The Automotive air conditioning system is generally inboard at one Front wall arranged between the interior of the motor vehicle and the Engine compartment is formed. The resulting condensation must therefore from the motor vehicle air conditioning in the environment of the motor vehicle be derived. The housing of the automotive air conditioning system For this purpose, it is provided with a drain neck. At the drain neck a hose is installed which serves to drain the condensation in derive the free or in the environment of the motor vehicle. Of the Hose generally passes the condensate through a hole in the body in the open air. In the assembly of the motor vehicle the hose disadvantageously requires space for stretching and further there is a risk of incorrect assembly or a Forgetting the assembly of the hose.

The motor vehicle air conditioner 1 is provided with a refrigerant evaporator for cooling the air, with a heat exchanger for heating the air and with a fan for circulating the air (not shown). A housing 3 the automobile air conditioner 1 with outer walls 5 is on the outer wall 5 below with an opening 18 Mistake. At the opening 18 is a neck 4 formed, which is the shape of a cylinder 17 having.

A device 2 for guiding the condensed water into the environment of the motor vehicle consists of a receiving device 7 and a drain channel 6 , The cradle 7 is as a funnel 8th or drip tray 9 trained and serves a hydraulic connection between the nozzle 4 and the drainage channel 6 manufacture. Located in the interior of the motor vehicle air conditioner 1 forming condensation collects thus on the inside of the outer wall 5 and flows through the opening 18 at the neck 4 vertically down into the funnel 8th , In the funnel 8th the condensation collects and flows from the funnel 8th into the drainage channel 6 , At the drainage channel 6 are two rings on the outside 20 between which there is a groove 19 formed. By means of the groove 19 can the device 2 in a hole 33 a body 21 a motor vehicle are attached. A section of the device 2 between the two rings 20 and the cradle 7 consists of an elastic and easily bendable material, ie it is a bending section 22 available. The drainage channel 6 directs the condensation through the hole 33 the body 21 of the motor vehicle in the open or in the environment of the motor vehicle (not shown). The cone-shaped funnel 8th consists of a wall 10 , which is inclined at least 17 ° relative to a horizontal plane, so that even with an inclined position of the motor vehicle or during acceleration or deceleration processes of the motor vehicle, the condensed water exclusively in the drainage channel 6 inflows and not over the funnel 8th out into the interior of the motor vehicle flows.

In 1 is a position of the automotive air conditioning system 1 shown in front of a mounted final state. The device 2 is already by means of the groove 19 in the hole 33 the body 21 fastened in the final position. For mounting the automotive air conditioning system 1 this will be in the drawing plane in

This is a right area of the top edge 23 positioned lower than a left portion of the top edge 23 , An axis 26 the cradle 7 is inclined relative to a vertical axis and the axis 26 of the drainage channel 6 is vertically aligned. The stub 4 and the case 3 the automobile air conditioner 1 Thus, during assembly, ie the movement from right to left in an area between the wall 10 the device 2 to be moved. In a further movement of the motor vehicle air conditioning 1 to the left is the case 3 from the top edge 23 contacted, so that the funnel 8th to the left in the 2 shown position on the bending section 22 pivoted. In 1 and 2 is due to the sectional view of the contact between the upper edge 23 and the housing 3 not shown. In 2 is the assembled final state of the automotive air conditioning system 1 and the device 2 shown. There is a distance between the upper edge in the mounted final state 23 and the housing 3 , In a modification of this, the upper edge 23 in the assembled final state also directly on the housing 3 abutment (not shown). The axis 26 the cradle 7 and the drainage channel 6 are aligned vertically in the assembled final state. The device 2 is made of plastic. The wall 10 the cradle 7 is stiff and the rest of the area, ie the bending section 22 , the drain channel 6 and the grooves 19 , are made of an elastic and bendable material.

In 3 and 4 Fig. 2 are two perspective views of the device 2 presented before the assembled final state. The top edge 23 is deeper in one area than in another area, so the neck 4 during installation between the wall 10 the device 2 can be moved.

In 5 is a second embodiment of the automotive air conditioning system 1 and the device 2 shown. The second embodiment differs from the first embodiment according to FIG 1 to 4 in that at the top 23 a tab 25 is arranged. The tab 25 is only in a section of the upper edge 23 trained for kinematics of the movement of the funnel 8th is required, ie that the contact between the housing 3 and the device 2 by means of the tab 25 he follows. Incidentally, the operation and the structure correspond to the first embodiment.

In 6 is a third embodiment of the automotive air conditioning system 1 and the device 2 shown. The third embodiment differs from the first embodiment according to FIG 1 to 4 in that on the housing 3 a housing rib 27 is available. Only at the shell rib 27 occurs the upper edge 23 in contact with the housing rib 27 so that the shape of the housing rib 27 the kinematics of the movement of the funnel 8th depending on the movement of the automotive air conditioning system 1 from left to right in the drawing bene in 5 determined during assembly. Incidentally, the operation and the structure correspond to the first embodiment.

In 7 is a fourth embodiment of the automotive air conditioning system 1 and the device 2 shown. The fourth embodiment differs from the first embodiment according to FIG 1 to 4 in that the wall 10 the cradle 7 in a section a convolution 28 and also the wall 10 made of an elastic and bendable material. During a movement of the motor vehicle air conditioner 1 from right to left in the drawing of 7 In an analogous manner to the first embodiment, the upper edge 23 pivoted. In doing so, the in 7 right area of the upper edge 23 down or under compression move something to the left by folding 28 partially pushed together and then released, ie the wall 10 with the convolution 28 "Pressed" and "stretched" is. Incidentally, the operation and the structure correspond to the first embodiment. After reaching the end position, the folding springs 28 back to your starting position. The edge 23 can be completely or partially on the case 3 issue.

