However, when the filter is removed, the water inlet and outlet of the bypass seat are disconnected, so that the water system cannot be connected, making the water supply system of the refrigeration equipment unusable. Summary of the invention

[0057] The bypass seat provided by the present invention comprises a seat 1 and a switching member 2, wherein the seat 1 is provided with a first water inlet 10 and a first water outlet 12, the switching member 2 is provided with a first channel 20, and the switching member 2 is arranged in the seat 1 and rotatably connected to the seat 1 to realize the switching of the path connected between the first water inlet 10 and the first water outlet 12. Figure 3 As shown, when the switching member 2 is in the second position, one end of the first channel 20 is connected to the first water inlet 10, and the first water outlet 12 is connected to the other end of the first channel 20. At the same time, the first channel 20 can be connected to the filter 7, so that the liquid flows from the first water inlet 10 into one end of the first channel 20, flows into the filter 7 through the first channel 20, and then flows from the other end of the first channel 20 to the first water outlet 12 after being filtered by the filter 7, thereby achieving the filtration of the liquid and improving the water quality; Figure 4 As shown, when the switching member 2 is in the first position, the first channel 20 on the switching member 2 cannot connect the first water inlet 10 and the first water outlet 12, so that the liquid flowing into the first water inlet 10 cannot flow into the first channel 20, thereby avoiding water leakage from the first channel 20 when the filter 7 is pulled out, and the outer surface of the switching member 2 and the inner wall surface of the seat body 1 enclose the second channel 3, and the first water inlet 10 is connected with the first water outlet 12 through the second channel 3, so that the liquid can still be transported, ensuring the smooth flow of the waterway. The bypass seat body proposed in the present application realizes the switching of the connecting channel between the first water inlet 10 and the first water outlet 12 through the movement of the switching member 2, which can not only realize the purification of the liquid, but also ensure the smooth flow of the waterway. In addition, the connection between the first water inlet 10 and the first water outlet 12 is realized through the outer surface of the switching member 2, and there is no need to set a through channel on the switching member 2 to realize the connection between the first water inlet 10 and the first water outlet 12, which simplifies the manufacturing difficulty of the switching member 2, facilitates the mold forming of the switching member 2, and reduces the manufacturing cost. In addition, the switching of the connecting channel can be realized by the rotation of the switching member 2, and there is no need to set up an additional movement space for the switching member 2, which improves the space utilization inside the seat body 1.

[0058] Optionally, the switching element 2 rotates around its own rotation axis.

[0077] It can be understood that the first trough 21 and the second trough 22 are also arranged on the switching column 23. In the assembled state, the end of the first channel 20 connected to the first water inlet 10 is also the second water inlet 202, and the end of the first channel 20 connected to the first water outlet 12 is also the third water outlet 208.

[0081] like Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, according to one embodiment of the present invention, a water purification component is also proposed, including: a filter 7; and a bypass seat body as proposed in any of the above items, when the switching member 2 is in the second position, the first channel 20 is connected to the filter 7, so that the first water inlet 10 is connected to the first water outlet 12 through the filter 7.

[0082] The water purification component provided by the present invention comprises the bypass seat body provided in any of the above embodiments, and therefore has all the beneficial effects of the bypass seat body.

[0083] Specifically, Figure 3 , Fig.12 and Fig.13 As shown, when the switching member 2 is in the second position, one end of the first channel 20 is connected to the first water inlet 10, and the first water outlet 12 is connected to the other end of the first channel 20. At the same time, the first channel 20 can be connected to the filter 7, so that the liquid flows from the first water inlet 10 into one end of the first channel 20, flows into the filter 7 through the first channel 20, and then flows from the other end of the first channel 20 to the first water outlet 12 after being filtered by the filter 7, thereby achieving the filtration of the liquid and improving the water quality (the direction of the water flow is shown in FIG. 1 ). Fig.12 as indicated by the arrow direction); Figure 4 As shown, when the switching member 2 is in the first position, the first channel 20 on the switching member 2 cannot communicate with the first water inlet 10 and the first water outlet 12, so that the liquid flowing into the first water inlet 10 cannot flow into the first channel 20, thereby preventing water leakage from the first channel 20 when the filter 7 is pulled out, and the outer surface of the switching member 2 and the inner wall surface of the seat body 1 enclose the second channel 3, and the first water inlet 10 is connected with the first water outlet 12 through the second channel 3 (the water flow direction is as shown in FIG. Figure 4 As shown by the arrow, the liquid can still be transported, ensuring the smooth flow of water.

[0084] In some embodiments, the filter 7 is optionally detachably connected to the bypass seat.

