AI Technical Summary

Technical Problem

Existing cleaning units for teatcups of milking apparatuses face issues with dirt and microorganism buildup in the cup-shaped member, particularly at the corner between the annular bottom surface and the side surface, leading to hygiene concerns and potential contamination.

Method used

The cleaning unit features curved ribs that extend from the inner to the outer position, forcing cleaning liquid to rotate and reach all areas, including the corner, preventing agglomerations, and is designed with an annular bottom surface perpendicular to the longitudinal central axis and a supply rod member for efficient liquid distribution.

Benefits of technology

This design ensures thorough rinsing of the teatcup surfaces, preventing dirt and microorganism buildup, maintaining hygiene and preventing contamination by ensuring all areas are effectively cleaned.

Abstract

A cleaning device comprises cleaning units (3) for cleaning teatcups (7). The cleaning unit receives a teatcup and comprises a cup-shaped member (10). One problem of the known cleaning units is that dirt and other particles, such as microorganisms, may collect and build up agglomerations in the cup-shaped member, in particular in the corner between the annular bottom surface and the side surface, and at various types of protrusions for creating a gap or a distance between the cup shaped member and a surface of a teatcup received therein for enabling cleaning fluid to reach outer surfaces of the teatcup. Such agglomerations may deteriorate the hygienic condition of the cleaning unit, and in a worse case result in contamination of the teatcup. Ribs are a possible type of protrusions for creating said gap or distance, but also when using ribs, there is a risk that particles build up agglomerations. The cup-shaped member comprises an annular bottom surface (12) extending around a longitudinal central axis (x) of the cleaning unit,and aside surface (13) extending around the annular bottom surface and facing the longitudinal central axis. Ribs (14) protrude from the annular bottom surface and have an extension between an inner position (A) and an outer position (B) on the annular bottom surface. The inner position is located more closely to the longitudinal central axis than the outer position. The ribs are configured to create a gap (15) between the annular bottom surface and an end surface (8) of a teatcup received in the cleaning unit. Each of the ribs is curved along at least a part of the extension. The curved ribs allow for efficient rinsing of the cup-shaped member by inducing a vortex like rotation of the cleaning fluid in the cleaning unit that will also reach the corner between the annular bottom surface and the side surface. This prevents any build-up of agglomerations of dirt and other particles.
