Description
Technical Field
The invention relates to the field of kitchen appliances, in particular to a control method, a cooking appliance and a computer readable storage medium.
Background
Some cooking appliances on the market can calculate calories of food taken by a user and inform the user of the calculation result, so that the user can timely and accurately know the calorie value contained in the food taken by the user. However, most of these cooking appliances can calculate and inform only the calorie value contained in the food currently taken by the user in real time. When a user needs to take food several times during a meal, the calorie value of the food taken at a later time may cover the result of the previous time. Therefore, when the user needs to know the total sum of the calorie values of the food taken in by the user in a meal, the calculation results of the calorie values notified each time the food is taken can only be manually accumulated, and the calorie values taken in the meal cannot be intuitively known, which brings about a bad use experience.
To this end, the present invention provides a control method, a cooking appliance and a computer-readable storage medium to at least partially solve the problems in the prior art.

It is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", and the like are used herein for purposes of illustration only and are not limiting.
The invention provides a cooking appliance. The cooking appliance according to the present invention may be an electric rice cooker, an electric pressure cooker, or other cooking appliances, and the cooking appliance according to the present invention may have various functions of cooking porridge, cooking soup, etc., in addition to the function of cooking rice.
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in fig. 1, the cooking appliance 1 according to the present invention may include a pot body 10 and a lid 20. The inner pot 11 is arranged inside the pot body 10. The inner pot 11 may be configured to be removably disposed in the pot body 10. For example, in one embodiment, a cylindrical inner pot receiving portion may be provided at the pot body 10, and the inner pot 11 may be freely put into or taken out of the inner pot receiving portion. The removable arrangement allows the user to conveniently remove the inner pan 11 for cleaning. Of course, in other embodiments, the inner pot 11 may be fixedly provided in the pot body 10 in an unreleasable manner. In addition, a heating module (not shown) for heating the inner pot 11 and the like are generally provided in the pot body 10.
The lid 20 is provided to the pot body 10 in an openable and closable manner. For example, the lid body 20 may be pivotably connected to the pot body 10 by a pivot shaft, so that the pot body 10 can be conveniently covered. When the lid body 20 is opened with respect to the pot body 10, the opening of the inner pot 11 in the pot body 10 is exposed, and the user can add ingredients to the inner pot 11 or take cooked food out of the inner pot 11. When the cover 20 is covered on the pot body 10, it covers the inner pot 11 and forms a cooking space 12 with the inner pot 11. A sealing member (not shown) is further provided between the cover body 20 and the inner pot 11 so that the cooking space 12 can maintain good sealing. It is understood that the pot body 10 and the cover 20 constitute a cooking appliance main body of the cooking appliance.
Further, the cooking appliance according to the present invention may further include a weighing module (not shown). The weighing module may be a weight sensor or the like. The weighing module is used to sense the weight of food within the cooking space 12. In one embodiment, a weighing module may be disposed in the pot body 10 below the inner pot 11, which may sense the weight of the inner pot 11 and the food therein as a whole after cooking is completed, and subtract the initial weight of the inner pot 11 from the sensed weight to obtain the weight of the food therein. As an alternative embodiment, the weighing module may also be provided at the bottom of the pot body 10. Which senses the weight of cooking appliance 1 and the food therein as a whole after cooking is complete and subtracts the initial weight of cooking appliance 1 from the sensed weight to obtain the weight of the food therein.
By arranging the weighing module, the weight of the food taken by the user can be acquired. For example, the weight value sensed by the weighing module in real time before and after the user takes food is subtracted to obtain the weight of the user taking food at a single time, and/or the weight value sensed by the weighing module in real time after cooking is completed and before the user takes food is subtracted to obtain the weight of the user taking food cumulatively.
In addition, the weighing module may be set to zero after cooking is completed, that is, before the user takes the food, the weighing module senses the initial weight of the inner pot 11 and the food (or the cooking appliance 1 and the food) in real time and sets to zero based on the initial weight. As such, the weight sensed by the weighing module is 0 when the user is not taking food. After the user takes the food, the weight value sensed by the weighing module is a negative value, and the absolute value of the weight value is the weight of the food taken by the user. In addition, the difference value of the weight values sensed by the weighing module before and after the user takes the food is the weight of the user taking the food once.
With continued reference to fig. 1, the cooking appliance 1 further comprises a control module 30, which may comprise a control circuit board. The control circuit board may have a control program, etc. pre-stored thereon, and be electrically connected with components, such as a heating module, a weighing module, etc., to control the above components based on the control program. For example, the control circuit board may have a calorie calculation program as described below prestored, which may calculate the calories contained in the food taken by the user based on the weight change of the food sensed by the weighing module.
