Description

Technical Field

[0001] The embodiments of the present application belong to the technical field of kitchen appliances, and specifically relate to a range hood. Background Art

[0002] A range hood is usually installed above the kitchen stove. It can output the exhaust gas from the stove and the fumes generated during the cooking process to the outside, thereby improving the air quality in the kitchen.

[0003] In the related art, there is a side-suction range hood with a rotatable baffle, and the baffle has an open state and a closed state. When the baffle is in the open state, the baffle opens the smoke inlet, allowing the exhaust gas from the combustion of the stove and the oil smoke and other gases generated during the cooking process to enter the range hood through the smoke inlet and be discharged to the public flue or the outdoor environment. When the baffle is in the closed state, the baffle blocks the smoke inlet.

[0004] However, the baffle has a poor smoke-collecting effect when it is in the open state. Utility Model Content

[0005] The main purpose of the embodiments of the present application is to provide a range hood to solve the problem that the baffle of the related range hood has a poor smoke-collecting effect when it is in an open state.

[0006] To achieve the above object, the present application provides a range hood, comprising:

[0007] A housing having a smoke inlet side, the smoke inlet side defining a smoke inlet port;

[0008] The baffle assembly includes a baffle and a shielding member. The baffle is rotatably connected to the shell. When the baffle is in a closed state, it is located in front of the smoke inlet side and has a preset interval with the smoke inlet side. The shielding member is arranged on a side of the baffle close to the smoke inlet side and shields the preset interval and the smoke inlet.

[0009] In a possible implementation, the shielding member is spaced apart from the edge of the baffle, and when the baffle is in a closed state, the shielding member is located at the periphery of the smoke inlet.

[0010] In one possible implementation, the front end of the shell has a front wall, which is located on the periphery of the smoke inlet side, and the smoke inlet side is closer to the rear end of the shell than the front wall; the baffle is arranged in front of the front wall, and the end of the shielding member facing away from the baffle extends between the smoke inlet side and the front wall.

[0011] In a possible implementation, the baffle assembly also includes a rear shell, which is arranged on a side of the baffle close to the smoke inlet side, and the shielding member shields the side of the rear shell; the rear shell and at least part of the baffle form an electric control cavity; the range hood includes a controller, which is arranged in the electric control cavity.

[0012] In a possible implementation, the rear housing has a rear panel and a bottom plate. The rear panel is disposed opposite to the baffle. One end of the bottom plate is connected to the bottom end of the rear panel, and the other end of the bottom plate is connected to the baffle. When the baffle is in the closed state, the bottom end of the rear panel extends into the smoke inlet, and the bottom plate slopes upward from the end close to the rear panel to the end close to the baffle.

[0013] In a possible implementation, the range hood includes a hinge, a support rod, and a driving device. The top end of the baffle is rotatably connected to the housing through the hinge. The driving device is disposed inside the housing, and the support rod is disposed between the driving device and the baffle. The support rod drives the baffle assembly to open or block the smoke inlet under the drive of the driving device.

[0014] In a possible implementation, the range hood further includes a partition, a main housing, and a fan. An oil smoke cavity communicating with the smoke inlet is provided inside the housing, and a smoke outlet communicating with the oil smoke cavity is provided at the top of the housing. The partition is disposed at the front end of the top of the housing. The main housing is disposed on the top of the smoke outlet and the partition, and the fan is disposed inside the main housing.

[0015] In a possible implementation, the fan has an air inlet and an air outlet. The air inlet faces the rear wall of the main housing and is spaced from the rear wall, and the air outlet extends to the top wall of the main housing.

[0016] In a possible implementation, the housing has a first bracket, a second bracket, and two first side plates disposed opposite to each other. The first bracket is disposed on the top of the second bracket, and the two first side plates are located on both sides of the whole formed by the first bracket and the second bracket. The first bracket, the second bracket, and the first side plates enclose a smoke collecting cavity. The front end of the first side plate has a first flanging extending in a direction away from the smoke collecting cavity, and the first flanging forms the smoke inlet side. The edge of one end of the smoke collecting cavity close to the smoke inlet side forms the smoke inlet. The range hood further includes an oil net, and the oil net is detachably disposed on the first bracket.

[0017] In a possible implementation, the range hood further includes a lighting device, and the lighting device is disposed on the first bracket.

[0018] Those skilled in the art can understand that the range hood of the embodiment of the present application includes a housing and a baffle assembly. The housing has a smoke inlet side, and a smoke inlet is defined on the smoke inlet side. The baffle assembly includes a baffle and a shielding member. The baffle is rotatably connected to the housing. When the baffle is in the closed state, it is located in front of the smoke inlet side and has a preset interval from the smoke inlet side. The shielding member is arranged on the side of the baffle close to the smoke inlet side and shields the preset interval and the smoke inlet. Through the above settings, when the baffle is in the closed state, there is a preset interval between the baffle and the smoke inlet side. When the baffle is in the open state, the distance between the baffle and the smoke inlet side is the sum of the horizontal distance turned by the bottom end of the baffle and the preset gap, so that the distance between the bottom end of the baffle and the smoke inlet side increases by the preset interval when the baffle is in the open state. Without changing the horizontal length of the baffle, the smoke-gathering range of the baffle is increased, thereby improving the smoke-gathering effect of the baffle when it is in the open state.

[0091] First of all, those skilled in the art should understand that these implementation manners are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application. Those skilled in the art can adjust them as needed to adapt to specific application scenarios.

[0092] Secondly, it should be noted that in the description of the embodiments of the present application, the terms indicating the direction or positional relationship such as "inner" and "outer" are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description, rather than indicating or implying that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the embodiments of the present application.

[0093] In addition, it should also be noted that in the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0094] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0095] As described in the background art, there is a problem of poor smoke collection effect when the baffle of the range hood in the related art is in the open state. After research by the inventor, it is found that the reason for this problem is that when the baffle is in the closed state, the outer surface of the baffle is usually flush with the front wall of the housing. Although this can improve the decorative effect of the range hood, it will cause the distance between the bottom end of the baffle and the front wall of the housing to decrease when the baffle is opened to the open state, that is, the smoke collection range of the baffle decreases, resulting in a reduction in the smoke collection effect when the baffle is in the open state.

