When the vehicle speed is too high, the air leakage of the air conditioning box is more obvious when the air pressure outside the vehicle is far greater than the air pressure inside the vehicle, more energy loss is caused in this time, the performance of the air conditioning assembly is greatly reduced, the effects of saving energy and reducing emission, improving efficiency and improving air quality are not achieved, more effective resources are wasted, and therefore the safety and the comfort of drivers and passengers are affected, so that in the field of automobile air conditioning, the realization of the air conditioning box product with adjustable internal and external mixed air inlet proportion can not be realized through independent control of an air door at present, and because the internal and external air inlet mixed area is arranged on a filter, no special structure is independently sealed, and the internal and external mixed air inlet proportion cannot be realized at.

The utility model provides an air conditioner air inlet box of subregion air inlet, please refer to and draw together figure 1, fig. 2, this structural design contains two air doors (inner loop air door 3, outer loop air door 1), the last bellows unit of traditional technology increases air door seal structure (the sealed muscle of first subregion 4, the sealed muscle of second subregion 6) and carries out the subregion air inlet with filter 5, divide into outer loop air inlet district (A district), mix air inlet district (B district), inner loop air inlet district (C district), just so can realize the air inlet state of six independent differences of mould, please refer to and draw together figure 3, fig. 4, every air inlet mode all can change the air door angle and realize that the air inlet proportion is controllable, wind and whistling can not appear scurrying.

The utility model discloses an air inlet case casing 2 that is used for inhaling interior and the outer air of car realizes the inner loop and the extrinsic cycle air door 1 of different air inlet modes, and the preferred butterfly air door of air door structure also can adopt other structures that can realize the six air inlet states of air inlet case unit. The air intake box shell 2 is provided with an internal circulation air inlet 7 and an external circulation air inlet 8. The internal circulation air inlet 7 is used for five air inlet modes of a state two, a state three, a state four, a state five, a state six and five in fig. 3, and the external circulation air inlet 8 is used for five air inlet modes of a state one, a state two, a state three, a state four, a state five and five in fig. 3. The air inlet mode is increased to six on the basis of the traditional air inlet box unit of the automobile air conditioner, wherein the air inlet proportion can be adjusted in the air inlet modes of the state three and the state five.

Referring to fig. 5(1), the position a1 is the fully closed mode of the internal circulation damper 3, the position B1 is the fully open mode of the internal circulation damper 3, and the dashed line indicates the adjustable damper; the position a1 is an external circulation air door 1; referring to fig. 5(2), the position a1 is the fully closed mode of the outer circulation damper 1, the position b1 is the fully open mode of the outer circulation damper 1, and the dashed lines indicate the adjustable dampers.

The utility model provides an air inlet box casing 2 is formed by two sub-casing equipment, divide into independent A, B, C district air inlet with filter 5 through the sealed muscle of first subregion 4 and the sealed muscle of second subregion 6, and A, B, C regional air inlet size does not receive the utility model discloses the drawing restriction can be according to experimental result and CAE report and do final definite. The two circulation dampers are preferably butterfly dampers. The butterfly arm length of the internal circulation air door 3 comprises L1 and L2, and the two butterfly arms with the length of L1 and L2 can be designed in parallel or in an included angle, and L1 is preferably greater than or equal to L2. If L1 is less than L2, in the state, the speed of the air entering outside the automobile is high, a negative pressure area is generated in the air inlet box, the deformation caused by the deterioration of the deformation resistance of the arm length L2 is caused all the year round, and the whistling is easy to occur.

Similarly, the butterfly arm lengths of the outer circulation damper 1 include l1 and l2, the two butterfly arms with the lengths of l1 and l2 can be designed in parallel or in an included angle, l1 is preferably greater than or equal to l2, and if l1 is smaller than l2, the outer circulation damper 1 is deformed due to the deformation resistance and is also prone to squeaking under the condition of bearing high wind pressure in the year-round period.

Generally, in hot summer, the air conditioner is in a cooling mode, and at the moment, the air in the vehicle is quickly cooled to reach the most comfortable temperature of a human body by selecting the internal circulation air inlet. When the air in the vehicle is recycled for too long time, the quality of the air in the vehicle is deteriorated and peculiar smell is generated.
