The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like parts are designated with like reference numerals throughout the specification.

FIG. 1 is an exploded perspective view showing a fireplace according to a first embodiment of the present invention, FIG. 2 is an assembled perspective view illustrating a fireplace according to a first embodiment, FIG. 3 is a view showing a fireplace according to the first embodiment Sectional view.

As shown in the figures, the furnace 1 according to the first embodiment of the present invention includes a main body 10, a heat-resistant tube 100, a heating portion 20, a lid 30, .

The main body 10 may be formed in any one of circular, elliptical, and polygonal shapes having an open top and a combustion chamber 11 space in which the burned object is burnt. Are formed in a cylindrical shape. The fuel to be combusted may be selectively used fuel such as firewood or lignite.

The heat-resistant tube 100 is accommodated in the combustion chamber 11 of the main body 10, and has an upper and a lower surface opened and formed into an empty pipe shape therein. The heat-resistant tube 100 is formed to have a diameter smaller than the diameter of the main body 10 and is accommodated in the combustion chamber 11 of the main body 10 and is placed on the bottom of the main body 10, And protects the main body 10 from flames or the like. The heat-resistant pipe 100 is made of steel or stainless steel and is disposed around the lower end of the air supply pipe 40, which is the highest temperature portion in the combustion chamber 11 of the main body 10, It is prevented that the opening or flame is directly transmitted to the main body 10, so that the main body 10 is prevented from being corroded and the durability is not deteriorated. The heat-resistant tube 100 can be easily replaced with a new heat-resistant tube 100 when the heat-resistant tube 100 is worn by continuous use. The heat-resisting tube 100 described above can also be made of a thin steel plate. In this case, the heat-resisting tube 100 can be subjected to beading treatment to improve rigidity. In addition, in the first embodiment, the heat-resistant tube 100 can be made shorter than the height of the main body 10 by about 1/2. If the length of the heat-resistant pipe 100 is longer than 1/2 of the height of the main body 10, the durability of the main body 10 is increased. However, the space of the combustion chamber 11 may be reduced to reduce the burning time There is a disadvantage in that the relative cost is increased. If the heat-resistant tube 100 is shorter than 1/2 of the height of the body, the durability of the body is not greatly increased.

The furnace 1 according to the first embodiment of the present invention has a triple structure by the main body 10, the heat-resistant tube 100 and the heat-generating portion 20 described later and has a heat insulating effect and a warming effect on the combustion chamber 11 As the temperature is increased, the efficiency of combustion due to the high temperature combustion can be provided. In addition, when corrosion occurs in the main body 10, it is possible to prevent the heat of the combustion chamber 11 from being immediately discharged through the corrosion-generated portion to the communication pipe 60, The furnace 1 can prevent the main body 10 from being corroded and allow the heat to stay in the heating part for a long time through the upper part of the combustion chamber 11 so that the heating effect of the heating part 20 is not reduced .

The lid part 30 hermetically closes the opening 21 formed in the upper part of the heat generating part 20 so as to prevent the heat of combustion from escaping to the outside of the combustion chamber 11. The lid part 30 is simply placed on the upper surface of the heat generating part 20 The heat generating part 20 can be easily opened and closed by being coupled with the upper surface of the heat generating part 20 by bolts, mica rings, or the like. At one side of the lid part 30, a charging port 31 having a predetermined diameter is formed through the upper surface. Fuel can be injected into the combustion chamber 11 through the injection port 31. [ It is possible to prevent the heat of combustion of the combustion chamber 11 from escaping directly to the outside after covering the cap 50 with the charging port 31 after the fuel is completely charged into the combustion chamber 11. [ In the lid part 30, at least one installation hole 32 is formed to pass through the upper surface of the lid part 30 in order to install a power supply pipe 40 to be described later.

The air supply unit 40 is provided for guiding the air preheating function and the complete combustion of the object to be combusted and the upper side thereof is installed in the installation hole 32 of the lid part 30 and the lower part thereof is accommodated in the combustion chamber 11 . It is preferable that the air intake pipe 40 is applied to two or more so as to increase the surface area to double the effect of preheating the outside air to improve the combustion efficiency. The outside air is supplied to the combustion chamber 11 through the internal passage 42 of the air supply tube 40 as the upper open portion of the air supply tube 40 is exposed to the outside. The outside air is heated to the high temperature in the combustion chamber 11 and the combustion heat generated by the combustion of the material to be burned in the course of passing through the air intake tube 40. As the air is supplied to the combustion chamber 11 in such a heated state, The contact is smooth and the combustible is completely burned. As a result, the heat generation rate of the heat generating portion 20 is improved and the thermal power can be lowered, so that the amount of the material to be burned can be reduced. The air supply unit 40 may be installed in the lid 30 so as to further improve the complete combustion of the object to be combusted. In this case, So as to improve the complete combustion rate. A supply hole 41 connecting the passage 42 and the combustion chamber 11 may be formed in the engine 40. The supply holes 41 may be formed at intervals in the longitudinal direction and the circumferential direction of the air supply pipe 40.

