Abstract

PURPOSE:To perform local ventilation in large quantities accurately by separating a heat exchanger and an air blower room with a partitioning plate, and providing an opening of a partitioning plate in an exhaust duct inside the air blower room and a damper opens/closes at the connecting position of a local exhaust duct with a through hole. CONSTITUTION:At the time of normal operation, a through hole 47 is closed by a damper 58, and by operating a suction fan 54 and an exhaust fan 56, air is exhausted from each room through an exhaust port 34 and passes through a total heat exchanger 30 from a first exhaust duct 35, and to the outside from a second exhaust duct 41 through the opening 57 of a partitioning plate 48. For example, when a toilet room 44 is used, the damper 58 closes the side of the opening 57 and opens the through hole 47, and air is induced from a local exhaust port 45 by the exhaust fan 56, passes through a local exhaust duct 46, and exhausted to the outside through the duct 41. Therefore, large quantities of odorous air can be promptly exhausted from the through hole 47 without passing through the total heat exchanger 30 and cusing resistance.

Problems to be Solved by the Invention In such a conventional configuration, the intake flow path 17 and the exhaust flow path 1
The heat exchanger 16 at 6 acts as a ventilation resistance, and when it is desired to exhaust a large amount of air, such as exhausting odor from a toilet, expelling damp air from a bathroom, or expelling cooking odor from a kitchen, the heat exchanger 16 acts as a ventilation resistance. 16, which was inconvenient.

The present invention solves these problems and provides a heat exchange air unit that can reliably and locally exhaust a large amount of air.

Means for Solving the Problem In order to solve this problem, the present invention divides the main body into a heat exchange room in which a total heat exchanger is provided and a blower room in which an intake fan and an exhaust fan are provided using a partition plate. The exhaust duct of the heat exchange chamber passes through the total heat exchanger, the opening formed at one end of the partition plate, and an exhaust passage through which the exhaust fan passes, and the intake duct passes through the intake fan and the total heat exchanger. and a local exhaust duct having a communication port near the opening of the partition plate of the blower room, and the opening of the partition plate of the exhaust flow path and the communication port of the local exhaust duct are opened and closed. A damper is provided, and the damper normally opens a partition plate opening, and opens a communication port of the local exhaust duct when the local room is evacuated.

Effect With this configuration, when a resident wants to exhaust as much air as possible from a local room such as a toilet, the partition plate opening side of the exhaust flow path is closed by a damper, and the air is discharged from the communication port of the local exhaust duct via an exhaust fan. When a large amount of air is exhausted outdoors and normal ventilation is performed, the partition plate opening is opened using a damper and ventilation is performed through the intake flow path and the exhaust flow path.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In FIG. 2, the main body 31 of the heat exchange air unit is suspended and installed in the ceiling.

The main body 31 and the room are connected via a first exhaust duct 35 connected to an exhaust port 34 provided on the ceiling surface 32 on the first floor and the floor 33 on the second floor, and also connected to the ceiling surface 32 on the first floor and the floor 33 on the second floor. 33
A first intake duct 38 connected to an air outlet 37 provided in
It is configured such that the air is connected through the air outlet 37 of each chamber and the air is blown out from the air outlet 37 of each chamber. The main body 31 and the outside communicate with each other through a second exhaust duct 41 provided on the side of the main body 31, and also through a second intake duct 43 provided on either side of the main body 31. Further, a local exhaust duct 46 is connected to a local exhaust port 46 provided on the ceiling of the toilet room 44.
The other end of 6 is connected to a communication port 47 (first
(Figure).

FIG. 1 shows the structure of the main body 31. The interior of the main body 31 is divided into a total heat exchange chamber 49 and a blower chamber 6 by a first partition plate 48.
The blower chamber 60 is provided with an intake fan 54 and an exhaust fan 66, and the total heat exchange chamber 49 is provided with a total heat exchanger 3°. An opening 67 is formed at one end of the partition plate 48 to serve as the main exhaust flow. A communication port 47 of the local exhaust duct 46 is formed near the opening 67 of the blower room 6o, and a damper 68 is provided to open and close this opening 67 or to open and close the communication port 47. Inside the main body 31 is a second intake duct 43 on the outside air side. Intake fan 64° Total heat exchanger 3

The air is exhausted from the second exhaust duct 41 to the outside. At the same time, the outside air is taken in through the second intake duct 43, passed through the total heat exchanger 3o by the intake fan 64, and then sent through the intake duct 38 to each room while recovering the heat in the exhaust gas. ventilation.

Here, if the toilet room 44 is used, the damper 58
In this case, the partition plate opening 57 side is closed and the communication port 47 is opened. Then, the air is drawn through the local exhaust port 46 by the exhaust fan 66, passes through the local exhaust duct 46, and is exhausted to the outside via the second exhaust duct 41. Therefore, a large amount of odor-laden air is quickly exhausted from the local exhaust duct 46 through the communication port 47 by the exhaust fan 6θ without any resistance because it does not pass through the total heat exchanger 30. 30 is exhausted regardless, total heat exchanger 3
There is no odor or steam attached to the 0.

Effects of the Invention As is clear from the description of the above embodiments, the present invention has a main body in which a heat exchange chamber and a blower chamber are partitioned by a partition plate, and an exhaust flow path is formed by an exhaust fan provided in the blower chamber. and a damper that opens and closes at a position between the partition plate opening in the exhaust flow path and the communication port of the local exhaust duct,
For normal intake/exhaust operation, leave the damper open at the partition plate opening, and when using the toilet room, open the communication port,
Since the opening of the partition plate is closed, the exhaust air bypasses the total heat exchanger, so that odor does not adhere to the total heat exchanger, and when connected to the kitchen room, there is no steam This method has the advantage that it does not adhere to the total heat exchanger and reduce the heat exchange efficiency, and that a large amount of exhaust can be performed locally and quickly.
