In addition, the air outlet 19 communicates with the humidification chamber 13.

The blower fan 3 is a sirocco fan, for example, and blows air to the air purification filter 4. When the blower fan 3 is driven, an air flow from the left suction port 16 and the right suction port 17 to the air outlet 19 is generated. As shown in FIG. 1, this air flow flows in the order of the blower fan 3, the air purifying filter 4, and the humidifying unit 5 from below to above. The air purification filter 4 is disposed substantially horizontally between the blower fan 3 and the humidification unit 5.

Yes. These are arranged in the order of the upstream rotating member 31, the upstream humidifying filter 32, the downstream humidifying filter 33, and the downstream rotating member 34 from the upstream side to the downstream side of the air flow generated by the blower fan 3. The upstream side rotation member 31, the upstream side humidification filter 32, the downstream side humidification filter 33, and the downstream side rotation member 34 are respectively attached to the drive shaft 35 (shaft portion), and are integrated with the rotation of the drive shaft 35. Rotate to.

The upstream humidification filter 32 is a disk-shaped vaporization filter formed of, for example, a nonwoven fabric, and is attached to the upstream rotation member 31. A through hole 32A (hole) is formed at the center of the upstream humidifying filter 32, and the shaft main body 41 of the drive shaft 35 (shaft portion) passes therethrough. The upstream humidifying filter 32 rotates with the upstream rotating member 31, supplies moisture to the air flow passing through the upstream humidifying filter 32, and humidifies the air flow passing through the upstream humidifying filter 32.

The downstream humidification filter 33 has a configuration substantially similar to the upstream humidification filter 32 described above. The downstream humidifying filter 33 is a disk-shaped vaporizing filter formed of, for example, a nonwoven fabric, and is attached to the downstream rotating member 34. A through hole 33A (hole) is formed at the center of the downstream humidifying filter 33, and the shaft main body 41 of the drive shaft 35 (shaft portion) passes therethrough. The downstream humidifying filter 33 is disposed on the downstream side of the upstream humidifying filter 32 so that a gap is formed between the downstream humidifying filter 33 and the upstream humidifying filter 32. The downstream humidifying filter 33 rotates with the downstream rotating member 34, supplies moisture to the air flow passing through the downstream humidifying filter 33, and humidifies the air flow passing through the downstream humidifying filter 33. As shown in FIG. 3, the thickness T1 of the upstream humidifying filter 32 and the thickness T2 of the downstream humidifying filter 33 are substantially the same.

The size of the gap H between the upstream humidifying filter 32 and the downstream humidifying filter 33 is, for example, substantially the same as or larger than the thickness T1 of the upstream humidifying filter 32 or the thickness T2 of the downstream humidifying filter 33. . Further, for example, the thickness of the second bucket 71 (water splash member, second spacer) described later is approximately the same as the thickness of the first bucket 81 (water splash member, second spacer) described later. This gap H is provided in order to prevent the upstream humidifying filter 32 from moving and contacting the downstream humidifying filter 33 due to, for example, an air flow generated by the blower fan 3 to reduce the vaporization efficiency. As shown in FIG. 3, a first spacer 43 provided on the drive shaft 35 is disposed between the inner peripheral portion 32 I of the upstream humidifying filter 32 and the inner peripheral portion 33 I of the downstream humidifying filter 33. Therefore, a gap between the upstream humidifying filter 32 and the downstream humidifying filter 33 is maintained between the upstream humidifying filter 32 and the downstream humidifying filter 33. Further, a second bucket 71 (second spacer) described later and a first bucket 81 (second spacer) described later are provided between the outer peripheral portion 32O of the upstream humidifying filter 32 and the outer peripheral portion 33O of the downstream humidifying filter 33. Is arranged. Therefore, a gap between the upstream humidifying filter 32 and the downstream humidifying filter 33 is maintained at the outer peripheral portions of the upstream humidifying filter 32 and the downstream humidifying filter 33. The inner peripheral portion 32I of the upstream humidifying filter 32 and the inner peripheral portion 33I of the downstream humidifying filter 33 are, for example, from the inner edge of the upstream humidifying filter 32 and the downstream humidifying filter 33 to the center of the inner edge and the outer edge, respectively. Say range. Further, the outer peripheral portion 32O of the upstream humidifying filter 32 and the outer peripheral portion 33O of the downstream humidifying filter 33 are, for example, ranges from the outer edge of the upstream humidifying filter 32 and the downstream humidifying filter 33 to the center of the inner edge and the outer edge, respectively. To tell.

