[0002] With the rapid development of integrated stoves, the intelligence of integrated stoves has become the focus of people's attention. At present, integrated stoves usually set temperature thresholds to determine the speed of the cooling fan.

This heat dissipation method has the defects of poor heat dissipation effect, inability to make early judgments on heat dissipation, and hysteresis, which leads to poor heating rate of the steam oven and poor user experience.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0034] It should be noted that the terms "first", "second", "target", and "original" in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0035] Figure 1 This is a schematic diagram of the first process of a method for controlling a heat dissipation fan provided in an embodiment of the present application. This embodiment can be applied to the case where the temperature inside the steam oven and the heat dissipation temperature of the area where the heat dissipation fan is located are linked to jointly control the speed of the heat dissipation fan. The method for controlling a heat dissipation fan provided in this embodiment can be executed by a control device for a heat dissipation fan provided in an embodiment of the present application. The device can be implemented in software and / or hardware and integrated in an electronic device that executes the method. Preferably, the electronic device in the embodiment of the present application can be an integrated stove, and the execution subject that executes the method is a microcontroller in the integrated stove.

[0036] See also Figure 1 The method of this embodiment includes but is not limited to the following steps:

[0037] S110. In the current task cycle, the current temperature inside the steam oven is obtained through the first temperature sensor, and the current heat dissipation temperature of the heat dissipation fan is obtained through the second temperature sensor.

[0038] Among them, the integrated stove is equipped with a heat dissipation fan, a first temperature sensor and a second temperature sensor; this embodiment does not limit the installation position of the heat dissipation fan, and it can be optionally configured at the top of the steam oven; the first temperature sensor is configured in the box of the steam oven in the integrated stove, but the specific installation position of the first temperature sensor in the box is not limited, and the first temperature sensor is used to detect the temperature inside the box of the steam oven in the integrated stove; the second temperature sensor is configured at a preset position of the heat dissipation fan in the integrated stove, but the specific installation position of the second temperature sensor on the heat dissipation fan is not limited, and the second temperature sensor is used to detect the heat dissipation temperature of the area where the heat dissipation fan in the integrated stove is located.

[0039] In the embodiment of the present application, during the operation of the steam oven, the microcontroller divides the operation time of the steam oven into multiple task cycles, and the time interval of each task cycle is a fixed time, such as 5 seconds; in each task cycle, the microcontroller obtains the temperature inside the steam oven in real time through the first temperature sensor, and obtains the heat dissipation temperature of the area where the heat dissipation fan is located in real time through the second temperature sensor. For example: in the current task cycle, the current temperature inside the steam oven is obtained through the first temperature sensor, and the current heat dissipation temperature of the heat dissipation fan is obtained through the second temperature sensor.

[0040] S120, determining a current speed value of the cooling fan in the current task cycle according to the current temperature inside the box and the current cooling temperature.

[0041] In an embodiment of the present application, after the microcontroller obtains the current temperature inside the steam oven and the current heat dissipation temperature of the area where the heat dissipation fan is located during the current task cycle, it then links the current temperature inside the oven and the current heat dissipation temperature to jointly control the speed of the heat dissipation fan.

[0042] Specifically, the current speed value of the heat dissipation fan in the current task cycle is determined according to the current temperature in the box and the current heat dissipation temperature, including: determining whether the current temperature in the box reaches the first temperature value or whether the current heat dissipation temperature reaches the second temperature value; if the current temperature in the box reaches the first temperature value or the current heat dissipation temperature reaches the second temperature value, it indicates that the temperature in the box of the steam oven is about to reach, has reached or exceeds the target temperature value set by the user for the steam oven, and the temperature between the stove glass and the steam oven is very high, so that the user cannot operate it. At this time, the microcontroller should determine the current speed value of the heat dissipation fan as the maximum speed value, so as to complete the heat dissipation task of the steam oven in a short time; if the current temperature in the box does not reach the first temperature value and the current heat dissipation temperature does not reach the second temperature value, it indicates that the temperature in the box of the steam oven has not reached the target temperature value set by the user for the steam oven, and it is necessary to finely control the speed of the heat dissipation fan according to the current specific temperature conditions. At this time, the microcontroller should: determine the heat dissipation temperature difference between the current heat dissipation temperature and the previous heat dissipation temperature detected in the previous task cycle, and determine the current speed value based on the current temperature in the box, the current heat dissipation temperature and the heat dissipation temperature difference.

