  In such a conventional humidifying device, in the case of a cylindrical humidifying filter, the humidifying filter is washed with water in the aquarium by rotation, so the adhesion of scales etc. to the humidifying filter is reduced and the humidifying performance is maintained for a long time. However, since the concentration of scale components in the water tank is increased by cleaning the humidifying filter, there is a problem that the water tank needs to be frequently maintained.

  Then, this invention solves the said conventional subject, and it aims at reducing the concentration of the scale to a water tank part, and reducing a maintenance frequency.

And in order to achieve this object, the present invention includes a main body case having a suction port for taking in indoor dry air and a blowout port for sending moist air into the room, and the suction port in the main body case. A blower disposed in an air passage connecting the air outlet, a water tank part, a water tank for supplying water for supplying a certain amount of water to the water tank part, and a cylindrical shape, the central axis of which is formed in the water tank part A cylindrical vaporization filter that immerses a portion located below the central axis in parallel with the water surface of the water and rotation means that enables rotation of the vaporization filter, and is sucked from the suction port by the blower In the humidifier that passes the air through the vaporization filter and blows out from the outlet, the scale concentration part formed using a material that can be sucked naturally is not immersed in the water in the water tank part. Sea urchin, the provided convex and in contact with the inner peripheral wall of the vaporizing filter, which outer edge closest vaporization filter at one end of the scale buildup portion is characterized in that it does not immersed in water in the water tank unit, This achieves the intended purpose.

A blower disposed in the water tank, a water tank for supplying a certain amount of water to the water tank, and a cylindrical shape, the central axis of which is parallel to the water surface in the water tank. A cylindrical vaporization filter that immerses a portion located at a lower part, and a rotation unit that enables rotation of the vaporization filter, and the air that has been sucked in from the suction port by the blower is used as the vaporization filter. In the humidifying device that is passed through and blown out from the air outlet, the inside of the vaporization filter has an end that does not immerse the scale concentration part formed using a material capable of sucking up naturally in the water in the water tank part. Due to the configuration in which the wall is convex and in contact with the wall, the scale concentration part absorbs the water of the vaporization filter by the natural suction function in the vaporization filter part located on the air passage side by the rotating means. As a result, the scale remaining in the vaporization filter is absorbed together with the water, so that the concentrated scale remains in the vaporization filter, and the scale moves from the immersed portion of the vaporization filter to the water in the water tank. It is suppressed.

  As a result, it is possible to provide a humidifier that suppresses the precipitation of scale in the water tank and the vaporization filter, and suppresses the necessary maintenance frequency of the water tank and the vaporization filter.

A blower disposed in an air passage communicating with the outlet, a water tank part, a water tank for supplying water for supplying a certain amount of water to the water tank part, and a cylindrical shape, the central axis of which is the water surface in the water tank part A cylindrical vaporization filter that immerses a portion located below the central axis in parallel, and a rotation means that enables rotation of the vaporization filter, and is sucked from the suction port by the blower In the humidifying device that passes through the vaporization filter and blows out from the outlet, so as to have one end that does not immerse the scale concentration part formed using a material that can be sucked naturally in the water in the water tank part, Said Reduction provided convex and in contact with the inner peripheral wall of the filter, and absorbs the scale contained in the water and moisture of the vaporization filter.

  Thereby, in the part of the vaporization filter located on the air passage side by the rotating means, the scale concentration part absorbs the water of the vaporization filter by the natural suction function, and the scale remaining in the vaporization filter is absorbed together with the water. Therefore, it is suppressed that the concentrated scale remains in the vaporization filter, and the movement of the scale from the portion in which the vaporization filter is immersed to the water in the water tank portion is suppressed.

  As a result, it is possible to provide a humidifier that suppresses the precipitation of scale in the water tank and the vaporization filter, and suppresses the necessary maintenance frequency of the water tank and the vaporization filter.

  Moreover, since the end of a scale concentration part is not immersed in a water tank part, the movement of the scale from the end of the scale concentration part where a scale density | concentration becomes high to the water of a water tank part is also suppressed.

  As shown in FIGS. 1, 2, and 3, the humidifier 11 includes a box body in which a main body case 14 having an inlet 12 for taking in indoor dry air and an outlet 13 for sending moist air into the room is formed. It is.

