[0046] In the embodiment, the door lock device 100 comprises a door lock assembly 3, a door opening and closing mechanism 2 and a door lock actuating mechanism 1. The door lock assembly 3 comprises a lock seat 32 and a door lock piece 31, the door lock piece 31 is movably installed on the lock seat 32 and forms a locked state limited by the lock component 200 and an unlocked state disengaged from the lock component 200; the power output end of the door opening and closing mechanism 2 is in transmission connection with the lock seat 32 and drives the door lock assembly 3 to slide in the front and back directions; the power output end of the door lock actuating mechanism 1 is in transmission connection with the door lock piece 31 to drive the door lock piece 31 to switch between the locked state and the unlocked state.

[0047] The door lock device 100 provided in the embodiment can realize the cooperation of the door lock piece 31 and the lock component 200 in unlocking and locking by setting the door lock actuating mechanism 1 to actuate the door lock piece 31 to switch between the unlocked state and the locked state, so as to realize the automatic opening of the machine door 500 by driving the door lock piece 31 to the unlocked state, realize the automatic door opening operation, and keep the machine door 500 locked relative to the machine body when the door lock piece 31 is in the locked state; the door opening and closing mechanism 2 is set to drive the lock seat 32 to move in the front and back directions, so as to drive the door lock assembly 3 to move in the front and back directions as a whole when the door lock piece 31 is in the locked state, thereby driving the lock component 200 locked with the door lock piece 31 to move forward by the forward movement of the door lock assembly 3, and further realizing the automatic door opening action to make the machine door 500 open by a preset angle, meeting the demand of the appliance exhaust; meanwhile, the door opening and closing mechanism 2 drives the door lock assembly 3 to move backward when the machine door 500 is closed, which can effectively overcome the elastic force of the sealing strip between the machine door 500 and the machine body, realizing the tight closing of the machine door 500; furthermore, the setting of the door lock device 100 makes the user not need to force to overcome the elastic force of the door seal to close the machine door 500 in place when closing the door, but only need to close the machine door 500 to the locked state of the lock component 200 and the door lock piece 31, and then realize the tight closing of the machine door 500 by the door opening and closing mechanism 2 to pull the door lock assembly 3 backward, reducing the difficulty of closing the door and improving the use experience of the appliance.

[0048] When the machine door 500 is in the closed state, the hinge mechanism applies an elastic force to the machine door 500 to make the machine door 500 turn outward relative to the machine body, so that the machine door 500 can automatically turn outward under the action of the elastic force of the hinge mechanism when the door lock piece 31 is unlocked, realizing the automatic opening of the machine door 500, improving the convenience of opening the door of the appliance and the use convenience and experience of the appliance. In other embodiments, the machine door 500 can only be manually opened by the user. In other embodiments, the machine door 500 turns forward and opens under the action of the self weight after being opened by a certain angle.

[0049] Further, when the door 500 is flipped open to a preset angle relative to the machine body, the hinge mechanism provides damping to the door 500 to impede the flipping, so that the door 500 can be slowly turned downward under the joint action of the gravity and the resistance exerted by the hinge mechanism, avoiding the door 500 from being damaged due to the excessive speed of the downward flipping. The specific structure of the hinge mechanism can be set according to the prior art, which is not limited and described herein.

[0050] In the embodiment, the machine body includes an inner container 300 with an open front side and a machine case 400 surrounding the outer side of the inner container 300, the machine case 400 includes a front frame 402 surrounding the front side of the inner container 300, a top support plate 403 mounted above the inner container 300 and connected to the front frame 402 at the front end, and a machine shell 401 surrounding the outer side of the front frame 402 and the top support plate 403. The machine body further includes a control panel 600 mounted to the top front side of the front frame 402 through a panel support 601. The control panel 600, the top support plate 403, and the machine shell 401 surround a top cavity, and the control panel 600 extends forwardly out of the front side of the inner container 300.

