Description

[0001] The present application relates to the field of kitchen appliances, in particular, to a lock structure and a cooking appliance. BACKGROUND

[0002] After cooking, the user can directly open the door body assembly, but the food just cooked is usually at a high temperature, which may cause the user to be scalded. Especially when children use the cooking appliance to cook food, accidents are more likely to occur.

[0003] In the related art, a lock structure of a button type is used to limit the opening and closing of the door body assembly, but in the case where the door body assembly is opened, the user may accidentally trigger the button type structure, at which time the user cannot close the button type lock structure, resulting in the user being unable to close the door body assembly. SUMMARY

[0004] The present application aims to at least solve one of the technical problems existing in the prior art.

[0005] To this end, the first aspect of the present application provides a lock structure.

[0006] The second aspect of the present application provides a cooking appliance.

[0007] The present application provides a lock structure, comprising: a fixed part; and a locking assembly provided in the other of a cavity assembly and a door body assembly, the locking assembly comprising: a mounting part; a driving part, at least a part of the driving part being provided in the mounting part; a first elastic part, a first end of the first elastic part being connected to the driving part; and a locking part, a second end of the first elastic part being connected to the locking part, the locking part being capable of moving relative to the mounting part under the driving of the driving part and the first elastic part, and being capable of being locked or separated with the fixed part.

[0008] The lock structure provided by the present application comprises a fixed part and a locking assembly. The locking assembly and the fixed part can be used in cooperation to achieve the function of locking and limiting. Specifically, the lock structure provided by the present application can be applied to a cooking appliance and used as a child lock of the cooking appliance.

[0009] In particular, the locking assembly comprises a mounting part, a driving part, a first elastic part and a locking part. The mounting part is externally connected to an object (for example, the door body assembly or the cavity assembly of the cooking appliance); at least a part of the driving part is provided in the mounting part, a first end of the first elastic part is connected to the driving part; a second end of the first elastic part is connected to the locking part. In this way, the driving part can exert a pushing force on the locking part through the first elastic part, so that the locking part moves relative to the mounting part under the driving of the driving part and the first elastic part, and then the locking part is locked with the fixed part through the mounting part.

[0010] Particularly, in the lock structure provided by the present application, the first elastic member is abutted between the driving member and the locking member, thereby realizing the flexible connection between the locking member and the driving member. In this way, when the locking assembly is in the locked position, the locking member can still move towards the side of the driving member due to the presence of the first elastic member.

[0011] Specifically, the fixing member and the locking assembly can be respectively installed to the door body assembly of the cavity assembly, and thus, when the door body assembly is opened, once the user inadvertently closes the locking assembly, the fixing member will be in contact with the locking member in the process of the user closing the door body assembly without switching the working position of the locking member, thereby forcing the locking member to move towards the side of the driving member. In this way, on the one hand, the locking member and the fixing member can be connected and limited, and on the other hand, the connection and limitation of the locking member and the fixing member do not require user operation, thereby greatly improving the use convenience of the locking assembly.

[0012] When the door body assembly is in the closed state, the locking member is in the locked working position; at this time, the locking member is connected and limited with the fixing member, and the user cannot open the door body assembly. Before opening the door body assembly, the connection and limitation between the locking member and the fixing member is released; at this time, the locking member is in the unlocked working position, and the locking member is separated from the fixing member.

[0013] In the process of opening the door body assembly, the door body assembly can be directly driven to separate from the cavity assembly to complete the opening operation; at this time, the locking member is still in the unlocked working position. In the process of closing the door body assembly, the door body assembly can be directly closed, and then the working position of the locking member is switched again, so that the locking member is connected and limited with the fixing member. Moreover, once the user switches the locking member to the locked working position when the door body assembly is opened, the locking member and the driving member are elastically connected due to the abutment of the first elastic member between the locking member and the driving member. In this way, the user does not need to switch the working position of the locking member in advance, and the locking member can still be connected and limited with the fixing member in the process of closing the door body assembly.

[0014] Specifically, the lock structure provided by the present application can be applied to a cooking utensil. After the cooking utensil ends the cooking process, the temperature of the food in the cooking cavity is relatively high, and thus, the user directly opens the door body to take out the food, which has the risk of scalding. Therefore, the locking assembly and the fixing member are matched to make the user open the door body assembly, and the locking member must be pulled out at the same time. In this way, on the one hand, the user can be prompted, and on the other hand, the child can be prevented from mistakenly opening the door body assembly, thereby greatly improving the use safety of the cooking utensil.

[0015] Therefore, the lock structure provided by the present application improves the unlocking difficulty of the lock structure by matching the locking assembly with the fixing member, avoids the user, especially children, from mistakenly opening the door body assembly, and improves the use safety of the cooking appliance applying the lock structure. Moreover, the flexible connection between the driving member and the locking member can ensure the connection and limiting between the locking member and the fixing member when the user mistakenly switches the locking member to the locking position while opening the door body assembly.

[0016] In some possible designs, the locking assembly further includes a guide structure arranged on the mounting member, and at least a part of the driving member is capable of moving along the guide structure and is limited at an end of the guide structure.

[0017] In this design, the locking assembly further includes a guide structure. The guide structure is arranged inside the mounting member, and at least a part of the driving member is in sliding connection with the guide structure and is capable of being limited at an end of the guide structure, so that the locking member stays at the locking position.

[0018] Specifically, the end of the guide structure is provided with a limiting portion, and at least a part of the driving member is capable of moving along the guide structure; when at least a part of the driving member moves to the end of the guide structure, at least a part of the driving member abuts against the limiting portion at the end of the guide structure, so as to limit the locking member at the locking position.

[0019] Specifically, the guide structure includes a guide rib, and the extension direction of the guide rib is consistent with the moving direction of the locking member; at least a part of the driving member is capable of moving along the guide rib, and at least a part of the driving member is capable of abutting against the end of the guide rib, so as to limit the locking member at the locking position.

[0020] In some possible designs, the driving member includes a pressing member arranged in the mounting member and in movable connection with the mounting member, and the pressing member includes a first inclined surface; a moving member in sliding connection with the guide structure, the moving member is connected to the first end of the first elastic member, and the moving member is capable of being limited at the end of the guide structure; wherein the moving member includes a second inclined surface, and the first inclined surface is capable of abutting against the second inclined surface to drive the moving member to switch the position of the locking member.

[0021] In this design, the driving member includes a pressing member and a moving member. The pressing member is in movable connection with the mounting member and is arranged in the mounting member; and at least a part of the pressing member is located on the outer surface of the entire cooking appliance; during the use of the cooking appliance, the position of the locking member can be switched by pressing the pressing member. The moving member is arranged inside the mounting member and is in sliding connection with the guide structure. In addition, the moving member is connected to the first end of the first elastic member, so that the first elastic member is located between the moving member and the locking member. Therefore, during the use of the cooking appliance, the user can press the pressing member, the pressing member drives the moving member to operate, and the moving member drives the locking member to switch the position through the first elastic member.

