Figure 1 is a perspective view of a dual combustion device according to an embodiment of the present invention.

Referring to FIG. 1 , the dual combustion furnace 10 may include a body portion 100, a combustion portion 200, a support portion 300, and a cover portion 400.

The body portion 100 has a hollow shape with open upper and lower portions, and a first inlet hole 101 through which external air primarily flows may be formed around the lower portion. For example, the body portion 100 may have a hollow shape with open upper and lower portions, and a plurality of first inlet holes through which external air primarily flows may be formed in the lower portion. Through this, outside air can be introduced more easily.

The combustion unit 200 is accommodated inside the body unit 100, and a second inlet hole 201 through which air is secondary may be formed around the upper portion. For example, the combustion unit 200 may be accommodated inside the body unit 100, and a plurality of second inlet holes 201 through which air may secondaryly flow may be formed around the upper portion. Through this, the external air flowing into the first inlet hole 101 moves to the second inlet hole 201, allowing air to flow into the combustion unit 200 through a dual path. Ultimately, the fuel can be burned more effectively due to the dual intake of air.

In addition, the air introduced into the combustion section through the second inlet hole 201 may have the effect of maintaining the flame generated by combustion by supplying additional air upward from the time the fuel is ignited.

The support part 300 may be seated on the ground and support the body part 100 and the combustion part 200. For example, the support unit 300 may be seated on the ground or deck of a camping area to support the body unit 100 and the combustion unit 200. Through this, since the combustion part 200, where combustion occurs, is located a certain distance away from the ground due to the support part 300, accidents where fire spreads to grass or grass on the ground can be prevented, and the wood tech is not scorched. You can.

The cover portion 400 may be formed along the upper circumference of the combustion section 200 and cover a portion of the upper surface. For example, the cover portion 400 may be curved outward along the upper circumference of the combustion section 200 to cover a portion of the upper surface. Through this, the cover part 400 can control the emission of smoke when smoke rises from the combustion part 200, and is formed in a canopy shape curved toward the outside to send smoke to the center and discharge it. It is possible to prevent a situation where a fire goes out due to raindrops.

Figure 2 is an exploded perspective view of a dual combustion furnace according to an embodiment of the present invention, and Figure 3 is a perspective cross-sectional view of a dual combustion furnace according to an embodiment of the present invention.

Referring to FIGS. 2 and 3 , the combustion unit 200 may include a support plate 210, a support frame 220, an inlet plate 230, a grill plate 240, and a combustion frame 250. Through this, by having a simple structure, it is light in weight, easy to move, and suitable for outdoor activities.

The support plate 210 is connected to the upper side of the support part 300 and has a step in a shape corresponding to the support part 300, and can seat the body part 100 and the combustion part 200. For example, the support plate 210 is connected to one side of the support part 300 placed on the ground, and a step is formed in a circular shape corresponding to the support part 300 to seat the body part 100 and the combustion part 200. You can. Through this, the step support portion 300 and the support plate 210 are fixed more firmly so that the body portion 100 and the combustion portion 200 do not tip over or fall over due to impact.

The support frame 220 is arranged at a certain distance from the support plate 210, and has a semicircular groove on the surface facing the support part, an inner groove formed with a semicircular protrusion on the surface facing the cover part, and an inner groove formed from the inner groove. It may include an outer groove that is spaced apart and formed in a shape corresponding to the inner groove.

In addition, the support frame 220 is disposed at a certain distance from the support plate 210, and two inner and outer grooves 220b and 220c with a semicircular cross-section may be formed around the outer shell. For example, the support frame 220 is arranged approximately 5 cm apart from the support plate 210, and two inner grooves 220b and outer grooves 220c, each of which has a semicircular cross-section, are formed around the outer shell, and the grooves get smaller toward the center. The grooves 220b and 220c may be formed into a frame curved in a protruding direction. Through this, the inlet plate 230, grill plate 240, and combustion frame 250 can be seated and fixed on the support frame 220. In particular, referring to the enlarged view of FIG. 1, the inlet plate 230 is fixed to the inner groove 220b of the support frame 220, and the grill plate 240 is fixed to the outer groove 220c of the support frame 220. By being hung and fixed, the inlet plate 230 and the grill plate 240 can always be kept a certain distance apart without contacting each other. Ultimately, the external air introduced through the first inlet hole 101 can move more smoothly to the grill hole 241 through the central passage 220a and between the protrusions 230a.

The support frame 220 is formed to be curved in the direction in which the grooves 220b and 220c are dug toward the center, and may be formed with an open center. For example, the support frame 220 may be formed to be curved in the direction in which the fuel is placed as it moves toward the center. Through this, the external air introduced through the first inlet hole 101 can move more smoothly along the slope, and the closer it gets to the center, the smaller the inlet becomes, so the flow rate of air increases, making combustion more effective. . In addition, the support frame 220 allows external air introduced from the first inlet hole 101 to pass more quickly and easily through the central passage 220a.

