Detailed implementation manners

[0042] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. It should be understood that the accompanying drawings of the present utility model are only for illustrative purposes, and it is understandable for those skilled in the art to omit some well-known structures and their descriptions in the drawings. At the same time, in the description of the present utility model, if there are descriptions of terms such as "upper", "lower", "left", "right" indicating the orientation or positional relationship, it is only based on the orientation or positional relationship shown in the accompanying drawings, and is for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Correspondingly, in the description of the present utility model, if there are descriptions such as "first", "second", etc., such descriptions are only used to distinguish different components, and cannot be understood as indicating or implying their relative importance, any order or implicitly indicating the quantity of the indicated technical features.

[0043] In the related art, a refrigerator with a water dispenser function generally includes a water kettle and a liquid extraction mechanism for extracting water from the water kettle. The water kettle is installed inside the refrigerator door, and the water kettle has a water outlet. The liquid extraction mechanism is installed outside the refrigerator door. The liquid extraction mechanism includes a water outlet nozzle and a pressing tongue. The refrigerator door has a door hole. One end of the water outlet nozzle is connected to the water outlet of the water kettle through the door hole, and the other end of the water outlet nozzle extends out of the door hole and is connected to the pressing tongue. The pressing tongue is rotatably arranged on the door. The user presses the pressing tongue to control the water outlet nozzle to act on the water outlet to open or close the water outlet, so as to realize the user's water extraction.

[0044] To reduce the leakage of the liquid in the water kettle from the assembly position of the water outlet of the water kettle and the door hole, the related art usually glues a seal in the door hole to seal the gap between the water outlet of the water kettle and the door hole. However, during the user's water extraction process, the liquid often flows between the water outlet of the water kettle and the door hole, resulting in the glue layer fixing the seal being loosened or falling off due to long-term immersion in the liquid, resulting in poor sealing between the water outlet of the water kettle and the door hole of the refrigerator door, and still often causing liquid residue. The residual liquid here is likely to pollute the environment inside the refrigerator and affect the hygiene of the taken ice water, requiring the user to clean repeatedly, resulting in a poor user experience.

[0045] Therefore, the present utility model provides a sealing assembly 30, which is used to improve the sealing performance between the liquid outlet hole 13 of the liquid storage device 10 and the refrigerator door 40 of the refrigerator 1, thereby reducing the liquid residue at the assembly position between the liquid outlet hole 13 of the liquid storage device 10 and the refrigerator door 40, so as to maintain the environmental hygiene inside the refrigerator and the hygiene of the user's water extraction, and reduce the workload of the user's repeated cleaning, and improve the user experience.

[0046] In addition, the sealing assembly 30 provided by the present utility model is not limited to being used on the refrigerator door 40 of the refrigerator 1. The sealing assembly 30 can also be arranged between the water bucket of the water dispenser and the water dispenser body, or the sealing assembly 30 can be externally connected to other pipelines to improve the sealing performance at the assembly position of the externally connected pipelines and reduce the leakage of fluids such as liquids or gases.

[0047] Next, the sealing assembly 30 provided by the present utility model will be described.

[0048] Please refer to Figures 1 to 3, the present utility model provides a sealing assembly 30, which includes a conduit 31, a seal 32 and a sleeve 33. The conduit 31 has an inlet connection end 31a and an outlet connection end 31b arranged oppositely. The sleeve 33 is fixed on the outer wall of the conduit 31. The seal 32 includes a sealing ring 321 and a folding portion 322. The sealing ring 321 has an inner wall and an outer wall arranged oppositely, and the folding portion 322 is fixed on the outer wall 321b of the sealing ring. Wherein, the sealing ring 321 is arranged inside the conduit 31, and the outer wall 321b of the sealing ring faces the inner wall of the conduit 31, so that at least part of the folding portion 322 extends out from the inlet connection end 31a along the inner wall 321a of the sealing ring towards the outer wall 321b of the sealing ring, and is clamped and fixed between the sleeve 33 and the conduit 31.

[0049] It should be noted that the conduit 31 is used for fluid circulation. The conduit 31 can be set as various pipe bodies such as a round pipe or a square pipe, and the present utility model does not make any restrictions. The conduit 31 has a length direction extending along the X direction, and the two ends of the conduit 31 arranged at intervals along the length direction are respectively set as the inlet connection end 31a and the outlet connection end 31b. Among them, the inlet connection end 31a is used for fluid to enter the conduit 31 (for example, it can be used to connect the water outlet of a kettle). The outlet connection end 31b is used for fluid to discharge from the conduit 31 (for example, it can be used to connect the liquid extraction mechanism 20).

