly to appropriately enlarge the valve outlet area to ensure the water output of the valve body assembly. When α≤60°, the adjusting block can ensure a suitable lever arm length between the adjusting block and the fulcrum within the same valve body channel inner diameter, and also avoids the problem of the adjusting block being unable to close the valve outlet due to an excessively large angle α.

[0028] In some embodiments, a baffle block is provided in the valve body channel. The baffle block is arranged at the rear end of the valve outlet and has a connecting end and a baffle end arranged opposite to each other. The connecting end is connected to the inner wall of the valve body channel, and the baffle end extends away from the first end and forms an overflow port with the valve body channel.

[0029] The above technical solution has the following advantages: When water is injected into the water injection pipe but the water volume is insufficient to completely fill the pipe, because the area of ​​the overflow port is smaller than the channel area of ​​the valve body channel, the water flowing into the valve body channel can fill the overflow port. As a result, the cold air entering the valve body channel through the valve outlet is constrained by the baffle block, limited to between the valve outlet and the overflow port, thus preventing cold air from flowing outwards during the water injection process. Furthermore, since the baffle block is located at the rear end of the connection, the water flowing into the valve body channel will reach the baffle block before reaching the connection. Under the obstruction of the baffle block, the water flow needs to flow along the extension direction of the baffle block to the overflow port, and then continue flowing towards the valve outlet. During this process, the flow direction of the water is changed by the baffle block, thereby slowing down the flow velocity and reducing the impact of the water flow on the connection.

[0030] In some embodiments, the partition block extends along the extension direction of the valve body channel, such that the partition block is arranged at an angle toward the front end of the valve seat.

[0031] The above technical solution has the following advantages: the water flow entering the valve body channel will flow from the rear end of the valve seat to the front end of the valve seat. Since the baffle block is arranged at an incline towards the front end of the valve seat, the water flow entering the valve body channel can maintain its flow towards the valve outlet, ensuring the smooth flow of water inside the valve body assembly.

[0032] In some embodiments, there are multiple baffles, which are staggered along the extension direction of the valve body channel, and the flow port closest to the valve outlet is located at the rear end of the connection portion, so that water flows through the connection portion into the valve outlet.

[0033] The above technical solution has the following advantages: multiple baffles are arranged in an alternating manner, which can form a maze-like path in the valve body channel, so that the flow rate of water entering the valve body channel can be effectively slowed down.

[0034] In some embodiments, the water injection pipe includes a first connecting fitting and a second connecting fitting, both of which are hollow structures.

[0035] The water inlet is located at the first connecting pipe fitting, and the first connecting pipe fitting is sleeved on one side of the valve seat.

[0036] The water outlet is located on the second connecting pipe fitting, and the second connecting pipe fitting is sleeved on the other side of the valve seat.

[0037] The above technical solution has the following advantages: the water injection pipe is formed by the first connecting pipe and the second connecting pipe, and the valve body assembly can be detachably connected to the water injection pipe, so that the valve body assembly can be conveniently connected and assembled with the water injection pipe.

[0038] In some embodiments, the valve seat has a mounting block on its outer surface, the mounting block being arranged circumferentially along the valve seat and extending outward from the valve seat.

[0039] The above technical solution has the following advantages: the mounting block can provide a reference for the installation and positioning of the valve seat, so that when the first connecting pipe and the second connecting pipe are sleeved on the outside of the valve seat, they can respectively abut against the mounting block, ensuring that the first connecting pipe, the second connecting pipe and the valve seat are tightly connected.

