Reference numeral 19 in the drawings denotes a pedestal for supporting a container containing water when the water or the like is boiled through the stove to the upper part of the stove main body.

Thus, in the stove configured as described above, the fuel such as wood put on the grate 14 is burned by burning, so that the heating operation of the indoor space is performed through the radiant heat transmitted from the stove body 10 to the indoor space through the combustion heat generated at this time .

On the other hand, an air warming pipe 40 is provided in the stove main body 10 as a constitution for warming and circulating the indoor air around the stove main body 10 by using the heat of the combustion chamber 10a.

3, the air warming pipe 40 is provided in the form of a hollow tube having open ends at both ends thereof, so that both ends of the air warming pipe 40 communicate with the outside of the stove body 10 through the combustion chamber 10a, So as to have a height. The air warming pipe 40 may be integrally fixed to the stove body 10 through a welding method.

Therefore, when the air warming tube 40 is installed in the hearth body, the air warming tube 40 is heated by the heat inside the combustion chamber 10a, and the air warmed in the air warming tube 40 is heated And the indoor air introduced into the air warming pipe 40 is heated again through the other end of the air warming pipe 40 to be heated again through the one end of the pipe 40, The indoor air of the indoor unit can circulate along the air warming pipe 40 and can be heated as a whole.

In the stove structure in which the indoor air around the stove is heated by the radiant heat radiated from the stove body 10 and circulated along the air warming pipe 40, the indoor space around the stove is heated evenly in a shorter time Therefore, the heating efficiency of the room can be effectively improved even if only a small amount of fuel is used.

One end located at the lower end of the air warming pipe 40 is an inlet 41a for guiding the inflow of indoor air and the other end of the air warming pipe 40 positioned higher than the inlet 41a is connected to an air warming pipe 40 and the outlet 42a for discharging the warmed air back into the indoor space.

As shown in FIG. 4, the flow of the indoor air circulating along the air warming pipe 40 can be formed more naturally, and at the same time, the air warming pipe (not shown) is installed so that the heated indoor air can be evenly distributed to every corner of the indoor space The inlet 41a and the outlet 42a of the combustion chamber 10 are disposed on both sides of the furnace body 10 in the diagonal direction so that the inlet 41a and the outlet 42a of the combustion chamber 10 are located at the lower side and the upper side of the combustion chamber 10a, respectively.

 The air warming pipe 40 installed to penetrate the combustion chamber 10a and occupying a part of the internal space of the combustion chamber 10a is preferably installed so as not to hinder the combustion operation of the fuel. The air warming pipe 40 prevents the fuel from being injected into the combustion chamber 10a through the fuel inlet 12 and prevents the surrounding of the combustion chamber 10a from being blocked around the grate 14, It is preferable to be provided so as to be close to the inner surface. It is preferable that the air warming pipe 40 located at the combustion chamber 10a is disposed between the opposite ends of the combustion chamber 10a so as to be adjacent to at least the inner surface of the combustion chamber 10a rather than the center of the combustion chamber 10a, Is disposed inside the combustion chamber 10a such that the distance between the air-warming pipe 40 and the air-warming pipe 40 is smaller than the thickness of the air-

In the present embodiment, the air warming pipe 40 is provided in the shape of a pipe and has an air inlet 41 at one end, an air outlet 42 at the other end, And has a central connecting portion 43 formed to be elongated for connection. A safety grill net 40a for preventing a safety accident may be installed at the inlet 41a and the outlet 42a of the air heating pipe 40 exposed to the outside of the stove main body 10a.

The inlet 41a and the outlet 42a of the air warming pipe 40 are formed through the ends of the air inlet 41 and the air outlet 42 respectively and the connecting portion 43 is bent in a ' . The air inlet portion 41 and the air outlet portion 42 guide the air discharged into the air heating pipe 40 or heated while being heated through the air heating pipe 40 in the diagonal direction of the stove main body 10 And the connecting portion 43 is bent at both ends in a diagonal direction.

The air warming pipe 40 passing through the combustion chamber 10a in such a manner that the combustion chamber 10a is bent so as to be adjacent to the inner surface of the combustion chamber 10a without passing through the combustion chamber 10a linearly has a problem that the space utilization of the combustion chamber 10a is lowered The indoor air can be sufficiently heated by making it possible to sufficiently receive the heat of the combustion chamber 10a while the room air passes through the air warming pipe 40. [

The air warming pipe (40) may be composed of a plurality of air warming pipes (40) so that indoor air can be warmed while circulating more quickly. In this embodiment, the air warming tubes 40 are provided in a pair, and a pair of the air heating tubes 40 are arranged such that the directions of the fluids flowing along the respective air heating tubes 40 are opposite to each other, The inlet 41a and the outlet 42a of the warming tube 40 are connected to the inlet 41a and the outlet 42a of the other air heating tube 40 in the opposite direction with respect to the center vertical axis of the combustion chamber May be provided

