Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The constant temperature control method of the oven provided by the embodiment of the application can be applied to the oven. As shown in fig. 1, the oven comprises a heating pipe 101, a temperature sensing probe 102 and an electric furnace main control board 103. And the heating pipe 101 is arranged above the top layer of the oven and connected with the electric furnace main control board 103 and is used for heating the oven. The temperature sensing probe 102 is arranged at the junction position behind and above the oven cavity and is connected with the electric furnace main control board 103 through an electric signal for detecting the temperature in the oven. The electric furnace main control board 103 is arranged above the heating pipe 101 and is respectively connected with the heating pipe 101 and the temperature sensing probe 102 and is used for acquiring an oven temperature sequence detected by the temperature sensing probe 102 in the oven heating process in the current constant temperature control period. The electric furnace main control board 103 determines the predicted maximum oven temperature of the oven after stopping heating according to the oven temperature sequence and the heat preservation time length corresponding to the current constant temperature control period. If the predicted maximum oven temperature is greater than or equal to the target heating temperature preset by the user, the electric furnace main control board 103 controls the heating pipe 101 to stop heating, and obtains the actual maximum oven temperature detected by the temperature sensing probe 102 in the process of stopping heating of the oven in the current constant temperature control period. The electric furnace main control board 103 determines the heat preservation time length corresponding to the next constant temperature control period according to the actual maximum oven temperature, the target heating temperature, the heat preservation time length corresponding to the current constant temperature control period and the preset heat preservation time length adjustment coefficient. When the current oven temperature is less than or equal to the lower limit temperature corresponding to the target heating temperature, entering the next constant temperature control period, controlling the heating pipe 101 by the electric furnace main control board 103 to restart heating, and executing the step of acquiring the oven temperature sequence in the oven heating process detected by the temperature sensing probe 102 in the current constant temperature control period until the heating duration reaches the target heating duration preset by a user.
The following will describe a detailed description of a method for controlling a constant temperature of an oven according to an embodiment of the present application with reference to a specific embodiment, and fig. 2 is a flowchart of a method for controlling a constant temperature of an oven according to an embodiment of the present application, and as shown in fig. 2, specific steps are as follows:
step 201, acquiring an oven temperature sequence in the heating process of the oven in the current constant temperature control period.
In the implementation, in order to ensure continuous heating within the target heating time preset by the user, the electric furnace main control board divides the target heating time preset by the user into a plurality of constant temperature control periods and controls the temperature in the oven to keep constant temperature heating within each constant temperature control period. Because the electric furnace main control board needs to perform constant temperature control on the temperature in the oven, the electric furnace main control board needs to acquire an oven temperature sequence in the heating process of the oven in the current constant temperature control period, and the electric furnace main control board performs constant temperature control according to the oven temperature sequence in the subsequent steps. The oven temperature sequence may be an ordered sequence of temperature values labeled according to the size of the sampling time.
Step 202, determining the predicted maximum oven temperature of the oven after stopping heating according to the oven temperature sequence and the heat preservation time length corresponding to the current constant temperature control period.
In practice, in the prior art, when the oven is used for heating food at a constant temperature, when the temperature in the oven reaches a target heating temperature preset by a user, the heating pipe is powered off, and when the temperature in the oven is gradually cooled, the heating pipe is powered on again for heating. However, when the temperature of the oven reaches the target heating temperature preset by the user, after the heating pipe is powered off, the residual temperature of the heating pipe can cause the actual temperature in the oven to exceed the target heating temperature preset by the user, so that the food material is overheated and heated. In order to avoid the situation, in each constant temperature control period, starting from heating of the heating pipe, the main control board of the electric furnace controls the temperature sensing probe to detect the temperature sequence of the oven in real time, and predicts the maximum oven temperature which can be reached by the oven according to the heat preservation period and the oven temperature sequence corresponding to the current constant temperature control period after heating of the heating pipe is stopped at the current temperature, and the residual temperature of the heating pipe is relied in the heat preservation period. The first thermostatic control period corresponds to a preset duration of heat preservation, typically 300 seconds. The subsequent heat preservation time period corresponding to each constant temperature control period can be adjusted according to the predicted maximum oven temperature, the actual maximum oven temperature and the target heating temperature of the previous constant temperature control period. In this way, the actual maximum oven temperature of each constant temperature control period is gradually equal to the target heating temperature, so that accurate control of the temperature in the oven is realized. The treatment process of adjusting the thermal insulation time length corresponding to each subsequent constant temperature control period according to the predicted maximum oven temperature, the actual maximum oven temperature and the target heating temperature of the previous constant temperature control period will be described in detail later, and will not be described here.
