Heating boiler temperature control system and method

Abstract

The invention discloses a heating boiler temperature control system and method. The heating boiler temperature control method comprises the following steps of controlling a heating plate to perform heating through a control mainboard and receiving the inner surface temperature of an inner tank and the surface temperature of the heating plate timely, wherein the inner surface temperature of the inner tank is detected by a first temperature sensor and the surface temperature of the heating plate is detected by a second temperature sensor; controlling the heating plate to stop heating when the inner surface temperature of the inner tank is detected to reach a preset value for the first time; performing real-time calculation on a temperature deviation value of the surface temperature of the heating plate and the inner surface temperature of the inner tank at the next moment through the control mainboard and judging whether the inner surface temperature of the inner tank is located in the preset standard range or not and whether the temperature deviation value is within the temperature difference threshold range or not; controlling the heating plate to maintain the current heating temperature if yes. According to the heating boiler temperature control system and method, the temperature difference control is performed on the inner surface temperature of the inner tank, the surface temperature of the heating plate and the temperature deviation value and accordingly the accurate feedback control can be achieved, the locking of the temperature of the inner tank can be guaranteed, the inner tank can enter into the constant temperature state rapidly, and meanwhile the energy consumption is saved.

Description

technical field [0001] The invention relates to the field of household appliance manufacturing, in particular to a heating pot temperature control system and method. Background technique [0002] At present, heating pots are widely used to meet people's cooking requirements for different ingredients (including water, etc.) (such as stewing, boiling, steaming, frying, roasting, etc.). ; For example, when steaming rice, how to achieve constant temperature control of the inner rice in the inner tank is the most important; for example, the best temperature for steaming rice (such as millet) is 50 degrees, that is, keep the inner surface temperature of the inner tank at 50 degrees for a long time If this is the case, it can guarantee the completion of steaming and cooking rice in the fastest time, and at the same time, it will not cause waste of energy (electric energy or gas energy). [0003] However, the existing constant temperature control is single-temperature control, that...

[0005] However, the existing constant temperature control is single-temperature control, that is, it can only rely on detecting the temperature of the bottom of the pot (that is, the heating plate), and then use empirical data to control the power of the heating plate to achieve the so-called “temperature balance”. At this time, the temperature of the inner pot The fluctuation is relatively large, and it does not meet the real temperature equilibrium conditions

When electric frying pans, including those used in induction cookers, are working, the temperature on the inner surface is also very uneven, and the temperature in the middle circle is often very high. Therefore, single temperature control is difficult to ensure the optimum temperature requirements for frying peanuts, which will eventually affect the taste.
