Cyclonic Dirt Chamber Door Layout for Easier Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclonic surface cleaning apparatuses with removable dirt chambers face issues where the separation plate impedes emptying when the door is open, and dirt accumulation between the door and plate makes it difficult to empty the dirt collection chamber, especially when the door has an annular lip.
Innovation Solution
A surface cleaning apparatus with a dirt chamber featuring a removably mounted door that allows for easy emptying by removing the separation plate, which is not obstructing the cyclone or dirt collection chamber, and can be washed to remove accumulated dirt, with the door being pivotally mounted to prevent obstruction during emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door has an annular lip to seal the chamber, then sealing effectiveness is improved, but dirt accumulates in the space between the door and separation plate making it difficult to empty
Solution Approach 1:
The separation plate is extracted from the door assembly, eliminating the problematic space between the door and plate where dirt would accumulate. The door with its annular lip maintains sealing effectiveness, while the removed plate eliminates the emptying obstruction.
Solution Approach 2:
The door assembly is segmented by separating the door from the separation plate. The door retains its sealing function with the annular lip, while the separation plate is repositioned to a fixed location, allowing complete access to the dirt collection chamber for easy emptying.
2Stability of the object's composition
If the separation plate is fixed to the door, then structural stability is improved, but the plate blocks access to the cyclone chamber when the door is open
Solution Approach 1:
The separation plate is extracted from the moving door assembly and repositioned to a fixed location on the cyclone separator housing. This maintains the structural integrity of the door while eliminating the blocking effect during door operation.
Solution Approach 2:
The door assembly is made dynamic by allowing it to pivot open for access, while the separation plate is made static by fixing it to the housing. This dynamic configuration allows the door to move freely without the plate interfering with access to the cyclone chamber.
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 solution enables effortless emptying of the dirt collection chamber without obstruction, allowing for effective cleaning and maintenance by removing the separation plate and door, facilitating the removal of dirt and preventing re-accumulation.
Implementation Method 1
a cyclone separator for separating dirt and dust from an airflow
Implementation Method 2
The cyclonic separator is arranged in a generally upright orientation (i.e., the air rotates about a generally vertical axis in use)
