32) user uses the hot water flowed out in water heater, and the waste heat of hot water diffuses in surrounding air, makes surrounding air become damp-heat air;
33) when the hot water in water heater is after water heater outlet stops water outlet certain hour t3, control device in assisted heat pump device is opened, form the circulating water flow between water heater and assisted heat pump device, heat pump is started working, the heat diffused to by hot water in environment carries out collecting, heating the current flowing through assisted heat pump device condenser through evaporimeter, and the water vapour in surrounding air is condensed into condensed water, to carry out dehumidification treatments to the air in environment;
Preferably, t3 is 15 minutes.
11., according to the arbitrary described control method of claim 7 to 10, is characterized in that: after the control water pump start/stop work of assisted heat pump device, and the bactericidal device start/stop work in air channel, carries out bacteria removing to the air-flow flowed through;
Preferably, the working method of assisted heat pump device is as follows:
1) air in environment is formed the heat exchange air-flow flowing through air channel by blower fan, and the evaporimeter in air channel and the exchanging air stream flowed through carry out heat exchange, to be absorbed heat by the coolant media flowing through evaporimeter to the waste heat recovery in surrounding air, waste heat;
2) water in the water tank of water heater is formed from water tank to water inlet pipe to condenser to outlet pipe to the circulating water flow of water tank, refrigerant after heat absorption carries out heat exchange, to carry out auxiliary heating to the water in water-heater water tank through condenser and the circulating water flow flowing through condenser.