As an alternative implementation manner, the treatment process of the oven for predicting the maximum oven temperature after the electric furnace main control board determines to stop heating according to the oven temperature sequence and the heat preservation time length corresponding to the current constant temperature control period is as follows.
Step one, determining the current temperature rising rate according to an oven temperature sequence.
In practice, the rate of temperature rise of the oven temperature within the oven is determined by the temperature of the heating tube during heating of the heating tube. After the heating pipe is stopped for heating, the residual temperature of the heating pipe gradually decreases, and correspondingly, the temperature rising rate of the oven temperature in the oven gradually decreases along with the residual temperature of the heating pipe within the heat preservation time period, and the current temperature rising rate (namely the temperature rising rate when the heating pipe is stopped for heating) gradually decreases. Therefore, in the current constant temperature control period, the electric furnace main control board can calculate the current heating rate according to the obtained oven temperature sequence, and then determine the predicted maximum oven temperature in the oven based on the current heating rate.
As an alternative implementation manner, the formula for determining the current heating rate of the main control board of the electric furnace according to the temperature sequence of the oven is as follows:
Where k represents the current temperature increase rate, T1 represents the average oven temperature in 1 second before 1 second, T2 represents the average oven temperature in 1 second before 2 seconds, Ti represents the average oven temperature in 1 second before i seconds, Ti+1 represents the average oven temperature in 1 second before (i+1) seconds, Ti+2 represents the average oven temperature in 1 second before (i+2) seconds, T2i represents the average oven temperature in 1 second before 2i seconds, and i represents the number of seconds.
Further, when the oven temperature in the oven temperature sequence is updated and changed, the main control board of the electric furnace recalculates the current heating rate so as to ensure that the current heating rate is always the heating rate corresponding to the maximum sampling time in the oven temperature sequence.
And step two, determining the predicted maximum oven temperature of the oven after stopping heating according to the current heating rate, the heat preservation time corresponding to the current constant temperature control period, the heating rate attenuation coefficient preset by a user and the oven temperature corresponding to the maximum sampling time in the oven temperature sequence.
In implementation, after heating of the heating pipe is stopped, the residual temperature of the heating pipe gradually decreases, correspondingly, the temperature rising rate of the oven temperature in the oven gradually decreases along with the residual temperature of the heating pipe within the heat preservation period, the current temperature rising rate (namely, the temperature rising rate when heating of the heating pipe is stopped) gradually decays, and the current temperature rising rate multiplied by the temperature rising rate decay coefficient can be used for representing the overall temperature rising rate of the oven temperature under the influence of the residual temperature of the heating pipe within the whole heat preservation period. The temperature rise rate attenuation coefficient is measured according to experiments, and the value range is between (0 and 1), and is usually 0.5. Therefore, after the oven stops heating, the main control board of the electric furnace determines the predicted maximum oven temperature of the oven after heating is stopped according to the current heating rate, the heat preservation time corresponding to the current constant temperature control period, the heating rate attenuation coefficient preset by a user and the oven temperature corresponding to the maximum sampling time in the oven temperature sequence. Therefore, after the oven stops heating, the electric furnace main control board calculates the predicted maximum oven temperature for heating the food by means of the residual temperature of the heating pipe, so that the electric furnace main control board is more accurate and is more fit with the actual temperature.
As an optional implementation manner, the formula for determining the predicted maximum oven temperature of the oven after stopping heating according to the current heating rate, the heat preservation time corresponding to the current constant temperature control period, the heating rate attenuation coefficient preset by the user and the oven temperature corresponding to the maximum sampling time in the oven temperature sequence by the electric furnace main control board is as follows:
T0'＝T1+nk×t
wherein, T0' represents the predicted maximum oven temperature, T1 represents the average oven temperature within 1 second before 1 second, n represents the heating rate attenuation coefficient preset by the user, k represents the current heating rate, and T represents the heat preservation time corresponding to the current constant temperature control period.
