Description

Technical Field

[0001] This invention relates to the field of washing machine technology, and in particular to a filter cleaning reminder method, device, washing machine, and storage medium. Background Technology

[0002] With the continuous improvement of manufacturing technology and the increasing demands of daily life, washing machines have entered thousands of households and become one of the most commonly used home appliances. Generally speaking, the water inlet valve of a current washing machine is connected to a faucet via a water inlet pipe on one end, and to the washing machine itself on the other end. In most areas, tap water contains impurities such as sediment and heavy metals. These impurities entering the washing machine not only cause the water tank and other components to turn yellow and discolored, affecting its appearance and usability, but also impact washing performance. For washing machines with heating functions, scale and other impurities adhering to the heating element over time will affect heating efficiency, increase power consumption, and shorten the lifespan of the heating element.

[0003] To prevent impurities from entering the washing machine, existing technology adds a filter device inside the water inlet valve to filter impurities in tap water. However, if the filter screen is not cleaned after long-term use, it is prone to clogging. Clogging will cause the water inlet time to be longer, which will make the washing machine unable to be used normally. Summary of the Invention

[0004] This invention provides a filter cleaning reminder method, device, washing machine, and storage medium, aiming to solve the problems of filter blockage and washing machine malfunction caused by untimely filter cleaning.

[0005] In a first aspect, embodiments of the present invention provide a filter cleaning reminder method, comprising:

[0006] If this is the first time the washing machine is communicating with the application, the user address and water quality map information are obtained from the application.

[0007] The water quality area is determined based on the user address and the water quality map information;

[0008] If the water quality area is a preset water quality area, the number of filter items is obtained from the preset storage area, and the usage threshold is determined based on the number of items and the water quality area.

[0009] If the washing machine and the application are not communicating for the first time, the number of uses is obtained from the preset storage area, and it is determined whether the number of uses is greater than the number of uses threshold.

[0010] If the number of uses exceeds the usage threshold, a prompt code for cleaning the filter is displayed based on the response information sent by the application, and the prompt code is sent to the application, or a push command is sent to the application so that the application pushes the prompt information for cleaning the filter to the user according to the push command.

[0011] Secondly, embodiments of the present invention also provide a filter cleaning reminder device, which includes:

[0012] The first acquisition unit is used to acquire user address and water quality map information from the application if the washing machine and the application are communicating for the first time.

[0014] The second determining unit is used to obtain the number of filter items from the preset storage area if the water quality area is a preset water quality area, and determine the usage threshold based on the number of items and the water quality area.

[0015] The judgment unit is used to obtain the number of uses from the preset storage area and determine whether the number of uses is greater than the number of uses threshold if the washing machine and the application are not communicating for the first time.

[0016] The prompting unit is configured to, if the number of uses exceeds the usage threshold, display a prompt code for cleaning the filter based on the response information sent by the application, and send the prompt code to the application, or send a push instruction to the application so that the application pushes the prompt information for cleaning the filter to the user according to the push instruction.

[0017] Thirdly, embodiments of the present invention also provide a washing machine, which includes a water inlet valve, a memory, and a processor. The water inlet valve includes a filter screen, the memory stores a computer program, and the processor executes the computer program to implement the above-described method.

[0018] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program that, when executed by a processor, can implement the above-described method.

[0019] This invention provides a filter cleaning reminder method, device, washing machine, and storage medium. The method includes: if the washing machine and the application are communicating for the first time, obtaining the user's address and water quality map information from the application; determining a water quality area based on the user's address and the water quality map information; if the water quality area is a preset water quality area, obtaining the number of filter entries from a preset storage area, and determining a usage frequency threshold based on the number of entries and the water quality area; if the washing machine and the application are not communicating for the first time, obtaining the usage frequency from the preset storage area and determining whether the usage frequency is greater than the usage frequency threshold; if the usage frequency is greater than the usage frequency threshold, displaying a filter cleaning reminder code based on the response information sent by the application, and sending the reminder code to the application, or sending a push command to the application so that the application pushes the filter cleaning reminder information to the user according to the push command. The technical solution of this invention determines the water quality area based on the user's address and water quality map information, and determines the usage threshold based on the water quality area and the number of items on the filter screen. When the usage count exceeds the usage threshold, the user is reminded to clean the filter screen in time, ensuring the cleanliness of the filter screen and avoiding long water intake time due to filter screen clogging, thus ensuring the normal use of the washing machine.

