Description

[0002] As living standards improve, more and more electronic devices are becoming part of our daily lives. Range hoods are now an essential appliance in every household. Installed above the kitchen gas stove, they absorb cooking fumes and exhaust them outdoors, reducing air pollution in the kitchen. Cooking produces a variety of harmful gases, which can be very harmful to the human body. When the range hood is connected to an AC power source, the left and right motors drive the left and right fans to rotate at high speed, creating a negative pressure zone at the center of the fans. Once the fumes enter this negative pressure zone, centrifugal force accelerates the combustion waste from the stove and harmful cooking fumes out of the fan gaps. These fumes are then discharged through a common exhaust vent, reducing pollution, purifying the air, and providing safety features such as anti-toxic and explosion protection. However, currently used range hoods can only detect a single harmful substance, resulting in large errors in image and temperature acquisition calculations, high energy consumption, and a poor user experience.

[0039] Those skilled in the art will appreciate that although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0040] Please refer to the attached Figure 1 To the attached Figure 3 The oil smoke detection device and detection method of the present invention are described.

[0041] Range hoods are an essential appliance in today's homes. Installed above the kitchen gas stove, they absorb cooking fumes and expel them outdoors, reducing air pollution in the kitchen. However, cooking produces a variety of harmful gases, which can pose serious health risks, such as cancer. Fumes include polycyclic aromatic hydrocarbons (PAHs), a significant portion of which are carcinogenic, such as benzo[α]pyrene. However, current range hoods can only detect a single harmful substance, resulting in large errors in image and temperature acquisition calculations, high energy consumption, and a poor user experience.

[0042] Therefore, an oil fume detection device and detection method are designed to solve the above-mentioned problems that the current range hoods can only identify a single harmful substance, have large image / temperature acquisition calculation errors, high energy consumption, and poor user experience.

[0043] like Figure 1 As shown, an oil fume detection device in the present invention includes a shell 1, on which a control module 2, a sensor matrix 3, an air outlet component 4 and a panel 11 are provided. The control module 2 is arranged on the upper part of the panel 11, and the control module 2 is electrically connected to the sensor matrix 3. In a kitchen environment, the content and types of harmful substances in the kitchen are changing. The sensor matrix 3 can be used to detect different types of oil fumes to feed back the detection information to the control module 2. The control module 2 controls the air outlet component 4 to discharge air to clean different oil fumes to different degrees.

[0044] The sensor matrix 3 detects different types of harmful substances in the oil smoke and feeds the detection information back to the control module 2. The control module 2 controls the air outlet component 4 to discharge air to clean different types of oil smoke, thereby achieving energy saving and improving the user experience.

[0045] Further, if Figure 1 and Figure 2 As shown, the sensor matrix 3 includes a circuit board 31 and a plurality of sensors 32. The plurality of sensors 32 are plugged into the circuit board 31, and each sensor 32 detects a harmful substance in the oil smoke. Specifically, the plurality of sensors 32 are arranged in a matrix along a first direction and a second direction on the circuit board 31. The circuit board 31 is also provided with a plurality of reserved ports 311 for repairing or replacing the sensors 32, so as to facilitate replacement of the sensors 32 on the circuit board 31, so that the user can replace the required sensor 32 on the circuit board 31. In this embodiment, the first direction is Figure 2 The direction shown by L1 in the figure, the second direction is Figure 2 The direction shown by L2.

[0046] Due to differences in cooking methods and dietary habits across regions, the pollutants present in kitchen fumes also vary. The design of sensor matrix 3 facilitates the combination of different sensors 32 based on region. The reserved ports 311 within sensor matrix 3 allow for the addition or replacement of new sensors 32 to identify new harmful substances in cooking fumes, even if no corresponding sensors 32 are available within sensor matrix 3. In this embodiment, sensor matrix 3 includes, but is not limited to, sensors 32 for identifying harmful substances such as alkanes, alkenes, halogenated hydrocarbons, aldehydes, ketones, alcohols, esters, benzene series, and heterocyclic compounds.

[0047] Further, if Figure 1 and Figure 2 As shown, when harmful substances are present in the fume, the corresponding sensor 32 is turned on for detection. If no harmful substances are present in the fume, the corresponding sensor 32 is turned off. Different sensors 32 in the sensor matrix 3 can identify different types of harmful substances. The on / off state of each sensor 32 can be adjusted, so that only the sensors 32 corresponding to the harmful substances present in the fume are turned on, and the sensors 32 corresponding to the harmful substances not present are turned off, thereby achieving the effect of energy saving and extending the service life of the sensors 32.

