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. However, when vacuuming liquid material or continuously vacuuming and pumping liquid material, 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.
- US-A-6 112 366 discloses a vacuum cleaner having a motor driving an air impeller for creating suction and a pump which draws liquid material from the bottom of a tank and expels it from the tank, a mesh collection bag filtering large particulates out of the material being drawn into the vacuum cleaner.

Description
- 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. However, when vacuuming liquid material or continuously vacuuming and pumping liquid material, 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.

US-A-6 112 366 discloses a vacuum cleaner having a motor driving an air impeller for creating suction and a pump which draws liquid material from the bottom of a tank and expels it from the tank, a mesh collection bag filtering large particulates out of the material being drawn into the vacuum cleaner. -
-
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. - Referring initially to
FIGS. 1 and2 , avacuum cleaner 10 in accordance with the teachings of the present disclosure is generally shown. Thevacuum cleaner 10 includes atank 12 and an upper vacuum assembly, indicated generally at 14. Thetank 12 further includescasters 13 that may be used to move thetank 12 on a surface. In a first example of the present disclosure, liquid material is filtered prior to being drawn into thetank 12, to then be pumped out of thetank 12. In a second example of the present disclosure, liquid material is drawn into thetank 12 and is filtered when being pumped out of thetank 12. - The
upper vacuum assembly 14 includes alid 22 releasably attached to thetank 12. Attached to the lid are acover 20, a motor housing 24, and a baffle 25. Amotor 23 is disposed inside the motor housing 24. Thelid 22 makes up the bottom of theupper vacuum assembly 14 and may carry one ormore latches 23 for attaching theupper vacuum assembly 14 to thetank 12. The motor housing 24 is disposed between thelid 22 and thecover 20. When a user wishes to connect theupper vacuum assembly 14 to thetank 12, the user lifts theupper vacuum assembly 14 above thetank 12, aligns thelatches 23 with latch recesses (not shown) formed in the tank, lowers theupper vacuum assembly 14 until thelid 22 rests on top of thetank 12, and then, fastens the latches to thetank 12. Ahandle 28 is provided on the upper vacuum assembly for facilitating transportation of the assembledvacuum cleaner 10. Disposed in theupper vacuum assembly 14, among other things, are anair impeller 33 and apump impeller 35. Themotor 23 drives both theair impeller 33 and thepump impeller 35. Thetank 12 includes aninlet 40 and anoutlet 42, which are both in fluid communication with the tank. One of ordinary skill in the art will appreciate that theinlet 40 can be disposed either on thetank 12 or on theupper vacuum assembly 14. Similarly, the outlet can be disposed either on thetank 12 or on theupper vacuum assembly 14. Theair impeller 33 creates a low pressure in the tank when driven by themotor 23. The low pressure creates suction at theinlet 40 to draw liquid material into thetank 12. Thepump impeller 35 ejects liquid material out of thetank 12 through theoutlet 42 when operating by themotor 23. - Referring to
FIG. 1 , the first example of thevacuum cleaner 10 in accordance with the teachings of the present disclosure is shown. Thevacuum cleaner 10 includes aninlet hose 50 having aninlet end 52 and anozzle end 54. Theinlet end 52 is removably connected to theinlet 40, and acleaning tool 55 removably connects to thenozzle end 54. Thevacuum cleaner 10 also includes anoutlet hose 56 having an outlet end 58 and adisposal end 60. The outlet end 58 of theoutlet hose 56 removably connects to theoutlet 42. Afilter housing 70 is disposed in the flow path of theinlet hose 50. Accordingly, theinlet hose 50 includes two sections--a firstinlet hose section 72 that fluidically connects theinlet 40 to afilter housing outlet 74, and a secondinlet hose section 76 that fluidically connects thecleaning tool 55 to afilter housing inlet 78. Thus, during the operation of thevacuum cleaner 10, liquid material flows through thecleaning tool 56 and the secondinlet hose section 76 before entering thefilter housing 70 from thefilter housing inlet 78. The liquid material then flows out thefilter housing 70, through the firstinlet hose section 72, to be deposited into thetank 12 from theinlet 40. - Referring to
FIG. 3 , thefilter housing 70 includes afilter housing lid 80 and afilter 82 that removes debris from the liquid material. One or ordinary skill in the art will appreciate the numerous possible filter types and configurations that are well known in the art for removing debris from liquid material. In the disclosed examples, thefilter 82 includes a mesh material (shown inFIG. 3 ) disposed in the flow path between thefilter housing inlet 78 and thefilter housing outlet 74 to intercept any debris that may be in the liquid material. One of ordinary skill in the art will appreciate that the smaller the mesh density of thefilter 82, the smaller the size of particles thefilter 82 can intercept. However, afilter 82 that has a very fine mesh can impede the flow of liquid material from thefilter housing inlet 78 to thefilter housing outlet 74. Conversely, afilter 82 that has a very coarse mesh will only intercept very large debris and allow smaller sized debris to pass through. Accordingly, thefilter 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 thefilter housing 70. - One of ordinary skill in the art will appreciate that the
