[0025] As introduced in the background technology, in the prior art, washing machines cannot accurately predict the washing time. To solve the problem that washing machines cannot accurately predict the washing time, embodiments of the present application provide a washing time control method, device, computer-readable storage medium and washing machine.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In this embodiment, a washing time control method for a washing machine running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0028] Figure 1FIG. 1 is a flow chart of a method for controlling the washing time of a washing machine according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0029] Step S201, obtaining the current weight of the clothes in the current washing process of the washing machine, and determining a first washing time according to the current weight of the clothes, wherein the first washing time is the washing time corrected according to the weight of the clothes, and each washing process includes an initial water inlet process and at least one supplementary water inlet process;

[0030] Specifically, the present application records the weight of the clothes each time they are washed during operation of the washing machine, separates the effects of the clothes weight and water pressure on the water inlet time, makes the predicted washing time of the washing machine close to the actual time, and improves the user experience. First, the factors affecting the water inlet time are analyzed. When other factors remain unchanged, the lower the floor water pressure, the longer the water inlet time, and the water inlet time is inversely proportional to the water pressure. When the weight of the clothes changes, the total weight of the clothes absorbed by the clothes increases, and the water inlet time increases. When the water absorption rate of the clothes decreases, the amount of water absorbed by the clothes decreases, and the water inlet time is proportional to the water absorption rate of the clothes. The set water level is also proportional to the water inlet time. Therefore, before the start of this washing process, first obtain the current clothes weight, which can be obtained through the built-in weight sensor of the washing machine, and then determine the first washing time corresponding to the current clothes weight through the correction relationship between the clothes weight and the washing time.

[0031] Step S202, obtaining the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment of the last washing process, and determining a second washing time according to the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment, wherein the second washing time is the washing time corrected according to the water pressure, the water replenishment time indicates the time of the water replenishment process, the water replenishment volume indicates the volume of the water replenishment process, the water level before water replenishment indicates the water level before the water replenishment process, and the water level after water replenishment indicates the water level after the water replenishment process;

[0032] Specifically, after redetermining the washing time based on the weight of the clothes, the washing time is further redetermined based on the water pressure. The water pressure is related to the user's floor, etc. During actual application, the influence of the water pressure is determined through the water replenishment process, including the replenishment time, replenishment volume, water level before replenishment, and water level after replenishment.

[0033] Step S203, calculating the sum of the first washing time and the second washing time to obtain a total washing time, and controlling the washing machine to perform the washing for the current time to be the total washing time.

[0034] Specifically, after the washing time is re-determined according to the weight of the clothes and the water pressure, the first washing time and the second washing time are added together to obtain the latest total duration of this washing.

[0035] Through this embodiment, the current weight of the clothes in the current washing process of the washing machine is obtained, and the first washing time is determined according to the current weight of the clothes; the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment of the last washing process are obtained, and the second washing time is determined according to the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment; the sum of the first washing time and the second washing time is calculated to obtain the total time of this washing, and the washing time of the washing machine is controlled to be the total time of this washing. Compared with the prior art, the predicted washing time of the washing machine is often different from the actual washing time, and the predicted washing time is inaccurate. The present application predicts and controls the washing time of the washing machine by counting the influence of the weight of the clothes and the water pressure, so that the factors such as the weight of the clothes and the water pressure can be accurately considered, so that the predicted washing time is more accurate. Therefore, it can solve the problem that the washing machine in the prior art cannot accurately predict the washing time, and achieve the effect of accurately predicting the washing time.

[0036] In the specific implementation process, the above step S201 determines the first washing time according to the current laundry weight, which can be achieved through the following steps: Step S2011: Determine a one-to-one mapping relationship between historical laundry weight and weight water inflow time, wherein the historical laundry weight represents the laundry weight in the historical washing process, and the weight water inflow time represents the increment of water inflow time caused by the laundry weight; Step S2012: Determine the weight water inflow time corresponding to the historical laundry weight that is the same as the current laundry weight in the one-to-one mapping relationship as the first washing time. The method determines the washing time corresponding to the current laundry weight according to the predetermined one-to-one mapping relationship through the above steps, so that the washing time can be accurately determined.

