It therefore, it can make the length of the wiring of connecting substrate unit 30 and each fan unit 20 all identical, it is not necessary to prepare Change the motor of wire length, carry out assembling operation when can not differentiate between above and below motor installed.

Below, reference picture 1, Fig. 2, Fig. 3 and Fig. 4 are to constituting the front shroud 70 of outline, covering the installation of 80 and back cover 90 sideways Illustrate.

First, it is threadably secured mode at the back side of Rear body shell 12 and back cover 90 is set.So, up open Mouth 121b top forms the space K surrounded by Rear body shell 12 and back cover 90.

The lower spiral case 12b of space K connections upper opening 121b and blow-off outlet 51a, is formed from being arranged on lower spiral case 12b Fan unit 20 blow out air-flow stream.

Below, the installation of offside mask 80 is illustrated.

The engagement pawl 83 of side cover 80 enters the back cover 90 for being in the state being arranged on Rear body shell 12 from side Slit opening 91a, convex portion 91b insertions engagement pawl opening 83a.In this condition, the relative formation of back cover 90 right angle of side cover 80, Cover the side of main body cover 10.Then, it is screwed from front by screw openings 84, so that side cover 80 is by screw thread It is fixed on front body shell 11.

So, the rear side of side cover 80 is by the way that engagement pawl 83 to be inserted to the slit opening 91a of back cover 90, into back cover 90 Inner side, convex portion 91b insertion engagement pawl opening 83a, so as to be engaged without using screw and other places, front side makes to be screwed.

So, the usage amount that side cover 80 is arranged on to screw when on back cover 90 can be reduced.

Below, the installation to front shroud 70 is illustrated.

In the state of air cleaning filter 60 is installed on front body shell 11, front shroud 70 is net to cover air The mode for changing filter 60 is removably mounted on front body shell 11.

In the state of front shroud 70 is installed on front body shell 11, infrared ray sensor 55b is opened positioned at sensor Mouth 72, externally loses the screw being installed in the screw openings 84 of side cover 80 by front shroud 70.

In addition, front shroud 70 can opposite nose main body cover 11 dismount, by pulling down front shroud 70, air purification filter can be pulled down Device 60 carries out the maintenance such as cleaning.

Further, since forming side recesses 82 on side cover 80, therefore it is combined together in front shroud 70 with side cover 80 Position form gap R, gap R turns into the air suction inlet 82a that room air is sucked inside air purifier.

So, air suction inlet 82a can also inhale towards the left and right directions of air purifier from the side of air purifier Enter air.That is, air suction inlet 82a is oriented can be from bigger scope suction chamber compared with the anglec of rotation of air purifier Interior air.

Also, the dust sensor for the amount of dust being provided with the air purifier so constituted in detection room air The foul smell sensor (not shown) of the stink of (not shown) and detection room air.

Also, these sensors are electrically connected with controlling organization, the signal for being configured to detect and send by sensor is inputted Controlling organization, can carry out air cleaning operating based on the signal.

Various pieces are assembled as described above, air purifier operates various pieces as described below, suck Interior Space Gas carries out air cleaning.

First, if power line 41c is connected with power supply, the detection of rotation position testing agency 45 assembles various pieces The position relationship of main body cover 10 (hereinafter referred to as main body cover 10) and automatic rotary unit 40 under state.

In the case where main body cover 10 and automatic rotary unit 40 be not towards equidirectional, i.e. the not court of main body cover 10 It is positive in the case of, rotary drive unit 44 is driven and rotates main body cover 10, until rotation position testing agency 45 detect main body cover 10 towards untill front.

In addition, in this case, main body cover 10 towards positive state be to be detected as rotation position Three Photo Interrupters of mechanism 45 are formed at next door 413a three slits respectively, and all Photo Interrupters are formed as light Portion detects the state for the light for carrying out self-luminescent part.

So, after main body cover 10 is positive release towards the direction of original state, people's detection means 55 Sensor motor 55c after location action described later is implemented, in infrared ray sensor 55 towards positive state It is lower to stop.

Then, by operation setting operation display part 54 operating starting switch, controlling organization start air cleaning work Industry.

First, driven by shutter board motor 53, shutter board 52 is acted upward, blow-off outlet 51a is opened.This When, shutter board 52 stops at the angle to the direction blowout purification air for playing about 45 degree upwards from horizontal direction.The blowout angle Degree turns into the best angle purified the air of a room.

Then, fan unit 20 drives.By so, room air is by from being formed between front shroud 70 and side cover 80 Air suction inlet 82a is drawn into the inside of air purifier.

Then, it is inhaled into the room air inside air purifier and passes through prefilter 61, HEPA filters 62 and deodorization Filter 63, is sucked by the blade 23 of fan unit 20 from front, the direction of rotation discharge of right backward inclined blade 23, from blow-off outlet 51a Outside to air purifier blows out.

