Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and in particular to a control method and control device for a range hood. Background Technology

[0002] Most existing range hood control methods include touch pointing, physical buttons, infrared gesture control, and rotary encoders, which have the following drawbacks: Firstly, users need to use their hands to press or touch the controls, causing kitchen grime from their hands to stick to the range hood. Conversely, grease, dust, and other grime from the range hood also stick to the hands, potentially harming the user's health over time. Secondly, for range hoods with capacitive touch controls, the touch feedback is weak; users need to look up to confirm the button's location and whether it has been successfully triggered.

[0003] While current range hoods offer gesture control, allowing users to control different functions by waving their hands in different areas of the hood (i.e., by placing sensors in different locations), the gesture control method is simplistic and offers limited functionality. Summary of the Invention

Further, the first preset condition includes a first working condition and a second working condition; the step of entering the initial working mode when the limb movement parameters meet the first preset condition includes: determining a first angle between the limb position and the preset limb position when the wearer performs limb movements along the first movement direction within a preset detection time, based on the first movement direction and the preset limb position of the limb movement parameters; if the first angle decreases from greater than a preset first angle to less than a preset second angle within the preset detection time, confirming that the first movement direction meets the first working condition; acquiring the trend of change of the first acceleration, and if the trend of change of the first acceleration meets a first preset trend, confirming that the trend of change of the first acceleration meets the second working condition; entering the initial working mode when it is confirmed that the first movement direction meets the first working condition and the trend of change of the first acceleration meets the second working condition.

[0007] Furthermore, in the initial working mode, if the current limb movement parameters of the wearer are collected and meet the second preset condition, the step of determining the control command based on the current limb movement parameters includes: obtaining the initial limb position of the wearer when no limb movement is made in the initial working mode; monitoring the current limb position of the wearer, and if the current limb position is different from the initial limb position, obtaining the current limb movement parameters; determining the pause time between the current limb movement parameters and the next limb movement parameters, and whether the current limb movement parameters meet the second preset condition; wherein, the second preset condition includes a pause time requirement and a movement parameter requirement; if the pause time does not meet the pause time requirement or the current limb movement parameters do not meet the movement parameter requirement, entering an empty state until the wearer is detected to have returned to the initial limb position; wherein, the empty state represents a state in which the wearable device enters a waiting response and does not respond to any limb movement; if the pause time meets the pause time requirement and the current limb movement parameters meet the movement parameter requirement, the current limb movement parameters are determined as the control command.

If the vertical acceleration trend of the third acceleration meets the second preset acceleration trend and the horizontal acceleration trend meets the third preset acceleration trend, it is confirmed that the third acceleration trend meets the preset third closing condition; wherein, the third acceleration trend includes the vertical acceleration trend and the horizontal acceleration trend; when it is confirmed that the third motion direction meets the preset first closing condition and the third acceleration trend meets the preset third closing condition, the initial working mode is exited.

[0010] Furthermore, the wearable device also includes a light module and a vibration module; the method further includes: when the wearable device enters or exits the initial working mode, controlling the light module to flash according to preset light rules as a reminder, and controlling the vibration module to vibrate according to preset vibration rules as a reminder; in the initial working mode, when the current limb movement parameters meet preset conditions, controlling the light module to flash according to preset light rules as a reminder; in the initial working mode, when the current limb movement parameters do not meet preset conditions, controlling the vibration module to vibrate according to preset vibration rules as a reminder.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To facilitate understanding of this embodiment, the embodiments of the present invention will be described in detail below.

[0032] Example 1:

[0033] Figure 1 This is a flowchart of a control method for a range hood applied to a wearable device, provided in Embodiment 1 of the present invention.

[0034] Reference Figure 1 Control methods for range hoods applied to wearable devices include:

[0035] Step S101: If it is confirmed that a communication connection has been established with the range hood, collect the limb movement parameters of the wearer; the limb movement parameters include the direction of movement and acceleration.

