When the fan section 14 is rotated by the motor section of the blower 3, air is blown into the air path 12. When the fan section 14 rotates, the external air that has entered the main body case 2 from the air intake port 7 is The water is blown out from the main body case 2 via the purification section 4 (water storage container 19, filter 26), blower 3, and outlet 8.

FIG. 5 is a perspective view of the air purifying device according to Embodiment 1 of the present invention with a storage member attached thereto. FIG. 6 is a perspective view of the storage member of the air purifying device according to Embodiment 1 of the present invention. FIG. 7 is a cross-sectional view of the air purifying device according to Embodiment 1 of the present invention with a storage member attached thereto.

As shown in FIGS. 5, 6, and 7, the present embodiment is characterized by having a hollow storage member 30 that can store small items, and the storage member 30 is detachable from the air outlet 8. When the member 30 is attached to the outlet 8, the air blown out from the outlet 8 enters the storage member 30.

Specifically, the storage member 30 includes a duct portion 31, a detachable portion 32, and a bag portion 33.

The duct part 31 has a cylindrical shape with an air passage inside, has a detachable part 32 at one open end of the duct part 31, and can store small items at the other open end of the duct part 31. It has a bag portion 33. The duct portion 31 communicates the detachable portion 32 and the bag portion 33, and air blown from the outlet 8 to the detachable portion 32 flows into the bag portion 33 via the duct portion 31.

The attachment/detachment part 32 has a structure that can be attached to and detached from the air outlet 8, which has a horizontally long rectangular cylinder shape and whose central axis extends in the vertical direction. The attachment/detachment part 32 has an oblong box shape with an open bottom surface, and has a first hole 34 in the top surface. A duct portion 31 extends from the first hole 34 . The removable part 32 is one size smaller than the air outlet 8 which is shaped like an oblong rectangular cylinder. When the removable part 32 is inserted into the air outlet 8 from the upper opening of the air outlet 8 which is shaped like an oblong rectangular cylinder, it is inserted into the air outlet 8. It has a structure that fits.

The bag portion 33 is approximately box-shaped and has an opening 35 on the top surface that can be opened and closed. Small items can be taken in and out through the opening 35. The bag portion 33 has a hole 36 on one side surface, from which the duct portion 31 extends, and the other side surface of the bag portion 33 has a discharge port 37 through which air blown into the bag portion 33 blows out. have. The air containing hypochlorous acid blown out from the outlet 8 flows into the bag section 33 via the detachable section 32 and the duct section 31 in order, sterilizes small items inside the bag section 33, and then is discharged from the outlet 37. It flows into the room. The open end on one side of the duct portion 31 is detachable from the first hole 34 of the attachment/detachment portion 32, and the open end on the other side of the duct portion 31 is detachable from the hole 36 of the bag portion 33.

In this way, the storage member 30 is detachable from the air outlet 8, so when the storage member 30 is attached to the air outlet 8, hypochlorous acid is intensively blown onto the small items placed in the storage member 30, thereby sterilizing them. Spot sterilization can be performed. Further, when the storage member 30 is removed from the air outlet 8, space sterilization can be performed to sterilize the entire room in which the air purifying device is placed.

FIG. 8 is a perspective view of the air purifying device according to Embodiment 1 of the present invention with a storage member attached thereto, with the opening adjustment section 39 in an open state. FIG. 9 is a perspective view of the air purifying device according to Embodiment 1 of the present invention with a storage member attached thereto, with the opening adjustment section 39 in a closed state.

Further, as shown in FIGS. 8 and 9, the detachable part 32 is configured to cover a part of the air outlet 8. As shown in FIGS. The attachment/detachment part 32 has a second hole 38 on the top surface. As a result, a part of the air containing hypochlorous acid that has flowed into the attachment/detachment part 32 from the air outlet 8 flows into the bag part 33 from the first hole 34 via the duct part 31 , and the inside of the bag part 33 . Small items are sterilized and flowed into the room from the discharge port 37. Similarly, a portion of the air containing hypochlorous acid that has flowed into the attachment/detachment section 32 from the air outlet 8 flows out into the room through the second hole 38 . In this way, while purifying the indoor air, small items inside the storage member can be sterilized at the same time.

Further, the attachment/detachment section 32 includes an opening adjustment section 39 that adjusts the opening area of the air outlet 8 that is not covered by the attachment/detachment section 32 . That is, the opening adjustment section 39 adjusts the opening area of the second hole 38 of the attachment/detachment section 32. Specifically, the opening adjustment section 39 includes a slide plate 40 and a knob 41. The slide plate 40 has a substantially plate shape, and is provided in the attachment/detachment portion 32 so as to be movable in the left-right direction in the second hole 38 . The knob 41 is a projection that projects upward from the top surface of the slide plate. The opening area of the second hole 38 can be adjusted by grasping the knob and moving it left and right.

In this way, by adjusting the opening area of the second hole of the attachment/detachment part, the amount of air flowing into the storage member can be adjusted, and the sterilization time can be adjusted. When it is desired to quickly sterilize small items inside the bag, the sterilization time can be shortened by narrowing the opening area of the second hole and increasing the amount of air flowing into the bag.

The air purification device according to the present invention is useful as an air purification device used for home use, office use, etc.