As shown in FIGS. 5 and 6, the upstream rotating member 31 (opposing member) is disposed on the upstream side of the upstream humidifying filter 32 and supports the upstream humidifying filter 32. The upstream rotating member 31 is disposed so as to face the upstream humidifying filter 32. The upstream rotating member 31 is arranged on the radially outer side of, for example, six frame portions 51 (frame portions of the upstream rotating member) extending radially outward from the central portion and the upstream humidifying filter 32. An annular outer wall portion 52 and a boss portion 53 that is arranged in the center portion and protrudes toward the downstream side. The six frame portions 51 support the upstream humidifying filter 32 from the upstream side of the upstream humidifying filter 32. The boss portion 53 is inserted into a through hole 32 A formed in the central portion of the upstream humidifying filter 32, and the shaft main body 41 of the drive shaft 35 is inserted inside the boss portion 53. The inner peripheral surface of the boss portion 53 and the outer peripheral surface of the shaft main body 41 of the drive shaft 35 are, for example, polygonal (for example, hexagonal) and have a corresponding size, and mesh with each other in the circumferential direction. Therefore, the upstream side rotation member 31 rotates integrally with the rotation of the drive shaft 35. As shown in FIG. 3, the inner peripheral portion 32 I of the upstream humidifying filter 32 is disposed between the six frame portions 51 and the first spacer 43 of the drive shaft 35, and the outer periphery of the upstream humidifying filter 32. The portion 32O is disposed between six frame portions 51 (frame portions of the upstream rotating member) and six first buckets 81 (first water hanger members) described later attached to the downstream rotating member 34. Yes.

The downstream rotating member 34 has substantially the same configuration as the upstream rotating member 31 described above. As shown in FIGS. 7 and 8, the downstream rotating member 34 is disposed downstream of the downstream humidifying filter 33 and supports the downstream humidifying filter 33. The downstream rotating member 34 is disposed so as to face the downstream humidifying filter 33. The downstream rotating member 34 is disposed on the radially outer side of, for example, six frame portions 61 (frame portions of the upstream rotating member) extending radially outward from the central portion and the downstream humidifying filter 33. An annular outer wall portion 62 and a boss portion 63 that is disposed at the center portion and protrudes toward the upstream side are provided. The six frame portions 61 support the downstream humidifying filter 33 from the downstream side of the downstream humidifying filter 33. The boss portion 63 is inserted into a through hole 33 A formed in the central portion of the downstream humidifying filter 33, and the shaft main body 41 of the drive shaft 35 is inserted inside the boss portion 63. The inner peripheral surface of the boss portion 63 and the outer peripheral surface of the shaft main body 41 of the drive shaft 35 are, for example, polygonal (for example, hexagonal) and have a corresponding size, and mesh with each other in the circumferential direction. Therefore, the downstream side rotation member 34 rotates integrally with the drive shaft 35 and the upstream side rotation member 31. As shown in FIG. 3, the inner peripheral portion 33 I of the downstream humidifying filter 33 is disposed between the six frame portions 61 and the first spacer 43 of the drive shaft 35, and the outer periphery of the downstream humidifying filter 33. The portion 33O is disposed between the six frame portions 61 and six second buckets 71 (water splash members), which will be described later, attached to the upstream rotation member 31. A plurality of claw portions 64 protruding toward the upstream side are formed on the outer wall portion 62 of the downstream side rotation member 34. The plurality of claw portions 64 engage with the recesses 54 formed in the outer wall portion 52 of the upstream side rotation member 31, so that the upstream side rotation member 31 and the downstream side rotation member 34 are inside the upstream side humidification filter 32. And the downstream humidifying filter 33 is integrated.

