Description

Cooking apparatus Technical Field The application relates to the technical field of kitchen ware, in particular to cooking equipment. Background In cooking equipment with a baking function (such as an oven, a steaming oven, a kitchen steaming and baking integrated machine and a micro steaming and baking integrated machine), a heating pipe and a hot air blower are two main core components. The heating pipe is a heat source of the cooking device and is responsible for converting electric energy into heat energy, and the cooking device toasts food by the heat generated by the heating pipe. The hot air blower blows hot air near the heating pipe to food rapidly, so that the non-uniformity of natural convection is broken, and local overheating or uneven cooking can be avoided. Because the hot air blower helps to promote the fluidity of the hot air, the heat can be more rapidly transferred to the surface of the food, so that the baking time can be shortened, and the baking efficiency can be improved. In conventional cooking devices with a baking function, a large heating pipe is usually disposed at the top of the inner container, and a large hot air blower is disposed at the top or back of the inner container. The structure has obvious temperature control defect that the temperature of each part in the inner container can be obviously changed when the temperature of the inner container is regulated by the cooking equipment. When the temperature abnormality (the too high or too low temperature) occurs in the local area in the inner container, accurate local temperature adjustment cannot be performed on the temperature abnormality area, and in the process of adjusting the temperature of the temperature abnormality area, the area with normal temperature in the inner container is forced to perform unnecessary temperature adjustment, so that the baking effect of the cooking equipment is not facilitated to be improved. Disclosure of utility model Based on this, it is necessary to provide a cooking apparatus in view of the above-described problems. In order to solve the problems, the application provides the following technical scheme: a cooking apparatus, the cooking apparatus comprising: an inner container; The baking tray is positioned in the inner container; The hot air blower is arranged on the top wall of the inner container and is positioned above the baking tray, and is provided with a rotating shaft and fan blades, wherein the fan blades are fixedly arranged on the rotating shaft; A heating pipe arranged above the inner container and above the baking tray, and The thermistor is arranged on the baking tray; The heating device comprises a liner, a plurality of air heaters, heating pipes and thermistors, wherein the air heaters, the heating pipes and the thermistors are all arranged in a one-to-one correspondence manner, all the air heaters are located at the same height position in the liner and are uniformly distributed, the air heaters, the heating pipes and the thermistors which correspond to each other are sequentially arranged along the axial direction of a rotating shaft, each thermistor is electrically connected with the corresponding heating pipe in a series connection manner, and the heating pipes are located in different closed loops. The cooking device has at least the following beneficial effects: When the temperature of the local area in the liner is too high, the resistance value of the thermistor in the local area can be obviously increased, the current in a closed loop where the thermistor is positioned is reduced, in other words, the current of a heating pipe corresponding to the thermistor is reduced, the heating power of the heating pipe is reduced, the temperature in the local area can be reduced, and the temperature of the local area is favorable for recovering to be normal. In addition, the resistance value of the thermistor in the region with normal temperature in the inner container is not changed obviously, and the temperature in the region with normal temperature in the inner container is not changed obviously. When the temperature of a local area in the liner is too low, the resistance value of the thermistor in the local area can be obviously reduced, and the current in a closed loop where the thermistor is positioned is increased, in other words, the current of a heating pipe corresponding to the thermistor is increased, the heating power of the heating pipe is increased, and the temperature in the local area can be increased, so that the temperature of the local area is favorable for recovering to be normal. In addition, the resistance value of the thermistor in the region with normal temperature in the inner container is not changed obviously, and the temperature in the region with normal temperature in the inner container is not changed obviously. In summary, in the cooking device, when the temperature abnormality occurs in the local area in the inner container, the resistance of th