[0050] The seal 32 is used to seal the assembly gap between the external device of the conduit 31 and the inlet connection end 31a of the conduit 31. The sealing ring 321 of the seal 32 can be in an annular column shape and is arranged on the inner wall of the conduit 31. The sealing ring 321 has an inner wall and an outer wall arranged oppositely, and the inner wall 321a of the sealing ring points to the outer wall 321b of the sealing ring and is arranged along the Y direction in the figure. One side of the sealing ring 321 facing the inlet connection end 31a is provided with a flanging, the flanging is arranged along the circumferential direction of the sealing ring 321, and the flanging extends radially towards the outer wall 321b of the sealing ring to form a folding portion 322. When the seal 32 is installed on the inner wall of the conduit 31, the sealing ring 321 of the seal 32 is inserted into the conduit 31, and the folding portion 322 abuts against the edge of the inlet connection end 31a of the conduit 31.

[0051] The sleeve 33 is used to be fixed on the outer wall of the conduit 31 to cooperate with the conduit 31 to clamp the folding portion 322 of the seal 32 between the sleeve 33 and the conduit 31, so that the seal 32 is fixed inside the conduit 31 and prevent the seal 32 from falling off. Optionally, the seal 32 can be elastic, so as to undergo elastic deformation when the seal 32 is squeezed, and improve the sealing effect.

[0052] Therefore, when the sealing assembly 30 provided by the present utility model is installed, the sealing ring 321 of the seal 32 is inserted into the inner wall of the conduit 31, so that the folded portion 322 of the seal 32 abuts against the edge of the inlet connection end 31a. Then, the sleeve 33 is installed and fixed on the outer wall of the conduit 31, so as to squeeze the folded portion 322 of the seal 32 between the sleeve 33 and the conduit 31 through the cooperation of the sleeve 33 and the conduit 31, improve the fixing effect on the seal 32, and prevent the seal 32 from falling off.

[0053] Please refer to Figure 8 and Figure 9 , when the sealing assembly 30 is installed between the door hole 41a of the door 40 of the cabinet door and the liquid outlet hole 13 of the liquid storage device 10, the conduit 31 is installed in the door hole 41a of the cabinet door 40. The inlet connection end 31a of the conduit 31 is used to cooperate with the liquid outlet hole 13 of the liquid storage device 10, and the outlet connection end 31b of the conduit 31 is used to cooperate with the liquid taking mechanism 20 of the cabinet door 40. Among them, the liquid outlet hole 13 of the liquid storage device 10 is inserted into the sealing ring 321 of the seal 32, so that the sealing ring 321 is squeezed between the hole wall of the liquid outlet hole 13 of the liquid storage device 10 and the inner wall of the conduit 31, so as to seal the gap between the hole wall of the liquid outlet hole 13 and the inner wall of the conduit 31, and prevent the liquid flowing out of the liquid storage device 10 from leaking between the assembly parts of the liquid outlet hole 13 and the conduit 31, thereby reducing the residual liquid.

[0054] Compared with the related art method of fixing the seal by gluing, the sealing assembly 30 provided by the present utility model clamps and fixes the seal 32 through the cooperation of the conduit 31 and the sleeve 33, which can prevent the liquid from soaking the glue layer and causing the sealing ring 321 to fall off, thereby further improving the installation stability of the seal 32, improving the sealing effect, and further reducing the liquid leakage from the assembly part of the liquid storage device 10 and the conduit 31, and reducing the liquid residue.

[0055] In addition, through the sealing assembly 30 provided by the present utility model, an insertion fit is formed between the liquid outlet hole 13 of the liquid storage device 10 and the sealing assembly 30, which simplifies the assembly structure between the liquid storage device 10 and the cabinet door 40, facilitates the user to disassemble and assemble the liquid storage device 10 on the cabinet door 40 to clean the dirt at the liquid storage device 10 and the assembly part of the liquid storage device 10 and the cabinet door 40, and keeps the water outlet clean.

[0056] See back Figure 2 and Figure 3 , in some embodiments, in order to improve the fixing effect on the seal 32, the folded portion 322 is set to have an interference fit between the conduit 31 and the sleeve 33. Such a setting can limit and clamp the folded portion 322 in the X direction to prevent the seal 32 from shifting, thereby maintaining the sealing effect.

[0057] In some embodiments, to further improve the fixing effect on the seal 32, in the direction from the inner wall 321a of the sealing ring to the outer wall 321b of the sealing ring, the thickness of the folding portion 322 gradually increases.

[0058] With this setting, the different thicknesses of the folding portion 322 result in different extrusion forces on the folding portion 322 between the sleeve 33 and the catheter 31, which can limit and clamp the folding portion 322 in the Y direction. That is, in the direction from the inner wall 321a of the sealing ring to the outer wall 321b of the sealing ring, the thickness of the folding portion 322 gradually increases, which can prevent the folding portion 322 from moving in the Y direction. With this setting, when the liquid outlet hole 13 of the liquid storage device 10 is inserted into the inlet connection end 31a, it can avoid the occurrence of a gap between the sealing ring 321 and the hole wall of the liquid outlet hole 13, improve the sealing effect, and prevent liquid leakage.

