Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliance equipment, and particularly relates to a door lock device and a cooking appliance. Background Art

[0002] In the related art, a microwave oven with a slow-closing function does not have a child lock function, while a microwave oven with a child lock function does not have a slow-closing function. There is a need to develop a product with both slow-closing and child lock functions. Summary of the Utility Model

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

[0004] To this end, the first object of the utility model is to provide a door lock device.

[0005] The second object of the utility model is to provide a cooking appliance.

[0006] To achieve the above at least one object, according to the first aspect of the utility model, a door lock device is provided. The door lock device is used in a cooking appliance. The cooking appliance includes a box body and a door body, and the door body can open or close the box body. The door lock device includes: a bracket assembly that can be installed on the box body; a first switch member installed on the bracket assembly, and the first switch member is used to control the conduction or disconnection of the microwave generation circuit of the cooking appliance; a trigger portion that can move with the door body between a slow-closing position and a closed position. When the trigger portion is in the closed position, the door body closes the box body, and the trigger portion triggers the first switch member, and the microwave generation circuit is conducted. When the trigger portion is in the slow-closing position, the door body opens the box body, and the trigger portion shuts down the first switch member, and the microwave generation circuit is disconnected; a pulling component movably installed on the bracket assembly. When the trigger portion is in the slow-closing position and pushes the pulling component, the pulling component can drive the trigger portion to move towards the closed position; the trigger portion includes: a rod assembly that can be installed on the door body; a first trigger member connected to the rod assembly. When the trigger portion is in the slow-closing position, the first trigger member can push the pulling component, and the pulling component drives the first trigger member to move, so that the trigger portion moves towards the closed position; a second trigger member connected to the rod assembly, and the second trigger member can move along the height direction of the rod assembly. The bracket assembly has a guiding member. During the process that the pulling component drives the first trigger member to move, the second trigger member moves along the guiding member, and the height of the second trigger member increases with the guiding member. Before the trigger portion moves to the closed position, the second trigger member is separated from the guiding member, the height of the second trigger member decreases and triggers the first switch member, and the guiding member stops the second trigger member to lock the trigger portion.

[0007] The door lock device proposed in this application can be used in a cooking appliance. The cooking appliance to which the door lock device is applied includes a box body and a door body. The box body includes a cooking cavity for accommodating food materials, and the cooking appliance can cook the food materials in the cooking cavity. The door body is rotatably connected to the box body and can open or close the box body to open or close the cooking cavity. The door lock device is used to enable the door body to automatically close the box body when the included angle between the door body and the box body is small, and to lock the door body to the box body and trigger the microwave generating circuit of the cooking appliance when the door body closes the box body, so that the cooking appliance can generate microwaves under the control of the user and heat the food materials in the cooking cavity by the microwaves. The structure of the door lock device will be described below.

[0008] The door lock device proposed in this application includes a bracket assembly, a first switch member, a trigger portion, and a pulling assembly. Among them, the bracket assembly is installed on the box body, the first switch member and the pulling assembly are installed on the bracket assembly, and the trigger portion is installed on the door body. When the included angle between the door body and the box body is small, when the user applies a certain pushing force to the door body, the pulling assembly can pull the trigger portion to move, so as to drive the door body to close the box body, so as to achieve the technical effect of slow closing and small-angle automatic absorption closing of the door. The first switch member is used to control the conduction or disconnection of the microwave generating circuit of the cooking appliance. When the first switch member is triggered, the microwave generating circuit is conducted, and when the first switch member is disconnected, the microwave generating circuit is disconnected. During the process of the pulling assembly driving the trigger portion to move, the trigger portion triggers the first switch member, so that the microwave generating circuit of the cooking appliance is conducted, so that the cooking appliance can generate microwaves under the control of the user and heat the food materials in the cooking cavity by the microwaves.

[0009] Specifically, the triggering part can move with the door body between the slow - closing position and the closed position. When the triggering part is at the slow - closing position, the door body is in a state of opening the cabinet, and the included angle between the door body and the cabinet is small. In a possible technical solution, when the triggering part is at the slow - closing position, the included angle between the door body and the cabinet is less than 15°. At this time, the triggering part is far from the first switch part, the first switch part is not triggered, the microwave generating circuit is disconnected, and the cooking appliance cannot generate microwaves, so as to avoid generating microwaves in the state where the door body opens the cabinet, resulting in microwave leakage. Further, the pulling component is movably installed on the bracket component. When the triggering part is at the slow - closing position, the triggering part contacts the pulling component, and the user can apply a small thrust to the door body so that the triggering part can push the pulling component, and then the pulling component can drive the triggering part to move towards the closed position. During the process that the pulling component drives the triggering part to move towards the closed position, the triggering part triggers the first micro - switch, the microwave generating circuit is turned on, and the cooking appliance can generate microwaves under the control of the user until the triggering part moves to the closed position and the door body closes the cabinet. In this way, the technical effect of slow - closing the door and automatically absorbing the closing at a small angle can be achieved through the pulling component. In a possible technical solution, when the triggering part is at the slow - closing position, the user applying a force less than 4N to the door body can enable the triggering part to push the pulling component so that the pulling component drives the triggering part to move to the closed position.

[0010] Further, the structure of the triggering part is defined. The triggering part includes a rod component, a first triggering piece, and a second triggering piece. The rod component can be installed on the door body. The cabinet has a front cabinet board, the door body and the bracket component are respectively located on both sides of the front cabinet board, and the front cabinet board is provided with two avoidance openings. During the process that the triggering piece moves from the slow - closing position to the closed position, the first triggering piece and the second triggering piece respectively pass through their corresponding avoidance openings. The first triggering piece is connected to the rod component. When the triggering part is at the slow - closing position, the first triggering piece can push the pulling component under the push of the user, and the pulling component rotates relative to the bracket component under the push of the first triggering piece. As the pulling component rotates, the first triggering piece is gradually clamped by the pulling component, and the pulling component then drives the first triggering piece to move so that the triggering part can move towards the closed position. In this way, the technical effect of slow - closing the door and automatically absorbing the closing at a small angle can be achieved through the pulling component.

[0011] Further, the second trigger is connected to the rod assembly, and the second trigger can move up and down along the height direction of the rod assembly under the action of an external force. The bracket assembly has a guide member for guiding the second trigger. During the process of the pulling assembly driving the first trigger to move, the first trigger drives the rod assembly to move, the rod assembly drives the second trigger to move, and the second trigger moves along the guide member after contacting the guide member. Specifically, the heights of the two ends of the guide member are different. During the process of the second trigger moving along the guide member, the height of the second trigger increases as the guide member rises. Before the trigger part moves to the closed position, the second trigger separates from the guide member, and the height of the second trigger without the support of the guide member decreases and contacts the first switch member. At this time, the second trigger triggers the first switch member, and the microwave generation circuit of the cooking appliance is turned on. Moreover, since the height of the second trigger decreases, the end face of the guide member on the side close to the first switch member can block the second trigger. When the user pulls the door body outwards, the guide member limits the movement of the second trigger, and the second trigger cannot move further, thereby preventing the trigger part from moving from the closed position to the slow-close position to lock the trigger part, and further locking the door body to the cabinet body to realize the child lock function of the door lock device.

[0012] By providing a pulling assembly in the door lock device, the first trigger of the trigger part can be driven to move by the pulling assembly, and then the whole trigger part can be driven to move towards the closed position. Since the trigger part is installed on the door body, when the trigger part moves towards the closed position, the door body can be automatically closed to the cabinet body, achieving the technical effect of slow-closing the door and automatically absorbing the closing at a small angle. By setting the guide member to have a structure with one end high and one end low, the second trigger can be limited by the guide member to prevent the trigger part from moving from the closed position to the slow-close position to lock the trigger part, and further lock the door body to the cabinet body to realize the child lock function of the door lock device.

[0013] According to the above door lock device of the present invention, the following distinguishing technical features may also be provided:

[0014] In some technical solutions, optionally, the rod assembly includes: a first rod, the first trigger is connected to the first rod; a second rod, the second trigger is connected to the second rod, the second rod is movably installed on the first rod, and the second rod can move relative to the first rod along the height direction of the first rod; a first elastic member, connected to the end of the second rod away from the first rod. During the process of the height of the second trigger increasing, the second trigger drives the second rod to move in a direction away from the first rod, and the first elastic member is compressed. When the second trigger separates from the guide member, the first elastic member pushes the second rod to move in a direction towards the first rod to reduce the height of the second trigger.

[0015] In this technical solution, the structure of the rod assembly is defined. The rod assembly includes a first rod and a second rod. The first trigger is connected to the first rod, the second trigger is connected to the second rod, and the second rod is movably connected to the first rod, so that the second trigger can move up and down along the height direction of the rod assembly. Specifically, the top of the first rod has a mounting groove, a part of the bottom of the second rod is inserted into the mounting groove, and the second rod can move along the height direction of the first rod under the action of an external force.

[0016] Furthermore, the rod assembly also includes a first elastic member, which is connected to an end of the second rod away from the first rod. When the second trigger member drives the second rod to move in a direction away from the first rod, the first elastic member is compressed so that the first elastic member generates a thrust on the second rod in a direction toward the first rod. When the second trigger member is not separated from the guide member, the guide member supports the second trigger member, and the second rod will not move toward the first rod under the thrust of the first elastic member. After the second trigger member is separated from the guide member, the second trigger member loses the support force of the guide member. At this time, the first elastic member can push the second rod to move in a direction toward the first rod, and the second rod simultaneously drives the second trigger member to move so that the height of the second trigger member is reduced. Wherein, the first elastic member can be a spring.