[0040] Compared with the prior art, the refrigerator implemented in this utility model has the following advantages:

[0041] This refrigerator invention utilizes a valve assembly in the water inlet pipe to control the flow between the inlet and outlet. A counterweight and an adjusting block work together to form a lever structure with the first end as the fulcrum. When the water supply stops, the valve assembly allows the second end of the adjusting block to move closer to the valve outlet along the extension direction of the valve channel, thus connecting the adjusting block to the valve outlet. This allows the valve assembly to close the valve outlet without additional power, trapping cold air in the freezer compartment between the outlet and the valve assembly, preventing it from entering other spaces. This avoids cold air from the first compartment flowing through the water inlet pipe to other spaces and causing temperature fluctuations in those compartments. Furthermore, when the water supply begins, the water flow, based on its own potential energy, drives the adjusting block to rotate around the fulcrum, causing the second end of the adjusting block to move away from the valve outlet along the extension direction of the valve channel, opening the valve outlet and enabling ice-making water injection.

[0042] Furthermore, the refrigerator of this invention provides a connecting part on the valve seat, which guides the water flow entering the valve body assembly to the valve outlet, allowing the valve outlet to be filled with water and preventing air from escaping from the valve outlet. This also prevents cold air in the first compartment from flowing through the valve body channel when water is supplied by the water inlet pipe.

[0043] Furthermore, the refrigerator of this invention, by incorporating a baffle block, ensures that the water flow entering the valve body channel fills the outlet, thereby confining the cold air entering the valve body channel from the valve outlet to between the outlet and the outlet. This prevents cold air from flowing out during the water injection process. Moreover, since the baffle block is located at the rear end of the connection, the water flow entering the valve body channel reaches the baffle block before reaching the connection. Due to the baffle block's obstruction, the water flow must follow its extension direction to the outlet, and then continue flowing towards the valve outlet. During this process, the change in water flow direction due to the baffle block slows down the flow velocity, thus reducing the impact of the water flow on the connection.

Detailed Implementation

[0056] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0057] In the description of this utility model, it should be understood that when an element is referred to as "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to or indirectly connected to the other element.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0058] In the description of this utility model, it should be understood that the terms "height," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0059] In the description of this utility model, it should be understood that 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 number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0060] See Figure 1-2 As shown, this utility model embodiment provides a refrigerator 100, including a cabinet 1 and a door 2. The cabinet 1 has a take-out opening 3. The door 2 is connected to the cabinet 1 and can move relative to the cabinet 1 to open and close the take-out opening 3.

[0061] The cabinet 1 is generally a rectangular frame structure, including a shell 1a and a liner 1b. The liner 1b is located inside the shell 1a, and a foamed space (not shown in the figure) is formed between the liner 1b and the shell 1a. The foamed space is used to install other components of the refrigerator 100 and to form a foamed insulation layer. The shell 1a provides protection and support for the liner 1b. A refrigeration compartment is formed inside the liner 1b for storing food. An access port 3 is located on one side of the refrigeration compartment for easy access to items inside. The door 2 is rotatably connected to the shell 1a of the cabinet 1; for example, the door 2 and the shell 1a can be rotatably connected or slidably connected.

[0062] In some embodiments, the refrigerator 100 further includes a refrigeration system (not shown) and an air supply system (not shown), which are electrically connected to a power supply component. The power supply component is used to supply power to the various components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0063] The refrigeration system is installed inside the outer shell 1a and is used to supply cold air to the refrigeration compartment inside the inner shell 1b. A refrigeration system typically refers to a closed system composed of components such as a compressor, evaporator, condenser, dryer filter, return pipe, and throttling device, along with refrigerant. Each component is distributed in different positions within the outer shell 1a according to its structural characteristics to meet its corresponding functional requirements. The working process of the refrigeration system mainly includes compression, condensation, throttling, and evaporation. The compression process is as follows: After the power cord of the refrigerator 100 is plugged in, with the thermostat contacts closed, the compressor starts working. The low-temperature, low-pressure refrigerant from the evaporator is drawn into the compressor and compressed into high-temperature, high-pressure refrigerant gas before being discharged into the condenser. The condensation process is as follows: The high-temperature, high-pressure refrigerant gas exchanges heat with the external environment through the condenser, its temperature decreases, and it is gradually cooled into room-temperature, high-pressure saturated refrigerant vapor, and then further cooled into saturated refrigerant liquid. The throttling process is as follows: The condensed saturated liquid refrigerant is filtered through a dryer to remove moisture and impurities before flowing into the throttling device. The device reduces pressure and transforms the refrigerant into low-pressure, room-temperature wet vapor. The evaporation process: This low-pressure, room-temperature wet vapor enters the evaporator, absorbs heat, and vaporizes, lowering the temperature of the evaporator and its surroundings, thus achieving refrigeration. This process also transforms the refrigerant into a low-temperature, low-pressure gas. The refrigerant exiting the evaporator returns to the compressor, repeating the above process. Through the change in the refrigerant's state, energy is converted, transferring heat from inside the refrigerator 100 to the outside air, thereby achieving the refrigeration cycle of the refrigerator 100.

