That is, because photo detector 552b is configured along longitudinal arrangement, therefore infrared ray is taken into opening 554a left and right directions As long as width can ensure that the degree in the space (visual field) passed through to 1 incident infrared ray of photo detector 552b.

Therefore, infrared ray is taken into the opening 554a width of left and right and is configured small, it can be ensured that photo detector 552b's regards Open country simultaneously turns into the structure that finger is difficult to enter the inside that infrared ray is taken into opening 554a.

The people's detection means 55 constituted as described above drives repeatedly in the range of about 150 degree in the horizontal direction, left and right Ground changes the temperature in photo detector 552b direction, scanning room.According to its temperature detection result, judged by controlling organization The presence or absence of people and the presence direction of the people observed from air purifier.

So, because people's detection means 55 is moved in the horizontal direction, even detection zone extend along the vertical direction it is red Outside line sensor 55b, infrared ray can be also detected on a large scale in left-right direction.

Sensor motor 55c is using can adjust the stepper motor of driving angle exactly.Accordingly, it is capable to sentence exactly The presence direction of disconnected people.Stepper motor rotates angle corresponding with the umber of pulse inputted.

Sensor motor 55c is set to driving angle corresponding with input pulse number.Sensor motor For example every 1 pulsed drive α degree of 55c.That is, when being transfused to 100 pulse within every 1 second, sensor motor 55c rotations (100 × α) spend.

Pass through such structure, it is to avoid finger touches sensor holding frame 551b, therefore will not occur fingerprint stain Or sebum stain, accuracy of detection will not deteriorate.

In addition, passing through housing 55a and sensor holding frame 551b, it is to avoid directly touch live part and (refer to metal herein Wall 554b).Therefore, the possibility that the possibility that enters without finger from slit, foreign matter enter from slit, it is also not possible to from slit Insert conductor and touch live part.

So, sensor holding frame 551b carries out insulation protection to live part.It is additionally, since sensor holding frame 551b Distance with live part (referring to metallic walls 554b herein) is near, therefore people's detection means 55 will not maximize.

First, at the back side of rear body shell 12, back cover 90 is set by screw threads for fastening.Thus, up it is open 121b top forms the space K surrounded by rear body shell 12 and back cover 90.

Space K makes lower volute 12b upper opening 121b be connected with blow-off outlet 51a.Space K turns into from located at lower whirlpool The stream for the air-flow that shell 12b fan unit 20 is blown out.

Next, the installation of explanation side cover 80.

The slit for the back cover 90 that the engagement pawl 83 of side cover 80 enters the state for being installed on rear body shell 12 from side is opened Mouth 91a.Convex portion 91b insertion engagement pawl openings 83a.In this condition, side cover 80 is perpendicular to back cover 90, and covers body shell 10 side.Also, by from front is through threaded openings 64 and is threadably secured, so that side cover 80 be screwed to Preceding body shell 11.

So, engagement pawl 83 is inserted to the slit opening 91a of back cover 90, and the rear side of side cover 80 is entered back cover 90 Inner side.By the way that convex portion 91b is embedded in into engagement pawl opening 83a, so that the engaging side cover 80 in the case of without using screw etc. Rear side.The front side of side cover 80 is fixed using screw.

Thus, can reduce by side cover 80 to back cover 90 install when screw usage amount.

Next, the installation of explanation front shroud 70.

In the state of body shell 11 before air cleaning filter 60 is installed on, front shroud 70 is to cover air purification filter Body shell 11 before being installed on to the mode disassembly ease of device 60.

In the state of body shell 11 before front shroud 70 is installed on, infrared ray sensor 55b is located at sensor openings 72. Front shroud 70 be installed on before in the state of body shell 11, the screw that the threaded openings 84 of cover 80 are installed in side because of front shroud 70 from It can't see outside.

It should be noted that front shroud 70 is relative to the preceding disassembly ease of body shell 11.By pulling down front shroud 70, it can dismantle Air cleaning filter 60 and carry out the maintenance such as clean.

