Description

Technical Field

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

[0002] Microwave cooking appliances consist of a metal inner pot and a grill rack inside the inner pot. In actual use, it is essential to ensure that the grill rack and the inner wall of the inner pot do not come into contact, otherwise it may cause sparking and damage.

[0003] To address these issues, existing grills have insulating structures on their sides to prevent sparking from contacting the inner liner's side walls. Furthermore, since the grill has legs, to prevent the legs from contacting the inner liner's side walls, leg covers are installed on the legs to prevent the grill from contacting the bottom wall of the inner liner.

[0004] While the above methods solve the problems to some extent, they result in a relatively complex structure, requiring insulation on both the legs and sides. Furthermore, they cannot guarantee that users will not come into contact with the inner wall of the liner when the liner is placed haphazardly, thus still posing a certain risk. Utility Model Content

[0005] Therefore, it is necessary to provide a microwave cooking appliance that has a simple structure and can prevent sparking, in order to address the above problems.

[0006] This utility model provides a microwave cooking appliance, including: an inner pot; a support plate located on the bottom wall of the inner pot; and a metal grill rack movably placed in the inner pot. The metal grill rack includes a frame and legs. One end of the legs is connected to the frame, and the other end is supported on the support plate. An insulating element protrudes from the outer edge of the frame along its circumference. When the metal grill rack is located in any position in the inner pot, a first distance L1 is between the outer edge of the frame and the inner wall of the inner pot in any direction, and a second distance L2 is between the supporting end of the legs and the outer edge of the support plate in the same direction, wherein L1 < L2.

[0007] In the aforementioned microwave cooking appliance, when the metal grill rack is placed inside the inner pot, the outer edge of the rack is provided with an insulating component, ensuring that the outer edge of the rack will not contact the inner wall of the inner pot. Simultaneously, when any position of the insulating component contacts the inner wall of the inner pot, the first distance L1 between the outer edge of the rack at that position and the inner wall of the inner pot is minimized, satisfying L1 > 0. The second distance in this direction between the supporting end of the leg and the outer edge of the support plate satisfies L2 > L1 > 0. When the insulating component does not contact the inner wall of the inner pot, the first distance L1 and the second distance L2 are larger. This ensures that regardless of how the metal grill rack is placed, the supporting end of the leg remains within the support plate and does not contact the bottom wall of the inner pot, thus preventing arcing during microwave cooking. Furthermore, precise control of the metal grill rack's placement is unnecessary, improving the product's safety and convenience. Additionally, no additional insulating components are needed on the supporting end of the leg, simplifying the overall structure of the metal grill rack and microwave cooking appliance, thereby reducing costs and assembly complexity.

[0008] In one embodiment, the third distance between the outer edge of the support plate and the inner wall of the inner liner in any direction is L3, and the fourth distance between the supporting end of the leg and the outer edge of the frame in that direction is L4, and L3 < L4, wherein the fourth distance is the distance between the supporting end of the leg and the projection of the outer edge of the frame onto the support plate.

[0009] This design further ensures that the support end of the legs is always located within the support plate, avoiding arcing during microwave cooking and providing double protection for the microwave cooker; by defining the relationship between the two fixed dimensions, the third distance L3 and the fourth distance L4, it also facilitates production and processing.

[0010] In one embodiment, the metal grill is square or round.

[0011] This design allows the square metal grill rack to effectively utilize the space inside the square grill liner; furthermore, both square and round metal grill racks have simple structures, making them easy to manufacture and process.

[0012] In one embodiment, the metal grill is square, and insulating elements are provided at all four corners of the metal grill.

[0013] This design ensures that the metal grill will not come into contact with the inner wall of the liner, regardless of the angle at which it is placed, providing precise protection. It also saves on insulation materials, reducing costs and the weight of the metal grill.

[0014] In one embodiment, the insulating element is a silicone element.

[0015] This design gives the silicone parts good insulation and high-temperature resistance, meeting the requirements of microwave cooking equipment to prevent microwave arcing and ensuring safety. The silicone parts are also elastic, providing cushioning and protection, and are not easily damaged, extending their service life. The silicone parts are also low in cost and easy to manufacture.

[0016] In one embodiment, the insulating element is fixed to the frame.

[0017] This design ensures the stability and reliability of the connection between the insulation components and the frame, and the integrated frame and insulation components do not require alignment during installation, making it convenient for users.

[0018] In one embodiment, the insulating component and the frame are integrally molded using an injection molding process.

[0019] This configuration simplifies the injection molding process, reduces costs, and ensures high dimensional accuracy. It also improves the reliability of the connection between the insulation components and the frame, ensuring a seamless connection between them.

[0020] In one embodiment, the frame and the support legs are integrally formed.

