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] To facilitate the removal of cooking fumes, the exhaust hood needs to be connected to the exhaust pipe. Most range hoods on the market use a method where the exhaust pipe is directly fitted onto the exhaust port of the exhaust hood, secured and sealed with screws and sealing tape. However, due to the limited space between the exhaust hood and the wall where the range hood is installed, wrapping the tape is inconvenient. Furthermore, improper installation techniques can lead to poor tape adhesion, posing a risk of oil and smoke leaks. Additionally, using tape for sealing hinders future maintenance. After removing the tape, the grease on the exhaust pipe and exhaust hood surface can reduce the tape's adhesion, compromising the seal's reliability and increasing the risk of smoke leaks.

[0004] Some manufacturers use an additional flue adapter to bond the flue and adapter together with sealant. The adapter is then assembled with the exhaust hood, and an interference seal is achieved by pressing the two parts together using a snap-fit ​​structure. For example, Chinese utility model patent application number 202221537701.5 discloses an exhaust assembly and a range hood using the exhaust assembly. The exhaust assembly includes an exhaust hood and a flue installed on the exhaust hood. A transition pipe is also provided between the exhaust hood and the flue. The transition pipe is hollow and has a first end and a second end. The first end is connected to the output end of the exhaust hood, and the second end is connected to the input end of the flue, thereby enabling fluid communication between the exhaust hood and the flue. The exhaust assembly also includes a snap-fit ​​assembly that detachably connects the transition pipe and the exhaust hood.

[0005] However, due to manufacturing errors between the adapter and the exhaust hood, assembly gaps exist, leading to smoke and oil leaks. If the flue needs to be pre-embedded, the position of the locking structure on the adapter is random, making it difficult to accurately align with the corresponding locking structure on the exhaust hood. When they are rotated and locked, the flue and adapter twist, increasing installation difficulty and creating stress at the interface. In addition, due to unreasonable structural design, the buckles may deform or crack after locking, reducing the sealing effect and still causing smoke and oil leaks. Furthermore, some quick-release structures between adapters and exhaust hoods, although designed with anti-disengagement mechanisms, are unreliable due to unreasonable structures. 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 assembly in which the adapter can be directly inserted into the air outlet hood, making the connection between the adapter and the exhaust pipe more reliable.

[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 assembly and a connector for connecting the air outlet hood assembly to an external smoke exhaust pipe, the air outlet hood assembly including an air outlet hood, the connector including a connector ring, the connector ring having a first connecting portion for connecting to the smoke exhaust pipe and a second connecting portion for connecting to the air outlet hood, the first connecting portion and the second connecting portion being located at opposite ends of the connector ring; characterized in that:

[0009] The outer side of the peripheral wall of the second connecting part is provided with an annular first protruding rib, and the second connecting part is located inside the air outlet hood;

[0010] The air outlet shroud assembly also includes a locking member that can be fixed to the outside of the air outlet shroud, a portion of which passes through the air outlet shroud and abuts against the side of the first rib facing the first connecting portion.

[0011] By using the adapter and locking mechanism, the adapter can be directly inserted into the exhaust hood, eliminating the installation difficulties caused by twisting the exhaust pipe and the problem of the exhaust pipe being subjected to torsional stress for a long time, making the whole system more reliable.

[0012] Furthermore, to facilitate the connection between the second connecting part and the air outlet cover, the air outlet cover includes a cover body. The cover body is provided with an inner wall and an outer wall facing the top of the adapter. Both the inner wall and the outer wall extend upward from the top of the cover body toward the adapter. The outer wall is spaced around the outside of the inner wall. The bottom of the inner wall and the outer wall are connected by a bottom wall. An annular groove is formed between the inner wall and the outer wall. The second connecting part of the adapter is inserted into the groove of the air outlet cover.

[0013] Furthermore, to improve the sealing performance at the connection, an annular second rib is provided on the outer side of the peripheral wall of the second connection part. The first rib and the second rib are arranged at intervals along the axial direction of the transition ring. The second rib is located on the side of the first rib away from the first connection part. A groove is formed between the first rib and the second rib. A sealing ring is provided in the groove. The sealing ring protrudes radially outward from the first rib and the second rib, thereby abutting against the inner side of the outer wall of the air outlet shroud.

