Problems solved by technology

The disadvantages of this type of heat exchanger used in dishwashers are that it takes up a large area and the space inside the spiral cannot be used effectively. Second, once the pollutants in the tableware enter the casing, they are not easy to discharge.
Since the entire casing heat exchanger is bent from a long tube, it cannot be handled by manual maintenance in time.

Abstract

The invention discloses a dish washing machine. A water tank, a circulating pump and a heat pump system are arranged in the dish washing machine, the heat pump system comprises an evaporator, a compressor and a sleeve heat exchange device, the sleeve heat exchange device comprises at least one sleeve, the sleeve is provided with a water inlet and a water outlet, the water inlet is communicated with the water outlet of the water tank. The water outlet is communicated with the water inlet of the circulating pump, and the position height of the axis of the sleeve is not lower than that of the water outlet of the water tank and not higher than that of the water inlet of the circulating pump; the evaporator, the compressor and the sleeve heat exchange device are arranged around the water tank and located on the different side portions of the water tank respectively. The sleeve heat exchange device can be disassembled and cleaned, washing water in the sleeve can automatically flow back to the water tank by arranging the installation positions of the sleeve, the water tank and the circulating pump, the washing water in the sleeve can be conveniently discharged, meanwhile, all components of the heat pump system are reasonably arranged, space is saved, And more effective washing space can be provided.

Description

technical field [0001] The invention belongs to the field of dishwashers, and in particular relates to a dishwasher. Background technique [0002] Dishwashers are equipment used to automatically clean tableware such as bowls, chopsticks, plates, plates, knives, forks, etc. According to the structure, they can be divided into two categories: box type and conveyor type. It reduces labor intensity, improves work efficiency, and improves cleanliness and sanitation for the cooks in restaurants, hotels, and canteens of government agencies. Now, various small dishwashers have gradually entered ordinary families. [0003] At present, some dishwashers use heating tubes for the dishwasher. The heating tubes are built into the water tank at the bottom of the liner. When washing, the heating tubes are used to heat while the circulating pump circulates water to wash the dishes. But this method consumes a lot of power and the drying is not complete. Some dishwashers use a heat pump sys...
