Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric stove using a high temperature radiant heater that emits heat over a width that includes visible light.

Conventional technology A conventional example is shown in FIG.

In the conventional structure, a main body 4 equipped with a high temperature radiant heater 2 and a reflector 3 is rotatably supported by a central shaft 6 on the upper part of the leg 1.
A motor 6 provided inside rotates the main body 4 from side to side via a crank mechanism.

Further, on the front surface of the high-temperature radiant heater 2, a porous member 7 made of an aggregate of reflective cells is provided.

Details of the porous member 7 are shown in FIG.

The porous member 7 is made by joining together a large number of thin aluminum foils 7a to form a large number of hexagonal cells b, where b is the cell size,
t is called the thickness of the porous member 7.

When the heater 2 is energized, some of the infrared rays including visible light emitted from the high-temperature radiant heater 2 go straight through the self-b of the porous member 7, and some of them pass through the self-b while being reflected by the wall surface of the self-b. do.

Therefore, the porous member 7 provided on the front surface of the heater 2 has the effect of giving a bright and warm feeling to the entire surface. .

Problems to be Solved by the Invention However, in order to emit more of the infrared rays emitted by the heater 7 forward, it is necessary to reduce the thickness of the aluminum foil 4a to reduce the resistance of the infrared rays traveling straight. In order to make the entire surface of the porous member 4 shine beautifully, the thickness of the aluminum foil 4a cannot be made too thick, so the thickness of the aluminum foil 4a is reduced to about 30 μm. I am my friend.

Therefore, the porous member 7 becomes lightweight, and when the main body 4 rotates, the porous member 7 resonates on the contact surface of the reflector plate 3, causing a problem in that it generates sound.

The present invention solves these conventional problems and provides an electric stove that does not generate resonance noise when the main body rotates.

Means for Solving the Problems In the electric stove of the present invention, the porous member is constituted by an aggregate of a plurality of reflective cells, a frame is provided around the periphery of the aggregate, and the porous member has a width of the frame. It is cut to the same size or larger and installed inside the frame.

Function Since the electric stove of the present invention has the above-mentioned configuration, the porous member is in close contact with the frame, and when the main body rotates from side to side, the porous member does not resonate with the main body, thereby preventing the generation of sound.

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

In FIG. 1, 8 is a stove body, 9 is a high-temperature radiant heater, and on the back of the high-temperature radiant heater 9, a reflector plate 10 having a parabolic cross section is fixed to the stove body 8 via a side reflector plate 11. . Similarly, the high temperature radiant heater 9 is fixed to the side reflection plate 11 and is located approximately at the focal point of the parabolic shape of the reflection plate 10.

A porous member 12 is located over the entire opening of the reflection plate 1o on the front side of the high-temperature radiant heater 9.

The porous member 12 has a large number of honeycomb-shaped reflective cells 13 in which hexagonal columns surrounded by foil are adjacent to each other as shown in FIG.
The material is aluminum, a highly reflective material.
The cell size of the porous member 12 is approximately 3 MN and the thickness of the porous member 12 is 5 MM. Furthermore, a frame 16 having inwardly bent pieces 15 at the front and rear ends is provided around the entire circumference of the peripheral edge 14 of the porous member 12.

The porous member 12 is cut to a width equal to or larger than the width A of the frame 16 and is installed in the frame 16.

A knob portion 17 is formed on a part of the bent piece 16 of the frame body 16, and a convex portion 19 is formed on the support surface 18 of the frame body 16 on the stove body 8.

Furthermore, in the high temperature radiant heater 9 of this embodiment, 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 15°C.
A rung heater heated to 00°C is used. Therefore, it is brighter than electric wire heaters used in general atmospheric conditions.

2o is a motor that rotates the main body left and right via a link mechanism, and 21 is a leg.

Since this embodiment has the above-described configuration, part of the infrared rays including visible light emitted from the high-temperature radiant heater 9 travels straight through the cells of the porous member 12, and part of it is reflected by the walls of the reflection cells 13. while passing through the cell. Therefore, the high temperature radiant heater 9
The entire surface of the porous member 12 provided on the front side of the device shines beautifully,
It provides a warm sensation and in fact prevents unnecessary loss of radiant heat in the longitudinal direction of the heater 9, causing a spread 9 in the right angle direction.

The porous member 12 is formed by aligning nine pieces of aluminum foil to form a large number of hexagonal cells, so it has strength in the depth direction and elasticity in the width direction.

Since the porous member 12 is always installed in the frame 16 in a compressed state, its elasticity allows it to be closely fixed to the frame 16, so that no resonance noise is generated when the main body 4 rotates left and right. .

Further, the porous member 12 has its entire circumference connected to the frame body 16 and the bent piece 1
Since it is surrounded by 6, it can be installed on the stove main body 8 in a two-dimensional manner without deformation. This gives you a beautiful shine. In addition, the support surface 1 provided on the stove body 8
Since the frame 16 is locked to the convex portion 19 of 8, the porous member 12 can be easily attached and removed together with the frame 16, and it is also possible to remove dust from the porous member 12 and clean the reflective plate 10 during use. It is.

Further, the porous member 12 can be easily attached and removed using the knobs 17, and since the knobs 17 are provided on both sides of the porous member 12 in the depth direction, either the front or back can be used.

Furthermore, since the porous member 12 is reinforced by the frame 16 and the folded piece 15, the foil thickness of the porous member 12 can be made even thinner.
Improves the transparency of radiant energy.

Effect of the invention According to the present invention, the following effects can be obtained.

(1) Since the porous member is closely fixed to the frame, no resonance noise is generated when the main body rotates from side to side.

? ) The strength of the porous material has been improved and it can be installed flat on the main body, giving a beautiful shine to the entire surface of the stove and increasing the sense of warmth.

(3) Since the porous member can be easily attached to and removed from the main body, cleaning of the porous member and the reflective plate can be easily performed.

(4) Since the porous member is reinforced by the frame, the foil thickness of the porous member can be made even thinner, and the permeability of radiant energy can be increased.

(b) The porous member guards the heater and prevents people's fingers or combustible materials from coming into immediate contact with the heater, resulting in high safety.
