Description

Technical Field

[0001] The embodiments of the present invention relate to the field of kitchen appliance technology, and more specifically, to an interlocking system and a cooking appliance. Background Technology

[0002] Currently, microwave ovens in this technology do not have corresponding child lock protection devices. Children can easily accidentally touch the door opening button or handle, and can open the door with just a light press or pull, which can easily cause children to be burned by heated food. Summary of the Invention

[0003] The embodiments of the present invention are intended to at least solve one of the technical problems existing in the prior art.

[0004] Therefore, a first aspect of the embodiments of the present invention provides an interlocking system.

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

[0006] In view of the above, according to a first aspect of the present invention, an interlocking system is provided for cooperating with a door body, the door body including a door hook, the interlocking system including: a mating member having a mating groove, the mating member being movable to engage the door hook with the mating groove so that the door hook can move between an open position and a closed position; a limiting member movable between a first position and a second position; a transmission mechanism capable of pushing the limiting member from the first position to the second position; wherein, based on the limiting member being in the first position, the limiting member restricts the movement of the mating member so that the door hook is locked in the closed position; based on the limiting member being in the second position, the limiting member releases the restriction on the movement of the mating member, and the door hook can move to the open position.

[0007] The interlocking system provided in this embodiment of the invention includes a mating component, a limiting component, and a transmission mechanism. Specifically, the mating component is provided with a mating groove, which can engage with a door hook. Thus, when the mating component moves, it engages with the door hook through the mating groove, allowing the door hook to move between an open position and a closed position. It is understood that the mating component can move along opposite first and second directions. When the door is closed, the user pushes the door, causing the door hook to move. When the door hook reaches a certain position, it contacts the mating component and pushes it to move. That is, during the closing process, the door hook can push the mating component to move along the first direction, and the door hook slides into the mating groove. This allows the mating component to pull the door hook to the closed position during its movement, meaning the door is in the closed position.

[0008] When the door is opened, the user pulls the door handle, and the door moves the door hook. Since the door hook engages with the mating groove, the door hook moves the mating parts in the second direction during the opening process until the door hook slides out of the mating groove and the door is in the open position.

[0009] In practical applications, the door hook is fixed relative to the door body; that is, it is a fixed door hook. The opening and closing of the door is achieved through the cooperation of the fixed door hook and the mating groove. It is worth noting that the door body is equipped with an upper door hook and a lower door hook. Both the upper and lower door hooks can be fixed, or the lower door hook can be fixed while the upper door hook is movable. The specific configuration can be determined according to actual needs.

[0010] Microwave ovens in this technology allow users to open or close the cooking cavity by pulling or pressing the door to access food inside. However, because they lack child locks and the opening force is less than 25N, children can easily accidentally press the door button or pull the handle, opening the door with a light press or pull, resulting in burns from heated food or utensils inside the cooking cavity.

[0011] The limiting member can move between a first position and a second position, and the transmission mechanism can push the limiting member from the first position to the second position. Specifically, when the limiting member is in the first position, it can restrict the movement of the mating member. Since the limiting member restricts the movement of the mating member, and the mating groove of the mating member engages with the door hook, the door hook cannot move to the open position, even if the door hook is locked in the closed position. In other words, when the limiting member is in the first position, the door cannot be opened even if the door handle is pulled.

[0012] When the door needs to be opened, the transmission mechanism pushes the limiting member from the first position to the second position. When the limiting member is in the second position, it can release the movement restriction on the mating member. In other words, the mating member is unlocked. At this time, pulling the door handle will cause the door hook to move the mating member until the door hook slides out of the mating groove. The door hook then moves to the open position, thus opening the door.

[0013] By setting a limiting component that can move between a first position and a second position, when you want to open the door, you need to first have the transmission mechanism push the limiting component to the second position, thereby releasing the movement restriction on the mating parts, so that the door can be opened. This increases the steps to open the door, thus increasing the difficulty of opening the door. This reduces the risk of children accidentally touching the door opening button or handle, and being burned by the heated food or utensils inside the cooking cavity. It effectively avoids misoperation and thus effectively improves the safety of cooking appliances with this interlocking system.

[0014] Understandably, a portion of the transmission mechanism can be exposed outside the door, allowing the user to unlock the mating parts by operating the exposed portion of the transmission mechanism, thereby enabling the door to be opened.

[0015] The door is equipped with a handle, which users can pull to open the door, improving user convenience.

[0016] It is worth noting that the mating parts are provided with mating grooves, and part of the door hook is constructed as a protrusion. During the opening and closing of the door, the protrusion can slide into or out of the mating groove.

[0017] In addition, the interlocking system provided by the above-described technical solution of the present invention also has the following additional technical features:

[0018] In one possible technical solution, the transmission mechanism includes a fixed member and a transmission member, wherein the transmission member is disposed on the fixed member and is slidable relative to the fixed member, and the transmission member is capable of pushing the limiting member from a first position to a second position.

[0019] In this technical solution, the transmission mechanism is defined to include a fixed member and a transmission member. Specifically, the transmission member is disposed on the fixed member and can slide relative to the fixed member. Thus, when the transmission member slides relative to the fixed member, the transmission member can push the limiting member from the first position to the second position, so that the mating member is unlocked.

[0020] In detail, when the limiting member is in the first position, the limiting member can restrict the movement of the mating member. Since the limiting member restricts the movement of the mating member, and the mating groove of the mating member is engaged with the door hook, the door hook cannot move to the open position. Even if the door hook is locked in the closed position, that is to say, when the limiting member is in the first position, the door cannot be opened even if the door handle is pulled.

[0021] When the door needs to be opened, the transmission component slides relative to the fixed component, thereby pushing the limiting component from the first position to the second position. When the limiting component is in the second position, it can release the movement restriction on the mating component, that is, the mating component is unlocked. At this time, pulling the door handle will cause the door hook to move the mating component until the door hook slides out of the mating groove, thus moving the door to the open position and realizing the door opening operation.

[0022] By setting a limiting component that can move between a first position and a second position, when you want to open the door, you need to first slide the transmission component relative to the fixed component, and push the limiting component to the second position during the sliding process, thereby releasing the movement restriction on the mating component, so that the door can be opened. This increases the steps to open the door, thereby increasing the difficulty of opening the door. This reduces the risk of children being burned by the heated food or utensils in the cooking cavity due to accidentally touching the door opening button or handle and opening the oven door with a light press or pull. It effectively avoids accidental operation and thus effectively improves the safety of using cooking appliances with this interlocking system.

[0023] In one possible technical solution, the fixing member is provided with a sliding channel, and a part of the transmission member passes through the sliding channel and is able to slide within the sliding channel.

[0024] In this technical solution, the fixing member is provided with a sliding channel, a part of the transmission member passes through the sliding channel, and the transmission member can slide within the sliding channel. Thus, when the transmission member moves, it can slide relative to the fixing member within the sliding channel, and in the process of sliding, it pushes the limiting member to move so that the mating member is unlocked.

[0025] It is understandable that the sliding channel is a closed channel on all four sides, which limits the sliding trajectory of the transmission component during the sliding process, ensuring the stability of the movement of the transmission component within the sliding channel. This allows the transmission component to effectively push the limiting component during the sliding process, thereby enabling the mating component to be effectively unlocked and ensuring the stable operation of the door opening and closing.

[0026] In one possible technical solution, the interlocking system further includes a first elastic element, the first end of which is connected to a fixing element, and the second end of which is connected to a limiting element. The first elastic element is used to reset the limiting element after it moves.

[0027] In this technical solution, the interlocking system is further defined as including a first elastic element. Specifically, one end of the first elastic element is connected to the fixing element and the other end is connected to the limiting element. The first elastic element can cause the limiting element to reset after movement.

[0028] In detail, when the limiting member is in the first position, the limiting member can restrict the movement of the mating member. Since the limiting member restricts the movement of the mating member, and the mating groove of the mating member is engaged with the door hook, the door hook cannot move to the open position. Even if the door hook is locked in the closed position, that is to say, when the limiting member is in the first position, the door cannot be opened even if the door handle is pulled.

[0029] When the door needs to be opened, the transmission component slides relative to the fixed component, causing it to push the limiting component from a first position to a second position. When the limiting component is in the second position, it releases its restriction on the movement of the mating component. At this time, the first elastic component undergoes elastic deformation; for example, it is stretched. In other words, the mating component is unlocked. Pulling the door handle causes the door hook to move, until it slides out of the mating groove, thus moving the door to the open position and opening the door. After the door is opened, the first elastic component moves the limiting component in the direction of the first position, i.e., the first elastic component moves the limiting component in the opposite direction to reset it.

[0030] By setting the first elastic element, the limit element can be automatically reset after movement, ensuring the effective operation of the door opening and closing, improving the convenience of users using cooking appliances with this interlocking system, and thus enhancing the user experience.

[0031] In practical applications, the first elastic element is a tension spring.

[0032] In one possible technical solution, the interlocking system further includes a second elastic element, the first end of which is connected to the fixed element, and the second end of which is connected to the transmission element. The second elastic element is used to reset the transmission element after it has moved.

[0033] In this technical solution, the interlocking system is further defined as including a second elastic element. Specifically, one end of the second elastic element is connected to the fixed element, and the other end is connected to the transmission element. The second elastic element can cause the transmission element to move and then reset. That is, when the transmission element slides relative to the fixed element, so that the transmission element pushes the limiting element to the second position, the mating part is unlocked and the door is opened, the second elastic element can drive the transmission element to slide and reset in the opposite direction, so that when the door needs to be opened again after it is closed, the mating part can be unlocked by the movement of the transmission element.

[0034] By setting a second elastic element, the transmission component can be automatically reset after movement, improving the convenience for users to use cooking appliances with this interlocking system and thus enhancing the user experience.

[0035] Furthermore, when the transmission component moves and pushes the limiting component to the second position, thereby unlocking the mating component, the first elastic component drives the limiting component to automatically reset, and the second elastic component drives the transmission component to automatically reset. This means that the reset processes of the transmission component and the limiting component are performed separately, reducing the collision and wear that occur between the limiting component and the transmission component during the reset process, thereby extending the service life of the transmission component and the limiting component.

[0036] Furthermore, by setting the first and second elastic elements, the driving force that moves the transmission components can be increased, further increasing the difficulty of opening the door and further reducing the risk of children being burned by the heated food or utensils inside the cooking cavity due to accidentally touching the door opening button or handle and opening the oven door with a light press or pull. This effectively avoids misoperation and further improves the safety of using cooking appliances with this interlocking system.

[0037] In practical applications, the second elastic element is a tension spring.

[0038] In one possible technical solution, the transmission component includes a trigger part and a first transmission part, wherein the first transmission part is disposed on the trigger part and is used to push the limiting member to move from a first position to a second position.

[0039] In this technical solution, the transmission component is defined as including a trigger part and a first transmission part. Specifically, the first transmission part is disposed on the trigger part. When the trigger part is triggered, the trigger part can drive the first transmission part to slide relative to the fixed part. During the sliding process, the first transmission part pushes the limiting part to move to the second position to release the movement restriction on the mating part.

[0040] In detail, when the limiting member is in the first position, the limiting member can restrict the movement of the mating member. Since the limiting member restricts the movement of the mating member, and the mating groove of the mating member is engaged with the door hook, the door hook cannot move to the open position. Even if the door hook is locked in the closed position, that is to say, when the limiting member is in the first position, the door cannot be opened even if the door handle is pulled.

