Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the method for detecting the dust collecting state of a filter screen according to the embodiment of the present invention includes:
step S110, acquiring a current Air Quality Index (AQI) and a current historical dust collection amount of a filter screen. In this step, because the collection dirt volume of filter screen receives the influence of outside air quality, when using air purification device, the door and window is closed at home, but is not the sealed environment, and outdoor air still has partly to exchange the circulation with indoor air through the gap of door and window, and indoor can not rely on empty production air, and indoor air is all from outdoor. No matter close door and window, indoor air quality can all be influenced to outdoor air quality, and indoor particulate matter concentration is higher, and real-time dust collection volume just is higher, and on the contrary, real-time dust collection volume is lower. Outdoor Air Quality Indexes (AQIs) of various regions are updated on the network in real time every day, and the current air quality indexes can be acquired through network query. In this step, the current air quality index is queried on the network in real time, that is, the query is performed once every predetermined time (for example, 15 minutes), and the change of the air quality index is updated in time, so as to calculate the dust collection amount more accurately. The current historical dust collection amount of the filter screen is the accumulated dust collection amount of the filter screen after the air purification device is used for the last time.
And S120, calculating the real-time dust collection amount of the filter screen according to the preset particulate matter calibration value corresponding to the current air quality index and the running time. The real-time dust collection amount is the real-time dust collection amount when the air purification device operates, the real-time dust collection amount is m = x × t, wherein x is a particulate matter calibration value corresponding to the current air quality index, which is shown in table 1 and table 2 specifically, if the current air quality index is 125, namely, the type of mild pollution, at the moment, x = x 3 =95.5,t is the running time at this air mass index. If the air quality index changes during the time period in which the air cleaning device is operated, for example: when the system is started, the current AQI value is inquired to be 80, the AQI value is changed to be 125 after t time, then the system is continuously operated for t' time, and then the real-time dust collection amount m = x 2 ×t+x 3 ×t’。
TABLE 1AQI numerical value and particulate matter relation correspondence table
| AQI value | Class of AQI | Particulate matter (e.g., PM 2.5) 24 hours average/(microgram/cubic meter) |
| 0～50 | Superior food | 0～35 |
| 51～100 | Good wine | 36～75 |
| 101～150 | Slight pollution | 76～115 |
| 151～200 | Moderate pollution | 116～150 |
| 201～300 | Severe pollution | 151～250 |
| >300 | Severe pollution | >251 |
TABLE 2AQI values vs. particulate calibration values
In Table 2 above, the particle calibration value x 1 ～x 5 Median, x, of the corresponding concentration range of the particulate matter 6 Are end points. In order to more accurately obtain the particulate matter calibration value corresponding to the air quality index, the particulate matter calibration value corresponding to the air quality index has the following mapping relation:
for the endpoints of the air quality index range, the corresponding particulate matter calibration value is the endpoint of the corresponding concentration range of the respective particulate matter, for example: when the pollution is slight, the particulate matter calibration value corresponding to the air quality index 101 in the range from 101 to 150 is 76, the particulate matter calibration value corresponding to the air quality index 150 is 115, and the following examples are also included: the air quality index 300 corresponds to a particulate matter calibration of 251. For the middle value of the air quality index range, the corresponding particulate matter calibration value is obtained according to the following formula:
wherein b is the current air quality index, b min And b max Respectively, the minimum and maximum end points of the air quality index range in which b is located, a min And a max The minimum and maximum end points of the particulate matter concentration range corresponding to the air quality index range are respectively, and x is a particulate matter calibration value when the air quality index is b.
And the accumulated dust collection amount is more accurate when the particulate matter calibration value corresponding to the air quality index is obtained according to the mapping relation and the accumulated dust collection amount is determined subsequently.
Step S130, determining the current accumulated dust collecting amount of the filter screen according to the historical dust collecting amount and the real-time dust collecting amount, namely the current accumulated dust collecting amount m l ＝m h + m, wherein m h The historical dust collection amount. The current accumulated dust collection amount m is from the time when the filter screen is clean to the current time l It can also be expressed by the following formula:
wherein x is i Is x in Table 2 above 1 ～x 6 ，t i Is at x i Corresponding to the accumulated run time under AQI category.
Step S140, judging whether the filter screen reaches the corresponding N dust collection states or not according to the accumulated dust collection amount and N preset dust collection amount threshold values, wherein the N dust collection amount threshold values are set according to the dust containing amount of the filter screen, N is an integer larger than 1, and the ith dust collection amount threshold value is smaller than the (i + 1) th dust collection amount threshold value. In order to indicate the current dust collecting state of the filter screen of a user before the filter screen reaches the service life, the current dust collecting state of the filter screen is judged according to the current accumulated dust collecting amount and N preset dust collecting amount threshold values, and of course, the Nth dust collecting state corresponding to the Nth dust collecting amount threshold value is a state that the filter screen needs to be replaced or cleaned when the service life of the filter screen reaches.
