Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a clothes drying device using microwaves.

2. Description of the Related Art A conventional clothes drying device using microwaves includes a heating device 20 using microwaves and a blower 2, as shown in FIG.
1, a heater 22, and a control device 23 for these. (For example, Japanese Utility Model Publication No. 55-34948) Problems to be Solved by the Invention However, with the above configuration, when the drum on which clothes are placed rotates, there is no problem with the generation of microwaves and the rotation mechanism of the drum. Because of the lack of controllability, there was a major drawback in that metal buttons came into contact with each other inside the drum, causing sparks that could damage clothing. Additionally, if the microwave and heater were operated at the same time, the power consumption would exceed the power capacity for household use. The present invention solves such conventional problems, and aims to effectively control the rotation of microwaves, heaters, and drums, thereby preventing the generation of sparks and the temporary increase in power consumption. shall be.

Means for Solving the Problems In order to solve the above problems, the clothes drying device of the present invention has the following features:
The lower part of the main body contains a blower, a heater, a microwave generator, etc., and the upper part contains a box body with a drum inside and whose bottom and top surfaces are formed by opening plates, a motor for rotating the drum, and a microwave generator. The apparatus is equipped with a configuration consisting of a control device that alternately operates the motor and the heater.

Function: With the above-described configuration, the present invention stops the driving of the motor and stops the rotation of the drum during heating by microwaves, thereby preventing the metal buttons from coming into contact with each other. Thereafter, the motor is started to rotate, the drum starts to rotate and the heater starts to operate, and at the same time, the microwave oscillation is stopped. By repeating these operations alternately, drying of clothes is promoted without sparks being generated and without temporarily increasing power consumption.

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

In FIG. 1, reference numeral 1 denotes a main body, which has an air suction port 2, a blower 3, a waveguide 4, a microwave generator such as a magnetron 5, a transformer 6, etc., and a heater 7 at its lower part. The upper part of the main body 1 has a plastic drum 8 with a large aperture ratio inside, and the bottom and top surfaces are aperture plates 9 and 10 to form a box.

11 is a motor that rotates the drum 8 via a shaft 12, and 13 is a door for loading and unloading clothes. FIG. 2 is a control circuit diagram for controlling the motor 11, the microwave generator, and the heater 7. As shown in FIG. Reference numeral 13 denotes a power source, which drives a relay 15 at regular intervals using a timer 14. That is, when the relay 15 is driven, only the contact 16 is closed, and the magnetron 5 and the blower 3 are operated. When relay 15 stops driving after a certain period of time, contact 16
is opened, and contacts 17 and 18 are closed to operate the motor 11, heater 7, and blower 3.

19 is a commercial power supply.

In the above configuration, the damp clothes placed in the drum 8 are heated by the magnetron 5 and through the waveguide 4, and the water vapor generated from the clothes is discharged to the outside of the main body through the opening plate 1o on the top surface. be done. Since the drum 8 is stopped at this time, the metal buttons of clothing inside the drum will not touch each other and cause sparks. When the magnetron stops operating after a certain period of time, the drum rotates and the heater starts operating to accelerate drying.

The above operations are performed alternately to dry the clothes. In the above operation, the magnetron and heater are not operated at the same time, so power consumption does not temporarily increase.

Effects of the Invention As described above, the clothes drying apparatus of the present invention provides the following effects.

(1) Since the drum does not rotate when microwaves are generated, metal buttons on clothing do not touch each other and cause sparks.

(2) Since the magnetron and heater are operated alternately, power consumption does not increase temporarily.
