Methods and systems for an autonomously retracting hose

Abstract

A swimming pool cleaner coupled to a hose, wherein the hose is configured to automatically extend and retract

What is claimed is: 
     
         1 . An autonomously retracting hose comprising:
 a housing with an inlet and a plurality of outlet ports, the plurality of outlet ports extending orthogonal to a central axis of the housing and the inlet of the housing, the plurality of outlet ports including a first outlet and a second outlet,;   a valve with a plurality of valve ports, the valve being configured to move longitudinally and rotate within the housing to change from a first mode to a second mode, the valve ports being configured to engage with the first outlet in the first mode or the second outlet in the second mode, the valve including an open inner face and a closed outer face;   a first winding arm coupled to the first outlet, the first winding arm being configured to emit fluid in a first direction when the valve is in the first mode, and the first winding arm does not receive fluid from the housing when the valve is in the second mode;   an unwinding arm coupled to the second outlet, the unwinding arm being configured to emit fluid in the second direction when the valve is in the second mode, and the unwinding arm does not receive fluid from the housing when the valve is in the first mode, wherein the first direction and the second direction are opposite directions;   a drum being including a first face and a second face, the first face being configured to be positioned adjacent to a sidewall of a pool, wherein the first face and the second face are configured rotate based on fluid flowing out of the plurality of outlet ports, wherein the housing and the valve are positioned between the first face and the second face, and an annular space is formed outside of the housing within the drum, the drum rotating in a first direction in the first mode and the drum rotating in a second direction in the second mode.   
     
     
         2 . The autonomously retracting hose of  claim 1 , wherein a central axis of the housing is orthogonal to openings of the plurality of ports. 
     
     
         3 . The autonomously retracting hose of  claim 1 , wherein the valve is configured to move from the first mode to the second mode and from the second mode to the first mode based on hydraulic forces being applied the closed face, wherein the valve moves between from the first mode and the second mode based on the hydraulic forces being applied to the closed face in a first direction being greater than a flow threshold a first time, then being less than the flow threshold, and subsequently greater than the flow threshold a second time. 
     
     
         4 . The autonomously retracting hose of  claim 3 , further comprising:
 a pool pump with a supply line, the supply line being communicatively coupled to the valve, wherein the pool pump is configured to emit fluid towards the valve to move the valve from the first mode to the second mode and to move the valve from the second mode to the first mode.   
     
     
         5 . The autonomously retracting hose of  claim 4 , further comprising:
 a coil spring configured to supply a constant force against the close face of the valve; and   pegs positioned on an outer circumference of the valve configured to interface with center pivot grooves within the housing to assist in the rotation of the valve from the first mode to the second mode and to rotation of the valve from the second mode to the first mode.   
     
     
         6 . The autonomously retracting hose of  claim 4 , wherein the constant force is weaker than the hydraulic forces being applied to the closed face when the pool pump is supplying fluid, and the constant force is stronger than the hydraulic forces being applied to the closed face when the pool pump is turned off. 
     
     
         7 . The autonomously retracting hose of  claim 1 , wherein the outlet ports having four ports, and the valve ports having two ports. 
     
     
         8 . The autonomously retracting hose of  claim 7 , further comprising:
 a first jet coupled to the a first winding arm;   a second jet coupled to the unwinding arm, wherein a first cross sectional area of the first jet is larger than a second cross sectional area of the second jet.   
     
     
         9 . The autonomously retracting hose of  claim 8 , wherein the first jet faces the second jet.
