Description

[Technical field]

[0001] The present disclosure relates to a humidification device. [Background technology]

[0002] Patent Document 1 discloses a humidifying device that humidifies air. The humidifying device includes a water storage section and a humidifying mechanism having a rotating frame. The humidifying mechanism includes a rotating frame and a water-absorbing member held inside the rotating frame. The rotating frame is provided with a plurality of water supply members (buckets) for supplying water to the water-absorbing member. When the rotating frame rotates, the water supply member moves through the water in the water storage section below the rotating frame. As a result, water enters the water supply member. When this water supply member moves to the upper side of the rotating frame, the water inside the water supply member is supplied to the water-absorbing member through the spout. When air passes through the water-absorbing member in the axial direction of the rotating frame, the water from the water-absorbing member is applied to the air. The air humidified in this manner is supplied to a target space. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-20627 A Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, the rotating frame is integrally formed with the water supply member by resin molding. Such a rotating frame is manufactured by injection molding in a mold. However, due to the structure of the water supply member, if the number of water supply members provided on the rotating frame is increased, the molded product cannot be removed from the mold, so there is a limit to the number of water supply members that can be provided on the rotating frame by integral molding.

[0005] An object of the present disclosure is to increase the number of water supply members provided on a rotating frame. [Means for solving the problem]

[0006] The first aspect is a humidification mechanism (40) including a rotary frame (45) rotated by a drive mechanism (41), a water-absorbing member (70) held inside the rotary frame (45) and through which air passes in the axial direction of the rotary frame (45), a water storage section (33) that stores water to be supplied to the water-absorbing member (70), and a first water supply member (80A) that pumps up water in the water storage section (33) and supplies the pumped water to the water-absorbing member, The first water supply member (80A) is formed integrally with the rotary frame (45), The rotary frame (45) is a humidifier having an attachment portion (100) to which a detachable second water supply member (80B) is attached.

[0007] In the first embodiment, by attaching a second water supply member (80B) in addition to the first water supply member (80A) integrally formed with the rotary frame (45), the number of water supply members (80A, 80B) can be increased.

[0008] The second aspect is the first aspect, The rotating frame (45) is a first spout (92A) for pouring water pumped up by the first water supply member (80A) into the water absorption member (70); a second spout (92B) for pouring the water pumped up by the second water supply member (80B) into the water absorbing member (70); Equipped with The attachment portion (100) is formed so that the first spout (92A) and the second spout (92B) face in the same direction relative to the water absorbent member (70).

[0009] In the second embodiment, the first spout (92A) and the second spout (92B) open in the same direction, and therefore water is supplied to the water absorbent member (70) from the same direction.

[0010] The third aspect is the first or second aspect, The first water supply member (80A) is located upstream of the water absorbing member (70) in the air flow in the axial direction.

[0011] In the third aspect, water can be poured into the water absorption member (70) by utilizing the air flow toward the water absorption member (70). This makes it possible to prevent water from splashing while being supplied to the water absorption member (70).

[0012] A fourth aspect is any one of the first to third aspects, The attachment portion (100) has hook structures (54A, 54B) that engage with the second water supply member (80B).

[0013] In the fourth embodiment, the second water supply member (80B) can be easily attached or detached by the hook structures (54A, 54B).

[0014] A fifth aspect is any one of the first to fourth aspects, The first water supply members (80A) and the mounting portions (100) are arranged alternately along the outer periphery of the rotary frame (45).

[0015] In the fifth aspect, by attaching the second water supply member (80B) between the first water supply members (80A) adjacent to each other in the circumferential direction of the rotating frame (45), the interval at which water is supplied to the water absorption member (70) can be made shorter than in the case where the second water supply member (80B) is not provided. This allows the air passing through the water absorption member (70) to be sufficiently humidified.

[0016] A sixth aspect is any one of the first to fifth aspects, Six or more of the first water supply members (80A) are formed on the rotary frame (45).

[0017] In the sixth aspect, even when the second water supply member (80B) is not attached, the water absorption member (70) can ensure a minimum amount of water retention.

[0018] A seventh aspect is a method for manufacturing the rotary frame (45), comprising the step of attaching the second water supply member (80B) to the attachment portion (100) of any one of the first to sixth aspects.

[0019] The eighth aspect is a rotating frame set including the rotating frame (45) of any one of the first to sixth aspects and the second water supply member (80B). [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below, and various modifications are possible within the scope of the technical idea of ​​the present disclosure. Since each drawing is intended to conceptually explain the present disclosure, dimensions, ratios, or numbers may be exaggerated or simplified as necessary for ease of understanding.

[0022] (1) Overall configuration of the humidifier The overall configuration of the humidifier will be described with reference to Figures 1 and 2. In the following description, the terms "upper," "lower," "front," "rear," "right," and "left" are, in principle, based on the directions indicated by the arrows in Figure 1.

[0023] The humidifying device of this embodiment constitutes an air purifier (10) that purifies air. The air purifier (10) humidifies the air in a target space. In addition, the air purifier (10) purifies the air in the target space. The air purifier (10) has a casing (11) and a plurality of components housed in an air passage (P) inside the casing (11). The plurality of components include, in order along the air flow, a prefilter (21), a fan (22), a discharge unit (23), a UV irradiation unit (24), a HEPA filter (25), a deodorizing filter (26), and a humidification unit (30).

