Internal Spray Arm Supply Pipe Layout for Leak-Safe Washer Disinfectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic cleaning and disinfection machines are prone to leakage due to external supply lines, which complicates handling and operational safety.
Innovation Solution
The supply pipe is arranged entirely within the washing compartment, eliminating external lines and allowing for a fluid-tight connection between machine-side and basket-side sections, reducing leakage risks and increasing the washing compartment's capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If supply lines are arranged outside the washing compartment, then the usable washing space is maximized, but leakage risks increase and operational safety decreases
Solution Approach 1:
The supply lines are extracted from the external environment and relocated entirely within the washing compartment. The patent implements this by providing a supply pipe that extends along the axis of rotation inside the washing compartment, with a fluid-tight connection between the machine-side and basket-side sections, thereby eliminating external supply lines and their associated leakage risks while maintaining washing space.
2Ease of manufacture
If supply lines are arranged outside the washing compartment, then installation and maintenance are simplified, but leakage risks increase
Solution Approach 1:
The supply pipe is nested within the washing compartment structure, with the basket-side section inserted into the machine-side section in a fluid-tight manner. This nested arrangement integrates the supply lines into the internal structure of the washing compartment, eliminating external connections and their associated leakage risks while maintaining ease of assembly through the modular design.
3Reliability
If the supply pipe is arranged within the washing compartment, then leakage risks are minimized, but the washing compartment capacity may be reduced
Solution Approach 1:
The supply pipe is arranged along the vertical axis of rotation within the washing compartment, utilizing the vertical dimension rather than occupying horizontal washing space. The pipe extends from the machine-side along the axis to the basket-side section, thereby minimizing space occupation while ensuring fluid-tight connections and reducing leakage risks.
4Ease of operation
If external supply lines are used, then coupling to basket-side spray arms is simplified, but water path lengths increase
Solution Approach 1:
The supply pipe is pre-positioned within the washing compartment along the axis of rotation, with the basket-side section ready to be coupled to the machine-side section. This preliminary arrangement within the compartment eliminates the need for long external supply lines, thereby reducing water path lengths while maintaining coupling simplicity through the standardized fluid-tight connection interface.
