There are eight light-receiving elements (not shown) in the vertical direction, as shown in Figure 11, The object (target area) is detected in such a manner that it is divided into eight regions of different heights from A1 to A8.

The human detecting device 55 configured as described above is repeatedly driven in a range of about 150 degrees in the horizontal direction, and scans the temperature in the room, and then determines whether the presence or absence of the person is observed from the air cleaner by the temperature detecting result by the control means. The direction in which people are.

The sensor drive motor 55c uses a stepping motor that can correctly adjust the driving angle to correctly judge the direction in which the person is located. The stepping motor rotates at an angle corresponding to the number of pulses input.

The sensor drive motor 55c is set to drive an angle corresponding to the number of input pulse waves, for example, α waves are driven for each pulse wave. That is, if 100 pulse waves are input every second, the rotation is (100 × α) degrees.

The upper unit 50 having the above various parts is assembled as shown below.

The operation substrate 54a is provided on the upper surface of the segment portion 51b on the front side of the frame 51. Next, the lower operation frame 54b is provided to cover the operation substrate 54a. Then, the sheet 541c describing the description of the operation display unit 54 and the like is placed on the upper surface of the lower operation frame 54b.

In this manner, the upper surface of the operation display portion 54 of the casing 51 (the upper surface of the sheet 541c) is substantially the same as the height of the air outlet 51a, and the louver 52 is closed to cover the air outlet 51a, and the height is the same as the upper surface of the louver 52. .

In the state in which the operation substrate 54a and the lower operation frame 54b are provided to the housing 51 in this manner, the front surface concave portion 51c, the substrate concave portion 541a, and the operation frame concave portion 543b of the housing 51 are in a positional relationship in the vertical direction, and the human detecting device 55 is provided. Inside the recesses.

In the case of this embodiment, the case 55a is located in the recess of the front recess 51c. The sensor drive motor 55c is located inside the recess of the substrate recess 541a and the operation frame recess 543b. Further, the human detecting device 55 is electrically connected to a control means fixed to the casing 51 by screws.

Further, the infrared sensor 55b of the human detecting device 55 is attached to the inside of the case 55a so as to lie horizontally at a predetermined angle, and is inclined upward from the front.

The mounting angle of the infrared ray sensor 55b is set, for example, in the air cleaner M, and the infrared ray sensor 55b is placed at a position of about 80 cm from the floor surface, and is set to be θ=14° above the horizontal.

By being configured in this manner, the infrared ray sensor 55b can detect the head from a child sitting at about 1.0 [m] from the air cleaner M (sitting height 65 cm) to a standing adult (170 cm in height).

In this manner, the concave portions (51c, 541a, and 543b) are disposed in the upper unit 50 so as to be connected in the vertical direction, and the human detecting device 55 can be disposed in the space formed by the concave portions, so that the human detecting device 55 can be provided. The amount of protrusion in the direction below the upper unit 50 becomes smaller.

In other words, the air cleaning filter 60 and the human detecting device 55, which will be described later, may be configured such that the upper and lower sides do not overlap, or the amount of overlap can be made smaller, and the air installed in the direction of the person detecting device 55 can be cleanly filtered. The area of the device 60 becomes larger.

Further, in addition, the amount by which the human detecting device 55 protrudes in the direction before the upper unit 50 can be made smaller.

Next, the air cleaning filter 60 will be described with reference to Figs. 2 to 4 .

The air cleaning filter 60 is composed of a pre-filter 61 and a HEPA filter 62. And a deodorizing filter 63.

The pre-filter 61 is used to remove relatively large dust or the like from the air. The HEPA filter 62 removes dust (fine particles), bacteria, viruses, and the like which cannot be filtered by the pre-filter 61 from the air. The deodorizing filter 63 adsorbs and decomposes an odor component or a volatile organic compound (VOC) from the air flow that has passed through the pre-filter 61 and the HEPA filter 62, and removes it.

Next, a cover constituting the outer contour of the air cleaner M will be described with reference to Figs. 3 and 4 .

