[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe this application in detail with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

[0053] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.

[0054] In the following description, the terms "first / second / third" are only used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence when allowed, so that the embodiments of this application described here can be implemented in an order other than that illustrated or described here.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0056] The following refers to Figures 1 to 10 to describe a control method, device, household appliance, and computer-readable storage medium provided according to some embodiments of this application.

[0057] An embodiment of the first aspect of this application provides a control method, which includes Figure 1 the steps S101 to S104 shown below. The following will explain each step in combination with Figure 1 this.

[0058] Step S101: Determine to enter the steam generation stage and obtain the historical operation data of the steam generator.

[0059] The control method of the embodiments of this application is applied to household appliances with a steam generator. The household appliances can be devices with a steam function such as a washer-dryer, dryer, dry cleaner, dishwasher, clothes steamer, and garment care machine. In the embodiments of this application, a household appliance with a steam generator is taken as an example of a dryer for explanation. Unless otherwise specified below, the household appliance refers to a dryer.

[0060] The user puts the clothes to be processed into the drum of the dryer and selects a drying program. The drying programs of the dryer at least include drying programs with a steam function, such as drying programs for cotton and linen, wool, and down jackets; drying programs without a steam function, such as drying programs for underwear, sportswear, and baby clothes; and a steam care program. Among them, the operation duration of the steam generator for the drying programs with a steam function and the steam care program is the factory-set value. In the embodiments of the present application, based on the drying program with a steam function or the steam care program selected by the user, the operation duration for the steam generator to generate steam this time is determined. When determining this operation duration, the historical operation data of the steam generator is first obtained.

[0061] In one implementation manner of the embodiments of the present application, the historical operation data may include the historical operation times. The historical operation times are the cumulative number of times of entering the steam generation stage, that is, the cumulative number of times of using the steam generator to generate steam. Here, the historical operation times are denoted as N, where N is a natural number.

[0062] In another implementation manner of the embodiments of the present application, the historical operation data may include the historical operation duration. The historical operation duration is the cumulative duration of using the steam function, that is, the cumulative duration of using the steam generator to generate steam. Here, the historical operation duration is denoted as T, where T is a natural number.

[0063] In yet another implementation manner of the embodiments of the present application, the historical operation data may include the historical operation times and the historical operation duration, that is, the cumulative number of times and the duration of using the steam generator to generate steam are obtained simultaneously.

[0064] Step S102, obtain the default operation duration of the steam generator.

[0065] Here, the default operation duration refers to the duration for which the steam generator defaults to operate in the steam generation stage, that is, when the dryer operates a drying program with a steam function or a steam care program, the duration for which the steam generator generates steam. In the embodiments of the present application, the default operation duration may be the default value set at the factory. Here, the default operation duration t may be set to any value between 8 minutes (min) and 15 min, such as 10 min.

[0066] Step S103, determine that the historical operation data reaches a first data threshold, and adjust the default operation duration according to the historical operation data to obtain the adjusted operation duration.

[0067] During each operation of the steam generator, when the heating tubes in the steam generator heat water to boiling to vaporize it and produce steam, calcium sulfate, which is slightly soluble in water, will precipitate due to the vaporization of water. The carbonate ions in the water will combine with calcium, magnesium and other ions to form calcium carbonate and magnesium carbonate, which are insoluble in water, that is, water scale. As the water continuously vaporizes, the water scale content increases continuously. After reaching saturation, water scale is formed and adheres to the heating tubes. As the service life or the number of uses of the steam generator increases, the water scale adhering to the heating tubes will accumulate more and more, and finally form a thick layer of water scale. Since the heat conduction ability of the water scale is extremely poor, the amount of steam generated by the steam generator per unit time is reduced.

[0068] In the related art, the operation duration of the steam generator is fixed each time it enters the steam generation stage. Each time the dryer operates a drying program or a steam care program with a steam function, the steam generator is controlled to operate for a default operation duration. The operation duration remains unchanged. However, due to the influence of the water scale on the heating tubes, the amount of steam generated by the steam generator per unit time is reduced, resulting in a reduction in the amount of steam generated during the steam generation stage, which affects the drying, sterilization, deodorization, wrinkle removal and other treatment effects of the clothes. To solve this problem, the operation duration of the steam generator can be adjusted according to the amount of water scale adhering to the heating tubes, so that the dryer can achieve the use effect without water scale as much as possible when there is water scale. However, during the steam generation stage of the steam generator, water is continuously introduced and steam is continuously generated. It is impossible to determine the amount of water scale in the heating tubes by the amount of water introduced or the amount of steam generated. And it is obviously unrealistic to disassemble and weigh the heating tubes in the steam generator before each use of the dryer. Based on this, in the embodiments of the present application, the operation duration of the steam generator is adjusted based on the historical operation data of the steam generator.

