Example 1
According to an embodiment of the present invention, there is provided an embodiment of a method for controlling a cooking appliance, it is noted that the steps illustrated in the flowchart of the drawings may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be executed in an order different from that herein.
Fig. 1 is a flowchart of a control method of a cooking appliance according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, acquiring the current moisture content and the target moisture content of the food in the cooking utensil.
Wherein the target moisture content is the moisture content of the food when the cooking appliance stops cooking.
The cooking appliances in the steps can be a steam box, an oven, a steam oven and other cooking appliances with the functions of steaming and baking.
The food in the above steps can be various types of food, such as meat, vegetables, etc., and the type of food is not limited herein.
The current water content of the food in the above steps can be obtained by an instrument or a sensor which can detect the water content, such as a water activity probe, a moisture meter and the like.
In an alternative embodiment, the target moisture content of the food may be determined according to the type of food. Wherein the type of food can be determined by means of image recognition.
In yet another alternative embodiment, the target moisture content may be set by the user, for example, the target moisture content may be determined according to the options of the target moisture content on the cooking utensil, and may also be determined according to the adjustment button of the target moisture content on the cooking utensil, so that the user can freely select the target moisture content to be reached by the food.
In another alternative embodiment, the user may select the food type according to the food type option, and after determining the food type, the cooking appliance may receive a signal corresponding to the food type, and determine a target moisture content corresponding to the food type according to the signal, so as to improve the intelligence of the cooking appliance while satisfying the user requirement.
And step S104, controlling the working parameters of the cooking appliance based on the current moisture content and the target moisture content.
Wherein, the working parameter comprises at least one of the following: a first operating period of a steam generator in the cooking appliance, a second operating period of a heating element in the cooking appliance.
The steam generator in the above step may be a steam generator with a heating function, and when the steam generator is operated, the heating element in the cooking appliance may not be operated, and the steam generator may achieve a steam heating effect in the cooking appliance. The heating element in the above step may be a heating tube, by which a roasting effect may be achieved in the cooking appliance.
The above steps wherein the steam generator is operated to increase the current moisture content of the food and the heating element is operated to decrease the current moisture content of the food.
In an alternative embodiment, the operating parameters of the cooking appliance within the preset period may be controlled based on the current moisture content and the target moisture content, wherein the cooking time period of the cooking appliance may include at least one preset period, and the duration of the preset period may be set by a user. For example, the cooking time period may be 30 minutes, the preset period may have a time period of 5 minutes, and in one preset period, if the current moisture content is greater than the target moisture content, the second operation time period of the heating element may be controlled to be 5 minutes, and the first operation time period of the steam generator may be controlled to be 0 minute; if the current moisture content is less than the target moisture content, the first operating time of the steam generator may be controlled to be 5 minutes and the second operating time of the heating element may be controlled to be 0 minutes, and the operating parameters of the cooking appliance may be controlled for one or more preset periods.
Through the above embodiments of the present invention, the current moisture content and the target moisture content of the food in the cooking appliance may be obtained, and then the operating parameters of the cooking appliance may be controlled based on the current moisture content and the target moisture content, where the operating parameters include at least one of the following: the first working time of the steam generator in the cooking appliance and the second working time of the heating element in the cooking appliance realize the real-time control of the working parameters of the cooking appliance according to the current moisture content and the target moisture content of food in the cooking process. It is easy to notice that under the condition that the current moisture content is less than the target moisture content, the first working time of the steam generator can be controlled to be increased to supplement the moisture content in the food, so as to keep the taste of the food to be in the optimal state, and under the condition that the current moisture content is greater than the target moisture content, the second working time of the heating element can be controlled to be increased to reduce the moisture content in the food, so that the taste of the food can be kept to be in the optimal state without any operation of a user in the process of moisture intervention on the food, the intelligence of the cooking appliance is improved, and the technical problem that the intelligence of the cooking appliance in the process of moisture intervention on the food in the prior art is low is further solved.
