Referring to FIG. 1, the fireplace 100 of the present invention includes a combustion unit 300, a receiving unit 600, a heat storage unit 400, an oven unit 410, an exhaust unit 500, and an air conditioning unit ( 800 and the air inlet 700, the body portion 200 to protect them and the front of the body portion 200 in the fireplace 100 consisting of a door portion 210, the air inlet 700 ), The first passage 710 for supplying air through the lower portion of the combustion unit 300 and the door 210 and the combustion unit 300 through the upper portion through the rear portion of the combustion unit 300. It comprises a second flow path 720 for supplying air to the.

The appearance of the fireplace 100 may be configured in various ways as needed, but generally composed of a hexahedron or a cylindrical shape, in an embodiment of the present invention will be described with respect to the fireplace 100 made of a hexahedral form.

The fireplace 100 is the heat storage unit 400 and the heat storage unit where the heat generated by the combustion in the combustion unit 300 is concentrated around the combustion unit 300 for burning firewood or fuel, and the heat storage unit Positioned above the 400 is composed of the discharge unit 500 for discharging the heat and smoke generated after combustion.

In addition, the recirculation unit 600 and the combustion unit (300) which can be discarded after storing a predetermined amount of ash generated after the combustion or the process of combustion in the combustion unit 300 downward from the combustion unit 300. Supplying air to the 300 is made of an air inlet 700 to allow combustion to occur.

At this time, the combustion unit 300, the heat storage unit 400, the discharge unit 500, the ash receiving unit 600 and the air inlet 700 is protected from the outside through the body portion 200, One side (front) of the body portion 200 is formed so that the door portion 210 is formed to inject firewood or fuel into the body portion 200, a part of the door portion 210 is inside It will be preferred that the see-through window 220 is provided so that it can be confirmed.

In addition, at the bottom of the combustion unit 300, a lostol 310 having grooves at regular intervals is formed to supply air required for combustion of firewood or fuel from the lower side, and at the same time, ashes generated during the combustion process or afterward fall down. In order to collect ash generated in the combustion unit 300, the ash receiving unit 600 is positioned below the combustion unit 300, and the ash receiving unit 600 is a body part 200 in a sliding manner. ) Is stored.

In addition, an air inlet 700 is provided at a lower end of the ash receiver 600 to supply air necessary in the process of burning firewood or fuel in the combustion unit 300.

The air inlet 700 comprises two (first flow path 710 and the second flow path 720) flow path, the air supplied through the air inlet 700, the combustion unit 300 The first passage 710 for supplying the lower end and the air supplied through the air inlet 700 through the rear of the combustion unit 300 through the upper portion of the combustion unit 300 through the door unit 210. And a second flow path 720 which supplies the combustion part 300. (The routes shown in blue in FIG. 1 are the first and second euros, respectively)

In this case, multiple combustion occurs in the combustion unit 300 through the first passage 710 and the second passage 720, and the air supplied to the second passage 720 is smoke or soot generated during the combustion process. The back does not get on the door portion 210 (more specifically the see-through window 220).

Hereinafter, the multiple combustion and air curtain will be described in more detail.

In general, the burner of the fireplace (100) is open so that the inflow and outflow of air is free combustion method of obtaining a calorie according to the speed or amount of firewood or wood is called general combustion. In the case of general combustion, the thermal efficiency is about 10 to 15%, and thermal energy generated by burning firewood stays in the firebox for a short time, so the thermal efficiency is low.

In order to solve this problem, in one embodiment of the present invention, the air supplied through the second flow path 720 is supplied to the upper layer of the flame to generate multiple combustion. When the air is supplied through the second channel 720 in this way, the combustion temperature is increased by raising the maximum firing point temperature by more than 1000 degrees while causing multiple combustion. In the multi-combustion process, high-temperature combustion is achieved by re-burning combustible wood gas particles that have not yet been burned in soot, ash or smoke. Here, when the air is supplied through the second flow path 720, a bright flame with blue tingling that is separated from the firewood as if floating in the air is a part which can visually confirm that multi-combustion occurs. In the case of combustion, there is also a purpose for obtaining high temperature thermal energy, but the multi-combustion using the air supplied through the second flow path 720 may be referred to as complete combustion or clean combustion because it reduces the amount of carbon monoxide generated.

In addition, in an embodiment of the present invention, the first flow path 710 and the second flow path 720 are formed, and the upper part of the combustion part 300 is not open as it is, and smoke and heat may be discharged. It made the space narrow.

The reason why the space in the upper portion of the combustion unit 300 is narrowly formed is to prevent the heat generated from the combustion unit 300 from escaping to the discharge unit 500 as it is, thereby reducing the heat loss, and the second The air supplied through the flow path 720 is supplied to the door part 210 and the combustion part 300. The supplied air increases the density of the narrow space of the upper part of the combustion part 300, and the density is increased. Elevated combustion gases, flames and air meet to produce multiple combustion.

In this case, the reason for supplying air through the second flow path 720 is as described above in the multi-combustion, when air is supplied toward the narrow space of the upper portion of the combustion unit 300, the combustion unit 300 This is to increase the density of flammable gas consumed and lean in the primary combustion process, and when combustion gas, flame and air of high density meet, multi-combustion occurs as described above. (The path shown in red in Figure 1 is the flow of gas released after combustion)

Here, the air control unit 800 is formed on one side of the body portion 200, the first control unit 810 for adjusting the air supplied to the first flow path 710 and the second flow path 720, respectively ) And the second manipulation unit 820.

