Abstract

PROBLEM TO BE SOLVED: To provide a wood stove capable of preventing smoke from being generated under fumigation of wood when the wood is placed on flaring above a bottom plate of a combustion chamber.SOLUTION: A wood stove 10 forms a space 40 between a bottom plate 28 and a wood 12 by forming protrusions 38 at a bottom plate 28 of a combustion chamber 14. It is possible to keep flaring 42 in the combustion chamber 14 until the flaring 42 is completely burnt without being dropped onto an ash receiver 22 by sliding a lower plate 32 of the bottom plate 28, closing holes 36 of an upper plate 30, and keeping the combustion chamber 14 to a tight-sealed state. In addition, since it is possible to make much flaring 42 on the bottom plate 28, it is possible to keep the combustion chamber 14 at a high temperature to cause the protrusions 38 to be heated. At this time, it is possible to wrap immediately the wood 12 placed on the bottom plate 28 with flame by feeding primary combustion air 16 to the space 40 between the bottom plate 28 and the wood 12, thereby preventing smoke from being generated.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a soot stove for burning soot in a combustion chamber of the stove.

In recent years, the number of lovers of wood stoves has increased. However, when using a wood-burning stove in a residential area or the like, there is a problem that the smoke discharged from the wood-burning stove becomes a nuisance to the neighborhood.
As a solution to the above problem, it is conceivable to install the chimney at a high position. However, smoke may be carried to the living area of other people by the airflow of the outside air, so it cannot be said that it is an effective solution.

  When soot is completely burned in the combustion chamber of the wood stove, no smoke is emitted from the chimney of the wood stove, and therefore, there is currently provided a smokeless wood stove that does not emit smoke from the chimney (for example, Patent Document 1). ).

  In the wood stove of Patent Literature 1, a wood pillow extending in the width direction of the main body is fixed to the bottom plate in the vicinity of the wood inlet while the vertical cross-sectional shape has a bent portion and forms a turn from the bottom plate to the rear plate. ing. This saddle pillow is a part of the saddle that is placed and supported by being inclined to the bottom plate. A gap is formed between the saddle and the bottom plate to circulate air around the entire saddle. As a result, combustion efficiency can be improved.

  However, in the soot stove of Patent Document 1, since a part of the soot is placed on the soot pillow and inclined to the bottom plate to support the soot, the whole soot is not placed on the fire on the bottom plate of the combustion chamber. For this reason, even if a soot was placed on the bottom plate, the flame did not rise immediately, and there was a risk that the soot would be smoked to generate smoke.

  The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a soot stove capable of preventing soot from being smoked when smoke is placed on a fire on the bottom plate of a combustion chamber. To do.

  The wood stove of the present invention comprises a bottom plate for placing the soot in the combustion chamber and an ash receiving portion below the bottom plate, and the bottom plate is composed of two flat plates that are stacked one above the other. A hole is provided on the upper plate for dropping ash to the ash receiving portion, and a plurality of protrusions are provided on the upper surface of the upper plate. A hole for dropping ash on the ash receiving portion is provided on the lower plate, and the lower plate is It is provided so as to slide forward and backward along the lower surface of the plate, and the lower plate is slid to open and close the hole in the bottom plate.

  The soot stove of the present invention improves combustion efficiency by providing a space between the bottom plate of the combustion chamber and the soot placed on the top surface thereof. Thereby, soot can be burned completely and it can prevent that smoke generate | occur | produces.

It is a figure showing the wood stove of this invention. It is a figure showing the baseplate of the combustion chamber of the wood stove of this invention. It is a figure showing the state which opened the hole of the bottom plate of the fuel chamber of FIG.

  The present invention realizes complete combustion of soot by providing an air passage between the bottom plate of the combustion chamber and the soot placed on the bottom plate.

