[0002] Pursuant to 35 USC §119(e), this application claims priority and benefit to U.S. Provisional Application No. 63 / 367,740 entitled “Extraction Cleaner,” filed July 6, 2022, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure generally relates to an extractor cleaner for cleaning surfaces. Background Technology

[0004] Extraction cleaners are used to clean carpets, upholstery, furniture, and other surfaces. They use a vacuum system and a fluid delivery system to extract dirt and debris from a surface. The fluid delivery system supplies cleaning fluids, such as water, cleaning solutions, or a mixture of both, from an onboard supply tank on the extraction cleaner to the surface to be cleaned. A recovery system utilizes an onboard suction source that recovers the fluid, dirt, and debris applied by the fluid delivery system. The recovered dirt and fluid are typically drawn through a nozzle on the cleaning tool, passing through a hose connected to the suction source, and into a recovery tank also onboard on the extraction cleaner. Summary of the Invention

[0005] A pull-out cleaner is provided, which has several features that enable a compact design to promote portability, while allowing for relatively large-capacity supply and return containers, both fixed to a base but easily removable. The structure of the pull-out cleaner's carrying handle allows for a taller supply and return container, thus providing the required container volume without increasing the width of the base. The pull-out cleaner can be, but is not limited to, a cordless portable pull-out cleaner.

[0006] The extraction cleaner within the scope of this disclosure may include a base, a supply can assembly, and a recovery can assembly. The base may include a housing having a first sidewall and a second sidewall opposite to the first sidewall. The base may have a supply can seat adjacent to the first sidewall and a recovery can seat adjacent to the second sidewall. The base may have a handle extending from the first and second sidewalls and over the housing. The handle may include a gripping portion, a first leg extending from the first sidewall to the gripping portion, and a second leg extending from the second sidewall to the gripping portion. The supply can assembly may be configured to be received by the supply can seat, wherein an inner wall of the supply can assembly mates with the first sidewall of the housing and the first leg of the handle, and extends along the first leg to the gripping portion. The recovery can assembly may be configured to be received by the recovery can seat, wherein an inner wall of the recovery can assembly mates with the second sidewall of the housing and the second leg of the handle, and extends along the second leg to the gripping portion. With this configuration, the handle is used to support the recovery tank assembly and the supply tank assembly over a larger range along the handle height than existing extraction cleaners, allowing the tank to also have a greater height, and without needing to increase the width of the tank or housing to achieve the desired tank volume.

[0007] The extraction cleaner within the scope of this disclosure may include a base having a housing, a supply can assembly, and a recovery can assembly. The housing may have a first sidewall and a second sidewall opposite to the first sidewall, a supply can seat adjacent to the first sidewall, a recovery can seat adjacent to the second sidewall, and a handle extending from the first and second sidewalls and extending over the housing. The supply can assembly may be configured to be received by the supply can seat, wherein the inner wall of the supply can assembly mates with the first sidewall of the housing and the handle. The recovery can assembly may include a recovery can configured to be received by the recovery can seat, wherein the inner wall of the recovery can assembly mates with the first sidewall of the housing and the handle. The recovery can assembly may include a recovery can cap on the recovery can opposite the recovery can seat. In an embodiment, the handle does not extend laterally outward over the recovery can cap. A latching assembly is operable to engage a feature at the inner wall of the recovery can assembly when the inner wall of the recovery can assembly mates with the second sidewall to latch the recovery can assembly to the base. For example, the base may have a notch, such as at the handle, and the latching assembly may include a spring-biased latch at the notch. This feature on the inner wall of the recycling can assembly can be a protrusion that extends into a recess and is engaged by a spring-biased latch when the inner wall of the recycling can assembly mates with the second side wall of the housing and the handle. In embodiments where the recess is located at the handle, the recycling can assembly is secured near its upper extension, which provides stability for extracting the cleaner during use.

[0008] Additionally, the suction hose and liquid delivery line can be secured to the base via a mounting member, which may have features for limiting the swaying and / or twisting of the suction hose relative to the base during use. For example, a suction cleaner within the scope of this disclosure may include a base having a housing. The suction source may be within the housing and operable to generate a working airflow. A fluid pump may also be within the housing. The suction cleaner may include a first coupling for fluid communication with the fluid pump and a second coupling for fluid communication with the suction source. The first and second couplings may be disposed adjacent to each other on the base. The suction cleaner may include a suction hose having an inlet and an outlet through which the working airflow is drawn through the suction hose, the outlet being configured to connect to the second coupling. The mounting member may be supported on and surround at least a portion of the opening in the outer wall of the suction hose adjacent to the outlet. The fluid delivery line can be configured to connect to a first connector and be routed through an opening in the outer wall of the suction hose, such that the fluid delivery line has a first portion extending through the connector to the opening, and a second portion extending inside the suction hose between the opening and the inlet of the suction hose. Thus, the fluid delivery line is spaced apart from the outlet of the suction hose to avoid obstructing or reducing flow at the outlet. The connector helps ensure that the suction hose and the fluid delivery line extending through the suction hose remain connected to the base. The suction hose and fluid delivery line can be conveniently and uniformly removed by the customer by removing the connector from the base.

[0009] Despite the space constraints of a compact, portable extraction cleaner, the battery pack can be housed within the housing, and the housing can be configured to facilitate cooling of the battery pack. For example, the extraction cleaner may include a base having a housing defining an inner cavity and having a first sidewall, a second sidewall opposite the first sidewall, a supply canister adjacent to the first sidewall, a recovery canister adjacent to the second sidewall, and a handle extending from the first and second sidewalls above the top wall of the housing. The extraction cleaner may include a motor and impeller assembly disposed within the cavity between the recovery canister and the supply canister, and operable to generate a working airflow. The extraction cleaner may also include a battery pack disposed within the housing above the motor and impeller assembly, and a cooling fan disposed within the housing between the battery pack and the motor and impeller assembly and driven by the motor and impeller assembly. The inner cavity may include a cooling space surrounding the battery pack and extending between the battery pack and the housing. The housing may have an air inlet adjacent to the battery pack through which the cooling fan draws ambient air into the cooling space. In other words, the housing and air inlet are configured to facilitate cooling of the battery pack. In one embodiment, the extraction cleaner may include a printed circuit board assembly located inside the housing above the battery pack and below the top wall of the housing.

