RT-89CHARGING AND CLEANING UNIT FOR POOL CLEANING ROBOTS CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application No. 63 / 700,741, titled CHARGING UNIT AND OUT OF WATER SENSOR, filed September 29, 2024, which is hereby incorporated by reference in its entirety.FIELD OF INVENTION

[0002] The present disclosure relates to charging systems for pool cleaning robots, and more particularly to a charging and cleaning unit with conductive cleaning elements that perform contact-based cleaning of charged interface elements while providing electrical charging functionality.BACKGROUND

[0003] Pool cleaning robots have become increasingly popular for maintaining swimming pools, as they provide automated cleaning without requiring manual intervention. These robotic devices operate by moving through the pool water while collecting debris and cleaning surfaces. To function effectively, pool cleaning robots require reliable power sources that can be recharged when the robot is not in use.

[0004] Charging systems for pool cleaning robots face particular challenges due to the aquatic environment in which these devices operate. The robots are regularly submerged in pool water, which can contain various chemicals, debris, and contaminants. When the robots are removed from the pool for charging, their electrical contacts and interfaces may be covered with dirt, algae, and other residues that accumulate during operation.

[0005] Traditional charging interfaces for electronic devices typically rely on clean, dry contact surfaces to establish proper electrical connections. However, pool cleaning robots present a different scenario where the charging contacts may be contaminated with pool water residues. This contamination can interfere with the charging process and may lead to poor electrical connections or charging failures.

[0006] Pool cleaning robots may also incorporate sensors to detect when they are out of water, which helps prevent damage that could occur if the robot operates outside of its intended aquatic environment. These sensors often include multiple pins or electrodes that are exposed to the pool environment during operation. Like the charging contacts,RT-89 these sensor elements can accumulate dirt and algae over time, which may affect their performance and reliability.

[0007] The maintenance of both charging contacts and sensor elements presents ongoing challenges for pool cleaning robot systems. Users may need to manually clean these components to maintain proper functionality, which adds to the maintenance requirements of the system. Additionally, the design of charging and sensing interfaces for pool cleaning robots involves considerations for water drainage, contamination resistance, and reliable electrical connections in environments where moisture and debris are common factors.

[0008] There is a general need for improved charging and interface systems for pool cleaning robots that can address the challenges associated with contaminated contacts and sensor elements while providing reliable electrical connections and sensing capabilities.SUMMARY

[0039] The following description sets forth exemplary aspects of the present disclosure. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure. Rather, the description also encompasses combinations and modifications to those exemplary aspects described herein.

[0040] Pool cleaning robots operate in challenging aquatic environments where electrical connections may become contaminated with debris, algae, and other pool contaminants during normal operation. Traditional charging systems for such robots typically focus solely on power transfer, leaving contaminated electrical contacts to degrade over time and potentially compromise charging efficiency. The present disclosure addresses these challenges through a dual-function approach that combines electrical charging capabilities with active cleaning functionality in a single integrated system.

[0041] The charging and cleaning system described herein provides simultaneous power delivery and contact maintenance for pool cleaning robot interfaces. In some cases, the system may include complementary interface components that work together to establish electrical connections while mechanically removing contaminants from contact surfaces. The cleaning action may occur through direct physical contact between conductive elements, where the mechanical engagement serves both to establish electrical pathways and to scrub away accumulated debris.

[0042] In some cases, the system may incorporate multiple conductive elements arranged to provide both charging functionality and non-charging cleaning functionality. Some conductive elements may be electrically coupled to power delivery circuits, while other conductive elements may serve purely mechanical cleaning roles without carryingRT-89 charging current. This arrangement allows for comprehensive contact cleaning while maintaining electrical isolation between different functional zones of the interface.

[0043] The dual-function approach may provide particular advantages in pool environments where electrical contacts are regularly exposed to water, chemicals, and organic matter. In some cases, the cleaning action may help maintain low-resistance electrical connections over extended periods of use, potentially reducing maintenance requirements and improving charging reliability. The mechanical cleaning process may remove both conductive and non-conductive contaminants that could otherwise interfere with proper electrical contact or create unwanted current paths.