[0024] (1-1) Casing As shown in Fig. 1, the casing (11) is formed in a hollow box shape. The casing (11) is formed in a vertically long rectangular parallelepiped shape. The casing (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).

[0025] An air outlet (12) is formed in the top plate (11a). The air outlet (12) is formed in a rectangular shape, and is formed slightly toward the rear of the top plate (11a). Two flaps (13) are provided in the air outlet (12). The flaps (13) are formed in a plate shape spanning both the left and right ends of the air outlet (12). The flaps (13) open and close the air outlet (12) and adjust the direction of the air blown out.

[0026] An operation panel (14) is provided on the top plate (11a). The operation panel (14) is located toward the front of the top plate (11a). A user can operate the operation panel (14) to input an operation mode and various settings of the air purifier (10).

[0027] A first suction port (15) is formed at the lower end of the front plate (11c) and extends horizontally from the left to the right ends of the casing (11).

[0028] A second suction port (16) is formed in the right side plate (11e). The second suction port (16) is formed in a rectangular shape and is formed in the lower part of the right side plate (11e). An openable lid (17) is provided in the upper part of the right side plate (11e). The openable lid (17) opens and closes an access port (18) of the tank (32) of the humidification unit (30). The openable lid (17) is configured to tilt to the right with its lower part as a fulcrum. A pull-out opening (19) is formed in the upper part of the openable lid (17). A user places his / her hand on the pull-out opening (19) and pulls out the upper part of the openable lid (17) to the right (front side). This causes the upper part of the openable lid (17) to tilt to the right, opening the access port (18). This allows the user to remove the tank (32) from the casing (11) through the access port (18).

[0029] The left side plate (11f) is formed with a third suction port (20). The third suction port (20) is rectangular in shape, and is formed in the lower part of the left side plate (11f).

[0030] An air passage (P) is formed inside the casing (11). The first suction port (15), the second suction port (16), and the third suction port (20) form an inlet end of the air passage (P). The air outlet (12) forms an outlet end of the air passage (P).

The deodorizing filter (26) has a base material through which air can pass and an adsorbent material such as activated carbon supported on the base material.

[0037] (1-8) Humidification unit The humidification unit (30) is disposed between the deodorizing filter (26) and the air outlet (12). The humidification unit (30) is disposed in a humidification space (31) located at an upper portion of the air passage (P). The humidification unit (30) adds water to the air flowing through the air passage (P). The humidification unit (30) includes a tank (32), a water tray (33), and a humidification mechanism (40).

[0038] The tank (32) is a container for storing water for humidification. The tank (32) appropriately supplies the water therein to the water tray (33). The tank (32) is configured to be able to be inserted into and removed from the casing (11) through the above-mentioned access opening (18).

[0039] The water tray (33) stores the water supplied from the tank (32). The water tray (33) constitutes a water storage unit that stores water to be supplied to the water absorbing member (70) of the humidification mechanism (40). The water tray (33) is a container that is open at the top.

[0040] (2) Overall configuration of the humidification mechanism The humidification mechanism (40) humidifies water flowing through the air passage (P). The humidification mechanism (40) includes a drive mechanism (41), a drive shaft (42) driven by the drive mechanism (41), a shaft support (43) that supports the drive shaft (42), and a humidification rotor (44) connected to the drive shaft (42). The humidification rotor (44) divides the humidification space (31) into a primary space (31a) and a secondary space (31b). The primary space (31a) is formed upstream of the humidification rotor (44). The secondary space (31b) is formed downstream of the humidification rotor (44). Air passing through the humidification mechanism (40) flows from the primary space (31a) to the secondary space (31b) via the humidification rotor (44).

[0041] As shown in Fig. 2, the drive mechanism (41) is disposed in the primary space (31a). In this embodiment, the drive mechanism (41) is formed by a motor. The drive shaft (42) extends horizontally to the right from the drive mechanism (41). The drive shaft (42) is connected to the central axis of a rotation frame (45) of the humidification rotor (44).

[0042] The humidification mechanism (40) of this embodiment is provided with two shaft supports (43). One of these shaft supports (43) is located in the primary space (31a), and the other is located in the secondary space (31b). Each shaft support (43) rotatably supports a drive shaft (42) at its upper end. The shaft supports (43) of this embodiment are formed integrally with the water tray (33).

[0043] (3) Humidification rotor The configuration of the humidification rotor (44) will be described with reference to Fig. 2 to Fig. 13. In the following description, the terms "axial direction," "radial direction," "circumferential direction," and "rotational direction" generally refer to the axial direction, radial direction, circumferential direction, and rotational direction of the rotating frame (45), respectively. The "axial direction" refers to the direction in which the rotating axis (X), which is the center of rotation of the rotating frame (45) shown in Fig. 3, extends.

[0044] The humidification rotor (44) imparts water contained in the water absorption member (70) to the air in the humidification space (31). The humidification rotor (44) has a rotating frame (45) rotated by the drive mechanism (41) and a water absorption member (70) held in the rotating frame (45). The rotating frame (45) is made of a resin material. As shown in FIGS. 3 and 4, the rotating frame (45) has a first frame (50) and a second frame (60). The water absorption member (70) is held inside the rotating frame (45) by being sandwiched between the first frame (50) and the second frame (60).

