[0035] It should be noted that the "one embodiment" or "embodiment" referred to in the description of the embodiments of the present application means a specific feature, structure or characteristic that can be included in at least one implementation manner of the present application. It should be understood that in the description of the embodiments of the present application, the terms "upper", "lower", "top", "bottom", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. Moreover, the terms "first", "second", etc. are used to distinguish similar objects and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, in the description of this embodiment, unless otherwise specified, the meaning of "a plurality" is two or more. In addition, the terms "include" and "have" and any of their variations are intended to cover non-exclusive inclusion. For example, a process, method, system or product that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0036] It should be understood that when a device or component is referred to as being "on", "adjacent to", or "connected to" another device or component, it can be directly on, adjacent to, or connected to the other device or component, or there may be intervening devices or components.

Thus, without departing from the teachings of the present application, the first component, region, layer, or part discussed below may be referred to as the second component, region, layer, or part. And when discussing the second component, region, layer, or part, it does not imply that there must be a first component, region, layer, or part in the present application.

[0037] In order to make the objectives, technical solutions, and advantages of the embodiments of the present application more clearly understood, the following further describes the embodiments of the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0038] The embodiments of the present application provide a controllable door lock system. Figure 1 It is a module schematic diagram of a controllable door lock system provided by the embodiments of the present application Figure 1 , such as Figure 1 shown. The controllable door lock system includes an instruction input module 1, a door lock module 2, a first detection module 3, a locking module 4, a central control module 5, and an execution module 6. Among them, the instruction input module 1 is communicatively connected to the central control module 5 and is used to receive the start / stop operation instruction input by the user. The door lock module 2 includes a lock piece and a lock cavity. The lock piece is used to be arranged on the door panel of the kitchen appliance, and the lock cavity is used to be arranged on the door body of the kitchen appliance. The lock piece is movably arranged in the lock cavity. The first detection module 3 is arranged on the door body and is communicatively connected to the central control module 5, and is used to send a detection signal to the central control module 5 based on the positional relationship between the lock piece and the lock cavity. The locking module 4 is arranged in the lock cavity and is communicatively connected to the central control module 5, and is used to receive the control signal sent by the central control module 5 and lock the lock piece in response to the control signal. The execution module 6 is communicatively connected to the central control module 5 and is used to receive and start or stop working based on the control signal sent by the central control module 5.

[0039] When the user inputs a start instruction through the instruction input module 1, the first detection module 3 starts to detect the positional relationship between the lock piece and the lock cavity. When it detects that the lock piece is in the lock cavity, that is, when the door of the kitchenware device is closed, the driving locking module 4 locks the lock piece in the lock cavity. Before the user inputs a pause or stop instruction through the input instruction input module 1, the locking module 4 will lock the door locking module 2. At this time, the central control module 5 controls the execution module 6 to start working, such as performing a washing operation.

[0040] Through the above settings, an additional locking module 4 is provided to lock the lock piece in the lock cavity after the door locking module 2 is closed, avoiding the situation of opening the door panel when the kitchenware device has not stopped running, thereby avoiding dangerous situations such as splashing washing water scalding the user; at the same time, reducing the phenomenon of sparking caused by suddenly opening the door, prolonging the service life of the kitchenware device, and thus optimizing the user experience.

[0041] Figure 2 It is a schematic diagram of a controllable door lock system provided by an embodiment of the present application, as Figure 2 shown, the locking module 4 includes a partition and a partition driving device. The partition driving device is connected to the partition and is used to drive the partition to perform telescopic movement and is movably arranged in the lock cavity 22.

[0042] In a possible embodiment, a locking groove is provided on the lock piece 21, which is actually a groove. In the present application, the shape of the locking groove is not limited, as long as it can be mutually locked with the partition.

[0043] When the lock piece 21 is in the lock cavity 22 and the partition is in the extended state, the partition is located in the locking groove and limits the lock piece 21. On the contrary, when the lock piece 21 is in the lock cavity 22 but the partition is in the retracted state, the partition releases the lock piece 21, and the door of the kitchenware device can be opened through a button or other switch.

[0044] Continuing as Figure 2 shown, in the embodiment of the present application, the partition driving device includes a partition driving motor and a lead screw transmission mechanism. The lead screw of the lead screw transmission mechanism is connected to the partition driving motor, and the lead screw nut of the lead screw transmission mechanism is connected to the partition to drive the partition to perform telescopic movement.

[0045] Figure 3 It is a module schematic of a controllable door locking system provided by an embodiment of the present application Figure 2 as Figure 3 shown. In order to achieve precise control of the movement of the partition, the controllable door lock system further includes a second detection module 7. The second detection module 7 is communicatively connected to the central control module 5 and is used to detect and send the current of the partition driving motor to the central control module 5.

[0046] In a possible embodiment, the second detection module 7 includes a current sensor. Specifically, a Hall effect current sensor, such as ACS712, can be selected to accurately measure the current magnitude of the partition driving motor. The second detection module 7 may further include a signal amplification circuit and an analog-to-digital conversion circuit to amplify the current signal and convert it into a digital signal adapted to the central control module 5.

