In a second washing stage of a fourth washing mode, controlling the water inlet valve assembly to feed water into the first detergent cavity and the second detergent cavity, controlling the first cold water valve to be opened, and simultaneously controlling the hot water valve to be closed to feed water into the first detergent cavity, so that the first detergent cavity is flushed, and detergent residue is avoided; and simultaneously controlling the second cold water valve to be opened so as to feed water into the second detergent cavity, and controlling the first cold water valve to be closed and the second cold water valve to be closed when the water level of the clothes treatment cavity reaches a second preset target water level, so that the water feeding into the first detergent cavity and the second detergent cavity is stopped.

That is, in the fourth washing mode, before water is fed, the hot water valve is in a normally closed state, the first cold water valve is in a normally open state, and water entering the first detergent cavity is cold water, so that the washing requirements of clothes made of special materials are met, or the washing agent is applied to clothes with less stains, and the washing energy consumption is reduced; the second detergent chamber is opened at the second washing stage to achieve the divided input of the detergent while replenishing the water in the laundry treating chamber to a target water level required for washing.

According to one embodiment of the present invention, the washing modes of the laundry treating apparatus have the above four kinds, and washing at different temperatures is achieved by controlling the opening and closing of the first cold water valve, the second cold water valve, and the hot water valve. In addition, the above target water levels are set according to different washing modes, and the water inlet time parameters of the cold water valve and the hot water valve are set according to different water levels and different water temperatures. And under the washing mode, the third cold water valve is controlled to be closed all the time, so that the softener is prevented from entering the clothes treatment cavity in the washing process to influence the using effect of the softener.

In addition, when the processing device is other washing devices such as a dishwasher, the washing control method may also have the above four washing modes, and the washing control method is the same as the above embodiments, and is not described herein again.