[0069] In the embodiments of the present application, the historical operation data of the steam generator is obtained according to step S101, and it is judged whether the historical operation data reaches a first data threshold. When the historical operation data reaches the first data threshold, it is considered that the water scale on the heating tubes will have a non-negligible impact on the steam generator. At this time, the default operation duration of the steam generator is adjusted according to the historical operation data to obtain the adjusted operation duration.

[0070] In the embodiments of the present application, due to the influence of water scale, the heating efficiency of the heating tubes is reduced. The adjusted operation duration is set to be greater than the default operation duration. By extending the operation duration of the steam generator, the amount of steam generated by the steam generator during the steam generation stage is not reduced as much as possible, so that the clothes can achieve treatment effects such as drying, sterilization, deodorization, and wrinkle removal.

[0071] In implementation, if the historical operation data includes the historical operation times N, the longer the operation times of the steam generator, the more scale in the heating tubes of the steam generator. Therefore, it is possible to determine whether to adjust the default operation duration of the steam generator according to the historical operation times of the steam generator. Here, the first data threshold N1 can be set to any integer value between 40 and 60 times, such as 50 times. When the historical operation times N reaches the first data threshold N1, that is, N≥50 times, the default operation duration t is adjusted according to the historical operation times N. The larger the historical operation times N, the longer the default operation duration is adjusted to, and the adjusted operation duration is obtained.

[0072] In implementation, if the historical operation data includes the historical operation duration T, the longer the operation duration of the steam generator, the more scale in the heating tubes of the steam generator. Therefore, it is also possible to determine whether to adjust the default operation duration of the steam generator according to the historical operation duration of the steam generator. Here, the first data threshold T1 can be set to any value between 400 min and 600 min, such as 500 min. When the historical operation duration T reaches the first data threshold T1, that is, T≥500 min, the default operation duration t is adjusted according to the historical operation duration T. The longer the historical operation duration T, the longer the default operation duration is adjusted to, and the adjusted operation duration is obtained.

[0073] Step S104, control the steam generator to operate for the adjusted operation duration to determine the end of the steam generation stage.

[0074] Adjust the default operation duration according to the historical operation times or historical operation duration. After obtaining the adjusted operation duration, control the steam generator to operate for the adjusted operation duration in this steam generation stage, so that the operation duration of the steam generator is no longer a fixed value, realizing flexible control of the household appliance to generate steam and meeting the diverse needs of users; the adjusted operation duration is greater than the default operation duration, so that the steam generator operates for a longer time in the steam generation stage, keeping the amount of steam generated in the steam generation stage unchanged, and ensuring the treatment effects such as clothes drying, sterilization, deodorization, and wrinkle removal.

[0075] The control method provided by the embodiment of the present application is applied to a household appliance with a steam generator. The method includes: determining to enter the steam generation stage, obtaining the historical operation data of the steam generator, where the historical operation data includes the historical operation times and / or the historical operation duration; obtaining the default operation duration of the steam generator; determining that the historical operation data reaches a first data threshold, adjusting the default operation duration according to the historical operation data to obtain an adjusted operation duration; controlling the steam generator to operate for the adjusted operation duration, and determining to end the steam generation stage. By adjusting the operation duration of the steam generator according to the historical operation data, the operation duration of the steam generator is no longer a fixed value, realizing flexible control of the household appliance to generate steam and meeting the diverse needs of users; by adjusting the operation duration of the steam generator, it is ensured that the household appliance achieves treatment effects such as drying, sterilization, deodorization, and wrinkle removal.