[0064] An air supply system is installed inside the housing 1a to provide power for the flow of cold air. The air supply system generally includes a fan and an air supply duct defined within the housing 1a. In some embodiments, the air inlet of the air supply duct is located close to the fan, and the air outlet is located away from the fan. In other embodiments, the air outlet of the air supply duct is located close to the fan, and the air inlet is located away from the fan. An air duct cavity is also defined within the housing 1a, which communicates with both the air supply duct and the refrigeration chamber inside the housing liner 1b, allowing the air supply duct to communicate with the refrigeration chamber through the air duct cavity. It should be noted that the housing liner 1b has an air outlet, which connects the air duct cavity and the refrigeration chamber. The fan draws cold air generated by the refrigeration system through the air supply duct into the air duct cavity and then flows through the air outlet to the refrigeration chamber to cool it. It should also be noted that in some embodiments, the air outlet is located on the side wall opposite to the access port 3 of the refrigeration chamber 1b or on the side wall adjacent to the access port 3 of the refrigeration chamber 1b; it should also be noted that the refrigeration system and the air supply system are common knowledge in the art and will not be described in detail here.

[0065] like Figure 1-11 As shown, the refrigerator 100 of this embodiment has multiple compartments inside the cabinet 1, namely a freezer compartment 4 and a refrigerator compartment 5. The upper and lower parts are distinguished by the upper and lower sides when the refrigerator 100 is in normal operation. The freezer compartment 4 is located below the refrigerator compartment 5. The freezer compartment 4 is used as the first compartment in this embodiment. An ice maker 6 is installed in the freezer compartment 4, and a water supply unit 7 is installed in the refrigerator compartment 5.

[0066] Water inlet pipe 8 extends from the refrigerator compartment 5 into the freezer compartment 4. Water inlet pipe 8 has an inlet 8a and an outlet 8b, wherein the inlet 8a is connected to the water supply component 7 to introduce water flow; the outlet 8b is arranged in the freezer compartment 4 and above the ice maker 6 to lead water flow out to the ice maker 6.

[0067] A valve body assembly 9 is provided on the water injection pipe 8. The valve body assembly 9 is arranged between the water outlet 8b and the cold storage compartment 5. The valve body assembly 9 includes a valve seat 9a, a valve outlet 9b, an adjusting block 9c, and a counterweight 9d. The valve seat 9a is connected to the water injection pipe 8 and has a valve body channel 9e that communicates with the water injection pipe 8. The valve outlet 9b is formed on the valve seat 9a and communicates with the valve body channel 9e to discharge water from the valve body channel 9e. The adjusting block 9c has a first end 9d arranged opposite to it. The first end 90c is rotatably connected to the valve seat 9a, so that the second end 91c can move away from and towards the valve outlet 9b in the extension direction of the valve body channel 9e with the first end 90c as the fulcrum. The counterweight 9d is connected to the first end 90c and extends away from the valve outlet 9b, so that the counterweight 9d and the adjusting block 9c extend to the opposite sides of the fulcrum, so that the adjusting block 9c can be connected to the valve outlet 9b, thereby closing the valve outlet 9b.

