Air clear The net filter 60 covers the front front cover 70, the side cover 80 covering the left and right sides, the rear cover 90 covering the front, and the components attached to these components.

The center line of the center of the turning operation of the person detecting device 55, which will be described later, disposed in the upper unit 50, is regarded as the rotation axis Ja. The center line passing through the center of the rotational motion of the automatic rotation unit 40 (the center of the rotational motion of the main body case 10) is taken as the rotation axis Jb.

The person detecting device 55 and the main body case 10 are respectively rotated to change the direction toward the horizontal direction. The rotation axis Ja and the rotation axis Jb become lines extending in the vertical direction.

The main body case 10 is configured by aligning and joining the front side front body case 11 and the rear side rear body case 12 in front and rear.

The front body case 11 is formed in a longitudinally long rectangular shape as viewed from the front. The front main body case 11 is provided with an upper partition 11a and a lower partition 11b which partition the inside into the front side and the rear side.

The upper partition plate 11a separates the upper side of the inside of the front body case 11. A circular upper opening 111a is formed in the upper partition 11a. The lower partition 11b separates the lower side of the inside of the front body case 11. A circular lower opening 111b is formed in the lower partition 11b. The upper opening 111a and the lower opening 111b are openings that penetrate in the front-rear direction. Further, the upper partition plate 11a is located in front of the lower partition plate 11b.

Further, on the front surface of the front main body case 11, the sensor opening 11c which is a position facing the human detecting device 55 to be described later is opened. This sensor opening 11c is located on the front upper side of the front body case 11, and is centered on the left and right widths.

Next, the rear main body case 12 is formed in a longitudinally long rectangular shape as viewed from the front. In the rear body case 12, the upper spiral case 12a is formed on the upper side, and the lower spiral case 12b is formed on the lower side.

These spiral cases 12a and 12b are constituted by partition walls which are formed to face forward from the front and rear wall faces 12x of the rear body case 12. The spiral shells 12a and 12b are spirally formed toward the front. Upper openings 121a and 121b that open upward are formed in the spiral shells 12a and 12b, respectively.

The upper spiral casing 12a is located in front of the lower spiral casing 12b. The space adjacent to the rear side of the upper opening 121a communicates with the upper opening 121b via the space behind the upper spiral casing 12a.

Further, between the wall surface 12x before and after the rear main body case 12 is separated from the upper spiral case 12a and the lower spiral case 12b, a space portion 12c whose opening faces the side is formed.

Further, inside the upper spiral case 12a, an upper concave portion 122a which is a circular concave portion that opens toward the front is formed. Similarly, in the inside of the lower spiral casing 12b, a recessed portion 122b which is opened toward the front and which is a circular recess is formed.

Here, the space portion 12c is located between the upper and lower spiral casings 12a and 12b. Thereby, the distance between the space portion 12c and the upper concave portion 122a and the distance between the space portion 12c and the lower concave portion 122b become equal. Or, it becomes a state of little difference.

Next, the fan unit 20 has a motor 21, a motor cover 22 that covers the motor 21, and a wing 23 that is fixed to the rotating shaft 21a of the fan 21. This fan unit 20 is driven by the motor 21, and the wings 23 are rotated, whereby air is taken in from the axial direction (front) of the rotating shaft 21a and blown out in the radial direction. This fan unit 20 is a centrifugal multi-wing fan such as a Siloco fan.

Next, the board unit 30 has a printed wiring board 31 (hereinafter referred to as a board 31) in which electronic components are assembled, a first board case 32, and a second board case 33. The first substrate case 32 houses the substrate 31 therein. The first substrate case 32 is formed of a resin. The second substrate case 33 accommodates the substrate 31 to be held inside. The first substrate case 32 in the state. The second substrate case 33 is formed of metal.

The substrate unit 30 constitutes a control means for controlling the operation of various electrical components such as a sensor or a motor constituting the air cleaner M based on an input from an operation unit or various sensors.

Further, the printed wiring board 31 of the board unit 30 may be a power source board. The microcomputer to be a control means may be provided in the operation board 54a constituting the operation display unit 54 which will be described later.

Next, the automatic rotation unit 40 will be described with reference to Figs. 5 to 7 .

The automatic rotation unit 40 has a base 41, a bottom body case 42, an automatic rotation shaft 43, a rotation drive unit 44, a rotational position detecting means 45, a slide plate 46, a slide plate fastener 47, a base side wheel 48, and a body side wheel 49. The bottom body case 42 is connected to the body case 10 and becomes a bottom. The bottom body case 42 is rotatably supported by the automatic rotating shaft 43. The rotary drive unit 44 rotates the bottom body case 42 against the base 41. The rotational position detecting means 45 detects the rotational position of the bottom body case 42.

The base 41 is a portion that supports the bottom of the entire air cleaner M. The outer shape of the base 41 is formed in a rectangular shape. In the base 41, a base recess 41a in which a circular opening is a recess is formed. In the center of the base recess 41a, a central convex portion 41b whose central portion is opened is a protruding portion. The automatic rotating shaft 43 is disposed at the center convex portion 41b.

