Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention provides an application scene of a range hood. As shown in fig. 1, the application scenario includes the following elements: a range hood 11, a kitchen range 12, a vegetable washing table 13, a window 14 and a dining table 15. The range hood 11 is provided with a panoramic camera capable of shooting an image of a target area within a preset range centered on the cooker 12. When a user cooks on the cooker 12, the cooker 12 generates oil smoke, and when the oil smoke starts to generate, the user forgets to turn on the range hood, and only realizes to turn on the range hood when the concentration of the oil smoke is too high to choke the nose.
Referring to fig. 2, fig. 2 is a schematic flow chart of a range hood control method according to an embodiment of the present invention. The method comprises the following steps:
and 21, determining the oil smoke concentration of the target area when detecting that the user exists in the target area.
The target area in the embodiment of the invention is used for describing the coverage area of the oil smoke when the user cooks. The current oil smoke condition can be calculated by judging the oil smoke concentration in the target area. The selection of the target region may be customized by the user, and the area of the target region may be of any size. For example, the target area may be an area of the entire kitchen or a certain area around the range hood.
In the embodiment of the invention, the user in the target area can be detected in any suitable detection mode to determine whether the user exists. For example, using an infrared human body sensor or a sound sensor, it is determined whether a user is present in the target area.
After the user is present, it can trigger the range hood to further determine the soot concentration in the target area. It may specifically employ any suitable sensing device to determine the soot concentration in the target area. For example, a sensing device such as a gas sensor or an ultrasonic sensor is used.
And step 22, when the oil smoke concentration is greater than a preset oil smoke concentration threshold value, sending a starting instruction to the range hood so that the range hood is started according to the starting instruction.
In this embodiment, an oil smoke concentration threshold value can be preset, and when the detected oil smoke concentration is greater than the preset oil smoke concentration threshold value, an opening instruction is sent to the range hood, so that the range hood is intelligently opened according to the opening instruction.
The preset oil smoke concentration threshold value can be the lowest oil smoke concentration acceptable by a user and is determined by specific practical conditions. The opening mode of the intelligent range hood is humanized, and the power consumption of the range hood is reduced.
The range hood provided by the embodiment of the invention can intelligently control the starting of the range hood according to whether a user exists in the target area or not and the concentration of oil smoke in the target area, so that the intelligent control of the range hood is realized, the phenomenon that the user is choked because the user forgets to start the range hood when cooking is avoided, and the use of the user is facilitated.
In some embodiments, it is specifically determined whether the detection of the user and the smoke concentration exist in the target area through the image acquired by the image acquisition device, and fig. 3 is a flowchart of a method of controlling the smoke ventilator according to an embodiment of the present invention. As shown in fig. 3, the method includes:
and 31, acquiring an oil smoke image of the target area.
Specifically, the oil smoke image can be collected in a photographing or video recording mode. The soot image may be a photographed image at a specific angle in the target area. A cooktop or other fume generating source may be included within the image.
And step 32, judging whether a user exists in the oil smoke image, and if so, determining the oil smoke concentration of the target area from the oil smoke image.
The range hood collects human body features such as human faces and the like in advance, and the collected features are stored in a sample space as feature samples. The mode of determining whether the user exists from the oil smoke image is as follows: and comparing the user characteristics in the extracted oil smoke image with the characteristic samples stored in the sample space, and determining that the user exists under the condition of successful comparison.
And step 33, when the oil smoke concentration is greater than the preset concentration threshold value, sending a starting instruction to the range hood so that the range hood is started according to the starting instruction.
The range hood stores oil smoke images with different concentrations as samples in advance, and compares the collected oil smoke images with the oil smoke images with different concentrations in the sample library to determine the concentration of oil smoke.
Because different users have different degrees of sensitivity to oil smoke. Therefore, in order to further improve the intelligent degree of the range hood, in some embodiments, when the range hood determines that the user exists according to the oil smoke image, the range hood can further determine the user category, and intelligently turn on the range hood according to the user category.
Fig. 4 is a schematic flow chart of a range hood control method according to another embodiment of the present invention. As shown in fig. 4, the method includes:
and step 41, acquiring an oil smoke image of the target area.
And 42, judging whether a user exists in the oil smoke image, and if so, determining the oil smoke concentration of the target area from the oil smoke image.
Step 43, determining the user category of the user in the oil smoke image, wherein the user category at least comprises: the elderly, young and children.
Specifically, the identification of the elderly, the young and the children may be performed by extracting face features of the user, and searching for a category to which the user belongs according to comparison between the face features and features stored in the sample space.
