Description

  The present invention relates to a ventilation device for ventilating a room, and more particularly to a ventilation device capable of improving the airtightness and ventilation while improving the airtightness easily and accurately.

  Conventionally, to prevent negative pressure inside the house, to prevent mold and mite breeding, and to prevent indoor sickness caused by volatile organic compounds emitted from furniture, building materials, etc. A ventilation device is provided that ventilates the outdoor (outdoor) and indoors by communicating with each other through the outer wall. This ventilator generally has a cylindrical main body provided with a vent hole in a state of penetrating the outer wall, and is provided with covers for preventing insects and small animals from entering at both ends of the cylindrical main body. The one with a simple structure is used. However, some of them have been developed that can adjust the air flow rate. To adjust the air flow rate, one of the two blades that overlap the indoor air vent of the cylindrical main body is hand-held. Some of them have a structure that is slid to block the vent hole.

  For example, in Patent Document 1, as one conventionally known, two overlapping ventilation fans are provided at the indoor ventilation opening, and one of the ventilation fans is swung by turning a knob protruding to the center of the ventilation fan with a finger. A venting device having a structure that adjusts the supply air flow rate by changing the opening area is disclosed (see paragraphs 0006 and 0007 of Patent Document 1).

  In Patent Document 2, a register cap having a size that closes an opening of a register body for introducing outside air is connected to the register body, and a cylindrical screw shaft fixed to the register cap and fixed to the register body. A hollow cylindrical bearing member, a screw shaft having a spiral groove, a spherical body in which the bearing member is fitted into the spiral groove, and a biasing device that biases the spherical body into the spiral groove (See paragraphs 0017 and 0018 of Patent Document 2). In the venting device disclosed in Patent Document 2, the opening area can be adjusted by rotating the register cap by hand to bring the register cap into close contact with or away from the register body.

  However, in the ventilation device disclosed in Patent Document 1, when the ventilation fan is swung to close the ventilation opening, it is difficult to ensure high airtightness in the room, and the effect of air conditioning in the room is impaired. In addition, the venting device disclosed in Patent Document 1 has a structure in which even if the ventilating fan is swung to open the ventilating opening to the maximum, the opening area is only about half of the ventilator cross-sectional area, and the ventilation amount is sufficiently secured. It was difficult to do. Furthermore, since the ventilator disclosed in Patent Document 1 manually opens and closes the ventilation port, the opening rate of the ventilation port cannot be adjusted accurately, making it difficult to adjust the ventilation rate.

  Further, in the ventilation device disclosed in Patent Document 2, since the indoor ventilation port cover has a structure facing the ventilation hole, it becomes a hindrance when taking outside air into the room, and it is difficult to ensure a sufficient ventilation amount. Met. Moreover, also about the ventilator disclosed in Patent Document 2, as with the ventilator disclosed in Patent Document 1, the ventilation port is manually opened and closed, so the opening ratio of the ventilator cannot be adjusted accurately, It was difficult to adjust the air flow.
