[0040] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0041] Please see Figure 1 This application provides a washing machine, including a housing 101, a Braille activation device 103, a Braille display device 105, and a controller (not shown). The Braille activation device 103 and the Braille display device 105 are respectively disposed on the outer surface of the housing 101. The Braille activation device 103 and the Braille display device 105 are respectively connected to the controller. The controller is used to respond to the pressing operation of the Braille display device 105 to currently display Braille content, and to control the Braille display device 105 to arrange and display different Braille content.

[0042] Specifically, in this embodiment, the Braille display device 105 has the ability to arrange and display different Braille content under the control of the controller. It is understood that the placement of the Braille activation device 103 and the Braille display device 105 is not unique. In one embodiment, the Braille activation device 103 and the Braille display device 105 can be placed on the same surface of the housing 101, for example, both on the upper surface formed when the washing machine is normally placed. In another embodiment, the Braille activation device 103 and the Braille display device 105 can be placed on different surfaces of the housing 101, depending on actual needs.

[0043] The aforementioned washing machine is equipped with a Braille activation device 103 and a Braille display device 105. Triggering the Braille activation device 103 starts the washing machine, and the Braille display device 105 displays Braille content. Under the control of the controller responding to a press operation on the currently displayed Braille content, different Braille contents can be arranged and displayed. This solution utilizes the Braille display device 105 to switch and display different Braille contents, making it readable for visually impaired individuals and thus making the washing machine suitable for their use.

[0044] The structure of the Braille display device 105 is not unique. In one embodiment, the Braille display device 105 includes a driver, a Braille arrangement array, and a first pressure detector. The Braille arrangement array is disposed on the first pressure detector, the driver is connected to the Braille arrangement array, and the first pressure detector and the driver are respectively connected to a controller. The driver is used to drive the arrangement structure located at different points in the Braille arrangement array to move in order to display the corresponding Braille content. The first pressure detector is used to detect the user's pressing action on the displayed Braille content.

[0045] Specifically, the Braille array includes an array arrangement structure. Corresponding positions in the Braille display area of ​​the washing machine casing 101 are provided with array through-holes. Each arrangement structure of the Braille display device 105 can extend to the outside of the washing machine through the through-holes under the control of the controller, i.e., to achieve a raised operation; or, under the control of the controller, to retract from the through-holes into the interior of the casing 101, i.e., to achieve a recessed operation. In actual operation, the Braille display device 105 displays different Braille content through the raised positions of the arrangement structures at different locations for the user to read.

[0046] It is understood that, in one embodiment, in order to improve the display efficiency of Braille content, in the Braille content displayed before and after by the Braille display device, only the arrangement structure of the required state at different points is controlled to move during the switching process, while the arrangement structure of the required state at the same points does not need to move during the switching process.

[0047] Specifically, when switching displayed content, if the layout structure of points that need to be raised is already raised before the switch, then the layout structure of these points does not need to be moved and can remain raised. Similarly, if the layout structure of points that need to be recessed is already recessed before the switch, then the layout structure of these points does not need to be moved and can remain recessed.

[0048] The specific type of arrangement structure is not unique. In a more detailed embodiment, the arrangement structure is a columnar structure. One end of the columnar structure is connected to the driver. Under the driving action of the driver, the other end of the columnar structure can extend to the outer surface of the housing 101, thereby arranging and combining to form the corresponding Braille content.

[0049] In one embodiment, the Braille activation device 103 includes a second press detector and a Braille activation button, the Braille activation button being disposed on the second press detector, and the second press detector being connected to a controller.

[0050] Specifically, the Braille start device 103 is equipped with a press detector and a Braille button that displays start / stop (or power on / off, etc.) in Braille form. The Braille button is located on the press detector, which is connected to the controller. When the user presses the Braille button, the button detector detects the press signal and sends it to the controller as an start command.

[0051] It should be noted that, in one embodiment, the washing machine housing 101 is also provided with a display screen 107, which is connected to the controller and is used to display the same content as the Braille display device 105.

[0052] Specifically, in this embodiment, the display screen 107 displays normal graphic information that is the same as the content currently displayed on the Braille display device 105, so as to provide normal visual people with operation guidance for visually impaired people to operate the washing machine, thereby improving the reliability of the washing machine.

