Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smart home appliances, and particularly provides a control method for a washing device and the 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. In order to better save energy, many washing machines are provided with a water retention function. When the last rinsing is finished, the water is temporarily stored in the washing tub for a period of time, and the user is prompted. The user can connect the water stored in the washing tub to a storage container for other purposes such as washing a mop, flushing a toilet, etc.

[0003] However, the water retention function is an independent auxiliary function, which is only executed when the user selects the water retention function. However, in actual application, the user may forget to select the water retention function, or the elderly may not select the water retention function, resulting in that the water retention function cannot be executed, cannot play its role, causes waste of water resources, and further affects the user's use experience.

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

[0005] The present application aims to solve the above technical problems, i.e., to solve the problem that the water retention function of the existing washing device cannot be automatically executed.

[0006] In a first aspect, the present application provides a control method for a washing device, the control method comprising the following steps: obtaining a function to be executed of the washing device; determining whether a water retention function of the washing device is activated based on the function to be executed; obtaining a historical number of times that the water retention function is executed in a case where it is determined that the water retention function is not activated; determining whether the historical number of times is greater than a preset number of times; and selectively causing the washing device to activate the water retention function according to the determination result.

[0007] In a preferred technical solution of the above control method, the step of "selectively causing the washing device to activate the water retention function according to the determination result" specifically comprises: if the historical number of times is greater than or equal to the preset number of times, causing the washing device to activate the water retention function.

[0008] In a preferred technical solution of the above control method, after the washing device activates the water retention function, the control method further comprises: causing the washing device to execute the water retention function at a preset time node, wherein the preset time node is a historical time node at which the water retention function is executed; and / or sending a prompt information to prompt the user that the washing device automatically sets the water retention function.

[0009] In the preferred technical solution of the control method, the step of selectively causing the washing device to activate the water retaining function according to the judgment result further comprises: if the historical number of times is less than the preset number of times, causing the washing device not to activate the water retaining function.

[0010] In the preferred technical solution of the control method, the step of obtaining the historical number of times that the water retaining function is executed specifically comprises: obtaining the identity of the user; judging the category to which the user belongs based on the identity; and selectively directly obtaining the historical number of times according to the judgment result.

[0011] In the preferred technical solution of the control method, the step of selectively directly obtaining the historical number of times according to the judgment result specifically comprises: if the user belongs to a first category of users, directly obtaining the historical number of times that the water retaining function is executed within a preset time period; and wherein the preset time period is any time period before the washing device performs the current washing and protecting operation.

[0012] In the preferred technical solution of the control method, the step of selectively directly obtaining the historical number of times according to the judgment result further comprises: if the user belongs to a second category of users, obtaining a historical number of times that the drain time difference of the washing device is greater than a preset time, and taking the historical number of times as the historical number of times; or if the user belongs to the second category of users, obtaining a historical number of times that the pause key of the washing device is operated during the drain operation, and taking the historical number of times as the historical number of times.

[0013] In the preferred technical solution of the control method, the step of obtaining the identity of the user specifically comprises: obtaining the age of the user; and determining the identity according to the age.

[0014] In the preferred technical solution of the control method, the control method further comprises: in the case where it is determined that the water retaining function is activated, causing the washing device to directly perform the to-be-executed function.

[0015] In a second aspect, the present application provides a washing device, comprising: a processor; a memory for storing a plurality of program codes; the program codes are adapted to be loaded and executed by the processor to perform the control method of any one of the above preferred technical solutions.

[0016] In the preferred technical solution of the control method of the present application, the to-be-executed function of the washing machine is obtained; it is judged whether the water retaining function of the washing machine is activated based on the to-be-executed function; in the case where the water retaining function is not activated, the historical number of times that the water retaining function is executed is obtained; it is judged whether the historical number of times is greater than a preset number of times; and the washing machine is selectively caused to activate the water retaining function according to the judgment result.

[0017] Compared with the prior art, the present application can accurately determine whether the user often uses or is used to using the water retention function, whether the user needs to use the water retention function, and whether the water retention function needs to be activated according to the determination result of whether the historical number of times that the water retention function is executed is greater than a preset number of times when it is determined that the water retention function is not activated, and based on this, the washing machine is selectively activated to execute the water retention function, so that even when the user forgets to select the water retention function, the washing machine can automatically execute the water retention function, ensures that the water retention function can be automatically activated when the user needs to execute the water retention function, fully plays the role of the water retention function, avoids waste of water resources, and further improves the user experience.

[0018] Further, after the washing machine activates the water retention function, the washing machine executes the water retention function according to a preset time node, wherein the preset time node is a historical time node at which the water retention function is executed, so that the user can use the water retention function according to the user's usage habits, and the washing water in the same time range is temporarily stored, which better meets the user's usage requirements.

[0019] Further, after the washing machine activates the water retention function, a prompt information is sent, which can timely prompt the user that the washing machine automatically sets the water retention function, and remind the user to timely take the water stored in the washing tub to a storage container for washing a mop, flushing a toilet, etc., so as to avoid that the washing water is stored in the washing tub for a long time, to avoid breeding of bacteria, generation of odor, etc., and to improve the hygiene and safety of the washing machine.

[0020] Further, the identity of the user is obtained, and based on the identity, the category to which the user belongs is determined, different categories of users have different usage habits and different usage methods, and some users may directly use the water retention function, while some users do not use the water retention function but retain water through other ways, therefore, based on the category of the user, it can be accurately determined whether the historical number of times that the water retention function is executed can be directly obtained, and thus it can be accurately determined whether the water retention function needs to be activated, to avoid misjudgment, and further improve the user experience.

[0021] Further, if the user belongs to the first category of users, it means that the user is middle-aged, young or a teenager, who can well operate the washing machine and can autonomously select the water retention function, and the washing machine has recorded the historical number of times that the water retention function has been used, in this case, the historical number of times that the water retention function is executed within a preset time period can be directly obtained.

[0022] Further, if the user belongs to the second type of user, it is indicated that the user is middle-aged or old and cannot operate the washing machine well, and in most cases cannot independently select the water retention function. The user can store the washing water in a container such as a washing basin by a manual method, so that the draining time of the washing machine is prolonged, or the draining of the washing machine is paused, and the like. Therefore, the historical number of times that the water retention function is executed cannot be obtained. In this case, the historical statistical number of times that the draining time difference of the washing machine is greater than the preset time can be obtained, and the historical statistical number of times is used as the historical number of times. Alternatively, the historical operation number of times that the pause key of the washing machine is operated during the draining operation can be obtained, and the historical operation number of times is used as the historical number of times.

[0031] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand 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 solutions of the present application are not limited thereto. In actual applications, the washing device can also be any one of a washer-dryer, a steam washing device, a shoe washing machine, and the like. The washing machine can be a pulsator washing machine or a drum washing machine.

[0032] It should be noted that in the description of the present application, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0033] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the term "set" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0034] Based on the technical problems proposed in the background art, the present application provides a control method for a washing machine, which aims to accurately determine whether the user often uses or is used to using the water retention function, whether the user needs to use the water retention function, and whether the water retention function needs to be activated according to the determination result of whether the historical number of times that the water retention function is executed is greater than a preset number of times in the case that the water retention function is not activated, and based on this, selectively makes the washing machine activate the water retention function, so that even in the case that the user forgets to select the water retention function, the washing machine can automatically execute the water retention function, ensures that the water retention function can be automatically activated in the case that the user needs to execute the water retention function, fully plays the role of the water retention function, avoids the waste of water resources, and further improves the user experience.

[0035] Firstly, refer to Figure 1 The control method of the present application is described. Among them, Figure 1 is the main flow chart of the control method of the present application.

[0036] As Figure 1 shown, the control method of the present application includes the following steps:

[0037] S100, acquiring a function to be executed of the washing machine;

[0038] S200, judging whether the water retention function of the washing machine is activated based on the function to be executed;

[0039] S300, acquiring the historical number of times that the water retention function is executed in the case that it is determined that the water retention function is not activated;

[0040] S400, judging whether the historical number of times is greater than a preset number of times;

[0041] S500, selectively making the washing machine activate the water retention function according to the determination result.

[0042] In step S100, after the washing machine is started, the user sets a washing and protecting program or the washing machine recommends a washing and protecting program, and a function to be executed corresponding to the washing and protecting program is acquired. The function to be executed includes, but is not limited to, a washing function, a rinsing function, a water injection function, a water draining function, a spin-drying function, a water retention function, and other functions. The washing machine with a drying function can further include a drying function.

[0043] In step S200, if the function to be executed includes the water retention function, it is indicated that the user has set the water retention function or the washing and protecting program recommended by the washing machine has the water retention function, and thus it is determined that the water retention function has been activated. If the function to be executed does not include the water retention function, it is indicated that the user has not set the water retention function or the washing and protecting program recommended by the washing machine does not have the water retention function, and thus it is determined that the water retention function has not been activated.