The outer structure of the air cleaner M is composed of a front cover 70, right and left side covers 80, and a rear cover 90.

The front cover 70 is formed in a rectangular shape that is long in the longitudinal direction, and is formed in the front side in the concave portion 71 that is long in the left and right. Further, at the left and right centers of the concave portion 71, the sensor opening 72 faced by the human detecting device 55 is opened.

The concave portion 71 is in a state where the human detecting device 55 is located at the sensor opening 72, and the concave portion provided to ensure the detection visual field of the infrared ray sensor 55b when the direction of the infrared ray sensor 55b is changed by the sensor driving motor 55c . In a state where the person detecting device 55 is located at the sensor opening 72, the front surface of the person detecting device 55 is substantially flush with the front surface of the front cover 70.

Further, the concave portion 71 is fitted to the rotation angle of the infrared ray sensor 55b, and forms a sector shape larger than about 150 degrees around the sensor opening 72. Thereby, when the person detecting device 55 operates and the case 55a rotates, the front cover 70 does not interfere with the detection field of view of the infrared sensor 55b.

Further, the sensor opening 72 is provided at a position of about 80 [cm] from the floor surface in a state where the front cover 70 is attached to the main body casing 10.

Next, the left and right side covers 80 are formed in a rectangular shape that is long in the longitudinal direction, and the armrest recessed portion 81 is formed on the side surface, and the side surface concave portion 82 having the width in the vertical direction is formed on the front side, and the engaging claws 83 that are formed toward the inner side are formed on the rear side. The engaging claws 83 are formed in a plate shape, and are opened at the inner engaging claw openings 83a. Further, on the front side, the screw opening 84 penetrating in the front-rear direction is opened.

Next, the rear cover 90 is formed in a rectangular shape that is long in the longitudinal direction, and a plurality of engagement receiving portions 91 that the engagement claws 83 are engaged with are formed on the left side and the right side. The engagement receiving portion 91 is formed by a slit-shaped opening (slit opening 91a) that faces the side and a convex portion 91b that is formed in the vicinity of the slit opening 91a and that faces the front surface of the rear cover 90. .

The front cover 70, the side cover 80, and the rear cover 90 are all configured to have the same height.

The air cleaner M is formed by assembling each of the above units and components as described below.

Referring to FIGS. 2 to 4, the fan unit 20 is provided by attaching the motor 21 to the upper concave portion 122a and the lower concave portion 122b of the rear body casing 12, respectively.

The motor 21 is attached to the upper concave portion 122a and the lower concave portion 122b so that the axial direction of the rotating shaft faces forward and downward.

That is, the fan unit 20 is disposed such that the suction port of the vane 23 faces forward, and air is taken in from the front, and the airflow is blown toward the wrap outer casings 12a and 12b which are in the radial direction of the vane 23 and are located around.

Further, the fan unit 20 is disposed in a vertical positional relationship in the vertical (vertical) direction when viewed from the front.

Next, in the rear body casing 12, the front body casing 11 is joined to cover the front face. That is, the front body casing 11 and the rear body casing 12 are aligned in front and rear, The main body casing 10 is constructed by being fixed by screws or the like.

Here, when the front body casing 11 and the rear body casing 12 are aligned and fixed in the front and rear, the bottom body casing which becomes the rotating portion of the automatic rotation unit 40 is sandwiched at the lower ends of the front body casing 11 and the rear body casing 12 42. The automatic rotation unit 40 is attached to the body casing 10.

That is, in the space where the front body casing 11 and the rear body casing 12 are aligned front and rear with the lower portion of the formed body casing 10, the bottom body casing 42 is provided to form the bottom of the body casing 10.

The bottom body casing 42 is fixed to the front body casing 11 and the rear body casing 12 in a state of being sandwiched by the front body casing 11 and the rear body casing 12. Since the bottom body casing 42 is configured to be rotatable about the base 41, the body casing 10 integrally formed with the bottom body casing 42 is configured to be rotatable to the base 41.