The inflow plate 230 is coupled to the inner groove 220b of the support frame 220, and is formed to be concave toward the center to correspond to the support frame 220, and a plurality of protrusions 230a may be formed around the outer edge. there is. For example, the inlet plate 230 is fixed to the inner groove 220b of the support frame 220, and has a shape corresponding to the support frame 220, and may be curved toward the center and protrude concavely. . Through this, the air introduced through the central passage 220a may be able to move more smoothly according to the curve of the inflow plate 230.

As another example, a plurality of protrusions 230a are formed around the outer edge of the inlet plate 230 at a predetermined distance apart from each other, and the protrusions 230a can be fixed to the inner groove 220b of the support frame 220. Through this, the air introduced through the central passage 220a can pass between the protrusions 230a formed at a certain distance apart, so that the air can move more easily.

The grill plate 240 is coupled to the outer groove 220c of the support frame 220, is formed concavely in correspondence with the inlet plate 230, and can accommodate fuel. For example, the grill plate 240 may be fixed to the outer groove 220c of the support frame 220 and may be formed to be spaced a certain distance away from the inlet plate 230. Through this, the air flow becomes smoother, allowing fuel to be burned more effectively.

The combustion frame 250 is connected to the grill plate 240, is spaced apart from the body portion 100, and may be formed in a hollow shape with the upper and lower portions open. For example, the combustion frame 250 may be connected to and surround the grill plate 240 and may be spaced apart from the body portion 100 . Through this, combustion occurs in a closed space, and even the smoke generated due to incomplete combustion is recombusted, which can lead to complete combustion, no smoke harmful to the human body is generated, and the fire power can be very strong.

The grill plate 240 may further include a grill hole 241 through which air introduced through the first inlet hole 101 can move into the combustion unit 200. For example, the grill plate 240 may further include a plurality of grill holes 241 through which air introduced through the first inlet hole 101 can move into the combustion unit 200. Through this, the fuel can be burned more effectively by allowing air to pass over a large area of the fuel, and the thermal power can be significantly increased, resulting in high energy efficiency even with less fuel consumption.

The support portion 300 may have rounded corners that contact the ground and corners that contact the support plate 210. Through this, since the edges are not sharp, when moving or transporting the furnace 10, hands may not be cut or wood tech may not be scratched, and the support plate 210 may not be worn.

Figure 4 is a front cross-sectional view showing the air movement path of a dual combustion furnace according to an embodiment of the present invention.

A first path (R1) through which air flows into the first inlet hole (101) and moves through the central passage (220a) to the grill hole (241) and into the combustion unit (200), and the air flows into the first inlet hole (101). ) may have a second path (R2) through which it flows into the second inlet hole 201 and moves into the combustion unit 200. For example, the first path R1 is a path in which external air flows into the first inlet hole 101, passes through the central passage 220a, passes between the protrusions 230a, moves to the grill hole, and reaches the fuel. It may be, and in the second path (R2), after external air flows into the first inlet hole 101, it passes through the empty space between the body portion 100 and the combustion frame 250 and reaches the second inlet hole 201. This may be a route to reach fuel. Through this, by having a double air movement path, the flow of air supplied from the outside is smooth, which has the effect of completely burning firewood and pellets used as fuel.

In addition, since the air in the second path (R2) flowing into the second inlet hole 201 moves in the horizontal direction, unlike the air in the first path that moves in the vertical direction, it improves the air turbulence effect and improves combustion efficiency. and a flame can be formed by combustion of the air stored in the cover part 400 and the incomplete combustion part of the fuel, and the air flowing in from the second inlet hole 201 also forms a flame, which is called 'bulmeong' in slang. You can enjoy this activity more, and there are a variety of things to see as fireworks are produced.

In addition, the dual combustion furnace 10 can significantly increase combustion efficiency due to the air introduced through the double structure of the air inlet hole.

Figure 5 is a perspective cross-sectional view showing a dual combustion furnace according to an embodiment of the present invention.

The double combustion furnace 10 is formed to surround a portion of the outer surface of the body portion 100, and includes a first control portion 101a and a combustion portion 200 that are vertically movable and can control the air flowing into the first inlet hole 101. ) It may further include a second control unit (201a) formed inside, capable of controlling the air flowing into the second inlet hole (201). For example, the first adjustment portion 101a may be formed to surround a portion of the outer surface of the body portion 100 and may be vertically moved. Through this, the inflow of air into the first inlet hole 101 can be controlled. In particular, referring to the enlarged view of FIG. 4, the first control unit 101a can completely block the cross section of the first inlet hole 101 to block the inflow of air, thereby incinerating the fuel whose air has been blocked. can be stopped more quickly. Additionally, if the heat or flame of the fuel is too strong, the heat and flame can be reduced by blocking a portion of the cross section and controlling the inflow of air.

As another example, the second control unit 201a may control the inflow of air into the second inlet hole 201 by blocking or not blocking the cross section of the second inlet hole 201. Through this, the size of the flame can be reduced by blocking the second inlet hole 201, which creates a flame by the inflow of air, and when it is desired to use only the air moving in the first path R1, the second control unit 201a ) can be moved vertically to block the cross section of the second inlet hole 201 to prevent the inflow of air. Ultimately, the user can control the thermal power of the fuel and, due to the above structure, can perform more diverse roles (stove, food cooking, fire pit, campfire, etc.).

