Suction pick-up apparatus for a flushing box of a washing machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing siphons for washing machine dispensers face issues with capillary effects and require significant installation space, particularly due to the design involving an inner tube and siphon cap.
Innovation Solution
A siphon design comprising two separate parts forming a U-shaped tube with a horizontal dividing plane above the storage level, avoiding capillary effects and reducing installation space by separating the mold horizontally, allowing for a form-fitting connection and easy demolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a siphon is designed with an inner tube and siphon cap, then the siphon can be formed as a complete unit, but the outlet requires a certain amount of installation space and capillary effects occur in the area of the siphon
Solution Approach 1:
The siphon is divided into two separate parts (first siphon part and second siphon part) that can be connected to each other. The dividing plane between these parts runs at least partially above the filling level, allowing each part to be smaller and reducing the overall installation space required while maintaining the complete siphon function.
2Reliability
If a siphon is designed with an inner tube and siphon cap, then the siphon can be formed as a complete unit, but capillary effects occur in the area of the siphon
Solution Approach 1:
By separating the siphon into two parts with a dividing plane above the filling level, the patent eliminates the formation of a continuous capillary path from the suction opening through the siphon to the outlet opening, thereby preventing capillary effects that would otherwise occur in a complete siphon structure.
3Object-generated harmful factors
If the siphon parts are separated with a dividing plane above the filling level, then capillary effects are avoided, but the connection between parts must be ensured
Solution Approach 1:
The first siphon part and second siphon part are designed to be connected to each other, with one part nested or joined to the other, forming a complete siphon when assembled. This nesting connection allows the parts to be manufactured separately to avoid capillary effects while ensuring proper connection during assembly.
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 effectively prevents capillary effects and reduces installation space requirements while ensuring stable operation and easy removal of the siphon components, enhancing the overall efficiency and usability of the siphon in washing machines.
Implementation Method 1
capillary effects in the area of the siphon can be avoided by separating the mold above a storage level of the dispenser box

AI summary
The invention relates to a siphon (400) for a detergent dispenser of a washing machine. The siphon (400) comprises a first siphon part (402) and a second siphon part (404), wherein the first siphon part (402) and the second siphon part (404) are connected or connectable to each other to form a tube with an inlet opening (408), an outlet opening (412) and a transition bend (416) arranged between the inlet opening (408) and the outlet opening (412), such that a dividing plane (420) between the first siphon part (402) and the second siphon part (404) in the operating state of the siphon (400) runs at least partially above a level level (422) representing a maximum fill level of the detergent dispenser (100) and/or intersects the transition bend (416).
