Pool Pump Automatic Air Venting With Float-Sealed Exhaust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool pumps face issues with air entrapment, which disrupts liquid flow and can damage the impeller or pump, requiring manual operation of a relief valve that is prone to failure over time, and are susceptible to debris entry.
Innovation Solution
A pool pump design featuring a buoy room cover with a buoy and buoy room valve that automatically releases air without manual operation, using seals and a plug mechanism to isolate the chamber from the atmosphere, ensuring air is released efficiently and preventing debris entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual relief valve with a screw is used to release air, then air can be vented from the pump, but the screw may become stuck, cross-threaded, or degrade over time requiring replacement of the entire unit
Solution Approach 1:
The patent removes the screw and threaded connection components from the relief valve assembly. The relief valve is instead held in place by a snap-fit mechanism where the valve body engages with ribs on the pump housing, eliminating the screw entirely. This extraction of the screw component directly resolves the reliability issues associated with screws becoming stuck, cross-threaded, or degraded over time.
Solution Approach 2:
The relief valve assembly includes an automatic float-operated mechanism that opens and closes the valve based on water level in the pump housing. The float rises with water level and automatically lifts the valve plug to release air pockets, then automatically closes when water level drops. This self-service automation eliminates the need for manual operation and associated mechanical components.
2Ease of operation
If a manual relief valve is used, then air can be released, but manual operation is required which is inconvenient and time-consuming
Solution Approach 1:
The relief valve incorporates a float mechanism that automatically detects air pockets through water level changes and triggers valve opening without user intervention. The float rises when air displaces water, automatically lifting the valve plug to vent air, then automatically closes when water returns. This self-service operation eliminates manual intervention entirely, making operation as easy as installing the device and resolving the time loss associated with repeated manual operations.
Solution Approach 2:
The float mechanism provides continuous feedback about the water level and air pocket presence in the pump housing. When air accumulates and displaces water, the float rises, providing feedback that triggers the valve opening action. This feedback loop enables automatic response to air pocket conditions without requiring user monitoring or manual operation.
3Reliability
If the pump housing is open for air release, then air can be vented, but debris may enter the pump
Solution Approach 1:
The relief valve assembly is segmented into separate functional components: a valve body with sealed opening, a movable plug for air passage, and a float actuation mechanism. The valve body includes a dedicated air release passage that is sealed from the pump housing except when the plug is actively lifted by the float. This segmentation allows air to be vented through a controlled path while the sealed construction prevents debris from entering the pump during the air release process.
Solution Approach 2:
The relief valve plug acts as a flexible seal that can be lifted slightly to allow air passage while maintaining a tight seal against the valve body. The plug is designed to flex or lift only enough to vent air bubbles, then automatically returns to seal the opening. This flexible sealing mechanism allows efficient air release while preventing debris entry, as the sealed opening remains closed except during active air venting when the float directly lifts the plug.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides a reliable and automatic air release mechanism that enhances pump longevity by reducing component failure and debris ingress, maintaining efficient liquid flow without user intervention.
Implementation Method 1
a buoy within the chamber configured to fall when the liquid portion within the chamber is below a first level
Implementation Method 2
the pump converts electrical energy into mechanical energy as a rotating impeller pushes a liquid
Implementation Method 3
The rotating impeller creates a pressure of the liquid as it moves from the one or more inlets located inside the pool through the pump
