[0030] Refer to the following Figures 1-3 Describe the cooking device 100 according to an embodiment of the present invention. The interlocking assembly 3 has a compact structure and a small volume, which can reduce the setting cost and improve the light weight of the cooking device 100.

[0031] As Figures 1-3 shown, a cooking device 100 according to an embodiment of the present invention includes: a device main body 1 and a door body 2.

[0032] The device main body 1 is provided with a cooking cavity, and the door body 2 is movably installed on the device main body to open or close the cooking cavity. Among them, the door body 2 is provided with a driving member 21 and a door hook 22, the device main body 1 is provided with an interlock bracket 31 and an interlock assembly 3, the interlock assembly 3 is installed on the interlock bracket 31, and the interlock assembly 3 includes a first linkage member 32, a second linkage member 33, a primary microswitch 34, a secondary microswitch 35 and a monitoring microswitch 36. The driving member 21 is adapted to push the first linkage member 32 to trigger the secondary microswitch 35, and the door hook 22 is adapted to push the second linkage member 33 to trigger the monitoring microswitch 36 and the primary microswitch 34 respectively.

[0033] Among them, the cooking device 100 can be set as a microwave oven, a microwave steam oven, etc., which can be used for thawing, fermenting, preheating and baking food, etc. The cooking device 100 is internally provided with a cooking cavity and an electrical appliance compartment. The electrical appliance compartment is used to place the components required to complete the above operations. A space for accommodating food is formed inside the cooking cavity. When in use, the user can put the food into the cooking cavity, and then perform operations such as thawing, fermenting, preheating and baking on the food to meet different needs of the user.

[0034] Specifically, the cooking device 100 is provided with a device main body 1 and a door body 2. A cooking cavity is formed inside the device main body 1. The cooking cavity is used to place food and perform corresponding processing on the food. And one side of the cooking cavity is open, forming a cooking cavity opening. The food is put into the cooking cavity through the cooking cavity opening. The door body 2 is movably installed on the device main body 1, and the door body 2 can be used to selectively close the cooking cavity. That is, when the user needs to take the food in the cooking cavity or put the food into the cooking cavity, the door body 2 can be driven away from the cooking cavity opening, so that the cooking cavity is opened. When the cooking device 100 is running or idle, the door body 2 can be used to close the cooking cavity to make the cooking cavity in a sealed state, ensuring the use safety of the cooking device 100 and the cleanliness of the cooking cavity.

[0035] Moreover, the device main body 1 is also provided with an interlock assembly 3. The interlock assembly 3 can be used as a system safety circuit switch for the door body 2 to access the cooking device 100. When the door body 2 is in the open state, the interlock assembly 3 is disconnected, and at this time, the cooking device 100 cannot work. When the door body 2 is in the closed state, the interlock assembly 3 is triggered, and at this time, the cooking device 100 can work normally. The device main body 1 is also provided with an interlock bracket 31, and the interlock assembly 3 is installed on the interlock bracket 31, that is, the interlock assembly 3 can be installed on the device main body 1 through the interlock bracket 31, and thus can be fixed relative to the device main body 1. That is to say, in the present utility model, the first linkage member 32, the second linkage member 33, the primary microswitch 34, the secondary microswitch 35, and the monitoring microswitch 36 of the interlock assembly 3 are all integrally arranged on the same interlock bracket 31, realizing the integrated arrangement of multiple structural members, that is, the three microswitches are centrally arranged, and there will be no problem that the interlock assembly 3 occupies too much installation space inside the device main body 1 due to the scattered installation of the microswitches. The compactness of the interlock assembly 3 can be improved, the volume of the interlock assembly 3 can be reduced, and the number of interlock brackets 31 can be reduced. Furthermore, the light weight of the cooking device 100 can be improved, and the materials required for manufacturing the cooking device 100 can be reduced, thereby reducing the setting cost.

