DETAILED DESCRIPTION

[0044] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying 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.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0046] Refer to the following Figures 1 to 22 The lock structure 100 and the cooking appliance provided according to some embodiments of the present invention are described.

[0047] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an embodiment of the present invention, a lock structure 100 is proposed, comprising: a limiting member 110, a locking member 120, an operating member 130 and a first elastic member 140. The locking member 120 is rotatably connected to the to-be-installed portion 310. When the locking member 120 is in the first position, the first end of the locking member 120 is locked with the limiting member 110. When the locking member 120 is in the second position, the first end of the locking member 120 is separated from the limiting member 110. The operating member 130 is used to push the second end of the locking member 120. When the operating member 130 is in the to-be-operated position, the locking member 120 is in the first position. When the operating member 130 is in the pushing position, the locking member 120 is in the second position. The first elastic member 140 is connected to the locking member 120. When the locking member 120 is in the first position, the first elastic member 140 is in a first elastic state. When the locking member 120 is in the second position, the first elastic member 140 is in a second elastic state. The deformation of the first elastic member 140 in the second elastic state is greater than the deformation in the first elastic state.

[0048] The lock structure 100 proposed in this embodiment is applied to a cooking appliance and is used as a child lock of the cooking appliance.

[0049] Specifically, the cooking appliance includes a door body assembly 300 and a cavity assembly 200. The door body assembly 300 is connected to the cavity assembly 200 in an opening and closing manner. The limit member 110 and the locking member 120 need to be locked with each other, so the limit member 110 is assembled to one of the door body assembly 300 and the cavity assembly 200, and the locking member 120 is assembled to the other of the door body assembly 300 and the cavity assembly 200.

[0050] In this embodiment, the limiting member 110 is provided on the cavity assembly 200, and the locking member 120 is provided on the door assembly 300 for exemplary description. The limiting member 110 is provided on the door assembly 300 in the same manner.

[0051] The door assembly 300 can drive the locking member 120 to move. When the door assembly 300 closes the cavity assembly 200, the locking member 120 can move. Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, when the locking member 120 moves to the first position, the locking member 120 is locked with the limiting member 110, and the limiting member 110 restricts the movement of the locking member 120. At this time, it is difficult for the user to pull the door assembly 300. The door assembly 300 and the cavity assembly 200 are in a locked state, and the user cannot open the cavity assembly 200 by pulling the door assembly 300. Fig.11 , Fig.12 and Fig.13 As shown, when the locking member 120 moves to the second position, the locking member 120 is separated from the limiting member 110, and the limiting member 110 no longer limits the locking member 120. At this time, the user can complete the door opening action.

[0052] The operating member 130 and the first elastic member 140 can drive the locking member 120 to rotate. When the user needs to perform the door opening operation, the operating member 130 can be pressed, and the operating member 130 can push the locking member 120, so that the locking member 120 can rotate from the first position to the second position. At this time, the first elastic member 140 undergoes elastic deformation, and the locking member 120 is separated from the limiting member 110, and the limiting member 110 will not interfere with the door opening process. When the user stops pressing the operating member 130, the first elastic member 140 can drive the locking member 120 to rotate and reset. At this time, the locking member 120 pushes the operating member 130, so that the operating member 130 moves from the pushing position to the waiting position for the user to press the operating member 130 next time.

[0053] Before opening the cavity assembly 200, the user needs to first perform an unlocking operation to release the limiting member 110 from limiting the locking member 120, and then open the cavity assembly 200. Opening the cavity assembly 200 requires two steps, which is conducive to improving the safety of the cooking appliance.

[0054] During the cooking process of the cooking appliance or after the cooking process is finished, the temperature of the food in the cooking cavity is high. At this time, if the user directly opens the door to take out the food, there is a risk of scalding. Therefore, the present invention cooperates with the above-mentioned limiter 110 and the door hook so that if the user wants to open the cavity assembly 200, he must unlock the cooking appliance before opening the cavity assembly 200. In this way, on the one hand, it can serve as a reminder to the user, and on the other hand, it can prevent children from accidentally opening the cavity assembly 200, thereby greatly improving the safety of the cooking appliance.

