[0002] In the related art, when the filter of the water purification assembly is installed in the seat body, the filter is in communication with the water channel in the seat body, thereby realizing the filtration of liquid. When the filter is disassembled, the water inlet and the water outlet of the seat body are disconnected, so that the water channel of the seat body cannot be communicated. If the communication of the water channel of the seat body is to be realized, a matched plug needs to be provided, so that the switching of the water channel of the seat body is time-consuming and laborious. SUMMARY

[0003] The present application aims to at least solve one of the problems existing in the prior art or the related art.

[0004] To this end, a first aspect of the present application provides a water purification assembly.

[0005] A second aspect of the present application further provides a refrigeration equipment.

[0006] Therefore, the first aspect of the present application provides a water purification assembly, which comprises a seat body provided with a first water inlet and a first water outlet; a switching piece arranged in the seat body and rotationally connected with the seat body, the switching piece being provided with a first channel; and a filter detachably connected with the seat body, so that the filter has an assembled state and a disassembled state. In the process of switching between the assembled state and the disassembled state, the filter can be limited to cooperate with the switching piece to drive the switching piece to rotate between a first position and a second position. When the filter is in the assembled state, the switching piece is located at the second position, one end of the first channel is in communication with the first water inlet, the other end of the first channel is in communication with the first water outlet, and the first channel is in communication with the filter. When the filter is in the disassembled state, the switching piece is located at the first position, the two ends of the first channel are arranged in a staggered manner with the first water inlet and the first water outlet, the surface of the switching piece and the inner wall surface of the seat body enclose a second channel, and the first water inlet is in communication with the first water outlet through the second channel.

[0007] The water quality purification assembly provided by the application comprises a seat body, a switching piece and a filter. The seat body is provided with a first water inlet and a first water outlet. The switching piece is provided with a first channel. The switching piece is arranged in the seat body and is rotationally connected with the seat body. The filter is detachably connected with the seat body. During the process of detaching the filter from the seat body, the filter can drive the switching piece to rotate between a first position and a second position, so as to switch the path connected between the first water inlet and the first water outlet. During the process of assembling the filter, the filter drives the switching piece to rotate to the second position. When the switching piece is located at the second position, one end of the first channel is communicated with the first water inlet, the first water outlet is communicated with the other end of the first channel, and the filter is communicated with the first channel. Therefore, the liquid flowing into the seat body from the first water inlet flows into the filter through the one end of the first channel, and then flows to the first water outlet through the other end of the first channel after being filtered by the filter, and finally flows out of the seat body, so that the liquid is filtered and the water quality is improved. During the process of detaching the filter, the filter moves relative to the seat body, so as to drive the switching piece to switch to the first position. When the switching piece is located at the first position, the first channel on the switching piece cannot be communicated with the first water inlet and the first water outlet, so that the liquid flowing into the first water inlet cannot flow into the first channel, thereby avoiding the liquid leakage when the filter is pulled out. When the switching piece is located at the first position, the outer surface of the switching piece and the inner wall surface of the seat body enclose a second channel. The first water inlet is communicated with the first water outlet through the second channel, so that the liquid can still be conveyed when the filter is pulled out, thereby ensuring the reliability of liquid conveying. The water quality purification assembly provided by the application can drive the switching piece to move when the filter is assembled or detached, so that the movement of the switching piece does not need to be driven by other driving structures, the number of parts is reduced, the overall volume of the water quality purification assembly is reduced, and when the filter is detached, the first water inlet and the first water outlet are communicated through the outer surface of the switching piece, so that a through channel does not need to be arranged on the switching piece to realize the communication between the first water inlet and the first water outlet, the manufacturing difficulty of the switching piece is simplified, the mold forming of the switching piece is facilitated, the manufacturing cost is reduced, and the switching of the communication channel can be realized by the rotation of the switching piece around the rotation axis of the switching piece, so that the movement space of the switching piece does not need to be additionally arranged, and the space utilization rate of the seat body is improved.

[0135] Optionally, the refrigeration device 8 further comprises a valve body arranged at the first water outlet 12 to switch the communication direction of the first water outlet 12, so as to make the first water outlet 12 communicate with the water outlet part 800 and / or make the first water outlet 12 communicate with the ice making part 820.

[0136] Specifically, the first water inlet 10 is in communication with a water supply part, such as an external water faucet or a water tank assembly. In the case that the filter 3 is in an assembled state, the liquid flows from the first water inlet 10 to the filter 3, and then flows out from the first water outlet 12 after being filtered by the filter 3, and then flows to the water outlet part 800 and / or the ice making part 820 under the switching of the valve body.

[0137] Optionally, as shown, Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, a structure schematic view of the switching piece 2 and the seat body 1 being mounted together is shown.

[0138] In a specific application, the water purification assembly comprises a fixing seat 7, a connector (containing water inlet and outlet), and a water purification module (such as a filter 3). The water purification module is connected to the connector by means of rotary installation.

