[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference symbols and the description will not be repeated. For convenience of explanation, a three-dimensional orthogonal coordinate system (X, Y, Z) is appropriately depicted in the drawings. In the drawings, the X-axis and Y-axis are parallel to the horizontal direction, and the Z-axis is parallel to the vertical direction.

[0011] [Embodiment 1] A humidifier 100 according to an embodiment of the present invention will be described with reference to Figures 1 to 5. First, the humidifier 100 will be described with reference to Figures 1 to 3. The humidifier 100 humidifies air by an evaporation method.

[0012] FIG. 1 is a diagram showing a humidifier 100 according to this embodiment. As shown in FIG. 1, the humidifier 100 includes a housing 1 and an operation panel 3. The housing 1 has, for example, a substantially rectangular parallelepiped shape. The operation panel 3 is disposed on an upper surface 1a of the housing 1. The operation panel 3 receives inputs for operating the humidifier 100 and notifies the user of the status of the humidifier 100. The humidifier 100 has an air outlet 5 for blowing out air. The air outlet 5 is disposed on the upper surface 1a of the housing 1.

[0013] Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. Fig. 2 is a side cross-sectional view of the humidifier 100. In Fig. 2, the air flow is indicated by white arrows. Fig. 3 is an enlarged view of the humidifying filter unit 13 of the humidifier 100 shown in Fig. 1.

[0014] 2, the humidifier 100 further includes a deodorizing filter 9, a dust collecting filter 11, a humidifying filter unit 13, a rotating shaft 15, a pair of shaft supports 17, a water tank 19, a drive mechanism 21, a blower 23, and a detection unit 30. The housing 1 accommodates the deodorizing filter 9, the dust collecting filter 11, the humidifying filter unit 13, the rotating shaft 15, the pair of shaft supports 17, the water tank 19, the drive mechanism 21, the blower 23, and the detection unit 30. The humidifier 100 also has a plurality of suction ports 7 for sucking in air. The suction ports 7 are arranged on the rear surface 1b of the housing 1.

[0015] As shown in Fig. 2, the detection unit 30 detects the rotational position of the humidifying filter unit 13. Specifically, the detection unit 30 detects the rotation of the humidifying filter unit 13 by detecting a detectable member described below. The detection unit 30 in this embodiment is a Hall element that detects magnetism. The Hall element outputs a signal indicating the approach of a magnet that generates magnetism at a time interval corresponding to the rotational speed of the humidifying filter unit 13. The detection unit 30 is attached to the side of a storage unit that stores the water tub 19.

[0016] The blower 23 takes in air through the multiple suction inlets 7. The blower 23 then blows out the air through the outlet 5. Therefore, an air passage PS that connects the multiple suction inlets 7 and the outlet 5 is formed inside the housing 1. Specifically, the blower 23 includes a fan 23a and a fan motor 23b. The fan motor 23b drives the fan 23a to rotate it.

[0017] The deodorizing filter 9 adsorbs odorous components in the air. The odorous components are, for example, acetaldehyde, ammonia, or acetic acid. The deodorizing filter 9 is disposed opposite the multiple intake ports 7. The deodorizing filter 9 has a configuration in which activated carbon is dispersed in a nonwoven fabric, for example, and adsorbs or removes odorous components in the air.

[0018] The dust collection filter 11 captures or removes fine dust particles in the air. The dust collection filter 11 is disposed opposite the plurality of suction ports 7 via the deodorizing filter 9. The dust collection filter 11 is, for example, a HEPA (High Efficiency Particulate Air) filter.

[0019] The humidifying filter unit 13 is disposed on the air passage PS and is rotatable about a rotation axis AX. As shown in Fig. 2 and Fig. 3, the humidifying filter unit 13 includes a holder 131, a humidifying filter 133, a supply unit 140, and a detected member 301.

[0020] The detected member 301 is detected by the detection unit 30. The detected member 301 is a magnet. The detected member 301 is held by the holding unit 131. The detected member 301 is disposed in approximately the same position as the position where the supply unit 140 is disposed.

[0021] The holder 131 holds the humidifying filter 133 and the supply unit 140. The holder 131 has a substantially disk shape and is made of, for example, synthetic resin.

[0022] The humidifying filter 133 is disposed in the air passage PS downstream of the air inlet 7, the deodorizing filter 9, and the dust collecting filter 11. Specifically, the humidifying filter 133 is disposed between the blower 23 and the air inlet 7.

[0023] The supply unit 140 supplies water to the humidifying filter 133 .

[0024] The water tub 19 is disposed at the bottom of the housing 1 in correspondence with the humidifying filter 133. The water tub 19 stores water W to be supplied to the humidifying filter 133. The water tub 19 is made of, for example, synthetic resin. A portion of the humidifying filter 133 is located within the water tub 19 and immersed in the water W of the water tub 19. Specifically, when water W at a predetermined water level LV is stored in the water tub 19, a portion of the humidifying filter 133 is located within the water tub 19 and immersed in the water W of the water tub 19.

[0025] The rotating shaft 15 passes through the humidifying filter unit 13. The rotating shaft 15 is fixed to the rotation center of the humidifying filter unit 13. Specifically, the rotating shaft 15 is fixed to the rotation center of the holding portion 131. In other words, the rotating shaft 15 is disposed on the rotation axis line AX. The rotating shaft 15 has a substantially cylindrical shape.

[0026] The pair of shaft supports 17 support the rotating shaft 15 so as to be rotatable about the rotation axis AX. That is, the pair of shaft supports 17 support the humidifying filter unit 13 via the rotating shaft 15 so as to be rotatable about the rotation axis AX.