[0076] In Figure 1 In the illustrated embodiment, as the number of operations of the steam generator increases or the operation duration becomes longer, the scale attached to the heating tube will become thicker. If the amount of scale reaches a certain level, the excessive scale will cause a significant reduction in the efficiency of the steam generator, and the scale thickness attached to different positions on the heating tube is uneven, and uneven heating easily causes local overheating and burnout of the heating tube, and even leads to an explosion accident. In the embodiment of the present application, when the amount of scale on the heating tube reaches a certain value, the supply of hard water to the heating tube is stopped to avoid the continuous formation of scale, and thus avoid the formation of excessive scale on the heating tube and the existence of potential safety hazards. After the above step S103, the control method may further include steps S201 to S202:

[0077] Step S201, determining that the historical operation data reaches a second data threshold, determining to start the soft water supply program, and controlling the conveying device to convey soft water to the steam generator.

[0078] Here, the second data threshold is greater than the first data threshold.

[0079] When the historical operation data reaches the first data threshold, it is considered that the scale attached to the heating tube will have a non-negligible impact on the steam generator. After that, the steam generator is controlled to generate steam for the adjusted operation duration determined based on the historical operation data.

[0080] When the steam generator enters the steam generation stage again, new historical operation data is obtained, and it is determined whether the new historical operation data reaches the second data threshold. When the new historical operation data does not reach the second data threshold, return to step S103 to continue accumulating the historical operation data of the steam generator.

[0081] When the new historical operation data reaches the second data threshold, it is considered that the amount of scale attached to the heating pipe reaches the upper limit value. If the amount of scale continues to increase, it will cause a safety accident. At this time, stop continuously feeding hard water containing more soluble calcium and magnesium compounds into the steam generator, start the soft water program, and feed soft water obtained after softening treatment, which contains no or less soluble calcium and magnesium compounds, into the steam generator. The heating pipe heats the soft water, and no more scale will be generated. On the premise of ensuring safety, continue to use the steam generator to generate steam.

[0082] Step S202: Adjust the default operation duration according to the second data threshold to obtain the adjusted operation duration.

[0083] After the soft water program is started, the water fed into the heating pipe is soft water, and no more scale will be generated thereafter. Therefore, the default operation duration can be adjusted based on the second data threshold to obtain the adjusted operation duration.

[0084] In one implementation, "adjust the default operation duration according to the second data threshold" can be implemented as: obtain the difference between the second data threshold and the first data threshold, determine the adjustment value for adjusting the default operation duration according to the difference and the first data threshold, and adjust the default operation duration based on the adjustment value to obtain the adjusted operation duration.

[0085] In the embodiments of the present application, when the historical operation data includes the historical operation times N, the first data threshold is denoted as N1, the second data threshold is denoted as N2, the difference between the second data threshold and the first data threshold △N = N2 - N1, and the adjustment value Determine the adjusted operation duration t' = t + Δt. Here, the first data threshold N1 can be set to any integer value between 40 and 60 times, the second data threshold N2 can be set to any integer value between 80 and 120 times, and the default operation duration t can be set to any value between 8 min and 15 min. For example, when N1 is set to 50 times, N2 is set to 100 times, and t is set to 10 min, the adjusted operation duration

[0086] When the historical operation data includes the historical operation duration T, the first data threshold is denoted as T1, the second data threshold is denoted as T2, the difference between the second data threshold and the first data threshold △T = T2 - T1, and the adjustment value Determine the adjusted operation duration \(t' = t+\Delta t\). Here, the first data threshold \(T_1\) can be set to any value between 400 min and 600 min, the second data threshold \(T_2\) can be set to any value between 800 min and 1200 min, and the default operation duration \(t\) can be set to any value between 8 min and 15 min. For example, when \(T_1\) is set to 500 min, \(T_2\) is set to 1000 min, and \(t\) is set to 10 min, the adjusted operation duration

[0087] Since \(N_1\), \(N_2\), \(T_1\), and \(T_2\) are fixed values, after the soft water program is started, the scale in the steam generator will no longer increase, and the operation duration of the steam generator entering the steam generation stage each time will no longer change.

[0088] After obtaining the adjusted operation duration, step S104 can be continued to control the steam generator to operate based on the adjusted operation duration to generate steam until the steam generation stage ends.

[0089] The control method provided by the embodiment of the present application determines whether the historical operation data reaches the second data threshold according to the historical operation times of the steam generator or according to the historical operation duration of the steam generator, so as to determine whether it is necessary to introduce soft water into the steam generator. When it is determined that soft water needs to be introduced, the soft water program is started to soften hard water into soft water, and the conveying device is controlled to convey the soft water to the steam generator. The heating tube heating the soft water will no longer generate scale, and the steam generator can continue to generate steam on the premise of ensuring safety, ensuring that the household appliance can continue to be used. After generating steam with soft water, the scale in the heating tube will no longer increase. By adjusting the operation duration of the steam generator through the second data threshold, the operation duration of the steam generator is no longer the default fixed value, realizing flexible control of the household appliance to generate steam and meeting the diverse needs of users.