[0059] Thus, the folding portion 322 is limited in both the X direction and the Y direction at the same time to improve the fixing effect on the seal 32, prevent the seal 32 from shifting, and further make the seal 32 firmly squeezed between the hole wall of the liquid outlet hole 13 and the inner wall of the catheter 31, improve the sealing effect of the seal 32, and reduce liquid leakage. Optionally, the folding portion 322 can be set as a wedge-shaped structure, and the present invention does not make any restrictions.

[0060] See Figure 2 , in some embodiments, to facilitate the user to easily insert and remove the liquid outlet hole 13 of the liquid storage device 10 from the inlet connection end 31a of the catheter 31, an installation gap 3212 is provided between the outer wall 321b of the sealing ring and the inner wall of the catheter 31. By providing the installation gap 3212, when the liquid outlet hole 13 of the liquid storage device 10 is inserted into the catheter 31, the compressed sealing ring 321 can move a small distance toward the inner wall of the catheter 31 to avoid the hole wall of the liquid outlet hole 13 being too tightly inserted with the sealing ring 321, resulting in difficulty in removing the liquid outlet hole 13 of the liquid storage device 10 from the catheter 31. However, it should be noted that although the sealing ring 321 can move a small distance toward the inner wall of the catheter 31, the sealing ring 321 is always sealed between the hole wall of the liquid outlet hole 13 and the inner wall of the catheter 31 to prevent liquid leakage.

[0061] Optionally, the range of the installation gap 3212 can be set to 0 to 1 millimeter. In this embodiment, a safety gap of 0.2 millimeter can be selected. Of course, in actual use, the installation gap 3212 can also be adaptively adjusted according to specific circumstances.

[0062] In some embodiments, to improve the sealing effect of the seal 32, at least one sealing rib 3211 is provided on the inner wall 321a of the sealing ring. Each sealing rib 3211 extends along the circumferential direction of the catheter 31, and two adjacent sealing ribs 3211 are spaced apart along the axial direction of the catheter 31.

[0063] It should be noted that during the insertion and extraction process of the liquid outlet hole 13 of the liquid storage device 10 and the inlet connection end 31a of the conduit 31, in order to cooperate with the slight movement of the sealing ring 321, the sealing rib 3211 always presses against the hole wall of the liquid outlet hole 13. By providing the sealing rib 3211 in this way, it is possible to prevent the liquid outlet hole 13 of the liquid storage device 10 from leaking when inserted into or pulled out of the conduit 31, so as to reduce the formation of residual liquid.

[0064] Optionally, in order to achieve double sealing and further improve the sealing effect, two sealing ribs 3211 can be provided. The two sealing ribs 3211 are arranged at intervals along the axial direction of the conduit 31 on the inner wall 321a of the sealing ring.

[0065] See Figures 2 to 4 , in some embodiments, to facilitate the tube sleeve 33 to cooperate with the conduit 31 to clamp the seal 32, the tube sleeve 33 includes a mounting portion 331 and a clamping portion 332. The mounting portion 331 is fixed to the outer wall of the conduit 31, and the clamping portion 332 is connected to the mounting portion 331 so that the clamping portion 332 cooperates with the conduit 31 to clamp the folded portion 322.

[0066] It should be noted that the mounting portion 331 is arranged as an annular column, and the mounting portion 331 is provided with a flange pointing from the outer wall 321b of the sealing ring towards the inner wall direction to form the clamping portion 332. When the mounting portion 331 is sleeved on the outer wall of the conduit 31 and fixed in the direction from the inlet connection end 31a to the outlet connection end 31b, the clamping portion 332 gradually approaches the inlet connection end 31a to squeeze the folded portion 322 of the seal 32, thereby fixing the seal 32.

[0067] In some embodiments, to facilitate the disassembly of the conduit 31 and the tube sleeve 33, the outer wall of the tube sleeve 33 is provided with an anti-slip portion 333. In this way, when the sleeve and the conduit 31 are arranged in a plug-in fit, the anti-slip portion 333 can be used to facilitate the user to apply an external force along the axial direction of the tube sleeve 33 to disassemble the tube sleeve 33 and the conduit 31.

[0068] Optionally, the outer wall of the tube sleeve 33 is provided with a flange that extends beyond the body, and the flange extends circumferentially along the tube sleeve 33 to form the anti-slip portion 333, so as to facilitate the user to hold the flange to disassemble and assemble the tube sleeve 33 and the conduit 31 along the axial direction of the tube sleeve 33. At the same time, the flange can be set in shapes such as square, circular, oval or polygonal, etc., and the present invention is not limited. In addition, the outer wall of the flange can also be provided with a plurality of anti-slip ribs to increase the friction force on the flange, so as to disassemble the tube sleeve 33 and the conduit 31. Optionally, the anti-slip ribs can be arranged at intervals along the axial direction of the tube sleeve 33, or set in shapes such as spiral, wavy or straight, etc., and the present invention is not limited.

