Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a cooking body and a microwave cooking appliance. Background Technology

[0002] Current microwave oven door interlock mechanisms are not waterproof. However, since most microwave ovens have side-opening doors, the opening for the door interlock mechanism is also on the side, thus posing no risk of water ingress. However, in microwave rice cookers and other top-opening appliances, the door interlock mechanism is located on the cooker body, with the corresponding opening facing upwards. When the lid is opened, water droplets on the lid can easily drip into the door interlock mechanism through the opening, posing a significant risk of water ingress and potentially damaging the electronic components inside the door interlock mechanism. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a cooking body for use in a microwave cooking appliance. The microwave cooking appliance includes a cover that is closable over the cooking body. The cooking body includes: an outer shell with a mounting cavity and a clearance opening communicating with the mounting cavity; a door interlocking mechanism including an interlocking bracket and an interlocking drive assembly, both disposed within the mounting cavity; the interlocking bracket having a groove structure communicating with the clearance opening; the interlocking drive assembly being disposed within the groove structure and at least partially located within the clearance opening; a drain outlet being provided on the groove sidewall of the groove structure and communicating with the clearance opening; and a micro switch assembly disposed within the interlocking bracket and outside the groove structure; the interlocking drive assembly correspondingly positioned to trigger the micro switch assembly.

[0005] In one embodiment, the drain outlet is located on the groove structure near the bottom, and the interlocking drive assembly is provided with a flow channel, which is connected to the clearance port and the drain outlet respectively. In the water flow direction, the flow channel is located between the clearance port and the drain outlet.

[0006] In one embodiment, the drainage channel includes a water receiving section and a drainage section, the water receiving section being connected to the clearance port, and the interlocking drive assembly being partially spaced apart from the interlocking bracket to be configured as the drainage section, the drainage section being connected to the water receiving section and the drain port.

[0007] In one embodiment, the interlocking drive assembly has a bent drainage section extending from the relief port to the drain port at the location of the drainage section, and the cavity of the drainage section is connected to the water receiving section and the drain port respectively.

[0008] In one embodiment, the interlocking drive assembly has a protruding water-blocking part, which is located between the flow channel and the micro switch assembly.

[0009] In one embodiment, the groove structure includes a first groove and a second groove; the interlocking drive assembly includes a first drive member and a second drive member; the first drive member is movably connected to the first groove, and the second drive member is movably connected to the second groove; the first drive member and the second drive member respectively trigger the micro switch assembly; the clearance port includes a first opening and a second opening; the first drive member is at least partially located in the first opening, and the second drive member is at least partially located in the second opening; the drain outlet extends along the arrangement direction of the first drive member and the second drive member, and passes through the first groove and the second groove; the drain outlet communicates with the first opening and the second opening.

[0010] In one embodiment, the micro switch assembly includes a first micro switch, a second micro switch, and a third micro switch. The first micro switch, the second micro switch, and the third micro switch are all connected to the interlocking bracket and located outside the groove structure. The first micro switch and the third micro switch are respectively configured to correspond to the first driving member, and the second micro switch is configured to correspond to the second driving member.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Current microwave oven door interlock mechanisms are not waterproof. However, since most microwave ovens have side-opening doors, the opening for the door interlock mechanism is also on the side, thus posing no risk of water ingress. However, in microwave rice cookers and other top-opening appliances, the door interlock mechanism is located on the cooker body, with the corresponding opening facing upwards. When the lid is opened, water droplets on the lid can easily drip into the door interlock mechanism through the opening, posing a significant risk of water ingress and potentially damaging the electronic components inside the door interlock mechanism.

[0037] In view of this, the existing microwave cooking appliances with top-opening lids have door interlocking mechanisms with openings facing the top, resulting in a high risk of water ingress and easy damage to electronic components. This utility model proposes a cooking body 10 and a microwave cooking appliance 100 to improve the problem of high water ingress risk in the door interlocking mechanism.