[0022] Specifically, the pressing piece includes a first inclined surface, and the moving piece includes a second inclined surface. When the user presses the pressing piece, the first inclined surface of the pressing piece is in contact with the second inclined surface of the moving piece. When the pressing piece is pressed for the first time, the moving piece moves along the guide structure; when the moving piece moves to the end of the guide structure, the second inclined surface cooperates with the first inclined surface to drive the moving piece to rotate, and at this time, the moving piece can abut against the limiting portion, and the locking piece is limited in the locked position. When the pressing piece is pressed for the second time, the second inclined surface cooperates with the first inclined surface to drive the moving piece to rotate again, and at this time, the moving piece moves reversely along the guide structure, and then the moving piece is separated from the limiting portion, and the locking piece is switched from the locked position to the unlocked position.

[0023] In some possible designs, the pressing piece includes a key column, and a third protrusion is arranged on the side wall of the key column, and the third protrusion is used for limiting the key column.

[0024] In this design, the pressing piece includes a key column. The side wall of the key column is provided with a third protrusion, and the third protrusion can abut against the end of the mounting piece, thereby ensuring that at least a part of the key column is always inside the mounting piece, and further ensuring that the key column is connected with the mounting piece.

[0025] Specifically, in the use process, the first elastic piece abuts between the locking piece and the moving piece. In this way, by abutting and limiting the third protrusion of the key column and the mounting piece, it can be ensured that the key column will not be separated from the mounting piece under the elastic force of the first elastic piece.

[0026] In some possible designs, the moving piece includes a claw sleeve, the side wall of the claw sleeve is provided with a first protrusion, the first protrusion is in sliding connection with the guide structure and can abut against the end of the guide structure, and the second inclined surface is arranged on the first protrusion.

[0027] In this design, the moving piece includes a claw sleeve. The side wall of the claw sleeve is provided with a first protrusion, the first protrusion is in sliding connection with the guide structure, and the first protrusion can abut against the end of the guide structure, thereby limiting the locking piece in the locked position.

[0028] Specifically, the key post is internally hollow, and at least part of the sliding claw sleeve can extend into the interior of the key post. In addition, the first inclined surface is arranged at the opening end of the key post, and the second inclined surface is arranged on the first protrusion. When the pressing piece is pressed for the first time, the first protrusion drives the moving piece to move along the guide structure; when the moving piece moves to the end of the guide structure, the second inclined surface cooperates with the first inclined surface to drive the moving piece to rotate, at this time, the first protrusion can abut against the limiting portion, and the locking piece is limited in the locked position. When the pressing piece is pressed for the second time, the second inclined surface cooperates with the first inclined surface to drive the moving piece to rotate again, at this time, the moving piece moves reversely along the guide structure under the action of the first elastic piece, and then the first protrusion is separated from the limiting portion, and the locking piece is switched from the locked position to the unlocked position.

[0029] In some possible designs, the moving piece is internally hollow, the side wall of the moving piece is provided with a guide groove, the extension direction of the guide groove is consistent with the movement direction of the locking piece; at least part of the locking piece is located in the moving piece, the side wall of the locking piece is provided with a second protrusion, and the second protrusion is in sliding connection with the guide groove.

[0030] In this design, the moving piece is internally hollow, and at least part of the locking piece is located in the interior of the moving piece. In addition, the side wall of the moving piece is provided with a guide groove, the extension direction of the guide groove is consistent with the movement direction of the locking piece; the locking piece is provided with a second protrusion, the second protrusion is located in the guide groove, and the second protrusion is in sliding connection with the guide groove. In this way, in the use process, the locking piece can move relative to the moving piece under the action of an external force, and then it is ensured that even if the user inadvertently closes the locking assembly, the locking piece can still retract into the mounting piece, so as to ensure that the locking piece can be connected and limited with the fixing piece.

[0031] Specifically, in the case that the door body assembly is opened, the first elastic piece abuts between the moving piece and the locking piece. At this time, the second protrusion is located in the middle of the guide groove or at the first end of the guide groove close to the bottom of the mounting piece, so as to ensure that the locking piece can retract into the interior of the mounting piece under the action of an external force, and then it is ensured that even if the user inadvertently closes the locking assembly, the locking piece can still be locked with the fixing piece.

[0032] In addition, when the locking piece moves, the second protrusion moves along the guide groove, and then the second protrusion and the guide groove cooperate to play a certain limiting and guiding role, and then the running stability of the locking piece is improved.

[0033] In some possible designs, the locking piece further includes a driving inclined surface, and the fixing piece can abut against the driving inclined surface to drive the locking piece to move relative to the mounting piece.

[0034] In this design, the locking mechanism also includes a drive ramp. Specifically, if the user accidentally triggers the locking mechanism after the door assembly is opened, the locking mechanism will extend from its mounting bracket. At this point, the user can directly drive the door assembly to close without having to press the push button again, making it more convenient for the user.

[0035] Specifically, during the process of the user closing the door assembly, the fixing member first contacts the driving ramp of the locking member. The driving ramp decomposes the force exerted on the locking member by the fixing member into a horizontal component and a vertical component. The vertical component can be used to counteract the pushing force exerted on the locking member by the first elastic member, thereby causing the locking member to move under the action of the aforementioned vertical component, causing the locking member to retract into the mounting member. At this point, the user can close the door assembly.

[0036] In some possible designs, the locking assembly further includes: a second elastic member disposed within the mounting member and connected to the drive member and the mounting member for resetting the locking member; wherein at least a portion of the first elastic member is located inside the locking member, and the second elastic member is sleeved on the locking member.

[0037] In this design, the locking assembly also includes a second elastic element. This second elastic element is disposed within the mounting component and abuts against the moving part of the drive component and the cover plate of the mounting component. Thus, the cooperation between the first and second elastic elements further enhances the stability of the locking component.

[0038] Specifically, during the pressing process, before the pressing member comes into contact with the moving member, the pressing member will squeeze the second elastic member, at which time the second elastic member is in a compressed state; after the pressing member comes into contact with the moving member, the pressing member will squeeze the first elastic member and the second elastic member at the same time, at which time both the first elastic member and the second elastic member are in a compressed state.

