Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0048] like Figure 1 , Figure 2 and Figure 12 As shown, according to an embodiment of the present invention, an interlocking assembly 100 is provided for locking or unlocking the door 202 and the front panel 201 of a cooking device.

[0049] The interlocking assembly 100 includes: an interlocking base 10, a door hook 20, a micro switch 40, and a rotating block 30.

[0050] The interlock seat 10 is fixedly connected to the front panel 201, and the interlock seat 10 is located on the side of the front panel 201 opposite to the door body 202. In this invention, the direction perpendicular to the front panel 201 is defined as the horizontal direction. The interlock seat 10 is an irregularly shaped frame structure. Along the direction perpendicular to the front panel 201, the interlock seat 10 is provided with multiple assembly structures at intervals to install the micro switch 40 and the rotating block 30 onto the interlock seat 10, and the interlock seat 10 is installed onto the front door panel. The interlock seat 10 has a horizontal length greater than its vertical length. The micro switch 40, rotating block 30, and door hook 20 are arranged in sequence in the horizontal direction, with the rotating block 30 positioned between the micro switch 40 and the door hook 20. This arrangement of the door hook 20, rotating block 30, micro switch 40, and interlock seat 10 in a direction perpendicular to the front panel 201 fully utilizes the horizontal space to reduce the vertical space occupied by the interlock assembly 100, thereby increasing the volume of the cavity and the ratio of the cavity volume to the overall volume.

[0051] Specifically, such as Figures 3 to 5 As shown, the interlock seat 10 includes a first assembly portion 11 located on the side of the interlock seat 10 near the front plate 201, a second assembly portion 12 located below the first assembly portion 11, and a third assembly portion 13 located on the side of the interlock seat 10 away from the front plate 201.

[0052] The first assembly part 11 is used to install the interlock seat 10 onto the front panel 201. The second assembly part 12 is disposed opposite to the door hook 20, and the second assembly part 12 is provided with a through hole 121 through which the door hook 20 passes. The third assembly part 13 is used to install the micro switch 40, and the first assembly part 11 and the third assembly part 13 are arranged and spaced apart along a direction perpendicular to the front panel 201, defining an assembly space 14 between the first assembly part 11 and the third assembly part 13, and the rotating block 30 is rotatably disposed in the assembly space 14. The third mounting part 71 is provided with a through hole 131 communicating with the assembly space 14, and the micro switch 40 is provided with a trigger button 43, which extends into the assembly space 14 through the through hole 131. The rotating block 30 includes a hook part 32 and an actuating part 33, the hook part 32 being located on the side of the rotating block 30 facing the door hook 20, and the actuating part 33 being located on the side of the rotating block 30 facing the micro switch 40. The door hook 20 is installed on the door body 202. The door hook 20 is located on the side of the door body 202 facing the front panel 201. The door hook 20 is provided with a lock hole 21. The lock hole 21 is located near the end of the door hook 20 facing the rotating block 30. The hook part 32 can cooperate with the lock hole 21 to realize the locking of the door hook 20 and the rotating block 30.

[0053] In detail, when the user pushes the door 202 to close or open, the door hook 20 passes through the through hole 121 and contacts the rotating block 30, pushing the rotating block 30 to rotate relative to the interlock seat 10, thereby enabling the rotating block 30 to switch between the locked position and the unlocked position.

[0054] like Figure 2 As shown, during the closing process of the door 202, after the door hook 20 passes through the through hole 121 and contacts the rotating block 30, it pushes the rotating block 30 to rotate relative to the base in the first direction. At this time, the door hook 20 moves horizontally, and the rotation direction of the rotating block 30 is perpendicular to the door hook 20, so that the hook part 32 rotates away from the lock hole 21 until the hook part 32 is pulled out from the lock hole 21, and the touch part 33 rotates away from the trigger button 43 until the rotating block 30 rotates to the locking position, the hook part 32 inserts into the lock hole 21 and completes the locking action, the touch part 33 abuts against the trigger button 43, the micro switch 40 is opened, and the circuit of the cooking device 200 is turned on.

[0055] like Figure 1 As shown, during the opening of the door 202, the door hook 20 is withdrawn outward through the through hole 121, and drives the rotating block 30 to rotate relative to the base in the second direction. At this time, the door hook 20 moves horizontally, and the rotation direction of the rotating block 30 is perpendicular to the door hook 20, so that the hook part 32 rotates towards the lock hole 21 until the hook part 32 is inserted into the lock hole 21, and the touch part 33 rotates towards the trigger button 43. When the rotating block 30 rotates to the unlock position, the hook part 32 is completely pulled out of the lock hole 21 to complete the unlocking action. The touch part 33 separates from the trigger button 43, the micro switch 40 is turned off, and the circuit of the cooking device 200 is in the off state.

