Description

Technical Field

[0001] This invention belongs to the field of intelligent washing machine technology, and particularly relates to a two-way linkage multi-drum washing machine interactive control method and a multi-drum washing machine. Background Technology

[0002] With the development of smart home technology and the increasing demand for refined clothing care, laundry equipment is gradually evolving from traditional single-drum washing structures to multi-functional, multi-unit collaborative control systems. Multi-drum laundry equipment, such as twin-drum washing machines and twin-drum washer-dryers, can handle different types of clothing—materials, colors, and care requirements—by setting up multiple independent washing units, thus meeting users' needs for categorized washing. Existing multi-drum washing equipment typically uses a single display screen as the human-machine interface, with the control system enabling program selection, parameter settings, and status display for different washing drums. Compared to the traditional method of controlling multiple devices separately, this reduces the space occupied by the equipment and improves overall ease of use.

[0003] Currently, various technical solutions have been proposed for human-machine interaction control of multi-drum washing machines. For example, patent CN106032625A discloses a washing machine and its control method. This solution uses a touch screen display and multiple independent washing units, and utilizes the touch screen to display the control menus corresponding to different washing units in a split-screen manner. It also uses switching icons to switch between the control interfaces of different washing units, allowing users to control multiple washing units through a unified display interface. This type of technical solution reduces the need for multiple control panels through centralized display control, improving the integration level of multi-drum washing machines.

[0004] Furthermore, to reduce the number of steps users need to take to switch between different washing drums, existing technologies have proposed multi-drum control methods based on quick operation. For example, patent CN121593267A discloses a control method for a multi-drum washing machine. This solution responds to quick operations for another washing drum within the designated area of ​​the current washing drum control interface, allowing users to perform some control operations without fully accessing the control interface of another washing drum. This reduces the number of interface switches and improves the operating efficiency of multi-drum washing equipment. These solutions primarily optimize the operation flow at the control interface level, enabling users to control different washing drums more quickly.

[0005] Furthermore, to enhance the intelligent user experience, some existing technologies have begun to link the status of the washing drum door with the display interface control. For example, patent CN117762359A discloses a screen display control method for a multi-drum garment care device. This solution detects the opening and closing signal of the care unit door and controls the screen to display the corresponding care unit's interface based on the detection result. This allows the user to automatically enter the corresponding control page after opening the corresponding drum door, thereby reducing the need for manual selection of the washing drum. This type of technical solution realizes the information association between the washing drum door action and the display interface, providing a more convenient control method for human-machine interaction in multi-drum devices.

[0006] However, existing human-machine interface control methods for multi-drum washing machines primarily focus on optimizing display interface switching, program information display, and simplified operation paths. Their control logic typically relies on the user actively selecting the corresponding washing drum via the touchscreen or manually operating the drum door to trigger interface changes. Users still need to confirm the interaction between the display interface and the actual washing drum, resulting in a certain operational burden in actual use. Especially when a user needs to open a particular washing drum to load or unload clothes, current technology usually requires the user to first complete the screen selection or confirmation operation, then move to the corresponding location to manually open the drum door, or wait for the display interface to change synchronously after opening the drum door. The overall operation process still suffers from unnatural step transitions.

[0007] Meanwhile, existing technologies that associate door status with the display interface primarily adjust the display content based on the door's opening status, constituting auxiliary control for the display interface. They do not fully consider the collaborative relationship between display control and door movement. In actual use of multi-drum washing equipment, due to differences in upper and lower drum positions, user operating habits, and spatial distance between the display interface and the physical structure, users may select a drum on the display but still need to locate and open the corresponding door during actual operation. This increases the number of steps required for user operation and reduces the continuity of the human-machine interaction process.

[0008] In addition, when switching between multiple washing drums in existing multi-drum washing equipment, there is a lack of further correlation constraints between the status of the display interface and the actual status of the drum door. When the user operates different washing drums continuously, there may be a problem that the washing drum corresponding to the display interface is inconsistent with the actual object operated by the user, which requires the user to repeatedly confirm the current controlled object and affects the intuitiveness of operation.

[0009] Therefore, how to further optimize the human-machine interaction control method of multi-drum washing equipment and improve the user's operational convenience and the level of equipment intelligence remains a technical problem that needs to be solved in the current twin-drum washing machine field. Summary of the Invention

[0010] This invention aims to solve the problems in existing multi-drum washing machines where the operation of the physical drum door and the display interaction are independent. Users need to manually switch the target drum control interface and repeatedly perform the door opening operation, resulting in cumbersome operation, discontinuous interactive response, and a lack of synchronization between the door status and the display interface. This application establishes a two-way linkage control relationship between the door status and the display interface, allowing users to trigger the display interface switch through the door opening action or drive the corresponding drum door to open through screen selection. This achieves closed-loop control between physical operation and digital interaction, improving the ease of operation and intelligence of multi-drum washing machines.

[0011] The technical solution of the present invention is as follows: The first objective of this application is to disclose a two-way interactive control method for a multi-drum washing machine, including: Obtain the door status information corresponding to multiple drums in a multi-drum washing machine; The target cylinder currently being operated by the user is determined based on the door status information, and the display device is controlled to switch to the control interface corresponding to the target cylinder. When a change in the door status is detected, a first control command is generated based on the corresponding door status information to control the display device to display the control interface of the corresponding cylinder, so that a first directional linkage relationship is formed between the change in door status and the switching of the display interface.

[0012] Preferably, obtaining the door status information corresponding to multiple cylinders includes: The door status detection components installed at each cylinder door acquire the opening status, closing status, or opening / closing change status of the corresponding door, and send the door status information to the controller to determine the target cylinder currently being operated by the user.

[0013] Preferably, when the door corresponding to any cylinder is detected to switch from a closed state to an open state, the controller generates an interface switching command based on the corresponding door status information and controls the display device to switch to the control interface corresponding to that cylinder.

[0014] Preferably, the cylinder selection operation information received by the display device is acquired; The target cylinder selected by the user is determined based on the cylinder selection operation information, and the door corresponding to the target cylinder is controlled to perform an opening action. When the user selects a target cylinder through the display device, a second control command is generated based on the cylinder selection operation information to control the door of the corresponding cylinder to perform an opening action, so that a second directional linkage relationship is formed between the cylinder selection operation in the display device and the corresponding door opening action.

[0015] Preferably, the cylinder selection operation information includes cylinder selection information input by the user through the display device. The controller determines the target cylinder based on the cylinder selection information and determines whether the door corresponding to the target cylinder meets the preset opening conditions. When the preset opening conditions are met, the controller controls the door corresponding to the target cylinder to perform an automatic opening action.

[0016] Preferably, the door opening conditions include the target cylinder being in a non-operating state, the corresponding door lock of the target cylinder being in an unlocked state, and no equipment malfunction being detected. When the controller determines the target cylinder based on the cylinder selection operation information, if the target cylinder meets the door opening conditions, the controller controls the corresponding door drive component to release the door lock state and drives the door corresponding to the target cylinder to open at a preset angle so that the user can continue to perform the operation of putting in or taking out clothes. If the door opening conditions are not met, the controller stops outputting the door opening command and outputs corresponding prompt information through the display device.

[0017] Preferably, the multi-drum washing machine includes at least a first drum and a second drum. When the display device is currently displaying the control interface corresponding to the first drum, if it detects that the door corresponding to the second drum has switched to an open state, the controller updates the current target drum according to the door status information output by the door status detection component corresponding to the second drum, and controls the display device to switch from the control interface corresponding to the first drum to the control interface corresponding to the second drum. When the display device is currently displaying the control interface corresponding to the second drum, if it detects that the door corresponding to the first drum has switched to an open state, the controller updates the current target drum according to the door status information output by the door status detection component corresponding to the first drum, and controls the display device to switch to the control interface corresponding to the first drum.

[0018] Preferably, when multiple cylinders are detected to have doors that are open at the same time, the controller obtains the time stamp corresponding to the status change information of each door, determines the current target cylinder based on the status change time of each door, identifies the cylinder whose door status last changed as the target cylinder, controls the display device to switch the display to the control interface corresponding to the target cylinder, and generates corresponding status prompt information.

[0019] Preferably, after the door corresponding to the target cylinder is opened, user operation information and cylinder status information within a preset time are obtained. When no clothing is detected being placed or no operation status is displayed, the corresponding door is controlled to perform a closing action.

[0020] Preferably, during the process of controlling the door to close, obstacle detection information around the door is acquired. When an obstacle is detected, the door closing action is stopped, and the door is controlled to perform a reversing action.

[0021] Preferably, after the door corresponding to the target cylinder is opened, the controller controls the display device to switch to the program selection interface corresponding to the target cylinder, and switches to the corresponding parameter configuration interface after the user selects a program. Alternatively, the controller determines a recommended program from the program set corresponding to the target cylinder and displays the recommended program in the program selection interface first.

[0022] Preferably, the multi-drum washing machine has a capacitive proximity sensor at the drum door handle. The capacitive proximity sensor detects the proximity signal generated when the user's hand approaches the target drum door handle and sends the proximity signal to the controller. The controller determines the corresponding target drum based on the proximity signal and, after detecting the proximity signal, preloads the program selection interface, parameter configuration interface, and interface resource data corresponding to the target drum into the display device's cache area. When the corresponding drum door opening signal is detected, the controller controls the display device to call the cached interface resources and switch to the control interface corresponding to the target drum.

[0023] Preferably, the control method further includes a voice control step, in which the user's cylinder selection command is acquired through a voice acquisition module, and the voice information is recognized and processed to determine the target cylinder. The controller controls the door drive component of the corresponding cylinder to perform the door opening action according to the recognition result, and at the same time controls the display device to switch to the control interface corresponding to the target cylinder, so as to realize the synchronous linkage control of cylinder selection, door opening and interactive interface based on voice command.

[0024] The second objective of this application is to disclose a two-way interconnected multi-drum washing machine, comprising: The body contains multiple independent cylindrical sections. The door assembly includes multiple door bodies respectively disposed corresponding to the multiple cylindrical bodies; The display device is used to receive user input for cylinder selection and display a control interface that matches the corresponding cylinder. A door status detection component is used to detect the status information of each door. The door drive assembly is used to drive the corresponding door to perform opening or closing actions according to control commands. The controller is connected to the display device, the door status detection component, and the door drive component, respectively. It is used to control the display device to switch to the corresponding cylinder control interface according to the door status information obtained by the door status detection component, and to control the corresponding door to perform an opening action according to the cylinder selection operation received by the display device, so as to form a two-way linkage control between the door status change and the display interface change.

[0025] Preferably, the cylindrical body includes a first cylindrical body and a second cylindrical body arranged vertically, the door body includes a first cylindrical door and a second cylindrical door respectively disposed on the first cylindrical body and the second cylindrical body, and the display device is disposed between the first cylindrical body and the second cylindrical body.

[0026] Compared with existing technologies, the bidirectional linkage multi-drum washing machine interactive control method and multi-drum washing machine described in this invention have the following advantages: 1. This application effectively solves the problem in traditional multi-drum washing machines where users need to actively search for the corresponding control interface by establishing a linkage control relationship between the door status and the display interface. When a user directly opens a drum door, the controller can quickly identify the current operation target based on the information fed back by the door status detection component and control the display device to automatically switch to the corresponding drum control interface. This allows the user's actual operation to directly trigger changes in the display interface, realizing a natural physical-to-digital interaction. This method uses the physical operation already completed by the user as the basis for target identification, reducing the steps of observing the drum position, returning to the screen to search, and repeating selections. This makes the washing machine control process more in line with user habits and avoids the problem that users cannot quickly confirm the current control object due to the multi-drum structure, improving the intuitiveness and operational efficiency of the equipment.

[0027] 2. This application further establishes a correlation control relationship between display operation and door movement, enabling users to actively select the target drum through the display device, and the controller to automatically open the corresponding door, realizing a reverse linkage between digital and physical components. Compared with the traditional washing machine where the display interface is only used to display information and receive parameter settings, this application enables the display device to actively control the movement of the physical structure, allowing users to complete continuous operations such as drum selection, interface switching, and door opening on the screen. This reduces the process of users moving to the corresponding drum door position and manually opening the door, which is especially suitable for use scenarios with a bottom-mounted drum or when users are carrying clothes with both hands. At the same time, it reduces the operation difficulty for elderly users or users with mobility difficulties and improves the human-machine interaction convenience of multi-drum washing machines.

[0028] 3. This application uses a controller to uniformly process door status detection signals, user input signals, and door drive signals, ensuring that different operation methods are executed based on the same control logic. Combined with target drum recognition, interlock control, safety detection, and anti-pinch protection mechanisms, the system maintains consistency between the displayed state, door state, and user operation intentions. When the user changes the operating object or multiple drums are operated simultaneously, the controller can update the target drum based on the latest operation information, avoiding mismatches between the displayed interface and the actual operating object. Furthermore, by setting automatic door closing and anti-pinch detection functions, the automatic door control process is made safer and more reliable. Therefore, this application not only improves the intelligence level of the multi-drum washing machine interaction process but also provides a unified control foundation for subsequent program recommendations, voice control, and intelligent scene expansion.

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0031] It should be noted that all directional and positional terms used in this invention, such as "up," "down," "left," "right," "front," "back," "vertical," "horizontal," "inner," "outer," "top," "lower," "lateral," "longitudinal," and "center," are only used to explain the relative positional relationships and connections between components in a specific state (as shown in the accompanying drawings). They are merely for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. Furthermore, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0032] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] To address the issue of inconsistent human-machine interaction in the multi-drum interactive control process of existing multi-drum washing machines, current technologies typically only implement a one-way response mode based on changes in the display interface triggered by the user's physical operation. For example, after a user opens the door of a certain drum, selects the corresponding drum on the display screen, and then manually performs the door opening operation, the above interaction process is essentially still a "passive response" mode. That is, the screen display always needs to passively switch according to the user's physical operation (such as clicking the screen or opening the door), and has not yet achieved reverse active control from the "digital end" (screen selection) to the "physical end" (automatic door opening). Even if the user selects a drum on the screen, they still need to manually bend down to open the door, failing to completely free the user's hands. This operational burden still exists, especially for elderly users or those with mobility difficulties. At the same time, there is only a one-way mapping between opening the door and switching the screen, without forming a complete interactive loop. During use, users may still experience cognitive confusion and misoperation due to the misalignment between "the screen displaying the current drum" and "actually opening the door of another drum".

[0035] Therefore, this application proposes a two-way linkage interactive control method for multi-drum washing machines. By establishing a two-way association control mechanism between the display interface and the washing drum door, changes in the door's state can actively trigger the switching of the display interface. At the same time, the washing drum selection operation on the display interface can reversely control the corresponding door to perform an automatic opening action. This achieves a two-way interactive closed loop consisting of "door operation driving interface response" and "interface selection driving physical action." Regardless of whether the user starts operating from the physical end or the digital end, the system can automatically recognize the user's current control intention and synchronously adjust the corresponding display state and equipment action. This effectively reduces the user's operation steps and improves the human-machine interaction convenience, intelligence level, and user experience of the multi-drum washing machine.

[0036] Specifically, such as Figure 1 As shown, this application discloses a bidirectional linkage interactive control method for a multi-drum washing machine, including: Obtain door status information and user interaction operation information corresponding to different drums in a multi-drum washing machine; The target cylinder currently being operated by the user is determined based on the door status information, and the display device is controlled to switch to the control interface corresponding to the target cylinder. The target cylinder is determined based on the user's cylinder selection operation on the display device, and the door corresponding to the target cylinder is controlled to perform an opening action; The first-direction linkage relationship is formed between the door state change of the multi-drum washing machine and the display interface switching, and the second-direction linkage relationship is formed between the drum selection operation in the display device and the corresponding door opening action, so that the user can realize the automatic matching of the drum control object and the corresponding door state adjustment through door operation or display operation.

[0037] This application provides a bidirectional linkage interactive control method for a multi-drum washing machine. This method establishes a bidirectional correlation control relationship between the washing machine door status information and the display device operation information to achieve automatic matching between user operation behavior and washing machine response actions. The interactive control method includes: acquiring door status information corresponding to different drums in the multi-drum washing machine and the user's drum selection operation information on the display device through a controller; determining the target drum currently being operated by the user based on the door status information; and controlling the display device to switch to the control interface corresponding to the target drum. Simultaneously, based on the user's drum selection operation information on the display device, determining the user's desired operation... The system uses a target cylinder and controls the corresponding door to open, creating a first-direction linkage between door state changes and display interface switching. It also creates a second-direction linkage between cylinder selection on the display device and the corresponding door opening action. During the door state triggering display interface switching, door detection devices located at each cylinder door position continuously monitor the opening or closing status of the corresponding door and send the detected door state information to the controller. When a user directly opens a cylinder door, the controller determines the target cylinder the user needs based on the corresponding door's state change information and controls the display device to automatically enter that target cylinder. The control interface corresponding to the target cylinder allows users to perform program selection, parameter adjustment, or operation control without manually searching for the corresponding cylinder interface after the door is opened. During door opening control via the display interface, when the user selects a target cylinder through the display device, the controller determines the corresponding cylinder based on the user's input and sends a control command to the corresponding door drive component. This causes the door drive component to automatically open the corresponding door, eliminating the need for the user to manually move to the cylinder position after completing the screen selection. In the bidirectional linkage control process, the controller continuously acquires door status information and display operation information, and adjusts the control based on the user's latest... The generated operational behavior determines the current controlled object. When the user continuously operates different cylinders, the controller updates the target cylinder based on the latest detected door change information or display selection information, and synchronously adjusts the display interface state to ensure that the control interface displayed on the display device is always consistent with the cylinder actually operated by the user. This avoids the problem of the displayed object not corresponding to the actual operated object due to changes in the operation sequence. At the same time, the controller can also manage the door state based on the door opening time, the user's subsequent operation state, and the equipment operating state. When no subsequent operation is detected after the door is automatically opened, the door state is adjusted accordingly to improve the safety and stability of the equipment during use.

[0038] Through the above control method, users can achieve automatic matching of the display interface through actual door operation, and can also achieve corresponding door action control through the display interface selection. This creates a two-way collaborative relationship between the display control and the drum structure. Compared with the existing control methods that only switch drums through the touch screen or only adjust the display content according to the door status, this application can automatically complete drum recognition, interface switching and door control according to the user's actual usage habits, making the human-machine interaction process of multi-drum washing machines more continuous, intuitive and intelligent.

[0039] As a preferred example of this application, door status detection components are respectively installed at the door positions of the first drum, second drum, and other drums of a multi-drum washing machine. These door status detection components detect the status information of the corresponding doors in real time. The door status detection components can acquire information about the door's state changes, such as whether it is open, closed, or transitioning from open to closed or vice versa, and send this information to the controller. This allows the controller to accurately identify the target drum from which the operation is currently occurring based on the door status information corresponding to different drums. The door detection device can employ a Hall sensor, microswitch, or other detection structure capable of detecting door state changes. The door drive component can employ a motor drive component, electromagnetic release component, or other execution structure capable of automatically opening the door, to meet the adaptation requirements of different multi-drum washing machine product structures. In actual control, when a user directly opens a drum door, the corresponding door status detection component detects the door opening change and generates a corresponding door opening signal, which is sent to the controller. The controller then determines the target drum based on the door status information. The pre-defined correspondence between the door status detection component and the drum determines the current operation target and controls the display device to switch to the control interface of the corresponding drum. For example, when the door status detection component corresponding to the first drum detects an open signal, the controller determines the first drum as the current target drum and controls the display device to enter the first drum control interface. When the door status detection component corresponding to the second drum detects an open signal, the controller determines the second drum as the current target drum and controls the display device to enter the second drum control interface. This allows the user to perform subsequent program selection, parameter adjustment, or operation control without having to search for the corresponding drum page again through the display device after completing the door opening operation. At the same time, the controller can detect and record the closing status of each drum door to keep track of the status of each drum door in real time. Through the above limitations, the multi-drum washing machine can automatically identify the target drum by utilizing the user's natural behavior of directly operating the drum door and establish a correspondence between the physical door status and the display control interface. This reduces the user's repeated confirmation steps between the physical drum and the display interface, improving the continuity and convenience of the user experience.

[0040] As a preferred example of this application, the user inputs drum selection operation information through a display device. The drum selection operation information is used to characterize the target drum that the user wishes to use. After receiving the drum selection operation information, the controller parses the operation information and determines the corresponding target drum. At the same time, it calls the control program of the corresponding door according to the pre-established correspondence between the drum and the door, so that the drum selection operation in the display device can be directly converted into the action control of the corresponding door. This eliminates the need for the user to move to the corresponding drum position again to perform a manual door opening operation after completing the screen selection, thus improving the continuity of the multi-drum washing machine operation. In specific implementation, for multi-drum washing machines with a first drum and a second drum structure, the controller establishes a mapping relationship between the displayed selection information and the corresponding door drive component. When the controller receives drum selection operation information for the first drum from the display device, it determines the first drum as the target drum and sends a control command to the corresponding door drive component, causing the first drum door to automatically open. When the controller receives drum selection operation information for the second drum from the display device, it determines the second drum as the target drum and controls the corresponding door of the second drum to automatically open. By establishing independent correspondences for different drums, the target drum selected by the user is kept consistent with the door that actually performs the action, reducing the risk of control confusion between different doors in a multi-drum structure. Before controlling the target drum door to open, the controller further obtains the current state information of the target drum and determines whether the automatic door opening requirement is met according to preset opening conditions. The opening conditions may include the target drum door being in a closed state, the target drum not being in a prohibited door opening state, and the door drive component being in an executable state. The system comprehensively judges the status, operating status of the washing machine, and the status of the actuator to avoid automatic door opening when the door is already open, the drum is running at high speed, the drying temperature is high, or the drive mechanism is malfunctioning. When the detection result meets the preset opening conditions, the controller outputs an opening control command to the corresponding door drive component, causing the target drum door to open automatically. When the detection result does not meet the preset opening conditions, the controller stops executing the opening control and displays the reason why it cannot be opened, allowing the user to understand the equipment status in a timely manner. Through the above control process, the drum selection, opening condition judgment, and door action execution on the display device side form a complete control link, enabling the multi-drum washing machine to not only respond to user operation needs but also ensure safety and reliability during the automatic door opening process. Compared with the traditional operation method that requires the user to first select the drum control interface and then manually open the corresponding door, this implementation establishes a relationship between the display operation and the physical door, allowing the user to complete the target drum selection and door opening with a single selection operation, improving the human-machine interaction efficiency of the multi-drum washing machine. At the same time, the door action is controlled through the opening condition judgment mechanism.

[0041] As a preferred example of this application, after the user selects a target cylinder via the display device, the controller does not directly drive the corresponding door to move. Instead, it first acquires information such as the current operating status of the target cylinder, the door lock status, and the equipment fault status. Based on preset door opening conditions, it comprehensively judges whether the target cylinder meets the conditions for automatic door opening. These conditions include at least the target cylinder being in a non-operating state, the corresponding door lock being in an openable state, and no fault being detected in the current equipment. Through these conditions, the cylinder selection command generated by the display device is converted into actual door movement only when safety requirements are met. In the specific control process, the controller first selects the target cylinder... The controller determines whether the drum is in the washing, rinsing, spin-drying, or drying stage based on the corresponding operating status information. When the target drum is detected to be still in operation, the controller stops the automatic door opening process to avoid safety risks caused by the door opening due to the movement of rotating parts inside the drum, residual water inside, or high temperature environment. After confirming that the target drum is stopped, the controller further obtains the corresponding door lock status information and determines whether the door lock is in a state that allows unlocking through the door lock detection component. When the door lock is detected to be still locked, the controller does not execute the door driving action to avoid the door being forcibly opened while locked, which could damage the door lock mechanism or cause abnormal stress on the door structure. Simultaneously, the controller further detects the current operating status and fault information of the equipment to determine if there are any abnormalities affecting the door opening operation. When an abnormality is detected in the drive mechanism, control communication, sensor, or other fault conditions, the controller stops the automatic door opening control and outputs corresponding prompt information through the display device, allowing the user to understand the reason why the door opening operation cannot be performed in a timely manner. When the target cylinder's operating status, door lock status, and equipment status all meet the preset opening conditions, the controller sends a control command to the corresponding door drive component. First, it controls the door lock mechanism to release the door from its locked state. After confirming that the door lock has been released, it then controls the door drive component to drive the corresponding door of the target cylinder to open. The door is positioned at a preset angle to maintain an open state suitable for continued user operation. This preset angle can be set according to the door structure, installation location, and user operation needs. It satisfies the user's needs for putting in or taking out clothes while avoiding increased space occupation due to full door opening or safety hazards caused by sudden opening. Through the above control method, the drum selection operation, target drum status judgment, and automatic door execution in the display device form a continuous and complete control process. This allows the multi-drum washing machine to automatically match the target drum according to the user's operation intention, while also imposing safety constraints on the door opening action based on the actual state of the equipment, achieving a balance between convenient operation and safe control.

[0042] As a preferred example of this application, during the operation of a multi-drum washing machine, the controller acquires the door status information output by the door status detection components corresponding to the first and second drums in real time, and determines the user's current actual operating object by combining this information with the drum control interface corresponding to the current display device. When the display device is currently displaying the control interface corresponding to the first drum, if it detects that the door corresponding to the second drum has changed from a closed state to an open state, the controller determines, based on the status information fed back by the second drum door status detection component, that the user's current operating object has switched from the first drum to the second drum, updates the current target drum information, and simultaneously controls the display device to switch from the first drum control interface to the second drum control interface, so that the displayed content matches the drum actually opened by the user. To maintain consistency, when the display device is currently showing the control interface corresponding to the second drum, if the opening of the door corresponding to the first drum is detected, the controller performs the same state matching process, updates the current target drum to the first drum, and controls the display device to switch to the control interface of the first drum. Through this control method, the door opening action serves not only as a basis for door state detection but also as a basis for recognizing the user's actual operation intention. This allows the controller to dynamically adjust the displayed object based on the user's actual operation behavior, avoiding the problem in traditional multi-drum washing machines where the display interface is fixed to the initially selected drum, and the user still needs to manually return to the interface to switch after actually operating another drum door. In specific implementation, the controller internally stores the current display interface. The controller receives the corresponding cylinder identification information and continuously receives status change signals from different cylinder door status detection components. When an open cylinder door is detected, the controller compares the cylinder identification corresponding to that door with the currently displayed cylinder identification. If they match, the current display status remains unchanged. If they do not match, the current display status is determined to be mismatched with the user's actual operation object, and an interface update command is generated to load the control page corresponding to the currently operated cylinder on the display device. Simultaneously, to avoid erroneous switching due to factors such as door vibration and detection signal fluctuations, the controller performs validity checks on the door status change signals. For example, it continuously detects and confirms that the door is continuously open before performing the interface switch, thereby improving the accuracy of the status update. To ensure reliable identification, the control logic is based on the existing door status detection components and display control module of the multi-drum washing machine. No additional hardware structure is required; the matching and judgment process between the door status and the display status is simply added to the control program. This allows the multi-drum washing machine to adapt to various operating methods used by users in actual use. For example, if a user checks the operating information of the first drum and then temporarily opens the second drum to load or unload clothes, or if different users operate different drums consecutively, the system can automatically adjust the display interface based on the latest valid door action. This ensures that the display device, the controlled object, and the drum actually operated by the user remain consistent, improving the continuity, accuracy, and intelligence level of the two-way linkage and interactive control process of the multi-drum washing machine.

[0043] As a preferred example of this application, while receiving the cylinder selection operation information input from the display device, the controller continuously acquires the door status information fed back by the door status detection components corresponding to the first and second cylinders, and records the display operation events and door action events as user operation behaviors. Based on the occurrence time of each operation event, the controller determines the target cylinder that the user is currently focusing on. When the user simultaneously opens multiple cylinders corresponding to doors, or continuously performs opening, selection, or other operations on different cylinders within a short period, the controller does not use a fixed cylinder priority for judgment, but dynamically matches according to the occurrence order of each operation event. In specific implementation, the controller records each valid operation event... The controller generates a corresponding time stamp and records the cylinder number and operation type corresponding to the operation event. When multiple cylinder doors are detected to be simultaneously changing their opening state, the controller obtains the time information corresponding to the state change of each door and determines the cylinder whose state changed last by comparing the times. This cylinder is then designated as the current target cylinder. Simultaneously, the controller switches the display device to the corresponding control interface, ensuring that the displayed content is consistent with the cylinder whose operation was last performed by the user. For example, when the user simultaneously opens the first and second cylinder doors, the controller determines the cylinder whose state changed after the time of the two doors' state changes as the current display object and outputs corresponding status prompts through the display device, allowing the user to understand the current status. To address the issue of multiple open door states in a device, and to prevent display errors caused by multiple simultaneous operations, the controller further establishes an operation sequence recording mechanism. This mechanism incorporates both user-selected cylinders via the display device and user-triggered door opening operations into a unified decision process. When a user selects the first cylinder via the display device and then opens the second, or opens one cylinder and then selects another, the controller re-determines the target cylinder based on the latest valid operation and synchronously updates the current display screen. This ensures the system always uses the cylinder corresponding to the user's last operation as the current control object. The aforementioned limitations enable multi-drum washing machines to avoid inconsistencies between the displayed interface and the actual usage state caused by historical operation status residues in complex application scenarios such as continuous use by multiple users, alternating operation of different drums, and simultaneous opening of multiple doors. This ensures a dynamic correspondence between the displayed interface, the controlled object, and the user's current operation. Furthermore, this control method is based on existing door status detection components, display devices, and controllers, and can be completed simply by adding operation event recording, time sequence judgment, and interface matching control logic. No additional detection hardware structure is required, making it applicable to multi-drum washing machine products with different structural forms and improving the stability, accuracy, and adaptability of the two-way linkage interactive control process.

