Patent Description:
The present invention relates to the field of pool cleaners, and in particular to a pool cleaner having a rotatable and releasable hose assembly, and to methods of using the same.

A pool cleaner may be equipped with a hydraulic driving assembly. In operation, a flexible water inlet hose may direct water to the hydraulic driving assembly to drive the pool cleaner back and forth across the pool. It may be desirable for the water inlet hose to move relative to a housing of the pool cleaner to avoid entanglement during this back and forth movement. However, providing such movement relative to the housing may inhibit installation and/or removal of the water inlet hose.

<CIT> describes a fluid distribution system for an underwater pool cleaner. The pool cleaner comprises an inlet body having an inlet for receiving a supply of pressurized fluid, a valve assembly body in fluid communication with the inlet of the inlet body and including a plurality of fluid outlets, a first one of the outlets providing fluid for propelling the underwater pool cleaner in a forward direction and a second one of the outlets providing fluid for propelling the underwater pool cleaner in a reverse direction, and a valve subassembly including a cam wheel that is fluidically driven by the supply of pressurized fluid and periodically switches the supply of pressurized fluid from the first one of the outlets to the second one of the outlets to periodically change direction of propulsion of the underwater pool cleaner.

In particular, the pool cleaner of <CIT> comprises a rear wall having an inlet port. The pool cleaner also comprises a segmented hose. The pool cleaner also comprises a drive assembly and water distribution manifold in fluid communication with one another. The pool cleaner also comprises wheels coupled to the drive assembly. The inlet port includes an external nozzle to allow the segmented hose to be connected to the pool cleaner. The inlet port includes an internal nozzle in fluid communication with the external nozzle and with the drive assembly.

<CIT> describes a pool cleaner comprising a drive reversing mechanism. The drive reversing mechanism is for driving a running wheel of a pool cleaner and comprises: an inlet pipe, an outlet pipe, an impeller, and a driving reversing gear set; the inlet pipe and the outlet pipe being connected to each other.

<CIT> describes a pool cleaner for use in a pool. The pool cleaner includes a housing, a hydraulic driving assembly disposed within the housing, a filtration assembly disposed within the housing, one or more traction assemblies, and a transmission assembly that operatively couples the hydraulic driving assembly to the traction assemblies.

The present disclosure provides a pool cleaner equipped with a joint and a water inlet hose. In a rotatable or use configuration, the water inlet hose is freely rotatable relative to a housing to avoid entanglement. In a locked or non-use configuration, either the joint or the water inlet hose is fixed relative to the housing to facilitate installation and/or removal of the water inlet hose via rotation between the joint and the water inlet hose.

According to an exemplary embodiment of the present disclosure, a pool cleaner configured to clean a pool is disclosed, the pool cleaner including a housing having a through-hole, a flexible water inlet hose, a hydraulic driving assembly including a water inlet, at least one traction assembly operably coupled to the driving assembly, and a joint extending through the through-hole of the housing and including an upper end in fluid communication with the water inlet hose and a lower end in fluid communication with the water inlet. The pool cleaner has a rotatable configuration in which the flexible water inlet hose and the joint are coupled together and rotatable together relative to the housing, and a locked configuration in which one of the joint and the water inlet hose is a locked component that is restricted from rotating relative to the housing and the other of the joint and the water inlet hose is a rotatable component that is rotatable relative to the housing, wherein the joint and the water inlet hose are selectively coupled together via rotation of the rotatable component relative to the locked component in the locked configuration.

In certain embodiments, the joint floats upward in the housing in the rotatable configuration and falls downward in the housing due to gravity in the locked configuration.

The mounting rib of the joint may include a locking protrusion, and the mounting hole of the water inlet hose may include a locking recess that receives the locking protrusion to secure the joint and the water inlet hose together.

In certain embodiments, the water inlet hose is the locked component and the joint is the rotatable component in the locked configuration. The pool cleaner may further include a rotary sleeve coupled to the joint and configured to rotate the joint relative to the water inlet hose in the locked configuration. The rotary sleeve may be positioned atop the housing.

In certain embodiments, the water inlet hose and the joint are threaded together.

In certain embodiments, the pool cleaner further includes a bearing positioned between the joint and the housing.

The joint has a rotatable configuration in which the lower end of the joint is rotatable relative to the water inlet, and a locked configuration in which the lower end of the joint is restricted from rotating relative to the water inlet and the water inlet hose is rotatable relative to the upper end of the joint.

