TECHNICAL FIELD
[0001] The present application relates to the technical field of cooking appliances, in particular to a locking assembly and a cooking appliance. BACKGROUND
[0002] In the related art, the microwave oven is not reasonably arranged, and the microwave oven can be opened by pulling the door body, and children are easy to touch the keys or the door handle, which has a safety hazard. SUMMARY
[0003] The present application aims to at least solve one of the problems in the prior art or related art.
[0004] To this end, the first aspect of the present application provides a locking assembly.
[0005] The second aspect of the present application provides a cooking appliance.
[0006] Therefore, the first aspect of the present application provides a locking assembly, comprising: a mounting base plate; a door body located on one side of the mounting base plate, the door body being provided with a door hook; a first lock structure provided on the mounting base plate, the first lock structure comprising a matching piece capable of moving relative to the mounting base plate between a first position and a second position; a second lock structure provided on the mounting base plate, the second lock structure comprising a trigger piece and a locking piece, the trigger piece being used to drive the locking piece to move between a third position limiting the movement of the door hook and a fourth position releasing the limitation of the movement of the door hook; wherein, in the first position, the matching piece limits the movement of the locking piece from the third position to the fourth position, and in the second position, the matching piece releases the limitation of the locking piece, and the trigger piece can drive the locking piece to move from the third position to the fourth position.
[0007] The locking assembly provided by the present application comprises a mounting base plate, a door body, a first lock structure and a second lock structure.
[0008] After the door body is locked, the matching piece of the first lock structure limits the movement of the locking piece in the first position, specifically, the movement of the locking piece from the third position to the fourth position, that is, the locking piece stays in the third position, at this time, the trigger piece cannot drive the locking piece to move to the fourth position. When the locking piece is located in the third position, the locking piece limits the movement of the door hook to block the door body, so that the door body cannot be opened, at this time, even if a child pulls the door body, the door body cannot be unlocked. That is, the door body, the first lock structure and the second lock structure cooperate to realize the function of a child lock, and in the case that the matching piece is in the first position and cooperates with the locking piece, the door body cannot be opened.
[0009] When the engaging member of the first lock structure is in the second position, the engaging member releases the restriction of the movement of the locking member. At this time, an external force acts on the triggering member, and the triggering member can drive the locking member to move from the third position to the fourth position. When the locking member moves to the fourth position, the restriction on the door hook is released. At this time, the door body can be unlocked by pulling the door body.
[0010] That is, when opening the door body, the engaging member needs to be moved to the second position first, and then the triggering member is used to drive the locking member to move to the fourth position, so that the locking assembly has the function of two-step door opening.
[0011] This arrangement can effectively solve the problem of unlocking the door body due to the accidental touch of the button or the door body by children in the related art, and can ensure the safety and reliability of the use of the cooking appliance including the locking assembly.
[0012] It can be understood that the locking member can move between the third position where the movement of the door hook is restricted and the fourth position where the restriction on the movement of the door hook is released. When the locking member is in a position other than the fourth position, the door body is in a state of being restricted from moving. That is, when the locking member moves to the third position and cooperates with the door hook of the door body, the door body cannot be opened even if it is pulled, that is, the door body will not be unlocked under the action of an external force, thereby fundamentally solving the problem of unlocking the door body due to the accidental touch of the button or the door body by children.
[0013] Specifically, the first lock structure and the second lock structure are both arranged on the mounting base, and the door body is located on one side of the mounting base. This arrangement can ensure the cooperation size of the first lock structure, the second lock structure, and the door body, and further ensure the cooperation size of the locking member, the engaging member, and the door hook, thereby providing effective and reliable structural support for effectively restricting the movement of the door body when the locking member is in the third position.
[0014] According to the above-mentioned locking assembly of the present application, the following additional technical features can also be provided:
[0015] In the above technical solution, further, the mounting base is provided with a first opening, and the first lock structure further includes: a seat body arranged on the mounting base; a support member rotationally connected with the seat body, and the engaging member is arranged on the support member; and a driving member arranged on the support member, and the driving member extends out of the outer surface of the mounting base through the first opening, wherein the driving member is used to drive the engaging member to move between the first position and the second position.
[0016] In this technical solution, the first lock structure further includes the seat body, the driving member, and the support member. The engaging member and the driving member are both arranged on the support member. Since the support member is rotationally connected with the seat body, when the driving member drives the support member to rotate relative to the seat body, the engaging member also rotates with the support member to move between the first position and the second position.
