Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 is the realization flow figure of the clean based reminding method of the filter screen of air conditioner that one embodiment of the invention provides; For convenience of explanation, illustrate only part related to the present embodiment, as shown in the figure:
After air-conditioner start runs:
Step S110: obtain once current dust concentration value A every preset time period ti.
Step S120: obtain corresponding coefficient Xi according to described dust concentration value A.
Step S130: the value being obtained accumulative operational factor TB by the value calculating each Xi*ti, wherein TB=∑ Xi*ti.
Step S140: when described accumulative operational factor TB meets or exceeds preset value, controls the information sending cleaning filter net.
In the present embodiment, consider that the different dirty degree to filter screen of air conditioner of dust concentration in air also can be different, therefore, in the running of air-conditioner, just once current dust concentration value A is obtained at interval of a preset time period ti, and then obtain the coefficient Xi corresponding with described dust concentration value A, the value of accumulative operational factor TB is obtained by the value of the product Xi*ti calculating these two parameters; When accumulative operational factor TB meets or exceeds preset value, control the information sending cleaning filter net.
When specific implementation, air-conditioner controller obtains once current koniology concentration value A at interval of the fan operation time period t i preset, and obtains corresponding coefficient Xi, and calculate accumulative operational factor TB according to ∑ Xi*ti by the mode calculating or transfer.
Such as, certain a air-conditioner is in its running, and as shown in Figure 2, as seen from the figure, in continuous print more than 20 hours, its dust concentration value A obtained becomes curvilinear motion to the dust concentration value of acquisition.When obtaining corresponding coefficient Xi, can according to the dust concentration value A obtained divided by some preset values, occurrence is as Xi=A/40.See Fig. 2, be the 2nd hour moment operationally, the dust concentration value A that it collects is 50, then coefficient Xi=50/40=1.25; Be the 14th hour moment operationally, the dust concentration value A that it collects is 112, then coefficient Xi=112/40=2.8.In fact, the selection of its preset value is determined by the experiment in product development process, determines that different dust concentration values is on the impact of accumulative operational factor specifically by experiment.
On the other hand, corresponding with dust concentration value A coefficient Xi also obtains by tabling look-up.Such as, controller can store coefficient Xi corresponding to variable concentrations value A in memory.Sometimes the overabundance of data in order to avoid storing, also can store by stages, as the interval at interval of concentration value being 5 stored data, specific as follows:
| Concentration value A | 25 | 30 | 35 | 40 | 45 | 50 |
| Coefficient Xi | 0.5 | 0.75 | 0.875 | 1 | 1.125 | 1.25 |
Can adopt nearby principle when tabling look-up, the dust concentration value A as current acquisition is 26, then the desirable coefficient value Xi corresponding with 25 that table look-up is 0.5, and if current dust concentration value A is 48, then the desirable coefficient value corresponding with 50 of tabling look-up is 1.25; Certainly, coefficient Xi also can get interpolation calculation according to list data, such as existing concentration value A is 48, with interpolation calculation Xi=1.125+ (48-45) * (1.25-1.125)/(50-45)=1.2, more accurate by interpolation calculation.Certainly, no matter mentioned here be obtain coefficient Xi by calculating or look into list data, is all only example, and be not used in and limit.
Further, the preset time period ti obtaining dust concentration value A can be chosen as 1 second to some seconds, even several hours.Be understandable that, preset time period ti is shorter, and the accumulative operational factor TB calculated is more accurate, and the calculative amount of certain air-conditioner controller also can increase.Such as, can get and namely within 0.25 hour, obtain a dust concentration value A every 15 minutes, calculate or transfer corresponding coefficient X.If the interval acquiring every 15 minutes in 1 hour of air-conditioner operation is respectively 0.5,0.75,0.875,1 to current corresponding coefficient Xi (i=1,2,3,4), then the result of calculation of the accumulative operational factor TB in this 1 hour is: TB=∑ Xi*ti=(X1+X2+X3+X4) * ti=(0.5+0.75+0.875+1) * 0.25=0.78125.When accumulative operational factor TB exceed preset value as 200 time, the defeated information cleaning out filter screen of air-conditioner controller.
