Abstract

An air conditioning system includes an intake housing with a fresh air opening and a recirculation air opening, a filter housing to admit an air filter and a fan housing with a fan for intake by suction of air through the intake housing and directing the air through the filter housing. The fresh air opening and the recirculating air opening are aligned in a common horizontal direction and in a vertical direction one above the other. The recirculating air opening is situated in the gravitational direction beneath the fresh air opening. Between the fresh air opening and the recirculating air opening a separation area is configured, with drainage means in such a way that the fluid penetrating into the fresh air opening, when flowing over the drainage means is directed past the recirculating air opening in a receiving area placed below the recirculating air opening.

First claim

What is claimed is:

1. An air intake of an air conditioning system of a motor vehicle comprising:
an intake housing having a fresh air opening and a recirculating air opening formed therein, the recirculating air opening aligning with and formed beneath the fresh air opening with respect to a vertical direction of the air conditioning system, each of the fresh air opening and the recirculating air opening configured for receiving air to be brought into the air conditioning system therethrough;
a filter housing in fluid communication with and disposed downstream from the intake housing with respect to a direction of a flow of the air through the air conditioning system, the filter housing configured to receive an air filter;
a fan housing in fluid communication with and disposed downstream from the filter housing with respect to the direction of the flow of the air through the air conditioning system, the fan housing having a fan configured to convey the air through the intake housing and the filter housing;
a separation area formed intermediate the fresh air opening and the recirculating air opening and having a drainage component disposed therein, the drainage component receiving a fluid from the fresh air opening and directing the fluid past the recirculating air opening; and
a receiving area formed on an underside of the intake housing and an underside of the filter housing, the receiving area disposed beneath the recirculating air opening with respect to a vertical direction of the air conditioning system, wherein the filter housing includes a closing element disposed thereon, the closing element selectively opening and closing the filter housing for inserting and removing the air filter with respect to the filter housing, and wherein the receiving area is integral with the closing element.

2. The air intake of claim 1 , wherein the receiving area collects the fluid from the drainage component, the receiving area having an opening formed therein configured to drain the fluid therefrom.

3. The air intake of claim 1 , wherein the receiving area is pan-shaped.

4. The air intake of claim 1 , wherein the receiving area is in fluid communication with a drainage system of the air conditioning system.

5. The air intake of claim 1 , wherein the closing element is pan-shaped.

6. The air intake of claim 1 , wherein the closing element includes a bottom and a wall extending vertically from the bottom with respect to the vertical direction of the air conditioning system, the wall terminating in an edge.

7. The air intake of claim 6 , wherein the edge of the wall engages the filter housing to define a separating plane.

8. The air intake of claim 1 , wherein the drainage component includes a connection element depending at a bound end from the intake housing with respect to the vertical direction of the air conditioning system, extending into the recirculating air opening, and terminating in a drop-off edge.

9. The air intake of claim 8 , wherein the connection element extends horizontally along an upper side of the recirculating air opening with respect to a horizontal direction of the air conditioning system.