[0055] Therefore, the lock structure 100 proposed in the present invention cooperates with the limit member 110 and the locking member 120 to increase the unlocking difficulty of the lock structure 100, prevent users, especially children, from accidentally opening the cavity assembly 200, and improve the safety of cooking utensils using the lock structure 100.

[0056] In a possible application, when the locking member 120 is in the first position, the deformation of the first elastic member 140 is small, and when the locking member 120 is in the second position, the deformation of the first elastic member 140 is large. That is, when the locking member 120 is in the first position and the second position, the first elastic member 140 is in an elastic deformation state, and in the absence of external force, the first elastic member 140 can limit the locking member 120 to the first position. Of course, in other embodiments, when the locking member 120 is in the first position, the first elastic member 140 is in the original state.

[0057] like Fig.10 As shown, in the above embodiment, the limiting member 110 includes a first buckling portion 111, and the locking member 120 includes a second buckling portion 121. When the locking member 120 is in the first position, the second buckling portion 121 is buckled with the first buckling portion 111. When the locking member 120 is in the second position, the second buckling portion 121 is separated from the first buckling portion 111.

[0058] The limiting member 110 is provided with a first buckling portion 111 , and the locking member 120 is provided with a second buckling portion 121 , which can be buckled with the first buckling portion 111 .

[0059] When the locking member 120 is located at the first position, the second buckle part 121 and the first buckle part 111 are buckled with each other, the first buckle part 111 limits the second buckle part 121, and the second buckle part 121 is not easy to move relative to the first buckle part 111. At this time, the user cannot pull the door body assembly 300. When the locking member 120 is located at the second position, the rotated second buckle part 121 is separated from the first buckle part 111. At this time, the first buckle part 111 no longer limits the first buckle part 111, and the user can open the cavity assembly 200 by pulling the door body assembly 300.

[0060] In a possible application, the first elastic member 140 is a torsion spring, and a clamping portion 124 is provided on the locking member 120 . The torsion spring has two fixed legs, one of which is inserted into the clamping portion 124 , and the other is connected to the door body assembly 300 .

[0061] like Fig.10 As shown, in a possible embodiment, optionally, the limit member 110 also includes: a mounting portion 112, the mounting portion 112 is connected to the first buckling portion 111, the mounting portion 112 is annular, and when in the first position and the second position, the second buckling portion 121 passes through the mounting portion 112, and the mounting portion 112 is used to limit the rotation angle of the locking member 120.

[0062] The first buckling portion 111 is mounted on the mounting portion 112 , and the first buckling portion 111 and the mounting portion 112 may be an integrally formed structure.

[0063] When the locking member 120 is in the first position and the second position, the second buckling portion 121 passes through the annular structure on the mounting portion 112, that is, a portion of the locking member 120 passes through the mounting portion 112. When the locking member 120 rotates relative to the mounting member, the mounting portion 112 can limit the maximum rotation angle of the locking member 120, that is, the locking member 120 can abut against the mounting portion 112 after rotating a certain angle.

[0064] By limiting the rotation angle of the locking member 120 through the mounting portion 112 , it is possible to prevent the locking member 120 from rotating too much, and to prevent the operating member 130 and the locking member 120 from being misaligned or separated, thereby facilitating improving the matching stability between the operating member 130 and the locking member 120 .

[0065] When opening the door, the locking member 120 is first rotated by the operating member 130 to separate the locking member 120 from the first buckling portion 111 , and then when the door assembly 300 is pulled, the first buckling portion 111 extends out of the annular structure on the mounting portion 112 .

[0066] Combination Fig.10 and Fig.17 As shown, in a possible embodiment, optionally, a locking surface 113 and a guiding inclined surface 114 are provided on the first locking portion 111 , the guiding inclined surface 114 is connected to the locking surface 113 , and the second locking portion 121 can slide along the guiding inclined surface 114 and lock with the locking surface 113 .

