Detailed Implementation

[0041] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0042] As shown in Figures 1 to 3, the water tank 3 according to an embodiment of this application is used in a dishwasher. The water tank 3 is provided with a water storage space 301, which can be used for temporary water storage and can treat the water used for washing to reduce the water treatment time during the washing process. For example, the water tank 3 can be used to preheat or disinfect the water. In addition, the water tank 3 is also provided with a water replenishment path 8 and an anti-siphon path. The water replenishment path 8 connects to the top of the water storage space 301, and the anti-siphon path connects the top of the water storage space 301 and the external space of the water tank 3. Water can be replenished to the water storage space 301 through the water replenishment path 8. When water is replenished to the water storage space 301, the air in the water storage space 301 can be discharged through the anti-siphon path to facilitate rapid water replenishment to the water tank 3. When water is discharged from the water storage space 301, the anti-siphon path can achieve air pressure balance between the water storage space 301 and the external space of the water tank 3 to facilitate water discharge from the water tank 3.

[0043] According to the embodiments of this application, the water tank 3 is provided with an anti-siphon flow path, which facilitates water inlet and outlet of the water tank 3, thereby facilitating the use of the dishwasher and improving its practicality and stability.

[0044] As shown in Figures 1 to 3, in some embodiments, the water tank 3 is provided with an inner tank interface 5 for connecting to the inner tank 40. The anti-siphon flow path includes an overflow flow path 302, one end of which is connected to the top of the water storage space 301, and the other end is connected to the inner tank interface 5. Through the overflow flow path 302, the internal and external air pressure balance of the water storage space 301 can be easily achieved, facilitating the inlet and outlet of water in the water tank 3 and making the water tank 3 easier to use. In addition, when the water inlet valve 19 is damaged, causing the water supply flow path 8 to be unable to stop from entering the water storage space 301, the excess water entering the water tank 3 can be discharged to the inner tank interface 5 through the anti-siphon flow path and sent into the inner tank 40 through the inner tank interface 5, so as to avoid excessive water pressure in the water tank 3 and prevent water entering the water tank 3 from overflowing, thereby improving the stability and safety of the dishwasher.

[0045] Optionally, the water tank 3 is provided with a vent 3031 for connecting to the atmosphere, and the anti-siphon flow path also includes a ventilation path 303, which connects the overflow flow path 302 and the vent 3031. The vent 3031 further facilitates the balance of internal and external air pressure in the water storage space 301, facilitates the inlet and outlet of the water tank 3, and improves the stability and safety of the dishwasher.

[0046] Specifically, when water is added to the water storage space 301, air inside the water storage space 301 can be discharged into the inner tank 40 through the inner tank interface 5, or discharged into the external space of the water tank 3 through the vent 3031. Furthermore, when the water intake of the water storage space 301 is too large, it will be fed into the inner tank 40 through the overflow path 302 from the inner tank interface 5, preventing water leakage from the dishwasher and improving the stability and safety of the dishwasher. When water is drained from the water storage space 301, the anti-siphon path can achieve air pressure balance between the water storage space 301 and the external space of the water tank 3, facilitating water draining from the water tank 3. During water draining from the water storage space 301, the overflow path 302 and the airflow path 303 balance the internal and external air pressure of the water tank 3, and the airflow path 303 can also balance the air pressure of the inner tank 40, thereby further improving the stability of the dishwasher.

[0047] Optionally, the overflow path 302 includes a first branch 3021 and a second branch 3022. One end of the first branch 3021 is connected to the top of the water storage space 301, and the other end is connected to the airflow path 303 and the second branch 3022. The other end of the first branch 3021 is provided with a first baffle 3023, which is configured to guide the flow towards the second branch 3022. The second branch 3022 is connected to the inner tank interface 5. The overflow path 302 and the airflow path 303 are configured as a three-way structure. The first baffle 3023 can guide the water flow and enable airflow. Specifically, when the water volume in the water tank 3 is too large, the water in the water tank 3 will flow into the first branch 3021 and, under the guidance of the first baffle 3023, will flow into the second branch 3022, thus preventing the water in the water tank 3 from flowing into the airflow path 303.