[0048] Specifically, when detecting harmful substances in cooking fumes, the sensor matrix 3 detects the harmful substances in the cooking fumes. When one or more of the multiple sensors 32 detect their corresponding harmful substances, the sensor 32 remains in an on state. Since the other sensors 32 do not detect their corresponding harmful substances, they can be turned off, thereby achieving the effect of saving energy while extending the service life of the sensors 32. For the sensors 32 that detect harmful substances, the sensors 32 feed back the detected information to the control module 2. The control module 2 determines whether the concentration of the harmful substances detected by the sensors 32 is greater than or equal to a first preset value. If the concentration of the harmful substances is determined to be greater than or equal to the first preset value, the control module 2 controls the air outlet component 4 to discharge air to remove the harmful substances in the air. The air outlet component 4 can blow the harmful substances to a designated area, or it can be combined with the exhaust component to exhaust the harmful substances outdoors.

[0049] By maintaining control module 2 in operation for a period of time, and when the operating time is less than a first preset time, the air output volume of air outlet assembly 4 is maintained unchanged, thereby helping to save energy. Furthermore, this avoids the problem of increased wear and tear and shortened lifespan of air outlet assembly 4 caused by frequent activation of air outlet assembly 4. If the oil smoke sensor 32 detects a high and prolonged concentration of oil smoke, the speed of air outlet assembly 4 is increased to obtain a higher air volume and remove harmful substances from the air.

[0050] Optionally, after the concentration of the harmful substance detected by the sensor 32 is set as a first concentration value, after obtaining the first concentration value, it is determined whether the first concentration value is greater than or equal to a first preset value, and one of the following two situations will be obtained:

[0051] Case 1: The first concentration value is less than the first preset value. In this case, the concentration of the harmful substance is relatively low, and the rotation speed of the air outlet component 4 of the range hood is kept unchanged.

[0052] Case 2: The first concentration value is greater than or equal to the first preset value. In this case, the durations during which the first concentration value is greater than or equal to the first preset value are recorded to obtain a first duration corresponding to the first concentration value. It is then determined whether the first duration is greater than or equal to the first preset duration. If it is determined that the first duration is greater than or equal to the first preset duration, the air output of the air outlet component 4 is increased.

[0053] If the concentration of the harmful substance is greater than or equal to a first preset value and lasts for a period of time greater than or equal to the first preset time, the exhaust component of the range hood is turned on and maintained for a certain period of time simultaneously with or after increasing the air volume of the air outlet component 4. Turning on the exhaust component of the range hood can quickly exhaust the harmful substances blown by the air outlet component 4 to the outside, thereby ensuring good indoor air quality.

[0054] If, after increasing the air volume of the air outlet assembly 4, a high concentration of harmful substances is still detected, the concentration of harmful substances is greater than or equal to the first preset value, and the high concentration of harmful substances persists for a long period of time, the duration of which is greater than or equal to the first preset time, then the air outlet assembly 4 continues to operate at the increased air volume to reduce the concentration of harmful substances as quickly as possible. If, after increasing the air volume of the air outlet assembly 4 for a period of time, the concentration of harmful substances is detected to have decreased, and the concentration of harmful substances is less than the first preset value, indicating that the concentration of harmful substances in the room is low, then the air volume of the range hood's air outlet assembly 4 is reduced to save energy.

[0055] Specifically, when a user uses the range hood, the air volume of the air outlet component 4 is set to a certain level. At this time, the air volume is at a first air volume. If it is determined that the concentration of harmful substances is greater than or equal to a first preset value and lasts for a period greater than or equal to the first preset time, the air volume of the air outlet component 4 is increased from the first air volume to a second air volume. Since the second air volume is larger, the range hood has a stronger ability to absorb oil fumes when the air volume is at the second air volume. After the second preset time, the concentration of harmful substances has dropped significantly. At this time, the air volume of the range hood is reduced from the first air volume to the second air volume. The second preset time can be set according to actual conditions, for example, the second preset time can be set to 2 minutes, 3 minutes, 5 minutes, etc. Optionally, the exhaust component of the range hood can be turned off while the air volume of the air outlet component 4 is reduced from the second air volume to the first air volume. Alternatively, the exhaust assembly of the range hood may be turned off after the rotation speed of the air outlet assembly 4 of the range hood is reduced from the second air outlet volume to the first air outlet volume for a period of time.

