Problems solved by technology

[0006] The above-mentioned patent uses a spherical valve plug to enhance the sealing performance and prevent water leakage by changing the structure. Sundries such as coins, paper clips, etc., even if a spherical valve is used, the seal between the valve plug and the closed ring cannot be sealed due to the existence of hard sundries, and the design of the spherical surface will therefore fail

Embodiment 1

[0088] like figure 1 As shown, a control method for preventing the drain valve of the washing machine from leaking in this embodiment includes:

[0089] Step 1) start the washing machine;

[0090] Step 2) The washing machine executes the water leakage control program of the anti-drain valve;

[0091] Step 3) Control the drain valve to open and close;

[0092] Step 4) The washing machine judges whether the number of opening and closing actions of the drain valve reaches X times;

[0093] Step 5) If the judging result is no, return to step 3), if the judging result is yes, the washing machine starts to enter water, and executes the subsequent process.

[0094] The subsequent process in step 5) of this embodiment may be a washing process, a rinsing process or a dehydration process, which is selected by the user.

[0095] In this embodiment, the anti-drainage valve leakage control program is executed before the washing machine starts for the first time to ensure that the drain...

Embodiment 2

[0097] like figure 2 As shown, a control method for preventing water leakage from the drain valve of the washing machine in this embodiment includes:

[0098] Step 1) start the washing machine;

[0099] Step 2) The washing machine executes the washing process;

[0100] Step 3) The washing machine judges whether the washing process is over;

[0101] Step 4) If the judgment result is yes, then go to step 5), if the judgment result is no, then return to step 2)

[0102] Step 5) Control the drain valve to open to discharge the washing water;

[0103] Step 6) Laundry judges whether the washing water is drained;

[0104] Step 7) If the judgment result is yes, then enter step 8), if the judgment result is no, then return to step 5);

[0105] Step 8) control the drain valve to close;

[0106] Step 9) The washing machine executes the water leakage control program of the anti-drain valve;

[0107] Step 10) controlling the drain valve to open and close;

[0108] Step 11) The was...

Embodiment 3

[0113] like image 3 As shown, a control method for preventing the drain valve of the washing machine from leaking in this embodiment includes:

[0114] Step 1) start the washing machine;

[0115] Step 2) The washing machine performs a dehydration or drainage process;

[0116] Step 3) control the drain valve to open;

[0117] Step 4) The washing machine judges whether the dehydration or drainage process is over;

[0118] Step 5) If the judgment result is yes, then enter step 6), if the judgment result is no, then enter step 3);

[0119] Step 6) control the drain valve to close;

[0120] Step 7) The washing machine executes the anti-drainage valve leakage control program;

[0121] Step 8) Control the drain valve to open and close;

[0122] Step 9) The washing machine judges whether the number of opening and closing actions of the drain valve reaches X times;

[0123] Step 10) If the judgment result is no, return to step 8), if the judgment result is yes, enter the rinsin...

Abstract

The invention provides a control method for preventing a washing machine drain valve from leaking water. A washing machine executes a drain valve water leakage control program before water inflow or after drainage. The drain valve water leakage control program comprises the step of controlling the drain valve to execute switching-on and switching-off motions again after the drain valve is shut down. The invention also provides a washing machine adopting the control method. According to the control method for preventing the washing machine drain valve from leaking water, no matter whether there are impurities between a valve plug and a valve body, it can be guaranteed that the valve plug and the valve body can be sealed completely after the drain valve is switched off again. Therefore, according to the control method for preventing the washing machine drain valve from leaking water, control logic of priority judgment is adopted, and the control method is easy to implement and easy to control.

Description

technical field [0001] The invention relates to the technical field of treatment for preventing water leakage from a drain valve of a washing machine, in particular to a control method for preventing water leakage from a drain valve of a washing machine and a washing machine thereof. Background technique [0002] With the improvement of people's quality of life, the frequency of use of washing machines is getting higher and higher, and people's requirements for washing machines are also getting higher and higher. Therefore, whether the washing machine can be used normally for a long time and avoid the shutdown of the washing machine caused by a fault report for repair has attracted more and more attention and attention. [0003] Existing washing machines mostly adopt the drainage mode of lower drainage. During the washing process of laundry, some laundry lint will inevitably be produced, and small items such as coins, toothpicks, and paper clips that have not been taken out...
