Description
- The present invention relates to a cleaning apparatus, and more specifically to an apparatus which finds particular usefulness in cleaning carpet, upholstery, draperies and the like, and which further has a novel electrical control which allows the cleaning apparatus to have several modes of operation which increases the usefulness of the present invention.
- The prior art is replete with various types of cleaning devices, and other machines which have various types of liquid heating assemblies for heating a cleaning fluid, and which is subsequently sprayed onto an object to be cleaned, and then suctioned back into a recovery tank. An example of such a prior art device is found in U.S. Pat. No. 7,171,721, the teachings of which are incorporated by reference herein. The device exemplified by the aforementioned patent utilizes a catalytic heater for heating fluid which is then sprayed onto a surface which is to be cleaned and which is subsequently suctioned back into a recovery tank.
- The device as taught in U.S. Pat. No. 7,171,721 was conceived and reduced to practice to address perceived problems in the prior art devices utilized heretofore. Chief among the problems encountered with the prior art devices related to the fact that the these devices were not designed so as to deliver effective amounts of heated cleaning solution to a surface which needed to be cleaned. As noted in the teachings of U.S. Pat. No. 7,171,721, because electrical outlets capable of delivering more than 1,800 watts of electricity are relatively uncommon in residential and commercial buildings in North America, compromises in the temperature, and reduced fluid flow rates must necessarily be made in cleaning apparatus which are electrically powered because an adequate amount of electrical power is usually not available to do the desired level work.
- The device as exemplified in the teachings of U.S. Pat. No. 7,171,721 attempted to address the problems related to the prior art as discussed, above, by utilizing a catalytic heater which was employed to heat the cleaning solution in a fashion such that the resulting heated cleaning solution could effectively clean soiled surfaces in a manner that was not possible, heretofore.
- While the invention as exemplified in the aforementioned U.S. patent has worked with various degrees of success, the problems relating to the fabrication of a cleaning apparatus for use with carpet, draperies and the like remain. Other problems attendant with such prior art devices have included concerns which relate to the size of such machines, and their ability to be used in interior rooms where the amount of space available for the machine to be maneuvered around or pass between furniture and other objects is quite limited. A new and novel cleaning apparatus is disclosed, and which avoids the detriments associated with the individual prior art references and teachings employed heretofore, and further provides a means of cleaning soiled surfaces in a highly efficient, and expeditious manner by employing a single source of electrical power which is typically available in both commercial buildings and residential structures.
- A first aspect of the present invention relates to a cleaning apparatus which includes a chassis for enclosing an electrically energizable vacuum motor; a fluid pump; and first and second electrical heaters, and which, when individually energized, consume a given amount of electricity; and an electrical control coupled in controlling relation relative to the respective vacuum motor; fluid pump and first and second electrical heaters, and wherein the electrical control has a first, second and third mode of operation, and wherein during the respective modes of operation the respective vacuum motor; fluid pump and first and second electrical heaters are selectively energized in a predetermined manner such that the cleaning apparatus consumes less than about 20 amps of electrical power.
- Another aspect of the present invention relates to a cleaning apparatus which includes a chassis which has a sidewall which defines, at least in part, a cleaning solution tank, and which further defines an internal equipment cavity; a source of a cleaning solution which is received within the cleaning solution tank; a recovery tank having an internal cavity, and which communicates with the ambient environment, and which is, further, releasably coupled to the chassis; an electrically energized vacuum motor which is mounted within the internal equipment cavity of the chassis, and which is further coupled in predetermined, selective, fluid flowing relation relative to the internal cavity of the recovery tank, and wherein the vacuum motor, when energized, can remove ambient air from the internal cavity of the recovery tank, and then discharge the ambient air back to the ambient environment so as to create a partial vacuum within the internal cavity of the recovery tank; a first and second heater which are electrically energized, and which are further individually mounted in the internal equipment cavity of the chassis, and wherein the respective heaters are further each coupled in fluid flowing relation relative to the source of cleaning solution, and wherein the first and second heaters may be selectively energized so as to impart heat energy to a portion of the cleaning solution; an electrically energized fluid pump mounted within the internal equipment cavity of the chassis, and which is further coupled in fluid receiving relation relative to the source of the cleaning solution, and the respective first and second heaters, and wherein the fluid pump, when energized, discharges the cleaning fluid, under pressure, and further delivers the cleaning solution to a surface which is to be cleaned; and an electrical control which is coupled with, and operable to selectively energize the vacuum motor; fluid pump; and first and second heaters, and wherein the vacuum motor; fluid pump; and first and second heaters, when energized, individually utilize a given amount of electrical power, and wherein the electrical control selectively energizes the respective vacuum motor; fluid pump and first and second heaters in a fashion so as to restrict a cumulative amount of electrical power consumed by the cleaning apparatus to less than about 20 amps during operation.

