  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 air blown into the humidifying filter surface on the leeward side flows down the humidifying filter. In other words, while flowing through the humidification filter from the outer peripheral end face of the humidification filter, it flows into the humidification filter surface on the leeward side without flowing into the central part of the humidification filter. Water could not be included, and it was difficult to increase the air volume and improve the humidification ability.

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

  And 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 being a water tank in which a certain amount of water is stored, A disk-shaped humidifying filter whose lower end is always immersed in the water of the water tank and a rotating means for rotating the humidifying filter, and a blowing means for blowing air from the intake port to the exhaust port.

  Hereinafter, the present embodiment will be described with reference to the accompanying drawings.

(Embodiment 1)
As shown in FIGS. 1, 2, 3, 4, and 5, the humidifier according to the present embodiment includes a main body case 3 having an intake port 1 on a side surface and an exhaust port 2 on a top surface, and the main body case 3. Humidifying means is provided inside. The humidifying means is formed of a moisture release portion, a water supply portion, and a rotating means for rotating the moisture release portion. The moisture release portion is formed of a disk-shaped humidification filter 4 and a humidification filter frame 5 fixed to the humidification filter so as to be rotatable. The humidification filter frame 5 includes a water supply case 6 on the outer periphery. A rotating shaft 7 is provided at the center. The water supply portion is formed by a substantially bowl-shaped water tank 8 provided at the lower part of the humidifying filter 4 and a water tank 10 for supplying a constant amount of water 9 to the water tank 8. On the downstream side of the humidification filter 4, there is provided a blower fan 11 that blows air that has been sucked into the main body case 3 from the intake port 1 into the exhaust port 2 through the humidification filter 4.

  The humidifying operation with the above configuration will be described. The humidifying filter frame 5 is provided so that a part of the water supply case 6 and the humidifying filter 4 of the humidifying filter frame 5 are always immersed in the water 9 supplied to the water tank 8, and in this state, the humidifying filter frame 5 is rotated by rotating means. Let By the rotation, the water supply case 6 of the humidifying filter frame 5 pumps up a certain amount of water 9 supplied from the water tank 10 to the water tank 8, supplies the humidifying filter 4 with water, and causes the humidifying filter 4 to contain moisture. Then, the air sucked into the main body case 3 from the air inlet 1 by the blower fan 11 is blown to the humidifying filter 4 to humidify the air, and the humidified air is blown to the exhaust port 2.

  The feature in this embodiment is the structure of the moisture release part and water supply part in a humidification means. That is, the humidifying filter 4 is provided in a conical shape in which the upwind side is convex in the humidifying filter frame 5, and the humidifying filter frame 5 is rotated by rotating means so that the water is supplied from the water tank 8 in the water supply case 6 of the humidifying filter frame 5. 9 is pumped up and supplied to the windward side of the upper center of the humidifying filter 4.

  The rotating shaft portion 7 extends outward from both side surfaces of the central portion of the humidifying filter frame 5, and between the rotating shaft portions 7 on both side surfaces, the rotating shaft portion 7 on the leeward side is inside the humidifying filter frame 5. The filter fixing | fixed part 12 extended in this is provided. When the humidifying filter 4 is attached to the humidifying filter frame 5, it becomes a conical shape having a convex shape on the windward side by the filter fixing part 12 at the center of the humidifying filter frame.

  That is, the humidifying filter 4 is provided in a conical shape having a convex shape on the windward side, and water is supplied from the water supply portion of the humidifying means to the windward side of the upper peripheral portion of the humidifying filter 4. The water 9 thus flowed down flows along the surface of the windward humidification filter 13. The water flowing down the surface of the windward side humidifying filter 13 flows into the humidifying filter 4 by the air blown by the blower fan 11. Further, the outer peripheral portion of the humidifying filter 4 includes water 9 by being immersed in the water 9 accumulated in the water tank 8 in the vicinity of the lowest point when the humidifying filter 4 rotates, and is included in the outer peripheral portion of the humidifying filter 4 near the uppermost point. Excess water 9 will flow into the upper center of the humidifying filter 4.

  That is, the water 9 supplied to the upper center of the humidifying filter 4 flows down the upwind side surface of the humidifying filter 4 due to gravity and flows into the humidifying filter 4 by wind force. Since the excess water 9 contained in the outer periphery of the humidifying filter 4 flows into the upper center of the humidifying filter 4 due to gravity, the water 9 can be contained in the entire humidifying filter 4. .

