Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
The embodiment of the invention provides a control method of a steaming and baking oven, which is shown in fig. 1. The control method of the steaming and baking oven comprises the following steps:
step 101, acquiring a first detection temperature acquired by a temperature sensor arranged at a first position in the steaming and baking oven.
And 102, according to the first detection temperature, carrying out temperature and humidity calibration on a humidity sensor arranged at a second position in the steaming oven in combination with an operation mode of the steaming oven to obtain a second detection temperature at the second position.
Step 103, judging whether the humidity sensor arranged at the second position is in an available state according to the second detection temperature.
104, if the humidity sensor is in an available state, controlling the humidity in the steaming and baking oven according to the humidity detection value of the humidity sensor; and if the humidity sensor is in an unavailable state or a fault state, controlling the humidity in the steaming and baking oven according to the humidity setting gear.
The humidity setting gear is a gear set by a user or a humidity setting gear pre-implanted in the intelligent menu. Specifically, the user can set a humidity setting gear according to the humidity in the steaming oven which is needed to be achieved. The humidity setting gear is positively correlated with the desired achieved humidity. If the humidity required to be achieved by the user is high, setting a high humidity setting gear; otherwise, if the humidity required to be achieved by the user is smaller, setting a lower humidity setting gear. The user may also set the gear using the humidity pre-embedded in the smart recipe. The pre-implanted humidity setting gear in the smart recipe is typically set based on the optimal humidity of the food.
It should be noted that, because the temperature sensor and the humidity sensor are respectively disposed at different positions, the detected temperatures at the first position and the second position will be different, and the humidity sensor can effectively collect humidity data only when the detected temperature at the second position exceeds the temperature threshold. Therefore, in order to improve the accuracy of the humidity sensor, the humidity sensor needs to be calibrated to obtain the detected temperature at the second location, that is, the detected temperature at the humidity sensor.
The humidity sensor is in a usable state, and the humidity detection value of the humidity sensor is reliable and accurate, so that the humidity in the steaming and baking oven is controlled according to the humidity detection value, and the purpose of accurately controlling the humidity is achieved. Otherwise, the humidity sensor is in an unavailable state or a fault state, and the humidity detection value of the humidity sensor cannot accurately represent the humidity in the steaming and baking oven, so that the humidity in the steaming and baking oven is controlled according to the set humidity setting gear, and the humidity in the steaming and baking oven is prevented from being controlled according to the humidity sensor in the fault state.
In this embodiment, through humidity transducer real-time detection evaporates the interior humidity content change of oven, combine evaporate the running mode of oven and carry out the humiture calibration to humidity transducer, according to humidity transducer's humidity detection value control evaporates the interior humidity of oven, make the cavity satisfy the required humidity of food culinary art in-process, realize the accurate control of culinary art in-process humidity, guarantee the culinary art effect, the accuracy is high and stability is good.
In one embodiment, according to the first detected temperature, performing temperature and humidity calibration on a humidity sensor disposed at a second position in the steaming oven in combination with an operation mode of the steaming oven to obtain a second detected temperature at the second position, specifically including:
Determining an operation mode of the steaming and baking oven, determining a calibration coefficient matched with the operation mode, and calculating to obtain a second detection temperature through the detection temperature of the temperature sensor and the calibration coefficient.
The calibration coefficient is determined according to deviation values of the temperature measuring point of the humidity sensor and the first detection temperature under different operation modes. The calibration factor is related to the distance between the humidity sensor and the temperature sensor. Specifically, the calibration coefficient is calculated by measuring the detected temperature of the humidity sensor and the detected temperature of the temperature sensor, respectively. The detected temperature of the humidity sensor, that is, the temperature of the temperature measuring point of the humidity sensor, can be obtained by measuring the temperature of the temperature measuring point of the humidity sensor by using a temperature measuring instrument. The detected temperature of the temperature sensor, that is, the first detected temperature, is detected by the temperature sensor.
