[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating device using combustion heat, and more particularly to a heating device using radiant heat.

[0002]

2. Description of the Related Art A conventional heating device of this kind is disclosed in
What was described in 11548 gazette was common. This heating device comprises a burner 1 provided at the lower part of the main body 10 as shown in FIGS. 7 and 8, a hollow thin box-shaped heat exchanger 2 for passing the combustion gas from the burner 1, and both sides of the heat exchanger. , A far-infrared paint 4 applied to at least the front surface of the heat exchanger 2, a far-infrared paint 4 applied to at least the front surface of the heat exchanger, A convection fan 5 that sends air to the exchanger 2 to exchange heat and discharge it as warm air from the main body discharge port 9. The heat exchanger 2 is hollow so that the combustion gas 6 from the burner 1 passes therethrough. A passage 6 is provided by forming a hollow, and a concave bead 8 is provided in a part of the passage 7 so that the combustion gas can be distributed to each part of the heat exchanger.
It was configured to be discharged from.

[0003] The combustion gas generated by the burner passes through the heat exchanger 2 and is heated to 300 ° C to 500 ° C to radiate far-infrared rays from the front surface coated with far-infrared paint to perform radiant heating. At the same time, the indoor air taken in by the convection fan 5 is blown along the rear surface of the heat exchanger 2, mixed with the combustion gas discharged at the opening 3 of the heat exchanger 2, and discharged into the room as warm air. Perform heating.

[0004]

However, in the above-described conventional heating apparatus, the surface of the heat exchanger on which the far-infrared paint is not applied has a high temperature, and is taken in by the convection fan 5 along the rear surface of the heat exchanger 2. Blown indoor air, and heat exchanger 2
The heat of the surface on which the far-infrared paint is not applied is heat-exchanged into hot air, mixed with the combustion gas discharged from the opening 3 of the heat exchanger 2, and discharged into the room as hot air. Therefore, warm air is always blown out from the main body discharge port during radiant heating. Further, the radiation efficiency is reduced because the heat exchanger is always cooled. Further, since the temperature of the entire heat exchanger rises, radiation is also generated from a surface other than the surface where the far-infrared paint is applied, and the inside of the main body and the convection fan 6 are heated by the radiation from the heat exchanger.

[0005] In recent years, there has been a demand from heating users that a feeling of airflow tends to be disliked in heating using warm air. There is also the problem of mite dung allergens that are heated by hot air.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to realize a heater capable of preventing a rise in the temperature inside the main body and realizing high-efficiency radiant heating in which hot air is not blown out.

[0007]

In order to solve the above-mentioned problems, the present invention comprises a high-temperature gas generating means for generating a high-temperature gas, a heat-collecting surface heated by the heat of the high-temperature gas, and a radiation surface for generating radiant energy. A radiator that has a hole that penetrates from the holding surface to the radiation surface, a radiator heating air path that guides high-temperature gas to the radiator heating surface, and a connection that connects the radiator heating air path and the high-temperature gas generating means. It is composed of a heat shield plate that forms a heat shield space provided with an inlet and a heat shield space outlet adjacent to the inlet and the radiator above the radiator heating air path and the radiator heating air path.

[0008] With the above structure, since a hole is provided in the radiation surface, the high-temperature gas flows from the radiator heating air path to the radiation surface of the radiator and becomes an ascending airflow, and radiates from both the heat collection surface and the radiation surface. The heat transfer area when the body is heated and the hot gas transfers heat to the radiator is enlarged. The holes reduce the development of the boundary layer and increase the heat transfer coefficient, so that the heat of the high-temperature gas is efficiently transmitted to the radiation surface, and the radiation energy is efficiently released from the radiation surface into the room, thereby radiating and heating the human body and the like. . On the other hand, the radiator heating air passage is also heated by the high-temperature gas, and the air in the heat shielding space is heated. The air in the heat shield space rises and creates a flow from the heat shield space inlet to the heat shield space outlet. Further, the high-temperature gas flowing out of the hole of the radiator becomes a rising airflow at the upper part of the radiator due to the draft action, but the air in the heat shield space near the outlet of the heat shield space above the radiator is attracted by the ejector effect. Therefore, a weak flow is generated from the heat shielding space entrance to the heat shielding space outlet, and the temperature of the air in the heat shielding space is prevented from rising. Therefore, since the heat shield space is not forcibly cooled by the air, the heat conduction from the radiator radiator heating air passage to the heat shield plate can be reduced, and the temperature inside the main body can be prevented from rising.