[0021] This design improves the overall integrity and consistency of the frame and legs, ensuring the structural strength and stability of the metal grill, while also ensuring a seamless connection between the frame and legs. The one-piece frame and legs also simplify the production process and assembly steps of the metal grill, reducing costs.

[0022] In one embodiment, the frame includes a support rod located on the outer ring and a plurality of connecting rods, both ends of the plurality of connecting rods being connected to the support rod, and adjacent connecting rods being spaced apart, some of the connecting rods being bent downward to form the support legs, and the insulating element being disposed on the support rod.

[0023] With this configuration, the support rods are used to connect and support the connecting rods. The support rods are located on the periphery of the metal grill and the insulating parts are placed on the support rods to ensure that the grill body does not come into contact with the inner wall of the inner liner. The legs are formed by bending some of the connecting rods downwards, which can ensure the strength and stability of the metal grill, facilitate processing, and also reduce the number of parts and reduce the overall weight of the metal grill.

[0024] In one embodiment, the support plate is made of microcrystalline glass.

[0025] This design ensures the proper functioning of the microwave system, and the high temperature resistance, high strength, and easy cleaning of the microcrystalline glass ensure the safety of the support plate and extend its service life. Attached Figure Description

[0038] Microwave cooking appliances consist of a metal inner pot and a grill rack located within it. During actual use, it is crucial to ensure that the grill rack does not come into contact with the inner wall of the pot; otherwise, sparking and damage may occur. To address this issue, existing grill racks have insulating structures on their sides to prevent contact with the inner pot's side walls and subsequent sparking. Furthermore, since the grill rack has legs, foot covers are provided on the legs to prevent contact with the inner pot's side walls and thus avoid contact with the bottom wall of the inner pot. While these methods solve the problem to some extent, they result in a relatively complex structure, requiring insulating structures on both the legs and sides. Moreover, they do not guarantee that users will not come into contact with the inner pot's inner wall when placing the appliance haphazardly, thus still posing a certain risk.

[0039] To solve the above problems, such as Figures 1 to 5 As shown, this utility model provides a microwave cooking appliance with a simple structure that avoids sparking. This microwave cooking appliance can be a microwave oven, a steam oven / microwave combo, or other cooking equipment with microwave functionality.

[0040] like Figures 1 to 3As shown, specifically, the microwave cooking appliance includes an inner pot 10, a support plate 20, and a metal grill rack 30. The support plate 20 is located on the bottom wall of the inner pot 10. The metal grill rack 30 is movably placed in the inner pot 10. The metal grill rack 30 includes a frame 31 and legs 32. One end of the legs 32 is connected to the frame 31, and the other end can be supported on the support plate 20. The other end is connected to the frame 31. Along the circumference of the frame 31, an insulating element 33 protrudes from the outer edge of the frame 31. When the metal grill rack 30 is located in any position in the inner pot 10, the first distance between the outer edge of the frame 31 and the inner wall of the inner pot 10 in any direction is L1, and the second distance between the supporting end of the legs 32 and the outer edge of the support plate 20 in the same direction is L2, where L1 < L2. The support plate 20 is made of insulating material to ensure that contact between the supporting end of the legs 32 and the support plate 20 will not cause sparking.

[0041] It should be noted that "any direction" refers to the direction along the circumference of the rack 31, that is, the horizontal direction when the microwave cooking appliance is placed horizontally. Furthermore, the first distance refers to the minimum distance between the outer edge of the rack 31 and the inner wall of the inner pot 10 in this direction. Since the relative positions of the inner pot 10 and the support plate 20 are fixed, and the relative positions of the rack 31 and the legs 32 are also fixed, the first distance L1 and the second distance L2 will change when the user places the metal grill 30 in different positions within the inner pot 10; that is, the first distance L1 and the second distance L2 are dynamic dimensions. For example, when the metal grill 30 is placed in the center, the first distance L1 between the outer edge of the rack 31 and the two opposite inner walls of the inner pot 10 is equal; when the metal grill 30 is placed closer to one of the inner walls, the first distance L1 between the outer edge of the rack 31 and that side of the inner pot 10 is smaller, and the first distance L1 between the outer edge of the rack 31 and the opposite side of the inner pot 10 is larger, and the second distance L2 will also change accordingly.