[0027] Specifically, the pair of shaft support parts 17 extend upward from the upper parts of a pair of side walls of the water tank 19. Each of the pair of shaft support parts 17 includes, for example, a U-shaped or circular support 17a. The pair of supports 17a rotatably support the rotating shaft 15. The support 17a may be, for example, a bearing.

[0028] The rotating shaft 15 may be fixed to a pair of shaft supports 17. In this case, the rotating shaft 15 supports the humidifying filter unit 13 so as to be rotatable about the rotation axis AX. That is, the rotating shaft 15 supports the holding part 131 so as to be rotatable. In this case, it is preferable that the holding part 131 has a bearing at the center of rotation.

[0029] The drive mechanism 21 abuts against the peripheral edge of the humidifying filter unit 13 to rotate the humidifying filter unit 13. Specifically, the drive mechanism 21 includes a drive gear 21a and a motor 21b. The rotation axis of the drive gear 21a is substantially parallel to the rotation axis line AX. The motor 21b drives the drive gear 21a to rotate the drive gear 21a.

[0030] On the other hand, the holding portion 131 includes a circular frame body 131a and a ring gear 131x. The ring gear 131x is formed on a circumference of an outer peripheral surface 1311 of the frame body 131a. The driving gear 21a meshes with the ring gear 131x. Therefore, when the driving gear 21a is rotated by the motor 21b, the holding portion 131 rotates about the rotation axis AX. As a result, the humidifying filter 133 rotates about the rotation axis AX together with the holding portion 131. In other words, when the driving gear 21a is rotated by the motor 21b, the humidifying filter unit 13 rotates about the rotation axis AX.

[0031] Drive mechanism 21 may include a roller instead of drive gear 21a. As long as humidifying filter unit 13 is rotatable about rotation axis AX, humidifier 100 does not need to include rotation shaft 15. For example, a plurality of rotors may be disposed in water tub 19, and the plurality of rotors may rotatably support humidifying filter unit 13.

[0032] 2 and 3, the humidifying filter unit 13 will now be described in detail.

[0033] As shown in FIGS. 2 and 3, the holding portion 131 includes a frame body 131a, a shaft insertion portion 131d, and a storage portion 131e.

[0034] Frame 131a has a circular shape. Frame 131a covers edge EG1 of humidifying filter 133 and is disposed outside humidifying filter 133. Frame 131a also covers edge EG3 of supply unit 140 and is disposed outside edge EG3 of supply unit 140. In other words, frame 131a holds humidifying filter 133. Frame 131a is disposed outside the first holding portion and the second holding portion.

[0035] The frame body 131a includes a plurality of first reinforcing members 131b, a second reinforcing member 131c, and a shaft insertion portion 131d. The plurality of first reinforcing members 131b extend radially from the shaft insertion portion 131d and are connected to the frame body 131a. As a result, the frame body 131a is reinforced by the plurality of first reinforcing members 131b.

[0036] The second reinforcing member 131c has a substantially annular shape and connects the multiple first reinforcing members 131b together, so that the multiple first reinforcing members 131b are reinforced by the second reinforcing member 131c.

[0037] The shaft insertion portion 131d has a substantially cylindrical shape, and is inserted into the through-hole 133c of the humidifying filter 133. The rotating shaft 15 (FIG. 2) is inserted into the shaft insertion portion 131d. In this embodiment, the rotating shaft 15 is fixed to the shaft insertion portion 131d. Note that the rotating shaft 15 may not be fixed to the shaft insertion portion 131d, and the shaft insertion portion 131d may have a bearing.

[0038] The storage section 131e stores the supply section 140. The storage section 131e has a non-circular shape. In this embodiment, the storage section 131e has a substantially D-shape when viewed from the front. In this embodiment, the front view indicates that the object is viewed from the direction in which the rotation axis line AX (FIG. 2) extends. Specifically, regarding the shape of the storage section 131e, the "non-circular shape" includes a straight line and a curved line. In other words, the storage section 131e has a substantially flat plate shape and a substantially arch shape. When the humidifier 100 is not driven, the storage section 131e is disposed at a position where it is stored in the water tank 19 (FIG. 2). As a result, when the humidifier 100 is not driven, the humidifying filter 133 is not immersed in the water W. The storage section 131e has the supply section 140 and the detected member 301. The storage section 131e is disposed at a position different from the humidifying filter 133 and inside the frame body 131a.

[0039] The humidifying filter 133 is water absorbent and has ventilation properties. That is, the humidifying filter 133 absorbs water from the water tank 19 and allows air to pass through. The air is humidified when it passes through the humidifying filter 133 that has absorbed water. In other words, the humidifying filter 133 functions as an evaporation filter. The humidifying filter 133 is disposed inside the frame 131a.

[0040] As shown in FIG. 3, the humidifying filter 133 is disposed around the rotation axis AX (FIG. 2). The humidifying filter 133 rotates about the rotation axis AX. A part of the humidifying filter 133 is immersed in the water W of the water tank 19. The blower 23 blows the air in the room in which the humidifying device 100 is installed from the inlet 7 to the water-absorbing humidifying filter 133. As a result, the water absorbed in the humidifying filter 133 is vaporized. Then, the blower 23 blows the air containing the vaporized water from the outlet 5 toward the room in which the humidifying device 100 is installed. As a result, the air in the room is humidified.

