Description

Technical Field

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

[0002] Most ovens on the market currently use heating elements (e.g., heating tubes). According to the mechanical strength requirements of the national standard GB4706.14, ovens using visible light heating elements encapsulated in glass tubes, if installed on the top of the oven and accessible by the No. 41 test probe specified in GB16842, require an impact test with an energy of 0.7J. Typically, considering the impact sensitivity of heating elements, protective rods or covers are added to the glass tubes to meet safety regulations. However, existing protective rods or covers have complex structures, require more materials, resulting in higher costs. Furthermore, the large coverage area of ​​these protective rods or covers can easily affect the heating efficiency of the heating element on the food. Utility Model Content

[0042] Furthermore, features specified as "first" or "second" may explicitly or implicitly include one or more of the same feature, used to distinguish and describe features, without any order or distinction of importance.

[0043] In the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] The protective cover 10 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0046] like Figures 1 to 3 As shown, a protective cover 10 according to an embodiment of the present utility model is used to cover the heating element 30 of the cooking device 100. The protective cover 10 is integrally formed by a plate and has a plurality of through holes 101 arranged in an array. The minimum distance between the edge contours of any two adjacent through holes 101 is less than or equal to 3mm.

[0047] The protective cover 10 can be directly formed from a large sheet of material, and burrs can be removed by grinding. The forming method of the protective cover 10 can include, but is not limited to, stamping, bending, or hot pressing. The material of the protective cover 10 can be, but is not limited to, metal or non-metal materials. Metal materials can include, but are not limited to, low-carbon steel, and non-metal materials can include, but are not limited to, quartz glass, ceramics, etc.

[0048] The minimum distance between any two adjacent edge contours of the multiple through holes 101 can be L1, that is, L1 can be, but is not limited to, 3mm, 2.5mm, 2mm, 1.5mm, 1mm, etc. By setting the minimum distance between any two adjacent edge contours of the multiple through holes 101 to less than or equal to 3mm, more through holes 101 can be arranged on the protective cover 10, and their distribution can be more dense, resulting in a larger area of ​​the hollowed-out area on the protective cover 10. The through holes 101 can be, but are not limited to, circular holes, square holes, elliptical holes, hexagonal holes, etc., without specific limitations.

[0049] According to the embodiment of the present invention, the protective cover 10 has a simple manufacturing process, which can reduce manufacturing costs, achieve lightweight design, save materials, and reduce material costs. Moreover, the protective cover 10 is provided with a plurality of through holes 101 arranged in an array. The minimum distance between the edge contours of any two adjacent through holes 101 is less than or equal to 3mm. As a result, the sum of the hole areas of the plurality of through holes 101 is relatively large, which can reduce the shielding area of ​​the heating element 30 by the protective cover 10, thereby reducing the impact on the heat radiation of the heating element 30. The heat radiation of the heating element 30 can pass through the protective cover 10 more, which is beneficial to improving the heating efficiency of the heating element 30 on the food.

[0050] In some embodiments of this utility model, the minimum distance between the edge contours of any two adjacent through holes 101 is greater than or equal to 0.5 mm.

[0051] Based on the preceding text, L1 can be as small as 0.5mm. It is understandable that if the minimum distance L1 between any two adjacent edge contours of multiple through holes 101 is less than 0.5mm, the width of the plate portion between the two adjacent through holes 101 is relatively small, and the whole is relatively brittle, with a higher risk of breakage.

[0052] In other words, the above solution can make the plate portion between any two adjacent through holes 101 have suitable rigidity and strength, thereby preventing the plate portion between two adjacent through holes 101 from being prone to breakage due to its small width, which is beneficial to improving the overall reliability of the protective cover 10.

[0053] In some embodiments of this utility model, such as Figures 1 to 3 As shown, a filling hole 102 is provided between any four adjacent through holes 101.

