Embodiment Construction

[0017] Next, an air conditioner according to one embodiment of the present invention will be described with reference to the drawings.

[0018] Such as figure 1 As shown, the air conditioner 1 of this embodiment is housed in the instrument panel IP at the front of the vehicle interior 2 . That is, the air conditioner 1 is accommodated between the dash panel DP and the instrument panel IP of the vehicle. The air conditioner 1 includes a blower unit 4 and an air conditioner unit 5 .

[0019] Such as Figure 5 As shown, the air supply unit 4 includes: a housing 8, which has: two vortex chambers 6, 7 with the same vortex centerline; a pair of fans (so-called twin fans (twinfan)) 9, 10, which are respectively accommodated In each vortex chamber 6 , 7 ; an electric motor 12 for driving these fans 9 , 10 . Fans 9 and 10 are multi-blade centrifugal fans. The motor 12 is arranged between the two fans 9 , 10 . The drive shaft 11 of the motor 12 serves as the rotation shaft of the...

Abstract

An air conditioner (1) has a fan unit (4) and an air conditioning unit (5). The fan unit (4) has fan cases (9, 10) that define a pair of independent scroll chambers (6, 7) and a pair of fans (9, 10) that are individually arranged in the pair of scroll chambers (6, 7). The air conditioning unit (5) has an air conditioner case (13) that defines an airflow path (P) in which air from the fan unit (4) is allowed to flow and also has air conditioning components (14, 15, 17) that are arranged in the airflow path (P) and through which the air from the fan unit (4) is caused to pass to perform air conditioning. The air conditioner has a partition section (25) for partitioning that portion (P1) of the airflow path (P) which is from an inlet (PO) up to the air conditioning component (14) on the uppermost stream section. The portion (P1) is partitioned into a pair of independent paths (P1a, P1b). The pair of independent paths (P1a, P1b) is connected to exits (6b, 7b) of the pair of scroll chambers, respectively.

Description

technical field [0001] The present invention relates to an air conditioner such as a vehicle air conditioner including an air conditioner and a blower unit having a pair of fans. Background technique [0002] As a prior art of such an air conditioner, there is, for example, a vehicle air conditioner disclosed in JP-A-5-172100. Such as Figure 10 As shown, this vehicle air conditioner includes an air blower unit 101 and an air conditioner unit (not shown) that air-conditions the air sent from the air blower unit 101 . The blower unit 101 has: a casing (casing) 104, which has two vortex chambers 102, 103 juxtaposed with the vortex centers overlapping; a pair of fans 105, 106, which are accommodated in each vortex chamber 102, 103; 107, which is used to drive these fans 105,106. When the motor 107 is driven, the pair of fans 105 and 106 rotate. Then, air is sucked into the scroll chambers 102 , 103 from the suction ports 108 , 109 . The air sucked into the scroll chambers 1...
