[0034] More specifically, as shown in the accompanying drawings Fig. 3 and the accompanying drawings Fig. 4 As shown, the mounting bracket 11 comprises a protruding rail 111 extending in the vertical direction, a plurality of protruding rails 111 are arranged in parallel, the connecting portion 41 comprises a recess 411, the recess 411 on the fixing plate 4 is matched with the corresponding protruding rail 111 inside the shell 1, and the recess 411 and the protruding rail 111 are slidably matched. The mounting bracket 11 and the fixing plate 4 adopt the matching mode of the protruding rail 111 and the recess 411, during assembly, only need to slide the fixing plate 4 provided with the electric heating module 2 into the shell 1, and make the recess 411 on the fixing plate 4 and the protruding rail 111 inside the shell 1 slidably matched, so that the positioning and installation of the electric heating module 2 can be realized, and the disassembly and assembly operation is more convenient.

[0035] Among them, the protruding rails 111 are distributed on the inner side and four inner corners of the shell 1, the corner protruding rail 111a and the inner side wall protruding rail 111b are recorded, the recess 411 on the fixing plate 4 is matched with the corresponding protruding rail 111 and avoids combination, and one or more mounting modes are formed.

[0036] For example, the number of protruding rails 111b arranged on the front and rear sides of the shell 1 is two, and the number of recesses 411 arranged on the front and rear sides of the fixing plate 4 is two.

[0037] Taking the following three mounting modes as examples:

[0038] (1) The recesses 411 on the front and rear sides of the fixing plate 4 are respectively combined and mounted with the protruding rails 111b arranged on the front and rear sides of the shell 1, and the fixing plate 4 avoids the four protruding rails 111a arranged on the inner corners;
