Description

Technical Field

[0001] The present invention relates to the technical field of locking devices, and in particular to a locking assembly and a cooking utensil. Background Art

[0002] In the related art, the microwave oven can be opened by lightly pulling the door. Children may easily touch the buttons or the door handle by mistake and be easily scalded by the heated food, which poses a safety hazard. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a locking assembly.

[0005] A second aspect of the present invention provides a cooking appliance.

[0006] In view of this, the first aspect of the present invention proposes a locking assembly, comprising: a mounting base; a locking member; a door body, located on one side of the mounting base, the door body being provided with a door hook, the door hook cooperating with the locking member to lock or unlock the door body; a lock structure, provided on the mounting base, and the lock structure being connected to the locking member, the lock structure comprising a trigger member and a limit member, the trigger member being used to drive the limit member to move between a first position and a second position; wherein, in the first position, the limit member limits the movement of the door hook, and in the second position, the limit member releases the restriction on the door hook, and the door hook can be separated from the locking member.

[0007] A locking assembly provided by the present invention includes a mounting base, a locking member, a door body and a lock structure. The lock structure includes a trigger member and a limit member. The trigger member can drive the limit member to move between a first position and a second position.

[0008] By properly configuring the coordination between the door hook and the lock structure, after the door is locked, the stopper in the first position blocks the door hook, preventing it from separating from the lock member. At this point, even if a child pulls on the door, the door cannot be unlocked. In other words, the door hook, lock member, and lock structure work together to achieve a double lock. When the stopper is in the first position, restricting the movement of the door hook, the door cannot be unlocked. When the stopper is in the second position, the stopper releases its restraint on the door hook, allowing it to separate from the lock member. At this point, the door can be unlocked by pulling on it.

[0009] This setting can effectively solve the problem in related technologies that children accidentally touch the buttons or the door and unlock the door, and can ensure the safety and reliability of the use of cooking appliances.

[0010] It is understood that the stopper is movable between a first position, which restricts the movement of the door hook, and a second position, which releases the restriction on the door hook. When the stopper is in any position other than the second position, the door hook is restricted in its movement. In other words, when the stopper is in the first position, restricting the movement of the door hook, even pulling on the door body will not disengage the door hook from the locking member. In other words, the door body will not be unlocked by external force, fundamentally solving the problem of children accidentally unlocking the door by touching the button or the door body.

[0011] Specifically, the lock structure is connected to the locking member. This setting can ensure the matching size of the lock structure and the door body, and further ensure the matching size of the lock structure and the door hook, providing effective and reliable structural support for effectively limiting the movement of the door hook when the limit member is in the first position.

[0012] The locking assembly according to the present invention may also have the following additional technical features:

[0013] In the above technical solution, further, the trigger member is used to drive the limiting member to move along the first direction; when in the first position, the limiting member limits the door hook from moving along the second direction; wherein the first direction is different from the second direction.

[0014] In this technical solution, by rationally arranging the operating trajectories of the stopper and the door hook, the stopper moves in a first direction and the door hook moves in a second direction, with the first direction being different from the second direction. In other words, the stopper and the door hook move in different directions. This arrangement provides effective and reliable structural support for the stopper to effectively retain the door hook in its first position, reduces machining precision requirements for the lock structure, facilitates manufacturing, and effectively prevents situations where the stopper fails to effectively retain the door hook in its first position.

[0015] In any of the above technical solutions, further, the first direction is perpendicular to the second direction.

[0016] In this technical solution, the first direction is perpendicular to the second direction, for example, the first direction is a horizontal direction, and the second direction is a vertical direction (specifically, the vertical direction is parallel to the direction of gravity).

[0017] In any of the above technical solutions, further, the limiting member is provided with a stop portion, and the door hook is provided with a stop matching portion; when in the first position, at least a portion of the stop portion abuts against the top of the stop matching portion.

[0018] In this technical solution, the position limiting member is provided with a stop portion, which limits the movement of the door hook through the stop portion. For example, when the position limiting member is in the first position, at least a portion of the stop portion abuts against the top of the stop engaging portion of the door hook, thereby preventing the door hook from moving upward.

[0019] Specifically, when the limit member is in the second position, the stop portion is located on the peripheral side of the door hook, and the limit member is separated from the door hook to release the external force of the limit member on the door hook, thereby releasing space for the door hook to move and providing structural support for unlocking the door body.

[0020] In any of the above technical solutions, further, the triggering member can rotate relative to the locking member to drive the limiting member to move.

[0021] In this technical solution, the trigger member can rotate relative to the locking member. By rotating the trigger member, the trigger member can drive the limit member to move. This setting provides effective and reliable structural support for the trigger member to drive the limit member to move between the first position and the second position in the horizontal direction.

[0022] In any of the above technical solutions, the lock structure further includes: a transmission member, the transmission member includes a transmission housing and a first tooth portion, the first tooth portion is rotatably connected to the transmission housing, and the trigger member is connected to the first tooth portion; the limiting member is provided with a matching hole, a second tooth portion is provided on the hole wall of the matching hole, the first tooth portion is located in the matching hole, and the first tooth portion is engaged with the second tooth portion.

