[0043] At present, traditional range hoods cannot automatically switch gears and require users to manually switch gears. However, users often do not have time to switch gears when cooking. When using an inappropriate gear to absorb oil fumes, it will lead to incomplete oil fumes, oil fumes spreading throughout the room, noise interference from the range hood, power consumption, and accelerated aging of the range hood.

[0044] To this end, the present application provides a range hood control method, which specifically includes: obtaining first temperature information located in a preset area of ​​the range hood, the first temperature information including at least one of a temperature mutation amount, a relative temperature, a temperature change rate, and a temperature fluctuation value; determining the current cooking scene based on the first temperature information; and controlling the working mode of the range hood based on the current cooking scene. The present application first obtains the first temperature information located in a preset area of ​​the range hood, and determines the current cooking scene through the first temperature information, and then controls the range hood to operate in a corresponding working mode according to the current cooking scene, and can timely control the range hood to switch to a suitable smoking gear according to the current cooking scene, avoiding the occurrence of oil smoke not being completely sucked out, oil smoke spreading throughout the room, excessive noise from the range hood, or energy waste due to inappropriate smoking gear of the range hood, thereby improving the user experience.

[0045] See attached Figure 1 , Figure 1 It is a flowchart of the main steps of a range hood control method according to an embodiment of the present application.

[0046] like Figure 1 As shown, the range hood control method in the embodiment of the present application mainly includes the following steps S101 to S103.

[0047] Step S101: obtaining first temperature information in a preset area of ​​the range hood, wherein the first temperature information includes at least one of a temperature mutation amount, a relative temperature, a temperature change rate and a temperature fluctuation value.

[0048] The preset area of ​​the range hood may be a collection area below the range hood including stoves and pots.

[0049] Specifically, obtaining the first temperature information is to use a temperature sensor to collect the temperature value of the preset area, and obtain at least one of the temperature mutation amount, relative temperature, temperature change rate and temperature fluctuation value of the preset area according to the collected temperature value. The temperature mutation amount can be the temperature difference value after a sudden drop or rise in temperature, the relative temperature can be the temperature difference value between the temperature of the preset area and the temperature of the preset area when the stove is not turned on, the temperature change rate can be the change rate of the temperature value relative to time, and the temperature fluctuation value can be the average value of the change of the temperature value within a certain period of time.

[0050] Step S102: determining a current cooking scene based on the first temperature information.

[0051] The current cooking scene is the cooking stage that the user is currently performing during the cooking process, for example, adding water to the pot to cool it down, opening the lid to check on the pot, or stir-frying at high temperature.

[0052] Step S103: controlling the working mode of the range hood based on the current cooking scene.

[0053] Based on the above steps S101-S103, the present application first obtains the first temperature information located in the preset area of ​​the range hood, and determines the current cooking scene through the first temperature information, and then controls the range hood to operate in the corresponding working mode according to the current cooking scene. The range hood can be controlled to switch to a suitable smoking gear in time according to the current cooking scene, thereby avoiding the occurrence of situations such as incomplete fumes being sucked out, fumes spreading throughout the room, excessive noise from the range hood, or energy waste due to inappropriate smoking gear of the range hood, thereby improving the user experience.

[0054] The above steps S101 to S103 are further explained below.

[0055] With respect to step S101, first temperature information located in a preset area of ​​the range hood is obtained, wherein the first temperature information includes at least one of a temperature mutation amount, a relative temperature, a temperature change rate, and a temperature fluctuation value.

[0056] In one embodiment, a temperature sensor is provided on the range hood, and the temperature sensor is used to collect temperature information located in a preset area of ​​the range hood. The obtaining of the first temperature information includes: obtaining second temperature information collected by the temperature sensor; and determining the first temperature information based on the second temperature information.

[0057] In this embodiment, the temperature sensor may be a non-contact temperature sensor, and the temperature sensor collects second temperature information located in a preset area of ​​the range hood, and determines the first temperature information according to the second temperature information.

[0058] In one embodiment, the second temperature information includes multiple temperature values, and determining the first temperature information based on the second temperature information includes: obtaining a maximum temperature value and a minimum temperature value from the multiple temperature values; obtaining timestamps of the maximum temperature value and the minimum temperature value, respectively; and determining the temperature mutation amount based on the timestamp, the maximum temperature value, the minimum temperature value and the current time.

