(Embodiment 1)
FIG. 1 is a perspective view of the humidifier 11, FIG. 2 is a configuration diagram showing a cross section at a cross section X in FIG. 1, and FIGS. 3 and 4 are configuration diagrams showing a cross section at a cross section Y in FIG.

  As shown in FIGS. 1, 2, 3, and 4, the humidifier 11 is a housing 14 provided with a suction port 12 for taking in air and a blower outlet 13 for blowing out air. In the housing 14, an impeller 15 for generating an air flow, a motor 16 for driving the impeller 15, an inlet 17 for allowing the air flow to flow into the impeller 15, and a suction port Between the inlet 12 and the inlet 17, a humidifying means 18 rotatably provided below the inlet 17, a tray 19 for supplying water by immersing the lower end of the humidifying means 18, and a tank for replenishing the tray 19 with water 20 is provided.

  The humidifying means 18 includes two knitted fabrics having two openings and a plurality of connecting fibers that connect the two knitted fabrics with an interval therebetween, and sucks water between the knitted fabric and the connecting fibers. It comprises a vaporization filter 21 made of a three-dimensional knitted fabric capable of natural suction and a filter frame 22 for holding the vaporization filter 21 in parallel.

  When the inlet 17 is surrounded by the vaporizing filter 21 as shown in FIG. 3 due to the rotation of the humidifying means 18, the portion located on the lower end side of the vaporizing filter 21 of the humidifying means 18 contacts the water of the tray 19. The air flow generated by the impeller 15 passes through the wet vaporization filter 21 to perform humidification. The rotation of the humidifying means 18 is operated by the timing motor 23 so that the upper and lower sides of the vaporization filter 21 are switched every predetermined time (10 minutes in this case).

  In addition, although the case where the two vaporization filters 21 were shown was shown as an example, it does not restrict | limit in particular to this, Another vaporization filter 21 is provided between the two vaporization filters 21, or two vaporization filters 21 are provided. If there are two or more, such as providing one by one, there is no problem. However, if the number of vaporization filters 21 is too large, the pressure loss increases, so two to six are preferable.

  Moreover, although the solid knitted fabric was shown as an example as the vaporization filter 21, known things, such as a nonwoven fabric, can also be used.

  In addition, a known device such as a stepping motor can be used for the rotation of the humidifying means, and the predetermined time can be freely selected according to the characteristics of the vaporization filter 21.

  Further, the rotation center of the impeller 15 and the rotation center of the humidifying means 18 are provided so as to coincide with each other in the direction of gravity.

  In addition, although the humidification apparatus 11 provided with the tank 20 was shown in this embodiment, the specification which does not provide the tank 20 but supplies water directly to the tray 19 may be sufficient.

  According to such a configuration, it is possible to pass the air flow from the two vaporization filters 21 provided in parallel toward the inflow port 17 through separate air passages. Therefore, the amount of ventilation air per vaporization filter 21 The pressure loss of the vaporization filter 21 can be suppressed even when the amount of air is large. Further, since the rotation center of the impeller 15 and the rotation center of the humidifying means 18 coincide with each other in the direction of gravity, the distance from the inlet 17 to the two vaporization filters 21 provided in parallel is approximately the same. An air flow can be made to pass substantially uniformly through the two vaporization filters 21, and humidification can be performed efficiently.

  Further, since the humidifying means 18 is provided below the inflow port 17 and it is not necessary to provide a special air path from the humidifying means 18 to the impeller 15, the casing 14 can be made compact.

  Further, since the humidifying means 18 is rotatable, impurities in the water such as scale are deposited near the inlet 17 of the vaporizing filter 21, and when dried, the end face of the vaporizing filter 21 can be changed up and down by rotation. The humidification performance can be maintained for a long time.

  In addition, since a three-dimensional knitted fabric is used as the vaporization filter 21, the three-dimensional knitted fabric is flexible. Therefore, when the airflow flows, the three-dimensional knitted fabric is bent at the downstream side of the airflow. Since the surface wind speed can be lowered, the pressure loss of the vaporization filter 21 can be reduced. At this time, as a method of fixing the three-dimensional knitted fabric, the three-dimensional knitted fabric of the vaporization filter 21 is fixed to the filter frame 22 at both ends where the vaporized filter 21 is brought into contact with the water of the tray 19, and the central portion is fixed in a deformable manner. desirable.

  In addition, the three-dimensional knitted fabric is excellent in flexibility and can be washed by washing. Since the vaporization filter 21 can be washed without using a special cleaning agent, the washing is easy and can be used for a long time.

  In the present embodiment, an axial fan (propeller fan) is shown as the impeller 15. However, since the mixed flow fan and the turbo fan can be arranged on the humidifying means 18 without providing an air passage, the casing 14 can be made compact. This is preferable.

  Further, in the present embodiment, as shown in FIG. 4, the humidifying means rotates every predetermined time and replaces the portion of the vaporizing filter 21 that contacts the water of the tray 19, and vaporizes during the rotating operation of the humidifying means. At a position where the filter 21 does not surround the inflow port 17, air volume control means for reducing the rotational speed of the impeller 15 is provided. Thereby, in order to keep the vaporization filter 21 in a wet state, the vaporization filter 21 is rotated, and the rotational speed of the impeller 15 is decreased in a transition period in which the upper and lower sides are switched, and noise is controlled by controlling the air volume. Since it does not increase, it is possible to prevent the user from being stressed by a change in noise.

  As the air volume control means, the vaporization filter 21 is rotated once during operation, the operation time after rotation is measured, the vaporization filter 21 is rotated after a predetermined time has elapsed, and the motor is adjusted in accordance with the rotation time of the vaporization filter 21. The number of rotations of 16 (the number of rotations of the impeller 15) is reduced and the static pressure at the inlet 17 is measured, and the number of rotations of the motor 16 (the number of rotations of the impeller 15) is reduced according to the change in static pressure. The method of making it, etc. are mentioned.

  In the present embodiment, as shown in FIGS. 3 and 4, the water holding member 24 is provided at the end of the vaporizing filter 21 that contacts the water of the tray. In addition, as the water holding member 24, a member excellent in water absorption is preferable, and examples thereof include a sponge-like material containing a highly water-absorbing resin, a knitted fabric containing a highly water-absorbing fiber, and a woven fabric.

  Thereby, since water can be supplied from the water holding member 24 to the vaporization filter 21 on the side not in contact with the water of the tray 19, the vaporization filter 21 on the side not in contact with the water on the tray 19 is prevented from drying. Since the entire vaporization filter 21 can be used in a wet state, it can be humidified efficiently.

  Further, as shown in FIGS. 3 and 4, the water holding member 24 is provided so as to be surrounded by the filter frame 22 and the vaporization filter 21, so that the air flow does not contact the water holding member 24.

  Thereby, since it can suppress that impurities, such as an underwater scale, precipitate on the water holding member 24, the function to hold | maintain the water of the water holding member 24 can be exhibited stably for a long period of time.

Even when the amount of air sucked from the inlet 17 is large, an increase in pressure loss per vaporization filter 21 can be dispersed and suppressed.

  In addition, since the rotation center of the impeller 15 and the rotation center of the humidifying means 18 are configured to coincide with each other in the direction of gravity, the distance from the inlet 17 to the two vaporization filters 21 provided in parallel is substantially the same. An air flow can be made to pass substantially uniformly through the two vaporization filters 21, and humidification can be performed efficiently.

  Further, since the humidifying means 18 is provided below the inflow port 17 and it is not necessary to provide a special air path from the humidifying means 18 to the impeller 15, the casing 14 can be made compact.