On the upper surface of the lid part 30, a regulating part 90 is provided so as to be close to the opening of the air supply tube 40 and to adjust the opening area of the air supply tube 40. The regulating unit 90 can regulate the amount of air supplied to the combustion chamber 11 through the air supply pipe 40. The regulating unit 90 is rotatably installed along the upper surface of the lid 30 through the pivot 120 and is formed to have a wider diameter than the lid 30 so that the upper surface of the lid 30 It is possible to block the entire upper end of the air supply tube 40 or to open only a part thereof. The amount of outside air to be supplied to the combustion chamber 11 can be selectively controlled by freely adjusting the top opening area of the air intake 40 in accordance with the rotation angle of the control unit 90.

When the lid 30 is located on the opposite side of the communication port 60, the power supply suction force to the combustion chamber 11 is maximized due to a strong smoke discharge power and the closer to the communication port 60, The weaker the suction power is, the weaker the thermal power, but it is helpful to increase the burning time. The air supply pipe 40 is set to a corresponding length so that the air can be preheated while passing through the air supply pipe 40 and the upward flow of the combustion chamber 11 does not interfere with the downward supply of the combustion chamber 11. [ When the lower end of the air supply pipe 40 is spaced from the ash pipe 130 by 5 cm or more, the lower end of the opened air supply pipe 40 is closed and finely drilled as much as the area of the air supply pipe 40, Thereby minimizing the influence on the downward supply airflow.

Meanwhile, a bead protruding outward is inserted into the ceiling of the heat-resistant pipe 100 to process the ash and charcoal generated by the combustion of the material to be burned, and the ashtray 130 is detachably installed between the beads, Can be obtained. 3, the inner surface of the heat-resistant tube 100 is protruded outwardly through a beading process to form a groove 101. The groove 101 is formed in the end portion of the ash- It is possible to install the ash tray 130 in the heat-resistant tube 100. [ When the ashtray 130 is installed, the ash and char is separated under the ash tray 130 by the gravity, so that the contact area of the outer periphery of the combusted material is widened, and the combustion activity becomes more active, so that a stronger firepower can be obtained. When the auxiliary combustion tube 140 described later is used, the ash receiver 130 is required as a cradle of the auxiliary combustion tube 140.

In addition, when the ash combustor 130 is not provided, the burned material is buried in the ash and charcoal so that the contact area with the external air supply is reduced, and the burning time is increased while the burning time is increased. have.

As shown in FIG. 1, the ashtray 130 is not formed in the same shape as the main body 10 but is installed to avoid the lower end of the air supply tube 40 having the highest temperature to prevent corrosion of the ashtring 130 A rectangular grill shape having a width smaller than the diameter of the auxiliary combustion tube 140 and a distance between the two air intake pipes 40 to be described later, is made of a stainless steel pipe to prevent deformation and increase durability, And is installed over the intermediate bead portion of the heat-resistant pipe (100) so that the external combustion air can be smoothened even when using the auxiliary combustion pipe (140) 10, it is not necessary to construct the pedestal of the ashtray for securing the storage space of the ash and the charcoal, which is lighter and the production cost is reduced. On the other hand, when the ashtray 130 is formed in a rectangular shape such as an ellipse or a rectangle, it can be adjusted so that the ashtring is not located at a position near the lower end of the airtightest engine with the highest temperature. Therefore, it is possible to prevent corrosion by the heat of the ashtray, and even if it is formed into a rectangular shape, the effect of isolating the object to be burned from the charcoal and ash is sufficient.

As shown in FIG. 1, the auxiliary combustion pipe 140 may be formed in a pipe shape having an open top and a downside, and a flange 142 extending outwardly from the bottom end may be formed. A handle 143 may further be formed to protrude from the bottom surface of the flange 142. The knobs 143 can be attached at four positions at an angle of 90 degrees to enhance the convenience of operation when the auxiliary combustion tube 140 is installed or recalled. When the handle 143 is mounted on the ashtray 130, the handle 143 is positioned at a position where there is no through hole or ashtray of the ashtray 130, or the handle 143 is brought into contact with the upper surface of the ashtrap 130, The height of the auxiliary combustion tube 140 can be adjusted by the height of the ashtray 130 and a safety device can be added by a hanger (not shown) for stability of the auxiliary combustion tube 140. And the material to be burned is combusted inside the auxiliary combustion tube (140).

