Abstract: In an automotive air conditioner, there is provided an air guide arrangement for achieving an effective mixing between cooled air from an evaporator and warmed air from a heater under a bi-level mode. The air guide arrangement is placed in the vicinity of an outlet opening of a warmed air passage extending from the heater. The air guide arrangement forces a warmed air from the outlet opening of the warmed air passage to effectively mix with a cooled air which flows in a direction from the evaporator toward a ventilation air outlet opening.

Abstract: A casing defines therein an air intake opening, an evaporator chamber, a full-passage, a bypass-passage and an air-mix chamber. A housing having a downwardly curved upper wall is incorporated with the casing to cover the air-mix chamber. An air blow is provided which forces air to enter the evaporator chamber from the air intake opening. An air-mix door is movably installed in the casing to selectively open and close the full-passage and the bypass-passage. An evaporator is installed in the evaporator chamber, and a heater core is installed in the full-passage. The downwardly curved upper wall is formed with first, second and third openings which are communicated with given portions of a passenger room of the vehicle respectively. A slide door assembly is mounted below the downwardly curved upper wall. The slide door assembly includes two slide doors which are arranged to vary the open area of the first, second and third openings in cooperation with each other.

Abstract: A heater unit of automotive air conditioning device comprises a case. In the case, there are defined a cool air passage, a hot air passage and an air mix chamber. The cool air passage has an upstream end merged with an air inlet opening of the case and a downstream end merged with the air mix chamber. The hot air passage has an upstream end merged with the upstream end of the cool air passage and a downstream largest area merged with the air mix chamber. The air mix chamber is directly communicated with air outlet openings of the case. A heater core is arranged in the upstream end of the hot air passage. An air mix door is pivotally arranged in the case to vary the flow rate between air directed toward the hot air passage and air directed toward the cool air passage. A shutter door is pivotally arranged in the downstream largest area of the hot air passage. A link mechanism is used for achieving synchronized pivoting movements of the air mix door and the shutter door.

Abstract: An air induction device for use in a motor vehicle. The vehicle has first and second air passages through which outside air and inside air pass respectively. The air induction device comprises a casing in which a motor-driven blower fan is installed. The casing has upper and lower portions. The upper portion has at least two openings which are respectively connected to the first and second air passages and selectively closed and opened by a door structure. The lower portion includes a bottom wall portion and two inclined side wall portions which are raised from a periphery of the bottom wall portion. An outlet passage conveys air from the interior of the casing to a remote position. The two inclined side wall portions are formed with respective lower inlet openings which are connected to the second air passage and selectively closed and opened by respective pivot doors. Each door is arranged to pivot outside the casing.

Abstract: A sensor holder for holding a temperature sensor is disclosed, which comprises a first part having a first passage formed therethrough and a second part having a second passage formed therethrough. The first and second parts are so united as to coaxially connect the first and second passages thereby to constitute an elongate passage through which air flows in a direction from the first passage to the second passage. The temperature sensor is located at a given position in the first passage. A heat insulating air cavity is provided by the first part near the temperature sensor.
