Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a movable cavity and flap assembly as well as an oil fume treatment device. Background Technology

[0002] In the prior art, range hoods include a movable cavity and a flap assembly. The movable cavity and flap assembly typically include a flap, a movable cavity, a drive mechanism, and a complex linkage assembly. The output end of the drive mechanism is connected to the flap through the complex linkage assembly. The flap is rotatably connected to the movable cavity. When the drive mechanism is working, the flap can flip relative to the smoke collection cavity through the transmission of the linkage assembly. At the same time, the flap can also drive the movable cavity to flip relative to the smoke collection cavity.

[0003] However, the linkage assembly in existing technology has a complex structure involving numerous links. During deformation, the linkage assembly is prone to jamming, and the connection between the flap and the movable cavity is also susceptible to jamming. This affects the normal flipping drive of the flap and the movable cavity, resulting in poor operational stability of the flap and movable cavity assembly. Furthermore, the complex structure of the linkage assembly in existing technology leads to a large overall volume, affecting the actual effective fume extraction volume of the range hood and resulting in relatively poor fume extraction performance of the fume treatment device.

[0004] Therefore, there is an urgent need to design a new movable chamber and flap assembly, as well as an oil fume treatment device, to improve the poor operational stability of the movable chamber and flap assembly and the poor oil fume extraction effect of the oil fume treatment device. Utility Model Content

[0005] One objective of this invention is to provide a movable cavity and a flap assembly, which effectively improves the operational stability of the movable cavity and the flap assembly, and effectively enhances the fume extraction effect of the fume treatment device.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A movable chamber and flap assembly, which can be used in conjunction with the smoke collection chamber of an oil fume treatment device, the movable chamber and flap assembly comprising:

[0008] The movable chamber and the flap are rotatably connected to the smoke collection chamber, and a sliding groove is provided on the movable chamber.

[0009] A rotating component, rotatably connected to the smoke collection chamber and capable of sliding along a groove, is fixedly connected to a flap plate; and

[0010] The drive mechanism includes a drive mechanism body and an output end that can move linearly relative to it. The drive mechanism body is rotatably connected to the smoke collection chamber, and the output end is rotatably connected to a rotating component.

[0011] As an optional solution, the rotating component includes a rotating component body, a first connecting arm, a second connecting arm, a third connecting arm, and a fourth connecting arm. The first connecting arm, the second connecting arm, the third connecting arm, and the fourth connecting arm are all disposed on the rotating component body. The first connecting arm is rotatably connected to the smoke collection chamber, the second connecting arm is inserted into the slide groove and slides along the slide groove, the third connecting arm is fixedly connected to the flap, and the fourth connecting arm is rotatably connected to the output end.

[0012] As an alternative, the second connecting arm includes a connecting arm body and a connector disposed thereon. The connecting arm body is fixedly connected to the rotating body, and the connector is inserted into the slide groove and can slide relative to the slide groove.

[0013] As an alternative, the connector includes a connecting part and a rotating part. One end of the connecting part is fixedly connected to the main body of the connecting arm, and the rotating part is rotatably sleeved on the other end of the connecting part. The rotating part is located in the slide groove, and the outer peripheral surface of the rotating part abuts against the inner wall surface of the slide groove and can slide along the inner wall surface of the slide groove.

[0014] As an alternative, the rotating body, the first connecting arm, the second connecting arm, the third connecting arm, and the fourth connecting arm are integrally formed.

[0015] As an optional solution, at least two rotating components are provided, and the at least two rotating components are arranged at intervals along the rotation direction of the flap. The movable cavity and flap assembly also include a connecting rod, and two adjacent rotating components are connected by the connecting rod.

[0016] As an alternative, the rotating component includes a rotating component body and a mounting protrusion disposed thereon. The movable cavity and flap assembly also includes a fixing member. The mounting protrusion is inserted into the end of the connecting rod, and the fixing member securely connects the mounting protrusion to the connecting rod.

[0017] As an alternative, the cross-section of the mounting protrusion is non-circular.

[0018] As an alternative, the rotating component and the drive mechanism are located on the leeward side of the smoke collection chamber, and a first clearance hole is provided on the smoke collection chamber, through which the rotating component can pass and be fixedly connected to the flap.

[0019] Another objective of this invention is to provide an oil fume treatment device that effectively improves the operational stability of the movable chamber and the flap assembly, and effectively enhances the oil fume extraction effect of the oil fume treatment device.