[0037] Specifically, during the washing process, when water is first introduced, since the clothes are relatively dry, the clothes state and water pressure have an impact on the water introduction time. During the second water introduction, or the water replenishment process, the clothes are relatively moist, and their state has less impact on the water introduction time. The impact of the clothes state (weight) on the water introduction time can be calculated by the difference between the two water introduction times, and a one-to-one mapping relationship between the historical clothes weight and the weight water introduction time can be obtained. In the one-to-one mapping relationship, the weight water introduction time corresponding to the historical clothes weight that is the same as the current clothes weight can be determined as the first washing time.

[0038] In some optional implementations, step S2011 determines a one-to-one mapping relationship between historical clothing weight and weight water inflow time, including the following steps: an acquisition step, acquiring the first water inflow time and the supplementary water inflow time of the last washing process, and acquiring the historical clothing weight, wherein the first water inflow time represents the time of the first water inflow process, and the supplementary water inflow time represents the time of the supplementary water inflow process; a calculation step, calculating the difference between the first water inflow time and the supplementary water inflow time, and obtaining the weight water inflow time; repeatedly performing the acquisition step and the calculation step multiple times, obtaining multiple historical clothing weights and the weight water inflow time corresponding to each historical clothing weight; generating a one-to-one mapping relationship between the historical clothing weight and the weight water inflow time from each historical clothing weight and its corresponding weight water inflow time. The method can accurately determine the one-to-one mapping relationship between the historical clothing weight and the weight water inflow time through the above steps.

[0039] In the specific implementation process, when the water volume of the first water inlet process and the water replenishment process is different, the influence of the clothing state on the water inlet time can be calculated by calculating the difference in the water inlet time per unit water volume. The increment of the water inlet time caused by the weight of the clothing during the first water inlet is expressed as T 衣 , the water inflow time caused by water pressure is expressed as T 水 , T 水 It also indicates the time for replenishing water, because the time for replenishing water is only related to the water pressure. The time for the first water filling is expressed as T 进 The first water inflow time and the replenishing water inflow time can be directly obtained from the built-in timer of the washing machine. Subtract the two: T 衣 =T 进 -T 水 , the increment of water inflow time caused by the weight of the clothes, i.e., the weight water inflow time, can be obtained. Since multiple sets of data points are required to generate a one-to-one mapping relationship, the acquisition step and the calculation step are repeatedly performed multiple times to obtain multiple historical clothes weights and the weight water inflow time corresponding to each historical clothes weight, and a one-to-one mapping relationship is generated by mapping each historical clothes weight to the corresponding weight water inflow time in a one-to-one manner, which can be in the form of a data table, a curve, etc.

[0040] In some other optional embodiments, the method further includes the following steps: step S204: when the current laundry weight is different from any of the historical laundry weights, determining the weight interval of the current laundry weight and the time interval corresponding to the weight interval, and calculating the ratio of the weight interval length to the time interval length to obtain a target ratio; step S205: calculating the first washing time according to the current laundry weight and the target ratio. The method determines the washing time corresponding to the current laundry weight that is different from the historical laundry weights through the above steps, so that the first washing time can be accurately determined.

[0041] Specifically, since the historical clothing weight is multiple points, it is inevitable that there will be historical clothing weights that are different from the current clothing weight. At this time, it is necessary to determine the weight interval in which the current clothing weight is located, and the time interval corresponding to the weight interval. The difference between the current clothing weight and the minimum value of the weight interval is further recorded as the first difference, and the difference between the first washing time to be solved and the minimum value of the time interval is recorded as the second difference. The ratio of the first difference to the second difference is recorded as the second target ratio. By making the target ratio the same as the second target ratio, the first washing time can be solved.

[0042] In the specific implementation process, the above step S202 determines the second washing time according to the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment, which can be achieved by the following steps: Step S2021: Calculate the difference between the water level after water replenishment and the water level before water replenishment to obtain the water level difference; Step S2022: Calculate the product of the water replenishment time and the water replenishment volume, and calculate the ratio of the product to the water level difference; Step S2023: Obtain the number of times of the water replenishment process, calculate the product of the ratio and the number of times, and obtain the second washing time. The method determines the second washing time through the above steps, so that the washing time can be corrected according to the water pressure.

