Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and in particular to a smoke collecting mechanism and a range hood. Background Art

[0002] With the improvement of people's living standards, range hoods that can extract oil smoke have become one of the indispensable kitchen appliances in people's daily lives. In order to reduce the space occupied by the range hood in the kitchen, requirements are put forward for the thinner and lighter settings of the range hood.

[0003] The prior art provides a range hood, which includes a smoke collecting hood and a bellows arranged on the top of the smoke collecting hood, a fan is arranged inside the bellows, the smoke collecting hood is arranged in a "7" shape, and the front side surface of the main part is arranged nearly vertically; a smoke collecting port is opened on the front side of the smoke collecting hood, and a smoke collecting plate is rotatably installed on the front side of the smoke collecting hood, a push rod motor is arranged inside, the fixed part of the push rod motor is installed on the smoke collecting hood and the push rod is connected to the smoke collecting plate, and the extension and retraction of the push rod relative to the fixed part drives the smoke collecting plate to flip and open or close the smoke collecting port.

[0004] The range hood provided by the prior art reduces the thickness of the main part of the smoke collecting hood by setting the smoke collecting hood in a "7" shape, and assists the smoke collecting plate to ensure the smoke collecting effect when the range hood is in operation; however, since the smoke collecting plate is driven to open or close by a push rod motor, and the size of the smoke collecting hood is effective in the front-to-back direction, the size of the push rod motor is greatly restricted, so that the extension stroke of the push rod of the push rod motor is greatly restricted, and the angle of the smoke collecting plate when flipped open is smaller, which affects the user experience of the range hood and is not conducive to the further lightweight setting of the range hood.

[0071] Embodiment 1

[0072] The present embodiment provides a range hood, which can improve the fume extraction effect and enhance the user experience of the range hood while achieving the lightness and thinness of the range hood.

[0073] like Figures 1 to 5 As shown, the range hood includes a smoke collecting device 100 and a bellows assembly 200. The smoke collecting device 100 has a smoke collecting chamber 63 and a smoke inlet 211 connected to the smoke collecting chamber 63, and the top of the smoke collecting device 100 has a smoke outlet connected to the smoke collecting chamber 63; the bellows assembly 200 is installed at the top of the smoke collecting device 100, and the bellows assembly 200 includes a bellows and a fan installed inside the bellows, the air inlet of the fan is connected to the smoke outlet, and the air outlet of the fan is installed with a check valve, and the air outlet end of the check valve is connected to a smoke exhaust pipe, and the smoke exhaust pipe extends out of the bellows to exhaust the oil smoke into the external environment.

[0074] The smoke collecting device 100 includes a housing component and a smoke collecting mechanism, wherein the housing component has a smoke collecting chamber 63, and the front side of the housing component is provided with a front opening connected to the smoke collecting chamber 63; the smoke collecting mechanism is rotatably installed on the front side of the housing component and has a smoke inlet 211 connected to the front opening, and the smoke collecting mechanism can open or close the front opening. When the front opening is opened and the fan is running, negative pressure is generated at the smoke inlet 211, and the oil smoke in the external environment enters the smoke collecting chamber 63 through the smoke inlet 211 due to the negative pressure, and enters the inside of the fan under the exhaust action of the fan and is discharged through the smoke exhaust pipe; when the smoke collecting mechanism closes the front opening, the smoke inlet 211 is closed at the same time, and the front side of the smoke collecting device 100 is roughly flush, so that the overall appearance of the smoke collecting device 100 and the range hood is simple and beautiful. That is, the smoke collecting mechanism has a closed state in which the front opening is closed and an open state in which the front opening is opened.

[0075] The housing assembly includes a smoke collecting hood 6, which has a smoke collecting vertical portion 61 and a smoke collecting horizontal portion 62 connected to the top of the smoke collecting vertical portion 61. The smoke collecting horizontal portion 62 extends forward from the top of the smoke collecting vertical portion 61, so that the smoke collecting hood 6 is in a "7" shape as a whole, thereby making the overall thickness of the housing assembly smaller, and the top has enough width to install the wind box. At the same time, the smoke collecting horizontal portion 62 can stop the oil smoke from escaping upwards, thereby improving the smoke collection effect. The front side opening is set at the front side of the smoke collecting vertical portion 61.

[0076] The casing assembly also includes a front panel 9 arranged on the front side of the smoke collecting hood 6, the front panel 9 is located above the front opening, and when the smoke collecting mechanism is in a closed state, the front side of the smoke collecting mechanism is located below the front panel 9, and the front side surface of the smoke collecting mechanism and the front side surface of the front panel 9 are arranged side by side and roughly flush.

[0077] In order to collect the oil in the smoke collecting chamber 63 , the range hood further comprises an oil cup 300 , which is mounted at the bottom of the smoke collecting hood 6 . An oil discharge port is provided at the bottom of the smoke collecting chamber 63 , and the oil discharge port is arranged opposite to the upper opening of the oil cup 300 .

[0078] It is worth noting that the structures of the oil cup 300 and the bellows assembly 200 can be set with reference to the prior art, which is not the focus of the present invention and will not be described in detail here.

[0079] In order to improve the smoke collecting effect of the smoke collecting mechanism, the smoke collecting mechanism includes a flap assembly 1 and a flip chamber assembly 2. The lower end of the flip chamber assembly 2 is movably installed in the smoke collecting chamber 63, and the upper part of the flip chamber assembly 2 can be flipped out of the front opening or flipped back into the smoke collecting chamber 63, and the flip chamber assembly 2 has a smoke inlet 211 that passes through the front and back; the flap assembly 1 is located at the front side of the flip chamber assembly 2, and the upper end of the flap assembly 1 is rotatably installed on the smoke collecting hood 6, and can open or close the front opening and the smoke inlet 211 at the same time.

[0080] When the flap assembly 1 is closed relative to the smoke hood 6, the smoke collecting mechanism is in a closed state, at which time the flip chamber assembly 2 is located inside the smoke collecting chamber 63, and the flap assembly 1 simultaneously closes the smoke inlet 211 and the front opening; when the flap assembly 1 is opened relative to the smoke hood 6, the smoke collecting mechanism is in an open state, the upper end of the flip chamber assembly 2 extends out of the front opening, and the flip chamber assembly 2 and the flap assembly 1 are combined to form a smoke collecting chamber with a lower opening, and the smoke collecting chamber is connected to the smoke collecting chamber 63 through the smoke inlet 211, so as to gather the smoke and guide the smoke into the smoke collecting chamber 63 through the smoke inlet 211, thereby improving the smoke collecting effect.