In this manner, when the front body casing 11 and the rear body casing 12 are aligned and fixed in the front and rear, the automatic rotating unit 40 is rotated by sandwiching the bottom body casing 42 at the lower ends of the front body casing 11 and the rear body casing 12. Mounted to the body casing 10. Therefore, the body casing 10 and the automatic rotation unit 40 can be joined (connected) more firmly. Thereby, the direction of the body casing can be changed by the rotation of the automatic rotation unit 40.

That is, the automatic rotation unit 40 rotates the main body casing 10 around the rotation axis in the vertical (vertical) direction to change the direction.

In this manner, the bottom body casing 42 is embedded in a space formed by the front body casing 11 and the rear body casing 12 being aligned in the front and rear.

That is, since the action of the bottom body casing 42 against the body casing 10 (preventing rotation) is suppressed by the shape of the space, the body is increased in weight even if the parts are attached. The outer casing 10 is rotated to firmly hold the combination of the main body casing 10 and the automatic rotating unit 40.

Further, since the fan unit 20 is placed on the heavy weight in the vertical direction, the weight can be concentrated on the position close to the center of rotation, and the rotation of the automatic rotation unit 40 can be made smooth.

Further, in a state in which the front body casing 11 and the rear body casing 12 are connected in this manner, the fan unit 20 is disposed such that the shaft of the fan motor faces forward. The suction opening of the blade 23 faces forward, the suction opening of the upper fan unit 20 faces the upper opening 111a, and the lower fan unit 20 faces the lower opening 111b.

In this manner, the fan shroud 13 and the air cleaning filter 60 are disposed as shown below before the inside of the main body casing 11 in combination with the rear body casing 12.

The fan shroud 13 is a lattice-shaped frame that prevents foreign matter from entering the inside of the fan unit 20, and is provided to cover the upper opening 111a and the lower opening 111b, respectively.

The air cleaning filter 60 is located inside the front main body casing 11, and the pre-filter 61 is disposed on the front side in this order, and the HEPA filter 62 is disposed behind the pre-filter 61 to set the deodorizing filter 63. Behind the HEPA filter 62.

Next, the upper unit 50 is provided by aligning and fixing the front body casing 11 and the rear body casing 12 to the upper portion of the body casing 10 which is formed in the front and rear. This upper unit 50 is configured to span the front body outer casing 11 and the rear main body outer casing 12. Then, the frame body 51 of the upper unit 50 is fixed to the front body casing 11 and the rear body casing 12 by screws or the like.

In this manner, since the upper unit 50 is disposed to straddle the front body casing 11 and the rear body casing 12, the frame 51 which is the skeleton of the upper unit 50 is fixed to The front body casing 11 and the rear body casing 12 are configured to more firmly form the combination of the front body casing 11 and the rear body casing 12.

That is, the connection state of the front body casing 11 and the rear body casing 12 can be reinforced without separately providing a reinforcing member that connects and fixes the front body casing 11 and the rear body casing 12. Thereby, the front body casing 11 and the rear body casing 12 can maintain a state in which the automatic rotation unit 40 is more firmly clamped.

Next, the air outlet 51a attached to the upper unit 50 of the main body casing 10 as described above is located above the upper openings 121a and 121b of the scroll casing, and is opened upward.

Further, in the sensor opening 11c of the front body casing 11, the opening for guiding the infrared rays to the inside faces forward, and the human detecting device 55 faces the state.

Here, the human detecting device 55 is provided inside the concave portion formed by the front concave portion 51c, the substrate concave portion 541a, and the operation frame concave portion 543b of the frame body 51 that is vertically connected in the vertical direction. Thereby, in a state where the person detecting device 55 is provided in the casing 51, the amount of protrusion of the person detecting device 55 to the front side and the lower side of the casing 51 can be reduced. .

In this manner, since the amount of protrusion of the person detecting device 55 to the front can be reduced, the size of the air cleaner in the front and rear directions can be made more compact.

Moreover, since the amount of protrusion of the person detecting device 55 downward can be reduced, the person detecting device 55 can be configured to have a smaller amount of shielding for the air cleaning filter 60 located below, and can make the indoor air to the air cleaning filter 60. Flow more efficiently.

Next, the position at which the substrate unit 30 is provided will be described.

Between the upper and lower directions of the upper scroll casing 12a and the lower scroll casing 12b, and the opening direction is from the upper scroll casing 12a to the back side of the upper scroll casing 12a. The substrate unit 30 is provided in the space portion 12c on the side of the space.

In this manner, by arranging the substrate unit 30 in the space portion 12c of the space formed by the spiral wraps 12a and 12b formed by the curved surface, the substrate unit 30 can be efficiently disposed, and can be formed more closely. Air cleaner.

In particular, since the space portion 12c is located between the upper scroll casing 12a and the lower scroll casing 12b, the distance between the substrate unit 30 and the fan unit 20 provided in each of the scroll casings can be made equal.

Thereby, the lengths of the wirings of the connection board unit 30 and each of the fan units 20 can be made equal, and it is not necessary to prepare a fan unit that changes the length of the wiring, and the upper and lower fan units can be attached without distinction in the assembly work.

Next, the attachment of the front cover 70, the side cover 80, and the rear cover 90 constituting the outer periphery will be described with reference to Figs. 1, 2, 3, and 4.

First, on the back surface of the rear body casing 12, the rear cover 90 is provided by screwing. Thereby, the space K surrounded by the rear body casing 12 and the rear cover 90 is formed above the upper opening 121b.

This space K connects the upper opening 121b of the lower scroll casing 12b to the air outlet 51a, and serves as a flow path from the airflow blown by the fan unit 20 provided in the lower scroll casing 12b.

Next, the mounting of the side cover 80 will be described.

The engaging claws 83 of the side cover 80 enter the slit opening 91a of the rear cover 90 in a state of being attached to the rear body casing 12 from the side, and the convex portion 91b is fitted into the engaging claw opening 83a. In this state, the side cover 80 is at right angles to the rear cover 90 and covers the side of the body casing 10. Then, the side cover 80 is fixed to the front body casing 11 with screws by passing through the threaded opening 84 from the front and fixing with screws.

In this manner, the rear side of the side cover 80 is such that the engaging claw 83 is inserted into the slit opening 91a of the rear cover 90 and enters the inner side of the rear cover 90, and the convex portion 91b is fitted into the engaging claw opening 83a, whereby it is not necessary to use Screw and other grounds are engaged, and then screwed to the front side.

Thereby, the amount of use of the screw when the side cover 80 is attached to the rear cover 90 can be reduced.

Next, the installation of the front cover 70 will be described.

The front cover 70 is attached to the front body casing 11 so as to be detachably attached to the air cleaning filter 60 in a state where the air cleaning filter 60 is attached to the front body casing 11.

In a state where the front cover 70 is attached to the front body casing 11, the infrared ray sensor 55b is located at the sensor opening 72, and the screw attached to the screw opening 84 of the side cover 80 is not visible from the outside due to the front cover 70.

Further, the front cover 70 is detachably attached to the front main body casing 11, and the air cleaning filter 60 is removed by detaching the front cover 70, and maintenance such as cleaning can be performed.

Further, since the side recessed portion 82 is formed in the side cover 80, a gap R is formed at the aligned position of the front cover 70 and the side cover 80, and this gap R serves as an air intake port 82a for taking in the air cleaner and taking in the indoor air.

In this manner, the air intake port 82a faces the left and right direction of the air cleaner, and air can be taken in from the side of the air cleaner. That is, by the rotation of the air cleaner, the indoor air can be taken in a wider range.

Further, in the air cleaner configured as described above, a dust sensor (not shown) for detecting the amount of dust contained in the indoor air and an odor sensor for detecting the odor of the indoor air are provided (not Graphic).

Moreover, the sensors are electrically connected to the control means, and the signals transmitted by the sensors are detected as input control means, and the air cleaning operation is performed based on the signals.

As shown in the above, the air cleaners that form the respective units operate as shown below, and the indoor air is taken in and the air is cleaned.

