Description

Technical Field

[0001] This utility model relates to oil fume purification components, and more particularly to an air outlet component and a range hood. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It can quickly remove the waste from the stove and the fumes produced during cooking and exhaust them outdoors, reducing pollution and purifying the air.

[0003] For example, Chinese utility model patent application number 202221537701.5 discloses an air outlet component and a range hood using the air outlet component. The air outlet component includes an air outlet hood and a smoke exhaust pipe disposed on the air outlet hood. A transition pipe is also provided between the air outlet hood and the smoke exhaust pipe. The transition pipe is hollow and has a first end and a second end opposite to each other. The first end is connected to the output end of the air outlet hood, and the second end is connected to the input end of the smoke exhaust pipe, so that the air outlet hood and the smoke exhaust pipe are in fluid communication. The air outlet component also includes a snap fastener component that can be detachably connected between the transition pipe and the air outlet hood.

[0004] Most range hoods on the market use a method where the exhaust pipe is directly fitted onto the air outlet of the exhaust hood, and then fixed and sealed with screws and sealing tape. Due to the limited space between the exhaust hood and the wall where the range hood is installed, and the limitations of the installation environment and the skill level of the installers, it is inconvenient to wrap the tape. Improper operation may result in poor adhesion of the tape, posing a risk of oil and smoke leakage.

[0005] The aforementioned patent employs an additional exhaust pipe mounting adapter to fix the exhaust pipe to the adapter, which is then assembled with the exhaust hood. A seal is achieved by pressing the two parts together using a snap-fit ​​structure. However, since the adapter and exhaust hood are generally injection-molded parts, their overall strength is insufficient, making them prone to deformation under stress, thus affecting the sealing performance. Utility Model Content

[0006] The first technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing an air outlet component that can improve overall strength and prevent sealing problems caused by deformation under stress.

[0007] The second technical problem to be solved by this utility model is to provide a range hood that uses the air outlet component.

[0008] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: an air outlet assembly, including an air outlet hood and a connector connecting the air outlet hood and the smoke exhaust pipe, the connector being a hollow cylinder, the air outlet hood being snapped into the connector, characterized in that: the air outlet assembly further includes a reinforcing member for improving the structural strength and rigidity of the air outlet assembly, the reinforcing member being disposed on the inner side of the connection between the air outlet hood and the connector.

[0009] By installing a reinforcing member on the inside of the connection between the air outlet cover and the adapter, the overall strength of the air outlet assembly can be improved, preventing sealing problems caused by deformation under stress.

[0010] To provide a reinforcing member, the reinforcing member includes a hollow cylindrical reinforcing member body and a flange extending radially outward from the bottom of the reinforcing member body. The flange is disposed on the air outlet cover, and the reinforcing member body abuts against the adapter.

[0011] To provide reinforcement, the flange of the reinforcement is mounted on the inner side of the air outlet hood, the inner side of the air outlet hood is provided with a screw post, the flange is provided with a screw hole for screw connection with the screw post, and the inner side of the adapter is provided with an abutment portion that abuts against the outer side of the reinforcement body.

[0012] To connect the adapter to the air outlet cover, the adapter has a buckle protruding outward on its peripheral wall. The air outlet cover includes a cover body, and the top of the cover body has an inner wall and an outer wall that are radially spaced and both extend upward. The inner wall, the outer wall, and the top of the cover body form a receiving groove. The adapter is placed between the inner wall and the outer wall. The outer wall of the air outlet cover has a guide groove for the buckle to pass through, which runs from top to bottom, and a slot, which runs circumferentially along the outer wall. The guide groove and the slot are connected, and the buckle is rotatably engaged with the slot.

[0013] To prevent the buckle from retracting after engaging with the slot, the air outlet assembly also includes a limiting member to prevent the buckle from retracting after engaging with the slot. The limiting member cooperates with the buckle to prevent the buckle from disengaging from the slot. The limiting member includes a limiting member body, a snap-fit ​​part, and a connecting part. The limiting member body and the connecting part are spaced apart. The top of the limiting member body and the snap-fit ​​part are connected by the connecting part. A snap-fit ​​strip is provided on the outer wall outside the guide groove to engage with the limiting member. The connecting part is mounted on the top of the snap-fit ​​strip. The limiting member body is located in the guide groove inside the snap-fit ​​strip. The snap-fit ​​part is located on the outer side of the snap-fit ​​strip and can engage with the bottom of the snap-fit ​​strip.

