Problems solved by technology

[0018] In the reel case 70 of the blower unit of the conventional vehicle air conditioner, the flow path of the upper reel case 83 and the flow path of the lower reel case 84 are different from each other in ventilation resistance. The starting point is formed to be the same, so there is a problem that the air-conditioning performance is lowered

Embodiment Construction

[0072] Next, the technical configuration of the blower unit of the vehicle air conditioner will be described in detail with reference to the drawings.

[0073] The double-deck vehicle air conditioner according to an embodiment of the present invention is a device that introduces external air into the room or circulates the indoor air and heats or cools the room so as to realize indoor heating or cooling. It consists of a blower unit that sends air and an air conditioning unit that adjusts the air sent from the blower unit and blows it out to the outside of the vehicle. The double-deck vehicle air conditioner is configured to separately send the inside air and the outside air, thereby maintaining high heating performance while ensuring defogging performance during heating.

[0074] Figure 7 is a sectional view showing an air conditioning unit of a two-story vehicle air conditioner according to an embodiment of the present invention. refer to Figure 7 , The air-conditioning...

Abstract

The invention discloses a blower unit of an air conditioning device for a vehicle. The blower unit compensates and supplements different air resistances between an upper reel housing and a lower reelhousing and can improve air conditioning performance through up-and-down equal pressure adjustment. A blower unit of a vehicle air conditioning device is a blower unit of a double-layer vehicle air conditioning device that separately transmits internal air and external air, and includes: a first spool that is provided with a first blower wheel and in which a first air flow path is formed; and a second reel which is disposed below the first reel, is provided with a second blower wheel, and in which a second air flow path is formed, the diameter of the second blower wheel and the diameter of thefirst blower wheel being different from each other.

Description

technical field [0001] The present invention relates to a blower unit for a vehicle air conditioner, and more particularly, to a double-deck blower unit for a vehicle air conditioner capable of maintaining high heating performance while ensuring defogging performance during heating. Background technique [0002] In general, an air conditioner for a vehicle is a device that introduces outside air into the room or circulates the indoor air and heats or cools it to achieve indoor heating or cooling. Consists of an air-conditioning unit that sends air from the blower unit and blows it out to the outside of the vehicle. [0003] In particular, in heating, in order to maintain high heating performance while ensuring defogging performance, a two-layer (2-layer) air conditioner has been developed. When driving with heating in winter, the most effective way to remove frost that condenses on the windows is the cool, humid air, which can result in a drop in the interior temperature. ...