[0017] Specifically, the driving member extends out of the outer surface of the mounting substrate through the first opening, an external force is applied to the driving member, the driving member moves relative to the mounting substrate, and the supporting member is further driven to rotate relative to the seat body to drive the cooperating member to rotate.
[0018] It can be understood that after the door body is locked, the cooperating member is located at the first position, the cooperating member limits the movement of the locking member, and at this time, the door body cannot be opened. By actuating the driving member, the driving member drives the supporting member to rotate, the supporting member rotates to drive the cooperating member to move from the first position to the second position, and the locking member can move from the third position to the fourth position under the action of the triggering member. At this time, by pulling the door body, the purpose of unlocking the door body can be achieved.
[0019] Specifically, the cross-sectional area of the first opening is larger than the cross-sectional area of the driving member, which provides structural support for the movement of the driving member relative to the first opening.
[0020] Specifically, one of the supporting member and the seat body is provided with a rotating shaft, and the other of the supporting member and the seat body is provided with a shaft hole, and the rotating shaft is rotatably connected with the shaft hole to achieve the purpose of rotatably connecting the supporting member and the seat body.
[0021] In any of the above technical solutions, further, along the rotation direction of the supporting member, a part of the cooperating member is located on one side of the driving member.
[0022] In this technical solution, by reasonably setting the cooperation structure of the cooperating member and the driving member, a part of the cooperating member is located on one side of the driving member along the rotation direction of the supporting member. This setting makes the driving member rotate by a small angle, and the cooperating member and the locking member can be quickly abutted or quickly separated. This is conducive to improving the convenience of operating the locking assembly and reducing the size of the first opening.
[0023] In any of the above technical solutions, further, the second lock structure further comprises: a rotating member rotatably connected with the mounting substrate, and the triggering member drives the locking member to move through the rotating member; wherein, when the cooperating member is at the first position, the cooperating member limits the rotation of the rotating member, and when the cooperating member is at the second position, the cooperating member is separated from the rotating member.
[0024] In this technical solution, the second lock structure further comprises a rotating member rotatably connected with the mounting substrate, and the triggering member can drive the rotating member to rotate relative to the mounting substrate. The rotation of the rotating member can drive the locking member to move between the third position limiting the movement of the door hook and the fourth position releasing the limitation of the movement of the door hook.
[0025] That is, when the triggering member drives the rotating member to rotate relative to the mounting substrate, the locking member moves under the action of the rotating member to move between the third position and the fourth position.
[0026] In any of the above technical solutions, further, the locking member comprises a locking lever, the locking lever is rotationally connected with the mounting base plate, and the locking lever is located at one side of the rotating member; when in the first position, the locking lever abuts against the door hook; when in the second position, the triggering member can drive the locking lever to lift the door hook.
[0027] In this technical solution, the locking member comprises a locking lever, and the cooperation structure of the locking lever, the rotating member and the door hook is reasonably arranged, so that the locking lever is located at one side of the rotating member, and the rotating member can drive the locking lever to move relative to the mounting base plate.
[0028] When in the first position, the locking lever abuts against the door hook to limit the movement of the door hook, thereby playing a blocking role on the door body and preventing the door body from being opened; at this time, even if a child pulls the door body, the door body cannot be unlocked.
[0029] When in the second position, the rotating member is separated from the cooperation member, and the triggering member can drive the locking lever to move to lift the door hook; at this time, the door body can be unlocked by pulling the door body.
[0030] In any of the above technical solutions, further, the locking lever comprises a first locking segment and a second locking segment, the first locking segment is rotationally connected with the mounting base plate, and the weight of the second locking segment is greater than that of the first locking segment; wherein, when in the first position, the rotating member limits the movement of the second locking segment, and the second locking segment limits the movement of the door hook.
[0031] In this technical solution, the locking lever comprises a first locking segment and a second locking segment, and the cooperation structure of the first locking segment, the second locking segment and the door hook is reasonably arranged, so that when in the first position, the rotating member limits the movement of the second locking segment, and at this time, the second locking segment limits the movement of the door hook.
[0032] Since the weight of the second locking segment is greater than that of the first locking segment, when the cooperation member moves to the second position, the cooperation member and the rotating member are separated, the rotating member and the second locking segment are separated, and the second locking segment can be reset under the action of gravity. This arrangement can avoid the material investment for resetting the locking member, and has the advantages of convenient assembly and low production cost.
