Variable-Rotation Pool Cleaning Nozzle Head for Energy Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pool cleaning nozzles require extensive pump operation time and energy to clean complex pool areas like steps and alcoves, leading to inefficient use of resources and potential erosion of pool surfaces due to uneven water pressure distribution.
Innovation Solution
The use of a variable rotating nozzle head with multiple openings directed at different angles, which intermittently raises and rotates to target specific areas of the pool, incrementally spraying water and adjusting its position to cover the entire surface efficiently, reducing the number of pump cycles and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional full rotation cleaning nozzles are used to clean steps and slopes, then cleaning coverage is achieved, but pump operation time and energy consumption increase significantly
Solution Approach 1:
The cleaning head is divided into multiple independent nozzle openings (first, second, third, and fourth nozzles) positioned at different orientations. Each nozzle cleans a specific sector of the pool surface, allowing the head to rotate through smaller angles (45-180 degrees) rather than full 360-degree rotations, thereby reducing pump operation time while maintaining comprehensive cleaning coverage.
Solution Approach 2:
The cleaning head is designed to rotate dynamically between 45 to 180 degrees in alternating directions (first and second rotational directions) rather than fixed full rotation. This dynamic, variable-angle rotation optimizes the cleaning path to cover steps, slopes, and other complex areas more efficiently, reducing the total number of rotation cycles required.
2Productivity
If conventional full rotation cleaning nozzles are used, then cleaning coverage is achieved, but energy consumption increases
Solution Approach 1:
Multiple nozzle openings are positioned at different orientations to divide the cleaning task into separate sectors. This segmentation allows the cleaning head to operate at lower rotation angles (45-180 degrees) per cycle, reducing the mechanical work and energy consumption while maintaining complete coverage of the pool surface through coordinated action of all nozzles.
Solution Approach 2:
The variable rotation angle (45-180 degrees) and alternating directional rotation create a dynamic cleaning pattern that optimizes energy efficiency. By rotating less than full 360 degrees and changing direction, the system reduces the total mechanical work required compared to conventional continuous full rotation, thereby lowering energy consumption while preserving cleaning effectiveness.
3Productivity
If conventional cleaning nozzles are used to clean complex areas, then cleaning is achieved, but pump sizing must be larger
Solution Approach 1:
The cleaning head distributes cleaning responsibility across multiple nozzle openings positioned at different orientations. This segmentation allows each nozzle to handle a specific zone, reducing the water flow requirement per nozzle and thereby allowing the use of a smaller pump while maintaining the ability to clean complex areas like steps and slopes effectively.
Solution Approach 2:
The variable-angle rotation (45-180 degrees) and alternating directional movement create an optimized cleaning trajectory that improves water distribution efficiency. This dynamic pattern ensures that water is delivered more effectively to hard-to-reach areas, reducing the total pump power needed compared to conventional full rotation systems that require larger pumps to compensate for less efficient coverage.

Function Achieved in This Case
This approach significantly reduces pump operation time, minimizes erosion by optimizing water distribution, and effectively cleans hard-to-reach areas with fewer nozzle rotations, thereby saving energy and extending equipment lifespan.
Implementation Method 1
Conventional cleaning nozzles for swimming pools utilize water pressure generated by a pool pump to direct a stream of water across a surface of the pool to entrain and move contaminants from the surface toward a drain
Implementation Method 2
direct a stream of water across a surface of the pool to entrain and move contaminants from the surface toward a drain
Implementation Method 3
incrementally rotating the nozzle head in a first rotational direction, retracting the nozzle head flush with an inner surface of the swimming pool, and incrementally rotating the nozzle head in a second rotational direction, opposite the first rotational direction

AI summary
Swimming pool in-floor cleaning heads may be used to variably clean a swimming pool floor by raising a nozzle head positioned on a step of the swimming pool under water and having at least first and second nozzle openings directed in different directions toward surfaces of the step, and simultaneously ejecting first and second streams of water from the first and second nozzle openings toward, respective, first and second portions of the step, variably rotating the nozzle head in a first rotational direction, retracting the nozzle head flush with an inner surface of the swimming pool, and in some cases incrementally rotating the nozzle head in a second direction, opposite the first direction.
