Description

Technical Field

[0001] The present disclosure relates to a humidifying device and a rotating frame assembly. Background Art

[0002] Patent document 1 discloses a humidifying device for humidifying air. The humidifying device includes a water storage portion and a humidifying mechanism having a rotating frame. The humidifying mechanism has a rotating frame and a water absorbing component held inside the rotating frame. The rotating frame is provided with a plurality of water supply components (buckets) for supplying water to the water absorbing component. When the rotating frame rotates, the water supply component moves in the water in the water storage portion at the lower side of the rotating frame. As a result, water enters the interior of the water supply component. When the water supply component moves toward the upper side of the rotating frame, the water inside the water supply component can be supplied to the water absorbing component through the injection port. By passing the air through the water absorbing component along the axial direction of the rotating frame, the water in the water absorbing component is imparted to the air. The air humidified as described above is supplied to the target space.

[0004] In Patent Document 1, the rotating frame is formed integrally with the water supply component by resin molding. This rotating frame is manufactured by injection molding in a mold. However, due to the structure of the water supply component, if the number of water supply components provided on the rotating frame is large, the molded part cannot be removed from the mold, so the number of water supply components that can be provided on the rotating frame by integral molding is limited.

[0005] The purpose of the present disclosure is to increase the number of water supply components provided on a rotating frame.

[0006] The first aspect is a humidifying device,

[0007] The humidifying device includes a humidifying mechanism 40, and the humidifying mechanism 40 has a rotating frame 45, a water absorbing component 70, a water storage part 33 and a first water supply component 80A. The rotating frame 45 is driven to rotate by a driving mechanism 41, the water absorbing component 70 is held inside the rotating frame 45 and allows air to pass through along the axial direction of the rotating frame 45, the water storage part 33 stores water for supplying to the water absorbing component 70, and the first water supply component 80A is used to draw up the water in the water storage part 33 and supply the drawn water to the water absorbing component 70.

[0008] The first water supply component 80A is formed integrally with the rotating frame 45.

[0009] The rotating frame 45 includes a mounting portion 100 to which a detachable second water supply member 80B is mounted.

[0010] In the first aspect, by attaching the second water supply member 80B to the first water supply member 80A integrally formed with the rotating frame 45 , the number of water supply members 80A and 80B can be increased.

[0014] The second injection port 92B injects the water drawn up by the second water supply member 80B into the water absorbing member 70.

[0015] The mounting portion 100 is formed such that the first injection port 92A and the second injection port 92B face the same direction with respect to the water absorbing member 70 .

[0016] In the second aspect, since the first injection port 92A and the second injection port 92B open in the same direction, water is supplied to the water absorbing member 70 from the same direction.

[0017] The third aspect is based on the first or second aspect.

[0018] The first water supply member 80A is formed at an upstream side of the water absorbing member 70 in the air flow direction along the axial direction.

[0019] In the third aspect, water can be poured into the water absorbing member 70 by utilizing the air flow flowing toward the water absorbing member 70. Therefore, scattering of water during the process of supplying water to the water absorbing member 70 can be suppressed.

[0023] The fifth aspect is based on any one of the first to fourth aspects,

[0024] The first water supply components 80A and the mounting portions 100 are alternately arranged along the outer periphery of the rotating frame 45 .

[0025] In the fifth aspect, compared with the case where the second water supply member 80B is not provided, the interval for supplying water to the water absorbing member 70 can be shortened by installing the second water supply member 80B between the first water supply members 80A adjacent in the circumferential direction of the rotating frame 45. In this way, the air passing through the water absorbing member 70 can be sufficiently humidified.

[0026] The sixth aspect is based on any one of the first to fifth aspects,

[0027] Six or more first water supply members 80A are formed on the rotating frame 45 .

[0028] In the sixth aspect, even in a state where the second water supply member 80B is not attached, the water absorbing member 70 can ensure a minimum water retention amount.

DETAILED DESCRIPTION

[0050] The following is a detailed description of the embodiments of the present disclosure with reference to the accompanying drawings. It should be noted that the present disclosure is not limited to the embodiments shown below, and various changes can be made without departing from the technical concept of the present disclosure. The drawings are used to conceptually illustrate the present disclosure, so for easy understanding, the size, ratio or number may be exaggerated or simplified as needed.