[0033] In any of the above technical solutions, further, the rotating member comprises a first rotating segment and a second rotating segment, the first rotating segment is rotationally connected with the mounting base plate, and the weight of the second rotating segment is greater than that of the first rotating segment; wherein, when in the first position, the cooperation member abuts against the top of the second rotating segment to limit the movement of the second rotating segment, and when in the second position, the cooperation member is separated from the second rotating segment.
[0034] In the technical solution, the rotating member comprises a first rotating segment and a second rotating segment, and the cooperation structure of the first rotating segment, the second rotating segment and the cooperation member is reasonably arranged, so that when the cooperation member is in the first position, the cooperation member abuts against the top of the second rotating segment to limit the movement of the second rotating segment, and at this time, the rotating member cannot be driven to rotate even if the touch trigger member is pressed, and thus the function of unlocking the door body cannot be realized.
[0035] In addition, since the weight of the second rotating segment is greater than that of the first rotating segment, when the cooperation member moves to the second position, the cooperation member is separated from the second rotating segment, and the second rotating segment can be reset under the action of gravity. This setting can avoid the investment of materials for resetting the rotating member, and has the advantages of convenient assembly and low production cost.
[0036] In any of the above technical solutions, further, the first lock structure further comprises an elastic member; when the driving member is located in the first region, the elastic member can drive the cooperation member to reset from the second position to the first position; and when the driving member is located in the second region, the elastic member can position the cooperation member at the second position.
[0037] In the technical solution, the first lock structure further comprises an elastic member, and when the driving member is located in the first region, the elastic member can drive the cooperation member to reset from the second position to the first position, that is, the elastic member provides power support for the cooperation member to return from the second position to the first position, and thus provides structural guarantee for the movement of the cooperation member between the first position and the second position.
[0038] Specifically, when the external force acting on the driving member is removed and the driving member is located in the first region, the elastic member drives the cooperation member to reset from the second position to the first position to position the locking member.
[0039] Further, when the driving member is located in the second region, the elastic member can position the cooperation member at the second position. That is, when the user does not need to use the child lock function, the driving member is moved to the second region to make the first lock structure and the second lock structure in an invalid state. This setting can meet different use requirements of users and improve the use applicability and use function of the product.

[0041] In the technical solution, the seat body is provided with a first connecting part, the support member is provided with a second connecting part, and the elastic member connects the first connecting part and the second connecting part. When the elastic member connects the first connecting part and the second connecting part, the elastic member, the first connecting part and the second connecting part cooperate to enable the elastic member to drive the cooperating member to reset from the second position to the first position when the driving member is located in the first region, and to enable the elastic member to limit the cooperating member in the second position when the driving member is located in the second region, thereby providing effective and reliable structural support.
[0042] Specifically, the first connecting part comprises a first connecting column, and the second connecting part comprises a second connecting column.

[0045] In the technical solution, the support member is provided with an avoiding gap, the second connecting part is located at the avoiding gap, and the avoiding gap has the function of avoiding the elastic member, so that the support member does not interfere with the elastic member when the driving member moves, and the use function of the elastic member can be ensured.
[0046] Further, the first locking structure further comprises a convex part, and the convex part connects the support member and the driving member. The convex part has the function of enhancing the connection strength of the support member and the driving member, avoids deformation of the locking assembly, and can ensure the fitting size of the product.
[0047] In addition, the convex part is located on the side of the avoiding gap away from the first connecting part, and the convex part does not interfere with the elastic member.

[0104] The following description refers to the accompanying drawings that show embodiments of the present application. Figures 1 to 27 A lock assembly and a cooking appliance according to some embodiments of the present application are described below.
[0105] Embodiment 1:
[0106] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 ,Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown in FIGS. 1-3, embodiments of the first aspect of the present application provide a locking assembly 100 comprising a mounting base 110, a door body 120, a first lock structure 130 and a second lock structure 160.
[0107] The door body 120 is located at one side of the mounting base 110, and the door body 120 is provided with a door hook 122.
[0108] The first lock structure 130 is arranged on the mounting base 110, and the first lock structure 130 comprises a cooperating piece 132, which is capable of moving relative to the mounting base 110 between a first position and a second position.
