気に若人して燃焼を行なっている。(B) Conventional technology As disclosed in Japanese Unexamined Patent Publication No. 55-17087, this type of conventional combustor heats the burner body with a vaporization heater at the time of ignition, and detects the temperature when it reaches a predetermined temperature. When the burner motor detects this, it starts operating the burner motor to perform a bleed purge, and then activates the electromagnetic pump and igniter to inject the mixture of the vaporized gas and the combustion air supplied by the burner motor into a mixture that starts combustion. I am doing it.

る。However, the starting characteristics of the burner motor deteriorate as the temperature decreases, and the time required for the rotation speed to stabilize becomes longer. Therefore, if the bripurge time is fixed using a timer, the amount of fuel supplied and the amount of combustion air will be well balanced at room temperature, resulting in good ignition, but at low temperatures, the amount of fuel supplied will be There is a problem that ignition does not occur due to a small amount of combustion air (low rotational speed of the burner motor), or, in the case of an indoor open type combustor, a bad odor lingers even if ignition occurs.

20) is supplied with DC power. For this reason, the burner body (
6) is low, the resistance value of the burner thermistor (14) is large, the first comparator (22) outputs a high level, the transistor (27) is conductive, and the first relay (29)
) is excited. Then, the switch (29A) is closed and the vaporization heater (8) is energized to heat the burner body (6). The second comparator (30) outputs a low level because the burner thermistor (14) has a large resistance value, but the burner body (6) heated by the heater (8) is heated by the kerosene oil. When it reaches a temperature that allows it to vaporize, it reverses and outputs a high level. This results in transistor (35)
conducts, the second relay (36) is energized, its switch (36A> is closed, the burner motor (2) and the warm air blowing fan motor (21) start operating, perform blipurge, and open the vaporization chamber ( 7) Release any residual gas inside.

ものである。Further, the high level output of the second comparator (30) can be input to the blip-purge timer circuit (38), and the timer circuit (38)
After the delay time according to 8), the third comparator (40) outputs a high level, makes the transistor (47) conductive, energizes the third relay (48), and closes its switch (48A). It operates the spark plug (15) and electromagnetic pump (13). The delay time of the timer circuit 38> differs depending on the indoor temperature, that is, the resistance value of the room temperature detection thermistor (37), so the delay time becomes longer when the room temperature is low, and conversely becomes shorter when the room temperature is high. This was done in consideration of the fact that the lower the room temperature, the worse the starting characteristics of the burner motor (2), the longer it takes for the rotational speed to stabilize, and the smaller the amount of combustion air compared to the amount of fuel supplied.

0) outputs a high level, and as mentioned above, the transistor (4
7) is conductive, the third relay (48) is energized, and when the switch (48A) is opened, the igniter (15) and the electromagnetic pump (13) are activated, and the flame port (12) of the burner head (10) is activated. ) The mixture ratio of the vaporized kerosene gas ejected from the combustion air and the combustion air increases to a good mixture, and combustion begins.The ignition bladder (15) operates after the timer time of the built-in timer circuit. stop.

However, according to the present invention, the operating time of the burner motor is increased as the temperature decreases, so that the amount of fuel supplied and the amount of combustion air are kept at an appropriate level. The mixture ratio improves ignitability, and in the case of an indoor open type combustor, no bad odor wafts into the room.

路。(1) In an oil vaporization type combustor, kerosene supplied to the burner body by an electromagnetic pump is vaporized by a vaporization heater, mixed with combustion air supplied by a fan driven by a burner motor, and then ignited and burned by an ignition device. a circuit for detecting the temperature of the burner body; a circuit for starting operation of the burner motor when the detection circuit detects that the temperature of the burner body has reached a predetermined temperature; a prepurge timer circuit which operates a timer from when it is detected that a predetermined temperature has been reached, and whose delay time is longer as the temperature in the room to be heated is lower; and a circuit which operates the ignition device and the electromagnetic pump after the delay time of the timer circuit. A control circuit for an oil vaporization combustor consisting of:
