Description

Self-repeating combustion stove

The present invention relates to an automatic repeat-burning stove, and more particularly, to an automatic repeat-burning stove capable of completely burning a combustible material to increase thermal efficiency and reduce the amount of combustible material used.

In general, a stove is a device that obtains light and heat by burning carbon organic compounds. In particular, a wood stove is used by 70% of the world's population for cooking and heating, and in Korea, it is used every winter in rural areas.

Most of these wood stoves are configured such that the mounting, which is a combustible object, burns only once, and the combustion gas generated by combustion is discharged to the outside through the chimney. As a result, the consumption of combustible materials, which are firewood, increases, and resources are wasted.

Accordingly, after primary combustion, air is introduced again to cause secondary combustion, or a stove including a configuration for allowing the burned heat to stagnate using a plate or space has been released. However, even if air is introduced again, complete combustion cannot be achieved. As a result, a large amount of pollutants such as carbon dioxide and harmful gases are discharged to the extent that incomplete combustion occurs, and consumption of the combustible is inevitably increased.

The scope of the present invention is not limited to the embodiments described below, and various modifications may be made by those of ordinary skill in the art without departing from the technical gist of the present invention.

Hereinafter, an automatic repeat combustion stove according to the present invention will be described in detail with reference to the accompanying FIGS. 1 to 5 .

The present invention's automatic repeat combustion stove, as shown in FIGS. 1 to 5, includes a combustion chamber 100, an inlet pipe 200, and an outer cylinder 300, providing warmth as the object 10 is burned. It is configured so that it can be, and the to-be-combusted object 10 in the present invention is described on the premise that it is firewood, but is not necessarily limited thereto.

The combustion chamber 100 has an empty cylinder shape inside, and may be formed in a cylindrical shape having a polygonal cross-section, but it is preferable to have a cylindrical cross-section in consideration of the smooth flow of air inside. . In addition, a communication 120 is provided above the combustion chamber 100 while communicating with the interior at the upper portion of the combustion chamber 100 so that the combustion gas inside the combustion chamber 100 is discharged to the outside through this. As will be described later, the combustion gas discharged through the flue 120 means a combustion gas composed of carbon dioxide gas and water vapor in which complete combustion has been achieved.

In addition, the communication opening/closing port 121 for controlling the exhaust gas emission to the outside may be provided in the communication unit 120 , and the user may close or open the communication unit 120 by manipulating the communication opening/closing port 121 . This may cause the flame to soar through the inlet pipe 200 as it is operated together with the ignition port 130 to be described later. As an example, in the present invention, the communication opening/closing port 121 is operated in the operating state to close the communication unit 120, and as the ignition port 130 is opened so that external air is introduced through the ignition port 130, the inlet pipe ( 200) to make the fire soar. Accordingly, the user may place a pot stand on the upper surface of the combustion chamber 100 and cook using the soaring flame.

The inlet pipe 200 is made in the form of a tube having a smaller diameter than the combustion chamber 100 , is fixed to the upper end of the combustion chamber 100 , and is provided at the inner center of the combustion chamber 100 . The combustion target 10 is put into the inside of the inlet pipe 200 , and it is preferable that the upper end of the inlet pipe 200 protrude from the upper surface of the combustion chamber 100 . In addition, the lower end of the inlet pipe 200 is provided to be spaced apart from the bottom surface of the combustion chamber 100 to form a primary combustion space below the inlet pipe 200 .

At this time, the combustible object 10 positioned on the bottom surface of the combustion chamber 100 among the incombustible objects 10 injected into the inlet pipe 200 may be ignited in the lower portion of the combustion chamber 100 . To this end, an ignition port 130 may be provided at the lower end of the combustion chamber 100 to ignite the combustion target 10 located on the bottom surface of the combustion chamber 100 from the outside. As an example, the ignition sphere 130 is configured in a drawer type from the lower side of the inlet pipe 200 , and by drawing the ignition sphere 130 to the outside, it is possible to ignite the combustible object 10 accommodated in the ignition sphere 130 . As another example, the ignition port 130 is formed to extend from the lower end of the combustion chamber 100 that is below the inlet pipe 200 to be described later to the outside of the outer cylinder 300 to be described later, and the portion located outside the outer cylinder 300 is Since the bar may be configured to be opened and closed, the combustible object 10 positioned at the lower end of the combustion chamber 100 may be ignited using an ignition tool in a state in which the outer portion of the outer cylinder 300 is opened.

In addition, the inlet pipe 200 serves as a passage for continuously supplying air required for primary combustion while providing a passage through which the to-be-combusted object 10 is input. Therefore, in order to smoothly supply air from the outside to the lower part of the combustion chamber 100 through the inlet pipe 200, the inlet pipe 200 includes an upper inlet pipe 200a and a lower inlet pipe as shown in FIG. 2 . (200b) may be included.

