The injection case 200 can move left and right according to the rotation direction of the motor 233, so that steam can be sprayed onto the front of the opening 23. Accordingly, high-temperature steam can be uniformly sprayed on the front surface of the wet mop 4 provided to face the opening 23, thereby increasing the effect of sterilizing/cleaning the wet mop 4.

Let's take a closer look at the process of sterilizing/cleaning the wet mop 4 of the vacuum cleaner 2 as the spray case 200 moves.

First, the injection case 200 can be moved left and right by rotation of the moving device 230 according to the driving of the motor 233. When the spray case 200 moves left and right, the brush 201 may contact the wet mop 4 of the vacuum cleaner 2. Therefore, foreign substances attached to the mop 4 of the vacuum cleaner 2 can be effectively shaken off. Foreign substances removed from the wet mop (4) may be contained in the waste water tank (240). At this time, the steam injection hole 204 of the injection case 200 may not spray steam.

When foreign matter is contained in the wastewater tank 240, the suction device 100 may be driven. The suction device 100 can generate negative pressure to generate suction force on the dust suction port 121 side of the dust duct 120 provided to face the wastewater container 240. Foreign substances contained in the sump tank 240 may be sucked from the sump tank 240 into the dust inlet 121 by the suction force of the dust inlet 121.

After foreign substances are removed from the wet mop 4 through the above process, steam may be sprayed from the steam spray hole 204 of the spray case 200. Even when steam is sprayed, the spray case 200 can move left and right. Since the spray case 200 moves left and right, high-temperature steam can be sprayed uniformly on all areas of the wet mop 4 facing the opening 23. The wet mop 4 can be sterilized/cleaned by high temperature steam.

When high-temperature steam sterilizes/cleans the wet mop 4, the steam sprayed on the wet mop 4 may condense and fall in the form of water droplets. If the steam condenses and falls, it may be contained in the waste water tank 240. Condensed steam contained in the waste tank 240 can be easily removed by attaching and detaching the waste water tank 240.

The steam injected from the steam injection hole 404 can change its travel direction to spread left and right due to the V shape of the steam guide 402. The steam whose direction has changed can be discharged to the outside through a plurality of steam outlets 403 and come into contact with the wet mop 4. Accordingly, the steam can come into contact with the wet mop 4 at an angle, making it possible to sterilize/clean a larger area of the wet mop 4.

In the above, specific embodiments are shown and described. However, it is not limited to the above-described embodiments, and those skilled in the art can make various changes without departing from the gist of the technical idea of the invention as set forth in the claims below. .
