[0044] To make the objectives, technical solutions, and advantages of the present invention more clear, the following will refer to the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the present invention through implementation methods. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the basic concepts disclosed and suggested by the embodiments of the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.

[0045] When the key module and gesture module of the range hood are close to each other, the user's hand may easily block the gesture module when operating the key, causing the range hood to detect the gesture action signal and mistakenly trigger the gesture function. In order to avoid the gesture function being mistakenly triggered when operating the key, an embodiment of the present invention provides a control method for the range hood. Figure 1 Flowchart of a control method of a range hood provided by an embodiment of the present invention. Figure 1 As shown, the control method includes:

[0046] S110 , detecting key signals and gesture action signals in real time.

[0047] S120: When a key signal is detected, execute the key function corresponding to the key signal, and keep the gesture function in a closed state under a first preset condition.

[0048] Figure 2 This is a schematic structural diagram of a range hood provided by an embodiment of the present invention. For example, referring to Figure 2Specifically, after the range hood is powered on, the control module 10 detects key signals and gesture action signals in real time. Since gesture action signals such as single-clicking, waving left, waving right, etc. require the hand to leave the sensing area of ​​the infrared gesture module 30 before the gesture action signal is considered valid, the hovering gesture action requires the hand to be placed in the sensing area for a period of time, while the key signal is immediately effective when pressed, so when the user's action is to operate a key, the control module 10 will first detect the key signal. When the control module 10 detects the key signal, it controls the range hood to execute the key function corresponding to the key signal. At the same time, the control module 10 feeds back the adjustment instruction so that the range hood keeps the gesture function in the off state under the first preset condition, such as within the preset time. That is, under the first preset condition, even if the key action is mistakenly identified as a gesture action and the gesture action signal is detected, the gesture function corresponding to the gesture action signal will not be executed. Therefore, under the first preset condition, even if the button module 20 and the infrared gesture module 30 are close to each other, whether the user operates the button normally or uses gestures to control the range hood, the button function and the gesture function will not affect each other, ensuring that the gesture function is not triggered by mistake when operating the button, thereby improving the reliability and intelligence of the range hood and enhancing the user experience.

[0049] The range hood control method provided by the embodiments of the present invention maintains the gesture function in a disabled state under a first preset condition when a key signal is detected. This ensures that, even if a gesture action signal is detected under the first preset condition, the gesture function corresponding to the gesture action signal will not be executed. Therefore, if the key module and the infrared gesture module are close together, the key function and the gesture function do not interfere with each other, ensuring that the gesture function is not accidentally triggered when the key is pressed. This improves the reliability and intelligence of the range hood and enhances the user experience.

[0050] Optionally, Figure 3 FIG. 1 is a flow chart of another range hood control method provided by an embodiment of the present invention. Figure 3 As shown, the control method includes:

[0051] S210: Detect key signals and gesture action signals in real time.

[0052] S220: When a key signal is detected, execute the key function corresponding to the key signal, and when the duration between the detection of the gesture action signal and the detection of the key signal is less than or equal to the preset duration, keep the gesture function in the off state.

[0053] In this embodiment, the first preset condition is that the time between the detection of the gesture action signal and the detection of the key signal is less than or equal to the preset time. Figure 2When the control module 10 detects a key signal, it feeds back an adjustment instruction to keep the gesture function in the off state for a preset time, such as 3 seconds, after the key signal is detected. That is, when the time between the detection of the gesture action signal and the detection of the key signal is less than or equal to the preset time, the gesture function is locked, so that within the preset time, even if the key action is mistakenly identified as a gesture action and the gesture action signal is detected, the gesture function corresponding to the gesture action signal will not be executed. In this way, when the key module 20 and the infrared gesture module 30 are close to each other, the key function and the gesture function do not interfere with each other, ensuring that the gesture function is not mistakenly triggered when the key is operated, thereby improving the reliability and intelligence of the range hood and enhancing the user experience. Among them, the specific value of the preset time is not limited, and those skilled in the art can set it according to actual needs.

[0054] Optionally, Figure 4 FIG. 1 is a flow chart of another range hood control method provided by an embodiment of the present invention. Figure 4 As shown, the control method includes:

[0055] S310: Detect key signals and gesture action signals in real time.

[0056] S320: When a key signal is detected, execute the key function corresponding to the key signal, and when the number of gesture action signals detected after the key signal is detected is less than or equal to a preset number, keep the gesture function in a closed state.

