As shown in FIG. 1 , multiple washing optimization tests are performed to obtain the optimal rinsing times Y corresponding to the washing time A and the water filling time X; The weighing result G determines the washing time A, records the water filling time X of the washing machine within the washing time A, and determines the number of rinsing times Y from the washing time A and the water filling time X according to the preset correspondence. Wherein, the weighing result G is the weight of the clothes when they are not soaked in water. It should be noted that the preset correspondence relationship is obtained through multiple optimization experiments, and in the preset correspondence relationship, the washing time A and the water injection time length X correspond to the optimal number of times Y.

In the method for controlling the rinsing times of a washing machine provided in this embodiment, the rinsing times Y can be intelligently determined according to the washing time A and the water filling time X corresponding to the weight of the laundry. The method provided in this embodiment can determine or select the optimal rinsing times Y in real time according to the weight of the clothes and the water-filling time X, which effectively ensures the rinsing effect of the washing machine and avoids that the clothes are not rinsed cleanly during the rinsing process of the washing machine. and cause harm to the human body; because the method can select the number of rinsing times Y in real time, it avoids the waste of water and electricity by rinsing the clothes for many times when the clothes are rinsed cleanly; In the case of laundry, the number of rinsing times Y is intelligently selected, which satisfies the increasingly diversified comprehensive needs of users and improves the user experience.

The above-mentioned method for controlling the rinsing times of the washing machine, as shown in Figure 2, includes the following steps:

Step 1: The user selects the washing program;

Before weighing the clothes, the user selects a corresponding washing program according to the material of the clothes. For example, if the material of the clothes to be washed is cotton and linen, the user needs to select the cotton and linen washing program on the control panel of the washing machine.

Step 2: Obtain the clothing material, and select the corresponding washing program according to the clothing material;

The washing time A is determined according to the weighing result G; wherein, in each washing program, each weighing result corresponds to a washing time A, and the washing time A includes multiple gears. In actual production, different numbers of different gears can be set according to the model of the washing machine and the material of the clothes.

In this embodiment, taking the cotton and linen washing program as an example, the washing time A is divided into three different gears according to the weight of the clothes from small to large. When G≤Gmin, A=A1; when Gmin<G≤Gmax, A =A2; when Gmax<G, A=A3. Among them, A1<A2<A3.

Among them, A1=60min; A2=75min; A3=90min. In actual production, the corresponding A1, A2 and A3 in the cotton and linen program will be adaptively adjusted by random factors and other factors. A1=60min; A2=75min; A3=90min are examples for a single case, and the specific numerical values of A1, A2 and A3 are not limited by the method for controlling the number of rinsing times of the washing machine provided in this embodiment.

Step 3: Start washing; according to the weighing result G, wash the clothes for time A.

Step 31: Before the clothes are washed, the water inlet time is X1, and the water level in the washing machine reaches the predetermined water level;

Step 32: During the washing process, when the water level in the washing machine drops, the water level detection mechanism detects that the water level drops, and transmits the water level information to the controller. The controller controls the water inlet valve to open and replenishes the washing machine. When the water level reaches the predetermined water level After that, the water level detection mechanism detects the water level information and transmits the water level information to the controller. The controller controls the water inlet valve to close and stops replenishing the washing machine. The controller records the time of each replenishment. In this embodiment, the water level in the washing machine is maintained at a predetermined water level by replenishing water into the washing machine, wherein the cumulative duration of replenishing water into the washing machine is the replenishing duration X2. According to the water replenishment time of the washing machine and the flow rate of the water inlet valve, the water consumption of the clothes during the washing process can be known, and the water absorption effect of the clothes can be obtained according to the water consumption. The method for controlling the rinsing times of a washing machine provided in this example can use the water absorption effect of the clothes as a factor for judging the rinsing times Y in real time, which further ensures that the rinsing times Y and the rinsing effect of the washing machine can be intelligently determined during the rinsing process of the clothes. This avoids the waste of water and electricity by rinsing the clothes multiple times while rinsing them cleanly.

Step 4: Obtain the water injection time X;

The water filling time X is the sum of the water inlet time X1 and the water replenishment time X2. The water filling time X includes multiple gears, and each gear reflects different water absorption effects of the clothes. In this embodiment, the water injection duration X is divided into multiple gears, so that the number of rinsing times Y can be accurately judged according to the different water absorption effects of the clothes. The water filling time X is related to the model of the washing machine and the washing program selected by the user. When the model of the washing machine and the washing program selected by the user are different, the water filling time X will also change. Set different amounts of different water injection time X gears according to the type and the material of the clothing.

In this embodiment, taking the cotton and linen washing program as an example, according to the water injection duration X from short to long, the water injection duration X includes three gears, and the X values corresponding to the three gears are respectively X≤Xmin; Xmin< X≤Xmax; Xmax<X. (Xmin＜Xmax)

Among them, Xmin=100s; Xmax=130s. In actual production, the corresponding Xmin and Xmax in the cotton and linen program will be adaptively adjusted by factors such as random type. Xmin=100s; Xmax=130s is an example for a single case, and the specific numerical values of Xmin and Xmax are not limited in the method for controlling the number of rinsing times of a washing machine provided in this embodiment.

Step 5: Determine the number of rinsing times Y according to the above washing time A and the above water filling time X.

The washing time A of each gear and the water filling time X of each gear correspond to a number of washings Y.

When the gear of the washing time A is constant, the rinsing times Y increases with the increase of the water filling time X; when the gear of the water filling time X is constant, the rinsing times Y increases with the increase of the washing time A.

Table 1. Corresponding table of rinsing times

Taking the data in Table 1 as an example, when X≤Xmin, the rinsing times Y corresponding to the three gears A1, A2 and A3 of the washing time A are: 1, 2 and 3 respectively;

When Xmin<X≤Xmax, the rinsing times Y corresponding to the three gears A1, A2 and A3 of the washing time A are 2, 3 and 4 respectively;

When Xmax<X, the rinsing times Y corresponding to the three gears A1, A2 and A3 of the washing time A are 3, 4 and 5, respectively.

The data provided in Table 1 is only for the convenience of explaining the corresponding relationship between the washing time A and the optimal rinsing times Y determined by the water filling time X.

Step 6: Enter the rinsing process. According to the rinsing times Y provided in step 5, the laundry is rinsed for a corresponding number of times.

This embodiment also provides a washing machine, which adopts the above-mentioned method for controlling the rinsing times of the washing machine, and the above-mentioned method for controlling the rinsing times of the washing machine can realize the intelligent determination of the rinsing times Y; the rinsing effect of the washing machine is effectively guaranteed, and the washing machine is prevented from rinsing the clothes.
