１の下面を保持している。<Prior art> Conventionally, as shown in FIG. 1, in a microwave oven with a heater that focuses on heating, an insulator 1 having a horizontal arm portion is mounted on the ceiling of an oven body 6 by being held by a mounting bracket 4. The free end of the metal reflector plate 2 with the infrared heater 3 attached is placed and held on the horizontal arm of the insulator 1, and the opposing edges of the mounting bracket 4 are in complete contact with the insulator 1. This holds the bottom surface of the insulator 1.

起こし、使用不能となることもあつた。 In the above configuration, if the microwave is guided from the magnetron 5 into the oven 6, the insulator mounting bracket 4
The metal reflecting plate 2 is in a state where it is exposed to an electric field, and electric field concentration occurs at the opposing edges of the mounting bracket 4, and between the edge of the mounting bracket 4 and the reflecting plate 2, A trackside discharge (arc discharge) may occur via the surface of the insulator 1. In particular, the more the insulator surface becomes contaminated with deposits, the more pronounced this phenomenon becomes.As a result, not only does the discharge light and sound give a sense of fear to the user, but the insulator is also subject to thermal distortion due to local overheating. In some cases, they were damaged or completely shattered, causing poor insulation and rendering them unusable.

とは困難であつた。 Therefore, in order to eliminate such discharge on the insulator surface, the surface distance (creepage distance) from the edge of the mounting bracket 4 in contact with the insulator 1 to the reflector plate 2 via the insulator surface should be made as long as possible. is important. However, if we simply try to increase the creepage distance between the reflector and the mounting bracket, the external dimensions of the insulator itself will become too large, creating space problems and increasing costs, so it is difficult to solve all of these issues at once. was difficult.

The mounting bracket 4 is of a groove type with an opening on the lower surface, and its upper surface is fixed to the ceiling of the oven 6 by screws or other appropriate means, and both legs of the insulator are mounted on both end edges 4' of the opening. A bent free end of a metal reflecting plate 2 made of a stainless steel plate, a galvanized steel plate, etc., to which an infrared radiant heater 3 is attached is mounted on the tip of the horizontal arm.

The electric field of the microwave is concentrated and the metal fitting 4 becomes electrically charged.
The electric field tends to concentrate particularly at the edge 4' of the
If the conventional example shown in FIG. 1 has a wide contact support structure, discharge (arc discharge) will occur from the edge 4' to the reflector 2 via the creeping surface a of the insulator (intermediate support). If the creepage distance a is short, the discharge will start immediately.
