Definitions
- a combined floor polisher and suction cleaner comprising, in combination, a housing with a rotary brush therein and a suction means within the housing adjacent the brush.
- a flexible floor contacting skirt depends from the entire periphery of the housing and has therein a plurality of openings through which large pieces of litter may be drawn.
- This invention relates to combined floor polishers and cleaners.
- a combined floor polisher and suction cleaner comprises, in combination; motor-driven rotatable bufling means mounted within an enveloping housing which terminates in a depending floor-contacting flexible skirt, said housing being connected to motor-driven suction means in turn connected to refuse-collecting means, said flexible skirt being adapted to maintain contact with a floor to be cleaned, despite variations in the angular disposition of said housing with respect to said floor whilst transversed across said floor.
- FIG. 1 shows, in side elevation, a general view of a combined floor polisher and suction cleaner constructed in accordance with the invention
- FIG. 2 shows, in plan view from above, the apparatus of FIG. 1,
- FIG. 3 shows, in elevation, a section along the line 33 of FIG. 2,
- FIG. 4 shows in plan, and partly in section, a view along the line 44 of FIG. 1, and
- FIG. 5 shows in elevation, and partly in section, a view along the line 55 of FIG. 2.
- a skirt 1 which may be constructed from leather or other suitable flexible material, is so formed that it provides a relatively good seal with respect to the floor, so that when the housing 2 is partly evacuated by suction means there is an inward flow of air at high velocity from the part of the floor immediately surrounding the lip 3 of the skirt and into said housing, so as to carry with it any surrounding litter such as dust.
- the seal must not, of course, be too effective because this would prevent any air input to said housing.
- the area of the gap between the lip of the skirt and the floor is preset to give a useful volumetric efficiency for the suction system as a whole. This may be achieved, for example, by scalloping or otherwise shaping the lower edge of the lip of the skirt.
- a motor (enclosed within the casing 4) which drives the suction means is, in the interests of simplicity, rigidity mounted with respect to the housing 2, and said suction means (the inlet part of which is shown generally in FIG. 5) communicates with the region beneath the flexible skirt by means of a suitable flexible tube 5 which may, for example, be not only capable of bending but also be telescopic by virtue of the provision of radial ribs therein in known manner.
- a separate motor may be provided for the butfing means, adapted to rotate a floor-contacting buff such as 6, so that both said motors may be specifically designed for their own particular purpose.
- the motor which drives the suction means should run at a much higher speed than that for the buffing means, and so the necessity for attaching a single motor to one or both of said means via reduction gearing is obviated.
- suitable transmission means is provided between said motor and the respective buffing and suction means.
- the tube 5 is not formed .from stiff material but comprises a flexible skin which commu nicates with a cheek or inner housing or plenum chamber 7 set to one side of the flexible skirt 1.
- This skin may be supported by a relatively stiff wire or frame 8 whichmay, for example, be coiled and mounted inside the skin so as to stand free from it, but is preferably located outside the skin as shown in FIG. 5, or woven into it so to prevent it from collapsing.
- the skirt 1 may comprise a main flexible portion composed of leather or similar material and the floor contacting lip 3 may be composed of nylon or similar material of a consistency suflicient to resist wear which may result from contact with a floor surface.
- the upper margin of the skirt 1 is attached to the periphery of the housing 2 in such a manner that the cushion 9 is located within a loop of the skirt material thereby preventing damage to said skirt when the outer surface of the latter makes any contact with a wall or the like during operation of the cleaner.
- the tube 5 may also be composed of flexible material, such as suede leather, and is provided with a floor con tacting lip 10 of material similar to that used in the lip 3.
- the lip 10 tends to be urged downwardly at all times into contact with the floor by means of the spring 8, even if the suction means as a whole does not possess suflicient weight to ensure this result.
- the lip 3 and/or lip may be scalloped or similarly shaped along the margins thereof to assist in the passage of larger pieces of refuse into the region beneath the skirt 1, and also ultimately into the suction means, without interfering substantially with the desirably high velocity of air admitted beneath the lips 3 and 10.
- inlet slots such as 11 may be provided in the lip 3 and similar slots such as 12 in the lip 10.
- said slots are directed as shown in FIGS. 1, 4, and 5, so that incoming material, upon hitting the buff 6 or similar rotatable member, has no direct radial path out through said slots on the rebound.
- the slots 11 and 12 must not be so large that they interfere with the high velocity input of air which it is an object of the invention to provide.
- suitable means remotely operable by the user of the cleaner may be provided so that at least one edge of said skirt may be lifted temporarily and then dropped again after such articles have been admitted.
- a combined polisher and suction cleaner constructed in accordance with the invention, is capable of removing even large litter from any hard flooring surface at the rate of less than four minutes per thousand square feet. Furthermore, it has been found capable of drawing even light dust towards the system throughout its operation, instead of spreading said dust as is the case with conventional dustmg.
- the polishing and cleaning combination may be a scrubbing and polishing device.
- a relatively stifl bristle brush 13 should be installed instead of the buff 6, and also that a suitable inlet valve should be provided for the pump of the suction means so that the latter may be cut otf.
- the pump and its associated apparatus is constructed from suitable corrosion-resistant materials, and also if the refuse-collecting means is removed; any washing water or other liquid picked up during the scrubbing operation may be allowed to pass through the pump.
- a settling trap may be provided between the fan of said pump (the fan being sealed from its associated driving motor) and a filter bag or the like which may be installed between said pump and said refuse-collecting means.
- the scrubbing process may initially use wet materials, such as water and detergents, but may terminate as a bufling or polishing process, depending on the nature of the brush selected, and thus a further economy in labour time is effected, since an operator may merely observe that the floor has been scrubbed to a sufficient extent, and then continue to propel the combination machine about the floor until the latter first dries and is then ultimately buffed to a desired extent.
- a combined floor polisher and suction cleaner comprising, in combination, a housing, motor-driven rotatable bufling means mounted within said housing, a floor-contacting first flexible skirt means depending from the entire periphery of said housing, motor-driven suction means mounted on said housing and connected to refuse-collecting means located within said first skirt means, said first flexible skirt means being adapted to maintain contact with a floor to be cleaned, despite variations in the angular disposition of said housing with respect to said floor while being traversed across said floor, a second floor-contacting flexible skirt means and a telescopic tube connecting said suction means to said second skirt means, and at least one of said skirt means being provided with at least one inlet slot inclined from the tangential direction of the housing periphery.
- a combined floor polisher and suction cleaner as claimed in claim 1 further comprising means to bias said second flexible skirt means into contact with the floor which is contacted by said first-mentioned skirt means.
