[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

If the specific posture changes, the directional indications will also change accordingly.

[0032] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0033] The utility model provides a range hood.

[0034] Reference Figure 1 In one embodiment of the utility model, the range hood comprises:

[0035] The housing 1 is provided with a smoke inlet 100;

[0036] A driving mechanism 6, disposed on the housing 1; and

[0037] The smoke collecting plate 5 is connected to the driving mechanism 6 , and the smoke collecting plate 5 is suitable for opening and closing the smoke inlet 100 under the drive of the driving mechanism 6 .

[0038] For the convenience of subsequent description, the state in which the smoke collecting plate 5 closes the smoke inlet 100 is defined as the first state, and the state in which the smoke collecting plate 5 opens the smoke inlet 100 is defined as the second state.

[0039] It is understandable that during the long-term use of oil smoke extraction, oil smoke and other dirt will inevitably adhere to the housing 1. In normal times, the driving mechanism 6 usually drives the smoke collecting plate 5 to the first state, so as to shield the dirt in the housing 1 through the smoke collecting plate 5 and restrict external objects from extending into the housing 1 through the smoke inlet 100. When cooking with the stove below, the driving mechanism 6 drives the smoke collecting plate 5 to the second state, so as to extract oil smoke through the smoke inlet 100 and exhaust the oil smoke outdoors; and the smoke collecting plate 5 in the second state usually extends obliquely toward the front and lower side of the range hood, so as to form a smoke collecting cavity connected to the smoke inlet 100 between the smoke collecting plate 5 and the housing 1, reducing the probability of oil smoke overflow, thereby improving the oil smoke extraction effect of the range hood.

[0040] Refer to Figures 1 to 3, further, the driving mechanism 6 includes a driver 61, a driving arm 62 and a deflection mechanism 63. The driver 61 is arranged in the housing 1. The output shaft of the driver 61 is connected to the first end of the driving arm 62 to drive the driving arm 62 to rotate. The second end of the driving arm 62 is rotatably connected to the smoke collecting plate 5 at the first rotation axis. The deflection mechanism 63 is used to vertically deflect the smoke collecting plate 5 around the first rotation axis, so that the angle formed by the smoke collecting plate 5 and the second end of the driving arm 62 in the second state is smaller than the angle formed by the smoke collecting plate 5 and the second end of the driving arm 62 in the first state. It should be noted that the rotatable connection between the second end of the driving arm 62 and the smoke collecting plate 5 should be interpreted as that the smoke collecting plate 5 can be rotated relative to the second end of the driving arm 62, so that the size of the angle formed by the smoke collecting plate 5 and the second end of the driving arm 62 can be changed, and it is not intended to limit the direct connection between the smoke collecting plate 5 and the second end of the driving arm 62.

[0041] The technical solution of the utility model, through the action of the deflection mechanism 63, enables the smoke collecting plate 5 to form a smaller angle with the second end of the driving arm 62 in the second state, that is, the angle between the smoke collecting plate 5 and the plane where the smoke inlet 100 is located in the second state can be made smaller, so that the outward warping degree of the lower end of the smoke collecting plate 5 is smaller, thereby improving the smoke collecting effect of the smoke collecting plate 5, further improving the smoke extraction effect of the range hood, and reducing the outward warping distance of the lower end of the smoke collecting plate 5, so that the lower end of the smoke collecting plate 5 is farther away from the user performing the cooking operation, so as to avoid affecting the user's cooking field of view, increase the user's operating space, and improve the user experience.

[0042] Furthermore, in the process that the driver 61 drives the smoke collecting plate 5 to gradually open relative to the smoke inlet 100 through the driving arm 62, the deflection mechanism 63 is used to gradually deflect the smoke collecting plate 5 vertically around the first rotation axis, so that the opening trajectory of the lower end of the smoke collecting plate 5 is elliptical or quasi-elliptical. In the related art, the smoke collecting plate 5 is usually opened by rotating around a fixed point at the upper end, and the opening trajectory of the lower end of the smoke collecting plate 5 is circular. Compared with the circular opening trajectory in the related art, the elliptical or quasi-elliptical opening trajectory in the technical solution of the utility model occupies less space in front of the smoke inlet 100 during the opening process of the smoke collecting plate 5, thereby reducing the obstruction of the user's field of vision and reducing the probability of the lower end of the smoke collecting plate 5 hitting the user.