[0041] When the door needs to be opened, the trigger is activated. When the trigger is activated, it drives the first transmission part to slide relative to the fixed part. During the sliding process, the first transmission part pushes the limiting part from the first position to the second position. When the limiting part is in the second position, it can release the restriction on the movement of the mating part. At this time, the first elastic part and the second elastic part undergo elastic deformation. For example, both the first elastic part and the second elastic part are stretched. At this time, when the door handle is pulled, the door hook can drive the mating part to move until the door hook slides out of the mating groove, thus moving the door hook to the open position and realizing the door opening operation.

[0042] When the door is opened and the trigger is released, the first elastic element drives the limiting element to move in the direction of the first position, and the second elastic element drives the transmission element to move in the opposite direction and reset.

[0043] In practical applications, the trigger and the first transmission part are an integral structure. It is understood that the integral structure has good mechanical properties, which can improve the connection strength between the trigger and the first transmission part and ensure effective power transmission.

[0044] In addition, the integrated structure facilitates the processing and production of transmission components, thereby reducing the production cost of the interlocking system and cooking appliances with the interlocking system.

[0045] In one possible technical solution, the transmission component further includes a stop portion located at one end of the trigger portion. When the transmission component moves away from the limiting component, the stop portion can abut against the fixing component.

[0046] In this technical solution, the transmission component is further defined as including a stop part. Specifically, the stop part is disposed on one end of the trigger part. When the transmission component moves away from the limiting component, the stop part can abut against the fixing component to prevent the trigger part from moving excessively and to ensure the effective operation of the interlocking system's door opening and closing process.

[0047] In detail, when the trigger is activated, the actuating part causes the first transmission part and the stop part to slide relative to the fixed part, so that the first transmission part pushes the limiting part to move to the second position, thereby unlocking the mating part. After the door opening operation is completed, the trigger is released, and the first elastic member drives the limiting part to move in the direction of the first position. During the process of the second elastic member driving the transmission part to move in the opposite direction to reset, when it moves to a certain position, the stop part abuts against the fixed part, thereby completing the reset of the transmission part. That is, the stop part limits the reset process of the transmission part, preventing the transmission part from moving excessively, thereby ensuring the effective operation of the door opening and closing process and improving the stability and reliability of the door opening and closing process of cooking appliances with this interlocking system.

[0048] In practical applications, the stop part and the trigger part are integrated into one structure. It is understood that the integrated structure has good mechanical properties, which can improve the connection strength between the stop part and the trigger part, ensure effective power transmission, and at the same time ensure the effective limiting of the stop part when the trigger part is reset.

[0049] It is understandable that a portion of the triggering part may be exposed outside the door body, thus facilitating the user to drive the transmission component by operating the triggering part. The stop portion is located at the end of the triggering part opposite to the portion exposed outside the door body.

[0050] In addition, the integrated structure facilitates the processing and production of transmission components, thereby reducing the production cost of the interlocking system and cooking appliances with the interlocking system.

[0051] In one possible technical solution, the fixing member is provided with a first support portion; the interlocking system further includes a second support portion, which is disposed on the transmission member, located on the first support portion, and is slidable relative to the first support portion.

[0052] In this technical solution, the interlocking system is further defined as including a second support part. Specifically, the fixing member is provided with a first support part, and the second support part is provided on the transmission member. Specifically, the second support part is provided on the trigger part, and the second support part is located on the first support part and can slide relative to the first support part.

[0053] In other words, the second support is located above the first support, and during the process of the trigger being triggered and driving the first transmission part to slide relative to the fixed part, or the second elastic member driving the transmission part to reset, the second support can slide on the first support. Thus, while effectively realizing the door opening and closing process, the stability and reliability of the transmission part sliding relative to the fixed part are further improved through the cooperation and support between the first support and the second support, preventing the transmission part from shaking when sliding relative to the fixed part, and ensuring that the first transmission part can push the limiting member to the second position during the sliding process to unlock the cooperating part, thereby completing the door opening operation.

[0054] In addition, the fastener is used for the fixed connection of the transmission mechanism, and the second support part connected to the transmission part is located on the first support part, so that the first support part can support the second support part, thereby improving the installation stability of the transmission part.

[0055] In practical applications, the second support part and the trigger part are integrated into one structure.

[0056] In one possible technical solution, the limiting member includes a second transmission part, a connecting part, and a limiting part. The first transmission part can drive the second transmission part to move. The connecting part is connected to the second transmission part, and the limiting part is connected to the connecting part. Based on the limiting member being located in the first position, the limiting part restricts the movement of the mating part. The movement of the second transmission part can drive the limiting part to move from the first position to the second position through the connecting part.

[0057] In this technical solution, the limiting member is defined to include a second transmission part, a connecting part, and a limiting part. Specifically, the limiting part is connected to the connecting part, and the second transmission part is connected to the connecting part.

[0058] In detail, when the limiting member is in the first position, the limiting part can restrict the movement of the mating part. Since the limiting part restricts the movement of the mating part, and the mating groove of the mating part is engaged with the door hook, the door hook cannot move to the open position. Even if the door hook is locked in the closed position, that is, when the limiting member is in the first position, the door cannot be opened even if the door handle is pulled.

[0059] When the door needs to be opened, the trigger is activated. When the trigger is activated, it drives the first transmission part to slide relative to the fixed part. During the sliding process, the first transmission part pushes the second transmission part to move. The movement of the second transmission part drives the connecting part to move. The movement of the connecting part in turn drives the limiting part to move from the first position to the second position. When the limiting part is in the second position, the limiting part can release the movement restriction on the mating part. At this time, the first elastic element and the second elastic element undergo elastic deformation. For example, both the first elastic element and the second elastic element are stretched. At this time, when the door handle is pulled, the door hook can drive the mating part to move until the door hook slides out of the mating groove, thus moving the door hook to the open position and realizing the door opening operation.

[0060] Furthermore, when the door is opened and the trigger is released, the first elastic element drives the limiting element to move in the direction of the first position, and the second elastic element drives the transmission element to move in the opposite direction and reset.

[0061] In practical applications, the limiting part, the connecting part, and the second transmission part are integrated into one structure. It is understood that the integrated structure has good mechanical properties, which can improve the connection strength between the limiting part, the connecting part, and the second transmission part, and ensure effective power transmission.

[0062] In addition, the integrated structure facilitates the processing and production of limiting components, thereby reducing the production cost of the interlocking system and cooking appliances with the interlocking system.

[0063] In one possible technical solution, the limiting part is provided with a guide surface. The movement of the mating part causes the door hook to engage with the mating groove, so that during the process of the door hook moving to the closed position, the guide surface can guide a part of the mating part.

[0064] In this technical solution, the limiting part is provided with a guide surface. Specifically, when the mating part moves to make the door hook engage with the mating groove, and the door hook moves to the closed position, the guide surface can guide a part of the mating part, thereby ensuring the smooth closing process.

[0065] Specifically, when the limiting part is in the first position, it restricts the movement of a portion of the mating component, meaning the limiting part is located on the movement path of that portion, thus restricting the movement of the mating component and locking the door hook in the closed position. When it is necessary to open the door, the transmission component slides relative to the fixed component and pushes the second transmission component through the first transmission component, thereby moving the limiting part to the second position. This allows the limiting part to avoid the movement path of the portion of the mating component, at which point the portion of the mating component can move along the movement path, completing the door opening operation.

[0066] During the closing process, a part of the mating component pushes the limiting part to move along the movement path. At this time, the first elastic element is stretched. When the part of the mating component separates from the limiting part, the part of the mating component moves into place and completes the closing operation. The first elastic element drives the limiting part to return to the first position, that is, the limiting part is on the movement path of the part of the mating component, thereby restricting the movement of the mating component and realizing the child lock function.

[0067] During the closing process, as a portion of the mating part pushes the limiting part to move along the motion path, the guide surface can guide the movement of the portion of the mating part to ensure the smooth closing process.

[0068] In practical applications, the mating parts include a limiting post, and the guide surface can guide the movement of the limiting post on the movement path to complete the door closing operation.

[0069] In one possible technical solution, the interlocking system further includes a first bracket and a second bracket, wherein the mating member is rotatably disposed on the first bracket, the second bracket is connected to the first bracket and surrounds the first bracket to form a receiving cavity, a portion of the mating member is located in the receiving cavity, and a limiting member is rotatably disposed on the side of the second bracket away from the receiving cavity.

[0070] In this technical solution, the interlocking system further includes a first bracket and a second bracket. Specifically, the first bracket and the second bracket are connected, and the first bracket and the second bracket together form a receiving cavity, that is, the receiving cavity is formed by the side of the first bracket near the second bracket and the side of the second bracket near the first bracket. The mating component is located within the receiving cavity, meaning that the receiving cavity provides installation space for the mating component. This protects the mating component, prevents external forces from acting directly on it, and thus extends the service life of the mating component.

[0071] Furthermore, by placing a portion of the mating component within the accommodating cavity, it is possible to reduce the entry of dirt and impurities into the mating component, ensuring its cleanliness and thus guaranteeing the reliability of the mating of various components in the interlocking system.

[0072] The mating component is mounted on the first bracket and can rotate relative to the first bracket. That is, during the opening and closing of the door, the door hook engages with the mating groove of the mating component, thereby causing the mating component to rotate relative to the first bracket to complete the opening and closing operation.

[0073] The limiting member is located on the side of the second bracket away from the receiving cavity, and the limiting member can rotate relative to the second bracket. When the transmission member slides relative to the fixed member, the transmission member can push the limiting member to rotate from the first position to the second position, thereby releasing the movement restriction on the mating member. By pulling the door body, the door can be opened through the cooperation of the door hook and the mating member.

[0074] In one possible technical solution, the mating component is provided with a limiting post; the interlocking system further includes a first clearance opening, which is located on the second bracket, and the limiting post extends out of the second bracket through the first clearance opening and can move within the first clearance opening; wherein, based on the limiting component being located in the first position, the limiting post is located on the first side of the first clearance opening, and the limiting component prevents the limiting post from moving from the first side to the second side of the first clearance opening; based on the limiting component being located in the second position, the limiting post can move from the first side to the second side.

[0075] In this technical solution, the interlocking system is further defined as including a first clearance opening. Specifically, the first clearance opening is set on the second bracket, and the mating part is provided with a limit post. The limit post extends out of the second bracket through the first clearance opening, that is, the first clearance opening is connected to the receiving cavity.

[0076] During the opening and closing of the door, the limiting post can move within the first clearance opening. The second bracket includes a first side and a second side located in the first clearance opening and arranged opposite to each other. It is understood that when the limiting post is located on the first side, the door is closed, and when the limiting post moves from the first side to the second side, the door is opened.

[0077] In detail, when the door is in the closed state, the limiting member is in the first position and the limiting post is in the first side. At this time, since the limiting member is in the first position, the limiting post cannot move from the first side to the second side. That is, the limiting member blocks the movement path of the limiting post, thus restricting the movement of the limiting post, thereby restricting the movement of the mating parts so that the door hook is locked in the closed position.

[0078] When the transmission component slides relative to the fixed component, the transmission component pushes the limiting component to move from the first position to the second position. At this time, the limiting component avoids the movement path of the limiting post, and the limiting post can move from the first side to the second side, thereby realizing the door opening operation.

