Embodiment
The invention provides monitoring method and the device of filtering material for air purifying extent of deterioration, for making object of the present invention, technical scheme and effect clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of monitoring method of filtering material for air purifying extent of deterioration, as described in Figure 1, said method comprising the steps of:
S1, startup air purifier, gather by the first air pressure value after filter material.
Time under air purifier is in opening, gathered by the air pressure value after filter material by air pressure value harvester, the air pressure value collected is called the first air pressure value.
Because filter material in can being reacted by the air pressure value before and after filter material is to airfiltering effect, therefore in the present invention by judging by the air pressure value before and after filter material, judge its extent of deterioration, namely larger by the difference of the air pressure value before and after filter material, then illustrate that the strainability of this filter material is better, otherwise, if before and after filtering, air pressure value is unchanged, and the inefficacy of this filter material is described.
Specifically in actual applications, described air pressure value harvester can be sensor, or the harvester of other force value.
S2, the second air pressure value under the normal condition preset is deducted described first air pressure value collected, calculate the first difference between described first air pressure value and the second air pressure value.
Because the force value in air is constant, therefore calculating to be more convenient for, first by by the air pressure value before filter material, being also that the atmospheric pressure under normal condition presets, being referred to as the second air pressure value.Described second air pressure value is deducted described first air pressure value collected in above-mentioned steps, just can obtain by before and after filter material, the first difference between air pressure value.
S3, according to the first difference of calculating and the corresponding relation presetting difference range and the extent of deterioration grade arranged, the extent of deterioration grade corresponding to the difference range be in described first difference shows.
By the first difference calculated in above-mentioned steps S2, corresponding with the difference range pre-set and extent of deterioration grade, first the difference range corresponding to described first difference is found out, again that described difference range is corresponding with extent of deterioration grade, comparison goes out the extent of deterioration grade corresponding to described first difference, and extent of deterioration grade comparison gone out shows, thus the user being convenient to air purifier can monitor the extent of deterioration of described filter material in real time.
Concrete, also comprised before described step S1: the corresponding relation that difference range and extent of deterioration grade are set; Its method step is:
S00, the 3rd air pressure value after first pass filter material to be gathered.
Namely described 3rd air pressure value is filter material brand-new and when normally using, the air pressure value produced after being filtered by it.Owing to judging extent of deterioration grade, need a standard judged, therefore preferably, will be entirely brand-new filter material before and after its filtered air of use, the difference of the air pressure of generation is as the higher limit of the non-loss of a quota; Loss is complete, and use before and after its filtered air, air pressure value does not have vicissitudinous situation as lower limit, as the standard dividing extent of deterioration grade.
S01, the second air pressure value under the normal condition preset is deducted described 3rd air pressure value collected, calculate the second difference between described second air pressure value and the 3rd air pressure value.
By the second air pressure value under normal condition, also be atmospheric pressure value, deduct the 3rd air pressure value that filter material produces after filtered air under brand-new state, thus obtain the higher limit of the non-loss of a quota, the second difference is the higher limit of the non-loss of this quota.
S03, by the number of described second difference according to the extent of deterioration grade preset, on average mark off the difference range identical with loss number of levels, obtain the corresponding relation of difference range and extent of deterioration grade.
Due to the higher limit that described second difference is the quota of non-loss, and when complete loss, difference is zero, so by described second difference according to the number of the extent of deterioration grade preset to its division that is averaged, the relation one to one of difference range and extent of deterioration grade can be obtained.
Such as, the extent of deterioration grade preset is 5, and the extent of deterioration grade of filter material is divided into 5 grades, then described second difference is divided into 5 equal portions, then the corresponding loss grade of each equal portions.
The monitoring method of described filtering material for air purifying extent of deterioration, is set in advance in above-mentioned difference range and extent of deterioration grade corresponding relation in the control device of air purifier, and preserves.When needing to monitor the extent of deterioration of described filter material, then only need by by the difference range corresponding to the difference of the air pressure value before and after filter material filtered air, and the extent of deterioration grade at described difference range shows, just can know the extent of deterioration of filter material, provide users with the convenient.
After taking out at filter material or changing, be convenient to monitor its extent of deterioration, based on the above method, can also following steps be had:
Described step S1 also comprises, and is saved in history air pressure value database the second air pressure value collected and the 3rd air pressure value.
The air pressure value at every turn gathered is preserved, when after filter material change, by the air pressure value that collects after variation be saved in air pressure value in history air pressure value database and compare, if there are identical data, then illustrate that this filter material is the filter material once used, extent of deterioration judgement can be carried out by extent of deterioration grade before to it, otherwise need from the corresponding relation newly arranging difference range and extent of deterioration grade, it be carried out to the judgement of extent of deterioration.
Further, namely also comprise at described step S1, the air pressure value of preserving in the second air pressure value collected and history air pressure value database is compared, if identical, perform step S2, the difference range used before employing and extent of deterioration grade carry out the judgement of extent of deterioration grade to it, otherwise illustrate that the filter material of this use is new filter material, described second air pressure value is then needed to mate with the air pressure value in filter material database, the corresponding relation of the difference range that automatic acquisition matches with it from filter material database and extent of deterioration grade.Thus, the judgement automatically filter material being carried out to extent of deterioration grade can be realized, do not need people to be the trouble again arranged.
Preferably, the grade of extent of deterioration described in S3 is shown by LED.Concrete, the number that LED is lighted represents loss grade, such as, can represent loss grade by 5 LED, when 5 LED are entirely bright, then illustrate that this filter material is in brand-new state, non-loss; A grade has fallen in extent of deterioration, then extinguish a LED, when LED is all extinguished, then this filter material complete failure is described.
