Description
Technical Field
[0001] This application relates to the field of control technology, specifically to an operation state control method, system, and intelligent cooking system. Background Technology
[0002] In modern life, people have increasingly higher demands for intelligent cooking systems. Smart cooktops and range hoods aim to optimize the cooking experience, using temperature control probes and infrared smoke sensors to control heat and manage fumes. Smart cooktops assist users in timely operation by monitoring the temperature of the pot bottom, while range hoods adjust their fan speed according to the smoke concentration.
[0003] However, smart cooktops face some challenges in practical applications. For example, cookware of different materials, thicknesses, and shapes can cause deviations in the temperature control probe's measurements, resulting in inaccurate temperature control and affecting cooking performance. Similarly, the infrared smoke sensor in a range hood has a certain lag, as it can only detect fumes when they rise to the air inlet. This can lead to insufficient extraction power in the early stages of fume concentration, allowing some fumes to already have diffused into the kitchen space.
[0004] Therefore, existing smart cooktops and range hood systems suffer from inaccurate temperature measurement and delayed fume extraction, resulting in unsatisfactory cooking results and kitchen environment control, which are problems that urgently need to be solved. Summary of the Invention

[0024] When the target object is determined to operate according to the preset operation prompt information for adding ingredients based on the second current temperature, the speed of the range hood is increased;
[0025] When the range hood speed increases, the stove's firepower level is adjusted based on the current temperature and the preset temperature, through wireless linkage.
[0026] Furthermore, based on the range hood's wireless linkage, the cooktop's heat level is adjusted according to the current temperature and the preset temperature, including:

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0052] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of the embodiments of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the present application described herein can be implemented in orders other than those illustrated or described herein. Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.
[0053] In modern life, many people struggle with cooking because they can't control the heat properly, resulting in dishes that don't taste as expected. To address this, smart cooktops have been introduced to the market, equipped with temperature control probes that rest against the bottom of the pot. By detecting the pot's temperature, they indirectly monitor the temperatures of cooking oil, broth, and other substances inside. This allows for intelligent temperature display, control, and reminders to add oil, vegetables, and seasonings at the appropriate temperatures. However, this method of indirectly detecting issues by installing temperature control probes on the cooktop is prone to inaccuracies due to variations in pot materials, thicknesses, and shapes. It's difficult to apply a single model that doesn't require additional user input, leading to significant temperature deviations and unsatisfactory results.
[0054] Meanwhile, intelligent control of cooking fumes during the cooking process to achieve a superior cooking experience is also a necessary demand for modern consumers. Range hoods with integrated fume sensors are already available on the market. These sensors, installed in the air duct, detect the concentration of smoke in the optical path using a tube-to-tube configuration, thereby determining the amount of smoke and controlling the range hood's fan speed. However, these infrared smoke sensors also have a certain lag, as they can only be detected when the smoke rises to the air inlet. This may result in insufficient extraction power in the initial stages of smoke concentration, allowing some smoke to already have diffused into the kitchen space.
[0055] Therefore, existing smart cooktops and range hood systems suffer from inaccurate temperature measurement and delayed fume extraction, resulting in unsatisfactory cooking results and kitchen environment control, which are problems that urgently need to be solved.
[0056] Based on this, such as Figure 1 As shown, this application proposes an operation state control method, the method comprising:
[0057] S10: Obtain the temperature of the inner surface of the stove cavity to get the first current temperature.
[0058] For example, in order to control the operating status of the stove and range hood, the temperature of the inner surface of the pot located on the stove can be accurately obtained by acquiring the temperature of the inner surface of the stove cavity, and the acquired temperature is used as the first current temperature.
[0059] Optionally, the temperature acquisition method is non-contact, and the installation position is not on the stove. The non-contact method measures the temperature at the center of the stove, which solves the problem of inaccurate measurement caused by adding a temperature control probe to the stove body, and achieves more accurate measurement of the temperature of cooking oil and soup in the pot.
[0060] S30: Compare the first current temperature with the preset temperature threshold to obtain the temperature comparison result.
[0061] S50: Based on the temperature comparison results, send a preset operation prompt message to the target object.
