TECHNICAL FIELD

[0001] The present application relates to the technical field of smart home, and particularly provides a control method for a washing device. BACKGROUND

[0002] A washing machine is a common household laundry washing device. According to the washing mode, the washing machine can be roughly divided into a pulsator washing machine and a drum washing machine. Taking the pulsator washing machine as an example, in order to meet the use requirements of users, the pulsator washing machine is provided with a heating program and a soaking program. The water is heated before washing, or the clothes are soaked, so as to improve the washing effect.

[0003] However, in the actual use process, if the user selects the heating program and the soaking program at the same time, the heating program with the target heating time and the soaking program with the target soaking time need to be run respectively, which greatly prolongs the total running time and reduces the user experience.

[0004] Therefore, there is a need in the art for a new control method for a washing device to solve the above problems. SUMMARY

[0005] In order to solve the above problems in the prior art, that is, to solve the problem that the total running time is prolonged when the existing washing device selects the heating program and the soaking program at the same time, the present application provides a control method for a washing device, which comprises the following steps: in the case that the heating program and the soaking program are set at the same time in the washing device, obtaining a target heating time; obtaining a target soaking time; comparing the target heating time and the target soaking time; according to the comparison result, selectively determining the target heating time or the target soaking time as the total running time of the heating program and the soaking program; and executing the heating program and the soaking program according to the total running time.

[0006] In the preferred technical scheme of the above control method, the step of "according to the comparison result, selectively determining the target heating time or the target soaking time as the total running time of the heating program and the soaking program" specifically comprises: if the target heating time is greater than the target soaking time, obtaining a target washing water level; obtaining a target washing temperature; according to the target washing water level and the target washing temperature, judging a preset type to which the case that the target heating time is greater than the target soaking time belongs; and according to the judgment result, selectively determining the target heating time or the target soaking time as the total running time.

[0008] In the preferred technical scheme of the control method, the step of selectively determining the target heating time or the target soaking time as the total running time according to the judgment result specifically includes: in the case that it is determined that the case that the target heating time is greater than the target soaking time belongs to the first preset type, determining the target soaking time as the total running time; the step of executing the heating program and the soaking program according to the total running time specifically includes: executing the heating program and the soaking program according to the target soaking time.

[0009] In the preferred technical scheme of the control method, the step of executing the heating program and the soaking program according to the target soaking time specifically includes: controlling the washing device to fill water to a second preset water level, wherein the second preset water level is less than the target washing water level; after the washing device fills water to the second preset water level, controlling the washing device to execute a heating operation and start counting an actual heating time; after the washing water is heated to the target washing temperature, controlling the washing device to continue to fill water to the target washing water level; during or after the process of controlling the washing device to continue to fill water to the target washing water level, controlling the washing device to continue to execute the heating operation and continue to count the actual heating time until the counted actual heating time reaches the target soaking time.

[0010] In the preferred technical solution of the control method, the control method further comprises: during the step of controlling the washing device to perform the heating operation, taking the first water flow intensity of the heating program as the water flow intensity during the execution of the heating operation; during the step of controlling the washing device to continue to fill water to the target washing water level, taking the first water flow intensity of the heating program as the water flow intensity during the execution of the filling water operation; during the step of controlling the washing device to continue to perform the heating operation after the step of controlling the washing device to continue to fill water to the target washing water level, taking the second water flow intensity of the soaking program as the water flow intensity during the execution of the heating operation; and wherein the first water flow intensity of the heating program is less than the second water flow intensity of the soaking program.

[0011] In the preferred technical solution of the control method, the step of selectively determining the target heating time or the target soaking time as the total running time according to the determination result further comprises: in the case where the determination that the target heating time is greater than the target soaking time belongs to the second preset type, obtaining the material of the clothes; determining whether the clothes can withstand the target washing temperature according to the material; if the clothes can withstand the target washing temperature, determining the target heating time as the total running time; and / or if the clothes cannot withstand the target washing temperature, determining the target soaking time as the total running time; and the step of executing the heating program and the soaking program according to the total running time further comprises: in the case where the target heating time is determined as the total running time, executing the heating program and the soaking program according to the target heating time; and / or in the case where the target soaking time is determined as the total running time, executing the heating program and the soaking program according to the target soaking time.

