[0028] Figure 1 is a schematic structural diagram of a range hood provided according to an exemplary embodiment. Figure 1As shown, a range hood is provided in an embodiment of the present specification, which includes a window and a sensing device. Optionally, the sensing device may include an infrared sensor and other devices with information collection function; specifically, the sensing device is installed in the window, and the basic information of the window such as shape and size is basically the same as the basic information of the sensing device such as shape and size, and the sensing device can be completely installed on the window; optionally, multiple windows can be provided on the range hood to install the sensing device. Specifically, the multiple windows on the range hood are arranged in a straight line, and the distance between any two windows is the same. Specifically, two windows are used in the present application, and two sensing devices are installed to implement the stove control method in the present application. Specifically, the sensing device used in the present application is an infrared sensor.

[0029] Specifically, the range hood also includes a palmprint recognition device. Optionally, the palmprint recognition device may include a device with a palmprint recognition function such as a palmprint recognizer. Optionally, a palmprint recognition device may be set at horizontal positions corresponding to multiple windows. Specifically, it may be set at horizontal positions such as the outside and inside of the window to obtain and enter palmprint information of adult users. Optionally, adult users may enter the palmprint storage function, turn on the palmprint recognition function and turn off the palmprint recognition function through buttons on the palmprint recognition device or mobile phone software.

[0030] Specifically, the range hood also includes a visual interface and a voice device. Optionally, the visual interface is used to display the prompt information of the range hood, and the voice device is used to broadcast the prompt information of the range hood. Specifically, the voice device may include a speaker and other devices with sound broadcasting function.

[0031] Figure 2 1 is a schematic diagram of a method for controlling a stove according to an exemplary embodiment. In an optional embodiment, the controller of the range hood is used as the execution body in the present invention to introduce an embodiment of a method for controlling a stove of the present application, such as Figure 2 As shown, the above method may include:

[0032] S201: Obtaining the waving duration of the target object and the occlusion durations of multiple windows.

[0033] In a specific embodiment, the waving duration can be the duration of the target object waving within a preset waving distance; the preset waving distance can be the distance between edge windows in multiple windows; specifically, the preset waving distance is determined based on the edge point in the edge window; the multiple window occlusion duration can be the corresponding duration of each window being occluded by the hand during the target object's waving process; the target object can be a person with the waving function.

[0034] Specifically, when the stove is turned on, the stove will automatically send a message to the range hood indicating that the stove is turned on. Correspondingly, after receiving the message indication that the stove is turned on, the range hood will display a prompt message on the visual interface of the range hood that the target object needs to wave. Correspondingly, the controller of the range hood will also control the voice device to broadcast the prompt message for the target object to wave.

[0035] Optionally, when the target object waves, the sensor device on the range hood captures the waving duration of the target object and the occlusion duration of multiple windows. Optionally, when the target object waves, the waving distance is uncertain, and there may be a situation where the waving distance exceeds the preset waving distance. Therefore, when the target object is waving, the sensor device captures the waving duration within the preset waving distance. Optionally, when the target object waves past the window, the sensor device installed on the window will generate a corresponding waveform when it is blocked by the target object's hand. The window occlusion duration can be specifically reflected as the cumulative time of the waveform when the target object blocks the window by waving.

[0036] S203: Determine the hand widths of multiple target objects based on the waving duration, the multiple window occlusion durations, and the preset waving distance.

[0037] In a specific embodiment, the target object hand width can be the hand width of the target object; specifically, when the sensor device in the range hood obtains the waving duration and the multiple window occlusion durations, it will transmit the waving duration and the multiple window occlusion durations to the controller in the range hood, and accordingly, the controller will call the pre-stored preset waving distance. Further, the controller in the range hood calculates the hand widths of multiple target objects based on the waving duration, the multiple window occlusion durations and the preset waving distance. Accordingly, based on the waving duration, the preset waving distance and the window occlusion duration corresponding to each window in the multiple windows on the range hood, the target object hand width corresponding to each window is calculated.

[0038] Figure 3 FIG. 1 is a flow chart of determining the hand widths of multiple target objects according to an exemplary embodiment. In an optional embodiment, Figure 3 As shown, based on the waving duration, the multiple window blocking durations, and the preset waving distance, determining the hand widths of multiple target objects may include:

[0039] S301: Determine a waving motion speed based on a preset waving distance and waving duration;

[0040] S303: Determine the hand widths of multiple target objects based on the waving motion speed and the occlusion durations of multiple windows.

