A water reuse control method of a multiple-drum washing machine, having a first washing drum and a second washing drum. When the first drum reaches a drainage process, comparing a time for the second drum to reach a water supply process T.sub.12 to a time for the first drum to reach a next drainage process T.sub.11; if T.sub.12<T.sub.11, the first drum waits until water is supplied into the second drum; if T.sub.12≧T.sub.11, water in the first drum is directly drained. Alternatively, when the first drum reaches the water supply process, comparing time for the second drum to reach the drainage process T.sub.22 to time for the first drum to reach a next water supply process T.sub.21; if T.sub.22≧T.sub.21, clean water is directly supplied into the first drum; if T.sub.22<T.sub.21, the first drum waits until the second drum drains water.

A washing machine having a reminding function for preventing clothing from fading, comprising: an outer drum for accommodating washing water; a color sensor arranged on the washing machine and detecting the color of the washing water, so that according to changes in the color of the washing water in a washing process, it is determined whether the clothing being washed is fading or not. Detection of the color of the washing water achieves the aim of determining, according to the changes in the color of the washing water, whether the clothing being washed is fading or not, thereby improving the sensitivity and accuracy of determination, and preventing a situation wherein fading clothing contaminates the washing water then causes secondary contamination of other clothing being washed.

The souring of wet laundry in a laundry treating appliance may be retarded by sending an alert signal indicative of an ending of a cycle of operation from the laundry treating appliance to a remote electronic device. The appliance may receive an authorization signal from the electronic device indicative of an instruction to execute an anti-sour cycle. An anti-sour cycle comprising the energizing of a fan to flow air through a laundry treating chamber may be automatically initiated for the laundry treating appliance.

A method of controlling a washing machine that includes a drum rotatably provided in a tub that receives water, at least one nozzle spraying water into the drum, a washing motor rotating the drum, and a circulation pump circulating water within the washing machine, the method including: operating the washing motor to rotate the drum in a first rotational direction while repeatedly alternating between an acceleration and a deceleration of the drum so that laundry in the drum alternates between maintaining contact with an inner surface of the drum during acceleration, and separates from the inner surface of the drum during deceleration; and operating a circulation pump motor in the circulation pump, while the drum rotates in the first rotational direction, to accelerate a pump speed of the circulation pump during the acceleration of the drum, and to decelerate the pump speed during deceleration of the drum.

Disclosed herein is a drum type washing machine capable of obtaining a high-water saving effect. The drum type washing machine comprises at least one processor configured to control a drive device configured to rotate a drum, a water supplier configured to supply water to a tub, and a sprinkler configured to spray water stored in the tub toward laundry accommodated in the drum. The drum comprises a lifter and a plurality of rear through-holes. The at least one processor is configured to perform a water spray process while rotating the drum in a state in which an amount of wash water absorbable by the laundry is maintained in the tub, in a washing cycle. In the water spray process, a waiting process, in which driving a circulation pump 91 is stopped, is intermittently and repeatedly performed.

A laundry treating apparatus includes a cabinet, a water tub provided inside the cabinet, and a detergent box to supply detergent to the water tub. The detergent box includes a housing connected to communicate with the water tub, a drawer having a plurality of detergent storage spaces and received in the housing to be drawn out, and a distribution unit to distributively supply wash water into the plurality of detergent storage spaces. The housing may include a through portion communicating with the water tub, a horizontal partition protruding above the through portion and disposed in a left and right direction, and a wash water guide unit to guide the wash water so that a plurality of wash water movement paths is defined at a front region of the horizontal partition. Accordingly, detergent residue at an inner front region of the housing can be suppressed.

The invention relates to a program-controlled apparatus (1) for washing items that is equipped with a water purification system (8) for purifying the wash liquor by removing detergent and suspended soil, which purification system (8) utilizes addition of flocculant, wherein the amount of flocculant that is added is controlled to minimize the total amount of flocculant used without compromising the efficacy of the purification treatment.

A method of controlling a washing machine includes the steps of: (a) processing the laundry by using the water supplied together with detergent; (b) draining the water used in the step (a), rotating the inner tub at a high speed, and operating the pump to drain the water discharged from the laundry; (c) rotating the inner tub at a first speed and supplying the water into the inner tub via the dispenser; (d) stopping the supply of water through the dispenser, rotating the inner tub at a second speed, and supplying the water into the inner tub through the spray nozzle; (e) stopping the supply of water through the spray nozzle and alternately rotating the pulsator at a third speed in both directions; (f) stopping rotation of the pulsator, rotating the inner tub at the second speed for a preset time, and supplying the water into the inner tub through the spray nozzle; (g) decelerating the inner tub from the second speed to a fourth speed, and operating the pump while the inner tub rotates at the fourth speed to drain the outer tub; and (h) accelerating and rotating the inner tub from the fourth speed to dewater the laundry.

A washing machine has a rotatable drum in a drum-receiving container with an outlet, a pump with integrated heating device, an injector on the drum-receiving container, a water circuit with several water pipes, wherein at least one water pipe runs from the outlet from the drum-receiving container to the pump, and at least one water pipe runs from the pump to the injector, and a water reservoir between the outlet and pump which is connected to the water pipe from the outlet to the pump. An outlet valve is provided in the water pipe from the outlet from the drum-receiving container to the pump. A pump valve is also provided which is connected to a water pipe with a pump outlet and has an output to a water outlet from the washing machine.

A method of controlling a washing machine that includes a tub, a drum rotatably disposed in the tub, at least one nozzle spraying water toward the drum, a washing motor rotating the drum, and a circulation pump circulating water discharged from the tub, the method including: supplying a first level of water into the tub; operating the circulation pump at a first speed; controlling a rotation of the drum to repeatedly alternate between an acceleration and a deceleration so that laundry in the drum alternates between maintaining contact with an inner surface of the drum and separating from the inner surface of the drum; further supplying water to the tub to raise the first water level to a second water level.
