Electric pressure cooker and control method for electric pressure cooker

Abstract

The invention provides a control method for an electric pressure cooker. The electric pressure cooker is provided with a heater and a pressure valve. The control method comprises the boiling point detection step of detecting the boiling point temperature Kf inside the electric pressure cooker and determining the pressure control pressure and the active exhaust pressure of the electric pressure cooker according to the boiling point temperature Kf, and the cooking step of detecting the steaming temperature inside the electric pressure cooker and controlling heating of the heater and opening and closing of the pressure valve according to the steaming temperature, the pressure control pressure and the active exhaust pressure. According to the control method for the electric pressure cooker, due to the facts that the boiling point temperature inside the electric pressure cooker is detected before cooking, and the pressure control pressure and the active exhaust pressure of the electric pressure cooker are adjusted according to the boiling point temperature, the control method for the electric pressure cooker has the advantages that food is prevented from overflowing when the food is cooked in a high altitude area, and the food is prevented from being undercooked when the food is cooked in a negative altitude area. The invention further provides the electric pressure cooker.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to an electric pressure cooker control method and the electric pressure cooker. Background technique [0002] With the enrichment of people's material life and the improvement of the quality of life, higher requirements are placed on the control and applicability of cooking utensils. [0003] The pressure control methods of electric pressure cookers in the prior art are divided into two types. One is to control the pressure through a pressure switch. The (heater) moves downwards to trigger the on-off of the pressure switch, which can adapt to the use requirements of different altitudes. The other is to measure the steam temperature in the electric pressure cooker through a temperature sensor, and control the pressure through the corresponding relationship between steam temperature and pressure, and use the temperature sensor to measure the steam temperature...

AI Technical Summary

Problems solved by technology

[0004] The control methods of the electric pressure cookers of the above two technologies have the following disadvantages: the first control method can only control the on-off of one kind of pressure, that is, single-point control of pressure, and cannot realize multi-stage pressure control, and cannot satisfy consumers’ needs for multiple pressures. cooking needs

The second control method uses the absolute temperature point to control the working pressure of the product. Due to the difference in altitude, the boiling point of water is also different. Therefore, at the same temperature in the pot, the corresponding pressure in the pot is different. Therefore, when cooking at a high altitude, it is easy to cause the cooked food to overflow, and when cooking at a negative altitude, it is easy to cause the water to not boil and the cooked food to be undercooked, etc.