Unlike the present embodiment, the air warming pipe 40 can be constituted by a plurality of three or more. The plurality of air warming pipes 40 are connected to the grate 14 in consideration of the moving direction of the internal heat of the combustion chamber 10a moving from the grate 14 to the communication port 20a so as to uniformly receive the heat inside the combustion chamber 10a. A plurality of air warming pipes 40 may be installed in the stove main body 10 between the upper part and the communication part 20 in order to circulate indoor air more evenly, (41a) and the outlet (42a) of the other air warming pipe (40) are arranged in mutually opposite directions about the center vertical axis of the combustion chamber and the inlet (41a) and the outlet (42a) The direction of the fluid guiding pipes 40 may be opposite to each other. 5 shows the cross-sectional structure of the hearth, and shows the structure viewed from the bottom to the top of the combustion chamber 10a.

In addition, in the structure in which the heat inside the combustion chamber 10a is directly discharged to the communication pipe 20 together with the combustion gas, there is a limit in effectively heating the air warming pipe 40 using the heat inside the combustion chamber 10a, A connection hole 16 is formed in the combustion chamber 10a so as to allow communication between the combustion chamber 10a and the communication port 20 in the connection hole 16 to which the communication port 20 is connected, A heat discharge retarding plate 50 may be provided which is spaced apart.

The heat of the combustion chamber 10a is discharged to the outside of the combustion chamber 10a through the communication 20 while bypassing the heat release retardation plate 50. Therefore, It is possible to delay the stay of the inside of the combustion chamber 10a for a long time, and the heating efficiency of the air warming pipe 40 due to the heat of the combustion chamber 10a can be further improved.

In the case of the air warming pipe 40 as a whole, it can be constituted by the same iron plate as the stove body 10. However, in consideration of the heating efficiency of the air heating pipe 40 by the heat dissipation of the heat dissipating chamber 10a, It is preferable to be made of a material having a high thermal conductivity such as copper. However, since the price of copper is much higher than that of a general steel plate, if the air heating pipe 40 is formed entirely of copper, the overall manufacturing cost of the furnace may increase.

Therefore, in the present embodiment, the air warming tube 40 is formed of copper or copper alloy only in a part of the plate surface 43a in a region located inside the combustion chamber 10a, and the remaining plate surfaces of the air warming tube 40 The heating efficiency of the air warming pipe 40 can be increased while suppressing a large increase in the unit price of the air warming pipe 40 composed of the iron plate.

The heating efficiency of the air warming tube 40 due to the combustion of the combustion chamber 10a can be improved by making the plate surface, which is most likely to receive the heat of the combustion chamber 10a, be made of copper or a copper alloy, The air warming pipe 40 of the present embodiment is provided with a plate surface 43a facing the inside of the combustion chamber 10a in the connection portion 43 through copper or a copper alloy.

Accordingly, when the fuel is burned in the combustion chamber 10a in the structure of the stove configured as described above, the room air around the stove is heated by the radiant heat radiated from the stove body 10, and while being circulated along the air warming pipe 40, So that the indoor space in which the stove is installed can be evenly heated in a short period of time.

6, a pair of air warming tubes 40, which are arranged such that the inlet 41a and the outlet 42a are opposite to each other, inflow indoor air to both sides of the furnace body 10 So that the indoor air is circulated more quickly and the heating rate of the indoor air is increased. The solid arrows in FIG. 6 represent the flow of room air circulating through the air heating pipe 40.

As shown in FIG. 7, the air warming pipe 40 'is inserted into the combustion chamber 10a in such a manner that both ends of the air warming pipe 40' are tightly coupled to the inner surface of the combustion chamber 10a Can be installed in the furnace body 10 '. At this time, the air heating pipe 40 'inside the combustion chamber 10a can be welded to the inner surface of the combustion chamber 10a through the outer peripheral surface, and the plate surface 43a made of copper and copper alloy in the air heating pipe 40' May be configured through the opposite surface of the surface coupled to the inner surface of the combustion chamber 10a.

In addition, the air warming pipes 40 and 40 'are connected to the outside of the combustion chamber 10a through both ends thereof, and the inside of the combustion chamber 10a at least a part of the outer surface between the both ends is located within the combustion chamber 10a' . ≪ / RTI >

The air warming pipe 40 ', which is closely attached to the inner surface of the combustion chamber, is spaced away from the inner surface of the combustion chamber 10a. The space utilization of the combustion chamber 10a due to the installation of the air warming pipe 40 'can be further improved while maintaining the size of the heater body 10' and the air heating pipe 40 ' do.

In the case of this embodiment, the overall structure of the stove except for the installation of the air warming pipe 40 'and the heating improvement effect according to the air warming pipe 40' are the same as those of the first embodiment described above, Omit it.
