Description

Electric stove {ELECTRIC STOVE}

The present invention relates to an electric stove, and more particularly, the hemispherical reflector is rotated in a state where the main body is fixed to adjust the radiation angle, the electric safety device equipped with a thermal sensor, conduction switch, and safety distance sensor as a safety device It's about the stove.

In general, an electric stove is provided with a heating wire or a heating lamp as a heating means, and the heat energy radiated from the heating wire or the heating lamp is reflected on the reflector to heat a predetermined space.

Electric stoves such as these are often fixed in the body and heat energy is transmitted only in one direction. Accordingly, there was a problem that the heating space is extremely narrow.

Accordingly, in order to solve this problem in recent years, an electric stove has been developed in which the body is rotated.

That is, as shown in FIG. 1, the conventional electric stove is a fixed member 1 located at the bottom, a rotary shaft 2 rotated by a motor (not shown) embedded in the fixed member 1, and a rotary shaft ( And a heat generating means composed of a main body 3 bound to 2) and a ceramic tubular body 5 in which the heating wire 4 is wound.

Therefore, when the power is applied, the rotating shaft 2 is rotated, and thus the main body 3 is rotated, and the thermal energy radiated from the heat generating means inherent in the main body 3 heats the predetermined space.

However, such a conventional electric stove had the following problems.

In other words, there is a problem that the main body is supported only by the rotating shaft and extremely weak in durability.

In addition, since the body is supported by the rotating shaft while being rotated, vibration or noise occurs, and there is a problem in that a motor having a larger torque must be used to rotate the body itself.

In addition, a predetermined space must be secured by rotating the main body, and accordingly, there are many difficulties in installing and using an electric stove in a narrow space.

The present invention has been made to solve the above problems, the object of the present invention is to provide an electric stove that can be more durable by improving the rotating structure to expand the heating space.

Another object of the present invention is to provide an electric stove that allows the reflector to be rotated without rotating the main body, thereby reducing the load of the motor according to the rotation and thus reducing the shaking and noise.

Another object of the present invention is to provide an electric stove that can be easily used in a narrow space by reducing the copper wire caused by the rotation.
