Description

When the range hood is working, the flap is opened to collect smoke; when the range hood is not working, the flap is closed to ensure the overall aesthetics of the range hood. The flap of existing range hoods usually adopts a one-stage structure. If the one-stage flap is designed to be larger in order to ensure a better smoke collection effect, the flap will affect the user's operability during cooking when the flap is in a flipped state; if the one-stage flap is designed to be smaller in order to reduce the impact of the flipped flap on the user's operation, the range hood will have a poor oil smoke absorption effect.

[0052] Embodiment 1

[0053] like Figure 1 to Figure 3 As shown, the present embodiment provides an oil fume treatment device 1000, which may be a range hood, an integrated stove, etc. The present embodiment is described by taking a range hood as an example, the range hood comprises a main unit 300, a smoke collecting chamber body 200 and an air guide plate assembly 100, the smoke collecting chamber body 200 comprises a connected air inlet 210 and an inner cavity 220, the main unit 300 is arranged downstream of the smoke collecting chamber body 200 and is connected to the inner cavity 220, the air guide plate assembly 100 is arranged at the air inlet 210, and the air guide plate assembly 100 can open or block the air inlet 210.

[0054] like Figure 1 to Figure 3 As shown, when the range hood is working, the air guide plate assembly 100 is turned over and the air inlet 210 is opened, the main unit 300 is working and generates negative pressure, and the oil smoke outside the smoke collecting chamber body 200 can be discharged to the outside of the main unit 300 after passing through the air inlet 210, the inner cavity 220 and the main unit 300 in sequence, thereby realizing the range hood to absorb and discharge the oil smoke. Specifically, Figure 1 to Figure 3 As shown, the main unit 300 includes a shell 310 and a fan 320. The fan 320 is arranged in the shell 310. The shell 310 is arranged downstream of the smoke collecting chamber body 200, and the inner cavity 220 is connected with the interior of the shell 310. When the fan 320 is working, a negative pressure can be formed inside the shell 310, thereby achieving a better absorption effect of the range hood on external oil smoke.

[0055] like Figure 2 As shown, when the range hood is working, the air guide plate assembly 100 is opened to collect smoke; Figure 1 As shown, when the range hood is working, the air deflector assembly 100 is closed to ensure the overall aesthetics of the range hood. However, the air deflector assembly 100 of the existing range hood usually adopts a one-stage structure. If the one-stage air deflector assembly 100 is designed to be larger in order to ensure a better smoke collection effect of the air deflector assembly 100, when the air deflector assembly 100 is in a flipped state, the air deflector assembly 100 will affect the operability of the user during cooking; if the one-stage air deflector assembly 100 is designed to be smaller in order to reduce the impact of the flipped air deflector assembly 100 on the user's operation, the range hood will have a poor oil fume absorption effect. Therefore, the one-stage air deflector assembly 100 cannot be adaptively adjusted according to different working conditions or usage scenarios, and cannot achieve a relative balance between the oil fume absorption effect of the range hood and the good operability of the user.

[0056] To solve the above problems, Figure 1 to Figure 3 As shown, at least two air inlets 210 are provided on the smoke collecting chamber body 200, the air guide plate assembly 100 includes at least two air guide plates 10, at least two driving mechanisms 20 and an oil fume physical property detection device 30, at least two air guide plates 10 are hinged in sequence, an air guide plate 10 located at the end is hinged to the smoke collecting chamber body 200, each air guide plate 10 corresponds one-to-one to an air inlet 210, each air guide plate 10 corresponds one-to-one to a driving mechanism 20, the driving mechanism 20 can drive the corresponding air guide plate 10 to rotate so that the air guide plate 10 can block or open the corresponding air inlet 210, and the oil fume physical property detection device 30 is communicatively connected with the driving mechanism 20 and is used to detect the physical property information of the oil fume. Each driving mechanism 20 can adjust its respective working state according to the physical property information of the oil fume (different working conditions or usage scenarios) to adjust the state of each air guide plate 10 to adapt to different working conditions or usage scenarios. The air guide plate assembly 100 of the disclosed embodiment can be adaptively adjusted according to different working conditions or usage scenarios to achieve a relative balance between the oil fume suction effect of the range hood and good operability for the user.