And S150, prompting a user to replace or clean the filter screen when the filter screen reaches the ith dust collection state, and prompting the user to replace or clean the filter screen when the filter screen reaches the Nth dust collection state, wherein i =1,2, … and N-1. The specific accessible air purifier, air conditioner and fresh air system's respective display screen show tip information or send out the prompt tone in order reminding the user, and wherein, the tip information that shows can be the text message of changing or clearing up the filter screen. It should be noted that: the HEPA dust collection filter screen is directly replaced, and the electrostatic dust collection filter screen is cleaned.
And step S160, assigning the accumulated dust collection amount to the historical dust collection amount, and clearing the historical dust collection amount after a user replaces or cleans the filter screen. Specifically, after a user replaces or cleans the filter screen, the accumulated dust collection amount zero clearing operation can be actively executed, and after the zero clearing operation instruction is received, the historical dust collection amount is cleared.
In the filter screen dust collection state detection method of this embodiment, because the accumulative dust collection volume can reflect the filter effect of filter screen, accumulative dust collection volume is bigger promptly, the filter screen filter effect is worse, the current filter effect of filter screen is judged to current accumulative dust collection volume of accessible and N collection volume threshold value, consequently, to different users 'requirement to air quality, can reach the user of suggestion when the filter screen reaches the dust collection state before life (the filter screen can't filter almost), make the user change in advance or clear up the filter screen according to own demand.
In this embodiment, step S140 includes: determining that the filter screen reaches an ith dust collection state when the accumulated dust collection amount is larger than an ith dust collection amount threshold and is smaller than or equal to an (i + 1) th dust collection amount threshold; and determining that the filter screen reaches an Nth dust collection state under the condition that the accumulated dust collection amount is larger than an Nth dust collection amount threshold value.
Accordingly, step S150 includes: when the filter screen reaches the ith dust collection state, prompting a user to replace or clean the filter screen by adopting an ith prompting mode; and under the condition that the filter screen reaches the Nth dust collection state, an Nth prompting mode is adopted to prompt a user that the filter screen needs to be replaced or cleaned. Different prompting modes are adopted under different dust collecting states, so that the prompting mode which is easier to attract the attention of a user can be adopted under the condition that the dust collecting amount of the filter screen is larger.
Preferably, N =2 or 3, avoiding frequent prompting caused by setting too many dust collection amount threshold numbers.
Specifically, when N =3, step S140 includes:
and under the condition that the accumulated dust collection amount is judged to be larger than the first dust collection amount threshold value and smaller than or equal to the second dust collection amount threshold value, the filter screen reaches a first dust collection state.
Or, the filter screen reaches a second dust collection state when the accumulated dust collection amount is judged to be larger than the second dust collection amount threshold and smaller than or equal to a third dust collection amount threshold.
Or, the filter screen reaches a third dust collecting state when the accumulated dust collecting amount is judged to be larger than a third dust collecting amount threshold value.
The first dust collection amount threshold is smaller than a second dust collection amount threshold, which is smaller than a third dust collection amount threshold.
The third dust collecting state corresponds to a dust collecting state which needs to be replaced or deeply cleaned, that is, when the accumulated dust collecting amount is greater than a third dust collecting amount threshold, the filter screen needs to be replaced or cleaned, and the third dust collecting amount threshold is applicable to all users, and the dust collecting state which needs to be replaced or deeply cleaned can be understood as a minimum standard state, so that the third dust collecting amount threshold is set to be 1.5 times of the dust containing amount of the filter screen (generally, when the clean air output ratio CADR of an air purification product is reduced to 50%, the filter screen is considered to reach the dust containing amount, and actually, the filter screen has certain filtering capacity). First collection dirt state corresponds the collection dirt state that can change or slight clearance, the second collection dirt state corresponds the collection dirt state that can change or moderate clearance, these two collection dirt states do not have to be changed or clearance filter screen, therefore, first collection dirt volume threshold value and second collection dirt volume threshold value not only can be set for when the product leaves the factory, can also be the collection dirt volume setting value of receiving user's input as first collection dirt volume threshold value and second collection dirt volume threshold value, the user can set for by oneself according to own user demand, especially to some intelligent air purifier, intelligent air conditioner and intelligent new trend system, APP among the intelligent terminal that the user's accessible corresponds sets for. For example: the first dust collection amount threshold is set to be 60% -70% of the dust holding amount of the filter screen, and the second dust collection amount threshold is set to be the dust holding amount of the filter screen.
For N =3, step S150 includes:
the filter screen reaches under the condition of first collection dirt state, adopt first warning mode suggestion user, first warning mode is: and sending prompt information capable of replacing or cleaning the filter screen to a display screen of at least one of the product corresponding to the filter screen, the remote controller corresponding to the product and the intelligent control terminal for displaying. The displayed prompt message can be a text message for replacing or slightly cleaning the filter screen, and under the first prompting mode, some users with high requirements on air quality can replace or clean the filter screen, and other users can ignore the prompt.