[0044] Reference will be made below Figures 2 to 4 to the control method for acquiring the historical number of times according to the present application. In this regard, Figure 2 the control method for acquiring the historical number of times according to the present application is described. Figure 1 Figure 3 The control method for acquiring the user identity according to the present application is described. Figure 4 The control method for acquiring the historical number of times according to the present application is described. Figure 2

[0045] As shown in Figure 2 , in step S300, the step of "acquiring the historical number of times that the water retention function is executed" specifically includes:

[0046] S311, acquiring the identity of the user;

[0047] S312, judging the category to which the user belongs based on the identity;

[0048] S313, selectively directly acquiring the historical number of times according to the judgment result.

[0049] The category to which the user belongs includes a first category of users and a second category of users. The first category of users includes teenagers, young people, and middle-aged people. The second category of users includes middle-aged and old people. Of course, the division of the category to which the user belongs is not limited to the above-mentioned manner, but can also be divided into three categories of users. The first category of users includes teenagers, young people, and middle-aged people. The second category of users includes middle-aged and old people. The third category of users includes infants, young children, and children. Those skilled in the art can flexibly adjust and set the division of the category of users according to actual use requirements. The control method according to the present application is further described below by taking the first category of users and the second category of users as examples.

[0050] As shown in Figure 3 , in step S311, the step of "acquiring the identity of the user" specifically includes:​​

[0051] S321. Obtain the user's age;

[0052] S322. Identify based on age.

[0053] In step S321, the basic information of the user is obtained. The user's basic information includes gender, age, contact information, etc. The user's age can be determined through the basic information.

[0054] Alternatively, the washing machine may be equipped with an image acquisition mechanism, such as a camera or webcam, to capture the user's facial image and determine the user's age based on the facial image.

[0055] In step S322, the detected age is compared with the age lookup table pre-stored on the washing machine, and the user's identity is determined based on the comparison result. For example, if the detected age is 16, the user is definitely a teenager and belongs to the first type of user; or, if the detected age is 28, the user is definitely a young adult and belongs to the first type of user; if the detected age is 46, the user is definitely middle-aged and belongs to the first type of user; if the detected age is 66, the user is definitely middle-aged or elderly and belongs to the second type of user; if the detected age is 78, the user is definitely elderly and belongs to the second type of user.

[0056] In an alternative implementation, the washing machine is equipped with a height detection mechanism, such as an infrared sensor or a radar sensor, to detect the user's height. The detected height is then compared with a height comparison chart pre-stored on the washing machine to determine the user's identity.

[0057] It should be noted that the methods for determining user identity are not limited to those listed above. The user's identity can also be determined by obtaining the user's voice. Regardless of the method used, as long as the user's identity can be determined, it is acceptable.

[0058] like Figure 4 As shown, step S313, "selectively and directly obtaining historical counts based on the judgment result," specifically includes:

[0059] S331. If the user belongs to the first type of user, directly obtain the historical number of times the water retention function has been executed within the preset time period;

[0060] S332. If the user belongs to the second type of user, obtain the historical statistics of the number of times the washing machine's drainage time difference is greater than the preset time, and use the historical statistics as the historical count.

[0061] The historical number of times is the number of times the water retention function has been used within 10 days before the current execution of the washing and protecting operation of the washing machine. Of course, the preset time period is not limited to the above-mentioned time period, and can be 5 days, 15 days, or other time periods before the current execution of the washing and protecting operation of the washing machine. Those skilled in the art can flexibly adjust and set the preset time period according to the use of the washing machine by the user.

[0062] In step S331, if the user belongs to the first type of user, it means that the user is middle-aged, young, or a teenager, and can operate the washing machine well and can independently select the water retention function. In addition, the washing machine records the use of the water retention function by the user during the use of the washing machine and stores and counts the number of times the water retention function is used. In this case, the historical number of times the water retention function is executed within 20 days before the current execution of the washing and protecting operation of the washing machine can be directly obtained, for example, 1 time or 5 times or other number of times.

[0063] In step S332, if the user belongs to the second type of user, it means that the user is middle-aged or old and cannot operate the washing machine well and cannot independently select the water retention function in most cases. The user may store the washing water in a container such as a washing basin by a manual method, so that the draining time of the washing machine is prolonged, and therefore the historical number of times the water retention function is executed cannot be obtained. In this case, the historical counting number of times the draining time difference is greater than the preset time can be obtained, and the historical counting number of times also reflects the habit of the user to retain the washing water. Therefore, the historical counting number of times can be used as the historical number of times.

