[0044] Combination Figure 5 , Fig. 9 , Fig.10 , Figures 14 to 16As shown, in some embodiments of the present application, a portion of the support plates are located on the side of the central portion of the heating element away from the cooking cavity 21 and are provided with a second reflecting portion 221, and at least a portion of the structure of the second reflecting portion 221 is arranged at an angle to the plate surface of the support plate where the second reflecting portion 221 is located, and along a direction perpendicular to the support plate where the second reflecting portion 221 is located, the projection of the heating element on the support plate at least partially overlaps with the projection of the second reflecting portion 221 on the support plate.

[0045] In some embodiments of the present application, the heating element includes a first heating element 31 and a second heating element 32, and the first heating element 31 and the second heating element 32 are respectively arranged on the upper and lower sides of the cooking cavity 21. When the food is cooked in the cooking cavity 21, it can be placed between the first heating element 31 and the second heating element 32, so that the upper and lower surfaces of the food can be heated by the first heating element 31 and the second heating element 32 respectively. Among them, the top support plate 22 is located on the side of the first heating element 31 away from the middle of the cooking cavity 21, and the bottom support plate 23 is located on the side of the second heating element 32 away from the middle of the cooking cavity 21. The top support plate 22 is provided with a second reflecting portion 221 arranged opposite to the first heating element 31, and / or the bottom support plate 23 is provided with a second reflecting portion 221 arranged opposite to the second heating element 32. For the convenience of description, the embodiments of the present application are described by taking the example that the top support plate 22 is provided with the second reflecting portion 221.

[0046] The heat emitted from the side surface of the first heating element 31 facing the food can directly act on the food, and the heat emitted from the other side surface of the first heating element 31 facing away from the food, that is, the other side surface of the first heating element 31 facing the top support plate 22, needs to act on the top support plate 22 first, and then act on the food after being reflected by the top support plate 22. When the surface of the top support plate 22 is perpendicular to the projection direction of the heat emitted by the first heating element 31, the heat reflected by the top support plate 22 returns along the original path, and is thus blocked by the first heating element 31. Therefore, in order to change the projection direction of the heat reflected by the top support plate 22, a second reflecting portion 221 is provided on a portion of the top support plates 22 located on the side of the middle portion of the first heating element 31 away from the cooking cavity 21, and at least a portion of the structure of the second reflecting portion 221 is arranged at an angle to the plate surface of the top support plate 22, and along a direction perpendicular to the plate surface of the top support plate 22, the projection of the first heating element 31 on the top support plate 22 at least partially overlaps with the projection of the second reflecting portion 221 on the top support plate 22.

[0047] The heat emitted by the first heating element 31 toward the top support plate 22 acts on the top support plate 22. Part of the heat flows to the top support plate 22 in a direction that is not perpendicular to the plate surface of the top support plate 22, and is reflected by the top support plate 22 in a direction that is angled with the original flow direction to the inside of the cooking cavity 21, thereby reducing the shielding of the reflected heat by the first heating element 31. The other part of the heat flows to the top support plate 22 in a direction perpendicular to the plate surface of the top support plate 22. Since the projection of the first heating element 31 on the top support plate 22 and the projection of the second reflecting portion 221 on the top support plate 22 at least partially overlap in the direction perpendicular to the plate surface of the top support plate 22, the other part of the heat flowing to the top support plate 22 in a direction perpendicular to the plate surface of the top support plate 22 acts on the second reflecting portion 221, and under the action of the second reflecting portion 221, flows to the inside of the cooking cavity 21 in a direction that is angled with the original flow direction, thereby reducing the shielding of the reflected heat by the first heating element 31, thereby allowing the reflected heat to act more on the food in the cooking cavity 21, thereby improving the cooking efficiency of the cooking device 1. At the same time, the reflected heat can act on the food at different angles, thereby heating different surfaces of the food, thereby improving the cooking efficiency and cooking effect of the food.

[0048] It should be noted that the angle in this application refers to the angle range between the two being 0° and 180°, which does not include 0° and 180°.

