Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for a clothes dryer that uses high frequency waves.

Conventional clothes dryers are generally drum-type dryers or hanging-type dryers that use electric heaters, but drum-type dryers tend to cause wrinkles in clothes and uneven drying. In addition, a hanging type dryer has a problem in that it takes a long time to dry. Therefore, in order to solve these problems, a hanging type dryer using high frequency was developed, but this hanging type dryer has a large clothes input port.
For example, when a child enters the drying room and closes the door, high frequency waves are generated, which is extremely dangerous.

The present invention eliminates the above-mentioned risks, and one embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is the main body of the clothes dryer, 2 is a drying chamber provided inside the main body 1, 3 is a door that can be opened and closed to cover the clothes input port 4 of the drying chamber 2, and 5 is a high-frequency generator provided at the bottom of the drying chamber 2. Equipment (magnetron)
The object to be dried in the drying chamber 2 is irradiated with high frequency waves. 6 is an antenna, 7 is a waterproof cover made of polypropylene, and 8 is a fan disposed inside the main body 1 at the lower part. 5 and sends air into the drying chamber 2 through an intake hole 2a provided at the bottom of the drying chamber 2. The air sent into the drying chamber 2 is then pumped out of the machine through exhaust holes 2b and 1b provided at the top of the drying chamber 2 and the main body 1. discharge to.

Reference numeral 11 denotes a hanger holder from which the hanger 9 is suspended.The hanger holder 11 is formed with a substantially L-shaped handle arm 12, and this handle arm 12 is rotatably pivoted by a bearing 13 provided on the upper side wall of the drying chamber 2. supported. Reference numeral 14 denotes a pulley fixed to one side of the handle arm 12, and this pulley 14 is driven by a motor pulley 16 and a belt 17 by a motor 15 provided at the inner bottom of the main body 1.
Rotationally driven through. And this pulley 1
4 rotates the hanger holder 11. As a result, the clothing 10 undergoes rotational movement, so that concentrated partial heating by high frequency waves is eliminated, and uneven drying is reduced. Further, the ventilation effect will not be reduced due to close contact with clothing.

Reference numeral 18 denotes an L-shaped lever having one end in contact with the bottom of the drying chamber 2 and a spring 19 secured to the other end. The lever 18 is rotatably supported, and normally one end of the lever 18 is attached to the drying chamber 2.
It is urged by a spring 19 so as to contact the bottom of the. A rod 21 is connected to the other end of the lever 18 and extends between the front surface of the drying chamber 2 and the door 3. This rod 21 is normally biased by a spring 19 so as to sink into the main body 1. There is. 22 is an actuator for the door switch 23, and this actuator 22 is pushed by a protrusion 3a provided on the door 3 to operate the door switch 23 when the door 3 is closed.

In the above configuration, when the power switch is left on and the door 3 is closed, high frequency waves are irradiated into the drying chamber 2 from the high frequency generator 5. However, if a child enters the drying chamber 2, Due to the weight F, the bottom surface of the drying chamber 2 is lowered as shown by the dotted line in FIG. 2, and the lever 18 is rotated clockwise against the spring force of the spring 19 to reach the state shown by the dotted line.
As a result, the rod 21 connected to the other end of the lever 18 rises and projects between the front surface of the drying chamber 2 and the door 3. As a result, the door 3 cannot be closed due to the presence of the rod 21, so the door switch 23 is not activated and the high frequency generator 5 is not energized. When the load F in the drying chamber 2 is removed, the bottom of the drying chamber 2 returns to its original state, and the lever 18 and rod 21 also return to their solid line states due to the spring force of the spring 19. As a result, the door 3 can be closed, so the door switch 23 can be operated and the high frequency generator 5 can be energized.

As described above, according to the present invention, even if a child accidentally enters the drying chamber, the rod can be projected between the front surface of the drying chamber and the door by displacement of the bottom of the drying chamber, and
Since the door is prevented from being closed, it is possible to provide a highly safe clothes dryer that uses high frequency waves.

Claims (1)

[Claims] 1 A drying chamber provided in the main body, a door that can be opened and closed to cover the clothes input port of the drying chamber, a door switch that closes the electrical load circuit of the clothes dryer when the door is closed, and an air intake and exhaust system in the drying chamber. and a high-frequency generator that irradiates high-frequency waves to the objects to be dried in the drying chamber. This clothes dryer has a structure in which a rod that appears between the drying chamber and the door is interlocked with each other, and when the bottom of the drying chamber moves downward, the rod protrudes between the front surface of the drying chamber and the door, so that the door is not blocked.