[0010] These and other features, advantages and objectives of this disclosure will be further understood and appreciated by those skilled in the art upon reference to the following description, claims and drawings. Attached Figure Description

[0030] The foregoing features and advantages, as well as other features and advantages, of this teaching will be readily understood from the following detailed description of the mode of implementation of this teaching when taken in conjunction with the accompanying drawings. It should be understood that while embodiments may be described individually in the following drawings, individual features in these embodiments may be combined to form other embodiments. Detailed Implementation

[0031] The embodiments shown in this disclosure primarily concern combinations of method steps and apparatus components related to the extraction cleaner. Therefore, where appropriate, apparatus components and method steps have been indicated by conventional symbols in the accompanying drawings, with only those specific details relevant to understanding the embodiments of this disclosure shown so as not to obscure the disclosure due to details readily understood by one of ordinary skill in the art as described herein. Furthermore, the same reference numerals denote the same elements in the specification and drawings.

[0032] refer to Figures 1 to 18 This disclosure generally relates to a suction cleaner 10 and several aspects thereof for improved performance, compactness, ease of use, and other benefits. The suction cleaner 10 includes a base 12 having a housing 14 and a handle 16. The housing has a recessed area for selectively receiving components, formed by a laterally extending portion 14A and a vertically extending side portion 14B. The handle extends upward from the housing 14. The handle 16 includes a bottom portion 16A, a gripping portion 16B, a first leg 16C extending between the bottom portion 16A and the gripping portion 16B, and a second leg 16D extending between the bottom portion 16A and the gripping portion 16B. As further discussed herein, both a supply can assembly 18 and a recovery can assembly 20 are mounted on the base 12 and mate with and match the housing 14 and the handle 16. A suction hose 22, including a flexible hose portion 22A and a hose fitting 22B, is shown as a lower skirt 24 surrounding the base 12 (see [link to documentation]). Figure 2 ) Entangling.

[0033] refer to Figure 1 and Figure 2 When the cleaning tool 26 is secured to the wand 30, which connects to the hose connector 32 at the inlet 28, the cleaning tool is in fluid communication with the inlet 28 of the suction hose 22. The cleaning tool 26 includes a suction nozzle 34 and a stirrer (see [link]). Figure 1 Such as, but not limited to, brush bristles. A spray nozzle 36 is disposed on the underside of the cleaning tool 26 for selectively distributing cleaning fluid onto the surface S to be cleaned (e.g., by pressing a trigger disposed on the underside of the lever 30). When the cleaning tool 26 is not in use, the retainer 38 (see...) Figure 2 and Figure 12 Support rod 30.

[0034] The housing 14 defines the inner cavity 40 (e.g.) Figure 10 and Figure 12(As shown), the inner cavity 40 is divided into a lower cavity portion 40A and an upper cavity portion 40B by an inner wall 42, which serves as a motor mount. The lower cavity portion 40A houses a suction source 44 (such as a motor and impeller assembly 46, 48) positioned therein, including a suction motor 46 and an impeller 48. The upper cavity portion 40B houses a battery pack 56 and a printed circuit board assembly (PCBA) 58 discussed herein, the battery pack including one or more battery cells 56A and a battery cover 56B. The motor and impeller assemblies 46, 48 are disposed in the inner cavity 40 between the supply tank 80 and the recovery tank 82 (see...). Figure 6 And this will be discussed in this article.

[0035] refer to Figure 1 and Figure 2 The outlet 84 of the suction tubing 22 is located via one or more conduits 86 disposed within the lumen 40 (see...). Figure 10 The cleaning tool 26 is in fluid communication with the suction source 44 and the recovery tank assembly 20, and is held to the base 12 via a mounting member 88 for improved stability. This mounting member has an inner mounting portion 88A and an outer mounting portion 88B defining an opening 88C, as further discussed herein. The suction source 44 is in fluid communication with the suction nozzle 34 of the cleaning tool 26 via a conduit 86, a suction hose 22, and a rod 30 to generate a working airflow, and the recovery tank assembly 20 separates and collects fluid and debris from the working airflow for subsequent disposal.

[0036] The supply tank assembly 18 is in fluid communication with the spray nozzle 36 of the cleaning tool 26 via a fluid delivery line 104. The fluid delivery line 104 includes an end 104A near the base 12, a first portion 104B extending through the mounting member 88, and a second portion 104C extending inside the suction hose 22 (see, for example...). Figure 10 and Figure 14 Pressurized fluid is delivered from the supply tank assembly 18 through this second section via a fluid pump 106 disposed within the inner cavity 40. The fluid pump 106 is connected via a fluid line 108 (in...) Figure 10 (shown in cross section) is in fluid communication with supply tank assembly 18.

[0037] During operation, the extraction cleaner 10 draws in a working airflow carrying fluid and debris through suction nozzle 34 and draws the working airflow into the recovery tank 110 of the downstream recovery tank assembly 20. The recovery tank 110 includes a lower wall portion 110A extending from a bottom wall 110B and an outer wall 110C extending from the lower wall portion 110A to a top 110D of the recovery tank 110. In the recovery tank 110, the fluid and debris are substantially separated from the working airflow. The working airflow then exits the recovery tank assembly 20 and passes through motor and impeller assemblies 46, 48 before being discharged from the extraction cleaner 10. The collected fluid and debris in the recovery tank 110 can be periodically emptied by removing the recovery tank assembly 20 from the base 12 and removing the cover 118 having the top 118A of the recovery tank assembly 20, as discussed herein.

[0038] exist Figure 1 and Figure 2 In the diagram, the supply tank assembly 18 and the recovery tank assembly 20 are shown mounted on the base 12, and the suction hose 22 is shown wound around the base 12. For cleaning surface S, the suction hose 22 is extended from the base 12, and the suction nozzle 34 of the cleaning tool 26 is positioned adjacent to it. Figure 2 The surface S shown is placed as described. Surface S can be, for example, any type of flooring, including soft surfaces (such as carpets and mats, upholstered furniture) and hard surfaces (such as tile, wood, vinyl, and laminate surfaces). However, the aspects disclosed herein can be implemented on other types and configurations of cleaners within the scope of this disclosure.

[0039] refer to Figure 3 and 4 For the purposes of describing the accompanying drawings, the terms “up,” “down,” “right,” “left,” “back,” “front,” “vertical,” “horizontal,” “inner,” “outer,” and their derivatives will refer to the user’s position in front of the dispenser 10 (e.g., facing). Figure 4 Viewed from the angle of the extraction cleaner 10 (limiting the front part 120 of the extraction cleaner 10), as shown... Figure 4 A directional extraction cleaner 10. The rear wall 122 of the housing 14 is located at the rear 128 of the extraction cleaner 10 and has an air inlet 124, which is shown as being partially covered by an inlet grille 126. Ambient air is drawn in through the air inlet 124 to cool the battery pack 56. Figure 10 and Figure 12 (as shown), as further discussed in this article.

[0040] The front portion 120 of the extractor cleaner 10 is opposite to the rear portion 128. It should be understood that the front portion 120 and the rear portion 128 are defined as such for discussion purposes only. The front wall 130 of the housing 14 is shown at the front portion 120. The rear wall 122 extends parallel to the front wall 130. The first side 132 of the extractor cleaner 10 is... Figure 4 Located on the right side, the second side 134 of the cleaner 10 is in the middle. Figure 4 The center is located on the left. Figure 2 The vertical axis V indicates the upward direction (upward arrow) and the downward direction (downward arrow). The horizontal axis L indicates the horizontal outward direction (a left-pointing arrow on the horizontal axis L, also called outward) and the horizontal inward direction (a right-pointing arrow on the horizontal axis L, also called inward). Compared to the outer part or surface, the inner part or surface is closer to the vertical center axis CA of the extraction cleaner 10 along the horizontal axis L (or along the horizontal axis perpendicular to the horizontal axis L).

[0041] The housing 14 includes a first sidewall 136 that extends from the front wall 130 to the rear wall 122 and is located at the first side 132 relative to the central axis CA (see example). Figure 2 and Figure 6 The first sidewall 136 includes a projecting vertical post 136A between the rear planar portion 136B and the front planar portion 136C. The housing 14 also includes a second sidewall 138 that also extends from the front wall 130 to the rear wall 122 and is closer to the second sidewall 134 relative to the central axis CA (see example...). Figure 6 The second sidewall 138 includes a projecting vertical column 138A between the rear plane portion 138B and the front plane portion 138C.

[0042] The top wall 140 of the housing 14 includes a rear top wall portion 140A that extends forward from the rear wall 122 between the first side wall 136 and the second side wall 138 to the bottom portion 16A of the handle 16, as shown. Figure 2 and Figure 9 As best shown. The top wall 140 of the housing 14 also includes a front top wall portion 140B, which extends rearward from the front wall 130 between the first side wall 136 and the second side wall 138 to the bottom portion 16A of the handle 16, as shown. Figure 9 As shown. The top wall 140 and the bottom portion 16A of the handle 16 extend above the upper cavity portion 40B of the inner cavity 40, as... Figure 12 As shown. The handle 16 extends above the top wall 140.

[0043] like Figure 2 and Figure 5As shown, the handle 16 includes a gripping portion 16B, a first leg 16C extending from a first sidewall 136 to the gripping portion 16B, and a second leg 16D extending from a second sidewall 138 to the gripping portion 16B. The bottom portion 16A, the gripping portion 16B, and the legs 16C and 16D together define an opening 142 through which the fingers of the hand can extend when the hand grips the gripping portion 16B to carry and extract the cleaner 10.

[0044] The first leg 16C is continuous with the protruding vertical post 136A of the first sidewall 136 and extends upward from the protruding vertical post of the first sidewall, as shown below. Figure 5 and Figure 6 As best shown in the diagram. The second leg 16D is continuous with the protruding vertical post 138A of the second sidewall 138 and extends upward from the protruding vertical post of the second sidewall, as shown in the diagram. Figure 5 and Figure 9 The best result is shown in the middle.

[0045] Figure 6 This is a perspective view of the extraction cleaner 10, showing the supply tank seat 80 and the recovery tank seat 82 of the base 12. The supply tank seat 80 is adjacent to the first sidewall 136. The housing 14 includes a first lower sidewall 150, which is an arcuate or bow-shaped vertically extending wall that surrounds the supply tank seat 80 from the front wall 130 to the rear wall 122, partially enclosing the supply tank seat 80 such that the supply tank seat is closed from the first side 132 and open from above. The first lower sidewall 150 is shorter than the first sidewall 136.

[0046] In contrast, the shell 14 forms a lower edge 152 that wraps around the recovery tank seat 82 from the front wall 130 to the rear wall 122. This same edge 152 extends at the bottom of the first lower sidewall 150, as... Figure 5 and Figure 6 As shown. Therefore, the lateral exposure of the recovery tank seat 82 (at the second side 134) is greater than the lateral exposure of the supply tank seat 80 at the first side 132, as... Figure 5 As shown. This facilitates the removal of the recycling tank assembly 20 in the manner discussed herein.

[0047] Additionally, because the recycling tank seat 82 is positioned lower than the supply tank seat 80, the recycling tank 110 has a greater height than the supply tank 154 of the supply tank assembly 18. The supply tank 154 includes a lower wall portion 154A extending from the bottom wall 154B and an outer wall 154C extending from the lower wall portion 154A. Given the greater height of the recycling tank 110, the recycling tank 110 and the supply tank 154 have the same width and length, and each extends to approximately the same height with respect to the handle 16; the recycling tank 110 has a larger internal volume than the supply tank 154.

[0048] Since the recovery tank 110 should have sufficient volume to accommodate the maximum fill volume of the supply tank 154 after picking up the dispensed cleaning fluid, as well as the additional internal volume for separating the air portion of the working airflow, setting the recovery tank seat 82 lower achieves these objectives while still keeping the top portion 156 (including the top 156A) of the supply tank 154 and the recovery tank cover 118 at approximately the same height. Each of the supply tank 154 and the recovery tank 110 with the cover 118 extends to a height slightly below the top of the gripping portion 16B so as not to interfere with access to the gripping portion 16B. Additionally, by placing the supply tank seat 80 higher (e.g., raised above the skirt 24 and edge 152 via the first lower sidewall 150), the cavity 40 can extend below the supply tank seat 80 to the first lower sidewall 150, thereby providing additional encapsulation space for the fluid lines 108 and other components, such as... Figure 10 As shown.

[0049] Figure 7 A supply tank assembly 18 is shown, comprising a supply tank 154 having an integral supply tank top portion 156, and a cap assembly 158 threadedly connected to a neck 160 of the supply tank 154. The cap assembly 158 includes an externally threaded ring 162 and a cap 164, the ring 162 being rotatably mounted on the cap such that the ring 162 is rotatable relative to the cap 164. The cap assembly 158 is removable, allowing the supply tank 154 to be filled with cleaning fluid through the neck 160. A plunger valve 166 is disposed in the central column of the cap 164, and... Figure 7 It is shown in dashed lines.

[0050] like Figure 6 As shown, the supply tank seat 80 has a receiving opening 168 and a seal 170 disposed around the receiving opening 168. For illustrative purposes, the seal 170 is shown at the opening 168, but the seal can be carried on a cap 164 to seal the cap 164 at the receiving opening 168. A screen 172 is disposed over the opening 168. The cap 164 is sized to be received within the receiving opening 168, and the receiving part 174 functionally engages with the cap 164 at the opening 168 to actuate a valve 166, thereby opening the valve 166 and allowing flow from the supply tank 154 through the cap 164, and then through the fluid line 108 extending to the fluid pump 106. Figure 10 (As shown in the diagram). Therefore, the supply tank assembly 18 is fluidly connected to the fluid pump 106 at the supply tank seat 80.

[0051] The user places the supply can assembly 18 on the supply can seat 80 to actuate the valve 166. The lower wall portion 154A of the supply can 154 is supported against the inner side of the first lower side wall 150 and has an arcuate shape that matches the arcuate shape of the first lower side wall 150. The outer wall 154C of the supply can 154 above the lower wall portion 154A also has an arcuate shape that matches the arcuate shape of the first lower side wall 150, extending flush with the first lower side wall 150 above it. The bottom wall 154B of the supply can 154 is supported on... Figure 6 The supply tanks shown are located at 80 locations.

[0052] like Figure 7 As shown, the supply tank 154 of the supply tank assembly 18 has an inner wall 180 that forms a vertical inner channel 180A between a rear planar portion 180B and a front planar portion 180C. The vertical channel 180A extends from the bottom wall 154B of the supply tank assembly 18 (e.g., the bottom wall 154B of the supply tank 154) to the top of the supply tank assembly 18 (e.g., to the top 156A of the top portion 156), opening upward at the top 156A of the top portion 156.

[0053] The supply can assembly 18 is configured to be received by the supply can holder 80, wherein the inner wall 180 mates with the first side wall 136 of the housing 14 and the first leg 16C of the handle 16, extending along the first leg 16C to the gripping portion 16B, as shown. Figure 3 As best shown in the diagram. Specifically, the protruding vertical column 136A mates with and is nested within the vertical channel 180A of the supply can 154, and the first leg 16C also mates with and is nested within the vertical channel 180A above the vertical column 136A. When the supply can 154 is placed at the supply can holder 80, the vertical channel 180A extends to the gripping portion 16B.

[0054] The first leg 16C is vertical and laterally longer than the vertical column 136A (see...). Figure 5 The first leg 16C will therefore fill the vertical channel 180A, while a gap 182 will be left in the portion of the vertical channel 180A that is not filled by the vertical post 136A (see [link]). Figure 10 Because the vertical channel 180A extends vertically from the bottom wall 154B to the top 156A of the top portion 156, the handle 16 does not extend laterally outward above the supply can assembly 18. In other words, the supply can assembly 18 is positioned adjacent to the handle 16 such that when the supply can assembly 18 is placed on the supply can seat 80, no part of the supply can assembly 18 is directly below the first leg 16C. In this way, the supply can assembly 18 is not affected by any portion of the handle 16 extending laterally above the top 156A of the supply can 154.

[0055] The front planar portion 136C of the first sidewall 136 abuts with the front planar portion 180C of the supply tank 154, and the rear planar portion 136B of the first sidewall 136 abuts with the rear planar portion 180B of the supply tank 154. For example... Figure 1 and Figure 6 As shown in the diagram, the first leg 16C is narrower than the first sidewall 136 of the housing 14. Additionally, the inner wall 180 of the supply can 154 is wider than the first leg 16C. Therefore, when the supply can assembly 18 is placed in the supply can seat 80, a portion of the inner wall 180 (e.g., the top region of the front flat portion 180C and the top region of the rear flat portion 180B) is located on opposite sides of the handle 16 (including the front of the handle 16 (the top region of the front flat portion 180C, such as...). Figure 1 and Figure 9 (as shown) and the rear of the handle 16 (the top area of ​​the rear flat portion 180B, also as shown) Figure 1 and Figure 9 As shown, it is exposed on the housing 14.

[0056] Figure 8 A recycling can assembly 20 is shown, which includes a recycling can 110 and a recycling can lid 118 removably coupled to the recycling can 110 for emptying the recycling can 110. Specifically, the recycling can lid 118 is mounted to the top 110D of the recycling can 110 opposite the bottom wall 110B of the recycling can 110.

[0057] Refer again Figure 6 as well as Figure 8 The recycling tank holder 82 has a first receiving opening 184 and a second receiving opening 186. When the recycling tank assembly 20 is received by the recycling tank holder 82, the recycling tank 110 has a first opening 188 that mates with the first receiving opening 184 and a second opening 190 that mates with the second receiving opening 186. The recycling tank assembly 20 is fluidly connected to the working gas flow via the first receiving opening 184, which provides a mixture of dirty liquid and air from the suction hose 22. The mixture of dirty liquid and air travels upward in the inlet pipe 192 within the recycling tank 110 to the deflection chamber 200 within the cap 118, causing the liquid to fall to the bottom of the recycling tank 110 by gravity, thereby separating it from the air.

[0058] Air can then exit the recovery tank 110 through the opening 202 at the bottom of the cover 118, travel through the cover 118 to the outlet pipe 204, to the second opening 190, and through the conduit 86 to the motor and impeller assemblies 46, 48 for discharge from the extraction cleaner 10. The float 206 moves upward to close the opening 202 in the cover 118 at a predetermined level, preventing air from flowing through the opening 202, thus indicating that the recovery tank 110 is full and prompting the user to empty the recovery tank 110.

[0059] The lower wall portion 110A of the recycling tank 110 is supported against the lower edge 152 and has an arcuate shape matching the arcuate shape of the inner side of the lower edge 152. The outer wall 110C of the recycling tank 110 above the lower wall portion 110A also has an arcuate shape matching the arcuate shape of the lower edge 152, extending flush with the lower edge 152 above it. The outer wall 110C is opposite to the inner wall 210. The bottom wall 110B of the recycling tank 110 is placed against the recycling tank base 82, as... Figure 10 As shown.

