(2-2) Maintenance of Humidifying Device 20 FIGS. 4 and 5 show an outline of a method for attaching and detaching the humidifying device 20 during maintenance. Fig.4 (a) is a perspective view which shows the external appearance of the air cleaner 10 before a maintenance. FIG. 5A shows an enlarged top section of the air cleaner 10 in the state shown in FIG. FIG. 4B shows a state in which the humidification tank 23 is taken out from the air cleaner 10. When taking out the humidification tank 23, hold the handle 23a of the humidification tank 23 and take it out. The state where the humidification tank 23 is further taken out from the state of FIG. 4B is the state shown in FIG. FIG. 4C shows a state next to the state shown in FIG. 5B, and in this state, the humidification tank 23 is completely removed from the air cleaner 10. As shown in FIGS. 4D and 5C, the humidifying rotor 25 can be pulled out together with the humidifying tray 22 after the humidifying tank 23 is taken out. At this time, the humidification motor 24 remains attached to the main body 21 as shown in FIG. When pulling out the humidifying tray 22, pull it out by holding the handle 22 a of the humidifying tray 22.

  As can be seen by comparing FIG. 5B and FIG. 5C, when the humidifying tray 22 is pulled out, the coupling for transmitting power from the humidifying motor 24 to the humidifying rotor 25 is cut. When the shaft part 31 shown in FIGS. 5C and 6 is disengaged from the bearing part 32, the coupling is cut.

  When the maintenance is finished and the air cleaner 10 is returned to the operable state, an operation reverse to the above-described procedure is performed. After the maintenance, first, the humidifying tray 22 is attached to the main body 21 of the humidifying device 20 in the main body casing 11 together with the humidifying rotor 25. When the humidifying tray 22 is attached to the main body 21, the two guide pins 22 b protruding in the front-rear direction (Y direction) of the humidifying tray 22 are fitted into the two guide grooves 21 b of the main body 21. However, in FIG. 6, a part of the main body 21 is shown to be broken, and only one guide groove 21 b is shown. When the humidifying tray 22 is attached to the main body 21, the coupling for transmitting power from the humidifying motor 24 to the humidifying rotor 25 is also restored (state shown in FIG. 5B). Next, the operation opposite to the above-described operation shown in FIGS. 4C, 4B, and 5B is performed to attach the humidification tank 23 to the humidification tray 22. When the attachment of the humidification tank 23 to the humidification tray 22 is completed, the upper right side plate 11e is flush with the right side surface of the main casing 11 as shown in FIGS. 4 (a) and 5 (a).

(2-3) Power transmission mechanism of the humidifying device 20 In order to transmit power from the humidifying motor 24 of the humidifying device 20 to the humidifying rotor 25 by an operation at the time of maintenance of the humidifying device 20 using FIG. 4 and FIG. Explained that the coupling of the slab was broken or recovered. Next, the power transmission mechanism of the humidifying device 20 will be described in more detail with reference to FIGS. 7 to 11 and suppression of vibration noise caused by the humidifying motor 24 will be described.

  FIG. 7 shows a cross section of the humidifier 20 in a state where it is removed from the air cleaner 10. FIG. 7 shows a state in which the shaft support portion 26 (see FIGS. 4C and 6) that supports the rotating shaft 25a of the humidifying rotor 25 is removed. FIG. 8 shows an enlarged cross section around the shaft part 31 and the bearing part 32.

  Between the humidification motor 24 and the humidification rotor 25, a power transmission mechanism 30 for transmitting the power of the humidification motor 24 to the humidification rotor 25 is formed. The power transmission mechanism 30 includes a shaft part 31 constituting the rotating shaft 25a of the humidifying rotor 25, a bearing part 32 that can be coupled to the shaft part 31, a gear 33 that transmits the rotation of the humidifying motor 24 to the bearing part 32, and a bearing part. A gear case 34 that rotatably supports the gear 32 and rotatably holds the gear 33, and an anti-vibration rubber 35 that is interposed between the gear case 34 and the main body 21 are provided.

  The shaft component 31 is fixed to the center of the disc-shaped humidification rotor 25 and rotates together with the humidification rotor 25. The shaft component 31 is supported by the shaft support portion 26 at two locations on both sides of the humidifying rotor 25, but the portion supported by the shaft support portion 26 is simply placed on the shaft support portion 26. It is. Therefore, if the humidification tray 22 is removed from the main body 21 and the humidification rotor 25 is held up by hand and pulled up, the humidification rotor 25 is easily detached from the shaft support portion 26 together with the shaft component 31.

