  The problem in the above conventional example is that the humidifying ability is low.

  That is, in the conventional thing, the water of the water tank was pumped up from the outer peripheral part end surface of the disk-shaped humidification filter, and was supplied. The water supplied to the outer peripheral end face of this humidifying filter flows down to the lower part of the humidifying filter while passing through the humidifying filter, so that the entire humidifying filter contains water, and the humidifying filter containing this water is blown by a blowing means. The air was humidified.

  Therefore, in order to improve the humidifying capacity, if the air volume by the air blowing means is increased and the air volume passing through the humidifying filter containing water is increased, the water supplied to the outer peripheral end face of the humidifying filter is supplied to the humidifying filter by the air blowing means. The blown air flows into the humidifying filter surface on the leeward side without flowing down in the humidifying filter. In other words, the water that was going to flow down from the outer peripheral end face of the humidifying filter to the central part while passing through the humidifying filter flows horizontally into the leeward side of the humidifying filter by the air flow, and as a result, the water is entirely put into the humidifying filter. It cannot be included, that is, water can be included only in a small area of the humidifying filter, which makes it difficult to increase the air volume and improve the humidifying ability.

  Therefore, the present invention aims to improve the humidifying ability.

  In order to achieve this object, the present invention comprises a main body case having an intake port and an exhaust port, and humidifying means provided in the main body case. The humidifying means includes a water tank for storing water, and a water tank in the water tank. A disc-shaped humidifying filter part whose lower end is immersed in water, a water supply part for pumping and supplying water from the water tank to the humidifying filter part, and covering the humidifying filter part, and the water supply part on the outer peripheral part thereof An air passage of the humidifying means is formed by a fixed filter frame portion and a rotating means that rotates around a shaft portion at the center of the filter frame portion, and blows air from the intake port to the exhaust port. Provided on the leeward side, the water supply portion is located at the peripheral edge of the filter frame portion on the windward side of the air path, has a substantially box shape, and includes a first opening and a second opening, and the first opening Is the rotation of the filter frame. The second opening is provided in the center direction of the filter frame portion, and includes a communication passage portion that communicates the second opening portion and the filter frame portion. The passage portion extends from the second opening portion to a center portion of the filter frame portion, an upstream side wall portion provided on the upstream side of the rotation direction of the filter frame portion of the second opening portion, and the second opening portion. It is formed from a downstream side wall provided on the downstream side in the rotation direction of the filter frame part of the opening, and an upwind side wall that closes the wind path windward side between the upstream side wall and the downstream side wall, This achieves the initial objective.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, and humidifying means provided in the main body case. The humidifying means has a water tank for storing water, and a lower end of the water in the water tank. A disk-shaped humidifying filter part to be immersed, a water supply part for pumping and supplying water from the water tank to the humidifying filter part, and a filter frame covering the humidifying filter part and fixing the water supplying part to the outer peripheral part thereof And a rotating means for rotating about the central shaft portion of the filter frame, and a blowing means for blowing air from the intake port to the exhaust port is provided on the downwind side of the humidifying means.

Is.

  That is, the water supply unit fixed to the filter frame part rotates to pump water from the first opening and from the second opening to the humidification filter part through the communication path part. Water supply. The communication passage portion is surrounded by the upstream side wall portion, the downstream side wall portion, and the windward side wall portion, and communicates the second opening portion and the filter frame portion, so that the water supply portion is connected to the first opening portion. Until the water in the water tank is pumped and rotated from 10 o'clock to 12 o'clock (uppermost part) of the watch, the water mainly flows through the humidifying filter part along the upstream side wall, and from 12 o'clock (uppermost part) of the watch. Until it rotates at approximately 2 pm, water mainly flows through the humidifying filter part while traveling along the downstream side wall part. Here, since the windward side wall portion can suppress the influence of the blowing air, the water flows from the peripheral portion of the humidifying filter portion to the central portion, and the water is included in the wide area on the windward side of the humidifying filter portion. It is something that can be done.

  Based on these results, the humidifying ability can be improved.

In the center direction of the portion 10, that is, on the inner peripheral surface, it is a substantially square shape located on the downstream side in the rotation direction of the filter frame portion 10.

  As shown in FIGS. 3 and 6, the filter frame portion 10 is formed of a disk-shaped upstream filter frame 17 and a disk-shaped downstream filter frame 18. The upstream filter frame 17 is provided with a cylindrical upstream shaft portion 19 that extends outward at the center and is provided with a fixing portion 20 for the water supply portion 9 at the periphery. The downstream filter frame 18 is provided with a cylindrical downstream shaft portion 21 that extends outward at the center, and a cylindrical cylinder that covers the outer peripheral portion of the upstream filter frame 17 at the periphery.