First, when the power supply line 41c is connected to the power source, the rotational position detecting means 45 detects the positional relationship between the main body casing 10 (hereinafter simply referred to as the main body casing 10) and the automatic rotation unit 40 in a state in which the respective parts are assembled.

In the case where the main body casing 10 is not oriented in the same direction as the automatic rotation unit 40, that is, in the case where the main body casing 10 is not facing the front surface, the rotational position detecting means 45 detects that the main body casing 10 faces the front surface, and the rotational driving unit 44 drives And the body casing 10 is rotated.

Further, in the case of the present embodiment, the three photointerrupters of the rotational position detecting means 45 in the state in which the main body casing 10 faces the front side are respectively located in the three slits formed in the partition plate 413a, and all the photointerrupters are provided. The light receiving unit detects the light from the light emitting unit.

In this manner, after the operation of the front surface of the main body casing 10 in the direction of the initial state is completed, the sensor drive motor 55c of the human detecting device 55 is oriented in the infrared sensor 55b after performing the alignment operation described later. The state of the front stops.

Next, by operating the operation start switch provided on the operation display unit 54, the control means starts the air cleaning operation.

First, the louver 52 is driven by the louver drive motor 53, and the louver 52 is moved upward to open the air outlet 51a. At this time, the blinds 52 are parked in the horizontal direction. The angle of the clean air is blown upwards about 45 degrees. This blowing angle is the optimum angle for making the indoor air clean.

Next, the fan unit 20 is driven. Thereby, the indoor air is taken into the interior of the air cleaner from the air intake port 82a formed between the front cover 70 and the side cover 80.

Then, the indoor air taken in from inside the air cleaner is cleaned by the pre-filter 61, the HEPA filter 62, and the deodorizing filter 63, and then sucked into the blade 23 of the fan unit 20 from the front, and The steering of the blade 23 is discharged, and is blown out to the outside of the air cleaner M from the air outlet 51a in the upward or oblique direction.

In this way, since the air outlet 51a is opened upward, the air that has become clean is blown upward or obliquely upward.

Here, the predetermined operation mode can be selected by operating the mode switching switch provided on the operation display unit 54.

For example, if the standard automatic operation is selected, the detection result of the human detecting device 55, the dust sensor (not shown), and the odor sensor (not shown) is executed by the control means to cause the fan unit 20 to automatically The operation mode in which the rotating unit 40 and the louver 52 operate.

Next, the detection operation of the person detecting means 55 by the person will be described with reference to Figs. 12 and 13 .

At the start of the standard operation, the human detecting device 55 starts the detecting action for the person. Then, the person detecting means 55 is driven by the sensor driving motor 55c, and the box 55a of the infrared ray sensor 55b is internally rotated to change the direction of the infrared ray sensor 55b.

The sensor drive motor 55c is set to drive the setting in accordance with the angle of the input pulse wave, and determines the amount of rotation of the case 55a.

Further, in the case of the present embodiment, the rotation angle of the sensor drive motor 55c, that is, the rotation angle of the case 55a is from the state in which the one rotation restricting rib 556a hits the frame 51, and the other rotation restricting rib 556a hits. To the frame 51, it is set to about 156 degrees.

Referring to Fig. 13, in STEP 1, the control means rotates to the left side of the rotation restricting rib 556a (not shown) on the left side of the case 55a toward the left hit position 0 which is a position hitting the frame 51, and the sensor is turned to the left side. The drive motor 55c inputs a left-handed collision with the pulse wave P1.

The input pulse wave number of the left-handed pulse wave P1 is turned to the left, and the human detecting device 55 is rotatable from the right-handed position 4 where the right-hand rotation restricting rib 556a hits the frame 51. The number of pulses that are about 156 degrees above the angle of rotation of the position 0 to the left. At the end of this STEP 1, the infrared sensor 55b is oriented in the leftmost direction.

This STEP 1 is a first step in which the control means resets the rotational position of the sensor drive motor 55c and can perform the correct alignment operation in the direction in which the infrared sensor 55b faces. Thereby, even before the start of STEP 1, even if the user touches the person detecting device 55 or a certain object touches and rotates, the positioning operation can be performed accurately.

