Description

Technical Field

[0001] This invention belongs to the technical field of food processing equipment, and more specifically, relates to a lock structure and a cooking utensil. Background Technology

[0002] After cooking, users can directly open the door of the cooking appliance. However, the freshly cooked food is often still very hot, posing a risk of burns. This is especially true when children are using the cooking appliance, increasing the risk of accidents.

[0003] 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. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of the above, in a first aspect, the present invention provides a lock structure, comprising: a fixing member; and a locking assembly, the locking assembly comprising: a mounting member; a rotating member, at least a portion of which is disposed within the mounting member and is rotatable within the mounting member; a first elastic member, the second end of which is connected to the mounting member; a locking member, connected to the first end of the first elastic member, the first end of which abuts against the rotating member; when the rotating member rotates to a first position, the first elastic member is in an elastic deformation state, and the second end of the locking member is locked to the fixing member; when the rotating member rotates to a second position, the first elastic member is in its original state, and the second end of the locking member is separated from the fixing member; and a driving member, disposed on the mounting member, the driving member being used to drive the rotating member to move from the second position to the first position.

[0006] The lock structure provided by this invention includes a fixing member and a locking assembly. The locking assembly and the fixing member can be used together to achieve a locking and limiting function. Specifically, the lock structure proposed in this invention can be applied to cooking utensils and used as a child lock for cooking utensils.

[0007] Specifically, the locking assembly includes a mounting member, a rotating member, a first elastic member, and a locking member. The mounting member is installed on an external object (e.g., a door assembly or cavity assembly of a cooking appliance); at least a portion of the rotating member is disposed within the mounting member; and the second end of the first elastic member is connected to the locking member, and the second end of the first elastic member is also connected to the mounting member. Thus, the rotating member can apply a pushing force to the locking member, causing the first elastic member to elastically deform. When the rotating member stops pushing the locking member, the first elastic member drives the locking member to move and reset. This allows the locking member to move relative to the mounting member under the drive of the rotating member and the first elastic member, thereby causing the locking member to pass through the mounting member and lock with or separate from the fixed member.

[0008] Specifically, in the lock structure proposed in this invention, the first elastic member abuts between the mounting member and the locking member, thereby achieving a flexible connection between the locking member and the mounting member. Thus, even when the locking assembly is in the locked position, the presence of the first elastic member allows the locking member to still move towards the rotating member.

[0009] Specifically, the fixing component and the locking assembly can be installed on the cavity assembly and the door assembly respectively. Therefore, when the door assembly is open, if the user accidentally closes the locking assembly, the fixing component will come into contact with the locking component during the closing process without switching the locking component's position, thus forcing the locking component to move towards the rotating component. In this way, on the one hand, it can ensure that the locking component and the fixing component can be connected and limited, and on the other hand, the connection and limitation of the locking component and the fixing component do not require user operation, greatly improving the ease of use of the locking assembly.

[0010] 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 is separated from the fixing element.

[0011] When the door assembly is opened, once the user switches the locking mechanism to the engaged position, the first elastic element abuts against the locking mechanism and the mounting component, creating a flexible connection between them. This ensures that the locking mechanism remains engaged and limited by the fixing component even when the door assembly is closed, without requiring the user to switch the locking mechanism's position beforehand.

[0012] Specifically, the locking structure proposed in this invention can be applied to cooking appliances. After the cooking process is finished, the food inside the cooking cavity is still hot, and there is a risk of burns if the user directly opens the door to remove the food. Therefore, this invention, through the cooperation of the aforementioned locking component and fixing member, requires the user to pull the locking member while opening the door component. This serves as a reminder to the user and prevents children from accidentally opening the door component, greatly improving the safety of using the cooking appliance.

[0013] Therefore, the lock structure proposed in this invention increases the difficulty of unlocking the lock structure by cooperating with the locking component and the fixing component, preventing users, especially children, from accidentally opening the door component and improving the safety of cooking utensils using this lock structure. Furthermore, the flexible connection between the driving component and the locking component allows the door component to be closed without actuating the locking component, even if the user accidentally switches the locking component to the locked position when the door component is open, while maintaining the connection limit between the locking component and the fixing component.

[0014] The driving component can drive the rotating component to move from the second position to the first position. When the user stops pressing the rotating component, the driving component drives the rotating component to move to the first position, at which point the rotating component pushes the locking component to the locked position. By setting the driving component within the mounting component, it is ensured that the rotating component can automatically move to the first position.

[0015] In addition, the lock structure in the above-described technical solution provided by the present invention may also have the following additional technical features:

[0016] In one possible design, the locking element includes a first drive ramp, and the fixing element is capable of abutting against the first drive ramp to drive the locking element to move relative to the mounting element.