[0012] In the preferred technical solution of the control method, the control method further comprises: during the execution of the heating program and the soaking program according to the target heating time, taking the first water flow intensity of the heating program as the water flow intensity during the execution of the heating program and the soaking program; and / or during the execution of the heating program and the soaking program according to the target soaking time, taking the first water flow intensity of the heating program as the water flow intensity during the execution of the heating program and the soaking program.

[0013] In the preferred technical solution of the control method, the step of "selectively determining the target heating time or the target soaking time as the total running time of the heating program and the soaking program according to the comparison result" further comprises: if the target heating time is less than or equal to the target soaking time, determining the target soaking time as the total running time of the heating program and the soaking program; and the step of "executing the heating program and the soaking program according to the total running time" further comprises: executing the heating program and the soaking program according to the target soaking time.

[0014] In the preferred technical solution of the control method, the control method further comprises: during the execution of the heating program and the soaking program according to the target soaking time, taking the first water flow intensity of the heating program as the water flow intensity in a first preset time period, and taking the second water flow intensity of the soaking program as the water flow intensity in a second preset time period; and the sum of the first preset time period and the second preset time period is equal to the target soaking time.

[0016] Compared with the prior art in which the washing machine respectively runs the heating program of the target heating time and the soaking program of the target soaking time, the present application selectively determines the target heating time or the target soaking time as the total running time of the heating program and the soaking program according to the comparison result of the target heating time and the target soaking time, that is, the heating program and the soaking program can be simultaneously run during the execution of the heating program and the soaking program, and only the target heating time or the target soaking time is needed, which greatly shortens the total running time of the execution of the heating program and the soaking program, and achieves the purpose of providing the shortest total running time of the heating program and the soaking program for the current running of the washing machine, thereby improving the user experience.

[0017] Further, in the case that the target heating time is greater than the target soaking time, it is possible that the target washing water level is high, and a large amount of washing water needs to be heated to the target washing temperature, so a longer time is needed, or it is possible that the target washing temperature is high, and the washing water needs to be heated to the higher target washing temperature, so a longer time is needed. In the process of executing the heating program and the soaking program, the total running time needed is different due to different reasons for the longer target heating time. In order to more accurately determine the total running time of the heating program and the soaking program, the target heating time is greater than the target soaking time is determined according to the target washing water level and the target washing temperature, and the target heating time or the target soaking time is selectively determined as the total running time according to the determination result, which not only shortens the total running time of the heating program and the soaking program, but also avoids damage to the clothes, and further improves the user experience.

[0018] Further, in the case that the target heating time is less than or equal to the target soaking time, it is indicated that the target washing water level is low, and a small amount of washing water needs to be heated to the target washing temperature, so a shorter time is needed, or the target washing temperature is low, and the washing water needs to be heated to the lower target washing temperature, so a shorter time is needed. If the heating program and the soaking program are executed according to the target heating time, the use requirement of soaking cannot be met. In order to meet the use requirements of both heating and soaking, the target soaking time is determined as the total running time of the heating program and the soaking program.

[0029] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application. For example, although the present application is described in conjunction with a washing machine, the technical solution of the present application is not limited thereto, and the control method can obviously be applied to other washing devices such as a washer-dryer, and such changes do not deviate from the principles and scope of the present application.

[0030] It should be noted that in the description of the present application, the terms "first", "second", "third", "fourth" and the like are only for descriptive purposes and should not be understood as indicating or implying relative importance.

[0031] Based on the technical problems proposed in the background art, the present application provides a control method for a washing machine, which aims to selectively determine a target heating time or a target soaking time as a total running time of a heating program and a soaking program according to a comparison result of the target heating time and the target soaking time, that is, the heating program and the soaking program can be run simultaneously in the process of executing the heating program and the soaking program, and only the target heating time or the target soaking time is run, which greatly shortens the total running time of the heating program and the soaking program, achieves the purpose of providing the shortest total running time of the heating program and the soaking program for the current operation of the washing machine, and further improves the user experience.

[0032] Firstly, referring to Figure 1 , the control method of the present application is described. Among them, Figure 1 is a main flowchart of the control method of the present application.