[0060] like Figure 8 As shown, the recycling tank 110 has an inner wall 210 that forms a vertical inner channel 210A between a rear planar portion 210B and a front planar portion 210C. This vertical inner channel extends from the bottom wall 110B of the recycling tank assembly 20 (e.g., the bottom wall 110B of the recycling tank 110) to the top of the recycling tank assembly 20 (e.g., to the top 118A of the cover 118), opening upward at the top 118A of the cover 118. In other words, the vertical channel 210A extends along both the recycling tank 110 and the recycling tank cover 118 as a continuous recess in both the recycling tank 110 and the recycling tank cover 118.

[0061] The recycling can assembly 20 is configured to be received by the recycling can seat 82, wherein the inner wall 210 mates with the second side wall 138 of the housing 14 and the second leg 16D of the handle 16, extending along the second leg 16D to the gripping portion 16B, as shown. Figure 3 and Figure 10 As best shown in the diagram. Specifically, the protruding vertical column 138A engages with and is nested within the vertical channel 210A of the recycling tank 110, and the second leg 16D also engages with and is nested within the vertical channel 210A of the recycling tank 110 above the vertical column 138A.

[0062] When the recycling can 110 is placed in the recycling can seat 82, the vertical post 138A extends to the gripping portion 16B. The second leg 16D is vertical and protrudes laterally beyond the vertical post 138A, filling the vertical channel 210A, leaving a gap 212 in the portion of the vertical channel 210A not filled by the vertical post 138A. Because the vertical channel 210A extends vertically from the bottom wall 110B to the top 118A of the cover 118, the handle 16 does not extend laterally outward beyond the recycling can assembly 20. In other words, the recycling can assembly 20 is adjacent to the handle 16 such that when the recycling can assembly 20 is placed in the recycling can seat 82, no part of the recycling can assembly 20 is directly below the second leg 16D. In this way, the recycling can assembly 20 is not affected by any portion of the handle 16 extending laterally above the top 118A of the cover 118.

[0063] The front plane portion 138C of the second sidewall 138 abuts against the front plane portion 210C of the recycling tank 110, and the rear plane portion 138B of the second sidewall 138 abuts against the rear plane portion 210B of the recycling tank 110. For example... Figure 9 As shown in the optimal configuration, the second leg 16D is narrower than the second sidewall 138 of the housing 14. Additionally, the inner wall 210 of the recycling tank 110 is wider than the second leg 16D. Therefore, when the recycling tank assembly 20 is placed at the recycling tank seat 82, a portion of the inner wall 210 (e.g., the top region of the front planar portion 210C and the top region of the rear planar portion 210B) is located on opposite sides of the handle 16 (including the front of the handle 16 (the top region of the front planar portion 210C, such as...). Figure 12 (as shown) and the rear of the handle 16 (the top area of ​​the rear flat portion 210B, also as shown) Figure 12 As shown, it is exposed on the housing 14.

[0064] refer to Figure 10 and Figure 11 As discussed herein, the taller recovery tank 110, with greater lateral exposure than the supply tank 154 (due to the shorter edge 152 compared to the first lower sidewall 150), is releasably latched to the base 12 to ensure stability during use of the extraction cleaner 10 and to facilitate easy removal for emptying the recovery tank 110. Specifically, the latching assembly 220 (in) engages with the second sidewall 138 of the housing 14 when the inner wall 180 of the recovery tank 110 mates with the housing 14. Figure 10 and Figure 11 (As best shown) Operable to latch the recycling tank assembly 20 to the base 12. Specifically, the recycling tank assembly 20 is latched to the handle 16 of the base 12, and more specifically, the recycling tank assembly is latched to the second leg 16D of the handle 16.

[0065] The inner wall 180 of the recycling tank 110 includes a feature engaged by a latching assembly 220 to latch the recycling tank assembly 20 to the base 12 when the inner wall 180 of the recycling tank 110 engages with the second side wall 138. This feature at the inner wall 180 of the recycling tank assembly 20 is a protrusion 224 having an inclined lip 224A, such as... Figure 8 and Figure 11 As shown in the best view, the protrusion is near the top of the recycling tank 110, just below the cover 11, and extends from the recycling tank 110 in the vertical channel 210A.

[0066] The handle 16 of the base 12 includes a notch 222 that aligns with a protrusion 224 when the inner wall 180 of the recycling tank 110 engages with the second side wall 138. More specifically, the second leg 16D of the handle 16 includes a notch 222, as shown in... Figure 9 It is also clearly visible in the middle. The latch assembly 220 includes a spring-biased latch 226 at the notch 222, as... Figure 11 As shown. The spring-biased latch 226 includes a latch body 228 having a central post 228A and an engagement surface 228B. A spring 230 is disposed around the central post 228A of the latch body 228 and is caught between the inner surface 232 of the latch body 228 and the inner surface 234 of the gripping portion 16B of the handle 16. The spring 230 may be, but is not limited to, a compression spring, and pushes the latch body 228 outward to... Figure 11 The latch position is shown, in which the latch body engages the protrusion 224.

[0067] The protrusion 224 has a beveled lip 224A, and the engagement surface 228B of the latch body 228 is rounded, thereby allowing the engagement surface 228B to slide over the beveled lip 224A when the recovery can 110 moves laterally inward to engage with the second sidewall 138, and when the protrusion 224 moves laterally inward into the recess 222. As the protrusion 224 moves inward into the recess 222, the latch body 228 moves against the biasing force of the spring 230 via the beveled lip 224A, and then moves by the biasing force to engage the engagement surface 228B with the beveled lip 224A, thereby latching the recovery can 110 to the base 12. The spring 230 is selected to have a spring stiffness sufficient to hold the spring-biased latch 226 in the latched state during use of the extraction cleaner 10.

[0068] To unlock the recycling can assembly 20 from the base 12, the user pulls on a protrusion 236 on the outer wall 110C of the recycling can 110, which is opposite the inner wall 210 and the latch assembly 220. The protrusion 236 can also be referred to as a pull member or pull feature because it has a downwardly opening cavity 238 in which the user's finger can remain when pulling laterally outward on the protrusion 236, similar to the operation of a drawer pull. The protrusion 236 and the spring-biased latch 226 are configured to allow for... Figure 11 The force in the direction of arrow F pulls the protrusion 236 laterally outward away from the handle 16, thereby unlocking the latch assembly 220 by disengaging the spring-biased latch 226 from the protrusion 224.