[0079] When the door is closed, the door hook pushes the mating component to rotate relative to the first bracket. At the same time, it drives the limiting post to move within the first clearance opening. During the movement of the limiting post, it pushes the limiting part to rotate relative to the second bracket and can be guided by the guide surface to the limiting post until the limiting part separates from the limiting post. The limiting post moves to the first side of the first clearance opening, and the first elastic element drives the limiting part to automatically reset to the first position, realizing the door closing operation. Since the limiting part is in the first position, it restricts the movement of the limiting post from the first side to the second side, thereby restricting the movement of the mating component and locking the door hook in the closed position, realizing the function of a child lock.

[0080] This design adds a step to opening the door, increasing the difficulty of opening it and reducing the risk of children being burned by heated food or utensils inside the cooking cavity due to accidental pressing or pulling of the door button or handle. This effectively avoids misoperation and thus improves the safety of using cooking appliances.

[0081] In one possible technical solution, the movement of the mating component causes the door hook to engage with the mating groove, so that when the door hook moves to the closed position, the limiting post can push the limiting component to move, so that the limiting post can move from the second side to the first side.

[0082] In this technical solution, when the door is in the closed state, the limiting member is in the first position and the limiting post is in the first side. At this time, since the limiting member is in the first position, the limiting post cannot move from the first side to the second side. That is, the limiting member blocks the movement path of the limiting post, which restricts the movement of the limiting post and thus restricts the movement of the mating parts so that the door hook is locked in the closed position.

[0083] When the transmission component slides relative to the fixed component, the transmission component pushes the limiting component to move from the first position to the second position. At this time, the limiting component avoids the movement path of the limiting post, and the limiting post can move from the first side to the second side, thereby realizing the door opening operation.

[0084] When the door is closed, the door hook pushes the mating component to rotate relative to the first bracket. At the same time, it drives the limiting post to move within the first clearance opening. During the movement of the limiting post, it pushes the limiting part to rotate relative to the second bracket and can be guided by the guide surface to the limiting post until the limiting part separates from the limiting post. The limiting post moves to the first side of the first clearance opening, and the first elastic element drives the limiting part to automatically reset to the first position, realizing the door closing operation. Since the limiting part is in the first position, it restricts the movement of the limiting post from the first side to the second side, thereby restricting the movement of the mating component and locking the door hook in the closed position, realizing the function of a child lock.

[0085] This design adds a step to opening the door, increasing the difficulty of opening it and reducing the risk of children being burned by heated food or utensils inside the cooking cavity due to accidental pressing or pulling of the door button or handle. This effectively avoids misoperation and thus improves the safety of using cooking appliances.

[0086] In one possible technical solution, the interlocking system further includes a limiting block, which is disposed on the second bracket and located on the second side of the first clearance opening. When the limiting member moves to the first position, the limiting block can prevent the limiting member from continuing to move.

[0087] In this technical solution, the interlocking system further includes a limiting block. Specifically, the limiting block is mounted on the second bracket and located on the second side of the first clearance opening. Specifically, when the limiting member moves to the first position, the limiting block can prevent the limiting member from continuing to move.

[0088] It is understandable that when the transmission component slides relative to the fixed component, it pushes the limiting component from the first position to the second position. At this time, the limiting post can move from the first side to the second side to realize the door opening process. After the door is opened, the transmission component is released, the first elastic component drives the limiting component to move from the second position to the first position, and the second elastic component drives the transmission component to reset.

[0089] When the door is closed, the limiting post pushes the limiting member to move until the limiting post and the limiting member separate. The limiting post moves from the second side to the first side, and the first elastic member drives the limiting member to move to the first position. When the limiting member moves to the first position, the limiting block can prevent the limiting member from moving further. Thus, by setting the limiting block, the limiting member can only move from the first position to the second position, or reset from the second position to the first position. In other words, when the limiting member moves to the first position, the limiting block prevents the limiting member from moving further, ensuring the stable operation of the door opening and closing process, avoiding the problem of the limiting member continuing to rotate and interfering with other components, and improving the reliability of cooking appliances with this interlocking system during the door opening and closing process.

[0090] In one possible technical solution, the interlocking system further includes a second support surface, which is located on the side of the second bracket near the limiting member. The limiting member has a first support surface, which is in contact with the second support surface and can move relative to the second support surface.

[0091] In this technical solution, the interlocking system is further defined as including a second support surface. Specifically, the second support surface is provided on the side of the second bracket near the limiting member. The limiting member is provided with a first support surface. The first support surface is in contact with the second support surface, and the first support surface can move relative to the second support surface, that is, the first support surface can move on the second support surface.

[0092] By setting a second support surface, the limiting component can be supported, preventing it from moving closer to the second support during rotation relative to it. This prevents the limiting component from wobbling, improves its stability and reliability during movement, and ensures the effective opening and closing of the door, thus enhancing the user experience of cooking appliances with this interlocking system.

[0093] In one possible technical solution, the interlocking system further includes a limiting wall, which is disposed on the second bracket and located on the first side of the first clearance opening. When the limiting member moves to the second position, it contacts the limiting wall.

[0094] In this technical solution, the interlocking system is further defined as including a limiting wall. Specifically, the limiting wall is set on the second bracket and located on the first side of the first clearance opening. When the limiting member moves to the second position, the limiting member contacts the limiting wall, thereby limiting the limiting member through the limiting wall and preventing the limiting member from continuing to rotate. Even if the limiting member can only rotate within a certain range, the problem of excessive rotation of the limiting member and interference with other components is further avoided, thereby improving the reliability of cooking appliances with this interlocking system during the opening and closing process.

[0095] In one possible technical solution, the second bracket is provided with a positioning post, a positioning groove and at least one first mounting hole; the interlocking system further includes a positioning hole, at least one second mounting hole and at least one fastener, wherein the positioning hole is provided on the fixing member, a part of the fixing member is embedded in the positioning groove, the positioning post passes through the positioning hole, at least one second mounting hole is provided on the fixing member, and the fastener passes through the first mounting hole and the second mounting hole respectively, so that the fixing member is connected to the second bracket.

[0096] In this technical solution, the interlocking system further includes a positioning hole, at least one second mounting hole, and at least one fastener. Specifically, the second bracket is provided with a positioning post, the positioning hole is located on the fastener, and the positioning post can pass through the positioning hole. The second bracket is also provided with a positioning groove, and a portion of the fastener can be embedded in the positioning groove, thereby further improving the installation stability and reliability of the fastener.

[0097] The second bracket is also provided with at least one first mounting hole, and the fastener is provided with at least one second mounting hole. The fastener passes through the first mounting hole and the second mounting hole respectively, thereby completing the fixed connection between the fastener and the second bracket.

[0098] It is worth noting that there can be multiple first mounting holes, and the number of second mounting holes and fasteners corresponds one-to-one with the number of first mounting holes. By setting multiple first mounting holes, second mounting holes and fasteners, the installation stability of the fasteners can be improved, thereby ensuring the reliability of the child lock structure.

[0099] In practical applications, the first and second mounting holes are threaded holes, and the fasteners are screws. The specific settings can be configured according to actual needs.

[0100] In one possible technical solution, the interlocking system also includes a buffer element connected to the mating element, used to reduce the rotational speed of the mating element when it rotates away from the door hook.

[0101] In this technical solution, the interlocking system also includes a buffer component. Specifically, the buffer component is connected to the mating component, and it slows down the rotational speed of the mating component as it rotates away from the door hook. Understandably, when the door is opened, the door hook pulls the mating component closer to the door hook; when the door is closed, the door hook pushes the mating component away from the door hook. In other words, the buffer component slows down the rotational speed of the mating component when the door is closed, thereby slowing down the closing speed of the door, reducing noise during closing, and improving the user experience.

[0102] In practical applications, buffer components include dampers.

[0103] The buffer is mounted on the first support and located within the accommodating cavity, thereby providing accommodating space for the buffer, protecting it, preventing external forces from acting directly on it, and extending its service life.

[0104] In addition, by placing the buffer inside the accommodating cavity, dirt and impurities can be reduced from entering the buffer, ensuring its cleanliness and thus ensuring the reliability of the interlocking system's various components.

[0105] In one possible technical solution, the mating part is provided with an adapter groove and an adapter portion, the adapter portion is located in the adapter groove, and the buffer part is connected to the mating part through the adapter portion.

[0106] In this technical solution, the mating parts are provided with a transition groove and a transition part. Specifically, the transition part is set in the transition groove, and the buffer is connected to the mating parts through the transition part. That is to say, the transition groove has the function of accommodating the transition part and connecting the transition part, in order to ensure the mating dimensions of the transition part and the buffer.

[0107] Specifically, the adapter and the adapter slot are detachably connected. This design reduces the processing difficulty of the product, facilitates mass production of the adapter, and helps reduce the production cost of the product. Because the adapter and the adapter slot are detachably connected, when the adapter is severely worn, the normal use of the product can be ensured by replacing the adapter, which helps reduce the cost of subsequent repair and maintenance.

[0108] According to a second aspect of the present invention, a cooking appliance is provided, including an interlocking system as provided by any of the above-described technical solutions, and thus possessing all the beneficial technical effects of the interlocking system, which will not be elaborated further here.

[0109] Furthermore, the cooking appliance also includes an appliance body and a door. The appliance body has a cooking cavity, and an interlocking system is provided on the appliance body and located at the opening end of the cooking cavity. The door is connected to the appliance body in an openable and closable manner, and the door includes a door hook.

[0110] The cooking appliance provided in this embodiment of the invention includes an appliance body, an interlocking system, and a door. Specifically, the appliance body is provided with a cooking cavity, the door is provided on the appliance body and the door can open or close the cooking cavity, and the interlocking system is provided on the appliance body and the interlocking system is located at the opening end of the cooking cavity. It can be understood that after the user opens the door, the food inside the cooking cavity can be taken out or put in through the opening end of the cooking cavity.

[0111] The door includes a door hook, which is fixed relative to the door. In other words, the door hook is a fixed hook, and the opening and closing of the door is achieved through the cooperation of the fixed door hook and its mating parts. It is worth noting that the door has an upper door hook and a lower door hook. Both the upper and lower door hooks can be fixed, or the lower door hook can be fixed while the upper door hook is movable; the specific configuration can be determined according to actual needs.

[0112] Microwave ovens in this technology allow users to open or close the cooking cavity by pulling or pressing the door to access food inside. However, because they lack child locks and the opening force is less than 25N, children can easily accidentally press the door button or pull the handle, opening the door with a light press or pull, resulting in burns from heated food or utensils inside the cooking cavity.

[0113] The limiting member can move between a first position and a second position, and the transmission mechanism can push the limiting member from the first position to the second position. Specifically, when the limiting member is in the first position, it can restrict the movement of the mating member. Since the limiting member restricts the movement of the mating member, and the mating groove of the mating member engages with the door hook, the door hook cannot move to the open position, even if the door hook is locked in the closed position. In other words, when the limiting member is in the first position, the door cannot be opened even if the door handle is pulled.

[0114] When the door needs to be opened, the transmission mechanism pushes the limiting member from the first position to the second position. When the limiting member is in the second position, it can release the movement restriction on the mating member. In other words, the mating member is unlocked. At this time, pulling the door handle will cause the door hook to move the mating member until the door hook slides out of the mating groove. The door hook then moves to the open position, thus opening the door.