[0062] For example, to improve the taste of cooked dishes, each step of each dish has an optimal temperature, namely the preset temperature threshold in this embodiment of the application; that is, there is more than one preset temperature threshold. In order to determine the operation to be performed, it is necessary to first compare the obtained first current temperature with the preset temperature threshold to obtain a temperature comparison result.
[0063] When the temperature comparison result indicates that the current temperature has reached the preset temperature threshold, a preset operation prompt message is sent to the target object.
[0064] Optionally, the preset operations include, but are not limited to, operations during the cooking process such as adding ingredients, adding water, covering the pot with a lid, and adding seasonings.
[0065] Optionally, the target object can be a natural person, or an execution subject such as a robot or robotic arm used to perform cooking operations.
[0066] Optionally, preset operation prompts can be sent to the target audience via voice, SMS, application push notifications, or other means.
[0067] S70: Obtain the operation result based on the target object according to the preset operation prompt information, adjust the operating status of the range hood based on the operation result, and adjust the operating status of the stove based on the operating status of the range hood.
[0068] For example, the operation result obtained by the target object according to the preset operation prompt information is obtained. That is, the target object will perform an operation according to the preset operation prompt information and obtain the operation result, and the operation result is obtained.
[0069] Based on the obtained operation results and the preset operations corresponding to the preset operation prompts, the operating status of the range hood is adjusted.
[0070] Optionally, adjusting the operating status of the range hood mainly involves adjusting its rotation speed.
[0071] For example, after the operating status of the range hood is adjusted, the stove adjustment information corresponding to the operating status adjustment information of the range hood is sent to the stove, thus realizing the adjustment of the stove's operating status based on the operating status of the range hood.
[0072] Optionally, adjusting the operating status of the stove mainly involves adjusting the firepower of the stove.
[0073] This application provides an operational status control method, which involves obtaining the temperature of the inner surface of the stove cavity to obtain the current temperature; comparing the current temperature with a preset temperature threshold to obtain a temperature comparison result; sending preset operation prompt information to a target object based on the temperature comparison result; obtaining the operation result obtained by the target object based on the preset operation prompt information; adjusting the operating status of the range hood based on the operation result; and adjusting the operating status of the stove based on the operating status of the range hood. Through the linkage control of the stove and the range hood, the operating status of the range hood and the stove can be adjusted according to the cooking steps, and the temperature detection accuracy of the inner surface of the stove cavity is improved. This improves the kitchen environment, enhances the taste of the cooked dishes, and improves the user experience and satisfaction.
[0074] As an optional implementation method, after step S70, the method further includes:
[0075] The temperature of the inner surface of the stove cavity is repeatedly acquired to obtain the first current temperature. The operation status of the stove is adjusted based on the operating status of the range hood until all the operation steps in the smart recipe are executed.
[0076] For example, after adjusting the operating status of the stove, it does not mean that the control of the entire operating status has been completed. Instead, the above steps S10 to S70 will be repeated until all the operation steps in the smart recipe are executed.
[0077] This application also provides a specific embodiment to illustrate the above method. Taking the cooking of crispy pork as an example, the above method is explained. For example, cooking crispy pork includes steps such as adding cooking oil, adding raw meat, stir-frying, removing from the pan, and turning off the heat. The specific method for controlling the operation state of the cooking process is as follows:
[0078] 1. Obtain the temperature of the inner surface of the stove to get the current temperature A1; based on the operation steps of the smart recipe, the current preset operation is to add cooking oil, and the preset temperature threshold corresponding to adding cooking oil is B1; compare A1 and B1, and when A1 meets B1, send a preset operation prompt message for adding cooking oil to the target object; continue to obtain the temperature of the inner surface of the stove to get the current temperature A2, compare A2 with the preset temperature threshold B2 after adding cooking oil, obtain the temperature difference between A2 and B2, determine whether the target object has added cooking oil, and adjust the operating status of the range hood after the target object has added cooking oil; based on the range hood, send the stove operating status adjustment strategy corresponding to adding cooking oil to the stove to realize the adjustment of the stove's operating status;
[0079] 2. Continue to acquire the temperature of the inner surface of the stove to obtain the current temperature A3; based on the operation steps of the smart recipe, the current preset operation is to add raw meat, and the preset temperature threshold corresponding to adding raw meat is B3; compare A3 and B3, and when A3 meets B3, send a preset operation prompt message for adding raw meat to the target object; continue to acquire the temperature of the inner surface of the stove to obtain the current temperature A4, compare A4 with the preset temperature threshold B4 after adding raw meat, obtain the temperature difference between A4 and B4, determine whether the target object has added raw meat, and adjust the operating status of the range hood after the target object has added raw meat; based on the range hood, send the stove operating status adjustment strategy corresponding to adding raw meat to the stove to realize the adjustment of the stove's operating status;
[0080] 3. The process of stir-frying, removing, and turning off the heat is similar to the process described above, and will not be described again here.
