Problems solved by technology

For this reason, some people add a composite bottom to the bottom of the stainless steel pot to conduct heat evenly, but this leads to a substantial increase in the cost of the stainless steel rice cooker and increases the cost of using the rice cooker.

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 As shown, when the electric rice cooker cooks rice by rated power, rated capacity or 90% close to the rated capacity, the temperature sensor installed in the round hole in the middle of the heating plate senses the temperature at the bottom of the pot. At the beginning of cooking rice, when the rice grains and water are not boiling, because the rice grains settle at the bottom of the pot to form a layer of rice grains, the heat conduction between the water in the upper part of the rice grain layer and the heating plate under the bottom of the pot is hindered, and the temperature of the water in the upper part of the pot is lower than The temperature under the layer of rice grains at the bottom of the pot. The temperature at the bottom of the pot detected by the temperature sensor rises with time. After the rice grains ...

Abstract

The invention discloses a control method of rice cooking by adopting an electric rice cooker with a stainless-steel inner container, for reducing the cost of a stainless-steel electric rice cooker and cooking rice very well. The control method comprises the following steps: a microprocessor selects time required by rise range of temperature of the bottom of the stainless-steel inner container, calculates the temperature-rise speed, and divides the heating time into heating time sections at 5-20 gears; when the heating time is reached, the heating stops for a period of time; when the temperature falls to a second temperature point, heating is continuously carried out, the time-interval heating mode is adopted; and after the temperature reaches a third temperature point, the rice cooking process is finished. Compared with the prior art, the control method has the advantages that microprocessor is adopted for realizing control in stages, so that rice in the rice cooker can not be burnt or undercooked when the stainless-steel inner container is heated, the stainless-steel inner container can be accurately controlled, the methods for the electric rice cooker to control different inner containers are increased, and the control accuracy is improved.

Description

technical field [0001] The invention relates to a control method for cooking rice in an electric rice cooker, in particular to a control method for cooking rice in an electric rice cooker with a inner liner of a stainless steel pot. Background technique [0002] Electric rice cooker brings convenience to people's life, and the method for prior art control electric rice cooker cooking rice adopts the temperature sensor installed in the circular hole in the middle of heating plate, as magnetic steel thermostat or negative temperature coefficient NTC thermostat. Sensitive resistance, set a fixed temperature value on the control circuit, such as 140 ° C, when the temperature sensor senses that the temperature is greater than or equal to this value, the control circuit cuts off the heating power supply and enters the heat preservation state. This control method is suitable for the inner tank of the aluminum pot . Stainless steel has good chemical stability, and more and more peo...