[0020] To achieve this objective, the present invention adopts the following technical solution:

[0021] An oil fume treatment device includes a smoke collection chamber, and the oil fume treatment device also includes the above-mentioned movable chamber and flap assembly. The movable chamber, the rotating component and the drive mechanism body are respectively rotatably connected to the smoke collection chamber.

[0022] The beneficial effects of this utility model are:

[0023] The movable cavity and flap assembly provided by this utility model includes a movable cavity, a flap, a rotating component, and a driving mechanism. The movable cavity is rotatably connected to the smoke collection cavity. A sliding groove is provided on the movable cavity. The rotating component is rotatably connected to the smoke collection cavity and can slide along the sliding groove. The rotating component is fixedly connected to the flap. The driving mechanism includes a driving mechanism body and an output end that can make linear motion relative to it. The driving mechanism body is rotatably connected to the smoke collection cavity, and the output end is rotatably connected to the rotating component.

[0024] When the drive mechanism is working, the drive mechanism body pushes the output end forward and retracts, and the output end drives the rotating part to rotate relative to the smoke collection chamber. The rotating part pushes the flap fixed to it, so that the flap forms an opening and closing action. In addition, during the rotation of the rotating part relative to the smoke collection chamber, the rotating part can also slide along the slide groove. The combined motion of rotation and translation of the rotating part causes the rotating part to push the movable cavity to rotate relative to the smoke collection chamber, thereby realizing the flipping motion of the movable cavity relative to the smoke collection chamber.

[0025] Compared to the existing structures of movable cavity and flap assembly, the movable cavity and flap assembly of this utility model, through the simple structural design of the rotating component, uses only one drive mechanism as the power source. It can provide power to the movable cavity while pushing the flap, realizing the synchronous drive of the flap and movable cavity by the drive mechanism. Compared to the more complex linkage assembly in the prior art, the rotating component has a simple structure, and the movable cavity and flap assembly is less prone to jamming during state switching. It can ensure that the movable cavity and flap assembly can always be used normally and has good operational stability.

[0026] Furthermore, in this utility model, the flap and the movable cavity are not directly connected. During the state switching process, the movable cavity and the flap assembly are less likely to get stuck between the flap and the movable cavity. This allows the flap and the movable cavity to open or close simultaneously without interference. This ensures that the movable cavity and the flap assembly can always be used normally and has good operational stability.

[0027] Furthermore, compared to the large overall volume of the connecting rod assembly in the prior art, the rotating component of this utility model has a simple structure and small volume. The various parts of the movable cavity and the flap assembly are arranged compactly, which effectively increases the actual effective volume of the fume extraction cavity of the fume collection system and can better improve the fume extraction effect of the fume treatment device.

[0028] The oil fume treatment device provided by this utility model, by applying the above-mentioned movable chamber and flap assembly, can effectively improve the operational stability of the movable chamber and flap assembly, and effectively enhance the oil fume extraction effect of the oil fume treatment device.

[0046] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.

[0047] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] In the description of the embodiments disclosed herein, terms such as "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used merely for distinction in description and have no special meaning.

[0050] like Figure 1As shown, this disclosure provides an oil fume treatment device 1000. The oil fume treatment device 1000 can be any type of device with oil fume treatment function, such as a top-mounted range hood, a side-suction range hood, or a top-suction range hood. All types of devices with oil fume treatment function are within the protection scope of this disclosure. This disclosure uses a top-mounted range hood as an example to describe the structure of the oil fume treatment device 1000.

[0051] like Figure 1 As shown, the fume treatment device 1000 includes a fan housing 200, a fume collection system 100, and a connecting pipe 300. One end of the connecting pipe 300 is connected to the fan housing 200, and the other end of the connecting pipe 300 is connected to the fume collection system 100. Figure 1 As shown, the fan housing 200 includes a fan (not shown in the figure). The fan (not shown in the figure) can generate negative pressure, which allows the oil fumes to pass through the smoke collection system 100, the connecting pipe 300 and the fan housing 200 in sequence before being discharged outdoors.

[0052] like Figure 1 As shown, the fan housing 200 is installed above the ceiling 3000, and the fan housing 200 is detachably connected to the ceiling wall 2000. Because the fan housing 200 is located above the ceiling 3000, far from the user, the ceiling 3000 can isolate the noise generated during the operation of the fan housing 200, reducing the impact of noise on the user and improving the user experience. When the height of the wall 2000 varies, the length of the connecting pipe 300 can be adjusted to ensure the operational reliability of the fume treatment device 1000. Specifically, as... Figure 1 As shown, the connecting pipe 300 includes a first connecting joint 310, a connecting pipe body 320, and a second connecting joint 330 connected in sequence. The first connecting joint 310 is connected to the fan housing 200, and the second connecting joint 330 is connected to the smoke collection system 100. The connecting pipe body 320 is a retractable pipe to allow adjustment of the overall length of the connecting pipe 300. The first connecting joint 310 and the second connecting joint 330 can be rigid connecting joints, thereby enabling a stable connection between the connecting pipe 300 and the fan housing 200 and the smoke collection system 100, respectively.

