Description
Technical field
The present invention relates to drying plant, specifically a kind of dryer, especially a kind of dryer sentence drying method.
Background technology
Dryer is as its name suggests a kind of device for being dried clothing, and the appearance of dryer gives people life and brings
Great convenience, makes the people can also obtain dry and comfortable clothing overcast and rainy.
In for the drying mechanism of clothesdrier or clothes washer-dryer, the device of generation heating air is used mostly
The mode of heating of air is heated by heater.Existing electrothermal dryer is typically using heater strip or heating tube as warm
Source, such product energy consumption is high, and drying time is long and security is poor.For reducing energy consumption, heat pump clothes dryer is have developed, used
Heat pump, reinforcement is recycled to heat, improves the utilization ratio of heat, reduces the consumption of electric energy.
The drying method of sentencing of current dryer mainly has following three kinds：1) clothing is directly tested by clothes humidity sensor to contain
The method that water rate is judged, clothes humidity sensor is divided into resistance-type and condenser type, the different resistance of different humidity correspondences
Or capacitance, this kind of control method needs lot of experiments to be verified, is allowed to correspondence, but, clothes humidity sensor has individual feature,
It is exactly that resistance or capacitance can drift about as use time increases, so results in test value and there is deviation with actual value, separately
Outward, can also be run into practice and judge inaccurate situation, such as load is wrapped up by big object, and big object is dry, but quilt
The load of parcel is still moist, the abnormal conditions such as load drying deficiency is also resulted under such failure conditions, to small cloth drying
When, clothing is small with the probability of sensor contacts, measurement result can be caused inaccurate, and easily erroneous judgement clothing is dry.Or
When drying the uneven clothing of jeans equal thickness, the cloth that there is detection position is dry, and the weight such as leg cuff, pocket
Folded position after original detection EP (end of program) according to not being completely dried；2) EAT and the air-out of drying are passed in and out by detecting
Temperature is judged that after EAT and the leaving air temp temperature difference reach certain setting value, then time delay is for a period of time, clothes drying process
Terminate；3) by testing the air outlet temperature and air outlet relative humidity comprehensive descision dryer termination condition of drying.
The method that load degree of drying is judged using temperature sensor is fairly simple, is in the load of standard environment normal capacity
Under, the drying time or a design temperature of the setting of operation one.Such as heater power ratings are 1600W, rated capacity is 6kg
Tumbler dryer, the cotton of standard 6kg is loaded the final moisture content of drying to 4% using standard energy consumption program, program sets
Surely 180 minutes or air outlet temperature are run and set 50 DEG C, when running between or air outlet temperature any value reach setting value
When, dryer stops heating.This method needs the species and quality of strict implement clothing, but, user is using dryer
When, it is all uncertain to be put into the species of roller undergarment, quality, initial aqueous rate, therefore judgement precision to dryer will
Ask very high, can otherwise cause clothing to dry and not do, or drying time is long, can so cause the use anticipated deviation of user.
The Chinese patent of Application No. CN201020104047.X discloses a kind of clothes drying process intelligence based on weight method
Fuzzy control device, the Intelligent fuzzy control device judges that load is dry by fuzzy algorithmic approach by continuous test load weight
Dry degree.The use scope of the Intelligent fuzzy control device is narrower, when drying works, drying be continuous rotation status or
Dwell time is very of short duration, and this increased very big difficulty to measurement weight, and measurement result there is also certain error.
The Chinese patent of Application No. CN200910210029.1 discloses a kind of heat pump clothes dryer and heat pump clothes dryer
Control method, the control method is comprised the following steps, there is provided one dries cavity, and control discharges heat by drying the gas that cavity leaves
Outside pump dryer, whether the action that judgement dries cavity meets a predetermined condition.If the running for drying cavity meets predetermined bar
Part, then control by drying gas backstreaming that cavity leaves to drying cavity.The control method be by measure the humidity of clothing and
Air intake absolute moisture content, air-out absolute moisture content and EAT, return air temperature, air intake between return air temperature etc., the control
Method processed equally exist due to use time it is permanent caused by measured deviation problem, and then influence dryer workability
Energy.
