Washing machine and control method thereof

Abstract

The invention provides a washing machine and a control method thereof. The washing machine comprises a washing cylinder, a water inlet pipeline and a laundry detergent automatic feeding device. The water inlet pipeline is provided with an inlet valve used for conducting the water inlet pipeline, and the water inlet pipeline is configured in a way that during the water feeding period of the washing machine, the water inlet pipeline provides laundry water for the washing cylinder. The laundry detergent automatic feeding device is configured in a way that after the water inlet pipeline is conducted, the laundry detergent automatic feeding device is controlled to pour laundry detergent into the washing cylinder. According to the invention, a control method that the laundry water is poured into the washing cylinder first, then the laundry detergent is poured into the washing cylinder is employed, the laundry detergent does not deposit in a water discharge pipeline between a water outlet and a drainage pump of the washing cylinder, the failure rate of the drainage pump can be reduced, and the fact that the washing machine operates stably for a long time is guaranteed.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine and a control method thereof. Background technique [0002] At present, washing machines have been widely used in families. When the existing washing machines put laundry agents into the washing tub, they can be put in automatically by the washing machine or manually by the user. For a washing machine with an automatic laundry agent dosing device, it usually automatically injects laundry detergent into the dispenser box while water is being fed in, and the water in the dispenser box is provided by the water inlet line Laundry agents are carried into the washing tub. For a washing machine without an automatic injection device for laundry detergent, it is usually manually injected into the dispenser box by the user before the water enters, and the water in the dispenser box provided by the water inlet pipeline is used to fill the dispenser box. The laun...

Problems solved by technology

This will cause at least part of the laundry agent to flow into and deposit in the drainage pipeline between the drain outlet and the drain pump through the drain at the bottom of the washing tub, making it difficult for this part of the laundry agent to be fully dissolved and utilized. When draining, it is discharged with water, which reduces the utilization efficiency of laundry detergent, which not only causes waste of laundry detergent, but also aggravates the pollution to the environment