[0036] Further, the door body 2 is provided with a driving member 21 and a door hook 22. The driving member 21 and the door hook 22 are both spaced apart along the edge of the door body 2 and are arranged towards the device main body 1. The interlock assembly 3 is provided with a first linkage member 32, a second linkage member 33, a primary microswitch 34, a secondary microswitch 35, and a monitoring microswitch 36. During the process of the door body 2 closing the cooking cavity, the driving member 21 can push the first linkage member 32, thereby causing the first linkage member 32 to trigger the secondary microswitch 35, and the door hook 22 can push the second linkage member 33, so that the second linkage member 33 can respectively trigger the monitoring microswitch 36 and the primary microswitch 34.

[0037] Among them, the primary microswitch 34 and the secondary microswitch 35 can respectively trigger different circuit conditions when the door body 2 is opened and closed, thereby affecting the connection and disconnection of the power supply of the cooking device 100. When any one of the primary microswitch 34 and the secondary microswitch 35 shows that the door body 2 is not normally closed or not tightly closed, the cooking device 100 cannot operate normally, improving the use safety of the cooking device 100. The interlock assembly 3 is also provided with a monitoring microswitch 36. When the primary microswitch 34 and the secondary microswitch 35 fail and cause the line to be short-circuited normally, the monitoring microswitch 36 can disconnect the power supply of the cooking device 100, thereby further ensuring the use safety of the cooking device 100 and improving the use experience.

[0038] According to the cooking device 100 of the embodiment of the present utility model, by integrally mounting the interlock assembly 3 on the interlock bracket 31, the structure of the interlock assembly 3 is compact, the volume of the interlock assembly 3 can be reduced, thereby the light weight of the cooking device 100 can be improved, and the materials required for manufacturing the cooking device 100 can be reduced, thereby the installation cost can be lowered, and the use effect is better and the applicable range is wider.

[0039] In some embodiments, the first linkage 32 is arranged to be rotatable relative to the device main body 1, and the driving member 21 is arranged to push the first linkage 32 to rotate in the first direction to trigger the secondary microswitch 35 during the process of closing the cooking cavity by the door body 2.

[0040] Specifically, the interlock assembly 3 is mounted on the interlock bracket 31, and thus can be fixed to the device main body 1. The interlock assembly 3 is provided with a first linkage 32. The interlock bracket 31 is provided with a mounting post, and the first linkage 32 is rotatably mounted on the interlock bracket 31 through the mounting post. Thus, when the first linkage 32 rotates relative to the interlock bracket 31, the secondary microswitch 35 can be triggered. The secondary microswitch 35 is in a normally open state. When the first linkage 32 triggers the secondary microswitch 35, the secondary microswitch 35 switches from the normally open state to the closed state, and thus the circuit can be switched on.

[0041] Further, as Figures 2-3 shown, the first linkage 32 is provided with a connected connecting portion 321 and a pushing portion 322. The connecting portion 321 is rotatably connected to the interlock bracket 31 through the mounting post, and the pushing portion 322 is connected to the side of the connecting portion 321 close to the secondary microswitch 35. During the process of closing the cooking cavity by the door body 2, the driving member 21 can move towards the first linkage 32, and thus can push the connecting portion 321 to rotate relative to the interlock bracket 31 in the first direction to drive the pushing portion 322 to trigger the secondary microswitch 35, and thus the circuit can be switched on, ensuring the operation reliability of the cooking device 100 and improving the use safety of the cooking device 100.

[0042] In some embodiments, the interlock assembly 3 further includes a first elastic reset member. The first elastic reset member is connected to the first linkage 32 and is arranged to push the first linkage 32 to rotate in the second direction to separate from the secondary microswitch 35 during the process of opening the cooking cavity by the door body 2. The first direction is opposite to the second direction.

[0043] Specifically, the interlock assembly 3 is further provided with a first elastic reset member, which can be set as a spring or the like, and the first elastic reset member can be connected to the connecting portion 321 of the first linkage member 32. The secondary microswitch 35 is provided with a first contact 351, and the first contact 351 protrudes from the secondary microswitch 35 and is movable relative to the secondary microswitch 35. During the process of the door body 2 closing the cooking cavity, the driving member 21 can move towards the first linkage member 32, and then can push the connecting portion 321 to rotate relative to the interlock bracket 31 in the first direction, so as to drive the pushing portion 322 to push the first contact 351, and then the secondary microswitch 35 is switched from the normally open state to the closed state to connect the circuit. At this time, the first elastic reset member is compressed.

