Automobile air conditioner air outlet adjusting device and air conditioner

Abstract

The invention discloses an automobile air conditioner air outlet adjusting device. The device comprises a first ventilation pipe and a second ventilation pipe, wherein one end of the first ventilationpipe communicates with an air outlet of an automobile air conditioner main machine, the other end of the first ventilation pipe communicates with one end of the second ventilation pipe, the other endof the second ventilation pipe leads to a cab, and an air outlet adjusting structure arranged on the second ventilation pipe can adjust the shape of the second ventilation pipe. The invention furtherdiscloses an air conditioner applying the air outlet adjusting device. According to the automobile air conditioner air outlet adjusting device, an existing automobile air conditioner air outlet ductwith a fixed shape is adjusted into an air conditioner air outlet duct comprising the second ventilation pipe with the shape capable of being changed under the action of external force, and the air outlet adjusting structure is arranged to adjust the shape of the second ventilation pipe, so that the purpose of changing the air outlet direction of the air conditioner is achieved, traditional guideblades are omitted, airflow distribution resistance is reduced, airflow noise is lowered, attractiveness is not affected, and more design space is reserved for automobile engineering development.

Description

technical field [0001] The invention belongs to the field of automobile interior decoration, and in particular relates to an air outlet regulating device of an automobile air conditioner. Background technique [0002] Automotive air conditioners are used to adjust the temperature inside the car to improve the comfort of the driver and passengers. In the prior art, the air outlet direction of the automobile air conditioner is mostly controlled by the adjustment device (such as guide vane) installed at the air outlet, and the guide vane is mostly arranged inside the air outlet, occupying the inner space of the air outlet, so that the air outlet can be used for The space for air flow is reduced, resulting in an increase in airflow velocity and airflow resistance, which can easily cause problems such as increased airflow noise, increased airflow resistance, and increased energy consumption of the vehicle; on the other hand, if figure 1 As shown, the arrow indicates the airflow ...

AI Technical Summary

Problems solved by technology

In the prior art, the air outlet direction of the automobile air conditioner is mostly controlled by the adjustment device (such as guide vane) installed at the air outlet, and the guide vane is mostly arranged inside the air outlet, occupying the inner space of the air outlet, so that the air outlet can be used for The space for air flow is reduced, resulting in an increase in airflow velocity and airflow resistance, which can easily cause problems such as increased airflow noise, increased airflow resistance, and increased energy consumption of the vehicle; on the other hand, if figure 1 As shown, the arrow indicates the airflow direction. When the airflow is in the direct blowing state, area A is the effective area for airflow circulation. When the airflow is in the non-direct blowing state, area B is the effective area for airflow circulation. Obviously, the cross-sectional area of ​​area A The sum is greater than the sum of the cross-sectional areas of area B, because in the non-direct blowing state, the guide vane is not parallel to the wall of the air duct, forming a large number of ineffective opening areas and a large number of dead areas of air flow, resulting in a smaller effective area for air flow , which will also increase the airflow velocity and airflow resistance, which in turn will lead to problems such as airflow noise and increased vehicle energy consumption.

[0003] In addition, in the patent text with publication number CN203857633U, a kind of automobile air conditioner air outlet regulating device without guide vanes is disclosed, such as figure 2 As shown, a universal elbow with any bending direction and angle is connected to the air outlet of the air conditioner, and the driver or passenger can change the position and direction of the air outlet by adjusting the angle and position of the universal elbow, but this device is exposed to the occupant The interior of the cabin affects the appearance and brings difficulties to the design of automotive products