[0023] In this technical solution, the lock structure also includes a transmission member, which includes a transmission housing and a first tooth portion. The limiting member is provided with a matching hole, and the hole wall of the matching hole is provided with a second tooth portion. By reasonably arranging the matching structure of the transmission housing, the first tooth portion, the second tooth portion and the trigger member, the first tooth portion of the transmission member is located in the matching hole of the limiting member, and the first tooth portion is engaged with the second tooth portion. In this way, when the trigger member is rotated, the trigger member drives the first tooth portion to rotate, and the first tooth portion drives the second tooth portion to move. Since the position of the transmission housing and the locking member of the device body is fixed, the position of the first tooth portion and the device body is fixed, and the limiting member can move between the first position and the second position under the action of the first tooth portion.

[0024] In any of the above technical solutions, further, the trigger member includes a connecting tube and a limiting portion, the limiting portion is connected to the connecting tube, and the limiting portion is located on the circumferential side of the connecting tube; the transmission member is provided with a connecting column, at least a portion of the connecting column extends into the connecting tube, and the connecting column is connected to the first tooth portion.

[0025] In this technical solution, the trigger member includes a connecting tube and a stopper. The stopper is connected to the connecting tube and located around the connecting tube. Specifically, the stopper abuts against the wall of the cooking appliance body, limiting the movement of the trigger member relative to the appliance body. This provides effective and reliable structural support to ensure the proper fit between the lock structure and the door hook.

[0026] Furthermore, the transmission member is provided with a connecting post, at least a portion of which extends into the connecting tube and is connected to the first tooth portion. In other words, the connecting post and the connecting tube are cooperatively connected. The connecting tube drives the connecting post to rotate, and the connecting post drives the first tooth portion to rotate.

[0027] Specifically, the shape of the cross section of the connecting column includes any one of the following or a combination thereof: arch, ellipse and polygon. Therefore, after the connecting tube is connected to the connecting column, the connecting column will not rotate relative to the connecting tube, so that the connecting column can rotate under the rotation of the connecting tube, and there will be no relative rotation between the connecting column and the connecting tube, providing effective and reliable structural support for the trigger member to drive the limit member to move.

[0028] In any of the above technical solutions, further, the limiting member is further provided with a bolt hook, which is used to limit the door hook when in the first position; wherein the first tooth portion and the second tooth portion are both located between the bolt hook and the trigger member.

[0029] In this technical solution, the limiting member is further provided with a bolt hook, which is used to limit the door hook in the first position, that is, a part of the outer surface of the bolt hook abuts against the outer surface of the door hook.

[0030] Furthermore, the first tooth portion and the second tooth portion are both located between the bolt hook and the trigger member. While ensuring the effectiveness and feasibility of the first tooth portion driving the second tooth portion to move, there will be no interference between the bolt hook and the first tooth portion and the second tooth portion, thereby ensuring that the trigger member can drive the limit member to move between the first position and the second position.

[0031] In any of the above technical solutions, the lock structure further includes: a cover plate connected to the transmission housing, the first tooth portion and the second tooth portion are both located between the cover plate and the transmission housing, the cover plate is provided with an opening, and the bolt hook extends out of the outer surface of the cover plate through the opening.

[0032] In this technical solution, the lock structure also includes a cover plate, which is connected to the transmission housing. The cover plate and the transmission housing enclose a cavity suitable for accommodating the first and second tooth portions. That is, the first and second tooth portions are both located between the cover plate and the transmission housing. The cover plate and the transmission housing protect the first and second tooth portions located therein, preventing external forces from directly acting on the first and second tooth portions, which helps extend the product's service life. This arrangement also reduces the probability of moisture, dirt, etc. entering the connection between the first and second tooth portions, providing stable and reliable structural support for the effective engagement of the first and second tooth portions.

[0033] In any of the above technical solutions, further, the trigger member drives the limiting member to move from the first position to the second position, and the corresponding rotation angle is greater than or equal to 60°.

[0034] In this technical solution, by rationally configuring the matching structure of the trigger and the limiter, the trigger-driven limiter can rotate at an angle of at least 60° from the first position to the second position. This means that the trigger must rotate at least 60° to move the limiter from the first position to the second position. This reduces the probability of the limiter moving to the second position due to accidental activation of the trigger.

[0035] Specifically, the rotation angle corresponding to the trigger member driving the limit member to move from the first position to the second position includes 65°, 70°, 75°, 80°, 85°, 90°, etc., which are not listed here one by one.

[0036] In any of the above technical solutions, further, the trigger member is provided with an indicator portion, and the indicator portion is used to indicate the rotation direction of the trigger member.

[0037] In this technical solution, the trigger member is provided with an indicator portion, which displays the rotation direction of the trigger member so that the user can understand the rotation direction of the rotating trigger member, and facilitates the user to drive the limit member to move between the first position and the second position in a targeted manner according to actual needs.

[0038] In any of the above technical solutions, further, the shape of the indicator portion includes any one of the following or a combination thereof: raindrop shape, triangle shape and water drop shape.

[0039] In this technical solution, the shape of the indicator portion includes any one of the following or a combination thereof: raindrop, triangle, and water drop. The smaller end of the raindrop, triangle, or water drop shape can be used to indicate the direction of rotation. This has the advantage of clear indication and legibility.

[0040] In any of the above technical solutions, the lock structure further includes: a timed reset component, which is connected to the limiting component, and is used to restore the limiting component to the first position after a preset time when the limiting component is in the second position.