[0048] The second branch 3022 extends vertically, with its upper end connected to the first branch 3021 and its lower end connected to the inner tank interface 5. Water overflowing from the water tank 3 into the first branch 3021 can then flow through the second branch 3022 into the inner tank interface 5, facilitating water flow. Additionally, the airflow path 303 includes a third branch 3032, which extends along the width of the water tank 3 and has one end connected to the first branch. By designing the third branch 3032 to extend horizontally and the second branch 3022 to extend vertically, water flowing into the other end of the first branch 3021 flows more easily downwards and is less likely to flow horizontally, thus flowing smoothly into the second branch 3022 while restricting water flow into the third branch 3032. The first baffle 3023 is connected to the other end of the first branch 3021 on the side near the third branch 3032, and is inclined downward and away from the third branch 3032. This facilitates the diversion of water overflowing from the water tank 3, and also helps to prevent backflow of water in the inner tank 40, thus improving the stability of the anti-siphon flow path.

[0049] At least one second baffle 3024 is provided within the second branch 3022, and a gap is provided between the at least one second baffle 3024 and the inner wall surface of the second branch 3022. The second baffle 3024 can restrict the backflow of water in the inner tank 40. For example, when water in the inner tank 40 splashes onto the inner tank interface 5, the stopping action of the second baffle 3024 can prevent the splashed water from flowing into the water tank 3, thereby improving the stability of the dishwasher.

[0050] Optionally, at least a portion of the first branch 3021 extends in the vertical direction, and the interior of the first branch 3021 is provided with at least one third baffle 3025, wherein the third baffle 3025 is configured to connect one side of the first branch 3021 and extend downward and inclined toward the other side of the first branch 3021.

[0051] In some embodiments, the top surface of the water storage space 301 is provided with a first connecting port 3026 and a second connecting port 3027. The water supply path 8 connects to the first connecting port 3026, and the anti-siphon flow path connects to the second connecting port 3027. This can increase the water level that can flow into the water storage space 301 and increase the water storage capacity of the water storage space 301. The first connecting port 3026 and the second connecting port 3027 are respectively located on opposite sides of the top surface of the water storage space 301 along the width direction. This can optimize the distribution of flow paths and connecting ports within the water tank 3, thereby simplifying the structure of the water tank 3 and improving the stability of the dishwasher.

[0052] In some embodiments of this application, the water tank 3 is provided with a vent 3031 for connecting to the atmosphere, and the anti-siphon flow path also includes a flow path 303, which connects the water storage space 301 and the vent 3031. The air pressure inside and outside the water storage space 301 can be balanced through the vent 3031, facilitating the inlet and outlet of water in the water storage space 301.

[0053] Optionally, the air passage 303 includes a third branch 3032 and a fourth branch 3033. The third branch 3032 extends along the width of the water tank 3 and connects to the water storage space 301 at one end. The fourth branch 3033 extends vertically and connects to the third branch 3032 at its upper end. The fourth branch 3033 and the vent 3031 are located on the side edge of the water tank 3. By placing the vent 3031 on the side edge of the water tank 3, when the water tank 3 is stacked on the side wall of the inner liner 40, the inner liner 40 can be prevented from affecting the connectivity of the vent 3031.

[0054] In addition, a recessed groove is provided on the side edge of the water tank 3, and the vent 3031 is located in the recessed groove, which further avoids the inner tank 40 or the outer shell of the dishwasher from affecting the ventilation performance of the vent 3031, and facilitates the balance of internal and external air pressure in the water tank 3.

[0055] Vent 3031 includes a first through hole located at the upper end of the fourth branch 3033; and / or, vent 3031 includes a grid-like second through hole located at the lower end of the fourth branch 3033. This can improve the ventilation performance of vent 3031 and prevent pressure imbalance caused by blockage of a single vent 3031.