[0081] It should be noted that the specific adjustments to the operating status of the range hood and cooktop during the above process are determined based on the specific cooking operation, i.e., the preset operation. For example, when the preset operation is to add ingredients, generally under high temperature conditions, if a low-temperature ingredient is suddenly added to the pan, the alternating high and low temperatures will cause a large amount of smoke to rise. At this time, the current temperature will drop sharply. When the temperature drop is lower than the temperature difference specified in the recipe, it is confirmed that the ingredients have been added, and the range hood speed will be increased immediately, and the corresponding heat level of the cooktop will also be increased.
[0082] This application embodiment repeatedly obtains the temperature of the inner surface of the stove and adjusts the state of the stove. Through the linkage control of the stove and the range hood, the operating state of the stove and the range hood is controlled throughout the cooking process. The range hood and the stove can adjust their operating state according to the cooking steps, thereby improving the kitchen environment and enhancing the taste of the cooked dishes, thus improving the user experience and satisfaction.
[0083] As an optional implementation method, before step S30 above, before comparing the first current temperature with a preset temperature threshold to obtain a temperature comparison result, the method further includes:
[0084] S20: Based on the operation steps in the smart recipe, obtain preset operation prompts and preset temperature thresholds.
[0085] For example, based on the operation steps of each dish and the preset temperature threshold corresponding to each operation step stored in the smart recipe, when cooking starts, the smart recipe will determine multiple preset operation prompts, that is, multiple operation steps of the dish being cooked.
[0086] When the temperature comparison result indicates that the current temperature has reached the preset temperature threshold, the preset operation steps will be sent to the target object so that the target object can perform the corresponding operation according to the preset operation prompt information.
[0087] Optionally, the preset operation information obtained from the smart recipe includes not only cooking steps, such as adding cooking oil and ingredients, but also specific information such as the amount of cooking oil and water added, as well as time information, such as the steaming or cooking time. A reminder is sent again before the time is up. In other words, the preset operation information includes at least one of the following: operation steps, time information, and the amount of ingredients added.
[0088] Optionally, smart recipes can be used online or offline. When there is a network connection, they will be updated online. They can also be trained and adjusted according to user tastes and can be built based on machine learning models.
[0089] This application embodiment obtains preset operation prompts and preset temperature thresholds through intelligent recipes, realizing guidance for the cooking process based on intelligent recipes, which helps to improve the taste of the cooked recipes and enhances the user experience and satisfaction.
[0090] As an optional implementation method, in step S70 above, obtaining the operation result based on the target object according to the preset operation prompt information, adjusting the operating state of the range hood based on the operation result, and adjusting the operating state of the stove based on the operating state of the range hood include:
[0091] S701: After obtaining the operation result based on the target object according to the preset operation prompt information, continue to obtain the temperature of the inner surface of the stove cavity to obtain the second current temperature.
[0092] For example, after the target object obtains the operation result according to the preset operation prompt information, that is, after it is determined that the target object has performed the operation according to the preset operation prompt information, the temperature of the inner surface of the current stove cavity is obtained to obtain the second current temperature. That is, during any process of cooking, the real-time temperature is continuously obtained as the current temperature.
[0093] S702: Based on the second current temperature, if the target object is determined to operate according to the preset operation prompt information, adjust the operating status of the range hood.
[0094] For example, by judging the temperature difference between the new current temperature and the preset temperature threshold after the preset operation corresponding to the preset operation prompt information is executed, it can be determined whether the target object is operating according to the preset operation prompt information. After judging the temperature difference and determining that the target object is operating according to the received preset operation prompt information, the operating status of the range hood is adjusted according to the executed preset operation prompt information.
