LOCKING MEMBER FOR COOKING DEVICE, AND COOKING DEVICE

The present application relates to the field of electrical appliances, and more particularly, to a lock for a cooking appliance and a cooking appliance.

When the lid locking part in the cooking utensil becomes invalid, the main function is not affected, but it also has a certain effect on the use area.

For example, in some cooking appliances, for example, an electric pressure cooker, a locking mechanism is provided to prevent the lid of the cooker from being opened due to a user's malfunction when the pressure inside the pressure cooker is relatively high. The lid of the electric pressure cooker is provided with a locking port and a warming plate. In general, since the locking part and the heating plate are in surface contact, the locking part receives a relatively large resistance to the rotation process, which greatly affects the user's experience.

The present application provides a locking tool and a cooking appliance for cooking utensils, so that the locking member in the prior art is in surface contact with the heat insulating plate during the rotation process to solve the problem of relatively large resistance.

In order to solve the above technical problem, the present application provides a locking mechanism for cooking utensils, a ring-shaped frame; a locking portion formed on an outer periphery of the ring-shaped frame; a support part provided on one surface of the ring-shaped frame and positioned on the same side of the locking part and the ring-shaped frame; Among them, a height protruding from the ring-shaped frame of the locking portion is greater than a height protruding from the ring-shaped frame of the support portion.

Among them, a chamfer structure is provided on the surface facing the ring-shaped frame of the support.

Among them, the support includes a plurality of reinforcing ribs or a plurality of reinforcing columns.

Among them, a plurality of reinforcing ribs or a plurality of reinforcing pillars are provided distributed around the inner circumference of the ring-shaped frame.

Among them, the thickness of the reinforcing rib is 2mm to 5mm.

Among them, the locking portion includes a locking tooth and a locking hole, and a single locking tooth is spaced between the two adjacent locking holes; One end separated from the ring-shaped frame of the locking hole portion extends inward toward the ring-shaped frame to form a locking step.

Among them, the reinforcing rib is provided to correspond to the lock hole portion, and both ends of the reinforcing rib have the same length exceeding both ends of the lock hole portion.

Among them, the arc angle of the reinforcing rib exceeds the arc angle of the lock hole portion by 5° to 10°.

Among them, the ring-shaped frame is provided with a position fixture, and the reinforcing ribs corresponding to the locking holes on both sides of the position fixture are connected by one continuous reinforcing rib.

In order to solve the above technical problem, the present application is to provide a cooking utensil, the locking device of any one of the above is included.

The locking mechanism for cooking utensils of the present application includes a ring-shaped frame, a locking part and a support part, among which the support part and the locking part are provided on the same side of the ring-shaped frame, and the height protruding from the ring-shaped frame of the locking part is from the ring-shaped frame of the support part. Since it is larger than the protruding height, when the locking device comes into contact with the function plate, the ring-shaped frame is in contact with the function plate through the support, that is, the contact area between the locking member and the function plate is reduced, effectively reducing frictional resistance in the rotation process of the locking member. can be reduced In addition, the provision of the support can also improve the strength of the fastener, increase the service life of the fastener, and ensure the safety of use of the cookware.
