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.

The water droplets will flow away along the walls of the groove structure and the interlocking drive assembly, draining naturally and preventing accumulation near the micro switch assembly. This reduces the risk of water ingress, protects sensitive electronic components, improves the waterproof performance of the equipment, and makes the equipment safer and more reliable during use.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0035] 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.

[0036] In view of this, for the microwave cooking appliances with top-opening lids mentioned above, the opening corresponding to the door interlock mechanism faces the top surface, 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, aiming to improve the problem of high risk of water ingress in the door interlock mechanism.

[0037] The specific structures of the cooking body 10 and the microwave cooking appliance 100 of this utility model will be described below:

[0038] Please refer to Figures 1 to 12This 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 on the cooking body 10. Within the mounting cavity 111, the interlocking bracket 121 includes a groove structure 1211 and a mounting plate structure 1212. The groove structure 1211 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. The mounting plate structure 1212 is connected to the groove sidewall of the groove structure 1211 and is located outside the groove structure 1211. A micro switch assembly 13 is also provided within the mounting plate structure 1212.

[0039] 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.

[0040] The door interlocking mechanism 12 is provided with an interlocking bracket 121 and an interlocking drive assembly 122. The interlocking bracket 121 is used to support and install the interlocking drive assembly 122 and the micro switch assembly 13. The interlocking drive assembly 122 is correspondingly arranged with the micro switch assembly 13. The interlocking drive assembly 122 is used to trigger the micro switch assembly 13. A groove structure 1211 is recessed on one side of the interlocking bracket 121, and a protruding mounting plate structure 1212 is provided on this side. The interlocking drive assembly 122 is installed in the groove structure 1211, and the micro switch assembly 13 is installed on the mounting plate structure 1212. A clearance opening 112 is provided on the outer shell 11. When the cover 20 is closed, the drive part on the cover 20 can drive the interlocking drive assembly 122 to move through the clearance opening 112 to trigger the micro switch assembly 13.

[0041] The groove structure 1211 and the mounting plate structure 1212 have a thickness difference relative to the interlock bracket 121, which makes the clearance port 112 and the interlock drive assembly 122 and the micro switch assembly 13 misaligned along the thickness direction of the interlock bracket 121. The misalignment design can reduce the risk of water ingress of the micro switch assembly 13 to a certain extent.

[0042] 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 is connected to the relief port 112, and water droplets enter from the relief port 112 and can directly leak along the groove structure 1211 into the bottom of the housing 11 without interfering with the micro switch assembly 13.

[0043] The groove structure 1211 can be an open groove with a bottom surface and two or more sides; it can also be a guide groove with a water guide channel or water guide path inside to guide the incoming water droplets to a specific drainage area; or it can be an inclined groove with the bottom or sides of the groove designed at an inclined angle so that the water droplets can slide down naturally.

[0044] The groove structure 1211 is connected to the relief port 112. The relief port 112 is offset from the micro switch assembly 13. Even if a small amount of water droplets enter the groove structure 1211 from the relief port 112, they will not directly contact the mounting plate structure 1212 and the micro switch assembly 13. The water can also be drained to the bottom of the housing 11 by natural drainage and discharged from the heat dissipation holes at the bottom of the housing 11, preventing it from accumulating near the micro switch assembly 13.

[0045] The mounting plate structure 1212 can be a flat mounting plate with holes or slots for fixing the micro switch assembly 13; it can also be a mounting bracket for mounting and fixing the micro switch assembly 13; or it can be a mounting plate with clips or positioning pins to ensure the precise installation position of the micro switch. By providing additional support through the mounting plate structure 1212, the micro switch assembly 13 is fixed.

[0046] By setting the groove structure 1211 to cooperate with the mounting plate structure 1212, the protrusion of the mounting plate structure 1212 causes the micro switch assembly 13 and the clearance port 112 to be misaligned in the thickness direction of the interlocking bracket 121, forming a thickness difference. This thickness difference forms a waterproof barrier. Even if water droplets enter from the clearance port 112, they will first fall on the groove structure 1211 or the interlocking drive assembly 122, and will not drip directly onto the micro switch assembly 13, thereby reducing the risk of water ingress.

