For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying 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 those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0065] Before introducing the embodiments of the present application, first, the application background of the embodiments of the present application will be explained:

[0066] In modern household kitchens, range hoods occupy an important position. Range hoods can discharge a large amount of cooking fumes generated during the cooking process, improve the air quality in the kitchen, protect the health of family members, reduce the deposition of fumes, ensure the comfort and cleanliness of the kitchen environment. At the same time, range hoods can significantly reduce the accumulation of grease in the cooking area, reduce the hidden danger of fire, and improve the safety of the kitchen.

[0067] Currently, a switch is provided on the control panel of the range hood, and the switch can be a push-button, a rotary button, or a touch button. When cooking, users can manually turn on the range hood through the switch on the control panel.

[0068] However, with the development of technology, the intelligence of household appliances is increasingly needed by people. In the smart kitchen scenario, as the main kitchen appliance, the range hood also needs to improve its intelligence. However, in the prior art, the method of manually turning on the range hood has low intelligence and poor user experience.

[0069] In view of the above problems, the inventor found that when studying the user's cooking process, there is a certain pattern in the temperature change of the cooking area at the beginning of the user's cooking. Based on this, the inventor considered that the startup condition could be preset according to this temperature change pattern. In this way, when the user is cooking, the user does not need to manually turn on the range hood. The electronic device collects the temperature of the cooking area and determines whether the temperature meets the startup condition, so as to turn on the range hood when the condition is met, effectively improving the intelligence of the range hood startup method and the user experience.

[0070] Next, the technical solution of the present application will be described in detail through specific embodiments.

[0071] It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

[0072] Figure 1 FIG. is a schematic flowchart of the first embodiment of the startup control method of the range hood provided by the embodiment of the present application. As Figure 1 shown, the startup control method of the range hood may include the following steps:

[0073] S11. Obtain the initial ambient temperature of the cooking area.

[0074] The execution subject of the present application is an electronic device, which may be a terminal device, such as a mobile phone, a laptop computer, a desktop computer, etc., may be a server, or may be a range hood. In practical applications, whether the electronic device is specifically a terminal device, a server, or a range hood can be determined according to the actual situation, and no specific limitation is imposed thereon.

[0075] In this step, the range hood is provided with a temperature detection module, which is used to collect the ambient temperature of the cooking area. Since the ambient temperature of the cooking area is different when cooking in different environments. For example, in the same steaming scenario, the ambient temperature of the cooking area in summer is higher than that in winter. Therefore, it is necessary to first determine the initial ambient temperature of the cooking area before the stove is ignited, so as to determine the temperature range that the cooking area should be in when starting to cook in this environment based on the initial ambient temperature.

[0076] Among them, the cooking area refers to the area where oil fumes and odors are generated during cooking.

[0077] In a possible implementation manner, obtain the average temperature of the cooking area within a second preset duration. If the average temperature is less than or equal to a third preset temperature, then determine the third preset temperature as the initial ambient temperature. If the average temperature is greater than the third preset temperature and less than a fourth preset temperature, then determine the average temperature as the initial ambient temperature. If the average temperature is greater than or equal to the fourth preset temperature, then determine the fourth preset temperature as the initial ambient temperature.

[0078] In a specific example, the second preset duration can be 1 minute, the third preset temperature can be 10 °C, and the fourth preset temperature can be 35 °C. Before the stove is ignited, the average temperature in the cooking area is collected within 1 minute. If the average temperature is less than or equal to 10 °C, the initial ambient temperature is determined to be 10 °C; if the average temperature is greater than 10 °C and less than 35 °C, the average temperature is determined as the initial ambient temperature; if the average temperature is greater than or equal to 35 °C, the initial ambient temperature is determined to be 35 °C.

[0079] It should be understood that the second preset duration, the third preset temperature, and the fourth preset temperature can also be other values, which can be preset according to experimental values or empirical values, and no specific restrictions are imposed thereon.

[0080] In one implementation, the initial ambient temperature of the cooking area can be determined within a preset time period. The preset time period is a period with a low probability of cooking, such as 3 am or 4 am, etc. This time period can be preset according to the user's personal cooking habits or can be uniformly set by relevant staff, and can be selected according to the actual situation, and no specific restrictions are imposed thereon.

