Definitions
- the invention relates to methods for controlling the dosage of detergents in multi-stage washing machines with at least one dispenser and a control device for performing such methods.
- Multi-stage or multi-bath washing machines perform at least two of the pre-wash, main wash, rinse, rinse, fabric rinse, post-acid, neutralize, disinfect, dry, etc. stages. For some of these work stages, detergents or auxiliary washing agents are required, which are also automatically washed into automatic washing machines. For this purpose, there is generally one washing-in chamber per stage, the control of the washing machine ensuring the delivery of water for washing in the detergents or washing aids into the respective washing-in chamber.
- 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 and separate systems, for the connection of which an intervention in the washing machine control system is required. Such systems are complex and the systems, even if they take all functions into account in an integrated manner from the start, are very expensive.
- Electronizing the control system enables convenient systems at falling prices, but retrofitting dosing systems is particularly complicated and time-consuming due to the necessary intervention in the washing machine electronics.
- the technical problem on which the invention is based is to develop a metering control which operates without intervention in the washing machine control and which enables automatic metering of detergents in a simple and uncomplicated manner.
- Such a metering control has the advantage that it can be installed in the simplest way without intervention in the washing machine or the metering system.
- a moisture sensor has to be arranged in the induction chambers, for the associated washing stage of which automatic dosing of detergents or washing aids is desired.
- the signal from such a sensor when injecting detergent water is to be forwarded to the dosage for the detergent in question.
- the signal connection is blocked after the first signal contact until it is activated again.
- an at least two-stage quantity regulator is used in a further process variant.
- a simple amount can be specified in two stages, little / much or three stages, little / medium / much.
- this flow regulator is set manually.
- the control device for the dosing of detergents is so simple and straightforward that it can be installed even without the use of qualified personnel, even when the device is retrofitted.
- the washing machine control which is not affected by this installation, ensures that induction water is conveyed into the respective induction chamber before the next washing stage.
- the start signal is passed on to the dosing system and the respective detergent is conveyed into the induction chamber with the wetted sensor.
- a moisture sensor can consist of a simple cable with two exposed poles, which generate a signal when wetted.
- a device is expediently provided which ensures that only one dosing process per washing stage is triggered during a washing machine cycle. Otherwise, this could be the case for a situation in which the induction water is pumped into the induction chamber over a longer period of time than for Dosing of the detergent is necessary to trigger the dosing process again.
- Such a device can advantageously consist of an activator which can be connected upstream of the metering system with the signal line and which interrupts the line after the first signal contact and can only be activated again when a new machine cycle is started.
- a volume controller for example with the settings little / much or little / medium / much, can also be designed as a separate module together with the signal line. This controller is then connected to the dosing control with the signal line and can then ensure the delivery of a correspondingly predetermined amount.
- Fig. 1 shows schematically the connection of induction chambers of a washing machine with a separate metering system
- Fig. 2 shows the representation of a dispenser in a detailed schematic representation.
- a washing machine 1 is shown schematically, in which three detergent dispensers 2 for detergents or washing aids are schematically arranged on the upper right front corner.
- the induction water 5 is conveyed through the washing machine control unit via the induction nozzle 4.
- the induction water 5 wets the moisture sensor 7, which forwards a corresponding signal to the signal input 11 of the dosing device or the dosing system 10 via the signal line 8.
- the signal input 11 is assigned an activator 13 which, after the first signal contact per wash cycle Signal line interrupts and is only reactivated when a new machine cycle is started.
- the metering system 10 controls the delivery of a corresponding amount of detergent through a metering line 6 to the metering outlet 9 at the dispensing chamber 2. This amount can be predetermined by a volume controller 12.
- the detergent enters the induction chamber 2 and is injected into the induction funnel 3 by the induction water 5 emerging from the induction nozzle 4 and from there into the washing or treatment drum.
- the quantity regulator 12 and activator 13 shown in FIG. 1 within the dosing device 10 can also easily be connected upstream of the dosing device 10 if these functions were not present in the dosing device 10 from the start.
- a dispensing chamber 2 illustrated again in detail in FIG. 2 can be implemented in a variety of ways. However, it must enable the basic functions described.
- individual metering lines 6 can be drawn between the metering chamber connection and metering outlet 9, as shown in the drawing.
- the individual connections can also be switched via pipe manifolds, so-called manifolds, and a common line between them.
- the flow directions for signals and media are indicated by arrows on the feed line for the induction water 5, the signal line 8 and the metering line 6 and on the pipeline arranged under the induction funnel 3.