[0044] And when the door body 2 opens the cooking cavity, the driving member 21 leaves the connecting portion 321, and then the connecting portion 321 rotates in the second direction under the elastic force of the first elastic reset member, so as to drive the pushing portion 322 to leave the first contact 351, and then the secondary microswitch 35 is switched from the closed state to the normally open state to disconnect the circuit. The first direction is opposite to the second direction, so that the first linkage member 32 makes a reciprocating motion in a certain area, and then the space required for the movement of the first linkage member 32 can be reduced, the volume of the interlock assembly 3 can be reduced, and the weight reduction of the cooking device 100 can be improved.

[0045] Wherein, one of the first direction and the second direction can be set as the clockwise direction, and the other can be set as the counterclockwise direction, that is, the first direction can be set as the clockwise direction and the second direction can be set as the counterclockwise direction, or the first direction can be set as the counterclockwise direction and the second direction can be set as the clockwise direction.

[0046] In some embodiments, the second linkage member 33 is set to be rotatable relative to the device main body 1, and the door hook 22 is set to push the second linkage member 33 to rotate in the first direction to sequentially trigger the monitoring microswitch 36 and the primary microswitch 34 during the process of the door body 2 closing the cooking cavity.

[0047] Specifically, the interlock assembly 3 is provided with a second linkage member 33, the interlock bracket 31 is provided with a mounting post, and the second linkage member 33 is rotatably mounted on the interlock bracket 31 through the mounting post. When the second linkage member 33 rotates relative to the interlock bracket 31, it can trigger the monitoring microswitch 36 and the primary microswitch 34. The primary microswitch 34 is in the normally open state. When the second linkage member 33 triggers the primary microswitch 34, the primary microswitch 34 is switched from the normally open state to the closed state. The monitoring microswitch 36 is in the normally closed state. When the second linkage member 33 triggers the monitoring microswitch 36, the monitoring microswitch 36 is switched from the normally closed state to the open state, and then the circuit can be connected.

[0048] Further, as Figures 2-3As shown, the second linkage 33 can be set as a cam, and a first convex portion 332 and a second convex portion 333 protruding radially outward are provided on the circumference of the second linkage 33. The primary microswitch 34 is provided with a second contact 341. The second contact 341 protrudes from the primary microswitch 34 and is movable relative to the primary microswitch 34. The monitoring microswitch 36 is provided with a third contact 361. The third contact 361 protrudes from the monitoring microswitch 36 and is movable relative to the monitoring microswitch 36. During the process of the door body 2 closing the cooking cavity, the door hook 22 can move towards the second linkage 33, and then can push the second linkage 33 to rotate relative to the interlock bracket 31 in the first direction, so that the first convex portion 332 triggers the second contact 341 and the second convex portion 333 triggers the third contact 361, thereby closing the circuit, ensuring the operating reliability of the cooking device 100, and improving the use safety of the cooking device 100.

[0049] In some embodiments, the interlock assembly 3 further includes a second elastic reset member 37. The second elastic reset member 37 is connected to the second linkage 33. The second elastic reset member 37 is configured to push the second linkage 33 to rotate in the second direction during the process of the door body 2 opening the cooking cavity to separate from the monitoring microswitch 36 and the primary microswitch 34. The first direction is opposite to the second direction.

[0050] Specifically, as Figures 2-3 shown, the interlock assembly 3 is further provided with a second elastic reset member 37. The second elastic reset member 37 can be set as a spring or the like. One end of the second elastic reset member 37 is rotatably connected to the second linkage 33, and the other end is rotatably connected to the interlock bracket 31. During the process of the door body 2 closing the cooking cavity, the door hook 22 can move towards the second linkage 33, and then can push the second linkage 33 to rotate relative to the interlock bracket 31 in the first direction, so that the first convex portion 332 triggers the second contact 341 and the second convex portion 333 triggers the third contact 361, thereby closing the circuit. At this time, the second elastic reset member 37 is compressed.