[0051] The door lock actuating mechanism 1, the lock seat 32, and the automatic door opening and closing mechanism 2 are installed in the top cavity, and the part of the door lock piece 31 at least cooperating with the lock component 200 passes out of the top cavity through the panel support 601 and is located below the control panel 600 to improve the convenience of cooperation with the lock component 200.

[0052] As shown in FIGS. Figure 2 , Figure 4 and Figure 5 In the embodiment, the door lock piece 31 includes a lock shaft 311 arranged vertically and a lock hook 312 connected to the lower end of the lock shaft 311, the lock hook 312 has a lock groove 3121 for cooperating with the lock component 200, and the lock shaft 311 is rotatably installed in the lock seat 32. In other embodiments, the lock hook 312 itself can pass through the panel support 601, so that the rear end of the lock hook 312 is located in the top cavity and is rotatably connected with the lock seat 32, and the part of the lock hook 312 provided with the lock groove 3121 extends forwardly and downwardly out of the top cavity.

[0053] Further, the lock shaft 311 vertically passes through the lower side of the panel support 601, so that the upper end of the lock shaft 311 is located in the top cavity to facilitate the transmission connection with the door lock actuating mechanism 1, and the lower end of the lock shaft 311 extends out of the top cavity and is located at the front side of the inner container 300, and the lock hook 312 is connected to the lower end of the lock shaft 311. Preferably, the lock shaft 311 is arranged vertically.

[0054] In the embodiment, the electrical appliance is a cooking device with steam cooking function, and the condensation and heat dissipation assembly is arranged above the top support plate 403 and used for condensing and dissipating steam discharged from the inner container 300. The condensation and heat dissipation assembly includes a wind cover 700 and a heat dissipation fan 800. The wind cover 700 has an exhaust air duct in communication with the inner cavity of the inner container 300, and the heat dissipation fan 800 is used for guiding air flow into the exhaust air duct to dissipate steam. Further, the front end of the wind cover 700 has an air outlet in communication with the exhaust air duct. In other embodiments, the electrical appliance can also be a dishwasher, a sterilizer or other electrical appliance that needs to be vented at an angle.

[0055] The panel support 601 includes a front plate portion and four side plate portions surrounding four sides of the front plate portion. The side plate portion located at the lower side is a lower side plate 6011, which extends out of the front side of the wind cover 700 and is overlapped with the upper side of the front end of the wind cover 700 at the rear end. The lock seat 32 is slidably mounted on the lower side plate 6011 in the left-right direction, so that the lock shaft 311 is arranged at the front, and the lock shaft 311 penetrates out of the lower side plate 6011 at the lower side.

[0056] In the embodiment, the door opening and closing mechanism 2 is mounted at the rear side of the door lock assembly 3, and the door lock actuating mechanism 1 is mounted at one side of the door lock assembly 3 in the left-right direction. Therefore, the door lock actuating mechanism 1 and the door opening and closing mechanism 2 are dispersedly arranged, avoiding interference caused by structural concentration, and also avoiding heat accumulation caused by the concentration of the door lock actuating mechanism 1 and the door opening and closing mechanism 2. Further, the door opening and closing mechanism 2 is mounted at the upper side of the wind cover 700 and located at the rear side of the door lock assembly 3, so as to simplify the transmission connection structure between the door opening and closing mechanism 2 and the door lock assembly 3.

[0057] In the embodiment, the door lock actuating mechanism 1 includes an unlocking assembly and a door lock return member 13. The unlocking assembly actuates the door lock member 31 to rotate from the locked state to the unlocked state, and the elastic return member applies an elastic force to the door lock member 31 to keep or restore the door lock member 31 to the locked state. This arrangement allows the door lock member 31 to be automatically returned under the action of the door lock return member 13 when the door lock member 31 is in the unlocked state, thereby simplifying the structure of the door lock actuating mechanism 1, reducing the control difficulty of the door lock actuating mechanism 1, and facilitating the automatic door closing operation of the machine door 500.

