The present invention relates to a combustion chamber insulation structure of a hot air blower, and more particularly, a combustion hot air chamber main body of a portable hot air blower which is designed to easily perform hot air heating in various barns, rooms, and outside by using oil such as light oil or kerosene as fuel. By installing a heat insulator formed in the shape of a cylindrical container using a ceramic wool with far-infrared rays radiated inside, the heat loss caused by the heat in the combustion chamber body is transferred to the outer cylinder of the combustion chamber body and the user can burn the image due to the heating of the outer cylinder itself. Wear can be prevented in advance, and the odor generated by the combustion of oil at the initial ignition and smoke generation due to incomplete combustion can be effectively prevented, especially through the far-infrared rays generated from the heat insulation holes of ceramic wool. It can promote the metabolism of the human body and maximize the heating efficiency. The Rock is designed to dramatically improve the reliability of the product.

In general, as a portable hot air heater that can easily heat hot air in various barns, rooms, and outside by using light oil or kerosene as fuel, a number of prior applications such as Korean Utility Model Registration Application Nos. 97-11754, 11755, 11756, and 11757 have been made. have.

1 is a side view of the above-mentioned utility model registration application No. 97-11756, according to which the fuel tank (A1) for storing the fuel; A combustion chamber main body A2 installed above the fuel tank A1 and combusted by receiving fuel in the fuel tank A1 to generate fire power; A control unit A3 for manipulating ignition / extinguishing and operating time; An inlet port A4 formed on the rear surface of the combustion chamber body A2 and sucking outside air therein; A discharge port A5 formed at the front of the combustion chamber main body A2 and discharging the burned thermal power to the outside; It consists of an air bypass flow (A6) formed in the lower side wall of the said inlet port A4.

On the other hand, the combustion chamber body (A2) has a double structure consisting of the inner cylinder (A22) and the outer cylinder (A21) in order to prevent the internal heat from being transferred to the outside, the inner cylinder (A22) as described above In the case of forming only a double structure consisting of the outer cylinder and the outer cylinder A21, a portion of the heat generated by burning the oil by the burner is directly transmitted to the outer cylinder of the combustion chamber body. It can be blocked to some extent through the air layer, but the effect is so small that the external cylinder eventually has a problem that the heating is eventually heated.

Therefore, recently, in some hot air fans, there is a problem in heat collection because there is no heat insulating material in the space between the inner cylinder A22 and the outer cylinder A21, or heat insulation in the combustion chamber body is inserted into the space by inserting a heat insulating material such as glass fiber. Although it prevents leakage, in this case, it is very difficult to insert and install a heat insulating material such as glass fiber in the space formed between the inner cylinder and the outer cylinder, which not only increases the production cost of the product, but also uses the glass fiber itself as a heat insulating material. Since the material is very harmful to the human body, the worker is injured by the installation during the installation process of the heat insulating material, and there is a problem such that the heat insulating material acts as a factor causing environmental pollution when the hot air is disposed due to long-term use.

In addition, when the power switch is turned "off" to stop the use of the hot air fan, the fuel remaining in the oil supply pipe which delivers the fuel in the fuel tank to the fuel injection nozzle side is automatically discharged to the outside through the fuel injection nozzle to be made of a metal plate combustion chamber. This fuel is vaporized in the inner cylinder during the initial operation of the hot air fan after the liquid has accumulated inside the inner cylinder of the main body. Thus, when the oil accumulated in the inner cylinder is vaporized by the heat of combustion of the burner, the smell of incomplete combustion is generated, of course. Smoke caused by incomplete combustion is generated to contaminate the inside and outside air, and there is a problem that the oil accumulated in the combustion chamber body flows to the outside to contaminate the surroundings when the hot air is moved.

