The present invention relates to a warm air heater, in particular, in a heat exchange type heating device of a warm air heater that can be used for heating by blowing heat from gas combustion, to improve the thermal efficiency and to control the humidity of the room appropriately to provide a comfortable heating. It relates to a heat exchanger of a hot air heater.

The hot air heater used in the related art was a method of directly heating the outside air to the outside of the burner combustion chamber to directly deliver it to the room.

However, this method uses only directly heated air as a warm air, and its thermal efficiency is very low, which consumes a lot of energy. In addition, when the air is dried and muddy for a long time, the indoor user may experience various diseases and headaches. What caused the problem was that it caused the health of the human body.

In addition, in Japan, a hot air heater that slightly improves this conventional problem was disclosed in 1984 (No. 59-94216), but a combustion unit and a heat exchanger are respectively disposed in the main body, and the air supply pipe is opened by driving a combustion fan. The outdoor air in the hot air heater for guiding outdoor air to the combustion unit to combust fuel in the combustion unit and inducing combustion gas generated in the combustion unit to the outside through an exhaust pipe connected to the thermally effective pipe and the thermally effective ventilator. The invention is characterized in that the outdoor air supply passage for forming a fresh air supply pipe and an exhaust pipe for introducing the inside of the indoor air distribution passage in the main body, a triple supply and exhaust pipe having a fresh air supply passage and an exhaust passage are installed. The main focus was on improving the exhaust pipe, but again the heat exchanger was in communication with the combustion chamber. The arrangement of a plurality of pipes and the combustion gas passes through the pipe to increase the pipe surface temperature, and then heats the outside air with the heat of the combustion chamber and the pipe surface and sends it to the room. Therefore, the thermal efficiency of the heat ventilation is not greatly improved. Of course, there was also a problem that the air coming into the lower part of the hot air heater is heated in the combustion chamber and the thermal effect pipe and directly delivered to the upper part of the hot air fan to the indoor air to dry and muddy the indoor air to finish the bad effect on the human body when used for a long time.

The present invention has been devised to solve the above problems and described in detail by the accompanying drawings as follows.

The present invention is connected to the connection port (8) through the inlet pipe (7) to the suction pipe (6a) of the main body (1) back intake and exhaust pipe (6) to the fan (9) through the transfer pipe (10) to the combustion chamber (5) The forced air is drawn in and supplied to the combustion air, and after combustion, the exhaust gas is discharged to the exhaust pipe 6b installed and positioned at the center of the intake and exhaust pipe through the discharge pipe 13 and the discharge pipe 13a, It is configured to let the outside air forced into the main body (1) through the burner (4) to the outside of the combustion chamber (5) heated by the burner (4) to the room through the hot air outlet (4 ') of the lower front of the main body (1) In the warm air heater, the combustion gas that is forcedly drawn into the combustion chamber 5 through the transfer plate 10 by the fan 9 and enters the heat exchanger 12 through the connection pipe 11 enters the air resistance part 12a. The flow is delayed by sending the discharge pipe 13a by slowly circulating the inside of the heat exchanger 12 along the transfer path 12 '. The outside air supplied to the blower fan 3 deodorizes water vapor when it is heated and passed through the combustion chamber 5 and the heat exchanger 12 when the hot air hits and is reflected by the water stored in the water tank 14. In the drawing, reference numeral 15 in the drawing is a diaphragm that regulates the pressure difference between the connector 8 and the transfer pipe 10, and 16 is to control the power of the fan 9 to control the power. A switch attached to the diaphragm 15, 17 indicates a pressure tube.

Next, the operating state of the present invention will be described.

As such, the present invention mainly fixes the main body 1 to the wall surface W, and the intake and exhaust pipe 6 is installed in such a manner as to expose the outside by penetrating the wall so that the combustion gas is discharged to the outside without spreading to the room even if used for a long time. When the gas is burned by the burner 4 at the same time as the power supply is connected, high heat is generated in the combustion chamber 5 by the heat of combustion. Oxygen required for combustion is taken from the suction pipe 6a in the intake and exhaust pipe 6 exposed to the outside of the wall surface. ) Can be supplied by drawing outside air.

This air is guided to the inlet pipe 7 and the connector 8 so as to continuously supply oxygen necessary for combustion to the lower part of the combustion chamber 5 through the transfer pipe 10 by the forced air of the fan 9.

4 shows a schematic operating state of the present invention.

After forced air blowing, the air introduced into the main body 1 becomes hot and is discharged from the combustion chamber 5 to the connecting pipe 11 and drawn into the upper part of the two heat exchangers 12 in communication with the connecting pipe 11. The flow is suddenly delayed by the air resistance 12a, and the two heat exchangers 12 are slowly circulated along the transfer path 12 '.

Thereafter, the exhaust pipe 13a and the discharge pipe 13 connected to the upper portion of the rear surface of the heat exchanger 12 on one side of the exhaust pipe 6b formed at the center of the intake and exhaust pipe 6 are discharged from the end to the outside. Repeat.

When the heated exhaust gas circulates through the heat exchanger 12, when the outside air is transferred to the lower side by the blower fan 3, the outside air is heated and the exhaust gas gradually cools.

In addition, when discharged to the exhaust pipe (6b) is installed on the outside to provide a kind of heat exchange action to preheat to some extent the outside air drawn into the inlet pipe (7) to supply oxygen to improve the efficiency of combustion in the burner (4) It is possible.

Next, a humid hot air is demonstrated.

The outside air forced into the center of the main body 1 by the blower fan 3 passes through the combustion chamber 5 and the heat exchanger 12, and then hits the water of the water tank 14 located directly under the heated state. As the water continues to heat up and rises to an appropriate temperature, water vapor is generated. Therefore, when reflected from the foreign material, the heat deodorizes the water and heat and steam together through the hot air outlet (4 ') under the main body (1). It will be supplied indoors.

By repeating this process, heated air and water vapor are supplied to the room to heat the room warmly and at the same time, it can continuously supply the moisture necessary for the human body with heat, thus eliminating the phenomenon of drying in the room even if it is heated for a long time. It is possible to avoid feeling of discomfort or headache at all, and exhaust gas is discharged to the outside, and after introducing the outside air and burning it, it is possible to prevent the lack of oxygen in the room.

When the pressure of the air required for the combustion chamber 5 is unnecessarily high by connecting the pressure tube 17 to both sides of the diaphragm 15 at the connector 8 and the transfer pipe 10, the pressure is transferred to the transfer pipe 10. Since the pressure tube 17 interrupts the diaphragm 15 to short-circuit the switch 16, the power supply connected to the fan 9 can be cut off to suspend supply of external air necessary for combustion. When the pressure of the 10 is high, the switch 16 is contacted to drive the fan 9 to automatically draw in the outside air.

The present invention, as described above, by supplying the heat and steam passing through the heat exchanger 12 through which the combustion heat and exhaust gas circulated at the same time to obtain a very high thermal efficiency economical to maintain the humidity required for the human body at all times It is a useful design.