[0017] In this design, the locking element has a first driving ramp, which serves as a guide surface. Specifically, when the door assembly of the cooking appliance is open, the locking element is in the locked position. The user can move the locking element to the unlocked position by pressing the rotating component. However, because the locking element has the first driving ramp, when the user wants to close the door assembly, the first driving ramp can contact the fixing component. The pushing force of the fixing component on the locking element has a component force that pushes the locking element towards the rotating component, thus allowing the locking element to move towards the rotating component and disengage from the locked position. When the door assembly moves to the closed position, the fixing component no longer pushes the locking element. At this time, under the elastic force of the first elastic component, the locking element moves to the position where it locks with the fixing component. By providing a first driving ramp on the locking element, during the process of closing the door assembly, the user does not need to actively switch the locking element to the unlocked position; the locking element can automatically switch positions, simplifying the user's operation and further improving the user's convenience in using the locking element.

[0018] In one possible design, the fixing member includes a second driving ramp that can abut against the locking member to drive the locking member to move relative to the mounting member.

[0019] In this design, the fixing component is equipped with a second driving ramp, which serves as a guide surface. Specifically, when the door assembly of the cooking appliance is in the open state, the locking component is in the locked position. The user can drive the locking component to the unlocked position by pressing the rotating component. However, because the fixing component has a second driving ramp, when the user wants to close the door assembly, the second driving ramp can contact the locking component. The pushing force of the fixing component on the locking component has a component force that pushes the locking component towards the rotating component, thus allowing the locking component to move towards the rotating component and disengage from the locked position. When the door assembly moves to the closed position, the fixing component no longer pushes the locking component. At this time, under the elastic force of the first elastic component, the locking component moves to the position where it locks with the fixing component. By providing a second driving ramp on the fixing component, during the process of closing the door assembly, the user does not need to actively switch the locking component to the unlocked position; the locking component can automatically switch positions, simplifying the user's operation and further improving the user's convenience in using the locking component.

[0020] In one possible design, the driving component includes: a second elastic element, the first end of which abuts against the rotating component, and the second end of which is connected to the mounting component. When the rotating component is in the first position, the second elastic element is in its original state, and when the rotating component is in the second position, the second elastic element is in an elastic deformation state.

[0021] In this design, the driving component is defined as a second elastic element. This second elastic element is disposed within the mounting component and abuts against the rotating component and the mounting component. Thus, the cooperation between the first and second elastic elements further enhances the stability of the locking component.

[0022] Specifically, before the user presses the rotating component, the second elastic component pushes the rotating component to the first position. At this time, the second elastic component is in its original state, while the first elastic component is in a compressed state. When the user presses the rotating component, the second elastic component is in a compressed state, while the first elastic component is in its original state.

[0023] When the user stops pressing and rotating, the second elastic element can automatically push the rotating element to the position that pushes the locking element, ensuring that the locking element can be stably locked.

[0024] In other designs, the drive element can also be an electrically driven structure, such as driving the rotating parts to rotate via a motor or cylinder.

[0025] In one possible design, the elastic coefficient of the second elastic element is greater than that of the first elastic element.

[0026] In this design, because the elastic coefficient of the second elastic element is greater than that of the first elastic element, when the deformation of the first and second elastic elements is the same or similar, the elastic force of the second elastic element is greater than that of the first elastic element. When the user stops pressing the rotating component, it is ensured that the second elastic element can overcome the elastic force of the first elastic element and push the rotating component to the first position.

[0027] In one possible design, the mounting component includes: a first guide groove and a second guide groove, the first guide groove and the second guide groove being disposed on two opposite sidewalls of the mounting component; the rotating component includes: a rotating plate; a first sliding part disposed on a first side of the rotating plate; a second sliding part disposed on a second side of the rotating plate, the first sliding part and the second sliding part being capable of sliding in opposite directions within the first guide groove and the second guide groove around the rotation center of the rotating plate.

[0028] In this design, a first guide groove and a second guide groove are respectively provided on two opposite side walls of the mounting component. A first sliding part is provided on the first side of the rotating plate, extending into and sliding within the first guide groove. A second sliding part is provided on the second side of the rotating plate, extending into and sliding within the second guide groove. When the first side of the rotating plate is pressed, the second side of the rotating plate tilts up, at which point the locking member moves to the unlocked position under the elastic force of the first elastic member. When the user stops pressing the rotating plate, the second elastic member pushes the rotating plate to rotate and reset, and the rotating plate pushes the locking member to the locked position.

[0029] The first guide groove guides the first sliding part, and the second guide groove guides the second sliding part, so that the rotating plate can rotate in a fixed direction and improve the stability of the rotating plate when rotating.

[0030] In one possible design, the locking assembly further includes a pusher that is slidable within the mounting and abuts against the rotating member. When the pusher is in its original position, the rotating member is in a first position, and when the pusher is in its pusher position, the rotating member is in a second position.

[0031] In this design, the push-button can slide within the receiving part, allowing the user to press it to push the rotating component. The push-button has a large surface area and a large contact area with the user's hand, improving the ease of operation for the locking component. Furthermore, the push-button effectively blocks the opening of the mounting component, preventing impurities from entering and reducing the likelihood of jamming due to contaminants, thus enhancing the functional stability of the lock structure.

[0032] In one possible design, the pressing part includes: a pressing plate, which is slidably connected to the mounting member; and a pushing part, which is disposed on the pressing plate and abuts against the rotating member. The pushing part and the locking member are located on both sides of the rotation center of the rotating member.

