Problems solved by technology

[0007] However, if the air volume switching device with such a structure is arranged coaxially with the air blowing direction of the duct, in order to diffuse the air, openings 105, 106 must be provided on the side of the cylindrical member 101, and along with the openings 105, 106 setting, it is also necessary to provide air passages, thereby making the outer diameter of the air volume switching device larger than the outer diameter of the duct
If the size of the air volume switching device is increased, a new space is required in the width direction near the air outlet, and it is difficult to arrange the air volume switching device when the arrangement space is restricted.

Abstract

The invention aims to provide a vehicle air-conditioning device which has an air quantity switching device with a compact structure, wherein the air quantity switching device (13) adopts the following structure that: the hollow physical form of the device consists of a first truncated cone part, a second truncated cone part and a third truncated cone part (50, 40, 30) which are truncated cone-shaped and are overlapped; the upper surfaces and the lower surfaces of the truncated cone parts (50, 40, 30) are provided with upper opening parts (54, 44, 34) and lower opening parts (59, 49, 39), while the inclined planes (55, 45, 35) are provided with inclined opening parts (56, 46, 36); two arm parts (21, 21) are erected at the lower part of the first truncated cone part (50) and are provided with an air quantity adjusting disc (22); moreover, a steering unit (15) is embedded in the upper part of the air quantity adjusting disc (22).

Description

technical field [0001] The present invention relates to an air conditioner, which has an air volume switching device. The air volume switching device is arranged near an air outlet of the air conditioner and adjusts the air volume. Background technique [0002] Conventionally, there has been known an air conditioner for vehicles such as buses, in which an air volume switching device is provided at the air conditioning duct to adjust the air volume (Japanese Patent Laying-Open No. 2001-191790 ( Figure 10 ), hereinafter referred to as the patent offering 1). [0003] The following combination Figure 12 Patent Document 1 will be described. [0004] Figure 12 It is an explanatory diagram of the basic structure of the prior art, wherein the air volume switching device 100 is configured such that an orifice 102 is provided at the lower part of the cylindrical member 101, and above the orifice 102 and inside the cylindrical member 101, Nozzle part 103 is installed and this no...