[0053] The location of the display screen 107 on the housing 101 is not unique. In one embodiment, it can be located on the same surface of the housing 101 as the Braille display device 105 for easy viewing by the user. More specifically, in one embodiment, the display screen 107 and the Braille display device 105 can be arranged adjacent to each other.

[0054] Please see Figure 2 A washing machine control method includes steps 202, 204 and 206.

[0055] Step 202: If an opening command is received when the Braille start device of the washing machine is triggered, control the washing machine to power on.

[0056] Specifically, the Braille start device is a function button that displays the start task via Braille. When a user needs to use the washing machine, they first need to locate the Braille start device and activate it by pressing it. After activation, the Braille start device sends an activation command to the connected controller. Upon receiving the activation command, the controller powers on the washing machine, putting all its components into standby mode so that the washing operation can begin at any time.

[0057] It should be noted that the specific type of Braille activation device is not unique. Depending on the triggering method of the Braille activation device, the specific structure of the Braille display device will also differ. For ease of understanding, this example uses a press-triggered Braille activation device. In this embodiment, the Braille activation device is equipped with a press detector and a Braille button displaying "Start / Stop" (or "Power On / Power Off," etc.) in Braille format. This Braille button is located on the press detector, which is connected to the controller. When the user presses the Braille button, the button detector detects the press signal and sends it to the controller as an activation command.

[0058] Step 204: If the washing machine is successfully powered on, send a task display command to the Braille display device of the washing machine.

[0059] Specifically, the task display command is used to control the Braille display device to arrange and display Braille washing tasks. The task display command carries the arrangement information of the Braille washing tasks to be displayed by the Braille display device. After receiving the task display command, the Braille display device combines the arrangement information carried in the command to arrange and display the tasks in Braille form. In other words, after the controller successfully powers on the washing machine, it will send a task display command to the Braille display device, enabling the device to display the various washing tasks that the washing machine can perform in Braille for the user to select.

[0060] It should be noted that the specific type of Braille display device is not unique. In a more detailed embodiment, the Braille display device includes a driver, a Braille arrangement array, and a pressure detector. The Braille arrangement array includes an array of arrangement structures. The Braille arrangement array is disposed on the pressure detector, and the driver is connected to the Braille arrangement array. The pressure detector and the driver are respectively connected to a controller. The driver is used to drive the arrangement structures located at different points in the Braille arrangement array to move, so as to display the corresponding Braille content. The pressure detector is used to detect the user's pressing action on the displayed Braille content.

[0061] In actual display, since the washing machine can perform multiple cleaning tasks, in order to enable each cleaning task to be displayed and selected on the Braille display device, in one embodiment, the area for Braille display can be divided into multiple areas, and each area is equipped with a corresponding press detector. During display, each area displays a Braille cleaning task. In actual use, the Braille cleaning task selected by the user can be identified by distinguishing the press signals received from different areas.

[0062] Furthermore, since washing machines can perform a large number of washing tasks, and the area of ​​the Braille display device for displaying Braille is limited, it is impossible to display all Braille washing tasks simultaneously in the Braille display area. Therefore, in one embodiment, a page-turning function can be provided for the Braille display device, that is, the user can view and select the actual Braille washing task by pressing the page-turning function button displayed on the Braille display device.

[0063] It is understood that, in one embodiment, the specific type of Braille cleaning task is the same as that of a conventional washing machine, with only the display method differing. For example, it may include at least one of the following: standard wash, quick wash, spin wash, soak wash, gentle wash, mixed wash, antibacterial wash, cotton / linen, down, silk, and drum cleaning.

[0064] Furthermore, in one embodiment, the washing machine casing has arrayed through holes at positions corresponding to the Braille display area. Each arrangement of the Braille display device can extend to the outside of the washing machine through the through holes under the control of the controller, i.e., protruding; or retract into the casing under the control of the controller, i.e., retracting. In actual operation, the Braille display device displays different Braille content through the protrusions of the arrangement at different points for the user to read.

