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

[0054] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0055] Before introducing the embodiments of the present disclosure, first, the application background of the embodiments of the present disclosure will be explained:

[0056] In modern household kitchens, range hoods occupy an important position. Range hoods can exhaust a large amount of oil fumes generated during cooking, improve the air quality in the kitchen, protect the health of family members, reduce the deposition of oil 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.

[0057] In practical applications, the amount of oil fumes generated in different cooking scenarios is different. For example, the amount of oil fumes generated during stewing is small, while the amount of oil fumes generated during stir-frying is large. Therefore, during actual use, it is necessary to adjust the gear of the range hood according to the amount of oil fumes generated during cooking.

[0058] At present, a gear button is set on the control panel of the range hood. The gear button can be a push type, a touch type or a rotary type. Users can manually adjust the gear button to adjust the wind speed of the range hood according to the actual generated oil fume during cooking.

[0059] However, in the above method, due to limited human energy, it is easy to forget to adjust the gear of the range hood when concentrating on cooking. At the same time, when the amount of oil fume is small, in order to ensure a better smoke exhaust effect, users will turn the range hood to a high gear, resulting in excessive energy consumption and affecting the service life of the range hood. That is to say, there is a problem of low accuracy in the way of manually adjusting the gear of the range hood.

[0060] With the development of technology, the intelligence of household appliances is more and more needed by people. As a main kitchen appliance, the range hood also needs to improve its intelligence in the kitchen intelligent scenario to match the user scenario requirements. However, in the existing technology, the intelligence is low by manually adjusting the gear of the range hood, and the user experience is poor.

[0061] In summary, the existing technology has problems of low intelligence and accuracy, and poor user experience.

[0062] In view of the above problems, the inventor found in the research of various cooking behaviors that different cooking behaviors require different gears of the range hood, and different cooking behaviors can be determined according to the ambient temperature in the cooking area. Based on this, after detecting that the range hood is turned on, the ambient temperature in the cooking area can be collected, and the cooking behavior at this time can be determined based on the change of the ambient temperature, so as to adjust the gear of the range hood according to the cooking behavior. In this way, the range hood can automatically adjust the gear according to the cooking situation without manual operation by the user, effectively improving the intelligence and accuracy of the gear adjustment of the range hood, ensuring that the user has enough energy to cook, and improving the user experience.

[0063] Next, the technical solution of the present disclosure will be described in detail through specific embodiments.

[0064] 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 repeated in some embodiments.

[0065] Figure 1 It is a schematic flowchart of the first embodiment of the gear adjustment method for the range hood provided by the embodiment of the present disclosure. As Figure 1 shown, the gear adjustment method for the range hood may include the following steps:

[0066] S11. After the range hood is turned on, collect the ambient temperature in the cooking area.

[0067] The execution subject of the embodiment of the present disclosure is an electronic device, which can be a terminal device, such as a mobile phone, a laptop computer, a desktop computer, etc., a server, or a range hood. In actual applications, the electronic device can be a terminal device, a server, or a range hood according to actual conditions, and the embodiment of the present disclosure does not specifically limit this.

[0068] In this step, since the ambient temperature of the cooking zone changes differently under different cooking behaviors, it is necessary to collect the ambient temperature of the cooking zone after the range hood is turned on, so as to subsequently determine the ambient temperature change of the cooking zone within a period of time.

[0069] Among them, the cooking area refers to the area where smoke and odor are generated during cooking.

[0070] Optionally, the range hood is provided with a temperature detection module, and the temperature detection module is used to collect the ambient temperature of the cooking zone.

[0071] In one possible implementation, the ambient temperature of the cooking zone can be collected in real time through the temperature detection module, the ambient temperature of the cooking zone can be collected through the temperature detection module at a preset frequency, and the ambient temperature of the cooking zone can be continuously collected for a period of time (for example, 1 second) each time the temperature detection module is collected, and the average value of the ambient temperature of the cooking zone collected during this period of time is determined as the ambient temperature collected this time.