[0085] In this embodiment, the filter 7 is detachably connected to the bypass seat body, so that when the filter element 72 of the filter 7 reaches a predetermined usage time or reaches its service life, the filter 7 can be removed and the filter element 72 can be replaced to ensure the reliability of the water purification system.

[0086] Optionally, the filter 7 is detachably connected to the seat body 1, so that the filter 7 has an assembled state and a disassembled state. During the switching process between the assembled state and the disassembled state, the filter 7 can cooperate with the switching member 2 to drive the switching member 2 to rotate between the first position and the second position. During the assembly process of the filter 7, the filter 7 drives the switching member 2 to rotate to the second position, and during the removal process of the filter 7, the filter 7 moves relative to the seat body 1, thereby driving the switching member 2 to switch to the first position.

[0087] For example, a first limit portion 26 is provided on the switching member 2, and a second limit portion 78 is provided on the filter 7. During the switching process of the filter 7 between the assembled state and the disassembled state, the first limit portion 26 and the second limit portion 78 can cooperate in a limited manner so that the filter 7 drives the switching member 2 to rotate between the first position and the second position.

[0088] In this embodiment, a first limiting portion 26 is provided on the switching member 2, and a second limiting portion 78 is provided on the filter 7. During the disassembly and assembly of the filter 7 and the seat body 1, the first limiting portion 26 and the second limiting portion 78 are limitedly cooperated, thereby driving the switching member 2 to rotate between the first position and the second position, thereby realizing the switching of the liquid flow path.

[0089] Optionally, when the filter 7 includes a bottle body 70 , a filter element 72 and a water stopper 74 , the second limiting portion 78 is disposed on the bottle body 70 or the water stopper 74 .

[0090] like Fig.12 , Fig.13 and Fig.14 As shown, in some embodiments, optionally, the filter 7 includes: a bottle body 70, the bottle body 70 is provided with an opening, and the bottle body 70 is detachably connected to the seat body 1; a filter element 72, which is arranged in the bottle body 70; a water stop member 74, which is provided at the opening and encloses a water stop gap 76 with the inner wall surface of the opening, and a third channel 740 is provided on the water stop member 74, and the water stop gap 76 is connected to the third channel 740 through the filter element 72; when the filter 7 is connected to the seat body 1 and the switching member 2 is in the second position, the second water outlet 204 of the first channel 20 is connected to the water stop gap 76, and the third water inlet 206 of the first channel 20 is connected to the third channel 740; when the filter 7 is separated from the seat body 1, a water film can be formed in the water stop gap 76.

[0091] In this embodiment, the filter 7 includes a bottle body 70, a filter element 72 and a water stop member 74. The filter element 72 is arranged in the bottle body 70 for filtering liquid. The water stop member 74 is arranged in the bottle body 70 and is located at one end of the filter element 72. The water stop member 74 and the inner wall surface of the opening enclose a water stop gap 76. At the same time, a third channel 740 is arranged on the water stop member 74. When the filter 7 is connected to the seat body 1, the liquid flowing into the seat body 1 from the first water inlet 10 passes through the second water inlet 202, the second water outlet 204 and the water stop gap 76 in sequence and enters the bottle body 70. After being filtered by the filter element 72, the liquid flows from the third channel 740 to the third water inlet 206, and then flows from the third water outlet 208 to the first water outlet 12, thereby achieving liquid purification. When the filter 7 is separated from the seat 1, the water in the water-stop gap 76 forms a water film due to surface tension, thereby preventing external air from entering the bottle body 70, so that the liquid in the bottle body 70 does not flow out, reducing the amount of dripping when replacing the filter 7.

[0092] Optionally, the width of the water-stop gap 76 is greater than 0 mm and less than or equal to 1 mm, so as to ensure that water can form a water film in the water-stop gap 76 due to the effect of tension, thereby avoiding water-stop failure.

[0093] Optionally, in order to prevent the water stop gap 76 from increasing due to local shrinkage during the injection molding process, a reinforcing rib 741 is provided on the water stop member 74 .

[0094] Specifically, Fig.15 As shown, the water stop 74 is an injection molded part, wherein a cavity is provided between the outer wall of the injection molded part and the third channel 740, the cavity is provided around at least part of the circumference of the third channel 740, and a reinforcing rib 741 is provided in the cavity. This arrangement can not only reduce the amount of material through the arrangement of the cavity, but also improve the structural strength of the injection molded part through the arrangement of the reinforcing rib 741, thereby avoiding the problem of excessive shrinkage caused by excessive amount of material, excessive thickness and low structural strength during the molding process of the injection molded part, and further avoiding the occurrence of an excessively large water stop gap 76, thereby ensuring the size of the water stop gap 76 to improve the reliability of the water stop function of the water stop gap 76.

