[0012] refer to Figures 1 to 17 Reference numeral 10 generally designates a cleaning device 10, which includes a supply tank 12 configured to hold cleaning fluid and a fluid or liquid delivery system 14 in fluid communication with the supply tank 12 for dispensing the cleaning fluid to the surface to be cleaned. The cleaning device 10 also includes a recovery system 16 for capturing and collecting stains or debris, such as liquids and / or solids, from the surface being cleaned. A suction source 18 is configured to create a vacuum effect along an airflow path 20 through the cleaning device 10. A suction port 22 is in fluid communication with the suction source 18. A recovery tank assembly 24 is disposed along the airflow path 20 between the suction port 22 and the suction source 18. The recovery tank assembly 24 includes a fluid inlet 26 and a fluid outlet 28 downstream of the fluid inlet 26. The recovery tank assembly 24 also includes a liquid collection area 30 for collecting liquids and a solid collection area 32 for collecting solids. Liquids and solids are captured by the suction port 22 using the vacuum effect and carried along the airflow path 20 to the recovery tank assembly 24 for collection and subsequent disposal.

[0013] The recovery tank assembly 24 is configured to separate or sort liquid and solid materials into separate collection areas 30, 32. The recovery tank assembly 24 includes a separator 34, typically configured as a lower surface or base plate 34, which at least partially defines a sorting chamber or channel 36 between a fluid inlet 26 and a fluid outlet 28. At least a portion 38 of the base plate 34 is liquid- or fluid-permeable, and the liquid collection area 30 is typically positioned below the fluid-permeable portion 38 of the base plate 34 along an airflow path 20. The solid collection area 32 is positioned between the fluid inlet 26 and the fluid outlet 28 along the airflow path 20. Liquid is configured to be guided by working air into the sorting channel 36 and then through the fluid-permeable portion 38 of the base plate 34 to be collected in the liquid collection area 30. Solid materials are configured to be guided by working air into the sorting channel 36 and into the solid collection area 32.

[0014] like Figure 1As shown, the recovery system 16 disclosed herein is configured to separately store or retain collected liquid and solid materials during the cleaning process. The recovery system 16 can also be considered a wet / dry sorting recovery system 16 or a dual-zone recovery system 16. Separation of liquid and solid materials improves the cleaning function of the cleaning equipment 10 by reducing or preventing the formation and hardening of mixtures in a single collection space when liquid and solid debris are mixed. Furthermore, reducing or preventing such mixing improves the user experience by allowing for easier disposal of captured liquid and solid materials. Additionally, this sorting improves the separation of liquid and solid debris from the working air before the working air flows along the airflow path 20 to / through the suction source 18. The recovery system 16 can collect liquid and solid materials separately from the cleaned surface, and / or collect liquid and solid materials simultaneously. Solid materials may be referred to as “dry” materials, but solid materials may also include wet solid clumps (e.g., grains in milk). The recycling system 16 can sort liquids into the liquid collection area 30 and solids into the solid collection area 32 when collecting liquids alone, collecting solids alone, or collecting a combination of liquids and solids simultaneously.

[0015] Normally, the sorting of liquids and solids is performed sequentially. In this case, the liquid is separated from the working air first, followed by the solids. This recovery system 16 differs from systems where the recovered material flows through a filter and the filter captures solid debris. In a configuration where the filter captures solid debris, the liquid must flow through the captured solid debris to reach the liquid collection space; therefore, over time, the system may become clogged and cease operation. In this recovery system 16, the liquid is separated first, and the solids are captured elsewhere, so the captured solids do not substantially impede the collection and recovery of the liquid.

[0016] Cleaning device 10 may be a suction cleaner commonly used for cleaning mats, carpets, curtains, and upholstered surfaces. Cleaning device 10 typically includes a fluid delivery and recovery system having a liquid delivery system 14 and a recovery system 16. Cleaning device 10 includes a liquid delivery system 14 for dispensing cleaning fluid for one or more cleaning processes. The liquid delivery system 14 includes a supply tank 12 for holding and storing at least one cleaning fluid. The cleaning fluid may be water, one or more cleaning formulations, or a combination thereof. Many household suction cleaning tasks can be performed by washing the surface to be cleaned with water and / or by using cleaning formulations containing surfactants, stabilizers, fragrances, and / or other active and inactive ingredients.

[0017] The liquid delivery system 14 typically includes a pump 50, valves, and / or similar features to direct liquid from the supply tank 12 out of the cleaning device 10 via a dispensing or spraying outlet 52. The cleaning device 10 may optionally include a heater 54 to heat or warm the dispensed cleaning fluid. Depending on the configuration of the cleaning device 10, the spraying outlet 52 may be part of the housing 60 (see [link to relevant documentation]). Figure 2A ), part of attachment or tool 62 (see Figure 2B ), and / or a portion of the spray bar 64 used for engaging tool 62 (see Figure 2B ).

