Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cooking appliances, and particularly relates to a method for displaying the countdown of the rice function for a cooking appliance. Background Art
[0002] As an essential cooking appliance, rice cookers are commonly found in the kitchens of people across the country. And as a basic function of the rice cooker, the rice function is one of the most frequently used functions by users.
[0003] Currently, the functions of existing rice cookers and other cooking appliances on the market can be divided into two categories according to the type of countdown display: rice category and countdown category. For the functions of the countdown type, the required working duration is displayed when the function is selected, and the working duration can be adjusted. For example, when the porridge cooking function is selected, the display module may show 1 hour and 30 minutes, indicating that this function will complete the work one hour and thirty minutes after startup. However, for the rice category functions, the cooking time is rarely clearly displayed. Generally, a running light is first displayed, and then a countdown is displayed when it reaches the rice simmering stage. Such a display method makes it impossible for users to accurately judge the cooking duration due to differences in the amount of rice, water, and machine power. Then, in the cooking scenario, due to the problem of duration estimation, there may be a situation where other dishes are already cooked but the rice is not yet cooked; or the rice is cooked but other dishes are not yet cooked, and the heat preservation will cause the flavors of the rice and dishes to be lost, which cannot allow users to experience the best taste of the rice or other dishes and affects the user experience.
[0004] Therefore, the existing technology needs to be further improved and enhanced. Summary of the Invention
[0005] The present application provides a method for displaying the countdown of the rice function for a cooking appliance to solve at least one of the above technical problems.
[0006] The technical solution adopted by the present application is as follows:
[0007] A method for displaying the countdown of the rice function of a rice cooker, the rice cooker includes a display board and a heating system respectively connected to a control system, and the method for displaying the countdown of the rice function includes:
[0008] The first stage: when cooking starts, control the display board to display a countdown at a fixed first step length;
[0009] The second stage: the control system adjusts the step length according to the countdown display duration of the display board and the expected remaining cooking duration, and controls the display board to display a countdown at the adjusted second step length;
[0010] The third stage: control the display board to display a countdown at a fixed third step length according to the display board countdown until the countdown reaches zero.
[0011] The rice function countdown display method for cooking appliances in this application also has the following additional technical features:
[0012] As an optional implementation, it further includes: in the second stage: the control system determines the amount of rice according to the working conditions of the heating system, adjusts the countdown display duration of the display board according to the amount of rice, and controls the display board to output a signal for characterizing the change in the countdown duration.
[0013] As an optional implementation, it further includes: in the second stage: the control system adjusts the heating power according to the countdown display duration of the display board and the estimated remaining cooking duration.
[0014] As an optional implementation, the rice function includes a water absorption stage, a temperature rising stage, a boiling stage, a temperature flushing stage, and a rice simmering stage; the water absorption stage corresponds to the first stage; the temperature rising stage, the boiling stage, and the temperature flushing stage correspond to the second stage; the rice simmering stage corresponds to the third stage.
[0015] As an optional implementation, in the temperature rising stage, when the continuous duration exceeds the first duration, the control system starts step size adjustment.
[0016] As an optional implementation, in the boiling stage, the countdown display duration of the display board is adjusted according to the amount of rice, the continuous duration of the boiling stage is allocated according to the adjusted countdown display duration; the heating power is adjusted according to the continuous duration of the boiling stage and the amount of rice; step size adjustment is started according to the amount of rice, the heating power, and the adjusted countdown display duration.
[0017] As an optional implementation, in the temperature flushing stage, when the continuous duration exceeds the second duration, the control system starts step size adjustment.
[0018] As an optional implementation, the third step size is the same as the adjusted step size in the temperature flushing stage; or, the third step size is the same as the first step size.
[0019] As an optional implementation, the minimum display time unit of the display board is minutes, and the first step size is 1 min.
[0020] As an optional implementation, when the control system adjusts the step size according to the countdown display duration of the display board and the estimated remaining cooking duration, it includes: calculating a step size adjustment coefficient according to the countdown display duration and the estimated remaining cooking duration; calculating the second step size according to the step size adjustment coefficient.
[0021] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows:
[0022] 1. For the rice function countdown display method for cooking appliances provided by this application, when the cooking starts in the first stage, the display board performs countdown display at a fixed step length. In the second stage, the control system estimates the remaining cooking duration required, and adjusts the step length of the countdown displayed on the display board according to the remaining cooking duration required and the remaining duration of the countdown display, so as to make the remaining cooking duration displayed by the countdown correspond to the actual remaining cooking duration as much as possible. This enables the user to obtain the remaining cooking duration of the rice through the countdown display, and can arrange the cooking time of other dishes or the dining time more accurately according to the remaining cooking duration of the rice, and can avoid as much as possible the situation where other dishes are already cooked but the rice is not yet cooked, and the situation where other dishes are not yet cooked after the rice is cooked, and the heat preservation will cause the loss of the flavor of the rice and the dishes, and the problem that the user cannot experience the best taste of the rice or other dishes, which can greatly improve the user experience, and improve the practicality and intelligence level of the rice cooker.