Here, operating set in advance can be selected by operation setting in the mode selector switch of operation display part 54 Pattern.

For example when selection standard is operated automatically, based on people's detection means 55, dust sensor (not shown), foul smell sensor The testing result of (not shown), being performed by controlling organization makes the fortune that fan unit 20, automatic rotary unit 40, shutter board 52 are acted Rotary-die type.

Below, the people's detection operation of reference picture 12 and Figure 13 to people's detection means 55 is illustrated.

Once standard operation, people's detection means 55 begins to the detection operation into pedestrian.Then, people's detection means 55 By sensor motor 55c driving, the shell 55a for being internally provided with infrared ray sensor 55b is rotated, is changed Become infrared ray sensor 55b direction.

Sensor motor 55c is set to driving angle corresponding with input pulse number, correspondingly determines shell The amount of the 55a anglec of rotation.

In addition, in this case, the sensor motor 55c anglec of rotation is shell 55a rotation Angle, is set to that the rotationally constrained rib 556a for playing the opposing party from the rotationally constrained rib 556a of the side states for encountering framework 51 is touched About 156 degree untill framework 51.

Reference picture 13, in step 1, controlling organization touch pulse P1 to sensor motor 55c inputs are left so that outer Rotationally constrained rib 556a on the left of shell 55a is towards the i.e. left rotate counterclockwise of touch position 0 in position for encountering framework 51.

The input pulse number of the left touching pulse P1 is following umber of pulse：Sensor motor 55c rotate counterclockwises, make Obtaining people's detection means 55 can rotate to from the i.e. right touch position 4 in the position that the rotationally constrained rib 556a on right side encounters framework 51 More than about 156 degree of the anglec of rotation untill left touch position 0.The stage terminated in the step 1, infrared ray sensor 55b Towards the direction of the leftmost side.

The step 1 is for resetting sensor motor 55c rotation position by controlling organization so that infrared ray is passed Sensor 55b can carry out towards direction accurate location action first step.Therefore, before step 1 is started, Even in user touch remarkable detection means 55 or have contact with certain object and in the case of being rotated, can also Carry out accurate location action.

Then, in step 2, controlling organization inputs the first correction pulse P2, makes sensor motor 55c with respect to step Rotation when 1 is inverted.

First correction pulse P2 input pulse number be the gear that amendment constitutes sensor motor 55c backlash or The number of the degree for the clearance (travelling) that rotary shaft 551c is connected with shell 55a, shell 55a does not rest on left touch position rotatably 0 position.

Here, playing sensor motor 55c drivings to the state terminated from step 1 and (the step that turned clockwise Rapid 1 reverse rotation) state illustrate.

First, the state that step 1 terminates is the state that rotationally constrained rib 556a on the left of shell 55a encounters framework 51, one Denier sensor motor 55c is turned clockwise, then sensor motor 55c is to constitute sensor motor 55c The backlash of gear or the amount of rotary shaft 551c and the shell 55a clearance being connected carry out rotation driving.

Once also, the clearance disappears, then sensor motor 55c rotation is transferred to shell 55a, shell 55a Start to turn clockwise.

That is, even if sensor motor 55c is acted, the backlash of sensor motor 55c gear or rotation are being constituted Before the clearance that rotating shaft 551c is connected with shell 55a disappears, sensor motor 55c rotation is all without transmitting, therefore Shell 55a does not rotate.

Therefore, for shell 55a is from the case that the state of step 1 rotates (reversion) to the right, even if being driven to sensor Dynamic motor 55c have input the pulse of the amount of shell 55a rotations to be made, actually due to there are the backlash of gear or various pieces Clearance, shell 55a lingeringly starts action than sensor motor 55c.

That is, according to the pulse inputted, the angle that angle and the shell 55a of sensor motor 55c rotations rotate is produced Raw error.Pulse only by rotating predetermined angular can not make shell 55a rotate predetermined angular exactly.

In order to reduce such error, the first correction pulse P2 is inputted in step 2, drives sensor motor 55c It is dynamic, it is possible to reduce the error of the anglec of rotation caused by backlash or the clearance of various pieces.

Then, in step 3, controlling organization inputs the initial position for making sensor motor 55c turn clockwise 3 degree Pulse P3 is set, left stop position 1 is driven into from left touch position 0.Therefore, formed from left touch position 0 to left stop position 1 3 degree of interval.

The interval is used to prevent to enter pedestrian's detection operation with carrying out spinning movement in left and right directions in people's detection means 55 Shell 55a encounters framework 51 at the left stop position 1 for changing direction of rotation in journey.