[0041] In this embodiment, the humidifying filter 133 has a pleated structure. Specifically, the humidifying filter 133 has a shape in which a sheet material is folded in an accordion-like shape. That is, the humidifying filter 133 has a zigzag shape in a side cross-sectional view. As a result, the surface area of ​​the humidifying filter 133 increases, and the water content increases. In this embodiment, the side cross-sectional view indicates a cross-section of the target object viewed from a direction perpendicular to the rotation axis AX (FIG. 2) and parallel to the horizontal direction. Note that the humidifying filter 133 does not have to be bellows-shaped and may have other shapes as long as it has water absorption and ventilation properties. For example, the humidifying filter 133 may have a honeycomb structure.

[0042] The shape of the humidifying filter 133 is non-circular. In this embodiment, the humidifying filter 133 has a substantially D-shape when viewed from the front. With respect to the shape of the humidifying filter 133, a "circular shape" includes straight lines and curved lines. In other words, the circular shape may be a substantially perfect circle or a substantially elliptical shape as long as it includes straight lines and curved lines.

[0043] When edge EG1 on the curved side of humidifying filter 133 is located at the lowest position, edge EG1 is immersed in the water W of aquarium 19. In other words, humidifying filter 133 absorbs water. When edge EG2 on the straight side of humidifying filter 133 is located at the lowest position and is approximately parallel to the water surface of aquarium 19, edge EG2 is not immersed in the water W of aquarium 19. In other words, humidifying filter 133 does not absorb water.

[0044] Specifically, the humidifier 100 is in a non-operated state when the detection unit 30 detects the detected member 301. When the humidifier 100 is in a non-operated state, the supply unit 140 is disposed at a position accommodated in the water tank 19 (FIG. 2). As a result, when the humidifier 100 is in a non-operated state, the humidifying filter 133 is not immersed in the water W and is not humidified.

[0045] The supply unit 140 draws up water from the water tank 19 and supplies the water to the humidifying filter 133. The humidifying filter 133 not only absorbs water stored in the water tank 19, but also receives water from the supply unit 140. As shown in FIG. 3, the supply unit 140 is held in the holder 131 together with the humidifying filter 133. Specifically, the supply unit 140 is housed inside the housing 131e. Therefore, the supply unit 140 and the humidifying filter 133 can be disposed in the holder 131 without increasing the outer diameter of the holder 131. In other words, the supply unit 140 can be disposed in the humidifying filter 133 by using a space that would not normally be used for humidification. As a result, the degree of freedom in product design can be improved.

[0046] Further, the detection target member 301 is accommodated in the accommodation section 131e. The supply section 140, the humidifying filter 133, and the detection target member 301 are arranged inside the outer edge of the holding section 131. Therefore, the supply section 140, the humidifying filter 133, and the detection target member 301 can be arranged in the holding section 131 without increasing the outer diameter of the holding section 131. That is, the supply section 140 and the detection target member 301 can be arranged in the vacant space of the accommodation section 131e. Therefore, it becomes easy to arrange the supply section 140 and the detection target member 301 in products of various sizes. As a result, the degree of freedom in product design can be improved. Furthermore, since the detection target member 301 is arranged in the accommodation section 131e, the rotation of the humidifying filter unit 13 can be stopped at the position where the accommodation section 131e enters the water tank 19. Therefore, when humidification is not performed, the humidifying filter 133 does not absorb water, and humidification can be reduced.

[0047] Next, the supply unit 140 will be described in detail with reference to Figures 3 and 4. Figure 4 is a schematic diagram of the supply unit 140.

[0048] The shape of the supply unit 140 includes a part of a substantially circular shape. In this embodiment, the supply unit 140 has a substantially D-shape when viewed from the front. With respect to the shape of the supply unit 140, the "circular shape" includes straight lines and curved lines. In other words, the circular shape may be a substantially perfect circle or a substantially elliptical shape as long as it includes straight lines and curved lines.

[0049] When edge EG3 on the curved side of supply unit 140 is located at the lowest position, edge EG3 is immersed in water W of water tub 19. In other words, when edge EG3 on the curved side of supply unit 140 is located at the lowest position, supply unit 140 pumps up water. When edge EG4 on the straight side of supply unit 140 is located at the highest position and is approximately parallel to the water surface of water tub 19, supply unit 140 supplies water to humidifying filter 133.

[0050] As shown in FIGS. 3 and 4, the supply unit 140 includes a storage unit 141, a pumping port 145, a discharge port 144, and a switching unit 142.

[0051] The storage section 141 stores the water pumped up from the pumping port 145. The storage section 141 has a cylindrical shape with one open end and the other closed end. The storage section 141 has a first side plate 241, a second side plate 242, a third side plate 243, a fourth side plate 244, and a flange portion 245. The first side plate 241 and the third side plate 243 have sides extending along the edge EG3 of the supply section 140. The second side plate 242 has a surface extending along the edge EG3 of the supply section 140. The fourth side plate 244 has a surface extending along the edge EG4 of the supply section 140. The flange portion 245 extends from the first side plate 241, the second side plate 242, the third side plate 243, and the fourth side plate 244. The flange portion 245 surrounds the opening 143.

[0052] The outlet 144 discharges water from the storage unit 141. As shown in FIG. 3, the outlet 144 faces the humidifying filter 133. Therefore, as shown in FIG. 3, when the edge EG4 on the straight side of the supply unit 140 is located at the uppermost position and is approximately parallel to the water surface of the water tank 19, the outlet 144 discharges water. The discharged water is absorbed by the humidifying filter 133. In other words, water is supplied to the humidifying filter 133. That is, the humidifying filter 133 not only absorbs the water in the water tank 19, but also absorbs the water discharged from the outlet 144. As a result, the humidifying filter 133 can be prevented from drying out excessively.