[0096] To solve the above technical problems, the embodiments of the present application provide a range hood, which moves the baffle outward to the front of the smoke inlet side when the baffle is in the closed state, and a preset interval between the baffle and the smoke inlet side is blocked by a shroud provided on one side of the baffle. When the rotation angle of the baffle from the closed state to the open state remains unchanged, moving the baffle outward to the front of the smoke inlet side can increase the distance between the bottom end of the baffle and the smoke inlet side when the baffle is in the open state, thereby increasing the smoke collection range of the baffle and improving the smoke collection effect when the baffle is in the open state.

[0097] The principles and features of the embodiments of the present application will be described below with reference to the accompanying drawings. The examples given are only for explaining the embodiments of the present application and are not intended to limit the scope of the embodiments of the present application.

[0098] ReferenceFigure 1 and Figure 2 For the range hood provided in the embodiment of the present application, it includes a housing 1, and the housing 1 has a smoke inlet side 11. The smoke inlet side 11 defines a smoke inlet 12.

[0099] In some possible implementation manners of the embodiment of the present application, with reference to Figure 1 and Figure 2 , the smoke inlet side 11 may extend in the vertical direction.

[0100] In some possible implementation manners of the embodiment of the present application, the smoke inlet side 11 may be inclined relative to the vertical direction.

[0101] Exhaust gas generated by the combustion of the cooking appliance and gases such as cooking fumes during the cooking process enter the housing 1 through the smoke inlet 12 and are discharged by the range hood to a common flue or the outdoor environment, so as to reduce the amount of exhaust gas and cooking fumes in the kitchen environment and improve the air quality of the kitchen.

[0102] With reference to Figure 3 and Figure 4 , the range hood further includes a baffle assembly 2, and the baffle assembly 2 is rotatably connected to the housing 1 to open or block the smoke inlet 12.

[0103] The baffle assembly 2 may have an open state and a closed state.

[0104] When the baffle assembly 2 is in the closed state (with reference to Figure 3 ), the baffle assembly 2 blocks the smoke inlet 12.

[0105] When the baffle assembly 2 is in the open state (with reference to Figure 4 ), the baffle assembly 2 opens the smoke inlet 12 and the baffle assembly 2 rotates to the maximum opening angle.

[0106] The baffle assembly 2 includes a baffle 21, and the baffle 21 is rotatably connected to the housing 1.

[0107] With reference to Figure 5 and Figure 6 , exemplarily, the top end of the baffle 21 may be rotatably connected to the housing 1 through a hinge 73, so that the baffle 21 can rotate relative to the housing 1.

[0108] In the embodiment of the present application, when the baffle assembly 2 is in the open state, the baffle 21 is also in the open state; when the baffle assembly 2 is in the closed state, the baffle 21 is also in the closed state.

[0109] In the implementation manner where the smoke inlet side 11 extends in the vertical direction, when the baffle assembly 2 is in the closed state, the baffle 21 also extends in the vertical direction.

[0110] In the implementation where the smoke inlet side 11 is inclined relative to the vertical direction, when the baffle assembly 2 is in the closed state, the baffle 21 is also inclined relative to the vertical direction.

[0111] Reference Figure 1 、 Figure 7 and Figure 8 , when the baffle 21 is in the closed state, the baffle 21 is located in front of the smoke inlet side 11, and there is a preset interval D between the baffle 21 and the smoke inlet side 11. Among them, the baffle 21 being located in front of the smoke inlet side 11 means that the baffle 21 is farther from the back plate 110 of the housing 1 than the smoke inlet side 11, and the back plate 110 of the housing 1 is used to face the wall.

[0112] The following embodiments are described by taking the smoke inlet side 11 extending in the vertical direction as an example.

[0113] When the baffle 21 rotates from the closed state to the open state, the rotation angle of the baffle 21 is less than 90°, reference Figure 4 and Figure 6 , when the baffle 21 is in the open state, the included angle between the baffle 21 and the vertical direction is less than 90°.

[0114] When the baffle 21 is in the closed state, the distance between the baffle 21 and the smoke inlet side 11 is the preset interval D.

[0115] When the baffle 21 is in the open state, the distance between the baffle 21 and the smoke inlet side 11 is the sum of the horizontal distance turned by the bottom end of the baffle 21 and the preset gap. When the rotation angle of the baffle 21 from the closed state to the open state remains unchanged, the horizontal distance turned by the bottom end of the baffle 21 also remains unchanged. In the embodiments of the present application, the distance between the bottom end of the baffle 21 and the smoke inlet side 11 in the open state of the baffle 21 is increased by the preset interval D. Without changing the horizontal length of the baffle 21, the smoke-gathering range of the baffle 21 is increased, thereby improving the smoke-gathering effect of the baffle 21 in the open state.

[0116] Reference Figure 8 and Figure 9 , the baffle assembly 2 further includes a shielding member 24. The shielding member 24 can be a shielding plate or a shielding sheet, etc. The shielding member 24 is arranged on the side of the baffle 21 close to the smoke inlet side 11. The shielding member 24 shields at the preset interval D when the baffle assembly 2 is in the closed state, so that the smoke inlet 12 is not easily observed from the outside of the range hood, thereby improving the decorative effect of the range hood.

[0117] In some possible implementation manners of the embodiments of the present application, the shielding member 24 can be arranged at an interval relative to the edge of the housing 1, so that there is a certain interval between the shielding member 24 and the edge of the housing 1, making it not easy to observe the shielding member 24 from the outside of the range hood and improving the decorative effect of the range hood.

[0118] In some possible implementations of the embodiments of the present application, when the baffle 21 is in a closed state, the shielding member 24 may be located at the periphery of the smoke inlet 12 , which can improve the shielding effect of the shielding member 24 on the smoke inlet 12 .

