Dust concentration M2b, M3b ... Mnb after M3 ... Mn and purification in gas detection air channel 112；
Step 712, not the detergent power to purifier 10 judge；
Step 714, calculates n instantaneous purifying rate d1=M1b/M1, d2=M2b/M2 ... dn=Mnb/Mn at time point；
Step 716, by n instantaneous purifying rate d1, d2 ... dn at time point, the default wink with n corresponding time point
When purifying rate g1, g2 ... gn be compared；
Step 718, works as d1>G1, d2>g2…dn>During gn, the detergent power failure of purifier is judged.
In this embodiment, according to record n time point initial room air dust concentration and purify after gas
Dust concentration in detection air channel 112 calculates corresponding instantaneous purifying rate, and by instantaneous purifying rate and corresponding default wink
When purifying rate be compared respectively, when instantaneous purifying rate is all higher than corresponding default instantaneous purifying rate, illustrate purifier
10 detergent power significantly decays, therefore, it is determined that the detergent power failure of purifier 10, realizes by instant cleaning liquid
Rate and corresponding default instantaneous purifying rate directly judge that the detergent power of purifier 10 judgement detergent power fails
Accuracy rate it is high, improve the competitiveness of product in market.Further, due to be comprehensive multiple concentration points difference after sentenced
It is disconnected so that purifier 10 judges that the accuracy rate of detergent power failure is higher, improves the user satisfaction of user.
Specific embodiment two, the VMC purifier 10 of one embodiment of the present of invention, VMC purifier
10 include two dust sensors, are separately positioned at air inlet and gas outlet, the VMC purifier 10 of the present embodiment
The schematic flow sheet of detergent power fail-ure criterion method is as shown in Figure 8：
Step 802, the powder of at least one concentration point at the air inlet 1020 of the detection purifier 10 of dust sensor 106
Dust concentration；
Step 804, judges whether the dust concentration of at least one concentration point at air inlet 1020 is dense more than default dust
Degree；When dust concentration is more than default dust concentration, into step 806；At least one concentration point at air inlet 1022
When dust concentration is less than or equal to default dust concentration, into step 808；
Step 806, dust concentration M1, M2, M3 ... Mn at Preset Time, record air inlet 1020, and gas outlet
Dust concentration M1b, M2b, M3b ... Mnb at 1022；
Step 808, not the detergent power to purifier 10 judge；
Step 810, calculates n instantaneous purifying rate d1=M1b/M1, d2=M2b/M2 ... dn=Mnb/Mn at time point；
Step 812, it is default instantaneous with n corresponding time point by n instantaneous purifying rate d1, d2, the dn at time point
Purifying rate g1, g2 ... gn are compared；
Step 814, works as d1>G1, d2>g2…dn>During gn, the detergent power failure of purifier 10 is judged.
In this embodiment, the dust concentration of the air inlet 1020 at the n time point according to record and gas outlet 1022
Dust concentration calculates corresponding instantaneous purifying rate, and instantaneous purifying rate is carried out respectively with corresponding default instantaneous purifying rate
Compare, when instantaneous purifying rate is all higher than corresponding default instantaneous purifying rate, illustrated the detergent power of purifier 10
Significantly decay, therefore, it is determined that the detergent power failure of purifier 10, realize by instantaneous purifying rate and corresponding default
Instantaneous purifying rate directly judges that the detergent power of purifier 10 accuracy rate of judgement detergent power failure is high, lifting
The competitiveness of product in market.Further, due to be comprehensive multiple concentration points difference after judged so that purifier
10 judge that the accuracy rate of detergent power failure is higher, improve the user satisfaction of user.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