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

  Further, the humidifying filter 4 will be described. The humidifying filter 4 has a three-layer structure in which a second layer 15 is sandwiched between two planar first layers 14, and the second layer 15 is a first layer 15. It is formed by a plurality of yarns perpendicular to the layer 14. That is, the second layer 15 is a three-dimensional structure in which the first layer 14 is connected by fibers.

  Specifically, a plurality of openings 16 adjacent to each other are provided on the surface of the planar first layer 14, and the openings 16 are formed in a circular shape or a polygonal shape. Since the edges of the circular or polygonal openings 16 that are the two planar first layers 14 are connected by the plurality of threads that are the second layer 15, the circular or polygonal shapes are connected by the plurality of threads. A cylindrical shape is formed.

  That is, the water 9 supplied to the humidifying filter 4 travels along the edge of the circular or polygonal opening 16 that is the surface of the flat first layer 14 that is the surface of the humidifying filter 4 on the windward side by gravity. As it flows down, the edge of the circular or polygonal opening, which is the first layer 14, flows into the humidifying filter 4 through the second layer 15 connected by a plurality of yarns, and flows into the humidifying filter 4. As a result, the water 9 can be contained in the second layer 15 in the humidifying filter 4. Based on these results, the humidifying ability can be improved.

  The humidifying filter frame 5 will be described. A plurality of water supply cases 6 are provided on the outer peripheral edge of the humidifying filter frame 5, and the water supply cases 6 have a predetermined distance from the adjacent water supply cases 6. The water supply case 6 has a water supply / drainage part 17 having a substantially box shape and one side opened, and a spout part 18 is provided at a lower part of the water supply / drainage part 17. Here, when the humidifying filter frame 5 is rotated by the rotating means, and the water supply case 6 is positioned at the uppermost point, the spout portion 18 is directed downward.

  Specifically, the humidifying filter frame 5 which is a moisture releasing portion of the humidifying means includes a plurality of water supply cases 6 on the outer peripheral portion and a rotating shaft portion 7 on the central portion. An annular gear 19 is provided between the water supply case 6 and the rotary shaft portion 7. Therefore, the gear provided in the electric motor as the rotating means rotates, and the rotation is transmitted to the gear 19 to rotate the humidifying filter frame 5 and the humidifying filter 4. As the humidifying filter frame 5 rotates in this way, a plurality of horizontally long box-shaped water supply cases 6 that are water supply cases 6 rotate. Therefore, first, when the water supply case 6 rotates and comes near the lowest point, it enters into the water 9 of the water tank 8, where water 9 enters the water supply case 6 from the water supply / drainage part 17 of the water supply case 6. Next, the water 9 is rotated with the water 9 in the water supply case 6, and when it comes near the uppermost point, the water 9 drops from the water supply case 6 from the spout part 18 of the water supply / drainage part 17 of the water supply case 6.

  That is, a plurality of water supply cases 6 are provided on the outer peripheral edge of the humidifying filter frame 5, and the water supply case 6 has a predetermined distance from the adjacent water supply case 6, and covers all the outer peripheral edges of the humidifying filter 4 with the water supply case 6. Since there is nothing, the reduction of the surface area of the humidifying filter 4 can be suppressed. Further, the water supply case 6 has a water supply / drainage part 17 having a substantially box shape and one side opened, a spout part 18 is provided at the lower part of the water supply / drainage part 17, and the humidifying filter frame 5 is rotated by rotating means. When the uppermost point is located, the spout 18 is directed downward, so that the water supply case 6 is supplied with water when the uppermost point is located, and the supplied humidifying filter frame 5 is at a higher position so that water is supplied. Thus, the water 9 flows from the humidifying filter portion to a wide range of the humidifying filter 4, and as a result, the entire humidifying filter 4 is likely to contain the water 9, thereby improving the humidifying ability.

  The spout portion 18 has a predetermined distance from the humidifying filter 4. Specifically, the spout portion 18 is located in the axial direction of the humidifying filter frame 5 and approximately in the middle between the outer peripheral end and the central portion of the humidifying filter 4. Thereby, the water 9 that has flowed down from the spout portion 18 of the water supply case 6 can be dropped to the center upper portion of the humidifying filter 4.

