Based on the baking equipment shown in fig. 1 or fig. 2, as shown in fig. 3, the present application further provides a control method of the baking equipment, which specifically includes the following steps:
s101, the control device acquires a first temperature value detected by the first temperature sensor and a second temperature value detected by the second temperature sensor.
The first temperature sensor and the second temperature sensor can be any two different temperature sensors arranged on the baking equipment.
For example, the first temperature sensor and the second temperature sensor may be any two of the top temperature sensor 41, the left temperature sensor 42, the right temperature sensor 43, and the bottom temperature sensor 44 shown in fig. 2.
S102, when the first temperature value is smaller than the second temperature value and the difference value between the second temperature value and the first temperature value is larger than a first preset threshold value, the control device adjusts the heating power of at least one heating device in the plurality of heating devices, so that the difference value between the second temperature value and the first temperature value is smaller than or equal to the first preset threshold value.
If the difference value between the second temperature value and the first temperature value is greater than a first preset threshold value, it indicates that the heating temperature difference of different positions inside the box body of the baking equipment is large, so that food inside the box body is heated unevenly. At this time, the control device can adjust the heating power of at least one heating device in the plurality of heating devices to accurately control the heating temperature inside the box body, so that the difference between the second temperature value and the first temperature value is smaller than or equal to a first preset threshold value.
The first preset threshold may be a preset reasonable temperature value, for example, 1 ℃.
Optionally, the first temperature sensor and the second temperature sensor may have the following three possible situations according to different arrangement positions of the temperature sensors:
the first temperature sensor is arranged on the top wall in the box body, and the second temperature sensor is arranged on the side wall or the bottom wall in the box body.
Wherein, the first temperature value is the roof temperature value of the inside of box, and the second temperature value can be the left side wall temperature value, the right side wall temperature value or the bottom wall temperature value of the inside of box.
Based on the case one, the step S102 may be specifically implemented as: and when the first temperature value is smaller than the second temperature value and the difference value between the second temperature value and the first temperature value is larger than a first preset threshold value, controlling the top heating device to increase the heating power so that the difference value between the second temperature value and the first temperature value is smaller than or equal to the first preset threshold value.
For example, if the baking process currently performed by the baking apparatus 100 is 170 ℃, the heating is performed for 40 minutes up and down. At this time, the bottom heating means 23 and the top heating means 21 of the toasting device 200 are heated simultaneously. If the first predetermined threshold is 1 ℃. In the case where the temperature value detected by the bottom temperature sensor 44 is 165 deg.c and the temperature value detected by the top temperature sensor 41 is 163 deg.c, the control device may increase the heating power of the top heating device since the absolute value of the difference between the two temperature values is 2 deg.c, which is greater than the first preset threshold value of 1 deg.c, and the temperature of the bottom wall of the cabinet 1 is greater than the temperature of the top wall.
And in case II, the first temperature sensor is arranged on the side wall in the box body, and the second temperature sensor is arranged on the top wall or the bottom wall in the box body.
The first temperature value can be a left side wall temperature value or a right side wall temperature value inside the box body. The second temperature value may be a top wall temperature value or a bottom wall temperature value of the interior of the tank.
Based on case two, step S102 may be implemented as: and when the first temperature value is smaller than the second temperature value and the difference value between the second temperature value and the first temperature value is larger than a first preset threshold value, controlling the back heating device to increase the heating power so that the difference value between the second temperature value and the first temperature value is smaller than or equal to the first preset threshold value.
And in the third situation, the first temperature sensor is arranged on the bottom wall in the box body, and the second temperature sensor is arranged on the top wall or the side wall in the box body.
Wherein, the first temperature value is the bottom wall temperature value in the box. The second temperature value may be a top wall temperature value or a left side wall temperature value or a right side wall temperature value of the inside of the case.
Based on case three, step S102 may be specifically implemented as: and when the first temperature value is smaller than the second temperature value and the difference value between the second temperature value and the first temperature value is larger than a first preset threshold value, controlling the bottom heating device to increase the heating power so that the difference value between the second temperature value and the first temperature value is smaller than or equal to the first preset threshold value.