More than, people's 55 initial position setting before pedestrian's detection operation is entered of detection means is formed from step 1 to step 3 Action.By so setting the rotation initial position of people's detection means 55, can the testing result based on people's detection means 55 just Really the direction of air purifier is oriented.

Then, once pedestrian detection is entered, then in step 4, controlling organization input makes sensor motor 55c suitable Hour hands rotate 150 degree of right rotation pulse P4, and right stop position 3 is driven into from left stop position 1.

Here, infrared ray sensor 55b detections believe this from the infrared ray for detecting object within the vision Number it is input to controlling organization.Then, controlling organization is according to the input signal from infrared ray sensor 55b and have input the signal Position sensor motor 55c pulse come judge people exist position.

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

Second correction pulse P5 input pulse number be the gear that amendment constitutes sensor motor 55c backlash or The number of the degree for the clearance (travelling) that rotary shaft 551c is connected with shell 55a.

The second correction pulse P5 is same with the first correction pulse P2, makes sensor according to the pulse inputted for reducing The error for the angle that angle and the shell 55a of motor 55c rotations rotate, but by the second correction pulse P5 absolute value with First correction pulse P2 absolute value is relatively set to P2 ＞ P5.

Because, the state that shell 55a encounters main body cover 10 is formd in left touch position 0, is to receive rotation After the pressing for turning direction, therefore, clearance when sensor motor 55c is inverted is big.

In contrast, right stop position 3 has 3 degree of space between right touch position 4, shell 55a will not hit on Main body cover 10, therefore, clearance when sensor motor 55c is inverted are small.

Therefore, by the way that the second correction pulse P5 size to be set smaller than to the first correction pulse P2 size, Ke Yizheng True ground correcting said error.

Then, in step 6, controlling organization input makes the anticlockwise of 150 degree of sensor motor 55c rotate counterclockwises Pulse P6, left stop position 1 is driven into from right stop position 3.

Here, infrared ray sensor 55b detections believe this from the infrared ray for detecting object within the vision Number it is input to controlling organization.Then, controlling organization is according to the input signal from infrared ray sensor 55b and have input the signal Position sensor motor 55c pulse judge people exist position.

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

3rd correction pulse P7 input pulse number be the gear that amendment constitutes sensor motor 55c backlash or The number of the degree for the clearance (travelling) that rotary shaft 551c is connected with shell 55a.

3rd correction pulse P7 is same with the first correction pulse P2, makes sensor according to the pulse inputted for reducing The error for the angle that angle and the shell 55a of motor 55c rotations rotate, but by the 3rd correction pulse P7 absolute value Size is relatively set to P2 ＞ P7 with the size of the first correction pulse P2 absolute value.

Because, the state that shell 55a encounters main body cover 10 is formd in left touch position 0, is to receive rotation After the pressing for turning direction, therefore, clearance when sensor motor 55c is inverted is big.

In contrast, left stop position 1 has 3 degree of space between left touch position 0, shell 55a will not hit on Main body cover 10, therefore, clearance when sensor motor 55c is inverted are small.

Therefore, by the way that the 3rd correction pulse P7 size to be set smaller than to the first correction pulse P2 size, Ke Yizheng Really correct above-mentioned error.

As described above, controlling organization is carried out in step 1 to step 3 before the executor's detection operation of people's detection means 55 Initial position setting action, by the way that step 4 is repeated to step 7, can detect whether and 55 courts of people's detection means To the corresponding people in direction, can grasp people presence position.

Especially, in addition to the sensor motor 55c of people's detection means 55 scanning motion, by making automatic rotary Turn unit 40 to rotate, thus it is possible to vary the direction of main body cover 10, so as to carry out larger range of people's detection.

Then, 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, and make the direction just existed facing to people of air purifier.

Moreover, driving shutter board motor 53, makes shutter board 52 towards vertical direction.Therefore, because air suction inlet 82a towards air purifier M left and right directions, therefore towards the direction relative to the presence of people from air purifier be 90 degree Direction, and the direction conveying blowout wind that can exist to people, therefore, it can that the dust around people effectively is transported into air cleaning By the side of device, blowout wind will not blow and beat people.

In addition, in such a state, based on the inspection from dust sensor (not shown), foul smell sensor (not shown) Result is surveyed, when dust is more in room air or when stink is strong, the rotating speed of the motor 21 of fan unit 20 is improved, to Interior Space Gas carries out Powerful purification, untill the amount of dust or the intensity decreases of smell.

Moreover, in the above-described state, if not detecting interior by dust sensor, foul smell sensor in certain time Dust or stink, or detected value be setting below, then restart the detection into pedestrian using people's detection means 55.

Industrial applicability

The present invention can be used for the air purifier for example purified the air of a room.
