Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a water system and a dishwasher. Background Technology

[0002] With the continuous progress of society, people are becoming increasingly intelligent with kitchen appliances. Dishwashers are favored by many because of their good cleaning effect, multiple disinfection functions, and time and labor saving. They can reduce people's labor burden in modern life.

[0003] To meet users' requirements for loading different sized dishes into the dishwasher and to rationally allocate the dishwasher's internal space according to the size of the dishes, the dish rack can be designed with height adjustment or unilateral tilting functions. In related technologies, to match the height adjustment or unilateral tilting functions of the dish rack, the water distributor is connected to the internal water pipe through a pipe-to-pipe connection method. The connection position is relatively fixed, and when the dish rack needs to be adjusted in multiple stages or tilted, the sealing of the water distributor cannot be guaranteed. Utility Model Content

[0004] This application provides a water system and a dishwasher that can improve the sealing performance of the water system.

[0005] In a first aspect, embodiments of this application provide a water system applied to a dishwasher. The dishwasher includes an inner tub, a dish rack, and a door. The dish rack is removably disposed within the inner tub. The door is used to open or close the opening of the inner tub. The water system includes a water inlet pipe, a water distributor, a spray arm assembly, and a flexible seal. The water inlet pipe is used to connect to an external water supply. The water distributor is disposed on the water inlet pipe and has a water outlet. The spray arm assembly is configured to connect to the dish rack and includes a water inlet end. The flexible seal includes a connecting end and a sealing end. A water passage is provided within the flexible seal, connecting the connecting end and the sealing end. The connecting end is sealed to the water inlet end, and the sealing end has a trumpet-shaped structure. During the process of the door closing the opening of the inner tub, the dish rack is pushed against the door, causing the sealing end of the flexible seal to seal against the water distributor and cover the outside of the water outlet, so that the water passage communicates with the water outlet.

[0006] In some embodiments, the water distributor is configured to have a water outlet surface inside the inner tank, the water outlet surface being provided with the water outlet, and during the process of the door closing the opening of the inner tank, the sealing end of the flexible seal seals abuts against the water outlet surface.

[0007] The water outlet is located in the middle of the water outlet surface.

[0008] In some embodiments, when the sealing end is sealed against the water outlet surface, the inner wall of the sealing end and the water outlet have an adjustable gap in both the vertical and horizontal directions.

[0009] In some embodiments, the adjustment spacing includes a first adjustment spacing in the vertical direction and a second adjustment spacing in the horizontal direction, wherein the first adjustment spacing is greater than the second adjustment spacing.

[0010] In some embodiments, the water passage has at least two water inlets at the sealing end, the diameter of the water inlets is larger than the diameter of the water outlet, and the two water inlets are arranged vertically and are interconnected.

[0011] In some embodiments, the plane containing the water inlet is arranged parallel to the water outlet surface.

[0012] In some embodiments, the connection end is interference-fitted with the water inlet end.

[0013] In some embodiments, the inlet end is formed with an annular sealing groove with the opening facing the outlet surface, the wall thickness of the connecting end is greater than the width of the annular sealing groove, and the connecting end is embedded in the annular sealing groove.

[0014] In some embodiments, an annular sealing rib is further protruding on the inner and / or outer wall of the connecting end, and the annular sealing rib seals against the groove wall of the annular sealing groove.

[0015] In some embodiments, the flexible seal includes a deformable portion connected between the connecting end and the sealing end, the deformable portion having a bellows structure.

[0016] Secondly, embodiments of this application provide a dishwasher that includes a water system as described in any of the foregoing claims.

[0017] Based on the water system of this application embodiment, by setting a flexible seal, when the door closes the opening of the inner tank, the dish rack is pushed against the door, causing the sealing end of the flexible seal to seal against the water distributor and cover the outside of the water outlet, so that the water passage is connected to the water outlet. The sealing end has a funnel-shaped structure, which can give the side of the sealing end that abuts against the water distributor a certain tension force, so that the sealing end and the water distributor abut against each other more tightly. During the operation of the dishwasher, it ensures the tight connection between the spray arm assembly and the water inlet pipe. Since the inside of the inner tank is a relatively sealed environment after the door closes the opening of the inner tank, the sealing end of the flexible seal seals against the water distributor and covers the outside of the water outlet, which ensures that the high-pressure and high-temperature water flowing out of the water inlet pipe is not leaked, and also prevents water vapor from overflowing, thereby improving the airtightness of the water system.