At the center of the automatic rotating shaft 43, a through hole 43a penetrating the upper and lower sides is formed. In a state where the automatic rotating shaft 43 is attached to the center convex portion 41b, the center convex portion 41b is located inside the through hole 43a. The automatic rotating shaft 43 is attached to the base 41 by being fitted into the center convex portion 41b through a through hole 43a opening at the center of the automatic rotating shaft 43. Further, the through hole 43a communicates with the opening of the center convex portion 41b.

A power supply line 41c for obtaining electric power from the outside passes through the center convex portion 41b. The opening of the central convex portion 41b serves as an opening for guiding the power supply line 41c into the main body case. Further, the power supply line 41c is connected to the printed wiring board 31.

In this manner, the power supply line 41c is guided to the inside of the main body case 10 through the center convex portion 41b. Thereby, the main body case 10 is rotated by the automatic rotation unit 40, and the power supply line 41c is also hardly affected by the rotation.

Further, the partition plate 413a is provided in the base recessed portion 41a so as to protrude from the bottom surface. The partition plate 413a has a circular arc shape drawn at the center of the base recessed portion 41a. The three slits 414a are formed at equal intervals on the partition plate 413a. The center of the base recess 41a becomes the center of rotation of the bottom body case 42.

Further, a rack gear 415a that is fan-shaped along the opening edge is formed on the opening edge of the partition recess 41a on the opposite side of the automatic rotating shaft 43 with respect to the partition plate 413a. Further, a plurality of base side wheels 48 are provided on the opening edge of the base recess 41a. The base side wheel 48 is provided to rotate in a tangential direction of a circle drawn with the center of the base recess 41a as the origin.

Next, an opening that becomes the bearing 42a is formed at the center of the bottom body case 42. The outer shape of the bottom body case 42 is formed into a cup shape that can be inserted into the inside of the base recess 41a. A flange 42b extending from the upper end toward the outer direction is formed in the bottom body case 42. The rotational position detecting means 45, the rotational driving unit 44, the slide plate 46, and the body side wheel 49 are provided to the bottom body case 42.

In the rotational position detecting means 45, three light blockers are used. The light blocker has a light emitting portion and a light receiving portion that face each other. The light blocker is a sensor that can detect light from the light-emitting portion by the light-receiving portion. The control means determines the rotational position based on the combination of the signals when each of the three optical blockers detects light.

The three light blockers constituting the rotational position detecting means 45 are each equal in distance from the center of rotation of the bottom body case 42 (the center of the opening of the bearing 42a) to the position of the gap between the light-emitting portion and the light-receiving portion. The mode is provided in the light blocker mounting recess 42d formed in the bottom body case 42. This light blocker mounting recess 42d is a recess opened in the lower direction.

Further, the distance from the center of rotation of the bottom body case 42 (the center of the opening of the bearing 42a) to the gap between the light-emitting portion of the light blocker and the light-receiving portion is from the center of the automatic rotating shaft 43 provided at the base 41. The distance to the partition 413a is equal. The interval between the centers of the adjacent photo blockers is equal to the interval formed between the adjacent slits of the spacer 413a.

Further, the gap between the light-emitting portion and the light-receiving portion of the light blocker is configured to be open in the downward direction.

Here, the center of rotation of the bottom body case 42 (the center of the opening of the bearing 42a) becomes the rotation axis Jb. That is, the rotation axis Jb is a virtual line passing through the center of the rotation operation of the automatic rotation unit 40 (the center of the rotation operation of the main body case 10). The body case 10 is rotated to change the direction toward the horizontal direction. The rotation axis Jb becomes a line extending in the vertical direction.

Next, the rotary drive unit 44 has a stepping motor 44a serving as a drive source, a pinion 44b, a bearing holding plate 44c, and a motor case 44d. The pinion gear 44b is attached to the rotating shaft 441a of the stepping motor 44a. The bearing holding plate 44c receives the rotating shaft 441a of the stepping motor 44a. The motor case 44d covers and holds the stepping motor 44a from the lower side.

The rotation driving unit 44 configured in this manner is in a state in which the rotating shaft 441a faces downward, and is formed in the motor case 44d and the bearing holding plate. The screw hole of the 44c is screwed from the lower side of the bottom body case 42. By mounting the rotary drive unit 44 in this manner, the pinion 44b is located below the bottom body case 42.

Next, the slide plate 46 is formed in a ring shape in which the slide plate opening 46a is formed inside the circular plate. A flange recess 46b into which the flange 42b enters is formed on the upper surface of the slide plate 46.

The slide plate 46 formed in this manner is fixed to the bottom body case 42 by screws or the like in a state where the slide plate opening 46a passes through the bottom body case 42 and the flange 42b enters the flange recess 46b.

