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.

The locking assembly 100 and the cooking appliance 200 according to some embodiments of the present application are described below with reference to fig. 1 to 42.

Example 1:

as shown in fig. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13, an embodiment of the first aspect of the present application provides a locking assembly 100, where the locking assembly 100 includes a base plate 110, a door 120 and a lock structure 130.

The door 120 is positioned at one side of the base plate 110, and the door 120 is provided with a door hook 122.

The lock structure 130 is disposed on the base 110, and the lock structure 130 includes a first mating member 134 and a second mating member 132.

The first engagement member 134 is movable relative to the base plate 110 between a first position and a second position.

The second fitting 132 is movable between a restricting position restricting the movement of the door hook 122 and a releasing position releasing the restriction of the movement of the door hook 122.

Wherein, in the first position, the first engaging member 134 limits the movement of the second engaging member 132 from the limiting position to the releasing position, and in the second position, the first engaging member 134 releases the limitation of the movement of the second engaging member 132, and the second engaging member 132 can move from the limiting position to the releasing position.

In detail, the locking assembly 100 includes a base plate 110, a door 120, and a locking structure 130.

Such that upon locking the door 120, the first engagement member 134 restricts movement of the second engagement member 132 in the first position, specifically, movement of the second engagement member 132 from the restricting position to the releasing position, i.e., the second engagement member 132 remains in the restricting position and cannot move to the releasing position. When the first fitting is located at the limiting position, the second fitting 132 limits the movement of the door hook 122 to block the door 120, and cannot open the door 120, and at this time, even if the child pulls the door 120, the door 120 cannot be unlocked. That is, the door 120 and the lock structure 130 cooperate to realize the child lock, and the door 120 cannot be opened when the first engaging member 134 is in the first position and engages with the second engaging member 132.

When the first matching piece 134 is at the second position, the first matching piece 134 releases the restriction on the movement of the second matching piece 132, the second matching piece 132 can move from the restriction position to the release position, when the second matching piece 132 moves to the release position, the restriction on the door hook 122 can be released, the door body 120 can be opened, and at the moment, the purpose of unlocking the door body 120 can be achieved by pulling the door body 120.

The arrangement can effectively solve the problem of unlocking the door 120 by the child touching the key or the door 120 in the related art, so that the locking assembly 100 has the function of two-step door opening, and the safety and reliability of the cooking appliance 200 comprising the locking assembly 100 can be ensured.

It will be appreciated that the second mating element 132 is movable between a restricting position that restricts movement of the door hook 122 and a releasing position that releases the restriction of movement of the door hook 122. When the second matching piece 132 is at a position other than the release position, the door 120 is in a state of being limited to move. That is, in the case where the second engaging member 132 moves to the restricting position and engages with the door hook 122 of the door 120, the door 120 cannot be opened even if the door 120 is pulled, i.e., the door 120 is not unlocked by an external force, thereby fundamentally solving the problem that a child touches the key by mistake or unlocks the door 120 by touching the door 120.

Specifically, the lock structure 130 is disposed on the base plate 110, and the door body 120 is disposed on one side of the base plate 110, which can ensure the matching dimensions of the lock structure 130 and the door body 120, and further ensure the matching dimensions of the second matching member 132, the first matching member 134 and the door hook 122, so that when the second matching member 132 is in the limiting position, the door body 120 can be effectively limited to move, and an effective and reliable structural support is provided.

Example 2:

as shown in fig. 1 to 12, embodiment 2 provides a lock assembly 100 on the basis of embodiment 1, the lock assembly 100 including a base plate 110, a door 120, and a lock structure 130.

Further, as shown in fig. 3, 5, 6, 7, 8, 9, 10, 11, 12, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 28, 29, 30 and 31, the lock structure 130 further includes a base 136, a first support 162 and a driving member 164.

The base 136 is disposed on the substrate 110.

The first supporting member 162 is rotatably connected to the base 136, and the first matching member 134 is disposed on the first supporting member 162.

