Cleaning openings are also round in shape, for example. According to this

In this embodiment, the blower chamber 112 additionally has an exhaust air opening 122 for

Discharge of the air from the blower chamber 112, which is arranged, for example, on a side of the blower unit 110 facing away from the supply air opening 116. For example, the air is discharged via the exhaust air opening 122 into an area surrounding the extraction device 104. According to this embodiment, the further cleaning opening is located with the further

Cover element 120, the supply air opening 116 and/or the exhaust air opening 122 on a line, that is, on a rotation axis 124 of the blower unit 110. The exhaust air opening 122 is thus to be understood only optionally as an output interface for the air flow.

According to this embodiment, the cleaning opening 117 is arranged in a housing base 126 of the blower housing 106 and, for example, in a channel section 128 of the channel 114. The cleaning opening 117 is arranged opposite the vapor opening 108. The channel section 128 extends from the

Vapor opening 108 in the direction of the cleaning opening 117. According to this

In this embodiment, the channel section 128 is also arranged transversely to the surface 102 and has a transition to a blower section 130. According to this embodiment, the blower section 130 of the channel 114 connects the channel section 128 to the air supply opening 116. For example, the blower section 130 is arranged parallel to the surface 102. According to this embodiment, the further cleaning opening 119 is also arranged in the housing base 126, here in the area of the blower section 130.

According to this embodiment, the housing base 126 is formed as a common housing base 126 in which the cleaning openings 117, 119 are formed and covered by the cover elements 118, 120. The cleaning openings 117, 119 extend only over partial sections of the housing base 126.