[0042] In the microwave cooker provided in this embodiment of the present invention, when the metal grill rack 30 is placed inside the inner pot 10, the outer edge of the rack 31 is provided with an insulating member 33, which ensures that the outer edge of the rack 31 will not contact the inner wall of the inner pot 10. At the same time, when any position of the insulating member 33 contacts the inner wall of the inner pot 10, the first distance L1 between the outer edge of the rack 31 corresponding to that position and the inner wall of the inner pot 10 is the smallest and satisfies L1 > 0. The second distance in this direction between the supporting end of the leg 32 and the outer edge of the support plate 20 satisfies L2 > L1 > 0. When the insulating member 33 does not contact the inner wall of the inner pot 10, the first distance L1 and the second distance L2 are larger. In this way, it is ensured that no matter how the metal grill 30 is placed, the supporting end of the leg 32 is always located inside the support plate 20 and will not contact the bottom wall of the inner pot 10, thereby avoiding arcing under microwave function. It also eliminates the need for precise control of the placement of the metal grill 30, improving the safety and convenience of the product. Furthermore, no additional insulating components are required on the supporting end of the leg 32, making the overall structure of the metal grill 30 and microwave cooker simple, thereby reducing costs and assembly complexity.

[0043] like Figures 2 to 3 As shown, the third distance between the outer edge of the support plate 20 and the inner wall of the inner pot 10 in any direction is L3, and the fourth distance between the supporting end of the leg 32 and the outer edge of the frame 31 in that direction is L4, satisfying L3 < L4. The fourth distance is the distance between the projections of the supporting end of the leg 32 and the outer edge of the frame 31 onto the support plate 20. It should be noted that the third distance L3 and the fourth distance L4 are determined by the processing dimensions of the inner pot 10, the support plate 20, and the metal grill 30; that is, the third distance L3 and the fourth distance L4 are fixed dimensions. Thus, regardless of how the metal grill 30 is placed, the supporting end of the leg 32 cannot contact the bottom wall of the inner pot 10, further ensuring that the supporting end of the leg 32 is always within the support plate 20, avoiding arcing under microwave function, and providing double protection for the microwave cooker. Furthermore, by defining the relationship between the two fixed dimensions, the third distance L3 and the fourth distance L4, manufacturing processes can be facilitated.

[0044] like Figures 2 to 4As shown, in one embodiment, the metal grill rack 30 is square. The square shape includes both squares and rectangles, and the four corners of the square can be right angles or rounded corners. Since the inner pot 10 and support plate 20 of most microwave cooking equipment are square, setting the metal grill rack 30 to match the inner pot 10 and support plate 20 as a square effectively utilizes the space of the inner pot 10. Furthermore, the square metal grill rack 30 has a simple structure and is easy to manufacture. Specifically, when the square metal grill rack 30 is placed parallel to the four inner sidewalls of the square inner pot 10 with its four sides parallel to them, the first distance L1 is the distance between any side of the metal grill rack 30 and the corresponding inner sidewall of the inner pot 10, and the second distance L2 is the distance between the supporting end of the leg 32 and the corresponding side of the support plate 20. Of course, the square metal grill rack 30 can also be used for other regular or irregularly shaped inner pots 10 and support plates 20, such as round or elliptical ones.

[0045] like Figure 2 and Figure 4 As shown, for a square metal grill 30, the four corners are the positions where the metal grill 30 is most likely to contact the inner wall of the inner pot 10 when it is rotated. Therefore, insulating elements 33 are provided at each of the four corners of the metal grill 30. Specifically, for each corner insulating element 33, part of the insulating element 33 is located on one side of the metal grill 30, and the remaining part is located on the other side of the metal grill 30. In this way, it is ensured that the frame 31 will not contact the inner wall of the inner pot 10 no matter what angle the metal grill 30 is placed at, achieving precise protection, while also saving the material of the insulating elements 33, reducing costs and the weight of the metal grill 30. Of course, insulating elements 33 can also be provided on the four sides of the square metal grill 30, or on the entire outer edge of the frame 31, as needed. The size and number of insulating elements 33 are not specifically limited here, as long as it is ensured that the outer edge of the frame 31 will not contact the inner wall of the inner pot 10 when the metal grill 30 is placed inside the inner pot 10.

[0046] In another embodiment, the metal grill 30 is circular. A circular metal grill 30 has a simple structure and is easy to manufacture. When the metal grill 30 is circular, multiple insulating members 33 can be provided, with each insulating member 33 spaced apart circumferentially along the metal grill 30. This ensures that, regardless of the placement of the metal grill 30, the frame 31 between any two insulating members 33 cannot contact the inner wall of the inner liner 10. Of course, in other embodiments, the metal grill 30 can also be elliptical, triangular, or other regular or irregular shapes.

[0047] like Figure 4As shown in the illustrated embodiment, there are four support legs 32, which correspond one-to-one with the four corners of the metal grill 30 to ensure the stability and reliability of the metal grill 30. Of course, the number of support legs 32 can also be one, two, three, five or more, with multiple support legs 32 arranged at intervals at the bottom of the frame 31, as long as the stability and reliability of the metal grill 30 can be ensured, and the supporting ends of the support legs 32 are always located within the support plate 20 and do not contact the bottom wall of the inner liner 10, regardless of how the metal grill 30 is placed. This embodiment of the present invention does not impose specific limitations here.