[0065] It is understood that the specific type of arrangement structure is not unique. In a more detailed embodiment, the arrangement structure is a columnar structure. One end of the columnar structure is connected to the driver. Under the driving action of the driver, the other end of the columnar structure can extend to the outer surface of the shell, thereby arranging and combining to form the corresponding Braille content.

[0066] Step 206: If a cleaning confirmation command is received after the Braille cleaning task is selected, control the washing machine to execute the cleaning operation corresponding to the selected Braille cleaning task.

[0067] Specifically, the Braille display device also has a trigger selection function. After the Braille display device displays different Braille cleaning tasks, the user can read the Braille cleaning task and then select the Braille cleaning task required at the moment. The cleaning confirmation instruction is sent to the controller through the Braille display device, and the controller completes the corresponding cleaning task according to the received cleaning confirmation instruction.

[0068] There is no single method for selecting Braille cleaning tasks; please refer to relevant resources. Figure 3 In one embodiment, taking the Braille display device including a press detector as an example, a corresponding press detector can be set for each Braille cleaning task, so that each Braille cleaning task can be pressed to trigger and realize the selection operation. In another embodiment, each Braille cleaning task can also be represented by a corresponding confirmation function button displayed in Braille, and each function button can be equipped with a press detector. During use, the user only needs to press the confirmation function button corresponding to the desired Braille cleaning task to select the cleaning task.

[0069] The aforementioned washing machine control method incorporates a Braille start-up device and a Braille display device. The washing machine can be activated via the Braille start-up device, and then, under the influence of task display commands, the Braille start-up device can display Braille washing tasks. Users simply select the corresponding Braille washing task to control the washing machine and perform the washing operation. This solution, with its Braille start-up device and Braille task display for user selection, is suitable for visually impaired users.

[0070] Please see Figure 4 In one embodiment, step 206 includes steps 402 and 404.

[0071] Step 402: If a selection signal is received after the Braille cleaning task is selected, a subtask display instruction is returned to the Braille display device.

[0072] Step 404: If a cleaning confirmation instruction is received based on the Braille cleaning sub-task, control the washing machine to execute the cleaning operation corresponding to the selected Braille cleaning task.

[0073] Specifically, the subtask display command is used to control the Braille display device to arrange and display the Braille cleaning subtasks corresponding to the selected Braille cleaning task. The subtask display command carries the arrangement information of the Braille cleaning subtasks corresponding to the selected Braille cleaning task. After receiving the subtask display command, the Braille display device combines the arrangement information of the Braille cleaning subtasks carried in the command to arrange and display the subtasks, and finally displays the Braille cleaning subtasks in Braille form.

[0074] In this embodiment, during the actual washing operation of the washing machine, if any Braille washing task is selected, in order to help the user understand the actual washing content of the washing task, and to avoid the user making a mistake or to meet the user's need to reselect, the controller will also control the Braille display device to arrange and display the Braille washing sub-tasks corresponding to the Braille washing task.

[0075] After the controller directs the Braille display device to display the Braille cleaning tasks, it will detect whether it has received a selection signal from the user based on the Braille cleaning tasks, that is, it will detect which Braille cleaning task the user has selected. Once the controller receives a selection signal from the user after selecting any Braille cleaning task, it will switch the display. The controller sends a sub-task display command to the Braille display device. Under the control of the sub-task display command, the Braille display device operates, re-arranges the tasks, and finally switches to displaying the Braille cleaning sub-task.

[0076] The user then reads the Braille cleaning sub-task and analyzes whether the selected cleaning task meets the requirements. If it does, a cleaning confirmation command is sent to the controller via the Braille display device, at which point the selection of the cleaning task is complete. Following the cleaning confirmation command, the controller initiates the cleaning operation and executes the cleaning task corresponding to the selected cleaning job.

[0077] In one embodiment, the Braille cleaning sub-tasks displayed on the Braille display device are only for user reading, serving as a secondary confirmation of the selected Braille cleaning task. The selected Braille cleaning sub-tasks cannot be changed or selected. In another embodiment, the display interface of the Braille display device always displays function buttons such as confirm, return, and cancel in Braille form. If the user confirms that the Braille cleaning task is correct, pressing the confirm function button will return to the cleaning confirmation instruction.