[0090] In the above-described embodiment, when the operation times of the steam generator are few or the operation duration is short, the scale attached to the heating tube is less, and the steam generation efficiency of the steam generator is relatively high. At this time, there is no need to adjust the default operation duration of the steam generator. After step S102 above, the control method may further include Figure 3 Steps S301 to S302 shown below:

[0091] Step S301, determine whether the historical operation data reaches the first data threshold.

[0092] When the historical operation data of the steam generator reaches the first data threshold, that is, when the historical operation times N≥N1, or when the historical operation duration T≥T1, it indicates that the default operation duration of the steam generator needs to be adjusted, and at this time, step S103 is entered; when the historical operation data of the steam generator does not reach the first data threshold, that is, when N<N1, or T<T1, there is no need to adjust the default operation duration of the steam generator, and at this time, step S302 is entered.

[0093] Step S302, it is determined that the historical operation data does not reach the first data threshold, the steam generator is controlled to operate for the default operation duration, and it is determined to end the steam generation stage.

[0094] The control method provided by the embodiment of the present application determines whether the historical operation times of the steam generator or the historical operation duration of the steam generator reaches the first data threshold to determine whether the default operation duration of the steam generator needs to be adjusted. When it is determined that the historical operation data does not reach the first data threshold, the steam generator is controlled to operate for the default operation duration to generate steam, ensuring the normal use of household appliances.

[0095] In some embodiments, in the above Figure 1 In step S103 shown, "adjust the default operation duration according to the historical operation data to obtain the adjusted operation duration", which can be achieved through Figure 4 the steps shown:

[0096] Step S1031, obtain the difference between the historical operation data and the first data threshold.

[0097] When the historical operation data includes the historical operation times N, and the corresponding first data threshold is N1, the difference △N between the historical operation data and the first data threshold is △N = N - N1; when the historical operation data includes the historical operation duration T, and the corresponding first data threshold is T1, the difference △T between the historical operation data and the first data threshold is △T = T - T1; when the historical operation data includes the historical operation times N and the historical operation duration T, and the corresponding first data thresholds include N1 and T1, if the historical operation times N reaches the first data threshold N1, the difference between the historical operation data and the first data threshold is △N = N - N1, if the historical operation duration T reaches the first data threshold T1, the difference between the historical operation data and the first data threshold is △T = T - T1; if the historical operation times N and the historical operation duration T reach the first data thresholds N1 and T1 respectively at the same time, the difference between the historical operation data and the first data threshold can be △N or △T.

[0098] Step S1032, determine the adjustment value for adjusting the default operation duration according to the difference and the first data threshold.

[0099] Here, the adjustment value can be determined according to the change rate of the difference value and the first data threshold. The larger the change rate, the more scale deposit there is, and the larger the adjustment value. If the difference value determined according to step S1031 is ΔN, the adjustment value for adjusting the default operation duration If the difference value determined according to step S1031 is ΔT, the adjustment value for adjusting the default operation duration where t is the default operation duration of the steam generator.

[0100] As the number of times the steam generator enters the steam generation stage increases, the historical operation data N or T increases, causing the adjustment value Δt to gradually increase.

[0101] Step S1033: Adjust the default operation duration based on the adjustment value to obtain the adjusted operation duration.

[0102] Here, the sum of the adjustment value Δt determined in step S1032 and the default operation duration t is determined as the adjusted operation duration, that is, the adjusted operation duration t' = t + Δt.

[0103] Here, when the historical operation data includes the historical operation times N, the first data threshold N1 can be set to any integer value between 40 and 60 times, and the default operation duration t can be set to any value between 8 min and 15 min. For example, when N1 is set to 50 times and t is set to 10 min, the adjusted operation duration The historical operation times N satisfy N ≥ N1. For example, when the steam generator has run 60 times, the adjusted operation duration

[0104] Here, when the historical operation data includes the historical operation duration T, the first data threshold T1 can be set to any value between 400 min and 600 min, and the default operation duration t can be set to any value between 8 min and 15 min. For example, when T1 is set to 500 min and t is set to 10 min, the adjusted operation duration The historical operation duration T satisfies T ≥ T1. For example, when the steam generator has run 700 min, the adjusted operation duration

[0105] The adjustment method for the default operation duration provided in the embodiments of the present application determines different adjustment values according to different historical operation data of the steam generator, realizes the dynamic adjustment of the operation duration, makes the operation duration of the steam generator a dynamic change value, and realizes the flexible control of the steam generation of household appliances to meet the diverse needs of users.