  7 and 8 in which the humidifying tray 22 is attached to the main body 21, the convex part 31a of the shaft part 31 is fitted in the concave part 32a of the bearing part 32. By fitting the convex part 31a of the shaft part 31 into the concave part 32a of the bearing part 32, the shaft part 31 and the bearing part 32 are coupled so that power can be transmitted from the humidifying motor 24 to the humidifying rotor 25. . Since the bearing component 32 is connected to the humidification motor 24 via the gear 33, the rotational force of the humidification motor 24 is transmitted to the humidification rotor 25 via the gear 33, the bearing component 32, and the shaft component 31. Is done. In FIG. 8, a plane PL1 indicated by a broken line is a plane perpendicular to the rotation shaft 25a and passes through a portion where the shaft component 31 and the bearing component 32 are in contact with each other.

  The bearing part 32 is a drive shaft that is rotatably supported by the gear case 34. The gear case 34 houses not only the gear 33 but also the humidifying motor 24. The gear case 34 is attached to the main body 21 via an anti-vibration rubber 35.

(2-3-1) Main body 21
The main body 21 is made of plastic, has a front plate 21d and a rear plate 21e before and after the left side surface portion 21c, has an upper surface portion 21f on the upper side thereof, and has a bottom portion 21g on the lower side thereof. As described with reference to FIG. 3, since the air current blows into the humidifying device 20 from the bottom to the top, the air guide plate 21 h is provided on the left side surface portion 21 c in order to change the direction of the air flow to the direction of the humidifying rotor 25. Is formed inside. The airflow blown into the humidifier 20 from below passes through the humidifying rotor 25 from the space surrounded by the front plate 21d, the rear plate 21e, and the air guide plate 21h, and passes along the left side surface 23b of the humidifying tank 23. Guided upward.

  A gear case 34 is attached to the main body 21. That is, the main body 21 of the humidifier 20 is also a fixed frame of the gear case 34. In the main body 21, a storage portion 21a for attaching the gear case 34 is formed at substantially the center of the left side surface portion 21c. Specifically, the main body 21 supports the gear case 34 at the center of the plate-like portion 21ca that connects the first corner portion 21m and the second corner portion 21n. The first corner 21m is a connecting portion between the left side 21c and the front plate 21d, and the second corner 21n is a connecting portion between the left side 21c and the rear plate 21e.

  The main body 21 is formed with support bars 21p and 21q for attaching the first vibration isolation rubber 41 and the second vibration isolation rubber 42. The support bar 21p is disposed below the storage part 21a, and the support bar 21q is disposed above the storage part 21a. More specifically, support rods 21p and 21q are arranged on a vertical line 30b orthogonal to the rotation center 30a of the bearing component 32 that is a drive shaft. Accordingly, the first anti-vibration rubber 41 and the second anti-vibration rubber 42 are also disposed on the vertical line 30b. The support bar 21p protrudes in the X direction, and the support bar 21q protrudes in the Z direction. Corresponding to the protruding directions of these support bars 21p, 21q, the first vibration isolating rubber 41 is slid and inserted in the X direction, and the second vibration isolating rubber 42 is slid and inserted in the Z direction.

(2-3-2) Gear case 34
The gear case 34 is made of plastic, supports the bearing component 32 in a rotatable manner, houses a gear 33 engaged with the bearing component 32, and holds a humidifying motor 24 that drives the gear 33. ing. That is, the gear case 34 is a motor holder that is detachably attached to the shaft component 31 that is the rotating shaft of the humidifying rotor 25 via the bearing component 32.

  A humidifying motor 24 is fixed to the gear case 34 with screws 24a. A gear 33 is fixed to the rotating shaft of the humidifying motor 24, and the rotation of the humidifying motor 24 is directly transmitted to the gear 33. The rotation of the gear 33 is transmitted to the gear portion 32 d of the bearing part 32 meshing with the gear 33. The bearing component 32 is rotatably attached to a support shaft 34 a of the gear case 34.

  A first fitting portion 34p that is fitted to the first vibration isolating rubber 41 is formed at the lower end portion of the gear case 34, and the second vibration isolating rubber 42 is fitted to the upper end portion of the gear case 34. A second fitting portion 34q is formed. The first fitting portion 34p and the second fitting portion 34q have a C-shaped shape, and the diameters of the inner peripheral surfaces thereof are the fitted portions of the first vibration isolation rubber 41 and the second vibration isolation rubber 42. It is formed to be equal to the diameter of the outer peripheral surface.

  Since the humidification motor 24 is heavier than the plastic gear case 34, the upper and lower ends of the gear case 34 far from the humidification motor 24 are easily vibrated. Therefore, the vibration noise caused by the humidifying motor 24 can be effectively reduced by attenuating the vibration of the upper end portion and the lower end portion of the gear case 34.