[0018] The recovery system 16 is configured to draw fluids (including air and liquids) and other debris (including solid matter) into the cleaning device 10. The recovery system 16 includes a suction source 18 to create a suction or vacuum effect at a nozzle or inlet 22, thereby drawing liquids and / or solid matter from the surface being cleaned. The suction source 18 may be a motorized fan assembly. In some aspects, the suction source 18 may be a motor and impeller assembly, wherein the motor is configured to drive the impeller assembly.

[0019] The recovery system 16 also includes a recovery tank assembly 24 disposed along the airflow between the inlet 22 and the suction source 18 for holding material collected during the cleaning process for subsequent disposal. Typically, the suction source 18 is configured to generate a working airflow along an airflow path 20, which typically carries liquid and solid material. In other words, the cleaning device 10 is configured to draw working air containing liquid and debris into the recovery tank assembly 24 through the inlet 22. The recovery tank assembly 24 is configured to sort the carried material into a liquid collection area 30 or a solid collection area 32. The working air is configured to flow through the recovery tank assembly 24, thereby facilitating the separation process, and is discharged from the cleaning device 10 through the suction source 18. Depending on the configuration of the cleaning device 10, the inlet 22 may be part of the housing 60 (see [link to relevant documentation]). Figure 2A ) and / or a part of accessory or tool 62 (see Figure 2B ).

[0020] Still referencing Figure 1 At least the pump 50, suction source 18, and heater 54 are components of the cleaning device 10, which are electrically connected to a power source 68, such as a battery or a power cord plugged into a household power outlet. A user can selectively close a power switch 70 between the power source 68 and the electrical components of the cleaning device 10 to activate the electrical components. The power source 68 can be used to power the cleaning device 10 and / or its connected components (such as tool 62 and its components [see...]). Figure 2B ))powered by.

[0021] Now for reference Figures 1 to 2BThe dual-zone sorting and recycling system 16 can be included in various cleaning devices 10. For example, such as... Figure 2A As shown, the cleaning device 10 can be configured as an upright cleaning device 10. The upright cleaning device 10 includes a housing 60, which may include legs or a base 76 and an upright support 78 with an elongated handle 80. A user can move and manipulate the upright cleaning device 10 using the elongated handle 80, typically by rolling wheels 82 on the underlying surface. Typically, the upright cleaning device 10 has a drive assembly that facilitates user manipulation. The upright cleaning device 10 is typically large and heavy, with a surface near the wheels 82 that engages with the underlying base plate 34, such as via a suction port 22 and / or an agitator.

[0022] like Figure 2B As shown, the cleaning device 10 can be a portable cleaning device 10, which is generally smaller and lighter than the upright configuration for easy carrying by the user. The portable cleaning device 10 includes a housing 60, which typically includes a lower outer shell 90 defining seats 92, 94 for receiving and supporting the supply tank 12 and the recycling tank assembly 24. In the illustrated configuration, a central support 96 of the housing 60 extends from the lower outer shell 90 to be positioned between the seats 92, 94 when mounted on the housing 60, and thus between the supply tank 12 and the recycling tank assembly 24. The central support 96 typically includes a handle 98 for carrying the portable cleaning device 10.

[0023] Portable cleaning device 10, such as Figure 2B The configuration shown typically includes a tool 62, which is connected to the housing 60 via an accessory hose 100 and a spray bar 64. The tool 62 allows the suction inlet 22 and / or spray outlet 52 to be manually operated by a user relative to the cleaning device 10 and along the surface being cleaned. The tool 62 is configured to utilize various features and functions of the cleaning device 10, such as one or both of the liquid delivery system 14 and the recovery system 16, when the tool 62 is connected to the cleaning device 10. The spray bar 64, which connects the tool 62 to the accessory hose 100, may include a trigger 102 for releasing / spraying liquid from the liquid delivery system 14 via the spray outlet 52. The recovery system 16 may create a vacuum effect at the suction inlet 22 of the tool 62 to draw liquid and solid materials into the recovery tank assembly 24 and ultimately into the corresponding collection areas 30, 32. The tool 62 may also be used with… Figure 2A The upright cleaning device 10 shown is used together.

[0024] Now for reference Figures 1 to 3The recovery tank assembly 24 includes a fluid inlet 26 for receiving working air containing liquid and debris trapped at the suction inlet 22. The working air is configured to flow through the recovery tank assembly 24 along an airflow path 20. As the working air flows through the recovery tank assembly 24, it is configured to sort liquids carried by the working air into a liquid collection area 30, sort solids carried by the working air into a solids collection area 32, or sort both liquids and solids into their respective collection areas 30 and 32. The recovery system 16 includes a separate liquid collection area 30 and a solids collection area 32 along the airflow path 20 and between the fluid inlet 26 and the fluid outlet 28 of the recovery tank assembly 24.