Optionally, controlling an operating parameter of the cooking appliance based on the target moisture content and the current moisture content comprises: obtaining a difference value between the current moisture content and a target moisture content to obtain a target difference value; judging whether the target difference value is within a preset interval or not; if the target difference value is within the preset interval, controlling the working parameters of the cooking appliance to be kept unchanged; and if the target difference value is not within the preset interval, adjusting the working parameters of the cooking appliance.
The target difference in the above step may be a difference of the current moisture content minus the target moisture content. The preset interval in the above steps may be set by a user, or may be a preset fixed interval.
In an optional embodiment, when the target difference is within the preset interval, the difference between the current moisture content of the food in the cooking appliance and the moisture content of the target moisture content is small, and the current moisture content of the food does not affect the mouthfeel of the food basically.
In another alternative embodiment, when the target difference is not within the preset interval, the current moisture content of the food in the cooking appliance is greatly different from the moisture content of the target moisture content; the current moisture content of food in the cooking appliance is far larger than the target moisture content, and the current moisture content of food in the cooking appliance is far smaller than the target moisture content.
Optionally, adjusting an operating parameter of the cooking appliance comprises: judging whether the target difference value is smaller than a first preset threshold value or larger than a second preset threshold value, wherein the first preset threshold value is the minimum value in a preset interval, and the second preset threshold value is the maximum value in the preset interval; if the target difference is smaller than a first preset threshold, controlling the proportion of the first working time length in the time length to be cooked to increase, and/or controlling the proportion of the second working time length in the time length to be cooked to decrease; and if the target difference is larger than a second preset threshold, controlling the proportion of the second working time length in the time length to be cooked to increase, and/or controlling the proportion of the first working time length in the time length to be cooked to decrease.
The time period to be cooked in the above steps may be the total cooking time period minus the time period of having been cooked in the cooking appliance. For example, if the total cooking time in the cooking appliance is 1 hour, the cooked time is 20 minutes, and the time to be cooked may be 40 minutes.
In an alternative embodiment, the current moisture content of the food may be brought to the target moisture content by controlling the first operating period of the steam generator and the second operating period of the heating element within the cooking appliance under the condition that the first power of the steam generator and the second power of the heating element are determined, so as to keep the taste of the food to be in an optimal state.
In another alternative embodiment, it may be determined whether the target difference is smaller than a first preset threshold, and in the case that the target difference is smaller than the first preset threshold, it indicates that the current moisture content of the food in the cooking appliance is smaller than the target moisture content, resulting in that the target difference is smaller than the first preset threshold; at this time, the ratio of the first working time of the steam generator in the cooking appliance to the waiting cooking time needs to be controlled to be increased, and/or the ratio of the second working time of the heating element to the waiting cooking time needs to be reduced, so that the current moisture content of the food is improved, and the taste of the food can reach the optimal taste.
For example, in the case that the target difference is smaller than the first preset threshold, at this time, the ratio of the first operating time period of the steam generator to the cooking time period is increased to a%, and the ratio of the second operating time period of the heating element to the cooking time period is decreased to B%, wherein a% + B% is 100%.
In yet another alternative embodiment, it may be determined whether the target difference is greater than a second preset threshold, and in the case that the target difference is greater than the second preset threshold, it indicates that the current moisture content of the food in the cooking appliance is greater than the target moisture content, resulting in the target difference being greater than the second preset threshold; at this time, the ratio of the second working period of the heating element in the cooking appliance to the waiting cooking period needs to be controlled to be increased, and/or the ratio of the first working period of the steam generator to the waiting cooking period needs to be decreased, so as to reduce the current moisture content of the food and ensure that the taste of the food can reach the optimal taste.
In addition, when the target difference value is larger than a second preset threshold value, the food can be dried by improving the power of the heating element, and the current moisture content of the food can be reduced to the target moisture content after the cooking is finished.
Optionally, the operating parameters further comprise at least one of: adjusting an operating parameter of a cooking appliance, the first power of a steam generator in the cooking appliance, the second power of a heating element in the cooking appliance, comprising: judging whether the target difference value is smaller than a first preset threshold value or larger than a second preset threshold value; if the target difference is smaller than a first preset threshold value, controlling the first power to increase and/or controlling the second power to decrease; and if the target difference value is larger than a second preset threshold value, controlling the second power to increase, and/or controlling the first power to decrease.
