[0033] In order to meet the needs of users, many current refrigerators are equipped with a water supply system, which uses an external water source to provide water for some functions in the refrigerator, such as ice making. A filter element assembly is generally installed in the water supply system. After a period of use, the filter element is prone to dirt and blockage. At this time, the water flow of the entire water supply system will become smaller, and even water outages may occur.

[0034] In order to solve the above problems, the utility model provides a filter element socket 10 and a filter element assembly 100. Figure 1 A three-dimensional schematic diagram of an embodiment of a filter element assembly 100 provided by the utility model; Figure 2 for Figure 1 A cross-sectional view of the filter element assembly 100 in FIG. Figure 3 for Figure 1 Schematic diagram of the internal structure of the filter element assembly 100; Figure 4 for Figure 1 A three-dimensional schematic diagram of an embodiment of a filter element receiving seat 10; Figure 5 for Figure 4 A cross-sectional view of the filter element socket 10 in FIG.

[0035] See also Figures 1 to 5The filter element socket 10 includes a socket body 20 and a switching device, a water passage chamber 27 is formed in the socket body 20, and the water passage chamber 27 is provided with a first water inlet 23 and a first water outlet 24, and a filtering channel 21 and a water passage 22 are formed in the water passage chamber 27; the filtering channel 21 is used to communicate with the filter element 50, so that when communicating with the first water inlet 23 and the first water outlet 24, the water flowing into the first water inlet 23 is introduced into the filter element 50 for filtration and then flows out from the first water outlet 24; the water passage 22 is used to directly connect the first water inlet 23 and the first water outlet 24 when communicating with the first water inlet 23 and the first water outlet 24; the switching device is provided in the water passage chamber 27, and the switching device is used to switch one of the water passage 22 and the filtering channel 21 to communicate with the first water inlet 23 and the first water outlet 24.

[0036] In the technical solution provided by the utility model, a filter channel 21 and a water passage channel 22 are arranged in the water passage chamber 27 of the socket body 20, and then one of the water passage channel 22 and the filter channel 21 is switched through the switching device to be connected with the first water inlet 23 and the first water outlet 24, so that water flowing into the first water inlet 23 can be introduced into the filter element 50 through the filter channel 21 for filtration, and then flow out from the first water outlet 24, or directly flow out from the first water outlet 24 through the water passage channel 22. When the filter element 50 is normal, the filter channel 21 is switched through the switching device to be connected with the first water inlet 23 and the first water outlet 24. When the filter element 50 is dirty and blocked, the water passage channel 22 is switched through the switching device to be connected with the first water inlet 23 and the first water outlet 24, thereby avoiding blocking the waterway when the filter element 50 is dirty and blocked, affecting the flow of the entire water supply system.

[0037] It should be noted that the specific implementation form of the switching device is not limited, and can be a form of switching by a valve core 30, or a form of multiple control valves, etc., which is not limited here. A filter core 50 can be provided on the filter channel 21, so that water can flow out from the first water outlet 24 after being filtered by the filter core 50.

[0038] Furthermore, in one embodiment, the switching device includes a valve core 30, and the valve core 30 can be rotatably installed in the water passage chamber 27. In the technical solution of this embodiment, by rotating the valve core 30, one of the water passage channel 22 and the filter channel 21 is switched to connect with the first water inlet 23 and the first water outlet 24.

[0039] It should be emphasized that the water passage 22 and the flow passage can both be formed inside the valve core 30, or one can be located outside the valve core 30 and the other inside the valve core 30, which is not limited here.

[0040] When both are arranged inside the valve core 30, a large amount of space is required. At this time, the size of the valve core 30 needs to be made large, and the accuracy of the rotation of the valve core 30 is required to be high. Therefore, in one embodiment, the filter channel 21 is formed inside the valve core 30, and the valve core 30 and the water passage chamber 27 jointly define the water passage 22.

[0041] In this way, in the technical solution of the present embodiment, the filter channel 21 is located inside the valve core 30, and the water passage channel 22 is located outside the valve core 30, so that only one channel needs to be set inside the valve core 30, and the size of the valve core 30 does not need to be set particularly large. Moreover, during the switching process, if the filter channel 21 is required to connect the first water inlet 23 and the first water outlet 24, it is only necessary to align the two ends of the filter channel 21 with the first water inlet 23 and the first water outlet 24 respectively. When the water passage channel 22 is required to connect the first water inlet 23 and the first water outlet 24, it is only necessary to rotate the valve core 30 to offset the two ends of the filter channel 21 with the first water inlet 23 and the first water outlet 24 respectively. The water flowing into the first water inlet 23 flows to the gap between the valve core 30 and the water passage chamber 27 and flows to the first water outlet 24, so that the first water outlet 24 flows out.