For example, if the baking process currently performed by the baking apparatus 100 is 170 ℃, the up-down heating + the back heating is performed for 40 minutes. At this time, the top heating device 21, the back heating pipe 22, and the bottom heating device 23 of the toasting apparatus 200 are heated simultaneously. If the first preset threshold is set to 1 ℃. In the case that the temperature value detected by the top temperature sensor 44 is 165 ℃, the temperature value detected by the left side temperature sensor 42 is 163 ℃, and the temperature value detected by the bottom temperature sensor 44 is 164 ℃, the absolute value of the difference between the temperature value detected by the top temperature sensor 44 and the temperature value detected by the left side temperature sensor 42 is 2 ℃ and is greater than the first preset threshold value 1 ℃, then the control device may increase the heating power of the back heating device at this time.
Based on the control method of the baking equipment shown in fig. 3, a plurality of temperature sensors are arranged in the box body of the baking equipment, and the temperature sensors can be distributed at different positions in the box body so as to detect the temperature in the box body of the baking equipment in multiple directions. During the process of baking the food by using the baking device, the control device of the baking device can acquire the temperature values detected by the plurality of temperature sensors. If the difference between the acquired temperature values detected by any two different temperature sensors is greater than a first preset threshold, the control device can accurately adjust the heating power of at least one heating device in the plurality of heating devices according to the setting position of the temperature sensor, so that the difference between the acquired temperature values detected by any two different temperature sensors is smaller than or equal to the first preset threshold. Therefore, in the process of baking food by using the baking equipment, the temperature difference value between the heating temperatures at different positions in the box body can be kept within a preset range, so that the food in the box body is heated uniformly. Can promote this toast equipment's the effect of toasting like this, satisfy user's culinary art demand.
Optionally, as shown in fig. 4, an embodiment of the present application further provides a control method of a baking apparatus, where the method includes the following steps:
s201, the control device acquires a first temperature value detected by the first temperature sensor and a second temperature value detected by the second temperature sensor.
The first temperature sensor and the second temperature sensor may refer to the description related to the embodiment shown in fig. 3, and are not described herein again.
S202, when the difference value between the first temperature value and the second temperature value is larger than a second preset threshold value, adjusting the rotating speed of the fan to enable the difference value between the first temperature value and the second temperature value to be smaller than or equal to the second preset threshold value.
Optionally, the second preset threshold is smaller than the first preset threshold, for example, if the first preset threshold is 1 ℃, the second preset threshold may be 0.5 ℃.
Based on the embodiment shown in fig. 4, the blower of the baking device is used to rapidly disperse the heat inside the box body, so as to be uniformly distributed inside the box body of the baking device. If the heating temperature difference inside the box body of the baking equipment is large, the rotating speed of the back fan can be increased so that the heat inside the box body can be rapidly dispersed, and then the inside of the box body is heated uniformly.
Optionally, as shown in fig. 5, an embodiment of the present application further provides a control method of a baking apparatus, where the method includes the following steps:
s301, the control device obtains image information of food in the box body.
Wherein, the inside shooting device that is provided with of box of toasting equipment, this shooting device is used for gathering the image information of the inside food of box.
When the baking equipment is about to finish the current baking program, the shooting device collects the image information of the food and sends the collected image information to the control device, and the control device receives the image information sent by the shooting device.
Optionally, when the current baking program is to be completed, the baking device may specifically be configured to execute the current baking program for 80% of the preset time. For example, if the baking procedure is 170 ℃ and the oven is heated up and down for 40 minutes, the baking device starts to execute the step S103 when the oven is heated up and down for 32 minutes, and the control device acquires the image information of the food in the box.
S302, the control device determines the coloring completion degree of the food according to the image information of the food.
In a possible implementation manner, after the control device receives the image information of the food sent by the shooting device, the control device determines the coloring information of the top of the food of the received image information. And comparing the coloring information of the top of the received food with the preset food coloring information to determine the coloring completion degree of the food inside the box body, wherein the coloring completion degree of the food is used for representing the coloring progress of the top of the current food.
In some embodiments, coloring information on the top of the food is extracted from the image information of the food, which is essentially a representation of pixels, which can be represented in a digital form. Therefore, the coloring information of the top of the food of the received image information and the preset food coloring information can both adopt a digital representation form, so when the coloring information of the top of the food of the received image information is compared with the preset food coloring information, the final comparison is the magnitude of the numerical value, and the coloring completion degree of the food inside the box body is determined according to the comparison result.
