1. Field of the Invention
The present invention relates to a fully-automated washing machine for performing a laundry washing.
2. Description of the Prior Art
Generally, in a conventional washing machine, as illustrated in FIG. 1, a body 1 of a washing machine is disposed with a tub 5 having a washing/spin-drying drum or tank 3 therein and a decelerater 9 is disposed underneath a center of the tub 5 for agitaing the laundry tossed into the washing/spin-drying drum by rotating clockwise and counter-clockwise the stirring blades 7 of a pulsator and the like installed on a floor within the drum 3.
The decelerator 9 is designed to receive a power in order to rotate the stirring blades 7 from a driving means 11 fixed to one end of a lower external side of the tub 5 through a power transfer means 13.
A drainage means 16 such as a solenoid valve and the like is disposed on a middle of a drainage pipe 15 underneath the tub 5 in order to discharge the laundry water in the washing/spin-drying drum to the outside.
Furthermore, on top surface area la of the body 1 of the washing machine, there is a lid 2 for covering an opening for insertion and removal of the laundry, and at the same time, on a rear side of the lid 2, in other words, on a lower rear side of a control panel 17, there is a detergent intake device 19 for dissolving and discharging a detergent into the drum 3.
In the washing machine thus constructed, when it is used by opening the lid 2 formed on the top surface area 1a of the body 1 and tossing the laundry into the drum 3, the water is supplied into the drum 3 and at the same time, the dissolved detergent is thrown into the drum from the detergent intake device 19.
When a predetermined quantity of water and detergent is supplied into the drum 3, the driving means 11 starts to operate. At this moment, a turning effect of the driving means 11 is transferred to the decelerator 9 through the power transfer means 13 and pulleys 12 and 14 to thereby rotate the decelerator 9 in opposite directions, so that the washing is performed by way of the currents of water formed by the oscillation of the stirring blades 7 attached to a driving axis of the decelerator 9.
Meanwhile, after the washing is finished, in accordance with an operation of the drainage means 16 attached to the drainage pipe 15, the water is discharged to the outside of the body 1, and in sequence, a washing cycle comprising another intermediate spin-dry, rinse, spin-dry and the like is automatically executed to thereby perform the laundry washing.
However, in the washing machine thus constructed to perform the washing by way of the water currents, organic or inorganic materials attached to the laundry can be separated to some extent, but insoluble organic or inorganic materials such as dirt, fat and the like can hardly be separated from the laundry solely by water currents.
Therefore, these kinds of insoluble foreign objects are separated by the detergent, in other words, by an assistance of a surface active agent for changing respective surface tensions of the water, fabrics and the foreign objects, to thereby be washed out. However, the foreign objects stuck to underwears, socks and other white-colored fabrics can not be washed thoroughly with the detergent, so that such laundry is first boiled in a separate container.
However, because a boiled washing method thus described is performed after the laundry, the detergent and the water are poured into a separate container to which heat is applied by gas, electricity and the like, a special attention should be always paid to avoid a burning of the laundry or danger of fire.