[0041] In a specific embodiment, the waving motion speed may be the speed at which the target object waves per unit time;

[0042] Specifically, the controller of the range hood divides the acquired waving duration and the called preset waving distance to determine the waving movement speed. Specifically, the formula Specifically, A represents the preset waving distance, B represents the waving duration, and V represents the waving movement speed;

[0043] Furthermore, when the controller of the range hood calculates the waving motion speed, it multiplies the waving motion speed and the window occlusion duration corresponding to each window, and accordingly determines the target object hand width corresponding to each window, that is, multiple target object hand widths. Specifically, it can be determined according to the formula S=C×V, specifically, C represents the window occlusion duration, and S represents the target object hand width.

[0044] In the above embodiment, the waving movement speed is calculated by the waving duration and the preset waving distance, and then the hand widths of multiple target objects are calculated by the calculated waving movement speed and the occlusion durations of multiple windows, thereby improving the accuracy and real-time performance of determining the hand widths of the target objects, and further improving the accuracy and real-time performance of stove control.

[0045] S205: Determine a hand width comparison result based on the hand widths of multiple target objects and a preset hand width threshold; and control the cooker to be turned off if the hand width comparison result indicates that a preset condition is met.

[0046] In a specific embodiment, the hand widths of adults and children are different. Generally, the hand widths of adults are larger than those of children. The present application utilizes the judgment condition that the hand widths of adults are larger than those of children. When a child accidentally triggers the stove, the range hood controller is used to control the stove to be turned off, thereby protecting the safety of the children.

[0047] In a specific embodiment, the preset hand width threshold may be a standard hand width value for an adult; the hand width comparison result may be used to indicate whether a preset condition is met, and optionally, the preset condition may be that the minimum hand width of a target object among multiple hand widths of target objects is smaller than the preset hand width threshold;

[0048] Specifically, when the controller of the range hood calculates the hand widths of multiple target objects, it calls a pre-stored preset hand width threshold, and compares the hand widths of the multiple target objects with the preset hand width threshold, and then determines the hand width comparison result. Furthermore, when the hand width comparison result indicates that the preset conditions are met, the controller of the range hood controls the stove to turn off. Specifically, the controller of the range hood sends a stove-off information to the stove, and correspondingly, the stove turns off the stove when receiving the stove-off information.

[0049] Figure 4is a flowchart of determining that the hand width comparison result indicates that the minimum hand width of the target object is less than a preset hand width threshold according to an exemplary embodiment. In an optional embodiment, if Figure 4 As shown, based on the hand widths of multiple target objects and a preset hand width threshold, determining the hand width comparison result may include:

[0050] S401: sorting the hand widths of multiple target objects based on their hand widths, and determining the minimum hand width of the target object;

[0051] S403: When the minimum target object hand width is less than a preset hand width threshold, determine that the hand width comparison result indicates that a preset condition is met, and control the visual screen of the range hood to display that the child protection function is turned on.

[0052] In a specific embodiment, the controller of the range hood, after calculating multiple target object hand widths, sorts the multiple target object hand widths by size, and accordingly, the minimum target object hand width can be determined. Further, after determining the minimum target object hand width, the controller of the range hood compares the minimum target object hand width with a preset hand width threshold to determine the hand width comparison result. Accordingly, when the minimum target object hand width is less than the preset hand width threshold, the hand width comparison result indicates that the preset conditions are met. Further, the controller of the range hood controls the cooker to turn off, and controls the visual interface of the range hood to display that the child protection function is turned on.

[0053] In the above embodiment, the hand widths of the target objects are sorted, and then the hand width comparison result is determined by comparing the minimum target object hand width with a preset hand width threshold, thereby reducing the complexity of determining the hand width comparison result. Furthermore, when the hand width comparison result indicates that the preset conditions are met, the stove is controlled to be turned off, thereby reducing the complexity and rationality of the stove shutdown control.

[0054] In an optional embodiment, the above method may further include:

[0055] When the minimum target object hand width is not less than a preset hand width threshold, it is determined that the hand width comparison result indicates that the preset condition is not met, and the range hood is controlled to be started.

[0056] In a specific embodiment, the controller in the range hood can also determine that the minimum target object hand width is not less than the preset hand width threshold when comparing the minimum target object hand width with the preset hand width threshold, that is, the hand width comparison result indicates that the preset condition is not met. Accordingly, the controller of the range hood controls the range hood to start.

[0057] In the above embodiment, by listing the situations where the hand width comparison result is not satisfied with the preset conditions, the rationality of the technical solution of the present application is improved, and a method for starting the range hood is provided when the cooker is not accidentally triggered by a child.