[0081] In this embodiment, the smoke collecting mechanism includes a driving motor 4, an output shaft 41 of the driving motor 4 is transmission-connected to one of the flap assembly 1 and the flip chamber assembly 2, and a motor housing 43 of the driving motor 4 is transmission-connected to the other of the flap assembly 1 and the flip chamber assembly 2, and the driving motor 4 drives the flap assembly 1 and the flip chamber assembly 2 to move in conjunction with the flap assembly 1.

[0082] The smoke collecting mechanism and range hood provided in the present embodiment are provided with a flip chamber assembly 2 and a flap assembly 1. When the flap assembly 1 opens the smoke inlet 211, the flip chamber assembly 2 and the flap assembly 1 can cooperate to form a smoke collecting chamber to increase the smoke collecting area, thereby improving the smoke collecting effect. At the same time, since the flap assembly 1 and the flip chamber assembly 2 are driven by the drive motor 4 and are arranged in linkage, the flap assembly 1 and the flip chamber assembly 2 share a driving structure, which simplifies the cost of the smoke collecting mechanism and reduces the space occupied by the driving structure. Furthermore, since the driving motor 4 moves with the flap assembly 1, it can increase the opening stroke of the flap assembly 1 while reducing the space required for the activity of the driving motor 4, thereby reducing the overall space occupied by the smoke collecting mechanism, which is conducive to realizing the lightweight setting of the smoke collecting device 100 and the range hood.

[0083] like Figure 3 and Figure 4 As shown, in order to improve the smoke collecting and smoke diversion effects when the flap assembly 1 is opened, the flap assembly 1 includes a smoke collecting plate 11 and a smoke guiding boss 12 protruding from the rear side of the smoke collecting plate 11, the smoke guiding boss 12 extends in the left and right directions, and a smoke guiding surface is formed on the side of the smoke guiding boss 12 away from the smoke collecting plate 11. When the flap assembly 1 is in a closed state, the smoke collecting plate 11 closes the smoke inlet 211, and the smoke guiding boss 12 is located in the smoke inlet 211 of the flip chamber assembly 2 to avoid interference between the smoke guiding boss 12 and the flip chamber assembly 2, and to avoid the smoke guiding boss 12 occupying additional space in the smoke collecting chamber 63; when the flap assembly 1 is in an open state, the upper end of the smoke guiding boss 12 is close to the upper side of the smoke inlet 211, and the smoke guiding surface of the smoke guiding boss 12 guides the oil smoke to flow toward the smoke inlet 211 to improve the smoke collecting and oil guiding effects; at the same time, the setting of the smoke guiding boss 12 can reduce the probability of the oil smoke escaping upward through the gap between the upper end of the flip chamber assembly 2 and the smoke collecting plate 11, thereby further improving the smoke collecting effect.

[0084] In this embodiment, the smoke guide surface is a plane to reduce the difficulty of processing. The distance between the smoke guide surface and the back side of the smoke collecting plate 11 gradually increases from bottom to top. When the flap assembly 1 opens the smoke inlet 211, the smoke guide surface is tilted backward from bottom to top to facilitate guiding the upward-flowing smoke to flow into the smoke inlet 211. Further, when the smoke collecting mechanism is in a fully open state, the angle between the smoke guide surface and the horizontal plane is 30° to 60°. In other embodiments, the smoke guide surface can be a circular arc surface that is concave forward, or the smoke guide surface can be a smooth curved surface with a convex lower end and a concave upper end.

[0085] When the smoke collecting mechanism is in the closed state, the upper end of the smoke guiding boss 12 is spaced apart from the upper side of the smoke inlet 211 to prevent the flap assembly 1 from flipping outward relative to the flip chamber assembly 2 and causing interference between the smoke guiding boss 12 and the flip chamber assembly 2 .

[0086] The flip chamber assembly 2 at least includes two smoke-collecting side parts that are opposite to each other and spaced apart in the left-right direction and a smoke-collecting top part connected between the top ends of the two smoke-collecting side parts. The smoke-collecting top part and the two smoke-collecting side parts together form a smoke inlet 211. The lower end of the smoke-collecting side part is located in the smoke collecting chamber 63 and is movably connected to the smoke collecting cover 6. The smoke-collecting side part and the smoke-collecting top part both extend a certain width in the front-back direction to guide the oil smoke from the smoke inlet 211 into the smoke collecting chamber 63. That is, when the smoke-collecting mechanism is in a fully opened state, the rear ends of the smoke-collecting side part and the smoke-collecting top part are both located in the smoke collecting chamber 63.

[0087] like Figures 5 to 10As shown, in this embodiment, the output shaft 41 of the driving motor 4 is in transmission connection with the flap assembly 1, and the motor housing 43 of the driving motor 4 is hinged with the flip chamber assembly 2, thereby facilitating the driving force of the driving motor 4 to directly overcome the gravity of the flip chamber assembly 1 and drive the flip chamber assembly 1 to rotate, and the flip chamber assembly 2 can be flipped with the assistance of gravity, saving the driving force of the driving motor 4 and facilitating the control of the driving stroke of the flip chamber assembly 1. In other embodiments, the driving motor 4 may also be connected to the flap assembly 1 through the motor housing 43, and the output shaft 41 of the driving motor 4 is connected to the flip chamber assembly 2.

[0088] In order to better realize the linkage drive of the flap assembly 1 and the flip chamber assembly 2 by the driving motor 4, the smoke collecting mechanism also includes a flip linkage assembly 3, which is connected between the flap assembly 1 and the flip chamber assembly 2, and the driving motor 4 is installed on the flip linkage assembly 3, and the driving motor 4 drives the flap assembly 1 and the flip chamber assembly 2 to be linked through the flip linkage assembly 3.