[0017] Specifically, after the first trigger member pushes the pull assembly, the pull assembly drives the first trigger member to move so that the trigger part moves from the slow closing position to the closed position, and in this process, the second trigger member moves along the guide member. In the process of the second trigger member moving along the guide member, the second trigger member rises with the height of the guide member, and the second trigger member drives the height of the second rod member to rise synchronously, and the second rod member moves in the direction away from the first rod member. In this process, the first elastic member is compressed, and the first elastic member generates a thrust in the direction toward the first rod member on the second rod member. After the second trigger member moves to the end of the guide member and separates from the guide member, the first elastic member pushes the second rod member to move in the direction toward the first rod member, and the second rod member drives the second trigger member to move, and the height of the second trigger member decreases and contacts the first switch member, and the first switch member is triggered. After the first switch member is triggered by the second trigger member, the first elastic member still has a thrust in the direction toward the first rod member on the second rod member, so that the second trigger member can be closely contacted with the first switch member, avoiding the separation between the second trigger member and the first switch member, so that the first switch member can be stably in a re-triggered state, and avoiding the microwave generating circuit from being interrupted. Furthermore, since the second trigger member can maintain a stable position under the thrust of the first elastic member, the reliability of the guide member limiting the second trigger member can be improved, thereby improving the reliability of the child lock function of the door lock device and allowing the door body to be more securely locked to the box body.

[0018] In some technical solutions, optionally, the guiding member has a first guiding surface, a second guiding surface, and a third guiding surface that are sequentially arranged. During the process of the triggering portion moving from the slow-closing position to the closing position, the second triggering member sequentially passes through the first guiding surface, the second guiding surface, and the third guiding surface; wherein, the second triggering member avoids the first guiding surface, the second triggering member can move along the second guiding surface and the third guiding surface, the second guiding surface is a curved surface protruding towards the second triggering member, and the third guiding surface is a plane tangent to the second guiding surface.

[0019] In this technical solution, the structure of the guiding member is defined. The guiding member includes a first guiding surface, a second guiding surface, and a third guiding surface, which are sequentially arranged. During the process of the triggering portion moving from the slow-closing position to the closing position, the second triggering member sequentially passes through the first guiding surface, the second guiding surface, and the third guiding surface. Among them, the first guiding surface can be a plane, an inclined plane, or a curved surface. During the process of the second triggering member passing through the first guiding surface, the second triggering member avoids the first guiding surface, that is, there is a spacing between the second triggering member and the first guiding surface. Specifically, the dimension range of this spacing is 1 mm to 5 mm. In this way, the resistance received by the second triggering member during movement can be reduced, and the pulling force generated by the driving assembly on the first triggering member during the initial rotation stage is relatively small. By making the second triggering member avoid the first guiding surface, the friction between the second triggering member and the first guiding surface can be avoided, so that the triggering portion can smoothly move towards the closing position and prevent the triggering portion from getting stuck during the movement.

[0020] Furthermore, the second guiding surface is a curved surface protruding towards the second triggering member, and the height of the end where the second guiding surface is connected to the third guiding surface is higher than the height of the end where the second guiding surface is connected to the first guiding surface. Compared with the structure in which the second guiding surface is set as an inclined plane, in this application, by setting the second guiding surface as a curved surface protruding towards the second triggering member, the climbing stroke and duration of the second triggering member along the second guiding surface can be increased, the climbing force of the second triggering member can be increased, and the success rate of the door body automatically closing the box body can be improved. Specifically, by setting the second guiding surface as a curved surface protruding towards the second triggering member, the climbing force of the second triggering member can be increased by more than 20%, and the success rate of the door body automatically closing the box body can be increased by 35%. On the other hand, by setting the second guiding surface as a curved surface protruding towards the second triggering member, it can be ensured that the second triggering member smoothly crosses the second guiding surface and avoids the second triggering member getting stuck during the movement.

[0021] Furthermore, the third guiding surface is a plane tangent to the second guiding surface, and the length range of the third guiding surface is 3 mm to 6 mm, which can enable the second triggering member to move smoothly after separating from the second guiding surface.

[0022] In some technical solutions, optionally, the actuating assembly includes: a driving member rotatably connected to the bracket assembly. When the triggering portion is in the slow-closing position, the first trigger member abuts against the driving member, and the first trigger member can push the driving member to rotate relative to the bracket assembly. The driving member has a bayonet; a plurality of second elastic members, one end of any second elastic member is connected to the bracket assembly, and the other end is connected to the driving member. When the driving member is in the equilibrium position, the driving member can overcome the pulling force of the second elastic member and remain stationary. After the first trigger member pushes the driving member to deviate from the equilibrium position, the second elastic member can pull the driving member to rotate relative to the bracket assembly, at least a part of the first trigger member moves into the bayonet, and the driving member can drive the first trigger member to move so that the triggering portion moves towards the closed position.

[0023] In this technical solution, the structure of the actuating assembly is defined. The actuating assembly includes a driving member and a plurality of second elastic members. The driving member is rotatably installed on the bracket assembly. The first trigger member can be clamped to the driving member. One end of the second elastic member is connected to the bracket assembly, and the other end is connected to the driving member. The second elastic member can pull the driving member to rotate relative to the bracket assembly, and then drive the first trigger member to move through the driving member, so that the trigger member can move towards the closed position, achieving the technical effect of slow closing of the door and automatically absorbing the closing at a small angle.

[0024] Specifically, when the triggering portion is in the slow-closing position, the first trigger member abuts against the driving member. At this time, the driving member is in the equilibrium position, and the driving member can overcome the pulling force of the second elastic member to remain stationary. When the user applies a pushing force on the door body towards the direction of the box body, the first trigger member can push the driving member to rotate relative to the bracket assembly, and the driving member deviates from the equilibrium position. Specifically, when the driving member is in the equilibrium position, the extending directions of the plurality of second elastic members are different, and the sizes of the plurality of second elastic members are different, so that the plurality of second elastic members generate pulling forces with different sizes and directions on the driving member. The pulling forces generated by the plurality of second elastic members on the driving member and the gravity of the driving member itself overcome each other, so that the driving member can remain stationary in the equilibrium position. The second elastic member can be a spring.

[0025] Further, after the driving member deviates from the equilibrium position under the pushing force of the first trigger member, the second elastic member can pull the driving member to rotate relative to the bracket assembly. The driving member has a bayonet. As the driving member rotates, at least a part of the first trigger member moves into the bayonet, and the first trigger member can be clamped in the bayonet, so that the driving member can drive the first trigger member to move, and then the triggering portion can move towards the closed position. In this way, the technical effect of slow closing of the door and automatically absorbing the closing at a small angle can be achieved.

[0026] In some technical solutions, optionally, the actuating assembly further includes: a swing block, which is mounted on the driving member; a damper, which is mounted on the bracket assembly, the swing block is connected to the damper, and when the driving member rotates relative to the bracket assembly, the damper generates a resistance force on the swing block to slow down the rotation speed of the driving member.

[0027] In this technical solution, the structure of the actuating assembly is further defined. The actuating assembly further includes a swing block and a damper. Among them, the swing block is mounted on the driving member, the damper is mounted on the bracket and connected to the swing block. The damper can apply a resistance force to the swing block when the driving member drives the swing block to rotate, so that the triggering part can move smoothly, achieving the technical effect of slow closing of the door.

[0028] Specifically, after the user pushes the door body to make the first trigger push the driving member to deviate from the equilibrium position, the driving member rotates relative to the bracket assembly and drives the first trigger to move. During the process of the driving member rotating relative to the bracket assembly, the driving member drives the swing block to rotate, the damper generates a resistance force on the swing block, and the swing block transmits the resistance force to the driving member. In this way, the rotation speed of the driving member can be slowed down, and then the moving speed of the first trigger can be slowed down. Since the triggering part is mounted on the door body, when the moving speed of the first trigger is slowed down, the closing speed of the door body is slowed down, so that the technical effect of slow closing of the door can be achieved, avoiding damage to the door body and the box body caused by the door body closing too fast, and also avoiding too loud closing sound, improving the user experience.

[0029] In some technical solutions, optionally, the driving member has a swing block groove, and the swing block is movably mounted in the swing block groove, and there is a gap between the swing block and the groove wall of the swing block groove.

[0030] In this technical solution, the installation method of the swing block is defined. The driving member has a swing block groove, and the swing block is mounted in the swing block groove. There is a gap between the swing block and the groove wall of the swing block groove, and the swing block can rotate or move relative to the driving member in the swing block groove. It can be understood that during the process of the driving member driving the swing block to rotate, due to the pulling force of multiple second elastic members of the driving member, since the swing block is connected to the damper, the damper will generate a resistance force on the swing block, and the swing block transmits the resistance force to the driving member, and the pulling force of the second elastic member overcomes the resistance force transmitted by the swing block to the driving member. If there is no gap between the swing block and the swing block groove, then the swing block will rotate synchronously with the driving member, which is likely to cause the swing block to get stuck when the driving member rotates to a certain position, and then the driving member cannot rotate normally. In order to prevent the swing block from getting stuck in the swing block groove, this application leaves a gap between the swing block and the groove wall of the swing block groove so that the swing block can rotate or move smoothly in the swing block groove.

[0031] In some technical solutions, optionally, the bracket assembly has a damper receiving cavity, the damper is movably mounted in the damper receiving cavity, there is a gap between the damper and the cavity wall of the damper receiving cavity, and the damper can swing in the damper receiving cavity.

[0032] In this technical solution, the installation method of the damper is defined. The bracket assembly has a damper receiving cavity, and the damper is movably installed in the damper receiving cavity. Specifically, when the driving member rotates relative to the bracket assembly, the driving member drives the swing block to rotate, and the swing block drives the damper to swing in the damper receiving cavity. There is a gap between the damper and the cavity wall of the damper receiving cavity. In this way, it can be avoided that the cavity wall of the damper receiving cavity blocks the damper when the damper swings, thereby avoiding jamming of the driving member during rotation, ensuring that the triggering portion can smoothly move between the slow closing position and the closing position, and further ensuring that the door body can normally open and close the cabinet body.

