Detailed Description
In order to more clearly explain the overall concept of the present application, the following detailed description is given by way of example in conjunction with the accompanying drawings.
Based on the technical problems in the prior art, the embodiment of the application provides a method for controlling the temperature in an appliance of a food processing device, so that the change of the temperature in the appliance is controlled in a mode of continuously adjusting a temperature threshold, and the temperature in the appliance reaches a target temperature. Wherein the target temperature refers to a temperature corresponding to a food processing function that the user is attempting to trigger.
It should be noted that the food processing device referred to in the embodiments of the present application includes, but is not limited to, an air fryer, a juicer, a wall breaking machine, and the like. For food processing devices related to temperature adjustment in appliances, the method for controlling the temperature in the appliances provided by the embodiment of the application can be adopted to realize the corresponding adjustment process of the temperature in the appliances.
As shown in fig. 1, a flowchart of an exemplary method for controlling temperature in an appliance of a food processing device is provided according to an embodiment of the present application. The method includes S101 to S105.
S101, determining a target temperature corresponding to a food processing function, and determining an initial temperature threshold set according to the target temperature.
For the convenience of users, most food processing devices are usually provided with buttons, keys and the like for triggering corresponding functions, and the users can trigger the corresponding functions through the corresponding buttons, keys and the like. Wherein different functions of the food processing device often correspond to different temperatures.
Therefore, in the embodiment of the present application, in order to achieve a better food processing effect, before controlling the temperature in the appliance, it is necessary to determine the target temperature corresponding to the food processing function that the user tries to trigger. Wherein, the target temperature refers to the optimal or better processing temperature, processing temperature range and the like corresponding to the food processing function. In the embodiment of the present application, in the case of determining the food processing function, the corresponding target temperature may be determined based on the correspondence relationship between the function and the target temperature, which is generally set in advance.
In order to effectively realize the control of the temperature in the appliance and ensure the safety of the food processing device in the using process, the temperature in the appliance is often controlled according to the temperature threshold in the working process of the food processing device.
In consideration of the fact that the temperature in the appliance is mainly controlled by adjusting the temperature threshold in the embodiment of the present application, before the temperature threshold is adjusted, an initial temperature threshold set according to a target temperature, that is, a temperature threshold corresponding to a food processing function, needs to be obtained.
It should be noted that the food processing apparatus may obtain the target temperature and the initial temperature threshold corresponding to the food processing function from the matching relationship pre-stored locally, in the cloud, or in another device. In the embodiment of the present application, the obtaining manner and obtaining timing for obtaining the target temperature and the initial temperature threshold are not limited.
And S102, controlling the appliance to start heating or stop heating according to the size relation between the temperature in the appliance and the current temperature threshold.
For the case where the temperature threshold is one, the appliance may be controlled to start heating or stop heating according to the magnitude relationship between the temperature in the appliance and the current temperature threshold. For example, the appliance may be controlled to start heating when the temperature in the appliance is not greater than the temperature threshold, and the appliance may be controlled to stop heating when the temperature in the appliance is greater than the temperature threshold after heating. Or after the appliance is preheated, if the temperature in the appliance is greater than the temperature threshold, the appliance can be controlled to stop heating, and the temperature in the appliance is firstly reduced to be not greater than the temperature, and the appliance can be controlled to start heating.
For the case where the temperature threshold is two, the temperature threshold may include an upper temperature limit (i.e., a first threshold) and a lower temperature limit (i.e., a second threshold). Wherein the first threshold is greater than the second threshold. The food processing apparatus may control the appliance to start heating or stop heating according to the magnitude relationship between the temperature inside the appliance and the two temperature thresholds, and the specific implementation manner may refer to fig. 3 and S1021 and S1022 described below, which is not described herein again.
S103, if the variation trend of the temperature in the appliance is matched with the current temperature threshold, adjusting the current temperature threshold to enable the adjusted temperature threshold to be closer to the target temperature.
In embodiments of the present application, the trend of the temperature within the appliance may include a decrease in temperature and/or an increase in temperature. Recording the temperature in the appliance as a first temperature when the appliance stops heating, and after a first preset time, if the current temperature in the appliance is lower than the first temperature, the change trend of the temperature in the appliance is cooling; and recording the temperature in the appliance as a second temperature when the appliance starts to be heated, and after a second preset time, if the current temperature in the appliance is higher than the second temperature, the temperature in the appliance changes along the trend of increasing.
