[0027] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1 to 3 According to an embodiment of the present invention, the water tank 3 is used in a dishwasher. The water tank 3 has a water storage space 301. The water storage space 301 can be used to temporarily store water and process the water used for washing, thereby reducing water processing time during the washing process. For example, the water can be preheated and disinfected through the water tank 3. Furthermore, the water tank 3 is provided with a water replenishment flow path 8 and an anti-siphon flow path. The water replenishment flow path 8 connects to the top of the water storage space 301, while the anti-siphon flow path connects the top of the water storage space 301 with the space outside the water tank 3. Water can be replenished into the water storage space 301 through the water replenishment flow path 8. During replenishment, air within the water storage space 301 can be discharged through the anti-siphon flow path, facilitating rapid replenishment of the water tank 3. When the water storage space 301 is drained, the anti-siphon flow path balances the air pressure between the water storage space 301 and the space outside the water tank 3, facilitating draining of the water tank 3.

[0029] According to the embodiment of the utility model, the water tank 3 is provided with an anti-siphon flow path, which can facilitate the water intake and draining of the water tank 3 and the water in and out of the water tank 3, thereby facilitating the use of the dishwasher and improving the practicality and stability of the dishwasher.

[0030] like 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. The overflow flow path 302 can facilitate the balance of air pressure inside and outside the water storage space 301, facilitate the flow of water in and out of the water tank 3, and facilitate the use of the water tank 3. In addition, when the water inlet valve 19 is damaged, making it impossible to stop the water replenishment flow path 8 from supplying water to the water storage space 301, excess water entering the water tank 3 can be discharged to the inner tank interface 5 through the anti-siphon flow path and then sent to the inner tank 40 through the inner tank interface 5, thereby preventing the water pressure in the water tank 3 from being too high and preventing the water entering the water tank 3 from overflowing, thereby improving the stability and safety of the dishwasher.

[0031] Optionally, the water tank 3 is provided with a vent 3031 for connecting to the atmosphere. The anti-siphon flow path further includes a vent flow path 303, which connects the overflow flow path 302 and the vent 3031. The vent 3031 can further facilitate the balance of air pressure inside and outside the water storage space 301, facilitate the inlet and outlet of the water tank 3, and improve the stability and safety of the dishwasher.

[0032] Specifically, when the water storage space 301 is replenished with water, the air in the water storage space 301 can be discharged into the inner tank 40 through the inner tank interface 5, or discharged into the space outside the water tank 3 through the vent 3031. Furthermore, when the water intake into the water storage space 301 is excessive, the air will be fed from the inner tank interface 5 into the inner tank 40 through the overflow flow path 302, preventing water leakage from the dishwasher and improving the stability and safety of the dishwasher. When the water storage space 301 is drained, the anti-siphon flow path can achieve air pressure balance between the water storage space 301 and the space outside the water tank 3, facilitating the draining of the water tank 3. When the water storage space 301 is drained, the overflow flow path 302 and the vent flow path 303 balance the air pressure inside and outside the water tank 3. The vent flow path 303 can also balance the air pressure in the inner tank 40, further improving the stability of the dishwasher.

[0033] Optionally, the overflow flow 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 ventilation flow path 303 and the second branch 3022. The other end of the first branch 3021 is provided with a first retaining rib 3023, which is configured to divert water toward the second branch 3022. The second branch 3022 is connected to the inner tank interface 5. The overflow flow path 302 and the ventilation flow path 303 are configured to form a three-way structure. The first retaining rib 3023 can guide the water flow and achieve airflow communication. Specifically, when the amount of water 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 diversion effect of the first retaining rib 3023, will be diverted to the second branch 3022, thereby preventing the water in the water tank 3 from being diverted to the ventilation flow path 303.

[0034] 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 port 5. This allows water within the water tank 3 to overflow into the first branch 3021 and then flow into the inner tank port 5 through the second branch 3022, facilitating water flow. Furthermore, the ventilation path 303 includes a third branch 3032, which extends along the width of the water tank 3 and connects to the first branch 3021 at one end. By extending the third branch 3032 horizontally and the second branch 3022 vertically, water entering the other end of the first branch 3021 is more likely to flow downward than horizontally, and will flow smoothly into the second branch 3022, limiting water flow into the third branch 3032. The first retaining rib 3023 is connected to the other end of the first branch 3021, near the third branch 3032, and is inclined downward and away from the third branch 3032. This facilitates the diversion of overflowing water from the water tank 3 and prevents the water in the inner tank 40 from flowing backward, thereby improving the stability of the anti-siphon flow path.