[0081] In practical applications, the initial ambient temperature can be updated at a certain frequency. For example, the initial ambient temperature of the cooking area is determined once a day or once a week, that is, the initial ambient temperature of the cooking area is updated once a day or once a week.

[0082] In another implementation, if the ambient temperature collected in the previous time period does not meet the startup condition, the average value of the ambient temperature collected in the previous time period is determined as the initial ambient temperature. Among them, the relevant description of the startup condition will be elaborated in the following steps and will not be repeated here.

[0083] S12. Determine the low-temperature range according to the initial ambient temperature and the preset temperature.

[0084] In this step, after determining the initial ambient temperature of the cooking area, calculations can be performed based on the initial ambient temperature to determine the low-temperature range that the cooking area should be in when cooking starts at this initial ambient temperature. That is to say, the low-temperature range is the temperature range where the cooking area is located when cooking starts.

[0085] In a possible implementation, the target temperature can be determined according to the initial ambient temperature, the first preset temperature, the second preset temperature, and the preset coefficient, and the low-temperature range is determined to be less than or equal to the target temperature. That is to say, the low-temperature range is from 0 to the target temperature.

[0086] In this implementation, the target temperature can be determined according to the formula: y = (a1 - x) × b + a2 + x.

[0087] Wherein, y is the target temperature, x is the initial ambient temperature, b is a preset coefficient, a1 is the first preset temperature, and a2 is the second preset temperature.

[0088] In a specific example, b can be 0.25, a1 can be 40 °C, and a2 can be 10 °C. That is to say, the above formula can be implemented as: y = (40 - x) × 0.25 + 10 + x.

[0089] It should be understood that the above preset coefficient, the first preset temperature, and the second preset temperature can be other values, which can be preset according to experimental values or empirical values, and no specific restrictions are imposed thereon.

[0090] S13. Determine the ambient temperature of the cooking area at each acquisition moment.

[0091] In this step, the ambient temperature of the cooking area can be collected so as to determine whether the cooker is currently being used for cooking based on the collected ambient temperature.

[0092] In a possible implementation manner, start timing and obtain the timing duration. Before the timing duration reaches the first preset duration, obtain the ambient temperature of the cooking area at each acquisition moment according to a preset frequency. When the timing duration reaches the first preset duration, stop timing.

[0093] In a specific example, the first preset duration can be 10 seconds, 30 seconds, 60 seconds, etc., and the preset frequency can be once per second. In this example, start timing and obtain the ambient temperature of the cooking area at each acquisition moment at a frequency of once per second.

[0094] It should be understood that the average ambient temperature of the cooking area between the current acquisition moment and the previous acquisition moment can be determined as the ambient temperature of the cooking area at the current acquisition moment. For example, the average ambient temperature from the start of timing to the first second is determined as the ambient temperature of the cooking area at the first acquisition moment; the average ambient temperature from the first second to the second second is determined as the ambient temperature of the cooking area at the second acquisition moment; the average ambient temperature from the second second to the third second is determined as the ambient temperature of the cooking area at the third acquisition moment... and so on until the timing duration reaches the first preset duration.

[0095] S14. If the ambient temperature of the cooking area at each acquisition moment satisfies the startup condition, then control the range hood to start up.

[0096] In this step, after obtaining the ambient temperature of the cooking area at each acquisition moment, it is determined whether the ambient temperature of the cooking area at each acquisition moment meets the startup condition. If so, it indicates that cooking is being performed using the cooker at this time, and the range hood is controlled to start up; if the ambient temperature of the cooking area at any acquisition moment does not meet the startup condition, it indicates that cooking is not being performed at this time, and S13 is re-executed to re-obtain the ambient temperature of the cooking area at each acquisition moment. Among them, the startup condition includes a low-temperature range.