At this time, the lower inlet pipe 200b is formed to extend downward from the lower end of the upper inlet pipe 200a to communicate with the upper inlet pipe 200a, and to have a smaller diameter than the upper inlet pipe 200a. Accordingly, since the air flow in the lower inlet pipe 200b is faster than the air flow in the upper inlet pipe 200a, air is smoothly supplied from the outside toward the lower part of the combustion chamber 100 . In addition, it is preferable that the portion where the upper inlet pipe 200a and the lower inlet pipe 200b are connected is formed such that the diameter is gradually reduced, so that the flow of air moving downward is not interfered by the corresponding part. .

The outer cylinder 300 is configured to be supported on the ground while surrounding the side surface of the combustion chamber 100 . As an example, the outer cylinder 300 is provided so as to be spaced apart from the side wall of the combustion chamber 100 while forming a cylinder shape with a side wall larger than the diameter of the combustion chamber 100 as shown in FIGS. 1 and 2, and the outer cylinder 300 The upper surface extending upward from the side wall is formed to gradually decrease in diameter as it goes upward, so that the upper end may be coupled to the middle portion of the combustion chamber 100 . In addition, the outer cylinder 300 may be configured such that the lower side is opened to be supported on the ground by the side wall, and at this time, the combustion chamber 100 has a bottom surface spaced apart by a predetermined height from the lower end of the side wall of the outer cylinder 300 . can be located.

In the present invention as described above, as shown in FIG. 3 , the combustion gas generated as the to-be-combusted object 10 is ignited in the lower part of the combustion chamber 100 circulates in the combustion chamber 100 and the inlet pipe 200 . It is designed to be completely combustible.

To this end, as shown in FIG. 2 , a first inlet hole 210 is formed through the inlet pipe 200 to communicate with the combustion chamber 100 , and the combustion chamber 100 has a lower side than the first inlet hole 210 . The second inlet hole 110 is formed to communicate with the outer tube 300 in the through, and the third inlet hole 310 is provided at the lower side of the outer tube 30) to communicate with the outside than the second inlet hole 110. penetration is formed. Accordingly, as shown in FIG. 3 , the combustion gas generated by the ignition of the combustible object 10 is moved upward through the space between the inlet pipe 200 and the combustion chamber 100 to the first inlet hole 210 . It is introduced into the inlet pipe 200 through the inlet pipe 200, and the external air descends to the lower part of the combustion chamber 100 along the flow moving downward through the inlet pipe 200, and combustion is performed again.

In the process in which the combustion gas circulates in the combustion chamber 100 and the inlet pipe 200 through the first inlet hole 210, as shown in FIG. 3, the third inlet hole 310 and the second inlet hole ( Secondary combustion is made in the vicinity of the second inlet hole 110 is formed by the external air introduced into the combustion chamber 100 through 110), and the first by the external air introduced through the upper end of the inlet pipe 200 Third combustion is made in the vicinity of the inlet hole 210 is formed. As described above, in the present invention, as the combustion gas is continuously circulated, repeated continuous combustion is performed by external air, and the combustion gas in which complete combustion is achieved is discharged through the flue 120 . Therefore, complete combustion of the combustible material 10 is achieved, so that not only can the thermal efficiency be increased, but also the amount of the combustible material can be reduced, which is economical.

And the first inlet hole 210 , the second inlet hole 110 , and the third inlet hole 310 are a plurality of the inlet pipe 200 , the combustion chamber 100 , and the outer cylinder 300 at regular intervals along the circumference, respectively. It is preferred that dogs are formed. In this case, the first inlet hole 210 and the second inlet hole 110 may be formed such that vortices rotating in opposite directions are formed in the inlet pipe 200 and the combustion chamber 100 .

For example, the first inlet hole 210 is formed to pass through the inner circumferential surface from the outer circumferential surface of the sidewall of the inlet pipe 200 as shown in FIGS. 4 and 5A , and is on the right side of the reference line toward the center of the inlet pipe 200 . It may be formed so as to penetrate the inner circumferential surface to be distorted by a predetermined angle. In the inlet pipe 200 in which a plurality of such first inlet holes 210 are formed, a vortex rotating counterclockwise is formed in the vicinity of the first inlet hole 210 . Combustion gas introduced through the external air and the first inlet hole 210 is directed toward the lower portion of the combustion chamber 100 while forming a downdraft.

The first inlet hole 210 is formed at the upper end of the lower inlet pipe 200b, which is a point at which the air flow is accelerated by reducing the width compared to the upper inlet pipe 200a, so that a strong downdraft is formed. do.

And as an example, the second inlet hole 110 is formed to pass through the inner circumferential surface from the outer circumferential surface of the side wall of the combustion chamber 100 as shown in FIGS. 4 and 5B, and to the left of the reference line toward the center of the combustion chamber 100 It may be formed so as to penetrate the inner circumferential surface to be distorted by a predetermined angle. In the combustion chamber 100 in which a plurality of such second inlet holes 110 are formed, a vortex rotating in a clockwise direction is formed in the vicinity of the second inlet hole 110 , and the outside introduced through the second inlet hole 110 . Air and the combustion gas in which the primary combustion is made is directed upwards of the combustion chamber 100 while forming an upward airflow.

