Abstract

PURPOSE:To obtain radiant heating by the intermediary of heated air, by connecting a heat source producing hot air, a radiant panel of hot air type which consists of a hollow casing, and which has an inlet port and an outlet port for hot air, and a circulating fan, by a duct. CONSTITUTION:High-temperature combustion gas is produced by burning fuel by a burner in a combustion cylinder 19. Hot air is produced by transferring heat of combustion gas to the air flowing through the outside of the sealed container 20 of a combustion cylinder combined with a heat exchanger to trans mit heat, and the hot air is fed out of an outlet port 16 by a circulating fan 18. The hot air is fed into a panel from the inlet port 13 of a radiant panel 11 of hot air type via a duct 15. At that time, the hot air collides against a diffusion board 12, diffusing in the whole inside of a panel. Heat of hot air is transmitted to the surface of a panel and the air with lower temp. is dis charged from an outlet port 14. The air returns to a heat source 10 again from the inlet port 17 of a heat source 10, passing through the duct 15. The air is circulated by a circulating fan 18 from the heat source 10 through the duct 15, the radiant panel 11 of hot air type, and the duct 15 in sequence.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hot air radiant heating device that obtains radiation by utilizing hot air.

2. Description of the Related Art Conventional radiant heating devices include, for example, hot water type devices as shown in FIGS. 3 to 5. In the figure, 1 is a heat source for producing hot water, and this heat source 1 and a hot water radiant panel 2 are connected by a circulation pipe 3. Hot water produced by heat source 1 is circulated by pump 4. The hot water transfers heat to the panel surface while flowing through the vibro which is joined to the back surface of the hot water radiant panel 2 by the soldering material 5. The surface of the heated hot water radiant panel 2 becomes a radiant surface and exhibits a heating function.

Problems to be Solved by the Invention However, in the above configuration, since hot water is used as a heat medium, the temperature must be kept at 80°C or less to suppress boiling, and the hot water radiant panel 2 heated by this hot water Its surface temperature was 80°C at most, and it was necessary to increase its surface area in order to obtain the desired radiation ability. For this reason, it also rarely has the disadvantage of being limited in its installation locations. In addition, since hot water is used as a heat medium, if water leaks in the hot water path, not only will the walls and floors of the building become dirty, but the amount of water used as a heat medium will decrease, and ultimately the operation of the equipment itself will be affected. There was a drawback that it was impossible. In addition, since the hot water pump normally pressurizes the water to a moderate level of 1 klF/cm,
Since the flat panel expands and deforms, its path is limited to a circular vibrator-like cross section. For this reason, the hot water radiant panel 2 had the disadvantage that it had to have a complicated structure in which a vibro was bonded to the back surface of the panel by soldering, as shown in FIG.

The present invention aims to solve these conventional problems, and aims to obtain radiation by using hot air produced by a heat source as a heat medium.

Means for Solving the Problems In order to solve these problems, the present invention consists of a heat source that generates hot air, a panel-shaped box with a hollow interior, and an inlet and an outlet for the hot air. A hot air type radiant panel having a heat source and a circulation fan provided inside or outside the heat source are connected by a duct.

Effect With the above configuration, the high-temperature warm air generated by the heat source is sent into the interior from the inlet of the hot-air type radiant panel via the duct by the circulation fan, where it exchanges heat by heat transfer to the panel surface and becomes low-temperature hot air at the outlet. The air then returns to the heat source through the duct, where it is heated and becomes warm air.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings of FIGS. 1 to 3.

In the figure, 10 is a heat source, and there is this heat source 10 and a hot air type radiant panel 11 attached to an indoor wall, and this hot air type radiant panel 11 is a closed, flat box-shaped panel. A diffusion plate 12 is installed inside, and the back side of the panel has an inlet 13 and an outlet 14 for hot air, and a duct 15.
are connected to each of the heat sources, that is, the hot air outlet 16 and the inlet 17, thereby forming an air circulation path. The heat source 10 includes a circulation fan 18 and a combustion section 19 in a sealed case 117, and has a hot air outlet 16 at the top and an inlet 17 at the bottom. The combustion section 19 is still a closed container 20 that serves as both a combustion chamber and a heat exchanger, and a burner 21 is installed inside, and an exhaust port 22 is opened at the top.

In the above configuration, the burner 21 of the combustion section 19 burns fuel to produce high-temperature combustion gas, and heat is transferred between the combustion gas and the air flowing outside the closed container 2° which also serves as a combustion chamber and a heat exchanger. Warm air is generated and the hot air is sent out from the outlet 16 by means of a circulation system 7 and 8. The hot air enters the interior of the hot air radiant panel 11 through the entrance 13 of the hot air radiant panel 11 through the duct 15. At this time, the hot air collides with the diffuser plate 12, spreads throughout the inside of the panel, transfers heat to the panel surface, becomes low temperature, and blows out from the outlet 14. Furthermore, the hot air passes through the duct 15 and the entrance 17 of the heat source 10 and returns to the heat source 10 again.

As described above, air is circulated by the circulation fan 18 in the order of the heat source 10, the duct 15, the warm air type radiant panel 11, and the duct 15.

Since this device uses air as a heat medium, it can be heated to a higher temperature than water, and according to Kyoto theory, it can heat up to several hundred degrees.
Considering safety, warm air heated to 120-150°C is supplied to the hot air type radiant panel 11. In other words, since the prefectural style radiant panel 11 is heated to a higher temperature than when water is used as a heat medium, if the area is the same, more infrared rays or far infrared rays are emitted from that area than before, and a heating effect is exerted.

Conversely, the area of the panel can be reduced. In addition, if airtightness is violated, hot air will leak, but even if it does leak, there is no harm and the heating capacity will be slightly reduced, but operation can continue without any problems. Furthermore, the pressure of the static electricity of the circulating heat medium is low, and the circulation path does not necessarily have to be pipe-shaped, so it will not expand and deform, so the hot air radiant panel can be a simple box-shaped panel, and its structure is quite simple. It is simple and does not require complicated and advanced processing such as soldering. Effects of the Invention As described above, the hot air radiant heating device of the present invention provides excellent effects.

(1) Since air is used as a heat medium, it can be heated to a higher temperature than water. Hot air type radiant panels heated by this high-temperature air have a smaller surface area than conventional ones, but emit the same amount of infrared or far-infrared rays and have a heating effect. demonstrate.

(2) In the event that the airtightness of ducts, heat sources, hot air radiant panels, etc. is compromised, there will be no harm even if hot air leaks, and operation will continue without any problems, although the heating capacity will decrease slightly. can.

(3) Air, which is a circulating heating medium, has a low pressure and its circulation path does not necessarily have to be pipe-shaped, but it will not expand and deform, so hot air radiant panels can also be simple box-shaped panels, and their structure is It is extremely simple and does not require complex and advanced processing such as soldering.
