周波の発生は停止する構造となっている。A plastic door outer frame 15 is arranged on the outside of the door 6. An outer screen 16 made of resin such as acrylic or reinforced glass is attached to the door outer frame 6 and the door outer frame 16. being held in place. The door outer peripheral frame 16 is fixed from the inside of the door outer frame 6 with screws 17. A part of the body 18 and a lower sash 19 are arranged on the periphery of the door 5 in parallel with the door outer peripheral frame 15, and these are all made of metal material. 20 is a handle, 21 is a timer knob for setting heating time provided on the operation panel 22, and 23 is a heating start button.When heating the object to be heated with high frequency, set the timer knob 21 to the required time. When the heating start button 23 is pressed, the heating starts. When the timer goes off, the housing is structured so that if the door 5 starts to open during heating, the generation of high frequency waves will stop.

い程電波シール効果は良い。Furthermore, the high frequency generated in the heating chamber is
The radio wave is attenuated by the capacitive seal formed by the heating chamber opening surface 3 and the door inner frame 11 and the radio wave attenuation groove, and is safe with almost no leakage.
It has been experimentally confirmed that this is greatly influenced by the width of the passageway. That is, the smaller the gap ttet2 between the outer peripheral wall of the door outer frame 6 and the body 18 and the lower sash 19, the better the radio wave sealing effect is.

becomes large, at least 5111J in the conventional case
If the radio wave sealing performance is insufficient, it is also possible to place a radio wave absorber (not shown) in the middle of the radio wave attenuation groove 13 and inside the door outer frame 15. there were.

造を備えた高周波加熱装置を提供できるものである。The present invention solves the above-mentioned problems in the conventional example. In other words, it reduces the number of parts, improves workability, further improves the radio wave sealing performance, ensures safety, and offers a wide range of products with various designs. Therefore, it is possible to provide a high-frequency heating device with a door structure that can satisfy the customer's requirements.
以下本発明の一実施例を縦囲き扉を備えた高周波加熱装
置の例で第3図〜第5図により説明する。An embodiment of the present invention will be described below with reference to FIGS. 3 to 5 using an example of a high-frequency heating device equipped with a vertical enclosure door.

ー14が保持さ九ている。A door 5 is provided opposite the opening surface 3 of the heating chamber 2 and rotatable about a rotating shaft 4. The door has a metal outer door frame and a door inner frame 7 that are integrally formed by spot welding or the like, and is made of glass with a metal screen 8 consisting of a group of small holes and a U-shaped rubber frame 9 on the outer periphery. The inner screen 1o has a metal door inner frame 11 and a door middle frame 7 whose surfaces are treated with an insulating material.
It is clamped by a screw 12 between them. The whole area constituted by the door outer frame 6 and the door inner frame 11 is a radio wave attenuation groove 13, and the entrance thereof is held by a cover 14 made of a low dielectric material or heat-resistant plastic.

で、その下側は傾斜面となり、扉開閉時にサツシ−下1
9との距t2′が十分小さくなる角度となっている。- On the front side of the gal outer frame 6, there is a door front frame right 24, a left door front frame 26,
The lower door front frame 27 is spot welded and painted. The right door front frame 24 and the left door front frame 26 are bilaterally symmetrical, and have a substantially U-shaped cross section. Lower door frame 26
is configured to be flush with the right door front frame 24 and the left door front frame 26, and the lower side thereof is an inclined surface, so that when the door is opened and closed, the bottom 1
The angle is such that the distance t2' with respect to 9 is sufficiently small.

たつきを吸収すると共に、断面が略く字状の突部をもつ
扉前枠上27全圧入し上部のがたつきを吸収している。The outer screen 16 includes a door front frame right 24, a door front frame left 26,
It is inserted and held in a U-shaped groove formed in the lower right corner 26 of the front door frame, and the width a of the groove is larger than the thickness b of the outer screen. This is because when the outer screen 16 is made of tempered glass, it is necessary to allow a distortion of about 0.3% in the plane of the glass with variations in thickness of ±10×1. Therefore, in order to prevent the outer screen 16 from rattling, the lower ends of the spot welding surfaces of the right and left door front frames 24 and 26 are formed into a substantially dogleg shape to absorb the rattling of the lower part of the outer screen 16, and to The top 27 of the door front frame, which has a roughly doglegged protrusion, is completely press-fitted to absorb the rattling of the top.
特に扉前枠上2:rは中央付近にも略く字状の突部があ

水やほこりが入るのを防止すると共に、ガラス切断面が
見えないように覆っている。In particular, the upper part of the door front frame 2:r has a roughly doglegged protrusion near the center, which eliminates the gap between the door outer frame 6 and the outer screen 16 to prevent water and dust from entering. , the cut surface of the glass is covered so that it cannot be seen.
扉前枠上27を圧入後、ハンドル2oをネジで固足する