On the other hand, the present invention is configured to smoothly send the combustion gas to the vicinity of the second inlet hole 110 so that secondary combustion is made, and may further include an upward thrust plate 400 . As an example, the upward propelling plate 400 may form a curved surface extending from the lower end of the inlet pipe 200 toward the outside upward, as shown in FIG. gap becomes narrower. Accordingly, the combustion gas in which the primary combustion has occurred in the lower portion of the combustion chamber 100 is accelerated while moving upward on the upward propelling plate 400 as shown in FIG. 3 .

At this time, the second inlet hole 110 is formed near the upper end of the upward thrust plate 400 so that a vortex is formed at a point where the flow of combustion gas has a relatively high speed, thereby forming a strong upward airflow. It is preferable to

As such, the present invention may further include a rising delay plate 500 so that combustion gas that is not completely combusted among the combustion gases moving in the strong upward airflow can be smoothly introduced into the first inlet hole 210 . As an example, the rising delay plate 500 may form a curved surface extending from the upper side of the first inlet hole 210 toward the outer and lower sides as shown in FIG. The spaced distance becomes narrower.

The rising retardation plate 500 serves to delay the rise of the combustion gas, and the combustion gas, which is relatively heavier than the completely burned combustion gas because complete combustion is not achieved, passes through the inlet pipe through the first inlet hole 210 . (200) serves to flow in. At this time, the combustion gas in which complete combustion is made passes between the rising retardation plate 500 and the side wall of the combustion chamber 100 and flows into the communication tube 120 and is discharged to the outside.

On the other hand, as an upward airflow is formed in the space between the combustion chamber 100 and the inlet pipe 200, in order to prevent the heat from rising together and escaping to the outside, the present invention provides the combustion chamber 100 and the inlet pipe 200, respectively. It may further include a configuration for delaying the opening on top of the. As an example, as shown in FIGS. 2 and 3 , a first heat delay plate 610 having an outer periphery coupled to the upper inner wall of the combustion chamber 100 while forming a ring shape having a predetermined width, and a first heat delay While forming the same shape as the plate 610, the inner periphery may further include a second heat delay plate 620 coupled to the upper portion of the inlet pipe 200, that is, to the outer wall of the upper inlet pipe 200a.

At this time, the first heat delay plate 610 is formed so that the inner periphery is spaced apart from the inlet pipe 200, the second heat delay plate 620 is formed so that the outer periphery is spaced apart from the combustion chamber 100, complete combustion The formed combustion gas forms a path that can move to the flue (120).

Since the flow of air passing through the first heat delay plate 610 and the second heat delay plate 620 forms a zigzag shape, the heat escapes to the outside is delayed for a certain time, so that the warmth is more continuously can be maintained for a long time.

And the present invention may further include a cover 700 for sealing the upper end of the inlet pipe 200 as shown in FIG. The cover 700 is to prevent the inflow of external air through the inlet pipe 200 so that ignition can be performed quickly. After covering 700, the combustible object 10 is ignited using an igniting agent or a torch through the ignition port 130, and after a certain period of time, the cover 700 is opened so that repeated and continuous combustion of the combustion gas is made. can do.

The process of burning firewood (firewood) as a to-be-burned object in the present invention as described above is as follows.

1) Put firewood into the inlet pipe 200 through the upper end of the inlet pipe 200 and seal the upper end of the inlet pipe 200 with a cover 700 .

2) Ignite the firewood through the ignition hole 130 . At this time, the generated combustion gas cannot escape to the outside through the inlet pipe 200 , and is accelerated by the upward thrust plate 400 and moved upward.

3) The combustion gas moved to the vicinity of the second inlet hole 110 along the upward thrust plate 400 is caused by external air introduced from the outside through the third inlet hole 310 and the second inlet hole 110 . Secondary combustion is triggered. At this time, the inlet pipe 200 is opened by sealing the ignition port 130 and removing the cover 700 . Due to this, the outside air is introduced through the inlet pipe 200 and the firewood starts to be burned in earnest from the bottom.

4) The combustion gas rising after the secondary combustion is delayed through the rising delay plate 500 , and the combustion gas having a large mass is introduced back into the inlet pipe 200 through the first inlet hole 210 , Third combustion occurs. This is possible using the Bernoulli principle using the difference between the speed at which external air is introduced through the inlet pipe 200 and the speed of the combustion gas delayed by the rising delay plate 500 . At this time, the first inlet hole 210 is formed at the upper end of the lower inlet pipe 200b, which is smaller in width than the upper inlet pipe 200a, to increase the inflow rate of external air, so that the combustion gas is passed through the first inlet hole 210. can promote the influx of

5) The combustion gas in which the tertiary combustion is made is again moved to the lower part of the inlet pipe 200, and the above process is repeatedly performed together with the combustion gas newly in the primary combustion, so that complete combustion is achieved.
