In the process of executing step S2, it is preferable to make the digital display tube of the laundry device display the residual water draining code, for example, display "Ud" or other residual water draining prompting code on the digital display tube, and at this time, the laundry device is completely in the standing state, i.e., the power-on standby state, which is beneficial to avoid that the user mistakenly thinks that the residual water draining procedure is finished and the laundry device is powered off and shut down in advance, so as to ensure that the subsequent steps of the residual water draining procedure can be executed continuously.
S3: starting the drainage assembly for a third preset time;
the step S3 is to discharge the residual water at the bottom of the barrel, where the residual water at the bottom of the barrel at least includes the residual water in the previous water inlet pipe 5, external water suction pump 4 and water suction pipe 3 and the residual water in the inner wall of the outer barrel 1 and the inner and outer walls of the inner barrel 2, the time for opening the water discharge assembly ensures that the residual water at the bottom of the barrel can be fully discharged for a third preset time, which can be obtained by experiments, for example, the third preset time can be set to 1min, and such adjustment and change of the third preset time do not limit the present invention. In this step, the drain valve 8 of the drain assembly may be opened for a third preset time.
S4: the laundry device performs the single spin-off process to rotate the inner tub 2 for a fourth preset time.
The step S4 is to rotate the inner tub 2 by making the laundry device perform a single-spin procedure, that is, the inner tub 2 rotates relative to the outer tub 1, and an air flow is generated during the rotation of the inner tub 2, so as to dry the inner and outer walls of the inner tub 2 and the inner wall of the outer tub 1, and to ensure that the time for performing the single-spin procedure of the laundry device lasts for a fourth preset time, which can be obtained by experiment, for example, the fourth preset time can be set to 15min, and such adjustment and change of the fourth preset time do not limit the present invention. In this step, if the drain assembly has a drain motor, the drain motor is also turned on, and it is ensured that the drain valve 8 is continuously opened, if there is residual water in the drying process, the residual water is further discharged out of the outer tub 1, and the residual water in the drain pipe 7 can be continuously discharged.
After the step S4, the inner tub 2 of the laundry device may be in an inertia deceleration state (i.e., the dewatering motor is powered off), and when the rotation speed of the inner tub 2 reaches a low rotation speed, a command to close the drain valve 8 and the drain motor is sent, and the inner tub 2 is powered off after braking, specifically, the control may be performed by detecting a change in the rotation speed of the inner tub 2 or by time, for example, the drain valve 8 and the drain motor are closed after the dewatering motor is powered off for 55 seconds, and the inner tub 2 is powered off after braking.
Preferably, in case that the laundry device ends the washing course, the drain residual water control method of the present invention further comprises: and sending out a washing end prompt. The advantage of setting up like this lies in that the user can close tap, avoids follow-up water intaking valve 6 to open the back water pipe 5 and continues to fill water to interior bucket 2 to the user also can take out external suction pump 4 from external water tank according to the suggestion, avoids external suction pump 4 to open the back water pipe 3 and continues to fill water to interior bucket 2. In the invention, the manner of sending the washing end prompt can be a buzzing prompt, namely, the buzzer of the washing equipment sends an alarm prompt, for example, the sound prompt can be sent at intervals by '0.1 on-0.05off-0.1on-0.05 off', namely, the prompt sound is alternately sent in a manner of turning on 0.1s and turning off 0.05s, the prompt time can last for 1min, and the user is informed of the treatment.
In practical applications, the washing apparatus may automatically perform the residual water draining process after the prompt, and it is preferable that the user may select whether to perform the residual water draining process. In one possible case, a residual water draining function key is provided on a control panel of the laundry device, and a residual water draining command of the laundry device is input to the laundry device when the residual water draining function key is selected, that is, a user may cause the laundry device to perform a residual water draining process by selecting the residual water draining function key. In another possible case, the control panel of the laundry device is not provided with a residual water draining function key, and a residual water draining command of the laundry device is input to the laundry device when the original function key is selected and lasts for a fifth preset time, for example, the residual water draining function can be selected by selecting the "program" function key for more than 5s, and hearing the prompt tone of "drip" represents selecting the function. Alternatively, there may be no residual water draining function key on the control panel of the laundry device, and a residual water draining command of the laundry device is input to the laundry device when at least two original function keys are simultaneously selected or when at least two original function keys are simultaneously selected and last for a fifth preset time, for example, the residual water draining function is selected by pressing the "program" function key and the "water amount" function key 3s for a long time, and the function is selected when the "dripping" prompt sound is heard. Of course, for the laundry device with the internet of things function, for example, the controller of the laundry device is connected to the smart terminal (e.g., a mobile phone, a tablet, a smart watch, or a bracelet), and the instruction for draining the residual water of the laundry device is input to the laundry device through the smart terminal.
