Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a hot plate type cooking device for use in general households.

BACKGROUND TECHNOLOGY A conventional cooker of this type was developed in the 1980s, for example.
As shown in Japanese Patent No. 35117, the structure was as shown in FIGS. 3 and 4. That is, the structure was such that a stepped portion 23 was provided on almost the entire circumference of the inner surface of the rising wall 22 of the hot plate 21, and the lid 24 was placed on this stepped portion 23.

Problems to be Solved by the Invention In such a conventional configuration, since the stepped portion 23 is provided almost all around the inner surface of the rising wall 22 of the heating plate 21, the inner periphery of the upper end of the rising wall 22 of the heating plate 21 The opening area at the inner periphery of the tip of the stepped portion 23 becomes smaller than the opening area of 23, the cross-sectional area of the rising wall 22 becomes larger, and as a result, if the opening area is the same, the heating plate becomes heavier than a hot plate without steps, which causes problems such as poor operability. It was hot.

This invention solves these problems,
The purpose is to provide a light and easy-to-use cooker that has a wide effective usable area.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a heating element, a substantially dish-shaped heating plate having a rising wall on the periphery, a lid placed on the heating plate, and a lid for heating the heating element. A guard is detachably attached to the plate and covers the bottom surface and surroundings of the hot plate, and step portions on which the lid is placed are formed at several locations on the inner surface of the rising wall of the hot plate,
Further, a gripping portion for the hot plate is formed on the stepped outer surface of the rising wall.

Effect With this configuration, when placing the lid, the lid can be placed stably by providing three or more stepped portions on the inner surface of the rising wall of the hot plate. The opening area is about 5% larger than that of a case with a stepped section provided almost all around the circumference, so the effective usable area becomes larger, and the weight of the hot plate can also be reduced, which improves usability. Furthermore, since a gripping portion of the hot plate is formed on the stepped outer surface of the rising wall of the hot plate, this serves as a grip when attaching and removing the hot plate from the guard, improving operability. .

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 1 is a substantially dish-shaped hot plate integrally formed with a heating element 2 by casting or the like.
This hot plate 1 has a rising wall 3, the surface of which is treated with a non-adhesive treatment. 4 is a lid placed on the hot plate 1; in order to place this lid 4,
Stepped portions 5 are formed at three locations on the inner surface of the rising wall 3 of the hot plate 1. A guard 6 is detachably attached to the hot plate 1 and covers the bottom and surrounding area of the hot plate 1. The guard 6 is made of plastic resin or the like. Further, in order to take out the hot plate 1 from the guard 6, a grip portion 7 is provided on the outer surface of the rising wall 3 on which the stepped portion 5 is provided. Reference numeral 8 denotes a power supply connection section attached to the end of the heating element 1, and this power supply connection section 8 is covered with a terminal cover 9. Reference numeral 10 denotes an automatic temperature regulator for controlling the temperature of the hot plate 1. The automatic temperature regulator 10 is connected to the power supply connection section 8 to control the energization of the heating element 1. Reference numeral 11 denotes a heat shield plate made of a zinc-treated steel plate, which is attached to the heat plate 1 with screws or the like.
Further, legs 12 made of thermosetting resin are attached to the heat shield plate 11 with screws or the like.

Further, the step portion 5 and the grip portions 7 provided on the outer surface of the step portion 5 are provided at positions facing the power supply connection portion 8 of the hot plate 1, and the other two locations are equally arranged on the hot plate 1.

In the above configuration, when the hot plate 1 is used with the hot plate 1 set on the guard 6, the reason for placing the lid 4 on the hot plate 1 is to quickly preheat the hot plate 1 before starting cooking, or The lid 4 is only used for steamed dishes such as gyoza, and is rarely used for general grilled dishes. Therefore, compared to the conventional structure in which a step is provided almost all around the circumference, the above-mentioned structure increases the effective usable area for cooking grilled dishes, and also reduces the need for a step for placing the lid 4. Since there are three parts, the lid 4 can be placed in a stable state. Moreover, since most of the rising wall 3 is straight, the weight can be reduced by that much compared to the part where the step part 5 is provided. Further, a grip portion 7 of the hot plate 1 is located outside the stepped portion 5.
, it is possible to easily take out the hot plate 1 from the guard 6, and therefore there is no need to separately provide a handle or the like on the hot plate 1. Furthermore, since one of the gripping parts 7 is provided on the opposite side of the power supply connection part 8, the hot plate 1 can be carried by holding the terminal cover 9 and the gripping part 7.

Effects of the invention As described above, according to the invention, since the stepped portions for placing the lid are provided at several locations on the inner surface of the rising wall of the hot plate, the effective usable area can be expanded. In addition, it has a sleek appearance, and the weight of the heating plate can be reduced, making it easier to carry and improving usability. Furthermore, since a gripping portion for the hot plate is formed on the stepped outer surface of the rising wall, this serves as a grip when attaching and detaching the hot plate from the guard, improving operability.
