本発明はドラムを回転させて衣類を撹拌させな
がら熱風を加える衣類乾燥機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clothes dryer that rotates a drum to agitate clothes while applying hot air to the clothes.
従来の乾燥機は、運転の開始から終了までドラ
ムが一方向に回転し続けていたので、布がねじれ
てしわができたり、少量の布を乾燥させる場合に
は、布がだんご状になつて、その内部に熱風が通
らず、乾燥時間を長くしてもだんご状の内部は乾
燥しないという欠点があつた。 In conventional dryers, the drum continues to rotate in one direction from the start to the end of operation, which can cause the fabric to twist and wrinkle, or when drying a small amount of fabric, cause the fabric to become lumpy. However, there was a drawback that hot air could not pass through the inside of the dryer, and the dumpling-shaped inside did not dry even if the drying time was extended.
本発明は、上記従来の問題を解決するもので、
以下、詳細にその一実施例につき説明する。 The present invention solves the above conventional problems,
Hereinafter, one embodiment will be described in detail.

The timer is composed of a cam switch 3 and a timer motor 4, and is designed to close the cam switch 3 for a set time. 5 is a heater as a heat source for heating drying air; 6 is an induction motor that rotates a drum and a blower fan (none of which is shown) forming a blower mechanism that sends drying air into the drum; It's a capacitor. Induction motor 6 operates when relay contact S 1 closes and when relay contact S 2 closes.
When closed, the direction of rotation is reversed.

り返す。 8 is a timing means, which closes relay contact S 1 for several minutes, then opens both relay contacts S 1 and S 2 for several seconds, closes relay contact S 2 for several tens of seconds, and then closes both relay contacts for several seconds. After contacts S 1 and S 2 open, relay contact S 1 is closed again for several minutes, and the cycle is repeated.

て出力Ｂを出す。 Next, details of the time limit means 8 will be explained. 9 is a power transformer, 10 is a diode, and 11 is an electrolytic capacitor, which supplies DC power to the following circuits.
12 to 21 indicate circuit elements for multivibrator configuration, 12, 15, 16, 18, 20 are resistors, 13, 19 are transistors, 14, 17, 2
1 is a capacitor, and this multivibrator determines the duty of inversion. resistance 2
0, capacitor 21 constitutes an integrating circuit, and input A
Output B is output by taking the rise and fall of the voltage slowly.

２９，３０は保護ダイオードである。 22, 23, 24 are voltage dividing resistors, 25,
26 is a comparator, and the voltage outputs C and D divided by the resistors 22, 23, and 24, C is higher than D. Reference numerals 27 and 28 are relays for controlling relay contacts S 1 and S 2 , which constitute the main body of the control section in the present invention.
29 and 30 are protection diodes.

る。 Here, when the - input B of the comparator 25 becomes higher than the + input C, the relay 27 is activated, the relay contact S1 is closed, and the induction motor 6 rotates normally. Voltage B
When is between C and D, both relays 27 and 28 are off and relay contacts S 1 and S 2 are open. Voltage B
When the voltage drops further below D, the relay 28 is activated, the relay contact S2 is closed, and the induction motor 6 is reversed.

る。 As described above, according to the present invention, by occasionally reversing the rotation of the drum, the twisting of the cloth is prevented and wrinkles are prevented, and even when a small amount of cloth is dried, it does not become lumpy. The entire cloth can be dried uniformly and in a short time.
