The outlet air water capacity D2 and the inlet air water capacity D1 differences of the detection of first Temperature Humidity Sensor 221 with it is default
Air humidity content △ D compare, and determine that dryer is to be in drying stage or temperature-fall period；As the outlet air water capacity D2
It is more than preset air water capacity △ D with the difference of the inlet air water capacity D1, then dryer is in drying stage, works as outlet
The difference of the air humidity content D2 and inlet air water capacity D1 is less than preset air water capacity △ D, then dryer is in drop
Thermophase；12 downstream portion of the main condenser that air passes through in the air circulation duct 21 is provided with to detect described
The temperature sensor 223 of the air themperature of 22 import of hothouse, the temperature T0 and first detected according to the temperature sensor 223
Set temperature T1 and third set temperature T3 compare and dryer residing for stage, control main condenser 12 pass to air
Heat, in addition temperature sensor 223 can also be arranged at hothouse air intlet position；Certain Temperature Humidity Sensor also may be used
To be the moisture tester for detecting clothes water in hothouse, the humidity of the hothouse can also be the water content of clothes, root
The stage residing for dryer is determined according to the water content of the indoor clothes of drying, and it is cold that the temperature sensor can be set to the master
Condenser surface, to detect the circulating air temperature Tc on main condenser surface, according to temperature sensor detection temperature Tc with set
Constant temperature degree compare and dryer residing for stage, control main condenser passes to the heat of air；Due to detection temperature position
Difference, set temperature is also different, is selected according to actual conditions.
In first embodiment of the invention, the accessory fan 16 of heat pump clothes dryer is multi gear position wind turbine, and rotating speed is adjustable, also may be used
Think the wind turbine of stepless speed regulation；Specifically, if wind turbine gear includes one grade and two grades, two grades of rotating speeds are more than one grade of rotating speed；According to
In the stage residing for temperature and dryer that temperature sensor 223 detects, select one grade or two grades；Accessory fan 16 is in one grade
When, accessory fan 16 makes 15 unit interval of auxiliary condenser heat exchange amount be equal or slightly larger than 11 input power of compressor, assists wind
When machine 16 is in two grades, when accessory fan 16 makes 15 unit interval of auxiliary condenser heat exchange amount be in one grade more than accessory fan 16
15 unit interval of auxiliary condenser heat exchange amount；When dryer is in drying stage, hothouse inlet temperature T0 reaches first and sets
When constant temperature degree T1, it is one grade that controller, which controls the unlatching of accessory fan 16 and rotating speed,；When dryer is in temperature-fall period, when dry
When dry room inlet temperature T0 reaches third set temperature T3, it is two grades that controller, which controls the unlatching of accessory fan 16 and rotating speed,；
Drying stage, the condition that control accessory fan is opened are that hothouse inlet air temperature reaches the first set temperature T1, and works as and open
Qi Hou, the condition that make accessory fan out of service are that hothouse inlet air temperature is less than the first set temperature T1；Described
Temperature-fall period, control the condensation fan open and be located at two grades condition be hothouse inlet air temperature be more than third setting
Temperature T3, it is that hothouse inlet air temperature is less than or equal to third set temperature T3 to control the condition that the condensation fan is closed；
Rotating speed when accessory fan 16 is one grade is less than rotating speed when accessory fan 16 is two grades, auxiliary when accessory fan 16 is in one grade
Help wind turbine 16 that 15 unit interval of auxiliary condenser heat exchange amount is made to be equal or slightly larger than 11 input power of the compressor, accessory fan
16 be in two grades when, accessory fan 16 make 15 unit interval of auxiliary condenser heat exchange amount be more than accessory fan 16 be in one grade
When 15 unit interval of auxiliary condenser heat exchange amount.Gear by the way that accessory fan 16 is simply arranged selects, control auxiliary condensation
Device 15 is dispersed into the heat in environment, and then controls heating amount of the main condenser 12 to circulation air, and reaching reduces hothouse 22
The effect of clothes temperature avoids high-temperature damage clothes, while can be quickly cooled down clothes after drying.Certainly, have in wind turbine
When there are more gears, condition can be made more specific；In addition wind turbine can also be the wind turbine of stepless speed regulation, in this way, specifically can be with