[0045] The rotating frame (45) is provided with buckets (80A, 80B) and a spout (92). The buckets (80A, 80B) are water supply members for drawing up water from within the water tray (33) and supplying the drawn up water to the water absorption member (70). The spout (92) is an opening for pouring the water drawn up by the buckets (80A, 80B) into the water absorption member (70). The spout (92) connects the interior of the buckets (80A, 80B) to the water absorption member (70).

[0046] The buckets (80A, 80B) are configured to alternately move between a first position where they are immersed in the water inside the water tray (33) as the rotating frame (45) rotates and a second position where the water in the buckets (80A, 80B) is supplied to the water absorbent member (70) through the spout (92).

[0047] (3-1) First slot The first frame (50) is located on the upstream side of the air passage (P) of the rotary frame (45). The first frame (50) is located on the primary space (31a) side. The first frame (50) has a first boss portion (51) to which the drive shaft (42) is fixed, an annular first frame body (52), and a plurality of first ribs (53) connecting the first boss portion (51) and the first frame body (52).

[0048] The first boss portion (51) is located at the center of the rotary frame (45). The first ribs (53) extend radially outward from the first boss portion (51) toward the first frame body (52). The first ribs (53) are arranged at equal intervals in the circumferential direction.

[0049] 5, the first frame body (52) is formed in an annular shape coaxial with the rotation axis (X) of the rotary frame (45). The first frame body (52) has a base portion (52a) in the shape of a circular plate. The thickness direction of the base portion (52a) corresponds to the axial direction.

[0050] The first frame body (52) is composed of a first part (C1) and a plurality of second parts (C2) that are configured separately from the first part (C1). The first part (C1) and each of the second parts (C2) are resin molded products composed of different parts. The first part (C1) and each of the second parts (C2) are manufactured by injection molding in a mold. The first part (C1) is the portion of the first frame body (52) excluding the second part (C2). The first frame body (52) is configured by attaching each of the second parts (C2) to the first part (C1).

[0051] The multiple buckets (80A, 80B) include a first bucket (80A) provided on the first component (C1) and a second bucket (80B) each formed of a second component (C2). The first bucket (80A) is an example of a first water supply member (80A). The second bucket (80B) is an example of a second water supply member (80B). The second bucket (80B) is detachable from the rotary frame (45). The second bucket (80B) is attached to an attachment portion (100) provided on the base portion (52a). The attachment portion (100) will be described in detail below.

[0052] The rotary frame (45) of the present embodiment is provided with six first buckets (80A) and six second buckets (80B). The six first buckets (80A) are arranged at equal intervals along the circumferential direction of the first frame body (52). The second bucket (80B) is arranged between two first buckets (80A) adjacent to each other in the circumferential direction. In other words, in the rotary frame (45), the first buckets (80A) and the second buckets (80B) are arranged alternately in the circumferential direction.

[0053] (3-2) Second slot The second frame (60) is located on the downstream side of the air passage (P) of the rotary frame (45). The second frame (60) is located closer to the secondary space (31b) than the first frame (50). The second frame (60) has a second boss portion (61) to which the drive shaft (42) is fixed, an annular second frame body (62), and a plurality of second ribs (63) connecting the second boss portion (61) and the second frame body (62).

[0054] The second boss portion (61) is located at the center of the rotary frame (45). The second ribs (63) extend radially outward from the second boss portion (61) toward the second frame body (62). The second ribs (63) are arranged at equal intervals in the circumferential direction.

[0055] The second frame body (62) is formed in an annular shape coaxial with the rotation axis (X) of the rotary frame (45).

[0056] As shown in FIG. 4, the second frame (60) is provided with a plurality of pressing plates (64). The second frame (60) of this embodiment is provided with 12 pressing plates (64), but this number is merely an example. The pressing plates (64) are formed in a plate shape protruding from the second frame body (62) toward the first frame (50). The pressing plates (64) are arranged at equal intervals in the circumferential direction. The pressing plates (64) include a first pressing plate (64A) provided with a second claw (65) and a second pressing plate (64B) not having a second claw (65). The first pressing plate (64A) and the second pressing plate (64B) are arranged alternately in the circumferential direction. The second claw (65) of the first pressing plate (64A) is hooked onto a second water supply port (55) formed in the first frame body (52). This causes the first frame (50) and the second frame (60) to be fixed to each other.

[0057] The second frame (60) is provided with a plurality of retaining portions (66). In this embodiment, the second frame (60) is provided with 12 retaining portions (66), but this number is merely an example. The retaining portions (66) are provided on the inner edge of the second frame body (62). The retaining portions (66) are arranged at equal intervals in the circumferential direction. The retaining portions (66) constitute members for fixing the water-absorbing member (70) inside the rotating frame (45).

[0058] (3-3) Water-absorbing material The water-absorbing member (70) is formed in a disk shape coaxial with the rotation axis (X) of the rotary frame (45). The thickness direction of the water-absorbing member (70) corresponds to the axial direction or the air flow direction. Air passes through the water-absorbing member (70) in the axial direction of the rotary frame (45). The water-absorbing member (70) is made of a resin material having water-absorbing properties. The water-absorbing member (70) has a disk portion (71) and a flange portion (72) extending radially outward from the outer circumferential surface of the disk portion (71). A shaft opening (73) through which the drive shaft (42) passes is formed in the center of the disk portion (71).