- A cleaning apparatus which embodies the teachings of the present invention is generally indicated by the
numeral 10 inFIG. 1 following. - As will be seen from a study of
FIG. 1 , for example, the present invention is operable to be selectively moved across a supporting surface, here indicated by thenumeral 11. As depicted hereinafter, theapparatus 10 is employed to clean theunderlying surface 11, over which it moves. The surface could be a solid surface, or further it may be covered with carpeting or other similar covering. Further the present invention could be used to clean draperies and the like. As will be appreciated, theseunderlying surfaces 11 may become soiled through the traffic which is moving across same or become soiled by accumulating dust which is in the air. Thecleaning apparatus 10 further includes a plurality of earth or surface engaging wheels orcastors 12, of conventional design, and which allow the cleaning apparatus to be moved in various directions relative to theunderlying surface 11, the castors allow the apparatus to be easily maneuvered in tight spaces, such as the interior areas of rooms in commercial or residential buildings, not shown. The surface engaging wheels orcastors 12 are secured to amovable chassis 13 as seen. Thechassis 13 includes abottom surface 14, which defineswheel wells 15, which receive, and otherwise secure the respective earth engaging wheels orcastors 12 therein. When secured in thewheel wells 15, the respective earth-engaging or surface-engaging wheels 12 position thebottom surface 14 in spaced relation relative to the surface to be cleaned 11. - The
cleaning apparatus 10, and more specifically thechassis 13 thereof, is defined by an exterior facing sidewall, which is generally indicated by thenumeral 20. As depicted in the drawings, the exterior sidewall is corrugated in its exterior surface texture. This shape provides greater strength for thesidewall 20. Additionally, thechassis 13 has afirst end 21, and an oppositesecond end 22. Still further, theexterior sidewall 20 has a top peripheral edge which is generally indicated by thenumeral 23. Additionally, and as seen by reference toFIG. 6 , thechassis 13 includes aninterior sidewall 24, which is spaced from theexterior sidewall 20 in order to provide a gap therebetween, and which forms, in that gap, a cleaning solution tank. The aforementioned cleaning solution tank will be discussed in greater detail, hereinafter. Additionally, and as will be seen in the drawings, theinterior sidewall 24 defines an internal equipment cavity which is generally indicated by thenumeral 25, and which further receives and encloses a number of operational components, which will be discussed in greater detail in the paragraphs which follow. - The
chassis 13, and more specifically, the exterior andinterior sidewalls numeral 30. The cleaning solution tank, as seen inFIG. 6 , is defined, in part, by afilling aperture 31, which allows a user, not shown, to supply a source ofcleaning solution 32 into thecleaning solution tank 30, and which may then be dispensed, selectively, to the surface to be cleaned 11. The present invention further includes a fluid coupler which is generally indicated by thenumeral 33, and which extends substantially normally, outwardly, relative to thesecond end 22 of thechassis 13. Thefluid coupler 33 is operable to deliver the source of thecleaning solution 32, to the distal end of a cleaning appliance or wand, as will be discussed in greater detail hereinafter. In the drawings as provided, various internal fluid conduits are removed to aid in an understanding of the invention. Acontrol panel 34 is mounted on thefirst end 21 of thechassis 13. Thecontrol panel 34 includes a number of electrical switches which are described, below. In particular, the control panel includes an on/offpower control switch 35; andelectrical switches respective switches apparatus 10. The first mode of operation may be selected or implemented by turning on or activating the firstelectrical switch 36. Further, the second mode ofoperation 37 may be implemented or selected by pushing or activating the secondelectrical switch 37. Further, the third mode of operation may be implemented by depressing or activating the thirdelectrical switch 38. Thecontrol panel 34 is arranged such that only one mode of operation may be utilized at a time while the invention operates. The respective modes of operation will be discussed in greater detail, below. - As seen in the drawings, the
apparatus 10 is coupled to a source of electrical power which is generally indicated by the numeral 40. The source ofelectrical power 40, as seen inFIG. 9 , is a commercially available source and which is typically supplied to most residential homes and commercial structures, that being, less than about 20 amps. One of the chief advantages of thepresent invention 10 relates to the fact that the present invention can be operated and used with electrical power sources which are normally supplied to commercial and residential homes, and further the present apparatus uses only a single electrical power cord. Some prior art devices have employed two or more power cords which were attached to different 20 amp electrical circuits or sources of power in order to provide sufficient electrical power for energizing the previously used cleaning devices. - The
