[0039] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0040] Currently, cooking fumes are typically extracted outdoors through a range hood. The exhaust performance of a range hood depends on the pressure differential across the fan. Improving the hood's fume extraction capacity requires increasing the pressure differential across the fan.

[0041] However, while the oil fume extraction capacity is improved, the operating noise of the range hood will also increase. For example, the main cause of the noise of the range hood is the friction between the high-speed rotating fan blades and the oil fume-laden air.

[0042] Based on the above technical problems, the present utility model is proposed. The utility model may include a main oil fume duct 1, at least one slave oil fume duct 2, a smoke exhaust device 3 and a smoke exhaust fan 4. The main oil fume duct 1 is in air communication with the slave oil fume duct 2. The smoke exhaust device 3 is located at one end of the slave oil fume duct 2 away from the main oil fume duct 1 and is in air communication with the slave oil fume duct 2, wherein the smoke exhaust device 3 is located in the oil fume generating area. The smoke exhaust fan 4 is located at the top end of the main oil fume duct 1 so as to extract the oil fume located in the oil fume generating area through the operation of the smoke exhaust fan 4. In this way, the smoke exhaust fan 4 that generates loud noise during smoke exhaust can be moved away from the user environment. By sharing a high-power smoke exhaust fan 4 at the remote end, the smoke exhaust noise can be greatly reduced while ensuring the oil suction effect.

[0043] Reference Figure 1-5The present invention provides an oil fume treatment device, which may include a main oil fume duct 1, at least one secondary oil fume duct 2, a smoke exhaust device 3, and a smoke exhaust fan 4. The main oil fume duct 1 is in air communication with the secondary oil fume duct 2. The smoke exhaust device 3 is located at an end of the secondary oil fume duct 2 away from the main oil fume duct 1 and is in air communication with the secondary oil fume duct 2. The smoke exhaust device 3 is located in an oil fume generating area. The smoke exhaust fan 4 is located at the top end of the main oil fume duct 1 so that the smoke exhaust fan 4 can be used to extract the oil fume in the oil fume generating area.

[0044] In an embodiment of the present invention, the oil fume treatment device may include a main oil fume duct 1, at least one secondary oil fume duct 2, a smoke exhaust device 3, and a smoke exhaust fan 4. The smoke exhaust fan 4 may be a high-power, high-static-pressure fan. The main oil fume duct 1 is installed vertically, and the smoke exhaust fan 4 is mounted at the top of the main oil fume duct 1. This allows the smoke exhaust fan 4 to exhaust the oil fume in the main oil fume duct 1 out of the main oil fume duct 1 when it is in operation.

[0045] There can be multiple oil fume ducts 2, and those skilled in the art can determine the number of the oil fume ducts 2 based on the application scenario designed for the oil fume treatment device. In some examples, if the oil fume treatment device is used in a multi-story residential building, the number of the oil fume ducts 2 is adapted to the total number of residences in the corresponding high-rise residential building, so that the oil fume generating area (such as the kitchen area) of each household is installed with one oil fume duct 2. In other examples, if the oil fume treatment device is used in residential houses or villa buildings, the number of the oil fume ducts 2 is consistent with the planned number of oil fume generating areas in the residential houses or villa buildings. The number of the oil fume ducts 2 is not excessively limited here.

[0046] The smoke exhaust device 3 is located at the end of the secondary oil fume duct 2 away from the main oil fume duct 1, that is, installed in the oil fume generating area. The main oil fume duct 1 is in air communication with the secondary oil fume duct 2, and the secondary oil fume duct 2 is in air communication with the smoke exhaust device 3. Thus, when the smoke exhaust fan 4 is in operation, it can draw oil fume in the oil fume generating area into the smoke exhaust device 3, which then flows through the smoke exhaust device 3 into the secondary oil fume duct 2, and finally into the main oil fume duct 1 and is discharged outdoors. This eliminates the need for a fan in the oil fume generating area, such as the user's kitchen area, and allows the smoke exhaust fan 4, which generates loud exhaust noise, to be located away from the user's environment. Furthermore, by sharing a single smoke exhaust fan 4 with multiple secondary oil fume ducts 2, the smoke exhaust noise can be significantly reduced while ensuring effective oil extraction, thereby improving the user experience.