[0054] It is understandable that among the multiple through holes 101 arranged in an array, there will still be a large blank area between four adjacent through holes 101. Therefore, by further providing filling holes 102 in this blank area, the shielding area of ​​the heating element 30 by the protective cover 10 can be further reduced, and more heat radiation from the heating element 30 can pass through the protective cover 10, thereby further improving the heating efficiency of the heating element 30 on the food. The filling holes 102 can also be, but are not limited to, circular holes, square holes, elliptical holes, hexagonal holes, etc. The shapes of the filling holes 102 and the through holes 101 can be the same or different, and no specific limitation is made in this embodiment.

[0055] In some embodiments of this utility model, such as Figure 3 As shown, the minimum distance between the edge profile of the filling hole 102 and the edge profile of the adjacent through hole 101 is less than or equal to 3 mm.

[0056] The minimum distance between the edge contour of the filling hole 102 and the edge contour of the adjacent through hole 101 can be L2, that is, L2 can be 3mm, 2.5mm, 2mm, 1.5mm, 1mm, etc.

[0057] By setting the minimum distance between the edge contour of the filling hole 102 and the edge contour of the adjacent through hole 101 within the aforementioned range, the filling hole 102 can be made larger in the blank area defined between the four adjacent through holes 101. This results in a larger sum of the hole areas of all through holes 101 and all filling holes 102, thereby further reducing the shielding area of ​​the heating element 30 by the protective cover 10. As a result, more heat radiation from the heating element 30 passes through the protective cover 10, which further improves the heating efficiency of the heating element 30 on the food.

[0058] In some embodiments of this utility model, the minimum distance between the edge contour of the filling hole 102 and the edge contour of the adjacent through hole 101 is greater than or equal to 0.5 mm.

[0059] Based on the preceding text, this means that L2 can be as small as 0.5mm. It is understandable that if the minimum distance L2 between the edge contour of the filling hole 102 and the edge contour of the adjacent through hole 101 is less than 0.5mm, the width of the plate portion between the filling hole 102 and the through hole 101 is relatively small, making the plate more brittle and increasing the risk of breakage.

[0060] In other words, the above solution can give the plate portion between the filling hole 102 and the through hole 101 suitable rigidity and strength, thereby preventing the plate portion between the filling hole 102 and the through hole 101 from being prone to breakage due to its small width, which is beneficial to improving the overall reliability of the protective cover 10.

[0061] In some embodiments of the present invention, Figure 3 As shown, the through hole 101 and the filling hole 102 are circular holes, and the diameter of the filling hole 102 is smaller than the diameter of the through hole 101. The diameter of the through hole 101 is D, where 5mm≤D≤18mm.

[0062] Since the through hole 101 and the filling hole 102 are circular holes, and the diameter of the filling hole 102 is smaller than the diameter of the through hole 101, this scheme can make the local structure formed by four adjacent through holes 101 and filling holes 102 more compact, thereby arranging more densely on the protective cover 10, which is beneficial to further increase the sum of the hole areas of the through holes 101 and filling holes 102.

[0063] D can be, but is not limited to, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, etc. By setting the diameter of the through hole 101 within the above range, the through hole 101 can have a suitable diameter, which facilitates the setting of the through hole 101 on the surface of the protective cover 10, and also helps to enhance the light transmittance of the through hole 101 and reduce the shading area of ​​the protective cover 10 on the heat-generating component 30.

[0064] In some embodiments of the present invention, Figures 1 to 3 As shown, the protective cover 10 has a length direction and first edges 103 at both ends in the length direction. Among the multiple through holes 101 arranged in an array, the through holes 101 at both ends in the length direction are arranged adjacent to the first edges 103.

[0065] The length direction of the protective cover 10 can refer to Figures 1 to 3 The left and right directions. The first edge 103 can refer to the short edges of the protective cover 10 located at both ends in the length direction. Depending on the shape of the protective cover 10, the first edge 103 can be, but is not limited to, curved, U-shaped, V-shaped, etc. For example, as Figure 1 As shown, the protective cover 10 is arc-shaped, and the first edge 103 is arc-shaped.

[0066] It is understandable that among the multiple through holes 101 arranged in an array, the two rows of through holes 101 located at both ends of the length direction are close to the first edge 103. This allows the multiple through holes 101 to be distributed more densely in the length direction of the protective cover 10, which can increase the number of through holes 101 and also helps to reduce the shielding area of ​​the protective cover 10 on the heat-generating component 30.

