Description

Technical Field

[0001] This utility model relates to an oil fume purification device, and more particularly to an oil fume extractor. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It can quickly remove waste from the stove and fumes produced during cooking and exhaust them outdoors, reducing pollution and purifying the air.

[0003] For example, Chinese utility model patent application number 202220631630.9 discloses a range hood, which includes a range hood body and a flap. A smoke collection hood is provided on the front side of the range hood body. The top of the flap is hinged to the range hood body and the flap is located outside the smoke collection hood. The smoke collection hood has a recess and an air inlet is provided at the bottom of the recess.

[0004] Most range hoods nowadays are wall-mounted, with the entire unit positioned diagonally above the cooktop. Because the range hood's smoke collection hood has a certain width, a dead zone is formed between the bottom of the hood and the wall. This area is far from the air inlet, making it prone to vortex formation, causing cooking fumes to swirl and float in this area. This not only reduces the range hood's smoke extraction effect and efficiency but also results in a poor user experience and aesthetics. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a range hood that can solve the problem of vortex in the dead corner area between the bottom of the smoke collection hood and the wall, and guide the oil fumes in that area to the smoke inlet.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a range hood, including a smoke collection hood, wherein a smoke inlet is provided on the front side of the smoke collection hood, characterized in that: the range hood further includes a guide plate assembly capable of guiding the oil fumes below the bottom of the smoke collection hood to the smoke inlet, wherein the guide plate assembly can be in a first state hidden inside the smoke collection hood and a second state at least partially exposed at the bottom of the smoke collection hood.

[0007] By setting up a baffle assembly, the problem of vortex flow in the dead corner area between the bottom of the fume hood and the wall can be solved, and the oil fumes in this area can be directed to the smoke inlet. The baffle assembly can also be hidden when the machine is off.

[0008] In order to drive the baffle assembly to move, the range hood also includes a motion mechanism capable of driving the baffle assembly to move.

[0009] To drive the flow guide plate assembly to move, the motion mechanism includes a drive device, rollers, and a bracket. The drive device is located inside the smoke hood and includes a rotating output shaft connected to the rotation center of the rollers. The rollers are driven to rotate by the output shaft. The bracket is rotatably mounted on the output shaft. The flow guide plate assembly includes a flow guide plate body, which is positioned between the bracket and the rollers. The rollers abut against the flow guide plate body, and the flow guide plate body is moved by the rollers. The inner side of the smoke hood is provided with guide grooves that can guide and limit the flow guide plate body. The guide grooves are longitudinally arranged on the left and right sides of the flow guide plate body.

[0010] In order to limit the position of the guide plate body, the bracket includes a connecting part and a snap-fit ​​part. One end of the connecting part is rotatably connected to the output shaft, and the other end of the connecting part is connected to the snap-fit ​​part. The snap-fit ​​part is located on the side of the guide plate body away from the roller, and the guide plate body is limited between the roller and the snap-fit ​​part.

[0011] To prevent the deflector body from detaching from the bracket and rollers when it moves downward, the deflector assembly also includes an anti-detachment part that prevents the deflector body from detaching from the rollers and the locking part when it moves downward. The anti-detachment part is located on the top of the deflector body and can be locked with the locking part.

[0012] In order to achieve a better flow guiding effect, after the anti-detachment part and the snap-fit ​​part are snapped together, the roller can drive the main body of the flow guide plate to tilt forward.

[0013] To enable smoother movement of the air deflector assembly, two motion mechanisms are provided, symmetrically arranged on the left and right sides of the air deflector body.

[0014] In order to achieve the effect of noise reduction, noise reduction holes are provided on the main body of the guide plate, and sound-absorbing cotton is provided on the back side of the main body of the guide plate.

[0015] Compared with existing technologies, the advantages of this invention are as follows: by setting up a baffle assembly, the vortex problem in the dead corner area between the bottom of the fume hood and the wall can be solved, and the oil fumes in this area are guided to the fume inlet. The baffle assembly is positioned in front of the wall, providing protection and preventing the wall from being contaminated by splashed oil droplets or soup. Attached Figure Description

In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] See Figure 1 , Figure 8 and Figure 11 A range hood includes a smoke collection hood 1, with a smoke inlet 11 on the front side of the smoke collection hood 1.

[0032] The range hood also includes a baffle assembly 2 that can guide the fumes below the bottom of the fume collection hood 1 to the fume inlet 11.