[0043] Among them, there may be a size relationship between the first temperature value and the second temperature value, such as the first temperature value is greater than the target temperature value set by the user for the steam oven, and the second temperature value is greater than the first temperature value; there may also be no size relationship between the first temperature value and the second temperature value, and the specific numerical values ​​of the first temperature value and the second temperature value can be arbitrarily set by the user according to actual needs, or can be the default values ​​pre-set when the integrated stove is debugged at the factory.

[0044] Furthermore, there may be multiple specific implementation processes for determining the current rotation speed value based on the current temperature inside the box, the current heat dissipation temperature and the heat dissipation temperature difference. This application explains the following two implementation methods.

[0045] One implementation method is: a fan speed adjustment function may be pre-set and stored in a storage unit of a microcontroller; after the microcontroller obtains the current temperature inside the box, the current heat dissipation temperature and the heat dissipation temperature difference, the fan speed adjustment function is called from the storage unit, and the current temperature inside the box and the heat dissipation temperature difference are first substituted into the fan speed adjustment function for calculation, so as to obtain a first adjustment value for adjusting the speed of the heat dissipation fan in the current task cycle; and then numerical calculations are performed on the current heat dissipation temperature and the first adjustment value to obtain the current speed value.

[0046] Among them, the independent variables in the fan speed adjustment function include at least the current temperature in the box and the heat dissipation temperature difference value, and may also include the target temperature value, and the dependent variable in the fan speed adjustment function is the first adjustment value of the heat dissipation fan speed. The fan speed adjustment function represents the functional relationship between the first adjustment value of the heat dissipation fan speed and the current temperature in the box, the heat dissipation temperature difference value and the target temperature value. The first adjustment value can be a positive number, a negative number or zero. When the first adjustment value is a positive number, it indicates that the speed of the heat dissipation fan needs to be increased in the current task cycle, when the first adjustment value is a negative number, it indicates that the speed of the heat dissipation fan needs to be reduced in the current task cycle, and when the first adjustment value is zero, it indicates that the speed of the heat dissipation fan does not need to be changed in the current task cycle.

[0047] Another implementation method is: the temperature inside the steam oven can be pre-divided into multiple temperature intervals from the lowest temperature to the highest temperature, and the heat dissipation temperature difference between two adjacent task cycles in the area where the heat dissipation fan is located can be divided into multiple temperature intervals from the lowest temperature to the highest temperature. This embodiment does not limit the specific number of temperature intervals, and a corresponding fan speed adjustment table is formulated based on these two temperature intervals, and the fan speed adjustment table is stored in a storage unit of a microcontroller; after the microcontroller obtains the current temperature inside the box, the current heat dissipation temperature and the heat dissipation temperature difference, the fan speed adjustment table is called from the storage unit, and the first temperature interval in which the current temperature inside the box is located and the second temperature interval in which the heat dissipation temperature difference is located are first determined, and the first temperature interval and the second temperature interval are searched from the fan speed adjustment table based on the first temperature interval and the second temperature interval, and a first adjustment value for adjusting the speed of the heat dissipation fan in the current task cycle can be obtained; and then the current heat dissipation temperature and the first adjustment value are numerically calculated to obtain the current speed value.

[0048] For example, the temperature inside the steam oven (represented as T) is pre-divided into four temperature intervals from the lowest temperature to the highest temperature, such as T≤75%*T 目标 、75%*T 目标 <T≤90%*T 目标 、90%*T 目标 <T≤T 目标 and T>T 目标 , the heat dissipation temperature difference (recorded as △T1) is pre-divided into four temperature intervals from the lowest temperature to the highest temperature, such as △T1≤0, △T1≤a, a<△T1≤b and △T1>b; then the fan speed adjustment table is shown in Table 1 below:

[0049] Table 1 Fan speed adjustment table

[0050]

[0051] The fan speed settings in Table 1 may be fixed numbers l, m and n, where the magnitude relationship may be l>m>n; 75% and 90% are examples, and this embodiment does not limit the specific values ​​and may be set according to actual use requirements; T 目标 Indicates the target temperature value set by the user for the steam oven; a and b are constant and positive numbers. Under normal circumstances, the heating temperature is between a and b. The thresholds of a, b and interval values ​​corresponding to different modes of the integrated stove will also be different. It can be understood that when T ≥ a certain value (such as 250°C), the cooling fan runs at a constant maximum speed and no longer slows down. Optionally, this embodiment does not limit the way to change the speed, and the low temperature of the cooling zone can also be increased to reduce the speed.

