In this embodiment, an excessive displacement S2 of the second locking portion 31 from the first position to the second position affects the return stroke of the second locking portion 31, and an excessively small displacement S2 of the second locking portion 31 from the first position to the second position causes the first locking portion 30 and the second locking portion 31 to easily interfere with each other, so that the displacement S2 of the second locking portion 31 from the first position to the second position is set before 2mm to 15mm, both of the stroke of the second locking portion 31 from the second position to the first position is shortened, and interference between the first locking portion 30 and the second locking portion 31 can be avoided in the case of unlocking.

In a specific application, the displacement S2 of the second locking portion 31 from the first position to the second position is equal to any value of 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14 mm.

As shown in fig. 3, according to an embodiment of the present invention, on the basis of the above embodiment, further, the door body 2 includes: the door body 20 and the door surface 22 are oppositely arranged, the door body 20 and the door surface 22 surround the accommodating space 26, the door body 20 is close to the cooking main body 1, one part of the second locking part 31 is arranged in the accommodating space 26, and the other part extends out of the door body 20.

In this embodiment, the door body 2 includes a door body 20 and a door surface 22, the door body 20 is disposed on one side of the door surface 22 near the cooking main body 1, the door body 20 and the door surface 22 are disposed opposite to each other and enclose the accommodating space 26, and a part of the structure of the child lock assembly 3 is disposed in the accommodating space 26, so that the child lock assembly 3 is prevented from being exposed, and the aesthetic property of the cooking appliance is improved. Wherein, a part of the second locking portion 31 is disposed in the accommodating space 26, and another part is extended from the door body 20 to be engaged with the first locking portion 30.

In a particular application, the door facing 22 is provided with a handle. Further, the second locking portion 31 is connected to the door body 20.

Further, the door body 2 further includes a door seal 24, and the door seal 24 is disposed at a side of the door body 20 facing the cooking main body 1.

As shown in fig. 1, according to an embodiment of the present invention, further, the child lock assembly 3 is disposed near a side or top of the door body 2 on the basis of the above embodiment.

In this embodiment, the child lock assembly 3 is located near the side or top of the door body 2 such that the child lock assembly 3 is located away from the handle of the door body 2, thereby improving the safety of the two-step operation.

In particular applications, cooking appliances include microwave ovens, steamers, steam-roast bins, and the like.

In a specific application, the cooking appliance comprises a cooking main body 1 and a door body 2, wherein the door body 2 is a door assembly, and a child lock assembly 3 is mainly installed in the door assembly to realize a child lock function with mechanical delay.

As shown in fig. 5, 6 and 7, the child lock assembly 3 includes a door hook (i.e., the second locking portion 31), a bracket 300 (i.e., the first locking portion 30), a mounting member 35, a spring, a key 32, a damping member 34 and a pressing plate 36. The bracket 300 is fixed at the front end of the cooking body 1, and the door hook comprises a first lock catch 314, a movable part 312, a bevel structure 3120 and a spring hook (a second limit part 310), and is assembled on the guide rail 350 and can slide up and down along the guide rail 350; the damping piece 34 comprises an air cylinder 340 and a sliding rod 342, the sliding rod 342 can slide up and down along the air cylinder 340, and the sliding rod 342 has small resistance when extending out and large resistance when retracting in, thus playing a damping role; further, the damper 34 is fitted on one end of the guide rail 350, and the pressing plate 36 presses the damper 34, and is fastened by a button or screw fitting, so that the guide rail 350, the damper 34, and the pressing plate 36 are fastened together. Further, the sliding rod 342 is fixed (sleeved) at one end of the door hook, and when the door hook slides along the guide rail 350, the sliding rod 342 is driven to slide together. One end of a spring (tension spring) is hung on a spring hook (a second limiting part 310) on the door hook, the other end of the spring (tension spring) is hung on a spring hook (a first limiting part 352) on the guide rail 350, the key 32 is assembled on the door surface 22, and the key 32 can slide in or slide out in a hole (a revolving body) of the key 32 of the door surface 22. In a normal state (when the oven door is normally closed), the door hook is pulled by the spring, and slides to one end of the guide rail 350 and drives the sliding rod 342 to retract, the first lock catch 314 tightly catches the second lock catch 302, at this time, the door hook pulls the bracket 300, and the oven door component cannot be opened, so that the child lock function is realized. When the door is to be opened, the key 32 is pressed down, so that the key 32 slides inwards to the bottom in the key 32 hole of the door surface 22, the front end rod of the key 32 is pressed onto the inclined surface structure 3120 of the door hook, so that the door hook moves along the guide rail 350, the first lock catch 314 synchronously moves away from the second lock catch 302, and simultaneously, the door hook synchronously drives the spring to stretch (the tension of the spring becomes larger) and drives the slide bar 342 to stretch, and the first lock catch 314 moves away from the second lock catch 302, so that the key 32 can be released, the handle of the door assembly is pulled, and the door is opened, thereby playing a role of two-step door opening. When the key 32 is released, the spring force of the spring pulls the door hook to move backwards, the door hook synchronously drives the sliding rod 342 to retract, further, the pulling force of the spring is always larger than the resistance of the sliding rod 342, the door hook slowly moves under the damping force of the sliding rod 342 to return to the original position, and the first lock catch 314 is buckled with the second lock catch 302 again, so that delayed self-locking is realized.

Further, the movement direction of the key 32 is not parallel (perpendicular or forms an included angle) with the direction of the door hook, for example, the front-back movement of the key 32 is converted into the up-down or left-right movement of the door hook, so as to realize the actions of locking and unlocking the door.

Further, as shown in fig. 4, the movement stroke S1 of the key 32 is between 2mm and 15mm.

Further, as shown in FIG. 5, the angle B of the ramp structure 3120 is between 25-75.

Further, as shown in fig. 5, the movement stroke S2 of the door hook is between 2mm and 15mm.

Further, the main body portion of the child lock assembly 3 is installed between the door body 20 and the door surface 22, and only the door hook protrudes from the side of the door body 20 by the first locker 314, so that the structural size of the door assembly is minimized.

Further, the child lock assembly 3 may be mounted on the left, right or upper side of the door assembly. And the child lock assembly 3 can be installed after being rotated by any angle. The structure can be applied to the edge of the furnace door assembly and a position far away from the handle, so that the safety performance of two-step operation is improved. Further, the keys 32 may be mounted on the top or side of the door facing 22.

According to the cooking appliance, the pressing motion of the key 32 is converted into the motion of the door hook in different directions on different planes, so that the actions of locking and unlocking are realized, and the two-step door opening is realized; the sliding rod 342 of the damping piece 34 is fixed on the door hook, so that the door hook slowly moves during return stroke, delayed self-locking is realized, the convenient effect of opening the door by one hand is achieved, and compared with the electronic child lock in the related art, the mechanical key 32 provided by the application is simple and easy to use.

Further, the sliding direction between the second locking portion 31 and the guide rail 350 may be set in any direction, so as to achieve multi-directional unlocking and limiting.
