[0029] Embodiment 1

[0030] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart showing the main steps of a method for controlling a washing machine according to an embodiment of the present invention. Figure 1 As shown, the control method of the washing machine in the embodiment of the present invention mainly includes the following steps S1 to S4.

[0031] Step S1, obtaining an estimated dehydration amount based on the moisture content of the clothes set in the washing machine and the weight of the clothes to be washed in the washing machine;

[0032] In this embodiment, the moisture content of the clothes is the percentage of water in the clothes after the set dehydration program is completed. For example, the moisture content of the clothes can be set to 55%, so the expected dehydration amount = moisture content of the clothes * the weight of the clothes before dehydration. The weight of the clothes to be washed in the washing machine is the weight of the clothes to be washed in a dry state obtained by a weighing program after the clothes to be washed are placed in the inner drum of the washing machine and before the water inlet system is turned on. Specifically, a weight sensor is set at the bottom of the barrel of the washing machine to obtain weight data.

[0033] Step S2, obtaining the actual water inflow and the actual water outflow of the washing machine during the dehydration stage, and obtaining the actual dehydration amount based on the actual water inflow and the actual water outflow;

[0034] In this embodiment, there may be a deviation between the actual water intake and the actual water output of the washing machine during the dehydration stage. Therefore, the difference between the actual water intake and the actual water output is the actual dehydration amount. The actual dehydration amount can be obtained multiple times at preset times or in real time during the dehydration stage.

[0035] In one embodiment, obtaining the actual water intake and actual water output of the washing machine during the dehydration stage includes: a first flow meter and a second flow meter are respectively provided at the water inlet and water outlet of the washing machine, and the actual water intake and actual water output of the washing machine during the dehydration stage are obtained based on the first flow meter, and the actual water output of the washing machine during the dehydration stage is obtained based on the second flow meter.

[0036] In this embodiment, the water inflow and water outflow of the washing machine in real time and / or within a preset time period can be obtained by the flow meter to obtain the actual water inflow and the actual water outflow.

[0037] Step S3, comparing the actual dehydration amount with the estimated dehydration amount to obtain a first comparison result;

[0038] In one embodiment, based on the first comparison result, controlling the dehydration stage of the washing machine includes: if the first comparison result is that the actual dehydration amount is greater than the expected dehydration amount, then stopping the dehydration; if the first comparison result is that the actual dehydration amount is less than or equal to the expected dehydration amount, then extending the dehydration time and / or increasing the dehydration speed. In this embodiment, when the first comparison result is that the actual dehydration amount is greater than the expected dehydration amount, it indicates that the current dehydration amount has at least reached the expected dehydration amount, so the dehydration program can be stopped; when the actual dehydration amount is less than or equal to the expected dehydration amount, it indicates that the current dehydration amount has not reached the expected dehydration amount, so it is necessary to continue dehydration until the expected dehydration amount is met. Specifically, the expected dehydration amount requirement is met by extending the dehydration time and / or increasing the dehydration speed, so that the dehydration effect is better.

[0039] Step S4, based on the first comparison result, controlling the dehydration stage of the washing machine. In this embodiment, if the first comparison result is that the actual dehydration amount is significantly different from the expected dehydration amount, it is determined that the dehydration effect does not meet the user's needs, and the dehydration program is continued until the user's needs are met.

[0040] In one embodiment, whether the washing machine operates normally during the operation stage is determined based on the actual water intake and / or actual water output during the operation stage of the washing machine, and the operation stage includes one of a washing stage, a rinsing stage, and a dehydration stage.

[0041] In this embodiment, when obtaining the actual water intake and / or actual water output of the washing machine during the operation phase, real-time collection can be used, or fixed-point collection can be performed at a preset time or within a preset time period. This method can accurately distinguish whether each operation phase of the washing machine is normal.

[0042] In one embodiment, judging whether the washing machine operates normally during the operation stage based on the actual water intake and / or actual water discharge of the washing machine includes: judging whether the water intake system of the washing machine fails, and / or judging whether the drainage system of the washing machine fails.

[0043] In this embodiment, while ensuring the accuracy of the judgment result, it is only necessary to use the actual water intake and / or actual water output to determine whether at least one of the operation stages of the washing machine is operating normally, which greatly reduces the amount of data running the current program, improves its operating speed, and reduces the manufacturing cost of the washing machine.

[0044] Among them, the water inlet system includes a water pipe, a faucet, an inner barrel of a washing machine, a washing tub, a drainage pump and a pipe connecting the outer barrel and the machine cover. The water inlet system is the main control of the washing machine. The drainage system includes a water pump, a water pipe, a water inlet pipe and a drain. The drainage system is mainly used to drain the water in the water inlet pipe. The drainage system is an auxiliary control system of the washing machine. Specifically, a large amount of water is used when washing clothes. If the actual water inlet exceeds or does not reach the selected water level, when the water level is too high, it may damage the parts of the washing machine. When the actual water inlet does not reach the selected water level, there will be insufficient water, which will affect the washing and rinsing performance. Therefore, it is necessary to determine whether the water inlet system of the washing machine is faulty. At the same time, if the water in the inner barrel of the washing machine is not drained in time, the washing machine will not work properly. Therefore, it is necessary to determine whether the drainage system of the washing machine is faulty. In addition, when the water inlet system and / or drainage system of the washing machine fails, an alarm is issued to remind the user of the fault location of the washing machine.

