[0058] By setting the cross-sectional size of the first insertion hole 324 to be smaller than the maximum cross-sectional size of the second portion 3102, when the second portion 3102 is inserted into the first insertion hole 324 in the direction from the inside of the cooking cavity 21 to the outside of the cooking cavity 21, the second portion 3102 can abut against the edge of the first insertion hole 324, thereby limiting the depth of the insertion of the second portion 3102 into the first insertion hole 324, and limiting the insertion size of the second portion 3102 in the axial direction of the pipe body 311.

[0059] In combination Figures 3 to 9 As shown in some embodiments of the present application, the heating element 31 further comprises a mounting head 313, at least one end of the pipe body 311 is provided with the mounting head 313 in the axial direction of the pipe body 311, and the mounting head 313 is connected to the mounting cover 32.

[0060] In some embodiments of the present application, the mounting head 313 is arranged at at least one end in the axial direction of the pipe body 311, so that the heating element 31 is mounted and positioned by the mounting head 313. In this case, the mounting head 313 can be inserted into and fixed in the first insertion hole 324, and the mounting head 313 and the first insertion hole 324 can be clamped to each other. Alternatively, in a plane perpendicular to the arrangement direction of the first portion 3101 and the second portion 3102, the cross-sectional size of the first insertion hole 324 is smaller than the maximum cross-sectional size of the mounting head 313, and part of the mounting head 313 can pass through the first insertion hole 324, and another part of the mounting head 313 is arranged in the mounting cavity and abuts against the edge of the first insertion hole 324.

[0061] Alternatively, the heating element 31 further comprises an electrically conductive wire 314 and a connecting pipe 315, the electrically conductive wire 314 is arranged outside the cooking cavity 21, part of the electrically conductive wire 314 can pass through the mounting head 313 and is electrically connected to the heating element 312 through the connecting pipe 315, so that an external power supply can supply power to the heating element 312 through the electrically conductive wire 314 to make the heating element 312 work and release heat.

[0062] In combination Figures 3 to 9 As shown in some embodiments of the present application, the heating element 312 comprises a main body portion 3121 and connecting portions 3122 arranged at both ends of the main body portion 3121, the thermal efficiency of the main body portion 3121 is greater than that of the connecting portions 3122, the main body portion 3121 is arranged in the cooking cavity 21 and forms the first portion 3101 with part of the pipe body 311, and the connecting portions 3122 are arranged outside the cooking cavity 21 and form the second portion 3102 with another part of the pipe body 311.

[0063] As shown in some embodiments of the present application, the heating element 312 comprises a main body portion 3121 and connecting portions 3122 arranged at both ends of the main body portion 3121, the thermal efficiency of the main body portion 3121 is greater than that of the connecting portions 3122, the main body portion 3121 is arranged in the cooking cavity 21 and forms the first portion 3101 with part of the pipe body 311, and the connecting portions 3122 are arranged outside the cooking cavity 21 and form the second portion 3102 with another part of the pipe body 311. Figure 7 Figure 7 ​The main part 3121 of the heating element 312 in the middle L section range has a stronger heat dissipation capacity than the connecting part 3122. Therefore, during actual installation, the first part 3101 composed of the main part 3121 can be placed in the cooking cavity 21 to quickly raise the temperature in the cooking cavity 21, and the second part 3102 composed of the connecting part 3122 is placed outside the cooking cavity 21 to facilitate the installation and fixation of the heating element 31 and the connection of the connecting part 3122 and the conductive wire 314. At the same time, since the heat dissipation capacities of the main part 3121 and the connecting part 3122 are different, the main part 3121 is placed in the cooking cavity 21 and the connecting part 3122 is placed outside the cooking cavity 21, which can improve the temperature consistency at each position in the cooking cavity 21 and reduce the temperature inconsistency at each position in the cooking cavity 21 due to the different heat dissipation capacities.

The second part 3102 at both ends can respectively pass through the first mounting hole 241 of the left support plate 24 and the right support plate 25 and be inserted into the mounting cavity of the mounting cover 32 on both sides, so as to reduce the heat diffusion caused by the operation of the second part 3102 through the mounting cover 32. In order to facilitate the installation of the heating element 31 in the cooking cavity 21, the maximum cross-sectional dimension of the heating element 31 in a plane perpendicular to the arrangement direction of the first part 3101 to the second part 3102 is less than or equal to the size of the first mounting hole 241. Therefore, the heating element 31 can pass through the first mounting hole 241 of the left support plate 24 and the right support plate 25 in sequence, and the first part 3101 is placed in the cooking cavity 21. Alternatively, the heating element 31 can pass through the first mounting hole 241 of the right support plate 25 and the left support plate 24 in sequence, and the first part 3101 is placed in the cooking cavity 21.

[0065] With the first mounting hole 241 of the left support plate 24 and the right support plate 25 being sequentially penetrated by the heating element 31 in the installation as an example, in the specific installation process of the heating element 31, one mounting cover 32 can be connected with the right support plate 25, and the first mounting hole 241 of the right support plate 25 is arranged opposite to the mounting cavity. The heating element 31 is placed on the side of the left support plate 24 away from the cooking cavity 21, then the heating element 31 is sequentially penetrated along the axial direction through the first mounting hole 241 of the left support plate 24 and the right support plate 25, and the end of the heating element 31 away from the left support plate 24 is inserted into the first insertion hole 324 of the right mounting cover 32.
