Description

  The present invention relates to an air inlet that ventilates a room.

  Conventionally, this type of air intake is widely used as a natural air intake in a building room of a ventilation device that exhausts indoor air through a wall surface of a house. The opening of the intake port is manually performed, and the opening is adjusted according to changes in season and temperature. Also, ventilators that automatically open and close in response to changes in temperature are equipped with a coil spring made of a shape memory alloy with an automatic opening and closing function, and the aperture ratio automatically changes in response to changes in temperature. However, the opening state is determined by the air temperature, and the operation is not related to the interlocking with the ventilation device (for example, see Patent Document 1).

  Hereinafter, the intake port will be described with reference to FIG.

An intake frame 103 is installed in a cylindrical duct 102 that penetrates the indoor side and the outdoor side of the wall surface 101, and a rotary shaft 105 with open / close blades 104 attached to the upper and lower sides of the intake frame 103. The rotary shaft 105 has a shape memory alloy coil spring 106 that opens and closes the open / close blade 104 according to the ambient temperature, and an open / close blade 104 that is manually connected to the upper portion of the open / close blade 104 and moves the open / close knob left and right. Thus, the open / close blade 104 can be manually opened and closed.