[0045] In one embodiment, the washing stage and the rinsing stage both include a water intake process and a water discharge process, and the dehydration stage of the washing machine includes a water discharge process; the determining whether the drainage system of the washing machine fails includes: during the water discharge process, comparing the actual water output with the set water output, and / or comparing the actual water intake with the set water intake;

[0046] If the actual water output is greater than the set water output or the actual water output is less than the set water output, and / or the actual water inflow is greater than the set water inflow, it is confirmed that the drainage system of the washing machine is faulty.

[0047] In this embodiment, when the actual water output is greater than the set water output, it indicates that the amount of water discharged by the washing machine at the current stage is large. When the actual water output is less than the set water output, it indicates that the drainage system may be blocked, for example, the drainage pipe of the washing machine is blocked and the sewage cannot be discharged normally, or the internal filter of the washing machine has not been cleaned for a long time and is blocked, which in turn causes the actual water output counted by the second flowmeter to be less than the set water output. The set water inlet can be set to 0 liters. When the actual water inlet is greater than 0 liters, it indicates that during the drainage process, the water inlet system of the washing machine is turned on, and the phenomenon of water inlet while draining water occurs.

[0048] In one embodiment, the determining whether the water inlet system of the washing machine fails comprises: during the water inlet process, comparing the actual water inlet volume with the set water inlet volume, and / or comparing the actual water outlet volume with the set water outlet volume;

[0049] If the actual water inflow is greater than the set water inflow or the actual water inflow is less than the set water inflow, and the actual water outflow is greater than the set water outflow, it is confirmed that the water inflow system of the washing machine is faulty.

[0050] In this embodiment, the water intake is set to a suitable number of liters according to the weight of the laundry. Once the water in the water tub exceeds the overflow port, the water will flow out from the top of the water tub. The overflow of the top of the washing machine water tub is likely to affect the electrical components of the washing machine, especially the insulation performance of the electrical components of the washing machine. Therefore, it is necessary to determine whether the actual water intake is greater than the set water intake. If the actual water intake is greater than the set water intake, it indicates that the water intake of the washing machine is too much at the current stage.

[0051] The set water output can be set to 0 liters. When the actual water output is greater than 0 liters, it indicates that the washing machine has drainage during the water intake process.

[0052] When the actual water inflow is less than the set water inflow, it indicates that the water inflow system of the washing machine may be blocked. For example, the internal filter of the washing machine has not been cleaned for a long time, resulting in blockage, and water cannot flow normally, which means that water cannot enter the inner drum of the washing machine, and / or there is a leak in the pipes in the water inlet system. For example, there is a crack between the pipes of the water inlet system and the first flow meter, resulting in the actual water inflow counted by the first flow meter being less than the set water inflow. At this time, the water volume in the washing machine is insufficient, and a low cleaning ratio, retained foam and poor rinsing performance may occur.

[0053] In one embodiment, the washing stage further includes a washing process, during which judging whether a washing system of the washing machine fails based on the actual water output and / or the actual water intake comprises: judging whether the actual water output is greater than 0 liters and / or judging whether the actual water intake is greater than 0 liters;

[0054] If the actual water output is greater than 0 liter, and / or it is determined that the actual water intake is greater than 0 liter, it is confirmed that the washing system of the washing machine has a fault.

[0055] In this embodiment, there is no water intake and drainage process during the washing process. Therefore, when the actual water output is greater than 0 liters, it indicates that water has passed through the second flow meter of the washing machine during the washing process, that is, the drainage system is in the open state, and the drainage system is faulty at this time; when the actual water intake is greater than 0 liters, it indicates that water has passed through the first flow meter of the washing machine during the washing process, that is, the water intake system is in the open state, and the water intake system is faulty.

[0056] In the prior art, an empirical dehydration control method is generally used, that is, the wet clothes placed in the washing tub are dehydrated at a low speed for a fixed time and a fixed number of times. However, the present application is based on the above steps S1-S4, and the estimated dehydration data obtained is more accurate. It is only necessary to weigh the clothes before washing, calculate the estimated dehydration amount of the clothes according to the set moisture content, and accurately control the dehydration stage of the washing machine by comparing the estimated dehydration amount and the actual dehydration amount, so as to achieve dynamic adjustment under a fixed program, prevent the clothes from being worn due to excessive dehydration, and avoid the waste of electric energy. Furthermore, it is also possible to judge whether the washing machine is operating normally during the operation stage based on the actual water intake and / or actual water output of the washing machine, so that the user can understand the status of the washing machine in time and improve the user experience.

[0057] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.