[0067] In some embodiments of the present invention, Figures 1 to 3 As shown, the protective cover 10 has a width direction and second edges 104 located at both ends in the width direction. Among the multiple through holes 101 arranged in an array, the through holes 101 located at both ends in the width direction are arranged adjacent to the second edges 104.

[0068] The width direction of the protective cover 10 can refer to Figure 1 , Figure 2 and Figure 3 The front and rear directions. The second edge 104 can refer to the long side lines of the protective cover 10 located at both ends in the width direction.

[0069] It is understandable that among the multiple through holes 101 arranged in an array, the two rows of through holes 101 located at both ends in the width direction are close to the second edge 104. This allows the multiple through holes 101 to be distributed more densely in the width direction of the protective cover 10, which can also increase the number of through holes 101 and help reduce the shielding area of ​​the protective cover 10 on the heat-generating component 30.

[0070] In some embodiments of this utility model, such as Figures 1 to 4 As shown, the protective cover 10 has a length direction. The protective cover 10 includes a main body 11 and a hook part 12. A through hole 101 is formed on the main body 11, and the hook part 12 is provided at both ends of the main body 11 in the length direction.

[0071] The main body 11 can refer to the main structure of the protective cover 10, and can be, but is not limited to, an arc-shaped plate, a U-shaped plate, or a V-shaped plate, etc. For example, such as Figure 1 As shown, the main body 11 is an arc-shaped plate.

[0072] One or more hook portions 12 may be provided at both ends of the main body portion 11 along its length. For example, one hook portion 12 may be provided at each of the left and right ends of the main body portion 11, or, as... Figure 1 and Figure 2 Two hooks 12 are provided at the left and right ends of the main body 11 along the front-back direction.

[0073] In the above technical solution, the protective cover 10 can be quickly installed and fixed through the hook part 12. The installation method using this hook part 12 is relatively simple, easy to install or disassemble, and also beneficial to later inspection and maintenance.

[0074] In some embodiments of this utility model, such as Figure 1 As shown, the main body 11 is arc-shaped, and the diameter of the main body 11 is D, where 30mm≤D≤40mm.

[0075] D can be, but is not limited to, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 37mm, 38mm, 39mm, 40mm, etc.

[0076] In the above technical solution, by setting the diameter of the main body 11 within the above range, a larger space can be formed on the side of the main body 11 close to the heating element 30, and the distance between the main body 11 and the heating element 30 is also relatively large. This can prevent the user's finger from passing through the through hole 101 and contacting the heating element 30 in case of accidental operation, thereby preventing the user from being injured due to accidental operation when using the cooking device 100.

[0077] In some embodiments of this utility model, such as Figure 4 and Figure 5As shown, the hook portion 12 includes a vertical rod 121 and a hook 122. The vertical rod 121 is connected to the main body portion 11. The hook 122 includes a first inclined rod 1221, a second inclined rod 1222, and an arc-shaped portion 1223. The first inclined rod 1221 and the second inclined rod 1222 are connected to the two ends of the arc-shaped portion 1223. The first inclined rod 1221 is connected to the vertical rod 121, and the distance between the first inclined rod 1221 and the second inclined rod 1222 gradually increases in the direction away from the arc-shaped portion 1223.

[0078] In the above structure, the first diagonal bar 1221 is inclined away from the main body 11 relative to the vertical bar 121, which allows the hook part 12 to extend outward relative to the main body 11, reducing the influence of the main body 11 on the hook part 12 and providing more space for the hook part 12, facilitating installation or disassembly. An inverted conical structure can be formed between the first diagonal bar 1221 and the second diagonal bar 1222. This structure allows for a larger opening in the hook part 12, making it easier to hook onto holes or rings. Since the arc-shaped part 1223 is arc-shaped, it is easy to hook onto holes or rings, improving installation stability. It also smoothly transitions with the first diagonal bar 1221 and the second diagonal bar 1222, reducing stress concentration and improving the overall reliability of the hook part 12.

