s1: the washing machine enters water and starts a pre-washing mode;
s2: pre-washing is carried out, and an accumulated parameter D in the current pre-washing mode running state is obtained;
s3: judging whether water is required to be supplemented in the pre-washing process, if so, resetting the accumulated parameter D, and executing the step S2 after controlling the washing machine to supplement water;
s4: and judging whether the accumulative parameter D reaches a preset condition, and finishing water inflow when the accumulative parameter D reaches the preset condition.
The embodiment provides a method for automatically controlling water inlet time of a washing machine, wherein the sequence numbering of the steps is only used for conveniently expressing an automatic water inlet control program of the washing machine, time cross possibly exists among a plurality of steps in the actual control process, and the method also belongs to the technical scheme to be protected by the embodiment when the time cross occurs in the steps; specifically, a pre-washing mode is started through water inlet of the washing machine; acquiring an accumulated parameter D in a prewashing mode running state; judging whether water is required to be supplemented, further judging whether the accumulated parameter D reaches a preset condition when water is not required to be supplemented, and finishing water inlet when the accumulated parameter D reaches the preset condition; and when the accumulative parameter D does not reach the preset condition, maintaining the prewashing mode until the preset condition is reached. When water is needed to be supplemented, resetting the accumulated parameter D and controlling the water inlet of the washing machine; through the scheme, the mode of automatically controlling the water inlet time of the washing machine through common control of the water inlet amount and the pre-washing accumulated parameters is realized, and the problems that the water inlet time is long and cannot be reasonably controlled due to water supplement in a fixed time in the prior art are solved.
Preferably, in the step S1, the pre-washing mode is to perform at least one pre-washing operation on the washing machine, and multiple pre-washing operations are adopted in this embodiment; in step S2, accumulating the parameter D as the pre-washing times; the preset condition in step S4 is a preset pre-washing number value, and specifically, the pre-washing number is determined according to the washing instruction of the user and/or the data information of the laundry to be washed. In the specific implementation process, because of the influence of the material and/or the weight and/or the volume of the clothes to be washed, different clothes to be washed need different lengths of time for absorbing water, and different pre-washing times are set according to different materials and weights of the clothes to be washed, so that the embodiment provides a scheme as follows:
through treating the different settings of washing clothing prewashing number of times to can not appear when the washing process begins the back, because what the process of absorbing water of treating the washing clothing leads to does not reach the best washing water yield of the clothing of treating, solved among the prior art through set for the mode of fixed moisturizing time because of moisturizing time is not enough to lead to intaking not enough, influence the technical problem of washing effect. The above embodiment merely illustrates that the preset condition is determined according to the data information of the laundry to be washed when the preset condition is the preset pre-washing times; in the specific implementation process, the preset condition of the accumulation parameter D in the step S4 is determined according to the washing instruction and/or the data information of the laundry, and when the accumulation parameter D is different accumulation values, the determined preset condition is different; further optionally, in step S2, the accumulated parameter D is the operation duration of the pre-washing mode; the preset condition in the step S4 is the preset time duration, and by judging the prewashing time duration in the prewashing state, when it is judged that the washing machine does not need to be supplied with water, the prewashing mode operation time duration is further judged, the water supply time of the washing machine is accurately controlled, the completion of the water absorption process of the clothes to be washed is ensured, and the water amount in the washing process reaches the optimum water level in the washing process of the clothes to be washed, so that the washing effect is not influenced. Meanwhile, in the optional step S1, the pre-washing mode is that the washing machine is operated according to a set spin-stop ratio and/or a set rotation speed period; in step S2, accumulating parameter D as the number of operation cycles of the prewashing mode; in the step S4, the preset condition is a preset cycle number, and in this alternative, the limitation on the cycle number accumulation parameter in the pre-washing mode ensures that the water absorption process of the clothes to be washed is completed in the pre-washing process, so that the water amount and the water level in the washing machine cannot change in a large range in the washing process, thereby affecting the washing effect; meanwhile, the washing machine can determine the prewashing operation period according to different clothes data information by controlling the number of the prewashing mode period, so that the accurate control of the water inlet duration in the water inlet process is realized. In the specific implementation process, the washing machine rotates for 15s at a rotation speed of 50 revolutions/minute according to a rotation-stop ratio of 10s to 5s, so as to form a pre-washing period. A prewash may comprise several of the prewash cycles described above. In the specific implementation process, the data information of the clothes to be washed comprises material information of the clothes to be washed, the size of the preset condition of the accumulative parameter D is determined by distinguishing the materials of different clothes, and if the materials of the clothes are materials easy to absorb water, the clothes are washed after full water absorption is finished through the determination of the preset condition; optionally, the data information of the laundry to be washed may further include the weight or volume of the laundry to be washed; when the number of the clothes to be washed is large, the time of the clothes to be washed in the pre-washing process is prolonged through preset conditions, and the water level in the washing machine is guaranteed to meet the optimal water level of the washed clothes under the condition that the clothes to be washed fully absorb water.