[0106] In some embodiments, after each determination of the end of the steam generation stage, the historical operation data of the steam generator is updated, which can be achieved through Figure 5 the steps shown:

[0107] Step S501: Update the historical operation data based on the operation data in the steam generation stage to obtain the updated historical operation data.

[0108] If the operation times of the steam generator are accumulated, update the historical operation times based on the operation times in the steam generation stage to obtain the updated historical operation times. That is, after each steam generation stage ends, increment the operation times of the steam generator by 1. The updated historical operation data is the total operation times of the steam generator.

[0109] If the operation duration of the steam generator is accumulated, update the historical operation duration based on the operation duration in the steam generation stage to obtain the updated historical operation duration. That is, after each steam generation stage ends, add the operation duration of this entry into the steam generation stage to the operation duration of the steam generator. The updated historical operation data is the total operation duration of the steam generator.

[0110] Step S502: Save the updated historical operation data.

[0111] Save the updated historical operation data so as to obtain the historical operation data again when entering the steam generation stage next time.

[0112] In the embodiments of the present application, after each steam generation stage ends, update and save the historical operation data, which is convenient for reading the data when entering the steam generation stage next time.

[0113] In some embodiments, the above first data threshold and second data threshold may be default values set at the factory, or the first data threshold and second data threshold may be differentially set as default values matching the region where the dryer is located. Before the above step S103, the control method may further include Figure 6 Steps S601 to S602 shown as follows:

[0114] Step S601: Obtain the geographical location information of the household appliance.

[0115] Here, the geographical location information of the household appliance can be set by the user, or a positioning device (such as an antenna) can be set in the household appliance, and the position of the household appliance on the ground can be determined by receiving the satellite signal sent by the antenna through the Global Positioning System (GPS).

[0116] Step S602: Query the pre-stored relationship table according to the geographical location information to determine the first data threshold.

[0117] Among them, the relationship table is a data table representing the corresponding relationship between the geographical location information and the first data threshold.

[0118] In household appliances, the corresponding relationship between location information of various places and the first data threshold can be pre-stored. For example, the geographical location information of the household appliance can be "Beijing" set by the user. By querying, it can be known that the first data threshold corresponding to this geographical location information is N1. Here, the data table of the corresponding relationship between the geographical location information and the first data threshold can be the threshold pre-set according to the water hardness of each region. In regions with lower water hardness, less scale is generated each time the steam generator operates. Therefore, the first data threshold is pre-set to a larger value, and after running a relatively large number of times, the default running duration of the steam generator starts to be adjusted; in regions with higher water hardness, more scale is generated each time the steam generator operates. Therefore, the first data threshold is pre-set to a smaller value, and after running a relatively small number of times, the default running duration of the steam generator starts to be adjusted.

[0119] In some other embodiments, the household appliance can obtain more accurate geographical location information according to real-time GPS positioning. For example, it is obtained that the geographical location information of the household appliance is located in "XX Community, Sanlitun Sub-district, Chaoyang District, Beijing". When the household appliance can connect to the network, it can dynamically obtain the water hardness of this accurate location, and then set the first data threshold more suitable for the location where the household appliance is located according to the obtained water hardness.

[0120] In some other embodiments, the above step S602 can be replaced by step S602': Query the pre-stored relationship table according to the geographical location information to determine the first data threshold and the second data threshold. At this time, this relationship table is a data table representing the corresponding relationship between the geographical location information, the first data threshold, and the second data threshold. In regions with lower water hardness, less scale is generated each time the steam generator operates. Therefore, the first data threshold and the second data threshold are pre-set to larger values (where the second data threshold is greater than the first data threshold), and after running a relatively large number of times, the default running duration of the steam generator starts to be adjusted; in regions with higher water hardness, more scale is generated each time the steam generator operates. Therefore, the first data threshold and the second data threshold are pre-set to smaller values (where the second data threshold is greater than the first data threshold), and after running a relatively small number of times, the default running duration of the steam generator starts to be adjusted.

