  • Patent number: 6796368
    Abstract: In an air conditioning apparatus where air flows through a cooling heat exchanger (21) upwardly from below, it is an object to improve draining performance of condensed water in the cooling heat exchanger (21). To achieve this object, the cooling heat changer (21) for cooling air is disposed in a case (20) forming an air passage to be inclined by a small angle (&thgr;) from a horizontal direction, the inclination direction of the cooling heat exchanger (21) is the same direction as a longitudinal direction (B) of tubes (21a) through which cooling fluid flows, and the cooling heat exchanger (21) is disposed so that a flow direction (A) of air flowing into a lower side of the cooling heat exchanger (21) is perpendicular to the longitudinal direction (B) of the tubes (21a).

  • Patent number: 6070425
    Abstract: In an air conditioning apparatus, an evaporator is disposed in an air-conditioning case to be inclined relative to a horizontal direction and to form a lower space below the evaporator. Air flows through the evaporator from a lower side toward an upper side thereof in the air-conditioning case. The lower space is partitioned by a partition member into an air-blown space and a drain space, and a drain guide member is disposed in the drain space to approximately contact a lower end portion of the inclined evaporator, where condensed water is gathered. Therefore, it can prevent air from hitting from below against the lower end portion of the evaporator. Consequently, the condensed water that has been gathered at the lower end portion of the inclined evaporator can be discharged rapidly along the drain guide member without being affected by the flow of air, and drips to a bottom surface of the air-conditioning case.

  • Patent number: 6019163
    Abstract: An air conditioning apparatus for a vehicle includes an evaporator and a heater core disposed approximately horizontally. In the air conditioning apparatus, an air-mixing door for adjusting a flow ratio of air passing through the heater core and air passing through a bypass passage is disposed, and air guide plates for guiding air are formed on a surface of the air-mixing door, positioned at a side of the bypass passage. A blower is disposed so that air is blown in an air-blowing direction approximately horizontally, and thereafter flows upwardly toward the heater core. The air guide plates guide air from a forward side toward a backward side of the air-blowing direction. Thus, in the air conditioning apparatus, a flow distribution and a temperature distribution of air to be blown toward the passenger compartment can be made uniform.

  • Patent number: 6019162
    Abstract: An air conditioning apparatus for a vehicle includes a blower case for accommodating a blower, an air conditioning case for accommodating an evaporator and a heater core, and a middle duct detachably connected to both the blower case and the air conditioning case. The air conditioning case is disposed at a side of the blower case to form a space having a predetermined distance therebetween, the evaporator is disposed in the air conditioning case approximately horizontally, and the heater core is disposed approximately horizontally at an upper side of the evaporator. Further, a receiving portion for supporting the evaporator is formed on an inner surface of the middle duct. In the air conditioning apparatus, the evaporator can be taken out from the air conditioning case to the space between the air conditioning case and the blower case by the detachment of the middle duct from the blower case and the air conditioning case, while the blower case and the air conditioning case are installed in the vehicle.

  • Patent number: 5899262
    Abstract: 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.

  • Patent number: 5701949
    Abstract: 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.

  • Patent number: 5699851
    Abstract: According to the present invention, a sliding door is positioned between the cooler and the heater and slidable in a direction crossing both the cool air passage and the warm air to control each amount of air flowing to the warm air passage and air flowing to the cool air passage, and the sliding door slides vertically in such a manner that an upper portion of the sliding door inclines toward the cooler. Since the sliding door slides itself in the vertical direction, with the upper portion of the sliding door inclined to the cooler, condensed water, which is likely to move with the blown air from the cooling unit to the air downstream side, can be smoothly guided downwardly with the air flow along the inclination of the sliding door, thus preventing the stench caused by mold and corrosion of the heater.
