<제 1 연소모드의 동작><Operation in the First Combustion Mode>

Hereinafter, the above-described configuration will be described with reference to the accompanying drawings for the operation during the first combustion mode (ignition) of the stove having the same smart air system.

First, as shown in FIGS. 7 and 10, the first adjustment unit 160 is pushed to the side to open the first opening / closing device 600 to the maximum. Then, one end of the first link 610 is rotated around the fixing unit 620 while the second link 630 is slid to move in the direction of the arrow of FIG. As a result, the cross section of the side passage 210 is completely opened.

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

At this time, if necessary, the second adjustment unit 150 is moved to close the second ventilator 700. As a result, the front passage 553 is opened, and the rear passage 554 is closed. When the ignition is made in this state, air is introduced through the front suction port 190 by natural convection. As shown in FIG. 2, some of the low-temperature air introduced through the front inlet 190 rises through the side passage 210 through the side inlet 200 on both sides, and then through the air curtain outlet 220. Discharged to 115). Air impinging on the see-through window 115 is used for combustion while circulating in the combustion chamber 320. Through this process, the air curtain is continuously operated. Such an air curtain may be operated at all times, or optionally, the stove 100 for the first and second combustion modes.

As shown in FIG. 7, the remaining air of low temperature passing through the front suction port 190 flows into the front passage 553 through the first vent device 600. This is because the rear passage 554 is closed by the second ventilator 700. Thereafter, the air moving to the left and right with respect to the front side moves along both gaps between the lower plate 570 and the first intermediate plate 530, and then collects toward the upper portion of the first intermediate plate 530. Then, the ash tray 180 passes through both sides and comes into contact with the flame 60 through the gap of the combustion grill 170.

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

In the combustion chamber 320, the combustion gas is circulated in a constant direction (counterclockwise in FIG. 3A) by the air supplied by the air curtain outlet 220 and the inclined upper refractory brick 310. A portion of the circulating combustion gas is discharged to the discharge pipe 120 through the upper passage 340 from the top. By this process, the first combustion mode is performed.

<제 2 연소모드의 동작><Operation in Second Combustion Mode>

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

First, as shown in FIG. 8, the second adjustment part 150 is partially repositioned to partially close the front passage 553 and the side passage 210. Then, the first ventilator 160 is rotated to open the second ventilator 700. As a result, the front passage 553 is partially closed, and the rear passage 554 is opened. This state is achieved sequentially after the first combustion mode, and air is introduced through the front inlet 190 by natural convection. As shown in FIG. 2, some of the air introduced through the front inlet 190 rises through the side passage 210 through the side inlet 200 on both sides, and then through the air curtain outlet 220, the viewing window 115. To be discharged. Air impinging on the see-through window 115 is used for combustion while circulating in the combustion chamber 320. Through this process, the air curtain is continuously operated. This air curtain is such that the stove 100 is always operated for the first and second combustion mode.

As shown in FIG. 8, the remaining air of low temperature passing through the front suction port 190 flows into the rear passage 554 through the second venting device 700. Thereafter, after rising through the rising passage 556, the rear slit 400 is introduced into the rear passage 330. The air rising by the rear passage 330 is preheated to the primary and collides with 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 used for combustion while circulating.

Since the second combustion mode (normal state) requires a relatively small amount of air compared to the first combustion mode, it is preferable to reduce the dimensions of the rear slit 400 and the rear passage 330.

In the combustion chamber 320, the combustion gas is circulated in a constant direction (counterclockwise in FIG. 3A) by the air supplied by the air curtain outlet 220 and the inclined upper refractory brick 310. A portion of the circulating combustion gas is discharged to the discharge pipe 120 through the upper passage 340 from the top. By this process, the second combustion mode is performed.

In the first combustion mode, a lot of air is introduced, and in the air curtain, preheated air is discharged from the sidewalls, so that a condition close to complete combustion may be formed in the combustion chamber. In addition, since the air preheated by the air curtain is supplied 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.

<변형예><Variation example>

In the hearth of the present invention, the air curtain discharged from the upper portion of the viewing window 115 is shown and described, but the position may be changed to be discharged from the side or the lower surface of the viewing window 115, and the air curtain is discharged from two or more of the upper, lower, left and right sides. You can change the flow path as much as possible.

Although the present invention shows and describes a natural supply method of air by natural convection, it is also possible to control the amount of air by installing a blower fan in some zones and controlling it according to design needs.

Although the first combustion mode and the second combustion mode are illustrated and described separately for explanation and understanding, they may be mixed according to the needs of the user.

A stove equipped with the smart air system described above may not be limited to the configuration and method of the embodiments described above, but the embodiments may be selectively or partially all of the embodiments so that various modifications may be made. It may be configured in combination.

The present invention relates to a stove having a smart air system and has industrial applicability.