[0033] Please see Figure 1 , Figure 1 This is a flowchart illustrating the filter cleaning reminder method provided in an embodiment of the present invention. The filter cleaning reminder method will be described in detail below. Figure 1 As shown, the method includes the following steps S100-S140.

[0034] S100. If this is the first time the washing machine is communicating with the application, then obtain the user address and water quality map information from the application.

[0035] In this embodiment of the invention, when a user completes registration in the application and logs in for the first time using their registered account and password, the application obtains the user's address via GPS technology based on the address information entered during registration. This user address is then associated with water quality map information pre-stored within the application, and the association is saved. Understandably, the application also binds the washing machine's corresponding ID number to the application to enable communication between the application and the washing machine. In practical applications, if the user clicks the connection button in the application interface for the first time, the application initiates its first communication with the washing machine. When the control center in the washing machine recognizes this as the first communication, it updates the communication count. The initial value of the communication count is 0, and after the update, it becomes 1. The control center then retrieves the user's address and the water quality map information from the application. It should be noted that in this embodiment, the application is an APP application. The washing machine also includes a water inlet valve, which comprises components such as a filter screen, a coil frame, and a coil guide rail.

[0036] It should also be noted that the water quality map information is needed in this embodiment because the water quality of tap water tends to decline from the treatment plant to the user's tap, even exceeding national standards. This is because the water flows through the water pipe network for a long time, undergoing a series of physical, chemical, electrochemical, and microbiological processes, resulting in secondary pollution. Studies on various impurities in water show that tap water entering users' homes contains impurities during its transportation through various levels of pipes. Foreign objects, mainly rust or fine sand particles, are frequently seen in water. Microorganisms or other debris may also enter the secondary water supply storage tank due to inadequate protection. Leakage of activated carbon used in emergency treatment of raw water pollution can also result in black suspended solids.

[0037] Studies on water hardness have revealed differences in water hardness across various regions of the country, and the amount of calcium in tap water varies with hardness. 2+ Mg 2+ The varying ion content leads to the formation of carbonate deposits at the inlet valve filter of a washing machine. In other words, the higher the water hardness, the more deposits form, and the shorter the clogging time. Furthermore, after tap water passes through pipes and is treated in water towers, its temperature rises after exposure to sunlight, further accelerating the formation of deposits in hard water.

[0038] (1)Ca 2+ Mg 2+ Reactions that form precipitates from ions:

[0039] Ca(HCO3)2=CaCO3↓+H2O+CO2↑

[0040] Mg(HCO3)2=MgCO3↓+H2O+CO2↑

[0041] Since CaCO3 is insoluble and MgCO3 is slightly soluble, magnesium carbonate can react with water to form magnesium carbonate under further temperature increases.

[0042] (2) Magnesium hydroxide, which is even less soluble:

[0043] MgCO3 + H2O = Mg(OH)2↓ + CO2↑

[0044] Therefore, it can be seen that the main components of the precipitate formed by high-hardness tap water are CaCO3 and Mg(OH)2. Comprehensive analysis shows that impurities in the water, such as silt and rust particles, are generally larger than 5 μm, while the diameter of CaCO3 and Mg(OH)2 precipitate particles is generally larger than 0.02 μm. This means that silt and rust particles are more likely to clog the filter screen. Furthermore, as the pore size of the filter screen decreases, CaCO3 and Mg(OH)2 precipitate particles will also clog the filter screen.

[0045] S110. Determine the water quality area based on the user address and the water quality map information.

[0046] In this embodiment of the invention, after the control center obtains the user address and the water quality map information, it determines the water quality region based on the user address and the water quality map information. Specifically, it first traverses the water quality map information based on the user address to obtain the location region; then, it obtains the water quality region from the location water quality mapping table based on the location region. It should be noted that in this embodiment, the water hardness and impurity content vary in different water quality regions.

[0047] S120. If the water quality area is a preset water quality area, the number of filter items is obtained from the preset storage area, and the usage threshold is determined based on the number of items and the water quality area.