  The humidifying means 6 has a water supply part 9 mounted on a fixed part 20 provided on the outer periphery of the upstream filter frame 17, and a humidifying filter part 8 is inserted between the upstream filter frame 17 and the downstream filter frame 18, The side filter frame 17 and the downstream filter frame 18 are fitted together, and the upstream shaft portion 19 of the upstream filter frame 17 and the downstream shaft portion 21 of the downstream filter frame 18 are rotated on the bearing portion 25 of the water tank 7. The filter frame 10, the water supply unit 9, and the humidifying filter unit 8 are rotated by the rotating means 12 via the gear unit 23 of the downstream filter frame 18.

  The air cleaning and humidification operation in such a configuration will be described.

  Water is supplied from the water tank 14 to the water tank 7 so that the water level is always constant. The water supply unit 9 and the humidification filter unit 8 of the humidifying unit 6 are always immersed in this water. Here, by rotating the filter frame portion 10 by the rotating means 12, the water supply portion 9 and the humidification filter portion 8 that have drawn water rotate, and the water pumped up by the water supply portion 9 reaches the humidification filter portion 8 near the top. Supply water. That is, the humidifying filter unit 8 is always kept in a state of holding water by continuously rotating the filter frame unit 10 by the rotating means 12.

  Here, by moving the air blowing means 13, air is sucked into the main body case 4 from the air inlet 2, and this air is a humidifying filter portion that holds the air purifying filter 5 a provided in the main body case 4 and water. 8 and becomes humidified clean air, and is exhausted from the exhaust port 3 into the room.

  As shown in FIGS. 5 to 7, the present embodiment is characterized in that water is supplied from the second opening 16 of the water supply unit 9 to the humidifying filter unit 8. The second opening 16 of the water supply unit 9 attached to the fixed portion 20 of the upstream filter frame 17 is provided with a communication passage portion 26 that communicates with the filter frame portion 10, and the communication passage portion 26 has an upstream side wall portion. 27, the downstream side wall portion 28, and the upwind side wall portion 29 are substantially U-shaped in cross section, and the second of the water supply portion 9 attached to the fixing portion 20 of the upstream filter frame 17 The opening 16 extends to the upstream shaft 19 that is the center of the filter frame 10. The upstream side wall 27 is located upstream of the second opening 16 in the rotation direction of the filter frame 10, and the downstream side wall 28 is downstream of the second opening 16 in the rotation direction of the filter frame 10. The upwind side wall 29 is located on the windward side of the wind path between the upstream side wall 27 and the downstream side wall 28, connects the upstream side wall 27 and the downstream side wall 28, and The air passage between the downstream side wall portion 28 is blocked.

  That is, the water supply unit 9 fixed to the filter frame unit 10 rotates to draw water from the water tank 7 from the first opening 15 and humidifies the second opening 16 via the communication path unit 26. Water in the water tank 7 is supplied to the filter unit 8. Since this communication path part 26 is surrounded by the upstream side wall part 27, the downstream side wall part 28, and the windward side wall part 29, the 2nd opening part 16 and the filter frame part 10 are connected, Therefore A water supply part is Until the water in the water tank is pumped from the first opening and rotated from, for example, 10 o'clock to 12 o'clock (the uppermost part), the water mainly flows through the upstream side wall 27 and flows into the humidifying filter 8. From 12:00 (uppermost part) until approximately 2:00 pm, water mainly flows through the humidified filter part 8 along the downstream side wall part 28. Here, since the windward side wall 29 can suppress the influence of the air blowing by the air blowing means 13, the water flows from the peripheral edge to the center of the humidifying filter 8, and the water is spread over a wide area on the wind path windward side of the humidifying filter 8. Can be included.

  Based on these results, the humidifying ability can be improved.

  Further, the upstream side wall portion 27 of the communication passage portion 26 has a substantially vertically long plate shape, and the axial dimension of the filter frame portion 10 gradually decreases from the peripheral portion of the filter frame portion 10 to the center portion of the filter frame portion 10. In this configuration, the distance from the humidifying filter unit 8 is increased. Specifically, the upstream side wall portion 27 of the communication passage portion 26 has a substantially vertically long flat plate shape, and the air path leeward side end surface, that is, the end surface on the humidifying filter portion 8 side, extends from the peripheral portion toward the center portion of the filter frame portion 10. Accordingly, it inclines so as to approach the wind path windward side, that is, the windward side wall part side.