[0048] In one embodiment, the insulating component 33 is a silicone component. Silicone components possess good insulation and high-temperature resistance, effectively preventing electrical flow between the metal grill 30 and the inner pot 10. They are not easily aged or damaged even under prolonged exposure to high temperatures, meeting the requirements of microwave cooking equipment to prevent microwave arcing and ensuring safety. Silicone components are also elastic; when the metal grill 30 collides with the inner wall of the inner pot 10, the silicone component acts as a buffer and protector, preventing scratches or deformation of both. Furthermore, the silicone component itself is not easily broken, thus extending its service life. Additionally, silicone components are low in cost and easy to manufacture. Of course, in other embodiments, the insulating component 33 can also be made of rubber, high-temperature resistant plastics, or other high-temperature insulating materials, as long as they meet the requirements of microwave cooking equipment to prevent microwave arcing. This embodiment of the invention does not impose specific limitations here.

[0049] like Figure 5 As shown, in one embodiment, the insulating component 33 is fixed to the frame 31. This ensures the stability and reliability of the connection between the insulating component 33 and the frame 31, preventing the insulating component 33 from detaching during cleaning or use and thus avoiding the risk of sparking. This improves the safety of the microwave cooking equipment and extends its service life. Furthermore, the integrated frame 31 and insulating component 33 do not require alignment during installation, making it convenient for users.

[0050] In the illustrated embodiment, the insulating component 33 and the frame 31 are integrally molded using injection molding. Injection molding is a simple, low-cost process with high dimensional accuracy. Furthermore, it improves the connection reliability between the insulating component 33 and the frame 31, reduces the possibility of the insulating component 33 detaching, and ensures a seamless connection, facilitating cleaning. Of course, the insulating component 33 and the frame 31 can also be manufactured separately and fixed using adhesive bonding, pressing, or other methods, as long as the stability and reliability of the connection are ensured. This embodiment does not impose specific limitations on these methods.

[0051] In other embodiments, the insulating component 33 can also be detachably mounted on the frame 31 and connected by means of interference fit, snap-fit, threaded connection, etc., as long as the stability and reliability of the connection between the two are ensured. In this case, the user can disassemble and clean or replace the insulating component 33 and the frame 31 separately.

[0052] like Figure 4 As shown, in one embodiment, the frame 31 and the support legs 32 are integrally formed. This improves the overall integrity and consistency of the frame 31 and the support legs 32, ensuring the structural strength and stability of the metal grill 30, reducing the possibility of deformation or damage due to food loading or impact, extending its service life, and ensuring no gaps between the frame 31 and the support legs 32, facilitating user cleaning. Furthermore, the integrally formed frame 31 and support legs 32 simplify the manufacturing process and assembly steps of the metal grill 30, reducing costs.

[0053] In the illustrated embodiment, the frame 31 includes a support rod 311 located on the outer ring and multiple connecting rods 312. Both ends of the multiple connecting rods 312 are connected to the support rod 311, and adjacent connecting rods 312 are spaced apart. Parts of the connecting rods 312 are bent downwards to form legs 32. An insulating element 33 is provided on the support rod 311. The support rod 311 connects and supports each connecting rod 312. Since the support rod 311 is located on the periphery of the metal grill 30, it is the position where the metal grill 30 is most likely to contact the inner wall of the inner liner 10. Therefore, the insulating element 33 is provided on the support rod 311 to ensure that no matter how the metal grill 30 is placed, the frame 31 will not contact the inner wall of the inner liner 10, achieving precise protection. The legs 32, formed by bending parts of the connecting rods 312 downwards, ensure the strength and stability of the metal grill 30, facilitate processing, and reduce the number of parts, thus reducing the overall weight of the metal grill 30. Of course, the frame 31 and the legs 32 can also be other structures. For example, the entire frame 31 can be formed by bending a support rod 311 or a connecting rod 312, and part of the frame 31 can be bent downwards to form the legs 32.

[0054] In other embodiments, the frame 31 and the support leg 32 can also be processed separately and fixed by welding, gluing, pressing, interference fit, snap-fit, threaded connection, etc., as long as the stability and reliability of the connection between the two can be ensured. This utility model embodiment does not impose specific limitations here.

[0055] like Figures 1 to 2As shown, in one embodiment, the support plate 20 is made of microcrystalline glass. Microcrystalline glass ensures the normal operation of the microwave function and is resistant to high temperatures, has high strength, and is easy to clean, thereby ensuring the safety of the support plate 20 and extending its service life. Of course, in other embodiments, the support plate 20 can also be made of ceramic, borosilicate glass, or other insulating materials suitable for microwave cooking equipment; this embodiment of the present invention does not impose specific limitations.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
