Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi cyclone dirt separating apparatuses in vacuum cleaners face challenges in compact design due to increased height and complex inner structures, leading to higher pressure loss and weight issues with the motor mounting space.
Innovation Solution
A cyclone dirt separating apparatus with a discharge guide duct that passes through the cyclone body and dirt collecting case in a vertical direction, allowing air from the second cyclone chamber to directly enter the motor mounting space, reducing the overall height and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi cyclone dirt separating apparatus is used to enhance dirt collection efficiency, then dirt separation performance is improved, but the overall height and device complexity increase
Solution Approach 1:
The patent implements nesting by placing the first cyclone chamber inside the second cyclone chamber, with the first cyclone chamber positioned at the center and the second cyclone chamber surrounding it. This nested configuration allows multiple cyclone separation stages to be accomplished within a compact vertical footprint, thereby improving dirt collection efficiency without significantly increasing the overall height of the apparatus.
Solution Approach 2:
The patent transitions from a horizontal arrangement of cyclone chambers to a vertical nested arrangement. By utilizing the vertical dimension and nesting chambers one within another, the design achieves multi-stage dirt separation while maintaining a compact overall height, effectively resolving the contradiction between separation performance and height.
2Ease of operation
If conventional air discharge passages are used, then air can be discharged from the cyclone chamber, but the passage length increases causing higher pressure loss
Solution Approach 1:
The patent extracts the air discharge function from the conventional upper discharge location and repositions it to the lower portion of the cyclone chamber. The discharge passage is configured to extend downward from the lower side of the cyclone chamber, allowing air to be discharged at a lower position. This extraction and repositioning of the discharge function shortens the air passage length and reduces the number of bends, thereby minimizing pressure loss while maintaining effective air discharge.
3Ease of manufacture
If the motor mounting space is located at the lower side, then motor installation is facilitated, but the air discharge passage becomes longer and more complex
Solution Approach 1:
The patent merges the air discharge passage with the motor mounting space by positioning the discharge passage to directly connect to the lower side of the cyclone chamber where the motor is mounted. This integration eliminates the need for separate, lengthy air discharge passages and reduces structural complexity, while still facilitating motor installation at the lower side of the apparatus.

Data Source
AI summary
A cyclone dirt separating apparatus and a vacuum cleaner having the same are disclosed. The cyclone dirt separating apparatus comprises a cyclone body including a first cyclone chamber in which dirt is separated preliminarily from air drawn in from an exterior by a centrifugal force; and a second cyclone chamber in which dirt is separated secondarily from the air discharged from the first cyclone chamber; and a dirt collecting case coupled to a lower end of the cyclone body for collecting the dirt. Also, the cyclone dirt separating apparatus further comprises a discharge guide duct passed through the cyclone body and the dirt collecting case and guiding the air discharged from the second cyclone chamber. Therefore, the air discharged through the discharge guide duct is directly entered to a motor mounting space of the vacuum cleaner.