[0049] Combination Figure 5 , Fig. 9 , Fig.10 , Figures 14 to 16 As shown, in some embodiments of the present application, the surface of the top support plate 22 facing the first heating element 31 is protruded with a second reflective portion 221, that is, the second reflective portion 221 can be provided on the side of the top support plate 22 facing the first heating element 31. Alternatively, the top support plate 22 is recessed in a direction away from the first heating element 31 to form the second reflective portion 221, that is, the second reflective portion 221 can be provided on the side of the top support plate 22 away from the first heating element 31.

[0050] When the second reflecting portion 221 is disposed on the side of the top support plate 22 facing the first heating element 31, the second reflecting portion 221 can be an integral structure with the top support plate 22, and is formed by stamping or bending a portion of the top support plate 22 in the direction toward the first heating element 31; or, the second reflecting portion 221 can be a separate structure from the top support plate 22, and the second reflecting portion 221 is connected to the surface of the top support plate 22 facing the first heating element 31 by bonding, welding or clamping. When the second reflecting portion 221 is disposed on the side of the top support plate 22 away from the first heating element 31, the second reflecting portion 221 can be an integral structure with the top support plate 22, and is formed by stamping or bending a portion of the top support plate 22 in the direction away from the first heating element 31, so that the heat emitted by the first heating element 31 toward the top support plate 22 can act on the second reflecting portion 221, and the flow angle of the reflected heat is adjusted by the reflection of the second reflecting portion 221.

[0051] Combination Figure 5 , Fig. 9 , Fig.10 , Figures 14 to 16 As shown, in some embodiments of the present application, the second reflecting portion 221 includes a first reflecting segment 2211 and a second reflecting segment 2212 connected to each other, and a portion of the supporting plate is recessed in a direction away from the heating element to form the first reflecting segment 2211 and the second reflecting segment 2212.

[0052] In some embodiments of the present application, the second reflective portion 221 includes a first reflective segment 2211 and a second reflective segment 2212 connected to each other. By setting up a two-part structure, it is convenient to form a structure that is at an angle with the plate surface of the top support plate 22 by stamping or bending. In order to reduce the space occupied by the second reflective portion 221 in the cooking cavity 21 and improve the space utilization rate of the cooking cavity 21, the first reflective segment 2211 and the second reflective segment 2212 are respectively arranged on the side of the top support plate 22 away from the first heating element 31, and are formed by a part of the top support plate 22 being recessed in a direction away from the first heating element 31. Optionally, the left support plate 24 and the right support plate 25 are respectively provided with a protrusion 241 matching the second reflective portion 221, so as to improve the sealing performance after the left support plate 24 and the right support plate 25 are respectively connected to the top support plate 22.

[0053] Combination Figure 5 , Fig. 9 , Fig.10 , Figures 14 to 16 As shown, in some embodiments of the present application, at least one of the first reflection segment 2211 and the second reflection segment 2212 is a planar plate-like structure.

[0054] Optionally, the first reflective segment 2211 and the second reflective segment 2212 can be respectively planar plate structures. The planar plate structure is easy to manufacture, and the top support plate 22 of the entire plate structure can be stamped to form the first reflective segment 2211 and the second reflective segment 2212.

[0055] like Fig.16 As shown, Fig.16 The direction indicated by the straight arrow is the flow direction of part of the heat emitted by the first heating element 31, wherein part of the heat emitted by the first heating element 31 acts on the first reflecting segment 2211 and the second reflecting segment 2212 in a direction perpendicular to the plate surface of the top support plate 22. Since the first reflecting segment 2211 and the second reflecting segment 2212 are respectively arranged at an angle with the plate surface of the top support plate 22, the reflected heat is respectively arranged at an angle with the flow direction of the original heat, thereby reducing the shielding of the heat by the first heating element 31, so that more heat acts on the food in the cooking cavity 21, and improving the cooking efficiency of the cooking device 1. Optionally, the first reflecting segment 2211 and the second reflecting segment 2212 are symmetrical structures. In some embodiments of the present application, at least one of the first reflecting segment 2211 and the second reflecting segment 2212 can also be set as an arc-shaped plate structure, or at least one of the first reflecting segment 2211 and the second reflecting segment 2212 can also be set as a plurality of reflecting segments connected in sequence, and at least one of the plurality of reflecting segments is arranged at an angle with the plate surface of the top support plate 22.

