Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a cooking utensil. Background Art

[0002] Related art microwave ovens are equipped with a push-door mechanism for opening the oven door. This mechanism includes a drive unit, a gear reduction device, an ejection assembly, and a push rod. Upon receiving a door-opening command, the push rod is ejected, opening the oven door. However, this type of push-door mechanism requires a high-power drive unit, a complex transmission mechanism, and high costs. The push rod has a long stroke, resulting in a long door opening time. Furthermore, when the oven door glass is heated, the push rod's thrust can locally cause the glass to crack. Summary of the Invention

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

[0004] To this end, the present invention provides a cooking utensil.

[0005] To achieve at least one of the above-mentioned purposes, the present invention proposes a cooking appliance, comprising: a box body; a door body rotatably connected to the box body, the door body being used to open or close the box body, and the door body having a hook seat; a door lock device installed on the box body, the door lock device being used to lock the door body to the box body, the door lock device comprising: a bracket installed on the box body; a rotating rod hinged to the bracket, when the door body closes the box body, the rotating rod is connected to the hook seat to lock the door body to the box body; a driving assembly installed on the bracket, the driving assembly pushes the rotating rod to rotate in a first direction after receiving a door opening command, the rotating rod is separated from the hook seat to unlock the door body from the box body; a push rod installed on the bracket, after the rotating rod is separated from the hook seat, the push rod extends in a direction toward the door body to push the door body to rotate in a direction away from the box body to a first open position.

[0006] The present application proposes a cooking appliance comprising a housing and a door. The housing is adapted to hold food ingredients, and the door is rotatably connected to the housing, enabling the door to open and close the housing. The cooking appliance further comprises a door lock device mounted on the housing, with a hook seat provided on the door, capable of being connected to and disconnected from the hook seat. When the door lock device is connected to the hook seat, the door closes the housing and is locked to the housing. When the door lock device is disconnected from the hook seat, the door opens the housing. Upon receiving a command to open the door, the door lock device automatically opens the door, eliminating the need for manual operation by the user.

[0007] Furthermore, the door lock device includes a bracket and a rotating rod, wherein the bracket is mounted on the box body, the rotating rod is hinged to the bracket, and the rotating rod can rotate around the hinge point between the rotating rod and the bracket so that the bracket forms a lever structure. The rotating rod can be connected to the hook seat, and when the door body closes the box body, the rotating rod is connected to the hook seat to lock the door body to the box body. Furthermore, the door lock device also includes a driving assembly, which can apply a thrust to one end of the rotating rod so that the rotating rod rotates around the hinge point, and the other end of the rotating rod can be connected to or separated from the hook seat. When the rotating rod rotates, the rotating rod and the hook seat can be connected or separated. Specifically, after the driving assembly receives the door opening command, the driving assembly pushes the rotating rod to rotate in the first direction, and separates from the hook seat during the process of the rotating rod rotating in the first direction, at which time the door body and the box body are unlocked.

[0008] Furthermore, the door lock device also includes a push rod, which is mounted on the bracket. When the door body closes the box body, the push rod is subjected to a thrust in the direction toward the door body. When the door body is locked to the box body, the end of the push rod abuts the door body, and the door body can stop the push rod to maintain the push rod in its initial position. After the rotating rod is separated from the hook seat, the door body and the box body are unlocked, and the door body no longer stops the push rod. The push rod extends in the direction toward the door body under the action of the thrust, and the push rod pushes the door body to rotate away from the box body until the door body rotates to the first open position, thereby achieving automatic door opening. When the door body is in the first open position, the angle between the door body and the box body is small, at this time the angle between the door body and the box body is within the range of 0° to 5°, and the stroke of the push rod is short.

[0009] By providing a drive assembly, a rotating rod, and a push rod in the door lock device, the drive assembly automatically pushes the rotating rod to rotate upon receiving a door opening command, thereby separating the hook provided on the rotating rod from the hook seat provided on the door body, thereby unlocking the door body and the cabinet. The push rod is no longer limited by the door body, allowing the push rod to push the door body to open the cabinet, thereby achieving automatic door opening of the cooking appliance. This eliminates the need for a handle on the door body, ensuring a good integration between the door body and the cabinet in which the cooking appliance is installed, and improving the aesthetics of the cooking appliance. Furthermore, the present application can unlock the door body and the cabinet solely by pushing the rotating rod through the drive assembly, eliminating the need for a complex door lock structure and reducing product costs. Furthermore, the push rod pushes the door body to rotate when the door body and the cabinet are already unlocked, eliminating the risk of door deformation or glass cracking on the door body.

[0010] In some technical solutions, optionally, the rotating rod has a hook body, and the hook body can be connected to or separated from the hook seat.

[0011] In the technical solution, the structure of the rotating rod is limited. The end of the rotating rod for connecting with the hook base has a hook body matched with the hook base. The hook body can be matched with the hook base to lock the door body to the box body or unlock the door body from the box body. Specifically, the hook body can be connected or separated from the hook base. When the hook body is connected to the hook base, the door body closes the box body and is locked to the box body. When the hook body is separated from the hook base, the door body is unlocked from the box body, and the door body can be pushed to open the box body. After the driving assembly receives an open-door instruction, the driving assembly pushes the rotating rod to rotate in a first direction. During the rotation of the rotating rod in the first direction, the hook body is separated from the hook base, and the door body is unlocked from the box body.

[0012] By arranging the hook body at one end of the rotating rod, the locking or unlocking of the door body can be achieved by matching the hook body with the hook base.

[0013] In some technical solutions, the door lock device further comprises a first elastic member installed on the bracket. One end of the first elastic member abuts against the rotating rod. When the door body closes the box body, the first elastic member is in a compressed state. The first elastic member applies a pushing force to the rotating rod to keep the hook body connected to the hook base.

[0014] In the technical solution, the structure of the door lock device is further limited. The door lock device further comprises a first elastic member. The first elastic member is used to provide a pre-tightening force to the hook body to firmly connect the hook body to the hook base. Specifically, the first elastic member is installed on the bracket. The driving assembly contacts the upper surface of the end of the rotating rod away from the hook body. The first elastic member contacts the lower surface of the end of the rotating rod away from the hook body. When opening the door, the driving assembly pushes the rotating rod to rotate in a first direction to separate the hook body from the hook base. When the door body closes the box body, the first elastic member applies a pushing force to the rotating rod. The rotating rod has a tendency to rotate in a second direction under the pushing force of the first elastic member. The second direction is opposite to the first direction. Since the hook body is connected to the hook base in the closed door state, the hook body cannot rotate in the second direction. Therefore, the first elastic member provides a pre-tightening force to the hook body. The hook body is firmly connected to the hook base under the pre-tightening force.

[0015] By arranging the first elastic member abutting against the rotating rod in the door lock device, the hook body can generate a pre-tightening force to the hook base under the pushing force of the first elastic member to the rotating rod, so that the door hook is firmly connected to the hook base.

[0016] In some technical solutions, the bracket has a mounting rack for mounting the first elastic member. The rotating rod has a positioning member. One end of the first elastic member is installed on the positioning member.

[0017] This technical solution further defines the structure of the door lock device. It includes a structure for mounting and positioning the first elastic member. Specifically, the bracket includes a mounting bracket, to which the first elastic member is mounted. The mounting bracket can be cylindrical or a plate protruding from the bracket. A positioning member is provided on the rotating rod, to which the end of the first elastic member that abuts the rotating rod is mounted, thereby ensuring the installation and positioning of the first elastic member.

[0018] In a possible technical solution, the first elastic member is a spring, the positioning member is a column structure, and the positioning member is inserted into the first elastic member.

[0019] By arranging the mounting bracket on the bracket and the positioning piece on the rotating rod, the first elastic piece can be installed and positioned by the mounting bracket and the positioning piece, thereby improving the stability of the first elastic piece.

[0020] In some technical solutions, the cooking appliance optionally further includes: a cooking assembly mounted on the housing, the cooking assembly being used to heat food; a monitoring circuit electrically connected to the cooking assembly, wherein when the monitoring circuit is disconnected, the cooking assembly can be powered on, and when the monitoring circuit is connected, the cooking assembly is short-circuited; the door lock device further includes: a first switch mounted on the bracket, the first switch being used to control the monitoring circuit to be turned on or off; and a second switch being mounted on the bracket, the second switch being used to control the cooking assembly to be powered on or off; wherein, when the door body closes the housing, the driving assembly maintains a triggering state on the first switch member to disconnect the monitoring circuit, and the push rod maintains a triggering state on the second switch member to enable the cooking assembly to be powered on; after the door lock device receives a door opening command, the driving assembly pushes the rotating rod to rotate in a first direction to a first position and a second position in sequence; when the rotating rod is in the first position, the driving assembly separates from the first switch member to enable the monitoring circuit to be turned on; when the rotating rod is in the second position, the hook body separates from the hook seat, and then as the push rod extends in a direction toward the door body, the push rod separates from the second switch member, and the cooking assembly is powered off.

