Solution Overview
Problem
Existing cleaners face issues with the compression mechanism not accurately returning to the compression standby position due to assembly errors and interference with air flow, leading to reduced dust separation performance.
Innovation Solution
The cleaner incorporates a frame with guide parts that allow for precise positioning and rotation of the compression mechanism, using transfer parts connected eccentrically to the operating part, ensuring accurate return to the standby position and guiding air and dust flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dust compression part moves in contact with the inner circumferential surface of the dust bin, then the inner circumferential surface can be cleaned, but dust may accumulate between the dust compression part and the inner circumferential surface, preventing smooth vertical movement and accurate positioning at the compression standby position
Solution Approach 1:
The dust compression part is divided into a compression body and a separate cleaning member. The cleaning member can rotate relative to the compression body, allowing it to clean the inner circumferential surface without interfering with the vertical movement and positioning of the compression body. This segmentation resolves the conflict between cleaning function and positioning accuracy.
Solution Approach 2:
The cleaning member is designed to rotate dynamically during the movement of the compression part. This rotation enables the cleaning member to maintain contact with the inner circumferential surface for cleaning purposes while allowing the compression body to move vertically smoothly and position accurately at the standby position without dust accumulation interference.
2Productivity
If the compression mechanism is positioned at the compression standby position, then air and dust can flow through the opening without resistance, but if it does not accurately return to this position, it acts as a flow resistance and degrades dust separation performance
Solution Approach 1:
A spring mechanism provides feedback force that automatically returns the compression part to the compression standby position after compression operation. This elastic feedback ensures the compression part accurately returns to the position where it does not obstruct air and dust flow, maintaining dust separation performance without requiring complex positioning control systems.
3Ease of operation
If the transfer parts are disposed eccentrically to transfer the operation force, then the compression mechanism can be operated, but assembly errors may prevent accurate return to the compression standby position
Solution Approach 1:
The transfer parts are intentionally disposed eccentrically relative to the compression part to enable effective operation force transfer. The asymmetric arrangement allows the spring mechanism to effectively return the compression part to the standby position despite the eccentric transfer, as the spring provides a restoring force that compensates for the asymmetric force transfer path.

AI summary
A cleaner of the present invention comprises: a housing including a suction opening, a cyclone part which separates dust from air suctioned through the suction opening, and a dust bin which stores the dust separated from the air by the cyclone part; a guide fixed in position within the housing; a frame which is movable to a compression standby position and a dust compression position for compressing the dust within the dust bin, in the housing, and comes into contact with the guide at the compression standby position; a first guide part provided on the frame; and a second guide part provided on the guide and coupled to the first guide part at the compression standby position of the frame, wherein any one of the first guide part and the second guide part is a protrusion and the other is a groove in which the protrusion is accommodated.
