For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

Fig. 1 is a perspective view showing the external configuration of the harmonics heat fan 1 according to the present invention, Fig. 2 is a perspective view showing the configuration of the harmonics heat fan 1, Fig. 3 is an exploded view of the harmonics heat fan 1 Fig.

As shown in the drawings, the present invention includes a harmonic fan unit 1 including an outer housing 100 having a combustion chamber 140 and a heat exchange chamber 150 formed therein, A blower 300 disposed at one side of the flue 200 and forming a suction force to allow the outside air to flow into the outer housing 100 and to be moved; And a heat exchanging unit 500 provided in the heat exchange chamber 150 for exchanging heat between the combustion gas A1 of the combustion unit 400 and the heating air B.

The outer housing 100 houses the combustion chamber 140 and the heat exchange chamber 150 therein. 3, the heat exchange chamber 150 is divided into an upper heat exchange chamber 510 and a lower heat exchange chamber 520. The upper heat exchange chamber 510 is divided into an upper heat exchange space 512 and an intermediate heat exchange space 514 ). The upper heat exchange chamber 510 and the lower heat exchange chamber 520 are separated by the lower partitioning partition wall 521 and the upper heat exchange space 512 and the intermediate heat exchange space 514 are separated by the upper partitioning partition 513. [

Here, a space is formed between the outer housing 100 and the combustion chamber 140 and the heat exchange chamber 150. The spacing space defines a path through which the heated air introduced into the outer housing 100 is transferred to the heat exchange chamber (150). Since the spacing space is formed outside the combustion chamber 140, the heating air B flowing into the external air inlet 180 moves along the outer wall surface of the combustion chamber 140 and is preheated by the high temperature heat. Then, the air flows into the internal air inlet 190 of the heat exchange chamber 150.

Accordingly, the heating air B is heated before being introduced into the heat exchange chamber 150, heat exchange is performed in the heat exchange chamber 150 three times, and the heat is discharged to the outside, so that the heating efficiency can be maximized.

At this time, the combustion chamber 140 and the heat exchange chamber 150 are connected to each other by the lower communicating pipe 151. Thus, the hot combustion gas A1 and the flame burned in the combustion chamber 140 are moved to the heat exchange chamber 150 and heat-exchanged with the heating air B.

A fuel inlet door 110 is provided on the front surface of the outer housing 100 so as to be openable and closable. The user opens the fuel inlet door 110 to load the harmonious fuel on the upper combustion port 430.

An external air inflow hole (111) is formed through the fuel inlet door (110). The outside air introduced into the outside air inflow hole 111 is moved into the combustion chamber 140 and used for combustion of the harmonious fuel.

A control box 120 is provided below the fuel inlet door 110. The control box 120 may include a control board (not shown) and an input button (not shown) for driving the harmony fan 1.

The re-discharge door 130 is provided at the lower portion of the control box 120 so as to be openable and closable. The re-discharge door 130 is opened so that the user can discharge the combustion port 410 to the outside or discharge the re-release (not shown) to clean the ash produced after the combustion.

The re-discharge door 130 serves to supply the outside air into the combustion chamber 140 by the suction force of the blower 300. The re-discharge door 130 is openably and closably provided in the outer housing 100 as shown in FIG. A plurality of door air inflow holes 131 through which the outside air flows are formed on the outer wall surface of the re-discharge door 130 in different directions. When the blower 300 is operated, a negative pressure is formed and a negative pressure is formed in the heat exchange chamber 150 and the combustion chamber 140. The outside air is sucked in through the door air inflow hole 131 and is introduced.

The outside air introduced through the door air inflow hole 131 is moved through a door air flow path (not shown) formed inside the ash discharge door 130 and then supplied to the combustion chamber 140 through the air discharge pipe 132 . An air discharge pipe 132 protrudes toward the combustion chamber 140 on the inner wall surface of the ash discharge door 130.

4, the air discharge pipe 132 is disposed so as to communicate with the air inlet pipe 432 of the combustion port 430 when the ash discharge door 130 is closed to the outer housing 100, And is discharged to the air inlet pipe 432 side. Thereby, the outside air is used for the primary combustion of the harmonious fuel.

