ニットを収納するスペースは充分あるのである。BACKGROUND OF THE INVENTION Conventional high-frequency heating devices generally have an exterior plate or a bottom plate outside the heating chamber, which limits the ability to reduce assembly time and component costs. To improve these, there is a so-called horizontal type in which an electrical parts storage chamber is placed next to the heating chamber, and a heating chamber made of one piece is disclosed in Japanese Patent Application No. 59-105036. It is a so-called vertical type with an electrical parts chamber at the bottom of the heating chamber, and the weight is 11? ll! 59-1193
There is one from Publication No. 19. The former horizontal type has a single-layer heating chamber, but even in the conventional double-structured type, it is normal design to have a latch unit in the electrical parts room. Even the vertical type has enough space to store the latch unit.

という問題があった。Problems to be Solved by the Invention However, in such a high-frequency heating device, the heating chamber has a single-layer structure as in the former case, and in the case of a vertical type high-frequency heating device as in the latter case, the heating chamber and electrical parts storage chamber are not large enough. As the structure became more and more simplified, if it was installed in a position like the door key 20 shown by the dotted line in Figure 1, it would be impossible to install the latch unit in a place that is already inside the heating chamber 3 and would be exposed to high frequency waves. It is self-evident that high frequencies can destroy the switches in the latch unit, or high frequencies can reach circuit wires and emit unnecessary radiation, causing noise on televisions and radios, making countermeasures extremely complicated. There was a problem that it was expensive.

装置を提供することを目的とする。The present invention solves these conventional problems by providing a door switch inside the exhaust guide outside the heating chamber, which has a single-layer substantially square-shaped configuration. It is an object of the present invention to provide a high-frequency heating device which has excellent assembly workability and greatly contributes to a reduction in parts costs by providing a through-hole.

ないのである。With this configuration, only the heating chamber 1 is independent in a single-piece configuration, and other electrical components are stored in the electrical compartment 2. Therefore, first complete the assembly of each component in the electrical compartment 2, and then operate the Attach the unit on panel 4. After that, place the heating chamber 1 on top of the electrical chamber 2, fix them with screws, etc., attach the door 3 to the front opening, and insert the switch operation part 11 from the rear of the heating chamber 1 and hold it through. , the assembly of the product is completed by attaching the exhaust guide 9 to which the door switch 1o is attached. That is, since the assembly line assembles each unit, the assembly line can be shortened and the mass productivity is very good. In addition, since the door switch 10 is not installed inside the heating chamber 1, it is not exposed to high frequency waves, so the door switch 10 is not damaged by high frequency waves, and the circuit wires are exposed to high frequency waves, resulting in unnecessary radiation. It does not cause any interference to the radio.

性の高い機器を提供できるのである。Effects of the Invention As described above, the high-frequency heating device of the present invention includes a door switch provided in the exhaust guide outside the heating chamber, which has a substantially square-shaped one-piece structure.
A switch operating section for operating the door switch is provided through the heating chamber. Therefore, since it is not exposed to high frequencies, the door switch itself will not be damaged by high frequencies, and the circuit tubes and wires connected from the door switch to each circuit will not be exposed to unnecessary radiation due to high frequencies, and there will be no interference with television and radio. be. In addition, since the door is installed in the front of the heating chamber and the switch is installed in the rear, it responds very sensitively to the movement of the door, making it a highly sensitive door switch.It has good immediate switching performance, so it prevents leakage of electromagnetic waves from around the door. The circuit is also at a very low level.
It can be used as a FF device, making it an extremely safe device. In addition, since the exhaust guide is used as a switch mounting part and a cover for the switch mounting part, cost increases can be kept to a minimum, and the concept of unitization as a door, heating room, electrical room, and exhaust guide unit has been improved. It is possible to assemble the parts while they are still in use, making it possible to provide equipment that is highly mass-producible.