In addition, being formed with side recesses 82 in side cover 80.Therefore, formed in front shroud 70 and the position of side 80 pairings of cover There is gap R.Gap R turns into the air taking mouth 82a that room air is taken into the inside of air purifier.

So, left and right directions of the air taking mouth 82a towards air purifier.Therefore, from the side of air purifier It is taken into air.That is, compared with the anglec of rotation of air purifier, air taking mouth 82a direction can take from bigger scope Enter room air.

In addition, setting the dust of the amount of the dust contained by detection room air to pass in the air purifier so constituted The foul smell sensor (not shown) of the foul smell of sensor (not shown) and detection room air.

Also, these sensors are electrically connected with controlling organization.The signal that sensor is sent by detection is to controlling organization Input.Air cleaning operating can be carried out based on the signal for being input to controlling organization.

Be assembled with the air purifier in each portion as described above makes each portion act and be taken into room air and go forward side by side as described below Row air cleaning.

First, power line 41c is connected with power supply, then the detection of rotation position testing agency 45 is assembled with the state in each portion Body shell 10 (hreinafter referred to as body shell 10) and the position relationship of automatic rotary unit 40.

When body shell 10 is not towards with 40 identical direction of automatic rotary unit, i.e. body shell 10 is not towards just During face, rotary drive unit 44 is driven and body shell 10 is rotated to rotation position testing agency 45 and detect body shell Body 10 is towards untill front.

It should be noted that in this case, body shell 10 towards positive state be following states, It is located at 3 slits in separator 413a formation respectively as 3 optical choppers of rotation position testing agency 45, and all The light accepting part of optical chopper detect the state of the light for carrying out self-luminescent part.

So, in body shell 10 towards the direction of original state, i.e. towards after positive release, people's detection means 55 sensor motor 55c implements contraposition action described later, then, with infrared ray sensor 55b towards positive state Stop.

Next, by operating the operation start located at operation display part 54 to switch, controlling organization starts air cleaning and moved Make.

First, shutter motor 53 is driven, and thus shutter 52 is acted upward, and blow-off outlet 51a is opened.This When, shutter 52 is stopped to about 45 degree of direction blowout purifies the angle of air upward from horizontal direction.The blowout angle into For the best angle purified to room air.

Next, fan unit 20 is driven.Thus, indoor air is covered between 80 from formation in front shroud 70 and side Air taking mouth 82a be inhaled into the inside of air purifier.

Also, be taken into air purifier inside indoor air by front filter 61, HEPA filters 62, It is deodorized after filter 63, is sucked by the blade 23 of fan unit 20 from front, is discharged along the direction of rotation of blade 23, from blowing 51a is exported to blow out to the outside of air purifier.

Here, by operating the mode selector switch located at operation display part 54, operational mode set in advance can be selected Formula.

For example, when selection standard is operated automatically, controlling organization, which is based on people's detection means 55, dust sensor, (does not scheme Show), the testing result of foul smell sensor (not shown), act fan unit 20, automatic rotary unit 40, shutter 52.

Next, reference picture 14, Figure 15, illustrate people's detection operation of people's detection means 55.

When standard operation starts, people's detection means 55 starts the detection operation of people.Pass through sensor motor 55c's Driving, internally the housing 55a rotations provided with infrared ray sensor 55b, change infrared ray sensor 55b direction.

Sensor motor 55c turns into the setting for driving angle corresponding with input pulse number.Determine housing accordingly The amount of the 55a anglec of rotation.

It should be noted that in this case, the sensor motor 55c anglec of rotation, i.e. housing The 55a anglec of rotation is set to limit from the rotation that the rotationally constrained rib 556a of a side supports the state touched to the opposing party with framework 51 Rib 556a processed and framework 51 are supported touch untill, about 156 degree.

Reference picture 15, in step 1, controlling organization touch pulse P1 to left support of sensor motor 55c inputs, so as to pass Sensor motor 55c supports the position touched i.e. left support with framework 51 towards the rotationally constrained rib 556a in housing 55a left side and touches position Set to 0 carry out rotate counterclockwise.