[0097] In a possible implementation manner, after determining the ambient temperature of the cooking area at each acquisition moment, it is also possible to determine the temperature difference and temperature change trend between each acquisition moment and the previous acquisition moment. Specifically, for the i-th acquisition moment, the temperature difference and temperature change trend between the ambient temperature of the cooking area at the (i - 1)-th acquisition moment and the ambient temperature of the cooking area at the i-th acquisition moment are determined. Among them, i is a positive integer greater than or equal to 2.

[0098] Optionally, for the first acquisition moment, the temperature difference is 0 and the change trend is unchanged.

[0099] In this implementation manner, if the determined multiple temperature differences, multiple temperature change trends, and the ambient temperature of the cooking area at each acquisition moment all meet the startup condition, the range hood is controlled to start up.

[0100] Exemplarily, the startup condition may include at least one of the following:

[0101] Startup condition 1: The first preset duration is 10 seconds, and the preset frequency is once per second. The number of rising change trends within 10 seconds is greater than or equal to 8 times; and the difference between the ambient temperature at the 5th second and the ambient temperature at the 1st second is greater than or equal to 2 °C; and the ambient temperature at each second from the 6th to the 10th second is greater than or equal to the first temperature; and the ambient temperature at each acquisition moment is within the low-temperature range; and there cannot be a drastic temperature change within 10 seconds (that is, the temperature difference between each acquisition moment and the previous acquisition moment does not exceed the second temperature).

[0102] Among them, the first temperature can be calculated by the following formula:

[0103] Initial first temperature = ambient temperature at the 1st second × (40 - initial ambient temperature) × 0.1 + 1

[0104] It should be understood that if the initial first temperature calculated by the above formula is less than 2, 2 is determined as the first temperature; otherwise, the initial first temperature is determined as the first temperature.

[0105] Among them, the second temperature can be calculated by the following formula:

[0106] Second temperature = (initial ambient temperature - 10) × 0.01 + 4

[0107] Startup condition 2: The first preset duration is 10 seconds, and the preset frequency is once per second. The 10 change trends within 10 seconds are all upward; and the ambient temperature at the 10th second should be greater than the first temperature (the calculation method of the first temperature can refer to the method in startup condition 1); and the ambient temperature at each acquisition moment is within the low-temperature range; and there should be no drastic temperature changes within 10 seconds (that is, the temperature difference between each acquisition moment and the previous acquisition moment does not exceed the second temperature (the calculation method of the second temperature can refer to the formula in startup condition 1).

[0108] Condition 1 and condition 2 are applicable to most cooking scenarios and cookware. When there are not many low-temperature ingredients in the pot, the range hood can be basically turned on within 10 seconds after the stove ignites through condition 1 and condition 2. Among them, condition 1 is more suitable for iron pans, and condition 2 is more suitable for non-stick pans with slightly worse thermal conductivity.

[0109] Startup condition 3: The first preset duration is 30 seconds, and the preset frequency is once per second. The number of upward change trends within 30 seconds is greater than 12 times; and the difference between the number of upward change trends and the number of downward change trends is greater than or equal to 5; and the number of downward change trends is less than 7 times; and the ambient temperature at the 30th second is greater than the third temperature; and the temperature difference between each acquisition moment and the previous acquisition moment does not exceed 0.3 °C; and the ambient temperature at each acquisition moment is within the low-temperature range; and there should be no drastic temperature changes within 30 seconds (that is, the temperature difference between each acquisition moment and the previous acquisition moment does not exceed the second temperature (the calculation method of the second temperature can refer to the formula in startup condition 1).

[0110] Among them, the third temperature can be calculated by the following formula:

[0111] Initial third temperature = ambient temperature at the 1st second × (40 - initial ambient temperature) × 0.1

[0112] It should be understood that if the initial third temperature calculated by the above formula is less than 1, then 1 is determined as the third temperature; otherwise, the initial third temperature is determined as the third temperature.

[0113] Startup condition 4: The first preset duration is 60 seconds, and the preset frequency is once per second. The number of rising trends within 60 seconds is greater than 24; and the difference between the number of rising trends and the number of falling trends is greater than or equal to 9; and the number of falling trends is less than 14; and the ambient temperature at the 60th second is greater than the third temperature (the calculation method of the third temperature can refer to the formula in startup condition 3); and the temperature difference between each acquisition moment and the previous acquisition moment does not exceed 0.3 °C; and the ambient temperature at each acquisition moment is within the low-temperature range; and there is no drastic temperature change within 60 seconds (that is, the temperature difference between each acquisition moment and the previous acquisition moment does not exceed the second temperature (the calculation method of the second temperature can refer to the formula in startup condition 1)).

