Definitions
- the present invention relates to a laundry care device with a control.
- laundry care appliances such as In a washing machine
- wash liquor is supplied to the tub during a washing process to achieve adequate wetting of the laundry in the laundry drum.
- the determination of the volume of wash liquor present in the tub is crucial to ensure an effective laundry care process. Too little wash liquor volume in the tub does not result in adequate wetting of the laundry, while too large a wash liquor volume on the other hand leads to a large consumption of wash liquor.
- EP 2 202 343 A1 describes a washing machine with a sensor for determining a level and / or a hydrostatic pressure of an aqueous liquid present in a washing machine's washing tub.
- a laundry care apparatus having a pumping system comprising a laundry drum for receiving laundry, a washing liquor receptacle, the tub comprising an inlet opening and a drain opening, a conduit defining the inlet opening and the outlet opening and a pump for pumping wash liquor through the conduit, comprising a load detecting means for detecting a weight of laundry in the laundry drum, having a power detecting element for detecting an electric power Performance of the pump, with a Waschlaugenzu operationselement for supplying a volume of wash liquor into the tub, and with a control, solved, wherein the control is formed, a bound to the laundry in the laundry drum amount of wash liquor depending on the supplied volume of wash liquor and in response to the detected electric power value of the pump, and wherein the control is configured to change a laundry care program depending on the ratio of

- the control can advantageously control the laundry care program depending on the detected laundry weight and depending on the particular type of laundry.
- the weight of the laundry in the laundry drum is determined by the load detection means, such as the laundry. a weighing device detected. Then, a volume of wash liquor is supplied through the wash liquor feed element to the tub. Subsequently, a part of the supplied wash liquor is determined by the control, which is bound to the laundry. From the ratio of the volume of washing liquor bound to the laundry and the weight of the laundry, the control can determine the type of laundry.
- the control element determines the volume of the wash liquor bound to the wash by determining the volume of wash liquor supplied minus the volume of wash liquor that is not bonded to the wash, and therefore is freely movable in the pump-over system.
- the freely movable in the Umpumpsystem wash liquor is pumped out of the tub by the pump in the pumping system.
- the power sensing element senses the electrical power of the pump during the pump down process. When the pump has pumped out in the Umpumpsystem freely moving amount of wash liquor from the tub, air sucked by the pump, which reduces the amount of pumped through the pump wash.
- the power sensing element can detect the end of the pump down process based on a decreasing electrical power value of the pump.
- the control of the detected Abpumpzeitintervall and from the known volume flow of the pump can determine the volume of freely movable in the pumping system wash liquor. Since the control knows the volume of the total, supplied wash liquor, taking into account the particular free-moving volume of wash liquor, the volume of wash liquor bound to the wash can be determined. The ratio of the volume of wash liquor bound to the wash and the weight of laundry detected corresponds to the soak time, a parameter that is characteristic of the fabric type of laundry. The control can automatically determine by a comparison of the determined flooding time with pre-stored for known types of wash flooding times the type of laundry laundry. Based on the particular type of laundry, the control may alter the laundry care program to tailor the laundry care process to the particular type of laundry.