[0043] Specifically, the second washing time can be calculated by the formula L1 and L2 are the water level before and after water replenishment, respectively. 补 Indicates the duration of water replenishment, L 进 Represents the water replenishment volume. The time T of this water replenishment can be calculated from the above formula. 水 If the water is replenished more than once, the second washing time can be obtained by calculating the product of the water replenishment times N and the second washing time. The total adjustment time needs to be multiplied by the difference between the original set time and the second washing time, that is, (T 设 -T 水 )*N.

[0044] In some other optional implementations, the above step S202 obtains the water replenishment volume of the last washing process, which can be achieved by the following steps: step S2024: obtaining the water absorption coefficient and the historical weight of the clothes in the last washing process, wherein the water absorption coefficient represents the magnitude of the water absorption performance of the clothes; step S2025: calculating the product of the water absorption coefficient and the historical weight of the clothes in the last washing process to obtain the water replenishment volume. The method can accurately calculate the water replenishment volume through the above steps.

[0045] In the specific implementation process, the influence of clothing weight and water absorption rate on water absorption coefficient (AR) is measured uniformly, and its total weight of water absorption (W 水 ) and total volume of water absorbed (L 水 ) is L 水 =W 水 =W 干 *AR,W 干 Indicates the weight of dry laundry.

[0046] In some other optional implementations, after controlling the current washing time of the washing machine to be the total washing time of this time, the method further includes the following steps: using the current laundry weight as the historical laundry weight and the total washing time of this time as the weight water inflow time, generating a one-to-one mapping relationship between the historical laundry weight and the weight water inflow time, wherein the historical laundry weight represents the laundry weight in the historical washing process, and the weight water inflow time represents the water inflow time increment caused by the laundry weight. Through the above steps, the method stores each washing time data in a one-to-one mapping relationship, which can increase the amount of data and facilitate the subsequent further correction of the washing time.

[0047] Specifically, the current laundry weight and the corresponding first washing time continue to be included in the one-to-one mapping relationship.

[0048] In the specific implementation process, before calculating the above time, data recording and preprocessing steps are also included: 1. Pre-data recording stage: First, since the washing time of the washing machine can be collected by the designer in advance to determine the influence of the weight of the clothes, the type of clothes, etc. on the washing time, the influence of the weight on the time can be recorded in advance inside the chip, which can greatly improve the speed of the washing machine to collect data when the user uses the washing machine; 2. Laundry data collection stage: Although the data recorded in the first stage can already perform certain compensation operations on the washing time of the washing machine, since the clothes worn by the user will not completely match the type of clothes during the test, the data must be collected and adjusted again when the user uses the washing machine. Since the style of clothing worn by each family will not change suddenly, the data collection will gradually stabilize, and eventually the time obtained by the washing machine time adjustment algorithm will be close to the real time; 3. Data sorting stage: During the washing process, the program will automatically record the weight of the clothes washed by the washing machine, the time required for each water replenishment, the time required for dehydration, and other key data. These data will be stored in the mainboard memory after each washing is completed, waiting for data call; 4. Data processing stage: separate the influence of clothing weight and floor water pressure on water inlet time, first determine the one-to-one mapping relationship between historical clothing weight and weight water inlet time, and determine the first washing time corresponding to the current clothing weight according to the one-to-one mapping relationship, and then determine the second washing time according to the influence of water pressure, and finally calculate the sum of the first washing time and the second washing time to get the total washing time; 5. Continuously record data to correct the one-to-one mapping relationship between historical clothing weight and weight water inlet time, so as to make the predicted washing time more accurate.

[0049] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the washing time control method of the washing machine of the present application will be described in detail below in combination with specific embodiments.