[0067] A snap-fitting surface 113 is provided on the first snap-fitting portion 111, and the snap-fitting surface 113 is a plane. When the locking member 120 is located at the first position, the locking member 120 and the snap-fitting surface 113 are released, and the snap-fitting surface 113 limits the locking member 120. The contact surface between the snap-fitting surface 113 and the locking member 120 is a plane, which is beneficial to improve the matching stability of the snap-fitting surface 113 and the locking member 120.

[0068] A guiding slope 114 is also provided on the first buckling portion 111. During the door closing process, the locking member 120 moves toward the limiting member 110. When the second buckling portion 121 contacts the guiding slope 114, the guiding slope 114 guides the second buckling portion 121 so that the second buckling portion 121 can continue to slide along the guiding slope 114.

[0069] When the second buckling portion 121 slides along the guide slope 114, the locking member 120 rotates and the deformation of the first elastic member 140 gradually increases. When the second buckling portion 121 passes over the guide slope 114, the second buckling portion 121 automatically rotates to the first position under the drive of the first elastic member 140, so that the second buckling portion 121 automatically buckles with the first buckling portion 111.

[0070] By providing a guide slope 114 on the first snap-fitting portion 111, during the door closing process, the user does not need to drive the locking member 120 to rotate by pressing the operating member 130. The locking member 120 can automatically snap into the first snap-fitting portion 111, which simplifies the user's operation and helps to improve the user's convenience in using the cooking appliance.

[0071] like Fig.10 As shown, in a possible embodiment, optionally, the lock structure 100 also includes: a second elastic member 150, the second elastic member 150 is located between the operating member 130 and the locking member 120, when the operating member 130 is in the standby position, the second elastic member 150 is in an original state, when the operating member 130 is in the pushing position, the second elastic member 150 is in an elastically deformed state.

[0072] A second elastic member 150 is disposed between the operating member 130 and the locking member 120. When the user does not press the operating member 130, the second elastic member 150 is in an original state, and the second elastic member 150 does not undergo elastic deformation. When the user presses the operating member 130, the second elastic member 150 is in an elastic deformation state, and the second elastic member 150 undergoes elastic deformation.

[0073] Specifically, when the user presses the operating member 130, the second elastic member 150 accumulates elastic potential energy. When the user stops pressing the operating member 130, the second elastic member 150 can drive the operating member 130 to move and reset, ensuring that the operating member 130 can move to the operating position, which is beneficial to improving the functional stability of the lock structure 100.

[0074] In a possible application, the second elastic member 150 is a compression spring, and the second elastic member 150 is sleeved on the operating member 130 .

[0075] In a possible application, when the operating member 130 is located at the waiting position, the operating member 130 does not contact the locking member 120 , and when the operating member 130 is located at the pushing portion, the operating member 130 contacts the locking member 120 and compresses the second elastic member 150 .

[0076] Combination Fig. 9 and Fig.10 As shown, in a possible embodiment, optionally, the operating member 130 includes a button 131 and a limiting portion 132, the button 131 is used to push the locking member 120, the limiting portion 132 is connected to the button 131, and is distributed along the circumference of the button 131, when the operating member 130 is in the operating position, the limiting portion 132 is in contact with the portion to be installed 310, and the limiting portion 132 is used to limit the button 131.

[0077] When the user needs to open the door, the locking member 120 can be driven to rotate by pressing the button 131, so that the locking member 120 can be separated from the limiting member 110. A limiting portion 132 is provided on the button 131, and the limiting portion 132 can contact the to-be-installed portion 310, thereby limiting the button 131 from being separated from the installation position;

[0078] Specifically, the button 131 can move between the waiting position and the pushing position. When the button 131 moves to the waiting position, the limiting portion 132 contacts the to-be-installed portion 310, so that the button 131 is limited in the waiting position and cannot continue to move in the direction away from the pushing position, thereby stably limiting the button 131 in the installation position and ensuring the functional stability of the lock structure 100.