[0044] A kit configuration may bring together the complementary components needed for both charging and cleaning operations. In some cases, such a kit may include interface components designed to mate with each other, where one component provides the cleaning and charging elements while the corresponding component presents the surfaces to be cleaned and charged. The kit approach may facilitate manufacturing, distribution, and field replacement of system components while ensuring compatibility between mating interfaces.

[0045] Referring to FIG. 1, a charged interface 10 may be configured to receive electrical power and provide sensing functionality for pool cleaning robot applications. The charged interface 10 may include an interface body 34 that houses and supports various electrical components. In some cases, the interface body 34 may provide structural integrity and environmental protection for internal electrical elements while facilitating proper alignment with corresponding charging equipment. The charged interface 10 may be configured as a female connector that receives a mating male connector during charging and cleaning operations.

[0046] The charged interface 10 may include a set of charging interface elements arranged within the interface body 34. As shown in FIG. 1, the set may include a first charging interface element 11, a second charging interface element 12, a third charging interface element 13, and a fourth charging interface element 14. In some cases, these charging interface elements may be positioned in a linear arrangement across the interface body 34, providing multiple contact points for electrical connection and sensing operations. The first charging interface element 11 through the fourth charging interfaceRT-89 element 14 may be spaced apart from each other to prevent unwanted electrical contact while maintaining proper functionality.

[0047] The set of charging interface elements may include different functional subsets to support various operational requirements. In some cases, the set may include a subset of capacitive charged elements and a subset of sensing elements. The subset of capacitive charged elements may include two capacitive charged elements that facilitate power transfer during charging operations. The subset of sensing elements may include two sensing elements that provide monitoring and detection capabilities. In some cases, the two capacitive charged elements may correspond to two of the charging interface elements, while the two sensing elements may correspond to the remaining two charging interface elements.

[0048] With continued reference to FIG. 1, the two sensing elements may function as electrodes of an out of water sensor system. The out of water sensor may detect when the pool cleaning robot has been removed from water, which may trigger specific operational responses such as shutdown procedures or charging readiness states. In some cases, the sensing elements may monitor electrical conductivity or resistance between contact points to determine the presence or absence of water. The first charging interface element 11 and the second charging interface element 12 may serve as the two sensing elements, while the third charging interface element 13 and the fourth charging interface element 14 may serve as the two capacitive charged elements, or the functional assignments may be arranged in alternative configurations.

[0049] FIG. 1 further illustrates a set of cleaning elements that includes a first cleaning element 111, a second cleaning element 112, a third cleaning element 113, and a fourth cleaning element 114. In some cases, these cleaning elements may be positioned in a linear arrangement that corresponds to the positioning of the first charging interface element 11, second charging interface element 12, third charging interface element 13, and fourth charging interface element 14 of the charged interface 10.

[0050] As further shown in FIG. 2, the charging interface elements may be positioned to align with corresponding cleaning elements of a mating charging interface. The interface body 34 may provide precise positioning and spacing for the first charging interface element 11, second charging interface element 12, third charging interfaceelement 13, and fourth charging interface element 14 to ensure proper electrical contact during mating operations. In some cases, the interface body 34 may include alignment features or guide structures that facilitate proper insertion and connection with the charging and cleaning interface. The female connector configuration of the charged interface 10 may allow the charging interface elements to be recessed within the interface body 34, providing protection from environmental contamination when not connected to charging equipment.

[0051] Referring to FIG. 3, a charging interface 110 may be configured to provide both electrical charging and mechanical cleaning functionality for pool cleaning robot applications. The charging interface 110 may include a charging body 160 that has an electrically insulating exterior to prevent unwanted electrical contact between internal conductive elements and external surfaces. In some cases, the charging body 160 may provide structural support and environmental protection for internal electrical components while maintaining proper electrical isolation. The charging interface 110 may be configured as a male connector that mates with the charged interface 10 during charging and cleaning operations.

