[0002] Most dishwashers currently do not have a water tank structure; they only have a breather for balancing the air pressure inside the dishwasher, calculating the amount of water entering, and serving as a drainage channel. Moreover, the breather does not have the function of reducing the energy consumption of the dishwasher.

[0003] Therefore, it is indeed necessary to improve existing technologies to address their shortcomings. Utility Model Content:

[0005] This utility model adopts the following technical solution: a water tank structure that can reduce the washing energy consumption of a dishwasher, including an upper cover and a lower cover installed together with the upper cover. The lower end of the lower cover is equipped with a water tank outlet pipe, a tap water inlet pipe, a first drain pipe, a second drain pipe, and a water tank outlet solenoid valve. A drain channel is connected between the first drain pipe and the second drain pipe. A water inlet channel is formed on the lower cover above the drain channel. A flow meter is installed on the lower cover between the tap water inlet pipe and the water inlet channel. The first drain pipe is connected to the dishwasher's drain pump. The second drain pipe extends to the outside of the dishwasher. A water tank storage channel is formed between the water tank outlet pipe and the water inlet channel. A water hole is formed on the side wall of the water tank storage channel above the water tank outlet pipe. The water hole is arranged opposite to the water tank outlet solenoid valve.

[0006] Furthermore, an inner liner vent is formed on the lower cover above the flow meter.

[0007] Furthermore, a water tank vent is formed at the upper end of the lower cover.

[0013] To further understand the contents of this utility model, a more detailed description is provided below with reference to the accompanying drawings. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0014] This utility model relates to a water tank structure that reduces the washing energy consumption of a dishwasher. It includes an upper cover 1 and a lower cover 2 installed together with the upper cover 1. The lower end of the lower cover 2 is equipped with a spaced-apart water tank outlet pipe 20, a tap water inlet pipe 21, a first drain pipe 22, a second drain pipe 23, and a water tank outlet solenoid valve 5. A drain channel 24 connects the first drain pipe 22 and the second drain pipe 23. A water inlet channel 27 is formed on the lower cover 2 above the drain channel 24. A flow meter 3 is installed on the lower cover 2 between the tap water inlet pipe 21 and the water inlet channel 27. An inner tank vent 25 is formed on the lower cover 2 above the flow meter 3. A water tank vent 26 is formed at the upper end of the lower cover 2.

[0015] The first drain pipe 22 and the second drain pipe 23 are connected through the drain channel 24. The first drain pipe 22 is connected to the drain pump (not shown) of the dishwasher, and the second drain pipe 23 extends to the outside of the dishwasher.

[0016] A water tank storage channel 6 is formed between the water tank outlet pipe 20 and the water inlet channel 27. A water hole 260 is formed on the side wall of the water tank storage channel 6 above the water tank outlet pipe 20. The water hole 260 is set opposite to the water tank outlet solenoid valve 5.

[0017] A first through hole 4 is formed on the outer wall of the dishwasher, opposite to the inner tank vent 25, and a second through hole 7 is formed on the outer wall of the dishwasher, opposite to the water tank vent 26. When the dishwasher is heated, the heat inside the dishwasher can be transferred to the water tank 6 through the first through hole 4 and the inner tank vent 25. Then, through a small hole (not shown) at the upper end of the water tank, the air pressure inside the water tank and the dishwasher inner tank is balanced with the external air pressure.

[0018] The water tank structure of this utility model can reduce the washing energy consumption of dishwashers. Its working principle is as follows:

[0019] During the dishwasher's cold rinse cycle, water continuously flows into the tap water inlet pipe. The flow meter calculates the water volume in the tank, and simultaneously, the water tank outlet solenoid valve 5 opens, allowing water to flow through the outlet solenoid valve 5 and the water tank outlet pipe 20 into the dishwasher's inner tub. Once all the water in the tank has entered the inner tub, the outlet solenoid valve 5 closes, and the dishwasher begins its cold rinse. Simultaneously, tap water is introduced through the tap water inlet pipe 21 into the water tank's storage area. Because the ambient temperature for dishwasher energy efficiency testing is higher than the tap water temperature, the water in the tank and the external environment can exchange heat, raising the water temperature in the tank. After the cold rinse cycle ends and the water is drained, the water tank inlet solenoid valve 5 opens, allowing the water heated by the external environment to enter the dishwasher's inner tub for the main hot rinse, reducing the heating time and lowering energy consumption.

[0020] During the main hot wash phase, when the water reaches the set temperature, the tap water inlet pipe supplies water to the water tank storage channel 6. At this time, the water outlet solenoid valve 5 is closed. Before the main hot wash ends, the water in the tank will be heated by the high temperature radiation of the dishwasher's main hot wash.

[0021] During the cold rinsing stage, after the main hot wash is completed and drained, the inlet solenoid valve 5 is opened, and part of the heated water in the tank enters the inner tank through the inlet solenoid valve 5 and the water outlet pipe 20 for cold rinsing.

[0022] During the hot rinsing stage, after the cold rinsing is completed and drained, the inlet solenoid valve 5 is opened, and the heated water tank stores water. Another part enters the inner tank through the inlet solenoid valve 5 and the water tank outlet pipe 20. At this time, the water temperature entering the inner tank is the water heated by the main hot rinsing stage, which can reduce the heating time of the heating components in the hot rinsing stage, thereby reducing the heating time of the heating components in the hot rinsing stage and achieving the effect of reducing energy consumption.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
