Especially after children cook food using the cooking appliance, accidents are more likely to occur.

Disclosure of Invention

The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

In view of this, the present invention proposes a lock structure comprising: a key assembly movable in a first direction; the limiting piece is arranged on the substrate to be installed and is positioned on the moving path of the key assembly; the operating piece is arranged on the key assembly along a first direction, the operating piece and the limiting piece are arranged on two sides of the key assembly, the operating piece is used for pushing the key assembly, the operating piece can reciprocate along a second direction relative to the key assembly, and the first direction and the second direction are different directions; when the operating piece moves to the first position along the second direction, the limiting piece limits the operating piece to push the key assembly, and when the operating piece is positioned at the second position, the limiting piece releases the limitation on the operating piece.

The lock structure provided by the invention is used for a cooking appliance, the cooking appliance comprises a door body and a cavity assembly, and the operating piece, the key assembly and the limiting piece are used as child locks to play a role in auxiliary connection of the door body and the cavity assembly.

The cooking utensil is provided with interlocking subassembly and hasp generally, and interlocking subassembly can drive the lock position separation on hasp and the cavity subassembly, when not setting up child lock structure on the cavity subassembly, the user just can open the cavity subassembly to the pulling of door body. Through increasing child lock structure on cavity subassembly, the user can press the operating piece, then the operating piece drives button subassembly and removes, and when button subassembly pushed the interlocking subassembly, the interlocking subassembly can drive the hasp motion. When the door body closes the cooking cavity, the lock catch is connected with the cavity component. When the operating member is located at the first position, the limiting member limits the operating member to move along the first direction, and at the moment, the operating member cannot push the key assembly. Before the cavity assembly is opened, the operation member needs to be pushed to move, when the operation member moves to the second position, the limiting member avoids the operation member, and at the moment, a user can press the operation member and drive the key assembly to move. The opening of the cavity assembly requires two steps of operation, which is beneficial to improving the use safety of the cooking utensil.

Specifically, when the door body closes the cavity component, the lock catch is buckled with the buckling phase on the cavity component, so that the condition that the door body opens the cavity component under the condition that no external force exists is avoided. After the button assembly pushes the interlocking assembly, the interlocking assembly pushes the lock catch to move relative to the buckling position on the cavity assembly, so that the lock catch is separated from the buckling position, and the cavity assembly can be opened. According to the invention, the child lock structure is added on the cooking utensil, when the operating piece moves to the first position, the limiting piece limits the operating piece to push the key assembly, and the lock catch is difficult to separate from the buckling position on the cavity assembly, so that the door body is kept in a locking state, and therefore, the cavity assembly cannot be opened.

When the key assembly faces to or is far away from the interlocking assembly, the key assembly moves back and forth along the first direction, so that in order to push the key assembly, a user needs to push the operating member to move along the first direction, and the operating member pushes the key assembly along the first direction. The operating member is slidably connected to the key assembly, so that the operating member needs to be moved to a position away from the stopper in order to be able to push the key assembly through the operating member. Therefore, the user needs to push the operation member to move to the second position along the second direction, which is the first step operation, and then push the operation member to move along the second direction and push the key assembly, which is the second step operation. Through two steps of operation, the difficulty of opening the door is increased.

After the cooking utensil finishes the cooking process, the temperature of food in the cooking cavity is higher, and the user directly opens the door body and takes out food and have the risk of scalding this moment. Therefore, the child lock structure enables a user to open the cavity assembly, and two-step door opening operations are required to be performed before the cavity assembly is opened. Therefore, on one hand, a certain prompting effect can be achieved for a user, on the other hand, the situation that a child opens the cavity assembly by mistake can be prevented, and the use safety of the cooking utensil is greatly improved.

Detailed Description

In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

A lock structure and a cooking appliance provided according to some embodiments of the present application are described below with reference to fig. 1 to 10.

As shown in connection with fig. 1, 2 and 3, in some embodiments of the present application, a lock structure is proposed, comprising: the key assembly 500, the limiting member 600 and the operating member 700, the key assembly 500 being movable in a first direction; the limiting piece 600 is arranged on the substrate to be installed, and the limiting piece 600 is positioned on the moving path of the key assembly 500; the operation piece 700 is arranged on the key assembly 500, the operation piece 700 and the limiting piece 600 are positioned on two sides of the key assembly 500 along a first direction, the operation piece 700 is used for pushing the key assembly 500, the operation piece 700 can reciprocate along a second direction relative to the key assembly 500, and the first direction and the second direction are different directions; when the operation member 700 moves to the first position along the second direction, the limiting member 600 limits the operation member 700 to push the key assembly 500, and when the operation member 700 is located at the second position, the limiting member 600 releases the limitation on the operation member 700.

