Abstract

PURPOSE:To make it possible to enlarge the effective radiation distribution by providing a porous member with a plurality of reflector cells in the front face of a radiation heater. CONSTITUTION:Part of infrared light beams containing visible light beams which is emitted from a radiation heater 9 advances straight through the cells 10a of a honey-comb 10 made of aluminium, and other part is reflected on the wall face of the cells 10b and passes through them. Accordingly the aluminium honey-comb 10 provided on the front face of the radiation heater 9 glows beautifully on entire surfaces, giving the feeling of warmth and preventing unnecessary loss of the radiation heat in the longitudinal direction of the radiation heater 9 and the radiation heat is expanded at right angle, that is, in the right and left directions in view of the front face of an electric stove. Furthermore, the honey-comb 10 prevents contact with human fingers and combustible objects with the radiation heater 9 and contributes to safety improvement.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric stove whose main body rotates from side to side.

BACKGROUND OF THE INVENTION Conventional electric stoves of this type have been developed, for example, by
As shown in Publication No. 3105, it had a structure as shown in Figure 6.

That is, a main body 4 with a heater 2 and a reflector 3 mounted on the upper part of the leg 1 is rotatably supported by a central shaft 5, and a crank mechanism is fully operated by a motor 6 provided in the leg 1 to rotate the main body 4. It is configured to rotate from side to side.

Problems to be Solved by the Invention However, with such a structure, it is warm when the main body 4 is facing the human body, but when the main body 4 rotates,
There was a problem that it was not warm when facing in a direction tilted to the left or right. This is due to the following reasons.

In general, electric heaters, including this conventional example, are provided with two heaters positioned at the focal point of a parabolic reflector 3, and a portion of the radiant heat emitted from the heater 2 is reflected by the reflector 3. It is ejected almost parallel to the front, and some of it is emitted directly forward in a radial direction. As a result, as shown in Fig. 7, the area with equal energy at 5 and the warm feeling surrounded by line E (
(hereinafter referred to as radiation distribution), the front is long but narrow. Therefore 7
When used while rotating left and right with this electric stove at a distance of 0 to 100 degrees, the above-mentioned problem occurs.

Therefore, the present invention widens the radiation distribution to the left and right, thereby extending the time period during which the user feels warm even when the main body rotates left and right.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to provide a plurality of reflective panels in front of the radiant heater. A porous member with a hole is provided.

Function Since the present invention has the above configuration, the radiant heat emitted from the radiant heater is reflected on the walls of the plurality of reflection cells, and
Or on reflex? Since it passes through the holes in the hole and is emitted to the front, the entire effective radiation distribution can be achieved.

EXAMPLE Hereinafter, an electric stove according to an example of the present invention will be described with reference to the drawings. In Figures 1 and 2, 7 is the main body, 8 is a reflector, 9 is a high-temperature radiant heater that emits visible light and infrared rays, and 10 is provided in front of the radiant heater 9 so as to cover the radiant heater 9. It is a porous member, and in this example, an aluminum honeycomb is used.

FIG. 3 shows details of the aluminum honeycomb 10.

7r Remi honeycomb 1o is thin iris foil 10a
f A large number of hexagonal reflection cells 10b are formed by gluing together a large number of them, and b is the cell dimension and tk is called the thickness of the honeycomb. In this example, the center dimension is approximately 3 m, the thickness of the honeycomb is 5 m, and the thickness of the aluminum foil 10a is approximately 30 μm.
It is m.

Furthermore, in the radiation heater 9 of this embodiment, a tungsten alloy is used for the heater wire, a quartz tube is used for the outer tube, and an inert force is completely enclosed inside the heater wire, so that the temperature of the heater wire can be adjusted. 1000℃~15oO
A lamp heater heated to ℃ is used. Therefore, it is brighter than electric wire heaters used in general atmospheric conditions.

11 is a motor that rotates the main body left and right via a link mechanism, and 12 is a leg.

Since this embodiment has the above-described configuration, some of the infrared rays emitted from the radiant heater 9 include all the visible rays. It travels straight through the sage 10b of the Remi honeycomb 10, and some of the light travels straight through the sage 10b, reflecting off the wall of the 10b, and then passing through the sage 10bi.

Therefore, the entire surface of the aluminum honeycomb 101- provided on the front side of the radiant heater 9 shines beautifully, giving a warm feeling, preventing unnecessary loss of radiant heat in the longitudinal direction of the radiant heater 9, When viewed from the front, it creates an expansion in the left and right direction. This situation is shown in FIG.

In particular, in the case of an electric stove that uses the radiant heater 9 vertically as in this embodiment, it is possible to prevent the floor surface temperature from rising, so the radiant heater 9 can be installed near the floor surface and have the effect of warming the feet from the side. There is.

Furthermore, the honeycomb 10 prevents human fingers and combustible materials from coming into contact with the radiant heater 9, thereby improving safety.

FIG. 5 shows a second embodiment of the invention. In the second embodiment, unlike the vJl embodiment in which the radiant heaters 9 are provided vertically, two radiant heaters 9 are provided horizontally, and the other configurations are the same. In this case as well, the same effect as in the first embodiment prevents all unnecessary radiation in the longitudinal direction of the radiant heater 9 and causes it to spread in the perpendicular direction. Therefore, as an electric stove, it is possible to spread in the vertical direction while appropriately restricting the spread in the left-right direction, so that the height can be reduced, which is an effect unique to the second embodiment.

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

(1) It prevents unnecessary radiant heat from being radiated in the longitudinal direction of the radiant heater, causing it to spread in the right angle direction, and when the main body is rotated from side to side, the heating time becomes longer.

(21 The entire surface of the porous material shines beautifully, improving the interior design and increasing the sense of warmth.

(■ High safety because the porous member prevents people's fingers and combustible materials from coming into contact with the heater.

(If the 4 radiant heaters are installed vertically, it is possible to prevent the floor temperature from rising excessively and to warm the feet from the sides.

(5) When the radiant heater is installed horizontally, the radiant heat can be spread in the vertical direction, and the height of the main body can be lowered.

(6) There is no reduction in energy consumption due to transmittance, unlike when using a glass diffuser plate.