[0068] The counterweight 9d is connected to the first end 90c of the adjusting block 9c, and the first end 90c of the adjusting block 9c is rotatably connected to the valve seat 9a. This causes the counterweight 9d and the adjusting block 9c to cooperate with each other, forming a lever structure with the first end 90c as the fulcrum. By controlling the weight of the counterweight 9d and the distance between the counterweight 9d and the fulcrum, the adjusting block 9c can be tilted up and then connected to the valve outlet 9b, thereby closing the valve outlet 9b.

[0069] Understandably, the torque generated by the counterweight 9d at the fulcrum is preferably greater than or equal to the torque generated by the adjusting block 9c at the fulcrum, to ensure that the adjusting block 9c remains engaged with the valve outlet 9b, keeping the valve outlet 9b normally closed. Furthermore, a sealing layer can be arranged on the end of the adjusting block 9c facing the valve outlet 9b, with the sealing layer engaging with the valve outlet 9b, thereby improving the sealing performance of the adjusting block 9c.

[0070] By providing a valve assembly 9 between the water outlet 8b and the refrigerator compartment 5, the refrigerator 100 of this embodiment is able to control the flow of the water inlet pipe 8 between the water inlet 8a and the water outlet 8b. When the water supply to the water inlet pipe 8 stops, the counterweight 9d can bring the second end 91c of the adjusting block 9c closer to the valve outlet 9b in the extension direction of the valve body channel 9e, so that the adjusting block 9c is connected to the valve outlet 9b. This allows the valve body assembly 9 to close the valve outlet 9b without additional power. In this way, even if cold air from the freezer compartment 4 enters the water inlet pipe 8 due to the influence of the fan and flows along the water inlet pipe 8 to the refrigerator compartment 5, when this cold air flows to the valve body assembly 9, it will be trapped between the outlet 8b and the refrigerator compartment 5 because the valve outlet 9b of the valve body assembly 9 is closed by the adjusting block 9c. This prevents the cold air from the freezer compartment 4 from flowing to other compartments through the water inlet pipe 8 and causing temperature fluctuations in other compartments.

[0071] When the water supply pipe 8 starts supplying water, as the water flows from the inlet 8a to the outlet 8b, when the water enters the valve body channel 9e and contacts the regulating block 9c, the water, based on its own flow potential energy, exerts a force on the regulating block 9c towards the outside of the valve body channel 9e. This force increases the torque on one side of the regulating block 9c, thereby breaking the lever balance formed by the regulating block 9c and the counterweight 9d, pushing the regulating block 9c to rotate around the fulcrum until the lever arm of the regulating block 9c at the fulcrum is reduced to a suitable size, and the regulating block 9c and the counterweight 9d reach a new balance. At this time, the second end 91c of the regulating block 9c moves away from the valve outlet 9b in the extension direction of the valve body channel 9e, and the valve outlet 9b opens. Since the valve body channel 9e is connected to the water supply pipe 8, after the water flows out of the valve body channel 9e through the valve outlet 9b, it continues to flow towards the outlet 8b and is led out by the water supply pipe 8 to the ice maker 6, realizing ice making and water supply.

[0072] Moreover, when the water supply pipe 8 stops, the force exerted by the water flow on the regulating block 9c will disappear after the water flows out from the valve outlet 9b. This reduces the torque on one side of the regulating block 9c, causing the lever structure formed by the regulating block 9c and the counterweight 9d to lose balance again. At this time, the counterweight 9d will drive the regulating block 9c to rotate around the fulcrum until the lever arm of the regulating block 9c at the fulcrum increases to a suitable size, so that the regulating block 9c and the counterweight 9d reach a new balance. In this way, the regulating block 9c will reconnect to the valve outlet 9b, closing the valve outlet 9b, thereby preventing the cold air in the freezer compartment 4 from flowing into other compartments through the water supply pipe 8 and causing temperature fluctuations in other compartments.

