種々の方策をとつていた。2. Description of the Related Art In FIG. 3, a general external perspective view of a high-frequency heating device, there is a door 3 at the front opening of a heating chamber 2 of the main body 1 of the device, and an operation panel 17 is located near the door 3. The operation panel 17 includes a time display section 5, operation keys 6, and a door opening button 7. FIG. 4 shows the structure of the operation panel 17 section.
A back plate 18 provided to prevent static electricity from entering the electronic circuit section is attached to the back surface of the operation panel 17, and then the electric circuit board 13 is attached. When using a high-frequency heating device, water may be accidentally splashed on the operation panel 17 or spilled from above. At that time, various measures were taken to prevent the electronic circuit from malfunctioning and becoming uncontrollable.

ルミ箔テープ１０を操作パネル１７と、シヤーシ
１１との隙間１２の上に貼付けていた。 As shown in FIG. 5, an example of a measure conventionally used is to operate an aluminum foil tape 10 to prevent water from entering between the upper part of the operation panel 17 and the exterior plate 8 of the main body 9 (as shown by the arrow). It was attached above the gap 12 between the panel 17 and the chassis 11.

まうことすらあつた。Problems to be Solved by the Invention However, not only is it time-consuming to apply the aluminum foil tape 10, but if the aluminum foil tape 10 is pasted out of position or forgotten, water will enter through the gap 12, causing damage to the electric circuit board 13. Water splashed onto the various parts 14 on top, causing the circuits to shoot out, malfunctioning, and sometimes even causing the microcomputer 15 to become uncontrollable.

果たせなくなるという問題があつた。 In order to solve the above-mentioned drawbacks, as shown in FIG. Another method was to extend the end face and sandwich it between the exterior plate 8 and the chassis 11. (Japanese Patent Publication No. 59-232606)
However, even with this method, since the back plate 18 is a sheet metal component, although it is initially able to prevent water from entering as intended, there is a risk of corrosion due to adhesion of moisture, and changes over time. This was not a perfect solution, as cracks were created through which water could infiltrate. Moreover, the operation panel 1
7 and the exterior plate 8, but because the color of the operation panel 17 and the exterior plate 8 (white, red, etc.) and the color of the back plate 18 (silver) are different, even a small gap may occur. The difference in color was noticeable and the appearance was extremely unsightly. If the back plate 16 is painted or plated in the same color as the exterior plate 8, etc., the problems of corrosion and appearance will be solved;
On the other hand, there was a problem in that there was no guarantee that the grounding could be established reliably, and the device could no longer fulfill its original role of preventing malfunctions and failures caused by static electricity.

This completely eliminates malfunctions and destruction. Further, since the upper end surface of the operation panel is extended, it can be easily molded at the same time as the operation panel is molded, and there is no strange appearance.

As shown in Fig. 1, a back plate 16 for preventing static electricity is attached to the operation panel 4 whose upper end surface is extended, and an electronic circuit board 13 is attached after that, and the configuration is completely unchanged from the conventional one. points have been resolved. FIG. 2 is a side sectional view. Since the upper end surface of the operation panel 4, which is a resin molded product, is extended and held between the exterior plate 8 and the chassis 11, for example, before or after heating,
Even if an object to be heated is placed on top of the main body of the device and water is spilled (as shown by the arrow in Fig. 1), the upper end extension of the first operation panel 4 will act as a cover, and the electronic circuit board 1 will be protected.
No water is sprinkled on 3. In addition, there is no need to apply aluminum tape during assembly or service as in the past, so there is no chance of the tape tearing or forgetting to apply it. Furthermore, corrosion and poor appearance, which occur when the upper end of the back plate 16 is extended, are completely eliminated.

の高い機器となる。(2) By extending the upper end of the operation panel, which is a resin molded product, it is possible to prevent water from entering.
It can be extended at the same time as the operation panel is formed. Therefore, there is no need to add other parts or complex bending for sheet metal structures, making it extremely simple and inexpensive, and also improves ease of assembly, serviceability, and mass production. It is an expensive device.

常に良くなり、商品価値の高い機器となる。(3) Extend a part of the operation panel, which is an exterior part,
Moreover, by adopting a configuration in which the exterior panel is sandwiched between the exterior panel and the chassis, the gap between the operation panel and the exterior panel that inevitably occurs is filled with the same color as the exterior components, so the exterior appearance is very good. This makes it a device with high commercial value.
(4) 延出部品が樹脂なので板金構成物の時のよう
にサビや腐食による亀裂の発生がなく、経時変