[0052] The charging interface 110 may include a set of cleaning elements arranged within the charging body 160 to provide comprehensive contact cleaning and electrical connection capabilities. As shown in FIG. 3, the set of cleaning elements may include a first cleaning element 111, a second cleaning element 112, a third cleaning element 113, and a fourth cleaning element 114. In some cases, these cleaning elements may be positioned in a linear arrangement that corresponds to the positioning of the first charging interface element 11, second charging interface element 12, third charging interface element 13, and fourth charging interface element 14 of the charged interface 10. Each cleaning element may be electrically conductive and may be configured to perform contact-based cleaning of an element of the charged interface 10 that contacts the cleaning element during mating operations.

[0053] The set of cleaning elements may be organized into functional subsets to support different operational requirements. In some cases, the set of cleaning elements may include a conductive charging subset of cleaning elements and a non-charging subset of cleaning elements. The conductive charging subset of cleaning elements may includecleaning elements that are electrically coupled to power delivery circuits and actively participate in charging operations. The non-charging subset of cleaning elements may include cleaning elements that provide mechanical cleaning functionality without carrying charging current, thereby maintaining electrical isolation while contributing to contact maintenance.

[0054] With continued reference to FIG. 3, the conductive charging subset of cleaning elements may include a positive cleaning element and a non-positive cleaning element to facilitate power transfer during charging operations. In some cases, the positive cleaning element may be electrically coupled to a positive wire of the charging interface 110, while the non-positive cleaning element may be electrically coupled to a non-positive wire of the charging interface 110. The first cleaning element 111 may serve as the positive cleaning element, while the fourth cleaning element 114 may serve as the non-positive cleaning element, providing the electrical pathways for power delivery to the charged interface 10. A first conductor 126 and a second conductor 127 may provide the electrical connections between the cleaning elements and an interface cable 130 that carries power and control signals to and from the charging interface 110.

[0055] The non-charging subset may include cleaning elements positioned to provide comprehensive contact cleaning without participating in power transfer operations. In some cases, the non-charging subset may include a first non-charging cleaning element that is positioned between the positive cleaning element and the non-positive cleaning element. The second cleaning element 112 may serve as the first non-charging cleaning element, positioned between the first cleaning element 111 and the fourth cleaning element 114 to provide cleaning functionality for the second charging interface element 12 of the charged interface 10. The non-charging subset may also include a second noncharging cleaning element that is positioned to a side of the subset of cleaning elements. The third cleaning element 113 may serve as the second non-charging cleaning element, positioned adjacent to other cleaning elements to provide cleaning functionality for the third charging interface element 13.

[0056] As further shown in FIG. 3, the set of conductive elements may include alternating charging cleaning elements and non-charging elements to provide balanced functionality across the interface. The alternating arrangement may help maintain properelectrical isolation between power-carrying elements while ensuring comprehensive cleaning coverage for all contact surfaces of the charged interface 10. In some cases, the first cleaning element 111 may serve as a charging cleaning element, the second cleaning element 112 may serve as a non-charging element, the third cleaning element 113 may serve as a non-charging element, and the fourth cleaning element 114 may serve as a charging cleaning element. This alternating configuration may help prevent unwanted electrical contact between power-carrying elements while providing mechanical cleaning for all charging interface elements of the charged interface 10.

[0057] Each cleaning element of the charging interface 110 may include a segmented construction that facilitates both electrical contact and mechanical cleaning operations. In some cases, each cleaning element may include a first group of conductive segments and a second group of conductive segments that face each other to provide comprehensive contact engagement. The first group and the second group may be positioned to create a contact interface that can accommodate the charging interface elements of the charged interface 10 while providing cleaning action through mechanical engagement. The segmented arrangement may allow for controlled deflection and contact pressure during mating operations, which may enhance both electrical connectivity and debris removal effectiveness.

[0058] The first group may contact the second group in a configuration that maintains structural integrity while allowing for operational flexibility. In some cases, the contact between the first group and the second group may provide a spring-like action that maintains consistent contact pressure against the charging interface elements during cleaning and charging operations. The contact arrangement may also help distribute mechanical stresses across the cleaning element structure, potentially reducing wear and extending operational life. The first group and second group may be fabricated from conductive materials that provide both electrical conductivity and mechanical durability for repeated mating cycles.

