Description of the Related Art Conventional ventilation fans for multiple rooms have been constructed as shown in FIGS. e and 7, for example, although no specific references can be cited. That is, the base unit 101 and the slave unit 102 are connected by a duct 103, and the ventilation fan 104 is provided only in the base unit 101, and is not provided in the slave unit 102. Here, since the intake passage on the main unit 101 side is shaped to have an overwhelmingly smaller ventilation resistance than the intake passage on the slave unit 102 side, the intake air volume on the main unit 101 side is smaller than that on the slave unit 102 side. big. Normally, the installation location (room) is selected taking into consideration this difference in intake air volume, but
If you want to increase the ventilation capacity on the second side, as shown in FIG.
By partially blocking 6 with a shielding plate 107, the suction air volume of the master unit 101 is reduced, and the suction air volume of the slave unit 102 is increased by that amount.

なる。When installing the multi-room ventilation fan configured as described above, first, check the size of the rooms of bathroom A and washroom B where the main suction port 1A and sub-suction port 1B communicate with each other, and the size of the air intake duct 3. When the variable resistor 10 is adjusted in consideration of the construction condition, the signal E of the movable piece 10a of the variable resistor 10 is and the signal F from the position detection piece 11 in the damper unit T that adjusts the air volume.
The light emitting side 7 (J, 7k) of the photocoupler is made to emit light, and the motor 7a is rotated according to the sequence shown in Fig. 3 so that the signal F becomes equal to the signal E, and the opening area of the main suction port 1A is The ratio of the suction air volume between the main suction port 1A and the sub suction port 1B is adjusted by adjusting the ratio of the suction air volume between the main suction port 1A and the sub suction port 1B. If the signal E is larger than F, the second photocoupler's light emitting sensor 7k is applied with a reverse bias voltage and does not emit light, but the first photocoupler's light emitting device IJIIJ 7q is applied with a forward bias voltage. The light is emitted, the drive circuit 7f becomes conductive and the excitation coil 7e of the relay is energized, and the a contact 7d is closed (ON) L.
, the motor 7a rotates in reverse and operates in the direction of closing the door. Then, in conjunction with the rotation of the motor 7a, the position detection piece 11
When the signal F is increased and the signal E and the signal F become equal, the state shown in FIG. 3 (3) is reached, both the a contacts yd and γh are opened (OFF) and the motor 7a stops. The damper is fixed, and the ratio of the suction air volume between the main suction port 1A and the sub suction port 1B is adjusted. Next, when the multi-room ventilation fan is operating in this state, a large amount of steam suddenly occurs from the bathtub in bathroom A during bathing, etc., and the humidity in the bathroom increases, the humidity sensor 8 detects this. Its resistance value increases and the signal E
The magnitude of signal F becomes smaller than the magnitude of signal F, as shown in FIG.
), the motor 7a rotates forward, that is, rotates in the direction of opening the damper, increasing the amount of suction air from the main suction port 1A and decreasing the amount of suction air from the sub suction port 1B, thereby performing ventilation. On the other hand, if the humidity in bathroom A is low and someone is in washroom B, the human body detection sensor may be activated. 9 detects a human body, the resistance value increases, the magnitude of signal E becomes larger than the magnitude of signal F, and the state shown in Fig. 3 (1) is reached, the damper moves in the closing direction, and the damper moves from the sub suction port 1B. increases the suction air volume of
Ventilation will be performed by reducing the intake air volume from the main suction port.

あるのでその説明は省略する。また夏場、あるいは臭気
等が強い場合は、人間の感性から強力に換気したいので
、上記と逆に可変抵抗体12を変化させて換気風量を増
大させる。If both Bathroom A and Washroom B are constantly ventilated (ventilation is performed under conditions where there are no sudden changes), and someone enters the washroom, for example in the winter, strong ventilation may cause the cold. Since it feels uncomfortable, a person manually removes the variable resistor 1.
Change the resistance value of 2 to reduce the ventilation air volume. The operation of the damper unit 7 at this time is the same as that in the first embodiment, so a description thereof will be omitted. Furthermore, in the summer or when there is a strong odor, strong ventilation is desired based on human sensitivity, so the variable resistor 12 is changed in the opposite way to the above to increase the ventilation air volume.

果の異なるものではない。In this embodiment, the variable resistor 12 is installed in the washroom B as a variable resistance element, but when it is installed in the bathroom A and the air volume is manually adjusted when taking a bath in winter, the variable resistor 12 is installed in the other washroom B. Even if the human body detection sensor 9 is provided, the operation and effect are not different from those of the above embodiment.

なる多室用換気扇。(2) The opening on the bottom of the ventilation fan body with one built-in blower communicates directly with the room to serve as the main suction inlet, and the opening on at least one side of the fan body communicates with the other room via an intake duct to serve as a secondary inlet. A damper that adjusts the opening area of at least one of the main suction port and the auxiliary suction port to adjust the ratio of ventilation air volume between each room is installed as a suction port in at least one of the rooms, and a damper is installed in at least one of the main suction ports and a damper that adjusts the ratio of ventilation air volume between the rooms. A multi-chamber system comprising a sensor for detecting a change in the temperature, a manually operated variable impedance body in another chamber, and a control means for controlling the operation of the damper in response to the outputs of the sensor and the variable impedance body in the damper. ventilation fan.