[0044] As a preferred example of this application, after the door corresponding to the target tube is opened, the controller starts a timing monitoring program and acquires user operation information and target tube status information within a preset time. When a door closing signal, clothing insertion status information, or new tube selection operation information is detected, the controller maintains the current door status or responds to the user operation again. When no clothing insertion status is detected and no new display operation information is acquired within the preset time, the controller sends a closing control command to the door drive component corresponding to the target tube, causing the door to perform an automatic closing action and controlling the display device to return to the preset display interface. Specifically, when the controller determines the target cylinder based on the cylinder selection operation information input by the user on the display device or based on the door status information, and the corresponding door of the target cylinder is in the open state, the controller continues to monitor the current target cylinder status and user operation behavior, instead of directly ending the control process after the door opening action is completed. Specifically, the controller activates a preset time monitoring mechanism and continuously acquires user operation information and cylinder status information while the door remains open. By comprehensively judging information such as whether the user continues to operate the display device, whether there is a change in clothing insertion inside the target cylinder, and whether the door remains open, the controller determines whether the user still has a need to continue using the device. When it detects that the user is performing cylinder selection, program adjustment, or operation control operations through the display device, or when it detects a change in clothing insertion status inside the target cylinder, the controller determines that the user is still in the clothing handling or... During program setup, the current door remains open and continues to respond to subsequent operations to avoid prematurely closing the door due to reaching the preset time, thus affecting normal user operation. When the user completes the operation and actively closes the door, the controller ends the current monitoring process based on the closing signal fed back by the door status detection component, restoring the device to normal control state. If the controller fails to detect valid user operation information within the preset time threshold, and also fails to detect any changes in clothing input inside the target cylinder, and the door remains open, it is determined that the current door open state may be due to misoperation, temporary user departure, or operation interruption. At this time, the controller generates an automatic door closing control command and controls the door drive component corresponding to the target cylinder to perform a closing action, restoring the door from the open state to the closed state. Simultaneously, the display device is controlled to return to the standby interface or the initial control interface, keeping the display state synchronized with the door state.In practical implementation, the preset time threshold can be flexibly set according to the structure of the multi-drum washing machine, whether it has a drying function, and user habits. For ordinary washing multi-drum washing machines, a shorter time threshold can reduce dust entry and structural aging caused by prolonged door opening. For multi-drum washing machines with drying functions, an appropriate waiting time can be set according to the internal temperature maintenance requirements to reduce heat loss and energy consumption. At the same time, the timeout shutdown control logic can be enabled for automatic door opening triggered by the display device, and can also be restricted to situations where the user directly opens the door manually. This balances the convenience of automated control with the flexibility of traditional usage. Through the above limitations, the multi-drum washing machine, based on display selection, target drum identification, and automatic door opening linkage control, further establishes a complete control closed loop of door opening status monitoring, user intent recognition, and automatic recovery closure. This allows the equipment to dynamically maintain or terminate the door opening state according to the user's actual operating needs, improving the safety, energy efficiency, and intelligence level of the two-way linkage interactive control process.

[0045] In this embodiment, to further improve the matching degree between the automatic door opening timeout closing control of the multi-drum washing machine and the actual user needs, and to avoid the door closing prematurely during normal operation due to a fixed timeout, or safety hazards and energy waste caused by the door being open for a long time, the preset time threshold in the automatic door closing control process is set differently. Specifically, the controller dynamically adjusts the waiting time after the door is opened based on the current operating status of the multi-drum washing machine, the working status of the target drum, and the actual user scenario, so that different timeout closing strategies correspond to different usage scenarios. In specific implementation, when the user opens the drum door after completing the washing program to take out clothes, arrange clothes, or allow natural ventilation inside the drum, the controller recognizes... When the washing machine is not currently in a clothes removal and ventilation scenario, the automatic door closing wait time is set to a first preset time threshold, such as 3 minutes. This allows users to keep the door open while removing clothes, organizing them, taking out hangers, or cleaning residue from the drum. This also prevents dust from entering the drum due to prolonged door opening, avoids long-term stress on the door structure, and prevents children or pets from accidentally touching the drum. When the multi-drum washing machine is in a scenario where the washing program is paused, clothes are added mid-cycle, or the clothing status is temporarily adjusted, the controller identifies the current scenario as adding clothes mid-cycle and sets the automatic door closing wait time to a second preset time threshold, such as 1 minute. This is because the washing program has not yet ended, and there may be water or subsequent operational needs inside the drum. By shortening the door opening time, users can quickly load clothes or make simple adjustments, while reducing the risk of leaks, accidental start-ups, or accidental contact with the drum's internal structure due to prolonged door opening. When the multi-drum washing machine is empty and not running a program, and the user opens the door primarily for odor dissipation, ventilation, or checking the drum's internal environment, the controller recognizes this as an empty-machine ventilation scenario and sets the automatic door-closing waiting time to a third preset threshold, such as 5 minutes. Since the user doesn't need to immediately start the washing program in this scenario, the door is allowed to remain open for a longer period to ensure sufficient odor dissipation and ventilation. After 5 minutes, the door automatically closes to prevent the machine from remaining open for extended periods. In another embodiment, the controller can also perform tiered control of the automatic door closing time based on the current operating status of the multi-drum washing machine. Specifically, when the washing machine is running or paused during a washing program, a shorter preset time threshold is set, such as 1 minute, to prioritize operational safety. When the washing machine is in standby mode, a medium preset time threshold is set, such as 3 minutes, to meet user ventilation needs while also considering safety management. When the washing machine is turned off, a longer preset time threshold is set, such as 5 minutes, to meet user needs for drum ventilation and odor dissipation when the equipment is not running. Furthermore, the preset time threshold for the off state is set to be greater than the preset time threshold for the standby state.The preset time threshold for the standby state is greater than the preset time threshold for the washing program running state. Furthermore, to accommodate different user home environments and usage habits, the controller can also provide an overtime adjustment interface via a display device, allowing users to manually switch between different time settings according to their actual needs. For example, users can set a 1-minute short time setting, a 3-minute medium time setting, and a 5-minute long time setting. The 1-minute setting is suitable for homes with children or pets to reduce the safety risks associated with prolonged door opening. The 3-minute setting is the default setting, balancing the needs of clothes preparation, drum ventilation, and automatic door closing. The 5-minute setting is suitable for single-person households or those requiring... In scenarios where the drum door needs to be kept open for extended periods for ventilation and odor removal, the differentiated time control method based on equipment operating status and user scenarios allows the automatic door closing function to move beyond a single fixed time judgment. Instead, it dynamically adjusts the door opening time according to actual user needs. This ensures user convenience while effectively reducing safety risks, energy loss, and equipment aging caused by prolonged door opening. This creates a complete closed-loop control system for multi-drum washing machines, from display operation triggering, automatic door opening, user behavior recognition, to automatic closing after timeout, improving the intelligence level and reliability of the two-way interactive control system.

[0046] As a preferred example of this application, during the automatic closing action of the door corresponding to the target cylinder, obstacle detection information fed back by the anti-pinch sensor component set around the door is acquired. When an obstruction is detected in the closing path of the door, the controller stops outputting the closing drive signal and controls the door to retract a preset distance in the opening direction. At the same time, the controller controls the display device to generate obstacle warning information to avoid the door from pinching the user, clothing, or foreign objects during the closing process. Specifically, when the controller determines, based on a preset time threshold, that the user has not continued to perform clothing insertion, program settings, or other effective operations within a preset time after the automatic opening, and outputs a closing control command to the door drive component corresponding to the target cylinder, the controller synchronously activates the anti-pinch sensor component set around the cylinder door to detect the closing path of the door in real time. The anti-pinch sensor component can be at least one of an infrared detection component, a capacitive sensing component, or a pressure detection component, and is set in the edge area of ​​the door or the corresponding position of the door frame to collect obstacle status information in the closing area during the door movement. During the process, as the door moves from the open position to the closed position, the controller continuously acquires the detection signals from the anti-pinch sensor component and determines whether there are user hands, clothing, debris, or other foreign objects in the closed area between the door and the door frame. When the closed area of ​​the door is detected to be unobstructed, the controller continues to maintain the closing drive signal, causing the door to close and lock according to the preset action. When abnormal obstruction or blockage is detected during the closing process, the controller immediately stops the current closing action and cuts off the closing drive force of the door drive component to prevent the door from continuing to move and causing the foreign object to be continuously pressed. At the same time, the controller controls the door to perform reverse micro-operation. The opening action causes the door to retract a preset distance in the opening direction, releasing the clamping space between the door and the door frame and reducing the pressure on users, clothing, or foreign objects. After completing the stopping and retraction actions, the controller further controls the display device to output corresponding prompts, such as displaying an obstacle detection prompt to guide the user to clear obstacles around the door before resuming the closing operation. Through the above control method, the automatic door closing process is transformed from a simple time-based control to an intelligent safety control process that combines real-time environmental detection. While ensuring automatic door closing, preventing forgetting, and reducing energy consumption, it effectively avoids automatic closing... During the closing process, issues such as user hand injuries, clothing damage, and obstruction of the door drive components may occur. Simultaneously, this anti-pinch control logic works in conjunction with the aforementioned control processes, including display operation-triggered door opening, automatic door closing after timeout, target drum switching, and multi-drum timing calibration. It can be implemented simply by adding an anti-pinch signal acquisition and judgment program to the existing control system, without altering the main structure of the washing machine. This makes it applicable to multi-drum washing machine products with different structural forms, further improving the safety protection closed loop in the two-way linkage and interactive control process of multi-drum washing machines. This enhances the safety and reliability of the equipment during use while providing intelligent automatic control capabilities.