[0056] Combination Figures 14 to 18 As shown, in some embodiments of the present application, the structure of the second heating element 32 may be consistent with the structure of the first heating element 31. For the convenience of description, only the first heating element 31 is used as an example for description. The first heating element 31 includes a tube body 311 and a heating element 312; wherein at least a portion of the tube body 311 is a transparent element, and / or the heating element 312 is a graphene heating element.

[0057] In some embodiments of the present application, the first heating element 31 includes a tube body 311 and a heating element 312 disposed in the tube body 311. The tube body 311 is used to install and fix the heating element 312. The heat emitted by the heating element 312 can pass through the tube body 311 and flow into the cooking cavity 21. Optionally, the tube body 311 can be a transparent member, such as a glass tube, so that the heat emitted by the heating element 312 can pass through the tube body 311, and at the same time, the heat can be reduced from being blocked by the tube body 311 after being reflected by the inner wall of the cooking cavity 21. The heating element 312 can be a graphene heating element, which has good heating efficiency, but at the same time, the graphene heating element is easy to block the reflected heat. Therefore, it is necessary to provide a second reflecting portion 221 on the support plate on the side of the first heating element 31 away from the middle of the cooking cavity 21. The heat reflected by the second reflecting portion 221 does not need to completely avoid the first heating element 31. Since the heat can pass through the glass tube, the angle of the reflected heat only needs to avoid the heating element 312. Optionally, the first heating element 31 further includes a mounting head 313, which is disposed at both ends of the tube body 311 along its own axial direction, and is used to install and fix the tube body 311. Optionally, the left support plate 24 and the right support plate 25, which are disposed oppositely along the axial direction of the tube body 311, are respectively penetrated with a first mounting hole 243, and the mounting heads 313 at both ends of the first heating element 31 can respectively pass through the first mounting holes 243 on both sides, so that the tube body 311 and the heating element 312 are installed inside the cooking cavity 21. Optionally, the first heating element 31 further includes a conductive wire 314 and a connecting tube 315, and part of the conductive wire 314 can pass through the mounting head 313 and be electrically connected to the heating element 312 through the connecting tube 315, so that the external power supply can supply power to the heating element 312 through the conductive wire 314, so that the heating element 312 works and releases heat. In some other embodiments of the present application, the heating element 312 can also be a metal wire heating element.

[0058] Combination Fig. 9 , Fig.10 , 14 to Fig.19 As shown, in some embodiments of the present application, the heating component 30 also includes a grill 33, the grill 33 is formed with a supporting surface 333 for supporting food to be heated and a heat conductive channel 334 passing through the supporting surface, and the first heating element 31 and the second heating element 32 are arranged on the upper and lower sides of the grill 33 in a direction perpendicular to the supporting surface 333.

[0059] In some embodiments of the present application, the grill 33 is formed with a heat conduction channel 334 that penetrates its own support surface 333, so that the heat in the cooking cavity 21 can pass through the heat conduction channel 334 and heat the surface of the food facing the support surface 333 without being blocked by the grill 33.

[0060] Optionally, the grill 33 includes a plurality of first support rods 331, any one of which extends in the front-to-back direction of the housing 10, and the plurality of first support rods 331 are arranged at intervals in the direction from the left support plate 24 to the right support plate 25, so that a support surface 333 is formed by the upper surfaces of the plurality of first support rods 331, and a heat conduction channel 334 is formed between any two adjacent first support rods 331. The support surface 333 can be arranged in the horizontal direction, and the first heating element 31 and the second heating element 32 are respectively arranged at the upper and lower sides of the grill 33 in the vertical direction. The grill 33 also includes two second support rods 332, which are respectively arranged at the front and rear ends of the plurality of first support rods 331, and any one of which extends in the direction from the left support plate 24 to the right support plate 25, and is respectively connected to the plurality of first support rods 331, so as to form the grill 33. Optionally, one end of the plurality of first support rods 331 close to the rear support plate 26 protrudes upward and forms a shielding portion to prevent food from falling from the grill 33 .

