Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a heater using a gas-fired or kerosene-fired far infrared radiation heater as a heat source.

[Conventional technology]

A heater that uses a gas-fired or kerosene-fired far-infrared radiant heater as a heat source is different from the conventional heating method that directly heats the air, and instead of heating the air in the middle, it changes into heat by directly contacting it with clothes or skin. Since it uses infrared rays for heating, it can perform extremely natural heating, especially for large spaces with a high ceiling such as factories, warehouses or gymnasiums, and large areas of ventilation. It is suitable for use in, and the demand for wealth is increasing recently.

On the other hand, it was considered that the heater is also used for spot heating of a small space by utilizing the characteristics of the far infrared radiation heater. However, since the conventional heater of this kind is made for the purpose of being used in a large space such as a factory or a warehouse or a place with a lot of ventilation as described above, the total length is, for example, 5 to 10 m,
Since it weighs about 100 to 250 kg and is not suitable for spot heating in a small space, it is necessary to reduce the length to about 1 to 2 m and the weight to about 30 kg.

[Problems to be solved by the device]

However, if the total length of the heater is shortened, the length of the radiant pipe inside will also be shortened, and the radiation amount of far infrared rays will also be reduced, making it impossible to exert a sufficient heating effect. If convection can be promoted, it is possible to exert a further heating effect, but in the case of a conventional far infrared radiation heater in which a large one is simply downsized,
Structurally, we could not expect much of that effect.

That is, FIG. 10 is a cross-sectional view showing an example of a conventional far-infrared radiation heater, in which A is a reflection plate B on the inner surface,
Further, in the inside of the airframe in which a far-infrared radiation tube C is piped, a louver D is attached to the front radiation port of this aircraft A, and the far-infrared rays emitted from the radiation tube C are
The heat generated in the airframe A by heating the radiant tube C in the heater configured as described above is partly directed to the front through the louver D. Although natural convection occurs, most of it is trapped inside the airframe A as indicated by the arrow t ... and does not convection outside, so the heating effect to sufficiently warm the indoor air cannot be exhibited.

Therefore, the technical problem of the present invention is to provide a far-infrared radiant heater capable of naturally convection of heat generated from a radiant tube to the outside of the fuselage and heating with both far-infrared rays and heat convection. is there.

[Means for Solving the Problems]

Means taken in the present invention to solve the above technical problems are as follows.

(1) Side plates are connected in a substantially C-shape so as to gradually open to the front on the left and right sides of the back plate, and the front openings of these left and right side plates are radiation ports, and In a heater configured to radiate a far-infrared ray radiated from the radiation tube inside the fuselage with a reflector plate on its side surface and to radiate it through a louver attached to the radiation port on the front of the fuselage. (2) The entire louver is attached to the front ends of the left and right side plates by being supported by a plurality of support legs attached inwardly at substantially right angles and projecting forward from the radiation port. As a result, the entire heater is formed to have a bilaterally symmetrical cross section of a substantially hexagonal shape, and the gap between the outer frame of the louver and the radiation port is used as a convection heat discharge port.

However, in this case, the radiant tube means one that is heated by the combustion gas sent from the combustion chamber and radiates a heat ray mainly composed of far infrared rays from the outer surface of the tube.

[Action]

 The above means operate as follows.

The element of (1) above emits far-infrared rays emitted from a heated radiation tube directly or by being reflected by a reflection plate and intensively emitted from the louver to the front side of the body, and the emitted far-infrared rays are directly emitted to the human body. By applying it to the floor surface from and to convert it into heat, it is possible to exert an excellent heating effect.

The element of the above (2) is a relationship in which the entire heater is formed in a substantially hexagonal cross section, and the heat accumulated in the body due to the heating of the radiant tube is opened to the front on the left and right side plates of the body ( The heat flow is gradually convected to the front side radiation port side along the reflection plate), and this heat flow is discharged between the left and right side plates, that is, the louver outer frame formed approximately at right angles to the convection direction of the heat flow and the radiation port. Since natural convection can be efficiently carried out to the outside of the airframe from the outlet, it is possible to directly heat the air in a small space.

As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.