[0033] As Figure 1 shown, the control method of the present application includes the following steps:

[0034] S100, in the case that the washing machine is simultaneously set with a heating program and a soaking program, a target heating time is acquired;

[0035] S200, obtaining a target soaking time;

[0036] S300, comparing the target heating time and the target soaking time;

[0037] S400, selectively determining the target heating time or the target soaking time as a total running time of the heating program and the soaking program according to a comparison result;

[0038] S500, executing the heating program and the soaking program according to the total running time.

[0039] The target soaking time can be a soaking time recommended by the washing machine, a soaking time set by the user, or a soaking time corresponding to a washing program selected by the user.

[0040] It should be noted that the execution order of steps S100 and S200 in the above process is not limited to the order listed above. Step S200 can be executed first, followed by step S100, or steps S100 and S200 can be executed simultaneously, and the present application does not limit this.

[0041] The control method for obtaining the target heating time of the present application will be described below. Figure 2 The control method for obtaining the target heating time of the present application will be described below. Figure 2 is a flowchart of the control method for obtaining the target heating time of the present application.

[0042] As shown in Figure 2 , the step of "obtaining a target heating time" in step S100 specifically includes:

[0043] S111, obtaining a target washing temperature;

[0044] S112, obtaining a weight of the laundry;

[0045] S113, determining a preset weight range in which the weight is located according to the weight;

[0046] S114, determining a target washing water level according to the preset weight range;

[0047] S115, determining a target heating time according to the target washing water level and the target washing temperature.

[0048] The target washing temperature can be a washing temperature recommended by the washing machine, a washing temperature set by the user, or a washing temperature corresponding to a washing program selected by the user.

[0049] Preferably, the washing machine comprises a weight sensor for detecting the weight of the laundry, a driving motor for driving the impeller to rotate through a clutch, or for driving the inner tub to rotate and synchronously driving the impeller to rotate through the clutch, and the inner tub and the impeller have the same rotating speed.

[0050] In step S112, the weight of the laundry can be detected by the washing machine, for example, by the weight sensor in a weighing manner; or, the driving motor is rotated to a certain rotating speed and then stopped, and the weight of the laundry is calculated by reading the number of back electromotive force pulses generated by the driving motor. Of course, the weight of the laundry can also be manually input by the user, as long as the weight of the laundry can be obtained.

[0051] Preferably, the washing machine comprises four preset weight ranges, and the four preset weight ranges correspond to different target washing water levels, for example, the first preset weight range is 0kg-1kg, and the corresponding target washing water level is the second water level; the second preset weight range is 1kg-2kg, and the corresponding target washing water level is the fourth water level; the third preset weight range is 2kg-3kg, and the corresponding target washing water level is the sixth water level; the fourth preset weight range is 3kg-4kg, and the corresponding target washing water level is the eighth water level. Of course, the number of preset weight ranges, the division method of the preset weight ranges, and the corresponding target washing water level of the washing machine are not limited to the above-mentioned cases, and the weight range can also be divided into three ranges, for example, the first preset weight range is 0kg-2kg, and the corresponding target washing water level is the fourth water level; the second preset weight range is 2kg-4kg, and the corresponding target washing water level is the eighth water level. Those skilled in the art can flexibly adjust and set the number of preset weight ranges, the division method of the preset weight ranges, and the corresponding target washing water level according to the rated load capacity and accuracy requirements of the washing machine in actual application.

[0052] In steps S113 and S114, if the weight of the laundry is 1.5kg, the weight of the laundry is in the second preset weight range, and accordingly the corresponding target washing water level is the fourth water level; for example, the weight of the laundry is 3.5kg, the weight of the laundry is in the fourth preset weight range, and accordingly the corresponding target washing water level is the eighth water level, that is, according to the weight of the laundry, the preset weight range in which the weight is located can be determined, and accordingly the target washing water level can be determined according to the preset weight range.

[0053] If the target washing water level is the fourth water level and the target washing temperature is 50℃, and the heating power of the heating module of the washing machine is constant, then the target heating time for heating the washing water at the fourth water level to 50℃ can be determined, for example, 5 min; for example, if the target washing water level is the sixth water level and the target washing temperature is 40℃, and the heating power of the heating module of the washing machine is constant, then the target heating time for heating the washing water at the sixth water level to 40℃ can be determined, for example, 4.5 min.

