BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a stove having a smart air system, and more particularly, to a stove having a smart air system that is provided with a natural circulation air curtain to prevent soot from being smudged and to achieve complete combustion.

There are fireplaces that use solid fuels such as pellets, briquettes, and firewood as home heating, industrial, or camping fireplaces. Most of such conventional fireplaces have a vertical communication type structure. That is, the burned gas is injected into the lower part of the cylindrical shape, and the combustion gas is discharged from the upper part. To this end, the front door is equipped with a viewing window to view the internal combustion chamber.

However, as combustion of the solid fuel proceeds in the combustion chamber, soot or smoke is generated, and some of them are deposited in the sight window to obscure the field of view. In order to solve this problem, it was inconvenient to clean the inside of the window frequently.

Also, the amount of air required for the stove during ignition and normal combustion is different. That is, a large amount of air is required at the time of ignition, and a smaller amount of air is required at the time of steady-state combustion. Therefore, conventionally, the user adjusts the amount of air by empirically adjusting the opening / closing sectional area of the air inlet.

When such control is immature, a sufficient amount of air is not supplied at the time of ignition, so that a lot of soot is easily generated and incomplete combustion is achieved. Also, during steady-state combustion, combustion did not last for a desired period of time.

The upper door 130, the door 110, and the lower cover 140 are provided on the front surface, and the discharge pipe 120 is provided on the upper surface. Lt; / RTI &gt;

The upper door 130 is for opening / closing the upper storage part 135, and it is possible to put food such as the sweet potato 137 into the cooking cavity as shown in FIG. 3A. The door 110 is openable and closable through a hinge, and a viewing window 115 is formed. A combustion grill 170 is provided to open the door 110 and open the combustion chamber 320 to raise the firewood 50. The ash receiver 180 is formed below the combustion grill 170.

A front suction port 190 is formed in the lower cover 140 so that air is naturally sucked in. The first and second control units 160 and 150 are extended from the front suction port 190.

The side air inlet 200 is formed in a lower portion of both side walls adjacent to the lower cover 140 and communicates with the side air passage 210 which is perpendicular to the inside of the side wall of the stove 100. These side passages 210 are formed on both side walls, and communicate with the air curtain outlet 220 formed in the horizontal direction at the upper end.

FIG. 3 is an operational side view of the first combustion mode in which the cold air introduced into the lower portion is supplied to the combustion chamber 320 through the front passage 553, FIG. 3B is an operation side view of the second combustion mode in which the cold air introduced into the lower portion is supplied to the combustion chamber 320 through the rear passage 554. FIG. In the present invention, the first combustion mode means a state and position in which a large amount of air must flow in order to ignite the firewood 50, and the second combustion mode means a combustion state in a desired time or a calorific value with respect to the firewood 50 being burned. (Steady state) and position for constant continuation.

The lower passage 350 is formed at a lower portion of the stove 100 and is connected to the front suction inlet 190 of the lower cover 140. A control box 500 is provided on the upper portion of the lower passage 350. The control box 500 is provided with the ash receptacle 180 and the combustion grill 170 is disposed on the upper portion thereof.

The detailed configuration of the control box 500 will be described in Figs. The ash receiver (180) is slidable to the front and houses the ash falling into the gap of the combustion grill (170). The ash receiver 180 is as wide as the combustion grill 170, so that the air supplied from the lower portion moves upward along the side surface of the ash receiver 180.

The firewood 50 is placed on the combustion grill 170 and ignited by a separate ignition device (not shown) or by the user. In addition to the firewood 50 as a solid fuel, any combustible solid matter such as wood pulp, pellets, and briquettes may be used.

The refractory bricks 300 form the bottom surface, side surface, and back surface of the combustion chamber 320. In particular, the back surface passages 330 are spaced apart from each other by a predetermined distance on the back surface. The upper end of the refractory brick 300 is spaced apart from the upper refractory bricks 310 and used as an air flow path in the second combustion mode.

The upper refractory bricks 310 are connected to the back and side surfaces and are fixed in a tilted state. Accordingly, the air supplied through the back passage 330 and the air circulating inside the combustion chamber 320 can be naturally mixed.

The lower end of the discharge pipe 120 is connected to the upper surface passage 340 and the intermediate portion passes through the upper storage part 135 and discharges the combustion gas to the outside.

