Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drying control device in which the drying rate at the end of drying of clothes can be varied by setting from the outside.

In conventional rotary drum type clothes dryers, for example, only when completely dry, that is, the drying rate is 102 to 104.
The completion of drying was notified only when the drying temperature reached %. If the clothes are taken out after they are completely dry, the clothes will naturally not be damp and cannot be ironed in that state. When ironing, it is necessary to separately spray water in a mist, which makes the ironing work troublesome.

The present invention solves the above-mentioned conventional inconveniences, and uses simple means to keep clothes slightly damp (with a drying rate of 90 to 100).
%), the user can perform a selection operation to notify the completion of drying. This reliably meets the request to iron the clothes after drying, shortens the operating time of the dryer, and eliminates the wasteful work of moistening the clothes again during ironing.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the basic configuration shown in Fig. 1, 1 is a sensor, for example, a pair of electrodes installed in a rotating drum for storing clothes.When clothes touch, a current flows between the electrodes through the clothes. A voltage 3,- is generated, and this voltage output is input to the comparison means 2. The comparison means 2 is composed of, for example, a resistor and a comparator, and compares the output of the sensor 1 with a reference voltage to determine whether the instantaneous resistance value of the cloth is sufficiently large, and inputs the result to the first timer means 3. . The first time limit means 3 is composed of, for example, an OR integrator, a resistor, and a comparator, and is set and reset by the output of the comparison means 2, and if the output of the comparison means 2 remains for a certain period of time or more, it is determined that the data is true. The output of the first timer 3 is input to the second timer 4, thereby setting the second timer 4.

will be reset. The second timer 4 is composed of, for example, an OR integrator, a resistor, and a comparator, and detects the dry state based on the time ratio of the output of the first timer 3 that determines that the resistance value of the clothing is large. and sends a signal to the notification means 6. The notification means 5 includes, for example, a buzzer.

Reference numeral 6 denotes a time setting means, which includes, for example, a resistor and a switch for switching the resistance value. By switching the resistance value,
The charging time constant of the OR integrator of the second time limit means 4 is switched. As a result, the ratio of the time period for charging, which is the condition for sending a signal to the notification means 5, that is determined to be dry, and the time period for discharging, that is, the time period, that is determined to be undried, is changed, and the notification means 6. It is possible to switch the drying rate during operation.

FIG. 2 shows a specific configuration, in which 7 is a pair of electrodes, M anti-8.
The sensor 1 is constituted by the Zener diode 9. Comparison means 2 which receives the output of sensor 1 as input is resistor 10
．． 11 and comparator 12. First time limit means 3
is the resistance 13. It consists of an OR integrator consisting of an electrolytic capacitor 14, a resistor 16° 16.17 and a comparator 18. The second timer means 4 comprises a resistor 19, an OR integrator consisting of an electrolytic capacitor 2°, resistors 21, 22, 23, 24 and a comparator 26, and further includes resistors 21, 22 of different resistance values connected in parallel. Either one of the above OR
A switch 26 is provided which is operated by the user to set the charging time constant of the integrator. That is, the second time limit means 4 includes time limit setting means consisting of a switch 26 and resistors 21 and 22. The notification means 6 is a buzzer 27.

As is clear from the above embodiments, according to the present invention, the drying rate of the cloth at the end of drying can be changed by the time setting operation in the second timer, and the wet state of the cloth suitable for ironing can be ensured. , it is possible to simplify the ironing work.