Preferably, in the present embodiment, the control module 30 is disposed on the cover 20 and is located on the upper surface of the cover 20. With this arrangement, the user can easily operate the cooking appliance 1 when the lid body 20 is closed, and the space of the lid body 20 can be used reasonably.
Furthermore, the cooking appliance 1 may further include an operation module, such as an operation key or the like. The user may send the calorie calculation instruction to the control module 30 by performing a corresponding operation (e.g., triggering an operation key) on the operation module. The specific triggering manner may be that when the user triggers the operation key, the control module 30 detects that the level signal changes (for example, the high level signal changes to the low level signal or the low level signal changes to the high level signal), and the level signals collected for a predetermined number of times are all changed level signals, and at this time, the calorie calculation instruction is considered to be successfully received.
As an alternative embodiment, the above-described operation module may not be provided. The control module 30 is preferably configured to default to the calorie calculation program after cooking is complete.
Further, the cooking appliance 1 further comprises an informing module. The notification module is electrically connected to the control module 30 and is used for sending corresponding notification information to the user when the control module 30 obtains the result of the calorie calculation. As shown in fig. 1, as one example of the notification module, it may include a first display module 41 and a second display module 42. Specifically, the first display module 41 and the second display module 42 may be display screens or digital tubes, and both may send out notification information by displaying a manner such as characters or numbers.
Preferably, the first display module 41 may be configured to display the first calorie information according to the calculation result of the control module 30. Wherein, the first calorie information is the card corresponding to the food taken by the user at the current time (which may be called the calorie taken at the current time Kcal)i). The second display module is used for displaying the first calorie information according to the calculation result of the control module 30. Wherein the second calorie information is the calorie corresponding to the food which is taken by the user in an accumulated manner since the cooking is completed (may be called as an accumulated taken calorie Kcal)sum,i). Therefore, according to the present invention, during the process of taking food, the user can know the calorie corresponding to the food taken this time and the accumulated calorie corresponding to the food taken this time in detail through the first display module 41 and the second display module 42, and can provide an accurate and reliable basis for the user to adjust the diet. It is understood that the first calorie information and the second calorie information may be collectively referred to as calorie information.
In addition, the first display module 41 may be configured to display the first weight information according to a sensing result of the weighing module. Wherein, the first weight information is the weight delta G of the food taken at the current time represented by the weight change value sensed by the weighing module before and after the food taken at the current time is taken by the useri. The second display module is used for displaying second weight information according to the sensing result of the weighing module. Wherein the second weight information is weight Δ G of food for accumulationsum,i. Therefore, according to the present invention, during the process of taking food, the user can know the weight of the food taken this time and the accumulated weight of the food taken this time in detail through the first display module 41 and the second display module 42, and can provide an accurate and reliable basis for the user to adjust diet. It is understood that the first weight information and the second weight informationInformation may be collectively referred to as weight information.
In the present embodiment, the first display module 41 and the second display module 42 are provided on the pot body 10 and are located on the surface of the pot body 10 facing the lid body 20. Such an arrangement makes it possible for the user to conveniently observe the display results of the first and second display modules 41 and 42 when taking food out of the inner pot 11. The first display module 41 and the second display module 42 are formed by different display areas of the same display device (for example, a display screen or a nixie tube).
However, as an alternative embodiment, the first display module 41 and the second display module 42 may be configured by different display devices, respectively. And the two can be respectively arranged at different positions according to requirements. Alternatively, the notification module may be further configured as a display device including a display area through which the display device alternately displays the first calorie information and the second calorie information and/or the first weight information and the second weight information. The skilled person can flexibly select the arrangement.
In addition, the notification module may be configured as a speaker or the like to emit the calorie information and/or the weight information by voice broadcasting. Alternatively, the notification module may be a combination of the above-mentioned configurations, and the like, that is, it may include at least one of a display screen, a nixie tube, and a speaker.
The control method of the cooking appliance 1 for calculating calories of food taken by the user is described in detail below with reference to fig. 2.
When the user is ready to cook the desired ingredients or the like, the low sugar cooking function may be selected and cooking may be initiated by the control module 30. After cooking is completed, the control module 30 first determines whether a calorie calculation instruction is received. I.e. whether the operation module is operated by the user. When the card-in-path calculation instruction is not received, indicating that the user does not desire the operation of calorie calculation, the control module 30 may directly end the current control program. When the user operates the operation module and the control module 30 receives an instruction for calorie calculation, it controls the cooking appliance 1 to perform a control program for calorie calculation.
Preferably, the operation module may also be omitted, and the control module 30 is configured to automatically perform a control program of calorie calculation by default at the end of the cooking function.
