Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is adapted to the structure of a lid for a cooking utensil used in general households.

BACKGROUND OF THE INVENTION A conventional cooking device of this type is, for example, the Japanese Utility Model Publication No. 59-4176.
As shown in Publication No. 1@, the structure was as shown in FIGS. 3 and 4.

In the figure, 1 is a cooking utensil main body, 2 is a lid that is rotatably supported on one side of the top opening of the cooking utensil main body 1 and covers the top opening, and 3 is an upper lid that forms the top surface of the lid 2. , 4 is a resin ring-shaped lid frame fixed to the outer periphery of the lower surface of the lid 2, 5 is a lower lid forming the lower surface of the lid 2, 6 is provided in the internal space of the upper lid 3 and the lower lid 5, A lid surface heating material 7 made of glass wool for increasing the thermal efficiency of the cooker is a reinforcing metal fitting with a cross-section shape fixed to the lid frame 4 with screws 8. The reinforcing metal fitting 7 is arranged at right angles to the direction in which the shaft 9 and the hook lever 10 are connected, and prevents deformation of the lid 3 in the direction in which the reinforcing metal fitting 7 is located.

Problems to be Solved by the Invention However, in the conventional configuration described above, the reinforcing metal fitting 7 and the M heat insulating material 6 are constructed as separate parts, so the number of parts is large and the workability is poor. Moreover, glass wool, which is resistant to heat, is generally used as the lid insulation shrine 6, but this glass wool has many problems, such as the dust generated from it being harmful to humans.

Furthermore, since glass wool requires a certain amount of air space in order to obtain a heat insulating effect, the lid body 2 also requires a large space, and a considerable space is also required to accommodate the heat insulating material.

The present invention solves the above-mentioned conventional problems, and aims to provide a lid that increases the thermal efficiency of a cooking utensil without using a heat insulating material such as glass wool, and that causes extremely little deformation of the lid.

Means for Solving the Problem In order to solve this problem, the present invention includes a side wall cylindrical lid surface heating section that divides the internal space of the lid body to increase the thermal efficiency of the cooking utensil, and prevents deformation of the lid body. The deformation prevention fitting is formed as an integral sheet metal structure.

Function According to this configuration, since the lid heating material is in the form of a sheet metal, there is no need for a large air layer in the interior space of the lid, and the interior space of the lid is divided into two by the sheet metal shaped lid heating portion having a cylindrical side wall. The double air layer increases the heat insulation effect. Moreover, since no insulating material such as glass wool is used, problems such as dust are eliminated, and workability is improved.In addition, the deformation prevention metal fittings that prevent deformation of the container body and the lid surface heating material are integrated into a falling plate. Since the lid plate and the lower lid are fixed to the lid frame using the same screw, the number of parts and work steps are also reduced.

EXAMPLE Hereinafter, an example of the present invention will be described in detail based on FIGS. 1 and 2.

In the figure, 11 is the main body of the cooking utensil, 12 is a body 73 that is rotatably supported on one side of the top opening of the cooking utensil main body 11 and covers the top opening, and 13 is made of resin that forms the top surface of the lid 12. The upper lid 14 is a resin ring-shaped lid frame fixed to the outer periphery of the lower surface of the lid 12, and 15 is a lower lid constituting the lower surface of the lid 12.

16 is an internal space 1 formed between the upper lid 13 and the lower lid 15.
7, and is attached to the lid frame 1 together with the lower lid 15 by screws 18.
4 is a sheet metal-like lid plate that is integrally fixed to 4. The lid plate 16 has a deformation preventing portion 21 which has a cross-section shape and is arranged perpendicularly to the direction in which the shaft 19 and the hook lever 20 are connected.
and a sheet metal-like lid surface heating part 2 having a cylindrical side wall 22 on the outer periphery.
It is formed as an integral 474 structure consisting of 3 pieces.

The operation of the lid body 12 having the above configuration will be explained. Lid body 12
The lid surface heating part 23 of the lid body plate 16 provided in the internal space 17 of
Since it is shaped like a sheet metal, the space occupied by the lid surface heating section 23 is small. Therefore, the internal space 17 of the lid 12 is divided into two without requiring a large space inside the lid 12.

The lower air layer 24 formed by the lower lid 15 and the lid plate 16 forms a hermetic seal through the lid frame 14 by the cylindrical side wall 22, and does not come into contact with the upper lid 13, which is an outer shell part. A lid body 16 having such a lower air layer 24
The upper air layer 25 formed by the upper lid 13 and the lid body plate 16 enhances the heat insulation effect by a double air layer.

The cylindrical side wall 22 also has the effect of increasing the strength of the lid plate 16 itself.

Furthermore, the deformation prevention portion 21 of the lid body plate 16 has a cross-sectional shape,
Since it is provided perpendicularly to the direction in which the shaft 19 and the hook lever 20 are connected, the deformation of the lid body 12 is extremely small in the direction in which the deformation prevention part 21 is located.

Effects of the Invention As described above, according to the present invention, a lid plate having an integral structure of a lid heating part and a deformation preventing part is installed inside the lid, and a cylindrical outer wall is attached to the sheet metal lid heating part. This not only increases the strength of the lid plate, but also allows the vessel to be separated into two sealed air spaces, making it possible to obtain a compact and highly insulating effect.

Further, according to the present invention, the lid body will not be deformed due to the deformation preventing portion integrated with the lid body plate due to the heat generated during cooking or the pressure inside the steel.

Moreover, since the present invention does not use a heat insulating material such as glass wool, problems such as dust are eliminated, and workability is improved. In addition, the lid surface heating part and the deformation prevention part are integrated, and the lower lid and the lid frame are By fixing the cover plate and the cover plate with the same screw, it is possible to reduce the number of parts and the number of work steps, which has great practical value.