The flame 200 is disposed on the back surface of the outer housing 100. The flue 200 discharges the heating air (B) and the exhaust gas for which heat exchange is completed to the outside. A suction passage 210 for applying a suction pressure formed by driving the blower 300 to the heat exchange chamber 150 and the combustion chamber 140 is formed at a lower portion of the flue 200, .

The blower 300 is disposed in communication with the suction passage 210. The blower 300 forms a negative pressure by driving a blowing fan (not shown) provided therein to allow the outside air to flow into the combustion chamber 140 through the ash discharge door 130 and the control box (not shown). Further, the negative pressure allows the combustion gas generated by the combustion of the harmonics fuel in the combustion chamber 140 to be discharged into the flue 200.

The combustion unit 400 is provided in the combustion chamber 140 to induce complete combustion of the harmonious fuel. The combustion unit 400 includes a combustion port 430 in which the harmonious fuel M is loaded and the primary combustion and the secondary combustion of the harmonious fuel M progress together.

The combustion port 430 allows the primary combustion and the secondary combustion to proceed together. The combustion chamber 430 has an air inlet pipe 432 for receiving outside air from the ash discharge door 130 and a pair of spaced apart side walls of the combustion chamber 140, And an air branch pipe 431 for connecting the air inflow pipe 432 and the air discharge pipe 434. [

The air inlet pipe 432 is arranged to communicate with the air outlet pipe 434 of the ash discharge door 130 as shown in FIGS. 5 and 6, and receives the outside air. The air branch pipe 431 connects the air inlet pipe 432 and the pair of air outlet pipes 434. The air branch pipe 431 branches the outside air introduced through the air inflow pipe 432 and supplies the same amount to the pair of air discharge pipes 434.

The air discharge pipe 434 is formed in a hollow shape in which an air flow path 434a is formed. The upper surface of the air discharge pipe 434 forms an inclined surface 435 whose height decreases toward the center of the combustion chamber 140. A plurality of harmonized fuel M is loaded on the inclined surface 435 so that the freeze fuel M burned first under the bottom due to its own weight falls to the fuel loading plate 410 side by inclination of the inclined plane 435. [

The pair of air discharge pipes 434 are spaced apart from each other, and a fuel discharge hole 437 is formed at a predetermined size in the middle area. Thereby, the combusted harmonized fuel (M) first falls through the fuel discharge hole (437) to the fuel assembly plate (410).

A plurality of primary combustion air supply holes 435a for supplying the primary combustion air to the upper surface of the inclined surface 435 are formed at regular intervals.

Since the air discharge pipe 434 is formed so as to have a predetermined length in the direction of the inner side of the combustion chamber 140, the outside air A1 introduced from the ash discharge door 130 flows through the air inlet pipe 432 and the air branch pipe 431, And the lower air inflow pipe 432 and is heated by the flame generated by the primary combustion of the harmonious fuel M. [

As shown in FIG. 6, the hot air A2 is supplied to the flame and the combustion gas through the primary combustion air supply hole 435a so that the primary combustion of the harmful fuel M progresses.

On the other hand, a vertical surface 436 having a predetermined height is formed on a side surface of the air discharge pipe 434 forming the fuel discharge hole 437. Secondary combustion air supply holes 436a for discharging secondary combustion air toward the fuel discharge holes 437 are formed at regular intervals on the surface of the vertical surface 436.

The harmonics fuel M that has been primarily burned in the inclined plane 435 is burned from its lower portion due to its own weight and moves downward along the periphery of the fuel discharge hole 437. At this time, the secondary combustion air is supplied from the vertical surface 436 to the secondary combustion air A3. Secondary combustion air is discharged into the ventilated fuel M in a state of being heated hot by the flame generated by the primary combustion in the air discharge pipe 434.

As a result, the incompletely combusted harmonized fuel (M) is burned secondarily in the primary combustion and the complete combustion is induced. The completely burned flame and the combustion gas are transferred to the heat exchange unit 500 through the lower communicating pipe 151.