  Further, the water supply case 6 is rotated together with the humidifying filter frame 5 by the rotating means, and when the water 9 in the water tank 8 is pumped up, a part of the water supply / drainage part 17 of the water supply case 6 is always located above the water surface. That is, when the water supply case 6 rotates and enters the water in the water tank 8, air is introduced from the lower part of the water supply / drainage part 17 of the water supply case 6 into the water supply case 6, and air is supplied from the upper part of the water supply / drainage part 17 of the water supply case 6. Since the water 9 is stored in the water supply case 6, the water 9 can be easily stored in the water supply case 6.

  The water supply case 6 is detachably provided on the humidifying filter frame 5. Specifically, the humidifying filter frame 5 includes a water supply case 6 fixing claw. The fixing claw can be used for detachment.

  Thereby, since the water supply case 6 which has the water supply / drainage part 17 which the one side surface opened from the humidification filter frame 5 can be easily removed, the water supply case 6 can be cleaned easily.

  Further, the aquarium 8 has a substantially horizontally long box shape with an open top, and the height of the lateral side surface portion of the laterally long side surface is lower at the center than the end portion. The humidifying filter frame 5 is rotatably disposed on the other end side. Specifically, when viewed from the front side of the main body case 3, the water tank 10 is provided at the right end, and the humidification filter 4 is provided from the left end to the center.

  That is, the water tank 8 has a substantially horizontally long box shape with an open top, and the height of the horizontally long side surface portion of the horizontally long side surface is lower than the end portion, and a portion corresponding to approximately half the area of the humidifying filter 4 is present in the center portion. It is what is located. Thereby, the air passage area in which the air sucked into the main body case 3 from the air inlet 1 by the blower fan 11 is blown to the humidifying filter 4 without hitting the laterally long side surface portion of the water tank 8 is increased. Air will pass almost uniformly over a wide range, and as a result, the humidifying ability can be improved.

  Further, a water tank 10 for supplying a constant amount of water 9 to the water tank 8 is provided on one end side in the lateral direction of the water tank 8, and a humidifying filter frame 5 is rotatably disposed on the other end side, and is humidified by rotating means. The water supply case 6 of the filter frame 5 is configured to rotate in the direction of the center from the other end side after pumping up the water 9 from the water tank 8. Specifically, when the water supply case 6 rotates and comes near the lowest point, the water 9 enters the water 9 of the water tank 8, where the water 9 enters the water supply case 6 from the water supply / drainage part 17 of the water supply case 6. Next, when the water 9 is rotated with the water 9 in the water supply case 6 and comes to the vicinity of the uppermost point, the water 9 in the water supply case 6 drops from the spout part 18 of the water supply / drainage part 17 of the water supply case 6 and the humidifying filter 4. To be supplied with water. Here, when the humidifying filter 4 further rotates, the humidifying filter portion including the most water 9 immediately after being supplied with water rotates the central portion of the water tank 8.

  That is, the humidifying filter portion containing the most water 9 immediately after being fed rotates in the central portion where the air passage area blown to the humidifying filter 4 without hitting the horizontally long side portion of the water tank 8 rotates, so that the humidifying ability is improved. I can do it.

  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 includes a water tank in which a certain amount of water is stored, and water in the water tank. Is formed from a disc-shaped humidifying filter whose lower end is always immersed in the surface, and a rotating means for rotating the humidifying filter, and the humidifying filter is provided on the upstream side of the blowing means for blowing air from the intake port to the exhaust port. The humidifying filter is provided in a conical shape having a convex shape on the windward side, and is provided with a water supply section for supplying water to the windward side at the upper center of the humidifying filter, so that the humidifying ability can be enhanced.

  In other words, the humidification filter is provided in a conical shape with a convex shape on the windward side of the water supply unit, and water is supplied from the water supply unit of the humidification means to the windward side of the upper center of the humidification filter. Water flows down along the humidifying filter surface on the windward side. The water that flows down the humidifying filter surface on the windward side flows into the humidifying filter by the air blown by the blowing means. Also, the humidifying filter outer periphery contains water by rotating the humidifying filter and immersing it in the water stored in the water tank near the lowest point, and excess water contained in the outer peripheral part of the humidifying filter near the uppermost point is the humidifying filter. It will flow into the upper center.

  In other words, the water supplied to the upper center of the humidifying filter flows down the upwind side of the humidifying filter due to gravity and flows into the humidifying filter by wind force. In addition to flowing in, excess water contained in the outer periphery of the humidifying filter flows into the center of the humidifying filter due to gravity, so water can be contained in the entire humidifying filter.

  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.