[0051] Furthermore, during the process of the door body 2 opening the cooking cavity, the door hook 22 leaves the second linkage 33, and then the second linkage 33 rotates in the second direction under the elastic force of the second elastic reset member 37, so that the first convex portion 332 leaves the second contact 341 and the second convex portion 333 leaves the third contact 361. As a result, the primary microswitch 34 switches from the closed state to the normally open state, and the monitoring microswitch 36 switches from the off state to the normally closed state. The first direction is opposite to the second direction, causing the second linkage 33 to make a reciprocating motion in a certain area, thereby reducing the space required for the movement of the second linkage 33, shrinking the volume of the interlock assembly 3, and improving the light weight of the cooking device 100.

[0052] One of the first direction and the second direction can be set as the clockwise direction, and the other can be set as the counterclockwise direction. That is, the first direction can be set as the clockwise direction and the second direction as the counterclockwise direction, or the first direction can be set as the counterclockwise direction and the second direction as the clockwise direction.

[0053] In some embodiments, the second linkage 33 is provided with a pushing groove 331. The pushing groove 331 is arranged to open radially outward along the rotation axis of the second linkage 33. At least part of the door hook 22 is adapted to extend into the pushing groove 331 to push the second linkage 33 to rotate.

[0054] Specifically, during the process of the door body 2 closing the cooking cavity, the door hook 22 can push the second linkage 33 to rotate in the first direction, so that the second linkage 33 can sequentially trigger the monitoring microswitch 36 and the primary microswitch 34, and as Figures 2-3 shown, the second linkage 33 is provided with a pushing groove 331. The pushing groove 331 can be arranged to open radially outward along the rotation axis of the second linkage 33. That is, when the door hook 22 pushes the second linkage 33, part of the door hook 22 can extend into the pushing groove 331, and then the second linkage 33 can be pushed to rotate in the first direction by pushing the pushing groove 331. The groove body of the pushing groove 331 is an arc surface, so that the door hook 22 moves more smoothly in the pushing groove 331, ensuring the smooth rotation of the second linkage 33.

[0055] Furthermore, as Figure 1 shown, the door hook 22 is also provided with a pushing hole 221. The pushing hole 221 can be set as a through hole such as a circular or rectangular shape. When the door hook 22 pushes the second linkage 33 to rotate in the first direction, part of the second linkage 33 can extend into the pushing hole 221. And during the process of the door body 2 opening the cooking cavity, the pushing hole 221 can also drive the second linkage 33 to rotate in the second direction, thereby avoiding the slippage between the door hook 22 and the second linkage 33 and ensuring the reliability of the movement between the door hook 22 and the second linkage 33.

[0056] In some embodiments, the length of the door hook 22 protruding from the door body 2 towards the device main body 1 is greater than the length of the driving member 21 protruding from the door body 2 towards the device main body 1; wherein, the interlock assembly 3 is arranged such that during the process of the door body 2 closing towards the device main body 1, the second linkage 33 first triggers the monitoring microswitch 36, then the first linkage 32 triggers the secondary microswitch 35, and finally the second linkage 33 triggers the primary microswitch 34.

[0057] Specifically, as Figure 1As shown, an active member 21 and a door hook 22 are provided at intervals on the edge of the door body 2. During the process of the door body 2 closing the cooking cavity, the active member 21 can push the first linkage member 32 to rotate in the first direction, so that the first linkage member 32 triggers the secondary microswitch 35. The door hook 22 can push the second linkage member 33 to rotate in the first direction, so that the second linkage member 33 triggers the monitoring microswitch 36 and the primary microswitch 34 in sequence. And the length of the door hook 22 protruding towards the device main body 1 relative to the door body 2 is greater than the length of the active member 21 protruding towards the device main body 1 relative to the door body 2. That is, during the process of the door body 2 closing the cooking cavity, the door hook 22 first pushes the second linkage member 33 to rotate in the first direction, and then the active member 21 pushes the first linkage member 32 to rotate in the first direction.

