Description

Wood stove {Wood stove}

The present invention relates to a wood-burning stove that has a low risk of fire, stably maintains heat power and heat retention, smoothly discharges smoke and combustion gases, and can cook various foods requiring high heat.

In general, firewood stoves, unlike gas stoves and oil stoves, are devices for heating by burning firewood, and their use is increasing in rural areas and as camping equipment.

A conventional firewood stove has a combustion chamber of a certain size so that firewood can be easily burned, an air hole communicating with the combustion chamber so that outside air can flow in well, and the combustion chamber so that smoke generated in the combustion process can be discharged smoothly. It consists of a communication connected with

However, in the conventional wood-burning stove, the flame in the combustion chamber is frequently discharged through the chimney due to its strong thermal power, so the risk of fire is very high and the combustion heat is directly discharged through the chimney, limiting the ability to increase heat retention and heating efficiency. There was a problem that there was.

In addition, the conventional firewood stove has a problem that the firepower can be maintained only by continuously forcibly injecting outside air, and the exhaust power is weak, so the smoke and combustion gases generated in the combustion process are not smoothly discharged through the flue, so they flow backward. . In order to prevent this, there is an inconvenience that a separate forced exhaust fan must be installed.

Recently, a firewood stove that provides a cooking space for cooking food is also known, but there is a limitation in that food requiring high heat cannot be cooked because the cooking space is exposed to the outside.

The overturning portion 310 is formed to protrude upward at the front end of the horizontal lower portion 320, and has a relatively narrow flow path compared to the combustion chamber 200 so that the heat in the combustion chamber 200 burns quickly and strongly. Provides a step.

Therefore, the heat of the combustion chamber 200 cannot easily move to the flue 300 by the overflow portion 310 and accumulates inside the combustion chamber 200 for a long time, while the convective atmospheric pressure between the combustion chamber 200 and the flue 300 As the vehicle is formed, hot air from the combustion chamber 200 is naturally discharged to the flue 300 without a separate forced exhaust device.

On the other hand, the flue 300 may include at least one partition 350 dividing the overturning portion 310, the lower horizontal portion 320, the vertical portion 330, and the upper horizontal portion 340 into two sides.

In this case, since the flue 300 has a narrowed passage by the partition 350, the movement speed of the hot air increases.

In addition, a partition cutoff portion 360 may be formed at each boundary section between the lower horizontal portion 320, the vertical portion 330, and the upper horizontal portion 340.

The partition cutoff 360 is an empty space in which the partition 350 is not installed, and as the heat escaping from each partition 350 in the partition cutoff 360 is mixed, a vortex is generated due to different temperature and pressure differences. generated, and due to the vortex, the discharge speed of the hot air is further increased.

Meanwhile, a heat dissipation member 370 may be further provided at the lower part of the flue 300 to block heat from the lower horizontal part 320 to prevent fire or burn hazard. The heat dissipation member 370 is not limited in its material or shape.

The communication pipe 400 is coupled to the end of the horizontal upper part 340 of the flue 300.

The oven 500 has a front surface made of the rear surface of the main body 100 and a rear surface made of the vertical portion 330 of the flue 300 so as to simultaneously receive hot air from the main body 100 and the flue 300. It consists of the horizontal lower part 320 of the flue 300 and the upper surface is composed of the horizontal upper part 340 of the flue 300.

In addition, an opening and closing door 510 is installed on one side of the oven 500 to form an enclosed space, and a cover panel 520 is attached to the other side.

The operation of the firewood stove of the present invention configured as described above will be described.

First, when the combustion chamber door 140 is opened, firewood is put into the combustion chamber 200 and firewood is ignited, and then the combustion chamber door 140 is closed, the outside air flows into the combustion chamber 200 through the first outside air intake hole 112. After entering the inside of the first outdoor air inlet 111 formed on both sides, the temperature rises due to the heat of the combustion chamber 200 .

The outdoor air whose temperature has risen rises along the first outdoor air inlet path 111 and then is discharged into the combustion chamber 200 through the second outdoor air inlet hole 113 .

Therefore, the firewood stove of the present invention is convenient to use because combustion is continuously and smoothly performed without forced external air supply, and accordingly, the combustion chamber door 140 does not have to be opened frequently, thereby minimizing the emission of smoke or combustion gas to the outside. be able to

In addition, smoke and combustion gas, including heat in the combustion chamber 200, are discharged to the flue 300 through the heat discharge hole 130, and the discharge of smoke and combustion gas, including this heat, is discharged through the overflow portion of the flue 300 ( 310), it is smoothly performed without a separate forced exhaust device due to the convection air pressure difference.

In particular, hot air having different temperatures and pressures exiting each partition 350 of the flue 300 is mixed at the partition cutoff 360 formed in the flue 300 to generate a vortex, and due to the vortex As the emission speed is improved, the emission of heat, smoke and combustion gases is more smoothly. Smoke and combustion gas including hot air passing through the flue 300 are all discharged to the outside through the flue 400 .

In addition, heat from the combustion chamber 200 is not directly discharged through the communication 400 by the overflow portion 310 and is accumulated in the combustion chamber 200, so heat retention and heating efficiency are greatly improved.

On the other hand, the hot air exiting the combustion chamber 200 continuously provides heat to the furnace 500 and the auxiliary furnace 600 while moving along the flue 300, and at the same time, the main body 100 also continuously moves along the furnace 500. ) And since heat is provided to the auxiliary stove 600, the thermal efficiency of the stove 500 and the auxiliary stove 600 is maximized.

Accordingly, the user can cook various menus of food requiring a high cooking temperature using the oven 500 and the auxiliary oven 600 .

As a result, the heat escaping from the combustion chamber 200 is sufficiently heat-exchanged with the flue 300 and the furnace 500 in the process of moving along the flue 300, and the temperature drops significantly when it reaches the flue 400. No risk of fire.

As such, although the preferred embodiments of the present invention have been shown and described with reference to the drawings, they can be modified and changed in various ways without departing from the spirit or field of the present invention provided by the claims below, which also It should be included in the scope of the present invention.