[0036] Here, wearable devices can be well-equipped fitness trackers already on the market, such as Huawei Band, Xiaomi Band, and Apple Watch. Their built-in motion sensors can detect the user's activity level, collecting data on various activities like running, walking, swimming, and fitness. This data analysis can then provide recording and analysis of the user's activity. Based on this, corresponding motion tracking modes or programs can be added to these wearable devices to control the range hood.

[0037] The connection between wearable devices and communication modules can be via Bluetooth, WiFi, or infrared.

[0038] Range hoods can also be used with other kitchen appliances that can communicate with each other.

[0039] Specifically, after the user powers on the range hood, the communication module on the hood is activated. Taking Bluetooth connection and a fitness tracker as an example, the range hood searches for Bluetooth devices and waits to pair with the fitness tracker. The fitness tracker is then activated, receives the Bluetooth pairing request sent by the range hood, and establishes a connection. Each time the fitness tracker sends a control signal to the range hood, it checks whether the Bluetooth connection is active; if it is lost, it re-establishes the connection.

[0040] Step S102: When the limb movement parameters meet the preset conditions, a control command is generated based on the limb movement parameters.

[0041] Specifically, the fitness tracker collects the user's body movements. Taking arm movements as an example: waving the arm upwards turns on the range hood, waving it to the right activates the stir-fry function. Different movements correspond to different functions, achieving the effect of touch button control. Users can use the initially set control actions or define their own. After switching functions with a wave, the fitness tracker emits different light colors to remind the user that the range hood function has been switched; different functions correspond to different light colors. Controlling the range hood through a wearable device avoids the user's contact with the range hood during cooking, reducing cross-infection of bacteria and protecting the user's health. It allows users to focus more on cooking without looking up to check if the range hood function has switched. It also caters to special groups, such as people with dwarfism or wheelchair users, who may have difficulty reaching the range hood, which is suspended high up; by using a wearable control device, they can control the range hood from any location.

[0042] In one embodiment, reference is made to Figure 2 In step S102, the step of generating control commands based on limb movement parameters when the limb movement parameters meet preset conditions includes:

[0043] Step S201: When the limb movement parameters meet the first preset condition, the initial working mode is entered.

[0044] Here, limb movement parameters can be detected and collected by the three-axis motion sensor in the fitness tracker. These parameters include the first direction of arm movement and the trend of the first acceleration change. To prevent interference from other movements during cooking while the user is wearing the fitness tracker, preset limb movement judgment conditions are established.

[0045] In one embodiment, reference is made to Figure 3 In step S201, the step of entering the initial working mode when the limb movement parameters meet the first preset condition includes:

[0046] Step S301: Based on the first direction of movement of the limb movement parameters and the preset limb position, determine the first angle between the limb position and the preset limb position when the user performs limb movements along the first direction of movement within a preset detection time.

[0047] Here, the preset limb position is when the user is wearing the fitness tracker completely horizontally, and the judgment angle at this time is set to 0°. The preset detection time is set to 1 second. The first direction of movement is upward.

[0048] Step S302: If the first included angle decreases from greater than the preset first included angle to less than the preset second included angle within the preset detection time, it is confirmed that the first movement direction meets the first working condition.

[0049] Here, the preset first angle and preset second angle can be set according to the actual situation. The preset first angle can be set to 50° and the preset second angle can be set to 10°. The first working condition is that during the arm movement, the first angle gradually changes from greater than 50° to less than 10° within 1 second.

[0050] Step S303: Obtain the trend of change of the first acceleration. If the trend of change of the first acceleration satisfies the first preset trend, confirm that the trend of change of the first acceleration satisfies the second working condition.

[0051] Here, the first preset acceleration trend in the vertical direction is obtained when the user raises their arm. Based on the motion characteristics of the arm-raising action, during the process of the user raising their arm, the first preset trend is that the horizontal acceleration is almost 0, and the vertical acceleration first changes from 0 to the first preset acceleration, then from the first preset acceleration back to 0, then from 0 to the second preset acceleration, and finally from the second preset acceleration back to 0. The first and second preset accelerations can be set according to actual conditions.