  That is, the water supply unit 9 is attached to the fixing unit 20 of the upstream filter frame 17, and the humidification filter unit 8 is inserted between the upstream filter frame 17 and the downstream filter frame 18. When the filter frame 18 is fitted together, the wind path leeward side end surface of the upstream side wall portion 27 of the communication passage portion 26 contacts the humidifying filter portion 8. Here, the humidification filter unit 8 has a three-layer structure in which a second layer is sandwiched between two disc-shaped first layers, and the second layer is perpendicular to the first layer. Since it is formed of a plurality of yarns and has elasticity, the surface of the humidifying filter portion 8 on the windward side is inclined along the wind path leeward side end surface of the upstream side wall portion 27 of the communication passage portion 26. Thereby, while the water supply part 9 draws the water of the water tank 7 from the 1st opening part 15, and rotates from 10:00 to 12:00 (uppermost part) of a timepiece, the upstream side wall part 27 of the communicating path part 26 is made. Although the water that travels through the water flows along the windward leeward side end surface of the upstream side wall portion 27, the water that mainly feeds the peripheral edge portion of the humidifying filter portion 8, and the water that travels near the windward side wall portion 29 of the upstream side wall portion 27 Primarily, water is supplied to the central portion of the humidifying filter portion 8, and as a result, water can be supplied almost evenly over a wide area of the humidifying filter portion 8.

  Further, the downstream side wall portion 28 of the communication passage portion 26 has a substantially vertically long plate shape, and the axial dimension of the filter frame portion 10 gradually decreases from the peripheral portion of the filter frame portion 10 to the center portion of the filter frame portion 10. In this configuration, the distance from the humidifying filter 8 is increased. Specifically, the downstream side wall portion 28 of the communication passage portion 26 has a substantially vertically long flat plate shape, and the end surface on the air path leeward side, that is, the end surface on the humidifying filter portion 8 side, extends from the peripheral portion to the center portion of the filter frame portion 10. Accordingly, it inclines so as to approach the wind path windward side, that is, the windward side wall 29 side.

  That is, the water supply unit 9 is attached to the fixing unit 20 of the upstream filter frame 17, and the humidification filter unit 8 is inserted between the upstream filter frame 17 and the downstream filter frame 18. When the filter frame 18 is fitted together, the wind path leeward side end surface of the downstream side wall portion 28 of the communication passage portion 26 contacts the humidifying filter portion 8. Here, the humidification filter unit 8 has a three-layer structure in which a second layer is sandwiched between two disc-shaped first layers, and the second layer is perpendicular to the first layer. Since it is formed of a plurality of yarns and has elasticity, the surface on the windward side of the humidifying filter portion 8 is inclined along the wind path leeward side end surface of the downstream side wall portion 28 of the communication passage portion 26. As a result, the water supply unit 9 pumps up the water in the water tank 7 from the first opening 15, and travels through the downstream side wall 28 of the communication passage unit 26 while rotating approximately 2 o'clock from 12 o'clock (uppermost part) of the watch. However, the water that travels near the windward leeward end surface of the downstream side wall 28 is mainly supplied to the peripheral edge of the humidifying filter 8 and the water that travels near the windward side wall 29 of the downstream side wall 28 is Mainly, water is supplied to the central portion of the humidifying filter portion 8, and as a result, water can be supplied almost evenly over a wide area of the humidifying filter portion 8.

  Further, the upstream side wall portion 27 of the communication passage portion 26 increases in distance from the downstream side wall portion 28 as it goes from the wind path windward side to the wind path leeward side. Specifically, the water supply unit 9 draws water from the water tank 7 from the first opening 15 and rotates from 9 o'clock to 12 o'clock (the uppermost part) of the timepiece at the 9 o'clock position, for example. The end surface of the upstream side wall portion 27 of the portion 26 on the downwind side, that is, the end surface on the humidifying filter portion 8 side is lowered, and the upstream side wall portion 27 is inclined downward.

  That is, the water supply unit 9 pumps the water in the water tank 7 from the first opening 15 and rotates along the upstream side wall 27 of the communication passage 26 while rotating from approximately 10 o'clock to 12 o'clock (the uppermost part). Since the flowing water easily flows to the humidifying filter section 8 side, the amount of water flowing into the water tank 7 without flowing into the humidifying filter section 8 can be reduced.

