The present invention relates to a washing machine, and more particularly, to a top-load type washing machine in which laundry is loaded from top to bottom.

In general, a washing machine may be divided into a drum type in which an inner tub, which is a washing tub, rotates about a horizontal direction with respect to the ground, and a top rod type in which the inner tub rotates about a vertical direction with respect to the ground. In the drum method, the laundry is washed while the inner tub is rotated and the laundry rubs against the inner wall surface of the inner tub or falls, whereas in the top-load method, the pulsator provided on the bottom surface of the inner tub rotates to generate a water flow, and the water flow and The laundry is rubbed or the pulsator applies an impact to the laundry so that it is washed.

The top-loaded washing machine includes an outer tub that is a water storage tub, and an inner tub that is rotatably disposed in the outer tub and accommodates laundry. A plurality of through-holes are formed in the circumferential surface of the inner tub through which wash water contained in the outer tub can pass in and out of the inner tub.

In addition, a motor for rotating the inner tank is installed below the inner tank, so that the inner tank may be rotated by a driving force of the motor.

On the other hand, the water level of the wash water contained in the outer tub rises by the rotational force of the inner tub, and the raised water flow may overflow to the outside of the outer tub through the space between the outer tub and the inner tub.

In order to prevent the elevated water flow from overflowing to the outside of the outer tank, an outer tank cover is provided on the upper portion of the outer tank. The outer tank cover serves to guide the water flow raised through the space between the outer tank and the inner tank to the upper side of the inner tank, so that the raised water flow is introduced into the inner tank.
