[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] As used herein, terms such as "center," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" that indicate spatial relative positions are used for ease of explanation to describe the relationship of one element or feature relative to another element or feature as shown in the accompanying drawings. Spatially relative terms may be intended to encompass different orientations of the device in use or operation other than the orientation shown in the drawings.

[0033] For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0035] Furthermore, it should be understood that although the terms "first," "second," and so on may be used herein to describe various elements or structures, these described objects should not be limited by these terms. These terms are merely used to distinguish the described objects from one another. For example, a first bearing cavity may be referred to as a second bearing cavity, and similarly, a second bearing cavity may be referred to as a first bearing cavity, without departing from the scope of protection of this application.

[0036] The embodiment of the present application provides a water valve, such as Figures 1 to 6 As shown, it is used to realize the redistribution of the water supply input into the refrigeration appliance, including a movable part 2 and a valve body 1, the valve body 1 defines a valve cavity 11, a first channel 12, a second channel 13 and a third channel 14, and the movable part 2 moves between a first position and a second position to control the opening and closing of the first channel 12, the second channel 13 and the third channel 14.

[0037] When the movable member 2 is in the first position, the first channel 12 and the second channel 13 are connected, the first channel 12 and the third channel 14 are closed, and the water flow can flow from the first channel 12 to the second channel 13 (or the water flow can flow from the second channel 13 to the first channel 12); when the movable member 2 is in the second position, such as Figure 5 and Figure 6 As shown, the first channel 12 and the third channel 14 are connected, the first channel 12 and the second channel 13 are closed, and water can flow from the first channel 12 to the third channel 14 (or water can flow from the third channel 14 to the first channel 12).

[0038] like Figure 2 and Figure 3 As shown, the movable member 2 is movably disposed in the valve cavity 11 , and the movable member 2 includes a core body 21 , a conducting hole 22 formed in the core body 21 , and a blocking portion 23 .

[0039] When the movable member 2 is located at the first position, the first channel 12 and the second channel 13 are connected through the conducting hole 22, and the blocking portion 23 cuts off the first channel 12 and the third channel 14;

[0040] When the movable member 2 is located at the second position, the first channel 12 and the third channel 14 are connected, that is, the blocking portion 23 no longer cuts off the first channel 12 and the third channel 14 , and the core 21 cuts off the first channel 12 and the second channel 13 .

[0041] The opening and closing between the first channel 12 and the second channel 13 of the water valve is controlled by a movable part 2, and the opening and closing between the first channel 12 and the third channel 14 are controlled by the movable part 2, thereby reducing the volume of the water valve and increasing the volume of the refrigerator or freezer compartment.

[0042] The core 21 moves toward or away from the second channel 13 , and the conducting hole 22 connects the second channel 13 and the first channel 12 . The blocking portion 23 is fixed outside the core 21 to open and close the third channel 14 .

[0043] The first position is a position where the movable member 2 is close to the second channel 13 , and the second position is a position where the movable member 2 is away from the second channel 13 .

[0044] The axes of the first channel 12, the second channel 13, and the third channel 14 are all located in the same plane, making the valve body compact. The axis of the third channel 14 and the axis of the second channel 13 are perpendicular to each other, and the axis of the first channel 12 is perpendicular to the axis of the second channel 13. More preferably, the axis of the first channel 12 is parallel to the axis of the third channel 14 and the axis of the first channel 12 is staggered with the axis of the third channel 14, that is, the axis of the first channel 12 and the axis of the third channel 14 are not coaxial.

[0045] like Figures 3 to 6 As shown, specifically, the conducting hole 22 is located in the middle of the core 12, and the conducting hole 22 is an "L"-shaped hole, that is, the conducting hole 22 includes a first hole end 221 formed at the end of the core close to the second channel 13, and a second hole end 222 formed at the outer wall of the core 21. The two ends of the conducting hole 22 are connected to form a channel for water to flow through.

[0046] Specifically, the blocking portion 23 is a protrusion extending outward from the outer wall of the core body 21, and an avoidance channel 15 is opened on the inner wall of the valve cavity 11. The protrusion passes through the avoidance channel 15 and extends out of the valve cavity 11, specifically extending to the channel opening 16 of the third channel 14, thereby closing or opening the channel opening 16 as the movable part moves.

[0047] The water valve defines a transfer chamber 31, which is connected to the first channel 12. When the first channel 12 serves as an inlet channel, water flows from the first channel 12 into the transfer chamber 31 (or, when the first channel 12 serves as an outlet channel, water flows from the transfer chamber 31 into the first channel 12).

[0048] The transfer chamber 31 , the third channel 14 , and the first channel 12 are arranged at 90° intervals around the axis of the valve chamber 11 . Specifically, the third channel 14 is arranged at 90° to the transfer chamber 31 , and the first channel 12 is arranged at 90° to the transfer chamber 31 .

