Generally, briquette is less clean than other heat sources, but its economy is very high. It is used not only for farmhouses such as greenhouses, flower farms, poultry farms, but also for large houses and restaurants as indirect heating by direct heating or boiler.

However, the amount of heat is not very high as compared with other energy sources including fossil fuels such as liquid or gaseous fuels, and there are restrictions on the combustion conditions, which is inconvenient to use. That is, the number of times the briquette is usually changed once a day is suitable, but when the combustion condition is insufficient, the cycle is shortened and even the fire is likely to be turned off in the middle. As a result, it greatly affects the yield and quality in the life of crops and flowers.

Nevertheless, since coal is a long-term resource, considering its reserves, compared to oil and gas, it is inevitable that it will continue to be used and used as an application that requires economic efficiency unless other alternative energy sources are developed.

The supporting member 12 may be made of briquettes or a twin screw, and may be provided with a burner or the like for burning the liquid fuel. In order to use the liquid fuel or the harmonics as the fuel, the support member 12 or the intermediate member 14 may be provided with a door capable of receiving a harmony and a structure in which the burner connection pipe can be installed.

However, the present embodiment will be described on the basis of the use of briquettes as fuel.

On the other hand, a lid is provided on the upper part of the upper member 18. This lid is intended to prevent the gas generated by the combustion of the fuel from flowing out. This lid may not be used when raising the temperature of the hot water stored in the lid hot water tank 24 quickly and high. This is to allow the heat of the fuel to directly heat the lid warm water tank 24.

The supporting member 12 is provided with a combustion section 12A for burning fuel. The combustion section 12A has a net structure, and the ash generated by the combustion falls to the ash tray, and also serves to supply air required for combustion. To this end, the ashtray may be provided with an air control valve.

Each of the components of the stove unit 10 is coupled to each other by bolts or the like with a gas-tight member or the like interposed therebetween. This is so that the gas generated during the combustion process of the fuel is discharged only through the communication pipe.

And a communication base 44 for supporting the communication 40. The upper end of the communication bracket 44 is coupled to the lower portion of the communication pipe 40 and the lower end of the communication bracket 44 is fixed to the outer surface or the bottom edge of the receiving member 12. The communication pipe 40 is integrally formed with the communication preheating portion 50, .

Such a hot water tank 22 encloses the intermediate member 14 of the hearth section 10, so that heat loss of the intermediate member 14 is prevented. This is because the hot water tank 22 serves as a heat insulating case.

The lid warm water tank 24 is installed on the upper surface of the heating water tank 32 by a hinge. The lid hot water tank 24 can open and close the upper portion of the heating water tank 32 by the hinge, so that the briquettes of the hearth portion 10 can be replaced.

The lid warm water tank 24 is for heating the hot water by the heat moving upward in the hot water tank 22 and the heating water tank 32.

The lid hot water tank 24 and the hot water tank 22 are connected by a connecting pipe as shown in Figs. That is, the hot water outlet 22B and the inlet of the lid hot water tank 24 are connected to each other by a pipe so that the hot water of the hot water tank 22 is heated and then circulated to the lid hot water tank 24. Since the outlet of the lid hot water tank 24 is connected to the inlet of the hot water circulation tank 54 by the pipe, the hot water of the lid hot water tank 24 can be circulated to the hot water circulation tank 54.

The auxiliary tank (60) has a water supply valve (64) for opening and closing the water pipe (62) when the water level is lowered by the use of hot water. The water supply valve 64 has a buoyant body 64A provided inside the auxiliary tank 60 and one end connected to the buoyant body 64A and the other end connected to the outlet of the water pipe 62, And an opening and closing member 64B that closes the water pipe 62 when the air bag 64A ascends and opens the water pipe 62 when the buoyant member 64A descends.

On the other hand, the hot water inlet 22A of the hot water tank 22 is provided with a three-way connection pipe 22C. One end of the three-way connection pipe 22C is coupled to the hot water inlet 22A and the other end is connected to one end of the branch pipe 54A of the hot water circulation tank 54 by a pipe. A one-way valve 22D is installed in the other end of the one end connected to the branch pipe 54A and the other end connected to the auxiliary tank 60 . Therefore, the replenishing water flowing from the auxiliary tank 60 and the hot water flowing from the hot water circulation tank 54 flow into the inlet 22A only.