[0033] In this design, the push plate is slidably connected to the mounting component, ensuring that the pusher can slide stably along a preset direction, thereby allowing the pusher to stably push the rotating component. The pusher and locking components are located on either side of the rotating component's rotation center. When the user presses the push plate, the pusher abuts against one side of the rotating component's rotation center, pushing the rotating component. When the user stops pressing the push plate, the other side of the rotating component's rotation center pushes the locking component to the locked position. By placing the pusher and locking components on either side of the rotating component's rotation center, the ease of driving the rotating component is effectively improved.

[0034] In one possible design, the mounting element can be detachably connected to the surface to be mounted.

[0035] In this design, the mounting component can be detachably connected to the surface of the cooking appliance to be installed, meaning it can be removed from the appliance. When the lock structure is damaged, it can be removed from the mounting surface, preventing situations where the cooking appliance cannot be opened or closed due to lock structure damage, thus improving user convenience. Furthermore, when the lock structure is damaged, it can be disassembled, replaced, and maintained independently without dismantling the appliance's housing or other components, reducing maintenance difficulty and costs.

[0036] In one possible design, the mounting component includes: a mounting portion having a first opening and a first side surface for detachably connecting to the surface to be mounted; a support portion having a first end connected to the first side surface and having a communicating second opening and a receiving portion, the second opening being located at a second end of the support portion, a locking member extending into the receiving portion through the first opening, the locking member being movable relative to the second opening and locking or separating from the fixing member.

[0037] In this design, the locking member moves relative to the second opening and engages or disengages with the fixing member. When the locking member extends outward from the second opening, it engages with the fixing member; when it extends inward from the second opening, it disengages from the fixing member. The first end of the support portion is connected to the mounting portion, and the second end of the support portion has a second opening, so the user needs to press the locking member through the first opening. Furthermore, since the first side of the mounting portion can connect to the surface to be mounted, the mounting portion is mounted on the outer surface of the cooking appliance. The mounting portion is detachably connected to the outer surface of the cooking appliance. When the lock structure is damaged and the door of the cooking appliance cannot be opened, the mounting portion can be detached from the outer surface of the cooking appliance. This method of detaching the lock structure from the outside of the cooking appliance allows the door to be opened even if the lock structure is damaged, further improving the user's convenience in using the lock structure.

[0038] In one possible design, the mounting portion extends beyond the circumferential edge of the support portion, and the mounting portion extending beyond the circumferential edge of the support portion is used to abut against the surface to be mounted.

[0039] In this design, the end of the mounting part facing the support part is the first side surface, and the end of the support part facing the mounting part is the second side surface. The area of ​​the first side surface is larger than the area of ​​the second side surface, allowing the mounting part to extend beyond the circumferential edge of the support part. Since the first side surface of the mounting part is used to connect with the surface to be mounted, the portion of the mounting part extending beyond the circumferential edge of the support part can contact the surface to be mounted, resulting in a larger contact area between the mounting part and the surface to be mounted, thus improving the connection stability between the lock structure and the outer surface of the cooking appliance.

[0040] Secondly, the present invention provides a cooking appliance comprising: a cavity assembly; a door assembly, the door assembly being openably and closedly connected to the cavity assembly; a locking structure as described in any of the above possible designs; wherein a fixing member is disposed in one of the cavity assembly and the door assembly, and a locking member is disposed in the other of the cavity assembly and the door assembly.

[0041] The cooking appliance provided by this invention has all the benefits of the locking structure provided in any of the above-mentioned technical solutions.

[0042] 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 provided with a locking member. The locking member cooperates with the fixing member to lock the door assembly onto the cavity assembly. Specifically, the locking member is a child lock and serves as an auxiliary connection.

[0043] 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 is separated from the fixing element.

[0044] 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.

[0045] 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.

[0046] When the lock mechanism is damaged, it can be disassembled from the cavity assembly or door assembly, preventing the cooking appliance from being unable to open or close due to lock mechanism failure, thus improving user convenience. Furthermore, when the lock mechanism is damaged, it can be disassembled, replaced, and maintained independently without dismantling the cooking appliance's housing or other components, reducing maintenance difficulty and costs.

[0047] In one possible design, the cavity assembly includes: a cavity body; and a cover surrounding at least a portion of the cavity body.

[0048] 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.

[0049] In one possible design, the door assembly also includes: a door body; a door seal connected to the door body; and a latch, disposed on the door body or the door seal, for opening and closing connection with the cavity assembly.

[0050] 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.

[0051] 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.

[0052] In one possible design, a locking component is provided in the cavity assembly, the mounting part in the mounting member is connected to the outer surface of the cover, the cover is provided with a mounting hole, and the bearing part in the mounting member can pass through the mounting hole.

[0053] In this design, the mounting part is detachably connected to the outer surface of the cover. When the lock structure is damaged and the door assembly of the cooking appliance cannot be opened, the mounting part can be detached from the outer surface of the cover. This method of removing the lock structure from the outside of the cooking appliance allows the door assembly to be opened even if the lock structure is damaged, improving the user's convenience in using the cooking appliance.

[0054] In some possible designs, fasteners are installed on the door assembly and connected to the door body.

[0055] 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.

[0056] 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.