[0041] In this technical solution, the lock structure also includes a timed reset component, which is connected to the limiting component. The timed reset component provides power support for the limiting component to return from the second position to the first position, thereby providing structural guarantee for the limiting component to move between the first position and the second position.

[0042] Specifically, when the door is closed, the stopper engagement portion of the door hook contacts the stopper, pushing the stopper from the first position to the second position. After a preset time, the stopper returns from the second position to the first position under the action of the timed reset element, thereby retaining the door hook. In other words, when the door is closed, the front end of the door hook pushes against the stopper, causing it to move backward. Once the door is fully closed, the door hook enters the locking element. At this point, the stopper, which was moved backward by the door hook during the closing process, is reset by the timed reset element, causing it to move forward again until it reaches the door hook, thus achieving the desired function of retaining the door hook. This is the process of automatic locking after closing the door. This arrangement gives the lock structure an automatic locking function, enriching the product's functionality and performance.

[0043] It is understandable that the timing reset member has the function of resetting the limit member and also has the function of delaying. That is, when the limit member is in the second position, the positioning reset member will drive the limit member to return to the first position after a preset time.

[0044] In any of the above technical solutions, further, a timing reset member is provided in the transmission housing, and the timing reset member is connected to the first tooth portion.

[0045] In this technical solution, the timing reset member is disposed in the transmission housing and connected to the first tooth portion. The transmission housing supports and secures the timing reset member. The timing reset member drives the first tooth portion to rotate in a direction opposite to the direction in which the trigger member drives the first tooth portion to rotate.

[0046] A second aspect of the present invention provides a cooking utensil, comprising: a locking assembly according to any technical solution in the first aspect.

[0047] The cooking utensil provided by the present invention includes the locking assembly of any technical solution in the first aspect, and therefore has all the beneficial effects of the above-mentioned locking assembly, which will not be described one by one here.

[0048] In the above technical solution, further, the locking assembly also includes: an appliance body, the appliance body includes a mounting base plate, and the locking member is arranged on the appliance body; the door body is connected to the appliance body in an openable and closable manner; the locking member is located in the appliance body; and a part of the trigger member extends out of the outer surface of the appliance body.

[0049] In this technical solution, the door and the appliance body enclose a cooking cavity. When the door is unlocked, food can be placed in the cooking cavity and taken out from the cooking cavity.

[0050] Furthermore, a portion of the trigger member extends out of the outer surface of the device body. Therefore, the trigger member can be manipulated through the outer surface of the device body to drive the limit member to move, so that the limit member can move between the first position and the second position.

[0051] In any of the above technical solutions, further, the top plate of the device body is a mounting substrate, and a portion of the trigger member extends out of the outer top wall of the device body; the portion of the trigger member located outside the device body is formed with an indicator portion of a lock structure; and the limiting portion of the lock structure abuts against the wall surface of the device body.

[0052] In this technical solution, the top plate of the appliance body serves as the mounting substrate, and a portion of the trigger member extends out of the outer top wall of the appliance body. That is, the trigger member is to be operated from the top of the appliance body. This arrangement enables the portion of the trigger member extending out of the outer surface of the appliance body to be at a higher height from the ground. In this way, children cannot easily touch the trigger member, thereby further reducing the probability of children accidentally touching the trigger member.

[0053] Furthermore, the part of the trigger member located outside the device body is formed with an indicator portion of a lock structure, and the indicator portion is used to display the rotation direction of the trigger member so that the user can understand the rotation direction of the rotating trigger member, and facilitate the user to drive the limit member to move between the first position and the second position in a targeted manner according to actual needs.

[0054] Furthermore, the limiting portion of the lock structure abuts against the wall of the appliance body, and the limiting portion is used to limit the movement distance of the trigger member relative to the appliance body, providing effective and reliable structural support to ensure the matching size of the lock structure and the door hook.

[0055] Specifically, cooking appliances include microwave ovens, ovens, steamers or all-in-one steamers and ovens, etc., which are not listed here one by one.

DETAILED DESCRIPTION

[0070] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0071] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0072] Refer to the following Figures 1 to 10 A locking assembly and cooking appliance 100 are described according to some embodiments of the present invention.

[0073] Example 1:

[0074] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, an embodiment of the first aspect of the present invention provides a locking assembly including a mounting base 180 , a locking member 112 , a door body 120 and a lock structure 130 .

[0075] The door body 120 is located on one side of the mounting base plate 180 . The door body 120 is provided with a door hook 122 . The door hook 122 cooperates with the locking member 112 to lock or unlock the door body 120 .

[0076] The lock structure 130 is disposed on the mounting base 180 and is connected to the locking member 112 . The lock structure 130 includes a trigger member 132 and a limit member 134 . The trigger member 132 is used to drive the limit member 134 to move between the first position and the second position.

[0077] When in the first position, the limiting member 134 limits the movement of the door hook 122 . When in the second position, the limiting member 134 releases the restriction on the door hook 122 , and the door hook 122 can be separated from the locking member 112 .

[0078] In detail, the locking assembly includes a mounting base 180, a locking member 112, a door body 120 and a lock structure 130. The lock structure 130 includes a trigger member 132 and a limit member 134. The trigger member 132 can drive the limit member 134 to move between a first position and a second position.

