Description

[Detailed Description of the Invention] The present invention relates to a cooking device such as a microwave oven that has a lighting lamp for illuminating the inside of the heating chamber through a through hole formed in the heating chamber. A transparent plate is provided to cover the heating to prevent oil, water, or other steam from leaking from the heating chamber to the outside or from adhering to the lighting lamp. The purpose of the present invention is to simplify the structure and facilitate assembly by making it possible to also fix the light-transmitting plate, and to prevent the adverse effects of heat conduction on the illumination lamp.

Hereinafter, an embodiment of the present invention in a microwave oven will be explained with reference to the drawings. In the drawings, 1 is a case of the microwave oven in this embodiment, 2 is a heating chamber, and inside thereof there is a space for placing food. A table 3 and upper and lower heaters 4 and 5 for external heating are provided.

6 is a door that opens and closes the front opening of the heating chamber 2, and 7 is a magnetron that is opened at the upper part of the outside of the heating chamber 2, and is designed to generate high-frequency energy for internal heating.

Reference numeral 8 denotes a through hole group consisting of a large number of through holes 8a formed in the front upper part of one side wall plate 2a of the heating chamber 2, and each through hole 8a
is so large that high frequency energy cannot pass through it.

As shown in FIGS. 2 and 3, 9 is a substantially rectangular light-transmitting plate disposed on the outer surface of the side wall plate 2a so as to cover the through-hole group 8, and is made of transparent heat-resistant glass. It's getting better.

Reference numeral 10 denotes a mounting bracket fixedly attached to the side wall plate 2a in order to grip and fix the lower edge and left and right side edges of the transparent plate 9.

Reference numeral 11 indicates a reinforcing member interposed and fixed between the bent portion 2b formed at the upper end of the side wall plate 2a and the reinforcing frame 12 provided on the top plate portion 1a of the case 1, and 13 indicates the intermediate portion of the reinforcing member 11. The entire mounting piece is approximately L-shaped, and its upper end portion is fixed to the portion by a pair of screws 14, and a socket 15 as an illumination lamp support portion is provided at the tip.

An illuminating lamp 16 is fitted into this socket 15 so as to face the transparent plate 9, and this illuminating lamp 16 and socket 15
A gap is provided between the transparent plate 9 and the transparent plate 9.

Further, the pair of screw insertion holes 17 of the mounting piece 13 through which the screws 14 are inserted have a cylindrical constricted portion 17 toward the reinforcing member 11 side.
The mounting piece 13 is in contact with the reinforcing member 11 only at this constricted portion 17a.

Reference numeral 18 denotes a holding piece that is bent toward the transparent plate 9 at the upper end of the mounting piece 13, and the transparent plate 9 is attached to the tip of the holding piece.
An L-shaped upper pressing part 18a that integrally presses the upper surface and front surface near the corners of the upper edge and the left and right side edges, and a flat plate-shaped lower pressing part 18b that presses the side end surfaces are formed. There is.

Therefore, the transparent plate 9 is connected to this holding piece 18 and the mounting bracket 1.
0, it is fixed so that it does not move.

In this way, the microwave oven of this embodiment is provided with the transparent plate 9 so as to cover the group of transparent holes 8, so that the lighting lamp 16 is prevented from being contaminated by leakage of water, oil, or other steam generated from the heated food. In addition, since the size of each through hole 8a is set to a size that does not allow high-frequency energy to pass through, it is possible to reliably prevent high-frequency waves from leaking outside the heating chamber 2.
It is possible to prevent an adverse effect on the function and life of the product.

Furthermore, since the illuminating lamp 16 and the socket 15 are supported via the mounting piece 13, even if the heating chamber 2 is heated during heating by the heaters 4 and 5, the heat is directly transferred to the illuminating lamp 16 and the socket 15. Therefore, the function and life of the illumination lamp 16 and socket 15 can be prevented from being adversely affected by heat.

Then, the mounting piece 13 is connected to the reinforcing member 11 at the constricted portion 17.
Since they are in contact only at H, the heat conduction to the mounting piece 13 can be extremely reduced, and the adverse effects of heat can be more reliably prevented.

Further, in this microwave oven, mounting brackets 10 are provided so as to grip only the lower edge and the left and right side edges of the light transmitting plate 9, and the mounting brackets 10 are provided above the position where the light transmitting plate 9 is disposed and on the other left and right sides. Since the opening is larger, the transparent plate 9 can be attached to the mounting bracket 10 very easily from the opening, and the mounting piece 13 for supporting the illumination lamp 16 has a
A presser piece 18 is provided that abuts near the corner of the upper edge of the transparent plate 9 and the left and right side edges and fixes the transparent plate 9 in cooperation with the mounting bracket 10. Therefore, the structure is extremely simple with a small number of parts, and the light-transmitting plate 9 can be installed simply by attaching the mounting piece 13 for supporting the illumination light in a predetermined position.
can be easily and reliably fixedly arranged at a position corresponding to the through hole group 8.

As detailed above, according to the present invention, it is possible to prevent the function and life of the lighting lamp from being adversely affected by heat and vapors such as water and oil, and the structure and assembly can be simplified.
In addition, it is possible to prevent adverse effects caused by heat conduction to the illumination lamp.