[0021] In this technical solution, the structure of the door lock device is further defined. The cooking appliance includes a cooking component and a monitoring circuit. The cooking component is used to cook food, and the monitoring circuit is used to control the power supply status of the cooking component. Specifically, the cooking component is mounted on a housing. When the cooking component is in operation, it heats and cooks food within the housing. The monitoring circuit is electrically connected to the cooking component. When the monitoring circuit is disconnected, the cooking component can be powered and operated. When the monitoring circuit is connected, the cooking component is short-circuited and cannot operate.

[0022] Furthermore, the door lock device also includes a first switch and a second switch, each of which is used to control the on / off state of the monitoring circuit and the power supply status of the cooking component. Specifically, the first switch is mounted on the bracket and is a normally closed microswitch. When the first switch is triggered, the monitoring circuit is disconnected, allowing the cooking component to receive power. When the first switch is not triggered, the monitoring circuit is connected, short-circuiting the cooking component, and preventing it from receiving power. The second switch is mounted on the bracket and is a normally open microswitch. When the second switch is triggered, the cooking component can receive power and operate normally to heat food. When the second switch is not triggered, the cooking component is powered off and stops operating.

[0023] Furthermore, the first switch is triggered by the drive assembly, and the second switch is triggered by the push rod. When the door closes the cabinet, the drive assembly maintains the triggering state of the first switch, thereby keeping the monitoring circuit disconnected. This allows the cooking component to remain powered and operate normally under user control. Simultaneously, the push rod maintains the triggering state of the second switch, thereby maintaining the power supply to the cooking component and allowing it to operate normally.

[0024] Furthermore, after the door lock device receives the door opening command, the drive assembly pushes the rotating rod to rotate in the first direction to the first position and the second position in sequence. When the rotating rod is in the first position, the drive assembly is separated from the first switch member. At this time, the first switch member is not triggered, the monitoring circuit is connected, and the cooking assembly is short-circuited. The rotating rod is then rotated to the second position, at which time the hook body is separated from the hook seat, and the door body and the housing are unlocked. In other words, the cooking assembly has stopped running before the door body and the housing are unlocked. It is understandable that when the door body opens the housing, if the cooking assembly remains in operation, it is easy for microwaves in the housing to leak out, or high-temperature steam in the housing to overflow, which can easily cause burns to the user. Therefore, the cooking appliance proposed in this application has stopped the cooking assembly before the door body and the housing are unlocked, thereby improving the safety of the cooking appliance.

[0025] Furthermore, after the door and the housing are unlocked, the push rod extends toward the door. As the push rod extends toward the door, it separates from the second switch, deactivating the second switch. At this point, the cooking component is powered off, ensuring it stops operating. As the push rod extends toward the door, it pushes the door to open the housing, creating a gap between the housing and the door. Since the cooking component is now stopped, microwaves or high-temperature steam within the housing are prevented from escaping and potentially harming the user, further enhancing the safety of the cooking appliance.

[0026] In some technical solutions, optionally, the door lock device also includes: a spring, installed on a first switch member, the first switch member has a first trigger point, when the door body closes the box body, the driving component pushes the spring to squeeze the first trigger point, when the driving component pushes the rotating rod to rotate to the first position, the driving component separates from the spring, and the spring is separated from the first trigger point.

[0027] In this technical solution, the structure of the door lock device is further defined. The door lock device also includes a spring, and the driving assembly can trigger the first switch member through the spring. Specifically, the first switch member has a first trigger point. When the first trigger point is squeezed, the first switch member is triggered, and when the first trigger point is not squeezed, the first switch member is not triggered. The spring is installed on the first switch member, and the spring is adjacent to the first switch member. When the spring is not squeezed by an external force, there is a gap between the spring and the first trigger point, and the first trigger point is not squeezed. When the door body closes the box body, the driving assembly contacts the spring and applies a squeezing force to the spring. Under the action of the driving assembly, the spring moves in the direction toward the first trigger point and squeezes the first trigger point. The first switch member is triggered, the monitoring circuit is disconnected, and the cooking assembly is not short-circuited, so that the cooking assembly can start normally.

[0028] Furthermore, after the driving component receives the door opening command, when the driving component pushes the rotating rod to rotate to the first position, the driving component is separated from the spring, the spring is no longer squeezed by the driving component, and the spring returns to a natural state without force. At this time, the spring is separated from the first trigger point, the first switch is not triggered, the monitoring circuit is turned on, the cooking component is short-circuited, and the cooking component cannot operate.

[0029] By arranging a spring sheet in the door lock device, the driving component can trigger the first switch component by applying an extrusion force to the spring sheet, and the driving component can be separated from the spring sheet to prevent the first switch component from being triggered, thereby enabling the cooking component to be short-circuited or connected to electricity according to the state of the door switch.

[0030] In some technical solutions, optionally, the push rod includes: an extrusion section; an avoidance section, connected to the extrusion section, and the diameter of the avoidance section is smaller than the diameter of the extrusion section; wherein, the second switch member has a second trigger point, when the door body closes the box body, the extrusion section squeezes the second trigger point, and when the door body opens the box body, the avoidance section moves to the position of the second trigger point, and the avoidance section avoids the second trigger point.

[0031] In this technical solution, the structure of the push rod is defined. The push rod has a multi-section, variable-diameter structure, comprising a pressing section and an escape section. The pressing section is used to trigger the second switch member, and the escape section is used to restore the second switch member to an untriggered state. The diameter of the pressing section is larger than that of the escape section. Specifically, the second switch member has a second trigger point. When the second trigger point is pressed, the second switch member is triggered; when the second trigger point is not pressed, the second switch member is not triggered. When the door closes the cabinet, the pressing section moves to the position of the second trigger point. Due to the larger diameter of the pressing section, the pressing section can press the second trigger point, triggering the second switch member and enabling power to the cooking component. When the door opens, as the push rod moves toward the door, the escape section moves to the position of the second trigger point. Due to the smaller diameter of the escape section, the escape section cannot contact the second trigger point, resulting in the second trigger point not being pressed, the second switch member not being triggered, and the cooking component being powered off.

[0032] By setting the push rod to a multi-section structure with different diameters, the second switch member can be triggered and non-triggered when the push rod moves, without setting other complex structures, thereby reducing the production cost of the door lock device.

[0033] In some technical solutions, optionally, the cooking assembly includes at least one of a heating element, a steam generating device, and a microwave generating device.

[0034] In this technical solution, a cooking assembly is defined. It includes at least one of a heating element, a steam generator, or a microwave generator. For example, if the cooking appliance is a microwave oven, the cooking assembly includes a microwave generator; if the cooking appliance is a steam-bake combination oven, the cooking assembly includes both a heating element and a steam generator.

[0035] In some technical solutions, optionally, the driving assembly includes: a motor, installed on a bracket; a driving member, installed on the bracket, the motor and the driving member are respectively located on both sides of the bracket, and the motor drives the driving member to rotate; wherein, the rotating rod has a first mating surface, and the driving member can contact the first mating surface.

[0036] In this technical solution, the structure of the drive assembly is defined. The drive assembly includes a motor and a driver, both of which are mounted on a bracket. The motor and driver are connected to each other, and when the motor is running, the driver can rotate under the influence of the motor. The driver can be a cam. The motor and driver are respectively mounted on opposite sides of the bracket. The driver, the rotating rod, the first switch member, the second switch member, and the push rod are located on the same side of the bracket, while the motor is located on the other side of the bracket to prevent interference between the motor and other components of the door lock device.

[0037] Furthermore, the rotating rod has a first mating surface configured to engage a driving member, which can contact the first mating surface to drive the rotating rod to rotate. Specifically, when the motor receives a door opening command, the motor begins to operate, driving the driving member to rotate. The driving member may be a cam, and a protruding side of the driving member rotates to a position where it contacts the first mating surface. As the driving member continues to rotate, the driving member pushes the rotating rod in a first direction, thereby separating the hook body from the hook seat on the door body, thereby unlocking the door body and the box body. The first mating surface may be a flat surface.

[0038] By arranging a first mating surface on the rotating rod that cooperates with the driving member, the driving member can more easily apply a thrust to the rotating rod, so that the rotating rod is subjected to a stable force to rotate.