  Further, the downstream side wall portion 28 of the communication passage portion 26 increases in distance from the upstream side wall portion 27 as it goes from the wind path windward side to the wind path leeward side. Specifically, the water supply section 9 draws water from the first opening 15 and circulates the water at the 3 o'clock position while rotating approximately 6 o'clock from 12 o'clock (the uppermost part) of the clock, for example. 26, the end surface of the downstream side wall portion 28 on the downwind side, that is, the end surface on the humidifying filter portion 8 side is lowered, and the downstream side wall portion 28 is inclined downward.

  That is, the water supply unit 9 pumps the water in the water tank from the first opening 15 and rotates along the downstream side wall portion 28 of the communication passage portion 26 while rotating approximately 2 o'clock from 12 o'clock (uppermost portion) of the watch, for example. Since the flowing water is likely to flow toward the humidifying filter unit 8, the amount of water that flows into the water tank 7 without flowing into the humidifying filter unit 8 can be reduced.

  Further, water flow direction changing means is provided in the communication passage portion 26. The water flow direction changing means in the communication passage portion 26 is a protrusion 30 that protrudes from the windward side wall portion 29 into the communication passage portion 26. Specifically, the water flow direction changing means is located in the intermediate portion between the second opening 16 of the water supply portion 9 and the upstream shaft portion 19 of the upstream filter frame 17 in the communication passage portion 26. The protrusion 30 protrudes from the windward side wall 29 into the communication path 26 so as to be connected to the upstream side wall 27 and the downstream side wall 28.

  That is, the water that travels near the windward side wall 29 of the upstream side wall 27 or the downstream side wall 28 flows from the second opening 16 of the water supply unit 9 to the upstream shaft 19 of the upstream filter frame 17. Since the water flow direction changes in the direction of the humidifying filter unit 8 when it hits the protrusion 30 which is the water flow direction changing means, the amount of water flowing into the water tank 7 without flowing into the humidifying filter unit 8 can be reduced.

  In addition, the opening area of the second opening 16 of the water supply unit 9 is smaller than the opening area of the first opening 15.

  That is, since the opening area of the second opening 16 of the water supply unit 9 is smaller than the opening area of the first opening 15, all the water in the water supply unit 9 is discharged from the second opening 16 of the water supply unit 9. Since time until it flows down becomes long, water supply time becomes long and the water absorption rate of the humidification filter part 8 can be improved.

  Further, the second opening 16 of the water supply unit 9 is configured to communicate with the downstream side wall 28 of the communication path 26. Specifically, the water supply unit 9 has a substantially box shape with one surface opened, and includes a second opening 16 having a substantially square shape on one side of the first opening 15 of the water supply unit 9. The first opening 15 of the water supply unit 9 is positioned on the downstream side in the rotation direction of the filter frame unit 10, and the second opening 16 of the water supply unit 9 is positioned in the center direction of the filter frame unit 10. The water supply unit 9 is attached to the fixing unit 20 of the upstream filter frame 17. The fixing portion 20 includes a claw portion 31 extending inward of the filter frame portion 10 from the upstream filter frame 17 and a water supply portion 9 so as to sandwich the surface of the water supply portion 9 facing the first opening 15. A substantially flat plate-shaped first fixed wall extending from the peripheral end portion of the upstream side wall portion 27 of the communication passage portion 26 to the upstream side in the rotation direction of the filter frame portion 10 so as to cover the surface having the second opening portion 16. Extended from the peripheral end of the downstream side wall 28 of the communication passage 26 to the outer periphery in the radial direction of the filter frame 10 so as to cover the area of the portion 32 and the first opening 15 of the water supply unit 9. The second fixed wall portion 33 is formed in a substantially flat plate shape.

  That is, while the filter frame portion 10 rotates, for example, from 5 o'clock to 7 o'clock, the water in the water tank 7 is pumped from the first opening 15 that is the water supply portion 9, and then the filter frame portion 10 is The water flows from the second opening 16 of the water supply section 9 to the upstream side wall section 27 of the communication passage section 26, and the filter frame section 10 While rotating from 12:00 (topmost part) of the timepiece to approximately 2:00 pm, water flows from the second opening 16 of the water supply unit 9 to the downstream side wall 28 of the communication passage unit 26. Here, the water supply unit 9 The water inside is the three surfaces of the second fixed wall 33 and the water supply unit 9, that is, the surface having the second opening 16 of the water supply unit 9, the surface of the water supply unit 9 on the windward side of the second wind path, and Water accumulates in a space surrounded by the surface of the water supply unit 9 on the downwind side of the wind path, and the second opening 1 is formed at the bottom of this space. But it is intended to position. As a result, the water in the water supply part 9 can flow out from the second opening 16 to the downstream side wall part 28 of the communication path part 26 without remaining in the water supply part 9.