[0061] Combination Fig. 9 , Fig.10 , 14 to Fig.18 As shown, in some embodiments of the present application, the heating element 312 includes a main body 3121 and connecting parts 3122 arranged at both ends of the main body 3121. The main body 3121 is arranged in the cooking cavity 21 and forms a first part 3101 with a part of the tube body 311. The connecting parts 3122 located at both ends of the main body 3121 are respectively arranged outside the cooking cavity 21 and form a second part 3102 with another part of the tube body 311.

[0062] Fig.18 The portion within the middle L section is the main body 3121 of the heating element 312, and the main body 3121 has a stronger heat release capacity than the connecting portion 3122. Therefore, in the actual installation process, the first portion 3101 composed of the main body 3121 can be placed in the cooking cavity 21 to quickly increase the temperature in the cooking cavity 21, and the second portion 3102 composed of the connecting portion 3122 is arranged outside the cooking cavity 21, so as to be used for installing and fixing the first heating element 31, and to facilitate the connection between the connecting portion 3122 and the conductive wire 314. At the same time, since the heat release capacities of the main body 3121 and the connecting portion 3122 are inconsistent, placing the main body 3121 in the cooking cavity 21 and placing the connecting portion 3122 outside the cooking cavity 21 can improve the temperature consistency at various positions in the cooking cavity 21 and reduce the temperature inconsistency at various positions in the cooking cavity 21 caused by different heat release capacities.

[0063] Combination Fig. 9 , Fig.10 , 14 to Fig. 20As shown, in some embodiments of the present application, the cooking chamber assembly 20 further includes a shielding member 293, at least one support plate is penetrated by a first mounting hole 243, the second portion 3102 passes through the first mounting hole 243 and extends to the outside of the cooking chamber 21, and an installation gap (not shown in the figure) is formed between the heating element and the inner wall surface of the first mounting hole 243, and the shielding member 293 is disposed at the first mounting hole 243 and is configured to cover at least part of the installation gap.

[0064] In some other embodiments of the present application, most of the tube body 311 and the heating element are arranged in the cooking cavity 21 to form a first part 3101, and are used to heat food. Another part of the tube body 311 and the heating element are arranged outside the cooking cavity 21 to form a second part 3102, so as to facilitate the installation and fixing of the first heating element 31. Among them, the mounting head 313 is arranged outside the cooking cavity 21 and is used to install and fix the first heating element 31. Among them, the radial dimension of the tube body 311 is smaller than the maximum cross-sectional dimension of the mounting head 313, so that it is convenient to fix and install the first heating element 31 through the mounting head 313. The maximum cross-sectional dimension of the mounting head 313 is smaller than the radial dimension of the first mounting hole 243, so that it is convenient for the mounting head 313 to pass through the first mounting hole 243. Since the radial dimension of the tube body 311 is smaller than the maximum cross-sectional dimension of the mounting head 313, after the tube body 311 is passed through the first mounting hole 243, an installation gap is formed between the tube body 311 and the inner wall surface of the first mounting hole 243.

[0065] During the heating process of the cooking device 1, the heat in the cooking cavity 21 can be lost to the outside of the cooking cavity 21 through the installation gap, thereby causing the heat loss in the cooking cavity 21, reducing the heating efficiency of the first heating element 31, and causing the temperature rise outside the cooking cavity 21. Therefore, in the embodiment of the present application, by providing a shielding member 293, the shielding member 293 is used to shield at least part of the installation gap, so that the heat inside the cooking cavity 21 can be reduced from flowing out to the outside of the cooking cavity 21 through the installation gap, thereby reducing the heat loss in the cooking cavity 21, improving the heating efficiency of the first heating element 31, and reducing the temperature rise outside the cooking cavity 21.

[0066] Combination Fig. 9 , Fig.10 , 14 to Fig. 20 As shown, the shielding member 293 includes a separable first shielding member 2931 and a second shielding member 2932, which are respectively connected to the cooking cavity assembly 20 in a detachable manner, and the first shielding member 2931 and the second shielding member 2932 are respectively configured to cover part of the installation gap.

