Abstract
A metering device for metering and supplying media via fluid lines to at least one target apparatus, in particular to a commercial textile washing machine, wherein the metering device has a switching device which is connected on the input side to a metering pump and to a flush pump or to a flushing device and which is connected on the output side to a target apparatus and which can be addressed by a control device of the metering device to change its switch state. The switching device provides a communicative connection between the metering pump and the target apparatus in a first switch state, and, in a second switch state, provides a communicative connection between the flush pump or the flushing device and the target apparatus.

A metering device for metering and supplying media via fluid lines to at least one target apparatus, wherein the metering device comprises a switching device which is connected, on an input side, to a metering pump and to a flush pump, or to a flushing device, and which is connected, on an output side, to a target apparatus, and which can be addressed by a control device of the metering device to change its switch state, wherein the switching device provides a communicative connection between the metering pump and the target apparatus in a first switch state, and provides a communicative connection between the flush pump or the flushing device and the target apparatus in a second switch state.
A method for metering and supplying media via fluid lines to at least one target apparatus, wherein the metering device is connected to at least one container which is filled with a medium, wherein the metering device has a control device with which, in order to perform a metering process, a metering pump and a flush pump or a flushing device can be addressed and a switching device which, in a first switch state, provides a communicative connection between the metering pump and the target apparatus and which, in a second switch state, provides a communicative connection between the flush pump or the flushing device and the target apparatus, comprising the steps of:
- a) addressing the switching device by the control device to switch the switching device to the first switch state;
- b) addressing the metering pump by the control device to take out a predetermined amount of medium from the container and deliver it to a point downstream of the switching device;
- c) addressing the switching device by the control device to switch the switching device to the second switch state;
- and
- d) addressing the flush pump or the flushing device by the control device to deliver the predetermined amount of medium from the point downstream of the switching device to the target apparatus.
A method for metering and supplying media via fluid lines to a plurality of target apparatuses, wherein the metering device is connected to a plurality of containers which are filled with different media, wherein the metering device has a control device, by which a metering pump and a flush pump or a flushing device as well as multiple switching devices can be addressed for performing a metering process, wherein a switching device is assigned in each case to a target apparatus, wherein a switching device establishes a communicative connection in each case in a first switch state between the metering pump and the target apparatus assigned to this switching device and, in a second switch state, provides a communicative connection between the flush pump or the flushing device and the target apparatus assigned to this switching device, the method comprising the steps of:
- e) addressing a first switching device by the control device to switch the first switching device to the first switch state;
- f) addressing the metering pump by the control device to remove a predetermined amount of medium from the container and deliver it to a point downstream of the first switching device;
- g) addressing the first switching device by the control device in order to switch the first switching device to the second switch state;
- h) addressing the flush pump or the flushing device by the control device to deliver the predetermined amount of medium from the point downstream of the first switching device to the target apparatus;
- i) addressing a second switching device by the control device to switch the second switching device to the first switch state;
- j) addressing the metering pump by the control device to remove a predetermined amount of medium from the container and deliver it to a point downstream of the second switching device;
- and
- k) performing step j) before step h) is finished.
A metering device for metering and supplying media via fluid lines to at least one target apparatus, wherein the metering device comprises a switching device which is connected on an input side to a metering pump, a dilution pump and to a flush pump or a flushing device, and which is connected on an output side to a target apparatus, and which can be addressed by a control device of the metering device to change a switch state of the switching device, wherein the switching device provides a communicative connection between the metering pump, the dilution pump and the target apparatus in a first switch state and provides a communicative connection between the flush pump or the flushing device and the target apparatus in a second switch state.
A metering device for metering and supplying media via fluid lines to at least one target apparatus, wherein the metering device comprises a switching device which is connected on an input side to a metering pump and to a flush pump or a flushing device and which is connected on an output side to a target apparatus, wherein the switching device can be addressed by a control device of the metering device to change a switch state of the switching device, wherein the switching device in a first switch state provides a communicative connection between the metering pump and/or a dilution bypass which can be acted upon by the flush pump or the flushing device and the target apparatus, and in a second switch state provides a communicative connection between the flush pump or the flushing device and the target apparatus.
A metering device for metering and supplying media via fluid lines to at least one target apparatus, wherein the metering device has a switching device which is connected on an input side to a metering pump, a dilution bypass, a flush pump or a flushing device and which is connected on an output side to a target apparatus, wherein the switching device can be addressed by a control device of the metering device to change a switch state of the switching device, wherein the switching device in a first switch state provides a communicative connection between the metering pump, the dilution bypass, which can be acted upon by the flush pump or the flushing device, and the target apparatus, and in a second switch state provides a communicative connection between the flush pump or the flushing device and the target apparatus.
