Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household electrical appliances, in particular to a cooking box body and a cooking appliance. BACKGROUND

[0002] The microwave oven in the prior art is used for opening the door body only by one-step operation. In the case that there are children in the home, the door body is opened by mistake by the children, which causes the children to be scalded by high temperature in the microwave oven if the microwave oven is in the working state, and the safety of the microwave oven is poor. SUMMARY

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

[0004] To this end, the first object of the present application is to provide a cooking box body.

[0005] The second object of the present application is to provide a cooking appliance.

[0006] To achieve the above at least one object, according to the first aspect of the present application, a cooking box body is provided, comprising: a main body; a door body assembly movably connected with the main body, the door body assembly being movable between an open position and a closed position; a locking catch portion provided on the main body; a locking hook portion provided on the door body assembly, the locking hook portion being movable relative to the door body assembly between a first position and a second position; in the case that the door body assembly is in the closed position and the locking hook portion is in the first position, at least part of the locking hook portion extends into the main body, and at least part of the locking catch portion protrudes away from the door body assembly to limit the locking hook portion, so as to lock the door body assembly to the main body; in the case that the door body assembly is in the closed position and the locking hook portion is in the second position, the locking hook portion is separated from the locking catch portion, so as to unlock the door body assembly relative to the main body, and the door body assembly is movable to the open position under the action of an external force.

[0007] The cooking box body provided in the present application can be used in a cooking appliance, and the cooking box body comprises a main body and a door body assembly. The door body assembly is movably connected with the main body, and the main body comprises a cooking cavity. The door body is used for opening or closing the cooking cavity. Specifically, the door body assembly is movable between an open position and a closed position. When the door body assembly is in the open position, the door body assembly opens the cooking cavity. When the door body assembly is in the closed position, the door body assembly closes the cooking cavity. The door body assembly can be hinged with the main body through a connecting shaft, so that the door body assembly is rotatably connected relative to the main body. A user can pull the door body assembly to rotate relative to the main body around the connecting shaft within a certain angle range, so as to move the door body assembly between the open position and the closed position.

[0008] Understandably, in the case of a family with children, if the door body assembly can be directly opened (i.e. the door body assembly can be opened by only one step operation), it is easy to cause the children to mistakenly open the door body assembly. In the case of the operation of the cooking appliance, the cooking cavity is in a high temperature state, and if the children mistakenly open the door body assembly due to the mistaken operation, it is easy to cause the high temperature in the cooking cavity to scald the children. In order to avoid the above problems, the present application sets a structure for locking the door body assembly in the cooking box body, so as to lock the door body assembly, so that the user cannot open the door body assembly by only one step operation.

[0009] Specifically, the cooking box body further comprises a lock catch portion and a lock hook portion, the lock catch portion is matched with the lock hook portion to lock the door body assembly. The lock catch portion is arranged on the main body, and the lock hook portion is arranged on the door body assembly. The lock hook portion can move between different positions to realize the locking and unlocking of the door body assembly. The specific structure of the lock catch portion and the lock hook portion is as follows: at least part of the lock catch portion protrudes in the direction away from the door body assembly. In the case that the door body assembly is locked to the main body, at least part of the lock hook portion protrudes into the main body, and the protruding lock catch portion can limit the lock hook portion protruding into the main body. In the case that the door body assembly has a tendency to move in the direction towards the open position, the lock catch portion limits the lock hook portion to prevent the lock hook portion from moving out of the main body. Since the lock hook portion is arranged on the door body assembly, the door body assembly can be locked to the main body by the lock hook portion, thereby realizing the locking of the door body assembly, and further preventing the user from opening the door body assembly by one step operation.

[0010] Further, the cooperation between the lock hook portion and the lock catch portion is further limited. The lock hook portion can move relative to the door body assembly between a first position and a second position to realize the locking and unlocking of the door body assembly. Specifically, when it is necessary to lock the door body assembly, the user can move the lock hook portion to the first position in the case that the door body assembly is located at the closed position. At this time, at least part of the lock hook portion protrudes into the main body, and the lock catch portion arranged on the main body cooperates with the lock hook portion protruding into the main body. The lock catch portion can limit the lock hook portion, and in the case that the door body assembly has a tendency to move in the direction towards the open position, the lock catch portion stops the lock hook portion, and the lock hook portion cannot move out of the main body. Since the lock hook portion is arranged on the door body assembly, if the lock hook portion cannot move out of the main body, the door body assembly cannot be separated from the main body, thereby realizing the technical effect of locking the door body assembly to the main body.

[0011] Further, when it is needed to unlock the door body assembly, the user can move the locking hook part to the second position when the door body assembly is located at the closed position. At this time, the locking hook part and the protruding part of the locking catch part have a certain spacing, the locking hook part is separated from the locking catch part, the locking catch part cannot continue to limit the locking hook part, and the door body assembly has been unlocked relative to the main body. When the locking hook part is located at the second position relative to the door body assembly, the user can exert a force on the door body assembly in the direction of the opening position. Since the locking catch part has already been unable to continue to limit the locking hook part, the door body assembly has been unlocked relative to the main body, so that the door body assembly can be moved relative to the main body under the action of the external force, and the door body assembly can be moved to the opening position. That is, the user needs to use a two-step door opening method when opening the door body assembly. First, the locking hook part is moved to the second position relative to the door body assembly to achieve the unlocking between the door body assembly and the main body. Then, the door body assembly is pulled to move the door body assembly to the opening position, and the door opening step is completed.

[0012] By arranging the locking catch part in the main body and the locking hook part in the door body assembly, the locking of the door body assembly and the main body can be achieved through the cooperation of the locking hook part and the locking catch part. The user can be prevented from opening the door body assembly due to misoperation, and the user can be prevented from being scalded by high temperature in the cooking cavity. Moreover, since the locking hook part can be moved between the first position and the second position relative to the door body assembly, the user needs to move the locking hook part to the second position before opening the door body assembly to unlock the door body assembly relative to the main body, and then the door body can be opened. The two-step door opening method of the door body assembly is achieved, and the safety of the product is improved.

[0013] According to the cooking box body, the following distinguished technical features can be further provided.

[0014] In the above technical solution, further, the locking hook part comprises a locking piece, the locking piece extends out of the door body assembly in the direction towards the main body, and in the case that the door body assembly is located at the closed position and the locking hook part is located at the first position, the locking piece extends into the main body, and the locking catch part limits the locking piece.

[0015] In the technical solution, the structure of the locking hook part is limited. The locking hook part comprises a locking piece, the locking piece extends out of the door body assembly in the direction towards the main body, and the locking piece is used to cooperate with the locking catch part to enable the door body assembly to be locked to the main body. Specifically, in the case that the door body assembly is located at the closed position, the user can move the locking hook part to the first position. At this time, the locking piece extends into the main body, the locking piece cooperates with the locking catch part, and the locking catch part limits the locking piece. When the door body assembly has a tendency to move towards the opening position under the action of the external force, the locking piece is pulled by the door body assembly to move in the direction of moving out of the main body. The locking catch part limits the locking piece to prevent the locking piece from moving, so that the door body assembly can be locked to the main body.

[0016] In one possible technical solution, the locking member comprises a connecting rod and a bent part, the bent part is arranged at one end of the connecting rod facing the main body, when the locking part is located at the first position, the locking member extends into the main body, the bent part is located at the protrusion in the locking part and faces away from the door body assembly, when the door body assembly is pulled by external force and has a tendency to move towards the opening position, the bent part abuts against the protrusion in the locking part to limit the bent part, thereby achieving the technical effect of locking the door body assembly to the main body.

[0017] By arranging the locking member in the locking hook part, the door body assembly can be locked to the main body through the cooperation of the locking member and the locking part.

