[0046] The core of the application is to provide a method, system, device, electric pressure cooker and storage medium for determining food type of electric pressure cooker, which can determine the food type of the food to be cooked, so as to adjust the cooking mode corresponding to the food type subsequently, thereby avoiding problems such as cooking failure that affect user experience.

[0047] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0048] Please refer to Figure 1 , Figure 1 A flowchart of a method for determining food type of an electric pressure cooker is provided in the present application. The control method comprises:

[0049] S1: controlling a heating module in the electric pressure cooker to work at a first preset working power;

[0050] To solve the problem that the electric pressure cooker in the prior art usually cooks the food to be cooked according to the cooking mode selected by the user, but the user sometimes selects the wrong cooking mode, resulting in the problem of soup spitting or undercooking of the electric pressure cooker, the present application controls the electric pressure cooker to automatically judge the food type of the food to be cooked. After determining the food type of the food to be cooked in the electric pressure cooker, it can be determined whether the cooking mode selected by the user matches the food to be cooked. When the cooking mode selected by the user does not match the food to be cooked, the working mode of the electric pressure cooker is adjusted.

[0051] Specifically, first, the heating module in the electric pressure cooker is controlled to work at a first preset working power. The specific value of the first preset working power is not particularly limited in the present application. The first preset working power can be set to more than sixty percent of the rated power of the electric pressure cooker, so as to speed up the efficiency of detecting the food type in the present application.

[0052] S2: when the pressure in the electric pressure cooker reaches a preset pressure range, controlling the heating module to stop working, and adding one to the number of pressure signal actions;

[0053] S3: determining whether the working time of the electric pressure cooker is greater than a preset detection time, wherein the preset detection time is less than the cooking setting time of the electric pressure cooker; if not, entering S1; if yes, entering S4;

[0054] When the heating module works at the first preset working power for a period of time, the pressure in the electric pressure cooker reaches a preset pressure range. The preset pressure range can be the pressure range corresponding to the cooking mode selected by the user. For example, when the user selects the low-pressure cooking mode, the preset pressure range is 35Kpa to 55Kpa, and when the user selects the high-pressure cooking mode, the preset pressure range is 65Kpa to 85Kpa.

[0055] The pressure signal action times are all added by one each time the pressure in the electric pressure cooker reaches the preset pressure range, wherein the pressure signal can be generated by a pressure detection module in the electric pressure cooker when detecting that the pressure in the electric pressure cooker reaches the preset pressure range, and then the pressure signal action times are added by one each time the application receives the pressure signal output by the pressure detection module.

[0056] The heating module is controlled to stop working when the pressure in the electric pressure cooker reaches the preset pressure range, so that the pressure in the electric pressure cooker gradually decreases, the heating module is started again and continues to work at the first preset power when the working time of the electric pressure cooker is not greater than the preset detection time, so that the pressure in the electric pressure cooker rises again, and the pressure signal action times are added by one when the pressure in the electric pressure cooker rises again to the preset pressure range, so that the application can determine the food type based on the pressure signal action times of the electric pressure cooker within the preset detection time. When the working time of the electric pressure cooker reaches the preset detection time, enter the subsequent step of determining the food type of the food to be cooked in the electric pressure cooker based on the pressure signal action times, and it should be noted that the preset detection time is less than the cooking setting time of the electric pressure cooker, and the cooking setting time refers to the total cooking time corresponding to the cooking mode selected by the user, that is, a time period is selected before the cooking of the electric pressure cooker is completed to determine the pressure signal action times of the electric pressure cooker in the time period.

[0057] S4: Determine the pressure signal action times of the electric pressure cooker within the preset detection time, and determine the food type of the food to be cooked in the electric pressure cooker according to the pressure signal action times.

[0058] Different types of food reach different temperatures under the same time and the same heating strategy, so the temperature inside the electric pressure cooker is also different, and because there is a certain proportional relationship between the temperature and the pressure in the electric pressure cooker, the pressure in the electric pressure cooker is also different. The application determines the food type of the food to be cooked based on the above principle according to the pressure signal action times of the electric pressure cooker within the preset detection time. The food type of the food to be cooked in the application can be juicy water food and less juicy water food, or other food types, and the classification standard of the pressure in the electric pressure cooker is different, which is not particularly limited by the application.