Then, the main body side wheel 49 is rotatably mounted in the wheel housing 42c in a state in which one of the main body side wheels 49 protrudes from the bottom main body case 42 to the lower side, and the wheel case 42c is formed under the bottom main body case 42 and is under a recess that is oriented in the direction.

Further, a plurality of body side wheels 49 are attached to the bottom body case 42. Each of the body side wheels 49 is disposed to be equal to the center of rotation of the bottom body case 42 (the center of the opening of the bearing 42a).

Each of the above-described automatic rotation units 40 is assembled as shown below.

The bearing 42a is mounted to be rotatably supported by the automatic rotating shaft 43 attached to the base 41. Thereby, the bottom body case 42 in which the respective portions are provided as described above is attached to the base 41.

At this time, the pinion 44b provided in the rotary drive unit 44 of the bottom body case 42 is in a state of meshing with the rack gear 415a provided on the base 41. Further, the partition plate 413a is located in a gap between the opposite light-emitting portion and the light-receiving portion of the rotational position detecting means 45.

Further, in order to prevent the bearing 42a from coming off the automatic rotating shaft 43, A stopper 42e is attached. The stopper 42e is engaged with the groove portion 431a formed on the side surface of the automatic rotating shaft 43 from the side opening 421a of the bearing 42a, and is prevented from coming off in the upper direction.

Further, by attaching the slide plate suppressing member 47 that restrains the peripheral edge of the slide plate 46 from above to the base 41, it is possible to suppress the rattling when the bottom main body case 42 is rotated.

In this manner, in a state where the bottom body case 42 is attached to the base 41, the body side wheel 49 comes into contact with the base 41 and supports the bottom body case 42. Further, the base side wheel 48 is in contact with the slide plate 46 and supports the bottom body case 42.

These wheels are rolled by rotating the base body 42 toward the base 41, reducing the resistance between the two members. Thereby, the side of the bottom body case 42 is smoothly rotated.

Further, the distance from the center of rotation of the bottom main body case 42 (the center of the opening of the bearing 42a) to the gap between the light-emitting portion of the light blocker and the light-receiving portion is the center from the automatic rotating shaft 43 provided at the base 41. The distance to the partition 413a is equal. Therefore, the bottom main body case 42 is rotatable in a state where the partition plate 413a is located between the light emitting portion and the light receiving portion.

Therefore, in a state where the base 41 is placed on the floor surface, the stepping motor 44a operates to rotate the pinion gear 44b that meshes with the rack gear 415a, and the bottom body case 42 rotates against the base 41.

When the bottom main body case 42 is rotated and the direction is changed in this manner, the light blocker of the rotational position detecting means 45 rotates together with the bottom main body case 42 in a state in which the light-emitting portion and the light-receiving portion are sandwiched by the partition plate 413a.

Further, by the rotation, the position of the rotational position detecting means 45 and the partition 413a is changed. According to the rotational position, the slit 414a is located between the light-emitting portion and the light-receiving portion, and the light-receiving portion detects light from the light-emitting portion.

The control means determines the rotational position (direction) of the bottom body case 42 (the body case 10) based on a combination of the states detected by the light receiving portions of the respective light blockers.

Next, the upper unit 50 will be described with reference to Figs. 1 to 2 and Fig. 8.

The frame body 51 is a segment portion 51b that is lower than the peripheral edge of the air outlet 51a than the front side of the air outlet 51a. A front recess 51c that is recessed toward the rear is formed in front of the frame 51. A person detecting device 55 to be described later is provided in the front concave portion 51c.

Next, the louver 52 changes the direction of the cleaned air blown from the air outlet 51a. The two louvers 52 are disposed to straddle the left and right of the air outlet 51a so as to be aligned in the front and rear. The louver 52 is rotatably supported by the inner wall of the left and right blown outlets 51a.

In the casing 551a, the opening 553a toward the lower opening, the infrared absorbing opening 554a opening toward the front, the shaft connecting portion 555a to which the rotating shaft 551c of the sensor driving motor 55c is connected, and the rotation limit of the rotation angle of the restriction box 55a are formed. Rib 556a.

The rotation restricting ribs 556a are formed so as to protrude from the shaft connecting portion 555a in the left-right direction. The rotation limiting rib 556a is attached to the sensor drive When the movable motor 55c rotates the case 55a, the frame 51 of the portion to be mounted by the person detecting device 55 is hit, and the rotation angle of the case 55a is restricted.

Further, the position at which the left rotation restricting rib 556a hits the frame 51 corresponds to a leftward hit position 0 which will be described later. The position where the rotation restricting rib 556a on the right side hits the frame 51 corresponds to the right hit position 4.

In the inside of the case 55a formed in this manner, the infrared sensor 55b is inserted in a state of being held by the sensor holding frame 551b. The lower opening 553a is closed by a cover 552a.

The portion of the sensor holding frame 551b opposed to the infrared ray input opening 554a is constituted by a member that transmits infrared rays. In this state, the infrared ray sensor 55b is configured to detect infrared rays incident on the infrared ray opening 554a of the tank 55a.

