At this time, the door 10 is in an unlocked state with respect to the box 200, and the user pulls the door 10 to open the box 200. The condition that the user is scalded due to the fact that the door body 10 is opened by mistake can be better avoided through multi-step operation, particularly, a child can be better prevented from opening the door body 10 to be scalded in the cooking process, and the safety of the cooking appliance 1000 is greatly improved.

Referring to fig. 4-6, in some embodiments, the hook 22 includes a connection arm 221 and a clamping portion 222, the connection arm 221 is connected to the sliding portion 21, the clamping portion 222 is bent and extended from an end of the connection arm 221 away from the sliding portion 21 to form a barb structure 223, the clamping portion 222 is configured to be clamped on the position-limiting portion 201 when the sliding portion 21 is at the first position a, and the clamping portion 222 is configured to be separated from the position-limiting portion 201 when the sliding portion 21 is at the second position B.

Thus, the hook 22 can be engaged with the limiting portion 201 through the engaging portion 222 to lock the door 10 and the box 200, so as to prevent the user from directly pulling the door 10.

Specifically, the connection arm 221 extends from the sliding portion 21 toward the inner side of the door body 10, the engaging portion 222 is bent and extends from one end of the connection arm 221 opposite to the sliding portion 21, and the barb structure 223 can be located on the engaging portion 222. The sliding portion 21, the connecting arm 221 and the engaging portion 222 can be integrally formed by injection molding, so that the connection between the sliding portion 21 and the connecting arm can be firmer, and the restriction effect on the door body 10 is better. Of course, the connection may be realized in other manners, and the present application is not limited thereto.

The door body 10 can control the clamping fit between the clamping part 222 and the limiting part 201 by controlling the sliding part 21, so as to control the locking and unlocking of the door body 10 relative to the refrigerator body 200. When the door body 10 is closed relative to the box 200 and the sliding portion 21 is located at the first position a, the engaging portion 222 can be clamped on the limiting portion 201 to limit the door body 10 to be opened relative to the box 200, so that the door body 10 is in a locked state, and the door body 10 is prevented from being opened by mistake. When the sliding portion 21 is slid from the first position a to the second position B, the engaging portion 222 can be disengaged from the stopper portion 201, the door 10 is in an unlocked state, and the door 10 can be opened with respect to the box 200 by an external force.

Specifically, the included angle between the connection surface 2211 and the engagement surface 2221 can be understood as the bending degree of the engagement portion 222 relative to the connection arm 221, and the larger the bending degree of the engagement portion 222 relative to the connection portion is, the smaller the included angle between the connection surface 2211 and the engagement surface 2221 is, and the firmer the engagement between the stopper portion 201 and the engagement portion 222 is. When the door body 10 is pulled strongly, the position-limiting portion 201 is clamped in the included angle between the connection surface 2211 and the engaging surface 2221, and the position-limiting portion 201 does not slip along the engaging surface 2221 and the engaging portion 222.

The smaller the degree of bending of the engaging portion 222 with respect to the connecting portion, the larger the angle between the connecting surface 2211 and the engaging surface 2221. When the door 10 is pulled strongly, the position-limiting portion 201 follows the engaging surface 2221 and the slipping-off engaging portion 222, so that the door 10 is pulled away directly, and the safety is low.

Of course, in some other embodiments, the included angle between the engaging surface 2221 and the connecting surface 2211 may be a right angle, and the engaging portion 222 in the right angle state can also play a good role in holding. Preferably, the included angle between the engaging surface 2221 and the connecting surface 2211 is not an obtuse angle, and the door 10 can be easily pulled away directly by the engaging portion 222 in the obtuse angle state, which is likely to cause injury to the user.

Referring to fig. 4 to 6, in some embodiments, the sliding portion 21 can slide in the vertical direction relative to the door 10, and the first position a is located below the second position B. Thus, the sliding portion 21 can slide relative to the door body 10 more smoothly, so as to better drive the snap fit between the snap hook 22 and the limiting portion 201. Correspondingly, the limiting portion 201 can be inclined upward, and when the sliding portion 21 drives the hook 22 to slide downward, the limiting portion 201 can be better engaged with the hook 22.

In some embodiments, the number of the hooks 22 includes a plurality of hooks 22, the plurality of hooks 22 are arranged at intervals along the sliding direction of the sliding portion 21, and at least one hook 22 is provided with a barb structure 223.

So, a plurality of pothooks 22 interval sets up and can drive a plurality of pothooks 22 motion simultaneously when making to promote sliding part 21 on sliding part 21, and easy operation is convenient, and a plurality of pothooks 22 are held with corresponding spacing portion 201 card and are had better restriction effect to the door body 10, further avoid the door body 10 to be directly pulled open.