[0059] Each group of the first and second groups may include multiple segment types arranged to provide specific functional characteristics during engagement operations. In some cases, each group may include an inward oriented proximal segment, an intermediate segment, and an outward oriented distal segment that work together toRT-89 guide and clean the charging interface elements. The inward oriented proximal segment may be positioned closest to the charging body 160 and may provide structural anchoring for the cleaning element. The intermediate segment may be positioned between the proximal and distal segments and may provide the primary contact surface for electrical connection and cleaning action. The outward oriented distal segment may be positioned furthest from the charging body 160 and may provide initial contact and guidance during mating operations.

[0060] The first cleaning element 111 may include a segmented structure that incorporates the multi-segment design across both groups of conductive segments. In some cases, the first cleaning element 111 may include a first distal segment 111-1 and a second distal segment 111-2 that serve as the outward oriented distal segments for the first group and second group respectively. The first cleaning element 111 may also include a first intermediate segment 111-3 and a second intermediate segment 111-4 that provide the primary contact surfaces for electrical and mechanical engagement. A first proximal segment 111-5 and a second proximal segment 111-6 may serve as the inward oriented proximal segments that anchor the first cleaning element 111 to the charging body 160. The segmented construction may allow the first cleaning element 111 to flex and conform to the first charging interface element 11 during mating operations while maintaining consistent electrical contact.

[0061] The second cleaning element 112 may incorporate a similar segmented arrangement to provide cleaning functionality for the second charging interface element 12. In some cases, the second cleaning element 112 may include a third distal segment 112-1 and a fourth distal segment 112-2 that function as the outward oriented distal segments for the respective groups of conductive segments. A third intermediate segment 112-3 and a fourth intermediate segment 112-4 may provide the contact surfaces for engagement with the second charging interface element 12. The second cleaning element 112 may also include a third proximal segment 112-5 and a fourth proximal segment 112- 6 that anchor the cleaning element to the charging body 160. The segmented structure may enable the second cleaning element 112 to provide mechanical cleaning action while maintaining proper electrical isolation from adjacent cleaning elements.RT-89

[0062] The third cleaning element 113 may feature a segmented construction that supports its role in the non-charging subset of cleaning elements. In some cases, the third cleaning element 113 may include a fifth distal segment 113-1 and a sixth distal segment113-2 that serve as the initial contact points during mating operations. A fifth intermediate segment 113-3 and a sixth intermediate segment 113-4 may provide the primary cleaning surfaces that engage with the third charging interface element 13. The third cleaning element 113 may also include a fifth proximal segment 113-5 and a sixth proximal segment 113-6 that provide structural support and anchoring to the charging body 160. The segmented design may allow the third cleaning element 113 to provide effective mechanical cleaning without participating in electrical power transfer operations.

[0063] The fourth cleaning element 114 may incorporate the segmented structure to support both cleaning and charging functionality. In some cases, the fourth cleaning element 114 may include a seventh distal segment 114-1 and an eighth distal segment114-2 that provide initial contact and guidance during engagement with the fourth charging interface element 14. A seventh intermediate segment 114-3 and an eighth intermediate segment 114-4 may serve as the primary contact surfaces for both electrical connection and mechanical cleaning. The fourth cleaning element 114 may also include a seventh proximal segment 114-5 and an eighth proximal segment 114-6 that anchor the cleaning element to the charging body 160 and may provide electrical connection to the second conductor 127 through the interface cable 130. The segmented arrangement may enable the fourth cleaning element 114 to maintain consistent electrical contact while providing cleaning action.

[0064] The intermediate segments of the first and second groups may be parallel to each other to provide consistent contact geometry and cleaning effectiveness. In some cases, the parallel arrangement of the intermediate segments may create a uniform contact zone that engages with the charging interface elements along their length during mating operations. The first intermediate segment 111-3 and the second intermediate segment 111-4 of the first cleaning element 111 may be positioned parallel to each other to provide balanced contact with the first charging interface element 11. Similarly, the third intermediate segment 112-3 and the fourth intermediate segment 112-4 may beRT-89 parallel to each other, the fifth intermediate segment 113-3 and the sixth intermediate segment 113-4 may be parallel to each other, and the seventh intermediate segment 114-3 and the eighth intermediate segment 114-4 may be parallel to each other. The parallel configuration may help distribute contact forces evenly and may provide consistent cleaning action across the width of each charging interface element.