[0018] Furthermore, while ensuring a tight seal, when the door is closed, the flexible seal is activated by the door, and the sealing end of the flexible seal comes into contact with the water distributor, thus connecting the water passage to the water outlet. This simultaneously connects the spray arm assembly to the water inlet pipe, greatly improving the efficiency of pipe connection. No manual connection is required, improving the accuracy and convenience of pipe connection. In this way, during the washing process, water can flow smoothly from the water passage to the spray arm assembly, and then supply water to the spray arm assembly to complete the washing and spraying process.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] With the continuous progress of society, people are becoming increasingly intelligent with kitchen appliances. Dishwashers are favored by many because of their good cleaning effect, multiple disinfection functions, and time and labor saving. They can reduce people's labor burden in modern life.

[0036] To meet users' needs for accommodating different sized tableware and allocating internal space according to the size of the tableware, dishwashers with two- or three-tier designs feature an adjustable upper rack. For these models, when large items like pots or plates need to be placed in the lower rack, the upper rack can be adjusted to a higher position, increasing the maximum size of tableware that can be placed in the lower rack. Conversely, adjusting the upper rack to a lower position provides more space for tea trays or cup holders between the tray and the upper rack.

[0037] like Figure 1 and Figure 2 As shown, this application proposes a dishwasher 1000, which includes an inner tub 200, a dish rack 300, and a door 400. The dish rack 300 is removably disposed in the inner tub 200, and the door 400 is used to open or close the opening 201 of the inner tub 200.

[0038] The dish rack 300 can be an upper dish rack located on the upper part of the inner liner 200, or it can be a lower dish rack located at the bottom of the inner liner 200. That is, there can be one or more dish racks 300 in this application. The dish rack 300 can be pulled out relative to the inner liner 200 by providing a sliding rail structure on both the inner liner 200 and the dish rack 300. The sliding rail structure ensures that the dish rack 300 can smoothly and steadily enter and exit the dishwasher 1000, facilitating the user's placement and removal of tableware. Of course, the pull-out form of the dish rack 300 can also be other forms, and this application does not limit this.

[0039] Furthermore, to accommodate bowls and plates of different heights, multiple racks can be provided on the inner wall of the inner liner 200. These racks are spaced apart in the vertical direction of the inner liner 200, allowing the bowl basket 300 to be placed on racks of different heights on opposite sides. This creates a height difference between the opposite sides of the bowl basket 300, enabling the bowl basket 300 to be tilted on one side. This allows for flexible placement of tableware on the bowl basket 300, meeting different user needs.

[0040] In related technologies, in order to accommodate the adjustable height or unilateral tilt function of the dish basket, the water distributor 20 is connected to the inner water pipe by connecting pipes from one end to another. The connection position is relatively fixed. When the dish basket 300 needs multi-level adjustment or tilt adjustment, the sealing of the water distributor 20 cannot be guaranteed.

[0041] To resolve the above issues, please refer to [link / reference]. Figures 2 to 4 This application proposes a water system 100 for use in a dishwasher 1000. In the embodiments of this application, the water system 100 includes an inlet pipe 10, a water distributor 20, a spray arm assembly 30, and a flexible seal 40.

[0042] The water inlet pipe 10 is used to connect to the external water supply. The water distributor 20 is installed on the water inlet pipe 10 and can control the water supply of the dishwasher 1000 to ensure that the dishwasher 1000 has an appropriate amount of water to work during the washing process, prevent the residual water in the spray arm water pipe 32 from flowing back, ensure that the inside of the dishwasher 1000 is dry, and avoid bacterial growth. The water distributor 20 is configured to have a water outlet surface 21 in the inner tank 200, and a water outlet 22 is provided on the water outlet surface 21.

[0043] The spray arm assembly 30 is configured to connect to the dish rack 300. The spray arm assembly 30 includes a spray arm body 31 and a spray arm water pipe 32. The spray arm water pipe 32 includes a water outlet 321 and a water inlet 322. The water outlet 321 is connected to the spray arm body 31. The spray arm assembly 30 and the dish rack 300 can be located at the top of the inner tank 200 or at the bottom of the inner tank 200. In this application, dish racks 300 can be evenly spaced in the vertical direction of the dishwasher 1000. The dish rack 300 located at the top is called the upper dish rack, and the dish rack 300 located at the bottom is called the lower dish rack. The spray arm assembly 30 is located below the upper dish rack and between the upper and lower dish racks, which can achieve simultaneous rinsing from both the top and bottom. This provides a better rinsing effect on the dishes in both the upper and lower dish racks and increases the spray coverage of the cleaning water.