[0115] By setting a limiting component that can move between a first position and a second position, when you want to open the door, you need to first have the transmission mechanism push the limiting component to the second position, thereby releasing the movement restriction on the mating parts, so that the door can be opened. This increases the steps to open the door, thus increasing the difficulty of opening the door. This reduces the risk of children accidentally touching the door opening button or handle, and being burned by the heated food or utensils inside the cooking cavity. It effectively avoids misoperation and thus effectively improves the safety of cooking appliances with this interlocking system.

[0116] In addition, the cooking appliance provided by the above-described technical solution of the present invention also has the following additional technical features:

[0117] In one possible technical solution, the cooking appliance also includes a control panel, which is located on the appliance body and has a second clearance opening. The trigger part of the interlocking system is exposed to the control panel through the second clearance opening.

[0118] In this technical solution, the cooking appliance is further defined as including a control panel. Specifically, the control panel is mounted on the appliance body and has a second clearance opening. The triggering part is exposed through the second clearance opening, allowing the user to use the triggering part to drive the first transmission part to move the limiting member, thereby releasing the movement restriction on the mating part. This reduces the difficulty of user operation and improves the user experience.

[0119] Furthermore, by setting a second clearance opening on the control panel, the triggering part can be operated. That is, only one clearance opening needs to be made on the control panel, which requires minimal modification to the cooking appliance and helps to reduce the production cost of the cooking appliance.

Detailed Implementation

[0209] 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.

[0210] 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.

[0211] The following reference Figures 1 to 85 To describe the interlocking system 100 and cooking appliance 400 provided according to some embodiments of the present invention.

[0212] Example 1:

[0213] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15, Figure 19 , Figure 20 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26 , Figure 27 , Figure 28 , Figure 29 , Figure 30 , Figure 31 , Figure 32 and Figure 33 As shown, an embodiment of the first aspect of the present invention provides an interlocking system 100 for cooperating with a door 410. The door 410 includes a door hook 411. The interlocking system 100 includes: a mating member 110, which has a mating groove 111. The movement of the mating member 110 enables the door hook 411 to engage with the mating groove 111, allowing the door hook 411 to move between an open position and a closed position; a limiting member 120, which is movable between a first position and a second position; and a transmission mechanism 130, which can push the limiting member 120 from the first position to the second position. Specifically, based on the limiting member 120 being in the first position, the limiting member 120 restricts the movement of the mating member 110, locking the door hook 411 in the closed position; based on the limiting member 120 being in the second position, the limiting member 120 releases the movement restriction on the mating member 110, allowing the door hook 411 to move to the open position.

[0214] The interlocking system 100 provided in this embodiment of the invention includes a mating component 110, a limiting component 120, and a transmission mechanism 130. Specifically, the mating component 110 is provided with a mating groove 111, which can engage with a door hook 411. Thus, when the mating component 110 moves, it can engage with the door hook 411 through the mating groove 111, allowing the door hook 411 to move between the open and closed positions. It is understood that the mating part 110 can move in opposite first and second directions. When the door 410 is closed, the user pushes the door 410, which drives the door hook 411 to move. When the door hook 411 moves to a certain position, it contacts the mating part 110 and pushes the mating part 110 to move. That is, during the closing process, the door hook 411 can push the mating part 110 to move in the first direction. The door hook 411 slides into the mating groove 111, so that the mating part 110 can pull the door hook 411 to the closed position during the movement, that is, the door 410 is in the closed position.

[0215] When the door 410 is opened, the user pulls the handle of the door 410, and the door 410 drives the door hook 411 to move. Since the door hook 411 is engaged with the mating groove 111, the door hook 411 drives the mating part 110 to move in the second direction during the opening process until the door hook 411 slides out of the mating groove 111 and the door 410 is in the open position.

[0216] In practical applications, the door hook 411 is fixed relative to the door body 410. That is, the door hook 411 is a fixed door hook, and the opening and closing operation of the door body 410 is achieved through the cooperation of the fixed door hook 411 with the mating groove 111. It is worth noting that the door body 410 is provided with an upper door hook 411 and a lower door hook 411. Both the upper and lower door hooks 411 can be fixed, or the lower door hook 411 can be fixed while the upper door hook 411 is movable; the specific configuration can be determined according to actual needs.

[0217] Microwave ovens in this technology allow users to open or close the cooking cavity by pulling or pressing the door to access food inside. However, because they lack child locks and the opening force is less than 25N, children can easily accidentally press the door button or pull the handle, opening the door with a light press or pull, resulting in burns from heated food or utensils inside the cooking cavity.

[0218] The limiting member 120 can move between a first position and a second position, and the transmission mechanism 130 can push the limiting member 120 from the first position to the second position. Specifically, when the limiting member 120 is in the first position, the limiting member 120 can restrict the movement of the mating member 110. Since the limiting member 120 restricts the movement of the mating member 110, and the mating groove 111 of the mating member 110 engages with the door hook 411, the door hook 411 cannot move to the open position, even if the door hook 411 is locked in the closed position. That is to say, when the limiting member 120 is in the first position, even if the handle of the door body 410 is pulled, the door body 410 cannot be opened.

[0219] When the door 410 needs to be opened, the transmission mechanism 130 pushes the limiting member 120 from the first position to the second position. When the limiting member 120 is in the second position, the limiting member 120 can release the movement restriction on the mating member 110. That is, the mating member 110 is unlocked. At this time, when the handle of the door 410 is pulled, the door hook 411 can drive the mating member 110 to move until the door hook 411 slides out of the mating groove 111. Then the door hook 411 moves to the open position, realizing the opening operation of the door 410.

[0220] By setting the limiting member 120 to move between a first position and a second position, when you want to open the door 410, you need to first make the transmission mechanism 130 push the limiting member 120 to the second position, thereby releasing the movement restriction on the mating member 110, so that the door can be opened. This increases the steps to open the door 410, thereby increasing the difficulty of opening the door 410. This reduces the risk of children being burned by the heated food or utensils in the cooking cavity due to accidentally touching the door opening button or handle and opening the oven door with a light press or pull. It effectively avoids misoperation and thus effectively improves the safety of using the cooking appliance 400 with this interlocking system 100.

[0221] It is understandable that a portion of the transmission mechanism 130 may be exposed outside the door body 410, thereby facilitating the user to unlock the mating part 110 by operating the portion of the transmission mechanism 130 exposed outside the door body 410, thus enabling the door body 410 to be opened.

[0222] The door 410 is equipped with a handle, which allows users to open the door by pulling the handle, thus improving user convenience.

[0223] It is worth noting that the mating part 110 is provided with a mating groove 111, and a part of the door hook 411 is constructed as a protrusion. During the opening and closing of the door, the protrusion can slide into or out of the mating groove 111.

[0224] Example 2:

[0225] like Figure 34 , Figure 35 , Figure 36 , Figure 37 , Figure 38 , Figure 39 , Figure 40 , Figure 41 , Figure 42 , Figure 43 , Figure 44 , Figure 45 , Figure 46 , Figure 47 , Figure 48 , Figure 49 , Figure 50 , Figure 51 , Figure 52 , Figure 53 , Figure 54 and Figure 55 As shown, based on the above embodiment, the transmission mechanism 130 further includes a fixing member 131 and a transmission member 132, wherein the transmission member 132 is disposed on the fixing member 131 and can slide relative to the fixing member 131, and the transmission member 132 can push the limiting member 120 to move from the first position to the second position.

[0226] In this embodiment, the transmission mechanism 130 is defined to include a fixing member 131 and a transmission member 132.

[0227] Specifically, the transmission member 132 is disposed on the fixed member 131, and the transmission member 132 is slidable relative to the fixed member 131. Thus, when the transmission member 132 is slidable relative to the fixed member 131, the transmission member 132 can push the limiting member 120 from the first position to the second position, so that the mating member 110 is unlocked.

[0228] In detail, when the limiting member 120 is in the first position, the limiting member 120 can restrict the movement of the mating member 110. Since the limiting member 120 restricts the movement of the mating member 110, and the mating groove 111 of the mating member 110 is engaged with the door hook 411, the door hook 411 cannot move to the open position. Even if the door hook 411 is locked in the closed position, that is, when the limiting member 120 is in the first position, even if the handle of the door body 410 is pulled, the door body 410 cannot be opened.

[0229] When the door 410 needs to be opened, the transmission member 132 slides relative to the fixed member 131, thereby causing the transmission member 132 to push the limiting member 120 from the first position to the second position. When the limiting member 120 is in the second position, the limiting member 120 can release the movement restriction on the mating member 110. That is, the mating member 110 is unlocked. At this time, when the handle of the door 410 is pulled, the door hook 411 can drive the mating member 110 to move until the door hook 411 slides out of the mating groove 111, so that the door hook 411 moves to the open position, realizing the opening operation of the door 410.

[0230] By setting the limiting member 120 to move between the first position and the second position, when you want to open the door 410, you need to first slide the transmission member 132 relative to the fixed member 131, and push the limiting member 120 to the second position during the sliding process, thereby releasing the movement restriction on the mating member 110, so that the door can be opened. This increases the steps to open the door 410, thereby increasing the difficulty of opening the door 410. This reduces the risk of children being burned by the heated food or utensils in the cooking cavity due to accidentally touching the door opening button or handle and opening the oven door with a light press or pull. It effectively avoids misoperation and thus effectively improves the safety of using the cooking appliance 400 with this interlocking system 100.

[0231] like Figure 9 , Figure 13 , Figure 38 , Figure 39 , Figure 40 , Figure 41 , Figure 44 and Figure 46As shown, based on the above embodiment, the fixing member 131 is further provided with a sliding channel 1311, and a part of the transmission member 132 passes through the sliding channel 1311 and can slide within the sliding channel 1311.

[0232] In this embodiment, the fixing member 131 is provided with a sliding channel 1311, a part of the transmission member 132 passes through the sliding channel 1311, and the transmission member 132 can slide within the sliding channel 1311, so that when the transmission member 132 moves, it can slide relative to the fixing member 131 within the sliding channel 1311, and then push the limiting member 120 to move during the sliding process, so that the mating member 110 is unlocked.

[0233] It is understandable that the sliding channel 1311 is a closed channel on all four sides, which limits the sliding trajectory of the transmission component 132 during the sliding process within the sliding channel 1311, ensuring the stability of the movement of the transmission component 132 within the sliding channel 1311, enabling the transmission component 132 to effectively push the limiting component 120 during the sliding process, thereby enabling the mating component 110 to be effectively unlocked, ensuring the stable operation of the door 410 opening and closing.

[0234] Example 3:

[0235] like Figure 6 , Figure 16 , Figure 17 , Figure 19 , Figure 21 , Figure 30 , Figure 32 , Figure 34 , Figure 35 , Figure 36 and Figure 37 As shown, based on any of the above embodiments, the interlocking system 100 further includes a first elastic member 140. The first end of the first elastic member 140 is connected to the fixing member 131, and the second end of the first elastic member 140 is connected to the limiting member 120. The first elastic member 140 is used to reset the limiting member 120 after it moves.

[0236] In this embodiment, the interlocking system 100 is further defined as including a first elastic member 140. Specifically, one end of the first elastic member 140 is connected to the fixing member 131 and the other end is connected to the limiting member 120. The first elastic member 140 can cause the limiting member 120 to reset after movement.