[0056] In some embodiments of the present invention, such as Figure 6 As shown, the rotating block 30 includes a main body 31, a rotating connecting part 34, a hook part 32, and a triggering part 33.

[0057] Specifically, such as Figure 6 , Figure 10 As shown, the rotating connecting part 34 is located near the edge of the main body 31, the hook part 32 is located on the side of the main body 31 near the door 202, and the trigger part 33 is located on the side of the main body 31 near the micro switch 40. The hook part 32 forms the outline of the rotating block 30 near the door 202, and the trigger part 33 forms the outline of the rotating block 30 near the micro switch 40. The line connecting the rotating connecting part 34, the hook part 32, and the trigger part 33 forms a triangle, and the central angle between the hook part 32 and the trigger part 33 and the rotation axis of the rotating connecting part 34 is less than 180°, so that the entire outline of the rotating block 30 is within a fan-shaped area (e.g., ...). Figure 10 As shown in the figure, compared with the semi-circular rotating block 30, the rotating block 30 proposed in this invention greatly reduces the volume of the rotating block 30 itself, which is beneficial to reducing the overall space occupied by the interlocking assembly 100.

[0058] The central angle of the rotation axis from the hook part 32 and the trigger part 33 to the rotation connection part 34 can be set according to actual needs, such as 150°, 120°, 100°, 90°, 80°, 70°, 60°, etc.

[0059] In this embodiment, such as Figure 10 As shown, the central angle α of the rotation axis from the hook part 32 and the trigger part 33 to the rotation connection part 34 ranges from 80° to 100°.

[0060] In this embodiment, such as Figure 1 , Figure 2 and Figure 6As shown, the main body 31 is provided with a stop part 311, which can abut against the end of the door hook 20 facing the rotating block 30. During the closing of the door 202, the door hook 20 passes through the through hole 121, contacts the stop part 311, and pushes the rotating block 30 to rotate in the first direction. The stop part 311 is located on the side away from the door hook 20 relative to the hook part 32, and an opening groove 36 is formed between the stop part 311 and the hook part 32. Specifically, in the unlocked position, the opening of the opening groove 36 is set towards the door hook 20. During the closing of the door 202, the end of the door hook 20 facing the rotating block 30 extends into the opening groove 36 through the opening of the opening groove 36, and after abutting against the stop part 311, pushes the rotating block 30 to rotate in the first direction. The end of the door hook 20 facing the rotating block 30 slides towards the bottom of the opening groove 36 relative to the rotating block 30. During this process, the hook part 32 is inserted into the lock hole 21 to achieve locking. In this embodiment, the second assembly part 12 is also provided with a limiting part 122 on the side facing the rotating block 30. When the rotating block 30 is in the unlocked position, the hook part 32 abuts against the limiting part 122 on the side facing the door hook 20.

[0061] It should be noted that, in this embodiment, as Figure 2 As shown, in the unlocked position, the hook 32 abuts against the limiting part 122 on the side facing the door hook 20; the rotating block 30 rotates from the unlocked position to the locked position by a first angle β, and the trigger part 33 abuts against the trigger button 43.

[0062] like Figure 11 As shown, in detail, for ease of description, the left side, right side, top, and bottom are as follows: Figure 1 As indicated by the arrow, the space occupied by the first rotating block 30 is specifically the space from the rightmost edge contour of the hook portion 32 in the unlocked position to the leftmost edge contour of the trigger portion 33 in the locked position. Since the central angle α in this embodiment ranges from 80° to 100°, even after the rotating block 30 rotates by the first angle, neither the rightmost edge contour of the hook portion 32 in the unlocked position nor the leftmost edge contour of the trigger portion 33 in the locked position is higher than the top contour of the rotating block 30. Understandably, the rotating block 30 does not occupy the space above it during rotation. The rotating block 30 fully utilizes the horizontal space and greatly reduces the space occupied by the rotating block 30 in the vertical direction, thereby reducing the overall vertical space occupied by the interlocking assembly 100, increasing the cavity volume, and increasing the ratio of cavity volume to the overall machine volume. The first angle at which the rotating block 30 rotates from the unlocked position to the locked position can be determined by adjusting the size of the door hook 20 and the rotating block 30. In this embodiment, the range of the first angle β is 30°~40°, such as 35°, 36°, etc.

[0063] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the interlocking assembly 100 also includes an elastic member 50.