[0035] At least one second retaining rib 3024 is provided within the second branch 3022, with a gap formed between the at least one second retaining rib 3024 and the inner wall of the second branch 3022. The second retaining rib 3024 can prevent water in the inner container 40 from flowing back. For example, if water in the inner container 40 splashes onto the inner container interface 5, the second retaining rib 3024 can prevent the splashed water from flowing into the water tank 3, thereby improving the stability of the dishwasher.

[0036] Optionally, at least a portion of the first branch 3021 extends in the up-down direction, and at least one third rib 3025 is provided inside. The third rib 3025 is configured to connect one side of the first branch 3021 and extend obliquely downward and toward the other side of the first branch 3021.

[0037] In some embodiments, the top surface of the water storage space 301 is provided with a first communication port 3026 and a second communication port 3027. The water replenishment flow path 8 is connected to the first communication port 3026, and the anti-siphon flow path is connected to the second communication port 3027. This can increase the water level within the water storage space 301 and thereby increase the water storage capacity of the water storage space 301. The first communication port 3026 and the second communication port 3027 are located on opposite sides of the top surface of the water storage space 301 along the width direction. This allows for optimizing the distribution of the flow paths and communication ports within the water tank 3, simplifying the structure of the water tank 3 and improving the stability of the dishwasher.

[0038] In some embodiments of the present invention, the water tank 3 is provided with a vent 3031 for connecting to the atmosphere, and the anti-siphon flow path further includes a ventilation flow path 303, which connects the water storage space 301 and the vent 3031. The vent 3031 can balance the internal and external air pressures of the water storage space 301, facilitating the inflow and outflow of water into and out of the water storage space 301.

[0039] Optionally, the ventilation flow path 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 communicates with the water storage space 301 at one end. The fourth branch 3033 extends in the vertical direction and communicates with the third branch 3032 at its upper end. The fourth branch 3033 and the vent 3031 are provided at the side edge of the water tank 3. The vent 3031 can be provided at 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.

[0040] In addition, a sink groove is provided on the side edge of the water tank 3, and the vent 3031 is provided in the sink groove, which further prevents the inner tank 40 or the outer shell of the dishwasher from affecting the ventilation performance of the vent 3031, thereby facilitating the balance of the internal and external air pressures of the water tank 3.

[0041] The vent 3031 may include a first through hole located at the upper end of the fourth branch 3033, and / or a second through hole in a grid pattern located at the lower end of the fourth branch 3033. This can improve the ventilation performance of the vent 3031 and prevent internal and external pressure imbalance caused by blockage of a single vent 3031.

[0042] 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, and the first end of the third branch is higher than the second end.

[0043] Optionally, the third branch is provided at the upper portion of the water tank, and the vent includes a first through hole provided at the upper end of the fourth branch, thereby shortening the length of the air path between the water storage space and the vent.

[0044] In some embodiments, the water tank 3 is further provided with a drainage channel 13 , and the anti-siphon flow path further includes a drainage flow path 131 . The lower end of the drainage flow path 131 is connected to the drainage channel 13 , and the upper end is connected to the ventilation flow path 303 .

[0045] Optionally, a one-way structure 43 is provided between the drainage flow path 131 and the ventilation flow path 303. The one-way structure 43 is configured to conduct unidirectionally from the drainage flow path 131 to the ventilation flow path 303. This can prevent siphonage of drainage and facilitate emptying of the drainage channel 13.

[0046] Optionally, the first end of the third branch is connected to the fourth branch, and the one-way structure 43 is lower than the first end of the third branch.

[0047] In some embodiments, the water tank 3 further includes a water inlet flow path 12, which is connected with a one-way valve 11. In addition, the water inlet flow path 12 is separated from the water storage space 301. The one-way valve 11 can achieve pressure imbalance in the water inlet flow path 12.

[0048] In addition, in the related art, an arc-shaped anti-siphon structure is provided in the water inlet flow path 12, which is connected to the internal space of the water tank 3. This results in the water level in the water storage space 301 not being able to exceed the anti-siphon structure, thereby increasing the water level in the water tank 3.

[0049] like Figures 1 to 4 The dishwasher according to the embodiment of the present invention includes: an inner tank 40 and the aforementioned water tank 3, and the inner tank 40 is provided with a washing space.

[0050] In some embodiments, the water tank 3 is disposed outside the side wall of the inner container 40; and / or the anti-siphon flow path is connected to the inner container 40. Optionally, the inner container interface 5 is connected to the inner container 40.

[0051] like Figures 1 to 4The dishwasher also includes a water cup 36, which is used to temporarily store water and filter the wash water. During use, the water used in the wash process can be stored in the water cup 36 to facilitate centralized discharge of the wash water and collect residues during the wash process. It also includes a water tank 3, which has a water storage space that can be used to store water. This water storage facilitates the operation of the dishwasher, thereby improving the efficiency and effectiveness of washing. In addition, it can also include a washing box, which has a washing space within it for placing dishes to be washed, etc., wherein the water cup 36 can be placed at the bottom of the washing box and connected to the washing space.