[0042] At the same time, when the filter channel 21 is connected to the first water inlet 23 and the first water outlet 24, since there is a gap between the valve core 30 and the water passage chamber 27, part of the water flow is easy to flow directly to the first water outlet 24 from the gap, and when the water passage channel 22 is connected to the first water inlet 23 and the first water outlet 24, water is easy to flow into the filter channel 21 from the gap. Therefore, the filter channel 21 is provided with a second water inlet 25 and a second water outlet 26 corresponding to the first water inlet 23 and the first water outlet 24, and the filter element socket 10 also includes a switching sealing ring 48, and the switching sealing ring 48 is arranged around the outer side of the second water inlet 25 and / or the second water outlet 26.

[0043] When the filtering channel 21 is connected to the first water inlet 23 and the first water outlet 24, the second water inlet 25 is connected to the first water inlet 23, and the second water outlet 26 is connected to the first water outlet 24, so that the water flowing into the first water inlet 23 flows into the filtering channel 21 through the second water inlet 25, and then flows out from the second water outlet 26 to the first water outlet 24, and flows out to the water use end. When the water passage 22 is connected to the first water inlet 23 and the first water outlet 24, the first water inlet 23 and the second water inlet 25 are staggered, and the first water outlet 24 and the second water outlet 26 are staggered.

[0044] In the technical solution of the present embodiment, by setting the switching sealing ring 48, it can be understood that the switching sealing ring 48 divides the gap between the valve core 30 and the water passage chamber 27 into the filter channel 21 and the water passage 22, and isolates the two to prevent water from contaminating each other. The part located inside the switching sealing ring 48 is the filter channel 21, and the part located outside the switching sealing ring 48 is the water passage 22. When the switching sealing ring 48 is arranged around the second water inlet 25, the first water inlet 23 and the first water outlet 24 are connected in the filter channel 21, which can prevent water flowing into the first water inlet 23 from flowing into the water passage 22, and can also prevent water in the water passage 22 from flowing into the filter channel 21, thereby preventing water in the two channels from influencing each other.

[0045] When the switching sealing ring 48 is arranged around the second water outlet 26, when the filter channel 21 is connected to the first water inlet 23 and the first water outlet 24, it can prevent water flowing out of the second water outlet 26 from flowing into the water passage 22, and can also prevent water in the water passage 22 from directly flowing out of the first water outlet 24. When the water passage 22 is connected to the first water inlet 23 and the first water outlet 24, the switching sealing ring 48 can prevent water in the water passage 22 from flowing into the filter channel 21, thereby preventing water from leaking out of the filter element socket 10 after the filter element 50 is removed.

[0046] It should be emphasized that the switching sealing ring 48 can be only one, arranged around the second water inlet 25 or the second water outlet 26, or two, arranged around the second water inlet 25 and the second water outlet 26 respectively, which is not limited here.

[0047] During the rotation of the valve core 30, it is necessary to rotate the filter channel 21 or the water passage channel 22 to align with the first water inlet 23 and the first water outlet 24. Therefore, the rotation accuracy of the valve core 30 is relatively high. In order to achieve precise rotation, the filter element seat 10 also includes a limiting structure, which is arranged between the valve core 30 and the cavity wall of the water passage cavity 27 to limit the rotation stroke of the valve core 30. By setting the limiting structure, when the valve core 30 rotates to the second water inlet 25 of the filter channel 21 and the first water inlet 23 are aligned, and the second water outlet 26 and the first water outlet 24 are aligned, the valve core 30 is restricted from continuing to rotate, thereby avoiding the occurrence of excessive rotation amplitude.

[0048] Specifically, the specific implementation form of the limit structure is not limited, and it can be a plurality of stop blocks, for example, two stop blocks are arranged at intervals along the circumference of the valve core 30. When the valve core 30 rotates to the point where the filter channel 21 is connected with the first water inlet 23 and the first water outlet 24, the valve core 30 stops with one of the stop blocks to limit its continued rotation. When the valve core 30 rotates back to the point where the water passage 22 is connected with the first water inlet 23 and the first water outlet 24, the valve core 30 stops with another stop block to prevent the valve core 30 from continuing to rotate. Of course, it can also be a solution of a limit groove 40 or a limit hole, etc., which is not limited here.

