The invention provides a method and device for controlling a household oil press and the household oil press. The method for controlling the household oil press includes the steps of acquiring corresponding optimum oil pressing temperatures of oil pressing materials, controlling heater strips to heat a barrel, detecting temperature in the barrel in real time, and controlling the difference value between the temperature in the barrel and the optimum oil pressing temperatures to be within a preset range. According to the technical scheme, the optimum oil pressing temperatures of the different oil pressing materials are required, and the temperatures of the oil pressing materials are stabilized within the range of the optimum oil pressing temperature in the oil pressing process, so that stability of the oil yield of the oil pressing materials is guaranteed, the phenomenon that the oil yield is unstable because the different oil pressing materials are pressed at the same temperature is avoided, fluency of the oil pressing process of a motor is guaranteed, and the problem that in the prior art, the oil yield of the household oil press is unstable is solved.