[0059] In summary, the application provides a method for determining food type of an electric pressure cooker. First, a heating module is controlled to heat the electric pressure cooker at a first preset working power. When the pressure in the electric pressure cooker reaches a preset pressure range, the heating control module stops working and the number of pressure signal actions is increased by one so as to determine the food type based on the number of pressure signal actions subsequently. When the working time of the electric pressure cooker does not reach a preset detection time, the heating module is continuously controlled to repeat the above steps until the working time reaches the preset detection time. The food type of the food to be cooked is determined based on the number of pressure signal actions of the electric pressure cooker within the preset detection time, so as to adjust the cooking mode corresponding to the food type, thereby avoiding problems such as cooking failure that affect user experience.

[0060] On the basis of the above embodiment,

[0061] As a preferred embodiment, the food type includes juicy water food and less juicy water food. After determining the food type of the food to be cooked in the electric pressure cooker, the method further includes:

[0062] When the food type is determined to be juicy water food, the heating module is controlled to work at a second preset working power until the electric pressure cooker meets a preset cooking end condition, and then the heating module is controlled to stop working.

[0063] When the food type is determined to be less juicy water food, the heating module is controlled to work at a third preset working power until the electric pressure cooker meets a preset cooking end condition, and then the heating module is controlled to stop working, wherein the third preset working power is less than the second preset working power.

[0064] In this embodiment, the food type specifically includes juicy water food and less juicy water food. It is considered that the requirements of the heating mode of the electric pressure cooker for the juicy water food and the less juicy water food are different. For example, when the electric pressure cooker is used to cook porridge or soup and other juicy water food with high water content, the temperature rising process of the electric pressure cooker is relatively slow, and therefore the electric pressure cooker needs to be controlled to work at a relatively high power. When the electric pressure cooker is used to cook steamed rice and other less juicy water food with low water content, the temperature rising process of the electric pressure cooker is relatively fast, and therefore the electric pressure cooker can be controlled to work at a relatively low power. Please refer to Figure 2 , Figure 2Another flow chart of the method for determining food type of an electric pressure cooker is provided in the present application, after the food type of the food to be cooked in the electric pressure cooker is determined, the electric pressure cooker is controlled to cook at different working powers for different food types. Specifically, when the food to be cooked is determined to be juicy water type food, the heating module is controlled to work at a second preset working power until the electric pressure cooker reaches a preset cooking end condition, and then the heating module is controlled to stop working; when the food to be cooked is determined to be less juicy water type food, the heating module is controlled to work at a third preset working power smaller than the second preset working power until the cooking is completed. It should be noted that the third preset working power is smaller than the second preset working power because the temperature rising speed of the juicy water type food and the less juicy water type food is different, and the temperature of the less juicy water type food rises faster when the heating module works at the same working power, so the heating module can select a lower working power to heat the food to be cooked.

[0065] The values of the second preset working power and the third preset working power are not particularly limited in the present application, and can be set according to actual conditions. In addition, considering that the first preset power is usually set to be relatively high in order to speed up the determination process of the food type, but the electric pressure cooker may cause the juice to overflow at the exhaust valve when cooking the juicy water type food at a too high power, the second preset working power in the present embodiment can be set to a value smaller than the first preset working power.

[0066] It should be noted that the juicy water type food and the less juicy water type food in the present application are determined according to the water content of the food to be cooked before the food is cooked using the electric pressure cooker. The water content is the ratio of the weight of water in the food to be cooked to the total weight of the food to be cooked. When the water content of the food to be cooked is greater than a preset dividing value, the food to be cooked is considered to be juicy water type food, and vice versa. The specific value of the preset dividing value is not particularly limited in the present application, and can be set according to the actual working performance of the electric pressure cooker. In actual application, the juicy water type food usually includes soup and porridge, and the less juicy water type food usually includes dry rice and casserole rice.

[0067] In addition, the preset cooking end condition is not particularly limited in the present application, and the preset cooking end condition can be that the cooking time of the electric pressure cooker reaches the cooking setting time and the temperature in the electric pressure cooker reaches the cooking setting temperature corresponding to the cooking mode selected by the user.