In an alternative embodiment, the current moisture content of the food may be brought to the target moisture content by adjusting the first power of the steam generator in the cooking appliance and the second power of the heating element in the cooking appliance to maintain the optimal mouthfeel of the food, with the first operating period of the steam generator and the second operating period of the heating element being determined.
In another alternative embodiment, it may be determined whether the target difference is smaller than a first preset threshold; when the target difference is smaller than the first preset threshold, the current moisture content of the food in the cooking appliance is smaller than the target moisture content, so that the target difference is smaller than the first preset threshold; at this time, it is necessary to control the first power of the steam generator in the cooking appliance to be increased and/or the second power of the heating element to be decreased so as to increase the current moisture content of the food and ensure that the taste of the food can reach the optimal taste.
In yet another alternative embodiment, it may be determined whether the target difference is greater than a second preset threshold, and when the target difference is greater than the second preset threshold, it indicates that the current moisture content of the food in the cooking appliance is greater than the target moisture content, resulting in the target difference being greater than the second preset threshold; at this time, it is necessary to control the second power increase of the heating element in the cooking appliance and/or the first power decrease of the steam generator to reduce the current moisture content of the food, so as to ensure that the taste of the food can reach the optimal taste.
Alternatively, the proportion adjustment amounts of the first and second operating periods in the cooking period are determined based on the target difference, or the power adjustment amounts of the first and second powers are determined based on the target difference.
In an alternative embodiment, the target difference may be input to a data processing center in the cooking appliance for operation, and specifically, the data processing center may determine the ratio adjustment amount of the first operating time length and the second operating time length in the cooking time length by using a preset formula. Wherein the predetermined formula may be Δ H ═ - (lnaw-c) RT0Q ═ Δ H/R, Q ═ Pt, where aw is the current moisture content of the food, R and c are constants, R is the gas constant, T is0Is the absolute temperature, Δ H is the theoretical quantity of heat to be absorbed by the food, Q is the actual quantity of heat to be absorbed by the food, P is the power of the steam generator or heating element, and t is the operating time of the steam generator or heating element.
It should be noted that, when the power of the steam generator is determined, the operating time of the steam generator may be calculated according to the actual amount of heat to be absorbed by the food and the power of the steam generator, and at this time, the operating time of the heating element may be determined as the cooking time minus the operating time of the steam generator; when the working time of the steam generator is determined, the power of the steam generator can be calculated according to the actual amount of heat to be absorbed by the food and the working time of the steam generator, at this time, the working time of the heating element can be determined as the time to be cooked minus the working time of the steam generator, and the power of the heating element can be determined according to the actual amount of heat to be absorbed by the food and the working time of the heating element.
Optionally, obtaining a target moisture content of food within the cooking appliance comprises: acquiring a cooking mode of the cooking appliance and a type of food; the target moisture content is determined based on the cooking mode and the type of food.
The cooking mode of the cooking utensil in the above steps can be a baking mode and a steaming mode, and the type of the food can be meat and vegetables.
In an optional embodiment, the target moisture content of the same type of food in different cooking modes may be the same, the target moisture content of the same type of food in different cooking modes may be different, and a user may determine the target moisture content corresponding to the cooking mode and the type of food in advance according to his or her preference.
For example, the target moisture content of the meat in the roast mode may be 20% and the target moisture content of the meat in the steamed mode may be 30%. The target moisture content of the meat may be 20% in the roast mode and 20% in the steam mode.
Optionally, determining the target moisture content based on the cooking profile and the type of food comprises: acquiring a preset corresponding relation, wherein the preset corresponding relation is used for representing the corresponding target moisture content of the food type in the cooking mode; and determining the target moisture content based on the preset corresponding relation.
In an optional embodiment, the preset corresponding relationship may be set by a user in advance, and the optimum moisture content of the food in the cooking mode may be determined according to the cooking mode and the type of the food in the development stage, the optimum moisture content is taken as the target moisture content, and the corresponding relationship between each type of food and the target moisture content in each cooking mode is established according to the target moisture content.