[0053] like Figure 2As shown, the smoke collection system 100 includes a movable cavity and a flap assembly 10, and a smoke collection chamber 20. The movable cavity and flap assembly 10 includes a movable cavity 11, a flap 12, and a drive mechanism 14 (not shown in the figure). The drive mechanism 14 is driven to the flap 12 and the movable cavity 11. The drive mechanism 14 can drive the flap 12 to rotate relative to the smoke collection chamber 20 in the M direction. When the flap 12 is in the open state, it can achieve a better smoke collection effect, effectively improving the smoke extraction effect of the smoke treatment device 1000. The movable cavity 11 has a smoke inlet 1111, through which smoke from outside the smoke treatment device 1000 can enter the smoke collection chamber 20. The drive mechanism 14 can also drive the movable cavity 11 to rotate relative to the smoke collection chamber 20 in the N direction, enabling the movable cavity 11 to switch between a first position retracted inside the smoke collection chamber 20 and a second position extended outside the smoke collection chamber 20. When the movable cavity 11 is in the first position, the flap 12 blocks the smoke inlet 1111, and the smoke collection system 100 is in a closed state, preventing the oil fumes or odors inside the smoke collection system 100 from spreading into the room. When the movable cavity 11 is in the second position, the smoke inlet 1111 moves forward and downward, and the smoke inlet 1111 is closer to the cooking area, allowing the smoke collection system 100 to better absorb the oil fumes, effectively improving the oil fume extraction effect of the oil fume treatment device 1000. For example, the movable cavity 11 can be in various shapes such as triangle, trapezoid, rectangle, triangular-like, trapezoidal-like, and rectangular.

[0054] In existing technologies, the movable chamber and flap assembly typically include a complex linkage assembly. The output end of the drive mechanism is connected to the flap via this complex linkage assembly. The flap is rotatably connected to the movable chamber. When the drive mechanism operates, the flap can rotate relative to the smoke collection chamber through the transmission of the linkage assembly, and the flap can also drive the movable chamber to rotate relative to the smoke collection chamber. However, the linkage assembly in existing technologies has a complex structure involving many links. During deformation, the linkage assembly is prone to jamming, and the connection between the flap and the movable chamber is also prone to jamming, thus affecting the normal rotation drive of the flap and the movable chamber, resulting in poor operational stability of the movable chamber and flap assembly. Furthermore, the complex structure and large overall volume of the linkage assembly in existing technologies affect the actual effective volume of the smoke collection system's fume extraction chamber, leading to relatively poor fume extraction performance of the fume treatment device.

[0055] To solve the above problems, such as Figure 3 and Figure 4As shown, the movable cavity and flap assembly 10 includes a movable cavity 11, a flap 12, a rotating component 13, and a drive mechanism 14. The movable cavity 11 is rotatably connected to the smoke collection cavity 20. A sliding groove 1121 is provided on the movable cavity 11. The rotating component 13 is rotatably connected to the smoke collection cavity 20 and can slide along the sliding groove 1121. The rotating component 13 is fixedly connected to the flap 12. The drive mechanism 14 includes a drive mechanism body 141 and an output end 142 that can perform linear motion relative to it. The drive mechanism body 141 is rotatably connected to the smoke collection cavity 20, and the output end 142 is rotatably connected to the rotating component 13. When the drive mechanism 14 is working, the drive mechanism body 141 pushes the output end 142 forward and retracts it. The output end 142 drives the rotating part 13 to rotate relative to the smoke collection chamber 20. The rotating part 13 pushes the flap 12 fixed to it, so that the flap 12 forms an opening and closing action. In addition, during the rotation of the rotating part 13 relative to the smoke collection chamber 20, the rotating part 13 can also slide along the slide groove 1121. The combined rotation and translation motion of the rotating part 13 causes the rotating part 13 to push the movable cavity 11 to rotate relative to the smoke collection chamber 20, thereby realizing the flipping motion of the movable cavity 11 relative to the smoke collection chamber 20.

