Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a water injection state display control system of a cooking appliance includes: the water quantity information display device comprises a controller 10 and a display device 20, wherein the display device 20 is connected with the controller 10, the controller 10 is used for obtaining a control signal corresponding to the water quantity information according to the weight information and the type information of cooking food materials in a cooking cavity of a cooking appliance and the water quantity information of the cooking cavity obtained in real time and sending the control signal to the display device 20, and the display device 20 is used for projecting corresponding information according to the control signal so as to inform a user of the cooking taste corresponding to the current water injection quantity.
Specifically, the controller 10 obtains the water volume threshold ranges corresponding to different cooking tastes according to the cooking food weight information and the cooking food type information corresponding to the cooking food in the cooking cavity, and then performs comparative analysis on the water volume information and each water volume threshold range according to the water volume information obtained in real time, so as to obtain the control signal of the water volume information and send the control signal to the display device 20. When receiving the start instruction, the controller 10 first determines whether the water injection amount display function is on. The water injection amount display function is to obtain the water amount threshold range corresponding to each cooking taste according to the cooking food weight information and the cooking food type information of the cooking food in the cooking cavity, and then the display device 20 displays different signals to inform the user of the operation when the water injection process is performed according to the water amount information within different water amount threshold ranges.
It can be understood that the types of the cooking tastes are not unique, the types of the cooking tastes are three, four, five or more, the types of the cooking tastes are more divided, and the more easily the user can obtain food suitable for the cooking tastes. For the same cooking food material, different cooking tastes can be finally obtained due to different injected water amount information in the cooking process, and each cooking taste corresponds to a water amount threshold range.
It should be noted that the type of the control signal corresponds to the number of water amount threshold ranges (or the type of cooking taste), and when the water amount information acquired in real time is located in different water amount threshold ranges, the controller 10 sends different control signals to the display device 20. For example, when there are three types of cooking tastes, there are three corresponding water volume threshold ranges, and when the water volume information is within one of the water volume threshold ranges, the controller 10 sends a corresponding control signal to the display device 20. According to the difference of the acquired water amount information, the controller 10 sends three different control signals to the display device 20 to control the display device 20 to display three different information, and the user can know the cooking taste corresponding to the current water injection amount according to the displayed information.
The manner in which the water filling amount display function is turned on is not exclusive as long as it can inform the controller 10 that the water filling amount display function is to be executed by a corresponding operation. For example, in one embodiment, a corresponding function selection key may be provided on the cooking appliance, and when the user needs to select the function to perform the water filling amount display operation, the user needs to press the key. That is, when water needs to be added into the cooking cavity during cooking by the user using the cooking appliance, the amount of water can be directly predicted by a conventional method, such as estimation using a scale mark or direct addition of water according to experience. Only when the user selects a more intelligent and accurate water injection mode, that is, the user starts the water injection amount display function, the corresponding display control is realized according to the corresponding operation method. When the user inputs a corresponding start instruction to start the water injection amount display function, the controller 10 further determines whether the water injection amount display function is started, that is, whether the corresponding device is started to operate, so as to avoid the occurrence of start-up failure and the like, thereby effectively ensuring the start-up reliability of the water injection amount display function.
It should be noted that referring to fig. 2, in one embodiment, the water filling state display control system of the cooking appliance further includes an alarm device 60, and the alarm device 60 is connected to the controller 10. Specifically, when the controller 10 determines whether the water injection amount display function is turned on, the controller 10 may also control the alarm device 60 to output alarm information to inform the user, and at the same time, the controller may return to the operation of determining whether the water injection amount display function is turned on when receiving the turn-on instruction, that is, the controller may control the turn-on by outputting the turn-on instruction again by the user.
After the water injection amount display function is turned on, the controller 10 determines whether the cooking material is added to the cooking cavity of the cooking appliance. In the actual operation process, after the user inputs a corresponding opening instruction to start the water injection amount display function, whether corresponding cooking food materials are added into the cooking cavity or not can be further judged, and subsequent water injection amount display operation can be carried out only when the cooking food materials are added.
