Description

[Detailed description of the invention] The present invention relates to the body structure of a cooking device such as an oven or toaster oven that has a substantially box shape, and includes an inner body having a cooking chamber,
The outer casing covering the inner body is assembled independently to facilitate the combination of the inner and outer casings, and to provide a casing structure that is strong and has good appearance quality.

Conventionally, as a similar example to the object of the present invention, there are pop-up toasters in which food is inserted into the cooking chamber from the top, but these have an open cooking chamber and the objects to be cooked are small. It was possible to relatively easily combine the inner and outer casings for the vessel.

Since the toaster oven and the like to which the present invention is directed have a relatively large body and a large opening/closing door for the cooking chamber, the outer plate, back plate, top plate, etc. are assembled in sequence on the inner body.

This method requires screw tightening to connect, requires more precision than necessary for each part, requires labor to change the moving direction of the heavy inner body many times, and is labor-intensive and expensive. It had the following disadvantages.

The present invention solves the drawbacks of the conventional cooking appliances mentioned above, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the main body of the toaster oven, which is separated from the inner body 2, outer casing 3, and legs 4 shown in FIG.

The inner body 2 has a substantially box shape, and has an inner plate 5 with four bent sides arranged on both sides, and a reflector plate 6 and a bottom plate 7 surrounding the back and top surfaces.
are fixed to each other to form a cooking chamber 8, and a door 10 having a window glass 9 is provided on the front surface so as to be openable and closable by a shaft 11.

Reference numeral 12 denotes a heat shield plate, which is fixed to the upper surface of the inner plate 5 with a screw 13 with a certain space between it and the upper surface of the reflector plate 6, and has a square convex stepped portion 14 in the center.

15 is a panel, and a heating element 16 provided in the cooking chamber 8.
Timer 17 and changeover switch 18 that control 16'
is attached to the front lower part of the inner plate 5.

19 is a power cord, which is connected to the bent part 3 on the lower surface of the inner plate 5.
It is attached by a cord stopper 20 held at 3.

21 is a grill provided in the cooking chamber 8, supported by a slit 22 provided in the inner plate 5, and linked to the opening and closing of the door 10 (
The interlocking mechanism (not shown) slides back and forth.

23 is a door handle.

The inner body 2 is formed with the above structure.

As shown in FIGS. 2 and 3, the outer casing 3 has a box-like shape with an open bottom and front surface, and has substantially square plate-shaped outer plates 24 on both sides, and a rear plate 25 with a substantially U-shaped cross section. Forming a letter-shaped body, the outer surface plate 2
4 are connected and connected by a substantially U-shaped connecting plate 26, and a rectangular retaining hole 27 is formed in the top surface.

28 is a tray having fixing claws 29 at the four corners, and the outer plate 2
4 is connected to the slit hole 30 provided on the outside 'M! ,
24 is fixed at a certain distance from the upper surface.

Reference numeral 31 denotes a handle for transportation, which is fixed to the side surface of the outer plate 24.

The outer casing 3 is formed with the above configuration.

Next, a method of assembling the inner casing 2 and outer casing 3 and detailed shapes related thereto will be explained.

As shown in FIG. 4, when the outer casing 3 is covered with the inner casing 2, the outer casing 3
The convex stepped portion 1 of the inner casing 2 is inserted into the retaining hole 27 provided in the upper part of the inner housing 2.
4 are engaged, and the top surface is positioned in the front, rear, left and right directions.

At the bottom of the main body 1, a mounting flange 32 provided on the lower end surface of the outer plate 24 and a bent portion 33 on the lower surface of the inner plate 5 are overlapped with each other, and the mounting holes 34 and 34' are screwed together with the legs 4.

Since the inner and outer casings 2 and 3 are combined as described above, the upper part of the main body 1 has a quadrilateral shape with the side plates 24, the back plate 25, and the connecting plate 26. By engaging the convex stepped portion 14 formed integrally with the outer casing 3, each member constituting the outer casing 3 comes into contact with it and forms a single plane, which increases the strength against parallelogram-like deformation. Become stronger.

Further, in the lower part, the mounting flange 32 and the bent portion 33 are simply overlapped and threadedly connected.

In this way, an integrated outer casing 3 with open front and bottom surfaces is completed separately for the inner casing 2, which integrates complex components.
Since the parts can be easily combined, there is less effort required to move the heavy inner casing 2, and the work becomes easier.

If vertical walls 35 and 36 are provided at the front of the reflecting plate 6 and the lower part of the connecting plate 26, respectively, and these are overlapped and screwed together, an even stronger combination can be obtained.

Figures 5 and 6 show a case in which the lower parts of the inner casing 2 and the outer casing 3 are engaged, there is no twisting deformation of the front surface of the container 1, and the assembly is easy. A fitting flange 7 is bent outward at the lower front surface of the outer plate 24 and protrudes outward, and the bent wall 38 provided on the panel 15 at the lower part of the inner housing 2 engages with the outer side as shown in FIG. The lower part of the outer plate 24 is regulated at a fixed position.

Reference numeral 39 denotes an inward locking wall provided above the fitting flange 37, which is integrally provided with the outer plate 24, and is a door mounting wall bent into a Z-shaped cross section on the front surface of the inner plate 5 of the inner casing 2. As shown in FIG. 6, the locking pawl 41 protruding from the locking claw 40 is fitted inside the locking wall 39, that is, inside the outer plate 24, and the door mounting wall 40 engages and abuts the outer side of the outer plate 24. Hold in place.

With these configurations, the front surface of the vessel body 1 has a parallelogram shape consisting of the outer plate 24, the connecting plate 26, and the panel 15, but the fitting flange 37 and the bending wall 38 engage with each other at a certain distance above the lower end of the outer plate 24. Since the outer plate contacts the integral quadrilateral of the mating panel 15 and its position is regulated, the strength against parallelogram-like deformation is increased.

Moreover, it is easy to hold it together as it does not require screws or the like.

Furthermore, when the locking wall 39 and the locking claw 41 are engaged, the outer plate 2
4 and the inner plate 5 are determined, the mounting holes 34 and 34' can be aligned, the screwing operation can be easily performed, and the deformation strength described above is further increased.

Note that 42 and 43 are ventilation holes. As described below, the present invention has the effect of making the assembly work easy, and has the effect of greatly reducing the number of joints and increasing the strength of the container body, and can provide an inexpensive product.

Furthermore, even when the tray is provided above the container, there is no need for any screws or the like for attachment to the outer surface, and the appearance quality is good.

Note that 42 and 43 are ventilation holes.