In certain embodiments, the water inlet includes at least one locking protrusion and the joint includes at least one locking slot. In the rotatable configuration, the at least one locking slot floats above the at least one locking protrusion. In the locked configuration, the at least one locking slot moves downward and engages the at least one locking protrusion.

According to another exemplary embodiment of the present disclosure, a method of using a pool cleaner is disclosed. The pool cleaner has a housing, a hydraulic driving assembly with a water inlet, and a joint. The method includes the steps of moving the pool cleaner across a pool by directing water from a water inlet hose, through the joint, and through the water inlet of the hydraulic driving assembly, wherein the joint and the water inlet hose rotate together relative to the water inlet during the moving step, and removing the water inlet hose by restricting rotation of the joint relative to the housing and rotating the water inlet hose relative to the housing and the joint.

In certain embodiments, the method further includes installing the water inlet hose by restricting rotation of the joint relative to the housing and rotating the water inlet hose relative to the housing and the joint in an opposite direction as the removing step.

In certain embodiments, the joint floats upward during the moving step and moves downward to engage the water inlet during the removing step.

According to yet another exemplary embodiment of the present disclosure, a method of using a pool cleaner is disclosed.

The above-mentioned and other features and advantages of this disclosure, and the manner of attaining them, will become more apparent and will be better understood by reference to the following description of embodiments of the invention taken in conjunction with the accompanying drawings, wherein:.

Corresponding reference characters indicate corresponding parts throughout the several views. The exemplifications set out herein illustrate exemplary embodiments of the invention and such exemplifications are not to be construed as limiting the scope of the invention in any manner. The scope of the invention is solely limited by the appended claims.

<FIG> provides a first embodiment of a pool cleaner <NUM> configured to clean a floor and/or sidewalls of a pool. The pool cleaner <NUM> includes a housing <NUM> that defines a through-hole <NUM> in its upper surface. The pool cleaner <NUM> also includes a hydraulic driving assembly <NUM> including a water inlet <NUM> adjacent to the through-hole <NUM>, a water outlet <NUM>, and an impeller <NUM> disposed within the housing <NUM> and in fluid communication between the water inlet <NUM> and the water outlet <NUM>. The pool cleaner <NUM> also includes a filtration assembly <NUM> disposed within the housing <NUM> to collect debris. The pool cleaner <NUM> further includes a transmission assembly <NUM> operably coupled to the driving assembly <NUM> and including a plurality of gears. The pool cleaner <NUM> further includes one or more wheels <NUM> or other traction assemblies (e.g., tracks) and one or more brush assemblies <NUM> operably coupled to the transmission assembly <NUM>.

The pool cleaner <NUM> also includes a joint <NUM> configured to receive a flexible water inlet hose <NUM>, illustratively a corrugated hose. The joint <NUM> passes through the through-hole <NUM> of the housing <NUM>. A lower end <NUM> of the joint <NUM> has a rotatable or use configuration and a locked or non-use configuration relative to the housing <NUM> and the water inlet <NUM>. An upper end <NUM> of the joint <NUM> is removably coupled to the water inlet hose <NUM> via rotation. In this way, the rotatable configuration of the joint <NUM> allows the water inlet hose <NUM> to rotate relative to the housing <NUM> during use, and the locked configuration of the joint <NUM> facilitates installation and/or removal of the water inlet hose <NUM> via rotation when not in use. The joint <NUM> and its operation are described further below.

When the pool cleaner <NUM> is in use, water is directed through a waterway including the water inlet hose <NUM>, the joint <NUM>, and the water inlet <NUM>, across the impeller <NUM>, and out of the water outlet <NUM>, which rotates the impeller <NUM>. The rotation of the impeller <NUM> is transferred to the brush assembly <NUM> via the transmission assembly <NUM>, which causes the brush assembly <NUM> to rotate and direct debris into the filtration assembly <NUM>. The rotation of the impeller <NUM> is also transferred to the wheels <NUM> via the transmission assembly <NUM>, which causes the pool cleaner <NUM> to drive back and forth across the pool. With the joint <NUM> in the rotatable configuration, the water inlet hose <NUM> is able to rotate freely relative to the housing <NUM> and the water inlet <NUM> during this back and forth movement, thus avoiding entangling of the water inlet hose <NUM>.

