Initial air outlet mode control device of vehicle-mounted air conditioner and control method thereof

Abstract

The invention discloses an initial air outlet mode control device of a vehicle-mounted air conditioner, which comprises an air blower, a common air duct, a defrosting air duct, a blowing surface air duct and a blowing foot air duct, wherein the common air duct is respectively connected with the defrosting air duct, the blowing surface air duct and the blowing foot air duct, the air blower is connected with the air inlet of the common air duct, the initial air outlet mode control device comprises a first air door and a second air door, which are used for controlling the closing of the defrosting air duct, the blowing surface air duct and the blowing foot air duct, and the first air door and the second air door are connected with the lower layer of the common air duct through a bearing, andthe bearing is connected with an output shaft of the automobile motor. According to the invention, the overheated or too cold initial air outlet of the automobile air conditioner can be prevented frombeing directly blown to drivers and passengers, meanwhile, after proper time delay, the air temperature in the air duct tends to be stable, the air door is controlled to rotate, the defrosting mode and the foot blowing mode are closed, and the surface blowing mode is opened, and the comfort of the automobile air conditioning system is improved.

Description

technical field [0001] The invention relates to the field of vehicle-mounted air conditioners for new energy vehicles, in particular to a device for controlling the initial air outlet mode of a vehicle-mounted air conditioner and a control method thereof. Background technique [0002] With the gradual development of China's economy, cars have become an essential device for every family to travel. At this stage, not only is the vehicle required to be able to shelter from wind and rain, but comfort is also the goal pursued by most consumers. The comfort of air conditioning is one of them. Gentle warm air is provided indoors, and the cooling and heating performance is a key factor to measure the performance of the air conditioner. In summer, especially after the vehicle has been exposed to the sun for a long time in a high-temperature outdoor environment, the temperature inside the vehicle is generally high. When the driver enters the vehicle, he will generally turn on the ign...

AI Technical Summary

Problems solved by technology

In summer, especially after the vehicle has been exposed to the sun for a long time in a high-temperature outdoor environment, the temperature inside the vehicle is generally high. When the driver enters the vehicle, he will generally turn on the ignition and turn on the air conditioner. The air temperature inside is usually relatively high, the highest temperature can reach 70 degrees, because a certain amount of high-temperature gas has accumulated in the air duct, when the air conditioner is turned on, the blower will blow out the hot air in the air duct as soon as possible when it is working, most Under certain circumstances, the air conditioner mode is the internal circulation blowing surface mode before the vehicle is turned off, so when the driver turns on the car air conditioner again, the blowing mode of the air conditioner is still the mode before the engine is turned off. The hot air in the air duct is directly blown to the driver's face in the air conditioner blowing surface mode at the first time, so that the driver can feel the high temperature gas in the air duct at the first time, which makes the driver feel uncomfortable and reduces the impact on the performance of the air conditioner. first impression
