The fluid switching device of this invention shown in FIGS. 1a, b to 4 is configured as described above, so that when ventilation is performed using the heat exchanger 30 during the summer, Upper ventilation hole 3 of exchanger 30
1 and when outdoor air is blown out from the lower vent hole 32, the indoor air is first drawn in through the suction opening 27 provided in the suction member 25 of the fluid suction section 2, and then It passes through the inside of the member 26 and flows into the first fluid chamber 11 of the flow path switching section 1 .

At this time, as shown in the figure, the first opening 15
is opened, and the third opening 17 is closed by the second closing member 20, so that the first fluid chamber 11 and the upper ventilation hole 31 of the heat exchanger 30 are closed.
is connected to the third fluid chamber 13 via the first opening 15, and the second opening 16 is closed by the first closing member 19. 3 fluid chamber 13 and 2nd fluid chamber 1
2, the air flowing into the first fluid chamber 11 flows into the third fluid chamber 13 through the first opening 15 and is sucked into the upper vent hole 31 of the heat exchanger 30. Furthermore, this heat exchanger 3
It is discharged outside through 0.

On the other hand, outdoor air is sucked in through the heat exchanger 30, and the lower ventilation hole 3 of this heat exchanger 30
2 and the fourth fluid chamber 14 of the flow path switching section 1
At this time, as shown in the figure, the third opening 1
7 is closed by the second closing member 20, and the fourth opening 18 is open, so that the fourth fluid chamber 14 and the second
The fluid chamber 12 is in communication with the third fluid chamber 12 through the fourth opening 18, and the second opening 16 is closed by the first closing member 19. Since it is separated from the chamber 13, the air flowing into the fourth fluid chamber 14 flows into the fourth fluid chamber 14.
It flows into the second fluid chamber 12 through the opening 18 and is blown out into the room from the blow-off hole 4 .

In addition, when ventilation is performed using the heat exchanger 30 during the winter period, first, by pulling the extending portion of the strip 22 connected to the second closing member 20 from the casing 3. , from the illustrated state to this reverse state (not shown), that is, the second opening 16
The third opening 17 is opened, the first opening 15 is closed by the first closing member 19, and the fourth opening 18 is closed by the second closing member 20.

This allows the indoor air to flow through the heat exchanger 3 during the winter.
When air is inhaled from the lower vent hole 32 of 0 and outdoor air is blown out from the upper vent hole 31, the indoor air is first inhaled through the suction opening 27 provided in the suction member 25 of the fluid suction section 2. Along with being
The fluid passes through the communication member 26 and flows into the first fluid chamber 11 of the flow path switching section 1 .

At this time, as described above, the first opening 15
is closed by the first closing member 19, and the third

7, and communicates with the fourth opening 1
8 is closed by the second closing member 20, the air that has flowed into the first fluid chamber 11 flows into the fourth fluid chamber 14 through the third opening 17, and also flows under the heat exchanger 30. Inhaled into the ventilation hole 32,
Furthermore, the heat exchanger 30 is used to discharge the heat to the outside.

On the other hand, outdoor air is sucked in through the heat exchanger 30, and the upper ventilation hole 3 of this heat exchanger 30
1 to the third fluid chamber 13 of the flow path switching section 1
At this time, as described above, the first opening 1
5 is closed by the first closing member 19, and the second opening 16 is open, so that the third fluid chamber 13 and the second fluid chamber 12 communicating with the blowout hole 4 are The second fluid chamber 12 and the fourth fluid chamber 14 are separated by communicating through the second opening 16 and the fourth opening 18 is closed by the second closing member 20. The air that has flowed into the third fluid chamber 13 flows into the second fluid chamber 12 through the second opening 16 and is blown out from the blow-off hole 4 into the room.

Therefore, in the heat exchanger 30, the parts of the upper vent hole 31 and the lower vent hole 32, which are used for both air intake and blowout, are switched between the summer period and the winter period. Even if the air flow path is different due to the air flow, the air flow path can be easily switched by using the fluid switching device of this invention. Air is sucked in through the suction opening 27 provided in the suction member 25 and discharged to the outside via the heat exchanger 30, and outdoor air is sucked in through the heat exchanger 30 to connect the flow path switching unit 1.
It is always possible to blow air into the room from the blow-off holes 4 provided in the room, regardless of whether it is summer or winter.

In addition, since the suction opening 27 and the blow-off hole 4 can be placed in a fixed position, when the suction opening 27 and the blow-off hole 4 are connected to a ventilation pipe, it is possible to use the suction opening 27 and the blow-off hole 4 in a fixed position. Therefore, there is no need to replace the piping, and therefore, we have developed a piping pattern that sucks in heavy carbon dioxide gas that remains below the room, discharges it outside, and blows fresh air from outside above the room. This means that it can always be secured without replacing the piping.

[Effect of idea]

By configuring this idea as described above,
Even if the air intake or blowout conditions of the two air intake and blowout holes change between summer and winter, resulting in different air flow paths, the air The flow path can be easily switched, and when using a ventilation pipe connected to the intake or blowout vent, the piping can always be in a fixed piping pattern, so it can be used in both summer and winter. This has excellent effects such as eliminating the need to replace piping.
