Heat recovery type bathing machine

Abstract

The invention discloses a heat recovery type bathing machine, which comprises a high-temperature water box, a low-temperature water box, a compressor, a bathing table recovery box and an evaporation box, wherein clean water flowing into a heat exchange coil pipe arranged in the bathing table recovery box carries out heat exchange with hot sewage outside the pipe, the hot sewage subjected to the heat exchange enters the evaporation box, the clean water subjected to the heat exchange is mixed with unheated clean water through a water mixing valve after sequentially flowing through a medium-temperature water box and the high-temperature water box and is then sprayed out from a spray head, gaseous refrigerants discharged out from the compressor are subjected to heat exchange with clean water outside the pipes after sequentially passing through a third heat exchange coil pipe arranged in the high-temperature water box and a fourth heat exchange coil pipe arranged in the medium-temperature water box, the gaseous refrigerants subjected to heat exchange become a liquid state through condensation heat release, liquid-state refrigerants enter a second coil pipe arranged in the evaporation box to be subjected to heat exchange with the hot sewage outside the pipe, the liquid-state refrigerants subjected to heat exchange become a gaseous state, and the gaseous refrigerants flow into the compressor and are then discharged out after being compressed. The heat recovery type bathing machine has the advantages that the reutilization of waste heat of the hot sewage is realized, the hot water bathing requirement is met, and the utilization efficiency of energy sources is greatly improved.

Description

technical field [0001] The invention relates to the field of hot water machines, more specifically, to a heat recovery type bathing machine. Background technique [0002] At present, with the improvement of people's living standards, various water heaters are widely used in households and various commercial occasions, especially sauna bath centers, hotels, schools, hospitals and other industries have a great demand for hot water. The safety of traditional gas water heaters has been questioned, electric water heaters consume a lot of energy, and solar water heaters are not effective in winter. In recent years, air-energy heat pump water heaters have been vigorously promoted and applied, but there is also insufficient low-temperature heating capacity, and electric heating must be supplemented to meet the demand for hot water in winter, and the energy consumption is also relatively large. At the same time, after the hot water used by people is turned into sewage, there is ofte...