[0058] It is worth noting that the lock hook 312 has a lock groove 3121. When the door lock assembly 3 is in the unlocked state, the slot of the lock groove 3121 faces forward, which can be directly forward or inclined forward, so that the lock member 200 can enter and exit the lock groove 3121 in the front-rear direction, thereby the machine door 500 can be opened relative to the machine body. When the door lock assembly 3 is in the locked state, the slot of the lock groove 3121 faces the left-right direction, so as to limit the lock member 200 from moving forward to escape from the lock groove 3121.

[0059] Furthermore, a guide surface is formed on the front side of the lock hook 312, which is located on the front side of the lock slot 3121 and extends forward from the notch of the lock slot 3121 in a direction away from the notch of the lock slot 3121. When the user closes the door and the lock hook 312 is in the locked position, the lock component 200 first contacts the guide surface. During the process of the user closing the door, the lock component 200 pushes the guide surface from front to back, causing the lock hook 312 to rotate in the direction toward the unlocked position, thereby guiding the lock component 200 into the lock slot 3121 of the lock hook 312, thereby realizing the user's manual door closing operation.

[0060] In this embodiment, the door lock assembly 3 is mounted in the middle of the machine body along the left-right direction, and the lock component 200 is mounted in the middle of the door 500 along the left-right direction, to improve the force balance of the door 500 when opening and closing. To improve the rationality of the layout of the door lock device 100 within the top cavity, in this embodiment, the unlocking assembly includes an unlocking drive assembly 11 and a transmission member 12. The unlocking drive assembly 11 is mounted on one side of the top cavity along the left-right direction, and the unlocking transmission assembly is arranged between the door lock drive member and the door lock member 31 and extends generally in the left-right direction. This prevents all structures of the door lock device 100 from being concentrated in the middle of the top cavity, which would cause interference between structures and heat accumulation. This improves the rationality of the layout of the door lock device 100 within the top cavity and enhances its reliability. Furthermore, the door lock device 100 also includes a drive seat 7, to which the unlocking drive assembly 11 is mounted.

[0061] The transmission member 12 is arranged in the left-right direction. The first end of the transmission member 12 is connected to or abuts the door lock member 31. The power output end of the unlocking drive assembly 11 acts on the second end of the transmission member 12, driving the transmission member 12 to move in the direction toward the door lock assembly 3, so that the transmission member 12 pushes the door lock member 31 from the locked state to the unlocked state. By hingedly connecting or abutting the first end of the transmission member 12 with the door lock member 31, the sliding of the door lock assembly 3 in the front-to-back direction does not affect the transmission of the door lock drive member to the door lock member 31, thereby improving the reliability of the door lock member 31 switching between the unlocked state and the locked state. At the same time, this arrangement allows the door lock assembly 3 to move in the front-to-back direction while the door lock drive member is stationary relative to the door body. This can reduce the driving load of the door opening and closing mechanism 2, thereby reducing the size of the door opening and closing drive mechanism, reducing the operating cost of the door lock device 100, and facilitating the structural arrangement.

[0062] In other embodiments, the unlocking assembly can be mounted on the lock base 32. That is, when the door opening and closing mechanism 2 drives the door lock assembly 3 in the forward and backward direction, the unlocking assembly moves along with the door lock assembly 3. It is understood that in this arrangement, the unlocking assembly can include a drive motor, the output shaft of which is coaxially arranged with the lock shaft 311, and the drive motor drives the lock shaft 311 to rotate; or the unlocking assembly can include a drive motor, and the drive motor drives the lock shaft 311 to rotate via a gear transmission structure, a worm gear 222 and a worm 221 transmission structure, etc. The present invention does not limit the specific structure of the door lock actuating mechanism 1.

