First, when it is necessary to operate the apparatus, the main switch is turned on and the second switch 18 is turned on. Eventually, when the room temperature rises and reaches the set temperature of the thermostat 16, a command is issued from the thermostat 16 and the first switch 17 is turned on. Then, the solenoid 11 starts to operate by the power supply from the solar power supply device 22, and the plunger 12 is moved to the solenoid 1
Pull back within 1. Therefore, one end of the first arm 13 connected to the tip of the plunger 12 is also pulled toward the solenoid 11 synchronously, and at the same time, the first arm 13 swings around the locking pin 19 and one end of the first arm 13 moves to the first end. 1 arm 1
The second arm 14 connected to the other end of 3 also swings in synchronization,
The base portion pulls the valve portion 8 connected to the other end of the second arm 14 to open the valve portion 8.

Thus, when the valve portion 8 is brought into the state shown in FIG. 3, the first switch 17 is turned on, so that the exhaust means and the intake device 7 which have started to operate at the same time when the valve portion 8 is opened,
From the exhaust device 4 according to the wind direction 24, indoor air is exhausted to the outside in the order of the exhaust means 7 → valve section 8 → vent port 9 → through cylinder 10, and from the intake device 5 according to the wind direction 25, outdoor air is discharged. Through cylinder 10 → ventilation port 9 → valve section 8 → intake means 7
Will be inhaled indoors in this order.

When the room temperature falls below the temperature set by the thermostat 16, the thermostat 16 operates and issues a command, and the first switch 17 is turned off. Then
The solenoid 11 that has been operated until then stops, and the action of the biasing spring 15 causes one end of the first arm 13 to be pulled together with the plunger 12 toward the biasing spring 15 and at the same time, the first arm 13 causes the locking pin 19 to move. The second arm 14 having one end connected to the other end of the first arm 13 also swings in synchronization with the center, and the base portion presses the valve portion 8 connected to the second arm 14.
