Surface-Cleaning Head With Fixed Nozzles for Uncovered-Area Rinsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning heads do not achieve optimal cleaning results due to limitations in the distribution and application of cleaning fluid, particularly in covering and rinsing areas not directly under the housing.
Innovation Solution
The surface cleaning head incorporates additional nozzles that are fixed against rotation, allowing for the application of cleaning fluid to both covered and uncovered areas, with varying flow rates and angles to enhance cleaning effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only rotatable cleaning nozzles are used under the housing, then the cleaning action is concentrated on the covered area, but the uncovered areas cannot be effectively rinsed
Solution Approach 1:
The cleaning system is segmented into two functional groups: rotatable cleaning nozzles under the housing for intensive cleaning of covered areas, and fixed additional nozzles on the housing for rinsing uncovered areas. This segmentation allows each nozzle type to perform its specialized function effectively, resolving the contradiction between concentrated cleaning action and comprehensive coverage.
Solution Approach 2:
The surface cleaning head is designed with multi-functionality by incorporating both rotatable cleaning nozzles and fixed additional nozzles that can be selectively activated. This allows the same device to perform both intensive cleaning of covered areas and rinsing of uncovered areas, achieving universal cleaning effectiveness across all surface zones.
2Productivity
If pressurized cleaning fluid is supplied to multiple nozzles simultaneously, then all areas are cleaned at once, but the cleaning fluid pressure is distributed and reduced
Solution Approach 1:
The system incorporates a selective supply mechanism that dynamically controls which nozzles receive pressurized cleaning fluid based on operational requirements. The control unit can activate only the rotatable cleaning nozzles for intensive cleaning, or add the fixed additional nozzles for rinsing, thereby maintaining high pressure concentration while achieving comprehensive cleaning coverage through dynamic configuration.
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 enables improved cleaning by effectively loosening and rinsing dirt from both covered and uncovered areas, enhancing the overall cleaning efficiency and coverage of the surface.
Implementation Method 1
The at least one cleaning nozzle can be subjected to pressurised cleaning liquid and rotates together with the spray arm about the rotation axis in order to apply a jet of cleaning liquid to an area of a surface to be cleaned
Implementation Method 2
a jet of cleaning fluid onto the area currently covered by the housing, removing dirt from the surface to be cleaned
Implementation Method 3
When the jet of cleaning fluid is released, the cleaning nozzle mounted on the spray arm experiences a recoil, which causes the spray arm and cleaning nozzle to rotate around their axis

AI summary
The invention relates to a surface-cleaning head (10) for cleaning a surface, having a hood-shaped housing (12) which is open at the bottom in a horizontal position of use of the surface-cleaning head (10) and which has a working chamber (20) in which at least one spray arm (104, 106) having a spray nozzle (108, 110) is rotatably mounted about an axis of rotation (112), wherein a cleaning liquid under pressure can be applied to the cleaning nozzle (108, 110) and the latter revolves about the axis of rotation (112) together with the spray arm (104, 106) in order to apply a cleaning liquid jet to a region of a surface to be cleaned that is covered by the housing (12) during the use of the surface-cleaning head (10). The aim of the invention is to develop the surface-cleaning head (10) in such a way that the surface-cleaning head achieves an improved cleaning result. This aim is achieved, according to the invention, in that the surface-cleaning head (10) has at least one rotationally fixedly held additional nozzle (138), wherein a cleaning liquid jet can be applied by the at least one first additional nozzle (138) to a region of the surface to be cleaned that is not covered by the housing (12) during the use of the surface-cleaning head (10)