[0054] It should be noted that in the above process, the execution order of steps S111 and S112 is not limited to the order listed above. Step S112 can be executed first, followed by step S111, or steps S111 and S112 can be executed simultaneously, and the present application does not make any limitation in this regard.

[0055] In addition, the way to obtain the target heating time is not limited to the way listed above, and other ways can also be used to determine the target heating time, for example, the target heating time can be the recommended heating time of the washing machine, or the user can set the heating time. No matter what kind of way is adopted, as long as the target heating time can be determined.

[0056] The following refers to Figures 3 to 7 The control method of the present application for selectively determining the target heating time or the target soaking time as the total running time of the heating program and the soaking program is described. Among them, Figure 3 is the first flowchart of the control method of the present application for selectively determining the target heating time or the target soaking time as the total running time; Figure 4 is the flowchart of the control method of the present application for determining the preset type to which the case that the target heating time is greater than the target soaking time belongs; Figure 5 is the second flowchart of the control method of the present application for selectively determining the target heating time or the target soaking time as the total running time; Figure 6 is the flowchart of the control method of the present application for executing the heating program and the soaking program according to the target soaking time; Figure 7 is the third flowchart of the control method of the present application for selectively determining the target heating time or the target soaking time as the total running time.

[0057] As Figure 3 shown, the step of "selectively determining the target heating time or the target soaking time as the total running time of the heating program and the soaking program according to the comparison result" in step S400 specifically includes:

[0058] S411, if the target heating time is greater than the target soaking time, the target washing water level is obtained;

[0059] S412, the target washing temperature is obtained;

[0060] S413. Based on the target washing water level and target washing temperature, determine the preset type to which the target heating time is greater than the target soaking time belongs;

[0061] S414. Based on the judgment result, the target heating time or target soaking time may be selectively determined as the total running time.

[0062] In step S411, if the target heating time is greater than the target soaking time (e.g., the target soaking time is 16 min and the target heating time is 20 min, both exceeding the target soaking time); or the target soaking time is 15 min and the target heating time is 18 min, both exceeding the target soaking time, etc.), to determine the cause of the longer target heating time, the target washing water level and target washing temperature are obtained, and the target heating time or target soaking time is selectively determined as the total running time based on the target washing water level and target washing temperature.

[0063] Furthermore, the target washing water level obtained in step S411 is the same as the target washing water level determined in step S114. Therefore, it is also possible to execute only step S411 or step S114 and use the detection result of step S411 or step S114 as the detection result of step S114 or step S411.

[0064] The target washing temperature obtained in step S412 is the same as the target washing temperature obtained in step S111. Therefore, only step S412 or step S111 can be executed, and the detection result of step S412 or step S111 can be used as the detection result of step S111 or step S412.

[0065] The preset types include a first preset type and a second preset type. The first preset type indicates a higher target washing water level and a larger volume of washing water, requiring a longer time to heat the large amount of water to the target washing temperature. The second preset type indicates a higher target washing temperature, therefore requiring a longer time to heat the washing water to the higher target washing temperature. It should be noted that the above-described classification and number of preset types are merely illustrative and not restrictive. Preset types may also include situations where both the target washing water level and the target washing temperature are high. Those skilled in the art can flexibly select the classification and number of preset types according to actual usage needs in practical applications.

[0066] like Figure 4 As shown, step S413, "determining the preset type of the case where the target heating time is greater than the target soaking time based on the target washing water level and the target washing temperature," specifically includes:

[0067] S421. determining whether the target washing water level is greater than a first preset water level and whether the target washing temperature is greater than a preset temperature;

[0068] If the target washing water level is greater than the first preset water level and the target washing temperature is less than or equal to the preset temperature, step S422 is performed.

[0069] If the target washing temperature is greater than the preset temperature, step S423 is performed.

[0070] S422. determining that the case where the target heating time is greater than the target soaking time belongs to the first preset type.

[0071] S423. determining that the case where the target heating time is greater than the target soaking time belongs to the second preset type.