Next, in STEP 2, the control means inputs the first correction pulse wave P2 in order to reverse the rotation of the sensor drive motor 55c with respect to STEP1.

The number of input pulse waves of the first correction pulse wave P2 corrects the backlash of the gear that constitutes the sensor drive motor 55c or the play of the connection between the rotary shaft 551c and the case 55a. The value of the degree, the box 55a does not rotate and stops at the position where the left side hits the position 0.

Here, a state in which the sensor drive motor 55c is driven from the state in which the STEP 1 is completed and the right turn (reverse of STEP 1) is described.

First, the state in which the STEP 1 is completed is the state in which the rotation restricting rib 556a on the left side of the case 55a hits the frame 51, and if the sensor drive motor 55c makes a right turn, the sensor drive motor 55c is rotationally driven to constitute only the sensor drive. The backlash of the gear of the motor 55c or the amount of clearance of the connection of the shaft 551c to the tank 55a.

Then, when this clearance is not present, the rotation of the sensor drive motor 55c is transmitted to the case 55a, and the case 55a starts to turn right.

That is, the case 55a is operated by the sensor drive motor 55c because the backlash of the gear constituting the sensor drive motor 55c or the clearance of the connection of the rotary shaft 551c and the case 55a does not exist even if the sensor drive motor 55c operates. The rotation will not be transmitted, so it will not rotate.

Therefore, in the case where it is desired to rotate (reverse) the case 55a in the right direction from the state of STEP 1, even if the pulse wave that is only intended to rotate the case 55a is input to the sensor drive motor 55c, since the back of the gear actually has The gap or the clearance of each part is such that the tank 55a starts to operate in a delayed manner than the sensor drive motor 55c.

That is, an error occurs in the angle at which the sensor drive motor 55c rotates according to the input pulse wave and the angle at which the tank 55a rotates. Just turning the pulse wave at a predetermined angle does not allow the case 55a to rotate correctly at a predetermined angle.

In order to reduce such an error, in STEP 2, the first correction pulse wave P2 is input, and the sensor drive motor 55c is driven to make the error of the rotation angle caused by the backlash or the clearance of each part small.

Then, in STEP3, the control means will turn right by 3 degrees. The start position setting pulse P3 is input to the sensor drive motor 55c, and is driven from the left side to the position 0 to the left stop position 1. Thereby, an interval of 3 degrees is formed from the left collision to the position 0 to the left stop position 1.

This interval is a process in which the human detecting device 55 performs a turning operation on the person in the left-right direction to change the left stop position 1 of the steering, and prevents the case 55a from colliding with the frame 51.

As described above, from STEP1 to STEP3, the start position setting operation before the human detecting device 55 performs the detecting operation for the person is performed. By setting the rotation start position of the person detecting device 55 in this manner, the air cleaner can be oriented in the correct direction based on the detection result of the person detecting device 55.

Next, at the start of the detection of the person, in STEP 4, the control means causes the right-turning pulse wave P4 rotated right by 150 degrees to be input to the sensor drive motor 55c, and is driven from the left stop position 1 to the right stop position 3.

Here, the infrared sensor 55b detects infrared rays from an object located in a range in which the field of view is detected, and inputs the signal to the control means. Then, the control means determines the position of the person from the input signal from the infrared ray sensor 55b and the pulse wave of the sensor drive motor 55c at the position where the signal is input.

Next, when the person detecting device 55 is rotated to the right stop position 3, in STEP 5, the control means inputs the second correction pulse wave P5 to the sensor drive motor 55c in order to reverse the sensor drive motor 55c to the left turn.

The number of input pulse waves of the second correction pulse wave P5 is a value that corrects the backlash of the gear of the sensor drive motor 55c or the play of the connection between the rotation shaft 551c and the tank 55a.

This second correction pulse wave P5 is the same as the first correction pulse wave P2. The error of the angle at which the sensor drive motor 55c rotates according to the input pulse wave and the angle at which the box 55a rotates is reduced, but the absolute value of the second correction pulse wave P5 and the first correction pulse wave P2 are used. The comparison of the absolute values is set to P2 > P5.

