[0056] The reset part 250 is elastically connected between the locking part 230 and the first hinge part 210, and is used to drive the locking part 230 to remain at the first position.

[0057] ​The reset member 250 is elastically connected between the locking portion 230 and the first hinge portion 210 to apply an elastic force to the locking portion 230, so that the locking portion 230 is kept in the first position. When the human hand is away from the operation portion 240, the locking portion 230 is driven by the reset member 250 to return to the first position, and when the door body 110 is closed, the locking portion 230 can be locked with the second hinge portion 220 to fix the door body 110.

[0058] It should be noted that the door lock device 200 of the present application can be a safety lock of the cooking appliance, that is, the above-mentioned locking portion 230 is the first lock of the cooking appliance, and the user cannot remove the first lock by directly pulling the door. The cooking appliance itself has a resilient door lock, which is the second lock of the cooking appliance, and the user can use a small force to pull the door handle outward to remove the resilient door lock.

[0059] In actual execution, the locking portion 230 is kept in the first position by the elastic force of the reset member 250, and the locking portion 230 is locked with the second hinge portion 220, so that the door body 110 cannot be opened. When opening the door, the operation portion 240 needs to be manually controlled first to drive the locking portion 230 to slide to the second position, so that the locking portion 230 is in an unlocked state with the second hinge portion 220, and the first unlocking is completed. Then, the door body 110 is pulled to separate the door body 110 from the main machine 120 to realize the second unlocking. After the two unlocking operations, the door body 110 is opened. When closing the door, the door body 110 is closed on the main machine 120, the locking portion 230 is restored to the first position under the action of the reset member 250, and is locked with the second hinge portion 220, so that the door body 110 cannot be opened, and the closing of the door body 110 is completed.

[0060] According to the door lock device 200 provided by the embodiments of the present application, the locking portion 230 is locked with the second hinge portion 220, when opening the door, the operation portion 240 needs to be controlled first to drive the locking portion 230 to be unlocked with the second hinge portion 220, then the door body 110 is pulled to realize the second unlocking, so that the door body 110 can be completely opened. This can prevent children from being scalded or putting dangerous objects into the cooking appliance by mistake, improve the safety of the cooking appliance, and the unlocking operation is simple.

[0061] As shown in FIG. 1, Figures 1-4 According to some embodiments of the present application, the first hinge portion 210 can include a hinge seat 211 and a mounting bracket 213.

[0062] As shown in FIG. 1, Figures 1-4 The hinge seat 211 can be used to be connected with the main machine 120 or the door body 110.

[0063] The hinge seat 211 can be mounted on the main body 120 or on the door body 110, the hinge groove 212 is arranged on the hinge seat 211, and the sliding block 221 of the second hinge part 220 is in sliding fit with the hinge groove 212 of the hinge seat 211. The activity stroke of the second hinge part 220 is guided and limited by the hinge seat 211, so that the cooperation of the first hinge part 210 and the second hinge part 220 is more stable.

[0064] As shown in Figures 1-3 , the mounting bracket 213 can be mounted on the hinge seat 211, and the locking part 230 can be slidingly mounted on the mounting bracket 213.

[0065] The mounting bracket 213 can be connected with the hinge seat 211 by screw connection, or can be connected with the hinge seat 211 by buckle connection or adhesive connection, etc., which is not limited here. The locking part 230 can be slidingly mounted on the mounting bracket 213, and the mounting bracket 213 plays a guiding and limiting role for the locking part 230, facilitating the movement of the locking part 230. At the same time, because the mounting bracket 213 is mounted on the mounting seat, the locking part 230 can be limited with the second hinge part 220.

[0066] By setting the mounting bracket 213, the mounting bracket 213 is mounted on the original hinge structure, and the mounting bracket 213 and the hinge seat 211 cooperate to form the first hinge part 210 and the second hinge part 220, so that the door lock device 200 can be retrofitted to add the mounting bracket 213 and the locking part 230 to realize the increase of the child safety lock on the basis of the original, which is simple to modify and saves production cost.

