Abstract (en)
A cyclone separation device includes a swirl chamber (29) for swirling a dust-containing air along the sidewall therein to separate dust from the dust-containing air, and a dust collection chamber communicating with the inside of the swirl chamber (29). The dust collection chamber is configured to be able to be in a collection state for collecting the dust separated by the swirl chamber and in a disposal state for disposing of the collected dust. The inner wall surface of the dust collection chamber is in a first state when the dust collection chamber is in the collection state, and become in a second state when the dust collection chamber become in the disposal state. A property of the inner wall surface of the dust collection chamber in the first state to the dust is different from a property of the inner wall surface of the dust collection chamber in the second state to the dust.
