2. Description of the Related Art In a conventional clothes dryer, a user sets a drying operation time by a timer. However, there is a problem that the time is set too depending on the user's can, which causes excessive drying or insufficient drying. In order to improve this problem, the resistance of the cloth when the cloth comes into contact with the electrode is measured by the electrode provided in the drum and the wetness of the cloth is detected, and the resistance value of the cloth becomes a certain value or more. After completion of the dryness detection (drying detection step), a drying delay step for a fixed time is performed, or the time t of the dryness detection step is measured from the start to the end of the dryness detection, and the time T of the remaining drying delay step is determined in advance. A clothes dryer that uses a given function (for example, T = 0.2 × t) has been put into practical use.

After setting the dry course with the dry course selection switch 14,
When the start switch 13 is pressed, the motor 1 and heater 6
Is energized to start the operation. At the start of operation, the clothes inside the drum 3 are wet, so the detection resistance of the electrode 11 is small and the output signal of the dryness detection unit 18 is at the L level, but the cloth is getting dry and the preset resistance R is set. When S or more, the output signal becomes H level. The relationship between the detection resistance and the operating time is shown in FIG. That is, the sense resistor a predetermined time T 1 minute (t 2 -t 1) is continuously becomes higher than R S, the value of the time t 2 until the sensed from the start of operation, remaining dry delay time (e.g., 0.2 + t 2 ) Decide. The time until t 2 is the dryness detection process,
The time remaining t 3 -t 2 is a dry delay step. The reason for providing the drying delay step is that not all the cloths are completely dried at the end of the drying detection step. The drying delay step may be a fixed time.

If the detection resistance becomes smaller than R S during the fixed time of T 1 minute (t 2 −t 1 ), the measurement of T 1 until the fixed time is stopped and the measurement is performed again. Next, the operation when the door 7 is opened during operation to temporarily stop the operation or when cloth is added will be described. Even if the door 7 is opened and a damp cloth is added in the dryness detection step, there is no problem because the dryness is detected, but if a damp cloth is added during the drying delay step, the dryness detection is performed in this step. Since it is not performed and the process is performed for a predetermined time, the wet cloth may not be dried. As a solution to this problem, in the present invention, when the door 7 is opened and closed during operation, dry detection is performed again even during the drying delay step, and if the detection resistance is R S or more continuously for a certain period of time, Perform the drying delay process time decided before opening and closing the door. In addition, the detection resistance becomes R S
When the following occurs, the time so far is cleared, the process is returned to the dryness detection process, and control is performed so that the dryness detection process is performed from the beginning.

1. A door switch for detecting the opening and closing of a door for putting in and taking out clothes, a dry detecting section for converting a resistance value of cloth in the drum into a voltage by an electrode provided in the drum, and a dry detecting section. The resistance value of the cloth is measured at regular intervals, and if the resistance value of the cloth is equal to or higher than the predetermined resistance value for a certain period of time, it is judged that the cloth is dry, the drying detection process is terminated, and further auxiliary drying is performed for a set time. When the door is opened and closed during the drying delay step, the control means performs drying detection again for a certain period of time, and the drying is detected by the drying detection step. If it is determined that the drying delay step is continued, and if it is determined that it is not dried, control is performed to return to the drying detection step again.
