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 2, a circuit 4, etc., and when the end of drying is near, heating by microwave power is stopped and the heater 3
Clothes, etc., were heated and dried using a chisel.

(For example, Japanese Utility Model Publication No. 55-34948) Problems to be Solved by the Invention However, with the above-described configuration, some of the metals included in the clothes may dry for a short time when drying with microwaves is started. Some things can get quite hot. In this case, there was a drawback that the fabric around the metal was damaged.

The present invention solves this conventional problem by detecting metals that have become hot while drying clothes with microwaves,
The purpose is to prevent damage to clothing, etc.

Means for Solving the Problems In order to solve the above problems, the clothes drying device of the present invention has the following features:
There is a microwave generator that dries the clothes stored in the rotating drum, a temperature sensor that detects the temperature of the clothes, and a temperature sensor that detects when the metal parts of the clothes are at a high temperature and generates microwaves. The system is equipped with a control device for generating and stopping the rotating drum.

Effect of the present invention With the above-described configuration, when metals attached to clothes are heated to an abnormally high temperature while drying clothes using microwaves, a temperature detection sensor detects this and causes the generation and rotation of microwaves. Stop drum operation to prevent damage to clothing.

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 via the waveguide 9 by the magnetron 8 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 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. During microwave irradiation during the drying process as described above, if the electric field concentrates on metal buttons or zippers on clothing and the temperature reaches a high temperature, use the infrared temperature detection sensor shown in Figure 2. 18 detects this fact. In FIG. 2, a temperature detection sensor 18 detects an abnormally high temperature that occurs during drying, and transmits the signal to a relay 20 via a transistor 19, which opens a contact 21 to connect a magnetron 8 and a rotating drum motor 13. stop operating. Furthermore, at this time, a buzzer (not shown) can be used to notify the user that the operation has stopped, prompting the user to take out clothing with metal objects that have reached a high temperature. 18 resistance volume for sensitivity adjustment,
28 is a DC power supply and 524 is a commercial power supply.

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

Equipped with a temperature sensor that detects abnormally high temperatures of metal objects placed on clothes being dried, and if abnormally high temperatures occur, the magnetron and rotating drum will stop operating, thereby preventing damage to clothes. effective.
