The present disclosure relates to a washing machine, and more particularly, to an integral type washing machine capable of continuously performing washing, rinsing and dewatering with a single apparatus.
In general, various laundries are generated in daily life. Such laundries are required to be periodically washed for a clean and hygienic life.
At ordinary homes, bedding such as quilt or blanket, and large laundries such as carpet, sofa cloth, curtain or the like are generated. These laundries are hard to be washed at the home. Thus, the washing of the laundries is typically performed by a washing plant of a special treatment establishment.
In addition, laundries generated in a multi-use facility such as a hotel, a factory, a boarding house, a training center, a hospital or the like are very large. In addition, such laundries have a relatively large size and thus, are mainly treated in a specialized treatment establishment and a washing plant.
On the other hand, the washing plant typically uses a drum-type washing machine to wash the laundry. In the case of using the drum-type of washing machine, water discharged every time when processes such as a main washing, a primary rinsing, a secondary rinsing and a dewatering are performed is discarded in-situ. Thus, very large volumes of water may be consumed. In addition, from the viewpoint of economic compensation, underground water may be irrationally dug and used. This may cause a problem in that wastage of water resources and discharge of polluted water have an adverse effect on the environment.