[0018] In the above technical solution, further, the locking part comprises a limiting member, the limiting member protrudes in a direction away from the door body assembly, and the limiting member is used to limit the locking member.

[0019] In this technical solution, the structure of the locking part is limited. In order to enable the locking part to limit the locking hook part, the application arranges a limiting member capable of cooperating with the locking hook part in the locking part. The limiting member protrudes in a direction away from the door body assembly, when the door body assembly is located at the closed position and the locking hook part is located at the first position, the locking member in the locking hook part extends into the main body, at this time, the bent part in the locking member is located at the side of the limiting member away from the door body assembly. When the door body assembly is pulled by external force and has a tendency to move towards the opening position, the bent part abuts against the limiting member to limit the bent part, thereby limiting the locking hook part. Since the locking hook part is arranged on the door body assembly, the door body assembly cannot move under the cooperation of the locking hook part and the limiting member, thereby achieving the technical effect of locking the door body assembly to the main body.

[0020] By arranging the limiting member protruding in a direction away from the door body assembly in the locking part, the locking hook part can be limited by the limiting member, thereby achieving the technical effect of locking the door body assembly to the main body.

[0021] In the above technical solution, further, the locking part further comprises a first mounting plate arranged in the main body, the main body is provided with a first opening, the first mounting plate is provided with a second opening corresponding to the first opening, and the locking member can extend into the main body through the first opening and the second opening in sequence.

[0022] In this technical solution, the structure of the locking part is further limited. In order to install and fix the limiting member, the application further arranges a first mounting plate in the locking part, and the first mounting plate is used to install the limiting member. Specifically, the main body comprises a front plate arranged towards the door body assembly, the first mounting plate is installed on the front plate, the limiting member is connected to the side of the first mounting plate away from the door body assembly, and the limiting member protrudes from the surface of the first mounting plate.

[0023] Further, in order to enable the first mounting plate to be mounted to the front plate, the application further provides a plurality of mounting holes on the first mounting plate, which are used to connect the first mounting plate to the front plate. Specifically, the mounting holes can be threaded holes, and the first mounting plate can be connected to the front plate by screws, which pass through the mounting holes to connect the first mounting plate to the front plate.

[0024] Further, in order to enable the locking member to extend into the main body and cooperate with the limiting member, the application provides a first opening in the main body, which is arranged on the front plate, and a second opening on the first mounting plate corresponding to the first opening, and the locking member can extend into the main body through the first opening and the second opening in sequence. Moreover, the locking member can move within a certain range in the first opening and the second opening, and when the door assembly is in the closed position, the locking member can move in the first opening and the second opening when the locking hook part moves between the first position and the second position.

[0025] Further, the plurality of mounting holes are located on both sides of the second opening, so that the first mounting plate is balanced in force, and the first mounting plate can be stably connected to the main body.

[0026] By providing the first mounting plate in the locking hook part, the limiting member can be installed and fixed by the first mounting plate. By providing the first opening in the main body and the second opening in the first mounting plate corresponding to the first opening, the locking member can smoothly extend into the main body through the first opening and the second opening, and the locking member can normally cooperate with the limiting member to realize the locking function of the door assembly.

[0027] In the above technical solution, further, the cooking box body further comprises: a sliding groove arranged on the door assembly, and at least part of the locking hook part is located in the sliding groove, and the locking hook part can move along the sliding groove between the first position and the second position.

[0028] In the technical solution, the structure of the door body assembly is further limited. In order to enable the hook portion to move relative to the door body assembly between the first position and the second position, the application further provides a sliding groove in the door body assembly, which is used to limit the movement track of the hook portion. At least part of the hook portion is located in the sliding groove, and the hook portion can move along the sliding groove between the first position and the second position. Specifically, the sliding groove can be arranged on the side wall or the top wall of the door body assembly, at least part of the hook portion is located in the sliding groove, and the groove wall of the sliding groove limits the hook portion located in the sliding groove, so that the hook portion can move along the sliding groove under the action of an external force. When the hook portion is located at the first position relative to the door body assembly, the hook portion arranged in the sliding groove is located at the first end of the sliding groove, and during the movement of the hook portion relative to the door body assembly towards the second position, the hook portion arranged in the sliding groove moves away from the first end of the sliding groove. In this way, on the one hand, the movement track of the hook portion can be limited by the sliding groove, and on the other hand, the position of the hook portion can be limited by the inner wall of the sliding groove, so that the hook portion can stop at the first position.

[0029] By arranging the sliding groove in the door body assembly and arranging at least part of the hook portion in the sliding groove, the hook portion can move along the sliding groove between the first position and the second position, so that on the one hand, the movement track of the hook portion can be limited by the sliding groove, and on the other hand, the position of the hook portion can be limited by the inner wall of the sliding groove, so that the hook portion can stop at the first position.

[0030] In the above technical solution, further, the hook portion further comprises a pushing member for driving the locking member to move, the pushing member is located on the side of the sliding groove facing the outside, and the locking member is located on the side of the sliding groove facing away from the outside.

In order to facilitate the user to move the hook portion, the application provides a pushing member in the hook portion, and the user can push the hook portion relative to the door body assembly between the first position and the second position through the pushing member. The pushing member is located on the side of the sliding groove facing the outside, and the locking member is located on the side of the sliding groove facing away from the outside. The pushing member can drive the locking member to move. Specifically, when the user needs to lock the door body assembly to the main body, the user applies a pushing force to the pushing member, the pushing member drives the locking member to move, the locking member inserted into the main body is driven by the pushing member to a position capable of cooperating with the limiting member, and the limiting member can limit the locking member to enable the door body assembly to be locked to the main body. When the user needs to unlock the door body assembly from the main body, the user applies a pushing force in the opposite direction to the pushing member, the pushing member drives the locking member to move in the opposite direction, and the locking member inserted into the main body is driven by the pushing member to a position away from the limiting member, so that the limiting member no longer limits the locking member, so that the door body assembly is unlocked relative to the main body.

[0032] By arranging the pushing piece in the locking hook part, the user can drive the locking piece to move through the pushing piece, so that the locking hook part can move between the first position and the second position relative to the door body assembly, thereby realizing the locking and unlocking of the door body assembly relative to the main body.

The locking hook part further comprises a second mounting plate, the pushing piece and the locking piece are mounted on the second mounting plate, the pushing piece can drive the second mounting plate to move, and the second mounting plate drives the locking piece to move, thereby realizing the technical effect of driving the locking piece to move through the pushing piece. Specifically, the second mounting plate is located on the side of the sliding groove away from the outside, and the second mounting plate can cover the sliding groove to avoid the second mounting plate being stuck in the sliding groove during movement relative to the sliding groove, so that the second mounting plate can smoothly slide relative to the sliding groove, and the second mounting plate can smoothly drive the locking piece to move under the pushing of the pushing piece.

[0035] By arranging the second mounting plate in the locking hook part, on the one hand, the pushing piece and the locking piece can be mounted and fixed, and on the other hand, the second mounting plate can be driven to move through the pushing piece, and the locking piece is driven to move through the second mounting plate, thereby realizing the technical effect of driving the locking piece to move through the pushing piece.

[0036] In the above technical solution, further, the cooking box body further comprises an elastic piece, one end of the elastic piece is connected to the door body assembly, and the other end of the elastic piece is connected to the locking hook part, and in the case that the locking hook part is located at the first position, the elastic piece applies a pulling force to the locking hook part in the direction from the second position to the first position.

