Brewing Chamber Rinsing After Capsule Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brewing devices fail to achieve effective rinsing results due to residue contamination from capsules during the brewing process, leading to unsatisfactory cleaning outcomes, especially in the lower areas of the infusion container.
Innovation Solution
A method and device where the capsule is removed before rinsing, allowing rinsing liquid to pass through a lateral opening and be collected, with the brewing chamber moved to a rinsing position to ensure the rinsing liquid hits a guide element and is drained, preventing contamination. The device includes a nozzle with multiple openings for efficient rinsing and a drive mechanism for positioning changes, ensuring thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the capsule remains in the brewing chamber during rinsing, then the brewing chamber can be sealed and structurally simple, but the rinsing liquid becomes contaminated with capsule residues leading to unsatisfactory cleaning results
Solution Approach 1:
The capsule is removed from the brewing chamber before the rinsing process begins. This preliminary action prevents capsule residues from contaminating the rinsing liquid, thereby ensuring high rinsing quality without requiring complex sealed structures or automated removal mechanisms
Solution Approach 2:
The capsule is extracted from the brewing chamber prior to rinsing. By taking out the capsule before the rinsing operation, the system avoids the technical contradiction of maintaining capsule presence for structural simplicity versus achieving clean rinsing results
2Manufacturing precision
If cleaning agent is introduced into the brewing chamber before capsule removal, then the brewing chamber structure remains simple, but the cleaning result is unsatisfactory due to contamination of rinsing liquid with infusion beverage residues
Solution Approach 1:
The capsule is removed before introducing cleaning agent or rinsing liquid into the brewing chamber. This sequence ensures that the rinsing liquid remains pure and effectively cleans the chamber without being contaminated by infusion beverage residues from the capsule
Solution Approach 2:
Instead of introducing cleaning agent first and then removing the capsule (which causes contamination), the process is inverted: the capsule is removed first, then cleaning agent is introduced, ensuring effective cleaning without contamination
3Duration of action of stationary object
If the brewing chamber is rinsed immediately after brewing, then tea brewing quality is maintained by avoiding drying out, but capsule residues contaminate the rinsing liquid unless the capsule is removed first
Solution Approach 1:
The capsule is removed as a preliminary step before immediate rinsing of the brewing chamber. This allows the chamber to be rinsed immediately after brewing to prevent drying out and maintain tea freshness, while ensuring the rinsing liquid remains pure without capsule residue contamination
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
This approach ensures improved rinsing results by preventing capsule residue contamination and allowing immediate cleaning post-brewing, particularly beneficial for tea brewing, with reduced liquid loss and enhanced cleaning efficiency.
Implementation Method 1
a nozzle having a plurality of openings distributed over the circumference being provided on the inlet. As a result, both hot water for initiating the brewing process and hot water for a rinsing process can be introduced via the nozzle
Implementation Method 2
The injection of rinsing liquid above the lateral opening leads to only small losses of rinsing liquid at the lateral opening, since part of the rinsing liquid film flows around the opening. In addition, the injection of rinsing liquid above the lateral opening leads to only small losses of rinsing liquid at the lateral opening, since part of the rinsing liquid film flows around the opening. In addition, the parabolic upper area of the brewing chamber and enables a very good rinsing result
Implementation Method 3
the brewing chamber is moved together with a filler neck in order to move the filler neck from a filling position above a passage for filling the vessel into a rinsing position above a guide element in order to then rinse the brewing chamber. This ensures that the rinsing liquid hits the guide element and can be drained from there into a collection basin
