In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0030] See Figures 1-8 A dishwasher water tank structure includes a tank body 1, a first water passage 2 on the tank body 1, a water inlet 4 communicating with the inner cavity of the tank body 1 and a liquid outlet 9 communicating with the dishwasher, and a first switch valve 8 for opening and closing the water inlet 4 of the first water passage 2.

[0031] When the inlet 4 of the first water channel 2 is closed, the liquid enters the dishwasher directly through the first water channel 2 of the cabinet 1.

[0032] When the inlet 4 of the first water passage 2 is opened, the liquid enters the tank 1 through the inlet 4 of the first water passage 2, so as to store the liquid in the tank 1.

[0033] By configuring a first water path 2, a water inlet 4, a liquid outlet 9, and a first switching valve 8, a flexible water path control method is provided for the dishwasher's water tank. During the dishwasher's workflow, when in the pre-wash and cold rinse stages and hot water is not required, the water inlet 4 of the first water path 2 can be closed, allowing the liquid to enter the dishwasher directly through the first water path 2 without passing through the water tank storage, adapting to the temperature requirements of different washing stages. During the main wash and hot rinse stages, the water inlet 4 of the first water path 2 is opened, allowing the liquid to enter the tank 1 for storage. The residual heat generated during dishwasher operation preheats the liquid, shortening the heating time during subsequent heating, significantly improving the dishwasher's energy efficiency, and optimizing the water resource utilization efficiency of the entire washing process. This makes the water tank system more functional and better meets the diverse operational needs of the dishwasher.

[0034] The housing 1 is provided with a second water passage 3, the second water passage 3 is provided with an output end 6 connected to the liquid outlet end 9, and the housing 1 is provided with a second switch valve 7 for opening and closing the output end 6 of the second water passage 3.

[0035] When the output end 6 of the second water channel 3 is opened, the liquid in the housing 1 enters the dishwasher along the output end 6 of the second water channel 3 and the liquid outlet end 9 of the first water channel 2.

[0036] When the dishwasher is in the main wash and hot rinse stages and requires preheated liquid from the water tank, the output end 6 of the second water path 3 is opened. The liquid stored in the tank 1 can then smoothly enter the dishwasher through the output end 6 of the second water path 3 and the liquid outlet 9 of the first water path 2, forming a dedicated channel for transporting the preheated liquid. This design ensures that the preheated liquid in the water tank is stably and efficiently delivered to the dishwasher for heating and use. Independent control of the second water path 3 allows for more precise control of the flow rate and velocity of the preheated liquid, resulting in better washing performance during the main wash and hot rinse stages, further enhancing the overall performance and user experience of the dishwasher.

[0037] The housing 1 is provided with a mounting cavity 10 for installing the second switch valve 7. The mounting cavity 10 is provided with a notch 11 for connecting the liquid outlet 9 of the first water circuit 2. The output end 6 of the second water circuit 3 is open, and the notch 11 is connected to the output end 6 of the second water circuit 3.

[0038] The mounting cavity 10 provides a stable mounting space for the second switching valve 7, ensuring its fixed position during operation. The notch 11 allows liquid to flow smoothly from the output end 6 of the second water circuit 3 to the outlet end 9 of the first water circuit 2 when the output end 6 of the second water circuit 3 is open, via the notch 11. This design simplifies the water circuit connection, reducing additional connectors and complex piping layout.

[0039] The second switching valve 7 includes a second driver 12 and a second sealing sleeve 13 that is drivenly connected to the output shaft of the second driver 12. The outer side of the second sealing sleeve 13 is in sealing contact with the inner wall of the mounting cavity 10. The output shaft of the second driver 12 drives the second sealing sleeve 13 to open the output end 6 of the second water passage 3. The second sealing sleeve 13 is in a compressed state and remains in sealing contact with the inner wall of the mounting cavity 10.

[0040] In this technical solution, the second driver 12 is a wax motor.

The housing of the second driver 12 is fixed to the outside of the box 1 by screws.

[0041] The housing 1 is provided with an inlet 5 for connecting to the water outlet of the dishwasher water softener.

[0042] Softened water is introduced into the water tank. During the dishwasher's operation, using softened water effectively reduces limescale buildup, protects internal components such as heating elements and pipes, and extends the dishwasher's lifespan.

[0043] The housing 1 is provided with an assembly cavity 14 for installing a first switch valve 8. The first switch valve 8 includes a first driver 15 and a first sealing sleeve 16 that is drivenly connected to the output shaft of the first driver 15. The outer side of the first sealing sleeve 16 is sealed against the inner wall of the assembly cavity 14. The output shaft of the first driver 15 drives the first sealing sleeve 16 to open the water inlet 4 of the first water passage 2. The first sealing sleeve 16 is in a compressed state and remains sealed against the inner wall of the assembly cavity 14.