[0079] By properly configuring the coordination between the door hook 122 and the lock structure 130, after the door 120 is locked, the stopper 134 blocks the door hook 122 in the first position, preventing the door hook 122 from separating from the lock member 112. At this point, even if a child pulls on the door 120, the door 120 cannot be unlocked. In other words, the door hook 122, the lock member 112, and the lock structure 130 cooperate to achieve a double locking effect. When the stopper 134 is in the first position, restricting the movement of the door hook 122, the door 120 cannot be unlocked. When the stopper 134 is in the second position, the stopper 134 releases the restriction on the door hook 122, allowing the door hook 122 to separate from the lock member 112. At this point, the door 120 can be unlocked by pulling on it.

[0080] This configuration can effectively solve the problem in the related art that children may accidentally touch the button or the door 120 and unlock the door 120, thereby ensuring the safety and reliability of the cooking appliance 100.

[0081] It will be appreciated that the stopper 134 is movable between a first position, which restricts the movement of the door hook 122, and a second position, which releases the restriction on the door hook 122. When the stopper 134 is in any position other than the second position, the door hook 122 is always restricted in its movement. In other words, when the stopper 134 is in the first position, restricting the movement of the door hook 122, even pulling on the door 120 will not separate the door hook 122 from the locking member 112. In other words, the door 120 will not be unlocked by external force, thus fundamentally preventing children from accidentally unlocking the door 120 by touching a button or the door 120.

[0082] Specifically, the lock structure 130 is connected to the locking member 112. This setting can ensure the matching dimensions of the lock structure 130 and the door body 120, and further ensure the matching dimensions of the lock structure 130 and the door hook 122, so that the limiting member 134 can effectively limit the movement of the door hook 122 when the limiting member 134 is in the first position, providing effective and reliable structural support.

[0083] Example 2:

[0084] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, based on Example 1, Example 2 provides a locking assembly including a mounting base plate 180 , a locking member 112 , a door body 120 and a lock structure 130 .

[0085] The door body 120 is located on one side of the mounting base 180 . The door body 120 is provided with a door hook 122 . The door hook 122 cooperates with the locking member 112 to lock or unlock the door body 120 .

[0086] The lock structure 130 is disposed on the mounting base 180 and is connected to the locking member 112 . The lock structure 130 includes a trigger member 132 and a limit member 134 . The trigger member 132 is used to drive the limit member 134 to move between the first position and the second position.

[0087] When in the first position, the limiting member 134 limits the movement of the door hook 122 . When in the second position, the limiting member 134 releases the restriction on the door hook 122 , and the door hook 122 can be separated from the locking member 112 .

[0088] Furthermore, the trigger member 132 is used to drive the limiting member 134 to move along a first direction; when in the first position, the limiting member 134 limits the door hook 122 from moving along a second direction; wherein the first direction is different from the second direction.

[0089] Specifically, by rationally arranging the operating trajectories of the stopper 134 and the door hook 122, the stopper 134 moves in a first direction, while the door hook 122 moves in a second direction, with the first direction being different from the second direction. In other words, the stopper 134 and the door hook 122 move in different directions. This arrangement provides effective and reliable structural support for the stopper 134 to effectively retain the door hook 122 in the first position, reduces the machining precision requirements for the lock structure 130, facilitates manufacturing, and effectively prevents situations where the stopper 134 fails to effectively retain the door hook 122 in the first position.

[0090] Furthermore, the first direction is perpendicular to the second direction.

[0091] The first direction is perpendicular to the second direction, for example, the first direction is a horizontal direction, and the second direction is a vertical direction (specifically, the vertical direction is parallel to the direction of gravity).

[0092] Example 3:

[0093] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, based on Example 2, Example 3 provides a locking assembly including a mounting base plate 180 , a locking member 112 , a door body 120 and a lock structure 130 .

[0094] The door body 120 is located on one side of the mounting base 180 . The door body 120 is provided with a door hook 122 . The door hook 122 cooperates with the locking member 112 to lock or unlock the door body 120 .

[0095] The lock structure 130 is disposed on the mounting base 180 and is connected to the locking member 112 . The lock structure 130 includes a trigger member 132 and a limit member 134 . The trigger member 132 is used to drive the limit member 134 to move between the first position and the second position.

[0096] When in the first position, the limiting member 134 limits the movement of the door hook 122 . When in the second position, the limiting member 134 releases the restriction on the door hook 122 , and the door hook 122 can be separated from the locking member 112 .

[0097] The trigger member 132 is used to drive the limiting member 134 to move along a first direction. When in the first position, the limiting member 134 limits the door hook 122 from moving along a second direction. The first direction is different from the second direction.

[0098] Furthermore, if Figure 4 、 Figure 7 and Figure 8As shown, the limiting member 134 is provided with a stop portion 136 , and the door hook 122 is provided with a stop matching portion 124 ; when in the first position, at least a portion of the stop portion 136 abuts against the top of the stop matching portion 124 .

[0099] Specifically, the stopper 136 is provided on the position limiting member 134 to limit the movement of the door hook 122. For example, when the position limiting member 134 is in the first position, at least a portion of the stopper 136 abuts against the top of the stopper engagement portion 124 of the door hook 122, thereby preventing the door hook 122 from moving upward.

[0100] Specifically, when the limit member 134 is in the second position, the stop portion 136 is located on the peripheral side of the door hook 122, and the limit member 134 is separated from the door hook 122 to release the external force of the limit member 134 on the door hook 122, thereby releasing space for the door hook 122 to move and provide structural support for unlocking the door body 120.

