DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator for ventilating each room such as a washroom, a water heater and the like.

[0002]

2. Description of the Related Art A conventional ventilation device will be described with reference to FIG. In FIG. 2, reference numeral 1 denotes a building, 2a, 2b,...
Each of the intake ports 2a, 2b,.
are connected to the exhaust main duct 4 via a, 3b,.

The main exhaust duct 4 is connected to an exhaust fan 5 with a motor 5a installed on the roof of the building 1. In the conventional ventilator configured as described above, when the exhaust fan 5 with the motor 5a is driven, the air in each room is converted into the corresponding intake ports 2a, 2b,.
And is discharged to the atmosphere through the branch ducts 3a, 3b... And the exhaust main duct 4.
Thereby, ventilation of each room can be performed.

[0004]

However, in the conventional ventilating apparatus described above, in order to ventilate each room, the motor 5a must be energized and the exhaust fan 5 must be constantly operated.

[0005] For this reason, there has been a problem that the consumption of electric energy is large and the operating cost is increased. The present invention has been made in view of the above-described circumstances, and an object of the present invention is to control the switching from forced ventilation to natural ventilation by an exhaust fan using the wind power when there is wind power exceeding a certain level. To provide a ventilating device that has a reduced capacity.

[0006]

According to the present invention, there is provided a ventilating apparatus comprising: an exhaust duct connected to an intake port of each room of a building; an exhaust fan connected to the exhaust duct for forcibly ventilating each room; A ventilator connected to a duct and naturally ventilating each room by wind power, a motor damper for opening and closing the passage between the exhaust duct and the exhaust fan and the ventilator, an anemometer for measuring a wind force and outputting a signal, and the anemometer It is determined whether or not the wind power is equal to or greater than a predetermined set value based on the signal output from the controller.When the wind power is equal to or greater than the set value, the motor damper is controlled to connect the exhaust duct to the ventilator. Control means for controlling the motor damper to connect the exhaust duct to the exhaust fan at the following times and for controlling the drive of the exhaust fan. .

[0007]

In the present invention, when the control means determines that the wind power measured by the anemometer is equal to or greater than the set value, the motor damper is opened, the exhaust duct is connected to the ventilator, and each room is naturally ventilated by the wind ventilator. I do.

When the control means determines that the wind force is equal to or less than the set value, the motor damper opens to communicate the exhaust duct with the exhaust fan, and the exhaust fan is driven to forcibly ventilate each room.

Therefore, it becomes possible to switch and control the ventilation by the exhaust fan to the natural ventilation by the ventilator according to the wind force.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram of an embodiment in which the present invention is applied to a building ventilation device.

In FIG. 1, 1 is a building, 2a, 2b,.
Are intake ports installed in washrooms, kettle rooms, etc. on each floor, and each of the intake ports 2a, 2b... Is a main duct for exhaust through branch ducts 3a, 3b. 4 is connected.

[0012] The upper end of the exhaust main duct 4 is
It is connected to a ventilator 6 for natural ventilation installed on the rooftop through a motor damper 7 for opening and closing a passage. further,
The upper end of the exhaust main duct 4 is connected via a branch duct 9 to an exhaust fan 8 with a motor 8a installed on the roof of the building 1, and a motor damper for opening and closing the passage of the branch duct 9 is provided in the middle of the branch duct 9. 10 are provided.

Reference numeral 11 denotes an anemometer installed on the roof of the building 1, and a signal output according to the wind power measured by the anemometer 11 is input to a control device 12. Control device 1
Numeral 2 controls opening and closing of the motor damper 7 for the ventilator and the motor damper 10 for the exhaust fan in accordance with an output signal from the anemometer 11, and also controls on / off of the exhaust fan 8.

On the roof of the building 1, a solar panel 13 made of silicon solar cells is installed.
Is used as a power supply for driving the motor dampers 7, 10 and the control device 12.

Next, the operation of the present embodiment configured as described above will be described. When an output signal from the anemometer 11 is input to the control device 12, the control device 12 determines from the input signal whether the current wind is a wind required for natural ventilation (for example, 2 m / sec or more). .

Here, the wind power required for natural ventilation is less than 2 m (2 m).
/ Sec or less), the controller 1
In step 1, the motor damper 7 is closed, the motor damper 10 is opened, and the motor 8a of the exhaust fan 8 is started.

As a result, each room of the building 1 is forcibly ventilated by the exhaust fan 8. On the other hand, the control device 12 determines that the current wind speed is higher than the wind speed required for natural ventilation (2 m
/ Sec or more), the controller 12
The motor damper 7 is opened by the control command from the
The motor damper 10 is operated in the closed state.

At the same time, the exhaust fan 8 is stopped. As a result, since the exhaust main duct 4 is communicated with the ventilator 6, the air in each room is semi-forcibly sucked by the wind passing through the ventilator 6, and each room is naturally ventilated.

In the ventilation device of this embodiment, when the wind power measured by the anemometer 11 is equal to or higher than the set wind power, the motor damper 10 for the exhaust fan is closed, the exhaust fan 8 is stopped, and the motor damper for the ventilator is stopped. 7, the main duct 4 for exhaust is connected to the ventilator 6, and the ventilator 6 is operated so that each room is naturally ventilated. When the wind power is less than the set wind force, the exhaust fan 8 is operated to control and ventilate the room. So that
Electric energy consumption can be significantly reduced compared to conventional ventilation systems, and electricity costs can be reduced.

Further, since the control device 12 and the motor dampers 7, 10 can be driven by using the electric power generated by the solar panel 13, energy saving can be further promoted.

In the above embodiment, since the wind power changes every moment, if the value measured by the anemometer 11 fluctuates frequently based on a set value, hunting occurs in the motor dampers 7 and 10. As a method for preventing this hunting, a delay timer may be incorporated in the control device 12.

Further, in the above-described embodiment, the case where power is supplied to the control device 12 and the motor dampers 7 and 10 using the solar panel 13 has been described. However, the present invention is not limited to this. May be used.

Further, the present invention is not limited to the configuration shown in the above embodiment, and various modifications can be made without departing from the scope described in the claims.

[0024]

As described above, according to the present invention, an exhaust fan with a motor and a ventilator for natural ventilation are connected to an exhaust duct connected to an intake port of each room of a building via a motor damper, and the anemometer is used. When the measured wind is above the set value, the exhaust duct is switched to the ventilator side to allow each room to ventilate naturally, and when the wind is below the set value, the exhaust duct is switched to the exhaust fan and the exhaust fan is driven to drive each room. Is forcedly ventilated, so that the consumption of electric energy and the cost of electricity can be greatly reduced, and there is an effect that energy can be saved.