[0025] refer to Figure 4 and Figure 5 The sorting channel 36 extends between the fluid inlet 26 and the fluid outlet 28. The configuration of the sorting channel 36 and the components defining it can facilitate or aid in the separation of liquid and solid substances from the working air into the corresponding collection areas 30, 32. For example, the sorting channel 36 may be generally circular, curved, or define one or more bends or bends. In this respect, the sorting channel 36 can typically be or define a "U", "C", "J", "L", etc. Bends or bends can facilitate the separation of liquid along the sorting channel 36 from branches of the airflow path 20 by guiding the liquid downwards for collection, rather than guiding it around bends and bends. Furthermore, the sorting channel 36 is typically a horizontal channel that utilizes vacuum effects and / or gravity to vertically guide airflow, liquid, and / or solid substances into the collection areas 30, 32.

[0026] Alternatively, the height, diameter, or size of the sorting channel 36 may vary between the fluid inlet 26 and the fluid outlet 28 to facilitate the sorting of material into the corresponding collection areas 30, 32. For example, the fluid inlet 26 and the receiving end or proximal end 110 of the sorting channel 36 adjacent to the fluid inlet 26 may have a first larger size. This size may be larger than the size or diameter of the inlet conduit 112 disposed upstream of the fluid inlet 26 for directing air to the fluid inlet 26. The increased size from the inlet conduit 112 to the proximal end 110 of the fluid inlet 26 and the sorting channel 36 results in a slower airflow velocity as working air enters the sorting channel 36. The slower airflow facilitates the guidance of liquid into the liquid collection area 30. As the sorting channel 36 extends toward the distal end 114 adjacent to the fluid outlet 28, the size or diameter of the sorting channel 36 narrows or decreases. The narrowed sorting channel 36 results in an increased airflow velocity, which can help carry solid material into the solid collection area 32. The size of the sorting channel 36 may depend on the size of the fluid inlet 26 (see [reference]). Figure 6The cover portion 116 forming the sorting channel 36 is inclined or angled toward the base plate 34 (see...). Figure 7 and Figure 9 ), and / or base plate 34 defines an inclined or angled surface (see Figures 13 to 17 ).

[0027] Furthermore, the configuration of the base plate 34 can facilitate the sorting of liquid and solid materials into separate collection areas 30, 32. At least a portion 38 of the base plate 34 near the fluid inlet 26 is fluid-permeable. The base plate 34 may define orifices, openings, slots, etc., or be constructed of a fluid-permeable material. The base plate 34 may include or be any element, material, or combination thereof that allows air and liquid to flow through the fluid-permeable portion 38 while reducing or preventing solid material or solid material of a predetermined size from being guided through or across the base plate 34. Thus, solid material can be retained in the sorting channel 36 after the fluid-permeable portion 38 of the base plate 34 to continue being carried to or remaining in the solid collection area 32. The fluid-permeable portion 38 of the base plate 34 may form discrete segments of the base plate 34 aligned with the liquid collection area 30. Alternatively, the fluid-permeable portion 38 may extend beyond the liquid collection area 30 and / or extend along the entire or considerable length of the base plate 34.

[0028] Furthermore, the base plate layer 120 can be disposed above or integrated into the base plate 34. The base plate layer 120 can be a perforated layer, which can facilitate the sorting of liquid and solid materials into separate collection areas 30, 32. In some aspects, the base plate layer 120 can have smaller openings to reduce the opening of the fluid-permeable portion 38, thereby further reducing any small solid debris that may fall into the liquid collection area 32. The base plate layer 120 can be removable, which allows consumers to more easily clean the sorting channel 36. Various porous materials can be used in the base plate layer 120 to facilitate the sorting of liquid and solid debris.

[0029] refer to Figure 4 and Figure 5 The fluid inlet 26 and fluid outlet 28 of the recovery tank assembly 24 can be in fluid communication with the inlet conduit 112 and outlet conduit 118, respectively. The inlet conduit 112 and outlet conduit 118 can be components of the recovery tank assembly 24 and / or portions located within the housing 60 to form the airflow path 20. The location of the fluid inlet 26 and fluid outlet 28, and the configuration of the conduits 112, 118, can depend on the configuration of the cleaning equipment 10 and the position of the recovery tank assembly 24 relative to the housing 60 of the cleaning equipment 10. The dual-zone recovery system 16 can also have various configurations to arrange the two collection zones 30, 32, which can depend on the configuration of the cleaning equipment 10 and / or the recovery tank assembly 24.

