Cyclone Robot Cleaner Layout for Larger Dust Box Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot cleaners have a small dust box capacity due to their low vertical height, leading to frequent emptying and reduced suction force from accumulated dust, which inconveniences users and affects cleaning efficiency.
Innovation Solution
A robot cleaner design featuring a cyclone unit with multiple cyclones and guiding members for efficient dust filtration, a dust box accommodated between guiding members for increased capacity, and a fan unit for external air discharge, enhancing cleaning performance and spatial efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot cleaner is designed with low vertical height to fit under furniture, then it can access more cleaning areas, but the dust box capacity becomes small
Solution Approach 1:
The dust box is designed with an extended portion that protrudes forward from the main body in the horizontal direction, utilizing the horizontal space between the guiding members rather than only vertical space. This dimensional change allows increased dust box capacity while maintaining the low vertical height profile needed to fit under furniture.
2Length of stationary object
If the dust box has small capacity, then the cleaner body can maintain low height, but the dust box needs frequent emptying
Solution Approach 1:
The dust box utilizes horizontal space by extending forward between the guiding members, converting vertical height constraints into horizontal space utilization. This increases dust box capacity without increasing the cleaner body height, thereby reducing the frequency of emptying operations.
3Length of stationary object
If the dust box has small capacity, then the cleaner body can maintain low height, but suction force decreases due to accumulated dust
Solution Approach 1:
The dust box extends horizontally between the guiding members to increase capacity, allowing more dust to be stored before suction force decreases. This dimensional approach maintains the low profile needed for furniture clearance while extending the operational duration between emptying cycles.
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 design effectively filters dust from air, reduces the need for frequent dust box emptying, maintains suction force, and provides an enhanced cleaning function within a restricted space.
Implementation Method 1
a cyclone unit provided at a rear upper side of the suction unit, the cyclone unit having a first suction opening and a second suction opening for sucking air, and the cyclone unit having a first cyclone and a second cyclone for passing air therethrough, the air having dust filtered therefrom by a centrifugal force

AI summary
A robot cleaner includes a cleaner body, a suction unit, and a cyclone unit. The cyclone unit has a first suction opening and a second suction opening for sucking air, and a first cyclone and a second cyclone for passing air therethrough, the air having dust filtered therefrom by a centrifugal force. A first guiding member and a second guiding member extend upwardly from the suction unit toward the cyclone unit with an inclination angle, the first guiding member for connection between the suction unit and the first suction opening, and the second guiding member for connection between the suction unit and the second suction opening. A dust box communicated with a dust discharge opening is provided at a front side of the cyclone unit so as to collect dust filtered by the cyclone unit. The dust box is partially or wholly accommodated between the first and second guiding members.