With the above configuration, since the radiator has a hole, the high-temperature gas flows from the radiator heating air path to the radiant surface of the radiator and becomes an ascending airflow, thereby heating the radiator from both the heat collecting surface and the radiant surface. However, the heat transfer area when the high-temperature gas transfers heat to the radiator is enlarged. The holes reduce the development of the boundary layer and increase the heat transfer coefficient, so that the heat of the high-temperature gas is efficiently transmitted to the radiation surface, and the radiation energy is efficiently released from the radiation surface into the room, thereby radiating and heating the human body and the like. . On the other hand, the radiator heating air passage is also heated by the high-temperature gas, and the air in the heat shielding space is heated. However, the air in the heat shield space rises,
A flow is created from the heat shield space entrance to the heat shield space outlet.
Therefore, a flow occurs from the heat shield space inlet to the heat shield space outlet, preventing a rise in the temperature of the air in the heat shield space, and reducing heat conduction from the radiator heating air passage to the heat shield plate.
The temperature inside the main body can be prevented from rising.

A heating device according to a third aspect of the present invention, in addition to the configuration of the first and second aspects, further comprises a heat shield space outlet surrounding the radiator heating air passage and adjacent to above the radiator. The configuration is such that a heat shield plate that forms a space is provided. With the above configuration, the heat collection surface and the radiation surface are heated by the heat of the high-temperature gas generated by the high-temperature gas generation means, and radiation energy is released from the radiation surface to radiantly heat the room.

On the other hand, the radiator heating air passage is also heated by the high-temperature gas, and the air in the heat shielding space is heated. However, the air in the heat shield space rises and creates a flow from the heat shield space inlet to the heat shield space outlet. In addition, the high-temperature gas flowing out of the radiating surface heating air passage or the radiator hole becomes a strong updraft at the upper part of the radiator due to the draft action, but the air in the heat shield space near the outlet of the heat shield space above the radiator is ejected. Attract by effect. Therefore, a flow occurs from the heat shield space inlet to the heat shield space outlet, thereby preventing the temperature of the air in the heat shield space from rising. Therefore, heat conduction from the radiator heating air passage to the heat shield plate can be reduced, and the temperature inside the main body can be prevented from rising.

According to a fourth aspect of the present invention, in addition to the first, second and third aspects of the present invention, a heat shield space surrounding the radiator heating air path and having a heat shield space entrance provided below the radiator is provided. Is provided with a heat shield plate. With the above configuration, the heat collection surface and the radiation surface are heated, and radiation energy is released from the radiation surface to radiantly heat the room.

On the other hand, the radiator heating air passage is also heated, and the air in the heat shielding space is heated. Then, cool air is introduced into the heat shield space from the heat shield space entrance below the radiator and creates a flow toward the heat shield space outlet by a draft action, thereby preventing a rise in the temperature of the air in the heat shield space.

According to a fifth aspect of the present invention, in addition to the first, second, third, and fourth aspects, the heating apparatus further comprises a heat shield for guiding wind generated by the cooling air blowing means to the heat shield plate. It has a plate cooling air passage, and an outlet of the heat shielding plate cooling air passage is provided adjacent to a heat shielding space outlet. When the amount of heating of the high-temperature gas generating means is large, the radiator heating air passage is heated to a high temperature by the high-temperature gas, and heat conduction and radiation energy are blocked by the heat shield plate, while heat energy is transmitted to the heat shield plate. . However, in this configuration, it is possible to prevent the temperature inside the main body from increasing without reducing the amount of radiation by cooling the radiant body heating air passage without cooling the radiant body heating air flow, by flowing the wind generated by the cooling air blowing means to the heat shield plate. it can.

Further, the radiator heating air passage is heated by the high-temperature gas, and the temperature of the air in the heat shielding space is also increased. The air in the heat shield space rises and creates a flow from the heat shield space inlet to the heat shield space outlet. Then, the air in the heat shield space near the heat shield space outlet is attracted by the ejector effect of the cooling air flowing out from the outlet of the heat shield plate cooling air passage provided adjacent to the heat shield space outlet. Therefore, a flow occurs from the heat shield space inlet to the heat shield space outlet, and the temperature rise of the air in the heat shield space is further prevented, and the temperature inside the main body is prevented from rising.

According to a sixth aspect of the present invention, there is provided a heating apparatus according to the first, second, third, fourth, and fifth aspects, wherein the heat shield plate is made of aluminum having an emissivity of 0.1. The radiator heating air passage is made of a plated steel sheet and has an emissivity of 0.
Fifteen galvanized steel sheets are used, and the emissivity of the heat shield plate is equal to or less than the emissivity of the radiator heating air passage.

