[0044] To enable those skilled in the art to better 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 them. 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.

[0045] 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.

[0046] The dishwasher door is connected to the cabinet via a buffer assembly to ensure the safety of opening the door and to maintain the required opening angle. A handle is typically provided on the door for easy opening and closing.

[0047] In related technologies, dishwashers and other electrical appliances are equipped with door opening devices. During operation, the door opening device is locked to the main motor to ensure safety. When the appliance is not in operation, the user can unlock the door opening device to open the main motor. However, the door opening devices in these related technologies are complex in structure, inconvenient to operate, and negatively impact user experience, thus requiring improvement.

[0048] Based on the above-mentioned technical problems, this application provides a door opening device and an electrical device, which aims to at least partially solve the technical problems of complex structure and inconvenient operation of the door opening device, so as to improve the user experience.

[0049] In a first aspect of this application, a door opening device is provided. Figure 1 A schematic diagram of the door opening device in one or more embodiments of this application is shown. Figure 2 It shows Figure 1 A schematic diagram of the explosion. Combined with... Figure 1 as well as Figure 2 The door opening device includes a door body 100, a key body 200, a sliding member 300, and a door lock assembly 500. The key body 200 is elastically connected to the door body 100 and can reciprocate along the thickness direction of the door body 100. A first driving part 201 is provided on the inner side of the key body 200. The sliding member 300 is reciprocally connected to the door body 100 along the length direction of the door body 100. A second driving part 301 is provided on the sliding member 300. At least a portion of the inclined surfaces of the second driving part 301 and the first driving part 201 are engaged. The door lock assembly 500 includes a door hinge 501 and a door latch 502. The door hinge 501 is rotatably connected inside the door body 100. The door hinge 501 is connected to the sliding member 300 through a rope 400. The door latch 502 is connected to the door hinge 501 and rotates synchronously with the door hinge 501.

[0050] The door opening device provided in this application has a key body 200 that is elastically connected to the door body 100 and can reciprocate along the thickness direction of the door body 100. A first driving part 201 is provided on the inner side of the key body 200, and a second driving part 301 is provided on the sliding member 300. At least a portion of the inclined surfaces of the second driving part 301 and the first driving part 201 engage. Therefore, when a user presses the key body 200, the inclined surfaces of the second driving part 301 and the first driving part 201 engage, causing the sliding member 300 to move along the length direction of the door body 100. The door hinge 501 of the door lock assembly 500 is connected to the sliding member 300 via the rope 400. When the sliding member 300 moves along the length of the door body 100, the sliding member 300 drives the rope 400 to move, thereby causing the door hinge 501 to rotate inside the door body 100. Since the door latch 502 is connected to the door hinge 501 and rotates synchronously with the door hinge 501, the door latch 502 rotates synchronously when the door hinge 501 rotates, so that the door latch 502 can unlock with the main unit of the electrical device, thereby allowing the user to easily open the door body 100 to the required angle.

[0051] The door opening device provided in this application only requires pressing the key body 200, and the door body 100 can be unlocked through the linkage of the key body 200, the sliding member 300, and the door hinge 501. It has a simple structure, is easy to operate, and has excellent practicality. The specific details of the door opening device are further described below with reference to the accompanying drawings.

The second driving block 302 has a second inclined surface that engages with the first inclined surface, and is configured as a second driving part 301 of the slider 300. When the key body 200 is pressed, the key body 200 moves. Through the engagement of the inclined surfaces of the first driving block 205 and the second driving block 302, the two sliders 300 are driven to move towards the key body 200, i.e., the two sliders 300 move closer together. In another embodiment, the first driving block 205 is provided on one of the two side walls along the length of the receiving groove 203. Correspondingly, a slider 300 is also provided. When the key body 200 is pressed, the key body 200 moves. Through the inclined surface cooperation of the first driving block 205 and the second driving block 302, the slider 300 is driven to move towards the key body 200.

[0058] Figure 8 This diagram shows the assembly of the slider 300 on the pull plate 102. Figure 9 It shows Figure 8 A schematic diagram of the explosion. Combined with... Figure 8 as well as Figure 9 According to one embodiment of this application, a groove 1025 is provided in the pull plate 102, and two sliding members 300 are slidably connected in the groove 1025, thereby providing guidance for the movement of the sliding members 300. In a specific implementation, the groove 1025 is provided in the second side portion 1022 of the pull plate 102, and both sides of the groove 1025 are open in the length direction, so that the sliding members 300 can pass through the groove 1025 along the length direction of the groove 1025. During the movement of the sliding members 300, at least a portion of the sliding members 300 is disposed in the groove 1025 to ensure the direction of movement of the sliding members 300.

