Definitions

the invention relates to a method for controlling the dosage of detergents in multi-stage washing machines with at least one detergent dispenser, the entry of water into a washing-up chamber of the washing machine without Intervention in the washing machine control the one-time dosing of a predetermined Triggers the amount of detergent.
the invention also relates to a control device for carrying out a method for controlling the metering of Detergents in multi-stage washing machines, in at least one detergent dispenser Washer a moisture sensor arranged and without connection to the washing machine control is connected to a separate dosing system via a signal line and this arrangement is designed such that when water enters a dispensing chamber equipped with the moisture sensor a signal is generated which is processed internally in the dosing control of the separate dosing system and triggers the dosage of a predetermined amount of detergent.
Operate multi-stage or multi-bath washing machines at least two of the pre-wash, main wash, clear wash, rinse, Rinse, acidify, neutralize, disinfect, dry etc.
laundry detergents or laundry aids can also be automatically washed into automatic washing machines.
Detergents or washing aids can be in powder, liquid or paste form. Automatic dosing systems for these agents generally receive their control signals from the control of the washing machine. This applies to both integrated as well as to separate systems for the connection of which an intervention in the washing machine control is required. Such systems are complex and that Systems, even if they have all functions in an integrated manner from the outset take into account very expensive.
the electronization of the control enables comfortable systems to sink prices, but especially the retrofitting of dosing systems by the Intervention in the washing machine electronics required for this is complicated and expensive.
a first water sensor in the induction chamber is a second water sensor Tank provided through which the control device provides information about the Status of the current washing program received. Is the washing program at one reached certain point and then the first sensor shows the inflow of Water in the induction bowl, detergent from the tank into the wash tank metered.
the second sensor is used to dose detergent to avoid, for example, in later rinsing processes. In such Rinsing processes usually also water flows into the induction chamber and from there into the wash tank. Reaching this rinse level is indicated by detects the second sensor and forwards it to the control device for metering locks of detergent in this stage of the wash program, although the first Sensor signals the presence of water inside the induction bowl.
the object of the invention is a method according to the preamble of Claim 1 and a device according to the preamble of claim 5 develop, the device much easier to conventional washing machines grown and especially without the use of qualified personnel can be installed.
Such a metering control has the advantage that it is in the simplest way without Intervention in the washing machine or the dosing system can be installed.
a moisture sensor is to be arranged in the induction chambers for their associated washing level an automatic dosage of detergents or Washing aids is desired.
the signal from such a sensor when injecting of induction water depends on the dosage for the detergent in question forward. To ensure that a detergent is used only once per wash is dosed, the signal connection after the first signal contact up to one reactivation blocked.
the control device according to the invention for dosing detergents is so simple and straightforward that it can be qualified even without using it Personnel can be installed, even when retrofitted.
the of This installation of pristine washing machine controls ensures that each before the next washing stage, induction water into the induction chamber concerned is promoted. As soon as this induction water wets the moisture sensor, it will Start signal is passed on to the dosing system and the respective detergent conveyed into the induction water with the wetted sensor.
a humidity sensor can in the simplest case from a simple cable with two exposed Poles exist that generate a signal when wetted.
a device which ensures that during a washing machine cycle only one dosing process per washing stage is triggered. This could otherwise, in a situation where the induction water is used for an extended period of time is fed into the induction bowl as time for the Dosage of the detergent is necessary to trigger the Perform dosing.
Such a device can advantageously an activator that can be connected upstream of the dosing system with the signal line exist, which interrupts the line after the first signal contact and only with the start of a new machine cycle can be reactivated.
volume controller for example with the settings little / much or little / medium / high, can be used as a separate module together with the signal line be conceived. This controller is then connected to the signal line Dosing control connected and can then be used to promote a ensure according to the specified amount.
a washing machine 1 is shown schematically, in the schematic on the right upper front corner three induction compartments 2 for detergent or Washing aids are arranged.
the Detergent water 5 wets the moisture sensor 7, which is via the signal line 8 corresponding signal to the signal input 11 of the doser or Dispensing system 10 passes on.
An activator 13 is the signal input 11 assigned to the after the first signal contact per wash cycle Signal line interrupts and only when a new one is started Machine cycle is reactivated.
the dosing system 10 controls the conveyance of a corresponding one Amount of detergent through a metering line 6 to the metering outlet 9 at the Detergent dispenser 2. This quantity can be predetermined by a quantity regulator 12.
the detergent enters the dispenser 2 and is removed from the The induction nozzle 4 escaping induction water 5 into the induction funnel 3 and from there washed into the washing or treatment drum.
the flow regulator 12 and shown in Fig. 1 within the meter 10 Activator 13 can also be separated from dosing device 10 in a simple manner are connected upstream if these functions are not in the dosing device 10 were there in advance.
a induction chamber 2 can be implemented in a variety of ways. She must however, enable the basic functions described. So at Arrangement of several induction chambers, each with individual metering lines 6 be drawn between the metering chamber connection and metering outlet 9, like this is shown in the drawing. But it can also be the individual Connections via pipe manifolds, so-called manifolds, and one intermediate common line can be switched. On the supply line for the induction water 5, the signal line 8 and the metering line 6 as well the piping arranged under the induction funnel 3 are indicated by arrows Flow directions for signals and media specified.