filter 82 may be constructed from a variety of materials, including metal and plastic. However, the mesh material of thefilter 82 is preferably constructed from a plastic material to prevent corrosion thereof as a result of continuous and repeated contact with liquid material. Furthermore, the mesh material of thefilter 82 is preferably constructed from a flexible plastic material to facilitate easy removal of thefilter 82 from thefilter housing 70 for cleaning. - Referring to
FIG. 2 , the second example of thevacuum cleaner 10 in accordance with the teachings of the present disclosure is shown. In this embodiment, thefilter housing 72 is disposed in the flow path of theoutlet hose 56. Accordingly, theoutlet hose 56 includes two sections--a firstoutlet hose section 84 that fluidically connects theoutlet 42 to afilter housing inlet 78, and a secondoutlet hose section 86 that fluidically connects thefilter outlet 74 to thedisposal end 60. Thus, during the operation of thevacuum cleaner 10, liquid material flows from theoutlet 42 through the firstoutlet hose section 84 before entering thefilter housing 70. The liquid material then leaves the filter housing 70 through thefilter housing outlet 74 for ejection from thedisposal end 60. - When operating the
vacuum cleaner 10, the rate at which liquid material is drawn into thetank 12 may not be equal to the rate at which the liquid material is pumped out of thetank 12. Accordingly, to provide for continuous operation of thevacuum cleaner 10, and to synchronize the in-flow of liquid material into thetank 12 with the out-flow of liquid material from the tank 12 (i.e., a one-to-one ratio), thevacuum cleaner 10 may include a metering device 90 (shown inFIG. 2 ). Themetering device 90 regulates the in-flow of liquid material into thetank 12. Accordingly, themetering device 90 can be disposed anywhere in the flow path of the liquid material prior to entering thetank 12. In the first example of thevacuum cleaner 10 shown inFIG. 1 , themetering device 90 is disposed in the filter housing 70 (shown inFig. 1 ). In the second example of thevacuum cleaner 10 shown inFIG. 2 , themetering device 90 is disposed in the flow path of theinlet hose 50. - One of ordinary skill in the art will readily appreciate that any one of the described first and second examples of the disclosed
vacuum cleaner 10 can be optionally practiced by a user. For instance, if a user chooses to operate thevacuum cleaner 10 in accordance with the first example, he can place thefilter housing 70 in the flow path of theinlet hose 50 by connecting the first and secondinlet hose sections filter housing 70. Alternately, the user can operate thevacuum cleaner 10 in accordance with the second example by placing thefilter 70 in the flow path of theoutlet hose 56 between the firstoutlet hose section 84 and the secondoutlet hose section 86. To facilitate the alternate filter house positions, releasable couplings may be provided between the first and secondinlet hose sections second hose sections inlet hose sections outlet hose sections - 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, ahead 57 of thecleaning tool 55 is preferably flexible to conform to the contour of the surface to be cleaned. Furthermore, thecleaning 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, thecleaning tool 55 can include a scrubbingbrush 59. - When cleaning the bottom surface of a pond or a swimming pool, 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 theinlet hose 50. If thefilter housing 70 is attached to theinlet hose 50 in accordance with the first example of the present disclosure, the debris is removed from the water prior to reaching thetank 12. The filtered water is then pumped out of thetank 12 and back into the pond or swimming pool through theoutlet hose 56. If thefilter housing 70 is attached to theoutlet hose 56 in accordance with the second example of the present disclosure, the debris and water are deposited into thetank 12. Prior to being ejected from thedisposal end 60 of theoutlet hose 56, the debris is removed from the water by thefilter 82. A user can also remove debris that is floating in the water in a pond or swimming pool by simply placing thenozzle end 54 of the inlet hose 50 (if nocleaning tool 56 is attached, or thecleaning tool 56 if it is attached to the nozzle end 54) near the debris to draw the debris and the surrounding water into theinlet hose 50. As shown inFIG. 3 , the user can at anytime or when necessary clean thefilter 82 by opening thelid 80 of the filter housing to either remove the debris from thefilter housing 70, or take thefilter 82 out of thefilter housing 70 to clean. - One of ordinary skill in the art will readily appreciate that the
inlet hose sections outlet hose 56 or theoutlet hose sections filter housing 70, and the metering device (not shown) can be used with any self-evacuating tank-type vacuum cleaner, as long as theinlet hose 50 and theoutlet hose 56 are sized to provide removable connection to the vacuum cleaner's inlet and outlet, respectively. Accordingly, any tank-type self-evacuating vacuum cleaner can be modified to provide the function of pond or swimming pool cleaning. - Although certain apparatus constructed in accordance with the teachings of the invention have been described herein, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all embodiments of the teachings of the invention fairly falling within the scope of the appended claims either literally or under the doctrine of equivalents.
