JP 2003-105880 A JP 2003-185186 A

  In modern building windows, glass shingles are doubled and a hollow layer (air layer) is provided between them, and this hollow layer is used as a heat insulating layer so that the temperature inside the building is not affected by the temperature change of the outside air. Attempts have been made to reduce energy consumption for maintaining the temperature in the building.

  By the way, since the hollow layer is normally sealed, for example, during the daytime in summer, the temperature of the air in the hollow layer rises significantly due to irradiation of the double glass shoji of sunlight, and the air in the hollow layer is removed. There is a possibility that the temperature is higher than the temperature, and the load on the cooling in the building is increased, so that the energy consumption cannot be expected to be reduced.

  In recent high-rise buildings, the windows cannot be opened or closed to prevent dangers. It is necessary to do this, and the energy consumption due to this is enormous. Moreover, since such air conditioning circulates air in a building, an undesirable situation may occur if the air is once contaminated with bacteria or the like. is there.

  The above problem can also occur when a building wall is a double wall and a hollow layer is provided between the double walls.

  A ventilation direction control device that can realize energy saving and can preferably solve the above-mentioned problem is proposed in Patent Document 2. However, in such a ventilation direction control device, as long as it is described in Patent Document 2, a passage forming portion is provided. Since the electric motor that rotates the motor is attached to the side of the passage forming portion, it is difficult to install compactly because the electric motor is obstructive regardless of whether it is installed on the ceiling side or the floor side. Become. The same applies to the ventilation structure proposed by Patent Document 1.

In addition, while the openings 53 and 54 are not in communication, the passage forming portions 87, 88 and 89 of the ventilation direction control device 2 are brought into contact with the ridges 72, 73 and 74 via the seal member 90, respectively. The outside building 13 can communicate with the room 10 through the opening 37, the opening 14, the lower outer passage 15, the opening 53, the opening 52, the lower inner passage 12 and the opening 11, while the outside through the openings 14 and 21. 3 and the hollow layer 8, the room 10 and the hollow layer 8 through the openings 11 and 21, and the outside of the building 13 through the openings 19 and 17 and the air conditioner, heat exchanger or blower through the openings 19 and 23. The outside of the building 13 and the hollow layer 8 and the hollow layer 8 through the openings 23 and 17 and the air conditioner, the heat exchanger or the blower can be disconnected from each other. 10 or the air in the room 10 can be discharged to the outside air, and the room 10 can be cleaned with fresh outside air.

  As described above, according to the ventilation direction control device 1 or 2, the rotating means for rotating the passage forming portions 87, 88 and 89 inside the housing 85 in which the passage forming portions 87, 88 and 89 are provided on the outer surface 86. 58 tubular motors 101 are accommodated, so that the tubular motor 101 of the rotating means 58 does not protrude from the path forming portions 87, 88 and 89 and is not obstructed. Can also be installed compactly.

  The above is an example in which the ventilation direction control device 1 is arranged on the lower frame 9 and the ventilation direction control device 2 is arranged on the upper frame 16. Instead, this is arranged on either the lower frame 9 or the upper frame 16. In the above example, the space between the double window shojis 7 is used as the hollow layer 8, but instead, the hollow layer 8 is configured using the space between the double walls of the building wall. In this case, the lower wall 9 may be a lower wall disposed at the lower part of the double wall, and the upper frame 16 may be an upper wall disposed at the upper part of the double wall. The hollow layer 8 may be formed using a curtain instead of the glass shoji 6.

  Further, the control mode of the ventilation direction control devices 1 and 2 in the present invention is not limited to the above example. For example, the outside of the building 13 is the opening 37, the opening 14, the lower outer passage 15, the opening 53, the opening 52, the lower inner. At the same time as communicating with the room 10 via the passage 12 and the opening 11, the outside of the building 13 is opened through the opening 40, opening 19, upper outer passage 20, opening 53, opening 52, upper inner passage 18 and opening 17, and the air conditioner and heat exchange. The openings 52 and 53, the openings 52 and 54, and the openings 53 and 54 of the ventilation direction control device 1 may be disconnected from each other, and at the same time, the outside 13 of the building 13 may be connected to the openings 40 and 19. The upper outer passage 20, the opening 53, the opening 52, the upper inner passage 18, and the opening 17 may communicate with the air conditioner, the heat exchanger, or the blower, and further the opening 5. May be either a 53 or 54 so as to ensure the communication in the half-open.
