The invention provides a dish-washing machine waste heat recovery device, a waste heat recovery method and a dish-washing machine. The dish-washing machine waste heat recovery device comprises a water tank, and a spiral pipe heat exchanger is arranged in the water tank; the water tank is respectively provided with a water tank waste water steam inlet, a water tank waste water steam outlet, a water tank cold water inlet and a water tank hot water outlet, wherein the water tank waste water steam inlet is communicated with a dish-washing machine waste water outlet, and the water tank waste water steam outlet is communicated with a kitchen sewer pipeline; and the water tank cold water inlet is communicated with a tap water pipeline. According to the dish-washing machine waste heat recovery device, the dish-washing machine is internally provided with the water tank, the spiral pipe heat exchanger is arranged in the water tank, and waste water and steam are discharged from the dish-washing machine through an internal spiral pipe, so that hot water in the water tank is heated; and the spiral pipe for heat exchange can condense the steam and hot air, and the influence on the temperature and humidity of a kitchen is reduced.
Description
technical field [0001] The invention relates to a dishwasher waste heat recovery device, a waste heat recovery method and a dishwasher. Background technique [0002] At present, dishwashers generally use electric heating and high-temperature hot water to wash dishes. After washing, the waste water (generally 80-90°C) will be drained directly, which wastes a lot of heat. The newly imported cold water needs to be heated for a long time to wash dishes. The waste water after washing dishes has to be drained because it is dirty, but in fact the temperature is still very high, which contains a lot of high-quality heat. Many people choose electric heaters with higher power to improve the efficiency of dishwashing and shorten the time. Not only the energy consumption is high in the later use, but also the initial investment is increased. [0003] The patent with the publication number CN210931259U discloses a method for recovering waste hot water and waste steam from a dishwasher, ...