In 8th is a fifth embodiment of the automotive air conditioning system 1 and the device 2 shown. The fifth embodiment differs from the first embodiment according to FIG 1 to 4 in that the receiving device 7 from an annular elastic member 29 is formed with large wall thickness. The component 29 is rotationally symmetrical by means of a groove 19 at the body 21 attached. A recess 30 serves to accommodate insulation 31 or a rug 32 who is the component 29 surrounds and the bodywork 21 in the area of the bore 33 covers. During assembly, the component is first 29 at the hole 33 attached and then the vehicle air conditioner 1 in the drawing plane of 8th moved from left to right. This is the upper edge 23 the cradle 7 or of the component 29 above a lower end 34 of the neck 4 , At the beginning of the movement lies the lower end 34 outside the funnel 8th , z. B. above the insulation 31 , So that the lower end 34 in the in 8th represented position within the funnel 8th can get from the nozzle 4 and partly from the case 3 the elastic component 29 deformed due to a contact applied force. The component 29 is with a deformation recess 12 provided, which the deformation of the component 29 at the top 23 supported down. After the neck 4 in the 8th has taken position shown takes the elastic member 29 restore the original shape. In this way, the automotive air conditioning system 1 to be assembled. In addition and not in the 8th can represent the component 29 circumferentially one or more annular grooves as Verformungsausnehmungen 12 in particular, above the level of insulation 31 or the carpet 32 are provided.

In 9 are in a sixth embodiment additions in the structural design of the device 2 shown. On the inside of the wall 10 the cradle 7 are annular ribs 13 arranged. Ribs 13 serve in strong acceleration or deceleration processes of the motor vehicle, a flowing condensation against the slope of the wall 10 to prevent. In the vertical direction between the housing 3 or the outer wall 5 the automobile air conditioner 1 and the top edge 23 as a funnel 8th trained cradle 7 there is a gap. The distance is about 4 mm. As a result, in a particularly advantageous manner, condensation water, which is on the outside of the outer wall 5 forms in the funnel 8th inflow, because the condensation on the outside of the outer wall 5 to the outside of the neck 4 stream and there at the end of the neck 4 in the funnel 8th can fall off. This is the outer wall 5 also at the bottom with a corresponding slope towards the neck 4 provided so that the entire on the outer wall 5 forming condensation to the neck 4 and thus in the funnel 8th can flow.

The distance between the funnel 8th or the ribs 13 and the neck 4 in the vertical direction is about 3 to 5 mm. In particular, in the longitudinal direction of the motor vehicle, ie in the x-direction, the distance is about 3 mm and in the transverse direction of the motor vehicle, ie in the y-direction of the motor vehicle, the distance about 5 mm. These distances in the x- and y-direction as well as in the vertical direction, ie in the z-direction, also serve to compensate for manufacturing tolerances during manufacture and thereby avoid direct contact even with minor tolerances.

The housing 3 the automobile air conditioner 1 , the funnel 8th and the hose or drainage channel 6 are made of plastic. Preferably, the hose is made 6 made of elastic plastic. The cradle 7 and the hose or drainage channel 6 may be two individual, interconnected components or formed in one piece. The hose is sufficiently long to keep the condensation outside in the body 21 to derive.

In 10 is a perspective view of a bottom of the automotive air conditioning system 1 is posed. At the bottom of the case 3 or the outer wall 5 is a drainage channel in the longitudinal direction of the motor vehicle or in the x direction 24 educated. The gutter 24 has a U-shaped cross section in the x direction. In the y-direction, ie in the transverse direction of the motor vehicle, has the gutter 24 over a slope, which towards the neck 4 is aligned. The stub 4 is thus at the lowest point of the gutter 24 arranged. In addition, there is another gutter 24 ' provided the condensation from another area of the housing 3 collects and over a slope, which towards the neck 4 aligned is derived. Condensation, located in the interior of the motor vehicle air conditioning 1 forms, thus accumulates on the inside of the housing 3 and flows to the gutter 24 and the neck 4 , At the end of the neck 4 is one as a drip nose 14 trained drop ring 15 available. The drip ring 15 It serves to control the condensed water and direct it into the drip tray 9 can flow in. Furthermore, on the inside of the nozzle 4 drain notches 16 formed, which are aligned in the flow direction of the water. In 10 is just a procedure score 16 visible, noticeable.

Overall, are considered with the automotive air conditioning system according to the invention 1 and the device 2 for conducting water and the method according to the Invention associated significant advantages. When installing the automotive air conditioning system 1 in the interior of the motor vehicle, ie on the front wall of the motor vehicle, eliminates the additional installation of a hose for conducting the condensate from the motor vehicle air conditioning 1 in the environment of the motor vehicle, after the vehicle air conditioner 1 has reached the assembled final state. As a result, the disadvantages associated with failure to mount or incorrectly mount the hose can be virtually eliminated because such mounting of the hose is no longer required, ie automatic docking of the automotive air conditioning system with respect to the discharge of condensed water is possible. In addition, the necessary space for the hose in the interior of the vehicle can be saved. In addition, the working conditions in the pre-assembly of the motor vehicle are improved because the hose is often to mount in poor or difficult to reach places.