[0053] The pumping port 145 pumps up water from the water tank 19. Specifically, when the supply unit 140 is located inside the water tank 19, the pumping port 145 pumps up water from the water tank 19. As shown in FIG. 3, the pumping port 145 is disposed radially outward of the discharge port 144 with respect to the rotation axis AX. In other words, the pumping port 145 is disposed inside the holding unit 131 and near the outer edge of the holding unit 131. Therefore, when the pumping port 145 is located inside the water tank 19, the pumping port 145 is disposed near the bottom of the water tank 19. As a result, even if the water level in the water tank 19 drops, the pumping port 145 can pump up the water in the water tank 19.

[0054] The switching unit 142 switches the state of the storage unit 141 between a state in which the storage unit 141 and the discharge port 144 are in communication with each other and a state in which the storage unit 141 and the discharge port 144 are not in communication with each other. In a state in which the storage unit 141 and the discharge port 144 are in communication with each other, the water stored in the storage unit 141 is discharged from the discharge port 144. In a state in which the storage unit 141 and the discharge port 144 are not in communication with each other, the water stored in the storage unit 141 is not discharged from the discharge port 144. In other words, the switching unit 142 switches between a state in which the supply unit 140 supplies water to the humidifying filter 133 and a state in which the supply unit 140 does not supply water to the humidifying filter 133. For example, when the supply unit 140 is located at the uppermost position, the switching unit 142 can switch the supply unit 140 to a state in which the storage unit 141 and the discharge port 144 are in communication with each other. That is, water stored in storage unit 141 cannot be discharged from outlet 144 until supply unit 140 is located at the uppermost position. Therefore, water can be discharged from outlet 144 to humidifying filter 133 at a position suitable for supplying water to humidifying filter 133. As a result, excessive drying of humidifying filter 133 can be further suppressed.

[0055] The switching unit 142 has a rotating shaft 142A and a rotating plate 142B. The rotating shaft 242A rotatably supports the rotating plate 142B. An end of the rotating shaft 142A is fixed to the holding unit 131.

[0056] The rotating plate 142B rotates around the rotation axis of the rotating shaft 142A. Specifically, the rotating plate 142B rotates in a direction approaching the opening 143 and in a direction moving away from the opening 143.

[0057] When the rotating plate 142B rotates in a direction approaching the opening 143, the discharge opening 144 becomes narrower. When the rotating plate 142B rotates in a direction away from the opening 143, the discharge opening 144 becomes wider. When the rotating plate 142B rotates in a direction approaching the opening 143 and the rotating plate 142B and the opening 143 come into contact with each other, the opening 143 may be closed.

[0058] Next, the humidifying filter unit 13 of the first embodiment will be described in more detail with reference to Figs. 3 to 5. Fig. 5 is a diagram showing the humidifying filter unit 13 of the first embodiment. Fig. 5 shows the operation of the supply unit 140 up to the point where the pumped water is supplied to the humidifying filter 133. As shown in Fig. 5, the drive mechanism 21 of the first embodiment rotates the humidifying filter unit 13 in a first rotation direction R1. Also, the opening 143 of the storage unit 141 is open toward the first rotation direction R1.

[0059] 5 shows a first rotation state RA, a second rotation state RB, and a third rotation state RC of the humidifying filter unit 13. The first rotation state RA is a state in which the supply unit 140 is located inside the water tank 19 (see FIG. 3). In the first rotation state RA, water from the water tank 19 (see FIG. 3) flows into the storage unit 141 from the pumping port 145.

[0060] In the first rotation state RA, the switching unit 142 receives water pressure in the direction opposite to the first rotation direction R1. Therefore, the switching unit 142 switches the state of the storage unit 141 to a state in which the storage unit 141 and the outlet 144 are not in communication with each other. Also, in the first rotation state RA, the humidifying filter 133 is not located inside the water tub 19 (see FIG. 3).

[0061] The second rotation state RB indicates a state in which the holding unit 131 has rotated a predetermined angle in the first rotation direction R1 from the first rotation state RA. The second rotation state RB is a state in which the supply unit 140 is located outside the water tank 19. In the second rotation state RB, the storage unit 141 is located outside the water tank 19, and water is stored in the storage unit 141.

[0062] In the second rotation state RB, the switching unit 142 maintains a state in which the storage unit 141 and the discharge port 144 are not in communication with each other. The switching unit 142 comes into contact with the discharge port 144 due to the surface tension of the water adhering to the discharge port 144. Specifically, the rotating plate 142B comes into contact with the flange portion 245 due to the surface tension of the water adhering to the discharge port 144. Also, in the second rotation state RB, a part of the humidifying filter 133 is located inside the water tub 19 (see FIG. 3). That is, in the second rotation state RB, the humidifying filter 133 absorbs the water in the water tub 19.

[0063] The third rotation state RC indicates a state in which the holding portion 131 has rotated a predetermined angle in the first rotation direction R1 from the second rotation state RB. The third rotation state RC is a state in which the supply portion 140 is located outside the water tub 19, and the supply portion 140 supplies water to the humidifying filter 133. In the third rotation state RC, the switching portion 142 switches the state of the storage portion 141 to a state in which the storage portion 141 and the outlet 144 are in communication with each other.