[0237] In detail, when the limiting member 120 is in the first position, the limiting member 120 can restrict the movement of the mating member 110. Since the limiting member 120 restricts the movement of the mating member 110, and the mating groove 111 of the mating member 110 is engaged with the door hook 411, the door hook 411 cannot move to the open position. Even if the door hook 411 is locked in the closed position, that is, when the limiting member 120 is in the first position, even if the handle of the door body 410 is pulled, the door body 410 cannot be opened.

[0238] When the door 410 needs to be opened, the transmission member 132 slides relative to the fixed member 131, thereby pushing the limiting member 120 from the first position to the second position. When the limiting member 120 is in the second position, it releases the restriction on the movement of the mating member 110. At this time, the first elastic member 140 undergoes elastic deformation, for example, it is stretched, meaning the mating member 110 is unlocked. Then, pulling the handle of the door 410 causes the door hook 411 to move the mating member 110 until it slides out of the mating groove 111, thus moving the door hook 411 to the open position and opening the door 410. After the door 410 is opened, the first elastic member 140 drives the limiting member 120 to move in the direction of the first position, i.e., the first elastic member 140 drives the limiting member 120 to move in the opposite direction to reset.

[0239] By setting the first elastic element 140, the limit element 120 can be automatically reset after movement, ensuring the effective operation of the door 410 opening and closing, improving the convenience of the user in using the cooking appliance 400 with the interlocking system 100, and thus enhancing the user experience.

[0240] In practical applications, the first elastic element 140 is a tension spring.

[0241] like Figure 21 , Figure 22 and Figure 23 As shown, based on the above embodiment, the interlocking system 100 further includes a second elastic member 150. The first end of the second elastic member 150 is connected to the fixing member 131, and the second end of the second elastic member 150 is connected to the transmission member 132. The second elastic member 150 is used to reset the transmission member 132 after it moves.

[0242] In this embodiment, the interlocking system 100 further includes a second elastic member 150. Specifically, one end of the second elastic member 150 is connected to the fixing member 131, and the other end is connected to the transmission member 132. The second elastic member 150 can cause the transmission member 132 to move and then reset. That is, when the transmission member 132 slides relative to the fixing member 131, so that the transmission member 132 pushes the limiting member 120 to the second position, thereby unlocking the mating member 110 and opening the door 410, the second elastic member 150 can drive the transmission member 132 to slide and reset in the opposite direction. So that when the door 410 is closed and needs to be opened again, the mating member 110 can be unlocked by the movement of the transmission member 132.

[0243] By setting the second elastic element 150, the transmission element 132 can be automatically reset after movement, which improves the convenience for users to use the cooking appliance 400 with the interlocking system 100, thereby enhancing the user experience.

[0244] Furthermore, when the transmission component 132 moves and pushes the limiting component 120 to the second position, thereby unlocking the mating component 110, the first elastic component 140 drives the limiting component 120 to automatically reset, and the second elastic component 150 drives the transmission component 132 to automatically reset. This means that the reset processes of the transmission component 132 and the limiting component 120 are performed separately, reducing the collision and wear that occur between the limiting component 120 and the transmission component 132 during the reset process, thereby extending the service life of the transmission component 132 and the limiting component 120.

[0245] Furthermore, by setting the first elastic element 140 and the second elastic element 150, the driving force that moves the transmission element 132 can be increased, further increasing the difficulty of opening the door and further reducing the risk of children being burned by the heated food or utensils inside the cooking cavity due to accidentally touching the door opening button or handle and lightly pressing or pulling to open the oven door. This effectively avoids misoperation and further improves the safety of using the cooking appliance 400 with the interlocking system 100.

[0246] In practical applications, the second elastic element 150 is a tension spring.

[0247] Example 4:

[0248] like Figure 49 , Figure 50 , Figure 51 , Figure 52 , Figure 53 , Figure 54 and Figure 55 As shown, based on the above embodiment, the transmission member 132 further includes a trigger part 1321 and a first transmission part 1322, wherein the first transmission part 1322 is disposed on the trigger part 1321, and the first transmission part 1322 is used to push the limiting member 120 from the first position to the second position.

[0249] In this embodiment, the transmission member 132 is defined to include a trigger part 1321 and a first transmission part 1322. Specifically, the first transmission part 1322 is disposed on the trigger part 1321. When the trigger part 1321 is triggered, the trigger part 1321 can drive the first transmission part 1322 to slide relative to the fixed member 131. During the sliding process, the first transmission part 1322 pushes the limiting member 120 to move to the second position to release the movement restriction on the mating member 110.

[0250] In detail, when the limiting member 120 is in the first position, the limiting member 120 can restrict the movement of the mating member 110. Since the limiting member 120 restricts the movement of the mating member 110, and the mating groove 111 of the mating member 110 is engaged with the door hook 411, the door hook 411 cannot move to the open position. Even if the door hook 411 is locked in the closed position, that is, when the limiting member 120 is in the first position, even if the handle of the door body 410 is pulled, the door body 410 cannot be opened.

[0251] When the door 410 needs to be opened, the trigger 1321 is triggered. When the trigger 1321 is triggered, it drives the first transmission part 1322 to slide relative to the fixed member 131. During the sliding process, the first transmission part 1322 pushes the limiting member 120 from the first position to the second position. When the limiting member 120 is in the second position, it can release the movement restriction on the mating member 110. At this time, the first elastic member 140 and the second elastic member 150 undergo elastic deformation. For example, both the first elastic member 140 and the second elastic member 150 are stretched. At this time, when the handle of the door 410 is pulled, the door hook 411 can drive the mating member 110 to move until the door hook 411 slides out of the mating groove 111, so that the door hook 411 moves to the open position, realizing the opening operation of the door 410.

[0252] When the door 410 is opened, the trigger part 1321 is released. The first elastic element 140 drives the limiting element 120 to move in the direction of the first position, and the second elastic element 150 drives the transmission element 132 to move in the opposite direction and reset.

[0253] In practical applications, the trigger part 1321 and the first transmission part 1322 are an integral structure. It is understood that the integral structure has good mechanical properties, which can improve the connection strength between the trigger part 1321 and the first transmission part 1322 and ensure effective power transmission.

[0254] In addition, the integrated structure facilitates the processing and production of the transmission component 132, thereby reducing the production cost of the interlocking system 100 and the cooking appliance 400 having the interlocking system 100.

[0255] like Figure 6, Figure 7 , Figure 20 , Figure 24 , Figure 25 , Figure 26 , Figure 34 , Figure 37 , Figure 49 , Figure 50 , Figure 51 , Figure 52 , Figure 53 , Figure 54 and Figure 55 As shown, based on the above embodiment, the transmission member 132 further includes a stop portion 1323, which is provided at one end of the trigger portion 1321. When the transmission member 132 moves away from the limiting member 120, the stop portion 1323 can abut against the fixing member 131.

[0256] In this embodiment, the transmission member 132 is further defined as including a stop portion 1323. Specifically, the stop portion 1323 is disposed on one end of the trigger portion 1321. When the transmission member 132 moves away from the limiting member 120, the stop portion 1323 can abut against the fixing member 131 to prevent the trigger portion 1321 from moving excessively and to ensure the effective operation of the door opening and closing process of the interlocking system 100.

[0257] In detail, when the trigger 1321 is triggered, the actuating part drives the first transmission part 1322 and the stop part 1323 to slide relative to the fixed member 131, so that the first transmission part 1322 pushes the limiting member 120 to the second position, thereby unlocking the mating member 110. After the door opening operation is completed, the trigger 1321 is released, and the first elastic member 140 drives the limiting member 120 to move in the direction of the first position. During the process of the second elastic member 150 driving the transmission member 132 to move in the opposite direction to reset, when it moves to a certain position, the stop part 1323 abuts against the fixed member 131, thereby completing the reset of the transmission member 132. That is, the stop part 1323 limits the reset process of the transmission member 132, preventing the transmission member 132 from moving excessively, thereby ensuring the effective operation of the door opening and closing process and improving the stability and reliability of the opening and closing process of the cooking appliance 400 with this interlocking system 100.

[0258] In practical applications, the stop part 1323 and the trigger part 1321 are an integral structure. It is understood that the integral structure has good mechanical properties, which can improve the connection strength between the stop part 1323 and the trigger part 1321, ensure effective power transmission, and at the same time, ensure the effective limiting of the stop part 1323 when the trigger part 1321 is reset.

[0259] It is understood that a portion of the trigger 1321 may be exposed outside the door 410, thereby facilitating the user to drive the transmission component 132 to move by operating the trigger 1321. The stop 1323 is located at the end of the trigger 1321 opposite to the portion of the trigger 1321 exposed outside the door 410.

[0260] In addition, the integrated structure facilitates the processing and production of the transmission component 132, thereby reducing the production cost of the interlocking system 100 and the cooking appliance 400 having the interlocking system 100.

[0261] like Figure 4 , Figure 7 , Figure 13 , Figure 20 , Figure 34 , Figure 35 , Figure 36 , Figure 37 , Figure 38 , Figure 39 , Figure 40 , Figure 41 , Figure 46 , Figure 47 , Figure 49 , Figure 50 , Figure 52 , Figure 53 and Figure 54 As shown, based on the above embodiment, the fixing member 131 is further provided with a first support portion 1312; the interlocking system 100 also includes a second support portion 1324, which is disposed on the transmission member 132, and is located on the first support portion 1312 and can slide relative to the first support portion 1312.

[0262] In this embodiment, the interlocking system 100 is further defined as including a second support portion 1324. Specifically, the fixing member 131 is provided with a first support portion 1312, and the second support portion 1324 is provided on the transmission member 132. Specifically, the second support portion 1324 is provided on the trigger portion 1321, and the second support portion 1324 is located on the first support portion 1312 and can slide relative to the first support portion 1312.

[0263] In other words, the second support part 1324 is located above the first support part 1312, and during the process of the trigger part 1321 being triggered and driving the first transmission part 1322 to slide relative to the fixed member 131, or the second elastic member 150 driving the transmission part 132 to reset, the second support part 1324 can slide on the first support part 1312. Thus, while realizing the effective opening and closing process, the cooperation and support between the first support part 1312 and the second support part 1324 further improves the stability and reliability of the transmission part 132 when sliding relative to the fixed member 131, prevents the transmission part 132 from shaking when sliding relative to the fixed member 131, and ensures that the first transmission part 1322 can push the limiting member 120 to the second position during the sliding process to unlock the cooperating member 110, thereby completing the door opening operation.

[0264] In addition, the fastener 131 is used for the fixed connection of the transmission mechanism 130, and the second support part 1324 connected to the transmission part 132 is located on the first support part 1312, so that the first support part 1312 can support the second support part 1324, thereby improving the installation stability of the transmission part 132.

[0265] In practical applications, the second support part 1324 and the trigger part 1321 are an integral structure.

[0266] Example 5:

[0267] like Figure 28 , Figure 33 , Figure 34 , Figure 35 , Figure 36 , Figure 56 , Figure 57 , Figure 58 , Figure 59 , Figure 60 and Figure 61 As shown, based on any of the above embodiments, the limiting member 120 further includes a second transmission part 123, a connecting part 121, and a limiting part 122. The first transmission part 122 can drive the second transmission part 123 to move. The connecting part 121 is connected to the second transmission part 123, and the limiting part 122 is connected to the connecting part 121. Based on the limiting member 120 being located in the first position, the limiting part 122 restricts the movement of the mating part 110. The movement of the second transmission part 123 can drive the limiting part 122 to move from the first position to the second position through the connecting part 121.

