Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly to a laundry treatment device and a control method thereof. Background Art

[0002] Laundry treatment devices are essential household appliances in people's daily lives, which liberate us from the cumbersome laundry treatment activities. With the development of technology, laundry treatment devices are also developing towards a more intelligent direction.

[0003] At present, most of the laundry treatment devices on the market require users to walk up to the laundry treatment device and manually turn it on, set the laundry treatment parameters on the panel of the laundry treatment device according to their own preferences and needs, or search for the stored historical data on the panel. Such operation steps are relatively complex, not convenient and intelligent enough, and affect the user experience. Summary of the Invention

[0004] The present application provides a laundry treatment device and a control method thereof, particularly relating to the technical field of household appliances. A locator can be set in the laundry treatment device to detect the distance of the user and verify the user, and after the verification is passed, the historical data of the user using the laundry treatment device can be obtained, so that the laundry treatment device can configure corresponding personalized laundry treatment programs for different users.

[0005] To achieve the above object, the present application adopts the following technical solutions:

[0006] In a first aspect, the present application provides a laundry treatment device, including a housing and a drum assembly disposed in the housing. The device further includes:

[0007] A locator disposed in the housing;

[0008] A controller electrically connected to the locator; the controller is configured to:

[0009] Control the locator to verify a first user corresponding to a first terminal device approaching the laundry treatment device;

[0010] When the locator verifies the first user successfully, obtain first data corresponding to the first user; the first data represents the historical data of the first user using the laundry treatment device for laundry treatment;

[0011] Set a laundry treatment program based on the first data.

[0012] The technical solution provided by this application at least brings the following beneficial effects: By setting a locator in the laundry treatment device, the identity of a user approaching the laundry treatment device can be quickly identified or verified, so as to obtain the historical data of the user using the laundry treatment device for laundry treatment according to the user's identity, and set the laundry treatment program according to the historical data, effectively reducing the complexity of the user operating the laundry treatment device, realizing that the laundry treatment device can accurately determine the laundry treatment program without manually adjusting the laundry treatment parameters, and the determined laundry treatment program can also meet the user's needs, thereby improving the user experience of using the laundry treatment device.

[0013] In some embodiments, when the controller of the laundry treatment device controls the locator to verify the identity of the first user corresponding to the first terminal device approaching the laundry treatment device, it may first control the locator to detect the first distance between the first terminal device and the laundry treatment device; then, when the first distance is less than or equal to the first preset distance, control the locator to verify the identity of the first user. In this embodiment, by detecting the distance between the laundry treatment device and the terminal device, the locator can determine whether the user has the intention to use the laundry treatment device.

[0014] In some embodiments, the first terminal device is the terminal device closest to the locator among the multiple terminal devices detected by the locator. In this embodiment, when the locator detects that multiple terminal devices are approaching the laundry treatment device, it respectively detects the distances between the terminal devices and the laundry treatment device, judges the distances, sets the terminal device with the closest distance as the first terminal device, and verifies the user identity information of this device, so as to cope with the scenario of multiple people using, and realize verifying the user identity priority according to the distance.

[0015] In some embodiments, when the controller obtains the first data corresponding to the first user when the locator verifies the first user successfully, it can obtain the first data corresponding to the first user from the cloud through the first terminal device when the locator verifies the first user successfully. In this embodiment, the laundry treatment device itself does not have a WIFI (Wireless Fidelity) module for obtaining data, etc., so the first data corresponding to the first user is obtained from the cloud through the first terminal device. In some other embodiments, the laundry treatment device itself is provided with a WIFI module, so the controller can directly obtain the first data corresponding to the first user from the cloud through the WIFI. It can be seen that multiple ways can be used to obtain the first data of the user.