According to the clean based reminding method of the filter screen of air conditioner that the present embodiment provides, consider the impact of air quality on the dirty degree of filter screen of air conditioner, in time screen pack can be cleaned by more reasonable reminding user exactly, prevent refrigeration from reducing, and can effectively reduce growing of bacterium, more be conducive to health.
In specific implementation process, as a preferred embodiment, when calculating the value of accumulative operational factor TB, except considering the coefficient value Xi corresponding with dust concentration value A, the acquisition to rotation speed of fan value or gear value C can also be added, obtain other coefficient value Yi with this.Known by experiment, under different speed conditions, be different by the air quantity of screen pack, obviously higher wind speed, more by the air quantity of screen pack, when other environmental conditions are identical, wind speed is higher, then the control of dust on screen pack is more.When considering dust concentration value A and rotation speed of fan value or gear value C, the computing formula of accumulative operational factor TB becomes TB=∑ Yi*Xi*ti.
Specific implementation process is see Fig. 3.Namely Fig. 3 is the realization flow figure of the clean based reminding method of the filter screen of air conditioner that the preferred embodiment of the present invention provides.As shown in Figure 3:
After air-conditioner start runs:
Step S210: obtain once current dust concentration value A every preset time period ti, obtain current rotation speed of fan value or gear value C simultaneously.
Step S220: obtain corresponding coefficient Xi according to described dust concentration value A, obtains the coefficient Yi corresponding with it according to described rotation speed of fan value or gear value C.
Step S230: the value being obtained accumulative operational factor TB by the value calculating each Yi*Xi*ti, wherein TB=∑ Yi*Xi*ti.
Step S240: when described accumulative operational factor TB meets or exceeds preset value, controls the information sending cleaning filter net.
In the present embodiment, compared with above-mentioned first embodiment, except considering coefficient value Xi, also adding the acquisition of rotation speed of fan, obtaining other coefficient value Yi with this.Further, the acquisition of rotation speed of fan also has two kinds of forms at least, and one is obtain concrete rotation speed of fan value; Two is the gear value obtaining rotation speed of fan.When blower fan is stepless time adjustment motor, can consider preferentially to be calculated by formula to obtain Yi, the range of speeds as the air-conditioner blower fan of a certain model is 400 revs/min-1500 revs/min, its coefficient Yi can be real-time rotate speed value divided by some preset values as 800, as rotating speed be 500 revs/min time, Yi=500/800=0.6; Can certainly adopt the method for tabling look-up, its method is same as the previously described embodiments.When the rotating speed of blower fan is fixing gear, look-up method can be paid the utmost attention to.Because gear is limited, the data needing it to table look-up are just few, as when a rotation speed of fan is basic, normal, high third gear, and can be easily as long as store three data.
Same, after having calculated or transferred coefficient Yi, accumulative operational factor TB just can obtain by calculating TB=∑ Yi*Xi*ti in real time.When accumulative operational factor TB exceedes a certain preset value as 200 time, air-conditioner controller controls to send the information of cleaning filter net.
In fact, according to the clean based reminding method of the filter screen of air conditioner that above-mentioned two embodiments provide, after user carries out cleaning to screen pack, air-conditioner controller will stop information, and accumulative operational factor TB is before reset, then reclocking, to enter next stage.
Further, as a preferred embodiment, the clean based reminding method of filter screen of air conditioner provided by the invention, user can add up the value of operational factor TB by sets itself.That is, user is in the middle of the process of using air-condition device, the actual dust situation of the filter screen observed when the cumulative time that can use according to reality and cleaning filter net, from Row sum-equal matrix and the accumulative operational factor TB of setting.User sets by remote controller, if or air-conditioner and mobile terminal device such as mobile phone set up communication, set this parameter by the such as mobile terminal such as mobile phone.When air-conditioner controller sends the information of cleaning filter net, user finds that the actual laying dust on screen pack is also few, and now user can perform the accumulative operational factor TB value that amendment is preset, and increases, preset value as changed 220 into from 200; Or user finds that laying dust reality on screen pack too much, and preset value can reduce by user, as changed 180 etc. into by 200.In a word, user adds up the value of operational factor TB by sets itself, accurately can meet the environment for use of user further, reach and remind more accurately.