The left side, which is supported, to be touched pulse P1 input pulse number and is sensor motor 55c rotate counterclockwises and makes one detection means 55 can rotate from the rotationally constrained rib 556a on right side and framework 51 support the position touched i.e. it is right support to touch position 4 and support to a left side touch position 0 Untill more than about 156 degree of the anglec of rotation umber of pulse.The stage terminated in the step 1, towards the direction of the leftmost side.

The step 1 is that controlling organization is used to sensor motor 55c rotation position is reset and can carried out infrared Line sensor 55b towards direction accurately contraposition action initial process.Thus, before step 1 beginning, even if making User's touching people detection means 55 or the contact of some objects and in the case of there occurs rotation, can also be aligned exactly Action.

Next, in step 2, controlling organization input the first correction pulse P2, so that sensor motor 55c is relative Rotation when step 1 is inverted.

First correction pulse P2 input pulse number be backlash to constituting sensor motor 55c gear or The umber of pulse for the degree that the loosening (clearance) that rotary shaft 551c is connected with housing 55a is modified.Housing 55a does not rotate and stopped Stay in the left position supported and touch position 0.

Here, the state that explanation sensor motor 55c terminates from step 1 is driven and (the step 1 that turns clockwise Reverse rotation) state.

First, the state that step 1 terminates is that the rotationally constrained rib 556a in housing 55a left side and framework 51 support the shape touched State.When inputting the first correction pulse P2, sensor motor 55c rotation drivings are with constituting sensor motor 55c's Backlash or rotary shaft the 551c amount corresponding with the loosening of housing 55a connection of gear.

Also, when the loosening disappears, sensor motor 55c rotation is transmitted to housing 55a, and housing 55a starts Turn clockwise.

Even if that is, sensor motor 55c act, due to constitute sensor motor 55c gear backlash, Or rotary shaft 551c be connected with housing 55a loosening disappear before will not transmit sensor motor 55c rotation, therefore Housing 55a does not rotate.

Therefore, housing 55a is made the state since step 1 to turn clockwise in the case of (reversion), due to reality On there is the backlash of gear or the loosening in each portion, so even to sensor motor 55c input to make housing 55a rotate The pulse of amount, housing 55a also can lingeringly start action than sensor motor 55c.

That is, due to the pulse of input, the angle of sensor motor 55c rotations is produced with the angle that housing 55a rotates Error.If being only the pulse of angle as defined in rotation, it is impossible to housing 55a is rotated accurate angle.

In order to reduce such error, in step 2, input the first correction pulse P2 and make sensor motor 55c Driving.Error thus, it is possible to reduce the anglec of rotation caused by the loosening of backlash or each portion.

Next, in step 3, controlling organization inputted to sensor motor 55c make its turn clockwise 3 degree just Beginning position setting pulse P3.Sensor motor 55c is supported from a left side and is touched position 0 to left stop position 1 and be driven.Thus, from A left side, which is supported, touches the interval that position 0 forms 3 degree to left stop position 1.

The interval is during carrying out spinning movement in left-right direction in people's detection means 55 and entering pedestrian's detection operation, For preventing housing 55a with framework 51 to the interval touched in the left stop position 1 for changing direction of rotation.

More than, step 1~step 3 is moved as the initial position setting that people's detection means 55 is entered before pedestrian's detection operation Make.By so setting the rotation initial position of people's detection means 55, can the testing result based on people's detection means 55 and make The direction of air purifier is correct.

Next, when starting people's detection, in step 4, controlling organization makes its suitable to sensor motor 55c inputs Hour hands rotate 150 degree of the pulse P4 that turns clockwise.Sensor motor 55c enters from left stop position 1 to right stop position 3 Row driving.

Here, infrared ray sensor 55b detection from detection the visual field scope object infrared ray, and by its Signal is inputted to controlling organization.Also, controlling organization is according to the input signal from infrared ray sensor 55b and has been transfused to this The sensor motor 55c of the position of signal pulse, to judge the position of people's presence.

Next, when people's detection means 55 is rotated to right stop position 3, in steps of 5, controlling organization is in order that sensing Device motor 55c is widdershins inverted and is inputted the second correction pulse P5 to sensor motor 55c.