The sensor drive motor 55c drives the case 55a to change the direction of the infrared sensor 55b. The sensor drive motor 55c uses a stepping motor. The sensor drive motor 55c is connected to the shaft connection portion 555a formed on the upper portion of the case 55a such that the rotation shaft 551c is vertically downward. Here, the center line of the rotating shaft 551c becomes the rotation axis Ja. The person detecting device 55 is rotated to change the direction toward the horizontal direction. The rotation axis Ja becomes a line extending in the vertical direction.

Further, in the present embodiment, since the tank 55a is directly connected to the sensor drive motor 55c, the rotation axis Ja coincides with the rotation shaft 551c.

The person detecting device 55 fixed in this manner has a shape in which the box 55a holding the infrared sensor 55b and the sensor driving motor 55c are vertically connected in the vertical direction.

The person detecting device 55 constructed in this manner is driven by the sensor driving motor 55c, and the direction of the box 55a is changed, and the side of the infrared sensor 55b is changed. Change to. The direction of the infrared ray sensor 55b is configured to be rotationally drivable in an angular range of about 150 degrees in the horizontal direction.

Referring to Fig. 12, the angle of the infrared sensor 55b from the left stop position 1 to the right stop position 3 is set to 150°. The angle of the infrared sensor 55b from the left side to the position 0 to the left stop position 1 and the angle from the right side to the position 4 to the right stop position 3 are set at 3 degrees. Thereby, the infrared sensor 55b is configured not to be rotated beyond an angle 156° from the left collision to the position 0 to the right collision to the position 4.

Further, the infrared sensor 55b detects infrared rays from the object. In the longitudinal direction, eight light-receiving elements (not shown) are provided, and as shown in FIG. 11, the object (target area) can be detected so as to be divided into eight regions having different heights from A1 to A8.

The human detecting device 55 configured as described above is repeatedly driven in a range of 150° in the horizontal direction to scan the temperature in the room. From the temperature detection result, it is determined by the control means that there is a direction in which no one is observed by the person observed from the air cleaner M.

The sensor drive motor 55c uses a stepping motor that can correctly adjust the driving angle. Thereby, the direction in which the person exists can be correctly judged. The stepping motor rotates at an angle corresponding to the number of pulses input.

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

The upper unit 50 having the above respective portions is assembled as follows.

The operation substrate 54a is provided on the upper surface of the segment portion 51b on the front side of the casing 51. Next, the lower operation frame 54b is provided to cover the operation substrate 54a. then, The upper operation frame 54c is placed on the upper side of the lower operation frame 54b.

The upper surface of the operation display portion 54 provided in the casing 51 in this manner is located at substantially the same height as the air outlet 51a. The upper surface of the operation display portion 54 is in a state in which the louver 52 is closed and covers the air outlet 51a, and the height coincides with 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. The person detecting device 55 is disposed inside the recess of these members.

In the case of this embodiment, the case 55a is located inside 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 fixed to the casing 51 by screws, and is electrically connected to the control means.

Further, the infrared sensor 55b of the human detecting device 55 is attached to the inside of the case 55a so as to be inclined at a predetermined angle in the vertical direction, 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, when the infrared ray sensor 55b is placed at a height of about 80 cm from the floor surface, and is set to be θ=14° above the level.

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

In this manner, each of the recesses (51c, 541a, 541b) is disposed in the upper unit 50 so as to be connected in the vertical direction. The person detecting device 55 is disposed in a space formed by the recesses. Thereby, the person detecting device 55 is below the upper unit 50. The amount that the party stands out becomes less.

In other words, the air cleaning filter 60 to be described later and the human detecting device 55 do not overlap each other in the vertical direction, or the amount of overlap can be reduced. Further, the area in which the air cleaning filter 60 installed in the downward direction of the person detecting device 55 is provided can be made larger.

Further, in addition to this, the amount by which the person detecting device 55 protrudes in the front direction of the upper unit 50 becomes 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, 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 that cannot be removed by the pre-filter 61 from the air. The deodorizing filter 63 adsorbs, decomposes, and removes odorous components or volatile organic compounds (VOC) from the air flow that has passed through the pre-filter 61 and the HEPA filter 62.

Next, referring to Fig. 4, a cover constituting the outer contour of the air cleaner M will be described.

The outer contour 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. A recess 71 on the left and right length is formed on the front surface of the front cover 70. 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 in the sensor opening 72, and the concave portion is provided to ensure the detection field of the infrared sensor 55b when the direction of the infrared sensor 55b is changed by the sensor driving motor 55c. . In a state where the person detecting device 55 is located in the sensor opening 72, the front surface of the person detecting device 55 is substantially the same surface as 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 to form a fan shape larger than about 150° 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 the infrared rays.

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 case 10.

Next, the left and right side covers 80 are formed in a longitudinally long rectangular shape. The armrest recess 81 is formed on the side of the side cover 80. A side recess 82 having a width in the up and down direction is formed on the front side of the side cover 80. Engagement claws 83 that stand toward the inner side are formed at the rear side of the side cover 80. The engaging claws 83 are formed in a plate shape. The engaging claw opening 83a is opened inside the engaging claw 83. Further, the screw opening 84 penetrating in the front-rear direction is opened at the front side.