Fig. 4 is an exploded perspective view of the adjustment box 500 shown in Fig. 3a, and Fig. 5 is a perspective view of the adjustment box 500 shown in Fig. 4 assembled and the second finishing material 582 disassembled. 4 and 5, the adjustment box 500 is a device for determining whether to supply air in the first combustion mode or air in the second combustion mode. The control box 500 includes a top plate 510, a first intermediate plate 530, a second intermediate plate 550, and a bottom plate 570.

The upper plate 510 is a plate-shaped steel material, and a quadrangular vent hole 410 is formed in the middle thereof, and a rear slit 400 is formed through the rear surface thereof.

The first intermediate plate 530 is manufactured by bending a plate-like steel material, and is assembled to the lower portion of the upper plate 510. It is angled U-shaped with respect to the front by bending, and the rear part is symmetrically incised for air passage.

The second intermediate plate 550 is a plate-shaped steel and is assembled to the lower portion of the first intermediate plate 530. The second intermediate plate 550 is machined through two right angle bends.

The lower plate 570 is manufactured by cutting, bending and welding the plate-like steel material. First and second finishing materials 580 and 582 are welded to the front and rear surfaces of the first and second ventilation devices 600 and 700, respectively.

The first and second ventilation devices 600 and 700 are formed by stacking a pair of disks having through holes formed therein. One disk is fixed to the lower plate 570, and the other disk is rotatably mounted on a fixed disk. Therefore, the opening of the through hole is adjusted by the rotating disk and the amount of the introduced air can be controlled thereby.

Each of the components constituting the adjustment box 500 may be merged or omitted depending on design choices.

6 is a bottom perspective view showing a state in which the adjustment box 500 shown in FIG. 4 is assembled. As shown in FIG. 6, first and second adjusting portions 160 and 150 are rotatably installed on the bottom surface of the adjusting box 500. For ease of understanding, the opening / closing apparatus of the side passage as shown in Figs. 9 and 10 is omitted, and a more detailed description will be given in the description of the constitution of Figs. 9 and 10. Fig.

One end of the first adjuster 160 is exposed to the front of the stove 100 so that the user can hold it by hand and the other end is welded to the rotatable disk of the first ventilator 600. Therefore, when the first adjuster 160 is rotated to the left or right, the first ventilator 600 rotates.

The second adjuster 150 is installed in parallel with the first adjuster 160. One end of the second adjuster 150 is exposed to the front of the stove 100 so that the user can hold it by hand and the other end is welded to the rotatable disk of the second ventilator 700. Therefore, when the second adjuster 150 is rotated to the left or right, the second ventilation device 700 rotates.

9 is a bottom view of the adjustment box 500 in a state in which the side passage 210 is closed. 9, one end of the first link 610 is fixed with a bolt or the like so as to be rotatable in a circumferential region of the first ventilator 600, and the other end is connected to the second link 630. [ A long hole is formed in the intermediate region of the first link 610, and a fixing portion 620 fixed to the lower plate 570 is passed through the long hole. One end of the second link 630 is pivotally connected to the first link 610 and the other end is extended enough to cover the end surface of the side passage 210. That is, the other end of the second link 630 can be opened and closed while sliding on the end surface of the side passage 210.

The third link 660 is extended and fixed to the circumference of the first ventilator 600 by welding or the like.

One end of the fourth link 650 is pivotally connected to the third link 660 and the other end is pivotally connected to the fifth link 640.

One end of the fifth link 640 is connected to the fourth link 650, and the other end is a free end that can open and close a cross section of the side passage 210.

<First Combustion mode  Action>

Hereinafter, the operation in the first combustion mode (ignition) of the stove equipped with the same smart air system as described above will be described with reference to the accompanying drawings.

First, as shown in FIGS. 7 and 10, the first control unit 160 is pushed to the side to open the first opening and closing apparatus 600 at the maximum. Then, one end of the first link 610 rotates and rotates about the fixed portion 620, and the second link 630 slides in the direction of the arrow in FIG. Whereby the cross section of the side passage 210 is fully opened.

At the same time, as the fourth link 650 rotates, the fifth link 640 slides in the direction of the arrow in Fig. 10, so that the side passage 210 is fully opened.