[0047] Since water flow typically follows the surface of the first part that comes into contact with it, water droplets will flow along the groove structure 1211 or the interlocking drive assembly 122 towards the bottom of the housing 11, without affecting the micro switch assembly 13, thus effectively protecting the micro switch assembly 13 from damage by water droplets. Furthermore, the combination of the groove structure 1211 and the mounting plate structure 1212 allows the interlocking drive assembly 122 and the micro switch assembly 13 to be compactly installed inside the housing 11, making full use of the limited space.

[0048] This utility model's technical solution involves designing a groove structure 1211 on the interlocking bracket 121 that cooperates with the mounting plate structure 1212. This causes the micro switch assembly 13 and the clearance port 112 to be misaligned in the thickness direction of the interlocking bracket 121. Even if water droplets enter from the clearance port 112, they will first fall onto the groove structure 1211 and the interlocking drive assembly 122, effectively preventing water droplets from directly contacting the micro switch assembly 13. The water droplets will flow away along the walls of the groove structure 1211 and the interlocking drive assembly 122 and be discharged naturally, preventing accumulation near the micro switch assembly 13. This reduces the risk of water ingress, protects sensitive electronic components, improves the waterproof performance of the equipment, and makes the equipment safer and more reliable during use.

[0049] In an embodiment of this utility model, the micro switch assembly 13 and the clearance port 112 are misaligned in projection on the horizontal plane.

[0050] In detail, such as Figure 3 and Figure 8 The micro switch assembly 13 and the relief port 112 are offset in projection on the horizontal plane, that is, the micro switch assembly 13 is not directly below the relief port 112, so even if water droplets enter from the relief port 112, they will not drip directly onto the micro switch assembly 13.

[0051] By using a horizontally offset design, the natural flow path of water droplets is guided to a location away from the microswitch assembly 13, thus avoiding direct contact. Even if a small amount of water droplets enters, they will be discharged naturally, preventing them from accumulating near the microswitch assembly 13. The water droplets will flow away along other paths and eventually be discharged or remain in a position that will not affect the microswitch assembly 13. This can significantly improve the waterproof performance of the device and reduce the damage of water droplets to internal electronic components.

[0052] In an embodiment of this utility model, the distance between the projections of the micro switch assembly 13 and the clearance port 112 on the horizontal plane is 1mm-4mm. Here, the distance refers to the minimum distance between the two features, that is, the distance between the two points on the two features that are closest to each other.

[0053] By setting the spacing between 1mm and 4mm, sufficient distance is ensured so that water droplets do not drip directly from the relief opening 112 onto the microswitch assembly 13, effectively improving waterproof performance. Simultaneously, within this range, internal space is maximized, keeping the device structure compact. This helps reduce the overall size and improves the portability and aesthetics of the microwave cooking appliance 100.

[0054] In an embodiment of this utility model, the micro switch assembly 13 and the interlocking drive assembly 122 are both installed on the same side of the mounting plate structure 1212.

[0055] In detail, such as Figure 3 The micro switch assembly 13 and the interlocking drive assembly 122 are both mounted on the same side of the mounting plate structure 1212, forming a unified waterproof barrier. The groove structure 1211 effectively blocks water droplets entering from the relief opening 112, preventing them from directly contacting the micro switch assembly 13 and significantly improving waterproof performance. Simultaneously, mounting the micro switch assembly 13 and the interlocking drive assembly 122 on the same side fully utilizes internal space, making the entire door interlocking mechanism 12 more compact and reducing its overall size. Furthermore, centralized mounting on the same side simplifies the design, reduces unnecessary structural complexity, and lowers manufacturing and assembly difficulties.

[0056] In an embodiment of this utility model, the groove structure 1211 includes a first groove 1211A and a second groove 1211B; 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 1211A, and the second drive member is movably connected in the second groove 1211B; the clearance port 112 includes a first opening 1121 and a second opening 1122; the first groove 1211A communicates with the first opening 1121, and the second groove 1211B communicates with the 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.

[0057] Specifically, the interlocking drive assembly 122 is designed as a first drive and a second drive. The micro switch assembly 13 is triggered by the first drive and the second drive respectively, which provides a double insurance mechanism. Even if one drive fails, the other drive can still ensure that the microwave cooking appliance 100 will not be started if the cover 20 is not completely closed, thereby avoiding potential safety risks and ensuring greater safety for the user during use.