[0037] In the technical solution, in order to improve the reliability of the cooperation between the locking hook part and the lock part, the application further arranges an elastic piece in the cooking box body, and applies a pulling force to the locking hook part through the elastic piece, so that the locking hook part can stably stop at the first position. Specifically, one end of the elastic piece is connected to the door body assembly, and the other end of the elastic piece is connected to the locking hook part, and in the case that the locking hook part is located at the first position, the elastic piece is stretched, and the elastic piece applies a pulling force to the locking hook part in the direction from the second position to the first position. The locking hook part has a tendency to continue to move under the action of the pulling force of the elastic piece, but the groove wall of the sliding groove can limit the locking hook part, so that the locking hook part can stably remain at the first position, preventing the locking hook part from loosening, thereby improving the reliability of the cooperation between the locking hook part and the lock part, and enabling the door body assembly to be firmly locked to the main body.

[0038] In one possible technical solution, the second mounting plate is provided with a hook, one end of the elastic member is connected to the door body assembly, and the other end is connected to the hook of the second mounting plate, the elastic member exerts a pulling force on the second mounting plate, the second mounting plate is connected to the pushing member through the connecting member, and the connecting member is located in the sliding groove, the groove wall of the sliding groove limits the connecting member, so that the locking member is stably kept in the first position.

[0039] By arranging the elastic member in the cooking box body, and connecting two ends of the elastic member to the door body assembly and the locking hook part, the elastic member exerts a pulling force on the locking hook part in the first position in the direction from the second position to the first position, and the groove wall of the sliding groove limits the locking hook part, so that the locking hook part can be stably kept in the first position, preventing the locking hook part from loosening, and improving the reliability of the cooperation between the locking hook part and the locking part, so that the door body assembly can be firmly locked to the main body.

[0040] In the above technical solution, further, when the locking hook part is in the second position, the elastic member is stretched, and the elastic member can pull the locking hook part back to the first position.

[0041] In this technical solution, the relationship between the elastic member and the locking hook part is further limited. When the locking hook part is in the second position, the elastic member is stretched, and the elastic member exerts a pulling force on the locking hook part in the direction from the second position to the first position, and the elastic member can pull the locking hook part back to the first position. Specifically, when the user pushes the locking hook part to the second position and the door body assembly is unlocked from the main body, the user can pull the door body assembly to the open position, at this time, the elastic member can pull the locking hook part back to the first position automatically, so as to make the locking hook part cooperate with the locking part to lock the door body assembly when the door body assembly is in the closed position again. And when the door body assembly is locked to the main body, if the user pushes the locking hook part to the second position due to misoperation, the elastic member can also pull the locking hook part back to the first position automatically, so as to lock the door body assembly to the main body again.

[0042] In the above technical solution, further, during the movement of the door body assembly from the open position to the closed position, the locking member moves along the surface of the limiting member, and when the door body assembly moves to the closed position, the elastic member pulls the locking member back to the first position.

[0043] In the technical solution, the relationship between the elastic member and the hook portion is further limited. When the door body assembly is in the open position, the hook portion has returned to the first position relative to the door body assembly under the pulling force of the elastic member. During movement of the door body assembly from the open position to the closed position, the locking member in the hook portion first extends into the main body and contacts the limiting member, and the locking member moves along the surface of the limiting member. Since the elastic member always applies a pulling force to the hook portion, the locking member can be fitted to the surface of the limiting member during extension into the main body. When the door body assembly moves to the closed position, the elastic member pulls the locking member to return to the first position, the locking member cooperates with the limiting member, and the limiting member can limit the locking member to lock the door body assembly to the main body. In this way, the door body assembly can be automatically locked to the main body when it moves to the closed position without manual operation by the user, improving the user's convenience.

[0044] In the above technical solution, further, the cooking box body further comprises a guide surface provided on the locking member, the guide surface is configured as an inclined surface, and the guide surface abuts against the surface of the limiting member during movement of the door body assembly from the open position to the closed position.

[0045] In the technical solution, in order to facilitate movement of the locking member along the surface of the limiting member, the application provides a guide surface in the locking member, which abuts against the limiting member during movement of the locking member along the surface of the limiting member. Specifically, the guide surface is configured as an inclined surface, which abuts against the surface of the limiting member during movement of the door body assembly from the open position to the closed position. Since the guide surface is configured as an inclined surface, the resistance generated during movement of the locking member along the surface of the limiting member can be reduced, and the locking member can more easily extend into the main body.

[0046] In the above technical solution, further, the hook portion can also move to a third position relative to the door body assembly, and in the case where the hook portion is in the third position, the hook portion is fixed and separated from the lock catch portion.

[0047] In the technical solution, the hook portion is further limited. Understandably, when the user uses the cooking appliance, there is a need to lock the door body assembly to the main body, and therefore, another state of the hook portion is limited. In the case where the hook portion is in the third position, the hook portion is disabled and cannot cooperate with the lock catch portion to lock the door body assembly.

[0048] Specifically, the hook portion can also move to a third position relative to the door body assembly, and in the case where the hook portion is in the third position, the hook portion is separated from the lock catch portion and is fixed in the third position. In this case, the hook portion is disabled and cannot cooperate with the lock catch portion to lock the door body assembly to the main body.

[0049] By enabling the locking hook portion to be fixed at the third position and enabling the locking hook portion to be separated from the locking buckle portion when the locking hook portion is at the third position, the locking hook portion can be disabled to enable the door body assembly to be unlocked from the main body.

[0050] In the technical solution, further, the cooking box body further comprises a limiting groove in communication with the sliding groove, and a groove wall of the limiting groove is provided with a clamping groove; the locking hook portion comprises a connecting piece for connecting the pusher and the second mounting plate, and the connecting piece is provided with a limiting protrusion; when the locking hook portion is at the third position, the connecting piece moves into the limiting groove, and the limiting protrusion extends into the clamping groove to enable the locking hook portion to be kept at the third position.

[0051] In the technical solution, the structure of the cooking box body is further limited. In order to enable the locking hook portion to be fixed at the third position, the limiting groove is further arranged in the door body assembly, and the connecting piece for cooperating with the limiting groove is further arranged in the locking hook portion. The limiting groove is in communication with the sliding groove, and the locking hook portion comprises the connecting piece for connecting the pusher and the second mounting plate. When the locking hook portion is at the third position, the connecting piece moves into the limiting groove, and at this time, the connecting piece is clamped in the limiting groove, so that the locking hook portion can be fixed at the third position.

[0052] Further, in order to enable the connecting piece to be clamped in the limiting groove, the clamping groove is arranged on the groove wall of the limiting groove, and the limiting protrusion adapted to the clamping groove is arranged in the connecting piece. When the locking hook portion is at the third position, the limiting protrusion extends into the clamping groove, and the groove wall of the clamping groove limits the limiting protrusion, so that the locking hook portion can be fixed at the third position.

[0053] Further, when the locking hook portion is at the third position, the connecting piece has a spacing between the wall surface away from the clamping groove of the limiting groove. When it is needed to move the connecting piece out of the limiting groove, the connecting piece needs to be first moved in the direction away from the clamping groove, so that the limiting protrusion moves out of the clamping groove, and then the connecting piece is moved out of the limiting groove and into the sliding groove. After the connecting piece is moved into the sliding groove, the locking hook portion can normally move between the first position and the second position relative to the door body assembly, and the locking hook portion restores the locking effect on the door body assembly.

[0054] By arranging the limiting groove in communication with the sliding groove in the door body assembly, arranging the clamping groove on the groove wall of the limiting groove, and arranging the limiting protrusion adapted to the clamping groove on the connecting piece of the locking hook portion, the locking hook portion can be fixed at the third position through the cooperation of the clamping groove and the limiting protrusion.

[0061] In the technical solution, further, the cooking box body further comprises a handle, which is arranged on the outer door plate and located on one side of the outer door plate close to the hook portion or on one side of the outer door plate away from the hook portion.

[0062] In the technical solution, the structure of the cooking box body is further limited. The cooking box body further comprises a handle, which is arranged on the outer door plate. By arranging the handle on the outer door plate, the user can easily apply force to the door body assembly through the handle, and the user can move the door body assembly between the open position and the closed position through the handle.

