Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the appended drawings illustrate the present invention in order to more easily explain the present invention, and the scope of the present invention is not limited thereto. You will know.

3 is a cross-sectional view showing the structure of a stove equipped with a hot water supply function according to the present invention.

As illustrated in FIG. 3, the stove 10 having a hot water supply function according to the present invention includes a main body 11 having a combustion chamber A formed therein and a lower portion of the combustion chamber A, the main body ( And a combustion plate 12 on which the fuel injected through the fuel inlet 40 penetrating the lower inner wall of 11) is placed, and a communication 17 provided on the upper portion of the main body 11 is provided. Here, the fuel inlet 40 is designed in such a way that fuel can be injected into the combustion chamber A without opening the door of the main body 11. On the other hand, as the fuel injected into the stove 10, a petlet may be used. Preferably, the petret uses shaft powder. At this time, the condensed powder is heated to a high temperature of 200 ℃ to 300 ℃ and then dried, by killing the microorganisms and bacteria generated by the microorganism contained in the petlet is a fuel with a strong natural flavor, superior stability.

In addition, a combustion plate 12 having a plurality of redistribution holes 12a is provided in the lower bottom of the combustion chamber A. In addition, a recollection chamber is provided in the lower part of the combustion plate 12, and the recollection chamber 13 is provided in the lower part of the main body 11 in the form of a drawer in this recollection chamber. The lower outer circumferential surface of the main body 11 is provided with a lower cap 16 which is insulated double insulated to block the inflow of air from the outside into the main body 11. Through such a double heat insulating lower cap 16, the fuel material may not leak from the recollecting container to the outside, and air may not be introduced from the outside.

The combustion chamber A inside the main body 11 includes a plurality of curved pipe parts 14a, 14b, and 14c arranged in multiple stages. At this time, the plurality of curved pipe parts 14a, 14b, 14c are each manufactured by winding pipe pipes for circulating water to have a bamboo hat shape. In addition, the plurality of curved pipe parts 14a, 14b, and 14c are connected to each other by a connecting pipe 22, respectively, and are supported by pipe supports (not shown) installed on the inner wall of the main body 11, respectively. In addition, an inlet side of the uppermost bent portion 14a is connected to an inlet tube 21 penetrating through an upper inner wall of the main body 11, and an outlet side end of the lowermost bent portion 14c is connected to the main body 11. Is connected to a drain pipe 23 penetrating the lower inner wall of the upper side of the upper curved pipe portion 14a, the inlet side end of the middle curved pipe portion 14b having an inverted shape, and the middle curved pipe portion 14b. The discharge end of the discharge side and the discharge end of the lowermost bent portion (14c) are each connected by the connecting pipes (22). Here, the plurality of curved pipe parts 14a, 14b, and 14c formed in the combustion chamber A are formed by winding pipe pipes for circulating water supplied through the water inlet pipe 21 in multiple stages. It is apparent that the number and number of arrangement stages of 14b and 14c may be changed by the designer. At this time, the inside of the middle curved pipe portion 14b of the multi-stage is formed with a hot air path having a predetermined radius to serve as a passage for moving the hot air transmitted from the bottom. That is, the air heated from the combustion plate 12 is radiated to the edge of the lowermost bent portion 14c and rises upward through the space formed between the edge and the inner wall of the body, and then the intermediate curved portion 14b with the edge closed. It is raised to the top through the hot stove, and is finally moved to the edge of the uppermost bent portion (14a) is to be moved upward through the space formed between the edge and the inner wall of the body. At this time, due to the flow of hot air, the temperature of the curved tube portion becomes lower than the temperature of the curved tube portion 14c at the lowermost portion. In addition, the uppermost bent portion 14a and the lowermost bent portion 14c are formed in the shape of a hat, so that the time for hot air (indicated by the arrow) from the fuel or the intermediate curved portion 14b to stay therein becomes longer. As a result, the temperature of the water circulating in the curved portion can be increased more quickly.

At this time, the water supply pipe 21 is connected to the water tank 20 in which water is received therein, and receives the water from the water tank 20, the curved pipe parts 14a, 14b, 14c and the connection pipe 22 While circulating, the water circulated as the air of the combustion chamber A is heated by the combustion plate 12 is also heated to become hot water. Then, the hot water is discharged to the outside through the drain pipe 23 to circulate through the storage tank or pipe of the hot water boiler to heat the room or supply hot water.

