Description

[Detailed description of the invention] Industrial applications The present invention relates to a clothes drying device using microwaves.

BACKGROUND ART A conventional clothes drying device of this type has the following features, as shown in FIG.
Box 1, microwave oscillator 2, heater 3, power supply
The drying apparatus is comprised of a control circuit 4, etc., and when the drying time is near, heating by microwave power is stopped and clothes and the like are heated and dried only by the heater 3. (For example, Japanese Utility Model Publication No. 55-34948) Problems to be Solved by the Invention However, in the above configuration, since the microwave is stopped near the end of drying, drying is performed only by the heater. However, this method has the problem that it takes more time than when drying is performed using microwaves.

The present invention solves such conventional problems and aims to shorten the drying time by drying clothes using only 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 metal detection sensor, and a control device for these.

Effect of the present invention With the above-described configuration, the metal detection sensor detects a metal object on the clothes while drying the clothes, stops the generation of microwaves and the operation of the rotating drum, and prevents the user from detecting the metal object on the clothes. By drying only with microwaves after removing the clothes, rapid drying is possible.

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 1
7 is a door for entering and exiting clothes.

In the above configuration, damp clothing placed in a rotating drum is usually agitated by the rotation of the drum, and is irradiated with microwaves via a waveguide 9 by a magnetron 8 . The water vapor generated from the heated clothing is sucked in through the air suction port 14 by the blower 6, and is discharged to the outside of the box body 4 through the upper opening plate 16 by air blown out from the lower opening plate 15. If the clothes have metal buttons or zippers, or if there are coins in the pockets, this will be detected by the metal detection sensor 18 shown in FIG. The metal detection sensor 18 uses, for example, a magnetic resistance element, and detects metal in clothing and changes its resistance value.

In FIG. 2, a metal detection sensor 18 detects a metal object in clothing, and transmits the signal to activate a relay 20 through a transistor 19 to close a contact point 21. That is, when some metal object is detected in clothing, the metal detection sensor 18 opens the contact 21 by the above operation, stops the operation of the motor 13 of the rotating drum 11 and the magnetron 8, and
The user is made aware of this and is encouraged to remove clothing that has metal objects on it. Once the clothing with the metal object is removed, the contacts 21 are closed and the motor 13
And magnetron 8 starts operation. Microwave irradiation can be applied from the start to the end of drying, and there is an effect that clothes can be dried quickly.

Note that 22 is a resistor volume for adjusting the sensitivity of metal object detection, 23 is a DC power supply, and 24 is a commercial power supply.

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

(1) Since it has a metal detection sensor that detects metal objects in clothes, it is possible to dry clothes using only microwaves, which has the effect of shortening drying time.

(2) For the same reason, metal objects in clothing are not damaged by irradiation with microwaves.