[0067] For the convenience of description, in the embodiments of the present application, only the example in which the shielding member 293 is disposed on the left support plate 24 is used for explanation.

[0068] In some embodiments of the present application, the shielding member 293 includes two separate parts, namely a first shielding member 2931 and a second shielding member 2932, so that after the first heating member 31 passes through the first mounting hole 243, the first shielding member 2931 and the second shielding member 2932 are respectively arranged at the first mounting hole 243 of the left support plate 24, and are used to jointly block the installation gap and reduce the shielding member 293 from blocking the first heating member 31 during the process of the first heating member 31 passing through the first mounting hole 243. Among them, the first covering member 2931 and the second covering member 2932 are respectively connected to the left support plate 24 in a detachable manner, such as being connected to the left support plate 24 by snapping, plugging or screwing, so that after the first heating member 31 passes through the first mounting hole 243, the first covering member 2931 and the second covering member 2932 are respectively connected to the left support plate 24, thereby reducing the first covering member 2931 and the second covering member 2932 blocking the first heating member 31 in the process of the first heating member 31 passing through the first mounting hole 243, thereby improving the smoothness of the first heating member 31 passing through the first mounting hole 243.

[0069] Combination Fig. 9 , Fig.10 , 14 to Fig. 20 As shown, in some embodiments of the present application, the first shielding member 2931 and the second shielding member 2932 are respectively arranged on opposite sides of the first heating member 31 along the radial direction of the first heating member 31, and a first notch 2935 is formed on the side of the first shielding member 2931 facing the second shielding member 2932, and a second notch is formed on the side of the second shielding member 2932 facing the first shielding member 2931, the first notch 2935 and the second notch are respectively semicircular notches, and the radius size of the first notch 2935 and the radius size of the second notch are respectively equal to the radius size of a portion of the first heating member 31 arranged in the cooking cavity 21.

[0070] In some embodiments of the present application, the radius of the portion of the first heating element 31 disposed in the cooking cavity 21 is the radius of the tube body 311. After the first heating element 31 passes through the first mounting hole 243, the first shielding member 2931 can be disposed on one side of the first heating element 31 in the radial direction, and the first notch 2935 can be sleeved on the outside of the tube body 311, so that the first shielding member 2931 can shield the installation gap on one side of the radial direction of the first heating element 31. At the same time, the second shielding member 2932 can be disposed on the other side of the first heating element 31 in the radial direction, and the second notch can be sleeved on the outside of the tube body 311, so that the second shielding member 2932 can shield the installation gap on the other side of the radial direction of the first heating element 31.

[0071] By setting the first notch 2935 and the second notch as semicircular notches with the same radius as the tube body 311 respectively, it can be ensured that the opening area formed between the first notch 2935 and the second notch is larger than the cross-sectional area of ​​the tube body 311 along the radial direction, thereby facilitating the first shielding member 2931 and the second shielding member 2932 to be respectively mounted on the outside of the tube body 311 to block the installation gap.

[0072] Optionally, the first shielding member 2931 and the second shielding member 2932 are symmetrical structures. For the convenience of description, the embodiment of the present application is only described by taking the first shielding member 2931 as an example. The first shielding member 2931 is a sheet-like structure, which is easy to process and easy to fit with the board surface of the left support plate 24, thereby improving the sealing between the first shielding member 2931 and the left support plate 24, and reducing the heat in the cooking cavity 21 from being lost to the outside of the cooking cavity 21 through the gap between the first shielding member 2931 and the left support plate 24. Among them, the first shielding member 2931 includes a main board portion 2933 and a first plug-in portion 2934. The main board portion 2933 is a roughly rectangular structure, and the first plug-in portions 2934 are respectively provided at both ends in the length direction, and the first plug-in portion 2934 is arranged at an angle with the main board portion 2933. Specifically, the first plug-in portion 2934 is perpendicular to the main board portion 2933. The left support plate 24 is provided with a fifth plugging slot 244. When the first shielding member 2931 is connected to the left support plate 24, the main board portion 2933 fits the outer side surface of the left support plate 24, and the first plugging portion 2934 is plugged into the fifth plugging slot 244 on both sides of the first mounting hole 243, thereby fixing the first shielding member 2931 to the left support plate 24.

