Detergent dispensing system for clothes washing machine or the like
First Claim
1. A detergent dispensing system for a clothes washing machine, comprising:
- (a) a single detergent container for selectively containing one of a plurality of kinds of powdered detergents which differ from one another in degree of detergency;
(b) discharging means associated with the single detergent container so that a powdered detergent contained in the detergent container is discharged to an area communicating to a washing member while in a washing operation;
(c) driving means for driving said discharging means so that said discharging means performs a detergent discharging operation;
(d) a manually operated switch operatively associated with a plurality of displays corresponding to the detergency degrees of the plurality of powdered detergents to be selectively contained in the detergent container, said manually operated switch generating a signal in accordance with a desirable detergency degree when any one of the displays is selected; and
(e) control means comprising a microcomputer provided with a storage unit having a data table for storing data of detergent feed amount in accordance with the respective degrees of detergency of the detergents to be selectively contained in said detergent container, said microcomputer operating to read out said data from the data table in response to the signal supplied thereto from the manually operated switch, thereby controlling the driving means so that an amount of detergent defined by the data read out is discharged.

Abstract
A detergent dispensing system for clothes washing machines consists of a detergent containing hopper having a detergent discharging passageway having the section of approximately semicircular configuration and formed at the bottom portion, a spiral coil arranged in the detergent discharging passageway and discharging the powdered detergent contained in the hopper by screw action caused by its rotation so that the powdered detergent is dispensed to a wash tub of a clothes washing machine, an electric motor for driving the coil, a first manually operated switch for inputting data of a kind of the powdered detergent to be dispensed, a second manually operated switch for inputting data of degree of soil of clothes to be washed, a third manually operated switch for inputting data of a water level to set the water level in the wash tub, and a controller for controlling the rotation speed of the coil so that the amount of the powdered detergent to be dispensed takes a value in accordance with the kind of the powdered detergent, the degree of soil of the clothes to be washed and the water level the data of which are supplied from the first, second and third manually operated switches respectively.
