Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet type dust collecting apparatuses with multiple dust bins face issues of water level instability due to pressure differences between bins, leading to reduced dust separating efficiency and potential water overflow into the vacuum cleaner, causing damage to components.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple dust bins are connected to allow simultaneous water filling, then user convenience is improved, but water level stability deteriorates due to pressure differences between bins
Solution Approach 1:
The dust bin system is segmented into multiple independent dust collecting areas (first dust collecting area and second dust collecting area), each with its own water inflow hole and sealing member. This segmentation allows independent water level control in each area while maintaining the ability to fill multiple bins simultaneously through the water distribution passage part.
Solution Approach 2:
The sealing member acts as an intermediary element that selectively opens or closes water inflow holes in each dust collecting area. This intermediary mechanism enables independent control of water filling in each bin, preventing uncontrolled water movement between areas while still allowing simultaneous filling when both sealing members are open.
2Quantity of substance
If water can move freely between dust collecting areas, then uniform water distribution is achieved, but dust separating efficiency deteriorates due to pressure differences
Solution Approach 1:
Each dust collecting area is given local quality through individual sealing members that can independently control water inflow. This allows each area to maintain its own water level and pressure conditions optimized for dust separation, while still being part of the overall multi-bin system.
3Ease of operation
If water level is not properly maintained in dust collecting areas, then filling convenience is improved, but harmful effects occur such as water overflow damaging vacuum cleaner components
Solution Approach 1:
The sealing members are designed to be opened or closed preliminarily before water filling operations. By closing the sealing member in a dust collecting area before filling another area, the system preliminarily prevents potential water overflow and migration, protecting filters and electronic components from damage.
Solution Approach 2:
The sealing members provide beforehand cushioning by creating a barrier that prevents uncontrolled water movement between dust collecting areas. This protective barrier is in place before water filling operations, cushioning against potential harmful effects of water overflow or migration to sensitive components.

AI summary
A wet type dust collecting apparatus of a vacuum cleaner is disclosed. The wet type dust collecting apparatus includes a dust bin having at least two dust collecting areas, each of which at least one water inflow holes is formed, and a water distribution passage part to connect the water inflow holes in communication with each other; and a dust bin cover coupled to the dust bin and having a sealing member to open and close up at least one of the water inflow holes. Accordingly, a user can simultaneously fill the entire of the plurality of dust collecting areas with water by filling any one of the dust collecting areas with water. Further, in operation of the vacuum cleaner, the sealing member closes up at least one of the water inflow holes to prevent the water from being moved between the dust collecting areas. According to this, a dust separating efficiency is prevented from being deteriorated due to the movement of water in operation of the vacuum cleaner, and an exhaust runs a lot smoother. Also, since the water filled in the dust bin strongly collects separated dust while whirling, the dust separating efficiency is enhanced.