[0078] In another embodiment, the Braille cleaning subtasks displayed on the Braille display device can not only be read by the user, but the user can also select and confirm each Braille cleaning subroutine. That is, among all the Braille cleaning subtasks corresponding to the Braille cleaning task, at least one Braille cleaning subtask can be selected according to actual needs, and then a cleaning confirmation command can be sent back to the controller to realize the selection of the Braille cleaning subtask.

[0079] Please refer to the following: Figure 5 In one embodiment, step 404 includes steps 502 and 504.

[0080] Step 502: Receive a subtask selection signal sent by the Braille display device when at least one Braille cleaning subtask is selected.

[0081] Step 504: If a cleaning confirmation instruction is received from the Braille display device, control the washing machine to perform the cleaning operation of the Braille cleaning sub-task corresponding to the sub-task selection signal.

[0082] Specifically, in this embodiment, each Braille cleaning sub-task in the Braille display device is equipped with a corresponding press detector. After the Braille display device displays the Braille cleaning sub-task, the user can select the required Braille cleaning sub-task for the current cleaning operation based on actual needs. Each time a Braille cleaning sub-task is selected, the Braille display device returns a sub-task selection signal to the controller. After the user completes the selection, they send a cleaning confirmation command to the controller through the confirmation function button displayed on the Braille display device. Finally, the controller executes the cleaning operation according to the Braille cleaning sub-task corresponding to each sub-task selection signal.

[0083] This solution allows for the display of Braille cleaning tasks, as well as corresponding Braille cleaning sub-tasks for users to select, making the cleaning operation more user-friendly and further improving the ease of use of the washing machine.

[0084] In one embodiment, after step 402, the method further includes: if a return instruction or cancellation instruction is received based on the Braille washing subtask, returning to the step of sending a task display instruction to the Braille display device of the washing machine.

[0085] Specifically, in this embodiment, after receiving the selection signal sent after a Braille cleaning task has been selected, the controller further controls the Braille display device to display the corresponding Braille cleaning subroutine. If the user believes that the current Braille cleaning task does not meet the actual needs after reading the Braille cleaning subroutine, they can re-enter the Braille cleaning program display interface by pressing the return or cancel function button displayed in Braille on the Braille display device.

[0086] This solution allows users to re-enter the Braille cleaning program display interface and reselect the Braille cleaning program when the selected program does not meet their needs, further improving the ease of use of the washing machine.

[0087] Please see Figure 6 In one embodiment, after step 206, the method further includes step 602.

[0088] Step 602: If an operating status command is received from the Braille display device, a progress display command is sent to the Braille display device.

[0089] Specifically, the progress display command carries arrangement information related to the washing operation's progress. The progress display command is used to control the Braille display device to arrange and display the washing operation's progress information. The running status command is the command to query the washing machine's current operation progress. During the washing machine's washing task, the user can interact with the Braille display device, using it to return a running status command to the controller. Thus, under the control of the progress display command sent by the controller, the washing operation's progress information is displayed in Braille form.

[0090] In this solution, after the controller controls the washing machine to perform the washing operation, the user can also provide feedback on the operating status through the Braille display device to check the progress of the washing operation. The progress information of the washing operation is displayed on the Braille display device in Braille form, making it easy for the user to understand the real-time operating status of the laundry room.

[0091] It should be noted that the specific content of the progress information is not unique; in one embodiment, it may display the washing sub-task currently being performed by the washing machine. Please refer to [reference needed]. Figure 7 In another embodiment, the remaining or cumulative washing time of the washing machine can be displayed. Furthermore, the currently executing washing sub-task and the remaining (or cumulative) washing time can be displayed simultaneously; no specific limitation is made.

[0092] Please see Figure 8 In one embodiment, the washing machine control method further includes steps 802 and 804.

[0093] Step 802: If door opening information is received, verify whether the washing machine has entered the washing program.

[0094] Step 804: If the washing machine has not entered the washing program, send an opening command to the door lock device of the washing machine.