[0052] S130, controlling the heat dissipation fan to operate based on the current speed value, so that the temperature inside the steam oven reaches the target temperature value within a preset time.

[0053] In an embodiment of the present application, within the current task cycle, the microcontroller determines the current speed value of the cooling fan, and then controls the cooling fan to operate based on the current speed value; in the same way, within each task cycle, the speed of the cooling fan is precisely adjusted based on the current temperature inside the steam oven and the current cooling temperature of the area where the cooling fan is located.

[0054] The technical solution provided by this embodiment is that in the current task cycle, the current box temperature of the steam oven is obtained through the first temperature sensor, and the current heat dissipation temperature of the heat dissipation fan is obtained through the second temperature sensor; the current speed value of the heat dissipation fan in the current task cycle is determined according to the current box temperature and the current heat dissipation temperature; the heat dissipation fan is controlled to operate based on the current speed value, so that the box temperature of the steam oven reaches the target temperature value at the preset time. The application configures a second temperature sensor in the integrated stove, which is used to detect the heat dissipation temperature of the area where the heat dissipation fan is located in the integrated stove, and can sense the temperature of the heat dissipation area in real time; combined with the box temperature of the steam oven obtained by the first temperature sensor and the heat dissipation temperature difference value in two adjacent task cycles, the speed of the heat dissipation fan is adjusted accurately and in advance, which can solve the defect of the prior art that the speed of the range hood is adjusted only when the box temperature reaches the set temperature threshold, which causes the failure to make a judgment on the heat dissipation in advance and has a hysteresis. When the box temperature is low, no heat is wasted, and the heating rate of the integrated stove can be improved. When the box temperature rises or the temperature rises too fast, the heat dissipation efficiency of the integrated stove can be improved, and the user's experience of using the integrated stove can be improved.

[0055] The following further describes the control method of the heat dissipation fan provided by the embodiment of the present application. Figure 2 A second flow chart of a control method for a heat dissipation fan provided in an embodiment of the present application. The embodiment of the present application is optimized on the basis of the above embodiments, and the specific optimization is as follows: the present embodiment explains in detail the process of controlling the rotation speed of the range hood. Among them, the integrated stove is also equipped with a range hood. The present embodiment does not limit the installation position of the range hood, and the optional range hood can be arranged at the rear end of the steam oven.

[0056] See also Figure 2 The method of this embodiment includes but is not limited to the following steps:

[0057] S210: When it is detected that the steam oven starts to start, the range hood is controlled to run at the lowest speed.

[0058] In an embodiment of the present application, the microcontroller detects the on-off status of the steam oven in real time. When it is detected that the user has started the steaming and baking function of the steam oven, the range hood is controlled to run at the lowest speed so that the smoke generated by the steam oven can be discharged in time.

[0059] S220: During the heating process of the steam oven, determine the temperature difference between the current temperature inside the oven and the previous temperature inside the oven detected in the previous task cycle.

[0060] In an embodiment of the present application, a first temperature sensor is arranged in the box of the steam oven in the integrated stove, and the first temperature sensor is used to detect the temperature inside the box of the steam oven in the integrated stove, and the microcontroller obtains the temperature inside the box of the steam oven through the first temperature sensor in real time; in the current task cycle, after the microcontroller obtains the current box temperature of the steam oven, it calculates the box temperature difference between the current box temperature and the previous box temperature detected in the previous task cycle.

[0061] S230: Determine a second adjustment value for adjusting the rotation speed of the range hood according to the current temperature in the cabinet and the temperature difference in the cabinet.

[0062] One implementation method is: the range hood speed adjustment function may be pre-set and stored in a storage unit of a microcontroller; after the microcontroller obtains the current temperature inside the box and the temperature difference inside the box, the range hood speed adjustment function is called from the storage unit, and the current temperature inside the box and the temperature difference inside the box are first substituted into the range hood speed adjustment function for calculation, so as to obtain a second adjustment value for adjusting the speed of the range hood within the current task cycle.

