- the second washing tub is not dehydrated at this time, it is judged whether it is waited until the dehydration is completed and then drained. It can be avoided that the first washing tub has just drained water, and in the case where the second washing tub starts to dehydrate, the water of the first washing tub does not have the effect of damping, resulting in waste.
- the entire washing machine has only one drain port, and the two washing machines simultaneously drain water, and the washing water may return due to the pressure difference, thereby causing laundry pollution.
- a drain pipe is shared, and the speeds of the row and the row are substantially the same, so the first washing tub and the second washing tub cannot be drained at the same time.
- the first washing tub is about to drain, it is judged whether the second washing tub is draining at this time. If the second washing tub is draining at this time, the first washing tub waits for drainage after the second washing tub is drained, otherwise the water of the first washing tub is directly drained.
- the first washing tub In order to reuse the water in the first washing tub, when the first washing tub reaches the draining program, it is determined whether the water in the first washing tub can be reused. If not, the water in the first washing tub is directly drained, and if so, the judgment is made.

The second washing tub is filled with water, the water of the first washing tub is discharged into the second washing tub, and the water is reused. If T 12 ⁇ T 1 , it means that the water of the first washing tub is not directly discharged in the time range allowed to wait.
- the water of the first washing tub may be Reuse, otherwise the water in the first washing tub can not be reused, and the water is directly drained away.
- the first washing tub When the first washing tub reaches the draining program, it is determined whether the second washing tub is performing or is about to be the last rinsing water, and if so, the water of the first washing tub directly drains the water, and if not, continues to judge the first Whether the water in the washing tub can be reused.
- the first washing tub and the second washing tub are only for convenience of description, regardless of the order relationship, and when the second washing tub is drained, it is judged whether the first washing tub is dehydrating at this time, and if it is dehydrating, the second washing is performed.
- the cylinder waits for the first washing tub to be drained after the dewatering is completed; the water in the second washing tub acts as a counterweight, which can increase the weight of the washing machine and achieve the effect of damping.
- the first washing tub is not dehydrated at this time, it is judged whether it is waiting until the dehydration is completed and then drained. Can avoid the second When the washing tub has just drained water and the first washing tub starts to dehydrate, the water of the second washing tub does not have the effect of damping, resulting in waste.
- the first washing tub When the first washing tub reaches the draining program, it is judged whether the second washing tub is running at this time. If so, it is judged whether the second washing tub is or is about to perform the dehydrating process, and if not, the first washing tub directly executes the draining process.
- control method in this embodiment is:
- step 5) determining that the second washing tub is dehydrated for a time T 32 , determining that the second washing tub is used for dehydration for T 33 , setting an allowable waiting time T 3 , and if T 32 ⁇ T 3 -T 33 , performing step 6 ), otherwise go to step 8)
- the first washing tub waits for the second washing tub to be dehydrated, and proceeds to step 8)
- the first washing tub waits for the second washing tub to drain, and proceeds to step 8)
- the first washing tub 1 and the second washing tub 2 are connected to the same water inlet pipe via a pipeline, and the pipeline is provided with a control device for controlling water flow breakage. Thereby, the washing water can be injected into the first washing tub and/or the second washing tub through the inlet pipe phase before the washing process is performed.
- the inlet water flow rate of the household water inlet pipe is constant, when the first washing tub and the second washing tub simultaneously enter water, the inflow water flow rate is small, and the first washing tub and the second washing tub do not reach the setting.
- the occurrence of the water level condition; the flow rate of the influent water is unstable, and the problem of the water level of the washing water in the first washing tub and the second washing tub cannot be accurately determined.
- the water quantity or the water level in the cylinder is continuously or periodically monitored to prevent insufficient water in the cylinder and to sufficiently absorb water after the laundry.
- the resulting water level reduction problem is improved, and the washing water is replenished in time.
- the second washing tub cannot simultaneously perform any one of the water inflow and the water replenishing procedures; likewise, when the second washing tub performs the water inflow procedure, the first washing tub cannot simultaneously Perform any of the influent and hydration procedures. Thereby, the occurrence of simultaneous water inflow of the two cylinders is avoided.
- a water control control method for a multi-tubular washing machine is introduced as follows.
- the water inlet-hydration control method of the multi-roller washing machine is as follows:
- step 4 If yes, go to step 4); if no, go to step 3);
- step 4 If yes, go to step 4); if no, go to step 5):
- step 5 the first washing tub stops executing the water inlet program, and after the second washing tub water inlet or hydration procedure is completed, step 5) is performed;
- the first washing tub performs the water inlet process until the water inlet is completed
- the first washing tub performs a washing process
- step 8 if the water level of the washing water in the first washing tub is lower than the set water level
- the first washing tub performs a water filling procedure
- step 13 If yes, go to step 13); if no, go to step 10);
- step 11 If yes, go to step 11); if no, go to step 12):
- the first washing tub stops executing the water replenishing process, after the second washing tub hydration process is completed, step 12);
- the first washing tub performs a water filling process, and after the washing water in the first washing tub reaches the set water level, the water filling procedure is terminated;
- the second washing tub stops executing the water inlet program, and the first washing tub performs the water filling process. After the washing water in the first washing tub reaches the set water level, the second washing tub resumes performing the water inlet program.
- the set water level is a set value corresponding to the washing program executed by the first washing tub.
- the second washing tub cannot simultaneously perform the water inflow or hydration procedure.
- the water inlet program of the first washing tub is completed in such a condition that the level of the washing water in the first washing tub reaches the set water level.
- the first washing tub and the second washing tub have the same water supply control method; that is, the positions of the first washing tub and the second washing tub in steps 1) to 13) can be exchanged.
- the hydration control method of the second washing tub is performed.
- Special case 1 When the first washing tub is performing the water inflow procedure, if the second washing tub needs to perform the water filling procedure, the first washing tub waits, the second washing tub normally performs the water filling procedure; after the second washing tub is finished hydrating The first washing tub performs the water inflow procedure. Therefore, the washing tub with short washing time is prioritized, the waiting time of the user is reduced, and the degree of humanization of the whole machine is improved.
- the washing machine can only issue one water inflow command or water replenishment command at any time, and the command can only control one of the first washing tub and the second washing tub to perform a water inlet procedure or a water replenishing procedure. Therefore, the control unit of the washing machine can only issue an instruction to inject or replenish water to the first washing tub or the second washing tub at the same time, thereby preventing the first washing tub and the second washing tub from simultaneously performing the water inflow or the hydration procedure. occur.
- a sensor for detecting the water level of the washing water is provided in each of the first washing tub and the second washing tub.
- the inlet valve remains open until the sensor detects that the washing water reaches the set water level, the inlet valve closes, and the water inlet procedure is completed.
- the water filling program is started in the first washing tub or the second washing tub, the inlet valve is kept open, and the sensor detects washing. After the water reaches the set water level, the inlet valve closes and the water replenishment process is completed.
- whether the first washing tub and the second washing tub are performing the water inflow procedure or the water replenishing program is whether the corresponding inlet valves of the first washing tub and the second washing tub are open.
- the judgment method of whether the inlet valve is opened is that when the last command received by the inlet valve is an opening command, it is judged that the inlet valve is in an open state; when the last received command is a closing command, it is judged that the inlet valve is closed. .