[0069] As the protrusion 224 moves laterally outward with the recovery tank 110, it forces the latch body 228 upward, thereby compressing the spring 230. The edge 152 is very low on the recovery tank 110 and has an outwardly flared shape, which... Figure 10 The difference is obvious. This facilitates allowing the recycling can assembly 20 to pivot slightly outward about the edge 152 when the protrusion 236 is pulled laterally outward and the latch assembly 220 is unlocked (e.g., disengaged from the protrusion 224). Once the latch assembly 220 is unlocked, the user can lift the recycling can assembly 20 upward to remove it from the recycling can seat 82.

[0070] The supply can assembly 18 is connected via a spring-biased latch 240 housed below the supply can seat 80 (e.g. Figure 6 The latch 240 (shown) is latched to the base 12. The latch 240 is biased toward the receiving opening 168 by a spring 242 (indicated by a hidden line or dashed line), which is also housed below the supply can holder 80. When the supply can assembly 18 is positioned in the supply can holder 80, the latch 240 can be positioned at the flange 244 (see...). Figure 7 The neck 160 of the supply can 154 is engaged below. To remove the supply can assembly 18, the user pulls the supply can assembly 18 upwards, wherein the neck 160 is pushed laterally outwards on the latch 240 sufficient to overcome the spring 242 and cause the latch 240 to retract from the neck 160. To refill the supply can 154, the supply can 154 is inverted such that the cap 164 is facing upwards and the top portion 156 is facing downwards, the cap 164 is removed, and cleaning fluid is poured into the supply can 154 through the neck 160.

[0071] Reference Figure 10 and Figure 12A cooling fan 246 is disposed within cavity 40 of housing 14, between battery pack 56 and motor and impeller assemblies 46, 48, and is rotatably driven by motor and impeller assemblies 46, 48. Battery pack 56 is disposed within cavity 40 of housing 14 above motor and impeller assemblies 46, 48. Battery pack 56 may include multiple interconnected battery cells 56A and battery covers 56B. Battery cells 56A can be recharged via an external power source (such as a wall plug), which can be connected via a power cord. Figure 2 The charging port 248 shown is operatively connected to the battery cell 56A via wiring extending from the charging port 248 into the battery pack 56 within the cavity 40. In the illustrated embodiment, the extractor cleaner 10 is cordless because it is not equipped with a wire for connecting to an external power source to power the extractor cleaner 10 during use. Instead, the battery pack 56 powers the extractor cleaner 10 during use, which increases the operability of the extractor cleaner 10 during use.

[0072] PCBA 58 is disposed above the battery pack 56 within the cavity 40 of the housing 14 and can be mounted to the inside of the top wall 140 of the housing 14 and / or the inside of the bottom portion 16A of the handle 16. User interface 250 is disposed outside the bottom portion 16A of the handle 16 and operatively connected to PCBA 58. User interface 250 may include multiple pressable buttons, switches, touch features, or other components that enable the user to control the operation of the extraction cleaner 10, such as by turning the power of the extraction cleaner 10 on or off, selecting operating modes, etc.

[0073] like Figure 2 and Figure 10 As best shown, at least some of the user interface 250 rises above the exterior of the bottom portion 16A. For example, the top surfaces 250A, 250B of at least some buttons of the user interface 250 extend into the opening 142 above the outer surface 252 of the bottom portion 16A.

[0074] Additionally, the handle 16 and housing 14 are configured to help prevent water from entering at the user interface 250. For example, the handle 16 has an inner ring portion 254 that defines the bottom portion 16A, the underside of the grip portion 16B, the inner side of the first leg 16C, and the inner side of the second leg 16D, forming an opening 142. Figure 1 and Figure 9 Clearly visible in the image, the inner ring portion 254 has a front periphery defining the front interface FI, at which the inner ring portion 254 mates with the top side of the gripping portion 16B, the outer sides of the legs 16C and 16D, and the front top wall portion 140B of the housing 14. Similarly, as Figure 2As clearly visible in the image, the inner ring portion 254 has a rear periphery that defines the rear interface RI, at which the inner ring portion 254 engages with the top side of the gripping portion 16B, the outer sides of the legs 16C and 16D, and the rear top wall portion 140A of the housing 14.

[0075] The inner ring portion 254 bends outward and downward from the outer surface 252 of the bottom portion 16A at the inclined surface 256 to the rear interface RI (in Figure 3 and Figure 12 (as shown in the best example), and in Figure 1 The inclined surface 258 shown (also) Figure 9 As shown in the diagram, the bottom portion 16A curves outward and downward from its outer surface 252 to the front interface FI. In this way, both the front interface FI and the rear interface RI are on the outside and below the user interface 250 to help prevent water from entering the inner cavity 40 of the housing 14 at the user interface 250.

[0076] The housing 14 is configured such that the inner cavity 40 includes a cooling space 260 extending around the battery pack 56 between the battery pack 56 and the housing 14. More specifically, the cooling space 260 extends above the battery pack 56 and below the PCBA 58 (e.g., between the top wall 140 and the battery pack 56, between the front wall 130 and the battery pack 56, and between the rear wall 122 and the battery pack 56, all as follows). Figure 12 (As shown). Additionally, the cooling space 260 extends between the first sidewall 136 and the battery pack 56, and between the second sidewall 138 and the battery pack 56, as shown. Figure 10 As shown. The cooling fan 246 is located between the inner wall 42 and the battery pack 56, directly below the battery pack 56. There are no other components between the cooling fan and the battery pack.

[0077] When the cooling fan 246 is powered on (e.g., around...) Figure 10 and Figure 12 When the vertical axis A1 (shown) rotates, ambient air from outside the housing 14 is drawn into the cooling space 260 by the cooling fan 246 through the air inlet 124. At least a portion of the rear wall 122 extends substantially parallel to the axis of rotation A1 of the cooling fan 246, such that the air drawn in through the air inlet 124 is at an angle to the axis of rotation A1, and the flow path P1 of the ambient air drawn into the cooling space 260 by the cooling fan 246 through the air inlet 124 is non-linear. At least a portion of the front wall 130 also extends substantially parallel to the axis of rotation A1. It should be understood that the air inlet 124 may alternatively be provided in the front wall 130.