[0051] (1) Overall structure of the humidification device

[0052] Reference Figure 1 and Figure 2 The overall structure of the humidifier is described. It should be noted that in the following description, the terms related to "upper", "lower", "front", "back", "right" and "left" are generally used in the following manner. Figure 1 The direction indicated by the arrow is used as the reference.

[0053] The humidifying device of the present embodiment constitutes an air purifier 10 for purifying air. The air purifier 10 humidifies the air of the target space. And, the air purifier 10 purifies the air of the target space. The air purifier 10 has a housing 11 and a plurality of element components housed in an air passage P inside the housing 11. The plurality of element components include a pre-filter 21, a fan 22, a discharge unit 23, a UV irradiation unit 24, a HEPA filter 25, a deodorizing filter 26, and a humidifying unit 30 in order in the air flow direction.

[0054] (1-1) Shell

[0055] like Figure 1 As shown, the housing 11 is formed in a hollow box shape. The housing 11 is formed in a vertically long rectangular parallelepiped shape. The housing 11 has a top plate 11a, a bottom plate 11b, a front plate 11c, a rear plate 11d, a right side plate 11e, and a left side plate 11f.

[0056] The top plate 11a has a blow-out port 12. The blow-out port 12 is formed in a rectangular shape and is formed slightly behind the top plate 11a. Two air guide blades 13 are provided at the blow-out port 12. The air guide blades 13 are formed in a plate shape spanning the left and right ends of the blow-out port 12. The air guide blades 13 open and close the blow-out port 12 or adjust the wind direction of the blown air.

[0057] The top plate 11 a is provided with an operation panel 14 . The operation panel 14 is located at the front of the top plate 11 a . The user can input the operation mode of the air cleaner 10 and various settings by operating the operation panel 14 .

[0058] A first suction port 15 is formed at a lower end of the front plate 11c. The first suction port 15 extends horizontally across both left and right ends of the housing 11.

[0059] A second suction port 16 is formed on the right side plate 11e. The second suction port 16 is formed in a rectangular shape and is formed at the lower part of the right side plate 11e. An opening and closing cover 17 is provided at the upper part of the right side plate 11e. The opening and closing cover 17 is configured to open and close the access port 18 of the box 32 of the humidification unit 30. The opening and closing cover 17 is configured to tilt to the right side with its lower part as a fulcrum. A pull-out opening 19 is formed at the upper part of the opening and closing cover 17. The user pulls the pull-out opening 19 by hand and pulls the upper part of the opening and closing cover 17 to the right side (the front side). In this way, the upper part of the opening and closing cover 17 tilts to the right side, and the access port 18 opens. As a result, the user can take the water tank 32 out of the housing 11 through the access port 18.

[0060] The left side plate 11f is formed with a third suction port 20. The third suction port 20 is formed in a rectangular shape and is formed at a lower portion of the left side plate 11f.

[0106] Use below Figure 8 to Figure 10 The configuration of the first bucket 80A and the second bucket 80B will be described. It is assumed that the second bucket 80B is mounted on the mounting portion 100. It should be noted that the configuration common to the first bucket 80A and the second bucket 80B will be collectively referred to as "buckets 80A, 80B" for description. The configuration of the second bucket 80B that is different from the first bucket 80A will be described later.

[0107] The buckets 80A and 80B constitute a water container having an opening 80a. A water storage space S is formed inside the buckets 80A and 80B. The portion of the water storage space S other than the opening 80a is sealed by the buckets 80A and 80B. The opening 80a of the buckets 80A and 80B faces the rotation direction side of the rotating frame 45. In other words, the buckets 80A and 80B are formed into a bottomed cylindrical shape with one end on the rotation direction side opened and the other end on the opposite side of the rotation direction closed. The buckets 80A and 80B of this embodiment extend along the circumferential direction of the rotating frame 45.

[0108] The buckets 80A and 80B include a first plate portion 81, a second plate portion 82, a third plate portion 83, and a fourth plate portion 84. The first plate portion 81 is located radially outside the buckets 80A and 80B. The second plate portion 82 is located radially inside the buckets 80A and 80B. The third plate portion 83 is located axially on the side of the buckets 80A and 80B close to the water absorbing member 70. The fourth plate portion 84 is located axially on the side of the buckets 80A and 80B opposite to the water absorbing member 70.

