[0041] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] Dishwashers are kitchen appliances that automatically clean dishes and are gradually becoming a common household appliance. They typically include a drying function to quickly dry dishes after washing, preventing bacterial growth in a damp environment.

[0043] After the dishwasher's washing cycle ends, a higher temperature is required for drying. To address the issue of high energy consumption, related technologies have implemented a system where the dishwasher door automatically opens to a certain angle after the washing cycle ends, utilizing air exchange to dry the dishes inside the machine. This allows for the rapid expulsion of hot and humid air from the dishwasher's interior, achieving a better drying effect and reducing energy consumption.

[0044] In related technologies, dishwasher doors are connected to the cabinet via a buffer to ensure safety when the door opens. However, if the buffer fails, it cannot provide the necessary tension. If the dishwasher door opens automatically, it will fall rapidly, posing a safety hazard and potentially injuring users, children, or pets. While dishwashers can achieve the purpose of drying, they pose significant safety risks and negatively impact the user experience.

[0045] To address the aforementioned technical problems, this application provides an electrical appliance designed to at least partially prevent the potential for the appliance's door to fall after automatic opening, thereby improving safety and user experience. The electrical appliance described in this application can be a dishwasher, or other electrical appliances with openable doors, such as disinfection cabinets or integrated stoves, to prevent safety hazards caused by door falls. The following explanation uses a dishwasher as an example to illustrate the motor device.

[0046] Figure 1 A schematic diagram of the structure of an electrical device according to one or more embodiments of this application is shown. Figure 2 It shows Figure 1 Side view diagram, Figure 3 It shows Figure 1 A structural diagram showing the locking element in a separated state from the hinge. Figure 4 It shows Figure 1 A schematic diagram of the locking element abutting against the hinge. (Combined with...) Figures 1-4The electrical equipment provided in this application includes a door 100, a cabinet 200, and a locking member 600. The cabinet 200 is provided with a loading port. The door 100 is closably connected to the loading port of the cabinet 200 via a hinge 300 to open or close the loading port of the door 100. In addition, the hinge 300 is provided with a locking part 301. The locking member 600 is rotatably connected to the cabinet 200. In the event of failure of the buffer 400, at least a portion of the locking member 600 rotates and abuts against the locking part 301 on the hinge 300 to prevent the door 100 from opening, thereby avoiding the safety hazard caused by the door 100 falling due to the failure of the buffer 400, and improving safety. The specific details of the electrical equipment are now further described with reference to the accompanying drawings.

[0047] Combination Figure 1 as well as Figure 2 When the electrical appliance of this application is a dishwasher, the front end of the dishwasher cabinet 200 is open to form the dishwasher inlet, and the door 100 can close the dishwasher inlet to form a sealed space inside the dishwasher for running the dishwasher's washing program on the tableware.

[0048] Combination Figures 1-4 The side of the door 100 is connected to the cabinet 200 via a hinge 300, and the top of the door 100 is connected to the door opening component 500 installed on the cabinet 200. The door opening component 500 can automatically open the door 100 to a certain angle after the dishwasher has finished the washing program, so that the door 100 is suspended at a certain angle. Air exchange is used to dry the dishes inside the cabinet 200, so as to quickly expel the hot and humid air inside the dishwasher, thereby achieving a better drying effect and reducing energy consumption.

[0049] Combination Figures 1-4 The electrical equipment of this application also includes a buffer 400, which is at least partially elastic, and its two ends are respectively connected to the door 100 and the cabinet 200. Because the buffer 400 is at least partially elastic, and its two ends are respectively connected to the door 100 and the cabinet 200, when the door 100 and the cabinet 200 move relative to each other, the elastic portion of the buffer 400 deforms synchronously and moves with the door 100 to provide a buffering force to the door 100 to prevent it from falling.

[0050] Combination Figures 1-4The buffer 400 includes an elastic body 401 and a rope 402, which are connected to connect the door 100 and the cabinet 200. During the opening and closing of the door 100, the elastic body 401 of the buffer 400 deforms accordingly to drive the rope 402 to reciprocate. Alternatively, the rope 402 may also have a certain degree of elasticity, but its elastic deformation capacity is less than that of the elastic body 401, so the rope 402 can also deform accordingly during the opening and closing of the door 100.