[0064] Specifically, in the third rotation state RC, the water stored in storage portion 141 presses switching portion 142 in the first rotation direction R1. Then, switching portion 142 switches the state of supply portion 140 from a state in which storage portion 141 and outlet 144 are not in communication with each other to a state in which storage portion 141 and outlet 144 are in communication with each other. Therefore, the water stored in storage portion 141 is discharged from outlet 144. As a result, water is supplied to humidifying filter 133.

[0065] Furthermore, in the third rotation state RC, a part of the humidifying filter 133 is located inside the water tub 19 (see FIG. 3). That is, in the third rotation state RC, the humidifying filter 133 absorbs water from the water tub 19. Therefore, water is supplied to the humidifying filter 133 from the supply unit 140, and the humidifying filter 133 can absorb water from the water tub 19 as well. As a result, the humidifying filter 133 can be prevented from drying out.

[0066] [Embodiment 2] Next, a humidifying filter unit 13 according to a second embodiment will be described with reference to Fig. 1, Fig. 2, Fig. 6, and Fig. 7. The humidifying filter unit 13 according to the second embodiment differs from the humidifying filter unit 13 according to the first embodiment in that the humidifying filter unit 13 according to the second embodiment has a plurality of storage sections 141. Below, the differences between the second embodiment and the first embodiment will be described, and descriptions of parts that overlap with the first embodiment will be omitted.

[0067] Fig. 6 is an enlarged view of the humidifying filter unit 13 of the humidifier 100 of the embodiment 2. As shown in Fig. 6, the humidifying filter 133 is disposed around the rotation axis AX (Fig. 2).

[0068] 1 and 2, the humidifier 100 of the second embodiment includes a housing 1, an operation panel 3, a deodorizing filter 9, a dust collecting filter 11, a humidifying filter unit 13, a rotating shaft 15, a pair of shaft supports 17, a water tank 19, a drive mechanism 21, a blower 23, and a detection unit 30. The housing 1 accommodates the deodorizing filter 9, the dust collecting filter 11, the humidifying filter unit 13, the rotating shaft 15, the pair of shaft supports 17, the water tank 19, the drive mechanism 21, the blower 23, and the detection unit 30.

[0069] The drive mechanism 21 abuts against the peripheral edge of the humidifying filter unit 13 to rotate the humidifying filter unit 13. The drive mechanism 21 of the second embodiment rotates the humidifying filter unit 13 in a first rotation direction R1 and a second rotation direction R2. The second rotation direction R2 is the opposite direction to the first rotation direction R1.

[0070] The holder 131 of the humidifying filter unit 13 holds the humidifying filter 133 and the supply unit 140. The holder 131 of the second embodiment rotates in a first rotation direction R1 and a second rotation direction R2.

[0071] Supply unit 140 pumps up water from water tank 19, and supplies the water to humidifying filter 133. As shown in Figures 6 and 7, supply unit 140 includes a first storage unit 141A, a second storage unit 141B, a pumping port 145, a discharge port 144, and a switching unit 142.

[0072] First storage section 141A stores water pumped up from pumping port 145. First storage section 141A has a cylindrical shape with one open end and the other closed end. First storage section 141A has opening 143A that opens toward first rotation direction R1. When holding section 131 rotates in first rotation direction R1, first storage section 141A stores the water that flows in from pumping port 145.

[0073] Second storage section 141B stores the water pumped up from pumping port 145. Second storage section 141B has a cylindrical shape with one open end and the other closed end. Second storage section 141B has opening 143B that opens toward second rotation direction R2. When holding section 131 rotates in second rotation direction R2, second storage section 141B stores the water that flows in from pumping port 145.

[0074] That is, when holding portion 131 rotates in first rotation direction R1, water can be stored in first storage portion 141A, and when holding portion 131 rotates in second rotation direction R2, water can be stored in second storage portion 141B. Therefore, whether holding portion 131 rotates in first rotation direction R1 or second rotation direction R2, water pumped up from water tank 19 can be stored. Therefore, whether holding portion 131 rotates in first rotation direction R1 or second rotation direction R2, water can be supplied to humidifying filter 133. As a result, drying of humidifying filter 133 can be further suppressed.

[0075] Also, it is possible to prevent excess water from being supplied to humidifying filter 133. For example, when holding unit 131 rotates in first rotation direction R1, water is stored in first storage unit 141A, and water is not stored in second storage unit 141B. Because opening 143B of second storage unit 141B opens toward second rotation direction R2, when holding unit 131 rotates in first rotation direction R1 and supply unit 140 is located outside water tub 19, the water that has flowed into second storage unit 141B returns to water tub 19.

[0076] Furthermore, for example, when holding portion 131 rotates in second rotation direction R2, water is stored in second storage portion 141B, and water is not stored in first storage portion 141A. Since opening 143A of first storage portion 141A opens toward first rotation direction R1, when holding portion 131 rotates in second rotation direction R2 and supply portion 140 is positioned outside water tank 19, the water that has flowed into first storage portion 141A returns to water tank 19.

[0077] 6, opening 143A of first storage section 141A and opening 143B of second storage section 141B of embodiment 2 face each other. Therefore, when holding section 131 stops at a position where detection section 30 detects detected member 301, water W is stored in first storage section 141A and second storage section 141B, respectively. In other words, when drive mechanism 21 resumes rotation of holding section 131, water can be immediately supplied to humidifying filter 133 regardless of whether holding section 131 rotates in first rotation direction R1 or second rotation direction R2. As a result, humidifying filter 133 can be easily moistened.