[0109] In the first bucket 80A, the fourth plate portion 84 is formed by a portion of the base portion 52a of the first frame body 52. ​​The first bucket 80A is arranged upstream of the water absorbing member 70 in the air flow direction in the axial direction. In other words, the first bucket 80A is formed on the side of the base portion 52a facing the secondary space 31b.

[0110] The third plate portion 83 includes a first wall 83a, a second wall 83b, and a third wall 83c. The first wall 83a is formed on the radially outer side of the third plate portion 83, and the second wall 83b is formed on the radially inner side of the third plate portion 83. The first wall 83a is located axially farther from the fourth plate portion 84 than the third wall 83c. The third wall 83c is continuous with the radially outer end of the second wall 83b and the radially inner end of the first wall 83a.

[0111] When viewed in a cross section passing through the rotation axis X, the first plate portion 81 and the second plate portion 82 extend in the axial direction, and the fourth plate portion 84 extends in the radial direction. When viewed in a cross section passing through the rotation axis X, the first wall 83a and the second wall 83b extend in the radial direction. When viewed in a cross section passing through the rotation axis X, the third wall 83c is inclined so that the side closer to the water absorbing member 70 approaches the rotation axis X. Strictly speaking, the "cross section passing through the rotation axis X" refers to a cross section on a virtual plane passing through the rotation axis X and extending in the same direction as the rotation axis X.

[0112] The water storage space S is formed inside the first plate portion 81 , the second plate portion 82 , the third plate portion 83 , and the fourth plate portion 84 .

[0113] Fig.10 As shown, the second plate portion 82 is inclined so as to get closer to the rotation axis X as it moves in the rotation direction. Therefore, when the buckets 80A and 80B move to the upper side of the rotating frame 45, water in the water storage space S is easily introduced into the openings 80a of the buckets 80A and 80B.

[0114] (3-5) Configuration of injection port

[0115] The injection port 92 includes a first injection port 92A and a second injection port 92B. The first injection port 92A corresponds to the first bucket 80A. The second injection port 92B corresponds to the second bucket 80B. The first injection port 92A and the second injection port 92B have the same structure, and therefore, the first injection port 92A and the second injection port 92B are provided on the guide portion 90. The guide portion 90 is a portion that guides water flowing out of the opening 80a of the bucket 80A, 80B to the water absorbing member 70. The guide portion 90 is provided on the rotating frame 45 in a manner adjacent to the opening 80a of the bucket 80A, 80B on the rotation direction side. The guide portion 90 is located radially inward of the opening 80a of the bucket 80A, 80B. The guide portion 90 includes a recess 91 that is recessed radially inward.

[0116] The first injection port 92A and the second injection port 92B are formed inside the recessed portion 91. The first injection port 92A and the second injection port 92B are open toward the water absorbing member 70. Specifically, the first injection port 92A and the second injection port 92B are open toward the first ventilation surface 74 of the water absorbing member 70. The first ventilation surface 74 is a surface of the water absorbing member 70 located on the end side in the axial direction.

[0117] Since the first injection port 92A and the second injection port 92B are opened toward the first ventilation surface 74 of the water absorbing member 70, the water in the buckets 80A and 80B easily contacts the air passing through the water absorbing member 70. Therefore, the humidification capability of the water absorbing member 70 can be improved.

[0118] The recessed portion 91 includes a first side wall 93, a second side wall 94, and a bottom wall 95. The first side wall 93 is continuous with the inner edge of the opening 80a of the bucket 80A, 80B. The second wall 83b is opposite to the first side wall 93. When viewed from the axial direction, the first wall 83a and the second wall 83b extend in the radial direction. The bottom wall 95 extends from the radial inner end of the first side wall 93 to the radial inner end of the second side wall 94 in the circumferential direction.