[0033] In some technical solutions, optionally, the door lock device further includes: a second switch member installed on the bracket assembly, and the second switch member is used to open or close the monitoring circuit of the cooking appliance; a third triggering member connected to the driving member, and during the process that the pulling assembly drives the triggering portion to move towards the closing position, the third triggering member first triggers the second switch member, and then the second triggering member triggers the first switch member.

[0034] In this technical solution, the structure of the door lock device is further defined. The door lock device further includes a second switch member and a third triggering member. The cooking appliance has a monitoring circuit for monitoring whether the triggering portion moves from the slow closing position to the closing position. The second switch member is used to open or close the monitoring circuit of the cooking appliance, and the third triggering member is used to trigger the second switch member.

[0035] Specifically, the second switch member is installed on the bracket assembly, the third triggering member is connected to the driving member, and the driving member can drive the third triggering member to move to trigger or turn off the second switch member. During the process that the pulling assembly drives the triggering portion to move towards the closing position, the driving member rotates relative to the bracket assembly under the pulling force of the second elastic member. During the rotation of the driving member, the driving member drives the third triggering member to move towards the second switch member, and at the same time the driving member drives the first triggering member to move, and the first triggering member drives the second triggering member to move towards the first switch member through the rod assembly. During the process that the pulling assembly drives the triggering portion to move towards the closing position, the third triggering member first triggers the second switch member, and then the second triggering member triggers the first switch member. That is, the second switch member is triggered first, and the monitoring circuit is turned on, indicating that at this time the triggering portion moves from the slow closing position to the closing position, and the door body is about to close the cabinet body. Then the second triggering member triggers the first switch member, and the microwave generating circuit is turned on, and the cooking appliance can generate microwaves under the control of the user. In this way, the cooking appliance can have the ability to generate microwaves after confirming that the door body is about to close the cabinet body, avoiding the generation of microwaves when the door body opens the cabinet body, avoiding microwave leakage, and improving the safety of the cooking appliance.

[0036] In some technical schemes, optionally, the bracket assembly includes: a frame body; an end cover, the frame body and the end cover together form an installation cavity, the driving member and the pendulum block are located in the installation cavity, the second switch member is installed on the side of the end cover away from the frame body, the end cover has a trigger opening, and the third trigger member extends out of the trigger opening and can move in the trigger opening.

[0037] In this technical solution, the structure of the bracket assembly is defined. The bracket assembly includes a frame body and an end cover, and the end cover is detachably connected to the frame body. When the end cover is connected to the frame body, the end cover and the frame body enclose an installation cavity, and the driving member and the pendulum block are located in the installation cavity. In this way, on the one hand, the driving member and the pendulum block can be protected, and on the other hand, the driving member and the pendulum block can be limited by the end cover.

[0038] Furthermore, the end cover is provided with a trigger opening so that the third trigger member can trigger the second switch member. Specifically, the second switch member is installed on the side of the end cover away from the frame, that is, the second switch member is located outside the installation cavity, which makes it easy to repair and replace the second switch member, and the third trigger member extends out of the trigger opening, and the driving member can drive the third trigger member to move in the trigger opening so that the third trigger member can trigger the second switch member.

[0039] In some technical solutions, optionally, the door lock device also includes: a third switch component installed on the bracket assembly; the pulling assembly also includes: a rocker arm rotatably connected to the bracket assembly, and when the trigger part moves to the closed position, the first trigger component pushes the rocker arm to rotate so that the rocker arm triggers the third switch component.

[0040] In this technical solution, the structure of the door lock device is further defined. The door lock device also includes a third switch component, which is installed on the bracket assembly. When the trigger component moves to the closed position, the third switch component is triggered, so that it can be confirmed that the trigger component is in the closed position at this time and the door body has closed the box body. The pull assembly also includes a swing rod for triggering the third switch component. The swing rod is rotatably connected to the bracket assembly. When the trigger part moves to the closed position, the first trigger component pushes the swing rod to rotate, so that the swing rod turns to the third switch component and triggers the third switch component.

[0041] By arranging a third switch component in the door lock device and a rocker rod in the actuating assembly, the trigger part can push the rocker rod to rotate through the first trigger component when moving to the closed position, so that the rocker rod triggers the third switch component, thereby confirming that the trigger part is now in the closed position and the door body has closed the box body.

[0042] In some technical solutions, optionally, in the process of the triggering portion moving from the slow-closing position to the closing position, the second switch element, the first switch element and the third switch element are triggered in sequence.

[0043] In this technical solution, the triggering sequence of the first switch member, the second switch member, and the third switch member is defined. Specifically, during the process in which the triggering part moves from the slow-closing position to the closed position, the second switch member, the first switch member, and the third switch member are triggered in sequence. Understandably, the second switch member is triggered when the triggering part moves from the slow-closing position to the closed position. When the second switch member is triggered, the monitoring circuit of the cooking appliance is turned on. The fact that the monitoring circuit is turned on indicates that at this time the triggering part moves from the slow-closing position to the closing position, and the door body is about to close the cabinet body. When the first switch member is triggered, the microwave generating circuit of the cooking appliance is turned on, and the cooking appliance can generate microwaves. The third switch member is triggered when the triggering part is in the closed position. When the third switch member is triggered, it can be confirmed that the triggering part is in the closed position and the door body has closed the cabinet body.

[0044] By enabling the second switch member, the first switch member, and the third switch member to be triggered in sequence during the process in which the triggering part moves from the slow-closing position to the closed position, the cooking appliance can be made to have the ability to generate microwaves only after confirming that the door body is about to close the cabinet body, avoiding the generation of microwaves when the door body of the cooking appliance is open, preventing microwave leakage, and enhancing the safety of the cooking appliance. And it can confirm that the triggering part has moved to the closed position and the door body has closed the cabinet body after the cooking appliance has the ability to generate microwaves, facilitating the user's operation of the cooking appliance.

[0045] In some technical solutions, optionally, the triggering part further includes: an unlocking member connected to the side of the rod assembly facing the outside, and the unlocking member can drive the second triggering member to rise so that the second triggering member is separated from the first switch member and avoids the guiding member.

[0046] In this technical solution, the structure of the triggering part is further defined. The triggering part further includes an unlocking member, and the unlocking member is connected to the side of the rod assembly facing the outside. Specifically, the unlocking member is exposed outside the door body to facilitate the user to apply a force to the unlocking member. When it is necessary to unlock the door body from the cabinet body, the user can apply an upward force to the unlocking member to make the unlocking member rise. Since both the unlocking member and the second triggering member are connected to the second rod, the unlocking member can drive the second triggering member to rise through the second rod. In this way, the second triggering member can be separated from the first switch member and avoid the guiding member. After the second triggering member is separated from the first switch member, the first switch member returns to the untriggered state, and the microwave generating circuit is disconnected, and the cooking appliance cannot generate microwaves. The unlocking member drives the second triggering member to rise to a position where it can avoid the guiding member through the second rod. At this time, the guiding member can no longer stop and limit the second triggering member, and the door lock device is in the unlocked state. The door body is unlocked from the cabinet body, and then the user can pull the door body outwards to open the cabinet body.

[0047] By arranging an unlocking member in the triggering part, a user can complete the actions of unlocking and opening the door body with one - hand operation. First, the user raises the unlocking member so that the second triggering member can avoid the guiding member to unlock the door body from the box body, and then pulls the door body to open the box body. Both the unlocking and door - opening actions can be completed with one hand, improving the user's convenience of use.

[0048] In some technical solutions, optionally, during the process of the triggering part moving from the closed position to the slow - closing position, the first switch member, the third switch member, and the second switch member are shut down in sequence.

[0049] In this technical solution, the shutdown sequence of the first switch member, the second switch member, and the third switch member is defined. Specifically, during the process of the triggering part moving from the closed position to the slow - closing position, the first switch member, the third switch member, and the second switch member are shut down in sequence. Understandably, during the process of the user opening the door body, the user needs to first raise the unlocking member in the triggering part to unlock the door body from the box body. When the user raises the unlocking member, the unlocking member drives the second triggering member to separate from the first switch member, and the first switch member is shut down, and the cooking appliance cannot generate microwaves. When the second triggering member rises to a position where it can avoid the guiding member, the guiding member can no longer stop and limit the second triggering member, and at this time, the door body is unlocked from the box body.

[0050] Further, after the door body is unlocked from the box body, the user continues to pull the door body to open the box body, and the door body drives the triggering part to move from the closed position to the slow - closing position. During this process, the first triggering member moves away from the third switch member and the second switch member. The swing rod first separates from the third switch member, and the third switch member is shut down. Since the first triggering member is clamped at the bayonet of the driving member, during the process of the first triggering member moving away from the second switch member, the first triggering member drives the driving member to rotate. After the third switch member is shut down, the driving member drives the third triggering member to separate from the second switch member, and the second switch member is shut down.

[0051] By shutting down the first switch member, the third switch member, and the second switch member in sequence during the process of the triggering part moving from the closed position to the slow - closing position, it can be ensured that the cooking appliance loses the ability to generate microwaves before the user opens the door body, avoiding microwave leakage and improving the safety of the cooking appliance.

[0052] The second aspect of the present utility model also provides a cooking appliance, including: the door lock device proposed in the first aspect of the present utility model; a box body having a cooking cavity, and the bracket assembly of the door lock device is installed on the box body; a door body rotatably connected to the box body, the door body is used to open or close the cooking cavity, and the triggering part of the door lock device is installed on the door body.