[0079] Combination Fig.13 , Fig.14 , Fig.15 and Fig.16 As shown, in a possible embodiment, optionally, the lock structure 100 also includes: a boss 160, the boss 160 is connected to the operating member 130, when the operating member 130 is in the pushing position, the operating member 130 can rotate toward the invalid position, the rotation axis of the operating member 130 is arranged in the same direction as the length direction of the operating member 130, when the operating member 130 is in the invalid position, the boss 160 contacts the to-be-installed portion 310 to limit the movement of the operating member 130 to the to-be-operated position.

[0080] A boss 160 is provided on the operating member 130, and the boss 160 is used to contact the matching position on the to-be-installed portion 310, thereby limiting the operating member 130 to the invalid position. When the operating member 130 is in the invalid position, even if the operating member 130 stops being pressed, the operating member 130 will not be reset to the to-be-operated position.

[0081] Specifically, the user needs to press the operating member 130 so that the operating member 130 can move to the pushing position. If the user stops pressing the operating member 130 at this time, the operating member 130 will be reset to the waiting position under the action of the first elastic member 140 and the second elastic member 150. When there is a need to fix the operating member 130 in the second position, the operating member 130 needs to be pressed to the pushing position first. A rib position is provided on the to-be-pushed portion. At this time, the boss 160 and the rib position are in a staggered state. By rotating the operating member 130, the boss 160 is rotated to a position opposite to the rib position. The boss 160 and the rib position are abutted against each other, and the rib position limits the boss 160. At this time, if the user stops pushing the operating member 130, the operating member 130 will not move to the waiting position. Therefore, the locking member 120 can be kept in a position separated from the limiting member 110, that is, the locking member 120 is in an "invalid" state.

[0082] By disabling the locking member 120, the user no longer needs to press the operating member 130 when opening the cavity assembly 200, which makes it easier for the user to use the cooking utensil, improves the functional diversity of the cooking utensil, and meets the user's usage needs in different scenarios.

[0083] like Fig.10 As shown, in a possible embodiment, optionally, a side of the boss 160 facing away from the locking member 120 is provided with an inclined surface 161 , and the inclined surface 161 can slide relative to the mounting portion 310 .

[0084] An inclined surface 161 is provided on one side of the boss 160. When the boss 160 rotates to be opposite to the rib position, the inclined surface 161 on the boss 160 contacts the rib position. As the boss 160 rotates, the inclined surface 161 slides along the rib position. When the inclined surface 161 slides relative to the rib position, since the position of the rib position is fixed, the boss 160 moves toward the locking member 120 during the rotation process. During this process, the second elastic member 150 is gradually compressed, so that the boss 160 can be pressed against the rib position, thereby increasing the friction between the boss 160 and the rib position, so that the boss 160 can be stably maintained in the failure position.

[0085] Combination Fig.18 and Fig.19 As shown, in a possible embodiment, optionally, a groove 133 is provided at one end of the operating member 130 away from the locking member 120, and the groove 133 is used for inserting a workpiece so that the operating member 130 can rotate driven by the workpiece.

[0086] The first end of the operating member 130 is used to be pressed by the user, and the second end of the operating member 130 is used to push the locking member 120. A groove 133 is provided at the first end of the operating member 130. The user can use the button 131 to extend into the groove 133, and then drive the operating member 130 to rotate through the workpiece.

[0087] When the operating member 130 needs to be rotated to the disabled position, the workpiece can be used to drive the operating member 130 to rotate. By setting a groove 133 on the operating member 130, the user can conveniently use the workpiece and the operating member 130 in combination, which is beneficial to improving the convenience of the user when rotating the operating member 130.

[0088] Exemplarily, the groove 133 is in the shape of a straight line, so that a straight-line knife tool can be used to extend into the groove 133 and drive the operating member 130 to rotate.

