Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

The air intake system of the air conditioner for the vehicle as shown in fig. 1 comprises a filter assembly housing 1, wherein the filter assembly housing 1 is of a hollow structure, an air intake chamber 1a is arranged in the filter assembly housing 1, an opening 10 communicated with the air intake chamber 1a is formed on the end surface of the rear side, an air filter element 3 and an evaporator 4 are arranged in the filter assembly housing 1, wherein the evaporator 4 is close to the position of the opening 10 and completely covers the opening 10, and the air filter element 3 is arranged on one side of the evaporator 4 far away from the opening 10 in parallel.

As can be seen in fig. 2 to 4, the opening 10 is provided in a planar configuration so as to facilitate the butt assembly with the blower assembly housing 2, the blower assembly housing 2 is located entirely below the cabin interior instrument panel when the vehicle air conditioner is assembled to the vehicle, and the filter assembly housing 1 is mounted in the engine compartment.

Be equipped with on the outer wall of filter assembly casing 1 with the inner loop wind gap 1b and the outer loop wind gap 1c of air inlet chamber 1a intercommunication, and dispose inner loop wind door 1d and outer loop wind door 1e respectively, inner loop wind gap 1b and outer loop wind gap 1c all are located air filter 3 and keep away from one side of uncovered 10 and evaporimeter 4, make inner and outer circulation wind all need flow through behind air filter 3 rethread evaporimeter 4 and uncovered 10, so both promoted the interior air quality of car, also guaranteed the cleanness on evaporimeter 4 surface, ensure automobile air conditioner's steady operation, and increase of service life.

The inner circulation tuyere 1b is located at one side of the inlet chamber 1a and is oriented in correspondence with the opening 10 to facilitate the introduction of inner circulation air from the vehicle interior.

The external circulation air port 1c is located at the bottom of the air inlet chamber 1a, and the opening direction of the external circulation air door 1e faces to the front end of the filter assembly shell 1, namely, the side far away from the opening 10, so that the fresh air introduced by the external circulation air port 1c can directly blow to the air filter element 3 and the evaporator 4 under the condition of no roundabout turning, so that the air resistance of the fresh air inlet flow is reduced, and the air inlet efficiency is improved.

In order to prevent impurities from entering the air inlet chamber 10 through the external circulation air inlet 1c, a grid-shaped air inlet grille 18 is installed at the position of the external circulation air inlet 1 c.

The front end of the filter assembly housing 1 away from the opening 10 is provided with a cover plate 17, the cover plate 17 is opposite to the air filter element 3 and slightly inclines backwards, and the cover plate is installed through a buckle connection or other detachable modes so as to facilitate the installation and replacement of the air filter element.

Fig. 5 shows the internal structure of filter assembly housing 1 in detail, and it can be seen from fig. 6 that the inner wall of filter assembly housing 1 is provided with a drain groove 11 at a position corresponding to the bottom of evaporator 4, and the outer edge of the lower end of filter assembly housing 1 is provided with a drain hole 12 communicating with drain groove 11 for collecting and draining condensed water, and drain hole 12 is inclined toward the side away from opening 10.

In order to ensure the reliable support of the evaporator 4, a plurality of support ribs 16 extending along the length direction of the drain tank 11 are distributed at the bottom of the drain tank 11, and notches 16a distributed in a staggered manner are formed in each support rib 16, so that each channel separated by the support ribs 16 is communicated with each other.

The water baffle 13 which extends upwards and inclines outwards is arranged at the outer edge of the lower end of the opening 10 to prevent the air flow from bringing the condensed water into the vehicle, so that the phenomenon of 'water splashing' is formed, and a plurality of guide ribs 14 which extend along the longitudinal direction, namely the height direction of the water baffle 13, are distributed on the water baffle 13 so as to guide the condensed water blown onto the water baffle 13 to flow back to the drainage groove 11 through the gap between the end surface of the evaporator 4 and the opening 10.

In addition, in order to prevent the air flow from directly blowing toward the drain groove 11, the bottom wall of the filter assembly housing 1 is provided with an upwardly protruding wind deflector 15 at a position corresponding to between the air filter element 3 and the evaporator 4 to guide the air flow.

When the automobile air conditioner operates, the blower 21 installed in the blower assembly shell 2 is started, airflow is introduced from the inner circulation air inlet 1b or the outer circulation air inlet 1c according to a mode selected by a user, filtered by the air filter element 3, and sent into a vehicle through each air outlet after heat exchange between the evaporator 4 and the warm air core body.

Because the new trend flow of admitting air is smooth and easy, and the windage is little, is favorable to increasing intake and air inlet efficiency, promotes refrigeration effect, when utilizing vehicle air conditioner to defrost or the defogging, compares traditional vehicle air conditioner effect better to the noise is little, and the travelling comfort is good.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