[0078] Figure 12An example of this flow path P1 is shown. Flow path P1 includes representative branches P1A and P1B. At least some of the ambient airflow entering through air inlet 124 is drawn downward between the rear wall 122 of housing 14 and battery pack 56, as indicated by branch P1A of flow path P1. At least some of the ambient airflow entering through air inlet 124 flows above the top of battery pack 56 and flows downward between the front wall 130 and battery pack 56, as indicated by branch P1B of flow path P1. Similarly, some of the ambient airflow entering through air inlet 124 may cross the top of battery pack 56 and flow downward between the first side wall 136 and battery pack 56, while some may cross the top of battery pack 56 and flow downward between the second side wall 138 and battery pack 56. In other words, due to the arrangement of air inlet 124, cooling fan 246, and cooling space 260, cooling air generally flows around the entire battery pack 56.

[0079] The non-linear flow path P1 helps minimize or prevent stagnant areas within the cavity 40. As air is drawn in, the warmer air within the cavity 40 is expelled by the cooling fan 246. Ambient air can flow over and around all sides of the battery pack 56 within the cooling space 260. The superior or improved cooling of the battery pack 56 provided by the arrangement of the cooling space 260, air inlet 124, and cooling fan 246 can extend the charging and / or lifespan of electrical components, including the motor 46, PCBA 58, and battery pack 56.

[0080] As discussed above, the fluid delivery line 104 extends through the suction hose 22 and is fluidly connected to the spray nozzle 36, such as by exiting the suction hose 22 via a route through the rod 30 or by a structure forming a fluid path from the rod 30 to the spray nozzle 36. The opposite end 104A of the fluid delivery line 104, closer to the base 12, includes a fluid delivery line fitting 264, which is secured to a first coupling 266 for fluid communication with the fluid pump 106. A valve 268 is disposed within the housing 14 at the first coupling 266 and configured to open when the fitting 264 of the fluid delivery line 104 is coupled to the first coupling 266. The open valve 268 allows fluid from the fluid pump 106 (… Figure 10 The fluid flows through the supply line 270 within the cavity 40 and connected to the fluid pump 106, and flows to the inlet 272 of the valve 268 to provide a pressurized fluid flow to the fluid delivery line 104.

[0081] The suction hose 22 has an inlet 28, as per [reference needed]. Figure 2 As described, the working airflow is drawn through the suction hose 22 via the motor and impeller assemblies 46, 48. The suction hose 22 includes a flexible hose portion 22A (e.g., as shown in the image). Figure 1and Figure 2 (as shown) and hose fitting 22B (as shown) Figure 14 and Figure 15 (As shown) The proximal end of the flexible hose portion 22A is connected to the hose fitting. The hose fitting 22B defines the outlet 274 of the suction hose 22 and is configured to connect to a second connector 280, which is disposed on the base 12 adjacent to the first connector 266. The second connector 280 is in fluid communication with the suction source 44.

[0082] Figure 13 A mounting member 88 is shown, which supports at least a portion of the outer wall 282 of the hose fitting 22B of the suction hose 22 adjacent to and around the outlet 274 of the suction hose 22, as shown. Figure 14 As shown. Mounting member 88 includes an outer portion 88B and an inner portion 88A. The outer portion has a receiving opening 284, and the inner portion receives a fastener 286 that can be inserted into the opening 284, such that mounting portions 88A and 88B together surround the outer periphery of the hose fitting 22B and the outer periphery of the delivery line fitting 264. The outer portion 88B and the inner portion 88A are also referred to as outer mounting portion 88B and inner mounting portion 88A, respectively.

[0083] The bottom wall 300 of the housing 14 of the base 12 includes a platform 302 that extends outward below the fittings 22B, 264 and the mounting 88, as shown below. Figure 13 and Figure 15 The inner mounting portion 88A supports the opening 284 in the outer mounting portion 88B (see [reference]). Figure 15 The mounting member 88 (where two mounting portions 88A, 88B are secured to each other and surround fittings 22B, 264, and fluid delivery line 104 and flexible hose portion 22A are secured to corresponding fittings 264, 22B) is fitted onto platform 302 and abuts against the vertically extending side of housing 14 of base 12 near or adjacent to bottom wall 300. Portion 14A of housing 14 extends laterally outward such that mounting member 88 is partially nested between portion 14A of housing 14, platform 302, and vertically extending side 14B, as shown below. Figure 18 As shown.

[0084] Figure 13 The pivotable latch assembly 304 shown is secured to the outer mounting portion 88B and operable to latch the mounting portion 88 to the base 12. The latch assembly 304 includes a pivotable latch 304A, which pivots in… Figure 16The pivot axis PA shown is pivotally connected to the outer mounting portion 88B. The post 306 extends from the outer mounting portion 88B at the opening 88C in the outer mounting portion 88B and is received in a blind hole 308 of the pivotable latch 304A, as... Figure 18 As shown. The inner side of latch 304A latches to latch receiver 304B located on the outside of base 12 (see...). Figure 15 ).

[0085] Mounting member 88 supports fitting 264 of fluid delivery line 104 and hose fitting 22B of suction hose 22, and appropriately spaces the components so that they can be aligned for connection with corresponding couplings 266, 280. Hose fitting 22B has an opening 310 in the outer wall 282, such as... Figure 14 and Figure 15 As indicated. The fluid delivery line 104 is routed from the first connector 266 and fitting 264 through the mounting member 88 and through the opening 310 in the outer wall 282 of the hose fitting 22B of the suction hose 22, such that the fluid delivery line 104 has a first portion 104B and a second portion 104C, the first portion extending through the mounting member 88 to the opening 310, and the second portion extending inside the suction hose 22 and between the opening 310 and the inlet 28 of the flexible hose portion 22A of the suction hose 22.

[0086] With the first portion 104B exiting the hose fitting 22B at opening 310, the fluid delivery line 104 is thus spaced apart from the outlet 274 of the suction hose 22 (e.g., the outlet 274 of the hose fitting 22B). Keeping the fluid delivery line 104 away from the outlet 274 provides a larger unobstructed area at the outlet 274 (e.g., increasing the flow area through the suction hose 22 at the outlet 274 of the hose fitting 22B) and increases the ability to effectively draw the working airflow through the suction hose 22 and into the recovery tank assembly 20 via the suction source 44.