[0057] In some possible designs, the fastener is installed on the door assembly and connected to the door seal.

[0058] 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.

[0059] 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.

[0060] In some possible designs, the fastener is installed on the door assembly, and the fastener and the door body are an integral structure.

[0061] 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 the fastener and the entire cooking appliance.

[0062] In some possible designs, the fastener is installed on the door assembly, and the fastener and door seal are an integrated structure.

[0063] 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 seal. Specifically, this integral structure reduces the need for connecting parts between the fastener and the door seal, 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 the fastener and the entire cooking appliance.

[0064] In one possible design, a fastener is installed on the cavity assembly and connected to the cavity body.

[0065] In this design, the fastener can be located within the cavity assembly. When the fastener is located within the cavity assembly, it can be connected to the cavity body. In this case, the locking assembly is located within the door assembly, ensuring that the locking assembly corresponds in position to the fastener. Specifically, the fastener and the cavity body can be connected using fasteners such as screws, or they can be engaged using snap-fit ​​connections.

[0066] In addition, the cavity assembly itself has good strength and hardness. 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.

[0067] In one possible design, a fastener is installed on the cavity assembly and connected to the cover.

[0068] In this design, the fastener can be located within the cavity assembly. When the fastener is located within the cavity assembly, it can be connected to the cover. In this case, the locking assembly is located within the door assembly, ensuring that the locking assembly corresponds in position to the fastener. Specifically, the fastener and the cover can be connected using fasteners such as screws, or they can be engaged using snap-fit ​​connections.

[0069] 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.

[0070] In one possible design, a locking component is provided on the door assembly, the mounting part of the mounting member is connected to the outer surface of the door body, the door body is provided with mounting holes, and the bearing part of the mounting member can pass through the mounting holes.

[0071] In this design, the mounting part is detachably connected to the outer surface of the door body. When the lock structure is damaged and the door assembly of the cooking appliance cannot be opened, the mounting part can be detached from the outer surface of the door body. This method of disassembling the lock structure from the outside of the cooking appliance allows the door assembly to be opened even if the lock structure is damaged, improving the user's convenience in using the cooking appliance.

[0072] In one possible design, the cooking appliance includes a microwave oven, oven, steam oven, or steam oven.

[0092] The following reference Figures 1 to 13This invention describes a lock structure and a cooking appliance provided according to some embodiments of the invention.

[0093] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in an embodiment of the present invention, a lock structure is proposed, including: a fixing member 100 and a locking assembly 200, wherein the locking assembly 200 includes: a mounting member 210, a rotating member 220, a first elastic member 230, a locking member 240, and a driving member 250. At least a portion of the rotating member 220 is disposed within the mounting member 210, and the rotating member 220 can rotate within the mounting member 210; the second end of the first elastic member 230 is connected to the mounting member 210; the locking member 240 is connected to the first elastic member 230. At one end, the first end of the locking member 240 abuts against the rotating member 220. When the rotating member 220 rotates to the first position, the first elastic member 230 is in an elastic deformation state. The second end of the locking member 240 is locked with the fixing member 100. When the rotating member 220 rotates to the second position, the first elastic member 230 is in its original state, and the second end of the locking member 240 is separated from the fixing member 100. The driving member 250 is provided on the mounting member 210. The driving member 250 is used to drive the rotating member 220 to move from the second position to the first position.

[0094] The lock structure provided in this embodiment includes a fixing member 100 and a locking component 200. The locking component 200 and the fixing member 100 can be used together to achieve a locking and limiting function. Specifically, the lock structure proposed in this invention can be applied to cooking utensils and used as a child lock for cooking utensils.

[0095] Specifically, the locking assembly 200 includes a mounting member 210, a rotating member 220, a first elastic member 230, and a locking member 240. The mounting member 210 is mounted on an external object (e.g., a door assembly 400 or a cavity assembly 300 of a cooking appliance); at least a portion of the rotating member 220 is disposed within the mounting member 210; and the second end of the first elastic member 230 is connected to the locking member 240, while the second end of the first elastic member 230 is connected to the mounting member 210. Thus, the rotating member 220 can apply a pushing force to the locking member 240, at which point the first elastic member 230 undergoes elastic deformation. When the rotating member 220 stops pushing the locking member 240, the first elastic member 230 causes the locking member 240 to move and reset. The locking member 240 moves relative to the mounting member 210 under the drive of the rotating member 220 and the first elastic member 230, thereby causing the locking member 240 to pass through the mounting member 210 and lock with or separate from the fixing member 100.

[0096] Figure 3 The image shows the locking assembly 200 separated from the fixing member 100. Figure 4The image shows the locking assembly 200 locked to the fastener 100.

[0097] Specifically, in the lock structure proposed in this invention, the first elastic member 230 abuts between the mounting member 210 and the locking member 240, thereby achieving a flexible connection between the locking member 240 and the mounting member 210. Thus, when the locking assembly 200 is in the locked position, the presence of the first elastic member 230 allows the locking member 240 to still move towards the rotating member 220.

