A plurality of wind collectors 110 provided with a plurality of 9 are arranged so that the lengths of the small-diameter flexible tubes 108 are substantially the same.

[0005]

In such a conventional ventilator, when a small-diameter flexible tube is connected to the vents of a plurality of rooms on the second floor and the first floor, the vent 10 on the first floor is connected.
Compared to the small-diameter flexible tube 108 connected to the third floor, the small-diameter flexible tube 108 connected to the vent 103 on the second floor is longer to rise from the back of the first floor to the back of the ceiling on the second floor, and the length of the small-diameter flexible tube 108 is longer. Cannot be provided at positions where the lengths are substantially the same, the balance of the air volume from the ventilation opening 103 on the first floor and the ventilation opening 103 on the second floor is poor, and a plurality of small-diameter flexible tubes 108 are connected. There is a problem that the workability is poor because it is necessary to start up from the first floor ceiling 111 to the second floor ceiling 112.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a ventilation device which can obtain substantially the same amount of ventilation air from each ventilation hole of each floor and has good workability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is directed to a vent provided in a plurality of rooms on each floor where ventilation of a house is required, and a vent for each floor provided with the vent. It has a suction port to which a small-diameter flexible tube connected to the port is connected, and a discharge port to which a large-diameter flexible tube is connected, and is provided in communication with a ventilator provided behind the ceiling of each floor and the outdoor. A ventilator for exhaust air, wherein the ventilator is connected to the ventilator on each floor via a flexible tube having a large diameter. The air in each room is sucked from the vents provided in each of the multiple rooms, flows through the small-diameter flexible tubes, and is sucked into the collectors on each floor, and is larger than the collectors. Sucked into the flow blower, will be exhausted to the outdoor, with the effect that workability even better it is possible to ventilate the substantially same air volume than the respective vents each floor.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG.

(Embodiment 1) As shown in FIG. 1, vents 1 are provided in a plurality of rooms on each of the first and second floors where ventilation of a house is required, and are provided in communication with the vents 1. A ventilator 6 having a suction port 3 to which a small-diameter flexible tube 2 is connected and a discharge port 5 to which a large-diameter flexible tube 4 is connected is provided on the ceiling back 7 of each floor.
An air blower 9 for exhaust, which is provided in communication with the ceiling, is provided on the ceiling floor 7 on the first floor.

Then, the small-diameter flexible tube 2 is formed by connecting the ventilation port 1 of each floor of the ventilation port 1 provided in each of a plurality of rooms on each floor and the suction port 3 of the air collector 6 provided on each floor.
A branch pipe 10 is provided on the suction side of the blower 9, and a large-diameter flexible tube 4 having a short length is connected to one branch port of the branch pipe 10. It is connected to the discharge port 5 of the collector 6, and a long large-diameter flexible tube 4 that can rise up to the ceiling 7 on the second floor is connected to the other branch of the branch pipe 10. 7 and is connected to the discharge port 5 of the air collector 6 provided at 7.

The small-diameter flexible tube 2 and the large-diameter flexible tube 4 are configured to be reduced in length by applying an external force, and to be restored to the original length when no external force is applied.

In the above configuration, when the blower 9 is operated, the air in the room 11 is sucked from the vents 1 provided in a plurality of rooms on each of the first and second floors and flows through the flexible tube 2 having a small diameter. Then, the air is sucked into the air collector 6 on each floor, passed through the flexible tube 4 having a larger diameter than the air collector 6, sucked into the blower 9, and exhausted to the outside 8.

At this time, a wind collector 6 is provided on the ceiling back 7 of each floor at a position where the length of each small-diameter flexible tube 2 is substantially the same.

The length of the large-diameter flexible tube 4 connected to the blower 9 and the air collector 6 differs for each floor, and is longer for the second floor.
Since the number of rooms on the second floor is smaller than the number of rooms on the floor, the number of vents 1 on the second floor is smaller than that on the first floor, and the large standing room 7 rises from the ceiling 7 on the first floor to the ceiling 7 on the second floor. Since the amount of air flowing through the flexible tube 4 having a small diameter is small, the decrease in the amount of air due to the length of the flexible tube 4 having a large diameter is small.

As described above, according to the ventilating apparatus of the first embodiment of the present invention, the length of the small-diameter flexible tube 2 is substantially the same, and the length of the large-diameter flexible tube 4 differs between the first floor and the second floor. However, since the decrease in air volume is small,
It is possible to ventilate almost the same amount of air from the vents 1 provided in each room on the first floor and the second floor, and to connect one large-diameter flexible tube 4 from the first floor ceiling 7 to the second floor ceiling 7. Construction is also easy because it only needs to be started.

Further, by making the collectors 6 provided on the first floor and the second floor have the same shape, the ventilation resistance becomes the same, and ventilation with a uniform air volume becomes possible.

Further, since the small-diameter flexible tube 2 and the large-diameter flexible tube 4 are made to be elastic, the number of packing at the time of packing can be reduced, the transportation cost is low, and the transportation on site is easy. At the time of unpacking, the original length is naturally restored, so the workability is improved.

(Embodiment 2) As shown in FIG. 2, a blower 9A is provided with a plurality of large-diameter suction ports 12 to which large-diameter flexible tubes are connected, and a large-diameter collector 6 provided on each floor. The connection is made via a flexible tube 4 having a diameter.

When the air blower 9A is operated in the above configuration, the air in the room 11 is sucked in from each of the air vents 1, passes through the flexible tube 4 having a larger diameter than the air collector 6, and is blown from a plurality of large diameter inlets 12. The air is sucked into the device 9 </ b> A and exhausted to the outside 8.

As described above, according to the ventilator of the second embodiment of the present invention, since the blower 9A is provided with the plurality of large-diameter suction ports 12, the plurality of large-diameter flexible tubes 4 are provided.
Can be connected, so that the large-diameter flexible tube 4 does not branch, so that the air volume flowing through the plurality of large-diameter flexible tubes 4 does not flow into one large-diameter flexible tube 4 and the pressure loss is reduced. And power consumption is reduced.

[0023]

As is clear from the above embodiment,
According to the present invention, a ventilator is provided behind the ceiling of each floor, and a plurality of small-diameter flexible tubes communicating with a plurality of vents provided in a plurality of rooms are provided on the suction side of each ventilator, and on the discharge side. Since a single blower is connected via a large-diameter flexible tube, it is possible to provide a ventilator that can ventilate substantially the same air volume from the ventilation holes on each floor and that is easy to construct.

Further, since the air collectors provided on each floor have the same shape, a substantially uniform air volume can be ventilated from each room.

Further, since the blower is provided with a plurality of large-diameter suction ports to which the large-diameter flexible tubes are connected, pressure loss is reduced and power consumption can be reduced.

Further, since the small-diameter flexible tube and the large-diameter flexible tube are reduced by applying an external force, and are restored to the original length when no external force is applied, the number of packing is reduced, and The cost is low, and transportation on site can be facilitated.