[0039] In some technical solutions, optionally, the door lock device also includes: a second elastic member installed on the push rod, when the door body closes the box body, the second elastic member is compressed, when the door body and the box body are unlocked, the second elastic member pushes the push rod to move in the direction toward the door body.

[0040] In this technical solution, the structure of the door lock device is further defined. The door lock device also includes a second elastic member, which is used to push the push rod to move. Specifically, the second elastic member is installed on the push rod, the push rod has a boss structure, the bracket has a table for limiting, and the two ends of the second elastic member are respectively against the table on the bracket and the boss on the push rod. When the door body closes the box body, the push rod is squeezed by the door body, and the door body pushes the push rod to move in the direction toward the inside of the box body, and the second elastic member is compressed, and the second elastic member has a thrust on the push rod in the direction toward the door body. When the door body is unlocked from the box body, the second elastic member pushes the push rod to move in the direction toward the door body, so that the push rod can push the door body to open the box body, thereby realizing automatic door opening. The second elastic member can be a spring.

[0041] By arranging a second elastic member in the door lock device, the push rod can be pushed to move by the second elastic member, thereby realizing automatic door opening.

[0042] In some technical solutions, optionally, when the hook body is connected to the hook seat, the rotating rod is in a third position, and the door lock device further includes: a limit member connected to the bracket, and the rotating rod has a second mating surface. When the rotating rod is in the third position, the limit member cooperates with the second mating surface to prevent the rotating rod from rotating in a second direction, and the second direction is opposite to the first direction.

[0043] In this technical solution, the door lock device is further defined. The door lock device also includes a stopper, and the rotating rod has a second mating surface that mates with the stopper. The stopper and the second mating surface mate to achieve a stop and limit effect on the rotating rod. Specifically, when the hook body is connected to the hook seat, the door body and the box body are locked, and the rotating rod is in a third position. When the rotating rod is in the third position, the stopper abuts the second mating surface. The second mating surface is flat, and the stopper has a certain width. Under the action of the stopper, the second mating surface cannot rotate in a second direction opposite to the first direction, thereby maintaining the rotating rod in the third position.

[0044] In some technical solutions, optionally, after the door body and the box body are unlocked and the box body is opened, the rotating rod can be restored to the third position. In the process of the door body closing the box body, the hook body first contacts the hook seat and moves along the surface of the hook seat until the door body closes the box body, the hook body is connected to the hook seat, and the rotating rod rotates to the third position again.

[0045] In this technical solution, the door closing process is defined. During the process of the door body opening the box, the rotating rod needs to deviate from the third position to separate the hook body from the hook seat, thereby unlocking the door body and the box. When the door body and the box are unlocked and the door body opens the box, the rotating rod can return to the third position. When the user needs to close the door, the user pushes the door body toward the box. During the door closing process, the hook body first contacts the hook seat on the door body. As the door body rotates toward the box, the hook body moves along the surface of the hook seat until the door body closes the box. The hook body is connected to the hook seat to lock the door body to the box. At this time, the rotating rod is rotated to the third position again. In this way, the door body and the box can be automatically locked when closing the door.

[0046] In some technical solutions, optionally, the side of the hook seat facing the box body has a guiding slope, and the side of the hook body facing the door body has a curved surface.

[0047] This technical solution defines the structure of the hook seat and hook body. The hook seat has a curved surface on the side facing the box, and a guide slope on the side facing the box. As the door closes the box, the curved surface of the hook body moves along the guide slope of the hook seat until the hook body is connected and locked with the hook seat. Specifically, when the door closes the box, the door rotates toward the box, and the curved surface on the hook body first contacts the guide slope on the hook seat. As the door continues to rotate toward the box, the curved surface on the hook body slides upward along the guide slope until the door is fully closed, the curved surface separates from the guide slope, and the hook body is locked to the hook seat.

[0048] The guide bevel has a guiding function, and the arc surface also has the function of reducing friction. By setting a arc surface at the end of the hook body and setting a guide bevel on the side of the hook seat facing the box body, the friction between the hook body and the hook seat can be reduced through the cooperation of the guide bevel and the arc surface, so that the hook body and the hook seat can be connected more smoothly, reducing the user's resistance to closing the door.

[0049] In some technical solutions, optionally, the hook body further has an extrusion slope, which is located on the side of the arc surface facing away from the door body. When the door body closes the box body, an angle is formed between the extrusion slope and the guide slope.

[0050] In this technical solution, the structure of the hook body is further defined. The hook body also has an extrusion bevel, located on the side of the curved surface facing away from the door body, with an angle between the extrusion bevel and the horizontal plane ranging from 55° to 70°. The guide bevel on the hook seat forms an angle with the horizontal plane, with an angle between the guide bevel and the horizontal plane ranging from 20° to 35°. When the door closes the box body, the extrusion bevel and the guide bevel form an angle ranging from 75° to 105°, which enables the rotating rod to apply an extrusion force on the door body toward the interior of the box body, with the extrusion force ranging from 35N to 60N.

[0051] In some technical solutions, optionally, the rotating rod further has an avoidance groove, which is arranged adjacent to the hook body and is used to avoid the hook seat.

[0052] This technical solution further defines the structure of the rotating lever. The rotating lever also includes a clearance groove, located adjacent to the hook body and on the side of the hook body facing away from the door body. This allows the hook body to form a hook-shaped structure. When the hook body is connected to the hook seat, the protruding structure of the hook seat can penetrate into the clearance groove, allowing the clearance groove to clear the hook seat, thus locking the hook body to the hook seat and connecting the hook body to the hook seat.

[0053] In some technical solutions, optionally, the cooking appliance also includes: at least two hinge devices, respectively installed on both sides of the door body, the hinge devices are used to rotatably connect the door body to the box body, and at least one of the at least two hinge devices has a damping assembly; after the push rod pushes the door body to the first open position, the door body can continue to rotate under the action of gravity, and when the door body rotates to the second open position, the damping assembly generates rotational resistance to the door body.

[0054] In this technical solution, the structure of the cooking appliance is further defined. The cooking appliance also includes at least two hinge devices, through which the door body is rotatably connected to the door body, and the hinge devices can also realize further automatic opening of the door body. Specifically, the at least two hinge devices are respectively installed on both sides of the door body to ensure that the overall force on the door body is balanced. At least one of the at least two hinge devices has a damping assembly. When the door body is further opened, the damping assembly can generate resistance to the door body to slow down the door body's rotation speed.

[0055] Specifically, during the automatic door opening process of the cooking appliance, when the door body rotates to the first position, the push rod no longer extends. At this time, the door body can continue to rotate in the direction away from the box body under the action of its own gravity, and the opening angle of the door body continues to increase until the door body rotates to the second open position. In one possible technical solution, when the door body is in the second open position, the angle between the door body and the box body is 45° to 55°. Furthermore, when the door body rotates to the second position, the damping assembly generates rotational resistance to the door body. The door body continues to rotate under the action of gravity to open the box body, but due to the action of the damping assembly on the door body, the door body rotates slower under the action of the rotational resistance to achieve the effect of slowly opening the door.

[0056] In one possible technical solution, there are two hinge devices, one mounted on either side of the door body, with one hinge device having a damping assembly and the other not. This can reduce the production cost of the cooking appliance while achieving a slow-opening door.

[0057] By incorporating a hinge device with a damping component into the cooking appliance, the damping component can slow down the door's opening speed, achieving a slow-opening effect and improving the user experience. Furthermore, the push rod rotates the door only when the door and the cabinet are unlocked, eliminating the risk of door deformation or glass cracking.

[0058] In some technical solutions, optionally, the cooking appliance further includes: a control panel installed on the housing, and the control panel is electrically connected to the driving assembly.

[0059] In this technical solution, the structure of the cooking appliance is further defined. The cooking appliance also includes a control panel for controlling the operation of the cooking appliance through the control panel. Specifically, the control panel is mounted on the housing and exposed to the outside of the housing. The control panel and the door body are located on the same side, so that the user can input control instructions through the control panel. The control panel is electrically connected to the drive assembly. When the door body needs to be opened, the user inputs the door opening command through the control panel. After receiving the door opening command, the drive assembly starts to operate, and the drive assembly pushes the rotating rod to rotate in the first direction until the hook body is separated from the hook seat. At this time, the door body and the housing are unlocked. Then the push rod automatically moves in the direction toward the door body, pushing the door body to open the housing, thereby realizing automatic door opening.

DETAILED DESCRIPTION

[0080] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0081] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0082] The following refers to Figures 1 to 14 The cooking utensil 100 provided according to some embodiments of the present application is described.