[0059] Combination Figure 8 as well as Figure 9According to one embodiment of this application, the bottom wall of the slide 1025 is connected to a limiting member 1026, and the sliding member 300 is provided with a limiting hole 303105 extending along the length direction of the door body 100, with the limiting member 1026 disposed in the limiting hole 303105. During the movement of the sliding member 300, the limiting member 1026 is always in the limiting hole 303105 of the sliding member 300. When the sliding member 300 is at its extreme position away from the key body 200, the limiting member 1026 abuts against the side of the limiting hole 303105 facing the key body 200. When the sliding member 300 returns to its initial position, the limiting member 1026 abuts against the side of the limiting hole 303105 facing away from the key body 200. That is, the setting of the limiting member 1026 can ensure that the sliding member 300 moves to the designed position.

[0060] Combination Figure 8 as well as Figure 9 In one embodiment, the limiting hole 303105 can be an oval hole with its length direction being the length direction of the door body 100.

When the sliding member 300 is at its extreme position away from the key body 200, the first limiting post 10261 abuts against the side of the limiting hole 303105 facing the key body 200. When the sliding member 300 returns to its initial position, the second limiting post 10262 abuts against the side of the limiting hole 303105 facing away from the key body 200. That is, the setting of the two limiting posts can ensure that the sliding member 300 moves to the designed position. In another embodiment, the limiting hole 303105 may also be a rectangular hole, and the limiting member 1026 may also include only one limiting post. This application does not impose any restrictions on this.

[0061] It should be noted that the first limiting post and the second limiting post 10262 in this application are both integrally formed on the second side 1022. At least one of the first limiting post 10261 and the second limiting post 10262 can be connected to the first side 1021 by screws or other components to strengthen the structure of the pull plate 102.

[0062] Figure 10 A schematic diagram of the slider 300 is shown, combined with Figure 10 According to one embodiment of this application, a first hook 304 is provided at the end of the slider 300 away from the keyway, and one end of the rope 400 is hung on the first hook 304 of the slider 300. The rope 400 can be provided one-to-one with the slider 300. When there are two sliders 300, there are correspondingly two ropes 400. The other ends of the two ropes 400 are connected to the two ends of the door hinge 501, so that the door hinge 501 can be driven to rotate by the movement of the two ropes 400, thereby improving the balance of force on the door hinge 501.

[0063] Figure 11 It shows Figure 8 The enlarged diagram at point A, combined with Figure 10 According to one embodiment of this application, at least one rotatable roller 700 is provided inside the pull plate 102. The roller 700 is arranged on the extension path of the rope 400 to ensure the tension of the rope 400 while changing the extension direction of the rope 400. In a specific implementation, a rotatable roller 700 is provided inside the end of the pull plate 102 in the length direction. The other end of the rope 400 passes around the roller 700 and is connected to the end of the door hinge 501. The roller 700 can be connected to the inner side of the second side portion 1022 of the pull plate 102. A groove is provided on the circumference of the roller 700. The rope 400 is wound around the groove of the roller 700 to limit the position of the rope 400 on the roller 700 and prevent the rope 400 from deviating during movement.

[0064] Combination Figure 2 According to one embodiment of this application, the door panel 101 includes an outer door panel 1011 and an inner door panel 1012 connected to each other. The pull plate 102 is connected to the outside of the outer door panel 1011. An accommodating space is formed between the outer door panel 1011 and the inner door panel 1012. The door hinge 501 is rotatably connected to the accommodating space through a plurality of spaced seats 103. Two door latches 502 are also provided opposite to each other. The two door latches 502 are fixedly connected to the door hinge 501. The inner door panel 1012 is provided with a through hole 1013 for the door latches 502 to rotate. With the door panel 101 closed to the host, the door latch 502 passes through the through hole 1013 on the inner door panel 1012 and latches onto the host. At this time, the door latch 502 is in the locked position, keeping the door panel 101 closed on the host. When the door hinge 501 is rotated, the door latch 502 rotates synchronously with the door hinge 501. The door latch 502 flips in the corresponding through hole 1013 and is in the unlocked position, so that the door latch 502 is unlocked from the host, allowing the user to open the door 100.

[0065] Combination Figure 2 According to one embodiment of this application, the door opening device further includes a drive member 800, which is connected to the door hinge 501 and to the rope 400. Two drive members 800 may be provided corresponding to the rope 400. When a user presses a button, it drives a slider 300 to move along the length of the door 100. The slider 300 drives the rope 400 to move. Since the drive member 800 is connected to the door hinge 501 and to the rope 400, the moving rope 400 causes the drive member 800 and the door hinge 501 to rotate, thereby driving the door latch 502 to flip, thus unlocking the door latch 502.