When the heating amount of the high-temperature gas generating means is large, the radiator heating air passage is heated to a high temperature by the high-temperature gas to generate radiant energy. However, since the emissivity of the heat shield is less than or equal to the radiator heating air path, the radiant energy is reflected and blocked by the heat shield. The generated radiant energy is reflected and transmitted between the radiator heating air passage and the heat shield plate, and is radiated indoors from the heat shield space entrance and the heat shield space outlet. Therefore, the temperature rise inside the main body can be suppressed, and the radiation generated in the radiator heating air passage can be effectively used for indoor heating.

In the figure, reference numeral 11 denotes a high-temperature gas generating means for generating a high-temperature gas for generating a high-temperature gas such as a circular burner for burning oil or gas fuel, and 12 denotes a heat-collecting surface 13 heated by heat of the high-temperature gas and a high-temperature gas. The radiator is a radiator having a radiating surface 14 coated with a ceramic material such as a metal oxide having an emissivity of 0.9 when heated and generates radiant energy.

The heat shielding space is formed of a heat shielding plate made of an aluminum-plated steel sheet having an emissivity of 0.1. With the above structure, the heat collecting surface 13 and the radiation surface 14 are heated to 300 ° C. by the 400 ° C. high-temperature gas generated by the high-temperature gas generating means, and far-infrared radiation energy having a wavelength of 4 μm or more is emitted from the radiation surface 14 to radiate the room. Heat up. On the other hand, the radiator heating air passage 16 is also heated to 200 ° C. by the high temperature gas, and the temperature of the air in the heat shielding space 21 is increased. The air in the heat shield space rises by the draft action, and creates a flow from the heat shield space inlet to the heat shield space outlet. Further, the high-temperature gas flowing out of the radiation surface heating air path 15 becomes a strong ascending airflow at the upper part of the radiator 12 due to the draft action, but the air in the heat shield space near the heat shield space outlet 19 above the radiator is ejected by the ejector effect. To attract. Further, cool air is introduced into the heat shield space 21 from the heat shield space inlet 18 below the radiator.
Therefore, a flow is generated from the heat shield space inlet 18 to the heat shield space outlet 19 to prevent the temperature of the air in the heat shield space 21 from rising and to reduce the heat conduction from the radiator heating air passage 16 to the heat shield plate 20. Thus, the temperature inside the main body 22 can be prevented from rising.

When the amount of heating of the high-temperature gas generating means is large, the radiator heating air passage 16 is heated to a high temperature by the high-temperature gas to generate radiant energy. However, since the emissivity of the heat shield plate 20 is equal to or less than the radiant body heating air path 16, the radiant energy is reflected and blocked by the heat shield plate 20. Also,
The generated radiant energy is reflected and transmitted between the radiator heating air passage 16 and the heat shield plate 20, and is radiated indoors from the heat shield space entrance 18 and the heat shield space outlet 19. Therefore, the main body 22

This is a radiator having a radiation surface 25 coated with a ceramic coating such as a metal oxide having an emissivity of 0.9 and having a hole 26 penetrating from the heat collecting surface 24 to the radiation surface 25. A radiator heating air passage 16 made of a galvanized steel sheet having an emissivity of 0.15, which guides a high-temperature gas to the heat collecting surface 24 of the radiator 23, is connected to the high-temperature gas generating means 11 by a connecting air passage 17. An aluminum plating having an emissivity of 0.1, which surrounds the radiator heating air passage 16, has a heat shield space inlet below the radiator, and has a heat shield space outlet adjacent above the radiator to form a heat shield space. It consists of a heat shield made of steel plate. With the above configuration, the radiation surface 26
The high-temperature gas of 400 ° C. generated by the high-temperature gas generating means flows from the radiator heating air passage 16 to the radiating surface 25 of the radiator, forming a rising airflow. The radiator is heated from both sides of the radiator 25, and the heat transfer area when the high-temperature gas transfers heat to the radiator is enlarged. The hole 26
Since the development of the boundary layer is reduced and the heat transfer coefficient is increased, the heat of the high-temperature gas is efficiently transmitted to the radiating surface 25, and the radiating surface is heated to about 300 ° C., and radiant energy having a wavelength of 4 μm or more is emitted from the radiating surface into the room. Radiated heating and heating of the human body etc. are efficiently released.

