[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This embodiment discloses a dishwasher with an automatic door opening function, referring to... Figure 1 , Figure 2 As shown, the device includes a housing 1 and a door 3. The door 3 is rotatably connected to the opening of the housing 1. A locking component 4 is installed on the side of the door facing the housing 1. A second locking component 5 is rotatably connected to the housing 1. The second locking component 5 can lock with the first locking component 4. The second locking component 5 can be unlocked by rotating.

[0027] The dishwasher in this embodiment also includes a linkage component 6, a linkage shaft 7, a linkage block 8, and a trigger component 9. The linkage shaft 7 is rotatably connected to the top of the cabinet 1, and both ends of the linkage shaft 7 extend along the width direction of the dishwasher. The linkage block 8 is fixedly connected to the end of the linkage shaft 7, and the linkage component 6 is drivenly connected between the linkage block 8 and the second locking component 5. The linkage component 6 enables the linkage shaft 7 and the second locking component 5 to rotate in a coordinated manner.

[0028] The trigger element 9 is fixedly connected to the linkage shaft 7. The trigger element 9 extends outward from the linkage shaft 7 and tilts upward to form a structure that can trigger a press. The downward swing of the trigger element 9 can drive the locking element 2 5 to rotate, and the locking element 2 5 and the locking element 1 4 can unlock each other.

[0029] The dishwasher in this embodiment also includes a driver 2 and a pull cord 13. The two ends of the pull cord 13 are connected to the driver 2 and a trigger 9, respectively. The driver 2 can exert a pulling force on the pull cord 13, thereby pulling the pull cord 13 and causing the trigger 9 to deflect. The deflection of the trigger 9 under tension drives the linkage shaft 7, which in turn drives the linkage block 8, linkage member 6, and locking member 2 5, unlocking locking member 1 4 and locking member 2 5. After unlocking, the door can be automatically opened by pushing the elastic pin between the door body 3 and the cabinet body 1.

[0030] The drive unit 2 can be controlled by the control module inside the dishwasher to achieve automatic door opening. For example, at the end of the washing process, the door 3 can be opened to allow the hot and humid air inside the dishwasher cavity to escape, which is beneficial for the drying process inside the dishwasher.

[0031] Reference Figure 2 As shown, one side of the trigger 9 is fixedly connected to the linkage shaft 7, while the other side is tilted upwards away from the linkage shaft 7. A guide wheel 14 is provided on the lower side of the trigger 9, and the guide wheel 14 is rotatably connected to the upper part of the housing 1, allowing for smooth rotation. The first end 131 of the pull rope 13 is connected to the trigger 9, passes downwards around the guide wheel 14, and the second end 132 of the pull rope 13 is connected to the driver 2, thus enabling the pull of the pull rope 13. The guide wheel 14 steers the pull rope 13, allowing the pulling direction of the pull rope 13 to adapt to the driving direction of the driver 2.

[0032] Specifically, the linkage shaft 7 is located between the guide wheel 14 and the driver 2, and the pull rope 13 passes under the linkage shaft 7. A limiting groove (not shown in the figure) can be opened on the lower outer periphery of the linkage shaft 7, and a portion of the pull rope 13 can be embedded in the limiting groove to achieve position limiting of the pull rope 13.

[0033] In this embodiment, the driver 2 includes a driver end 21, and a pull cord 13 is connected to the driver end 21. The pull cord 13 enables linkage between the driver end 21 and the trigger 9, thereby automatically unlocking the locking element 4 and the locking element 5, thus enabling the dishwasher to open automatically.

[0034] Specifically, the drive end 21 has a reciprocating telescopic structure. The drive end 21 can be a reciprocating push rod or a wax motor mechanism capable of reciprocating telescopic movement. Alternatively, the drive end 21 can also have a rotating structure. The drive end 21 is equipped with a winding wheel, and the pull rope 13 is wound around the winding wheel of the drive end 21. Drive can also be achieved by winding and unwinding.

[0035] The dishwasher in this embodiment also includes an elastic element (not shown in the figure). The elastic element can elastically act on the locking element 5, elastically driving the locking element 5 to deflect in the locking direction, that is, causing the locking element 5 to elastically reset. Specifically, the elastic element is a torsion spring, installed at the rotation axis of the locking element 5, and can achieve an elastic action between the cabinet 1 and the locking element 5; or, the elastic element can also be a common compression spring or tension spring, which can achieve the elastic reset of the locking element 5.

[0036] Reference Figure 1 , Figure 2 As shown, locking member 4 has an upward hook, and locking member 5 has a downward hook. The hooks of locking member 4 and locking member 5 are adapted to each other to achieve mutual locking. Locking member 5 can be locked with locking member 4 by deflecting downward, and can be unlocked with locking member 4 by deflecting upward.

[0037] Linkage component 6 is a connecting rod, with its upper and lower ends respectively rotatably connected to linkage block 8 and locking component 2 5. When the linkage is activated, trigger component 9 swings downward, which can drive locking component 2 5 to deflect upward.

[0038] Furthermore, in this embodiment of the dishwasher, the door 3 includes a lower door 31 and an upper door 32, which are arranged vertically. The upper door 32 is rotatably connected to the cabinet 1 via an upper rotating member 11, and the lower door 31 is rotatably connected to the cabinet 1 via a lower rotating member 10. The upper door 32 is located above the lower door 31. The lower rotating member 10 and the upper rotating member 11 are linked to rotate through a linkage mechanism 12, thereby enabling the upper door 32 and the lower door 31 to open and close in a coordinated manner. When the upper door 32 and the lower door 31 are opened, their opening and closing actions need to be approximately synchronized.

[0039] Locking component 4 is installed on the lower door body 31, and the installation position of locking component 5 corresponds to that of locking component 4. By swinging the trigger 9 downward, locking component 5 can be driven to deflect upward, thereby enabling the lower door body 31 to be unlocked.

[0040] A magnetic adsorption structure is installed between the housing 1 and the upper door 32. Magnets and magnetic adsorption bodies are installed at corresponding positions on the housing 1 and the upper door 32, thereby enabling mutual magnetic adsorption.