The heat generating unit 20 is a heat dissipating unit for dissipating the heat of combustion in the main body 10 to the outside so that the upper part of the main body 10 is opened and a hollow space is formed therein, have.

The heating unit 20 is not necessarily formed in the same shape as the main body 10 but has a corresponding size to accommodate the main body 10 therein so that the heating unit 20 and the main body 10 10, a hollow space is formed. Since the space between the heating unit 20 and the main body 10 serves as an air layer, the temperature of the combustion chamber 11 is maintained at a high temperature . In addition, since the combustion heat is stored in the air layer and the combustion heat is indirectly radiated through the heat generating portion 20, the heat of combustion exiting the communication portion 60 can be minimized. In addition, the heat generating unit 20 can improve the heat insulation and heat insulation effect of the main body 10 due to the indirect heat generation through the heat of combustion in the main body 10. [ As a result, the temperature of the combustion chamber 11 becomes high and it can be satisfied almost completely.

In addition, since the bottom surface of the heat generating portion 20 is subjected to castable molding or adiabatic treatment with pearlite or the like, the heat insulating effect is improved. Therefore, even if the bottom surface of the heat generating portion 20 is placed on the ground without a pedestal (not shown) Can be prevented from being pulled to the ground.

The first smoke outlet 22 and the second smoke outlet 23 are formed on one side surface of the heat generating portion 20 and spaced apart from each other by a predetermined distance in the vertical direction, 22 and the second smoke outlet 23 are provided with a communication hole 60 so that the smoke in the heat generating portion 20 and the main body 10 can be easily discharged to the outside.

The communication portion 60 includes an upper portion tube 61 bent substantially horizontally in the direction of the heat generating portion 20 and passing through the first smoke outlet 22 and the second smoke outlet 23, And a lower portion engine 62. A first gap 60b is formed in the upper portion of the communication tube 60 and a second gap 60a is formed in the upper portion tube 61. [ The first damper 70b and the second damper 70a can be selectively inserted or drawn into the communication hole 60 through the first gap 60b and the second gap 60a. The first damper 70b and the second damper 70a are formed in a substantially semicircular shape so as to be easily inserted into the first gap 60b and the second gap 60a, A handle protruding out of the housing 60 is formed. When the first damper 70b is pulled out of the first gap 60b of the communication hole 60 and the second damper 70a is pulled out of the second gap 60a to open the inside of the communication hole 60, The air and smoke of the air outlet 11 are discharged quickly through the first smoke outlet 22 instead of the second air outlet 23 having a long path and a smoke load, It can be sucked. Therefore, the ignition of the object to be burned is facilitated and the heat is released through the lid 30 due to the strong thermal power due to the smooth combustion. However, since the side of the heat source 1 is relatively hot, It can be used effectively when it is used as a fireplace in a place requiring a heating effect by thermal convection such as a vinyl house, a workshop, a workshop, and in a summer season. In particular, the cooking utensil can be easily heated by placing a cooking vessel such as a pot on the upper portion of the inlet 31 after removing the cap 50 from the lid 30 described later. When the second damper 70a is inserted into the second gap 60a and the inside of the communication hole 60 is closed, the space between the inner body 10 and the heat generating portion 20 and the second And is discharged through the communication hole 60 through the smoke outlet 23. In this case, as compared with the case where the heat is discharged through the second smoke discharge port 23 and the communication pipe 60, the heating efficiency is improved as the discharge path of the heat is longer, so that a wider area can be warmed in outdoor use. The second damper 70a is inclined to the upper part orifice 61 and can be fixed to the upper part orifice 61 by friction with the second part damper 70a so that the inside of the upper part orifice 61 can be partly opened or closed . The first damper 70b is inserted into or drawn out from the first gap 60b to open or close the communication hole 60 to control the flow of the smoke. The second gap 60a and the second damper 70a may be omitted from the first smoke outlet 22 or the second smoke outlet 23 formed in the middle portion of the heat generating portion 20. In this case, can do.