[0072] Optionally, the electronic device and the range hood may be connected via a wired or wireless manner, and the electronic device obtains the working status of the range hood by communicating with the range hood.

[0073] S12. Determine temperature change information of the multiple ambient temperatures according to the multiple ambient temperatures collected continuously.

[0074] In this step, after the ambient temperature of the cooking zone is continuously collected, the change of the ambient temperature of the cooking zone during the collection process, i.e., the temperature change information, can be determined based on the multiple ambient temperatures collected continuously. The temperature change information includes the target temperature range corresponding to each of the multiple ambient temperatures, and the change trend and temperature difference between adjacent ambient temperatures in the multiple ambient temperatures.

[0075] The temperature range is determined in advance based on the initial ambient temperature of the cooking zone when no cooking is done, and the temperature range includes a low temperature range, a medium temperature range, and a high temperature range. The specific determination process can be achieved through the following steps:

[0076] Before the range hood is turned on, determine the initial ambient temperature of the cooking zone. According to the initial ambient temperature of the cooking zone, determine multiple temperature ranges.

[0077] In a possible 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 relatively 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, without specific restrictions on this.

[0078] In specific implementation, the average temperature of the cooking area within a certain period of time within the above-mentioned preset time period can be obtained. If the average temperature is less than or equal to the first preset temperature, then the first preset temperature is determined as the initial ambient temperature. If the average temperature is greater than the first preset temperature and less than the second preset temperature, then the average temperature is determined as the initial ambient temperature. If the average temperature is greater than or equal to the second preset temperature, then the second preset temperature is determined as the initial ambient temperature.

[0079] In a specific example, the above-mentioned period of time can be 1 minute, the first preset temperature can be 10 °C, and the second preset temperature can be 35 °C. Within the above-mentioned preset time period, the average temperature of the cooking area in 1 minute is collected. If the average temperature is less than or equal to 10 °C, then the initial ambient temperature is determined to be 10 °C; if the average temperature is greater than 10 °C and less than 35 °C, then the average temperature is determined as the initial ambient temperature; if the average temperature is greater than or equal to 35 °C, then the initial ambient temperature is determined to be 35 °C.

[0080] 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.

[0081] Since there are differences in the ambient temperature of the cooking area 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, when determining the cooking behavior according to the ambient temperature of the cooking area, it is necessary to combine the initial ambient temperature of the cooking area when there is no cooking, which can effectively improve the accuracy of subsequent judgments.

[0082] In a possible implementation, according to the initial ambient temperature of the cooking area, a first temperature and a second temperature are determined. The low temperature range is less than or equal to the first temperature, the medium temperature range is greater than the first temperature and less than the second temperature, and the high temperature range is greater than or equal to the second temperature.

[0083] Optionally, the first temperature and the second temperature can be calculated by the following formula:

[0084] y=(40 - x)×0.25 + 10 + x

[0085] z = (40 - x) × 0.25 + 15 + x

[0086] Wherein, y is the first temperature, z is the second temperature, and x is the initial ambient temperature.

[0087] S13. If the temperature change information of multiple ambient temperatures meets the target preset gear shifting condition among multiple preset gear shifting conditions, the gear of the range hood is adjusted according to the target preset gear shifting condition.

[0088] In this step, based on a large amount of cooking experiment data, the temperature environment change law of the cooking area corresponding to different cooking behaviors and the most suitable gear of the range hood for each cooking behavior can be determined in advance. Based on this, multiple gear shifting conditions are preset, and each preset gear shifting condition corresponds to a cooking behavior and at least one gear. In this way, in actual application, the determined temperature change information can be matched with each preset gear shifting condition to determine the target preset gear shifting condition that the temperature change information matches among multiple preset gear shifting conditions, so as to adjust the gear of the range hood according to this preset gear shifting condition.

[0089] In a possible implementation manner, the gear of the range hood can be adjusted to the target gear corresponding to the target preset gear shifting condition.