The driving member 164 is disposed on the first supporting member 162, the driving member 164 extends out of the outer surface of the base plate 110 through the opening, and the driving member 164 is used to drive the first matching member 134 to move between the first position and the second position.

In detail, the lock structure 130 further includes a base 136, a first support 162, and a driver 164. The first matching element 134 and the driving element 164 are both disposed on the first supporting element 162. Because the first supporting member 162 is rotatably connected to the base 136, when the driving member 164 drives the first supporting member 162 to rotate relative to the base 136, the first matching member 134 also rotates along with the first supporting member 162 to move between the first position and the second position.

Specifically, the driving member 164 protrudes out of the outer surface of the base plate 110 through the opening, and an external force acts on the driving member 164, so that the driving member 164 moves relative to the base plate 110, and further drives the first supporting member 162 to rotate relative to the base 136, so as to drive the first matching member 134 to rotate.

It can be appreciated that after the door 120 is locked, the first engaging member 134 is located at the first position, and the first engaging member 134 limits the movement of the second engaging member 132, so that the door 120 cannot be opened. By pulling the driving member 164, the driving member 164 drives the first supporting member 162 to rotate, the first supporting member 162 rotates to drive the first matching member 134 to move from the first position to the second position, the second matching member 132 can move from the limiting position to the releasing position, and the door body 120 can be opened, at this time, the purpose of unlocking the door body 120 can be achieved by pulling the door body 120.

Specifically, the cross-sectional area of the opening is greater than the cross-sectional area of the driver 164, providing structural support for the movement of the driver 164 relative to the opening.

Specifically, one of the first support member 162 and the seat 136 is provided with a shaft, and the other of the first support member 162 and the seat 136 is provided with a shaft hole, and the shaft is rotatably connected with the shaft hole, so as to fulfill the aim of rotatably connecting the first support member 162 with the seat 136.

Further, as shown in fig. 28 and 31, a portion of the first fitting 134 is located at one side of the driving member 164 in the rotation direction of the first supporting member 162.

Wherein, by reasonably setting the engaging structures of the first engaging member 134 and the driving member 164, a portion of the first engaging member 134 is located at one side of the driving member 164 along the rotation direction of the first supporting member 162. This arrangement allows the driving member 164 to rotate through a small angle, thereby allowing the first mating member 134 and the second mating member 132 to be quickly abutted or quickly separated. Facilitating the ease of operating the locking assembly 100.

Example 3:

as shown in fig. 1 to 12, embodiment 3 provides a lock assembly 100 on the basis of embodiment 1 or embodiment 2, the lock assembly 100 including a base plate 110, a door 120, and a lock structure 130.

Further, as shown in fig. 3, 5, 6, 9, 11 and 18, the lock structure 130 further includes: the connecting structure 138 is disposed on the base 136, and the second mating member 132 is rotatably connected to the connecting structure 138.

In detail, the lock structure 130 further includes a connection structure 138, the connection structure 138 is disposed on the base 136, and the second mating member 132 is rotatably connected to the connection structure 138, and the second mating member 132 rotates relative to the connection structure 138 to move between a restricting position for restricting movement of the door hook 122 and a releasing position for releasing movement of the door hook 122.

Example 4:

as shown in fig. 1 to 12, embodiment 4 provides a lock assembly 100 on the basis of embodiment 3, the lock assembly 100 including a base plate 110, a door 120, and a lock structure 130.

The lock structure 130 further includes: the connecting structure 138 is disposed on the base 136, and the second mating member 132 is rotatably connected to the connecting structure 138.

Further, as shown in fig. 18, the second fitting 132 is provided with a stopper 150, and the door hook 122 is provided with a stopper fitting; in the first position, at least a portion of the stop portion 150 abuts against the top of the stop mating portion, and the second mating member 132 abuts against the top of the first mating member 134.

