Definitions

  • This disclosure relates generally to vacuum cleaners, and more particularly, to a self-evacuating vacuum cleaner for cleaning ponds or swimming pools.
  • Tank-type self-evacuating vacuum cleaners typically have the capability to vacuum debris and liquid material into a holding tank, and pump liquid material out of the holding tank.
  • Such vacuum cleaners have a filter to prevent the collected debris from entering the motor assembly. If the vacuum cleaner is used to collect dry debris, such as dust, a user can open the tank and empty the collected dust out of the tank.
  • the debris that is flowing with the liquid material or floating therein will be sucked into the holding tank with the liquid material and pumped out of the tank with the liquid material. Thus, the debris that is in the liquid material is not collected to effectively filter the liquid material.
  • FIG. 1 is a vacuum cleaner in accordance with a first example of the teachings of the instant disclosure.
  • FIG. 2 is a vacuum cleaner in accordance with a second example of the teachings of the instant disclosure.
  • FIG. 3 is an exploded view of a filter housing in accordance with the teachings of the instant disclosure.

  • a filter 82 that removes debris from the liquid material.
  • the filter 82 includes a mesh material (shown in FIG. 3) disposed in the flow path between the filter housing inlet 78 and the filter housing outlet 74 to intercept any debris that may be in the liquid material.
  • the mesh density of the filter 82 the smaller the size of particles the filter 82 can intercept.
  • a filter 82 that has a very fine mesh can impede the flow of liquid material from the filter housing inlet 78 to the filter housing outlet 74 .
  • a filter 82 that has a very coarse mesh will only intercept very large debris and allow smaller sized debris to pass through.
  • the filter 82 can include a mesh material from a range of mesh densities to provide desired filtering of the debris from the liquid material without impeding the flow of liquid material through the filter housing 70 .
  • the filter 82 may be constructed from a variety of materials, including metal and plastic.
  • the mesh material of the filter 82 is preferably constructed from a plastic material to prevent corrosion thereof as a result of continuous and repeated contact with liquid material.
  • the mesh material of the filter 82 is preferably constructed from a flexible plastic material to facilitate easy removal of the filter 82 from the filter housing 70 for cleaning.
  • the filter housing 72 is disposed in the flow path of the outlet hose 56 .
  • the outlet hose 56 includes two sections—a first outlet hose section 84 that fluidically connects the outlet 42 to a filter housing inlet 78 , and a second outlet hose section 86 that fluidically connects the filter outlet 74 to the disposal end 60 .

  • inlet hose sections 72 and 76 can be identical to the outlet hose sections 84 and 86 . Accordingly, a user can simply use these hose sections interchangeably to easily and optionally practice the above-described first and second examples.
  • the cleaning tool 55 can be one of many vacuum cleaning tools that are well known to those of ordinary skill in the art. However, to clean contoured surfaces of ponds or swimming pools, a head 57 of the cleaning tool 55 is preferably flexible to conform to the contour of the surface to be cleaned. Furthermore, the cleaning tool 55 can be constructed in a non-linear shape, such as a curved shape, to closely match the contour of the surface to be cleaned. As is well known to those of ordinary skill in the art, the bottom surfaces of ponds or swimming pools need to be cleaned occasionally to remove a variety of debris and deposits therefrom. To dislodge such debris, the cleaning tool 55 can include a scrubbing brush 59 .
  • a user can dislodge debris from the bottom surface by scrubbing the cleaning tool 55 on the bottom surface.
  • the dislodged debris and the surrounding water are then drawn into the inlet hose 50 .