[0059] 7, a first ventilation surface (74) is formed at one axial end of the water absorption member (70), and a second ventilation surface (75) is formed at the other axial end of the water absorption member (70). The first ventilation surface (74) corresponds to the surface of the water absorption member (70) that is upstream of the air flow. The second ventilation surface (75) corresponds to the surface of the water absorption member (70) that is downstream of the air flow.

[0060] A welded portion (76) is formed on the outer peripheral surface of the disk portion (71) of the water-absorbent member (70). The welded portion (76) is formed around the entire outer peripheral surface of the water-absorbent member (70). The welded portion (76) is formed by melting a water-absorbing material and then solidifying the material. On the other hand, the welded portion (76) is not formed on the first ventilation surface (74) or the second ventilation surface (75) of the water-absorbent member (70). Therefore, the first ventilation surface (74) and the second ventilation surface (75) of the water-absorbent member (70) have higher air and water permeability than the outer peripheral surface of the water-absorbent member (70).

[0061] As shown in Figs. 4 and 7, a pair of grooves (77, 78) is formed on the outer edge of the disk portion (71) of the water absorption member (70) so as to sandwich the flange portion (72). In other words, the pair of grooves (77, 78) is composed of a first groove (77) on the first ventilation surface (74) side and a second groove (78) on the second ventilation surface (75) side. The pair of grooves (77, 78) is formed in a concave shape recessed radially inward from the outer edge of the disk portion (71). The disk portion (71) is provided with six pairs of grooves (77, 78) at equal intervals in the circumferential direction. The number of pairs of grooves (77, 78) is merely an example. The disk portion (71) is formed with an insertion hole (79) extending in the axial direction so as to communicate the pair of grooves (77, 78). The insertion hole (79) is provided for each pair of grooves (77, 78). The pair of grooves (77, 78) is located radially inward of the welded portion (76).

[0062] (3-4) Bucket configuration The configurations of the first bucket (80A) and the second bucket (80B) will be described with reference to Figs. 8 to 10. The second bucket (80B) is attached to the attachment portion (100). In the following, the configuration common to the first bucket (80A) and the second bucket (80B) will be described as "buckets (80A, 80B)." The configuration of the second bucket (80B) that differs from the first bucket (80A) will be described later.

[0063] The buckets (80A, 80B) form a water container having an opening (80a). A water storage space (S) is formed inside the buckets (80A, 80B). The water storage space (S) is closed by the buckets (80A, 80B) except for the opening (80a). The opening (80a) of the buckets (80A, 80B) faces the rotation direction of the rotary frame (45). In other words, the buckets (80A, 80B) are formed in a bottomed cylindrical shape with one end on the rotation direction side open and the other end opposite to the rotation direction closed. The buckets (80A, 80B) of this embodiment extend in the circumferential direction of the rotary frame (45).

[0064] The buckets (80A, 80B) have 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 on the radially outer side of the buckets (80A, 80B). The second plate portion (82) is located on the radially inner side of the buckets (80A, 80B). The third plate portion (83) is located on the axial side of the buckets (80A, 80B) facing the water absorption member (70). The fourth plate portion (84) is located on the axially opposite side of the buckets (80A, 80B) from the water absorption member (70).

[0065] In the first bucket (80A), the fourth plate portion (84) is formed by part of the base (52a) of the first frame body (52). The first bucket (80A) is positioned upstream of the water absorption member (70) in the axial air flow. In other words, the first bucket (80A) is formed on the side of the base (52a) that faces the secondary space (31b).

[0066] The third plate portion (83) has 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 farther from the fourth plate portion (84) in the axial direction than the third wall (83c). The third wall (83c) is continuous with a radially inner end of the second wall (83b) and a radially inner end of the first wall (83a).

[0067] 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 as to approach the rotation axis (X) as it moves toward the opposite side to the water absorption member (70). Strictly speaking, the "cross section passing through the rotation axis (X)" means a cross section on an imaginary plane that passes through the rotation axis (X) and extends in the same direction as the rotation axis (X).

[0068] 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).

[0069] 10, the second plate portion (82) is inclined so as to approach the rotation axis (X) in the direction of rotation, which makes it easier to guide water from the water storage space (S) to the openings (80a) of the buckets (80A, 80B) when the buckets (80A, 80B) move upward relative to the rotary frame (45).

[0070] (3-5) Spout configuration The spout (92) has a first spout (92A) and a second spout (92B). The first spout (92A) corresponds to the first bucket (80A). The second spout (92B) corresponds to the second bucket (80B). Since the first spout (92A) and the second spout (92B) have the same configuration, The first spout (92A) and the second spout (92B) are provided on the guide portion (90). The guide portion (90) is a portion that guides water flowing out from the openings (80a) of the buckets (80A, 80B) to the water absorption member (70). The guide portion (90) is provided on the rotary frame (45) so as to be adjacent to the openings (80a) of the buckets (80A, 80B) in the direction of rotation. The guide portion (90) is located radially inward relative to the openings (80a) of the buckets (80A, 80B). The guide portion (90) has a recess (91) that is recessed radially inward.

