Description

[Detailed Description of the Invention] The present invention relates to a two-tub washing machine that can easily employ a dehydration and rinsing method.

Recently, in order to minimize the consumption of washing water, a spin-rinse method has been considered in which the laundry is transferred to a spin-drying basket before rinsing, and the process of spin-drying, pouring water, and spin-drying takes place, but this method is not currently in production. Since a two-tub washing machine is configured to supply water only to the washing tub, in order to perform water injection using the dehydration rinse method, the water supply hose must be removed from the water supply port provided in the operation box, for example, and therefore the dewatering capacity is reduced. The work of pouring water onto the laundry items that have been moved inside becomes extremely troublesome.

The present invention has been made in view of the above circumstances, and provides a water guiding member having a first outflow path for supplying water to the washing tub through a partition wall and a second outflow path for injecting water into the dewatering basket. A container-shaped water supply guide member, the lower end of which is inserted between the water guide member and a water supply port provided in the operation box, is provided to rotate along one plane, The outflow portion of the guide body is arranged to face the open upper surface of the water guide member with a predetermined distance therebetween, and the water supplied from the water supply port body is transferred to the first and second ports based on the rotation of the water supply guide body. By selectively supplying water to the washing tub or the dewatering basket through one of the outflow channels, it is possible to very easily supply water to the washing tub as well as pouring water into the dehydrating basket. To provide a two-tub type washing machine capable of saving washing water.
