[0038] In order to meet the needs of users, many current refrigerators are equipped with a water supply system, which provides water for some functions in the refrigerator, such as ice making, through an external water source. A filter element assembly is generally provided in the water supply system, and the filter element assembly includes a filter element seat and a detachable filter element. A bent pipe is fixedly installed on the filter element seat. During the process of installing or removing the filter element, the bent pipe installed on the filter element seat and the filter element seat may rotate or shake relative to each other, thereby pulling the bent pipe and affecting the overall stability of the water supply system.

[0039] In order to solve the above problems, the utility model provides a filter element socket and a filter element assembly.

[0040] See also Figures 1 to 9 The filter element socket 10 includes a socket body 20, at least one water receiving pipe 30 and a limiting structure 40. A water passage 21 and a mounting channel 22 connected to the end of the water passage 21 are formed in the socket body 20; one end of the water receiving pipe 30 is mounted on the mounting channel 22 and is rotatably connected to the end of the water passage 21; the limiting structure 40 is used to limit the water receiving pipe 30 along the length direction of the mounting channel 22 to prevent the water receiving pipe 30 from falling out of the mounting channel 22.

[0041] In the technical solution provided by the utility model, the water receiving pipe 30 is connected with the water flow channel 21 in the socket body 20 by rotation, so that the water receiving pipe 30 and the socket body 20 can rotate relative to each other. During the installation or removal of the filter element 50, the water receiving pipe 30 and the socket body 20 can rotate relative to each other, thereby avoiding the phenomenon of pulling the water receiving pipe 30 caused by the fixed connection between the two, thereby improving the stability of the filter element assembly 100. In addition, since the water receiving pipe 30 is connected with the end of the water flow channel 21 by rotation, it is easy to produce the phenomenon of escaping from the installation channel 22. In this regard, in the technical solution of the present application, the limiting structure 40 is provided to limit the water receiving pipe 30 along the length direction of the installation channel 22 to prevent the water receiving pipe 30 from escaping from the installation channel 22.

[0042] It should be noted that the installation channel 22 may be provided with one or more, and the water receiving pipe 30 may be provided with one or more, which is not limited here. For example, the installation channel 22 may be provided with three, and the water receiving pipe 30 may be provided with one, two, three, etc., which is not limited here. The water receiving pipe 30 may be a water inlet pipe or a water outlet pipe. Of course, the water receiving pipe 30 may also be provided with two, one of which is a water inlet pipe and the other is a water outlet pipe, which is not limited here. When the water receiving pipe 30 is provided with two, one of which is a water inlet pipe and the other is a water outlet pipe, water flows from the water inlet pipe into one end of the water passage 21, and then flows out from the other end of the water passage 21 into the water outlet pipe. In the water passage 21, the water may be purified by the filter element 50, or the water outlet pipe and the water inlet pipe may be directly connected, which is not limited here.

[0043] See also Figures 1 to 4The water receiving pipe 30 and the end of the water passage 21 are connected in rotation, which can be achieved by directly connecting the water receiving pipe 30 and the end of the water passage 21, or by a movable sleeve connection, or by a bearing connection, etc. It only needs that the water receiving pipe 30 and the socket body 20 can rotate relative to each other, which is not limited here. The relative rotation between the water receiving pipe 30 and the socket body 20 can be that the socket body 20 rotates and the water receiving pipe 30 does not move, or that the socket body 20 does not move and the water receiving pipe 30 rotates. Of course, it can also be that both the water receiving pipe 30 and the socket body 20 rotate, which is not limited here.

[0044] The specific implementation of the limiting structure 40 is not limited, and can be in the form of a slot 46 and a block 47, or in the form of a latch and a block, etc., which is not limited here.

[0045] In one embodiment, the limiting structure 40 includes a limiting portion disposed in the installation channel 22 and a matching portion disposed on the water receiving pipe 30 , and the limiting portion and the matching portion are matched to limit the water receiving pipe 30 .

[0046] In the technical solution of this embodiment, by providing the limiting portion and the matching portion, when the water receiving pipe 30 has a tendency to move out of the installation channel 22, interference occurs between the limiting portion and the matching portion, thereby limiting the water receiving pipe 30 and preventing it from falling out of the installation channel 22.