[0050] This embodiment relates to a specific method for controlling the washing time of a washing machine. Figure 2 As shown, the following steps are included:

[0051] Step S1: Start;

[0052] Step S2: weighing the laundry;

[0053] Step S3: Record the weight of the clothes and the washing method;

[0054] Step S4: executing the water inlet procedure and recording the water inlet time (first washing time);

[0055] Step S5: washing and recording washing time;

[0056] Step S6: dehydrating and recording the duration, and correcting the washing time (second washing time);

[0057] Step S7: Collect the total duration (total duration of this washing);

[0058] Step S8: Collect all information and record it in a memory that is retained when power is off;

[0059] Step S9: Calculate the effect of clothing weight on the duration of all processes;

[0060] Step S10: Compare with the preset influencing factor and adjust the influencing factor (water absorption coefficient);

[0061] Step S11: Record the user's water intake time, calculate the total washing time, and display it during the next wash.

[0062] Figure 3 A schematic diagram of factors affecting washing time is shown, where the total washing time includes water inlet time, dehydration time and washing time. The water inlet time is related to the floor water pressure, clothing weight, clothing type and preset water level, the dehydration time is related to clothing weight and clothing type, and the washing time is related to the preset washing time and the preset washing method.

[0063] Figure 4 A washing time calculation process is shown. First, the washing time (first washing time) is determined by the weight of the clothes according to the one-to-one mapping relationship between the historical clothes weight and the weight water intake time (as shown in the figure in the upper right corner, the horizontal axis is the clothes weight, the vertical axis is the washing time, the preset curve is the one-to-one mapping relationship between the historical clothes weight and the weight water intake time, and the updated curve is the curve updated according to the data collected this time). Then, the water intake time (second washing time) is determined by factors such as the floor and water pressure (this application mainly considers water pressure). The total water intake time is the sum of the first washing time and the second washing time. In actual application, it also includes additional water intake time caused by unexpected factors.

[0064] The present application embodiment also provides a washing time control device for a washing machine. It should be noted that the washing time control device for the washing machine of the present application embodiment can be used to execute the washing time control method for the washing machine provided by the present application embodiment. The device is used to implement the above-mentioned embodiments and preferred embodiments, and the descriptions have been made and will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware of a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware is also possible and conceived.

[0065] The following is an introduction to the washing time control device of the washing machine provided in the embodiment of the present application.

[0066] Figure 5Schematic diagram of a washing time control device for a washing machine according to an embodiment of the present application. Figure 5 As shown, the device comprises:

[0067] A first determining unit 10 is used to obtain the current weight of the clothes in the current washing process of the washing machine, and determine a first washing time according to the current weight of the clothes, wherein the first washing time is the washing time corrected according to the weight of the clothes, and each washing process includes an initial water inlet process and at least one supplementary water inlet process;

[0068] Specifically, the present application records the weight of the clothes each time they are washed during operation of the washing machine, separates the effects of the clothes weight and water pressure on the water inlet time, makes the predicted washing time of the washing machine close to the actual time, and improves the user experience. First, the factors affecting the water inlet time are analyzed. When other factors remain unchanged, the lower the floor water pressure, the longer the water inlet time, and the water inlet time is inversely proportional to the water pressure. When the weight of the clothes changes, the total weight of the clothes absorbed by the clothes increases, and the water inlet time increases. When the water absorption rate of the clothes decreases, the amount of water absorbed by the clothes decreases, and the water inlet time is proportional to the water absorption rate of the clothes. The set water level is also proportional to the water inlet time. Therefore, before the start of this washing process, first obtain the current clothes weight, which can be obtained through the built-in weight sensor of the washing machine, and then determine the first washing time corresponding to the current clothes weight through the correction relationship between the clothes weight and the washing time.

[0070] Specifically, after redetermining the washing time based on the weight of the clothes, the washing time is further redetermined based on the water pressure. The water pressure is related to the user's floor, etc. During actual application, the influence of the water pressure is determined through the water replenishment process, including the replenishment time, replenishment volume, water level before replenishment, and water level after replenishment.

[0071] The control unit 30 is used to calculate the sum of the first washing time and the second washing time to obtain a total washing time, and control the washing machine to have a washing time equal to the total washing time.

[0072] Specifically, after the washing time is re-determined according to the weight of the clothes and the water pressure, the first washing time and the second washing time are added together to obtain the latest total duration of this washing.

