Conventional configuration and problems Conventional high-frequency heating devices, so-called microwave ovens, prevent leakage of high-frequency waves through close contact between the front plate of the heating chamber and the sealing plate of the door provided opposite it, and prevent leakage of high-frequency waves from occurring inside the heating chamber. Prevents water vapor and hot air from escaping outside the heating chamber. However, now that the industry is dominated by composite products that add oven functions, grill functions, steam functions, etc. to microwave ovens,
If extremely high-temperature air, steam, smoke, etc. leaks from around the door to the outside, the door components and other parts will become hot, which will not only cause discomfort to the user but also pose a risk of burns. In the case of water vapor, it adheres to the surrounding area and the operating section becomes cloudy, and in the case of oil smoke, the operating section becomes stained with oil, which causes problems in terms of usability. Naturally, it is also necessary to improve the heat resistance of each component, which may pose a major obstacle in terms of quality and cost. Recently, there are many microwave ovens with forced hot air circulation on the market. In the case of this hot air type, when comparing the pressure inside the heating chamber with that of a conventional open range, there is a tendency for the pressure inside the heating chamber to increase.Of course, the high temperature inside the heating chamber, steam, oil smoke, etc. will escape from the gap between the heating chamber and the door. It becomes easier to leak. In this case, in addition to the above-mentioned disadvantages, the time to reach the set temperature inside the refrigerator (rise time) is delayed accordingly, and the cooking time is also increased, resulting in a large amount of energy loss, so-called low thermal efficiency.

Figure 1 shows a gas sealing gas seal 4 (hereinafter referred to as a gasket) made of a heat-resistant comb installed between a radio wave sealing plate 1 and a door frame 3 provided on the outside thereof and forming a traveling wave attenuation groove 2. . When the door is closed, the surface of the radio wave sealing plate 1 and the front plate of the heating chamber (not shown) almost come into contact with each other, and at this time, the protruding surface of the gasket 4 is pushed by the front plate of the heating chamber, and the surface of the heating chamber front plate is pushed into the radio wave attenuation groove. pushed inside. In this case, there are the following problems.

(1)支持部を49口と2ケ所要し、これを全面に設け

(3) If the cross-sectional shape of the gasket is complicated and it is installed around the entire circumference, the molding is limited to upper and lower molds (including corner radius), and the depth dimension 4. It also requires a lot of space, and the shape is large, resulting in high costs including the mold.

FIG. 2 shows another conventional example in which a gasket 4 is once installed in a gasket attachment groove provided in a door opening closing body 5 made of an electrically conductive material, which is an opening closing body for a radio wave attenuation groove 2, and then the radio wave is It is installed around the entire circumference of the seal plate 1 so as to be sandwiched between the flange and the back surface of the radio wave seal plate. In this case, although the structure is simpler than the conventional example mentioned above and the ease of installation is improved, (1) the sea/l/ portion is semicircular and unstable in shape;
Sealing performance may be impaired due to wrinkles, warpage, etc. due to heat shrinkage or other factors.

(1) Since the cross section of the hollow part is square, when compressed when the door is closed,
In particular, complex deformation occurs between some corners and straight parts, (
(Twisting, etc. causes surface contact and contact, and the contact becomes unstable in the middle.) This may cause problems in terms of sealing performance.

(2)中空部のシール面裏面側に圧縮時の逃げのだめの

(3) Due to the rectangular cross-section, the compression allowance is large and complex deformation occurs when the door is closed, so if the door is left closed for a long time, the rectangular hollow part will not be able to recover properly, especially in such a state, the high heat will cause damage. The hollow part remains deformed.

(4) Due to the shape of the compression reservoir to accommodate the compressed portion in the space E of the compression reservoir, a certain distance e2 is required between the groove of the reservoir of the flange bottom of the radio wave sealing plate 1 and the sealing portion. The 7-lunge of the radio wave seal plate must be inserted into the 7-lunge housing groove provided in a part of the 7-lunge housing groove, making installation extremely difficult.

(5) Because the mounting seat requires a fairly thick wall to stabilize it during compression, the height of the wall increases accordingly, and if it is still installed around the entire circumference,
Because of the thick wall and the square shape of the hollow portion, it is necessary to make the corner R with a considerably large curvature, which poses a major restriction in terms of design.

FIG. 5 shows an enlarged sectional view of the main part, and the packing 6 according to the present invention has an arbitrary diameter necessary for cooling, a sealing part having a wall thickness t made as thin as possible within a range that can always maintain this diameter, and a door sealing part. The radio wave seal plate 1 of the mounting part consists of a mounting part that is mounted in advance in the mounting groove provided in the opening closing body 5 and then clamped with the radio wave seal plate 1 described above.
, its flange Wg, and the mounting groove of the door opening closing body 5 (the clamping part surrounded by and is thicker than the wall thickness (t2) of the connecting part with the seal part, and the tip of the 7 langes g and the groove f are In addition to the distance between the bottom surfaces (t3), a thick wall part a that does not come out even when an external force is applied is provided, and a gap is provided around the entire circumference of the groove f except for the bottom surface, so that there is enough space to prevent wrinkles, deformation, etc. due to heat shrinkage. Thin ribs b and c are provided along the side wall of the mounting groove f to be press-fitted.

By having this structure, the gap around the entire circumference does not press down on the attached part, so there is no wrinkles or deformation caused by differences in contraction due to thermal expansion, and the seal part always maintains its original shape because of its circular hollow cross section. The fact that the multiple force that tries to return to the state is greater than in the conventional example, the seal part maintains a stable shape and sealing performance is improved.By providing the thick part a as described above, , a gap is provided around the entire circumference so that it will not come out due to external force (deliberate pulling or force applied for cleaning) even if it is not completely pressed down.Furthermore, the rig is designed to be press-fitted into the side of the groove. , c, it is difficult to remove the rib in the removal direction if it is press-fitted as shown in the figure, even after it is installed in the groove f in advance and before the next work, the installation of the radio wave seal plate 1, or when it is directly attached. It bends while being in pressure contact with the side wall, and with the addition of the frictional force due to the rubber material of the gasket 6, it can be inserted into the groove several times, making it very easy to wear.