[0119] In some possible implementations of the present application, reference is made to Figure 1 , Figure 2 and Figure 4 The front end of the housing 1 may have a front wall 13, and the front wall 13 is located at the periphery of the smoke inlet side 11. The front end of the housing 1 refers to the side of the housing 1 that is away from the back plate 110.

[0120] In some possible implementations of the embodiments of the present application, the smoke inlet side 11 is closer to the rear end of the housing 1 than the front wall 13 , that is, the smoke inlet side 11 is recessed relative to the front wall 13 .

[0121] refer to Figure 8 and Figure 9 When the baffle 21 is in the closed state, the baffle 21 is arranged in front of the front wall 13, and there is also a gap d between the baffle 21 and the front wall 13, and the gap d between the baffle 21 and the front wall 13 is smaller than the preset gap D between the smoke inlet side 11 and the baffle 21.

[0122] One end of the shielding member 24 facing away from the baffle 21 extends to between the smoke inlet side 11 and the front wall 13, that is, the interval between the end of the shielding member 24 facing away from the baffle 21 and the smoke inlet side 11 is smaller than the interval between the smoke inlet side 11 and the front wall 13. When the baffle 21 is in a closed state, part of the shielding member 24 is hidden between the front wall 13 and the smoke inlet side 11, making it difficult to observe the interval between the shielding member 24 and the smoke inlet side 11 from the outside of the range hood, thereby improving the decorative effect of the range hood.

[0123] In some possible implementations of the present application, reference is made to Figure 9 When the baffle assembly 2 is in a closed state, the top end of the shielding member 24 can extend to the top end of the baffle 21 , and the bottom end of the shielding member 24 can extend to the bottom end of the baffle 21 to improve the shielding effect on the smoke inlet 12 .

[0124] In some possible implementations of the present application, reference is made to Figure 9 The bottom end of the shielding member 24 may have a certain distance from the bottom end of the baffle 21, so that when the baffle assembly 2 is in the open state, the shielding member 24 is located below the baffle 21, and the bottom end of the shielding member 24 is closer to the front wall 13 relative to the bottom end of the baffle 21, thereby reducing the horizontal distance that the shielding member 24 extends from the front wall 13, making it difficult for the bottom end of the shielding member 24 to hit the head.

[0125] In some possible implementations of the present application, reference is made to Figure 6 , Figure 8 and Figure 10, the baffle assembly 2 may further include a rear housing 22. The rear housing 22 is disposed on the side of the baffle 21 close to the smoke inlet side 11, and the shielding member 24 shields the side of the rear housing 22. Exemplarily, there may be two shielding members 24, and the two shielding members 24 respectively shield the two sides of the rear housing 22 along the length direction of the range hood, making it difficult to observe the rear housing 22 from the outside of the range hood and improving the decorative effect of the range hood.

[0126] The rear housing 22 and at least a part of the baffle 21 enclose an electronic control cavity 23. The range hood may further include a controller 71. The controller 71 is disposed in the electronic control cavity 23. Compared with disposing the controller 71 at other positions of the range hood, disposing the controller 71 in the electronic control cavity 23 enclosed by the baffle assembly 2 saves more space occupied by the controller 71. The baffle 21 may be provided with a touch area or control buttons, and both the touch area and the control buttons are electrically connected to the controller 71. The controller 71 is controlled through the touch area or the control buttons to implement function selection of the range hood.

[0127] In some possible implementation manners of the embodiments of the present application, with reference to Figure 8 and Figure 10 , the rear housing 22 may have a rear plate 221 and a bottom plate 222. The rear plate 221 is disposed opposite to the baffle 21. One end of the bottom plate 222 is connected to the bottom end of the rear plate 221, and the other end of the bottom plate 222 is connected to the baffle 21.

[0128] When the baffle assembly 2 is in the closed state, the bottom end of the rear plate 221 extends into the housing 1. In this way, when the oil droplets on the rear plate 221 flow down to the bottom end of the rear plate 221, they will continue to flow down into the housing 1 and be collected in the oil cup 72, so that the oil liquid on the rear plate 221 is not likely to drip from the bottom end of the rear plate 221 onto the kitchen countertop.

[0129] The bottom plate 222 is inclined upward from the end close to the rear plate 221 to the end close to the baffle 21, that is, the height of the end of the bottom plate 222 close to the rear plate 221 is lower than the height of the end of the bottom plate 222 close to the baffle 21. With such a setting, on the one hand, it is difficult for the oil liquid flowing down along the rear plate 221 to the bottom end of the rear plate 221 to flow onto the bottom plate 222; on the other hand, the oil droplets attached to the surface of the bottom plate 222 can flow down along the inclined bottom plate 222 to the bottom end of the rear plate 221 and flow down from the bottom end of the rear plate 221 into the housing 1 and finally be collected in the oil cup 72, so that the oil droplets on the bottom plate 222 are not likely to drip onto the kitchen countertop.

[0130] In some possible implementation manners of the embodiments of the present application, with reference to Figure 8 and Figure 10 , the rear housing 22 may have a top plate 224. The top plate 224 is located at the top of the rear housing 22. One end of the top plate 224 is connected to the top end of the rear plate 221, and the other end of the top plate 224 is connected to the baffle 21.

[0131] refer to Figure 8 When the baffle assembly 2 blocks the smoke inlet 12, the top plate 224 tilts downward from the end close to the baffle 21 to the end close to the rear plate 221, that is, the height of the end of the top plate 224 close to the baffle 21 is higher than the height of the end of the top plate 224 close to the rear plate 221. The tilted top plate 224 can guide the oil, and the oil droplets on the surface of the top plate 224 and the oil droplets flowing to the top plate 224 along the baffle 21 above the top plate 224 can flow downward along the tilted top plate 224 to the top of the rear plate 221, flow downward along the rear plate 221 into the shell 1, and are finally collected by the oil cup 72.