[0065] Referring to FIG. 4 and FIG. 4A, the manufacturing process for the charged interface 10 may involve multiple sequential stages that establish the electrical and structural components needed for charging and sensing operations. The manufacturing process may begin with the placement and positioning of conductor terminals that provide electrical connection points for the charging interface elements. In some cases, a first conductor terminal 21, a second conductor terminal 22, a third conductor terminal 23, and a fourth conductor terminal 24 may be positioned to correspond with the first charging interface element 11, the second charging interface element 12, the third charging interface element 13, and the fourth charging interface element 14 respectively. The conductor terminals may be fabricated from conductive materials that provide reliable electrical connectivity while maintaining structural integrity during subsequent manufacturing operations. An injected base 25 may provide structural support and positioning for the charging interface elements and conductor terminals during the assembly process.

[0066] The conductor terminals may be arranged in a linear configuration that matches the intended spacing and alignment of the charging interface elements within the interface body 34. In some cases, the first conductor terminal 21 through the fourth conductor terminal 24 may be positioned at predetermined intervals to ensure proper electrical isolation between adjacent terminals while maintaining compatibility with the charging interface 110 during mating operations. The injected base 25 may include positioning features or alignment structures that maintain the precise location of each conductor terminal during subsequent manufacturing steps. The conductor terminals may extend from the injected base 25 in a direction that facilitates electrical connection with internal conductors while providing accessible contact surfaces for the charging interface elements.RT-89

[0067] As further shown in FIG. 4 and FIG. 4A, the manufacturing process may continue with the installation of internal conductors that provide electrical pathways between the conductor terminals and external connection points. A first conductor 26, a second conductor 27, a third conductor 28, and a fourth conductor 29 may be connected to the first conductor terminal 21, the second conductor terminal 22, the third conductor terminal 23, and the fourth conductor terminal 24 respectively to establish electrical continuity throughout the charged interface 10. The conductors may be fabricated from materials that provide low electrical resistance and mechanical flexibility to accommodate the structural requirements of the interface body 34. In some cases, the first conductor 26 through the fourth conductor 29 may extend from their respective conductor terminals toward external connection points that interface with pool cleaning robot electrical systems.

[0068] The conductor installation process may involve precise routing and positioning to maintain electrical isolation between different conductors while providing reliable connectivity for charging and sensing operations. In some cases, the first conductor 26 and the fourth conductor 29 may be routed to support the capacitive charged elements functionality, while the second conductor 27 and the third conductor 28 may be routed to support the sensing elements functionality. The conductors may be secured within the injected base 25 through mechanical retention features or adhesive bonding to prevent movement during subsequent manufacturing operations. The conductor routing may also accommodate the dimensional requirements of the interface body 34 while maintaining proper spacing between adjacent electrical pathways.

[0069] With continued reference to FIG. 4 and FIG. 4A, the manufacturing process may proceed with injection molding operations that encapsulate the electrical components within protective housing materials. A polypropylene portion 32 may be formed around the conductor terminals and portions of the conductors to provide structural integrity and environmental protection for the internal electrical components. The polypropylene portion 32 may be injection molded using techniques that maintain the precise positioning of the conductor terminals while creating a unified structural foundation for the charged interface 10. In some cases, the polypropylene portion 32 may include features that facilitate proper alignment and mating with the charging interfaceRT-89110 during charging operations. The injection molding process may be controlled to ensure that the conductor terminals remain accessible for electrical contact while being securely retained within the polypropylene portion 32.

[0070] Referring to FIG. 4 A and FIG. 4 A, the manufacturing process may include additional injection molding stages that provide enhanced environmental protection and sealing capabilities for the charged interface 10. A thermoplastic elastomer portion 33 may be formed around the polypropylene portion 32 to create a multi-layer construction that combines structural strength with flexible sealing properties. The thermoplastic elastomer portion 33 may surround the polypropylene portion 32 in a configuration that provides ingress protection against water, debris, and other environmental contaminants commonly encountered in pool cleaning applications. In some cases, the thermoplastic elastomer portion 33 may extend beyond the boundaries of the polypropylene portion 32 to create sealing surfaces that engage with corresponding features of the charging interface 110 during mating operations.

