The high-temperature and high-humidity air generated at this time is carried by the regeneration fan 2, cooled by the condenser 11, separated as moisture, and stored in the tank 8. The regenerative heater 3 or the condenser 11 is provided with a regenerative heater thermistor 4 and a temperature sensor 10 in the ventilation path 1a as temperature detecting means for detecting a high temperature abnormality.

  The control device 5 receives input signals from an operation switch (not shown) of the operation unit 6 and a humidity sensor 14 for detecting temperature and humidity, the regenerative heater thermistor 4 or the temperature sensor 10, and the like. It controls the operation of the regeneration fan 102 and the like.

  In the above configuration, when the operation is started (step 1-1), the regenerative heater 3 which is a heating means is energized. (Step 1-2) The energization time is set in the microcomputer 5a mounted on the control unit 5. When the energization of the regenerative heater 3 is started, the microcomputer 5a starts the timer count T1 (step 1-3), and the temperature sensor 10 disposed in the condenser 11 and the regenerative heater thermistor 4 disposed in the vicinity of the regenerative heater 3 are used. Start temperature sampling. The microcomputer 5a always compares the temperature detected by the temperature sensor 10 and the regenerative heater thermistor 4 with a preset abnormal temperature (step 1-4). When the abnormal temperature is exceeded, the microcomputer 5a enters an abnormal mode (step 1-). 4A) Stop the equipment safely. If the abnormal temperature is not exceeded, energization of the regenerative heater 3 is continued until the timer count value T1 reaches a predetermined Ton time. When T1> Ton (step 1-5), the microcomputer 5a resets the timer count value T1 (step 1-6) and stops energization of the regenerative heater 3 (step 1-7). Further, the microcomputer 5a starts the timer count T2 (step 1-8) and continues to stop the energization of the regenerative heater 3 until the timer count value T2 reaches a predetermined Toff time (step 1-9). ).

Counting is started (step 2-7). The microcomputer 5a continues energization of the regenerative heater 3 until the time Ton (step 2-3B and step 2-4) set by the room temperature is reached. When T1> Ton (step 2-8), the microcomputer 5a stops energization of the regenerative heater 3 (step 2-9), and newly starts counting the energization stop time count T2 of the regenerative heater 3. (Step 2-10). The microcomputer 5a continues to stop energization of the regenerative heater 3 until the count value T2 reaches a preset time Toff. When the timer count value T2> Toff (step 2-11), the microcomputer 5a samples the temperature sensor 10 or the regenerative heater thermistor 4, and the detected room temperature is below a predetermined set temperature. If there is (step 2-12), the T2 count value is reset (step 2-13), Ton is set to 10 minutes (step 2-4), and energization of the regenerative heater 3 is resumed. This is repeated thereafter.

Thereafter, the energization time T1 of the regenerative heater 3 is reset, the energization of the regenerative heater 3 is started (step 3-8), and the timer T1 is newly counted (step 3-9). The microcomputer 5a continues energizing the regenerative heater 3 until the time Ton (step 3-6) set by the room temperature is reached. When T1> Ton (step 3-10), the microcomputer 5a stops energization of the regenerative heater 3 (step 3-11). However, the operation of the blower fan 1 and the regeneration fan 2 continues (step 3-12). Thereafter, the timer count Ts ′ is continued until the energization stop time of the regenerative heater 3 and the time Ts set in advance as the air blowing time of the blower fan 1 and the regenerative fan 2 are reached. When the timer count value Ts ′> Ts is satisfied (step 3-4), the microcomputer 5a detects the temperature of the temperature sensor 10 disposed near the condenser 11 and the temperature of the regenerative heater thermistor 4 disposed near the regenerative heater 3. Sampling is started (step 3-5), and this is repeated thereafter.

  As described above, when the detected temperature of the temperature sensor 10 or the regenerative heater thermistor 4 is equal to or higher than the room temperature threshold, the microcomputer 5a sends the detection timing and re-detects the room temperature. While the operation is stopped, the regenerative heater 3 can be controlled by accurately detecting the room temperature by continuing the operation of the blower fan 1 at least.