[0039] Specifically, when the moving part is confined to the end of the guide structure, both the first and second elastic elements, which are in a compressed state, apply a thrust to the moving part, thereby stably confining it to the end of the guide structure. Upon pressing the pressing element again, the moving part rotates and disengages from the end of the guide structure; at this time, the first and second elastic elements, which are in a compressed state, cooperate to reset the moving part to its previous position. During this process, the cooperation of the first and second elastic elements significantly increases the thrust on the driving element, thereby further enhancing the stability of the locking element.

[0040] In some possible designs, the mounting components include: a fixed bracket; a first opening disposed on the fixed bracket, through which a drive member passes; a cover plate connected to the fixed bracket; and a second opening disposed on the cover plate, through which a locking member can pass.

[0041] In this design, the mounting components include a fixed bracket, a first opening, a cover plate, and a second opening. The fixed bracket ensures the stable installation of the entire locking assembly; the cover plate is connected to the fixed bracket, allowing the cover plate to cooperate with the fixed bracket to secure the locking element and the first elastic element, among other components.

[0042] In addition, the fixed bracket is provided with a first opening, and the cover plate is provided with a second opening, with the first opening and the second opening corresponding to each other. The pressing part of the locking member passes through the first opening and is located on the surface of the cooking appliance; the locking member can pass through the second opening under the drive of the moving member and the first elastic member, and extend into the fixing port of the fixing member to complete the limiting of the door assembly.

[0043] A second aspect of the present invention provides a cooking appliance, comprising: a cavity assembly; a door assembly that is openable and closable with the cavity assembly; and a locking structure as designed above; wherein the fixing member is disposed in one of the cavity assembly and the door assembly, and the locking assembly is disposed in the other of the cavity assembly and the door assembly.

[0044] The cooking appliance proposed in this invention includes a cavity assembly, a door assembly, and a locking structure of any of the above designs. The cavity assembly includes a cooking cavity for holding food to be cooked. The door assembly is connected to the cavity assembly and is used to open or close the cooking cavity. Specifically, the door assembly can be rotatably connected to the cavity assembly or slidably connected to it. One of the cavity assembly and the door assembly is provided with a fixing member, and the other is a locking component. The locking component cooperates with the fixing member to lock the door assembly onto the cavity assembly. Specifically, the locking component is a child lock and serves as an auxiliary connection.

[0045] When the door assembly is closed, the locking element is in the locked position; at this time, the connection between the locking element and the fixing element is limited, and the user cannot open the door assembly. Before opening the door assembly, the connection limit between the locking element and the fixing element is released; at this time, the locking element is in the unlocked position, and the locking element and the fixing element are separated.

[0046] During the opening of the door assembly, the door assembly can be directly driven to separate from the cavity assembly to complete the opening operation; at this time, the locking component remains in the unlocking position. During the closing of the door assembly, the door assembly can be directly closed and the locking component's position can be switched again, so that the locking component and the fixing component are connected and limited.

[0047] Furthermore, once the user switches the locking mechanism to the engaged position when the door assembly is open, the first elastic element abuts against the locking mechanism and the drive mechanism, creating an elastic connection between them. This ensures that the locking mechanism remains connected and limited by the fixing element during the door assembly's closing process, without requiring the user to switch the locking mechanism's position beforehand.

[0048] In some possible designs, the cavity assembly includes: a cavity body; and a cover enclosing at least a portion of the cavity body.

[0049] In this design, the cavity assembly includes a cavity body and a cover. The cavity body contains a cooking cavity for holding food to be cooked. The cover surrounds at least a portion of the cavity body, thus providing good protection for it. Furthermore, a mounting cavity exists between the cavity body and the cover, allowing relevant components of the cooking appliance to be installed within this cavity.

[0050] In some possible designs, the door assembly may also include: a door body; a door seal connected to the door body; and a latch, located on the door body or door seal, for opening and closing connection with the cavity assembly.

[0051] In this design, the door assembly includes a door body, a door seal, and a latch. The door body is connected to the cavity assembly for opening and closing, and can be used to open or close the cooking cavity. The door seal is connected to the door body and provides a good seal when the door body closes the cooking cavity, ensuring a good seal during operation. Furthermore, the latch is located on either the door body or the door seal and is connected to the cavity assembly for opening and closing. When the door body closes the cooking cavity, the latch connects to the cavity assembly to ensure the connection between the door assembly and the cavity assembly.

[0052] Specifically, the door assembly of the cooking appliance proposed in this invention includes a latch, which is used to connect with the cavity assembly, thereby ensuring a stable connection between the door assembly and the cavity assembly. That is, the cooking appliance proposed in this invention first ensures the connection between the door assembly and the cavity assembly through the latch, and then the locking assembly can be used as a child lock, allowing the locking assembly to cooperate with the fixing member to further restrict the user from opening the door assembly.

[0053] In some possible designs, the locking assembly is located within the cavity assembly, and the mounting element is connected to the cavity body.

[0054] In this design, the locking assembly can be located within the cavity assembly. When the locking assembly is located within the cavity assembly, its mounting component can be connected to the cavity body. In this case, the fixing component is located within the door assembly, ensuring that the locking assembly and the fixing component are positioned correspondingly. Specifically, the mounting component and the cavity body can be connected using fasteners such as screws, or they can be engaged using snap-fit ​​connections.

[0055] In addition, the cavity body itself has good strength and hardness. Connecting the mounting part of the locking component to the cavity body can further ensure the connection of the locking component, improve the stability of the fit between the locking component and the fixing part, and extend the service life of the locking component and the entire cooking appliance.

[0056] Specifically, the cavity body includes an end plate, which is the front panel of the cavity assembly, and the mounting component is connected to the end plate of the cavity body.

[0057] In some possible designs, the locking assembly is located within the cavity assembly, and the mounting element is connected to the housing.

[0058] In this design, the locking component can be located within the cavity assembly. When the locking component is located within the cavity assembly, its mounting part can be connected to the cover. In this case, the fixing part is located within the door assembly, thus ensuring that the locking component and the fixing part are positioned correspondingly. Specifically, the mounting part and the cover can be connected using fasteners such as screws, or they can be engaged using snap-fit ​​connections.

[0059] Furthermore, the cover's structure is relatively simple, and the locking assembly's mounting parts are connected to the cover, reducing the difficulty of installing the locking assembly and thus improving the assembly efficiency of the locking assembly and cooking utensils. Moreover, the connection between the locking assembly's mounting parts and the cover reduces the structural and manufacturing requirements of the cavity body, further improving the manufacturing efficiency of the cavity body.

[0060] Specifically, the housing includes a top plate, a first side plate, and a second side plate. The first side plate is connected to a first side of the top plate, and the second side plate is connected to a second side of the top plate. A mounting component for the locking assembly is connected to the top plate and located between the first and second side plates. This positions the locking assembly at the top of the cavity body and ensures the embedded installation of the mounting component.

