Utility Model Registration No. 3142375

  However, in the above-mentioned conventional wood stove, when wood firewood is intended to burn a relatively long wood fire such as, for example, logs, wood vertically divided from this, waste wood from buildings, etc. Even if this soot W is introduced from the port 103 and enters the combustion chamber 101, the support of the soot W is unstable in the combustion chamber 101 and the posture thereof becomes irregular, so that the soot W is uniformly stabilized. There was a problem that it was difficult to burn.

  The present invention has been made in view of the above problems, and even a relatively long soot can be supported so that the attitude of the soot is regular in the combustion chamber, so that the soot can be made uniform. An object of the present invention is to provide a wood stove that can be stably burned.

  In order to achieve such an object, the soot stove of the present invention is a soot stove in which soot is introduced from above and burned, and a box-shaped main body having a combustion chamber in which soot burns, and an axis line on the upper part of the main body A soot supply which is configured as an input port into which a soot that can be opened and closed with an upper opening is opened, and whose lower opening communicates with the combustion chamber and supplies the introduced soot to the combustion chamber A body, an opening provided at a front portion of the main body and capable of opening and closing, an air supply opening portion provided at the main body and capable of adjusting an opening for supplying air to the combustion chamber, and a chimney provided at a rear side of the main body. And an exhaust port for exhausting exhaust gas from the combustion chamber. The combustion chamber may be provided with a grate, and may not be particularly provided.

  Thus, for example, when trying to burn a relatively long firewood, such as a log, a vertically divided tree or a waste wood of a building, this firewood is placed with its one end down from the supply port of the firewood supply body. throw into. In addition, when the length of the kite is a length that protrudes from the charging port of the kite supply body, it is appropriately cut and used. In this case, since the soot supply body is formed in a cylindrical shape and is inclined, one end of the soot is aligned and supported by the bottom wall of the main body so as to face the combustion chamber. In the combustion chamber, it burns from one end of the aligned soot. Combustion is performed by appropriately adjusting the amount of air by changing the opening of the air supply port. As the soot burns, soot gradually slides down along the axis of the soot supply. During this combustion, the soot supply body inlet is closed, so that the inside of the upper side of the soot supply body is substantially oxygen-free, so that only one end of the soot located on the bottom wall side of the combustion chamber burns. Be made. For this reason, the soot does not burn at once, but gradually burns from the bottom, so that the combustion time becomes longer, and a long time combustion can be obtained with one injection of soot, and fuel supply management is easy Become. Further, during this combustion, since the soot is supported on the wall surface of the soot supply body along the axis of the soot supply body along the longitudinal direction thereof, even if the soot is relatively long, The posture becomes regular and soot is burned uniformly and stably. The combustion gas generated in the combustion chamber is exhausted from the chimney. Further, the ash after combustion may be taken out as appropriate by being provided at the front part of the main body and opening the opening. Of course, even a soot with a relatively short length falls into the combustion chamber if it is introduced from the inlet, so that it can of course be burned.

And if necessary, the axial length from the center of the inlet of the soot supply body to the combustion chamber of the main body is set to 700 mm to 2000 mm. It will be possible to reliably handle relatively long habits.
In addition, the inclination angle θ of the soot supply body with respect to the horizontal plane is set to θ = 70 ° ± 5 ° as necessary. Since the angle is relatively close to a right angle, the soot becomes almost upright, so that air can easily enter between the soots, and the soot can be burned more uniformly and stably.
Further, if necessary, the soot supply body is inclined so that the inlet of the soot supply body is located on the front side of the main body. Since the input port is located on the front side of the main body, the input is easier than in the case of being on the side.

  Further, if necessary, a pair of the air supply port portions are provided on both sides of the front portion of the main body so as to be mirror-symmetric with respect to the axis of the rod supply body. As a result, air can be supplied from both sides to one end of the bottle that is supported and aligned by the bottom wall of the main body, so that the air flow is improved, and the bottle is more evenly stabilized. Can be burned.

In this case, it is effective to provide a plurality of pairs of the air supply port portions. Since air can be supplied from a large number of air supply ports, air circulation is improved accordingly, and soot can be burned more uniformly and stably.
In this case, any one of the plurality of sets of the air supply ports is provided such that the outlet thereof is positioned on the front side and the lower side of the combustion chamber, It is effective to provide one set of air supply ports so that the outlets are located on the front side and the upper side of the combustion chamber. Since air blows from one side to the other on one end of the soot that is supported and aligned by the bottom wall of the main body, the air circulation is improved in this point as well, and soot is burned more uniformly and stably. be able to.

