Embodiment Construction

[0016] Such as Figure 1~Figure 2 A car air-conditioning drain pipe structure is shown, comprising a housing 1, a rubber drain pipe 2, a housing drain pipe 3 arranged on the housing 1, the rubber drain pipe 2 is provided with a drain pipe inlet 4, and the The end of the casing drain pipe 3 is sleeved into the water inlet 4 of the drain pipe for connection. A clamping hole 5 is provided on the pipe wall of the water inlet 4 of the drain pipe. The outer wall of the end of the casing drain pipe 3 is provided with a positioning boss 6 that can be snapped into the snap hole 5 . The end of the housing drain pipe 3 is in interference fit with the water inlet 4 of the drain pipe. The casing drain pipe 3 is a plastic drain pipe.

[0017] After the housing drain port 2 of the housing 1 is inserted into the drain pipe inlet 4 of the rubber drain pipe 2, the positioning boss 6 snaps into the clamping hole 5, thereby completing the assembly and assembly of the rubber drain pipe 2 and th...

Abstract

The invention discloses a drainage pipe structure for an automobile air conditioner, which comprises a housing, a rubber drainage pipe and a housing drainage pipe arranged on the housing, wherein a drainage pipe water inlet is formed on the rubber drainage pipe, and the end of the housing drainage pipe is inserted into and connected with the drainage pipe water inlet. With the structure, the drainage pipe structure has the advantages as follows: (1) the cost is low, no binding tape is needed, no tool is needed, and the installation operation is convenient; and (2) as the protrusion on the plastic housing is engaged with the hole in the rubber drainage pipe, the effects of both fixing and positioning the rubber drainage pipe are achieved, the assembly process is very simple, the drainage pipe is prevented from falling off after assembly, and the reliability is high. Besides, based on the feature that rubber is elastic, the rubber drainage pipe and the plastic housing are in interference fit, so as to improve the leak tightness between the plastic housing and the drainage pipe and avoid water leakage at the assembly site.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an automobile air conditioner drainage pipe structure. Background technique [0002] When the car air conditioner is in the cooling state, the surface temperature of the evaporator is very low, and a large amount of condensed water is generated when the air passes through the surface of the evaporator. The rubber drain pipe can lead the condensed water to the outside of the car to prevent water accumulation in the car. [0003] At present, cable ties are mainly used to fix the rubber drain pipe and the plastic housing. After the rubber drain pipe is put on the drain port of the plastic housing, the drain pipe is fastened with a cable tie. The drain pipe in this installation method is generally not easy to fall off. There is also a fixing method, which is to directly cover the rubber drain pipe on the drain port of the plastic shell. This installation method is...