  A plurality of water supply portions 9 are provided, and each communication passage portion 26 extending from the water supply portion 9 has a configuration in which the communication passage portions 26 communicate with each other at the center of the filter frame portion 10. Specifically, the end portion of the upstream side wall portion 27 of the adjacent communication passage portion 26 on the center portion side of the filter frame portion 10 and the central portion side of the filter frame portion 10 of the downstream side wall portion 28 of the communication passage portion 26 are arranged. The end is connected.

  That is, the water that flows from the second opening 16 of the water supply unit 9 to the communication passage portion 26 and does not flow to the humidifying filter portion 8 but to the central portion of the filter frame portion 10 of the communication passage portion 26 passes through other communication passages. The water flows into the portion 26, and water can flow into the humidifying filter portion 8 from the communication passage portion 26. As a result, since water can be supplied to a wider area of the humidifying filter portion 8, water can be supplied almost evenly to the wide area of the humidifying filter portion 8.

  Further, a water dispersion means is provided in the communication passage portion 26 at the center portion of the filter frame portion 10. The water dispersion means is a protrusion 34 that protrudes into the communication path portion 26. Specifically, from the upstream filter frame 17 that is the filter frame portion 10 to the central portion of the upstream filter frame 17 in the communication passage portion 26, that is, in the communication passage portion 26 in which each communication passage portion 26 communicates. A plurality of projections 34 having a substantially flat plate shape.

  That is, the water that flows from the second opening 16 of the water supply unit 9 to the communication passage portion 26 and does not flow to the humidifying filter portion 8 but to the central portion of the filter frame portion 10 of the communication passage portion 26 is water-dispersing means. Water hits a plurality of substantially flat projections 34, and the water is dispersed, so that not only the other plurality of communication passage portions 26, that is, the communication passage portion 26 at, for example, 6 o'clock position of the timepiece, but also from about 4 o'clock of the timepiece. It becomes easy to flow into the communication passage portion 26 at 5 o'clock and approximately 7 o'clock to 8 o'clock of the timepiece. As a result, since water flows into the humidifying filter portion 8 from the plurality of communication passage portions 26, water can be supplied to a wider area of the humidifying filter portion 8, and water can be supplied almost evenly to the wide area of the humidifying filter portion 8.

  Further, the distance between the upstream side wall portion 27 and the downstream side wall portion 28 of the communication passage portion 26 is the largest in the central portion of the filter frame portion 10. Specifically, the interval between the upstream side wall portion 27 and the downstream side wall portion 28 of the communication passage portion 26 is the same size from the periphery of the filter frame portion 10 to the vicinity of the center portion, but from the vicinity of the center portion. The distance between the upstream side wall portion 27 and the downstream side wall portion 28 of the communication path portion 26 gradually increases until the upstream side wall portion 27 and the downstream side wall portion 28 of the adjacent communication path portions 26 are connected.

  That is, the water that flows from the second opening 16 of the water supply unit 9 to the communication passage portion 26 and does not flow to the humidifying filter portion 8 but flows to the center of the filter frame portion 10 of the communication passage portion 26 is water dispersion means. The water hits a plurality of substantially flat projections 34, and water is dispersed, so that not only the other plurality of communication passage portions 26, that is, the communication passage portion 26 at, for example, 6 o'clock position of the timepiece, but also about 4 o'clock of the timepiece. From 5 o'clock and from 7 o'clock to 8 o'clock of the timepiece, it is easy to flow into the communication passage portion 26. As a result, since water flows into the humidifying filter portion 8 from the plurality of communication passage portions 26, water can be supplied to a wider area of the humidifying filter portion 8, and water can be supplied almost evenly to the wide area of the humidifying filter portion 8.

  Moreover, as shown in FIGS. 6 and 8, the filter frame portion 10 has a drain hole portion 35 opened on the outer peripheral surface on the downstream side in the rotation direction of the filter frame portion 10 of the first opening portion 15 of the water supply portion 9. The water drain hole 35 is provided with water film preventing means. The water film preventing means of the filter frame portion 10 includes a communication hole portion 36 that opens on the surface of the filter frame portion 10 that communicates with the drain hole portion 35, and a drain hole from the inside of the communication hole portion 36. The flat plate portion 37 is formed in a substantially flat plate shape extending so as to face the hole portion 35, and the axial dimension of the filter frame portion 10 of the flat plate portion 37 is that of the drain hole portion 35 of the drain hole portion 35. The structure is larger than the dimension in the axial direction.