As shown in FIG. 3, the six first buckets 81 and the six second buckets 71 are disposed between the outer peripheral portion 32O of the upstream humidifying filter 32 and the outer peripheral portion 33O of the downstream humidifying filter 33, respectively. . Specifically, an inner portion 84 described later of the first bucket 81 and an inner portion 74 described later of the second bucket 71 are located between the outer peripheral portion 32O of the upstream humidifying filter 32 and the outer peripheral portion 33O of the downstream humidifying filter 33. Is arranged. The six first buckets 81 are for pumping water stored in the water tray 22 and watering it on the upstream humidifying filter 32, and are attached to the outer wall 62 of the downstream rotating member 34. Specifically, it arrange | positions so that it may protrude from the outer wall part 62 of the downstream rotation member 34 to an upstream. The six second buckets 71 are for pumping water stored in the water tray 22 and watering it on the downstream humidifying filter 33, and are attached to the outer wall portion 52 of the upstream rotating member 31. In detail, it arrange | positions so that it may protrude downstream from the outer wall part 52 of the upstream rotation member 31. FIG. The six first buckets 81 are arranged at positions (for example, equidistant) separated from each other in the circumferential direction of the downstream side rotation member 34, and the six second buckets 71 are separated from each other in the circumferential direction of the upstream side rotation member 31. They are arranged at positions (for example, at equal intervals).

As shown in FIGS. 7 and 8, the first bucket 81 (water hanger member, second spacer) is formed in front of the bucket portion 82 in which water is stored and the downstream side rotary member 34 in the rotation direction, and the bucket portion 82. A first water outlet 83 that communicates with the outer wall 62 and a first water outlet that is provided in an inner portion 84 that protrudes radially inward from the outer wall 62 of the downstream rotating member 34 and that opens toward the upstream humidifying filter 32. 85. The first water drawing port 83 of the first bucket 81 is disposed inside the water tray 22 in a state where it is located near the lower end of the downstream side rotation member 34. Therefore, water is pumped from the first water pumping opening 83 of the first bucket 81 to the bucket portion 82. Then, when the first bucket 81 moves with the rotation of the downstream rotation member 34 and the first water discharge port 85 moves to the vicinity of the upper end of the downstream rotation member 34, water is discharged from the first water discharge port 85. Then, the upstream humidification filter 32 is watered. As shown in FIGS. 3 and 7, the inner portion 84 has a protruding portion 86 that protrudes so that the first water discharge port 85 protrudes upstream from the upstream end of the bucket portion 82. The first water discharge port 85 is pressed against the downstream humidifying filter 33. The inner portion 84 has a rib 87 protruding downstream. In the air cleaner 1, the first water discharge port 85 faces the upstream humidification filter 32, but the first water discharge port 85 is not necessarily open to the upstream humidification filter 32. If the water discharge port 85 does not indicate that the upstream humidification filter 32 is opposed to the water and the water discharged from the first water discharge port 85 is put on the upstream humidification filter 32, the first The water discharge port 85 may not face the upstream humidifying filter 32.