present invention 10 includes an electrically energizable vacuum motor which is generally indicated by the numeral 50, and which is further positioned or mounted within theinternal equipment cavity 25, as earlier noted. The electrically energizable vacuum motor is of traditional design, and has atop surface 51, which has anair intake aperture 52 which is formed therein. The electrically energizable vacuum motor is arranged so as to be releasably coupled in selective fluid flowing relation relative to the internal cavity of a recovery tank, as will be described, hereinafter. The vacuum motor, when energized, is effective in removing ambient air from an internal cavity of the recovery tank, and then discharge the ambient air back to the ambient environment so as to create a partial vacuum within the internal cavity of the recovery tank, as will be disclosed. Additionally, and enclosed within theinternal equipment cavity 25, are several heaters, which are generally indicated by the numeral 60. The heaters include afirst heater 61, and asecond heater 62. The individual heaters are mounted in fluid receiving relation relative to the source of thecleaning solution 32, and which is enclosed within thecleaning solution tank 30. Each of therespective heaters 60 may be selectively energized. In any case, the heaters, as provided, each consume only about 750 watts worth of electrical power when energized. The heaters, as provided, are selectively energized in a fashion consistent with the operation of theelectrical panel 34, during the first, second and third modes of operation, and which are individually implemented when theelectrical switches - The
cleaning apparatus 10 of the present invention further includes a selectively, and electrically energizablefluid pump 70, which is located within theinternal equipment cavity 25, and which is further coupled in fluid withdrawing relation relative to thecleaning solution tank 30, and which is further oriented in fluid delivering relation relative to the first andsecond heaters fluid coupler 33, which is mounted on thechassis 13. Again, the electrically energizedfluid pump 70 is selectively energized based upon the signal, activation, or energizing as provided by thecontrol panel 34, when thecleaning apparatus 10 is operated in the first, second and third modes, as will be discussed below. Mounted in a location which is in covering relation relative to thevacuum motor 50, is a vacuum well that is generally indicated by the numeral 80. The vacuum well 80 has amain body 81, which has atop surface 82, and anopposite bottom surface 83. Thebottom surface 83 is positioned in juxtaposed relation relative to thetop surface 51 of the electrically energizablevacuum motor 50. As seen in the drawings, the vacuum well 80 is further defined by a downwardly dependingsidewall 84. Further, anaperture 85 is formed substantially centrally of thetop surface 82, and is disposed in substantial coaxially alignment relative to theaperture 52, which is formed or defined by thetop surface 51 of the electrically energizablevacuum motor 50. The vacuum well, and more specifically the sidewall thereof, directs any previously usedcleaning solution 32, which may have escaped from a recovery tank, to move downwardly and away from theaperture 85, which is defined by thetop surface 82 of the vacuum well 80 so as to prevent thevacuum motor 50 from receiving or ingesting any cleaning solution which may cause subsequent damage to thevacuum motor 50. This structure, and the function, as described above, will become more apparent following a thorough consideration of the paragraphs which follow. - The
present cleaning apparatus 10 includes arecovery tank 100, which is operable to receive used, or previously expended cleaning fluid orsolution 32, which has been earlier dispensed and applied to the underlying soiledsurface 11, which is to be cleaned. As noted earlier, the source of cleaningsolution 32 is provided by way of the electrically energizedfluid pump 70, once the cleaningsolution 32 has been selectively supplied to therespective heaters 60, and which have been selectively energized in the fashion, as will be described, below. In this regard, therecovery tank 100 has afirst end 101, and an oppositesecond end 102, which is disposed in covering relation relative to theinternal equipment cavity 25, which is defined by thechassis 13. In addition, therecovery tank 100 has a sidewall defining aninternal cavity 103, which encloses the previously dispensed, and recovered source of cleaningsolution 32. Additionally, and as will be recognized from the drawings, therecovery tank 100 has abottom surface 104, which is disposed in juxtaposed relation relative to thetop surface 82, of the vacuum well 80, and which is further positioned in overlying relation relative to the electrically energizablevacuum motor 50. As should be understood, and as best seen by reference toFIG. 8 , thebottom surface 104 has anaperture 105 formed therein. Theaperture 105 is operable to be coaxially aligned relative to theapertures vacuum motor 50 is energized, it is operable to withdraw ambient air which is located within theinternal cavity 103 of therecovery tank 100. When this event occurs, a partial vacuum is created in same. Once the partial vacuum is created, ambient air from the surrounding environment is operable to be received within theinternal cavity 103 by passing through thehose coupler 111. This movement of the exterior, surroundingambient air 103 into theinternal cavity 103 is operable to suction up and then transmit the previously dispensedcleaning solution 32 from the surface to be cleaned 11, into theinternal cavity 103, and through the features which will be described in greater detail in this paragraph. Therecovery tank 100 has aconvenient handle 110 which is