Cleaning Apparatus

The present disclosure generally relates to surface cleaning devices and more specifically to wet/dry cleaners.

Surface cleaning apparatuses are configured to clean one or more surfaces within an environment (e.g., a floor). An example surface cleaning apparatus includes a wet/dry cleaner. A wet/dry cleaner is configured to apply at least one liquid (e.g., water) to a surface to be cleaned and to recover at least a portion of the applied liquid from the surface to be cleaned. At least a portion of any debris (e.g., liquid debris or solid debris) on the surface to be cleaned becomes entrained within the applied liquid such that debris laden liquid (or dirty liquid) can be collected within the wet/dry cleaner for later disposal.

The present disclosure is generally directed to a wet/dry cleaner. The wet/dry cleaner includes a supply tank, a recovery tank, and a cleaning tool fluidly coupled to the supply tank and the recovery tank via a flexible conduit. During a cleaning operation, the cleaning tool is configured to apply cleaning fluid (e.g., water) from the supply tank onto a surface to be cleaned (e.g., a floor) and recover at least a portion of the delivered cleaning fluid from the surface to be cleaned to be stored in the recovery tank for later disposal. The supply tank includes a tool cleaner configured to clean the cleaning tool after completion of the cleaning operation.

shows a schematic example of a wet/dry cleaner. As shown, the wet/dry cleanerincludes a supply tank, a recovery tank, a cleaning tool, and a tool cleaner. The cleaning toolis configured to deliver cleaning fluid (e.g., water and/or water combined with a cleaning chemical) from the supply tankto a surface to be cleaned(e.g., a floor) and to recover at least a portion of the delivered cleaning fluid from the surface to be cleaned. The recovered cleaning fluid is deposited within the recovery tankfor later disposal by a user.

The wet/dry cleanermay further include a flexible conduithaving a supply lineand a recovery line. The supply linefluidly couples the supply tankto the cleaning tooland the recovery linefluidly couples the recovery tankto the cleaning tool. In other words, the flexible conduitmay generally be described as being configured to fluidly couple the cleaning toolto the supply tankand the recovery tank. During a cleaning operation, a fluid pumpurges cleaning fluid from the supply tankthrough the supply lineand to the cleaning toolfor delivery to the surface to be cleaned. A suction motorurges air and delivered cleaning fluid into the cleaning tooland along the recovery lineto be deposited in the recovery tank. During the cleaning operation, debris may become adhered to the cleaning tooland/or the recovery line.

The tool cleaneris configured to cooperate with the cleaning toolto remove at least a portion of any debris adhered to the cleaning tooland/or the recovery line. The tool cleaneris fluidly coupled to the supply tankvia a cleanout line, the cleanout linebeing separate from the supply line. During a cleanout operation, the cleaning toolis positioned (e.g., by a user) onto the tool cleanersuch that the recovery lineis fluidly coupled with the cleanout line. When the suction motoris activated, cleaning fluid is drawn from the supply tankalong the cleanout lineinto the cleaning toolalong the recovery lineand into the recovery tank. As cleaning fluid is drawn from the supply tank, at least a portion of any debris adhered to the cleaning tooland/or the recovery linemay be removed therefrom and deposited in the recovery tank. In other words, the tool cleanermay be generally described as being configured to cooperate with the cleaning toolto draw cleaning fluid from the supply tankand into the cleaning toolto remove at least a portion of any debris adhered to the cleaning tooland/or the recovery line. Such a configuration may mitigate (e.g., prevent) generation of odors within the cleaning tooland/or the recovery line.

The wet/dry cleanermay include one or more sensorscommunicatively coupled to a controller. The one or more sensorsmay include a fluid level detection sensor for the supply tankand/or the recovery tank, a turbidity sensor within the recovery line, and/or any other type of sensor. For example, when the one or more sensorsinclude a turbidity sensor, the turbidity sensor may be positioned at outlet of the recovery lineand be configured to detect a turbidity of cleaning fluid passing into the recovery tank. In this example, the turbidity sensor may be configured to measure the turbidity of recovered cleaning fluid during the cleanout operation. The controllermay use the output of the turbidity sensor to generate a cleanout operation complete indication on a user interface. In some instances, the one or more sensorsmay include a cleaning tool presence sensor configured to detect an engagement (e.g., direct or indirect) of the cleaning toolwith the tool cleaner. For example, in response to detecting engagement, the controllermay cause the suction motorto activate to begin the cleanout operation. Additionally, or alternatively, a user may manually activate the suction motorto begin the cleanout operation.

shows a schematic example of an upright extraction cleaner. The upright extraction cleaneris an example of the wet/dry cleanerof. As shown, the upright extraction cleanerincludes a surface cleaning head, an upright sectionpivotally coupled to the surface cleaning head, and the cleaning tool. The upright sectionis configured to pivot between an above floor cleaning position (e.g., an upright position) and a floor cleaning position (e.g., a reclined position). The upright sectionmay be configured to be selectively retained in the above floor cleaning position (e.g., using an upright lock).