It will be appreciated that there are a number of different modes of operation for the steam oven, such as a circular mode, a full air mode and a fire up and down mode. The user can select different operation modes according to different food types, so that the cooking effect is ensured. The humidity required by different food types is also different, for example, bread and biscuits need a low-humidity environment to make the surface crisp, and meat needs a high-humidity environment to ensure that the internal and external temperature fields of the food are small, so that the meat is heated uniformly.
When the steaming oven operates in the operation mode, the temperature uniformity in the steaming oven is also different, and the humidity sensor and the temperature sensor are arranged at different positions, so that the detected temperature at the temperature sensor is different from the detected temperature at the humidity sensor, namely, the first detected temperature and the second detected temperature are different. Therefore, according to the operation mode of the steaming and baking oven, the cooking effect required by a user is determined, and the calibration coefficient matched with the operation mode is determined, so that the second detection temperature, namely the detection temperature at the humidity sensor is conveniently determined, and whether the humidity detection value acquired by the humidity sensor is reliable and effective is judged.
In this embodiment, according to the operation mode of the steaming and baking oven, the calibration coefficient matched with the operation mode is determined, the accuracy of the humidity detection value of the humidity sensor is improved, the humidity in the steaming and baking oven can be accurately controlled in the subsequent cooking process, and the accuracy is high and the stability is good.
In one embodiment, the deviation value is characterized using a ratio of a temperature of the temperature measurement point of the humidity sensor to the first detected temperature.
The second detection temperature is obtained through calculation through the first detection temperature and the calibration coefficient, and the method specifically comprises the following steps:
the first detected temperature and the calibration coefficient are multiplied as a second detected temperature.
The deviation values corresponding to the respective modes have no fixed magnitude relation, and therefore the corresponding calibration coefficients have no fixed magnitude relation. The value range of the calibration coefficient corresponding to each mode is between 0 and 2. If the temperature of the temperature measuring point of the humidity sensor is larger than the first detection temperature, namely the temperature of the temperature measuring point of the temperature sensor, the calibration coefficient is larger than 1; otherwise, if the temperature of the temperature measuring point of the humidity sensor is smaller than the first detection temperature, the calibration coefficient is smaller than 1.
In this embodiment, the deviation between the temperature measurement point of the humidity sensor and the first detection temperature is represented by the calibration coefficient, and then a second detection temperature is calculated, and the second detection temperature is used as a basis for judging whether the humidity sensor is in a usable state, so that the accuracy of the humidity detection value is improved.
In one embodiment, the deviation value is characterized using a difference between the temperature of the temperature measurement point of the humidity sensor and the first detected temperature.
It will be appreciated that when the difference value is used to characterize the deviation value, the larger the deviation value, the greater the deviation of the temperature measurement point of the humidity sensor from the first detected temperature.
In this embodiment, the deviation value is represented by a difference value between the temperature of the temperature measuring point of the humidity sensor and the first detected temperature, so as to obtain a calibration coefficient and calculate the second detected temperature, so as to facilitate the subsequent determination of whether the humidity sensor is in a usable state.
In one embodiment, determining whether the humidity sensor disposed at the second location is in an available state based on the second detected temperature includes:
and recording abnormal times of the humidity sensor, recording normal times of the humidity sensor, and if the normal times exceed a normal threshold value, determining that the humidity sensor is in an available state.
Wherein the number of anomalies is determined based on the number of times the second detected temperature is less than the temperature threshold. The normal times are determined according to the times that the humidity detection value fluctuates within a preset period of time and does not exceed a preset value. The temperature threshold, the preset value and the normal threshold are determined according to experimental data analysis.
The humidity sensor used in this embodiment is a high temperature and humidity sensor. The working principle of the high temperature and humidity sensor is to detect the resistance difference of the two NTCs and determine the humidity detection value according to the corresponding relation between the resistance difference of the two NTCs and the humidity detection value. When the temperature is lower, the resistance value of the NTC is larger and the heating value is small, so that the resistance value difference of the two NTCs cannot be accurately converted into a humidity detection value, the detected humidity detection value is inaccurate, and the humidity detection value cannot be used as a basis for humidity control.