[0043] In one embodiment, referring to Figure 2 and Figure 3The deflection mechanism 63 includes a first upper pulling arm 631, a first end of the first upper pulling arm 631 is rotatably connected to the housing 1, a second end of the first upper pulling arm 631 is rotatably connected to the cigarette collecting plate 5, and a connection position between the first upper pulling arm 631 and the cigarette collecting plate 5 is closer to the upper end of the cigarette collecting plate 5 than a connection position between the driving arm 62 and the cigarette collecting plate 5. In this embodiment, generally, the connection position between the driving arm 62 and the cigarette collecting plate 5 is closer to the lower end of the cigarette collecting plate 5, and the connection position between the first upper pulling arm 631 and the cigarette collecting plate 5 is closer to the upper end of the cigarette collecting plate 5. When the driver 61 drives the driving arm 62 to rotate through its output shaft, the first upper pulling arm 631 can pull the upper end of the smoke collecting plate 5 upward, so that on the one hand, the downward angle formed by the opening of the smoke collecting plate 5 and the second end of the driving arm 62 becomes smaller, reducing the degree of outward warping of the lower end of the smoke collecting plate 5, and on the other hand, the smoke collecting plate 5 can be displaced upward as a whole, thereby further increasing the user's cooking operation space and improving the user experience. In this embodiment, usually, the length of the first upper pulling arm 631 is less than the length of the driving arm 62.

[0044] However, the present design is not limited to this. In some other embodiments, when the connection position between the driving arm 62 and the smoke collecting plate 5 is close to the upper end of the smoke collecting plate 5, the deflection mechanism 63 may also be provided with a first lower pulling arm, the first end of the first lower pulling arm being rotatably connected to the outer shell 1, the second end of the first lower pulling arm being rotatably connected to the smoke collecting plate 5, and the connection position between the first lower pulling arm and the smoke collecting plate 5 is arranged closer to the lower end of the smoke collecting plate 5 relative to the connection position between the driving arm 62 and the smoke collecting plate 5; in this way, in the process that the driver 61 drives the driving arm 62 to rotate through its output shaft, the first lower pulling arm can pull the lower end of the smoke collecting plate 5 downward, thereby reducing the downward angle of the opening formed by the smoke collecting plate 5 and the second end of the driving arm 62, reducing the degree of outward warping of the lower end of the smoke collecting plate 5, improving the smoke collecting effect of the smoke collecting plate 5, and improving the smoke collecting effect of the range hood; in this embodiment, usually, the length of the first lower pulling arm is greater than the length of the driving arm 62.

[0045] In some other embodiments, the upper pulling arm or the lower pulling arm may not be provided. In this case, the deflection mechanism 63 includes a deflection motor, which is fixedly mounted at the second end of the driving arm 62. The output shaft of the deflection motor is connected to the smoke collecting plate 5 to drive the smoke collecting plate 5 to vertically deflect. The first rotation axis is the axis of the output shaft of the deflection motor. In this way, by actively driving the smoke collecting plate 5 to vertically deflect relative to the first rotation axis, the downward angle of the opening formed by the smoke collecting plate 5 and the second end of the driving arm 62 can be reduced, thereby reducing the degree of outward warping of the lower end of the smoke collecting plate 5, improving the smoke collecting effect of the smoke collecting plate 5, and improving the smoke collection effect of the range hood.

[0046] For the embodiment with the first upper pull arm 631, further, referring to Figure 2 and Figure 3 , the deflection structure also includes a second upper pulling arm 632 and a transmission rod 633. The second upper pulling arm 632 is arranged on both lateral sides of the cigarette collecting plate 5 opposite to the first upper pulling arm 631. The first end of the second upper pulling arm 632 is rotatably connected to the shell 1, and the second end of the second upper pulling arm 632 is rotatably connected to the cigarette collecting plate 5. One end of the transmission rod 633 is fixedly connected to the first end of the first upper pulling arm 631, and the other end is fixedly connected to the first end of the second upper pulling arm 632, so that the second upper pulling arm 632 rotates synchronously with the first upper pulling arm 631, so that the lateral sides of the cigarette collecting plate 5 can rotate synchronously to open and close, and the opening and closing process is smoother, reducing the possibility of deformation of the cigarette collecting plate 5.

[0047] Further, refer to Figure 2 The driving mechanism 6 further includes a driven arm 64, which is disposed on both lateral sides of the cigarette collecting plate 5 opposite to the driving arm 62. The first end of the driven arm 64 is rotatably connected to the housing 1, and the second end of the driven arm 64 is rotatably connected to the cigarette collecting plate 5. In this way, the opening and closing process of the cigarette collecting plate 5 is smoother, reducing the possibility of deformation of the cigarette collecting plate 5. Optionally, the structure of the driven arm 64 is the same as that of the driving arm 62, so as to reduce the material styles required to be prepared, which is beneficial to the production of products.

[0048] Further, refer to Figure 2 and Figure 3The driving arm 62 and the first upper pulling arm 631 are both bent, and the opening formed by the bending is upward in the first state; thus, the upper end of the cigarette collecting plate 5 can be easily moved to the upper side of the smoke inlet 100, thereby raising the position of the cigarette collecting plate 5 as a whole and reducing the occupation of the user's operating space by the cigarette collecting plate 5. Similarly, the driven arm 64 and the second upper pulling arm 632 are also bent.

[0049] Furthermore, the driving arm 62 and the first upper pulling arm 631 are arranged near one side of the smoke collecting plate 5 in the transverse direction. The driving arm 62 and / or the first upper pulling arm 631 are arranged in a plate shape to improve the ability of the driving arm 62 and / or the first upper pulling arm 631 to limit the leakage of oil smoke from the side of the smoke collecting chamber, thereby further improving the oil smoke absorbing effect of the range hood. Similarly, the driven arm 64 and / or the second upper pulling arm 632 are also arranged in a plate shape.

[0050] Optionally, refer to Figures 1 to 4 , in the second state, the driving arm 62 and the first upper pulling arm 631 are spliced ​​in the up-down direction. It should be noted that the splicing referred to here can be the lower edge of one being spliced ​​with the upper edge of the other; or the upper edge of one being higher than the upper edge of the other, and the lower edge of the former extending to the middle position of the other. It can be understood that splicing is conducive to increasing the smoke blocking ability on the side of the smoke collecting chamber, thereby further reducing the oil smoke leaking from the side of the smoke collecting chamber and improving the oil smoke suction effect of the range hood. Similarly, in the second state, the driven arm 64 and the second upper pulling arm 632 are also spliced ​​in the up-down direction. Further optionally, in the second state, the first upper pulling arm 631 and the driving arm 62 are at least partially stacked to avoid a splicing gap between the two to reduce oil smoke leakage. Further optionally, a splicing groove 621 is provided on the side of the driving arm 62. In the second state, the lower edge of the first upper pulling arm 631 overlaps the splicing groove 621, so that the splicing sealing effect is better.

[0051] Further, refer to Figures 1 to 3 The range hood further comprises a first mounting seat 71 connected to the housing 1, the driver 61 is connected to the first mounting seat 71, and the first end of the first upper pull arm 631 is rotatably connected to the first mounting seat 71; it can be understood that by adding the first mounting seat 71, the connection between the drive mechanism 6 and the housing 1 can be more conveniently achieved. Optionally, the first mounting seat 71 is configured as a sheet metal stamping part, which has a high strength and is conducive to providing stable support for the drive mechanism 6, and the sheet metal process is conducive to the mass production of products; however, the present design is not limited thereto, and in other embodiments, the first mounting seat 71 can also be configured as a casting, etc.

[0052] Further, refer to Figures 2 to 5 The range hood further comprises a second mounting seat 8 connected to the smoke collecting plate 5, and the second end of the driving arm 62 and the second end of the first upper pulling arm 631 can be rotatably connected to the second mounting seat 8; it can be understood that by adding the second mounting seat 8, the connection between the driving mechanism 6 and the smoke collecting plate 5 can be more conveniently achieved. Optionally, the second mounting seat 8 comprises a first bracket 81 and a second bracket 82 connected to each other, and the first bracket 81 and the second bracket 82 are connected in a bent manner, and the first bracket 81 is installed in close contact with the smoke collecting plate 5, and the area of ​​the close contact installation is large, which can improve the installation stability; the second end of the driving arm 62 and the second end of the first upper pulling arm 631 can be rotatably connected to the second bracket 82; usually, the second bracket 82 is perpendicular or nearly perpendicular to the first bracket 81.

[0053] Optionally, the range hood further comprises a mounting cover plate 9 disposed on the back of the smoke collecting plate 5, a slot 91 with a lateral opening is formed between the mounting cover plate 9 and the smoke collecting plate 5, and the first bracket 81 is inserted into the slot 91 to be mounted with the smoke collecting plate 5. However, the present design is not limited thereto, and in other embodiments, the first bracket 81 may also be connected to the smoke collecting plate 5 by, but not limited to, welding or screw locking.

[0054] Optionally, the second bracket 82 is detachably connected to the first bracket 81. In this way, the first bracket 81 can be first installed on the cigarette collecting plate 5, and the second bracket 82 can be installed on the driving mechanism 6. Then, the cigarette collecting plate 5 can be installed on the second bracket 82 through the first bracket 81, so as to achieve connection with the driving mechanism 6. In this way, assembly is more convenient. Further, optionally, one end of the first bracket 81 is bent to provide a mounting flange 811, and the second bracket 82 can be detachably installed on the mounting flange 811. Optionally, one of the mounting flange 811 and the second bracket 82 is provided with a positioning rib 812, and the other is provided with a positioning hole 821. The first bracket 81 and the second bracket 82 are pre-positioned by the cooperation of the positioning rib 812 and the positioning hole 821, and then the mounting flange 811 and the second bracket 82 are fixed by fasteners, and the fasteners can be screws, rivets, etc.

[0055] Further, refer to Figure 1 and Figure 8The range hood further comprises a partition 72 disposed in the housing 1, the partition 72 partitioning the inner cavity of the housing 1 into an oil fume suction channel 10 and an installation cavity 60, the oil fume suction channel 10 is connected to the smoke inlet 100, and the drive mechanism 6 is installed in the installation cavity 60; in this arrangement, since the installation cavity 60 and the oil fume suction channel 10 are independent of each other, oil fume will not enter the installation cavity 60, thereby preventing oil fume from accumulating on the drive mechanism 6, so that the drive mechanism 6 can be used normally for a long time, thereby increasing the service life of the drive mechanism 6. However, the present design is not limited thereto, and in other embodiments, the partition 72 may not be provided.

[0056] Optionally, the housing 1 includes a smoke hood 11 and a fan hood 12 disposed on the upper side of the smoke hood 11, and a smoke outlet 110 is disposed between the fan hood 12 and the smoke hood 11. Two partitions 72 are disposed relatively inside the smoke hood 11, and the two partitions 72 are disposed on opposite sides of the smoke outlet 110, and the width between the two partitions 72 is gradually reduced in the direction close to the smoke outlet 110, so that the partition 72 can guide the oil smoke airflow to the smoke outlet 110, thereby improving the smoothness of smoke exhaust, and at the same time avoiding the oil smoke airflow from forming vortices at the corners on both sides of the top of the smoke hood 11, thereby reducing noise. In this embodiment, the partition 72 is reused as a guide piece, which can save one part and make the product structure simpler.

[0057] Further, refer to Figures 1 to 6 The driver 61 is connected to a wire (not shown), and a wire-loading structure is provided on the driving arm 62. The wire is provided on the wire-loading structure. The wire is fixed by the wire-loading structure, which can prevent the wire from being pulled or interfered during the opening and closing of the cigarette collecting plate 5, reduce the risk of the wire breaking, and increase the service life of the product. It should be noted that the setting of the wire-loading structure can be applied to the driving mechanism 6 provided with the deflection mechanism 63, and can also be applied to the driving structure without the deflection mechanism 63.

[0058] Furthermore, the wiring structure includes a wire box 73 extending along the driving arm 62, and the wires are passed through the wire box 73. In this way, the wires can be hidden in the wire box 73 to avoid oil smoke accumulation on the wires, thereby further improving the service life of the wires.

[0059] Furthermore, the driving arm 62 includes an arm body 622, and a mounting portion 623 connected to the lower side of the arm body 622. The wire box 73 is provided with a wire groove 731 opened to one side. The mounting portion 623 covers the notch of the wire groove 731, and the wire is passed through the wire groove 731. In this embodiment, the mounting portion 623 can provide support for the installation of the wire box 73, and the channel for the wire to pass through is formed by splicing the mounting portion 623 and the wire groove 731. The wire can be conveniently loaded into the long notch of the wire groove 731, and then the wire box 73 and the mounting portion 623 are connected and fixed, which is conducive to improving production efficiency. Optionally, the thickness of the mounting portion 623 is thinner than that of the arm body 622, so as to form a positioning step 624 between the arm body 622 and the mounting portion 623, and the wiring box 73 is positioned against the positioning step 624. In this way, on the one hand, it is easy to judge whether the wiring box 73 is installed in place, and on the other hand, it can also reduce the protruding height of the wiring box 73 relative to the arm body 622, so that the two look more like an integrated setting.

[0060] Furthermore, the wire box 73 is detachably connected to the driving arm 62 to facilitate the inspection of the wire. Optionally, the wire box 73 is provided with a connecting lug 732, and the connecting lug 732 is connected to the driving arm 62 by a fastener, so that the connection reliability between the wire box 73 and the driving arm 62 can be improved; however, the present design is not limited to this, and in other embodiments, the wire box 73 and the driving arm 62 can also be connected by a snap structure but not limited to. Optionally, a plurality of connecting lugs 732 are provided at intervals along the extension direction of the wire box 73, so that the wire box 73 can be well fixed at each position in the length direction, reducing the probability of the end of the wire box 73 being lifted or the middle being arched.

[0061] Furthermore, the range hood further comprises a control panel (not shown) and a mounting cover 9, wherein the control panel is mounted on the back of the smoke collecting plate 5, the mounting cover 9 covers the control panel, and the wire is also connected to the control panel, so that the smoke collecting plate 5 not only has the function of collecting smoke, but can also be used as a display and control component, and the smoke collecting plate 5 will be closer to the user when opened, which can facilitate the user to control the range hood. In this embodiment, optionally, the smoke collecting plate 5 is configured as a glass panel so that the display and control components on the control panel can be clearly displayed; however, the present design is not limited thereto, and in other embodiments, the smoke collecting plate 5 can also be configured as other panels, in which case, the smoke collecting plate 5 usually needs to open a window corresponding to the control panel so that the display and control components of the control panel can be exposed.

[0062] Optionally, the mounting cover plate 9 is provided with a wire opening 92 for the wire to pass through, and the wire box 73 extends to the wire opening 92 and covers the wire opening 92, so that the wire opening 92 can be further prevented from being exposed. Further optionally, the edge of the wire opening 92 is provided with an abutting flange 93, and the abutting flange 93 abuts against the wire box 73, so as to facilitate the sealing between the wire opening 92 and the wire box 73, and prevent oil smoke from entering from the wire opening 92 and contaminating the control panel.

[0063] In one embodiment, referring to Figure 7 and Figure 8 The range hood further comprises a flow dividing structure 2, which is arranged in the oil fume suction channel 10, and is used to divide the oil fume suction channel 10 into a left channel 10a and a right channel 10b. The flow dividing structure 2 is usually arranged near the smoke inlet 100, so as to divide the oil fume suction channel 10 into a left channel 10a and a right channel 10b inside the smoke inlet 100, thereby effectively reducing the vortex caused by the collision of two streams of oil smoke entering the oil fume suction channel 10 from both sides of the smoke inlet 100, improving the smoothness of oil smoke passing through the oil fume suction channel 10, thereby improving the smoke extraction effect of the range hood and reducing noise.

[0064] In one embodiment, the diverter structure 2 can be configured as a structure that is fixed as a whole relative to the housing 1, that is, the diverter structure 2 can be a fixed structure fixed in the oil fume suction channel 10. However, the present design is not limited thereto. In other embodiments, the diverter structure 2 can also be configured as a structure that at least partially rotates relative to the housing 1 (see Figure 8 ) to adjust the size of the left channel 10a and the right channel 10b through the rotating part.

[0065] For the embodiment of the flow dividing structure 2 which is at least partially rotated relative to the housing 1, refer to Figure 7 and Figure 8 The diversion structure 2 may include a rotating part 21 rotatably disposed in the oil fume suction channel 10, so as to adjust the size of the left channel 10a and the right channel 10b through the rotating part 21, thereby adjusting the oil fume suction capacity of the left channel 10a and the right channel 10b. It should be noted that the adjustment of the size of the left channel 10a and the right channel 10b referred to here does not mean adjusting the size of all positions in the left channel 10a and the right channel 10b, but means adjusting the size of the minimum connecting cross-section of the left and right channels and the right channel 10b. The minimum connecting cross-section is the throat of the corresponding channel, and its size is proportional to the suction capacity of the corresponding channel.

[0066] When the rotating part 21 rotates relative to the left channel 10a, the oil fume absorption capacity of the left channel 10a can be reduced, and the oil fume absorption capacity of the right channel 10b can be increased. When the rotating part 21 rotates relative to the right channel 10b, the oil fume absorption capacity of the right channel 10b can be reduced, and the oil fume absorption capacity of the left channel 10a can be increased. For a gas stove with two burners, a user may only use one of the left and right burners for cooking, resulting in a large amount of oil smoke being generated under one of the left channel 10a and the right channel 10b, and a small amount of oil smoke being diffused under the other. Alternatively, when a user uses both the left and right burners for cooking, one burner is performing operations such as frying that generate a large amount of oil smoke, while the other burner is performing operations such as stewing that generate a small amount of oil smoke, resulting in a large amount of oil smoke being generated under one of the left channel 10a and the right channel 10b, and a small amount of oil smoke being generated under the other. In this case, the channel corresponding to the side with a large amount of oil smoke can be enlarged and the channel corresponding to the side with a small amount of oil smoke can be reduced by rotating the rotating part 21, thereby improving the oil smoke absorption capacity of the channel corresponding to the side with a large amount of oil smoke, while reducing the oil smoke absorption capacity of the channel corresponding to the side with a small amount of oil smoke, thereby improving the oil smoke absorption effect of the range hood.

[0067] It is worth mentioning that the rotation control of the rotating part 21 can be manually controlled by the user according to the size of the oil smoke, or the range hood can be automatically controlled by setting an oil smoke monitoring device for detecting the size of the oil smoke on the corresponding side and configuring a controller according to the detection result of the oil smoke monitoring device.

[0068] In addition, in the present invention, the rotating portion 21 can be directly rotatably connected to the housing 1 or indirectly rotatably connected to the housing 1 .

[0069] For the embodiment indirectly connected to the housing 1, the flow dividing structure 2 further comprises a fixed portion 22 connected to the housing 1, and the rotating portion 21 is rotatably connected to the fixed portion 22 (see Figure 8 ). The fixed part 22 not only provides a mounting support for the rotating part 21 to be rotatably connected, but also has the function of separating the oil fume suction channel 10, thereby more effectively reducing the vortex caused by the collision of two streams of oil smoke entering the oil fume suction channel 10 from both sides of the smoke inlet 100, and better improving the smoothness of oil smoke passing through the oil fume suction channel 10. In addition, the space in the fixed part 22 can also be used to install a driving mechanism for driving the rotating part 21 to rotate, so as to isolate the oil fume for the driving mechanism through the shell of the fixed part 22, avoid the oil fume from being deposited on the driving structure, and thus extend the service life of the driving mechanism.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