[0063] In one possible technical solution, the handle is arranged on one side of the outer door plate close to the hook portion. In this way, the user can push the hook portion while placing the hand on the handle, that is, the user first pushes the hook portion to the second position to unlock the door body assembly, and then pulls the door body assembly to the open position. Since the handle is close to the hook portion, the user can perform the above door opening operation by using only one hand, which facilitates the user to open the door.

[0064] In another possible technical solution, the handle is arranged on one side of the outer door plate away from the hook portion. In this way, it is difficult for children to unlock the door body assembly, and the user can also avoid unlocking the door body assembly due to misoperation.

[0065] The second aspect of the present application also provides a cooking appliance comprising the cooking box body according to the first aspect of the present application.

[0066] The cooking appliance according to the second aspect of the present application has all the beneficial effects of the cooking box body.

[0067] The cooking appliance comprises a microwave oven or a microwave steaming and baking all-in-one machine.

DETAILED DESCRIPTION

[0090] 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.

[0091] In the following description, many specific details are set forth in order to provide 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 scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0092] The following refers to Figures 1 to 18 The cooking box 100 and the cooking appliance provided according to some embodiments of the present application are described.

[0093] In an embodiment according to the present application, as Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the present application provides a cooking box 100, comprising: a main body 110; a door assembly 120 movably connected with the main body 110, the door assembly 120 being movable between an open position and a closed position; a locking catch 130 provided on the main body 110; a locking hook 140 provided on the door assembly 120, the locking hook 140 being movable relative to the door assembly 120 between a first position and a second position; in the case where the door assembly 120 is in the closed position and the locking hook 140 is in the first position, at least part of the locking hook 140 extends into the main body 110, and at least part of the locking catch 130 protrudes away from the door assembly 120 to limit the locking hook 140, so that the door assembly 120 is locked to the main body 110; in the case where the door assembly 120 is in the closed position and the locking hook 140 is in the second position, the locking hook 140 is separated from the locking catch 130, so that the door assembly 120 is unlocked relative to the main body 110, and the door assembly 120 can be moved to the open position under the action of an external force.

[0094] The cooking box 100 provided by the present application can be used in a cooking appliance, and the cooking box 100 comprises a main body 110 and a door assembly 120, wherein the door assembly 120 is movably connected with the main body 110, the main body 110 comprises a cooking cavity, and the door 125 is used to open or close the cooking cavity. Specifically, the door assembly 120 is movable between an open position and a closed position, when the door assembly 120 is in the open position, the door assembly 120 opens the cooking cavity, and when the door assembly 120 is in the closed position, the door assembly 120 closes the cooking cavity. The door assembly 120 can be hinged to the main body 110 by a connecting shaft, so that the door assembly 120 is rotatably connected relative to the main body 110, and a user can pull the door assembly 120 to rotate around the connecting shaft within a certain angle range relative to the main body 110, so as to move the door assembly 120 between the open position and the closed position.

[0095] Understandably, in the case where there are children at home, if the door assembly 120 can be directly opened (i.e. the door assembly 120 can be opened by only one step of operation), it is easy to cause the children to mistakenly open the door assembly 120. In the case where the cooking appliance is running, the cooking cavity is in a high-temperature state, and if the children mistakenly open the door assembly 120 due to misoperation, it is easy to cause the high temperature in the cooking cavity to scald the children. In order to avoid the above problems, the present application provides a structure for locking the door assembly 120 in the cooking box 100, so as to lock the door assembly 120, so that the user cannot open the door assembly 120 by only one step of operation.

[0096] Specifically, the cooking cabinet 100 further comprises a locking portion 130 and a hook portion 140, the locking portion 130 is adapted to the hook portion 140 to lock the door assembly 120. The locking portion 130 is arranged on the main body 110, and the hook portion 140 is arranged on the door assembly 120. The hook portion 140 can move between different positions to achieve the locking and unlocking of the door assembly 120. The specific structure of the locking portion 130 and the hook portion 140 is as follows: at least part of the locking portion 130 protrudes away from the door assembly 120. When the door assembly 120 is locked to the main body 110, at least part of the hook portion 140 extends into the main body 110, and the protruding locking portion 130 can limit the hook portion 140 extending into the main body 110. When the door assembly 120 has a tendency to move towards the opening position, the locking portion 130 limits the hook portion 140 to prevent the hook portion 140 from moving out of the main body 110. Since the hook portion 140 is arranged on the door assembly 120, the door assembly 120 can be locked to the main body 110 by the hook portion 140, thereby achieving the locking of the door assembly 120, and further preventing the user from opening the door assembly 120 by one-step operation.

[0097] Further, the cooperation between the hook portion 140 and the locking portion 130 is further limited. The hook portion 140 can move relative to the door assembly 120 between a first position and a second position to achieve the locking and unlocking of the door assembly 120. As shown in Figure 6 and Figure 7 Specifically, when it is necessary to lock the door assembly 120, the user can move the hook portion 140 to the first position when the door assembly 120 is located at the closed position. At this time, at least part of the hook portion 140 extends into the main body 110, and the locking portion 130 arranged on the main body 110 cooperates with the hook portion 140 extending into the main body 110. The locking portion 130 can limit the hook portion 140. When the door assembly 120 has a tendency to move towards the opening position, the locking portion 130 stops the hook portion 140, and the hook portion 140 cannot move out of the main body 110. Since the hook portion 140 is arranged on the door assembly 120, if the hook portion 140 cannot move out of the main body 110, the door assembly 120 cannot be separated from the main body 110, thereby achieving the technical effect of locking the door assembly 120 to the main body 110.

[0098] As shown in Figure 8 and Figure 9As shown, further, when it is required to unlock the door body assembly 120, the user can move the locking hook portion 140 to the second position while the door body assembly 120 is located at the closed position. At this time, the locking hook portion 140 has a certain spacing with the protruding part of the locking catch portion 130, the locking hook portion 140 is separated from the locking catch portion 130, the locking catch portion 130 cannot continue to limit the locking hook portion 140, and the door body assembly 120 has been unlocked relative to the main body 110. When the locking hook portion 140 is located at the second position relative to the door body assembly 120, the user can exert a force on the door body assembly 120 in the direction of the open position. Since the locking catch portion 130 has already failed to continue to limit the locking hook portion 140, the door body assembly 120 has been unlocked relative to the main body 110, so that the door body assembly 120 can be moved relative to the main body 110 under the action of the external force, and the door body assembly 120 can be moved to the open position. That is, the user needs to use a two-step door opening method when opening the door body assembly 120. First, the locking hook portion 140 is moved to the second position relative to the door body assembly 120 to achieve the unlocking between the door body assembly 120 and the main body 110. Then, the door body assembly 120 is pulled to move the door body assembly 120 to the open position to complete the door opening step.

[0099] By providing the locking catch portion 130 in the main body 110 and the locking hook portion 140 in the door body assembly 120, the locking of the door body assembly 120 and the main body 110 can be achieved through the cooperation of the locking hook portion 140 and the locking catch portion 130, so as to avoid the user from opening the door body assembly 120 due to misoperation and prevent the user from being scalded by the high temperature in the cooking cavity. Moreover, since the locking hook portion 140 can be moved relative to the door body assembly 120 between the first position and the second position, the user needs to move the locking hook portion 140 to the second position before opening the door body assembly 120 to unlock the door body assembly 120 relative to the main body 110, and then open the door 125, thereby realizing the two-step door opening method of the door body assembly 120 and improving the safety of the product.

[0100] In an embodiment according to the present application, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the locking hook portion 140 comprises a locking piece 141 which protrudes out of the door body assembly 120 in the direction towards the main body 110. In the case that the door body assembly 120 is located at the closed position and the locking hook portion 140 is located at the first position, the locking piece 141 protrudes into the main body 110, and the locking catch portion 130 limits the locking piece 141.