[0090] To further improve the accuracy of gear shifting adjustment, next, several other gear shifting methods are specifically introduced:

[0091] In a possible implementation manner, if the temperature change information of multiple ambient temperatures meets the target preset gear shifting condition, and the current gear of the range hood is greater than the target gear corresponding to the target preset gear shifting condition, and there is no other gear between the current gear and the target gear, the range hood is adjusted to the target gear.

[0092] Wherein, the gear of the range hood is positively correlated with the wind speed.

[0093] Exemplarily, the range hood can have three gears: stir-fry, high speed, and soft speed. The magnitude relationship of these three gears is: stir-fry > high speed > soft speed, and the magnitude relationship of the wind speeds corresponding to these three gears is: stir-fry > high speed > soft speed.

[0094] In this implementation manner, if the target gear corresponding to the target preset gear shifting condition is only one gear lower than the current gear, the gear of the range hood can be directly adjusted to the target gear.

[0095] In a possible implementation manner, if the temperature change information of multiple ambient temperatures meets the target preset gear shifting condition, and the current gear of the range hood is greater than the target gear corresponding to the target preset gear shifting condition, and there is a first gear between the current gear and the target gear, the range hood is adjusted to the first gear.

[0096] In this implementation, if the target gear corresponding to the target preset gear shifting condition is several gears lower than the current gear, it is necessary to adjust the gear of the range hood to the next gear below the current gear. For example, assume that the current gear is the stir-fry gear and the target gear is the gentle speed gear, and there is also a high-speed gear in between. Therefore, it is necessary to adjust the gear of the range hood to the high-speed gear.

[0097] When adjusting the gear of the range hood through this implementation, the gear of the range hood can only be adjusted downward one level at a time and cannot skip gears downward. The main reason is that in the scenario where a large amount of oil fume was generated in the previous cooking behavior and a high wind speed gear (such as stir-fry) was required for exhausting the fume, while less oil fume is generated in the current cooking behavior and a low wind speed gear (such as gentle speed) is used for exhausting the fume. Even though less oil fume is generated in the current cooking behavior, there is still residual oil fume from the previous cooking behavior in the current environment. If the gear is directly switched from a high wind speed gear to a low wind speed gear, it cannot guarantee the large oil fume emission demand in the current environment. Adjusting the gear downward one level can meet the oil fume emission demand on the basis of reducing energy consumption and improve the accuracy of gear adjustment.

[0098] In a possible implementation, if the temperature change information of multiple ambient temperatures meets the target preset gear shifting condition, and the current gear of the range hood is the same as the target gear corresponding to the target preset gear shifting condition, and the target gear is not the lowest gear of the range hood, then adjust the gear of the range hood to a gear one level lower than the target gear.

[0099] In this implementation method, if the current gear of the range hood is the same as the target gear, the gear of the range hood can be adjusted downward by one gear, which can effectively reduce the noise brought to the user by the range hood continuously running at a high gear and ensure the user's usage experience.

[0100] In a possible implementation, if the temperature change information of multiple ambient temperatures meets the target preset gear shifting condition, and the current gear of the range hood is less than the target gear corresponding to the target preset gear shifting condition, then adjust the gear of the range hood to the target gear.

[0101] In this implementation, if the current gear of the range hood is less than the target gear, then directly adjust the gear of the range hood to the target gear to meet the current large oil fume emission demand.

[0102] During the above adjustment process, after adjusting the range hood from the current gear to the second gear, control the range hood to continuously work at the second gear for a preset duration, and then re-collect the ambient temperature of the cooking area.

[0103] In any of the above implementation manners, when adjusting the range hood from one gear to another, after the adjustment, it is necessary to control the range hood to continuously work at the current gear for a period of time, then re-collect the ambient temperature of the cooking area, and re-determine whether it is necessary to adjust the gear of the range hood based on the re-collected ambient temperature of the cooking area. In this way, it is possible to effectively avoid frequent gear adjustment of the range hood, thereby preventing frequent gear adjustment from disturbing the user's cooking, reducing the energy consumption of the range hood, improving the accuracy of controlling the range hood, and ensuring the user's usage experience.

