Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application shall fall within the scope of protection of the present application.
The application provides an intelligence temperature control electricity rice cooker, please refer to and draw together 1, intelligence temperature control electricity rice cooker includes electric rice cooker main part 1 and electric rice cooker lid 2, settle non-contact temperature sensor 3 in the electric rice cooker lid 2, wherein:
the non-contact temperature sensor 3 is used for monitoring the temperature in the electric cooker in real time in the working process of the electric cooker;
the intelligent temperature control electric cooker is used for judging the proportion of water and rice in the electric cooker according to the temperature monitored in real time and adjusting the heating temperature according to the judged proportion.
In practical application, the non-contact temperature sensor can perform radiation temperature measurement based on the basic law of blackbody radiation, and can perform correction on the surface emissivity of the material before use. The surface emissivity of a material depends not only on temperature and wavelength, but also on the surface state, coating film, microstructure, and the like. For automatic measurement and control of the solid surface temperature, additional mirrors may be used to form the hohlraum with the measured surface. The most typical additional mirror is a hemispherical mirror, and diffuse radiation energy from the surface under test near the center of the sphere is reflected back to the surface by the hemispherical mirror to form additional radiation.
In one embodiment, the determining the ratio of water and rice in the rice cooker according to the temperature monitored in real time comprises:
if the monitored temperature is lower than 100 ℃, determining that the water level is higher than the position of a meter;
and if the monitored temperature is higher than 100 ℃, determining that the water level is lower than the position of rice.
In practical application, the heating temperature of the electric cooker can be dynamically adjusted according to the proportion of water to rice. For example, when the water level is above the meter, the heating temperature may be slightly higher, and when the water level is below the meter, the heating temperature may be lower.
In one embodiment, the intelligent temperature control electric cooker monitors the temperature in the electric cooker in real time when cooking soup, judges the heating medium in the electric cooker according to the real-time monitored temperature, and identifies whether the heating medium in the electric cooker is burnt dry or not according to the judged heating medium and the current temperature.
Specifically, according to the temperature of real-time supervision, judge the heating medium in the electricity rice cooker and include:
monitoring the change value of the temperature, identifying the target temperature interval when the temperature is within the target temperature interval within the preset time, and taking the heating medium corresponding to the target temperature interval as the heating medium in the electric cooker.
For example, if the target temperature range is 105 ℃ to 115 ℃, determining that the heating medium is water; and if the target temperature interval is more than 200 ℃, judging that the heating medium is oil.

if the temperature exceeds the target temperature interval, monitoring the temperature rise speed of the temperature; and if the monitored temperature rise speed is higher than the average temperature rise speed, judging that the heating medium in the electric cooker is burnt out.
For example, if water is in the pot, the temperature difference between the inside and the outside of the pot is about 10 degrees. When the water is boiled, the temperature in the pot is 95-100 ℃ (the boiling temperature of the water is related to the air pressure), the temperature of the outer surface of the pot is maintained at 105-115 ℃, and the temperature of the pot body can be rapidly increased until the water in the pot is dried. If the oil is in the pot, the temperature of the pot body can be continuously raised to 200 ℃ or even higher. The rate of temperature rise when there is oil in the pan will be slower than when the pan is dry.
