Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0043] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] Range hoods have become an indispensable appliance in modern family kitchens. As their usage rate increases, people are paying more and more attention to their smoke extraction efficiency and aesthetic appeal. Currently, for the sake of aesthetics, lift-type range hoods have fixed smoke vents. However, the suction area of ​​these fixed vents is determined at the factory. Therefore, in cases with larger stovetops, smoke may escape.

[0045] Furthermore, the drive mechanism in current lifting range hoods is an integral lifting type. The normal operation of the range hood requires it to be lowered to a preset position before it can start working. This means that if the drive mechanism in the range hood malfunctions, the range hood cannot be turned on, which seriously affects its normal use.

[0046] For ease of subsequent explanation, this invention uses... Figure 11 The viewpoint shown defines a first direction and a second direction, where the first direction is as follows: Figure 11 The X direction shown is as follows: Figure 11 The left and right directions are shown, and the second direction is as follows: Figure 11 The Y direction shown is as follows: Figure 11 The front and back directions are shown.

[0047] Therefore, this embodiment provides a range hood 100. The range hood 100 can increase the smoke collection area and reduce the escape of oil fumes.

[0048] Please see Figure 1 A range hood 100 includes: a smoke collection hood 10, a smoke collection assembly 20, and a drive mechanism 30;

[0049] The drive mechanism 30 is disposed on the smoke collection assembly 20, and the smoke collection assembly 20 is disposed on the side of the smoke hood 10 away from the drive mechanism 30. The drive mechanism 30 is movably connected to the smoke collection assembly 20, and the drive mechanism 30 is used to drive the smoke collection assembly 20 to open or close.

[0050] When the smoke collection assembly 20 is deployed, it is located outside the smoke collection hood 10; when the smoke collection assembly 20 is closed, it is located inside the smoke collection hood 10.

[0051] The range hood 100 described above is equipped with a smoke collection component 20 on the smoke collection hood 10. The smoke collection component 20 is connected to the drive mechanism 30. The drive mechanism 30 can drive the smoke collection component 20 to unfold. After unfolding, the angle of the smoke collection component 20 changes, and the smoke absorption area increases. This can improve the smoke absorption area of ​​the range hood 100, thereby reducing the escape of oil fumes. After the range hood 100 is used, the drive mechanism 30 drives the smoke collection component 20 to close. The smoke collection component 20 is located inside the smoke collection hood 10, thereby saving kitchen space. Therefore, the range hood 100 of the present invention can reduce the space occupied in the kitchen when not in use, and also has a large smoke absorption area, so that most of the oil fumes can be discharged by the range hood 100, thereby reducing the escape of oil fumes and improving the smoke absorption efficiency of the range hood 100.

[0052] Please see Figure 1 In some embodiments, the smoke collection assembly 20 includes a first smoke collection element 21 and a second smoke collection element 22, which are spaced apart along one direction on two opposite side walls of the smoke hood 10.

[0053] Understandably, the first smoke collecting element 21 and the second smoke collecting element 22 are spaced apart along one direction on two opposite side walls of the smoke hood 10, that is, the first smoke collecting element 21 is movably mounted as shown in the image. Figure 1 As shown on the left, the second smoke collection unit 22 is movably set as follows: Figure 1 As shown on the right, the first smoke collector 21 and the second smoke collector 22 can both be driven to open or close by the drive mechanism 30. When the first smoke collector 21 and the second smoke collector 22 are closed, both the first smoke collector 21 and the second smoke collector 22 are located inside the smoke hood 10.

[0054] When the first smoke collector 21 and the second smoke collector 22 are open, their states are as follows: Figure 1 As shown, the first smoke collector 21 extends to the left side of the smoke hood 10, and the second smoke collector 22 extends to the right side of the smoke hood 10. This expansion increases the smoke extraction range of the range hood 100, thereby reducing smoke escape and improving its smoke extraction efficiency. Both the first and second smoke collectors 21 and 22 are connected to the smoke hood 10; therefore, the smoke entering the first and second smoke collectors 21 and 22 is drawn into the smoke hood 10 and then discharged through it.

[0055] Please see Figure 2 and Figure 3 In some embodiments, the smoke hood 10 is provided with a first mounting port 11 and a second mounting port 12 at intervals along a first direction, and the first mounting port 11 and the second mounting port 12 are located on the side of the smoke hood 10 away from the drive mechanism 30.

[0056] The first smoke collector 21 is movably disposed within the first mounting port 11, and the second smoke collector 22 is movably disposed within the second mounting port 12.

[0057] Understandably, the smoke hood 10 includes a first plate, a second plate, a third plate, a fourth plate, and a top plate; wherein the first plate and the second plate are spaced apart along a first direction, the third plate and the fourth plate are spaced apart along a second direction, and the first plate, the second plate, the third plate, and the fourth plate are located around the top plate.

[0058] In order to install the first smoke collection component 21 and the second smoke collection component 22, in the smoke collection hood 10 as follows Figure 2 The left side shown is provided with a first mounting port 11, and the smoke hood 10 is as follows: Figure 2 The right side is provided with a second mounting port 12. The lengths of the first and second plates are shorter than the third or fourth plates. The bottom of the smoke hood 10 does not have a baffle 70. Thus, the left side and bottom of the smoke hood 10 form the first mounting port 11, and the right side and bottom of the smoke hood 10 form the second mounting port 12. The first smoke collecting element 21 is movably installed in the first mounting port 11, and the second smoke collecting element 22 is movably installed in the second mounting port 12. Thus, the first smoke collecting element 21 can be driven by the drive mechanism 30 to rotate within the first mounting port 11, thereby opening or closing the first smoke collecting element 21; similarly, the second smoke collecting element 22 can be driven by the drive mechanism 30 to rotate within the second mounting port 12, thereby opening or closing the second smoke collecting element 22.

[0059] Please see Figure 4 In some embodiments, the drive mechanism 30 includes: a first drive component 31 and a second drive component 32;

[0060] The first driving component 31 and the second driving component 32 are spaced apart along the second direction, and the first driving component 31 or the second driving component 32 is connected to the first smoke collecting component 21 and the second smoke collecting component 22.

[0061] The first driving component 31 or the second driving component 32 is used to drive the first smoke collecting component 21 and the second smoke collecting component 22 to open or close.

[0062] Understandably, the drive mechanism 30 includes a first drive component 31 and a second drive component 32. The first drive component 31 and the second drive component 32 are spaced apart on the smoke hood 10 along a second direction. The first drive component 31 can drive the first smoke collector 21 and the second smoke collector 22, and the second drive component 32 can also drive the first smoke collector 21 and the second smoke collector 22. The first drive component 31 and the second drive component 32 are provided to make the first smoke collector 21 and the second smoke collector 22 move more smoothly. The first drive component 31 and the second drive component 32 need to work synchronously or stop working synchronously to open or close the first smoke collector 21 or the second smoke collector 22.

[0063] Please see Figure 5 In some embodiments, both the first smoke collecting member 21 and the second smoke collecting member 22 include: a first connecting plate 23, a second connecting plate 24, a third connecting plate 25, and a fourth connecting plate 26;

[0064] The first connecting plate 23 and the second connecting plate 24 are spaced apart along the second direction, and the third connecting plate 25 and the fourth connecting plate 26 are sandwiched between the first connecting plate 23 and the second connecting plate 24; an included angle is provided between the third connecting plate 25 and the fourth connecting plate 26; an opening 261 is provided on the fourth connecting plate 26, and the opening 261 communicates with the interior of the smoke hood 10.

[0065] Understandably, the first smoke collecting component 21 and the second smoke collecting component 22 have the same structure. The first smoke collecting component 21 includes a first connecting plate 23, a second connecting plate 24, a third connecting plate 25, and a fourth connecting plate 26. The first connecting plate 23 and the second connecting plate 24 are both configured as follows: Figure 5 The triangle shown, the first connecting plate 23 and the second connecting plate 24 are along the triangle as shown. Figure 5 or Figure 6 The front and rear directions are arranged sequentially, with the third connecting plate 25 and the fourth connecting plate 26 arranged along the same direction. Figure 5 or Figure 6 The third connecting plate 25 and the fourth connecting plate 26 are arranged vertically, sandwiched between the first connecting plate 23 and the second connecting plate 24, and an included angle α is provided between the third connecting plate 25 and the fourth connecting plate 26 (e.g., ...). Figure 7 As shown in the figure, the third connecting plate 25 and the fourth connecting plate 26 both form an angle with the horizontal direction of the range hood 100. An opening 261 is provided on the fourth connecting plate 26. The opening 261 is the smoke inlet of the first smoke collecting component 21 or the second smoke collecting component 22. The oil fumes enter the smoke collection hood 10 through the opening 261 and are then discharged.

[0066] In the open state, the first smoke collecting component 21 is located outside the smoke hood 10. At this time, the fourth connecting plate 26 of the first smoke collecting component 21 forms an angle with the horizontal plane. Therefore, the opening 261 also forms an angle with the horizontal plane, and the direction of the angle is as follows: Figure 3 As shown on the left side; the second smoke collector 22 is located outside the smoke hood 10. At this time, the fourth connecting plate 26 in the second smoke collector 22 forms an angle with the horizontal plane. Therefore, the opening 261 also forms an angle with the horizontal plane, and the direction of the angle is as follows. Figure 3 As shown on the right side; the angle formed between the two openings 261 and the horizontal plane can expand the smoke extraction area on both sides of the range hood 100, thereby reducing the escape of oil fumes and improving the smoke extraction efficiency of the range hood 100.

[0067] like Figure 6 The image shows the first smoke collector 21 or the second smoke collector 22 in its closed state within the smoke hood 10. For example... Figure 7 The image shows the first smoke collector 21 or the second smoke collector 22 in the open state inside the smoke hood 10.

[0068] Please see Figure 9 In some implementations, it also includes: a crossbar 40;

[0069] The crossbar 40 is located between the first mounting port 11 and the second mounting port 12, and the two ends of the crossbar 40 are connected to the two opposite side walls of the smoke hood 10; the first smoke collecting component 21 and the second smoke collecting component 22 are movably connected to the crossbar 40.

[0070] Understandably, the crossbar 40 is positioned between the first mounting port 11 and the second mounting port 12, with one end of the crossbar 40 connected to the third plate and the other end connected to the fourth plate. In this way, the crossbar 40 can be fixed. The crossbar 40 is used to movably connect the first smoke collecting component 21 and the second smoke collecting component 22, providing support for the unfolding of the first smoke collecting component 21 and the second smoke collecting component 22.

[0071] Please see Figure 9 In some embodiments, it also includes: a first connector 50 and a second connector 60;

[0072] One end of the first connector 50 is hinged to the crossbar 40, and the other end of the first connector 50 is connected to the fourth connecting plate 26; one end of the second connector 60 is connected to the first drive assembly 31 or the second drive assembly 32, and the other end of the second connector 60 is connected to the third connecting plate 25.

[0073] Understandably, the first connecting member 50 is used to connect the crossbar 40 and the first smoke collector 21 or the second smoke collector 22, and the second connecting member 60 is used to connect the first driving mechanism 30 to the first smoke collector 21 or the second smoke collector 22, or the second driving mechanism to the first smoke collector 21 or the second smoke collector 22. Specifically, one end of the first connecting member 50 is rotatably connected to the crossbar 40, and the other end of the first connecting member 50 is rotatably connected to the fourth connecting plate 26.

[0074] One end of the second connector 60 is used to connect the first drive mechanism 30 and the second drive mechanism 30, and the other end of the second connector 60 is used to connect the third connecting plate 25. The end of the second connector 60 connected to the first drive mechanism 30 is fixedly connected, and the end of the second connector 60 connected to the third connecting plate 25 is movably connected.

[0075] The first smoke collector 21 is used as an example for explanation. The driving principle of the second smoke collector 22 is the same as that of the first smoke collector 21.

[0076] Specifically, when the first drive mechanism 30 rotates, it drives the second connecting member 60 to rotate. When the second connecting member 60 rotates, it pushes the first smoke collector 21 to move away from the second smoke collector 22. Since the first smoke collector 21 is triangular, and the second connecting member 60 pushes the first smoke collector 21 from back to front, the first smoke collector 21 will also move downwards. However, the first connecting member 50 is located below the first smoke collector 21 and is rotatably connected to it. Therefore, the first smoke collector 21... Under the influence of the thrust of the second connector 60 and the pull of the first connector 50, the opening 261 that was originally perpendicular to the horizontal plane becomes an opening 261 that is inclined to the horizontal plane (the opening 261 that was originally located on the side of the smoke hood 10 becomes a downward opening 261). In this way, the first smoke collecting component 21 and the second smoke collecting component 22 can enable the range hood 100 to have a larger smoke extraction range, reduce the occurrence of smoke escape, and enable the range hood 100 to have a better smoke extraction effect, thereby improving the smoke extraction efficiency of the range hood 100.

[0077] Optionally, both the first connector 50 and the second connector 60 are configured to connect the two ends of the fourth connecting plate 26, and both the first connector 50 and the second connector 60 can be plate-shaped or frame-shaped.

[0078] Please see Figure 9 In some embodiments, it also includes: baffle 70 and pull rod 80;

[0079] The baffle 70 is movably mounted on the fourth connecting plate 26, one end of the pull rod 80 is movably mounted on the crossbar 40, and the other end of the pull rod 80 is movably connected to the baffle 70.

[0080] Understandably, the baffle 70 is movably mounted on the fourth connecting plate 26, covering the opening 261 of the fourth connecting plate 26. One side of the baffle 70 is movably mounted on the side of the opening 261 away from the crossbar 40. One end of the pull rod 80 is rotatably mounted on the crossbar 40, and the other end of the pull rod 80 is connected to the baffle 70. When the first smoke collector 21 is driven by the second connecting member 60 to move away from the crossbar 40, the baffle 70 is also driven to move away from the second smoke collector 22. Since the baffle 70 is movably mounted on the fourth connecting plate 26 and connected to the pull rod 80, when the first smoke collector 21 is driven to move away from the second smoke collector 22, the baffle 70 is restricted by the pull rod 80, causing the baffle 70 to rotate away from the opening 261, thereby opening the opening 261.

[0081] When the first smoke collection component 21 is closed, the baffle 70 covers the opening 261. This prevents debris from entering the smoke collection hood 10 and affecting the normal use of the range hood 100. At the same time, it also makes the range hood 100 a closed unit when closed, making the range hood 100 more aesthetically pleasing.

[0082] In some embodiments, the pull rod 80 may also be movably mounted on the fourth connecting plate 26, with one end movably connected to the baffle 70 and the other end movably connected to the fourth connecting plate 26. When the ambiguous smoke collector is driven to move away from the second smoke collector 22, the baffle 70 is rotated, thereby opening the opening 261.

[0083] Please see Figure 8 In some embodiments, both the first drive assembly 31 and the second drive assembly 32 include: a drive member 33, a first rack 34, a second rack 35, a first rotating member 36, and a second rotating member 37.

[0084] The driving component 33 is connected to the first rack 34 and the second rack 35, and the first rotating component 36 is disposed on the second rack 35 and the second rotating component 37 is disposed on the second rack 35.

[0085] It is understandable that the first drive component 31 and the second drive component 32 are the same drive mechanism 30. The following explanation will take the first drive component 31 as an example.

[0086] The first drive assembly 31 includes a drive member 33, a first rack 34, a second rack 35, a first rotating member 36, and a second rotating member 37. The drive member 33 is used to drive the first rack 34 to move away from the second rack 35 and to drive the second rack 35 to move away from the first rack 34. The first rotating member 36 is disposed on the first rack 34, and the second rotating member 37 is disposed on the second rack 35.

[0087] The first rack 34, the second rack 35, the first rotating member 36, the second rotating member 37, and the driving member 33 are all disposed on the side wall of the smoke hood 10 where the first mounting port 11 and the second mounting port 12 are not provided (i.e., on the third plate or the fourth plate). The first rotating member 36 and the second rotating member 37 are both rotatable.

[0088] Optionally, the aforementioned driving component 33 can be a telescopic rod, which has two telescopic arms that can extend and retract in opposite directions. The first rack 34 and the second rack 35 are respectively disposed on the two telescopic arms. When the two telescopic arms drive the first rack 34 and the second rack 35 to move, they drive the first rotating component 36 and the second rotating component 37 to rotate. The first rotating component 36 and the second rotating component 37 are both connected to the second connecting component 60. Therefore, when the first rotating component 36 and the second rotating component 37 rotate, the first driving mechanism 30 can drive the first smoke collecting component 21 and the second smoke collecting component 22 to rotate.

[0089] Optionally, the first driving assembly 31 may further include a first driving member 33, a second driving member 33, a first rotating member 36, and a second rotating member 37. The first driving member 33 is connected to the first rotating member 36, and the second driving member 33 is connected to the second rotating member 37. In this way, the first driving member 33 can drive the first rotating member 36 to rotate, and the second driving member 33 can drive the second rotating member 37 to rotate, so as to drive the first smoke collecting member 21 and the second smoke collecting member 22.

[0090] Please see Figure 10 In some embodiments, it also includes: a smoke machine frame 90 and a lifting mechanism 91;

[0091] The smoke collection hood 10 is sleeved on the smoke machine frame 90, and the lifting mechanism 91 is disposed on the smoke machine frame 90. The lifting mechanism 91 is connected to the smoke collection hood 10 and is used to drive the smoke collection hood 10 to rise and fall.

[0092] Understandably, the range hood 100 also includes a range hood frame 90, with a smoke collection hood 10 fitted around the outer perimeter of the range hood frame 90. A lifting mechanism 91 is installed on the range hood frame 90, connected to the smoke collection hood 10. The lifting mechanism 91 can drive the smoke collection hood 10 to move on the range hood frame 90. The lifting mechanism 91 allows the smoke collection hood 10 to be closer to the stovetop. When the smoke collection hood 10 is closer to the stovetop, the first smoke collecting element 21 and the second smoke collecting element 22 can be placed closer to the stovetop, thus improving the overall smoke extraction efficiency of the range hood 100.

[0093] Optionally, the lifting mechanism 91 can be a lead screw mechanism or a telescopic rod mechanism.
