Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In order to describe the technical principle, technical scheme and technical effect of the dry burning prevention protection method in detail, a dry burning prevention scene of a gas stove is taken as an example, and related prior art and significant improvements made on the basis of the prior art in the application are described in detail below.
As shown in figure 1, the temperature change of the gas stove during water boiling is schematically shown, and the whole process has three stages, wherein I is a rapid temperature rise stage, and the temperature rise speed is higher because the flame temperature of the gas stove is higher, the temperature difference between the flame temperature and the bottom of a pot is larger, the temperature rise is easier and the temperature rise speed is higher. And II, a stable working stage, wherein the water in the pot is boiled, the temperature of the pot bottom is stable, and the fluctuation is small. And III, a stage of dry heating, wherein water in the pot is already heated to be dry, the flame heats the pot bottom all the time, the temperature of the pot bottom rises rapidly to reach more than 300 ℃, and therefore dry heating prevention protection is triggered.
The traditional common utensils (cookware) are made of iron, stainless steel, copper, ceramics, glass, alloy and the like. Because the heat conductivity coefficients of different materials are different, the specific heat capacities are different, and the temperature curves of the reaction in the water boiling process are different. For example, copper has a thermal conductivity of about 337W/m.K and a specific heat capacity of 0.386 kJ/kg.K; the thermal conductivity of the aluminum is about 230W/m.K, and the specific heat capacity is 0.905 kJ/kg.K; the heat conductivity coefficient of the stainless steel is about 16W/m.K, and the specific heat capacity is 0.465 kJ/kg.K; the heat conductivity coefficient of the glass is 1.09W/m.K, the specific heat capacity is 0.75 kJ/kg.K, the larger the heat conductivity coefficient is, the better the heat conductivity is, and the lower the temperature of the pot bottom in the stable working stage II is when the reaction is on a temperature change curve; the larger the specific heat capacity is, the better the heat storage performance is, in the stage of I rapid heating up, the temperature rise is slower, in the stage of III dry burning, after the dry burning prevention protection is started, the temperature of the pot bottom is reduced slower, the temperature change and the time length of the pot bottom are tested by a dry burning prevention temperature probe which mainly depends on the measurement temperature, and the current state is judged according to the temperature rise rate (s/DEG C). For example, under national standard test conditions, with a gas range of some 5.0kW heat load, heating 10kg of water, taking about 921 seconds from 25 ℃ to 75 ℃, the rate of temperature rise is 18.4 s/deg.c, which is now part of the first stage; the second stage is to maintain the water in a boiling state, generally about 98-100 ℃, wherein the temperature change is basically not generated, the temperature rise rate is extremely low, and the temperature rise rate can be regarded as ∞ s/DEG C until the water is dried. The third stage is that the water is not in the pot, the temperature of the bottom of the pot rises very fast, and the temperature rise rate can reach 1.5 s/DEG C or less.
The intensive research finds that the numerical value of the temperature rise rate at each stage is uncertain due to various factors such as different pots used in the test, different gas stove performances, different water in the pots and the like. However, it can be considered that the current stage is distinguished by the change of the temperature rise rate values which are relatively obvious in the 3 different stages, and then the dry burning prevention parameters (temperatures) corresponding to different types of pots are determined, so that accurate dry burning prevention protection is realized.
The scheme of the dry burning prevention protection method is provided after the above-mentioned intensive research on the prior art, and can be specifically applied to the application environment (gas stove) in fig. 2, the gas stove specifically collects the temperature of the appliance to be protected (indicated by a pot in fig. 2) in a dry burning prevention test state in real time to obtain real-time temperature data, the pot contains a standard amount of water, for example, 100ml of water, the real-time temperature data is matched and compared in a preset database to determine a target dry burning prevention parameter corresponding to the appliance to be protected, and the dry burning prevention protection is performed on the appliance to be protected according to the target dry burning prevention parameter.

The different types of implements may in particular be differently sized, shaped implements made of different materials. The dry burning prevention parameters mainly comprise dry burning prevention critical temperature corresponding to the dry burning occurrence time, and when the dry burning prevention critical temperature exceeds the dry burning prevention critical temperature, the dry burning occurrence condition of the appliance is indicated, and at the moment, the heating is required to be stopped. If not necessary, the dry burning prevention test can be performed on different types of appliances in advance, and the temperature data and the dry burning prevention parameters corresponding to the different types of appliances are obtained.
And matching and comparing the real-time temperature data in a preset database to search the matched temperature data in the preset database so as to obtain the dry burning prevention parameter corresponding to the temperature data, namely obtaining the target dry burning prevention parameter corresponding to the appliance to be protected. Specifically, the temperature data can be represented by temperature curves, the real-time temperature data is drawn into a real-time temperature curve, the temperature data stored in the preset database is represented by a plurality of temperature curves, the real-time temperature curve is matched and compared with the plurality of temperature curves in the preset database, the matched temperature curve is found, and then the dry burning prevention parameter corresponding to the found temperature curve is obtained.
S600: and performing dry burning prevention protection on the appliance to be protected according to the target dry burning prevention parameter.
The target dry burning prevention parameter mainly comprises dry burning prevention critical temperature, and when the dry burning prevention critical temperature is reached, heating is stopped so as to realize dry burning prevention protection on the appliance to be protected. Specifically, the gas stove detects the temperature of the appliance A in real time, and when the temperature of the appliance A reaches the dry burning prevention critical temperature corresponding to the target dry burning prevention parameter, the gas stove starts the dry burning prevention protection function and stops heating the appliance A.
Specifically, the gas stove has built-in general anti-dry-burning protection parameters, and can be used without parameter calibration. However, because different pots are used by users, the weight of each cooking or water heating is different, and the situation of delayed protection or early protection may exist, in order to implement the dry burning prevention protection more accurately, the dry burning prevention test state is added in the above processing, the target dry burning prevention parameter corresponding to the appliance to be protected is obtained in the dry burning prevention test state, the target dry burning prevention parameter can be written into the gas stove after being determined, and the dry burning prevention test state is ended. It can be understood that, in the above-mentioned dry combustion prevention test state, the judgment of the appliance type may be to determine the information of the cookware commonly used by the user through the temperature information collection and the temperature rate and temperature curve comparison after entering the dry combustion prevention test state, and update the dry combustion prevention protection parameter built in the gas stove, and the final purpose is to make better dry combustion prevention protection when the user is in subsequent normal use.
The anti-dry heating protection method comprises the steps of collecting the temperature of an appliance to be protected in an anti-dry heating test state in real time to obtain real-time temperature data, wherein the anti-dry heating test state refers to a state that the appliance is continuously heated when the appliance is filled with a preset standard amount of heating evaporable substances, matching and comparing the real-time temperature data in a preset database, determining a target anti-dry heating parameter corresponding to the appliance to be protected, and carrying out anti-dry heating protection on the appliance to be protected according to the target anti-dry heating parameter.
