Definitions

  • the invention relates to a method for alternately supplying a flushing medium and at least one cleaning medium by means of a metering for at least one laundry cleaning device, wherein the metering is supplied to the flushing medium via a connected to at least one inlet connection Spülmediumszu effet, and the metering with each laundry cleaning device via a respective Waschmediumszu effet with a Output terminal is connected.
  • the invention relates to a cleaning device for carrying out the method according to the invention.
  • each laundry cleaning device is associated with a dosing each. If a user has several laundry cleaning devices, this has the consequence that several dosing systems must be provided.
  • the dosing meet the purpose of supplying a flushing medium and usually several different cleaning media of the respective laundry cleaning device in a defined order.
  • the metering at least two supply lines, which are connected to a laundry cleaning device, namely a Spülmediumszutechnisch and at least one cleaning medium supply line.
  • the cleaning medium is usually pumped by a pump to the laundry cleaning device.
  • Peristaltic pumps are frequently used for this purpose, which mechanically stress the cleaning medium feed line designed as a hose and therefore require the most flexible hoses possible for reliable operation.
  • Detergents that achieve the desired cleaning effect often have the unpleasant side effect of changing the composition of the tubing and thus reducing their service life. This leads to shortened maintenance intervals and to rising operating costs or at worst to a leakage of the supply lines and as a result to a total failure of the laundry cleaning device. Since a plurality of cleaning media is usually used in a washing process, and the cleaning media must be supplied separately from each other in order to avoid undesirable reactions between the cleaning media, in practice, several cleaning medium supply lines be provided with one pump. The variety of these leads not only represents a considerable installation and cost, but also increases the risk of failure of the laundry cleaning device or dosing.
  • the method according to the invention it is possible to supply a laundry cleaning device by means of a single washing medium supply line, which takes over both the supply of the flushing medium and the at least one cleaning medium from the metering to the laundry cleaning device.
  • the number of lines that connect the dosing with the laundry cleaning device can be significantly reduced.
  • the life of the washing medium supply line is significantly higher than that of an equivalent cleaning medium supply line, since cleaning media only during the period in which the laundry cleaning device, a cleaning medium is supplied dwell in the dosing and the washing medium supply line.
  • the subsequent rinsing with the rinsing medium which is preferably water, increases the life of the dosing and the Waschmediumszutechnisch considerably.
  • the cleaning medium is preferably in step d) with the rinsing medium mixed, whereby the cleaning medium passes only in dilute form in the washing medium supply line.
  • the life of the washing medium supply line can be additionally increased.
  • the detection of the cleaning job can be done via a user interface such as a user terminal that can be located on the dosing.
  • a cleaning order can also be transferred from external devices to the dosing system.
  • the dosing system can automatically generate jobs in a manner that can be predetermined by the user.
  • a cleaning job preferably contains the cleaning parameters in which the quantity and the sequence of the media to be supplied to the laundry cleaning device are fixed. Also, the exposure time, the cleaning temperature or the speed of a washing drum can be specified.
  • Rinsing the dosing system in step e) additionally increases the service life of the dosing system or components provided therein, for example, by preventing sticking of mechanically moved or stressed parts.
  • the rinsing process is usually ended by closing at least one participating connection (input connection and / or output connection).
  • the flushing of the dosing system according to step e) of the method according to the invention has the result that valves present in the dosing system are cleaned in a simple manner, which increases their durability and functional life. In the event of failure of a pump, the supply of laundry cleaning equipment can be reliably taken over by the other pump.
  • different cleaning media can be supplied separately from one another by repeating steps d) to e) in an iteration following step e).
  • another cleaning medium in the respective step d) can be supplied to a laundry cleaning device in a single washing medium supply line without the cleaning media coming into contact with one another within the metering system or the washing medium supply line.
  • the amount of cleaning agent to be supplied can be predetermined, for example, by a correspondingly selected pumping capacity of a pump supplying the cleaning agent and optionally the flushing agent.
  • step a) the persistence of the cleaning order for a period of at least 5 seconds can be checked. This prevents a misinterpretation of erroneous signals that could be misinterpreted as a cleaning job.
  • Such faulty signals can be caused by interference or feedback, as they are specifically introduced, for example in the course of a test for electromagnetic compatibility in a system to be tested.
  • the flow rate of the flushing medium is detected in step e).
  • the amount of flushing medium can be determined in a simple manner, which was supplied to a laundry cleaning device in the course of a washing process. If necessary, it is possible to deduce the pumping power of a pump involved, as a result of which a necessary early maintenance can be detected early.
  • the comparison of the pumping power with the flow rate can be used to recalibrate the pump or the period of time in which the flushing medium as well the cleaning media are to be supplied, adapted to a changed pumping power accordingly. This ensures that even with a changed pumping capacity, the desired amount of flushing medium or of cleaning media can be supplied to a laundry cleaning device.
  • the detection can be done for example by an indirect measurement or a direct measurement, for example by means of a measuring wheel / paddle wheel.
  • the difference of the two flow rates can e.g. be used to assess the tightness of the dosing.
  • the availability of the cleaning media is checked and, depending on the result thereof, warning and / or empty messages are output and / or the laundry cleaning device is stopped.
  • the availability of the cleaning media can be checked, for example, by simple sensors which measure the fill level of containers containing said cleaning media. For this purpose, for example, swimming sensors or other level sensors are particularly suitable.
  • the delivery rate of the pumps is measured in step f) and compared with predefinable setpoint values. This allows easy calibration of the pumps and adjustment of the cleaning parameters. Also, a significant deviation from setpoints can be used to infer a faulty state of a pump and any necessary replacement back.
  • the dosing system monitors the state of the laundry cleaning devices connected to the dosing device and the availability of the rinsing and cleaning medium and outputs an error message in the event of deviations from nominal values, which preferably additionally transmits this as an electronic message to a receiving point becomes.
  • a message can be displayed on a terminal or display attached to the dosing system, or a warning light can indicate a deviation from setpoint values.
  • an automatic message for example a text message to a mobile phone of a user, the owner and / or a maintenance team can be sent.
  • the dosing system has a module for producing a radio connection, preferably a W-Lan connection, wherein the dosing system is preferably adapted to be monitored and / or controlled by means of an external communication interface to become.
  • an external communication interface for example, mobile phones, especially smartphones, tablet computers or any other devices can be used with a digital communication interface.