[0095] Specifically, the washing program refers to the stage where the washing machine starts running and performs washing-related operations upon powering on according to the start command. The washing machine can detect whether it has received door-opening information in real time, whether it is running or in standby mode. If the controller detects door-opening information, it will further verify whether the washing machine has entered the washing program, that is, whether the washing machine has started running according to the start command. If the washing machine has not entered the washing program at this time, it indicates that the door lock device can be opened at will without affecting user safety or the normal operation of the washing machine.

[0096] It should be noted that the specific type of door opening action information is not unique. In one embodiment, it could be action information such as the user pushing or pulling the washing machine door. Accordingly, in this embodiment, a pull detector or a push detector is installed at the washing machine door. When the user pushes or pulls the door, the pull detector or push detector generates a corresponding pull or push force, and sends the pull signal or push signal as door opening action information to the controller.

[0097] Please see Figure 9 In one embodiment, after step 802, the method further includes steps 902 and 904.

[0098] Step 902: If the washing machine enters the washing program, verify whether the washing operation has ended.

[0099] Step 904: If the cleaning operation is not completed, send a cleaning prompt command to the Braille display device.

[0100] Specifically, the cleaning prompt command is used to control the Braille display device to arrange and display Braille cleaning status information. The cleaning prompt command carries arrangement information of the washing machine's cleaning status. In this embodiment, when the controller detects that the washing machine has entered the cleaning program, it needs to further analyze whether the cleaning operation has been completed. If the cleaning operation is not completed, in order to ensure that the clothes are properly cleaned, the controller will send a cleaning prompt command to the Braille display device. Under the action of the cleaning prompt command, the Braille display device controls the protrusion of the arrangement structure at the corresponding position according to the arrangement information it carries, obtains the Braille cleaning status information, and displays it, thereby informing the user that the washing machine cleaning operation is not yet complete and the door cannot be opened.

[0101] Please see Figure 10 In one embodiment, after step 902, the method further includes steps 102 and 104.

[0102] Step 102: If the washing operation has been completed, check whether the washing machine's cleaning drum temperature meets the preset start-up temperature conditions.

[0103] Step 104: If the temperature of the cleaning cylinder does not meet the preset opening temperature condition, send a temperature prompt command to the Braille display device.

[0104] Specifically, the temperature prompt command is used to control the Braille display device to arrange and display Braille temperature status information. The temperature prompt command carries arrangement information of the cleaning drum temperature status. In this embodiment, a temperature detector is installed inside the washing machine's cleaning drum, which can detect the cleaning drum temperature in real time. After the controller analyzes that the washing machine's washing operation has been completed, it needs to further analyze the received cleaning drum temperature to determine whether the cleaning drum temperature meets the preset opening temperature condition. If the cleaning drum temperature does not meet the preset opening temperature condition, a temperature prompt command is output to the Braille display device. Finally, under the action of the temperature prompt command, the Braille display device arranges and displays the Braille temperature status information in Braille form, thereby informing the user that the washing machine cannot be turned on because the cleaning drum temperature does not meet the preset opening temperature condition.

[0105] It should be noted that the type of preset opening temperature condition is not unique. In a more detailed embodiment, the controller may have a temperature threshold stored in the controller. If the temperature of the cleaning cylinder is greater than or equal to the temperature threshold, it is considered that the preset opening temperature condition is not met.

[0106] Please see Figure 11 In one embodiment, after step 102, the method further includes steps 112, 114 and 116.

[0107] Step 112: If the temperature of the cleaning cylinder meets the preset opening temperature condition, verify whether the door opening action information matches the preset door opening action information.

[0108] Step 114: If the door opening action information matches the preset door opening action information, send an opening command to the door lock device.

[0109] Step 116: If the door opening action information does not match the preset door opening action information, control the washing machine to maintain the locked state.

[0110] Specifically, after the controller detects that the cleaning tub temperature meets the preset opening temperature condition, it further verifies the received door opening action information. This involves checking whether the specific content of the door opening action information matches the preset door opening action information. If the door opening action information perfectly matches the preset door opening action information, the condition for opening the washing machine door is ultimately determined to be met, and the controller will send an opening command to the door lock device to unlock it. If the door opening action information does not match the preset door opening action information, it is considered a false trigger, and the door opening action will not be executed; instead, the washing machine door will remain closed, i.e., in a locked state. This solution verifies the door opening action information when the user requests to open the washing machine, ensuring that the door opening action is executed only when the user genuinely needs to open the door, thus improving the operational safety of the washing machine.

