Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wet type dust collecting apparatuses face challenges in enhancing dust separating efficiency and extending the dust collecting region while minimizing water overflow and overturning, especially due to the limitations of single cyclone units and dry type dust collection methods.
Innovation Solution
A wet type dust collecting apparatus for a vacuum cleaner featuring a first separating unit with a centrifugal separating pipe and multiple second centrifugal separating units, where air is directly contacted with water to filter out dust, and a water overflow prevention mechanism is implemented to prevent water overflow even when the apparatus is tilted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cyclone unit is used for dust separation, then the device complexity is reduced, but the dust separating efficiency decreases
Solution Approach 1:
The dust collecting apparatus is divided into multiple functional units: a first cyclone unit for initial dust separation and a second cyclone unit for fine dust separation. This segmentation allows each unit to specialize in different separation tasks, improving overall dust separating efficiency while maintaining manageable structural complexity through modular design.
2Productivity
If the minor diameter of centrifugal separating pipe decreases to increase water rotating speed, then dust separating efficiency increases, but the dust collecting region becomes limited
Solution Approach 1:
The system uses two separate cyclone units with different pipe diameters and functions. The first cyclone unit has a larger diameter for handling high-volume air flow and general dust separation, while the second cyclone unit has a smaller diameter optimized for high-speed rotation and fine dust separation. This segmentation allows the system to maintain both broad dust collecting region and high dust separating efficiency simultaneously.
3Productivity
If water is filled in the dust container for wet type dust collection, then dust separating efficiency is enhanced, but water overflow and overturning occur when the apparatus is tilted
Solution Approach 1:
A water overflow prevention groove is designed into the dust container structure before tilting occurs. This groove creates a physical barrier that prevents water from overflowing even when the apparatus is tilted during operation, thereby maintaining reliability without compromising the dust separating efficiency provided by wet collection.
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 apparatus enhances dust separation and collection efficiency by increasing the area and time of air contact with water, improving fine dust separation, and minimizing water overflow through the use of multiple centrifugal separating units and a water overflow prevention system.
Implementation Method 1
a first centrifugal separating pipe which forms a first centrifugal separating region which filters out dust by rotating air which is inlet via the first air inlet
Implementation Method 2
a plurality of second centrifugal separating units which filter out dust from the air which is discharged from the first separating unit
Implementation Method 3
the plurality of the second centrifugal separating units eliminate dust from the inlet air via water which is filled inside of the second centrifugal separating units. The air which is inlet to the second centrifugal separating units is directly contacted to the water which is filled inside of the second centrifugal separating units and rotated so that dust in air is filtered out
Implementation Method 4
a water overflow prevention unit which prevents water which is inlet into the first dust container and the second dust containers from being overflown even when a vacuum cleaner is overturned