[0071] The first spout (92A) and the second spout (92B) are formed inside the recess (91). The first spout (92A) and the second spout (92B) open toward the water-absorbent member (70). Specifically, the first spout (92A) and the second spout (92B) open toward the first ventilating surface (74) of the water-absorbent member (70). The first ventilating surface (74) is the surface of the water-absorbent member (70) on the axial end side.

[0072] By opening the first spout (92A) and the second spout (92B) toward the first ventilation surface (74) of the water absorbent member (70), the water in the buckets (80A, 80B) is more likely to come into contact with the air passing through the water absorbent member (70), thereby improving the humidification capacity of the water absorbent member (70).

[0073] The recess (91) has 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) faces the first side wall (93). The first wall (83a) and the second wall (83b) extend in the radial direction when viewed in the axial direction. The bottom wall (95) extends in the circumferential direction from a radially inner end of the first side wall (93) to a radially inner end of the second side wall (94).

[0074] As shown in FIGS. 9 and 10, the guide portion (90) has a guide plate (99). The guide plate (99) is disposed on the circumferentially opposite side of the opening (80a) of the bucket (80A, 80B) across the spout (92). The guide plate (99) has a flat surface (99a) that faces the opening (80a) of the bucket (80A, 80B). The flat surface (99a) of the guide plate (99) faces the opposite side to the rotation direction. The flat surface of the guide plate (99) is located radially outward and at the rear side in the rotation direction of the second wall (83b). Water flowing out from the opening (80a) of the bucket (80A, 80B) collides with the flat surface (99a) of the guide plate (99). The colliding water changes direction from the radial direction to the axial direction and is guided to the spout (92).

[0075] (3-6) Configuration of the holding part 7 and 11, the second frame (60) is provided with a holding portion (66). The holding portion (66) is provided corresponding to each spout (92). The holding portion (66) has a water shielding wall (66a), a fixing pin (66b) protruding from the water shielding wall (66a) toward the water absorbent member (70), and a fixing wall (66c) surrounding the fixing pin (66b).

[0076] The water shielding wall (66a) is located on the axially opposite side of the spout (92) with the water absorption member (70) in between. The water shielding wall (66a) faces the spout (92) via the water absorption member (70). The water shielding wall (66a) and the water absorption member (70) overlap in the axial direction. The area of ​​the surface of the water shielding wall (66a) facing the spout (92) is larger than the opening area of ​​the spout (92). The water shielding wall (66a) prevents water supplied from the spout (92) toward the water absorption member (70) from passing through the water absorption member (70). This makes it possible to increase the amount of water held inside the water absorption member (70).

[0077] The fixing pin (66b) is located at the center of the surface of the water impermeable wall (66a) facing the water absorbent member (70). The fixing pin (66b) is formed in a trapezoidal cone shape whose outer diameter decreases toward the water absorbent member (70). The fixing pin (66b) is inserted into an insertion hole (79) of the water absorbent member (70). The fixing pin (66b) fits into the insertion hole (79), thereby fixing the water absorbent member (70) to the second frame (60).

[0078] The fixed wall (66c) is formed in a U-shape with an open radially outward side when viewed in a cross section perpendicular to the axial direction. An annular flange (67) protruding in the axial direction is formed on the surface of the second frame body (62) facing the water absorption member (70). Two radially outward ends of the fixed wall (66c) are continuous with the inner peripheral surface of the flange (67). The fixed wall (66c) fits into the second groove (78) of the water absorption member (70). The fixed wall (66c) fits into the water absorption member (70), thereby fixing the water absorption member (70) to the second frame (60).

[0079] As described above, the water impermeable wall (66a) not only serves to prevent water from passing through the water absorbent member (70), but also serves as a member for fixing the water absorbent member (70).

[0080] (3-7) Water supply port As shown in Fig. 8, a plurality of first water inlet ports (57) and a plurality of second water inlet ports (55) are formed in the base portion (52a) of the first frame body (52). The first water inlet port (57) is an opening for supplying water to the first bucket (80A). The second water inlet port (55) is an opening for supplying water to the second bucket (80B).

[0081] The first water inlet (57) is formed in a circular shape. The second water inlet (55) is formed in a rectangular shape. The first water inlet (57) is located forward of the opening (80a) of the first bucket (80A) in the direction of rotation. The second water inlet (55) is located forward of the opening (80a) of the second bucket (80B) in the direction of rotation.

[0082] When the first water supply port (57) is immersed in the water in the water tray (33), the water enters the inside of 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 inside of the second bucket (80B) through the second water supply port (55).

[0083] The second water inlet (55) serves both to supply water to the second bucket (80B) and to fix the second frame (60) to the base (52a).

[0084] (3-8) Detailed configuration of the mounting part As shown in Figs. 12 and 13, the rotating frame (45) has an attachment portion (100) to which a removable second bucket (80B) is attached. The attachment portion (100) is formed so that the first spout (92A) and the second spout (92B) face in the same direction relative to the water-absorbing member (70). Specifically, the attachment portion (100) is disposed on a flat portion of the base (52a) of the first frame body (52) that faces the secondary space (31b). In other words, the attachment portion (100) is formed on the surface of the base (52a) of the first frame body (52) on the side where the first bucket (80A) is provided. As a result, the first bucket (80A) and the second bucket (80B) are provided on the portion of the base (52a) that faces the secondary space (31b).

