Description

[Detailed Description of the Invention] This invention relates to a high-frequency heating device with an improved structure of a viewing window in a door body.

As shown in FIG. 1, the high-frequency heating apparatus is provided with a viewing window C on the front door of the main body a, so that the inside of the high-frequency heating chamber d can be observed.

The structure of this viewing window C in a conventional high-frequency heating device is as shown in FIG.

That is, a punched board with a large number of pores g... is formed on a door body f having a peep hole e in the center, and a choke structure for preventing leakage of radio waves from the high frequency heating chamber d. A choke plate i is welded by spot welding, and an inner barrier j made of a transparent material is sandwiched between the punched plate and the cover and fixed to the door body f with a plurality of screws 1.

That is, the periphery of the peep hole m in the cover is made to protrude inward,
The periphery of this protrusion n was pressed down with the screw 1.

By the way, it is difficult to maintain a completely airtight contact between the cover and the inner barrier j, and the high frequency heating chamber d
In order to prevent steam generated from the food inside from entering and causing fogging of the inner barrier j, as shown in FIG. There is a sealing material p such as silicone rubber between the main body f.
needed to be filled.

Therefore, there is a drawback that assembly work efficiency is reduced.

This invention was made in consideration of the above circumstances, and its purpose is to integrally mold the inner barrier of the door body viewing window and the mounting part for pressing this inner barrier against the door body. In addition, the present invention aims to provide a high-frequency heating device that prevents steam generated in the high-frequency heating chamber from entering the door body by smoothing the inside of the door body, and improves assembly workability.

An embodiment of this invention will be described below with reference to the accompanying drawings.

Reference numeral 1 in FIGS. 5 and 6 is a door body, and the top of this door body is adapted to close an opening 4 of a high-frequency heating chamber 3 provided inside the main body 2.

In addition, the door body 1 is constructed by welding a chalk plate 8 having a peep hole 7 to the inside of the door body 6 having a peep hole 5 in the center, and
A punching plate 10 having a large number of pores 9 is welded to the outside thereof.

On the inside of the chalk board 8, the part facing the central peephole 7 is made of a transparent synthetic resin material, and the periphery of this viewing port part 11 is a mounting part 12 made of an opaque synthetic resin material. An inner barrier 13 is provided and is fixed to the door body 6 with mounting screws 14.

The periphery of this inner barrier 13 comes into contact with the inside of the door body 6 to prevent foreign matter from entering the inside of the door body 1.

In addition, as shown in FIG. After being inserted into a mold, the mold for the viewing window 11 is filled with a transparent synthetic resin material and heated, which is a well-known method.

Moreover, the inner surface of this inner barrier earthwork is formed smoothly.

Further, an outer barrier 16 made of a transparent resin material is fixed to the outside of the door body 6 by a decorative frame 17 provided on the peripheral wall 6a of the door body 6, and the inside of the high-frequency heating chamber 3 can be observed from the outer barrier 16. It is now possible to do so.

As explained above, by providing an inner barrier on the inside of the door body that integrates the viewing window made of a transparent material and the mounting portion made of an opaque material and has a smooth inside part, it is possible to prevent steam from inside the door body. Intrusion is prevented and fogging does not occur on the inner and outer barriers.

Additionally, food does not adhere to the inner surface of the inner barrier, making cleaning easier.