[0079] In some embodiments of the present invention, Figure 5 As shown, the angle between the first inclined rod 1221 and the vertical line is θ1, where 93 degrees ≤ θ1 ≤ 98 degrees; the angle between the second inclined rod 1222 and the horizontal line is θ2, where 95 degrees ≤ θ2 ≤ 105 degrees.

[0080] θ1 can be, but is not limited to, 93 degrees, 94 degrees, 95 degrees, 96 degrees, 97 degrees, 98 degrees, etc.

[0081] θ2 can be, but is not limited to, 95 degrees, 96 degrees, 97 degrees, 98 degrees, 99 degrees, 100 degrees, 101 degrees, 102 degrees, 103 degrees, 104 degrees, 105 degrees, etc.

[0082] In the above technical solution, by setting the angle between the first inclined rod 1221 and the plumb line, and the angle between the second inclined rod 1222 and the horizontal line within the above range, the first inclined rod 1221 and the second inclined rod 1222 can be at a suitable tilt angle, which facilitates the installation or removal of the hook part 12.

[0083] In some embodiments of the present invention, Figure 5As shown, the dimension of hook 122 along the length of protective cover 10 is H1, where 8mm ≤ H1 ≤ 15mm. That is, H1 can be, but is not limited to, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc. By setting the dimension of hook 122 along the length of protective cover 10 within the above range, hook 122 can be made to a suitable size, facilitating the installation or removal of hook 122.

[0084] In some embodiments of this utility model, such as Figure 5 As shown, the second diagonal bar 1222 has a first end face away from the arc-shaped portion 1223, and the arc-shaped portion 1223 has a second end face away from the first diagonal bar 1221 and the second diagonal bar 1222. The distance between the second end face and the first end face is H2, where 3mm ≤ H2 ≤ 10mm. That is, H2 can be, but is not limited to, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. With the above structure, the second diagonal bar 1222 has a suitable height, which facilitates the installation or removal of the hook 122.

[0085] In some embodiments of this utility model, such as Figure 6 As shown, the protective cover 10 is configured such that the tangent F1 between the top of the main body 11 and the top of the heating element 30 is perpendicular to the horizontal line, and the angle between the tangent F1 and the horizontal line is θ3, wherein 40 degrees ≤ θ3 ≤ 60 degrees.

[0086] θ3 can be, but is not limited to, 40 degrees, 42 degrees, 44 degrees, 46 degrees, 48 ​​degrees, 50 degrees, 52 degrees, 54 degrees, 56 degrees, 58 degrees, 60 degrees, etc.

[0087] In the above technical solution, if θ3 is less than 40 degrees, the distance between the top of the main body 11 and the top of the heating element 30 is relatively close, and the distance between the protective cover 10 and the cavity wall of the cooking cavity 20a is also relatively small. This results in a smaller hook portion 12, making it inconvenient to install or remove the hook portion 12. If θ3 is greater than 60 degrees, the distance between the top of the main body 11 and the top of the heating element 30 is relatively large. This increases the probability that the user's finger will accidentally enter from the top of the main body 11 and touch the heating element 30, which can easily lead to safety hazards. Moreover, when using a test probe, the test probe can also easily enter from the top of the main body 11 and touch the heating element 30 during accidental operation, which is not conducive to ensuring the safety of the heating element 30. In other words, by configuring the protective cover 10 with the above structure, the heating element 30 can be prevented from being touched, and the safety of the cooking device 100 can be improved.

[0088] In some embodiments of this utility model, the thickness of the protective cover 10 is 0.5mm to 2mm. The thickness of the protective cover 10 can refer to the thickness of the plate forming the protective cover 10, and the thickness of the plate can be, but is not limited to, 0.5mm, 0.7mm, 0.9mm, 1.0mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm, etc.

[0089] In the above technical solution, by setting the thickness of the protective cover 10 within the above range, the protective cover 10 can have high rigidity and strength, improve the reliability of the protective cover 10, and also save materials and reduce costs.

[0090] In some embodiments of this utility model, the surface of the protective cover 10 is provided with an anti-rust coating. By providing the anti-rust coating, the protective cover 10 can be rust-proofed, thus extending its service life. The anti-rust coating can be applied to the surface of the protective cover 10 by methods including, but not limited to, electroplating, coating, etc.