[0057] In this embodiment, the first preset condition is that the number of gesture action signals detected after the key signal is detected is less than or equal to the preset number. Figure 2 When the control module 10 detects a key signal, it feeds back an adjustment instruction so that after detecting the key signal, when the number of times the gesture action signal is detected is within the preset number, the gesture function is kept in the off state. Taking the preset number of times as 2 as an example, after the control module 10 detects the key signal, the range hood will not execute the gesture function corresponding to the gesture action signal when the gesture control signal is detected for the first and second time. In this way, when the key module 20 and the infrared gesture module 30 are close to each other, it can be achieved that the gesture function is not mistakenly triggered when the key is operated, which can improve the reliability and intelligence of the range hood and enhance the user experience. Among them, the specific value of the preset number is not limited, and those skilled in the art can set it according to actual needs.

[0058] The following lists specific implementations to explain how to keep the gesture function turned off under the first preset condition.

[0059] refer to Figure 1 and Figure 2Optionally, S120, keeping the gesture function closed under the first preset condition, includes: under the first preset condition, not executing the gesture function corresponding to the gesture action signal.

[0060] The control module 10 itself controls the range hood to execute the gesture function corresponding to the received gesture action signal. Under a first preset condition, even if the control module 10 receives or detects a gesture action signal, it does not execute the corresponding gesture function, thereby disabling the gesture function. In this embodiment, the control module 10 is configured to only disable the gesture function corresponding to the gesture action signal under the first preset condition. This does not alter the control module 10's ability to execute various functions in other situations, nor does it change the functional settings of other modules in the range hood. This method is simple, efficient, and highly operational.

[0061] refer to Figure 1 and Figure 2 Optionally, the range hood includes an infrared gesture module 30; S120, keeping the gesture function off under the first preset condition, including: under the first preset condition, turning off the function of the infrared gesture module to generate a gesture action signal according to the infrared signal; or, under the first preset condition, turning off the function of transmitting the gesture action signal with the infrared gesture module.

[0062] The infrared gesture module 30 itself has the function of generating gesture action signals based on infrared signals and outputting the gesture action signals to the control module 10. Under a first preset condition, the control module 10 can control the infrared gesture module 30 to not execute or temporarily disable the function of generating gesture action signals based on infrared signals when an infrared signal is detected, thereby achieving the gesture function being in a disabled state.

[0063] In addition, under the first preset condition, even if the infrared gesture module 30 generates a gesture action signal based on the infrared signal, the control module 10 can control the infrared gesture module 30 not to execute or temporarily turn off the function of outputting the gesture action signal to the control module 10; or the control module 10 can not execute or temporarily turn off the function of receiving the gesture action signal output by the infrared gesture module 30, that is, under the first preset condition, the function of transmitting the gesture action signal between the control module 10 and the infrared gesture module 30 can be turned off, so that the gesture function is in the off state.

[0064] refer to Figure 1 and Figure 2 Optionally, the range hood includes an infrared gesture module 30, and the infrared gesture module 30 includes an infrared emitting unit 31 and an infrared receiving unit 32; S120, keeping the gesture function off under the first preset condition, includes: under the first preset condition, turning off the function of the infrared emitting unit to emit infrared rays; and / or, under the first preset condition, turning off the function of the infrared receiving unit to receive infrared rays.

[0065] The infrared gesture module 30 performs gesture recognition as follows: the infrared emitting unit 31 emits infrared light, the infrared receiving unit 32 receives the infrared light that has been altered by the gesture and generates an infrared signal. The infrared receiving unit 32 then generates a gesture action signal based on the infrared signal, thereby recognizing the gesture. To keep the gesture function disabled under the first preset condition, the control module 10 can control the infrared emitting unit 31 to not transmit or temporarily disable the infrared emitting function, and can also control the infrared receiving unit 32 to not transmit or temporarily disable the infrared receiving function under the first preset condition. This does not affect the corresponding functions of the control module 10 and other modules.

[0066] Optionally, Figure 5 FIG. 1 is a flow chart of another range hood control method provided by an embodiment of the present invention. Figure 5 As shown, the control method includes:

[0067] S410: Detect key signals and gesture action signals in real time.

[0068] S420: When a key signal is detected, execute the key function corresponding to the key signal, and keep the gesture function in a closed state under a first preset condition.

[0069] S430: Under the second preset condition, keep the button function and gesture function enabled.

[0070] refer to Figure 2 When the control module 10 detects a key signal, it feeds back an adjustment instruction to keep the range hood's gesture function in the off state under a first preset condition. This ensures that, even if a gesture action signal is mistakenly recognized under the first preset condition, the gesture function corresponding to the gesture action signal will not be executed. Subsequently, the control module 10 feeds back an adjustment instruction to keep both the key and gesture functions in the on state under a second preset condition, thereby restoring the gesture function and allowing subsequent users to control the range hood through gestures. The range hood or the control module 10 can then re-enter a loop of detecting key signals and gesture action signals to ensure that the gesture function is not mistakenly triggered each time the user presses a key, further improving the user experience.

