It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

In order to solve the above-mentioned technical problems, please refer to fig. 1 to 4, the present application provides a dishwasher 20, which can reduce energy consumption in a washing process and save energy.

The dishwasher comprises an inner container 10, a preheating water tank 20 and a washing connecting pipeline 60 for connecting the inner container 10 and the preheating water tank 20, wherein the inner container 10 is arranged adjacent to the preheating water tank 20, the preheating water tank 20 can store and preheat liquid, the preheating water tank 20 comprises a water storage cavity 21 and an overflow pipeline 22, and the overflow pipeline 22 is arranged in the water storage cavity 21; the water outlet of the water storage chamber 21 and the water outlet of the overflow pipe 22 are connected to the washing connection pipe 60.

The liquid in the water storage cavity 21, which is higher than the water inlet of the overflow pipeline 22, can flow out through the overflow pipeline 22, and the liquid, which is lower than the water inlet of the overflow pipeline 22, can flow out through the water outlet of the water storage cavity 21 and the washing connecting pipeline 60.

According to the preheating water tank 20 of the embodiment of the present application, the water storage chamber 21 is used for storing liquid, the overflow pipe 22 is used for discharging the liquid higher than the water inlet of the overflow pipe 22, and the washing connecting pipe 60 is used for discharging or delivering the liquid in the preheating water tank 20 to other devices such as the liner 10, the water softener 70, etc. After the overflow pipeline 22 is arranged in the preheating water tank 20, the liquid in the preheating water tank 20 can be quantitatively stored, and the preheating water tank 20 has a certain preheating function, so that heat exchange with the ambient temperature can be realized, when a heat source exists around the preheating water tank 20, the liquid in the preheating water tank 20 can be raised to a temperature close to the heat source, the preheated liquid in the water storage cavity 21 can be conveyed to a washing chamber of the dish washer, namely the inner container 10 of the dish washer, the temperature difference between the liquid and the preset washing temperature is reduced by the preheating water tank 20, the liquid in the inner container 10 is easier to be heated to the preset washing temperature, the heating time is shortened, the energy consumption is reduced, and the energy saving effect is realized. The preheating water tank 20 has the advantages of quantitatively storing washing liquid, reducing energy consumption of a dish washer and realizing energy conservation. It should be noted that the preset washing temperature refers to a temperature with a good decontamination effect, and specifically, different preset washing temperatures are set according to the types of tableware and stains to be washed, which is based on actual requirements, and the preset washing temperature can be adjusted according to requirements, which is not limited herein.

It should be noted that, when more liquid needs to be stored in the preheating water tank 20, that is, when liquid higher than the water inlet of the overflow pipe 22 needs to be stored, the liquid may be reversely conveyed through the overflow pipe 22, specifically, the reverse conveying of the liquid may be realized through the cooperation of the water supply pipe 50 described below, so that more liquid may be stored in the preheating water tank 20. Alternatively, the circulation of the liquid in the overflow pipe 22 may be blocked by a valve or the like, and then the water supply is directly continued through the water supply pipe 50, so that more liquid can be stored in the preheating water tank 20.

For example, when the liquid in the preheating water tank 20 can only be stored to 2.5 liters under the limitation of the overflow pipe 22, and when the liquid is stored to 3 liters, the liquid in the preheating water tank 20 needs to be higher than the liquid level corresponding to the water inlet of the overflow pipe 22, and at this time, the upper storage limit in the preheating water tank 20 can be increased by the two modes, so that the liquid can be stored to 3 liters or more. Of course the space within the reservoir 21 is capable of storing sufficient liquid.
