Electric cooker and heat preservation method thereof

Abstract

The invention provides an electric cooker and a heat preservation method thereof. The heat preservation method of the electric cooker comprises the following steps that: a control unit receives a preset heating mode selected by the user from multiple preset heating modes; a temperature detection unit obtains the temperature of a heating area in a liner; and a control unit receives the temperature of the heating area, and controls the heating device according to the preset heating mode selected by the user to preserve heat of the food contained in the liner according to the preset heat preservation curve. According to the invention, the heating device is controlled according to the heat preservation mode selected by the user to preserve heat of the food contained in the liner according to the preset heat preservation curve, the heat preservation needs for different functions can be met, and the heat preservation temperature is dynamically set according to the external input and the conditions in the electric cooker so as to solve the problem that the electric cooker of the prior art cannot dynamically set the heat preservation temperature according to the conditions inside and outside.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to an electric rice cooker and a heat preservation method thereof. Background technique [0002] At present, the rice cookers sold in China have only one "heat preservation" file, and the heat preservation range is 60°C-80°C. figure 1 A schematic diagram of a heat preservation curve of an electric rice cooker in the prior art is shown. Such as figure 1 As shown, when the electric rice cooker in the prior art finishes cooking and other operations, the heat preservation temperature can only be stabilized at a certain fixed value. Therefore, when the heat preservation time is longer, it may cause food deterioration. [0003] However, although foreign rice cookers have two levels of heat preservation, high temperature heat preservation and low temperature heat preservation, they can only be used for rice heat preservation, and the heat preservation process is relatively unchanged, tha...
