Background

An oven is a device that accommodates food in a closed space and heats and cooks the food. In the process of baking food by using an oven, more and more users prefer to bake meat slices, meat strings, vegetable slices and the like by using the oven, but the existing heating mode is mostly heating by heat conduction of a heating pipe.

At present, the industry generally uses a heater to directly heat food for food processing, but the existing heating system on the market has the following problems:

(1) the oven is heated by air heat conduction, and the heating speed is low;

(2) the heating pipe positioned on the wall of the inner container is arranged in the oven, and a heating plate capable of heating food is not arranged in the cavity;

(3) considering the aesthetic degree of the oven, the lower heater is generally placed outside the cavity by adopting a hidden design, so that partial heat can be shielded in the food baking process, meanwhile, due to the shielding of the heating plate, the heat transfer efficiency of the lower heater is much lower than that of the upper heater, when the heating plate is used for cooking food, the upper surface of the upper part of the food heated by the heater is easy to color, the lower surface of the food cannot be colored, and the food needs to be turned over in the use process; however, the user can turn over the dough by himself, so that the user cannot master proper turning time, and uneven coloring and inconsistent degree of ripeness of the front and the back are easily caused;

(4) part of the oven uses the heating plate with the heating part inside the oven, so that the heating part and the electrical connection are required to be arranged on the part frequently taken by a user, the use by the user is inconvenient, and the risk of electrical leakage exists;

(5) the heating plate with the heating component is arranged in the heating plate, so that the heating plate is not easy to take and place, and the combination position of the heating plate and the heater is exposed or a protective cover is added due to the arrangement of the built-in heater, so that the heating plate with heavy oil stains after being baked is not easy to clean;

(6) the heating plate with the built-in heater generally needs to make great structural modification on an existing oven, cannot be directly carried on a common oven platform for use, is high in development and user use cost, generally increases the heating plate with the built-in heater, and cannot completely retain the functions of a traditional oven after great structural modification is carried out on the existing oven, so that function loss is caused.
