[0027] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where 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 by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0028] As Figures 1 to 5, The water tank 10 according to an embodiment of the present utility model is for a dishwasher. The water tank 10 includes a first water storage part 101 and a second water storage part 102. The first water storage part 101 is arranged in the vertical direction, and the second water storage part 102 is connected to the upper end of the first water storage part 101 and extends along the thickness direction of the water tank 10. The first water storage part 101 is provided with a first water storage space 1011, and the second water storage part 102 is provided with a second water storage space 1021. The first water storage space 1011 and the second water storage space 1021 are communicated. The first water storage space 1011 and the second water storage space 1021 constitute the water storage space of the water tank 10, which can increase the volume inside the water tank 10 to increase the water storage capacity of the water tank 10. Among them, the first water storage part 101 can be arranged on the side wall of the water tank 10, and the second water storage part 102 can be arranged above the water tank 10, so that the space above the inner liner can be used for water storage, thereby improving the space utilization rate of the dishwasher.

[0029] The water tank 10 according to an embodiment of the present utility model can use the first water storage part 101 and the second water storage part 102 for water storage, increasing the water storage space and volume of the water tank 10.

[0030] In addition, in some embodiments of the present utility model, the first water storage part 101 can be arranged on the side wall of the inner liner, and the second water storage part 102 can be arranged on the top wall of the inner liner. Among them, the second water storage part 102 can be supported on the top wall of the inner liner. In this way, the inner liner can be used to provide support for the water tank 10, which can increase the strength of the connection structure between the inner liner and the water tank 10, thereby improving the stability of the dishwasher.

[0031] Such as Figures 1 to 3 , in some embodiments, the water tank 10 is provided with an anti-siphon flow path, and the anti-siphon flow path communicates with the top of the second water storage space 1021. The anti-siphon flow path can be used to balance the internal and external air pressures of the water tank 10. When replenishing water in the water storage space, the air in the water storage space can be sent out through the anti-siphon flow path to facilitate the rapid replenishment of the water tank 10; when discharging water from the water storage space, the anti-siphon flow path can achieve the air pressure balance between the water storage space and the external space of the water tank 10 to facilitate the discharge of water from the water tank 10.

[0032] Optionally, the water tank 10 is provided with an inner liner interface 106 for connecting to the inner liner. The anti-siphon flow path includes an overflow flow path 103. One end of the overflow flow path 103 communicates with the top of the water storage space, and the other end communicates with the inner liner interface 106. Through the overflow flow path 103, it is convenient to achieve the internal and external air pressure balance of the water storage space, convenient for the water inlet and outlet of the water tank 10, and convenient for the use of the water tank 10. In addition, when the water inlet valve is damaged and water cannot stop flowing into the water storage space, the excess water introduced into the water tank 10 can be discharged through the anti-siphon flow path to the inner liner interface 106 and sent into the inner liner through the inner liner interface 106 to avoid excessive water pressure inside the water tank 10 and avoid the water introduced into the water tank 10 from overflowing, improving the stability and safety of the dishwasher.

[0033] Optionally, the water tank 10 is provided with a vent 1043 for connecting to the atmosphere. The anti-siphon flow path further includes a ventilation flow path 104, and the ventilation flow path 104 communicates with the overflow flow path 103 and the vent 1043. Through the vent 1043, it is further convenient to achieve the air pressure balance inside and outside the water storage space, facilitate the inlet and outlet of the water tank 10, and improve the stability and safety of the dishwasher.

[0034] Specifically, when replenishing water in the water storage space, the air in the water storage space can be discharged into the inner tank through the inner tank interface 106, or discharged into the external space of the water tank 10 through the vent 1043. In addition, when the water inflow in the water storage space is too large, it will be sent into the inner tank through the overflow flow path 103 from the inner tank interface 106, avoiding water leakage of the dishwasher and improving the stability and safety of the dishwasher; when draining water from the water storage space, the anti-siphon flow path can achieve the air pressure balance between the water storage space and the external space of the water tank 10, facilitating the draining of the water tank 10. When draining water from the water storage space, using the overflow flow path 103 and the ventilation flow path 104 to balance the internal and external air pressures of the water tank 10 can also use the ventilation flow path 104 to balance the air pressure of the inner tank, thereby further improving the stability of the dishwasher.

[0035] In addition, in the present utility model, the anti-siphon flow path communicates with the top of the second water storage space 1021. Only when the water level in the water tank 10 reaches the top of the second water storage space 1021, the water in the water tank 10 will overflow from the anti-siphon flow path. Therefore, both the first water storage space 1011 and the second water storage space 1021 of the water tank 10 can be filled with water, which can further increase the water storage level and water storage capacity in the water tank 10.

[0042] Among them, the second branch 1032 extends in the up and down direction. The upper end of the second branch 1032 communicates with the first branch 1031, and the lower end communicates with the inner tank interface 106. After the water in the water tank 10 overflows to the first branch 1031, it can flow into the inner tank interface 106 through the second branch 1032, which is convenient for the water flow to circulate. In addition, the ventilation flow path 104 includes a third branch 1041. The third branch 1041 extends along the width direction of the water tank 10, and one end communicates with the first branch.

[0043] At least one second baffle rib 132 is provided inside the second branch 1032, and there is a gap between at least one second baffle rib 132 and the inner wall surface of the second branch 1032. The second baffle rib 132 can limit the backflow of water in the inner tank. For example, when the water in the inner tank splashes onto the inner tank interface 106, the splashed water can be restricted from flowing into the water tank 10 under the blocking action of the second baffle rib 132, improving the stability of the dishwasher.

[0044] Optionally, at least a part of the first branch 1031 extends in the vertical direction, and at least one third baffle rib 133 is provided inside.
