摘要： PROBLEM TO BE SOLVED: To suppress the sizes of banks on case sides abutted on a lip seal of a rotary door and to increase opening area of an air duct to be opened/closed by the rotary door. SOLUTION: A substantially U-shaped lip seal 10 fixed to both rotating tips of a door substrate 9 constituting a rotary door 8 is arranged by being offset at the outside of a surface (reference to A) passing a door rotary shaft 11. As a result, a seal surface is capable of reducing case side banks on both sides. By providing the banks in parallel to the lip seal 10, shut amount of the lip seal 10 (bending amount of the lip seal 10 at the time of abutting the banks) can be properly kept from the door rotary shaft 11 side to an outer periphery.

摘要： PROBLEM TO BE SOLVED: To accurately detect the clogging of a filter by detecting the clogging of the filter based on the change in resonance frequency which is an eigen value of the filter. SOLUTION: A fitting part 17c for fitting an ultrasonic generator 30 is integrally formed in the inside of a frame body 17a of a filter 17. When dust stuck to the filter 17, the weight (m) of the filter is increased. On the other hand, the resonance frequency of the filter 17 is expressed by an equation f=1/2π(k/m) . However, (k) is a constant in the equation. Therefore, if the weight (m) of the filter 17 is changed, the resonance frequency (f) is also changed. The ultrasonic generator 30 is applied to detect the change in the resonance frequency (f) and the changes in the input or the output voltage of the ultrasonic generator 30 caused by the deviation of the oscillation characteristics are detected so that the clogging of the filter part, 17b is detected. This constitution can accurately detect the clogging of the filter 17.

摘要： PROBLEM TO BE SOLVED: To make an in-cabin ventilating function and an outside air deodorizing function by outside air introduction compatible with avoidance of reducing the air amount of an air conditioner caused by the high-pressure loss of a deodorizing filter. SOLUTION: A deodorizing filter 25 for adsorbing malodorous components in the air is disposed in the air downstream (inner periphery side) of the circumferential wall 14a of an inside/outside air switching rotary door 14 for opening and closing an outside air introduction opening 18 and an inside air introduction opening 19 through a clearance with a prescribed interval L from the circumferential wall 14a, and the deodorizing filter 25 is formed so as to rotate integrally with the rotary door 14. When the inside/outside air switching rotary door 14 is displaced at an intermediate opening position which the circumferential wall 14a opens both of the outside air introduction opening 18 and the inside air introduction opening 19 at an intermediate opening, inside air flow running directly from the inside air introduction opening 19 to the outlet side of an inside and outside air switching box 13, and outside air flow running from the outside air introduction opening 18 through the clearance 24 and passing through the deodorization filter 25 to the outlet side of the inside/outside air switching box 13 are formed.

摘要： PROBLEM TO BE SOLVED: To reduce the generation of noise at a high pressure loss ventilation system and to increase a blowing capacity in a centrifugal blower by increasing an opening area so that the opening outer peripheral edge part of a suction port is positioned nearer the radial external side than the inside diameter edge of a fan. SOLUTION: A centrifugal blower is formed such that a number of auxiliary blades 80 are arranged at a portion corresponding to the blade 71 of a suction port 76 and the rotation direction component of a centrifugal type multiblade fan 72 is exerted on air flowing in from a portion, where the auxiliary blades 80 are arranged, by the auxiliary blades 80. This constitution performs smooth delivery of auxiliary flow air from the auxiliary blade 80 to a blade 71, whereby a flow rate of auxiliary flow air is increased and the generation of noise is reduced.

摘要： PROBLEM TO BE SOLVED: To reduce a noise by preventing disturbance of a sucked air in a unit adopting a rotary door for internal and external air switching unit. SOLUTION: A dimension L from a position corresponding to a rotation shaft 121b, i.e., a wall part 121f positioned near a suction port 104 of an inner wall of rotary door 121 to the suction port 104 is made to 20 mm or more. Thereby, since an air circulating near a wall surface of the rotary door 121 can inhibit a large variation of flow speed (air flow state) caused by a friction with the wall surface, it can be inhibited that a flow speed (air flow state) of an air sucked to a suction port 104 is largely deviated and distributed and a noise caused by a disturbance of the sucked air can be reduced.