[0061] In some possible designs, fasteners are installed on the door assembly and connected to the door body.

[0062] In this design, the fastener can be installed in the door assembly. When the fastener is installed in the door assembly, it can be connected to the door body. In this case, the locking assembly is installed in the cavity assembly, thus ensuring that the locking assembly and the fastener are positioned correspondingly. Specifically, the fastener and the door body can be connected using fasteners such as screws, or they can be engaged using snap-fit ​​connections.

[0063] In addition, the door body itself has good strength and hardness. Connecting the fastener to the door body can further ensure the connection of the fastener, improve the stability of the cooperation between the locking component and the fastener, and extend the service life of the fastener and the entire cooking appliance.

[0064] In some possible designs, the fastener is installed on the door assembly and connected to the door seal.

[0065] In this design, the fastener can be installed in the door assembly. When the fastener is installed in the door assembly, it can be connected to the door seal. In this case, the locking assembly is installed in the cavity assembly, thus ensuring that the locking assembly and the fastener are positioned correspondingly. Specifically, the fastener and the door seal can be connected using fasteners such as screws, or they can be engaged using snap-fit ​​connections.

[0066] Furthermore, during the use of the cooking appliance, the door seal comes into direct contact with the cavity assembly and is closer to the cavity assembly than the door body. Therefore, installing the fastener on the door seal reduces the size requirements of the fastener and simplifies the structure of the fastener and the entire cooking appliance.

[0067] In some possible designs, the fastener is installed on the door assembly, and the fastener and the door body are an integral structure.

[0068] In this design, the fastener can be installed in the door assembly. When the fastener is installed in the door assembly, it can be an integral part of the door body. Specifically, this integral structure reduces the need for connecting parts between the fastener and the door body, and significantly improves the connection strength between them. This ensures the stability of the connection between the fastener and the locking mechanism, thereby extending the lifespan of both the fastener and the entire cooking appliance.

[0069] In some possible designs, the fastener is installed on the door assembly, and the fastener and door seal are an integrated structure.

[0071] In some possible designs, a fastener is installed on the cavity assembly, and the fastener is connected to the cavity body.

Connecting the fixing part to the cavity body can further ensure the connection of the fixing part, improve the stability of the cooperation between the locking component and the fixing part, and extend the service life of the fixing part and the entire cooking appliance.

[0074] In some possible designs, the fastener is positioned on the cavity assembly and connected to the cover.

[0076] Furthermore, the cover's structure is relatively simple, and the fasteners are connected to the cover, reducing the difficulty of installing the fasteners and thus improving the assembly efficiency of the locking components and cooking utensils. Moreover, the connection between the fasteners and the cover reduces the structural and manufacturing requirements of the cavity body, further improving the manufacturing efficiency of the cavity body.

[0077] Specifically, the cover includes a top plate, a first side plate, and a second side plate; the first side plate is connected to a first side of the top plate, and the second side plate is connected to a second side of the top plate. A fastener is connected to the top plate and is located between the first and second side plates. This positions the fastener at the top of the cavity body.

[0080] In addition, the door body itself has good strength and hardness. The mounting parts of the locking component are connected to the door body, which can further ensure the connection of the locking component and improve the stability of the cooperation between the locking component and the fixing parts, so as to extend the service life of the locking component and the entire cooking appliance.

Detailed Implementation

[0119] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0120] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0121] The following reference Figures 1 to 25 To describe the lock structure and cooking appliance 100 provided according to some embodiments of the present invention.

[0122] like Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the first embodiment of the present invention proposes a lock structure, including a fixing member 106 and a locking assembly 108. The locking assembly 108 and the fixing member 106 can be used together to achieve a locking and limiting function. Specifically, as shown... Figure 1 and Figure 2 As shown, the lock structure proposed in this invention can be applied to cooking appliance 100 and used as a child lock for cooking appliance 100.

[0123] In particular, such as Figure 7 , Figure 8 and Figure 12 As shown, the locking assembly 108 includes a mounting member 110, a driving member 112, a first elastic member 114, and a locking member 116. The mounting member 110 is attached to an external object (e.g., the door assembly 104 or cavity assembly 102 of the cooking appliance 100); such as... Figure 7 and Figure 12As shown, at least a portion of the driving member 112 is disposed within the mounting member 110, and a first end of the first elastic member 114 is connected to the driving member 112; a second end of the first elastic member 114 is connected to the locking member 116. Thus, the driving member 112 can apply a thrust to the locking member 116 via the first elastic member 114, causing the locking member 116 to move relative to the mounting member 110 under the drive of the driving member 112 and the first elastic member 114, thereby causing the locking member 116 to pass through the mounting member 110 and lock with the fixing member 106.

[0124] In particular, in the lock structure proposed in this invention, such as Figure 7 and Figure 12 As shown, the first elastic member 114 abuts against the driving member 112 and the locking member 116, thereby realizing a flexible connection between the locking member 116 and the driving member 112. In this way, when the locking assembly 108 is in the locked position, the presence of the first elastic member 114 allows the locking member 116 to still move toward the driving member 112.

[0125] Specifically, such as Figure 7 and Figure 12 As shown, the fixing member 106 and the locking component 108 can be respectively installed on the door component 104 of the cavity component 102. Therefore, when the door component 104 is open, if the user accidentally closes the locking component 108, the fixing member 106 will come into contact with the locking component 116 during the process of the user closing the door component 104 without switching the position of the locking component 116, thereby forcing the locking component 116 to move toward the driving member 112.

[0126] In this way, on the one hand, the locking member 116 and the fixing member 106 can be connected and limited, and on the other hand, the connection and limitation of the locking member 116 and the fixing member 106 do not require user operation, which greatly improves the ease of use of the locking component 108.

[0127] like Figure 1 As shown, when the door assembly 104 is in the closed state, the locking member 116 is in the locked position; at this time, the locking member 116 is limited in connection with the fixing member 106, and the user cannot open the door assembly 104. Before opening the door assembly 104, the connection limitation between the locking member and the fixing member 106 is released; at this time, the locking member 116 is in the unlocked position, and the locking member 116 is separated from the fixing member 106.

[0128] like Figure 2As shown, during the opening of the door assembly 104, the door assembly 104 can be directly driven to separate from the cavity assembly 102 to complete the opening operation; at this time, the locking member 116 is still in the unlocking position. During the closing of the door assembly 104, the door assembly 104 can be closed directly and the position of the locking member 116 can be switched again so that the locking member 116 and the fixing member 106 are locked and limited.

[0129] And, as Figure 7 and Figure 12 As shown, when the door assembly 104 is open, once the user switches the locking member 116 to the locked position, the first elastic member 114 abuts against the locking member 116 and the driving member 112, making the locking member 116 and the driving member 112 elastically connected. In this way, the user does not need to switch the position of the locking member 116 in advance, which can ensure that the locking member 116 can still be locked and limited with the fixing member 106 during the closing process of the door assembly 104.