[0083] In an embodiment according to the present application, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 10 and Figure 11As shown, the present application proposes a cooking appliance 100, comprising: a box body 110; a door body 120, rotatably connected to the box body 110, the door body 120 is used to open or close the box body 110, and the door body 120 has a hook seat 121; a door lock device 130, installed on the box body 110, the door lock device 130 is used to lock the door body 120 to the box body 110, and the door lock device 130 includes: a bracket 131, installed on the box body 110; a rotating rod 140, hinged to the bracket 131, when the door body 120 closes the box body 110, the rotating rod 140 is connected to the bracket 131. The hook seat 121 is used to lock the door body 120 to the box body 110; the driving component 132 is installed on the bracket 131. After receiving the door opening command, the driving component 132 pushes the rotating rod 140 to rotate in the first direction, and the rotating rod 140 is separated from the hook seat 121 to unlock the door body 120 from the box body 110; the push rod 170 is installed on the bracket 131. After the rotating rod 140 is separated from the hook seat 121, the push rod 170 extends in the direction toward the door body 120 to push the door body 120 to rotate in the direction away from the box body 110 to the first open position.

[0084] This application provides a cooking appliance 100, comprising a housing 110 and a door 120. The housing 110 can hold food, and the door 120 is rotatably connected to the housing 110, enabling the door 120 to open or close the housing 110. The cooking appliance 100 also includes a door lock 130, which is mounted on the housing 110. The door 120 is provided with a hook seat 121, and the door lock 130 can be connected to or disconnected from the hook seat 121. When the door lock 130 is connected to the hook seat 121, the door 120 closes the housing 110 and locks to the housing 110. When the door lock 130 is disconnected from the hook seat 121, the door 120 opens the housing 110. Upon receiving a door opening command, the door lock 130 automatically opens the door 120, eliminating the need for manual operation by the user.

[0085] Furthermore, the door lock device 130 includes a bracket 131 and a rotating rod 140. The bracket 131 is mounted on the housing 110, and the rotating rod 140 is hinged to the bracket 131. The rotating rod 140 can rotate about the hinge point between the rotating rod 140 and the bracket 131, so that the bracket 131 forms a lever structure. The rotating rod 140 can be connected to the hook seat 121. When the door 120 closes the housing 110, the rotating rod 140 is connected to the hook seat 121 to lock the door 120 to the housing 110.

[0086] Furthermore, the door lock device 130 also includes a drive assembly 132, which can apply a thrust to one end of the rotating rod 140 to rotate the rotating rod 140 about the hinge point. The other end of the rotating rod 140 can be connected to or separated from the hook seat 121. Therefore, when the rotating rod 140 rotates, the rotating rod 140 can be connected to or separated from the hook seat 121. Specifically, after the drive assembly 132 receives the door opening command, the drive assembly 132 pushes the rotating rod 140 to rotate in a first direction. During the process of rotating the rotating rod 140 in the first direction, the rotating rod 140 separates from the hook seat 121, and the door body 120 and the box body 110 are unlocked.

[0087] Furthermore, the door lock device 130 also includes a push rod 170, which is mounted on the bracket 131. When the door body 120 closes the box body 110, the push rod 170 is subjected to a thrust in the direction toward the door body 120. When the door body 120 is locked to the box body 110, the end of the push rod 170 abuts against the door body 120, and the door body 120 can stop the push rod 170 to keep the push rod 170 in the initial position. After the rotating rod 140 is separated from the hook seat 121, the door body 120 is unlocked from the box body 110, and the door body 120 no longer stops the push rod 170. The push rod 170 extends in the direction toward the door body 120 under the action of the thrust, and the push rod 170 pushes the door body 120 to rotate in the direction away from the box body 110 until the door body 120 rotates to the first open position, thereby realizing automatic door opening. Figure 12 As shown, when the door body 120 is located at the first open position, the angle between the door body 120 and the box body 110 is small. At this time, the angle between the door body 120 and the box body 110 is in the range of 0° to 5°, and the stroke of the push rod 170 is short.

[0088] By providing a drive assembly 132, a rotating rod 140, and a push rod 170 within the door lock device 130, the drive assembly 132 automatically rotates the rotating rod 140 upon receiving a door opening command, disengaging the hook 141 provided on the rotating rod 140 from the hook seat 121 provided on the door body 120, thereby unlocking the door body 120 from the cabinet 110. The push rod 170 is no longer restrained by the door body 120, allowing it to push the door body 120 to open the cabinet 110, thereby automatically opening the cooking appliance 100. This eliminates the need for a handle on the door body 120, ensuring a seamless integration between the door body 120 and the cabinet in which the cooking appliance 100 is installed, and enhancing the aesthetics of the cooking appliance 100. Furthermore, the present invention unlocks the door body 120 from the cabinet 110 solely through the drive assembly 132 pushing the rotating rod 140, eliminating the need for a complex door lock structure and reducing product costs. Furthermore, the push rod 170 pushes the door body 120 to rotate when the door body 120 and the box body 110 are unlocked, and there is no risk of deformation of the door body 120 and bursting of the glass on the door body 120. In some embodiments, optionally, as Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown, the rotating rod 140 has a hook body 141 , and the hook body 141 can be connected to or separated from the hook seat 121 .

[0089] In this embodiment, the structure of the rotating rod 140 is defined. The rotating rod 140 has a hook body 141 at one end thereof, which is used to connect to the hook seat 121. The hook body 141 can cooperate with the hook seat 121 to lock the door 120 to the box 110 or unlock the door 120 from the box 110. Specifically, the hook body 141 can be connected to and separated from the hook seat 121. When the hook body 141 is connected to the hook seat 121, the door 120 closes the box 110 and locks to the box 110. When the hook body 141 is separated from the hook seat 121, the door 120 is unlocked from the box 110, and the door 120 can be pushed to open the box 110. After the driving component 132 receives the door opening instruction, the driving component 132 pushes the rotating rod 140 to rotate in the first direction. During the rotation of the rotating rod 140 in the first direction, the hook body 141 is separated from the hook seat 121, and the door body 120 and the box body 110 are unlocked.

[0090] By providing a hook body 141 at one end of the rotating rod 140 , the door body 120 can be locked or unlocked through the cooperation between the hook body 141 and the hook seat 121 .

[0091] In some embodiments, optionally, as Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the door lock device 130 also includes: a first elastic member 135, which is installed on the bracket 131, and one end of the first elastic member 135 is against the rotating rod 140. When the door body 120 closes the box body 110, the first elastic member 135 is in a compressed state, and the first elastic member 135 applies a thrust to the rotating rod to keep the hook body 141 connected to the hook seat 121.

[0092] In this embodiment, the structure of the door lock device 130 is further defined. The door lock device 130 also includes a first elastic member 135, which is used to provide a pre-tightening force for the hook body 141 so that the hook body 141 is firmly connected to the hook seat 121. Specifically, the first elastic member 135 is mounted on the bracket 131, the driving assembly 132 contacts the upper surface of the end of the rotating rod 140 away from the hook body 141, and the first elastic member 135 contacts the lower surface of the end of the rotating rod 140 away from the hook body 141. When the door is opened, the driving assembly 132 pushes the rotating rod to rotate in the first direction to separate the hook body 141 from the hook seat 121. When the door body 120 closes the box body 110, the first elastic member 135 applies a thrust to the rotating rod 140. Under the thrust of the first elastic member 135, the rotating rod 140 has a tendency to rotate in the second direction, which is opposite to the first direction. Since the hook body 141 is connected to the hook seat 121 in the door closed state and the hook body 141 cannot rotate in the second direction, the first elastic member 135 provides a pre-tightening force for the hook body 141 , and the hook body 141 is firmly connected to the hook seat 121 under the action of the pre-tightening force.

[0093] By providing a first elastic member 135 in the door lock device 130 to resist the rotating rod, the hook body 141 can generate a pre-tightening force on the hook seat 121 under the thrust of the first elastic member 135 on the rotating rod 140, so that the door hook is firmly connected to the hook seat 121.

[0094] In some embodiments, optionally, as Figure 6 As shown, the bracket 131 has a mounting frame 136 , and the mounting frame 136 is used to mount the first elastic member 135 . The rotating rod 140 has a positioning member 142 , and one end of the first elastic member 135 is mounted on the positioning member 142 .