[0121] The method provided by the embodiments of the present application sets the data threshold for starting to adjust the default running duration of the steam generator according to the geographical location information of the household appliance, and can realize the differential setting of the data threshold according to the water hardness conditions in different regions.

[0122] In some embodiments, when the historical operation data of the steam generator reaches the second data threshold, if the household appliance with a softened water program can start the softened water program to introduce softened water into the steam generator, but for household appliances without the function of providing softened water, if the steam generator continues to be controlled to operate, an explosion accident may occur. Therefore, when the historical operation data of the steam generator reaches the second data threshold, the user can be prompted to replace the heating tube, which can be achieved through Figure 7 the steps S701 to S702 shown as follows:

[0123] Step S701: Determine that the historical operation data reaches the second data threshold and output a prompt message.

[0124] Here, the prompt message is used to prompt that the historical operation data of the steam generator reaches the second data threshold, so that the user can know the prompt message and replace the heating tube. The prompt message here can be displayed on the display panel of the household appliance, or an alarm sound corresponding to the prompt message can be emitted through the alarm device of the household appliance, or the prompt message can be sent to the user terminal through the sending device of the household appliance for the user to view.

[0125] Step S702: In response to the received operation instruction to replace the heating tube of the steam generator, update the historical operation data to the initial operation data.

[0126] After the user obtains the prompt message, replace the heating tube in the steam generator (including replacing a new heating tube and removing the scale in the original heating tube). Since there is no scale in the replaced heating tube, the historical operation data of the steam generator is restored to the initial value, that is, the historical operation times are cleared and the historical operation duration is cleared.

[0127] In the method provided by the embodiments of the present application, the household appliance prompts the user through the prompt message that the historical operation data of the steam generator reaches the second data threshold, prompts the user to replace the heating tube, and restores the historical operation data to the initial value after replacement to re-detect the operation data of the replaced heating tube. By outputting the prompt message, the user can timely know that the heating tube needs to be replaced, avoiding potential safety accidents caused by continuing to use the steam generator without knowledge.

[0128] The embodiments of the present application further provide a control method, which is applied to a household appliance with a steam generator. Figure 8 This is another schematic flowchart of the implementation process of the control method provided by the embodiments of the present application. As Figure 8 shown, the control method includes the following steps:

[0129] Step S801: Determine to enter the steam generation stage and obtain the historical operation data of the steam generator.

[0130] In one implementation of the embodiment of the present application, the historical operation data may include the historical operation times. The historical operation times are the cumulative number of times entering the steam generation stage, that is, the cumulative number of times of generating steam using the steam generator. Here, the historical operation times are denoted as N, where N is a natural number.

[0131] In another implementation of the embodiment of the present application, the historical operation data may include the historical operation duration. The historical operation duration is the cumulative duration of using the steam function, that is, the cumulative duration of generating steam using the steam generator. Here, the historical operation duration is denoted as T, where T is a natural number.

[0132] In yet another implementation of the embodiment of the present application, the historical operation data may include the historical operation times and the historical operation duration, that is, simultaneously obtaining the number of times and the duration of generating steam using the steam generator cumulatively.

[0133] Step S802, obtain the default operation duration of the steam generator.

[0134] Here, the default operation duration refers to the duration that the steam generator operates by default in the steam generation stage.

[0135] In one implementation, the default operation duration of the steam generator may be the default value set at the factory. In another implementation, according to the water hardness situation in different regions, the default operation duration of the steam generator can be set to a default value matching the region where it is located, which can be achieved by: obtaining the geographical location information of the household appliance; querying the pre-stored relationship table according to the geographical location information to determine the default operation duration of the steam generator.

[0136] Step S803, determine whether the historical operation data reaches the first data threshold.

[0137] When the historical operation data of the steam generator reaches the first data threshold, that is, when the historical operation times N≥N1, or when the historical operation duration T≥T1, it is necessary to further determine whether the historical operation data reaches the first data threshold. At this time, enter step S804; when the historical operation data of the steam generator does not reach the first data threshold, that is, when N<N1, or T<T1, it indicates that there is no need to adjust the operation duration of the steam generator. At this time, enter step S805.

[0138] Step S804, determine whether the historical operation data reaches the second data threshold.

[0139] Here, the second data threshold is greater than the first data threshold.