Meanwhile, the main body 10 may be seated through the air layer forming portion 80 when the main body 10 is disposed on the bottom surface of the heat generating portion 20. The air layer forming part 80 is formed in a block or pipe shape so that the main body 10 is spaced apart from the bottom surface of the heat generating part 20 by a predetermined interval. The air layer forming portion 80 may be integrally formed with the heat generating portion 20 or may be integrally formed with the main body 10. [ The combustion heat in the main body 10 is not conducted directly to the heat generating portion 20 due to the air layer forming portion 80. Therefore, even if the heat generating unit 20 is directly placed on the ground without a separate pedestal (not shown), the heat transfer between the main body 10 and the heat generating unit 20 can be minimized, . The air layer forming unit 80 may be omitted when the bottom surface of the heat generating unit 20 is castable or heat-treated with pearlite.

The cap 50 is removed from the lid 30 and the first damper 70b is removed from the first A cylindrical heat concentrating tube 110 is formed on the upper surface of the lid 30 by completely inserting it into the gap 60b to close the entirety of the communication hole 60 and to open the upper and lower surfaces, The supplementary combustion tube 140 can be additionally provided on the ashtray 130 which is placed on the heat-resistant tube 100 which is seated on the bottom of the main body 10. At this time, the heat concentrating tube 110 is seated on the edge surface of the inlet 31 of the upper surface of the lid 30, and the inside of the combustion chamber 11, the inlet 31 and the heat concentrating tube 110 are connected The ascending air current which is strengthened due to the communication effect of the auxiliary combustion tube 140 and the concentration of the ignition point is increased as the inside of the communication hole 60 is closed by the first damper 70b, (Not shown) is installed at a lower portion and a middle portion of the heat concentrating pipe 110 with a predetermined interval, and is discharged through the inlet port 31 and the heat concentrating pipe 110 without being discharged through the communication pipe 60. [ Lt; / RTI >

5 is a sectional view of a fireplace according to a third embodiment of the present invention. As shown in FIG. 5, a pipe-shaped auxiliary combustion pipe 140 having an upper end and a lower end opened on the ashtray 130 may be additionally provided. That is, when the fire or lignite is injected into the auxiliary combustion pipe 140 and then ignited, the outside air is transferred to the combustion chamber 11 through the inside of the air supply duct 40, Or the lignite disposed in the auxiliary combustion tube 140 through the perforated hole 141 with the upper and lower sides and the left and right spaced apart from each other at a predetermined interval or through the perforation hole 131 of the ash tray 130 And is then raised against the bottom surface of the main body 10 to be supplied to the bottom of the ash 130 through the perforation hole 131 of the ash receiving unit 130 and to the fallow or lignite located in the inside of the auxiliary combustion pipe 140 The combustion efficiency is improved.

In addition, when the auxiliary combustion tube 140 is installed in the combustion chamber 11, the space in the combustion chamber 11 is reduced, so that even with a small amount of recirculation, the combustion effect becomes close to the complete combustion condition depending on the effect of concentration, The heat efficiency is increased and the burning time is increased compared with the amount of fuel. Therefore, it can be usefully used in summer rainy season and during the heat. When the furnace is used, the heat can be guided to the object to be heated. ) Is inserted into the inlet (31), the triple pocket stove becomes relatively high, but the maximum heating power is released to enlarge the calorific value range of the hearth, and the fuel such as lignite can be burned easily Help. At this time, the heat-resistant pipe 100 must be installed since heat corrosion of the main body is a concern due to a strong thermal power.

Meanwhile, when the lid 50 is covered on the upper end of the auxiliary combustion pipe 140 when using the triple pocket stove 140, it is possible to prevent the smoke flowing backward intermittently and to open and close the regulating portion 90 of the installation hole 32, It is possible to adjust the finishing power more finely together with the adjusting part 90 of the mounting hole 32 when the air supply adjusting part 90 fixed by the turning shaft 120 is installed on the lid 50. [

The plurality of perforation holes 141 are spaced apart from each other with a predetermined interval along the side surface of the auxiliary combustion tube 140 so that the three-pocketed stove can be used as a backfire microstructure that rises on the inner wall of the auxiliary combustion tube 140 It is returned to the combustion chamber together with the additional supply air to be combusted, thereby improving the combustion efficiency. Also, when the furnace is used as a furnace, air can be smoothly supplied into the auxiliary combustion tube 140 even when the amount of char under the auxiliary combustion tube 140 is limited due to accumulated char, and the remaining space of the combustion chamber 11 becomes an air tank, Air can be supplied

On the other hand, the heat guided to the immediate lower portion of the inlet 31 due to the auxiliary combustion tube 140 mounted on the ash tray 130 opens the stopper 50 to heat the object such as a pot. The height of the auxiliary combustion tube 140 is preferably set so as to be spaced apart from the charging port 31 by about 5 cm. The distance between the inlet 31 and the upper end of the auxiliary combustion tube 140 must be 5 cm or more so as to be smoothly discharged to the communication, so that the height of the auxiliary combustion tube and the beading position of the heat-resistant tube are determined.