[0030] refer to Figure 2B and Figure 3 An exemplary configuration of the recycling tank assembly 24 for the portable cleaning device 10 is shown. Figure 2B In the example shown, the housing 60 of the portable cleaning device 10 includes two seats 92, 94 on opposite sides of a central support 96. The first seat 92 is configured to receive a supply canister 12. The supply canister 12 typically includes a valve configured to engage with a receiver on the housing 60 when the supply canister 12 is in the first seat 92. This opens the valve to allow cleaning fluid in the supply canister 12 to be directed by a pump 50 to a spray outlet 52. Figure 1 The second housing 94 is configured to receive the recovery tank assembly 24. The housing 60 includes mating parts for providing fluid communication with the fluid inlet 26 and the fluid outlet 28. In some respects, conduits 112, 118 may be provided in the housing 60 to openings configured to align and mate with or extend from the fluid inlet 26 and fluid outlet 28 of the recovery tank assembly 24.

[0031] refer to Figure 3 and Figure 4 The recovery tank assembly 24 includes a recovery tank 130 having an outer tank wall 132 and a partition wall 134 to form a first chamber portion 136 defining a liquid collection area 30 and a second chamber portion 138 defining a solid collection area 32. The partition wall 134 extends between opposing sections of the outer tank wall 132 such that the chamber portions 136, 138 are arranged laterally adjacent to each other. Typically, the liquid collection area 30 in the first chamber portion 136 is located upstream of the solid collection area 32 in the second chamber portion 138. Therefore, the first chamber portion 136 is typically arranged on the same side of the recovery tank assembly 24 as the fluid inlet 26, while the second chamber portion 138 is located on the same side as the fluid outlet 28. Furthermore, in the illustrated configuration, the first chamber portion 136 is shown as larger than the second chamber portion 138 to have a higher capacity. However, the chamber portions 136 and 138 may be the same size, or the second chamber portion 138 may be larger than the first chamber portion 136, without departing from the teachings of this document.

[0032] refer to Figure 5 and Figure 6Although the recycling tank 130 includes collection areas 30, 32 for holding liquid and solid substances, most or all of the components for sorting the liquid and solid substances into the respective collection areas 30, 32 may be included in a lid or cover 148 for the recycling tank 130. The cover 148 is configured to mate with or operatively engage with the recycling tank 130 to close chamber portions 136, 138. The cover 148 includes an outer cover wall 150 configured to engage with the outer tank wall 132 of the recycling tank 130 and form the interior of the cover 148.

[0033] The cover 148 also includes an inner guide wall 152 and an outer guide wall 154, which at least partially form a sorting channel 36 in the cover 148. The guide walls 152, 154 form a portion of an airflow path 20 through the cover 148 and define the shape of the sorting channel 36. The guide walls 152, 154 extend along the outer cover wall 150 from opposite sections near the fluid inlet 26 toward the outer cover wall 150 and then toward the fluid outlet 28, forming a "J" or "U" shaped path. The outer guide wall 154 includes a side portion 156 adjacent to the outer cover wall 150 and a cover portion 116 extending toward or into the inner guide wall 152 to form the top of the sorting channel 36. An end wall 158 extends near the fluid outlet 28 between the inner guide wall 152 and the outer guide wall 154 to form an end barrier of the sorting channel 36 to help block or deflect solid material into the solid collection area 32. It is conceivable that other configurations of the cover 148 could be used, such as omitting the outer guide wall 154, so that the outer cover wall 150 serves as the outer boundary of the sorting channel 36.

[0034] The cover 148 includes a base plate 34 extending between guide walls 152, 154 to form the bottom portion of the sorting channel 36. Therefore, the sorting channel 36 is entirely composed of... Figure 5 and Figure 6 The cover 148 shown is formed. A base plate 34 extends between the fluid inlet 26 and the fluid outlet 28. More specifically, the base plate 34 extends from the fluid inlet 26 to near the end wall 158, following the “U” or “J” shape.

[0035] At least a portion 38 of the base plate 34 positioned above the liquid collection area 30 is fluid-permeable. This fluid-permeable portion 38 extends at least to the proximal end 110 of the sorting channel 36 near the fluid inlet 26. Figure 5 and Figure 6In the configuration shown, the base plate 34 is configured as a grid, with slots or openings extending parallel to the guide walls 152, 154. The slots extend along the length of the base plate 34 from the fluid inlet 26 at least above the liquid collection area 30. The section of the base plate 34 above the second chamber portion 138 may include a solid surface for filling the slots, or may have a solid structure and may not be fluid-permeable, such as... Figure 6 As shown. Although the base plate 34 is shown as a grid with slots, the base plate 34 may include any element or combination of elements that allows fluid to pass through into the liquid collection area 30 while preventing solid debris or material of a predetermined size from passing through.

[0036] The guide opening 160 is defined by the base plate 34 of the adjacent end wall 158 at the distal end 114 of the sorting channel 36. The guide opening 160 is sized sufficiently to allow solid material to fall through or be guided through it. The guide opening 160 is positioned above or in fluid communication with the second chamber portion 138 to allow solid material to be guided from the sorting channel 36 to the solid collection area 32.