[0140] When the historical operation data of the steam generator reaches the second data threshold, that is, when the historical operation times N ≥ N2, or when the historical operation duration T ≥ T2, it indicates that the softened water program needs to be started, and at this time, step S807 is entered; when the historical operation data of the steam generator does not reach the second data threshold, that is, when N1 ≤ N < N2, or T1 ≤ T < T2, the default operation duration of the steam generator needs to be adjusted, and at this time, step S806 is entered.

[0141] Step S805, control the steam generator to operate for the default operation duration to determine the end of the steam generation stage.

[0142] When it is determined that the first data threshold is not reached, control the steam generator to operate for the default operation duration to generate steam to ensure the normal use of household appliances. After the steam generation stage ends, step S811 is entered.

[0143] Step S806, adjust the default operation duration according to the historical operation data to obtain the adjusted operation duration.

[0144] In one implementation, the adjustment of the default operation duration can be achieved as follows: obtain the difference between the historical operation data and the first data threshold; determine the adjustment value for adjusting the default operation duration according to the difference and the first data threshold; adjust the default operation duration based on the adjustment value to obtain the adjusted operation duration. After obtaining the adjusted operation duration, step S810 is entered.

[0145] Step S807, determine whether the household appliance can start the softened water delivery program.

[0146] When the household appliance can start the softened water delivery program, step S808 is entered; when the household appliance cannot start the softened water delivery program due to the lack of a softened water program, step S812 is entered.

[0147] Step S808, determine to start the softened water delivery program, and control the delivery device to deliver softened water to the steam generator.

[0148] When the historical operation data reaches the second data threshold, it is considered that the scale amount attached to the heating tube reaches the upper limit value. If the scale amount continues to increase, it will cause a safety accident. At this time, stop continuously supplying hard water containing more soluble calcium and magnesium compounds to the steam generator, start the softened water program, and supply softened water obtained after softening treatment and containing no or less soluble calcium and magnesium compounds to the steam generator. The heating tube heats the softened water, and no more scale will be generated. The steam generator can continue to generate steam while ensuring safety.

[0149] Step S809, adjust the default operation duration according to the second data threshold to obtain the adjusted operation duration.

[0150] In one implementation, adjusting the default operation duration according to the second data threshold can be realized as follows: obtain the difference between the second data threshold and the first data threshold, determine an adjustment value for adjusting the default operation duration according to the difference and the first data threshold, and adjust the default operation duration based on the adjustment value to obtain the adjusted operation duration.

[0151] Step S810, control the steam generator to operate for the adjusted operation duration, and determine the end of the steam generation stage.

[0152] Thus, the steam generator stops generating steam, and the household appliance completes a steam function once.

[0153] Step S811, update the historical operation data based on the operation data in the steam generation stage to obtain the updated historical operation data.

[0154] Here, the operation data in the steam generation stage includes the number of operations and / or the operation duration.

[0155] If the number of operations of the steam generator is accumulated, update the historical number of operations based on the number of operations in the steam generation stage to obtain the updated historical number of operations. That is, after each end of the steam generation stage, add 1 to the number of operations of the steam generator, and the updated historical operation data is the total number of operations of the steam generator.

[0156] If the operation duration of the steam generator is accumulated, update the historical operation duration based on the operation duration in the steam generation stage to obtain the updated historical operation duration. That is, after each end of the steam generation stage, add the operation duration of this entry into the steam generation stage to the operation duration of the steam generator, and the updated historical operation data is the total operation duration of the steam generator.

[0157] After obtaining the updated historical operation data, enter step S814.

[0158] Step S812, output a prompt message.

[0159] Here, the prompt message is used to prompt that the historical operation data of the steam generator reaches the second data threshold, so that the user can obtain the prompt message and replace the heating tube.

[0160] Step S813, in response to the received operation instruction to replace the heating tube of the steam generator, update the historical operation data to the initial operation data.

[0161] After the user obtains the prompt information, replace the heating tube in the steam generator (including replacing the new heating tube and removing the scale in the original heating tube), update the historical operation data of the steam generator to the initial operation data, and obtain the updated historical operation data. At this time, the updated historical operation data is the initial value, that is, the historical operation times are cleared and the historical operation duration is cleared.

[0162] Step S814, save the updated historical operation data.

[0163] Save the updated historical operation data so as to obtain the historical operation data again when entering the steam generation stage next time.

