[0044] The protective cover 10 according to the embodiments of the utility model is described below with reference to the drawings.

[0045] As Figure 1 As shown in the drawings, the protective cover 10 according to the embodiments of the utility model, the protective cover 10 is used for covering the heating component 30 of the cooking device 100, the protective cover 10 has a length direction and a side edge 101 at both ends of the length direction, a plurality of through holes 102 arranged in an array are formed on the protective cover 10, the size of the through hole 102 in the length direction is greater than the size in the extension direction of the side edge 101, and the size of the through hole 102 in the extension direction of the side edge 101 is greater than or equal to 6mm.

[0046] The material of the protective cover 10 can be but not limited to metal material or non-metal material, the metal material can include but not limited to low carbon steel and the like, the non-metal material can include but not limited to quartz glass, ceramic and the like. Among them, the length direction of the protective cover 10 can refer to Figure 1 And Figure 2 The left and right direction.

[0047] The side edge 101 can refer to the edge line of the protective cover 10 at both ends of the length direction, according to the shape of the protective cover 10, the shape of the side edge 101 is also different. The shape of the side edge 101 can include but not limited to arc, U-shaped or V-shaped and the like. The extension direction of the side edge 101 can refer to the direction along the shape of the side edge 101, for example, the side edge 101 is arc-shaped, the extension direction of the side edge 101 can be arc direction.

[0048] Since the size of the through hole 102 in the length direction is greater than the size in the extension direction of the side edge 101, the through hole 102 is a rectangular hole, and the size of the through hole 102 in the extension direction of the side edge 101 is greater than or equal to 6mm, so in the extension direction of the side edge 101, the through hole 102 can be arranged in a smaller number, which is beneficial to make the hole area of the through hole 102 relatively large, that is, the plurality of through holes 102 arranged in an array on the protective cover 10 are all large size holes. This scheme is beneficial to reduce the shielding area of the protective cover 10 to the heating component 30.

[0049] According to the protective cover 10, the number of through holes 101 can be arranged less and the size is set larger in the extension direction of the side edge 101, which is beneficial to lightweight design of the protective cover 10, saves materials, and reduces manufacturing cost. Since the through hole 102 is a rectangular hole, and the size of the through hole 102 in the extension direction of the side edge 101 is greater than or equal to 6mm, the through hole 102 has good light transmittance, which can reduce the shielding area of the protective cover 10 to the heating component 30, reduce the influence of the heat radiation of the heating component 30, and the heat radiation of the heating component 30 can pass through the protective cover 10 more, which is beneficial to improve the heating efficiency of the heating component 30 to the food material.

[0050] In some embodiments of the utility model, as shown in Figure 3 The size of the through hole 102 in the extension direction of the side edge 101 is less than or equal to 16mm.

[0051] The size of the through hole 102 in the extension direction of the side edge 101 can be L1, that is, L1 can be but not limited to 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm and the like. Among them, the size L1 of the plurality of through holes 102 in the extension direction of the side edge 101 can be the same or different.

[0052] It can be understood that by setting the size of the through hole 102 in the extension direction of the side edge 101 in the above range, the through hole 102 can have a larger size, and it is also beneficial to make the protective cover 10 as a whole have stronger rigidity and strength.

[0053] In some embodiments of the utility model, the size of the through hole 102 in the length direction is greater than or equal to 35mm.

[0054] The length direction can refer to the length direction of the protective cover 10. It can be understood that by setting the size of the through hole 102 in the length direction to be greater than or equal to 35mm, and combining the width size of the through hole 102 as described above, the size of the through hole 102 is set in the above range to have good light transmittance, and the weight reduction effect of the protective cover 10 is also good.

[0055] In some embodiments of the utility model, as shown in Figure 2 The size of the through hole 102 in the length direction is less than or equal to 75mm. The size of the through hole 102 in the length direction can be L2, that is, L2 can be but not limited to 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm and the like. Among them, the size of the plurality of through holes 102 in the length direction can be the same or different.

[0056] In the above technical solution, in the case of knowing the width dimension of the through hole 102, by setting the length dimension of the through hole 102 in the above range, the through hole 102 can have a suitable size, further improving the light transmittance of the through hole 102, and reducing the shielding area of the protective cover 10 to the heat generating component 30.

[0057] In some embodiments of the present application, as shown in Figure 1 , Figure 2 and Figure 4 , the protective cover 10 includes a main body part 11 and a hook part 12, and the main body part 11 is formed with a through hole 102; the hook part 12 is provided at both ends of the main body part 11 in the length direction.

[0058] The main body part 11 can refer to the main structure of the protective cover 10, and the shape can be, but is not limited to, arc shape, U shape or V shape, etc. For example, as shown in Figure 1 , the shape of the main body part 11 is arc shape.

