1 and 3, the boiler 1 according to the present embodiment includes a storage tank 10, a first heating unit 20, and a second heating unit 30.

The storage tank 10 includes an outer tank 10a and an inner tank 10b. The inner tank 10b is positioned at intervals inside the outer tank 10a. The spacer (not shown) which maintains a space | interval is located between the outer tank 10a and the inner tank 10b.

The space 10d between the outer tank 10a and the inner tank 10b is filled with a heat medium such as oil. The heat medium of the interspace 10d is filled in a vacuum state. The heat medium may exchange heat with the second heating unit 30. On the other hand, a heater (not shown) for heating the heat medium may be provided in the interspace 10d.

Inside the inner tank 10b, a storage space 10c in which heating fluid such as water is stored is formed, and a circulation pipe 14 is mounted outside. And supply pipe (not shown) which can supply a heating fluid in the case of lack of heating fluid is provided.

The circulation pipe 14 is coupled to the upper portion of the storage tank 10 on the other side of the lower portion of the storage tank 10 in the state installed in the heating area. The circulation pipe 14 is equipped with a circulation pump 141.

By the pumping of the circulation pump 141, the fluid stored in the storage space 10c may automatically flow into the circulation pipe 14, and then flow back into the storage tank 10 after circulation of the heating area. The circulation pipe 14 is equipped with an on-off valve 142 may allow the user to control the flow of the heating fluid.

The outer side of the storage tank 10 may be provided with a tube 13 of a transparent material that allows the user to visually check the capacity of the heating fluid. However, at least a portion of the storage tank 10 may be formed as a transparent window along the longitudinal direction.

The storage tank 10 is provided with an air vent 11 for discharging air generated while the heating fluid circulates, and a thermometer 12 for sensing the temperature of the heating fluid.

The peripheral surface of the storage tank 10 may be provided with a heat insulator (not shown) for preventing external heat from being transferred to the storage space 10c or from transferring the heat of the storage space 10c to the outside.

An upper surface of the storage tank 10 may be opened, and a cover (not shown) is detachably installed at the open portion. By removing the cover, it is easy to maintain the components installed in and inside the storage tank 10.

In order to protect the storage tank 10 from external shocks and vibrations, the storage tank 10 is installed on the pedestal 15. Pedestal 15 is firmly fixed to the ground, such as anchor bolts.

The first heating unit 20 heats the heating fluid stored in the storage space 10c. The heated heating fluid can heat the heat medium while exchanging heat with the heat medium filled in the interspace 10d. The first heating unit 20 may be a burner using an electrically connected heater or gas or oil.

When the first heating unit 20 is a heater, a group consisting of a coil heater, a dryer heater, a quartz tube heater, a far infrared heater, a plating heater, an input heater, a sheath heater, a fin heater, a casting heater, a cartridge heater, and a combination thereof Any one selected from may be applied.

The first heating unit 20 may be made in various ways and is not limited to a heater and a burner.

The second heating unit 30 is located in the storage space 10c and is heated while being heat-exchanged with the heating fluid heated by the first heating unit 20. The second heating part 30 includes a support part 31 and a heat medium storage part 32.

The support part 31 is formed in at least one bar shape, and both ends are fixed to the inner circumferential surface of the storage tank 10. The support part 31 may have a plurality of mounting holes 311 formed at intervals so that the heat medium storage part 32 may be mounted at intervals.

The heat medium storage part 32 includes a storage body 321 and a mounting member 322 in which the heat medium is accommodated.

Referring to FIG. 4, a heat medium made of oil is accommodated in the storage body 321. At this time, the heat medium is accommodated in a vacuum state, it can be heated while heat exchange with the heated heating fluid.

One side of the storage body 321 is open, the open portion may be provided with a stopper (not shown). A packing is installed between the stopper and the storage body 321 to prevent leakage of the heat medium. The heat medium may be exchanged or the interior of the storage body 321 may be inspected with the cap open.

On the other hand, if the storage body 321 is made of a plurality may be connected to each other and the heat medium can circulate. In addition, a heater (not shown) for heating the heat medium is installed in the storage body 321 to directly heat the heat medium.

The mounting member 322 is formed at the other side of the storage body 321 and is coupled to the mounting hole 311. The mounting member 322 may be a bolt. Accordingly, when the nut is fastened while the bolt penetrates through the mounting hole 311, the storage body 321 may be firmly fixed to the support part 31. The structure for coupling the storage body 321 to the support 31 may be fixed in various structures in addition to the bolt nut.

On the other hand, the outside of the storage tank 10 is equipped with a control unit 40 that is electrically connected to the first heating unit 20, the circulation pump 141 and controls.

Next, the operation of the boiler described above will be described.

In order to raise the temperature of the heating area in which the circulation pipe 14 is installed, the first heating unit 20 and the circulation pump 141 are operated through the control unit 40.

The temperature is increased while the heating fluid of the storage space 10c is heated by the first heating unit 20. At this time, the heating fluid of which the temperature rises is heat-exchanged with the heat medium of the second heating part 30 and the heat medium filled in the interspace 10d. The heat medium maintains the same temperature as the heating fluid by heat exchange. The heated heating fluid may check its temperature outside the storage tank 10 through the thermometer 12. The heat medium can be directly heated by the heater. When the heat medium is heated by the heater, it can be heated to a higher temperature than the fluid.

Meanwhile, the heated heating fluid circulates and heats the heating zone along the circulation pipe 14 by the operation of the circulation pump 141. The heating fluid circulated through the heating zone may flow back into the storage space 10c and be heated by the first heating unit 20 again. In this case, the user may adjust the flow of the heating fluid by using the on / off valve 142.

In addition, heating of the heating fluid can be efficiently performed by the second heating unit 30 and the first heating unit 20 heated by the heating fluid and the heat exchange, and since the second heating unit 30 is heated, 1 The heating fluid may be heated in a state where the heating unit 20 is stopped.

In addition, the heated second heating unit 30 may slow down the cooling rate of the heating fluid stored in the storage space 10c.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided.
