Description

  The present invention relates to a humidifier that vaporizes water absorbed by a humidifying filter to humidify air.

  As this type of humidifier, the lower part of the humidifying filter is submerged and water is absorbed into the humidifying filter by capillary action, and water is dripped from the upper part of the humidifying filter, and the water accumulated in the lower part of the humidifying filter is returned to the upper part of the humidifying filter. There is a method of pushing up and supplying water to the humidifying filter while forcibly circulating water.

Further, Patent Document 1 discloses a humidifier that rotates a disk-shaped humidifying filter to distribute water evenly throughout the entire humidifying filter and includes the entire humidifying filter in a short time.
JP 2003-294277 A

  By the way, in the case of the above-mentioned natural water absorption method, since there is a limit to the height to be absorbed, the height of the humidifying filter is restricted. In addition, the water retention amount of the humidifying filter cannot be adjusted, and the humidifying amount is left to the ventilation rate.

  In addition, in the case of the water circulation method, it is difficult to adjust the amount of water hung on the humidifying filter, and a pump and a circulation channel for circulating water are required, and the apparatus itself is expensive.

  Further, in the case of the rotary humidifying filter of Patent Document 1, a water scraping portion is formed on the outer peripheral portion of the humidifying filter, and a part of the water scraping portion is submerged in the humidifying tray, but the entire filter body can be rotated to a position where it is not always submerged. Thus, the rotation of the humidifying filter is stopped, and the supply of water from the water scraping portion to the filter main body is stopped. However, in Patent Document 1, since it is necessary to set the position of the humidifying tray so that a part of the water scraping part is always submerged and the filter body is not submerged, it is very difficult to adjust the height of the humidifying filter. There were difficulties.

  In view of the above, an object of the present invention is to provide a humidifier that can easily set the supply / stop of water to a humidification filter.

  In order to achieve the above object, the present invention provides a blowing means for sending air sucked from the suction port of the apparatus main body to the outlet, a humidifying filter for humidifying the air sent by the blowing means, and a lower portion of the humidifying filter. A humidifying tray to be immersed, and the humidifying filter is rotatably supported by the apparatus main body around the rotation axis, and the distance from the rotation axis center to the outer periphery is non-uniform, and the humidification filter is placed at a predetermined position. When stopped, it is not in contact with water in the humidifying tray.

  According to the said structure, water can be uniformly supplied to a humidification filter with a rotary humidification filter, and water can be included in the whole humidification filter in a short time. In addition, since the distance from the rotation shaft center to the outer periphery of the humidifying filter is made non-uniform, when the humidifying filter is stopped at a predetermined position, it can be brought into a non-contact state with the water in the humidifying tray. That is, the humidifying filter can be floated from the water surface of the humidifying tray, and the height of the humidifying filter can be easily adjusted.

  Here, when the distance from the rotation axis center to the outer periphery of the humidifying filter is not uniform, for example, the humidifying filter may be formed in an elliptical shape or a rectangular shape when viewed from the axial direction of the rotating shaft. Can be mentioned. In the case of an ellipse, it can be submerged in the humidifying tray when the long axis is positioned in the vertical direction, and can float from the water surface of the humidifying tray when the short axis is positioned in the vertical direction. Further, in the case of a rectangle, it can be submerged in the humidifying tray when the long side is positioned in the vertical direction, and can be floated from the water surface of the humidifying tray when the short side is positioned in the vertical direction.

  Moreover, a humidification filter can maintain the humidification amount high by making the axial direction of the rotating shaft the ventilation direction.

  Moreover, the humidification filter can form the water scraping part which scoops up and hold | maintains water at the outer peripheral part. This water scraping part can surely pump water from the humidifying tray as the humidifying filter rotates. Therefore, even if the submerging amount of the humidifying tray is small, water can be reliably supplied to the humidifying filter.

  As described above, according to the present invention, the humidification filter is formed in a rectangular or elliptical shape, and the distance from the center of the rotation axis to the outer periphery is uneven. Therefore, when the humidification filter is stopped at a predetermined position, The water can be easily brought into a non-contact state, and the height of the humidifying filter can be easily adjusted.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a schematic configuration of a humidifying device showing an embodiment of the present invention, FIG. 2 is a plan sectional view thereof, and FIG.