[0049] In one embodiment, the limiting structure includes a limiting groove 40 and a limiting protrusion 41, one of the limiting groove 40 and the limiting protrusion 41 is set on the valve core 30, and the other is set on the cavity wall of the water passage cavity 27. When the valve core 30 rotates to abut one end of the limiting groove 40, the filter channel 21 is connected with the first water inlet 23 and the first water outlet 24. When the valve core 30 rotates to abut the limiting protrusion 41 with the other end of the limiting groove 40, the filter channel 21 is misaligned with the first water inlet 23 and the first water outlet 24, and the water passage 22 is connected with the first water inlet 23 and the first water outlet 24, so that water can flow out directly without being filtered by the filter element 50.

[0050] It should be noted that the limiting structure can be set at any circumferential position of the valve core 30 , and is not limited here. In the present embodiment, the limiting structure is set at the top end of the valve core 30 .

[0051] Furthermore, the rotation of the valve core 30 may be driven by providing a driving device, or by providing an operating portion so that the user operates the operating portion to rotate the valve core 30, etc., which is not limited here.

[0052] In one embodiment, a linkage portion is provided on the valve core 30 , and the linkage portion is used to cooperate with the matching portion 51 on the filter element 50 to achieve synchronous rotation of the filter element 50 and the valve core 30 .

[0053] In the technical solution of the present embodiment, considering that the filter element 50 needs to be rotated during the installation or removal, the linkage part is provided. During the removal of the filter element 50, the filter element 50 is first rotated. At this time, the valve core 30 is driven to rotate synchronously by the linkage part, and the state in which the filter channel 21 is connected to the first water inlet 23 and the first water outlet 24 is switched to the state in which the water passage 22 is connected to the first water inlet 23 and the first water outlet 24. After the installation relationship between the linkage part and the matching part 51 is released, the disassembly of the filter element 50 is completed. During the installation of the filter element 50, the linkage part and the matching part 51 are first assembled. Then, the filter element 50 is rotated to switch from the state in which the water passage 22 is connected to the first water inlet 23 and the first water outlet 24 to the state in which the filter channel 21 is connected to the first water inlet 23 and the first water outlet 24.

[0054] It should be noted that the specific implementation form of the linkage portion and the matching portion 51 is not limited, and may be a combination of a card slot 42 and a card block, or may be in the form of a gear set, etc., which is not limited here.

[0055] In one embodiment, the linkage portion includes a slot 42, and the slot 42 is extended along the length direction of the filter element assembly 100. With such a configuration, when the filter element 50 rotates, the slot 42 and the buckle on the filter element 50 cooperate to drive the valve core 30 to rotate synchronously, and the configuration of the slot 42 can facilitate the disassembly and assembly of the filter element 50.

[0056] To achieve the above-mentioned purpose, the present application further proposes a filter element assembly 100, comprising: a filter element seat 10 and a filter element 50, the filter element seat 10 comprising a seat body 20 and a switching device, a water passage chamber 27 is formed in the seat body 20, and the water passage chamber 27 is provided with a first water inlet 23 and a first water outlet 24, a filter channel 21 and a water passage channel 22 are formed in the water passage chamber 27; the filter channel 21 is used to communicate with the filter element 50, so that when communicating with the first water inlet 23 and the first water outlet 24, the first water inlet 23 and the first water outlet 24 are connected to the filter element 50. The water flowing into 23 is introduced into the filter element 50 for filtration and then flows out from the first water outlet 24; the water passage 22 is used to directly connect the first water inlet 23 and the first water outlet 24 when communicating with the first water inlet 23 and the first water outlet 24; the switching device is arranged in the water passage chamber 27, and the switching device is used to switch between the water passage 22 and the filtration channel 21, and communicate with the first water inlet 23 and the first water outlet 24; the filter element 50 can be detachably installed on the filter element socket 10.

[0057] In the technical solution provided by the utility model, a filter channel 21 and a water passage channel 22 are arranged in the water passage chamber 27 of the socket body 20, and then one of the water passage channel 22 and the filter channel 21 is switched through the switching device to be connected with the first water inlet 23 and the first water outlet 24, so that water flowing into the first water inlet 23 can be introduced into the filter element 50 through the filter channel 21 for filtration, and then flow out from the first water outlet 24, or directly flow out from the first water outlet 24 through the water passage channel 22. When the filter element 50 is normal, the filter channel 21 is switched through the switching device to be connected with the first water inlet 23 and the first water outlet 24. When the filter element 50 is dirty and blocked, the water passage channel 22 is switched through the switching device to be connected with the first water inlet 23 and the first water outlet 24, thereby avoiding blocking the waterway when the filter element 50 is dirty and blocked, affecting the flow of the entire water supply system.

[0058] In order to achieve synchronous rotation of the filter element 50 and the valve core 30, the switching device includes a valve core 30, and the valve core 30 can be rotatably installed in the water passage chamber 27.
