[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] The following describes a control method for a range hood and a range hood according to embodiments of the present invention with reference to the accompanying drawings.

[0039] like Figures 1 to 5 As shown, the control method of the range hood according to the embodiment of the present invention includes the following steps:

[0040] S1: Detecting the temperatures of multiple temperature points within the working area through the control component 2;

[0041] S2: Multiple temperature points act in the working area through biological heat sources to produce temperature changes;

[0042] S3: Convert the temperature change into an indication signal through the control component 2;

[0043] S4: Control the operation of the range hood body 1 through the indication signal.

[0044] According to the range hood control method of the embodiment of the present invention, when the bioheat source operates within the working area, the temperature of multiple temperature points within the working area can change. Therefore, when the user's hands, feet, or other limbs operate within the working area, the temperature difference between the human body and the temperature within the working area causes the temperature of the temperature points to change. The control component 2 of the range hood of the embodiment of the present invention can convert the temperature change of the temperature point into an indicator signal, and then control the operation of the range hood body 1 through the indicator signal. Therefore, the range hood control method of the embodiment of the present invention can eliminate the need for the user to touch the outer surface of the range hood when operating the range hood, making the range hood control more convenient, improving the cleanliness of the range hood surface, and reducing the subsequent maintenance time of the range hood.

[0045] In addition, the range hood of the embodiment of the present invention controls the operation of the range hood by detecting the temperature change between the human body and the temperature point, so that the control component 2 can be normally started only when the user performs the set action, thereby improving the range hood's ability to prevent accidental touch to a certain extent, and further improving the reliability of the range hood during operation.

[0046] In some embodiments, the bio-heat source is a human hand, and the indication signal is a hand gesture. It is understood that when the user's hand moves within the working area, the control component 2 can convert the temperature change at the temperature point into a hand gesture signal, thereby controlling the operation of the range hood body 1. Furthermore, when the user uses the range hood, they can control the operation of the range hood through simple hand movements, thereby improving the convenience of using the range hood.

[0047] Specifically, the control assembly 2 includes a pyroelectric module 21 and a main control module 22. The pyroelectric module 21 is connected to the main control module 22. The pyroelectric module 21 detects temperature changes at multiple temperature points, while the main control module 22 converts these temperature changes into gesture signals. When a hand moves within the work area, the main control module 22 converts the temperature changes at multiple temperature points into hand shapes, thereby sensing the hand movements and converting them into gesture signals.

[0048] It is understood that the main control module uses an algorithm to convert the temperature changes at multiple temperature points into hand shapes, then determines the hand gesture based on the time difference between the forward and backward movements of the hand, and converts it into gesture signals to control the operation of the range hood. Controlling the operation of the range hood includes: controlling the opening and closing of the range hood body 1, controlling the exhaust volume of the range hood, controlling the lighting of the range hood, etc.

[0049] Optionally, the pyroelectric module 21 detects 256 temperature points. It will be appreciated that these 256 temperature points are evenly distributed within the working area, further improving the accuracy of the pyroelectric module's detection. When a hand is inserted into the working area, the temperature difference between the hand and the working area causes the temperature of each temperature point to change. Therefore, the main control module 22 can calculate parameters such as the direction of hand movement, hand movement posture, or hand movement time based on the temperature changes at the temperature points detected by the pyroelectric module 21, and convert these parameters into gesture signals.

[0050] Preferably, the main control module 22 converts hand movements into gesture signals only when the temperature of one or more temperature points of the pyroelectric module 21 and the temperatures of surrounding temperature points exceed a preset value. It is understood that when non-hand objects move within the working area, the pyroelectric module 21 will not trigger the main control module 22, thereby avoiding the risk of accidental touches on the range hood body 1 and improving the reliability of the range hood during operation.

[0051] In some embodiments, as Figure 1 and Figure 2 As shown, the range hood body 1 is provided with a smoke exhaust port 111, and the main control module 22 is configured to adjust the smoke exhaust volume of the smoke exhaust port 111 based on gesture signals. It is understood that the user can adjust the smoke exhaust speed of the smoke exhaust port 111 by performing hand movements within the working area, thereby selecting different gears corresponding to the range hood according to the usage status of the range hood stove 3 or different cooking methods.

[0052] For example, you can set the range hood's gears to Standby, On, Lighting, Stir-fry on / off, and Stir-fry off as you move your hand from left to right within the work area. Stir-fry, High, Low, Delayed Shutdown, and Off as you move your hand from right to left. When your hand hovers, the range hood's gears will be Off, Standby, On, Lighting, Low, and High.