[0057] Exemplarily, the range hood further includes a controller, and the oil fume property detection device 30 and the driving mechanism 20 are both communicatively connected to the controller, wherein the communication connection may be an electrical connection via a wire, or may be a signal transmission such as an infrared signal, a WIFI signal, or the like.

[0058] It should be noted that when in a low smoke environment, Figure 2As shown, there are fewer air guide plates 10 in a flipped state from bottom to top, and a part of the air guide plates 10 are in a non-flipped state. There are relatively fewer open air inlets 210, and the total area of ​​the open air inlets 210 is relatively small. The air guide plate assembly 100 in this state occupies less operating space for the user, and while meeting the normal oil fume absorption effect, it can also ensure better operability for the user.

[0059] It should be noted that when in a high smoke environment, Figure 3 As shown, there are relatively more air deflectors 10 in a flipped state from bottom to top, which can increase the smoke collecting area space of the air deflector assembly 100 and the smoke collecting angle of the air deflector assembly 100, and there are relatively more open air inlets 210, and the total area of ​​the open air inlets 210 is relatively large, thereby achieving a better oil smoke absorbing effect for high oil smoke. In addition, the air deflector assembly 100 in this working condition is generally convex toward the air inlet 210, and a larger operating space can be formed above the air deflector assembly 100, ensuring better operability for users.

[0060] In summary, regardless of the low oil fume environment state or the high oil fume environment state, the overall shape of the air guide plate assembly 100 of the embodiment of the present disclosure can be adapted to different working conditions or usage scenarios, so as to achieve a relative balance between the oil fume absorption effect of the range hood and the user's good operability.

[0061] In an optional embodiment, if Figure 1 to Figure 3 As shown, one of the driving mechanisms 20 is a first driving mechanism 21, and the other driving mechanisms 20 are second driving mechanisms 22. Two adjacent air guide plates 10 are connected via the second driving mechanism 22. The first driving mechanism 21 can drive the air guide plate 10 hinged to the smoke collecting chamber body 200 to rotate relative to the smoke collecting chamber body 200, and the second driving mechanism 22 can drive the two adjacent air guide plates 10 to rotate relative to each other. Through the mutual cooperation of the first driving mechanism 21 and the second driving mechanism 22, at least two air guide plates 10 can be constructed into shapes that are compatible with corresponding working conditions or usage scenarios. Among them, the more the number of air guide plates 10, the more different shapes of the air guide plate assembly 100 that can be adjusted, and the stronger the ability of the air guide plate assembly 100 to adapt to different working conditions or usage scenarios.

[0062] In an optional embodiment, if Figure 1 to Figure 3As shown, the first driving mechanism 21 includes a first driving body 211 and a first output shaft 212 that can make a linear motion relative to the first driving body 211, the first driving body 211 is hinged to the smoke collecting chamber body 200, and the wind guide plate 10 hinged to the smoke collecting chamber body 200 is hinged to the first output shaft 212. When the first output shaft 212 is extended relative to the first driving body 211, the first output shaft 212 can apply a thrust to the wind guide plate 10 hinged to the smoke collecting chamber body 200, so that the wind guide plate 10 hinged to the smoke collecting chamber body 200 is flipped outward and opened, thereby exposing the air inlet 210 corresponding to the wind guide plate 10 hinged to the smoke collecting chamber body 200.

[0063] In an optional embodiment, the air guide plate 10 hinged to the smoke collecting chamber body 200 can be hinged to the smoke collecting chamber body 200 through a first hinge 500, a rotating shaft, etc., which has a simple structure and is easy to assemble. All structures that can achieve a rotatable connection between two adjacent air guide plates 10 are within the protection scope of the embodiments of the present disclosure.

[0064] In an optional embodiment, two adjacent air guide plates 10 can be hinged by a second hinge 50, a rotating shaft, a connecting rod, etc. The structure is simple and easy to assemble. All structures that can realize the rotational connection of two adjacent air guide plates 10 are within the protection scope of the disclosed embodiment.