The driving assembly <NUM> is shown in <FIG>. The water inlet <NUM> of the driving assembly <NUM> includes a cylindrical side wall <NUM>, one or more rotation-locking protrusions <NUM> protruding radially inward from the side wall <NUM>, a base or flange <NUM> extending radially inward from the bottom of the side wall <NUM> (See also <FIG>), and an annular retaining wall <NUM> that extends upward from the base <NUM> in a direction parallel to the side wall <NUM> and at a location radially inward of the side wall <NUM>.

The joint <NUM> is shown in <FIG>. The joint <NUM> is a tubular structure including a generally cylindrical side wall <NUM> that extends between the lower end <NUM> and the upper end <NUM>. A flange <NUM> extends radially outward from the side wall <NUM> and includes one or more rotation-locking slots <NUM> positioned along the perimeter of the flange <NUM>. Below the flange <NUM>, a foot <NUM> extends radially outward from the lower end <NUM> of the side wall <NUM>. The flange <NUM> and the foot <NUM> cooperate to define a groove <NUM> configured to receive a seal <NUM> (e.g., a V-ring) (<FIG>). Above the flange <NUM>, the joint <NUM> is configured to support a thrust bearing <NUM> (<FIG>). The joint <NUM> also includes a mounting rib <NUM> that protrudes outward from the side wall <NUM> in a circumferential direction and then bends axially at one end to form a stop <NUM>. One or more locking protrusions <NUM> protrude axially from the mounting rib <NUM>.

The water inlet hose <NUM> is shown in <FIG>. A coupling <NUM> is coupled (e.g., screwed, welded, adhered) to a distal end of the water inlet hose <NUM>. The coupling <NUM> includes a cylindrical side wall <NUM> with a mounting hole <NUM> that extends through the side wall <NUM> in a circumferential direction. One or more locking recesses <NUM> extend axially into the mounting hole <NUM>. Along the inner surface of the cylindrical side wall <NUM>, the coupling <NUM> also includes a mounting groove <NUM> that is open at its lower end and includes a side notch <NUM> that communicates with the mounting hole <NUM> (See also <FIG>).

The operation of the joint <NUM> will now be described with reference to <FIG>.

In <FIG>, the joint <NUM> is shown in the rotatable or use configuration, in which the joint <NUM> is positioned in the pool and floats upward in the water. The flange <NUM> of the joint <NUM> is located below the through-hole <NUM> of the housing <NUM> and has an outer diameter larger than an inner diameter of the through-hole <NUM>, thereby limiting upward movement of the joint <NUM> in the housing <NUM> and preventing detachment of the joint <NUM> from the housing <NUM>. In this rotatable configuration, the rotation-locking slots <NUM> on the flange <NUM> are raised above and separated from the rotation-locking protrusions <NUM> of the water inlet <NUM>, which allows the joint <NUM> to rotate freely relative to the housing <NUM> and the water inlet <NUM>. As noted above, the rotatable joint <NUM> avoids entangling of the water inlet hose <NUM> during back-and-forth movement of the pool cleaner <NUM> (<FIG>). The seal <NUM> is captured in the groove <NUM> of the rotatable joint <NUM> and contacts the annular retaining wall <NUM> of the water inlet <NUM>, which ensures a water-tight pathway from the joint <NUM> to the water inlet <NUM>. Also, the thrust bearing <NUM> is captured between the flange <NUM> of the rotatable joint <NUM> and the housing <NUM>, which facilitates smooth rotation of the joint <NUM> in the through-hole <NUM> of the housing <NUM>.

In <FIG>, the joint <NUM> is shown in the locked or non-use configuration, in which the joint <NUM> is removed from the pool and falls downward into the water inlet <NUM> due to gravity. Initially, the flange <NUM> of the joint <NUM> may sit atop the upper end of the rotation-locking protrusion <NUM> of the water inlet <NUM>. The joint <NUM> may be rotated until the rotation-locking slots <NUM> of the flange <NUM> align with and engage the rotation-locking protrusion <NUM> of the water inlet <NUM>, thereby fully seating the joint <NUM> in the locked configuration of <FIG>. The foot <NUM> of the joint <NUM> contacts the base <NUM> of the water inlet <NUM>, and the flange <NUM> of the joint <NUM> contacts the annular retaining wall <NUM> of the water inlet <NUM>. The foot <NUM> and the flange <NUM> have outer diameters larger than the inner diameters of the base <NUM> and the annular retaining wall <NUM>, respectively, thereby limiting downward movement of the joint <NUM> and preventing the joint <NUM> from falling into the water inlet <NUM>. In this locked configuration, the joint <NUM> is restricted from rotating relative to the housing <NUM> and the water inlet <NUM>.