The cooking appliance provided in this embodiment is used for a cooking appliance, and the cooking appliance includes a door body 200 and a cavity assembly 100, and an operating member 700, a key assembly 500 and a limiting member 600 serve as a child lock and serve as an auxiliary connection door body 200 and cavity assembly 100.

The cooking appliance is generally provided with an interlocking assembly 400 and a lock catch 300, wherein the interlocking assembly 400 can drive the lock catch 300 to be separated from a buckling position on the cavity assembly 100, and when the cavity assembly 100 is not provided with a child lock structure, a user pulls the door body 200 to open the cavity assembly 100. By adding the child lock structure to the cavity assembly 100, a user can press the operation member 700, and then the operation member 700 drives the key assembly 500 to move, and when the key assembly 500 pushes the interlock assembly 400, the interlock assembly 400 can drive the lock catch 300 to move. When the door 200 closes the cooking cavity, the latch 300 is connected with the cavity assembly 100. When the operation member 700 is located at the first position, the limiting member 600 limits the movement of the operation member 700 in the first direction, and the operation member 700 cannot push the key assembly 500. Before opening the cavity assembly 100, the operation member 700 needs to be pushed to move, and when the operation member 700 moves to the second position, the limiting member 600 dodges the operation member 700, and at this time, the user can press the operation member 700 and drive the key assembly 500 to move. Opening the cavity assembly 100 requires a two-step operation, which is advantageous for improving the use safety of the cooking appliance.

Specifically, when the door 200 closes the cavity assembly 100, the lock catch 300 is engaged with the engagement phase on the cavity assembly 100, so as to avoid the situation that the door 200 opens the cavity assembly 100 without external force. After the key assembly 500 pushes the interlocking assembly 400, the interlocking assembly 400 pushes the lock catch 300 to move relative to the buckling position on the cavity assembly 100, so that the lock catch 300 is separated from the buckling position, and the cavity assembly 100 can be opened. In the invention, a child lock structure is added on the cooking appliance, when the operation member 700 moves to the first position, the limiting member 600 limits the operation member 700 to push the key assembly 500, and the lock catch 300 is difficult to separate from the buckling position on the cavity assembly 100, so that the door 200 is kept in a locked state, and therefore, the cavity assembly 100 cannot be opened.

When the key assembly 500 moves toward or away from the interlock assembly 400, the key assembly 500 moves back and forth along the first direction, so that in order to push the key assembly 500, the user needs to push the operation member 700 to move along the first direction, so that the operation member 700 pushes the key assembly 500 along the first direction. The operation member 700 is slidably coupled to the key assembly 500, so that the operation member 700 needs to be moved to a position away from the stopper 600 in order to be able to push the key assembly 500 through the operation member 700. Therefore, the user needs to push the operation member 700 in the second direction to move to the second position, which is the first step operation, and then push the operation member 700 to move in the second direction and push the key assembly 500, which is the second step operation. Through two steps of operation, the difficulty of opening the door is increased.

After the cooking process of the cooking appliance is finished, the temperature of the food in the cooking cavity is high, and at this time, the user directly opens the door body 200 to take out the food, so that the risk of scalding exists. Therefore, the present invention enables the user to open the cavity assembly 100 by the child lock structure, and thus two-step door opening operations must be performed before opening the cavity assembly 100. Therefore, on one hand, a certain prompting effect can be achieved for a user, on the other hand, the situation that the cavity assembly 100 is opened by a child by mistake can be prevented, and the use safety of the cooking utensil is greatly improved.

As shown in connection with fig. 3, 4, 5 and 6, in one possible embodiment, when the operation member 700 is in the first position, the stopper 600 is located at a side portion of the operation member 700, and the stopper 600 restricts the operation member 700 from moving in the first direction; when the operating member 700 is in the second position, the operating member 700 clears the stop 600.

In this embodiment, when the user pushes the operation member 700 toward the first direction, the operation member 700 abuts against the stopper 600, and the stopper 600 restricts the movement of the operation member 700 along the first direction, so that the operation member 700 cannot push the key assembly 500, and thus the door opening operation cannot be completed.

When the cavity assembly 100 needs to be opened, the user needs to drive the operation member 700 to move along the second direction, so that the operation member 700 is far away from the limiting member 600, the limiting member 600 does not limit the movement of the operation member 700 along the first direction, namely, the limitation of the operation member 700 is released, at this time, the user can push the operation member 700 towards the second direction, the operation member 700 drives the key assembly 500 to move, and the interlocking assembly 400 can push the lock catch 300 to be separated from the buckling position, so that the door opening action is completed.
