Vacuum Intake Port Layout for Short-Path Steam Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional steam cleaners lack a vacuum cleaning function and suffer from reduced steam pressure and temperature due to lengthy steam flow paths, necessitating higher settings that increase costs and reduce cleaning effectiveness.
Innovation Solution
A vacuum cleaner with an integrated intake port unit that includes a steam generator within the housing, separating steam and vacuum passages to maintain steam pressure and temperature, allowing for simultaneous vacuum and steam cleaning with a reduced steam flow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the steam generator is provided within the unit 10 and steam is carried to the head part 50 via the connecting hose 40, then the steam cleaning function can be achieved, but the flow path becomes lengthy causing reduced steam pressure and temperature
Solution Approach 1:
The invention divides the cleaning system into two separate functional units: a vacuum cleaner unit for air suction and a steam generator unit for steam production. By segmenting the steam generation and delivery function from the vacuum unit, the steam flow path is minimized and confined to a short distance within the steam generator unit housing, thereby preserving steam temperature and pressure.
Solution Approach 2:
The steam generator unit housing serves as an intermediary structure that integrates both the steam generator and the discharge port in close proximity. This intermediary housing provides a direct, short flow path for steam from the generator to the discharge port, eliminating the need for long external hoses and preventing excessive temperature drop.
2Adaptability or versatility
If the steam generator is provided within the unit 10, then the steam cleaning function can be achieved, but the steam pressure and temperature must be set higher to compensate for pressure loss, raising product and operation costs
Solution Approach 1:
By separating the steam generation function into a dedicated unit with a short internal flow path, the system minimizes energy loss during steam transport. This segmentation allows the steam generator to operate at lower, more efficient pressure and temperature settings while still delivering effective steam to the discharge port.
Solution Approach 2:
The invention converts the potential harm of pressure loss over long distances into a benefit by designing a compact steam generator unit where the short flow path actually enhances efficiency. The condensed water collection system also converts waste condensate into a beneficial resource by recycling it back to the steam generator.
3Ease of operation
If a separate vacuum cleaner is used in addition to the steam cleaner, then normal vacuum cleaning can be performed, but the device complexity and cost increase
Solution Approach 1:
The invention creates a multi-functional cleaning system where a single integrated unit provides both vacuum cleaning capabilities (through the connected vacuum cleaner) and steam cleaning capabilities (through the built-in steam generator). The steam generator unit serves as a universal platform that can work independently for steam cleaning or in conjunction with a vacuum cleaner for combined cleaning tasks, eliminating the need for two separate devices.