In detail, the second fitting 132 is provided with a stopper 150, and the door hook 122 is provided with a stopper fitting. The second fitting 132 restricts the movement of the door hook 122 by the stopper 150. For example, when the second engaging member 132 is in the limiting position, at least a portion of the stopping portion 150 abuts against the top of the stopping engaging portion of the door hook 122 to function as stopping the upward movement of the door hook 122.

Further, as shown in fig. 18 and 38, the second mating member 132 includes a first mating segment 146 and a second mating segment 148, the first mating segment 146 and the second mating segment 148 being located on either side of the connecting structure 138.

The weight of the first matching section 146 is smaller than that of the second matching section 148, and the stop part 150 is arranged on the first matching section 146; wherein in the first position, the first engagement member 134 limits movement of the second engagement section 148 and the stop 150 limits movement of the door hook 122.

Wherein, the second mating member 132 includes a first mating segment 146 and a second mating segment 148, and the second mating member 132 and the structure of the connection structure 138 are reasonably configured, so that the first mating segment 146 and the second mating segment 148 are located at two sides of the connection structure 138, that is, the first mating segment 146 is located at a first side of the connection structure 138, the second mating segment 148 is located at a second side of the connection structure 138, and the first side of the connection structure 138 and the second side of the connection structure 138 are correspondingly configured.

Because the weight of the first engaging section 146 is smaller than that of the second engaging section 148, when the first engaging member 134 moves to the second position, that is, when the first engaging member 134 and the second engaging member 132 are separated, the second engaging section 148 of the second engaging member 132 presses the first engaging section 146 upwards under the action of gravity, so that the stop portion 150 on the first engaging section 146 is separated from the door hook 122 of the door 120, and at this time, the door 120 can be opened, and at this time, the purpose of unlocking the door 120 can be achieved by pulling the door 120.

When the first engaging member 134 moves to the first position, the first engaging member 134 limits the movement of the second engaging section 148 along the gravity direction, and the stop portion 150 on the first engaging section 146 limits the upward movement of the door hook 122, thereby blocking the door hook 122 and preventing the door body 120 from being opened, and at this time, even if the child pulls the door body 120, the door body 120 cannot be unlocked.

This set up the structure of the second mating part 132 of reasonable setting, when guaranteeing that the second mating part 132 can be in the restriction position that restriction door hook 122 removed and remove the release position that restriction door hook 122 removed and move, avoided being used for resetting the material input of second mating part 132, have the advantage of being convenient for assemble, low in production cost.

Example 5:

as shown in fig. 1 to 12, embodiment 5 provides a lock assembly 100 on the basis of embodiment 3, the lock assembly 100 including a base plate 110, a door 120, and a lock structure 130.

Further, as shown in fig. 17, 18, 19, 22, 23, 24, 26, 27, 34, 35, 39, 40, 41 and 42, the connection structure 138 includes a second support 140 and a cover 142.

The second supporting member 140 is disposed on the base 136.

The cover 142 is connected with the second supporting member 140, a mounting channel 144 is surrounded between the cover 142 and the second supporting member 140, the second matching member 132 penetrates through the mounting channel 144, and the second matching member 132 is rotatably connected with the wall surface of the mounting channel 144.

In detail, the connection structure 138 includes a second support 140 and a cover 142, the second support 140 and the cover 142 are connected, and the second support 140 and the cover 142 cooperate to enclose a mounting channel 144.

The second mating member 132 extends through the mounting channel 144, and the second mating member 132 is rotatably coupled to a wall surface of the mounting channel 144, i.e., the second mating member 132 is rotatable relative to the mounting channel 144. It will be appreciated that, since the second fitting 132 penetrates the mounting channel 144, the wall surface of the mounting channel 144 can limit the rotation angle of the second fitting 132. So that the second mating element 132 can effectively move between the restricting position and the releasing position.

Specifically, one of the walls of the second fitting 132 and the mounting channel 144 is provided with a rotation shaft, and the other of the wall of the second fitting 132 and the wall of the mounting channel 144 is provided with a shaft hole, and the rotation shaft is rotatably connected with the shaft hole, so that the second fitting 132 can rotate relative to the mounting channel 144.