[0016] In some embodiments, the controller of the laundry treatment device is further configured to: control a locator to detect a second distance between a second user and the laundry treatment device; the second user is a user associated with the locator; when the second distance is less than or equal to a first preset distance and the laundry treatment device is operating, send a prompt message for prompting a safety hazard of the second user to the user who is using the laundry treatment device. In this embodiment, the user associated with the locator is generally a special group of users, such as the elderly and children. Detecting the distance between the operating laundry treatment device and the special group of users, and sending a prompt message for prompting a safety hazard to the user who is using the laundry treatment device when the distance is too close can, to a certain extent, avoid the occurrence of dangerous events, and there is no need to add an extra sensor for detecting special group of users in the laundry treatment device, reducing the design cost.

[0017] In some embodiments, the controller of the laundry treatment device is further configured to: control a locator to detect a third distance between a target object and the laundry treatment device; the target object is an object associated with the locator; when the third distance is less than or equal to a second preset distance, send a prompt message for prompting a safety hazard of the target object to the user who is using the laundry treatment device; the second preset distance is less than the first preset distance. In this embodiment, the target object may be some valuable items or clothes that cannot be washed. Exemplarily, when valuable items that are not wash-resistant accidentally enter the laundry treatment device along with the clothes, the laundry treatment device can promptly remind the user, thus avoiding unnecessary losses, and there is no need to add an extra sensor for detecting the target object in the laundry treatment device, reducing the design cost.

[0018] In some embodiments, when the controller of the laundry treatment device sets a laundry treatment program based on first data, it may also set the laundry treatment program based on first data of a first user and environmental data. The environmental data includes one or more of weather data, water quality data, temperature data, and wind speed data. In this embodiment, the setting of the laundry treatment program is based on the historical data of the first user and environmental data, so as to determine the laundry treatment program from multiple dimensions, making the laundry treatment program more meet the actual needs of the user and realizing the intelligence of the laundry treatment device.

[0019] In some embodiments, when the controller of the laundry treatment device sets a laundry treatment program based on first data of a first user and environmental data, it may also set the laundry treatment program based on first data of the first user, environmental data, and laundry treatment recommendation data. In this embodiment, the setting of the laundry treatment program is based on the historical data of the first user, environmental data, and laundry treatment recommendation data, so as to determine the laundry treatment program from multiple dimensions, making the laundry treatment program more meet the actual needs of the user and realizing the intelligence of the laundry treatment device.

[0020] In some embodiments, the locator of the laundry treatment device may be a locator based on Ultra-WideBand (UWB) positioning technology, such as a UWB module. In this embodiment, the locator based on UWB positioning technology has low power consumption, good multipath resistance, high security, low system complexity, and can achieve centimeter-level real-time positioning, so that the user identity can be recognized more accurately.

[0021] In a second aspect, the present application provides a control method for a laundry treatment device, which can be applied to the laundry treatment device in the first aspect. The method includes: controlling the locator to verify a first user corresponding to a first terminal device close to the laundry treatment device; obtaining first data corresponding to the first user when the locator successfully verifies the first user; the first data represents historical data of the first user using the laundry treatment device for laundry treatment; setting a laundry treatment program based on the first data.

[0022] In a third aspect, the present application provides a controller, including: one or more processors; one or more memories; wherein, the one or more memories are used to store computer program code, and the computer program code includes computer instructions. When the one or more processors execute the computer instructions, the controller executes the control method for the laundry treatment device provided in the second aspect and possible implementation manners.

[0023] In a fourth aspect, the present application provides a computer-readable storage medium, which includes computer instructions. When the computer instructions run on a computer, the computer is caused to execute the control method for the laundry treatment device provided in the second aspect and possible implementation manners.

[0024] In a fifth aspect, an embodiment of the present invention provides a computer program product, which can be directly loaded into a memory and contains software code. After being loaded and executed by a computer, the computer program product can implement the control method for the laundry treatment device provided in the second aspect and possible implementation manners.

[0025] It should be noted that the above computer instructions may be stored in whole or in part on a computer-readable storage medium. Wherein, the computer-readable storage medium may be packaged together with the processor of the controller, or packaged separately from the processor of the controller. The present application does not make any limitation in this regard.

[0026] For the beneficial effects described in the second to fifth aspects of the present application, reference may be made to the analysis of the beneficial effects in the first aspect, which will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0039] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0040] In the description of this application, it should be noted that, unless otherwise clearly defined and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. Additionally, when describing pipelines, the terms "connected" and "coupled" used in this application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.

[0041] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0042] In the related art, when using a laundry treatment device, the user needs to walk up to the laundry treatment device and manually turn it on, set laundry treatment parameters on the panel of the laundry treatment device according to their preferences and needs, or search for stored historical data on the panel. Such operation steps are relatively complex, not convenient and intelligent enough, affecting the user experience, and unable to flexibly handle the scenario of multiple people using the laundry treatment device.

[0043] Based on the above, the embodiments of this application provide a laundry treatment device. The laundry treatment device is provided with a locator. Through the locator, the identity of the user approaching the laundry treatment device can be quickly recognized. Then, historical data of the user using the laundry treatment device for laundry treatment can be obtained according to the user's identity, and a laundry treatment program can be set according to the historical data. This effectively reduces the complexity of the user operating the laundry treatment device, enables the laundry treatment device to accurately determine the laundry treatment program without manually adjusting the laundry treatment parameters, and the determined laundry treatment program can also meet the user's needs, thereby enhancing the user experience of the laundry treatment device.

[0044] As Figure 1 shown, the laundry treatment device 100 may include: a housing 101, a washing tub 102, a locator 103, and a display 104. Among them, the washing tub 102 and the locator 103 are arranged in the cabinet 101.

[0045] In some embodiments, the washing tub 102 can be used to hold clothes. Exemplarily, when the laundry treatment device 100 is a drum laundry treatment device, the washing tub 102 of the laundry treatment device may include a tub assembly, i.e., an inner tub and an outer tub.

[0046] In some embodiments, the locator 103 is used to obtain the user's location and verify the user's identity. The locator 103 can be a locator based on ultra-wideband (UWB) positioning technology, such as a UWB module.

[0047] In some embodiments, the display 104 can be a liquid crystal display, an organic light-emitting diode (OLED) display. The specific type, size, and resolution of the display 104 are not limited. Those skilled in the art can understand that the display 104 can be changed in terms of performance and parameters as needed.

[0048] In some embodiments, the display 104 can be used to display the control panel of the laundry treatment device 100 or other image information. Exemplarily, the laundry treatment device can display the current operating information of the laundry treatment device through the display 104, such as the type of the laundry treatment program, the running duration of the laundry treatment program, the remaining running duration, the washing water consumption, etc.

[0049] Figure 2 An exemplary hardware configuration block diagram of the laundry treatment device 100 in the embodiments of the present application is shown.

[0050] As Figure 2 shown, the laundry treatment device 100 may further include: a controller 105, a timer 106, a memory 107, a voice prompt module 108, a communication module 109, a human-machine interaction module 110, and a power supply 111. The timer 106, the memory 107, the voice prompt module 108, the communication module 109, the human-machine interaction module 110, and the power supply 111 are all connected to the controller 105.

[0051] In some embodiments, the controller 105 refers to a device that can generate operation control signals according to instruction operation codes and timing signals to instruct the laundry treatment device 100 to execute control instructions. Exemplarily, the controller 105 can be a central processing unit (CPU), a general-purpose processor, a network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The controller 105 can also be other devices with processing functions, such as circuits, devices, or software modules, and the embodiments of the present application do not impose any limitations thereon.

[0052] Exemplarily, the controller 105 can control the locator to verify the first user corresponding to the first terminal device near the laundry treatment device 100; when the locator successfully verifies the first user, obtain the first data corresponding to the first user; and set the laundry treatment program based on the first data.

[0053] In some embodiments, the timer 106 is used to provide the current time, and the timer is connected to the controller 105.

[0054] In some embodiments, the memory 107 is used to store application programs and data. The controller 105 executes various functions and data processing processes of the laundry treatment device 100 by running the application programs and data stored in the memory 107. The memory 107 mainly includes a program storage area and a data storage area. Among them, the program storage area can store an operating system and application programs required for at least one function (such as a voice prompt function, an information display function, etc.); the data storage area can store data created when using the laundry treatment device 100 (such as product information of laundry treatment agents, historical usage data of users, such as the number of washes, dehydration speed, pre-wash time, main-wash time, soaking time, water level, detergent value, softener value, washing water temperature, etc.). In addition, the memory 107 can include high-speed random access memory and can also include non-volatile memory, such as disk storage devices, flash memory devices, or other volatile solid-state storage devices, etc.

[0055] In some embodiments, the voice prompt module 108 is connected to the controller 105 and includes at least a voice chip, an audio power amplifier circuit, and a speaker, and is used to issue a voice prompt after the laundry treatment device 100 completes relevant washing or drying work.

[0056] In some embodiments, when a target person approaches the rotating laundry processing device 100, or when a target object falls into the laundry processing device, the voice prompt module 108 gives a voice prompt of an alarm message.

[0057] In some embodiments, the communication module 109 is a component for communicating with external devices or servers according to various communication protocol types. For example: the communication module 109 may include at least one of a wireless communication technology (Wi-Fi) module, a Bluetooth module, a wired Ethernet module, a near field communication (NFC) module, and other network communication protocol chips or near field communication protocol chips, as well as an infrared receiver. The communication module 109 can be used to communicate with other devices or communication networks (such as Ethernet, radio access network (RAN), wireless local area networks (WLAN), etc.). Exemplarily, the communication module 109 is connected to the controller 103, and the controller 103 can communicate with the terminal device through the communication module 109.

[0058] In some embodiments, the human-machine interaction module 110 is used to implement the interaction between the user and the laundry processing device 100. The human-machine interaction module 110 may include one or more of physical buttons, a touch display panel, or a voice recognition module. For example, the user can start the laundry processing device 100 to work through the human-machine interaction module 110, or can set the laundry processing program for the laundry processing device 100 to run through the human-machine interaction module 110.

[0059] In some embodiments, under the control of the controller 105, the power supply 111 can provide power supply support for the laundry processing device 100 with the power input from an external power source.

[0060] Based on the above laundry processing device, as Figure 3 shown, an embodiment of the present application provides a control method for a laundry processing device, and the method includes the following steps:

[0061] S101. The laundry processing device controls the locator to verify a first user corresponding to a first terminal device close to the laundry processing device.

[0062] In some embodiments, the locator is a locator based on ultra-wideband (UWB) positioning technology, such as a UWB module, etc. The UWB module has low power consumption, good anti-multipath effect, high security, low system complexity, and can achieve centimeter-level real-time positioning. As Figure 4As shown, the UWB module may include a direction sensor. Taking the UWB module as the origin of the X-axis, Y-axis, and Z-axis, the X-axis, Y-axis, and Z-axis are perpendicular to each other. Exemplarily, the positive direction of the X-axis can be the southward direction, the positive direction of the Y-axis can be the eastward direction, and the positive direction of the Z-axis can be the direction perpendicular to the horizontal plane and upward. A space rectangular coordinate system can be established, thereby enabling accurate positioning. In the embodiments of the present application, the method of establishing the space rectangular coordinate system is not specifically limited.

[0063] In some embodiments, the clothing treatment device may be a device such as a washing machine or a dryer, and the first terminal device may be an electronic device such as a mobile phone, a laptop computer, a tablet computer, or a smart bracelet.

