Heat pump type dish washing machine

Abstract

The invention discloses a heat pump type dish washing machine. The heat pump type dish washing machine comprises a heat pump system and a softening device used for softening washing water; the heat pump system comprises a condenser, the softening device comprises a soft water accommodating cavity for accommodating the washing water, the condenser is provided with an accommodating cavity used for storing the soft water accommodating cavity, and the soft water accommodating cavity is placed in the accommodating cavity. The condenser of the heat pump type dish washing machine is designed to be in a form matched with the softening device, thus the mounting space of the dish washing machine is fully utilized, a fixing device required by mounting the softening device is omitted, and replacing and maintenance of the softening device are more convenient. The condenser of the heat pump type dish washing machine is composed of a wound heat-exchanging sleeve which rises spirally, the condenser is overall arranged in a base of the dish washing machine, the softening device is mounted at a hollow part of the spiral heat-exchanging sleeve, the machining and mounting processes are simple, the overall appearance size of the dish washing machine is decreased, and the heat exchanging efficiency of the condenser is high.

Description

technical field [0001] The invention belongs to the field of kitchen equipment, and in particular relates to a heat pump 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, a variety of small dishwashers are on the market and are gradually entering ordinary families. [0003] Existing dishwashers all 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...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned patent has the following problems: the invention transfers the high heating capacity of the condenser to the inner container, and heats the washing water through the inner container, which not only has low heat transfer efficiency of the washing water, but also provides high efficiency for the inner container of the dishwasher. Insulation material, manufacturing cost and processing technology requirements are very high

For the softening function of the softener, there must be a brine cavity for containing brine and / or a resin cavity for containing resin. These cavities must occupy a certain space, which is not conducive to reducing the overall size of the dishwasher and limits the dishwasher promotion and installation