[0047] As a preferred example of this application, after the door corresponding to the target drum is opened, the controller controls the display device to switch to the program selection interface corresponding to the target drum according to the identification information corresponding to the target drum, and switches to the corresponding parameter configuration interface after the user selects a program. The program selection interface is used to display multiple program options corresponding to the target drum, and the parameter configuration interface is used for the user to adjust the operating parameters such as washing time, washing temperature, rinsing times and spin speed of the corresponding program. In addition, the controller also obtains the weight and humidity information of the clothes according to the drum status detection component set in the drum, and determines the recommended program from the program set corresponding to the target drum according to the weight and humidity information of the clothes, and displays the recommended program in the program selection interface first, so that the user can confirm and execute the program control. Specifically, each drum door of the multi-drum washing machine is equipped with a door status detection component for detecting the door's open state. The door status detection component is preferably located at a microswitch at the drum door hinge. When the user physically opens any target drum door, the microswitch at the hinge is mechanically triggered and switches from an off state to a conducting state, generating an opening detection signal for the corresponding drum. This signal is sent to the controller. The controller identifies the target drum currently being operated on based on the received opening signal and invokes a preset drum-to-display interface mapping relationship. It then automatically switches the display device to the control interface corresponding to the target drum, allowing the user to directly access the corresponding drum's program operation page without having to select the drum again through the display device. In this control interface, the display device prioritizes displaying the set of programs supported by the current drum, including standard wash, quick wash, heavy-duty wash, gentle wash, rinse, spin-only, and drying programs. The user can directly select the target program based on the type of clothing. When the user completes the program... After the selection of the program, the controller further controls the display device to enter the corresponding parameter configuration interface, which centrally displays the adjustable parameters for the current program, including washing time, washing temperature, number of rinses, and spin speed. This allows users to adjust parameters according to the fabric type, degree of soiling, and actual usage needs, avoiding repeated switching between multiple pages. This interface-linked control logic applies not only to scenarios where the user manually opens the drum door but also to scenarios where the user selects the target drum via the display device and triggers automatic door opening. After the user completes the target drum selection via the display device, the controller controls the corresponding door drive component to perform an automatic opening action. During the door opening process, it simultaneously sends an interface switching command to the display device, causing the display device to enter the target drum program selection interface and parameter configuration interface according to the same process as manual door opening. This ensures that the physical door opening operation path and the display operation path ultimately correspond to a unified interaction logic, guaranteeing a consistent user experience regardless of the usage method. In a further implementation, to reduce the complexity of program selection for the user...To improve the intelligence level of program control, this application also sets up drum state detection components in each drum to detect the state information of clothes placed in the target drum. These drum state detection components include at least a weight detection component and a humidity detection component. The weight detection component obtains the weight of the clothes currently placed in and determines the load status, while the humidity detection component obtains the moisture content of the clothes. The controller analyzes the detected weight and humidity information against preset program matching rules, selects recommended programs from the program set corresponding to the target drum that match the current state of the clothes, and displays them on the program selection interface through top display, highlighting, or default selection. This allows users to quickly confirm the recommended program and start it with the corresponding parameters. Through this control method, the multi-drum washing machine forms a continuous control process consisting of door state detection triggering drum recognition, synchronous switching of the display interface, program selection, parameter configuration, and intelligent program recommendation. This achieves real-time correlation between user operation and device display status, improving the interactivity of the multi-drum washing machine while reducing user operation complexity and enhancing the intelligence level of the device.

[0048] As a preferred example of this application, capacitive proximity sensors are installed at the handle positions of each cylinder door to detect the user's approach to the target cylinder before the user actually opens the door. When the user's hand gradually approaches a cylinder door handle, the capacitive proximity sensor generates a proximity detection signal by detecting the capacitance change caused by the human body's approach and sends the proximity detection signal to the controller. The controller determines the target cylinder that the user may be operating based on the position of the door handle that generated the proximity detection signal, and enters an interface preloading state based on a preset cylinder-interface resource mapping relationship. This preloading displays the corresponding target cylinder's program selection interface, parameter configuration interface, program icon resources, and... Default control parameters and other data are pre-read and cached in the corresponding storage area of ​​the display device. During the preloading process, the display device maintains its current display state and does not immediately switch interfaces to avoid accidental switching when the user only approaches the door but does not actually operate it. When the user further performs the door opening action, the door status detection component located at the door hinge detects the door opening status and sends a formal door opening signal to the controller. The controller confirms the user's operation intention based on the door opening signal and determines whether the interface resources corresponding to the target cylinder have been pre-loaded. When the interface resources have been cached, the controller directly calls the interface data in the cache area and controls the display device to quickly switch to the target cylinder. The control interface allows users to directly access the washing program selection page for the corresponding drum after opening the door, without waiting for interface resources to be re-read and parsed. If preloading is incomplete, the controller switches the interface according to the standard interface loading process to ensure system reliability. This control method transforms the display interaction of multi-drum washing machines from a traditional door-open-response mode to a pre-preparation mode based on user behavior prediction. This enables a continuous control process: intent recognition when the user approaches the door, data preparation before door opening, and rapid display after door opening. Furthermore, this preloading mechanism integrates with the aforementioned door opening detection, automatic door opening upon drum selection, and automatic timeout. The control logic, including closing and intelligent program recommendation, works together to allow users to quickly access the corresponding control interface whether they open the drum door manually or select the target drum through the display device. This ensures consistency in interface display and continuity of operation during the two-way linkage control process. In addition, this solution uses capacitive proximity sensing elements to achieve non-contact user behavior detection without affecting the original door structure and drive mechanism. Interaction optimization can be achieved simply by adding proximity signal acquisition and interface buffer control programs. It features strong structural adaptability, fast response speed, and wide application range, and can effectively improve the user experience of multi-drum washing machines in scenarios with large-size color screens, multi-program control, and intelligent interaction.

[0049] In this embodiment, to further expand the two-way interactive control method of the multi-drum washing machine and enable users to complete target drum selection, door opening, and display interface switching operations through a more natural human-computer interaction, this application further introduces a voice control linkage mechanism. Specifically, the multi-drum washing machine is equipped with a voice acquisition module and a voice recognition processing module. The voice acquisition module is used to acquire the voice control information input by the user and transmit the acquired voice signal to the controller. The controller parses the user's voice content through the voice recognition processing module, extracting the target drum information and operation intent information contained therein. When the user issues voice commands such as "I want to wash the upper drum," "Open the upper drum door," or "Use the lower drum for washing," the controller... The controller determines the target cylinder that the user needs to operate based on preset semantic recognition rules and calls the corresponding cylinder's control logic. First, it detects the target cylinder's state to determine if it meets the opening conditions, such as the current door state, cylinder operating state, and safety lock state. When the preset conditions are met, the controller sends an automatic door opening control command to the door drive component corresponding to the target cylinder, causing the target cylinder door to open according to the preset action. Simultaneously, the controller sends an interface switching command to the display device based on the recognized target cylinder information, switching the display device from the current display interface to the control interface corresponding to the target cylinder, and further entering the program selection interface or parameter configuration interface, allowing the user to select the cylinder via voice. Afterwards, the washing program can be set directly without manually selecting the drum via the touchscreen. In practice, the voice control logic works in conjunction with the aforementioned display selection trigger automatic door opening, door opening detection trigger interface switching, and proximity sensing preloading mechanism. When the controller receives a valid voice command and identifies the target drum, it can pre-load the corresponding drum interface resources. The display interface is prepared synchronously during the door opening process, creating a continuous linkage between voice command execution, door action response, and screen interaction. For example, when a user says "I want to wash the upper drum," the controller recognizes the target drum in the command as the upper drum, controls the upper drum door to open automatically, and simultaneously switches the color screen to the upper drum control page, displaying the upper drum support... With the selected program, currently adjustable parameters, and recommended program information, users can directly select the corresponding program to complete subsequent washing settings. This control method expands the multi-drum washing machine's interaction mode from the traditional button or touch operation to an intelligent interaction mode that integrates voice, door, and display interfaces. Users can control the device using natural language that aligns with their daily usage habits. Furthermore, voice recognition identifies the target drum and triggers door opening and interface switching, avoiding repetitive operations across multiple control points and improving the ease of operation and intelligence of the multi-drum washing machine. Moreover, this voice control mechanism is based on existing controllers, voice acquisition modules, and door drive components, requiring no changes to the main structure of the washing machine.It can form a complete interactive loop with functions such as drum recognition, automatic door opening, timeout closing, anti-pinch protection, and program recommendation in two-way linkage control, enabling multi-drum washing machines to have full-process intelligent control capabilities from user voice intent recognition, target drum matching, door execution to washing program configuration, further enhancing the human-machine interaction experience of the equipment.

[0050] This application also discloses a two-way linkage multi-drum washing machine, including: The body contains multiple independent cylindrical sections. The door assembly includes multiple door bodies that are arranged in a one-to-one correspondence with the multiple cylindrical bodies; The display device is used to receive the cylinder selection information input by the user and display the control interface corresponding to the target cylinder. Door status detection components are respectively installed at each of the door bodies to detect the opening and closing status changes of the corresponding door bodies. A door drive assembly is connected to each of the doors and is used to drive the corresponding door to perform an opening or closing action according to a control command. The controller is connected to the display device, the door status detection component, and the door drive component, respectively. It is used to determine the target drum based on the door status information detected by the door status detection component, and control the display device to switch to the control interface corresponding to the target drum. It also determines the target drum based on the drum selection information received by the display device, and controls the door drive component corresponding to the target drum to perform the door opening action when the preset door opening conditions are met. This enables the multi-drum washing machine to achieve bidirectional linkage control between drum recognition, interface switching, and door action based on changes in door status and user interface operation.