  According to the present invention, for example, when a relatively long firewood such as a log, a vertically divided wood or a waste wood from a building is to be burned, the firewood is lowered from one end of the firewood supply port. The soot supply body is formed in a cylindrical shape and is inclined, so that the soot is supported on the wall surface of the soot supply body along the axis of the soot supply body along its longitudinal direction. One end portion of the soot is aligned and supported by the bottom wall of the main body so as to face the combustion chamber, and burns from one end portion of the aligned soot. Therefore, even if the soot is relatively long, the attitude becomes regular in the combustion chamber, so that the soot can be burned uniformly and stably.

It is a perspective view which shows the wood stove concerning embodiment of this invention. It is a figure which shows the wood stove concerning embodiment of this invention, (a) is a top view, (b) is a side view, (c) is a front view.

Hereinafter, a wood stove according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 1 to FIG. 4, the soot stove S according to the embodiment of the present invention is one in which soot W is introduced from above and burned, and has a box shape having a combustion chamber 2 in which soot W burns. A main body 1 is provided. The main body 1 is formed in a hollow rectangular parallelepiped shape with a metal such as iron. A support column 3 having a lower end projecting from the bottom surface of the main body 1 is welded and fixed at four positions on the left and right sides of the main body 1, and a leg portion 4 is formed by the lower end portion of the support column 3. The body 1 is supported on the ground by the portion 4. Further, plate-like fins 5 for heat dissipation are projected from the bottom surface outside, rear surface outside, and both side surfaces outside of the main body 1.

  Further, in the approximate center of the upper portion of the main body 1, as with the main body 1, a rod supply body 10 formed in a cylindrical shape with a metal such as iron is projected by welding. The rod supply body 10 is configured to project from the rod supply body 10 with its axis P inclined, and the upper opening 11 is configured as an input port 12 into which an openable / closable rod W is inserted. The soot W introduced in communication with the combustion chamber 2 is supplied to the combustion chamber 2. A lid 15 that can be opened and closed via a hinge 14 that opens and closes the charging port 12 is provided at the charging port 12 of the basket supply body 10. A handle 16 is provided on the lid 15 and is gripped when opening and closing.

The soot supply body 10 is inclined so that the inlet 12 is positioned on the front side of the main body 1. For example, the inclination angle θ (FIG. 2B) of the soot supply body 10 with respect to the horizontal plane is θ = 70 ° ± 5 °. The length L of the axis P from the center of the charging port 12 of the soot supply body 10 to the combustion chamber 2 of the main body 1 is set in the range of 700 mm to 2000 mm. In this range, it is possible to reliably cope with relatively long ridges W. The vertical dimension of the main body is desirably in the range of 300 mm to 500 mm. Thereby, it can respond to the eaves of the length of 1000 mm-2500 mm.
In the embodiment, for example, as shown in FIG. 2, the main body 1 is 500 mm wide, 400 mm long, and 914 mm long, and the cocoon feeder 10 has a diameter of 485 mm, an inclination angle θ = 70 °, The length L of the axis P is set to 900 mm.

  An opening 20 that can be opened and closed is formed in the front portion of the main body 1. The opening 20 is provided with a door 22 that can be opened and closed via a hinge 21. The door 22 is provided with a window 23 made of transparent glass or the like. Further, an exhaust port 25 for exhausting exhaust gas from the combustion chamber 2 by connecting a chimney 24 is formed in the upper part on the rear side of the main body 1.

Furthermore, the main body 1 is provided with an air supply port 30 capable of adjusting the opening degree for supplying air to the combustion chamber 2. A pair of air supply port portions 30 are provided at least on both sides of the front portion of the main body 1 so as to be mirror-symmetric with respect to the axis P of the rod supply body 10. A plurality of pairs (two in the embodiment) of the pair of air supply port portions 30 are provided.
As shown in FIGS. 3A and 4 among the plurality of sets of the air supply ports 30, any one of the air supply ports 30 (A) is a pipe having a circular cross section having an air passage 31. 32, the inlet 33 protrudes to the outside of the front portion of the main body 1, and the outlet 34 thereof is provided on the front side and the lower side of the combustion chamber 2. The inlet 33 is provided with an opening / closing lid 35 that adjusts the opening degree of the inlet 33.

  As shown in FIGS. 3B and 4, any one set of air supply ports 30 (B) includes a pipe 37 having a rectangular cross section having an air passage 36, and its inlet 38. Is a base end portion of the soot supply body 10 and protrudes from the upper portion of the main body 1, and an outlet 39 thereof is provided on the front side and the upper side of the combustion chamber 2. The inlet 38 is provided with a damper 40 for adjusting the opening degree of the inlet 38.

