Horizontal Cyclone Layout for Larger Vacuum Dust Bin Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclone dust-separating apparatuses in vacuum cleaners have a small dust bin capacity due to their vertical design, requiring frequent emptying and allowing dust to flow back into the cyclone unit due to swirling air.
Innovation Solution
A cyclone dust-separating apparatus with a horizontally arranged cyclone unit and a vertically oriented dust bin, featuring an air outflow passage that reduces piping loss and prevents dust from flowing back, allowing for a larger dust bin capacity and improved separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the cyclone unit is vertically arranged, then the dust bin can be connected to the bottom end, but the dust bin capacity becomes small requiring frequent emptying
Solution Approach 1:
The cyclone unit is reoriented from a vertical arrangement to a horizontal arrangement. This dimensional change allows the dust bin to be positioned at the bottom end of the horizontally arranged cyclone unit, enabling the dust bin to extend vertically downward rather than being constrained by the vertical cyclone arrangement. This dimensional reconfiguration significantly increases the dust bin capacity while maintaining a compact overall height of the apparatus.
2Productivity
If air is lowered to the internal space of the dust bin, then dust separation occurs, but dust stored in the dust bin is entrained by swirling air and flows backward to the cyclone unit
Solution Approach 1:
The harmful swirling air flow that causes dust to be entrained and flow backward is extracted or removed from the dust bin internal space. The air outflow passage is configured to discharge air from the cyclone chamber in a direction that bypasses the dust storage area, preventing the swirling air from contacting and re-entraining the separated dust. This extraction of the harmful air flow path resolves the contradiction between maintaining dust separation efficiency and preventing dust from flowing backward.
3Volume of stationary object
If the cyclone unit is vertically arranged, then the apparatus structure is compact, but the dust bin capacity is reduced and dust can flow back
Solution Approach 1:
The cyclone unit is reoriented from a vertical arrangement to a horizontal arrangement. This dimensional change allows the dust bin to be positioned at the bottom end of the horizontally arranged cyclone unit, enabling the dust bin to extend vertically downward rather than being constrained by the vertical cyclone arrangement. This dimensional reconfiguration significantly increases the dust bin capacity while maintaining a compact overall height of the apparatus.
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 increases the dust bin volume, reducing the frequency of emptying and preventing dust from flowing back to the cyclone unit, while enhancing dust separation efficiency and convenience.
Implementation Method 1
a cyclone dust-separating apparatus which whirls air laden with dirt or dust and separates the dirt or dust therefrom
Implementation Method 2
External air drawn into the cyclone unit through a side of the cyclone unit is lowered while whirling within an internal space of the dust bin as well as within an internal space of the cyclone unit

AI summary
A cyclone dust-separating apparatus is disclosed. The dust-separating apparatus includes a cyclone unit having an air inlet and an air outlet so as to remove dust or dirt from air, and a dust bin joined to a bottom end of the cyclone unit so as to store the dust or dirt separated by the cyclone unit. The cyclone unit is installed in such a manner that a longitudinal axis thereof is substantially horizontally arranged. The dust bin is installed in such a manner that a longitudinal axis thereof is substantially perpendicular to the longitudinal axis of the cyclone unit. The dust bin has an air outflow passage connected with the air outlet, so that air discharged from the cyclone unit passes through the dust bin and then discharges in a bottom end direction of the dust bin.