The second bucket 71 (water splash member, second spacer) has substantially the same configuration as the first bucket 81. As shown in FIGS. 5 and 6, the second bucket 71 includes a bucket portion 72 in which water is stored and a second water pump that is formed in front of the upstream rotating member 31 in the rotation direction and communicates with the bucket portion 72. It has a port 73 and a second water discharge port 75 that is provided in an inner portion 74 that protrudes radially inward from the outer wall portion 52 of the upstream rotating member 31 and opens toward the downstream humidifying filter 33. . The second water drawing port 73 of the second bucket 71 is disposed inside the water tray 22 in a state of being located near the lower end of the upstream side rotation member 31. Accordingly, water is pumped from the second water pumping port 73 of the second bucket 71 to the bucket portion 72. When the second bucket 71 moves with the rotation of the upstream rotation member 31 and the second water discharge port 75 moves near the upper end of the upstream rotation member 31, water is discharged from the second water discharge port 75. Then, the water is applied to the downstream humidifying filter 33. As shown in FIGS. 3 and 5, the inner portion 74 has a protruding portion 76 that protrudes so that the second water discharge port 75 protrudes downstream from the downstream end portion of the bucket portion 72. The second water discharge port 75 is pressed against the upstream humidifying filter 32. The inner portion 74 has a rib 77 protruding upstream. As shown in FIG. 3, the thickness T4 of the bucket portion 82 of the first bucket 81 and the thickness T3 of the bucket portion 72 of the second bucket 71 are substantially the same. 6 and 8, the circumferential length of the bucket portion 82 of the first bucket 81 and the circumferential length of the bucket portion 72 of the second bucket 71 are also substantially the same. Therefore, the amount of water stored in the bucket portion 82 of the first bucket 81 and the amount of water stored in the bucket portion 82 of the second bucket 71 are substantially the same. In the air purifier 1, the second water discharge port 75 faces the downstream humidifying filter 33, but the second water discharge port 75 is not necessarily open to the downstream humidifying filter 33. It does not indicate that the water discharge port 75 is opposed to the downstream humidifying filter 33, and if the water discharged from the second water discharge port 75 is poured onto the downstream humidifying filter 33, the second The water discharge port 75 may not face the downstream humidifying filter 33.

Here, the positions (A)-(F) shown in FIG. 6 correspond to the positions (A)-(F) shown in FIG. Accordingly, all of the six first buckets 81 and the six second buckets 71 are arranged so as to be shifted in the circumferential direction of the upstream rotating member 31 and the downstream rotating member 34. Here, the fact that the first bucket 81 and the second bucket 71 are arranged so as to be shifted in the circumferential direction means that the first bucket 81 and the second bucket 71 do not overlap when viewed from the axial direction of the drive shaft 35. To do.

At least a part of the first bucket 81 and the second bucket 71 is disposed on the same plane parallel to the upstream side rotation member 31 and the downstream side rotation member 34 (on the same plane orthogonal to the air flow direction). . In other words, as shown in FIG. 9, when viewed from the radially outer side (side surface) of the humidifying unit 21, at least a part of the first bucket 81 and the second bucket 71 is in a direction orthogonal to the air flow direction ( It overlaps in the direction orthogonal to the axial direction of the drive shaft 35 (the vertical direction in FIG. 9).

Further, as shown in FIGS. 6 and 8, all of the six first water discharge ports 85 and the six second water discharge ports 75 are shifted in the circumferential direction of the upstream side rotation member 31 and the downstream side rotation member 34. Be placed. Here, the first water discharge port 85 and the second water discharge port 75 are arranged so as to be shifted in the circumferential direction when viewed from the axial direction of the drive shaft 35. This means that the outlets 75 do not overlap.

As shown in FIGS. 5 and 6, the upstream rotating member 31 protrudes toward the downstream side, enters the outer peripheral portion 32 O of the upstream humidifying filter 32, and fixes the upstream humidifying filter 32 to the upstream rotating member 31. There are six first protrusions 91 (protrusions). Specifically, the six first projecting portions 91 pass through holes 32H (see FIG. 4) formed in the outer peripheral portion 32O of the upstream humidifying filter 32. The first protruding portion 91 protrudes downstream from each of the six frame portions 51.