[0044] The spray arm assembly 30 also includes a spray arm base (not shown in the figure). The spray arm body 31 is connected to the spray arm base. The spray arm base is equipped with a rotating shaft structure that can drive the spray arm body 31 to rotate. The spray arm body 31 is also provided with multiple spray holes, the size, angle, and number of which are not limited. During the operation of the dishwasher 1000, the spray arm body 31 rotates, spraying pressurized water from the spray holes at different angles. The dense water streams cross and rinse each other to form a near-ring shape, achieving cleaning of the tableware in the dish rack 300. This design helps improve the cleaning efficiency of the dishwasher 1000, ensuring that all parts of the tableware are effectively cleaned.

[0045] Please refer to Figures 3 to 6The flexible seal 40 includes a connecting end 41 and a sealing end 42. A water passage 43 is provided within the flexible seal 40, connecting the connecting end 41 and the sealing end 42. During operation of the dishwasher 1000, the sealing end 42 of the flexible seal 40 seals against the water outlet surface 21. The connecting end 41 is sealed and fitted with the water inlet end 322, ensuring that the flexible seal 40 will not loosen and leak, thus improving the sealing performance of the connection between the connecting end 41 and the water inlet end 322.

[0046] During the process of the door 400 closing the opening 201 of the inner liner 200, the dish rack 300 is pushed against the door 400, causing the sealing end 42 of the flexible seal 40 to seal against the water outlet surface 21 and cover the outside of the water outlet 22, so that the water passage 43 is connected to the water outlet 22. This technical solution, by setting the flexible seal 40, ensures the tight connection between the spray arm water pipe 32 and the water inlet pipe 10 during the operation of the dishwasher 1000. Since the door 400 closes the opening 201 of the inner liner 200, the interior of the inner liner 200 is a relatively sealed environment. The sealing end 42 of the flexible seal 40 seals against the water outlet surface 21 and covers the outside of the water outlet 22, ensuring that the high-pressure, high-temperature water flowing from the water inlet pipe 10 is not leaked, and also preventing water vapor from overflowing, thereby improving the airtightness of the water system 100.

[0047] Furthermore, while ensuring the connection is airtight, when the door is closed, the dish rack 300 is pushed against the door body 400, which drives the flexible seal 40. The sealing end 42 of the flexible seal 40 seals against the water outlet surface 21, so that the water passage 43 is connected to the water outlet 22. This simultaneously realizes the connection between the spray arm water pipe 32 and the water inlet pipe 10, which greatly improves the efficiency of pipe connection. No manual connection operation is required, which improves the accuracy and convenience of pipe connection. In this way, during the washing process, water can flow smoothly from the water passage 43 to the spray arm water pipe 32, and then supply water to the spray arm body 31 to complete the washing and spraying process.

[0048] The flexible seal 40 can be made of materials such as silicone or rubber, and has good flexibility and compression rebound characteristics. It can maintain its performance without damage in the high temperature environment of the dishwasher 1000. The flexible seal 40 can deform when the dish rack 300 is pushed by the door 400, thereby sealing the water outlet 22. It also ensures a certain distance between the spray arm water pipe 32 and the water inlet pipe 10, ensuring the tightness of the connection between the water passage 43 and the water outlet 22, preventing water leakage from affecting other working components inside the inner tank 200, and improving the sealing and safety of the water system 100. It should be noted that the flexible seal 40 can also be installed on the water outlet surface 21 of the water distributor 20. After the door 400 closes the opening 201 of the inner tank 200, the flexible seal 40 is also pressed between the water outlet surface 21 and the water inlet end 322, so as to realize the connection between the water passage 43 of the flexible seal 40 and the water inlet end 322 and the water outlet 22 of the spray arm water pipe 32. This application does not limit this.