[0101] Specifically, the stop fitting portion 124 can cooperate with the stop portion 136 to drive the limiting member 134 to move from the first position to the second position.

[0102] By properly configuring the matching structure of the stop portion 136 and the stop engaging portion 124, the stop engaging portion 124 can cooperate with the stop portion 136 to drive the limiting member 134 from the first position to the second position. That is, when the door is closed, the stop engaging portion 124 of the door hook 122 contacts the stop portion 136 and pushes the limiting member 134 from the first position to the second position. After a predetermined time, the limiting member 134 returns from the second position to the first position under the action of the timed reset member to limit the door hook 122. That is, when the door 120 is closed, the front end of the door hook 122 of the door 120 pushes against the limiting member 134 to move backward. After the door 120 is completely closed, the door hook 122 enters the locking member 112. At this time, the limiting member 134, which has moved 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 timed reset member until it moves to the door hook 122, thus achieving the function of limiting the door hook 122. This is the process of automatic locking after closing the door 120. This arrangement enables the lock structure 130 to have the function of automatic locking, enriching the use function and performance of the product.

[0103] Example 4:

[0104] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, based on any of the above embodiments, embodiment 4 provides a locking assembly including a mounting base plate 180 , a locking member 112 , a door body 120 and a lock structure 130 .

[0105] The door body 120 is located on one side of the mounting base 180 . The door body 120 is provided with a door hook 122 . The door hook 122 cooperates with the locking member 112 to lock or unlock the door body 120 .

[0106] The lock structure 130 is disposed on the mounting base 180 and is connected to the locking member 112 . The lock structure 130 includes a trigger member 132 and a limit member 134 . The trigger member 132 is used to drive the limit member 134 to move between the first position and the second position.

[0107] When in the first position, the limiting member 134 limits the movement of the door hook 122 . When in the second position, the limiting member 134 releases the restriction on the door hook 122 , and the door hook 122 can be separated from the locking member 112 .

[0108] Furthermore, the triggering member 132 can rotate relative to the locking member 112 to drive the limiting member 134 to move.

[0109] In detail, the trigger member 132 can rotate relative to the locking member 112. By rotating the trigger member 132, the trigger member 132 can drive the limit member 134 to move. This setting provides effective and reliable structural support for the trigger member 132 to drive the limit member 134 to move between the first position and the second position in the horizontal direction.

[0110] Furthermore, if Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the lock structure 130 also includes: a transmission member 138, the transmission member 138 includes a transmission housing 140 and a first tooth portion 142, the first tooth portion 142 is rotatably connected to the transmission housing 140, and the trigger member 132 is connected to the first tooth portion 142; the limiting member 134 is provided with a matching hole 144, and a second tooth portion 146 is provided on the hole wall of the matching hole 144, the first tooth portion 142 is located in the matching hole 144, and the first tooth portion 142 is engaged with the second tooth portion 146.

[0111] The lock structure 130 further includes a transmission member 138, which includes a transmission housing 140 and a first tooth portion 142. The stopper 134 is provided with a mating hole 144, and a second tooth portion 146 is provided on the wall of the mating hole 144. By properly arranging the mating structure of the transmission housing 140, the first tooth portion 142, the second tooth portion 146, and the trigger member 132, the first tooth portion 142 of the transmission member 138 is positioned within the mating hole 144 of the stopper 134, and the first tooth portion 142 engages with the second tooth portion 146. Thus, when the trigger member 132 is rotated, the trigger member 132 drives the first tooth portion 142 to rotate, which in turn drives the second tooth portion 146 to move. Because the transmission housing 140 and the locking member 112 of the device body 110 are fixed in position, the first tooth portion 142 and the device body 110 are also fixed in position, and the stopper 134 can move between the first position and the second position under the action of the first tooth portion 142.

[0112] Further, if Figures 4 to 9 As shown, the trigger member 132 includes a connecting tube 156 and a limiting portion 158, the limiting portion 158 is connected to the connecting tube 156, and the limiting portion 158 is located on the circumferential side of the connecting tube 156; the transmission member 138 is provided with a connecting column 160, at least a portion of the connecting column 160 extends into the connecting tube 156, and the connecting column 160 is connected to the first tooth portion 142.

[0113] The trigger member 132 includes a connecting tube 156 and a limiting portion 158. The limiting portion 158 is connected to the connecting tube 156 and is located around the connecting tube 156. Specifically, the limiting portion 158 abuts against the wall of the appliance body 110 of the cooking appliance 100. The limiting portion 158 is used to limit the movement distance of the trigger member 132 relative to the appliance body 110, providing effective and reliable structural support to ensure the matching dimensions of the lock structure 130 and the door hook 122.

[0114] Furthermore, the transmission member 138 is provided with a connecting post 160. At least a portion of the connecting post 160 extends into the connecting tube 156, and the connecting post 160 is connected to the first tooth portion 142. In other words, the connecting post 160 is cooperatively connected with the connecting tube 156. The connecting tube 156 drives the connecting post 160 to rotate, and the connecting post 160 drives the first tooth portion 142 to rotate.

[0115] Specifically, the shape of the cross section of the connecting column 160 includes any one of the following or a combination thereof: an arch, an ellipse and a polygon. Therefore, after the connecting tube 156 is connected to the connecting column 160, the connecting column 160 will not rotate relative to the connecting tube 156, so that the connecting column 160 can rotate under the rotation of the connecting tube 156, and there will be no relative rotation between the connecting column 160 and the connecting tube 156, providing effective and reliable structural support for the trigger member 132 to drive the limit member 134 to move.