All of the six first protrusions 91 and the second bucket 71 attached to the upstream rotating member 31 are arranged so as to be shifted in the circumferential direction of the upstream rotating member 31 as shown in FIG. For example, when the first protrusion 91 is disposed at the same position as the second bucket 71 in the circumferential direction of the upstream rotating member 31, when the upstream humidifying filter 32 is attached to the upstream rotating member 31, the upstream side The operation of placing the humidifying filter 32 between the six frame portions 51 of the upstream rotating member 31 and the second bucket 71 (the operation of sandwiching) and the operation of causing the first protruding portion 91 to enter the upstream humidifying filter 32 are substantially omitted. Since it is necessary to carry out simultaneously, the operation | work which attaches the upstream humidification filter 32 to the upstream rotation member 31 becomes complicated. However, since all of the first protrusion 91 and the second bucket 71 are shifted in the circumferential direction of the upstream rotating member 31 in the upstream rotating member 31 of the present embodiment, the upstream humidifying filter 32 is disposed upstream. Since the first projecting portion 91 may enter the upstream humidifying filter 32 after being arranged (after being sandwiched) between the six frame portions 51 of the side rotating member 31 and the second bucket 71, or Conversely, after the first protruding portion 91 has entered the upstream humidifying filter 32, the upstream humidifying filter 32 can be disposed between the six frame portions 51 of the upstream rotating member 31 and the second bucket 71. Therefore, it is easy to attach the upstream humidifying filter 32 to the upstream rotating member 31.

As shown in FIGS. 7 and 8, the downstream rotating member 34 protrudes toward the upstream side, enters the outer peripheral portion 33 O of the downstream humidifying filter 33, and moves the downstream humidifying filter 33 to the downstream rotating member 34. There are six second protrusions 93 to be fixed to the head. Specifically, the six second protruding portions 93 pass through holes 33H (see FIG. 4) formed in the outer peripheral portion 33O of the downstream humidifying filter 33. The second protruding portion 93 protrudes downstream from each of the six frame portions 61. The second protrusion 93 has substantially the same configuration as the first protrusion 91 described above.

All of these six second projecting portions 93 and the first bucket 81 attached to the downstream side rotation member 34 are shifted in the circumferential direction of the downstream side rotation member 34 as shown in FIG. For example, when the second protrusion 93 is disposed at the same position as the first bucket 81 in the circumferential direction of the downstream side rotation member 34, the downstream side humidifier filter 33 is attached to the downstream side rotation member 34 at the downstream side. The operation of placing the humidifying filter 33 between the six frame portions 61 of the downstream side rotation member 34 and the first bucket 81 (the operation of sandwiching) and the operation of causing the second protruding portion 93 to enter the downstream side humidifying filter 33 are substantially omitted. Since it is necessary to carry out simultaneously, the operation | work which attaches the downstream humidification filter 33 to the downstream rotation member 34 becomes complicated. However, since the downstream side rotation member 34 of the present embodiment is arranged such that all of the second protrusion 93 and the first bucket 81 are shifted in the circumferential direction of the downstream side rotation member 34, the downstream side humidifying filter 33 is moved downstream. Since the second projecting portion 93 may be made to enter the upstream humidifying filter 32 after being arranged (after being sandwiched) between the six frame portions 61 of the side rotating member 34 and the first bucket 81, or Conversely, after the second projecting portion 93 has entered the downstream humidifying filter 33, the downstream humidifying filter 33 can be disposed between the six frame portions 61 of the downstream rotating member 34 and the first bucket 81. Since it is sufficient if it is sandwiched, it is easy to attach the downstream humidifying filter 33 to the downstream rotating member 34.

As shown in FIGS. 5 and 6, the upstream rotating member 31 is arranged in the vicinity of the upstream side of the upstream humidifying filter 32 and is attached to the downstream rotating member 34 when viewed from the upstream side. There are six first shielding plates 92 provided so as to overlap substantially the entire area of the six first water discharge ports 85 of the bucket 81. The first shielding plate 92 prevents the discharge of water from the first water discharge port 85 of the first bucket 81 due to the wind pressure of the air flow generated by the blower fan 3. The first shielding plate 92 overlaps substantially the entire area of the first water discharge port 85 as viewed from the upstream side, but at least a part of the first shielding plate 92 only needs to overlap.

As shown in FIGS. 7 and 8, the downstream rotating member 34 is disposed in the vicinity of the downstream side of the downstream humidifying filter 33 and is attached to the upstream rotating member 31 when viewed from the downstream side. There are six second shielding plates 94 provided so as to overlap substantially the entire area of the six second water discharge ports 75 of the bucket 71. By the second shielding plate 94, water discharged from the second water discharge port 75 of the second bucket 71 and penetrating the downstream humidifying filter 33 collides with the second shielding plate 94. Therefore, the water discharged from the second water discharge port 75 of the second bucket 71 can be prevented from scattering. Note that the second shielding plate 94 overlaps substantially the entire area of the second water discharge port 75 as viewed from the downstream side, but it is sufficient that at least a part thereof overlaps.