When the cooking cavity has been filled with cooking ingredients, the controller 10 will start to perform an operation corresponding to the water filling amount display function. It should be noted that when the controller 10 analyzes that no food material is added to the cooking cavity, the operation of determining whether the water injection function is turned on is returned, that is, only when the food material is added to the cooking cavity, the controller 10 performs the subsequent operation of the water injection display function. It will be appreciated that in this embodiment, the controller 10 may also notify the user when no cooking material is added to the cooking cavity by sending an alarm message via the corresponding alarm device 60.
It is understood that the manner of acquiring the weight information of the cooking materials and the type information of the cooking materials is not unique. In the cooking process, after the user obtains the weight information of the cooking material through measurement by the external device, the weight information of the cooking material and the type information of the cooking material may be manually input to the controller 10. It is understood that in other embodiments, the detection may be automatically performed by a corresponding device provided in the cooking appliance.
For the same cooking food material, under different weights, the required water amount is inconsistent in order to obtain the same cooking taste; likewise, for different types of cooking ingredients, the amount of water required is not consistent in order to obtain the same or similar cooking mouthfeel at the same weight. That is, in the cooking process, when the weight and the kind of the cooking materials are consistent, the cooking taste of the cooking materials is mainly determined by the injected water amount. It should be noted that in one embodiment, the controller 10 is pre-programmed with expansion rate curves for different types of cooking ingredients, the expansion rate curves representing water absorption information for the different cooking ingredients. And analyzing and processing according to the water absorption information of different cooking food materials and the weight information of the cooking food materials, so as to obtain the water absorption and expansion conditions of all the cooking food materials in the cooking cavity. In the cooking process of the food materials, different mouthfeel information can be obtained after different water amounts absorbing water are cooked, so that the finally obtained cooking mouthfeel type of the food can be judged according to the amount of the water amount added into the cooking food materials. The user can intuitively obtain the finally obtained cooking taste under the water injection state through the information of the injected water amount.
The cooking appliance is provided with a display device 20, and when the water quantity information of the water injected into the cooking cavity by the user changes, the display device 20 can display different information according to the change of the water quantity information in real time. Specifically, the color of the emitted indication line or image can be changed, and the user can intuitively obtain the cooking taste matched with the color according to different colors. In order to facilitate understanding of the embodiments of the present application, the following explanation is made by using the indication lines or images with different colors as the corresponding information displayed by the display device 20. It will be appreciated that when the user stops adding water, the color displayed by the display means 20 will not continue to change and will maintain the color corresponding to the water amount information of the currently injected water until the user turns off the water injection amount display function, and the indication of the color will not disappear.
It should be noted that, in one embodiment, the controller 10 obtains a first water threshold range corresponding to the first type of mouth feel according to the weight information of the cooking food and the type information of the cooking food, and the first water threshold range is smaller than a first preset injected water amount. The first type of mouthfeel is mouthfeel information corresponding to the cooking of the cooking food material being not cooked, namely, because the corresponding water amount is small at the moment, the finally obtained food is not cooked and can not be eaten under the water amount corresponding to the water amount threshold range. In order to facilitate understanding of the correspondence between various tastes and the water amount information, the following explanation will be given with respect to cooking, where the first kind of taste is undercooked taste, and undercooked rice will be obtained finally when cooking is performed with a water amount smaller than the first preset water injection amount.
And obtaining a second water volume threshold range corresponding to the second type of mouthfeel according to the weight information and the type information of the cooking food materials, wherein the second water volume threshold range is larger than or equal to the first preset water injection volume and smaller than the second preset water injection volume. In the case of rice cooking, the second category of texture is harder texture information. When a user cooks rice, if the added water amount information is between the first preset water injection amount and the second preset water injection amount, the finally obtained rice can be eaten, but the taste is hard, and the water amount corresponding to the water amount threshold range is suitable for the user who likes hard rice.