[0078] Outlet 144 discharges the water in first storage portion 141A or the water in second storage portion 141B. Outlet 144 faces humidification filter 133. The water discharged from outlet 144 is absorbed by humidification filter 133. Outlet 144 is disposed between first storage portion 141A and second storage portion 141B.

[0079] The pumping port 145 pumps up water from the water tank 19. The pumped up water flows into the first storage section 141A and the second storage section 141B. Specifically, the water flows from the water tank 19 into the first storage section 141A and the second storage section 141B through the pumping port 145. The pumping port 145 is disposed between the first storage section 141A and the second storage section 141B.

[0080] 6, detected member 301 is disposed at the position of pumping port 145. Driving mechanism 21 stops driving at a position where detection unit 30 detects detected member 301. That is, driving mechanism 21 stops driving at a position where pumping port 145 faces the bottom of water tank 19, and pumping port 145 is located below the water level of water tank 19. Therefore, water can easily flow from pumping port 145 into first storage section 141A and second storage section 141B. The flow of water into first storage section 141A and second storage section 141B continues until the water level becomes the same as the water level of water tank 19.

[0081] The switching unit 142 switches between the state of the first storage unit 141A and the state of the second storage unit 141B in response to the rotation of the holding unit 131. Specifically, the switching unit 142 switches between the state of the first storage unit 141A and the state of the second storage unit 141B between a first state and a second state. The first state indicates a state in which the opening 143A of the first storage unit 141A and the discharge port 144 are in communication with each other, and the opening 143B of the second storage unit 141B and the discharge port 144 are not in communication with each other. The second state indicates a state in which the opening 143B of the second storage unit 141B and the discharge port 144 are in communication with each other, and the opening 143A of the first storage unit 141A and the discharge port 144 are not in communication with each other.

[0082] Therefore, in response to the rotation of holding portion 131, switching portion 142 switches between the first state and the second state, and water can be transported to a position where it is supplied to humidifying filter 133. Furthermore, the transported water can be supplied to humidifying filter 133. As a result, a sufficient amount of water can be supplied to humidifying filter 133 while suppressing a decrease in the amount of water supplied to humidifying filter 133. In addition, water discharged from supply portion 140 does not flow into the opposing storage portion 141, and the water in storage portion 141 can be supplied to humidifying filter 133.

[0083] For example, when rotating in first rotation direction R1, switching unit 142 switches the state of first storage unit 141A and the state of second storage unit 141B to the second state, thereby preventing the water stored in first storage unit 141A from leaking and reducing the amount of water supplied to humidifying filter 133. Furthermore, for example, switching unit 142 switches the state of first storage unit 141A and the state of second storage unit 141B to the first state, thereby allowing the water stored in first storage unit 141A to be supplied to humidifying filter 133.

[0084] For example, when rotating in second rotation direction R2, switching unit 142 switches the state of first storage unit 141A and the state of second storage unit 141B to the first state, which can prevent the water stored in second storage unit 141B from leaking and reducing the amount of water supplied to humidifying filter 133. Furthermore, for example, switching unit 142 switches the state of first storage unit 141A and the state of second storage unit 141B to the second state, which can supply the water stored in second storage unit 141B to humidifying filter 133.

[0085] 6, switching unit 142 is disposed at the position of pumping port 145. Specifically, switching unit 142 is disposed between first storage unit 141A and second storage unit 141B.

[0086] Next, the humidifying filter unit 13 of the second embodiment will be described in more detail with reference to Fig. 6 and Fig. 7. Fig. 7 is a diagram showing the humidifying filter unit 13 of the second embodiment. Fig. 7 shows the operation of the supply unit 140 up to the point where the pumped water is supplied to the humidifying filter 133. In Fig. 7, the drive mechanism 21 rotates the humidifying filter unit 13 in a first rotation direction R1. The drive mechanism 21 of the second embodiment is capable of rotating the holding portion 131 in the first rotation direction R1 and the second rotation direction R2, but the case of rotation in the first rotation direction R1 will be described as an example.

[0087] 7 shows a first rotation state RA, a second rotation state RB, and a third rotation state RC of the humidifying filter unit 13. The first rotation state RA is a state in which the supply unit 140 is located inside the water tank 19 (see FIG. 6). The water pumped up from the pumping port 145 enters the first storage unit 141A and the second storage unit 141B. In the first rotation state RA, the switching unit 142 receives water pressure in a direction opposite to the first rotation direction R1. Therefore, the switching unit 142 switches the state of the first storage unit 141A and the state of the second storage unit 141B to the second state. That is, the switching unit 142 switches to a state in which the opening 143B of the second storage unit 141B communicates with the outlet 144 and the opening 143A of the first storage unit 141A does not communicate with the outlet 144. In the first rotation state RA, the humidifying filter 133 is not located inside the water tub 19 (see FIG. 6).

[0088] The second rotation state RB indicates a state in which the holding section 131 has rotated from the first rotation state RA by a predetermined angle in the first rotation direction R1. The second rotation state RB is a state in which the first storage section 141A and the second storage section 141B are located outside the water tub 19. Water is stored in the first storage section 141A. Water is not stored in the second storage section 141B. Since the opening 143B of the second storage section 141B opens toward the second rotation direction R2, when the second rotation state RB is reached, the water in the second storage section 141B returns to the water tub 19. In the second rotation state RB, the switching section 142 maintains the second state. Also, in the second rotation state RB, a part of the humidifying filter 133 is located inside the water tub 19 (see FIG. 3). That is, in the second rotation state RB, the humidifying filter 133 absorbs water from the water tub 19.