[0072] In step S422, if the target washing water level is greater than the first preset water level and the target washing temperature is less than or equal to the preset temperature, for example, the first preset water level is the sixth water level, and the target washing water level is the eighth water level, which is greater than the first preset water level, indicating that the target washing water level is high, and a large amount of washing water is needed to heat the washing water to the target washing temperature. The time required is longer. Moreover, the preset temperature is 45℃, and the target washing temperature is 40℃, which is less than the preset temperature, and the target washing temperature is low. The time required to heat the washing water to a lower target washing temperature is shorter, so it can be determined that only because the target washing water level is high, the target heating time is greater than the target soaking time. The case belongs to the first preset type.

[0073] In step S423, if the target washing temperature is greater than the preset temperature, for example, the preset temperature is 45℃, and the target washing temperature is 50℃, which is greater than the preset temperature, indicating that the target washing temperature is high. The time required to heat the washing water to a higher target washing temperature is longer. Since the target washing temperature is high, the higher target washing temperature may cause damage to the clothes. In order to avoid damage to the clothes, whether the target washing water level is high or low, the case where the target heating time is greater than the target soaking time is determined to belong to the second preset type.

[0074] As shown in FIG. 4B, the step of “determining the target heating time or the target soaking time as the total running time according to the determination result” in step S414 specifically includes: Figure 5

[0075] S431. determining the target soaking time as the total running time in the case where the case where the target heating time is greater than the target soaking time belongs to the first preset type.

[0076] ​In step S431, in the case where it is determined that the target heating time is greater than the target soaking time and the case belongs to the first preset type, it is considered that the target washing temperature is low, for example, 40℃, and the washing at this temperature will not cause damage to any material of clothes. However, it is also considered that the target heating time is long due to the high target washing water level, and the target washing temperature is low. Even if the heating time is shortened to make the washing temperature slightly lower, for example, to 35℃, the washing effect will not be significantly affected. In order to shorten the total running time of the heating program and the soaking program, the target soaking time less than the target heating time is determined as the total running time.

[0077] With reference to Figure 5 , in step S500, the step of "executing the heating program and the soaking program according to the total running time" specifically includes:

[0078] S511, executing the heating program and the soaking program according to the target soaking time.

[0079] As shown in Figure 6 , in step S511, the step of "executing the heating program and the soaking program according to the target soaking time" specifically includes:

[0080] S521, controlling the washing machine to inject water to a second preset water level;

[0081] S522, after the washing machine injects water to the second preset water level, controlling the washing machine to execute a heating operation and starting to count an actual heating time;

[0082] S523, after the washing water is heated to the target washing temperature, controlling the washing machine to continue to inject water to the target washing water level;

[0083] S524, in the process of controlling the washing machine to continue to inject water to the target washing water level, controlling the washing machine to continue to execute the heating operation and continue to count the actual heating time until the counted actual heating time reaches the target soaking time;

[0084] The second preset water level is less than the target washing water level; further, the second preset water level is less than the first preset water level. Of course, the second preset water level can also be greater than or equal to the first preset water level, and the relationship between the first preset water level and the second preset water level can be flexibly adjusted and set by those skilled in the art.

[0085] Hereinafter, the second preset water level is taken as the third water level, the target washing water level is taken as the eighth water level, and the target washing temperature is taken as 40℃ as an example for further description.

[0086] Firstly, the washing machine is controlled to fill water to the third water level, and after the water level reaches the third water level, the washing machine is controlled to perform a heating operation and start counting the actual heating time. Compared with directly heating the washing water at the eighth water level to 40℃, the water level to be heated is reduced, so that the washing water can be quickly heated to 40℃, the target heating time is shortened, and in the case that the detergent has been put, the detergent can be quickly dissolved to form a high-concentration washing liquid in the washing water at the third water level, so that the clothes can be soaked at a high concentration, and the soaking effect is improved, so that the clothes can be washed more cleanly.

[0087] Further, in the process of "controlling the washing machine to perform the heating operation", since the heating operation is performed, in order to better meet the user's demand for the heating program, the first water flow intensity of the heating program is taken as the water flow intensity when the heating operation is performed.