[0101] In this embodiment, the structure of the hook portion 140 is defined. The hook portion 140 comprises a locking piece 141, which extends out of the door body assembly 120 in a direction towards the main body 110, and is configured to cooperate with the locking portion 130 to enable the door body assembly 120 to be locked to the main body 110. Specifically, when the door body assembly 120 is in the closed position, a user can move the hook portion 140 to a first position, at which the locking piece 141 extends into the main body 110 and cooperates with the locking portion 130 to be limited thereby. When the door body assembly 120 tends to move in a direction towards the open position under the action of an external force, the locking piece 141 is pulled by the door body assembly 120 to move in a direction out of the main body 110, and the locking portion 130 limits the movement of the locking piece 141 to prevent the locking piece 141 from moving, thereby enabling the door body assembly 120 to be locked to the main body 110.

[0102] In a possible embodiment, the locking piece 141 comprises a connecting rod 142 and a bent piece 143, which is arranged at one end of the connecting rod 142 towards the main body 110. When the locking piece 141 extends into the main body 110 with the locking portion 130 in the first position, the bent piece 143 is located on a side of the protrusion in the locking portion 130 away from the door body assembly 120. When the door body assembly 120 is pulled by an external force to tend to move in a direction towards the open position, the bent piece 143 abuts against the protrusion in the locking portion 130 to limit the movement of the bent piece 143, thereby achieving the technical effect of locking the door body assembly 120 to the main body 110.

[0103] By arranging the locking piece 141 in the hook portion 140, the technical effect of locking the door body assembly 120 to the main body 110 can be achieved by cooperation between the locking piece 141 and the locking portion 130.

[0104] In an embodiment according to the present application, as shown in Figure 12 and Figure 13 the locking portion 130 comprises a limiting piece 131, which protrudes in a direction away from the door body assembly 120 and is configured to limit the movement of the locking piece 141.

[0105] In this embodiment, the structure of the locking portion 130 is defined. In order to enable the locking portion 130 to limit the hook portion 140, the locking portion 130 is provided with a limiting piece 131 capable of cooperating with the hook portion 140. The limiting piece 131 protrudes in a direction away from the door assembly 120. When the door assembly 120 is in the closed position and the hook portion 140 is in the first position, the locking piece 141 in the hook portion 140 extends into the main body 110, and at this time, the bend in the locking piece 141 is located on the side of the limiting piece 131 away from the door assembly 120. When the door assembly 120 is pulled by external force and tends to move towards the open position, the bend 143 abuts against the limiting piece 131 to limit the bend 143 and thus limit the hook portion 140. Since the hook portion 140 is arranged on the door assembly 120, the door assembly 120 cannot move under the cooperation of the hook portion 140 and the limiting piece 131, thereby achieving the technical effect of locking the door assembly 120 to the main body 110.

[0106] By arranging the limiting piece 131 protruding in the direction away from the door assembly 120 in the locking portion 130, the hook portion 140 can be limited by the limiting piece 131, thereby achieving the technical effect of locking the door assembly 120 to the main body 110.

[0107] In an embodiment according to the present application, as shown in Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the locking portion 130 further comprises a first mounting plate 132 arranged on the main body 110. The main body 110 is provided with a first opening 112, and the first mounting plate 132 is provided with a second opening 133 corresponding to the first opening 112. The locking piece 141 can extend into the main body 110 through the first opening 112 and the second opening 133 in sequence.

[0108] In this embodiment, the structure of the locking portion 130 is further defined. In order to mount and fix the limiting piece 131, the locking portion 130 is further provided with the first mounting plate 132, which is used to mount the limiting piece 131. Specifically, as shown in Figure 6 、 Figure 16 and Figure 18 , the main body 110 comprises a front plate 111 arranged towards the door assembly 120. The first mounting plate 132 is mounted on the front plate 111. The limiting piece 131 is connected to the side of the first mounting plate 132 away from the door assembly 120, and protrudes from the surface of the first mounting plate 132.

[0109] Further, in order to enable the first mounting plate 132 to be mounted to the front plate 111, the present application further provides a plurality of mounting holes on the first mounting plate 132, which are used to connect the first mounting plate 132 to the front plate 111. Specifically, the mounting holes can be threaded holes, and the first mounting plate 132 can be connected to the front plate 111 by screws passing through the mounting holes to connect the first mounting plate 132 to the front plate 111.

[0110] Further, in order to enable the locking member 141 to extend into the main body 110 and cooperate with the limiting member 131, the present application provides a first opening 112 in the main body 110, which is arranged on the front plate 111, and a second opening 133 corresponding to the first opening 112 on the first mounting plate 132, and the locking member 141 can extend into the main body 110 through the first opening 112 and the second opening 133 in sequence. Moreover, the locking member 141 can move within a certain range in the first opening 112 and the second opening 133, and when the locking hook portion 140 moves between the first position and the second position when the door assembly 120 is in the closed position, the locking member 141 can move in the first opening 112 and the second opening 133.

[0111] Further, the plurality of mounting holes are located on both sides of the second opening 133, so that the first mounting plate 132 is balanced in force, and the first mounting plate 132 can be stably connected to the main body 110.

[0112] By providing the first mounting plate 132 in the locking hook portion 130, the limiting member 131 can be mounted and fixed by the first mounting plate 132. By providing the first opening 112 in the main body 110 and the second opening 133 corresponding to the first opening 112 in the first mounting plate 132, the locking member 141 can smoothly extend into the main body 110 through the first opening 112 and the second opening 133, so that the locking member 141 can normally cooperate with the limiting member 131 to realize the locking function of the door assembly 120.

[0113] In an embodiment according to the present application, as shown in Figure 7 , Figure 9 , Figure 14 and Figure 15 The cooking box 100 further comprises a sliding groove 121 arranged on the door assembly 120, and at least part of the locking hook portion 140 is located in the sliding groove 121, and the locking hook portion 140 can move along the sliding groove 121 between the first position and the second position.

[0114] In this embodiment, the structure of the door body assembly 120 is further defined. In order to enable the hook portion 140 to move between the first position and the second position relative to the door body assembly 120, the present application further provides a sliding groove 121 in the door body assembly 120, which is used to define the moving track of the hook portion 140. At least part of the hook portion 140 is located in the sliding groove 121, and the hook portion 140 can move along the sliding groove 121 between the first position and the second position. Specifically, the sliding groove 121 can be provided on the side wall or the top wall of the door body assembly 120, and at least part of the hook portion 140 is located in the sliding groove 121, and the groove wall of the sliding groove 121 limits the hook portion 140 located in the sliding groove 121, so that the hook portion 140 can move along the sliding groove 121 under the action of external force. As shown in Figure 7 when the hook portion 140 is located at the first position relative to the door body assembly 120, the hook portion 140 provided in the sliding groove 121 is located at the first end of the sliding groove 121, and during the movement of the hook portion 140 relative to the door body assembly 120 towards the second position, the hook portion 140 provided in the sliding groove 121 moves towards the direction away from the first end of the sliding groove 121, Figure 9 the direction of the arrow is the moving direction of the hook portion 140. In this way, on the one hand, the moving track of the hook portion 140 can be defined by the sliding groove 121, and on the other hand, the position of the hook portion 140 can be defined by the inner wall of the sliding groove 121, so that the hook portion 140 can stop at the first position.

[0115] By providing the sliding groove 121 in the door body assembly 120 and arranging at least part of the hook portion 140 in the sliding groove 121, the hook portion 140 can move along the sliding groove 121 between the first position and the second position, so that on the one hand, the moving track of the hook portion 140 can be defined by the sliding groove 121, and on the other hand, the position of the hook portion 140 can be defined by the inner wall of the sliding groove 121, so that the hook portion 140 can stop at the first position.

