[0049] Range hoods have become one of the essential appliances in modern family kitchens. As the application rate of range hoods increases, people pay more and more attention to the range hood's oil fume extraction effect and installation aesthetics. At present, for the sake of aesthetics, the area of ​​the oil fume outlet of the lifting range hood is fixed, which may cause oil fume to escape.

[0050] Moreover, most of the lift-type range hoods are now lowered to the bottom, and the height of the range hood cannot be adjusted according to the actual situation of the smoke. This will affect some users whose kitchens are lower, and it makes them have to adjust the overall decoration of the kitchen in order to install the range hood, which is not only unsightly, but also time-consuming and laborious.

[0051] For the convenience of subsequent description, the first direction in the present invention refers to Figure 1 The direction indicated by X and the direction opposite to it are both the first direction, that is, the direction parallel to the range hood, and the second direction is the direction indicated by Y in the figure, that is, Figure 1 The direction indicated by Y is Figure 1 In the direction of left and right.

[0052] In view of this, the present invention provides a range hood 100, which can increase the adsorbable area of ​​the range hood 100.

[0053] See also Figure 1 The present invention provides a range hood 100, comprising: a range hood frame 10, a smoke collecting hood 20, a smoke collecting assembly 30, and a driving mechanism 40;

[0054] The smoke machine frame 10 is arranged outside the smoke collecting hood 20, the smoke collecting assembly 30 is movably arranged on both sides of the smoke collecting hood 20, the driving mechanism 40 is arranged on the smoke machine frame 10, the driving mechanism 40 is connected with the smoke collecting assembly 30 and the smoke collecting hood 20, and the driving mechanism 40 is used to drive the smoke collecting hood 20 to move along the first direction and drive the smoke collecting assembly 30 to switch between an open state or a closed state;

[0055] When the smoke collecting assembly 30 is in an open state, the smoke collecting assembly 30 is located outside the smoke collecting hood 20 , and when the smoke collecting assembly 30 is in a closed state, the smoke collecting assembly 30 is located inside the smoke collecting hood 20 .

[0056] The range hood 100 is provided with a smoke collecting hood 20 on the range hood frame 10, and the smoke collecting hood 20 has a flue therein, through which the smoke in the kitchen is discharged, and a driving assembly is provided on the range hood frame 10, and the smoke collecting hood 20 is driven to move along the length direction of the range hood frame 10 by a driving mechanism 40, and smoke collecting assemblies 30 are provided on both sides of the smoke collecting hood 20, and the smoke collecting assemblies 30 are also connected to the driving mechanism 40, and the driving mechanism 40 can drive the smoke collecting assemblies 30 to open or close. When the driving mechanism 40 drives the smoke collecting assemblies 30 to open, the smoke collecting assemblies 30 arranged on both sides of the smoke collecting hood extend out of the smoke collecting hood, and the smoke collecting assemblies 30 are connected to the flue inside the smoke collecting hood, so that the smoke collecting assemblies 30 can absorb the smoke in the kitchen, thereby increasing the adsorption area of ​​the range hood 100. When the driving mechanism 40 drives the smoke collecting assemblies 30 to close, the smoke collecting assemblies 30 are located in the smoke collecting hood 20, so that the space occupied by the range hood 100 in the kitchen when not in use can be reduced.

[0057] It can be understood that the hood frame 10 is fixedly arranged on the wall of the kitchen, and a smoke hood 20 is sleeved on the outside of the hood frame 10. A driving mechanism 40 is arranged on the hood frame 10, and the driving mechanism 40 is used to drive the smoke hood 20 so that the smoke hood 20 can move along the first direction, that is, move up and down in the length direction of the hood frame 10; in the working state (when in use), the driving mechanism 40 drives the smoke hood 20 to move along the first direction, so that the range hood 100 is located in the working position, even if the smoke hood 20 is close to the stove, so that the smoke hood 20 can better discharge the oil smoke in the kitchen through the range hood 100; in the non-working state (when the use is finished), the driving mechanism 40 drives the smoke hood 20 to move along the direction of the first direction, even if the smoke hood 20 is far away from the stove, so that the use space of the stove can be increased. At the same time, it can also reduce the space occupied by the range hood 100 in the kitchen and improve the space utilization rate in the kitchen.

[0058] It can be understood that the smoke collecting assembly 30 is arranged on the left and right sides of the smoke hood 20, and the driving mechanism 40 is connected to the smoke collecting assembly 30, and the driving mechanism 40 is connected to the smoke collecting assembly 30 to drive the smoke collecting assembly 30 to open or close; when work is required, the smoke hood 20 is in the above-mentioned working state, and at the same time the smoke collecting assembly 30 is turned on to work with the smoke hood 20 to discharge the fumes in the kitchen, which can increase the smoking area of ​​the range hood 100 and reduce the escape of fumes.

[0059] In some embodiments, the smoke collecting hood 20 has a first side wall and a second side wall that are oppositely disposed; and the smoke collecting assembly 30 is disposed on the first side wall or the second side wall.

[0060] It can be understood that the smoke hood 20 has a first side wall and a second side wall opposite to each other, wherein a smoke collecting assembly 30 is arranged on the first side wall or the second side wall. By arranging the smoke collecting assembly 30 on one side of the smoke hood 20, the smoke can be discharged from the range hood 100 through the smoke collecting assembly 30 to realize the smoke collecting function of the range hood 100.

[0061] In some embodiments, the smoke collecting assembly 30 includes a first smoke collecting member 31 and a second smoke collecting member 32;

[0062] The smoke collecting hood 20 has a first side wall and a second side wall which are arranged opposite to each other. The first side wall is provided with a first installation opening 21, and the second side wall is provided with a second installation opening 22. The first smoke collecting opening 21 and the second installation opening 22 are both provided with hinges 50.

[0063] The first smoke collecting member 31 is arranged at the first smoke collecting opening 21 through a hinge 50 , and the second smoke collecting member 32 is arranged at the second installation opening 22 .

[0064] It can be understood that the smoke hood 20 has a first side wall and a second side wall opposite to each other, and a smoke collecting assembly 30 is arranged on the first side wall and the second side wall. The smoke collecting assembly 30 extracts the smoke through the first smoke collecting piece 31 and the second smoke collecting piece 32 on both sides of the smoke hood 20, so as to better discharge the smoke in the kitchen through the range hood 100.

[0065] Specifically, the smoke collecting component 30 includes a first smoke collecting component 31 and a second smoke collecting component 32. To facilitate the installation of the first smoke collecting component 31 and the second smoke collecting component 32, a first mounting port 21 and a second mounting port 22 are provided on the first side wall, and a hinge 50 is provided at the first mounting port 21 and the second mounting port 22. The first smoke collecting component 31 is connected by the hinge 50, so that the first smoke collecting component 31 can rotate in the first mounting port 21 to open or close the first mounting port 21; similarly, the second smoke collecting component 32 is connected by the hinge 50, so that the second smoke collecting component 32 can rotate in the second mounting port 22 to open or close the second mounting port 22; in this way, the range hood 100 can be turned on or off.

[0066] See also Figure 2 and Figure 3 The first smoke collecting member 31 and the second smoke collecting member 32 each include: a first guide plate 33, a second guide plate 34, a third guide plate 35 and a fourth guide plate 36;

[0067] The first guide plate 33 and the third guide plate 35 are arranged on both sides of the second guide plate 34, and both sides of the fourth guide plate 36 are respectively connected to the first guide plate 33 and the third guide plate; wherein a flue is formed between the fourth guide plate 36 and the first guide plate 33, the second guide plate 34, and the third guide plate 35.

[0068] It can be understood that the first smoke collecting piece 31 and the second smoke collecting piece 32 both include: a first guide plate 33, a second guide plate 34, a third guide plate 35, and a fourth guide plate 36, wherein the first guide plate 33 and the third guide plate 35 are both arranged on both sides of the second guide plate 34, so that the first guide plate 33, the second guide plate 34, and the third guide plate 35 form a guide groove, wherein the first guide plate 33 and the third guide plate 35 are both movably connected to the smoke hood 20, so that the first smoke collecting piece 31 can be opened or closed, and after the first smoke collecting piece 31 is installed on the smoke hood, the first guide plate 33, the second guide plate 34 and the third guide plate 35 form a flue with the smoke hood, and the oil smoke enters the smoke hood 20 through the flue to collect the oil smoke.

[0069] It can be understood that a fourth guide plate 36 is provided on the smoke guide groove formed by the first guide plate 33, the second guide plate 34, and the third guide plate 35, and the fourth guide plate 36 is connected to the first guide plate 33, the second guide plate 34, and the third guide plate 35, and there is a gap between the fourth guide plate 36 and the first guide plate 33, the second guide plate 34, and the third guide plate 35, that is, a flue is formed between the fourth guide plate 36 and the first guide plate 33, the second guide plate 34, and the third guide plate 35, and the oil smoke can enter the smoke hood 20 through the gap between the fourth guide plate 36 and the first guide plate 33, the second guide plate 34, and the third guide plate 35, thereby realizing the collection of oil smoke.

[0070] See also Figure 8 and Fig. 9 In some embodiments, the smoke collecting hood 20 has a bottom plate 23, and an air inlet 24 is provided on the bottom plate 23;

[0071] When the smoke collecting assembly 30 is in a closed state, the fourth guide plate 36 forms a first angle α with the bottom plate 23 ; when the smoke collecting assembly 30 is in an open state, the smoke collecting assembly 30 forms a second angle β with the bottom plate 23 .

[0072] See also Figure 8 It can be understood that a bottom plate 23 is provided at the bottom of the smoke hood 20, and an air inlet 24 is provided on the bottom plate 23. The air inlet 24 is the smoke inlet. The oil smoke enters the smoke hood 20 through the air inlet 24, and then the oil smoke is discharged through the smoke hood 20, thereby realizing the collection of the oil smoke. When the smoke collecting assembly 30 is closed, the fourth guide plates 36 on the first smoke collecting member 31 and the second smoke collecting member 32 form a first angle α with the bottom plate 23. When the smoke collecting assembly 30 is closed, the first smoke collecting member 31 and the second smoke collecting member 32 are located in the smoke collecting hood 20. At this time, the fourth guide plates 36 in the first smoke collecting member 31 and the fourth guide plates 36 in the second smoke collecting member 32 are both located above the bottom plate 23, and the fourth guide plates 36 in the first smoke collecting member 31 and the fourth guide plates 36 in the second smoke collecting member 32 form a first angle α, wherein the first angle α is 20° to 50°, and can specifically be other angles such as 20°, 25°, 30°, 35°, 40°, 45°, 50°, etc.;

[0073] The above-mentioned first angle α will affect the size of the oil fume suction force corresponding to the bottom plate 23; specifically, when the smoke collecting component 30 is closed, the larger the angle of the first angle α, the smaller the distance between the two relative guide plates, so that the airflow rate can be relatively accelerated, and the negative pressure caused by the range hood 100 is relatively large; its usage scenario is when the amount of oil fume is small. Specifically, when the amount of oil fume is small, a larger smoking area is not required, but a larger negative pressure is required. The first angle α formed by the fourth guide plate 36 in the first smoke collecting component 31 and the fourth guide plate 36 in the second smoke collecting component 32 can enable the range hood 100 to suck as much oil fume into the range hood 100 as possible when the amount of oil fume is small, thereby reducing the occurrence of oil fume escape.

[0074] When the smoke collecting component 30 is closed, the smaller the first angle α is, the larger the distance between the two relative guide plates is, so that the airflow velocity is relatively small, and the negative pressure space caused by the range hood 100 is relatively large. Its usage scenario is when the amount of oil smoke is large. Specifically, when the amount of oil smoke is large, a larger smoke intake area is required to discharge the oil smoke. Therefore, the larger gap between the fourth guide plate 36 in the first smoke collecting component 31 and the fourth guide plate 36 in the second smoke collecting component 32 can make the oil smoke be discharged from the flue more quickly, so as to improve the smoke exhaust efficiency of the range hood 100.

[0075] See also Fig. 9 When the smoke collecting assembly 30 is unfolded, the fourth guide plate 36 on the first smoke collecting piece 31 and the second smoke collecting piece 32 forms a second angle β with the bottom plate 23, wherein the second angle β is 100° to 160°, and specifically can be 100°, 105°, 110°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160° or other angles.

[0076] The second angle β also affects the smoke collecting area of ​​the smoke collecting assembly 30. Specifically, when the second angle β is small, the first smoke collecting member 31 and the second smoke collecting member 32 are more fully deployed, so that the smoke collecting area of ​​the smoke collecting assembly 30 is larger, which can effectively reduce the escape of oil smoke. When the second angle β is large, the first smoke collecting member 31 and the second smoke collecting member 32 are relatively incompletely deployed, and the smoke collecting area is relatively small. Specifically, when the smoke collecting assembly 30 is turned on, the first smoke collecting piece 31 and the second smoke collecting piece 32 are located on both sides of the smoke hood 20. At this time, the fourth guide plate 36 is no longer located above the bottom plate 23, and the flue corresponding to the bottom plate 23 is completely opened. Most of the oil smoke can be discharged through the smoke hood 20. The first smoke collecting piece 31 and the second smoke collecting piece 32 on both sides of the smoke hood 20 can absorb the smoke diffused from the smoke hood 20. In this way, the smoking area of ​​the range hood 100 can be increased to reduce the occurrence of oil smoke escape and improve the smoke exhaust efficiency of the range hood 100.

[0077] See also Figures 4 to 6 In some embodiments, the driving mechanism 40 includes: a driving member 41, a first rack 42, and a second rack 43;

[0078] The driving member 41 is disposed on the smoke machine frame 10, the first rack 42 is connected to the smoke collecting cover 20, the second rack is connected to the first smoke collecting member 31 or the second smoke collecting member 32, and the first rack 42 and the second rack 43 are both meshed with the driving member 41;

[0079] The meshing length between the first rack 42 and the driving member 41 is greater than the meshing length between the second rack 43 and the driving member 41 .

[0080] It can be understood that the above-mentioned driving mechanism 40 can be provided in two sets, which are respectively arranged on two opposite sides of the range hood frame 10. The following content will be described by taking the arrangement on one side as an example.

[0081] Specifically, the driving mechanism 40 includes a driving member 41, a first rack 42, and a second rack 43, wherein the driving member 41 is fixedly arranged on the smoke machine frame 10, the first rack 42 is connected to the smoke hood 20, the second rack 43 is connected to the first smoke collecting member 31, and the first rack 42 and the second rack 43 are both engaged with the driving member 41. When the driving member 41 rotates, it drives the first rack 42 and the second rack 43 to move, thereby driving the smoke hood 20 to move along the first direction, and driving the driving member 41 to expand.

[0082] The meshing length between the first rack 42 and the driving member 41 is greater than the meshing length between the second rack 43 and the driving member 41. This is to enable the range hood 100 to descend when the amount of oil smoke is small, and after descending to the preset position, the range hood 100 works to absorb oil smoke without the first smoke collecting member 31 and the second smoke collecting member 32 being unfolded.

[0083] It can be understood that a driving gear is disposed on the rotating shaft of the driving member 41 . When the rotating shaft rotates, the driving gear is driven to rotate, thereby driving the first rack 42 and the second rack 43 to rotate.

[0084] See also Figure 3 , in some embodiments, further comprising: a guide member 60;

[0085] The second rack 43 is connected to the guide member 60 at one side close to the smoke collecting assembly 30, and the other end of the guide member 60 is connected to the first smoke collecting member 31 or the second smoke collecting member 32 to drive the smoke collecting assembly 30 to be in an open state or a closed state;

[0086] The second rack 43 includes a main body 431 and a guide portion 432, and the guide portion 432 and the main body 431 form an angle;

[0087] The guide portion 432 has a groove 633 . The end of the guide member 60 away from the smoke collecting assembly 30 is provided with a protrusion 61 , and the protrusion 61 cooperates with the groove 633 .

[0088] It can be understood that the present embodiment is explained by taking the unfolding of the first smoke collecting piece 31 as an example. Specifically, the above-mentioned guide member 60 is used to enable the second rack 43 to drive the first smoke collecting piece 31 to be movable and unfolded. The guide member 60 is arranged in an arc shape, one end of which is slidably connected to the second rack 43, and the other end of which is connected to the first smoke collecting piece 31. When the driving member 41 drives the second rack 43 to rotate, the second rack 43 moves in the first direction, so that the second rack 43 drives the guide member 60 to move, and then drives the first smoke collecting piece 31 to unfold; when the first smoke collecting piece 31 is closed, the second rack 43 moves in the direction away from the first smoke collecting piece 31, and the second rack 43 drives the guide member 60 to move, so that the first smoke collecting piece 31 is in a closed state.

[0089] It can be understood that the second rack 43 has a main body 431 and a guide portion 432, and the main body 431 forms an angle with the guide portion 432, wherein the main body 431 is the part that can be driven by the driving member 41, and the guide portion 432 is used to cooperate with the guide member 60; specifically, a groove 633 is provided on the guide portion 432, and a protrusion 61 is provided on the side of the guide member 60 away from the smoke collecting member, and the protrusion 61 is inserted into the groove 633, so that when the driving member 41 drives the main body 431 to move, the second rack 43 moves in a direction close to the first smoke collecting member 31, and the guide portion 432 also moves in a direction close to the first smoke collecting member 31, so that the guide member 60 is pushed to move toward the part away from the first rack 42, thereby driving the first smoke collecting member 31 to open. When the second rack 43 moves in the opposite direction away from the first smoke collecting member 31, the guide portion 432 moves away from the first smoke collecting member 31, so that the guide member 60 is pulled to move toward the portion close to the first rack 42, thereby driving the first smoke collecting member 31 to close.

[0090] See also Figure 4 , in some embodiments, further comprising: a protective shell 91;

[0091] The protective shell 91 is disposed on the range hood frame 10 , and a receiving cavity 92 is defined in the protective shell 91 . Both the first rack 42 and the second rack 43 are located in the receiving cavity 92 .

[0092] It can be understood that in order to protect the driving mechanism 40, a protective shell 91 is provided at the part where the driving member 41 is meshed with the first rack 42 and the second rack 43. The protective shell 91 can be fixedly set on the smoke machine frame 10 to protect the part where the driving member 41 is meshed with the first rack 42 and the second rack 43.

[0093] See also Figure 6 and Figure 7 , in some embodiments, further comprising: a slide rail;

[0094] A first guide rail mechanism 70 and a second guide rail mechanism 80; the first guide rail mechanism 70 includes a first slide rail 71 and a first slider 72, and the second guide rail mechanism 80 includes a second slide rail 81 and a second slider 82;

[0095] The first slider 72 and the second slider 82 are both arranged on the side of the protective shell 91 away from the driving member 41, the first slide rail 71 is connected to the first rack 42, the first rack 42 is connected to the smoke hood 20, the second slide rail 81 is connected to the second rack 43, a first limiting member 73 is arranged on the side of the second slide rail 81 away from the bottom plate 23, a second limiting member 83 is arranged on the first slide rail 71, the height of the first limiting member 73 along the first direction is higher than the second limiting member 83, when the second limiting member 83 conflicts with the first limiting member 73, the second rack 43 drives the first rack 42 to move.

[0096] It can be understood that the first guide rail mechanism 70 includes a first slide rail 71 and a first slider 72, and the second guide rail mechanism 80 includes a second slide rail 81 and a second slider 82, wherein the first slider 72 and the second slider 82 are both fixedly arranged on both sides of the protective shell 91, so that the first slider 72 is fixed on the protective shell 91, and at this time, the first rack 42 can drive the first slide rail 71 to move, and the first slide rail 71 is also connected to the smoke hood 20, when the first rack 42 moves, it can drive the first slide rail 71 to move, and then drive the smoke hood 20 to move along the first direction, because the part of the first rack 42 with teeth is shorter, therefore, when the first rack 42 reaches the preset position, the first rack 42 is no longer engaged with the driving member 41, and the smoke hood 20 will not move at this time.

[0097] A first limit member 73 is provided on the side of the slide rail away from the bottom plate 23, that is, a limit member is provided on the top of the slide rail, and a second limit member 83 is provided on the first rack 42. The height of the first limit member 73 in the first direction is higher than the height of the second limit member 83 in the first direction.

[0098] Since the meshing length between the second rack 43 and the driving member 41 is smaller than the meshing length between the first rack 42 and the driving member 41, when the first rack 42 rotates to the part without teeth and stops rotating, when it is necessary to drive the first rack 42 to rotate in the reverse direction, the first rack 42 cannot mesh with the driving member 41. However, the second rack 43 can mesh with the driving member 41, and when the second rack 43 moves, it drives the first slide rail 71 to move. The first stopper 73 disposed on the first slide rail 71 abuts against the second stopper 83 during the upward movement, and drives the second stopper 83 to move upward, so that the first rack 42 can be driven to move and mesh with the driving member 41, so as to drive the smoke hood 20 to move upward.

[0099] See also Fig. 9 In some embodiments, it further includes an oil collecting tank 90;

[0100] The oil collecting tank 90 is detachably disposed on one side of the bottom plate 23 . The oil collecting tank 90 is communicated with the interior of the smoke collecting hood 20 to collect the oil smoke inside the smoke collecting hood 20 .

[0101] It can be understood that the oil collecting tank 90 is detachably arranged on the side of the bottom plate 23 close to the wall, and the oil collecting tank 90 is connected to the interior of the smoke hood 20. When the oil smoke inside the smoke hood 20 is cooled, the oil stains generated can be discharged into the oil collecting tank 90 to collect the oil smoke in the smoke hood 20 for easy treatment of the oil smoke.