  The humidifying device of the present embodiment includes a blowing unit 4 that sends air sucked from the suction port 2 of the apparatus main body 1 to the outlet 3, a humidifying filter 5 that humidifies the air sent by the blowing unit 4, and the humidifying filter. And a humidifying tray 6 in which the lower part of 5 is immersed, and the humidifying filter 5 is supported by the apparatus body 1 so as to be rotatable about the rotating shaft 7 and makes the distance from the rotating shaft center to the outer periphery nonuniform. It is formed in an elliptical shape so as to be in non-contact with the water in the humidifying tray 6 when the humidifying filter 5 is stopped at a predetermined position.

  The apparatus main body 1 is formed in a vertically long box shape, and an air suction port 2 for sucking air is formed in the front panel 1a. The interior of the apparatus main body 1 includes a filter storage chamber 8 disposed behind the air inlet 2, a fan storage chamber 9 formed on the rear side thereof, and a tank storage formed on the side of the fan storage chamber 9. A compartment is formed with the chamber 10. The air passage in the apparatus main body 1 extends from the air suction port 2 through the filter storage chamber 8 and the fan storage chamber 9 to the air outlet 3 on the upper surface of the apparatus main body.

  The humidifying filter 5 includes an elliptical filter main body 11 that rotates about a rotating shaft 7 and a scooping portion 12 that is formed in a bowl shape over the entire outer periphery of the filter main body 11, and a rotary drive motor such as a stepping motor. 13 is rotated.

  The filter main body 11 is a non-woven fabric having a predetermined thickness with water absorption formed in a zigzag shape, and vaporizes water absorbed on the filter surface.

  Water is supplied to the humidifying tray 6 from the water tank 14 at the end in the left-right direction. The water tank 14 stores water for humidification and is detachably installed in the tank storage chamber 10. When a water stop valve 16 is provided at the joint 15 at the lower end of the water tank 14 and the water tank 14 is attached to the humidifying tray 6, the valve presser at the water supply port of the humidifying tray 6 opens the water stop valve 16, and the water tank 14 The water is supplied to the humidifying tray 6. When the water tank 14 is removed, the water stop valve 16 is closed to prevent water leakage.

  The air blowing unit 4 includes a sirocco fan 18 provided in the fan housing portion 9 of the apparatus main body 1 and a fan motor 19. The blower 4 controls the rotational speed of the fan motor 19 so that the air volume is increased when a large amount of humidification is generated, and the air volume is decreased when the humidity is decreased.

Further, the fan housing portion 9 may be provided with an ion generating element (not shown) that generates positive and negative ions downstream of the fan 18 in the air blowing direction. The ion generating element generates H ⁺ (H ₂ O) _{m which} is a positive ion and O ₂ ⁻ (H ₂ O) _n which is a negative ion (m and n are arbitrary natural numbers) in the air. Both ions surround airborne fungi and viruses in the air and inactivate fungi and the like by the action of hydroxyl radicals (.OH) of active species generated at that time.

  In the above configuration, when the air blowing means 4 is driven, indoor air is taken into the apparatus main body 1 from the air suction port 2. The air taken in from the suction port 2 is supplied to the humidifying filter 5, and the water held in the humidifying filter 5 is vaporized and taken into the air flowing through the air passage. The humidified air flows from the filter storage chamber 8 into the fan storage chamber 9 and is discharged from the blowout port 3 into the room.

  At this time, since the humidification filter 5 is a rotary type, the water scraping part 12 lifts the water in the humidification tray 6 and supplies it to the filter body 11, so that the entire humidification filter can be included in a short time. . In addition, since the humidifying filter 5 is formed in an elliptical shape in which the distance from the center of the rotating shaft 7 to the outer periphery is non-uniform, when the humidifying filter 5 is stopped at a predetermined position, the water in the humidifying tray 6 It becomes a non-contact state. For this reason, the humidifying filter is immediately dried, and propagation of germs can be suppressed.

  In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added within the scope of the present invention. For example, in the above-described embodiment, an elliptical humidification filter is illustrated, but other than this, a humidification filter having an irregular shape such as a rectangle, a triangle, and a D shape may be used. Further, in addition to the above-described embodiment, a heating body for heating air is provided on the upstream side in the air blowing direction from the humidifying filter, and the humidifying amount is increased by supplying the air to the humidifying filter by heating.
