に変換するものである。In Figure 1, 1 is a microcomputer with a CPU,
It is a so-called one-chip microcomputer having ROM, RAM, :# and an input/output section, and the operation sequence of the hot air heater is programmed and built-in. Reference numeral 2 denotes room temperature detection means consisting of an electronic circuit including a thermistor, and reference character a indicates room temperature setting means, the output signal of which is input to the gas amount calculation means 4 in the microcomputer 1 together with the signal output from the room temperature detection means 2. The gas amount calculating means 4 calculates the required gas amount based on the set room temperature and the room temperature signal, and outputs a voltage signal. Reference numeral 5 denotes voltage-to-current converting means for converting the voltage signal from the gas l calculation means 4 into a current signal to be passed through the gas proportional valve 13.

維持する。To explain its internal configuration, reference numeral 6 constitutes a voltage follower by an operational amplifier, and is connected to a non-inverting input terminal of an operational amplifier 7. 8 is a resistor, and the operational amplifier 7
9 is a bias resistor of the transistor 11, and 10 is a resistor that protects the output terminal by limiting the output current of the gas proportional valve 13.
It generates a voltage proportional to the value of current flowing through the circuit, and is connected to the inverting input terminal of the operational amplifier 7 via a resistor 12. Therefore, the operational amplifier 7 operates as a positive-phase amplifier, and the voltage at the output terminal increases until the voltage at the non-inverting input terminal and the voltage at the inverting input terminal become equal.As a result, the base current of the transistor 11 increases and the proportional valve 13 increases. The current flowing through the circuit increases. Then, the voltage generated across the resistor 10 is the voltage generated across the resistor 12.
When the voltage enters the inverting input terminal via the inverting input terminal and becomes equal to the voltage at the non-inverting input terminal, the voltage at the output terminal stops rising and maintains that state.

間だけ動作させる働きを行う。Next, 14 is a proportional valve current increasing means, which is connected to the base of the transistor 18 via a resistor 15.degree. 16 based on a signal from the microcomputer 1. A resistor 17 is connected in parallel to the series circuit of resistors 10 and 12 of the voltage-current converting means 5 when the transistor 18 is turned on. As a result, even though the voltage at the inverting input terminal of the operational amplifier 7 decreases, the current flowing through the gas proportional valve 13 further increases. Reference numeral 19 is a timer means programmed in the microcomputer 1, which operates the proportional valve current increasing means 14 for a predetermined period of time.

御を行う。FIG. 2 shows the operation flow of an embodiment of the present invention, and FIG. 3 shows changes in output and temperature over time. After the start of operation, if the room temperature is lower than a predetermined temperature T programmed in the microcomputer 1, the timer means 19 shown in FIG. 1 operates the proportional valve current increasing means 14 to operate the heating output at α. If the room temperature is higher than the predetermined temperature T, temperature control is performed so that the output falls within the rated output range and reaches the set temperature Ts. After starting operation with the output α, the timer means 19 stops the operation of the proportional valve current increasing means 14 after a predetermined time ta, and the temperature is controlled within the normal rated output range.

As a result, the room temperature rises as shown in FIG. 3B (it is possible to reach the set temperature T$ tβ time earlier than in the conventional A).