[0119] like Fig. 9 and Fig.10 As shown, the guide portion 90 has a guide plate 99. The guide plate 99 is arranged on the side opposite to the opening 80a of the bucket 80A, 80B in the circumferential direction across the injection port 92. A plane 99a is formed on the guide plate 99, which is opposite to the opening 80a of the bucket 80A, 80B. The plane 99a of the guide plate 99 faces the opposite side of the rotation direction. The plane 99a of the guide plate 99 is located radially outward and on the positive side of the rotation direction than the second wall 83b. The water flowing out of the opening 80a of the bucket 80A, 80B collides with the plane 99a of the guide plate 99. The flow direction of the water after the collision changes from radial to axial, and is guided to the injection port 92.

[0120] (3-6) Structure of the holding unit

[0121] like Figure 7 and Fig.11 As shown, the second frame 60 is provided with a holding portion 66. The holding portion 66 is provided corresponding to each injection port 92. The holding portion 66 has a water blocking wall 66a, a fixing pin 66b protruding from the water blocking wall 66a toward the water absorbing member 70, and a fixing wall 66c surrounding the fixing pin 66b.

[0122] The water blocking wall 66a is located on the side opposite to the injection port 92 in the axial direction with the water absorbing member 70 sandwiched therebetween. The water blocking wall 66a is opposite to the injection port 92 with the water absorbing member 70 sandwiched therebetween. The water blocking wall 66a and the water absorbing member 70 overlap in the axial direction. The area of ​​the surface of the water blocking wall 66a located on the injection port 92 side is larger than the opening area of ​​the injection port 92. The water blocking wall 66a suppresses the water supplied from the injection port 92 to the water absorbing member 70 from passing through the water absorbing member 70. In this way, the amount of water retained inside the water absorbing member 70 can be increased.

[0123] The fixing pin 66b is located at the center of the surface of the water blocking wall 66a on the water absorbing member 70 side. The fixing pin 66b is formed into a trapezoidal cone shape whose outer diameter gradually decreases toward the water absorbing member 70 side. The fixing pin 66b is inserted into the insertion hole 79 of the water absorbing member 70. By fitting the fixing pin 66b into the insertion hole 79, the water absorbing member 70 is fixed to the second frame 60.

[0124] When viewed in a cross section perpendicular to the axial direction, the fixed wall 66c is formed in a U-shape with its radially outer side open. An annular flange portion 67 is formed on the surface of the second frame body 62 located on the water absorbing member 70 side and protruding in the axial direction. Both ends of the radially outer side of the fixed wall 66c are continuous with the inner peripheral surface of the flange portion 67. The fixed wall 66c is embedded in the second groove 78 of the water absorbing member 70. By fitting the fixed wall 66c and the water absorbing member 70, the water absorbing member 70 is fixed to the second frame 60.

[0125] As described above, the water blocking wall 66 a not only serves to suppress the passage of water through the water absorbing member 70 , but also serves as a member for fixing the water absorbing member 70 .

[0126] (3-7) Water supply port

[0127] like Figure 8 As shown, a plurality of first water supply ports 57 and a plurality of second water supply ports 55 are formed in the base 52a of the first frame body 52. ​​The first water supply ports 57 are openings for supplying water to the first bucket 80A, and the second water supply ports 55 are openings for supplying water to the second bucket 80B.

[0128] The first water supply port 57 is formed in a circular shape. The second water supply port 55 is formed in a rectangular shape. The first water supply port 57 is located on the front side of the opening 80a of the first bucket 80A in the rotation direction. The second water supply port 55 is located on the front side of the opening 80a of the second bucket 80B in the rotation direction.

[0129] When the first water supply port 57 is immersed in the water in the water tray 33, the water enters the first bucket 80A through the first water supply port 57. When the second water supply port 55 is immersed in the water in the water tray 33, the water enters the second bucket 80B through the second water supply port 55.

[0130] The second water supply port 55 serves to supply water to the second bucket 80B and to fix the second frame 60 to the base 52a.

[0131] (3-8) Detailed structure of the installation part

[0132] like Fig.12 and Fig.13As shown, the rotating frame 45 has a mounting portion 100 for mounting the detachable second bucket 80B. The mounting portion 100 is formed so that the first injection port 92A and the second injection port 92B face the same direction relative to the water absorbing member 70. Specifically, the mounting portion 100 is arranged on a flat portion of the base 52a of the first frame body 52 facing the secondary space 31b. In other words, the mounting portion 100 is formed on a surface of the base 52a of the first frame body 52 on one side of which the first bucket 80A is provided. In this way, the first bucket 80A and the second bucket 80B are provided on the portion of the base 52a facing the secondary space 31b.

