The present invention is used for the purpose (heat exchange) from the combustion furnace and the combustion furnace assembly in the warm air heater, and the combustion gas is discharged to the outside through the flue, by recovering and utilizing the residual heat of the discharged combustion gas for the humidifier or The present invention relates to a warm air heater capable of selectively performing an effective heat exchange function.

In the conventional case, a hot air heater is heated in a combustion furnace and a combustion furnace assembly when a normal combustion process in which combustion air is mixed with fuel and combusted in a combustion burner is performed, wherein the sucked indoor air is a combustion furnace and combustion. Although it was discharged into the room while being heat-exchanged with the furnace assembly, it was used according to the purpose of indoor heating.

Therefore, the present invention recovers the above-mentioned drawbacks by using the residual heat in the waste gas discharged from a typical warm air heater, and is designed to perform a humidification function and an efficient heat exchange function selectively. The configuration and the operation and effect will be described in detail with reference to the drawings.

Combustion air is sucked in the structure of the warm air heater (1) and mixed with fuel to perform a normal combustion process by the combustion burner (2), and a combustion furnace (3) and a combustion furnace assembly (connected to the combustion burner (2)). The heat exchanger plate 5a in which several legs 50 of different lengths are integrally formed on the combustion furnace assembly 4 in heat exchanged indoor air that is sucked by the combustion gas discharged 4). And a humidifier 5, which is a humidification means composed of a bucket 5b and an outer body 5c, and a heat exchange pipe 6, which is a heat exchange means, are selectively installed as necessary to utilize residual heat in the discharged combustion gas. The connection structure of the furnace assembly 4 and the humidifier 5 or the heat exchange pipe 6 is such that the protrusions 4a of the furnace assembly 4 and the protrusions 5d or heat exchanger of the humidifier 5 are constructed. When assembling detachably, the inner surface of the fixture 7 is caught by the protrusion 6a of the pipe 6 That is configured to facilitate exploded Reference numeral 8 is a supply pipe, an exhaust pipe 9, 10 is a convection fan, 11 inlet, 12 discharge port, 13 is a T-shaped connection tube, 1a is a cabinet.

Referring to the effect of the present invention configured as described above is as follows.

As described above, the present invention has a structure in which a user can selectively connect and assemble a humidification means and a heat exchange means on the combustion furnace assembly 4 of the hot air heater 1 having a normal heating function according to the user's needs. In order to simultaneously perform a typical hot air heating function and a humidification function with one hot air heater 1, the upper part of the combustion furnace assembly 4 of the hot air heater 1 is shown in FIGS. 1 and 2. When the humidifier (5), which is a humidification means, is detachably connected to the fixture (7) to operate the warm air heater (1), the outdoor air (combustion air) is sucked through the supply pipe (8), and fuel supplied from an arbitrary source. The combustion furnace 3 and the combustion furnace assembly 4 connected to the combustion burner 2 in communication with the combustion burner 2 as the combustion progresses in the combustion burner 2 (normal combustion process) are carried out outdoors through the exhaust pipe 9. To combustion gas (waste gas) The air is sequentially heated, and at the same time, the indoor air sucked through the inlet port 11 by the rotational force of the convection blower 10 is in contact with the surface of the heated combustion furnace 3 and is primarily heat-exchanged. In contact with the furnace assembly 4 again, the second heat exchanger is discharged into the room through the discharge port 12 above the cabinet 1a to heat the indoor air, while the combustion furnace 3 and the furnace assembly 4 are heated. The remaining heat in the combustion gas that is heated and discharged to the outside is transferred to the outer body 5c of the humidifier 5 by the heat transfer plate 5a by heating the heat transfer plate 5a through the legs 50 and the water tank 5b. It is possible to perform a humidification function simultaneously with the heating function, by allowing the water supplied from the evaporation to the room to moisten the dry indoor air during heating, wherein the furnace assembly (4) and the humidifier (5) have their respective protrusions. The inner part of the fixture 7 to (4a) (5a) is as shown in FIG. 3 Since it is firmly caught, it will not break away.

In addition, when the humidification function is not required, as shown in FIG. 4, the heat exchange pipe 6, which is a heat exchange means, is fixed to the upper part of the combustion furnace assembly 4 of the warm air heater 1 as shown in FIG. When the hot air heater 1 is operated after assembling, the high temperature combustion gas from which the combustion furnace assembly 4 connected to the combustion burner 2 is discharged to the outdoors by the above-described conventional combustion process. It is heated by the heat exchange pipe 6 is connected to the fixture (7) through the cabinet (1a) to the upper part of the furnace assembly (4) while the T-shaped connecting pipe (13) side of the furnace assembly (4) Since some of the high-temperature waste gas discharged from the furnace assembly 4 to the outside is heated with the heat exchange pipe 6, the waste gas discharged from the furnace assembly 4 through the T-shaped connecting pipe 13 and Together it is discharged to the outdoors.

Therefore, the indoor air sucked into the cabinet 1a is primarily heat exchanged with the outer surface of the combustion furnace 3, the secondary heat exchange is performed in the furnace assembly 4, and the third heat exchange is performed at the outer surface of the heat exchange pipe 6. Increasing the rate can improve the heating efficiency.

As described above, the present invention, in the hot air heater (1) having a normal combustion process, the humidifier (5) or the heat exchange pipe (6) selectively mounted on the combustion assembly (4) according to the user's needs. Easily detachable and firmly fixed, it is possible to solve various vulnerabilities such as lowering heat exchange and high temperature waste gas discharge, which are the causes of defects in conventional hot air heaters, that is, high temperature discharged from hot air heaters (1). As the heat remaining in the waste gas can be recovered and recycled, it will have a great effect on energy saving.