At this time, the second control unit 150 is moved as necessary to close the second ventilation device 700. Thereby, the front passage 553 is opened and the rear passage 554 is closed. When ignition is performed in this state, air is introduced through the front suction port 190 by natural convection. Part of the low-temperature air introduced through the front suction port 190 rises through the side passage 210 through the side suction ports 200 on both sides and then passes through the air curtain discharge port 220 115). The air impinging on the sight window 115 is circulated in the combustion chamber 320 and used for combustion. Through this process, the air curtain is continuously operated. Such an air curtain may or may not operate for the first and second combustion modes of the stove 100 at all times.

As shown in FIG. 7, the low-temperature air remaining through the front suction inlet 190 flows into the front passage 553 through the first ventilation device 600. This is because the rear passage 554 is closed by the second ventilation device 700. Then, the air moving to the left and right with respect to the front surface moves along the clearance between the lower plate 570 and the first intermediate plate 530, and then collects on the upper portion of the first intermediate plate 530. Then, the ash receiver 180 is passed through both sides to reach the flame 60 through the clearance of the combustion grill 170.

Since a large amount of air is required for the first combustion mode (ignition), it is preferable to sufficiently increase the dimensions of the front passageway 553 and the like of the first ventilation device 600.

In the combustion chamber 320, the air supplied by the air curtain outlet 220 and the tilted upper refractory bricks 310 cause the combustion gas to circulate in a certain direction (counterclockwise in FIG. 3A). A part of the combustion gas circulated is discharged from the upper portion to the discharge pipe 120 through the upper surface passage 340. The first combustion mode proceeds by this process.

<2nd Combustion mode  Action>

Hereinafter, the operation in the second combustion mode (steady state) of the stove having the air curtain as described above will be described with reference to the accompanying drawings.

First, as shown in FIG. 8, the second regulating portion 150 is partially in place to partially close the front passageway 553 and the side passageway 210. Then, the first adjusting unit 160 is rotated to open the second ventilation unit 700. [ Thereby, the front passage 553 is partially closed and the rear passage 554 is opened. This state is sequentially performed after the first combustion mode, and air is introduced through the front suction port 190 by natural convection. A part of the air introduced through the front suction port 190 rises through the side passages 210 through the lateral suction ports 200 on both sides and then passes through the air curtain outlet port 220 through the front window 115 ). The air impinging on the sight window 115 is circulated in the combustion chamber 320 and used for combustion. Through this process, the air curtain is continuously operated. Such an air curtain causes the stove 100 to always operate for the first and second combustion modes.

As shown in FIG. 8, the low-temperature air remaining through the front suction inlet 190 flows into the rear passage 554 through the second ventilation device 700. Thereafter, the liquid is lifted through the ascending passage 556 and then introduced into the rear passage 330 by the rear slit 400. The air rising by the back passage 330 is firstly preheated and impinges on the lower surface of the upper refractory brick 310 and then flows into the combustion chamber 320. In the combustion chamber 320, the air supplied by the air curtain and the air supplied by the rear passage 330 are circulated and used for combustion.

In the second combustion mode (steady state), a relatively small amount of air is required in comparison with the first combustion mode, so that it is desirable to reduce the dimensions of the back slit 400, the back passage 330, and the like.

In the combustion chamber 320, the air supplied by the air curtain outlet 220 and the tilted upper refractory bricks 310 cause the combustion gas to circulate in a certain direction (counterclockwise in FIG. 3A). A part of the combustion gas circulated is discharged from the upper portion to the discharge pipe 120 through the upper surface passage 340. By this process, the second combustion mode proceeds.

In the first combustion mode, a large amount of air flows in, and in the air curtain, preheated air is discharged from the side wall, so that conditions close to complete combustion can be formed in the combustion chamber. In addition, since the preheated air is supplied by the air curtain even in the second combustion mode, even if a small amount of air is supplied through the rear passage 330, an environment close to complete combustion is formed.

< Variation example >

Although the air conditioner according to the present invention has been described and illustrated in the upper part of the viewing window 115, it can be changed in position to be discharged from the side or bottom surface of the viewing window 115. In addition, So that the flow path can be changed.

Although the present invention has shown and described the natural supply method of air by natural convection, it is also possible to install a blowing fan in a certain area according to design needs and control the amount of air by controlling the blowing fan.

Although the first combustion mode and the second combustion mode have been separately shown and described for the sake of explanation and understanding, they may be mixed according to the needs of the user.

The above described stove having the smart air system can be applied to only the configuration and the method of the embodiments described above, but the embodiments can be modified so that all or some of the embodiments are selectively And may be configured in combination.
