FIELD: wet and dry vacuum cleaner using water and washing solution spraying processes followed by sucking thereof in conjunction with foreign particles which are then separated by means of dust catching apparatus.
SUBSTANCE: dust catching apparatus has dust catching reservoir adapted for catching of water and foreign particles according to cyclone-type catcher and equipped with suction channel formed in such a manner that air is directed along internal peripheral surface of dust catching zone defined therein. Apparatus is equipped with reservoir closing part adapted for selective restricting of dust catching zone and provided with first discharge channel. Float guiding member has inner space communicating with first discharge channel, which is opened or closed by means of float. Plurality of communication apertures are provided along outer peripheral surface of float guiding member. Dust catching filter surrounds peripheral surface of float guiding member in order to filter out foreign particles from air directed from dust catching zone into internal space of float guiding member. Wall defining water obstacle surrounds at least a portion corresponding in its area to suction channel, in spaced relation with respect to outer peripheral surface of dust catching filter. There is dividing plate in dust catching reservoir, said plate being adapted for preventing water from flowing into space outer with respect to dust catching reservoir. Wet and dry vacuum cleaner is provided with main casing incorporating power unit for creating suction force and washing solution feeding part. Dust catching reservoir is mounted within main casing and adapted for separating water and foreign particles from air sucked through nozzle unit and for catching of separated water and foreign particles. Float provided within dust catching reservoir serves for selective closing of communication between dust catching reservoir and power unit.
EFFECT: enhanced reliability in catching of water and foreign particles and more reliable placement of parts provided within water reservoir.
