らに高められたときに開となる。When the operation switch (41) is turned on, the control circuit (40)
First, close the relay switch (42) and evaporate the heater (20).
To increase the temperature of the burner body (21) of the burner (10). When the burner body temperature becomes equal to or higher than the predetermined temperature, the relay switch (43) is closed, and the air supply fan (27) is rotated by energization of the combustion motor (34), so that the room air is supplied to the combustion air inlet (4) and The air is supplied to the burner (10) through the air supply passage (11) to perform pre-purge. When a predetermined time elapses after the relay switch (43) is closed, the relay switch (44) is closed and the convection motor (14) is energized, and the convection fan (15) rotates to draw indoor air into the indoor air intake (14). It is introduced into the hot air passage (12) through 3). In addition, the relay switch (45) enters the normally open (NO) contact to energize the ignition device (25), and the electromagnetic pump (19)
Is also energized. For this reason, kerosene is supplied from the oil reservoir tank (17) to the burner (10), and is ignited by a mixed gas of the vaporized gas and the combustion air, and combustion starts. Then, the indoor air introduced into the hot air device (12) hits the combustion tube (9) and is heated, mixed with the exhaust gas of the burner (10), and discharged from the hot air outlet (2) into the room. You. During combustion, the relay switch (46) opens and the solenoid valve (33) is not energized, so that the valve body (31) of the damper device (26) opens (2
8) Close and open the opening (30). The relay switch (42) is opened when the temperature of the burner body (21) is further increased by heat conduction from the burner head (24) to the burner body (21).

点滅する。When the operation switch (41) is opened, the control circuit (40) stops the combustion as follows. First, the control circuit (40) switches the relay switch (45) to the normally closed (NC) contact, immediately discharges the charge of the capacitor (53) via the resistor (52), and stops the electromagnetic pump (19). Extinguish. Further, the relay switch (43) is opened to stop the combustion motor (34), the relay switch (46) is closed, and the solenoid valve (33) is energized. Therefore, the valve element (31) of the damper device (26) closes the opening (30) and opens the opening (28) as shown by a broken line in FIG. Further, since the air supply fan (27) stops immediately (in 1 to 2 seconds) and the convection fan (15) continues to operate, the air pressure in the hot air passage (12) increases inside the burner (10) and the air supply. It becomes higher than the pressure in the passage (11). The unburned gas in the vaporization chamber (22) is not supplied to the burner head (24), but is supplied to the supply passage (11) and the opening (28).
And is collected in the space of the oil sump tank (17) through the communication pipe (36), where it is cooled and liquefied. When the required time (for example, 5 minutes) elapses after the operation switch (41) is opened and the collection of the unburned gas ends, the relay switch (44),
(46) is opened, the convection motor (14) is stopped, and the energization of the solenoid valve (33) is stopped. In this way, the unburned gas inside the burner (10) can be collected in the oil sump tank (17) during the fire extinguishing operation without being discharged into the room together with the warm air, thereby preventing odors from being emitted into the room. it can. In addition, the indicator lamp (55) is turned on or blinks during the collection of the unburned gas.

できる(第7図参照)。That is, as shown in FIG. 5, first, it is determined whether or not the unburned gas is being collected, and if five minutes have not elapsed since the operation switch (41) was opened (extinguished), the next step is performed. Next, it is determined whether or not the detected temperature T (room temperature) of the room temperature sensor (54) is equal to or higher than a predetermined temperature T S (for example, 5 ° C.). And
When the room temperature T is equal to or higher than T S, the unburned gas is collected
When the display lamp (55) is continuously lit or blinking and the recovery of the unburned gas is completed, combustion operations such as preheating, pre-purge, and ignition of the burner body (21) are sequentially performed (see FIG. 6). Therefore, at the start of combustion, most of the unburned gas is collected in the oil reservoir tank (17), and there is no fear that a bad smell is emitted into the room. In addition, when the display lamp (55) is turned on or blinks, the customer can know that the unburned gas is being collected (smell removal). On the other hand, when the room temperature T is lower than T S , the operation switch (41) is turned on,
Since the recovery of unburned gas is stopped and the operation shifts to combustion operation,
The combustion operation is immediately restarted, and the room temperature can be raised (see FIG. 7).
