The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A drum washing machine includes a casing 1 for accommodating an outer tub 2; an outer tub 2 for holding washing water; an inner tub 3 for accommodating laundry; and a controller 4 for controlling the laundry washing course and performing a yellowing prevention program.

The washing machine further comprises a color sensor 5, after the laundry is put into the inner tub 3, the color sensor 5 emits light to the laundry, judges whether light-colored laundry, especially white laundry, is contained according to the reflected light, and if yes, executes the yellowing prevention program. The program may also be selected by the user through a "yellow prevention" button on the washing machine.

The yellowing prevention program is performed as follows: firstly, a blowing program is executed, the inner drum 3 rotates at a speed higher than the washing speed to drive the clothes to tumble violently, so that dirt on the clothes falls off from the clothes, air is supplied into the inner drum 3 at a high wind speed, the fallen dirt is blown away from the clothes, the dirt can be collected into a filter, and the air is conveyed circularly; or the air can be directly discharged out of the outer barrel without arranging a filter.

And then, executing a spray washing program to spray and wash the clothes, rotating the inner barrel while washing, draining water, and washing away the dirt which is not taken away by the air through washing the clothes by the washing water. The time of the spraying washing program is set as 1-2 minutes of continuous spraying after the clothes are soaked, and the requirements of washing and water saving are met.

After the spraying washing is finished, executing a clothes soaking washing program, soaking most clothes in water by water inflow which is larger than normal washing water inflow, adding a detergent into a water inflow box by a detergent automatic adding device, flowing into the inner drum 3 along with the inflow, and rotating the inner drum to dissolve residual dirt of the clothes into the water; the washing is stopped, and the washing water is partially drained after standing for a while, and the amount of drainage of the washing water is determined based on the measurement value of the turbidity sensor 6. When the dirt degree is high, the discharged water amount is large, and the residual water amount in the outer barrel is small; when the dirt degree is low, the discharged water amount is small, and the residual water amount in the outer barrel is large.

After the soaking washing program is executed, the water replenishing washing program is started, the washing machine replenishes water to a normal washing water level, the controller 4 controls the automatic detergent adding device to replenish detergent according to the re-inflow amount, and the replenished detergent amount is less than the normal detergent amount matched with the inflow amount because most of dirt in the washing machine is discharged. The detergent may be replenished based on the measurement of the turbidity sensor. When the dirt degree is high, a detergent is supplemented; when the degree of contamination is low, the detergent is less replenished.

Therefore, most dirt is discharged before and during the washing stage, so that the dirt is prevented from remaining in the fiber of the clothes and causing coloring influence on light-colored clothes.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