[0049] The water valve further defines a first aperture 32 , a second aperture 33 and a third aperture 34 .

[0050] The first hole 32 communicates with the transfer chamber 31 and the first channel 12 .

[0051] The second channel 33 is located between the transfer chamber 31 and the valve chamber 11. When the movable part is in the first position, one end of the conducting hole 22 is docked with the second channel 33, and the transfer chamber 31 and the second channel 13 are connected to each other through the second channel 33 and the conducting hole 22. That is, the water in the transfer chamber 31 can flow into the second channel 13 through the second channel 33 and the conducting hole 22 in sequence (or, the water in the second channel 13 can flow into the transfer chamber 31 through the conducting hole 22 and the second channel 33 in sequence).

[0052] When the movable member 2 is in the second position, the conducting hole 22 is misaligned with the second channel 33. That is, the second hole end 222 of the conducting hole 22 is offset from the second channel 33. The second hole end 222 of the conducting hole 22 is blocked by the side wall of the valve cavity, and the second channel 33 is blocked by the outer wall of the core body 21.

[0053] The third hole 34 is located between the transfer chamber 31 and the third channel 34. When the movable part is in the second position, the blocking portion 23 disengages from the channel opening 16 of the third channel 14 so that the channel opening 16 is open, and the third channel 14 is connected with the third hole 34. The third channel 14 is connected with the transfer chamber 31 through the third hole 34. The water in the transfer chamber 31 can flow into the third channel 14 through the third hole 34 (or the water in the third channel 14 can flow into the transfer chamber 31 through the third hole 34).

[0054] When the movable member 2 is located at the first position, the blocking portion 23 is located in the avoidance channel 15 outside the channel opening 16 of the third channel 14 , and the blocking portion 23 is pressed against the channel opening 16 to close the channel opening, thereby cutting off the third channel 34 and the channel opening 16 .

[0055] In this embodiment, the water valve can be specifically used as a one-inlet and two-outlet valve, that is, it has one water inlet channel and two water outlet channels. For example, the first channel 12 is the water inlet channel, and the water flows into the first channel 12 and flows into the transfer chamber 31 through the first channel 32. The second channel 13 and the third channel 14 are both water outlet channels. As the movable part moves between the first position and the second position, the water in the transfer chamber 31 flows alternately into the second channel 13 or the third channel 14.

[0056] In other variations, the water valve can also be used as a two-inlet-one-outlet valve, that is, having two water inlet channels and one water outlet channel, with the second channel 13 and the third channel 14 both serving as water inlet channels, and the first channel 12 serving as a water outlet channel. The above is a preferred embodiment, and in other variations, the first channel 12, the second channel 13, and the third channel 14 can also serve as either water inlet channels or water outlet channels.

[0057] The water valve is provided with a driving mechanism 4, which is used to drive the movable part to reciprocate along the axis of the valve cavity.

[0058] The drive mechanism 4 includes an electric drive 41, a return spring 42 and a controller 43.

[0059] The electric driver 41 is disposed on a side of the valve chamber 11 away from the second passage 13 . The electric driver 41 drives the movable member 2 to move along the axis of the valve chamber 11 to approach the second passage 13 .

[0060] Specifically, the electric driver 41 is fixedly connected to the side of the valve body 1 facing away from the second passage 13. The electric driver 41 is in communication with the valve chamber 11, and the output shaft of the electric driver 41 telescopically moves along the axis of the valve chamber 11 toward the interior of the valve chamber 11. The output shaft of the driver 41 is directly or indirectly connected to the movable member 2. In this embodiment, the movable member 2 is fixedly connected to the output shaft of the driver 41. The controller 43 is electrically connected to the electric driver 41 to control its movement.

[0061] Preferably, the electric driver 41, the first channel 12, the second channel 13 and the third channel 14 are arranged in a circular array around the axis of the transfer chamber 31, and the electric driver 41 drives the movable part 2 to move toward the direction close to the second channel 13 to drive the movable part 2 to move from the second position to the first position.

[0062] A return spring 42 is sleeved on the outer wall of the valve core 21. One end of the return spring 42 abuts the valve cavity 11, and the other end abuts the blocking portion 23. When the movable member 2 is in the first position, the elastic deformation of the return spring 42 increases (e.g., the compression increases). After the electric actuator 41 stops driving, the return spring 42, under the action of its own elastic deformation recovery force, drives the movable member 2 away from the second channel 13, thereby moving the movable member 2 from the first position to the second position.

[0063] Of course, in a variant embodiment, the return spring 42 can be omitted and an electric driver 41 capable of bidirectional driving can be used, that is, the electric driver 41 can drive the movable part 2 to move toward the direction close to the second channel 13, and can also drive the movable part 2 to move toward the direction away from the second channel 13.