Optionally, the control device determines the coloring completion degree of the food inside the box body by any one of the following implementation manners:
in the first implementation, the coloring completion degree may be expressed in a numerical value in the form of a percentage, for example, the coloring completion degree may be 100%, 80%, 50%.
In some embodiments, the coloring completeness may also be a value greater than 100%. The coloring completion degree is more than 100%, which can indicate that the food inside the box body is in an excessively colored state, and the surface of the food can be scorched or cracked.
In the second implementation manner, the coloring completion degree is expressed in a form of a grade. For example, the coloring completeness may be divided into four levels, a first level indicating that the top of the food is not colored yet, a second level indicating that the top of the food is lightly colored, a third level indicating that the top of the food is medium colored, and a fourth level indicating that the top of the food is completely colored.
S303, the control device adjusts the heating power of the top heating device according to the coloring completion degree of the food.
In some embodiments, if the coloring completion degree of the food is greater than or equal to a third preset threshold, the control device controls the top heating device to stop heating.
The third preset threshold may be set by a user, configured in the intelligent recipe, or pre-configured by the baking device.
For example, in the case where the upper color completion degree may be expressed as a numerical value in percentage, the third preset threshold may be 100%. Alternatively, in the case where the upper color completion degree is expressed in the form of a level, the third preset threshold may be a fourth level.
It should be understood that, in the case that the coloring completion degree is greater than or equal to the third preset threshold, it indicates that the coloring on the top of the food has been satisfied, and therefore the control device controls the top heating device to stop heating, so as to avoid overbaking the top of the food.
In some embodiments, if the coloring completion degree of the food is less than the third preset threshold and greater than or equal to the fourth preset threshold, the control device controls the top heating device to maintain the current heating power.
The fourth preset threshold may be set by a user, configured in an intelligent recipe, or pre-configured by the baking device.
For example, in the case where the upper color completion degree may be expressed as a numerical value in percentage, the fourth preset threshold may be 80%. Alternatively, in the case where the upper color completion degree is expressed in the form of a level, the fourth preset threshold may be a third level.
It should be understood that the coloring completion degree is less than the third preset threshold and greater than or equal to the fourth preset threshold, which indicates that the coloring condition of the food at this time matches the execution state of the current baking program, the baking device continues to keep the current heating power to continue heating, and the top of the food can be baked and colored to reach the optimal coloring state when the baking program is executed and completed.
In some embodiments, if the coloring completion degree of the food is less than a fourth preset threshold, the control means controls the top heating means to increase the heating power.
When the coloring completion degree of the food is smaller than the fourth preset threshold value, the coloring progress of the food in the box body is lower, if the current heating power is kept to continue heating, the top of the food in the box body is possibly not colored completely when the baking time in the baking procedure is reached. Therefore, if the coloring completion degree of the food is less than the fourth preset threshold, the control device controls the top heating device to increase the heating power so as to accelerate the coloring speed of the food.
Based on the embodiment shown in fig. 5, the baking device can determine the coloring condition of the food according to the coloring completion degree of the food, and then adjust the heating power of the top heating device, so as to avoid the top of the food from being coked due to too high baking temperature or being insufficiently colored due to too low baking temperature. Thus, the food in the box body can reach the optimal coloring state.
Optionally, as shown in fig. 6, a method for controlling a toasting apparatus according to an embodiment of the present application includes the following steps:
s401, the control device obtains image information of food in the box body.
S402, the control device determines whether the shape of the baked food meets a preset condition according to the image information of the food.
As a possible implementation, the control means determines the baked shape of the food based on the image information of the food. The control device determines the similarity between the shape of the baked food and a preset shape. In the case where the similarity is greater than the threshold, the control device determines that the shape of the baked food satisfies a preset condition. Alternatively, in a case where the similarity is less than or equal to the threshold, the control device determines that the shape of the food after baking does not satisfy the preset condition.
Illustratively, the predetermined shape may be a crack on top of a food item (e.g., cake, cookie, etc.).
And S403, if the shape of the baked food meets the preset condition, controlling the top heating device to stop heating by the control device.
Based on the embodiment shown in fig. 6, the control device can also analyze the shape of the baked food according to the image information of the food in the box body, and when the shape of the baked food reaches the preset condition, the top heating device is controlled to stop heating in time, so that the situation that the food is excessively baked and the taste is not good enough can be avoided.