[0095] Optionally, the water stop member 74 includes: a cover body 743, which is arranged in the bottle body 70 and is limitedly engaged with the bottle body 70, the cover body 743 is located at the end of the filter element 72 close to the opening, there is a gap between the cover body 743 and the bottle body 70, and the gap is connected to the water stop gap 76; a water stop portion 744, which is arranged in the cover body 743 and protrudes from the side of the cover body 743 close to the opening, and the outer wall of the water stop portion 744 and the bottle body 70 enclose a water stop gap 76; a connecting portion 745, which is arranged at the end of the water stop portion 744 close to the opening, the third channel 740 runs through the water stop portion 744, the connecting portion 745 and the cover body 743, and an installation cavity is enclosed between the connecting portion 745 and the bottle body 70, and the installation cavity is connected to the water stop gap 76; in the assembled state, a part of the switching member 2 extends into the installation cavity.

[0096] In this embodiment, the water stop member 74 includes a cover body 743, a water stop portion 744 and a connection portion 745 arranged on the cover body 743, the water stop portion 744 is arranged on the cover body 743 and protrudes from the side of the cover body 743 close to the opening, the connection portion 745 is arranged on the side of the water stop portion 744 close to the opening, the outer wall of the water stop portion 744 and the inner wall surface of the bottle body 70 enclose a water stop gap 76, and the connection portion 745 and the bottle body 70 enclose a mounting cavity. When the filter 7 is installed on the seat body 1, a part of the switching member 2 is inserted into the mounting cavity, so that the first water inlet 10 is connected to the filter part through the water stop gap 76, and the third channel 740 is connected to the third water inlet 206, so that the liquid flowing into the first water inlet 10 can flow through the filter part and then flow out from the first water outlet 12, so as to achieve the effect of liquid filtering. After the filter 7 is removed, the water stop gap 76 can achieve water stopping of the filter 7 and prevent the bottle body 70 from leaking. At the same time, there is a gap between the cover body 743 and the bottle body 70, so that the liquid flowing into the water-stop gap 76 flows to the filter part through the gap, thereby realizing the filtration of the liquid. In addition, the cover body 743 and the bottle body 70 are limited by cooperation, which can fix the position of the water-stop part 74, thereby ensuring the reliability of water-stopping of the water-stop gap 76.

[0097] Alternatively, if Fig.16 As shown, a slit 742 is provided on the water stop portion 744 , and the slit 742 penetrates the water stop portion 744 along the axial direction of the switching member 2 , and the slit 742 is connected to the water stop gap 76 to increase the water flow area and reduce the risk of blockage.

[0098] Optionally, when the filter 7 is connected to the seat body 1 , the third channel 740 extends into the connecting shell 24 and communicates with the third water inlet 206 .

[0099] like Fig.17 As shown, according to an embodiment of the present invention, a refrigeration device 8 is also proposed, including: and a water purification component as proposed in any one of the above items.

[0100] The refrigeration device 8 provided by the present invention comprises the water purification component proposed in any of the above embodiments, and therefore has all the beneficial effects of the water purification component.

[0101] like Fig.17 As shown, in some embodiments, optionally, the refrigeration equipment 8 also includes: a first refrigeration chamber 80, the first refrigeration chamber 80 is provided with a water outlet 800; a second refrigeration chamber 82, the second refrigeration chamber 82 is provided with an ice-making section 820, and the first water outlet 12 is connected to the water outlet 800 and the ice-making section 820, and is used to supply water to the water outlet 800 and the ice-making section 820.

[0102] In this embodiment, the refrigeration equipment 8 also includes a first refrigeration chamber 80 and a second refrigeration chamber 82. The first refrigeration chamber 80 is provided with a water outlet 800, and the second refrigeration chamber 82 is provided with an ice-making section 820. The first water outlet 12 is respectively connected to the water outlet 800 and the ice-making section 820, so that the liquid flows to the water outlet 800 and the ice-making section 820, respectively, to prepare cold water and ice cubes.

[0103] Optionally, the first refrigerating chamber 80 includes a refrigerator compartment, and the second refrigerating chamber 82 includes a freezer compartment.

[0104] Optionally, the refrigeration equipment 8 also includes a valve body, which is arranged at the first water outlet 12 and is used to switch the connection direction of the first water outlet 12 so that the first water outlet 12 is connected to the water outlet part 800 and / or the first water outlet 12 is connected to the ice making part 820.

[0105] Specifically, the first water inlet 10 is connected to a water supply unit, such as an external faucet or a water tank assembly. When the filter 7 is installed on the base 1, the liquid flows from the first water inlet 10 to the filter 7, and after being filtered by the filter 7, flows out from the first water outlet 12, and then flows to the water outlet 800 and / or the ice making unit 820 under the switching of the valve body.

