Vacuum Dust Receiver Compartment Layout for Clean Object Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclonic vacuum cleaners face issues with clogged filters leading to reduced suction power and maintenance challenges, as well as the mixing of fine dust from unclogging operations with collected waste, which complicates the recovery of mistakenly sucked objects.
Innovation Solution
A compartmentalized waste recovery tank with a primary compartment for coarse waste and a secondary compartment for fine debris and dust from the unclogging process, featuring an unclogging device driven by a geared motor that operates intermittently to minimize dust suspension and facilitate easy recovery of objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single waste recovery tank is used for both primary and secondary separation waste, then device complexity is reduced and ease of operation is improved, but fine dust from unclogging operations mixes with collected waste making object recovery difficult
Solution Approach 1:
The waste recovery tank is divided into two separate compartments: a first compartment for receiving waste from primary separation (coarse waste) and a second compartment for receiving waste from secondary separation (fine dust). This segmentation prevents mixing of fine dust with collected objects while maintaining a unified tank structure, thus resolving the contradiction between ease of operation and prevention of harmful contamination.
2Reliability
If the unclogging device operates continuously, then filter maintenance is improved, but fine dust becomes suspended and dispersed making recovery harder
Solution Approach 1:
The unclogging device is designed to operate intermittently rather than continuously. The device activates at scheduled intervals to dislodge accumulated dust from the filter, allowing dust to settle into the second compartment during controlled periods rather than creating continuous suspension that would disperse fine particles throughout the tank.
3Volume of moving object
If a compact single-compartment tank is used, then device compactness is improved, but separation of coarse waste and fine dust is lost reducing recovery efficiency
Solution Approach 1:
The tank is segmented into two compartments within a compact overall structure. The first compartment accommodates coarse waste from primary separation while the second compartment collects fine dust from secondary separation and unclogging operations. This internal segmentation maintains compact external dimensions while enabling efficient separation and recovery of different waste types.
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
Enables efficient separation and easy recovery of waste, reduces maintenance complexity by allowing single-operation emptying, maintains compactness, and minimizes user contact with fine dust during maintenance.
Implementation Method 1
a first separation removing the heaviest and most voluminous waste by a bagless device of the cyclonic type
Implementation Method 2
The flow of air in the separation chamber, due to its tangential arrival, and due to its evacuation in the central part of the separation chamber, describes a swirling path favorable to the separation of the waste.
Implementation Method 3
a secondary separation for fine debris and dust by a suitable filter

AI summary
The invention relates to a vacuum cleaner dust receiver (37) comprising a primary separation unit for extracting the heaviest and voluminous wastes by a bagless cyclonic device or by inertia, or by a large meshed grid, wherein the inventive vacuum cleaner also comprises a second separation unit for extracting fine scraps and dust by a suitable filter, which consists of a device for removing a part of retained waste from the filter, and is characterised in that said dust receiver (37) is provided with two separated compartments, i.e. a main compartment for receiving wastes from the first separation unit and a secondary compartment (32) for receiving wastes obtained by the removing device operation.