[0058] Figure 5 1 is a flow chart of controlling the start-up of a range hood when the window blocking time is greater than a first time threshold and less than a second time threshold according to an exemplary embodiment. Figure 5 As shown, when the hand width comparison result indicates that no preset condition is satisfied, the above method may further include:

[0059] S501: Obtaining a first duration threshold, a second duration threshold, a first waving duration threshold, and a second waving duration threshold corresponding to the range hood;

[0060] S503: Compare the occlusion durations of multiple windows with the first duration threshold and the second duration threshold respectively, and compare the waving duration with the first waving duration threshold and the second waving duration threshold respectively, to determine a duration comparison result;

[0061] S505: When the duration comparison result indicates that the durations of multiple window occlusions are greater than the first duration threshold, and the durations of multiple window occlusions are less than the second duration threshold; and the waving duration is less than the first waving duration threshold, and the waving duration is greater than the second waving duration threshold, control the start of the range hood.

[0062] In a specific embodiment, the first duration threshold may be the shortest duration that the hand of the target object should appear in each window during the waving process; the second duration threshold may be the longest duration that the hand of the target object should appear in each window during the waving process; the first waving duration threshold may be the longest total duration that the target object appears within a preset waving distance during the waving process; the second waving duration threshold may be the shortest total duration that the target object appears within a preset waving distance during the waving process;

[0063] Specifically, the first duration threshold, the second duration threshold, the first waving duration threshold and the second waving duration threshold are set by the target object based on actual conditions and stored in the controller of the range hood. Accordingly, when the hand width comparison result indicates that the preset conditions are met, the controller in the range hood calls the pre-stored first duration threshold and the second duration threshold, and compares the obtained multiple window occlusion times with the first duration threshold and the second duration threshold respectively. Accordingly, the controller in the range hood will also call the pre-stored first waving duration threshold, and compare the obtained waving duration with the first waving duration threshold and the second waving duration threshold respectively. Further, a duration comparison result is obtained. Optionally, each of the multiple window occlusion durations is compared with the first duration threshold and the second duration threshold. Accordingly, when the duration comparison result indicates that the multiple window occlusion durations are all greater than the first duration threshold, the multiple window occlusion durations are all less than the second duration threshold, and the waving duration is less than the first waving duration threshold, and the waving duration is greater than the second waving duration threshold, the controller of the range hood controls to start the range hood.

[0064] In the above embodiment, by comparing the blocking durations of multiple windows with the first duration threshold and the second duration threshold respectively, and comparing the waving durations with the first waving duration threshold and the second waving duration threshold respectively, interference caused by the target object waving too slowly or too quickly is eliminated, thereby avoiding false startup and abnormal movements, and further improving the accuracy of controlling the stove to shut down.

[0065] Figure 6 FIG. 1 is a flow chart of controlling the start-up of a range hood based on matching palm print information with preset palm print information according to an exemplary embodiment. Figure 6 As shown, when the duration comparison result indicates that the occlusion durations of multiple windows are all greater than the first duration threshold, the occlusion durations of multiple windows are all less than the second duration threshold, and the waving duration is less than the first waving duration threshold, and the waving duration is greater than the second waving duration threshold, the above method may further include:

[0066] S601: Obtaining palm print information and preset palm print information corresponding to the range hood;

[0067] S603: When the palm print information matches the preset palm print information, control the range hood to start.

[0068] In a specific embodiment, the palm print information may be palm print information of the target object's hand collected by a palm print recognition device; the preset palm print information may be palm print information pre-stored in the range hood; optionally, the preset palm print information is generally palm print information of an adult user.

[0069] Specifically, adult users can enter preset palm print information at any time. Accordingly, adult users can preferentially store their palm print information in the range hood through buttons on the palm print recognition device or mobile phone software. Accordingly, the range hood controller will control the palm print recognition device to obtain the palm print information of the target object while controlling the sensing device to obtain the waving duration and multiple window occlusion durations of the target object. Accordingly, when the duration comparison result indicates that the window occlusion duration is greater than the first duration threshold and less than the second duration threshold, the range hood controller will match the obtained palm print information with the preset palm print information. If the palm print information matches the preset palm print information, the range hood will be controlled to be turned on. If the palm print information does not match the preset palm print information, the cooker will be controlled to be turned off.

[0070] In the above embodiment, when the duration comparison result indicates that the durations of multiple window occlusions are all greater than the first duration threshold and less than the second duration threshold, and the waving duration is less than the first waving duration threshold and the waving duration is greater than the second waving duration threshold, the palm print information of the target object is matched with the preset palm print information, and when the palm print information of the hand matches the preset palm print information, the range hood controller controls to turn on the range hood, thereby improving the rigor and rationality of turning on the range hood, and also improving the safety of children.