[0133] The mounting portion 100 is configured so that one second bucket 80B can be mounted on each mounting portion 100. In the present embodiment, six mounting portions 100 are arranged at equal intervals along the circumferential direction of the first frame body 52. ​​The mounting portion 100 is arranged between two first buckets 80A adjacent in the circumferential direction of the first frame body 52. ​​Specifically, the mounting portion 100 is arranged in a region between the opening 80a of one of the two first buckets 80A adjacent in the circumferential direction in the base 52a and the guide plate 99 of the other.

[0134] The mounting portion 100 is configured such that, when the second bucket 80B is mounted on the mounting portion 100, the opening 80a of the second bucket 80B faces the rotation direction of the humidifying rotor 44. That is, when the second bucket 80B is mounted on the mounting portion 100, the opening 80a of the first bucket 80A and the opening 80a of the second bucket 80B face the same direction in the circumferential direction.

[0135] The mounting portion 100 has hook structures 54A and 54B that engage with the second bucket 80B. The hook structures 54A and 54B have a first mounting hole 54A and a second mounting hole 54B. The first mounting hole 54A and the second mounting hole 54B are arranged adjacent to each other in the circumferential direction of the base 52a. The engaging portions 110 and 120 provided on the second bucket 80B engage with the first mounting hole 54A and the second mounting hole 54B.

[0136] The first mounting hole 54A is formed into an approximately rectangular shape when viewed from the axial direction. Specifically, the first mounting hole 54A is divided by a pair of first radial sides M1 extending substantially in the radial direction and a pair of first circumferential sides N1 orthogonal to the first radial sides. The first mounting hole 54A is arranged behind the second mounting hole 54B in the rotation direction. The first mounting hole 54A is arranged near the first water supply port 57 of the first bucket 80A.

[0137] The second mounting hole 54B is formed into an approximately rectangular shape when viewed from the axial direction. Specifically, the second mounting hole 54B is divided by a pair of second radial sides M2 extending substantially in the radial direction and a pair of second circumferential sides N2 orthogonal to the second radial sides. The second mounting hole 54B is arranged near the guide plate 99 of the first bucket 80A. In other words, the second mounting hole 54B is formed near one end of the circumference of the mounting area of ​​the base 52a. A portion of the second mounting hole 54B is connected to the second water supply port 55. Specifically, the second mounting hole 54B is arranged on the opposite side of the rotation direction and on the radial inner side than the second water supply port 55.

[0138] (3-9) Detailed structure of the second bucket

[0139] Use below Fig.14 The second bucket 80B of this embodiment will be described. The fourth plate portion 84 of the second bucket 80B is in a state facing the mounting area. The structure different from the first bucket 80A will be described below.

[0140] The second bucket 80B has a first engaging portion 110 and a second engaging portion 120. The first engaging portion 110 and the second engaging portion 120 protrude axially from the fourth plate portion 84 toward the mounting area. The first engaging portion 110 engages with the first mounting hole 54A. The second engaging portion 120 engages with the second mounting hole 54B. When viewed from the first plate portion 81 side, the first engaging portion 110 and the second engaging portion 120 are formed into a substantially L-shape.

[0141] The first engaging portion 110 is provided at the end portion of the fourth plate portion 84 on the opposite side to the position of the opening 80a. The first engaging portion 110 is arranged at a position of the fourth plate portion 84 closer to the second plate portion 82 than the first plate portion 81. The first engaging portion 110 has a first mounting plate portion 111 and a first hook portion 112. The first mounting plate portion 111 stands up from the fourth plate portion 84. The plate surface of the first mounting plate portion 111 extends along the first radial side M1 of the first mounting hole 54A. The width of the first mounting plate portion 111 in the radial direction is substantially equal to the length of the first radial side M1 of the first mounting hole 54A. The first hook portion 112 is formed to extend from the top end of the first mounting plate portion 111 toward the opposite direction of the rotation direction (the side opposite to the position of the opening 80a), and then fold back toward the fourth plate portion 84. In other words, the top end of the first hook portion 112 faces the fourth plate portion 84 side.