[0038] The specific structures of the cooking body 10 and the microwave cooking appliance 100 of this utility model will be described below:

[0039] Please refer to Figures 1 to 13This utility model proposes a cooking body 10, applied to a microwave cooking appliance 100. The microwave cooking appliance 100 includes a cover 20, which is closable and covers the cooking body 10. The cooking body 10 includes: a shell 11, which has a mounting cavity 111 and a clearance opening 112 communicating with the mounting cavity 111; and a door interlocking mechanism 12, which includes an interlocking bracket 121 and an interlocking drive assembly 122, which are disposed in the mounting cavity 111. Within the interlocking bracket 121, a groove structure 1211 is provided, which communicates with the clearance opening 112. The interlocking drive assembly 122 is disposed within the groove structure 1211 and is at least partially located within the clearance opening 112. A drain outlet 1211A is provided on the groove sidewall of the groove structure 1211, which communicates with the clearance opening 112. A micro switch assembly 13 is also provided within the interlocking bracket 121 and located outside the groove structure 1211. The interlocking drive assembly 122 is correspondingly disposed with respect to the micro switch assembly 13 and is used to trigger the micro switch assembly 13.

[0040] Specifically, the cooking body 10 includes a housing 11, a door interlock mechanism 12, and a micro switch assembly 13. The housing 11 is used to install and protect the internal components, while the door interlock mechanism 12 and the micro switch assembly 13 are used to control the operating status of the microwave cooking appliance 100 under specific conditions to prevent microwave leakage, protect the user from microwave radiation damage, and ensure operational safety.

[0041] The door interlocking mechanism 12 includes an interlocking bracket 121 and an interlocking drive assembly 122. The interlocking bracket 121 is used to mount the interlocking drive assembly 122 and the micro switch assembly 13, such as... Figure 8 The interlocking drive assembly 122 and the micro switch assembly 13 are arranged correspondingly. When the door interlocking mechanism 12 is running, the interlocking drive assembly 122 is used to trigger the micro switch assembly 13. A groove structure 1211 is provided on the interlocking bracket 121. The interlocking drive assembly 122 is installed in the groove structure 1211, and a drain port 1211A is opened on the groove side wall of the groove structure 1211. When water enters from the relief port 112, it will flow along the interlocking drive assembly 122 to the groove structure 1211, or directly into the groove structure 1211. The micro switch assembly 13 is located outside the groove structure 1211, and the water that enters can flow out from the drain port 1211A of the groove structure 1211 without interfering with the micro switch assembly 13.

[0042] By opening a drain port 1211A on the side wall of the groove structure 1211 of the interlock bracket 121, the water entering the door interlock mechanism 12 can be discharged in time, without interfering with the micro switch assembly 13 or accumulating inside, thus reducing the risk of water damaging the internal electronic components.

[0043] The micro switch assembly 13 is designed to be installed outside the groove structure 1211. Even if a small amount of water enters and flows into the groove structure 1211 through the clearance port 112, this water will first flow into the groove structure 1211 and be discharged through the drain port 1211A on the side wall of the groove, without directly contacting the micro switch assembly 13. This ensures the normal operation of the door interlock function, guarantees the safety and reliability of the equipment, and reduces the failure rate caused by accidental water ingress. This not only extends the service life of the product but also improves the user experience.

[0044] The shape of the drain outlet 1211A can be set to rectangular for rapid drainage; it can also be set to strip shape to provide a continuous drainage path to meet longer drainage needs; or it can be set to a multi-hole type, consisting of multiple small holes, which can provide multiple drainage paths and increase the flexibility and reliability of drainage.

[0045] like Figure 7 and Figure 11 The drain outlet 1211A is located near the bottom of the groove structure 1211, so that the water entering the groove can flow naturally to the lowest point and use gravity to ensure that the water can be discharged quickly.

[0046] The interlocking drive assembly 122 is movably disposed within the groove structure 1211, and can be either rotatably connected or slidably connected. The groove structure 1211 communicates with the relief port 112, allowing water droplets to enter through the relief port 112 and flow directly out along the groove structure 1211, exiting towards the bottom of the housing 11 without interfering with the micro switch assembly 13. Simultaneously, an opening is provided on the side wall of the groove structure 1211 between the interlocking drive assembly 122 and the micro switch assembly 13. When the interlocking drive assembly 122 is driven, it triggers the micro switch assembly 13.