[0095] Optionally, the specific method for adjusting the operating status of the range hood according to the preset operation prompt information can be as follows: store the range hood operating status adjustment strategy corresponding to the preset operation prompt information in the smart recipe or range hood; after determining that the operation corresponding to the preset operation prompt information has been executed, obtain the corresponding range hood operating status adjustment strategy, and adjust the range hood based on the range hood operating status adjustment strategy.
[0096] Optionally, the operating status of the range hood can be adjusted, mainly including adjusting the speed of the range hood. The purpose is to predict in advance whether oil fumes will be generated or reduced based on the operation being performed, and adjust the operating status of the range hood accordingly. This can realize intelligent adjustment of the range hood based on cooking operations, avoiding the adjustment lag caused by adjusting the range hood based on the sensing results of the smoke sensor.
[0097] S703: Adjust the operating status of the cooktop based on the operating status of the range hood.
[0098] For example, when the range hood's operating status is adjusted, it means that the target object has completed the corresponding operation according to the preset operation prompts, that is, it enters the next cooking stage and adjusts the operating status of the stove according to the preset operation prompts.
[0099] Optionally, the operating status adjustment strategies for the range hood and the cooktop corresponding to the preset operation prompt information can be stored in the corresponding execution entity, that is, the operating status adjustment strategy for the range hood is stored in the range hood, and the operating status adjustment strategy for the cooktop is stored in the cooktop.
[0100] Optionally, the operating status adjustment strategies of the range hood and the cooktop corresponding to the preset operation prompt information can also be stored in the preset operation prompt information. When sending the preset operation to the target object, the operating status adjustment strategies of the range hood and the cooktop are sent to the range hood at the same time, and then the range hood sends the operating status adjustment strategy of the cooktop to the cooktop.
[0101] It should be noted that the operating status adjustment strategies for the range hood and the cooktop in this application are determined based on preset operations and the current temperature.
[0102] Taking the preset operation prompt message of adding cooking oil as an example, a specific embodiment is provided to illustrate the above method:
[0103] The system acquires the temperature of the inner surface of the cooktop, obtaining the current temperature A1. Based on the operation steps of the smart recipe, the current preset operation is to add cooking oil, and the preset temperature threshold corresponding to adding cooking oil is B1. A1 and B1 are compared. When A1 meets B1, a preset operation prompt message for adding cooking oil is sent to the target object. The system acquires the temperature of the inner surface of the cooktop, obtaining the current temperature A2. A2 is compared with the preset temperature threshold B2 after adding cooking oil to obtain the temperature difference between A2 and B2, determining whether the target object has added cooking oil. After the target object adds cooking oil, the operating status of the range hood is adjusted. Based on the range hood, the operating status adjustment strategy of the cooktop corresponding to adding cooking oil is sent to the cooktop to realize the adjustment of the cooktop's operating status.
[0104] This application embodiment obtains preset operation prompts based on intelligent recipes and sends them to the execution object. Based on the execution result of the execution object on the operation corresponding to the preset operation prompts, it adjusts the operating status of the range hood and the stove. Through the linkage control of the stove and the range hood, it realizes intelligent adjustment of the range hood and the stove according to the cooking steps. This allows the range hood and the stove to adjust their operating status according to the cooking steps, thereby improving the kitchen environment, enhancing the taste of the cooked recipes, and improving the user experience and satisfaction.
[0105] As an optional implementation, in step S30 above, sending a preset operation prompt message to the target object based on the temperature comparison result includes:
[0106] If the temperature comparison result indicates that the current temperature is greater than or equal to the preset temperature threshold, a preset operation prompt message for adding ingredients is sent to the target object based on the smart recipe.
[0107] For example, when the next preset operation obtained based on the target recipe is to add ingredients, the preset temperature threshold corresponding to adding ingredients is obtained at the same time. The first current temperature and the preset temperature threshold corresponding to adding ingredients are compared. When the obtained temperature comparison result is that the first current temperature is greater than or equal to the preset temperature threshold corresponding to adding ingredients, it is determined that ingredients can be added at present, and the preset operation information for adding ingredients is sent to the target object.
[0108] like Figure 2 As shown, in step S701 above, after obtaining the operation result based on the target object according to the preset operation prompt information, the temperature of the inner surface of the stove cavity is further obtained to obtain the second current temperature, including:
[0109] After obtaining the operation result based on the preset operation prompt information of the target object according to the added ingredients, the temperature of the inner surface of the stove cavity is obtained to obtain the second current temperature.