[0089] In this embodiment, the flip linkage assembly 3 includes a mounting rod 31 and a transmission rod group 32, the first end of the mounting rod 31 is connected to the upper end of the flap assembly 1 and the second end is hinged to the smoke hood 6, the corresponding output shaft 41 or motor housing 43 is connected to the mounting rod 31; the transmission rod group 32 is connected between the flip chamber assembly 2 and the corresponding output shaft 41 or motor housing 43. Specifically, the output shaft 41 is connected to the mounting rod 31, and the motor housing 43 is hinged to the transmission rod group 32.

[0090] That is, in this embodiment, when the output shaft 41 of the driving motor 4 rotates, it drives the mounting rod 31 to rotate, thereby driving the flap assembly 1 to rotate relative to the smoke hood 6; since the output shaft 41 is connected to the mounting rod 31, the movement of the mounting rod 31 drives the driving motor 4 to move as a whole, so that the driving motor 4 drives the transmission rod group 32 to move, and then drives the upper end of the flip chamber assembly 2 to flip forward relative to the smoke hood 6, so that the driving motor 4 moves with the flap assembly 1, and the flip chamber assembly 2 and the flap assembly 1 are linked.

[0091] In other embodiments, the output shaft 41 is connected to the transmission rod group 32, and the motor housing 43 is hinged to the mounting rod 31, that is, the rotation of the output shaft 41 drives the upper end of the flip chamber assembly 2 to rotate, and at the same time drives the driving motor 4 to move as a whole; the overall movement of the driving motor 4 drives the flip plate assembly 1 to flip through the mounting rod 31.

[0092] By setting the mounting rod 31, the driving motor 4 can transmit the driving force to the flap assembly 1, and by setting the transmission rod group 32, the driving motor 4 and the flip chamber assembly 2 can be connected to each other. The relative position of the driving motor 4 relative to the rotation axis of the flap assembly 1 and the upper end of the flip chamber assembly 2 can be set, so that the driving motor 4 can achieve the linkage drive of the flap assembly 1 and the flip chamber assembly 2 with a smaller driving force, and the probability of interference between the flap assembly 1 and the flip chamber assembly 2 can also be reduced. In another embodiment, the motor housing 43 or the output shaft 41 of the driving motor 4 can be directly connected to the flap assembly 1 or the flip chamber assembly 2.

[0093] Specifically, the first end of the mounting rod 31 is fixedly connected to the back side of the flap assembly 1, and the second end of the mounting rod 31 is hinged to the inner side of the smoke hood 6. The mounting rod 31 is at least partially a bent rod structure bent inward and backward. The upper end edge of the front opening of the smoke hood 6 is located in the concave space of the arc structure, thereby facilitating the connection between the mounting rod 31 and the flap assembly 1 and the smoke hood 6.

[0094] In order to improve the connection convenience between the mounting rod 31 and the smoke collecting hood 6, a plate mounting seat 10 is installed on the front wall of the smoke collecting chamber 63. The plate mounting seat 10 includes a seat body 101 and a shaft body 102 protruding from one side of the seat body 101. The shaft body 102 extends in the left-right direction, and the second end of the mounting rod 31 is rotatably mounted on the shaft body 102. In order to improve the connection convenience between the mounting rod 31 and the flap assembly 1, a mounting support 13 is provided on the back side of the flap assembly 1, and the first end of the mounting rod 31 is mounted on the mounting support 13.

[0095] Specifically, the mounting bracket 13 includes a first plate portion and a second plate portion that are vertically connected, the first plate portion is attached to and fastened to the back side of the flap assembly 1, and the second plate portion is connected to the first end of the mounting rod 31. Preferably, the second plate portion is detachably connected to the second end of the mounting rod 31 by a fastening screw. Preferably, at least two fastening screws are spaced apart along the height direction of the flap assembly 1 to ensure the stability of the connection.

[0096] The mounting rod 31 includes a main rod 311 and a mounting plate 312. The main rod 311 is at least partially bent backward. The lower end of the main rod 311 is connected to the flap assembly 1 and the upper end is connected to the smoke hood 6. The mounting plate 312 is detachably connected to the main rod 311, and the output shaft 41 is connected to the mounting plate 312. By providing a detachably connected main rod 311 and mounting plate 312, it is convenient to set and adjust the connection position of the drive motor 4 on the mounting rod 31, improve the connection convenience and reliability of the mounting rod 31 and the drive motor 4, and at the same time, it can reduce the overall processing cost of the mounting rod 31 and simplify the structure. In other embodiments, the main rod 311 and the mounting plate 312 can also be integrally formed.

[0097] In order to improve the connection convenience between the main rod 311 and the flap assembly 1, the main rod 311 includes a bent rod portion 3111 and a fixed rod portion 3112. One end of the bent rod portion 3111 is connected to the hinge seat on the smoke hood 6, and the other end of the bent rod portion 3111 is connected to the fixed rod portion 3112. The fixed rod portion 3112 extends along the height direction of the flap assembly 1, and the fixed rod portion 3112 is connected to the plate mounting seat 10. In this way, the contact area between the main rod 311 and the mounting seat can be increased, and the connection stability between the main rod 311 and the flap assembly 1 can be improved. The bent rod portion 3111 can be, but is not limited to, an arc-shaped bent rod structure, a U-shaped bent rod, or a C-shaped bent rod structure.

[0098] In this embodiment, the mounting plate 312 is connected to the rearwardly bent portion of the mounting rod 31, thereby increasing the spacing between the axis of the output shaft 41 and the rotation axis of the flap assembly 1, which is beneficial for designing and controlling the installation position and rated driving force of the drive motor 4. That is, in the front-to-back direction, the output shaft 41 is spaced apart at the rear side of the first end of the main rod 311, and in the vertical direction, the output shaft 41 is located between the two ends of the main rod 311.

[0099] One end of the mounting plate 312 is connected to the main rod 311, and the other end of the mounting plate 312 extends backward. The output shaft 41 of the drive motor 4 is connected to the rear end of the mounting plate 312. This can reduce the size of the main rod 311 while further increasing the distance between the axis of the output shaft 41 and the rotation axis of the flap assembly 1 in the front-to-back direction, thereby reducing the interference between the drive motor 4 and the smoke hood 6 and improving the installation convenience of the drive motor 4.