[0109] The second lock structure 160 is arranged on the mounting base 110, and the second lock structure 160 comprises a trigger piece 162 and a locking piece 164, the trigger piece 162 is used to drive the locking piece 164 to move between a third position for limiting the movement of the door hook 122 and a fourth position for releasing the limitation of the movement of the door hook 122.
[0110] In the first position, the cooperating piece 132 limits the movement of the locking piece 164 from the third position to the fourth position, and in the second position, the cooperating piece 132 releases the limitation of the locking piece 164, so that the trigger piece 162 can drive the locking piece 164 to move from the third position to the fourth position.
[0111] In detail, the locking assembly 100 comprises the mounting base 110, the door body 120, the first lock structure 130 and the second lock structure 160.
[0112] So that after locking the door body 120, the cooperating piece 132 of the first lock structure 130 limits the movement of the locking piece 164 in the first position, specifically, limits the movement of the locking piece 164 from the third position to the fourth position, that is, the locking piece 164 stays in the third position, at this time, the trigger piece 162 cannot drive the locking piece 164 to move to the fourth position. When the locking piece 164 is located in the third position, the locking piece 164 limits the movement of the door hook 122, so as to block the door body 120 and cannot open the door body 120, at this time, even if the child pulls the door body 120, the door body 120 cannot be unlocked. That is, the door body 120, the first lock structure 130 and the second lock structure 160 cooperate to realize the function of the child lock, and in the case that the cooperating piece 132 is in the first position and cooperates with the locking piece 164, the door body 120 cannot be opened.
[0113] When the engaging member 132 of the first lock structure 130 is in the second position, the engaging member 132 releases the restriction of the movement of the locking member 164. At this time, an external force acts on the triggering member 162, and the triggering member 162 can drive the locking member 164 to move from the third position to the fourth position. When the locking member 164 moves to the fourth position, the restriction on the door hook 122 is released, and at this time, the door body 120 can be unlocked by pulling the door body 120.
[0114] That is, when opening the door body 120, the engaging member 132 needs to be moved to the second position first, and then the triggering member 162 is used to drive the locking member 164 to move to the fourth position, so that the locking assembly 100 has the function of two-step door opening.
[0115] This setting can effectively solve the problem that children mistakenly touch the keys or the door body 120 to unlock the door body 120 in the related art, and can ensure the safety and reliability of the use of the cooking utensil including the locking assembly 100.
[0116] It can be understood that the locking member 164 can move between the third position where the movement of the door hook 122 is restricted and the fourth position where the movement of the door hook 122 is released. When the locking member 164 is in a position other than the fourth position, the door body 120 is in a state of being restricted from moving. That is, when the locking member 164 moves to the third position and cooperates with the door hook 122 of the door body 120, the door body 120 cannot be opened even if it is pulled, that is, the door body 120 will not be unlocked under the action of an external force, thereby fundamentally solving the problem that children mistakenly touch the keys or the door body 120 to unlock the door body 120.
[0117] Specifically, the first lock structure 130 and the second lock structure 160 are both arranged on the mounting base plate 110, and the door body 120 is located on one side of the mounting base plate 110. This setting can ensure the cooperation size of the first lock structure 130, the second lock structure 160, and the door body 120, and further ensure the cooperation size of the locking member 164, the engaging member 132, and the door hook 122, thereby providing effective and reliable structural support for the locking member 164 to effectively restrict the movement of the door body 120 when the locking member 164 is in the third position.

[0123] Wherein, when in the first position, the matching piece 132 limits the movement of the locking piece 164 from the third position to the fourth position, and when in the second position, the matching piece 132 releases the limitation of the locking piece 164, so that the trigger piece 162 can drive the locking piece 164 to move from the third position to the fourth position.
[0124] Further, Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 and Figure 22 As shown, the mounting base plate 110 is provided with a first opening, and the first locking structure 130 further comprises a seat body 134, a driving piece 138 and a supporting piece 136.

[0128] In detail, the first lock structure 130 further comprises a seat body 134, a driving member 138 and a supporting member 136. The cooperating member 132 and the driving member 138 are both arranged on the supporting member 136. Since the supporting member 136 is rotationally connected with the seat body 134, when the driving member 138 drives the supporting member 136 to rotate relative to the seat body 134, the cooperating member 132 also rotates with the supporting member 136 to move between the first position and the second position.
