DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an operation principle of a washing machine having a bladder according to an embodiment of the present invention will be described.

When the user starts the washing cycle after putting the detergent into the detergent case 22, the washing water is supplied into the detergent case 22 through the dispenser 21. As the water level in the detergent case 22 gradually increases due to the continuous supply of the washing water, the float 32 floats upward.

The stopper 31 closes the discharge port 22a until the water level in the detergent case 22 reaches a predetermined level so that the wash water is not discharged through the discharge port 22a but stored in the detergent case 22, Since the detergent is in constant contact with the detergent, the dissolution rate of the detergent is increased.

When the water level in the detergent case 22 reaches a predetermined level, the stopper 31 connected to the breech 32 by the connection portion 33 also floats upward due to the rise of the breech 32, Opening takes place.

The washing water in the detergent case 22 is supplied to the water supply bellows pipe 23 by the opening of the discharge port 22a and the detergent already dissolved by the washing water is also supplied to the water supply bellows pipe 23 together with the washing water.

When the water level in the detergent case 22 drops below the predetermined level as the washing water is discharged through the discharge port 22a, the force to float the stopper 31 upward is lost as the float 32 is also lowered. Thereby, the stopper 31 sinks downward again and is guided by the flow preventing portion 25 to correctly close the discharge port 22a.

Thereafter, the opening and closing of the discharge port 22a described above is repeatedly performed by supplying the washing water.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
