Dual Dust Separation Layout for Compact Cyclone Cleaners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face issues with dust separation performance and efficiency, particularly when the suction inlet and motor are not in a direct connection, leading to deteriorated cleaning efficiency and difficulty in effectively separating dust.
Innovation Solution
A cleaner design featuring a primary dust separation structure and a secondary cyclone separation system arranged separately, with plate-shaped members at angles to direct air flow, allowing for effective dust collection without a direct connection between the suction inlet and motor, enhancing dust separation performance and utility of internal space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cyclone is used for dust separation, then the structure is simple, but dust separation performance deteriorates and filters require frequent replacement
Solution Approach 1:
The dust separation system is divided into multiple cyclones instead of using a single cyclone. This segmentation allows for improved dust separation performance while maintaining structural simplicity, as each cyclone operates independently to separate dust particles from air flow.
Solution Approach 2:
Multiple cyclones are arranged in a nested or compact configuration within the cleaner body, allowing efficient use of internal space. The cyclones are positioned to optimize air flow paths while maintaining a compact overall structure.
2Productivity
If a direct connection structure from suction inlet to motor is used, then air flow path is short, but it is difficult to perform effective cleaning when filter is blocked
Solution Approach 1:
The air flow path is designed with flexible routing that can adapt to different operating conditions. When the filter becomes blocked, the system can maintain effective cleaning by allowing air to be drawn from alternative paths, including the dust collection chamber, ensuring continuous operational reliability.
Solution Approach 2:
The dust collection chamber serves as an intermediary space that can provide alternative air flow paths. When the primary filter is blocked, air can be drawn through the dust collection chamber to reach the motor, maintaining air flow efficiency and cleaning effectiveness.
3Volume of stationary object
If primary and secondary dust separation structures are arranged concentrically, then space utilization is high, but the height of the cleaner increases causing user inconvenience
Solution Approach 1:
The dust separation structures are arranged in a horizontal plane rather than vertically stacked concentrically. This dimensional change allows both primary and secondary separation structures to coexist without significantly increasing the height of the cleaner, while still maintaining efficient space utilization within the available volume.

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 achieves excellent dust separation performance, simplifies manufacturing, and prevents cleaning efficiency deterioration by allowing dust to join the air flow, enhancing the utility of the cleaner's internal space and enabling various shapes.
Implementation Method 1
a cyclone portion rotating the air, which has passed through the dust separator, to separate the dust from the air
Implementation Method 2
a dust separator that separates dust from air while air entering from the suction inlet moves
Data Source
AI summary
A cleaner is disclosed, which comprises a main body including an suction inlet through which air containing dust enters, a dust separator provided to separate dust from the air while the air entering from the suction inlet is moving, a first dust collector configured to collect the dust separated by the dust separator, a cyclone portion configured to rotate the air to separate the dust from the air, and a second dust collector collecting the dust separated by the cyclone portion. The dust separator is provided with a plurality of plate shaped members arranged at a predetermined angle with respect to a moving direction of the air, and arranged to be spaced apart from one another to move the air.
