Docking Unit Sequential Dirt Emptying for Surface Cleaning Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses face challenges in efficiently emptying dirt collection regions, particularly when coarser and finer dirt are mixed, as existing designs often require complex mechanisms and do not effectively utilize the suction motor for emptying, leading to incomplete dirt removal and potential filtration issues.
Innovation Solution
A surface cleaning apparatus with a docking unit that allows for sequential emptying of dirt collection regions, utilizing a movable valve and UV light disinfection, where the suction motor is used to facilitate dirt transfer and the UV light treats the air treatment assembly during emptying, improving filtration efficiency and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex opening mechanism is used to empty the dirt collection region, then the dirt can be emptied, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The air treatment assembly is divided into separate functional regions: a cyclone separation chamber for dirt removal and a filter housing for filtration. This segmentation allows the dirt collection region to be accessed and emptied independently through a simple access opening, without requiring complex mechanisms to disassemble the entire assembly.
Solution Approach 2:
The dirt collection region is extracted as a separately accessible component within the air treatment assembly. A simple opening mechanism allows direct access to the cyclone separator and dirt collection chamber, enabling easy emptying without disassembling the filter housing or other critical components.
2Manufacturing precision
If coarser and finer dirt are emptied together, then the emptying process is simple, but filtration efficiency decreases due to mixed dirt types
Solution Approach 1:
The air treatment assembly segments dirt collection by function: the cyclone separator handles coarser particle separation while the filter handles finer particles. The design allows selective access to the cyclone separator for emptying coarser dirt, while the filter remains protected and can be emptied separately through its own access opening, maintaining filtration efficiency.
Solution Approach 2:
The cyclone separator performs preliminary separation of coarser particles from the air stream before air enters the filter. This preliminary action allows coarser dirt to be emptied from the cyclone separator first, preventing it from contaminating the filter and maintaining filtration efficiency for finer particles.
3Productivity
If the suction motor is not used for emptying, then the motor is protected from overload, but the emptying process becomes less efficient
Solution Approach 1:
The cyclone separator performs preliminary separation of dirt particles from the air stream before the air enters the suction motor. During emptying operations, this separation system can be activated to remove bulk dirt quickly, allowing the motor to operate within safe parameters while maintaining efficient dirt removal capability.
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 efficient emptying of both coarser and finer dirt, enhancing filtration by allowing sequential emptying and utilizing the suction motor for motive force, while also disinfecting the air treatment assembly, thus improving the overall cleaning process and hygiene.
Implementation Method 1
a suction motor positioned in the air flow path wherein, during a surface cleaning apparatus emptying operation, the suction motor generates a flow of air that transfers dirt from the air treatment assembly into the docking unit
Implementation Method 2
a UV light emitting member that is located interior of the surface cleaning apparatus and is operable to disinfect a portion of an exterior surface of the surface cleaning apparatus wherein the UV light emitting member is activated while the surface cleaning apparatus is docked at a docking station
