In an air duct selector, a supporting member has a grid shape, and is formed with four penetration holes. Since a film member is affixed to two fitting portions which are arranged on two ends of the supporting member, the film member is fixed on the supporting member. The supporting member and the film member are arranged in a duct to move in a vertical direction. When air flow is blown against the inside surface of the film member through the penetration holes 24a.about.24d, the film member is bent to swell against the film member, and presses against a peripheral portion of a cool air bypass opening portion to entirely cover the cool air bypass opening portion.

Air duct selector

According to the present invention, in an automotive air conditioner system, a link mechanism is provided by using a cool air passage provided in parallel with a warm air passage and a cool air/heated air mixing chamber provided at a downstream side of the warm air passage and the cool air passage. The clearance between a sliding door and a cooler can be set to a minimum distance as required. Further, it is not necessary to ensure a space for installing the link mechanism outside the case of the air conditioner. As a result, the size of the air conditioning unit including the sliding door can be effectively reduced.

Air conditioner for an automobile

An automotive air conditioner includes a casing, a rotary shaft rotatably supported in the casing, a rotary door connected to the rotary shaft and formed in a substantially arcuate shape, and drive means for rotating the rotary shaft. The rotary door includes a first opening defined by circumferential open ends, and a second opening defined by an arcuate circumferential wall. The casing includes a third opening, a fourth opening, and a fifth opening formed in a downstream end thereof and contiguously arranged along a circumferential surface of the rotary door. Opening areas of the third, fourth and fifth openings are adjusted by the rotary door. When the rotary door is rotated in a direction from the fifth opening toward the third opening and in a predetermined rotated position where one of the circumferential ends of the circumferential wall located at a rear end of the rotary door passes at least part of the fifth opening and opens the fifth opening, an air flows into the second opening and is directed toward the fifth opening through the first opening.

Air duct selector and automotive air conditioner

An air duct has air passages for the air to flow from the inside to the outside. An air passage switching device includes a rotary door and a film member for opening/closing and switching the air passages. The rotary door is formed with openings in its circumferential wall having an arcuate shape. The film member having ventilation holes to lap one of the openings is mounted with a slight slackness on the outer circumference of the rotary door. When this rotary door is rotationally displaced by a control cable, the air passages lapping the ventilation holes are opened, whereas the remaining air passages are closely sealed up by the film member which is expanded by a wind pressure.
