Abstract: The present invention relates to a washing machine which comprises: a cabinet having a first insertion hole; a tub provided in the cabinet and having a second insertion hole aligned with the first insertion hole; a cabinet door provided to the cabinet, for opening and closing the first insertion hole; a tub door provided to the tub, for opening and closing the second insertion hole; a hinge unit for elastically supporting the tub door in the opening direction of the second insertion hole; and an antifriction member provided on one surface among the surfaces where the tub door and the cabinet door face each other, for preventing a direct friction between the tub door and the cabinet door. Accordingly, the present invention prevents the vibration and noise from the tub from being transmitted to the cabinet and may increase the capacity of the tub. In addition, when opened and closed, the cabinet door for opening and closing the cabinet and the tub door for opening and closing the tub operate in association with each other, thereby being capable of giving convenience to a user.

Abstract: A control method of a laundry treating apparatus includes rotating a drum at a reference rotational speed that is lower or higher than a resonance rotational speed of the laundry treating apparatus; measuring the maximum displacements of tub front and rear surfaces and a phase difference between the maximum displacements during the rotation of the drum at the reference rotational speed; determining a front unbalance (UB) mass located in a drum front area, a rear UB mass located in a drum rear area, and an angle between the UB masses based on the maximum displacements and the phase difference; and accelerating a drum rotational speed to a target rotational speed that is higher than the reference rotational speed and the resonance rotational speed, when the front and rear UB masses are in a preset allowable mass range and an angle between the UB masses is in an allowable angle range.
