Reference numeral 54 denotes an air supply blower for supplying outdoor air to the room I through the heat exchanger 53;
Is an exhaust blower for exhausting indoor air to the outside O through the heat exchanger 53, and 56 and 57 are filters.

[0005] When the heat exchange type ventilator constructed as described above is in operation, the outdoor air is supplied to the room I through the filter 56 and the heat exchanger 53 by the air supply blower 54 and the exhaust air blower is provided. 55 causes the indoor air to be discharged to the outside O via the heat exchanger 53 and the filter 57. At this time, the heat exchange between the air supply and the exhaust gas is performed in the heat exchanger 53. For example, the air supply is heated by the heat of the exhaust gas during the heating to prevent a decrease in the room temperature, and the air supply during the cooling. Is cooled by the exhaust to prevent the room temperature from rising.

Similarly, a fan 24 is disposed in the outdoor side hood 18 and is rotationally driven by a motor 25. The fan 24 and the motor 25 constitute a suction type exhaust blower 26. In addition,
As described later, the air supply blower 23 and the exhaust blower 26 are configured to be able to operate individually. 27 is an indoor grill, 28 is an outdoor grill,
These grills 27, 28 serve to fix the cylindrical case 3 in the pipe 2 of the wall material 1.

Next, the operation of the heat exchange type ventilator of the present embodiment configured as described above will be described.

When the ventilator is in operation, the outdoor air is blown by the air blower 23, as shown by the arrow A, into the outdoor air supply passage 10, the air supply passage 7 of the heat exchanger 4, and the indoor air supply air passage. 12 and the indoor I through the indoor hood 13, the indoor air is supplied by the exhaust blower 26, and the indoor exhaust air passage 15, the exhaust passage 8 of the heat exchanger 4, Outdoor exhaust air passage 17 and outdoor hood 18
And is discharged to the outside O through At this time, in the heat exchanger 4, sensible heat and latent heat are exchanged between the supply air and the exhaust air, that is, total heat exchange is performed. For example, during heating, the air supply is heated by the heat of the exhaust air and the indoor air is heated. The temperature is prevented from lowering, and at the time of cooling, the supply air is cooled by the exhaust air to prevent the room temperature from rising.

As described above, at the time of heat exchange, the air supply blower 23 and the exhaust blower 26 are simultaneously operated. In the heat exchange type ventilator of this embodiment, only one of the blowers 23, 26 is used. Since they can be operated individually, the air supply operation can be performed by operating only the air blower 23, or the exhaust operation can be performed by operating only the exhaust blower 26.

On the other hand, the ventilating apparatus of the present embodiment includes the heat exchanger 4, the blowers 23 and 26, and the air passages 10 and 10 in the cylindrical case 3 disposed in the pipe 2 of the wall material 1 as described above.
All members such as 12, 15, 17 are provided, and the interior I and the outside O are ventilated through the inside of the cylindrical case 3. Therefore, it is possible to use the existing pipe 2 for an air conditioner and install it inside the pipe, and it is necessary to newly provide a large mounting hole for installation in the wall material 1 as in a conventional ventilator. There is no.

Further, since most of the cylindrical case 3 is accommodated in the pipe 2, it is possible to prevent the ventilator from protruding largely toward the room I.

As described above, the above embodiment is arranged in the air conditioner pipe 2 penetrating the wall material 1, opens to the room I through the indoor hood 13, and opens through the outdoor hood 18. And a cross-flow type heat exchanger 4 provided with an air supply passage 7 and an exhaust passage 8 which are disposed in the cylindrical case 3 and can exchange heat with each other.
An air supply blower 23 that is provided in the indoor hood 13 and supplies outdoor air to the indoor I through the air supply passage 7 of the heat exchanger 4, and is provided in the outdoor hood 18,
An exhaust blower 26 for exhausting indoor air to the outside O through the exhaust passage 8 of the heat exchanger 4 is provided.

Therefore, the existing air conditioner pipe 2
Since the ventilation device can be provided by utilizing the above, it is not necessary to newly provide a mounting hole for providing the ventilation device in the wall material 1, and the ventilation device can be provided extremely easily.

Further, since most of the cylindrical case 3 is accommodated in the pipe 2, it is possible to prevent the ventilator from protruding largely to the room I side, and to improve the aesthetic appearance of the ventilator from the room I side. It can be greatly improved.

The above embodiment has been embodied in a heat exchange type ventilator which can be installed by using an existing air conditioner pipe 2, but the present invention is not limited to this. Instead, it is only necessary to be able to be disposed in a mounting hole penetrating through the wall material 1. Therefore, it is not always necessary to use an existing mounting hole, and a mounting hole for disposing a ventilation device may be newly provided in the wall material 1. Even in this case, since the ventilation device is compact, the ventilation device can be easily disposed only by penetrating the small-diameter mounting hole.

Although the cylindrical case of the above embodiment is configured as a cylindrical case 3, the present invention is not limited to this case, and the present invention is not limited to this. 2, it is only required to be open to the indoor I side and the outdoor O side. So, for example,
The cross-sectional shape may be polygonal.

Further, the heat exchanger of the above embodiment is of the cross-flow type and is configured as a heat exchanger 4 for exchanging total heat. However, the present invention is not limited to this. Instead, the heat exchanger may be configured as a parallel-flow or counter-flow heat exchanger, or may be configured as a heat exchanger that exchanges only sensible heat by forming a partition plate of metal or the like.

On the other hand, the air supply blower of the above embodiment is provided as a suction type blower 23 which is provided downstream of the air supply passage 7 of the heat exchanger 4 and sucks outdoor air into the indoor I side. The exhaust blower is provided downstream of the exhaust passage 8 of the heat exchanger 4 and is configured as a suction-type blower 26 that sucks indoor air to the outdoor O side. The invention is not limited to this, and any device that can transfer outdoor air or indoor air may be used. Therefore, for example, the supply passage 7 and the exhaust passage 8 of the heat exchanger 4
It may be configured as a push-type blower that is provided on the more upstream side and pushes in outdoor air or indoor air.