[0051] Combination Figures 1-4 In one embodiment, one end of the elastic body 401 is connected to the cabinet 200, and one end of the rope 402 is connected to the other end of the elastic body 401. The other end of the rope 402 is connected to the door 100, i.e., the door 100 and the cabinet 200 are connected by a combination of an elastic body 401 and a rope 402. In another embodiment, multiple elastic bodies 401 may be provided, and ropes 402 are connected between adjacent elastic bodies 401. The door 100 and the cabinet 200 are connected by a combination of multiple elastic bodies 401 and ropes 402. During the opening and closing of the door 100, the multiple elastic bodies 401 of the buffer 400 deform accordingly to drive the rope 402 to reciprocate.

[0052] Combination Figures 1-4 The cabinet 200 of this application has a base 201 at the bottom and a connector 202 on the base 201. The connector 202 can be a rod structure and is located on the side of the base 201 near the door 100. The elastic body 401 can be a spring, with one end connected to the connector 202 and the other end extending horizontally away from the connector 202.

[0053] Combination Figures 1-4 The electrical device of this application also includes a support member connected to the cabinet 200. The rope 402 passes around the support member and is connected to the door 100. During the opening and closing of the door 100, the reciprocating movement of the rope 402 generates friction with the support member to balance the weight of the door 100, allowing it to accommodate heavier doors. Furthermore, the support member restricts and guides the rope 402, keeping it taut and ensuring it moves only along a set path, thus preventing interference between the rope 402 and other parts of the dishwasher during movement.

[0054] Combination Figures 1-4In one embodiment, the support member of this application can be a wheel structure, rotatably connected to the cabinet 200. The rope 402 and the support member generate rolling friction, which reduces the frictional force between the rope 402 and the support member, but also allows the rope 402 to move smoothly on the support member, reducing wear and tear and increasing its service life. In another embodiment, the support member can also be fixedly mounted on the cabinet 200, with the rope 402 and the support member generating static friction to increase the frictional force between them.

[0055] The application can provide multiple support members. Through the friction between the multiple support members and the rope 402, it can adapt to the opening and closing of the door 100 with different self-weights and keep the rope 402 taut, so that the rope 402 can only move on the set track, so as to avoid the rope 402 interfering with other parts of the dishwasher during the movement.

[0056] Combination Figures 1-4 In one embodiment, the present application provides two support members, namely a first support member 203 and a second support member 204. Both the first support member 203 and the second support member 204 are connected to the base 201 of the cabinet 200. The first support member 203 and the connector 202 are located on opposite sides of the base 201 of the cabinet 200 in the horizontal direction. The second support member 204 is connected above the connector 202 and the first support member 203. One end of the rope 402 is connected to the elastic body 401, and the other end of the rope 402 passes sequentially around the first support member 203 and the second support member 204, and is connected to the hinge 300. The rope 402 located on the first support member 203 and the second support member 204 is arranged at an angle. In another embodiment, the other end of the rope 402 can also be connected to the side of the door 100; this is not a limitation.

[0057] Figure 5 It shows Figure 1 A schematic diagram of the hinge structure. (Combined with...) Figures 3-5 The hinge 300 of this application is rotatably connected to the side of the cabinet 200 via a first pin 304. A connecting plate 302 is provided on one side, which is attached to the edge of the door 100 by screws or other components. A hook 303 is provided on the other side, and the other end of the rope 402 of the buffer member 400 is hooked into the hook 303 of the hinge 300 to achieve the assembly of the buffer member 400 in the electrical equipment. During the opening of the door 100, the door 100 drives the hinge 300 to rotate around the first pin 304, and the buffer member 400's cushioning restraint allows the door 100 to hover at the user's desired opening degree.

[0058] Combination Figure 3 as well as Figure 4In some embodiments, the locking member 600 is a block structure, which may be fan-shaped, and its central axis is rotatably connected to the side of the cabinet 200 via a second pin 601. The locking member 600 is disposed above at least a portion of the hinge 300. Under the condition that the buffer member 400 fails, the locking member 600 rotates around the second pin 601, and the periphery of the locking member 600 abuts against the locking portion 301 on the hinge 300.

[0059] To reduce noise generated when the locking member 600 contacts the hinge 300, in some embodiments, at least a portion of the locking member 600 is elastic, allowing the locking member 600 to elastically contact the hinge 300, thereby reducing noise and improving user experience. Specifically, an elastic block can be provided on the periphery of the locking member 600, which can be adhered to the periphery of the locking member 600 to allow the periphery of the locking member 600 to elastically contact the hinge 300.