[0116] In an embodiment according to the present application, as shown in Figure 6 and Figure 8 the hook portion 140 further comprises a pushing member 144 for driving the locking member 141 to move, the pushing member 144 is located on the side of the sliding groove 121 facing the outside, and the locking member 141 is located on the side of the sliding groove 121 away from the outside.

[0117] In this embodiment, the structure of the hook portion 140 is further defined. In order to facilitate the user to move the hook portion 140, the present application provides a pushing piece 144 in the hook portion 140, through which the user can push the hook portion 140 to move relative to the door body assembly 120 between the first position and the second position. Wherein, the pushing piece 144 is located on the side of the sliding groove 121 facing the outside, the locking piece 141 is located on the side of the sliding groove 121 away from the outside, and the pushing piece 144 can drive the locking piece 141 to move. Specifically, when the user needs to lock the door body assembly 120 to the main body 110, the user applies a pushing force to the pushing piece 144, and the pushing piece 144 drives the locking piece 141 to move, the locking piece 141 extending into the main body 110 is driven by the pushing piece 144 to a position capable of cooperating with the limiting piece 131, and the limiting piece 131 can limit the locking piece 141 to lock the door body assembly 120 to the main body 110. When the user needs to unlock the door body assembly 120 from the main body 110, the user applies a pushing force in the opposite direction to the pushing piece 144, and the pushing piece 144 drives the locking piece 141 to move in the opposite direction, the locking piece 141 extending into the main body 110 is driven by the pushing piece 144 to a position away from the limiting piece 131, and the limiting piece 131 no longer limits the locking piece 141 to unlock the door body assembly 120 relative to the main body 110.

[0118] By providing the pushing piece 144 in the hook portion 140, the user can drive the locking piece 141 to move through the pushing piece 144, so that the hook portion 140 can move relative to the door body assembly 120 between the first position and the second position, thereby achieving the locking and unlocking of the door body assembly 120 relative to the main body 110.

[0119] In an embodiment according to the present application, as shown in Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the hook portion 140 further comprises a second mounting plate 145, the pushing piece 144 and the locking piece 141 are connected to the second mounting plate 145, and the second mounting plate 145 is located on the side of the sliding groove 121 away from the outside.

[0120] In this embodiment, the structure of the hook portion 140 is further limited. The hook portion 140 further comprises a second mounting plate 145, the pushing piece 144 and the locking piece 141 are mounted on the second mounting plate 145, the pushing piece 144 can push the second mounting plate 145 to move, the second mounting plate 145 drives the locking piece 141 to move, thereby realizing the technical effect that the locking piece 141 is moved by the pushing piece 144. Specifically, the second mounting plate 145 is located on the side of the sliding groove 121 away from the outside, and the second mounting plate 145 can cover the sliding groove 121 to avoid the second mounting plate 145 being stuck in the sliding groove 121 during movement relative to the sliding groove 121, so that the second mounting plate 145 can smoothly slide relative to the sliding groove 121, and then the second mounting plate 145 can smoothly drive the locking piece 141 to move under the pushing of the pushing piece 144.

[0121] By arranging the second mounting plate 145 in the hook portion 140, on the one hand, the pushing piece 144 and the locking piece 141 can be mounted and fixed, and on the other hand, the second mounting plate 145 can be moved by the pushing piece 144, and then the locking piece 141 is moved by the second mounting plate 145, thereby realizing the technical effect that the locking piece 141 is moved by the pushing piece 144.

[0122] In an embodiment according to the present application, as shown in Figure 1 and Figure 2 The cooking box body 100 further comprises an elastic piece 150, one end of the elastic piece 150 is connected with the door body assembly 120, and the other end is connected with the hook portion 140, and in the case that the hook portion 140 is located at the first position, the elastic piece 150 exerts a pulling force on the hook portion 140 in the direction from the second position to the first position.

[0123] In this embodiment, in order to improve the reliability of the cooperation between the hook portion 140 and the lock portion 130, the present application further arranges the elastic piece 150 in the cooking box body 100, and exerts a pulling force on the hook portion 140 by the elastic piece 150, so that the hook portion 140 can be stably stopped at the first position. Specifically, one end of the elastic piece 150 is connected with the door body assembly 120, and the other end is connected with the hook portion 140, and in the case that the hook portion 140 is located at the first position, the elastic piece 150 is stretched, and the elastic piece 150 exerts a pulling force on the hook portion 140 in the direction from the second position to the first position. The hook portion 140 has a tendency to continue to move under the action of the pulling force of the elastic piece 150, but the groove wall of the sliding groove 121 can limit the hook portion 140, so that the hook portion 140 can be stably kept at the first position, preventing the hook portion 140 from loosening, thereby improving the reliability of the cooperation between the hook portion 140 and the lock portion 130, and enabling the door body assembly 120 to be firmly locked to the main body 110.

[0124] In one possible embodiment, the second mounting plate 145 is provided with a hook 149, one end of the elastic member 150 is connected to the door body assembly 120, and the other end is connected to the hook 149 of the second mounting plate 145, the elastic member 150 exerts a pulling force on the second mounting plate 145, the second mounting plate 145 is connected to the pushing member 144 through the connecting member 147, the connecting member 147 is located in the sliding groove 121, and the groove wall of the sliding groove 121 limits the connecting member 147, so that the locking member is stably kept in the first position.

[0125] By arranging the elastic member 150 in the cooking box body 100 and connecting two ends of the elastic member 150 to the door body assembly 120 and the hook portion 140, the elastic member 150 exerts a pulling force on the hook portion 140 in the first position in the direction from the second position to the first position, and the groove wall of the sliding groove 121 limits the hook portion 140, so that the hook portion 140 can be stably kept in the first position, the problem of loosening of the hook portion 140 is prevented, and the reliability of cooperation between the hook portion 140 and the locking portion 130 is improved, so that the door body assembly 120 can be firmly locked to the main body 110.

[0126] In one embodiment according to the present application, when the hook portion 140 is in the second position, the elastic member 150 is stretched, and the elastic member 150 can pull the hook portion 140 to return to the first position.

[0127] In this embodiment, the relationship between the elastic member 150 and the hook portion 140 is further limited. When the hook portion 140 is in the second position, the elastic member 150 is stretched, the elastic member 150 exerts a pulling force on the hook portion 140 in the direction from the second position to the first position, and the elastic member 150 can pull the hook portion 140 to return to the first position. Specifically, when the user pushes the hook portion 140 to the second position and the door body assembly 120 is unlocked from the main body 110, the user can pull the door body assembly 120 to move to the open position, at this time, the elastic member 150 can pull the hook portion 140 to automatically return to the first position, so as to enable the hook portion 140 to cooperate with the locking portion 130 to lock the door body assembly 120 when the door body assembly 120 is again in the closed position. And when the door body assembly 120 is locked to the main body 110, if the user pushes the hook portion 140 to the second position due to misoperation, the elastic member 150 can also pull the hook portion 140 to automatically return to the first position, so as to enable the door body assembly 120 to be locked to the main body 110 again.

[0128] In one embodiment according to the present application, during movement of the door body assembly 120 from the open position to the closed position, the locking member 141 moves along the surface of the limiting member 131, and when the door body assembly 120 moves to the closed position, the elastic member 150 pulls the locking member 141 to return to the first position.

[0129] In this embodiment, the relationship between the elastic member 150 and the hook portion 140 is further defined. When the door body assembly 120 is in the open position, at this time, the hook portion 140 has been restored to the first position relative to the door body assembly 120 under the pulling force of the elastic member 150, during the movement of the door body assembly 120 from the open position to the closed position, the locking member 141 in the hook portion 140 first extends into the main body 110 and is in contact with the limiting member 131, and the locking member 141 moves along the surface of the limiting member 131. Since the elastic member 150 always exerts a pulling force on the hook portion 140, the locking member 141 can be fitted to the surface of the limiting member 131 during the extension into the main body 110. When the door body assembly 120 moves to the closed position, the elastic member 150 pulls the locking member 141 to restore to the first position, and the locking member 141 cooperates with the limiting member 131, and the limiting member 131 can limit the locking member 141 to lock the door body assembly 120 to the main body 110. In this way, the door body assembly 120 can be automatically locked to the main body 110 when it moves to the closed position, without the need for manual operation by the user, thereby improving the user's convenience.