And obtaining a third water volume threshold range corresponding to the third type of mouthfeel according to the weight information and the type information of the cooking food materials, wherein the third water volume threshold range is larger than or equal to the second preset water injection amount and smaller than the third preset water injection amount. The third type of mouthfeel corresponds to the optimal mouthfeel determined by the controller 10 according to the weight and the type of the cooking food material, and is the mouthfeel corresponding to the optimal water injection amount recommended by the controller 10, namely the obtained rice with the mouthfeel is moderate in hardness and suitable for most people to eat. It should be noted that the threshold range of water volume for the best taste sensation will be smaller relative to the threshold range of water volume for other taste sensation information.
And obtaining a fourth water volume threshold range corresponding to a fourth type of mouthfeel according to the weight information and the type information of the cooking food materials, wherein the fourth water volume threshold range is larger than or equal to a third preset water injection volume and smaller than a fourth preset water injection volume. The fourth category of cooking tastes corresponds to a softer taste, i.e. during cooking, when more water is added (not exceeding the maximum value), a softer taste rice will be obtained, and the water amount threshold range is suitable for the user who likes the softer taste.
And obtaining a fifth water amount threshold range corresponding to the fifth type of mouthfeel according to the weight information and the type information of the cooking food materials, wherein the fifth water amount threshold range is larger than or equal to a fourth preset water injection amount. The fifth type of texture corresponds to a texture corresponding to a food that cannot be normally enjoyed by the cooked food material, and in the case of rice cooking, the fifth type of texture is a "porridge" texture. When the amount of water injected by the user during cooking is within the range of the fifth water amount threshold value, the finally obtained rice is porridge, and the eating mouthfeel is seriously influenced. It should be noted that the first, second, third and fourth preset water injection amounts are water injection amount values whose numerical values are gradually increased. It can be understood that, when different cooking operations are performed according to the weight information and the type information of the cooking food materials, the water injection amount form control operation can be performed according to the above method, and the difference is only that the water amounts corresponding to the respective water amount threshold ranges are not consistent, or the number of the water amount threshold ranges is not consistent. For example, when the water amount threshold range consistent with the above amount is set for cooking porridge, the first preset water injection amount, the second preset water injection amount, the third preset water injection amount and the fourth preset water injection amount are only required to be changed.
In one embodiment, the display device 20 is a projection device. Specifically, when the water amount information is within a first water amount threshold range, a first color display control signal corresponding to the water amount information is obtained and sent to the projection device. The first color display control signal is used for controlling the projection device to project a first color. The first color display control signal is a control signal matched with the first type of taste, and the control signal can control the projection device to display an image or an indication line of a corresponding color (namely the first color). In other words, in the embodiment, after different water volume information is injected, the corresponding cooking taste type is informed to the user through the display signals with different colors, so that the user can conveniently inject water with corresponding volume according to own taste. It should be noted that in other embodiments, the user may be informed of the corresponding mouth feel types of different water amounts through other manners, for example, different images are displayed to inform the user of the corresponding mouth feel types according to the amount of water injected by the user.
It can be understood that after the water injection amount display function is turned on, and cooking materials are added to the cooking appliance, when the user does not inject water, the corresponding water amount information is zero and is also within the first water amount threshold range, at this time, the controller 10 similarly sends a first color display control signal to the projection device to control the projection device to project an image or an indication line of the first color. The color information displayed corresponding to the first color display control signal is not unique, and can be specifically set by a user in a self-defining manner in the actual operation process. For example, in one embodiment, the color information corresponding to the first color display control signal is red, that is, when the first color display control signal is received, the projection device displays a red image or an indication line.
And when the water amount information is within the second water amount threshold range, obtaining a second color display control signal corresponding to the water amount information and sending the second color display control signal to the projection device. The second color display control signal is used for controlling the projection device to project a second color. Similar to the water amount information in the first preset water amount preset range, the second color display control signal is a control signal matched with the second type of taste, and the control signal can control the projection device to display an image or an indication line of a corresponding color (namely, the second color). Similarly, the color information displayed corresponding to the second color display control signal is not unique, and can be specifically set by a user in a self-defining manner in the actual operation process. For example, in one embodiment, the color information corresponding to the second color display control signal is orange, that is, when the second color display control signal is received, the projection device displays an orange image or an indicator line.