[0060] Combination Figures 1-4 In order to enable the locking member 600 to rotate in response to the failure of the buffer member 400, in one embodiment, the electrical device further includes a support assembly 700, through which the locking member 600 and the buffer member 400 are linked. Now, by way of appendix... Figure 3 Appendix Figure 4 and appendix Figure 6 Further details regarding the supporting components are described.

[0061] Figure 6 It shows Figure 1 A structural diagram of the supporting components. (Combined with...) Figure 3 , Figure 4 as well as Figure 6 In some embodiments, the support assembly 700 includes a fixing member 701 and a moving member 702. The fixing member 701 is connected to the cabinet 200, the bottom end of the moving member 702 is supported on the buffer member 400, the top end of the moving member 702 moves through the fixing member 701, and the locking member 600 is supported by the top end of the moving member 702. Under the condition that the buffer member 400 does not malfunction, the buffer member 400 supports and limits the moving member 702, and the locking member 600 is pushed to a certain height by the top end of the moving member 702, thus locking the device. When component 600 separates from hinge 300, door 100 can open and close normally. Under the condition that buffer component 400 fails, due to the lack of buffer component 400 restricting the moving component 702, the moving component 702 rotates downward. The top of locking component 600 separates from the top of moving component 702. Under its own weight, locking component 600 rotates and abuts against the locking part 301 on hinge 300 to prevent door 100 from opening, thereby avoiding the safety hazard caused by door 100 falling due to the failure of buffer component 400 and improving safety.

[0062] Combination Figure 3 as well as Figure 4 In some embodiments, the bottom of the fastener 701 can be connected to the side wall of the cabinet 200 by a screw or other connector 202, and the top of the fastener 701 extends towards the top of the cabinet 200. Furthermore, the bottom cross-sectional dimension of the fastener 701 can be larger than the top cross-sectional dimension to improve the reliability of the fastener 701's assembly on the cabinet 200. For example, the fastener 701 can be triangular or trapezoidal, etc., without limitation.

[0063] Combination Figure 3 , Figure 4 as well as Figure 6 In some embodiments, the fixing member 701 is provided with a protrusion 704, which is positioned above the buffer member 400. The protrusion 704 has a through hole 703 through which the moving member 702 can move. The protrusion 704 of the fixing member 701 ensures that the moving member 702 and the buffer member 400 are approximately on the same plane, so that the moving member 702 is only subjected to the force of this plane. This allows the moving member 702 to respond to the buffer member 400 in a timely manner, and ensures that the locking member 600 can respond to rotation in a timely manner in the event of abnormal failure of the buffer member 400.

[0064] Combination Figure 6 In specific implementation, the movable part 702 is generally square in shape, and at least part of the side of the fixed part 701 is provided with a box structure. The box structure can be configured as a protrusion 704. The through hole 703 of the protrusion 704 is a square mechanism that matches the movable part 702. The length of the movable part 702 needs to be greater than the length of the protrusion 704 so that both ends of the movable part 702 can extend out of the protrusion 704 of the fixed part 701.

[0065] Combination Figure 3 , Figure 4 as well as Figure 6 In some embodiments, the bottom end of the movable member 702 is provided with a rotatable support wheel 705, which is supported on the buffer member 400. The support wheel 705 can be supported on the rope 402 between the second support member 204 and the hinge 300. Since the support wheel 705 can rotate on the movable member 702, rolling friction is formed between the rope 402 and the support wheel 705, thereby reducing wear on the rope 402 and improving its service life while supporting the movable member 702. In other embodiments, the support wheel 705 can also be fixedly connected to the bottom end of the movable member 702, and static friction is formed between the rope 402 and the support wheel 705. It should be noted that the support wheel 705 can also be supported on the rope 402 between the first support member 203 and the second support member 204; this is not a limitation.

[0066] Figure 7 The diagram shows the assembly of the locking component and the first driving component. Figure 7 In order to respond to the failure of the buffer 400 and enable the locking member 600 to rotate accordingly, in another embodiment, the electrical device further includes a first drive member 800, which has a rotatable output end. The locking member 600 is connected to the output end of the first drive member 800. When the buffer 400 does not fail abnormally, the locking member 600 can be separated from the hinge 300 by the restriction of the first drive member 800, allowing the door 100 to open and close normally. When the buffer 400 fails abnormally, the output end of the first drive member 800 is controlled to rotate, thereby driving the locking member 600 to rotate. The locking member 600 abuts against the locking part 301 on the hinge 300 to prevent the door 100 from opening, thus avoiding the safety hazard caused by the door 100 falling due to the failure of the buffer 400 and improving safety. The first drive member 800 can be a motor or other motion mechanism with a rotatable output end, and it can be placed on the cabinet 200.