[0111] The type of preset door opening action information is not unique. In one embodiment, taking the door opening action information generated by the user pushing and pulling the washing machine door as an example, the preset door opening action information is the push-pull signal generated by the user regularly pushing and pulling the washing machine door. For example, it could be pulling the door repeatedly, pushing the door repeatedly, or alternately pulling and pushing the door, etc., without being limited to any specific type.

[0112] It is understood that in other embodiments, the door opening action information can also be set as a signal generated by the user kicking or pulling the door, etc., depending on the actual needs. Accordingly, the signal generated by the user kicking or pulling the door according to a certain pattern is used as the preset door opening action information, that is, the door is opened when the user kicks or pulls the door according to the preset pattern.

[0113] It should be noted that the specific type of preset door opening action information is not unique. In actual use, the preset door opening action information can be preset and stored in the controller by the user before using the washing machine. The preset door opening action requirement can be changed in real time according to the user's needs.

[0114] In one embodiment, the washing machine further includes a display screen connected to a controller for displaying the same content as the Braille display device. In this embodiment, the controller simultaneously sends control commands suitable for the display screen to the Braille display device, ensuring that the content displayed by the Braille display device is displayed in the same normal text and graphic format. For example, when the Braille display device displays a Braille washing program, the display screen can display the washing program in normal text; when the Braille display device displays progress information in Braille, the display screen displays the progress information in normal text.

[0115] To facilitate understanding of the technical solution of this application, the following detailed embodiments will be used to explain and illustrate this application.

[0116] First, when the user needs to use the washing machine, they press the Braille start device. The controller receives the start command from the Braille start device and powers on the washing machine. After successful power-on, the controller sends a task display command carrying the Braille washing task arrangement information to the Braille display device. The Braille display device then arranges and displays the available Braille washing tasks. The user then selects from the various Braille washing tasks based on their current washing needs, pressing the button to select the desired task and generating a selection signal, which is sent to the controller. The controller, based on the Braille washing task corresponding to the selection signal, generates a subtask display command carrying the arrangement information of the corresponding Braille washing subtasks, and controls the Braille display device to arrange and switch the display of the Braille washing subtasks.

[0117] The user then performs a secondary confirmation based on the displayed Braille cleaning sub-tasks, analyzing whether the currently selected Braille cleaning task meets their needs. If not, the user uses the return or cancel function button displayed on the Braille display device to send a new task display command to the Braille display device, allowing for a re-display and selection of Braille cleaning tasks. If the Braille cleaning task meets the needs, the user selects one of the displayed Braille cleaning sub-tasks. At this point, at least one Braille cleaning sub-task can be selected (e.g., all Braille cleaning sub-tasks can be selected), generating a sub-task selection signal and sending it to the controller. After the Braille cleaning sub-task selection is complete, the user presses the confirmation function button, receiving a cleaning confirmation command from the Braille display device to the controller. Under the action of this command, the controller, based on the received sub-task selection signal, controls the washing machine to execute the Braille cleaning sub-task corresponding to the sub-task selection signal.

[0118] For further reference Figure 12 During the cleaning process, if the user needs to know the cleaning progress, they can press the running status function button displayed on the Braille display device. The Braille display device will then send the running status command to the controller. After receiving the command, the controller will send arrangement information carrying the progress information of the cleaning operation to the Braille display device, so that the Braille display device can arrange and display the progress information of the cleaning operation for the user to view.

[0119] Regardless of whether a washing cycle is in progress, if the controller receives information indicating that the user has pushed, pulled, kicked, or shoved the washing machine door, it will verify whether the opening conditions are met. During this process, the controller first checks if the washing machine has entered a washing program. If it has, it means the washing machine needs to perform washing operations on the stored clothes. If it hasn't entered a washing program, it means the washing machine is idle and the user can open or close the door at any time. In other words, when the washing machine is not in a washing program, the controller sends an opening command to the door lock device to control the opening of the washing machine door.