[0053] The cooking appliance proposed in this application includes a cabinet, a door body, and a door lock device. Among them, the cabinet has a cooking cavity, the door body is rotatably connected to the cabinet, and the door body can open or close the cabinet to open or close the cooking cavity. The door lock device includes a bracket assembly and a trigger part. Among them, the trigger part is installed on the door body, and the bracket assembly is installed on the cabinet. The door lock device further includes a first switch member and a pulling assembly, and the first switch member and the pulling assembly are installed on the bracket assembly. When the user closes the door body, the door body is first pushed by the user to a position with a smaller included angle with the cabinet. At this time, the trigger part is driven by the door body to the slow-close position. As the user continues to apply a pushing force to the door body, the trigger part pushes the pulling assembly under the action of the pushing force, and the pulling assembly can drive the trigger part to move from the slow-close position to the closed position. During the process of the trigger part moving to the closed position, the trigger part drives the door body to rotate towards the cabinet until the trigger part moves to the closed position and the door body closes the cabinet.

[0054] Further, during the process of the trigger part moving from the slow-close position to the closed position, the trigger part triggers the first switch member, and the microwave generation circuit of the cooking appliance is turned on, and the cooking appliance has the ability to generate microwaves.

[0055] The cooking appliance provided in the second aspect of the present utility model includes the door lock device proposed in the first aspect of the present utility model, and thus has all the beneficial effects of the door lock device.

[0056] The cooking appliance can be a microwave oven, a microwave grill, or a microwave steam oven combination.

Detailed implementation manners

[0076] In order to be able to more clearly understand the above-mentioned objects, 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 implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0077] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0078] Next, refer to Figures 1 to 15 Describe the door lock device 100 and the cooking appliance 200 provided according to some embodiments of the present invention.

[0079] In an embodiment according to the present application, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown in the figure, the present utility model provides a door lock device 100, which is used in a cooking appliance 200. The cooking appliance 200 includes a box body 210 and a door body 220. The door body 220 can open or close the box body 210. The door lock device 100 includes: a bracket assembly 110, which can be installed on the box body 210; a first switch member 120, installed on the bracket assembly 110, and the first switch member 120 is used to control the conduction or disconnection of the microwave generation circuit of the cooking appliance 200; a trigger portion 130, which can move with the door body 220 between a slow closing position and a closed position. When the trigger portion 130 is in the closed position, the door body 220 closes the box body 210, and the trigger portion 130 triggers the first switch member 120, and the microwave generation circuit is conducted. When the trigger portion 130 is in the slow closing position, the door body 220 opens the box body 210, the trigger portion 130 shuts down the first switch member 120, and the microwave generation circuit is disconnected; a pulling assembly 140, movably installed on the bracket assembly 110. When the trigger portion 130 is in the slow closing position and pushes the pulling assembly 140, the pulling assembly 140 can drive the trigger portion 130 to move towards the closed position; the trigger portion 130 includes: a rod assembly 131, which can be installed on the door body 220; a first trigger member 132, connected to the rod assembly 131. When the trigger portion 130 is in the slow closing position, the first trigger member 132 can push the pulling assembly 140, and the pulling assembly 140 drives the first trigger member 132 to move, so that the trigger portion 130 moves towards the closed position; a second trigger member 133, connected to the rod assembly 131, and the second trigger member 133 can move along the height direction of the rod assembly 131. The bracket assembly 110 has a guiding member 150. During the process of the pulling assembly 140 driving the first trigger member 132 to move, the second trigger member 133 moves along the guiding member 150, and the height of the second trigger member 133 increases with the increase of the guiding member 150. Before the trigger portion 130 moves to the closed position, the second trigger member 133 is separated from the guiding member 150, the height of the second trigger member 133 decreases and triggers the first switch member 120, and the guiding member 150 stops the second trigger member 133 to lock the trigger portion 130.

[0080] As Figure 1As shown, the door lock device 100 proposed in this application can be used in the cooking appliance 200. The cooking appliance 200 that the door lock device 100 is used for includes a box body 210 and a door body 220. The box body 210 includes a cooking cavity 211 for accommodating food materials, and the cooking appliance 200 can cook the food materials in the cooking cavity 211. The door body 220 is rotatably connected to the box body 210, and the door body 220 can open or close the box body 210 to open or close the cooking cavity 211. The door lock device 100 is used to enable the door body 220 to automatically close the box body 210 when the angle between the door body 220 and the box body 210 is small, and to lock the door body 220 to the box body 210 and trigger the microwave generation circuit of the cooking appliance 200 when the door body 220 closes the box body 210, so that the cooking appliance 200 can generate microwaves under the control of the user and heat the food materials in the cooking cavity 211 by microwaves. The structure of the door lock device 100 will be described below.

[0081] As Figure 3 , Figure 4 and Figure 5 shown, the door lock device 100 proposed in this application includes a bracket assembly 110, a first switch member 120, a trigger portion 130, and a pulling assembly 140. Among them, the bracket assembly 110 is installed on the box body 210, the first switch member 120 and the pulling assembly 140 are installed on the bracket assembly 110, and the trigger portion 130 is installed on the door body 220. When the angle between the door body 220 and the box body 210 is small, when the user applies a certain pushing force to the door body 220, the pulling assembly 140 can pull the trigger portion 130 to move, so as to drive the door body 220 to close the box body 210, so as to achieve the technical effect of slow closing and small-angle automatic absorption and closing of the door. The first switch member 120 is used to control the conduction or disconnection of the microwave generation circuit of the cooking appliance 200. When the first switch member 120 is triggered, the microwave generation circuit is conducted, and when the first switch member 120 is disconnected, the microwave generation circuit is disconnected. During the process of the pulling assembly 140 driving the trigger portion 130 to move, the trigger portion 130 triggers the first switch member 120, so that the microwave generation circuit of the cooking appliance 200 is conducted, so that the cooking appliance 200 can generate microwaves under the control of the user and heat the food materials in the cooking cavity 211 by microwaves.

[0082] Specifically, the trigger portion 130 can move with the door body 220 between the slow closing position and the closed position, as Figure 6As shown, when the triggering part 130 is in the slow - closing position, the door body 220 is in the state of opening the box body 210, and the included angle between the door body 220 and the box body 210 is small. In a possible embodiment, when the triggering part 130 is in the slow - closing position, the included angle between the door body 220 and the box body 210 is less than 15°. At this time, the triggering part 130 is far from the first switch part 120, the first switch part 120 is not triggered, the microwave generating circuit is disconnected, and the cooking appliance 200 cannot generate microwaves, so as to avoid generating microwaves when the door body 220 opens the box body 210, resulting in microwave leakage. Further, the pulling component 140 is movably installed on the bracket component 110. When the triggering part 130 is in the slow - closing position, the triggering part 130 contacts the pulling component 140. The user can apply a small thrust to the door body 220 so that the triggering part 130 can push the pulling component 140, and then the pulling component 140 can drive the triggering part 130 to move towards the closing position. During the process that the pulling component 140 drives the triggering part 130 to move towards the closing position, the triggering part 130 triggers the first micro - switch, the microwave generating circuit is turned on, and the cooking appliance 200 can generate microwaves under the control of the user until the triggering part 130 moves to the closing position and the door body 220 closes the box body 210. In this way, the technical effect of slow - closing the door and automatically absorbing the closing at a small angle can be achieved through the pulling component 140. In a possible embodiment, when the triggering part 130 is in the slow - closing position, the user applying a force less than 4N to the door body 220 can enable the triggering part 130 to push the pulling component 140, so that the pulling component 140 drives the triggering part 130 to move to the closing position.

[0083] Further, the structure of the triggering part 130 is defined. The triggering part 130 includes a rod component 131, a first triggering piece 132 and a second triggering piece 133, and the rod component 131 can be installed on the door body 220. As Figure 2 shown, the box body 210 has a front box plate 212. The door body 220 and the bracket component 110 are respectively located on both sides of the front box plate 212. The front box plate 212 is provided with two avoidance openings 213. During the process that the triggering piece moves from the slow - closing position to the closing position, the first triggering piece 132 and the second triggering piece 133 respectively pass through their corresponding avoidance openings 213. The first triggering piece 132 is connected to the rod component 131. As Figure 6 shown, when the triggering part 130 is in the slow - closing position, the first triggering piece 132 can push the pulling component 140 under the push of the user, and the pulling component 140 rotates relative to the bracket component 110 under the push of the first triggering piece 132. As Figure 8 and Figure 10As shown, as the driving component 140 rotates, the first trigger 132 is gradually engaged with the driving component 140, and the driving component 140 then drives the first trigger 132 to move, so that the trigger portion 130 can move towards the closed position. In this way, the technical effect of slow closing the door and automatically absorbing the closing of the door at a small angle can be achieved through the driving component 140.

[0084] Furthermore, as Figure 6 shown, the second trigger 133 is connected to the rod component 131, and the second trigger 133 can move up and down along the height direction of the rod component 131 under the action of an external force. As Figure 7 and Figure 8 shown, the bracket component 110 has a guide member 150, and the guide member 150 is used to guide the second trigger 133. During the process of the driving component 140 driving the first trigger 132 to move, the first trigger 132 drives the rod component 131 to move, the rod component 131 drives the second trigger 133 to move, and the second trigger 133 moves along the guide member 150 after contacting the guide member 150. Specifically, the heights of the two ends of the guide member 150 are different. During the process of the second trigger 133 moving along the guide member 150, the height of the second trigger 133 increases as the guide member 150 rises. Before the trigger portion 130 moves to the closed position, the second trigger 133 separates from the guide member 150, and the height of the second trigger 133 without the support of the guide member 150 decreases and contacts the first switch member 120. At this time, the second trigger 133 triggers the first switch member 120, and the microwave generating circuit of the cooking appliance 200 is turned on. Figure 9 The dotted line range at the first switch member 120 in Figure 9 and Figure 10 shows that the second trigger 133 triggers the first switch member 120. And, as

[0085] By providing a pulling component 140 in the door lock device 100, the first triggering member 132 of the triggering portion 130 can be driven to move by the pulling component 140, thereby driving the entire triggering portion 130 to move towards the closed position. Since the triggering portion 130 is installed on the door body 220, when the triggering portion 130 moves towards the closed position, the door body 220 can be automatically closed on the cabinet body 210, achieving the technical effect of slow closing and small-angle automatic absorption of closing. By setting the guiding member 150 to a structure with one end higher and the other end lower, the second triggering member 133 can be limited by the guiding member 150, preventing the triggering portion 130 from moving from the closed position to the slow closing position, locking the triggering portion 130, and further locking the door body 220 on the cabinet body 210, realizing the child lock function of the door lock device 100.

