Methods and systems for an autonomously retracting hose
View Patent ↗A swimming pool cleaner coupled to a hose, wherein the hose is configured to automatically extend and retract.
1 . A self-contained hose reel for a pool comprising:
a housing;
a valve positioned within the housing, the valve configured to change between a first mode and a second mode based on fluid flowing through the valve;
a drum configured to move a hose, wherein the drum rotates in a first direction when the valve is in the first mode, and the drum rotates in a second direction when the valve is in the second mode, the housing, the valve, and the drum are configured to be positioned within the pool, the valve being positioned centrally within the drum and the fluid flows through the valve within the drum in an axis perpendicular to the rotation of the rotation of the drum.
2 . The self-contained hose reel of claim 1 , wherein the valve is configured to be static while a pool vacuum moves, wherein the valve is configured to allow flow to a pool vacuum.
3 . The self-contained hose reel of claim 1 , wherein the hose rotates in the first direction when the valve is in the first mode, and in the second direction when the valve is in the second mode.
4 . The self-contained hose reel of claim 3 , further comprising:
an annular space positioned between the drum and an inner surface of the housing, wherein the hose is wound and unwound in the annular space, the hose being positioned within the annular space when the fluid flows through the valve and the hose to transition the valve between the first mode and the second mode.
5 . The self-contained hose reel of claim 3 , further comprising:
a transfer gear configured to rotate based on the drum rotating.
6 . The self-contained hose reel of claim 5 , further comprising:
a first roller and a second roller, wherein the transfer gear is configured to maintain the hose under tension, the first roller and the second roller being positioned outside of an annular space.
7 . The self-contained hose reel of claim 1 , wherein the valve is configured to switch from the second mode to the first mode based on stopping the flowing fluid through an inlet port.
8 . The self-contained hose reel of claim 1 , wherein the valve changes between the first mode and the second mode based on hydraulic pressure rotating the valve.
9 . The self-contained hose reel of claim 1 , wherein the valve is controlled by an external water supply, the housing include a first face and a second face, wherein the first face of the housing is positioned directly adjacent to a vertical sidewall of the pool.
10 . The self-contained hose reel further of claim 1 , further comprising:
a bidirectional turbine, and a gearbox configured to autonomously wind and unwind the hose, wherein the valve is a three mode valve.