[0114] Startup conditions 3 and 4 supplement cooking scenarios that do not meet startup conditions 1 and 2. In scenarios where the temperature of the cooking area changes slowly after ignition of cookers such as stainless steel saucepans and steamers, the range hood can generally be controlled to start within 30 seconds after ignition; in scenarios such as casserole pots or when there are a lot of cold ingredients like cold water in the pot, the temperature change in the cooking area after ignition is extremely slow, and it can generally start automatically after 60 seconds after ignition.

[0115] It should be understood that the values in the above startup conditions are determined through a large number of experimental verifications and can also be set to other values, which can be determined according to the actual situation and are not specifically limited herein.

[0116] The startup control method of the range hood provided by the embodiment of the present application obtains the initial ambient temperature of the cooking area; then determines the low-temperature range according to the initial ambient temperature and the preset temperature; then determines the ambient temperature of the cooking area at each acquisition moment. If the ambient temperature of the cooking area at each acquisition moment meets the startup conditions, the range hood is controlled to start. In this technical solution, the startup conditions can be set in advance according to a large amount of temperature data of the cooking area during cooking, and the startup conditions are used to judge whether the current situation is a cooking scenario. In this way, it can be judged whether the current situation meets the startup conditions according to the ambient temperature of the cooking area at each acquisition moment, so as to control the range hood to start when satisfied, without manual operation, improving the intelligence of the startup operation and ensuring the user experience.

[0117] When conducting cooking experiments, the experimental conditions are selected as cooking methods such as frying, stir-frying, stewing, steaming, boiling, etc., cookware such as iron pans, frying pans, non-stick pans, saucepans, steamers, casserole pots, and room temperatures of 10 °C, 15 °C, 20 °C, 25 °C, 30 °C, 35 °C. The above experimental conditions are arranged in combinations, and different ingredients are matched at the same time. More than 100 cooking conditions are listed, data is collected throughout the cooking process to generate a cooking curve, and the user's cooking behavior is marked on the cooking curve to judge the ignition time.

[0118] Based on the above data, determine the startup conditions covering various cooking conditions, which can accurately determine whether it is currently in a cooking scenario.

[0119] Further, based on the startup control method of the range hood provided in the above embodiments, when testing whether the range hood can be accurately started automatically, Figure 2 This is a schematic diagram of the cooking curve provided by the embodiments of the present application. As Figure 2 shown, the horizontal axis is the temperature of the cooking area (unit: °C), and the vertical axis is the time (unit: seconds). Based on this cooking curve, it can be clearly seen that after the cooking utensil is ignited, the temperature of the cooking area gradually rises, and when the startup condition is met, the range hood is controlled to start automatically.

[0120] It should be understood that Figure 2 the ambient temperature in

[0121] is the initial ambient temperature of the above-mentioned cooking area.

[0122] Table 1

[0123] Further, based on the above experiments, a mis-trigger test was also conducted on the range hood to test whether the automatic startup of the range hood would be mis-triggered due to other operations.

[0124] Exemplarily, the test results of each operation can be represented by Table 2.

[0125] Table 2

[0126] Referring to Table 2, it can be seen that none of the daily operations mis-trigger the automatic startup of the range hood, indicating that the accuracy of the startup control method of the range hood provided by the present application is relatively high.

[0127] Generally speaking, the present application uses the temperature of the cooking area as a judgment condition. By collecting the temperature of the cooking area at a high frequency in the temperature detection module of the range hood device, through the temperature change, the cooking environment and the user's cooking behavior can be accurately judged, so as to control the automatic startup of the range hood, with a relatively high degree of intelligence and ensuring the user experience. At the same time, by identifying the user's ignition behavior from multiple scenarios, it does not picky about cookware or stoves, starts automatically, and sets startup conditions to avoid the range hood being mis-started.