[0058] Furthermore, during the process of the door body 2 closing the cooking cavity, the door hook 22 can first push the second linkage member 33 to rotate in the first direction, so that the second linkage member 33 can first trigger the monitoring microswitch 36. And as the door body 2 moves, the active member 21 pushes the first linkage member 32 to trigger the secondary microswitch 35. Finally, as the second linkage member 33 continues to rotate, the second linkage member 33 can trigger the primary microswitch 34. That is, the monitoring microswitch 36, the secondary microswitch 35 and the primary microswitch 34 can be triggered in sequence, and finally the power supply of the cooking device 100 is connected to ensure the use safety of the cooking device 100.

[0059] In some embodiments, the primary microswitch 34 and the secondary microswitch 35 are set as normally open switches, and the monitoring microswitch 36 is set as a normally closed switch.

[0060] Specifically, during the process of the door body 2 closing the cooking cavity, the first linkage member 32 can trigger the secondary microswitch 35, and the second linkage member 33 can trigger the monitoring microswitch 36 and the primary microswitch 34 in sequence. And the second linkage member 33 first triggers the monitoring microswitch 36, then the first linkage member 32 triggers the secondary microswitch 35, and finally the second linkage member 33 triggers the primary microswitch 34. The monitoring microswitch 36 is set as a normally closed switch. That is, when the second linkage member 33 triggers the monitoring microswitch 36, the monitoring microswitch 36 switches from the normally closed state to the open state. And the primary microswitch 34 and the secondary microswitch 35 are both set as normally open switches. That is, when the second linkage member 33 triggers the monitoring microswitch 36, the primary microswitch 34 switches from the normally open state to the closed state. When the first linkage member 32 triggers the secondary microswitch 35, the secondary microswitch 35 switches from the normally open state to the closed state.

[0061] Further, when any one of the primary microswitch 34 and the secondary microswitch 35 is in the normally open state, it indicates that the door body 2 is not properly closed or not tightly closed. At this time, the cooking device 100 cannot operate normally, improving the safety of using the cooking device 100. And when the primary microswitch 34 and the secondary microswitch 35 fail and cause the circuit to be short-circuited normally, the monitoring microswitch is in the off state, and then the power supply of the cooking device 100 can be disconnected, further ensuring the safety of using the cooking device 100 and improving the user experience.

[0062] In some embodiments, the first linkage 32 and the second linkage 33 are respectively rotatably mounted on the interlock bracket 31, and the primary microswitch 34, the secondary microswitch 35 and the monitoring microswitch 36 are respectively fixedly mounted on the interlock bracket 31.

[0063] Specifically, as Figures 2-3 shown, the interlock assembly 3 is mounted on the device main body 1 through the interlock bracket 31, and the first linkage 32 can be rotatably mounted on the interlock bracket 31 through the mounting post, so that the driving member 21 can push the first linkage 32 to rotate in the first direction, and the secondary microswitch 35 is fixedly mounted on the interlock bracket 31. After the first linkage 32 rotates, it can trigger the secondary microswitch 35, thereby ensuring the operation reliability.

[0064] Further, the second linkage 33 can be rotatably mounted on the interlock bracket 31 through the mounting post, so that the door hook 22 can push the second linkage 33 to rotate in the first direction, and the primary microswitch 34 and the monitoring microswitch 36 are fixedly mounted on the interlock bracket 31 at intervals, so that after the second linkage 33 rotates, it can trigger the monitoring microswitch 36 and the primary microswitch 34 in sequence, thereby ensuring the operation reliability.

[0065] In some embodiments, the driving member 21 and the door hook 22 are arranged in parallel and spaced apart in the up-down direction. The first linkage 32 and the secondary microswitch 35 are located in the upper region of the interlock bracket 31, and the second linkage 33 and the primary microswitch 34 and the monitoring microswitch 36 are located in the middle and lower regions of the interlock bracket 31.

[0066] Specifically, as Figure 1 shown, the driving member 21 and the door hook 22 which are spaced apart in the up-down direction are arranged at the edge of the door body 2. Both the driving member 21 and the door hook 22 protrude relative to the door body 2 towards the device main body 1. The interlock bracket 31 is provided with a first through hole and a second through hole. During the process of the door body 2 closing the cooking cavity, the driving member 21 can pass through the first through hole, thereby pushing the first linkage 32, and the door hook 22 can pass through the second through hole, thereby pushing the second linkage 33.

