Embodiment Construction
[0059] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0060] In the actual use of the rice cooker, some users usually use hot water to cook rice. In this case, the temperature of the bottom of the rice cooker rises rapidly, the rice is not fully boiled, and the temperature of the bottom temperature sensor rapidly rises to 120°C , so that the rice cooker enters the stage of stewing rice prematurely, causing the rice to be undercooked. The method for controlling the heating temperature of the electric rice cooker provided by the present ...

The embodiment of the invention provides a rice cooker and a method and device for controlling the heating temperature of the rice cooker. The method comprises the following steps: determining whether the rice cooker is in a boiling stage or not according to the temperature of a bottom temperature-sensing bulb, at the same time, obtaining the temperature of the bottom temperature-sensing bulb and the temperature of a top temperature-sensing bulb; determining whether the temperature of the bottom of the rice cooker is raised too fast or not based on the two temperatures; if the temperature of the bottom of the rice cooker is raised too fast, controlling a heating plate to stop heating until the temperature of the bottom temperature-sensing bulb is reduced to a first preset temperature, and then controlling the heating plate to heat with the heating power in the boiling stage. It can be seen that when the temperature of the bottom of the rice cooker is determined to be raised too fast, heating of the bottom of the rice cooker is stopped, and when the temperature of the bottom of the rice cooker is reduced to the first preset temperature, heating is conducted. Therefore, rice in the rice cooker can be fully boiled; if the temperature of the bottom of the rice cooker is raised too fast, the rice is underdone since the rice enters a stewing stage without being sufficiently boiled, but for the provided rice cooker, the occurrence of such phenomenon can be avoided. The rice cooker allows the rice to be well-done and thus is more in line with the eating requirements of users.
Description
technical field [0001] The present application relates to the technical field of automatic control, and more specifically relates to a method and device for controlling the heating temperature of an electric rice cooker and an electric rice cooker. Background technique [0002] The cooking process of an electric rice cooker generally includes four stages: rice soaking-heating-boiling-simmering rice, and different heating powers are used in different stages. [0003] The bottom of the main body of the rice cooker is equipped with a bottom temperature sensor, which can sense the temperature of the bottom of the pot in real time. The controller can judge which stage the rice cooker is currently in by detecting the temperature of the bottom temperature sensor. For example, for a certain type of rice cooker, when the temperature of the bottom temperature sensor is < 60°, it is the rice soaking stage; when 60° ≤ the temperature of the bottom temperature sensor ≤ 80°, it is the ...
