Description

The present invention relates to a composite ventilation unit provided in an outside air intake portion of a wall surface in a building or the like.

    The simplest method used to ventilate is a natural ventilation method that opens and closes windows and shojis to replace room air and outside air. However, windows in high-rise buildings are stronger than the ground. For this reason, there are many cases where the windows cannot be opened and closed, and most of them adopt a centralized system using building air conditioning. However, in recent years, there has been an eco-boom, and various measures have been taken to introduce natural ventilation methods in building air conditioning. A ventilation tunnel is provided on the outer wall of the building to provide communication between the inside and outside of the building. There have been provided a natural ventilation unit (see Patent Document 1) provided with a regulating valve, a device for ventilating a room using the eyes (see Patent Document 2), and the like.

Between the two flanges, there is a large blade whose surface is approximately the same diameter as the cylindrical inner diameter and a small blade on the side of the symmetrical position with respect to the axis. A rotating drum is formed, and the large blade of this rotating drum closes the two openings of the internal air intake duct and the indoor communication duct at the same time, and at other times opens one of the internal air intake duct and the indoor communication duct. The small blade can block the opening on the symmetrical position only when the large blade closes one opening of the inside air intake duct or the indoor communication duct. When either one reaches at least the opening of the outside air communication duct and stops, this opening is configured to maintain water tightness, and the air flow causes the outside air to flow out indoors through the air conditioning equipment; There are three types of air flow control: one that causes the outside air to flow out through the indoor communication duct and the other that causes the inside air to flow out again through the air conditioning equipment. A rotary ventilation unit characterized in that a sealing member is provided at the periphery of the air flow chamber side opening of the air flow chamber inlet of the outside air communication duct, and the rotary drum The rotary ventilation unit is characterized in that when the large blades or small blades reach the sealing member at the periphery of the opening, the sealing member is pressed to seal the opening.

    The rotary type ventilation unit of the present invention is a natural ventilation that takes in outside air as it is by rotating a rotating drum composed of a combination of flanges, large blades and small blades, and sends the outside air through the air conditioning equipment to the room. Mechanical ventilation, mechanical ventilation to return the room air to the room after passing through the air conditioning facility, and one ventilation unit can select a variety of indoor air conditioning methods, and the airflow chamber has a horizontally long cylindrical shape. It has the advantage that the structure is simple because the inside is a rotary drum with blades, and the installation area can be made extremely small, and there is an effect that the cost can be reduced accordingly, especially when introducing outside air It is assumed that rain and wind will blow in due to wind and rain and wind pressure, so at least that part should be sealed with a sealing member. There is an effect that water-tight air-tightness is maintained.