[0086] In some embodiments, optionally, as Figure 3 、 Figure 4 and Figure 5 shown, the rod assembly 131 includes: a first rod 134, the first triggering member 132 is connected to the first rod 134; a second rod 135, the second triggering member 133 is connected to the second rod 135, the second rod 135 is movably installed on the first rod 134, and the second rod 135 can move relative to the first rod 134 along the height direction of the first rod 134; a first elastic member 136, connected to the end of the second rod 135 facing away from the first rod 134. During the process of the height of the second triggering member 133 increasing, the second triggering member 133 drives the second rod 135 to move in a direction away from the first rod 134, and the first elastic member 136 is compressed. When the second triggering member 133 is separated from the guiding member 150, the first elastic member 136 pushes the second rod 135 to move in a direction towards the first rod 134, so that the height of the second triggering member 133 decreases.

[0087] In this embodiment, the structure of the rod assembly 131 is defined. As Figure 3 、 Figure 4 and Figure 5 shown, the rod assembly 131 includes a first rod 134 and a second rod 135. Among them, the first triggering member 132 is connected to the first rod 134, the second triggering member 133 is connected to the second rod 135, and the second rod 135 is movably connected to the first rod 134. In this way, the second triggering member 133 can move up and down along the height direction of the rod assembly 131. Specifically, as Figure 6 shown, the top of the first rod 134 has a mounting groove, and a part of the bottom of the second rod 135 is inserted into the mounting groove, and the second rod 135 can move along the height direction of the first rod 134 under the action of an external force.

[0088] Furthermore, as Figure 13As shown, the rod assembly 131 further includes a first elastic member 136, and the first elastic member 136 is connected to one end of the second rod 135 away from the first rod 134. When the second trigger member 133 drives the second rod 135 to move in a direction away from the first rod 134, the first elastic member 136 is compressed, so that the first elastic member 136 generates a thrust on the second rod 135 in the direction towards the first rod 134. Figure 13 The direction indicated by the arrow in Figure 13 is the thrust direction of the first elastic member 136 on the second rod 135. When the second trigger member 133 is not separated from the guide member 150, the guide member 150 supports the second trigger member 133, and the second rod 135 will not move towards the first rod 134 under the thrust of the first elastic member 136. After the second trigger member 133 is separated from the guide member 150, the second trigger member 133 loses the support force of the guide member 150. At this time, the first elastic member 136 can push the second rod 135 to move in the direction towards the first rod 134, and the second rod 135 drives the second trigger member 133 to move at the same time to reduce the height of the second trigger member 133. Among them, the first elastic member 136 can be a spring.

[0089] Specifically, after the first trigger member 132 pushes the pulling assembly 140, the pulling assembly 140 drives the first trigger member 132 to move so that the trigger portion 130 moves from the slow closing position to the closing position. During this process, the second trigger member 133 moves along the guide member 150. During the process of the second trigger member 133 moving along the guide member 150, the height of the second trigger member 133 increases with the guide member 150, and the second trigger member 133 drives the height of the second rod 135 to increase synchronously. The second rod 135 moves in a direction away from the first rod 134. During this process, the first elastic member 136 is compressed, and the first elastic member 136 generates a thrust on the second rod 135 in the direction towards the first rod 134. As Figure 13As shown, after the second trigger member 133 moves to the end of the guide member 150 and separates from the guide member 150, the first elastic member 136 pushes the second rod member 135 to move in the direction towards the first rod member 134. The second rod member 135 drives the second trigger member 133 to move. The height of the second trigger member 133 decreases and it contacts the first switch member 120, triggering the first switch member 120. After the first switch member 120 is triggered by the second trigger member 133, the first elastic member 136 still has a thrust on the second rod member 135 in the direction towards the first rod member 134. In this way, the second trigger member 133 can closely contact the first switch member 120, preventing separation between the second trigger member 133 and the first switch member 120, enabling the first switch member 120 to stably remain in the re-triggered state, and avoiding momentary interruption of the microwave generating circuit. Moreover, since the second trigger member 133 can maintain a stable position under the thrust of the first elastic member 136, the reliability of the guide member 150 in limiting the second trigger member 133 can be improved, the reliability of the child lock function of the door lock device 100 is enhanced, and the door body 220 can be more firmly locked to the cabinet body 210. Figure 13 The state where the end of the second trigger member 133 is limited is shown within the left dashed line range at the first switch member 120 in Figure 13 The state where the second trigger member 133 triggers the first switch member 120 is shown within the right dashed line range at the first switch member 120 in

[0090] In some embodiments, optionally, as Figure 15 shown, the guide member 150 has a first guide surface 151, a second guide surface 152, and a third guide surface 153 arranged in sequence. During the process of the trigger portion 130 moving from the slow-close position to the closed position, the second trigger member 133 sequentially passes through the first guide surface 151, the second guide surface 152, and the third guide surface 153. Among them, the second trigger member 133 avoids the first guide surface 151, and the second trigger member 133 can move along the second guide surface 152 and the third guide surface 153. The second guide surface 152 is a curved surface protruding towards the second trigger member 133, and the third guide surface 153 is a plane tangent to the second guide surface 152.

[0091] In this embodiment, the structure of the guide member 150 is defined. The guide member 150 includes a first guide surface 151, a second guide surface 152 and a third guide surface 153, which are arranged in sequence. In the process of the trigger part 130 moving from the slow-closing position to the closed position, the second trigger member 133 passes through the first guide surface 151, the second guide surface 152 and the third guide surface 153 in sequence. Among them, the first guide surface 151 can be a plane, an inclined surface or a curved surface. In the process of the second trigger member 133 passing through the first guide surface 151, the second trigger member 133 avoids the first guide surface 151, that is, there is a spacing between the second trigger member 133 and the first guide surface 151, and specifically, the size range of the spacing is 1mm to 5mm. In this way, the resistance encountered by the second trigger member 133 during its movement can be reduced, and the pulling force generated by the pulling component 140 on the first trigger member 132 during the initial rotation stage is relatively small. By making the second trigger member 133 avoid the first guide surface 151, the friction force between the second trigger member 133 and the first guide surface 151 can be avoided, so that the trigger part 130 can move smoothly to the closed position, preventing the trigger part 130 from getting stuck during the movement.

[0092] Further, the second guide surface 152 is a curved surface convex toward the second trigger member 133, and the height of the end of the second guide surface 152 connected to the third guide surface 153 is higher than the height of the end of the second guide surface 152 connected to the first guide surface 151. Compared with the structure in which the second guide surface 152 is set as an inclined plane, the present application sets the second guide surface 152 as a curved surface convex toward the second trigger member 133, which can increase the travel and duration of the second trigger member 133 climbing along the second guide surface 152, increase the climbing force of the second trigger member 133, and improve the success rate of the door body 220 automatically closing the box body 210. Specifically, by setting the second guide surface 152 as a curved surface convex toward the second trigger member 133, the climbing force of the second trigger member 133 can be increased by more than 20%, and the success rate of the door body 220 automatically closing the box body 210 can be increased by 35%. On the other hand, by configuring the second guide surface 152 to be a curved surface convex toward the second trigger member 133 , it is possible to ensure that the second trigger member 133 smoothly passes over the second guide surface 152 , thereby preventing the second trigger member 133 from getting stuck during movement.

[0093] Furthermore, the third guide surface 153 is a plane tangent to the second guide surface 152 , and the length of the third guide surface 153 ranges from 3 mm to 6 mm, so that the second trigger member 133 can move smoothly after being separated from the second guide surface 152 .

[0094] In some embodiments, optionally, Figure 6 , Figure 7 , Figure 8 ,Figure 10 and Figure 13 As shown in Figure 13 , the actuating assembly 140 includes: a driving member 141 rotatably connected to the support assembly 110. When the triggering portion 130 is in the slow-closing position, the first trigger member 132 abuts against the driving member 141, and the first trigger member 132 can push the driving member 141 to rotate relative to the support assembly 110. The driving member 141 has a bayonet 142; a plurality of second elastic members 143, one end of any second elastic member 143 is connected to the support assembly 110, and the other end is connected to the driving member 141. When the driving member 141 is in the equilibrium position, the driving member 141 can overcome the pulling force of the second elastic member 143 and remain stationary. After the first trigger member 132 pushes the driving member 141 to deviate from the equilibrium position, the second elastic member 143 can pull the driving member 141 to rotate relative to the support assembly 110, at least a part of the first trigger member 132 moves into the bayonet 142, and the driving member 141 can drive the first trigger member 132 to move, so that the triggering portion 130 moves towards the closed position.

[0095] In this embodiment, the structure of the actuating assembly 140 is defined. The actuating assembly 140 includes a driving member 141 and a plurality of second elastic members 143. The driving member 141 is rotatably mounted on the support assembly 110. The first trigger member 132 can be clamped to the driving member 141. One end of the second elastic member 143 is connected to the support assembly 110, and the other end is connected to the driving member 141. The second elastic member 143 can pull the driving member 141 to rotate relative to the support assembly 110, and then drive the first trigger member 132 to move through the driving member 141, so that the trigger member can move towards the closed position, achieving the technical effect of slow closing the door and automatically absorbing the closing of a small angle.