[0069] In some embodiments, for the convenience of fixing the mounting portion 331 of the sleeve 33 to the catheter 31, the sealing assembly 30 includes a locking assembly 35. The locking assembly 35 is connected between the outer walls of the mounting portion 331 and the catheter 31 to fix the sleeve 33 to the catheter 31.

[0070] It should be noted that the locking assembly 35 is used to fix the mounting portion 331 to the outer wall of the catheter 31, so that the clamping portion 332 is fixed relative to the catheter 31, thereby maintaining the extrusion stability of the folded portion 322 of the seal 32. In addition, the locking assembly 35 includes a mating thread or a magnetic attraction assembly, etc., and the present utility model does not make any restrictions.

[0071] In some embodiments, for the convenience of installing the sleeve 33 and the catheter 31, the locking assembly 35 includes a first fastening portion 351 and a second fastening portion 352. The mounting portion 331 is provided with at least one first fastening portion 351, and the outer wall of the catheter 31 is provided with at least one second fastening portion 352. Each first fastening portion 351 cooperates with each second fastening portion 352 to fasten and fix the sleeve 33 and the catheter 31.

[0072] It should be noted that through the cooperation of the first fastening portion 351 and the second fastening portion 352, an insertion fit is formed between the catheter 31 and the sleeve 33, which facilitates the user to quickly assemble the catheter 31 and the sleeve 33 to fix the seal 32. Among them, for the convenience of processing the first fastening portion 351 and the second fastening portion 352, one of the first fastening portion 351 and the second fastening portion 352 is set as a slot, and the other is set as a tongue. The tongue is inserted into the slot to realize the fastening and assembly of the catheter 31 and the sleeve 33. Optionally, a plurality of first fastening portions 351 can be arranged along the circumferential direction of the sleeve 33, and a plurality of second fastening portions 352 can also be arranged along the circumferential direction of the catheter 31 to improve the fastening stability.

[0073] See Figure 4 and Figure 5 , in some embodiments, for the convenience of fastening the catheter 31 and the sleeve 33, the one of the sleeve 33 and the catheter 31 provided with the slot is further provided with a fastening guiding portion 38. The fastening guiding portion 38 and the slot are arranged at intervals along the axial direction of the sleeve 33, so that the tongue passes through the fastening guiding portion 38 and is inserted into the slot.

[0074] It should be noted that the buckling guiding portion 38 is used to guide the tongue to be inserted into the card slot, so that the catheter 31 is buckled with the sleeve 33. Optionally, the buckling guiding portion 38 can be set as a concave portion. As an example, the first buckling portion 351 of the sleeve 33 is set as a card slot, and the buckling guiding portion 38 and the card slot are arranged at intervals along the axial direction of the sleeve 33. When the sleeve 33 is buckled with the catheter 31, the tongue on the outer wall of the catheter 31 is first aligned with the buckling guiding portion 38, and then the sleeve 33 is pushed towards the catheter 31, so that the tongue passes through the buckling guiding portion 38 and is inserted into the card slot, and the assembly of the sleeve 33 and the catheter 31 can be completed, and the folded portion 322 of the seal 32 is squeezed and fixed between the two, saving time and effort in installation.

[0075] See Figures 5 to 7 , in some other embodiments, to facilitate the buckling of the catheter 31 and the sleeve 33, the sealing assembly 30 includes a guiding assembly. The guiding assembly includes a first guiding portion 36 and a second guiding portion 37. The sleeve 33 is provided with at least one first guiding portion 36, and the first guiding portion 36 and the first buckling portion 351 are arranged at intervals along the circumferential direction of the sleeve 33. The catheter 31 is provided with at least one second guiding portion 37, and each first guiding portion 36 cooperates with each second guiding portion 37 to enable the first buckling portion 351 and the second buckling portion 352 to be buckled.

[0076] It should be noted that the first guiding portion 36 and the second guiding portion 37 are used to guide the cooperation of the first buckling portion 351 and the second buckling portion 352. Optionally, one of the first guiding portion 36 and the second guiding portion 37 is set as a guiding groove, and the other is set as a guiding rib. The guiding groove extends along the axial direction of the catheter 31. By inserting the guiding rib into the guiding groove and sliding, the first buckling portion 351 and the second buckling portion 352 can be aligned and cooperated to realize the buckling assembly of the catheter 31 and the sleeve 33.