[0051] This application discloses a bidirectional linkage multi-drum washing machine. By establishing a bidirectional correlation control relationship between door status detection, user interaction input, door drive execution, and display interface control, it enables users to choose physical operation or display operation as the interaction entry point according to their actual usage habits. The washing machine automatically completes target drum identification, door status adjustment, and control interface matching, thereby solving the problem in existing multi-drum washing machines where door operation and display control are independent, requiring users to repeatedly confirm, manually match, and perform multiple operations between the physical drum and the display interface. Specifically, the multi-drum washing machine includes a machine body, multiple independent drums disposed inside the machine body, and door components respectively disposed corresponding to each drum. The washing machine comprises a display device, a door status detection component, a door drive component, and a controller. Multiple drums are used to categorize and wash different types of clothing. Each drum is equipped with an independent door component, allowing users to perform operations such as loading, unloading, and maintenance on the target drum. The door status detection component is correspondingly configured to each door, detecting its open, closed, or status change information and sending the detected door status signal to the controller. The door drive component is connected to the corresponding door and automatically opens or closes the door according to the drive commands output by the controller. The display device serves as the human-machine interface between the user and the washing machine, receiving user-input drum selection information and displaying the target drum. The controller has a control interface corresponding to the target cylinder and provides feedback on the user's operation results. It is communicatively connected to the door status detection component, the door drive component, and the display device. It comprehensively processes door status information, user input information, and execution feedback information, and synchronizes the door status with the display interface according to preset control logic. In specific implementation, when a user directly opens the door corresponding to a specific cylinder, the door status detection component located at that door detects the door changing from a closed state to an open state and sends the corresponding cylinder's status signal to the controller. The controller identifies the target cylinder currently being operated by the user based on preset identification information for different cylinders and sends an interface switching command to the display device, causing the display device to automatically switch modes. The system includes a control interface corresponding to the target drum. This interface can further display the washing program, operating status, and parameter setting entry for that drum, allowing users to directly access the corresponding operation page without having to select the drum again via the display device. This achieves first-direction linkage where the physical door movement triggers changes in the display interface. In another embodiment, when the user selects the target drum via the display device, the display device sends the user's input drum selection information to the controller. The controller determines the target drum based on the selection result and obtains the current operating status, door lock status, and security detection information of the target drum. When preset opening conditions are met, the controller sends an automatic door opening control command to the corresponding door drive component, causing the target drum door to open automatically.Simultaneously, the controller synchronously switches the display device to the control interface corresponding to the target drum, realizing a second-direction linkage where the display operation drives the physical door movement. During this bidirectional linkage, the controller coordinates the door status detection signal, display interaction signal, and door drive signal, ensuring that both physical door opening and display selection operations correspond to the same target drum. Interface switching and door response are completed through unified control logic. Furthermore, the controller can also expand its functionality based on this bidirectional linkage architecture to include automatic door closing control, anti-pinch detection, interface preloading, voice control, and intelligent washing program recommendation. This allows the washing machine to proactively match status and prepare functions based on user actions. During operation, the controller continuously acquires door status information from each drum door status detection component and determines the user's current operation based on the received status changes. When a door is detected to be open, the controller calls the preset drum identifier and display interface mapping relationship, converts the corresponding drum information into an interface switching command, and sends it to the display device, ensuring the displayed content matches the user's actual operation. When the user inputs a drum selection command through the display device, the controller determines the target drum based on the user's selection and controls the corresponding drum after completing a safety status check. The door drive component activates, simultaneously updating the target drum information on the display device to synchronize the screen display status with the actual door status. Through this control process, a complete closed loop is formed, encompassing user input, target drum recognition, control command execution, and status feedback. This avoids the manual matching required between the display interface and the physical door in traditional multi-drum washing machines. This structure and control method improve the human-machine interaction convenience and operational consistency of multi-drum washing machines, allowing users to complete the washing preparation process according to their own habits without learning complex operating paths. Furthermore, using a single controller to uniformly manage detection signals, interaction commands, and execution actions avoids problems such as drum recognition errors, display interface mismatches, and abnormal door responses caused by information asynchrony between multiple control modules, improving system stability. In addition, this bidirectional linkage control architecture is mainly achieved through the cooperation between the detection component, drive component, and control program, without significantly altering the main structure of the washing machine. It can adapt to multi-drum washing machine products with different structural forms and provides a unified hardware and control foundation for subsequent intelligent interactive function expansion. This transforms the multi-drum washing machine from a traditional device passively executing control commands into an intelligent device capable of sensing user operations and proactively providing interactive feedback.

[0052] As a preferred example of this application, the drum body includes a first drum body and a second drum body arranged vertically upwards and downwards. The door body includes a first drum door and a second drum door respectively disposed on the first drum body and the second drum body. The first drum body and the second drum body respectively form independent washing spaces to meet the needs of different clothing classification and processing. The first drum door and the second drum door respectively correspond to independent door control paths, enabling the controller to accurately identify the target drum body according to the user's operation. Furthermore, each drum door is provided with a door status detection component for detecting the opening state, closing state, and opening / closing change process of the corresponding drum door. The door status detection component can be at least one of a Hall sensor, a micro switch, a reed switch, and a capacitive proximity sensor, preferably... Located between the drum door and the machine frame, at the drum door hinge, or in the door handle area, this device acquires door status information by detecting changes in magnetic fields, mechanical trigger states, or electrical signal changes caused by human proximity. This detection signal is then sent to the controller, enabling the controller to determine the first or second drum currently being operated by the user based on the detection signal corresponding to different drum doors. The controller then switches the display device to the corresponding drum's operating interface. The display device, preferably a color touchscreen display on the front panel of the machine, is positioned between the first and second drums. It receives user input regarding drum selection, washing program selection, and parameter adjustments, and displays the control interface corresponding to the target drum, allowing the user to select the appropriate drum via the display. The interaction method involves selecting a cylinder and triggering the action of the physical door. Furthermore, each cylinder is equipped with a corresponding door drive component, used to drive the corresponding cylinder door to automatically open or close according to control commands output by the controller. The door drive component includes at least one of an electromagnetic door lock, an electric push rod, a micro servo motor drive mechanism, or a motor-driven door hook mechanism. The controller, based on the target cylinder selection information received from the display device, judges the current operating state, door lock state, and safety conditions of the target cylinder. When preset opening conditions are met, the controller controls the door drive component to automatically open the corresponding cylinder door, thereby achieving bidirectional linkage control between the display interface state and the physical door state. Furthermore, to improve safety during the automatic closing process... Each drum door edge is also equipped with an anti-pinch detection component. This component can employ an anti-pinch infrared sensor, a capacitive touch sensor strip, or other detection elements capable of detecting obstacles. The detection signal is connected to the controller to determine in real time whether a person, clothing, or other foreign object is present in the door's closing path. When an abnormal obstruction is detected, the controller, based on the anti-pinch control signal, controls the door drive assembly to stop closing or reverse the opening action to prevent the door from pinching the user or damaging clothing. Furthermore, to improve the multi-drum washing machine's ability to recognize actual usage conditions, clothing detection components can also be configured inside the first and second drums. These components include at least one of a weight sensor and an infrared release sensor.This system detects whether clothes are inside the drum and obtains the current load information, feeding the results back to the controller. The controller then determines the drum's usage status based on the detection results and, in conjunction with program recommendations, operational control, and interactive display logic, completes the subsequent control process. Through these further limitations, the bidirectional multi-drum washing machine can achieve coordinated control based on a unified controller, including drum recognition, door detection, automatic door opening, display switching, anti-pinch protection, and clothes status perception. This ensures a consistent interactive experience for users whether they enter the washing process through the physical drum door or a touchscreen. Furthermore, the combined design of multiple types of sensing and drive components allows for flexible selection of hardware solutions based on different product positioning, improving overall machine adaptability and intelligence while ensuring control reliability. This provides the hardware foundation for safer, more convenient, and continuous human-machine interaction in multi-drum washing machines.

[0053] This application discloses a two-way linkage interactive control method for a multi-drum washing machine and a multi-drum washing machine. By establishing a two-way correlation between door status detection, display interface control, and door drive control, users can select different operation entry points according to their own usage habits. The washing machine automatically completes target drum identification, interface matching, and door response, thereby realizing the transformation from the traditional one-way interaction mode to a two-way closed-loop interaction mode. Specifically, this method includes linkage control in two directions: "physical → digital" and "digital → physical." In the "physical → digital" linkage direction, the controller acquires the status information of the corresponding door of each drum in real time. The door status information is collected by a door status detection component set at the door position. When the user directly opens a door... When the cylinder corresponds to a door, the door status detection component detects that the door has changed from a closed state to an open state and sends the corresponding cylinder opening signal to the controller. The controller identifies the target cylinder that the user is actually operating based on the received door status signal, and calls up the preset cylinder-display interface correspondence. It then controls the display device to automatically switch to the control interface corresponding to the target cylinder. For example, when the user opens the upper cylinder door, the controller identifies the opening signal corresponding to the upper cylinder and controls the display device to switch to the upper cylinder control interface. When the user opens the lower cylinder door, it controls the display device to switch to the lower cylinder control interface. This allows the user to enter the corresponding operation page without having to select the cylinder again through the display device, realizing a control method where the display interface is directly triggered by the user's physical operation.

[0054] In the "digital → physical" linkage direction, the user can input a target cylinder selection command through a display device, preferably a color touch screen located on the front panel of the machine body. The user selects the target operation object by clicking the upper cylinder icon, lower cylinder icon, or the corresponding cylinder label. The display device sends the cylinder selection information input by the user to the controller. The controller determines the target cylinder based on the user's selection result and detects and judges the current status of the target cylinder, including the cylinder's operating status, door lock status, security status, and whether the door opening conditions are met. When it is determined that the preset door opening conditions are met, the controller sends an automatic door opening control command to the corresponding door drive assembly. After receiving the control command, the device drives the corresponding door to open automatically, allowing the user to complete the door opening operation without having to move to the corresponding drum position. This realizes the control method of selecting the physical door action through the display interface. Through the above two independent yet complementary linkage control, the multi-drum washing machine can cover different operating scenarios in the actual use process. When the user is used to walking directly to the target drum and opening the door, the system can automatically match the display interface according to the door action. When the user is used to selecting functions through the color screen first, the system can automatically open the corresponding drum door according to the screen operation, so that the user does not need to find and pull the door again, thus forming a complete interactive closed-loop control process.

[0055] Furthermore, to avoid inconsistencies between the displayed state and the actual operation object, this embodiment also includes a drum state interlock logic. When the display device is currently displaying a certain drum control interface, if it detects that another drum door has been opened, the controller uses the last detected valid door operation as the current target drum and updates the display device interface synchronously. For example, when the display device is currently displaying the upper drum control interface, if the user manually opens the lower drum door, the controller, upon detecting the lower drum door opening signal, immediately updates the target drum to the lower drum and controls the display device to switch to the lower drum control interface. This avoids misoperation caused by inconsistencies between the user's actual operation object and the screen display object, improving the consistency of the state during the interaction process of a multi-drum washing machine. To improve safety and reliability after automatic door opening, this embodiment can also be configured with timeout automatic door closing control logic. When the controller automatically opens a certain cylinder door according to the operation selected by the display device, if no clothing insertion signal, cylinder state change signal, or user further operation signal is detected within a preset time, the controller controls the door drive component to perform an automatic closing action and returns the display device to the standby interface. Here, a weight sensor or infrared placement sensor can be configured inside the cylinder to detect whether clothing is inserted and send the detection result to the controller to help determine whether the user has completed the use process, avoiding the door from being in the open state for a long time, which may lead to changes in the internal environment, foreign objects entering, or energy waste.

