Detailed Description
The utility model is further described below with reference to the drawings and examples.
Referring to fig. 1-5, a heat dissipation structure of an electric pizza oven comprises a baking cavity 1, a casing 2, a heat dissipation air duct 3, a fan 4 and an electric control device 5. The baking cavity 1 is arranged in the shell 2, the front parts of the baking cavity 1 and the shell 2 are fixedly connected through the fixing plate 6, and the fixing plate 6 is provided with a hollowed-out part 61 corresponding to the inlet and outlet 11 of the baking cavity 1. The heat dissipation air duct 3, the fan 4 and the electric control device 5 are arranged between the baking cavity 1 and the shell 2.
The fixed plate 6 is provided with a hot air outlet 62 above the inlet 11. The heat dissipation wind channel 3 sets up at roast cavity 1 top surface, and the air outlet intercommunication hot-blast export 62 of heat dissipation wind channel 3, and the air intake setting of heat dissipation wind channel 3 is at roast cavity 1 rear portion top surface. Wherein, the heat dissipation wind channel 3 one side is opened, and the roast cavity 1 surface is laminated to wind channel device open side.
The fan 4 is arranged outside the air inlet of the heat dissipation air duct 3, the fan 4 forms a negative pressure area 7 at the rear part of the baking cavity 1, and the heat dissipation air duct 3 and the negative pressure area 7 are distributed in an L shape. Wherein, fan 4 sets up at roast cavity 1 rear end top. Specifically, the fan 4 may be fixed on top of the rear end surface of the baking chamber 1 by a bracket. The fan 4 can also be fixedly connected with the shell 2 through a bracket, so that the fan 4 is suspended at the top of the rear end face of the baking cavity 1. The air outlet of the fan 4 horizontally faces the air inlet of the heat dissipation air duct 3, and the air inlet of the fan 4 vertically faces the bottom surface of the shell 2.
The electric control device 5 is a circuit board, and the electric control device 5 is arranged on the rear end face of the baking cavity 1, namely, the electric control device 5 is arranged in the negative pressure area 7.