[0059] Specifically, the temperature sensor collects the temperature value located in the preset area of ​​the range hood according to a preset time interval, and the second temperature information includes multiple temperature values ​​collected by the temperature sensor, for example, 10 temperature values. There is no specific limit on the number of temperature values ​​collected by the temperature sensor, but the more temperature values ​​collected by the temperature sensor, the more accurate the temperature mutation amount. When determining the temperature mutation amount of the first temperature information through the second temperature information, first determine the minimum temperature value and the maximum temperature value among the multiple temperature values ​​collected, and obtain the collection time of the minimum temperature value and the maximum temperature value, and then, according to the difference between the collection time of the temperature value and the current time, subtract the temperature value that is closer to the current time from the temperature value that is farther from the current time, and use the calculated difference as the temperature mutation amount.

[0060] In one embodiment, the second temperature information includes multiple temperature values, and determining the first temperature information based on the second temperature information includes: obtaining an initial temperature value located in a preset area of ​​the range hood; respectively calculating the difference between each temperature value in the second temperature information and the initial temperature value; and determining the relative temperature based on the maximum value of the differences.

[0061] Specifically, the second temperature information includes multiple temperature values ​​collected by the temperature sensor, for example, 10 temperature values. There is no specific limit on the number of temperature values ​​collected by the temperature sensor, but the more temperature values ​​collected by the temperature sensor, the more favorable it is to improve the accuracy of the relative temperature. When determining the relative temperature of the first temperature information through the second temperature information, first obtain the initial temperature value of the preset area of ​​the range hood, the initial temperature value is the initial temperature of the preset area of ​​the range hood before the cooker is turned on, and then calculate the difference between each temperature value in the second temperature information and the initial temperature value, and take the maximum value of the calculated multiple temperature differences as the relative temperature.

[0062] In one embodiment, the second temperature information includes multiple temperature values, and determining the first temperature information based on the second temperature information includes: performing linear fitting on the second temperature information to obtain a corresponding relationship between temperature values ​​and time; and determining a temperature change rate based on the corresponding relationship between the temperature values ​​and time.

[0063] Specifically, the second temperature information includes multiple temperature values ​​collected by the temperature sensor, for example, 20 temperature values. There is no specific limit on the number of temperature values ​​collected by the temperature sensor, but the more temperature values ​​collected by the temperature sensor, the more accurate the temperature change rate. When determining the temperature change rate of the first temperature information through the second temperature information, firstly, linear fitting is performed on the multiple temperature values ​​in the second temperature information to obtain the corresponding relationship between the temperature value and the time, and then the temperature change slope is determined based on the corresponding relationship between the temperature value and the time, and the temperature change rate is determined based on the temperature change slope.

[0064] In one embodiment, the multiple temperature values ​​are 100 temperature values, and every 20 consecutive temperature values ​​in the multiple temperature values ​​are taken as a group, and five groups of temperature values ​​are determined for linear fitting to obtain the correspondence between the five groups of temperature values ​​and time. Five temperature change slopes are determined based on the correspondence between the five groups of temperature values ​​and time, and the minimum slope or the temperature change slope closest to the current time is selected from the five temperature change slopes as the temperature change rate.

[0065] In one embodiment, the second temperature information includes multiple temperature values, and determining the first temperature information based on the second temperature information includes: performing linear fitting on the second temperature information to obtain the corresponding relationship between the temperature value and time; determining the average deviation value of the second temperature information based on each temperature value in the second temperature information and the corresponding relationship between the temperature value and time; and determining the temperature fluctuation value based on the average deviation value.

[0066] Specifically, the second temperature information includes multiple temperature values ​​collected by the temperature sensor, for example, 20 temperature values. There is no specific limit on the number of temperature values ​​collected by the temperature sensor, but the more temperature values ​​collected by the temperature sensor, the more accurate the temperature fluctuation value. When determining the temperature fluctuation value of the first temperature information through the second temperature information, firstly, linear fitting is performed on the multiple temperature values ​​in the second temperature information to obtain the corresponding relationship between the temperature value and time, that is, the curve of the temperature value and time. Then, in the coordinate system of the curve of the temperature value and time, the coordinate point of each temperature value in the second temperature information is determined. In the coordinate system, the horizontal coordinate is time and the vertical coordinate is temperature. The difference between the vertical coordinate of each temperature value and the vertical coordinate of the time corresponding to the curve is calculated respectively. Finally, the average deviation value of the second temperature information is determined according to the average value of all the differences, and the average deviation value is used as the temperature fluctuation value.

