With When the exhaust fan is driven, indoor air is taken in from the exhaust air intake through the heat exchange element into the exhaust passage, and the exhaust passage on the leeward side of the heat exchange element communicates with the toilet air intake. By doing so, the odor of the toilet communicating with the toilet through the toilet exhaust duct from the toilet air inlet is sucked, and the odor can be exhausted to the outside through the exhaust duct.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIGS. (Embodiment 1) As shown in FIGS. 1 to 3, an exhaust air intake 1 is provided on the lower surface, and a Western room 2, a Japanese room 3 and a plurality of rooms such as L and D4 and an air supply duct 5 are provided on one side. A plurality of air supply ports 6 communicated with each other and a toilet air inlet 9 connected to a toilet exhaust duct 8 communicating with the toilet 7;
On the other side, a plurality of ventilation ports 12 connected to an exhaust duct 10 and an outside air intake duct 11 communicating with the outside are provided to form a main body 13, and an air supply fan driven by a motor 14 is provided inside the main body 13. 15 and an exhaust passage 18 provided with an exhaust fan 17 driven by a motor 14 are provided. The exhaust air is taken into the exhaust passage 18 from the exhaust air inlet 1 and the outside air is taken in. A heat exchange element 19 is provided so as to recover exhaust heat between supply air taken into the air supply passage 16 through the duct 11, and the toilet air suction port 9 is disposed on the leeward side of the heat exchange element 19. A louver 21 is provided in a ceiling opening 20 formed to communicate with the passage 18 and formed for attaching and detaching the heat exchange element 19.

In the above configuration, the main body 13 is attached to the ceiling
In the air supply port 6, the Western-style room 2 and the Japanese-style room 3 and L, D4
An air supply duct 5 communicating with a plurality of rooms such as a toilet is connected, a toilet air inlet 9 is connected to a toilet exhaust duct 8 communicating with the toilet 7, and a tape 23 is wound around a connection portion of each duct.

The exhaust fan 1 is driven by the motor 14.
7 and the air supply fan 15, when the air taken in from the exhaust air intake 1 passes through the heat exchange element 19 by the exhaust fan 17, the heat component in the air is reduced by the heat exchange element 1.
9, the exhaust duct 10 connected to the ventilation port 12
And the odor of the toilet 7 is sucked through the toilet exhaust duct 8 from the toilet air suction port 9 communicating with the exhaust passage 18 on the lee side of the heat exchange element 19, and the ventilation port 12. The air is exhausted to the outside via an exhaust duct 10 connected to the air.

On the other hand, when the outside air is taken into the ventilation opening 12 through the outside air intake duct 11 and passed through the heat exchange element 19 by the air supply fan 15, the heat stored in the heat exchange element 19 is recovered. , Fresh air is discharged to the Western-style room 2 and the Japanese-style room 3 and L, D4 communicated from the air supply port 6 through the air supply duct 5.

As described above, according to the ventilation device of the first embodiment of the present invention, the toilet air suction port 9 to which the toilet exhaust duct 8 communicating with the toilet 7 is connected is connected to the exhaust passage on the leeward side of the heat exchange element 19. Because it was provided so as to communicate with 18, it was incorporated into a ventilation system provided so that fresh outside air could be taken in a state where heat was exchanged by the heat exchange element 19 in each room,
A single ventilation system can provide ventilation to exhaust the odor of the toilet, saving the cost of installing a ventilation fan for the toilet and eliminating the need to provide holes in the building wall to install the ventilation fan for the toilet. The degree of spoiling the appearance is reduced.

(Embodiment 2) As shown in FIGS. 4 and 5, the exhaust-side heat exchange element 19a forming the exhaust-side air flow path 25 and the supply-side heat forming the supply-side air flow path 26 are formed. The heat exchange element 19A is formed by laminating the heat exchange element 19b with the exchange element unit 19b, and the exhaust air flow path 25 of the exhaust side heat exchange element unit 19a is formed.
Has a smaller cross-sectional area than the cross-sectional area of the supply-side air flow passage 26 of the supply-side heat exchange element 19b.

In the above configuration, the exhaust fan 17 compares the amount of air supplied through the air supply passage 26 of the heat exchange element 19A by the air supply fan 15 with the amount of air supplied to the exhaust side of the heat exchange element 19A. The amount of exhaust air flowing through the passage 25 decreases, and the leeward side of the heat exchange element 19A is in a negative pressure state.

At this time, the heat exchange element 19 in a negative pressure state
A toilet air inlet 9 is provided on the leeward side of A and communicates with the toilet 7 via the toilet exhaust duct 8.
The odor of the toilet 7 is sucked in so that the negative pressure state is relieved from the toilet air inlet 9, and the exhaust duct 10 is
The air is exhausted to the outside via the.

As described above, according to the ventilating apparatus of the second embodiment of the present invention, the cross-sectional area of the exhaust-side air flow path 25 of the heat exchange element 19A is formed to be smaller than that of the supply-side air flow path 26. Therefore, the odor of the toilet 7 is effectively sucked from the toilet air inlet 9 by utilizing the fact that the ventilation resistance of the exhaust air passage 25 is increased and a negative pressure state is generated on the leeward side of the heat exchange element 19A. Can be exhausted.

Further, by sucking the air from the toilet 7 through the toilet air inlet 9, the load on the air supply fan 15 and the load on the exhaust fan 17 can be made equal, and the rotation of the motor 14 can be stabilized. it can.

Further, since the cross-sectional area of the exhaust-side air flow passage 25 of the heat exchange element 19A is reduced so as to increase the ventilation resistance, odor from the toilet can be reduced.
A can also be prevented from flowing into the room from the exhaust air inlet 1 through A.

[0023]

As is apparent from the above embodiment, according to the present invention, a plurality of air supply units having an exhaust air intake on the lower surface and communicating with a plurality of rooms on one side through an air supply duct are provided. A body provided with a toilet air intake port connected to a mouth and a toilet exhaust duct communicating with the toilet, and a vent provided on the other side surface with an exhaust duct communicating with the outside and a ventilation port connected to an outside air intake duct; An air supply fan and an exhaust fan provided in each of an air supply flow path and an exhaust flow path which are defined and formed inside, and exhaust air taken in from the exhaust air intake and intake through the outside air intake duct A heat exchange element provided so as to recover exhaust heat between the supply air and the supply air, and the toilet air suction port is connected to an exhaust passage on the leeward side of the heat exchange element. system Unification can, eliminates the installation cost of the toilet for the ventilators, it is possible to provide that no ventilation system to impair the appearance of the building.

Further, a heat exchange element formed by laminating a single exhaust heat exchange element forming an exhaust air flow path and a single supply air heat exchange element forming a supply air flow path is provided. ,
Since the cross-sectional area of the exhaust-side air flow path of the exhaust-side heat exchange element alone is formed to be smaller than the cross-sectional area of the supply-side air flow path of the air supply-side heat exchange element alone, ventilation of the toilet is ensured. The rotation of the motor can be stabilized by making the loads of the ventilation fan and the air supply fan the same.