As shown in FIG. 5, the auxiliary combustion tube 140 may further include a flange 142 formed to extend outward at the lower end thereof. A handle (143 in Fig. 3) may be additionally formed to protrude from the bottom surface of the flange 142. The handle (143 in FIG. 3) can be attached at four positions at an angle of 90 degrees, thereby improving the operational convenience when installing or recovering the auxiliary combustion tube 140. The handle may be inserted into the through hole of the ashtray 130 when placed on the ashtray 130 or may be mounted on the ashtray 130 to adjust the height of the auxiliary combustiontank 140. [ When the auxiliary combustion tube 140 is disposed close to the inlet 31 by the height of the handle when used as an oven, the heat is directly discharged to the outside through the inlet 31, so that a stronger thermal power can be obtained. This is because the auxiliary combustion tube 140 is installed in the ashtray 130 spanning the heat-resistant tube 100, and when the fire point is at the bottom as in the initial ignition, it burns upside down like a triple pocket stove, It is preferable to use a TLUD (Top Light Up Draft) method by placing a fire fighter at the top of the auxiliary combustion pipe from the beginning. At this time, if the inlet 31 is opened with the first damper 70b closed, the contact area between the cold outside air and the hot ascending air stream of the combustion chamber is widened and there is a phenomenon of pushing and pulling each other. At this time, by placing the handle on the upper surface of the ash receiving member 130, the contact area is narrowed by the height of the handle, and the upward air flow force closer to the inlet 31 is strengthened so that the flame easily reaches the center of the inlet 31, ) Because the cool outside air is supplied to the combustion chamber on the outside, the passages of the outside air and the ascending air are separated from each other. As described above, if the upper end of the auxiliary combustion tube 140 is located 5 cm below the injection port 31, the height of the handle is preferably set to about 3 cm.

In addition to the second damper 70a provided in the first smoke outlet 22, the first damper 70b capable of opening and closing the entire interior of the communication hole 60 is used to close the inside of the communication hole 60 The flame and the heat discharged through the main body 10 through the communicating tube 60 pass through the inlet 31 to the outside of the lid 30 through the auxiliary combustion tube 140 in the combustion chamber 11, .

With this principle, when the oven (trivet) is placed on the lid 30 and the cooking vessel is placed on the trivet, the flame and the heat are directly transmitted, so that the highest thermal power necessary for cooking can be obtained.

If the opening and closing of the first damper 70b is about half, the fire power can be finely adjusted together with the adjustment of the injection amount of the firewood and the supply amount by means of a heavy blow if the first damper 70b is fully opened, If you place a cooking vessel on top of it and put it on a small fire or ode (not in the city), you can control the ideal firepower as a fireplace in a keep-warm mode.

The flange 142 formed at the end of the auxiliary combustion tube 140 has an inner diameter equal to the outer diameter of the auxiliary combustion tube 140 and an outer diameter of which is smaller than that of the ash 130, As shown in Fig. The flange 142 can prevent deformation of the auxiliary combustion tube 140 due to the high temperature combustion of the object to be combusted and widen the contact area with the ash receptacle 130 to seat the ashtray 30 more securely, When the stove is used, the auxiliary combustion tube 140 can be easily spread on the lid 30 at the inlet 31. A separate reinforcing member may be rounded and welded on the upper end of the auxiliary combustion tube 140 along the inner circumference to prevent deformation and enhance durability.

Meanwhile, in the stove according to the present invention, smoking and cooking can be progressed step by step using the first damper 70b capable of adjusting the direction of firepower and flame as described above. That is, after the burned object is ignited in the auxiliary combustion tube 140 and the thermal power is activated, the smoke is injected into the quartz or wet oak piece, and then the inside of the communication hole 60 is closed with the first damper 70b The smoke generated in the softened spinning material flows out through the inlet 31 to smell the smell of the food, and the first damper 70b is opened And the smoke is discharged into the communication, it becomes possible to switch to a very pleasant cooking environment without smoke and without fire.

If the first damper is closed without the auxiliary combustion tube 140, if the inlet 31 is not opened, the smoke may escape into various gaps and gradually lose the thermal power. Even when the inlet 31 is opened, It is preferable that the auxiliary combustion tube 140 is installed in the combustion chamber when the furnace or the firewood is used for baking firewood.