Next, the rear cover 90 is formed in a rectangular shape that is long in the longitudinal direction. On the left side and the right side of the rear cover 90, an engagement receiving portion 91 in which a plurality of engaging claws 83 are engaged is formed. The engagement receiving portion 91 is formed by a slit-shaped opening (slit opening 91a) facing the side and a convex portion 91b formed in the vicinity of the rear cover 90 and in the vicinity of the slit opening 91a.

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

Each of the above units and components is assembled as shown below to form an air cleaner M.

Referring to FIGS. 2 to 4, the motor 21 is attached to the upper concave portion 122a and the lower concave portion 122b of the rear main body case 12, and is provided in the fan unit 20.

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

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

Next, the front body case 12 is connected to the front body case 12 so as to cover the front side. That is, the front main body case 11 and the rear main body case 12 are aligned in front and rear, and are fixed by screwing or the like to constitute the main body case 10.

Here, when the front body case 11 and the rear body case 12 are aligned in front and rear and fixed, the automatic rotating unit 40 is rotated by sandwiching the bottom body case 42 at the lower ends of the front body case 11 and the rear body case 12. Installed in the body box 10.

That is, the bottom main body case 42 is provided in the space in which the front main body case 11 and the rear main body case 12 are aligned front and rear with the lower portion of the formed main body case 10, and the bottom of the main body case 10 is formed.

The bottom main body case 42 is fixed to the front main body case 11 and the rear main body case 12 while being sandwiched by the front main body case 11 and the rear main body case 12. The bottom body case 42 is configured to be rotatable about the base 41. Therefore, the body case 10 which is integral with the bottom body case 42 is configured to be rotatable to the base 41.

In this manner, when the front body case 11 and the rear body case 12 are aligned in front and rear and fixed, the automatic body unit is rotated by sandwiching the bottom body case 42 at the lower ends of the front body case 11 and the rear body case 12. 40 is mounted to the main body case 10. Thereby, the main body case 10 can be firmly coupled with the automatic rotation unit 40.

In particular, the bottom body case 42 is embedded in a space formed by front and rear alignment of the front body case 11 and the rear body case 12.

That is, the shape of the space suppresses the action of the bottom body case 42 on the body case 10 (to prevent rotation). Therefore, even if the weight of the main body case 10 is rotated by being mounted, the combination of the main body case 10 and the automatic rotation unit 40 can be firmly maintained.

Further, in a state in which the front main body case 11 and the rear main body case 12 are connected in this manner, since the fan unit 20 is disposed such that the rotating shaft 21a faces forward, the suction opening of the wing 23 faces forward. The suction opening of the fan unit 20 on the upper side faces the upper opening 111a, and the fan unit 20 on the lower side faces the lower opening 111b.

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

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

The air cleaning filter 60 is disposed inside the front body case 11. The air cleaning filter 60 sequentially sets the pre-filter 61 on the front side, the HEPA filter 62 in the rear of the pre-filter 61, and the deodorizing filter 63 in the rear of the HEPA filter 62.

Next, the upper unit 50 is provided on the upper portion of the main body case 10 which is formed by the front main body case 11 and the rear main body case 12 aligned and fixed. This upper unit 50 is configured to span the front body case 11 and the rear body case 12. Further, the frame body 51 of the upper unit 50 is fixed to the front body case 11 and the rear body case 12 by screwing or the like.

In this manner, the upper unit 50 is disposed to straddle the front body case 11 and the rear body case 12, and the frame 51 which is the skeleton of the upper unit 50 is fixed to the front body case 11 and the rear body case 12. Therefore, the combination of the front body case 11 and the rear body case 12 becomes stronger.

Next, the air outlet 51a attached to the upper unit 50 of the main body case 10 as described above is located above the upper openings 121a and 121b of the spiral case. Further, in the sensor opening 11c of the front main body case 11, the opening that guides the infrared rays to the inside faces forward, and the human detecting device 55 faces the state.

Here, the person 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 which is vertically connected in the vertical direction. Thereby, in the state in which the human detecting device 55 is provided in the casing 51, the amount of protrusion of the human detecting device 55 to the front and the lower side of the casing 51 can be reduced.

In this way, the amount of protrusion of the human detecting device 55 to the front is reduced. Thereby, the size of the air cleaner M in the front and rear directions can be formed smaller.

Further, the amount of protrusion of the person detecting device 55 downward is reduced. Therefore, it can be configured such that the amount by which the human detecting device 55 shields the air cleaning filter 60 located below becomes smaller. Thereby, the indoor air can be made to flow to the air cleaning filter 60 more efficiently.

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

The substrate unit 30 is provided between the upper and lower sides of the upper spiral case 12a and the lower spiral case 12b, and the opening from the upper spiral case 12b to the space on the back side of the upper spiral case 12a faces the side space portion 12c.