[0047] Specifically, the specific implementation form of the limiting portion and the matching portion is not limited. For example, it can be a combination of a slot 46 and a block 47. For example, the limiting portion is a slot 46 and the matching portion is a block 47. Of course, the limiting portion can also be a block 47 and the matching portion can be a slot 46. By analogy, it can also be a combination of an insert block and a slot, or a combination of an abutment block and an abutment protrusion 42, etc., which are not limited here. Taking the cylindrical installation channel 22 as an example, as long as it can be rotated in the circumferential direction of the installation channel 22 and positioned in the axial direction.

[0048] Furthermore, in one embodiment, the limiting portion includes a groove 41, and the matching portion includes a protrusion 42. In the technical solution of this embodiment, a groove 41 is formed on the inner wall of the installation channel 22, and a protrusion 42 is formed on the outer wall of the water receiving pipe 30. After the water receiving pipe 30 is installed, the groove 41 and the protrusion 42 cooperate to position the water receiving pipe 30 in the length direction of the installation channel 22. In addition, in order to prevent the groove 41 from limiting the water receiving pipe 30 in the rotation direction, the groove 41 is extended along the circumference of the water receiving pipe 30, so that when the water receiving pipe 30 rotates in the circumferential direction, the water receiving pipe 30 is not limited, but when it moves in the axial direction, it is limited to prevent it from falling out.

[0049] There are many ways to form the groove 41. The groove 41 may be directly opened on the inner wall of the installation channel 22, or a plurality of components may be arranged at intervals to form the groove 41, and so on. No limitation is made here. Considering the assembly problem of the filter element socket 10, the method of directly opening the groove 41 may cause the protrusion 42 to interfere with the inner wall of the installation channel 22 during the installation of the water receiving pipe 30, resulting in a problem of great difficulty in assembly.

[0050] Therefore, in one embodiment, the socket body 20 is provided with a step 44 at the installation channel 22 , and the filter element socket 10 further includes a stop block provided in the installation channel 22 , and the stop block and the step 44 jointly define the groove 41 .

[0051] In the technical solution of this embodiment, during assembly, the water receiving pipe 30 is first assembled into the installation channel 22, so that one side of the protrusion 42 abuts against the step 44, and then the stop block 43 is installed into the installation channel 22 and abuts against the other side of the protrusion 42, and finally the stop block 43 is fixedly connected to the channel wall of the installation channel 22, and the assembly of the water receiving pipe 30 is completed, reducing the difficulty of assembly.

[0052] It should be noted that the method of fixing the stop block 43 and the channel wall of the installation channel 22 is not limited, and can be bonding, screw connection, riveting, welding, etc. Considering the need for certain sealing and waterproof properties, in one embodiment, the stop block 43 and the channel wall of the installation channel 22 are connected by welding.

[0053] Furthermore, in order to improve the limiting effect and stability, the water receiving pipe 30 includes a first pipe section 31 and a second pipe section 32 connected to each other, wherein the first pipe section 31 is used to be installed to the installation channel 22, and the protrusion 42 is arranged on the outside of the first pipe section 31, and the stop block 43 is arranged on the outside of the first pipe section 31 and abuts against the protrusion 42. In the technical solution of this embodiment, the stop block 43 is arranged on the outside of the first pipe section 31. On the one hand, when the protrusion 42 is rotated to any position, the protrusion 42 can be limited, thereby improving the limiting effect and stability.

[0054] Taking into account that the water receiving pipe 30 is arranged in two sections, the annular stop block 43 is difficult to install. Therefore, in order to simplify the installation process, the second pipe section 32 corresponding to the stop block 43 is provided with an avoidance gap 45. In the technical solution of this embodiment, by providing the avoidance gap 45, during the installation process, when the stop block 43 is installed toward the installation channel 22, the avoidance gap 45 can avoid the second pipe section 32, thereby avoiding interference between the stop block 43 and the second pipe section 32 during the installation process.

[0055] Of course, in order to prevent the protrusion 42 from escaping from the avoidance gap 45 , the width of the protrusion 42 is greater than the width of the avoidance gap 45 .

[0056] See also Figures 5 to 9 Of course, in other embodiments, the matching portion includes a slot 46 arranged on the water receiving pipe 30, and the slot 46 is extended along the circumference of the water receiving pipe 30, and the limiting portion includes a block 47. In this embodiment, the slot 46 is extended along the circumference of the water receiving pipe 30, so that when the water receiving pipe 30 rotates along the circumference, there will be no interference between the slot 46 and the block 47.