[0089] The third rotation state RC indicates a state in which the holding portion 131 has rotated from the second rotation state RB by a predetermined angle in the first rotation direction R1. The third rotation state RC is a state in which the supply portion 140 is located outside the water tub 19, and the supply portion 140 supplies water to the humidifying filter 133. In the third rotation state RC, the switching portion 142 switches the state of the first storage portion 141A and the state of the second storage portion 141B to the first state. That is, the switching portion 142 switches to a state in which the opening 143A of the first storage portion 141A and the discharge port 144 are in communication with each other, and the opening 143B of the second storage portion 141B and the discharge port 144 are not in communication with each other.

[0090] Specifically, in the third rotation state RC, the water stored in first storage portion 141A presses switching portion 142 in first rotation direction R1. Then, switching portion 142 switches between the state of first storage portion 141A and the state of second storage portion 141B to the first state. Therefore, the water stored in first storage portion 141A is discharged from outlet 144. As a result, water is supplied to humidifying filter 133.

[0091] Furthermore, in the third rotation state RC, a part of the humidifying filter 133 is located inside the water tub 19 (see FIG. 3). That is, in the third rotation state RC, the humidifying filter 133 absorbs water from the water tub 19. Therefore, water is supplied to the humidifying filter 133 from the supply unit 140, and the humidifying filter 133 is able to absorb water from the water tub 19. As a result, it is possible to prevent the humidifying filter 133 from drying out.

[0092] When the holding portion 131 rotates in the second rotation direction R2, the movement of the switching portion 142 to switch between the first state and the second state is reversed.

[0093] [Embodiment 3] Next, a humidifying filter unit 13 according to a third embodiment will be described with reference to Fig. 1, Fig. 2, and Fig. 8. The humidifying filter unit 13 according to the third embodiment differs from the first and second embodiments in the shape of the supply unit 140. Below, the third embodiment will be described with respect to differences from the first and second embodiments, and descriptions of parts that overlap with the first and second embodiments will be omitted.

[0094] FIG. 8 shows the humidifying filter unit 13 according to the third embodiment. In FIG. 8, the storage section 131e is omitted in order to make the invention easier to see. As shown in FIG. 8, the frame 131a has a circular shape. The frame 131a covers the edge EG1 of the humidifying filter 133 and is disposed outside the humidifying filter 133. The frame 131a also covers the edge EG3 of the supply section 140 and is disposed outside the edge EG3 of the supply section 140. In other words, the frame 131a is disposed outside the first holding portion and the second holding portion.

[0095] The supply unit 140 of the third embodiment has a sector shape in accordance with the shape of the storage unit 131e (not shown). The humidification filter 133 has a part cut out in a sector shape.

[0096] Supply unit 140 supplies water to humidifying filter 133. When edge EG3 on the curved side of supply unit 140 is located at the lowest position, edge EG3 is immersed in water W of water tub 19. In other words, when edge EG3 on the curved side of supply unit 140 is located at the lowest position, supply unit 140 pumps up water. When edge EG4 on the straight side of supply unit 140 is located at the highest position and is approximately parallel to the water surface of water tub 19, supply unit 140 supplies water to humidifying filter 133.

[0097] As shown in FIG. 8, the supply section 140 includes a storage section 141 .

[0098] The water is stored in the storage section 141. The storage section 141 has an opening 143.

[0099] The opening 143 functions as a discharge port and a pumping port.

[0100] The opening 143 as an outlet discharges water from the storage unit 141. As shown in FIG. 8, the opening 143 faces the humidifying filter 133. Therefore, as shown in FIG. 8, when the edge EG4 on the straight side of the supply unit 140 is located at the uppermost position and is approximately parallel to the water surface of the water tank 19, the opening 143 as an outlet discharges water. The discharged water is absorbed by the humidifying filter 133. In other words, water is supplied to the humidifying filter 133. That is, the humidifying filter 133 not only absorbs the water in the water tank 19, but also absorbs the water discharged from the opening 143 as an outlet. As a result, the humidifying filter 133 can be prevented from drying out excessively.

[0101] Opening 143 as a pumping port pumps up water from water tank 19. Specifically, when supply unit 140 is located inside water tank 19, opening 143 as a pumping port pumps up water from water tank 19. Specifically, when opening 143 as a pumping port is located inside water tank 19, humidifying filter unit 13 rotates in first rotation direction R1, so that water in water tank 19 can be pumped up from opening 143 as a pumping port.

[0102] [Variation 1] Next, a first modified example of the humidifying filter unit 13 of the third embodiment will be described with reference to Fig. 1, Fig. 2, and Fig. 9. The humidifying filter unit 13 according to the first modified example of the third embodiment differs from that of the third embodiment in the shape of the supply section 140. Below, the first modified example of the third embodiment will be described with respect to the points different from the third embodiment, and a description of the points overlapping with the third embodiment will be omitted.

[0103] Fig. 9 shows a humidifying filter unit 13 according to a first modified example of the third embodiment. In Fig. 9, the container 131e is omitted in order to make the invention easier to see.

[0104] Supply unit 140 of modification 1 has a non-circular shape to match the shape of storage unit 131e (not shown). In modification 1, supply unit 140 has a substantially D-shape in a front view. Specifically, with regard to the shape of supply unit 140, the "non-circular shape" includes straight lines and curved lines.