[0044] Assembly cavity 14 provides a stable installation environment for the first switching valve 8, ensuring that the first switching valve 8 will not shift during operation and guaranteeing the accuracy of water circuit control. The output shaft of the first actuator 15 drives the first sealing sleeve 16 to open or close the water inlet 4 of the first water circuit 2. When open, the first sealing sleeve 16 is in a compressed state and seals against the inner wall of the assembly cavity 14, effectively preventing liquid leakage during water inlet and ensuring the sealing and safety of the water circuit system. When the water inlet 4 of the first water circuit 2 is closed, one end of the first sealing sleeve 16 can tightly fit against the outside of the water inlet 4 of the first water circuit 2, preventing liquid from entering the water tank.

[0045] In this technical solution, the first driver 15 is a wax motor. During the extension and retraction of the output shaft of the first driver 15, it drives the first sealing sleeve 16 to open and close the water inlet 4 of the first water passage 2. The first sealing sleeve 16 is provided with a first telescopic sealing section and a first fixing section that abuts against the inner wall of the mounting cavity 10. The housing of the first driver 15 is fixed to the outside of the box 1 by screws.

[0046] In this technical solution, when the first sealing sleeve 16 is in the state of sealing the water inlet end 4 of the first water channel 2, the first sealing sleeve 16 and the inner wall of the assembly cavity 14 are left with a water inlet gap so that liquid can enter the liquid outlet end 9 of the first water channel 2.

[0047] The housing 1 is provided with a connection end 18 for connecting to the dishwasher breather 17. When the air pressure inside the housing increases, excess gas can be discharged through the breather via the connection end 18 to the dishwasher breather 17.

[0048] The housing 1 is provided with a channel 19 for balancing the air pressure inside and outside the housing 1. One end of the channel 19 is connected to the inner cavity of the housing 1, and the other end of the channel 19 is connected to the dishwasher breather 17.

[0049] The housing 1 is equipped with a pressure regulating structure for adjusting the internal air pressure of the water tank. The pressure regulating structure includes a hidden channel 28. A drain port 20 is provided between the hidden channel 28 and the inner side of the housing 1. The pressure regulating structure and the drain port 20 are respectively connected to the dishwasher breather 17 through the connecting end 18 and the channel 19.

[0050] The inner cavity of the box 1 is divided into two independently spaced first cavities 29 and second cavities 30 by a channel 19. A hidden channel 28 is provided between the first cavities 29 and the second cavities 30, and the first cavities 29 and the second cavities 30 are connected by the hidden channel 28 so as to balance the air pressure of the first cavities 29 and the second cavities 30 when the water inlet of the box 1 is adjusted.

[0051] The housing 1 includes a front shell 21 and a bottom shell 22. A first water passage 2 and a second water passage 3 are provided between the front shell 21 and the bottom shell 22, as well as a first switch valve 8 and a second switch valve 7 for switching the corresponding water passages.

[0052] The combination of the front shell 21 and the bottom shell 22 facilitates the assembly and disassembly of the water tank, reducing production and maintenance costs. Secondly, integrating the water circuit and the on / off valve between the front shell 21 and the bottom shell 22 makes the water tank structure more compact, making efficient use of space, reducing the overall volume of the water tank, and contributing to the optimized layout of the dishwasher's internal space.

[0053] In this technical solution, a sealing ring can be provided between the front shell 21 and the bottom shell 22 to prevent liquid from leaking through the installation gap between the front shell 21 and the bottom shell 22.

[0054] In this technical solution, the housing 1 is provided with a first liquid inlet channel 25 and a second liquid inlet channel 26 that connect the water inlet end 4 of the first water channel 2. A partition is provided between the first liquid inlet channel 25 and the second liquid inlet channel 26. One end of the partition is provided with a flow limiting notch 27. The outlet end of the second liquid inlet channel 26 connects to the inner cavity of the housing 1. When the water inlet end 4 of the first water channel 2 is opened, the liquid output by the water softener enters the inner cavity of the housing 1 through the water inlet end 4 of the first water channel 2, the first liquid inlet channel 25, and the second liquid inlet channel 26.

[0055] In this technical solution, the inner cavity of the box 1 includes a first cavity 29 and a second cavity 30. Two spaced-apart partitions are provided between the first cavity 29 and the second cavity 30, forming a channel 19 between the two partitions. A clearance is left between one end of the two partitions and the inner side of the box 1. One end of the hidden channel 28 is connected to the two partitions, and a clearance is left on the back of the hidden channel 28 so that the first cavity 29 and the second cavity 30 can be connected through the clearance.

[0056] In this technical solution, the top of the two partition blocks inside the box 1 is provided with a horizontally extending dark channel 28. A drain port 20 is left between the horizontally extending dark channel 28 and the inner side of the box 1. When the front shell 21 and the bottom shell 22 are assembled, if the air pressure inside the box 1 is too high, the gas will enter the channel 19 along the drain port 20.

[0057] The first water path 2 and the second water path 3 form a parallel water path system. Through the coordinated control of the first switch valve 8 and the second switch valve 7, three working modes are realized: direct flow mode (directly enters the dishwasher), water storage mode (stored in the water tank), and drainage mode (stored water absorbs heat before entering the dishwasher).