After entering the control procedure of calorie calculation, the control module 30 may determine the calorie coefficient K of the currently cooked food according to the cooking information. The calorie coefficient K is used to characterize the calorie per unit weight of the food. Specifically, the cooking information may include the type of the food material cooked this time and the cooking function performed by the cooking this time. It is understood that different food materials contain different calorie values due to their different nutritional ingredients. While the cooking function is different for the same food material, the value of calorie contained in the food per unit weight after completion of cooking is also different. For example, the same kind of rice is cooked in a rice cooking manner to form rice, and the two kinds of food have different calorie values from the rice porridge cooking manner to form rice porridge.
In one embodiment, the calorie coefficient K of the food formed by the common ingredients after passing through different cooking functions may be stored in the control module 30 in advance before the cooking appliance 1 is shipped. The control module 30 may be invoked at any time. In addition, the calorie coefficient K may be input to the control module 30 by the user through manipulation of a key or the like after or before cooking is completed. Alternatively, the calorie coefficient K may be determined by connecting the control module 30 to a cloud server or the like, searching cooking information similar to or close to the current cooking from the cloud server, and downloading the corresponding calorie coefficient. In actual use, the calorie coefficient K may be determined in a combination of the above manners.
Preferably, while determining the calorie coefficient K, the control module 30 may control the weighing module to sense an initial weight G of food within the cooking space 120. The weighing module then performs a zeroing operation based on the initial weight. It is understood that the initial weight of the food in the cooking appliance 1 sensed by the weighing module through the above-described zeroing operation is displayed as 0. And, when the user getsAfter the food is consumed, the weight value sensed by the weighing module is substantially negative and its absolute value is equal to the weight of the food taken by the user. Therefore, the calorie calculation can be directly carried out through the absolute value of the sensing result of the weighing module, so that the calculation process is simpler. And, if the user desires, the user can also be informed of the sensing result of the weighing module as weight information through the informing module as described above, so that the user can intuitively and accurately know the weight of the food taken by the user without being subjected to calculation.
Further, the real-time weight of the food may continue to be sensed by the weighing module and the real-time weight information sent to the control module 30. As the user takes food, the weight of the food sensed by the weighing module decreases. In other words, when the weight of the food sensed by the weighing module is reduced, it may be determined that the user's operation of taking the food is currently generated. The control module 30 can determine the weight Δ G of the food taken by the user at the current time according to the weight values of the food sensed by the weighing modules before and after the food is taken by the useri。
Specifically, the weight of the food sensed by the weighing module before the weight of the food changes is Gi-1And the weight of the food sensed after the weight of the food is changed and restabilized is Gi. Therefore, Δ Gi＝Gi-1-GiThe weight of the food taken at the time can be characterized. Where i is the number of times the user takes food from the cooking appliance 1 in the meal, and i is 1, 2, 3 …. Preferably, the first weight information informing of the weight of the food taken at the time may be issued through the informing module.
Further preferably, after the food is taken for the time, the weight Δ G of the food taken in the meal can be obtained through the weight change sensed by the weighing module after zero settingsum,i. Since a zeroing operation is performed before, therefore, | GiI can represent the weight Δ G of the food taken cumulativelysum,i. Preferably, the second weight information informing of the weight of the food taken cumulatively may be issued by the informing module.
As an alternative implementationIn this way, the zero setting operation may not be performed. And the weight value sensed by the weighing module in real time is adopted to calculate the weight of the taken food. Wherein the weight of the food taken once can still pass the AGi＝Gi-1-GiAnd (6) calculating. And Δ G can be passed for cumulative food weightsum,i＝G0-GiAnd (6) calculating.
Still further, the control module 30 may be configured to determine the calorie factor K and the weight Δ G of the food currently consumed based on the calorie factor K and the weight Δ G of the food currently consumediCalculating calorie Kcal of food taken at presenti＝K*ΔGi. And can send out a notification of the calorie Kcal taken at the time through the notification moduleiThe first calorie information of. Therefore, the user can accurately and intuitively know the calorie value of the food taken at the time through the informing module.
In addition, the control module 30 may take the current calorie Kcal of food each time1、 Kcal2、Kcal3、Kcal14、Kcal5… …, the total calories of food taken from cooking utensil 1 are accumulated after the food is taken for the timesum，i. For example, Kcalsum，1＝Kcal1，Kcalsum，2＝Kcal1+Kcal2，Kcalsum，3＝Kcal1+ Kcal2+Kcal3… … and so on. And the control module 30 may issue a notice of the cumulative calories taken Kcal through the notification modulesum，iThe second calorie information of (1). Therefore, the user can accurately and intuitively know the total amount of the food taken in by accumulating the taken food in the process of the meal through the informing module.