[0052] The second working condition is that during the arm movement, the first acceleration changes from 0 to the first preset acceleration within 1 second, then changes from the first preset acceleration back to 0, then changes from 0 to the second preset acceleration, and finally changes from the second preset acceleration back to 0.

[0053] Specifically, the system is set to enter the initial working mode when the user raises their arm from a natural position to a horizontal position.

[0054] In an ideal scenario, when the arm wearing the fitness tracker is completely horizontal, the judgment angle at this point is set to 0°, confirming this as the preset limb position. The preset detection time is set to 1 second, acquiring the first angle between the user's arm and the preset limb position along the direction of movement. The first preset angle is set to 50°, and the second preset angle is set to 10°. The first working condition is that during arm movement, the first angle gradually changes from greater than 50° to less than 10° within 1 second.

[0055] The system acquires the vertical acceleration of the user's raised arm within a preset detection time. The second working condition is that during the arm movement, the first acceleration changes from 0 to a first preset acceleration within 1 second, then changes from the first preset acceleration back to 0, then changes from 0 to a second preset acceleration, and finally changes from the second preset acceleration back to 0.

[0056] Step S304: When it is confirmed that the first motion direction meets the first working condition and the change trend of the first acceleration meets the second working condition, the initial working mode is entered.

[0057] Specifically, the system is set to enter the initial working mode when the user raises their arm from a natural (hanging) state to a horizontal state.

[0058] Step S202: In the initial working mode, if the current limb movement parameters of the wearer are collected and meet the second preset condition, the control command is determined based on the current limb movement parameters.

[0059] In one embodiment, reference is made to Figure 4 In step S202, in the initial working mode, if the collected current limb movement parameters of the wearer meet the second preset condition, the step of determining the control command based on the current limb movement parameters includes:

[0060] Step S401: Obtain the initial limb position of the wearer when the user does not make any limb movements in the initial working mode.

[0061] Here, the fitness tracker monitors the user's arm movements when the user's arm is in its initial position. The initial position is obtained in real time based on the actual situation.

[0062] Step S402: Monitor the current limb position of the wearer. If the current limb position is different from the initial limb position, obtain the current limb movement parameters.

[0063] Here, the current limb movement parameters include the current arm movement direction and acceleration state. When the user's arm leaves the initial limb position, the fitness tracker captures all arm movements as control commands.

[0064] Step S403: Determine whether the pause time between the current limb movement parameter and the next limb movement parameter and whether the current limb movement parameter meets the second preset condition; wherein, the second preset condition includes the pause time requirement and the movement parameter requirement.

[0065] Here, the pause time requirement is a preset pause time. An arm movement must pause between two limb movements to determine if the pause time is greater than the preset pause time. If the pause time is less than the preset pause time, the limb movement does not meet the pause time requirement; if the pause time is greater than or equal to the preset pause time, the limb movement meets the pause time requirement.

[0066] Set preset motion parameters and determine if the limb motion parameters are preset. If the limb motion parameters are preset, then the limb motion parameters meet the preset motion parameter requirements; if the limb motion parameters are not preset, then the limb motion parameters do not meet the preset motion parameter requirements.

[0067] The preset motion parameters are any motion that can be recognized by the three-axis motion sensor, including but not limited to horizontal waving, clockwise and counterclockwise circular motions, multi-segment waving, etc.

[0068] Step S404: If the pause time does not meet the pause time requirement or the current limb movement parameters do not meet the movement parameter requirements, enter the empty state until the wearer is detected to have returned to the initial limb position; wherein, the empty state represents the wearable device entering a state of waiting for response and not responding to any limb movement.