The cover portion 400 may be formed to protrude outward and be curved toward the center. Through this, the influence of wind can be reduced and the use of fuel can be continued for a long time, and food ingredients or necessary items can be placed on the cover part 400.

The support part 300 is a cylinder with an empty interior, and a ventilation hole 310 may be formed on the side. For example, the support part 300 may be a cylinder with an empty interior, and a plurality of ventilation holes 310 in a sawtooth shape may be formed on the side. Through this, the heat generated inside the support part 300 during combustion can be circulated, and there can be a cooling effect through wind.

The body serration 100a may be formed on the outer surface of the body portion 100 as a triangular groove. Through this, the coupling between the body portion 100 and the first adjusting portion 101a can be made more robust. In addition, the air flowing into the first inlet hole 101 can be more easily controlled.

The first adjustment portion 100b has a shape corresponding to the body portion 100a and may be formed on a surface where the first adjustment portion 101a and the body portion 100 contact each other. Through this, the user can adjust the first adjustment unit 101a more easily. In addition, the protrusions and grooves formed in the first adjustment busseration 100b and the body buseration 100a are fitted into each other, thereby preventing the risk of the coupling being separated or loosened when using the furnace.

The combustion subsertion 200a may be formed as a triangular groove on the inner surface of the combustion unit 200. Through this, the coupling between the combustion unit 200 and the second control unit 201a can be made more solid. In addition, the shape of the flame formed by air flowing in from the second control hole 201c can be more easily adjusted.

The second control undersertion 200b has a shape corresponding to the combustion undersertion 200a and may be formed on a surface where the second control part 201a and the combustion part 200 come into contact. Through this, the user can more easily adjust the second adjustment unit 201a. In addition, the protrusions and grooves formed in the second adjustment busseration 200b and the body buseration 200a are fitted and coupled to each other, thereby preventing the risk of the coupling being separated or loosened when using the furnace.

Figure 6 is a cross-sectional view showing the operation of the second control unit according to an embodiment of the present invention.

The second inlet hole 201 has a cross-sectional area that allows a smaller amount of air to pass than the first control hole 201b, where one side of the cross section is formed at an angle and the other side is formed in the shape of a semicircle. It may further include a second adjustment hole (201c). For example, the second inlet hole 201 further includes a water drop-shaped first control hole 201b and a circular second control hole 201c that allows a smaller amount of air to pass through than the first control hole 201b. can do. Through this, both the first adjustment hole (201b) and the second adjustment hole (201c) are blocked using the second adjustment part (201a) capable of vertical movement, or only the first adjustment hole (201b) is blocked, or the second adjustment hole (201b) is blocked. Only the hole 201c can be blocked, or both the first adjustment hole 201b and the second adjustment hole 201c can be opened. When only the first control hole 201b is blocked, a flame with a circular cross-section may be formed because air flows only from the second control hole 201c. If only the second control hole 201c is blocked, a flame with a cross section of a water drop may be formed because air flows only from the first control hole 201b. When both the first control hole 201b and the second control hole 201c are blocked, non-control may be possible because only the air flowing into the first path R1 participates in the combustion process. When both the first control hole (201b) and the second control hole (201c) are opened, the largest amount of air, including the air flowing into the first path (R1), flows into the combustion section 200 in a short time. Incineration is possible. Ultimately, by easily adjusting the height of the second adjuster 201a, the furnace can be used for a long time and the fire can be adjusted to suit the user's preference.

In addition, the shape of the flame formed can be adjusted by blocking only a portion of the first control hole 201b.

As another example, all air flowing into the combustion unit 200 can be blocked by using the first control unit 101a and the second control unit 201a together. Through this, even if fuel remains, it can be extinguished more quickly. Ultimately, by immediately blocking the inflow of air, rapid fire extinguishment becomes possible and, through this, the emission of pollutants can be minimized.

Figure 7 is a perspective view showing a double combustion furnace using a support according to an embodiment of the present invention.

For example, the support portion 300 may be formed of a wooden board in which a square support groove 320 is formed on one side and a coupling groove 330 and a fitting groove 340 are formed in the center to be coupled to each other. For example, the support part 300 is made of two wooden boards, and a square support groove 320 is formed on one side of each side, and a square coupling groove 330 and a fitting groove 340 are formed in the center so that they can be coupled to each other. there is. Through this, the body portion 100 and the combustion portion 200 can be supported more firmly and robustly, and the risk of burns and fires can be prevented since it is a wood material with low thermal conductivity.

The first support portion 300a may have a square support groove 320 formed on the outer side and a coupling groove 330 formed at the center. For example, the first support portion 300a may be made of rectangular wood, with two square support grooves 320 formed on one side, and a square coupling groove 330 formed at the center of the side opposite to the support groove 320.

The second support portion 300b may have a square support groove 320 formed on its outer surface, and a fitting groove 340 corresponding to the coupling groove 330 may be formed.
