Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooking appliance, such as an electric rice cooker, that has an operation display board on the outside of the main body.

Conventional technology Conventionally, this type of cooking utensil was developed, for example, in the 1980s.
It had a structure as shown in Publication No. -91119.

That is, as shown in FIG. 4, the main body has a double structure consisting of a body 2 and an inner frame 3, and a heat insulating material 4 is interposed between the body 2 and the inner frame 3. Also,
The cylindrical centers of the body 2 and the inner frame 3 are the same, and the thickness 5 inside the double structure, that is, the distance between the side of the body 2 and the side of the inner frame is uniform.

The operation display section 6 is provided on the side surface of the main body 1. Specifically, the upper part of the operation display board 6 is fixed by inserting the claw 6a into the fixing hole 2a of the body 2, and the lower part of the operation display board 6 is fixed. Generally, it was fixed to the lower surface of the lower frame 7 or the side of the lower frame 7, or to the body alone or across the body and the lower frame, and the operation board 8 was arranged inside the operation display board 6. .

Problems to be Solved by the Invention In such a conventional configuration, the display portion of the operation display board 6 can be easily concentrated in the lower part of the main body, but problems such as difficulty in operability and visual visibility occur.
For this reason, the display panel is extended to the top of the main body, and a large operation display panel is required even though the operating section and display section themselves are small. Therefore, a large display board that is unsightly in appearance and unnecessary for functionality is required, and since the fixing positions are separated vertically, it is necessary to make it box-shaped and strong. There was a problem where I had to do the installation and assembly.
In addition, a switch, a liquid crystal display, and various other electronic components are attached to the operation board 8 housed inside the operation display board 6, and the operation display board 6 protrudes from the surface of the body to accommodate these. Therefore, there are problems such as increasing the storage space for the product.

Means for Solving the Problem In order to solve this problem, the present invention provides a cylindrical body, a cylindrical protection frame assembled inside the body, and a connection between the body and the upper end of the protection frame. The main body has a double structure with an annular upper frame,
The distance of the heat insulating layer between the body and the protective frame is made uneven, and a recess is formed at a middle position on the side of the body where the thickness of the heat insulating layer is large, and a recess is formed between the upper surface of the upper frame and the middle of the side of the body. The structure includes a concave portion and an operation display plate that covers the end of the body above the concave portion.

Function: With this configuration, part or all of the operation board inside the operation display panel can be housed in the heat insulating layer inside the body, and the amount of protrusion from the main body can be reduced. Furthermore, by increasing the difference in the thickness of the heat insulating layer, it is also possible to eliminate the protrusion.

Furthermore, since the operation section is located at the top of the main body, it is possible to place the operation display board close to the human eye during actual use, improving operability. Even if the operation display board is located in the position shown in FIG.

In addition, the upper frame that makes up the upper part of the main body has other functions such as the hinge part and hook part for fixing the outer lid, so it is recommended to use a material with relatively high strength among synthetic resin materials. This is common, as the operation display board is fixed to both the high-strength upper frame and the body, making it possible to securely fix it with little distortion.The body also has a recess at the middle position on the side so that it can be fixed at both ends. Since the locking portion with other parts is connected in an annular shape, the shape is stable, and the locking force and position of the locking relationship between the parts in the locked state are also stable, increasing the strength.

Examples Examples of the present invention will be described below in Figures 1 to 3.
This will be explained with reference to the figures.

In Figures 1 and 2, 10 is the body 1.
The main body has a cylindrical double structure consisting of a body 11 and a protective frame 12, and a heat insulating layer 14 is formed between the body 11 and the protective frame 12. The thickness of the heat insulating layer 14a at the front of the product and the heat insulating layer 14b at the rear of the product are made non-uniform so that the thickness is larger at the front and smaller at the rear. A recess 11a is provided in the middle position of the side of the body 11, and the upper end is a curling part 1 with the outer shape remaining.
1b. The body 11 and the protection frame 12 are connected at their upper ends by an upper frame 13.

Reference numeral 15 denotes an operation display board, whose lower part is locked to the body 11 by an engaging claw 15a, and whose upper part is an upper surface part 13a of the upper frame 13 that constitutes the upper surface of the main body 10 having a double structure.
It is fixed from above with fixing screws 16, and an operation board 17 provided inside the operation display board 15 and an insulating cover 18 covering the inside thereof are provided at a position corresponding to the recess 11a on the side surface of the body. It is formed so as to also cover the curling part 11b above the recessed part 11a of the body.

FIG. 3 shows a state in which the operation display board 15 has been removed, and a recess 1 provided at an intermediate position on the side of 11 is shown.
1a is provided at an intermediate position of the body leaving at least the curling part 11b at the upper end of the body, so that the notch 19 formed in the recess 11a of the body 11
Even if there is, when the upper frame 13 is press-fitted and fixed by force fitting, the outer shape of the body 11 will not protrude from the outer shape of the upper frame 13 and the fixing will become unstable, and the inner diameter of the upper end of the body It is securely fixed due to the firmness of the outer diameter of the upper frame.

In addition, the size 20 of the operation display board 15 and the recess on the side surface of the body are determined depending on the size of the operation board and the insulating cover 18 that are attached to the inside of the operation display board 15 while the operation display board 15 is positioned on the upper side of the main body 10. By changing the height 21 up to the height 21, the size of the operation display board 15 can be set depending on the height 21 with a minimum space.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, there is provided a cylindrical body with a recessed portion at an intermediate position on the side, and a heat insulating layer on the inner side of the body having an uneven distance from the body. The main body has a double structure, consisting of a cylindrical protective frame provided so that the thickness of the heat insulating layer becomes thicker at the recess position, and an annular upper frame that engages these at the upper end. By providing a recess provided in the middle of the side and an operation display board that covers the end of the body above the recess, the operation board provided inside the operation display board can be provided at a position corresponding to the recess on the side of the body, making it possible to It can be embedded in the heat insulating layer inside the main body of a heavy structure, and the amount of protrusion of the operation display board from the body surface can be reduced, improving the appearance. In addition, the main body has a double-layer structure, and by locking the body with a recess and the upper frame while leaving the body end, the shape of the locking part is stabilized, and the locking force in the assembled state is increased. Since the position can be stabilized, a similar effect can be brought about in fixing the operation display board fixed to these, and the strength of the product can be increased.

In addition, regarding the fixing method, there is an operation display board from the top of the upper frame to the side of the body, an engaging claw on the side of the body, and a fixing screw on the upper frame from the top of the upper frame, so there is no need to turn the product in the opposite direction. When removing it, you can simply remove the fixing screw and the work efficiency will be improved.

In addition, since the operation display board is located at the top of the main unit, visibility and operability are improved, and the size of the operation display board can be set to match the operation board installed inside, eliminating the need for an unnecessary large operation display board. This makes it possible to make the device more compact.
