Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to a back air intake structure of a pizza oven. Background Art

[0002] Pizza, also known as pizza, pizza cake, pizza, pizza, and pizza, is made of special sauces and fillings. It originated in Naples, Italy and has become a global food, but people in different countries and regions have slightly different tastes when eating this kind of pizza.

[0003] In the process of making pizza, a pizza oven is needed. The pizza oven is an electrical appliance specially used for making pizza and can bake pizza. The existing pizza oven structure generally includes: a box body, a box door, a heating mechanism, an air inlet mechanism and a baking tray. When making pizza, the pizza is placed in the baking tray, and then the pizza is baked through the heating mechanism and the air inlet mechanism.

[0004] However, the existing pizza ovens still have certain defects during use. During the operation of the oven, the heat of the oven itself plus the heat generated by the power board itself will cause the power board to become hot. The long-term high temperature of the power board will lead to an increased failure rate. Based on the above problems, we provide a pizza oven back air intake structure to solve the above-mentioned problems. Utility Model Content

[0020] The utility model can cool the power board during operation by means of the air inlet, power board, bottom air outlet and air supply assembly. During operation, when the wind collecting blades and the wind dissipating blades rotate to supply air to the inside of the inner shell plate, negative pressure is generated in the first installation cavity. Then the external air enters the power board through the air inlet, and then enters the first installation cavity through the bottom air outlet. Since the external cold air is introduced from the outside, the air passes through the power board and takes away the heat on the power board, thereby achieving heat dissipation of the power board. The air supply assembly can achieve heat dissipation of the power board while normally supplying air to the pizza oven main body and cooperating with the heating mechanism inside the pizza oven main body to bake pizza, thereby solving the problem of high temperature of the power board without adding heat dissipation components. The utility model has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

When the air gathering blade 10 and the air dispersing blade 14 rotate to send air to the inside of the pizza oven body 16, a negative pressure will be generated in the first installation cavity 9, and then the external air will enter the power board 4 through the air inlet 3, and then enter the first installation cavity 9 through the bottom air outlet 8. Since the external cold air is introduced from the outside, the heat on the power board 4 will be taken away when the air passes through the power board 4, thereby achieving the heat dissipation of the power board 4. The above method can solve the problem of high temperature of the power board 4 without adding heat dissipation components. At the same time, the blade protection cover 15 provided can protect the air dispersing blade 14 when in use to avoid accidentally touching the air dispersing blade 14 during use.