Specifically, the cross-sectional area of the mounting channel 144 is greater than the cross-sectional area of the second mating member 132, providing structural support for the second mating member 132 to be able to rotate relative to the mounting channel 144.

Specifically, the second support 140 and the cover 142 are detachably connected, such as screwed, riveted, magnetically connected, plugged, or the like. This arrangement facilitates assembly and maintenance of the second support 140, the second fitting 132, and the cover 142 while ensuring reliability of connection of the second support 140 and the cover 142.

Example 6:

as shown in fig. 1 to 12, embodiment 6 provides a lock assembly 100 on the basis of embodiment 3, the lock assembly 100 including a base plate 110, a door 120, and a lock structure 130.

Further, as shown in fig. 40, the connection structure 138 is provided with a first limit rib 154 and a second limit rib 156.

The first limiting rib 154 and the second limiting rib 156 are located on the same side of the second matching piece 132, and the first limiting rib 154 and the second limiting rib 156 are used for limiting the rotation angle of the second matching piece 132.

Wherein, the distance from the first spacing rib 154 to the top wall of the connection structure 138 is smaller than the distance from the second spacing rib 156 to the top wall of the connection structure 138.

In detail, the second support 140 is provided with a first limit rib 154 and a second limit rib 156. Through the structure of reasonable setting first spacing muscle 154, second spacing muscle 156 and second cooperation spare 132 for first spacing muscle 154 and second spacing muscle 156 are located the same side of second cooperation spare 132, and the distance of first spacing muscle 154 to the roof of connection structure 138 is less than the distance of second spacing muscle 156 to the roof of connection structure 138. That is, in the height direction of the second supporting member 140, the position height of a portion of the first stopper rib 154 is higher than the position height of the second stopper.

Specifically, when the second mating member 132 is located at the limiting position, the first limiting rib 154 can limit the rotation angle of the second mating member 132, so that the second mating member 132 cannot continue to rotate in the counterclockwise direction, and the mating dimension of the second mating member 132 and the door hook 122 can be ensured.

Specifically, when the second mating member 132 is located at the release position, the second limiting rib 156 can limit the rotation angle of the second mating member 132, so that the second mating member 132 cannot continue to rotate clockwise, and the mating dimension of the second mating member 132 and the door hook 122 can be ensured.

Specifically, the first stop rib 154 and the second stop rib 156 are both located at the bottom of the second mating element 132.

Example 7:

as shown in fig. 1 to 12, embodiment 7 provides a lock assembly 100 on the basis of embodiment 3, the lock assembly 100 including a base plate 110, a door 120, and a lock structure 130.

Further, as shown in fig. 15, 16, 19, 20, 21 and 22, the connection structure 138 is rotatably connected to the base 136; the lock structure 130 further includes a reset member 158, the reset member 158 coupled to the seat body 136 and the coupling structure 138, the reset member 158 configured to actuate the second mating member 132 from the release position back to the restricting position.

In detail, the lock structure 130 further includes a reset member 158, the reset member 158 is connected to the seat body 136, and the reset member 158 is connected to the connection structure 138. The return member 158 can return the second mating member 132 from the release position to the restricting position.

That is, both the housing 136 and the connecting structure 138 are connected to the return member 158, and the housing 136 and the connecting structure 138 serve as carriers to support and secure the return member 158. The return member 158 provides a powered support for the return of the second mating member 132 from the release position to the restricting position, thereby providing structural assurance that the second mating member 132 can move between the restricting position and the release position.

Specifically, when the door body 120 is closed, the door hook 122 contacts the second fitting 132 and pushes the second fitting 132. Because the connecting structure 138 is rotatably connected to the base 136, the connecting structure 138 rotates under the external force to drive the second mating member 132 to move from the restricting position to the releasing position.

