The present invention accelerates the heating of the double combustion plate by removing the unburned gas generated during the circuit ignition of the fan heater into the combustion chamber and reintroduces it into the combustion chamber. The present invention relates to a device for removing unburned gas during ignition of a fan heater, which is intended to supply purified hot air at all times by operating the engine.

In general, since the combustion chamber and the double-combustion plate composed of the fan heater are not preheated during the initial ignition, the incompletely burned gas after the initial ignition is released into the room as it is, which not only produces a bad smell but also causes a human respiratory disease. There are various problems.

The present invention is intended to solve such a conventional problem, the "c" type guide tube for the unburned gas generated during initial ignition by disposing a "c" type guide tube configured with an inlet and an exhaust port on one side of the duct configured inside the heater body. By circulating the oil inlet into the combustion chamber, it is possible not only to preheat the combustor but also to prevent the emission of harmful gases harmful to the human body to the room, and to shorten the complete combustion time of the gas by preheating the combustor. At the same time as to warm up and expected to reduce the fuel effect according to this invention devised as described in detail by the accompanying drawings as follows.

In the center of the heater body 1, the burner 3 is adhered to the fixing stand 2, and the combustion chamber 5 and the double burner plate 6 interlocked with the burner 3 are formed in the upper duct 4. In this case, the duct 4 is coupled to one side of the "c" type guide tube (7), but the intake port (9) in which the upper suction fan (8) is built up to be interlocked with the duct (4) and the lower exhaust port (10) The interlock valve 14 is interlocked with the combustion chamber 5 so as to form a reverse displacement 14 coupled to the pin 13 in the central hole 12 of the assembly 11 inserted into the one end of the exhaust port 10.

Reference numeral 15 denotes an air inlet, and 16 denotes a convection fan.

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

The combustion gas generated at the first ignition is not in a state in which the combustion chamber 5 and the double combustion tube 6 are not heated, so that complete combustion of the gas is not performed.

At this time, the operation of the convection fan 16 is stopped and the suction fan 8 is operated so that the incomplete combustion gas that rises is sucked by the suction fan 8 and the suction port 9 of the upper portion of the "C" guide tube 7 is provided. ) Is sucked into the bottom exhaust port 10 and re-introduced into the combustion chamber 5.

Therefore, since the incomplete combustor continuously generated is in the state in which the convection fan 16 is in a stopped state, it is controlled to be discharged into the room and is inside the heater body 1 along the “c” type guide tube 7 by the suction fan 8. Iterate over and over again.

At this time, the incomplete combustion gas flowing back into the combustion chamber (5) also has a significant amount of heat, and thus has the heating of the combustion chamber (5) and the double combustion tube (6), which causes the heating of the combustion chamber (5) and the double combustion tube (6) to be suspended. By shortening the complete combustion time of the gas, it is possible to remove the purified hot air discharge in the room, and thus, it is possible to expect a fuel saving effect, and a reverse displacement (14) installed at the exhaust port 10 at the bottom of the "c" guide tube (7). Incomplete combustion gas that is sucked in is opened when the gas is re-introduced into the combustion chamber 5, and the combustion gas inside the combustion chamber 5 is prevented from flowing back. Therefore, the incomplete combustion gas through the "c" guide tube 7 The circulation is made easy without difficulty.

When the combustion chamber 5 is heated while the circulation process is repeated, the gas is completely burned, so the suction fan 8 of the "c" guide plate 7 is stopped and the convection fan 16 is operated, so that smoke is not generated in the room. Only the purified air is released at all.

As such, the present invention prevents the emission of odor or smoke in the room by circulating the incomplete combustion gas generated during the initial ignition of the heater as it is in the room without releasing it as it is, and the combustion chamber and the double combustion pipe by the incomplete combustion gas circulated. Heating is accelerated further, which can shorten the complete time of the gas, which is a useful design that can be expected to save fuel.
