Problems solved by technology

[0004] However, with the above-described vehicle air conditioner, since the drive portion (ie, the drive source), the first link member, and the second link member are provided on the side surface of the casing, when the vehicle air conditioner is installed in the engine room of the vehicle, for example, Due to the limitation of the layout of the engine room, the driving source cannot be arranged near the switching door, and thus the driving force of the driving part is troublesome and difficult to be transmitted to the switching door through the first and second link members.

Embodiment Construction

[0024] exist figure 1 In , reference numeral 10 denotes a vehicle air conditioner according to an embodiment of the present invention.

[0025] Such as figure 1 and figure 2 As shown, the vehicle air conditioner 10 includes: a housing 12, which is composed of a plurality of corresponding air passages in the housing; an evaporator 14 disposed inside the housing 12 for cooling air; heater core 16; an air mixing damper (switching damper) 18 which exchanges heat with the air introduced into the inside of the housing 12 through the evaporator 14 and the heating core 16 and mixes cool air whose temperature has been adjusted in a predetermined mixing ratio and hot air to thereby generate mixed air; and a driving force transmission mechanism 22 that transmits the driving force of the driving source (drive portion) 20 provided on the side surface of the housing 12 to the air mixing damper 18 so that the air Mixing damper rotation displacement.

[0026] Furthermore, inside the hous...

Abstract

The invention provides a vehicular air conditioning apparatus. In the vehicular air conditioning apparatus (10), a driving force transmission mechanism (22) is provided, which causes a switching operation of an air mixing damper (18) disposed in a casing (12) to be performed under a driving action of a drive source (20). The driving force transmission mechanism (22) includes a first gear (44) installed on the drive source (20), a second gear (46) enmeshed with the first gear (44), and a damper shaft (50), which is enmeshed with the second gear (46) and with a rack member (32) of the air mixing damper (18). The second gear (46) is supported rotatably on a gear holder (48), while the gear holder (48) is installed on a side surface of the casing (12).

Description

technical field [0001] The present invention relates to a vehicle air conditioner having a control mechanism for operating a switching door that switches a flow state of a fluid passage through which air is introduced from the outside or inside of a vehicle. Background technique [0002] Heretofore, in vehicle air-conditioning systems installed in passenger vehicles, internal and external air is sucked into the housing by means of a blower fan. The cold air cooled by the evaporator forming the cooling means and the hot air heated by the heater core forming the heating means are mixed in a desired mixing ratio inside the housing by adjusting the opening degree of the air mixing damper. Then, the mixed air is selectively blown out by opening and closing outlet doors of each outlet port respectively provided in the vehicle compartment, so as to adjust the temperature and humidity in the vehicle compartment. The air mixing damper and the outlet door include shafts which are axi...