[0073] Through this embodiment, the current weight of the clothes in the current washing process of the washing machine is obtained, and the first washing time is determined according to the current weight of the clothes; the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment of the last washing process are obtained, and the second washing time is determined according to the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment; the sum of the first washing time and the second washing time is calculated to obtain the total time of this washing, and the washing time of the washing machine is controlled to be the total time of this washing. Compared with the prior art, the predicted washing time of the washing machine is often different from the actual washing time, and the predicted washing time is inaccurate. The present application predicts and controls the washing time of the washing machine by counting the influence of the weight of the clothes and the water pressure, so that the factors such as the weight of the clothes and the water pressure can be accurately considered, so that the predicted washing time is more accurate. Therefore, it can solve the problem that the washing machine in the prior art cannot accurately predict the washing time, and achieve the effect of accurately predicting the washing time.

[0074] In the specific implementation process, the first determination unit includes a first determination module and a second determination module. The first determination module is used to determine a one-to-one mapping relationship between historical laundry weight and weight water inflow time, wherein the historical laundry weight represents the laundry weight in the historical washing process, and the weight water inflow time represents the increment of water inflow time caused by the laundry weight; the second determination module is used to determine the weight water inflow time corresponding to the historical laundry weight that is the same as the current laundry weight in the one-to-one mapping relationship as the first washing time. The device determines the washing time corresponding to the current laundry weight according to the predetermined one-to-one mapping relationship through the above steps, so that the washing time can be accurately determined.

[0075] Specifically, during the washing process, when water is first introduced, since the clothes are relatively dry, the clothes state and water pressure have an impact on the water introduction time. During the second water introduction, or the water replenishment process, the clothes are relatively moist, and their state has less impact on the water introduction time. The impact of the clothes state (weight) on the water introduction time can be calculated by the difference between the two water introduction times, and a one-to-one mapping relationship between the historical clothes weight and the weight water introduction time can be obtained. In the one-to-one mapping relationship, the weight water introduction time corresponding to the historical clothes weight that is the same as the current clothes weight can be determined as the first washing time.

[0076] In some optional embodiments, the first determination module includes an acquisition submodule, a calculation submodule, an execution substep and a generation submodule, wherein the acquisition submodule is used to execute the acquisition step, acquire the first water inlet time and the supplementary water inlet time of the last washing process, and acquire the historical clothing weight, wherein the first water inlet time represents the time of the first water inlet process, and the supplementary water inlet time represents the time of the supplementary water inlet process; the calculation submodule is used to execute the calculation step, calculate the difference between the first water inlet time and the supplementary water inlet time, and obtain the weight water inlet time; the execution substep is used to repeatedly execute the acquisition step and the calculation step multiple times, and obtain multiple historical clothing weights and the weight water inlet time corresponding to each historical clothing weight; the generation submodule is used to generate a one-to-one mapping relationship between the historical clothing weight and the weight water inlet time from each historical clothing weight and its corresponding weight water inlet time. The device can accurately determine the one-to-one mapping relationship between the historical clothing weight and the weight water inlet time through the above steps.

[0077] In the specific implementation process, when the water volume of the first water inlet process and the water replenishment process is different, the influence of the clothing state on the water inlet time can be calculated by calculating the difference in the water inlet time per unit water volume. The increment of the water inlet time caused by the weight of the clothing during the first water inlet is expressed as T 衣 , the water inflow time caused by water pressure is expressed as T 水 , T 水 It also indicates the time for replenishing water, because the time for replenishing water is only related to the water pressure. The time for the first water filling is expressed as T 进 The first water inflow time and the replenishing water inflow time can be directly obtained from the built-in timer of the washing machine. Subtract the two: T 衣 =T 进 -T 水 , the increment of water inflow time caused by the weight of the clothes, i.e., the weight water inflow time, can be obtained. Since multiple sets of data points are required to generate a one-to-one mapping relationship, the acquisition step and the calculation step are repeatedly performed multiple times to obtain multiple historical clothes weights and the weight water inflow time corresponding to each historical clothes weight, and a one-to-one mapping relationship is generated by mapping each historical clothes weight to the corresponding weight water inflow time in a one-to-one manner, which can be in the form of a data table, a curve, etc.