The space portion 12c is a space formed by a difference in the shape of the spiral case 12a, 12b formed by the curved surface and the shape of the main body case 12 after the rectangle. By providing the substrate unit 30 in the space portion 12c, the substrate unit 30 can be efficiently disposed, whereby the air cleaner M can be formed smaller.

In particular, the space portion 12c is located in the upper spiral casing 12a and the lower spiral casing Between 12b. Therefore, the distance from the board unit 30 of the fan unit 20 provided in each spiral case 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. Therefore, it is not necessary to prepare a motor for changing the length of the wiring, and the upper and lower motors 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. 3 and 4 .

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

This space K is such that the upper opening 121b of the lower spiral case 12b communicates with the air outlet 51a. This space K serves as a flow path from the airflow blown by the fan unit 20 provided in the lower spiral casing 12b.

Next, the installation 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 main body case 12 from the side. The convex portion 91b is fitted into the engagement 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 case 10. Further, the side cover 80 is fixed to the front body case 11 by screws by screwing the screw from the front through the screw opening 64.

In this manner, the rear side of the side cover 80 enters the inner side of the rear cover 90 after the engaging claw 83 is inserted into the slit opening 91a of the rear cover 90. The rear side of the side cover 80 is fitted into the engaging claw opening 83a by the convex portion 91b, and is engaged without using a screw or the like. The front side of the side cover 80 is fixed by screws.

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 main body case 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 main body case 11.

In a state where the front cover 70 is attached to the front body case 11, the infrared sensor 55b is located at the sensor opening 72. In a state where the front cover 70 is attached to the front body case 11, the screws attached to the screw openings 84 of the side cover 80 are not visible from the outside by the front cover 70.

Further, the front cover 70 is detachable from the front main body case 11, and the air cleaning filter 60 is removed by removing 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. This gap R serves as an air intake port 82a for taking in indoor air into the air cleaner M.

In this manner, the air intake port 82a faces the left and right direction of the air cleaner M, and air is also taken in from the side of the air cleaner M. That is, the air intake port 82a is oriented so as to take in indoor air from a range wider than the rotation angle of the air cleaner M.

Further, the air cleaner M configured in this manner is provided with 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 ( Not shown).

Moreover, the sensors are electrically connected to the control means, and the sensor detects the signal generated by the sensor as an input control means, and is configured to perform an air cleaning operation based on the signal.

Furthermore, as shown in Fig. 1 and Fig. 2, the air in the group is cleared. In the state in which the main unit 10 is stopped in the front direction, the rotation axis Ja and the rotation axis Jb are in a positional relationship overlapping when the main body is viewed from the front, and are located substantially at the center of the width of the main body case 10. Further, the rotation axis Ja is located further forward than the rotation axis Jb.

As shown in the above, the air cleaner M that assembles each unit is operated as follows, 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 case 10 (hereinafter simply referred to as the main body case 10) and the automatic rotation unit 40 in a state in which the respective parts are assembled.

In the case where the main body case 10 is not facing the same direction as the automatic rotation unit 40, that is, when the main body case 10 is not facing the front side, the rotational position detecting means 45 detects that the main body case 10 faces the front side, and the rotary drive unit 44 drives, so that The body box 10 is rotated.

Further, in the case of the present embodiment, in the state in which the main body case 10 faces the front side, the three light blockers of the rotational position detecting means 45 are respectively located in the three slits formed in the partition plate 413a, and all the light is blocked. The device becomes a state in which 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 case 10 in the direction of the initial state is completed, the sensor drive motor 55c of the person detecting device 55 is placed in the infrared sensor 55b after performing the position alignment operation described later. Stops toward the front.

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

First, driven by the louver drive motor 53, the louver 52 is in the upward direction The operation opens the air outlet 51a. At this time, the louver 52 is stopped at an angle at which the clean air is blown in a direction from the horizontal direction by 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 M 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 M passes through the pre-filter 61, the HEPA filter 62, and the deodorizing filter 63, and is sucked into the wing 23 of the fan unit 20 from the front, and is in the wing 23 The steering is discharged, and is blown out from the air outlet 51a to the outside of the air cleaner M.

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 fan unit 20 is automatically rotated by the control means based on the detection results of the human detecting device 55, the dust sensor (not shown), and the odor sensor (not shown). The operation of unit 40 and louver 52 operates.

Next, the human detecting operation of the person detecting device 55 will be described with reference to Figs. 12 and 13 .

At the start of the standard operation, the human detecting device 55 starts the human detecting operation. Driven by the sensor drive motor 55c, the case 55a in which the infrared sensor 55b is disposed is rotated, and the direction of the infrared sensor 55b is changed.

The sensor drive motor 55c is set to drive the angle corresponding to the input pulse wave number, and accordingly, the amount of the rotation angle of the case 55a is fixed.

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 encountered from one of the rotation restricting ribs 556a. In the state of the frame 51, the other rotation restricting rib 556a hits the frame 51 and is set to about 156°.

