FIG. 10 is a perspective view showing a state in which the humidifying portion connecting member 80 is removed in the air purifying device 1. As shown in FIG. 10, in the air purifying device 1, when the humidifying portion 50 is not attached, the connecting member mounting portion 66 is provided with a cap 81 instead of the humidifying portion connecting member 80, so that the device does not have a humidifying function. It is also available as. Further, even when the air purifying device 1 is used as a device of only the air purifying unit 10 having no humidifying unit 50, the humidifying function is provided by a simple configuration in which the humidifying unit 50 is placed on the upper part of the air purifying unit 10. Can be added. That is, in the air purifying device 1, the humidifying unit 50 is configured to be removable from the upper part of the air purifying unit 10.

As described above, the air purifying device 1 has a first air introduction section 52 and a second air introduction section 55, which are provided in the humidifying section main body 51 so as to face the exhaust port 17, respectively. With this configuration, according to the air purifier 1, the clean air flowing from the first air introduction unit 52 to the ventilation unit 53 and the clean air flowing from the second air introduction unit 55 to the filter accommodating unit 56 are arranged. The humidified air and the air that have passed through the filter 57 impregnated with the humidifying fluid (water) are efficiently discharged to the outside.

In particular, in the air purifying device 1, the air passing through the filter 57 impregnated with water flows from the second air introduction section 55 directly facing the exhaust port 17, to the flow path section 61, the rectifying section 62, and the rectifying section 62. , It is guided to the filter 57 through the air outlet 63 and humidified. That is, in the air purifying device 1, the air flow path from the second air introduction section 55 to the humidified air lead-out section 58 is a flow path from the first air introduction section 52 to the air lead-out section 54 from which the unhumidified air is discharged. It is an independent flow path isolated from. Therefore, according to the air purifying device 1, the purified air can be sufficiently guided to the filter 57, so that humidification can be performed efficiently.

Further, in the air purifying device 1, the air that does not pass through the filter 57 is guided from the first air introduction section 52 directly facing the exhaust port 17 to the air lead-out section 54 via the ventilation section 53 and discharged. To. In the air purifying device 1, the air flow path from the first air introduction unit 52 to the air lead-out unit 54 is from the flow path from the second air introduction unit 55 to the humidified air lead-out unit 58 from which the humidified air is discharged. It is an isolated and independent flow path. That is, in the air purifying device 1, a part of the cleaned air discharged from the air purifying unit 10 is discharged to the outside without humidification, so that the air blowing capacity of the device as a whole can be maintained. ..

Therefore, according to the air purifying device 1, the humidified air can be efficiently discharged to the outside even though the humidifying unit 50 does not have a blowing function.

In the air purifying device 1, the first air introduction unit 52 and the second air introduction unit 55 are configured to cover the openings of the exhaust ports 17, respectively. Further, the area of the opening portion of the humidified air lead-out portion 58 is larger than the area of the opening portion of the air lead-out portion 54. With such a configuration, according to the air purifier 1, the flow rate of the humidified air can be secured, so that the humidifying unit 50 is humidified even though it has a simple configuration without a blowing function. The air can be efficiently discharged to the outside.

The air purifier 1 has a flow path portion 61, a rectifying portion 62, and an outlet 63, and the filter 57 is arranged inside the filter accommodating portion 56 so as to face the outlet 63. Therefore, the rectifying unit 62 rectifies the direction of the air from the lower side to the upper side of the air purifying device 1 toward the filter 57 provided on the outer side in the circumferential direction. With this configuration, the air taken in from the second air introduction unit 55 is efficiently guided to the filter 57.
