Fig. 1 is a flowchart illustrating a method for controlling a cooking appliance according to an embodiment of the present invention, and as shown in fig. 1, the embodiment is applicable to a cooking appliance. The control method of the cooking appliance provided by the embodiment of the invention can be executed by a control device in the cooking appliance, and the control device can be implemented in a form of hardware and/or software, for example, the control device can be configured in a controller of the cooking appliance.
Specifically, fig. 2 is a schematic structural diagram of a cooking appliance according to an embodiment of the present invention, and as shown in fig. 2, the cooking appliance includes a box 10 and a cooking cavity 11 disposed inside the box 10, a device accommodating cavity 12 is formed between the box 10 and the cooking cavity 11, and a heat dissipation fan 13 and a temperature sensor 14 are disposed in the device accommodating cavity 12.
The cooking appliance may be a box-shaped cooking utensil, and a heating pipe may be disposed inside the box body to realize a heating function, wherein the cooking appliance may be a steam box, an oven, or a steam oven, and the like, which is not limited in the embodiment of the present invention.
With continued reference to fig. 2, the cooking cavity 11 is used for placing food to be cooked to heat the food to be cooked, and for example, a food carrier such as a baking tray or a grill may be disposed in the cooking cavity 11 to carry the food to be cooked. The device accommodating cavity 12 is used for accommodating components such as a power panel and a controller so as to realize functions of controlling and heating the cooking appliance.
Continuing to refer to fig. 2, in the working process of the cooking appliance, the heat in the cooking cavity 11 is dissipated to the device accommodating cavity 12 through the cavity outer wall 111, in this embodiment, the heat dissipation fan 13 may be disposed in the device accommodating cavity 12, and the heat dissipation fan 13 is configured to discharge the heat in the device accommodating cavity 12, so as to reduce the temperature of each component inside the device accommodating cavity 12 and prolong the service life of the component.
For example, as shown in fig. 2, a heat dissipation air duct bottom plate 15 and a heat dissipation air duct cover plate 16 may be disposed in the device accommodation chamber 12, the heat dissipation air duct bottom plate 15 and the heat dissipation air duct cover plate 16 form a heat dissipation air duct, and the heat dissipation fan 13 may be disposed at the rear end of the heat dissipation air duct, when the heat dissipation fan 13 is turned on, an impeller of the heat dissipation fan 13 rotates to generate thrust, so as to blow heat in the device accommodation chamber 12 out of the box 10 through the heat dissipation air duct, thereby ensuring that the temperature rise of each component in the device accommodation chamber 12 does not exceed the standard.
With continued reference to fig. 2, a temperature sensor 14 is disposed in the device accommodating cavity 12, and the temperature sensor 14 is used for detecting the temperature in the device accommodating cavity 12 in real time, wherein the position of the temperature sensor 14 may be set according to actual requirements, for example, as shown in fig. 2, the temperature sensor 14 is disposed on the heat dissipation air duct cover plate 16, but is not limited thereto.
With continued reference to fig. 1, the present invention provides a method for controlling a cooking appliance, comprising:
and S110, acquiring the temperature of the device accommodating cavity through a temperature sensor.
The temperature sensor may be any type of temperature sensor as long as the temperature sensor can detect the temperature in the device accommodating cavity, and those skilled in the art can set the temperature sensor according to actual needs.
In this embodiment, the temperature in the device accommodating cavity can be obtained in real time through the temperature sensor, so as to adjust the working state of the cooling fan in time according to the real-time temperature in the device accommodating cavity, but the invention is not limited thereto.
In other embodiments, the temperature in the device accommodating chamber may be intermittently acquired by the temperature sensor, thereby contributing to reduction in power consumption.
S120, determining a target working parameter value of the cooling fan according to the temperature of the device accommodating cavity, wherein the target working parameter value comprises a target rotating speed and/or a target operation time, and the higher the temperature of the device accommodating cavity is, the larger the target working parameter value of the cooling fan is.
It can be understood that the larger the rotation speed of the cooling fan is, the larger the thrust generated by the rotation of the impeller of the cooling fan is, and the better the cooling effect is; and the longer the running time of the cooling fan is, the more the heat in the device accommodating cavity is discharged, and the better the cooling effect is.
