Beverage Outlet Venting and Flow Guiding to Reduce Splashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage preparation machines, especially coffee machines, experience splashing and unrest in the beverage stream due to air inclusions, leading to soiling and undesirable effects like brown scattering spots on milk froth.
Innovation Solution
The beverage outlet features three or more incisions on the outlet pipe face side for lateral air discharge and a radially extending beverage guiding element with wings to calm and center the stream, reducing bubble formation and splashing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a beverage guiding element with a second section protruding from the outlet opening is used to calm the beverage stream, then the stream stability is improved, but air inclusions remain trapped causing splashing and turbulence
Solution Approach 1:
The patent extracts the harmful air inclusions from the beverage stream by providing escape openings in the outlet pipe that allow air to exit laterally before reaching the beverage guiding element, preventing air bubbles from being carried into the calmed stream
Solution Approach 2:
The outlet pipe is segmented into functional zones: a first section with escape openings for air discharge, and a second section containing the beverage guiding element for stream calibration, allowing independent optimization of air removal and stream stabilization functions
2Stability of the object's composition
If the outlet pipe has a larger inner diameter to calm the beverage stream, then the stream stability is improved, but the device complexity increases
Solution Approach 1:
The outlet pipe is designed as a multi-functional component that simultaneously serves as the beverage conduit, the air escape pathway (through integrated escape openings), and the structural support for the beverage guiding element, eliminating the need for separate air venting mechanisms
Solution Approach 2:
The escape openings are directly formed in the outlet pipe wall, merging the air venting function into the existing outlet pipe structure rather than requiring a separate air vent component, thereby reducing overall device complexity
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 minimizes splashing and turbulence by allowing air to escape quickly, reducing bubble formation, and guiding the beverage stream to emerge smoothly, minimizing soiling and improving the presentation of beverages.
Implementation Method 1
The outlet pipe (110, 210) has three or more incisions (115, 215) extending on the face side from the end (112, 212) on the outlet opening side counter to the beverage dispensing direction D, wherein each of the incisions (115, 215) forms a through-opening between the inner and outer area of the outlet pipe (110, 210)
Implementation Method 2
a beverage guiding element (220) having a central axis (M) coinciding with a central axis of the outlet pipe (210), the beverage guiding element (220) having three or more wings (223) extending radially outwards from the central axis (M) of the outlet pipe (210)

AI summary
The invention relates to a beverage outlet (1) for a beverage preparation machine, for example for a coffee machine, with an outlet pipe (210) which can be connected to the beverage preparation machine at one end and an outlet opening (211) at the other end (212) for dispensing a beverage from the beverage preparation machine having. Furthermore, the beverage outlet (1) has a beverage guide element (220) running coaxially to the outlet pipe (210), which is arranged with a first section (221) inside the outlet pipe (210) and with a second section (222) from the outlet opening (211 ) of the outlet pipe (210) protrudes. It is provided that the outlet tube (210) has at least one incision (215) extending on the face side from the end (212) of the outlet tube (210) on the outlet opening side in the opposite direction to the beverage dispensing direction (D) and which has a through-opening between the inner and outer area of the outlet tube ( 210) forms.