On the other hand, the radiant body heating air passage 16 is also heated to 200 ° C. by the high temperature gas, and the temperature of the air in the heat shielding space 21 is raised. The air in the heat shield space rises by the draft action, and creates a flow from the heat shield space inlet to the heat shield space outlet. Further, the high-temperature gas flowing out of the hole 26 becomes a strong updraft at the upper part of the radiator 23 due to the draft action, but attracts air in the heat shield space near the heat shield space outlet 19 above the radiator by an ejector effect. Cool air is introduced into the heat shield space 21 from the heat shield space inlet 18 below the radiator. Therefore, a flow is generated from the heat shield space inlet 18 to the heat shield space outlet 19 to prevent the temperature of the air in the heat shield space 21 from rising and to reduce the heat conduction from the radiator heating air passage 16 to the heat shield plate 20. Thus, the temperature inside the main body 22 can be prevented from rising.

When the amount of heating of the high-temperature gas generating means is large, the radiator heating air passage 16 is heated to a high temperature by the high-temperature gas to generate radiant energy. However, since the emissivity of the heat shield plate 20 is equal to or less than the radiant body heating air path 16, the radiant energy is reflected and blocked by the heat shield plate 20. Also,
The generated radiant energy is reflected and transmitted between the radiator heating air passage 16 and the heat shield plate 20, and is radiated indoors from the heat shield space entrance 18 and the heat shield space outlet 19. Therefore, the main body 22
The internal temperature rise can be suppressed, and the radiation generated in the radiator heating air passage can be effectively used for indoor heating.

(Embodiment 3) FIG. 5 is a cutaway perspective view of a main part of a heating apparatus according to Embodiment 3 of the present invention, and FIG. 6 is a transverse sectional view. In the figure, reference numeral 11 denotes a high-temperature gas generating means for generating a high-temperature gas for generating a high-temperature gas such as a circular burner for burning oil or gas fuel, and 23 denotes a heat collecting surface 24 heated by the heat of the high-temperature gas and a radiant energy. This is a radiator having a radiation surface 25 coated with a ceramic coating such as a metal oxide having an emissivity of 0.9 and having a hole 26 penetrating from the heat collecting surface 24 to the radiation surface 25. A high temperature gas of about 450 ° C. is introduced to the heat collecting surface 24 of the radiator 23, and the emissivity is 0.1.

A heat shield space outlet is provided adjacent to the upper side of the radiator, and a heat shield plate made of an aluminum-plated steel sheet having an emissivity of 0.1 to form the heat shield space is provided. Having a heat shield plate cooling air passage 28 for guiding the wind generated at 27,
An outlet 29 of the heat shield plate cooling air passage is provided adjacent to the heat shield space outlet.

With the above arrangement, since the radiation surface 26 is provided with a hole, the high-temperature gas of 400 ° C. generated by the high-temperature gas generating means flows from the radiant heating air passage 16 to the radiant surface 25 of the radiator, and the rising airflow is generated. As a result, the radiator is heated from both the heat collecting surface 24 and the radiation surface 25, and the heat transfer area when the high-temperature gas transfers heat to the radiator is enlarged. Since the hole 26 reduces the development of the boundary layer and increases the heat transfer coefficient, the heat of the high-temperature gas is efficiently transmitted to the radiation surface 25 on the radiation surface.
C., and the far-infrared radiation energy having a wavelength of 4 μm or more is efficiently emitted from the radiation surface into the room, thereby radiantly heating and heating the human body and the like.

On the other hand, when the heating amount of the high-temperature gas generating means is large, the high-temperature gas becomes 450 ° C. or more, and the radiator heating air passage 16 is heated to a high temperature of about 300 ° C. While the energy is blocked, the heat shield 2
Thermal energy is transferred to zero. However, in this configuration, without cooling the radiant body heating air passage 16, the air generated by the cooling air blowing means 27 is flown and cooled to the heat shield plate 20, so that the temperature inside the main body 22 can be increased without reducing the radiation amount. Can be prevented.

Further, the radiator heating air passage 1
6 is heated and the temperature of the air in the heat shield space is also raised. The air in the heat shield space rises and creates a flow from the heat shield space inlet 18 to the heat shield space outlet 19. The air in the heat shield space near the heat shield space outlet is attracted by the ejector effect of the cooling air flowing out of the outlet 29 of the heat shield plate cooling air passage provided adjacent to the heat shield space outlet. Therefore, a flow occurs from the heat-shielding space inlet to the heat-shielding space outlet, and the temperature rise of the air in the heat-shielding space can be further prevented, and the temperature inside the main body can be prevented from rising.