With the lower end <NUM> of the joint <NUM> in the rotationally locked configuration of <FIG>, the water inlet hose <NUM> may be installed onto and/or removed from the upper end <NUM> of the stationary or locked joint <NUM> via rotation. An exemplary installation process is described below with reference to <FIG>, and it is understood that this installation process may be reversed to remove the water inlet hose <NUM> for cleaning, repair, storage, or another purpose. In <FIG>, the coupling <NUM> of the water inlet hose <NUM> (<FIG>) is positioned onto the upper end <NUM> of the joint <NUM>, with the mounting groove <NUM> of the coupling <NUM> aligned with the mounting rib <NUM> of the joint <NUM>. In <FIG>, the coupling <NUM> is moved downward to receive the mounting rib <NUM> of the joint <NUM> through the open bottom end of the mounting groove <NUM> of the coupling <NUM>. In <FIG>, the coupling <NUM> is rotated (e.g., clockwise) to introduce the mounting rib <NUM> of the joint <NUM> into the mounting hole <NUM> of the coupling <NUM>. In <FIG>, the coupling <NUM> is rotated further (e.g., clockwise) to tightly capture the mounting rib <NUM> of the joint <NUM> in the mounting hole <NUM> of the coupling <NUM>. In this position, the locking recess <NUM> of the coupling <NUM> receives the locking protrusion <NUM> of the joint <NUM>, which secures the components firmly together. The coupling <NUM> may contact the stop <NUM> of the joint <NUM> to prevent further rotation of the coupling <NUM>. It is also within the scope of the present disclosure to utilize a threaded or other rotational coupling between the joint <NUM> and the coupling <NUM>.

After installing the water inlet hose <NUM>, the joint <NUM> may resume the rotatable configuration of <FIG> by returning the pool cleaner <NUM> to the pool. The joint <NUM> may float upward, thereby freeing the rotation-locking slots <NUM> of the flange <NUM> from the rotation-locking protrusion <NUM> of the water inlet <NUM> and allowing the joint <NUM> to resume rotation relative to the water inlet <NUM>.

<FIG> provide a second embodiment of a pool cleaner <NUM>' configured to clean a floor and/or sidewalls of a pool. The second pool cleaner <NUM>' is similar to the above-described pool cleaner <NUM> of <FIG>, with like reference numerals identifying like parts, except as described below.

The pool cleaner <NUM>' includes a housing <NUM>' that defines a through-hole <NUM>' in its upper surface. The pool cleaner <NUM>' also includes a hydraulic driving assembly <NUM>' including a water inlet <NUM>' adjacent to the through-hole <NUM>', opposing forward and rearward water outlets 122f', 122r', respectively, and an impeller <NUM>' disposed within the housing <NUM>'. The pool cleaner <NUM>' also includes a filtration assembly <NUM>' disposed within the housing <NUM>' to collect debris. The pool cleaner <NUM>' further includes a transmission assembly <NUM>' operably coupled to the driving assembly <NUM>' and one or more wheels <NUM>' or other traction assemblies (e.g., tracks) operably coupled to the transmission assembly <NUM>'.

The pool cleaner <NUM>' also includes a joint <NUM>' configured to receive a flexible water inlet hose <NUM>'. The joint <NUM>' has a rotatable or use configuration that allows the water inlet hose <NUM>' to rotate relative to the housing <NUM>' during use. The water inlet hose <NUM>' has a locked or non-use configuration that facilitates installation and/or removal of the water inlet hose <NUM>' via rotation of the joint <NUM>' when not in use. In the illustrated embodiment of <FIG>, the joint <NUM>' is externally threaded and the water inlet hose <NUM>' is internally threaded. However, it is also within the scope of the present disclosure to utilize another rotational coupling between the joint <NUM>' and the water inlet hose <NUM>', such as the rotational coupling described above with respect to <FIG>.

The water inlet <NUM>' of the driving assembly <NUM>' is shown in <FIG> and <FIG> and includes a cylindrical side wall <NUM>'. An external thread <NUM>' extends radially outward from the side wall <NUM>'. A lower flange or base <NUM>', an intermediate flange <NUM>', and an upper flange <NUM>' each extend radially inward from the side wall <NUM>'. The intermediate flange <NUM>' and the upper flange <NUM>' cooperate to define an internal groove <NUM>' that is configured to receive a seal <NUM>' (e.g., an O-ring).