[0063] In this embodiment, the unlocking drive assembly 11 includes an unlocking drive motor 111 and a cam 112. The unlocking drive motor 111 has an output shaft that can rotate around itself. The output shaft is connected to the cam 112 to drive the cam 112 to rotate, thereby pushing the unlocking transmission member 12 to move in the left and right directions. In other embodiments, the unlocking drive assembly 11 can also adopt other structures that can achieve left and right movement of the transmission member 12, such as a drive motor and connecting rod 122 structure, a drive motor and rack and pinion structure, etc.

[0064] Furthermore, to facilitate the connection between the door lock member 31 and the door lock actuating mechanism 1, a driven member 313 is connected to the upper end of the lock shaft 311. The first end of the transmission member 12 is hingedly connected to or abuts against the driven member 313 via the hinge shaft 34. The position where the transmission member 12 acts on the driven member 313 is spaced apart from the axis of the lock shaft 311 in the front-to-back direction. As a result, when the transmission member 12 moves toward the door lock member 31, the transmission member 12 pushes the driven member 313 to rotate about the axis of the lock shaft 311, thereby causing the door lock member 31 to rotate about the axis of the lock shaft 311.

[0065] In an embodiment, the transmission member 12 includes a slide 121 and a connecting rod 122. The slide 121 can be slidably installed on the driving seat 7 in the left and right directions.

In other embodiments, the connecting piece 23 and the lock seat 32 can also be connected through screws or other detachable connection structures.

[0077] In the embodiment, the plug-in protrusion 232 is arranged in the vertical direction, which is beneficial to simplify the matching structure between the lock seat 32 and the connecting piece 23. In other embodiments, the plug-in protrusion 232 can also extend in the left-right direction. In the embodiment, the plug-in protrusion 232 is arranged on the connecting piece 23, so as to simplify the structure of the lock seat 32. Specifically, the connecting piece 23 includes an adapter seat portion 231, the adapter seat portion 231 is connected with the power output end, and the plug-in protrusion 232 is protruded from the adapter seat portion 231.

[0078] Further, the adapter seat portion 231 includes a vertical plate portion 2311 and a horizontal plate portion 2312 which are connected vertically, the vertical plate portion 2311 is arranged vertically and connected with the power output end, the horizontal plate portion 2312 is connected with the lower end of the vertical plate portion 2311 and extends in the direction towards the door lock assembly 3; the lower side of the horizontal plate portion 2312 is protruded and provided with the plug-in protrusion 232. Thus, the connection convenience of the connecting piece 23 and the power output end can be improved, the structure of the connecting piece 23 is simplified, and the overall structural strength and rigidity of the connecting piece 23 are enhanced.

[0079] The upper end of the lock seat 32 is provided with a groove, and the horizontal plate portion 2312 is arranged in the groove, so as to avoid the horizontal plate portion 2312 protruding from the lock seat 32 and interfering with the transmission member 12.

[0080] In this embodiment, both the front and rear sides of the lock base 32 are slidably engaged with the mounting base 4, thereby increasing the sliding engagement length between the mounting base 4 and the lock base 32, thereby improving the reliability of the door lock assembly 3 in the forward and backward sliding direction. A clearance hole 41 is defined on the rear side of the mounting base 4, into which the insertion protrusion 232 can be movably inserted in the forward and backward direction, thereby preventing the arrangement of the mounting base 4 from interfering with the engagement protrusion 232 and the lock base 32.

[0081] Furthermore, a detachable anti-slip component 233 is provided on the plug-in protrusion 232, and the portion of the lock base 32 where the plug-in hole 3221 is formed is sandwiched between the anti-slip component 233 and the adapter base 231. This ensures that the lock base 32 and the connector 23 are completely restrained in the extending direction of the plug-in protrusion 232, further improving the connection reliability between the lock base 32 and the connector 23, thereby ensuring the reliability of the door lock assembly 3 driven by the door opening and closing mechanism 2.