When the second detected temperature is greater than the temperature threshold, the humidity detection value of the humidity sensor is reliable and effective, and humidity control can be performed according to the humidity detection value; otherwise, when the second detected temperature is smaller than the temperature threshold, the humidity detection value of the humidity sensor is inaccurate invalid data, the humidity detection value cannot be used as a basis for humidity control, the occurrence of abnormality of the humidity sensor is judged, and the abnormal times of the humidity sensor are recorded.
When the fluctuation of the humidity detection value exceeds a preset value in a preset period, the humidity detection value of the humidity sensor is unstable, and the humidity in the steaming and baking oven cannot be represented; on the contrary, when the fluctuation of the temperature detection value in the preset period does not exceed the preset value, the humidity detection value of the humidity sensor is reliable and effective, the humidity in the steaming and baking oven can be accurately represented, the humidity sensor is judged to work normally, and the normal times of the humidity sensor are recorded.
When the normal times exceeds the normal threshold value, the humidity sensor is indicated to continuously work normally for a plurality of times, the humidity detection value is reliable and effective, the humidity in the steaming and baking oven can be accurately represented and can be used as the basis of humidity control, and therefore the humidity sensor is determined to be in a usable state.
In this embodiment, the second detected temperature is used as a basis for determining whether the humidity sensor is abnormal, and the fluctuation range of the humidity detection value is used as a basis for determining whether the humidity sensor works normally, so that the state of the humidity sensor can be known in time, the accuracy of subsequent humidity control is improved, and humidity control according to an inaccurate humidity detection value is avoided.
In one embodiment, the number of anomalies is determined based on the number of times the humidity detection value fluctuates beyond a preset value within a preset period of time.
It can be understood that when the humidity detection value fluctuates beyond the preset value within the preset period, the humidity detection value of the humidity sensor is unstable, and the humidity in the steaming and baking oven cannot be represented, so that the abnormality of the humidity sensor is judged, and the abnormal times of the humidity sensor are recorded.
In this embodiment, the humidity detection value is used as a basis for judging whether the humidity sensor is abnormal, so as to determine whether the humidity sensor is in a usable state, and improve the accuracy of humidity detection and humidity control.
In one embodiment, the number of anomalies is determined based on the number of times the second detected temperature is less than the temperature threshold and the number of times the humidity detection value fluctuates beyond a preset value within a preset period.
In this embodiment, the two parameters of the second detected temperature and the humidity detected value are used as the basis for judging whether the humidity sensor is abnormal, so that the accuracy of judging the abnormality of the humidity sensor is improved, and the subsequent humidity control according to the humidity sensor is facilitated.
In one embodiment, determining whether the humidity sensor disposed at the second location is in an available state based on the second detected temperature includes:
when the number of anomalies exceeds the anomaly threshold, it is determined that the humidity sensor is in an unavailable state. And when the humidity sensor is in the unavailable state and the last state is in the available state, determining that the humidity sensor is in a fault state.
It can be understood that when the number of anomalies exceeds the anomaly threshold, it is indicated that the humidity sensor continuously has anomalies for a plurality of times, and it is impossible to determine whether the humidity detection value is reliable and effective, and the humidity detection value cannot be used as a basis for humidity control, so that it is determined that the humidity sensor is in an unavailable state.
In the cooking process, when the humidity sensor is changed from the available state to the unavailable state, the humidity sensor is judged to have a fault, the humidity sensor is determined to be in the fault state, and the control is not performed according to the humidity detection value of the humidity sensor until the next cooking is judged to be in the available state.
In this embodiment, whether the humidity sensor is in an unavailable state is determined according to the abnormal times, and then a fault state is determined according to the state change of the humidity sensor, so that the judgment on the state of the humidity sensor is realized, humidity control according to an inaccurate humidity detection value is avoided, and the accuracy of humidity control is improved.
In one embodiment, the humidity sensor is determined to be in an unavailable state when the humidity detection value is not within a preset range.