[0056] Compared to the structure of the active cavity and flap assembly in existing technologies, such as Figure 3 and Figure 4 As shown, the movable cavity and flap assembly 10 disclosed in this embodiment uses a simple structural design of the rotating component 13 and only one drive mechanism 14 as the power source. It can provide power to the movable cavity 11 while pushing the flap 12, so as to realize the synchronous drive of the flap 12 and the movable cavity 11 by the drive mechanism 14. Compared with the more complex linkage assembly in the prior art, the rotating component 13 of this embodiment has a simple structure. The movable cavity and flap assembly 10 is not prone to jamming during the state switching process, which can ensure that the movable cavity and flap assembly 10 can always be used normally and has good stability during operation.

[0057] In addition, such as Figure 3 and Figure 4 As shown, in the embodiment of this disclosure, the flap 12 and the movable cavity 11 in the movable cavity and flap assembly 10 are not directly connected. During the state switching process, the movable cavity and flap assembly 10 is less likely to get stuck between the flap 12 and the movable cavity 11. It can realize that the flap 12 and the movable cavity 11 can be opened or closed at the same time, and the flap 12 and the movable cavity 11 do not interfere with each other. It can ensure that the movable cavity and flap assembly 10 can always be used normally and the stability of the movable cavity and flap assembly 10 during operation is good.

[0058] Furthermore, compared to existing linkage assemblies with a larger overall volume, such as Figure 3 and Figure 4As shown, the rotating component 13 of this embodiment has a simple structure and small size. The various parts of the movable cavity and the flap assembly 10 are arranged compactly, which can effectively increase the volume of the actual effective oil fume absorption cavity of the smoke collection system 100 and improve the oil fume absorption effect of the oil fume treatment device 1000.

[0059] like Figure 5 As shown, the rotating component 13 includes a rotating component body 131, a first connecting arm 132, a second connecting arm 133, a third connecting arm 134, and a fourth connecting arm 135. The first connecting arm 132, the second connecting arm 133, the third connecting arm 134, and the fourth connecting arm 135 are all disposed on the rotating component body 131. For example... Figure 3 As shown, the first connecting arm 132 is rotatably connected to the smoke collection chamber 20, the second connecting arm 133 is inserted into the slide groove 1121 and slides along the slide groove 1121, and the fourth connecting arm 135 is rotatably connected to the output end 142, as shown. Figure 4 As shown, the third connecting arm 134 is fixedly connected to the flap 12. The rotating component 13 has a simple structure, and the arrangement of the rotating component 13, the smoke collection chamber 20, the movable chamber 11, the drive mechanism 14, and the flap 12 is compact. It can also realize the rapid assembly of the rotating component 13 with the smoke collection chamber 20, the movable chamber 11, the drive mechanism 14, and the flap 12 respectively, thereby improving the installation efficiency of the smoke collection system 100.

[0060] Among them, such as Figure 5 As shown, the rotating component body 131, the first connecting arm 132, the second connecting arm 133, the third connecting arm 134, and the fourth connecting arm 135 are integrally formed, enabling rapid processing of the rotating component 13 and resulting in a simple structure and low cost. For example, the rotating component 13 can be formed by injection molding, casting, extrusion, or other processes.

[0061] like Figure 3 , Figure 4 and Figure 6 As shown, the smoke collection chamber 20 includes a smoke collection chamber body 21 and a first mounting base 22 fixedly disposed thereon. A first connecting arm 132 is rotatably connected to the first mounting base 22. Through the cooperation of the first connecting arm 132 and the first mounting base 22, a good rotation effect of the rotating component 13 relative to the smoke collection chamber 20 can be achieved. For example, the rotating component 13 and the smoke collection chamber 20 can be rotatably connected through structures such as pins and hinges.

[0062] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the smoke collection chamber 20 also includes a second mounting base 23, which is fixedly mounted on the smoke collection chamber body 21. The movable chamber 11 includes a movable chamber body 111 and a hinge 113. The smoke inlet 1111 is opened in the movable chamber body 111. The second mounting base 23 is connected to the movable chamber body 111 through the hinge 113. Through the setting of the hinge 113, the movable chamber 11 can achieve a better rotation effect relative to the smoke collection chamber body 21.

[0063] like Figure 3 , Figure 4 and Figure 6 As shown, the smoke collection chamber 20 also includes a third mounting base 24, which is fixedly mounted on the smoke collection chamber body 21. The drive mechanism body 141 is rotatably connected to the third mounting base 24, thereby achieving a better rotation effect between the drive mechanism 14 and the smoke collection chamber 20. For example, the drive mechanism 14 and the smoke collection chamber 20 can be rotatably connected by a pin, hinge, etc., which is simple in structure and easy to assemble.