[0023] 2. As an optional implementation manner, in the second stage: the control system determines the amount of rice according to the working condition of the heating system, adjusts the countdown display duration of the display board according to the amount of rice, and controls the display board to output a signal for characterizing the change of the countdown duration. That is, after performing countdown display at a fixed step length for a certain duration, the control system can judge the amount of rice in the rice cooker according to the working condition of the heating system, and re-determine the estimated remaining cooking duration of the rice cooking according to the amount of rice in the rice cooker. At this time, there may be a large difference between the estimated remaining cooking duration and the countdown display duration. Then, the step length to be adjusted is also quite different from the fixed step length used before. Therefore, there may still be a large gap between the countdown display duration and the estimated remaining cooking duration after the step length is adjusted. At this time, the countdown display duration of the display board can be directly adjusted to be close to or equal to the estimated remaining cooking duration, and the user is reminded by controlling the display board to output a signal for characterizing the change of the countdown duration; this can further improve the display accuracy of the countdown display duration, and at the same time can further avoid the situation where other dishes are already cooked but the rice is not yet cooked, and the situation where other dishes are not yet cooked after the rice is cooked, and the heat preservation will cause the loss of the flavor of the rice and the dishes, and further improve the user experience, and improve the practicality and intelligence level of the rice cooker.
[0024] 3. As an alternative implementation, in the second stage: the control system can also adjust the heating power according to the countdown display duration of the display panel and the estimated remaining cooking duration. When the difference between the estimated remaining cooking duration and the countdown display duration is large, and the step size to be adjusted is also significantly different from the fixed step size used previously, so there may still be a large gap between the countdown display duration and the estimated remaining cooking duration after the step size adjustment. By adjusting the heating power of the heating system to narrow the duration gap between the estimated remaining cooking duration and the countdown display duration, the display accuracy of the countdown display duration can be further improved, the user experience can be further enhanced, and the practicality and intelligence level of the rice cooker can be improved.
[0025] 4. As an alternative implementation, the rice function includes a water absorption stage, a temperature rising stage, a boiling stage, a temperature flushing stage, and a rice stewing stage; the water absorption stage corresponds to the first stage; the temperature rising stage, the boiling stage, and the temperature flushing stage correspond to the second stage; the rice stewing stage corresponds to the third stage. Adjusting the step size of the countdown display duration is dispersed throughout the entire rice cooking process, making the entire adjustment process stable without jumps or waiting phenomena, and further improving the user experience.

[0029] Figure 2 It is a flowchart of another method for displaying the countdown of the rice function for a cooking appliance provided by an embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0030] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.
[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.
[0032] Referring to the background technology, the functions of existing cooking appliances such as rice cookers on the market can be classified into two categories according to the countdown display type: rice type and countdown type. The function of the countdown type displays the required working duration when the function is selected, and the working duration can be adjusted. For example, when the porridge cooking function is selected, the display module may display 1 hour and 30 minutes, indicating that this function will complete the work one hour and thirty minutes after startup. The rice type function rarely clearly displays the cooking time. Generally, it first displays a marquee and then displays the countdown when it reaches the rice simmering stage. Such a display method makes it impossible for users to accurately judge the cooking duration due to differences in the amount of rice, water, and machine power. Then, in the cooking scenario, due to the problem of duration estimation, there may be a situation where other dishes are already cooked but the rice is not yet cooked; or the rice is cooked but other dishes are not yet cooked, and keeping warm will cause the flavors of the rice and dishes to be lost, and users cannot experience the best taste of the rice or other dishes, affecting the user experience.
[0033] In response to the above technical problems, as Figure 1 shown, this application provides a method for displaying the countdown of the rice function of a rice cooker. The rice cooker includes a display board and a heating system respectively connected to a control system. The method for displaying the countdown of the rice function includes:
[0034] The first stage: When cooking starts, control the display board to display the countdown at a fixed first step length;
[0035] Second stage: The control system adjusts the step length according to the countdown display duration of the display board and the estimated remaining cooking duration, and controls the display board to perform countdown display with the adjusted second step length.
[0036] Third stage: According to the countdown of the display board, control the display board to perform countdown display with a fixed third step length until the countdown reaches zero.