[0048] In this embodiment of the invention, after determining the water quality region, it is determined whether the water quality region is a preset water quality region. If the water quality region is the preset water quality region, the number of filter entries is obtained from a preset storage area, wherein the preset storage area is memory or a storage device, and the storage device is LocalStorage, which is a persistent storage method. The preset water quality regions include a first preset water quality region, a second preset water quality region, a third preset water quality region, a fourth preset water quality region, a fifth preset water quality region, and a sixth preset water quality region. It should be noted that, in this embodiment, the water quality in the first preset water quality region is the worst, and the water quality in the sixth preset water quality region is the best. Understandably, the water quality in the second, third, fourth, and fifth preset water quality regions gradually improves. The entry region is obtained by traversing the entry frequency table according to the number of entries. The usage frequency threshold is then found from the entry region according to the water quality region. For example, assuming the number of entries is 140, and the water quality area is the third preset water quality area, the usage thresholds for the first, second, third, fourth, fifth, and sixth preset water quality areas corresponding to the 140 entries are 120, 180, 240, 300, 360, and 720 respectively. Therefore, the usage threshold for the water quality area is 240. It should also be noted that in this embodiment, the number of entries in the filter screen is generally selected to be 100 mesh or more. The larger the number of entries, the smaller the pore size in the filter screen, i.e., the pore size is less than 0.15 μm, in order to effectively block impurities such as silt and rust. Understandably, the usage thresholds for the preset water quality areas correspond to different numbers of entries. For example, if the number of entries is 160, the usage thresholds for the first preset water quality area, the second preset water quality area, the third preset water quality area, the fourth preset water quality area, the fifth preset water quality area, and the sixth preset water quality area are 180, 240, 300, 360, 720, and 900, respectively.

[0049] Furthermore, if the water quality area is a preset water quality area, the specific process is as follows: Figure 2As shown, the process includes the following steps: S121, setting a first preset water quality area as the target water quality area; S122, determining whether the water quality area is the target water quality area. If the water quality area is the target water quality area, then proceed to step S123; otherwise, proceed to step S124; S123, determining that the water quality area is a preset water quality area; S124, setting the next preset water quality area as the target water quality area, and returning to proceed to step S122. It should be noted that, in this embodiment, the water quality region can be determined as a preset water quality region by using the water quality identifier corresponding to the water quality region. For example, if the water quality identifier of the water quality region is WQ3, and the water quality identifiers of the first preset water quality region, the second preset water quality region, the third preset water quality region, the fourth preset water quality region, the fifth preset water quality region, and the sixth preset water quality region are WQ1, WQ2, WQ3, WQ4, WQ5, and WQ6 respectively, and WQ3 matches WQ3, then the water quality region is determined to be the preset water quality region.

[0050] Furthermore, in the initial stage of use, the filter screen is generally clogged due to the accumulation of impurities such as silt and rust. Some filter screen pores become blocked or smaller. Depending on the water hardness, precipitates such as CaCO3 and Mg(OH)2 in the water also have difficulty passing through the filter screen and become clogged at the front end of the filter screen along with silt, rust and other impurities. The greater the water hardness, the more serious this effect is, and understandably, the lower the threshold for the number of uses.

[0051] S130. If the washing machine and the application are not communicating for the first time, the number of uses is obtained from the preset storage area, and it is determined whether the number of uses is greater than the number of uses threshold.

[0052] In this embodiment of the invention, if the washing machine and the application are not communicating for the first time, it indicates that the communication count is not 1. At this time, the control center has determined the water quality area of ​​the working environment where the washing machine is located. During subsequent use of the washing machine, the washing machine may or may not communicate with the application. For example, if the user exits the application, the control center obtains the number of uses from the preset storage area, wherein the number of uses is the number of times the washing machine has been used. It determines whether the number of uses is greater than the number of uses threshold, and determines whether it is necessary to send a prompt code or prompt message indicating that the filter needs to be cleaned based on the judgment result.

[0053] S140. If the number of uses exceeds the usage threshold, then according to the response information sent by the application, a prompt code for cleaning the filter is displayed, and the prompt code is sent to the application, or a push instruction is sent to the application so that the application pushes the prompt information for cleaning the filter to the user according to the push instruction.

[0054] In this embodiment of the invention, if the number of uses exceeds the usage threshold, a detection command is sent to the application. The application receives the detection command and checks whether the user is online to obtain a detection result. The detection result is encapsulated into a sendable response message. The application displays a filter cleaning prompt code based on the response message and sends the prompt code to the application or sends a push command to the application so that the application pushes a filter cleaning prompt message to the user based on the push command. It should be noted that displaying the filter cleaning prompt code and sending the prompt code to the application includes displaying the filter cleaning prompt code on the washing machine's human-machine interface, sending the prompt code to the application, and displaying the prompt code on the application's interface. The user can find out from the instruction manual that the prompt code represents the meaning of cleaning the filter.