[0047] This utility model's technical solution involves placing the interlocking drive assembly 122 inside the groove structure 1211 and the micro switch assembly 13 outside the groove structure 1211. A drain outlet 1211A is provided on the side wall of the groove structure 1211. When water enters from the relief port 112, it will directly enter the groove structure 1211 or flow along the interlocking drive assembly 122 to the groove structure 1211 and be discharged through the drain outlet 1211A of the groove structure 1211, preventing it from flowing to the micro switch assembly 13 and causing damage to it. The water flow will be guided along the surface of the first part that comes into contact with the water (i.e., the interlocking drive assembly 122). Therefore, the groove structure 1211 is designed to guide and collect water that may enter the equipment, isolate it from the micro switch assembly 13, reduce the risk of water ingress, and discharge it through the drain outlet 1211A to reduce accumulation, thereby protecting the micro switch assembly 13 from the influence of water.

[0048] In an embodiment of this utility model, the interlocking drive assembly 122 is provided with a flow channel 1221, which is connected to the clearance port 112 and the drain port 1211A respectively. In the water flow direction, the flow channel 1221 is located between the clearance port 112 and the drain port 1211A.

[0049] In detail, a flow channel 1221 is also provided on the interlock drive assembly 122. The flow channel 1221 is connected to the relief port 112. The flow channel 1221 provides a clear water flow path, allowing water to flow along a predetermined path. When water enters from the relief port 112, it flows to the interlock drive assembly 122 and can be directly discharged through the flow channel 1221 to the drain port 1211A. This ensures that the water entering the door interlock mechanism 12 can be discharged quickly and smoothly, reducing the water retention time inside and preventing water from accumulating around the interlock drive assembly 122.

[0050] With the design of the drainage channel 1221, moisture is quickly guided to the drain outlet 1211A and discharged, which helps to keep the interlock drive assembly 122 dry, extend its service life, ensure that the micro switch assembly 13 and other key electronic components are not affected by moisture, reduce their risk of water ingress, and maintain normal operation.

[0051] In an embodiment of this utility model, the diversion channel 1221 includes a water receiving section 1221A and a diversion section 1221B. The water receiving section 1221A is connected to the relief port 112. The interlocking drive assembly 122 is partially spaced from the interlocking bracket 121 and is configured as the diversion section 1221B. The diversion section 1221B is connected to the water receiving section 1221A and the drain port 1211A.

[0052] It is worth noting that a water receiving section 1221A is formed on the interlocking drive assembly 122. The water receiving section 1221A is connected to the relief port 112, allowing water to flow orderly from the relief port 112 into the water receiving section 1221A and be guided to the diversion section 1221B. From there, the water can be directly directed to the drain port 1211A for discharge. This design can effectively control the water flow direction and improve drainage efficiency.

[0053] The drainage section 1221B is partially spaced from the interlocking bracket 121 by the interlocking drive assembly 122, which makes the drainage section 1221B closer to the interlocking bracket 121 and can reduce the risk of water leakage. Since the design of the drainage section 1221B reduces the risk of water leakage, it can better protect the micro switch assembly 13 from moisture, and extend the service life and reliability of the equipment.

[0054] Meanwhile, the drainage section 1221B is formed by the gap between the interlocking drive assembly 122 and the interlocking bracket 121, without the need for additional structural components, reducing the number of parts, making the whole design more integrated, saving space, and improving the overall structural compactness and reliability.

[0055] In an embodiment of this utility model, the interlocking drive assembly 122 is provided with a bent drainage section 1222 extending from the relief port 112 to the drain port 1211A at the position located at the drainage section 1221B. The cavity of the drainage section 1222 is connected to the water receiving section 1221A and the drain port 1211A respectively.

[0056] It is worth noting that, such as Figure 7 A drainage section 1222 is provided on the interlock drive assembly 122 near the interlock bracket 121. The drainage section 1222 is located between the water receiving section 1221A and the drain outlet 1211A. The drainage section 1222 and the interlock drive assembly 122 cooperate to form a cavity. The cavity of the drainage section 1222 is connected to the water receiving section 1221A, the drainage section 1221B, and the drain outlet 1211A. By setting the drainage section 1222, a continuous and directional drainage path is formed. After water enters from the relief port 112, it is received by the water receiving section 1221A and quickly guided to the drain outlet 1211A through the bent drainage section 1222, reducing the retention time of water inside.