In the air cleaner 1 of the present embodiment, the first bucket 81 that hangs the upstream humidifying filter 32 is not the upstream rotating member 31 to which the upstream humidifying filter 32 is attached, but the downstream humidifying filter 33 is attached. Attached to the downstream rotating member 34. Further, the second bucket 71 that hangs on the downstream humidifying filter 33 is attached to the upstream rotating member 31 to which the upstream humidifying filter 32 is attached, not to the downstream rotating member 34 to which the downstream humidifying filter 33 is attached. . Therefore, there are the following two features.

(Feature 1)
For example, when the opposing member on which the upstream humidifying filter 32 is supported is the same as the opposing member to which the first bucket for watering the upstream humidifying filter 32 is attached, that is, the first bucket 81 becomes the upstream rotating member 31. In order to configure the first water discharge port 85 (protruding portion 86) to be pressed against the upstream humidifying filter 32 when it is attached, six upstream rotating members 31 that support the upstream humidifying filter 32 are provided. The space between the frame portion 51 and the first water discharge port (protruding portion) of the first bucket attached to the upstream rotating member 31 is narrowed, and the upstream humidifying filter 32 is disposed in the narrow space. There is a need. Therefore, in order to configure the first water discharge port 85 (protruding portion 86) to be pressed against the upstream humidifying filter 32, it is complicated to attach the upstream humidifying filter 32 to the upstream rotating member 31. Similarly, when the opposing member on which the downstream humidifying filter 33 is supported is the same as the opposing member to which the second bucket 71 that is watered on the downstream humidifying filter 33 is attached, the downstream humidifying filter 33. The attachment to the downstream rotating member 34 becomes complicated.

However, in the air cleaner 1 of the present embodiment, the facing member that supports the upstream humidifying filter 32 is different from the facing member to which the first bucket 81 that is watered on the upstream humidifying filter 32 is attached, that is, upstream. The side humidification filter 32 is attached to the upstream side rotation member 31 and the first bucket 81 is attached to the downstream side rotation member 34. Therefore, as shown in FIG. 10A, after the upstream humidifying filter 32 is attached to the upstream rotating member 31, as shown in FIG. 10B, the upstream rotating member 31 and the downstream rotating member 34. And the first water discharge port 85 (projecting portion 86) of the first bucket 81 is pressed against the upstream humidifying filter 32, so that the upstream rotating member of the upstream humidifying filter 32 is engaged. The first water discharge port 85 (protruding portion 86) can be configured to be pressed against the upstream humidifying filter 32 without being complicated to attach to 31. Similarly, the second water discharge port 75 (protruding portion 76) is configured to be pressed against the downstream humidifying filter 33 without making the downstream humidifying filter 33 attached to the downstream rotating member 34 complicated. It becomes possible.

(Feature 2)
For example, when the opposing member on which the upstream humidifying filter 32 is supported is the same as the opposing member to which the first bucket that hangs on the upstream humidifying filter 32 is attached, that is, the first bucket 81 is the upstream rotating member. When attached to 31, the first shielding plate 92 and the first water discharge port of the first bucket face each other when the upstream rotating member 31 alone is viewed. For this reason, it is impossible to remove the mold for forming the first water discharge port to the upstream side in the axial direction, and it becomes difficult to form the upstream rotating member 31. Similarly, in the downstream rotating member 34, the second shielding plate 94 and the second water discharge port of the second bucket are opposed to each other, so that a mold for forming the second water discharge port is provided. It becomes impossible to pull it downstream in the axial direction, and it becomes difficult to form the downstream rotating member 34.