Further, in one embodiment, when the water amount information is within the second water amount threshold range, the second color display control signal gradually decreases as the water amount information gradually approaches the second preset water injection amount, so that the second color projected by the projection device gradually becomes lighter. In this embodiment, when the amount of water injected is within the second water threshold range, the second color display control signal sent by the controller 10 to the projection device gradually decreases as the amount of water injected increases, and the second color of the image or the indication line projected by the corresponding projection device also gradually decreases. Taking rice as an example, when the color gradually becomes lighter, it is indicated that the hard taste of the corresponding rice is gradually weakened (i.e. the taste is gradually softened) after the cooking is finished. That is, in the present embodiment, by the gradual fade display of the color, the user can select different levels of the hard feeling, and the operation reliability is further enhanced.
And when the water amount information is within the third water amount threshold range, obtaining a third color display control signal corresponding to the water amount information and sending the third color display control signal to the projection device. The third color display control signal is used for controlling the projection device to project a third color. Similar to the water amount information in the first preset water amount preset range, the third color display control signal is a control signal matched with the third type of taste, and the control signal can control the projection device to display an image or an indication line of a corresponding color (namely, the third color). Similarly, the color information displayed corresponding to the third color display control signal is not unique, and can be specifically set by a user in a self-defining manner in the actual operation process. For example, in one embodiment, the color information corresponding to the third color display control signal is green, that is, when the third color display control signal is received, the projection device displays a green image or an indication line.
And when the water amount information is within the range of the fourth water amount threshold value, obtaining a fourth color display control signal corresponding to the water amount information and sending the fourth color display control signal to the projection device. The fourth color display control signal is used for controlling the projection device to project a fourth color. Similar to the water amount information in the first preset water amount preset range, the fourth color display control signal is a control signal matched with the fourth type of taste, and the control signal can control the projection device to display an image or an indication line of a corresponding color (namely, the fourth color). Similarly, the color information displayed corresponding to the fourth color display control signal is not unique, and can be specifically set by a user in a self-defining manner in the actual operation process. For example, in one embodiment, the color information corresponding to the fourth color display control signal is blue, that is, when the fourth color display control signal is received, the projection device displays a blue image or an indication line.
Further, in one embodiment, when the water amount information is within the fourth water amount threshold range, the fourth color display control signal gradually increases as the water amount information gradually approaches the fourth preset water injection amount, so that the fourth color projected by the projection device gradually deepens. In this embodiment, when the amount of water injected is within the fourth threshold range, the fourth color display control signal sent by the controller 10 to the projection apparatus is gradually increased along with the increase of the amount of water injected, and the fourth color of the image or the indication line projected by the corresponding projection apparatus is gradually deepened. Taking cooked rice as an example, when the color gradually deepens, the soft mouthfeel of the corresponding cooked rice is gradually enhanced after the cooking is finished (namely, the mouthfeel is gradually softened). That is, in the present embodiment, by gradually deepening the display of the color, the user can also select different soft feeling levels, and the operation reliability is higher.
And when the water amount information is within the range of the fifth water amount threshold value, obtaining a fifth color display control signal corresponding to the water amount information and sending the fifth color display control signal to the projection device. The fifth color display control signal is used for controlling the projection device to project a fifth color. Similar to the water amount information in the first preset water amount preset range, the fifth color display control signal is a control signal matched with the fifth type of taste, and the control signal controls the projection device to display an image or an indication line of a corresponding color (namely, a fifth color). Similarly, the color information displayed corresponding to the fifth color display control signal is not unique, and may be specifically set by a user in a self-defined manner in an actual operation process. For example, in one embodiment, the color information corresponding to the fifth color display control signal is red, that is, when the fifth color display control signal is received, the projection device displays a red image or an indication line, and the corresponding first color and the corresponding fifth color are the same color.
It should be noted that, in one embodiment, the colors projected by the projection device controlled by the first color display control signal, the second color display control signal, the third color display control signal, the fourth color display control signal and the fifth color display control signal may be different colors from each other. In other embodiments, the colors displayed by the first color display control signal and the second color display control signal may be the same color, and may be different from the colors displayed by the second color display control signal, the third color display control signal, and the fourth color display control signal, similar to the above.