[0100] Furthermore, the mounting plate 312 is a triangular structure, and one side of the triangular structure is connected to the main rod 311, and the opposite end of the triangular structure is connected to the output shaft 41. This can increase the connection area between the mounting plate 312 and the main rod 311 while reducing the size of the mounting plate 312, thereby reducing the space occupied by the flip linkage assembly 3 and reducing costs.

[0101] The main rod 311 is provided with a plurality of first mounting holes 3113 along its extension direction, and the mounting plate 312 is provided with a second mounting hole 3121. The second mounting hole 3121 can be aligned with any first mounting hole 3113, and the mounting plate 312 and the main rod 311 are fastened by penetrating the aligned first mounting holes 3113 and the second mounting holes 3121. Therefore, during the assembly and debugging of the smoke collecting device 100, the installation position of the mounting plate 312 on the main rod 311 can be adjusted, thereby regulating the position of the output shaft 41 of the drive motor 4 relative to the main rod 311, thereby better ensuring that the drive motor 4 can drive the flap assembly 1 to open to a suitable angle, thereby improving the reliability of the smoke collecting device 100 and the range hood, and reducing the processing and debugging costs of the smoke collecting mechanism.

[0102] Furthermore, a plurality of second mounting holes 3121 are provided, and the arrangement of the second mounting holes 3121 is the same as that of the first mounting holes 3113. The number of the second mounting holes 3121 is less than the number of the first mounting holes 3113, and the plurality of second mounting holes 3121 are aligned one by one with the plurality of first mounting holes 3113, thereby increasing the installation stability and reliability of the mounting plate 312 on the main rod 311.

[0103] There are two mounting plates 312 that are opposite to each other and spaced apart in the left-right direction, the main rod 311 is clamped between the two mounting plates 312, and the output shaft 41 passes through the two mounting plates 312, thereby increasing the local structural strength and rigidity of the mounting rod 31, ensuring the connection stability and reliability of the drive motor 4 on the mounting rod 31, reducing the probability of the mounting plate 312 being deformed by force, and improving the driving stability and reliability of the drive motor 4 on the flap assembly 1.

[0104] The transmission rod group 32 includes a first connecting rod 322 and a connecting shaft 321. The connecting shaft 321 extends in the left-right direction and is connected to the upper end of the flip chamber assembly 2. The first connecting rod 322 is connected between the connecting shaft 321 and the driving motor 4. Specifically, the first connecting rod 322 is hinged to the motor housing 43 of the driving motor 4. Therefore, when the driving motor 4 is opened forward along with the flap assembly 1, the driving motor 4 drives the connecting shaft 321 to move forward along with the operation of the flap assembly 1 through the first connecting rod 322, and drives the upper end of the flip chamber assembly 2 to move forward; when the flip chamber assembly 1 is flipped and closed, the driving motor 4 moves backward as a whole, and drives the connecting shaft 321 to move backward through the first connecting rod 322, thereby driving the upper end of the flip chamber assembly 2 to rotate backward to return to the initial position.

[0105] The driving motor 4 is higher than the upper end of the flip chamber assembly 2, and the upper end of the first connecting rod 322 is connected to the driving motor 4. The first connecting rod 322 extends downward from top to bottom and its front end is connected to the connecting shaft 321. When the output shaft 41 of the driving motor 4 rotates, the lower end of the main rod 311 flips forward under the driving action of the driving motor 4, and the driving motor 4 moves downward as a whole, thereby causing the upper end of the first connecting rod 322 to move downward, driving the lower end of the driving motor 4 to move forward, that is, driving the upper end of the flip chamber assembly 2 to move forward. When the output shaft 41 of the driving motor 4 rotates in the opposite direction, the output shaft 41 drives the lower end of the main rod 311 to move backward, thereby driving the flap assembly 1 to close; at the same time, the driving motor 4 is raised as a whole, causing the upper end of the first connecting rod 322 to rise, and the lower end of the first connecting rod 322 moves backward, thereby driving the connecting shaft 321 to move backward, prompting the upper end of the flip chamber assembly 2 to move backward and reset.

[0106] The structural setting of the first connecting rod 322 can further save the driving force of the driving motor 4, and when the flap assembly 1 is flipped open, the distance between the flip chamber assembly 2 and the upper end of the flap assembly 1 can be reduced, thereby improving the smoke collection effect. In other embodiments, the first connecting rod 322 can also be a bent rod structure or other rod-shaped structures.

[0107] In order to improve the connection convenience between the first connecting rod 322 and the driving motor 4, the motor housing 43 of the driving motor 4 is protruded with a convex shaft 42, and the upper end of the first connecting rod 322 is rotatably sleeved on the convex shaft 42. The convex shaft 42 and the output shaft 41 are respectively protruded on opposite sides of the motor housing 43 to improve the reliability of the transmission and reduce the probability of interference between the mounting rod 31 and the transmission rod group 32.

[0108] The axes of the convex shaft 42 and the output shaft 41 are parallel and spaced apart to avoid dead points during movement, thereby improving the driving reliability of the drive motor 4 on the flap assembly 1 and the flip chamber assembly 2. Furthermore, when the smoke collecting mechanism is in a closed state, in the front-to-back direction, the convex shaft 42 is located in front of the output shaft 41, and the first connecting rod 322 is located in front of the drive motor 4 as a whole.

[0109] In order to further improve the operational stability of the flip chamber assembly 2, the transmission rod group 32 also includes a second connecting rod 323, the lower end of the second connecting rod 323 is connected to the connecting shaft 321, and the upper end of the second connecting rod 323 is connected to the smoke hood 6. This arrangement enables the upper end of the flip chamber assembly 2 to be supported on the smoke hood 6 through the second connecting rod 323, avoiding the problem that the upper end of the flip chamber assembly 2 is only suspended and supported on the drive motor 4 through the first connecting rod 322, resulting in excessive force on the drive motor 4 and thus causing damage, thereby improving the setting stability and reliability of the flip chamber assembly 2, and also improving the service life of the drive motor 4. Specifically, the upper end of the second connecting rod 323 is hinged to the smoke hood 6, and the lower end is connected to the connecting shaft 321.