[0139] As shown in Figures 11 to 16 , the connector is composed of a connector main body (such as a seat body 1), a rotary center rod (such as a switching piece 2), a welded fixing ring (such as a fixing ring 6), a water inlet connector (provided with a first water inlet 10), a water outlet connector (provided with a first water outlet 12), and a plurality of sealing rings, and the assembly is completed by ultrasonic welding process. The water purification module is composed of an upper end cover (such as a water stopping piece 32), filter material (such as a filter core 31), a lower end cover, a filter bottle (such as a bottle body 30), and a tail part. Optionally, the water purification module further comprises a handle 37, and the filter bottle and the tail part are completed by rotary welding.

[0140] The water inlet connector and the water outlet connector of the connector are connected to the water inlet pipe and the water outlet pipe respectively. When the filter 3 is not installed, the connector is as shown in Figure 7 . At this time, the water inlet and outlet of the rotary center rod (such as the second water inlet 2020 and the third water outlet 2042) are staggered at an angle (optionally, the angle is 90°) with the water inlet and outlet of the connector main body (such as the water inlet connector and the water outlet connector), and the sealing ring (such as the second sealing ring 5) forms a seal between the water inlet and outlet of the rotary center rod and the inner wall of the connector main body, so that water cannot flow into the rotary center rod. At this time, the water flowing into the connector from the water inlet connector flows into the water outlet connector through the structural steps and gaps (such as the first sink 21 and the second sink 22) between the rotary center rod and the connector main body, forming a water flow path.

[0141] As shown in Figure 22 , when the water purification module is assembled with the connector, the long arm (such as the first limiting part 29) at the bottom of the rotary center rod extends into the corresponding notch structure (such as the second limiting part 36) of the upper end cover. When the water purification module is rotated and buckled with the connector, because the upper end cover is fixedly connected with the water purification module, the water purification module will rotate the rotary center rod inside the connector by a certain angle, so that the water inlet and outlet of the rotary center rod and the water inlet and outlet of the connector are communicated. The width of the notch structure and the width of the long arm at the bottom of the rotary center rod can be adjusted to adjust the rotation angle of the rotary center rod, so as to realize the design that the rotation angle of the rotary center rod is the same as or different from that of the water purification module.

[0142] When the water purification module reaches the service life or is disassembled halfway, the notch structure of the upper end cover rotates the long arm at the bottom of the rotary center rod in the opposite direction by the same angle, so that the rotary center rod returns to the position forming the bypass channel.

[0143] Optionally, as for the implementation of the rotation of the rotating center rod, the long arm of the bottom of the rotating center rod can also extend into the specific structure of the filter bottle opening, and the filter 3 drives the rotating center rod to rotate through the limiting cooperation of the two during disassembly and assembly.

[0144] Optionally, as shown in Figure 6 The assembly gap between the upper end cover and the filter bottle (for example, the water stop gap 33) is controlled within 1 mm, so that when the water quality purification module is removed, a water film is formed in the gap due to the surface tension of the water.

[0145] Optionally, to avoid the problem of water stop failure caused by the local shrinkage of the injection molding process, the upper end cover can be reinforced.

[0146] Optionally, as shown in Figure 29 In addition to controlling the assembly gap with the filter bottle within 1 mm, a gap (for example, the slit 38) within 1 mm can also be designed on the upper end cover. To increase the water area, it is not easy to block in actual use.

[0147] Optionally, to adapt to the two scenarios of refrigeration chamber and horizontal installation, a detachable handle 37 is designed at the tail of the filter 3. When the filter 3 is installed on the top of the refrigeration chamber or the door body of the refrigerator, the filter 3 is rotatably installed with the socket, at this time, the bottle body tail of the filter 3 can be gripped, without the need to select the handle 37. When the filter 3 is installed horizontally, the user has no other contact position, and the filter 3 is equipped with the handle 37 in this scenario, and the handle 37 is gripped to realize disassembly and assembly. Optionally, the installation of the handle 37 and the tail of the filter 3 can be realized by buckling, sleeving or welding, which can realize lean manufacturing to minimize material changes to realize differentiated use scenarios.

[0148] The water quality purification assembly disclosed in the present application drives the rotating center rod to rotate during the installation process of the water quality purification module, realizes the switching of the bypass channel (for example, the channel formed by the first water inlet 10, the second channel 14 and the first water outlet 12) to the purification channel (for example, the channel formed by the first water inlet 10, the first channel 20, the filter 3 and the first water outlet 12), without the need for additional operation, saving time and effort.

[0149] Optionally, the long arm is on the rotating center rod, and the notch structure is arranged on the water quality purification module, or the positions can be transposed. At the same time, the number of the sleeving positions of the rotating center rod and the water quality purification module should be not less than 1.

[0150] Optionally, the notch structure can also be a groove, etc.