It should be noted that, in the working process of the food processing device, the temperature measurement module for realizing temperature detection in the food processing device can detect the change of the temperature in the appliance in real time or periodically, and record the temperature in the appliance at the moment when the appliance starts to heat and stops heating. For example, the sensed temperature may be stored in a storage module of the food processing device for data storage.
In order to ensure that the temperature control process in the appliance can be completed in a short time, the first preset time and the second preset time are generally small, for example, in one implementation, the first preset time and the second preset time can be set to be less than 10 seconds.
In the embodiment of the present application, the trend of the temperature change in the appliance is matched with the current temperature threshold, which may be:
if the temperature in the appliance is higher than the target temperature, the change trend of the temperature in the appliance is temperature reduction, and after the first preset time, the change trend of the temperature in the appliance is temperature rise, and the change trend of the temperature in the appliance is matched with the current temperature threshold.
Or, if the temperature in the appliance is lower than the target temperature, the variation trend of the temperature in the appliance is temperature rise, and after a second preset time, the variation trend of the temperature in the appliance is temperature decrease, and the variation trend of the temperature in the appliance is matched with the current temperature threshold.
It should be noted that, the above mentioned two implementations indicating that the variation trend of the temperature in the appliance matches the current temperature threshold are exemplified, but in the embodiment of the present application, the matching includes, but is not limited to, the above mentioned cases, and may also include other determination manners, which is not limited herein.
And S104, judging whether the difference between the adjusted temperature threshold and the target temperature exceeds a set threshold. If the difference between the adjusted temperature threshold and the target temperature does not exceed the set threshold, executing S105; otherwise, executing S102 and the subsequent corresponding steps until the temperature threshold is adjusted to be not more than the set threshold.
The set threshold may be set before the food processing apparatus leaves the factory, specifically, may be set based on a target temperature corresponding to different food processing functions of the food processing apparatus, or may be set based on performance of a heater in the food processing apparatus. In the embodiment of the present application, the manner of presetting the set threshold, the size of the set threshold, and the like are not limited.
And S105, finishing the adjustment process of the temperature threshold, and enabling the food processing device to continuously work to the end under the control of the current temperature threshold.
That is, after the adjustment of the temperature threshold is completed, the food processing apparatus may determine whether the adjustment of the temperature threshold is needed by the proximity of the adjusted temperature threshold to the target temperature. The adjusted temperature threshold is close to the target temperature, the temperature in the appliance can be controlled according to the current temperature threshold, the food processing effect of the food processing device can be guaranteed, the current temperature threshold can be kept, the temperature in the appliance can be controlled according to the current temperature threshold, and the work of the food processing device is finished.
Compared with the prior art, in the adjustment process of the temperature in the appliance, the temperature threshold can be adjusted for multiple times to adjust the temperature in the appliance in a progressive mode, so that the temperature in the appliance is stabilized near the target temperature in a short time.
In addition, in each temperature adjusting stage, the temperature in the appliance is adjusted in a manner of changing in a small range under the influence of the temperature threshold. The temperature adjusting phase may be considered as a phase divided according to the current temperature threshold, that is, during the time period in which the temperature threshold is not changed, the process of controlling the temperature in the appliance is considered as a temperature adjusting phase.
Therefore, by adopting the technical scheme provided by the embodiment of the application, the problem of poor cooking effect caused by large temperature fluctuation in the appliance in the adjustment process of the temperature in the appliance can be solved.
The following takes a case where the temperature threshold includes a first threshold and a second threshold as an example, and further describes the technical solution provided by the embodiment of the present application.
In the embodiment of the present application, before each temperature threshold adjustment process, the size relationship between the temperature threshold and the target temperature often directly affects the adjustment mode of the temperature threshold. Three specific implementations are exemplified below.
In one implementation, the first threshold before adjustment is not less than the target temperature, and the second threshold before adjustment is not greater than the target temperature.
That is, before the temperature threshold is adjusted, the target temperature corresponding to the food processing function is in the temperature interval formed by the first threshold and the second threshold, so in the embodiment of the present application, the temperature can be controlled to gradually reach a relatively small fluctuation temperature adjustment process from a relatively large fluctuation temperature adjustment process by adopting a manner of narrowing the temperature interval. That is, the adjusted first threshold may not be greater than the first threshold before adjustment and not less than the target temperature, and the adjusted second threshold may not be less than the second threshold before adjustment and not greater than the target temperature.