The water inlet <NUM>' is coupled to a lock nut <NUM>'. The lock nut <NUM>' includes an internal thread <NUM>' that engages the external thread <NUM>' of the water inlet <NUM>'. The lock nut <NUM>' also includes an outer edge <NUM>' positioned above the through-hole <NUM>' of the housing <NUM>' and having an outer diameter larger than the inner diameter of the through-hole <NUM>' to prevent the lock nut <NUM>' (and the water inlet <NUM>' coupled to the lock nut <NUM>') from dropping through the through-hole <NUM>'. In this way, the lock nut <NUM>' supports the water inlet <NUM>' in the housing <NUM>'.

The joint <NUM>' is shown in <FIG> and <FIG> and includes a generally cylindrical side wall <NUM>' that extends between a lower end <NUM>' and an upper end <NUM>'. The illustrative joint <NUM>' tapers in width toward the lower end <NUM>', but this shape may vary. The joint <NUM>' includes an external slot <NUM>' that extends axially along the side wall <NUM>' from an open end toward the upper end <NUM>' to a locking recess <NUM>' toward the lower end <NUM>'. Near the lower end <NUM>', the joint <NUM>' includes a flange <NUM>' that extends radially outward from the side wall <NUM>'. At the upper end <NUM>', the joint <NUM>' is externally threaded to mate with the internally threaded water inlet hose <NUM>', as described above.

The joint <NUM>' is rotatably coupled to a rotary sleeve <NUM>'. The rotary sleeve <NUM>' includes an elastic arm <NUM>' with a locking tip <NUM>' that is biased radially inward to engage the joint <NUM>' (See also <FIG> and <FIG>). The rotary sleeve <NUM>' may be coupled to the joint <NUM>' by sliding the elastic arm <NUM>' downward through the external slot <NUM>' until the locking tip <NUM>' snaps radially inward into the locking recess <NUM>'. The rotary sleeve <NUM>' is positioned above the through-hole <NUM>', and the outer diameter of the rotary sleeve <NUM>' exceeds the inner diameter of the through-hole <NUM>' to prevent the rotary sleeve <NUM>' (and the joint <NUM>' coupled to the rotary sleeve <NUM>') from dropping through the through-hole <NUM>' and into the water inlet <NUM>'. The rotary sleeve <NUM>' is also positioned above the lock nut <NUM>' and is accessible by the user.

The joint <NUM>' is shown in the rotatable or use configuration in <FIG>, in which the joint <NUM>' is positioned in the pool and floats upward in the water. The flange <NUM>' of the joint <NUM>' is captured beneath the intermediate flange <NUM>' of the water inlet <NUM>', thereby limiting upward movement of the joint <NUM>'. The seal <NUM>' is captured in the groove <NUM>' of the water inlet <NUM>' and contacts the rotatable joint <NUM>', which ensures a water-tight pathway from the joint <NUM>' to the water inlet <NUM>'. In this rotatable configuration, the joint <NUM>' is free to rotate relative to the housing <NUM>' and the water inlet <NUM>'. As noted above, the rotatable joint <NUM>' avoids entangling of the water inlet hose <NUM>' during back-and-forth movement of the pool cleaner <NUM>' (<FIG>).

In the locked or non-use configuration (not shown), the joint <NUM>' is removed from the pool and falls downward into the water inlet <NUM>' due to gravity. The flange <NUM>' of the joint <NUM>' contacts the base <NUM>' of the water inlet <NUM>'. The flange <NUM>' has an outer diameter larger than the inner diameter of the base <NUM>', thereby limiting downward movement of the joint <NUM>' and preventing the joint <NUM>' from falling into the water inlet <NUM>'. The user may grip the water inlet hose <NUM>' with one hand to restrict the water inlet hose <NUM>' from rotating relative to the housing <NUM>', thereby fixing the position of the water inlet hose <NUM>' relative to the housing <NUM>'. Then, the user may rotate the exposed rotary sleeve <NUM>' relative to the stationary water inlet hose <NUM>' with the other hand. Because the locking tip <NUM>' of the rotary sleeve <NUM>' is engaged with the locking recess <NUM>' of the joint <NUM>', this rotation of the rotary sleeve <NUM>' also rotates the joint <NUM>' relative to the stationary water inlet hose <NUM>'. Such rotation of the rotary sleeve <NUM>' may be performed to attach and/or detach the joint <NUM>' and the water inlet hose <NUM>'.
