Abstract
A dosing device for dosing and supplying media via fluid lines to at least one target device, in particular to a textile washing machine, including a control unit, a mixing distribution device with multiple inlets, an outlet and an actuator that can be actuated by the control unit and that switches different communication paths between the inlets and the outlet. The inlets can be connected to containers for the media. A pump arranged downstream of the outlet can be actuated by the control unit as a result of a request command for a medium received from the target device to convey the medium. In a fluid line section downstream of the outlet a pressure sensor is arranged and connected to the control unit.

A dosing device for dosing and supplying media via fluid lines to at least one target device, such as a textile washing machine, comprising:
- a control unit;
- and a mixing distribution device with multiple inlets, an outlet and an actuator that can be actuated by the control unit and that switches different communication paths between the inlets and the outlet in different positions, wherein the inlets can be connected to containers for the media, and wherein a pump arranged downstream of the outlet can be actuated by the control unit as a result of a request command for a medium received from the target device to convey the medium, wherein a pressure sensor is arranged in a fluid line section downstream of the outlet and is connected to the control unit.
A method for operating a dosing device, comprising the steps of:
- a) receiving a request command for a medium from a target device, such as a textile washing machine, by a control unit of the dosing device;
- b) actuating an actuator of a mixing distribution device, which has multiple inlets and an outlet, by the control unit to switch a communication path between an inlet of the mixing distribution device that is connected to a container with the selected medium and the outlet of the mixing distribution device;
- c) receiving information about a line pressure prevailing in a fluid line section downstream of the mixing distribution device by the control unit from a pressure sensor arranged in a fluid line section downstream of the outlet;
- d) actuating a pump arranged downstream of the outlet of the mixing distribution device by the control unit taking into account the received information, in particular reducing a delivery rate of the pump upon detecting or exceeding a threshold value for the line pressure;
- and
- e) conveying the medium in the requested amount to the target device.
An assembly, in particular for a dosing device, comprising a pressure sensor for measuring a line pressure in a fluid line system and comprising a measuring device with which a flow in a fluid line system can be detected and/or with which a presence of a medium in a fluid line system can be detected, wherein the pressure sensor and the measuring device are combined into an assembly.
An arrangement of a pressure sensor for measuring a line pressure in a fluid line system, in combination with a measuring device with which a flow in a fluid line system can be detected and/or with which a presence of a medium in a fluid line system can be detected, wherein the pressure sensor and the measuring device are provided by separate assemblies that are arranged in series with each other, in particular directly adjacent to each other.
A method for analyzing measurement data obtained during the execution of dosing processes by a computing unit, comprising the steps of:
- a) receiving information centrally from a plurality of dosing devices by a device having a computing unit, wherein the information relates to measured line pressures in fluid lines in the respective dosing device or in fluid lines that are arranged downstream of the respective dosing device, in particular in the form of information about a threshold pressure exceedance and/or in the form of information about an occurred pressure anomaly;
- b) comparing the information received from the multiple dosing devices with each other and/or with setpoints or setpoint information for line pressures in fluid lines stored in a memory associated with the computing unit, in particular for the identification of an anomalous dosing device;
- and
- c) checking and/or determining, by the computing unit, whether an intervention is required at a dosing device, in particular at an anomalous dosing device, in particular causing an on-site inspection of an anomalous dosing device.
A device for analyzing measurement data obtained during the execution of dosing processes, wherein the device is configured for a central reception of information from a plurality of dosing devices, wherein the information relates to measured line pressures in fluid lines in the respective dosing device or in fluid lines arranged downstream of the respective dosing device, in particular in the form of information about a threshold pressure exceedance and/or in the form of information about an occurred pressure anomaly, wherein the device comprises a computing unit with which a comparison of the information received from the multiple dosing devices with each other and/or with setpoints for line pressures in fluid lines stored in a memory associated with the computing unit can be carried out, wherein as a result of performing the comparison an anomalous dosing device can be identified by the computing unit, and wherein a check of whether an intervention is required at the anomalous dosing device can in particular be carried out by the computing unit.