Whether water needs to be fed or not can be judged according to the water quantity before prewashing and the water quantity after prewashing in the specific implementation process, the water quantity before prewashing is the preset water inflow, and the preset water inflow is the water inflow of the washing machine in the step S1. Specifically, whether the difference value between the water level before prewashing and the water level after prewashing is within a preset range or not can be adopted, when the difference value is within the preset range, the speed and the capacity of the clothes to be washed for absorbing water through prewashing are reduced to an acceptable range, and at the moment, water supplement is judged not to be needed; if the difference value is not in the pre-washing range, the water level in the washing machine is reduced more due to the water absorption of the clothes to be washed, and if the water is not supplemented, the washing effect of the clothes to be washed is influenced due to the insufficient water amount in the washing machine, so that the water supplementing is judged to be needed. The method judges whether water needs to be fed or not through the water quantity change at the starting stage and the stopping stage of the prewashing mode; in the practical process, whether water needs to be fed or not can be determined through the change of the water amount in the pre-washing process, and through testing the change of the water amount in the pre-washing process in real time, when the change of the water amount in the pre-washing process is larger than a preset threshold value, the clothes to be washed are judged to have stronger water absorption capacity, have larger influence on the water level in the washing process, and need to be fed again to supplement the water level; meanwhile, the continuous water volume change data can be drawn into a water volume change curve, and whether water needs to be fed or not is determined by determining which stage of the water volume change curve in the water absorption process of the clothes to be washed is located; when the water needs to be fed, the water can be fed after the pre-washing mode is stopped, and the water can be directly fed in the pre-washing process, so that the dynamic adjustment process of the water quantity in the washing machine is realized. Of course, it is also possible to determine whether water needs to be re-supplied according to other states of the washing machine, such as the vibration frequency of the washing machine during the pre-washing process or the conductivity of water during the pre-washing process, which is not exhaustive.
Further preferably, the step S1 of washing machine water inlet includes: controlling the washing machine to feed water to a preset water inlet amount; the preset water inflow can be determined according to a washing instruction of a user and/or data information of clothes to be washed. In the actual implementation process, the lowest water inflow can be determined according to the data information of the clothes to be washed; and judging whether the user washing instruction contains a preset water inflow or not, and when the user washing instruction does not contain the preset water inflow, determining the preset water inflow according to the lowest water inflow by the washing machine, wherein the preset water inflow is larger than the lowest water inflow. And when the washing instruction of the user comprises the preset water inflow, judging whether the preset water inflow given by the user is smaller than the minimum water inflow, and when the preset water inflow is smaller than the minimum water inflow, giving a recommended water inflow and prompting the user to reselect the preset water inflow.
For example, the data information of the laundry to be washed described in the above embodiments may be determined according to the material and/or weight and/or volume of the laundry to be washed, and the preset conditions of the water inflow data and the accumulated parameter D in the pre-washing mode operation state in the above embodiments.
Through the control to washing machine automatic water inlet process and the real-time detection whether need intake once more, realized the long dynamic control of washing machine automatic water inlet, solved among the prior art because of fixed intaking lead to when the clothing is more, the clothing water absorption capacity is big, the laundry machine moisturizing many times, the moisturizing time is longer, and the mode moisturizing through setting for the moisturizing time often can lead to intaking not enough because of the time is not enough, influences the washing effect. When the clothes are less, the water absorption amount of the clothes is less, the water replenishing frequency is less, the water replenishing time is shorter, and the set water replenishing time is usually longer than the actual water replenishing time, so that the technical problems of washing time waste and electric energy waste are caused.