[0073] It should be noted that the freezing compartment 4 being located below the refrigerator compartment 5 is merely an example in this embodiment. In the refrigerator 100 product, the freezing compartment 4 is not necessarily located below the refrigerator compartment 5. For example, in some refrigerator 100 products, the freezing compartment 4 may be located above the refrigerator compartment 5. In this case, the piping layout of the refrigerator 100 will be adjusted accordingly, but the valve body assembly 9 can still be connected to the water inlet pipe 8 and arranged between the water outlet 8b and the refrigerator compartment 5 to achieve the same piping control effect.

[0074] It should be noted that the water supply to the ice maker 6 does not necessarily use a water supply component 7, such as a water storage tank; the water supply component 7 is only used as an example in this embodiment. In other examples, the refrigerator 100 can be directly connected to an external water source, such as a tap water pipe, via a water inlet pipe 8, and the water supply to the ice maker 6 can be controlled by a valve.

[0075] It is understandable that in the lever structure formed by the counterweight 9d and the adjusting block 9c, the portion of the adjusting block 9c to the fulcrum is the effort arm of the lever structure, while the portion of the counterweight 9d to the fulcrum is the resistance arm. Therefore, the moving directions of the adjusting block 9c and the counterweight 9d are opposite. When the adjusting block 9c moves away from the valve outlet 9b in the extension direction of the valve body channel 9e, the counterweight 9d will move closer to the valve seat 9a. The extent to which the counterweight 9d can move affects the degree to which the adjusting block 9c opens the valve outlet 9b. Therefore, a certain space can be reserved between the valve seat 9a and the counterweight 9d to allow the counterweight 9d to move, ensuring that the valve outlet 9b can be opened to the required degree.

[0076] refer to Figure 6 As an example of this embodiment, the valve seat 9a is provided with a connecting part 90a, which extends into the valve body channel 9e, and closes the valve body channel 9e on one side where the connecting part 90a is arranged. A gap is left between the valve body channel 9e away from the connecting part 90a and the connecting part 90a, thereby forming a valve outlet 9b. Furthermore, the adjusting block 9c is rotatably connected to the end of the connecting part 90a near the valve outlet 9b, and can rotate with its connection point with the connecting part 90a as a fulcrum. A second gap 10 is formed between the counterweight block 9d and the connecting part 90a, so that the counterweight block 9d can move within the second gap 10.

[0077] The front end of the water flow within the valve body channel 9e is designated as the front end, and the opposite end as the rear end. A connecting portion 90a is provided on the valve seat 9a, extending into the valve body channel 9e. The front end of the connecting portion 90a has a certain space for the counterweight 9d to move. Thus, the counterweight 9d can extend to the front end of the connecting portion 90a, and is separated from the connecting portion 90a by a second gap 10, allowing the counterweight 9d to move within the second gap 10. Of course, the size of the second gap 10 affects the rotation range of the adjusting block 9c, and consequently the opening range of the valve outlet 9b. The specific size of the second gap 10 can be configured according to the specific specifications of the valve body assembly 9.

[0078] Furthermore, since the connecting part 90a closes the valve body channel 9e on one side, the area of ​​the valve outlet 9b is smaller than the channel area of ​​the valve body channel 9e. As a result, when the water supply pipe 8 supplies water, the water flowing into the valve body assembly 9 is guided by the connecting part 90a and converges at the valve outlet 9b, ensuring that the valve outlet 9b is filled with water. This prevents air from escaping from the valve outlet 9b and avoids air from the freezer compartment 4 and the refrigerator compartment 5 flowing through the valve body channel 9e when the water supply pipe 8 is supplying water. Moreover, as the area of ​​the valve outlet 9b decreases, the adjusting block 9c can close the valve outlet 9b with a smaller coverage area. This allows for a smaller size of the adjusting block 9c, making it easier for the counterweight block 9d to achieve lever balance with the adjusting block 9c.