[0069] Here, the "empty state" refers to the fitness tracker entering a waiting state, where it does not respond to any action commands. After entering the empty state, the arm needs to return to its initial limb position. Once the fitness tracker detects that the arm has returned to its initial position, it ends the empty state. After ending the empty state, the fitness tracker re-detects arm movements to execute the next command.

[0070] Step S405: If the pause time meets the pause time requirement and the current limb movement parameters meet the movement parameter requirements, the current limb movement parameters are determined as control commands.

[0071] Specifically, for example, a clockwise circular motion can be set to turn on the range hood, and a counter-clockwise circular motion can be set to turn off the range hood; a first wave to the left can be set to activate the range hood's middle setting, such as activating the middle setting for range hoods with settings divided into low, high, and stir-fry modes, or the middle setting for range hoods with settings divided into low, medium, and high modes. After activating the middle setting, a wave to the left can be set to increase the range hood's setting, and a wave to the right can be set to decrease the range hood's setting; a wave to the left followed immediately by an upward wave can be set to turn on the lights, and a wave to the right followed immediately by an upward wave can be set to turn off the lights.

[0072] Step S103: Send the control command to the range hood so that the range hood can perform the corresponding control action according to the control command.

[0073] In one embodiment, after sending the control command to the range hood so that the range hood performs the corresponding control action according to the control command in step S103, the method further includes:

[0074] In the initial working mode, if the collected parameters of the wearer's second limb meet the third preset condition, the initial working mode will be exited.

[0075] Here, the user is set to exit the initial working mode when they lower their arm from the preset or initial limb position to a natural state.

[0076] Reference Figure 5 In the initial working mode, if the collected parameters of the wearer's second limb meet the third preset condition, the steps to exit the initial working mode include:

[0077] Step S501: Obtain the second limb movement parameters and the initial limb position of the second limb movement.

[0078] Here, the parameters of the second limb movement include the second direction of movement and the trend of change of the second acceleration.

[0079] Step S502: If the initial limb position is the same as the preset limb position or the initial limb position, based on the second movement direction of the second limb movement parameter, determine the second angle between the second limb position and the preset limb position when the wearer performs limb movements along the second movement direction within the preset detection time.

[0080] Here, the second direction of movement is upward, and the second angle between the user's arm and the preset limb position or the initial limb position is obtained.

[0081] Step S503: If the second included angle increases from less than the preset second included angle to greater than the preset first included angle within the preset detection time, it is confirmed that the second movement direction meets the preset first closing condition.

[0082] Here, the first preset closing condition is that during the arm movement, the included angle gradually changes from less than 10° to greater than 50° within 1 second.

[0083] Step S504: Obtain the trend of change of the second acceleration. If the trend of change of the second acceleration satisfies the second preset trend, confirm that the trend of change of the second acceleration satisfies the preset second closing condition.

[0084] Here, the second vertical acceleration of the user's lowered arm is obtained within a preset detection time. Based on the motion characteristics of the arm-lowering action, during the process of the user lowering their arm, the second preset trend is that the horizontal acceleration is almost 0, while the vertical acceleration first changes from 0 to a third preset acceleration, then from the third preset acceleration back to 0, then from 0 to a fourth preset acceleration, and finally from the fourth preset acceleration back to 0. The third and fourth preset accelerations can be set according to actual conditions.

[0085] The second preset closing condition is that the second acceleration changes from 0 to the third preset acceleration within 1 second, then changes from the third preset acceleration back to 0, then changes from 0 to the fourth preset acceleration, and finally changes from the fourth preset acceleration back to 0.

[0086] Step S505: When it is confirmed that the second motion direction meets the preset first closing condition and the change trend of the second acceleration meets the preset second closing condition, exit the initial working mode.

[0087] In one embodiment, after sending the control command to the range hood so that the range hood performs the corresponding control action according to the control command in step S103, the method further includes:

[0088] In the idle state, if the current limb movement parameters of the wearer are collected and meet the fourth preset condition, the initial working mode will be exited.

