Blower unit, and method of manufacturing blower unit

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.

Air conditioning device for vehicle

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.

Water discharge device and air conditioning device with same

An upper opening portion () and lower opening portion () are arranged in a door body () located below a side window (), and an air conditioning unit () is arranged inside the door body (), and a rotary position of a scroll casing () of a blower () is selected so that air can flow from the lower opening portion () to the upper opening portion () at the time of air-cooling and air can flow from the upper opening portion () to the lower opening portion () at the time of heating.

Air conditioner for vehicle use

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.

Air conditioning system

A vehicle air conditioner is controlled to directly lower the temperature of the interior equipment before a driver enters a vehicle, using an airflow from an air outlet. The air outlet can be placed on and/or against the interior equipment. The interior equipment can be an instrument panel, a steering wheel or a seat.

Vehicle air conditioner

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.

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.

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.

Vehicle air conditioner and mounting structure

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.

Vehicular air-conditioning duct structure and forming method, and vehicular electric-wiring fixing structure

The same size casing is used for interior air blowers of a combination air conditioning and heater interior unit disposed in left- and right-hand drive vehicles, respectively. A casing width is made nearly constant from a start-of-winding position to an end-of-winding position. An approximately central fan datum line which passes through a fan is offset to a suction port side with respect to a casing datum line which passes through an approximately central part of a portion of the casing parallel to a blower rotational axis. A flange portion of a motor holder is located at a position offset to one side (suction port side) along the rotational axis rather than an opposite side along the same direction in the casing. By replacement of impression cores it is possible to manufacture the casings for right- and left-hand drive vehicles, respectively.

A wiring system of indication instrument for vehicle includes a transverse member disposed inside the indicating instrument to extend in a transverse direction of the vehicle, a wire-integrated cluster disposed inside the indication instrument and an electric distributor box disposed at an end of the transverse member. The cluster includes a bundle of main lead wires disposed to extend straight along said transverse member, and the distributor box distributes electric power and signals transmitted by the wire-integrated cluster.

Wiring system of indication instrument for vehicle

There is provided an air guide duct for a vehicle, the air guide duct connected for communication with an air conditioner unit provided in a passengers' room in a vehicle, the air guide duct adapted to pass and guide temperature regulated air supplied from the air conditioner unit, the air guide duct comprising a first base body constituting one duct half, the first base body including a mounting part for allowing a wire element of an electrical component system to be contained along the air guide duct, and a second base body constituting the other duct half, the second base body covered over the first base body to define an air flowing space therebetween, the second base body including a cover piece which laterally extends from the duct, wherein the mounting part containing the wire element is so constructed as to be covered with the cover piece.

Air guide duct for vehicle

A vehicle air conditioning apparatus includes a hot water valve for adjusting a flow amount of hot water flowing into a heating heat exchanger, a bypass passage through which air bypasses the heating heat exchanger, and a bypass door for opening and closing the bypass passage. In a high-temperature side area where temperature of air blown into the passenger compartment becomes higher, the temperature of air to be blown into the passenger compartment is adjusted by a hot-water flow adjustment of the hot water valve while the bypass door is operated at a fully closed position. On the other hand, in a low-temperature side area where temperature of air blown into the passenger compartment becomes lower, the temperature of air to be blown into the passenger compartment is adjusted by combining the hot-water flow adjustment of the hot water valve and the air flow adjustment of the bypass door. Thus, even in a minute flow area of hot water flowing into the heating heat exchanger, the temperature of air blown into the passenger compartment is accurately adjusted.