[0068] In summary, in the present embodiment, the heating module is controlled to work at different working powers for the juicy water type food and the less juicy water type food, which better guarantees the cooking effect of different types of food and further optimizes the cooking performance of the electric pressure cooker.

[0069] As a preferred embodiment, the food type of the food to be cooked in the electric pressure cooker is determined according to the number of times of pressure signal actions, comprising:

[0070] When the number of times of pressure signal actions is greater than a preset number threshold, the food type is determined to be a juicy water type food;

[0071] When the number of times of pressure signal actions is not greater than the preset number threshold, the food type is determined to be a less juicy water type food.

[0072] In the embodiment, the food type of the food to be cooked is determined according to the number of times of pressure signal actions, specifically, when the number of times of pressure signal actions is greater than a preset number threshold, the food type is determined to be a juicy water type food. Since the juicy water type food generates water vapor after being heated by the heating module working at a first preset working power, the pressure in the electric pressure cooker rises faster, so the number of times of reaching the preset pressure range in the same time is more. When the number of times of pressure signal actions is not greater than the preset number threshold, the food type is determined to be a less juicy water type food. Since the pressure in the electric pressure cooker rises slower when cooking the less juicy water type food under the condition that the heating module works at the first preset working power for the same time, the number of times of reaching the preset pressure range in the same time is relatively less. In summary, the above two types of food are distinguished based on the different principles of the influence of the juicy water type food and the less juicy water type food on the pressure in the electric pressure cooker in the embodiment, and the distinguishing method is simple and effective, further improving the performance of the electric pressure cooker.

[0073] As a preferred embodiment, after the number of times of pressure signal actions is added by one, further comprising:

[0074] determining whether the total working duration of the heating module from starting working to the current time reaches a cooking setting time;

[0075] if yes, controlling the electric pressure cooker to exhaust steam according to the preset steam exhaust strategy corresponding to the food type;

[0076] if no, entering the step of determining whether the working time of the electric pressure cooker is greater than a preset detection time.

[0077] It is considered that different types of food have different applicable steam exhaust strategies. For example, if the steam exhaust valve of the electric pressure cooker is continuously opened until the steam exhaust is completed when cooking porridge with the electric pressure cooker, the porridge in the electric pressure cooker may overflow through the steam exhaust valve, which may cause the electric pressure cooker to be filled with water or cause the user to be scalded, etc. Therefore, when cooking porridge with the electric pressure cooker, the steam exhaust valve needs to be intermittently opened, i.e., the steam exhaust valve is opened for a period of time to exhaust a part of steam, then the steam exhaust valve is closed for a period of time to slowly cool down the porridge, and then the above operation is repeated.

[0078] Specifically, in the embodiment, it is first determined whether the total working duration of the heating module from starting working to the current time reaches the cooking setting time. When the total working duration reaches the cooking setting time, it is proved that the electric pressure cooker has finished cooking, at this time, the exhaust valve needs to be opened, and the application controls the exhaust valve action according to the exhaust strategy corresponding to the food type to complete the exhaust operation of the electric pressure cooker. If it is detected that the total working duration does not reach the cooking setting duration, the electric pressure cooker will continue to work, and the exhaust valve action does not need to be controlled, and the cooking work of the electric pressure cooker can be continued. In summary, in the embodiment, the exhaust strategy corresponding to the food type of the food to be cooked is selected after cooking based on the food type of the food to be cooked which has been determined, so as to avoid accidents such as water entering the electric pressure cooker or user scalding.

[0079] As a preferred embodiment, the food type includes juicy water food and less juicy water food.

[0080] According to the preset exhaust strategy corresponding to the food type, the electric pressure cooker is controlled to exhaust, comprising:

[0081] When the food type is juicy water food, the exhaust valve of the electric pressure cooker is controlled to be opened for a first preset duration and then turned off for a second preset duration, and it is detected whether the electric pressure cooker is completely exhausted. If yes, the exhaust valve is controlled to stop action; if no, the step of controlling the exhaust valve of the electric pressure cooker to be turned on for a first preset duration and then turned off for a second preset duration is entered.