The preset range is obtained through fitting experimental data.
The preset range is the humidity detection value of the steaming oven in the normal working state. If the humidity detection value exceeds the preset range, the humidity detection value is determined to be inaccurate, and the humidity sensor is determined to be in an unavailable state.
In this embodiment, whether the humidity sensor is in an unavailable state is determined according to the humidity detection value, so that humidity control according to the inaccurate humidity sensor is avoided, the state of the humidity sensor is determined in time, and the cooking effect is ensured.
In one embodiment, the humidity sensor is determined to be in an unavailable state when the number of anomalies exceeds an anomaly threshold value and the humidity detection value is not within a preset range.
In this embodiment, two parameters, namely the abnormal times and the humidity detection value, are used as the basis for judging that the humidity sensor is in an unavailable state, so that the accuracy of state judgment of the humidity sensor is improved, and the accuracy of humidity control is ensured.
In one embodiment, the humidity in the steaming oven is controlled according to the humidity detection value of the humidity sensor, and specifically comprises:
and acquiring a humidity setting value. And performing PID control on the humidity control element of the steaming and baking oven according to the humidity detection value and the humidity setting value.
Wherein the humidity setting value is the humidity required by the food. If the deviation between the humidity detection value and the humidity setting value is large, the cooking effect of the food is affected, and therefore PID control is required to be performed according to the humidity detection value and the humidity setting value, so that the deviation between the humidity detection value and the humidity setting value is reduced, and finally, the humidity detection value and the humidity setting value are equal.
The PID control is to acquire the deviation between the humidity set value and the humidity detection value, namely the deviation between the target humidity and the current humidity by adopting a PID control algorithm, and control the humidity control element according to the deviation, so as to realize the purpose that the humidity set value is equal to the humidity detection value.
Specifically, the deviation range may be determined according to actual needs. The temporary deviation range is 1-10, and if the deviation obtained according to the PID control algorithm is equal to 5, the humidity detection value is close to the humidity setting value; if the obtained deviation is greater than 5, the humidity detection value is smaller than the humidity setting value, and the greater the deviation is, the greater the difference between the humidity detection value and the humidity setting value is, and the water inlet of the humidity control element needs to be controlled. If the obtained deviation value is smaller than 5, the deviation value is larger than the humidity setting value, and the smaller the deviation is, the larger the difference value between the humidity detection value and the humidity setting value is, and the humidity control element exhaust needs to be controlled.
In this embodiment, according to humidity setting value and humidity detection value control humidity control element, adjust the humidity in the steaming oven for humidity detection value equals with humidity setting value, guarantees that the humidity in the steaming oven satisfies the required humidity of food culinary art in-process, thereby guarantees the culinary art effect of food, promotes user's use experience.
In one embodiment, the humidity control element comprises: a heating plate.
And performing PID control on the humidity control element of the steaming and baking oven according to the humidity detection value and the humidity setting value, wherein the PID control comprises the following steps: and controlling the power of the heating disc according to the PID.
It will be appreciated that humidity is a physical quantity that represents the degree of dryness of air, the water vapor content of which can be indicative of the degree of dryness of air. The higher the power of the heating disc is, the faster the speed of converting water into water vapor is, and the water is conveniently discharged through the air valve, so that the humidity in the air is increased, and the increase of a humidity detection value is realized; on the contrary, the smaller the power of the heating plate is, the slower the speed of converting water into water vapor is, so that the humidity in the air is reduced, and the reduction of the humidity detection value is realized.
In this embodiment, the power of the heating plate is controlled by the PID to increase or decrease the humidity in the air, so that the humidity detection value approaches the humidity setting value, thereby ensuring that the humidity in the steaming oven meets the humidity required by food cooking.
In one embodiment, the humidity control element comprises: and an air valve.
And performing PID control on the humidity control element of the steaming and baking oven according to the humidity detection value and the humidity setting value, wherein the PID control comprises the following steps: and controlling the opening time of the air valve according to the PID.