[0071] In an optional embodiment, the above method may further include:

[0072] When the duration comparison result indicates that the occlusion duration of any window among multiple window occlusion durations is less than the first duration threshold, or the occlusion duration of any window is greater than the second duration threshold, or the waving duration is greater than the first waving duration threshold, or the waving duration is less than the second waving duration threshold, the range hood is controlled to voice remind the target object to wave twice at a uniform speed, and the waving duration and multiple window occlusion durations are re-obtained.

[0073] In a specific embodiment, when the controller of the range hood compares multiple window occlusion durations with the first duration threshold and the second duration threshold respectively, and compares the waving durations with the first waving duration threshold and the second waving duration threshold respectively, there may be a situation where the duration comparison result indicates that any of the multiple window occlusion durations is less than the first duration threshold, or any of the window occlusion durations is greater than the second duration threshold, or the waving duration is greater than the first waving duration threshold, or the waving duration is less than the second waving duration threshold. In this case, the controller of the range hood will control the voice device of the range hood to voice remind the target object to wave evenly twice, and control the sensor device to re-acquire the waving duration and the window occlusion duration, and then use the re-acquired waving duration and window occlusion duration to calculate the hand width of the target object.

[0074] In the above embodiment, when the duration comparison result indicates that the duration of any window occlusion among multiple window occlusion durations is less than the first duration threshold, or the duration of any window occlusion duration is greater than the second duration threshold, or the waving duration is greater than the first waving duration threshold, or the waving duration is less than the second waving duration threshold, the target object is prompted, thereby improving the accuracy of obtaining the waving duration and multiple window occlusion durations, and further improving the accuracy of calculating the target object's hand width, thereby improving the accuracy of controlling the stove.

[0075] In a specific embodiment, when the range hood obtains information about the stove being turned on, the controller of the range hood controls the voice device to remind the target object to wave, and controls the sensor device on the range hood to obtain the waving duration and the multiple window occlusion durations. Further, the controller of the range hood calculates the hand widths of multiple target objects based on the obtained waving duration, the multiple window occlusion durations and the called preset waving distances, and accordingly sorts the hand widths of the multiple target objects to obtain the minimum hand width of the target object. Further, the hand widths of the multiple target objects are compared with the preset hand width threshold to determine the hand width comparison result. Specifically, the minimum hand width of the target object is compared with the preset hand width threshold. The size of the preset hand width threshold is set, and when the minimum target object hand width is less than the preset hand width threshold, that is, the hand width comparison result indicates that the preset condition is met, the range hood controller controls the cooker to turn off. Optionally, when the minimum target object hand width is not less than the preset hand width threshold, that is, the hand width comparison result indicates that the preset condition is not met, the range hood controller controls the range hood to start. Optionally, when the hand width comparison result indicates that the preset condition is not met, the first duration threshold and the second duration threshold are obtained, and the occlusion durations of multiple windows are compared with the first duration threshold and the second duration threshold respectively, and the waving duration is compared with the first waving duration threshold and the second duration threshold respectively. The second waving time threshold is used to compare the two waving time thresholds to determine the time comparison result. Accordingly, when the time comparison result indicates that the occlusion time of any window among the multiple window occlusion time is less than the first time threshold, or the occlusion time of any window is greater than the second time threshold, or the waving time is greater than the first waving time threshold, the range hood is controlled to voice remind the target object to wave twice at a uniform speed, and the waving time and the multiple window occlusion time are re-acquired. Accordingly, when the time comparison result indicates that the occlusion time of multiple windows is greater than the first time threshold and less than the second time threshold, and the waving time is less than the first waving time threshold, and the waving time is greater than the second waving time threshold, the range hood is controlled to voice remind the target object to wave twice at a uniform speed, and the waving time and the multiple window occlusion time are re-acquired. The controller controls the range hood to start. Optionally, when the duration comparison result indicates that the durations of multiple window occlusions are all greater than a first duration threshold and less than a second duration threshold, and the waving duration is less than the first waving duration threshold, and the waving duration is greater than the second waving duration threshold, the range hood controller will control the palm print information of the target object collected by the palm print recognition device to match the preset palm print information. When the palm print information matches the preset palm print information, the range hood is controlled to start. Through the stove control method of the present application, when a child accidentally triggers the stove, the range hood can be controlled to shut down, thereby improving the safety of children and reducing energy consumption.
