DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A representative embodiment of the present invention will be described below in detail with reference to FIGS.

As shown in FIGS. 1, 2, 4 and 5, this embodiment employs an electric heating cooking apparatus in which a shallow pan-shaped cooking plate 1 and a heater 2 for heating the same are accommodated in a protective case 3. This figure shows a case of an electric heating cooker, which is a so-called hot plate, having a power supply control device 4 for connecting a heater to a power supply and controlling the temperature. However, the present invention is applicable to any electric heating cooker satisfying such a basic configuration.

For example, another similar commercially available electric pot uses a pot deeper than the cooking pan 1.

A cooking plate 1 for a hot plate according to the present embodiment.
Is made of a metal, for example, an aluminum-based metal having a surface coated with a fluorine resin layer or a sprayed titanium layer is preferable. However, depending on the durability and the type of cooking, it is possible to adopt a material or an appropriate material and structure.

The protective case 3 is a molded product made of a synthetic resin, which is advantageous for weight reduction and cost reduction, but is not particularly limited to such. The protection case 3 of the present embodiment is a shallow container type that covers the outer periphery of the bottom side of the bottom of the cooking pan 1 in accordance with the pan 1 of the cooking pan 1 of the present embodiment. This prevents people and surroundings from coming into direct contact with the cooking board 1 being heated, thereby protecting the surroundings. The protective case 3 has legs 3d projecting below the bottom thereof, as shown in FIGS.
As shown in (1), the protective case 3 is provided integrally or separately, to prevent the bottom of the protective case 3 from directly contacting a mounting surface such as a table. Leg 3 like this
The structure and the method of providing d are free.

The protective case 3 has a metal heat shield plate 5 attached to the inside thereof. Heat from the heater 2 and the cooking plate 1 heated by the heater 2 directly reaches the protective case 3 to support the heat deterioration and burnout. And the heat shield plate 5, the bottom of the protective case 3, and the legs 3d make it difficult for the heat of the cooking plate 1 and the heater 2 to reach the mounting surface more than the bottom of the protective case 3. I have. Thereby, depending on the state of the mounting surface, it is possible to cope with the case where the mounting surface is weak to heat.

As shown in FIGS. 4 and 5, a heat shield plate 5 made of perforated stainless steel having a hole and a synthetic resin or ceramics are provided on the bottom of the protective case 3 at the bottom thereof. It is attached with screws 8 and 9 via a heat shield block 7 made of a heat insulating material such as.

The bottom of the heat shield plate 5 and the heat shield block 7 are fastened by screws 8 through the heat cylinder 6. As a result, the heat of the heat shield plate 5, the heat shield cylinder 6, and the screws 8 thermally conducted from the heat shield plate 5 does not directly reach the protective case 3, and the heat shield plate 5 is made of metal. This prevents the heat of the heat shield plate 5 from adversely affecting the protective case 3 due to the mounting structure using the mounting member of the above. Further, the mounting structure of the heat shield plate 5 is deteriorated or burned by the heat. Can be prevented.

In this embodiment, the heater 2 is connected to the protective case 3

The cooking board 1 is mounted on the heater 2 provided with the above wiring pattern, with its own flat bottom bottom surface mounted and supported at a predetermined height in the protective case 3, and the bottom is heated by the heater 2. Then, heat cooking is performed on the bottom upper surface. Various types of cooking such as okonomiyaki, hot cakes, grilled meat, and stir-fried vegetables can be prepared by heating. For grilled meat, it should have the right half of FIGS. 1 and 4 and the unevenness 1e as shown in FIG. However, in other cases, the flat surface 1f as shown in the left half of FIGS. 1 and 4 is preferable. However, any shape, such as providing a hole with a hole, may be used according to the content of cooking.

Positioning ribs 5b are provided on each part of the peripheral wall 5a of the heat shield plate 5 in the circumferential direction, and the peripheral wall 1a of the cooking board 1 fitted on the heat shield plate 5 and placed on the heater 2 abuts on each other. Thereby, the cooking board 1 is correctly positioned on the heater 2. By this positioning, the cooking plate 1 can receive the heating by the heater 2 without bias, and the cooking plate 1 is biased in the heat shield plate 5 and directly contacts the peripheral wall 5a of the heat shield plate 5 to form a heat shield. Since the heat is not directly transmitted to the plate 5, it is easy to use.

The cooking board 1 has a substantially rectangular plane shape having corners 1b which are rounded in the diagonal direction, and the protective case 3 and the heat shield plate 5 also have similar shapes corresponding thereto.

Even if the power cord 23 is connected to this, it does not hinder any person located so as to correspond to each side of the protective case 3 avoiding the corner 3c. In addition, it is easy for a person on either side located on both sides of the corner 3c where the energization control device 4 is located to operate. Therefore, usability is improved. The operation of the power supply controller 4 is performed by inserting itself into the power supply controller mounting port 22 to connect and disconnect the connection terminal 26 of the heater 2 and to rotate the operation dial 29 in the connected state. The temperature is controlled in the off state and the on state. The on / off operation and the temperature adjustment operation can be performed by a slide.

In the case of the present embodiment, the energization control device mounting port 22 is formed by a member different from the protective case 3 as shown in FIG. 2, but it can also be formed integrally with the protective case 3. It is preferable that the connection terminal 26 is fixed so as to protrude into the insertion hole 22a of the power supply control tool 4. However, the power supply control tool 4 has a little play with respect to the insertion hole 22a, and the fitting of the both is performed. It is preferable that the connection between the energization control device 4 and the connection terminal 26 is not hindered by the tight fit.

Further, as described above, the cooking board 1 and the protective case 3 have handles 13 and 16 which protrude outward, for example, on both short sides opposite to each other when viewed from a plane. As shown in FIG. 1, the handle 1 is separated from the corners 1b and 3c where the power supply control device 4 is provided.
When the cooking panel 1 and the protective case 3 are gripped by the components 3 and 16, and the cooking panel 1 is used alone or the entire hot plate is handled, the power supply control tool 4 does not interfere and is easy to handle.

Furthermore, as shown in FIGS. 1 and 2, the power supply control device 4 is located in a portion of the cooking panel 1 and the protective case 3 where the handles 13 and 16 are not provided, so that the control devices 4 are not obstructed by the handles 13 and 16.