[0104] The gear adjustment method of the range hood provided by the embodiments of the present disclosure, after the range hood is turned on, collects the ambient temperature of the cooking area, and determines the temperature change information of multiple ambient temperatures according to the multiple continuously collected ambient temperatures. If the temperature change information of the multiple ambient temperatures meets the target preset gear adjustment condition among the multiple preset gear adjustment conditions, the gear of the range hood is adjusted according to the target preset gear adjustment condition. Among them, the temperature change information includes the target temperature range corresponding to each ambient temperature among the multiple ambient temperatures, as well as the change trend and temperature difference between adjacent ambient temperatures among the multiple ambient temperatures. In this technical solution, the preset gear adjustment conditions are determined based on a large amount of cooking experiment data, which is used to represent the gear of the range hood required for each cooking behavior. By matching the temperature change information of the cooking area within a period of time with the multiple preset gear adjustment conditions, the gear of the range hood is adjusted according to the obtained target preset gear adjustment condition, realizing the automatic adjustment of the range hood gear during the cooking process, liberating the user's hands, meeting the requirement of zero manual operation throughout the cooking process, improving the intelligence and accuracy of the adjustment, and ensuring the user's usage experience.

[0105] Next, specific explanations will be given to the relevant data of the cooking experiment and the various gear adjustment conditions determined based on the cooking experiment data.

[0106] In the cooking experiment, the experimental conditions selected are cooking methods such as frying, deep-frying, stir-frying, stewing, steaming, and boiling, cooking utensils such as iron pans, frying pans, non-stick pans, soup pots, steamers, and casserole pots, and room temperatures of 10°C, 15°C, 20°C, 25°C, 30°C, and 35°C. The above experimental conditions are arranged in combinations, and different ingredients are paired at the same time, listing more than 100 cooking conditions, collecting data throughout the cooking process, generating a cooking curve, and marking the user's cooking behavior on the cooking curve.

[0107] Figure 2 This is a schematic diagram of a cooking curve provided by the embodiments of the present disclosure. As Figure 2 shown, the horizontal axis of this cooking curve is the temperature of the cooking area (unit: °C), and the vertical axis is the time (unit: second). This cooking curve includes various cooking behaviors, which are respectively:

[0108] a. Hot pot heating up: The ambient temperature in the cooking area rises, and the duration of the rising trend is greater than a certain value. At this time, the range hood should be turned on.

[0109] b. Oil getting hot: The ambient temperature in the cooking area is in the high-temperature range, with a large temperature difference and in a rapid heating state, generating a large amount of oil fume. At this time, the range hood should be set to the stir-fry gear.

[0110] c. Adding ingredients to cool down: The ambient temperature in the cooking area is in the medium-temperature range or the high-temperature range, with a large temperature difference and in a rapid cooling state, generating a large amount of oil fume. At this time, the range hood should be set to the stir-fry gear.

[0111] d. Covering the pot and simmering: After a period of time, the ambient temperature in the cooking area is in the medium-temperature range or the low-temperature range, with a small temperature difference change. At this time, the range hood should be set to the gentle speed gear.

[0112] e. Opening the lid to add ingredients and check: The ambient temperature in the cooking area is on the rise, with a large temperature difference. In this scenario, a large amount of smoke is generated. At this time, the range hood should be set to the high-speed gear.

[0113] f. Taking the dish out of the pot: When the ambient temperature in the cooking area drops and the duration of the dropping trend is less than a certain value, the range hood should be turned off at this time.

[0114] Among them, Figure 2 the ambient temperature mentioned above is the initial ambient temperature in the cooking area.

[0115] It should be understood that the above temperature difference refers to the difference between the adjacent ambient temperatures collected. In the low-temperature range, if the temperature difference is greater than or equal to the first temperature difference, it is considered that the temperature difference is large; otherwise, it is small. In the medium-temperature range and the high-temperature range, if the temperature difference is greater than or equal to the second temperature difference, it is considered that the temperature difference is large; otherwise, it is small.