[0268] In this embodiment, the limiting member 120 is defined to include a second transmission part 123, a connecting part 121 and a limiting part 122. Specifically, the limiting part 122 is connected to the connecting part 121, and the second transmission part 123 is connected to the connecting part 121.

[0269] In detail, when the limiting member 120 is in the first position, the limiting part 122 can restrict the movement of the mating member 110. Since the limiting part 122 restricts the movement of the mating member 110, and the mating groove 111 of the mating member 110 is engaged with the door hook 411, the door hook 411 cannot move to the open position. Even if the door hook 411 is locked in the closed position, that is, when the limiting member 120 is in the first position, even if the handle of the door body 410 is pulled, the door body 410 cannot be opened.

[0270] When the door 410 needs to be opened, the trigger 1321 is triggered. When the trigger 1321 is triggered, it drives the first transmission part 1322 to slide relative to the fixed part 131. During the sliding process, the first transmission part 1322 pushes the second transmission part 123 to move. The movement of the second transmission part 123 drives the connecting part 121 to move. The movement of the connecting part 121 then drives the limiting part 122 to move from the first position to the second position. When the limiting part 122 is in the second position, it can release the movement restriction on the mating part 110. At this time, the first elastic member 140 and the second elastic member 150 undergo elastic deformation. For example, both the first elastic member 140 and the second elastic member 150 are stretched. At this time, when the handle of the door 410 is pulled, the door hook 411 can drive the mating part 110 to move until the door hook 411 slides out of the mating groove 111, so that the door hook 411 moves to the open position, realizing the opening operation of the door 410.

[0271] Furthermore, when the door 410 is opened, the trigger part 1321 is released, the first elastic element 140 drives the limiting element 120 to move in the direction of the first position, and the second elastic element 150 drives the transmission element 132 to move in the opposite direction and reset.

[0272] In practical applications, the limiting part 122, the connecting part 121 and the second transmission part 123 are integrated into one structure. It is understood that the integrated structure has good mechanical properties, which can improve the connection strength between the limiting part 122, the connecting part 121 and the second transmission part 123 and ensure effective power transmission.

[0273] In addition, the integrated structure facilitates the processing and production of the limiting component 120, thereby reducing the production cost of the interlocking system 100 and the cooking appliance 400 having the interlocking system 100.

[0274] like Figure 35 , Figure 36 , Figure 56 , Figure 58 , Figure 59 and Figure 60As shown, based on the above embodiment, the limiting part 122 is further provided with a guide surface 124. When the mating part 110 moves, the door hook 411 engages with the mating groove 111, so that during the process of the door hook 411 moving to the closed position, the guide surface 124 can guide a part of the mating part 110.

[0275] In this embodiment, the limiting part 122 is provided with a guide surface 124. Specifically, when the mating part 110 moves to make the door hook 411 engage with the mating groove 111, and the door hook 411 moves to the closed position, the guide surface 124 can guide a part of the mating part 110, thereby ensuring the smooth closing process.

[0276] Specifically, when the limiting part 122 is in the first position, it can restrict the movement of a portion of the mating member 110, that is, the limiting part 122 is located on the movement path of a portion of the mating member 110, thereby restricting the movement of the mating member 110 and locking the door hook 411 in the closed position. When it is necessary to open the door, the transmission member 132 slides relative to the fixed member 131 and pushes the second transmission member 123 through the first transmission member 1322, thereby causing the limiting part 122 to move to the second position, so that the limiting part 122 avoids the movement path of a portion of the mating member 110. At this time, a portion of the mating member 110 can move on the movement path to complete the door opening operation.

[0277] During the closing process, a portion of the mating member 110 pushes the limiting part 122 to move along the movement path. At this time, the first elastic member 140 is stretched. When the portion of the mating member 110 separates from the limiting part 122, the portion of the mating member 110 moves into place, completing the closing operation. The first elastic member 140 drives the limiting part 122 to return to the first position, that is, the limiting part 122 is on the movement path of the portion of the mating member 110, thereby restricting the movement of the mating member 110 and realizing the child lock function.

[0278] During the process of closing the door, the guide surface 124 can guide the movement of a portion of the mating part 110 to the limit part 122 along the movement path.

[0279] In practical applications, the mating part 110 includes a limiting post 112, and the guide surface 124 can guide the movement of the limiting post 112 on the movement path to complete the door closing operation.

[0280] Example 6:

[0281] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26 , Figure 27 , Figure 28 , Figure 29 , Figure 30 , Figure 31 , Figure 32 , Figure 33 , Figure 65 , Figure 66 , Figure 67 , Figure 68 , Figure 69 , Figure 70 , Figure 71 , Figure 72 , Figure 73 , Figure 74 , Figure 75 , Figure 76 , Figure 77 , Figure 78 , Figure 79 , Figure 80 , Figure 81 , Figure 82 , Figure 83 and Figure 84 As shown, based on any of the above embodiments, the interlocking system 100 further includes a first bracket 160 and a second bracket 170, wherein the mating member 110 is rotatably disposed on the first bracket 160, the second bracket 170 is connected to the first bracket 160 and surrounds to form a receiving cavity, a part of the mating member 110 is located in the receiving cavity, and the limiting member 120 is rotatably disposed on the side of the second bracket 170 away from the receiving cavity.

[0282] In this embodiment, the interlocking system 100 further includes a first bracket 160 and a second bracket 170. Specifically, the first bracket 160 is connected to the second bracket 170, and the first bracket 160 and the second bracket 170 together form a receiving cavity, that is, the side of the first bracket 160 near the second bracket 170 and the side of the second bracket 170 near the first bracket 160 form the receiving cavity. The mating component 110 is located within the receiving cavity, meaning that the receiving cavity provides installation space for the mating component 110. This protects the mating component 110, prevents external forces from directly acting on it, and thus extends the service life of the mating component 110.

[0283] Furthermore, by placing a portion of the mating part 110 within the receiving cavity, dirt and impurities can be reduced from entering the mating part 110, ensuring the cleanliness of the mating part 110 and thus ensuring the reliability of the mating of each component of the interlocking system 100.

[0284] The mating part 110 is disposed on the first bracket 160 and can rotate relative to the first bracket 160. That is, during the opening and closing of the door, the door hook 411 engages with the mating groove 111 of the mating part 110, thereby causing the mating part 110 to rotate relative to the first bracket 160 to complete the opening and closing operation.

[0285] The limiting member 120 is disposed on the side of the second bracket 170 away from the receiving cavity, and the limiting member 120 can rotate relative to the second bracket 170. When the transmission member 132 slides relative to the fixed member 131, the transmission member 132 can push the limiting member 120 to rotate from the first position to the second position, thereby releasing the movement restriction on the mating member 110. By pulling the door body 410, the door can be opened through the cooperation of the door hook 411 and the mating member 110.

[0286] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 14 , Figure 15 , Figure 17 , Figure 18 , Figure 22 , Figure 23 , Figure 28 , Figure 30 , Figure 31 , Figure 33 , Figure 65 , Figure 66 , Figure 67 , Figure 79 , Figure 80 , Figure 81 and Figure 83 As shown, based on the above embodiment, the mating member 110 is further provided with a limiting post 112; the interlocking system 100 also includes a first clearance opening 180, the first clearance opening 180 is provided on the second bracket 170, the limiting post 112 extends out of the second bracket 170 through the first clearance opening 180 and can move within the first clearance opening 180; wherein, based on the limiting member 120 being located in the first position, the limiting post 112 is located on the first side 181 of the first clearance opening 180, the limiting member 120 prevents the limiting post 112 from moving from the first side 181 to the second side 182 of the first clearance opening 180; based on the limiting member 120 being located in the second position, the limiting post 112 can move from the first side 181 to the second side 182.

[0287] In this embodiment, the interlocking system 100 is further defined as including a first clearance opening 180. Specifically, the first clearance opening 180 is disposed on the second bracket 170, and the mating part 110 is provided with a limiting post 112. The limiting post 112 extends out of the second bracket 170 through the first clearance opening 180. That is to say, the first clearance opening 180 is in communication with the receiving cavity.

[0288] During the opening and closing of the door, the limiting post 112 can move within the first clearance opening 180. The second bracket 170 includes a first side 181 and a second side 182 located in the first clearance opening 180 and disposed opposite to each other. It is understood that when the limiting post 112 is located on the first side, the door 410 is closed, and when the limiting post 112 moves from the first side 181 to the second side 182, the door 410 is opened.

[0289] In detail, when the door 410 is in the closed state, the limiting member 120 is in the first position and the limiting post 112 is in the first side 181. At this time, since the limiting member 120 is in the first position, the limiting post 112 cannot move from the first side 181 to the second side 182. That is, the limiting member 120 blocks the movement path of the limiting post 112, thus restricting the movement of the limiting post 112, thereby restricting the movement of the mating member 110, so that the door hook 411 is locked in the closed position.

[0290] When the transmission component 132 slides relative to the fixed component 131, the transmission component 132 pushes the limiting component 120 from the first position to the second position. At this time, the limiting component 120 avoids the movement path of the limiting post 112, and the limiting post 112 can move from the first side 181 to the second side 182, thereby realizing the door opening operation.

[0291] When the door 410 is closed, the door hook 411 pushes the mating part 110 to rotate relative to the first bracket 160. At the same time, it drives the limiting post 112 to move within the first clearance opening 180. During the movement of the limiting post 112, it pushes the limiting part 122 to rotate relative to the second bracket 170. The limiting post 112 is guided by the guide surface 124 until the limiting part 122 separates from the limiting post 112. The limiting post 112 moves to the first side 181 of the first clearance opening 180. The first elastic member 140 drives the limiting part 120 to automatically reset to the first position, realizing the door closing operation. Since the limiting part 120 is in the first position, it restricts the movement of the limiting post 112 from the first side 181 to the second side 182, thereby restricting the movement of the mating part 110 and locking the door hook 411 in the closed position, realizing the function of a child lock.

[0292] This adds a step to opening the door 410, increasing the difficulty of opening the door 410. This reduces the risk of children accidentally touching the door opening button or handle, which could easily open the oven door with a light press or pull, resulting in burns from the heated food or utensils inside the cooking cavity. It effectively avoids misoperation and thus effectively improves the safety of using the cooking appliance 400.

[0293] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 14 , Figure 15 , Figure 17 , Figure 18 , Figure 22 , Figure 23 , Figure 28 , Figure 30 , Figure 31 , Figure 33 , Figure 65 , Figure 66 , Figure 67 , Figure 79 , Figure 80 , Figure 81 and Figure 83 As shown, based on any of the above embodiments, the mating member 110 moves to engage the door hook 411 with the mating groove 111, so that when the door hook 411 moves to the closed position, the limiting post 112 can push the limiting member 120 to move, so that the limiting post 112 can move from the second side 182 to the first side 181.

[0294] In this embodiment, when the door 410 is in the closed state, the limiting member 120 is in the first position and the limiting post 112 is in the first side 181. At this time, since the limiting member 120 is in the first position, the limiting post 112 cannot move from the first side 181 to the second side 182. That is, the limiting member 120 blocks the movement path of the limiting post 112, thereby restricting the movement of the limiting post 112 and thus restricting the movement of the mating member 110 so that the door hook 411 is locked in the closed position.