[0064] like Figure 2 and Figure 4 As shown, the rotating component 13 and the driving mechanism 14 are located on the leeward side of the smoke collection chamber 20. The rotating component 13 and the driving mechanism 14 are concealed inside the smoke collection chamber 20, resulting in a more aesthetically pleasing overall appearance of the fume treatment device 1000. Furthermore, as... Figure 2 and Figure 4 As shown, a first clearance hole 211 is provided on the main body 21 of the smoke collection chamber. The rotating part 13 can pass through the first clearance hole 211 and be fixedly connected to the flap 12. The setting of the first clearance hole 211 can also prevent the rotating part 13 from interfering with the smoke collection chamber 20.

[0065] like Figures 2-4 As shown, a second clearance hole 212 is provided on the main body 21 of the smoke collection chamber. The movable cavity 11 can switch between a second position extending outside the smoke collection chamber 20 and a first position retracted inside the smoke collection chamber 20 through the second clearance hole 212.

[0066] like Figure 2 and Figure 4 As shown, the flap 12 includes a flap body 121 and a connector 122 fixedly mounted thereon. The third connecting arm 134 is fixedly connected to the connector 122, thereby realizing the rapid assembly and stable connection of the flap 12 and the rotating part 13.

[0067] like Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the second connecting arm 133 includes a connecting arm body 1331 and a connector 1332 disposed thereon. The connecting arm body 1331 is fixedly connected to the rotating body 131. The connector 1332 is inserted into the slide groove 1121 and can slide relative to the slide groove 1121. The connector 1332 is inserted into the slide groove 1121, which can prevent the connector 1332 from detaching from the slide groove 1121.

[0068] like Figure 3 , Figure 4 and Figure 5 As shown, the connector 1332 includes a connecting portion 13321 and a rotating portion 13322. One end of the connecting portion 13321 is fixedly connected to the connecting arm body 1331. The rotating portion 13322 is rotatably sleeved on the other end of the connecting portion 13321. The rotating portion 13322 is located in the slide groove 1121. The outer peripheral surface of the rotating portion 13322 abuts against the inner wall surface of the slide groove 1121 and can slide along the inner wall surface of the slide groove 1121. The rotating portion 13322 prevents the connector 1332 from getting stuck during the sliding process in the slide groove 1121, ensuring smooth sliding of the connector 1332 in the slide groove 1121. For example, the rotating portion 13322 can be a roller, bearing, etc.

[0069] Figure 3 , Figure 6 and Figure 7 As shown, the movable cavity 11 also includes a bracket 112, which is disposed on the movable cavity body 111. The bracket 112 is located on one side of the movable cavity body 111 along the width direction of the movable cavity body 111. The sliding groove 1121 is disposed on the bracket 112 to facilitate the insertion and sliding engagement of the connector 1332 and the sliding groove 1121.

[0070] like Figure 6 As shown, at least two rotating parts 13 are provided, and the at least two rotating parts 13 are arranged at intervals along the rotation direction of the flap 12. The movable cavity and flap assembly 10 also includes a connecting rod 15. Two adjacent rotating parts 13 are connected by the connecting rod 15. The rotating parts 13 directly connected to the drive mechanism 14 can drive other rotating parts 13 to move synchronously, ensuring good stability during the rotation of the movable cavity and flap assembly 10.

[0071] like Figures 3-5As shown, the rotating component 13 includes a rotating component body 131 and a mounting protrusion 136 disposed thereon. The movable cavity and flap assembly 10 also includes a fixing member (not shown in the figure). The mounting protrusion 136 is inserted into the end of the connecting rod 15, and the fixing member fixes the mounting protrusion 136 and the connecting rod 15 together, thereby realizing the rapid assembly and stable connection of the rotating component 13 and the connecting rod 15. For example, the fixing member can be a screw, pin, snap-fit ​​assembly, threaded connection structure, etc. All structures that can realize the detachable connection between the mounting protrusion 136 and the connecting rod 15 are within the protection scope of the embodiments of this disclosure.

[0072] like Figure 5 As shown, the cross-section of the mounting protrusion 136 is non-circular, which can prevent relative rotation between the rotating member 13 and the connecting rod 15, thereby ensuring a stable connection between the mounting protrusion 136 and the connecting rod 15. For example, the non-circular shape can be polygonal, elliptical, etc., and all non-circular shapes are within the protection scope of the embodiments of this disclosure.

[0073] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