[0064] In some embodiments, before the clothing treatment device controls the locator to verify the first terminal device close to the clothing treatment device, the distance between the first terminal device and the clothing treatment device may be detected first. Based on this, as Figure 5 shown, the above S101 may include the following steps:

[0065] S1011. The clothing treatment device controls the locator to detect the first distance between the first terminal device and the clothing treatment device.

[0066] Taking the locator of the clothing treatment device as a UWB module as an example, as Figure 6 shown, the clothing treatment device can detect terminal devices A, B, C, and D. Among them, the coordinates of terminal device B are (1, 1, 0.5). The clothing treatment device can obtain the distance between terminal device B and the clothing treatment device as 1.5 meters according to the distance formula between two points in the space rectangular coordinate system.

[0067] S1012. When the first distance is less than or equal to the first preset distance, control the locator to verify the identity of the first user.

[0068] In some embodiments, the first preset distance may be set before the clothing treatment device leaves the factory, or may be set by the user himself / herself. Exemplarily, the first preset distance set by the clothing treatment device when leaving the factory may be 2 meters, 1 meter, etc. In the embodiments of the present application, it is not specifically limited.

[0069] In other embodiments, a first preset range may also be set, that is, the terminal device may be within a range from the clothing treatment device. The first preset range may be a circular area with the clothing treatment device as the center and a preset length as the radius. For example, the preset length may be 2 meters, 1 meter, etc. The first preset range may also be a plurality of columnar areas formed by taking the body of the clothing treatment device as the basic area and extending a certain distance outward along the four sides of the body. In the embodiments of the present application, the first preset range is not specifically limited.

[0070] In some embodiments, the first terminal device is the terminal device closest to the locator among the multiple terminal devices detected by the locator. Exemplarily, among the above Figure 6 there are multiple terminal devices A, B, C, and D. The locator respectively detects the distances between terminal devices A, B, C, and D and the laundry treatment device, and determines the magnitudes of the distances. If the distance between terminal device B and the laundry treatment device is the smallest and within the first preset distance, terminal device B is designated as the first terminal device, the user using this device is the first user, and the identity of the first user is verified.

[0071] In some other embodiments, in different spaces and environments, there is a user remotely controlling the laundry treatment device through a terminal device. The laundry treatment device receives the corresponding signal. However, at the same time, the locator detects that a user is approaching the laundry treatment device and the distance from the user to the laundry treatment device is within the preset range. Then, the laundry treatment device gives priority to the user with the closer distance. Exemplarily, the male host who is working outside the home is controlling the laundry treatment device through an application. At this time, the hostess at home walks in front of the laundry treatment device with a terminal device to prepare to do laundry. When the locator detects that the distance between the hostess and the laundry treatment device is within the preset range, the laundry treatment device gives priority to the hostess with the closer distance, and the male host who is farther away is prompted that there is a user using the laundry treatment device.

[0072] The foregoing embodiments at least bring the following beneficial effects: By detecting the first distance between the first terminal device and the laundry treatment device through the locator, it can be determined whether the user has the intention to use the laundry treatment device, thereby verifying the identity information of the user. This verification method can handle the scenario of multiple people using the laundry treatment device. By obtaining the distances between multiple terminal devices and the laundry treatment device, judging the distances, and verifying the identity of the user with the closest distance, the priority of verifying the user identity can be determined according to the distance.

[0073] S102. When the locator verifies the first user successfully, the laundry treatment device obtains the first data corresponding to the first user.

[0074] Wherein, the first data represents the historical data of the first user using the laundry treatment device for laundry treatment.

[0075] In some embodiments, the first data includes one or more of the number of washes, dehydration speed, pre-wash time, main-wash time, soaking time, water level, detergent value, fabric softener value, and washing water temperature.

[0076] In some embodiments, the terminal device is communicatively connected to the laundry treatment device. For example, it is connected via Bluetooth, connected via a local area network, connected via an application software in the terminal device, etc.