[0098] Specifically, the fixing member 100 and the locking assembly 200 can be installed on the cavity assembly 300 and the door assembly 400, respectively. Therefore, when the door assembly 400 is open, if the user accidentally closes the locking assembly 200, the fixing member 100 will come into contact with the locking member 240 during the process of closing the door assembly 400 without switching the position of the locking member 240, thereby forcing the locking member 240 to move towards the rotating member 220. In this way, on the one hand, it can ensure that the locking member 240 and the fixing member 100 can be connected and limited, and on the other hand, the connection and limitation of the locking member 240 and the fixing member 100 do not require user operation, which greatly improves the ease of use of the locking assembly 200.

[0099] When the door assembly 400 is in the closed state, the locking member 240 is in the locked position; at this time, the locking member 240 is limited in connection with the fixing member 100, and the user cannot open the door assembly 400. Before opening the door assembly 400, the connection limitation between the locking member 240 and the fixing member 100 is released; at this time, the locking member 240 is in the unlocked position, and the locking member 240 is separated from the fixing member 100.

[0100] When the door assembly 400 is opened, once the user switches the locking member 240 to the locked position, the first elastic member 230 abuts against the locking member 240 and the mounting member 210, creating an elastic connection between them. This ensures that the locking member 240 remains locked and limited by the fixing member 100 even when the door assembly 400 is closed, without requiring the user to switch its position beforehand.

[0101] Specifically, the locking structure proposed in this invention can be applied to cooking appliances. After the cooking process is finished, the food inside the cooking cavity is still hot, and there is a risk of burns if the user directly opens the door to remove the food. Therefore, this invention, through the cooperation of the locking component 200 and the fixing member 100, requires the user to pull the locking member 240 while opening the door component 400. This serves as a reminder to the user and prevents children from accidentally opening the door component 400, greatly improving the safety of the cooking appliance.

[0102] Therefore, the lock structure proposed in this invention, through the cooperation of the locking component 200 and the fixing member 100, increases the difficulty of unlocking the lock structure, preventing users, especially children, from accidentally opening the door component 400, and improving the safety of cooking utensils using this lock structure. Furthermore, the flexible connection between the driving component 250 and the locking component 240 allows the door component 400 to be closed without driving the locking component 240, even if the user accidentally switches the locking component 240 to the locked position when the door component 400 is open, while maintaining the connection limit between the locking component 240 and the fixing member 100.

[0103] The drive member 250 can drive the rotating member 220 to move from the second position to the first position. When the user stops pressing the rotating member 220, the drive member 250 drives the rotating member 220 to move to the first position. At this time, the rotating member 220 pushes the locking member 240 to the locked position. By setting the drive member 250 in the mounting member 210, it is ensured that the rotating member 220 can automatically move to the second position.

[0104] When the lock structure is damaged, it can be disassembled from the cavity assembly 300 or the door assembly 400, preventing the cooking appliance from being unable to open or close due to lock structure damage, thus improving user convenience. Furthermore, when the lock structure is damaged, it can be disassembled, replaced, and maintained independently without disassembling the cooking appliance's housing or other components, reducing maintenance difficulty and saving costs.

[0105] In one possible application, the fixing member 100 is provided with a groove. When the locking member 240 is in the locked position, a portion of the locking member 240 is inserted into the groove, and the locking member 240 and the groove cooperate to prevent the locking member 240 from separating from the fixing member 100. Alternatively, a through hole can be provided on the fixing member 100. When the locking member 240 is in the locked position, a portion of the locking member 240 is inserted into the through hole, and the locking member 240 and the through hole cooperate to prevent the locking member 240 from separating from the fixing member 100.

[0106] Combination Figure 1 and Figure 4 As shown, in one possible embodiment, the locking member 240 includes a first driving ramp 241, and the fixing member 100 is capable of abutting against the first driving ramp 241 to drive the locking member 240 to move relative to the mounting member 210.

[0107] In this embodiment, the locking member 240 is provided with a first driving ramp 241, which can serve as a guide surface. Specifically, when the door assembly 400 of the cooking appliance is in the open state, the locking member 240 is in the locked position. The user can drive the locking member 240 to the unlocked position by pressing the rotating member 220. However, since the locking member 240 is provided with the first driving ramp 241, when the user wants to close the door assembly 400, the first driving ramp 241 can contact the fixing member 100. The pushing force of the fixing member 100 on the locking member 240 has a component force that pushes the locking member 240 toward the rotating member 220. Therefore, the locking member 240 can move toward the rotating member 220, causing the locking member 240 to disengage from the locked position. When the door assembly 400 moves to the closed position, the fixing member 100 no longer pushes the locking member 240. At this time, under the elastic force of the first elastic member 230, the locking member 240 moves to the position where it locks with the fixing member 100. By providing a first driving inclined surface 241 on the locking member 240, during the process of closing the door assembly 400, the user does not need to actively switch the locking member 240 to the unlocked position; the locking member 240 can automatically switch positions, simplifying the user's operation and further improving the user's convenience in using the locking member 240.

[0108] Combination Figure 4 and Figure 11 As shown, in one possible embodiment, the fixing member 100 includes a second driving ramp 110, which is capable of abutting against the locking member 240 to drive the locking member 240 to move relative to the mounting member 210.

