問題を有していた。Conventional structure and its problems Traditionally, in household electric dryers, etc., the operating time of the dryer has been set by the user relying on intuition, but this can cause variations in the drying state. becomes. In order to improve this problem, electrodes were installed inside the drying drum to measure the electrical resistance of the clothes, detect dryness of the clothes, and control the dryer. However, the detection of electrical resistance using electrodes has a problem in that complete dryness cannot be detected and the clothes end up in an undried state. It is also conceivable to detect a certain period of time after the dryness detection by the electrodes is completed, but in this case, there is a problem of overdrying the clothes.

送風運転を行つた後、運転を停止する。 To explain the operation in the above configuration, when the clothing 1 is first wet, the resistance value between the electrodes 3 is several kilohms.
However, when clothing 1 dries, the resistance value becomes 10MΩ.
When it exceeds 20MΩ and the drying rate reaches about 95%,
The dryness detection signal from the resistance detection device 4 is controlled by the control means 7.
send to Since the relationship between the resistance between the electrodes 3 and the drying rate of the clothing 1 is as shown in FIG. 2, the resistance detection device 4 outputs a dryness detection signal when the drying ratio of the clothing 1 reaches approximately 95%. After inputting the dryness detection signal from the resistance detection device 4, the control means 7 controls the heater 8 to be energized if the temperature sensor 5 detects that the temperature of the exhaust gas from the drying drum has risen above a certain temperature using the temperature detection device 6. After stopping and blowing air for a certain period of time, the operation is stopped.

態に仕上げることができる。Effects of the Invention As is clear from the above embodiments, the clothes dryer control device of the present invention detects the electrical resistance between the electrodes using a resistance detection device, and when the resistance detection device finishes drying detection, the clothes dryer control device detects the electrical resistance between the electrodes. Since the heater continues to be energized until the exhaust gas temperature rises by a certain level, the resistance detection device detects that the air is not dry, but if the exhaust temperature rises by a certain level, it can be finished in a certain dry state.