[0089] Here, the user is set to exit control mode when they lower their arm diagonally from an empty position to directly in front of them.

[0090] Reference Figure 6 In the idle state, if the collected current limb movement parameters of the wearer meet the fourth preset condition, the steps to exit the initial working mode include:

[0091] Step S601: Obtain the current limb movement parameters of the wearer.

[0092] Here, we see the changing trends of the third direction of motion and the third acceleration of the current limb movement parameters.

[0093] Step S602: Based on the third direction of movement of the current limb movement parameters, determine the third angle between the third limb position and the preset limb position when the user performs limb movements along the third direction of movement within the preset detection time.

[0094] Here, the third direction of motion is diagonally downward.

[0095] Step S603: If the third included angle increases from less than the preset second included angle to greater than the preset first included angle within the preset detection time, it is confirmed that the third movement direction meets the preset first closing condition.

[0096] Here, the first preset closing condition is that during the arm movement, the included angle gradually changes from less than 10° to greater than 50° within 1 second.

[0097] Step S604: Obtain the trend of change of the third acceleration. If the vertical acceleration trend of the third acceleration satisfies the second preset acceleration trend and the horizontal acceleration trend satisfies the third preset acceleration trend, confirm that the third acceleration trend satisfies the preset third closing condition. The third acceleration trend includes the vertical acceleration trend and the horizontal acceleration trend.

[0098] Here, the vertical and horizontal accelerations of the third acceleration in the vertical direction during the user's arm lowering are obtained within a preset detection time. Based on the motion characteristics of the arm-lowering action, during the user's arm lowering process, the vertical acceleration first changes from 0 to the fifth preset acceleration, then from the fifth preset acceleration back to 0, then from 0 to the sixth preset acceleration, and finally from the sixth preset acceleration back to 0; the horizontal acceleration first changes from 0 to the seventh preset acceleration, then from the seventh preset acceleration back to 0, then from 0 to the eighth preset acceleration, and finally from the eighth preset acceleration back to 0. The preset third closing condition is that during the arm movement, the vertical acceleration changes from 0 to the third preset acceleration within 1 second, then from the third preset acceleration back to 0, then from 0 to the fourth preset acceleration, and finally from the fourth preset acceleration back to 0; the horizontal acceleration first changes from 0 to the seventh preset acceleration, then from the seventh preset acceleration back to 0, then from 0 to the eighth preset acceleration, and finally from the eighth preset acceleration back to 0.

[0099] Step S605: When it is confirmed that the third motion direction meets the preset first closing condition and the third acceleration change trend meets the preset third closing condition, exit the initial working mode.

[0100] In one embodiment, the wearable device further includes a light module and a vibration module; the method further includes:

[0101] When the wearable device enters or exits its initial working mode, the control light module flashes according to preset light rules to remind the user, and the control vibration module vibrates according to preset vibration rules to remind the user.

[0102] In the initial working mode, when the current limb movement parameters meet the preset conditions, the control light module flashes to remind the user according to the preset light rules.

[0103] In the initial working mode, when the current limb movement parameters do not meet the preset conditions, the vibration control module vibrates to remind the user according to the preset vibration rules.

[0104] Specifically, when the wearable device receives a pairing request from the range hood, the light module flashes to indicate that a connection has been established; when the wearable device sends a signal to the range hood to detect whether the communication module is in a connected state, if the connection is lost, the light module flashes to indicate that a new connection has been established.

[0105] When the wearable device enters its initial working mode, the light module flashes and the vibration module vibrates to alert the user; when the wearable device exits its initial working mode, the light flashes and the vibration module vibrates to alert the user.

[0106] When a control command fails to be sent, the vibration module vibrates as a reminder; when a control command is successfully sent, the light module flashes as a reminder.

[0107] The fitness tracker's light module can use different colors to correspond to different states of the range hood, such as yellow for low speed, green for medium speed, and red for high speed.

[0108] This invention provides a control method for a range hood, applied to a wearable device.