[0129] Specifically, the driving member 138 extends out of the outer surface of the mounting substrate 110 through the first opening, an external force acts on the driving member 138, the driving member 138 moves relative to the mounting substrate 110, and in turn drives the supporting member 136 to rotate relative to the seat body 134 to drive the cooperating member 132 to rotate.
[0130] It can be understood that after the door body 120 is locked, the cooperating member 132 is located at the first position, and the cooperating member 132 restricts the movement of the locking member 164, so that the door body 120 cannot be opened at this time. By pulling the driving member 138, the driving member 138 drives the supporting member 136 to rotate, and the supporting member 136 rotates to drive the cooperating member 132 to move from the first position to the second position, and the locking member 164 can move from the third position to the fourth position under the action of the triggering member 162, at this time, by pulling the door body 120, the purpose of unlocking the door body 120 can be achieved.
[0131] Specifically, the cross-sectional area of the first opening is larger than the cross-sectional area of the driving member 138, which provides structural support for the movement of the driving member 138 relative to the first opening.
[0132] Specifically, one of the supporting member 136 and the seat body 134 is provided with a rotating shaft, and the other of the supporting member 136 and the seat body 134 is provided with a shaft hole, and the rotating shaft is rotationally connected with the shaft hole to meet the purpose of rotationally connecting the supporting member 136 with the seat body 134.
[0133] Embodiment 3:
[0134] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 , on the basis of embodiment 2, embodiment 3 provides a locking assembly 100 comprising a mounting substrate 110, a door body 120, a first lock structure 130 and a second lock structure 160.

[0136] The first lock structure 130 is arranged on the mounting substrate 110, and the first lock structure 130 comprises a cooperating piece 132, which is capable of moving relative to the mounting substrate 110 between a first position and a second position.
[0137] The second lock structure 160 is arranged on the mounting substrate 110, and the second lock structure 160 comprises a triggering piece 162 and a locking piece 164, the triggering piece 162 is used to drive the locking piece 164 to move between a third position for limiting the movement of the door hook 122 and a fourth position for releasing the limitation of the movement of the door hook 122.
[0138] In the first position, the cooperating piece 132 limits the movement of the locking piece 164 from the third position to the fourth position, and in the second position, the cooperating piece 132 releases the limitation of the locking piece 164, so that the triggering piece 162 can drive the locking piece 164 to move from the third position to the fourth position.
[0139] The mounting substrate 110 is provided with a first opening, and the first lock structure 130 further comprises a seat body 134, a driving piece 138 and a supporting piece 136.
[0140] The seat body 134 is arranged on the mounting substrate 110.

[0142] The driving piece 138 is arranged on the supporting piece, and the driving piece 138 extends out of the outer surface of the mounting substrate 110 through the first opening, wherein the driving piece 138 is used to drive the cooperating piece 132 to move between the first position and the second position.
[0143] Further, as shown in Figure 23 , Figure 24 and Figure 25 , along the rotation direction of the supporting piece 136, a part of the cooperating piece 132 is located on one side of the driving piece 138.
[0144] In detail, by reasonably setting the cooperation structure of the cooperating piece 132 and the driving piece 138, along the rotation direction of the supporting piece 136, a part of the cooperating piece 132 is located on one side of the driving piece 138. This setting makes the driving piece 138 rotate a small angle, so as to realize the quick abutting or quick separation of the cooperating piece 132 and the locking piece 164. This is beneficial to improve the convenience of operating the locking assembly 100, and is also beneficial to reduce the size of the first opening.
[0145] Embodiment 4:
[0146] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, based on any of the above embodiments, embodiment 4 provides a locking assembly 100 including a mounting base 110 , a door body 120 , a first locking structure 130 and a second locking structure 160 .
[0147] The door body 120 is located on one side of the mounting base 110 , and the door body 120 is provided with a door hook 122 .
[0148] The first locking structure 130 is disposed on the mounting substrate 110 . The first locking structure 130 includes a fitting member 132 . The fitting member 132 is movable relative to the mounting substrate 110 between a first position and a second position.
[0149] The second lock structure 160 is provided on the mounting base 110 and includes a trigger 162 and a locking member 164 . The trigger 162 is used to drive the locking member 164 to move between a third position for restricting movement of the door hook 122 and a fourth position for releasing movement of the door hook 122 .
[0150] In the first position, the fitting member 132 restricts the locking member 164 from moving from the third position to the fourth position. In the second position, the fitting member 132 releases the restriction on the locking member 164, and the trigger member 162 can drive the locking member 164 to move from the third position to the fourth position.