[0082] In this embodiment, the anti-slip component 233 abuts the lower side of the mounting base 4, so that the rear side of the mounting base 4 and the rear side of the lock base 32 are both sandwiched between the horizontal plate portion 2312 and the anti-slip component 233. Preferably, the lower outer wall of the plug-in protrusion 232 is provided with an external thread, and the anti-slip component 233 is screwed onto the plug-in protrusion 232 to improve the ease of assembly and disassembly of the anti-slip component 233 on the plug-in protrusion 232 and improve the stability of the installation after the installation.

The translation drive motor 21 is mounted on a mounting base 24. The worm 221 extends in the front-to-back direction and is slidably mounted on the mounting base 24 in the front-to-back direction. The front end of the worm 221 is connected to the connector 23. This transmission structure of the worm gear 222 and worm 221 achieves forward and backward drive of the connector 23, resulting in a simple structure, a small footprint, and facilitates self-locking, thereby facilitating the door lock assembly 3 to stably maintain a desired position in the front-to-back direction, thereby improving the reliability of the door lock device 100.

[0084] In other embodiments, the translation drive assembly may also utilize the translation drive motor 21 in conjunction with other structures to achieve movement of the connector 23 in the left-right direction, such as a rack and pinion transmission structure.

[0085] The mounting seat 24 has a mounting groove, the worm wheel 222 is located in the mounting groove, and the two ends of the worm 221 slide through the front and rear groove walls of the mounting groove. The worm wheel 222 is arranged in the mounting groove, thereby facilitating protection of the worm wheel 222 and the worm 221. At the same time, the two ends of the worm 221 slide through the front and rear groove walls arranged in the mounting groove, thereby facilitating guiding of the movement of the worm 221 in the front and rear directions and avoiding the need to additionally arrange other guiding structures.

[0086] Further, the upper end of the mounting seat 24 is open to form an upper groove opening of the mounting groove. The bottom of the mounting groove is protrusively provided with a mounting protrusion 243. The translation driving motor 21 is mounted on the mounting protrusion 243, thereby facilitating disassembly and assembly of the translation driving assembly on the mounting seat 24 and facilitating heat dissipation of the translation driving motor 21. The motor shaft of the translation driving motor 21 extends downward out of the motor shell 401 and is connected to the worm wheel 222, thereby improving the installation convenience of the translation driving motor 21 and reducing the interference between structures. In other embodiments, the mounting seat 24 can include a seat body and an upper cover. The upper cover is arranged on the upper end of the seat body. The seat body and the upper cover jointly form the mounting groove.

[0087] The mounting protrusion 243 is arranged at intervals along the circumferential direction of the worm wheel 222. The motor shell 401 of the translation driving motor 21 outwardly extends a fixing lug 211. The fixing lug 211 is arranged in one-to-one correspondence with the mounting protrusion 243. The fixing lug 211 is detachably connected to the mounting protrusion 243, thereby achieving mounting of the translation driving motor 21 on the mounting seat 24. Preferably, one mounting protrusion 243 is arranged on each of the front and rear sides of the worm wheel 222, thereby simplifying the structure of the mounting seat 24 and ensuring the mounting stability and reliability of the translation driving motor 21.

[0088] To improve the installation convenience of the worm 221, at least one side of the mounting groove is open to form a side groove opening. One of the front and rear groove walls of the mounting groove is provided with a circular limiting rod hole 2411. The other is provided with a mounting rod hole 2412. The mounting rod hole 2412 extends along the left and right directions and is in communication with the side groove opening at one end. The two ends of the worm 221 are respectively arranged in the limiting rod hole 2411 and the mounting rod hole 2412. By arranging the side groove opening, the middle part of the worm 221 can be slid into the mounting groove through the side groove opening and the mounting rod hole 2412 when the worm 221 is installed. After the worm 221 is moved to the left and right directions to be opposite to the limiting rod hole 2411, the worm 221 is moved in the front and rear directions to insert the corresponding end of the worm 221 into the limiting rod hole 2411, thereby achieving mounting of the worm 221 on the mounting seat 24.