The radiator also flows on the radiation surface of the radiator and becomes an ascending airflow, which heats the radiator from both the heat collecting surface and the radiation surface, and the heat transfer area when the high-temperature gas transfers heat to the radiator is enlarged. Since the hole reduces the development of the boundary layer and increases the heat transfer coefficient, the heat of the high-temperature gas is efficiently transmitted to the radiant surface, and the radiant energy is efficiently released from the radiant surface into the room to perform radiant heating. . On the other hand, by the draft action of the air in the heat shield space, a flow is created from the heat shield space inlet to the heat shield space outlet. Therefore, the temperature rise of the air in the heat shield space can be prevented, the heat conduction from the radiator heating air passage to the heat shield plate can be reduced, and the temperature inside the main body can be prevented from rising.

A heating device according to a third aspect of the present invention, in addition to the configuration of the first or second aspect, further includes a heat shield space surrounding the radiator heating air passage and having a heat shield space outlet adjacent to above the radiator. The heat collecting surface and the radiating surface are heated by the heat of the high-temperature gas generated by the high-temperature gas generating means, and the radiant energy is released from the radiating surface, so that the room is radiantly heated. I do. On the other hand, the radiator heating air passage is also heated by the high-temperature gas, and the air in the heat shielding space is heated. However, the air in the heat shield space rises and creates a flow from the heat shield space inlet to the heat shield space outlet. In addition, the high-temperature gas flowing out of the radiating surface heating air passage or the radiator hole becomes a strong updraft at the upper part of the radiator due to the draft action, but the air in the heat shield space near the outlet of the heat shield space above the radiator is ejected. Attract by effect. Therefore, a flow occurs from the heat shield space inlet to the heat shield space outlet, thereby preventing the temperature of the air in the heat shield space from rising. Therefore, heat conduction from the radiator heating air passage to the heat shield plate can be further reduced, and the temperature inside the main body can be prevented from rising.

According to a fourth aspect of the present invention, in addition to the configuration of the first, second, or third aspect, the heating apparatus surrounds the radiator heating air path and has a heat shielding space entrance below the radiator. With the configuration in which the heat shield plate forming the heat shield space is provided, the heat collecting surface and the radiation surface are heated, and the radiation surface emits radiant energy to radiantly heat the room.

On the other hand, the radiator heating air passage is also heated, and the air in the heat shielding space is heated. Then, cool air is introduced into the heat shield space from the heat shield space entrance below the radiator and creates a flow toward the heat shield space outlet by a draft action, thereby preventing a rise in the temperature of the air in the heat shield space.

It has a plate cooling air passage, and an outlet of the heat shielding plate cooling air passage is provided adjacent to a heat shielding space outlet. When the heating amount of the high-temperature gas generating means is large, the radiant body heating air passage is heated to a high temperature by the high-temperature gas, and heat energy is transmitted to the heat shield plate. However, in this configuration, it is possible to prevent the temperature inside the main body from increasing without reducing the amount of radiation by cooling the radiant body heating air passage without cooling the radiant body heating air flow, by flowing the wind generated by the cooling air blowing means to the heat shield plate. it can.

Further, the radiator heating air passage is heated by the high-temperature gas, and the temperature of the air in the heat shielding space is also increased. The air in the heat shield space rises and creates a flow from the heat shield space inlet to the heat shield space outlet. Then, the air in the heat shield space near the heat shield space outlet is attracted by the ejector effect of the cooling air flowing out from the outlet of the heat shield plate cooling air passage provided adjacent to the heat shield space outlet. Therefore, a flow occurs from the heat shield space inlet to the heat shield space outlet, and the temperature rise of the air in the heat shield space is further prevented, and the temperature inside the main body is prevented from rising.

According to a sixth aspect of the present invention, in the heating apparatus according to the first, second, third, fourth, and fifth aspects, the radiation rate of the heat shield plate is set to be smaller than that of the radiator heating air path. The radiator heating air passage is heated to a high temperature by the high-temperature gas and generates radiant energy when the high-temperature gas generating means has a large heating amount. However, since the emissivity of the heat shield is less than or equal to the radiator heating air path, the radiant energy is reflected and blocked by the heat shield. The generated radiant energy is reflected and transmitted between the radiator heating air passage and the heat shield plate, and is radiated indoors from the heat shield space entrance and the heat shield space outlet. Therefore, the temperature rise inside the main body can be suppressed, and the radiation generated in the radiator heating air passage can be effectively used for indoor heating.