[0116] Among them, the first temperature difference and the second temperature difference can be determined by the following formula:

[0117] P1 = (x - 10) × 0.01 + 4

[0118] P2 = (x - 10) × 0.01 + 3.2

[0119] Among them, P1 is the first temperature difference and P2 is the second temperature difference.

[0120] Exemplarily, assuming that the indoor ambient temperature (i.e., the initial ambient temperature in the cooking area) is 20°C and the stir-frying seafood working condition is adopted, the cooking curve corresponding to this cooking condition can be Figure 3 represented.

[0121] Figure 3 is another schematic diagram of the cooking curve provided by the embodiment of the present disclosure. AsFigure 3 As shown, the horizontal axis of the cooking curve is the temperature of the cooking area (unit: °C), and the vertical axis is the time (unit: second). In this cooking curve, when the oil is hot, the detected ambient temperature of the cooking area increases by about 40 °C compared to the initial ambient temperature (judged as the oil being hot); when the vegetables are put in at 15:32:30, the temperature drops suddenly by about 7 °C within 1 second, and it is judged that the range hood should be raised to the stir-fry gear.

[0122] Based on the above experimental data, it can be known that by comparing the difference between the ambient temperature of the cooking area and the initial ambient temperature, the current temperature range (low temperature range, medium temperature range or high temperature) can be judged, and the temperature difference (large or small) and the temperature change trend between the ambient temperature in the current second and the ambient temperature in the previous second can be calculated. The above data is matched with multiple preset gear adjustment conditions to determine the target preset gear adjustment condition obtained by matching, so as to judge the current user's cooking behavior and the gear of the range hood suitable for this cooking behavior.

[0123] Exemplarily, the preset gear adjustment conditions determined according to the cooking experimental data can be represented by Table 1.

[0124] Table 1 Filing condition Temperature range Temperature change trend Temperature difference Adjusting wind speed Judging cooking behavior C1 Low temperature range ↓↑ Small Gentle speed Steaming C2 Low temperature range ↓ Large High speed Adding water to cool down C3 Low temperature range ↑ Large High speed Opening the lid to check C4 Medium temperature range ↓↑ Small High speed / Gentle speed Stir-frying / Steaming C5 Medium temperature range ↓ Large High speed Putting in the vegetables C6 Medium temperature range ↑ Large High speed Opening the lid to check C7 High temperature range ↓↑ Small High speed Stir-frying C8 High temperature range ↓ Large Stir-frying quickly Putting in the vegetables C9 High temperature range ↑ Large High speed Oil is hot

[0125] Exemplarily, based on the content shown in Table 1, the process of gear adjustment will be illustrated by two specific examples below.

[0126] Example 1. Assume that the current gear is the low gear. When the target gear determined according to Table 1 is the high gear, that is, the gear of the range hood needs to be adjusted upward, then directly control the range hood to be adjusted from the low gear to the high gear.

[0127] Example 2. Assume that the current gear is the high gear (such as stir-fry). When the target gear determined according to Table 1 is the low gear (high speed or soft speed), that is, the gear of the range hood needs to be adjusted downward. At this time, it is necessary to control the range hood to run at the stir-fry gear for a period of time, such as 100 seconds. During these 100 seconds, no judgment on whether the gear needs to be adjusted is made, and the judgment is made again after 100 seconds. In this way, it can effectively ensure that the existing oil fume is discharged as clean as possible.

[0128] After 100 seconds, the ambient temperature of the cooking area is collected again, and based on the multiple ambient temperatures collected again, the temperature change information of the cooking area is determined. Based on this ambient change information and Table 1, the new target gear to be adjusted is rejudged.

[0129] At this time, there are the following three situations:

[0130] Situation 1. Assume that the target gear is high speed, then directly adjust the gear of the range hood to high speed.

[0131] Case 2: Assume the target gear is high heat stir-fry. Then adjust the suction range hood to the high speed to avoid the bad noise experience brought to the user by the suction range hood staying at the high heat stir-fry gear for a long time.