[0064] The main body 31 is provided with a hinge 35. One end of the elastic member 50 is rotatably connected to the hinge 35, and the other end is rotatably connected to the interlocking seat 10. The elastic member 50 is used to apply an elastic force to the rotating block 30 and to keep the rotating block 30 in a stable position in both the locked and unlocked positions. Specifically, during the closing of the door 202, the door hook pushes the rotating block 30 to the locked position, causing the actuating part 33 to engage with the trigger button 43. During this process, the elastic member 50 rotates by a first angle. At this time, the extension line of the line connecting the two ends of the positioning elastic member 50 passes through the rotation axis of the rotating connection part 34 and is away from the door hook. The elastic member 50 applies a force in the first direction to the rotating block 30, causing the rotating block 30 to continue to rotate forward. This generates a certain locking force between the hook part 32 and the lock hole 21 to lock the position of the door 202 and keep the door 202 in a closed state. When the door 202 is in the open state, the rotating block 30 is in the unlocked position, and the rotating block 30 abuts against the corresponding limiting part 122 on the interlock seat 10. The door hook separates from the rotating block 30. At this time, the extension line of the line connecting the two ends of the elastic member 50 passes through the rotation axis of the rotating connection part 34 and is close to the side of the door hook. At this time, the elastic member 50 is in a natural state or has a certain deformation, and applies a second-direction force to the rotating block 30 to keep the rotating block 30 in the unlocked position.

[0065] In this embodiment, such as Figure 6 and Figure 10 As shown, the hinge portion 35 is disposed near the edge of the main body portion 31. The hinge portion 35 is located between the actuating portion 33 and the hook portion 32, and the distance between the hinge portion 35 and the rotation axis is less than the distance between the actuating portion 33 and the rotation axis. This makes the hinge portion 35 located in a fan-shaped area with the rotation axis as the center and the distance between the actuating portion 33 and the rotation axis as the radius, thereby preventing the space occupied by the hinge portion 35 from exceeding the vertical space occupied by the rotating block 30 during rotation.

[0066] In one exemplary implementation, such as Figure 1 As shown, the elastic member 50 is a torsion spring. During the process of rotating the block 30 from the unlocked position to the locked position, the torsion spring is always in a compressed state. Thus, in the locked position, the torsion spring provides a torque in the first direction to the rotating block 30, so that a certain locking force is generated between the hook 32 and the lock hole 21; in the unlocked position, the torsion spring provides a torque in the second direction to the rotating block 30, keeping the rotating block 30 in the unlocked position.

[0067] In another exemplary embodiment, the elastic member is a tension spring (not shown in the figure). One end of the tension spring is hinged to the hinge portion, and the other end extends over the top of the rotating block and is hinged to the interlocking seat. During the rotation of the rotating block from the unlocked position to the locked position, the torsion spring remains stretched, thus providing tension to the rotating block. Therefore, in the locked position, the torsion spring provides tension in a first direction to the rotating block, generating a certain locking force between the hook and the lock hole; in the unlocked position, the torsion spring provides tension in a second direction to the rotating block, holding it in the unlocked position. In this embodiment, by providing a tension spring, the space occupied by the overall structure of the interlocking assembly in the vertical direction can be further reduced.

[0068] In some embodiments of the present invention, such as Figure 2 and Figure 7 As shown, the interlocking assembly 100 also includes a guide block 60.

[0069] like Figure 8 and Figure 9 And refer to Figure 3 and Figure 4 As shown, the guide block 60 is fixedly mounted on the second assembly part 12 of the interlocking seat 10. Specifically, the second assembly part 12 has snap-fit ​​holes 124 on both sides of the through hole 121. The end of the guide block 60 facing the rotating block 30 has a snap-fit ​​structure 62 corresponding to each snap-fit ​​hole 124. The guide block 60 is snapped and fixed by the snap-fit ​​structure 62 engaging with the snap-fit ​​hole 124 of the second assembly part 12. The guide block 60 between the two snap-fit ​​structures 62 also has a protrusion structure 63. The outline of the protrusion structure 63 matches the through hole 121. When the guide block 60 is snapped with the second assembly part 12, the protrusion structure 63 is inserted into the through hole 121 to achieve the positioning of the guide block 60. The guide block 60 also has a guide hole 61. The guide hole 61 extends through the two opposite sides of the guide hole 61 in a direction perpendicular to the door body 202, and the guide hole 61 forms an opening on the side of the protrusion structure 63 facing the rotating block 30. The inner wall surface of the guide hole 61 is configured as a guide surface 611 for guiding. When the door hook 20 passes through the guide hole 61, it cooperates with the rotating block 30 under the guiding action of the guide surface 611, so that the hook part 32 can be accurately inserted into the lock hole 21.

[0070] In this embodiment, the cross-section of the guide hole 61 is rectangular, the guide surface 611 is an inclined plane, and the area of ​​the cross-section of the guide hole 61 gradually decreases along the direction close to the rotating block 30.

