Therefore, user's operating operation plate 5, behind the power supply opening with air purifier 1, gas sensor 10 and mobile quality testing are surveyed sensor 11 and are just begun to detect pollutant component in the air.The following describes running action based on the detection output of this two sensors 10,11.
When gas sensor 10 detected airborne gas componant, last motor 17 was actuated to drive fan 18 and rotates.And by last air entry 8, the outer air of machine is inhaled into compartment 12.At this moment, air is cleaned by micronic filter 14 and odor removal filter 15.And the air that is cleaned is discharged from last exhaust outlet 6.
The gas and the thing followed micronic dust that produce during smoking etc. are easy to swim in superjacent air space, by detecting gas componant by gas sensor 10, the air of the superjacent air space that these gas componants and the dust followed are existed is mostly inhaled to upper structure unit 25 and is purified, by this way, can efficiently they be removed.Become big if detect the speed of motor 17 in big (along with the gas concentration uprises) control of output change along with gas sensor 10, can more efficiently remove them.
In addition, survey sensor 11 1 when mobile quality testing and detect moving of human body, following motor 22 just is driven and drives fan 23 rotations.And by following air entry 9, the outer air of machine is inhaled into down compartment 13.At this moment, air is cleaned by big grain dust filter 19 and pollen private filter 20.And the air that is cleaned is from exhaust outlet 7 discharges down.
If people move, dust and the pollen saved bit by bit on the floor can waft up, so, detect moving of people by survey sensor 11 by mobile quality testing, the air of dust that will waft up and the pollen following side spaces that exist is inhaled and is purified to lower structure unit 26 more, by this way, can efficiently remove these pollen and dust.Become big (mobile frequency conversion is numerous) if survey the detection output of body sensor 11 along with mobile quality testing, the speed of following motor 22 is controlled as at a high speed, then can more efficiently remove them.
In action 1, detection signal according to gas sensor 10, and according to mobile quality testing survey sensor 11 detection signals, select to drive the motor 22 of upper structure unit motor 17 and lower structure unit respectively, but in action 2, detection signal according to gas sensor 10, compare with lower structure unit motor 22, emphasis drives upper structure unit motor 17, survey the detection signal of sensor 11 according to mobile quality testing, compare with upper structure unit motor 17, emphasis drives the motor 22 of lower structure unit.
Particularly, the action of expression in the execution graph 4.Promptly, gas sensor 10 detects rank and is set to 4 ranks (numerical value atmospheric concentration more is high more), motor 17,22 stops together about when rank is " 0 " (non-toxic gas pollutional condition in the air), rank only makes motor 17 slowly run with minimum speed when being " 1 ", rank makes motor 17 rotate with the middling speed higher than the rotating speed that slowly runs when being " 2 ", motor 22 is slowly run.Like this, the air of the superjacent air space that gas componant and the micronic dust of following exist is mostly mainly inhaled to upper structure unit 25 and is purified, and can efficiently remove them.
In addition, the situation of rank when " 3 " be, pollute disperse and be full of in whole room, up and down motor 17,22 together middling speed rotate, still, also can go up the high speed rotating of motor 17, and motor 22 rotates with middling speed down with maximum speed.
In addition, the detection rank that mobile quality testing is surveyed sensor 11 also is set at 4 ranks (the big more mobile thing of numerical value (human body) moves frequent more), rank is " 0 " (nobody, almost not mobile situation) motor 17,22 stops together about the time, rank only makes down motor 22 slowly run with minimum speed when being " 1 ", rank makes down motor 22 rotate with the middling speed higher than the rotating speed that slowly runs when being " 2 ", motor 17 is slowly run.Like this, the air of the following side space that dust that floats up from the floor because people move and pollen exist is mostly mainly inhaled to lower structure unit 26 and is purified, and can efficiently remove them.
In addition, the situation of rank when " 3 " be, dust etc. hike up disperse and are full of in whole room, up and down motor 17,22 together middling speed rotate, still, also can descend the high speed rotating of motor 22 with maximum speed, last motor 17 rotates with middling speed.
Survey the situation that sensor 11 detects gas concentration and mobile thing together at gas sensor 10 and mobile quality testing, it detects rank and turns round according to a big side.For example, it is " 2 " that gas sensor 10 detects rank, and when mobile quality testing survey sensor 11 detection ranks were " 1 ", according to gas sensor 10, middling speed was rotated and gone up motor 17, and motor 22 down slowly runs.
Survey the detection level of sensor 11 when identical at gas sensor 10 and mobile quality testing, motor 17,22 rotates with same rotational speed up and down, for example both to detect rank all be the occasion of " 2 ", motor 17,22 rotates with middling speed jointly up and down.
According to above-mentioned action 1 and action 2, can realize the effective air cleaning that various air pollutions all are fit to.
In addition, because upper structure unit 25 and lower structure unit two sections configuration in 26 fens, be used for epimere construction unit air entry 8 and exhaust outlet 6 and be used for the air entry 9 of construction unit of hypomere and exhaust outlet 7 divides up and down respectively and is arranged, so more air can be sucked from the broad space and purifies, the air that purifies is arranged to the broad space, can be improved the usefulness of air purifier.Not only can improve usefulness, can prevent that also the depth of air purifier from becoming big, and can keep the little space that is provided with.
In addition, in the foregoing description structure, because the high relatively filter of employing performance is micronic filter 14 and adopts the promptly big grain dust of the low relatively filter of performance filter 19 in lower structure unit 26 in upper structure unit 25, so can efficiently purify air.In other words, little dust etc. can be caught by the micronic filter 14 of upper structure unit 25 reliably, and big dust etc. also can be caught by the big grain dust filter 19 of lower structure unit 26 fully.Therefore but efficient allocation is used filter.In addition, compare the situation of all using micronic filter 14 in upper structure unit 25 and lower structure unit 26, can reduce micronic filter 14 quantity, reduce cost.
Above-mentioned explanation is used to explain the present invention, should not be interpreted as limiting the invention of putting down in writing in the technical scheme, perhaps reduces the scope.In addition, each several part structure of the present invention is not limited to the foregoing description, can make various distortion in the technical scope of technical scheme record.
For example, although upper structure unit 25 and lower structure unit 26 adopt filter separately respectively, also can shared same filter.At this moment, the operation panel 5 that is provided with of shell 2 central portions also can be arranged on the top or the sidepiece of shell.
Although the exhaust outlet 6,7 of upper structure unit 25 and lower structure unit 26 is divided right and left in addition, but separately also can up and down, it is not particularly limited the necessity in place, for example, also upper structure unit 25 exhaust outlets can be located at shell 2 above, the exhaust outlet of lower structure unit 26 is arranged on these two places, the left and right sides of shell 2.In addition, although the air entry 8,9 of upper structure unit 25 and lower structure unit 26 also is arranged on the front of shell 2 basically across integral body, need not limit especially, it separately also can up and down.
In addition, survey sensor 11 as mobile quality testing, although adopt current pyroelectric infrared sensor, also hyperacoustic Doppler effect of reflecting of the human body that can adopt the sonac utilization to move detects moving of people.