[0073] Combination Fig. 9 , Fig.10 , 14 to Fig. 20 As shown, in some embodiments of the present application, one end of the first shielding member 2931 having the first notch 2935 abuts against one end of the second shielding member 2932 having the second notch.

[0074] By abutting one end of the first shielding member 2931 provided with the first notch 2935 with one end of the second shielding member 2932 provided with the second notch, that is, abutting the edge of the first notch 2935 with the edge of the second notch, the first notch 2935 and the second notch are combined to form a circular opening, and the radius of the circular opening is consistent with the radius of the tube body 311, so that the first shielding member 2931 and the second shielding member 2932 are completely fitted to the outer surface of the tube body 311, reducing the gap between the shielding member 293 and the outer surface of the tube body 311, thereby reducing the heat in the cooking cavity 21 from flowing out to the outside of the cooking cavity 21 through the gap between the shielding member 293 and the outer surface of the tube body 311.

[0075] Combination Fig. 9 , Fig.10 , 14 to Fig. 20 As shown, in some embodiments of the present application, along a direction perpendicular to the side wall where the first mounting hole 243 is located, an outer contour formed by the projection of the shielding member 293 on the side wall is arranged outside the first mounting hole 243 .

[0076] In some embodiments of the present application, the shielding member 293 includes a first shielding member 2931 and a second shielding member 2932 as in the above-mentioned embodiments, and the main board portions 2933 of the first shielding member 2931 and the second shielding member 2932 are respectively roughly rectangular structures, so that the projections of the first shielding member 2931 and the second shielding member 2932 on the left support plate 24 form a roughly rectangular structure, wherein the roughly rectangular structure is surrounded by the outside of the first mounting hole 243, thereby blocking the installation gap, thereby reducing the heat in the cooking cavity 21 from flowing out of the cooking cavity 21 through the installation gap.

[0077] Optionally, in some embodiments of the present application, along a direction perpendicular to the left support plate 24, an outer contour formed by the projection of the shielding member 293 on the left support plate 24 is arranged around the outside of the first mounting hole 243. At the same time, one end of the first shielding member 2931 having a first notch 2935 is abutted against one end of the second shielding member 2932 having a second notch, and the first notch 2935 and the second notch are respectively set to semicircular notches equal to the radius size of the tube body 311, thereby completely blocking the installation gap between the first mounting hole 243 and the tube body 311, thereby improving the sealing of the cooking cavity 21 and reducing the heat in the cooking cavity 21 from flowing out to the outside of the cooking cavity 21 through the installation gap.

[0078] Combination Figure 4 , Fig. 9 , Fig.10 and Fig.18 As shown, in some embodiments of the present application, the cooking chamber assembly 20 further includes a baffle, which is disposed at the outer edge of the first opening 211, and along a direction perpendicular to the baffle, the projection of the second portion 3102 on the plane where the baffle is located is within the range of the baffle.

[0079] In some embodiments of the present application, the baffle includes a first baffle 291 and a second baffle 292, and the first baffle 291 and the second baffle 292 are respectively arranged on the left and right sides of the first opening 211. Since the second portion 3102 extends out of the cooking cavity 21, the second portion 3102 can be shielded by the first baffle 291 and the second baffle 292, thereby improving the overall appearance of the cooking cavity assembly 20. At the same time, the cooking cavity assembly 20 can also be connected to the housing 10 through the first baffle 291 and the second baffle 292. Optionally, the first baffle 291 and the second baffle 292 can be connected to the front side plate 13 respectively. At the same time, due to the provision of the first baffle 291 and the second baffle 292, the size of the cooking cavity assembly 20 can be reduced along the left and right direction of the cooking cavity assembly 20, thereby forming a cooking cavity 21 with a smaller volume, so that the heat in the cooking cavity 21 is more concentrated, and the cooking effect on the food is improved.