[0067] The above is the description of step S101 , and the following is a further description of step S102 .

[0068] With respect to step S102, determining the current cooking scene based on the first temperature information includes: matching the first temperature information with preset scene temperature information, and determining the current cooking scene based on the matching result, wherein each preset scene temperature information corresponds to a current cooking scene.

[0069] In a specific embodiment of the present application, taking the first temperature information including temperature mutation amount, relative temperature, temperature change rate and temperature fluctuation value as an example, the temperature mutation amount ST, relative temperature D, temperature change rate S, and temperature fluctuation value F in the first temperature information are matched with the preset scene temperature information, and the user's current cooking scene is determined according to the matching result. The current cooking scene can be at least one of a low-temperature steaming scene, a water-adding cooling scene, a pot lid opening scene, a low-temperature stir-frying scene, a dish-adding scene, a hot oil scene, a high-temperature stir-frying scene, an oil overheating scene, a pot lid closing scene, and a frying scene. The preset scene temperature information is shown in Table 1.

[0070] Table 1 Preset scene temperature information table

[0071]

[0072]

[0073] In the above table, BG in the dish-serving scenario is the initial temperature value. The values ​​of each threshold in the above table are shown in Table 2 below.

[0074] Table 2 Temperature threshold information table

[0075]

[0076] In a specific embodiment, when matching the first temperature information with the preset scene temperature information, the temperature mutation amount is matched first. If the temperature mutation amount satisfies, the relative temperature, temperature change rate, and temperature fluctuation value are matched.

[0077] For example, when the temperature mutation amount ST is 4, the relative temperature D is 22, the temperature change rate S is 0.13, and the temperature fluctuation value F is 0.2, the temperature mutation amount is first matched with the preset scene temperature information. The temperature mutation amount ST is greater than ST2 (3), and it is matched to the open lid to check scene, the hot oil scene, and the overheated oil scene. Then the relative temperature D is matched with the relative temperatures of these three scenes. The relative temperature D is 22, which is greater than D3 (20) and less than D4 (30), and it is matched to the hot oil scene. The temperature change rate S is matched with the temperature change rate of the hot oil scene. The temperature change rate S is 0.13, which is greater than S7 (0.1), and it is determined that the current cooking scene is the hot oil scene.

[0078] The present application identifies the user's current cooking scene from four analysis dimensions, and then can control the range hood to operate in an appropriate working mode according to the determined cooking scene, to avoid using a lower smoking gear in cooking scenes with a lot of oil smoke, such as frying scenes, which causes oil smoke to spread in the room and affect the user's experience; or, in cooking scenes with less oil smoke, such as low-temperature steaming scenes, using a higher smoking gear, which wastes energy.

[0079] The above is the description of step S102 , and the following is a further description of step S103 .

[0080] With respect to step S103, controlling the working mode of the range hood based on the current cooking scene includes: controlling the range hood to operate in any one working mode of a soft speed mode, a high speed mode, and a stir-fry mode based on the current cooking scene.

[0081] Specifically, according to the determined correspondence between the current cooking scene and the preset cooking scene and the working mode, the range hood is controlled to operate in any one of the working modes: soft speed mode, high speed mode, and stir-fry mode. The correspondence between the cooking scene and the working mode is shown in Table 3.

[0082] Table 3 Correspondence between cooking scenes and working modes

[0083]

[0084]

[0085] The present application controls the range hood to operate in a corresponding working mode according to different cooking scenarios, and can timely adopt the appropriate smoking gear of the range hood according to the cooking scenario, thereby avoiding the occurrence of situations such as incomplete fumes being sucked out, fumes spreading throughout the room, excessive noise from the range hood, or energy waste due to inappropriate smoking gear of the range hood, thereby improving the user experience.