  As shown in FIG. 2, in the main body case 14, a certain amount of air is supplied to the air blower 15, the water tank part 19, and the water tank part 19 disposed in the air passage connecting the suction port 12 and the air outlet 13. A water supply water tank 20 for supplying water and a cylindrical shape that is formed in a cylindrical shape and that has a central axis 21 disposed in parallel with the water surface in the water tank portion 19 and immerses a portion located below the central axis 21. A vaporizing filter 22, a rotating unit 23 that enables the vaporizing filter 22 to rotate, and a humidifying unit 27 that includes the vaporizing filter 22 and a filter frame 28 for providing the vaporizing filter in parallel.

  As shown in FIG. 3, the vaporizing filter 22 includes a scale concentrating portion 24 formed of a material that can be sucked naturally, so that it can be detached from the inner peripheral wall 25 toward the inside of the cylinder.

  The scale concentrating part 24 is convexly brought into contact with the inner peripheral wall 25 of the vaporizing filter 22 so as to have one end 26 that is not immersed in the water of the water tank part 19.

  Further, a plurality of scale concentrating portions 24 are provided at substantially equal intervals on the inner periphery of the vaporization filter 22.

  The humidifying means 27 of the present embodiment is wetted by the rotation of the vaporization filter 22 such that the portion located on the lower end side of the vaporization filter 22 contacts the water in the water tank unit 19 as shown in FIG. The generated air flow is humidified by passing through a portion located above the central axis 21 of the vaporization filter 22.

  For the rotation of the vaporizing filter 22, a known motor such as a timing motor or a stepping motor can be used, and the predetermined time can be freely selected according to the characteristics of the vaporizing filter.

  In addition, although the humidifier 11 provided with the water tank 20 for water supply was shown in this embodiment, the specification which supplies water directly to the water tank part 19 without providing the water tank 20 for water supply may be sufficient.

  In the above configuration, the rotation means 23 causes a part of the vaporization filter 22 to suck in water having a scale concentration equivalent to that of the water tank part 19 when immersed in the water tank part 19, and then is positioned above the central shaft 21. The air passing through the portion that is located on the air passage side is humidified.

  At this time, in the portion located on the air path side of the vaporization filter 22, the scale collecting portion 24 absorbs the water of the vaporization filter 22 by the natural suction function, and absorbs the scale remaining in the vaporization filter 22 together with the water. Therefore, in order to suppress that the concentrated scale remains in the vaporization filter 22, the movement of the scale from the vaporization filter 22 to the water of the water tank part 19 by immersion is suppressed.

  Moreover, since the one end 26 of the scale concentrating part 24 is not immersed in the water tank part 19, the movement of the scale from the one end 26 of the scale concentrating part 24 to which the scale concentration becomes high to the water in the water tank part 19 is also suppressed. As a result, scale concentration and precipitation in the water tank and the vaporization filter 22 are suppressed, and the necessary maintenance frequency of the water tank and the vaporization filter is suppressed.

  In addition, the concentration speed | rate of the calcium and magnesium ion contained in a scale can be improved by comprising the scale concentration part 24 with ion exchange resins, such as a strong acidic cation exchange resin.

  In addition, since a plurality of scale concentrating portions 24 are provided at substantially equal intervals on the inner periphery, the influence of the position of the scale concentrating portion 24 on the flow path can be reduced regardless of the rotation position of the vaporization filter 22. In particular, since the portion between the scale concentrating portions 24 is the main air passage, the humid air passage can be evenly secured regardless of the rotation position of the vaporizing filter 22, and the humidification amount can be stabilized. In addition, it becomes possible to make the scale deposition distribution of the vaporization filter 22 more uniform.

  The scale concentrating part 24 is configured to be detachable from the inner peripheral wall 25 of the vaporization filter 22. With such a configuration, it is possible to periodically replace the scale concentration unit 24 with a new one, maintain the function of the scale concentration unit 24, and reduce the maintenance frequency of the water tank unit and the vaporization filter. It becomes possible.

  In the present embodiment, the three scale concentrators 24 are configured, but the number of scale concentrators 24 may be arbitrarily set. Further, although an axial fan (propeller fan) is shown as the blower 15, in order to make the main body case 14 compact because a mixed flow fan or a turbo fan can be arranged without providing an air path on the humidifying means 27. Is preferred.

  With the above configuration, after the user stops the humidifier 11, the rotation means 23 is completely stopped only when the two magnetic switches 30 approach each other, for example, as shown in FIG. In order to stop the humidifier 11 at a position where the portion in contact with the concentration part 24 is not immersed in the water tank part 19, after the humidification apparatus 11 is stopped, the water from the one end of the scale concentration part 24 having a high scale concentration to the water in the water tank part 19 is transferred. The movement of the scale is suppressed, and it is possible to suppress an increase in the scale concentration of the water tank unit when the humidifier 11 is stopped.
