FIG. 3 shows a state in which the lint filter 120 shown in FIGS. 1 and 2 is mounted on the outer cover 114.

Referring to FIG. 1, the laundry processing apparatus 100 includes a cabinet 111 having an upper opening and an upper opening, a cabinet cover 112 (see FIG. 1) provided at an opened upper portion of the cabinet 111, A door 113 which opens and closes the swinging and entering port, an outer tub 122 which is suspended in the cabinet 111 by a support member 117 and is buffered by a damper 118, And an inner tub 115 which rotates about a vertical axis and receives the can. A plurality of water holes (not shown) are formed in the inner tank 115 so that the washing water can circulate between the outer tank 122 and the inner tank 115. In the upper portion of the outer tank 122, (h) is formed on the inner surface of the outer cover.

Referring to FIG. 3, a lint filter 120 is detachably mounted on the outer cover 114. The lint filter 120 is made of a mesh or the like and is attached to the septum 115 and the seawater 122 contained in the circulating water stream (refer to FIG. 2) rising along the space between the inner tank 115 and the outer tank 122, And so on.

A pulsator 116 for generating a rotating water flow is provided at the bottom of the inner tank 115 and a motor 116 for generating a rotating force for rotating the inner tank 115 and / or the pulsator 116 is provided below the outer tank 122 130 are disposed. The inner tub 115 and the pulsator 116 are coupled together to the rotating shaft 132 and selectively rotated by a power switching means such as a clutch (not shown). A drain hose 142 and a drain pump 144 are provided to drain the washing water from the outer tub 122.

The cabinet cover 112 is provided with a control panel 124 for receiving commands from the user for the overall operation of the laundry processing apparatus 100. The cabinet cover 112 is provided with a detergent A detergent box housing 134 which houses the detergent box 134 in a detachable manner and forms a flow path so that the wash water introduced from the water supply hose 119 is supplied into the inner tank 115 via the detergent box 134 136 are disposed. A dispensing hole 136h may be formed in the detergent box housing 136 to distribute the wash water introduced from the water supply hose 118 to the detergent box 134.

1, the pulsator 116 rotates alternately in both directions to rotate the stirring water, which is formed by stirring the washing water, in a direction opposite to the rotating direction of the pulsator 116 and / or the inner tub 115, Respectively.

Hereinafter, the term " stirred water flow " is defined as a flow of washing water formed by rotating the inner tank 115 and the outer tub 122 in both directions, not rotating in one direction.

The stirring water may be circulated alternately in both directions by alternately rotating the pulsator 116 or rotating the inner tub 115 alternately in both directions or by simultaneously rotating the inner tub 115 and the pulsator 116 in different directions simultaneously And the like.

2, the washing water is concentrated to the edge by the centrifugal force generated when the inner tub 115 rotates, so that the water level of the washing water between the inner tub 115 and the outer tub 122 rises, The circulating water is circulated through the lint filter 120 provided in the washing tub 120 and then introduced into the inner tub 115. Hereinafter, it is defined as circulating water.

It is necessary to generate sufficient centrifugal force so that the washing water between the inner tub 115 and the outer tub 122 can rise toward the outer tub cover 114. To this end, the inner tub 115 is continuously rotated in one direction .

On the other hand, the rotational speed of the inner tank 115 for generating the circulating water needs to be set differently according to the water level of the washing water. This is because, as the water level of the washing water becomes lower, the inner tank 115 must be rotated at a higher speed to generate sufficient centrifugal force.

Referring to FIG. 4, when washing is started after power is applied to the laundry processing apparatus 100 by a user and setting conditions such as the type of laundry are input, the washing water is supplied to the inner tub 115 and the outer tub 122 (S10). Thereafter, a collecting step (S20) is carried out to stir the washing water immersed in the inner tank (115) and the outer tank (122) to form stirring water. By the stirring water flow formed in the unwinding step S20, foreign matter such as seams on the laundry is effectively separated.

Thereafter, the washing water is raised between the outer tub 122 and the inner tub 115 by centrifugal force to form a circulating water stream which is re-supplied into the inner tub 115 through the lint filter 120 provided in the outer tub cover 114 The filtering step S20 is performed. In the filtering step S20, foreign substances such as seams contained in the circulating water flow are filtered by the lint filter 120. [ By circulating the circulating water continuously between the inner tank 115 and the outer tank 120 and filtering the foreign matter such as the seams contained in the washing water effectively, it is possible to clean not only the laundry but also foreign materials such as seams, The drain hose 142 is blocked, and the drain pump 144 is prevented from being broken.

On the other hand, by repeating the unwinding step (S20) and the filtering step (S30) by the set number of times (S40), foreign matter such as seams stuck to the laundry is separated and collection of the foreign matter by the lint filter So that the filtering efficiency is improved.

For example, when only the filtering step S30 is performed, the laundry adheres to the side surface of the inner tank 115 due to the centrifugal force, so that the laundry is bundled and foreign substances such as seams are not easily separated from the laundry. In contrast, in the present embodiment, the stirring water is formed in the impregnating step S20 to separate the foreign matter from the laundry, and the foreign matter is filtered while the circulating water including the separated foreign matter passes through the lint filter 120 , The removal of the foreign substances contained in the washing water is performed very efficiently.

On the other hand, in consideration of the time required for the circulation channel to complete one cycle, it is preferable that the filtering step S0 is continued for a longer time than the forging step S20.