[0110] For example, after the target object performs an operation based on the preset operation prompt information for adding ingredients, that is, after obtaining the operation result obtained based on the preset operation prompt information for adding ingredients, that is, after determining whether the user has added ingredients, the temperature of the inner surface of the stove cavity is further obtained to obtain the second current temperature.
[0111] In step S702 above, adjusting the operating status of the range hood based on the second current temperature, after determining that the target object is operating according to the preset operation prompt information, includes:
[0112] When the target object is determined to operate according to the preset operation prompt information for adding ingredients based on the second current temperature, the speed of the range hood is increased;
[0113] For example, the second current temperature is compared with the preset temperature threshold after adding ingredients to obtain the temperature difference. Based on this temperature difference, it is determined that when the target object operates according to the preset operation prompt information for adding ingredients, the operating status control logic of the range hood is to increase the speed of the range hood. This is because in Chinese cuisine, the oil in the pot is usually hot before adding ingredients. At this time, when low-temperature ingredients are suddenly added to the pot, the high and low temperatures alternate, and a large amount of smoke will rise. It is necessary to immediately increase the speed of the range hood for smoke extraction.
[0114] In step S703 above, adjusting the operating status of the cooktop based on the operating status of the range hood includes:
[0115] When the range hood speed increases, the stove's heat level is adjusted based on the current temperature via wireless linkage.
[0116] For example, when the range hood speed increases, the range hood sends information about adding food to the stove via wireless linkage, obtains the preset temperature threshold corresponding to the addition of food, and adjusts the stove's firepower level based on the difference between the new current temperature and the preset temperature threshold corresponding to the addition of food.
[0117] Optionally, wireless connection methods include, but are not limited to, Wi-Fi, Bluetooth, ZigBee, etc.
[0118] This application embodiment determines whether to send a preset operation prompt message to add ingredients based on temperature comparison results, and determines whether the target object has completed adding ingredients based on the current temperature. Once it is confirmed that ingredients have been added, the range hood speed and the stove's heat level are adjusted. Through this process, the lag in controlling fumes using a smoke sensor and the lag in controlling the stove during ingredient addition are resolved. By linking the stove and range hood, the operating status of both the stove and range hood is controlled throughout the entire cooking process. This allows the range hood and stove to adjust their operating status according to the cooking steps, thereby improving the kitchen environment, enhancing the taste of the finished dish, and improving user experience and satisfaction.
[0119] As an optional implementation, the above-mentioned adjustment of the stove's heat level based on the range hood via wireless linkage, according to the second current temperature and the preset temperature, includes:
[0120] When the second current temperature is lower than the first temperature threshold, the range hood is wirelessly linked to adjust the firepower level of the stove to be higher than the first threshold.
[0121] When the second current temperature is lower than the first temperature threshold, the range hood is wirelessly linked to adjust the firepower level of the stove to be higher than the first threshold.
[0122] When the second current temperature is greater than the first temperature threshold and less than the second temperature threshold, the range hood is wirelessly linked to adjust the firepower level of the stove to be greater than the second level threshold and less than the first level threshold.
[0123] When the second current temperature is greater than the second temperature threshold and less than the third temperature threshold, the range hood is wirelessly linked to adjust the firepower level of the stove to be greater than the third threshold and less than the second threshold.
[0124] When the second current temperature is greater than the third temperature threshold and less than the fourth temperature threshold, the range hood is wirelessly linked to adjust the stove's firepower level to be less than the third threshold and greater than the fourth threshold.
[0125] When the second current temperature is greater than the fourth temperature threshold, the range hood is wirelessly linked to adjust the stove's firepower level to be lower than the fourth threshold and higher than the fifth threshold.
[0126] Among them, the first temperature threshold is less than the second temperature threshold, the second temperature threshold is less than the third temperature threshold, and the third temperature threshold is less than the fourth temperature threshold; the first gear threshold is greater than the second gear threshold, the second gear threshold is greater than the third gear threshold, the third gear threshold is greater than the fourth gear threshold, and the fourth gear threshold is greater than the fifth gear threshold.