[0058] The groove structure 1211 is also configured with a first groove 1211A and a second groove 1211B. By separately installing the first driving component and the second driving component in the two grooves, the load can be better distributed, improving the stability of the overall structure. At the same time, the first groove 1211A and the second groove 1211B are respectively set to correspond to the first opening 1121 and the second opening 1122. Each driving component has an independent groove and opening, which can form multiple waterproof barriers. Even if water droplets enter from a certain opening, they will only be confined to the corresponding first groove 1211A or second groove 1211B and will not spread to other parts, reducing the risk of water droplets entering the internal components.

[0059] In another embodiment, such as Figure 3 and Figure 6The first groove 1211A and the second groove 1211B are connected to form a continuous groove structure 1211. The mounting plate structure 1212 is located outside the first groove 1211A and the second groove 1211B, which can provide a more effective waterproof barrier. After water droplets enter any opening, they will be confined within the connected grooves, making it difficult for them to further penetrate into the micro-switch assembly 13 or other sensitive components. The connected grooves can also evenly distribute the load and make the door interlocking mechanism 12 more integrated, reducing the burden on individual grooves or drive components and improving the stability of the overall structure.

[0060] In an embodiment of this utility model, the interlocking drive assembly 122 further includes a first reset spring 1225 and a second reset spring 1226; one end of the first reset spring 1225 is connected to the wall of the first groove 1211A, and the other end of the first reset spring 1225 is connected to the first drive member; one end of the second reset spring 1226 is connected to the wall of the second groove 1211B, and the other end of the second reset spring 1226 is connected to the first drive member.

[0061] In detail, by setting the first reset spring 1225 and the second reset spring 1226, the reset spring provides a continuous reset force and can provide a rapid reset force, ensuring that the drive component quickly returns to the initial position after the cover 20 is closed, thereby improving the system's response speed and enhancing the user experience.

[0062] like Figure 7 and Figure 10 A connecting arm protrudes from the wall of the first groove 1211A, and a connecting arm is also provided on the first driving member. The two ends of the first return spring 1225 are sleeved on the two connecting arms for connection, making the connection more stable. Similarly, the two ends of the second return spring 1226 are also connected to the connecting arms on the second groove 1211B and the first driving member, respectively.

[0063] In an embodiment of this utility model, the first driving member includes a first interlocking lever 1221, which is rotatably connected to the first groove 1211A; the second driving member includes a second interlocking lever 1222, which is rotatably connected to the second groove 1211B; or, the first driving member includes a third interlocking lever 1223, which is rotatably connected to the first groove 1211A; and the second driving member includes an interlocking slider 1224, which is slidably disposed in the second groove 1211B.

[0064] Specifically, in one embodiment, such as Figure 7 and Figure 9The first driving component and the second driving component are respectively configured as the first interlocking lever 1221 and the second interlocking lever 1222. The first interlocking lever 1221 and the second interlocking lever 1222 are rotatably connected in the first groove 1211A and the second groove 1211B respectively. Both interlocking levers realize the interlocking function by rotating. The structure is relatively simple, easy to design and manufacture, and can quickly respond to the opening and closing of the door, improve the response speed of the system, and is suitable for application scenarios that require frequent opening and closing of doors.

[0065] In another embodiment, the first driving member and the second driving member are respectively configured as a third interlocking lever 1223 and an interlocking slider 1224. The third interlocking lever 1223 is rotatably connected in the first groove 1211A, and the interlocking slider 1224 is slidably disposed in the second groove 1211B. Combining two different motion modes, rotation and sliding, provides more design flexibility. The sliding motion of the interlocking slider 1224 can be applied to scenarios with high precision requirements for the interlocking mechanism, and the interlocking slider 1224 can provide more accurate positioning.

[0066] By setting two different implementations, different application scenarios and needs can be adapted, providing more design options. The most suitable interlocking mechanism can be selected according to specific application requirements. For example, setting the first interlocking lever 1221 and the second interlocking lever 1222 is suitable for scenarios that require frequent door opening and closing, limited internal space, and simple maintenance; setting the third interlocking lever 1223 and the interlocking slider 1224 is suitable for scenarios that require high precision and multi-functionality.