[0037] Still referencing Figure 5 and Figure 6 as well as Figure 7 In addition to liquids and solids being guided through the recovery tank assembly 24, working air is also guided through the recovery tank assembly 24, thus forming the first branch of the airflow path 20 through the recovery tank assembly 24. This is achieved by the suction source 18 ( Figure 1 The vacuum effect generated can help draw in or guide liquid to liquid collection area 30, draw in or guide solid matter to solid collection area 32, and draw in or guide working air through recovery tank assembly 24. At least some of the working air is guided along with the liquid through fluid-permeable portion 38 of base plate 34. This helps guide the liquid through base plate 34. Recovery tank assembly 24 includes a separator 170 that extends into first chamber portion 136 when cover 148 is engaged with recovery tank 130. Separator 170 engages with separator wall 134 to form airflow passage 172. Inner guide wall 152 defines airflow opening 174 near fluid outlet 28 and in fluid communication with airflow passage 172. Working air flowing into first chamber portion 136 is directed toward suction source 18 ( Figure 1 The fluid is drawn through the airflow channel 172, through the airflow opening 174, and through the fluid outlet 28.

[0038] Similarly, at least some of the working air is directed through the guide opening 160 and into the second chamber portion 138, forming a second branch of the airflow path 20 through the recovery tank assembly 24. The cover 148 defines an additional airflow opening 176 on the opposite side of the end wall 158 (typically on the upper surface of the second chamber portion 138) (e.g., this can be considered part of the base plate 34). The working air flowing into the second chamber portion 138 along with solid matter is drawn through the airflow opening 176 and through the fluid outlet 28.

[0039] Filter 178 can be disposed in one or both of the airflow openings 174 and 176, or at the fluid outlet 28. Filter 178 can be any coarse or fine particle filter or filter media. Filter 178 allows working air to flow through it while reducing or preventing debris (e.g., liquid and solid matter) from flowing through the airflow openings 174 and 176. Filter 178 can reduce the amount of material flowing from the recovery tank assembly 24 to the suction source 18. Figure 1 () detrital material.

[0040] refer to Figures 8 to 10 The dimensions of the fluid inlet 26 and / or sorting channel 36 can control the speed at which working air passes through the sorting channel 36 to aid in separating liquids and carrying solid materials. In the illustrated configuration, connectors 122, 124 are coupled to the cover 148 at the fluid inlet 26 and fluid outlet 28. Connectors 122, 124 may be part of the recycling tank assembly 24 or the cleaning device 10. The inlet end 184 of the inlet connector 122 is configured to engage the inlet conduit 112. The inlet conduit 112 and the inlet end 184 of the connector have a first size or diameter. The fluid inlet 26 and / or proximal end 110 of the sorting channel 36 have a second size or diameter, which is larger than the first size (see also...). Figure 6 In some respects, the second dimension of the proximal end 110 is approximately two to four times the size of the first dimension of the inlet conduit 112. This increase in size results in a slower velocity of the working air as it enters the sorting channel 36. The size of the sorting channel 36 at the fluid inlet 26 can be based on the distance between the cover portion 116 of the outer guide wall 154 and the base plate 34. For example, the cover portion 116 can be angled to alter or adjust the size of the sorting channel 36.

[0041] As the sorting channel 36 extends away from the fluid inlet 26 and toward the fluid outlet 28, the size of the sorting channel 36 decreases (e.g., a third dimension along the airflow path 20 at the recycling tank assembly 24). This reduction in size can be gradual, driving an increase in airflow velocity. The reduction in size can be due to an inclination or angle of the cover portion 116 between the sides 156 of the inner guide wall 152 and the outer guide wall 154. A descent of the cover portion 116 between the inner guide wall 152 and the outer guide wall 154 (e.g., toward the base plate 34) can reduce the size of the sorting channel 36. It is conceivable that the sides 156 of the inner guide wall 152 and / or the outer guide wall 154 can also be angled toward the opposing guide walls 152, 154 to narrow the sorting channel 36.

[0042] Still referencing Figures 8 to 10 During operation, the suction source 18 ( Figure 1 The system is configured to create a vacuum effect along the airflow path 20 (including through the recovery tank assembly 24). The vacuum effect generates a working airflow that guides working air and collected liquid and / or solid matter along the airflow path 20 for collection. The working air is directed through the fluid inlet 26 and into the larger proximal end 110 of the sorting channel 36. The velocity of the working air is slowed, and the liquid carried by the working air is directed through the fluid-permeable portion 38 of the base plate 34 and into the liquid collection area 30.