[0077] In some embodiments, a communication module (such as a WIFI module, etc.) is not installed in the laundry treatment device, so that the laundry treatment device cannot directly obtain the first data of the user. Therefore, the first terminal device can obtain the first data corresponding to the user from the cloud, and then transmit the first data to the laundry treatment device. Among them, a large amount of personalized data of different users is stored in the cloud server, and the first terminal device obtains the personalized data of the corresponding user through the user information.

[0078] Taking the terminal device as a mobile phone and the locator as a UWB module as an example, as Figure 7 shown, when the user holds the mobile phone close to the laundry treatment device, the UWB module of the laundry treatment device detects the mobile phone and obtains the distance of the mobile phone. When the distance reaches within the set range (for example, less than or equal to the first preset distance), the UWB module verifies and identifies the user's identity. After the verification is passed, the Bluetooth module of the mobile phone is bound to the laundry treatment device, and the mobile phone obtains the historical data of the user of the mobile phone using the laundry treatment device for laundry through the WIFI module from the cloud server. The mobile phone sends the historical data to the laundry treatment device through the Bluetooth module.

[0079] In some other embodiments, a communication module (such as a WIFI module, etc.) is installed in the laundry treatment device, so that the laundry treatment device can directly obtain the first data corresponding to the first user from the cloud through the communication module. Exemplarily, as Figure 8 shown, the laundry treatment device comes with a WIFI module. When the user's mobile phone terminal approaches the laundry treatment device, the UWB module of the laundry treatment device detects the mobile phone and obtains the distance of the mobile phone. When the distance reaches within the set range (for example, less than or equal to the first preset distance), the UWB module verifies and identifies the user's identity. After the verification is passed, the laundry treatment device obtains the historical data of the user of the mobile phone using the laundry treatment device for laundry through the built-in WIFI module from the cloud server.

[0080] S103. The laundry treatment device sets a laundry treatment program based on the first data.

[0081] In some embodiments, the laundry treatment parameters included in the laundry treatment program include one or more of the number of washing times, dehydration speed, pre-washing time, main-washing time, soaking time, water level height, detergent value, softener value, and washing water temperature. Among them, one or more of the above laundry treatment parameters may be different for different laundry treatment programs.

[0082] In addition, the laundry treatment program may further include different washing modes, such as a disinfection wash mode, an air wash mode, a detergent-free wash mode, etc. Under different washing modules, one or more of the above laundry treatment parameters may be different.

[0083] In some embodiments, the settings of the laundry treatment program can also be based on environmental data, where the environmental data includes one or more of weather data, water quality data, temperature data, and wind speed data. For example, the acquisition of environmental data can be achieved by connecting the built-in WIFI module in the laundry treatment device to the network, locating the location of the laundry treatment device through the network, and then obtaining the environmental data of the location of the laundry treatment device from the server, or by using a terminal device to locate the location of the laundry treatment device and obtaining the environmental data of the location of the laundry treatment device.

[0084] Exemplarily, different environmental data corresponds to different evaporation rates. The evaporation rate of the moisture of the laundry in a wet state per unit time can be obtained from the environmental data. When the evaporation rate of the moisture of the laundry is low, it is preferred to fully dehydrate the laundry. When the evaporation rate of the moisture of the laundry is high, it is preferred to appropriately reduce the amount of dehydration of the laundry, such as reducing the dehydration time or the dehydration rotation speed, thereby saving electric energy. This embodiment fully considers the influence of environmental data on the laundry treatment parameters, thereby improving the matching degree between the environmental data and the laundry treatment parameters and saving electric energy.

[0085] In some other embodiments, the settings of the laundry treatment program can also be based on the laundry treatment programs recommended by nearby users. For example, the terminal device obtains the laundry treatment programs recommended by users in this area through the cloud server and uses the laundry treatment program with the highest user usage frequency as a reference program.