[0079] Understandably, the lever arm size of the power arm affects the counterweight and lever arm size of the resistance arm. To avoid requiring a large counterweight for the valve body assembly 9, the lever arm of the power arm, i.e., the lever arm of the adjusting block 9c, can be adjusted appropriately. (Reference) Figure 7 As an example of this embodiment, along the extension direction of the valve body passage 9e, the valve seat 9a extends toward the front end from the side away from the connecting portion 90a to form a first extension portion 91a; and the connecting portion 90a extends toward the front end of the first extension portion 91a, so that the connecting portion 90a is inclined in the extension direction of the valve body passage 9e; and the adjusting block 9c is configured to be connected to the front end of the first extension portion 91a so as to close the valve outlet 9b.

[0080] The adjusting block 9c is configured to connect to the front end of the first extension 91a, which makes the adjusting block 9c inclined in the extension direction of the valve body channel 9e. Compared with the adjusting block 9c being arranged perpendicular to the extension direction of the valve body channel 9e, the lever arm of the adjusting block 9c can be effectively reduced. Not only can the valve outlet 9b be fully opened by rotating a smaller angle when the water injection pipe 8 supplies water, but also, when the water injection pipe 8 stops supplying water, the adjusting block 9c can be abutted against the front end of the first extension 91a by rotating a smaller angle, so that the valve outlet 9b is closed. It is easier for the adjusting block 9c to seal the valve outlet 9b.

[0081] Furthermore, since the valve seat 9a extends towards the front end from the side away from the connecting part 90a, the first extension 91a will be located at the front end of the connecting part 90a. Therefore, when the connecting part 90a extends towards the front end of the first extension 91a, the connecting part 90a will be inclined in the extension direction of the valve body channel 9e, thereby forming a guiding structure to guide the water flow to the valve outlet 9b. In this way, when the water supply pipe 8 supplies water, the water flow falls on the connecting part 90a and will be guided by the connecting part 90a to flow towards the valve outlet 9b, ensuring that the water flow passes smoothly through the valve body assembly 9.

[0082] Of course, the tilt range of the adjusting block 9c also needs to be limited to ensure that the adjusting block 9c can close the valve outlet 9b and form a seal when the water supply pipe 8 stops. (Reference) Figure 7 As an example of this embodiment, the adjusting block 9c extends toward the front end of the valve seat 9a and is inclined to the horizontal plane; when the adjusting block 9c is connected to the valve outlet 9b, an angle α is formed between the adjusting block 9c and the horizontal plane, and 30°≤α≤60°.

[0083] Understandably, the angle α between the adjusting block 9c and the horizontal plane affects the lever arm length between the adjusting block 9c and the fulcrum. When 30°≤α, the adjusting block 9c can be positioned closer to the connecting part 90a within the same valve body channel 9e inner diameter, allowing the valve body assembly 9 to appropriately enlarge the area of ​​the valve outlet 9b, thus ensuring the water output of the valve body assembly 9. When α≤60°, the adjusting block 9c can maintain a suitable lever arm length between itself and the fulcrum within the same valve body channel 9e inner diameter, also avoiding the problem of the adjusting block 9c being unable to close the valve outlet 9b due to an excessively large angle α.

[0084] Since the refrigerator compartment 5 is located above the freezer compartment 4, the water inlet pipe 8 extending from the refrigerator compartment 5 into the freezer compartment 4 generally extends from top to bottom to facilitate water flow within the pipe 8. To accommodate the arrangement of the water inlet pipe 8, the valve assembly 9 can also be arranged vertically. (Reference) Figure 5-8 As an example of this embodiment, the valve body channel 9e is arranged in the vertical direction, and the valve outlet 9b is arranged facing downward.

[0085] When the water flows in the water inlet pipe 8, it will slide downwards under the action of gravity. At this time, since the valve body channel 9e is also arranged in the vertical direction, the water entering the valve body channel 9e will maintain a certain gravitational potential energy, so that the water in the valve body channel 9e can drive the regulating block 9c to rotate, causing the valve outlet 9b to open, thereby preventing water from accumulating in the valve body assembly 9.