[0132] Case 3: Assume the target gear is gentle speed. Then adjust the suction range hood to the high speed. When adjusting the suction range hood to a lower gear, do not skip gears to avoid the small gears being unable to exhaust the oil fumes generated by the current cooking behavior and the oil fumes left over from the previous cooking behavior.

[0133] After adjusting the suction range hood according to any of the above cases, it is necessary to control the suction range hood to run at the adjusted gear for a period of time (e.g., 30 seconds), then re-collect the ambient temperature of the cooking area, and determine the temperature change information of the cooking area based on the re-collected ambient temperatures. Based on this ambient change information and Table 1, re-judge the new target preset gear adjustment conditions that are met.

[0134] At this time, there are the following four cases:

[0135] Case 1: Assume the new target preset gear adjustment condition is C1. Then adjust the suction range hood to the gentle speed corresponding to C1.

[0136] Case 2: Assume the new target preset gear adjustment condition is C8. Then adjust the suction range hood to the high heat stir-fry corresponding to C8.

[0137] Case 3: Assume the new target preset gear adjustment conditions are C2, C3, C5, C6, C7 or C9. Then adjust the suction range hood to the gentle speed to avoid the bad noise experience brought to the user by staying at the high speed gear for a long time.

[0138] Case 4: Assume the new target preset gear adjustment condition is C4. Then adjust the suction range hood to the gentle speed. After that, it is necessary to control the suction range hood to run at the gentle speed for a period of time, e.g., 1 minute. (Since the cooking behavior corresponding to C4 is stir-frying or steaming, the continuous running time can be a bit longer compared to other preset gear adjustment conditions). During the 1-minute running, continue to collect the ambient temperature of the cooking area, and judge whether other preset gear adjustment conditions are met based on the collected ambient temperatures. If C5 is met, since the cooking behavior corresponding to C5 is putting in the vegetables and some smoke will be generated when putting in the vegetables, it is necessary to re-time; if C2, C3, C6, C7 or C9 are met, do not re-time. After 1 minute, if other preset gear adjustment conditions except C4 are met, control the suction range hood to adjust to the gear corresponding to the preset gear adjustment condition. If C4 is met, it is considered to be in the stewing state. After the oil fumes are exhausted in the stewing state, the rotation speed needs to be reduced as much as possible to reduce the noise. Then control the suction range hood to adjust to the gentle speed.

[0139] It should be understood that Scenario 4 is the processing procedure when C4 is satisfied for the first time. The first satisfaction means that the target preset gear adjustment condition matched this time is C4 and the target preset gear adjustment condition matched last time is not C4.

[0140] It should be understood that except for Scenario 4, in Scenario 1, Scenario 2, and Scenario 3, after adjusting a gear of the range hood to another gear, it is necessary to control the range hood to operate at the adjusted gear for a period of time (such as 30 seconds), and then re-collect the ambient temperature of the cooking area. Based on the multiple ambient temperatures re-collected, the temperature change information of the cooking area is determined, and based on this ambient change information and Table 1, the new target preset gear adjustment condition that is satisfied is re-judged.

[0141] In summary, the gear adjustment method of the range hood provided by the present disclosure determines the temperature change situation of the cooking area by collecting the temperature of the cooking area at a high frequency and processing the collected ambient temperature, so as to determine the corresponding cooking behavior at this time and the gear that the range hood needs to adjust according to the temperature change situation. This technical solution is not picky about cookware or stoves. During cooking, it can accurately identify cooking behaviors with large amounts of smoke such as oil heating, stir-frying, adding water, and opening the lid to check, automatically increase the air volume to achieve "clean suction", and can also automatically reduce the air volume during cooking behaviors with stable smoke such as steaming to achieve "quiet suction". At the same time, the user can achieve zero manual operation of the range hood throughout the cooking process, with high intelligence and good user experience. Since each preset gear adjustment condition in the present disclosure is determined based on a large amount of cooking experiment data, when adjusting the gear according to the preset gear adjustment condition, the influence of the current cooking behavior and the previous cooking behavior on the oil fume volume is fully considered, and the adjustment accuracy is relatively high, avoiding the situation of false triggering or incorrect gear adjustment.