[0151] Furthermore, if Figure 14 and Figure 15 As shown, the second lock structure 160 also includes: a rotating member 166, which is rotatably connected to the mounting base plate 110, and the trigger member 162 drives the locking member 164 to move through the rotating member 166; wherein, in the first position, the matching member 132 limits the rotation of the rotating member 166, and in the second position, the matching member 132 is separated from the rotating member 166.
[0152] In detail, the second lock structure 160 also includes a rotating member 166, which is rotatably connected to the mounting base 110. The trigger member 162 can drive the rotating member 166 to rotate relative to the mounting base 110. The rotation of the rotating member 166 can drive the locking member 164 to move between a third position that restricts the movement of the door hook 122 and a fourth position that releases the restriction on the movement of the door hook 122.
[0153] That is, when the trigger member 162 drives the rotating member 166 to rotate relative to the mounting substrate 110 , the locking member 164 moves under the action of the rotating member 166 to move between the third position and the fourth position.
[0154] Further, the locking member 164 comprises a locking lever, the locking lever is rotationally connected with the mounting base plate 110, and the locking lever is located at one side of the rotating member 166; in the first position, the locking lever abuts against the door hook 122, and in the second position, the triggering member 162 can drive the locking lever to lift the door hook 122.
[0155] Further, the locking member 164 comprises a locking lever, the locking lever is rotationally connected with the mounting base plate 110, and the locking lever is located at one side of the rotating member 166; in the first position, the locking lever abuts against the door hook 122, and in the second position, the triggering member 162 can drive the locking lever to lift the door hook 122.
[0156] In the first position, the locking lever abuts against the door hook 122, and limits the movement of the door hook 122, thereby playing a blocking role on the door body 120, and the door body 120 cannot be opened, at this time, even if the child pulls the door body 120, the door body 120 cannot be unlocked.
[0157] In the second position, the rotating member 166 is separated from the cooperating member 132, and the triggering member 162 can drive the locking lever to move to lift the door hook 122, at this time, the door body 120 can be unlocked by pulling the door body 120.
[0158] Further, as shown in Figure 3 , Figure 5 and Figure 10 , the locking lever comprises a first locking segment 168 and a second locking segment 170, the first locking segment 168 is rotationally connected with the mounting base plate 110, and the weight of the second locking segment 170 is greater than that of the first locking segment 168; wherein in the first position, the rotating member 166 limits the movement of the second locking segment 170, and the second locking segment 170 limits the movement of the door hook 122.
[0159] Further, the locking member 164 comprises a locking lever, the locking lever is rotationally connected with the mounting base plate 110, and the locking lever is located at one side of the rotating member 166; in the first position, the locking lever abuts against the door hook 122, and in the second position, the triggering member 162 can drive the locking lever to lift the door hook 122.
[0160] Because the weight of the second locking segment 170 is greater than that of the first locking segment 168, when the cooperating member 132 moves to the second position, the cooperating member 132 and the rotating member 166 are separated, the rotating member 166 and the second locking segment 170 are separated, and the second locking segment 170 can be reset under the action of gravity. This setting can avoid the material investment for resetting the locking member 164, and has the advantages of convenient assembly and low production cost.
[0161] Further, as shown in Figure 14 and Figure 15As shown, the rotating member 166 includes a first rotating section 172 and a second rotating section 174, the first rotating section 172 is rotationally connected with the mounting base plate 110, and the second rotating section 174 has a weight greater than that of the first rotating section 172; wherein, in the first position, the cooperating member 132 abuts against the top of the second rotating section 174 to limit the movement of the second rotating section 174, and in the second position, the cooperating member 132 is separated from the second rotating section 174.
[0162] As shown, the rotating member 166 includes a first rotating section 172 and a second rotating section 174, the first rotating section 172 is rotationally connected with the mounting base plate 110, and the second rotating section 174 has a weight greater than that of the first rotating section 172; wherein, in the first position, the cooperating member 132 abuts against the top of the second rotating section 174 to limit the movement of the second rotating section 174, and in the second position, the cooperating member 132 is separated from the second rotating section 174.
[0163] In addition, since the second rotating section 174 has a weight greater than that of the first rotating section 172, when the cooperating member 132 moves to the second position, the cooperating member 132 is separated from the second rotating section 174, and the second rotating section 174 can be reset under the action of gravity. This setting can avoid the material investment for resetting the rotating member 166, and has the advantages of convenient assembly and low production cost.