[0077] When the catheter 31 and the sleeve 33 are cooperatively installed, the seal 32 is loaded into the slot 343, then the first guiding portion 36 of the sleeve 33 is aligned with the second guiding portion 37 on the catheter 31, and then along the guidance of the first guiding portion 36 and the second guiding portion 37, the sleeve 33 is pushed towards the catheter 31, so that the first buckling portion 351 and the second buckling portion 352 are engaged, and the assembly of the sleeve 33 and the catheter 31 can be completed, and the folded portion 322 of the seal 32 is squeezed and fixed between the two, and the installation is simple and fast, saving time and effort.

[0078] See Figure 8 and Figure 9In some embodiments, in addition to operating the liquid taking mechanism 20 to take water from the liquid storage device 10 on the refrigerator 1, the user can also take the liquid storage device 10 out of the refrigerator 1 and directly use the pouring port of the liquid storage device 10 to pour ice water. At this time, in order to facilitate the user to directly take the liquid storage device 10 to take ice water, a switch valve can be set in the liquid outlet 13 of the liquid storage device 10. When the liquid storage device 10 is disassembled from the sealing assembly 30, the valve core 12 of the switch valve abuts against the liquid outlet 13 of the liquid storage device 10, closing the liquid outlet 13 and preventing the liquid storage device 10 from discharging water. When the liquid storage device 10 is plugged into the sealing assembly 30, the user presses the depressing tongue to separate the valve core 12 of the switch valve from the liquid outlet 13 of the liquid storage device 10 and open the liquid outlet 13. At this time, the user can take water from the liquid storage device 10 through the liquid taking mechanism 20.

[0079] For the liquid storage device 10 with a switch valve, the sealing assembly 30 includes a carrier 34. The carrier 34 includes a connecting portion 341 and a plug-in portion 342. The connecting portion 341 is connected to the inner wall of the conduit 31 to separate the cavity of the conduit 31 into a liquid inlet cavity 341a and a liquid outlet cavity 341b, and the connecting portion 341 is provided with at least one guide hole 344 connecting the liquid inlet cavity 341a and the liquid outlet cavity 341b. The plug-in portion 342 is connected to the connecting portion 341, and at least part of the plug-in portion 342 protrudes from the connecting portion 341 toward the inlet connection end 31a to form a slot 343 between the plug-in portion 342 and the inner wall of the liquid inlet cavity 341a. The sealing ring 321 is disposed in the slot 343.

[0080] It should be noted that the connecting portion 341 is used to support the plug-in portion 342, and cooperates with the plug-in portion 342 and the inner wall of the conduit 31 to form a slot 343. The connecting portion 341 can extend along the circumference of the conduit 31, and the connecting portion 341 is used to separate the cavity of the conduit 31 into a liquid inlet cavity 341a and a liquid outlet cavity 341b, and the liquid inlet cavity 341a and the liquid outlet cavity 341b are separated along the axial direction of the conduit 31. The liquid inlet cavity 341a is connected to the inlet connection end 31a, and the liquid outlet cavity 341b is connected to the outlet connection end 31b. In addition, a guide hole 344 is provided on the connecting portion 341, and the liquid inlet cavity 341a and the liquid outlet cavity 341b are connected through the guide hole 344.

[0081] The slot 343 is used to be inserted with the liquid outlet hole 13 of the liquid storage device 10. Since the sealing member 32 is installed in the slot 343, when the liquid outlet hole 13 of the liquid storage device 10 is inserted into the slot 343, the sealing member 32 is squeezed between the hole wall of the liquid outlet hole 13 and the inner wall of the conduit 31 to seal the assembly gap between the liquid outlet hole 13 and the inner wall of the conduit 31. After the switch valve in the liquid outlet hole 13 is opened, the liquid flowing out of the liquid storage device 10 is prevented from leaking from the assembly point between the liquid outlet hole 13 and the conduit 31, thereby reducing the residual liquid formed.

[0082] The insertion part 342 is used to cooperate with the liquid extraction mechanism 20 to control the opening and closing of the switching valve. When the user operates the liquid extraction mechanism 20 to draw water, the liquid extraction mechanism 20 can push the insertion part 342 to lift the valve core 12 of the switching valve, so that the valve core 12 is separated from the liquid outlet hole 13 to open the liquid outlet hole 13, and the user can draw water from the liquid extraction device. When the user does not operate the liquid extraction mechanism 20 to draw water, the insertion part 342 does not lift the valve core 12 of the switching valve, so that the valve core 12 abuts against the liquid outlet hole 13, closing the liquid outlet hole 13, and the user cannot draw water from the liquid extraction device. Among them, before the insertion part 342 lifts the valve core 12 of the switching valve and the switching valve is still in the closed state, the sealing rib 3211 of the sealing ring 321 has already contacted the hole wall of the liquid outlet hole 13, sealing the gap between the hole wall of the liquid outlet hole 13 and the sealing ring 321 to prevent water leakage.