[0052] The dishwasher may also include a first on-off valve 24, one end of which is connected to the outlet of the water tank 3 and can be used to control the opening and closing of the outlet of the water tank 3. The dishwasher also includes a water diversion structure 25 having a first connection port 21, a second connection port, and a third connection port. The first connection port 21 connects the other end of the first on-off valve 24 to 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 diversion structure.

[0053] The dishwasher according to the embodiment of the present invention can adjust the direction of water flow through the linkage of the first switch valve 24 and the water diversion structure 25. For example, the combination of the first switch valve 24 and the water diversion 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 use of the dishwasher more convenient.

[0054] In addition, the water tank 3 in the present invention can be stacked on the side wall, bottom wall or top wall of the washing box.

[0055] like Figures 1 to 4 In some embodiments, the dishwasher has at least two operating modes. The water diversion structure 25 is configured to control the first connection port 21 to selectively connect to the second and third connection ports according to the at least two operating modes. Thus, the operating mode of the dishwasher can be switched by adjusting the water diversion structure 25, thereby facilitating use of the dishwasher.

[0056] Optionally, the dishwasher in the present invention may include but is not limited to the following operating modes.

[0057] In some examples, the dishwasher has a first operating mode. In this first operating mode, the first on-off valve 24 is closed, and the first connection port 21 and the second connection port are connected for replenishing water into the water tank 3. In the first operating mode, after water from the water inlet flow path 12 reaches the first connection port 21, the water will flow to the second connection port, thereby replenishing the water tank 3. A water level sensor can be provided in the water tank 3, or a flow sensor can be provided in the water inlet flow path 12. When the water level in the water tank 3 reaches a preset level, the water inlet flow path 12 will be closed, thereby completing the water replenishment of the water tank 3.

[0058] In some examples, the dishwasher also has a second operating mode. In this second operating mode, first on / off valve 24 is closed, and first and third connecting ports 21 are connected for refilling cup 36. In this second operating mode, after water from water inlet path 12 reaches first connecting port 21, it flows to the third connecting port, thereby supplying water to cup 36. A flow sensor can be provided in water inlet path 12. When the water level in cup 36 reaches a preset level, water inlet path 12 is closed, completing the water supply to cup 36.

[0059] In some examples, the dishwasher further has a third operating mode. In this third operating mode, the first on-off valve 24 is open, and the first connection port 21 and the third connection port are connected, allowing water to be supplied to the water cup 36 through the water tank 3. In this third operating mode, the water inlet flow path 12 is closed, and water in the water tank 3 flows out of the outlet, passes through the first on-off valve 24, flows to the first connection port 21, and then flows to the water cup 36 through the third connection port, thereby supplying water to the water cup 36. When the water level in the water cup 36 reaches a preset level, the first on-off valve 24 can be closed, completing the water supply to the water cup 36.

[0060] In some embodiments, the dishwasher further includes a water softener 20, which is connected between the water inlet 12 and the first connection port 21 and is configured to supply softened water to the first connection port 21. The provision of the water softener 20 provides softened water, thereby improving the dishwasher's washing efficiency and effectiveness. Furthermore, the water softener 20, positioned before the first connection port 21, can supply softened water to the water tank 3 and the water cup 36, achieving fully soft water washing.

[0061] In some embodiments, the water diversion structure 25 is mounted on the water softener 20; and / or at least a portion of the piping between the water diversion structure 25 and the water tank 3 is integrated with the water softener 20; and / or at least a portion of the piping between the water diversion structure 25 and the water cup 36 is integrated with the water softener 20. This facilitates the integration of the water softener 20, simplifies the structure of the dishwasher, facilitates dishwasher maintenance, and optimizes space utilization.

[0062] In some embodiments, the water inlet flow path 12 is integrated into the water tank 3, which is connected to the water softener 20, and the water inlet flow path 12 communicates with the soft water flow path within the water softener 20. Alternatively, the water softener 20 is provided with a water source interface, and the water inlet flow path 12 is integrated into the water tank 3, which is connected to the water softener 20, and the water inlet flow path 12 communicates with the water source interface. The connection between the water tank 3 and the water softener 20 allows the flow paths within the water tank 3 to communicate with the flow paths within the water softener 20, facilitating component integration and dishwasher assembly, thereby improving dishwasher assembly efficiency and stability.

[0063] 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 the at least one water tank 3 interface is docked with the at least one water softener 20 interface. This simplifies the assembly structure of the water softener 20 and the water tank 3, thereby further simplifying the structure of the dishwasher.