Referring to fig. 3, for facilitating understanding of the projection operation of the projection apparatus of the present application, the following description is provided with reference to specific embodiments. The projection of the projection device is a wavy indication line, the colors displayed by the first color display control signal and the fifth color display control signal are consistent and are red, and the colors displayed by the second color display control signal, the third color display control signal and the fourth color display control signal are orange, green and blue respectively. When a user starts the water injection quantity display function and the cooking food is added into the cooking cavity, the projection device can directly project red wavy indication lines (the water injection quantity is 0 at the moment, is smaller than a first preset water injection quantity and is positioned in a first water quantity threshold range). When a user gradually injects water, the controller 10 acquires water amount information in real time and performs comparative analysis with the first preset water injection amount, and when the water injection amount reaches the first preset water injection amount (namely, is greater than or equal to the first preset water injection amount), the controller 10 controls the projection device to project an orange wavy indication line; if the water injection amount is still less than the first preset water injection amount, the controller 10 controls the projection device to keep projecting the red wavy indication line. When the water injection amount is gradually increased, the controller 10 sequentially performs contrastive analysis with the second preset water injection amount, the third preset water injection amount and the fourth preset water injection amount according to the water amount information acquired in real time, and the first water injection amount is similar to the first water injection amount in the previous process, which is not repeated herein. It can be understood that if the user is always filling water, the projection device will sequentially display the red wavy indication line, the orange wavy indication line, the green wavy indication line, the blue wavy indication line and the red wavy indication line, and finally stop at the red wavy indication line. When the user stops filling water, the corresponding water amount information is located in which section, and the corresponding projection device keeps displaying the wave indicating line with the corresponding color.
Referring to fig. 4, in an embodiment, the water filling amount status display control system further includes a visual recognition device 30, and the visual recognition device 30 is connected to the controller 10 (not shown). The visual recognition device 30 is configured to perform visual recognition processing on the top surface formed by the stacked cooking food materials, obtain parameter information of the cooking food materials, and send the parameter information to the controller 10.
Specifically, the visual recognition device 30 is an image processing device having functions of image acquisition, image feature extraction, image feature comparison analysis, and the like, and for facilitating understanding of the processing flow of the visual recognition device 30, the following explanation will be given with reference to the cooking food as rice. When cooking ingredients are added to the cooking appliance, the visual recognition device 30 can collect images of a certain area of the top surface formed when rice is accumulated in the cooking cavity. The visual recognition device 30 extracts a plurality of completed rice grain shapes from the image corresponding to the region, then corrects the data corresponding to a plurality of complete rice grain shapes one by one (mainly corrects the data corresponding to the edge shape of rice grains), and finally obtains the value data corresponding to each parameter of a rice grain shape after correction, that is, the data corresponding to a plurality of rice grain shapes are subjected to comprehensive contrastive analysis to obtain mean value data (namely cooking material parameter information) representing each parameter of a rice grain of the rice type. Then, the corresponding mean value data is transmitted to the controller 10 to be matched and analyzed with preset parameter information, and finally, which rice the mean value data of each parameter belongs to is obtained, that is, the type information of the cooking food material is obtained.
Referring to fig. 4, in an embodiment, the water injection state display control system further includes a lifting device 40, the lifting device 40 is connected to the controller 10 (not shown), and the visual recognition device 30 and the display device 20 are disposed on the lifting device 40.