[0106] Optionally, the refrigeration equipment 8 includes a refrigerator, a freezer, etc.

[0107] In a specific application, the water purification component includes a fixing seat, a connection seat (such as a bypass seat body), and a water purification module (such as a filter 7). The water purification module is connected to the connection seat by a rotating installation.

[0108] The socket is composed of a socket body (such as a socket body 1), a rotating center rod, a welded fixing ring (such as a fixing ring 6), a water inlet joint, a water outlet joint and a plurality of sealing rings, and the assembly is completed by an ultrasonic welding process. The water purification module is composed of an upper end cover (such as a water stop 74), a filter material (such as a filter element 72), a lower end cover, a filter bottle (such as a bottle body 70) and a tail. Optionally, the water purification module also includes a handle, and the filter bottle and the tail are completed by rotation welding.

[0109] The water inlet joint (e.g., the first water inlet 10) and the water outlet joint (e.g., the first water outlet 12) of the socket are connected to the water inlet pipe and the water outlet pipe respectively. When the filter 7 is not installed, the water inlet and outlet of the rotating center rod (e.g., the second water inlet 202 and the third water outlet 208) are staggered at an angle with the water inlet and outlet of the socket body (e.g., the first water inlet 10 and the first water outlet 12), and the sealing ring (e.g., the second sealing ring 5) forms a seal between the water inlet and outlet of the rotating center rod and the inner wall of the socket body, so that water cannot flow into the rotating center rod. At this time, the water flowing into the socket from the water inlet joint flows into the water outlet joint through the structural steps and gaps (e.g., the first sink 21 and the second sink 22) between the rotating center rod and the socket body, forming a water flow path.

[0110] When the water purification module is assembled with the socket, the long arm at the bottom of the rotating center rod extends into the corresponding notch structure of the upper end cover. When the water purification module is rotated and fastened with the socket, because the upper end cover and the water purification module are fixedly connected, the water purification module will drive the rotating center rod inside the socket to rotate a certain angle, so that the water inlet and outlet of the rotating center rod are connected with the water inlet and outlet of the socket. Among them, the rotation angle of the rotating center rod can be adjusted by adjusting the width of the notch structure and the width of the long arm at the bottom of the rotating center rod, so as to realize a design in which the rotation angle of the rotating center rod and the water purification module are the same or different.

[0111] When the water purification module reaches the end of its service life or is disassembled midway, the notch structure of the upper end cover drives the long arm at the bottom of the rotating center rod to rotate in the opposite direction by the same angle, thereby restoring the rotating center rod to the position where the bypass channel is formed.

[0112] Optionally, regarding the implementation method of the rotation of the rotating center rod, the long arm at the bottom of the rotating center rod can also extend into a specific structure at the mouth of the filter bottle, and through the limiting cooperation between the two, the filter 7 drives the rotating center rod to rotate during disassembly and assembly.

[0113] Optionally, the upper end cover is assembled with the filter bottle, and the assembly gap between the upper end cover and the filter bottle (such as the water-stop gap 76) is controlled within 1 mm, so that when the water purification module is removed, water forms a water film in the narrow gap due to the surface tension of the water.

[0114] Optionally, in order to avoid the problem of water-stop failure caused by the local size of the water-stop gap 76 being too large due to local shrinkage in the injection molding process, the upper end cover may be reinforced.

[0115] Alternatively, if Fig.16 As shown, in addition to controlling the assembly gap between the upper end cap and the filter bottle to be within 1 mm, a slit (such as slit 742) with a gap within 1 mm can also be designed on the upper end cap to increase the water flow area and prevent clogging in actual use.

[0116] Optionally, in order to adapt to the two scenarios of refrigerator compartment and horizontal installation, a detachable handle is designed at the tail of the filter 7. When the filter 7 is installed on the top or door of the refrigerator compartment, the filter 7 and the socket are rotated and installed. At this time, the tail of the bottle body of the filter 7 can be grasped without using a handle. When the filter 7 is installed horizontally, the user has no other contact position. In this scenario, the filter 7 is equipped with a handle, and disassembly and assembly are achieved by grasping the handle. Optionally, the installation of the handle and the tail of the filter 7 can be achieved by snapping, socketing or welding, which can achieve lean manufacturing and realize differentiated usage scenarios with minimal material changes.

[0117] The water purification component proposed in the present application drives the rotating center rod to rotate during the installation process of the water purification module, thereby realizing the switching from the bypass channel to the purification channel without the need for additional operations, thus saving time and effort.

[0118] Optionally, the long arm is on the rotating central rod, and the notch structure is arranged on the water purification module, and the positions can also be reversed. At the same time, the number of sleeve positions between the rotating central rod and the water purification module should be no less than one.

[0119] Optionally, the notch structure may also be a groove or the like.