5, the lid 30 may further include an auxiliary supply hole 32 and an auxiliary supply portion 33. [ It is possible to supplement the additional supply air only by the auxiliary supply air holes 32. However, since the auxiliary air supply unit 33 serves as an air tank, the combustion efficiency can be improved by performing the preheat supply. The auxiliary air holes are formed through the lid portion 30 corresponding to the combustion chamber 11 side of the upper end of the main body 10. The auxiliary air holes 32 may be disposed in a path extending from the combustion chamber 11 to the heat generating portion 20. The opening degree of the auxiliary air hole 32 can be adjusted by adding an unillustrated air supply adjusting unit. This makes it possible to provide more stable heating power and control. Further, when the auxiliary combustion pipe 140 is used, additional air supply is smooth. Two or more auxiliary supply parts (33) may be provided to efficiently burn the combustible having a low flash point. A plurality of auxiliary air supply holes 32 connected to the combustion chamber 11 may be formed at intervals in the lid 30 and an auxiliary air supply unit 33 may be installed at a lower end of the auxiliary supply air holes 32 . The auxiliary supply portion 33 is formed in the shape of a square pipe and a side surface is coupled to the lower end of the auxiliary supply hole 32 and a connection hole 33a having the same size as the auxiliary supply hole 32 is formed at a position where the auxiliary supply portion 33 is coupled. It is preferable that a plurality of through holes 33b are formed on the side surface for supplying air. The auxiliary air supply part 33 is located on the vertical line with the combustion chamber 11 when the opening part 21 of the heat generating part 20 is closed by the lid part 30 and the outside air passes through the through hole 32 of the lid part 30 And the supply hole 101 of the auxiliary supply part 100 and is supplied to the combustion chamber 11. The amount of outside air supplied to the combustion chamber 11 becomes richer as the air preheated through the air supply unit 40 and the auxiliary supply unit 33 is supplied to the combustion chamber 11, Waste such as agricultural by-products such as rice straw having a low flash point and corrugated board can be easily burned as they are continuously supplied to the combustion chamber 11 through the burner 33. When the main air unit 40 is closed or opened at the minimum, 33) is increased, overheating can be prevented. On the other hand, in the case of applying the auxiliary supply portion 33, the supply hole 41 of the air supply unit 40 may be omitted.

6 to 8 are views showing a stove according to a fourth embodiment of the present invention. The furnace according to the fourth embodiment includes a main body 1100, a heat generating portion 1200, an auxiliary combustion tube 1400, and a heat concentrating tube 1600. As shown in the drawings, the heating unit 1200 according to the fourth embodiment is disposed above the main body 1100, unlike the first to third embodiments. That is, it can be used only as an oven without the heat generating part 1200 and the heat concentrating tube 1600, and becomes a hearth without communication when the heat concentrating tube 1600 and the heat generating part 1200 are installed

The main body 1100 is formed in a pipe shape in which the upper end and the lower end are clogged. A first opening 1121 is formed in an upper surface 1120 of the main body 1100. A main body inlet 1110 is formed in an area below the side surface of the main body 1100 and the main body inlet 1110 is opened and closed by the main body door 1111. The amount of supply to the main body 1100 can be adjusted according to the degree of opening and closing of the door 1111 and the through hole 1111a is drilled so that a predetermined supply can be performed even in a closed state of the door 1111. [ A stronger firepower can be obtained by providing the ashtray 1300 having a plurality of through holes 1310 on the inner bottom surface of the main body 1100 in order to separate the burned ash and the charcoal from the combustible being burned. If necessary, the to-be-combusted material can be placed in the ash receiver 1300.

An extra space of the main body 1100 excluding the auxiliary combustion tube 1400 to be described later can be utilized as an oven space for barbecue, baking, and confectionery as well as air preheating and proper device attachment. For example, a plurality of barbikey rings 1710 are coupled to one side of the upper surface 1120 of the main body to hook the barbeque object, so that the smoke can be indirectly roasted by the radiant heat of the auxiliary combustion tube. So that it is not harmful to hygiene because it does not come into direct contact with the barbecue object, and when it is formed into a square pipe shape, the corner space Can be utilized as a barbecue space. On the other hand, the oven pedestal 1720 can be attached to the left and right sides of the door 1111 at the lower inner side of the main body, or can be used as an oven space for potato balls, baking and confectionery by mounting on the ashtring 1300. In the case where the ashtray 1300 is directly attached to the auxiliary combustion tube 1400 to be described later, although not shown, the shape of the main body 1100 is the same as the shape of the main body 1100 around the lower end of the auxiliary combustion tube 1400, A flat plate having a diameter enough to accommodate the lower end of the auxiliary combustion tube 1400 is mounted on the side of the main body at an angle of 90 degrees with respect to the main body to mount the oven space and the drip pan At this time, the drip pan concave the middle part, and the oil that falls off is guided to the auxiliary combustion pipe so that the combustion of the oil can be directly discharged to the outside. In addition, when the main body door 1111 is opened and used in a rocket stove system, a plurality of air supply holes can be added to the drip pan (oil pan) for additional air supply, and the thermal power can be adjusted by opening / closing the air supply holes. This drip pan (not shown) may further increase the supply of air to the supply hole 1430 of the auxiliary combustion tube instead of suppressing the supply of the gas to the lower end of the auxiliary combustion tube 1400, thereby taking advantage of the wood gas stove, So that it is possible to mount the auxiliary combustion tube flange 1440 on top of the auxiliary combustion tube 1440. Thus, the gap between the auxiliary combustion tube and the first opening 1121 is useful for helping to fume the barbecue object.