[0082] When the food type is less juicy water food, the exhaust valve is controlled to be opened until the electric pressure cooker is completely exhausted.

[0083] Please refer to Figure 2 , Figure 2 Another flowchart of a method for determining a food type of an electric pressure cooker provided by the application.

[0084] In view of the fact that different foods have different needs for the steam exhaust strategy of the electric pressure cooker, different steam exhaust strategies are formulated for foods with more juice and foods with less juice in this embodiment. Since foods with more juice are prone to juice overflow and other problems during steam exhaust, the steam exhaust valve of the electric pressure cooker is controlled to be intermittently opened when the electric pressure cooker is cooking foods with more juice. Specifically, when the food type is foods with more juice, the steam exhaust valve of the electric pressure cooker is controlled to be opened for a first preset time period and then closed for a second preset time period, that is, the steam exhaust valve is controlled to be intermittently opened, and it is continuously detected whether the electric pressure cooker is completely exhausted. If the electric pressure cooker is completely exhausted, the steam exhaust valve is directly controlled to be closed. If the electric pressure cooker is not completely exhausted, the steam exhaust valve is continuously controlled to be intermittently opened, thereby avoiding the problem of juice overflow from the steam exhaust valve due to the large water content of the food. When the food type is foods with less juice, juice overflow is usually not a problem, so the steam exhaust valve can be controlled to be continuously opened until the electric pressure cooker is completely exhausted, and then the steam exhaust valve is controlled to be closed, which simplifies the control strategy of the steam exhaust valve under the premise of ensuring normal steam exhaust of the electric pressure cooker.

[0085] As a preferred embodiment, before entering the step of judging whether the working time of the electric pressure cooker is greater than the preset detection time, the method further comprises:

[0086] When the total working time does not reach the cooking setting time, it is judged whether the bottom temperature of the electric pressure cooker is greater than the cooking protection temperature;

[0087] If the bottom temperature is greater than the cooking protection temperature, the step of controlling the steam exhaust of the electric pressure cooker according to the preset steam exhaust strategy corresponding to the food type is entered;

[0088] If the bottom temperature is not greater than the cooking protection temperature, it is judged whether the food type of the food to be cooked has been determined;

[0089] If the food type has been determined, the step of judging whether the total working time of the heating module from the start of work to the current time reaches the cooking setting time is entered;

[0090] If the food type has not been determined, the step of judging whether the working time of the electric pressure cooker is greater than the preset detection time is entered.

[0091] The situation that the steam exhaust valve of the electric pressure cooker needs to be opened includes not only the situation that the food needs to be taken out after the cooking of the electric pressure cooker is completed, but also the situation that the pressure in the electric pressure cooker is too large, that is, the temperature of the electric pressure cooker is too high, and the electric pressure cooker needs to be protected from being damaged. Therefore, in the embodiment, whether the bottom temperature of the electric pressure cooker is greater than the cooking protection temperature is determined before the cooking of the electric pressure cooker is completed, that is, before the total working time reaches the cooking setting time. If the bottom temperature of the electric pressure cooker is greater than the cooking protection temperature, it is indicated that the steam exhaust valve needs to be temporarily opened to ensure the safety of the electric pressure cooker, and therefore the step of controlling the steam exhaust of the electric pressure cooker according to the preset steam exhaust strategy corresponding to the food type is performed. If the bottom temperature of the electric pressure cooker is not greater than the cooking protection temperature, it is proved that the electric pressure cooker is in a relatively safe situation, and the electric pressure cooker can be normally used to continue to cook the food to be cooked. Therefore, whether the working time reaches the cooking setting time, that is, whether the cooking of the electric pressure cooker is completed, is determined in the case that the food type is determined. In the case that the food type is not determined, the step of determining whether the working time of the electric pressure cooker is greater than the preset detection time is performed to complete the determination of the food type. In summary, the safety of the electric pressure cooker is further ensured, and the use experience of the electric pressure cooker is optimized by controlling the steam exhaust of the electric pressure cooker according to the food type when the bottom temperature of the electric pressure cooker is greater than the cooking protection temperature.
