  • Patent number: 11745560
    Abstract: A blower unit includes a casing defining a first passage and a second passage, a first internal-external air switching member, a second internal-external air switching member, and a partition defining an opening. During a two-layer internal/external air mode, the first internal-external air switching member opens an external air inlet and closes an internal air inlet and the second internal-external air switching member closes the external air inlet and opens the internal inlet, so that the external air is directly introduced into the first passage through the external air inlet and the external air in the second passage is introduced into the first passage through the opening of the partition and the internal air is directly introduced into the second passage through the internal air inlet and the internal air in the first passage is introduced into the second passage through the opening of the partition.

  • Patent number: 9834065
    Abstract: In an interior air conditioning unit, a divided case is provided with a main water receiver, a main drain port, a side wall, a secondary drain port, a partition wall, a notch, a droplet reservoir, a path, and a tilted portion. The side wall, the secondary drain port, the notch, the droplet reservoir, the path, and the tilted portion are respectively located such that a condensate water flows out of the main water receiver and reaches the secondary drain port through the notch before a water surface of the condensate water reaches a fitting portion between the divided cases. According to the above-described configuration, the condensate water produced in the cooling heat exchanger can be certainly prevented from leaking through the fitting portion of the air conditioning case.

  • Patent number: 9776474
    Abstract: A water discharge device that collects and drains condensed water generated in an air conditioning device includes: a drainage path along which condensed water is able to be drained in a draining state in which condensed water is expelled; and an opening and closing member that is able to block and open the drainage path. The opening and closing member blocks the drainage path so as to limit movement of air due to dynamic pressure when in a non-draining state other than the draining state. The opening and closing member drains condensed water through the drainage path when in the draining state.

  • Patent number: 6918262
    Abstract: An air conditioning system includes an air conditioner for blowing conditioned air toward a compartment of a vehicle, and a dashboard having a design surface exposed to the compartment. An inner air passage extending nearly parallel to the design surface is formed in the dashboard, and a plurality of diffusion blowing openings are formed in the design surface. Thus, the condensed air is blown from the diffusion blowing openings into the compartment of the vehicle, while passing through the inner air passage. For example, cool air is blown from the diffusion blowing openings, so that the cool air can cool the dashboard while cooling the compartment of the vehicle. Moreover, because the cool air passes through the inner air passage extending nearly parallel to the design surface, the dashboard can be effectively cooled.

  • Patent number: 6877550
    Abstract: In a vehicle air conditioner, an evaporator is disposed at an upper side of a blower approximately horizontally so that air blown by the blower passes through the evaporator from below upwardly. The evaporator is slightly tilted from a horizontal surface by a predetermined angle, and the blower is disposed in such a manner that air is mainly blown by the blower toward the evaporator in a direction substantially parallel to a tangential line at a scroll finish portion of the scroll casing. Accordingly, condensed water on a bottom heat-exchanging surface of the evaporator can be pushed downwardly by component force of the flow of air mainly blown from the blower.

  • Patent number: 6758740
    Abstract: In an initial stage of a cool down operation of a vehicle air conditioner, a rapid cooling operation is performed while cool air is directly blown to a passenger from direct air outlets. In a later stage of the cool down operation of the vehicle air conditioner, a temperature of an inner wall portion of a passenger compartment is reduced while cool air is indirectly supplied to the passenger of the passenger compartment from the indirect air outlet. Accordingly, cool air can be locally blown to the passenger in the initial stage, and cool air can be supplied to the entire passenger compartment while restricting an adverse effect due to heat radiation of the inner wall portion in the later stage. Thus, operation performance of the air conditioner can be improved while comfortable air conditioning feeling can be given to the passenger in the passenger compartment.

  • Patent number: 6722970
    Abstract: In a vehicle air conditioner, a blower case for accommodating a blower is connected to an air conditioning case for accommodating an evaporator and the like by a connection duct made of a vibration-absorption material. Therefore, a vibration, transmitted from the blower case to the air conditioning case, can be effectively absorbed by the connection duct, thereby reducing the vibration transmitted from the air conditioning case to a steering wheel unit through a supporting member.

  • Patent number: 6705672
    Abstract: An air-conditioning duct structure is included in a vehicular dash beam member. Material for the duct is made of a heat insulating and sound absorbing material and is adhered onto the surface of a sheet material for the beam member which is then bent into a semi-tubular shape so that the material for the duct is positioned inside thereby forming beam member bodies. Beam member bodies are combined by joining their joining surfaces that face each other to thereby form a tubular closed sectional shape. Achieving vibration attenuation, noise absorption and the heat insulating functions with an inner surface sheet member of an air conditioning duct is achievable. An air conditioning duct extending across a vehicle's width is formed by joining a metal reinforcing member and a resin cover. The sheet member is put between the reinforcing member and the cover.
