Description

Detailed Description of the Invention 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a cooking appliance, such as an electric rice cooker, which has an operation display panel on the outside of the main body.

BACKGROUND OF THE INVENTION Conventionally, this type of cooking utensil has been developed, for example, by
It had a structure as shown in Publication No. 119.

That is, as shown in FIG.
It has a double structure, with a heat insulating material 4 interposed between the body 2 and the inner frame 3. Further, 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 portions of the body 2 and the side portions of the inner frame 3 is uniform.

The operation display board 6 is provided on the side surface of the main body 1. Specifically, the upper claw 6a of the operation display board 6 is inserted into the fixing hole 2a of the body 2, and the lower part of the operation display board 6 is fixed. It has generally been fixed to the lower surface of the lower frame 7 or the side surface of the lower frame 7, or to the body alone or across the body and the lower frame, and the operation board 8 is disposed inside the operation display panel 6.

Problems to be Solved by the Invention In such a conventional configuration, the display portion of the operation display board 6 is easily concentrated in the lower part of the main body, but problems arise such as difficulty in operability and visual visibility. .

For this reason, the display panel is elongated to the top of the main body, and a large operation display panel 6 is required even though the operating section and display section themselves are small. Therefore, it is unsightly in appearance and requires a large display board that is not necessary for functionality. Also, since the fixing positions are separated vertically, it is necessary to use a box-shaped strong display board, and it is necessary to use a strong box-like display board, or to install the main unit in the opposite direction. There was a problem that required installation and assembly.

In addition, switches, a liquid crystal display, and 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. There are problems such as the large storage space required for the products.

Means for Solving the Problem In order to solve this problem, the present invention has a cylindrical double structure in which the thickness of the internal heat insulating layer of the main body is non-uniform, and the cylindrical double structure constitutes the upper part of the main body. An upper frame connecting the upper part of the layered structure is provided, an operation display board is provided from the upper surface of the upper frame to the side surface of the body of the double structure outer frame, and the cylindrical double structure portion where the operation display board is located is connected to the heat insulating layer. The structure is selected depending on the thickness.

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. It is also possible to eliminate protrusion by narrowing the difference in the thickness of the heat insulating layer.

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 possible to use a material with relatively high strength among synthetic resin materials. This is common, and since the operation display board is fixed to both the high-strength upper frame and body parts, reliable fixation with little distortion is possible.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.

In FIGS. 1 and 3, 10 indicates a body 11 and a protective frame 1.
2, the main body has a cylindrical double groove structure, and a heat insulating layer 13 is formed between the body 11 and the protective frame 12. A heat insulating layer 13a at the rear of the product and a heat insulating layer 13b at the front of the product
is non-uniform and the thickness is 13a<13b.

The operation display board 14 is located in the thicker part 13b of the heat insulating layer 13, and the mounting position of the operation board 15 mounted inside the operation display board 14 is placed in the thicker heat insulating layer 13b inside the body 11. , therefore the operation display board 1
4 does not protrude to the outside of the body 11.

An annular upper frame 16 is combined at the upper part of the body 11 and the protection frame 12, which form the cylindrical double structure, to connect them. The upper frame 16 is formed so as to extend from the upper frame upper surface part 16a to the body side part 11a of the body 11 of the cylindrical double structure outer frame, and the operation display plate 14 is disposed on the body 11 with its engaging claws 14a.
The upper part of the operation display board 14 is fixed to the upper frame 16 from above with fixing screws 17.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the thickness of the heat insulating layer of the cylindrical double structure in the main body is made uneven, the operation display board is located in the thick part, and the cylindrical By attaching the operation display board from the top surface of the upper frame of the double structure upper part to the side surface of the body, the amount of protrusion of the operation display board from the side surface of the body can be reduced, resulting in a smooth appearance. The upper frame is integrally formed with the hooks necessary for attaching the outer cover covering the upper part of the main body and for opening and closing operations.
It is a part that requires strength and dimensional accuracy, and has excellent mounting position accuracy and mounting strength. It is also effective for mounting the operation display board, and the product can be turned in the opposite direction when assembling the operation display board. There is no need to do this, and work efficiency can be improved by simply removing the fixing screws on the top of the upper frame.

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 unnecessarily large operation display board. It has good operability and can be made compact.
