きた。Conventional configurations and their problems Traditionally, in household electric dryers, etc., the operating time of the dryer was set by the user relying on intuition.
This will cause variations in the drying state. Improve this. For this purpose, electrodes were installed in the drying drum to measure the electrical resistance of the clothes, detect dryness of the clothes, and control the dryer N'. However, in this case, the resistance value for dryness detection is several tens of thousands.
It was set to a value of MΩ to approximately 1009, and when the electrical resistance of the clothing exceeded this value, it was only detected that the clothing was dry, and the drying rate of the clothing could only be roughly controlled. In addition, in recent years, the method of using the dryer has been to dry the clothes slightly damp, which is approximately 95% dry
As the dryer has come to be used by stopping the dryer once it has dried to a certain percentage, taking out the clothes and ironing them, more precise control has become necessary.

である。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes clothing, 2 a drying drum in which the clothes are rotated and dried with hot air, 3 an electrode provided in the drying drum 2 to detect the electrical resistance of the clothing 1 that comes into contact with it, and 4 6 is a temperature sensor that detects the temperature of the exhaust gas from the drum; 6 is a temperature sensor that detects the resistance between the electrodes of the electrode 3;
Reference numeral 7 denotes a control means for controlling the drive of the heater 8, motor 9, etc. based on the detection signals from the resistance detection device 4 and the temperature detection device 6.

。To explain the operation in the above configuration, when the clothing 1 is initially wet, the resistance value between the electrodes 3 is in a state of several Ω, but when the clothing 1 dries and the resistance value exceeds 10MΩ to 20MΩ, the resistance is detected. The device 4 detects this, sends a signal to the control means 7, stops the heater 8 and motor 9, and ends the drying. At this time, the relationship between the resistance between the electrodes 3 and the drying rate of the clothing 1 is as shown in Figure 2, so when the drying rate of the clothing 1 reaches approximately 96 cm, the air blowing operation is started for a certain period of time, and the dryer 9 stops. .

したがって、そのまま衣類１を取９出せばアイロン掛け
がすぐに出来るという効果がある。Therefore, if you take out the clothes 1 as they are, you can immediately iron them.

ることができるという効果がある。Also, after the electrode 3 detects that the drying rate of the clothing 1 is approximately 96%, the temperature sensor 6 detects the exhaust temperature from the drying drum, and has the exhaust temperature increased to a certain level or higher? When the temperature detection device 6 detects that the clothes 1 are dry, the electric blowing operation is started and stopped. By setting the temperature rise value at this time to a constant value, there is an effect that the drying rate of the clothes can be kept constant.

By setting between M'j;), it is possible to dry the clothes to a total dryness rate of about 95%, stop the dryer, take them out, and iron them. In addition, by stopping drying when the exhaust temperature rise reaches a certain value after detection with electrodes, it is possible to dry clothes at a constant drying rate, and the practical effect is There is something.