  Specifically, in the downstream filter frame 18 of the filter frame portion 10, a drain having an approximately square shape opened in the cylindrical portion on the downstream side in the rotation direction of the filter frame portion 10 of the first opening portion 15 of the water supply portion 9. A hole 35 is provided, and the drain hole 35 is provided with water film preventing means. The water film preventing means includes a communication hole 36 opened on the surface of the upstream side of the upstream filter frame 17 communicating with the water drain hole 35, and a drain hole 35 from the inside of the communication hole 36. Is formed with a flat plate portion 37 having a substantially rectangular flat plate shape extending from the upstream filter frame 17 portion so as to face the filter, and the axial dimension of the filter frame portion 10 of the flat plate portion 37 is the filter of the drain hole portion 35. It is configured to be larger than the axial dimension of the frame portion 10, that is, to protrude from the water drain hole portion 35 to the downwind side of the wind path.

  That is, when performing maintenance of the humidifying filter portion 8, the filter frame portion 10 is removed from the water tank 7. At this time, a water drain hole portion 35 is provided so that water in the filter frame portion 10 flows out quickly. . For example, if this drain hole 35 is provided on the outer peripheral surface of the filter frame 10 and no water film preventing means is provided, the filter frame 10 is rotated by the rotating means 12 so that the drain hole 35 is in the water tank. 7 is immersed in the water, and a water film is formed in the drain hole 35. The water film is blown from the drain hole 35 on the outer peripheral surface of the filter frame 10 to the outside of the filter frame 10 by blowing air. It will jump out. Therefore, when the drain hole 35 is provided on the outer peripheral surface of the filter frame 10 and a water film preventing means is provided in the drain hole 35, the water film is connected to the wind path leeward end of the drain hole 35. The air path leeward side end of the flat plate portion 37, which is a water film prevention means, can be connected to the air path leeward side end portion of the flat plate portion 37. Since the water film is located more on the downwind side of the wind path, the water film jumps to the humidifying filter unit 8 without jumping out to the outside of the filter frame unit 10, so that the amount of water supplied to the humidifying filter unit 8 can be increased.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, and humidifying means provided in the main body case.

A disc-shaped humidifying filter part whose lower end is always immersed in, a water supply part for pumping and supplying water in the water tank to the humidifying filter part, a filter frame part for fixing the humidifying filter part and the water supply part, A rotating means for rotating about the shaft portion at the center of the filter frame portion, and a blowing means for blowing air from the intake port to the exhaust port is provided on the downwind side of the humidifying means, and the water supply The portion is located at the peripheral edge of the filter portion on the wind path upstream side, and is substantially box-shaped and includes a first opening and a second opening, and the first opening is a rotation of the filter frame portion. Opening downstream in the direction, the second The mouth portion includes a communication passage portion that opens in a center direction of the filter frame portion and communicates the second opening portion and the filter portion. The communication passage portion is connected to the filter from the second opening portion. An upstream side wall provided on the upstream side of the rotation direction of the filter frame part of the second opening and extending downstream of the second opening part in the rotation direction of the filter frame part It is formed from the downstream side wall part provided in this, and the windward side wall part which block | closes the wind path wind side between an upstream side wall part and a downstream side wall part, and can improve a humidification capability.

  That is, the water supply unit fixed to the filter frame part rotates to pump water from the first opening and from the second opening to the humidification filter part through the communication path part. Water supply. The communication passage portion is surrounded by the upstream side wall portion, the downstream side wall portion, and the windward side wall portion, and communicates the second opening portion and the filter frame portion, so that the water supply portion is connected to the first opening portion. Until the water in the aquarium is pumped and rotates from approximately 10 o'clock to 12 o'clock (uppermost part), the water mainly flows through the upstream side wall and flows into the humidifying filter part. Until it rotates at approximately 2 o'clock, water mainly flows through the humidifying filter portion while traveling along the downstream side wall portion. Here, since the windward side wall can suppress the influence of the blowing means, the water flows from the peripheral part to the center part of the humidifying filter part, and water can be included in the wind path windward side of the humidifying filter part. It is.

  Based on these results, the humidifying ability can be improved.

  Therefore, it is expected to be utilized as a humidifying device and an air cleaning device with a humidifying function for home use and office use.