[0130] In an embodiment according to the present application, as shown in Figure 4 , Figure 5 , Figure 6 and Figure 8 , the cooking cabinet 100 further comprises a guide surface 146 provided on the locking member 141, the guide surface 146 is configured as an inclined surface, and during the movement of the door body assembly 120 from the open position to the closed position, the guide surface 146 abuts against the surface of the limiting member 131.

[0131] In this embodiment, in order to facilitate the movement of the locking member 141 along the surface of the limiting member 131, the present application provides the guide surface 146 in the locking member 141, and during the movement of the locking member 141 along the surface of the limiting member 131, the guide surface 146 abuts against the limiting member 131. Specifically, the guide surface 146 is configured as an inclined surface, and during the movement of the door body assembly 120 from the open position to the closed position, the guide surface 146 abuts against the surface of the limiting member 131. Since the guide surface 146 is configured as an inclined surface, the resistance generated during the movement of the locking member 141 along the surface of the limiting member 131 can be reduced, so that the locking member 141 can more easily extend into the main body 110.

[0132] In an embodiment according to the present application, as shown in Figure 10 and Figure 11 , the hook portion 140 can also move to a third position relative to the door body assembly 120, and when the hook portion 140 is in the third position, the hook portion 140 is fixed and separated from the lock catch portion 130.

[0133] In this embodiment, the lock hook portion 140 is further defined. Understandably, the user will have the need to not lock the door body assembly 120 to the main body 110 when using the cooking appliance, and therefore, the present application also defines another state of the lock hook portion 140, in which the lock hook portion 140 is disabled and cannot cooperate with the lock catch portion 130 to lock the door body assembly 120 when the lock hook portion 140 is in the third position.

[0134] Specifically, the lock hook portion 140 is also movable relative to the door body assembly 120 to a third position, in which the lock hook portion 140 is separated from the lock catch portion 130 and the lock hook portion 140 is fixed in the third position, in which case the lock hook portion 140 is disabled and cannot cooperate with the lock catch portion 130 to lock the door body assembly 120 to the main body 110.

[0135] By enabling the lock hook portion 140 to be fixed in the third position and separated from the lock catch portion 130 when in the third position, the lock hook portion 140 can be disabled so that the door body assembly 120 is no longer locked to the main body 110.

[0136] In an embodiment according to the present application, as shown in Figure 4 , Figure 5 , Figure 10 , Figure 11 and Figure 15 , the cooking box 100 further comprises a limiting groove 122 in communication with the sliding groove 121, the groove wall of the limiting groove 122 is provided with a clamping groove 123; the lock hook portion 140 comprises a connecting piece 147 for connecting the pusher 144 and the second mounting plate 145, the connecting piece 147 is provided with a limiting protrusion 148, in the case that the lock hook portion 140 is in the third position, the connecting piece 147 moves into the limiting groove 122, and the limiting protrusion 148 extends into the clamping groove 123, so as to keep the lock hook portion 140 in the third position.

[0137] In this embodiment, the structure of the cooking box 100 is further defined. In order to enable the lock hook portion 140 to be fixed in the third position, the present application further provides a limiting groove 122 in the door body assembly 120 and a connecting piece 147 in the lock hook portion 140 for cooperating with the limiting groove 122. The limiting groove 122 is in communication with the sliding groove 121, and the lock hook portion 140 comprises the connecting piece 147 for connecting the pusher 144 and the second mounting plate 145, in the case that the lock hook portion 140 is in the third position, the connecting piece 147 moves into the limiting groove 122, at this time, the connecting piece 147 is clamped in the limiting groove 122, so that the lock hook portion 140 can be fixed in the third position.

[0138] Further, in order to enable the connecting piece 147 to be clamped in the limiting groove 122, the application is provided with a clamping groove 123 on the groove wall of the limiting groove 122, and a limiting protrusion 148 is arranged in the connecting piece 147 to be matched with the clamping groove 123. When the hook portion 140 is in the third position, the limiting protrusion 148 extends into the clamping groove 123, and the groove wall of the clamping groove 123 limits the limiting protrusion 148, so that the hook portion 140 can be fixed in the third position.

[0139] Further, when the hook portion 140 is in the third position, the connecting piece 147 has a spacing between the wall surface away from the clamping groove 123 of the limiting groove 122. When it is needed to move the connecting piece 147 out of the limiting groove 122, the connecting piece 147 needs to be first pushed to move in the direction away from the clamping groove 123, so that the limiting protrusion 148 moves out of the clamping groove 123, and then the connecting piece 147 is moved out of the limiting groove 122 and into the sliding groove 121. After the connecting piece 147 is moved into the sliding groove 121, the hook portion 140 can normally move between the first position and the second position relative to the door body assembly 120, and the hook portion 140 restores the function of locking the door body assembly 120. Figure 11 The arrow in the figure shows the moving direction of the connecting piece 147 in the process of moving the hook portion 140 towards the third position.

[0140] By arranging the limiting groove 122 in the door body assembly 120 to communicate with the sliding groove 121, arranging the clamping groove 123 on the groove wall of the limiting groove 122, and arranging the limiting protrusion 148 on the connecting piece 147 of the hook portion 140 to be matched with the clamping groove 123, the hook portion 140 can be fixed in the third position by the cooperation of the clamping groove 123 and the limiting protrusion 148.

[0141] In an embodiment according to the application, as shown in Figure 17 The cooking box 100 further comprises a lock cover 160 connected with the hook portion 140, the lock cover 160 is located on the side of the sliding groove 121 facing the outside, and the lock cover 160 covers the sliding groove 121.

[0142] In this embodiment, the structure of the cooking box 100 is further defined. The cooking box 100 is further provided with a lock cover 160, which is connected with the hook portion 140 and located on the side of the sliding groove 121 facing the outside. A user can move the hook portion 140 between the first position and the second position by pushing the lock cover 160. Specifically, the lock cover 160 is connected with the pushing piece 144. When a user needs to lock the door body assembly 120 to the main body 110, the user pushes the lock cover 160 to move, and the lock cover 160 drives the pushing piece 144 to move. Since the pushing piece 144 and the locking piece 141 are both connected with the second mounting plate 145, the pushing piece 144 can drive the locking piece 141 to move, so that the locking piece 141 moves to a position where it can cooperate with the limiting piece 131 in the lock catch, the hook portion 140 moves to the first position, and the door body assembly 120 is locked to the main body 110. When a user needs to unlock the door body assembly 120, the user pushes the lock cover 160 in the opposite direction to move, and the lock cover 160 drives the pushing piece 144 to move in the opposite direction. The pushing piece 144 drives the locking piece 141 to move in the opposite direction through the second mounting plate 145, the locking piece 141 is separated from the limiting piece 131, the hook portion 140 moves to the second position, and the door body assembly 120 is unlocked.

[0143] Further, the lock cover 160 can cover the sliding groove 121. In this way, on the one hand, the lock cover 160 can protect the hook portion 140 from impurities from the outside entering the door body assembly 120 through the sliding groove 121, and on the other hand, the lock cover 160 can shield the sliding groove 121 to beautify the door body assembly 120.

