Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention particularly relates to a cooking appliance with an improved door structure.

[Conventional technology]

FIG. 4 is a partial cross-sectional view of a door in a conventional cooking device, which has a window portion 24b with a large number of through holes 24a in the center, and a surrounding frame portion 25 bent to have a substantially U-shaped cross section at the periphery. A cover material 23b is provided on the outer surface of the surrounding frame portion 25 in the door body 24 having
The York dielectric part 29 and the radio wave absorber part 30 are provided on substantially the same plane as the window part 24b of the door body 24 in a manner that seals the recess of the surrounding frame part 25.

A translucent panel 26 is superimposed on the inner surface of the window portion 24b of the door body 24, and its peripheral edge is fitted into a groove 27 formed along the inner edge of the York base plate portion 28 using packing 27a. It is fixed together.

[Problems to be solved by the invention] By the way, in the conventional door as described above, since the translucent panel 26 is fixed using the packing 27a, there is no groove 27 in which the packing 27a is fitted. The structure of the door body 24 becomes complicated, and there are problems such as poor workability during assembly.

[Means for solving problems]

The present invention was developed in view of the above circumstances, and its purpose is to fix the peripheral edge of the translucent panel within the seat formed on the peripheral edge of the door body using adhesive. To provide a cooker which has excellent assembly workability and which also has a simplified structure of the door itself, thereby reducing the cost of the product.

The cooking appliance according to the present invention is equipped with a door formed by fixing a panel to a window formed in the center of the door body, and the cooking appliance has a through hole in the periphery of the door body for allowing adhesive to penetrate into the wall surface. The present invention is characterized in that a catch seat is formed, and the peripheral edge of the panel is fixed to the catch seat using an adhesive.

〔Example〕

The present invention will be specifically explained below based on drawings showing embodiments thereof.

Fig. 1 is a perspective view of a cooking device according to the present invention (hereinafter referred to as the proposed product), and Fig. 2 is a partially enlarged sectional view taken along the - line in Fig. 1, where 1 is a cooking chamber and 2 is an upper wall thereof. , 3 indicates a door.

The door 3 is composed of a door main body 4, a surrounding frame 5 formed around the door, a translucent panel 6, etc. The lower part of the surrounding frame 5 is pivoted to the lower peripheral wall of the cooking chamber 1, and the upper part is pivoted to the lower peripheral wall of the cooking chamber 1. A handle 3a for opening and closing is provided on the peripheral wall.

The door body 4 has a window 4b with a large number of small through holes 4a in its center, and a catch 7 on the periphery for fixing the peripheral edge of the translucent panel 6, and a catch 7 on the outside of the catch 7. A yoke substrate portion 8 is formed.

When the door 3 is closed, the cooking chamber 1
It has a flat surface that makes surface contact with the front surface of the surrounding wall.
Further, the catch seat 7 is formed to be located on the inner circumferential side of the York board part 8, and is formed to have an L-shaped cross section so as to face the circumferential surface and the outer peripheral surface of the translucent panel 6 with a slight gap therebetween. ing. The translucent panel 6 is made of a synthetic resin such as polypropylene and is formed into a rectangular plate shape, and is arranged so as to overlap the window part 4b from inside the window part 4b, and its peripheral part is positioned on the seat 7 and bonded with an adhesive material 7a. and is integrally fixed to the door body 4.

A small hole 7b is formed in the side surface of the catch seat 7 facing the surrounding frame portion 5, and when adhesive 7a is injected into the catch seat 7, a portion of the adhesive passes through the small hole 7b and connects to the York base plate portion 8. It is designed so that it enters the gap between the adhesive 7a and the surrounding frame 5, solidifies as it is, and improves the bonding between the adhesive 7a and the seat 7.

Note that the shape, size, number, etc. of the small holes 7b are not particularly limited and may be appropriately selected as required.

The surrounding frame portion 5 is a frame material having a U-shaped cross section and is formed into a rectangular ring shape along the peripheral edge of the door body 4, and its inner edge is fixed so as to follow the periphery of the window portion 4b of the door body 4. Furthermore, a chiyoke dielectric part 9 and a radio wave absorber part 10 are disposed between the outer edge and the outside edge of the chiyoke substrate part 8 in such a manner as to seal them.

The shapes of the surrounding frame portion 5, the yoke substrate portion 8, the yoke dielectric portion 9, and the radio wave absorber portion 10 themselves are substantially the same as the conventional structure shown in FIG.

In the case of the above-mentioned product, since the peripheral edge of the translucent panel 6 is adhesively fixed to the seat 7 with the adhesive 7a, the adhesive fixation of the translucent panel 6 Can be easily assembled,
Workability is good, and the translucent panel 6 can be made substantially flush with the York board 8, and the inner surface of the door 3 can be flattened, resulting in a high design effect. Further, since a small hole 7b is bored in the wall surface of the seat 7, the adhesive 7a that enters the hole hardens, thereby providing a high bonding force between the seat 7 and the translucent panel 6.

〔effect〕

As described above, in the case of this product, the peripheral edge of the panel that is to be overlapped with the window with a large number of small holes provided in the center of the door body is placed inside the catch plate formed along the inner edge of the yoke base plate. Since we decided to use adhesive to fix it on the seat, it does not take up as much bulk as conventional packing, eliminates the formation of unnecessary gaps, and simplifies the overall structure. Since there are holes through which the adhesive can enter, some of the adhesive will seep out of the wall through these holes and solidify, improving the bonding of the panel to the seat and making it especially easy to assemble. The present invention has excellent effects, such as improved workability and reduced cost of the door itself.