[0096] Specifically, as Figure 6 shown, when the triggering portion 130 is in the slow-closing position, the first trigger member 132 abuts against the driving member 141. At this time, the driving member 141 is in the equilibrium position, and the driving member 141 can overcome the pulling force of the second elastic member 143 to remain stationary. When the user applies a pushing force to the door body 220 in the direction towards the cabinet body 210, the first trigger member 132 can push the driving member 141 to rotate relative to the support assembly 110, and the driving member 141 deviates from the equilibrium position. Specifically, when the driving member 141 is in the equilibrium position, the extending directions of the plurality of second elastic members 143 are different, and the sizes of the plurality of second elastic members 143 are different, so that the plurality of second elastic members 143 generate pulling forces with different sizes and directions on the driving member 141. The pulling forces generated by the plurality of second elastic members 143 on the driving member 141 and the gravity of the driving member 141 itself overcome each other, so that the driving member 141 can remain stationary in the equilibrium position. The second elastic member 143 can be a spring.

[0097] Furthermore, as Figure 8As shown, after the driving member 141 deviates from the equilibrium position under the thrust of the first trigger member 132, the second elastic member 143 can pull the driving member 141 to rotate relative to the bracket assembly 110. The driving member 141 has a bayonet 142. As the driving member 141 rotates, at least a part of the first trigger member 132 moves into the bayonet 142, and the first trigger member 132 can be clamped in the bayonet 142 so that the driving member 141 can drive the first trigger member 132 to move, and further enable the trigger portion 130 to move towards the closed position, as Figure 10 shown. In this way, the technical effect of slowly closing the door and automatically absorbing the closing at a small angle can be achieved.

[0098] In some embodiments, optionally, as Figure 6 、 Figure 7 、 Figure 8 、 Figure 10 and Figure 13 shown, the pulling component 140 further includes: a swing block 144, which is installed on the driving member 141; a damper 146, which is installed on the bracket assembly 110, and the swing block 144 is connected to the damper 146. When the driving member 141 rotates relative to the bracket assembly 110, the damper 146 generates a resistance on the swing block 144 to slow down the rotation speed of the driving member 141.

[0099] In this embodiment, the structure of the pulling component 140 is further defined. The pulling component 140 further includes a swing block 144 and a damper 146. Among them, the swing block 144 is installed on the driving member 141, the damper 146 is installed on the bracket and connected to the swing block 144. The damper 146 can apply a resistance to the swing block 144 when the driving member 141 drives the swing block 144 to rotate, so that the trigger portion 130 can move smoothly, achieving the technical effect of slowly closing the door.

[0100] Specifically, as Figure 8 shown, after the user pushes the door body 220 to make the first trigger member 132 push the driving member 141 to deviate from the equilibrium position, the driving member 141 rotates relative to the bracket assembly 110 and drives the first trigger member 132 to move. During the process of the driving member 141 rotating relative to the bracket assembly 110, the driving member 141 drives the swing block 144 to rotate, the damper 146 generates a resistance on the swing block 144, and the swing block 144 transmits the resistance to the driving member 141. In this way, the rotation speed of the driving member 141 can be slowed down, and further the moving speed of the first trigger member 132 can be slowed down. Since the trigger portion 130 is installed on the door body 220, when the moving speed of the first trigger member 132 is slowed down, the closing speed of the door body 220 is slowed down, so that the technical effect of slowly closing the door can be achieved, avoiding damage to the door body 220 and the box body 210 caused by the too fast closing of the door body 220, and also avoiding too loud closing sound, improving the user experience.

[0101] In some embodiments, optionally, as Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 13 shown, the driving member 141 has a swing block groove 145, the swing block 144 is movably installed in the swing block groove 145, and there is a gap between the swing block 144 and the groove wall of the swing block groove 145.

[0102] In this embodiment, the installation method of the swing block 144 is defined. The driving member 141 has a swing block groove 145, and the swing block 144 is installed in the swing block groove 145. There is a gap between the swing block 144 and the groove wall of the swing block groove 145, and the swing block 144 can rotate or move relative to the driving member 141 in the swing block groove 145. Understandably, during the process of the driving member 141 driving the swing block 144 to rotate, since the swing block 144 is connected to the damper 146, the damper 146 will generate a resistance to the swing block 144, and the swing block 144 transmits the resistance to the driving member 141, and the pulling force of the second elastic member 143 overcomes the resistance transmitted by the swing block 144 to the driving member 141. If there is no gap between the swing block 144 and the swing block groove 145, then the swing block 144 will rotate synchronously with the driving member 141, which is likely to cause the swing block 144 to get stuck when the driving member 141 rotates to a certain position, and further cause the driving member 141 to not rotate normally. In order to prevent the swing block 144 from getting stuck in the swing block groove 145, this application leaves a gap between the swing block 144 and the groove wall of the swing block groove 145, so that the swing block 144 can rotate or move smoothly in the swing block groove 145.

[0103] In some embodiments, optionally, as Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 13 shown, the bracket assembly 110 has a damper receiving cavity 111, the damper 146 is movably installed in the damper receiving cavity 111, there is a gap between the damper 146 and the cavity wall of the damper receiving cavity 111, and the damper 146 can swing in the damper receiving cavity 111.

[0104] In this embodiment, the installation method of the damper 146 is defined. The bracket assembly 110 has a damper receiving cavity 111, and the damper 146 is movably installed in the damper receiving cavity 111. Specifically, when the driving member 141 rotates relative to the bracket assembly 110, the driving member 141 drives the swing block 144 to rotate, and the swing block 144 drives the damper 146 to swing in the damper receiving cavity 111. There is a gap between the damper 146 and the cavity wall of the damper receiving cavity 111. In this way, it is possible to prevent the cavity wall of the damper receiving cavity 111 from blocking the damper 146 when the damper 146 swings, thereby preventing the driving member 141 from getting stuck during rotation, ensuring that the triggering portion 130 can smoothly move between the slow closing position and the closing position, and further ensuring that the door body 220 can normally open and close the cabinet 210.

[0105] In some embodiments, optionally, as Figure 3 , Figure 7 , Figure 9 , Figure 12 , Figure 13 and Figure 14 shown, the door lock device 100 further includes: a second switch member 160, installed on the bracket assembly 110, and the second switch member 160 is used to open or close the monitoring circuit of the cooking appliance 200; a third triggering member 148, connected to the driving member 141, and during the process that the pulling assembly 140 drives the triggering portion 130 to move towards the closing position, the third triggering member 148 first triggers the second switch member 160, and then the second triggering member 133 triggers the first switch member 120.

[0106] In this embodiment, the structure of the door lock device 100 is further defined. The door lock device 100 further includes a second switch member 160 and a third triggering member 148. The cooking appliance 200 has a monitoring circuit, and the monitoring circuit is used to monitor whether the triggering portion 130 moves from the slow closing position to the closing position. The second switch member 160 is used to open or close the monitoring circuit of the cooking appliance 200, and the third triggering member 148 is used to trigger the second switch member 160.

[0107] Specifically, the second switch member 160 is installed on the bracket assembly 110, the third triggering member 148 is connected to the driving member 141, and the driving member 141 can drive the third triggering member 148 to move to trigger or shut down the second switch member 160. During the process that the pulling assembly 140 drives the triggering portion 130 to move towards the closing position, the driving member 141 rotates relative to the bracket assembly 110 under the pulling force of the second elastic member 143. During the rotation of the driving member 141, the driving member 141 drives the third triggering member 148 to move towards the second switch member 160. At the same time, the driving member 141 drives the first triggering member 132 to move, and the first triggering member 132 drives the second triggering member 133 to move towards the first switch member 120 through the rod assembly 131. AsFigure 9 As shown, in the process that the actuating assembly 140 drives the triggering portion 130 to move to the closed position, the third triggering member 148 first triggers the second switch member 160 , and then the second triggering member 133 triggers the first switch member 120 . Figure 9 The second switch 160 is shown in the dotted line range in the figure as the state in which the second switch 160 is triggered by the third trigger 148. That is, the second switch 160 is triggered first, and the monitoring circuit is turned on, indicating that the trigger unit 130 moves from the slow closing position to the door closing position, and the door body 220 is about to close the box body 210. Then the second trigger 133 triggers the first switch 120, the microwave generating circuit is turned on, and the cooking utensil 200 can generate microwaves under the control of the user. In this way, the cooking utensil 200 can generate microwaves after confirming that the door body 220 is about to close the box body 210, thereby preventing the cooking utensil 200 from generating microwaves when the door body 220 opens the box body 210, preventing microwaves from leaking, and improving the safety of the cooking utensil 200.

[0108] In some embodiments, optionally, Figure 3 As shown, the bracket assembly 110 includes: a frame body 112; an end cover 113, the frame body 112 and the end cover 113 together form an installation cavity, the driving member 141 and the pendulum block 144 are located in the installation cavity, the second switch member 160 is installed on the side of the end cover 113 away from the frame body 112, the end cover 113 is provided with a trigger opening 115, and the third trigger member 148 extends out of the trigger opening 115 and can move in the trigger opening 115.

[0109] In this embodiment, the structure of the bracket assembly 110 is defined. The bracket assembly 110 includes a frame body 112 and an end cover 113. The end cover 113 is detachably connected to the frame body 112. When the end cover 113 is connected to the frame body 112, the end cover 113 and the frame body 112 enclose an installation cavity, and the driving member 141 and the pendulum block 144 are located in the installation cavity. In this way, on the one hand, the driving member 141 and the pendulum block 144 can be protected, and on the other hand, the driving member 141 and the pendulum block 144 can be limited by the end cover 113.

[0110] Furthermore, the end cover 113 is provided with a trigger opening 115 so that the third trigger member 148 can trigger the second switch member 160. Specifically, the second switch member 160 is installed on the side of the end cover 113 away from the frame 112, that is, the second switch member 160 is located outside the installation cavity, which makes it easy to repair and replace the second switch member 160. The third trigger member 148 extends out of the trigger opening 115, and the driving member 141 can drive the third trigger member 148 to move in the trigger opening 115, so that the third trigger member 148 can trigger the second switch member 160.