[0055] In some embodiments, such as this embodiment, as Figure 3 As shown, step S140 may include steps S141-S143.

[0056] S141. Receive the response information sent by the application and parse the response information to obtain the detection result;

[0057] S142. If the detection result indicates that the user is online, a prompt code for cleaning the filter is displayed, and the prompt code is sent to the application.

[0058] S143. If the detection result indicates that the user is not online, a push notification is sent to the application so that the application can push a prompt message to the user to clean the filter screen according to the push notification.

[0059] In this embodiment of the invention, a response message sent by the application is received and parsed to obtain a detection result. If the detection result indicates that the user is online, meaning the user has not exited the application, a prompt code for cleaning the filter is displayed and sent to the application. If the detection result indicates that the user is offline, meaning the user has exited the application, a push notification is sent to the application, causing the application to push a prompt message for cleaning the filter to the user according to the push notification. Understandably, the application can send the prompt message via WeChat, SMS, or other means to ensure the user cleans the filter promptly and maintains its cleanliness. It should be noted that in this embodiment, timely reminders for filter cleaning prevent prolonged water intake due to filter clogging, ensuring the normal operation of the washing machine.

[0060] Furthermore, after receiving the prompt code or message, the user will choose whether to perform a wash. If the control center of the washing machine receives a preset wash start command within a preset time, it will control the washing machine to enter the filter cleaning mode. After the wash is completed, a preset wash completion command will be sent. If the control center receives the preset wash completion command, it will reset the usage count to zero to start counting for the next usage cycle. It should be noted that, in this embodiment, if the control center does not clean the filter after sending the preset number of prompt codes or push commands, the control center will control the washing machine to automatically enter the filter cleaning mode.

[0061] Figure 4 This is a flowchart illustrating a filter cleaning reminder method according to another embodiment of the present invention, as shown below. Figure 4 As shown, the method includes steps S200-S270, and steps S200-S240 are the same as steps S100-S140. Steps S250-S270 are described in detail below.

[0062] S250. If the water quality area is not the preset water quality area, then obtain the usage time corresponding to the water quality area.

[0063] S260. If the usage time is greater than the first preset usage time and less than the second preset usage time, then a prompt code for cleaning the filter screen is displayed, and the prompt code is sent to the application.

[0064] S270. If the usage time is greater than the second preset usage time, the washing machine is controlled to enter the filter cleaning mode and the usage time is reset to zero.

[0065] In this embodiment of the invention, if the water quality area is not a preset water quality area, that is, if the water quality identifier of the water quality area is WQ9, the usage time corresponding to the water quality area is obtained, and it is determined whether the usage time is greater than a first preset usage time; if the usage time is not greater than the first preset usage time, then use continues; if the usage time is greater than the first preset usage time, then it is determined whether the usage time is greater than a second preset usage time; if the usage time is not greater than the second preset usage time, it indicates that the filter screen has a certain degree of dirt blockage, then a prompt code for cleaning the filter screen is displayed, and the prompt code is sent to the application to remind the user to clean it; if the usage time is greater than the second preset usage time, it indicates that the user has not cleaned the filter screen in time, then the washing machine is controlled to enter the filter screen cleaning mode for automatic cleaning, and the usage time is reset to zero.

[0066] Figure 5 This is a flowchart illustrating a filter cleaning reminder method according to another embodiment of the present invention, as shown below. Figure 5 As shown, the method includes steps S300-S390, and steps S300-S370 are the same as steps S200-S270. Steps S380-S390 are described in detail below.

[0067] S380. If the number of uses is not greater than the number of uses threshold, then update the number of uses and obtain the working mode set on the human-computer interaction interface.

[0068] S390, Control the washing machine to enter the working mode.

[0069] In this embodiment of the invention, if the number of uses is not greater than the usage threshold, it indicates that the filter is not severely clogged and does not require cleaning. In this case, the number of uses in the preset storage area is updated by incrementing the number of uses by 1, and the working mode set on the human-machine interface is retrieved, for example, the working mode is a quick wash mode, and the washing machine is controlled to enter that working mode. It should be noted that when the number of uses exceeds the usage threshold, a prompt message indicating that the filter needs cleaning will be issued. If the user cleans the filter, the number of uses will be reset to zero. Understandably, if the user does not clean the filter, the number of uses will continue to be updated.
