Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a clothes drying device using microwaves.
The present invention relates to a clothes drying device that prevents sparks from occurring on metal buttons and fasteners attached to clothes.

Prior Art Conventional devices of this type prevent the concentration of electric fields on high-loss objects such as metal buttons and zippers.
As shown in FIG. 3, a box 1, a microwave oscillator 2,
It consists of a heater 3, a power supply/control circuit 4, etc., and when it approaches the end of drying, heating by microwave power is stopped and clothes, etc. are heated and dried only by the heater 3. . (For example, Jikko 55-34
(No. 948 Publication) Problems to be Solved by the Invention However, with the above configuration, if metal objects attached to clothing continue to come into contact with each other while irradiating clothing with microwaves, sparks may be generated continuously. This has the problem of damaging metal buttons, zippers, or the clothing itself.

The present invention solves such conventional problems and aims to prevent damage to clothing by preventing continuous generation of sparks while drying clothing with microwaves.

Means for Solving the Problems In order to solve the above problems, the clothes drying device of the present invention has the following features:
It is equipped with a configuration consisting of a microwave generator, a rotating drum, a spark detection sensor, and a control device for these.

According to the above-described structure, the present invention detects when sparks are generated while drying clothes, and controls the generation of microwaves and the operation of the rotating drum to prevent continuous sparks from occurring. prevent the occurrence of

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIG. 1, reference numeral 5 denotes a box of a clothes drying device, and its lower part includes a blower 6, a transformer 7 as a microwave generator, a magnetron 8, a waveguide 9, a control device 10, and the like. 11 is a plastic rotating drum in which clothes are stored; shaft 12
It is driven by a motor 13 via. 14 is an air suction port, 15 is a lower opening plate, 16 is an upper opening plate, and 17
is the door for entering and exiting clothing.

In the above configuration, damp clothing placed in the rotating drum 11 is normally irradiated with microwaves by the magnetron 8 via the waveguide 9 without rotating the rotating drum 11 . The water vapor generated from the heated clothing is
The air sucked in from the air suction port 14 by the blower 6 and blown out from the lower opening plate 15 causes the upper opening plate 1 to
6 to the outside of the box body 5. If a spark is generated when a metal button or zipper comes into contact with clothing during irradiation with microwaves during the drying process as described above, the spark detection sensor 18 shown in Figure 2 will detect the spark. is detected. In FIG. 2, the spark detection sensor 18
detects the sparks generated during drying, and sends the signal to the transistor 19 to activate the relay 20 and the first timer 21.
The contact 22 of the second timer 23 is opened for a certain period of time, and the contact 24 of the second timer 23 is simultaneously opened and closed. This causes the magnetron 8 to stop operating for a certain period of time.

During this time, the motor 13 starts operating and the rotating drum 11 is driven, so the clothes inside the rotating drum 11 are agitated.
Change the position of the clothing to remove contact between the metal parts in the clothing.

If the first timer 21 closes the contact 22 after a certain period of time, and the second timer 23 opens the contact 22,
The magnetron 8 starts operating again, and the rotating drum remains stationary to dry the clothes. Therefore, even if the clothes are irradiated with microwaves again, no sparks will be generated.

Note that 25 is a resistor volume for adjusting the sensitivity of the spark detection sensor 18, 26 is a DC power supply, and 27 is a commercial power supply.

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

It has a spark detection sensor that detects sparks during drying, and if sparks occur, the magnetron stops operating for a certain period of time, and only the rotating drum is operated, so metal-to-metal contact is broken and sparks do not occur. It has the effect of preventing damage to clothing.