And 203, if the predicted maximum oven temperature is greater than or equal to the target heating temperature preset by the user, stopping heating, and acquiring the actual maximum oven temperature in the heating stopping process of the oven in the current constant temperature control period.
In the implementation, the electric furnace main control board compares the calculated predicted maximum oven temperature with the target heating temperature preset by the user, and if the predicted maximum oven temperature is greater than or equal to the target heating temperature preset by the user, the electric furnace main control board controls the heating pipe to stop heating at the moment, and the oven temperature can reach the target heating temperature preset by the user by depending on the residual temperature of the heating pipe, so that overheating heating of the food by the oven is avoided. At this time, the electric furnace main control board controls the heating pipe to stop heating. In order to ensure that the actual maximum oven temperature in the oven can reach the target heating temperature preset by a user within the heat preservation time after the heating pipe is stopped, the electric furnace main control board continuously obtains the actual maximum oven temperature in the oven through the temperature sensing probe in the process of stopping heating the oven within the current constant temperature control period.
Further, if the predicted maximum oven temperature is less than the target heating temperature preset by the user, the step of acquiring an oven temperature sequence in the oven heating process in the current constant temperature control period is executed.
In the implementation, the electric furnace main control board compares the calculated predicted maximum oven temperature with a target heating temperature preset by a user, and if the predicted maximum oven temperature is smaller than the target heating temperature preset by the user. If the oven is powered off at the moment, the predicted maximum oven temperature which can be reached by the oven cannot reach the target heating temperature preset by a user by means of the residual temperature of the heating pipe. That is, the food cannot be heated at a constant temperature according to the target heating temperature preset by the user. Therefore, the main control board of the electric furnace needs to control the heating pipe to continue heating. Correspondingly, the main control board of the electric furnace executes the step of acquiring the oven temperature sequence in the heating process of the oven in the current constant temperature control period.
Step 204, determining the heat preservation time length corresponding to the next constant temperature control period according to the actual maximum oven temperature, the target heating temperature, the heat preservation time length corresponding to the current constant temperature control period and the preset heat preservation time length adjustment coefficient.
In practice, the actual maximum oven temperature of the oven may be greater than, equal to, or less than the target heating temperature during the period after the oven has stopped heating. When the actual maximum oven temperature is equal to the target heating temperature, the heat preservation duration corresponding to the current constant temperature control period is proper, and the adjustment of the heat preservation duration corresponding to the next constant temperature control period is not needed (namely, the heat preservation duration corresponding to the next constant temperature control period is equal to the heat preservation duration corresponding to the current constant temperature control period). If the actual maximum oven temperature is greater than the target heating temperature, the fact that the heat preservation duration corresponding to the current constant temperature control period is too long is indicated, and the electric furnace main control board needs to adjust the heat preservation duration corresponding to the next constant temperature control period (namely, reduce the heat preservation duration corresponding to the next constant temperature control period) according to the actual maximum oven temperature, the target heating temperature, the heat preservation duration corresponding to the current constant temperature control period and the preset heat preservation duration adjustment coefficient, so that the actual maximum oven temperature is only closer to the target heating temperature preset by a user under the heat preservation duration corresponding to the next constant temperature control period. If the actual maximum oven temperature is smaller than the target heating temperature, the fact that the heat preservation time length corresponding to the current constant temperature control period is too small is indicated, and the electric furnace main control board needs to adjust the heat preservation time length corresponding to the next constant temperature control period (namely, increase the heat preservation time length corresponding to the next constant temperature control period) according to the actual maximum oven temperature, the target heating temperature, the heat preservation time length corresponding to the current constant temperature control period and the preset heat preservation time length adjustment coefficient, so that the actual maximum oven temperature is only closer to the target heating temperature preset by a user under the heat preservation time length corresponding to the next constant temperature control period. The preset heat preservation time length adjustment coefficient is measured according to experiments, and is usually 5.
As an optional implementation manner, according to the actual maximum oven temperature, the target heating temperature, the heat preservation duration corresponding to the current constant temperature control period and the preset heat preservation duration adjustment coefficient, the formula for determining the heat preservation duration corresponding to the next constant temperature control period is as follows:
t’=t-[Tm-T0]*m
wherein T' represents the heat preservation time length corresponding to the next constant temperature control period, T represents the heat preservation time length corresponding to the current constant temperature control period, tm represents the actual maximum oven temperature, T0 represents the target heating temperature, the symbol [ ] represents rounding the values in brackets, and m represents the preset heat preservation time length adjustment coefficient.
