Example eight

A washing machine drainage control method, the washing machine comprising a wire filtering device and a water purifying device, the wire filtering device comprising a casing 2 and a filter net 3 disposed in a cavity of the casing 2, the casing 2 being provided with a water inlet 1. The first water outlet 4 and the second water outlet 5, the water inlet 1 and the first water outlet 4 are connected, and a filter network 3 is formed between the two to form a filtered water path, and the water inlet 1 and the second water outlet 5 are directly connected. A flushing waterway for rinsing the filter 3 is formed between the two, the first water outlet 4 is connected to the water inlet of the water purifying device, and the water outlet of the water purifying device is connected to the washing tub. The control method includes the water circulation purifying step:

Controlling the first water outlet 4 to open, the second water outlet 5 is closed, the filtered water passage is connected, the flushing water passage is closed, the wire is trapped on the surface of the filter 3, and the water enters the water purifying device from the first water outlet 4 and the filter net 3, After the purification treatment, it is returned to the washing tub.

The control method includes a wire rinsing discharge step of controlling the first water outlet 4 to be closed, the second water outlet 5 to open, the filtered water passage to be closed, the flushing water passage to be opened, and the water flowing through the flushing water passage to be trapped on the surface of the filter 3 The chips are washed away and discharged from the second water outlet 5 to the outside of the washing machine.

Before the washing machine starts to drain, the turbidity of the drainage water is detected. If the detected turbidity is less than or equal to the set value, the first water outlet 4 is controlled to be opened, and the second water outlet 5 is closed, so that the filtered water passage is connected and the flushing water passage is closed; If the turbidity is greater than the set value, the first water outlet 4 is controlled to be closed, and the second water outlet 5 is opened, so that the filtered water passage is closed and the flushing water passage is opened.

Before the washing machine starts to drain, check the interception amount of the wire scraper. If the interception amount of the detected wire scrap is less than or equal to the set value, the first water outlet 4 is controlled to be opened, and the second water outlet 5 is closed, so that the filtered water passage is connected and the waterway is flushed. If the interception amount of the detected wire scrap is greater than the set value, the first water outlet 4 is controlled to be closed, and the second water outlet 5 is opened, so that the filtered water passage is closed and the flushing water passage is opened.

The water outlet of the water purifying device is provided with a water quality detecting device. If the water quality detecting value at the water outlet reaches a preset standard, the water outlet of the water purifying device is controlled to open, so that the water enters the washing tub from the water outlet; if the water quality at the water outlet If the detected value does not reach the preset standard, the outlet of the water purifying device is controlled to be closed, and the water is continuously circulated and purified in the water purifying device until the preset standard is reached.

The water purifying device detects the water level in the washing tub when the purified water is circulated to the washing tub, and controls the washing machine to perform hydration if the detected water level is lower than the preset water level.

The present invention provides a washing machine provided with the above-described washing machine drain control method.

The drainage control method realizes repeated recycling of washing water, improves water resource utilization, saves water, and is environmentally friendly;

The drainage control method has simple steps and ingenious design. By cooperating with the washing machine device, the water recycling is realized, and the wire scraps are effectively removed to prevent the wire debris from remaining on the clothes. In particular, the collected cuttings can be thoroughly washed out during the drainage process, and the waste water is used to clean the wire, thereby achieving self-cleaning of the wire, making full use of material resources and energy, convenient and fast, and meeting the user's needs;

The drainage control method is selectively utilized in the water recycling process according to the specific conditions of the water, and comprehensively considers the cost of recycling and water purification treatment, and strives to reduce the overall cost of the washing machine operation.

Example nine

A washing machine drainage control method, the washing machine drainage control method, comprising the following steps:

Step S1, turning on the power, selecting a program;

Step S2, opening the main washing valve, and washing the washing powder to the standard water level;

Step S3, entering the main washing and drying stage;

Step S4, entering the rinsing stage, controlling the first water outlet 4 to open, the second water outlet 5 to be closed, so that the filtered water passage is connected, the flushing water passage is closed, the swarf is trapped on the surface of the filter net 3, and the water is filtered by the first water outlet 4 The net 3 enters the water purifying device, and is returned to the washing tub after the purification treatment, and is executed cyclically;

Step S5, entering the drainage stage after rinsing, controlling the first water outlet 4 to be closed, the second water outlet 5 is opened, the filtered water passage is closed, the flushing water passage is opened, and the water flowing through the flushing water passage will be trapped on the surface of the filter 3 Walk and drain from the second outlet 5 to the outside of the washing machine;

In step S6, the drying process is completed and the washing is completed.

In the step S4, the turbidity of the water is detected. If it is greater than the set value, the cycle execution is stopped, the first water outlet 4 is closed, and the second water outlet 5 is opened, so that the filtered water passage is closed and the flushing water passage is opened.