In this embodiment, when the temperature in the device accommodating cavity that temperature sensor detected is lower, the ambient temperature that the device accommodated the intracavity components and parts is within the safe value, then can set up lower heat dissipation fan's target operating parameter value, set up heat dissipation fan's target rotational speed and/or target operating duration promptly and be less, so that heat dissipation fan operates with lower rotational speed and/or intermittent operation, can not open heat dissipation fan even, in order to reduce the inside and outside difference in temperature of culinary art cavity, and then reduce the heat in the culinary art cavity and scatter and disappear, reduce cooking utensil's energy consumption.
It can be understood that if the heat preservation performance of the cooking cavity is better or the temperature inside the cooking cavity is lower, the temperature inside the accommodating cavity of the device detected by the temperature sensor can be always within the safe temperature range, and the heat dissipation fan can not be started or run at low speed for a long time, so that the loss of the whole heat can be greatly reduced, and the energy consumption of the cooking appliance is greatly reduced.
Further, when the temperature of the device accommodating cavity detected by the temperature sensor is high, the ambient temperature of the device accommodating cavity component exceeds a safety value, a high target working parameter value of the heat dissipation fan can be set, namely the target rotating speed and/or the target running time of the heat dissipation fan are set to be high, so that the heat dissipation fan runs at a high rotating speed and/or continuously runs, heat in the device accommodating cavity is discharged out of the device accommodating cavity, the temperature rise of the device accommodating cavity component is guaranteed not to exceed the standard, and the service life of the device is prolonged.
S130, controlling the cooling fan to operate at the target working parameter value.
The target rotating speed and/or the target running time are/is executed by controlling the heat dissipation fan, so that the heat dissipation fan is controlled to work at a proper rotating speed and/or running time according to the actual temperature in the device accommodating cavity instead of continuously running at a high speed, the temperature rise of components in the device accommodating cavity is not overproof, the heat loss in the cooking cavity can be reduced, and the energy consumption of the cooking appliance is reduced.
It can be understood that the working state of the cooling fan is adjusted by the temperature of the device accommodating cavity detected by the temperature sensor, and therefore, the arrangement position of the temperature sensor may affect the cooling effect of the cooling fan.
In this embodiment, optionally, as shown in fig. 2, the temperature sensor 14 may be disposed above the cooking cavity 11, wherein, since heat is mainly conducted upwards along the outer wall 111 of the cooking cavity, the temperature sensor 14 disposed above the cooking cavity 11 may be more sensitive to temperature rise detection, thereby contributing to improving sensitivity of temperature monitoring, and opening or improving a target operating parameter value of the cooling fan 13 in time, so as to ensure that temperature rise of components in the device accommodating cavity 12 does not exceed a standard.
In other embodiments, the position of the temperature sensor 14 may also be set according to the position of a component with a large heat dissipation requirement, for example, as shown in fig. 2, a power panel 17 is disposed above the cooking cavity 11, and a controller and other components are disposed on the power panel 17, so that if the heat dissipation requirement of the power panel 17 needs to be met, the temperature sensor 14 may be disposed near the power panel 17, or may be directly disposed on the power panel 17, so as to accurately measure the ambient temperature of the power panel 17, and ensure that the temperature rise of the components on the power panel 17 does not exceed the standard.
In summary, in the control method of the cooking appliance provided in the embodiment of the present invention, the temperature sensor is used to obtain the temperature in the device accommodating cavity, and the target operating parameter value of the heat dissipation fan is determined according to the temperature in the device accommodating cavity, and the higher the temperature in the device accommodating cavity is, the larger the target operating parameter value of the heat dissipation fan is, so that when the ambient temperature of the components in the device accommodating cavity is within the safety value, the heat dissipation fan is controlled to operate at a lower rotation speed and/or operate intermittently, even the heat dissipation fan is not turned on, thereby ensuring that the temperature rise of the components in the device accommodating cavity does not exceed the standard, reducing the internal and external temperature difference of the cooking cavity, further reducing the heat dissipation in the cooking cavity, and reducing the energy consumption of the cooking appliance.