[0056] Optionally, the first end of the third branch is connected to the fourth branch, and the second end is connected to the water storage space, with the first end of the third branch being higher than the second end.

[0057] Optionally, the third branch is located at the top of the water tank, and the vent includes a first through hole located at the upper end of the fourth branch. This can shorten the length of the air path between the water storage space and the vent.

[0058] In some embodiments, the water tank 3 is also provided with a drainage channel 13, and the anti-siphon flow path also includes a drainage flow path 131, the lower end of which is connected to the drainage channel 13, and the upper end of which is connected to the air passage 303.

[0059] Optionally, a one-way structure 43 is provided between the drainage path 131 and the ventilation path 303. The one-way structure 43 is configured to allow unidirectional flow from the drainage path 131 to the ventilation path 303. This can prevent siphoning during drainage and facilitate the emptying of the drainage channel 13.

[0060] Optionally, the first end of the third branch is connected to the fourth branch, and the unidirectional structure 43 is lower than the first end of the third branch.

[0061] In some embodiments, the water tank 3 is also provided with a water inlet passage 12, and a one-way valve 11 is connected in series in the water inlet passage 12. In addition, the water inlet passage 12 is separated from the water storage space 301. The one-way valve 11 can realize the pressure imbalance in the water inlet passage 12.

[0062] In addition, the water inlet flow path 12 in the related technology is provided with an arc-shaped anti-siphon structure. This anti-siphon structure connects to the internal space of the water tank 3, which causes the water level in the water storage space 301 to not exceed the anti-siphon structure, thus increasing the water level in the water tank 3.

[0063] As shown in Figures 1 to 4, the dishwasher according to an embodiment of this application includes: an inner tank 40 and the aforementioned water tank 3, wherein the inner tank 40 is provided with a washing space.

[0064] In some embodiments, the water tank 3 is located on the outer side wall of the inner liner 40; and / or, the anti-siphon flow path is connected to the inner liner 40. Optionally, the aforementioned inner liner interface 5 is connected to the inner liner 40.

[0065] As shown in Figures 1 to 4, the dishwasher also includes a water cup 36, which is used for temporary water storage and filtering of washing water. During the use of the dishwasher, water used in the washing process can be stored in the water cup 36 for convenient centralized discharge of washing water and collection of washing residue. It also includes a water tank 3, which has a water storage space. This water storage space can be used to store water, facilitating the operation of the dishwasher and improving washing efficiency and effectiveness. Additionally, it may include a washing chamber, which has a washing space for placing dishes to be washed. The water cup 36 can be located at the bottom of the washing chamber and connected to the washing space.

[0066] Additionally, the dishwasher may include a first switching valve 24, one end of which is connected to the outlet of the water tank 3. The first switching valve 24 can be used to control the opening and closing of the outlet of the water tank 3. It also includes a water distribution structure 25, which has a first connection port 21, a second connection port, and a third connection port. The first connection port 21 connects to the other end of the first switching valve 24 and the water inlet path 12; the second connection port connects to the inlet of the water tank 3; and the third connection port connects to the inlet of the water cup 36. The water flow direction can be controlled by the sorting structure.

[0067] According to the embodiments of this application, the dishwasher can adjust the water flow direction through the linkage of the first switching valve 24 and the water distribution structure 25. For example, the combination of the first switching valve 24 and the water distribution structure 25 can control the water source to supply water to the water cup 36 or control the water source to replenish water to the water tank 3; it can also control the water tank 3 or the water source to supply water to the water cup 36 to meet different water needs. This makes the dishwasher more convenient to use.

[0068] In addition, the water tank 3 in this application can be stacked on the side wall, bottom wall or top wall of the washing tank, etc.