[0086] In some other embodiments, the settings of the laundry treatment program can also be based on data such as the category, material, and weight of the current laundry. Exemplarily, when the laundry material is not easy to be dehydrated at a high speed, the maximum rotation speed corresponding to the laundry material is obtained, the dehydration rotation speed is adjusted to be less than the maximum rotation speed of the laundry material, and the dehydration rotation speed is further adjusted according to the environmental data so that the final dehydration rotation speed matches the laundry material and also matches the environmental data at the same time.

[0087] In some embodiments, after the user uses the laundry treatment device, the generated laundry treatment program can also be stored in the laundry treatment device or uploaded to the cloud server for the user to use next time.

[0088] The foregoing embodiments at least bring the following beneficial effects: By setting a locator in the laundry treatment device, the identity of a user approaching the laundry treatment device can be quickly identified or verified, so as to obtain historical data of the user using the laundry treatment device for laundry treatment according to the user's identity, and set a laundry treatment program according to the historical data, effectively reducing the complexity of the user operating the laundry treatment device, realizing that the laundry treatment device can accurately determine the laundry treatment program without manually adjusting the laundry treatment parameters, and the determined laundry treatment program can also meet the user's needs, thereby enhancing the user experience of using the laundry treatment device.

[0089] In some embodiments, as Figure 9 shown, the method may further include the following steps:

[0090] S201. The laundry treatment device controls the locator to detect a second distance between a second user and the laundry treatment device. Wherein, the second user is a user associated with the locator.

[0091] In some embodiments, the user associated with the locator is generally a special group user, such as an elderly person or a child.

[0092] S202. When the second distance is less than or equal to a first preset distance and the laundry treatment device is running, a prompt message for prompting the user using the laundry treatment device that there is a safety hazard of the second user is sent to the user.

[0093] In some embodiments, the laundry treatment device may also be configured with a locking function, and when it is detected that the distance between the second user and the laundry treatment device is too close, the laundry treatment device can be locked.

[0094] In other embodiments, when it is detected that the distance between the second user and the laundry treatment device is too close, the laundry treatment device may also stop running. Wherein, the laundry treatment device stopping running may be that the laundry treatment device is directly in a shutdown state, or the laundry treatment device stops the current running state.

[0095] In some embodiments, the prompt message may be to send a text prompt message to the user using the laundry treatment device, or a voice prompt message. When the prompt message is a voice prompt message, the terminal device may send a voice prompt to the user: "There is a special person approaching the running device. To avoid dangerous situations, please handle the relevant situation in time." When the first prompt message is a text prompt message, the terminal device displays the text prompt "There is a special person approaching the running device. To avoid dangerous situations, please handle the relevant situation in time."

[0096] In some embodiments, the laundry treatment device may also send a prompt message, which may be a text prompt, a voice prompt, etc., or may just be a music prompt or a beeping prompt, and the music prompt can be set by the user independently.

[0097] Taking the locator of the laundry treatment device as a UWB module as an example, a UWB tag paired, associated or matched with the UWB module can be attached to a special group such as a child or an elderly person. Thus, when they approach the laundry treatment device rotating at a high speed, the UWB module detects that the distance between the child or the elderly person and the laundry treatment device is within a set range (for example, less than or equal to a first preset distance), the laundry treatment device will stop its current operating state, emit a beeping prompt, and send a voice prompt such as "A special person is approaching the operating device, please handle the relevant situation in time" to the user who is using the laundry treatment device. Exemplarily, if the first preset distance is 2 meters, a child wearing an electronic watch with a UWB tag walks towards the operating laundry treatment device. When the UWB module detects that the distance between the child and the laundry treatment device is less than or equal to 2 meters, the laundry treatment device immediately stops its current operating state, emits a beeping prompt, and sends a voice prompt "A child is approaching the laundry treatment device, which is prone to danger. Please pay attention in time" to the user who is using the laundry treatment device.