[0057] The bent design of the drain section 1222 increases the path length and direction of water flow, reduces the possibility of backflow, and ensures that water can be discharged smoothly. The bent drain section 1222 can be adjusted according to the specific internal structure to ensure that the drain outlet 1211A can cover all possible water inlets and adapt to the complex layout of the interlock drive assembly 122, thereby further improving the waterproof performance of the door interlock mechanism 12 and enhancing the waterproof performance and reliability of the microwave cooking equipment.

[0058] In an embodiment of this utility model, the interlocking drive assembly 122 is provided with a water-blocking part 1223, which is located between the flow channel 1221 and the micro switch assembly 13.

[0059] In detail, by setting up the water-blocking part 1223, multiple protections are provided. The water-blocking part 1223 is located between the drainage channel 1221 and the micro switch assembly 13. It can prevent water from flowing directly to the micro switch assembly 13. Even if a small amount of water enters through the relief port 112, it will be intercepted by the water-blocking part 1223 and then discharged through the drainage channel 1221, instead of directly contacting the micro switch assembly 13. This effectively prevents water from leaking out of the drainage channel 1221, further improving the waterproof effect and enhancing the user experience.

[0060] The water-blocking part 1223 can be disposed in different positions according to specific needs. The shape of the water-blocking part 1223 can be a protrusion or an extended water-blocking block. In one embodiment, as shown... Figure 7 The water-blocking part 1223 is located at the relief opening 112. When water enters through the relief opening 112, it can block the water, intercepting it as soon as it enters, reducing the possibility of water entering the groove structure 1211. In another embodiment, as... Figure 11 The water-blocking part 1223 is located in the middle of the interlock drive assembly 122. When water flows to the drain outlet 1211A, it can better prevent water from leaking out of the diversion channel 1221. It also intercepts water as it flows along the diversion channel 1221 to ensure that water does not leak out of the diversion channel 1221.

[0061] In an embodiment of this utility model, the groove structure 1211 includes a first groove 1211B and a second groove 1211C; the interlocking drive assembly 122 includes a first drive member (not shown) and a second drive member (not shown); the first drive member is movably connected in the first groove 1211B, and the second drive member is movably connected in the second groove 1211C; the first drive member and the second drive member respectively trigger the micro switch assembly 13; the clearance port 112 includes a first opening 1121 and a second opening 1122; the first drive member is at least partially located in the first opening 1121, and the second drive member is at least partially located in the second opening 1122; the drain port 1211A extends along the arrangement direction of the first drive member and the second drive member, and passes through the first groove 1211B and the second groove 1211C; the drain port 1211A communicates with the first opening 1121 and the second opening 1122.

[0062] Specifically, the interlocking drive assembly 122 is designed as a first drive element and a second drive element. The first and second drive elements respectively trigger the microswitch assembly 13, providing a double safety mechanism. Even if one drive element fails, the other drive element can still ensure that the microwave cooking appliance 100 will not start if the lid 20 is not fully closed, thus avoiding potential safety risks and ensuring greater user safety. The groove structure 1211 is also configured as a first groove 1211B and a second groove 1211C, separately installing the first and second drive elements in the two grooves, which can better distribute the load and improve the overall structural stability.

[0063] The first groove 1211B and the second groove 1211C are respectively set to correspond to the first opening 1121 and the second opening 1122. No matter which opening the water enters from, it will flow along the first driving member or the second driving member to the first groove 1211B and the second groove 1211C. The micro switch assembly 13 is still located outside the first groove 1211B and the second groove 1211C. The water that enters can flow out from the drain 1211A without interfering with the micro switch assembly 13, thus reducing the risk of water ingress.