[0056] Further, if Figure 1 and Figure 2 As shown, the housing 1 is provided with an opening, and the sensor matrix 3 is mounted in the opening of the housing 1. The sensor matrix 3 is plugged into the opening of the housing 1. Specifically, the housing 1 is provided with a socket, and the circuit board 31 of the sensor matrix 3 is provided with a plug-in portion, which plugs into the socket, thereby securing the sensor matrix 3 to the socket of the housing 1. In other embodiments, the sensor matrix 3 can be secured to the opening of the housing 1 by screws or by snap-fitting, as long as the sensor matrix 3 can be secured to the opening of the housing 1.

[0057] Further, if Figure 1 and Figure 2 As shown, the oil fume detection device of the present invention also includes a display module 5, which is mounted on the housing 1 and is used to display changes in the concentration of harmful substances in the air. The control module 2 is positioned above the range hood panel 11, and the display screen is positioned on the controller. The display module 5 is electrically connected to the sensor matrix 3. The main function of the display module 5 is to display changes in the concentration of harmful substances in the kitchen environment while the range hood is operating.

[0058] Further, if Figure 1 and Figure 2As shown, the air outlet assembly 4 includes a fan 41, which is located within the housing 1 and electrically connected to the control module 2. The control module 2 controls the air volume output of the fan 41 according to the concentration of different harmful substances. The housing 1 is provided with an air outlet 12 and an air inlet grille 13. The fan 41 draws air from the air inlet grille 13, and the air generated by the fan 41 flows out through the air outlet 12. When the range hood is turned on, the sensor matrix 3 is activated to identify harmful substances. Based on the type of harmful substance identified, the sensors 32 corresponding to unidentified harmful substances are deactivated, thereby saving energy and extending the service life of the sensors 32. The activated sensors 32 identify the concentration of harmful substances in the oil smoke and transmit the identification results to the range hood control module 2. The control module 2 controls the air volume of the air outlet assembly 4 according to the corresponding concentration thresholds for each harmful substance. When the harmful substance concentration exceeds a first preset value, the air volume of the air outlet assembly 4 is increased; when the harmful substance concentration is below the first preset value, the air volume of the air outlet assembly 4 is decreased. This effectively removes harmful substances while reducing the range hood's energy consumption. Air volume adjustment is based on the concentration of harmful substances in the fume, not the concentration of the fume itself. Frying, stir-frying, stir-frying, and pan-frying typically produce higher levels of harmful substances than steaming, simmering, boiling, and stewing. In this embodiment, the fume detection device also includes an exhaust assembly for discharging the fume outdoors.

[0059] An oil fume detection device in the present invention also includes a sound component, a temperature sensor module and a temperature output signal, and the control component and the sound component are electrically connected. The control component receives the temperature output signal of the temperature sensor module and the oil fume output signal of the image acquisition module respectively and sends a prompt signal to the sound component, and the sound component receives the prompt signal and sends a sound prompt. The sound of the present invention can be sound, music or voice prompt. Sound can represent different ambient air quality conditions with different rhythms or different sound lengths. Music can represent different ambient air quality conditions with different music. Voice prompts are to directly report the ambient air quality conditions. The user can be directly informed of the current ambient air quality conditions through sound prompts, thereby greatly improving the user's health protection.

[0060] At the same time, the sensor matrix 3 identifies the types and concentrations of harmful substances in the user's kitchen environment and records them for feedback to the control module 2 for storage, analysis, and graphical processing. The display module 5 displays real-time data based on the changes in the types and concentrations of harmful substances fed back by the sensor matrix 3, displaying harmful substance change trends. This allows the user to intuitively perceive changes in the air quality of the kitchen environment. The overall historical data set is used to generate a regional harmful substance database by region, which serves as user usage data to guide subsequent optimization of the sensor matrix. In this embodiment, the display module 5 can be integrated into the range hood's display screen or into the app of the kitchen appliance interconnection platform associated with the range hood.