[0083] In some embodiments, for the convenience of the user to draw water, the connecting part 341 can be set as a ring shape, and a notch at the center of the connecting part 341 forms a diversion hole 344 to communicate the liquid inlet cavity 341a and the liquid outlet cavity 341b. Among them, the insertion parts 342 are arranged at intervals along the circumferential direction of the diversion hole 344 to form a notch communicating with the diversion hole 344 between two adjacent insertion parts 342, facilitating the liquid in the liquid storage device 10 to flow out through the diversion hole 344.

[0084] Optionally, the diversion hole 344 is coaxially arranged with the conduit 31, so as to form uniformly spaced slots 343 between the insertion part 342 and the conduit 31. In this way, when the liquid outlet hole 13 is inserted into the slot 343, the seal 32 can be evenly squeezed between the outer wall of the liquid outlet hole 13 and the inner wall of the liquid inlet cavity 341a, so that the gap between the liquid outlet hole 13 and the liquid inlet cavity 341a is evenly sealed to improve the sealing performance and reduce liquid leakage. In addition, the coaxial arrangement of the diversion hole 344 and the conduit 31 can also facilitate the alignment of the insertion part 342 with the switching valve to cooperate with the liquid extraction mechanism 20 to control the opening and closing of the switching valve.

[0085] Of course, in other embodiments, the connecting part 341 can also be set as a circular baffle, with a plurality of diversion holes 344 distributed on the baffle, and a rib protruding toward the inlet connection end 31a is provided on the connecting part 341, and the rib forms the insertion part 342. Or, in other embodiments, the connecting part 341 and the insertion part 342 form a connecting rod assembly to cooperate with the liquid extraction mechanism 20 to control the opening and closing of the switching valve, which will not be elaborated in this utility model.

[0086] In some embodiments, to improve the sealing effect of the seal 32, the seal 32 includes an abutting part 323. The abutting part 323 is connected to the sealing ring 321 and is arranged in a dislocation manner with the folding part 322. The abutting part 323 is provided with a mating hole 323a, the abutting part 323 abuts against the connecting part 341, and the insertion part 342 passes through the mating hole 323a.

[0087] It should be noted that when the seal 32 is installed, the abutting portion 323 abuts against the connecting portion 341, which can support the folding portion 322 to abut against the edge of the inlet connecting end 31a, facilitating the clamping of the folding portion 322 by the pipe sleeve 33 and the conduit 31, thereby fixing the seal 32. In addition, the abutting portion 323 can be provided on the inner wall 321a of the sealing ring, and the abutting portion 323 extends along the direction from the outer wall to the inner wall, so that the abutting portion 323 is connected between the sealing ring 321 and the plugging portion 342 through the mating hole 323a, and it is also convenient to reserve an installation gap 3212 between the sealing ring 321 and the inner wall of the conduit 31.

[0088] See Figure 9 , the present utility model also provides a door 40 applying the above-mentioned sealing assembly 30, which facilitates the user to disassemble and assemble the liquid storage device 10 from the door 40 and reduces the residual liquid. The door 40 will be described below.

[0089] The door 40 provided by the present utility model includes a door body 41, a liquid storage device 10 and the above-mentioned sealing assembly 30. The door body 41 has an inner side of the door, an outer side of the door and a door hole 41a communicating the inner side of the door with the outer side of the door. The sealing assembly 30 is installed in the door hole 41a. The liquid storage device 10 is installed on the inner side of the door. The liquid storage device 10 has a liquid storage cavity 11 and a liquid outlet hole 13 communicating with the liquid storage cavity 11. The liquid outlet hole 13 of the liquid storage device 10 is inserted into the inlet connecting end 31a of the conduit 31, so that the seal 32 is squeezed to seal the gap between the hole wall of the liquid outlet hole 13 and the inner wall of the conduit 31.

[0090] It should be noted that the conduit 31 and the door 40 are set to be detachably connected, such as threaded connection or plug-in connection, etc., and the present utility model does not limit it. When the sealing assembly 30 is installed on the door 40, the liquid outlet hole 13 of the liquid storage device 10 can be inserted into the inlet connecting end 31a of the sealing assembly 30, and the seal 32 is squeezed between the hole wall of the liquid outlet hole 13 and the inner wall of the liquid inlet cavity 341a to seal the assembly gap between the liquid outlet hole 13 and the inner wall of the conduit 31. Thus, when the user takes water from the liquid storage device 10, the gap between the liquid outlet hole 13 of the liquid storage device 10 and the door hole 41a of the door 40 is sealed by the seal 32 to reduce the overflow of the liquid in the liquid storage device 10 from the assembly part of the liquid outlet hole 13 and the door hole 41a, thereby reducing the residual liquid.