The present invention has been devised to solve such problems in the prior art by installing a thermal insulation hole formed into a cylindrical container shape by using an environmentally friendly ceramic wool as well as the radiation of far infrared rays in the combustion chamber body of the hot air blower. The heat in the combustion chamber body can be completely prevented from being transferred to the outer cylinder of the combustion chamber body, and the oil flowing through the fuel injection nozzle during the extinguishing is absorbed through the heat insulator and gradually evaporated when re-ignition, resulting in the combustion of the initial ignition oil. It can effectively prevent the generation of odor and smoke caused by incomplete combustion, and it can promote the metabolism of human body through far infrared rays generated from the insulator of ceramic wool, and greatly improve the reliability of the product by maximizing the heating efficiency. Providing the combustion chamber insulation of the hot air fan can be improved It is an object.

The present invention for achieving the above object, in the hot air fan composed of a fuel tank, a combustion chamber body having a burner and a blowing fan therein and a controller, a heat insulator having a shape of a cylindrical container is added to the interior of the combustion chamber body. It is characterized by the installation.

At this time, the heat insulator is characterized in that the molding process with a ceramic wool radiated far infrared rays during heating.

In addition, the bottom surface of the heat insulation is characterized in that the diffuser (Diffuser) installation hole is formed.

In addition, the combustion chamber body is characterized in that it is formed to have a double structure consisting of the inner cylinder and the outer cylinder.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the drawings.

Figure 2 shows an exploded perspective view of the hot air blower according to the present invention, Figure 3 shows an assembled perspective view of the hot air blower to which the present invention is applied, Figure 4 shows a side cross-sectional view of the hot air blower is insulated structure of the present invention. .

According to the present invention, the combustion tank body 2 and the controller 3 are provided with a fuel tank 1, a burner 4 and a blowing fan 5 therein, and a hot air outlet 2a is formed at the front portion thereof. In the configured hot air fan,

It is characterized in that the heat insulator 7 is added to the inside of the combustion chamber body (2).

At this time, the heat insulator 7 is characterized in that it is molded to have a cylindrical container shape by using a ceramic wool radiated far infrared rays during heating.

In addition, the bottom surface of the heat insulator 7 is characterized in that the diffuser mounting hole (7a) is formed.

In addition, the combustion chamber body (2) is characterized in that it is formed to have a double structure consisting of the inner cylinder 22 and the outer cylinder (21).

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, the hot air blower to which the heat insulation structure of the present invention is applied has a form mainly composed of a fuel tank 1, a combustion chamber body 2, and a controller 3.

At this time, the combustion chamber body (2) in the present invention by installing the heat insulating opening (7) in the interior of the combustion chamber body (2) itself may be formed as one outer cylinder, but if necessary to maximize the thermal insulation effect It is possible to have a double structure composed of the inner cylinder 22 and the outer cylinder 21 so that even some heat passing through the heat insulator 7 is not transmitted to the outside.

In addition, a burner 4 including a spark plug 8, a diffuser 11, and a fuel injection nozzle 12 and a blowing fan 5 are installed at a rear portion of the inner cylinder 22 of the combustion chamber body 2. The upper portion of the outer cylinder 21 is provided with a handle 9 for carrying, and the heat dissipation plate 6 and the protection net 10 is provided on the hot air outlet 2a side.

In addition, if necessary, blower fan 5a is further provided to blow air into the space formed between the outer cylinder 21 and the inner cylinder 22 to prevent the outer cylinder 21 from being heated by burner heat. May have

On the other hand, the main technical elements of the present invention, as described above, the heat insulator 7 is added to the interior of the combustion chamber body 2, the heat insulator 7 using a ceramic wool radiated far infrared rays during heating It is formed by molding to have a cylindrical container shape.

Accordingly, sparks generated by burning fuel in the burner 4 installed at the rear portion of the combustion chamber main body 2 may be injected toward the discharge port 2a of the combustion chamber main body 2 in response to the blowing of the blowing fan 5. When the hot heat generated inside the combustion chamber main body 2 is blocked by the heat insulator 7 so as not to be transmitted to the inner cylinder 22 and the outer cylinder 21 constituting the combustion chamber main body 2, the combustion chamber main body It is possible to prevent the loss of burns or heating heat that may be caused by the outside of (2) being heated by leakage and conductive heat.

