Abstract
A waterproof guiding device of expansion valve of air-conditioning box, includes: the rubber sleeve is arranged between the lower shell of the air-conditioning box and the evaporator pipeline so as to realize waterproof flow guide of the air-conditioning box; rubber sleeve excessive cooperation with lower casing and evaporimeter pipeline respectively, this rubber sleeve includes in proper order: the front end is raised, the wave transition section and at least two circles of blocking ribs. The utility model has simple structure, and the mould of the lower shell is simple, thereby reducing the mould cost; the utility model discloses can assemble alone on the evaporimeter pipeline, after expansion valve and evaporimeter assembled, accomplish the gas tightness and detect just can be together with lower casing assembly, for the production line assembly provides facility.
Description
Technical Field
The utility model relates to a technique in vehicle-mounted air conditioner field specifically is a waterproof guiding device of expansion valve of air-conditioning box.
Background
The expansion valve is generally located at the joint between the inside and the outside of a compartment and has a sealing requirement, and the expansion valve is partially similar to a vehicle rear air conditioner, because of the requirement of layout, the joint can be arranged at the bottom of a vehicle body, and meanwhile, the requirement of preventing evaporator condensate water is increased, in the case of the conventional sealing mode, the rubber sealing mode and the shell secondary injection molding process mode are adopted, but the structure brings high mold cost. In addition, because the soft rubber is embedded and wrapped on the shell, the expansion valve can be assembled only after the evaporator pipeline assembly is arranged on the shell, and inconvenience is brought to the air tightness detection of the expansion valve.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is not enough to the above-mentioned that prior art exists, provides a waterproof guiding device of expansion valve of air-conditioning box, still the cost is reduced when satisfying waterproof nature.
The utility model discloses a realize through following technical scheme:
The utility model discloses a: the rubber sleeve is arranged between the lower shell of the air-conditioning box and the evaporator pipeline to realize the waterproof flow guide of the air-conditioning box.
Rubber sleeve excessive cooperation with lower casing and evaporimeter pipeline respectively, this rubber sleeve includes in proper order: the front end is raised, the wave transition section and at least two circles of blocking ribs.
And a drainage groove for draining condensed water is arranged on the upper surface of the rubber sleeve.
The lower shell is provided with at least one circle of sealing wall matched with the rubber sleeve blocking rib.
Technical effects
compared with the prior art, the utility model has simple structure, and the mould of the lower shell is simple, thereby reducing the mould cost; the utility model discloses can assemble alone on the evaporimeter pipeline, after expansion valve and evaporimeter assembled, accomplish the gas tightness and detect just can be together with lower casing assembly, for the production line assembly provides facility.
Drawings

Fig. 2 is a top view of the present invention disposed on the rear air-conditioning box;
FIG. 3 is a cross-sectional view of the sealing structure of FIG. 2;
FIG. 4 is a schematic view of the sealing structure of the present invention;
in the figure: the evaporator comprises an evaporator pipeline 1, a rubber sleeve 2, an expansion valve 3, a lower shell 4, a drainage channel 5, a front end bulge 6, a blocking rib 7, a wave transition section 8 and a sealing wall 9.
Detailed Description
as shown in fig. 1 to 4, in the present embodiment, a rubber sleeve 2 is disposed between a lower casing 4 of the rear air-conditioning box and an evaporator pipeline 1 to achieve waterproof flow guiding of the rear air-conditioning box.
Rubber sleeve 2 respectively with 1 interference fit of casing 4 and evaporimeter pipeline down, this rubber sleeve 2 includes in proper order: front end bulge 6, wave transition section 8 and two rings of stop ribs 7.
As shown in fig. 2, the upper surface of the rubber sleeve 2 is provided with a drainage groove 5 to ensure that condensed water can be drained in time.
As shown in fig. 4, a sealing wall 9 is provided on the lower housing 4 to engage with the rib 7 of the rubber sleeve 2.
The above device works by the following ways: after the rubber sleeve 2 is assembled on the evaporator pipeline 1, the expansion valve 3 is also assembled on the evaporator pipeline 1, and after the air tightness detection is finished, the rubber sleeve is assembled with the lower shell 4. Adopt interference fit between the protruding 6 of front end of rubber sleeve 2 and the evaporimeter pipeline 1, prevent that the comdenstion water on the evaporimeter pipeline 1 from revealing, also adopt interference fit between two rings of shelves muscle 7 of rubber sleeve 2 and the round sealed wall 9 of casing 4 down, prevent that the evaporimeter comdenstion water of casing 4 from revealing down. As shown in fig. 3, the wavy transition section 8 of the rubber sleeve 2 is used to compensate for a part of manufacturing and assembly tolerances to ensure that the sealing effect is not affected by manufacturing and assembly deviations.
The foregoing embodiments may be modified in various ways by those skilled in the art without departing from the spirit and scope of the present invention, which is not limited by the above embodiments but is to be accorded the full scope defined by the appended claims, and all such modifications and variations are within the scope of the invention.
Claims (3)
1. The utility model provides a waterproof guiding device of expansion valve of air-conditioning box which characterized in that includes: set up the rubber sleeve between the lower casing of air-conditioning box and the evaporimeter pipeline, this rubber sleeve is full of the cooperation with lower casing and evaporimeter pipeline respectively, and this rubber sleeve includes in proper order: the front end is raised, the wave transition section and at least two circles of blocking ribs.
2. An expansion valve waterproof deflector of an air conditioning unit as claimed in claim 1, wherein a drain groove for draining condensed water is provided on an upper surface of the rubber sleeve.