[0069] As shown in Figures 1 to 4, in some embodiments, the dishwasher has at least two operating modes. The water distribution structure 25 is configured to selectively connect the first connection port 21 to the second and third connection ports according to the at least two operating modes. Thus, the operating modes of the dishwasher can be switched by adjusting the water distribution structure 25, facilitating the use of the dishwasher.

[0070] Optionally, the dishwasher in this application may include, but is not limited to, the following operating modes.

[0071] In some examples, the dishwasher has a first operating mode in which the first switch valve 24 is closed and the first connection port 21 and the second connection port are connected to replenish water to the water tank 3. In the first operating mode, after the water from the inlet flow path 12 reaches the first connection port 21, the water will flow to the second connection port, thereby replenishing water to the water tank 3. A water level sensor can be installed in the water tank 3 or a flow sensor can be installed in the inlet flow path 12. When the water level in the water tank 3 reaches the preset water level, the inlet flow path 12 will be closed, thus completing the replenishment of water to the water tank 3.

[0072] In some examples, the dishwasher also has a second operating mode. In this mode, the first switch valve 24 is closed, and the first connection port 21 and the third connection port are connected for replenishing water to the water cup 36. In this second operating mode, after the water from the inlet flow path 12 reaches the first connection port 21, the water will flow to the third connection port, thereby supplying water to the water cup 36. A flow sensor can be installed in the inlet flow path 12. When the water level in the water cup 36 reaches a preset level, the inlet flow path 12 will be closed, thus completing the water supply to the water cup 36.

[0073] In some examples, the dishwasher also has a third operating mode. In this mode, the first switch valve 24 is open, and the first connection port 21 and the third connection port are connected to supply water to the water cup 36 through the water tank 3. In the third operating mode, the water inlet path 12 is closed, and the water in the water tank 3 flows out from the outlet, passes through the first switch valve 24, flows to the first connection port 21, and then flows to the water cup 36 through the third connection port, thus supplying water to the water cup 36. When the water level in the water cup 36 reaches the preset water level, the first switch valve 24 can be closed, thereby completing the water supply to the water cup 36.

[0074] In some embodiments, the dishwasher also includes a water softener 20, which is connected between the water inlet path 12 and the first connection port 21 to supply softened water to the first connection port 21. By providing the water softener 20, softened water can be supplied to improve the washing efficiency and effect of the dishwasher. In addition, since the water softener 20 is located before the first connection port 21, it can supply softened water to the water tank 3 and the water cup 36, achieving full soft water washing.

[0075] In some embodiments, the water distribution structure 25 is installed in the water softener 20; and / or, at least a portion of the piping between the water distribution structure 25 and the water tank 3 is integrated into the water softener 20; and / or, at least a portion of the piping between the water distribution structure 25 and the water cup 36 is integrated into the water softener 20. This facilitates the integration of the water softener 20, simplifies the structure of the dishwasher, facilitates dishwasher maintenance, and optimizes the space utilization of the dishwasher.

[0076] In some embodiments, the water inlet path 12 is integrated into the water tank 3, the water tank 3 is connected to the water softener 20, and the water inlet path 12 communicates with the softened water flow channel within the water softener 20; and / or, the water softener 20 is provided with a water source interface, the water inlet path 12 is integrated into the water tank 3, the water tank 3 is connected to the water softener 20, and the water inlet path 12 communicates with the water source interface. The connection between the water tank 3 and the water softener 20 allows the flow path within the water tank 3 to communicate with the flow path within the water softener 20, facilitating component integration and dishwasher assembly, thereby improving the dishwasher's assembly efficiency and stability.

[0077] Optionally, the water tank 3 is provided with at least one water tank 3 interface, and the water softener 20 is provided with at least one water softener 20 interface. The water tank 3 is connected to the water softener 20, and at least one water tank 3 interface and at least one water softener 20 interface are mated. This simplifies the assembly structure of the water softener 20 and the water tank 3, thereby further simplifying the frame of the dishwasher.
