Dust Chamber Filter Frame With Air Ducts for Stable Vacuum Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners experience reduced suction power when the dust bag is partially filled, as dust accumulation obstructs the air flow to the dust chamber filter, potentially allowing dust to enter the suction compartment and affect the suction means.
Innovation Solution
A frame with air ducts and entry windows is designed to guide air from the dust chamber to the dust chamber filter, maintaining suction power by preventing dust bags from obstructing the air flow and ensuring dust is retained, with features like ribs and grooves that maintain a large passage area and prevent clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a dust bag is used to collect dust in the dust chamber, then dust collection capacity is improved, but air flow obstruction occurs when the dust bag is partially filled
Solution Approach 1:
The dust chamber is segmented into multiple air ducts that are distributed around the periphery, each independently guiding air to the filter. This segmentation allows air to reach the filter from multiple paths, reducing obstruction when the dust bag is partially filled.
Solution Approach 2:
Air ducts serve as intermediary channels between the dust chamber and the dust chamber filter. These ducts ensure that air can reach the filter independently of the dust bag's position, maintaining suction power even when the dust bag is partially filled.
2Volume of stationary object
If the dust bag is placed adjacent to the dust chamber filter, then space utilization is improved, but air flow obstruction occurs when the dust bag is partially filled
Solution Approach 1:
The air flow path is segmented into multiple peripheral air ducts that bypass the central dust bag area. This allows the dust bag to occupy central space while air flows through distributed peripheral channels, maintaining both space utilization and air flow.
Solution Approach 2:
Air ducts are arranged in a peripheral distribution pattern around the dust bag, transitioning from a single central air path to a multi-dimensional peripheral network. This allows the dust bag to occupy the central volume while air flows through the peripheral dimension.
3Productivity
If air ducts are provided for guiding air to the dust chamber filter, then suction power is maintained, but device complexity increases
Solution Approach 1:
The frame structure is designed with multi-functionality, where the same frame that provides structural support also incorporates the air ducts as integral components. This eliminates the need for separate air duct components, reducing overall device complexity while maintaining suction power.
Solution Approach 2:
The air ducts are merged with the frame structure, combining the support function and air guiding function into a single integrated component. This reduces the number of separate parts and simplifies the overall device structure while maintaining effective air flow.
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 frame ensures consistent suction power even when the dust bag is partially filled by maintaining a large air passage area and preventing dust from entering the suction compartment, thus optimizing the vacuum cleaner's performance.
Implementation Method 1
The frame has air ducts for guiding air from the dust chamber to the dust chamber filter
Implementation Method 2
The dust compartment filter prevents such dust in the dust compartment, which is outside the dust bag, from getting into the suction medium compartment

AI summary
The invention relates to a frame for or with a dust chamber filter for a vacuum cleaner. The invention further relates to a vacuum cleaner, in particular a canister vacuum cleaner, with such a frame. The frame has air channels for guiding air from the dust chamber of a vacuum cleaner to the dust chamber filter or the dust chamber filter side. A vacuum cleaner with this frame is able to maintain its suction power even when its dust bag is already partially filled with dust.