[0127] For example, after adding ingredients, the specific heat level of the stove is determined by comparing the obtained second current temperature with a preset temperature threshold. The adjustment method is either to send the adjustment strategy to the stove via wireless linkage based on the range hood, and the stove adjusts directly according to the strategy; or to send the operation information and temperature information to the stove via wireless linkage based on the operation information and temperature information, and the stove adjusts its heat level accordingly.
[0128] Specifically, the strategy for adjusting the stove's operating status after adding ingredients is as follows:
[0129] 1. The stove has five threshold levels, and the specific relationship is as follows: first threshold level > second threshold level > third threshold level > fourth threshold level > fifth threshold level;
[0130] 2. The preset temperature thresholds include four preset temperature thresholds, and their relationship is as follows: first temperature threshold < second temperature threshold < third temperature threshold < fourth temperature threshold;
[0131] 3. The specific relationship between the temperature of the inner surface of the stove and the stove's heat level is as follows:
[0132] (1) When the second current temperature is less than the first temperature threshold, the firepower level of the stove is greater than the first threshold.
[0133] (2) When the first temperature threshold < the second current temperature < the second temperature threshold, the second gear threshold < the firepower level of the stove < the first gear threshold;
[0134] (3) When the second temperature threshold < the second current temperature < the third temperature threshold, the third gear threshold < the firepower level of the stove < the second gear threshold;
[0135] (4) When the third temperature threshold < the second current temperature < the fourth temperature threshold, the fourth gear threshold < the firepower level of the stove < the third gear threshold.
[0136] (5) When the second current temperature is greater than the first temperature threshold, the fifth gear threshold is less than the firepower level of the stove and the fourth gear threshold.
[0137] It should be noted that the first temperature threshold, the second temperature threshold, the third temperature threshold and the fourth temperature threshold mentioned above are obtained based on preset temperature thresholds.
[0138] During the addition of ingredients, the second current temperature is continuously obtained, and the temperature of the inner surface of the stove is maintained at the preset temperature threshold by controlling the firepower of the stove.
[0139] Introduce the above solution with a specific embodiment. The recommended temperature of the recipe is B (i.e., the preset temperature threshold). When the first current temperature reaches B, a preset operation prompt message for adding ingredients is sent to the target object. During the period when the target object adds ingredients, the second current temperature C is continuously obtained. The second current temperature C is the surface temperature C of the cooking oil, and the second current temperature C is compared with the preset temperature threshold B to determine the firepower level of the stove. Specifically, it includes:
[0140] 1) When the surface temperature C of the cooking oil < B - 20°C, the range hood controls the high firepower level of the stove through wireless linkage;
[0141] 2) When B - 20°C < the surface temperature C of the cooking oil < B - 10°C, the range hood controls the relatively high firepower level of the stove through wireless linkage;
[0142] 3) When B - 10°C < the surface temperature C of the cooking oil < B - 5°C, the range hood controls the medium firepower level of the stove through wireless linkage;
[0143] 4) When B - 5°C < the surface temperature C of the cooking oil < B + 10°C, the range hood controls the relatively low firepower level of the stove (the fourth gear threshold);
[0144] 5) When the surface temperature C of the cooking oil > B + 10°C, the range hood controls the low firepower level of the stove (the fifth gear threshold);
[0145] The above B - 20°C is the first temperature threshold, B - 10°C is the second temperature threshold, B - 5°C is the third temperature threshold, and B + 10°C is the fourth temperature threshold; the high firepower level corresponds to being greater than or equal to the first gear threshold, the relatively high firepower level is between the first gear threshold and the second gear threshold, the medium firepower level is between the second gear threshold and the third gear threshold; the relatively low firepower level is between the third gear and the fourth gear threshold; the low firepower level is between the fourth gear threshold and the fifth gear threshold.
[0146] Based on the above operating state adjustment strategy, it is possible to continuously cook at an appropriate oil temperature and make delicious dishes.
[0147] It should be noted that the above adjustment method based on temperature corresponding to different firepower levels is not limited to the process of adding ingredients. It is also applicable to other processes, but the temperature range and gear range can be different from the above process and should be adjusted adaptively according to the actual operation steps. The specific temperature range and gear range are not limited in this application, but the adjustment principle is the same: when the second current temperature is lower than the preset temperature threshold, the firepower level of the stove is increased, and when the second current temperature is higher than the preset temperature threshold, the firepower level of the stove is decreased.