[0089] like Fig.10As shown, in a possible embodiment, optionally, the locking member 120 further includes: a bending portion 122 and a locking portion 123, the first end of the bending portion 122 is connected to the second buckling portion 121, and an angle is provided between the bending portion 122 and the second buckling portion 121. The locking portion 123 is connected to the second end of the bending portion 122, and an angle is provided between the locking portion 123 and the bending portion 122, and the operating member 130 is used to push the locking portion 123.

[0090] The bending portion 122 is bent compared to the second buckling portion 121, the locking portion 123 is bent compared to the bending portion 122, and the operating member 130 is used to push the locking portion 123. By providing two sections of bending structures on the locking member 120, the position on the locking member 120 pushed by the operating member 130 is far away from the rotation center of the locking member 120, thereby increasing the lever arm.

[0091] When the installation space of the locking member 120 in the length direction is limited, the locking member 120 can be provided with two bending structures to increase the force arm on the pushed side of the locking member 120. This makes it easier for the user to press the locking member 120 through the operating member 130, which is conducive to improving the user's convenience in using the lock structure 100.

[0092] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an embodiment of the present invention, a cooking utensil is proposed, comprising: a cavity assembly 200, a door assembly 300 and a lock structure 100 in any of the above embodiments, the door assembly 300 is connected to the cavity assembly 200 in an opening and closing manner, the cavity assembly 200 or the door assembly 300 includes a portion to be installed 310, a limiting member 110 is arranged at one of the cavity assembly 200 and the door assembly 300, and a locking member 120 and an operating member 130 are arranged at the other of the cavity assembly 200 and the door assembly 300.

[0093] The cooking appliance includes a door body assembly 300 and a cavity assembly 200. The door body assembly 300 is connected to the cavity assembly 200 in an opening and closing manner. The limit member 110 and the locking member 120 need to be locked with each other. Therefore, the limit member 110 is assembled to one of the door body assembly 300 and the cavity assembly 200, and the locking member 120 is assembled to the other of the door body assembly 300 and the cavity assembly 200.

[0094] In this embodiment, the limiting member 110 is provided on the cavity assembly 200, and the locking member 120 is provided on the door assembly 300 for exemplary description. The limiting member 110 is provided on the door assembly 300 in the same manner.

[0095] The door assembly 300 can drive the locking member 120 to move. When the door assembly 300 closes the cavity assembly 200, when the locking member 120 moves to the first position, the locking member 120 is locked with the limiting member 110, and the limiting member 110 restricts the movement of the locking member 120. At this time, it is difficult for the user to pull the door assembly 300. The door assembly 300 and the cavity assembly 200 are in a locked state, and the user cannot open the cavity assembly 200 by pulling the door assembly 300. When the locking member 120 moves to the second position, the locking member 120 is separated from the limiting member 110, and the limiting member 110 no longer limits the locking member 120. At this time, the user can complete the door opening action.

[0096] The operating member 130 and the first elastic member 140 can drive the locking member 120 to rotate. When the user needs to perform the door opening operation, the operating member 130 can be pressed, and the operating member 130 can push the locking member 120, so that the locking member 120 can rotate from the first position to the second position. At this time, the first elastic member 140 undergoes elastic deformation, and the locking member 120 is separated from the limiting member 110, and the limiting member 110 will not interfere with the door opening process. When the user stops pressing the operating member 130, the first elastic member 140 can drive the locking member 120 to rotate and reset. At this time, the locking member 120 pushes the operating member 130, so that the operating member 130 moves from the pushing position to the waiting position for the user to press the operating member 130 next time.

[0097] Before opening the cavity assembly 200, the user needs to first perform an unlocking operation to release the limiting member 110 from limiting the locking member 120, and then open the cavity assembly 200. Opening the cavity assembly 200 requires two steps, which is conducive to improving the safety of the cooking appliance.