[0047] In summary, the embodiment of the present invention may include a main oil fume duct 1, at least one slave oil fume duct 2, a smoke exhaust device 3 and a smoke exhaust fan 4, wherein the main oil fume duct 1 is in air communication with the slave oil fume duct 2. The smoke exhaust device 3 is located at one end of the slave oil fume duct 2 away from the main oil fume duct 1, and is in air communication with the slave oil fume duct 2, wherein the smoke exhaust device 3 is located in the oil fume generating area. The smoke exhaust fan 4 is located at the top end of the main oil fume duct 1, so that the smoke located in the oil fume generating area can be extracted through the operation of the smoke exhaust fan 4. In this way, the smoke exhaust fan 4 that generates loud noise during smoke exhaust can be moved away from the user environment, and by sharing a high-power smoke exhaust fan 4 at the remote end, the smoke exhaust noise can be greatly reduced while ensuring the oil suction effect.

[0048] In some optional embodiments, those skilled in the art can determine the pressure head of the smoke exhaust fan 4 based on actual design requirements. Pressure head refers to the static pressure of the smoke exhaust fan 4, which represents the amount of static pressure that the smoke exhaust fan 4 can generate per unit time, and the unit is usually Pa (Pascal). For example, the total height of the main fume duct 1 is h, and only one smoke exhaust fan 4 is installed. Then the pressure head of the smoke exhaust fan 4 is at least:

[0049] P=pgh+P formula (1)

[0050] In the above formula (1), P is the pressure head of the exhaust fan 4; ρ is the density of the oil smoke; g is the acceleration of gravity; h is the total height of the main oil smoke duct 1; and p is the minimum exhaust pressure difference at the lowest point of the main oil smoke duct 1. The minimum exhaust pressure difference at the lowest point of the main oil smoke duct 1 can be understood as the difference between the pressure head of the exhaust fan 4 and the pressure at the lowest point of the main oil smoke duct 1 when the exhaust fan 4 is just able to exhaust the oil smoke.

[0051] An optional embodiment of the utility model, the smoke exhaust device 3 includes a smoke exhaust panel 31 and a smoke exhaust shell 32, the smoke exhaust duct 2 extends into the smoke exhaust shell 32, the smoke exhaust panel 31 is installed on the smoke exhaust shell 32, and cooperates with the smoke exhaust shell 32 to form a smoke outlet 301, so that the smoke in the smoke generating area enters the smoke exhaust duct 2 through the smoke outlet 301.

[0052] In this embodiment of the present invention, the smoke exhaust device 3 may include a smoke exhaust panel 31 and a smoke exhaust housing 32. The appearance of the smoke exhaust panel 31 and the smoke exhaust housing 32 can be consistent with the appearance of the range hood. The smoke exhaust duct 2 extends into the smoke exhaust housing 32, and the smoke exhaust panel 31 is mounted on the smoke exhaust housing 32 and cooperates with the smoke exhaust housing 32 to form a smoke outlet 301. For example, the smoke exhaust panel 31 is located in the middle area of ​​the smoke exhaust housing 32, forming a smoke outlet 301 surrounding the smoke exhaust panel 31.

[0053] The smoke exhaust fan 4 located in the main oil fume duct 1 generates wind pressure when working, sucking the oil fume in the oil fume generating area into the smoke outlet 301, and flowing into the secondary oil fume duct 2 through the smoke outlet 301, and then flowing from the main oil fume duct through the smoke exhaust fan 4, and discharged outside the main oil fume duct 1.

[0054] An optional embodiment of the utility model, referring to Figure 2 As shown, the smoke exhaust panel 31 is arranged at an angle to the vertical direction line.

[0055] In this embodiment of the present invention, the exhaust panel 31 is arranged at an angle to the vertical, which can also be understood as being tilted. Accordingly, the exhaust panel 31 can be positioned above the stovetop to facilitate the passage of cooking fumes from the smoke outlet 301 into the exhaust housing 32. The tilted exhaust panel 31 allows the smoke outlet 301 to be tilted, improving the efficiency of cooking fumes entering the exhaust housing 32.