[0098] The foregoing embodiments at least bring the following beneficial effects: By detecting the distance between the operating laundry treatment device and the special group of users, and sending a prompt message for prompting the existence of potential safety hazards to the user who is using the laundry treatment device when the distance is too close, dangerous events can be avoided to a certain extent, and there is no need to add an extra sensor for detecting special group of users in the laundry treatment device, reducing the design cost.

[0099] In some embodiments, as Figure 10 shown, the method may further include the following steps:

[0100] S301. The laundry treatment device controls the locator to detect a third distance between the target object and the laundry treatment device. Wherein, the target object is an object associated with the locator.

[0101] In some embodiments, the target object is a valuable item or a piece of clothing that cannot be washed.

[0102] S302. When the third distance is less than or equal to a second preset distance, send a prompt message for prompting the existence of potential safety hazards of the target object to the user who is using the laundry treatment device; the second preset distance is less than the first preset distance.

[0103] Wherein, the second preset distance is less than the first preset distance.

[0104] Specifically, the second preset distance refers to another preset distance value of the laundry treatment device. When the distance between the target and the laundry treatment device is less than or equal to this distance value, the laundry treatment device will send a prompt message to the user who is using the laundry treatment device to prompt that there is a potential safety hazard with the target object.

[0105] In some embodiments, the second preset distance can be set before the laundry treatment device leaves the factory, or can be set by the user himself. Exemplarily, the second preset distance set by the factory for the laundry treatment device is 0.5 meters.

[0106] In some embodiments, the prompt message can be to send a text prompt message to the user who is using the laundry treatment device, or can be a voice prompt message. When the prompt message is a voice prompt message, the terminal device can send a voice prompt to the user: "There is a target object falling into the laundry treatment device. Please handle the relevant situation in time." When the first prompt message is a text prompt message, the terminal device displays the text prompt: "There is a target object falling into the laundry treatment device. Please handle the relevant situation in time."

[0107] In some other embodiments, the laundry treatment device can also send a prompt message. The prompt message can be a text prompt, a voice prompt, or just a music prompt or a beeping sound prompt, and the music prompt can be set independently by the user.

[0108] In some embodiments, taking the locator of the laundry treatment device as a UWB module as an example, a UWB tag paired, associated or matched with the UWB module can be attached to the valuable item. When the valuable item is placed in the pocket of the clothes to be washed and falls into the laundry treatment device along with the clothes, the locator can detect this situation in time, emit a beeping sound prompt, and send a voice prompt to the user who is using the laundry treatment device: "There is a target object falling into the laundry treatment device. Please handle the relevant situation in time." Exemplarily, the second preset distance is 0.1 meter. When the necklace with the UWB tag falls into the laundry treatment device, the UWB module detects that the distance between the necklace and the laundry treatment device is less than 0.1 meter, and the laundry treatment device emits a beeping sound prompt and sends a voice prompt to the user who is using the laundry treatment device: "There is a necklace falling into the laundry treatment device. Please handle the relevant situation in time."

[0109] The foregoing embodiments at least bring the following beneficial effects: By detecting the distance between the laundry treatment device and the target object, and sending a prompt message to the user who is using the laundry treatment device to prompt the existence of a safety hazard when the distance is too close, unnecessary losses can be avoided to a certain extent, and there is no need to add an extra sensor for detecting the target object in the laundry treatment device, reducing the design cost.

[0110] In some embodiments, there are multiple laundry treatment devices in a household. The multiple UWB modules in the multiple laundry treatment devices can form a two-dimensional or even three-dimensional space. When there are a large number of clothes, the user can implement the function of copying and pasting laundry treatment programs through a mobile terminal. Specifically, when aligning with or approaching a running laundry treatment device, the laundry treatment program can be copied, and when aligning with or approaching a non-running laundry treatment device, the laundry treatment program can be pasted, thus saving the cumbersome steps of repeatedly setting laundry treatment programs, realizing the convenient and intelligent program setting, and enhancing the user experience of using laundry treatment devices.
