  • Patent number: 7699096
    Abstract: The first cold air flow door 26 and the first hot air flow door 24 for adjusting the blowout air temperature are arranged in the first air passage, and the second cold air flow door 27 and the second hot air flow door 25 for adjusting the blowout air temperature are arranged in the second air passage. When a larger target air flow volume between the target air flow volume on the first air passage side and the target air flow volume on the second air passage side is selected so as to determine an air flow volume of the blower, in an air passage to which the smaller target air flow volume is applied, while the ratio of the cold air flow volume to the hot air flow volume is being maintained constant, the passage opening area is throttled by the cold air flow door and the hot air flow door.

  • Patent number: 7510165
    Abstract: A door decelerator system reduces or prevents undesirable limits of audible door noise in an HVAC unit. The system includes a door, movable between end or stop positions; and a kinematics lever connected to the door at a common axis of rotation or the kinematics lever having a deceleration axis common with the door, the kinematics lever having a deflection area incorporated therein. A rigid rib is incorporated in a housing of the HVAC unit, the rigid rib disposed in compressive contact with the deflection area at least as the kinematics lever reaches an end of travel. The deflection area is physically separable from the rigid rib.

  • Patent number: 7481703
    Abstract: 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.

  • Patent number: 7392663
    Abstract: 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.