[0144] By providing the lock cover 160 and connecting the lock cover 160 with the hook portion 140, a user can drive the hook portion 140 to move between the first position and the second position by pushing the lock cover 160, which is convenient for the user to operate. Moreover, since the lock cover 160 can cover the sliding groove 121, on the one hand, the lock cover 160 can protect the hook portion 140 from impurities from the outside entering the door body assembly 120 through the sliding groove 121, and on the other hand, the lock cover 160 can shield the sliding groove 121 to beautify the door body assembly 120.

[0145] In an embodiment according to the present application, as shown in Figure 17 the door body assembly 120 includes an outer door plate 124, the hook portion 140 is arranged on the outer door plate 124; a door body 125 connected with the side of the outer door plate 124 facing the main body 110; a door seal 126 connected with the side of the door body 125 facing the main body 110, and the locking piece 141 sequentially passes through the door body 125 and the door seal 126.

[0146] In this embodiment, the structure of the door body assembly 120 is defined. The door body assembly 120 comprises an outer door plate 124, a door body 125 and a door seal 126, wherein the hook portion 140 is arranged on the outer door plate 124, the sliding groove 121 is arranged on the top wall or the side wall of the outer door plate 124, the second mounting plate 145 in the hook portion 140 is mounted on the outer door plate 124, and the second mounting plate 145 and the pushing piece 144 are arranged on the inner side and the side facing the outside of the sliding groove 121, respectively. The door body 125 is connected to the side of the outer door plate 124 facing the main body 110, and the door seal 126 is connected to the side of the door body 125 facing the main body 110, i.e., the door body 125 is located between the door seal 126 and the outer door plate 124. The locking piece 141 extends in the direction facing the main body 110, and the door body 125 and the door seal 126 are each provided with an avoiding opening, and the locking piece 141 passes through the door body 125 and the door seal 126 in sequence through the avoiding openings, so that the locking piece 141 can extend into the main body 110.

[0147] In one embodiment according to the present application, as shown in Figure 17 the cooking box body 100 further comprises a handle 170 arranged on the outer door plate 124, and the handle 170 is located on the side of the outer door plate 124 close to or away from the hook portion 140.

[0148] In this embodiment, the structure of the cooking box body 100 is further defined. The cooking box body 100 further comprises the handle 170 arranged on the outer door plate 124. By arranging the handle 170 on the outer door plate 124, the user can conveniently apply force to the door body assembly 120, and the user can move the door body assembly 120 between the open position and the closed position by pulling the door body assembly 120 through the handle 170.

[0149] In one possible embodiment, the handle 170 is arranged on the side of the outer door plate 124 close to the hook portion 140. In this way, the user can place his hand on the handle 170 while pushing the hook portion 140, i.e., the user first pushes the hook portion 140 to move to the second position to unlock the door body assembly 120, and then pulls the door body assembly 120 to move to the open position. Since the handle 170 is close to the hook portion 140, the user can perform the above-mentioned door opening operation by using only one hand, which is convenient for the user to open the door.

[0150] In another possible embodiment, the handle 170 is arranged on the side of the outer door plate 124 away from the hook portion 140, which makes it difficult for children to unlock the door body assembly 120, and also avoids the user from unlocking the door body assembly 120 by mistake due to misoperation.

[0151] In one possible embodiment, the cooking box 100 comprises a child lock (i.e. the lock portion 130), a front plate 111, a door seal 126, a door body 125, a child lock hook (i.e. the hook portion 140), a child lock spring (i.e. the elastic member 150), a door surface (i.e. the outer door plate 124), a handle (i.e. the handle 170), and a child lock cover 160 (i.e. the lock cover 160).

[0152] The child lock is used to fasten the oven door (i.e. the door body assembly 120) of the cooking appliance to the main body 110. The child lock is provided with a fastening surface 134 and a guide surface 135, and is fixed to the front plate 111 through a through hole.

[0153] The front plate 111 is arranged on the main body 110 and is provided with a through hole and a flange for fixing the child lock.

[0154] The door seal 126 is arranged on the oven door of the cooking appliance and is used to protect the internal structure. The door seal 126 is provided with a through hole through which the child lock hook passes.

[0155] The door body 125 is arranged on the oven door of the cooking appliance and is used to prevent microwave leakage. The door body 125 is provided with a through hole and a groove through which the child lock hook passes.

[0156] The child lock hook is used to fasten the oven door to the main body 110.

[0157] The child lock spring is used for elastic opening and closing of the child lock hook and the child lock. When the child lock hook is not under stress, it can automatically reset.

[0158] The door surface is used to protect the internal structure of the door body assembly 120. The door surface is provided with a track (i.e. the sliding groove 121) on which the child lock hook slides. The door surface is internally provided with a spring hook to which the child lock spring is connected. The child lock spring can automatically reset the child lock hook. The door surface is also provided with a failure groove (i.e. the limiting groove 122). When the child lock hook passes through the L-shaped track and enters the failure groove, it can be stuck in the failure groove.

[0159] The child lock spring is installed between the spring hook (i.e. the hook 149) of the child lock hook and the spring buckle 127 of the door surface. When normally installed, the child lock spring is in a slight tensile state, so that the child lock hook always maintains an automatic reset state.

[0160] When the oven door is closed and the child lock hook slides to the first position relative to the oven door, the lock (i.e. the locking member 141) of the child lock hook will automatically fasten with the fastening surface 134 of the child lock under the action of the tensile force of the child lock spring and on the basis of the guide surface 135 of the child lock. Under the resistance of the fastening surface 134 and the child lock spring, the oven door cannot be directly opened.

[0161] The child lock switch (i.e. the pusher 144) of the child lock hook is internally exposed to the outside of the door surface. After the child lock spring is installed, the end of the child lock switch protrudes out of the track under the pulling force of the child lock spring. The size of the protruding track in the sliding direction of the child lock switch is greater than the sliding stroke, so that the child lock hook remains in the track and cannot be pulled out of the door surface.

[0162] When the child lock hook slides to the second position relative to the oven door, the corresponding lock catch of the child lock hook is away from the latching surface 134 of the child lock catch. At this time, the unlocking is completed and the oven door can be pulled open. After the door is pulled open, the child lock switch of the child lock hook can be released. Under the elastic force of the child lock spring, the child lock switch automatically rebounds to the initial position and is latched under the action of the guide surface 146 and the spring again when the door is closed next time. Figure 9 The sliding direction is shown to the left, but in practice, the sliding direction can be derived in any direction, such as to the right, upward, or downward.

[0163] The switch of the child lock hook can be manually slid down into the failure groove of the door surface. The lock catch of the child lock hook is in a misaligned state with the latching surface 134 of the child lock catch and cannot be latched, so that the child lock hook is disabled. Since the failure groove is provided with a recess (i.e. the clamping groove 123), the limiting rib (i.e. the limiting protrusion 148) of the child lock hook enters the recess and is limited by the pulling force of the child lock spring. If there is no counterforce to exit the limiting rib from the recess, the child lock hook will remain unable to reset and can be locked for a long time. At this time, the child lock hook is equivalent to a disabled state. If the child lock hook needs to be reset, an external force is required to exit the limiting rib from the recess and return to the track.

[0164] The size of the child lock cover 160 is greater than the track in the door surface. The child lock cover 160 is latched onto the top of the child lock hook from the outside of the door surface. The child lock hook and the child lock cover 160 are clamped on both sides of the track and cannot be pulled out of the door surface. In addition, the child lock cover 160 can prevent accidental contact with the track and internal structural components of the door surface, thereby achieving the functions of protection and aesthetics.

[0165] The second aspect of the present application also provides a cooking appliance comprising the cooking cabinet 100 provided in the first aspect of the present application.

[0166] The cooking appliance provided in the second aspect of the present application comprises the cooking cabinet 100 provided in the first aspect of the present application, and thus has all the beneficial effects of the cooking cabinet 100.

[0167] The cooking appliance comprises a microwave oven or a microwave steaming and baking all-in-one machine.