[0047] In a possible embodiment, the first detection module 3 includes an infrared emitter and an infrared receiver for receiving the infrared signal emitted by the infrared emitter. When the locking piece is located between the infrared emitter and the infrared receiver, the locking piece blocks the infrared signal, and the infrared receiver detects that the door lock module 2 is in the closed state and sends the closed state to the central control module 5.

[0048] In a possible embodiment, the controllable door locking system further includes a voice prompt module 8. The voice prompt module 8 is communicatively connected to the central control module 5 and is configured to issue a voice prompt in response to a control signal from the central control module 5.

[0049] Taking a dishwasher as an example, through the above settings, when the user needs the dishwasher to perform different functions, the user can select the corresponding washing program. After the user selects the program and presses the start button, at this time, the infrared receiver will detect the locking piece by means of whether the infrared signal is blocked. If the locking piece is not detected in the lock cavity, the central control module 5 will drive the voice prompt module 8 to broadcast "the door is not closed", and the washing program will not start.

[0050] If the infrared receiver detects that the locking piece is already in the lock cavity, the central control module 5 sends a control signal to the partition driving motor. The partition driving motor rotates forward to drive the partition to move left (or right) to enclose the locking piece. When the partition motor runs to the leftmost (or rightmost) position, the partition driving motor will stall, and the current will increase. The current sensor detects the current. When the current exceeds the set value, the central control module 5 stops driving the partition motor, and at this time, the execution module 6 can start to work.

[0051] When the lock piece is locked, the dishwasher door cannot be opened through the door handle, effectively preventing the risk of the kitchenware equipment being opened during operation. If the user needs to add dishes during the washing process, the user needs to select the pause program key on the control panel of the dishwasher. At this time, the central control module 5 will stop the washing pump from cleaning and simultaneously drive the partition drive motor to reverse. The reverse rotation of the partition drive motor drives the partition to move to the right (or left) side. When the partition moves to the rightmost (or leftmost) side, the partition drive motor will be blocked, the current will increase, and the current sensor will detect the current. When the current exceeds the set value, the central control module 5 will stop driving the partition drive motor. At this time, the central control module 5 will drive the voice prompt module 8 to broadcast "the door can be opened". At this time, the user can open the door normally. After adding the dishes, press the start button, and at this time, the process repeats the door lock locking process at the start and circulates.

[0052] In another possible embodiment, the first detection module 3 may further include a magnetic member and a magnetic sensor for detecting magnetic field changes. The magnetic member is disposed on the door panel, and the magnetic sensor is disposed on the door body.

[0053] When the lock piece is located in the lock cavity, the magnetic member is close to the magnetic sensor, and the magnetic sensor detects that the door lock module 2 is in the closed state and sends the closed state to the central control module 5.

[0054] Through the above settings, the first detection module 3 can detect whether the lock piece is located in the lock cavity by using the magnetic field change near the door body. Compared with the detection method of infrared signals, the magnetic field change is more sensitive. At the same time, in order to ensure the sealing performance after the door body is closed, the door panel and the door body are generally set to be closed in a magnetic adsorption manner. In this case, there is no need to additionally set a magnetic member, and the magnetic members on the door panel and the door body are directly used for detection, saving the installation cost, simplifying the structure of the kitchenware equipment, and reducing the maintenance cost.

[0055] In a possible embodiment, the locking module 4 is detachably connected to the kitchenware equipment. When an emergency such as a power outage occurs in the user's home, there is no need to worry about not being able to open the door body of the kitchenware equipment. It only needs to directly remove the locking module 4 from the door body, and the door body can be opened arbitrarily after removal.

[0056] In a possible embodiment, the controllable door locking system further includes a third detection module 9. Further, the instruction input module 1 specifically includes a touch button and a display screen provided on the kitchenware equipment.

[0057] The third detection module 9 is communicatively connected to the central control module 5 and is configured to detect the working state of the execution module 6 and send it to the central control module 5. The touch button is communicatively connected to the central control module 5 and is configured to receive the start / stop operation instruction input by the user and output it to the central control module 5. The display screen is communicatively connected to the central control module 5 and is configured to respond to the control signal of the central control module 5 and display the working state of the execution module 6, such as paused, working, and remaining working time, etc.

[0058] With the above settings, the user can more intuitively see the working state of the execution module 6, which is convenient for the user to operate. Taking a dishwasher as an example, when the user sees the prompt "working", they can directly click the pause button to add dishes and chopsticks midway, instead of first trying to open the door and only realizing that the dishwasher is still working after the door cannot be opened.

[0059] The embodiment of the present application further provides a dishwasher, which includes the above-mentioned controllable door lock system.

[0060] By setting the controllable door lock system, it is possible to prevent the door panel from being opened when the dishwasher has not stopped running, thereby avoiding dangerous situations such as washing water splashing out and scalding the user. When the dishwasher door is suddenly opened during operation, the central control module 5 of the dishwasher will cut off the power supply of the washing pump circuit to prevent the washing pump from continuing to rotate and causing harm to the user. When the door is opened and the power is cut off, the relay contacts are switched, and there is a sparking phenomenon, which seriously affects the service life of the relay and further affects the life of the dishwasher main control board. By setting the controllable door lock system, the dishwasher door can be opened only after the operation stops, reducing the phenomenon of sparking caused by sudden door opening, extending the life of the dishwasher, and thus optimizing the user experience.