[0064] The washing water can be water for washing clothes or water for rinsing clothes.

[0065] Further, the draining time difference is the difference between the draining times of any two times of the draining operation in the process of the washing machine executing the washing and protecting program. For example, the washing machine executes three times of the draining operation in the process of the last time of executing the washing and protecting program, and the draining times of the three times of the draining operation are 30 s, 32 s, and 50 s, respectively. The historical draining time differences are 5 s, 20 s, and 18 s, respectively.

[0066] Further, for example, the preset time is 15 s, and 5 s, 20 s, and 18 s are compared with 15 s, respectively. Among them, 20 s and 18 s are greater than 15 s, which means that the draining time of one time is longer, and it is possible that the user stores the washing water in a container such as a washing basin by a manual method, so that the draining time is prolonged. Therefore, the number of times the draining time difference is greater than the preset time is counted, that is, the historical counting number of times, and the draining stage in which the draining time is prolonged, for example, the third draining process, is counted.

[0067] It can be seen that although the user does not set the water retention function, the user still manually retains the washing water, that is, the user has the habit of retaining the washing water, and the historical statistical number of times that the drain time difference is greater than the preset time can also reflect whether the user is used to retaining the washing water, so the historical statistical number of times can be used as the historical number of times.

[0068] It should be noted that the above-mentioned preset time, drain time and drain time difference are only exemplary and are not limited, and those skilled in the art can flexibly adjust and set the preset time according to the use requirements in actual application, and determine the drain time and the drain time difference according to the actual detection result.

[0069] It should be noted that in the above process, steps S331 and S332 have no sequence and are parallel, and are only related to the judgment result of the category to which the user belongs, and the corresponding steps can be executed according to different judgment results.

[0070] Alternatively, in an alternative embodiment, if the user belongs to the second type of user, it means that the user is middle-aged or old and cannot operate the washing machine well, and cannot independently select the water retention function in most cases, and may store the washing water in a container such as a washing basin by a manual method. In the process of storing the washing water, in order to avoid the washing water from being left on the ground, the user will operate the pause key to pause the washing machine, and when the drain pipe is placed in an external container such as a washing basin, the washing machine will be restarted, so the historical number of times that the water retention function is executed cannot be obtained. In this case, the historical operation number of times that the pause key of the washing machine is operated in the process of the drain operation can be obtained, and the historical operation number of times also reflects that the user has the habit of retaining the washing water, so the historical operation number of times can be used as the historical number of times.

[0071] Further, the washing machine not only counts the historical operation number of times that the pause key of the washing machine is operated in the process of the drain operation, but also counts the time node at which the pause key is operated in the process of the drain operation, for example, the pause key is operated in the process of the last execution of the drain operation, or the pause key is operated in the process of the second execution of the drain operation.

[0072] The following refers to Figure 5 The control method for selectively activating the water retention function of the present application is described. Among them, Figure 5 is a flow chart of the control method for selectively activating the water retention function of the present application.

[0073] As Figure 5 shown, the step of "selectively activating the water retention function of the washing machine according to the judgment result" in step S500 specifically includes:

[0074] S511, if the historical number of times is less than the preset number of times, the washing machine is caused not to activate the water retention function;

[0075] S512, if the historical number of times is greater than or equal to the preset number of times, the washing machine is caused to activate the water retention function.

[0076] In step S511, if the historical number of times is less than the preset number of times, for example, the preset number of times is 3 times, and the obtained historical number of times is 1 time, which is less than the preset number of times, it indicates that the user only occasionally uses the water retention function, or only tries to use the water retention function, and the user does not regard the water retention function as a use habit, and it can be considered that the user does not need to retain the washing water, so the washing machine is caused not to activate the water retention function, and the washing machine directly runs according to the function to be executed.

[0077] In step S512, if the historical number of times is greater than or equal to the preset number of times, for example, the preset number of times is 3 times, and the obtained historical number of times is 5 times, which is greater than the preset number of times, it indicates that the user often uses the water retention function, and the user has regarded the water retention function as a use habit, and it can be considered that the user needs to retain the washing water, and the user may have forgotten to set the water retention function in the process of setting the washing and protection program this time, or the user may have forgotten to set the water retention function after the washing machine recommends the washing and protection program, so the washing machine is caused to activate the water retention function, and the washing water can also be retained during the running of the washing machine this time, and the user experience is further improved.