[0295] When the transmission component 132 slides relative to the fixed component 131, the transmission component 132 pushes the limiting component 120 from the first position to the second position. At this time, the limiting component 120 avoids the movement path of the limiting post 112, and the limiting post 112 can move from the first side 181 to the second side 182, thereby realizing the door opening operation.

[0296] When the door 410 is closed, the door hook 411 pushes the mating part 110 to rotate relative to the first bracket 160. At the same time, it drives the limiting post 112 to move within the first clearance opening 180. During the movement of the limiting post 112, it pushes the limiting part 122 to rotate relative to the second bracket 170. The limiting post 112 is guided by the guide surface 124 until the limiting part 122 separates from the limiting post 112. The limiting post 112 moves to the first side 181 of the first clearance opening 180. The first elastic member 140 drives the limiting part 120 to automatically reset to the first position, realizing the door closing operation. Since the limiting part 120 is in the first position, it restricts the movement of the limiting post 112 from the first side 181 to the second side 182, thereby restricting the movement of the mating part 110 and locking the door hook 411 in the closed position, realizing the function of a child lock.

[0297] This adds a step to opening the door 410, increasing the difficulty of opening the door 410. This reduces the risk of children accidentally touching the door opening button or handle, which could easily open the oven door with a light press or pull, resulting in burns from the heated food or utensils inside the cooking cavity. It effectively avoids misoperation and thus effectively improves the safety of using the cooking appliance 400.

[0298] Example 7:

[0299] like Figure 2 , Figure 3 , Figure 6 , Figure 9 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 19 , Figure 21 , Figure 24 , Figure 25 , Figure 26 , Figure 28 , Figure 30, Figure 31 , Figure 33 , Figure 65 , Figure 66 , Figure 67 , Figure 75 , Figure 76 and Figure 77 As shown, based on any of the above embodiments, the interlocking system 100 further includes a limiting block 210. The limiting block 210 is disposed on the second bracket 170 and located on the second side 182 of the first clearance opening 180. When the limiting member 120 moves to the first position, the limiting block 210 can prevent the limiting member 120 from continuing to move.

[0300] In this embodiment, the interlocking system 100 further includes a limiting block 210. Specifically, the limiting block 210 is disposed on the second bracket 170 and located on the second side 182 of the first clearance opening 180. Specifically, when the limiting member 120 moves to the first position, the limiting block 210 can prevent the limiting member 120 from continuing to move.

[0301] It is understandable that when the transmission member 132 slides relative to the fixed member 131, the transmission member 132 pushes the limiting member 120 from the first position to the second position. At this time, the limiting post 112 can move from the first side 181 to the second side 182 to realize the opening process of the door 410. After the door 410 is opened, the transmission member 132 is released, the first elastic member 140 drives the limiting member 120 to move from the second position to the first position, and the second elastic member 150 drives the transmission member 132 to reset.

[0302] When the door is closed, the limiting post 112 pushes the limiting member 120 to move until the limiting post 112 separates from the limiting member 120. The limiting post 112 moves from the second side 182 to the first side 181. The first elastic member 140 drives the limiting member 120 to move to the first position. When the limiting member 120 moves to the first position, the limiting block 210 can prevent the limiting member 120 from continuing to move. Thus, by setting the limiting block 210, the limiting member 120 can only move from the first position to the second position, or reset from the second position to the first position. In other words, when the limiting member 120 moves to the first position, due to the action of the limiting block 210, the limiting member 120 cannot continue to move, ensuring the stable operation of the door opening and closing process, avoiding the problem of the limiting member 120 continuing to rotate and interfering with other components, and improving the reliability of the cooking appliance 400 with this interlocking system 100 in the door opening and closing process.

[0303] like Figure 2 , Figure 3 , Figure 14 , Figure 15 , Figure 17 , Figure 18 , Figure 20 , Figure 22 , Figure 35 , Figure 56 , Figure 57 , Figure 59 , Figure 65 , Figure 66 , Figure 67 , Figure 76 and Figure 83 As shown, based on any of the above embodiments, the interlocking system 100 further includes a second support surface 220. The second support surface 220 is disposed on the side of the second bracket 170 near the limiting member 120. The limiting member 120 is provided with a first support surface 125. The first support surface 125 is in contact with the second support surface 220 and can move relative to the second support surface 220.

[0304] In this embodiment, the interlocking system 100 is further defined as including a second support surface 220. Specifically, the second support surface 220 is disposed on the side of the second bracket 170 near the limiting member 120. The limiting member 120 is provided with a first support surface 125. The first support surface 125 is in contact with the second support surface 220, and the first support surface 125 is movable relative to the second support surface 220, that is, the first support surface 125 is movable on the second support surface 220.

[0305] By setting the second support surface 220, the limiting member 120 can be supported, preventing the limiting member 120 from moving towards the second support 170 during rotation relative to the second support 170, thus preventing the limiting member 120 from shaking, improving the stability and reliability of the limiting member 120 during movement, thereby ensuring the effective operation of the door opening and closing process, and enhancing the user's experience of using the cooking appliance 400 with the interlocking system 100.

[0306] Example 8:

[0307] like Figure 3 , Figure 4 , Figure 12 , Figure 20 , Figure 25 , Figure 26 , Figure 65 , Figure 66 and Figure 67 As shown, based on any of the above embodiments, the interlocking system 100 further includes a limiting wall 230, which is disposed on the second bracket 170 and located on the first side 181 of the first clearance opening 180. When the limiting member 120 moves to the second position, it contacts the limiting wall 230.

[0308] In this embodiment, the interlocking system 100 further includes a limiting wall 230. Specifically, the limiting wall 230 is disposed on the second bracket 170 and located on the first side 181 of the first clearance opening 180. When the limiting member 120 moves to the second position, the limiting member 120 contacts the limiting wall 230, thereby limiting the limiting member 120 by the limiting wall 230 and preventing the limiting member 120 from continuing to rotate. Even if the limiting member 120 can only rotate within a certain range, the problem of excessive rotation of the limiting member 120 and interference with other components is further avoided, thereby improving the reliability of the cooking appliance 400 with the interlocking system 100 during the opening and closing process.

[0309] like Figure 2 , Figure 3 , Figure 12 , Figure 14 , Figure 35 , Figure 37 , Figure 38 , Figure 39 , Figure 42 , Figure 44 , Figure 45 , Figure 46 , Figure 47 and Figure 48 As shown, based on any of the above embodiments, the second bracket 170 is further provided with a positioning post 171, a positioning groove 172 and at least one first mounting hole 173; the interlocking system 100 also includes a positioning hole 240, at least one second mounting hole 250 and at least one fastener, wherein the positioning hole 240 is provided on the fixing member 131, a part of the fixing member 131 is embedded in the positioning groove 172, the positioning post 171 passes through the positioning hole 240, at least one second mounting hole 250 is provided on the fixing member 131, and the fastener passes through the first mounting hole 173 and the second mounting hole 250 respectively, so that the fixing member 131 is connected to the second bracket 170.

[0310] In this embodiment, the interlocking system 100 further includes a positioning hole 240, at least one second mounting hole 250, and at least one fastener. Specifically, a positioning post 171 is provided on the second bracket 170, the positioning hole 240 is provided on the fastener 131, and the positioning post 171 can pass through the positioning hole 240. A positioning groove 172 is also provided on the second bracket 170, and a portion of the fastener 131 can be embedded in the positioning groove 172, thereby further improving the installation stability and reliability of the fastener 131.

[0311] The second bracket 170 is also provided with at least one first mounting hole 173, and the fastener 131 is provided with at least one second mounting hole 250. The fasteners pass through the first mounting hole 173 and the second mounting hole 250 respectively, thereby completing the fixed connection between the fastener 131 and the second bracket 170.

[0312] It is worth noting that there can be multiple first mounting holes 173, and the number of second mounting holes 250 and fasteners corresponds one-to-one with the number of first mounting holes 173. By setting multiple first mounting holes 173, second mounting holes 250 and fasteners, the installation stability of the fastener 131 can be improved, thereby ensuring the reliability of the child lock structure.

[0313] In practical applications, the first mounting hole 173 and the second mounting hole 250 are threaded holes, and the fasteners are screws. The specific settings can be configured according to actual needs.

[0314] Example 9:

[0315] like Figure 29 , Figure 71 and Figure 72 As shown, based on any of the above embodiments, the interlocking system 100 further includes a buffer 260, which is connected to the mating member 110 and is used to reduce the rotational speed of the mating member 110 when it rotates away from the door hook 411.

[0316] In this embodiment, the interlocking system 100 further includes a buffer 260. Specifically, the buffer 260 is connected to the mating member 110, and the buffer 260 can slow down the rotational speed of the mating member 110 when it rotates away from the door hook 411. It is understood that when the door 410 is opened, the door hook 411 pulls the mating member 110 towards the door hook 411; when the door 410 is closed, the door hook 411 pushes the mating member 110 away from the door hook 411. In other words, the buffer 260 can slow down the rotational speed of the mating member 110 when the door is closed, thereby slowing down the closing speed of the door 410, reducing noise generated during closing, and improving the user experience.

[0317] In practical applications, the buffer 260 includes a damper.

[0318] The buffer 260 is disposed on the first bracket 160 and is located in the accommodating cavity, thereby providing accommodating space for the buffer 260, protecting the buffer 260, preventing external forces from acting directly on the buffer 260, and thus extending the service life of the buffer 260.

[0319] In addition, by placing the buffer 260 inside the accommodating cavity, dirt and impurities can be reduced from entering the buffer 260, ensuring the cleanliness of the buffer 260 and thus ensuring the reliability of the cooperation of each component of the interlocking system 100.

[0320] like Figure 29 , Figure 71 and Figure 72As shown, based on the above embodiment, the mating member 110 is further provided with a transition groove 280 and a transition part 270. The transition part 270 is located in the transition groove 280, and the buffer member 260 is connected to the mating member 110 through the transition part 270.

[0321] In this embodiment, the mating member 110 is provided with a transition groove 280 and a transition part 270. Specifically, the transition part 270 is disposed in the transition groove 280, and the buffer member 260 is connected to the mating member 110 through the transition part 270. That is to say, the transition groove 280 has the function of accommodating the transition part 270 and connecting the transition part 270, in order to ensure the mating dimensions of the transition part 270 and the buffer member 260.

[0322] Specifically, the adapter 270 and the adapter slot 280 are detachably connected. This design reduces the processing difficulty of the product, facilitates mass production of the adapter 270, and helps reduce the production cost of the product. Since the adapter 270 and the adapter slot 280 are detachably connected, when the adapter 270 is severely worn, the normal use of the product can be ensured by replacing the adapter 270, which helps reduce the cost of subsequent repair and maintenance.

[0323] like Figure 29 , Figure 62 , Figure 63 and Figure 64 As shown, based on any of the above embodiments, the mating component 110 further includes a mating body, a first mating arm 113, and a second mating arm 114.

[0324] The first mating arm 113 is connected to the mating body, the second mating arm 114 is connected to the mating body, and forms a mating groove 111 with the first mating arm 113 at a distance. A part of the door hook 411 can be located in the mating groove 111 so that the mating part 110 can mate with the door hook 411.