[0091] Alternatively, the plate material used for the protective cover 10 can also be a rust-proof plate material. This solution can also play a rust-proof role, extend the service life of the protective cover 10, and reduce processing steps and manufacturing costs.

[0092] A specific embodiment of the protective cover 10 of this utility model is described below with reference to the accompanying drawings.

[0093] like Figures 1 to 6 As shown, the protective cover 10 is integrally formed from a low-carbon steel plate and has multiple circular through holes 101 arranged in an array. The minimum distance between the edge contours of any two adjacent through holes 101 is less than or equal to 3 mm and greater than or equal to 0.5 mm.

[0094] A circular filling hole 102 is provided between any four adjacent through holes 101. The minimum distance between the edge contour of the filling hole 102 and the edge contour of the adjacent through hole 101 is less than or equal to 3 mm and greater than or equal to 0.5 mm. The diameter of the filling hole 102 is smaller than the diameter of the through hole 101, and the diameter of the through hole 101 is D, where 5 mm ≤ D ≤ 18 mm.

[0097] In the above embodiments, compared to conventional protective covers composed of multiple long and short wires, the protective cover 10 of this invention has a simpler structure, significantly reduces the amount of low-carbon steel used, and substantially lowers manufacturing costs. Simultaneously, the reduced shielding area effectively improves the heating efficiency of the heating element. Specifically, the amount of low-carbon steel used can be reduced by 24.6%, and manufacturing costs can be reduced by 18%. Furthermore, the shielding area of ​​the heating element 30 by the protective cover 10 can be reduced by 15.4%, thereby increasing the heating efficiency of the heating element 30 by 2-4%.

[0098] like Figure 7 As shown, a cooking device 100 according to an embodiment of the present invention includes: a cooking body 20, a heating element 30, and a protective cover 10. The cooking body 20 has a cooking cavity 20a; the heating element 30 is disposed in the cooking cavity 20a; the protective cover 10 is as described in any of the preceding embodiments, the protective cover 10 is located in the cooking cavity 20a and connected to the cooking body 20, and the protective cover 10 covers the heating element 30.

[0099] In the above embodiments, the cooking device 100 can be, but is not limited to, an oven, air fryer, electric grill, electric baking pan, etc. The cooking body 20 can refer to the main structure including the housing. The cooking cavity 20a can refer to the space used for holding and processing food ingredients.

[0100] The heating element 30 can refer to a component capable of radiating heat, and can be, but is not limited to, a heating tube, heating wire, etc. The number of heating elements 30 can be one or more, and correspondingly, the number of protective covers 10 is equal to and corresponds one-to-one with the number of heating elements 30. For example... Figure 7 As shown, there can be two heating elements 30, and each heating element 30 is provided with a protective cover 10.

[0101] It should be noted that other components and operations of the cooking apparatus 100 of this utility model embodiment are known to those skilled in the art and will not be described in detail here. For example, when the cooking apparatus 100 is an oven, the components and operations of the oven other than the protective cover 10 are known to those skilled in the art, and can be found in ovens of related technologies, which will not be repeated here.

[0102] According to the embodiment of the present utility model, the cooking device 100 has a simple manufacturing process for the protective cover 10, which can reduce manufacturing costs and thus reduce the overall manufacturing cost of the cooking device 100. The protective cover 10 covers a small area of ​​the heating element 30, which is beneficial to improve the heating efficiency of the heating element 30 on the food, thereby improving the cooking effect of the cooking device 100.

[0103] In some embodiments of the present invention, Figure 7 As shown, the heating element 30 is located on the top of the cooking cavity 20a, and the protective cover 10 is located below the heating element 30.

[0104] Since food needs to be cooked inside the cooking cavity 20a, placing the heating element 30 at the top of the cooking cavity 20a reduces interference with the food and facilitates proper placement of the food within the cooking cavity 20a. The protective cover 10, located below the heating element 30, covers the area below the heating element 30, preventing accidental activation of the heating element 30 by the user's hand when it enters the cooking cavity 20a, thus improving user safety.