As shown in FIG. 3, in another embodiment, the control module 30 may also directly calculate the cumulative calories burned, as shown in FIG. 3sum,iAnd calculating the calorie Kcal of the current time by subtractioni. As described above, after the user takes food from the cooking appliance 1, the weight sensed by the weighing module is Gi. If the zero setting operation is performed before, the user accumulates the fetching in the dining processCumulative amount of food taken Δ Gsum,i＝|GiL. If the zero setting operation is not executed, the user accumulates the accumulated food taking amount delta G in the current dining processsum,i＝G0-Gi。
The control module 30 may then calculate the cumulative amount Δ G based on the accumulated amount of usagesum,iDetermining the cumulative calorie Kcal of the food cumulatively taken by the user in the current dining process according to the calorie coefficient Ksum,iWherein Kcalsum,i＝K*ΔGsum,i. And the informing module sends out informing of the cumulative calorie Kcalsum,iThe second calorie information of (1).
In addition, the control module 30 can also use the cumulative calorie Kcal corresponding to the current food takensum,iSubtracting the cumulative calorie Kcal corresponding to the previous foodsum,i-1To obtain calorie Kcal of food taken at the current timei. And the informing module sends out informing that the calorie Kcal is taken at the timeiThe first card mileage information.
In addition, in the process of taking food out of the cooking appliance 1, the user may determine that the amount of food taken out at the time is too large according to the notification information sent by the notification module, and thus a part of food taken out at the time may be returned to the cooking appliance 1. During this process, the weight of the food sensed by the weighing module increases. In other words, when the weight of the food sensed by the weighing module increases, it may be determined that an operation of returning the food by the user is currently generated. The food is not eaten by the user, so the information of informing calories sent by the current informing module has deviation and needs to be corrected.
Specifically, the control module 30 may determine the increase Δ G of the food in the cooking appliance 1 according to the difference between the weight values of the food sensed by the weighing modules before and after the user returns the food respectivelyj. And determining the calorie corresponding to the portion of food returned based on the kale coefficient K, which may be referred to as a modified calorie Kcalx. Further, the calorie Kcal is taken at the current time informed by the current informing moduleiSubtract correction fromKcal caloriexTo obtain the calorie Kcal of the current timeiAnd informs the actual value through the informing module. And the cumulative calorie taken out is notified by the current notifying modulesum,iMinus corrected calorie KcalxTo obtain the cumulative calorie corresponding to the foodsum,iAnd informing the actual value through the informing module. Thereby, the display of calories is made more accurate.
In the process of sensing the decrease or increase in weight of the food (which may be generally referred to as a change in weight) by the above-described weighing module, it is preferable that the weighing module continuously senses the weight value of the food at intervals of the collection period M so as to sense the weight of the food in real time. And when the weight value of the food sensed by the weighing module for at least N collection periods M is stable, it can be considered that the change of the weight of the food is finished, that is, the operation of taking the food or returning the food by the user is finished. Where N may be referred to as a preset threshold. The control module 30 can determine the weight Δ G of the food to be taken according to the stable weight values measured by the weighing module before and after the weight changeiOr increase in food Δ Gj. Thereby, disturbances of the sensing result of the weighing module caused by the action of forces exerted by the user on the inner pan 11 during operation can be reduced or even eliminated.
It is understood that the weight value of the food sensed here may be that a plurality of weight values sensed in at least N acquisition cycles M are consistent, or that the maximum difference value of the plurality of weight values is within an allowable error range.
Preferably, the acquisition period M may be 0-50 ms. The acquisition period M may be 10ms, 20ms, 30ms, 40ms, 50ms or any value within the above range according to the usage habits of the user, the sensitivity of the weighing module, and the like. And, the preset threshold N may be 0 to 200. For example, the preset threshold N may be set to 50, 100, 150, 200 or any value within the above range according to the usage habits of the user, the sensitivity of the weighing module, and the like.
The control method according to the invention has been described above with reference to the flow chart shown in fig. 2. However, it is understood that the steps of the control method may have a different order than in the flowchart, for example, the steps of "determining the calorie coefficient" and "obtaining the weight of the food taken" may have no definite precedence relationship therebetween, and may be performed in an alternative order or simultaneously. In addition, the step of determining whether or not the calorie calculation instruction is received may be performed between the step of "determining the calorie coefficient" and the step of "obtaining the weight of the food for consumption", or may be performed simultaneously with both of them. As long as the above-described control method can be implemented.
In addition, the present invention also provides another cooking appliance, which includes a memory, a processor and a computer program stored in the memory and running on the processor, wherein the processor executes the program to implement the steps of the control method executed by the cooking appliance in fig. 2 and 3.
In addition, the present invention also provides a computer storage medium having a computer program stored thereon. The steps of the control method performed by the cooking appliance in the aforementioned fig. 2 and 3 may be realized when the computer program is executed by a processor. The computer storage media is, for instance, computer readable storage media.
