Abstract: A laundry machine includes first and second washing units including first and second tubs, respectively. First and second drums are mounted inside the first and second tubs, and first and second drive units drive rotations of the first and second drums around first and second rotational shafts, respectively. The second washing unit is arranged above the first washing unit and has a smaller laundry treating capacity than the first washing unit. The first rotational shaft is not parallel to the second rotational shaft. A first recess projects downward from a rear lower surface of the second tub and is configured to heat wash water in the second tub. A metal plate member is provided on an outside lower surface of the second tub, and partially extends to the rear of the second tub to expose a bottom surface of the first recess.

Abstract: The present disclosure relates to a twin laundry machine, more particularly, to a twin laundry machine configured to control mutual motor operations of one or more laundry machines provided therein not to be overlapped with each other, in case the one or more laundry machines are put into operation to perform washing. The present disclosure also relates to a twin laundry machine of which a motor for driving a drum has an improved heat radiation function, more particularly, to a twin laundry machine which includes a sub-washing machine with a smaller size than a normal washing machine and frequent exposure to high temperature usage environments.