This is because the left side hits the position 0, and the box 55a hits the main body casing 10, and after the steering is pushed, the clearance when the sensor drive motor 55c is reversed is large.

In contrast, the right stop position 3 has a gap of 3 degrees between the right hit position 4, and since the case 55a does not hit the body casing 10, the clearance when the sensor drive motor 55c is reversed is small.

Therefore, by setting the magnitude of the second correction pulse wave P5 to be smaller than the magnitude of the first correction pulse wave P2, the error can be appropriately corrected.

Next, in STEP 6, the control means causes the left-turn pulse wave P6 rotated to the left by 150 degrees to be input to the sensor drive motor 55c, and is driven from the right stop position 3 to the left stop position 1.

Here, the infrared sensor 55b detects infrared rays from an object located in a range in which the field of view is detected, and inputs the signal to the control means. Then, the control means determines the position of the person from the input signal from the infrared ray sensor 55b and the pulse wave of the sensor drive motor 55c at the position where the signal is input.

Next, when the person detecting device 55 is rotated to the left stop position 1, in STEP 7, the control means inputs the third correction pulse wave P7 to the sensor drive motor 55c in order to reverse the sensor drive motor 55c to the right turn.

The number of input pulse waves of the third correction pulse wave P7 is a value that corrects the degree of the backlash of the gear of the sensor drive motor 55c or the play of the connection between the rotation shaft 551c and the tank 55a.

Similarly to the first correction pulse wave P2, the third correction pulse wave P7 is used to make the error of the angle at which the sensor drive motor 55c rotates according to the input pulse wave and the angle of rotation of the case 55a, but The comparison between the absolute value of the third correction pulse wave P7 and the absolute value of the first correction pulse wave P2 is set to P2 > P7.

This is because the left side hits the position 0, and the box 55a hits the main body casing 10, and after the steering is pushed, the clearance when the sensor drive motor 55c is reversed is large.

In contrast, the left stop position 1 is between the left collision position 0 and has a clearance of about 3 degrees, because the box 55a does not hit the body casing 10, so the clearance when the sensor drive motor 55c is reversed is small. .

Therefore, by setting the magnitude of the third correction pulse wave P7 to be smaller than the magnitude of the first correction pulse wave P2, the error can be appropriately corrected.

As described above, the control means sets the initial position setting operation before the human detecting means 55 performs the detecting operation for the person in STEP1 to STEP3, and repeats STEP4 to STEP7, thereby detecting the presence or absence of the human detecting means. The person facing the direction of the 55 is able to grasp the position of the person.

In particular, not only the scanning operation of the sensor driving motor 55c of the human detecting device 55 but also the direction of the main body casing 10 by rotating the automatic rotating unit 40 allows a wider range of detection of a person.

Further, the control means drives the rotational driving unit 44 of the automatic rotating unit 40 and the rotational position detecting means 45 in accordance with the detection result of the human detecting means 55, so that the front side of the air cleaner faces the direction in which the person is located.

Further, the louver drive motor 53 is driven to face the louver 52 in the upward direction. Because the air intake port 82a is opened in the left and right direction of the air cleaner M The mouth, so that the louver 52 will blow out the wind to the upper space in the direction in which the person is located, the flow of air is formed around the person, and the dust can be efficiently transported to the side of the air cleaner. Further, since the air is blown toward the space above the person, the blown air does not directly blow to the person.

Further, in this state, based on the detection result from the dust sensor (not shown) or the odor sensor (not shown), the fan unit 20 is raised when the indoor air dust is excessive or the odor is strong. The rotation speed of the motor 21 is reduced to the amount of dust or the intensity of the odor, and the indoor air is strongly cleaned.

Further, in this state, if the dust sensor or the odor sensor does not detect dust or odor or dirt in the room within a fixed time, or the detected value is less than or equal to a predetermined value, the human detecting device 55 is again used. Start detecting people again.
