[0038] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of the present invention. For those skilled in the art, the present invention can be applied to other similar scenarios based on these drawings without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0039] As indicated in this invention and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0040] While this invention makes various references to certain modules in an apparatus according to embodiments of the invention, any number of different modules can be used and run on a computing device and / or processor. Modules are merely illustrative, and different aspects of the apparatus and methods may use different modules.

[0041] It should be understood that when a unit or module is described as "connected" or "coupled" to other units, modules, or blocks, it may refer to a direct connection or coupling, or communication with other units, modules, or blocks, or the presence of intermediate units, modules, or blocks, unless the context explicitly indicates otherwise. The term "and / or" as used herein may include any and all combinations of one or more of the related listed items.

[0042] The control system for the range hood provided in this embodiment can be applied to the range hood in this embodiment. The range hood includes a display panel, a fan, a smoke hood, a smoke baffle, and the control system for the range hood.

[0043] like Figure 1 As shown in the figure, this application proposes a control system for a range hood, the system including a mode activation unit 101, a user identification unit 102, a mode matching unit 103, and a mode control unit 104.

[0044] The mode activation unit 101 is used to collect user operation signals.

[0045] The user identification unit 102 is used to collect the current user's physiological information in response to the operation signal.

[0046] For example, the mode activation unit 101 is a power button. When the user type recognition unit 102 is a fingerprint recognition unit, it is located on the power button. Optionally, the user type recognition unit can also be a face recognition unit, located on the range hood.

[0047] The pattern matching unit 103 is used to match the working mode of the range hood based on the physiological information.

[0048] The mode control unit 104 is used to control the operation of the range hood based on the working mode. The working mode includes a care mode, which is obtained by the user customizing the operation strategy of the range hood according to their needs.

[0049] The care mode is a mode designed for user groups who want to reduce the complexity of operation. It is different from the automatic mode known in the prior art. The automatic mode in the prior art is usually fixed at the factory. It cannot be adjusted according to user type or needs during use, nor can it be matched and called based on user type.

[0050] In this embodiment, the mode activation unit collects the user's operation signal; the user identification unit responds to the operation signal and collects the current user's physiological information; the mode matching unit matches the working mode of the range hood based on the physiological information; and the mode control unit controls the operation of the range hood based on the working mode, thereby realizing the adjustment and operation of the range hood working mode for different users, ensuring the intelligence of the range hood while improving the ease of operation for users in the care mode.

[0051] In one embodiment, such as Figure 2 As shown, the system also includes an oil fume sensing unit 105. The oil fume sensing unit 105 is used to collect oil fume information in real time and determine the oil fume level.

[0052] The mode control unit 104 determines the operating level of the fan based on the fume level, and controls the operation of the fan based on the operating level of the fan.

[0053] The oil fume information includes the concentration of oil fumes within the set range of the range hood. The oil fume level of the real-time oil fume information is determined by the level range mapped by the oil fume concentration. For example, oil fume levels are divided into high oil fume, medium oil fume, and low oil fume, where the oil fume concentration corresponding to the high oil fume level is greater than or equal to a%, the oil fume concentration corresponding to the medium oil fume level is greater than or equal to b% and less than or equal to a%, and the oil fume concentration corresponding to the low oil fume level is less than or equal to b%. In the above example, a is greater than b.

[0054] In one embodiment, when the fume sensing unit 105 determines, based on the fume information, that the duration without fumes has reached a first preset duration, the mode control unit 104 controls the fan to turn off; when the fume sensing unit 105 determines, based on the fume information, that the duration without fumes has reached a second preset duration after the fan has turned off, the mode control unit 104 controls the range hood to turn off.

[0055] Specifically, if the concentration of oil fumes around the range hood is close to zero according to the oil fume information, then it can be determined that there is no oil fume at that moment. When the oil fume sensing unit 105 determines that the duration of no oil fume has reached a first preset duration, it means that oil fume removal is not required at this time, and the mode control unit 104 controls the fan to turn off. After the fan turns off, the oil fume sensing unit 105 continues to monitor the oil fume information in the environment. When the duration of the oil fume-free state reaches a second preset duration, the mode control unit 104 controls the range hood to turn off.

[0056] In this embodiment, the fume sensing unit collects fume information from the surrounding environment of the range hood, and the mode control module controls the fan based on this information to achieve intelligent fume removal. Furthermore, when the fume sensing unit detects no fume for a second preset duration, the mode control unit 104 shuts down the range hood, automatically stopping both the fan and the range hood. This prevents the range hood from continuously operating in an unsupervised environment, thus avoiding energy waste and other electrical hazards.

[0057] In one embodiment, such as Figure 3 As shown, the system also includes a gas leak detection unit 106 and a first alarm notification unit 107. The gas leak detection unit 106 is used to collect gas concentration information near the gas pipeline and issue a gas leak signal when the concentration reaches a preset level.

[0058] The first alarm notification unit 107 is used to output a first alarm signal based on the gas leak signal.

