Among the high-frequency heating devices, those provided with an electric oven or a gas oven are particularly prone to leakage of hot air and smoke from around the door during heating of the oven, as shown in FIG. The door 3 corresponding to the opening front plate 2 of the heating chamber 1 was provided with a gasket 4. FIG. 3 is a detailed view of a portion A in FIG. 2, and FIG. 4 is a sectional view taken along the line BB of FIG. As shown in FIG. 4, the gasket 4 is attached to a choke cover 5. The door frame 6 is in close contact with the heating chamber opening front plate 2 (FIG. 2) when the door is closed to prevent radio wave leakage. (Although a choke structure 6a is further formed on the door frame 6 with respect to the prevention of radio wave leakage, this is not particularly mentioned here.) The gasket 4 slightly projects from the door frame 6, and the gasket 4 4 adheres while deforming corresponding to the opening front plate 2.

う。Problems to be Solved by the Invention When the door is closed, it is necessary to simultaneously achieve close contact between the door frame 6 and the opening front plate 2 and close contact between the gasket 4 and the opening front plate 2 as shown in FIG. Gasket 4
The projection height differs between the corner portion 4a and the straight portion 4b.

部を小さくしなければならないという問題があった。FIG. 5 is a cross-sectional view taken along the line CC of FIG. 3. As shown in FIG. 5, the corner portion has a raised protrusion height due to deformation of the gasket 4. Therefore, there is a problem that the close contact between the door frame 6 and the front plate 2 of the opening of the heating chamber is deteriorated, and the electric wave leakage is increased. Further, in order to prevent deformation at the corners of the gasket 4, it is necessary to take a considerably large corner R, which significantly reduces the visible area of the upper door of the radio wave seal structure, or reduces the heating chamber opening. Has to be reduced.

口部前板との密着を同時に向上させるものである。The high-frequency heating device according to the present invention is characterized in that, in the door, the mounting height on the side of the door on which the gasket is mounted is different from the straight portion at the corner of the door, so that the projecting height of the straight portion and the corner is reduced. It is possible to make the contact between the gasket and the front plate of the opening of the heating chamber and the adhesion of the door frame and the front plate of the opening of the heating chamber at the same time.

る。Embodiment Hereinafter, a high-frequency heating apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment for solving the problems of the prior art example shown in FIG. 5, in which the gasket mounting portion of the choke cover 8 is provided in such a manner that the protruding height of the gasket 7 is higher than the straight portion at the corner. It is falling down. The cross section 7a of the corner gasket 7 is deformed and elongated in the same manner as in the conventional example, but the height of the protrusion is the same as that of the straight part by dropping the choke cover 8 downward. By forming this configuration at four corners, the protruding height of the gasket can be made constant over the entire circumference. Therefore, incomplete adhesion between the gasket and the front plate of the opening of the heating chamber due to the end contact of the corner of the gasket and incomplete adhesion of the door frame and the front plate of the opening of the heating chamber can be eliminated.

のにおいては実用上きわめて有利なものである。Effect of the Invention As described above, the high-frequency heating device of the present invention makes it possible to keep the height of the projection constant by dropping the gasket of the door door at the corner, thereby making the door frame close to the front plate of the opening of the heating chamber. As a result, the amount of radio wave leakage from around the door could be reduced. In addition, due to the improved adhesion, the contact area between the door frame and the front plate of the opening of the heating chamber to prevent radio wave leakage can be reduced, and the opening of the larger heating chamber and the visible window of the door can be made larger. It is also possible to make it easy to see the heating chamber. In addition, improved adhesion between the gasket and the front plate of the opening of the heating chamber reduces hot air leakage in the heating chamber, shortens the rise time to the temperature set in the oven, and reduces energy consumption during high-temperature heating. I was able to. In addition, dirt around the door due to steam or oily smoke and dirt in the air in the room in use can be remarkably reduced. Further, the shape at the time of manufacturing the gasket itself can be manufactured in the same shape without being conscious of the linear portion and the corner portion when the door is mounted. Therefore, it is a simple extruded product having the same cross-sectional shape and can be manufactured at low cost. As described above, not only the high-frequency heating apparatus but also an apparatus provided with an electric oven or a gas oven is extremely advantageous in practical use.