[0091] In addition, through the sealing assembly 30 provided by the present utility model, a plug-in fit is formed between the liquid outlet hole 13 of the liquid storage device 10 and the sealing assembly 30, simplifying the assembly structure between the liquid storage device 10 and the door 40 of the refrigerator, and facilitating the user to disassemble and assemble the liquid storage device 10 on the door 40. On the one hand, the user can directly remove the liquid storage device 10 from the door 40 and pour the liquid through the water pouring port of the liquid storage device 10, facilitating the user to flexibly take ice water in various ways and further improving the user experience. At the same time, during the process of the user disassembling and assembling the liquid storage device 10, the liquid outlet hole 13 of the liquid storage device 10 is repeatedly inserted and pulled out from the inlet connection end 31a of the conduit 31. Since the sealing member 32 is firmly clamped between the sleeve 33 and the conduit 31, the sealing ribs 3211 on the sealing ring 321 always press against the outer wall of the liquid outlet hole 13 of the liquid storage device 10, preventing liquid from leaking out from the assembly part of the liquid outlet hole 13 and the conduit 31, thereby improving the sealing effect and reducing the residual liquid. Moreover, since the sealing member 32 is clamped by the sleeve 33 and the conduit 31, the connection stability of the sealing member 32 is better, and the sealing member 32 can be prevented from falling off, so that the sealing member 32 can maintain a good sealing effect between the liquid outlet hole 13 of the liquid storage device 10 and the door hole 41a.

[0092] Thus, for the door 40 provided by the present utility model, since the sealing member 32 is squeezed between the hole wall of the liquid outlet hole 13 and the inner wall of the conduit 31, the liquid in the liquid storage device 10 is prevented from leaking from the assembly part of the liquid outlet hole 13 and the conduit 31, thereby reducing the liquid residue and avoiding the residual liquid from contaminating the drinking water and the internal environment of the refrigerator 1. The user does not need to repeatedly clean the residual liquid, which saves time and effort and improves the user experience.

[0093] For the liquid storage device 10 with a switch valve, a carrier 34 is provided on the inner wall of the sealing assembly 30. After the sealing assembly 30 is installed in the door hole 41a of the door 40, it needs to cooperate with the liquid taking mechanism 20 to move to lift the valve core 12 of the switch valve, so that the switch valve is opened and the liquid in the liquid storage device 10 flows out to realize water taking. Hereinafter, the present utility model further describes the application of the sealing assembly 30 with the carrier 34 to the door 40.

[0094] The door 40 of the box includes a door body 41, a liquid storage device 10, a liquid extraction mechanism 20, and the above-mentioned sealing assembly 30. The liquid extraction mechanism 20 includes a distribution component 22 and a liquid outlet component 21. The door body 41 has an inner side of the door, an outer side of the door, and a door hole 41a communicating the inner side of the door with the outer side of the door. The distribution component 22 is arranged on the outer side of the door. The sealing assembly 30 is installed in the door hole 41a. The liquid storage device 10 is installed on the inner side of the door. The liquid outlet hole 13 of the liquid storage device 10 is inserted into the inlet connection end 31a of the conduit 31, so that the seal 32 is squeezed to seal the gap between the hole wall of the liquid outlet hole 13 and the inner wall of the conduit 31. And the insertion part 342 of the sealing assembly 30 is connected to the valve core 12 of the switch valve. The liquid outlet component 21 is connected to the outlet connection end 31b of the sealing assembly 30 and extends from the door hole 41a to the outer side of the door to be connected to the distribution component 22.

[0095] Among them, the distribution component 22 includes a distribution housing 22a and a force-receiving part 22b. The distribution housing 22a is fixed to the door body 41, and the force-receiving part 22b is rotatably connected to the distribution housing 22a. As an example, the force-receiving part 22b is set as a pressing tongue. The top end of the pressing tongue is rotatably connected to the distribution housing 22a, and the bottom end of the pressing tongue is set as a free end. A torsion spring is arranged between the distribution housing 22a and the pressing tongue. When the user presses the free end of the pressing tongue, the torsion spring deforms, and the pressing tongue can rotate around the top end of the pressing tongue. When the user cancels the pressing on the pressing tongue, the torsion spring restores its deformation to reset the pressing tongue from the pressing position to the idle position.

[0096] The liquid outlet component 21 includes a liquid outlet housing 211, an elastic connecting piece 213, and a liquid outlet core 212. The liquid outlet housing 211 has a liquid outlet cavity 341b, an inlet end and an outlet end communicating with the liquid outlet cavity 341b. Among them, the inlet end of the liquid outlet housing 211 is connected to the outlet connection end 31b of the sealing assembly 30. The outlet end of the liquid outlet channel 20a extends from the door hole 41a to the outer side of the door. The liquid outlet core 212 is slidably arranged in the liquid outlet cavity 341b of the liquid outlet housing 211, and a liquid outlet channel 20a is formed between the outer wall of the liquid outlet core 212 and the inner wall of the liquid outlet housing 211. The elastic connecting piece 213 is connected between the liquid outlet core 212 and the liquid outlet housing 211. In addition, the liquid outlet core 212 is connected to the force-receiving part 22b of the distribution component 22, so that the liquid outlet core 212 can press against or separate from the outlet end of the liquid outlet housing 211, thereby opening or closing the liquid outlet channel 20a.