[0071] The first conductor 26, the second conductor 27, the third conductor 28, and the fourth conductor 29 may be positioned within the multi-layer construction to maintain electrical isolation while providing reliable connectivity to their respective charging interface elements. In some cases, the conductors may include electrical conductor coated with one or more insulating layers to provide additional protection against electrical shorts or unwanted current paths. The insulating layers may be applied to the conductors before or during the injection molding process to ensure comprehensive electrical isolation throughout the charged interface 10. The thermoplastic elastomer portion 33 may be formulated to provide chemical resistance against pool chemicals and cleaning agents while maintaining flexibility over the operational temperature range of pool cleaning robots. The multi-layer construction created by the polypropylene portion 32 and the thermoplastic elastomer portion 33 may provide a high ingress protection grade that prevents water infiltration and maintains electrical integrity during submerged operations.

[0072] Referring to FIG. 5 and FIG. 5A, the manufacturing process for the charging interface 110 may involve sequential stages that establish the structural and electrical components needed for both charging and cleaning operations. The manufacturingRT-89 process may begin with the formation of an injected base 125 that provides structural support and positioning for the cleaning elements during assembly operations. In some cases, the injected base 125 may be fabricated from materials that provide dimensional stability and mechanical strength while facilitating subsequent injection molding operations. The injected base 125 may include positioning features or alignment structures that maintain the precise location of each cleaning element during the manufacturing process. The first cleaning element 111, the second cleaning element 112, the third cleaning element 113, and the fourth cleaning element 114 may be positioned within or upon the injected base 125 in a configuration that matches the intended spacing and alignment for mating with the charged interface 10.

[0073] The cleaning elements may be arranged within the injected base 125 to provide proper electrical connectivity and mechanical functionality for both charging and cleaning operations. In some cases, the first cleaning element 111 and the fourth cleaning element 114 may be electrically connected to power delivery circuits through the first conductor 126 and the second conductor 127 respectively. The second cleaning element 112 and the third cleaning element 113 may be positioned to provide mechanical cleaning functionality without direct electrical connection to charging circuits, thereby maintaining electrical isolation while contributing to contact maintenance operations. The interface cable 130 may be connected to the first conductor 126 and the second conductor 127 to provide electrical pathways between the charging interface 110 and external power sources or control systems. The injected base 125 may accommodate the routing of the first conductor 126, the second conductor 127, and the interface cable 130 while maintaining proper spacing between conductive elements to prevent unwanted electrical contact.

[0074] With continued reference to FIG. 5 and FIG. 5A, the manufacturing process may incorporate precise positioning and retention of the cleaning elements to ensure consistent performance during mating operations with the charged interface 10. The first cleaning element 111 through the fourth cleaning element 114 may be secured within the injected base 125 through mechanical retention features, adhesive bonding, or integrated molding techniques that prevent movement during subsequent manufacturing operations. In some cases, the cleaning elements may be positioned to maintain the segmentedRT-89 structure that includes the proximal segments, intermediate segments, and distal segments that facilitate both electrical contact and mechanical cleaning. The injected base 125 may include features that support the proper orientation and spacing of these segments to ensure effective engagement with the first charging interface element 11, the second charging interface element 12, the third charging interface element 13, and the fourth charging interface element 14 during charging operations. The manufacturing process may also incorporate quality control measures to verify the electrical connectivity and mechanical alignment of each cleaning element before proceeding to subsequent molding stages.

[0075] Referring to FIG. 5 and FIG. 5A, the manufacturing process may continue with injection molding operations that create the multi-layer construction of the charging body 160 for enhanced structural integrity and environmental protection. A polypropylene portion 132 may be formed around the injected base 125 and portions of the cleaning elements to provide a rigid structural foundation for the charging interface 110. The polypropylene portion 132 may be injection molded using controlled temperature and pressure parameters that maintain the precise positioning of the cleaning elements while creating a unified structural base. In some cases, the polypropylene portion 132 may include features that facilitate proper alignment and mating with the charged interface 10 during charging operations while providing mechanical protection for internal electrical components.