[0037] Specifically, at the beginning of the first stage of cooking, the display board performs countdown display according to a fixed step length. In the second stage, the control system estimates the remaining cooking duration, and adjusts the step length of the countdown displayed on the display board according to the remaining cooking duration and the remaining duration of the countdown display, so as to make the remaining cooking duration of the countdown display correspond to the actual remaining cooking duration as much as possible. This enables the user to obtain the remaining cooking duration of the rice through the countdown display, and can arrange the cooking time of other dishes or the dining time more accurately according to the remaining cooking duration of the rice, and can avoid as much as possible the situation where other dishes are already cooked but the rice is not yet cooked, and the situation where other dishes are not yet cooked after the rice is cooked, and the loss of the flavor of the rice and the dishes due to heat preservation, so that the user cannot experience the best taste of the rice or other dishes, and can greatly improve the user experience, the practicality and the intelligent level of the rice cooker.
[0038] It should be noted that this application does not limit the corresponding relationship between the first stage, the second stage and the third stage and the specific cooking stages in the rice cooking process, so it does not limit the specific cooking method of the rice either. The specific distribution methods of the first stage, the second stage and the third stage can be selected according to the actual rice cooking method.
[0039] In addition, this application does not limit the specific values and quantitative relationships of the fixed first step length and the fixed third step length. As an optional implementation manner, when the minimum display time unit of the display board is minutes, the first step length can be 1 min. Similarly, when the minimum display time unit of the display board is seconds, the first step length can be 1 s. Setting the first step length as the time standard step length can make the remaining cooking duration of the countdown display correspond to the actual remaining cooking duration as much as possible. Similarly, as an optional implementation manner, the third step length can be the same as the step length adjusted in the preheating stage, or the same as the first step length.
[0040] As an optional implementation manner, it further includes: in the second stage, the control system determines the rice quantity according to the working condition of the heating system, adjusts the countdown display duration of the display board according to the rice quantity, and controls the display board to output a signal for characterizing the change of the countdown duration.
[0041] Specifically, in the second stage: the control system determines the amount of rice according to the working condition of the heating system, adjusts the countdown display duration of the display board according to the amount of rice, and controls the display board to output a signal for characterizing the change in the countdown duration. That is, after counting down for a certain duration with a fixed step length, the control system can judge the amount of rice in the rice cooker according to the working condition of the heating system, and re-determine the estimated remaining cooking duration of the rice cooking according to the amount of rice in the rice cooker. At this time, there may be a large difference between the estimated remaining cooking duration and the countdown display duration. Then, the step length to be adjusted is also quite different from the fixed step length used before. Therefore, there may still be a large gap between the countdown display duration and the estimated remaining cooking duration after the step length is adjusted. At this time, the countdown display duration of the display board can be directly adjusted to be close to or equal to the estimated remaining cooking duration, and the user is reminded by controlling the display board to output a signal for characterizing the change in the countdown duration; it can further improve the display accuracy of the countdown display duration, and at the same time can further avoid the situation that other dishes are already cooked but the rice is not cooked yet, and the situation that other dishes are not cooked yet after the rice is cooked, and the heat preservation will cause the loss of the flavor of the rice and the dishes, further improving the user experience and the practicality and intelligence of the rice cooker.
[0042] Among them, the present application does not limit the adjustment method of the countdown display duration. Optionally, a maximum adjustment threshold can be set so that the adjustment value of the countdown display duration does not exceed the maximum adjustment threshold to avoid the situation of user dissatisfaction that may be caused by too large an adjustment value; if the countdown display duration still has a large gap with the estimated remaining cooking duration when the adjustment value is equal to the maximum adjustment threshold, the methods such as step length adjustment and power adjustment are combined to narrow the gap between the countdown display duration and the estimated remaining cooking duration.
[0043] At the same time, the present application does not limit the specific method for the display board to output a signal for characterizing the change in the countdown duration. It can be set that there are specific symbols for indicating the change in the countdown duration, and the specific symbol content is output to the user in advance through the instruction manual or video explanation. When the countdown duration changes, the specific symbols are output in real time through the digital tube to convey the information that the countdown duration has changed to the user. Or cooking appliances such as rice cookers are provided with intelligent display screens, and text information similar to "the countdown duration has changed" can be directly output through the screen, and a prompt sound can also be accompanied.
[0044] As an optional implementation manner, it further includes: in the second stage: the control system adjusts the heating power according to the countdown display duration of the display board and the estimated remaining cooking duration.
[0045] Specifically, when there is a large difference between the predicted remaining cooking duration and the countdown display duration, and the step size to be adjusted is also significantly different from the fixed step size used previously, so there may still be a large gap between the countdown display duration and the predicted remaining cooking duration after the step size adjustment. By adjusting the heating power of the heating system to narrow the duration gap between the predicted remaining cooking duration and the countdown display duration, the display accuracy of the countdown display duration can be further improved, the user experience can be enhanced, and the practicality and intelligence level of the rice cooker can be improved.