[0116] Further, if Figures 4 to 9 As shown, the limiting member 134 is further provided with a latch hook 148 , which is used to limit the door hook 122 in the first position; wherein the first tooth portion 142 and the second tooth portion 146 are both located between the latch hook 148 and the trigger member 132 .

[0117] The limiting member 134 is further provided with a latch hook 148 , which is used to limit the door hook 122 in the first position. That is, a portion of the outer surface of the latch hook 148 abuts against the outer surface of the door hook 122 .

[0118] In addition, the first tooth portion 142 and the second tooth portion 146 are both located between the bolt hook 148 and the trigger member 132. While ensuring the effectiveness and feasibility of the first tooth portion 142 driving the second tooth portion 146 to move, there will be no interference between the bolt hook 148 and the first tooth portion 142 and the second tooth portion 146, which can ensure that the trigger member 132 can drive the limit member 134 to move between the first position and the second position.

[0119] Further, if Figure 7 As shown, the lock structure 130 further includes: a cover plate 150 connected to the transmission housing 140 , the first tooth portion 142 and the second tooth portion 146 are both located between the cover plate 150 and the transmission housing 140 , the cover plate 150 is provided with an opening 152 , and the bolt hook 148 extends out of the outer surface of the cover plate 150 through the opening 152 .

[0120] The lock structure 130 further includes a cover plate 150, which is connected to the transmission housing 140. The cover plate 150 and the transmission housing 140 enclose a cavity suitable for accommodating the first tooth portion 142 and the second tooth portion 146. That is, the first tooth portion 142 and the second tooth portion 146 are both located between the cover plate 150 and the transmission housing 140. The cover plate 150 and the transmission housing 140 protect the first tooth portion 142 and the second tooth portion 146 located therein, preventing external forces from directly acting on the first tooth portion 142 and the second tooth portion 146, thereby extending the service life of the product. This arrangement also reduces the probability of moisture, dirt, etc. entering the connection between the first tooth portion 142 and the second tooth portion 146, providing stable and reliable structural support for the effective engagement of the first tooth portion 142 and the second tooth portion 146.

[0121] Specifically, the cover plate 150 is provided with an opening 152 , and the bolt hook 148 extends out of the outer surface of the cover plate 150 through the opening 152 . The portion of the bolt hook 148 extending out of the outer surface of the cover plate 150 is used to cooperate with the door hook 122 .

[0122] Specifically, if Figure 3 、 Figure 7 、 Figure 8 and Figure 9 As shown, the cover plate 150 is provided with an ear portion 153, and the fastener 170 passes through the ear portion 153 and is connected to the locking member 112. The fastener 170 includes a bolt, a screw and a rivet.

[0123] Example 5:

[0124] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, based on the above-mentioned embodiment 4, embodiment 5 provides a locking assembly including a mounting base plate 180 , a locking member 112 , a door body 120 and a lock structure 130 .

[0125] The door body 120 is located on one side of the mounting base 180 . The door body 120 is provided with a door hook 122 . The door hook 122 cooperates with the locking member 112 to lock or unlock the door body 120 .

[0126] The lock structure 130 is disposed on the mounting base 180 and is connected to the locking member 112 . The lock structure 130 includes a trigger member 132 and a limit member 134 . The trigger member 132 is used to drive the limit member 134 to move between the first position and the second position.

[0127] When in the first position, the limiting member 134 limits the movement of the door hook 122 . When in the second position, the limiting member 134 releases the restriction on the door hook 122 , and the door hook 122 can be separated from the locking member 112 .

[0128] The triggering member 132 can rotate relative to the locking member 112 to drive the limiting member 134 to move.

[0129] Furthermore, the trigger member 132 drives the limiting member 134 to move from the first position to the second position, and the corresponding rotation angle is greater than or equal to 60°.

[0130] Specifically, by properly configuring the matching structure of the trigger member 132 and the limiting member 134, the corresponding rotation angle of the trigger member 132 driving the limiting member 134 from the first position to the second position is greater than or equal to 60 degrees. In other words, the trigger member 132 needs to rotate at least 60 degrees to move the limiting member 134 from the first position to the second position. This reduces the probability of the limiting member 134 moving to the second position due to accidental activation of the trigger member 132.

[0131] Specifically, the rotation angles corresponding to the trigger member 132 driving the limiting member 134 to move from the first position to the second position include 65°, 70°, 75°, 80°, 85°, 90°, etc., which are not listed here one by one.

[0132] Example 6:

[0133] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, based on the above-mentioned embodiment 4, embodiment 6 provides a locking assembly including a mounting base plate 180 , a locking member 112 , a door body 120 and a lock structure 130 .

[0134] The door body 120 is located on one side of the mounting base plate 180 . The door body 120 is provided with a door hook 122 . The door hook 122 cooperates with the locking member 112 to lock or unlock the door body 120 .

[0135] The lock structure 130 is disposed on the mounting base 180 and is connected to the locking member 112 . The lock structure 130 includes a trigger member 132 and a limit member 134 . The trigger member 132 is used to drive the limit member 134 to move between the first position and the second position.