[0105] As shown in FIG. 9, the supply unit 140 includes a storage unit 141. The storage unit 141 stores water. The storage unit 141 has a shape with one side open and the other side closed. The storage unit 141 has an opening 143. The opening 143 is disposed on an edge EG4 on the straight side of the supply unit 140. Specifically, the opening 143 is disposed on an imaginary line connecting the rotation axis AX and the detected member 301. Therefore, when the edge EG4 on the straight side of the supply unit 140 is immersed in the water of the water tank 19, water enters through the opening 143 and is stored in the storage unit 141. The opening 143 functions as a discharge port and a pumping port.

[0106] [Variation 2] Next, a first modified example of the humidifying filter unit 13 of the third embodiment will be described with reference to Fig. 1, Fig. 2, and Fig. 10. The humidifying filter unit 13 according to a second modified example of the third embodiment differs from that of the third embodiment in the shape of the supply section 140. Below, the second modified example of the third embodiment will be described with respect to the points different from the third embodiment, and a description of the points that overlap with the third embodiment will be omitted.

[0107] Fig. 10 shows a humidifying filter unit 13 according to Modification 2 of Embodiment 3. In Fig. 10, the container 131e is omitted in order to make the invention easier to see.

[0108] Supply unit 140 of modification 2 has a non-circular shape to match the shape of storage unit 131e (not shown). In modification 1, supply unit 140 has a substantially D-shape in front view. Specifically, with regard to the shape of supply unit 140, the "non-circular shape" includes straight lines and curved lines.

[0109] As shown in FIG. 10, the supply unit 140 includes a storage unit 141. The storage unit 141 stores water. The storage unit 141 has a shape with one side open and the other side closed. The storage unit 141 has an opening 143. The opening 143 is arranged on an edge EG4 on the straight side of the supply unit 140. In the second modification, when rotating in the first rotation direction R1, water enters the water tank 19 from the opening 143. Therefore, water enters the storage unit 141 from the opening 143 in accordance with the rotation in the first rotation direction R1. Water enters from the opening 143 and is stored in the storage unit 141. The opening 143 functions as a discharge port and a pumping port.

[0110] The supply unit 140 of the third embodiment, the first modification of the third embodiment, and the second modification of the third embodiment may further include the switch unit 142 shown in the first and second embodiments.

[0111] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments, and can be implemented in various aspects without departing from the gist of the present invention. In addition, various inventions can be formed by appropriately combining multiple components disclosed in each of the above embodiments. For example, some components may be deleted from all components shown in the embodiments. Furthermore, components across different embodiments may be appropriately combined. The drawings are mainly shown in a schematic manner for ease of understanding, and the thickness, length, number, spacing, etc. of each component shown in the drawings are different from the actual ones due to the convenience of drawing. In addition, the speed, material, shape, dimensions, etc. of each component shown in the above embodiments are only examples and are not particularly limited, and various changes are possible within a range that does not substantially deviate from the configuration of the present invention.

[0112] (1) In the first embodiment, the holding portion 131 rotates in the first rotation direction D1, but this is not limited thereto. For example, the holding portion 131 may rotate in the second rotation direction D2. When the holding portion 131 rotates in the second rotation direction D2, the opening 143 of the storage portion 141 opens toward the second rotation direction D2.

[0113] (2) The humidifying filter 133 in the first embodiment and the humidifying filter 133 in the second embodiment are substantially D-shaped, but are not limited to this. The humidifying filter 133 may be, for example, polygonal. For example, the humidifying filter 133 may be, for example, substantially triangular. Furthermore, for example, the humidifying filter 133 may be, for example, substantially rectangular.

[0114] (3) In the first and second embodiments, it has been described that the surface tension of the water adhering to the outlet 144 causes the rotating plate 142B to abut against the flange portion 245, but this is not limited thereto. For example, the rotating shaft 142A may have a driving mechanism 21, and a detector additionally provided on a side wall near the periphery of the humidifying filter unit 13 may detect a detected member 301 attached to the humidifying filter unit 13, and the rotating shaft 142A may repeatedly switch between a state in which the storage unit 141 and the outlet 144 do not communicate with each other and a state in which the storage unit 141 and the outlet 144 communicate with each other.

[0115] Specifically, the rotating plate 142B is rotated by a motor of the drive mechanism 21. The drive mechanism 21 rotates the rotating plate 142B when the detection unit 30 detects the detected member 301. That is, when it detects that the opening 143 has come to the upper position, the rotating plate 142B is rotated to supply water to the humidifying filter 133. Therefore, water can be efficiently supplied to the humidifying filter 133.

[0116] (4) Although an example has been shown in which the pumping port 145 is positioned radially outward of the discharge port 144 relative to the rotation axis AX, the pumping port 145 does not necessarily have to be formed outside the discharge port 144, and the pumping port 145 may serve as both the pumping port 145 and the discharge port 144.

[0117] (5) In the second embodiment, an example in which opening 143 of first storage section 141A and opening 143 of second storage section 141B face each other has been described, but the present invention is not limited thereto. For example, opening 143 of first storage section 141A and opening 143 of second storage section 141B do not have to face each other. In this case, supply section 140 further includes switching section 142 that switches the state of first storage section 141A and switching section 142 that switches the state of second storage section 141B. Switching section 142 that switches the state of first storage section 141A switches the state of first storage section 141A between a state in which first storage section 141A and discharge port 144 communicate with each other and a state in which first storage section 141A and discharge port 144 do not communicate with each other. In addition, switching unit 142, which switches the state of second storage unit 141B, switches the state of second storage unit 141B between a state in which second storage unit 141B and discharge outlet 144 are connected and a state in which second storage unit 141B and discharge outlet 144 are not connected.