[0065] In an optional embodiment, if Figure 1 to Figure 3 As shown, the second driving mechanism 22 includes a rotary driving mechanism 221 and a connecting rod assembly 222. The rotary driving mechanism 221 includes a fourth driving body 2211 and a fourth output shaft 2212 rotatably connected thereto. The fourth driving body 2211 is disposed on one of the two adjacent air deflectors 10. One end of the connecting rod assembly 222 is fixedly connected to the fourth output shaft 2212, and the other end of the connecting rod assembly 222 is hinged to the other of the two adjacent air deflectors 10. When the rotary driving mechanism 221 is working, the fourth output shaft 2212 rotates, and the fourth output shaft 2212 drives the connecting rod assembly 222 to move. The connecting rod assembly 222 can make the other of the two adjacent air deflectors 10 rotate around the rotating shaft of the second hinge 50. Specifically, the second driving mechanism 22 can be a rotary motor with a self-locking function. When the fourth output shaft 2212 is adjusted to a corresponding state, the rotary motor can be self-locked, so that the two adjacent air deflectors 10 with adjusted postures can be locked, and the postures of the two air deflectors 10 with adjusted postures are kept unchanged.

[0066] Specifically, if Figure 1 to Figure 3As shown, the connecting rod assembly 222 includes a first connecting rod 2221 and a second connecting rod 2222, and the fourth output shaft 2212 is fixedly connected to one end of the first connecting rod 2221, and the other end of the first connecting rod 2221, the first connecting rod 2221, the second connecting rod 2222 and the other of the two adjacent air guide plates 10 are hinged in sequence. Through the connecting rod assembly 222 of the aforementioned structure, the fourth output shaft 2212 only rotates a small angle, and through the transmission action of the connecting rod assembly 222, the two adjacent air guide plates 10 can be rotated at a larger angle, and the postures of the two adjacent air guide plates 10 can be quickly and accurately adjusted.

[0067] In an optional embodiment, if Figure 1 to Figure 3 As shown, the fourth output shaft 2212 includes a protrusion 22121, and a slot 22211 is opened on the first connecting rod 2221. The slot 22211 is adapted to the protrusion 22121, and the protrusion 22121 is inserted into the slot 22211. The cross-section of the protrusion 22121 and the cross-section of the slot 22211 are non-circular, which can avoid the rotation of the protrusion 22121 relative to the slot 22211, thereby preventing the fourth output shaft 2212 and the first connecting rod 2221 from rotating relative to each other.

[0068] For example, Figure 1 to Figure 3 As shown, the cross-section of the protrusion 22121 and the cross-section of the slot 22211 can be elliptical, semicircular, polygonal, irregular, etc. All corresponding shapes that can prevent the fourth output shaft 2212 and the first connecting rod 2221 from rotating relative to each other are within the protection scope of this optional embodiment.

[0069] In other embodiments, the first connecting rod 2221 may include a protrusion 22121, and a slot 22211 may be provided on the fourth output shaft 2212. The slot 22211 is adapted to the protrusion 22121, and the protrusion 22121 is inserted into the slot 22211. The cross-section of the protrusion 22121 and the cross-section of the slot 22211 are non-circular, which can also achieve the above-mentioned effect.

[0070] In an optional embodiment, if Figure 1 to Figure 3 As shown, the oil fume physical property detection device 30 includes a first oil fume physical property detection mechanism 31, which is located on the side of the air guide plate 10 facing the inner cavity 220 of the smoke collecting chamber main body 200. When the air guide plate 10 is in an open state, the first oil fume physical property detection mechanism 31 is directly opposite to the oil fume, and the first oil fume physical property detection mechanism 31 can realize accurate detection of the physical property information of the oil fume.

[0071] In an optional embodiment, if Figure 1 to Figure 3As shown, the first oil fume property detection mechanism 31 is disposed on the inner side of the lowest air guide plate 10, so that the air guide plate assembly 100 in the open state can detect the oil fume in a timely and accurate manner. In addition, by disposing the first oil fume property detection mechanism 31 on the lowest air guide plate 10, it is convenient for users to quickly repair and replace the first oil fume property detection mechanism 31.

[0072] In an optional embodiment, the first oil fume physical property detection mechanism 31 includes at least one of a first oil fume concentration detection mechanism, a first oil fume flow rate detection mechanism, a first oil fume flow rate detection mechanism and a first oil fume temperature detection mechanism, wherein the first oil fume concentration detection mechanism can detect the concentration information of the oil fume, the first oil fume flow rate detection mechanism can detect the flow rate information of the oil fume, the first oil fume flow rate detection mechanism can detect the flow rate information of the oil fume, and the first oil fume temperature detection mechanism can detect the temperature information of the oil fume. By detecting the concentration information, flow rate information, flow rate information or temperature information of the oil fume, the environmental information of the usage scenario and the working condition information that the range hood needs to adapt can be accurately determined.

