Description
Technical field
The invention belongs to clothing process field, specifically, is related to a kind of cloth drying control method, especially a kind of heat
The control method of pump clothes drying device.
Background technology
Following air circulation duct is provided with existing heat-pump-type clothes drying device：By cold in heat pump circulating system
The heating air that condenser carried out heating is admitted to the humid air quilt for having captured moisture in the hothouse equipped with clothing from clothing
Send back at evaporator and dehumidified, the air after dehumidifying is heated by condenser again, and is sent into hothouse.
The Chinese patent of Application No. 200610153406.9 disclose one kind can make generation hothouse and heat pump it
Between the heat pump of drying air that circulates realize the clothes drying device of stable operation.Wherein, carried out by the heater in heat pump
The air of heating is sent into as in the steel ladle of hothouse, and heat is returned to after the air through filter unit of steel ladle discharge
Pump, by delivering to heater again after heat dump dehumidifying, form air circulation duct.Lint filter is provided with filter unit,
And provided with the pipeline being connected with air outlet and air induction port.
The Chinese patent of Application No. 200410097855.7 discloses a kind of clothes drying device, including：Heat pump assembly；
Drying air is guided into the heat dump to heat pump assembly, radiator and the air channel of drying room equipped with clothing；Into the air channel
It is sent into the air blower of drying air；And control device.In drying operating process, compressor and air blower are operated；When dry
When clothing operation is interrupted, control device makes the time as defined in compressor stopping.
The above-mentioned clothes-drying device using heat pump drying mode, it is higher in environment temperature, such as under 35~40 DEG C of environment, drying
Incipient stage, the air themperature being blown into laundry/drying cylinder rapidly rise to more than 60 DEG C, are blown out out of laundry/drying cylinder
Air themperature, humidity also rise rapidly.In this case, the refrigerant saturation pressure in evaporator is higher, compressor assembly
Load is big, quickly reaches the critical operating pressure of compressor.
In the drying system of heat pump clothes-drying device, the pressure of compressor assembly tolerance is corresponded between 60~70 DEG C for refrigerant
Saturation pressure corresponding to temperature, after the drying the phase, with the rise of temperature, the condensation temperature of compressor can be close to the limit of maximum pressure
Value.Existing drum-type heat pump clothes dryer, is designed with auxiliary condenser and accessory fan, so that phase or in high temperature ring after the drying
Accessory fan is acted in border, and compressor load is adjusted.
The control of cooling fan is usually that the busy hour for reaching system permission in load is opened, less than peak load
When shut down, compressor is out of service to ensure compressor reliability more than busy hour.Judging the standard of load is
The height of detecting system temperature.But at a temperature of varying environment, detect that system temperature is deposited with actual compressor Inside coil temperature
In difference, compressor existing defects if the start-stop temperature control fixed according to system, while reducing drying efficiency, can also subtract
The service life of few compressor.Therefore, it is necessary to determine compressor actual temperature according to the system temperature of environment temperature and detection, and
Compressor load standard is judged according to actual temperature.
If additionally setting environment temperature sensor to increase cost, and then it is pressurized merely with the detection of system temperature sensor
The interference of contracting machine operation, such as compressor have carried out an arid cycle, judge that the environment temperature detected can be made with system temperature
Spend higher.
In view of this it is special to propose the present invention.