mounted on thefirst end 101, and which allows therecovery tank 100 to be removed from its rested and secured relationship on thechassis 13, and allows the user thereof to dispose of any recovered cleaning solution received within therecovery tank 100. Additionally, and as seen in the drawings, the recovery tank includes a ball valve assembly ormember 112, which is received within theinternal cavity 103 of therecovery tank 100. The ball valve is of well known design, having a cane-shapedvalve member 113, and further having amoveable ball member 114 which is received within thevalve member 113. As should be understood, once a given amount of recovered cleaningfluid 32 is received within theinternal cavity 103, the recovered cleaning fluid or solution may then rise to a level or depth where it forces theball member 113 to move within theball valve 114 so as to prevent any further vacuum from being imparted or created in theinternal cavity 103 of therecovery tank 100. Once this event occurs, no further recovery of cleaningfluid 32 can take place. Therecovery tank 100 is releasably affixed to thechassis 13 by means of the respectivereleasable locking members 115, which are operable to engage thechassis 13 which is positioned, therebelow. As will be recognized, thepresent cleaning apparatus 10 is operably coupled to acleaning wand 120 of traditional design. The cleaning wand has aspray head 121, which is mounted at its distal end. Further thespray head 121 is coupled by means of afluid conduit 122 to afluid dispensing control 123. Thecontrol 123 is utilized by the operator of thedevice 10. A flexible hose, 125, couples thefluid dispensing control 123 to thefluid coupler 33, which is mounted on thechassis 13. Anotherflexible hose 124 couples the cleaningwand 120 to thehose coupler 111. By operating thecontrol 123, the operator can release a given amount of cleaningsolution 32 onto the underlying, soiled supportingsurface 11, and thereafter the cleaningwand 120 can suction the cleaning solution up and then deliver the usedcleaning solution 32 to thehose 124, and which is coupled to thehose coupler 111, which is made integral with therecovery tank 100. Thehose coupler 111 couples or otherwise allows the ambient environment to communicate with theinternal cavity 103 of therecovery tank 100. - As earlier discussed with regards to the
control panel 34, thepresent invention 10 includes first, second and third modes of operation, which are controlled or implemented by thecontrol panel 34, and by means of thepower switch 35, and the first, second andthird switches present invention 10 is designed so as to allow thepresent cleaning apparatus 10 to only implement one mode of operation at a time. The respective modes of operation are arranged in such a fashion that the present cleaning apparatus does not consume or otherwise utilize more than 20 amps of electrical power during any mode of operation. Therefore, the present invention provides a convenient means whereby theapparatus 10 can be utilized in either commercial or residential structures and will not need any special electrical circuits for rendering the apparatus operational. - In the first mode of operation, and when the first
electrical switch 36 is energized, following the supplying ofelectrical power 40 to theapparatus 10, by first depressing or activatingswitch 35, the present invention is operable to provide a heated sprayer operation, that is, during the first mode of operation the first and secondelectrical heaters vacuum motor 50 remains in a de-energized state, and the electrically energizablepump 70 is rendered operational. During the first mode of operation, the first and second heaters, which utilize less than 750 watts each, are operable to heat thecleaning solution 32 as provided, to a given high temperature, and then deliver the heated solution to thespray head 121 by way of thepump 70 in order to apply it directly to a particularly soiled region of the supportingsurface 11. - In the second mode of operation, one of the two
heaters vacuum motor 50, and theliquid pump 70 are both energized. In the second mode of operation, the heated cleaning fluid orsolution 32 may be delivered to a soiled region ofsurface 11. However, during the second mode of operation thevacuum motor 50 renders thecleaning apparatus 10 operational so as to allow thecleaning wand 120 to recover or suction-up the previously dispensed cleaningfluid 32 from the supportingsurface 11, and then deliver it into therecovery tank 100. Still further, and in the third mode of operation, only thevacuum motor 50, and theliquid delivery pump 70 are energized. In the third mode of operation, thecleaning solution 32 may be delivered to a soiled region of the supportingsurface 11, and then it may be vacuumed, or otherwise removed from the supportingsurface 11 by thevacuum motor 50, and the subsequently returned to therecovery tank 100, in the manner as previously disclosed. - Therefore, it will be seen that this presently disclosed cleaning
apparatus 10 provides multiple cleaning functions in a manner not possible heretofore. As noted above, thepresent cleaning apparatus 10 is operable to consume less than about 20 amps of electrical power, and may further operate on a single electrical conduit or extension cord in a manner to provide multiple functions which allows a user to clean variously soiledunderlying surfaces 11 in a highly efficient, and expeditious manner. - The operation of the described embodiment of the present invention is believed to be readily apparent and is briefly summarized at this point.