[0056] An optional embodiment of the utility model, referring to Figure 2 and Figure 5 As shown, the smoke exhaust device 3 may further include a drive assembly 33 and a baffle 34. The drive assembly 33 is fixed in the secondary oil fume duct 2. The baffle 34 is in driving connection with the drive assembly 33. A smoke exhaust port 3301 is formed between the baffle 34 and the secondary oil fume duct 2. When the drive assembly 33 is in operation, it drives the baffle 34 to rotate to adjust the exhaust flow rate of the smoke exhaust port 3301.

[0057] In an embodiment of the present utility model, the smoke exhaust device 3 may further include a drive assembly 33 and a baffle 34. The drive assembly 33 is used to output a rotational force and drive the baffle 34 to rotate. The drive assembly 33 is fixed in the oil fume duct 2, and the baffle 34 is transmission-connected (also referred to as a rotational connection) to the drive assembly 33. A smoke exhaust port 3301 is formed between the baffle 34 and the oil fume duct 2. When the drive assembly 33 is working, it drives the baffle 34 to rotate, so that the opening of the baffle 34 can be adjusted by rotating the baffle 34. In this way, the smoke exhaust flow rate of the smoke exhaust port 3301 can be adjusted by rotating the baffle 34 forward and backward.

[0058] In some embodiments, the driving component 33 may be an electric driving component 33, and the smoke exhaust device 3 may further include a control switch, which may be embedded in the power supply circuit of the driving component 33, so that the rotation angle of the baffle 34 can be adjusted by controlling the on and off of the power supply circuit.

[0059] An optional embodiment of the utility model, referring to Figure 5 As shown, the driving assembly 33 may include a motor 331 and a rotating shaft 332. The motor 331 is fixed in the secondary oil fume duct 2. The rotating shaft 332 is rotatably connected to the secondary oil fume duct 2 and is coaxially fixed with the output shaft of the motor 331. The rotating shaft 332 is fixedly connected to the baffle 34 so that the baffle 34 is driven to rotate by the operation of the motor 331.

[0060] In an embodiment of the present utility model, the drive assembly 33 may include a motor 331 and a rotating shaft 332, wherein the motor 331 is used to output rotational motion. The motor 331 may be fixed in the oil fume duct 2, and the output shaft of the motor 331 and the rotating shaft 332 may be coaxially fixed. The rotating shaft 332 may be rotationally connected to the oil fume duct 2 through components such as a bearing seat. The rotating shaft 332 is coaxially fixed with the output shaft of the motor 331, which can be understood as the central axis of the rotating shaft 332 coinciding with the central axis of the output shaft of the motor 331, and the rotating shaft 332 is fixedly connected to the output shaft of the motor 331. The rotating shaft 332 and the output shaft of the motor 331 may be fixed by welding, a coupling, or the like.

[0061] When the motor 331 rotates, it drives the rotating shaft 332 fixed to the output shaft of the motor 331 to rotate synchronously. The rotating shaft 332 rotates and drives the baffle 34 fixed to the rotating shaft 332 to rotate, thereby controlling the exhaust flow from the oil fume duct 2 by adjusting the opening of the baffle 34.

[0062] An optional embodiment of the utility model, referring to Figure 2 As shown, the oil fume treatment equipment may further include at least two temperature and pressure sensors 5 , at least two of which are located in the oil fume duct 2 and distributed on both sides of the exhaust port 3301 to detect the temperature and pressure values ​​on both sides of the exhaust port 3301 .

[0063] In the embodiment of the present invention, the temperature and pressure sensor 5 refers to a sensor that can detect temperature and pressure simultaneously. The oil fume treatment device includes at least two temperature and pressure sensors 5, and at least two temperature and pressure sensors 5 are installed in the oil fume duct 2 and distributed on both sides of the exhaust port 3301. In other words, at least one temperature and pressure sensor 5 is provided on each side of the exhaust port 3301 to detect the temperature and pressure values ​​on both sides of the exhaust port 3301. Therefore, the exhaust flow rate through the exhaust port 3301 can be calculated based on the difference in temperature and pressure values ​​on both sides of the exhaust port 3301.