[0066] Figure 12 It shows Figure 2A structural diagram of part of the central door lock assembly 500. Figure 13 Show Figure 2 A structural schematic diagram of the drive unit 800. (Combined with...) Figure 12 as well as Figure 13 According to one embodiment of this application, the drive member 800 is provided with an assembly hole 8011023 sleeved on the door hinge 501. The side wall of the assembly hole 8011023 is provided with a positioning groove 802. The door hinge 501 is provided with a flange 503, which is fitted into the positioning groove 802. The flange 503 can restrict the rotation of the drive member 800 on the door hinge 501 so that the drive member 800 and the door hinge 501 are relatively fixed and can rotate synchronously.

[0067] Combination Figure 12 as well as Figure 13 According to one embodiment of this application, the side wall of the positioning groove 802 is open, and the door latch 502 is attached to the open side of the positioning groove 802 of the drive member 800. When the drive member 800 is assembled onto the door hinge 501, the drive member 800 is pushed in from the end of the door hinge 501. During the process of the drive member 800 being attached to the door latch 502, the flange 503 enters into the positioning groove 802 through the open side of the positioning groove 802, so that the drive member 800 is assembled onto the door hinge 501.

[0068] Combination Figure 13 According to one embodiment of this application, one end of the driving member 800 is provided with the above-mentioned mounting hole 8011023, and the other end of the driving member 800 is provided with a second hook portion 803, and the second end of the rope body 400 is connected to the second hook portion 803 of the driving member 800.

[0069] Combination Figure 2 According to one embodiment of this application, the door opening device further includes a second elastic member 900. Figure 14 It shows Figure 2 A schematic diagram of the structure of the second elastic element 900. Figure 15 An assembly diagram of the second elastic element 900 is shown, in conjunction with... Figure 14 as well as Figure 15 The second elastic element 900 can be a torsion spring, which is sleeved on the door hinge 501. Both ends of the second elastic element 900 are connected to the drive element 800 and the door body 100, respectively. During the process of pressing the key body and driving the door latch 502 to flip and unlock, the second elastic element 900 deforms. After the action on the key body 200 is released, the second elastic element 900 returns to its original deformation, driving the door latch 502 back to its initial position. This then drives the door hinge 501 and the drive element 800 back to their original positions, and drives the rope 400 to move away from the key body 200, thereby causing the sliding element 300 to return to its initial position.

[0070] CombinationFigure 14 as well as Figure 15 According to one embodiment of this application, the second elastic member 900 has a first free end 901 and a second free end 902. The first free end 901 of the second elastic member 900 is bent to form a bent portion 903, which abuts against the side of the driving member 800. The inner side of the outer door panel 1011 is provided with a support seat 104 for supporting the door hinge 501. A limiting hole 303105 is provided on the support seat 104. The second free end 902 of the second elastic member 900 is inserted into the limiting hole 303105 of the support seat 104. Under the condition that the driving member 800, the door latch 502 and the door hinge 501 rotate synchronously, the first free end 901 of the second elastic member 900 deforms; or, the first free end 901 of the second elastic member 900 restores its deformation so that the driving member 800, the door latch 502 and the door hinge 501 synchronously reset and rotate.

[0071] The opening and closing principle of the door opening device provided in this application is as follows:

[0072] With the door 100 open, the user holds the pull plate 102 and presses the key body 200. The first elastic element 600 compresses and deforms, and the key body 200 drives the sliding element 300 to move along the length of the door 100 towards the key body 200. The sliding element 300 drives the rope 400 to move towards the key body 200, thereby driving the drive element 800, the door hinge 501, and the door latch 502 to rotate synchronously, so that the door latch 502 unlocks the main unit of the electrical equipment. At the same time, the second elastic element 900 compresses and deforms, and the user applies force to the pull plate 102 to open the door 100 to the desired angle. During the opening process, the user can release the key body 200, and under the action of the first elastic element 600 restoring its deformation, the key body 200 returns to its initial position. Under the action of the second elastic element 900, the drive element 800, door hinge 501, and door latch 502 return to their initial positions, simultaneously driving the rope 400 and sliding element 300 to return to their initial positions. With the door 100 closed, the user holds the pull plate 102 and presses the key 200, repeating the above operation to put the door latch 502 in the unlocked position. The user then applies force to the pull plate 102 to close the door 100. Subsequently, the user releases the key 200, and under the action of the first elastic element 600 restoring its deformation, the key 200 returns to its initial position. Under the action of the second elastic element 900, the drive element 800, door hinge 501, and door latch 502 return to their initial positions, so that the door 100 is closed on the host.
