Abstract

The present disclosure relates to a method of controlling the temperature of an air fryer. The temperature control method of the air fryer comprises the steps of obtaining a first temperature control temperature after the air fryer is started, obtaining a real-time temperature through a temperature sensor, and controlling a heating assembly to directly enter a constant-temperature sub-stage through a controller based on the fact that the real-time temperature is greater than or equal to the first temperature control temperature. Therefore, after the air fryer is started, if the real-time temperature in the air fryer is greater than or equal to the first temperature control temperature, the air fryer is in a hot start state, namely the machine body and the pot body are hot enough, the heating is not needed through the preheating sub-stage and the temperature control sub-stage, and the air fryer can directly jump to the constant temperature sub-stage for maintaining the temperature control temperature for control, so that the serious flushing temperature caused by the fact that the preheating power is continuously applied to the pot body which is hot is prevented, and the temperature control precision is improved.

Description

Temperature control method of air fryer Technical Field The disclosure relates to the technical field of intelligent household appliances, in particular to a temperature control method of an air fryer. Background An air fryer is a popular cooking appliance and operates on the principle that hot air is generated by a heating assembly to heat the food in a cooking cavity. Accurate temperature control is critical in order to achieve optimal cooking results and energy efficiency. Existing air fryer temperature control schemes typically employ a fixed heating profile after start-up, e.g., performing fixed pre-heat, temperature control, thermostat phases. However, because of the difference of the heat absorption capacity of the fryer materials, the temperature collected by the air fryer through the temperature sensor (such as a negative temperature coefficient thermistor (Negative Temperature Coefficient, NTC)) in different states is different from the actual temperature in the fryer, so that the phenomenon of flushing or excessively low preheating temperature occurs. For example, patent document CN119564054a discloses a temperature control method of an air fryer, in which a dynamic temperature control point is set by a temperature sensor relative to a mounting position of a heating assembly, so as to avoid too high a temperature or too low a preheating temperature during heating. However, the above patent document does not consider that after the air fryer has been heated to a higher temperature, such as entering a temperature control, constant temperature stage, the user may restart the cooking for a short time after taking out the food (pulling the pot) during cooking or canceling the program or for a short time after finishing the cooking. At this time, the heating tube has a high Yu Wenshang temperature rise trend of the cooking cavity and the pot body, the NTC temperature rise trend beside the heating tube is not changed, if the complete cold start preheating process is still mechanically executed, the preheating is excessive, the heating is still over-high, the energy is wasted, the food taste is possibly influenced due to the over-high initial temperature, and even potential safety hazards are generated. On the contrary, when the air fryer just enters the preheating stage, the user restarts in a short time after taking out food (taking out the pot) or canceling the program in the middle of cooking, at this time, the equipment does not reach the preheating temperature, but the equipment is erroneously judged to be hot-started and skips the necessary preheating stage, so that insufficient heating is caused, the cooking time is prolonged, and the user experience is affected. Disclosure of Invention In order to solve the technical problems that the heating is excessive and the flushing temperature is too high due to the fact that equipment heat accumulation is in a hot start state under complex scenes such as taking out food (taking out a pot) during cooking or restarting in a short time after a program is canceled by a user, and the cooking effect is affected, the disclosure provides a temperature control method of an air fryer. In addition, the method can further solve the technical problem of low heating efficiency caused by insufficient preheating due to state misjudgment under the complex scene of the user. In a first aspect, the present disclosure provides a method of controlling the temperature of an air fryer, the method comprising: After the air fryer is started, acquiring a first temperature control temperature, and acquiring a real-time temperature through a temperature sensor, wherein the first temperature control temperature is a preheating sub-stage temperature control temperature set based on a cold start state; based on the real-time temperature being greater than or equal to the first temperature control temperature, the heating assembly is controlled by the controller to directly enter the constant temperature sub-stage. In some embodiments, the method further comprises: Based on that the real-time temperature is smaller than the first temperature control temperature, and the difference value between the real-time temperature and the first temperature control temperature is larger than or equal to a first preset difference value, the heating assembly is controlled by the controller to sequentially enter a preheating sub-stage, a temperature control sub-stage and a constant temperature sub-stage; Based on the fact that the real-time temperature is smaller than the first temperature control temperature, the difference between the real-time temperature and the first temperature control temperature is smaller than a first preset difference, the heating assembly is controlled by the controller to directly enter a constant temperature sub-stage or sequentially enter a preheating sub-stage, a temperature control sub-stage and a constant temperature sub-stage according to the value of the historical