[0067] In an embodiment of this utility model, the mounting plate structure 1212 includes a first mounting plate 1212A, a second mounting plate 1212B, and a third mounting plate 1212C; the micro switch assembly 13 includes a first micro switch 131, a second micro switch 132, and a third micro switch 133, wherein the first micro switch 131 is mounted on the first mounting plate 1212A, the second micro switch 132 is mounted on the second mounting plate 1212B, and the third micro switch 133 is mounted on the third mounting plate 1212C; the interlocking drive assembly 122 is used to sequentially drive the first micro switch 131, the second micro switch 132, and the third micro switch 133.

[0068] In detail, the three independent microswitches provide multiple safety mechanisms to ensure that the microwave cooking appliance 100 will not be activated if the cover 20 is not fully closed, avoiding potential safety risks; the interlock drive assembly 122 sequentially drives the first microswitch 131, the second microswitch 132 and the third microswitch 133, improving the reliability of use; the independent mounting plate and microswitches can make more rational use of the internal space, making the entire door interlock mechanism 12 more compact.

[0069] Each mounting plate is located outside the groove structure 1211. The first mounting plate 1212A, the second mounting plate 1212B and the third mounting plate 1212C are all designed to be staggered with the groove structure 1211. Each micro switch and the mounting plate form an independent waterproof unit. Even if water droplets enter from the relief port 112, it will not affect the three micro switches.

[0070] In one embodiment, such as Figure 1-3 and Figure 7-9 The first interlocking lever 1221 and the second interlocking lever 1222 are rotatably connected in the first groove 1211A and the second groove 1211B, 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, and 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 1221 and the second interlocking lever 1222 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 1221, causing the first interlocking lever 1221 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 1222, causing the second interlocking lever 1222 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 1221 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.

[0071] In another embodiment, such as Figure 4-6 and Figure 10-12The third interlocking lever 1223 is rotatably connected in the first groove 1211A, and the interlocking slider 1224 is slidably disposed in the second groove 1211B. 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 1223 rotates and the interlocking slider 1224 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 1223, causing the third interlocking lever 1223 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 1224, causing the interlocking slider 1224 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 1223 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] In an embodiment of this utility model, the first mounting plate 1212A, the second mounting plate 1212B, and the third mounting plate 1212C are all provided with connecting buckles 1212D; the first micro switch 131, the second micro switch 132, and the third micro switch 133 are respectively connected to the first mounting plate 1212A, the second mounting plate 1212B, and the third mounting plate 1212C through the connecting buckles 1212D.

[0073] It is worth noting that the design of the connecting clip 1212D provides a secure connection, ensuring that the micro switch will not loosen or fall off during use; and allows the first micro switch 131, the second micro switch 132, and the third micro switch 133 to be quickly installed onto the first mounting plate 1212A, the second mounting plate 1212B, and the third mounting plate 1212C without the need for screws or other tools, thus improving assembly efficiency; similarly, the connecting clip 1212D also allows the micro switch to be quickly disassembled, facilitating maintenance and repair, and improving assembly and maintenance efficiency.

[0074] In an embodiment of this utility model, the groove sidewall of the groove structure 1211 is provided with a drain outlet 1211C, which is connected to the clearance port 112.

[0075] In detail, by setting a drain outlet 1211C, which is connected to the relief port 112, a clear drainage path is formed. After water droplets enter the groove, they will flow along the side wall of the groove to the drain outlet 1211C and be discharged to the bottom of the housing 11 through the drain outlet 1211C, or flow directly from the relief port 112 to the drain outlet 1211C. This ensures that the water entering the groove can be discharged quickly, preventing water from accumulating in the groove, thereby protecting the micro switch assembly 13 from the influence of water.

[0076] like Figure 8 , Figure 9 , Figure 10 and Figure 12 As shown in the figure, the dashed arrows indicate the flow direction of water after it enters through the first opening 1121 and the second opening 1122, and the water is finally discharged from the drain outlet 1211C.

[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 and drives the interlocking drive assembly 122 to trigger 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 1 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 and second driving components (first interlocking lever 1221 and second interlocking lever 1222, or third interlocking lever 1223 and interlocking slider 1224) to rotate and cause the three microswitches to start in the order of first microswitch 131-second microswitch 132-third microswitch 133, with an action interval greater than 10ms.

[0080] The specific structure of the cooking body 10 is as described in the above embodiments. Since the microwave cooking appliance 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0081] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