[0014] Furthermore, to improve the sealing of the connection, a sealing gasket is provided between the bottom of the second connection of the adapter and the bottom surface of the groove of the air outlet shroud.

[0015] Furthermore, in order to facilitate the fixing of the locking component relative to the air outlet cover and to enable it to cooperate with the adapter, an insertion hole is provided on the outer wall of the air outlet cover;

[0016] The locking member includes a body, a buckle formed on the body, and a limiting rib formed on the body. The buckle is used to fix the body to the outside of the outer wall of the air hood, and the limiting rib passes through the insertion hole and cooperates with the first rib.

[0017] Furthermore, to facilitate the fixing of the locking component relative to the air outlet cover and to enable it to cooperate with the adapter, a stop is provided on the outer side of the outer wall of the air outlet cover. The main body and the buckle pass through the space between the outer wall and the stop, and the buckle is engaged and fixed with the stop.

[0018] To prevent the locking element from detaching from the air outlet cover, there are two stops arranged symmetrically vertically. Each stop has an L-shaped vertical cross-section and a lateral extension extending outward from the outer wall and a longitudinal extension extending longitudinally from the end of the lateral extension away from the outer wall. The longitudinal extensions of the two stops extend towards each other. The buckle is inserted into one end of the stop and passes through the other end to fasten it.

[0019] To further prevent the locking parts from detaching from the air outlet cover, a connecting piece is provided between the two stop parts.

[0020] Furthermore, to facilitate the connection between the adapter and the exhaust pipe, the first connecting part is shaped like a slot into which the bottom of the exhaust pipe is inserted.

[0021] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a range hood, characterized in that: it applies the air outlet component as described above.

[0022] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows:

[0023] Compared with the prior art, the advantages of this utility model are: through the cooperation of the adapter and the locking part, the adapter can be directly inserted into the exhaust hood, eliminating the installation difficulties caused by twisting the exhaust pipe and the problem of the exhaust pipe being subjected to torsional stress for a long time, making the whole system more reliable.

[0036] Example 1

[0037] See Figures 1-9An air outlet assembly includes an air outlet hood assembly 1, from which exhaust fumes are discharged into a common flue through an exhaust pipe 100. The air outlet assembly also includes a connector 2 for connecting the air outlet hood assembly 1 and the exhaust pipe 100. 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.

[0038] The air outlet hood assembly 1 includes an air outlet hood 11 and a locking member 12. The air outlet hood 11 includes a hood body 111. The hood body 111 has an inner wall 112 and an outer wall 113 on its top facing the adapter 2. Both the inner wall 112 and the outer wall 113 extend upwards from the top of the hood body 111 toward the adapter 2. The outer wall 113 is spaced around the outside of the inner wall 112. The bottoms of the inner wall 112 and the outer wall 113 are connected by a bottom wall 114. The hood body 111, inner wall 112, outer wall 113, and bottom wall 114 can be integrally formed. An annular groove 115 is formed between the inner wall 112 and the outer wall 113. The height of the inner wall 112 can be lower than that of the outer wall 113.

[0039] The adapter 2 includes a generally hollow cylindrical adapter ring 21 with openings at both axial ends. A first connecting portion 22 is located on the top of the adapter ring 21 away from the exhaust hood assembly 1, and a second connecting portion 23 is located on the bottom of the adapter ring 21 facing the exhaust hood assembly 1. The first connecting portion 22 is a slot-shaped recess from top to bottom, and its vertical cross-section may be U-shaped. The bottom of the exhaust pipe 100 is inserted into the first connecting portion 22, and the two are preferably bonded together with sealant 24, thereby fixing the adapter 2 and the exhaust pipe 100. The exhaust pipe 100 and the adapter 2 can be pre-bonded at the factory.

[0040] The outer side of the peripheral wall of the second connecting part 23 is provided with an annular first rib 251 and a second rib 252. The first rib 251 and the second rib 252 are arranged at intervals along the axial direction of the transition ring 21, wherein the second rib 252 is closer to the air outlet shroud 11 (i.e., located below). Thus, a groove 253 is formed between the first rib 251 and the second rib 252. The groove 253 is also annular, and a sealing ring 3 can be provided in it. The sealing ring 3 protrudes radially outward from the first rib 251 and the second rib 253.

