As shown in fig. 1 and fig. 2, specifically, the air conditioner case drain pipe includes a pipe body 110, two ends of the pipe body 110 are provided with an inlet 1111 and an outlet, the inlet 1111 is communicated with an external structure (in this embodiment, the external structure is the air conditioner case 200, which will be described below as the air conditioner case 200), liquid in the air conditioner case 200 (in this embodiment, the liquid is condensed water when an evaporator in the air conditioner case 200 operates, but is not limited thereto, which will be described below as the condensed water) can enter the pipe body 110 from the inlet 1111 and flow out from the outlet, a drain hole 1112 is provided on an outer periphery of the pipe body 110 on a side facing the outlet, and the drain hole 1112 can drain the liquid.

Through the structure, the condensate water that the evaporimeter in the air-conditioning box 200 produced flows into pipeline body 110 by inlet 1111, flows out from the liquid outlet again, if there is insect or other impurity to block up the liquid outlet of pipeline body 110, the comdenstion water can flow out from wash port 1112, can not cause the condition that can't get rid of the condensate water in the air-conditioning box 200, and guaranteed the security of air-conditioning box 200 inner structure, and the condition that evaporimeter/filter core go mildy and foul in the air-conditioning box 200 can not appear, the freshness of the in-car environment has been guaranteed.

Optionally, above-mentioned inlet 1111 and air conditioning case 200 interference fit for there is not the clearance between inlet 1111 and the air conditioning case 200, has realized the leakproofness between drain pipe and the air conditioning case 200, has guaranteed that condensation hydroenergy flows to the car outside from the drain pipe, can not flow to the car in, avoids causing the damage of the inside device of car.

Referring to fig. 2, in the present embodiment, a certain distance is formed between the center of the drain hole 1112 and the liquid outlet, so that insects or impurities cannot block the drain hole 1112, and drainage of the drain hole 1112 is facilitated. Preferably, the distance between the center of the drain hole 1112 and the liquid outlet is A, and A is greater than or equal to 30mm and less than or equal to 40mm. Because the size of the insects or impurities that can get into the air-conditioning box 200 through the air outlet of the air-conditioning box 200 and get into the pipeline body 110 from the outlet of the drain pipe has certain limitations, the above distance a can ensure that the drain hole 1112 cannot be blocked, so that even if the outlet is blocked, the drain hole 1112 can still discharge the condensed water.

Preferably, the diameter of the drain hole 1112 is 5mm, which can meet the drainage requirement of the general air conditioning box 200. It is understood that the diameter and the distance a of the drainage holes 1112 can be adapted according to actual requirements, and are not limited in detail.

Furthermore, a plurality of drain holes 1112 are arranged on the outer circumferential surface of the pipeline body 110 at intervals, and the plurality of drain holes 1112 can make the drainage effect better, thereby avoiding the problem that condensed water cannot be drained due to the blockage of one drain hole 1112.

Preferably, the drain holes 1112 are provided in two, and the two drain holes 1112 are symmetrically provided along the axis of the duct body 110. The drainage effect of the air conditioner case 200 can be achieved by the two symmetrically arranged drainage holes 1112. In addition, the drain holes 1112 are symmetrically arranged, so that the manufacturing is convenient.

In this embodiment, as shown in fig. 1 and fig. 2, the duct body 110 is a bent structure, that is, the duct body 110 is formed by splicing a plurality of pipes 111, and the specific shape of the duct body can be adaptively adjusted according to the installation space in the automobile.

The design of above-mentioned duckbilled structure is in order to reduce the windward side, prevents that the car from going the in-process, thereby the not equidirectional and air current that differs in size of automobile body floor 300 below pours backward into the drain pipe and leads to the drainage not smooth, can improve the drainage effect of this drain pipe.

Alternatively, as shown in fig. 1 and fig. 2, the cross section of the water outlet member 112 is kidney-shaped (i.e. oval), and the outer diameter of the water outlet member 112 gradually decreases from the pipeline 111 to the liquid outlet, so as to effectively prevent the external air flow from affecting the drainage effect of the drainage pipe. Optionally, the length of the water outlet member 112 is 15mm, so that the distance a between the center of the water discharge hole 1112 and the liquid outlet is set to be 30mm-40mm, which can avoid the position blocked by insects, and further improve the drainage effect of the drainage pipe.

Further, as shown in fig. 1 and fig. 2, an abutting flange 1113 is provided at the middle portion of the pipe body 110, and the abutting flange 1113 can be connected to an external fixing member (in the present embodiment, the external fixing member is a vehicle body floor 300, and the vehicle body floor 300 is a sheet metal member, and the vehicle body floor 300 will be described below). The structure enables the drain pipe to be fixed and cannot shake along with the movement of the automobile, and therefore the stability of connection between the drain pipe and the air conditioning box 200 can be improved. And the sealing arrangement makes the interior of the vehicle body sealed with the outside, and prolongs the service life of other structures in the vehicle body.

Specifically, the abutting flange 1113 is an elastic structure, which has a certain elasticity; the one side that butt flange 1113 kept away from vehicle body floor 300 is the first face, and the one side that butt flange 1113 faces vehicle body floor 300 is the second face, and the external diameter of butt flange 1113 reduces to the second face by first face gradually, and through-hole 310 has been seted up to vehicle body floor 300, and the outer peripheral face of butt flange 1113 can butt in the pore wall of through-hole 310. That is, the second surface of the abutment flange 1113 abuts against the vehicle body floor 300, and then the second surface is inserted into the through hole 310 until the relative movement cannot be continued, so that the outer peripheral surface of the abutment flange 1113 can abut against the hole wall of the through hole 310, and the sealing between the two is realized.

As shown in fig. 3 and 4, the embodiment further provides an air conditioning assembly, which includes an air conditioning cabinet 200 and the air conditioning cabinet drain pipe, the air conditioning cabinet drain pipe is communicated with the air conditioning cabinet 200, so that condensed water in the air conditioning cabinet 200 can be discharged from the drain pipe, the hidden drainage trouble of the drain pipe can be eliminated, the drain pipe is prevented from being blocked, the drainage is good, the air conditioning cabinet 200 can be guaranteed to drain water smoothly, the safety of the air conditioning assembly is guaranteed, and the cost is low.

Specifically, the air-conditioning case 200 is provided with a water collection tank 210, the water collection tank 210 is used for collecting condensed water in the air-conditioning case 200, the water collection tank 210 is provided with a drainage pipe 220, the pipe body 110 is communicated with the drainage pipe 220, and the condensed water can flow into the pipe body 110 from the drainage pipe 220. That is, the liquid inlet 1111 of the pipe body 110 is in interference connection with the drain tube 220, so that the drain tube and the drain tube 220 are sealed. And, the design of water catch bowl 210 for in the air conditioner case 200, because the comdenstion water that produces under the evaporator refrigeration operating mode can gather in water catch bowl 210, the rethread drainage tube 220 flows out, is convenient for to the collection of the inside comdenstion water of air conditioner case 200.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention.