[0148] This application embodiment adjusts the stove's firepower according to the difference between a preset temperature threshold and the current temperature. The temperature is transmitted wirelessly from the range hood to the stove, achieving coordinated adjustment between the stove and the range hood. This precise temperature control improves the taste of the cooked dishes and enhances the user experience and satisfaction.
[0149] As an optional implementation, before sending a preset operation prompt message for adding ingredients to the target object according to the smart recipe when the temperature comparison result indicates that the first current temperature is greater than or equal to a preset temperature threshold, the method further includes:
[0150] When the stove is in the start-up state and the temperature comparison result indicates that the current temperature is less than the preset temperature threshold, a preset operation prompt message for preparation work is sent to the target object.
[0151] For example, before adding ingredients, preparation work must be carried out. If the stove is in the start-up state and the temperature comparison result indicates that the current temperature is less than the preset temperature threshold, a preset operation prompt message for preparation work is sent to the target object.
[0152] Optionally, preparation work includes, but is not limited to, preheating the cookware and adding cooking oil.
[0153] Optionally, the notification message can be sent to the user via voice, SMS, application push notification, or other means.
[0154] As an optional implementation, the range hood is equipped with at least one temperature probe; the temperature probe is a non-contact temperature probe.
[0155] In step S10 above, obtaining the temperature of the inner surface of the stove cavity to get the first current temperature includes,
[0156] The temperature of the inner surface of the stove cavity is collected by at least one temperature probe to obtain the first current temperature.
[0157] For example, the temperature acquisition in this embodiment of the application is accomplished by at least one non-contact temperature probe installed on the body of the range hood.
[0158] This application embodiment uses at least one non-contact temperature probe installed on the body of the range hood to detect the temperature of the inner surface of the cooktop. This avoids the temperature measurement error problem caused by the material and size of the cookware when the temperature sensor is installed in the cooktop in the prior art. It achieves precise temperature control, improves the taste of the cooked dishes, and enhances the user experience and satisfaction.
[0159] As an optional implementation, when the stove is in the start-up state and the temperature comparison result indicates that the first current temperature is less than a preset temperature threshold, a preset operation prompt message for preparation is sent to the target object. After the target object receives the operation result in response to the preset operation prompt message for preparation, the temperature of the inner surface of the stove cavity continues to be collected. When the preset temperature reaches the preset temperature threshold corresponding to adding ingredients, a first preset operation prompt message for adding ingredients is sent.
[0160] After the target user responds to the first preset operation prompt message for adding ingredients and receives the operation result, the temperature of the inner surface of the stove cavity continues to be collected. If the monitored temperature change reaches or exceeds the first temperature difference value within the preset first time period, and the temperature change trend shows a downward trend, this indicates that the target user has added ingredients as prompted, causing the oil temperature to drop due to the addition of ingredients. Therefore, based on the temperature change of the inner surface of the stove cavity, it is determined that the target user has operated according to the first preset operation prompt message, thereby adjusting the operating status of the range hood and increasing its extraction speed to a state greater than the first speed value to enhance the extraction effect of oil fumes, while keeping the stove's firepower level unchanged to ensure the continuity of the cooking process and the cooking quality of the ingredients.
[0161] After the target user successfully adds ingredients and starts cooking, a second preset operation prompt is sent to the target user according to the next step of the smart recipe, prompting the target user to stir-fry. When the temperature of the inner surface of the cooktop cavity is detected to be higher than the first temperature value, and the temperature trend is upward, this usually means that the food is heating up and may begin to release steam or fumes. The range hood is adjusted to a speed greater than the second speed value to more effectively extract the fumes generated by stir-frying, and the cooktop firepower is adjusted to a level greater than the first threshold to ensure sufficient heat during the stir-frying process.
[0162] After the target user completes the initial cooking steps such as adding ingredients and stir-frying, a third preset operation prompt is sent to the target user according to the intelligent recipe process. This prompt may be for adding seasonings, adding water, or braising, depending on the recipe requirements and the current cooking stage. The temperature of the inner surface of the stove cavity continues to be collected. When the temperature change is greater than the second temperature difference value within a second preset time and the temperature change trend is downward, it is determined that the target user has operated according to the third preset operation prompt. The range hood is adjusted to a state where the exhaust speed is greater than the first speed value, and the stove's firepower level is adjusted to a state where it is greater than the third threshold and less than the second threshold, ensuring that the heat is moderate and suitable for braising ingredients.