[0043] Most liquids can be guided through the base plate 34 at or before bends or turns in the sorting channel 36. Bends and turns may make it more difficult for the liquid to be guided with the working airflow. Therefore, the liquid turns to flow downward through the base plate 34. Alternatively, the liquid can be guided along a generally linear path and blocked by the outer guide wall 154 forming the bend. Blocking the liquid allows it to be redirected downward and / or along the outer guide wall 154 and eventually through the base plate 34.

[0044] Liquid collection area 30 is typically located below the fluid-permeable portion 38 of base plate 34. In various respects, at least some working air can flow through the fluid-permeable portion 38 along with the liquid, which can facilitate the drawing of liquid through base plate 34. The working air then flows through airflow passage 172, airflow opening 174, optionally through filter 178, and through fluid outlet 28.

[0045] In the sorting channel 36, at least some working air and solid material carried by the working air continue to be guided across the base plate 34 and directed to the fluid outlet 28. As the working air flows through the narrowing section of the sorting channel 36, the velocity of the working air increases. This increased velocity can help carry the solid material to and through the guide opening 160 of the adjacent end wall 158. The end wall 158 may form a stop or barrier for the working air and solid material to help guide the solid material and working air into the solid collection area 32. The recovery system 16 may utilize the vacuum effect and gravity to draw liquid and solid material into the corresponding collection areas 30, 32.

[0046] Working air in the second chamber section 138 is directed through airflow opening 176, optionally through filter 178, and through fluid outlet 28. The two branches of working air (from liquid collection area 30 and solids collection area 32) re-merge upon exiting the recovery tank assembly 24. The working air flow passes through outlet connector 124, outlet conduit 118, and suction source 18 (…). Figure 1 It is discharged from the cleaning device 10.

[0047] refer to Figure 11 The base plate 34 may include a fluid-permeable portion 38 along a considerable portion or its entire length. In this respect, openings in the base plate 34 extend over the second chamber portion 138, which has a solid collection area 32. An inclined surface 188 may extend from the base plate 34 to at least the partition wall 134. The inclined surface 188 may be a solid surface to guide any liquid flowing over the base plate 34 above the second chamber portion 138 back to the first chamber portion 136 for collection in the liquid collection area 30. This inclined surface 188 facilitates the provision of a longer sorting channel 36 to separate liquids without affecting the solid matter in the solid collection area 32.

[0048] Now for reference Figure 12 The lid 148 may consist of at least two parts, such as a bottom or inner lid portion 194 and a top or outer lid portion 196. Lid portions 194, 196 may be hinged together or may be completely separable. Seals or gaskets may be provided at the engagement location between the lid portions 194, 196 to provide a leak-proof seal for the sorting channel 36. In the example where the lid 148 includes lid portions 194, 196, each lid portion 194, 196 may form part of the sorting channel 36 such that the sorting channel 36 is defined by and located between the two lid portions 194, 196. For example, the inner lid portion 194 is configured to engage the outer can wall 132, and the outer lid portion 196 engages the inner lid portion 194.

[0049] The inner cover portion 194 may include a lower wall portion or a first wall portion, a base plate 34 between the first wall portions, a guide opening 160, and a separator 170. The outer cover portion 196 may include a cover portion 116 and an upper wall portion or a second wall portion extending from the cover portion 116. The second wall portion mates with or engages with the first wall portion to form guide walls 152, 154 and an end wall 158, closing or forming a sorting channel 36. Each of the cover portions 194, 196 may also include a portion of a fluid inlet 26 and a fluid outlet 28. The configuration of the cover 148 having cover portions 194, 196 facilitates access to the sorting channel 36, such as for cleaning. Furthermore, in a configuration where the solids collection area 32 is located within the sorting channel 36 (see...), Figure 15 and Figure 16 The lid sections 194 and 196 can facilitate the disposal of collected solid materials.

[0050] Furthermore, the base plate 34 may be a removable component for cleaning or disposal of collected material. The cover portions 194, 196 may facilitate the removal of the base plate 34 from the cover 148. Additionally, it is conceivable that the cover 148 may be configured to include an outer cover portion 196 having a cover portion 116 and an upper wall portion, and another component (such as the housing 60) Figure 2A Alternatively, 2B) may include a base plate 34 and a lower wall portion. In these examples, a cover 148 may form part of a sorting channel 36, and one or more mating parts engage the cover 148 to form the complete sorting channel 36.

[0051] Now for reference Figure 13 and Figure 14 The recycling tank assembly 24 includes an additional or alternative configuration of a separator or base plate 210 for sorting channel 36. The remainder of the recycling tank assembly 24 may be identical to any configuration described above, differing primarily in the shape or configuration of the base plate 210. In such a configuration, the base plate 210 includes a liquid or fluid-permeable portion 212. The fluid-permeable portion 212 may be an orifice, opening, slot, etc., arranged at least near the fluid inlet 26.