[0088] Secondly, after the washing water is heated to 40℃, the washing machine is controlled to continue to fill water to the eighth water level, and in the process of continuing to fill water, the washing machine is controlled to continue to perform the heating operation, that is, to heat while filling water, so as to shorten the total time of filling water and heating, thereby further shortening the total running time of the heating program and the soaking program; and the heating method of heating while filling water can quickly heat the newly filled washing water to 40℃, so that when the actual heating time reaches the target soaking time, the washing water at the eighth water level can be heated to the range of 40℃, thereby shortening the time of heating the washing water at the eighth water level to 40℃, and further shortening the total running time of the heating program and the soaking program.

[0089] Further, in the process of continuing to fill water, the concentration of the detergent is gradually diluted, and gradually forms a medium-concentration washing liquid and a low-concentration washing liquid, until the concentration of the detergent reaches the target concentration, so that the clothes are soaked at a variable concentration from high concentration to low concentration, and under the soaking of washing liquids at different concentrations, the soaking effect is further improved, and the clothes can be washed more cleanly and completely.

[0090] Further, in the process of "controlling the washing machine to continue to fill water to the eighth water level (i.e. the target washing water level)", since the water is filled while being heated, the heating operation is still performed, and in order to better meet the user's demand for the heating program, the first water flow intensity of the heating program is taken as the water flow intensity when the heating operation is performed.

[0091] Further, in the process of "controlling the washing machine to continue to execute the heating operation after the washing machine continues to fill water to the eighth water level (i.e. the target washing water level)", although the heating operation is still being executed, at this time, the water has been filled to the eighth water level, the water level is high, the newly filled washing water and the washing water that has been filled and mixed are not uniform enough, and since the second water flow intensity of the soaking program is greater than the first water flow intensity of the heating program, the second water flow intensity of the soaking program is taken as the water flow intensity when the heating operation is executed, thereby increasing the water flow intensity, and under the action of the second water flow intensity, the washing water can be mixed uniformly, the washing water temperature is uniformly distributed, and the washing water can be quickly heated to 40℃.

[0092] It should be noted that in step S524, the washing machine can also be controlled to continue to execute the heating operation after the washing machine continues to fill water to the target washing water level; correspondingly, when the washing water is heated to the target washing temperature, the washing machine is controlled to stop counting the actual heating time, and the actual heating time is counted again when the washing machine continues to execute the heating operation, until the total actual heating time reaches the target soaking time.

[0093] As shown in FIG. 4, the step of "selectively determining the target heating time or the target soaking time as the total running time according to the judgment result" in step S414 specifically includes: Figure 7

[0094] S441, in a case where the target heating time is greater than the target soaking time and the case belongs to the second preset type, obtaining the material of the laundry;

[0095] S442, judging whether the laundry can withstand the target washing temperature according to the material; if yes, executing step S443; if no, executing step S444;

[0096] S443, determining the target heating time as the total running time;

[0097] S444, determining the target soaking time as the total running time.

[0098] In step S441, in a case where the target heating time is greater than the target soaking time and the case belongs to the second preset type, it is indicated that the target heating time is long due to the high target washing temperature, and the high washing temperature may cause damage to the laundry made of materials such as wool, cashmere, and silk. In order to avoid the above situation, the material of the laundry is obtained, and whether the laundry can withstand the target washing temperature is judged according to the material.

[0099] ​Further, the washing machine collects images of the clothes through a camera, and an image processing program performs grayscale processing on the collected images, and compares the obtained results after processing with a preset grayscale judgment model to obtain the material information of the clothes, wherein the preset grayscale judgment model can be preset as: 60% of the grayscale value is fiber, 100% of the grayscale value is cotton and hemp, and 30% of the grayscale value is polyester, and the present application does not make any limitation on this.

[0100] Alternatively, the washing machine scans the RFID tag on the clothes through the RFID identification module, and determines the material of the clothes according to the identification result of the RFID identification module; wherein the RFID tag on the clothes contains information such as the material, color, size and washing method of the clothes.

[0101] It should be noted that the method for obtaining the material of the clothes is not limited to the two methods listed above, and the material of the clothes can also be detected by a material sensor, regardless of the method used to obtain the material of the clothes, and any one of the specific implementation methods should not limit the present application.