The heat exchange unit 500 is disposed in the heat exchange chamber 150 so that the heating air B and the combustion gas are in contact with each other to perform heat exchange. The heat exchange unit 500 according to the present invention proceeds with the primary heat exchange and the secondary heat exchange indirectly with the heating air B and the combustion gas and finally the tertiary heat exchange with the combustion gas and the direct flame. As a result, the heat exchange efficiency is high and the heating air is discharged to the outside in the hottest state.

The heating air B flows through the heating air inlet 180 of the outer housing 100 and flows into the inner air inlet 190 of the heat exchange chamber 150. The heating air B flowing into the inner air inlet 190 is transferred to the upper heat exchange chamber 510.

The heat exchange unit 500 is divided into an upper heat exchange chamber 510 and a lower heat exchange chamber 520. The upper heat exchange chamber 510 is divided into an upper heat exchange space 512 and an intermediate heat exchange space 514 by an upper partition 513. An upper combustion gas moving pipe 530 is disposed in the upper heat exchange space 512 and an intermediate combustion gas moving pipe 540 is disposed in the intermediate heat exchange space 514.

The heating air discharge pipe 550 is disposed in the lower heat exchange chamber 520.

Here, the heat exchange chamber 150 and the combustion chamber 140 are spaced apart from each other. Further, a space is also present between the heat exchange performance pipe 151 and the heat exchange chamber 150. 7 and 8, the high-temperature combustion gas and the flame transferred to the lower connection pipe 151 pass through the space between the outer housing 100 and the heat exchange chamber 150 where the heating gas outlet 170 is formed, And then flows into the intermediate heat exchange space 514.

At this time, the discharge end 553 of the heating air discharge pipe 550 is positioned by the path where the flame and the combustion gas are moved. Accordingly, the heating air discharged through the heating air discharge pipe 550 is finally brought into direct contact with the hot flames and the combustion gas discharged from the combustion chamber 140, and is heat-exchanged and discharged to the outside. As a result, the heating air B1 in the hottest state is exhausted to the outside, so that heat exchange efficiency can be improved.

The upper combustion gas moving pipe 530 and the intermediate combustion gas moving pipe 540 are arranged in parallel to the flue 200 in the combustion chamber 140, respectively. At this time, the direction of movement of the combustion gas A1 moved along the upper combustion gas moving pipe 530 and the direction of movement of the combustion gas A1 moved along the middle combustion gas moving pipe 540 are opposite.

7 and 8, the combustion gas passing through the lower combustion chamber 140 is moved to the intermediate combustion gas moving pipe 540 and then moved to the upper combustion gas moving pipe 530 in different directions.

At this time, since the upper heat exchange space 512 and the intermediate heat exchange space 514 are filled with the heating air B, the heating air B is moved along the upper combustion gas moving pipe 530 and the intermediate combustion gas moving pipe 540 Indirect heat exchange with the combustion gas proceeds.

Exhaust connection holes 516 and 517 are provided on both sides of the upper heat exchange space 512 and the intermediate heat exchange space 514, respectively. As a result, the combustion gas moving through the intermediate combustion gas moving pipe 540 is changed in direction and moved to the upper combustion gas moving pipe 530.

The operation process of the harmony heat fan 1 according to the present invention having such a configuration will be described with reference to FIGS. 7 to 9. FIG.

The fueled fuel is loaded on the inclined surface 435 of the combustion hole 430. The fuel is supplied to the lower portion through the fuel discharge hole 437 by its own weight in accordance with the combustion of the fuel and locally burning occurs so that even if a large amount of fuel is stacked on the inclined surface 435 at a time,

 Fueled fuel loaded on the inclined surface 435 is ignited, and the fuel inlet door 110 is closed. Then, the blower 300 operates according to the supply of power. As the blower 300 is driven, a suction pressure is formed, and outside air is introduced into the combustion chamber 140 from the re-discharge door 130 and the control box 120.