[0110] Furthermore, at least two second connecting rods 323 are arranged at intervals along the left-right direction to reduce the force of a single second connecting rod 323, further improving the movement stability and reliability of the flip chamber assembly 2. Furthermore, the second connecting rod 323 is located on a side of the first connecting rod 322 away from the mounting rod 31 to avoid interference between structures.

[0111] In this embodiment, a fixing seat 30 is installed on the inner side of the smoke hood 6, and the upper end of the second connecting rod 323 is installed on the fixing seat 30 by rotating from the hinge shaft, so that the second connecting rod 323 can rotate around the hinge shaft. Further, the fixing seat 30 is a U-shaped structure, the bottom of the U-shaped structure is connected to the smoke hood 6, and the two second connecting rods 323 are respectively connected to the two side parts of the U-shaped structure to improve the connection convenience between the fixing seat 30 and the second connecting rod 323.

[0112] The second connecting rod 323 is preferably a U-shaped structure with its opening facing forward, that is, the second connecting rod 323 includes a main rod portion, an upper curved rod portion connected to the upper end of the main rod portion, and a lower curved rod portion connected to the lower end of the main rod portion, the upper curved rod portion extends forward from bottom to top, and the front end is hinged to the fixing seat 30, and the lower curved rod portion extends forward from top to bottom and the front end is connected to the connecting shaft 321, thereby helping to avoid interference between the second connecting rod 323 and the smoke hood 6.

[0113] The connecting shaft 321 includes a main shaft portion and two limiting ends connected to both ends of the main shaft portion, and at least one limiting end portion is detachably connected to the main shaft portion. One end of the main shaft portion passes through the side wall of the smoke inlet 211 to extend out of the smoke inlet 211, and the limiting end portion at the corresponding end is restricted to pass through the mounting shaft hole 23. Specifically, the connecting shaft 321 passes through the smoke collecting side portion.

[0114] In this embodiment, in order to improve the installation reliability of the drive motor 4, the overall shape of the drive motor 4 is D-shaped, which is conducive to determining the initial installation position of the drive motor 4 through the plane of the D-shaped structure. In other embodiments, other types of fool-proof structures can be set on the drive motor 4 to ensure the installation accuracy of the drive motor 4.

[0115] Furthermore, a foolproof mark is provided on the mounting rod 31, and the foolproof mark is used to mark the initial installation position of the drive motor 4 to prevent the drive motor 4 from being installed incorrectly, thereby improving the reliability of the drive motor 4. In this embodiment, the foolproof mark is a D-shaped hole opened on the mounting plate 312. In other embodiments, the foolproof mark can also be a convex or groove structure, or a silk-screen indication structure.

[0116] In this embodiment, the flip linkage assembly 3 further includes a limit rod 33, the second end of which is connected to the connecting shaft 321, and the limit rod 33 limits the maximum flip angle of the flip chamber assembly 2. The hinge axis of the second end of the limit rod 33 is parallel to the hinge axis of the first end of the first connecting rod 322 and is arranged at an interval. When the driving motor 4 drives the connecting shaft 321 to move, the movement of the connecting shaft 321 drives the limit rod 33 to rotate relative to the mounting rod 31. Since the limit rod 33 is hinged to the mounting rod 31, the rotation stroke of the flip chamber assembly 2 is limited by the limit rod 33. Therefore, the setting of the limit rod 33 can limit the activity stroke of the flip chamber assembly 2, thereby limiting the maximum angle of the flap assembly 1 relative to the smoke hood 6.

[0117] When the flap assembly 1 closes the smoke inlet 211, in the front-to-back direction, the first end of the limit rod 33, the first end of the first connecting rod 322 and the output shaft 41 are sequentially arranged in intervals from front to back, thereby improving the reliability of linkage and limit. That is, when the flap assembly 1 closes the smoke inlet 211, in the front-to-back direction, the rotation axis of the flap assembly 1, the hinge axis of the limit rod 33 and the mounting rod 31, the first end of the first connecting rod 322 and the axis of the output shaft 41 are sequentially arranged in parallel and intervals from front to back.

[0118] Furthermore, in the vertical direction, the axis of the output shaft 41 is located between the two ends of the limit rod 33, thereby increasing the length of the limit rod 33 while keeping the relative position of the drive motor 4 of the connecting shaft 321 unchanged, thereby avoiding the problem of the limit rod 33 being too short and causing the maximum flip angle of the flip chamber assembly 2 to be smaller.

[0119] In this embodiment, a hinge hole is formed at the first end of the limiting rod 33, and the hinge hole can be aligned with a second mounting hole 3121, and the limiting rod 33 is hinged to a fastener that penetrates the aligned hinge hole, the second mounting hole 3121, and the first mounting hole 3113, thereby simplifying the hinge structure of the limiting rod 33 and the mounting rod 31, and improving the compactness of the structure. Further, three second mounting holes 3121 are provided, and the hinge holes are aligned with the second mounting hole 3121 located in the middle.

[0120] In this embodiment, the limiting rod 33 is preferably an arc-shaped structure with an opening facing forward, which is simple in structure and convenient to set. However, it can be understood that the shape of the limiting rod 33 can be specifically limited according to the maximum stroke required for the flap assembly 1 to open. Furthermore, one limiting rod 33 is provided on each of the left and right sides of the mounting rod 31 to ensure the limiting effect and limiting stability, and reduce the probability of the limiting rod 33 being damaged by force.

[0121] In this embodiment, a mounting shaft hole 23 is provided on the side of the flip chamber assembly 2, and the mounting shaft hole 23 at least partially extends along the height direction of the flip chamber assembly 2, and the connecting shaft 321 is slidably penetrated in the mounting shaft hole 23. That is, the connecting shaft 321 can slide along the mounting shaft hole 23, so that the connecting shaft 321 can be changed in the vertical direction relative to the upper end of the flip chamber assembly 2 while driving the flip chamber assembly 2 to flip forward and backward, thereby avoiding the problem that the lower end of the flip chamber assembly 2 needs to move forward and backward or vertically while the upper end of the flip chamber assembly 2 moves forward, and further the lower end of the flip chamber assembly 2 can be fixedly arranged in the front-to-back direction and the vertical direction relative to the smoke collecting hood 6, thereby simplifying the installation of the flip chamber assembly 2 on the smoke collecting hood 6.

