Description

[Detailed description of the invention] The present invention relates to a radio wave leakage prevention mechanism installed in a high-frequency heating device to prevent instantaneous leakage of radio waves when the door is opened during heating, and has a safe, easy-to-use, and simple configuration. The purpose is to

Conventionally, various methods and structures have been known to prevent radio wave leakage in high-frequency heating devices, such as a door lock mechanism with a built-in pantograph mechanism, but these have a large number of structural parts and are difficult to use.

The present invention eliminates the above-mentioned drawbacks of the conventional art, and one embodiment of the present invention will now be described with reference to the accompanying drawings.

In the figure, 1 is a heating device main body, 2 is a heating chamber provided in the main body 1, and a door 3 is provided at the front opening of the heating device via a hinge 4 so as to be openable and closable.

A door handle 5 is movably provided on the door 3, and is equipped with hinge mechanisms 6 and 7 for rotatably supporting the handle 5 inside.

8 is a dog-shaped door lock key that is directly connected to the handle 5, and a door lock switch 9 is equipped on the side of the main body opposite to the door lock key 8, and by moving the handle 5, the door lock key 8 can be made to come out and go. This opens and closes the door lock switch 9.

As is clear from FIG. 3, the door lock key 8 is provided in a bulge formed on the upper end surface of the door, and is housed in the upper end surface of the door as a whole so that the tip does not protrude from the door. be.

Therefore, when the door 3 is closed, the door lock key 8 is almost hidden.

A magnetron 11 10 is provided on the upper surface of the heating chamber 2 and is a heated object provided within the heating chamber 2 .

The door lock key 8 is always urged upward by a spring (not shown), and has a hole 13 into which a hook 12 provided on the main body is hooked.
is provided near the contact portion 8a of the actuator 14 of the door lock switch 9.

Reference numeral 15 is a meat filling part that stores the door lock-1i--8.

In the above configuration, when the door 3 is opened during cooking, when the user pulls the handle 5 toward the user, the door lock key 8 is lowered against the elasticity of the spring.

Therefore, the door lock switch 9 pressed by the tip of the door lock key 8 is turned off, the power supply circuit is cut off, and the door 3 is then opened, thereby reliably preventing leakage of radio waves when the door is opened. Can be done.

As explained above, the present invention allows the door to be opened with a one-touch operation by simply moving the door handle while reliably preventing radio wave leakage.Also, since the door lock key is directly connected to the door, the number of parts can be reduced. Moreover, the operating stroke of the door lock key remains constant no matter which part of the handle is moved, making it possible to provide a product that is easy to use.

In addition, by incorporating the hinge of the handle inside the handle, the pantograph mechanism is built in, resulting in a simpler structure with less wasted movement than a handle structure that has a movable part and a fixed part, and is also superior in design. can be made into something.

Furthermore, since the door lock key is housed without protruding outside the door, the user will not be able to hook clothes or the like on the door lock key and cause the device to fall over while the door is open.

Also, since the door lock key is hidden when the door is closed, the design is also excellent.