[0056] This application presents a bidirectional linkage interactive control method for multi-drum washing machines. Its working principle is primarily based on three processes: door status perception, user operation recognition, and controller synchronization. During system operation, the controller continuously receives door status information collected by the door status detection components corresponding to each drum, and simultaneously monitors user interaction commands generated by the display device. When a user physically opens a drum door, the door status detection component first detects the change in door status and generates an opening signal for the corresponding drum, sending it to the controller. The controller determines the user's current actual operation target based on the preset identification identifiers for different drums, and calls the corresponding display interface configuration data based on the target drum information, controlling the display device to complete the interface switching. This ensures that the door action and screen display remain synchronized, achieving a "physical → digital" linkage process. This process uses the user's completed physical action as the target recognition basis, allowing the washing machine to complete interface matching without waiting for the user to make another screen selection. When the user selects a drum via the display device, the controller receives the selection signal sent by the display device and, based on the user's selection... Once the target drum is identified, and it is further determined whether the target drum meets the automatic door opening conditions, if the conditions are met, the controller sends a drive signal to the corresponding door drive component, causing the door drive component to perform the opening action. At the same time, the controller synchronously updates the target drum status in the display device, so that the display interface is consistent with the actual door status, realizing the reverse control process of "digital → physical". In the control process in both directions, the controller uniformly processes the door status signal, display operation signal and actuator feedback signal, and calibrates the current target drum in real time through interlock logic. When different operation paths occur consecutively, the last valid operation of the user is used as the basis for status judgment, so that the screen display, door status and user operation intention always maintain a corresponding relationship. At the same time, combined with auxiliary control logic such as automatic door closing, anti-pinch detection and clothing insertion detection, a complete closed-loop control process is realized from user operation input, target object recognition, control action execution to status feedback display. This transforms the multi-drum washing machine from a traditional device that passively executes control commands into an intelligent interactive device that can actively understand the user's operation intention and provide corresponding services.

[0057] Through the aforementioned two-way linkage control method, this application significantly improves the human-machine interaction convenience, operational consistency, and intelligence level of multi-drum washing machines. Firstly, compared to existing multi-drum washing machines that typically only achieve a one-way association between the door status and the display interface, this application simultaneously realizes control relationships in both the "physical → digital" and "digital → physical" directions. This allows the washing machine to automatically complete the state matching on the other side, forming a complete interactive loop, regardless of whether the user enters the usage process from the physical operation end or the display interaction end. This changes the traditional smart washing machine's color screen from merely serving as an information display window, upgrading it from a "passive response" to an "active service" capable of controlling physical actions, effectively reducing the cognitive burden on users during operation. Secondly, by triggering the screen-switching function upon door opening, users can directly enter the corresponding control interface by opening the target drum door, eliminating the need to search for the drum icon again or perform repeated selection operations, reducing operation steps and improving operational continuity. Simultaneously, by triggering the door opening function through screen switching, users can directly select the target drum on the color screen and control the door to open automatically, avoiding the need for users to move to the corresponding position to manually open the door. This is especially suitable for situations where the lower drum is low and it is inconvenient for users to bend over to operate. Alternatively, in scenarios where users are holding clothes, laundry supplies, etc., this improves the convenience and accessibility of the device. Furthermore, by setting up interlocking logic, the system can adjust the target drum in real time based on the user's last valid operation, avoiding inconsistencies between the displayed interface and the actual opened door, reducing user misjudgments and misoperations, and improving the reliability of the interaction process. In addition, by setting up automatic door closing control and anti-pinch detection components, the door can be closed in time if no valid usage behavior is detected after automatic opening, avoiding energy waste or foreign object entry caused by prolonged door opening. At the same time, the anti-pinch detection component can detect the obstacle status during the door closing process and send an anti-pinch control signal to the controller, causing the controller to stop the door from closing or perform a reversing action, improving the safety of use. Overall, this application unifies the control of door detection, display interaction, automatic drive, and safety detection, enabling multi-drum washing machines to transform from one-way command execution to two-way intelligent interaction. This not only optimizes the user operation process but also enhances the interactive experience and functional expansion capabilities of intelligent washing machine products, providing a unified control foundation for subsequent integration with intelligent functions such as voice control, interface preloading, and intelligent program recommendation.

[0058] Example 1: Control flow for switching display interface based on door opening action like Figure 1As shown, this embodiment provides a two-way linkage interactive control method for a multi-drum washing machine. It mainly realizes the control process where the user triggers the display interface automatically through physical door operation, achieving "physical → digital" linkage control. After the multi-drum washing machine is powered on, the display device 8 (color screen display) defaults to displaying the interface before the last shutdown, such as the upper drum control interface or the multi-drum status homepage. The controller 10 continuously and cyclically detects the door status signals output by the door status detection components corresponding to the first drum door 5 (upper drum door) and the second drum door 6 (lower drum door). When the user needs to use the first drum 3 (upper drum) for washing clothes, the user can directly walk to the washing machine and open the first drum door 5. At this time, the microswitch set between the first drum door 5 and the door frame of the machine body 2 detects that the door has changed from a closed state to an open state and generates a high-level door opening detection signal sent to the controller 10. The controller 10 then performs the corresponding detection based on the received signal. The controller 10 determines that the current operating object is the first drum 3 and immediately sends an interface switching command to the display device 8, causing the display device 8 to switch from the current display interface to the upper drum control interface. The upper drum control interface displays the selectable washing programs corresponding to the first drum 3, including standard wash, quick wash, and drying options. After the user puts the clothes into the first drum 3, they can directly set the washing parameters and start the operation on the current interface. When the user needs to use the second drum 4 for washing, the controller 10 detects the opening status of the second drum door 6 in the same way and controls the display device 8 to switch to the lower drum control interface according to the door status detection signal corresponding to the second drum door 6. This enables the display device to automatically identify the corresponding drum and complete the interface matching when the user directly operates the physical drum door, avoiding the user having to select the target drum again through the screen, reducing operation steps, and improving the response consistency between physical operation and digital interaction.

[0059] Example 2: Conflict handling and default interface control flow based on gate state priority In this embodiment, to avoid inconsistencies between the displayed interface and the actual operating object when multiple cylinder doors change simultaneously, a door state conflict handling logic is further implemented. When the controller 10 detects that both the first cylinder door 5 and the second cylinder door 6 generate opening signals simultaneously, the controller 10 determines the current target cylinder according to a preset priority rule, preferably selecting the cylinder door that last opened as the current user operation object, and controls the display device 8 to switch to the corresponding cylinder control interface. For example, when the display device 8 is currently in the upper cylinder control interface, and the user subsequently opens the second cylinder door 6, the controller 10 determines that the user's current operation target has switched to the second cylinder door 4 based on the latest opening signal generated by the second cylinder door 6. The controller immediately switches the display device 8 to the lower drum control interface. At the same time, it can display a prompt message such as "Both drum doors are open, currently controlling the lower drum" to help the user confirm the current control status. When the user closes the corresponding drum door, if no further screen operation, program selection, or washing start operation is detected within 30 seconds, the controller 10 controls the display device 8 to automatically enter the standby black screen state, or return to the main interface displaying the operating status of the first drum 3 and the second drum 4. When the user opens any drum door again, the controller 10 responds to the door status detection signal again and controls the display device 8 to wake up and switch to the corresponding drum control interface, thereby reducing energy consumption caused by invalid displays.

[0060] Example 3: Hardware Structure Implementation of a Two-Way Linkage Multi-Tube Washing Machine See Figure 2This embodiment provides a multi-drum washing machine structure that implements the above-mentioned bidirectional linkage control method. The multi-drum washing machine 1 includes a body 2, a first drum 3, a second drum 4, a first door 5, a second door 6, a hinge 7, a display device 8, a door status detection component, a controller 10, and a door drive component 11. The first drum 3 and the second drum 4 are arranged vertically along the body 2 and form independent washing spaces. The first door 5 and the second door 6 are respectively mounted on the body 2 via hinges 7 and are used to open and close the corresponding drums. The display device 8 is located on the front panel of the body 2 and is used to display the control interface corresponding to the first drum 3 and the second drum 4 and to receive user touch operations. In this embodiment, the door status detection component is located between the door and the door frame of the body 2. Specifically, it can be a Hall sensor, a micro switch, or a reed switch structure. Preferably, the door status detection... The components include a Hall sensor 9 mounted on the door and an inner circle sensing device 12 (magnet) mounted on the door frame. When the door is closed, the Hall sensor 9 detects changes in the magnetic field and outputs a low-level signal. When the door is open, the Hall sensor 9 moves away from the magnet and outputs a high-level door opening signal. The controller 10 is installed in the control box inside the body 2. Its input is connected to the door status detection component, and its output is connected to the display device 8 and the door drive component 11, respectively. The controller 10 has a built-in control program that executes a two-way linkage control method. When the controller 10 detects that the output signal of the Hall sensor 9 corresponding to the first cylinder door 5 changes from a low level to a high level, it determines that the first cylinder door 5 is open and controls the display device 8 to switch to the upper cylinder control interface. When the cylinder selection signal input by the display device 8 is received, the controller 10 drives the corresponding door drive component 11 to perform an automatic door opening action according to the user's selection result.

[0061] Example 4: Intelligent Program Recommendation and Interface Preloading Extension Control Based on In-Cylinder State Detection In this embodiment, to further enhance the intelligent interaction capabilities of the multi-drum washing machine, an in-drum status detection component is further installed inside the first drum 3 and the second drum 4. This component identifies the state of clothes being loaded into the drum and sends a detection signal to the controller 10. The in-drum status detection component can be a weight sensor or an infrared sensor. When the user opens the corresponding drum door, the controller 10 obtains the target drum information based on the door status detection component, and simultaneously obtains the weight of the clothes or the information of clothes being loaded from the in-drum status detection component. Based on the detection results, the controller recommends the corresponding washing program to the display device 8. For example, it automatically recommends standard wash, quick wash, or drying programs based on the detected weight of the clothes, reducing the user's manual setting process and improving the accuracy of program selection. In addition, in another embodiment, the door status detection component can also be a capacitive proximity sensor. When the user's hand approaches the door handle area, the capacitive proximity sensor detects the capacitance change caused by the human body approaching and sends a pre-detection signal to the controller 10 in advance. The controller 10 preloads the program page, icon resources, and control parameters corresponding to the target drum based on the pre-detection signal. When the user further performs the door opening action, the display device 8 can quickly complete the interface switching, realizing pre-loading control and reducing the waiting time for the interface to load after opening the door.