[0130] Specifically, the locking structure proposed in this invention can be applied to a cooking appliance 100. After the cooking process in the cooking appliance 100 is completed, the food inside the cooking cavity is at a high temperature. If the user directly opens the door to remove the food, there is a risk of burns. Therefore, this invention, through the cooperation of the locking component 108 and the fixing member 106, ensures that if the user wants to open the door component 104, they must simultaneously pull out the locking member 116. This serves as a reminder to the user and prevents children from accidentally opening the door component 104, greatly improving the safety of using the cooking appliance 100.

[0131] Therefore, the lock structure proposed in this invention, through the cooperation of the locking component 108 and the fixing member 106, increases the difficulty of unlocking the lock structure, preventing users, especially children, from accidentally opening the door component 104, and improving the safety of using the cooking appliance 100 with this lock structure. Furthermore, the flexible connection between the driving member 112 and the locking member 116 allows the door component 104 to be closed without driving the locking member 116, even if the user accidentally switches the locking member 116 to the locked position when the door component 104 is open, ensuring the connection limit between the locking member 116 and the fixing member 106.

[0132] The second embodiment of the present invention proposes a lock structure, which, based on the first embodiment, further includes:

[0133] like Figure 7 and Figure 15As shown, the locking assembly 108 also includes a guide structure 118. The guide structure 118 is disposed inside the mounting member 110, and at least a portion of the driving member 112 is slidably connected to the guide structure 118 and can be limited at the end of the guide structure 118, thereby causing the locking member 116 to remain in the locking position.

[0134] Specifically, a limiting portion is provided at the end of the guide structure 118, and at least a portion of the drive member 112 can move along the guide structure 118; when at least a portion of the drive member 112 moves to the end of the guide structure 118, at least a portion of the drive member 112 abuts against the limiting portion at the end of the guide structure 118, thereby limiting the locking member 116 to the locked position.

[0135] Specifically, such as Figure 15 As shown, the guide structure 118 includes a guide rib, the extension direction of which is consistent with the movement direction of the locking member 116; at least a portion of the driving member 112 can move along the guide rib, and at least a portion of the driving member 112 can abut against the end of the guide rib, thereby limiting the locking member 116 to the locked position.

[0136] The third embodiment of the present invention proposes a lock structure, which, based on the second embodiment, further includes:

[0137] like Figure 7 , Figure 13 and Figure 14 As shown, the driving member 112 includes a pressing member 120 and a moving member 122. The pressing member 120 is movably connected to and passes through the mounting member 110; at least a portion of the pressing member 120 is located on the outer surface of the entire cooking appliance 100. During use of the cooking appliance 100, the position of the locking member 116 can be switched by pressing the pressing member 120. The moving member 122 is disposed inside the mounting member 110 and is slidably connected to the guide structure 118.

[0138] Furthermore, the moving part 122 is connected to the first end of the first elastic member 114, such that the first elastic member 114 is located between the moving part 122 and the locking member 116. Therefore, during the use of the cooking appliance 100, the user can press the pressing member 120, which drives the moving part 122 to move. The moving part 122 drives the locking member 116 to switch positions through the first elastic member 114.

[0139] Specifically, such as Figure 12 , Figure 13 and Figure 14 As shown, the pressing member 120 includes a first inclined surface 124, and the moving member 122 includes a second inclined surface 126. When the user presses the pressing member 120, the first inclined surface 124 of the pressing member 120 comes into contact with the second inclined surface 126 of the moving member 122.

[0140] like Figure 12 As shown, when the pressing member 120 is pressed for the first time, the moving member 122 will move along the guide structure 118; when the moving member 122 moves to the end of the guide structure 118, the second inclined surface 126 cooperates with the first inclined surface 124 to drive the moving member 122 to rotate. At this time, the moving member 122 can abut against the limiting part, and the locking member 116 is limited to the locked position.

[0141] like Figure 12 As shown, when the pressing member 120 is pressed for the second time, the second inclined surface 126 cooperates with the first inclined surface 124 to drive the moving member 122 to rotate again. At this time, the moving member 122 will move in the opposite direction along the guide structure 118, thereby causing the moving member 122 to separate from the limiting part, and the locking member 116 will switch from the locked position to the unlocked position.

[0142] The fourth embodiment of the present invention proposes a lock structure, which, based on the third embodiment, further includes:

[0143] like Figure 12 and Figure 13 As shown, the pressing member 120 includes a button post. The side wall of the button post is provided with a third protrusion 166 that can abut against the end of the mounting member 110, thereby ensuring that at least a portion of the mounting post is always inside the mounting member 110, and thus ensuring that the button post is connected to the mounting member 110.

[0144] Specifically, during use, the first elastic element abuts between the locking element and the moving element. Thus, by the third protrusion 166 abutting against and limiting the mounting part, it can be ensured that the button post will not detach from the mounting part under the elastic force of the first elastic element.

[0145] like Figure 12 and Figure 14 As shown, the moving part 122 includes a sliding pawl sleeve. The side wall of the sliding pawl sleeve is provided with a first protrusion 128, which is slidably connected to the guide structure 118, and the first protrusion 128 can abut against the end of the guide structure 118, thereby limiting the locking part 116 to the locked position.

[0146] Specifically, such as Figure 12 and Figure 14 As shown, the button post is hollow inside, and at least a portion of the sliding claw sleeve can extend into the interior of the button post. Furthermore, a first inclined surface 124 is provided at the open end of the button post, and a second inclined surface 126 is provided at the first protrusion.

[0147] When the pressing member 120 is pressed for the first time, the first protrusion 128 drives the moving member 122 to move along the guide structure 118; when the moving member 122 moves to the end of the guide structure 118, the second inclined surface 126 cooperates with the first inclined surface 124 to drive the moving member 122 to rotate. At this time, the first protrusion 128 can abut against the limiting part, and the locking member 116 is limited to the locked position.

[0148] When the pressing member 120 is pressed for the second time, the second inclined surface 126 cooperates with the first inclined surface 124 to drive the moving member 122 to rotate again. At this time, the moving member 122 will move in the opposite direction along the guide structure 118 under the action of the first elastic member 114, thereby causing the moving member 122 to separate from the limiting part, and the first protrusion 128 to switch from the locked position to the unlocked position.

[0149] In specific embodiments, such as Figure 13 and Figure 14 As shown, the first inclined surface 124 can be a serrated inclined surface on the key post, and the second inclined surface 126 can be a serrated inclined surface on the moving part. Furthermore, the first inclined surface 124 and the second inclined surface 126 defined in this invention are not limited to the aforementioned serrated inclined surface; any inclined surface that can cooperate with the driving locking part to rotate and move is acceptable, as will be understood by those skilled in the art.