[0136] When in the first position, the limiting member 134 limits the movement of the door hook 122 . When in the second position, the limiting member 134 releases the restriction on the door hook 122 , and the door hook 122 can be separated from the locking member 112 .

[0137] The triggering member 132 can rotate relative to the locking member 112 to drive the limiting member 134 to move.

[0138] Further, if Figure 1 、 Figure 2 、 Figures 4 to 10 As shown, the trigger member 132 is provided with an indicator portion 154 , and the indicator portion 154 is used to indicate the rotation direction of the trigger member 132 .

[0139] In detail, the trigger member 132 is provided with an indicator portion 154, which displays the rotation direction of the trigger member 132 so that the user can understand the rotation direction of the rotating trigger member 132, and facilitates the user to drive the limit member 134 to move between the first position and the second position in a targeted manner according to actual needs.

[0140] Furthermore, the shape of the indicator portion 154 includes any one of the following or a combination thereof: raindrop shape, triangle shape, and water drop shape.

[0141] The shape of the indicator portion 154 includes any one of the following or a combination thereof: raindrop, triangle, and water drop, and the smaller end of the raindrop, triangle, or water drop can be used to indicate the direction of rotation, which has the advantage of clear indication and legibility.

[0142] Specifically, the matching hole 144 includes a first side hole wall and a second side hole wall. The first side hole wall and the second side hole wall are arranged opposite to each other, and both the first side hole wall and the second side hole wall are provided with a second tooth portion 146 .

[0143] Example 7:

[0144] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, based on Example 4, Example 7 provides a locking assembly including a mounting base plate 180 , a locking member 112 , a door body 120 and a lock structure 130 .

[0145] The door body 120 is located on one side of the mounting base 180 . The door body 120 is provided with a door hook 122 . The door hook 122 cooperates with the locking member 112 to lock or unlock the door body 120 .

[0146] The lock structure 130 is disposed on the mounting base 180 and is connected to the locking member 112 . The lock structure 130 includes a trigger member 132 and a limit member 134 . The trigger member 132 is used to drive the limit member 134 to move between the first position and the second position.

[0147] When in the first position, the limiting member 134 limits the movement of the door hook 122 . When in the second position, the limiting member 134 releases the restriction on the door hook 122 , and the door hook 122 can be separated from the locking member 112 .

[0148] The triggering member 132 can rotate relative to the locking member 112 to drive the limiting member 134 to move.

[0149] The lock structure 130 also includes: a transmission member 138, the transmission member 138 includes a transmission housing 140 and a first tooth portion 142, the first tooth portion 142 is rotatably connected to the transmission housing 140, and the trigger member 132 is connected to the first tooth portion 142; the limiting member 134 is provided with a matching hole 144, and a second tooth portion 146 is provided on the hole wall of the matching hole 144, the first tooth portion 142 is located in the matching hole 144, and the first tooth portion 142 is engaged with the second tooth portion 146.

[0150] Furthermore, the lock structure 130 further includes a timed reset component connected to the limiting component 134 , and configured to return the limiting component 134 to the first position after a preset time when the limiting component 134 is in the second position.

[0151] In detail, the lock structure 130 also includes a timed reset component, which is connected to the limit component 134. The timed reset component provides power support for the limit component 134 to return from the second position to the first position, thereby providing structural protection for the limit component 134 to move between the first position and the second position.

[0152] Specifically, when the door is closed, the stop engaging portion 124 of the door hook 122 contacts the stop portion 136, pushing the limiting member 134 from the first position to the second position. After a preset time, the limiting member 134 returns from the second position to the first position under the action of the timed reset member, thereby limiting the door hook 122. In other words, when the door 120 is closed, the front end of the door hook 122 of the door 120 pushes against the limiting member 134 to move backward. After the door 120 is fully closed, the door hook 122 enters the locking member 112. At this time, the limiting member 134, which was moved backward by the action of the door hook 122 during the closing process, is reset by the timed reset member and moves forward again until it reaches the door hook 122, thus achieving the function of limiting the door hook 122. This is the process of automatically locking the door after closing the door 120. This configuration enables the lock structure 130 to have an automatic locking function, enriching the product's functionality and performance.

[0153] It is understandable that the timing reset member has the function of resetting the limit member 134 and also has the function of delaying. That is, when the limit member 134 is in the second position, the positioning reset member will drive the limit member 134 to return to the first position after a preset time.

[0154] Specifically, the timing reset element includes a clockwork spring.

[0155] Furthermore, the timing reset member is disposed on the transmission housing 140 , and the timing reset member is connected to the first tooth portion 142 .

[0156] The timing reset member is disposed in the transmission housing 140 and is connected to the first tooth portion 142. The transmission housing 140 supports and secures the timing reset member. The timing reset member drives the first tooth portion 142 to rotate in a direction opposite to the direction in which the trigger member 132 drives the first tooth portion 142 to rotate.

[0157] Specifically, the preset time is greater than or equal to 30 seconds and less than or equal to 45 seconds.

[0158] Example 8:

[0159] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, an embodiment of the second aspect of the present invention provides a cooking appliance 100, comprising: a locking assembly as in any embodiment of the first aspect.

[0160] In detail, since the cooking appliance 100 includes the locking assembly as in any embodiment of the first aspect, it has all the beneficial effects of the above-mentioned locking assembly, which will not be described one by one here.

