The line board box 300 comprises a box body 310 and a box cover 320, wherein the box body 310 is connected with the main body 100, the box cover 320 is detachably connected with the box body 310 to facilitate replacement of damaged electronic components on the main control board 330, maintenance cost is reduced, and a heat dissipation hole 321 communicated with the mounting cavity 311 is formed in the box cover 320 to form a window 312. In the use process of the electric cooker 10, electronic components such as resistors and metal interfaces on the main control panel 330 can continuously generate heat, and as the box cover 320 is provided with the heat dissipation holes 321, the heat generated by the main control panel 330 can be dissipated through the heat dissipation holes 321 and then dissipated to the outside from the air holes 210 on the shell 200, namely, the electric cooker 10 forms a heat dissipation channel from the main control panel 330 to the heat dissipation holes 321 to the air holes 210 and communicated with the outside, and the heat dissipation channel is used for dissipating heat of the main control panel 330.

In an embodiment, the main control board 330 is provided with a heat dissipation structure 331 for conducting heat dissipation, the position of the heat dissipation structure 331 corresponds to the position of the heat dissipation hole 321, that is, the heat dissipation structure 331 is disposed at the position of the main control board 330 opposite to the heat dissipation hole 321, and the heat dissipation structure 331 may be a heat sink, a heat pipe, a copper foil, or the like. It is understood that in other embodiments, the location of the heat dissipation structure 331 may not be set to correspond to the location of the heat dissipation holes 321 without regard to optimizing the heat dissipation effect.