As shown, the upright sectionmay include the supply tank, the recovery tank, and the tool cleaner. For example, the tool cleanermay be coupled to the supply tank. By way of further example, the tool cleanermay be coupled to the surface cleaning head. As discussed in relation to, the tool cleaneris configured to cooperate with the cleaning toolfor the purposes of at least partially cleaning the cleaning tooland/or the recovery line.

As also shown, the surface cleaning headmay include one or more wheelsconfigured to moveably support the upright extraction cleaneron a surface to be cleaned(e.g., a floor), a forward suction inlet, and an agitator chamberdisposed between the one or more wheelsand the forward suction inlet. The agitator chamberincludes an agitatorrotatably disposed therein. The agitator chambermay or may not be configured to be exposed to suction (e.g., the agitator chambermay be selectively exposed to suction using a valve).

The flexible conduitmay be configured to removably couple to one or more of the surface cleaning headand/or the upright section. For example, the upright sectionmay include a coupling portconfigured to fluidly couple each of the supply lineand the recovery lineof the flexible conduitto the supply tankand the recovery tank, respectively. When the flexible conduitis coupled to the surface cleaning headand/or the upright section, transitioning the upright sectionto the above floor cleaning position from the floor cleaning position may fluidly couple each of the supply lineand the recovery lineof the flexible conduitto the supply tankand the recovery tank, respectively. When the flexible conduitis coupled to the surface cleaning headand/or the upright section, transitioning the upright sectionto the floor cleaning position from the above floor cleaning position may fluidly decouple each of the supply lineand the recovery lineof the flexible conduitfrom the supply tankand the recovery tank, respectively.

shows a schematic example of a handheld extraction cleaner, which is another example of the wet/dry cleanerof. As shown, the handheld extraction cleanerincludes a main body, a handleextending from the main bodythat is configured to support the main bodyin a user's hand, and the tool cleaner. The main bodyincludes a supply receptacleand a recovery receptacle. The supply receptacleis configured to receive the supply tankand the recovery receptacleis configured to receive the recovery tank. The supply tankmay be removably received within the supply receptacle(e.g., for purposes of refilling) and the recovery tankmay be removably received within the recovery receptacle(e.g., for purposes of emptying). As shown, the handlecan extend between the supply receptacleand the recovery receptacle.

The flexible conduitis configured to couple with the main bodysuch that the supply linefluidly couples with the supply tankand the recovery linefluidly couples with the recovery tank. The main bodyand the handleare configured such that when a user grasps the handlewith one hand, the supply tankand the recovery tankare moved collectively with the main body. Such a configuration allows a user to grasp the cleaning toolin a first hand while carrying the main bodyin a second hand.

As shown, the tool cleanermay be provided with the supply tank. However, the tool cleanermay be provided at other locations, for example, with the main body. As discussed in relation to, the tool cleaneris configured to cooperate with the cleaning toolfor the purposes of at least partially cleaning the cleaning tooland/or the recovery line.

One or more sidewallsconnect the top sideand the bottom side. The tool cleanerincludes a tool platformincluding one or more fluid aperturesthrough which cleaning fluid within the supply tank bodycan flow (e.g., when the one or more fluid aperturesare exposed to suction).

shows a top perspective view of the supply tankand a cleaning toolconfigured to cooperate with the tool cleaner. The cleaning toolis an example of the cleaning toolof.

As shown, the cleaning toolincludes a tool bodyhaving a tool suction inlet, a fluid dispenser, and a tool agitator. The tool agitatoris disposed between the fluid dispenserand the tool suction inletrelative to a body longitudinal axisof the tool body. As shown, the tool suction inlethas a tool inlet maximum width.

At least one of the tool agitator, the first accessory agitator, and/or the second accessory agitatormay have different characteristics from at least one other of the tool agitator, the first accessory agitator, and/or the second accessory agitator. For example, the tool agitatormay include bristles(e.g., in the form of tufts), the first accessory agitatormay include one or more curved wipers, and the second accessory agitatormay include one or more agitation protrusions(e.g., flexible protrusions).

