Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a combustion type radiant stove, and more particularly, to a combustion type radiant stove that performs radiant heating by radiation of far infrared rays.

[Conventional technology]

It is generally known that far infrared rays inherently have high thermal penetration (absorption) into objects, and that effective radiant heating can be achieved by applying far infrared radiation to radiant stoves. Combustion stoves that can uniformly radiate far infrared rays from the entire radiant surface and achieve high heating effects include those that use a catalytic combustion burner to radiate far infrared rays from the combustion surface. Ta.
(No literature available) [Problems that the invention aims to solve] However, when using a catalytic combustion burner, the catalyst itself is extremely expensive, which increases the cost of the stove, and it also requires a preheater. As a result, the control configuration and manual operations are complicated, and there is also a safety problem in that raw gas slip phenomenon tends to occur on the combustion side, making the combustion operation somewhat unstable.

An object of the present invention is to provide a combustion stove that has a rational configuration and can uniformly radiate heat by far-infrared radiation from the entire surface of the radiation surface without using a special burner such as a catalytic combustion burner.

[Means for solving problems]

The characteristic structure of the combustion type radiant stove according to the present invention is that a porous plate-like heat radiator coated with a far-infrared ray generating material and a porous plate-like member for regulating air are arranged vertically facing each other, and these heat radiators are disposed vertically facing each other. A burner is provided upwardly in a restricted space between the body and the perforated plate-like body for air conditioning, and a fan is provided to supply outside air to the restricted space through the perforated plate-like body for air conditioning. There is, and its actions and effects are as follows.

[Effect]

In other words, the high-temperature combustion gas generated by the burner is supplied by its natural upward flow to the restricted space between the porous plate-shaped thermal radiator and the air conditioning porous plate, and the supplied high-temperature combustion gas heats the thermal radiator. By doing so, far infrared rays are generated from the far infrared ray generating material coated on the heat radiator, and heat is radiated by far infrared radiation. By blowing and supplying it into the restricted space in a uniformly dispersed state through a shaped body,
By blowing the high-temperature combustion gas in the restricted space evenly over the entire back surface of the thermal radiator due to the back-up effect of the blown outside air, the thermal radiator can be heated evenly. Far-infrared rays can be emitted uniformly and effectively from the entire surface of the body.

[Effect of idea]

As a result of the above, although it is possible to obtain extremely high heating effects by making full use of the high heat penetration properties of far infrared rays, there is no need to use special burners such as catalytic combustion burners, and various types of general specification burners can be used. Because it can be applied, it can be made into an inexpensive stove, and since a preheater is not required, the control structure and operation form can be simplified, making it advantageous in terms of cost and operability. This also avoids the slip phenomenon, resulting in a stove with excellent safety.

〔Example〕

Next, an embodiment of the present invention will be described.

Figures 1 and 2 show the vertical cross-sectional structure and front structure of a combustion type radiant stove. A heat radiating plate 2 made of a ceramic lattice-like body is attached to the front opening of a casing 1 that is opened almost horizontally. is arranged in a vertical position so as to cover almost the entire surface of the opening, and the heat radiation plate 2 is baked and painted with far-infrared ray generating paint 3. On the other hand, a wire mesh 4 for regulating air is placed on the back side of the casing 1 to emit heat radiation. It is stretched in a vertical position facing the board 2.

Then, the bank burner 5 is installed in the lower part of the casing 1 so as to face upward with respect to the restricted space A formed between the heat radiator 2 and the air conditioning wire mesh 4 inside the casing 1. With,
A propeller fan 7 is installed in the casing 1 to blow air taken in from an intake port 6 formed on the back surface of the casing 1 into the restricted space A through the wind regulating wire mesh 4.
It is installed on the back of the .

8 in the figure is a heat insulating material facing the restricted space A,
Further, reference numeral 9 denotes an exhaust passage formed in the shape of a slit between the upper edge side and the lower edge side of the heat radiating plate 2 and the opening edge of the casing 1.

That is, the high-temperature combustion gas generated by the burner 5 is supplied to the restricted space A, and the heat radiation plate 2 is heated to a high temperature by the high-temperature combustion gas for heat radiation. By the back-up action of the outside air blown into the restricted space A in an evenly dispersed state, the high temperature combustion gas in the restricted space A is evenly blown onto the entire back surface of the thermal radiating plate 2. is heated uniformly, and by the uniform heating, far infrared rays are uniformly radiated from the entire heat radiation plate 2 coated with far infrared ray generating paint 3 toward the object to be heated.

[Another example]

As the porous plate-like heat radiating body 2 and the air conditioning porous plate-like body 4, porous plate-like bodies having various structures such as a lattice-like body, a mesh-like body, a punched plate body, a three-dimensional network structure, etc. can be applied. Moreover, various material configurations can be adopted for these materials, such as ceramics, metals, or a combination thereof.

Various materials and components can be used as the far-infrared generating material 3 to be coated on the thermal radiator 2, and the form of the coating treatment may vary depending on the generating material 3, such as baking painting, coating treatment, or simply pasting treatment. Various forms can be adopted.

The specific models of the burner 5 and the fan 7 do not matter.
