Problems solved by technology
These disadvantages relate, for example, to the required housing dimensions, which are disadvantageous for embodiments where only limited installation space is available
Due to this size, a throughflow measuring device of the type described can therefore sometimes not be arranged in the beverage preparation machine where it is actually desired, but only where sufficient installation space is available

Embodiment Construction
[0021] In the illustrated exemplary embodiment, the throughflow measuring device 1 for detecting the volume of liquid delivered by the pump is integrated in the water connection module 2 . The water connection module 2 includes a housing 3 . The housing 3 is of substantially cylindrical design and has a water inlet 4 , which is an upper opening of the housing 3 in the illustrated exemplary embodiment. A water line connection part of the water supply, for example a hose part connected to a water storage container, is inserted into the water inlet 4 or into an opening provided for this purpose through the housing 3 . The hose part seals via its outer wall against the inner wall of the housing 3 . The water outlet 5 of the water connection module 2 is in the form of a nozzle. When the water connection module 2 with its through-flow measuring device 1 is used in a beverage preparation machine such as a coffee machine, the suction hose connected to the pump is mounted on the outl...

The present invention concerns a throughflow measurement device for a beverage preparation machine for measuring the liquid delivered by means of a pump for beverage preparation, comprising a housing (3) which encloses a throughflow pathway, a rotary body (7) which is mounted within the housing (3) and which is driven by liquid delivered through the flow pathway and which has at least one encoder element (10, 10.1), and comprising a receiver unit (19) which is situated outside the housing (3) which encloses the throughflow pathway, said receiver unit being arranged so as to receive the signals from the at least one encoder element (10, 10.1), characterized in that the rotary body (7) has at least one drive body (9) which is arranged with its water-struck side inclined with respect to the longitudinal extent of the axis of rotation of the rotary body (7), and in that the housing (3) which encloses the throughflow pathway of the throughflow measurement device (1) is part of a module which exhibits further functionality, for example a water connection module (2), or of an assembly.
Description
technical field [0001] The invention relates to a throughflow measuring device for a beverage preparation machine for measuring a liquid conveyed by means of a pump for beverage preparation, comprising a housing enclosing a flow path / throughflow path; a rotating body mounted in the housing and driven by the liquid conveyed through the flow path and having at least one encoder element; and a receiver unit located in a housing enclosing the flow path Outside the body, the receiver unit is arranged to receive signals from the at least one encoder element. Background technique [0002] Beverage preparation machines, such as coffee machines, especially in the form of so-called fully automatic machines, have a through-flow measuring device for detecting the flow of liquid delivered by the pump. This information is required for beverage preparation. A pump delivers water from a storage container to a thermal block set up to heat the water. By using the through-flow measuring dev...
