Household-type water-recirculating clothes washing machine with automatic control of the washload weight, and operating method thereof

摘要

Household-type front loading and water-recirculating clothes washing machine adapted to automatically measure the weight of the dry clothes loaded in the machine for washing, also on the basis of the information on the type of clothes in said washload entered from the outside (user), in which the measurement of such weight of the washload is performed by measuring the amount of water that is absorbed by the clothes in the washload when this is soaked with water to a point at which it is in a dynamic saturation, i.e. steady-state condition. Said measurement of the amount of water absorbed in the clothes is obtained by subtracting the amount of water that is present in the machine, and that does not interact with the washload, from the total amount of water let into the wash tub. The weight of the load of clothes is finally calculated by processing and interpolating the amount of absorbed water and rectifying such value with an information on the properties of the clothes in the washload.