After closing the door, the second mating member 132 returns from the release position to the restricting position under the action of the reset member 158 to limit the door hook 122.

That is, when the door body 120 is closed, the front end of the door hook 122 of the door body 120 will push against the second matching member 132 to move backward, the door hook 122 will enter the locking slot of the base plate 110 after the door body 120 is completely closed, and at this time, the second matching member 132 moving backward due to the action of the door hook 122 during the door closing process will move forward again due to the reset function of the reset member 158 until moving to the door hook 122, which is the automatic locking process after the door body 120 is closed. This arrangement allows the lock structure 130 to have an automatic locking function, enriching the functions and performance of the product.

Specifically, the return member 158 includes a tension spring.

Further, as shown in fig. 36, the base 136 is provided with a stop 160, and the connection structure 138 is located between the stop 160 and the reset member 158, and the stop 160 is used for limiting the rotation angle of the connection structure 138.

Wherein, the seat 136 is provided with a stop 160, and since the connecting structure 138 is located between the stop 160 and the reset member 158, that is, the stop 160 can limit the rotation angle of the connecting structure 138 when the second mating member 132 is in the limiting position, the connecting structure 138 will not continue to rotate, so as to ensure the mating dimension of the second mating member 132 and the door hook 122.

Example 8:

as shown in fig. 1 to 12, embodiment 8 provides a lock assembly 100 on the basis of embodiment 2, the lock assembly 100 including a base plate 110, a door 120, and a lock structure 130.

Specifically, when the external force on the driving member 164 is removed and the driving member 164 is located in the first area, the elastic member 184 drives the first engaging member 134 to return from the second position to the first position to limit the second engaging member 132.

Further, the elastic member 184 can limit the first mating element 134 to the second position when the driving element 164 is located in the second region. That is, when the user does not need to use the child lock function, the driving member 164 is moved to the second region so that the second mating member 132 is in the disabled state. The setting can meet different use demands of users, and improves the use applicability and the use function of the product.

When the elastic member 184 connects the first connecting portion 166 and the second connecting portion 168, the elastic member 184, the first connecting portion 166 and the second connecting portion 168 cooperate, so that when the driving member 164 is located in the first area, the elastic member 184 can drive the first matching member 134 to return from the second position to the first position, and when the driving member 164 is located in the second area, the elastic member 184 can limit the first matching member 134 to the second position, thereby providing effective and reliable structural support.

Specifically, the first connection portion 166 includes a first connection post, and the second connection portion 168 includes a second connection post.

Specifically, a first side of the rotation center 169 of the first support and a second side of the rotation center 169 of the first support are disposed opposite to each other.

Further, as shown in fig. 22, 25, 29, 30 and 31, the first support member 162 is provided with a relief notch 170, and the second connection portion 168 is located at the relief notch 170, and the relief notch 170 is configured to relieve the elastic member 184 when the driving member 164 moves.

Wherein, the first supporting member 162 is provided with an avoidance gap 170, the second connecting portion 168 is located at the avoidance gap 170, and the avoidance gap 170 has the effect of avoiding the elastic member 184, so that when the driving member 164 moves, the first supporting member 162 does not interfere with the elastic member 184, and the use function of the elastic member 184 can be ensured.

Further, as shown in fig. 18, 23, 25, 29, 30 and 31, the lock structure 130 further includes a protrusion 172, where the protrusion 172 connects the first support 162 and the driving member 164, and the protrusion 172 is located at one side of the avoidance gap 170.

In detail, the lock structure 130 further includes a protrusion 172, and the protrusion 172 connects the first support 162 and the driving member 164. The protrusion 172 has the function of enhancing the strength of the connection structure 138 of the first support member 162 and the driving member 164, preventing the locking assembly 100 from being deformed, and ensuring the matching size of the product.

In addition, the protrusion 172 is located at a side of the relief notch 170 away from the first connecting portion 166, and the protrusion 172 does not interfere with the elastic member 184.
