Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking device with particularly good thermal efficiency or heat distribution for heating food.

Conventionally, heaters for heat-adjustable burial pots were made by fixing heating wires to an insulator, or by embedding heating wires in a flat or slightly curved heating plate. The thermal conductivity of the container varies greatly depending on the shape of the bottom surface of the container placed on the container, resulting in poor thermal efficiency. Even containers that initially have excellent flatness on the bottom often become deformed after long-term use or during cleaning, and even if a small foreign object gets caught during heating, the efficiency will be greatly reduced.

On the other hand, in terms of temperature distribution, for example, a flat heating element made by casting a sheathed heater into a metal casting may not cause any problems in normal cooking, but when cooking hot cakes, etc., where you want to brown evenly, the heating element must be placed close to the heating element. There was a drawback that the browning color changed in areas far away from each other.

The present invention aims to eliminate the conventional drawbacks and provide a cooking device that conforms to the shape of the bottom plate of the cooking device and has uniform temperature distribution and good thermal efficiency.

The present invention will be explained based on the drawings.

FIG. 1 shows a sectional view of the cooking device of the present invention.

In the figure, 1 is a dish-shaped hot plate, 2 is a powder with good thermal conductivity, such as iron sand or magnesium oxide, 3 is a sheathed heater, 4 is a nonflammable and heat-resistant thin film, and 5 is a heat-resistant thin film.
1 is a thermostat for controlling the temperature of the heater, 6 is a container plug, 7 is a power cord, 8 is a lamp filter, 9 is a lamp, 10 is a body, and 11 is a back plate.

The structure of the cooking device of the present invention will be explained.

The hot plate 1 has a plate shape, and a sheathed heater 3 is cast into the lower bottom part 1-1. The dish-shaped part is filled with a heat conductive member 2 and covered with a nonflammable and heat-resistant thin film 4 to prevent it from spilling.

Figure 2 shows a container 1 for cooking in the heating cooker of the present invention.
2 is shown.

FIG. 3 shows an electric circuit of the cooking device of the present invention, S is a power source, and 23 is a switch.

FIG. 2 is a diagram in which a container containing food to be cooked is placed on the heating cooker of the present invention. As can be understood from this figure, the powder covered with the thin film 4 changes its shape relatively freely depending on the shape of the bottom surface of the container and conforms to and adheres closely to the bottom surface of the container. As a result, the thermal efficiency of the heater makes it possible to evenly heat the contents in terms of heat distribution in the upstream container. Moreover, if the container is the same, even if there are slight changes in the bottom surface, it will adapt to the change and will always remain constant, making it easy to manage the cooking state by controlling the temperature of the heater.

As described above, the heating cooker of the present invention can be freely deformed by adapting to the shape of the bottom of the container placed on top like a powder with good thermal conductivity in the concave part of the hot plate in which the heater is embedded. At the same time, it is filled with a thermally conductive material that can maintain its shape, and the top surface is covered with a nonflammable, heat-resistant thin film to prevent the thermally conductive material from spilling, so it can be used as a container filled only with heat-resistant oil. When placed, the container will not adapt to the shape of the bottom and lack stability, causing uneven contact, and the container will always be placed in a stable state, and the bottom of the container and the thin film will be in close contact. become,
As a result, uniformity of heat distribution can be ensured, and thermal efficiency can be significantly improved.
