Description

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

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, some of the metals included in the clothing become extremely hot in a short period of time when drying using microwaves is started. There are some things. In this case, there was also the disadvantage that the fabric around the metal was damaged.

The present invention solves this conventional problem by irradiating clothing with metals with reduced microwaves to prevent abnormal heating of the metals and damage to the clothing. The purpose is to

Means for Solving the Problems In order to solve the above-mentioned problems, the clothes drying device of the present invention is provided with a metal auxiliary drying box for reducing the intensity of microwaves in a rotating drum that accommodates clothes. It is something that

According to the above-described structure, the present invention reduces the intensity of microwaves applied to metals by storing them in an auxiliary drying box provided in advance in a rotating drum when drying clothes containing metals. .

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

In FIGS. 1 and 2, 5 is a box of a clothes drying device, and has a blower 6 at the bottom, a transformer 7 as a microwave generator, a magnetron 8, a waveguide 9, a control device 10, etc. Reference numeral 11 denotes a rotating drum made of plastic in which clothing is stored, and is driven by a motor 13 via a shaft 12.

Reference numeral 14 denotes an auxiliary drying box fixed to the side wall of the rotating drum 11, which has an opening 15 around the periphery and a removable lid for putting in and taking out clothes containing metal objects. 16 is an air intake port, 17
18 is a lower opening plate, 18 is an upper opening plate, and 19 is a door for putting in and taking out clothes.

In the above configuration, damp clothing placed in the rotating drum 11 is normally irradiated with microwaves by the magnetron 8 through the waveguide 9 while the rotating drum 11 is being rotated. The water vapor generated from the heated clothing is
The air sucked in from the air suction port 16 by the blower 6 and blown out from the lower opening plate 17 causes the upper opening plate 1 to
8 to the outside of the box body 5. Clothes containing metal items are stored in the auxiliary drying box 14 when drying starts. Clothes stored in the auxiliary drying box 14 are only irradiated with radio waves that enter through the opening 15, and the amount of microwaves is greatly reduced, so metals will not be heated abnormally.

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

Clothes containing metals are stored in an auxiliary drying box that greatly reduces the amount of microwave radiation, thereby preventing clothing from being burnt out due to abnormal heating of the metals.
