Description

[Detailed Description of the Invention] Field of the Invention The present invention relates to an inner casing structure of a cooking device such as a toaster oven, and particularly to a mounting structure for a reflector forming the ceiling surface of the inner casing.

Conventional technology and its problems Conventionally, for example, there is a toaster oven whose casing has a double wall structure of an outer casing and an inner casing, and a single reflector plate is attached to the back and ceiling of the inner casing. It is known from Utility Model Publication No. 55-49688. In this type of toaster oven, the above-mentioned reflector is equipped with a
Special heat-resistant plates such as Ulster steel plates are used, but this type of heat-resistant plate is more expensive than ordinary galvanized iron plates, etc., so it is necessary to make it as small as possible, and therefore only the most expensive ceiling surface is heat-resistant. It is conceivable to use a galvanized iron plate for the back side.

However, when the reflector is divided into the back part and the ceiling part as described above, the number of joints increases accordingly.
Not only is it time-consuming to assemble, but there are also gaps between the joints, which reduces the sealing performance of the inner casing and reduces heating efficiency. Also,
Since the door is in contact with the front of the inner casing, the front of the side plate of the inner casing and the front of the reflector must be accurately positioned. The position was determined by fixing or welding.

Purpose of the invention The present invention was devised in view of such conventional problems, and its purpose is to easily attach the reflector that makes up the ceiling surface of the inner casing to the side panel without any gaps, and to An object of the present invention is to provide an inner casing structure of a cooking appliance in which the front part of a reflector can be accurately positioned.

Structure of the invention In order to achieve the above object, the invention consists of side plates on the left and right sides of the inner casing and a rear plate on the rear side, and both sides of the reflector are attached to the top surface of the side plates. Place the protrusion on the side plate, insert the projecting piece that stands up from the side plate into the insertion hole of the reflector, bend it to fix the reflector, and insert the front side of the reflector into the insertion groove provided at the upper end of the front part of the side plate. By inserting the insertion grooves on both sides of the part, the front part of the side plate and the reflecting plate are positioned.

DESCRIPTION OF EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 and 2 show a toaster oven as an example of the cooking device according to the present invention, and 1 is an outer casing;
Reference numeral 2 denotes an inner casing. The front surfaces of the outer casing and the inner casing are open, and a door 3 for opening and closing these openings is provided to be rotatable about the lower end thereof. Inside the inner casing 2, two heaters 4 (see FIG. 3) are provided above and below, and a grill 5 that moves forward and backward in conjunction with the door 3 is provided in the middle.

As shown in FIG. 3, the inner casing 2 has left and right side panels 6 and a back panel 11 made of a single plate, and a reflector plate 12 made of a heat-resistant plate such as Ulster steel plate is attached to the ceiling surface. ing. That is, a mounting piece 7 is bent outward at the upper end of the side plate 6, and a projecting piece 8 that stands upward is provided in the center of the mounting piece 7. Further, a collar piece 9 is bent outward on the front surface of the side plate 6, and a fourth
As shown in the figure, an insertion groove 10 is formed. The upper and lower parts of the back plate 11 are inclined forward, and both edges of the upper and lower parts are fixed to the side plate 6 by caulking.

On the other hand, the reflection plate 12 has its front part tilted downward and stands up upward, and has this upright piece 13 as a contact surface against which the inner surface of the upper end of the door 3 comes into contact. A claw piece 14 having an insertion groove 15 is formed. Slit-shaped insertion holes 17 are provided on both sides of the central flat portion 16 of the reflecting plate 12, and hanging pieces 18 are formed at both ends of the flat portion 16 to hang downward. Further, a lug 19 is formed at the rear end of the flat portion 16 and comes into contact with the outer surface of the upper end of the back plate 11 .

Next, a method of attaching the reflecting plate 12 to the inner casing 2 having the above structure will be explained. First, when the reflecting plate 12 is placed on the side plate 6, the insertion hole 1 of the reflecting plate 12
The projecting piece 8 of the side plate 6 is fitted into the 7, the hanging piece 18 is engaged with the outside of the mounting piece 7, and the ear piece 19 is fitted on the back plate 11.
Abuts against the outer surface of the upper end. Then, the insertion groove 15 of the reflection plate 12 is inserted into the insertion groove 10 of the side plate 6,
The front surface of the reflection plate 12 and the front surface of the side plate 6 are accurately positioned flush. After that, by bending the projecting piece 8 inward, the reflecting plate 12 is attached to the side plate 6.
and is fixed in close contact with the upper surface of the back plate 11,
The inner casing 2 can be sealed tightly.

Effects of the invention As described above, the present invention combines the inner casing with a reflector,
Consisting of both side plates and a back plate made of a single plate,
After placing the reflector on the side panels and back panel, the reflector can be fixed by simply bending the protruding pieces, which reduces assembly time and speeds up the work. The casing can be assembled without any gaps, without compromising sealing performance. Furthermore, the engagement between the insertion grooves enables accurate positioning of the front surface of the side plate of the inner casing and the reflecting plate, so that the contact surface with the door does not become distorted. Furthermore, since the expensive reflector is separate from other inner casing constituent materials, the material can be freely selected, and the reflector can be made inexpensive as a whole.