[0097] When the user draws water, the user presses the tongue of the dispensing member 22. The tongue of the dispensing member 22 rotates relative to the door body 41 to push the liquid outlet core 212 of the liquid outlet member 21 to move upward along the axis of the door hole 41a, opening the outflow end of the liquid outlet channel 20a. At the same time, the elastic connecting member 213 between the liquid outlet core 212 and the liquid outlet housing 211 drives the liquid outlet housing 211 to move upward along the axis of the door hole 41a. The liquid outlet housing 211 then pushes the sealing assembly 30 to move upward along the axis of the door hole 41a to use the plugging portion 342 to lift the valve core 12 of the switching valve, so that the valve core 12 of the switching valve is separated from the liquid outlet hole 13, opening the liquid outlet hole 13, and enabling the liquid in the liquid storage device 10 to flow to the liquid outlet member 21 through the sealing assembly 30, thereby realizing water intake by the user.

[0098] When the user stops drawing water, the user withdraws the pressing force on the tongue of the dispensing member 22. The tongue of the dispensing member 22 rotates and resets, driving the liquid outlet core 212 to move downward along the axis of the door hole 41a to press against the outflow end of the liquid outlet channel 20a, closing the liquid outlet channel 20a. At the same time, the elastic connecting member 213 resets to drive the liquid outlet housing 211 to move downward along the axis of the door hole 41a. The liquid outlet housing 211 drives the sealing assembly 30 to move downward along the axis of the door hole 41a, causing the plugging portion 342 to separate from the valve core 12 of the switching valve. The valve core 12 of the switching valve is reset by the elastic member to press against the liquid outlet hole 13, closing the liquid outlet hole 13, and the liquid in the liquid storage device 10 no longer flows out, and the user stops drawing water.

[0099] Wherein, the conduit 31 and the liquid outlet housing 211 are arranged to be detachably connected, such as by screw connection, plug connection, etc., and the present utility model does not make any restrictions. As an example, the outer wall of the conduit 31 is provided with a first mating portion and a second mating portion, and the first mating portion and the second mating portion are arranged at intervals along the length direction of the conduit 31. The first mating portion is arranged as a plug block for slidably connecting the conduit 31 with the door of the box 40. The second mating portion is arranged as an external thread for threadedly connecting the conduit 31 with the liquid taking mechanism 20.

[0100] See Figure 10 The present utility model also provides a refrigerator 1 applying the above-mentioned door of the box 40 to facilitate improving the user experience of using the refrigerator 1. The refrigerator 1 will be described below.

[0101] The refrigerator 1 provided by the present utility model includes a box body 50 and the above-mentioned door 40. The box body 50 includes a refrigerating chamber 51, and the door body 41 is connected to the box body 50 to open and close the refrigerating chamber 51. Among them, the inner side of the door faces the refrigerating chamber 51, and the outer side of the door faces away from the refrigerating chamber 51. With such a setting, the liquid storage device 10 is arranged on the side of the door body 41 facing the refrigerating chamber 51 to cool the liquid in the liquid storage device 10 by using the refrigeration function of the refrigerator 1. The liquid outlet component 21 extends from the side of the door body 41 facing away from the refrigerating chamber 51, so that the user can press the pressing tongue from outside the door 40 to take the ice water in the liquid storage device 10, thereby reducing the opening and closing of the door 40 and reducing the cold leakage of the refrigerator 1.

[0102] In addition, since the door 40 is provided with a sealing component 30, the assembly sealing performance between the liquid outlet hole 13 of the liquid storage device 10 and the door 40 is improved through this sealing component 30, avoiding the outflow of liquid from the assembly part between the liquid outlet hole 13 and the door 40 and reducing the liquid residue. At the same time, through this sealing component 30, the liquid storage device 10 and the door 40 can be plugged and matched, simplifying the assembly structure between the liquid storage device 10 and the door 40, facilitating the user to disassemble and assemble the liquid storage device 10 on the door 40 to take out the liquid storage device 10 from the refrigerator 1, and directly pouring the liquid in the liquid storage cavity 11 through the water pouring port of the liquid storage device 10 to realize flexible water taking in multiple ways.

[0103] In some embodiments, the box body 50 may also have at least one of a freezing chamber 52, a variable temperature chamber and a fresh-keeping chamber, which is not limited in the present utility model. In addition, other structures of the refrigerator 1 are not elaborated in the present utility model.
