In this way, humidified and purified air that has been subjected to humidification and air purification treatment is supplied. However, since the humidification means is composed of a cylindrical humidification filter, the air blown from the humidification means is first outside the humidification filter. To the inside of the cylindrical humidifying filter, and then from the inside of the cylindrical humidifying filter to the outside of the humidifying filter. That is, since it passes through the humidification filter twice, the ventilation resistance in the humidification means increases.

  In addition, since the intake port, the blower unit, and the exhaust port are located at the upper part of the humidifying unit, the direction of the air blown from the upper part of the humidifying unit is changed inside the cylindrical humidifying filter, and the upper part from the inside of the cylindrical humidifying filter is used. It is blown to the exhaust port. That is, the air flow is changed by about 180 degrees by the humidifying means, and the ventilation resistance is increased.

  Thus, since the ventilation resistance is large, the air volume of the humidified air clean air becomes small.

A part of the water supply unit 8 and the humidifying filter 6 is always immersed in this water. Here, the water supply unit 8 and the humidification filter 6 are rotated by the electric motor 10 that is a rotating means, and the water pumped up by the water supply unit 8 is dripped near the top to wet the humidification filter 6.

  A feature of the present embodiment is that a bypass air passage 12 that connects the air purifying means and the air blowing means 11 is provided, and the humidifying filter 6 and the bypass air passage 12 are provided at a position facing the suction port 13 of the air blowing means 11 and the bypass air flow. That is, a plate-shaped partition plate 14 is provided in the path 12. That is, the bypass air passage 12 connects the air purifying means and the air blowing means 11 without passing through the humidifying filter 6 as the humidifying means, and the air sucked into the main body case 3 from the intake port 1 is the air purifying means. Air is sent from the air cleaning filter 5 to the blowing means 11 via the bypass air path 12 separately from the air cleaning humidification air path that is blown to the blowing means 11 through the humidifying filter 6 that is the humidifying means.

A stage is provided on the downstream side of the humidifying filter, a bypass air passage that connects the air cleaning means and the air blowing means is provided, and the humidifying filter and the bypass air passage are provided at a position facing the suction port of the air blowing means. In the bypass air passage, a plate-shaped partition plate is provided, and the ventilation resistance can be reduced and the air volume of the humidified air can be increased.

  That is, the humidifying means is a disc-shaped humidifying filter, and is provided with a blowing means on the downstream side of the humidifying filter, providing a bypass air passage connecting the air cleaning means and the blowing means, and connecting the humidifying filter and the bypass air passage to the air blowing means. Since it is provided at a position opposite to the suction port, the air sucked from the suction port passes through the air purifying means, passes through the humidification filter and is sucked into the blowing means, and passes through the bypass air passage and sucked by the blowing means. The two air paths are exhausted from the exhaust port into the room by the blowing means. As a result, the number of passes through the humidification filter is halved to 1 and the air flow is not changed in direction by the humidification means. Furthermore, since a bypass air passage not through the humidifying means is provided, the ventilation resistance is reduced. Further, the partition plate can prevent the air from flowing excessively into the air clean air path and increase the air volume of the air clean humidified air path.

  Based on these results, the air volume of the humidified air clean air can be increased.

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