That is, the elastic part 176 provides power support for the cooperating part 132 to reset from the second position to the first position, thereby providing structural guarantee for the movement of the cooperating part 132 between the first position and the second position.
[0176] Specifically, when the external force acting on the driving part 138 is removed and the driving part 138 is located in the first region, the elastic part 176 drives the cooperating part 132 to reset from the second position to the first position to limit the lock 164.
[0177] In addition, when the driving member 138 is located in the second region, the elastic member 176 can limit the cooperating member 132 in the second position. That is, when the user does not need to use the child lock function, the driving member 138 is moved to the second region, so that the first lock structure 130 and the second lock structure 160 are in an invalid state. This setting can meet the different use requirements of users, improve the use applicability and use function of the product.

[0225] It can be understood that the cavity body forms the cooking cavity, and in the case that the door body 120 is unlocked, food can be placed into the cooking cavity and taken out of the cooking cavity.
[0226] In addition, the box structure is provided with a clamping groove, and the door hook 122 of the door body 120 can be clamped and connected with the clamping groove. When the locking member is located at the third position, the locking member limits the movement of the door hook 122, so as to block the door body 120 and prevent the door body 120 from being opened. At this time, even if the child pulls the door body 120 assembly, the door hook 122 cannot move relative to the clamping groove, and the door hook 122 is clamped in the clamping groove. When the locking member moves to the fourth position, the limitation on the door hook 122 is released, and an external force greater than the locking force of the door hook 122 and the clamping groove is applied to the door body 120, so as to achieve the purpose of unlocking the door body 120. That is, the first lock structure 130, the second lock structure 160, the door hook 122 and the clamping groove cooperate to make the cooking appliance have a two-step door opening function.
[0227] Further, as shown in Figures 2 to 6 、 Figure 10 、 Figure 11 and Figure 13 , the first lock structure 130 and the second lock structure 160 are located at the back of the control panel 250, the first part 112 of the mounting substrate is connected to the bottom of the cavity body, and the second part 114 of the mounting substrate is connected to the opening end of the cavity body; wherein the first lock structure 130 is connected to the first part 112 of the mounting substrate, and the second lock structure 160 is connected to the second part 114 of the mounting substrate.
[0228] Further, the positional relationship of the cavity body, the first lock structure 130, the second lock structure 160, the control panel 250 and the mounting substrate 110 is limited. Specifically, the first part 112 of the mounting substrate is connected to the bottom of the cavity body, the second part of the mounting substrate is connected to the opening end of the cavity body, the first lock structure 130 is connected to the first part 112 of the mounting substrate, and the second lock structure 160 is connected to the second part 114 of the mounting substrate.
[0229] Specifically, the first part 112 and the second part of the mounting substrate are integrally formed. Alternatively, the first part 112 and the second part of the mounting substrate are two independent plate bodies.
[0230] Specifically, the cooking appliance includes a microwave oven, an oven, a steamer, or a steam oven, etc., which are not listed one by one here.
[0231] Embodiment 9
[0232] The present application can prevent children from opening the door by reasonably setting the structure of the locking assembly 100, has the requirement of two-step door opening, and can be operated by one hand or both hands, that is, can be unlocked by one hand or both hands. It has little change to the whole cooking appliance and has strong universality.
[0233] The locking assembly 100 comprises a resilient member 176, which comprises a tension spring always kept in a tension state. For the resilient member 176, when the resilient member 176 connects the first connecting part 140 and the second connecting part 142, the engaging member 132 can be driven to move from the second position to the first position in the first direction; when the resilient member 176 connects the first connecting part 140 and the third connecting part, the engaging member 132 is driven to move in the second direction, the first direction is the counterclockwise direction, and the second direction is the clockwise direction.
[0234] When the driving member 138 rotates to a certain angle in the direction of the door handle, the engaging member 132 no longer restricts the rotation of the rotating member 166. Pressing the trigger member 162 makes the rotating member 166 rotate, forcing the locking lever to rotate to push the door hook 122 out. In this way, the door body 120 can be pulled open.
[0235] The application realizes the problem of opening the cooking appliance with a child lock function in two steps. The child lock is to protect children from opening the cooking appliance. It can be unlocked with one hand or two hands.