[0067] Figure 8 The diagram shows the assembly of the locking element and the second driving element, combined with... Figure 8 In order to respond to the failure of the buffer 400 and allow the locking member 600 to rotate accordingly, in other embodiments, the electrical device further includes a second drive member 900, which has an output end capable of linear reciprocating motion. The locking member 600 is supported on the output end of the second drive member 900. Under normal conditions where the buffer 400 does not fail, the locking member 600 can be separated from the hinge 300 by the support and restriction of the output end of the second drive member 900, allowing the door 100 to open and close normally. Under conditions of abnormal failure of the buffer 400, the output end of the second drive member 900 is retracted, the locking member 600 and the top of the moving member 702 separate, and the locking member 600 rotates under its own weight and abuts against the locking part 301 on the hinge 300 to prevent the door 100 from opening, thus avoiding the safety hazard caused by the door 100 falling due to the failure of the buffer 400 and improving safety. The second drive component 900 can be a motion mechanism such as a motor with a linear reciprocating motion output end, and it can be placed on the cabinet 200.

[0068] Figure 9 A schematic diagram showing the connection between the detection component and the driving component is provided. Figure 9To enable the first drive member 800 or the second drive member 900 to respond to the buffer member 400, the electrical device of this application further includes a detection component 1000 for confirming the state of the buffer member 400. This detection component 1000 is connected to the first drive member 800 or the second drive member 900. In the event of an abnormal failure of the buffer member 400, the detection component 1000 sends an abnormal signal to the first drive member 800 or the second drive member 900. Upon receiving the abnormal signal, the first drive member 800 or the second drive member 900 controls its output terminal to operate, causing the locking member 600 to rotate and abut against the locking portion 301 on the hinge 300, thereby preventing the door 100 from opening and avoiding the safety hazard caused by the door 100 falling due to the failure of the buffer member 400, thus improving safety.

[0069] Figure 10 A schematic diagram showing the connection between the controller and the detection components and drive units is provided. Figure 10 In another embodiment, the electrical device further includes a controller 1100, which is connected to the detection component 1000 and the first drive component 800 or the second drive component 900. When the buffer component 400 malfunctions, the detection component 1000 sends a signal to the controller 1100. Upon receiving the abnormal signal, the controller 1100 sends a working command to the first drive component 800 or the second drive component 900 to control the output of the first drive component 800 or the second drive component 900. The locking component 600 rotates and abuts against the locking part 301 on the hinge 300 to prevent the door 100 from opening, thus avoiding the safety hazard caused by the door 100 falling due to the failure of the buffer component 400 and improving safety.

[0070] As for the specific structure of the detection component 1000, the detection component 1000 can be a vision sensor, which can simultaneously collect image information of the buffer 400 to determine whether the buffer 400 is abnormally malfunctioning. It can pre-collect normal image information of the buffer 400 as reference information, compare the collected image information with the reference information, and if they do not match, it is determined that the buffer 400 is abnormally malfunctioning. Then the detection component 1000 sends a signal to the controller 1100. Additionally, the detection component 1000 can also be a pressure sensor. When the buffer 400 is working normally, the buffer 400 is in a tensioned state. If the tension of the buffer 400 suddenly drops to a very small value or even zero, it indicates that the buffer 400 has broken, indicating that the buffer 400 has malfunctioned. The detection component 1000 then sends a signal to the controller 1100. After receiving the abnormal signal, the controller 1100 issues a working command to the first drive component 800 or the second drive component 900 to control the output end of the first drive component 800 or the second drive component 900 to move. The locking component 600 rotates and abuts against the locking part 301 on the hinge 300 to prevent the door 100 from opening, thereby avoiding the safety hazard caused by the door 100 falling due to the failure of the buffer 400 and improving safety.

[0071] The buffer 400 in this application is provided in two sets, which are respectively placed on both sides of the cabinet 200. Correspondingly, the locking components are also provided in two sets. The two sets of locking components operate synchronously to further avoid the safety hazards caused by the door 100 falling due to the failure of the buffer 400, so as to improve safety.