[0014] To prevent the buckle from detaching from the slot and to prevent the limiting member from being installed incorrectly, the limiting member body includes a first end near the slot and a second end opposite to the first end. The first end is straight and extends away from the card strip, while the second end is inclined and gradually extends away from the slot from the side near the card strip towards the adapter. The shape of the guide groove is adapted to the shape of the limiting member body.

[0015] To facilitate disassembly and assembly, the limiting component is also provided with a gripper for hand gripping, which is located on the side of the locking part away from the locking strip.

[0016] To reinforce the structure and prevent slippage, the outer wall of the adapter is provided with ribs that reinforce the structure and prevent slippage. The ribs extend longitudinally and are spaced apart on the circumference of the outer wall of the adapter.

[0017] To achieve a sealing effect, the air outlet assembly also includes a sealing ring disposed in the receiving groove, and the bottom of the adapter abuts against the sealing ring.

[0018] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: the range hood uses the air outlet component.

[0019] Compared with the prior art, the advantages of this utility model are: by setting a reinforcing member on the inner side of the connection between the air outlet cover and the adapter, the overall strength of the air outlet assembly can be improved, and the sealing problem caused by deformation under force can be prevented.

They 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. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0030] See Figures 1 to 8 An air outlet assembly includes an air outlet hood 1 and an adapter 2 connecting the air outlet hood 1 and the exhaust pipe 100. The adapter 2 is a hollow cylinder, and the air outlet hood 1 and the adapter 2 are snapped together. This air outlet assembly can be used in range hoods. The range hood can be controlled by a voice module. A controller, a voice receiving module, and a voice parsing module can be installed in the range hood. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the range hood's fan and other components to perform corresponding operations, thereby achieving intelligent control of the range hood and improving the user experience.

[0031] See Figure 1 and Figure 8 The top circumferential surface of the adapter 2 has an inner support plate 24 and an outer support plate 25. The inner support plate 24 and the outer support plate 25 are arranged radially from the inside out. One end of the exhaust pipe is located between the inner support plate 24 and the outer support plate 25. The exhaust pipe 100 can be fixed to the outer support plate 25 with screws and tape. Because the adapter 2 and the exhaust hood 1 are designed separately, the operation between the exhaust pipe 100 and the adapter 2 is not limited by space, providing greater flexibility. During installation, the exhaust pipe 100 and the adapter 2 can be assembled and connected first.

[0032] To ensure long-term use and to smoothly guide the oil collected in the exhaust pipe into the oil circuit of the range hood, a first oil guide port (not shown) recessed from the top downwards can be provided on the inner support plate 24. A certain number of second oil guide ports (not shown) are also provided on the inner wall of the exhaust hood 1 at the mating structure with the check valve inside.

[0033] See Figures 3-5The air outlet assembly also includes a reinforcing member 3 for improving the structural strength and rigidity of the air outlet assembly. The reinforcing member 3 is disposed on the inner side of the connection between the air outlet shroud 1 and the adapter 2. The reinforcing member 3 includes a hollow cylindrical reinforcing member body 31 and a flange 32 extending radially outward from the bottom of the reinforcing member body 31. The flange 32 is disposed on the air outlet shroud 1, and the reinforcing member body 31 abuts against the adapter 2.

[0034] The flange 32 of the reinforcing member 3 is mounted on the inner side of the air outlet shroud 1. A screw post 11 is provided on the inner side of the air outlet shroud 1, and a screw hole 321 is provided on the flange 32 for screw connection with the screw post 11. The inner side of the adapter 2 is provided with an abutting part 21 that abuts against the outer side of the reinforcing member body 31.

[0035] See Figures 4-5 The air outlet hood 1 includes a hood body 12. The top of the hood body 12 has an inner wall 13 and an outer wall 14, both extending upwards and radially spaced. The inner wall 13, outer wall 14, and the top of the hood body 12 form a receiving groove 15. The air outlet assembly also includes a sealing ring 5 disposed within the receiving groove 15. A connecting member 2 is positioned between the inner wall 13 and the outer wall 14, with its bottom abutting against the sealing ring 5. To reduce the contact area with the sealing ring 5 and apply greater pressure, resulting in a better sealing effect, the portion of the connecting member 2 that abuts against the sealing ring 5 has a downwardly convex arc-shaped structure. To ensure the sealing effect of the sealing ring 5, the compression of the sealing ring 5 is preferably controlled between 15% and 30%.