[0033] The deflector assembly 2 can be in a first state hidden inside the fume hood 1 and a second state at least partially exposed at the bottom of the fume hood 1, so as to avoid the deflector assembly 2 still occupying the cooking space below the fume hood 1 when the range hood is turned off.

[0034] See Figures 2-7 and Figures 9-10 The range hood also includes a motion mechanism capable of driving the baffle assembly 2. The motion mechanism includes a drive unit 31, rollers 32, and a bracket 33. The drive unit 31 is located inside the smoke collection hood 1 and includes a rotating output shaft 311. The output shaft 311 is connected to the rotation center of the rollers 32, and the rollers 32 are driven to rotate by the output shaft 311. The bracket 33 is rotatably mounted on the output shaft 311. The baffle assembly 2 includes a baffle body 21, which is positioned between the bracket 33 and the rollers 32. The rollers 32 abut against the baffle body 21, and the baffle body 21 is driven to move by the rollers 32. The surface of the baffle body 21 that contacts the rollers 32 can be made of a frosted material or a rack, making the rollers 32 the active end driving the baffle body 21. The inner side of the smoke hood 1 is provided with a guide groove 12 that can guide and limit the flow guide plate body 21. The guide groove 12 is longitudinally arranged on the left and right sides of the flow guide plate body 21.

[0035] See Figure 7 , Figure 10 and Figure 13 The bracket 33 includes a connecting part 331 and a snap-fit ​​part 332. One end of the connecting part 331 is rotatably connected to the output shaft 311, and the other end of the connecting part 331 is connected to the snap-fit ​​part 332. The snap-fit ​​part 332 is located on the side of the guide plate body 21 away from the roller 32, and the guide plate body 21 is confined between the roller 32 and the snap-fit ​​part 332.

[0036] See Figures 11-13 The deflector assembly 2 also includes an anti-detachment part 22 that prevents the deflector body 21 from disengaging from the roller 32 and the locking part 332 when it moves downward. The anti-detachment part 22 is located on the top of the deflector body 21 and can engage with the locking part 332. After the anti-detachment part 22 engages with the locking part 332, the roller 32 can drive the deflector body 21 to tilt forward.

[0037] See Figures 4-7 , Figures 9-10 and Figures 12-13 There are two motion mechanisms, which are symmetrically arranged on the left and right sides of the main body 21 of the guide plate.

[0038] See Figure 6 , Figure 9 and Figure 12 The main body 21 of the air deflector is provided with noise reduction holes 211, and the back side of the main body 21 of the air deflector is provided with sound-absorbing cotton 4.

[0039] See Figure 1 , Figure 8 and Figure 11 By setting a baffle assembly 2 at the lower part of the fume hood 1, when not in operation, the baffle assembly 2 is embedded in the guide groove 12 and hidden inside the fume hood 1. When in operation, the baffle assembly 2 unfolds vertically downward and close to the stovetop under the drive of the roller 32, guiding the oil fumes located below the fume hood 1 to the smoke inlet 11. However, for better airflow and noise reduction, the anti-detachment part 22 of the baffle assembly 2 is engaged with the locking part 332 of the bracket 33. At this time, the roller 32 continues to rotate, forcing the baffle assembly 2 to drive the bracket 33 to rotate around the output shaft 311, so that the baffle assembly 2 tilts forward and forms a certain angle with the stovetop. The oil fumes can flow along this structure to the vicinity of the smoke inlet 11, improving the smoke extraction efficiency of the range hood.

[0040] When stir-frying or other Chinese cooking methods, walls are easily splattered with oil droplets or soup, and these surfaces are difficult to clean. The deflector assembly 2, when in operation, shields the wall from these splashes, providing protection and preventing contamination. The deflector surface of the deflector assembly 2 can be made of a smooth, non-stick material or have an oleophobic coating, making it easy to clean.

[0041] See Figures 11-12 When the main body 21 of the baffle plate is tilted towards the front, the noise reduction holes 211 and sound-absorbing cotton 4 on the main body 21 of the baffle plate can not only absorb the noise coming out of the smoke inlet 11, but also absorb the noise reflected by the stove, and the noise reduction effect is obvious.

[0042] The aforementioned baffle assembly can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the drive mechanism of the baffle assembly to perform corresponding operations, thereby realizing intelligent control of the range hood and improving the user experience.