[0067] Moreover, the first via hole, the first linkage 32, and the primary microswitch 34 are located in the upper region of the interlock bracket 31, facilitating the driving member 21 to push the first linkage 32 to trigger the secondary microswitch 35. Also, the second via hole, the second linkage 33, the primary microswitch 34, and the monitoring microswitch 36 are all located in the middle and lower regions of the interlock bracket 31, facilitating the door hook 22 to push the second linkage 33 to trigger the monitoring microswitch 36 and the primary microswitch 34. This can make the interlock assembly 3 structurally compact, save installation space, and reduce installation costs.

[0068] In some embodiments, the distance between the driving member 21 and the door hook 22 in the vertical direction is set as L1, and it satisfies: 20 mm ≤ L1 ≤ 21 mm, and / or, the distance between the rotation axes of the first linkage 32 and the second linkage 33 in the vertical direction is set as L2, and it satisfies: 22 mm ≤ L2 ≤ 23 mm, and / or, the distance between the rotation axes of the first linkage 32 and the second linkage 33 in the horizontal direction is set as L3, and it satisfies: 1 mm ≤ L3 ≤ 2 mm.

[0069] Specifically, the driving member 21 and the door hook 22 are arranged at intervals in the vertical direction on the edge of the door body 2. Both the driving member 21 and the door hook 22 protrude relative to the door body 2 towards the equipment main body 1. The distance between the driving member 21 and the door hook 22 in the vertical direction is set as L1, and it satisfies: 20 mm ≤ L1 ≤ 21 mm. That is, the distance L1 between the driving member 21 and the door hook 22 in the vertical direction can be set to 20 mm, 20.3 mm, or 21 mm, etc. In this embodiment, the distance L1 between the driving member 21 and the door hook 22 in the vertical direction is set to 20.3 mm.

[0070] Furthermore, the first linkage 32 can be rotatably mounted on the interlock bracket 31 through a mounting post, and the second linkage 33 can also be rotatably mounted on the interlock bracket 31 through a mounting post. The distance between the rotation axes of the first linkage 32 and the second linkage 33 in the vertical direction is set as L2, and it satisfies: 22 mm ≤ L2 ≤ 23 mm. That is, the distance L2 between the rotation axes of the first linkage 32 and the second linkage 33 in the vertical direction can be set to 22 mm, 22.3 mm, or 23 mm, etc. In this embodiment, the distance L2 between the rotation axes of the first linkage 32 and the second linkage 33 in the vertical direction is set to 22.3 mm.

[0071] In addition, the distance between the rotation axis of the first linkage member 32 and the rotation axis of the second linkage member 33 in the horizontal direction is set as L3, and it satisfies: 1 mm ≤ L3 ≤ 2 mm. That is, the distance L3 between the rotation axis of the first linkage member 32 and the rotation axis of the second linkage member 33 in the horizontal direction can be set to 1 mm, 1.3 mm, 2 mm, etc. In this embodiment, the distance L3 between the rotation axis of the first linkage member 32 and the rotation axis of the second linkage member 33 in the horizontal direction is set to 1.3 mm.

[0072] Set the positions of the driving member 21, the door hook 22, the first linkage member 32 and the second linkage member 33 to satisfy the above dimensions, which can ensure the operation reliability of the cooking device 100 while improving the compactness between the components of the cooking device 100, improving the light weight of the cooking device 100. And in actual setting, the distance between the rotation axis of the second linkage member 33 and the rightmost side of the interlock bracket 31 is set as L4, and the distance L4 between the rotation axis of the second linkage member 33 and the rightmost side of the interlock bracket 31 can be set to 8.8 mm. The distance between the driving member 21 and the uppermost side of the interlock bracket 31 is set as L5, and the distance L5 between the driving member 21 and the uppermost side of the interlock bracket 31 can be set to 3.4 mm.
