Abstract (en)
[origin: EP0702924A2] To establish in the vacuum cleaner reservoir of a vacuum cleaner a wet sprinkling process to take away from ambient air and /or from air sucked up at least the dust, such reservoir is provided with a chain of components comprised by:a removable tubular appendix (2) ; a bag-like multitask filter (101); a multitask flanged drum (5), whose upper flange (55) provides a "u" cross- sectioned water tight channel.and whose bottom flange (5') includes a number of sprinkling passages (100); an annular droplet wall or dam (6); a four-legged spacer or support (12); a filter (8) made by mineral imputrescible fibres; and a water pool . The optimum of the members of the chain may be determined by the formula: <MATH> wherein Q = Fluid flow; D= Degree of drop distribution T= Water transfer; u0= Optimal wetting (of the filter) ue= Actual wetting (of the filter) <IMAGE>
