Generally, the temperature of hot water bath is about 45 ℃, heat loss is about 3-5 ℃ after the hot water bath flows through a human body for utilization, and bath wastewater containing heat energy of 40 ℃ directly flows away and is wasted. The waste heat recovery of the bath wastewater refers to the recovery and utilization of heat energy of the waste hot water after bathing by using a wastewater energy hot water machine, can realize more than 90 percent of heat energy recovery, and plays an important role in reducing fuel, heating cost and environmental pollution. At present, some waste water recovery devices appear on the market, such as: the centralized large-scale sewage source heat pump takes sewage as a cold and heat source of an air conditioning system to realize the purposes of refrigeration and heating. The sewage source heat pump has higher requirements on the sewage water quantity, the water temperature (10-25 ℃) and the water quality, and the system is complex, has large operation and maintenance workload and high investment, is only suitable for commercial occasions and is not suitable for families.
Chinese patent CN102287944A discloses a device for recovering heat energy from waste water (or industrial waste water pool) in a bathing pool, which is composed of a heat exchanger, a water replenishing and heat extracting system, a water source heat pump and a hot water tank in the pool. Running water enters the heat exchanger through the water supplementing switch, enters the hot water tank after exchanging heat with hot water in an original wastewater pool (original bath), and is automatically turned off when the temperature of the water in the wastewater pool is reduced to a certain temperature (for example, 20 ℃, and the water amount in the hot water tank reaches the water amount in the original wastewater pool); the system starts the water source heat pump system to continuously extract the heat energy in the wastewater pool, so that the water temperature in the wastewater pool is continuously reduced, the water temperature in the hot water tank is continuously increased, and when the water temperature in the wastewater pool is reduced to a set temperature (such as 10 ℃) and the water temperature in the hot water tank is increased to a set temperature (such as 50 ℃), the water source heat pump system is automatically closed, so that the whole process of extracting the heat energy is completed. Then the waste water in the waste water pool is discharged, the waste water pool and a heat exchanger in the pool are cleaned manually, a hot water switch is turned on, and all hot water in a hot water tank is discharged into the pool for a new round of bathing. The structure does not change the structure of the large-scale water source heat pump, and can only be applied to the large-scale hot water pool; the system has complex structure composition, needs to construct a large-scale hot water tank, increase equipment such as a water pump and the like, also needs to specially construct a machine room and has large investment.