[0062] Example 5: Second-direction linkage control process based on display selection triggering automatic door opening In this embodiment, the main function is to enable the user to control the opening of the physical door via the display device 8, i.e., to achieve reverse linkage control between "digital" and "physical". When the multi-drum washing machine is in standby mode, the display device 8 displays a main interface containing the status information of the first drum 3 and the second drum 4. The user stands in front of the washing machine and can directly click the "upper drum or first drum" icon or label on the display device 8 without bending over to operate the drum door. After receiving the user's touch operation, the display device 8 sends the user's selection information to the controller 10. The controller 10 determines that the target drum is the first drum 3 based on the selection information and detects the current status of the first drum door 5 and the equipment operating status. When it is determined that the first drum door 5 is closed, the first drum 3 is not running, the door lock is unlocked, and there is no fault alarm, the controller 10 sends an opening control command to the electric door opening mechanism 11 connected to the first drum door 5. Mechanism 11 can be any one of a micro servo motor, electromagnetic lock, or electric push rod. After receiving the control command, the electric door opening mechanism 11 drives the door hook release mechanism to automatically open the first drum door 5 to a preset angle, such as 15° to 30°, so that the user can continue to open the door and put in clothes. At the same time, the controller 10 controls the display device 8 to switch from the drum selection interface to the upper drum detailed control interface, displaying the corresponding washing program, temperature, speed, and drying options. After the user puts in the clothes, they can directly set the program and start the operation. When the user selects the "lower drum or second drum" icon on the display device 8, the controller 10 controls the electric door opening mechanism 11 corresponding to the second drum door 6 to operate according to the same logic, so that the second drum door 6 opens automatically. Through the above control method, the user can directly control the physical door to open through the digital interface, reducing the steps of the user moving to the drum door position and manually pulling the door.

[0063] Example 6: Safety control process based on interlocking logic, automatic door closing after timeout, and anti-pinch protection In this embodiment, to ensure consistency of state during bidirectional linkage and safety during automatic control, interlocking logic, automatic door closing logic after timeout, and anti-pinch protection logic are further set. When the display device 8 is currently displaying the upper drum control interface, if the user changes the operation target and manually opens the second drum door 6, the door status detection component located at the position of the second drum door 6 detects the opening signal of the second drum door 6 and sends the signal to the controller 10. The controller 10 determines that the user's current actual operation object is the second drum 4 based on the latest generated door status signal, and controls the display device 8 to immediately switch to the lower drum control interface, so that the display state is always consistent with the drum last actually operated by the user, avoiding the problem of mismatch between the screen display and the actual operation object. When the user controls the first drum door 5 or the second drum door 6 to open automatically through the display device 8, if no signal of clothes being put into the drum is detected within a preset time (e.g., 30 seconds), and If the user does not continue operating the display device 8, the controller 10 determines that the current automatic door opening may be due to a false trigger or temporary cancellation by the user, and sends a closing command to the door drive assembly 11 to slowly close the corresponding door. At the same time, the controller controls the display device 8 to return to the main interface. During the automatic door closing process, to prevent the door from pinching the user's hands or damaging clothing, anti-pinch detection components are set at the edges of the first barrel door 5 and the second barrel door 6. The anti-pinch detection components can be anti-pinch infrared sensors or capacitive touch sensor strips. When a human body or foreign object is detected blocking the door during the closing process, the anti-pinch detection components send an anti-pinch control signal to the controller 10. The controller 10 immediately stops the door closing action and controls the door drive assembly 11 to drive the door back a preset distance, such as 5mm. At the same time, the controller prompts the user to clear the foreign object on the door edge through the display device 8. After the user confirms, the closing action is executed again, thereby improving the safety and reliability of the automatic door opening and closing process.

[0064] Example 7: Screen Interaction Process of Multi-drum Washing Machine Based on Two-Way Linkage Control like Figure 4As shown, this embodiment provides a screen interaction process for a multi-drum washing machine based on bidirectional linkage control. This process uses a controller to comprehensively judge user operation behavior, door status information, and washing operation status, enabling the display device to automatically complete interface wake-up, target drum identification, program selection, parameter configuration, and multi-drum collaborative control according to the user's actual usage, thereby achieving continuous linkage between physical operation and digital interaction. In specific implementation, the multi-drum washing machine includes a first drum and a second drum, independently arranged vertically, corresponding to the upper and lower drums respectively. Each drum is equipped with an independent door, a door status detection component, a door drive component, and a corresponding control program. The display device preferably uses a color touch screen located on the front of the machine body to display the control interface of each drum and receive user input commands. The controller is connected to the display device, the door status detection component, the door drive component, and each detection sensor component, and is used to automatically match the target drum according to the user's operation behavior and control the display interface and door status to change synchronously.

[0065] In its initial state, as shown in Figure A, the multi-drum washing machine is in a standby mode with the screen off. The display output is turned off, and it only maintains a low-power detection state. At this time, the controller continuously monitors the user's proximity signal and the door status signal. When the user approaches the washing machine, the human body sensor component located on the front of the machine or near the display device detects that the user has entered the preset sensing range and sends a wake-up signal to the controller. Based on this signal, the controller controls the display device to turn from the screen-off state to the screen-on state, as shown in Figure B. The display device shows the washing machine's home screen, which displays the status information of the upper and lower drums, function access, and the drum selection area. At the same time, the controller... The device continuously monitors the user's subsequent actions. When the user directly opens a door, such as the upper door, the door status detection component located at the upper door position detects the door opening status and sends an upper door opening signal to the controller. The controller identifies the user's actual target as the upper door based on this signal and controls the display device to automatically switch to the upper door control interface. When the user does not directly open the door but clicks the upper door icon on the home screen, the controller also determines the target door based on the user's input door selection command and can control the corresponding door drive component to perform an automatic door opening action, realizing reverse linkage control of door opening triggered by screen selection.

[0066] Once the controller identifies the target drum as the upper drum, as shown in Figure C, the display device automatically enters the upper drum control interface. This interface only displays the washing program options and operating status information corresponding to the upper drum, such as AI Smart Wash, Standard Wash, Quick Wash, Intensive Wash, and Gentle Wash. Users can select the target washing program according to the type of clothing. When the user clicks on the AI ​​Smart Wash program, the controller calls up the corresponding operating parameter configuration data and controls the display device to enter the program parameter adjustment interface, as shown in Figure D. This interface displays the adjustable parameters corresponding to the current program, such as washing time, washing temperature, number of rinses, and spin speed. Users can modify the parameters according to their actual needs. After confirming the parameters, the user clicks the start button. The controller saves the current program configuration and sends a start control command to the corresponding drum drive system, causing the upper drum to enter the washing operation state.

[0067] After the upper drum starts running, as shown in Figure E, the display device switches to the running status display interface, which displays information such as the current running program, remaining running time, washing stage, and pause control entry of the upper drum in real time. At the same time, the controller continues to monitor the status of the other drum and user operation commands. Since this application adopts a multi-drum independent control structure, the operation of the upper drum will not restrict the independent operation permission of the lower drum. When the user needs to continue to use the other drum, the controller can return to the multi-drum home page interface or display the operation entry of the other drum according to the user operation. As shown in Figure F, the display device displays the lower drum operation area. The user can enter the lower drum control interface by clicking the lower drum icon, or directly open the lower drum door to trigger the "physical → digital" linkage, so that the display device automatically switches to the lower drum control interface.

[0068] When the user enters the lower drum control interface, as shown in Figure G, the user can select the corresponding washing program for the lower drum, such as the quick wash and dry program. The controller calls up the corresponding operating parameters according to the user's selection and controls the display device to enter the program confirmation interface. After the user confirms the start, the lower drum begins to run independently, as shown in Figure H. The display device displays the lower drum's operating status information, including the current operating stage, remaining time, and pause control information. At this time, the upper drum can still maintain its operating status. The two drums are independent of each other but are coordinated and managed by the same controller.

[0069] When both the upper and lower drums are running simultaneously, as shown in Figure I, the controller generates a multi-drum collaborative display interface based on the running status of the two drums. The display device simultaneously shows the running information of the upper and lower drums, including the current program, remaining time, and running status of each drum, allowing the user to obtain the overall running status of the two drums on the same interface. When either drum completes its operation or both drums complete their operation, as shown in Figure J, the controller controls the display device to enter the operation completion interface based on the completion status, prompting the user that the washing task is complete. After the user confirms or the preset time is reached, the system returns to the home page interface, as shown in Figure B, so that the user can continue to perform the next washing operation.

[0070] Through the above implementation process, the multi-drum washing machine of this application realizes a complete interactive closed loop from user proximity wake-up, target drum identification, door control, program selection, parameter configuration to multi-drum collaborative operation. Among them, the user can directly open the target drum door in the traditional way, and the display interface is triggered by the door status detection component to achieve a natural "physical to digital" interaction. Alternatively, the user can select the target drum through the color touch screen, and the controller will drive the door to open automatically, achieving a reverse "digital to physical" control. At the same time, combined with user proximity sensing, interface preloading, door interlocking, and multi-drum independent operation control logic, the display device can actively adjust the display content according to the user's behavior, avoiding the problem in traditional multi-drum washing machines where users need to repeatedly confirm the drum, switch menus, and find the corresponding door, thus improving the continuity of operation and the convenience of use.

[0071] Furthermore, during multi-drum operation, the controller continuously acquires door status information, operating status information, and user input information corresponding to the first and second drums, and dynamically adjusts the display strategy according to the current interaction status. When the user operates a certain drum, the display device prioritizes displaying the corresponding drum control interface. When both drums are running simultaneously, it automatically switches to the multi-drum operation monitoring interface, realizing intelligent switching between single-drum fine control and multi-drum overall management. This enables the multi-drum washing machine to not only complete independent washing tasks, but also provide a continuous, unified, and intuitive human-machine interaction experience according to user operation needs, further improving the interaction level of the intelligent multi-drum washing machine.
