Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric stove, and particularly to a device for changing the direction of reflection thereof.

BACKGROUND OF THE INVENTION A conventional variable reflection direction device for an electric stove has a structure as shown in FIGS. 6, 7, and 8, as shown in, for example, Japanese Patent Application Laid-open No. 149250/1983. .

That is, in the stove body 1, the reflector 2 and the heating element 3 fixed to the reflector 2 are integrated, and by rotating the knob 6 connected to the support shaft 6, the reflector 2 and the heat generator 3 are connected to each other through the support plate 4. The heating element 3 rotates together so that the direction of reflection can be changed to the recognition direction.

Problems to be Solved by the Invention However, in such a structure, the reflector 2 and the heating element 3
Since it is a large part, the structure is complicated and requires a lot of man-hours to assemble in order to maintain sufficient strength and rotate smoothly.

Therefore, the present invention is intended to automatically change the reflection direction with a simple structure.

Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
It is equipped with a stove main body with an open front, a heating element provided inside the stove main body, and a reflective plate provided on the back of the heating element, and columns surrounded by aluminum foil on the front of the heating element are parallel to each other. A reflector with a honeycomb-like reflective surface formed in the depth direction is rotatably supported on the stove body by a rotating shaft, and a rotary motor equipped with an eccentric cam is mounted inside the stove body. In addition, the eccentric cam and the reflector are connected to a crank.

For production The effect of this technical means is as follows.

That is, by rotating and tilting the reflector on the front surface of the heat generating element by a motor, the radiant heat of the heat generating element is reflected by the reflecting surface, refracted and emitted to the front.

The reflector is formed from a large number of fine reflective surfaces and is made of a highly reflective material, so it has good reflectivity and good refraction.

Furthermore, if the reflector is placed straight, the radiant heat of the heating element will not be reflected by the reflective surface and will not be refracted and will travel straight.

In other words, the direction in which the radiant heat is reflected can be changed by rotating only the reflector using the motor, without rotating the heating element and the reflector.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 1, 7 is a stove main body, 8 is a heating element, and a parabolic cross-section reflector 9 is attached to the back of the heating element 8 through upper and lower reflectors 10 to the stove main body 8. Fixed. Further, the heating element 8 is similarly fixed to the upper and lower reflecting plates 10, and is located approximately at the focal point of the parabolic shape of the reflecting plate 9, as shown in FIG.

The reflector 1 is placed on the entire opening of the reflector 9 in front of the heating element 8.
1 is located.

The reflector 11 is composed of a large number of honeycomb-shaped reflecting surfaces 12 in which hexagonal columns (columns) surrounded by foil are adjacent to each other as shown in FIG. It is made of a thin foil-like plate of about 100 ml.

Further, as shown in FIG. 5, the reflector 11 is fixed by a frame 13, and rotation shafts 14 are fixed at the top and bottom of the central part of the frame 13, and as shown in FIG. It is rotatably supported on a bearing.

Further, a motor 16 that rotates at approximately 5 rotations/minute is arranged on the upper surface of the upper and lower reflectors 10, an eccentric cam 18 is fixed to the rotation shaft 17 of the motor 16, and a crank 2 is attached to the other end 19 of the eccentric cam 18.
0 rotatably supported, and the other end of the crank 20 is provided at a position offset from the rotation shaft 14 in the left-right direction.
The reflector 11 is rotatably connected to the motor 16.
It rotates in the front-back direction by the rotation of.

Next, the operation of the structure of this embodiment will be explained. As shown in FIGS. 1 and 2, the radiant heat from the heating element 8 is reflected by the reflecting plate 9 and exits outward as parallel light rays.

When the reflector 11 is located parallel to the heating element 8 and the reflecting plate 9, the reflecting surface 12 is in the straight direction of the radiant heat, so
This radiant heat is not refracted and goes straight to the outside.

Since the material of the reflector 11 is aluminum foil, it does not provide a large resistance in the straight direction.

When the motor 16 rotates and the reflector 11 is tilted as shown by the dashed line in FIG. 1, the parallel light reflected by the reflector 9 is reflected by the reflective surface 12 and refracted as shown in FIG. The direction of reflection changes to go outside.

As shown in Fig. 4, the reflector 11 is formed of a large number of small reflecting surfaces 12 in the shape of a honeycomb in which hexagonal prisms surrounded by aluminum foil are adjacent to each other. It has good refractive properties.

In addition, since the material is highly reflective aluminum foil, the reflectance is high and heat loss is low.

The heating element 8 is a heater that includes visible light, and in this embodiment, the heating element 8 is a heater that includes visible light.
A high-temperature heater with a temperature of 00°C or higher is used, and all the diffusely reflected light rays generated by the heating element 8 are reflected and refracted by the reflective surface 12 of the reflector 11, so the reflected light is reflected on the entire surface of the reflector 11, creating a visual heating effect.

As described above, in this embodiment, the radiant heat of the heating element 8 can be automatically varied without rotating the reflecting plate 9 and the heating element 8 as in the conventional case.

Furthermore, in this embodiment, the reflector 11 is divided into two parts as shown in Fig. 3, and each part is configured to be freely rotatable, so that the angle of each anti-encloser 11 can be automatically varied to rotate the radiant heat in different directions, up and down. The heater can be rotated in the same direction and the heater can be heated according to the number of people and the location of the heater.

Effects of the Invention The present invention has a simple structure because the direction of reflection of radiant heat can be automatically changed to the surroundings of the stove body simply by automatically changing the reflector provided in front of the heating element.

In addition, since the reflector is composed of many reflective surfaces, the diffusely reflected light from the heating element is reflected by many reflective surfaces, and the radiant heat does not spread over a wide area of the stove, increasing the directionality of the reflected light and changing the heating position. becomes clear.

Since the reflector is made of a highly reflective material, it can be varied with little loss of radiant heat.

Since the reflector is formed of a large number of reflective surfaces, it is possible to prevent hands, etc. from coming into contact with the heating element, improving safety.

Since the diffusely reflected light rays are reflected on the reflector, visible light rays are reflected on the entire reflector, increasing the visual heating effect.
