Abstract

PURPOSE:To enhance a heating efficiency, effect uniform radiation as a whole and widen a comfortable heating space by providing a radiant member applied with a far-infrared coating, which radiates radiant heat, between a reflecting plate and a heat source member. CONSTITUTION:A radiant member 17 disposed in front of a reflecting plate 15 is made of a stainless steel sheet or an aluminum-plated copper sheet, both being curved, and is constituted so as to have a given space 17a between the radiant member 17 and the reflecting plate 15. Combustion heat generated from a heat chamber 14 is in part radiated directly to the front side as radiant heat and is in part reflected by the reflecting plate 15 to be radiated as radiant heat. In the case of conventional radiation type heaters, radiation has been effected only from the portion of a reflecting plate, where the heat chamber is directly mirrored, and radiant heat from the upper part of the reflecting plate has not substantially been obtained. In the case of the heater of this invention, however, it is so designed that more uniform radiant effects are obtained by disposing the radiant member 17. Further, since square holes 18 are provided in the form of a lattice on the aforementioned radiant member, radiant heat from the reflecting plate 15 itself can also be radiated to the front side.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a radiant heater for home use.

Conventional technology Conventionally, the typical example of this type of radiant heater is the reflective kerosene stove. In the case of this stove, as shown in Fig. 6, a part of the heat generated by the firing of the heating cylinder 1, which serves as a heat source, is extracted directly or reflected by the reflector plate 2 to the front as radiant heat, making it easy to roast by hand. It is used for heating. Also, among the convection heat that escapes from the through holes 4 of the iron plate 3 and the front end 5 of the top plate to the upper part, the convection heat that escapes from the iron plate 3 to the upper part is used for heating hot water by placing a pot or kettle on it. .

Problems to be Solved by the Invention However, in the above-mentioned stove, most of the heat is convective heat that escapes upward from the through hole 4 of the top plate 3 and the front end 5 of the top plate, and only a small amount of radiant heat is radiated to the front (approximately 30% of the total). ), this resulted in poor efficiency, with high heating costs compared to the heat used for direct heating.

In addition, the central part of the heating tube 1, which serves as a heat source, tends to have a lot of radiant heat in front of its central part, but there is less radiant heat in the left and right directions, so it does not feel very hot. This has the disadvantage that the comfort of heating is impaired due to non-uniformity of radiant heat.

The present invention was made in view of these points, and aims to increase the amount of radiant heat to improve heating efficiency, and to uniformly radiate the heat throughout the room to expand the comfortable space for heating. be.

Means for Solving the Problems In order to solve the above problems, a first means of the present invention is to apply a far-infrared paint that emits radiant heat between the reflector plate placed behind the heat source body and the heat source body. A radiator is provided, and the second means further includes a grid-like or circular opening in the radiator.

Further, the third means is to provide a radiator having a grid-like or circular opening between the heat source and the front guard, and the fourth means is to further coat the radiator with far infrared rays. There is. Function The present invention uses the above-described structure to disperse and expand the heat from the heat source by the radiator, and by the radiator and the reflecting plate behind it,
Radiant heat can be sent forward.

In addition to the above-mentioned effect ζ, since the radiator is provided with an opening, the conduction of heat is accelerated, and the radiant heat by the reflector can also be sent forward efficiently. In addition, the visual effect can give a warm impression. Furthermore, in the third means, since the heat source is not directly visible, uneven radiation of radiant heat at the front is reduced, making it possible to obtain uniform and mild heating throughout. Furthermore, the fourth means can radiate far infrared rays.

Embodiments Hereinafter, embodiments of the present invention will be explained based on the attached drawings, taking the case of an open type kerosene stove as an example.

In Figures 1 to 3, Figure 11 shows the opening 1 at the top of the front.
2 is the main body of the kerosene stove, 13 is the front plate attached to the front lower part of the main body l1, and 14 is the open part 1 of the main body 11.
A heating tube that serves as a heat source is installed on the opposite side of 2, and is made up of a so-called glass chimney that emits heat rays forward. 15 is a reflector plate that radiates the radiant heat from the thermal cylinder l4 forward, 16 is a top plate attached to the top of the zero body 11 at 1F,
A retributive through-hole 16a is formed. 17 is the reflection plate 1
As shown in Figure 2, a radiator placed in front of 15 is a radiator made of stainless steel plate or marumi-plated copper plate, etc.
A certain space I7a is provided. Space 17a
It is possible to create air flow by providing
This radiator 17 can prevent the temperature of the cartridge tank 20 placed at the rear from increasing and becoming dangerous.Furthermore, as shown in FIG.
8, and its surface is coated with far-infrared radiation paint 19. This radiator 17 is held using a lower reflector 21 and an iron plate 16.

In the above structure, a part of the heat generated from the heat burner cylinder 14 is taken out as radiant heat directly to the front surface, and a part bounces off the reflector plate 15 and becomes radiant heat. At this time, in the past, the thermal cylinder 14 directly radiated heat only from the part reflected on the reflector 15, and there was almost no radiant heat from above the reflector, but by providing the radiator 17, the radiation is more uniform. It's starting to take effect.

Furthermore, since the radiator is also provided with square holes 18 in a grid pattern, the radiant heat from the reflector 15 itself can also be emitted forward.

FIGS. 4 and 5 show another embodiment of the present invention, in which the same parts as in the above embodiment are denoted by reference numerals, details are omitted, and different parts will be mainly explained. A radiator 17 is provided in front of the thermal cylinder 14, and is arranged along the curve of the guard 23. A hook 22 is provided at the end of the radiator 17, and the guard 19 is used to secure the radiator 17. , this radiator also has a grid-like opening 18 at 17°.
A plurality of "" are provided and a far-infrared vA paint 19 is applied.

In the above configuration, the thermal sintering heat generated from the thermal sintering cylinder 14,
Both of the radiant heat reflected by the reflecting plate 15 pass through the opening 18' in part of the radiator 17', and part of the radiant heat reheats the radiator 17' itself, radiating it and generating far infrared rays. Therefore, compared to the case without the radiator 17", more uniform and more efficient comfortable heating can be obtained, and although the direct visual warmth is slightly less, the overall heating is mellower than before. You can get a feeling.

Although the above embodiments have been explained using a kerosene stove as an example, the explanation is not limited to this, and the same applies to any type of heating device that uses radiant heat from a heat source such as a heating cylinder. Effects can be obtained.

(1) It becomes possible to re-reflect and dissipate the radiant heat from the heat source over a wider area, and fuel can be used more efficiently from the perspective of direct heating through radiation.

(2) By providing a large number of holes in the radiator, the overall heat transfer can be improved, and the radiant heat of the reflector itself can also be sent forward.

(3) By arranging the radiator in front of the heat source, the radiant heat can be made uniform in all directions, improving heating efficiency and increasing the visual heating effect.