The wood stove of the present invention will be described with reference to the drawings. FIG. 1 is a view showing a wood stove according to the present invention, and is a view showing a state in which a hole of a bottom plate of a fuel chamber is closed. FIG. 2 is a view showing a bottom plate of a combustion chamber of a wood stove according to the present invention. FIG. 2 (a) is a plan view of a firewood mounting portion of the wood stove of the present invention, and FIG. 2 (b) is a plan view of an ash discharge portion. It is. FIG. 3 is a view showing a state in which a hole in the bottom plate of the fuel chamber of FIG. 1 is opened.
The soot stove 10 of the present invention includes a combustion chamber 14 for burning the soot 12, a first combustion air intake 18 for sending primary combustion air (outside air) 16 to the combustion chamber 14, and an ash 20 (see FIG. 3) It has the ash receiving part 22 which receives, and the discharge part (chimney) 26 which discharges | emits the gas 24 of the combustion chamber 14 outside. The ash receiving part 22 is provided with an ash receiving tray 22a.
The soot stove 10 includes a bottom plate 28 for placing the soot 12 in the combustion chamber 14, and the bottom plate 28 is formed of two flat plates 30 and 32 that overlap vertically (FIGS. 1 to 3). As shown in FIGS. 1 and 3, the upper plate saddle mounting portion 30 is fixed to a body 34 that forms the combustion chamber 14. The lower plate ash discharge portion 32 is provided so as to be slidable forward and backward of the combustion chamber 14 along the lower surface of the soot mounting portion 32. The bowl mounting part 30 and the ash discharge part 32 are provided with a hole 36 having the same form (FIGS. 2A and 2B). By sliding the ash discharge part 32 and communicating the hole mounting part 30 and the hole part 36 of the ash discharge part 32, the hole part 36 of the bottom plate 28 can be opened. The ash 20 can be discharged to the ash receiving part 22 (FIG. 3). Further, by not allowing the soot placement part 30 and the hole part 36 of the ash discharge part 32 to communicate with each other, the hole part 36 of the bottom plate 28 can be closed, and the combustion chamber 14 can be sealed (FIG. 1).
The first combustion air intake 18 is formed in the body 36 of the wood stove 10 at a position higher than the bottom plate 28.

The eaves mounting part 32 is provided with a projection 38 on the upper surface thereof. The protrusions 38 shown in FIGS. 1 to 3 are cylindrical, but are not limited to this form. A plurality of protrusions 38 are provided on the upper surface (portion where the hole 36 is not formed) of the saddle placement unit 30 (FIG. 2A). It is provided so that the space 40 used as the passage of air may be formed between the mounting part 30 and the cage | basket 12 (FIG. 1).
Moreover, when the ash discharge part 32 is slid and the hole part 36 of the bottom plate 28 is closed (FIG. 1), the combustion chamber 14 is in a sealed state, so that the bonfire (embers) 42 does not fall into the ash receiving part 22 and the bottom plate Many bonfires 42 can be created on 28. In addition, the bonfire 42 a that has entered the hole 36 of the soot placement unit 30 can also remain in the combustion chamber 14 until it completely burns (until it becomes ash). Furthermore, since the protrusion 38 is heated to a high temperature by the heat of the bonfire 42, the combustion chamber 14 can be kept at a high temperature.
Therefore, according to the soot stove 10 of the present invention, many fires 42 can be created and the combustion chamber 14 can be kept at a high temperature. Therefore, by sending the primary combustion air 16 into the space 40 of the bottom plate 28, the soot 12 is immediately It can be wrapped in flames and smoke generation can be prevented.

  When the temperature of the combustion chamber 14 is low or when there is little bonfire 42, even if the soot is placed on the bottom plate 28, the flame does not rise and incomplete combustion occurs and smoke is generated.

  In the soot stove of the present invention, the combustion chamber can be kept at a high temperature and air (oxygen) can be sufficiently supplied to the combustion chamber. Therefore, when the entire soot is placed on the fire on the bottom plate of the combustion chamber, It is possible to prevent smoke from being generated.