[0052] The base plate 210 includes a recessed portion 214 near the fluid inlet 26 at its proximal end 110. In this respect, the base plate 210 has an initial downward ramp adjacent to the fluid inlet 26, which can be located anywhere along the sorting channel 36, followed by an upward ramp. In a non-limiting aspect, the upward ramp can be arranged at bends or curves in the sorting channel 36.

[0053] The recessed portion 214, alone or in combination with the cover portion 116, can help widen the sorting channel 36 near the fluid inlet 26 and subsequently narrow it. Furthermore, providing the recessed portion 214 or lowering a portion of the base plate 34 can help guide liquid downwards into the sorting channel 36 and ultimately into the liquid collection area 30. For example, as the velocity of the working air slows down due to the increased size caused at least partially by the recessed portion 214, liquid can begin to descend in the sorting channel 36 (i.e., adjacent to the base plate 210 in the recessed portion 214). A considerable amount of liquid can be guided through the base plate 210 in the recessed portion 214. Remaining liquid can continue to flow along the base plate 210, and due to the upward slope of the base plate 210, liquid can instead be guided into the upwardly sloped base plate 210, downwards / along the sloped surface, and through the base plate 210. The recessed portion 214 can help control the airflow velocity in the recovery tank assembly 24 and facilitate the separation of liquid into the liquid collection area 30.

[0054] Now for reference Figure 15 and Figure 16 The recycling tank assembly 24 includes a separator or base plate 220 for the sorting channel 36 and an additional or alternative configuration of the recycling tank 222. The remaining components of the recycling tank assembly 24 may be the same as or substantially similar to any of the previous configurations described herein. In this configuration, the recycling tank 222 defines a single collection chamber 224 for the liquid collection area 30, and the solid collection area 32 is defined in the sorting channel 36.

[0055] A base plate 220 extends between a fluid inlet 26 and a fluid outlet 28, and at least a portion 230 of the base plate 220 is fluid- or liquid-permeable. In some respects, a considerable portion 230 or the entire length of the base plate 220 is fluid-permeable and is positioned above the liquid collection area 30. Therefore, liquid can be guided through the base plate 220 at any point between the fluid inlet 26 and the fluid outlet 28.

[0056] The base plate 220 includes a recessed area 232, which can be similar to Figure 13 and Figure 14 The recessed portion 214 extends over a greater length of the base plate 220. The base plate 220 may slope downward near the fluid inlet 26 at its proximal end 110, which can help slow the air velocity and guide the liquid through the base plate 34, similar to the sloped surface of the recessed portion 214 described herein. Figure 13 and Figure 14The recessed region 232 can extend a considerable length of the base plate 220 and form a receiving space as a solids collection region 32. The distal end 114 of the sorting channel 36 can be inclined upwards to guide liquid to the liquid collection region 30 and retain solids in the solids collection region 32. The recessed region 232 forms a basket-like structure for holding solids above the collection chamber 224. Typically, liquid is guided through the base plate 220 at the proximal end 110, and solids are collected at or toward the distal end 114, thus improving the separation of liquid and solids.

[0057] The base plate 220 may be removable to dispose of solid matter collected on the base plate 220 and to pour liquids from the liquid collection area 30. In some aspects, the cover 148 may include cover portions 194, 196. Figure 12 This increases access to the solids collection area 32 and allows for easier removal of the base plate 220, or may include an outer cover portion 196 that mates with other components to form a sorting channel 36. The filter 178 may be positioned near the fluid outlet 28 to help retain solids and liquids in the collection areas 30, 32, thereby reducing the amount of liquid being directed toward the suction source 18. Figure 1 ( ) Guided debris. Filter 178 can also function as a stop or barrier to retain solid matter in solid collection area 32.

[0058] In some aspects, the recycling tank assembly 24 may include a movable baffle 238. The movable baffle 238 may retract or collapse, move out of the sorting channel 36, and expand, move into, or cross the sorting channel 36. The movable baffle 238 may be breathable. In these examples, the movable baffle 238 may serve as an additional filter 178 for debris, and as a stop for at least solid material at the distal end 114 of the sorting channel 36.

[0059] Alternatively, the movable baffle 238 may be generally fluid-impermeable or solid. In these examples, the movable baffle 238 may close the sorting channel 36, thereby forcing working air through the base plate 220 and the liquid collection area 30. The working air may flow back downstream of the baffle 238 through the base plate 220 to flow through the filter 178 and the fluid outlet 28. Forcing working air through the base plate 34 may help separate liquid into the liquid collection area 30 and retain solids in the solids collection area 32. Furthermore, when a mixture of liquid and solids is simultaneously captured by the recovery system 16, the movable baffle 238 may help pull liquid from the solids or increase the separation between the liquid and solids. The movable baffle 238 may help enhance the vacuum effect and / or control the rate at which working air passes through the recovery tank assembly 24 to facilitate the separation process.