[0078] It should be noted that in the above process, step S511 and step S51332 have no sequence and are parallel, and are only related to the judgment result of whether the historical number of times is greater than the preset number of times, and the corresponding steps are executed according to different judgment results.

[0079] The control method of the present application will be further described below with reference to Figure 6 The control method of the present application will be further described below with reference to Figure 6 is the complete flowchart of the control method of the present application.

[0080] As shown in Figure 6 After the washing machine activates the water retention function, the control method further comprises:

[0081] S600, the washing machine is caused to execute the water retention function according to a preset time node;

[0082] The preset time node is a historical time node when the water retention function is executed, for example, the water retention function is executed during the last execution of the draining operation, or the draining time is extended, or the pause key is operated, or the water retention function is executed during the second execution of the draining operation, or the draining time is extended, or the pause key is operated.

[0083] In step S600, the washing machine is caused to perform the water retention function in the process of performing the last drainage operation in the current operation, which is more in line with the user's habit of retaining washing water and better meets the user's use demand. Of course, the washing machine can also be caused to perform the water retention function in the process of performing the second drainage operation in the current operation, or the water retention function can be performed at other time nodes at which the user has ever retained washing water.

[0084] Further, after the washing machine activates the water retention function, a prompt information can be sent to timely prompt the user that the washing machine has automatically set the water retention function, and remind the user to timely pour the water stored in the washing tub into a storage container for washing a mop, flushing a toilet, etc., so as to avoid that the washing water is stored in the washing tub for a long time, to avoid breeding of bacteria and generation of odor, and to improve the hygiene and safety of the washing machine.

[0085] Preferably, the washing machine can send the prompt information in the form of voice or ring tone. The washing machine can also send the prompt information to a terminal device such as a mobile phone, a tablet computer, a smart bracelet, etc. of the user.

[0086] Again referring to Figure 6 , in the case where it is determined that the water retention function is activated, the control method further comprises:

[0087] S700, causing the washing machine to directly perform the to-be-performed function.

[0088] In the case where it is determined that the water retention function is activated, it indicates that the user has set the water retention function, or the washing machine-recommended washing and protection program has the water retention function by itself, and at this time, the washing machine can directly perform the to-be-performed function, so as to store the washing water in the washing tub.

[0089] It should be noted that in the above process, step S300 and step S700 have no sequence and are parallel, and are only related to the determination result of whether the water retention function is activated, and the corresponding step can be performed according to different determination results.

[0090] Hereinafter, with reference to Figure 7 , a possible control flow of the present application is introduced. Among them, Figure 7 is a logic diagram of the control method of the present application.

[0091] As shown in Figure 7 , a possible complete flow of the control method of the present application is:

[0092] S801, after the washing machine starts to operate, acquiring a to-be-performed function of the washing machine;

[0093] S802, judging whether a water retention function of the washing machine is activated based on the to-be-performed function; if not, step S803 is performed; if yes, step S811 is performed.

[0095] S804, judging the category to which the user belongs based on the identity;

[0096] If the user belongs to the first category of users, step S805 is executed;

[0097] If the user belongs to the second category of users, step S806 is executed;

[0098] S805, directly obtaining the historical number N of times that the water retention function is executed within a preset time period;

[0099] S806, obtaining the historical statistical number of times that the draining time difference of the washing machine is greater than a preset time, and taking the historical statistical number of times as the historical number N;

[0100] After step S805 or step S806, step S807 is executed;

[0101] S807, judging whether N>3 is true? If yes, step S808 is executed; if no, step S810 is executed;

[0102] S808, causing the washing machine to activate the water retention function;

[0103] After step S808, step S809 is executed;

[0104] S809, causing the washing machine to execute the water retention function according to a preset time node and sending a prompt message;

[0105] S810, causing the washing machine not to activate the water retention function;

[0106] After step S810, step S811 is executed;

[0107] S811, causing the washing machine to execute a to-be-executed function.

[0108] It should be noted that the above embodiment is only one preferred embodiment of the present application, and is used to illustrate the principle of the method of the present application, and is not intended to limit the protection scope of the present application. In actual application, a person skilled in the art can distribute the above functions by different steps according to needs, that is, the steps in the embodiment of the present application are further decomposed or combined. For example, the steps of the above embodiment can be combined into one step, or can be further split into multiple sub-steps to complete all or part of the functions described above. The names of the steps involved in the embodiment of the present application are only used to distinguish the steps, and are not considered as a limitation of the present application.