[0049] In some embodiments, the sealing end 42 has a trumpet-shaped structure, and the cross-sectional area of ​​the inner cavity of the sealing end 42 gradually increases in the direction towards the water outlet surface 21. This increases the contact area between the sealing end 42 and the water outlet surface 21, thereby improving the sealing effect of the flexible seal 40. When the sealing end 42 abuts against the water outlet surface 21, the flexible seal 40 is pressed between the spray arm water pipe 32 and the water distributor 20, and therefore is subjected to a certain amount of compressive force. Furthermore, the sealing end 42 has a certain degree of flexibility, and the trumpet-shaped structure of the sealing end 42 allows the side of the sealing end 42 that abuts against the water outlet surface 21 to have a certain amount of tension, making the contact between the sealing end 42 and the water outlet surface 21 more tight, thereby further improving the sealing performance of the water system 100. The funnel-shaped structure of the sealing end 42 also helps to optimize water flow dynamics. As the water flows from the outlet 22 of the water distributor 20 to the water passage 43, the cross-sectional area of ​​the inner cavity of the sealing end 42 gradually increases in the direction towards the water outlet surface 21, causing the water passage 43 at the sealing end 42 to narrow from wide to narrow. This allows the water flow to be more concentrated when it passes through, thereby increasing the water pressure and the speed of the water flow. This can increase the impact force of the water flow and enhance the washing effect.

[0050] In some embodiments, since the bowl basket 300 is configured to be movable and adjustable in the vertical direction, and one side of the bowl basket 300 can also be relatively tilted, and the spray arm assembly 30 is connected to the bottom of the bowl basket 300, in order to ensure that the water distributor 20 and the spray arm water pipe 32 can still be quickly and accurately aligned and connected when the door 400 closes the opening 201, so that the water passage 43 and the water outlet 22 can communicate and supply water, in the state where the sealing end 42 is sealed and abuts against the water outlet surface 21, there is an adjustable gap between the inner wall of the sealing end 42 and the water outlet 22 in both the vertical and horizontal directions.

[0051] By adjusting the distance between the sealing end 42 and the water outlet 22, different installation environments and angles can be accommodated. When the basket 300 is pressed against the door 400, the horizontal adjustment distance between the inner wall of the sealing end 42 and the water outlet 22 prevents the spray arm assembly 30 from directly contacting and pressing against the water distributor 20 due to excessive stroke, thus avoiding interference between the components. This ensures that the sealing end 42 can tightly fit against the water outlet surface 21 of the water distributor 20. In addition, the water outlet 22 is located in the middle of the water outlet surface 21, which provides sufficient contact area for the vertical and horizontal adjustment distance between the inner wall of the sealing end 42 and the water outlet 22. This prevents the sealing end 42 from failing to fully contact the water outlet surface 21, avoiding gaps between the sealing end 42 and the water outlet surface 21 during contact, which could lead to sealing failure.

[0052] In one embodiment of this application, a limiting part 24 can be provided in the water distributor 20. The limiting part 24 extends from the opposite sides of the water outlet surface 21 toward the basket 300. A stop part 323 can be provided on the water inlet end 322 of the spray arm water pipe 32 or on the basket 300. Multiple stop parts 323 can be provided, and multiple stop parts 323 are provided on opposite sides in the width direction of the water inlet end 322 and are spaced apart in the vertical direction. When the door 400 pushes the basket 300, the limiting part 24 is limited between two adjacent stop parts 323 in the vertical direction, thereby preventing the basket 300 from shaking in the vertical direction, thereby reducing the misalignment caused by shaking, avoiding sealing failure, and thus ensuring the sealing effect.

[0053] Appropriate adjustment spacing can reduce the impact of water flow on the sealing end 42, reduce the risk of leakage due to uneven pressure or improper installation, thereby improving the overall sealing performance of the water system 100. Adjustment spacing in both the horizontal and vertical directions also provides more flexibility to the flexible seal 40, reducing seal failure due to vibration or temperature changes, making the sealing connection of the flexible seal 40 more stable during dishwasher 1000 operation. The vertical adjustment spacing between the inner wall of the sealing end 42 and the outlet 22 allows for better adaptation to the vertical adjustment and unilateral tilting of the dish rack 300. When the dish rack 300 is adjusted, the sealing end 42 of the flexible seal 40 can still accurately align with the outlet 22, ensuring complete coverage of the outlet 22 when the sealing end 42 seals against the water outlet surface 21, preventing leakage and thus improving the sealing performance of the water system 100.

[0054] Specifically, the adjustment spacing includes a first adjustment spacing L1 in the vertical direction and a second adjustment spacing L2 in the horizontal direction. Due to the internal structure of the inner liner 200 and the placement requirements of the tableware on the bowl basket 300, if the angle of tilt of the bowl basket 300 on one side is large, the stability of the tableware on the bowl basket 300 will be relatively poor. The range of motion of the bowl basket 300 in the vertical direction is greater than the range of motion when the bowl basket 300 is tilted on one side. Therefore, the first adjustment spacing L1 is greater than the second adjustment spacing L2.