[0102] In steps S442 to S444, it is judged whether the clothes can withstand the target washing temperature according to the material, for example, the target washing temperature is 40℃, the detected material of the clothes is cotton, and the highest washing temperature of cotton is 50℃, which is higher than 40℃, indicating that the cotton clothes can withstand the washing temperature of 40℃, in this case, if the washing machine performs the heating operation according to the target heating time to raise the temperature of the washing water to 40℃, it will not cause damage to the clothes, and at the same time, the clothes are soaked during the heating process, and the actual soaking time is greater than the target soaking time, which not only meets the requirements of heating and soaking at the same time, but also avoids damage to the clothes, therefore, the target heating time is determined as the total running time.

[0103] For example, the target washing temperature is 40℃, the detected material of the clothes is wool, and the highest washing temperature of wool is 30℃, which is lower than 40℃, indicating that the wool clothes cannot withstand the washing temperature of 40℃, if the clothes are washed at a temperature of 40℃, the wool material will be damaged, in order to avoid the above situation, the target soaking time less than the target heating time is determined as the total running time, so as to shorten the heating time, so that the actual washing temperature does not reach the target washing temperature, thereby reducing the actual washing temperature and avoiding damage to the clothes.

[0104] Continuing to refer to Figure 7 , in step S500, the step of "executing the heating program and the soaking program according to the total running time" further includes:

[0105] S512, in the case where the target heating time is determined as the total running time, the heating program and the soaking program are executed according to the target heating time;

[0106] S513, in the case that the target soaking time is determined as the total running time, performing the heating program and the soaking program according to the target soaking time.

[0107] The following further illustrates the specific execution manners of steps S512 and S513 by taking the target soaking time as 16 min and the target heating time as 20 min as an example.

[0108] In step S512, when starting to perform the heating program and the soaking program, the heating operation and the soaking operation are simultaneously performed until the total time of performing the heating program and the soaking program reaches 20 min.

[0109] In step S513, when starting to perform the heating program and the soaking program, the heating operation and the soaking operation are simultaneously performed until the total time of performing the heating program and the soaking program reaches 16 min.

[0110] Further, in step S512, in the process of "performing the heating program and the soaking program according to the target heating time", since the target heating time determined in step S411 is greater than the target soaking time, it can be considered that the soaking operation is accompanied by the heating operation, and in order to better meet the user's demand for the heating program, the first water flow intensity of the heating program is taken as the water flow intensity when performing the heating program and the soaking program.

[0111] Further, in step S513, in the process of "performing the heating program and the soaking program according to the target soaking time", since the target soaking time determined in step S411 is less than the target heating time, it can be considered that the heating operation is performed while the soaking operation is performed, and in order to better meet the user's demand for the heating program, the first water flow intensity of the heating program is taken as the water flow intensity when performing the heating program and the soaking program.

[0112] It should be noted that the above-mentioned target heating time, target soaking time, first preset water level, second preset water level, target washing water level, preset temperature, target washing temperature, material of the clothes and the highest washing temperature corresponding to the material of the clothes are only exemplary and are not limited, and those skilled in the art can flexibly adjust and set the target heating time, target soaking time, first preset water level, second preset water level, target washing water level, preset temperature, target washing temperature, material of the clothes and the highest washing temperature corresponding to the material of the clothes according to the use demand in actual application.

[0113] It should be further noted that the execution sequence of steps S411 to S412 in the above process is not limited to the above-mentioned sequence, and step S412 can be executed first and then step S411, or steps S411 and S412 can be executed simultaneously, and the present application does not make any limitation on this. The execution sequence of "judging whether the target washing water level is greater than the first preset water level" and "judging whether the target washing temperature is greater than the preset temperature" in step S421 is not limited to the above-mentioned sequence, and "judging whether the target washing water level is greater than the first preset water level" can be executed first and then "judging whether the target washing temperature is greater than the preset temperature", or "judging whether the target washing temperature is greater than the preset temperature" can be executed first and then "judging whether the target washing water level is greater than the first preset water level", and the present application does not make any limitation on this. Steps S422 and S423 have no sequence and are parallel, and are only related to the judgment results of whether the target washing water level is greater than the first preset water level and whether the target washing temperature is greater than the preset temperature, and corresponding steps can be executed according to different judgment results. Steps S431 and S441 have no sequence and are parallel, and are only related to the judgment result of which preset type the case that the target heating time is greater than the target soaking time belongs to, and corresponding steps can be executed according to different judgment results. Steps S443 to S444 have no sequence and are parallel, and are only related to the judgment result of whether the clothes can withstand the target washing temperature, and corresponding steps can be executed according to different judgment results.