Optionally, obtaining the current moisture content of the food within the cooking appliance comprises: the current moisture content of food in the cooking appliance is acquired within a preset period.
The preset period in the above steps may be freely set by the user, or may be a fixed preset period.
In an optional embodiment, if the user needs that the food taste in the cooking appliance can reach the optimal taste, the time of the preset period is set to be shorter, the current moisture content of the food in the cooking appliance is obtained through the shorter time at intervals, and the working parameters of the cooking appliance are controlled for many times according to the current moisture content, so that the nutrition loss of the food in the cooking appliance is avoided, and the food taste in the cooking appliance can more accurately reach the optimal taste.
For example, the cooking time period may be 30 minutes, the preset period may be set to 5 minutes, and then the cooking appliance is controlled once every 5 minutes, and 6 times of control of the cooking appliance are required during the cooking time period, so that the mouthfeel of food in the cooking appliance can be more accurately achieved to the optimal mouthfeel through multiple controls.
In another optional embodiment, if the user needs to save the electric quantity of the cooking appliance, the preset period time can be set longer, the current moisture content of food in the cooking appliance can be obtained through a longer time interval, the working parameters of the cooking appliance can be controlled for a few times, and the power consumption of the cooking appliance is reduced on the premise that the food taste can reach the proper taste.
For example, the cooking time period may be 30 minutes, and the preset period may be set to 10 minutes, so that the cooking appliance is controlled once at an interval of 10 minutes, and only 3 times of control of the cooking appliance is required in the cooking time period, thereby reducing the power consumption of the cooking appliance.
A preferred embodiment of the present invention will be described in detail with reference to fig. 2. As shown in fig. 2, the method may include the steps of:
step S201, starting a steam supply function when detecting that food is placed in a cooking appliance;
the cooking appliance in the above steps may be a steaming oven, an oven with a steam function or a steaming box with a baking function.
Step S202, acquiring the current moisture content of food in the cooking utensil;
in the above steps, the current moisture content of the food in the cooking appliance may be obtained by using the water activity probe.
Step S203, determining the target moisture content of food in the cooking utensil;
alternatively, the target moisture content corresponding to the optimal taste of the food may be determined according to the cooking mode and the kind of the food.
Step S204, the data processing center determines steam supply logic according to the current moisture content and the target moisture content;
in an alternative embodiment, the current moisture content and the target moisture content may be input to a data processing center in the cooking appliance for calculation, and specifically, the data processing center may determine the steam replenishment logic by using a preset formula. Wherein the predetermined formula may be Δ H ═ - (lnaw-c) RT0Q ═ Δ H/R, Q ═ PT where aw is the current moisture content of the food, R and c are constants, R is a gas constant, T is the absolute temperature,. Δ H is the theoretical quantity of heat to be absorbed by the food, Q is the actual quantity of heat to be absorbed by the food, P is the power of the steam generator or heating element, and T is the operating time of the steam generator or heating element.
In step S205, the steam generator and the heating element are controlled using steam replenishment logic.
The steam generator in the steps can heat water in the water tank in the cooking appliance, and water is supplemented to the cooking appliance in a high-temperature steam mode, so that the water content of food in the cooking appliance is increased.
The heating element in the above steps can heat the cooking utensil, thereby reducing the moisture content in the food in the cooking utensil.
The steam supplying logic in the above steps may be that, when the moisture content of the food is relatively high and exceeds the target moisture content of the optimal taste of the food, the steam supplying logic controls the steam generator to be out of operation in a preset period, controls the heating element to be fully operated in the preset period, and reduces the moisture content of the food by baking the food so that the moisture content of the food can reach the target moisture content of the optimal taste of the food. When the moisture content of the food is less and the target moisture content of the optimal taste of the food is not reached, the steam supply logic is to improve the working time of the steam generator in the preset period and reduce the working time of the heating element in the preset period, and the moisture content of the food can be improved by increasing the working time of the steam generator in the preset period, so that the moisture content of the food can reach the target moisture content of the optimal taste of the food.