[0080] Combination Figure 4 , Figure 5 , Fig.15 , Figure 21 to Figure 23 As shown, in some embodiments of the present application, the cooking device 1 also includes a door body assembly 40, which is disposed at the first opening 211 and is used to open or close the cooking cavity 21. The door body assembly 40 includes a glass plate 41, wherein a portion of the support plate protrudes from the surface of the interior of the cooking cavity 21 and is provided with a third reflecting portion 222, and the third reflecting portion 222 is disposed between at least part of the heating element and the glass plate 41. When the door body assembly 40 closes the cooking cavity 21, the orthographic projection of the heating element in the plane where the glass plate 41 is located at least partially overlaps with the orthographic projection of the third reflecting portion 222 in the plane where the glass plate 41 is located.

[0081] In some embodiments of the present application, the door assembly 40 is disposed at the first opening 211 and is used to open or close the cooking cavity 21. Optionally, the door assembly 40 can be disposed at the first opening 211 in a rotating manner, or the door assembly 40 can be disposed at the first opening 211 in a pulling manner. In order to facilitate the heating of food in the cooking cavity 21 through the door assembly 40, the door assembly 40 includes a glass plate 41, and the glass plate 41 can be disposed opposite to at least a portion of the first opening 211.

[0082] Since the heat reflectivity of the glass plate 41 is low, the heat in the cooking cavity 21 will be dissipated to the outside of the cooking cavity 21 through the glass plate 41 after contacting the glass plate 41 during the radiation process, thereby causing the heat in the cooking cavity 21 to be lost and reducing the cooking efficiency of the cooking device 1. Therefore, in order to reduce the heat loss in the cooking cavity 21 and improve the cooking efficiency of the cooking device 1, it is necessary to reduce the contact between the heat in the cooking cavity 21 and the glass plate 41. Optionally, a third reflecting portion 222 is protruding from the surface of a portion of the support plate toward the interior of the cooking cavity 21, and the third reflecting portion 222 is disposed between the heating element and the glass plate 41, and the orthographic projection of the heating element in the plane where the glass plate 41 is located at least partially overlaps with the orthographic projection of the third reflecting portion 222 in the plane where the glass plate 41 is located, so that the heat emitted by the heating component 30 toward the glass plate 41 is blocked and reflected by the third reflecting portion 222, thereby reducing the contact between the heat and the glass plate 41 and the heat loss in the cooking cavity 21. At the same time, the heat emitted by the heating component 30 can change its angle after contacting the third reflecting portion 222 and flow toward the interior of the cooking cavity 21 again, thereby improving the temperature consistency at different positions in the cooking cavity 21, and further allowing the food in the cooking cavity 21 to be heated evenly, thereby improving the cooking efficiency and cooking effect of the cooking device 1.

[0083] In some embodiments of the present application, the third reflective portion 222 is an integrated structure with the support plate, and is formed by bending a portion of the support plate toward the inside of the cooking cavity 21, thereby forming a protruding structure toward the inside of the cooking cavity 21, and is used to shield and reflect heat. Optionally, along a vertical plane perpendicular to the glass plate 41, the cross-sectional shape of the third reflective portion 222 can be triangular, square or arc-shaped.

When the door assembly 40 closes the cooking cavity 21, the orthographic projection of the first heating element 31 in the plane where the glass plate 41 is located is within the range of the orthographic projection of the third reflecting portion 222 in the plane where the glass plate 41 is located.

[0085] In some embodiments of the present application, when the door assembly 40 closes the cooking cavity 21, the orthographic projection of the first heating element 31 in the plane where the glass plate 41 is located is within the range of the orthographic projection of the third reflective portion 222 in the plane where the glass plate 41 is located. That is, in the reverse direction perpendicular to the glass plate 41, the third reflective portion 222 completely blocks the first heating element 31, and the heat emitted by the first heating element 31 in the direction perpendicular to the glass plate 41 completely acts on the third reflective portion 222, and the heat is reflected again by the third reflective portion 222 to flow into the cooking cavity 21, thereby reducing the heat loss of the first heating element 31 through the glass plate 41. Optionally, the left support plate 24 and the right support plate 25 are respectively provided with a recessed portion 242 matching the third reflective portion 222, so as to improve the sealing performance after the left support plate 24 and the right support plate 25 are respectively connected to the top support plate 22.
