The present invention relates to surface cleaners, and more particularly, a tank arrangement in a wet surface cleaner.
In one embodiment a surface cleaner is disclosed including a main body, a supply tank, and a recovery tank. The main body has a base that supports the surface cleaner on a surface and a center column extending upwardly from the base. The supply tank and the recovery tank are removably coupled to and supported by the base. One or both of the supply tank and the recovery tank are substantially U-shaped around the main body and encompass the center column, such that the supply tank and the recovery tank form an outer wall of an upper end of the surface cleaner, the upper end opposite the base, wherein the supply tank and the recovery tank form at least 85% of a perimeter of the upper end.
In one embodiment a surface cleaner is disclosed including a base that supports the cleaner on a surface, outwardly facing side surfaces around a perimeter of the surface cleaner, a supply tank, and a recovery tank. The supply tank is removably coupled to and supported by the base, the supply tank having upwardly extending supply tank walls disposed along the perimeter, the upwardly extending supply tank walls forming a portion of the outwardly facing side surfaces. The recovery tank is removably coupled to and supported by the base, the recovery tank having upwardly extending recovery tank walls disposed along the perimeter, the upwardly extending recovery tank walls forming a portion of the outwardly facing side surfaces. The upwardly extending supply tank walls and upwardly extending recovery tank walls together form at least 85% of the perimeter of the outwardly facing side surfaces of the cleaner.
Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced
The present disclosure relates to a surface cleaner, specifically a wet surface cleaner with a supply tank and a recovery tank that are removable from the cleaner. When the supply tank and the recovery tank are attached to the cleaner, the tanks form an outer wall of an upper end of the surface cleaner forming a large portion of the perimeter of the upper end. This tank arrangement promotes even weight distribution, increases tank capacity without increasing cleaner size, and allows identification of tank fullness from various angles, among other benefits.
The supply tank 30 is removable from the surface cleaner 10 to allow filling, cleaning, and maintenance of the supply tank 30. The supply tank 30 is movable between an in use, coupled position in which the supply tank 30 is supported by the base 14 (
In one embodiment, the surface cleaner 10 further includes a cleaning tool 20 (shown in
The outer side wall 22 forms outwardly facing side surfaces around a perimeter 34 of the surface cleaner 10. In one embodiment, the supply tank 30 and the recovery tank 40 include upwardly extending tank walls that form at least a portion of the outer side wall 22. In the illustrated embodiment, the supply tank 30 and the recovery tank 40 surround the center column 16 and form the outer side wall 22 of the surface cleaner 10. In one embodiment, the supply tank 30 and the recovery tank 40 form at least 75% of the perimeter 34 of the upper end 18. In another embodiment, the supply tank 30 and the recovery tank 40 form at least 85% of a perimeter 34 of the upper end 18. In the illustrated embodiment, the outer side wall 22 formed by the tanks is substantially continuous around the surface cleaner 10, specifically the upper end 18 of the outer wall 22 is continuous around the surface cleaner 10. In one embodiment, the supply tank 30 and the recovery tank 40 are substantially U-shaped around the main body 12 and encompass the center column 16. In this embodiment, the top portion 15 may be U-shaped or may be another shape, such as rectangular. In one embodiment, one of the supply tank 30 and the recovery tank 40 is substantially U-shaped around the main body 12 and encompasses the center column 16, while the other of the supply tank 30 and the recovery tank 40 is not substantially U-shaped, for one example having generally rectangular or other cross-sectional shape. The generally rectangular or other cross-sectional shaped tank is positioned to meet the ends of the substantially U-shaped tank to form the substantially continuous outer wall 22 of the surface cleaner. In both arrangements, the supply tank 30 and the recovery tank 40 form the outer side wall 22 of the upper end 18 of the surface cleaner.
Having the supply tank 30 and the recovery tank 40 form a substantial portion of the perimeter 34 of the upper end 18 allows the surface cleaner 10 to have increased liquid carrying capacity without increasing the overall size and weight of the surface cleaner 10. By encompassing and surrounding the center column 16, the supply tank 30 and recovery tank 40 promote even weight distribution of liquid in the surface cleaner 10. Improved weight distribution of liquid in the surface cleaner 10 allow the user to more easily move the surface cleaner 10 during and after use. Further, this tank arrangement makes the capacity appear larger to the user while still being perceived as lightweight, compact, and portable.
In one embodiment, the supply tank 30 and the recovery tank 40 are formed from a transparent or translucent material. The transparent or translucent material allows a user to more easily identify the volume in the supply tank 30 or the recovery tank 40 from a variety of viewing angles. The transparent or translucent exterior also provide an appearance of increased volume capacity.
In the embodiment illustrated in
In one embodiment, the surface cleaner 10 further comprises a handle 26 that is graspable by the user for moving the surface cleaner. In the illustrated embodiment, the handle 26 is coupled to the center column 16 and extends above the upper end 18 of the supply tank and the upper end 18 of the recovery tank. In the illustrated embodiment, the handle 26 extends between the supply tank 30 and the recovery tank 40.
In the illustrated embodiment, the supply tank 30 includes a tank handle 32 on the upper end 18. The tank handle 32 may be a bail handle. The tank handle 32 allows the user to grasp and remove the supply tank 30 with one hand. In one embodiment, the tank handle 32 is a recess graspable by the user. In one embodiment, the tank handle 32 is integral with the supply tank 30.
In the embodiment illustrated in
In the illustrated embodiment, the suction source 28 of the surface cleaner 10 is powered by a power cord 50. The power cord 50 may be stored on a cord wrap assembly coupled to the surface cleaner 10. In another embodiment, the suction source 28 of the surface cleaner 10 is powered by a battery pack.