  Therefore, when burning firewood W by this firewood stove S, as shown in FIGS. 1 and 4, firewood W is relatively long, for example, a log, a vertically divided tree, a waste wood of a building, or the like. Prepare 薪 W. In addition, when the length of the kite W is the length which protrudes from the insertion port 12 of the kite supply body 10, it cuts and uses suitably. Of course, even a relatively short soot W can be burned because it falls into the combustion chamber 2 if it is introduced from the inlet 12.

  At first, the lid 15 of the cocoon supply body 10 is opened, and a plurality of these cocoons W are introduced from the insertion port 12 of the cocoon supply body 10 with one end thereof facing down. In this case, since the charging port 12 of the basket supply body 10 is located on the front side of the main body 1, the charging becomes easier than in the case where the charging port 10 is on the side. When the required amount is charged, the lid 15 is closed. In this case, the kite supply body 10 is formed in a cylindrical shape and is inclined, so that the kite W is supported by the wall surface of the kite supply body 10 along the axis P of the kite supply body 10 along its longitudinal direction. One end of the soot W is aligned and supported by the bottom wall of the main body 1 so as to face the combustion chamber 2. When the door 22 is opened, one end portion of the soot W is ignited, and the door 22 is closed again, the combustion chamber 2 burns from one end portion of the aligned soot W. Combustion is performed by changing the opening of the air supply port 30 and appropriately adjusting the amount of air. Combustion gas generated in the combustion chamber 2 is exhausted from the chimney 24. As the soot W burns, the soot W gradually slides and descends along the axis P of the soot supplier 10. During this combustion, since the inlet 12 of the soot supply body 10 is closed by the lid 15, the upper inside of the soot supply body 10 becomes substantially oxygen-free, so that it is positioned on the bottom wall side of the combustion chamber 2. Only one end of the soot W to be burned. For this reason, the soot W does not burn at once, but gradually burns from below, so that the combustion time becomes longer, so that a long time combustion can be obtained with one throw of soot W, and fuel supply management It becomes easy.

  In this case, the ridge W is supported on the wall surface of the ridge supply body 10 along the axis P of the ridge supply body 10 along its longitudinal direction, and one end of the ridge W is aligned and supported on the bottom wall of the main body 1. Therefore, even with a relatively long soot W, the posture becomes regular in the combustion chamber 2, and the soot W is burned uniformly and stably. In this case, since the inclination angle θ of the kite supply body 10 with respect to the horizontal plane is set to θ = 70 ° ± 5 °, the angle is relatively close to a right angle, so that the kite W is substantially upright. Therefore, air easily enters between the soots W, and the soots W can be burned more uniformly and stably.

A pair of air supply ports 30 are provided on both sides of the front portion of the main body 1 so as to be mirror-symmetrical about the axis P of the rod supply body 10, and the pair of air supply ports 30 Since a plurality of sets (two sets in the embodiment) are provided, air is supplied from both sides and a large number of air supply ports with respect to one end portion of the ridge W supported and aligned on the bottom wall of the main body 1. It can be supplied from the parts 30 (A) and (B), so that the air circulation is improved, and the soot W can be evenly and stably burned. In this case, among the plurality of sets of the air supply ports 30, any one of the air supply ports 30 (A) is arranged such that the outlet 34 is positioned on the front side and the lower side of the combustion chamber 2. Since any one set of air supply ports 30 (B) is provided so that its outlet 39 is located on the front side and the upper side of the combustion chamber 2, the air flows from the left and right and up and down. Since it blows with respect to the one end part of the soot W which was supported and aligned by 1 bottom wall, the circulation of air becomes good also in this point, and soot W can be burned more uniformly and stably.
When the bag W disappears, the lid 15 is opened again to replenish the bag W. Moreover, the ash after combustion may be taken out as appropriate provided at the front portion of the main body 1 with the opening 20 opened.

  Examples will now be described. As shown in FIG. 2, the wood stove according to the embodiment has a main body 1 having a width of 500 mm, a length of 400 mm, and a length of 914 mm, and a wood supply body 10 having a diameter of 485 mm and an inclination angle θ = 70 °. The length L of the axis P was set to 900 mm. And 5-6 pieces of soot having an average diameter of 100 mm and a length of 1200 mm were put into the soot supply body 10 as the soot, and the air supply port 30 was appropriately adjusted and burned. The burning time was about 8 hours, and it was confirmed that burning could be performed for a long time.

  In the above-described embodiment, the length of the basket supply body 10 may be changed as appropriate. Also, the overall size may be changed as appropriate. Of course, the number of air supply ports 30 is not limited to the above.