[0078] In some other optional embodiments, the device further includes a first calculation module and a second calculation module, wherein the first calculation module is used to determine the weight interval of the current clothing weight and the time interval corresponding to the weight interval when the current clothing weight is different from any of the historical clothing weights, and calculate the ratio of the weight interval length to the time interval length to obtain a target ratio; and the second calculation module is used to calculate the first washing time based on the current clothing weight and the target ratio. The device determines the washing time corresponding to the current clothing weight that is different from the historical clothing weights through the above steps, so that the first washing time can be accurately determined.

[0079] Specifically, since the historical clothing weight is multiple points, it is inevitable that there will be historical clothing weights that are different from the current clothing weight. At this time, it is necessary to determine the weight interval in which the current clothing weight is located, and the time interval corresponding to the weight interval. The difference between the current clothing weight and the minimum value of the weight interval is further recorded as the first difference, and the difference between the first washing time to be solved and the minimum value of the time interval is recorded as the second difference. The ratio of the first difference to the second difference is recorded as the second target ratio. By making the target ratio the same as the second target ratio, the first washing time can be solved.

[0080] In the specific implementation process, the second determination unit includes a third calculation module, a fourth calculation module and a fifth calculation module. The third calculation module is used to calculate the difference between the water level after the water replenishment and the water level before the water replenishment to obtain the water level difference; the fourth calculation module is used to calculate the product of the water replenishment time and the water replenishment volume, and calculate the ratio of the product to the water level difference; the fifth calculation module is used to obtain the number of times of the water replenishment process, calculate the product of the ratio and the number of times, and obtain the second washing time. The device determines the second washing time through the above steps, so that the washing time can be corrected according to the water pressure.

[0081] Specifically, the second washing time can be calculated by the formula L1 and L2 are the water level before and after water replenishment, respectively. 补 Indicates the duration of water replenishment, L 进 Represents the water replenishment volume. The time T of this water replenishment can be calculated from the above formula. 水 If the water is replenished more than once, the second washing time can be obtained by calculating the product of the water replenishment times N and the second washing time. The total adjustment time needs to be multiplied by the difference between the original set time and the second washing time, that is, (T 设 -T 水 )*N.

[0082] In some other optional embodiments, the second determination unit includes an acquisition module and a sixth calculation module, the acquisition module is used to acquire the water absorption coefficient and the historical weight of the clothes in the last washing process, wherein the water absorption coefficient represents the magnitude of the water absorption performance of the clothes; the sixth calculation module is used to calculate the product of the water absorption coefficient and the historical weight of the clothes in the last washing process to obtain the water replenishment volume. The device can accurately calculate the water replenishment volume through the above steps.

[0083] In the specific implementation process, the influence of clothing weight and water absorption rate on water absorption coefficient (AR) is measured uniformly, and its total weight of water absorption (W 水 ) and total volume of water absorbed (L 水 ) is L 水 =W 水 =W 干 *AR,W 干 Indicates the weight of dry laundry.

[0084] In some other optional embodiments, after controlling the current washing time of the washing machine to be the total washing time of this time, the device further includes a generating unit for using the current laundry weight as the historical laundry weight and the total washing time of this time as the weight water inflow time to generate a one-to-one mapping relationship between the historical laundry weight and the weight water inflow time, wherein the historical laundry weight represents the laundry weight in the historical washing process, and the weight water inflow time represents the water inflow time increment caused by the laundry weight. The device stores each washing time data in a one-to-one mapping relationship through the above steps, which can increase the amount of data and facilitate the subsequent further correction of the washing time.

[0085] Specifically, the current laundry weight and the corresponding first washing time continue to be included in the one-to-one mapping relationship.