[0085] The mounting portions (100) are configured so that one second bucket (80B) is attached to each mounting portion (100). In this embodiment, six mounting portions (100) are arranged at equal intervals along the circumferential direction of the first frame body (52). The mounting portions (100) are arranged between two first buckets (80A) that are adjacent to each other in the circumferential direction of the first frame body (52). Specifically, the mounting portion (100) is arranged in a region of the base (52a) between one opening (80a) of two first buckets (80A) that are adjacent to each other in the circumferential direction and the guide plate (99) of the other.

[0086] The mounting portion (100) is configured such that, with the second bucket (80B) attached to the mounting portion (100), the opening (80a) of the second bucket (80B) faces the rotational direction of the humidification rotor (44). In other words, with the second bucket (80B) attached to the mounting portion (100), the opening (80a) of the first bucket (80A) and the opening (80a) of the second bucket (80B) face in the same circumferential direction.

[0087] The mounting portion (100) has a hook structure (54A, 54B) that engages with the second bucket (80B). The hook structure (54A, 54B) has 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 on the base (52a). Engagement portions (110, 120) provided on the second bucket (80B) engage with the first mounting hole (54A) and the second mounting hole (54B).

[0088] The first mounting hole (54A) is formed in a generally rectangular shape when viewed in the axial direction. Specifically, the first mounting hole (54A) is defined by a pair of first radial sides (M1) extending generally in the radial direction and a pair of first circumferential sides (N1) perpendicular to the first radial sides. The first mounting hole (54A) is located rearward in the rotational direction of the second mounting hole (54B). The first mounting hole (54A) is located near the first water supply port (57) of the first bucket (80A).

[0089] The second mounting hole (54B) is formed in a generally rectangular shape when viewed in the axial direction. Specifically, the second mounting hole (54B) is defined by a pair of second radial sides (M2) extending generally in the radial direction and a pair of second circumferential sides (N2) perpendicular to the second radial sides. The second mounting hole (54B) is disposed near the guide plate (99) of the first bucket (80A). In other words, the second mounting hole (54B) is formed near the other circumferential end of the mounting region in the base portion (52a). A part of the second mounting hole (54B) communicates with the second water supply port (55). Specifically, the second mounting hole (54B) is disposed on the counter-rotational side and radially inward side of the second water supply port (55).

[0090] (3-9) Details of the second bucket structure The second bucket (80B) of this embodiment will be described with reference to Fig. 14. In the following, the fourth plate portion (84) of the second bucket (80B) and the mounting area face each other. The structure different from the first bucket (80A) will be described.

[0091] The second bucket (80B) has a first engagement portion (110) and a second engagement portion (120). The first engagement portion (110) and the second engagement portion (120) protrude in the axial direction toward an attachment region of the fourth plate portion (84). The first engagement portion (110) engages with the first attachment hole (54A). The second engagement portion (120) engages with the second attachment hole (54B). The first engagement portion (110) and the second engagement portion (120) are formed in a substantially L-shape when viewed from the first plate portion (81) side.

[0092] The first engagement portion (110) is provided on an end of the fourth plate portion (84) opposite to the position of the opening (80a). The first engagement portion (110) is disposed on the fourth plate portion (84) closer to the second plate portion (82) than to the first plate portion (81). The first engagement portion (110) has a first mounting plate portion (111) and a first hook portion (112). The first mounting plate portion (111) rises from the fourth plate portion (84). The plate surface of the first mounting plate portion (111) is aligned along the first radial side (M1) of the first mounting hole (54A). The radial width of the first mounting plate portion (111) is approximately the same as the length of the first radial side (M1) of the first mounting hole (54A). The first hook portion (112) is formed so as to extend from the tip of the first mounting plate portion (111) in the counter-rotation direction (the side opposite to the position of the opening (80a)) and then bend back toward the fourth plate portion (84). In other words, the tip of the first hook portion (112) faces the fourth plate portion (84).

[0093] The second engagement portion (120) is provided at an end of the fourth plate portion (84) on the opening (80a) side. The second engagement portion (120) is disposed on the fourth plate portion (84) closer to the second plate portion (82) than to the first plate portion (81). The second engagement portion (120) has a second mounting plate portion (121) and a second hook portion (122). The second mounting plate portion (121) rises from the fourth plate portion (84). The plate surface of the second mounting plate portion (121) is aligned along the second radial side (M2) of the second mounting hole (54B). The radial width of the second mounting plate portion (121) is approximately the same length as the second radial side (M2) of the second mounting hole (54B). The second hook portion (122) is formed so as to extend from the tip of the second mounting plate portion (121) in the counter-rotation direction (the side opposite to the position of the opening (80a)) and then bend back toward the fourth plate portion (84). In other words, the tip of the second hook portion (122) faces the fourth plate portion (84).

[0094] (4) Driving behavior The operation of the air purifier (10) will now be described.