(2-3-3) First anti-vibration rubber 41 and second anti-vibration rubber 42
As shown in FIG. 11, the first anti-vibration rubber 41 has flange portions 41 b at both ends of the fitted portion 41 a. The length of the fitted portion 41a, that is, the interval between the flange portions 41b is equal to the length of the first fitting portion 34p of the gear case 34. With this structure, when the first fitting portion 34p of the gear case 34 is fitted to the fitted portion 41a of the first vibration isolating rubber 41, the first fitting portion 34p with respect to the first vibration isolating rubber 41 in the X direction. The relative movement to is regulated by the flange 41b. As a result, the lower end portion of the gear case 34 is fixed by the first vibration isolating rubber 41 so as not to move in the X direction.

  Similarly, the second anti-vibration rubber 42 is formed with flange portions 42b at both ends of the fitted portion 42a. The length of the fitted portion 42a, that is, the interval between the flange portions 42b is equal to the length of the second fitting portion 34q of the gear case 34. With this structure, when the second fitting portion 34q of the gear case 34 is fitted to the fitted portion 42a of the second vibration isolating rubber 42, the second fitting portion 34q with respect to the second vibration isolating rubber 42 in the Z direction. The relative movement to is restricted by the flange 42b. As a result, the upper end portion of the gear case 34 is fixed by the second vibration isolating rubber 42 so as not to move in the Z direction.

  The first anti-vibration rubber 41 is stopped by providing a gap between the first anti-vibration rubber 41 and the flat washer so that the first anti-vibration rubber 41 does not come out of the support rod 21p by hitting the screw 21pa with the flat washer, for example. A clearance is provided between the flat washer so that it does not come out of the support bar 21q by hitting the attached screw 21qa.

  The first anti-vibration rubber 41 is fitted into the support bar 21p protruding in the X direction, and is fitted into a C-shaped first fitting portion 34p having a notch in the lower part. The first anti-vibration rubber 41 interposed between the support bar 21p and the first fitting portion 34p mainly attenuates the vibration in the Z direction and the vibration in the Y direction of the gear case 34.

  The second anti-vibration rubber 42 is fitted into the support rod 21q projecting in the Z direction, and fitted into a C-shaped second fitting portion 34q with a notch on the right side. The second anti-vibration rubber 42 interposed between the support rod 21q and the second fitting portion 34q mainly attenuates the vibration of the gear case 34 in the X direction and the vibration in the Y direction.

(3) Features (3-1)
As described above, the humidifier 20 is included in the main body 21 (an example of a fixed frame), the humidifying rotor 25, the gear case 34 (an example of a motor holder), and the first antivibration rubber 41 (an antivibration member group). An example of a first vibration isolation member) and a second vibration isolation rubber 42 (an example of a second vibration isolation member included in the vibration isolation member group) are provided. The gear case 34 is supported by the main body 21 and is detachably attached to a shaft component 31 (an example of a rotating shaft) of the humidifying rotor 25. The anti-vibration member group including the first anti-vibration rubber 41 and the second anti-vibration rubber 42 is provided between the support rods 21p and 21q of the main body 21 and the first fitting portion 34p and the second fitting portion 34q of the gear case 34.

  In the humidifier 20 configured as described above, the first vibration isolating rubber 41 attenuates vibrations in two directions of the Z direction and the Y direction, and the second vibration isolating rubber 42 is not attenuated by the first vibration isolating rubber 41. Attenuates vibration in the Y direction in addition to the direction. In this way, the first anti-vibration rubber 41 and the second anti-vibration rubber 42 are attenuated in the X, Y, and Z directions by causing the first anti-vibration rubber 41 and the second anti-vibration rubber 42 to attenuate in different directions. The vibration mode to be attenuated for 34 and the vibration mode to be attenuated for the gear case 34 by the second anti-vibration rubber 42 are different. As a result, the vibration mode at the position where the first anti-vibration rubber 41 and the second anti-vibration rubber 42 are provided becomes different, and resonance hardly occurs, and the humidification motor that drives the humidification rotor 25. The vibration sound caused by 24 is effectively suppressed.

  In particular, the first anti-vibration rubber 41 attenuates the vertical direction (Z direction) and the second anti-vibration rubber 42 attenuates one direction of the horizontal direction (X direction), so that the gear case 34 is supported from below. 1 It is possible to cause the vibration isolator 41 to attenuate the vibration. As a result, it is easy to realize the support of the gear case 34 for suppressing the vibration noise and the attenuation of the vibration of the gear case 34.