The combustion plate 12 is connected to an external gas generator 33 ′ and an oxygen generator 33 to receive gas and oxygen from the gas generator 33 ′ and the oxygen generator 33. A spray nozzle 31 for supplying the gas and oxygen in the direction 12) is provided. In more detail, an injection nozzle 31 for injecting gas and oxygen into fuel placed on the combustion plate 12 is installed below the combustion plate 12, and the injection nozzle 31 is a gas supply pipe ( 32 ') and the oxygen supply pipe 32 are connected to the gas generator 33' and the oxygen generator 33. The injection nozzle 31 receives gas and oxygen from the gas generator 33 ′ and the oxygen generator 33 to supply gas and oxygen when the fuel is burned, and the gas supply pipe 32 ′ and the oxygen supply pipe 32. On and off valves 34 and 34 'are provided to supply and block gas and oxygen.

At this time, the on-off valve 34 is composed of an electronic solenoid valve, the solenoid valve is preferably opened and closed by a control unit (not shown) provided outside the main body 11 to facilitate the use of the oxygen supply function. .

In addition, a dispersion plate 37 is provided between the injection nozzle 31 and the combustion plate 12, so that the gas and oxygen injected from the injection nozzle 31 are widely dispersed by the dispersion plate 37 so that the combustion plate 12 is provided. Can be supplied uniformly to the fuel.

The oxygen generator 33 is an apparatus that concentrates about 22% of oxygen by nano-separating nitrogen, which occupies about 78% of external air from the outside of the main body 11. On the other hand, since the oxygen generator 33 is widely used in household water purifiers, air conditioners, vehicle oxygen generators, indoor ventilation oxygen generators, etc., descriptions of the oxygen generation principle and specific configuration of the oxygen generator 33 will be omitted.

On the other hand, if oxygen is not added separately and only the ignition gas without oxygen is injected and the fuel is put into the existing stove to burn, the fuel must pass about 20 seconds of smoke generation time and no smoke is generated after 20 seconds. do. However, when oxygen is introduced into the combustion chamber A through the oxygen generator 33 as in the present invention, there is an effect that smoke is generated only for 5 to 10 seconds after ignition.

Therefore, according to the present stove, it is possible to supply the concentrated oxygen from the oxygen generator 33 to the combustion chamber (A) to completely burn the petret fuel produced in the axial fraction, it is contained in the room due to the carbon generated during fuel combustion Compared to the existing stove that carbonizes the oxygen and causes the oxygen shortage in the room, it is possible to provide an eco-friendly stove that does not require additional indoor oxygen when completely burned.

In addition, assembly lines (not shown) are installed inside and outside the main body 11 so as to be separated into upper and lower parts. At this time, the assembly line may be partitioned only into the upper and lower parts, but is not limited to this, it will be obvious that the position and number of assembly lines can be changed according to the intention of the designer.

According to the present stove having such a configuration, when the fuel of the petret is placed on the combustion plate 12 in the combustion chamber A and ignited, the fuel is burned, and then the on-off valve 34 made of the electronic solenoid valve is opened. In this case, the gas and oxygen generated by the gas generator 33 ′ and the oxygen generator 33 may be supplied to the fuel through the injection nozzle 31 connected to the gas supply pipe 32 ′ and the oxygen supply pipe 32. Therefore, according to the present stove, it is possible to prevent the oxygen contained in the indoor air from using oxygen necessary for combustion of the fuel, and to prevent the oxygen concentration in the indoor air from being insufficient, thereby causing the human body due to lack of oxygen (deficiency). Can prevent the adverse effects of

In addition, since the gas and oxygen injected through the injection nozzle 31 are diffused to the surroundings by the injection plate 37 and supplied to the fuel, the supply of oxygen can be made more uniform, and the injection plate 37 further includes the injection nozzle ( 31, the hole of the injection nozzle 31 can be prevented from being blocked by ash falling into the re-discharge hole 12a of the combustion plate 12.

According to the stove equipped with the hot water supply function configured as described above, by supplying the concentrated oxygen from the oxygen generator 33 to the combustion chamber to completely burn the petret fuel produced by the axial fraction, a plurality of curved pipes ( Since the water circulating 14a, 14b, 14c) is heated with hot water and is supplied to the room, the oxygen supply function prevents the lack of oxygen in the room to make the indoor environment comfortable and at the same time supply hot water to the room. . In particular, the stove equipped with the hot water supply function is inefficient because the conventional stove takes a long time to increase the room temperature, but when installed on the wall or floor of the room in consideration of the efficiency of the hot water line, the thermal expansion index Can increase 40-50% of existing stoves.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

Therefore, the exemplary embodiments described above are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the following claims rather than the detailed description, and the meaning and scope of the claims and their All changes or modifications derived from equivalent concepts should be construed as being included in the scope of the present invention.