[0036] See Figure 2 and Figures 6-8 The adapter 2 has a buckle 22 protruding outward on its peripheral wall. The outer wall 14 of the air outlet shroud 1 has a guide groove 141 for the buckle 22 to pass through, which is formed from top to bottom, and a slot 142 that is formed along the circumference of the outer wall 14. The guide groove 141 and the slot 142 are connected. The buckle 22 is rotated and engaged with the slot 142, thereby realizing quick assembly and disassembly between the adapter 2 and the air outlet shroud 1.

[0037] See Figure 8 The top of the corresponding slot 142 on the outer wall 14 of the air outlet shroud 1 has a first guide slope 144, which gradually extends from bottom to top towards the guide groove 141. The top of the buckle 22 has a second guide slope 221 that guides and engages with the first guide slope 144. To facilitate the installation of the adapter 2, the first guide slope 144 and the second guide slope 221 guide and engage, thereby guiding the buckle 22 to rotate and press against the sealing ring 5 during installation. The slot 142 has an interference fit with the buckle 22, forming a pressing force on the sealing ring 5, achieving a better sealing effect.

[0038] See Figures 7-8The number of buckles 22 and slots 142 corresponds to the number of buckles 22. To ensure a sealing effect, the number of buckles 22 is preferably ≥4, and they are evenly distributed along the circumference of the adapter 2. In order to improve the injection molding processability and the strength and reliability of the snap-fit ​​structure, the buckles 22 can be hollow, and the structural strength of the slots 142 can be enhanced by increasing the wall thickness of the outer wall 14 on the air outlet shroud 1.

[0039] See Figures 2-6 The air outlet assembly also includes a limiting member 4 that prevents the latch 22 from retracting after engaging with the slot 142. The limiting member 4 cooperates with the latch 22 to prevent the latch 22 from disengaging from the slot 142. The limiting member 4 includes a limiting member body 41, a engaging portion 42, and a connecting portion 43. The limiting member body 41 and the connecting portion 43 are spaced apart, and the tops of the limiting member body 41 and the engaging portion 42 are connected by the connecting portion 43. A retaining strip 143 that engages with the limiting member 4 is provided on the outer wall 14 outside the guide groove 141. The connecting portion 43 is mounted on the top of the retaining strip 143. The limiting member body 41 is located in the guide groove 141 inside the retaining strip 143, and the engaging portion 42 is located on the outer side of the retaining strip 143 and can engage with the bottom of the retaining strip 143.

[0040] Because the buckle 22 exerts an upward force on the slot 142, in order to prevent the slot 142 from deforming, cracking, and losing its sealing performance after being subjected to long-term force, a retaining strip 143 is set. The upper end of the slot 142 of the air outlet cover 1 is not disconnected, but connected together in a whole circle, thereby improving the strength of the slot 142 and reducing the problem of sealing failure caused by deformation under force.

[0041] The limiting member body 41 includes a first end 411 near the card slot 142 and a second end 412 opposite to the first end 411. The first end 411 is straight and extends away from the card strip 143, and the second end 412 is inclined and gradually extends away from the card slot 142 from the side near the card strip 143 toward the adapter 2. The shape of the guide groove 141 is adapted to the shape of the limiting member body 41.

[0042] The limiting member 4 is also provided with a gripper 44 for hand gripping, so as to facilitate disassembly and assembly. The gripper 44 is located on the side of the locking part 42 away from the locking strip 143.

[0043] To prevent the adapter 2 from loosening due to vibration or human error during long-term operation of the range hood, a limiting component 4 is installed. After the adapter 2 is installed in place, the limiting component 4 is inserted. At least one limiting component is installed. The limiting component 4 can reliably prevent the adapter 2 from rotating and loosening. The limiting component 4 is fixed to the clip 143 on the upper edge of the air outlet hood 1 using a detachable snap-fit ​​structure. It can be installed and removed without the aid of tools, forming a reliable structure to prevent the adapter 2 from loosening.

[0044] Because of the separate design of the adapter 2, the structure of the slot 142 on the air outlet cover 1 and the buckle 22 of the adapter 2 are simplified, eliminating the anti-detachment protrusions and recesses commonly used in the market. The limiting component 4 has a reasonable structural design, is not easy to fall off, is easy to install, and has a foolproof structure to avoid incorrect installation.

[0045] See Figure 8 To improve the sealing effect, since the adapter 2 is generally an injection molded part, its dimensional stability is relatively poor due to the influence of injection molding process and environment. To increase the dimensional stability and ease of assembly and disassembly of the adapter 2, ribs 23 are provided on the outer wall of the adapter 2 to strengthen the structure and prevent slippage. The ribs 23 extend longitudinally, and each rib 23 is arranged at intervals on the circumference of the outer wall of the adapter 2.
