Detailed Description
The following describes in further detail embodiments of the present invention with reference to the accompanying drawings.
A purifying system of an air filter of an automobile air conditioner comprises a main control part, a power supply part, an input part and an execution part. The main control part is a singlechip 2, the power supply part is a power supply 1, the input part is a starting switch 7, a forced switch 8 and a dust sensor 3, and the execution part is a relay 4, a fan 5 and an alarm lamp 6, as shown in figure 1.
To this vehicle air conditioner air cleaner clean system's main control part, singlechip 2 receives the information of dust sensor 3, opens or closes the fan 5 of installing in vehicle air conditioner inlet air duct, controls alarm lamp 6 simultaneously and shows three kinds of colour alarm signal red, yellow, green of air cleanliness. The air pollution level is preferably established as inhalable particulate matter PM10 in the environmental air quality standard (GB 3095-1996). Red for heavy contamination, yellow for medium contamination, green for normal air cleanliness. The singlechip 2 preferably adopts a 32-bit embedded singlechip as a control core.
For the power supply part of the air filter purification system of the automobile air conditioner, in order to conveniently purify the air filter when the automobile is stopped, the direct current 12V of the original automobile storage battery is adopted to supply power for the fan 5, and meanwhile, the 12V of the original automobile storage battery is preferably converted into 5V through a power supply voltage reduction chip to supply power for the singlechip 2, the dust sensor 3 and the alarm lamp 6.
For the input part of the air filter purification system of the automobile air conditioner, the starting switch 7 is responsible for switching on the power supply 1 of the system, the forced switch 8 is responsible for manually turning on or turning off the fan 5, and the dust sensor 3 is responsible for detecting the cleanliness of air in an air inlet channel of the automobile air conditioner and transmitting signals to the singlechip 2. The dust sensor 3 preferably employs a PM10 sensor. In order to accurately detect the air cleanliness of the air inlet channel of the automobile air conditioner, the dust sensor 3 is arranged between an air filter and an evaporator of an air inlet system of the automobile air conditioner. The start switch 7 and the forced switch 8 are mounted on the center console.
For the execution part of the air filter purification system of the automobile air conditioner, a fan 5 is arranged between the air filter and the evaporator of the air inlet channel of the automobile air conditioner. To ensure that the dust of the air cleaner is blown out of the vehicle, the wind direction of the fan 5 is from the inside of the vehicle to the outside of the vehicle. The fan 5 is preferably an axial fan comprising 2 gears: high speed and low speed, respectively corresponding to heavy pollution and medium pollution of the air filter.
The alarm lamp 6 can be installed by drilling a through hole in a central instrument desk of the automobile, preferably selects LED patch lamp beads, and preferably selects power of 2-3V.
The working modes of the air filter purification system of the automobile air conditioner comprise 2 modes. The first automatic control mode is as follows: after the starting switch 7 is manually closed, the system is switched on, and the singlechip 2 starts to work; if the dust sensor 3 detects that the air cleanliness is in severe pollution or moderate pollution, the single chip microcomputer 2 controls the fan 5 to automatically run at a high speed or run at a low speed, and meanwhile, the single chip microcomputer 2 controls the alarm lamp to display the air cleanliness in red, yellow and green colors; when the air is clean, the single chip microcomputer 2 stops the work of the fan 5. The second manual control mode is as follows: the air cleaner of the automobile air conditioner can be purified by manually starting or stopping the operation of the fan 5 through the forced switch 8 regardless of the air cleanliness of the intake passage.
Since the power source 1 of the system is supplied by the original vehicle battery, the system can be turned on to perform air cleaner purification when the vehicle is stopped.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that; various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims, and therefore, the scope of the present invention is not limited to the disclosure of the embodiments and the accompanying drawings.
