The working process of the invention is as follows:
in the working process of the bathroom heat recovery water heating device, bath wastewater is collected by the filter tank 10 through the filter 13 and enters the wastewater heat exchanger 8, the temperature of tap water is raised through forward flow heat exchange, then the tap water enters the heat exchanger I11 to heat refrigerant sucked by the compressor 2 in the gas-liquid separator 1, the suction temperature of the compressor 1 is raised, meanwhile, the exhaust temperature of the compressor 1 is correspondingly raised, the high-temperature refrigerant further heats water heated by the wastewater heat exchanger 8 through the shower water heat exchanger 7, the temperature is raised to the required bath hot water temperature, and the water is mixed with tap water for shower.