[0120] If the washing machine has already entered the washing program, it is necessary to further determine whether the washing operation has ended. If the washing operation has not ended, it is necessary to continue the washing operation. At this time, the controller will send a washing prompt command carrying the arrangement information of the washing machine's washing status to the Braille display device, so as to control the Braille display device to arrange and display the Braille washing status information and inform the user of this status.

[0121] If the washing machine has already completed its washing cycle, the door should not be opened directly to ensure user safety. Instead, the system needs to compare the measured drum temperature with a preset temperature threshold to determine if the drum temperature is below the threshold. If the drum temperature is greater than or equal to the preset temperature threshold, opening the door directly would pose a risk of burns to the user. Therefore, the controller will send a sequence of information containing the drum temperature status to the Braille display device. This information will then be displayed in Braille to inform the user why the door cannot be opened.

[0122] If the drum temperature is below the temperature threshold, further analysis is needed to determine whether the door opening action information matches the preset door opening action information. This includes analyzing whether the user pushes or pulls the door according to a preset pattern, or kicks the door according to a preset pattern, etc. The specifics are not limited. If the door opening action information matches the preset door opening action information, an opening command is sent to the washing machine's door lock device; if the door opening action information does not match the preset door opening action information, the door remains closed to avoid accidental triggering.

[0123] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0124] Based on the same inventive concept, this application also provides a washing machine control device for implementing the washing machine control method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more embodiments of the washing machine control device provided below can be found in the limitations of the washing machine control method described above, and will not be repeated here.

[0125] Please see Figure 13 A washing machine control device includes: a start module 132, a task display module 134, and a washing module 136.

[0126] If the start module 132 receives an start command sent when the Braille start device of the washing machine is triggered, it controls the washing machine to power on; if the washing machine is successfully powered on, the task display module 134 sends a task display command to the Braille display device of the washing machine; the task display command is used to control the Braille display device to arrange and display Braille cleaning tasks; if the washing module 136 receives a cleaning confirmation command sent after a Braille cleaning task is selected, it controls the washing machine to execute the cleaning operation corresponding to the selected Braille cleaning task.

[0127] In one embodiment, the cleaning module 136 is further configured to, upon receiving a selection signal sent after a Braille cleaning task has been selected, return a sub-task display instruction to the Braille display device. If it receives a cleaning confirmation instruction based on the Braille cleaning sub-task, it controls the washing machine to execute the cleaning operation corresponding to the selected Braille cleaning task.

[0128] In one embodiment, the cleaning module 136 is further configured to receive a sub-task selection signal sent by the Braille display device when at least one Braille cleaning sub-task is selected; and if a cleaning confirmation instruction is received from the Braille display device, control the washing machine to perform the cleaning operation of the Braille cleaning sub-task corresponding to the sub-task selection signal.

[0129] In one embodiment, the cleaning module 136 is further configured to control the task display module to send a task display instruction to the Braille display device of the washing machine if it receives a return instruction or cancellation instruction based on the feedback of the Braille cleaning subtask.

[0130] Please see Figure 14 In one embodiment, the washing machine control also includes a progress display module 142.

[0133] The door opening control module 152 is used to verify whether the washing machine has entered the washing program if it receives door opening action information; if the washing machine has not entered the washing program, it sends an opening command to the door lock device of the washing machine.

[0134] The door opening control module 152 is also used to verify whether the washing operation has ended if the washing machine enters the washing program; if the washing operation has not ended, it sends a washing prompt command to the Braille display device.

[0135] The door opening control module 152 is also used to check whether the washing drum temperature of the washing machine meets the preset opening temperature condition if the washing operation has ended; if the washing drum temperature does not meet the preset opening temperature condition, it sends a temperature prompt command to the Braille display device.

[0136] The door opening control module 152 is also used to verify whether the door opening action information matches the preset door opening action information if the cleaning drum temperature meets the preset opening temperature conditions; if the door opening action information matches the preset door opening action information, it sends an opening command to the door lock device; if the door opening action information does not match the preset door opening action information, it controls the washing machine to maintain the locked state.