[0150] In this embodiment, the moving member 122 is hollow inside, and at least a portion of the locking member 116 is located inside the moving member 122. Furthermore, the sidewall of the moving member 122 is provided with a guide groove 170, the extending direction of which is consistent with the movement direction of the locking member 116; the locking member 116 is provided with a second protrusion 130, the second protrusion 130 being located within the guide groove 170, and the second protrusion 130 being slidably connected to the guide groove 170.

[0151] In this way, during use, the locking member 116 can move relative to the moving member 122 under the action of external force, thereby ensuring that even if the user accidentally closes the locking component 108, the locking member 116 can still retract into the mounting member 110, so as to ensure that the locking member 116 and the fixing member 106 can be connected and limited.

[0152] Specifically, when the door assembly 104 is open, the first elastic member 114 abuts against the moving member 122 and the locking member 116. At this time, the second protrusion 130 is located in the middle of the guide groove 170 or at the first end of the guide groove 170 near the bottom of the mounting member 110, so as to ensure that the locking member 116 can retract into the mounting member 110 under external force, thereby ensuring that even if the user accidentally closes the locking assembly 108, the locking member 116 can still be locked with the fixing member 106.

[0153] In addition, when the locking member 116 moves, the second protrusion 130 moves along the guide groove 170, and the cooperation between the second protrusion 130 and the guide groove 170 plays a certain role in limiting and guiding, thereby improving the smoothness and stability of the operation of the locking member 116.

[0154] The fifth embodiment of the present invention proposes a lock structure, which, based on the first embodiment, further includes:

[0155] like Figure 7 As shown, the locking element 116 also includes a driving ramp 132. When the door assembly 104 is opened, if the user accidentally triggers the locking element 108, the locking element 116 will extend the mounting part 110. At this time, when the user is closing the door assembly 104, they can directly drive the door assembly 104 to close without having to press the pressing part 120 again, making it more convenient for the user.

[0156] Specifically, during the process of the user closing the door assembly 104, the fixing member 106 first contacts the driving ramp 132 of the locking member 116. The driving ramp 132 decomposes the force applied to the locking member 116 by the fixing member 106 into a horizontal component and a vertical component. The vertical component can be used to counteract the pushing force applied to the locking member 116 by the first elastic member 114, thereby causing the locking member 116 to move under the action of the aforementioned vertical component, so that the locking member 116 retracts into the mounting member 110. At this time, the user can close the door assembly 104.

[0157] The sixth embodiment of the present invention proposes a lock structure, which, based on the first embodiment, further includes:

[0158] like Figure 7 and Figure 12 As shown, the locking assembly 108 also includes a second elastic member 134. The second elastic member 134 is disposed within the mounting member 110 and abuts against the moving part 122 of the driving member 112 and the cover plate 140 of the mounting member 110. Thus, the cooperation between the first elastic member 114 and the second elastic member 134 further enhances the stability of the locking member 116.

[0159] Specifically, during the pressing of the pressing member 120, before the pressing member 120 contacts the moving member 122, the pressing member 120 will squeeze the second elastic member 134, at which time the second elastic member 134 is in a compressed state; after the pressing member 120 contacts the moving member 122, the pressing member 120 will simultaneously squeeze the first elastic member 114 and the second elastic member 134, at which time both the first elastic member 114 and the second elastic member 134 are in a compressed state.

[0160] like Figure 7 and Figure 12As shown, when the moving member 122 is positioned at the end of the guide structure 118, both the first elastic member 114 and the second elastic member 134, which are in a compressed state, apply a thrust to the moving member 122, thereby stably limiting the moving member 122 to the end of the guide structure 118. After pressing the pressing member 120 again, the moving member 122 rotates and disengages from the end of the guide structure 118; at this time, the first elastic member 114 and the second elastic member 134, which are in a compressed state, cooperate to reset the moving member 122 to its previous position. In this process, due to the cooperation of the first elastic member 114 and the second elastic member 134, the thrust on the driving member 112 is greatly increased, thereby further improving the stability of the locking member 116.

[0161] The seventh embodiment of the present invention proposes a lock structure, which, based on the first embodiment, further includes:

[0162] like Figure 7 , Figure 12 and Figure 15 As shown, the mounting component 110 includes a fixed bracket 136, a first opening 138, a cover plate 140, and a second opening 142. The fixed bracket 136 ensures the stable installation of the entire locking assembly 108; the cover plate 140 is connected to the fixed bracket 136, so that the cover plate 140 cooperates with the fixed bracket 136 to ensure the installation of components such as the locking member 116 and the first elastic member 114.

[0163] In addition, such as Figure 11 As shown, the fixed bracket 136 is provided with a first opening 138, and the cover plate 140 is provided with a second opening 142, with the first opening 138 and the second opening 142 corresponding to each other. The pressing part of the locking member 116 passes through the first opening 138 and is located on the surface of the cooking appliance 100; the locking member 116 can pass through the second opening 142 under the drive of the moving member 122 and the first elastic member 114, and extend into the fixing port 164 of the fixing member 106 to complete the limiting of the door assembly 104.

[0164] In specific embodiments, such as Figure 8 , Figure 9 and Figure 10 As shown, the fixed bracket 136 includes a card interface, and the cover plate 140 includes a card engaging portion, which is engaged within the card interface to achieve the connection between the cover plate 140 and the fixed bracket 136.

[0165] like Figure 1 and Figure 2 As shown, the eighth embodiment of the present invention provides a cooking appliance 100, including a cavity assembly 102, a door assembly 104, and a lock structure of any of the above embodiments. Therefore, all the beneficial effects of the lock structure of any of the above embodiments will not be discussed in detail here.

[0166] In addition, such as Figure 1 and Figure 2 As shown, the cavity assembly 102 includes a cooking cavity for placing food to be cooked; the door assembly 104 is connected to the cavity assembly 102 for opening or closing the cooking cavity.

[0167] Specifically, the door assembly 104 can be rotatably connected to the cavity assembly 102, or it can be slidably connected to the cavity assembly 102. One of the cavity assembly 102 and the door assembly 104 is provided with a fixing member 106, and the other of the cavity assembly 102 and the door assembly 104 is provided with a locking assembly 108. The locking assembly 108 cooperates with the fixing member 106 to lock the door assembly 104 onto the cavity assembly 102. Specifically, the locking assembly 108 is a child lock and also serves as an auxiliary connection.