Optionally, determining a target operating parameter value of the cooling fan according to the temperature of the device accommodating cavity includes:
and when the temperature of the device accommodating cavity is smaller than a first temperature threshold value, determining that the target working parameter value of the cooling fan is a preset minimum parameter value.
And when the temperature of the device accommodating cavity is greater than or equal to the first temperature threshold value, determining that the target working parameter value of the cooling fan is greater than the preset minimum parameter value.
The first temperature threshold may be set according to a rated operating temperature of a component in the device accommodating cavity, which is not limited in the embodiment of the present invention.
It can be understood that when the ambient temperature of the device accommodating cavity is less than the first temperature threshold, the device in the device accommodating cavity is within the safe ambient temperature range, that is, the ambient temperature of the device is not over standard; when the ambient temperature that the device held the chamber was greater than or equal to first temperature threshold, the device held the components and parts of intracavity and is in under the higher temperature environment, and components and parts place ambient temperature exceeds standard promptly, at this moment, can influence the working property and the life of components and parts.
Further, the preset minimum parameter value is a minimum rotation speed and/or a minimum operation time that can be achieved by the cooling fan, for example, the minimum rotation speed is set to 0, and the minimum operation time is set to 0, at this time, the cooling fan is not turned on, and energy consumption can be reduced to the maximum extent.
In this embodiment, when the temperature that the device holds the chamber is less than first temperature threshold, it indicates that the device holds the components and parts of intracavity and is in safe environment temperature range, and at this moment, cooling fan need not to open, or cooling fan carries out work with lower rotational speed and/or shorter operating duration, can satisfy the heat dissipation demand that the device held the intracavity components and parts, consequently, can confirm that cooling fan's target operating parameter value is predetermined minimum parameter value to reduce cooking utensil's energy consumption.
Further, when the temperature of the device accommodating cavity is greater than or equal to the first temperature threshold, the ambient temperature of the device accommodating cavity is beyond the limit, at the moment, the cooling fan needs to be started, and the target working parameter value of the cooling fan is set to be greater than the preset minimum parameter value, so that the target rotating speed and/or the target running time of the cooling fan are/is increased, the temperature of the device accommodating cavity is rapidly reduced, and the working performance of each device in the device accommodating cavity is guaranteed.
Optionally, when the temperature of the device accommodating cavity is greater than or equal to the first temperature threshold, determining that a target operating parameter value of the cooling fan is greater than a preset minimum parameter value, including:
and when the temperature of the device accommodating cavity is greater than or equal to the second temperature threshold value, determining the target working parameter value of the cooling fan as a preset maximum parameter value.
And when the temperature of the device accommodating cavity is smaller than the second temperature threshold value, determining that the target working parameter value of the cooling fan is larger than the preset minimum parameter value and smaller than the preset maximum parameter value.
Wherein the second temperature threshold is greater than the first temperature threshold.
The second temperature threshold may be set according to a rated operating temperature of a component in the device accommodating cavity, which is not limited in the embodiment of the present invention.
It can be understood that, when the ambient temperature of the device accommodating cavity is greater than or equal to the second temperature threshold, the component in the device accommodating cavity is in an unsafe ambient temperature range, that is, the ambient temperature of the component exceeds the temperature range that the component can bear, and the component may be damaged if the component is in a temperature environment greater than or equal to the second temperature threshold for a long time.
Furthermore, the preset maximum parameter value is the maximum rotating speed and/or the maximum operation time which can be reached by the cooling fan, and the cooling fan can carry out cooling to the maximum extent by working at the maximum rotating speed and/or the maximum operation time so as to rapidly reduce the temperature of the device accommodating cavity.
In this embodiment, when the temperature of the device accommodating cavity is greater than or equal to the second temperature threshold, it indicates that the device in the device accommodating cavity is within the unsafe environment temperature range, and at this time, the cooling fan is controlled to operate at the maximum rotation speed and/or the maximum operation time, so as to rapidly reduce the temperature of the environment where the device is located and avoid damage to the device.