[0064] The drain outlet 1211A extends along the arrangement direction, covering the entire length of the first groove 1211B and the second groove 1211C, and penetrating both grooves. This ensures that water entering from the first opening 1121 and the second opening 1122 can be quickly guided to the drain outlet 1211A, allowing water to drain rapidly along this path and preventing water accumulation in any specific area, thus ensuring comprehensive drainage. The extension of the drain outlet 1211A can be adjusted according to the specific form of the first groove 1211B and the second groove 1211C to ensure that the drain outlet 1211A can cover all possible water inlet points.

[0065] In addition, the interlocking drive assembly 122 also includes a first return spring 1228 and a second return spring 1229; one end of the first return spring 1228 is connected to the wall of the first groove 1211B, and the other end is connected to the first drive member; one end of the second return spring 1229 is connected to the wall of the second groove 1211C, and the other end is connected to the first drive member. By setting the first return spring 1228 and the second return spring 1229, the return springs provide a continuous return force and can provide a rapid return force, ensuring that the drive member quickly returns to its initial position after the cover 20 is closed, improving the system's response speed and enhancing the user experience.

[0066] In an embodiment of this utility model, the micro switch assembly 13 includes a first micro switch 131, a second micro switch 132, and a third micro switch 133. The first micro switch 131, the second micro switch 132, and the third micro switch 133 are all connected to the interlocking bracket 121 and located outside the groove structure 1211. The first micro switch 131 and the third micro switch 133 are respectively corresponding to the first driving member, and the second micro switch 132 is corresponding to the second driving member. The first driving member and the second driving member are used to sequentially trigger the first micro switch 131, the second micro switch 132, and the third micro switch 133.

[0067] In detail, three independent microswitches provide multiple safety mechanisms to ensure that the microwave cooking appliance 100 will not be activated if the lid 20 is not fully closed, thus avoiding potential safety risks.

[0068] The first microswitch 131 and the third microswitch 133 are respectively configured to correspond to the first driving member, ensuring that the first driving member can trigger the corresponding microswitch when in different positions. The second microswitch 132 is configured to correspond to the second driving member, ensuring that the second driving member can trigger the corresponding microswitch when in different positions. The first driving member and the second driving member sequentially trigger the first microswitch 131, the second microswitch 132, and the third microswitch 133, ensuring that the door interlocking mechanism 12 responds correctly at each stage.

[0069] The micro switch assembly 13 is located outside the groove structure 1211, away from areas where water may enter. The first and second drive members move inside the groove, while the micro switch assembly 13 is outside the groove. This physical isolation ensures that water will not directly contact the micro switch assembly 13. The design of the drain port 1211A further ensures that water entering the groove structure 1211 can be quickly discharged, reducing the retention time of water inside.

[0070] In an embodiment of this utility model, the first driving member includes a first interlocking lever 1224, which is rotatably connected to the first groove 1211B. The second driving member includes a second interlocking lever 1225, which is rotatably connected to the first groove 1211B. The first interlocking lever 1224 is used to trigger the first micro switch 131 and the third micro switch 133, and the second interlocking lever 1225 is used to trigger the second micro switch 132.

[0071] Specifically, in one embodiment, such as Figure 1-3 and Figure 7-10The first interlocking lever 1224 and the second interlocking lever 1225 are rotatably connected to the first groove 1211B and the second groove 1211C, respectively. A first micro switch 131, a second micro switch 132, and a third micro switch 133 are provided. The first micro switch 131 is normally closed, while the second micro switch 132 and the third micro switch 133 are normally open. The cover 20 is provided with two pins 21. When the cover is closed, the first interlocking lever 1224 and the second interlocking lever 1225 rotate in sequence under the action of the pins 21, and the three micro switches are activated in the order of first micro switch 131-second micro switch 132-third micro switch 133, with an action interval of more than 10ms. That is, when the cover 20 is closed, the first pin 21 first contacts the first interlocking lever 1224, causing the first interlocking lever 1224 to rotate, triggering the first micro switch 131 to change from the normally closed state to the open state; then, the second pin 21 contacts the second interlocking lever 1225, causing the second interlocking lever 1225 to rotate, triggering the second micro switch 132 to change from the normally open state to the closed state; finally, as the cover 20 continues to close, the first interlocking lever 1224 rotates further, triggering the third micro switch 133 to change from the normally open state to the closed state. Throughout the process, the action interval of the three micro switches is greater than 10ms, which can ensure the action sequence and reliability of each micro switch.