[0164] In the control method provided by the embodiment of the present application, when a household appliance enters the steam generation stage and needs to generate steam, according to the historical operation times of the steam generator or according to the historical operation duration of the steam generator, it is determined whether the historical operation data of the steam generator reaches the first data threshold to determine whether it is necessary to adjust the default operation duration of the steam generator. When it is determined that no adjustment is needed, the steam generator is controlled to generate steam according to the default operation duration; when it is determined that adjustment is needed, it is continued to determine whether the historical operation data of the steam generator reaches the second data threshold. When it is determined that the historical operation data of the steam generator does not reach the second data threshold, the default operation duration is adjusted according to the historical operation data to obtain the adjusted operation duration; when it is determined that the historical operation data of the steam generator reaches the second data threshold, the default operation duration is adjusted according to the second data threshold to obtain the adjusted operation duration. Then, in the current steam generation stage, the steam generator is controlled to operate based on the adjusted operation parameters to generate steam. By adjusting the operation duration of the steam generator through the historical operation data, the operation duration of the steam generator is no longer a fixed value, realizing flexible control of the household appliance to generate steam and meeting the diverse needs of users; in the embodiment of the present application, by adjusting the operation duration of the steam generator, it is ensured that the household appliance achieves treatment effects such as drying, sterilizing, deodorizing, and wrinkle removing.

[0165] The embodiment of the present application further provides a control method, which is applied to a household appliance having a steam generator. The household appliance in the embodiment of the present application is described by taking a dryer as an example.

[0166] With the gradual improvement of people's living standards, the requirements for clothing care are getting higher and higher. There are many washing machines, dryers or washer-dryers with steam generators on the market. Combining steam during the washing process can remove bacteria and odors on clothes, and combining steam ironing during the drying process can remove wrinkles on clothes, providing users with a healthy and comfortable clothing care experience. Currently, the steam generators on the market use heating tubes to heat tap water to generate steam. Since tap water has a certain hardness, frequent use will cause scale to adhere to the heating tubes, (especially in areas like Guangdong where it is hot and humid, the demand for drying clothes is large and the water hardness is high). The scale has poor thermal conductivity and will affect the heat transfer of the heating tubes, affecting the performance of the steam generator. More seriously, it will cause uneven local heating of the heating tubes and lead to an explosion. At the same time, the running time of the steam program carried in the current washing or drying program is factory-set. With the use of the steam function, the fixed time can no longer meet the actual needs of users.

[0167] Figure 9 Another schematic diagram of the implementation process of the control method provided by the embodiment of the present application. This control method is applied to household appliances with a steam function, such as a dryer, as Figure 9 shown, this control method includes the following steps:

[0168] Step S901, start the steam function in the dryer drying program, and obtain the cumulative number of times N that this function has been used.

[0169] Step S902, judge the size relationship between the cumulative number of times N and N1, N2, where N1 < N2.

[0170] Step S903, if N < N1, then count N = N + 1, and run the steam generator for a preset duration according to the preset duration of the steam function.

[0171] After starting the steam function in the dryer drying program next time, the obtained N is the updated count N.

[0172] Step S904, if N1 ≤ N ≤ N2, then count N = N + 1, and adjust the preset duration of running the steam generator, and run the steam generator according to the adjusted running duration.

[0173] After starting the steam function in the dryer drying program next time, the obtained N is the updated count N.

[0174] Step S905, if N ≥ N2, then give an alarm to prompt the user to remove the scale in time.

[0175] Here, the user can be prompted through the display panel of the dryer, or the dryer can be interconnected with a server or a mobile terminal, etc., and the prompt message can be sent to the user terminal.

[0176] Step S906: When the user removes the scale, set N to zero.

[0177] After setting to zero, when the steam function in the dryer drying program is started again, the counting restarts.

[0178] The control method provided by the embodiments of the present application can be applied to household appliances with a steam function, such as dryers, dishwashers, and steam irons. It can determine whether to adjust the operation time (steam volume) or whether to replace and clean the heating tube according to the number of program uses, so as to achieve flexible control of the steam function duration; during the startup process, the softened water program can be started to reduce the adverse impact of hard water on the heating tube; it can differentially adjust the preset duration of the steam function according to the water hardness conditions in different regions (such as the household appliance is interconnected with the server to obtain the water quality data of the geographical location to determine the water hardness conditions), so as to achieve differential setting of the preset duration; by alarming to remind the user, the user can remove the scale in time, reducing the potential safety hazards in the use of household appliances.