[0325] In this embodiment, the mating component 110 is defined as including a mating body, a first mating arm 113 and a second mating arm 114. Specifically, the first mating arm 113 and the second mating arm 114 are connected to the mating body and are spaced apart. The first mating arm 113 and the second mating arm 114 form a mating groove 111. A portion of the door hook 411 can be located in the mating groove 111 so that the mating component 110 can mate with the door hook 411.

[0326] In detail, when closing the door 410, the user pushes the door 410, causing the door hook 411 to move. After the door hook 411 moves to a certain position, it contacts the first mating arm 113 and pushes the first mating arm 113 to rotate relative to the first bracket 160. At the same time, the first mating arm 113 drives the mating body and the second mating arm 114 to rotate. During the process of pushing the first mating arm 113, a part of the door hook 411 slides into the mating groove 111, so that the mating part 110 can pull the door hook 411 to the closed position during rotation, that is, the door 410 is in the closed position.

[0327] When the door 410 is opened, the user pulls the handle, causing the door 410 to move the door hook 411. Since a portion of the door hook 411 is located within the mating groove 111, during the opening process, the door hook 411 drives the mating component 110 to rotate. As the mating component 110 rotates, it pushes the door hook 411 until a portion of the door hook 411 moves out of the mating groove 111, thus placing the door 410 in the open position. The mating groove 111 ensures effective engagement between the door hook 411 and the mating component 110.

[0328] The limiting post 112 is set on the mating body, so that when the mating body rotates relative to the first bracket 160, it can drive the limiting post 112 to move within the first clearance opening 180.

[0329] like Figure 30 , Figure 32 , Figure 71 , Figure 72 , Figure 73 , Figure 74 and Figure 84 As shown, based on the above embodiments, the interlocking system 100 further includes a third elastic element 290, which is connected to the first bracket 160 and the mating element 110.

[0330] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 12 , Figure 15 , Figure 21 , Figure 22 , Figure 23 , Figure 25 , Figure 26 , Figure 28 , Figure 62 , Figure 63 , Figure 64 , Figure 71 and Figure 72As shown, based on the above embodiment, the interlocking system 100 further includes a protrusion 115 and a first switch 310. The protrusion 115 is provided on the mating member 110, and a third clearance opening is provided on the second bracket 170. The protrusion 115 extends out of the outer surface of the second bracket 170 through the third clearance opening. The protrusion 115 is used to trigger the first switch 310 when the door 410 is closed.

[0331] In this embodiment, the second bracket 170 is also provided with a third clearance opening. The interlocking system 100 also includes a protrusion 115 and a first switch 310. The protrusion 115 is correspondingly arranged with the third clearance opening, and the protrusion 115 extends out of the outer surface of the second bracket 170 through the third clearance opening. That is to say, the third clearance opening has the function of avoiding the protrusion 115. The protrusion 115 can trigger the first switch 310 to work when the door 410 is closed. The first switch 310 is connected to the control panel 430 of the cooking appliance 400.

[0332] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 29 , Figure 30 , Figure 71 and Figure 72 As shown, based on the above embodiment, the interlocking system 100 further includes a push rod 330 and a second switch 320. The push rod 330 is rotatably connected to the first bracket 160. When the door 410 is closed, the door hook 411 can drive the push rod 330 to move so that a part of the push rod 330 triggers the second switch 320.

[0333] In this embodiment, the interlocking system 100 further includes a push rod 330 and a second switch 320. Specifically, when the door 410 is closed, the door 410 moves toward the cooking cavity of the cooking appliance 400, and the door hook 411 can drive the push rod 330 to move relative to the first bracket 160. The push rod 330 moves to trigger the second switch 320. The second switch 320 is connected to the control panel 430 of the cooking appliance 400.

[0334] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 33 , Figure 71 and Figure 72 As shown, based on the above embodiment, the number of door hooks 411 is further increased to a plurality of them, including at least a first door hook and a second door hook, and the mating part 110 is mated with the first door hook; the interlocking system 100 also includes a locking part 340, which is disposed on the first bracket 160 and is used to limit the engagement with the second door hook when the door 410 is closed.

[0335] In this embodiment, there are multiple door hooks 411. The types of multiple door hooks 411 are divided. The multiple door hooks 411 include at least a first door hook and a second door hook. The first door hook cooperates with the mating part 110, and the second door hook cooperates with the locking part 340.

[0336] Specifically, the locking member 340 is used to engage with the second door hook when the door 410 is closed. The locking member 340 has the function of fixing and limiting the second door hook to ensure that the door 410 is effectively closed.

[0337] Since there are multiple door hooks 411, closing the door 410 increases the contact area and contact angle between the door 410 and the appliance body 420 of the cooking appliance 400, thus ensuring the stability and reliability of opening and closing the door 410.

[0338] In practical applications, the first door hook is fixed relative to the door body 410, that is, the first door hook is a fixed door hook 411, and the second door hook is also a fixed door hook 411. The specific settings can be configured according to actual needs.

[0339] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 33 , Figure 71 and Figure 72 As shown, based on the above embodiment, the locking member 340 further includes a locking part 341, which is movably connected to the first bracket 160. The locking part 341 is provided with an inclined surface and a limiting surface, which are correspondingly provided. The inclined surface is used to allow the second door hook to transition to the limiting surface.

[0340] In this embodiment, the locking member 340 includes a locking part 341, and the structure of the locking part 341 is defined. The locking part 341 is provided with an inclined surface and a limiting surface. The inclined surface and the limiting surface are respectively provided. The inclined surface has a guiding function, so that when the door 410 is closed, the second door hook can slide down to the limiting surface under the guiding function of the inclined surface, so as to achieve the purpose of limiting the locking member 340 and the second door hook.

[0341] Furthermore, the locking part 341 is movably connected to the first bracket 160, that is, the locking part 341 can move relative to the first bracket 160. In this way, when the door 410 is opened or closed, the second door hook can be engaged or disengaged from the locking part 341.

[0342] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 33 , Figure 71 and Figure 72 As shown, based on the above embodiment, the locking part 341 is further provided with a mounting groove; the locking member 340 also includes an elastic part 342, which is located in the mounting groove and connects the locking part 341 and the first bracket 160.

[0343] In this embodiment, the locking member 340 further includes an elastic part 342, and the locking part 341 is also provided with a mounting groove, which has the function of accommodating the elastic part 342. Since the elastic part 342 is connected to the locking part 341 and the first bracket 160, the elastic part 342 can buffer the force when the locking part 341 moves, so that the locking part 341 and the first bracket 160 are more smoothly connected.

[0344] Furthermore, by providing the elastic part 342, the locking part 341 can be moved and then reset to ensure effective limiting cooperation between the second door hook and the locking part 341.

[0345] The elastic part 342 includes springs and tension springs, etc. The specific configuration can be adjusted according to actual needs.

[0346] Example 10:

[0347] According to a second aspect of the present invention, a cooking utensil 400 is provided, including an interlocking system 100 as provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the interlocking system 100, which will not be described in detail here.

[0348] like Figure 75 , Figure 76 , Figure 77 , Figure 78 , Figure 79 , Figure 80 , Figure 81 , Figure 82 , Figure 83 , Figure 84 and Figure 85 As shown, the cooking appliance 400 further includes an appliance body 420 and a door 410. The appliance body 420 is provided with a cooking cavity. The interlocking system 100 is provided in the appliance body 420 and located at the opening end of the cooking cavity. The door 410 is connected to the appliance body 420 in an openable and closable manner. The door 410 includes a door hook 411.

[0349] The cooking appliance 400 provided in this embodiment of the invention includes an appliance body 420, an interlocking system 100, and a door 410. Specifically, the appliance body 420 is provided with a cooking cavity, the door 410 is disposed on the appliance body 420 and the door 410 can open or close the cooking cavity, and the interlocking system 100 is disposed on the appliance body 420 and is located at the opening end of the cooking cavity. It can be understood that after the user opens the door 410, the food inside the cooking cavity can be taken out or put in through the opening end of the cooking cavity.

[0350] The door body 410 includes a door hook 411, which is fixed relative to the door body 410. That is, the door hook 411 is a fixed door hook, and the opening and closing operation of the door body 410 is achieved through the cooperation of the fixed door hook 411 with the mating part 110. It is worth noting that the door body 410 is provided with an upper door hook 411 and a lower door hook 411. Both the upper and lower door hooks 411 can be fixed, or the lower door hook 411 can be fixed while the upper door hook 411 is movable; the specific configuration can be determined according to actual needs.

[0351] Microwave ovens in this technology allow users to open or close the cooking cavity by pulling or pressing the door to access food inside. However, because they lack child locks and the opening force is less than 25N, children can easily accidentally press the door button or pull the handle, opening the door with a light press or pull, resulting in burns from heated food or utensils inside the cooking cavity.

[0352] The limiting member 120 can move between a first position and a second position, and the transmission mechanism 130 can push the limiting member 120 from the first position to the second position. Specifically, when the limiting member 120 is in the first position, the limiting member 120 can restrict the movement of the mating member 110. Since the limiting member 120 restricts the movement of the mating member 110, and the mating groove 111 of the mating member 110 engages with the door hook 411, the door hook 411 cannot move to the open position, even if the door hook 411 is locked in the closed position. That is to say, when the limiting member 120 is in the first position, even if the handle of the door body 410 is pulled, the door body 410 cannot be opened.

[0353] When the door 410 needs to be opened, the transmission mechanism 130 pushes the limiting member 120 from the first position to the second position. When the limiting member 120 is in the second position, the limiting member 120 can release the movement restriction on the mating member 110. That is, the mating member 110 is unlocked. At this time, when the handle of the door 410 is pulled, the door hook 411 can drive the mating member 110 to move until the door hook 411 slides out of the mating groove 111. Then the door hook 411 moves to the open position, realizing the opening operation of the door 410.

[0354] By setting the limiting member 120 to move between a first position and a second position, when you want to open the door 410, you need to first make the transmission mechanism 130 push the limiting member 120 to the second position, thereby releasing the movement restriction on the mating member 110, so that the door can be opened. This increases the steps to open the door 410, thereby increasing the difficulty of opening the door 410. This reduces the risk of children being burned by the heated food or utensils in the cooking cavity due to accidentally touching the door opening button or handle and opening the oven door with a light press or pull. It effectively avoids misoperation and thus effectively improves the safety of using the cooking appliance 400 with this interlocking system 100.

[0355] like Figure 85 As shown, based on the above embodiment, the cooking appliance 400 further includes a control panel 430, which is disposed on the appliance body 420. The control panel 430 is provided with a second clearance opening, and the trigger part 1321 of the interlocking system 100 is exposed on the control panel 430 through the second clearance opening.

[0356] In this embodiment, the cooking appliance 400 also includes a control panel 430. Specifically, the control panel 430 is disposed on the appliance body 420, and the control panel 430 is provided with a second clearance opening. The trigger part 1321 is exposed on the control panel 430 through the second clearance opening, making it convenient for the user to use the trigger part 1321 to drive the first transmission part 1322 to move the limiting member 120, thereby releasing the movement restriction on the mating member 110. This reduces the difficulty of user operation and improves the user experience.

[0357] Furthermore, by setting a second clearance opening on the control panel 430, the trigger unit 1321 can be operated. That is, only one clearance opening needs to be made on the control panel 430, which requires minimal modification to the cooking appliance 400 and helps to reduce the production cost of the cooking appliance 400.
