DETAILED DESCRIPTION OF THE INVENTION
The vehicle air conditioner device according to the embodiments of the present invention will now be described in detail below with reference to the drawings.
FIG. 1 is a block diagram showing a vehicle air conditioner device 10 according to the first embodiment of the present invention. The vehicle air conditioner device 10 comprises an air purifying unit 110, an inside air quality acquiring unit 120, an outside air quality acquiring unit 130 and a display unit 140. The inside air quality acquiring unit 120 comprises a vehicle inside particle sensor 121 and an odor sensor 122, while the outside air quality acquiring unit 130 comprises a vehicle outside particle sensor 131.
The air purifying unit 110 is configured to purify the air inside the vehicle or the extracted external fresh air. For example, the over-standard air inside the vehicle or the external fresh air can be extracted into the purifying unit, and then a relatively clean and healthy air is discharged to the inside of the vehicle by purifying. The air purifying unit 110 is, for example, a filter with activated carbon.
The vehicle outside particle sensor 131 is disposed outside the vehicle and is configured to detect the content of specific particles, such as PM 2.5(inhalable particles with diameters smaller than 2.5 micrometers) or Total Suspended Particulate, in the ambient air (air outside the vehicle), and send the detection result of the particle content to the outside air quality acquiring unit 130. Then, the outside air quality acquiring unit 130 compares the detected particle content in the ambient air with grading standard values so as to obtain the air quality of the ambient air. The grading standard values usually have been built into the outside air quality acquiring unit 130 at the beginning of the vehicle leaving factory, and the data source thereof may either be the air quality grading standard data published by the country where the vehicle is sold or by the relevant international organization, or the standard data voluntarily set by the vehicle manufacturer based on actual needs, as long as it can objectively distinguish the good air quality from the bad air quality. Moreover, the outside air quality acquiring unit 130 can also receives the air quality of the area where the vehicle locates from the outside world in a wireless communication manner such as GPRS, 3G network or WLAN.
The vehicle inside particle sensor 121 is disposed inside the vehicle and is configured to detect the content of specific particles in the air inside the vehicle and send the detection result to the inside air quality acquiring unit 120. The odor sensor 122 is disposed inside the vehicle and is configured to detect odor in the air inside the vehicle and send the detection result to the inside air quality acquiring unit 120. The inside air quality acquiring unit 120 evaluates the air quality inside the vehicle based on the detected particle content and/or odor so as to obtain the air quality inside the vehicle. Similarly, the air quality evaluation standard may either be the evaluation standard published by the relevant country or organization, or the evaluation standard voluntarily set by the vehicle manufacturer based on actual needs. For example, the air quality inside and outside the vehicle can be divided into six levels, that is, excellent, good, slight, light, moderate and heavy. Of course, the division of the air quality into levels is not limited to the above-mentioned manner. For example, the air quality levels can be directly set as "Level 1, Level 2, Level 3 ..." The inside air quality acquiring unit 120 and the outside air quality acquiring unit 130 respectively send the display data of the air quality inside and outside the vehicle to the display unit 140 so that the user inside the vehicle can view the display data. The display unit 140 may be, for example, a liquid crystal display.

The fourth embodiment differs from the third embodiment in that the fourth embodiment also comprises an ionizer shutoff unit 162. The other content of the fourth embodiment is the same as the third embodiment.
The ionizer shutoff unit 162 is configured to shut off the ionizer 160 after the air quality inside the vehicle has reached the desired air quality for a predetermined time period. Accordingly, this embodiment can automatically control the operation of the ionizer by using the ionizer start-up unit 161 and the ionizer shut-off unit 162. Moreover, the user can also manually control the ionizer 160. For example, the ionizer start-up unit 161 and the ionizer shutoff unit 162 can be shut off via the input unit 150. At this time, it is only possible to control the starting up and shutting off of the ionizer 160 via the input unit 150.
In addition, although the above-mentioned embodiments evaluate the air quality by using odor and particle content, the present invention is not limited to this. For example, a harmful gas sensor can be provided inside or outside the vehicle to acquire a more comprehensive air quality evaluation by detecting harmful gas.
The above are merely preferred embodiments of the present invention, which are used to describe the present invention rather than limit the present invention. For the one skilled in the art, any modification, equivalent replacement, improvement or the like within the spirit and principle of the present invention should be included in the protection scope of the present invention.