[0132] In some possible implementations of the present application, reference is made to Figure 8 and Figure 10 The rear shell 22 may have two opposite second side plates 225, and the top plate 224, the bottom plate 222 and the two second side plates 225 are arranged around the periphery of the rear plate 221 to form a rear shell 22 with an opening. The baffle 21 blocks the opening of the rear shell 22 and forms an electric control chamber 23 with the rear shell 22, so that gas such as oil smoke and oil droplets are not easy to flow into the electric control chamber 23, thereby protecting the controller 71 in the electric control chamber 23.

[0133] In some possible implementations of the present application, reference is made to Figures 10 - 13 The bottom end of the shielding member 24 may have a first flange 241 extending toward the rear housing 22, and the first flange 241 is located at the bottom of the bottom plate 222. The first flange 241 may be configured with a first connection hole 242, and the bottom plate 222 may be configured with a second connection hole 223. The first flange 241 and the bottom plate 222 may be connected by a first fastener 243 penetrating through the first connection hole 242 and the second connection hole 223. The first fastener 243 may be a fastening bolt or other components that may be penetrating through the first connection hole 242 and the second connection hole 223 and fix the first flange 241 and the bottom plate 222.

[0134] In some possible implementations of the present application, reference is made to Figure 11 and Figure 13 The first flange 241 may be constructed with a first boss 242, the first boss 242 protruding toward the bottom plate 222, and the first connecting hole 242 is constructed at one end of the first boss 242 close to the bottom plate 222 to increase the distance between the first connecting hole 242 and the first flange 241, so that the oil on the side of the first flange 241 away from the bottom plate 222 is not easy to flow through the first connecting hole 242 to between the first flange 241 and the bottom plate 222.

[0135] In some possible implementation manners of the embodiments of the present application, the bottom end of the shielding member 24 may extend to the bottom plate 222, and the top end of the shielding member 24 may extend to the top end of the baffle 21. That is to say, the shielding member 24 extends from the bottom end of the second side plate 225 to the top end of the baffle 21, so as to shield the entire second side plate 225 and the area between the top end of the second side plate 225 and the top end of the baffle 21, making it difficult to observe the rear case 22 and the stepped structure formed by the rear plate 221, the top plate 224, and the baffle 21 from both sides of the baffle assembly 2, thereby improving the decorative effect of the range hood.

[0136] In some possible implementation manners of the embodiments of the present application, with reference to Figures 10 - 14 , a limiting portion 245 may be provided on one side of the shielding member 24 facing the second side plate 225, and the second side plate 225 is configured with a cooperating portion. The limiting portion 245 and the cooperating portion cooperate with each other to limit the second side plate 225 from moving downward and away from the shielding member 24 relative to the shielding member 24, thereby improving the connection stability between the shielding member 24 and the second side plate 225.

[0137] In some possible implementation manners of the embodiments of the present application, when the limiting portion 245 and the cooperating portion cooperate with each other, the first flanging 241 or the first connection hole 242 on the boss corresponds to the second connection hole 223 on the bottom plate 222.

[0138] When installing the shielding member 24 on the rear case 22, the limiting portion 245 and the cooperating portion are made to cooperate with each other to position the shielding member 24 and the second side plate 225, facilitating the first fastener 243 to be inserted into the first connection hole 242 and the second connection hole 223.

[0139] In some possible implementation manners of the embodiments of the present application, with reference to Figures 10 - 14 , the limiting portion 245 may include a first portion 246 and a second portion 247. The first portion 246 is connected to the shielding member 24, the second portion 247 is provided on the top of the first portion 246, and there is an insertion gap 248 between the second portion 247 and the shielding member 24.

[0140] The cooperating portion includes a limiting hole 226. After the limiting portion 245 is inserted into the limiting hole 226 and the shielding member 24 is moved upward, part of the second side plate 225 is inserted into the insertion gap 248. At this time, the second side plate 225 is not easily moved downward relative to the shielding member 24, and the second side plate 225 is inserted into the insertion gap 248, making the second side plate 225 not easily move away from the shielding member 24, thereby positioning the second side plate 225 and the shielding member 24.

[0141] In some possible implementation manners of the embodiments of the present application, with reference to Figures 10 - 14, the limiting hole 226 may include a first hole section 227, a transition hole section 228, and a second hole section 229 arranged in sequence from bottom to top. The length of the first hole section 227 along the thickness direction X of the limiting part 245 is greater than the length of the second hole section 229 along the thickness direction X. The length of the transition hole section 228 along the thickness direction X gradually decreases from the end close to the first hole section 227 to the end close to the second hole section 229.

[0142] When installing the shielding member 24 and the second side plate 225, the length of the first hole section 227 along the thickness direction X of the limiting part 245 is relatively large, so the limiting part 245 can more easily pass through the first hole section 227.

[0143] After the limiting part 245 passes through the first hole section 227, it moves upward along the transition hole section 228 and is clamped in the second hole section 229.

[0144] The length of the second hole section 229 along the thickness direction X of the limiting part 245 is less than the length of the first hole section 227 along the thickness direction X of the limiting part 245. Exemplarily, the length of the second hole section 229 along the thickness direction X of the limiting part 245 may be equal to or slightly greater than the length of the limiting part 245 in the thickness direction X. After the limiting part 245 is inserted into the first hole section 227, the swinging amplitude of the limiting part 245 along the thickness direction X of the limiting part 245 can be reduced, improving the connection stability between the shielding member 24 and the second side plate 225.

[0145] The length of the end of the transition hole section 228 close to the first hole section 227 along the thickness direction X of the limiting part 245 may be equal to the length of the first hole section 227 along the thickness direction X of the limiting part 245. The length of the end of the transition hole section 228 close to the second hole section 229 along the thickness direction X of the fiber cloth may be equal to the length of the second hole section 229 along the thickness direction X of the limiting part 245. The transition hole section 228 transitions the lengths of the first hole section 227 and the second hole section 229 along the thickness direction X of the limiting part 245, improving the smoothness of the part of the limiting part 245 sliding from the first hole section 227 into the second hole section 229.

[0146] In some possible implementation manners of the embodiments of the present application, referring to Figure 6 , the range hood may further include a hinge 73, a support rod 74, and a driving device.

[0147] The top end of the baffle 21 is rotatably connected to the housing 1 through the hinge 73.

[0148] The driving device is arranged in the housing 1, the support rod 74 is arranged between the driving device and the baffle 21, and the support rod 74 drives the baffle assembly 2 to open or block the smoke inlet 12 under the drive of the driving device. By driving the support rod 74 to rotate through the driving device, it is easier to make the support rod 74 drive the baffle assembly 2 to rotate.

[0149] In some possible implementation manners of the embodiments of the present application, referring to Figure 6 , the driving device may be a driving motor 75. The driving motor 75 is arranged in the housing 1. The driving motor 75 has a motor shaft 751. The support rod 74 is connected to the motor shaft 751 and rotates with the motor shaft 751. During the rotation of the support rod 74, the baffle assembly 2 is driven to rotate relative to the housing 1 to open or block the smoke inlet 12.

[0150] In some possible implementation manners of the embodiments of the present application, the support rod 74 may include a first rod 741 and a second rod 742. The first rod 741 and the second rod 742 are hinged. One end of the first rod 741 away from the second rod 742 may be hinged to the housing 1, and one end of the second rod 742 away from the first rod 741 may be hinged to the baffle 21.

[0151] In some possible implementation manners of the embodiments of the present application, the driving device may be an electric push rod. The electric push rod is arranged in the housing 1. The electric push rod has a telescopic rod. The axis of the support rod 74 may be parallel or collinear with the axis of the telescopic rod. One end of the support rod 74 is connected to the baffle 21, and the other end of the support rod 74 is connected to the telescopic rod and moves along the axis of the support rod 74 under the drive of the telescopic rod, so as to drive the baffle assembly 2 to rotate relative to the housing 1 to open or block the smoke inlet 12.

[0152] In some possible implementation manners of the embodiments of the present application, referring to Figure 15 , the range hood may further include a partition plate 3, a sealing plate 6, a main housing 4 and a blower 5.

[0153] The partition plate 3 is arranged at the front end of the top of the housing 1, that is, the partition plate 3 may extend along the front end of the top of the housing 1 in a direction away from the back plate 110 of the housing 1.

[0154] Part of the sealing plate 6 is arranged in the housing 1, and the other part of the sealing plate 6 extends to the top of the partition plate 3. That is, the front end of the sealing plate 6 may extend to the top of the partition plate 3, and the rear end of the sealing plate 6 may extend to the back plate 110.

[0155] The sealing plate 6 and the housing 1 enclose an oil smoke cavity 14 with an oil smoke outlet 15 at the top. The oil smoke cavity 14 is communicated with the smoke inlet 12. Gases such as oil smoke can enter the oil smoke cavity 14 from the smoke inlet 12.

[0156] Referring to Figure 16 and Figure 17, the sealing plate 6 above the partition plate 3 is located within the edge of the partition plate 3, that is, the projection of the sealing plate 6 above the partition plate 3 on the partition plate 3 is located within the edge of the partition plate 3, so that the partition plate 3 can receive the oil flowing down from the sealing plate 6, and the oil on the partition plate 3 can flow along the partition plate 3 to the oil fume outlet 15 of the oil fume cavity 14, and then flow downward along the inner wall of the oil fume cavity 14.

[0157] The range hood can include an oil cup 72, and the oil cup 72 can be arranged at the bottom of the housing 1 to collect the oil flowing down along the inner wall of the oil fume cavity 14.

[0158] Reference Figure 18 , the main box body 4 is arranged on the top of the housing 1 and the partition plate 3, and the main box body 4 covers the outside of the oil fume outlet 15, so that the main box body 4 and the oil fume cavity 14 are communicated through the oil fume outlet 15.

[0159] The main box body 4 is arranged on the top of the oil fume outlet 15 and the partition plate 3, and the main box body 4 can be configured with a smoke outlet 43, and the smoke outlet 43 is used to communicate with a common flue or the outdoor environment through a smoke exhaust pipe.

[0160] In the embodiment of the present application, the direction "front" refers to the direction horizontally pointing from the back plate 110 to the smoke inlet side 11, and the "rear" refers to the direction horizontally pointing from the smoke inlet side 11 to the back plate 110.

[0161] The fan 5 is arranged in the main box body 4. When the fan 5 works, a negative pressure is formed at the smoke inlet 12, and gases such as the exhaust gas of the cooking appliance combustion and the oil fume generated during the cooking process enter the oil fume cavity 14 through the smoke inlet 12. The oil fume and other gases in the oil fume cavity 14 enter the main box body 4 through the oil fume outlet 15. The oil fume and other gases in the main box body 4 flow to the smoke outlet 43 under the action of the fan 5 and are discharged from the smoke outlet 43, so as to reduce the amount of exhaust gas and oil fume in the kitchen environment and improve the air quality of the kitchen.

[0162] At least a part of the inner wall at the bottom of the main box body 4 is located inside the sealing plate 6, so that the sealing plate 6 blocks outside the inner wall at the bottom of the main box body 4, making it difficult for the oil flowing down along the inner wall of the main box body 4 to flow outside the sealing plate 6.

[0163] After the oil fume and other gases flow to the main box body 4, some of the oil droplets in the oil fume will adhere to the inner wall of the main box body 4 and the outer wall of the fan 5. As the amount of the adhered oil droplets gradually increases, the oil droplets will converge into an oil flow and flow downward to the inner wall of the housing 1 or the partition plate 3.

[0164] The sealing plate 6 above the partition plate 3 can guide the oil flowing down along the inner wall of the main box body 4 to the partition plate 3. The oil flowing to the partition plate 3 flows along the partition plate 3 to the edge of the partition plate 3 close to the oil fume outlet 15, and flows from this edge to the inner wall of the oil fume cavity 14, and finally flows into the oil cup 72 along the inner wall of the oil fume cavity 14 to be collected.

[0165] The sealing plate 6 located in the oil fume cavity 14 can guide the oil flowing down along the inner wall of the main box body 4 to the inner wall of the oil fume cavity 14, and finally flow into the oil cup 72 for collection.

[0166] Reference Figure 17 In some possible implementation manners of the embodiments of the present application, the partition plate 3 may have a second flanging 31 extending upward. The second flanging 31 can block the oil at the edge of the partition plate 3, making it difficult for the oil at the edge of the partition plate 3 to flow outside the partition plate 3.

[0167] In some possible implementation manners of the embodiments of the present application, the sealing plate 6 is located within the second flanging 31, so that the oil flowing down along the sealing plate 6 can be received by the partition plate 3, reducing the possibility of the oil on the sealing plate 6 flowing outside the partition plate 3.

[0168] The sealing plate 6 is located within the second flanging 31, and at least part of the inner wall at the bottom of the main box body 4 is located inside the sealing plate 6. Therefore, the main box body 4 inside the sealing plate 6 is also located on the partition plate 3 within the second flanging 31. In this way, the oil flowing down along the inner wall of the main box body 4 is received by the partition plate 3, and the oil on the partition plate 3 is not easily flowed outside the partition plate 3 due to the blocking of the second flanging 31, reducing the possibility of the oil flowing down along the inner wall of the main box body 4 flowing onto the top surface of the housing 1.

[0169] In some possible implementation manners of the embodiments of the present application, the bottom of the sealing plate 6 may have a third flanging 61. The third flanging 61 extends towards the second flanging 31 and is connected to the partition plate 3 to fixedly connect the sealing plate 6 and the partition plate 3.

[0170] In some possible implementation manners of the embodiments of the present application, a third connection hole 612 may be formed on the third flanging 61. A fourth connection hole 321 may be formed at a position corresponding to the third flanging 61 on the partition plate 3. The fourth connection hole 321 corresponds to the third connection hole 612, and a second fastener 613 is inserted into the third connection hole 612 and the fourth connection hole 321 to fixedly connect the third flanging 61 and the partition plate 3.

[0171] The second fastener 613 may be a fastening bolt or other components that can be inserted into the third connection hole 612 and the fourth connection hole 321 to fix the third flanging 61 and the partition plate 3.

[0172] In some possible implementation manners of the embodiments of the present application, the third flanging 61 may be formed with a second boss 611 protruding upward, and the third connection hole 612 may be formed at the top of the second boss 611.

[0173] The partition plate 3 can be configured with a third convex platform 32 protruding upward. The third convex platform 32 is received in the space enclosed by the bottom of the second convex platform 611, and the fourth connection hole 321 can be configured at the top of the third convex platform 32.

[0174] The third convex platform 32 protrudes from the partition plate 3, such that the height of the fourth connection hole 321 is higher than the upper plate surface of the partition plate 3. In this way, the oil fluid on the plate surface of the partition plate 3 is not likely to flow into the fourth connection hole 321, and thus is not likely to leak out from the fourth connection hole 321 and the third connection hole 612 to the top of the third flange 61, reducing the oil fluid accumulation at the top of the third flange 61 and reducing the possibility of the oil fluid flowing from the top of the third flange 61 to the top surface of the top plate 224.

[0175] In some possible implementation manners of the embodiments of the present application, the end of the third flange 61 may have a fourth flange 62 extending upward. The fourth flange 62 is located within the second flange 31, that is, the fourth flange 62 is located above the partition plate 3 and does not protrude beyond the partition plate 3.

[0176] The fourth flange 62 can block the oil fluid flowing out between the third flange 61 and the partition plate 3, making it difficult for the oil fluid to flow to the top surface of the third flange 61, and reducing the possibility of the oil fluid flowing from the top of the third flange 61 to the top surface of the top plate 224.

[0177] In some possible implementation manners of the embodiments of the present application, referring to Figure 19 and Figure 20 , a first convex boss 44 may be provided on the inner wall of the main box body 4 corresponding to the sealing plate 6. The first convex boss 44 protrudes from the inner wall of the main box body 4, and the first convex boss 44 may be configured with a fifth connection hole 45. The fifth connection hole 45 penetrates through the first convex boss 44 and the inner wall of the main box body 4.

[0178] Referring to Figure 20 and Figure 21 , the sealing plate 6 is provided with a sixth connection hole 63 corresponding to the fifth connection hole 45. A third fastener 631 may be inserted into the fifth connection hole 45 and the sixth connection hole 63, and the third fastener 631 fixedly connects the sealing plate 6 and the main box body 4.

[0179] The first convex boss 44 protrudes from the inner wall of the main box body 4. In this way, the first convex boss 44 can block the oil fluid flowing along the inner wall of the main box body 4. When the oil fluid on the inner wall of the main box body 4 flows along the inner wall of the main box body 4, it is not likely to flow to the end of the first convex boss 44 away from the inner wall of the main box body 4. Therefore, the difficulty for the oil fluid to flow into the fifth connection hole 45 is increased, making it not likely for the oil fluid to flow into the fifth connection hole 45, and further making it not likely for the oil fluid to flow to the outside of the sealing plate 6 through the fifth connection hole 45 and the sixth connection hole 63, reducing the possibility of the oil fluid flowing from the sealing plate 6 to the top surface of the top plate 224.

[0180] In some possible implementation manners of the embodiments of the present application, with reference to Figure 17 , Figure 18 and Figure 20 , the main cabinet 4 may include an inner cabinet 46 and an outer cabinet 47 which are nested. A part of the sealing plate 6 is located between the inner cabinet 46 and the outer cabinet 47, and at least a part of the bottom of the inner cabinet 46 is located inside the sealing plate 6.

[0181] The inner wall of the main cabinet 4 in the embodiments of the present application is the inner wall of the inner cabinet 46.

[0182] The outer cabinet 47 is nested outside the inner cabinet 46 to shield the inner cabinet 46 and play a decorative role for the range hood.

[0183] In some possible implementation manners of the embodiments of the present application, with reference to Figure 15 and Figure 22 , a buffer member may be configured at the top of the partition plate 3. The buffer member may be a buffer belt 33. The buffer member protrudes from the partition plate 3, and the buffer member is spaced from the peripheral edge of the partition plate 3.

[0184] Since the buffer member protrudes from the partition plate 3, the resistance when the oil liquid on the partition plate 3 flows towards the oil fume port 15 can be increased, so that the flow rate of the oil liquid flowing from the partition plate 3 to the oil fume cavity 14 can be slowed down. In this way, the flow rate of the oil liquid on the partition plate 3 decreases when it flows to the edge of the oil fume port 15, so that the oil liquid can slowly flow down along the inner wall of the oil fume cavity 14, and the oil liquid is not likely to quickly rush into the oil fume cavity 14 from the edge of the partition plate 3, and thus is not likely to break away from the inner wall of the oil fume cavity 14 and drip onto the kitchen countertop from the smoke inlet 12.

[0185] The buffer member is spaced from the peripheral edge of the partition plate 3, so that the oil liquid can flow to the oil fume port 15 through the gap between the buffer member and the peripheral edge of the partition plate 3, reducing the amount of oil liquid remaining on the partition plate 3.

[0186] In some possible implementation manners of the embodiments of the present application, the buffer member may be a buffer belt 33. The two ends of the buffer belt 33 in the extending direction extend towards both sides of the partition plate 3 respectively. That is to say, one side of the buffer belt 33 faces the oil fume port 15, and the other side faces away from the oil fume port 15.

[0187] The side of the buffer belt 33 facing away from the oil fume port 15 can increase the resistance when the oil liquid flows towards the oil fume port 15, thus slowing down the flow rate of the oil liquid. The oil liquid blocked by the buffer belt 33 can flow to the edge of the oil fume port 15 through the gap between the two ends of the buffer belt 33 and the partition plate 3.

[0188] In some possible implementations of the present application, the buffer belt 33 may extend along a curve. For example, the buffer belt 33 may protrude in a direction away from the oil fume outlet 15, that is, the middle of the buffer belt 33 is farther away from the oil fume outlet 15 than the two ends. In this way, the buffer belt 33 can not only slow down the flow rate of the oil, but also guide the blocked oil, so that the oil gradually flows along the buffer belt 33 toward the two sides of the partition 3 and the oil fume outlet 15, thereby reducing the oil staying on the side of the buffer belt 33 away from the oil fume outlet 15.

[0189] In some possible implementations of the present application, the buffer belt 33 may extend along the fold line. For example, the buffer belt 33 may be in a "V" shape, and the middle of the buffer belt 33 is farther away from the oil fume outlet 15 than the two ends. The buffer belt 33 can not only slow down the flow rate of the oil, but also guide the blocked oil, so that the oil gradually flows along the buffer belt 33 toward the two sides of the partition 3 and the oil fume outlet 15, thereby reducing the oil from being retained on the side of the buffer belt 33 away from the oil fume outlet 15.

[0190] In some possible implementations of the embodiments of the present application, the buffer zone 33 may extend along a straight line to simplify the structure of the buffer zone 33 and facilitate the processing and manufacturing of the partition 3.

[0191] In some possible implementations of the embodiments of the present application, there can be multiple buffer zones 33, and the multiple buffer zones 33 can be spaced apart in a direction from the side away from the oil fume outlet 15 to the side close to the oil fume outlet 15. The multiple buffer zones 33 can improve the buffering effect on the oil flow rate, so that the oil can slowly flow downward along the edge of the partition 3 close to the oil fume outlet 15 to the inner wall of the oil fume chamber 14, and it is not easy for the oil to quickly gush out and drip from the smoke inlet 12.

[0192] In some possible implementations of the present application, reference is made to Figure 15 , Figure 18 , Figure 22 and Figure 23 The end of the partition 3 close to the oil fume outlet 15 has a fifth flange 34 extending downward, and a seventh connection hole 341 is configured on the fifth flange 34. Part of the housing 1 is attached to the side of the fifth flange 34 away from the oil fume outlet 15, and the housing 1 is configured with an eighth connection hole 111. The fifth flange 34 and the housing 1 are connected by a fourth fastener 35 penetrating through the seventh connection hole 341 and the eighth connection hole 111.

[0193] The top of the partition plate 3 can be configured with an oil baffle, and the oil baffle can be an oil baffle strip 36. The oil baffle is close to the fifth flanging 34. Both ends of the oil baffle along the extension direction of the fifth flanging 34 are located on both sides of the seventh connection hole 341, and there is a gap between the oil baffle and the seventh connection hole 341. In this way, the oil baffle can guide the oil liquid near the seventh connection hole 341 on the partition plate 3, so that the oil liquid flows along both ends of the oil baffle to both sides of the seventh connection hole 341, and it is not easy to flow into the seventh connection hole 341, and further it is not easy to flow out of the seventh connection hole 341 to the outside of the housing 1 or even drip onto the kitchen countertop.

[0194] In some possible implementation manners of the embodiments of the present application, the oil baffle can be an oil baffle strip 36. The oil baffle strip 36 protrudes from the partition plate 3. The oil baffle strip 36 can extend along a curve. The oil baffle strip 36 can protrude in a direction away from the oil fume port 15. Both ends of the extending direction of the oil baffle strip 36 extend to the fifth flanging 34, and the seventh connection hole 341 is located between both ends of the extending direction of the oil baffle strip 36.

[0195] The side of the oil baffle strip 36 facing away from the oil fume port 15 can guide the oil liquid, so that the oil liquid flows along the oil baffle strip 36 to both ends of the oil baffle strip 36, reducing the possibility of the oil liquid flowing into the seventh connection hole 341.

[0196] Both ends of the extending direction of the oil baffle strip 36 extend to the fifth flanging 34, so that there is no gap between both ends of the oil baffle strip 36 and the fifth flanging 34. In this way, the oil baffle strip 36 can directly guide the oil liquid to the fifth flanging 34, making it not easy for the oil liquid to flow to the side of the oil baffle strip 36 facing the oil fume port 15, thereby reducing the possibility of the oil liquid flowing into the seventh connection hole 341.

[0197] In some possible implementation manners of the embodiments of the present application, a second convex hull 342 can be provided on the side of the fifth flanging 34 facing the oil fume port 15, and the seventh connection hole 341 is configured on the second convex hull 342.

[0198] Since the second convex hull 342 protrudes from the fifth flanging 34, when the oil liquid on the surface of the fifth flanging 34 flows along the fifth flanging 34, it is not easy to flow to one end of the second convex hull 342 away from the fifth flanging 34. Therefore, the difficulty of the oil liquid flowing into the seventh connection hole 341 is increased, making it not easy for the oil liquid to flow into the seventh connection hole 341, and further making it not easy for the oil liquid to flow out of the seventh connection hole 341 to the outside of the housing 1 or even drip onto the kitchen countertop.

[0199] In some possible implementation manners of the embodiments of the present application, refer to Figure 18 、 Figure 22 and Figure 24, one end of the partition plate 3 facing away from the oil fume outlet 15 may have a sixth flanging 37, and the sixth flanging 37 extends upward. The sixth flanging 37 makes it difficult for the oil liquid to flow out from the side of the partition plate 3 facing away from the oil fume outlet 15, that is, it makes it difficult for the oil liquid to flow out from the front end of the partition plate 3.

[0200] A ninth connection hole 371 may be formed on the sixth flanging 37.

[0201] A part of the main box body 4 is attached to the side of the sixth flanging 37 facing the oil fume outlet 15. A third convex hull 410 may be provided on the side of the main box body 4 facing away from the sixth flanging 37. A tenth connection hole 48 is formed on the third convex hull 410. The tenth connection hole 48 corresponds to the ninth connection hole 371, and a fifth fastener 49 is inserted through the ninth connection hole 371 and the tenth connection hole 48.

[0202] Since the third convex hull 410 protrudes from the inner wall of the main box body 4, when the oil liquid on the inner wall of the main box body 4 flows along the inner wall of the main box body 4, it is not easy to flow to one end of the third convex hull 410 facing away from the sixth flanging 37. Therefore, the difficulty of the oil liquid flowing into the tenth connection hole 48 is increased, so that the oil liquid is not easy to flow into the tenth connection hole 48, and further the oil liquid is not easy to flow out of the tenth connection hole 48 to the outside of the main box body 4 or even drip onto the kitchen countertop.

[0203] In some possible implementation manners of the embodiment of the present application, referring to Figure 22 , the sixth flanging 37 may be connected to the second flanging 31 so that there is no gap between the sixth flanging 37 and the second flanging 31, thereby making it difficult for the oil liquid on the partition plate 3 to flow out from the edge of the partition plate 3.

[0204] In some possible implementation manners of the embodiment of the present application, referring to Figure 18 , the fan 5 has an air inlet 51 and an air outlet 52. The air inlet 51 faces the rear wall 41 of the main box body 4 and is spaced from the rear wall 41. The air outlet 52 extends to the top wall 42 of the main box body 4 and is communicated with the smoke outlet 43.

[0205] With such a setting, the distance between the air inlet 51 of the fan 5 and the oil fume outlet 15 is reduced. The fan 5 has side air inlet and top air outlet, reducing the smoke exhaust path of the fan 5 and improving the smoke exhaust efficiency of the range hood.

[0206] In some possible implementation manners of the embodiment of the present application, referring to Figure 1 , the housing 1 may have a first bracket 16, a second bracket 17 and two first side plates 18 arranged oppositely. The first bracket 16 is arranged on the top of the second bracket 17. The two first side plates 18 are located on both sides of the whole formed by the first bracket 16 and the second bracket 17. The first bracket 16, the second bracket 17 and the two first side plates 18 enclose a smoke collecting cavity 19.

[0207] The front end of the first side plate 18 has a folding edge extending in a direction away from the smoke collecting cavity 19, and the folding edge forms the smoke inlet side 11. The edge of one end of the smoke collecting cavity 19 close to the smoke inlet side 11 forms a smoke inlet 12, and the smoke inlet 12 is communicated with the smoke collecting cavity 19.

[0208] The range hood may further include an oil net 76, and the oil net 76 is detachably arranged on the first bracket 16.

[0209] Reference Figure 18 , the smoke collecting cavity 19 is communicated with the smoke cavity 14 through the oil net 76, and the oil net 76 can block oil liquid, impurities and the like in gases such as oil smoke flowing through the oil net 76.

[0210] Reference Figure 1 and Figure 2 , the oil net 76 is arranged on the first bracket 16, which can shorten the path between the oil net 76 and the smoke outlet 15, thereby improving the smoke exhaust efficiency of the range hood.

[0211] In some possible implementation manners of the embodiments of the present application, reference Figure 1 , the first bracket 16 may be inclined relative to the vertical direction. Exemplarily, the top end of the first bracket 16 may be farther away from the back plate 110 of the housing 1 than the bottom end of the first bracket 16. In this way, the first bracket 16 can guide the oil liquid attached to the inner wall of the first bracket 16, and the oil liquid attached to the side of the first bracket 16 facing the back plate 110 can flow downward along the inclined first bracket 16 and is finally collected in the oil cup 72.

[0212] Reference Figure 2 , the range hood may further include a lighting device 77, and the lighting device 77 is arranged on the first bracket 16. Since the top end of the first bracket 16 is inclined in a direction away from the back plate 110, arranging the lighting device 77 on the first bracket 16 can make the light emitting direction of the lighting device 77 inclined forward, which is convenient for the lighting device 77 to provide lighting for the cooker and kitchen utensils.

[0213] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