[0063] Among them, the independent variables in the range hood speed adjustment function include at least the current temperature in the box and the temperature difference in the box, and may also include the target temperature value. The dependent variable in the range hood speed adjustment function is the second adjustment value of the range hood speed. The range hood speed adjustment function represents the functional relationship between the second adjustment value of the range hood speed and the current temperature in the box, the temperature difference in the box and the target temperature value. The second adjustment value can be a positive number, a negative number or zero. When the second adjustment value is a positive number, it indicates that the speed of the range hood needs to be increased in the current task cycle. When the first adjustment value is a negative number, it indicates that the speed of the range hood needs to be reduced in the current task cycle. When the first adjustment value is zero, it indicates that the speed of the range hood does not need to be changed in the current task cycle.

[0064] Another implementation method is: the temperature inside the steam oven can be pre-divided into multiple temperature intervals from the lowest temperature to the highest temperature, and the temperature difference value inside the oven between two adjacent task cycles can be divided into multiple temperature intervals from the lowest temperature to the highest temperature. This embodiment does not limit the specific number of temperature intervals, and a corresponding range hood speed adjustment table is formulated based on these two temperature intervals, and the range hood speed adjustment table is stored in the storage unit of the microcontroller; after the microcontroller obtains the current temperature inside the oven and the temperature difference value inside the oven, the range hood speed adjustment table is called from the storage unit, and the first temperature interval in which the current temperature inside the oven is located and the third temperature interval in which the temperature difference value inside the oven is located are first determined, and based on the first temperature interval and the third temperature interval, the range hood speed adjustment table is searched to obtain a second adjustment value for adjusting the speed of the range hood within the current task cycle.

[0065] For example, the temperature inside the steam oven (represented as T) is pre-divided into four temperature intervals from the lowest temperature to the highest temperature, such as T≤75%*T 目标 、75%*T 目标 <T≤90%*T 目标 、90%*T 目标 <T≤T 目标 and T>T 目标 , pre-dividing the temperature difference in the box (recorded as △T2) from the lowest temperature to the highest temperature into four temperature intervals, such as △T2≤0, △T2≤c, c<△T2≤d and △T2>d; then the range hood speed adjustment table is shown in Table 2 below:

[0066] Table 2 Range hood speed adjustment table

[0067]

[0068]

[0069] The range hood speed settings in Table 2 may be fixed numbers x, y and z, where the magnitude relationship may be x>y>z; 75% and 90% are examples, and this embodiment does not limit specific values ​​and may be set according to actual use requirements; T 目标 Indicates the target temperature value set by the user for the steam oven; c and d are constant and positive numbers. Under normal circumstances, the heating temperature is between c and d. The thresholds of c, d and interval values ​​corresponding to different modes of the integrated stove will also be different.

[0070] S240, performing numerical calculation on the current temperature inside the box and the second adjustment value to obtain the current rotation speed value.

[0071] In an embodiment of the present application, after the microcontroller determines the second adjustment value for adjusting the speed of the range hood based on the current temperature inside the box and the temperature difference inside the box, the current temperature inside the box and the second adjustment value are added to obtain the current speed value of the range hood in the current task cycle.

[0072] The technical solution provided in this embodiment controls the range hood to run at the lowest speed when it is detected that the steam oven starts to start; during the heating process of the steam oven, determines the temperature difference between the current temperature inside the oven and the previous temperature inside the oven detected in the previous task cycle; determines a second adjustment value for adjusting the speed of the range hood based on the current temperature inside the oven and the temperature difference inside the oven; and performs numerical calculations on the current temperature inside the oven and the second adjustment value to obtain the current speed value. The present application configures a first temperature sensor in the integrated stove to detect the temperature inside the steam oven in the integrated stove, and then calculates the temperature difference inside the steam oven between two adjacent task cycles. The temperature change of the steam oven can be sensed in real time, and then the speed of the range hood can be accurately pre-adjusted in advance according to the temperature inside the oven and the temperature difference inside the oven. This can solve the defect of the prior art that the speed of the range hood is not adjusted until the temperature inside the oven reaches the set temperature threshold, resulting in the inability to make advance judgments on the heat dissipation and the existence of a lag. The present application controls the range hood and the heat dissipation fan separately, which not only ensures that heat is not wasted when the temperature inside the oven is low, and the heating rate of the integrated stove can be improved, but also ensures that when the temperature inside the oven rises or rises too quickly, the heat dissipation efficiency of the integrated stove can be improved, thereby improving the user experience of using the integrated stove.