[0055] In some embodiments, the water passage 43 has at least two water inlets 431 formed at the sealing end 42. The diameter of the water inlet 431 is larger than the diameter of the outlet 22, and the two water inlets 431 are arranged vertically and interconnected. In this way, sufficient adjustment distance can be reserved in the vertical direction so that when the basket 300 moves up and down and is erected at different heights, at least one water inlet 431 can be aligned and connected with the outlet 22, avoiding leakage caused by the sealing end 42 not being able to completely cover the outside of the outlet 22, thereby improving the sealing effect.

[0056] Specifically, the plane of the water inlet 431 is parallel to the water outlet surface 21. This arrangement ensures that when the sealing end 42 seals against the water outlet surface 21, the distance between the water inlet 431 and the water outlet 22 is consistent, resulting in a tighter and more consistent fit between the sealing end 42 and the water outlet surface 21. This ensures that the water can flow smoothly from the water outlet 22 into the water inlet 431. Furthermore, the mutual contact between the parallel planes helps reduce eddies and turbulence in the water flow as it flows from the water outlet 22 into the water inlet 431, preventing water flow turbulence from reducing water flow efficiency or even causing structural damage.

[0057] In some embodiments, please refer to Figures 6 to 8 The connecting end 41 and the inlet end 322 are interference-fitted, achieving a tight fit through elastic deformation. The inlet end 322 has an annular sealing groove 3221 with its opening facing the outlet surface 21. The wall thickness of the connecting end 41 is greater than the width of the annular sealing groove 3221. The connecting end 41 is embedded in the annular sealing groove 3221, achieving a tight connection between the connecting end 41 and the inlet end 322. This ensures that when the flexible seal 40 is subjected to resistance, the connecting end 41 will not loosen from the inlet end 322, thus preventing seal failure and leakage. The interference fit between the connecting end 41 and the inlet end 322 effectively transmits torque and resists external forces, thereby reducing the risk of leakage at the connection. The interference fit also improves the integrity of the entire connection structure because the mutual compression between the connecting end 41 and the inlet end 322 tightly binds them together, forming a tightly connected structural unit. This connection method has greater rigidity and higher stability, helping to ensure the sealing performance of the flexible seal 40 under high pressure or dynamic conditions.

[0058] Furthermore, the interference fit allows for a certain degree of dimensional tolerance. Even if there are slight variations in the wall thickness of the connecting end 41 and the groove width of the annular sealing groove 3221, a tight fit can still be achieved. This adaptability helps to ensure consistent sealing performance under different production batches and usage conditions.

[0059] In addition to the interference fit of the connecting end 41 embedded in the annular sealing groove 3221, the connection between the connecting end 41 and the water inlet end 322 can also be a screw connection, a snap connection, or a clamp connection. For example, the connecting end 41 and the water inlet end 322 can be connected by a rubber expansion joint. The rubber joint can absorb the stress caused by vibration and temperature changes, allowing the pipeline to have a certain displacement. Alternatively, the connecting end 41 and the water inlet end 322 can be connected by a metal clamp and a rubber washer. This arrangement allows for a certain displacement and angle change between the connecting end 41 and the water inlet end 322, which is convenient for installation and maintenance, and can also adapt to the up-and-down movement and tilting of the basket 300. This application does not limit the connection between the connecting end 41 and the water inlet end 322, that is, the connection between the flexible seal 40 and the spray arm water pipe 32.

[0060] An annular sealing rib 411 is also formed protruding on the inner wall and / or outer wall of the connecting end 41. That is, the annular sealing rib can be formed protruding on the inner wall of the connecting end 41 or on the outer wall of the connecting end 41. Of course, annular sealing ribs 411 can also be provided on both the inner wall and the outer wall of the connecting end 41. The annular sealing rib 411 seals against the wall of the annular sealing groove 3221, which can improve the tightness and stability of the connection between the connecting end 41 and the water inlet end 322. The annular sealing rib 411 can increase the friction between the connecting end 41 and the wall of the annular sealing groove 3221. During the process of the door 400 closing the opening 201 of the inner tank 200, the basket 300 is pushed against by the door 400, and the sealing end 42 of the flexible seal 40 is driven to seal against the water outlet surface 21. The annular sealing rib 411 seals against the wall of the annular sealing groove 3221, which can prevent the connecting end 41 from coming loose from the water inlet end 322 when the flexible seal 40 is squeezed and vibrated during the contact process, thus ensuring the sealing performance of the flexible seal 40 and further improving the sealing performance of the water system 100.