[0086] It should be noted that the valve body channel 9e is arranged in the vertical direction, but it is not required that the valve body channel 9e be in a completely vertical state. In combination with the arrangement path of the water injection pipe 8, the valve body channel 9e can also retain a certain tilt angle in some examples. For example, if the angle between the central axis of the valve body channel 9e and the vertical plane is in the range of 0 to 60°, then the valve body channel 9e is still arranged in the vertical direction.

[0087] To prevent excessive water flow into the ice maker 6 and subsequent splashing, the water supply component 7 is typically adapted to the specifications of the water inlet pipe 8 and the ice maker 6. In some cases where the water inlet pipe 8 is connected to the ice maker 6, the water supplied by the water supply component 7 may not completely fill the pipe. This could cause cold air from the freezer compartment 4 to enter the valve body assembly 9 from the valve outlet 9b, and then flow through the water inlet pipe 8 into the refrigerator compartment 5. To address this, a shielding structure could be added inside the valve body assembly 9.

[0088] refer to Figure 10-11As an example of this embodiment, a baffle block 11 is provided in the valve body channel 9e. The baffle block 11 is arranged at the rear end of the valve outlet 9b and has a connecting end 11a and a baffle end 11b arranged opposite to each other. The connecting end 11a is connected to the inner wall of the valve body channel 9e, and the baffle end 11b extends away from the first end 90c and forms an overflow port 12 between it and the valve body channel 9e.

[0089] When water is injected into the water injection pipe 8 but the water volume is insufficient to fill the water injection pipe 8, since the area of ​​the overflow port 12 is smaller than the channel area of ​​the valve body channel 9e, the overflow port 12 can be adapted to the water volume supplied by the water injection pipe 8, so that the water flow entering the valve body channel 9e fills the overflow port 12. In this way, the overflow port 12 will be occupied by the water flow, and the cold air in the freezer compartment 4 cannot flow through the overflow port 12 to the rear end of the valve body assembly 9. Then, the cold air entering the valve body channel 9e through the valve outlet 9b will be constrained by the baffle block 11 and restricted between the valve outlet 9b and the overflow port 12, thereby preventing the cold air from flowing through the water injection pipe 8. Furthermore, since the baffle block 11 is arranged at the rear end of the connection part 90a, the water flow entering the valve body channel 9e will reach the location of the baffle block 11 before reaching the location of the connection part 90a. Due to the obstruction of the baffle block 11, the water needs to flow along the extension direction of the baffle block 11 to the flow port 12, and then continue to flow to the valve outlet 9b through the flow port 12. During this process, the flow direction of the water will be changed due to the change of the baffle block 11, which will slow down the flow speed of the water and reduce the impact of the water flow on the connection part 90a.

[0090] Of course, in order to match the flow direction of the water and allow the water to flow smoothly within the valve body assembly 9, the baffle block 11 can extend along the extension direction of the valve body channel 9e, so that the baffle block 11 is inclined towards the front end of the valve seat 9a. In this way, the water entering the valve body channel 9e will flow from the rear end of the valve seat 9a to the front end of the valve seat 9a. Since the baffle block 11 is inclined towards the front end of the valve seat 9a, the water entering the valve body channel 9e can maintain its flow towards the valve outlet 9b, ensuring the smooth flow of water within the valve body assembly 9.

[0091] It should be noted that the number of baffle blocks 11 can be one or more. Multiple baffle blocks 11 can be arranged alternately along the extension direction of the valve body channel 9e, thereby forming a labyrinthine path within the valve body channel 9e, so that the flow velocity of the water entering the valve body channel 9e can be effectively slowed down. Moreover, the flow port 12 of the baffle block 11 closest to the valve outlet 9b can be located at the rear end of the connecting part 90a, so that the water flows through the connecting part 90a into the valve outlet 9b.