As shown, the one or more fluid aperturesinclude a plurality of fluid aperturesforming a central group of apertures, a first lateral group of aperturesarranged at one side of the central group of apertures, and a second lateral group of aperturesarranged at another (e.g., opposing) side of the central group of apertures.

As such, when the cleaning toolis moved into engagement with the tool cleaner, the tool suction inletextends over and encloses each of the fluid aperturesforming the central group of apertures. Such a configuration allows cleaning fluid to be suctioned through the central group of aperturesand into the cleaning toolvia the tool suction inlet.

shows a cross-sectional perspective view of the supply tanktaken along the line VI-VI of. As shown, the supply tank bodyincludes a fluid cavityconfigured to receive the cleaning fluid. The fluid cavityis fluidly coupled to the valved fluid outletand the tool cleaner. The valved fluid outletis configured to selectively fluidly couple the fluid cavityto the fluid dispenser() such that cleaning fluid within the fluid cavitycan be delivered to the fluid dispenser. In other words, the valved fluid outletmay generally be described as forming a portion of a supply line(e.g., a beginning portion). The supply lineis an example of the supply lineof.

As shown, the tool cleanerincludes a fluid channelfluidly coupled to the one or more fluid aperturesand a tank ductfluidly coupling the fluid channelto the fluid cavity. In other words, the one or more fluid aperturesmay generally be described as being fluidly coupled to the tank ductvia the fluid channelsuch that the one or more fluid aperturesare fluidly coupled to the fluid cavity. The fluid channelis disposed between the tool platformand a portion of the supply tank body. In some instances, the tool platformmay define at least a portion of at least one sidewall of the fluid channel. At least a portion of the tank ductextends into the fluid cavitysuch that at least a portion of the tank ductextends between the bottom sideand the top sideof the supply tank body. For example, the tank ductmay extend into the fluid cavitysuch that a distal endof the tank ductis positioned closer to the bottom sidethan to the top sideof the supply tank body.

The fluid channeland the tank ductare configured such that, when the one or more fluid aperturesare exposed to suction, cleaning fluid within the fluid cavityis drawn into the tank ductand the fluid channeland passes through at least one of the one or more fluid apertures. As such, the fluid channeland the tank ductmay generally be described as forming at least a portion of a cleanout line. The cleanout lineis an example of the cleanout lineof.

The tool cleanermay further include a tool cleaner valve. The tool cleaner valveis configured to selectively transition between an open state and a closed state. When in an open state, cleaning fluid is capable of freely passing through the tool cleaner valve. When in the closed state, cleaning fluid is substantially prevented from passing through the tool cleaner valve(e.g., at least 90%, at least 95%, at least 97%, at least 99%, or 100% of cleaning fluid is prevented from passing through the tool cleaner valve). When in the open state, cleaning fluid is capable of freely entering the tank duct(e.g., in the presence of suction), passing through the fluid channel, and exiting the tool cleanervia at least one of the one or more fluid apertures. In some instances, the tool cleaner valveis biased (e.g., using a spring) towards the closed position and configured such that, when one of the cleaning tool(), the first cleaning accessory(), or the second cleaning accessory() is positioned on the tool cleaner, the tool cleaner valveis transitioned towards the open position.

The tank ductmay include a flexible material or may be rigid. When the tank ductincludes a flexible material (e.g., a silicone material), at least a portion of the tank ductmay noticeably deform (e.g., experience at least a 5%, at least a 10%, at least a 15%, at least a 20%, at least a 40%, at least a 50%, or at least a 75% change in shape relative to a non-deformed resting state) when exposed to a force substantially equal to or greater than its own weight. When the flexible material is included, at least a portion of the tank ductmay be buoyant such that the distal endis spaced apart from the bottom sideof the supply tank bodyas a result of the buoyancy. For example,shows an example of a tank ductincluding a flexible material and a buoyant bodycoupled to the tank duct. Inclusion of a flexible material in the tank ductmay also discourage residual cleaning fluid from entering the tank ductwhen the supply tankis upended for purposes of refilling via a refill openingenclosed by the removable refill cap.