[0122] In other embodiments, the connecting shaft 321 is directly rotated or fixedly installed on the upper end of the flip chamber assembly 2, and the lower end of the flip chamber assembly 2 can be slidably arranged in the smoke hood 6 along the vertical direction, so that the upper end of the flip chamber assembly 2 moves forward and downward while the lower end of the flip chamber assembly 2 moves upward.

[0123] In order to improve the operation stability and reliability of the flap assembly 1 and the flip chamber assembly 2, a flip linkage assembly 3 is provided on each of the left and right sides of the flip chamber assembly 2, a mounting rod 31 is provided on each of the left and right sides of the flap assembly 1, and a transmission rod group 32 is provided on each of the left and right sides of the flip chamber assembly 2. The drive motor 4 is connected between a mounting rod 31 and the transmission rod group 32 on the corresponding side, and the other mounting rod 31 and the transmission rod group 32 are linked and connected through a coupling structure 34. As a result, the left and right ends of the flap assembly 1 are supported on the smoke hood 6 through the mounting rod 31, and the left and right ends of the flip chamber assembly 2 are supported on the smoke hood 6 through the connecting shaft 321, thereby ensuring the setting stability of the flap assembly 1; furthermore, the other mounting rod 31 and the transmission rod group 32 are connected through the coupling structure 34, which can reduce the number of drive motors 4 and reduce the driving cost. In other embodiments, the mounting rods 31 and the transmission rod groups 32 in the two groups of flip linkage assemblies 3 can be connected through the drive motor 4.

[0124] In this embodiment, the connection structure 34 includes a connection plate 341 and a first shaft 342 and a second shaft 343 protruding from opposite sides of the connection plate 341, the first shaft 342 is connected to the mounting rod 31, and the second shaft 343 is hinged to the transmission rod group 32; the output shaft 41 is connected to the mounting rod 31, the first shaft 342 is coaxially arranged with the output shaft 41, and the second shaft 343 is coaxially arranged with the hinge axis of the motor housing 43. In this way, the two groups of flip linkage components 3 can be synchronized to ensure the stability of the left and right ends of the flip plate component 1 and the flip chamber component 2. The connection plate 341 can be a circular plate, an elliptical plate or other plate-like structure, as long as it can avoid interference with the limit rod 33.

[0125] like Figure 2 , Figure 6 and Fig.11As shown, a clearance opening is provided on the front side of the smoke collecting hood 6, and the clearance opening is arranged in a one-to-one correspondence with the flip linkage assembly 3, and the flip linkage assembly 3 is inserted into the clearance opening so that the flap assembly 1 can be flipped outward. In order to improve the structural aesthetics of the smoke collecting device 100 and the range hood, the smoke collecting device 100 also includes an oil shield 8, one end of the oil shield 8 is connected to the flap assembly 1 and the other end freely extends backward, the oil shield 8 has an oil shield cavity 82 with an opening facing upward, and the flip linkage assembly 3 is at least partially accommodated in the oil shield cavity 82, so that the oil shield 8 upwardly blocks the flip linkage assembly 3, and the oil shield 8 is inserted into the clearance opening. By setting the oil shield 8, the flip linkage assembly 3 can be shielded and protected. On the one hand, the overall appearance aesthetics of the smoke collecting device 100 and the range hood can be improved, and on the other hand, the influence of oil smoke on the flip linkage assembly 3 and the drive motor 4 can be reduced, the operating reliability of the flip linkage assembly 3 and the drive motor 4 can be improved, and the cleaning difficulty can be reduced. Specifically, the lower end of the mounting rod 31 , the lower end of the limiting rod 33 , the lower end of the first connecting rod 322 and part of the connecting shaft 321 are located in the oil blocking chamber 82 .

[0126] The connecting shaft 321 movably passes through the oil shield 8. Specifically, the oil shield 8 is provided with an avoidance slot 81 at least on one side facing the flip chamber assembly 2. The extension direction of the avoidance slot 81 is consistent with the movement trajectory of the connecting shaft 321. The connecting shaft 321 is movably arranged in the avoidance slot 81 to prevent the setting of the oil shield 8 from affecting the connection between the flip linkage assembly 3 and the flip chamber assembly 2. Further, the oil shield 8 is provided with avoidance slots 81 on both the left and right sides.

[0127] In order to further reduce the influence of oil smoke on the flip linkage assembly 3 and the driving motor 4, two side smoke baffles 7 are arranged inside the smoke collecting hood 6. The two side smoke baffles 7 are respectively located on the left and right sides of the smoke inlet 211 and extend in the front-to-back direction. In the left and right directions, the side smoke baffles 7 at least block the flip linkage assembly 3 located inside the smoke collecting chamber 63, thereby preventing the oil smoke entering from the smoke inlet 211 from flowing to the flip linkage assembly 3, thereby reducing the probability of the flip linkage assembly 3 being contaminated by oil smoke.

[0128] In this embodiment, the side smoke baffles 7 are installed inside the smoke hood 6, and the two side smoke baffles 7 are respectively located between the flip chamber assembly 2 and the corresponding flip linkage assembly 3, and the side smoke baffles 7 are provided with long avoidance holes for avoiding the connecting shaft 321, that is, the side smoke baffles 7 are fixedly arranged relative to the smoke hood 6. In other embodiments, the side smoke baffles 7 may be connected to the left and right sides of the flip chamber assembly 2, that is, the side smoke baffles 7 are installed on the flip chamber assembly 2 and move with the flip chamber assembly 2.

[0129] A bottom mounting seat 20 is installed at the bottom of the smoke collecting chamber 63 . One bottom mounting seat 20 is provided on each of the left and right sides of the flip chamber assembly 2 . Both sides of the lower end of the flip chamber assembly 2 are rotatably mounted on the two bottom mounting seats 20 .

