Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric stove using a high temperature radiant heater that emits radiant heat including visible light.

Prior Art A conventional example (Japanese Unexamined Patent Publication No. 58-142128) is shown in FIG.
In Fig. 6, 1 is a main body, 2 is a reflector, 3 is a lamp heater, and 4 is a transparent plate made of a material that transmits infrared rays, such as heat-resistant glass, and its front surface has an uneven shape, for example, in the shape of a square pyramid. It is formed.

When the lamp heater 3 is energized, the heat rays pass through the transparent plate 4, are refracted at the front surface of the transparent plate 4, which has an uneven shape, and are diffused and radiated into the room. It has the effect of alleviating irritation to the eyes.

In addition, since the lamp heater 3 is covered by the transparent plate 4, it is safe because fingers and combustible materials do not come into direct contact with the lamp heater 3, and the front surface of the transparent plate 4, which has an uneven shape, prevents light from coming into contact with the lamp heater 3. The light is diffused and the entire surface of the transparent plate 4 shines even when viewed from an angle, making it look beautiful and at the same time warm.

Problems to be Solved by the Invention However, there is currently a problem that there is no suitable material for the transparent plate 4 used in such a configuration. In other words, the heat-resistant glass exemplified in the conventional example generally has poor transmittance for infrared rays with a wavelength of 2.7 microns or more, which reduces the warmth of electric stoves.

The present invention solves these conventional problems, and provides a beautiful electric stove that spreads warmth without reducing warmth and provides a beautiful glowing surface.

Means for Solving the Problems The electric stove of the present invention includes a high-temperature radiant heater that emits radiant heat including bright visible light, a reflection plate provided behind the high-temperature radiant heater, and a high-temperature radiant heater located in front of the high-temperature radiant heater. an aluminum honeycomb member having six walls and a large number of cells so as to cover the honeycomb member, and a motor that rotates the honeycomb member, the cell parts of the honeycomb member having an inclination angle in the thickness direction, The outer peripheral part of the member is in contact with the rotating part of the motor, and the outer peripheral part of the honeycomb member is rotated by the rotation of the motor, and the honeycomb member having an inclination angle is rotated in front of the high temperature radiant heater. .

Function Since the electric stove of the present invention has the above configuration, all the energy including visible light and infrared rays emitted from the radiant heater is hardly absorbed by the aluminum honeycomb member with an inclination angle. As the honeycomb member rotates, the cell inclination direction changes every moment in the circumferential direction, the radiation direction changes, and the radiant energy is spread over a wide area in front of the electric stove. The entire surface of the honeycomb member shines beautifully while heating.

Embodiment An electric stove according to an embodiment of the present invention will be described below with reference to the drawings. 1, 2, and 3, 5 is the main body, 6 is a reflector, 7 is a high-temperature radiant heater that emits visible light and infrared rays, and 8 is placed in front of the high-temperature radiant heater 7 so as to cover the heater 7. A drive motor 9 rotates the aluminum honeycomb member 8 at a low speed, and a motor gear 10 serves as a transmission for rotating the aluminum honeycomb member 8 from the drive motor 9. It is. FIG. 4 shows details of the aluminum honeycomb member 8. The aluminum honeycomb member 8 is made by gluing together a large number of thin aluminum foils 8a to form a large number of hexagonal cells 8b, where b is the cell dimension and t is the thickness of the honeycomb member. In this example, the cell size b
is about 3 mm, the thickness t of the honeycomb member is 5 mm, and the thickness of the aluminum foil 8a is about 30 μm.

In addition, the high temperature radiant heater 7 of this embodiment is a lamp heater in which a tungsten alloy is used for the heater wire, a quartz tube is used for the outer tube, an inert gas is sealed inside, and the heater wire temperature is set at 1000°C to 1500°C. is used. Therefore, it is brighter than electric wire heaters used in general atmospheric conditions.

Since this embodiment has the above configuration, the infrared rays including visible light emitted from the high temperature radiant heater 7 are
A part of the light passes straight through the cells 8b of the aluminum honeycomb member 8 along the inclination angle, and a part of the light passes through the cells 8b while being reflected by the walls of the cells 8b. Therefore, the entire surface of the aluminum honeycomb member 8 provided in front of the high-temperature radiant heater 7 shines beautifully, giving a warm feeling.

FIG. 5 shows a radiation distribution diagram of radiant energy when the radiant energy emitted from the high-temperature radiant heater 7 of the electric stove is reflected by the reflector 6 and radiated to the front of the electric stove via the aluminum handcam member 8. This is what I did. The aluminum honeycomb member 8 has a temperature distribution of radiant energy as shown in A in Fig. 5 when the tilt angle 8c of the aluminum foil rotates and moves upward, and the tilt angle 8c of the aluminum foil moves downward 180 rotations. Sometimes it becomes a radiation distribution of C radiation energy. For reference, the radiation distribution B of the radiant energy in FIG. 5 is when the inclination angle 8c of the aluminum foil 8a is parallel.

Therefore, by rotating the aluminum honeycomb member 8 with the aluminum foil 8a at an inclined angle, a radiation distribution can be obtained over a wide range, which is extremely convenient for the user when heating with an electric stove. We will provide electric stoves.

Furthermore, since there is no object through which heat rays pass, such as the transparent plate 4 of the conventional example, there is no reduction in energy caused by poor transmittance.

Effect of the invention The following effects can be obtained by the present invention.

(1) The cells of the honeycomb member are inclined in the thickness direction, and the honeycomb member rotates, so the radiation direction changes periodically, and the radiant energy spreads over a wide area in front of the electric stove, allowing heating over a wide area. .

At the copper one heating position, the radiant energy changes periodically, giving the person taking the heat a sense of the strength of the radiant energy and improving the heating sensation.

(2) The entire surface of the honeycomb member rotates while shining beautifully, so the shining cell surface changes periodically.
There is more sparkle and a warm sensation.

(3) The narrow metal honeycomb member guards the heater and prevents people, fingers, and combustible materials from coming into contact with the heater, making it highly safe.

(4) Since there is no object to transmit, there is no decrease in energy due to transmittance.