[0067] As shown in Figures 1-3 , according to some embodiments of the present application, one of the locking part 230 and the mounting bracket 213 can be provided with a guide column 214, and the other can be provided with a guide groove 232 matched with the guide column 214.

[0068] The guide column 214 penetrates the guide groove 232 and is arranged, and the guide column 214 and the guide groove 232 are matched with each other to guide the movement direction of the locking part 230 on the mounting bracket 213, which can prevent the locking part 230 from deviating from the position. With the sliding of the locking part 230 on the mounting bracket 213, the guide column 214 can be slidingly arranged in the extension direction of the guide column 214 in the guide groove 232. Among them, the guide column 214 extends in the direction close to and away from the mounting bracket 213, so that the locking part 230 can slide in the direction close to and away from the mounting bracket 213.

[0069] As shown in Figures 1-3 , in this embodiment, the guide column 214 can be arranged on the mounting bracket 213, and the locking part 230 is provided with the guide groove 232 matched with the guide column 214.

[0070] In another embodiment, the guide post 214 can be disposed on the locking portion 230, and the mounting bracket 213 is provided with a guide groove 232 that mates with the guide post 214. Here, since the guide post 214 can slide within the guide groove 232, in order to avoid interference between the guide post 214 and the hinge seat 211, in one example, a through hole can also be provided on the hinge seat 211, through which the guide post 214 can pass through the guide groove 232 and the through hole to facilitate the movement of the locking portion 230.

[0071] According to some embodiments of this application, the reset member 250 can be sleeved on the guide post 214 and can be elastically abutted between the locking part 230 and the mounting bracket 213.

[0072] The reset element 250 is sleeved outside the guide post 214. The reset element 250 can be a spring or an elastic ring. By sleeved outside the guide post 214, the guide post 214 limits the reset element 250 and prevents it from deviating. The reset element 250 elastically abuts between the locking part 230 and the mounting bracket 213. The reset element 250 can always apply an elastic force away from the mounting bracket 213 to the locking part 230. The locking part 230 is always kept in the first position by the elastic force of the reset element 250. When the locking part 230 moves to the position furthest from the mounting bracket 213, the locking part 230 can be locked and limited by the second hinge part 220.

[0073] In actual operation, the control unit 240 drives the locking part 230 to overcome the elastic force of the reset member 250 and move it in the direction close to the mounting bracket 213 until the locking part 230 moves to the second position. At this time, the locking part 230 separates from the second hinge part 220 or does not interfere with the movement of the second hinge part 220, and the door lock device 200 unlocks. After the control unit 240 is released, the reset member 250 releases its elastic potential energy and drives the locking part 230 to move in the direction away from the mounting bracket 213 until the locking part 230 moves to the first position. At this time, the locking part 230 locks with the second hinge part 220 or interferes with the movement of the second hinge part 220, the door lock device 200 locks, and the door 110 cannot be opened.

[0074] like Figures 1-3 As shown, in some embodiments, one end of the guide post 214 may be provided with a screw washer assembly 270, which includes a screw 271 and a washer 272.

[0075] The screw 271 is threadedly connected with the guide column 214, and the gasket 272 is arranged between the screw 271 and the guide column 214, and the cross-sectional size of the gasket 272 is greater than the cross-sectional size of the guide groove 232, so that the gasket 272 can play a role of clamping and limiting, preventing the guide column 214 from being separated from the guide groove 232 and the clamping portion 230 from falling due to the action of the reset member 250.

[0076] When the guide column 214 is arranged on the mounting bracket 213, the end of the guide column 214 away from the mounting bracket 213 is provided with a screw gasket assembly 270 for abutting and limiting the side of the clamping portion 230 away from the mounting bracket 213.

[0077] When the guide column 214 is arranged on the clamping portion 230, the end of the guide column 214 away from the clamping portion 230 is provided with a screw gasket assembly 270 for abutting and limiting the side of the mounting bracket 213 away from the clamping portion 230.
