Hand-Held Floor Cleaner With Integrated Suction and Roller Wiping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held floor cleaning machines do not effectively combine suction and wiping functions to achieve optimized cleaning results while being easy to handle.
Innovation Solution
The design incorporates a cleaning roller with a mouth wall that protrudes into its bristles, creating a suction flow for effective dirt removal, and a wiping function with a cleaning liquid dispenser, along with a sweeping lip for coarse dirt collection, all integrated into a compact, user-friendly device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a mouth wall protrudes into the bristles of the cleaning roller, then suction efficiency is improved, but device complexity increases
Solution Approach 1:
The suction channel device is integrated directly with the cleaning roller such that the mouth wall protrudes into the bristles, merging the suction function with the cleaning roller structure to improve suction efficiency without adding separate components
Solution Approach 2:
The mouth wall extends in the radial direction into the bristle layer, creating a three-dimensional suction path that intersects with the bristle volume, thereby improving suction efficiency by utilizing the vertical dimension within the roller structure
2Object-affected harmful factors
If support wheels are removed to reduce abrasion, then harmful factors are reduced, but ease of operation deteriorates
Solution Approach 1:
The cleaning roller is designed to perform multiple functions: it provides the primary cleaning action through its bristles, supports the entire weight of the device, and enables user control, thereby replacing the traditional support wheels and maintaining ease of operation without causing abrasion

AI summary
The invention proposes a floor-cleaning machine, in particular hand-operated and/or hand-held floor-cleaning machine, which comprises a carrier device, at least one cleaning roller, which is arranged on the carrier device, can be driven in rotation and is provided with a border, also comprises a fan device for generating a suction stream, and further comprises a suction-extraction-channel device which is intended for the suction stream and creates at least one suction-extraction channel with a fluid-active connection between the fan device and the at least one cleaning roller, wherein the at least one suction-extraction channel has at least one mouth cavity in the direction of the at least one cleaning roller and the at least one mouth cavity has a first mouth-cavity wall and a spaced-apart, second mouth-cavity wall, a mouth-cavity opening being formed between said two walls, wherein, in the case of at least one cleaning roller having been placed in position on a floor which is to be cleaned, the first mouth-cavity wall is positioned above the second mouth-cavity wall, as seen in relation to the direction of gravitational force, wherein the first mouth-cavity wall and/or the second mouth-cavity wall butt and/or butts against the border of the at least one cleaning roller or project/projects into the same.