[0095] (4-1) Basic operation of air purifier 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 driven. As shown in Fig. 2, air from the target space is sucked into the air passage (P) through each of the first suction inlet (15), the second suction inlet (16), and the third suction inlet (20). The air sucked through the second suction inlet (16) and the third suction inlet (20) passes through each prefilter (21). The prefilter (21) collects relatively large dust particles in the air.

[0096] The air that has passed 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 odorous and harmful components in the air. Viruses and bacteria in the air are killed by ultraviolet light emitted by the UV irradiation unit (24).

[0097] The air then passes through the HEPA filter (25) and the deodorizing filter (26), and then flows into the humidification space (31). The air in the humidification space (31) passes axially through the humidification rotor (44). During this process, water from the water-absorbing member (70) is added to the air. The air humidified by the humidification rotor (44) is supplied to the target space through the air outlet (12).

[0098] (4-2) Humidification unit operation When the air purifier (10) described above is in operation, the humidification unit (30) performs the following operation.

[0099] The drive mechanism (41) rotates the drive shaft (42). This causes the humidification rotor (44) to rotate about the rotation axis (X). When the rotary frame (45) rotates, the buckets (80A, 80B) revolve around the rotation axis (X). When the buckets (80A, 80B) move below the rotary frame (45) and enter the water in the water tray (33), water enters the water storage space (S) of the buckets (80A, 80B). When the buckets (80A, 80B) move upward and out of the water in the water tray (33), water is pumped into the water storage space (S) of the buckets (80A, 80B).

[0100] When the buckets (80A, 80B) move further upward and reach a predetermined first angular position forward of the upper end of the rotary frame (45), the water in the water storage space (S) starts to flow down toward the opening (80a).

[0101] As the rotating frame (45) continues to rotate, the water that has passed through the openings (80a) of the buckets (80A, 80B) is guided by the guide portion (90) to the spout (92). Specifically, in the guide portion (90), the water that has passed through the openings (80a) is sent along the bottom surface (97) to the spout (92). The water that has passed through the spout (92) is supplied to the inside of the water-absorbent member (70) through the first ventilation surface (74) of the water-absorbent member (70). The water in the water-absorbent member (70) is applied to the air flowing through the humidification space (31).

[0102] As the rotary frame (45) rotates further, the buckets (80A, 80B) move to the lower side of the rotary frame (45) and again enter the water in the water tray (33). The above-mentioned operation is continuously repeated.

[0103] (5) Manufacturing method of the rotary frame A method for manufacturing the rotary frame (45) will be described with reference to Figures 15 to 17. In this embodiment, the method includes an attachment step of attaching the second bucket (80B) to the attachment portion (100) of the first frame (50), and a fitting step of fitting the second frame (60) into the first frame (50) after the second bucket is attached. These steps are performed by human operation. Note that the water absorbing member (70) is provided on the first frame (50) in advance, but may be provided on the first frame (50) after the attachment step.

[0104] In step S11, the user performs the mounting process. In the mounting process, the first engagement portion (110) of the second bucket (80B) is hooked into the first mounting hole (54A) and the second engagement portion (120) is hooked into the second mounting hole (54B). Specifically, the first engagement portion (110) is pushed into the first mounting hole (54A) and the second engagement portion (120) is pushed 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 sandwiched between the two first circumferential sides (N1) of the first mounting hole (54A). Similarly, the second mounting plate portion (121) is sandwiched between the two second circumferential sides (N2) of the second mounting hole (54B).

[0105] Thereafter, the second bucket (80B) is slid in the counter-rotational direction relative to the first frame (50). As a result, the first mounting plate portion (111) comes into contact with one side of the first radial side (M1) of the first mounting hole (54A) that is in the counter-rotational direction. Similarly, the second mounting plate portion (121) comes into contact with one side of the second radial side (M2) of the second mounting hole (54B) that is in the counter-rotational direction. In this state, the tip of the first hook portion (112) and the tip of the second hook portion (122) are each located above the surface of the base portion (52a) that faces the primary space (31a) (see FIG. 16). In other words, the first hook portion (112) is hooked into the first mounting hole (54A), and the second hook portion (122) is hooked into the second mounting hole (54B). In this manner, "engagement" refers to the hook portions (112, 122) being caught in the mounting holes (54A, 54B).

[0106] In this manner, the first engagement portion (110) is fixed to the first mounting hole (54A) and the second engagement portion (120) is fixed to the second mounting hole (54B), thereby preventing the second bucket (80B) from falling off 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 preventing the second bucket (80B) from shifting in the circumferential direction.

[0107] In addition, in the process in which the second bucket (80B) that has scooped up water moves in the rotational direction and rises, the second bucket (80B) is relatively heavy because it contains water. However, because the first hook portion (112) is hooked on one of the pair of first radial sides (M1) that is on the counter-rotational side, the weight of the second bucket (80B) containing water makes it difficult for the first hook portion (112) to come off the first mounting hole (54A). Similarly, because the second hook portion (122) is hooked on one of the pair of second radial sides (M2) that is on the counter-rotational side, the weight of the second bucket (80B) containing water makes it difficult for the second hook portion (122) to come off the second mounting hole (54B). In this way, by forming both the first hook portion (112) and the second hook portion (122) to extend in the counter-rotation direction, even if the second bucket (80B) becomes heavy as a result of absorbing water, it is possible to prevent the second bucket (80B) from detaching from the first frame body (52) during movement.