[0109] In this embodiment, the locking member 240 is provided with a first driving ramp 241, and the fixing member 100 is provided with a second driving ramp 110. The first driving ramp 241 and the second driving ramp 110 can serve as guide surfaces. Specifically, when the door assembly 400 of the cooking appliance is in the open state, the locking member 240 is in the locked position. The user can drive the locking member 240 to the unlocked position by pressing the rotating member 220. However, since the locking member 240 is provided with the first driving ramp 241 and the fixing member 100 is provided with the second driving ramp 110, when the user wants to close the door assembly 400, the first driving ramp 241 and the second driving ramp 110 come into contact and can slide relative to each other. Therefore, the locking member 240 can move toward the rotating member 220, causing the locking member 240 to disengage from the locked position. When the door assembly 400 moves to the closed position, the fixing member 100 no longer pushes the locking member 240. At this time, under the elastic force of the first elastic member 230, the locking member 240 moves to the position where it locks with the fixing member 100. By providing the first driving ramp 241 and the second driving ramp 110 on the fixing member 100, during the process of closing the door assembly 400, the user does not need to actively switch the locking member 240 to the unlocked position. The locking member 240 can automatically switch positions, simplifying the user's operation and further improving the user's convenience in using the locking member 240.

[0110] In one possible embodiment, the locking member 240 includes: a first driving ramp 241, to which the fixing member 100 can abut; the fixing member 100 includes: a second driving ramp 110, to which the second driving ramp 110 can abut against the first driving ramp 241 of the locking member 240.

[0111] In this embodiment, the fixing member 100 is provided with a second driving ramp 110, which can serve as a guide surface. Specifically, when the door assembly 400 of the cooking appliance is in the open state, the locking member 240 is in the locked position. The user can drive the locking member 240 to the unlocked position by pressing the rotating member 220. However, since the fixing member 100 is provided with the second driving ramp 110, when the user wants to close the door assembly 400, the second driving ramp 110 can contact the locking member 240. The pushing force of the fixing member 100 on the locking member 240 has a component force that pushes the locking member 240 toward the rotating member 220. Therefore, the locking member 240 can move toward the rotating member 220, causing the locking member 240 to disengage from the locked position. When the door assembly 400 moves to the closed position, the fixing member 100 no longer pushes the locking member 240. At this time, under the elastic force of the first elastic member 230, the locking member 240 moves to the position where it locks with the fixing member 100. By providing a second driving ramp 110 on the fixing member 100, during the closing process of the door assembly 400, the user does not need to actively switch the locking member 240 to the unlocked position; the locking member 240 can automatically switch positions, simplifying the user's operation and further improving the user's convenience in using the locking member 240.

[0112] Combination Figure 1 , Figure 2 and Figure 5 As shown, in one possible embodiment, the driving member 250 includes: a second elastic member, the first end of the second elastic member abutting against the rotating member 220, the second end of the second elastic member being connected to the mounting member 210, the second elastic member being in its original state when the rotating member 220 is in the first position, and the second elastic member being in an elastic deformation state when the rotating member 220 is in the second position.

[0113] In this embodiment, the driving member 250 is defined as the second elastic member. The second elastic member is disposed within the mounting member 210 and abuts against the rotating member 220 and the mounting member 210. Thus, the cooperation between the first elastic member 230 and the second elastic member further enhances the stability of the locking member 240.

[0114] Specifically, before the user presses the rotating member 220, the second elastic member will push the rotating member 220 to the first position. At this time, the second elastic member is in the original state, while the first elastic member 230 is in the compressed state. When the user presses the rotating member, the second elastic member is in the compressed state, while the first elastic member 230 is in the original state.

[0115] When the user stops pressing and rotating, the second elastic element can automatically push the rotating element 220 to a position that pushes the locking element 240, ensuring that the locking element 240 can be stably locked.

[0116] In other embodiments, the drive member 250 may also be an electrically driven structure, for example, the rotating member 220 may be driven to rotate by a motor or cylinder.

[0117] In one possible application, both the first elastic element 230 and the second elastic element are compression springs.

[0118] In one possible embodiment, the elastic coefficient of the second elastic element is greater than that of the first elastic element 230.

[0119] In this embodiment, since the elastic coefficient of the second elastic element is greater than that of the first elastic element 230, when the deformation of the first elastic element 230 and the second elastic element is the same or similar, the elastic force of the second elastic element is greater than that of the first elastic element 230. When the user stops pressing the rotating member 220, it is ensured that the second elastic element can overcome the elastic force of the first elastic element 230 and push the rotating member 220 to the first position.

[0120] Combination Figure 1 , Figure 2 and Figure 5 As shown, in one possible embodiment, the mounting member 210 includes: a first guide groove 211 and a second guide groove 212, the first guide groove 211 and the second guide groove 212 being disposed on two opposite sidewalls of the mounting member 210; the rotating member 220 includes: a rotating plate 221, a first sliding part 222 and a second sliding part 223; the first sliding part 222 is disposed on a first side of the rotating plate 221, and the first sliding part 222 can slide within the first guide groove 211; the second sliding part 223 is disposed on a second side of the rotating plate 221, and the first sliding part 222 and the second sliding part 223 can slide in opposite directions within the first guide groove 211 and the second guide groove 212 around the rotation center of the rotating plate 221.