[0072] like Figure 7-10 Both the first interlocking lever 1224 and the second interlocking lever 1225 are provided with a flow channel 1221 and a water-blocking part 1223, and the first interlocking lever 1224 is provided with a flow channel 1222, to ensure that each micro switch is not affected by moisture and to reduce the risk of water ingress.

[0073] In an embodiment of this utility model, the first driving member includes a third interlocking lever 1226, which is rotatably connected to the first groove 1211B. The second driving member includes an interlocking slider 1227, which is movably disposed in the second groove 1211C. The third interlocking lever 1226 is used to trigger the first micro switch 131 and the third micro switch 133, and the interlocking slider 1227 is used to trigger the second micro switch 132.

[0074] Specifically, in another embodiment, such as Figure 4-6 and Figure 11-13The third interlocking lever 1226 is rotatably connected to the first groove 1211B, and the interlocking slider 1227 is slidably disposed in the second groove 1211C. A first micro switch 131, a second micro switch 132, and a third micro switch 133 are provided, wherein the first micro switch 131 is normally closed, and the second micro switch 132 and the third micro switch 133 are normally open. The cover 20 is provided with a pin 21 and a contact point 22. When the cover is closed, under the action of the pin 21 and the contact point 22, the third interlocking lever 1226 rotates and the interlocking slider 1227 slides, and the three micro switches are activated in the following order: first micro switch 131 - second micro switch 132 - third micro switch 133, with an action interval greater than 10ms. In other words, when the cover 20 is closed, the latch 21 first contacts the third interlocking lever 1226, causing the third interlocking lever 1226 to rotate and triggering the first micro switch 131 to change from the normally closed state to the open state; subsequently, the contact point 22 contacts the interlocking slider 1227, causing the interlocking slider 1227 to slide and triggering the second micro switch 132 to change from the normally open state to the closed state; finally, as the cover 20 continues to close, the third interlocking lever 1226 rotates further, triggering the third micro switch 133 to change from the normally open state to the closed state; throughout the process, the action interval of the three micro switches is greater than 10ms, which can ensure the action sequence and reliability of each micro switch.

[0075] like Figure 6 and Figure 11 Both the third interlocking lever 1226 and the interlocking slider 1227 are equipped with a drainage groove 1221 and a water-blocking part 1223 to ensure that each micro switch is not affected by water and to reduce the risk of water ingress.

[0076] In addition, such as Figure 8 , Figure 10 , Figure 11 and Figure 13 As shown in the figure, the dashed arrows indicate the flow direction of water after it enters from the first opening 1121 and the second opening 1122. The water flows through the diversion channel 1221 and is finally discharged from the drain outlet 1211A.

[0077] This utility model also provides a microwave cooking appliance 100, including a cover 20 and a cooking body 10 as described above. The cover 20 is provided with a pin 21, which is provided corresponding to the clearance opening 112. The cover 20 covers the cooking body 10, and the pin 21 extends into the clearance opening 112 to drive the interlocking drive assembly 122 to move, thereby triggering the micro switch assembly 13.

[0078] Specifically, a pin 21 is provided on the wall surface of the cover 20 facing the cooking body 10. When the cover 20 is closed on the cooking body 10, the pin 21 also extends into the clearance opening 112 and drives the interlock drive assembly 122 to move, thereby triggering the micro switch assembly 13 and starting the microwave cooking appliance 100.

[0079] In one embodiment, such as Figure 6 and Figure 13 As shown, the door interlock mechanism 12 is installed at the front end of the housing 11, near the button opening position. The first micro switch 131 is normally closed, and the second micro switch 132 and the third micro switch 133 are normally closed. Figure 2 The cover 20 has two pins 21. When the cover is closed, the pins 21 cause the first driving member and the second driving member (the first interlocking lever 1224 and the second interlocking lever 1225) to rotate and cause the three micro switches to start in the order of the first micro switch 131-the second micro switch 132-the third micro switch 133, with an action interval of more than 10ms.