[0053] It can be understood that hand movements include translation, hovering and flipping of the hand. Hand movements also include the direction of hand translation, the number of hand translations, the time of hand translation, the time of hand hovering, the direction of hand flipping, the time of hand flipping, and the number of hand flipping. In other words, different hand movements correspond to different functions and gears of the range hood. Therefore, the range hood of the embodiment of the present invention can be set with corresponding hand movements according to different functions and gears, thereby improving the practicality of the range hood.

[0054] The range hood according to an embodiment of the present invention includes a range hood body 1, a pyroelectric module 21, and a main control module 22. The pyroelectric module 21 and the main control module 22 are mounted on the range hood body 1 and connected to each other. The pyroelectric module 21 is configured to detect temperature changes at multiple temperature points, while the main control module 22 is configured to convert these temperature changes into gesture signals. When a hand moves within the working area, the main control module 22 can convert the temperature changes at multiple temperature points into hand shapes, thereby sensing the hand movements and converting them into gesture signals to control the operation of the range hood body.

[0055] It is understandable that if Figure 1 and Figure 2 As shown, the working area is the area sensed by the pyroelectric module 21 . For example, the working area may be located below the range hood body 1 , in front of the range hood body 1 , or on the side of the range hood body 1 .

[0056] In some embodiments, as Figure 1 As shown, there are multiple smoke exhaust ports 111 and multiple working areas, each of which corresponds to a plurality of smoke exhaust ports 111. When hand movements change between different working areas, the main control module 22 can control the smoke exhaust volume of the smoke exhaust ports 111 corresponding to the different working areas. It is understandable that the multiple smoke exhaust ports 111 correspond to multiple range hoods 3, and the user can perform hand movements in different working areas to control the smoke exhaust volume of different smoke exhaust ports 111 corresponding to different range hoods 3, thereby improving the compatibility of the range hood of the embodiment of the present invention.

[0057] Specifically, if Figure 1 and Figure 4 As shown, the range hood body 1 includes a housing 11 and a fan 12. The fan 12 is disposed within the housing 11. A plurality of smoke exhaust ports 111 are disposed on the housing 11. Each of the plurality of smoke exhaust ports 111 corresponds to the fan 12. The main control module 22 is connected to the fan 12 to control the amount of smoke exhausted from the plurality of smoke exhaust ports 111. It will be understood that the smoke exhaust ports 111 are disposed at the lower end of the housing 11, the air inlet of the fan 12 is opposite to the smoke exhaust ports 111, and the air outlet of the fan 12 is in communication with the exterior of the housing 11. The range hood according to the embodiment of the present invention controls the amount of smoke exhausted from the smoke exhaust ports 111 by the rotation of the fan 12.

[0058] In some embodiments, as Figure 1 As shown, there are two smoke exhaust ports 111, which are located below the range hood body 1 and spaced apart on the left and right sides. There are two working areas, one on the left and one on the right side of the range hood body 1, corresponding to the two smoke exhaust ports 111. The user can control the smoke exhaust volume of the two smoke exhaust ports 111 by moving their hands within the two working areas.

[0059] Specifically, if Figure 1 and Figure 4 As shown, the range hood further includes a flap 13 and a motor 14. The flap 13 is connected to the motor 14 and the housing 11. The motor 14 can drive the flap 13 to rotate so that the flap 13 opens or closes the smoke exhaust port 111. It is understood that when the range hood is in use, the motor 14 drives the flap 13 to open the smoke exhaust port 111; when the range hood is not in use, the motor 14 drives the flap 13 to close the smoke exhaust port 111. Furthermore, the motor 14 is connected to the main control module 22, so that the user can control the rotation of the motor 14 through gestures, allowing the user to open the closable flap 13 in a contactless manner, thereby further improving the convenience of using the range hood.

[0060] Optionally, there is one fan 12, and the air inlet of one fan 12 is opposite to multiple smoke exhaust ports 111. It can be understood that the range hood of the embodiment of the present invention controls the smoke exhaust volume of multiple smoke exhaust ports 111 through one fan 12, thereby reducing the production cost of the range hood and facilitating the later installation and disassembly of the range hood.

[0061] Optionally, there are multiple fans 12, and the multiple smoke exhaust ports 111 correspond one-to-one to the multiple fans 12. It is understandable that the range hood of the embodiment of the present invention controls the smoke exhaust volume of different smoke exhaust ports 111 through different fans 12, thereby improving the smoke exhaust efficiency of the range hood, and when one of the fans 12 fails, the remaining fans 12 can serve as backup, thereby improving the reliability of the range hood during operation.

[0062] In some embodiments, as Figure 1 and Figure 2 As shown, the range hood body 1 is arranged above the range hood stove 3, and the working area is located between the range hood body 1 and the range hood stove 3. Therefore, when the user uses the range hood, he can directly raise his hand upward to send a gesture signal to control the operation of the range hood, thereby improving the convenience of using the range hood of the embodiment of the present invention.