The outside air discharged through the door air discharge pipe 132a flows into the combustion hole 430 through the air inlet pipe 432. [ The outside air A1 flowing through the air inflow pipe 432 moves along the inside of the air discharge pipe 434 as shown in FIG. 5 and is discharged to the primary air supply hole 435a. The outside air A1 is supplied directly to the harmonious fuel M to be firstly combusted. The flame and the combustion gas generated by the primary combustion are moved downward.

At this time, the secondary air A3 discharged through the secondary combustion air supply hole 436a of the vertical surface 436 is moved along the inside of the air discharge pipe 434 and is contacted with the flame generated by the primary combustion, State, the incompletely combusted combustion gas in the primary combustion is supplied with the heated oxygen so that the combustion condition is satisfied and secondary combustion occurs.

The high-temperature flame and the combustion gas in which the secondary combustion is advanced move downward and flow into the heat exchange chamber 150 through the lower communicating pipe 151. The combustion gas is moved along the side space between the outer housing 100 and the heat exchange chamber 150 and then moved to the intermediate combustion gas moving pipe 540 through the second connection pipe 517. [ Then, the combustion gas A1 moved to the intermediate combustion gas moving pipe 540 is diverted in the first connecting pipe 516 and is transferred to the upper combustion gas moving pipe 530. Then, it is discharged to the outside through the flue 200.

8 and 9 are perspective views showing a movement path of the heating air B of the harmonics-warm air fan unit 1 according to the present invention.

When the combustion gas A1 is moved, the heating air B is introduced through the outside air inlet 180 of the outer housing 100 and then moved to the spacing space between the outer housing 100 and the combustion chamber 140 . And moves along the outer wall surface of the combustion chamber 140 along the spacing space to perform heat exchange in advance with the heat of the combustion chamber 140, so that the heating air is heated to a certain temperature. The heated air B is introduced into the upper heat exchange chamber 510 through the inner air inlet 190 of the upper heat exchange chamber 510. The heating air B is moved from the upper portion to the lower portion, and the combustion gas A1 moves from the lower portion to the upper portion. As a result, the heating air (B) moves downward, and gradually comes into contact with the hot combustion gas and the temperature rises gradually.

The heating air B undergoes primary heat exchange with the upper combustion gas moving pipe 530 in the upper heat exchange space 512 and secondary heat exchange with the intermediate combustion gas moving pipe 540 in the intermediate heat exchange space 514. Then, the refrigerant is moved to the lower heat exchange chamber 520 and then discharged to the heating air outlet 170 through the heating air discharge pipe 550.

Since the hot flame and the combustion gas directly discharged from the combustion chamber 140 are transferred to the space between the discharge end 553 of the heating air discharge pipe 550 and the heating air outlet 170, the heating air is directly contacted with the hot flame And the third heat exchange is performed.

As a result, the heating air is discharged into the room in a hot state. The heating air is circulated by convection in the room and then flows through the outside air inlet 180 again. In this way, since the heating air is circulated in the room, the heating efficiency of the room is increased.

As described above, the fire fighting fan according to the present invention advances combustion twice through the combustion holes provided in the combustion chamber, thereby inducing complete combustion, thereby minimizing the amount of heat energy lost.

Further, since the flame and the combustion gas generated by the complete combustion are discharged to the heat exchanger side and used for heat exchange of the outside air, the heating efficiency can be increased.

In addition, since the heat exchange between the combustion gas and the heating gas is performed three times in the heat exchange chamber, heat exchange efficiency of the heating air can be improved. Particularly, since the moving direction of the combustion gas and the moving direction of the heating gas are opposite to each other, the heating gas directly contacts with the hotest combustion gas immediately before the heating gas is discharged, and heat exchange is performed, thereby maximizing the heat exchange efficiency. Therefore, heating efficiency can be maximized even if wood fuel is used.

In addition, since incomplete gas is burned to induce complete combustion, it is possible to minimize the emission of pollutants by burning pollutants and energy by reducing energy consumption.

In addition, since the combustion is limited only in the combustion zone, unnecessary excessive combustion is prevented, and the fuel is lowered to the combustion chamber side due to its own weight, so that continuous combustion is possible.

The embodiment of the ventilation fan of the present invention described above is merely illustrative and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. There will be. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments.
