Further, in the embodiment of the present invention, please refer to Fig. 3, Fig. 3 is a side view of the air conditioner defogging air outlet 2 in the air conditioner air outlet system of the bio-based composite material provided by the embodiment of the present invention, the air conditioner demisting air outlet 2 is upward Inclined and the included angle with the horizontal plane is θ, and θ satisfies 0°<θ≤15°.

At present, the plastic products used in vehicles, such as the current air-conditioning air outlet system for vehicles, are mostly petroleum-based materials. With the continuous reduction of petroleum reserves, the price of plastic products is also rising, and most petroleum-based materials are not biodegradable. . However, with the rapid development of the automobile industry, the life cycle of vehicle products is shortened, and a large number of scrapped vehicles flow into the waste vehicle treatment market, and the plastic products used in vehicles cannot be recycled, and the treatment requires a huge energy consumption, resulting in more CO2. emissions have caused serious environmental pollution problems. Therefore, in the embodiment of the present invention, the air outlet system of the air conditioner is made of bio-based composite materials. Parts can improve the recycling rate of vehicle products, avoid pollution to the ecological environment when disposing of waste products, and achieve the purpose of energy saving and emission reduction.

Based on the above-mentioned air-conditioning outlet system of bio-based composite material, an embodiment of the present invention also provides a vehicle, which includes any one of the above-mentioned air-conditioning outlet system of bio-based composite material, because the above-mentioned air-conditioning outlet system of bio-based composite material Having the above-mentioned technical effects, the vehicle based on the air-conditioning air outlet system of the bio-based composite material should also have corresponding technical effects.

To further optimize the above-mentioned technical solution, the present invention also provides a vehicle air-conditioning outlet system control method for the air-conditioning outlet system, please refer to Figure 4, which is a flow chart of the air-conditioning outlet system control method provided by the embodiment of the present invention , the control method includes the steps of:

S1: Detect the transmittance parameter of the predetermined position of the window;

S2: If the light transmittance parameter is less than the preset value, turn on the vehicle air conditioner and the air conditioner defogging outlet to supply air to the predetermined position of the window.

When the window is fogged or frosted, the air conditioner may be in two states of on or off. In order to avoid affecting the user's demand for the air conditioner, in the embodiment of the present invention, when the transmittance parameter is less than the preset value, the first detection The working status of the car air conditioner, if the car air conditioner is off, it is determined that the user does not need to use the air conditioner at this time. Fog defrosting operation, when the light transmittance parameter rises to not less than the preset value, turn off the car air conditioner and the air conditioner defogging outlet, stop the air supply, so as not to affect the user experience, if the car air conditioner is on, then judge If the user needs to use the air conditioner, he will turn on the demisting air outlet of the air conditioner to supply air to the predetermined position of the window, and when the light transmittance parameter is not less than the preset value, only close the demisting air outlet of the air conditioner, and keep the vehicle air conditioner to continue running, thereby Avoid turning off the car air conditioner to affect the normal use of the user.

As we all know, at present, the main air outlet of the air conditioner is generally in the normal open state. Therefore, as long as the vehicle air conditioner is turned on, the main air outlet of the air conditioner will supply air. If the user does not need to use the air conditioner at this time, it will affect the user experience. Therefore, in this In the embodiment of the invention, if the vehicle air conditioner is turned off, the main air outlet of the air conditioner is turned off while the vehicle air conditioner and the demisting air outlet of the air conditioner are turned on; if the air conditioner is turned on, there is no need to close the main air outlet of the air conditioner.