[0168] like Figure 1 As shown, when the door assembly 104 is in the closed state, the locking member 116 is in the locked position; at this time, the locking member 116 is limited in connection with the fixing member 106, and the user cannot open the door assembly 104. Before opening the door assembly 104, the connection limitation between the locking member and the fixing member 106 is released; at this time, the locking member 116 is in the unlocked position, and the locking member 116 is separated from the fixing member 106.

[0169] like Figure 2 As shown, during the opening of the door assembly 104, the door assembly 104 can be directly driven to separate from the cavity assembly 102 to complete the opening operation; at this time, the locking member 116 is still in the unlocking position. During the closing of the door assembly 104, the door assembly 104 can be closed directly and the position of the locking member 116 can be switched again so that the locking member 116 is connected and limited to the fixing member 106.

[0170] Furthermore, when the door assembly 104 is open, once the user switches the locking member 116 to the locked position, the first elastic member 114 abuts against the locking member 116 and the driving member 112, creating an elastic connection between them. This ensures that the user does not need to switch the locking member 116's position beforehand, guaranteeing that the locking member 116 remains connected and limited by the fixing member 106 during the closing process of the door assembly 104.

[0171] The ninth embodiment of the present invention proposes a lock structure, which, based on the eighth embodiment, further includes:

[0172] like Figure 2 and Figure 20As shown, the cavity assembly 102 includes a cavity body 144 and a cover 146. The cavity body 144 contains a cooking cavity for holding food to be cooked. The cover 146 surrounds at least a portion of the cavity body 144, thus providing good protection for the cavity body 144. Furthermore, a mounting cavity exists between the cavity body 144 and the cover 146, allowing relevant components of the cooking appliance 100 to be installed within this mounting cavity.

[0173] In this embodiment, further, as Figure 6 and Figure 23 As shown, the door assembly 104 includes a door body 148, a door seal 150, and a latch 152. The door body 148 is connected to the cavity assembly 102 for opening and closing, and can be used to open or close the cooking cavity. The door seal 150 is connected to the door body 148 and provides a good seal when the door body 148 closes the cooking cavity, ensuring a good sealing effect during operation. Furthermore, the latch 152 is connected to either the door body 148 or the door seal 150. When the door body 148 closes the cooking cavity, the latch 152 is connected to the cavity assembly 102 to ensure the connection between the door assembly 104 and the cavity assembly 102.

[0174] Therefore, the door assembly 104 of the cooking appliance 100 proposed in this invention includes a latch 152, which is used to connect with the cavity assembly 102, thereby ensuring a stable connection between the door assembly 104 and the cavity assembly 102. That is, the cooking appliance 100 proposed in this invention can first ensure the connection between the door assembly 104 and the cavity assembly 102 through the latch 152, and then the locking assembly 108 can be used as a child lock, so that the locking assembly 108 cooperates with the fixing member 106 to further restrict the user from opening the door assembly 104.

[0175] The tenth embodiment of the present invention proposes a lock structure, which, based on the ninth embodiment, further includes:

[0176] like Figure 23 and Figure 25 As shown, the mounting part 110 of the locking assembly 108 is connected to the cavity body 144, and the fixing part 106 is connected to the door body 148.

[0177] Among them, such as Figure 25 As shown, the mounting part 110 of the locking assembly 108 is connected to the cavity body 144. In particular, the cavity body 144 itself has good strength and hardness. Connecting the mounting part 110 of the locking assembly 108 to the cavity body 144 can further ensure the connection firmness of the locking assembly 108, improve the cooperation stability between the locking assembly 108 and the fixing part 106, and extend the service life of the locking assembly 108 and the entire cooking appliance 100.

[0178] Specifically, the mounting component 110 and the cavity body 144 can be connected by fasteners 162 such as screws, or by snap-fit ​​connections.

[0179] In addition, such as Figure 23 As shown, the fastener 106 is connected to the door body 148. In addition, the door body 148 itself has good strength and hardness. Connecting the fastener 106 to the door body 148 can further ensure the connection firmness of the fastener 106, improve the cooperation stability between the locking assembly 108 and the fastener 106, and extend the service life of the fastener 106 and the entire cooking appliance 100.

[0180] Specifically, the fastener 106 and the door body 148 can be connected by fasteners such as screws 162, or by snap-fit.

[0184] Among them, such as Figure 25 As shown, the mounting part 110 of the locking assembly 108 is connected to the cavity body 144. In particular, the cavity body 144 itself has good strength and hardness. Connecting the mounting part 110 of the locking assembly 108 to the cavity body 144 can further ensure the connection firmness of the locking assembly 108, improve the cooperation stability between the locking assembly 108 and the fixing part 106, and extend the service life of the locking assembly 108 and the entire cooking appliance 100.

[0185] Specifically, the mounting component 110 and the cavity body 144 can be connected by fasteners 162 such as screws, or by snap-fit ​​connections.

[0186] In addition, such as Figure 22 As shown, the fastener 106 is connected to the door seal 150. During use of the cooking appliance 100, the door seal 150 is in direct contact with the cavity assembly 102 and is closer to the cavity assembly 102 than the door body 148. Therefore, installing the fastener 106 on the door seal 150 reduces the size requirements of the fastener 106 and simplifies the structure of the fastener 106 and the entire cooking appliance 100.

[0187] Specifically, the fastener 106 and the door body 148 can be connected by fasteners such as screws 162, or by snap-fit.

[0193] Furthermore, the fastener 106 and the door body 148 are an integral structure. In particular, the integral structure of the fastener 106 and the door body 148 reduces the number of connecting parts used between the fastener 106 and the door body 148, and greatly improves the connection strength between the fastener 106 and the door body 148, thereby ensuring the connection stability between the fastener 106 and the locking member 116, and extending the service life of the fastener 106 and the entire cooking appliance 100.

[0198] Specifically, the mounting component 110 and the cavity body 144 can be connected by fasteners 162 such as screws, or by snap-fit ​​connections.

[0199] In addition, such as Figure 21 As shown, the fastener 106 and the door seal 150 are an integral structure. In particular, the integral structure of the fastener 106 and the door seal 150 reduces the use of connecting parts between the fastener 106 and the door seal 150, and greatly improves the connection strength between the fastener 106 and the door seal 150, thereby ensuring the connection stability between the fastener 106 and the locking member 116, and extending the service life of the fastener 106 and the entire cooking appliance 100.

[0203] Among them, such as Figure 24 As shown, the mounting part 110 of the locking assembly 108 is connected to the cover 146. The structure of the cover 146 is relatively simple. The connection between the mounting part 110 of the locking assembly 108 and the cover 146 reduces the installation difficulty of the locking assembly 108, thereby improving the assembly efficiency of the locking assembly 108 and the cooking appliance 100. Furthermore, the connection between the mounting part 110 of the locking assembly 108 and the cover 146 reduces the structural and manufacturing requirements of the cavity body 144, further improving the manufacturing efficiency of the cavity body 144.