On the other hand, when a barbecue is performed using a main body and an auxiliary combustion tube, it is difficult to take advantage of the barbecue flavor, which requires relatively low temperature and steady thermal power due to strong firepower and nondurability. Therefore, It is good to use the charcoal state. In addition, the temperature of the oven can be adjusted by opening and closing the inlet of the auxiliary combustion tube by the cap 1500 of the second opening, and by adding a part of the inlet of the auxiliary combustion tube and injecting the smoke stream,

Inside the main body 1100, an auxiliary combustion tube 1400 is disposed as a combustion chamber in which a substance to be burned is burnt. The auxiliary combustion tube 1400 has an upper portion and a lower portion opened in a pipe shape and a flange 1440 is formed outside the upper portion and an outer diameter of the auxiliary combustion tube 1400 can be inserted into the first opening 1121 of the body 1100 And the flange 1440 extending outward from the upper end of the auxiliary combustion tube 1400 is formed to have a larger outer diameter than the diameter of the first opening 1121 so that the auxiliary combustion tube 1400 is formed by the flange 1440, And the upper surface 1120 of the main body 1100 can be engaged with each other. A plurality of air supply holes 1430 are formed through the side surface of the auxiliary combustion tube 1400 so that air preheated by the body 1100 is supplied to the auxiliary combustion tube. A position corresponding to the body inlet 1110 of the lower side of the auxiliary combustion tube 1400 passes through the inlet 1410 so that the substance to be burned is placed in the auxiliary combustion tube 1400 or introduced into the lower end of the auxiliary combustion tube 1400, 1300). The inlet 1410 is opened and closed by the door 1420, and it is possible to reduce the thermal deviation of the oven space during barbecue, confectionery, and baking at the time of closing. Meanwhile, although not shown, when the inlet door 1420 is detachably attached, it is convenient to place the object to be combusted between the inlet 1410 and the body inlet 1110, which is convenient.

The heat generating unit 1200 disposed on the upper surface of the main body 1100 is formed in a pipe shape having an open bottom and a closed top. The lower opening of the heat generating portion 1200 is coupled to the upper surface of the main body 1100. The second opening 1231 is formed in the upper surface 1230 of the heat generating portion 1200 and the second opening 1231 is opened and closed by the stopper 1500. It can be used as an oven when opened, . A plurality of exhaust holes 1210 are formed in the side surface of the heat generating portion 1200 so that the exhausted heat is exhausted to the outside while the exhaust hole 1210 is formed to have a larger diameter toward the lower side of the heat generating portion 1200, And the exhaust hole having the smallest diameter of the bottom is used as the second supply hole 1610 of the heat concentrating pipe 1600 to be described later The air for secondary combustion is also supplied partly. At this time, the total area of the exhaust holes should be equal to or slightly larger than the cross-sectional area of the auxiliary combustion tube 1400. This is because, in the normal case, the diameter of the communication pipe may be smaller than the cross-sectional area of the auxiliary combustion pipe 1400, but there is no communication, so that if the wind is blown, the exhaust gas is discharged only in one direction. On the other hand, by piercing a plurality of feed holes (not shown) along the second opening of the heat generating portion, it is possible to prepare for the supply amount which may be insufficient depending on the combustion state.