[0073] In an optional embodiment, if Figure 1 to Figure 3 As shown, the oil fume physical property detection device 30 also includes a second oil fume physical property detection mechanism 32, which is located on the side of the air guide plate 10 away from the inner cavity 220 of the smoke collecting chamber main body 200. When the air guide plate 10 is in a state of blocking the air inlet 210, the second oil fume physical property detection mechanism 32 is directly opposite to the oil fume, and the second oil fume physical property detection mechanism 32 can realize accurate detection of the physical property information of the oil fume.

[0074] In an optional embodiment, if Figure 1 to Figure 3 As shown, the second oil fume property detection mechanism 32 is arranged on the side of the lowest air guide plate 10 away from the inner cavity 220 of the smoke collecting chamber body 200. The second oil fume property detection mechanism 32 is closer to the oil fume. When the air guide plate assembly 100 is in a closed state, the second oil fume property detection mechanism 32 can detect the oil fume in a timely and accurate manner. In addition, by arranging the second oil fume property detection mechanism 32 on the lowest air guide plate 10, it is convenient for users to quickly repair and replace the second oil fume property detection mechanism 32.

[0075] In an optional embodiment, the second oil fume physical property detection mechanism 32 includes at least one of a second oil fume concentration detection mechanism, a second oil fume flow rate detection mechanism, a second oil fume flow rate detection mechanism and a second oil fume temperature detection mechanism, wherein the second oil fume concentration detection mechanism can detect the concentration information of the oil fume, the second oil fume flow rate detection mechanism can detect the flow rate information of the oil fume, the second oil fume flow rate detection mechanism can detect the flow rate information of the oil fume, and the second oil fume temperature detection mechanism can detect the temperature information of the oil fume. By detecting the concentration information, flow rate information, flow rate information or temperature information of the oil fume, the environmental information of the usage scenario and the working condition information that the range hood needs to adapt can be accurately determined.

[0076] In an optional embodiment, the fan 320 is connected to the oil fume physical property detection device 30 for communication, and the fan 320 can adjust its own gear according to the physical property information of the oil fume detected by the oil fume physical property detection device 30, so as to realize the adaptive adjustment of the gear of the fan 320 and the oil fume intensity, and can realize a better oil fume absorbing effect for oil fume of different intensities. For example, when the detected physical property information indicates that the oil fume is weak, the fan 320 is adjusted to a weak gear; when the detected physical property information indicates that the oil fume is moderate, the fan 320 is adjusted to a strong gear; when the detected physical property information indicates that the oil fume is strong, the fan 320 is adjusted to a stir-fry gear. Specifically, the fan 320 is also connected to the controller for communication. By adjusting the number of openings of the air inlet 210 and adjusting the gear of the fan 320, it is possible to match the working mode of the range hood that meets more different working conditions, and the range hood is better and more flexible in adapting to different usage scenarios.

[0077] In order to explain the working process of the range hood, Figure 1 to Figure 3 As shown, the structure of the air guide plate assembly 100 including two air guide plates 10 is described, wherein the smoke collecting chamber body 200, the upper air guide plate 10 and the lower air guide plate 10 are hinged in sequence, the first oil fume physical property detection mechanism 31 is selected as the first oil fume concentration detection mechanism, and the second oil fume physical property detection mechanism 32 is selected as the second oil fume concentration detection mechanism. Figure 4 As shown, the specific control process is:

[0078] When the range hood is in Figure 1 In the state shown, the upper air guide plate 10 and the lower air guide plate 10 respectively block the corresponding air inlet 210, and the range hood is in the off state. The second oil fume concentration detection mechanism obtains the first oil fume concentration detection value C 检测1 and transmitted to the controller, which converts the first oil smoke concentration detection value C 检测1 With the first preset value C 预设1 In comparison: If C 检测1 ≥C 预设1 ,like Figure 2As shown, the controller controls the fourth output shaft 2212 to rotate, and the fourth output shaft 2212 drives the first connecting rod 2221 and the second connecting rod 2222 to work in conjunction, so that the wind guide plate 10 at the lower end rotates clockwise relative to the smoke collecting chamber body 200, and only the wind guide plate 10 at the lower end opens the corresponding air inlet 210, and the smoke can be smoked only through the lower air inlet 210. In addition, the fan 320 is switched to a low gear, and the opening of the lower air inlet 210 and the cooperation of the low-smoke fan 320 can fully absorb the smoke in the low-smoke environment; if C 检测1 <C 预设1 , it means that the amount of oil smoke is small, the range hood does not need to be started temporarily, and the second oil smoke concentration detection mechanism continues to obtain the first oil smoke concentration detection value C 检测1 .

[0079] After the wind guide plate 10 at the lower end is opened and the fan 320 is switched to the low gear, the first oil fume concentration detection mechanism faces the oil fume, and the first oil fume concentration detection mechanism obtains the second oil fume concentration detection value C 检测2 and transmitted to the controller, which converts the second oil smoke concentration detection value C 检测2 With the second preset value C 预设2 In comparison, C 预设2 >C 预设1 :If C 检测2 ≥C 预设2 ,like Figure 3 As shown, the controller controls the first output shaft 212 to extend relative to the first driving body 211, and the first output shaft 212 can drive the upper wind guide plate 10 to rotate clockwise relative to the smoke collecting chamber body 200, and the upper wind guide plate 10 and the lower wind guide plate 10 respectively open the corresponding air inlets 210, and the oil smoke can be sucked out through the two air inlets 210, and the two air inlets 210 can fully absorb the oil smoke with a medium amount of oil smoke; if C 检测2 <C 预设2 The first oil fume concentration detection mechanism continues to obtain the second oil fume concentration detection value C 检测2 .

[0080] After the upper air guide plate 10 and the lower air guide plate 10 are both opened, the controller sets the second oil smoke concentration detection value C 检测2 With the third preset value C 预设3 In comparison, C 预设3 >C 预设2 :If C 检测2 ≥C 预设3 , the fan 320 is switched to the stir-frying gear, and the cooperation between the two air inlets 210 and the stir-frying gear fan 320 can fully absorb the oil smoke with a high amount of oil smoke; if C 检测2 <C 预设3, the fan 320 is switched to a high gear, and the cooperation between the two air inlets 210 and the high gear fan 320 can fully absorb the medium amount of oil smoke.

The structures of the air deflector assembly 100 and the oil fume treatment device 1000 are substantially the same as those of the air deflector assembly 100 and the oil fume treatment device 1000 of the first embodiment. The main difference between the two is that the structure of the first driving mechanism 21 is different, such as Figure 5 As shown, the air guide plate 10 hinged to the smoke collecting chamber body 200 includes a first air guide plate body 11 and a first rotating shaft 12 that are fixedly connected. The first rotating shaft 12 is hinged to the smoke collecting chamber body 200. The first driving mechanism 21 includes a second driving body 213 and a second output shaft 214 that is rotatably connected thereto. The second driving body 213 is fixedly connected to the smoke collecting chamber body 200. The second output shaft 214 can drive the first rotating shaft 12 to rotate.

In addition, since the second driving body 213 will not flip back and forth during use, it can ensure a longer service life of the range hood during use.

Exemplarily, the number of bearings 17 can be one, two, three, four or more, and when the number of bearings 17 is set to at least two, more bearings 17 can achieve stable support for the first rotating shaft 12.

When the second output shaft 214 rotates, the second output shaft 214 can drive the second transmission wheel 42 to rotate, and the second transmission wheel 42 can drive the annular conveyor belt and the first transmission wheel 41 to rotate, thereby realizing the rotation of the first rotating shaft 12, thereby realizing the rotation of the air guide plate 10 hinged to the smoke chamber body 200. The transmission assembly 40 of this structure runs smoothly, is simple to operate, easy to repair, relatively convenient to use and maintain, has good flexibility, can mitigate impact and absorb vibration, and has low noise in use. It should be noted that all transmission assemblies 40 of other structures that can realize the transmission of the second output shaft 214 and the first rotating shaft 12 are within the protection scope of the embodiments of the present disclosure.