[0086] In the specific implementation process, before calculating the above time, data recording and preprocessing steps are also included: 1. Pre-data recording stage: First, since the washing time of the washing machine can be collected by the designer in advance to determine the influence of the weight of the clothes, the type of clothes, etc. on the washing time, the influence of the weight on the time can be recorded in advance inside the chip, which can greatly improve the speed of the washing machine to collect data when the user uses the washing machine; 2. Laundry data collection stage: Although the data recorded in the first stage can already perform certain compensation operations on the washing time of the washing machine, since the clothes worn by the user will not completely match the type of clothes during the test, the data must be collected and adjusted again when the user uses the washing machine. Since the style of clothing worn by each family will not change suddenly, the data collection will gradually stabilize, and eventually the time obtained by the washing machine time adjustment algorithm will be close to the real time; 3. Data sorting stage: During the washing process, the program will automatically record the weight of the clothes washed by the washing machine, the time required for each water replenishment, the time required for dehydration, and other key data. These data will be stored in the mainboard memory after each washing is completed, waiting for data call; 4. Data processing stage: separate the influence of clothing weight and floor water pressure on water inlet time, first determine the one-to-one mapping relationship between historical clothing weight and weight water inlet time, and determine the first washing time corresponding to the current clothing weight according to the one-to-one mapping relationship, and then determine the second washing time according to the influence of water pressure, and finally calculate the sum of the first washing time and the second washing time to get the total washing time; 5. Continuously record data to correct the one-to-one mapping relationship between historical clothing weight and weight water inlet time, so as to make the predicted washing time more accurate.

[0087] The washing time control device of the washing machine includes a processor and a memory, wherein the first determination unit, the second determination unit and the control unit are stored in the memory as program units, and the processor executes the program units stored in the memory to realize corresponding functions. The modules are all located in the same processor; or, the modules are located in different processors in any combination.

[0088] The processor includes a kernel, which retrieves the corresponding program unit from the memory. One or more kernels can be set, and the problem that the washing machine cannot accurately predict the washing time can be solved by adjusting the kernel parameters.

[0089] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.

[0091] Specifically, the washing time control method of the washing machine includes:

[0092] Step S201, obtaining the current weight of the clothes in the current washing process of the washing machine, and determining a first washing time according to the current weight of the clothes, wherein the first washing time is the washing time corrected according to the weight of the clothes, and each washing process includes an initial water inlet process and at least one supplementary water inlet process;

[0093] Specifically, the present application records the weight of the clothes each time they are washed during operation of the washing machine, separates the effects of the clothes weight and water pressure on the water inlet time, makes the predicted washing time of the washing machine close to the actual time, and improves the user experience. First, the factors affecting the water inlet time are analyzed. When other factors remain unchanged, the lower the floor water pressure, the longer the water inlet time, and the water inlet time is inversely proportional to the water pressure. When the weight of the clothes changes, the total weight of the clothes absorbed by the clothes increases, and the water inlet time increases. When the water absorption rate of the clothes decreases, the amount of water absorbed by the clothes decreases, and the water inlet time is proportional to the water absorption rate of the clothes. The set water level is also proportional to the water inlet time. Therefore, before the start of this washing process, first obtain the current clothes weight, which can be obtained through the built-in weight sensor of the washing machine, and then determine the first washing time corresponding to the current clothes weight through the correction relationship between the clothes weight and the washing time.

[0094] Step S202, obtaining the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment of the last washing process, and determining a second washing time according to the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment, wherein the second washing time is the washing time corrected according to the water pressure, the water replenishment time indicates the time of the water replenishment process, the water replenishment volume indicates the volume of the water replenishment process, the water level before water replenishment indicates the water level before the water replenishment process, and the water level after water replenishment indicates the water level after the water replenishment process;

[0095] Specifically, after redetermining the washing time based on the weight of the clothes, the washing time is further redetermined based on the water pressure. The water pressure is related to the user's floor, etc. During actual application, the influence of the water pressure is determined through the water replenishment process, including the replenishment time, replenishment volume, water level before replenishment, and water level after replenishment.

[0096] Step S203, calculating the sum of the first washing time and the second washing time to obtain a total washing time, and controlling the washing machine to perform the washing for the current time to be the total washing time.

[0097] Specifically, after the washing time is re-determined according to the weight of the clothes and the water pressure, the first washing time and the second washing time are added together to obtain the latest total duration of this washing.

