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 and a control method, the dish washing machine comprises a water tank, a circulating pump and a sleeve heat exchange device, the sleeve heat exchange device comprises a sleeve and a drainage pipeline, the sleeve is provided with a water inlet and a water outlet, the water inlet is communicated with the water tank, and the water outlet is communicatedwith the circulating pump; and the sleeve is communicated with the water tank through the drainage pipeline. The casing pipe heat exchange device comprises a plurality of casing pipes, the different casing pipes are sequentially communicated through detachable first connecting structures to form a water flow channel, one end of the drainage pipeline is connected with the casing pipes and / or the first connecting structures, and the other end of the drainage pipeline is connected with the water tank. According to the dish washing machine, the sleeve heat exchange device can be disassembled and cleaned, washing water in the sleeve can be guided to the water tank through the drainage pipeline during drainage, the washing water in the sleeve can be conveniently drained, and the interior of thesleeve is kept clean.

Description

technical field [0001] The invention belongs to the field of dishwashers, and in particular relates to a dishwasher and a control method. 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 dishwasher...