[0059] Based on the gas leak signal, the mode control unit 104 controls the fan to operate at the highest operating level and also controls the gas pipeline to close.

[0060] Specifically, to prevent fires caused by gas leaks during range hood operation, this embodiment includes a gas leak detection unit 106 that collects gas concentration information near the gas pipeline and issues a gas leak signal when the concentration reaches a preset level. The first alarm notification unit 107 then issues an alarm. Based on the gas leak signal, the mode control unit 104 controls the fan to operate at its highest operating level, absorbing and expelling most of the gas. Simultaneously, it controls the gas pipeline to close, ensuring gas safety during range hood use.

[0061] In one embodiment, such as Figure 4 As shown, the system also includes a dry-burning detection unit 108 and a second alarm notification unit 109. The dry-burning detection unit 108 is used to collect the temperature information of the cookware and issue a dry-burning signal when the preset temperature is reached. The dry-burning detection unit 108 is a non-contact sensor, such as an infrared sensor or a temperature sensor, and is installed on the range hood.

[0062] The second alarm notification unit 109 is used to output a second alarm signal based on the dry burning signal.

[0063] Based on the dry-burning signal, the mode control unit 104 controls the fan to operate at the highest operating level and also controls the gas pipeline to shut down.

[0064] Specifically, the dry-burning detection unit 108 collects the temperature information of the cookware and issues a dry-burning signal when the cookware reaches a preset temperature, prompting an alarm from the second alarm notification unit 109. Upon receiving the dry-burning signal, the mode control unit 104 controls the fan to operate at its highest operating level to quickly handle the large amount of oil fumes generated by the dry-burning of the cookware. Simultaneously, it controls the gas pipeline to shut off to prevent continuous dry-burning from causing a fire. The system achieves automatic dry-burning control without the need for complex human-machine interaction.

[0065] In the two embodiments described above, alarm reminders are issued via the first alarm notification unit 107 and the second alarm notification unit 109, respectively. The alarm reminders can be voice alerts, and are repeated in a loop with increasing volume at intervals. Preferably, if a gas leak or dry-burning of a cookware occurs and the linkage control of the gas pipeline fails, and the system's gas leak identification unit 106 or dry-burning identification unit 108 continuously monitors the situation for a set time without resolving it, the system automatically sends a hazard notification to pre-stored emergency contact persons.

[0066] In one embodiment, such as Figure 5 As shown, the system also includes an interaction unit 110. The interaction unit 110 is used to interact with the user, and when the matched working mode is the care mode, it hides the icon used to input manual control commands.

[0067] Specifically, in Care Mode, icons for inputting manual control commands are hidden, reducing complex human-computer interaction processes and improving the ease of operation for users of Care Mode.

[0068] In one embodiment, such as Figure 6 As shown, the system also includes a mode setting unit 111. The mode setting unit 111 is used to set the matching relationship between the physiological information and the working mode, and to customize the operating strategy of the range hood corresponding to the working mode.

[0069] Specifically, users can set corresponding operating modes for the recorded physiological information, such as fingerprints, faces, and pupils, through the mode setting unit 111. In addition to the predefined standard mode and care mode, users can also adjust the care mode or generate other operating modes by customizing the range hood's operating strategy, realizing the adjustability of the range hood's intelligent functions.

[0070] For example, before the range hood is first used or when the user type needs to be changed, taking fingerprint collection as an example, the user can be customized and named using a mode setting unit, supporting any method such as name or code. After the fingerprint sensor collects the user's fingerprint information, the fingerprint information is stored. Based on the user's low interaction needs, the user's fingerprint information is set to the care mode, and the operating strategy of the range hood in care mode is set, such as adaptive adjustment of fan speed, adaptive adjustment of smoke baffle, and automatic lifting of the range hood. The music that the user wants to listen to during cooking can also be set, such as excerpts from dramas or crosstalk that are popular with the elderly.

[0071] In one embodiment, only the power button remains constantly lit in the care mode. Preferably, in addition to the power button, the range hood's display panel can also include easily understood function buttons such as fan speed adjustment and lighting, which are always illuminated. In care mode, if the user manually presses the fan speed adjustment button, the adaptive fan operation level adjustment based on the fume level performed by the mode control unit 104 will be deactivated, and the fan operation level will be adjusted according to manual operation.

[0072] In one embodiment, the range hood also includes a communication module that supports wireless networking and can connect to a mobile device. The mobile application software allows for user information input, customization of the fan's operating mode, remote control, and alarm notifications.

[0073] The various units in the control system of the aforementioned range hood can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor of a computer device in hardware form or independent of it, or stored in the memory of a computer device in software form, so that the processor can call and execute the corresponding operations of each module.

The system includes a mode activation unit 101, a user identification unit 102, a mode matching unit 103, a mode control unit 104, a fume sensing unit 105, a gas leak detection unit 106, a first alarm notification unit 107, a dry burning detection unit 108, a second alarm notification unit 109, an interaction unit 110, and a mode setting unit 111.