[0095] In this embodiment, the structure of the door lock device 130 is further defined. Door lock device 130 includes a structure for mounting and positioning a first elastic member 135. Specifically, bracket 131 includes a mounting bracket 136, to which the first elastic member 135 is mounted. Mounting bracket 136 can be cylindrical or a plate protruding from bracket 131. A positioning member 142 is provided on the rotating rod 140. The end of the first elastic member 135 that abuts the rotating rod 140 is mounted on positioning member 142, thereby ensuring the installation and positioning of the first elastic member 135.

[0096] In a possible embodiment, the first elastic member 135 is a spring, the positioning member 142 is a columnar structure, and the positioning member 142 is inserted into the first elastic member 135 .

[0097] By arranging the mounting bracket 136 on the bracket 131 and the positioning member 142 on the rotating rod 140 , the first elastic member 135 can be installed and positioned by the mounting bracket 136 and the positioning member 142 , thereby improving the stability of the first elastic member 135 .

[0098] In some embodiments, optionally, as Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the cooking appliance 100 further includes: a cooking assembly, mounted on the housing 110, for heating food; a monitoring circuit, electrically connected to the cooking assembly, wherein when the monitoring circuit is disconnected, the cooking assembly can be powered on, and when the monitoring circuit is on, the cooking assembly is short-circuited; the door lock device 130 further includes: a first switch 150, mounted on the bracket 131, the first switch 150 is used to control the monitoring circuit to be turned on or off; a second switch 160, mounted on the bracket 131, the second switch 160 is used to control the cooking assembly to be powered on or off; wherein, when the door 120 closes the housing 110, the driving assembly 132 maintains the first switch 150 on. 50 is in the trigger state to disconnect the monitoring circuit, and the push rod 170 maintains the trigger state of the second switch 160 to enable the cooking component to be powered on; after the door lock device 130 receives the door opening command, the driving component 132 pushes the rotating rod 140 to rotate in the first direction to the first position and the second position in sequence, and when the rotating rod 140 is in the first position, the driving component 132 is separated from the first switch 150 to enable the monitoring circuit to be turned on, and when the rotating rod 140 is in the second position, the hook body 141 is separated from the hook seat 121, and then as the push rod 170 extends in the direction toward the door body 120, the push rod 170 is separated from the second switch 160, and the cooking component is powered off.

[0099] In this embodiment, the structure of the door lock device 130 is further defined. The cooking appliance 100 includes a cooking assembly and a monitoring circuit. The cooking assembly is used to cook food, and the monitoring circuit is used to control the power supply status of the cooking assembly. Specifically, the cooking assembly is mounted on the housing 110. When the cooking assembly is in operation, it heats and cooks food within the housing 110. The monitoring circuit is electrically connected to the cooking assembly. When the monitoring circuit is disconnected, the cooking assembly can receive power and operate. When the monitoring circuit is connected, the cooking assembly is short-circuited and cannot operate.

[0100] Furthermore, the door lock device 130 also includes a first switch 150 and a second switch 160, which are respectively used to control the on / off state of the monitoring circuit and the power supply status of the cooking component. Specifically, the first switch 150 is mounted on the bracket 131 and is a normally closed microswitch. When the first switch 150 is triggered, the monitoring circuit is disconnected, allowing the cooking component to receive power. When the first switch 150 is not triggered, the monitoring circuit is connected, short-circuiting the cooking component, and preventing it from receiving power. The second switch 160 is mounted on the bracket 131 and is a normally open microswitch. When the second switch 160 is triggered, the cooking component can receive power and can operate normally to heat food. When the second switch 160 is not triggered, the cooking component is powered off and stops operating.

[0101] Furthermore, the first switch 150 is triggered by the drive assembly 132, and the second switch 160 is triggered by the push rod 170. When the door 120 closes the cabinet 110, the drive assembly 132 maintains the triggering state of the first switch 150, thereby keeping the monitoring circuit in the off state. This allows the cooking component to remain powered and operate normally under user control. At the same time, the push rod 170 maintains the triggering state of the second switch 160, thereby keeping the cooking component powered and operating normally.

[0102] Furthermore, after the door lock device 130 receives the door opening command, the drive assembly 132 pushes the rotating rod 140 to rotate in a first direction to a first position and a second position, respectively. When the rotating rod 140 is in the first position, the drive assembly 132 disengages from the first switch 150. At this time, the first switch 150 is not triggered, the monitoring circuit is connected, and the cooking assembly is short-circuited. The rotating rod then rotates to the second position, at which point the hook 141 disengages from the hook seat 121, and the door 120 and the housing 110 are unlocked. In other words, the cooking assembly has already stopped operating before the door 120 and the housing 110 are unlocked. Understandably, if the cooking assembly remains in operation when the door 120 opens the housing 110, microwaves within the housing 110 may leak or high-temperature steam within the housing 110 may overflow, potentially causing burns to the user. Therefore, the cooking appliance 100 proposed in the present application stops the operation of the cooking component before the door 120 and the cabinet 110 are unlocked, thereby improving the safety of the cooking appliance 100.

[0103] Furthermore, after the door 120 and the cabinet 110 are unlocked, the push rod 170 extends toward the door 120. As the push rod 170 extends toward the door 120, the push rod 170 separates from the second switch 160, and the second switch 160 is not triggered. At this time, the cooking component is powered off, ensuring that the cooking component stops operating. As the push rod 170 extends toward the door 120, it pushes the door 120 to open the cabinet 110, creating a gap between the cabinet 110 and the door 120. Since the cooking component is now ensured to be stopped, microwaves or high-temperature steam in the cabinet 110 are prevented from escaping and causing harm to the user, further improving the safety of the cooking appliance 100.

[0104] In some embodiments, optionally, as Figure 5 and Figure 6 As shown, the door lock device 130 also includes: a spring piece 152, which is installed on the first switch member 150, and the first switch member 150 has a first trigger point 151. When the door body 120 closes the box body 110, the driving component 132 pushes the spring piece 152 to squeeze the first trigger point 151. When the driving component 132 pushes the rotating rod 140 to rotate to the first position, the driving component 132 separates from the spring piece 152, and the spring piece 152 separates from the first trigger point 151.

[0105] In this embodiment, the structure of the door lock device 130 is further defined. The door lock device 130 also includes a spring 152, through which the drive assembly 132 can trigger the first switch member 150. Specifically, the first switch member 150 has a first trigger point 151. When the first trigger point 151 is squeezed, the first switch member 150 is triggered; when the first trigger point 151 is not squeezed, the first switch member 150 is not triggered. The spring 152 is mounted on the first switch member 150 and is disposed adjacent to the first switch member 150. When the spring 152 is not squeezed by an external force, a gap exists between the spring 152 and the first trigger point 151, and the first trigger point 151 is not squeezed. When the door body 120 closes the box body 110, the driving component 132 contacts the spring 152 and applies an extrusion force to the spring 152. Under the action of the driving component 132, the spring 152 moves toward the first trigger point 151 and squeezes the first trigger point 151. The first switch 150 is triggered, the monitoring circuit is disconnected, and the cooking component is not short-circuited, so that the cooking component can start normally.

[0106] Furthermore, after the driving component 132 receives the door opening command, when the driving component 132 pushes the rotating rod 140 to rotate to the first position, the driving component 132 is separated from the spring 152, and the spring 152 is no longer squeezed by the driving component 132. The spring 152 returns to a natural state without force. At this time, the spring 152 is separated from the first trigger point 151, the first switch 150 is not triggered, the monitoring circuit is turned on, the cooking component is short-circuited, and the cooking component cannot operate.

[0107] By setting a spring piece 152 in the door lock device 130, the driving component 132 can trigger the first switch component 150 by applying an extrusion force to the spring piece 152, and the driving component 132 can be separated from the spring piece 152 to prevent the first switch component 150 from being triggered, thereby enabling the cooking component to be short-circuited or connected to electricity according to the state of the door body 120 switch.

[0108] In some embodiments, optionally, as Figure 5 and Figure 6 As shown, the push rod 170 includes: an extrusion section 171; an avoidance section 172, connected to the extrusion section 171, and the diameter of the avoidance section 172 is smaller than the diameter of the extrusion section 171; wherein, the second switch member 160 has a second trigger point 161, when the door body 120 closes the box body 110, the extrusion section 171 squeezes the second trigger point 161, and when the door body 120 opens the box body 110, the avoidance section 172 moves to the position of the second trigger point 161, and the avoidance section 172 avoids the second trigger point 161.