The heating water heating unit 30 is formed in a circular or polygonal hollow shape having a predetermined thickness so that the upper member 18 is inserted in the center and has a heating water inlet port 32A and a heating water outlet port 32B And a heating water tank 32 coupled to the upper surface of the hot water tank 22.

The heating water outlet 22B is connected to a heating pipe 70 disposed in the heating space and the heating water outlet 32B is connected to a temperature switch 32C and a temperature switch 32C for measuring the temperature of the heating water And a heating water circulation pump 32D that is operated to circulate the heating water to the heating pipe 70 or to stop the circulation thereof is installed.

Since the heating water tank 32 is formed into a cylindrical or polygonal hollow shape having a constant thickness like the hot water tank 22, the stove portion 10 is located at the center, do. This heating water tank 32 encloses the intermediate member 14 of the hearth section 10, so that the heat loss of the intermediate member 14 is prevented. This is because the hot water tank 22 serves as a heat insulating case.

The hot water tank 22 and the hot water tank 32 described above move downward from the upper portion so as to enclose the intermediate member 14 and the upper member 18 after all of the stove parts 10 are joined, 10). At this time, the hot water tank 32 is seated on the upper surface of the hot water tank 22 so as to be in contact with each other. This is to prevent the heat from flowing between the hot water tank 22 and the hot water tank 32. Since this structure and the lid hot water tank 24 cover the heating water tank 32, a separate heat insulating means is not required for the stove part 10. [

The communication preheating section 50 preheats the heating water and at the same time, the hot water heated in the hot water tank 22 and the lid hot water tank 24 is circulated again while preheating the heating water. The lower end is connected to the installation hole 14A A heating water preheating tank 52 which is connected to the heating water tank 32 and surrounds the communication pipe 40 so that the stored heating water is preheated by the heat of the exhaust gas passing through the communication pipe 40, And a hot water circulation tank 54 connected to the lid hot water tank 24 and the hot water tank 22 and covering all areas except the bottom surface of the heating water preheating tank 52 and a partial area of the communication pipe 40.

The communication preheating section 50 is formed integrally with the communication pipe 40 and the heating water preheating tank 52 and the hot water circulation tank 54. This is because the communication preheating section 50 is coupled to the communication pipe 40, This is to eliminate the hassle of doing so. Therefore, it is needless to say that additional communication is connected to the upper and lower ends of the communication pipe 40.

The communication preheating portion 50 thus integrally formed will be described in detail.

The heating water preheating tank 52 is configured to enclose the communication pipe 40 and is connected to the number of heating water inlet ports 32A of the heating water tank 32 by the connection pipe and the heating water circulated through the heating pipe 70 And is connected to the end of the heating pipe 70 so as to flow into the heating water preheating tank 52 again.

The hot water circulation tank 54 is configured to enclose the heating water preheating tank 52 and a part of the communication pipe 40 so that the hot water can be heated by the exhaust gas passing through the communication pipe 40, 52 to prevent the heat loss of the heating water contained in the heating water from being generated and to heat the heating water to raise the temperature.

At this time, the hot water circulation tank 54 is connected to the hot water tank 24 by the connection pipe, and is connected to the hot water inlet 22A by the connection pipe so as to circulate the hot water tank 22 again.

On the other hand, the heating water preheating tank 52, the hot water circulation tank 54, the heating water tank 32, and the hot water tank 22 are provided with air discharging portions, respectively. The air discharge unit functions to discharge steam generated due to the temperature rise of hot water or heating water freely. At this time, a one-way valve for preventing foreign matter or water from flowing from the outside may be installed in the air discharge part.

The hot water preheating tank 52 is provided with a hot water supply valve 80 for allowing hot water of the hot water circulation tank 54 to flow into the hot water preheating tank 52 when the water level is lowered. The hot water supply valve 80 includes a plug member 84 disposed inside the heating water preheating tank 52 to open and close the opening hole 82 formed in the upper region of the heating water preheating tank 52, The stopper member 84 is provided inside the mesh case 86 provided at the upper part of the preheating tank 52 and is lifted or lowered according to the water level change of the heating water preheating tank 52 to open the opening hole 82 And a heating accommodating buoyancy body (88) that operates to close the heating body.