[0204] Specifically, the mounting component 110 and the cover 146 can be connected by fasteners 162 such as screws, or by snap-fit.

[0205] In addition, such as Figure 23 As shown, the fastener 106 is connected to the door body 148. The door body 148 itself has good strength and hardness.

In particular, the integrated structure of the mounting member 110 and the door seal 150 reduces the need for connecting parts between the mounting member 110 and the door seal 150, and greatly improves the connection strength between the mounting member 110 and the door seal 150, thereby ensuring the connection stability between the fixing member 106 and the locking member 116, and extending the service life of the locking assembly 108 and the entire cooking appliance 100.

[0271] Based on any of the above embodiments, further, such as Figure 1 and Figure 2 As shown, the cooking appliance 100 proposed in this invention includes, but is not limited to: microwave oven, oven, steam oven, or steam oven combination appliance.

[0272] Based on any of the above embodiments, further, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the locking component 108 is a child lock.

[0273] Based on any of the above embodiments, further, such as Figure 7 and Figure 12 As shown, in the cooking utensil 100 proposed in this invention, the first elastic member 114 includes a spring; the second elastic member 134 includes a spring; the locking member 116 includes a latch; and the fixing member 106 includes a locking pin, with a fixing opening 164 provided in the middle of the locking pin.

[0274] Based on any of the above embodiments, further, such as Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 22 As shown, when the locking assembly 108 is installed in the cover 146, the shape of the mounting part 110 of the locking assembly 108 is more flexible and varied.

[0275] Based on any of the above embodiments, further, such as Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, when the locking component 108 is installed on the door body 148, the mounting part 110 of the locking component 108 needs to have a certain protrusion to ensure that the mounting part 110 can be connected to the door body 148, so as to avoid the installation of the locking component 108 being affected by the excessive thickness of the door body 148.

[0276] After cooking, the user can directly open the door assembly 104 of the cooking appliance 100. However, the freshly cooked food is often very hot, posing a risk of burns. This is especially true when children use the cooking appliance 100 to cook food, increasing the risk of accidents.

[0277] Based on any of the above embodiments, further, such as Figure 4 As shown, when the locking component 108 is installed in the cavity component 102 and the fixing component 106 is installed in the door component 104, the end plate 154 of the cavity component 102 is provided with an insertion port 168, and the fixing component 106 can extend into the insertion port 168 to ensure that the fixing component 106 and the locking component 116 are locked together.

[0278] In related technologies, a button-type lock structure is used to restrict the opening and closing of door components. However, when the door components are open, there is a possibility that the user may accidentally trigger the button-type structure. In this case, the user will not be able to close the button-type lock structure, thus preventing the user from closing the door components.

[0279] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cooking appliance 100 proposed in this invention adds a locking structure. Before the action of pressing or pulling the door can be completed, the connection limit between the locking component 108 and the fixing member 106 must be released before the entire door opening action can be completed.

[0280] In the cooking appliance 100 proposed in this invention, the press-type locking component 108 cooperates with the fixing member 106. This press-type locking component 108 can effectively prevent the door component 104 from being accidentally touched after the door component 104 is opened, thus preventing the door component 104 from being unable to be closed.

[0281] Specifically, such as Figure 12 As shown, the locking assembly 108 includes a pressing member 120, a moving member 122, a locking member 116, a latch, a fixed bracket 136 with a guide structure 118, a first elastic member 114, a second elastic member 134, and a cover plate 140. The fixed bracket 136 is then fixed to the external structure with screws. When the door assembly 104 is in the closed state, pressing the pressing member 120 causes the locking member 116 to extend downwards into the fixing port 164 of the fixed member 106. Simply pulling the handle of the door assembly 104 or simply pressing the door opening button of the door assembly 104 will not open the door.

[0282] When the pressing member 120 is pressed for the first time, it pushes the moving member 122 to compress the first elastic member 114 and the second elastic member 134. Simultaneously, the moving member 122 moves along the guide structure 118 to the critical point at the tip of the bottom of the guide structure 118. Then, the moving member 122 rotates to the right and is locked at the end of the fixed guide structure 118. During this process, the lower locking member 116 is subjected to the elastic force of the compressed first elastic member and moves downwards along the guide structure 118 until it reaches the lowest point of the guide structure 118. At this point, the locking member 116 enters the fixing port 164 of the fixing member 106, thus completing the locking action of the lock structure.

[0283] When the pressing member 120 is pressed for the second time, the pressing member 120 pushes the moving member 122 to the critical point position of the tip of the guide structure 118 of the fixed bracket 136. The moving member 122 will then return to the guide structure 118 and move back to the top along the guide structure 118 due to the spring force provided by the first elastic member 114 and the second elastic member 134. At this time, the locking member 116 will also leave the fixing port 164 of the fixing member 106, thus completing the locking action of the lock structure.

[0284] Furthermore, the locking and unlocking actions of the lock structure are achieved by pressing the pressing member 120, causing the locking member 116 to enter or leave the fixing slot 164 of the fixing member 106. For the door assembly 104 to close, the lock structure must be in the unlocked state.

[0285] Furthermore, such as Figure 1 As shown, when the door assembly 104 is in the open state, and there is a simultaneous accidental press of the pressing member 120 causing the locking assembly 108 to be locked, during the subsequent closing process of the door assembly 104, the inclined surface of the fixing member 106 will begin to act on the driving inclined surface 132 of the locking member 116 with a vertical inclined force, which can be decomposed into vertical and horizontal forces. The vertical force can be further decomposed to give the locking member 116 an upward force, thereby allowing the locking member 116 to compress the first elastic member 114 and move upward. Figure 2 As shown, after the door assembly 104 is closed, the compressed first elastic element 114 will act on the locking element 116, causing the locking assembly 108 to relock.

[0286] In specific embodiments, the locking assembly 108 and the fixing member 106 have multiple installation methods. Specifically, such as... Figure 24 As shown, the locking assembly 108 can be assembled to the outer cover of the cavity assembly 102 by means of screws or the like; Figure 25 As shown, the locking assembly 108 is also assembled to the end plate 154 of the cavity assembly 102 by means of screws or the like.

[0287] Specifically, such as Figure 21 As shown, the fastener 106 can be integrated with the door seal 150 of the door assembly 104; as Figure 22 As shown, the fastener 106 can also be a separate structure, assembled to the door seal 150 of the door assembly 104 by means of screws or the like; Figure 23 As shown, the fastener 106 can also be a separate structure and be assembled to the door body 148 of the door assembly 104 by means of screws or the like.