[0109] In this embodiment, the structure of push rod 170 is defined. Push rod 170 has a multi-section, variable-diameter structure, including a pressing section 171 and an evasion section 172. The pressing section 171 is used to trigger the second switch 160, while the evasion section 172 is used to restore the second switch 160 to an untriggered state. The diameter of the pressing section 171 is larger than the diameter of the evasion section 172. Specifically, the second switch 160 has a second trigger point 161. When the second trigger point 161 is pressed, the second switch 160 is triggered; when the second trigger point 161 is not pressed, the second switch 160 is not triggered. When the door 120 closes the cabinet 110, the pressing section 171 moves to the position of the second trigger point 161. Due to its larger diameter, the pressing section 171 can compress the second trigger point 161, triggering the second switch 160 and enabling the cooking assembly to be powered on. When the door body 120 opens the box body 110, as the push rod 170 moves toward the door body 120, the avoidance section 172 moves to the position of the second trigger point 161. Since the diameter of the avoidance section 172 is smaller than the diameter of the extrusion section 171, the avoidance section 172 cannot contact the second trigger point 161, the second trigger point 161 is not squeezed, the second switch member 160 is not triggered, and the cooking component is powered off.

[0110] By setting the push rod 170 to a multi-section structure with different diameters, the second switch member 160 can be triggered and non-triggered when the push rod 170 moves, without setting other complex structures, thereby reducing the production cost of the door lock device 130.

[0111] In some embodiments, optionally, the cooking assembly includes at least one of a heating element, a steam generating device, and a microwave generating device.

[0112] In this embodiment, the cooking assembly is defined as comprising at least one of a heating element, a steam generator, or a microwave generator. For example, when the cooking appliance 100 is a microwave oven, the cooking assembly comprises a microwave generator; when the cooking appliance 100 is a combination steamer or oven, the cooking assembly comprises both a heating element and a steam generator.

[0113] In some embodiments, optionally, as Figure 6 As shown, the driving assembly 132 includes: a motor 133, installed on the bracket 131; a driving member 134, installed on the bracket 131, the motor 133 and the driving member 134 are respectively located on both sides of the bracket 131, and the motor 133 drives the driving member 134 to rotate; wherein, the rotating rod 140 has a first mating surface 143, and the driving member 134 can contact the first mating surface 143.

[0114] In this embodiment, the structure of the driving assembly 132 is defined. The driving assembly 132 includes a motor 133 and a driving piece 134, both of which are mounted on the bracket 131, the motor 133 is connected with the driving piece 134, and when the motor 133 operates, the driving piece 134 can rotate under the driving of the motor 133. The driving piece 134 can be a cam. The motor 133 and the driving piece 134 are respectively mounted on both sides of the bracket 131, wherein the driving piece 134 is located on the same side of the bracket 131 as the rotating rod 140, the first switch piece 150, the second switch piece 160 and the push rod 170, and the motor 133 is located on the other side of the bracket 131, so as to avoid interference between the motor 133 and other components in the door lock device 130.

[0115] Further, the rotating rod 140 has a first matching surface 143 for matching the driving piece 134, and the driving piece 134 can contact the first matching surface 143 to push the rotating rod 140 to rotate. Specifically, after the motor 133 receives an opening instruction, the motor 133 starts to operate, and the motor 133 drives the driving piece 134 to rotate. The driving piece 134 can be a cam, and the protruding side of the driving piece 134 rotates to the position where the first matching surface 143 is contacted. As the driving piece 134 continues to rotate, the driving piece 134 pushes the rotating rod 140 to rotate in the first direction, so that the hook body 141 is separated from the hook seat 121 on the door body 120, and the door body 120 is unlocked from the box body 110. The first matching surface 143 can be a plane.

[0116] By providing the first matching surface 143 on the rotating rod 140 for matching the driving piece 134, the driving piece 134 can more easily apply a pushing force to the rotating rod 140, so that the rotating rod 140 receives stable force to rotate.

[0117] In some embodiments, optionally, as shown in Figure 6 The door lock device 130 further includes a second elastic piece 173 mounted on the push rod 170. When the door body 120 closes the box body 110, the second elastic piece 173 is compressed, and when the door body 120 is unlocked from the box body 110, the second elastic piece 173 pushes the push rod 170 to move in the direction towards the door body 120.

[0118] In this embodiment, the structure of the door lock device 130 is further defined. The door lock device 130 also includes a second elastic member 173, which is used to push the push rod 170 to move. Specifically, the second elastic member 173 is mounted on the push rod 170. The push rod 170 has a boss structure, and the bracket 131 has a table surface for limiting position. The two ends of the second elastic member 173 respectively abut against the table surface on the bracket 131 and the boss on the push rod 170. When the door body 120 closes the box body 110, the push rod 170 is squeezed by the door body 120, and the door body 120 pushes the push rod 170 to move in the direction toward the interior of the box body 110. The second elastic member 173 is compressed, and the second elastic member 173 exerts a thrust on the push rod 170 in the direction toward the door body 120. When the door 120 is unlocked from the box 110, the second elastic member 173 pushes the push rod 170 to move toward the door 120, so that the push rod 170 can push the door 120 to open the box 110, thereby realizing automatic door opening.

[0119] By providing the second elastic member 173 in the door lock device 130 , the push rod 170 can be pushed by the second elastic member 173 to move, thereby realizing automatic door opening.

[0120] In some embodiments, optionally, as Figure 6 and Figure 7 As shown, when the hook body 141 is connected to the hook seat 121, the rotating rod 140 is located in the third position, and the door lock device 130 also includes: a limit member 137, which is connected to the bracket 131, and the rotating rod 140 has a second mating surface 144. When the rotating rod 140 is in the third position, the limit member 137 cooperates with the second mating surface 144 to prevent the rotating rod 140 from rotating in the second direction, which is opposite to the first direction.

[0121] In this embodiment, the door lock device 130 is further defined. The door lock device 130 also includes a stopper 137. The rotating rod 140 has a second mating surface 144 that mates with the stopper 137. The mating of the stopper 137 and the second mating surface 144 enables the rotating rod 140 to be stopped and limited. Specifically, when the hook body 141 is connected to the hook seat 121, the door body 120 and the housing 110 are locked, and the rotating rod 140 is in the third position. When the rotating rod 140 is in the third position, the stopper 137 abuts the second mating surface 144. The second mating surface 144 is a plane, and the stopper 137 has a certain width. Under the action of the stopper 137, the second mating surface 144 cannot rotate in a second direction opposite to the first direction, thereby maintaining the rotating rod 140 in the third position.

[0122] In some embodiments, optionally, after the door body 120 is unlocked from the box body 110 and the box body 110 is opened, the rotating rod 140 can be restored to the third position. In the process of the door body 120 closing the box body 110, the hook body 141 first contacts the hook seat 121 and moves along the surface of the hook seat 121 until the door body 120 closes the box body 110, the hook body 141 is connected to the hook seat 121, and the rotating rod 140 rotates to the third position again.

[0123] In this embodiment, the door closing process is defined. During the process of the door 120 opening the housing 110, the rotating rod 140 needs to deviate from the third position to separate the hook 141 from the hook seat 121, thereby unlocking the door 120 from the housing 110. After the door 120 is unlocked from the housing 110 and the door 120 opens the housing 110, the rotating rod 140 can return to the third position. When the user needs to close the door, the user pushes the door 120 toward the housing 110. During the door closing process, the hook 141 first contacts the hook seat 121 on the door 120. As the door 120 rotates toward the housing 110, the hook 141 moves along the surface of the hook seat 121 until the door 120 closes the housing 110. The hook 141 connects with the hook seat 121, locking the door 120 to the housing 110. At this point, the rotating rod 140 rotates to the third position again. In this way, the door body 120 and the box body 110 can be automatically locked when the door is closed.

[0124] In some embodiments, optionally, as Figure 7 、 Figure 8 and Figure 9 As shown, the hook seat 121 has a guide slope 122 on the side facing the box body 110 , and the hook body 141 has a curved surface 145 on the side facing the door body 120 .

[0125] In this embodiment, the structures of the hook seat 121 and the hook body 141 are defined. The hook seat 121 has an arcuate surface 145 on the side facing the box body 110, and the hook seat 121 has a guide slope 122 on the side facing the box body 110. When the door body 120 closes the box body 110, the arcuate surface 145 of the hook body 141 moves along the guide slope 122 of the hook seat 121 until the hook body 141 is connected and locked with the hook seat 121. Specifically, when the door body 120 closes the box body 110, the door body 120 rotates toward the box body 110, and the arc surface 145 on the hook body 141 first contacts the guide slope 122 on the hook seat 121. As the door body 120 continues to rotate toward the box body 110, the arc surface 145 on the hook body 141 slides upward along the guide slope 122 until the door body 120 is closed in place, the arc surface 145 separates from the guide slope 122, and the hook body 141 is locked to the hook seat 121.