[0071] Optionally, Figure 6 FIG. 1 is a flow chart of another range hood control method provided by an embodiment of the present invention. Figure 6 As shown, the control method includes:

[0072] S510: Detect key signals and gesture action signals in real time.

[0073] S520: When a key signal is detected, execute the key function corresponding to the key signal, and keep the gesture function in a closed state under a first preset condition.

[0074] S530: When the duration between the detection of a gesture action signal and the detection of a key signal is greater than a preset duration, keep the key function and the gesture function turned on; or, when the number of gesture action signals detected after the detection of a key signal is greater than a preset number, keep the key function and the gesture function turned on.

[0075] In this embodiment, the second preset condition can be that the time between the detection of the gesture action signal and the detection of the key signal is greater than the preset time. Figure 2 When the control module 10 detects a key signal, under a first preset condition, such as a preset time period after detecting the key signal, the gesture function remains disabled, i.e., the gesture function is locked. During this time, even if a gesture action signal is mistakenly recognized, no immediate response is given. The control module 10 detects that the gesture action signal has been received for a predetermined time period, i.e., the gesture function lock period. At this point, the control module 10 feeds back an adjustment signal to enable both the key function and the gesture function, unlocking the gesture function. The range hood can then execute the gesture function based on the received gesture action signal. Subsequently, the key signal and gesture control signal can be re-detected and the aforementioned control process repeated.

[0076] In this embodiment, the second preset condition may also be that the number of gesture action signals detected after the key signal is detected is greater than the preset number. Figure 2 When the control module 10 detects a key signal, under a first preset condition, such as if the number of gesture action signals detected after the key signal is detected falls within a preset number, the gesture function remains disabled, i.e., the gesture function is locked. At this point, even if a gesture action signal is mistakenly recognized, no immediate response is given until the control module 10 detects that the gesture function lock count, i.e., the preset number of times, has been exceeded. At this point, the control module 10 feeds back an adjustment signal to enable both the key and gesture functions, unlocking the gesture function. The range hood can then execute the gesture function based on the received gesture action signal. Subsequently, the key and gesture action signals can be re-detected and the aforementioned control process repeated.

[0077] It should be noted that, referring to the above description, the second preset condition and the first preset condition can correspond one to one, that is, the specific value of the preset duration in the first preset condition is the same as the specific value of the preset duration in the second preset condition, or the specific value of the preset number of times in the first preset condition is the same as the specific value of the preset number of times in the second preset condition. In this way, the first preset condition and the second preset condition can be seamlessly connected, and the entire control logic is concise and efficient.

[0078] To facilitate understanding of the control method of the range hood provided by the embodiment of the present invention, based on the above description, a specific control method is now provided. For example, Figure 7 This is a flow chart of another range hood control method provided by an embodiment of the present invention. Figure 7 For relevant content, please refer to the above text and will not be repeated here.

[0079] Based on the same inventive concept, an embodiment of the present invention further provides a range hood, which can execute the range hood control method provided by any embodiment of the present invention. Figure 2 The range hood provided by the embodiment of the present invention includes: a control module 10, a button module 20 and an infrared gesture module 30; the button module 20 is electrically connected to the control module 10, and is used to receive button information input by the user, generate a button signal according to the button information, and output the button signal to the control module 10; the infrared gesture module 30 is electrically connected to the control module 10, and is used to generate a gesture action signal according to the infrared signal, and output the gesture action signal to the control module 10; the control module 10 is used to detect the button signal and the gesture action signal in real time, execute the button function corresponding to the button signal when the button signal is detected, and keep the gesture function closed under the first preset condition.

[0080] In the range hood provided by the embodiment of the present invention, the control module, upon detecting a key signal, disables the gesture function under a first preset condition. This means that even if a gesture action signal is detected under the first preset condition, the gesture function corresponding to the gesture action signal will not be executed. Therefore, if the key module and the infrared gesture module are close together, the key function and the gesture function do not interfere with each other, ensuring that the gesture function is not accidentally triggered when the key is pressed. This improves the reliability and intelligence of the range hood and enhances the user experience.

[0081] Figure 8 FIG. 1 is a schematic diagram of the layout structure of a control panel of a range hood provided by an embodiment of the present invention, such as Figure 8 As shown, optionally, the range hood further includes a control panel 40 , and the button module 20 and the infrared gesture module 30 are arranged in adjacent areas on the control panel 40 .

[0082] The infrared gesture module 30 and the key module 20 can be centrally located to make the range hood more compact. Preferably, the key module 20 has an area of ​​less than 8cm*4cm. The infrared gesture module 30 is positioned closely to the key module 20 to ensure it can sense your hand when a key is pressed. The infrared gesture module 30 can be located below, to the right of, or anywhere else near the key module 20.