The contents described in the embodiments of the present application are further explained by taking twice temperature threshold adjustment as an example. Fig. 2 is a schematic diagram of an exemplary temperature threshold variation provided in the embodiment of the present application.
And heating the appliance, and controlling the appliance to stop heating when the temperature in the appliance is detected to be greater than the initial first threshold. And then, the temperature in the appliance continuously drops, the temperature in the appliance is detected to be lower than an initial second threshold at the T1 moment after the appliance stops heating, when the temperature in the appliance is detected to be higher than the temperature in the appliance at the T1 moment after the time of delta T1, the temperature in the appliance is determined to be increased, the initial temperature threshold is adjusted at the moment, and a first threshold after the first adjustment and a second threshold after the first adjustment are obtained. At this time, the temperature in the appliance continuously rises, and the first time after the temperature in the appliance is greater than the first time is that the appliance is controlled to stop heating, and the temperature threshold after the first time is adjusted at a corresponding time by adopting the similar way to the way of adjusting the initial temperature threshold, so as to obtain the temperature threshold after the second time of adjustment, namely the first threshold after the second time of adjustment and the second threshold after the second time of adjustment, and the specific implementation way is not repeated herein.
Because the first threshold after the second adjustment and the second threshold after the second adjustment are both close to the target temperature, the temperature threshold obtained finally in the adjustment process can be determined according to the temperature threshold after the second adjustment, so that the appliance can realize the food processing function under the control of the temperature threshold after the second adjustment.
In another implementation manner, neither the first threshold before adjustment nor the second threshold before adjustment is less than the target temperature.
That is, before the temperature threshold is adjusted, the target temperature corresponding to the food processing function is higher than the first threshold and the second threshold, and in this embodiment of the present application, the temperature may be controlled to gradually reach a value close to the target temperature from a higher value by gradually decreasing the values of the first threshold and the second threshold. Generally, the adjusted first threshold is not greater than the first threshold before adjustment and not less than the target temperature, and the adjusted second threshold is not greater than the second threshold before adjustment.
In practical operation, in order to ensure that the adjusted temperature threshold can control the temperature in the appliance to tend to be stable within a range between the target temperature and the upper temperature after the temperature threshold adjustment process is completed, in the embodiment of the present application, generally, after the second threshold is greater than the target temperature and gradually decreases and approaches the target temperature, the second threshold is adjusted to a value smaller than the target temperature, and a specific implementation process may refer to an example shown in fig. 3.
The contents described in the embodiments of the present application are further explained by taking twice temperature threshold adjustment as an example. Fig. 3 is a schematic diagram of an exemplary temperature threshold variation provided in the embodiment of the present application.
Similar to the example shown in fig. 2, the timing, the determining method, and the like for adjusting the temperature threshold may refer to the foregoing description, and are not repeated herein. Since the second threshold after the first adjustment is greater than the target temperature and already approaches the target temperature, that is, the difference between the target temperature and the second threshold is within the preset range, the second threshold needs to be adjusted to be less than the target temperature during the second adjustment in order to stabilize the temperature in the appliance.
On the basis of the adjustment manner shown in fig. 3, the adjustment manner shown in fig. 4 may also be adopted to adjust the temperature threshold. Fig. 4 is a schematic diagram of an exemplary temperature threshold variation provided for the embodiment of the present application. When the first threshold before adjustment and the second threshold before adjustment are not less than the target temperature, the first threshold after adjustment is equal to the second threshold before adjustment. For a specific adjustment manner, reference may be made to the related description of the adjustment manner shown in fig. 2 and fig. 3, which is not repeated herein.
In yet another implementation, neither the first threshold before adjustment nor the second threshold before adjustment is greater than the target temperature.
That is, before the temperature threshold is adjusted, the target temperature corresponding to the food processing function is lower than the first threshold and the second threshold, and in this embodiment of the present application, the temperature may be controlled to gradually reach a value close to the target temperature from a lower value by gradually increasing the values of the first threshold and the second threshold. Generally, the adjusted first threshold is not less than the first threshold before adjustment, and the adjusted second threshold is not less than the second threshold before adjustment and is not greater than the target temperature.