Specifically, the later the air valve is opened, the slower the speed of discharging the water vapor in the air is, so that the humidity detection value is slowly reduced; on the contrary, the earlier the air valve opening time is, the faster the water vapor in the air is discharged, so that the humidity detection value is reduced rapidly.
In this embodiment, the opening time of the air valve is controlled according to PID, so as to change the falling rate of the humidity detection value, and satisfy the humidity required by the food cooking process, thereby ensuring the cooking effect.
In one embodiment, the PID control of the humidity control element of the steaming oven according to the humidity detection value and the humidity setting value comprises: and controlling the opening size of the air valve according to the PID.
Specifically, the larger the air valve is opened, the faster the water vapor in the air is discharged, so that the humidity detection value is reduced rapidly; conversely, the smaller the air valve is opened, the slower the speed of discharging the water vapor in the air is, thereby realizing slow reduction of the humidity detection value.
In this embodiment, the falling rate of the humidity detection value is changed according to the opening of the PID control air valve, so as to satisfy the humidity required by the food cooking process, thereby ensuring the cooking effect.
In one embodiment, the humidity control element comprises: a water tank.
And performing PID control on the humidity control element of the steaming and baking oven according to the humidity detection value and the humidity setting value, wherein the PID control comprises the following steps: and controlling the water inlet time of the water tank according to the PID.
Specifically, the later the water inlet time of the water tank is, the slower the speed of generating water vapor in the air is, so that the humidity detection value is slowly increased; on the contrary, the earlier the water inlet time of the water tank is, the faster the speed of generating water vapor in the air is, thereby realizing the rapid increase of the humidity detection value.
In this embodiment, by controlling the water inlet time of the water tank, the speed of generating water vapor in the air is changed, so as to change the humidity detection value, and the humidity detection value gradually approaches the humidity setting value, so as to satisfy the humidity required in the food cooking process.
In one embodiment, the PID control of the humidity control element of the steaming oven according to the humidity detection value and the humidity setting value comprises: and controlling the water inlet size of the water tank according to the PID.
Specifically, the larger the water inlet size of the water tank is, the larger the water content in the steaming oven is, and the faster the speed of generating water vapor in the air is, so that the humidity detection value is rapidly increased; on the contrary, the smaller the water inlet size of the water tank is, the smaller the water content in the steaming oven is, and the slower the speed of generating water vapor in the air is, so that the humidity detection value is reduced rapidly.

In one embodiment, obtaining the humidity setting includes:
and obtaining the food type, determining the food load according to the change rate of the humidity curve matched with the food type, and determining the humidity setting value according to the relation between the food load and the humidity setting value.
Wherein, through fitting experimental data, the food load amount is positively correlated with the change rate of the humidity curve. After the food type is determined, the food load of the same food type is different, and the change rate of the humidity curve is different. Specifically, the greater the food load, the faster the rate of change of the humidity profile; conversely, the smaller the food load, the slower the rate of change of the humidity profile.
And obtaining the corresponding relation between the food load and the change rate of the humidity curve according to a large amount of experimental data, so as to determine the food load according to the change rate of the humidity curve. After the food type and the food load are determined, the humidity required for the food is different in different time periods, and thus the humidity setting is different. For example, meat requires a higher humidity during the first half of cooking, ensuring that the internal and external temperature fields of the food are small and heated uniformly, and requires a lower humidity during the second half of cooking, making the food crisp and tender.
Humidity settings for different kinds of foods were fitted according to experimental data.

The higher the humidity setting gear is, the higher the power of the heating disc is, and the longer the water inlet time is; on the contrary, the smaller the humidity setting gear is, the smaller the heating disc power is, and the shorter the water inlet time is.
When the cooked time is greater than the cooking time threshold, controlling the water inlet interval to be the product of the humidity setting gear and the first interval value; otherwise, when the cooked time is smaller than or equal to the cooking time threshold, controlling the water inlet interval to be the product of the humidity setting gear and the second interval value. The first interval value, the second interval value, and the cooking time threshold value may be selected according to actual situations, and are not particularly limited herein.