However, in the air cleaner 1 of the present embodiment, the opposing member that supports the upstream humidifying filter 32 is different from the opposing member to which the first bucket 81 that is watered on the upstream humidifying filter 32 is attached. As shown, the first shielding plate 92 of the upstream side rotation member 31 and the first water discharge port 85 of the first bucket 81 do not face each other. Therefore, it is easy to mold the upstream rotating member 31 with a mold. Similarly, as shown in FIG. 8, the second shielding plate 94 of the downstream rotating member 34 and the second water discharge port 75 of the second bucket 71 do not face each other. Therefore, it is easy to mold the downstream rotating member 34 with a mold.

<Water tray>
As shown in FIG. 2, the water tray 22 (water storage unit) is disposed below the humidification unit 21 and stores water supplied to the upstream humidification filter 32 and the downstream humidification filter 33 of the humidification unit 21. . The water tray 22 is provided with a float (not shown) for determining whether or not the amount of water in the water tray 22 is equal to or greater than a predetermined amount. Moreover, this water tray 22 has two

support parts

22a and 22b (refer FIG. 3) which support the drive shaft 35 of the humidification part 21 from the downward direction.

<Water storage tank>
The water storage tank 23 is disposed above the water tray 22 and downstream of the humidifying unit 21. A water injection port (not shown) is provided in the lower part of the water storage tank 23, and the water in the water storage tank 23 flows out into the water tray 22 through the water injection port due to a decrease in the water level in the water tray 22.

<Drive mechanism>
The drive mechanism 24 drives the drive shaft 35 of the humidifying unit 21 to rotate. As shown in FIG. 3, the drive mechanism 24 includes an attachment portion 24a to which the end portion 42 of the shaft main body 41 of the drive shaft 35 is attached, and a motor 24b. Have.

As shown in FIG. 11, the drive shaft 35 (shaft portion) includes a shaft main body 41 and the above-described first spacer 43 formed integrally with the shaft main body 41. The end portion 42 of the shaft main body 41 of the drive shaft 35 is configured to mesh with the mounting portion 24 a of the drive mechanism 24 in the circumferential direction of the drive shaft 35 and to be removable in the axial direction of the drive shaft 35. Specifically, the outer peripheral surface of the end portion 42 of the drive shaft 35 and the inner peripheral surface of the mounting portion 24a of the drive mechanism 24 are formed in, for example, a polygon (for example, a hexagon) and a size corresponding to each other, so And can be removed in the axial direction of the drive shaft 35. In addition, this humidification unit 5 (the humidification part 21, the water tray 22, and the water storage tank 23) is removed from the door of the right side surface 15 horizontally as shown in FIG.

<Characteristics of the air purifier according to this embodiment>

Since the second spacer) is arranged, it is possible to prevent the upstream humidifying filter 32 and the downstream humidifying filter 33 from coming into contact with each other at the outer peripheral portions of the upstream humidifying filter 32 and the downstream humidifying filter 33. Therefore, it is easier to prevent the upstream humidifying filter 32 and the downstream humidifying filter 33 from contacting each other.

Moreover, in the air cleaner 1 of this embodiment, since the 1st bucket 81 (water hanger member) and the 2nd bucket 71 (water hanger member) serve as a spacer, it is not necessary to newly provide a member for a spacer. Therefore, it is possible to prevent the upstream humidifying filter 32 and the downstream humidifying filter 33 from contacting each other at the outer peripheral portions of the upstream humidifying filter 32 and the downstream humidifying filter 33 without increasing the member cost.

Moreover, in the air cleaner 1 of this embodiment, the 1st protrusion part for approaching the outer peripheral part 32O of the upstream humidification filter 32, and fixing the upstream humidification filter 32 to the upstream rotation member 31 (opposing member). Since it has 91 (protrusion part), it is easier to prevent the upstream humidification filter 32 and the downstream humidification filter 33 from coming into contact with each other at the outer peripheral portions of the upstream humidification filter 32 and the downstream humidification filter 33.

Moreover, in the air cleaner 1 of this embodiment, since the drive shaft 35 (shaft part) can be easily removed from the drive mechanism 24, the maintainability of the air cleaner 1 (humidifier) is improved.
