An anti-overflow control method for controlling a food processor that is a soybean milk mixing machine, a cell wall breaking machine or a blender comprising: when the food processor is powered on, judging whether the food processor generates an enabled instruction for detecting a boiling point based on external actions during a preset time period; if the food processor generates the enabled instruction for detecting the boiling point based on external actions during the preset time period, a pre-stored process for detecting the boiling point is started by a process starting module 20, to obtain a current boiling point of water at the current location of the food processor; controlling the food processor to heat water inside the food processor based on the current boiling point of the water; if the food processer fails to generate the enabled instruction for detecting the boiling point based on external actions during the preset time period, controlling the food processer to heat water inside the food processor based on a pre-stored boiling point in the food processor, which is the current boiling point of the water; comprising: controlling the food processor with the main control chip 1 to heat the water inside the food processor with a heater in the heating chamber 2 while detecting variable temperatures of the water inside the food processor with a temperature sensor; when detecting the variable temperatures of the water reach the current boiling point of the water, the food processor is controlled to stop heating by the main control chip 1; characterized in that the external actions during the preset time period are user' touch operations on an operation sensing module, which can be an inductive circuit and virtual keys as combined, the virtual keys are visualized and shown on specific areas of the display screen. when the food processor is powered on, judging whether the food processor generates an enabled instruction for detecting a boiling point based on external actions during a preset time period; if the food processor generates the enabled instruction for detecting the boiling point based on external actions during the preset time period, a pre-stored process for detecting the boiling point is started by a process starting module 20, to obtain a current boiling point of water at the current location of the food processor; controlling the food processor to heat water inside the food processor based on the current boiling point of the water; if the food processer fails to generate the enabled instruction for detecting the boiling point based on external actions during the preset time period, controlling the food processer to heat water inside the food processor based on a pre-stored boiling point in the food processor, which is the current boiling point of the water; comprising: controlling the food processor with the main control chip 1 to heat the water inside the food processor with a heater in the heating chamber 2 while detecting variable temperatures of the water inside the food processor with a temperature sensor; when detecting the variable temperatures of the water reach the current boiling point of the water, the food processor is controlled to stop heating by the main control chip 1; characterized in that the external actions during the preset time period are user' touch operations on an operation sensing module, which can be an inductive circuit and virtual keys as combined, the virtual keys are visualized and shown on specific areas of the display screen. controlling the food processor with the main control chip 1 to heat the water inside the food processor with a heater in the heating chamber 2 while detecting variable temperatures of the water inside the food processor with a temperature sensor; when detecting the variable temperatures of the water reach the current boiling point of the water, the food processor is controlled to stop heating by the main control chip 1; characterized in that the external actions during the preset time period are user' touch operations on an operation sensing module, which can be an inductive circuit and virtual keys as combined, the virtual keys are visualized and shown on specific areas of the display screen.
