Patent number: 7481703Abstract: An air conditioner includes an air conditioning case for defining an air passage through which air flows into a vehicle compartment, a functional member located in the air conditioning case for performing air conditioning of the vehicle compartment, an outside wall member arranged outside a side wall of the air conditioning case to form a clearance with the side wall, and a coupling part through which the outside wall member is integrated with the side wall. In this air conditioner, the outside wall member is located across approximately a projected line of a central line of the functional member extending in a longitudinal direction of the functional member, projected onto the side wall. Therefore, a vibration of the air conditioning case can be reduced, and a noise generation can be effectively restricted.Type: GrantFiled: June 26, 2006Date of Patent: January 27, 2009Assignee: Denso CorporationInventors: Yoshihiko Okumura, Shigeyoshi Nagaya, Toshihiko Muraki

Patent number: 7392663Abstract: A two layer type air conditioner for vehicles facilitates drainage of water induced into a blower through an outside air intake to a condensed water outlet and prevents backflow of water to the blower. A blower has an intake duct for inhaling inside air and outside air. A double suction type scroll case mounted on the intake duct is divided into two passages by a partition plate. A blower fan is rotatably mounted in the two passages. A motor turns the blower fan. A case for the air conditioner includes an evaporator for cooling the air blown from the blower and a condensed water outlet for draining condensed water generated from the evaporator. The case is divided into two passages corresponding to those of the scroll case. A drain drains water induced into the blower to the condensed water outlet.Type: GrantFiled: December 21, 2005Date of Patent: July 1, 2008Assignee: Halla Climate Control Corp.Inventors: Sung-Ho Kang, Yong-Eun Seo

Publication number: 20070270094Abstract: A film valve assembly for a heating, ventilation, and air conditioning system includes first and second rollers disposed rotatably on a frame, a film valve, and a driving mechanism. The driving mechanism includes a driving member, and a speed reduction gear unit disposed between the driving member and the first roller. The driving member is operable so as to activate the speed reduction gear unit, thereby rotating the first roller on the frame in a selected one of opposite first and second directions. The second roller is biased to rotate in the first direction. The film valve has two ends coupled respectively to the first and second rollers.Type: ApplicationFiled: May 19, 2006Publication date: November 22, 2007Inventor: Chun-Shung Liang

Patent number: 7285041Abstract: An air passage switching device includes a slide door slidable along first and second opening portions partitioned by a partition portion, a guide member for guiding the slide door, and a link mechanism for slidably moving the slide door along the guide member. The link mechanism includes a rotation shaft rotatably supported in a case, a link portion provided at one end portion of the slide door, and a link lever connected to the rotation shaft and the link portion. The link portion is rotatable around the rotation shaft only within a range of the second opening portion in a sliding direction, among the first and second opening portions. Furthermore, the slide door can be provided with a first seal portion for sealing a clearance with outer peripheral portions of the first and second opening portions, and a second seal portion for sealing a clearance with the partition portion.Type: GrantFiled: December 12, 2005Date of Patent: October 23, 2007Assignee: DENSO CorporationInventors: Takahiro Yoshida, Takashi Yamamoto