[0130] like Figure 8 and Fig.12 As shown, in this embodiment, in order to improve the convenience of disassembly and assembly of the smoke collecting mechanism, an inspection port 64 is provided on the side of the smoke collecting hood 6, and the inspection port 64 is arranged opposite to the driving motor 4 and part of the flip linkage assembly 3, and the connecting shaft 321 is exposed through the inspection port 64. The smoke collecting device 100 also includes an inspection plate, which can be detachably mounted on the smoke collecting hood 6 to close the inspection port 64. Furthermore, the inspection port 64 and the inspection plate are provided on both the left and right sides of the smoke collecting hood 6 to inspect the linkage assembly of the smoke collecting plate 11 on the corresponding side.

[0131] By setting the inspection plate and the inspection opening 64, when it is necessary to disassemble the smoke collecting mechanism when the flap assembly 1 is in the closed state, first remove the inspection plate to expose the inspection opening 64, and then remove the oil shield 8; then remove the connection structure between the limit rod 33 and the mounting rod 31; thereafter, separate the mounting plate 312 from the main rod 311, so that the flap assembly 1 and the flip chamber assembly 2 can be separated, and then the flap assembly 1 can be flipped open, and then the flip chamber assembly 1 can be flipped outward to open, so as to achieve maintenance of the structure.

[0132] It is worth mentioning that when the flap assembly 1 is in an open state and the drive motor 4 or the flip linkage assembly 3 needs to be repaired, the oil shield 8 is first removed to expose the smoke collecting plate 11 linkage assembly, and then the connecting shaft 321 can be removed to separate the flip chamber assembly 2 and the flap assembly 1, and then the flip chamber assembly 2 and the flap assembly 1 can be repaired separately.

[0133] Embodiment 2

[0134] This embodiment provides a smoke collecting device 100 and a range hood, and the smoke collecting device 100 provided in this embodiment is a further improvement based on the smoke collecting device 100 in the first embodiment, and this embodiment will not repeat the same structure as the first embodiment.

[0135] like Figures 13 to 15 As shown, in this embodiment, the smoke collecting mechanism also includes an auxiliary linkage assembly 5, which is connected between the flap assembly 1 and the upper end of the flip chamber assembly 2. The auxiliary linkage assembly 5 is configured to drive the upper end of the flip chamber assembly 2 to approach the flap assembly 1 when the flap assembly 1 is flipped open.

[0136] In the smoke collecting mechanism and the range hood provided by the present embodiment, when the flap assembly 1 is flipped open, the outward flipping of the flap assembly 1 drives the flip chamber assembly 2 to rotate outward, so that the flap assembly 1 and the flip chamber assembly 2 are combined to form a smoke collecting chamber; at the same time, since the outward flipping of the flap assembly 1 can drive the upper end of the flip chamber assembly 2 closer to the flap assembly 1, the size of the smoke collecting chamber can be increased, thereby improving the smoke collecting effect of the smoke collecting chamber. Furthermore, this arrangement can reduce the size requirements of the smoke guide boss 12 on the back side of the smoke collecting plate 11 and the matching requirements of the smoke guide boss 12 and the flip chamber assembly 2 while enhancing the smoke collecting effect.

[0137] In order to improve the installation and activity convenience of the flip chamber assembly 2, the flip chamber assembly 2 includes an installation outer frame and a smoke collecting chamber 21 slidably arranged on the inner side of the installation outer frame. The smoke collecting chamber 21 can slide along the height direction of the installation outer frame. The driving motor 4 is transmission-connected to the installation outer frame. The lower end of the installation outer frame is used for rotational connection with the smoke collecting hood 6. The auxiliary linkage assembly 5 is connected to the smoke collecting chamber 21.

[0138] The structural setting of the above-mentioned flip chamber assembly 2 enables the left and right ends of the flip chamber assembly 2 to be rotatably connected to the smoke collecting hood 6 only, thereby improving the convenience of disassembly of the flip chamber assembly 2 on the smoke collecting hood 6; at the same time, the smoke collecting chamber 21 is slidably arranged inside the mounting outer frame, so that the smoke collecting chamber 21 and the mounting outer frame can be flipped outward as a whole, and the smoke collecting chamber 21 can slide in the height direction relative to the mounting outer frame to approach or move away from the smoke collecting plate 11, thereby realizing a certain degree of decoupling of sliding and rotating movements, thereby improving the operating reliability of the flip chamber assembly 2.

[0139] In this embodiment, the mounting frame includes two side slide rails 22 that are opposite and spaced apart, one side slide rail 22 is provided on each of the left and right sides of the smoke collecting chamber 21, and the lower end of the side slide rail 22 is rotatably connected to the smoke collecting hood 6, the extension direction of the side slide rail 22 is consistent with the height direction of the smoke collecting chamber 21, and the left and right sides of the smoke collecting chamber 21 are respectively slidably mounted on the two side slide rails 22. In this way, the structure of the flip chamber assembly 2 can be simplified and the weight of the flip chamber assembly 2 can be reduced.

[0140] Furthermore, a mounting shaft hole 23 is provided on the side slide rail 22 along its length direction, and the connecting shaft 321 is penetrated in the mounting shaft hole 23. Avoidance shaft holes 212 are provided on the left and right sides of the smoke collecting cavity 21, and the extension direction of the avoidance shaft hole 212 is consistent with the extension direction of the mounting shaft hole 23. The mounting shaft hole 23 and the avoidance shaft hole 212 are at least partially aligned, and the connecting shaft 321 is penetrated in the avoidance shaft hole 212. The setting of the avoidance shaft hole 212 can reduce the matching requirements between the flip chamber assembly 2 and the connecting shaft 321, and avoid interference between structures.

[0141] In this embodiment, the auxiliary linkage assembly 5 includes a sliding member 51 and a connecting rod 52. The sliding member 51 can be slidably installed on the flip assembly 1 along the height direction of the flip assembly 1. The two ends of the connecting rod 52 are respectively hinged to the sliding member 51 and the upper end of the flip chamber assembly 2.

[0142] That is, when the smoke collecting plate 11 is flipped open, the smoke collecting chamber 21 and the side slide rail 22 are driven by the connecting shaft 321 to rotate. Since a connecting rod 52 is connected between the smoke collecting chamber 21 and the sliding member 51, due to the length of the connecting rod 52, when the smoke collecting chamber 21 and the smoke collecting plate 11 rotate, the sliding member 51 slides downward along the smoke collecting plate 11, thereby driving the smoke collecting chamber 21 to slide upward relative to the side slide rail 22 and approach the smoke collecting plate 11, thereby increasing the depth of the smoke collecting chamber and improving the smoke collecting effect.