[0046] It should be noted that the predicted remaining cooking duration can be adjusted only by adjusting the step size and the heating power, or only by adjusting the step size and adjusting the countdown display duration of the display board according to the rice quantity to further achieve the effect of narrowing the duration gap between the predicted remaining cooking duration and the countdown display duration. It can also be adjusted by a combination of multiple methods. For example, adjust the countdown display duration of the display board to be close to the predicted remaining cooking duration, then adjust the heating power according to the countdown display duration of the display board and the predicted remaining cooking duration, and finally adjust the step size to make the countdown display of the display board more accurate.
[0047] In addition, the present application does not limit the specific method for the control system to determine the rice quantity. It can be judged according to the relationship between the heating temperature corresponding to the specific heating duration, or it can be judged according to the duration of the specific cooking stage of the rice.
[0048] For example, as Figure 2 shown, as an optional implementation manner, when the rice function includes a water absorption stage, a temperature rising stage, a boiling stage, a temperature flushing stage, and a rice stewing stage, the water absorption stage can correspond to the first stage; the temperature rising stage, the boiling stage, and the temperature flushing stage correspond to the second stage; the rice stewing stage corresponds to the third stage.
[0049] Disperse the adjustment of the step size of the countdown display duration throughout the rice cooking process, making the entire adjustment process stable without jumps or waiting phenomena, and further improving the user experience.
[0050] As an optional implementation manner, in the temperature rising stage, when the continuous duration exceeds the first duration, the control system starts to adjust the step size.
[0051] Specifically, the first duration is not limited, and it can be limited according to the specific rice quantity and the model of the rice cooker. From the end of the water absorption stage to the end of the temperature rising stage, at this time, the control system can determine the temperature rise according to the temperature of the rice in the cooking utensil. It can be determined that the temperature rising stage ends when the measured temperature is greater than 72 degrees, and it can be set that when the working time in the temperature rising stage exceeds 6 minutes, the step size adjustment is started.
[0052] As an alternative implementation, during the boiling stage, the countdown display duration of the display panel is adjusted according to the amount of rice, and the duration of the boiling stage is allocated according to the adjusted countdown display duration; the heating power is adjusted according to the duration of the boiling stage and the amount of rice; step size adjustment is started according to the amount of rice, the heating power, and the adjusted countdown display duration.
[0053] Specifically, by way of example, from the end of the temperature rise stage to the end of the boiling stage, after the end of the temperature rise stage, the control system can determine the amount of rice according to operating conditions such as the working duration of the temperature rise stage. After obtaining the amount of rice, the control system can adjust the countdown display duration and notify the user that the countdown display duration has changed. At this time, step size adjustment can be started again to adjust the second step size. At the same time, when entering the boiling stage, the control system can allocate the duration of the boiling stage according to the countdown display duration and adjust the heating power of the boiling stage. The end of the boiling stage can be determined according to the temperature of the rice in the cooking appliance and the duration of the boiling stage. When the measured temperature is greater than 92 degrees or the duration of the boiling stage is greater than the allocated duration, it is determined that the boiling stage has ended.
[0054] As an alternative implementation, during the temperature boosting stage, when the duration exceeds the second duration, the control system starts step size adjustment.
[0055] Specifically, by way of example, from the end of the boiling stage to the end of the temperature boosting stage, the duration of the temperature boosting stage can also be allocated according to the amount of rice in this stage, and the heating power is adjusted. The end of this stage can also be determined according to the temperature of the rice in the cooking appliance. When the measured temperature value is greater than the temperature boosting set temperature value or the working duration is greater than the allocated duration, it is considered that the temperature boosting stage has ended, and step size adjustment can be started when the duration of the temperature boosting stage is greater than 3 minutes to adjust the countdown step size.
[0056] As an alternative implementation, the control system adjusts the step size according to the countdown display duration of the display panel and the estimated remaining cooking duration, including: calculating a step size adjustment coefficient according to the countdown display duration and the estimated remaining cooking duration; calculating a second step size according to the step size adjustment coefficient.
[0057] Specifically, the target cooking duration of the rice function is set as t1, the working duration of the rice function is set as t2, the countdown display duration during the cooking process is Td, and the estimated remaining cooking duration Ta = t1 - t2. Then, the step size adjustment coefficient λ = Ta ÷ Td can be obtained during the cooking process. The variable time step size Tad = λTs can be used for the countdown display between the water absorption stage and the rice stewing stage.

[0059] In the above embodiments of the present application, the descriptions of the respective embodiments have their own focuses. For the parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.

However, it is easy for those skilled in the art to understand that the protection scope of the present application is not limited to these specific embodiments. Without departing from the technical principle of the present application, those skilled in the art can split and combine the technical solutions in the above-mentioned respective embodiments, and can also make equivalent changes or substitutions to the relevant technical features.