[0087] Because in Figure 2 During the use of cleaning tool 26 on surface S, both suction hose 22 and fluid delivery line 104 can move in various directions relative to couplings 266, 280 together with cleaning tool 26. Therefore, apart from latch assembly 304, mounting member 88 is configured to be secured to base 12 by utilizing features that reduce torsion and outward movement (e.g., swaying) of mounting member 88 relative to base 12. For example, Figure 15The extraction cleaner 10 is shown, with a first coupling 266 and a second coupling 280 disposed adjacent to each other on a base 12. For clarity, each of the outer mounting portion 88B, the fluid delivery line 104, and the flexible hose portion 22A has been removed. The inner mounting portion 88A has a recessed track 312, which includes a lip 314 having an inner wall 314A, an inclined surface 314B, and an outer wall 314C. The outer mounting portion 88B... Figure 16 and Figure 17 The portion is shown in isolation and includes a protruding rib 318 and a latch 316, which is disposed on the protruding rib 318 and extends inward and latches to the base 12 when the outer mounting portion 88B is secured to the inner mounting portion 88A.

[0088] The outer mounting portion 88B is connected to and mates with the inner mounting portion 88A to at least partially (and, as shown, fully radially surround) fittings 22B and 264. When the outer mounting portion 88B is connected to the inner mounting portion 88A by fastener 286, a protruding rib 318 rests in a recessed track 312. In other words, the protruding rib 318 is shaped and sized to mate with the recessed track 312. A lip 314 interrupts the recessed track 312. A snap 316 is positioned on the outer mounting portion 88B to engage the lip 314 when the protruding rib 318 rests in the recessed track 312.

[0089] The snap 316 slides over the inclined surface 314B of the lip 314 and is engaged with the lip 314 behind the inner wall 314A. The inclined surface 314B is inclined upward and inward in the direction from the outer wall 314C to the inner wall 314A of the lip 314. The engagement and mating of the protruding rib 318 with the recessed track 312, and the engagement and mating of the snap 316 with the lip 314, extend in the directions of the longitudinal central axis LA1 of the hose fitting 22B and the longitudinal central axis LA2 of the fluid delivery line fitting 264, and thus help to limit the outward swing of the mounting member 88 (and the hose fitting 22B, the delivery line fitting 264, the fluid delivery line 104, and the flexible hose portion 22A at the mounting member 88) relative to the base 12.

[0090] In addition to fasteners 286, mating ribs 318 and rails 312, and mating lips 314 and snap fasteners 316, base 12 also has a recess 340. The outer surface 344 of the outer mounting portion 88B of the mounting member 88 is shaped to fit into the recess 340 to restrict movement of the mounting member 88 relative to base 12. More specifically, as Figure 15As shown, the base 12 has a wall 342 at the recess 340, which is angled relative to the longitudinal central axis LA1 of the second connector 280 (which is the same as the longitudinal central axis LA1 of the hose fitting 22B). The outer surface 344 of the outer mounting portion 88B defines a bevel 346 (see...). Figure 16 The ramp abuts against the wall 342 of the base 12 to help prevent the mounting 88 (and the hose fitting 22B, delivery line fitting 264, fluid delivery line 104 and flexible hose portion 22A at the mounting 88) from swaying upward relative to the base 12.

[0091] Furthermore, the base 12 includes an inner surface 348, and the outer mounting portion 88B defines a wall 350 that is inside the inner surface 348 and just inside the recess 340 (e.g., forward) and mates with the outer side of fittings 22B, 264 (see [link]). Figure 15 and Figure 18 The inner surface 348 of the housing 14 inside the recess 340 (e.g., forward) is... Figure 15 The arrow is partially hidden in the middle. Wall 350 is... Figure 13 The location inside the housing 14 is indicated by a hidden line. Figure 18 A wall 350 is shown located inside and adjacent to the inner surface 348 of the housing 14, the inner surface of the housing being outside the fittings 22B, 264.

[0092] The inner surface 348 of the housing 14 abuts against the wall 350 to limit the outward swinging of the mounting member 88 (and the hose fitting 22B, delivery line fitting 264, fluid delivery line 104, and flexible hose portion 22A at the mounting member 88) relative to the base 12. In fact, the engagement of the snaps 316 and lips 314 below the fittings 22B, 264, and the abutment of the wall 350 above and outside the fittings 22B, 264, and the inner surface 348 of the housing 14, along with multiple features spaced apart from each other around the fittings 22B, 264, restricts or prevents the torsion of the mounting member 88 (and the hose fitting 22B, delivery line fitting 264, fluid delivery line 104, and flexible hose portion 22A at the mounting member 88) relative to the base 12 due to movement of the flexible hose portion 22A during use of the extractor cleaner 10. In other words, the interlocking features that restrict or prevent torsion include a fastener 286 that mates with the fastener opening 284, a lip 314 that mates with the snap 316, and a wall 350 that mates with the inner surface 348 of the housing 14. Each of these feature pairs is angularly spaced from each other around the longitudinal central axes LA1, LA2 of fittings 22B, 264 to support the mounting 88 (and the hose fitting 22B, delivery line fitting 264, fluid delivery line 104, and flexible hose portion 22A at the mounting 88) relative to the base 12.

[0093] The use of this device offers various advantages. Therefore, the extraction cleaner 10 achieves a compact design, fully utilizing the handle 16 to help support the supply tank assembly 18 and the recovery tank assembly 20, and integrating the latch assembly 220 into the base 12, such as at the handle 16. The structure of the lifting handle 16 of the extraction cleaner 10 allows for a higher recovery tank 110 and supply tank 154, thus providing tank volume without increasing the width of the base 12. The mounting member 88 helps ensure that the suction hose 22 and fluid delivery line 104 remain connected to the base 12, while reducing swaying and twisting of the suction hose 22 and fluid delivery line 104 relative to the base 12. Furthermore, effective cooling of the battery pack 56 and PCBA 58 is achieved by placing the battery pack 56 above the cooling fan 246 and adjacent to the air inlet 124, and by utilizing the cooling space 260 provided between the multiple walls of the housing 14 and the battery pack 56 to largely surround the battery pack 56. It can achieve and / or obtain additional benefits and advantages.