[0142] The second engaging portion 120 is provided at the end portion of the fourth plate portion 84 on the side of the opening 80a. The second engaging portion 120 is arranged at a position of the fourth plate portion 84 that is closer to the second plate portion 82 than the first plate portion 81. The second engaging portion 120 has a second mounting plate portion 121 and a second hook portion 122. The second mounting plate portion 121 stands up from the fourth plate portion 84. The plate surface of the second mounting plate portion 121 extends along the second radial side M2 ​​of the second mounting hole 54B. The radial width of the second mounting plate portion 121 is substantially the same length as the second radial side M2 ​​of the second mounting hole 54B. The second hook portion 122 is formed to extend from the top end of the second mounting plate portion 121 toward the opposite direction of the rotation direction (the side opposite to the position of the opening 80a), and then fold back toward the fourth plate portion 84. In other words, the top end of the second hook portion 122 faces the fourth plate portion 84 side.

[0143] (4) Operation

[0144] Next, the operation of the air cleaner 10 will be described.

[0145] (4-1) Basic operation of air purifier

[0146] When the air purifier 10 is in operation, the fan 22, the discharge unit 23, the UV irradiation unit 24 and the humidification unit 30 are in operation. Figure 2 As shown, the air of the target space is sucked into the air passage P from the first suction port 15, the second suction port 16, and the third suction port 20. The air sucked from the second suction port 16 and the third suction port 20 passes through the prefilters 21. The prefilters 21 collect relatively large dust in the air.

[0147] The air passing through the pre-filter 21 passes around the discharge unit 23 and the UV irradiation unit 24. The active species generated by the discharge unit 23 oxidize and decompose the odorous components and harmful components in the air. The ultraviolet rays irradiated by the UV irradiation unit 24 sterilize the viruses and bacteria in the air.

[0148] Then, the air passes through the HEPA filter 25 and the deodorizing filter 26 in sequence, and then flows into the humidifying space 31. The air in the humidifying space 31 passes through the humidifying rotor 44 in the axial direction. At this time, the water in the water absorbing member 70 is added to the air. The air humidified in the humidifying rotor 44 is supplied to the target space from the blow-out port 12.

[0149] (4-2) Operation of the humidification unit

[0150] When the air cleaner 10 is operated, the humidifying unit 30 performs the following operations.

[0151] The driving mechanism 41 rotates the driving shaft 42. In this way, the humidifying rotor 44 rotates around the rotation axis X. When the rotating frame 45 rotates, the buckets 80A and 80B rotate around the rotation axis X. When the buckets 80A and 80B move to the lower side of the rotating frame 45 and enter the water in the water tray 33, the water enters the water storage space S of the buckets 80A and 80B. When the buckets 80A and 80B move upward and come out of the water in the water tray 33, the water storage space S of the buckets 80A and 80B draws up the water.

[0152] When the buckets 80A and 80B further move upward and reach a predetermined first angular position on the opposite side of the rotation direction from the upper end of the rotating frame 45 , the water in the water storage space S starts to flow down toward the opening 80 a .

[0153] When the rotating frame 45 further rotates, the water passing through the openings 80a of the buckets 80A and 80B is guided to the injection port 92 by the guide portion 90. Specifically, in the guide portion 90, the water passing through the openings 80a is sent to the injection port 92 along the bottom surface 97. The water passing through the injection port 92 is supplied from the first ventilation surface 74 of the water absorbing member 70 to the inside of the water absorbing member 70. The water in the water absorbing member 70 is supplied to the air flowing in the humidification space 31.

[0154] When the rotating frame 45 further rotates, the buckets 80A and 80B move to the lower side of the rotating frame 45 and re-enter the water in the water tray 33. The above-mentioned operation is continuously repeated.

[0155] (5) Method for manufacturing a rotating frame

[0156] Use below Figure 15 to Figure 17 The manufacturing method of the rotating frame 45 is described. In the present embodiment, it includes an installation process and an embedding process. In the installation process, the second bucket 80B is installed on the installation portion 100 of the first frame 50, and in the embedding process, the second frame 60 is embedded in the first frame 50 after the second bucket is installed. The above process is performed according to human operation. It should be noted that the water absorbing member 70 is provided on the first frame 50 in advance, but it can also be provided on the first frame 50 after the installation process.