[0098] An embodiment of the present invention provides a washing machine, including a processor, a memory, and a program stored in the memory and executable on the processor, wherein the processor implements at least the following steps when executing the program:

[0100] Specifically, the present application records the weight of the clothes each time they are washed during operation of the washing machine, separates the effects of the clothes weight and water pressure on the water inlet time, makes the predicted washing time of the washing machine close to the actual time, and improves the user experience. First, the factors affecting the water inlet time are analyzed. When other factors remain unchanged, the lower the floor water pressure, the longer the water inlet time, and the water inlet time is inversely proportional to the water pressure. When the weight of the clothes changes, the total weight of the clothes absorbed by the clothes increases, and the water inlet time increases. When the water absorption rate of the clothes decreases, the amount of water absorbed by the clothes decreases, and the water inlet time is proportional to the water absorption rate of the clothes. The set water level is also proportional to the water inlet time. Therefore, before the start of this washing process, first obtain the current clothes weight, which can be obtained through the built-in weight sensor of the washing machine, and then determine the first washing time corresponding to the current clothes weight through the correction relationship between the clothes weight and the washing time.

[0101] Step S202, obtaining the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment of the last washing process, and determining a second washing time according to the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment, wherein the second washing time is the washing time corrected according to the water pressure, the water replenishment time indicates the time of the water replenishment process, the water replenishment volume indicates the volume of the water replenishment process, the water level before water replenishment indicates the water level before the water replenishment process, and the water level after water replenishment indicates the water level after the water replenishment process;

[0102] Specifically, after redetermining the washing time based on the weight of the clothes, the washing time is further redetermined based on the water pressure. The water pressure is related to the user's floor, etc. During actual application, the influence of the water pressure is determined through the water replenishment process, including the replenishment time, replenishment volume, water level before replenishment, and water level after replenishment.

[0103] Step S203, calculating the sum of the first washing time and the second washing time to obtain a total washing time, and controlling the washing machine to perform the washing for the current time to be the total washing time.

[0104] Specifically, after the washing time is re-determined according to the weight of the clothes and the water pressure, the first washing time and the second washing time are added together to obtain the latest total duration of this washing.

[0106] The present application also provides a computer program product, including a computer program, which, when executed by a processor, implements the steps of the method described in each embodiment of the present application:

[0107] Step S201, obtaining the current weight of the clothes in the current washing process of the washing machine, and determining a first washing time according to the current weight of the clothes, wherein the first washing time is the washing time corrected according to the weight of the clothes, and each washing process includes an initial water inlet process and at least one supplementary water inlet process;

[0108] Specifically, the present application records the weight of the clothes each time they are washed during operation of the washing machine, separates the effects of the clothes weight and water pressure on the water inlet time, makes the predicted washing time of the washing machine close to the actual time, and improves the user experience. First, the factors affecting the water inlet time are analyzed. When other factors remain unchanged, the lower the floor water pressure, the longer the water inlet time, and the water inlet time is inversely proportional to the water pressure. When the weight of the clothes changes, the total weight of the clothes absorbed by the clothes increases, and the water inlet time increases. When the water absorption rate of the clothes decreases, the amount of water absorbed by the clothes decreases, and the water inlet time is proportional to the water absorption rate of the clothes. The set water level is also proportional to the water inlet time. Therefore, before the start of this washing process, first obtain the current clothes weight, which can be obtained through the built-in weight sensor of the washing machine, and then determine the first washing time corresponding to the current clothes weight through the correction relationship between the clothes weight and the washing time.

[0109] Step S202, obtaining the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment of the last washing process, and determining a second washing time according to the water replenishment time, water replenishment volume, water level before water replenishment and water level after water replenishment, wherein the second washing time is the washing time corrected according to the water pressure, the water replenishment time indicates the time of the water replenishment process, the water replenishment volume indicates the volume of the water replenishment process, the water level before water replenishment indicates the water level before the water replenishment process, and the water level after water replenishment indicates the water level after the water replenishment process;

[0110] Specifically, after redetermining the washing time based on the weight of the clothes, the washing time is further redetermined based on the water pressure. The water pressure is related to the user's floor, etc. During actual application, the influence of the water pressure is determined through the water replenishment process, including the replenishment time, replenishment volume, water level before replenishment, and water level after replenishment.