[0163] When the temperature of the inner surface of the cooking cavity rises by a third temperature difference value within a third preset time, collect the temperature change of the inner surface of the cooking cavity. When the temperature change is greater than a fourth temperature difference value and the temperature change trend is an upward trend, this usually indicates that the food in the pot is being heated and may be about to reach the boiling point or requires further processing. Send a fourth preset operation prompt message to the target object. The fourth preset prompt message may be an open - lid prompt for the target object to perform the next operation, such as stirring or checking the cooking status of the food. Continue to collect the temperature of the inner surface of the cooking cavity. When the temperature change of the inner surface of the cooking cavity is greater than a sixth temperature difference value and the change trend is a downward trend, it is determined that the target object operates according to the fourth preset operation prompt message. At this time, the temperature in the pot begins to drop due to the influence of the external environment. Adjust the operating speed of the range hood to a state greater than the second speed value to cope with the oil fumes that may escape due to opening the lid; and adjust the cooking fire power level to a state greater than the third gear threshold and less than the second gear threshold to meet the cooking requirements of the food in the pot after opening the lid and maintain an appropriate heat.
[0164] Using the above process, this application realizes that with the intelligent recipe on the range hood or mobile phone APP, it will prompt the target object to perform relevant actions step by step. By monitoring the temperature in the pot body, it judges whether the customer follows the recipe step guidance, so as to control the cooking fire power of the cooker and the rotation speed of the range hood at each step.
[0165] This application also provides a complete cooking process. Taking fried meat with pakchoi as an example, the above - mentioned operation state control method is described.
[0166] 1. The customer confirms the recipe of fried meat with pakchoi on the range hood or mobile phone APP. Subsequently, the intelligent recipe sends the first preset operation prompt message to the customer, prompting the customer to heat the pot and add oil.
[0167] 2. Obtain the current temperature in the pot. When the infrared temperature measurement probe measures that the oil temperature rises to the healthy oil temperature value Aa, send the second preset operation prompt message to the customer, prompting the customer to add ingredients. At this time, continue to obtain the current temperature. When the infrared temperature measurement probe measures Ba, where Ba < Aa - Ca, showing a cliff - like temperature drop, it is determined that the customer has added low - temperature ingredients. The range hood accelerates the exhaust, and based on the relationship between Ba and Aa, adjust the cooking fire power of the cooker, which can be adjusted to the high - fire power level;
[0168] 3. After judging that the addition of ingredients is completed, send the third preset operation prompt message to the customer, prompting the customer to stir - fry. The infrared temperature measurement probe measures that the surface temperature of the ingredients gradually rises, and the temperature rises to the temperature point Da preset in the recipe. During this period, the range hood operates at a high level, and the cooker is controlled to operate at high fire;
[0169] 4. After determining that the stir-frying is completed, send the fourth preset operation prompt message to prompt the customer to add seasonings, add water, cover the pot, and the infrared temperature probe measures Ea, where Ea < Da - Fa, showing a cliff-like temperature drop, and determine that the customer has added seasonings, added water, and covered the pot lid. At this time, less oil fume is generated, and the range hood reduces its speed to medium-low speed, while the cooking stove operates at high firepower.
[0170] 5. After covering the pot lid, when the actual time reaches the pot lid covering time in the fifth preset operation prompt message of the intelligent step, and at the same time it is detected that the temperature of the pot lid has risen by Ga within the pot lid covering time, send the fifth preset operation prompt message to prompt the customer to open the lid. When Ga mutates to Ha, determine that the customer has indeed opened the lid. At this time, the range hood increases its suction, and the cooking stove operates at medium firepower, and send the sixth preset operation prompt message to prompt the customer to add seasonings, stir-fry, and take out of the pot; thus, with the assistance of the infrared temperature probe, through the linkage of the range hood and the cooking stove, and based on the intelligent recipe, the guidance for the customer is completed, and a delicious dish is successfully cooked.