When the tank ductis rigid, the distal endmay be spaced apart from the bottom sidesuch that cleaning fluid is able to enter the tank duct. Alternatively, the distal endmay be in contact with the bottom sideand the tank ductmay include fluid inlets at the distal end through cleaning fluid may enter the tank duct.

shows a magnified perspective view generally corresponding to region VII of. As shown, the tool platformincludes a valve actuatorcoupled to the tool cleaner valve. The valve actuatorincludes an actuation platformand an actuator bodyextending from the actuation platform. The actuator bodyincludes a coupling endconfigured to couple to the tool cleaner valve. For example, the coupling endmay be configured to be received within a coupling cavityof the tool cleaner valve(e.g., to form a press-fit with the tool cleaner valve, to be coupled via a fastener, to form an adhesive coupling, and/or any other form of coupling).

In operation, application of a force on the actuation platformcauses the tool cleaner valveto disengage from a channel inletof the fluid channel. The tool cleaner valvemay include a sealwhich moves out of engagement with a portion of the channel inletin response to the application of the force on the actuation platform. For example, the actuation platformmay be caused to move in response to a force exerted when the cleaning tool, with or without one of the first or second cleaning accessoryorcoupled to the tool body, comes into engagement (e.g., directly or indirectly) with the tool platform. When the tool cleaner valvedisengages with the channel inlet, the fluid channelis fluidly coupled with the fluid cavitysuch that cleaning fluid can be drawn through the tank ductand into the fluid channelin the presence of suction.

In operation, when the force is removed from the actuation platform, the springurges the tool cleaner valvetowards the closed position. The springextends between at least a portion of the actuation platformand at least a portion of the tank duct. For example, a first endof the springmay engage (e.g., directly or indirectly engage) with a portion of the actuation platformand a second endof the springmay engage (e.g., directly or indirectly engage) with a portion of the fluid channel(e.g., an inner surfaceof the fluid channel). In some instances, the springmay extend around the channel inletsuch that at least a portion of the springis exposed to cleaning fluid passing through the tool cleaner valve.

As shown, the channel inletmay be disposed within the tank duct. For example, an inner surfaceof the tank ductmay be configured to form a snap fit connectionwith the fluid channel. However, other configurations are possible.

The fluid channelmay be configured to encourage a flow of air and cleaning fluid therethrough such that cleaning fluid is caused to exit from at least one of the one or more fluid apertures. For example, the fluid channelcan include a flared regionthat transitions to planar regionsand. A channel heightof the fluid channelmay decrease as the flared regiontransitions into the planar regions.

A substantial portion (e.g., at least 75%, at least 80%, at least 90%, at least 95%, at least 99%, or at least 100%) of the planar regionsandmay be disposed below a respective one of the first and second lateral groups of aperturesand. One or more of the fluid aperturesof the central group of aperturesmay be included with the actuation platform. In other words, the valve actuatormay generally be described as including one or more of the fluid aperturesof the central group of apertures. In some instances, the central group of aperturesmay be included within an alignment protrusionextending from the actuation platform. The alignment protrusionis configured to be received within the tool suction inlet(). The receipt of the alignment protrusionwithin the tool suction inletmay encourage the alignment of the tool suction inletwith the central group of apertures.

For example, the cleaner openingmay be configured to receive at least a portion of the tank duct. The cleaner openingmay be configured to be sealingly engaged with a portion of an outer surfaceof the tank duct. The supply tank bodymay include one or more retainers(e.g., molded therein) for coupling (e.g., removably or non-removably) the tool cleanerto the supply tank body.

A tank handlemay be pivotally coupled to the supply tank body. The tank handleincludes pivot armsand a grasping portionextending between the pivot arms. The pivot armsare pivotally coupled to the supply tank body. The cleaner openingcan be disposed between the pivot arms. As such, when the tool cleaneris coupled to the supply tank body, the tool cleanermay be disposed between the pivot arms.

In some instances, the tool cleanermay further include a connection latch. The connection latchmay be configured to removably couple the supply tankwith a cleaner (e.g., the wet/dry cleanerof, the upright extraction cleanerofand/or the handheld extraction cleanerof). The connection latchmay include a biased detentconfigured to cooperate with a corresponding retainer. For example,shows a perspective view of a handheld extraction cleaner bodyhaving a retainerconfigured to cooperate with the connection latchto selectively retain the supply tankon the handheld extraction cleaner body.

Returning to, the one or more tool alignment wallsmay include a retention slot. The retention slotis configured to slidably receive a portion of the actuation platform. The retention slotmay be configured to guide the movement of the actuation platformin response to application of a force thereon.