However, conventionally, even if the air control using the first control unit 810 and the second control unit 820 can not see the immediate reaction, but the user can check the reaction with the eyes only after a certain time. .

In order to solve this problem, in one embodiment of the present invention, the reaction speed is increased by increasing the speed of air moving through the second passage 720.

In one embodiment of the present invention was configured as follows to increase the speed of the air moving the second flow path (720).

The second flow path 720 is located at the rear of the combustion unit 300, the vertical flow path 721 for moving one side of the outside air entered through the air conditioning unit 800, and the other side of the vertical flow path 721 The inclined flow passage 722 communicating with and having a constant inclination from the rear portion of the combustion portion 300 to the upper portion, and positioned at an upper portion of the combustion portion 300 to communicate with one side of the inclined flow passage 722 to move air. It consists of a horizontal flow path (723).

At this time, the diameter of the vertical passage 721 is configured to be smaller than the diameter of the air control unit 800 (or the second operation unit 820). This can be explained by Bernoulli's theorem.

Bernoulli's theorem is briefly described as follows. One of the fundamental laws of fluid mechanics, published in 1738 by D. Bernoulli. The relationship between speed, pressure and height is defined for the case where the ideal fluid without viscosity and compressibility flows regularly. It is derived from the law that the sum of potential energy and kinetic energy of a fluid is constant. For example, let air flow through a tube of varying thickness and connect a glass tube that goes down a section of different thickness. Observing the height of water in the thin glass tube, the water column connected to the thick side is lowered and the water column connected to the thin side is increased. When the fluid flows at the same height, the velocity of the fluid increases as it flows through narrow passages and decreases as it flows through wide passages. According to Bernoulli's theorem, increasing the speed of fluid lowers the pressure inside the fluid, and conversely, decreasing the speed increases the internal pressure. The higher the pressure, the harder the water column in the glass tube is, because the height of the water column is lowered, and the lower the pressure, the weaker the water column in the glass tube, the height of the water column is increased.

Therefore, the velocity and velocity of the air passing through the vertical flow passage 721 having a smaller diameter compared to the air conditioner 800 is increased in proportion to the width and velocity of the cross section in the layer flow of the fluid.

In addition, as the inclined flow path 722 is formed, the length of the flow path through which air must move as a whole becomes shorter than in the related art.

In detail, referring to FIG. 2, the diameters of the entire flow paths are the same in the related art, and they communicate with each other at right angles.

However, in the exemplary embodiment of the present invention, the vertical air passage 721 configured to be smaller than the diameter of the air control unit 800 (or the second operation unit 820) supplied through the air inlet unit 700 is provided. By moving through, it increases the speed of the moving air.

In addition, the inclined passage 722 is formed between the vertical passage 721 and the horizontal passage 723 to reduce the moving distance and form an inclined surface at the same time compared with the conventional to increase the movement speed of the air.

In order to confirm this through experimental results, the company conducted the following experiment.

Referring to Figures 3 and 4, in one embodiment of the present invention by changing the configuration of the second flow path 720 as described above the reaction rate after operating the air conditioning unit 800 compared to the prior art I confirmed it experimentally.

The experiment was carried out as follows.

By using experimental equipment (manufacturer: YOKOGAWA, NO: S5E204317 2005, MODEL: MV106-3-2-1F, product name: ELECTRICAL HETER) of the conventional fireplace 100 and the fireplace 100 according to an embodiment of the present invention The temperature of the main part was checked.

All other conditions were tested in the same state, and the result of checking the temperature change of the main part after operating the air control unit 800 is as shown in FIG.

Each color in the graph of Figure 4 shows the temperature change of the color corresponding to the portion shown in FIG.

The repetitive experiment result shows that the temperature change occurred after about 10 to 15 minutes after operating the air conditioner 800 in the case of the conventional fireplace 100 (the upper graph of FIG. 4) as shown in FIG. Unlike in the case of the fireplace 100 according to an embodiment of the present invention (the lower graph of FIG. 4), the temperature change was confirmed in about 1 minute after operating the air conditioner 800 in about 10 minutes. As described above, the reaction speed was remarkably faster when the air conditioner 800 was operated by reducing the length of the moving path of the second channel 720 and increasing the moving speed of the moving air by changing the diameter. .

In addition, an oven unit 410 using heat is located in the heat storage unit 400 located above the combustion unit 300. Therefore, an oven door 420 is formed at one side of the body part 200 so that the oven part 410 can be used, and the oven door 420 can view the inside of the oven part 410. 430 is partially formed, and the user may use the oven unit 410 while checking the internal situation of the oven unit 410 through the oven viewing window 430.

In addition, a heat delay plate 440 is provided in a zigzag shape in a passage through which heat is released in order to hold heat as much as possible in order to allow cooking in the oven unit 410.

As described above, the present invention has been described in detail by using a preferred embodiment, but the scope of the present invention is not limited to the specific embodiment, it should be interpreted by the appended claims. In addition, those of ordinary skill in the art, of course, various modifications can be made without departing from the scope and spirit of the present invention.