In addition, since the heat insulator 7 is formed of ceramic wool in which far-infrared rays are radiated together with radiant heat during heating, heat generated by the combustion of fuel in the burner 4 is discharged through the discharge port 2a of the combustion chamber body 2. Far-infrared rays are radiated from the heat-insulating opening 7 formed by molding a ceramic wool having a state heated to a high temperature when discharged to a container shape, and discharged in a state contained in hot air.

Therefore, when there is a person in the room and the outside where the heating is performed by the heat containing the far infrared rays, the far infrared rays radiated from the heat insulator 7 and discharged to the outside with the heat penetrate deeply into the human body so that the biorhythm is activated and budded. As well as promoting metabolism, anion can be anionized by far-infrared rays, which not only maximizes heating efficiency but also significantly improves the reliability of the product.

At this time, the diffuser (11) is formed on the bottom surface of the heat insulator (7) to form a diffuser mounting hole (7a) is installed in the front of the burner (4) to rotate the air blowing through the blowing fan (5) The air generated by the burner 4 rotates through the diffuser 11 so that the flame of the burner 4 smoothly diffuses inside the combustion chamber body 2 and the heat insulating opening 7. It is dispersed in the front discharge port 2a side in a state.

In addition, the fuel remaining in the oil supply pipe which delivers the fuel in the fuel tank 1 to the fuel injection nozzle 12 by turning the power switch "off" to stop the use of the hot air blower through the fuel injection nozzle 12 When the fuel is automatically discharged into the furnace, the fuel is formed of ceramic wool before it reaches the inner cylinder 22 of the metal sheet, and flows down into the heat insulator 7 having its own pores and is absorbed.

Therefore, when the hot air is moved, the oil in the state absorbed by the heat insulator 7 does not flow to the outside to prevent contamination due to the oil, and the heat insulator 7 when re-ignition of the hot air in the future. As the oil permeated into itself gradually evaporates in response to the heating temperature of the oil, it can effectively block the generation of odor and smoke caused by the incomplete combustion of the oil flowing into the main body of the ignition chamber (2). It can be prevented in advance.

At this time, since the heat insulator 7 is formed of ceramic wool as described above, it does not cause any damage to the worker during the manufacture of the hot air blower, as well as the ceramic wool having environmentally friendly characteristics when the hot air blower is disposed of at the end of its life. There is no risk of contamination of the environment due to the insulation of the.

On the other hand, the heat insulating sphere 7 is formed of ceramic wool, but is not limited thereto. In addition, the heat insulating sphere 7 may be formed using a refractory brick material, and the like. The effect can be obtained.

Although the above-described embodiment has been described with respect to the most preferred embodiment of the present invention, it is not limited to the above embodiment, it will be apparent to those skilled in the art that various modifications are possible without departing from the technical spirit of the present invention.

As described in detail above, according to the present invention, a ceramic wool with far-infrared rays radiated when heated inside a combustion chamber main body of a hot air blower, which is configured to easily perform hot air heating in various barns, rooms, and outside by using light oil or kerosene as fuel. The additional installation of a cylindrical cylinder shaped insulator makes it possible to completely prevent the heat in the combustion chamber body from being transferred to the outer cylinder of the combustion chamber body, and secondly, the oil flowing through the fuel injection nozzle during the extinguishing is absorbed through the insulation hole. By slowly evaporating during re-ignition can effectively block the generation of odor and smoke due to incomplete combustion of oil during re-ignition, and thirdly, it can promote the metabolism of the human body through the far-infrared rays generated from the thermal insulation of the ceramic wool Can negatively ionize the air by the fifth, far infrared It is a very useful design that can not only maximize the heating efficiency but also significantly improve the reliability of the product.