Second correction pulse P5 input pulse number be backlash to constituting sensor motor 55c gear or The numerical value for the degree that the loosening (clearance) that person's rotary shaft 551c is connected with housing 55a is modified.

Same with the first correction pulse P2, second correction pulse P5 is used to reduce the pulse due to input and sensor drives Error between the angle of dynamic motor 55c rotations and the angle of housing 55a rotations.Second correction pulse P5 and the first correction pulse P2 is set to absolute value P2>P5.

Position 0 is touched as housing 55a and framework 51 to the state touched in left support.Supported on a left side and touch position 0, due to being along rotation After direction is pressed, therefore loosening during sensor motor 55c reversions is big.

In contrast, in right stop position 3 and the right gap touching between position 4 and have 3 degree supported.In right stop position 3, shell Body 55a is not supported with framework 51 and touched, therefore loosening during sensor motor 55c reversions is small.

Therefore, by the way that the second correction pulse P5 size to be set smaller than to the first correction pulse P2 size, Neng Goushi Local correcting said error.

Next, in step 6, controlling organization makes 150 degree of its rotate counterclockwise to sensor motor 55c inputs Anticlockwise pulse P6.Sensor motor 55c is driven from right stop position 3 to left stop position 1.

Here, infrared ray sensor 55b detection from detection the visual field scope object infrared ray, and by its Signal is inputted to controlling organization.Also, controlling organization is according to the input signal from infrared ray sensor 55b and has been transfused to this The sensor motor 55c of the position of signal pulse, to judge the position of people's presence.

Next, when people's detection means 55 is rotated to left stop position 1, in step 7, controlling organization is in order that sensing Device motor 55c is inverted and is inputted the 3rd correction pulse P7 to sensor motor 55c clockwise.

3rd correction pulse P7 input pulse number be backlash to constituting sensor motor 55c gear or The umber of pulse for the degree that the loosening (clearance) that rotary shaft 551c is connected with housing 55a is modified.

3rd correction pulse P7 is same with the first correction pulse P2, for reducing pulse due to input and sensor drive The error of the angle and the housing 55a angles rotated of dynamic motor 55c rotations.The size of 3rd correction pulse P7 absolute value and the The size of one correction pulse P2 absolute value is compared, and is set as P2>P7.

Here, being touched in left support at position 0 as housing 55a with body shell 10 to the state touched.Supported on a left side and touch position 0, After due to being the pressing on direction of rotation, therefore loosening during sensor motor 55c reversions is big.

In contrast, in left stop position 1 and the left gap touching between position 0 and have 3 degree supported.In left stop position 1, by It will not support and touch with framework 51 in housing 55a, therefore loosening during sensor motor 55c reversions is small.

Therefore, by the way that the 3rd correction pulse P7 size to be set smaller than to the first correction pulse P2 size, Neng Goushi Local correcting said error.

As previously discussed, controlling organization enters pedestrian detection device 55 in step 1~step 3 and entered before pedestrian's detection operation Initial position setting action.Controlling organization is detected with the institute of people's detection means 55 by performing step 4~step 7 repeatedly towards side To the presence or absence of corresponding people, the position that people is present will appreciate that.

Especially in addition to the sensor motor 55c of people's detection means 55 scanning motion, by making automatic return Turn the rotation of unit 40 to change the direction of body shell 10, the detection thus, it is possible to carry out larger range of people.

Also, testing result of the controlling organization based on people's detection means 55, makes the rotation driving list of automatic rotary unit 40 Member 44 and rotation position testing agency 45 drive, to make the direction just existed facing to people of air purifier.

In addition, driving shutter motor 53 and making shutter 52 towards vertical direction.Air taking mouth 82a directions are empty Gas purifier M left and right directions.Air taking mouth 82a is in 90 ° relative to the direction where people from air purifier direction Direction.Due to the direction air-supply where blowout wind direction people, therefore the dust around people efficiently can be transported to air purifier Vicinity, and blowout wind will not blow to people.
