One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

Referring to fig. 1 to 4, the range hood includes a housing 10, an air guiding duct 20, a driving device 30, and a hood assembly 50, wherein a fan is disposed in the housing 10, and an air inlet (not shown) is disposed at the bottom of the housing 10. One end of the air duct 20 is connected to the air inlet, and the other end of the air duct 20 is connected to the smoke-collecting hood assembly 50, so that the smoke-collecting hood assembly 50 is connected to the lower side of the chassis 10 through the air duct 20, the air duct 20 is flexible, that is, the air duct 20 is a flexible duct, can be freely stretched and bent, and has a cross section of any shape, preferably, the air duct 20 is made of nylon cloth or other materials. The smoke-collecting hood assembly 50 is also hinged with a swing arm 40, and the driving device 30 is connected with the swing arm 40 to enable the smoke-collecting hood assembly 50 to swing, so that the main function of the driving device 30 is to drive the smoke-collecting hood assembly 50 to swing.

Foretell range hood, because it is connected with drive arrangement 30 through swing arm 40 to hold together petticoat pipe subassembly 50, and combine guide duct 20 to set up for the flexbile duct, when drive arrangement 30 drive swing arm 40, can make and hold together petticoat pipe subassembly 50 swing, thereby can swing according to the in service behavior of cooking utensils and hold together petticoat pipe subassembly 50, it is nearest with cooking utensils distance to make to hold together petticoat pipe subassembly 50, need not to increase fan rotational speed or increase impeller diameter, can reach better smoking effect, moreover, the steam generator is simple in structure, low cost, it is stable durable and the noise is little, user experience has been promoted.

As an exemplary embodiment, the swing arm 40 is a telescopic rod whose length can be adjusted. As shown in fig. 5, the air duct 20 has a telescopic mechanism 60 therein, and the telescopic mechanism 60 may be an electric telescopic mechanism including a telescopic driving member, and the telescopic driving member may be a motor. So, hold together petticoat pipe subassembly 50 not only can swing, still can go up and down the extension, can swing according to the in service behavior of cooking utensils and hold together petticoat pipe subassembly 50 adjustment and hold together left and right position of petticoat pipe subassembly on the one hand, do and hold together petticoat pipe subassembly 50 height according to pan height adjustment, make air inlet position and cooking utensils distance nearest to reach better smoking effect.

Referring to fig. 1 and 2 in combination, the swing arm 40 has a telescoping end 41 and a connecting end 42, the smoke cage assembly 50 is hinged to the telescoping end 41, and the connecting end 42 is connected to the drive device 30. In this way, by connecting the driving device 30 to the connecting end 42 of the swing arm 40 and connecting the smoke collecting hood assembly 50 to the telescopic end 41 of the swing arm 40, the need of the smoke collecting hood assembly 50 to swing can be satisfied, and the swing arm 40 can be prevented from interfering with the components in the case 10 during the telescopic process.

Further, a rotating shaft 430 is connected between the telescopic end 41 and the connecting end 42, and the swing arm 40 is hinged to the housing 10 through the rotating shaft 430. In this way, the swing arm 40 can swing around the rotation shaft 430 under the driving of the driving device 30, and the stability during the swing process is increased.

Referring again to fig. 2, the driving device 30 includes a driving member 31 and a link mechanism 320. The drive 31 is for example an electric motor. The linkage 320 includes a driving link 321 and a driven link 322, the driving link 321 is connected to the driving member 31, the driven link 322 has a first end 3221 and a second end 3222, the first end 3221 is hinged to the driving link 321, and the second end 3222 is hinged to the connecting end 42. In this way, the stability of the swing arm 40 during the swing can be increased by the driving link 321 and the driven link 322 connected to each other as transmission members.

As shown in fig. 3, the smoke collecting hood assembly 50 comprises a smoke collecting hood body 51, an illuminating lamp 52, an oil screen 53 and an oil cup 54, wherein the smoke collecting hood body 51 is provided with a far end 511 and a ring-shaped near end 512, the far end 511 is connected with the telescopic end 41, the oil screen 53 is provided with an oil cup connecting end 531 and an illuminating lamp connecting end 532, the oil cup 54 is connected to the oil cup connecting end 531, and the illuminating lamp 52 is a ring-shaped body and is arranged between the ring-shaped near end 512 and the illuminating lamp connecting end 532. Thus, the smoke collecting hood assembly 50 can collect oil stains and has an illumination function. Further, the illumination lamp 52 is a ring-shaped body, which is not only easy to install but also has a larger irradiation area.

As an exemplary embodiment, the smoke collecting cover body 51 has a circular truncated cone shape, and the outer diameter of the distal end 511 is smaller than that of the annular proximal end 512. Thus, the smoke collecting hood body 51 is more convenient for collecting smoke.

As an exemplary embodiment, the oil net 53 is in a circular truncated cone shape, and the outer diameter of the oil cup connection end 531 is smaller than that of the illumination lamp connection end 532. Thus, the oil screen can conveniently guide the oil stain into the oil cup 54 at the bottom of the oil screen.

Further, the lighting lamp 52 is provided with a distance sensor 70 electrically connected with the controller, the distance sensor 70 has a distance H1 with the bottom of the oil cup 54, and the distance sensor 70 is used for detecting the distance H2 between the smoke collecting hood 50 and the cooker 200 and transmitting a signal to the controller. Thus, the distance from the smoke collecting cover assembly 50 to the cooker 200 can be conveniently detected. The principle of the distance sensor 70 detecting the distance belongs to the prior art, and is not described herein in detail.

It should be understood that range hoods typically have a controller (the controller is not shown in the figures) to which the distance sensor 70, the drive member 31 and the telescoping drive member are electrically connected, respectively. The controller can control the action of the driving piece 31 based on the value fed back by the distance sensor 70, and can also control the telescopic driving piece to stretch and contract when controlling the action of the driving piece 31, so that the distance H3 is always kept between the distance sensor 70 and the top of the cooker, H3 is H2-H1, and H3 is set to be 25 cm-50 cm, thereby having good smoking effect and not influencing the sight of a user.

Because the conventional kitchen range is provided with the left and the right kitchen ranges, the left and the right kitchen ranges respectively correspond to the first cooking range 81 and the second cooking range 82 which are described later, and the distance between the left and the right kitchen ranges is generally 42 cm. As shown in fig. 5 and 6, when the side cooker is used, the smoke-collecting hood assembly 50 swings to smoke on the side; when the cookers on the two sides are used simultaneously, the smoke collecting hood assembly 50 swings to the middle, and smoke can be sucked on the two sides simultaneously.

Referring to fig. 4, 5 and 6 again, the smoke-collecting hood body 51 has a maximum outer diameter D1, a first cooking range 81, a second cooking range 82 and a pot center 83 are arranged below the cabinet 10, a distance L1 is arranged between the pot center 83 and the wall 300 for fixing the cabinet 10, a distance D3 is arranged between the first cooking range 81 and the second cooking range 82, and a pot 200 with a diameter D2 can be arranged on the first cooking range 81 or the second cooking range 82, wherein D3-D2 is not less than D1 is not less than 2 × L1. Therefore, the smoke collection cover body 50 can be just opposite to the center of the cookware, and the smoke collection cover body can also have a good smoking effect when the cookware corresponding to the first cooking range 81 and the cookware corresponding to the second cooking range 82 are opened simultaneously.
