Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a door body attached to a roasting device such as a toaster oven.

An embodiment of the present invention will be explained below with reference to the drawings. Reference numeral 1 denotes a box-shaped roaster body, and roasting heaters (not shown) are installed in the upper and lower parts of the roasting chamber 2, respectively. A shelf member 3 on which objects to be roasted are placed is stretched over the section.

Reference numeral 4 denotes a door body, which is pivoted on both sides of the lower side so that the front opening of the roasting chamber 2 can be opened and closed, and can be opened and closed by holding a handle body 5 provided on the upper side.

The door body 4 is composed of a front plate 6, a back plate 7, and a glass plate 8 interposed between these front and back plates.
The surface plate 6 has a window hole 9 formed approximately in the center, and the four sides of the outer periphery are bent slightly rearward to form peripheral walls 10, 10, 10.10.
At the same time, retaining portions 11.11 projecting slightly inward are integrally formed at appropriate positions on the two opposing sides of the peripheral wall.

The back plate 7 has a similar shape to the front plate 6, and has a window hole 9' in the center, and the four sides of the outer periphery are bent slightly forward to form the peripheral wall 10 of the front plate 6. 10,10.
Peripheral wall 12, 12, 12.1 located along the inside of 10
Engagement portions 11, 1 formed integrally with the peripheral walls 10, 10 of the surface plate 6 are formed on the peripheral walls of the two opposing sides.
It forms a locking part 13.13 which engages with 1.

In the central part of the peripheral walls 12, 12 on the two opposing sides of the bunker, there is a protruding piece 17, 17 whose height dimension of the peripheral wall is slightly larger than the other parts.
It is formed as an extension.

A window (L9') is provided with support pieces 14, 14, 14 for holding the glass plate 8 in the outline of the window (L9').
．． 14 are formed, the glass plate 8 is held within the support pieces and each corner portion 15, 15 of said glass plate 8 is formed.
, 15.15 are each corner raised portion 16 of the window hole 9',
16, 16, and 16, so that the glass plate 8 is fixed at a desired position when it is sandwiched between the front and back plates 6, 7.

When assembling the door body 4 with the front plate 6, glass plate 8, and back plate 7 in such a configuration, first, the window hole 9 of the front plate 6 is opened.
A glass plate 8 is temporarily installed corresponding to the
The surrounding walls 10, 10, 1 are superimposed on the surface plate 6.
The peripheral wall 12, 12゜12.12 is installed inside the 0.10, and after confirming that the glass plate 8 is located within the window hole 9' of the back plate 7, the back plate 7 is placed on the front plate 6 side. When pressed, the protruding pieces 17.1 formed to extend on the peripheral walls 12, 12 of the back plate 7
7 comes into contact with the rear wall 18 of the front plate 6.

When pressed further, the back plate 7 bends around the protrusion piece 17, and the locking parts 13, 13 of the peripheral walls 12, 12 formed on both sides become the engaging parts 11, 11 formed in the peripheral walls 10, 10 of the front plate 6.
engage and lock.

That is, the front plate 6 and the back plate 7 form gaps S and S on both sides of the protruding pieces 17 and 17 (see Fig. 2), and are firmly and reliably locked together by the springback action. This is to maintain the following.

In order to attach the handle body 5 to the upper side of the door body 4, a handle attachment hole (not shown) is provided at the center of the upper side of the surface plate 6.
Correspondingly, screws 19 are inserted from the rear wall 18 side.
The handle body 5 is fixed by screwing into the handle body 5.

As mentioned above, the door device of the roaster according to the present invention is a roaster in which the door has a transparent glass plate at the front opening of the roasting chamber and can be opened and closed freely. A surface plate having a plurality of engaging portions at appropriate positions on the two opposing sides of the peripheral wall, and a glass plate is interposed between the surface plate and the peripheral wall. A window hole is similarly drilled approximately in the center for overlapping, and four sides of the outer periphery are bent forward to form a peripheral wall located inside the peripheral wall. The door body is assembled by forming a locking part that engages with the retaining part, and a back plate having a protruding piece formed in the center of the two remaining sides of the peripheral wall to abut against the back wall of the face plate. The present invention provides a practical door device that does not use tightening parts such as screws, requires fewer parts, and accordingly requires fewer assembly steps, and is suitable for mass production.