[0061] An oil fume detection device in the present invention also includes a signal transmitting component, the control component and the signal transmitting component are electrically connected, and the signal transmitting component is connected to an external device by signal. The external device of the present invention is a mobile phone, a tablet computer, a household appliance or a cloud processor. The external device of this embodiment is specifically a mobile phone. The present invention can view various information detected by the prompt device by using an external device, and clearly display the current ambient air quality. The display method of the external device can be text, table or graphics, etc. This embodiment can send a prompt signal to the external device through the signal transmitting component, which can prompt the user of the current ambient air quality, thereby greatly improving the health protection of the user.

[0062] The present invention also provides a fume detection method applicable to the fume detection device described above. A sensor matrix 3 is provided on a housing 1. The sensor matrix 3 is used to detect different types of harmful substances in the fume. The method comprises the following steps: the sensor matrix 3 activates to identify harmful substances in the fume; the sensor determines whether the concentration of the harmful substances in the fume is greater than or equal to a first preset value; if the concentration of the harmful substances in the fume is greater than or equal to the first preset value, the control module 2 controls the air outlet assembly 4 to discharge air to clean the harmful substances in the fume. Compared to the prior art, where the sensor 32 can only detect a single type of harmful substance, the sensor 32 of this embodiment detects harmful substances, can identify multiple harmful substances, and can clean different types of fume, thereby achieving energy-saving effects and improving the user experience.

[0063] Furthermore, the sensor matrix 3 includes a plurality of sensors 32 , and the sensor matrix 3 starts to identify harmful substances in the oil smoke, including: each sensor 32 correspondingly detects one harmful substance in the oil smoke.

[0064] Furthermore, the sensor matrix 3 activates the identification of harmful substances in the oil smoke, and when a harmful substance is present in the oil smoke, a corresponding sensor 32 is activated for detection, and when no harmful substance is present in the oil smoke, the corresponding sensor 32 is deactivated. This achieves energy saving while extending the service life of the sensor 32.

[0065] Furthermore, the control module 2 controls the air outlet component 4 to discharge air, and at the same time or after cleaning the harmful substances in the oil smoke, the method also includes turning on the exhaust component and keeping it on for a certain period of time.

[0066] Furthermore, while or after the control module 2 controls the air outlet assembly 4 to discharge air and clean harmful substances in the oil smoke, the method further includes continuing to obtain the detected oil smoke concentration; if the concentration of harmful substances is greater than or equal to the first preset value, increasing the air volume of the air outlet assembly 4. Specifically, increasing the air volume of the air outlet assembly 4 includes, after a first preset time period, if the concentration of harmful substances is equal to the first preset value, increasing the air volume of the air outlet assembly 4 from the first air volume to the second air volume. After increasing the air volume of the air outlet assembly 4 from the first air volume to the second air volume, the method further includes, after a second preset time period, reducing the air volume of the air outlet assembly 4 from the second air volume to the first air volume.

[0067] Furthermore, at the same time as or after increasing the air volume of the air outlet assembly 4 from the first air volume to the second air volume, the method further includes shutting down the exhaust assembly of the range hood after the second preset time period has elapsed. After the second preset time period has elapsed, the concentration of harmful substances in the oil smoke decreases, and the exhaust assembly can be shut down.

[0068] The specific process of oil smoke detection of the present invention is as follows:

[0069] like Figure 3 As shown, after the range hood is started, the sensor matrix starts to identify harmful substances in the oil fume and judge the types of harmful substances in the oil fume. When harmful substances in the oil fume are identified, the sensor 32 in the sensor matrix is started accordingly. For harmful substances that do not appear in the oil fume, the sensor 32 in the sensor matrix is turned off accordingly, thereby achieving the effect of saving energy while extending the service life of the sensor 32.

[0070] The sensor 32 feeds back the data of the detected harmful substances to the control module 2, and the controller in the control module 2 determines the concentration of the harmful substances.

[0071] When the concentration of the harmful substance is greater than the first preset value, the controller controls the air outlet volume of the air outlet component 4 to the first air outlet volume, that is, the high-end position.

[0072] After the air outlet component 4 has been working for a period of time, the concentration of the harmful substance is detected again. When the concentration of the harmful substance is still greater than the first preset value, the controller controls the air outlet volume of the air outlet component 4 to the second air outlet volume, that is, a higher position, until the concentration of the harmful substance is less than the first preset value.

[0073] When the concentration of the harmful substance is less than the first preset value, the controller controls the air flow of the air outlet component 4 to a low position.

[0074] At the same time, during the detection process, the display module 5 displays the changes in the harmful substances so that the user can understand the situation of the harmful substances.

[0075] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