Referring to Fig. 13, in STEP 1, the control means is such that the rotation restricting rib 556a of the sensor drive motor 55c is turned to the left side of the case 55a by the left turn toward the position where it hits the frame 51, and the position is 0. The sensor drive motor 55c inputs a left-handed collision to the pulse wave P1.

The input pulse wave number of the left-handed pulse wave P1 is turned to the left, and the right side hits the position 4 from the position where the right rotation restricting rib 556a hits the frame 51, and can be rotated to the left side. The number of pulses to the position 0 is about 156° or more. At the end of this STEP1, it is towards the leftmost direction.

This STEP 1 is used to create a control means for resetting the rotational position of the sensor drive motor 55c, and to perform the first step of correct alignment operation in the direction in which the infrared sensor 55b is directed. Thereby, even before the start of STEP 1, even when the user touches the human detecting device 55 or an object to rotate, the positioning operation can be performed correctly.

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 is an amount correcting the backlash of the gear of the sensor drive motor 55c or the gap (play) between the rotation shaft 551c and the tank 55a, and the tank 55a does not rotate. And stay in the left position to hit position 0.

Here, a state in which the state sensor drive motor 55c that is completed by STEP 1 is driven to perform a right turn (reverse of STEP 1) will be 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. When the first correction pulse wave P2 is input, the sensor drive The motor 55c drives an amount of rotation that only rotates the backlash of the gear of the sensor drive motor 55c or the connection of the shaft 551c to the tank 55a.

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

That is, the case 55a does not transmit the sensor drive motor 55c because the backlash of the gear constituting the sensor drive motor 55c or the gap 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, so do not turn.

Therefore, when 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 required to rotate the case 55a is input to the sensor drive motor 55c, since there is actually a gear The backlash or the gap between the respective portions 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 accordance with the angle at which the pulse wave sensor driving motor 55c is rotated and the angle at which the box 55a is rotated, and the box 55a cannot be rotated by a correct angle only by the pulse wave of the 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. Thereby, the error of the rotation angle caused by the backlash or the gap of each part can be made small.

Next, in STEP 3, the control means inputs a pulse wave P3 which is set to the home position where the sensor drive motor 55c is turned right by 3°. The sensor drive motor 55c is driven from the left collision to the position 0 to the left stop position 1. Thereby, an interval of 3° is formed from the left collision to the position 0 to the left stop position 1.

This interval is a process of performing a human detecting operation in the case where the human detecting device 55 performs a turning operation in the left-right direction, and changes the left stop position 1 of the steering. The case 55a is prevented from hitting the frame 51.

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

Next, at the start of the human detection operation, in STEP 4, the control means inputs the right-turn pulse wave P4 which is rotated right by 150° into the sensor drive motor 55c. The sensor drive motor 55c 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 the range of the detection field of view, and inputs the signal to the control means. Then, the control means determines the position where the person exists 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 switches the sensor drive motor 55c to the left turn, and the second correction pulse wave P5 is input to the sensor drive motor 55c.

The number of input pulse waves of the second correction pulse wave P5 is an amount correcting the backlash of the gear of the sensor drive motor 55c or the gap (play) between the rotation shaft 551c and the tank 55a.

The second correction pulse wave P5 is similar to the first correction pulse wave P2 in that an error in the angle of rotation of the input pulse wave sensor drive motor 55c and the angle of rotation of the case 55a is made small. The comparison between the absolute value of the second correction pulse wave P5 and the absolute value of the first correction pulse wave P2 is set to P2 > P5.

When the left side hits the position 0, the box 55a hits the frame 51. It hits position 0 on the left because it is after the steering is pushed, so the sensor drive motor 55c The gap is large when reversing.

In contrast, the right stop position 3 is between the right hit position 4 and has a gap of 3°. In the right stop position 3, since the case 55a does not hit the frame 51, the gap 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 above error can be appropriately corrected.

Next, at STEP 6, the control means inputs the left-turn pulse P6 which is turned left by 150° into the sensor drive motor 55c. The sensor drive motor 55c 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 the range of the detection field of view, and inputs the signal to the control means. Then, the control means determines the position where the person exists 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 an amount that corrects the backlash of the gear of the sensor drive motor 55c or the gap (play) between the rotation shaft 551c and the tank 55a.

The third correction pulse wave P7 is similar to the first correction pulse wave P2 in that the angle between the angle of rotation of the input pulse wave sensor drive motor 55c and the angle of rotation of the case 55a is made small. 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.

When the left side hits the position 0, the box 55a hits the frame 51. Hit left When the position is 0, since the steering is pushed, the gap when the sensor drive motor 55c is reversed is large.

In contrast, the left stop position 1 is between the right and the right position 4, with a gap of 3°. In the left stop position 1, since the case 55a does not hit the frame 51, the gap 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 above error can be appropriately corrected.