[0236] The first lock structure 130 is installed on the bottom plate of the cooking appliance, such as a microwave oven, and the microwave oven is small. The space behind the control panel 250 is utilized. The position of installing the first lock structure 130 is the bottom plate below the control panel 250 of the microwave oven.
[0237] The microwave oven with the lock structure can normally close the door. When closing the door, only the limiting function part of the lock structure works. After closing the door, the door hook 122 of the door body 120 is limited by the lock structure, and only the driving member 138 can be actuated to unlock the lock structure.
[0238] The microwave oven provided with the first lock structure 130 and the second lock structure 160, the first lock structure 130 limits the locking member 164, so that the door can be normally closed. During the closing process, the first lock structure 130 and the second lock structure 160 do not work. The trigger member 162 needs to move the driving member 138 of the first lock structure 130 to open the door due to the limiting action of the engaging member 132 of the first lock structure 130 on the rotating member 166 of the second lock structure 160.
[0239] The cooking appliance further comprises a first micro switch 220, a second micro switch 230 and a third micro switch 240, the number of door hooks 122 is multiple, the multiple door hooks 122 comprise upper door hooks and lower door hooks, the lower door hooks cooperate with the locking member 164, the upper door hooks cooperate with the first micro switch 220, and the locking member 164 cooperates with the second micro switch 230 and the third micro switch 240.
[0240] After the door is closed, the door hook triggers the first micro switch 220, and the locking member 164 can trigger the second micro switch 230 and the third micro switch 240. The first micro switch 220 is electrically connected with a microwave generator of the cooking appliance. The second micro switch 230 and the third micro switch 240 are electrically connected with a motor and a stove lamp.
[0241] Specifically, the locking assembly 100 comprises a mounting base plate 110, a door body 120, a first lock structure 130 and a second lock structure 160.
[0242] After the door body 120 is locked, the matching member 132 of the first lock structure 130 limits the movement of the locking member 164 at the first position, specifically, limits the movement of the locking member 164 from the third position to the fourth position, that is, the locking member 164 stays at the third position, and the trigger member 162 cannot drive the locking member 164 to move to the fourth position. When the locking member 164 is at the third position, the locking member 164 limits the movement of the door hook 122, so as to block the door body 120 and prevent the door body 120 from being opened. At this time, even if a child pulls the door body 120, the door body 120 cannot be unlocked. That is, the door body 120, the first lock structure 130 and the second lock structure 160 cooperate to achieve the function of a child lock, and when the matching member 132 is at the first position and cooperates with the locking member 164, the door body 120 cannot be opened.
[0243] When the matching member 132 of the first lock structure 130 is at the second position, the matching member 132 releases the limitation on the movement of the locking member 164. At this time, an external force acts on the trigger member 162, and the trigger member 162 can drive the locking member 164 to move from the third position to the fourth position. When the locking member 164 moves to the fourth position, the limitation on the door hook 122 is released, and at this time, the door body 120 can be unlocked by pulling the door body 120.
[0244] That is, when the door body 120 is opened, the matching member 132 needs to be moved to the second position first, and then the trigger member 162 is used to drive the locking member 164 to move to the fourth position, so that the locking assembly 100 has the function of two-step door opening.
[0245] This arrangement can effectively solve the problem that in the related art, a child mistakenly touches a button or the door body 120 to unlock the door body 120, and can ensure the safety and reliability of the cooking appliance comprising the locking assembly 100.
[0246] It can be understood that the locking member 164 can move between a third position for limiting the movement of the door hook 122 and a fourth position for releasing the limitation of the movement of the door hook 122. When the locking member 164 is in a position other than the fourth position, the door body 120 is in a state of being limited to move. That is, when the locking member 164 moves to the third position and cooperates with the door hook 122 of the door body 120, the door body 120 cannot be opened even if the door body 120 is pulled, that is, the door body 120 cannot be unlocked under the action of an external force, thereby fundamentally solving the problem that the door body 120 is unlocked due to the accidental touch of the button or the door body 120 by a child.
[0247] Specifically, the first locking structure 130 and the second locking structure 160 are arranged on the mounting base plate 110, and the door body 120 is located on one side of the mounting base plate 110. This arrangement can ensure the cooperation size of the first locking structure 130, the second locking structure 160 and the door body 120, and further ensure the cooperation size of the locking member 164, the cooperating member 132 and the door hook 122, thereby providing effective and reliable structural support for effectively limiting the movement of the door body 120 when the locking member 164 is in the third position.