[0061] In some embodiments, the flexible seal 40 includes a deformable portion 44 connected between the connecting end 41 and the sealing end 42. The deformable portion 44 has a bellows structure. The multi-layered corrugated design of the bellows structure enables the flexible seal 40 to have a certain degree of elasticity and deformation capacity under stress, which can better adapt to temperature changes or mechanical vibrations generated during the operation of the dishwasher 1000. When the sealing end 42 of the flexible seal 40 seals against the water outlet surface 21 and covers the outside of the water outlet 22, the flexible seal 40 needs to withstand a certain pressure to ensure a tight connection between the sealing end 42 and the water outlet surface 21. At this time, the bellows structure design of the deformable portion 44 can withstand greater stress, achieving a tighter sealing effect and preventing leakage. Furthermore, the bellows structure can actively adjust its shape according to changes in fluid pressure within the water passage 43 to maintain a stable sealing effect. This elastic deformation capability allows the bellows to adapt to changes in fluid pressure, achieving a reliable sealing effect.

[0062] Since the deformation part 44 is a bellows structure, it can expand and contract, and it can achieve displacement compensation in the axial direction. That is, when the bowl basket 300 is not pushed in completely, resulting in an excessively large adjustment distance, or when the bowl basket 300 is subjected to a large thrust, resulting in a small adjustment distance, or when the bowl basket 300 is adjusted in the vertical direction or placed tilted on one side, the deformation part 44 can expand and contract in the vertical and horizontal directions to adapt to the above situations, so as to ensure the tightness of the connection between the sealing end 42 and the water outlet surface 21, thereby further improving the sealing performance.

[0063] In some embodiments, please refer again Figures 6 to 8 The water system 100 also includes a mounting component 50, which includes a mounting portion 51 and a first flange 52 connected together. The mounting portion 51 is connected to the inner wall of the inner tank 200, and the first flange 52 is connected to opposite sides of the mounting portion 51. The first connecting portion extends toward the water inlet pipe 10 and is located on opposite sides of the water inlet pipe 10, thereby fixing the water inlet pipe 10 to the inner wall of the inner tank 200. The outlet surface 21 of the water distributor 20 extends toward the water inlet pipe 10 on opposite sides and forms a second flange 23. Both the second flange 23 and the first flange 52 are connected to the side wall of the water inlet pipe 10, thereby fixing the water distributor 20 to the water inlet pipe 10.

[0064] Specifically, a first slot 521 can be provided on the first flange 52, and a second slot 231 can be provided on the second flange 23. First buckles 13 are provided on opposite sides of the water inlet pipe 10. The first buckles 13 are inserted into the second slots 231 to connect the water distributor 20 and the water inlet pipe 10. A second buckle 232 is also provided on the second flange 23. The second buckle 232 is inserted into the first slots 521 to connect the water distributor 20, the water inlet pipe 10, and the mounting component 50 to form a stable overall structure. At this time, the water distributor 20 and the water inlet pipe 10 are fixed to the inner wall of the inner tank 200 by the mounting component 50, which improves the integrity and stability of the structure and ensures a more stable connection between the water outlet 22 of the water distributor 20 and the water passage 43, thereby improving the airtightness.

[0065] The connection method between the mounting part 51 and the inner wall of the inner liner 200 includes, but is not limited to, screwing, welding or snap-fitting. In this embodiment, the mounting part 51 is provided with a snap-fit ​​hole 511 and the inner wall of the inner liner 200 is provided with a snap-fit ​​protrusion. The snap-fit ​​protrusion is snapped into the snap-fit ​​hole 511 to fix the mounting part 50 to the inner wall of the inner liner 200, thereby fixing the water inlet pipe 10 to the inner wall of the inner liner 200. This application does not limit this.

[0066] Furthermore, the inlet pipe 10 is also equipped with a water inlet 11, which is aligned with the outlet 22 of the water distributor 20. A flange 12 protrudes from the periphery of the water inlet 11, extending into the outlet 22 without exceeding the outlet surface 21. The flange 12 extending into the outlet 22 can enhance the structural strength of this part and prevent damage caused by water pressure or other external forces. In the actual assembly process, the water inlet 11 of the inlet pipe 10 and the outlet 22 of the water distributor 20 can be aligned and installed by extending the flange 12 into the outlet 22, avoiding water leakage caused by misalignment of the water inlet 11 and the outlet 22 due to installation errors. At the same time, it can achieve quick installation and improve the accuracy and efficiency of assembly.