[0071] In this embodiment, in order to avoid interference between the rotating block 30 and the guide block 60 when the rotating block 30 rotates, a relief groove 631 is also provided on the protruding structure 63 to avoid the rotating block 30.

[0072] In some embodiments of the present invention, such as Figure 2 and Figure 7As shown, the interlocking assembly 100 also includes a connector 70.

[0073] Specifically, the connector 70 includes a body portion fixedly connected to the front plate 201, which is welded to the front plate 201. The connector 70 also includes a mounting portion 71 connected to the body portion. The mounting portion 71 is specifically formed by bending it towards the interlock seat 10 using sheet metal processing. The mounting portion 71 has a mounting hole, and the interlock seat 10 has a slotted hole 111 at a position corresponding to the mounting hole. Bolts are passed through the mounting hole and the slotted hole 111 to fix the interlock seat 10 to the connector 70, thereby fixing the interlock seat 10 to the front plate 201. It should be noted that by providing the slotted hole 111, the position of the interlock seat 10 can be adjusted, preserving adjustment margins for misalignment caused by manufacturing and assembly errors.

[0074] The top of the connector 70 is also provided with a flip structure for limiting the position of the interlock assembly 100 in the vertical direction. The installation of the interlock seat 10 provides a vertical reference, which helps to improve assembly efficiency.

[0075] In some embodiments of the present invention, such as Figure 7 As shown, the micro switch 40 includes an energizing switch 41 and a detection switch 42.

[0076] The power switch 41 and the detection switch 42 are arranged side by side and are both mounted on the third mounting part 71. The trigger button 43 includes a first trigger button 431 that cooperates with the power switch 41 and a second trigger button 432 that cooperates with the detection switch 42. Both the first trigger button 431 and the second trigger button 432 extend toward the actuation part 33 through the through hole 131.

[0077] Specifically, both the power switch 41 and the detection switch 42 are connected to the control circuit of the cooking appliance 200. When the door 202 is closed, the trigger part 33 simultaneously triggers the first trigger button 431 and the second trigger button 432, turning on the power switch 41 and the detection switch 42. When the door 202 is open, the trigger part 33 simultaneously separates from the first trigger button 431 and the second trigger button 432, turning off the power switch 41 and the detection switch 42.

[0078] In this embodiment, the power switch 41 is used to control the on / off state of the control circuit, and the detection switch 42 is used to detect the on / off state of the power switch 41, and controls the on / off state of the control circuit of the cooking device 200 according to the on / off state of the power switch 41. The combined use of the detection switch 42 and the power switch 41 provides dual protection, preventing the power switch 41 from remaining in a conducting state while the door 202 is open. This avoids the situation where the cooking device 200 remains powered on when the door 202 is open, thus preventing potential safety hazards to the user, thereby improving the safety of the product and increasing its market competitiveness.

[0079] It should also be noted that by mounting both the detection switch 42 and the energizing switch 41 on the third mounting part 71, the detection switch 42 and the energizing switch 41 overlap in the horizontal direction, thereby reducing the vertical space occupied by the interlocking assembly 100.

[0080] In one exemplary implementation, such as Figure 6 As shown, the actuating part 33 is a hollow columnar structure extending along the horizontal plane, and the cross-section of the actuating part 33 is an irregular triangle. In order for the actuating part 33 to simultaneously actuate the first trigger button 431 and the second trigger button 432, the actuating part 33 is extended horizontally, the outer wall surface of the actuating part 33 is lengthened, and the contact area between the actuating part 33 and the trigger button 43 is increased.

[0081] According to embodiments of the present invention, such as Figure 12 and Figure 13 As shown, a cooking device 200 is also proposed. The cooking device 200 includes a front panel 201, a door 202, and an interlocking assembly 100.

[0082] Specifically, the door 202 is hinged to the front panel 201, allowing the door 202 to rotate relative to the front panel 201. The door 202 and the front panel 201 are unlocked or locked via an interlocking assembly 100. Because the interlocking assembly 100 occupies less space in the vertical direction, the ratio of the cavity volume to the overall volume of the cooking appliance 200 is larger, resulting in a more compact overall design.

[0083] In some embodiments of the present invention, the cooking device 200 further includes a body 210, with a front plate 201 fixedly mounted on the body 210. The body 210 has a cooking space inside for cooking food. A heat insulation plate 2101 is provided on the top of the body 210 to insulate heat from the cooking space. The micro switch 40 in the interlock assembly 100 is located outside the heat insulation plate 2101, thereby providing heat insulation protection for the internal components of the micro switch 40 and improving its service life.

[0084] In some embodiments of the present invention, the cooking device includes two interlocking components (not shown in the figure), which are arranged symmetrically on the left and right.

[0085] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