[0059] The hook part 12 can be provided at one or more ends of the main body part 11 in the length direction. For example, the hook part 12 is provided at one end of the main body part 11 on the left and right, or, as shown in Figure 1 and Figure 4 , the hook part 12 is provided at two ends of the main body part 11 in the front and back directions.

[0060] In the above technical solution, the protective cover 10 can be quickly installed and fixed through the hook part 12, and the installation method using such a hook part 12 is relatively simple, easy to install or disassemble, and also facilitates later maintenance and repair.

[0061] In some embodiments of the present application, as shown in Figure 1 and Figure 3 , the main body part 11 is in circular arc shape, and the diameter of the main body part 11 is D, wherein 30mm≤D≤40mm.

[0062] D can be, but is not limited to, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 35mm, 37mm, 38mm, 39mm, 40mm, etc.

[0063] In the above technical solution, by setting the diameter of the main body part 11 in the above range, the side of the main body part 11 close to the heat generating component 30 can form a larger space, and the distance between the main body part 11 and the heat generating component 30 is also relatively large, which can avoid the user's finger from passing through the through hole 102 and contacting the heat generating component 30 in case of misoperation, thereby preventing the user from being injured due to misoperation when using the cooking device 100.

[0064] In some embodiments of the present application, as shown in Figure 5As shown, the hook portion 12 comprises a vertical rod 121 connected to the main body portion 11 and a hook 122 comprising 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 being connected to two ends of the arc-shaped portion 1223, and the first inclined rod 1221 being connected to the vertical rod 121 and the distance between the first inclined rod 1221 and the second inclined rod 1222 gradually increasing in a direction away from the arc-shaped portion 1223.

[0065] In the above structure, the first inclined rod 1221 is inclined to a side away from the main body portion 11 relative to the vertical rod 121, which can make the hook portion 12 as a whole extend outward relative to the main body portion 11, reduce the influence of the main body portion 11 on the hook portion 12, provide more space for the hook portion 12, and facilitate installation or disassembly. The first inclined rod 1221 and the second inclined rod 1222 can form an inverted conical structure, which can make the opening of the hook portion 12 designed larger, facilitating the hook portion 12 to be hooked on a hole or a ring structure. Since the arc-shaped portion 1223 is an arc-shaped structure, it is convenient to be hooked on a hole or a ring structure, improves installation stability, and can be connected to the first inclined rod 1221 and the second inclined rod 1222 in a smooth transition, reducing stress concentration and improving the reliability of the hook portion 12 as a whole.

[0066] In some embodiments of the present application, as shown in Figure 5 The angle between the first inclined rod 1221 and the plumb line is θ1, and 93 degrees ≤ θ1 ≤ 98 degrees; and the angle between the second inclined rod 1222 and the horizontal line is θ2, and 95 degrees ≤ θ2 ≤ 105 degrees.

[0067] θ1 can be, but is not limited to, 93 degrees, 94 degrees, 95 degrees, 96 degrees, 97 degrees, 98 degrees, etc.

[0068] 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.

[0069] 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 an appropriate inclination angle, facilitating installation or disassembly of the hook portion 12.

[0070] In some embodiments of the present application, as shown in Figure 5As shown in the drawings, the size of the hook 122 in the length direction of the protective cover 10 is H1, wherein 8mm≤H1≤15mm. That is, H1 can be, but is not limited to, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, and the like. By setting the size of the hook 122 in the length direction of the protective cover 10 within the above range, the hook 122 can be in an appropriate size, facilitating the installation or removal of the hook 122.

[0071] In some embodiments of the present application, as shown in the drawings, Figure 5 As shown in the drawings, the second inclined rod 1222 has a first end face away from the arc-shaped part 1223, the arc-shaped part 1223 has a second end face away from the first inclined rod 1221 and the second inclined rod 1222, and the distance between the second end face and the first end face is H2, wherein 3mm≤H2≤10mm. That is, H2 can be, but is not limited to, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, and the like. The second inclined rod 1222 has a suitable height by adopting the above structure, facilitating the installation or removal of the hook 122.

[0072] In some embodiments of the present application, as shown in the drawings, Figure 3 As shown in the drawings, the protective cover 10 is configured to have a tangent line F1 with the top of the main body part 11 and the top of the heating component 30 located at the side edge 101, and the included angle between the tangent line F1 and the horizontal line is θ3, wherein 40 degrees≤θ3≤60 degrees.

[0073] 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, and the like.

