Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-tub washing machine having a function of forcibly capturing lint by the pumping action of stirring blades.

2. Description of the Related Art Conventionally, there is a two-tub washing machine in which lint is forcibly captured by sending water to a lint catcher provided at the upper part of the washing tank by a pumping action of an agitating blade. However, with something like this,
When the water level is set to high, the water surface is high, so the head when viewed from the pump function is small, and on the other hand, when the water level is set to low, the head is large. Therefore, if the pump capacity is designed to match a high water level, the amount of water discharged will be significantly reduced during low water level operation, resulting in a decrease in lint capture efficiency. On the other hand, if the pump capacity is designed to match the low water level, the amount of water discharged will be too large during high water level operation, and the water will overflow from the lint catcher together with the lint.

The present invention was made in view of the above-mentioned circumstances, and its purpose is to adjust the height of the lint trap according to the height of the water level, so as to optimize the amount of water fed to the lint trap.