During the period after the oven stops heating, the actual maximum oven temperature in the oven may be greater than, equal to, or less than the target heating temperature. When the actual maximum oven temperature in the oven is greater than the target heating temperature, the formula T' =tTm-T0 represents that the difference between the actual maximum oven temperature and the target heating temperature is a positive number, and the product of the difference between the actual maximum oven temperature and the target heating temperature and the heat preservation time length adjustment coefficient is also a positive number. Subtracting a positive number from the heat preservation time corresponding to the current constant temperature control period to obtain the heat preservation time corresponding to the next constant temperature control period, wherein the heat preservation time corresponding to the next constant temperature control period is reduced compared with the heat preservation time corresponding to the current constant temperature control period. Thus, when the actual maximum oven temperature in the oven is greater than the target heating temperature, the corresponding holding time period of the next constant temperature control period is reduced. In this way, the actual maximum oven temperature for the next thermostatic control cycle is closer to the target heating temperature preset by the user.
When the actual maximum oven temperature in the oven is equal to the target heating temperature, the expression T' =tTm-T0 represents that the difference between the actual maximum oven temperature and the target heating temperature is zero, and the product of the difference between the actual maximum oven temperature and the target heating temperature and the thermal insulation duration adjustment coefficient is zero. Subtracting one zero from the heat preservation time length corresponding to the current constant temperature control period to obtain the heat preservation time length corresponding to the next constant temperature control period, and indicating that the heat preservation time length corresponding to the next constant temperature control period is equal to the heat preservation time length corresponding to the current constant temperature control period. That is, when the actual maximum oven temperature in the oven is equal to the target heating temperature, the heat-preserving period does not need to be adjusted, and the heat-preserving period corresponding to the next constant-temperature control period is also equal to the heat-preserving period corresponding to the current constant-temperature control period.
When the actual maximum oven temperature in the oven may be less than the target heating temperature, the expression T' =tj- [ Tm-T0] is expressed as meaning that the difference between the actual maximum oven temperature and the target heating temperature is negative, and the product of the difference between the actual maximum oven temperature and the target heating temperature and the holding time length adjustment coefficient is also negative. Subtracting a negative number from the heat preservation time corresponding to the current constant temperature control period to obtain the heat preservation time corresponding to the next constant temperature control period, which indicates that the heat preservation time corresponding to the next constant temperature control period is longer than the heat preservation time corresponding to the current constant temperature control period. Thus, when the actual maximum oven temperature in the oven is smaller than the target heating temperature, the corresponding heat preservation time length of the next constant temperature control period is increased. In this way, the actual maximum oven temperature for the next thermostatic control cycle is closer to the target heating temperature preset by the user.
Step 205, when the current oven temperature is less than or equal to the lower limit temperature corresponding to the target heating temperature, entering the next constant temperature control period, restarting heating, and executing the step of acquiring an oven temperature sequence in the oven heating process in the current constant temperature control period until the heating duration reaches the target heating duration preset by the user.
In the implementation, the temperature sensing probe detects the temperature in the oven in real time within the target heating duration preset by the user. When the current oven temperature in the oven is less than or equal to the lower limit temperature corresponding to the target heating temperature, entering the next constant temperature control period, controlling the heating pipe by the electric furnace main control board to restart heating, and executing the step of acquiring the oven temperature sequence in the oven heating process in the current constant temperature control period until the heating duration reaches the target heating duration preset by a user. The lower limit temperature is preset by a user, and optionally, the lower limit temperature may be 20 degrees. In this way, it is ensured that the temperature does not have to drop to zero to start reheating, nor is it significantly different from the target heating temperature.
The embodiment of the application provides a constant temperature control method of an oven, which divides constant temperature control periods for target heating temperature preset by a user, and updates the heat preservation duration of each constant temperature control period to ensure that the actual maximum oven temperature in the heating stopping process of the oven is equal to the target heating temperature preset by the user. Therefore, the problems that the actual temperature in the oven exceeds the target heating temperature preset by a user and the constant temperature is inaccurate can be avoided, and the accurate control of the temperature in the oven is realized.