[0143] In this embodiment, the top of the smoke collecting cavity 21 is hinged to the connecting rod 52, which is more conducive to controlling the position of the smoke collecting cavity 21 relative to the smoke collecting plate 11, and can avoid interference between the connecting rod 52 and the smoke guiding boss 12 on the back side of the smoke collecting plate 11. In other embodiments, the smoke collecting cavity 21 can also be hinged to the connecting rod 52 at other positions.

[0144] Furthermore, when the flap assembly 1 is in a closed state, the connecting rod 52 extends straight from front to back or extends upwardly at an angle from front to back, so that when the sliding member 51 slides downward relative to the smoke collecting plate 11, the smoke collecting cavity 21 is pulled upward and close to the smoke collecting plate 11.

[0145] In order to improve the sliding convenience of the sliding member 51, in the present embodiment, a guide track 55 is installed on the back side of the cigarette collecting plate 11, and the guide track 55 extends along the height direction of the cigarette collecting plate 11. A guide groove is provided on the slide part, and the sliding member 51 is slidably installed in the guide groove to ensure the sliding stability and reliability of the sliding member 51.

[0146] In order to improve the connection convenience between the connecting rod and the smoke collecting chamber 21 and the sliding member 51, a first hinge shaft 53 is connected to the smoke collecting chamber 21, a second hinge shaft 54 ​​is connected to the sliding member 51, and both ends of the connecting rod 52 are respectively sleeved on the first hinge shaft 53 and the second hinge shaft 54. The first hinge shaft 53 and the second hinge shaft 54 ​​can be, but are not limited to, pins or other structures that can realize the hinge connection of the connecting rod 52.

[0147] In this embodiment, the left and right side walls of the smoke inlet 211 are provided with side baffle portions 24, which extend backward to prevent the smoke from flowing to the side slide rail 22 and causing more smoke to adhere to the slide rail portion, thereby preventing the side frame portion and the slide rail portion from sticking together and affecting the sliding of the smoke collecting cavity 21, thereby improving the sliding smoothness of the smoke collecting cavity 21.

[0148] In order to ensure the stability and smoothness of the movement of the smoke collecting cavity 21 , at least two auxiliary linkage components 5 are arranged at intervals along the left-right direction to ensure the stability of the force applied to the smoke collecting cavity 21 .

[0149] Embodiment 3

[0150] This embodiment provides a smoke collecting device 100 and a range hood, and the smoke collecting device 100 provided in this embodiment has a structure substantially the same as that in the first embodiment, with only some differences in configuration. This embodiment will not repeat the same structure as that in the above embodiment.

[0151] like Fig.16 and Fig.17 As shown, in this embodiment, the mounting shaft hole 23 includes a first hole portion 231 and a second hole portion 232 connected to the front end of the first hole portion 231. When the flap assembly 1 closes the smoke inlet 211, the connecting shaft 321 is located at the rear end of the first hole portion 231. The shape of the first hole portion 231 is consistent with the running track of the connecting shaft 321 when the flap assembly 1 is flipped from the closed state to the open preset angle. The movement of the connecting shaft 321 along the second hole portion 232 drives the flip chamber assembly 2 to flip. When the flap assembly 1 is at the maximum opening angle, the connecting shaft 321 is located at the upper part of the second hole portion 232.

[0152] The smoke collecting device 100 and the range hood provided in the present embodiment, when the angle at which the flap assembly 1 is opened is less than or equal to a preset angle, the flap assembly 1 flips outwards to drive the connecting shaft 321 to slide in the first hole portion 231, and since the trajectory of the first hole portion 231 is consistent with the movement trajectory of the connecting shaft 321, the movement of the connecting shaft 321 will not drive the movement of the flip chamber assembly 2, so that when the opening angle of the flap assembly 1 is less than or equal to the preset angle, the movement of the flap assembly 1 flipping outwards will not drive the movement of the flip chamber assembly 2; when the flap assembly 1 continues to flip outwards from the preset angle, the connecting shaft 321 continues to move forward, and since the second hole portion 232 extends upward, the previous movement of the connecting shaft 321 pulls the upper end of the flip chamber assembly 2 to flip forward, thereby causing the flip chamber assembly 2 and the flap assembly 1 to be linked, and the flip chamber assembly 2 flips out to increase the size of the smoke collecting chamber, thereby improving the smoke collecting effect.

[0153] The above-mentioned arrangement is beneficial for the smoke collecting device 100 and the range hood to control the activities of the flip chamber assembly 2 and the flap assembly 1 according to the size of the oil smoke. For example, when the amount of oil smoke is small, the flip angle of the flap assembly 1 can be controlled to be less than or equal to a preset angle, so that the flap assembly 1 opens outward and the flip chamber assembly 2 does not flip relative to the smoke collecting hood 6, thereby achieving oil fume extraction and reducing the driving cost of the drive motor 4; when the amount of oil smoke is large, the angle of opening of the flap assembly 1 is greater than the preset angle, so that the flip chamber assembly 2 flips out with the flap assembly 1, thereby making the smoke collecting chamber closer to the stove and increasing the smoke collecting area of ​​the smoke collecting chamber, thereby improving the smoke collecting effect and ensuring the oil fume extraction effect.

[0154] In this embodiment, the first hole portion 231 is an arc-shaped hole portion, the opening of which is arranged upward, and the second hole portion 232 is a long hole portion extending along the length direction of the flip smoke chamber.

[0155] Furthermore, when the flap assembly 1 is flipped closed, the movement of the connecting shaft 321 in the first hole portion 231 will not drive the flip chamber assembly 2 to move. In order to ensure that the flip chamber assembly 2 is accurately and reliably reset, the smoke collecting mechanism also includes a reset member 40, which is used to apply an elastic force to the flip chamber assembly 2 to flip backward.

[0156] Furthermore, the reset member 40 is a spring, which extends in the front-rear direction, with the rear end of the spring mounted on the back plate 611 or the bottom of the smoke collecting chamber 63 , and the front end of the spring connected to the flip chamber assembly 2 .

[0157] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
