Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a microwave oven.

(b) Conventional technology Generally, in a microwave oven, a lighting means for illuminating the inside of the heating chamber (see Japanese Utility Model Publication No. 47-31727, etc.);
It also requires many parts, such as abnormal high temperature detection means (see Japanese Utility Model Application Publication No. 55-26887) for detecting abnormal high temperature of the magnetron, and the structure is complicated.

(c) Problems to be Solved by the Invention The present invention aims to simplify the structure of the microwave oven as much as possible by fixing the lighting means and the abnormally high temperature detection means in a compact manner.

(d) Means for solving the problems The microwave oven of the present invention comprises a heating chamber, a magnetron for supplying microwaves into the heating chamber, a lamp section and a socket section, and lighting means for illuminating the inside of the heating chamber; The lighting means is comprised of a fixed wall to which the lighting means is fixed via a socket part, and an intermediate wall located between the lamp part and the socket part, and a lighting means fixing body fixed to one wall of the magnetron, and the intermediate wall. an abnormally high temperature detection means fixed to a surface on the socket side side of the magnetron for detecting an abnormally high temperature of the magnetron; a cooling means disposed closer to the detection means than the intermediate wall and cooling the magnetron, the illumination means, and the detection means; It is characterized by having the following.

(E) Effect In the present invention, the abnormal high temperature detection means is compactly fixed in addition to the illumination means to the illumination means fixed body fixed to one wall of the magnetron, so the structure can be simplified. Moreover, since the detection means is fixed to the surface of the intermediate wall of the fixed body on the socket side of the illumination means, and the cooling means is disposed on the socket side, as a result, the detection means can be connected to the magnetron and the illumination. It can be efficiently cooled by the cooling means together with the cooling means. Furthermore, if the magnetron reaches an abnormally high temperature despite such cooling, the detection means detects the abnormally high temperature via the fixed body.

(f) Examples The drawing shows a microwave oven according to an embodiment of the present invention.

Microwaves are supplied into the heating chamber 2 of the microwave oven body 1 from a magnetron 3 fixed to the right side wall 2a of the heating chamber. The magnetron and the like are cooled by a cooling fan 4, and a compact component 5 is disposed on the lower wall of the magnetron 3.

The details of the compact component 5 will be explained based on FIGS. 3 to 7. A hanging piece 8 is provided on the left front side.
and L-shaped locking pieces 9a, 9b on the right rear side.
A bending fixed body 6 consisting of a circular horizontal wall 7 and a vertical wall 10 is attached to the lower wall of the magnetron 3.
It is fixed via screws (not shown). A screw hole 8a is formed in the hanging piece 8.

Further, a bent illumination means fixing body 11 is fixed to the bending fixing body 6, so that the illumination means fixing body 11 is substantially connected to the magnetron 3 via the bending fixing body 6. is fixed to the bottom wall of the The illumination means fixed body 11 has a horizontal fixed wall 12
, a right hanging piece 13 at the rear right side, two lower seat pushers 14a and 14b on the right side that are formed in the fixed wall 12 and have screw holes, and a right-angled piece that is narrow at the rear and has a screw hole 16a at the front. 16 and a hanging piece 15 formed thereon. In the illumination means fixing body 11, the narrow portions of the right hanging piece 13 and the left hanging piece 15 are locked by the L-shaped locking pieces 9a, 9b of the fixing body 6, and the right-angled piece 16 is fixed to the screw 16. It is fixed to the stationary body 6 by being screwed onto the hanging piece 8 of the stationary body 6 at ''.

Furthermore, the horizontal fixed wall 12 of the illumination means fixed body 11
The inside of the heating chamber 2, which is composed of a lamp part 17a and a socket part 17b, is connected to a small hole 2 in the right side wall 2a of the heating chamber.
An illumination means 17 is fixed for illuminating via b, 2b, . . . The fixing is done by attaching the leg 18 of the socket part 17b to the lower seat pressing part 14 with screws 19, 19.
This is done by screwing onto the holes a and 14b. In this case, the socket part 17b is the seat pressing part 14a,
Since the parts other than 14b are spaced apart from the magnetron 3, heat from the magnetron 5 is difficult to transfer. In the above fixing, the left hanging piece 15 is connected to the lamp part 17a of the illumination means 17 and the socket part 17.
As a result, the lamp part 17a is covered by the vertical wall 10 of the fixed body 6 and the left hanging piece 15 of the illumination means fixed body 11, and the inside of the heating chamber 2 is light is reflected more efficiently.

Furthermore, the left hanging piece 15 of the illumination means fixing body 11
An abnormal high temperature detector 20 for detecting an abnormal high temperature of the magnetron 3 is attached to the wide portion of the magnetron 3 on the surface facing the socket portion 17b. In this case, the cooling fan 4 is placed closer to the detector 20 than the left hanging piece 15, and the magnetron 3, illumination means 17, and detector 20 are efficiently cooled from the rear (FIG. 2). be done. and,
If the magnetron 3 reaches an abnormally high temperature despite such cooling, the detector 20 detects the abnormally high temperature via the fixed bodies 6 and 11, and then the detector 20 forces the magnetron 3 to drive. It is strictly prohibited.

To explain the procedure for assembling the compact component 5, first, the fixing body 6 is fixed to the lower wall of the magnetron 3 with screws. On the other hand, the lighting means fixed body 1
1, the illumination means 17 and the detector 20 are fixed as described above. Thereafter, the illumination means fixing body 11 is fixed to the fixing body 6 as described above.

(g) Effects of the invention According to the invention, the lighting means fixing body fixed to one wall of the magnetron has a fixed wall to which the lighting means is fixed via the socket part, and an intermediate part between the lamp part and the socket part of the lighting means. An intermediate wall located at the magnetron is provided, and abnormal high temperature detection means for detecting abnormal high temperature of the magnetron is fixed to the intermediate wall.
In addition to the illumination means, the abnormal high temperature detection means can be compactly fixed to the illumination means fixing body, and the structure of the microwave oven can be simplified.

Further, the intermediate wall, which is located between the lamp section and the socket section of the illumination means and to which the abnormally high temperature detection means is fixed, covers a part of the lamp section and efficiently reflects the light from the lamp section into the heating chamber. By also serving as the intermediate wall for fixing the abnormally high temperature detection means, it is possible to easily see the heating state in the heating chamber.

Furthermore, the abnormal high temperature detection means is fixed to the surface of the intermediate wall on the socket side, and therefore, the cooling means arranged on the side of the abnormal high temperature detection means from the intermediate wall efficiently operates together with the magnetron and the lighting means. Can be cooled.