[0064] In this embodiment, a gap is left between the outer wall of the movable member 2 and the inner wall of the valve chamber 11 to allow the return spring 42 to move. Furthermore, the outer diameter of the movable member 2 is larger than the inner diameter of the second passage 13. When the movable member 2 is in the second position, the movable member 2 blocks the second passage 13, thereby isolating the second passage 13 from the valve chamber 11. In other embodiments, the outer diameter of the portion of the movable member 2 facing the second passage 13 is the same as the inner diameter of the second passage 13. When the movable member 2 is in the second position, the movable member 2 can be partially inserted into the second passage 13 to block the second passage 13.

[0065] Next, an embodiment of the present application further provides a refrigeration appliance, which may be a refrigerator.

[0066] The refrigerator includes a housing and a water channel device including the water valve. The specific structure of the water valve is as described above.

[0067] The box body includes a box shell, an inner liner nested in the box shell, and a heat-insulating material filled between the box shell and the inner liner by, for example, foaming. The interior of the inner liner defines a storage space, and the water channel device is arranged in the inner liner.

[0068] like Figure 7 and 8 As shown, the water channel device includes the water valve, the ice-making water channel 5, the distribution water channel 6, and the water supply unit. One of the ice-making water channel 5 and the distribution water channel 6 is connected to the second channel 13, and the other is connected to the third channel. In this embodiment, the distribution water channel 6 is connected to the second channel 13, and the ice-making water channel 5 is connected to the third channel 14.

[0069] The water channel device also includes a filter 72 and a water inlet pipe 71. The water supply part is connected to the filter 72 through the water inlet pipe 71. The output end of the filter 72 is connected to the first channel 12. The filter 72 includes a filter housing and a filter element. The filter element is filled in the filter housing. The water supply part filters the water through the filter 72 and then flows into the first channel 12.

[0070] The water distribution circuit 6 includes a kettle 61 and a water distribution pipe 62. The kettle 61 is connected to the second channel 13. The kettle 61 has a built-in kettle body cavity, and both the second channel 13 and the water distribution pipe 62 are connected to the kettle body cavity. A partition is provided within the kettle 61, which divides the kettle body cavity into an inner cavity and an outer cavity that are interconnected. The input end of the kettle 61 is connected to the second channel 13. Specifically, the inner cavity of the kettle 61 is connected to the water distribution pipe 62, and the outer cavity of the kettle 61 is connected to the second channel 13.

[0071] The waterway device also includes a housing 81, to which the filter 72, the water valve, and the kettle 61 are all fixed. Specifically, the housing 81 defines a first bearing cavity and a second bearing cavity. One of the water valve and the filter is fixed in the first bearing cavity, and the other is fixed in the second bearing cavity. In this embodiment, the water valve is fixed in the first bearing cavity, the filter 72 is fixed in the second bearing cavity, and the kettle 61 is fixed to the top of the housing 81.

[0072] Preferably, the kettle 61 and the filter 72 are vertically arranged vertically. More preferably, the kettle 61 and the filter 72 are arranged at an angle, specifically an acute angle, to reduce the corrosive effects of water hammer in the kettle 61. Preferably, the axis of the first channel 12, the axis of the second channel 13, the axis of the third channel 14 of the water valve, the central axis of the kettle 61, and the central axis of the filter 72 are coplanar, and the water valve and filter 72 are both located within the chamber of the supporting housing. This makes the overall structure of the waterway device compact and effectively reduces its volume.

[0073] The load-bearing housing 81 comprises a first housing 82 and a second housing 83, both of which are fastened to the load-bearing housing 81. Specifically, the first housing 82 is rotatably connected to the load-bearing housing 81 having the first load-bearing cavity, and the free end of the first housing 82 is fixedly connected to the load-bearing housing 81. The filter 72 is housed within the first housing 82 and the load-bearing housing 81. The second housing 83 is rotatably connected to the load-bearing housing 81 having the second load-bearing cavity, and the free end of the second housing 83 is fixedly connected to the load-bearing housing 81. In this embodiment, the free ends of the first housing 82 and the second housing 83 are both mounted to the load-bearing housing 81 using bolts and screw holes. In other embodiments, they can be secured using snap-fit ​​connections or rivets.

[0074] In summary, one embodiment has the following beneficial effects: the same movable part 2 in the water valve controls the on / off between the first channel 12 and the second channel 13, and controls the on / off between the first channel 12 and the third channel 14, thereby optimizing the structure of the water valve, miniaturizing the volume of the water valve, and making the structure of the water valve compact; when the internal space of the refrigerator is limited, more space can be freed up for other functions or storage space, the layout of the water system can be arranged more flexibly, the volume of the refrigerator compartment or freezer compartment can be increased, or a better installation position can be provided for other functional components (such as temperature sensors, fans, etc.).
