Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer controller for drying clothes contained in a rotary drum.

2. Description of the Related Art Conventionally, in this type of clothes dryer, the rotating drum is always rotated at a constant speed regardless of the amount of cloth, and the number of rotations of the rotating drum is set from the outside. They did not have a means to decide.

Problems to be Solved by the Invention However, in such a conventional configuration, the number of rotations of the rotary drum 2 cannot be changed according to the amount of cloth,
The number of rotations is set so that the cloth volume in the rotary drum 2 is optimum when the cloth volume is standard. Therefore, as shown in FIG. 2, since the small-capacity cloth 4 is lightweight, it can rotate while being fixedly attached to a part of the rotary drum 2, and the side contacting the rotary drum 2 easily dries, Other parts were difficult to dry, and the drying time was longer than necessary. When the amount of cloth is large, as shown in FIG.
Has a large weight, and the movement of the cloth 4 is small. Therefore, in order to improve the cloth rotation, it is necessary to increase the number of rotations of the rotary drum 2 to increase the movement of the cloth 4, but the constant rotation hinders the movement, which is difficult to realize.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a clothes dryer control device, comprising a drive device for driving and controlling a drum motor of a rotary drum, wherein the drive device is connected to the drum motor. It is configured to repeat energization for a certain period of time and stop energization for a certain period of time.

Action With the above configuration, the rotation speed of the rotary drum changes according to the amount of cloth. That is, when the amount of cloth is large, the number of rotations is high, so that the cloth rotation can be improved. On the other hand, when the amount of cloth is small, the number of rotations is low, so that the cloth is not fixed to the rotating drum at all times and is short Drying unevenness can be eliminated by the drying time.

Examples Hereinafter, examples of the present invention will be described with reference to the drawings.

In the figure, a rotary drum 2 is arranged in a clothes dryer main body 1. The rotary drum 2 is provided with a protrusion 3 that protrudes inward so that the cloth 4 can be easily hooked, and the cloth 4 can be apex (true) in accordance with the rotation direction a of the rotary drum 2. It is easy to move to the upper part).

Further, as shown in FIG. 1, the rotation of the rotary drum 2 is controlled so that the drive device 5 repeatedly energizes the drum motor for a certain period of time (I) and suspends energization for a certain period of time (II). Thus, the inertial rotation speed before the drum motor is stopped changes according to the cloth amount.

In the above configuration, when the amount of cloth is small, the amount of cloth is light, so the inertial force acting on the rotary drum 2 is weak, and
Since the rest time is provided, the inertial rotation speed at the time of rest becomes low, and the force of the cloth 4 dropping from the vicinity of the apex of the rotating drum 2 is larger than that of the cloth 4 sticking to the rotating drum 2.
In the rest time, the cloth 4 does not stick and drops. And
When the cloth 4 is dropped and then energized again, there is a very high possibility that a cloth surface different from the portion adhered to the surface of the rotary drum 2 before the drop adheres to the rotary drum 2. Will be dried. Then, by repeating the energization / pause of the rotary drum 2 as described above, the cloth can be uniformly dried in a short drying time.

On the other hand, when the amount of cloth is large, the amount of cloth becomes the weight,
The inertial force acting on the rotary drum 2 becomes strong, and the inertial rotation speed at the time of rest becomes high even during the rest time. Therefore, the self-gravitational force of the cloth 4 drops and the force attached to the rotary drum 2 becomes larger than in the conventional case, and the cloth rotation is improved. Then, since the energization is started again, the rotation speed of the rotary drum 2 becomes higher.
By repeating this, the cloth 4 is circulated, its movement can be increased, and the cloth can be dried uniformly in a short drying time.

EFFECTS OF THE INVENTION As is apparent from the above description, according to the present invention, a drive device for driving and controlling a drum motor of a rotary drum is provided,
The drive unit energizes the drum motor for a certain period of time and then suspends energization for a certain period of time to naturally set an appropriate number of rotations according to the amount of fabric, and to uniformly coat the fabric in a short drying time. Can be dried. Further, it is possible to achieve the object with a simple configuration without requiring a means for determining the amount of cloth.
