Abstract

PURPOSE:To eliminate the feeling of cold wind during the operation of a cooling fan by shutting off an electric power source when the time of combustion has elapsed a certain time and running a cooling fan for a specified time. CONSTITUTION:When an electric power source switch 10 is turned on, a DC voltage which is reduced through a transformer 4 and which is smoothed by a rectifier 5, a smoothing condenser 6, and a constant voltage diode 8 is given to a gas combustion control electromagnetic valve 12 and a microcomputer 11. When the electric power source switch 10 is operated to be turned off, its signal is sent to the microcomputer 11. Further, the relay 3b of an electromagnetic switch is actuated by signal current from the microcomputer 11, and the contact point 3a connected to this relay is closed to make a fan motor 2 and a plug electrically connected. By this connection the cooling fan rotates. At this time in the microcomputer 11 the turning-on of the electric power source 10 is read off by an electric power switch detection block, and if a combustion detection timer judgement block judges from signal of a combustion flame detector that the combustion time is more than a specified time, starting the fan motor is instructed.

In this hot air heater, in order to prevent the temperature of the appliance from rising after the exhaust source is shut off, it is necessary to cool the appliance with a fan for a considerable period of time. Conventionally, this type of cooling has been achieved by using bimetallic switches or by using capacitors or the like to count the time.

(Problem to be solved by the invention) However, in the method of detecting the temperature using a bimetal switch and cooling the appliance, after the bimetal switch is cooled and turned off, heat conduction from the high temperature part There was a problem that the temperature would rise again and the device would turn on. In addition, the larger the difference in temperature of the warm air corresponding to the strength of the heating, the higher the turning off temperature of the bimetal switch can be set to set the rotation time of the cooling fan within a range that does not give a feeling of cold air when operated strongly. There was also a problem in that the temperature of the bimetal switch did not reach the above-mentioned off temperature when operated weakly, and the temperature of the device rose without being cooled.

(Means for Solving the Problems) In order to solve the two problems, the present invention incorporates the sequence shown in FIG. 1 as a cooling fan on/off determination circuit. That is, in the circuit that determines the combustion time by setting the combustion time reference point T and the cooling time t, the cooling fan does not turn when the combustion time is less than T.
When the rotation time of the cooling fan is 1 or more, the rotation is stopped, and when the rotation time of the cooling fan is less than t and combustion starts again, the cooling fan is turned on regardless of the combustion time T.
