Problems solved by technology

However, in the above structure, if the half-inner valve abuts against the restricting member when the valve is opened vigorously, a collision sound will be generated.
In addition, in the above-mentioned configuration, since it is necessary to make the restricting member protrude into the space in the housing, the shape of the housing becomes complicated.

Embodiment Construction

[0025] Hereinafter, a vehicle air conditioner according to an embodiment of the present invention will be described with reference to the drawings. In the drawings, the scale of each component is appropriately changed in order to make each component a recognizable size.

[0026] Figure 1A It is a sectional view showing a schematic configuration of a vehicle air conditioner S according to an embodiment of the present invention. The vehicle air conditioner S includes a blower unit Sa, a cooling unit (not shown), a heating unit (not shown), and the like. Figure 1A is a cross-sectional view of the blower unit Sa. The vehicle air conditioner S of the present embodiment is characterized by the blower unit Sa. Therefore, the blower unit Sa will be mainly described below.

[0027] The blower unit Sa is installed so that the outside air inlet 4 described later is on the upper side when the vehicle air conditioner S is mounted on the inside of the dashboard at the front of the vehic...

Abstract

The present invention provides an air conditioner for a vehicle. The air conditioner for a vehicle is provided with: an internal and external air switching device having a casing and an internal and external air switching door; a blower configured to create a negative pressure in the casing; and a semi-internal air conditioner. The air inlet is configured to introduce internal air into the casing when there is a negative pressure in the casing; the half internal air valve is arranged to block the half internal air inlet; the fixing part, It fixes the upper edge of the half inner valve to the inner wall surface of the housing. The distance from the lower end edge of the half inner valve to the fixed portion is uneven in the extending direction of the upper edge of the half inner valve.

Description

technical field [0001] The present invention relates to a vehicle air conditioner. Background technique [0002] Generally, the vehicle air conditioner is mounted on the front inside the vehicle. The vehicle air conditioner is configured such that the evaporator dehumidifies and cools the air blown by the blower fan. When an air-mixing system is used as a vehicle air conditioner, part or all of the air that has passed through the evaporator is sent to the heater core to be heated through the air mixing valve, and then mixed with the remaining air to generate conditioned air at a predetermined temperature. The generated conditioned air is supplied to each air outlet in the vehicle. [0003] The vehicle air conditioner has an inside and outside air switching device. The air supplied to the blower fan is selected from the inside air or the outside air through the inside and outside air switching device. The inside-outside air switching device has an inside-air inlet, an out...