[0092] To facilitate connection between the valve body assembly 9 and the water injection pipe 8, the water injection pipe 8 could be designed as a detachable unit. (Reference) Figure 3As an example of this embodiment, the water injection pipe 8 includes a first connecting pipe 8c and a second connecting pipe 8d. Both the first and second connecting pipes 8c and 8d are hollow structures. An inlet 8a is located on the first connecting pipe 8c, which is sleeved on one side of the valve seat 9a. An outlet 8b is located on the second connecting pipe 8d, which is sleeved on the other side of the valve seat 9a. The water injection pipe 8 is formed using the first connecting pipe 8c and the second connecting pipe 8d. The valve body assembly 9 can be detachably connected to the water injection pipe 8, allowing for convenient connection and assembly between the valve body assembly 9 and the water injection pipe 8.

[0093] Furthermore, a mounting block 13 may be provided on the outer surface of the valve seat 9a. The mounting block 13 is arranged circumferentially along the valve seat 9a and extends outward from the valve seat 9a. The mounting block 13 can provide a reference for the installation and positioning of the valve seat 9a, so that when the first connecting pipe 8c and the second connecting pipe 8d are sleeved on the outside of the valve seat 9a, they can respectively abut against the mounting block 13, ensuring that the first connecting pipe 8c and the second connecting pipe 8d are tightly connected to the valve seat 9a.

[0094] In summary, this utility model embodiment provides a refrigerator 100, which, by setting a valve assembly 9 on the water inlet pipe 8, can control the flow between the water inlet 8a and the water outlet 8b of the water inlet pipe 8. Utilizing the cooperation of the counterweight 9d and the adjusting block 9c to form a lever structure with the first end 90c as the fulcrum, when the water inlet pipe 8 stops supplying water, the valve assembly 9 of the refrigerator 100 can bring the second end 91c of the adjusting block 9c closer to the valve outlet 9b in the extension direction of the valve body channel 9e, so that the adjusting block 9c is connected to the valve outlet 9b. This allows the valve assembly 9 to close the valve outlet 9b without additional power, trapping the cold air in the freezer compartment 4 between the water outlet 8b and the refrigerator compartment 5, preventing it from entering the refrigerator compartment 5. This avoids the problem of cold air in the freezer compartment 4 flowing through the water inlet pipe 8 to other compartments, causing temperature fluctuations in those compartments. Furthermore, when the water supply pipe 8 starts supplying water, the water flow, based on its own flow potential energy, can drive the regulating block 9c to rotate around the fulcrum, so that the second end 91c of the regulating block 9c moves away from the valve outlet 9b in the extension direction of the valve body channel 9e, thereby opening the valve outlet 9b and realizing ice-making water injection.

[0095] Furthermore, the refrigerator 100 of this invention provides a connecting part 90a on the valve seat 9a, so that the water flow entering the valve body assembly 9 is guided by the connecting part 90a to converge to the valve outlet 9b, so that the valve outlet 9b can be filled with water flow, preventing air from escaping from the valve outlet 9b, and preventing the air in the freezer compartment 4 and the refrigerator compartment 5 from flowing through the valve body channel 9e when water is supplied by the water inlet pipe 8.

[0096] Furthermore, the refrigerator 100 of this invention, by setting a baffle block 11, ensures that the water flowing into the valve body channel 9e fills the overflow port 12. This confines the cold air entering the valve body channel 9e through the valve outlet 9b to between the valve outlet 9b and the overflow port 12, preventing cold air from flowing out during the water injection process through the water inlet pipe 8. Since the baffle block 11 is located at the rear end of the connecting part 90a, the water flowing into the valve body channel 9e reaches the baffle block 11 before reaching the connecting part 90a. Due to the obstruction of the baffle block 11, the water needs to flow along the extension direction of the baffle block 11 to the overflow port 12, and then continue flowing towards the valve outlet 9b. During this process, the flow direction of the water is changed by the baffle block 11, thus slowing down the flow speed and reducing the impact of the water flow on the connecting part 90a.

[0097] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