[0064] Those skilled in the art can determine the specific number of temperature and pressure sensors 5 based on actual design requirements, and are not limited here. For example, two temperature and pressure sensors 5 can be provided, with one temperature and pressure sensor 5 provided on each side of the smoke exhaust port 3301. For another example, four temperature and pressure sensors 5 can be provided, with two temperature and pressure sensors 5 provided on each side of the smoke exhaust port 3301. This ensures that even if one of the temperature and pressure sensors 5 on one side of the smoke exhaust port 3301 fails, the temperature and pressure values ​​on that side can still be detected normally.

[0065] An optional embodiment of the utility model, referring to Figure 3 As shown, the oil fume treatment device may further include a controller 6 , which is electrically connected to at least two of the temperature and pressure sensors 5 to receive temperature values ​​and pressure values ​​from the temperature and pressure sensors 5 .

The oil fume treatment device may also include at least two pressure sensors, at least two of which are installed in the oil fume duct 2 and distributed on both sides of the exhaust port 3301. In other words, at least one pressure sensor is provided on each side of the exhaust port 3301 to detect the pressure values ​​on both sides of the exhaust port 3301. Therefore, the exhaust flow rate through the exhaust port 3301 can be evaluated by the difference in pressure values ​​on both sides of the exhaust port 3301.

[0070] Those skilled in the art can determine the specific number of pressure sensors based on actual design requirements, and this is not limited here. For example, two pressure sensors can be provided, with one pressure sensor provided on each side of the smoke exhaust port 3301. For another example, four pressure sensors can be provided, with two pressure sensors provided on each side of the smoke exhaust port 3301. This ensures that even if one of the pressure sensors on one side of the smoke exhaust port 3301 fails, the pressure value on that side can still be detected normally.

In other words, at least one temperature sensor is provided on each side of the exhaust port 3301 to detect the temperature and pressure values ​​on both sides of the exhaust port 3301. Therefore, the exhaust flow rate through the exhaust port 3301 can be calculated based on the difference in temperature and pressure values ​​on both sides of the exhaust port 3301.

[0073] Those skilled in the art can determine the specific number of temperature sensors based on actual design requirements, and this is not limited here. For example, two temperature sensors can be provided, with one temperature sensor provided on each side of the exhaust port 3301. For another example, four temperature sensors can be provided, with two temperature sensors provided on each side of the exhaust port 3301. This ensures that even if one temperature sensor on one side of the exhaust port 3301 fails, the temperature value on that side can still be detected normally.

[0074] In an optional embodiment of the utility model, the oil fume treatment device may further include a controller 6, and the controller 6 is electrically connected to at least two of the pressure sensors and at least two of the temperature sensors, respectively, to receive the pressure values ​​of the pressure sensors and the temperature values ​​of the temperature sensors.

[0076] In the above embodiment of the utility model, the total smoke exhaust volume of the user in a period of time can be determined by calculating the exhaust flow rate through the exhaust port 3301. Therefore, the user's usage cost is proportional to the exhaust volume, and the exhaust fee of the oil fume treatment device can be converted.

[0077] An optional embodiment of the utility model, referring to Figure 1 As shown, the oil fume treatment equipment further includes a backup fan 7 arranged on the main oil fume duct 1.

[0078] In the embodiment of the present invention, the oil fume treatment device may further include a backup fan 7, which is installed on the main oil fume duct 1.

[0079] In some optional embodiments, the backup fan 7 and the smoke exhaust fan 4 are spaced apart along the axial direction of the main oil fume duct 1. For example, the backup fan 7 can be located below the smoke exhaust fan 4, or above the smoke exhaust fan 4. Those skilled in the art can determine the vertical positional relationship between the backup fan 7 and the smoke exhaust fan 4 based on actual design requirements, and no further limitations are imposed herein.

[0080] In each of the above-mentioned utility model embodiments, the secondary oil fume duct 2 may include a first pipe portion and a second pipe portion in air communication with the first pipe portion. The first pipe portion is in air communication with the primary oil fume duct 1. The first pipe portion may be made of metal to facilitate installation of the temperature and pressure sensor 5, the drive assembly 33, or the temperature and pressure sensors. The second pipe portion may be a flexible tube made of aluminum foil or other materials, extending into the exhaust housing 32, thereby facilitating installation of the secondary oil fume duct 2.