The determination of the user category may be that the sample space stores face features of a specific user in advance, for example, the face features of all users who cook frequently, and the range hood compares the face features in the extracted oil smoke image with the face features in the sample space to determine the user category; or in a networking mode, comparing the extracted face features in the oil smoke image with the face features in the cloud storage library to determine the age of the user, and determining the category of the user according to the age. In the first method, the features of the user may not be stored in the sample space in advance, which may result in the situation that the features cannot be recognized.
And step 44, determining the initial air draft speed corresponding to the user category.
The initial air draft speed is the air draft speed when the range hood is opened. Different user's classification corresponds different initial convulsions speed, for example, because old person and children compare the young to the oil smoke more sensitive, then initial convulsions speed when the user is the young can be less than the initial convulsions speed of user when being old person and children. It should be noted that, if the category of the user in step 43 is the category of the preset mode, the initial air draft speed corresponding to the category of the preset mode is also the preset initial air draft speed.
And step 45, when the oil smoke concentration is greater than a preset oil smoke concentration threshold value, sending an opening instruction to the range hood so that the range hood is opened according to the initial air draft speed.
Sometimes, during the cooking process, other related users may learn to watch by the user, so as to avoid that other related users are choked by cooking oil while watching the cooking, and in some embodiments, some reminding steps may be further performed to avoid such a problem. Fig. 5 is a schematic flow chart of a range hood control method according to another embodiment of the present invention. As shown in fig. 5, the method includes the steps of:
and 51, acquiring a lampblack image of the target area.
And step 52, judging whether a user exists in the oil smoke image, and if so, determining the oil smoke concentration of the target area from the oil smoke image.
And step 53, determining the number of users in the oil smoke image.
And step 54, when at least two users exist in the oil smoke image, forming an illumination area which takes the kitchen range positioned below the range hood as a central point, wherein the area of the illumination area is in positive correlation with the oil smoke concentration.
In an embodiment of the present invention, the illumination area is used to prompt other relevant users not performing cooking activities to stand outside the illumination area, so as to prevent accidental injury by oil smoke.
And step 55, when the concentration of the oil smoke is greater than a preset concentration threshold value, sending a starting instruction to the range hood so that the range hood is started according to the starting instruction.
And 56, when the concentration of the oil smoke changes, sending an adjusting instruction to the range hood so that the range hood can adjust the air draft speed of the range hood according to the adjusting instruction.
Wherein, the lampblack absorber can be in advance to the oil smoke of different concentrations grade, is in the oil smoke concentration of different grades, corresponds the convulsions speed of different grades, according to the oil smoke concentration of confirming, can confirm the convulsions speed that corresponds with this oil smoke concentration.
It should be noted that, after the lampblack absorber is opened according to initial exhaust speed, the user cooks, the lampblack absorber not only according to the exhaust speed of the intelligent adjustment lampblack absorber of oil smoke content that detects, can also adjust the angle of smoking of lampblack absorber, for example, the lampblack absorber is at the air exhaust in-process, can be self-adaptive turn to the culinary art user with the angle of smoking, make the regional oil smoke volume at culinary art user place less, the user can normally accomplish the culinary art activity, through the above-mentioned mode, can make the exhaust speed and the angle of smoking of lampblack absorber more humanized, can adapt to different culinary art users. Of course, in other alternative embodiments, the range hood can also work according to the preset initial air draft speed when opening, thereby realizing the intelligent and manual dual control of the range hood.
Through the oil smoke image of discernment during different culinary art environment to confirm the oil smoke concentration according to the oil smoke image, confirm the exhaust speed of lampblack absorber according to the oil smoke concentration, make whole process all not need the exhaust speed of user manual regulation lampblack absorber, realize the intelligent operation of lampblack absorber.
Further, in the embodiment of the invention, the range hood can be automatically and intelligently turned off under a specific condition. For example, when the cooking range is detected to be in a closed state, the oil smoke concentration is lower than a preset threshold value, and no user exists in a target area, the range hood is automatically closed.
The range hood control method provided by the embodiment of the invention can be intelligently opened and closed according to users and oil smoke concentration. Meanwhile, the range hood can select different opening modes according to different user categories in a self-adaptive manner, humanization of the range hood is achieved, the exhaust speed of the range hood can be adjusted in real time according to different oil smoke concentrations generated in the cooking process in the working process of the range hood, and the range hood is convenient for users to use.
The range hood does not need manual control of a user in the whole process from starting to finishing the work, so that the method can realize full-automatic intellectualization of the range hood and has good user experience.