The first anti-vibration rubber 41 is arranged below the second anti-vibration rubber 42, and the first anti-vibration rubber 41 and the second anti-vibration rubber 42 are arranged apart from each other in the vertical direction. As described above, the first anti-vibration rubber 41 and the second anti-vibration rubber 42 are arranged apart from each other in the vertical direction, so that the position where the first anti-vibration rubber 41 is interposed and the second anti-vibration rubber 42 are interposed. The direction of rotational vibration that is likely to occur around a straight line that connects to the position to be moved can be greatly shifted with respect to the direction of the rotation axis of the humidifying rotor 25 and the direction orthogonal thereto. Since the humidifying rotor 25 is merely placed on the shaft support portion 26, the humidifying rotor 25 easily vibrates in the direction along the rotation axis (X direction) or in the vertical direction perpendicular to the rotation axis (Z direction). It has become. However, since the first anti-vibration rubber 41 and the second anti-vibration rubber 42 are arranged apart from each other in the vertical direction, vibration components in these directions can be reduced, and vibration caused by the humidification motor 24 is suppressed. It becomes easy to do.

  The gear case 34 holds the humidification motor 24, the first vibration isolation rubber 41 is disposed below the humidification motor 24, and the second vibration isolation rubber 42 is higher than the humidification motor 24. It is arranged above. That is, the first anti-vibration rubber 41 is disposed below the humidification motor 24 and the second anti-vibration rubber 42 is disposed above the humidification motor 24. Thereby, compared with the case where the 1st and 2nd anti-vibration rubber | gum 42 is arrange | positioned only above the comparatively heavy humidification motor 24, and the case where the 1st and 2nd anti-vibration rubber | gum 42 are arrange | positioned only below, The vibration direction of the relatively heavy humidification motor 24 can be easily regulated, and the vibration caused by the humidification motor 24 can be suppressed to suppress vibration noise.

  The gear case 34 further includes a bearing component 32 (an example of a rotating component) for transmitting the torque of the humidifying motor 24 to the rotating shaft of the humidifying rotor 25, and the first vibration isolating rubber 41 is a bearing component. 32 is arranged on a vertical line 30b orthogonal to the center of rotation 32 to support the lower end portion of the gear case 34, and a second anti-vibration rubber 42 is arranged on the vertical line 30b to support the upper end portion of the gear case 34 and the main body 21. It is intervened between. Therefore, the first vibration isolation rubber 41 and the second vibration isolation rubber 42 are arranged on the vertical line 30b, thereby effectively suppressing the bearing component 32 from vibrating in a plane including the rotation center 30a and the vertical line 30b. it can.

Since the first anti-vibration rubber 41 and the second anti-vibration rubber 42 are anti-vibration rubbers that can be attenuated in at least two directions, the first anti-vibration member and the second anti-vibration member can be formed relatively inexpensively. The vibration noise caused by the humidifying motor 24 can be suppressed relatively inexpensively.

(3-4)
The gear case 34 is provided with a gear 33 for transmitting torque to a shaft component 31 that is a rotating shaft of the humidifying rotor 25. Therefore, the freedom degree of the arrangement position of the humidification motor 24 becomes high, and the freedom degree of design of the humidification apparatus 20 can be raised. Further, the gear case 34 has the gear 33 and has a drawback that it is weak against vibration at the play portion. However, the first weak rubber 41 and the second vibration-proof rubber 42 can compensate for the weakness against vibration. As a result, it is possible to suppress vibration noise caused by the humidifying motor 24 while increasing the degree of freedom in designing the humidifying device 20.

(3-5)
The main body 21 supports the gear case 34 at the center of a plate-like portion 21ca that connects one first corner 21m and the other second corner 21n. Since the gear case 34 is supported at the center of the main body 21, the shaft component 31 of the humidifying rotor 25 can be easily arranged at the approximate center of the humidifying device 20, and as a result, the humidifying rotor 25 is arranged at the approximate center of the humidifying device 20. It becomes easy to do. As a result, it becomes easy to ensure the air volume for the humidifying rotor 25.

(4) Modification (4-1) Modification 1A
In the above-described embodiment, the case where the humidification rotor 25 is rotated by the humidification motor 24 has been described. However, the humidification rotor 25 may perform a reciprocating motion such as a seesaw in addition to rotation. The operation of the humidifying rotor 25 may be a rotation operation other than the rotation.

(4-2) Modification 1B
In the above embodiment, the case where the vibration isolating member group is composed of the two anti-vibration rubbers of the first anti-vibration rubber 41 and the second anti-vibration rubber 42 has been described, but the number of anti-vibration rubbers may be three or more. Good.

(4-3) Modification 1C
In the above-described embodiment, a case has been described in which the first vibration isolation rubber 41 mainly attenuates vibrations in the Z direction and the Y direction, and the second vibration isolation rubber 42 mainly attenuates vibrations in the X direction and the Y direction. However, the combination of vibration damping directions is not limited to this. Moreover, it may be expressed by coordinates other than XYZ coordinates, and it is only necessary to attenuate three-dimensional vibration with two or more vibration isolation members.