[0089] Specifically, the mounting seat 24 comprises a seat bottom plate part 241, the front and rear sides of the seat bottom plate part 241 are vertically connected with mounting side plate parts 242, and the seat bottom plate part 241 and the mounting side plate parts 242 jointly form a mounting groove. One of the mounting side plate parts 242 is provided with the limiting rod hole 2411, and the other mounting side plate part 242 is provided with the mounting rod hole 2412. The first ends of the two mounting side plate parts 242 form the side notch. Further, the seat bottom plate part 241 is provided with a mounting protrusion 243.

[0090] Further, the mounting seat 24 further comprises a baffle part 244 connected between the two mounting side plate parts 242, the baffle part 244 is arranged opposite to the side notch, and the baffle part 244 is arranged away from the baffle part 244, the baffle part 244 is used to avoid the relative shaking of the two mounting side plate parts 242, and the overall structural strength and rigidity of the mounting seat 24 is improved. The upper end of the baffle part 244 is higher than the worm 221, so as to facilitate the shielding protection of the worm 221. Further, the mounting seat 24 further comprises a reinforcing edge part 245 connected between the first ends of the two mounting side plates, and the reinforcing edge part 245 is arranged lower than the limiting rod hole 2411 and the mounting rod hole 2412.

[0091] In order to further improve the mounting stability of the worm 221 on the mounting seat 24, in the embodiment, the worm 221 comprises a threaded rod part and a light rod part coaxially connected to both ends of the threaded rod part, and the light rod parts at both ends are respectively slid through the limiting rod hole 2411 and the mounting rod hole 2412. The end of each light rod part away from the threaded rod part is coaxially connected with a limiting rod part, and the outer diameter of the limiting rod part is smaller than the outer diameter of the light rod part, so that a positioning step surface is formed between the limiting rod part and the light rod part. A anti-dropping piece 26 is detachably arranged on each limiting rod part, and the anti-dropping piece 26 is limited to pass through the corresponding limiting rod hole 2411 or the mounting rod hole 2412.

[0092] Preferably, the limiting rod part is a screw structure, and the anti-dropping piece 26 is a nut screwed on the screw structure, so as to improve the mounting stability and reliability of the anti-dropping piece 26. Further, the connecting piece 23 is sleeved on the limiting rod part and clamped between the anti-dropping piece 26 and the step surface.

[0093] The switch door mechanism 2 has an extension limiting structure and a retraction limiting structure, the extension limiting structure limits the maximum stroke of the worm 221 extending forward, and the retraction limiting structure limits the maximum stroke of the worm 221 retracting backward. By arranging the extension limiting structure and the retraction limiting structure, the forward and backward movement of the worm 221 can be limited, so that the movement of the door lock assembly 3 is limited, avoiding that the door lock assembly 3 moves too far forward to knock the operation panel 600, and also avoiding that the door lock assembly 3 moves too far backward to cause the door 500 to excessively press the door seal on the front side of the machine body, thereby improving the use reliability of the door lock assembly 3 and the door lock device 100.

[0094] In the embodiment, the protruding limiting structure comprises a limiting protrusion 2211 protruding from the worm 221, and the limiting protrusion 2211 is capable of abutting against the front slot wall of the mounting slot. By protruding the limiting protrusion 2211 from the worm 221 to limit the forward movement of the worm 221, the structure of the worm 221 is simplified, and the machining difficulty of the worm 221 is reduced. The limiting protrusion 2211 is protruded from the light rod part, and is preferably in a ring structure. In other embodiments, the limiting of the forward movement of the worm 221 can also be achieved by the abutment between the second nut and the rear side of the mounting seat 24.

[0095] Further, the front slot wall of the mounting seat 24 cooperates with the connecting piece 23 to form a retraction limiting structure, that is, when the connecting piece 23 abuts against the front side of the mounting seat 24, the worm 221 reaches the maximum stroke of the backward movement, thereby avoiding the additional setting of other limiting structures and simplifying the overall structure of the door opening and closing mechanism 2.