[0111] In some embodiments, optionally, Figure 3 , Figure 7, Figure 9 , Figure 12 , Figure 13 and Figure 14 As shown in Figure 13 and Figure 14 , the door lock device 100 further includes: a third switch member 170, mounted on the bracket assembly 110; the actuating assembly 140 further includes: a swing rod 147, rotatably connected to the bracket assembly 110, and when the triggering portion 130 moves to the closed position, the first trigger member 132 pushes the swing rod 147 to rotate so that the swing rod 147 triggers the third switch member 170.

[0112] In this embodiment, the structure of the door lock device 100 is further defined. The door lock device 100 further includes a third switch member 170, which is mounted on the bracket assembly 110. When the trigger member moves to the closed position, the third switch member 170 is triggered, so that it can be confirmed that the trigger member is at the closed position at this time and the door body 220 has closed the box body 210. The actuating assembly 140 further includes a swing rod 147 for triggering the third switch member 170. The swing rod 147 is rotatably connected to the bracket assembly 110. When the triggering portion 130 moves to the closed position, the first trigger member 132 pushes the swing rod 147 to rotate, so that the swing rod 147 turns towards the third switch member 170 and triggers the third switch member 170. Figure 9 The state in which the third switch member 170 is triggered by the swing rod 147 within the dotted line range at the third switch member 170 is shown.

[0113] By providing the third switch member 170 in the door lock device 100 and the swing rod 147 in the actuating assembly 140, when the triggering portion 130 moves to the closed position, the first trigger member 132 can push the swing rod 147 to rotate, so that the swing rod 147 triggers the third switch member 170, and then it can be confirmed that the triggering portion 130 is at the closed position at this time and the door body 220 has closed the box body 210.

[0114] In some embodiments, optionally, during the process of the triggering portion 130 moving from the slow - closing position to the closed position, the second switch member 160, the first switch member 120, and the third switch member 170 are triggered in sequence.

[0115] In this embodiment, the triggering sequence of the first switch 120, the second switch 160 and the third switch 170 is defined. Specifically, in the process of the trigger part 130 moving from the slow closing position to the closed position, the second switch 160, the first switch 120 and the third switch 170 are triggered in sequence. It can be understood that the second switch 160 is triggered when the trigger part 130 moves from the slow closing position to the closed position. When the second switch 160 is triggered, the monitoring circuit of the cooking utensil 200 is turned on. The monitoring circuit is turned on, which means that the trigger part 130 moves from the slow closing position to the door closing position at this time, and the door body 220 is about to close the box body 210. When the first switch 120 is triggered, the microwave generating circuit of the cooking utensil 200 is turned on, and the cooking utensil 200 can generate microwaves. The third switch element 170 is triggered when the trigger portion 130 is located at the closed position. When the third switch element 170 is triggered, it can be confirmed that the trigger portion 130 is located at the closed position and the door body 220 has closed the box body 210 .

[0116] By enabling the second switch 160, the first switch 120 and the third switch 170 to be triggered in sequence during the process of the trigger part 130 moving from the slow closing position to the closed position, the cooking appliance 200 can be enabled to generate microwaves after confirming that the door 220 is about to close the box 210, thereby preventing the cooking appliance 200 from generating microwaves when the door 220 opens the box 210, preventing microwaves from leaking out, and improving the safety of the cooking appliance 200. It can also be confirmed that the trigger part 130 has moved to the closed position and the door 220 has closed the box 210 after the cooking appliance 200 has the ability to generate microwaves, so that the user can operate the cooking appliance 200.

[0117] In some embodiments, optionally, Figure 12 , Figure 13 and Figure 14 As shown, the trigger part 130 also includes: an unlocking member 137 connected to the side of the rod assembly 131 facing the outside, and the unlocking member 137 can drive the second trigger member 133 to rise, so that the second trigger member 133 is separated from the first switch member 120 and avoids the guide member 150.

[0118] In this embodiment, the structure of the triggering part 130 is further defined. The triggering part 130 also includes an unlocking member 137, which is connected to the side of the rod assembly 131 facing the outside. Specifically, the unlocking member 137 is exposed to the door body 220, so that the user can apply force to the unlocking member 137. Figure 12 As shown, when the user needs to unlock the door body 220 and the box body 210, the user can apply an upward force to the unlocking member 137 to lift the unlocking member 137. Figure 12The arrow in it shows the direction of the force applied by the user. Since both the unlocking member 137 and the second trigger member 133 are connected to the second rod member 135, the unlocking member 137 can drive the second trigger member 133 to rise through the second rod member 135. Thus, as Figure 14 shown, the second trigger member 133 can be separated from the first switch member 120 and avoid the guiding member 150. After the second trigger member 133 is separated from the first switch member 120, the first switch member 120 returns to the untriggered state, the microwave generating circuit is disconnected, and the cooking appliance 200 cannot generate microwaves. The unlocking member 137 drives the second trigger member 133 to rise to a position where it can avoid the guiding member 150 through the second rod member 135. At this time, the guiding member 150 can no longer stop and limit the second trigger member 133, and the door lock device 100 is in the unlocked state. The door body 220 and the box body 210 are unlocked, and then the user can pull the door body 220 outward to open the box body 210.

[0119] By arranging the unlocking member 137 in the trigger part 130, the user can complete the actions of unlocking the door body 220 and opening the door body 220 with a single hand operation. The user first raises the unlocking member 137 to enable the second trigger member 133 to avoid the guiding member 150 to unlock the door body 220 and the box body 210, and then pulls the door body 220 to open the box body 210. Both the unlocking and opening actions can be completed with a single hand, improving the user's convenience of use.

[0120] In some embodiments, optionally, during the process of the trigger part 130 moving from the closed position to the slow closing position, the first switch member 120, the third switch member 170, and the second switch member 160 are turned off in sequence.

[0121] In this embodiment, the turning-off sequence of the first switch member 120, the second switch member 160, and the third switch member 170 is defined. Specifically, during the process of the trigger part 130 moving from the closed position to the slow closing position, the first switch member 120, the third switch member 170, and the second switch member 160 are turned off in sequence. Understandably, during the process of the user opening the door body 220, the user needs to first raise the unlocking member 137 in the trigger part 130 to unlock the door body 220 and the box body 210. When the user raises the unlocking member 137, the unlocking member 137 drives the second trigger member 133 to be separated from the first switch member 120, and the first switch member is turned off, and the cooking appliance 200 cannot generate microwaves. When the second trigger member 133 rises to a position where it can avoid the guiding member 150, the guiding member 150 can no longer stop and limit the second trigger member 133. At this time, the door body 220 and the box body 210 are unlocked.

[0122] Further, after the door body 220 and the box body 210 are unlocked, the user continues to pull the door body 220 to open the box body 210, and the door body 220 drives the trigger part 130 to move from the closed position to the slow - closing position. During this process, the first trigger member 132 moves away from the third switch member 170 and the second switch member 160, and the swing rod 147 is first separated from the third switch member 170, and the third switch member 170 shuts down. Since the first trigger member 132 is clamped at the bayonet 142 of the driving member 141, during the process of the first trigger member 132 moving away from the second switch member 160, the first trigger member 132 drives the driving member 141 to rotate. After the third switch member 170 shuts down, the driving member 141 drives the third trigger member 148 to be separated from the second switch member 160, and the second switch member 160 shuts down.

[0123] By enabling the first switch member 120, the third switch member 170, and the second switch member 160 to shut down in sequence during the process of the trigger part 130 moving from the closed position to the slow - closing position, it can be ensured that the cooking appliance 200 loses the ability to generate microwaves before the user opens the door body 220, avoiding microwave leakage and enhancing the safety of the cooking appliance 200.

[0124] The second aspect of the present utility model further provides a cooking appliance 200, including: the door lock device 100 proposed in the first aspect of the present utility model; a box body 210 having a cooking cavity 211, and the bracket assembly 110 of the door lock device 100 is installed on the box body 210; a door body 220 rotatably connected to the box body 210, the door body 220 is used to open or close the cooking cavity 211, and the trigger part 130 of the door lock device 100 is installed on the door body 220.

[0125] The cooking appliance 200 provided by the present application includes a box body 210, a door body 220 and a door lock device 100. Among them, the box body 210 has a cooking cavity 211. The door body 220 is rotatably connected to the box body 210, and the door body 220 can open or close the box body 210 to open or close the cooking cavity 211. The door lock device 100 includes a bracket assembly 110 and a trigger portion 130. Among them, the trigger portion 130 is installed on the door body 220, and the bracket assembly 110 is installed on the box body 210. The door lock device 100 further includes a first switch member 120 and a pulling assembly 140, and the first switch member 120 and the pulling assembly 140 are installed on the bracket assembly 110. When the user closes the door body 220, the door body 220 is first pushed by the user to a position with a smaller included angle with the box body 210. At this time, the trigger portion 130 is driven by the door body 220 to the slow-close position. As the user continues to apply a pushing force to the door body 220, the trigger portion 130 pushes the pulling assembly 140 under the action of the pushing force, and the pulling assembly 140 can drive the trigger portion 130 to move from the slow-close position to the closed position. During the process of the trigger portion 130 moving to the closed position, the trigger portion 130 drives the door body 220 to rotate towards the box body 210 until the trigger portion 130 moves to the closed position, and the door body 220 closes the box body 210.

[0126] Further, during the process of the trigger portion 130 moving from the slow-close position to the closed position, the trigger portion 130 triggers the first switch member 120, and the microwave generation circuit of the cooking appliance 200 is turned on, and the cooking appliance 200 has the ability to generate microwaves.