A pipe-shaped heat concentrator 1600 is disposed on the upper surface 1200 of the main body, to which the flange 1440 of the auxiliary combustion tube 1400 is coupled. The heat concentrator 1600 has a plurality of secondary air supply holes 1610 formed on its side to provide a secondary air supply for secondary combustion of unburned gas in the secondary combustion tube 1400 to provide an additional combustion space And sucks the burned heat and the flame in the auxiliary combustion tube 1400 and hands it to the heat generating portion. The heat concentration tube 1600 should be accommodated in the heat generating part 1200 and be formed smaller than the diameter and height of the heat generating part 1200 for securing a heat generating space. The diameter of the first opening 1121 is set to about 1/2 of the height of the heat generating portion 1200 in order to prevent the heat from the auxiliary combustion tube 1400 and the suction of the flame and to secure an additional combustion space and a heat generating space, If the diameter is smaller than the first opening 1121, it is possible to mount a flange (not shown) having a larger diameter than the first opening on the upper surface 1120. In this case, The air supplied to the air supply hole 1430 at the uppermost stage of the air purifier 1400 can not be applied to the combustion of the air and the combustion space of the unburned gas to be forcedly discharged by the air concentration tube 1600 is secured, have. Similarly, when the main body 1100 and the subsidiary combustion tube 1400 are used as the furnace without the heat concentration tube 1600, the inner diameter of the auxiliary combustion tube flange 1440 is smaller than the diameter of the subsidiary combustion tube 1400 and the outer diameter thereof is larger. It is possible to improve the efficiency of combustion by providing a combustion space for the unburned gas. However, as the inner diameter of the flange becomes smaller, the thermal power decreases due to the flue gas resistance.

At this time, the main body 1100 may be provided with a receptacle 1300 having a larger area than the area of the auxiliary combustion tube 1400 so as to be spaced apart from the bottom surface of the main body 1100 by a predetermined interval. The material to be burned can be mounted on the ash receiver 1300. On the other hand, the ashtring 1300 may be welded to the lower end of the auxiliary combustion tube 1400 and attached thereto. In this case, the area of the lower end of the auxiliary combustion tube is reduced and the ashtray pedestal for securing the storage space of the ash and the char is unnecessary, thereby reducing the weight and manufacturing cost, and preventing the auxiliary combustion tube 1400 from being deformed by heat. The combustible material such as harmonious wood may be injected into the auxiliary combustion tube 1400 through the main injection port 1110 and the auxiliary combustion port input port 1410 or the first and second openings. As shown in FIG. 8, the firewood is buried in the auxiliary combustion tube 1400 or horizontally extended to the body inlet 1110 and the auxiliary combustion tube inlet 1410, and the heat and flame are burned in the auxiliary combustion tube 1400, The exhaust gas is exhausted through the central pipe 1600 to generate heat in the heat generating unit 1200 and increase the diameter of the exhaust hole as it goes down along the side surface of the heat generating unit 1600, And can be discharged to the outside. The smoke may be generated somewhat in the beginning, but no smoke is generated after the heat generating part 1600 is heated, and it can be used indoors when the communication hole (not shown) is provided without the exhaust hole. The main body 1100 may be ignited by TLUD (Top Light Up Draft), which is provided with ignition, harmony and air conditioning through a charging port 1110, and a flash bulb is placed on the upper side of the auxiliary combustion tube. The inlet 1110 is opened / closed by a hinge-coupled door 1111, and a separate auxiliary air supply hole may be formed in the door 1111. Therefore, a certain amount of air can be supplied even after the door 1111 is closed. The injection port 1410 may be formed in the lower side of the auxiliary combustion tube 1400 at a position corresponding to the main injection port 1110 so that the harmful lamp may be set up in the auxiliary combustion pipe 1400 through the input port 1410, The combustion efficiency can be increased. The space between the main body 1100 and the auxiliary combustion tube 1400 becomes an air tank for warming up the cold outside air. In addition, a plurality of air supply holes 1430 are formed in the side surface of the auxiliary combustion tube 1400 at predetermined intervals to supply preheated air through the air supply holes 1430, thereby further improving the combustion efficiency.

Therefore, the stove according to the fourth embodiment is a stove / burner that combines the merits of a wood gas stove and a rocket stove. Wood gas stoves are very efficient, but since they are in a batch type, the addition of harmonious woods is unlikely to be added, and the thermal power tends to decrease due to the increase of char when burning for a long time. However, the stove according to the embodiment of the present invention, The charcoal is separated and thus the contact area with the air is enlarged. Therefore, even if the harmful wood is added, the firepower can be controlled by controlling the air supply by the main body door 1111 together with the normal combustion, It is possible to overcome the disadvantages of the rocket stove having the problem that only the firewood needs to be put in comparison with the rocket stove, and also to reduce the production cost due to the simpler structure by eliminating the horizontal introduction part.

The diameter of the main body 1100, the heat generating portion 1200, the heat concentrating tube 1600, the auxiliary combustion tube 1400, and the lid 1500 may be changed in order, and the height may be shorter than that of the main body. It is suitable for moving and camping because it can be made light with smaller volume and thinner material.