Furthermore, when the temperature of the device accommodating cavity is greater than or equal to the first temperature threshold and less than the second temperature threshold, the target working parameter value of the cooling fan is set and determined to be greater than the preset minimum parameter value and less than the preset maximum parameter value, so that the cooling fan is controlled to work at a proper target rotating speed and/or target running time according to the actual temperature of the device accommodating cavity, and the energy consumption of the cooking appliance is reduced while the heat dissipation requirement of the device accommodating cavity is met.
Optionally, when the temperature of the device accommodating cavity is smaller than the second temperature threshold, it is determined that the target operating parameter value of the cooling fan is greater than a preset minimum parameter value and smaller than a preset maximum parameter value, including:
a difference between the temperature of the device receiving cavity and the first temperature threshold is determined.
And determining a target working parameter value of the cooling fan according to the difference, wherein the larger the difference is, the larger the target working parameter value of the cooling fan is.
Specifically, the temperature of the device accommodating cavity detected by the temperature sensor is T, the first temperature threshold is sigma, and the second temperature threshold is delta, wherein sigma is less than delta. It is understood that the greater the difference T- σ between the temperature T of the device accommodating chamber and the first temperature threshold σ, the higher the temperature T of the device accommodating chamber.
In this embodiment, when the temperature of the device accommodating cavity is greater than or equal to the first temperature threshold and less than the second temperature threshold, the larger the difference T- σ between the temperature T of the device accommodating cavity and the first temperature threshold σ is, the larger the target operating parameter value of the heat dissipation fan is set, that is, the larger the target rotation speed and/or the target operation time of the heat dissipation fan is, so as to control the heat dissipation fan to operate at a sufficient target rotation speed and/or target operation time according to the actual temperature of the device accommodating cavity, thereby meeting the heat dissipation requirement of the component.
It should be noted that the specific implementation manner for determining the target operating parameter value of the cooling fan according to the difference value may be set according to actual requirements.
For example, a relationship between the difference and the target operating parameter value may be stored in advance, and after determining the difference between the temperature of the device-receiving cavity and the first temperature threshold, the target operating parameter may be calculated directly from the difference and the relationship.
In other embodiments, the temperature range between the first temperature threshold σ and the second temperature threshold δ may also be divided into at least two temperature intervals, each temperature interval is provided with a corresponding target operating parameter value, and the temperature of the device accommodating cavity may be determined in which temperature interval the temperature is located according to the difference, so as to determine the corresponding target operating parameter value.
For example, the cooling fan can be set to have 3 gear speeds, namely R1 (low gear), R2 (medium gear) and R3 (high gear), wherein R3 > R2 > R1. Meanwhile, the cooling fan is set to have the running time of 3 gears, namely t1 (low gear), t2 (medium gear) and t3 (high gear), wherein t3 is more than t2 and more than t 1.
Further, dividing a temperature range between the first temperature threshold value sigma and the second temperature threshold value delta into two temperature intervals, namely sigma to (delta-sigma)/2 and (delta-sigma)/2 to delta, wherein the target rotating speed corresponding to the temperature interval sigma to (delta-sigma)/2 is R1 (low gear), and the target operation time corresponding to the temperature interval sigma to (delta-sigma)/2 is t1 (low gear); the temperature range (δ - σ)/2- δ corresponds to a target rotation speed R2 (middle gear) and a target operating time t2 (middle gear).
After determining the difference T-sigma between the temperature T of the device accommodating cavity and the first temperature threshold sigma, comparing the value between T-sigma and (delta-sigma)/2, if (T-sigma) < (delta-sigma)/2, the temperature T of the device accommodating cavity is located in a temperature range sigma to (delta-sigma)/2, the corresponding target rotating speed is R1 (low gear), the corresponding target running time is T1 (low gear), and at the moment, the cooling fan is controlled to run at the rotating speed R1, and the running time is T1. Similarly, if (T- σ) ≧ δ - σ)/2, the temperature T of the device accommodating cavity is located in the (δ - σ)/2- δ temperature range, the corresponding target rotation speed is R2 (middle gear), the corresponding target operation time is T2 (middle gear), and at this time, the cooling fan is controlled to operate at the rotation speed R2, and the operation time is T2.