However, in practical operation, in order to ensure that the adjusted temperature threshold can control the temperature in the appliance to tend to be stable within a range above and below the target temperature after the temperature threshold adjustment process is completed, in the embodiment of the present application, the first threshold is generally adjusted to a value greater than the target temperature after the first threshold is smaller than the target temperature and gradually increases and approaches the target temperature.
The specific implementation process is similar to the principle of the example shown in fig. 3, except that the adjustment manner of the temperature threshold shown in fig. 3 is to adjust from high to low, and in the implementation manner, the adjustment manner of the temperature threshold is to adjust from low to high, which is not described herein again for the specific implementation process.
Further, similar to the example shown in fig. 4, in the implementation described above, when both the first threshold before adjustment and the second threshold before adjustment are not greater than the target temperature, the second threshold after adjustment may be equal to the first threshold before adjustment.
In the temperature threshold variation trends shown in fig. 2 to 4, the curves representing the values of the temperatures in the appliances are relatively smooth, but in the actual operation, the temperatures in the appliances detected at the respective time points may not be maintained in a smooth rising or falling trend due to the influence of the soaking fan. That is, the actual temperature curve often has certain fluctuation, oscillation, etc. (not shown in fig. 2 to fig. 4), but does not affect the implementation effect, etc. of the embodiment of the present application.
In the adjustment process of the actual temperature threshold, other implementation manners besides the above three implementation manners may also be adopted, which is not illustrated here.
In order to reasonably control the heating start and stop of the appliance, in the embodiment of the present application, the corresponding control operation may be implemented by combining the magnitude relationship between the value of the current temperature threshold and the temperature inside the appliance. On the basis of the implementation shown in fig. 1, the implementation shown in fig. 5 can also be realized. In step S102, the control of the appliance to start heating or stop heating according to the magnitude relationship between the temperature in the appliance and the current temperature threshold may be implemented as step S1021 or step S1022.
And S1021, if the current temperature in the appliance is not more than the current first threshold, controlling the appliance to start heating.
And S1022, if the current temperature in the appliance is greater than the current first threshold, the appliance is controlled to stop heating, and after the appliance is controlled to stop heating, if the current temperature in the appliance is less than the current second threshold, the appliance is controlled to start heating.
The manner in which the temperature in the appliance is controlled according to the embodiments of the present application is further described with reference to the temperature threshold adjustment process shown in fig. 4 by way of a specific example. Wherein the food processing device is an air fryer.
When a certain frying function is selected, the program sets a temperature threshold for controlling the temperature in the appliance according to the function, for example, the temperature point required by the function is 200 degrees, and the current temperature in the appliance is 220 degrees, then the upper and lower limit values of the initial temperature threshold corresponding to the function are set to be 222 degrees and 216 degrees respectively. When the temperature in the appliance is below 222 degrees, the product is heated at a power of 1400W. When the temperature in the appliance continuously rises and exceeds 222 ℃, the heating is stopped, and the temperature value at the moment is recorded as A. When passing by delta Ta(△TaLess than 10s), if the temperature in the appliance is less than a, then it is considered to be decreasingA warm state. The temperature continuously drops, when the temperature is lower than 216 ℃, the control device starts to heat and records the temperature value at the moment as B, when delta T passesb(△TbLess than 10s), if the temperature in the appliance is greater than B, the temperature is considered to be in a raised state. At this time, the upper and lower limits of the temperature threshold for controlling the temperature in the appliance are updated to 216 degrees and 211 degrees.
When the temperature in the appliance is below 216 degrees, the product is heated at a power of 1400W. When the temperature in the appliance continuously rises and exceeds 216 ℃, the heating is stopped, and the temperature value at the moment is recorded as C. When passing by delta Tc(△TcLess than 10s), a cooling state is assumed if the temperature inside the appliance is less than C. The temperature continuously drops, when the temperature is lower than 211 ℃, the appliance starts to heat, the temperature value at the moment is recorded as D, and when delta T passesd(△TdLess than 10s), if the temperature inside the appliance is greater than D, the temperature is considered to be in a raised state. At this time, the upper and lower limits of the temperature threshold for controlling the temperature in the appliance are updated to 211 degrees and 206 degrees.
And continuously updating the upper limit and the lower limit of the temperature threshold according to the above mode until the values of the upper limit and the lower limit are 201 degrees and 199 degrees.