[0114] The control method for selectively determining the target heating time or the target soaking time as the total running time of the heating program and the soaking program of the present application will be further described below with reference to Figure 8 The control method for selectively determining the target heating time or the target soaking time as the total running time of the present application is further described. Among them, Figure 8 is the fourth flow chart of the control method for selectively determining the target heating time or the target soaking time as the total running time of the present application.

[0115] As shown in Figure 8 , the step of "selectively determining the target heating time or the target soaking time as the total running time of the heating program and the soaking program according to the comparison result" in step S400 further includes:

[0116] S415, if the target heating time is less than or equal to the target soaking time, the target soaking time is determined as the total running time of the heating program and the soaking program.

[0117] In step S415, if the target heating time is less than or equal to the target soaking time, for example, the target soaking time obtained is 15 min, and the target heating time obtained is 10 min, which is less than the target soaking time; or the target soaking time obtained is 20 min, and the target heating time obtained is 17 min, which is less than the target soaking time. It indicates that the target washing water level is low, and the washing water is less. The time required for heating a small amount of washing water to the target washing temperature is short, or the target washing temperature is low, and the time required for heating the washing water to a lower target washing temperature is short. If the heating program and the soaking program are executed according to the target heating time, the use requirement of soaking cannot be met. In order to meet the use requirements of heating and soaking at the same time, the target soaking time is determined as the total running time of the heating program and the soaking program.

[0118] With reference to Figure 8 , in step S500, the step of "executing the heating program and the soaking program according to the total running time" further includes:

[0119] S514, executing the heating program and the soaking program according to the target soaking time.

[0120] Next, taking the target soaking time of 15 min and the target heating time of 10 min as an example, the specific execution mode of step S514 is further described.

[0121] When starting to execute the heating program and the soaking program, the heating operation and the soaking operation are simultaneously executed. After executing the heating operation for 10 min, the heating operation is stopped, and the soaking operation is continued to be executed until the total time of the heating program and the soaking program reaches 15 min.

[0122] Further, in the above process of executing the heating program and the soaking program, since the heating operation and the soaking operation are simultaneously executed in the first preset time period of 10 min (i.e., the first preset time period), in order to better meet the user's requirement for the heating program, the first water flow intensity of the heating program is taken as the water flow intensity in the first preset time period. After 10 min, i.e., between 10 min and 15 min (i.e., the second preset time period), only the soaking operation is executed. In order to better meet the user's requirement for the soaking program, the second water flow intensity of the soaking program is taken as the water flow intensity in the second preset time period. The sum of the first preset time period and the second preset time period is equal to the target soaking time, and the first preset time period is earlier than the second preset time period.

[0123] Alternatively, in an alternative embodiment, when starting to execute the heating program and the soaking program, only the soaking operation is executed, and the heating operation is not executed. After executing the soaking operation for 5 min, the heating operation is started to be executed, and the soaking operation is continued to be executed until the total time of the heating program and the soaking program reaches 15 min.

[0124] Further, in the process of executing the heating program and the soaking program, since only the soaking operation is executed within the first 5 minutes (i.e. the second preset time period), in order to better meet the user's demand for the soaking program, the second water flow intensity of the soaking program is taken as the water flow intensity within the second preset time period; while after 5 minutes, i.e. between 5 minutes and 15 minutes (i.e. the first preset time period), the heating operation and the soaking operation are executed simultaneously, in order to better meet the user's demand for the heating program, the first water flow intensity of the heating program is taken as the water flow intensity within the first preset time period, wherein the sum of the first preset time period and the second preset time period is equal to the target soaking time, and the first preset time period is later than the second preset time period.

[0125] It should be noted that the above-mentioned target heating time, target soaking time, first preset time period and second preset time period are exemplary and are not limited, and those skilled in the art can flexibly adjust and set the target heating time, target soaking time, first preset time period and second preset time period according to the use demand in actual application.

[0126] It should be further noted that in the above process, steps S411 and S415 have no sequence and are parallel, and are only related to the judgment result of whether the target heating time is greater than the target soaking time, and the corresponding steps can be executed according to different judgment results and comparison results.