[0126] The guide bevel 122 has a guiding function, and the arc surface 145 also has the function of reducing friction. By setting the arc surface 145 at the end of the hook body 141 and setting the guide bevel 122 on the side of the hook seat 121 facing the box body 110, the friction between the hook body 141 and the hook seat 121 can be reduced through the cooperation of the guide bevel 122 and the arc surface 145, so that the hook body 141 and the hook seat 121 can be connected more smoothly, reducing the user's resistance to closing the door.

[0127] In some embodiments, optionally, as Figure 7 As shown, the hook body 141 further has an extrusion slope 146 , which is located on the side of the arc surface 145 away from the door body 120 . When the door body 120 closes the box body 110 , an angle is formed between the extrusion slope 146 and the guide slope 122 .

[0128] In this embodiment, the structure of the hook body 141 is further defined. The hook body 141 also has an extrusion bevel 146, which is located on the side of the arc surface 145 facing away from the door body 120. The angle between the extrusion bevel 146 and the horizontal plane ranges from 55° to 70°. The guide bevel 122 on the hook seat 121 forms an angle with the horizontal plane, and the angle between the guide bevel 122 and the horizontal plane ranges from 20° to 35°. When the door body 120 closes the box body 110, the extrusion bevel 146 and the guide bevel 122 form an angle, and the angle range is 75° to 105°. This allows the rotating rod 140 to provide an extrusion force on the door body 120 toward the interior of the box body 110, and the extrusion force ranges from 35N to 60N.

[0129] In some embodiments, optionally, as Figure 7 As shown, the rotating rod 140 further has an avoidance groove 147 . The avoidance groove 147 is arranged adjacent to the hook body 141 , and the avoidance groove 147 is used to avoid the hook seat 121 .

[0130] In this embodiment, the structure of rotating lever 140 is further defined. Rotating lever 140 also has an escape groove 147, located adjacent to hook body 141 and on the side of hook body 141 facing away from door body 120. This allows hook body 141 to form a hook-shaped structure. When hook body 141 is connected to hook seat 121, the protruding structure of hook seat 121 allows this protrusion to penetrate into escape groove 147, allowing escape groove 147 to clear hook seat 121. This allows hook body 141 to lock tightly to hook seat 121, securing the connection between the two.

[0131] In some embodiments, optionally, as Figure 1 、 Figure 2 、 Figure 10 and Figure 11As shown, the cooking appliance 100 also includes: at least two hinge devices 180, respectively installed on both sides of the door body 120, the hinge devices 180 are used to rotatably connect the door body 120 to the box body 110, and at least one of the at least two hinge devices 180 has a damping assembly 181; after the push rod 170 pushes the door body 120 to the first open position, the door body 120 can continue to rotate under the action of gravity, and when the door body 120 rotates to the second open position, the damping assembly 181 generates rotational resistance to the door body 120.

[0132] In this embodiment, the structure of the cooking appliance 100 is further defined. The cooking appliance 100 also includes at least two hinge devices 180, through which the door 120 is rotatably connected to the door body 120, and the hinge devices 180 can also realize the further automatic opening of the door body 120. Specifically, the at least two hinge devices 180 are respectively installed on both sides of the door body 120 to ensure that the overall force of the door body 120 is balanced. At least one of the at least two hinge devices 180 has a damping assembly 181. When the door body 120 further opens the box body 110, the damping assembly 181 can generate resistance to the door body 120, thereby slowing the rotation speed of the door body 120.

[0133] Specifically, during the automatic door opening process of the cooking appliance 100, when the door body 120 rotates to the first position, the push rod 170 no longer extends. At this time, the door body 120 can continue to rotate away from the housing 110 under the action of its own gravity, and the opening angle of the door body 120 continues to increase until the door body 120 rotates to the second open position. In one possible embodiment, when the door body 120 is in the second open position, the angle between the door body 120 and the housing 110 is 45° to 55°. Furthermore, when the door body 120 rotates to the second position, the damping assembly 181 generates rotational resistance on the door body 120. The door body 120 continues to rotate under the action of gravity to open the housing 110. However, due to the action of the damping assembly 181 on the door body 120, the door body 120 rotates slower under the action of the rotational resistance, thereby achieving a slow door opening effect.

[0134] In one possible embodiment, there are two hinge devices 180, each mounted on either side of the door body 120. One of the hinge devices 180 has a damping assembly 181, while the other does not. This can reduce the production cost of the cooking appliance 100 while achieving a slow-opening door.

[0135] By providing the cooking appliance 100 with a hinge device 180 having a damping assembly 181, the damping assembly 181 can slow down the opening speed of the door 120, achieving a slow-opening technical effect and improving the user experience. Furthermore, the push rod 170 pushes the door 120 to rotate when the door 120 and the housing 110 are already unlocked, eliminating the risk of deformation of the door 120 or cracking of the glass on the door 120.

[0136] In some embodiments, optionally, as Figure 1 and Figure 2 As shown, the cooking appliance 100 further includes a control panel 190 installed on the housing 110 , and the control panel 190 is electrically connected to the driving assembly 132 .

[0137] In this embodiment, the structure of the cooking appliance 100 is further defined. The cooking appliance 100 also includes a control panel 190 for controlling the operation of the cooking appliance 100. Specifically, the control panel 190 is mounted on the housing 110 and is exposed from the housing 110. The control panel 190 and the door 120 are located on the same side, allowing the user to input control commands through the control panel 190. The control panel 190 is electrically connected to the drive assembly 132. When the door 120 needs to be opened, the user inputs a door opening command through the control panel 190. Upon receiving the door opening command, the drive assembly 132 begins to operate, pushing the rotating rod 140 in a first direction until the hook 141 separates from the hook seat 121, thereby unlocking the door 120 from the housing 110. The push rod 170 then automatically moves toward the door 120, pushing the door 120 to open the housing 110, achieving automatic door opening.

[0138] By providing the control panel 190 in the cooking appliance 100 , the user can control the cooking appliance 100 through the control panel 190 , thereby improving the user's convenience.

[0139] In some embodiments, the cooking appliance 100 optionally includes an oven, a microwave oven, or a steam oven.

[0140] In one possible embodiment, the present invention provides an oven (i.e., cooking appliance 100) and an automatic door opening mechanism (i.e., door lock device 130) thereof, which enables the oven to be electrically unlocked and the oven door (i.e., door body 120) to open automatically. The oven (i.e., cooking appliance 100) of the present application is composed of an oven body (i.e., oven housing 110), a control panel 190, an automatic door locking mechanism (i.e., door lock device 130), a hinge (i.e., hinge device 180), an oven door (i.e., door body 120), and a hook seat 121 on the oven door. Figure 1 and Figure 2The figure shows the oven proposed in this application. The oven proposed in this application can open and close the door automatically, and no handle is required on the door, giving the front of the oven a strong sense of unity and seamless integration into the cabinet. The control panel 190 includes an integrated door opening control button. When the user needs to open the oven door, they simply touch the door opening button to initiate the door opening command.

[0141] The automatic door locking mechanism (ie, door locking device 130) is generally installed on the side of the oven body (ie, box body 110), and the automatic door locking mechanism cooperates with the hook seat 121 installed on the oven door to keep the oven door in the required closed state.

[0142] Specifically, the coordination status between the automatic door locking mechanism and the furnace door, such as Figure 3 As shown, in the closed state, the front end of the automatic door locking mechanism hooks the hook seat 121 on the oven door, so that the oven door remains in the closed state under an appropriate inward locking force F (about 35N to 60N). The oven door has a good sealing state, avoiding air leakage and microwave leakage in the oven.

[0143] Figure 4 The oven is shown with the automatic door locking mechanism engaged. The door is manually pushed inward by the user to close. When fully closed, the lever (i.e., rotating rod 140) and hook seat 121 on the door engage and lock, compressing hook seat 121 and providing an inward locking force F on the door.

[0144] Among them, the partial enlarged diagram of the automatic door locking mechanism and the furnace door in the closed state is as follows Figure 5 As shown in the figure, when the user manually closes the oven door, after the oven door rotates a certain angle, the hook seat 121 on the oven door first contacts the lever hook head (i.e., hook body 141) of the automatic door locking mechanism. The inclined surface of the hook seat 121 (i.e., guide inclined surface 122) pushes the lever (i.e., rotating rod 140) upward, causing the lever hook head (i.e., hook body 141) to pass the highest point of the hook seat 121. When the oven door is fully closed, the lever (i.e., rotating rod 140), under the action of the rear-end thrust, presses the hook seat 121 downward, providing the appropriate inward locking force F for the oven door.

