초록 ▼

A vacuum system which uses water as a filtration medium to effectively capture dirt and dust particles. The vacuum system uses a canister or tank, which can be placed on a wheeled mobile frame for mobility. Within the tank, a removeable insert includes a number of equally spaced annular plates with a first of the annular plates fitting snugly against the outside wall of the tank and the next plate fitting snugly against the outside wall of a central cylindrical column. The plates then continue to alternate from outside wall of the tank to the outside wall of the column to form alternating gaps and, thus, a serpentine airflow path. The bottom portion of the tank is filled with a quantity of water sufficient to cover the bottom of an air intake port. A blower draws air, along with accompanying debris, from the intake port through the water. The water filtered air, which now contains a considerable quantity of entrained water, is then drawn through the serpentine path wherein the resulting varying air speeds, along with the eddy currents generated by this path, effectively remove the entrained water from the air.

A vacuum cleaner comprising: (a) blower means for drawing a vacuum; (b) air intake means; (c) debris collection means flow connected with said air intake means and said blower means comprising: (i) cylindrical tank means having an output port flow connected to said blower means and an intake port flow connected to said air intake means, said tank means including a water basin wherein said intake means is submerged under water within said water basin such that substantially all intake air is directed through said water and a substantial portion of any accompanying debris is captured by said water, said tank means further including an axially aligned central column sealably joined with a bottom of said tank means and surrounded by said water basin; and (ii) flow control means positionable within said tank means above said water basin, said flow control means directing airflow from the surface of said water through a serpentine path toward said output port whereby water entrained in said airflow is substantially removed therefrom, said flow control means comprising insert means adapted to be removably placed within said tank means, said insert means comprising a series of generally parallel annular plates positioned about said central column and spaced longitudinally along said tank means; said plates comprising first and second plates, the first plate having an outer diameter slightly smaller than the inside diameter of said tank means so as to snugly fit thereagainst and an inside diameter substantially larger than the outside diameter of said central column to leave a first gap therebetween; and the second plate having an inside diameter slightly larger than the outside diameter of said central column so as to snugly fit thereagainst and an outside diameter substantially smaller than the inside diameter of said tank means to leave a second gap therebetween; said plates being vertically spaced and arranged on said insert such that the first and second plates alternate along the longitudinal axis of said tank means such that said first and second gaps and the spacing between said plates forms said serpentine path.