On the other hand, a branch pipe 54A is provided at the bottom of the hot water circulation tank 54. [ One end of the branch pipe 54A is connected to the circulation tank 54 and the other end is connected to the water pipe 54C installed in the shower or sink and the other end is connected to the three- . Therefore, when the water conductors 54C are closed, the hot water is circulated to the hot water tank 22 through the three-way connection pipe 22C.

In addition, a pipe connecting the lid warm water tank and the hot water circulation tank 54 is provided with a one-way valve for preventing hot water from flowing backward (again, not to enter the lid warm water tank), and a one- have.

The operation of the prefabricated boiler according to the present invention will now be described.

In the present embodiment, the use of briquettes as a fuel is described as a basis, but not limited thereto, and it is a matter of course that fissure or liquid fuel can be used as the fuel.

First, the lid hot water tank 24 is opened, the lid is removed, and then the ignited briquettes are put into the stove part 10, or the briquette is put into the ignition part.

At this time, the auxiliary tank 60 and the three-way connection pipe 22C are connected, the hot water circulation tank 54 and the three-way connection pipe 22C are connected, and the hot water outlet 22D and the lid warm water tank 24 And the lid warm water tank 24 is connected to the hot water circulation tank 54. Then, the heating water preheating tank 52 and the heating water inlet port 32A of the heating water tank 32 are heated.

In this state, when heat is generated in the hearth section 10, the water contained in the hot water tank 22 and the lid warm water tank 24 is heated to become hot water.

First, the hot water heated in the hot water tank 22 flows into the hot water tank 24 and is then heated again. Then, it circulates to the hot water circulation tank 54. The hot water contained in the hot water circulation tank 54 is discharged to the water conduction 54C through the branch pipe 54A when the water conduction 54C is opened and is discharged when the water conduction 54C is closed, And circulates to the hot water tank 22 through the hot water tank 22C.

Therefore, the user can use hot water through the water inlet 54C.

The hot water heated in the hot water tank 22 and the lid hot water tank 24 is heated by the heating water preheating tank 52 to preheat the heated water and discharged to the water tank 54C or used again in the hot water tank 22 ).

At this time, if the water level of the hot water is lowered, the water supply valve 64 of the auxiliary tank 60 is activated, and water can be replenished by opening the water pipe 62.

On the other hand, in the heating water preheating tank 52 of the communication preheating section 50, the hot water passing through the communication pipe 40 and the heating water preheated by the hot water circulation tank 54 are supplied to the heating water inlet port 32A, And the heating water that has been heated in the heating water tank 32 is circulated through the heating pipe 70 by the heating water circulation pump 32D.

As a result, heating of the heating space can be performed by the heating pipe 70 disposed in the heating space.

On the other hand, the heating water circulating through the heating pipe 70 flows into the heating water preheating tank 52 again.

When the water level of the heating water accommodated in the heating water preheating tank 52 is lowered, the heating receiving buoyancy body 88 is lowered. As a result, the stopper member 84 opens the opening hole 82, The hot water of the hot water circulation tank 54 which has already been heated to a predetermined temperature flows into the heating water preheating tank 52.

Accordingly, since the already heated water is introduced into the heating water preheating tank 52, the temperature of the heating water can be kept at a constant temperature without falling down.

Since the hot water is heated in the hot water tank 22 and the lid hot water tank 24 and then flows into the hot water circulation tank 54 and the hot water preheating tank covers the communication pipe 40, .

Also, since the hot water heating unit 20 and the heating water heating unit 30 surround the stove unit 10, the heat loss of the stove unit 10 can be prevented.

In the above-described prefabricated boiler, since the stove part 10, the hot water heating part 20 and the heating water heating part 30 serve as a stove, it is installed in the room to heat the room, It can be heated.

Figure 5 of the accompanying drawings shows another embodiment of the present invention.
