The mixed air supply structure technology mainly has the problems that:
1. the used air door is of a single air door structure, if the air door is controlled to be in a middle stroke, air in/out of a vehicle can enter simultaneously, and in the driving process of the vehicle, the air door is pushed by wind pressure, the air door is easy to swing, parts are accelerated to be worn, and abnormal sound can be generated;
2. the used air door is of a single air door structure, if the air door is controlled to be in a middle stroke, air inside/outside the vehicle can enter simultaneously, and in the running process of the vehicle, air can directly enter the vehicle due to high pressure of an air channel outside the vehicle, and partial air can not enter the impeller, so that the air volume of the air conditioning box is reduced, and the performance of the air conditioner is reduced;
3. air inside the automobile and air outside the automobile cannot be independently supplied, the humidity of the air inside the automobile is high when mixed air is supplied, the air conditioner is easy to fog when blowing to the window glass, and potential safety hazards of driving exist;
4. the air inside the air conditioner and the air outside the air conditioner can not be independently supplied, and the air conditioner evaporation box is difficult in structural design and complex in structure on the problems of low demand of human bodies on the head temperature and high demand on the foot temperature;
5. the bottom of the motor is directly contacted with air in the vehicle, and when the rotating speed of the blower is reduced, obvious brush noise is generated, and discomfort of passengers is easily caused.
The second is a double-layer air supply structure. The working principle is as follows: the air outside the vehicle is blown to the upper air channel by the upper impeller of the blower after passing through the filter screen by the air channel outside the vehicle. The air in the vehicle passes through the filter screen from the air channel in the vehicle and is blown to the air channel at the lower part by the impeller at the lower part of the blower. Wherein the air channel outside the vehicle is communicated with the air channel at the upper part to jointly form an outer air channel, and the air channel inside the vehicle is communicated with the air channel at the lower part to jointly form an inner air channel. The inner gas passage and the outer gas passage are separated by a partition plate.
The double-layer air supply structure technology can realize independent air supply of air outside the vehicle and air inside the vehicle, and has the main problems that:
1. the impeller has a longer distance from the end face of the blower, and the distance is about the total height 1/4 of the impeller, so that the height size of the blower is increased, and the size of a product is enlarged;
2. the impeller and the motor are complex to assemble, the height of the impeller is increased, the top of the impeller shakes, and the dynamic balance of the blower is difficult to control. The product yield of the blower is reduced;
3. the bottom of the motor is directly contacted with air in the vehicle, and when the rotating speed of the blower is reduced, obvious brush noise is generated, so that discomfort of passengers is easily caused;
4. the blower can generate heat during working, and the heat needs to be provided with special heat dissipation channels on the blower and the plastic shell so as to cool the blower, so that the structural complexity of the product is increased;
5. interior air door and the use of outer air door are fan-shaped air door, and this air door product size is great, and weight is heavier simultaneously, is contradictory to lightweight design theory.
