Electric pressure cooker and its cooking control method and cooking control device

Abstract

The invention discloses an electric pressure cooker, as well as a cooking control method and cooking control device thereof. The method comprises the following steps: detecting upper cover temperatureof the electric pressure cooker in real time so as to generate an upper cover temperature sampled value; acquiring the states of a pressure switch in the electric pressure cooker, wherein the pressure switch gets connected or disconnected in accordance with pressure in the electric pressure cooker; controlling the electric pressure cooker to conduct heating by a first power adjusting ratio; and sampling the upper cover temperature sampled value when the pressure switch is disconnected to serve as a standard sampled value, and controlling the electric pressure cooker to conduct heating by a second power adjusting ratio in accordance with the standard sampled value; therefore cooking processes of the electric pressure cooker can be controlled in accordance with the states of the pressure switch, so that the product (the electric pressure cooker) can adapt to working environments of different altitudes, such problems as spillover and the like of the electric pressure cooker caused by pressing deviation can be prevented, a cooking effect can be improved, product competitiveness can be improved and user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a cooking control method for an electric pressure cooker, a cooking control device for the electric pressure cooker and an electric pressure cooker. Background technique [0002] The electric pressure cooker in the related art usually sets a preset pressure and performs pressure control by detecting the temperature of the upper cover, that is, when the sampling value of the upper cover temperature reaches the first preset upper cover temperature sampling value, the electric pressure cooker is controlled to stop heating. When the sampled value is lower than the second preset upper cover temperature sampled value, the electric pressure cooker is controlled to start heating, so that the pressure in the pot is maintained at the preset pressure. However, the disadvantage of the related technology is that the preset upper cover temperature sampling value is a fixed value, ...

AI Technical Summary

Problems solved by technology

However, the disadvantage of the related technology is that the preset upper cover temperature sampling value is a fixed value, and when the electric pressure cooker is used in the plateau area, due to the lower boiling point of water, the corresponding upper cover temperature sampling value decreases when the preset pressure is reached. As a result, the control pressure of the electric pressure cooker is higher than the actual value, and the electric pressure cooker may have risks such as overflow
