It is to be noted that like elements in the accompanying drawings use the same reference numerals in any of the drawings, and detailed descriptions of well-known functions or known configurations that may unnecessarily obscure the gist of the present invention are omitted. Come on.

As shown in FIGS. 1 to 4, the present invention includes a main body 1 having a front heat dissipation unit 1a having a reflection plate 101 installed therein so as to dissipate heat forward; A burner (2) installed inside the main body (1) for burning fuel to generate hot flame and combustion gas; A combustion chamber 3 in which a flame discharged from the burner 2 and combustion gas are blown into the inside, and on one side thereof, an opening and closing door 301 for discharging ash blown into the inside is formed; In order to dissipate the flame and the heat of the combustion gas blown into the combustion chamber 3 to the outside, one end is connected to the upper surface of the combustion chamber 3, the other end is a heat radiation connected to the exhaust 103 formed on the upper body (1) Tube 4; A pellet supply part for supplying wood pellets to the burner 2; It is composed of a blower forcibly blown so that hot air is discharged through the heat dissipation unit (1a) will be described in more detail the main components.

The main body 1 of the present invention forms a heat dissipation unit 1a having a reflection plate 101 installed therein to dissipate heat to the front, and a safety grill net 102 is installed on the front side of the heat dissipation unit 1a.

In addition, the main body 1 is provided with a control panel 104 for controlling the operation of the heater and displaying the operation state on one side of the front surface, and the user can easily control the operation of the heater and at the same time control the operation state of the heater. You can easily check through the various display windows installed in the).

The burner 2 of the present invention is installed at one inner side of the main body 1 so as to communicate with one end of the combustion chamber 3 formed under the heat dissipating portion 1a of the main body 1, so that the burner 2 has a high temperature. Flame and combustion gas are discharged directly to the combustion chamber (3).

On the other hand, the upper portion of the burner (2) is formed with an injection unit 201 is injected into the wood pellets supplied through the pellet supply pipe 505, the lower portion is loaded with a wood pellet loaded through the input unit 201 ( 202 is formed, and one side of the loading part 202 is composed of an ignition device 203 for igniting wood pellets loaded on the loading part 202 to generate a high temperature flame and combustion gas.

In this case, it is preferable that the inlet 201 forms a flange to enable close connection with the pellet supply pipe 505.

In addition, the loading portion 202 on which the wood pellets are loaded is concave with a porous plate made of metal so that the wood pellets loaded can be ignited by the ignition device 203 to enable smooth combustion of the wood pellets when a flame and combustion gas are generated. It would be desirable to form the same.

The combustion chamber 3 of the present invention is preferably made of a heat-resistant metal to withstand high temperatures because the flame and the combustion gas discharged from the burner 2 are ejected to the inside, and the combustion gas in the process of ejecting the combustion gas into the combustion chamber 3. It may be desirable to form an opening and closing door 301 on one side of the combustion chamber 3 so that the ash discharged together with the ash accumulated in the combustion chamber 3 can be easily processed.

The heat dissipation pipe 4 of the present invention is connected to the upper surface of the combustion chamber 3, one end is connected to the upper surface of the combustion chamber 3 in order to heat the flame and the heat of the combustion gas emitted to the combustion chamber 3 to the outside, the other end is formed on the upper body (1) It is connected with the exhaust part 103.

Therefore, the high-temperature flame and the combustion gas ejected into the combustion chamber 3 by the burner 2 are heated on the outer surface of the heating tube by heating the entire heat radiating tube 4 to a high temperature via the zig-zag of the heat radiating tube 4. A large amount of far infrared is emitted from the coated far infrared radioactive ceramic coating layer.

In addition, fine particles of wood pellets, which are unburned in the process of blowing high-temperature flame and combustion gas from the burner 2 into the combustion chamber 3, are also burned at a high temperature in the process of passing the flame and combustion gas through the arc radiating pipe 4. Since secondary combustion is performed by the heated arc radiator 4, it is possible to prevent the discharge of the unburned wood pellets and the like from being discharged through the exhaust section 103 as the heat generation amount is increased and clean exhaust gas is discharged. This is done.

In addition, by installing the exhaust motor 103a in the exhaust part 103, it is possible to forcibly exhaust the exhaust gas discharged through the heat dissipation tube 4, thereby improving the exhaust gas discharge efficiency.

The pellet supply unit of the present invention is provided with a pellet loading box 501 installed at the rear of the main body 1 with a lid 501a at the top, and a transfer screw 503 driven by the pellet transfer motor 504 to pellet loading. (501) a pellet discharge pipe 502 for discharging the pellets to the outside, and a pellet supply pipe 505 for supplying the pellets discharged to the pellet discharge pipe 502 to the burner (2) installed inside the main body (1). .

At this time, the pellet loading box 501 forms a large inner space for storing a large amount of wood pellets at once, and it may be preferable to install a lid 501a on the upper portion so as to easily fill the wood pellets therein.

In addition, the pellet discharge pipe 502 is installed obliquely on one side of the pellet loading box 501 so that the lower end is close to the bottom surface of the pellet loading box 501, the upper end is located outside one side of the pellet loading box 501. It is installed through one wall of the pellet loading box 501.

At this time, the pellet discharge pipe 502 is installed inside the pellet screw discharge pipe 503 is driven by the pellet feed motor 504 installed on the outer end of the pellet discharge pipe 502, the pellet filled in the pellet container 501 pellet discharge pipe 502 is used to discharge the wood pellets to the outside.

The wood pellets discharged to the outside of the pellet discharge pipe 502 by the transfer screw 503 are transferred to the burner 2 by the pellet supply pipe 505 connected between the pellet discharge pipe 502 and the inlet 201 of the burner 2. By being supplied, combustion by the burner 2 can be made.

The blower of the present invention is provided with a blower 601 on the outer surface of the main body 1, and forms a space 105 between the main wall and the reflecting plate 101 of the main body 1, thereby providing a space between the main wall and the reflecting plate 101. The inside of the 105 is heated by the far infrared rays and the heat radiated from the heat radiating tube 4.

At this time, when the external air is forcedly blown to the space portion 105 between the circumferential wall and the reflecting plate 101 by using the blower 601, the air heated in the space portion 105 is forced to be blown by the blower 601. Is forced into the front of the main body 1 through the exhaust hole 101a formed in the reflecting plate 101, so that not only the far infrared rays emitted from the heat radiating tube 4 but also the front of the heat radiating part 1a through the exhaust hole 101a. Heating efficiency is improved by the hot air through which forced air is blown.