[0121] In this embodiment, a first guide groove 211 and a second guide groove 212 are respectively provided on two opposite sidewalls of the mounting member 210. A first sliding part 222 is provided on the first side of the rotating plate 221, extending into the first guide groove 211 and sliding within it. A second sliding part 223 is provided on the second side of the rotating plate 221, extending into the second guide groove 212 and sliding within it. When the first side of the rotating plate 221 is pressed, the second side of the rotating plate 221 tilts up, at which time the locking member 240 moves to the unlocked position under the elastic force of the first elastic member 230. When the user stops pressing the rotating plate 221, the second elastic member pushes the rotating plate 221 to rotate and reset, and the rotating plate 221 pushes the locking member 240 to move to the locked position.

[0122] The first guide groove 211 guides the first sliding part 222, and the second guide groove 212 guides the second sliding part 223, so that the rotating plate 221 can rotate in a fixed direction, thereby improving the stability of the rotating plate 221 when it rotates.

[0123] In one possible application, the first guide groove 211 is lower than the second guide groove 212, which can prevent the rotating part 220 from overturning.

[0124] Combination Figure 1 , Figure 2 and Figure 5 As shown, in one possible embodiment, the locking assembly 200 further includes a push part 260, which is slidable within the mounting member 210 and abuts against the rotating member 220. When the push part 260 is in the original position, the rotating member 220 is in a first position, and when the push part 260 is in the push position, the rotating member 220 is in a second position.

[0125] In this embodiment, the push part 260 can slide within the receiving part. The user can press the push part 260 to push the rotating member 220. The area of ​​the push surface of the push part 260 is large, and the contact area between the push part 260 and the user's hand is large, which can improve the user's ease of driving the locking member 240. Moreover, the push part 260 can block the opening of the mounting member 210, preventing impurities from entering the mounting member 210. The internal structure of the lock is less likely to jam due to impurities, which is beneficial to improving the functional stability of the lock structure.

[0126] Combination Figure 1 , Figure 2 , Figure 5 and Figure 9 As shown, in one possible embodiment, the pressing part 260 includes: a pressing plate 261 and a pushing part 262. The pressing plate 261 is slidably connected to the mounting member 210. The pushing part 262 is disposed on the pressing plate 261 and abuts against the rotating member 220. The pushing part 262 and the locking member 240 are located on both sides of the rotation center of the rotating member 220.

[0127] In this embodiment, the push plate 261 is slidably connected to the mounting member 210, ensuring that the push member can slide stably in a preset direction, thereby enabling the push part 262 to stably push the rotating member 220. The push part 262 and the locking member 240 are located on both sides of the rotation center of the rotating member 220. When the user presses the push plate 261, the push part 262 abuts against one side of the rotation center of the rotating member 220, at which time the push part 262 pushes the rotating member 220. When the user stops pressing the push plate 261, the other side of the rotation center of the rotating member 220 pushes the locking member 240 to the locked position. By placing the push part 262 and the locking member 240 on both sides of the rotation center of the rotating member 220, the ease of driving the rotating member 220 can be effectively improved.

[0128] In one possible embodiment, the mounting element 210 can be detachably connected to the surface to be mounted.

[0129] In this embodiment, the mounting component 210 can be detachably connected to the surface of the cooking appliance to be installed, meaning the mounting component 210 can be removed from the cooking appliance. When the lock structure is damaged, the lock structure can be removed from the surface to be installed, preventing the cooking appliance from being unable to be opened or closed due to lock structure damage, thus improving the user's convenience in using the lock structure. Moreover, when the lock structure is damaged, the lock structure can be disassembled, replaced, and maintained separately without disassembling the cooking appliance's housing or other components, reducing maintenance difficulty and saving maintenance costs.

[0130] Combination Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in one possible embodiment, the mounting member 210 includes a mounting portion 213 and a supporting portion 214. The mounting portion 213 is provided with a first opening 2131 and a first side surface for detachably connecting to the surface to be mounted. The first end of the supporting portion 214 is connected to the first side surface. The supporting portion 214 is provided with a communicating second opening and a receiving portion. The second opening is located at the second end of the supporting portion 214. The locking member 240 extends into the receiving portion through the first opening 2131. The locking member 240 can move relative to the second opening and lock or separate from the fixing member 100.

[0131] In this embodiment, the locking member 240 moves relative to the second opening and locks or separates from the fixing member 100. When the locking member 240 extends outward from the second opening, it locks with the fixing member 100; when it extends inward from the second opening, it separates from the fixing member 100. The first end of the supporting part 214 is connected to the mounting part 213, and the second end of the supporting part 214 is provided with the second opening, so the user needs to press the locking member 240 through the first opening 2131. Moreover, since the first side of the mounting part 213 can connect with the surface to be installed, the mounting part 213 is installed on the outer surface of the cooking appliance. The mounting part 213 is detachably connected to the outer surface of the cooking appliance. When the lock structure is damaged and the door of the cooking appliance cannot be opened, the mounting part 213 can be detached from the outer surface of the cooking appliance from the outside. The method of disassembling the lock structure from the outside of the cooking appliance allows the appliance door to be opened even if the lock structure is damaged, further improving the user's convenience in using the lock structure.