[0098] During the cooking process of the cooking appliance or after the cooking process is finished, the temperature of the food in the cooking cavity is high. At this time, if the user directly opens the door to take out the food, there is a risk of scalding. Therefore, the present invention cooperates with the above-mentioned limiter 110 and the door hook so that if the user wants to open the cavity assembly 200, he must unlock the cooking appliance before opening the cavity assembly 200. In this way, on the one hand, it can serve as a reminder to the user, and on the other hand, it can prevent children from accidentally opening the cavity assembly 200, thereby greatly improving the safety of the cooking appliance.

[0099] Therefore, the lock structure 100 proposed in the present invention cooperates with the limit member 110 and the locking member 120 to increase the unlocking difficulty of the lock structure 100, prevent users, especially children, from accidentally opening the cavity assembly 200, and improve the safety of cooking utensils using the lock structure 100.

[0100] In a possible application, the door assembly 300 includes a door body 340 and a door seal 350, wherein the door seal 350 is mounted on the door body 340. The cavity assembly 200 includes a main body 210 and a housing 220, wherein the housing 220 is covered on the main body 210.

[0101] like Fig.19 As shown, in the above embodiment, based on the position limiting member 110 being arranged on the cavity assembly 200, a through hole 320 is arranged on the door assembly 300, and a part of the operating member 130 passes through the through hole 320. The cooking utensil further includes: an annular member 330, which is connected to the outer wall of the door assembly 300 and is arranged around the through hole 320.

[0102] A through hole 320 is provided on the door assembly 300 . When the operating member 130 is located at the standby position, a portion of the operating member 130 passes through the through hole 320 and extends out of the door assembly 300 , so that the user can press the operating member 130 conveniently.

[0103] In order to disable the locking member 120, the operating member 130 needs to be rotated to the disabled position. By providing an annular member 330 on the circumference of the through hole 320, it is difficult for the user's hands to hold the operating member 130. That is, it is difficult for the user to rotate the operating member 130 only by hand, but it is necessary to use a workpiece to rotate the operating member 130, thereby increasing the difficulty of rotating the operating member 130 and preventing children from rotating the operating member 130 and disabling the locking member 120, thereby further improving the safety of the cooking appliance.

[0104] Combination Fig. 20 , Fig.21 and Fig. 22 As shown, in a possible embodiment, optionally, the portion to be installed 310 includes a limiting rib 311, and when the operating member 130 is in the failure position, the boss 160 in the lock structure 100 contacts the limiting rib 311 to limit the movement of the operating member 130 to the position to be operated.

[0105] The to-be-installed portion 310 refers to a portion of the structure on the door assembly 300 , and the locking member 120 can rotate relative to the to-be-installed portion 310 .

[0106] When the operating member 130 is located at the waiting position, the limiting portion 132 contacts the waiting installation portion 310 , that is, the limiting portion 132 contacts the inner wall of the door assembly 300 , to prevent the operating member 130 from being separated from the installation position.

[0107] A limiting rib 311 is provided on the inner wall of the door body assembly 300. When there is a need to fix the locking member 120 in the second position, the operating member 130 needs to be pressed to the pushing position first. At this time, the boss 160 and the limiting rib 311 are staggered. By rotating the operating member 130, the boss 160 is rotated to a position opposite to the limiting rib 311. The boss 160 and the limiting rib 311 are abutted against each other, and the limiting rib 311 limits the boss 160. At this time, the user stops pushing the operating member 130, and the operating member 130 will not move to the position to be operated. Therefore, the locking member 120 can be maintained in a position separated from the limiting member 110, that is, the locking member 120 is in an "invalid" state.

[0108] By disabling the locking member 120, the user no longer needs to press the operating member 130 when opening the cavity assembly 200, which makes it easier for the user to use the cooking utensil, improves the functional diversity of the cooking utensil, and meets the user's usage needs in different scenarios.

[0109] In a possible embodiment, the cooking appliance further includes: a rib 360 , which is disposed on the portion to be installed 310 , and is located below the limiting portion 132 , and is used to limit the pressing of the operating member 130 .