Specifically, the lifting device 40 is configured to lift the visual recognition device 30 and the display device 20 to a corresponding position of the cooking cavity when the water injection amount display function is turned on, so that the visual recognition device 30 can perform visual recognition processing on a top surface formed by stacking the cooking food materials. After the user inputs the start instruction, the lifting device 40 will start to move, and the visual recognition device 30 and the display device 20 are lifted to the corresponding positions through the lifting device 40, so that the visual recognition device 30 can acquire the image information of the top surface formed by the stacked cooking food materials in the cooking cavity. And simultaneously, the display device 20 can project images or indication lines with different colors on the inner surface or the bottom center position of the cooking cavity. It can be understood that, in one embodiment, when the water filling amount display function is not activated, the lifting device 40, the display device 20 and the visual recognition device 30 are received in the gap between the cooking cavity and the cooking appliance body and located at the end of the cooking cavity opposite to the open end (i.e. the bottom of the cooking cavity), and after the water filling amount display function is activated, the lifting device 40 is lifted to the open end of the cooking cavity, so that the acquisition of the image information and the corresponding display operation are realized.
Referring to fig. 4, in an embodiment, the water injection state display control system further includes a weight detection device 50, and the weight detection device 50 is connected to the controller 10 (not shown).
Specifically, the weight detecting means 50 is used for detecting the weight information of the cooking food material and the water amount information in the cooking cavity, and the weight detecting means 50 is used for detecting the weight information of the cooking food material and the water amount information in the cooking cavity. When the cooking cavity has been filled with the cooking food material and the user has input a corresponding opening command, the controller 10 will perform a water filling amount display operation. Firstly, the weight data is collected by the weight detection device 50 and sent to the controller 10, and the controller 10 subtracts the preset weight parameter of the cooking appliance according to the weight data, so as to obtain the weight information of the cooking food. The preset weight parameter of the cooking appliance is not unique, because only the weight of the articles inside the cooking cavity changes during the cooking process of the cooking appliance, and the weight of the whole cooking appliance is fixed and unchanged. Therefore, when the weight detection device 50 acquires the weight change of the cooking cavity, the corresponding preset weight parameter of the cooking appliance is the body weight of the cooking cavity; when the weight detection device 50 collects weight data of the whole cooking appliance, the corresponding preset cooking appliance weight parameter is the body weight of the whole cooking appliance.
It should be noted that the location of the weight detecting means 50 is not exclusive, and in one embodiment, the weight detecting means 50 may be located at the bottom of the cooking cavity such that the weight of the entire cooking cavity acts on the weight detecting means 50 to detect the weight change of the cooking cavity. In another embodiment, it is also possible to arrange the weight detecting device 50 at the bottom of the entire cooking appliance such that the weight of the entire cooking appliance acts on the weight detecting device 50 to detect the weight change of the cooking appliance. For example, the bottom of the supporting leg of the cooking appliance. Further, in one embodiment, the weight detecting device 50 is a weight sensor.
In one embodiment, the controller 10 is a Micro Controller Unit (MCU). The micro control unit, also called a microcomputer or a single chip, is a chip-level computer formed by appropriately reducing the frequency and specification of a central processing unit and integrating peripheral interfaces such as a memory (memory), a counter (Timer), a USB, a/D conversion, a UART, PLC, DMA, and the like, and even an LCD driving circuit, on a single chip. The control operation is realized through the MCU, and the method has the advantages of easiness in realization and high control reliability.
In the water injection amount state display control system of the cooking appliance, the controller 10 first obtains the weight information and the type information of the cooking materials contained in the cooking cavity. And then analyzing according to the obtained weight information and the type information of the cooking food materials, so as to obtain the water volume threshold value range corresponding to different cooking tastes under the current cooking food materials and the corresponding weight. When a user fills water into the cooking cavity, the controller 10 can acquire the added water amount information in real time and then determine in which water amount threshold range the water amount information is located. When the water amount information is in different water amount threshold ranges, the controller 10 outputs different control signals to control the display device 20 to display different information, so as to inform the user what taste the cooking food material will get after cooking is completed when cooking under the current water amount information. Through the scheme, the user can control the added water quantity according to the required taste of the user, and the cooking food is not limited by the types of cooking food materials, so that the food with the expected cooking taste consistent with the expected cooking taste of the user can be obtained finally. Compared with the traditional electric cooker water injection method, the method has the advantage of strong operation reliability.
Referring to fig. 5, a cooking appliance includes a cooking appliance body 70 and the above-mentioned water injection state display control system.