As described above, the control means performs the home position setting operation before the human detecting device 55 performs the human detecting operation in STEP1 to STEP3. The control means detects the presence or absence of a person corresponding to the direction in which the person detecting means 55 is directed by repeating STEPs 4 to STEP 7, and can grasp the position where the person exists.

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 case 10 is changed by the rotation of the automatic rotating unit 40, whereby the detection of a wider range of people can be realized.

Then, the control means drives the rotational driving unit 44 of the automatic rotating unit 40 and the rotational position detecting means 45 based on the detection result of the human detecting means 55, so that the front side of the air cleaner M faces the direction in which the person exists.

Further, the louver drive motor 53 is driven to face the louver 52 in the vertical direction. Since the air intake port 82a faces the left-right direction of the air cleaner M, the air cleaner M is oriented in a direction of 90° to the direction in which the person is present. Therefore, since the blown air can be sent in the direction in which the person is located, the dust around the person can be efficiently transported to the vicinity of the air cleaner M, and the blown air does not blow to the person.

Moreover, in this state, based on the detection result from the dust sensor (not shown) and the odor sensor (not shown), when the dust of the indoor air is excessive or stinky When the taste is strong, the number of revolutions of the motor 21 of the fan unit 20 is increased, and the amount of dust or the intensity of the odor is lowered, and the indoor air is strongly cleaned.

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

Fig. 14 is a view showing an image of the rotation angle of the human detecting device corresponding to the indoor divided region. As shown in Fig. 14, the indoor areas on the front side of the air cleaner M are classified into five directions of "left", "left middle", "central", "right middle", and "right". By repeating the above-described STEPs 4 to STEP 7, the presence or absence of a person corresponding to the direction in which the human detecting device 55 is directed is detected, and it is determined which direction is in the divided indoor region. For example, in the operation range of the person detecting device 55, five divisions are performed centering on the rotation axis Ja, and a person is detected in the operation range A, and it is determined that the indoor area is "left".

Here, in a state where the main body case 10 is stopped in the front direction, the rotation axis Ja and the rotation axis Jb located at the center of the width of the main body case 10 are in a positional relationship that overlaps when the main body is viewed from the front. Therefore, the operating range A to E of the human detecting device 55 can be a bilaterally symmetrical angle. Here, the left-right symmetry means that A and E, B and D are respectively the same angle. Therefore, the decision control system is simple and the direction of the correct person can be detected.

For example, as shown in Fig. 15, when the rotational axis Ja and the rotational axis Jb do not have a positional relationship that overlaps when the main body is viewed from the front, the operational ranges A to E of the human detecting device 55 do not become bilaterally symmetrical. Therefore, the operation ranges A to E of the human detecting device 55 need to be separately set, and the determination control becomes complicated.

Here, Fig. 16(a) is a view showing the main unit 10 facing the indoor area "left". Fig. 16(b) is a view showing the main unit 10 facing the indoor area "right". When the human detecting device 55 performs the human detecting operation at the position of Fig. 16(a), the indoor regions "left", "left center", and "center" correspond to the operating ranges C, D, and E of the human detecting device 55. Similarly, when the human detecting device 55 performs the human detecting operation at the position of FIG. 16(b), the indoor regions "center", "right center", and "right" correspond to the operating ranges A, B of the human detecting device 55, C.

In this manner, in a state in which the main body case 10 is stopped in the front direction, since the rotation axis Ja and the rotation axis Jb located at the center of the width of the main body case 10 are in a positional relationship overlapping when the body is viewed from the front, the 16(a) and 16(b), the operating ranges A to E of the human detecting device 55 can be bilaterally symmetrical. Therefore, the decision control system is simple and the direction of the correct person can be detected.

As shown above, the air cleaner M has a main body case 10, a fan unit 20 that takes indoor air into the interior of the main body case 10, and an air cleaning filter 60 that cleans the air taken in by the fan unit 20. The person detecting device 55 detects the position of the person; and the automatic turning unit 40 changes the direction of the body box 10. The person detecting device 55 is provided in the main body case 10, and is rotated in the horizontal direction about the rotation axis Ja in the vertical direction. The automatic rotation unit 40 is rotated in the horizontal direction about the rotation axis Jb in the vertical direction to change the direction of the body case 10. Further, the automatic rotation unit 40 is driven in response to the detection result of the human detecting device 55. According to the above configuration, it is possible to obtain an air cleaner M that does not give a person an uncomfortable feeling due to a human detecting operation and can detect the direction of the correct person.

Further, the rotation axis Ja and the rotation axis Jb are oriented in the body case 10 toward the front The state in which the surface direction is stopped is arranged at approximately the center of the width of the main body case 10 in accordance with the positional relationship that overlaps when the main body is viewed from the front. Therefore, complex controls are not made and the direction of the right person can be detected.

Further, in the present invention, the rotation system includes not only a rotation operation of 360 degrees or more around the respective rotation axes but also a rotation operation of 360 degrees or less. For example, the main body case 10 facing the front or the human detecting device 55 is rotated by 45 degrees in the right direction about the rotation axis to change the direction.