Further, when the temperature of the device accommodating cavity is greater than or equal to the second temperature threshold, it is determined that the target rotation speed of the cooling fan is R3 (high stage), and the target operation time is t3 (high stage), where the rotation speed R3 and the operation time t3 are preset maximum parameter values of the cooling fan.
It should be noted that the above solutions are only examples, in practical applications, the temperature range between the first temperature threshold σ and the second temperature threshold δ may be divided into more temperature intervals, and accordingly, the cooling fan includes the rotation speed and/or the operation time of more gears, and those skilled in the art may set the temperature intervals according to actual requirements. It can be understood that the more temperature intervals are divided between the first temperature threshold value σ and the second temperature threshold value δ, the more the gear positions of the rotation speed and/or the operation time of the cooling fan are, the more the adjustment of the target operation parameter value of the cooling fan is made.
Optionally, the target operating parameter value of the cooling fan includes a target rotation speed and a target operation time.
As described in the above embodiment, when the temperature of the device accommodating chamber is increased, the target rotation speed and the target operation time of the heat dissipation fan may be increased at the same time, that is, the higher the temperature of the device accommodating chamber is, the higher the target rotation speed of the heat dissipation fan is, the longer the target operation time is.
In this embodiment, adjust radiator fan's target rotational speed and target operating duration simultaneously according to the temperature that the device held the chamber, when the temperature that the device held the chamber risees, can promote radiator fan's heat-sinking capability by a relatively large margin to reach the effect that reduces the temperature that the device held the intracavity fast, guarantee the device and hold the working property of each components and parts of intracavity portion. Meanwhile, when the temperature of the device accommodating cavity is reduced, the power consumption of the cooking utensil can be greatly reduced, so that the energy-saving requirement is met.

In this embodiment, only one of the target rotation speed and the target operation time of the cooling fan may be adjusted according to the temperature of the device accommodating cavity, and when the cooling performance of the cooling fan fails to meet the cooling requirement of the device accommodating cavity, the other one of the target rotation speed and the target operation time is adjusted, so that the target operating parameter value of the cooling fan may be adjusted more finely.
For example, taking the target operating parameter value as the target rotation speed and the additional operating parameter value as the target operation time, when the temperature of the device accommodating cavity is increased, only the target rotation speed of the cooling fan is increased, and the target operation time is not changed. When the target rotating speed of the cooling fan is increased to the maximum rotating speed, and the cooling fan operates the target operation time at the preset maximum rotating speed, the temperature of the device accommodating cavity is still larger than or equal to the second temperature threshold value, and then the target operation time of the cooling fan is increased.
Or, taking the target operating parameter value as the target operating time and the additional operating parameter value as the target rotating speed as an example, when the temperature of the device accommodating cavity is increased, only the target operating time of the cooling fan is increased, and the target rotating speed is unchanged. When the target operation time of the cooling fan is increased to the maximum operation time, and the cooling fan operates at the target rotation speed for the preset maximum operation time, the temperature of the device accommodating cavity is still larger than or equal to the second temperature threshold value, and then the target rotation speed of the cooling fan is increased.
Optionally, the cooking appliance further comprises an alarm device.
After controlling the cooling fan to operate with the target working parameter, the method further comprises the following steps:
and when the temperature of the device accommodating cavity is greater than or equal to the second temperature threshold value and the target working parameter value is a preset maximum parameter value, controlling an alarm device to alarm.

Meanwhile, the setting position of the alarm device can also be set according to actual requirements, for example, the alarm device can be arranged in the device accommodating cavity, and further, the alarm device can be arranged on the power panel, but the invention is not limited to this.
It should be noted that, after the cooling fan operates at the maximum rotation speed for the maximum operation time, the temperature of the device accommodating cavity is still greater than or equal to the second temperature threshold, that is, even if the cooling fan operates at a high speed, the ambient temperature value in the device accommodating cavity is not reduced, and the cooking appliance may be in an abnormal operating state. At this time, the temperature of the device accommodating cavity detected by the temperature sensor always exceeds a safety range, and potential safety hazards may exist. In the embodiment, the alarm device is controlled to give an alarm to prompt a user to pay attention to the working state of the cooking appliance, so that the abnormity can be timely eliminated, and the safety performance of the cooking appliance is improved.