[0132] In one possible embodiment, the mounting portion 213 extends beyond the circumferential edge of the support portion 214, and the mounting portion 213 extending beyond the circumferential edge of the support portion 214 is used to abut against the surface to be mounted.

[0133] In this embodiment, the end of the mounting portion 213 facing the support portion 214 is a first side surface, and the end of the support portion 214 facing the mounting portion 213 is a second side surface. The area of ​​the first side surface is larger than the area of ​​the second side surface, allowing the mounting portion 213 to extend beyond the circumferential edge of the support portion 214. Since the first side surface of the mounting portion 213 is used to connect with the surface to be mounted, the portion of the mounting portion 213 extending beyond the circumferential edge of the support portion 214 can contact the surface to be mounted. The mounting portion 213 and the surface to be mounted have a large contact area, improving the connection stability between the lock structure and the outer surface of the cooking appliance.

[0134] Combination Figure 3 , Figure 4 , Figure 10 , Figure 12 and Figure 13 As shown, in some embodiments of the invention, a cooking appliance is provided, comprising: a cavity assembly 300, a door assembly 400, and a locking structure as described in any of the above embodiments. The door assembly 400 is openably connected to the cavity assembly 300; wherein a fixing member 100 is disposed in one of the cavity assembly 300 and the door assembly 400, and a locking member 200 is disposed in the other of the cavity assembly 300 and the door assembly 400.

[0135] The cooking appliance provided in this embodiment has all the benefits of the lock structure provided in any of the above embodiments.

[0136] The cooking appliance proposed in this embodiment includes a cavity assembly 300, a door assembly 400, and a locking structure of any of the designs described above. The cavity assembly 300 includes a cooking cavity for holding food to be cooked. The door assembly 400 is connected to the cavity assembly 300 and is used to open or close the cooking cavity. Specifically, the door assembly 400 can be rotatably connected to the cavity assembly 300 or slidably connected to it. One of the cavity assembly 300 and the door assembly 400 is provided with a fixing member 100, and the other is provided with a locking component 200. The locking component 200 cooperates with the fixing member 100 to lock the door assembly 400 onto the cavity assembly 300. Specifically, the locking component 200 is a child lock and serves as an auxiliary connection.

[0137] When the door assembly 400 is in the closed state, the locking member 240 is in the locked position; at this time, the locking member 240 is limited in connection with the fixing member 100, and the user cannot open the door assembly 400. Before opening the door assembly 400, the connection limitation between the locking member 240 and the fixing member 100 is released; at this time, the locking member 240 is in the unlocked position, and the locking member 240 is separated from the fixing member 100.

[0138] During the opening of the door assembly 400, the door assembly 400 can be directly driven to separate from the cavity assembly 300 to complete the opening operation; at this time, the locking member 240 is still in the unlocking position. During the closing of the door assembly 400, the door assembly 400 can be directly closed and the position of the locking member 240 can be switched again, so that the locking member 240 is connected and limited to the fixing member 100.

[0139] In one possible embodiment, the cavity assembly 300 includes a cavity body 310 and a cover 320, the cover 320 surrounding at least a portion of the cavity body 310.

[0140] In this embodiment, the cavity assembly 300 includes a cavity body 310 and a cover 320. The cavity body 310 has a cooking cavity for holding food to be cooked. The cover 320 surrounds at least a portion of the cavity body 310, thus providing good protection for the cavity body 310. Furthermore, a mounting cavity exists between the cavity body 310 and the cover 320, allowing relevant components of the cooking appliance to be installed within this mounting cavity.

[0141] In one possible embodiment, the door assembly 400 further includes: a door body 410, a door seal 420, and a latch 430, wherein the door seal 420 is connected to the door body 410; and the latch 430 is disposed on the door body 410 or the door seal 420 for opening and closing connection with the cavity assembly 300.

[0142] In this embodiment, the door assembly 400 includes a door body 410, a door seal 420, and a latch 430. The door body 410 is connected to the cavity assembly 300 for opening and closing, and can be used to open or close the cooking cavity. The door seal 420 is connected to the door body 410 and provides a good sealing function when the door body 410 closes the cooking cavity, ensuring a good sealing effect during operation. Furthermore, the latch 430 is provided with either the door body 410 or the door seal 420 and is connected to the cavity assembly 300 for opening and closing. When the door body 410 closes the cooking cavity, the latch 430 is connected to the cavity assembly 300 to ensure the connection between the door assembly 400 and the cavity assembly 300.

[0143] Specifically, the door assembly 400 of the cooking appliance proposed in this invention includes a latch 430, which is used to connect with the cavity assembly 300, thereby ensuring a stable connection between the door assembly 400 and the cavity assembly 300. That is, the cooking appliance proposed in this invention first ensures the connection between the door assembly 400 and the cavity assembly 300 through the latch 430, and then the locking assembly 200 can be used as a child lock, allowing the locking assembly 200 to cooperate with the fixing member 100 to further restrict the user from opening the door assembly 400.