[0108] In step S12, the user performs a fitting process. In the fitting and fixing, the second claws (65) of the second frame (60) are engaged with the second water supply ports (55) of the first frame body (52). Specifically, the second frame (60) is brought closer to the first frame (50) in the axial direction, and the six second claws (65) are inserted into the second water supply ports (55). After that, the second claws (65) are hooked onto the second water supply ports (55) (see FIG. 17). This makes it difficult for the second frame (60) to shift circumferentially relative to the first frame (50) and the second frame (60) to separate from the first frame (50) in the axial direction. In step S12, "engagement" refers to the second claws (65) being hooked onto the second water supply ports (55).

[0109] (6) Features (6-1) Feature 1 In the air purifier (10) of this embodiment, the first bucket (80A) is formed integrally with the rotary frame (45). The rotary frame (45) has an attachment portion (100) to which a detachable second bucket (80B) is attached.

[0110] Thus, by attaching the second bucket (80B) to the attachment portion (100) in addition to the first bucket (80A) integrally formed with the rotary frame (45), the number of buckets (80A, 80B) can be increased.

[0111] In addition, since the rotating frame (45) is already equipped with the first bucket (80A), a minimum amount of water can be supplied to the water absorption member (70) per rotation of the humidification rotor (44), and by attaching the second bucket (80B), the amount of water supplied to the water absorption member (70) can be increased.

[0112] In addition, by adjusting the number of second buckets (80B) attached to the attachment portion (100), the amount of water supplied to the water absorbing member (70) per rotation of the humidification rotor (44) can be adjusted, thereby enabling fine adjustment of the amount of humidification of the room air.

[0113] Furthermore, when the buckets (80A, 80B) are integrally formed with the rotary frame (45), there is a manufacturing problem in that if the number of buckets (80A, 80B) is increased, the molded product cannot be removed from the metal mold. Therefore, there is a limit to the number of buckets (80A, 80B) that can be provided in an integrally molded product. However, in this embodiment, an attachment portion (100) for attaching the second bucket (80B) to the rotary frame (45) formed integrally with the first bucket (80A) is provided. As a result, even if the rotary frame (45) is formed integrally with the buckets (80A, 80B), the second bucket (80B) can be attached later, and the number of buckets (80A, 80B) can be increased.

[0114] (6-2) Feature 2 In the air purifier (10) of this embodiment, the attachment portion (100) is formed so that the first spout (92A) and the second spout (92B) face in the same direction relative to the water absorbent member (70).

[0115] In this embodiment, the attachment portion (100) is provided on the primary space (31a) side of the base (52a), and therefore the second bucket (80B) is installed on the same side of the primary space (31a) of the base (52a) as the first bucket (80A). This allows the first spout (92A) and the second spout (92B) to face in the same direction, and the first bucket (80A) and the second bucket (80B) can supply water to the water absorbent member (70) from the same direction.

[0116] If water flows out toward the secondary space (31b), there is a risk that the water will be carried by the air flow and splash around. In this embodiment, however, the first spout (92A) and the second spout (92B) cause the water to flow out toward the primary space (31a), thereby preventing such splashing.

[0117] (6-3) Feature 3 In the air purifier (10) of this embodiment, the first bucket (80A) is located upstream of the water absorbent member (70) in the axial airflow.

[0118] This makes it possible to pour water into the water absorption member (70) by utilizing the air flow toward the water absorption member (70), thereby making it possible to prevent water from splashing while being supplied to the water absorption member (70).

[0119] (6-4) Feature 4 In the air purifier (10) of this embodiment, the attachment portion (100) has hook structures (54A, 54B) that engage with the second bucket (80B).

[0120] As a result, the second bucket (80B) can be easily attached to and detached from the mounting portion (100) by simply hooking the first engagement portion (110) into the first mounting hole (54A) and the second engagement portion (120) into the second mounting hole (54B).

[0121] (6-5) Feature 5 In the air purifier (10) of this embodiment, the first buckets (80A) and the attachment portions (100) are arranged alternately along the outer periphery of the rotary frame (45).

[0122] This allows the second bucket (80B) to be attached between the first buckets (80A) adjacent to each other in the circumferential direction of the rotary frame (45). As a result, the interval at which water is supplied to the water absorption member (70) can be made shorter than when the second bucket (80B) is not attached to the rotary frame (45). As a result, the air passing through the water absorption member (70) can be sufficiently humidified.

[0123] (6-6) Feature 6 In the air purifier (10) of the present embodiment, the rotary frame (45) has six first buckets (80A).

[0124] This ensures that the water absorbent member (70) can retain a minimum amount of water even when the second bucket (80B) is not attached.

[0125] (7) Other embodiments The above embodiment may be configured as follows.

[0126] Although six first buckets 80A are formed in the rotary frame 45 in the above embodiment, the number of first buckets 80A is not limited to six, and may be six or more, or five or less.

[0127] Although the first frame body (52) has been described as being composed of the first part (C1) and the second part (C2), this is not limiting. The first frame body (52) may be configured not to include the second part (C2). That is, the rotating frame (45) may include 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 have a rotating frame set including the rotating frame (45) with the first bucket (80A) and the second bucket (80B). [Industrial Applicability]