[0145] The door opening status of an oven with an automatic door locking mechanism is as follows: Figure 2 As shown. After the automatic door locking mechanism (i.e., the door locking device 130) receives the door opening command, the motor 133 is started, and the motor 133 drives the cam at the end (i.e., the driving member 134) to rotate. The cam then squeezes the tail of the lever (i.e., the rotating rod 140) downward, causing the hook head at the front end of the lever (i.e., the hook body 141) to tilt upward, so that the hook head is separated from the hook seat 121 and no longer applies inward pressure to the furnace door. The furnace door rotates outward under the combined action of gravity and the slow-opening hinge (i.e., the hinge device 180 with the damping component 181) until the furnace door opens to a maximum angle of approximately 90°. During this process, the slow-opening hinge cushions the furnace door to prevent it from opening too quickly.

[0146] The structure of the automatic door lock mechanism is as follows Figure 6 As shown, it is composed of a bracket 131, a motor 133, a cam (i.e., a driving member 134), a micro switch 1 (i.e., a first switch member 150), a micro switch 2 (i.e., a second switch member 160), a push rod 170, and a lever (i.e., a rotating rod 140), wherein each component is mounted on the bracket 131.

[0147] Motor 133 is mounted on the back of bracket 131 and passes through it. A cam (i.e., driver 134) is mounted on the front end of the motor's shaft. Motor 133 rotates the cam clockwise. When the door is closed, the cam triggers the microswitch (normally closed), disconnecting the monitoring circuit. This prevents the heating element and steam or microwave generator circuits (i.e., the cooking components) from shorting out, allowing normal operation.

[0148] After receiving the door opening command, the motor 133 starts to drive the cam (i.e., the driving member 134) to rotate clockwise. After rotating to a certain angle, the micro switch 1 (i.e., the first switch member 150) is no longer triggered, the monitoring circuit is turned on, and the heating tube, steam or microwave generating circuit (i.e., the cooking component) is short-circuited and cannot work normally. As the cam continues to rotate, the front end of the cam begins to press downward on the inclined surface (i.e., the first mating surface 143) at the tail of the lever (i.e., the rotating rod 140). The structure of the lever (i.e., the rotating rod 140) is as follows: Figure 7 As shown, the cam overcomes the thrust of the compression spring (i.e., first elastic member 135), causing the lever to rotate downward (i.e., in the first direction). After a certain angle, the lever reaches its maximum angle, and the front hook head (i.e., hook body 141) rises and completely disengages from the hook seat 121 on the oven door. The oven door then automatically opens under the force of gravity and the outward force of the slow-opening hinge (i.e., hinge device 180 with damping assembly 181).

[0149] The front end of the push rod 170 of the automatic door locking mechanism (i.e., door lock device 130) protrudes from the oven body (i.e., housing 110). When the oven door (i.e., door body 120) is closed, the oven door drives the push rod 170 inward (i.e., toward the interior of housing 110), while the push rod 170 presses the second microswitch (normally open). When the oven door is fully closed, the push rod 170 maintains the triggering of the second microswitch (i.e., second switch element 160), energizing the heating tube and the steam or microwave generating circuit (i.e., the cooking component), allowing normal operation. When the oven door is opened, the lever (i.e., rotating rod 140) is pushed downward by the cam (i.e., driving element 134), causing the lever hook (i.e., hook body 141) to clear the hook seat 121. The push rod 170 then returns to its original position, disconnecting the heating tube and the steam or microwave generating circuit (i.e., the cooking component). At the same time, a thrust of about 5N to 10N is provided to the furnace door, which can rotate the furnace door outward by about 0.5° to 5°, and then open freely under the action of the gravity of the furnace door and the slow-opening hinge (i.e., the hinge device 180 with the damping component 181).

[0150] The lever structure (i.e., rotating rod 140) forms a mating relationship with the hook seat 121 of the furnace door. To ensure smooth manual door closing, the hook head (i.e., hook body 141) at the front end of the lever is an arc-shaped surface, which can smoothly pass over the inclined surface (i.e., guide inclined surface 122) of the hook seat 121. The inclined surface at the rear of the hook head (i.e., extrusion inclined surface 146) (at an angle of approximately 55° to 70° with the horizontal plane) presses against the inclined surface of the furnace door hook seat 121 (at an angle of approximately 20° to 35° with the horizontal plane), forming an angle of approximately 75° to 105°. When the lever is in the closed position, it maintains an inward extrusion force of approximately 35N to 60N on the furnace door.

[0151] The clearance groove (i.e., the clearance groove 147) at the rear of the hook head is used to avoid interference with the inclined surface (i.e., the guide inclined surface 122) of the hook seat 121. The second mating surface 144 of the lever engages with the limit pin (i.e., the limit member 137) on the bracket 131 to limit the upward rotation of the lever tail (i.e., limit the rotation of the rotation rod 140 in the second direction).

[0152] The spring seat (i.e., positioning member 142) at the rear end of the lever (i.e., rotating rod 140) serves as a mounting seat for the compression spring (i.e., first elastic member 135). The compression spring is compressed, maintaining an upward push on the lever. The inclined surface (i.e., first mating surface 143) at the rear end of the lever acts as a cam (i.e., driving member 134). As the cam rotates with the motor 133, the cam presses against the inclined surface, allowing the lever to overcome the spring force and rotate downward (i.e., in the first direction), thereby allowing the lever hook (i.e., hook body 141) to clear the hook seat 121 on the oven door.

[0153] The hook seat 121 structure and installation on the furnace door are as follows Figure 8 and Figure 9 As shown, the hook seat 121 is embedded in the surface of the furnace door. The front end of the furnace door has an opening to allow the lever hook of the automatic door locking mechanism to move freely in and out. The hook seat 121 has an inclined surface (i.e., guide inclined surface 122) with an angle of approximately 20° to 35°, which allows the lever hook to slide smoothly. The top of the inclined surface is provided with an arc surface (i.e., arc surface 145) for squeezing the rear inclined surface of the lever hook, ensuring a moderate inward pressure when the furnace door is closed.

[0154] When the oven door is opened at an angle of 45° to 55°, the oven door opens faster, and the slow-opening hinge assembly (i.e., the hinge device 180 with the damping assembly 181) is used for buffering and slowing down the opening speed of the oven door. Figure 10The illustrated embodiment shows a vertical hinge mounted on the oven door. The hinge assembly (i.e., hinge device 180) can also be a horizontal hinge mounted on the side of the oven cavity. The slow-opening hinge assembly consists of a hinge (i.e., hinge device 180) with a damper (i.e., damping assembly 181) on one side and a hinge without a damper on the other side. This allows for slow-opening of the oven door at a wide angle while avoiding the high cost of using multiple dampers.

[0155] The various states of the slow-opening hinge when the furnace door is open are as follows: Figure 12 、 Figure 13 and Figure 14 As shown in Figure 2. The opening angles of the furnace door are θ1, θ2 and θ3, respectively, where θ1<θ2<θ3. Figure 12 As shown, when the furnace door is opened at an angle θ1 of about 0° to 5°, the slow-opening hinge and the gravity G of the furnace door provide a small outward force F1 for the furnace door, and the force F1 is about 5N to 10N. Figure 13 As shown, the furnace door opening angle increases to θ2, and then the slow-opening hinge quickly opens the furnace door under the action of the horizontal component F2 of the furnace door gravity G. θ2 is about 45° to 55°. At this time, the buffer of the slow-opening hinge (i.e., the damping component 181) starts to buffer the furnace door to prevent the furnace door from opening too quickly. Figure 14 As shown, the furnace door opens at an angle of θ3, and the slow-opening hinge continues to open under the action of the outward horizontal force F3 of the furnace door's gravity G. When the furnace door is opened to its maximum angle of approximately 88°, the slow-opening hinge's buffer prevents the furnace door from oscillating beyond approximately 3°.

[0156] The oven provided by the present application has a simple and effective automatic door locking mechanism, which enables the oven to have an automatic door opening function. First, a motor 133 is used to drive the cam, and the cam pushes the lever to rotate downward to control the automatic opening of the lever door hook. Compared with the original complex transmission system and large thrust, the new product has a simple structure and low cost. Second, the motor 133 rotates quickly, and the cam can make the lever rotate a large angle and disengage from the hook seat 121 at a small angle. The reaction time is fast, and the door opening process is quick compared to the original product. Third, the lever automatically disengages from the hook seat 121, and is only subjected to a small thrust (about 5N to 10N) from the push rod 170. When the oven door is opened, it is in a free outward moving state. Compared with the original product, there is no risk of oven door deformation or door glass bursting.