In the arrangement as seen in the drawings, a source of cleaningsolution 32 is enclosed within thecleaning solution tank 30, and which is further supplied or coupled to the first andsecond heaters fluid pump 70. Thecleaning apparatus 10 includes arecovery tank 100, which is releasably borne by thechassis 13, and which further defines aninternal cavity 103. Theinternal cavity 103 of therecovery tank 100 is coupled in fluid flowing relation relative to both a surrounding ambient environment, and thevacuum motor 50. In the arrangement as seen in the drawings, a singleelectrical power cord 41 for electrically coupling thecleaning apparatus 10 to a source ofelectricity 40, and for energizing thevacuum motor 50 andfluid pump 70, and first and secondelectrical heater electrical control 34 implements the first, second and third modes ofoperation - As earlier discussed, and in the first mode of operation, the
electrical control 34 energizes theliquid pump 70, and the first and secondelectrical heaters temperature cleaning solution 32, which may be sprayed upon a soiledsurface 11, which needs to be cleaned. In the second mode of operation, which is implemented by means of the secondelectrical switch 37, theelectrical control 34 energizes thevacuum motor 50,liquid pump 70, and one of the first or secondelectrical heaters heated cleaning solution 32 having a temperature which is less than that which is provided byapparatus 10 during the first mode of operation, and which is applied to a soiledsurface 11, that needs to be cleaned. The energizedvacuum motor 50 is effective in removing the previously supplied, and now usedcleaning solution 32, from the soiledsurface 11, and then depositing the usedcleaning solution 32 into therecovery tank 100. In the third mode of operation, theelectrical control 34 energizes thevacuum motor 50 and theliquid pump 70 so as to provide anunheated cleaning solution 32, which is then applied to a soiledsurface 11, and which must be cleaned. The energizedvacuum motor 50 is effective in removing the previously applied and now usedcleaning solution 32 from the soiledsurface 11, and then depositing the usedcleaning solution 32 into therecovery tank 100. As earlier noted, the first andsecond heater electrical power 40. As earlier noted in the application, therecovery tank 100 is releasably mounted on thechassis 13 and located above, and in covering relation relative to therespective vacuum motor 50,liquid pump 70, and the first andsecond heaters recovery tank 100 has a sidewall and which defines aninternal cavity 103, and abottom surface 104, which is coupled to the sidewall. Thebottom surface 104 has anaperture 105 formed therein. Therecovery tank 100 further includes aball valve 112, which is coupled in fluid metering or controlling relation relative to theaperture 105, which is formed in thebottom surface 104 of the recovery tank, and which is further oriented within theinternal cavity 103 of therecovery tank 100. - The present invention includes a vacuum well 80, which is mounted above the
vacuum motor 50, and which is further releasably, and fluid sealedly cooperates with thevacuum motor 50. The vacuum well 80 has atop surface 82, and which defines anaperture 85, which is disposed in substantially coaxial alignment with theaperture 105, which is formed in thebottom surface 104 of therecovery tank 100. The vacuum well 80 is defined, at least in part, by a downwardly dependingsidewall 84. Thesidewall 84 directs any previously usedcleaning solution 32, which escapes from therecovery tank 100 to move downwardly, and away from, theaperture 52, and which is defined by thetop surface 82 of the vacuum well 80, so as to prevent thevacuum motor 50 from receiving or ingesting anycleaning solution 32, which may subsequently cause damage to thevacuum motor 50. - Therefore, it will be seen that the
present cleaning apparatus 10 provides a convenient means whereby a soiled, underlying supporting surface covered by carpeting or the like can be cleaned in a manner not possible, heretofore. The present invention provides multiple modes of operation, which allows soiled surfaces of various types to be treated in different manners, and provides flexibility and assorted options for individuals to clean supporting surfaces in a manner not possible heretofore, and by utilizing existing electrical power sources, which are typically available in commercial and residential structures. - In compliance with the statute, the invention has been described in language more or less specific as to structural and methodical features.