[0127] The cooking appliance 200 provided in the second aspect of the present invention includes the door lock device 100 proposed in the first aspect of the present invention, and thus has all the beneficial effects of the door lock device 100.

[0128] The cooking appliance 200 can be a microwave oven, a microwave grill or a microwave steam oven.

[0129] In a possible embodiment, the microwave oven (i.e., the cooking appliance 200) heats the food by generating microwaves, such as Figure 1As shown, the microwave oven has a microwave generator and a cavity (i.e., a cooking cavity 211) for placing food. The cavity is equipped with an oven door (i.e., a door body 220) that can be opened, and the cavity is used to take in and put food. When the oven door is opened, the microwave generator does not work, and when the oven door is closed, the door opening and closing system (i.e., a door lock device 100) configured in the microwave oven includes an oven door hook (i.e., a triggering part 130) and an interlocking system (a pulling component 140 and a third triggering member 148), which triggers the monitoring switch (i.e., the second switch member 160), the primary switch (i.e., the first switch member 120) and the secondary switch (i.e., the third switch member 170) in sequence, so that the microwave oven can generate microwaves, and the user can control the generation of microwaves through the control panel to achieve the purpose of heating food. When the heating is completed and the oven door needs to be opened to take out the food, the primary switch, the secondary switch and the monitoring switch will be restored in sequence, so that the microwave generation circuit is disconnected.

[0130] like Figure 2 As shown, when the furnace door is closed, when the angle between the furnace door and the cavity front plate (i.e., the box front plate 212) is within a range of less than about 15°, under a relatively small door-pushing force (≤4N), the furnace door can automatically bring in the door hook through the rotating damping system (i.e., the pulling component 140), thereby forming an effect of automatically absorbing the door closing at a small angle.

[0131] The rotary damping system is installed at the lower part of the interlock bracket (i.e., the bracket assembly 110), and the rotary damping system is composed of a large tension spring and a small tension spring (i.e., the second elastic member 143) installed on the back of the interlock bracket, a driving lever (i.e., the driving member 141) installed in front of the interlock bracket, a swing block 144, a rotary lever (i.e., the swing rod 147), and a damper 146. The large tension spring and the small tension spring provide an inward door-closing pulling force during the door closing process, and the damper 146 plays a buffering or soft door closing effect during the door closing process. The driving lever is pulled by the large tension spring and the small tension spring, and during the door closing process, the lower door hook (i.e., the first trigger member 132) moves inward. At the same time, the swing block 144 is installed on the driving lever and can swing at a small angle, so that the damper 146 can adjust its posture appropriately with the rotation of the driving lever, so that the driving lever can rotate smoothly. Before the lower door hook closes the door in place (i.e., before the trigger part 130 moves to the closed position), the rotary lever can be pushed to trigger the secondary switch to turn on. The interlocking bracket includes a frame body 112 and an end cover 113. The end cover 113 covers the moving parts such as the driving lever, the pendulum block 144, the damper 146 and the rotating lever, so that the moving parts can rotate or move smoothly between the end cover 113 and the frame body 112, and the moving parts will not be axially separated. The monitoring switch is installed on the front side of the end cover 113 (i.e., the side away from the frame body 112). When the driving lever rotates, its protruding boss (i.e., the third trigger member 148) can touch the monitoring switch or restore the monitoring switch to a normally closed state.

[0132] The upper part of the interlocking bracket has a slope section (i.e., the guide member 150). The upper door hook (i.e., the second trigger member 133) crosses the slope section and controls the microwave generation circuit by touching and leaving the primary switch. When the upper door hook is in place, it triggers the primary switch to conduct the microwave generation circuit, and when the door hook leaves, the primary switch resumes to disconnect the microwave generation circuit.

[0133] During the process of closing the door, when the oven door is at a small angle with the cabinet 210, gently pushing the oven door with a force within 4N can make the oven door start to slowly close until the final closed state is reached. During this process, the oven door drives the upper door hook (i.e., the second trigger member 133) and the lower door hook (i.e., the first trigger member 132) to rotate into the cavity. At this time, the lower door hook first touches the driving lever of the rotary damping system, as Figure 5 shown. Under the inertial thrust of the oven door, the force balance state of the large tension spring and the small tension spring maintained at the entrance of the lower door hook is broken, causing the large tension spring and the small tension spring to rotate towards the inside of the cavity. Thereby driving the driving lever to rotate inwards, and then the driving lever pulls the lower door hook to move inwards.

[0134] As the stroke of the lower door hook moving inwards increases, the upper door hook also moves inwards following the rotation of the oven door. As Figure 7 shown, the hook head 138 of the upper door hook begins to touch the slope section of the interlocking bracket.

[0135] Finally, under the pulling force of the large tension spring and the small tension spring, the driving lever rotates, pushing the lower door hook to continue moving inwards. Furthermore, the lower door hook touches the rotary lever, causing the rotary lever to rotate by a small angle and then touching the secondary switch. And at this time, the upper door hook has crossed the slope section of the bracket under the thrust of the lower door hook and remains triggering the primary switch under the pressure of the upper door hook spring (i.e., the first elastic member 136). The state when the door is closed in place is as Figure 9 shown.

[0136] During the process of closing the door, first the driving lever rotates, and the convex platform (i.e., the third trigger member 148) rotates along with it, touching and pressing the monitoring switch installed on the end cover 113 to connect the monitoring switch circuit; subsequently, the upper door hook crosses the slope section of the interlocking bracket, and the vertical inner end face of the upper door hook and the slope section of the interlocking bracket form a locked state, that is, the child lock. Under the thrust of the spring of the upper door hook, it remains touching the primary switch to connect the microwave generation circuit. Finally, the lower door hook pushes the rotary lever to rotate by a small angle, touching and pressing the secondary switch to connect the secondary switch circuit. Thus, the microwave oven door opening and closing system is in the closed state, and the door hook remains triggering the monitoring switch, the primary switch, and the secondary switch, and the microwave generation circuit is in a controllable state.

[0137] During the door opening process, the upper door hook has a two-step door opening action, which is the unlocking process of the child lock function. First, the user lifts the tail hook of the upper door hook (i.e., the unlocking member 137) on the handle 221 of the oven door with one hand, so that the upper door hook can move upward by 4 mm to 10 mm. After the upper door hook is lifted, the hook head 138 is higher than the slope section of the interlock bracket. At the same time, because the upper door hook leaves, the primary switch returns to its original position and the microwave generating circuit is disconnected. Second, in the second step, the user pulls the handle 221 outward with one hand to open the oven door. At this time, the upper door hook is higher than the slope section of the interlock bracket and can be easily pulled out. At the same time, as the upper door hook is pulled out, the lower door hook is also pulled out outward. Only the horizontal component forces of the large tension spring and the small tension spring (less than 22 N) need to be overcome, and the lower door hook moves outward. The secondary switch contact automatically resets, driving the rotating lever to reset and disconnecting the secondary switch circuit. Finally, when the lower door hook is about to exit the front panel of the cavity, the lower door hook drives the lever back to the force balance position of the large tension spring and the small tension spring at the entrance. The driving lever stops at the balance position. At this time, the convex platform of the driving lever (i.e., the third triggering member 148) has fallen off the trigger of the monitoring switch on the end cover 113, and the monitoring switch circuit remains normally closed to prevent the accidental conduction of the microwave generating circuit. After both the lower door hook and the upper door hook are removed from the front panel of the cavity, the oven door opening process is completed, and the microwave generating circuit is disconnected and in a monitoring and protection state.

[0138] During the door opening and closing process, the movement of the upper door hook is as Figure 12 , Figure 13 and Figure 14 shown. When closing the door, as the lower door hook is pushed inward by the driving lever, the upper door hook also moves inward. When the hook head 138 touches the slope section of the interlock bracket, the upward reaction force of the slope section causes the upper door hook to move upward. Because the lower end of the second rod 135 and the upper end of the first rod 134 are nested with each other to form a sliding pair, the upper door hook can only slide up and down on the oven door and will not rotate or shift forward and backward. When the upper door hook is driven over the slope section of the interlock bracket, the thrust of the compression spring enables the upper door hook to continuously press the primary switch. At the same time, the vertical inner end surface of the hook head 138 of the upper door hook forms a lock with the slope section of the interlock bracket, and the direct door opening force must be greater than 45 N to ensure the reliability of the child lock. When opening the door, the first step is that the user lifts the tail hook of the upper door hook on the handle 221 by hand, so that the hook head 138 of the upper door hook is higher than the slope section of the interlock bracket. The second step is to pull the handle on the oven door outward with the hand to open it. The upper door hook is pulled out as the oven door rotates outward. At this time, the child lock is released, and the two-step door opening process is completed.

[0139] The middle section of the slope section cross-section of the interlock bracket (i.e., the second guiding surface 152) adopts a convex curve type. When the upper door hook touches the slope section during door closing, it is located at the end of this convex curve. The convex curve can ensure that the upper door hook smoothly crosses over. The end of the slope section cross-section of the interlock bracket (i.e., the third guiding surface 153) adopts a relatively short straight line (about 3 mm to 6 mm) tangent to the convex curve in the middle section, ensuring a smooth connection of the curve while reducing the climbing distance of the upper door hook. The front section of the slope section of the interlock bracket (i.e., the first guiding surface 151) adopts a plane, an inclined plane or a concave curved surface to avoid the upper door hook, so that when the upper door hook touches the convex curve in the middle section, there is a gap of 1 mm to 5 mm between the front section and the lower end of the door hook.

[0140] Compared with the existing products, for the microwave oven proposed in this application, the travel of the upper door hook when touching the slope section of the interlock bracket is delayed by 3 mm to 8 mm, and the damper 146 can rotate 9° to 13° more, the climbing force provided to the upper door hook is increased by 5 N to 8 N, with an increase rate of more than 20%, and the success rate of absorbing the slow door closing and small-angle automatic door closing is increased by more than 35%.