[0060] Now for reference Figure 17 The recovery tank assembly 24 includes an additional or alternative configuration of a separator or base plate 250 for the sorting channel 36, which can be used with the single-chamber recovery tank 222 of 16 having a liquid collection area 30. The remaining components of the recovery tank assembly 24 may be the same as or substantially similar to any configuration described herein. In this configuration, the base plate 250 is liquid or fluid-permeable at the proximal end 110 of the sorting channel 36. The base plate 250 may be flat or recessed. A recessed configuration may help control the airflow velocity and help guide liquid through the fluid-permeable portion 252 of the base plate 250 and collect it in the liquid collection area 30.

[0061] Solids collection area 32 may be spaced apart from liquid collection area 30. In the illustrated configuration, solids collection area 32 is included in a distal container 256 located downstream of the fluid-permeable portion 252 of the base plate 250 at the distal end 114 of the sorting channel 36. The distal container 256 may be a recessed area of ​​the base plate 250 and may be... Figure 16 The recessed area 232 described herein operates in a similar manner. Alternatively, the distal container 256 may be a separate storage unit, such as a second single-chamber recovery tank 222. The size of the sorting channel 36 may be reduced between the fluid-permeable portion 252 on the liquid collection area 30 and the distal container 256 to increase airflow velocity to carry solid material.

[0062] The base plate 250 may be removable for disposing of collected solids. Furthermore, the base plate 34 may also have a section disposed within the space between the cover 148 and the collection tank 222 (e.g., a fluid-permeable portion 252), and a section outside this space (e.g., adjacent to the outer cover wall 150 and / or the outer surface of the collection tank 222) (e.g., a distal container 256). This can further separate the two collection areas 30, 32.

[0063] and Figure 15 and Figure 16 The configuration is similar in the example. Figure 17 The illustrated configuration can also utilize a movable baffle 238. In examples where the movable baffle 238 is solid or fluid-impermeable, a solid baffle 238 can form a liquid barrier. Furthermore, a solid baffle 238 can temporarily retain solid material in the sorting channel 36 upstream of the solid collection area 32, which can aid in the separation of liquid and solid material. Alternatively, the baffle 238 can be positioned at the distal end 114 of the sorting channel 36 to form a barrier or stop for solids near the distal container 256, thereby retaining or deflecting solid material into the distal container 256.

[0064] Refer again Figures 1 to 17The recycling system 16 described herein is configured to sort collected liquids into a liquid collection area 30 and collected solids into a solids collection area 32. The collection of liquids and solids in separate areas 30 and 32 may be more hygienic and allow for easier disposal of captured debris. The recycling system 16 directs a significant portion or almost all of the “dry” or solid matter to the solids collection area 32, and a significant portion or almost all of the “wet” matter or liquid to the liquid collection area 30. This sorting process can be completed by the consumer without any additional steps. At the end of the cleaning process, the consumer is left with an area 30 containing liquids and a second area 32 containing solids, from which liquids can be poured out without filtering out large amounts of solid debris, and from which solids can be disposed of more easily (e.g., without needing to clean “sticky” mixtures that result from the mixing of solids and liquids).

[0065] The use of this device offers several advantages. For example, the recovery system 16 can automatically separate liquids and solids in the cleaning device 10, which can be a portable or upright cleaner. Separation can occur when liquids are collected via the suction port 22, solids are collected via the suction port 22, or a mixture of liquids and solids is collected via the suction port 22. At least some (if not most) of the components for sorting liquids and solids can be included in the cover 148 or the outer cover portion 196 forming the cover 148. The cover 148 with the sorting components is removable for easy cleaning by the consumer.

[0066] Furthermore, the configuration of the sorting channel 36, through bending and changing its size, maximizes the efficiency of the sorting process in the recovery tank assembly 24. The sorting channel 36 is typically a horizontal channel for separating liquids and solids. Generally, liquids can be collected in the lower collection area 30 below the separator / bottom plate 34, while solids can be collected in the chamber portion 138 of the recovery tank 130. Figures 3 to 14 ), the recessed area 232 of sorting channel 36, ( Figure 15 and Figure 16 ), remote container 256 ( Figure 17The liquid can be disposed of in a separate tank 222 or in a separate container. Additionally, the base plate 34 can be removable to facilitate the disposal of solid debris or for cleaning. Furthermore, unlike filter-based systems, the recovery system 16 described herein first separates the liquid from the working air, and the solid matter is captured elsewhere, so that the collection of solid matter does not substantially inhibit the collection of the recovered liquid. Separating the solids from the liquid of typically dry materials is more hygienic and maximizes the user experience, including reducing the formation of hard solid-liquid mixtures in the cleaning device 10 and reducing or preventing clogging in system 16. Additional benefits or advantages can be achieved and / or attained.