[0157] In step S11, the user performs the installation process. In the installation process, the first engaging portion 110 of the second bucket 80B is hooked into the first mounting hole 54A, and the second engaging portion 120 is hooked into the second mounting hole 54B. Specifically, the first engaging portion 110 is pressed into the first mounting hole 54A, and the second engaging portion 120 is pressed into the second mounting hole 54B until the fourth plate portion 84 contacts the mounting portion 100. At this time, the first mounting plate portion 111 is clamped by the two first circumferential edges N1 of the first mounting hole 54A. The second mounting plate portion 121 is also clamped by the two second circumferential edges N2 of the second mounting hole 54B.

[0158] Then, the second bucket 80B is slid relative to the first frame 50 in the direction opposite to the rotation direction. In this way, the first mounting plate portion 111 abuts against one side of the first radial side M1 of the first mounting hole 54A that is on the side opposite to the rotation direction. The second mounting plate portion 121 also abuts against one side of the second radial side M2 ​​of the second mounting hole 54B that is on the side opposite to the rotation direction. In this state, the top end of the first hook portion 112 and the top end of the second hook portion 122 are respectively located on the primary space 31a side of the base portion 52a (see Fig.16 ). In other words, the first hook 112 hooks the first mounting hole 54A, and the second hook 122 hooks the second mounting hole 54B. As such, "engagement" means that the hooks 112 and 122 hook the mounting holes 54A and 54B.

[0159] In this way, the first engaging portion 110 is fixed to the first mounting hole 54A, and the second engaging portion 120 is fixed to the second mounting hole 54B, thereby preventing the second bucket 80B from falling off from the first frame body 52. ​​In particular, the first mounting plate portion 111 contacts the first radial side M1, and the second mounting plate portion 121 contacts the second radial side M2, thereby making it difficult for the second bucket 80B to shift in the circumferential direction.

[0160] Furthermore, in the process of the second bucket 80B moving and rising in the rotation direction after scooping up the water, the second bucket 80B is relatively heavy because of the water stored. However, since the first hook 112 hooks one side of the pair of first radial sides M1 on the opposite side of the rotation direction, the first hook 112 is difficult to be separated from the first mounting hole 54A due to the weight of the second bucket 80B containing water. Similarly, since the second hook 122 hooks one side of the pair of second radial sides M2 on the opposite side of the rotation direction, the second hook 122 is difficult to be separated from the second mounting hole 54B due to the weight of the second bucket 80B containing water. In this way, since both the first hook 112 and the second hook 122 are formed to extend in the opposite direction of the rotation direction, even if the second bucket 80B is heavy due to the water contained, it is possible to suppress the second bucket 80B from being separated from the first frame body 52 during the movement.

[0161] In step S12, the user performs the embedding process. When embedding and fixing, the second claws 65 of the second frame 60 are engaged with the second water supply port 55 of the first frame body 52. ​​Specifically, the second frame 60 is axially close to the first frame 50, and the six second claws 65 are respectively inserted into the second water supply port 55. Then, the second claws 65 are hooked on the second water supply port 55 (refer to Fig.17 ). In this way, the second frame 60 is difficult to deviate in the circumferential direction relative to the first frame 50, and the second frame 60 is difficult to detach from the first frame 50 in the axial direction. The "engagement" in step S12 means that the second claw 65 hooks the second water supply port 55.

[0162] (6) Features

[0163] (6-1) Feature 1

[0164] In the air cleaner 10 of the present embodiment, the first bucket 80A is formed integrally with the rotating frame 45. The rotating frame 45 has a mounting portion 100 to which the detachable second bucket 80B is mounted.

[0165] In this manner, by attaching the second bucket 80B to the attachment portion 100 in addition to the first bucket 80A formed integrally with the rotating frame 45 , the number of buckets 80A and 80B can be increased.

[0166] Furthermore, since the rotating frame 45 has the first bucket 80A in advance, the minimum amount of water supplied to the water absorbing member 70 per rotation of the humidifying rotor 44 can be ensured, and the amount of water supplied to the water absorbing member 70 can be increased by installing the second bucket 80B.