[0057] When the water receiving pipe 30 is about to move in the length direction of the installation channel 22, the clamping groove 46 will interfere with the clamping block 47 to prevent the movement.

[0058] Furthermore, in order to facilitate the assembly of the water receiving pipe 30 and avoid interference between the block 47 and the slot 46 during the assembly process, the socket body 20 is provided with a mounting groove 23 corresponding to the slot 46, and the block 47 is installed in the mounting groove 23 and at least partially extends into the slot 46. In the technical solution of this embodiment, by providing the mounting groove 23 corresponding to the slot 46 on the socket body 20, the water receiving pipe 30 can be installed first during the assembly process, and then the block 47 can be installed, thereby avoiding interference of the block 47 with the water receiving pipe 30 during the installation process.

[0059] At the same time, in order to improve the limiting effect, the card block 47 includes a first card segment 48 and a second card segment 49 that are relatively arranged, and a connecting part connecting the first card segment 48 and the second card segment 49, and the first card segment 48 and the second card segment 49 jointly clamp the card slot 46. In this embodiment, by setting the card block 47 with the first card segment 48 and the second card segment 49, the first card segment 48 and the second card segment 49 jointly clamp the card slot 46, thereby improving the limiting effect of the card slot 46.

[0060] Furthermore, by providing the first clamping section 48 and the second clamping section 49 , a gap is formed between the two clamping sections, that is, the clamping block 47 is provided in a U-shape, which can facilitate the installation of the water receiving pipe 30 .

[0061] At the same time, in order to prevent the water in the water inlet channel from overflowing from the installation channel 22, the filter element seat 10 also includes a first sealing member 11, which is sleeved on the water receiving pipe 30 and abuts against the installation channel 22. In this way, the first sealing member 11 can block the gap between the water receiving pipe 30 and the installation channel 22 to prevent water from overflowing from the installation channel 22.

[0062] Specifically, the specific implementation form of the first sealing member 11 is not limited, and may be a sealing ring or an annular waterproof material to seal the gap between the water receiving pipe 30 and the installation channel 22 .

[0063] In the solution in which the mounting groove 23 is provided, the first sealing member 11 is provided between the mounting groove 23 and the water inlet channel, so as to prevent water from flowing out of the mounting groove 23 .

[0064] Of course, in order to further improve the sealing effect, the first sealing member 11 is arranged close to the water inlet channel, so as to effectively seal the water flowing from the water inlet channel into the installation channel 22 .

[0065] To achieve the above-mentioned purpose, the present application also proposes a filter element assembly 100, including a filter element socket 10 and a filter element 50, the filter element socket 10 includes a socket body 20, at least one water receiving pipe 30 and a limiting structure 40, a water flow channel 21 and an installation channel 22 connected to the end of the water flow channel 21 are formed in the socket body 20; one end of the water receiving pipe 30 is installed in the installation channel 22 and is rotatably connected to the end of the water flow channel 21; the limiting structure 40 is used to limit the water receiving pipe 30 along the length direction of the installation channel 22 to prevent the water receiving pipe 30 from escaping from the installation channel 22, and the filter element 50 is installed in the filter element socket 10.

[0066] In the filter element assembly 100 provided by the present invention, the water receiving pipe 30 can rotate relative to the socket body 20 and will not fall out of the installation channel 22. The water receiving pipe 30 is connected to the water flow channel 21 in the socket body 20 by rotation, so that the water receiving pipe 30 and the socket body 20 can rotate relative to each other. During the installation or removal of the filter element 50, the water receiving pipe 30 and the socket body 20 can rotate relative to each other, thereby avoiding the phenomenon of pulling the water receiving pipe 30 caused by the fixed connection between the two, thereby improving the stability of the filter element assembly 100. In addition, since the water receiving pipe 30 is connected to the end of the water flow channel 21 by rotation, it is easy to fall out of the installation channel 22. In this regard, in the technical solution of the present application, the limiting structure 40 is provided to limit the water receiving pipe 30 along the length direction of the installation channel 22 to prevent the water receiving pipe 30 from falling out of the installation channel 22.