[0161] Further, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the locking assembly also includes: an appliance body 110, the appliance body 110 includes a mounting base plate 180, a locking member 112 is provided on the appliance body 110; the door body 120 is connected to the appliance body 110 in an openable and closable manner; the locking member 112 is located inside the appliance body 110; and a portion of the trigger member 132 extends out of the outer surface of the appliance body 110.

[0162] The door body 120 and the appliance body 110 together form a cooking cavity. When the door body 120 is unlocked, food can be placed into the cooking cavity and taken out of the cooking cavity.

[0163] In addition, a portion of the trigger member 132 extends out of the outer surface of the device body 110 , so the trigger member 132 can be manipulated through the outer surface of the device body 110 to drive the limit member 134 to move, so that the limit member 134 can move between the first position and the second position.

[0164] Specifically, a connection hole is provided on the device body 110, and a portion of the trigger member 132 extends out of the outer surface of the device body 110 through the connection hole. By rotating the portion of the trigger member 132 located on the outer surface of the device body 110, the purpose of driving the limit member 134 to move is achieved.

[0165] Furthermore, the top plate of the device body 110 is the mounting base plate 180, and a portion of the trigger member 132 extends out of the outer top wall of the device body 110; the portion of the trigger member 132 located outside the device body 110 forms the indicating portion 154 of the lock structure 130; the limiting portion 158 of the lock structure 130 abuts against the wall surface of the device body 110.

[0166] Among them, the top plate of the device body 110 is the mounting base plate 180, and a part of the trigger member 132 extends out of the outer top wall of the device body 110, that is, the trigger member 132 is to be operated from the top of the device body 110. This setting makes the part of the trigger member 132 extending out of the outer surface of the device body 110 higher from the ground, so that children cannot easily touch the trigger member 132, thereby further reducing the probability of children accidentally touching the trigger member 132.

[0167] In addition, the portion of the trigger member 132 located outside the device body 110 forms an indicator portion 154 of the lock structure 130, and the indicator portion 154 is used to display the rotation direction of the trigger member 132 so that the user can understand the rotation direction of the rotating trigger member 132, and it is convenient for the user to drive the limit member 134 between the first position and the second position in a targeted manner according to actual needs.

[0168] Furthermore, the limiting portion 158 of the lock structure 130 abuts against the wall of the appliance body 110. The limiting portion 158 is used to limit the movement distance of the trigger member 132 relative to the appliance body 110, providing effective and reliable structural support to ensure the matching dimensions of the lock structure 130 and the door hook 122.

[0169] In this embodiment, the limiting portion 158 is located inside the device body 110 , and the limiting portion 158 abuts against the inner wall of the device body 110 .

[0170] In some other embodiments, the limiting portion 158 is located on the outer wall of the device body 110 , and the limiting portion 158 abuts against the outer wall of the device body 110 .

[0171] Specifically, the cooking appliance 100 includes a microwave oven, an oven, a steamer or a steam-bake combination machine, etc., which are not listed here one by one.

[0172] Example 9:

[0173] The cooking appliance 100 includes a cooking appliance body 110, a door 120, and a lock structure 130. The lock structure 130 includes a trigger 132 (e.g., a knob), a transmission member 138 (a timer reset member of the transmission member 138 has a timer reset function), a latch 148, and a cover 150. The lock structure 130 is then fixed to the locking member 112 and the cooking appliance body 110 using screws.

[0174] After the door body 120 is locked, the bolt hook 148 in the lock structure 130 (the bolt hook 148 can only move horizontally back and forth) hinders the upward movement of the door hook 122 (after the door body 120 is locked, the door can only be opened when the door hook 122 on the door body 120 moves upward and disengages from the locking member 112), resulting in the door hook 122 being unable to escape from the locking member 112, that is, the door body 120 cannot be opened.

[0175] A portion of the trigger member 132 of the lock structure 130 extends out of the outer surface of the appliance body 110. In this state, the bolt hook 148 limits the upward movement of the door hook 122, thereby limiting the door body 120 from disengaging the locking member 112, achieving a double locking effect.

[0176] When the door 120 needs to be opened, the trigger member 132 on the rotating device body 110 (the maximum rotation angle of the knob is 360°) acts on the transmission member 138, so that the first tooth portion 142 of the transmission member 138 that cooperates with the bolt hook 148 will act on the second tooth portion 146 of the limiting member 134, causing the bolt hook 148 to move backward and withdraw from the upward movement route of the door hook 122 (the knob needs to complete a rotation angle of at least 60° before the bolt hook 148 can completely disengage from the position that hinders the upward movement of the door hook 122), thereby achieving the unlocking effect.

[0177] The transmission member 138 has a timed reset function. When the trigger member 132 is rotated to a certain angle (e.g., 360°), the latch hook 148 reaches its maximum rearward displacement. At this point, it takes 30 to 45 seconds for the latch hook 148 to reset itself, through the timed reset element of the transmission member 138, to once again block the upward movement of the door hook 122. When the door 120 is closed, the front end of the door hook 122 of the door 120 pushes against the latch hook 148, causing it to move backward. Once the door 120 is fully closed, the door hook 122 enters the locking member 112. At this point, the stopper 134, which had been moved backward by the door hook 122 during the closing process, is re-moved forward by the reset function of the transmission member 138 until it reaches the door hook 122, thereby limiting the movement of the door hook 122. This is how the door 120 automatically locks after closing.