[0167] Furthermore, the amount of water supplied to the water absorbing member 70 per one rotation of the humidifying rotor 44 can be adjusted by adjusting the number of the second buckets 80B mounted on the mounting portion 100. In this way, the amount of humidification of the indoor air can be adjusted more finely.

[0168] In addition, when the buckets 80A and 80B are formed integrally with the rotating frame 45, there is a manufacturing problem that if the number of buckets 80A and 80B is large, it is impossible to remove the molded product from the mold. Therefore, in terms of the integral molded product, the number of buckets 80A and 80B that can be provided is limited. However, in this embodiment, the mounting portion 100 for mounting the second bucket 80B is provided on the rotating frame 45 formed integrally with the first bucket 80A. In this way, even if the rotating frame 45 is formed integrally with the buckets 80A and 80B, the second bucket 80B can be subsequently mounted, so that the number of buckets 80A and 80B can be increased.

[0169] (6-2) Feature 2

[0170] In the air cleaner 10 of the present embodiment, the attachment portion 100 is formed so that the first injection port 92A and the second injection port 92B face the same direction with respect to the water absorbing member 70 .

[0171] In this embodiment, since the mounting portion 100 is provided on the secondary space 31b side of the base 52a, the second bucket 80B is provided on the secondary space 31b side of the base 52a similarly to the first bucket 80A. In this way, the first injection port 92A and the second injection port 92B can be formed to face the same direction, and the first bucket 80A and the second bucket 80B can supply water to the water absorbing member 70 from the same direction.

[0172] If water flows out toward the secondary space 31 b , the water may be scattered along with the air flow. However, in the present embodiment, the first injection port 92A and the second injection port 92B allow the water to flow out toward the primary space 31 a , thereby suppressing the scattering.

[0173] (6-3) Feature 3

[0174] In the air cleaner 10 of the present embodiment, the first bucket 80A is formed at a position on the upstream side of the water absorbing member 70 in the air flow direction flowing in the axial direction.

[0175] In this way, water can be poured into the water absorbing member 70 by utilizing the air flow flowing toward the water absorbing member 70. Therefore, it is possible to suppress the water from scattering in the process of supplying water to the water absorbing member 70.

[0176] (6-4) Feature 4

[0177] In the air cleaner 10 of the present embodiment, the attachment portion 100 has hook structures 54A and 54B that engage with the second bucket 80B.

[0178] In this way, the second bucket 80B can be easily mounted on or removed from the mounting portion 100 by hooking the first mounting hole 54A with the first engaging portion 110 and hooking the second mounting hole 54B with the second engaging portion 120 .

[0179] (6-5) Feature 5

[0180] In the air cleaner 10 of the present embodiment, the first buckets 80A and the mounting portions 100 are alternately arranged along the outer periphery of the rotating frame 45 .

[0181] In this way, the second bucket 80B can be installed between the first buckets 80A adjacent to each other in the circumferential direction of the rotating frame 45. As a result, the water supply interval to the water absorbing member 70 can be shortened compared to the case where the second bucket 80B is not installed on the rotating frame 45. Therefore, the air passing through the water absorbing member 70 can be fully humidified.

[0182] (6-6) Feature 6

[0183] In the air cleaner 10 of the present embodiment, the rotating frame 45 has six first buckets 80A.

[0184] In this way, even in a state where the second bucket 80B is not attached, the water absorbing member 70 can ensure a minimum water retention amount.

[0185] (7) Other Implementation Methods

[0186] The above-mentioned embodiment may also adopt the following configuration.

[0187] In the above description, the case where six first buckets 80A are formed on the rotating frame 45 is described, but the present invention is not limited thereto. The number of first buckets 80A may be six or more, or five or less.

[0188] The above description describes the case where the first frame body 52 is composed of the first component C1 and the second component C2, but is not limited thereto. The first frame body 52 may also be configured without including the second component C2. That is, the rotating frame 45 includes the first bucket 80A, and the second bucket 80B may not be included in the components of the rotating frame 45. In other words, the air purifier 10 may also have a rotating frame group, which has a rotating frame 45 including the first bucket 80A and a second bucket 80B.

[0189] - Industrial Applicability -

[0190] In summary, the present disclosure is useful for a humidification device.