In specific implementation process, for the step of " obtaining once current dust concentration value A every preset time period ti ", there is several implementation.Such as, first air-conditioner controller can directly obtain current koniology concentration value A by dust sensor.Generally, dust sensor is just arranged on the inside of air-conditioner, and dust sensor, as the device of air conditioner built-in, can directly provide current dust concentration value A to air-conditioner controller.
Certainly, the current dust concentration value A that air-conditioner controller obtains be may not be and obtained by built-in dust sensor, but by be arranged on indoor air detection device talk after obtain, as by other air detection equipment in same family such as the equipment such as air purifier or air box obtain.General all with dust sensor on these air detection equipment, air-conditioner controller can get the dust concentration value A of current indoor after passing through communication with it.By mode like this, one in family or multiple stage air-conditioner all can obtain current dust concentration value with air detection device talk, and do not need to arrange separately dust sensor on each air-conditioner, the dust sensor high relative to cost compare, this is conducive to the cost reducing air-conditioner, and this is also the trend of following Internet of Things.
On the other hand, air-conditioner may not be and obtains present air dust concentration value A by dust sensor (no matter be built-in or in other air detection equipment), air-conditioner directly can obtain by obtaining current air quality information, as obtained by the air quality parameters in weather forecast.As shown in Figure 4, the air quality parameters in some areas is over time as figure, because air quality index AQI contains the concentration value of fine particle (PM2.5) and pellet (PM10), so just current dust concentration value A indirectly can be obtained by the air quality parameters obtained as shown in Figure 4.Specifically obtain after specifically changing by air quality parameters, this can obtain with reference to existing known technology or by the experiment of limited number of time.
Because air quality index AQI reflects the concentration of the pollutant comprising PM2.5 and PM10, known by reference to AQI computational process, when PM2.5 and PM10 in air is larger, air quality index AQI is higher, such as AQI scope is from 0 to 500, is greater than the pollutant of 100 for the pollutant that exceeds standard.Such as, during the average daily concentration 35 micrograms/cubic meter of PM2.5, corresponding AQI index is the average daily concentration of 50, PM2.5 75 micrograms/cubic meter (being exactly usually said limit value), and conversion AQI index is 100; And during average daily concentration 500 micrograms/cubic meter, corresponding AQI value is 500, therefore can pre-sets an AQI by the experiment of limited number of time and comprise the roughly corresponding relation of dust concentration of PM2.5 and PM10.Such as, by monitoring the AQI index in a certain area and testing PM2.5 concentration value, corresponding relation as shown in the table can be obtained:
| AQI index | 0-20 | 20-50 | 50-90 | 90-120 | 120-150 |
| PM2.5 concentration A | 10 | 35 | 50 | 75 | 100 |
If adopt the above-mentioned mode obtaining dust concentration value A from air quality parameters, air-conditioner inside need be provided with communication module, as WIFI module.Its built-in communication module is directly connected on the webserver every preset time period ti by air-conditioner, obtains current air quality parameters, and then obtain current dust concentration value A by access Weather information associated server.Or by mobile terminal device as smart mobile phone, access Weather information associated server obtains air quality parameters, and this parameter is issued air-conditioner controller by mobile terminal device again.Corresponding dust concentration value can certainly be directly changed into and issue air-conditioner controller.Its specific implementation flow process is as follows:
Query statement is sent to an independently mobile terminal by communication module every preset time period ti;
Mobile terminal is according to command content logging in online server, and the real-time air quality parameters in access Weather information, directly sends to air-conditioner by described real-time air quality parameters or send to air-conditioner after converting dust concentration value A to;
Air-conditioner obtains dust concentration value A according to the air quality parameters received or directly receives current dust concentration value A.
Finally, the embodiment of the present invention also provides a kind of clean system for prompting of filter screen of air conditioner, and its structured flowchart as shown in Figure 5.See Fig. 5, described system comprises:
