Description

Technical Field

[0001] The utility model relates to the technical field of kitchen electrical appliances, in particular to a range hood. Background Art

[0002] The range hood is a common kitchen appliance. The range hood is usually divided into an open type and a hidden type. The smoke outlet of the open range hood is always open, while the hidden range hood is usually provided with a panel for covering the smoke outlet.

[0003] In the related art, a concealed range hood includes a smoke collecting hood, a panel and a driving device. The smoke collecting hood has a smoke collecting cavity and a smoke inlet connected to the smoke collecting cavity. The panel is located at the smoke inlet side of the smoke collecting hood and is rotatably connected to the smoke collecting hood. The driving device is arranged in the smoke collecting cavity and is bonded to the surface of the panel close to the smoke collecting cavity, and is used to drive the panel to rotate relative to the smoke collecting hood to open or close the smoke inlet.

[0004] However, the above range hood has the problem that the panel is easy to fall off during use. Utility Model Content

[0005] The present application provides a range hood, which is used to solve the problem that the range hood panel is easy to fall off.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, an embodiment of the present application provides a range hood, comprising a smoke hood, a panel, a mounting member, a transmission assembly and a drive motor. The smoke hood has a smoke collecting chamber, and a smoke inlet is provided on the smoke hood, and the smoke inlet is connected to the smoke collecting chamber. The panel is arranged on the outer side of the smoke hood. The panel is connected to the smoke hood and can rotate between a first position and a second position around a first axis relative to the smoke hood. When the panel is in the first position, the panel cover is arranged on the smoke inlet to close the smoke inlet. When the panel is in the second position, the panel is separated from the smoke inlet to open the smoke inlet. The mounting member is connected to the smoke hood. The transmission assembly is connected to the panel and is located on a side of the panel close to the smoke hood. The drive motor is connected to the mounting member, and the drive motor is connected to the panel through the transmission assembly, and is used to drive the panel to rotate relative to the smoke hood.

[0008] Wherein, a first limiting protrusion is provided on the mounting member, and the first limiting protrusion is used to stop the driving motor from rotating when the panel rotates from the second position to the first position.

[0009] It is understandable that, in the process of the driving motor driving the panel to rotate from the second position to the first position through the transmission assembly, when the panel rotates to the first position, the panel will cover the smoke inlet, and the driving motor will continue to rotate under the action of inertia, and then drive the panel to squeeze the smoke hood through the transmission assembly. In this case, the driving motor can provide a pulling force to the panel through the transmission assembly, and the smoke hood can provide a supporting force to the panel in the opposite direction of the above pulling force. Under the action of the above pulling force and supporting force, it is easy to cause the panel to fall off the smoke hood.

[0010] The present application sets a first limiting protrusion on the mounting member, and when the panel rotates to the first position, the transmission assembly abuts against the first limiting protrusion during the process of the driving motor driving the panel to rotate from the second position to the first position through the transmission assembly, so as to prevent the driving motor from continuing to rotate under the action of inertia. In this way, the pulling force provided by the driving motor to the panel through the transmission assembly can be reduced, and the supporting force provided by the smoke hood to the panel can also be reduced, thereby reducing the risk of the panel falling off.

[0011] In some embodiments, the driving motor has an output shaft. The transmission assembly includes an active member and a connecting member. The active member has a first end and a second end, and the first end is connected to the output shaft. When the panel rotates from the second position to the first position, the active member abuts against the first limit protrusion to stop the driving motor from rotating. The connecting member is connected to the second end and the panel. The connecting member can rotate around the second axis relative to the active member, and the connecting member can rotate around the third axis relative to the panel, and the second axis, the third axis and the axis of the output shaft are parallel.

[0012] In some embodiments, the transmission assembly further includes a bracket, the bracket is connected to the panel and the connecting member, and the connecting member can rotate around a third axis relative to the bracket.

[0013] In some embodiments, the bracket includes a fixing plate and a connecting plate. The fixing plate is arranged opposite to the panel and connected to the panel. The fixing plate is provided with at least one overflow hole, and the overflow hole penetrates the fixing plate along the arrangement direction of the fixing plate and the panel. The connecting plate is located on a side of the fixing plate away from the panel and connected to the fixing plate. The connecting member is connected to the connecting plate, and the connecting member can rotate relative to the connecting plate around a third axis.

[0014] In some embodiments, a second limiting protrusion is provided on the mounting member, and the second limiting protrusion is used to stop the driving motor from rotating when the panel rotates from the first position to the second position.

[0015] In some embodiments, the active member includes a main body and a limiting portion. The main body is connected to the output shaft. The limiting portion is connected to the main body. When the panel is in the second position, the limiting portion is located between the main body and the second limiting protrusion, and the limiting portion abuts against the second limiting protrusion to stop the driving motor from rotating.

[0016] In some embodiments, the smoke collecting hood further has an installation cavity, which is located at the periphery of the smoke collecting cavity. The installation member and the drive motor are arranged in the installation cavity. The smoke collecting hood is provided with an avoidance hole, and the connecting member passes through the avoidance hole and is connected to the panel.

[0017] In some embodiments, the mounting member includes a first sub-plate and a second sub-plate. The first sub-plate is connected to the smoke hood. The second sub-plate is connected to the first sub-plate. The second sub-plate is arranged opposite to the active member, and the first limiting protrusion and the second limiting protrusion are connected to the second sub-plate and are located between the second sub-plate and the active member. The second sub-plate is provided with an axial hole, and the output shaft is passed through the axial hole.

[0018] In some embodiments, the range hood further comprises an elastic member connected to one of the panel and the fume hood. When the panel is in the first position, the elastic member is located between the panel and the fume hood, and the elastic member abuts against the other of the panel and the fume hood.

[0019] In a second aspect, an embodiment of the present application provides a range hood, comprising a smoke collecting hood, a panel, a mounting member, a transmission assembly and a drive motor. The smoke collecting hood has a smoke collecting cavity, and a smoke inlet is arranged on the smoke collecting hood, and the smoke inlet is connected to the smoke collecting cavity.

[0020] The panel is arranged on the outer side of the smoke hood. The panel is connected to the smoke hood and can rotate relative to the smoke hood around a first axis between a first position and a second position. When the smoke hood is in the first position, the panel cover is arranged on the smoke inlet to close the smoke inlet. When the smoke hood is in the second position, the panel is separated from the smoke inlet to open the smoke inlet. The mounting member is connected to the smoke hood. The transmission assembly is connected to the panel and is located on a side of the panel close to the smoke hood.

DETAILED DESCRIPTION

[0041] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0042] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0043] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0044] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0047] The range hood is a common kitchen appliance. It uses a fan to exhaust harmful gases such as oil fume, smoke, steam, etc. generated in the kitchen to the outside, keeping the kitchen air fresh, preventing oil fume from depositing on the kitchen walls and furniture, and reducing the harm of oil fume to the human body and the environment.

[0048] At present, the smoke outlet of the range hood is generally divided into open and hidden types. Although the open range hood has a good effect of absorbing oil smoke, the smoke outlet is always open and unsightly. The hidden range hood requires an additional panel to cover the smoke outlet.

[0049] In the related art, a concealed range hood includes a smoke collecting hood, a panel and a driving device. The smoke collecting hood has a smoke collecting cavity and a smoke inlet connected to the smoke collecting cavity. The panel is located at the smoke inlet side of the smoke collecting hood and is rotatably connected to the smoke collecting hood. The driving device is arranged in the smoke collecting cavity and is bonded to the surface of the panel close to the smoke collecting cavity, and is used to drive the panel to rotate relative to the smoke collecting hood to open or close the smoke inlet.

[0050] However, the above range hood has the problem that the panel is easy to fall off during use.

[0051] Based on this, Figure 1 and Figure 2 As shown, Figure 1 This is one of the structural schematic diagrams of a range hood provided in an embodiment of the present application. Figure 2This is a second structural schematic diagram of a range hood provided in an embodiment of the present application. The present application provides a range hood 1000 , which includes a housing 10 and a fan 20 .

[0052] Specifically, the box body 10 has a receiving cavity 101, and is provided with an air inlet 102 and an air outlet 103 communicating with the receiving cavity 101. The box body 10 has a mounting surface 104, and the mounting surface 104 is used to be connected to a wall.

[0053] The fan 20 is disposed in the accommodating chamber 101 , and is used to drive air flow into the accommodating chamber 101 through the air inlet 102 and to be discharged through the air outlet 103 , thereby reducing indoor air pollution.

[0054] It should be noted that the type of the fan 20 may be a centrifugal fan, an axial flow fan or a mixed flow fan, which may be selected according to actual conditions, and the present application does not make any specific limitation thereto.

[0055] For example, the present application takes the example of the type of the fan 20 being a centrifugal fan for description.

[0056] Among them, Figure 3 As shown, Figure 3 The third structural diagram of a range hood provided in an embodiment of the present application. The fan 20 includes a fan motor 201 and an impeller 202. The fan motor 201 can drive the impeller 202 to rotate, and can discharge the air in the box 10 out of the box 10, thereby generating a negative pressure area in the box 10.

[0057] In order to accommodate the oil smoke that cannot be discharged in time, Figure 1 and Figure 2 As shown, the range hood 1000 may further include a fume collecting hood 30 .

[0058] Specifically, Figure 4 As shown, Figure 4 The fourth structural diagram of a range hood provided in an embodiment of the present application is that the smoke collecting hood 30 is arranged at the lower side of the housing 10 and connected to the housing 10. The smoke collecting hood 30 has a smoke collecting cavity 302, and a smoke inlet 301 is arranged on the smoke collecting hood 30, and the smoke inlet 301 is connected to the smoke collecting cavity 302.

[0059] In this way, the oil smoke can enter the smoke collecting cavity 302 of the smoke collecting hood 30 through the smoke inlet 301 of the smoke collecting hood 30, thereby reducing the phenomenon of oil smoke overflowing and spreading.

[0060] In some embodiments, Figure 4As shown, the range hood 1000 may further include a panel 40, which is disposed outside the fume hood 30. The panel 40 is connected to the fume hood 30 and can rotate relative to the fume hood 30 around the first axis F1 between a first position and a second position. Figure 5 As shown, Figure 5 FIG5 is a structural diagram of a range hood provided by an embodiment of the present application. When the panel 40 is in the first position, the panel 40 covers the smoke inlet 301 to close the smoke inlet 301. Figure 6 As shown, Figure 6 This is a sixth structural schematic diagram of a range hood provided in an embodiment of the present application. When the panel 40 is in the second position, the panel 40 is separated from the smoke inlet 301 to open the smoke inlet 301.

[0061] It should be noted that the panel 40 and the smoke collecting hood 30 may be connected by a hinge, so as to realize the rotation of the panel 40 relative to the smoke collecting hood 30 around the first axis F1, and the first axis F1 is the axis center line of the hinge.

[0062] It is understandable that when the range hood 1000 is working, the fan motor 201 drives the impeller 202 to rotate, so that the impeller 202 can discharge the air in the frame to the outside through the smoke outlet assembly, thereby generating a negative pressure area in the box 10. At the same time, the panel 40 is located in the second position, the panel 40 is separated from the smoke inlet 301, and the smoke inlet 301 is opened. The rising oil smoke can enter the smoke collecting chamber 302 through the smoke inlet 301 of the smoke collecting hood 30 under the attraction of the negative pressure area. Then, the oil smoke is separated from the oil and gas under the centrifugal action of the impeller 202. The grease particles in the oil smoke are thrown to the inner wall of the oil smoke channel with the help of centrifugal force, condensed into oil droplets and collected through the oil path. The purified smoke is accelerated by the impeller 202 and discharged to the outside.

[0063] When the range hood 1000 stops working, the motor and the impeller stop working, and at the same time, the panel 40 is located at the first position, the panel 40 covers the smoke inlet 301, and the smoke inlet 301 is closed.

[0064] It should be noted that the material of the panel 40 can be glass, plastic or metal, which can be selected according to actual conditions, and this application does not make any specific restrictions on this.

[0065] In some embodiments, Figure 7 As shown, Figure 7 This is the seventh structural schematic diagram of a range hood provided in an embodiment of the present application. The range hood 1000 may further include a drive motor 60 , and the drive motor 60 is used to drive the panel 40 to rotate relative to the smoke collecting hood 30 .

[0066] It should be noted that the driving motor 60 has an output shaft 601 , and the driving motor 60 performs work externally through the output shaft 601 .

[0067] In some embodiments, Figure 7 As shown, the range hood 1000 may further include a transmission assembly 50.

[0068] It should be noted that the driving motor 60 may be connected to the panel 40 via the transmission assembly 50 , or may be directly connected to the panel 40 .

[0069] For example, Figure 7 As shown, the present application is described by taking the example that the driving motor 60 is connected to the panel 40 through the transmission assembly 50 .

[0070] It is understandable that the transmission assembly 50 is connected to the panel 40 and is located on a side of the panel 40 close to the smoke collecting hood 30. The driving motor 60 drives the transmission assembly 50 to rotate, thereby driving the panel 40 to rotate relative to the smoke collecting hood 30 around the first axis F1.

[0071] It should be noted that the rotation angle of the panel 40 relative to the smoke collecting hood 30 can reach 50°, which can improve the smoke extraction effect of the range hood 1000.

[0072] It should be noted that the transmission assembly 50 can be connected to the panel 40 by screws or the like, or can be glued to the panel 40 by glue. The specific selection can be made according to the actual situation, and this application does not make any specific limitation on this.

[0073] Exemplarily, the present application takes the bonding between the transmission assembly 50 and the panel 40 as an example for explanation.

[0074] It should be noted that the adhesive used to bond the transmission assembly 50 to the panel 40 is silicone adhesive, and may also be polyurethane sealant. This application does not limit this, and it is specifically set according to actual needs.

[0075] It should be noted that the number of the transmission assembly 50 can be one or more, which is not limited in the present application and can be set according to actual needs.

[0076] Exemplarily, the number of transmission components 50 is set to one, which can reduce costs.

[0077] Exemplarily, the number of transmission components 50 is set to be multiple, so that when a problem occurs in one transmission component 50, other transmission components 50 can continue to work and will not affect the use of the range hood 1000.

[0078] In some embodiments, Figure 8 As shown, Figure 8This is one of the structural schematic diagrams of a mounting plate and a transmission assembly provided in an embodiment of the present application. The transmission assembly 50 may include an active component 501 . The active component 501 has a first end 5011 and a second end 5012 . The first end 5011 is connected to the output shaft 601 .

[0079] It is understandable that the active member 501 can rotate around the output shaft 601. When the range hood 1000 is in operation, the drive motor 60 drives the output shaft 601 to rotate, and then the output shaft 601 drives the active member 501 to rotate.

[0080] Exemplarily, the output shaft 601 is provided with threads, and the first end 5011 of the active member 501 is connected to the output shaft 601 via a nut. The active rod can rotate around the output shaft 601.

[0081] In some embodiments, Fig. 9 As shown, Fig. 9 This is a second structural schematic diagram of a mounting plate and a transmission assembly provided in an embodiment of the present application. The active component 501 may include a main body 5013 , and the main body 5013 is connected to the output shaft 601 .

[0082] The active member 501 may include a limiting portion 5014. The limiting portion 5014 is connected to the main body 5013. In this way, the rotation of the main body 5013 can drive the limiting portion 5014 to rotate.

[0083] In some embodiments, the transmission assembly 50 may further include a connecting member 502 .

[0084] The connecting member 502 can be connected to the second end 5012 and the panel 40. The connecting member 502 can rotate relative to the active member 501 around the second axis F2 and the panel 40 around the third axis. The second axis F2 and the third axis F3 are parallel to the axis of the output shaft 601.

[0085] It should be noted that the connecting member 502 can be connected to the active member 501 and the panel 40 by rivets or nuts, etc. This application does not make specific restrictions on this, and it is specifically set according to actual conditions.

[0086] For example, the connecting member 502 and the active member 501 may be connected by a rivet, and the connecting member 502 may rotate around the second axis F2 relative to the active member 501. The second axis F2 is the central axis of the rivet.

[0087] Exemplarily, the connecting member 502 and the panel 40 may be connected via a nut and a cap, and the connecting member 502 may rotate around the third axis F3 relative to the panel 40. The third axis F3 is the central axis of the nut.

[0088] It should be noted that the shape of the connecting member 502 can be a straight rod, or can be designed as a curved rod, etc. This application does not make any specific restrictions on this, and it is specifically configured according to actual conditions.

[0089] In some embodiments, Figure 7 and Fig.10 As shown, Fig.10 This is a structural schematic diagram of a bracket provided in an embodiment of the present application. The transmission assembly 50 may also include a bracket 503. The bracket 503 may be connected to the panel 40 and the connecting member 502. The connecting member 502 may rotate around a third axis F3 relative to the bracket 503.

[0090] It is understandable that the connection member 502 is connected to the panel 40 through the bracket 503, which can increase the contact area between the bracket 503 and the panel 40. This can make the connection between the transmission assembly 50 and the panel 40 more stable and more stable.

[0091] In some embodiments, Figure 7 and Fig.10 As shown, the bracket 503 may include a fixing plate 5031, which is arranged opposite to the panel 40 and connected to the panel 40. The fixing plate 5031 is provided with at least one glue overflow hole 5032, which penetrates the fixing plate 5031 along the arrangement direction of the fixing plate 5031 and the panel 40.

[0092] It can be understood that the bracket 503 is connected to the panel 40 by glue, and the provision of the glue overflow hole 5032 can reduce bubbles between the bracket 503 and the panel 40, thereby making the connection between the bracket 503 and the panel 40 more stable.

[0093] Exemplarily, the number of the glue overflow holes 5032 may be one, two, three, four, etc.

[0094] In some embodiments, the bracket 503 may include a connecting plate 5033 located on a side of the fixing plate 5031 away from the panel 40 and connected to the fixing plate 5031. The connecting member 502 is connected to the connecting plate 5033 and can rotate relative to the connecting plate 5033 around a third axis.

[0095] It can be understood that the connecting plate 5033 is movably connected to the connecting member 502 , and the connecting member 502 can rotate around the third axis relative to the connecting plate 5033 .

[0096] It should be noted that the connection plate 5033 and the connection member 502 may be connected by rivets or nuts, etc. This application does not make any specific limitation on this, and it is specifically configured according to actual conditions.

[0097] Exemplarily, the connecting members 502 may be connected to each other by nuts and caps, and the connecting members 502 may rotate around the third axis F3 relative to the panel 40. The third axis F3 is the central axis of the nut.

[0098] In some embodiments, Figure 7 and Fig.11 As shown, Fig.11 This is a schematic diagram of the structure of a mounting component provided in an embodiment of the present application. The range hood 1000 may further include a mounting component 70 , and the mounting component 70 is connected to the fume collecting hood 30 .

[0099] It should be noted that the drive motor 60 can be connected to the mounting member 70 and then fixed on the smoke collecting hood 30 , the drive motor 60 can also be directly fixed on the smoke collecting hood 30 , or the drive motor 60 can also be fixed outside the smoke collecting hood 30 .

[0100] For example, the present application takes the example of the driving motor 60 being connected to the mounting member 70 and then fixed on the smoke collecting hood 30. In this way, the driving motor 60 can be connected more firmly and the operation stability is better.

[0101] In some embodiments, Fig.11 and Fig.12 As shown, Fig.12 The third structural schematic diagram of a mounting plate and a transmission assembly provided in an embodiment of the present application, a first limit protrusion 701 may be provided on the mounting member 70, and the first limit protrusion 701 is used to stop the driving motor 60 from rotating when the panel 40 rotates from the second position to the first position.

[0102] It is understandable that, in the process of the driving motor 60 driving the panel 40 to rotate from the second position to the first position through the transmission assembly 50, when the panel 40 rotates to the first position, the panel 40 will cover the smoke inlet 301, and at this time, the driving motor 60 will continue to rotate under the action of inertia, and then drive the panel 40 to squeeze the smoke hood 30 through the transmission assembly 50. In this case, the driving motor 60 can provide a pulling force to the panel 40 through the transmission assembly 50, and the smoke hood 30 can provide a supporting force in the opposite direction of the above-mentioned pulling force to the panel 40. Under the action of the above-mentioned pulling force and supporting force, it is easy to cause the panel 40 to fall off from the smoke hood 30.

[0103] In this way, the present application sets the first limiting protrusion 701 on the mounting member 70, and when the driving motor 60 drives the panel 40 to rotate from the second position to the first position through the transmission assembly 50, when the panel 40 rotates to the first position, the transmission assembly 50 abuts against the first limiting protrusion 701, and the driving motor 60 can be prevented from continuing to rotate under the action of inertia. In this way, the pulling force provided by the driving motor 60 to the panel 40 through the transmission assembly 50 can be reduced, and the supporting force provided by the smoke hood 30 to the panel 40 can also be reduced, thereby reducing the risk of the panel 40 falling off.

[0104] Furthermore, when the panel 40 rotates from the second position to the first position, the active member 501 of the transmission assembly 50 abuts against the first limiting protrusion 701 of the mounting member 70 to stop the driving motor 60 from rotating.

[0105] In some embodiments, Fig.11 and Fig.13 As shown, Fig.13 The fourth structural diagram of a mounting plate and a transmission assembly provided in an embodiment of the present application, the mounting member 70 may be provided with a second limiting protrusion 702. The second limiting protrusion 702 is used to stop the driving motor 60 from rotating when the panel 40 rotates from the first position to the second position.

[0106] In this way, when the panel 40 is in the second position, the transmission assembly 50 can be restricted by the second limiting protrusion 702, thereby limiting the maximum opening angle of the panel 40, thereby reducing the problem of poor efficiency and effect of gathering oil smoke caused by the panel 40 flipping too large an angle.

[0107] It is understandable that when the panel 40 is located at the second position, the limiting portion 5014 of the active member 501 is located between the main body 5013 and the second limiting protrusion 702, and the limiting portion 5014 abuts against the second limiting protrusion 702 to stop the driving motor 60 from rotating.

[0108] In this way, the abutment area can be increased by the abutment between the limiting portion 5014 and the second limiting protrusion 702, so that the abutment between the active member 501 and the second limiting protrusion 702 is more stable and more stable.

[0109] It should be noted that the first limiting protrusion 701 and the second limiting protrusion 702 can be integrally formed with the mounting member 70, which is convenient for production and processing.

[0110] In some embodiments, Fig.11 As shown, the mounting member 70 may include a first sub-plate 703 , and the first sub-plate 703 is connected to the smoke collecting hood 30 .

[0111] Exemplarily, three connection holes are provided on the first sub-plate 703, and the first sub-plate is connected to the smoke collecting hood 30 by screws or screws passing through the connection holes. The three connection holes can be arranged in a triangle, so that the installation of the first sub-plate 703 can be more reliable.

[0112] It is understandable that the first sub-board 703 and the smoke hood 30 are arranged relative to each other, and the connection between the first sub-board 703 and the smoke hood 30 can increase the connection area between the mounting member 70 and the smoke hood 30, thereby making the mounting member 70 more firmly installed and more reliable.

[0113] In some embodiments, the mounting member 70 may include a second sub-plate 704 connected to the first sub-plate 703. The first limiting protrusion 701 and the second limiting protrusion 702 are connected to the second sub-plate 704 and are located between the second sub-plate 704 and the active member 501.

[0114] In this way, the transmission assembly 50 can rotate between the first limiting protrusion 701 and the second limiting protrusion 702 .

[0115] The driving motor 60 is connected to the second sub-plate 704 of the mounting member 70. The second sub-plate 704 is provided with an axial hole 705, and the output shaft 601 is passed through the axial hole 705. The driving motor 60 performs work externally through the output shaft 601.

[0116] It can be understood that in order to make the second axis and the third axis parallel to the axis of the output shaft 601 , the second sub-plate 704 and the active member 501 are arranged opposite to each other.

[0117] In some embodiments, Fig.14 As shown, Fig.14 The eighth structural diagram of a range hood provided in the embodiment of the present application is that the smoke collecting hood 30 further has an installation cavity 303 , which is located at the peripheral side of the smoke collecting cavity 302 . The mounting member 70 and the driving motor 60 are disposed in the installation cavity 303 .

[0118] It is understandable that the installation cavity 303 is not connected to the smoke collecting cavity 302. In this way, the drive motor 60 and the installation member 70 are arranged in the installation cavity 303, which can reduce the pollution by oil smoke, thereby reducing the accumulation of oil stains on the drive motor 60 and the installation member 70.

[0119] It should be noted that if Fig.15 As shown, Fig.15The ninth structural diagram of a range hood provided by the embodiment of the present application, since the mounting member 70 and the driving motor 60 are arranged in the mounting cavity 303, in order to enable the connecting member 502 to work normally, an avoidance hole 304 is also provided on the smoke collecting hood 30, and the connecting member 502 can pass through the avoidance hole 304 to connect with the panel 40. In this way, the connecting member 502 does not interfere with the smoke collecting hood 30 during the movement.

[0120] In some embodiments, the range hood 1000 further includes an elastic member 80 connected to one of the panel 40 and the fume hood 30. When the panel 40 is located at the first position, the elastic member 80 is located between the panel 40 and the fume hood 30, and the elastic member 80 abuts against the other of the panel 40 and the fume hood 30.

[0121] For example, Fig.15 and Fig.16 As shown, Fig.16 for Fig.15 In the partial enlarged schematic diagram at A, the elastic member 80 is connected to the smoke collecting hood 30. When the panel 40 is located at the first position, the elastic member 80 is located between the panel 40 and the smoke collecting hood 30, and the elastic member 80 abuts against the panel 40.

[0122] In this way, when the transmission assembly 50 drives the panel 40 to close the smoke inlet 301, the panel 40 is in contact with the smoke hood 30 and is in a stationary position. The opening and closing panel 40 is still subject to the pulling force of the transmission assembly 50 and the gravity of the panel 40 itself. At this time, the elastic member 80 is in contact with the smoke hood 30, and after receiving the support force provided by the smoke hood 30, it provides a reverse force for the panel 40, which can balance or reduce the combined force of the pulling force and gravity on the panel 40, thereby reducing the force on the bonding surface between the panel 40 and the transmission assembly 50, and reducing the risk of the panel 40 falling off after the bonding surface between the panel 40 and the transmission assembly 50 is detached.

[0123] It should be noted that the material of the elastic member 80 can be sponge, rubber, silicone, etc. This application does not make any specific limitation on this, and it is specifically configured according to actual conditions.