Specifically, the manner of acquiring the weight information of the cooking material and the type information of the cooking material is not unique. In the cooking process, after the user obtains the weight information of the cooking material through measurement by the external device, the weight information of the cooking material and the type information of the cooking material may be manually input to the controller 10. In other embodiments, the detection may be performed by a corresponding device disposed on the cooking appliance, for example, in one embodiment, the cooking appliance is provided with the weight detection device 50 to detect a change of weight data of the cooking appliance in real time, that is, to obtain weight information corresponding to the cooking food material contained in the cooking cavity, and the weight detection device 50 may also perform real-time detection of the amount of water added in the cooking cavity. Meanwhile, the cooking appliance is further provided with a visual recognition device 30, and the types of cooking food materials added into the cooking cavity are obtained through image acquisition and image recognition technologies. In order to facilitate understanding of the various embodiments of the present application, the following explanation is given of the collection of the cooking material content information by the weight detecting device 50 and the identification of the cooking material type information by the visual recognition device 30.
For the same cooking food material, under different weights, the required water amount is inconsistent in order to obtain the same cooking taste; likewise, for different types of cooking ingredients, the amount of water required is not consistent in order to obtain the same or similar cooking mouthfeel at the same weight. That is, in the cooking process, when the weight and the kind of the cooking materials are consistent, the cooking taste of the cooking materials is mainly determined by the injected water amount. It should be noted that in one embodiment, the controller 10 is pre-programmed with expansion rate curves for different types of cooking ingredients, the expansion rate curves representing water absorption information for the different cooking ingredients. And analyzing and processing according to the water absorption information of different cooking food materials and the weight information of the cooking food materials, so as to obtain the water absorption and expansion conditions of all the cooking food materials in the cooking cavity. In the cooking process of the food materials, different mouthfeel information can be obtained after different water amounts absorbing water are cooked, so that the finally obtained cooking mouthfeel type of the food can be judged according to the amount of the water amount added into the cooking food materials. The user can intuitively obtain the finally obtained cooking taste under the water injection state through the information of the injected water amount.
The control signal is used for controlling the display device 20 to display a corresponding signal so as to inform a user of the cooking taste corresponding to the current water injection amount. A display device 20 is provided in the cooking appliance, and when the controller 10 detects that the amount of water injected into the cooking cavity by the user is changed according to the weight detection device 50, the display device 20 can display different information according to the change of the amount of water in real time. Specifically, the color of the emitted indication line or image can be changed, and the user can intuitively obtain the cooking taste matched with the color according to different colors. It will be appreciated that when the user stops adding water, the color projected by the display device 20 will not continue to change, and will remain the color corresponding to the water amount information of the currently injected water until the user turns off the water injection amount display function, and the indication of the color will disappear.
Further, in one embodiment, the cooking appliance is an electric rice cooker. That is, the electric cooker is provided with a display device 20 and the like, when cooking rice or porridge, the weight information and the type information (including ivory rice, pearl rice and the like) of the rice in the inner container of the electric cooker are firstly obtained according to the controller 10; then, obtaining water quantity threshold ranges corresponding to different cooking tastes according to the weight information and the type information of the rice; and finally, when the user injects water into the inner container, performing comparative analysis according to the water amount information acquired in real time and each water amount threshold range to obtain a control signal corresponding to the water amount information, and sending the control signal to the display device 20. The display device 20 projects images or indication lines with different colors according to the control signal corresponding to the water amount information to inform the user of the taste type of the rice to be obtained under the current water amount information.
In the cooking appliance, the controller 10 first obtains the weight information and the type information of the cooking materials contained in the cooking cavity. And then analyzing according to the obtained weight information and the type information of the cooking food materials, so as to obtain the water volume threshold value range corresponding to different cooking tastes under the current cooking food materials and the corresponding weight. When a user fills water into the cooking cavity, the controller 10 can acquire the added water amount information in real time and then determine in which water amount threshold range the water amount information is located. When the water amount information is in different water amount threshold ranges, the controller 10 outputs different control signals to control the display device 20 to display different information, so as to inform the user what taste the cooking food material will get after cooking is completed when cooking under the current water amount information.
