Accordingly, an object of the present invention is to provide a comfortable heating device in which cool air is not blown by a blower at the time of ignition.

[Constitution of the Invention] (Means for Solving the Problems) The present invention relates to a room temperature detector for detecting a room temperature, and ignition of the combustion unit in a heating device for blowing air heated in the combustion unit as warm air by a blower. Ignition detection means for detecting
When ignition of the combustion part is detected by the ignition detection means, a room temperature detection signal is received from the room temperature detector and compared with the set temperature.If the room temperature is higher than the set temperature, the start of the blower is quicker and the room temperature is higher than the set temperature. And a blower control means for delaying the start of the blower if lower.

(Operation) With the provision of such a means, when ignition of the combustion part is detected by the ignition detection means, the air blowing control means receives a room temperature detection signal from the room temperature detector and compares it with the set temperature. If the temperature is higher than the set temperature, the start of the blower is accelerated, and if the room temperature is lower than the set temperature, the start of the blower is delayed.

Is connected. The photodiode 42 is photocoupled with the phototransistor 33,
The photodiode 43 is photocoupled to the phototriac 29.

When the ignition detector 39 detects the ignition of the burner 7, the microprocessor 36 receives the room temperature detection signal from the room temperature detector 15 and compares it with the set temperature. If the room temperature is higher than the set temperature, the microprocessor 36 It has a function of speeding up the start and delaying the start of the blower 14 when the room temperature is lower than the set temperature.

Next, the operation of the apparatus configured as described above will be described with reference to the air flow control flowcharts shown in FIGS.
When the operation button 24 is closed while the power is turned on and the power is supplied to the microprocessor 36, the operation start detection switch 37 is closed in conjunction with the operation button 24. At this time, the microprocessor 36 detects the closing of the operation start detection switch 37 to determine the operation start, and causes the photodiode 43 to emit light. As a result, a gate current is supplied to the gate of the triac 26 through the phototriac 29, and the triac 26 becomes conductive. Electric power is supplied to the vaporizer heater 25 due to the conduction of the triac 26, and the vaporizer 6 is heated. And the microprocessor

Flash. The switch 31 is closed by the energization of the relay coil 40, and the coil 5a of the electromagnetic pump 5 is closed.
And the ignition transformer 32 is supplied with electric power. However,
The electromagnetic pump 5 operates to suck up the oil in the fuel tank 3 and supply it to the vaporizer 6. Since the vaporizer 6 is already heated, the oil is vaporized and supplied to the burner 7 from the nozzle. Then, when the timer time in the ignition transformer 32 elapses, a spark is generated from the ignition transformer 32.
Thus, the burner 7 is ignited and the combustion is started.

At this time, the ignition of the burner 7 is detected by the ignition detector 39. The microprocessor 36 determines the ignition based on the ignition detection signal from the ignition detector 39,
The room temperature detection signal from 15 is taken in and the processing is executed according to the air flow control flow chart shown in FIG.

The power supply to the electromagnetic pump 5 and the ignition transformer 32 is cut off. However, the combustion in the burner 7 stops. By the way, when the operation start detection switch 37 is opened, the microprocessor 36 determines that the digestion has been performed and executes the processing of the air blowing control shown in FIG. That is, the microprocessor 36 takes in the room temperature detection signal from the room temperature detector 15, obtains the room temperature T and temporarily stores the room temperature T. In step e1, it determines whether or not the room temperature T is higher than the set temperature 25 ° C. Move to step e2. In this step e2, it is determined whether or not the room temperature T is between the set temperature of 15 ° C. to 25 ° C. If the room temperature is not within the set temperature range, the process proceeds to step e3. Therefore, the microprocessor 36 sets the room temperature T to 25 ° C. in step e1.
If it is determined that this is the case, the elapse of the time 60 [sec] is waited for in step e4, and the energization of the relay 41 is released in step e6. As a result, the switch 23 is switched to the ground side, and the drive of the blower motor 14b stops. The room temperature T is 1
If it is determined that the temperature is within the range of 5 ° C. to 25 ° C., time e 30
After waiting for the elapse of [sec], the drive of the blower motor 14 is stopped in step e6. Further, if it is determined that the room temperature T is 15 ° C. or less, the drive of the blower motor 14 is stopped in step e6 after elapse of a time of 10 [sec] in step e3.

As described above, in the above embodiment, when the ignition of the burner 7 is detected, the room temperature detection signal from the room temperature detector 15 is received and compared with the set temperature. If the room temperature is higher than the set temperature 10 ° C., the blower 14 quick start and room temperature is 0 ° C
If it is lower than this, the start of the blower 14 is delayed, so that the warm air can be reliably blown and comfortable heating can be performed. In addition, since the room temperature detector is provided in a normal heating device, it is not necessary to particularly provide the room temperature detector and other electric elements. Further, even when the start control of the blower 14 as described above is performed, no excessive force is applied to the apparatus itself.

The present invention is not limited to the above-described embodiment, and may be modified without departing from the gist thereof. For example,
