Abstract: A washing machine with a balancer to counterbalance unbalanced load produced during rotation of a drum and a control method thereof. The washing machine with a balancer to counterbalance unbalanced load produced during rotation of a drum perform a ball distributing cycle of seating masses in a groove in the balancer before rotation of the drum possibly producing unbalance as in the spin-drying cycle begins to efficiently maintain balance of the drum, and a laundry untangling cycle of evenly distributing the laundry in the drum. Accordingly, vibration and noise may be reduced during the spin-drying cycle. In addition, in retrying the spin-drying, the ball distributing cycle is restricted based on the rate of rotation of the motor at the moment at which unbalance is sensed. Thereby, delay in cycle time in retrying the spin-drying cycle may be prevented.

Abstract: Disclosed herein is a dishwasher including a spray unit fixed to one sidewall of a wash tub and a reflecting plate assembly to reflect wash water sprayed from the spray unit onto dishes and to linearly reciprocate in a spray direction of the wash water sprayed from the spray unit. The dishwasher further includes a drive unit to drive the reflecting plate assembly, and a cam unit to transmit driving force of the drive unit to the reflecting plate assembly. The drive unit includes a motor to generate rotational force, and a belt forming a closed loop and caused to make cyclic movement by the motor. The cam unit is engaged with the belt to transmit power of the belt to the reflecting plate assembly. The cam is alternately engaged with first and second portions of the belt to cause the reflecting plate assembly to reciprocate.

Abstract: A refrigerator includes a mid-frame positioned on a front surface of the main body wall and a heater configured to heat the mid-frame and provided at the mid-frame. The mid-frame includes a front frame provided to cover at least a part of a front surface of the at least one inner box configured to form the main body wall, and an extension frame formed to extend rearward from the front frame and including an edge portion in which an end portion of the extension frame has a thickness greater than that of an adjacent extension frame.