[0074] In the above technical solution, if θ3 is less than 40 degrees, the distance between the top of the main body part 11 and the top of the heating component 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, resulting in a relatively small size of the hook part 12, which is not convenient for installing or removing the hook part 12. If θ3 is greater than 60 degrees, the distance between the top of the main body part 11 and the top of the heating component 30 is relatively large, which increases the probability of the user's fingers entering from the top of the main body part 11 to touch the heating component 30 when misoperating, easily causing safety hazards, and when using a test probe for testing, the test probe is also easy to enter from the top of the main body part 11 to touch the heating component 30 when misoperating, which is not conducive to ensuring the safety of the heating component 30. That is, by configuring the protective cover 10 as the above structure, the heating component 30 can be prevented from being touched, and the safety of the cooking device 100 can be improved.

[0075] In some embodiments of the present application, as shown in the drawings, Figure 1 and Figure 3As shown, the main body 11 comprises a plurality of first rods 111 and a plurality of second rods 112, the plurality of first rods 111 are arranged in the direction of the side edge 101 and each first rod 111 extends in the length direction, the plurality of second rods 112 are arranged in the length direction and each second rod 112 extends in the direction of the side edge 101, and any two adjacent first rods 111 and second rods 112 jointly define a through hole 102.

[0076] In the above technical solution, the first rod 111 can be a long rod, the second rod 112 can be a short rod, and the main body 11 can be a frame structure composed of a plurality of thin rods. Since the size of the through hole 102 is relatively large, the protective cover 10 formed by the above scheme uses a relatively small number of rods. When different rods are connected (for example, connected by welding or bundling), the operation steps are relatively small, the manufacturing process can be simplified, the rod material can be reduced, and the cost can be reduced.

[0077] The number of first rods 111 and second rods 112 can be set as needed. Optionally, the number of first rods 111 can be four to six, and the number of second rods 112 can be seven to nine.

[0078] Exemplarily, as shown in the drawings, Figure 1 The first rod 111 can be four first rods 111 and eight second rods 112, the second rod 112 can be curved into an arc shape and arranged in the left-right direction, the four first rods 111 are lapped on the arc-shaped second rod 112 and welded with the second rod 112, and any two adjacent first rods 111 and adjacent second rods 112 jointly define a through hole 102.

[0079] In the above scheme, the material of the first rod 111 and the second rod 112 can include but is not limited to metal material or non-metal material. The metal material can include but is not limited to low-carbon steel and the like. The non-metal material can include but is not limited to quartz glass, ceramic and the like.

[0080] In some embodiments of the utility model, the first rod 111 and the second rod 112 are round rods, and the diameter is 1.5mm-3mm. That is, the diameter of the first rod 111 and the second rod 112 can be but is not limited to 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm, 2.7mm, 2.8mm, 3.0mm and the like. The diameter of the first rod 111 and the second rod 112 can be equal or not equal, which is not limited here.

[0081] In some embodiments of the utility model, the surface of the first rod member 111 and the second rod member 112 is provided with an anti-rust coating. The anti-rust coating can be provided on the first rod member 111 and the second rod member 112 by means including but not limited to electroplating, coating and the like. Alternatively, the first rod member 111 and the second rod member 112 can be made of anti-rust rod material. This scheme also has the anti-rust effect, prolongs the service life of the protective cover 10, reduces the processing procedures and reduces the manufacturing cost.

[0082] In some embodiments of the utility model, as shown in Figure 6 The protective cover 10 is integrally formed by a plate member and has a through hole 102. It can be understood that the protective cover 10 can be directly processed from a large plate, and the forming method of the protective cover 10 can include but is not limited to stamping forming, bending forming or hot pressing forming. The through hole 102 can be formed by means including but not limited to blanking.

[0083] In the above technical solution, the protective cover 10 adopts the above structure, can be manufactured and formed at one time, can simplify the manufacturing process, reduce the manufacturing cost, and because the protective cover 10 is an integrally formed member, the protective cover 10 has high rigidity and strength, can improve the reliability of the protective cover 10 and prolong the service life of the protective cover 10.

[0084] In some embodiments of the utility model, when the protective cover 10 is integrally formed by a plate member, the thickness of the plate is 0.5mm-1.5mm. That is, the thickness of the plate can be but is not limited to 0.5mm, 0.7mm, 0.9mm, 1.1mm, 1.3mm, 1.5mm and the like. By setting the thickness of the plate member for manufacturing the protective cover 10 in the above range, the material consumption can be reduced on the basis of ensuring the rigidity and strength of the protective cover 10, which is beneficial to reducing the cost.

[0085] Next, a specific embodiment of the protective cover 10 of the utility model will be described with reference to the drawings.

[0086] As Figures 1 to 7 , the protective cover 10 includes a main body part 11 and a hook part 12, the main body part 11 has a plurality of through holes 102 arranged in an array, and the hook part 12 is arranged at both ends of the main body part 11 in the length direction.

[0087] The protective cover 10 has a length direction and side edges 101 at both ends of the length direction. The main body 11 includes four first rods 111 and eight second rods 112. The four first rods 111 are spaced apart along the side edges 101, and each first rod 111 extends along the length direction.