[0041] The second connecting part 23 of the adapter 2 is inserted into the groove 115 of the air outlet cover 11. At this time, the first rib 251 and the second rib 252 are also located in the groove 115. The sealing ring 3 set in the groove 253 can abut against the outer wall 113 to achieve a sealing effect. The groove 115 can be used as an oil storage tank to collect the oil deposited in the air outlet. The upper end of the inner wall 112 is recessed downward to form a notch 116, which serves as an oil guide port. Thus, the oil in the groove 115 can enter the interior of the cover 11 through the oil guide port 116 and be introduced into the oil circuit of the entire range hood.

[0042] To facilitate the relative fixation of the adapter 2 and the air outlet shroud 11, the air outlet shroud assembly 1 includes the aforementioned locking member 12. An insertion hole 117 extending circumferentially along the outer wall 113 of the air outlet shroud 11 is provided. The locking member 12 includes a body 121, a latch 122 formed on the body 121, and a limiting rib 123 formed on the body 121. The body 121 may be a generally sheet-like cuboid. Two latches 122 are formed at one end along the length direction of the body 121 (the insertion direction into the air outlet shroud 11), and the latches 122 have a certain degree of elasticity. The limiting rib 123 extends along the length direction of the body 121, and the latches 122 are located on the upper and lower sides of the limiting rib 123. The latches 122 may be formed by hollowing out the body 121.

[0043] The hood 11 has two stops 118 on its body 111, which are disposed on the outer side of the outer wall 113. Each stop 118 has an L-shaped vertical cross-section, and the two stops 118 are arranged symmetrically vertically. Each stop 118 has a lateral extension 1181 extending outward from the outer wall 113 and a longitudinal extension 1182 extending longitudinally from the end of the lateral extension 1181 away from the outer wall 113. The longitudinal extensions 1182 of the two stops 118 extend towards each other, with the longitudinal extension 1182 of the upper stop 118 extending downward and the longitudinal extension 1182 of the lower stop 118 extending upward. The connector 119 connects the two stops 118. The hood 111, the stops 118, and the connector 119 are preferably integrally formed.

[0044] The insertion hole 117 corresponds between the two stops 118. Thus, the locking member 12 can be inserted between the stops 118 and the outer wall 113. The latch 122 is inserted from one end of the stops 118 and exits from the other end to lock in place. The stops 118 exert a force on the locking member 12, pressing it towards the outer wall 113 and restricting its vertical position. The limiting rib 123, during the insertion of the locking member 12, passes through the insertion hole 117 on the outer wall 113, entering the interior of the outer wall 113 and abutting against the first upper rib 251 of the adapter 2, preventing the adapter 2 from detaching from the air outlet shroud 11, thus achieving a fixing and anti-detachment function. The latch 122 prevents the locking member 12 from falling off the air outlet shroud 11 as a whole.

[0045] During installation, first install the sealing ring 3 onto the adapter 2, then insert the adapter 2 into the groove 115 of the exhaust hood 11 from top to bottom, and finally insert the locking piece 12 to lock the positions of the adapter 2 and the exhaust hood 11. Because the adapter 2 has a full circle of first raised ribs 251, the adapter 2 can be directly inserted into the groove 115 of the exhaust hood 11, thus avoiding the installation difficulties caused by twisting the exhaust pipe 100 and the problem of the exhaust pipe 100 being subjected to torsional stress for a long time, making the whole system more reliable.

[0046] Example 2

[0047] See Figure 10 In this embodiment, the difference from the first embodiment is that a sealing gasket 4 is provided between the bottom of the second connecting part 23 of the adapter 2 and the bottom surface of the groove 115 of the air outlet hood 11. Thus, the sealing ring 3 achieves radial sealing, and the sealing gasket 4 achieves end face sealing. The two achieve double sealing and provide reliable sealing performance.

[0048] Alternatively, only the sealing gasket 4 can be installed without the sealing ring 3.
