For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] As described in the background art, the range hood in the related art has the problem of cumbersome procedures for disassembling the transmission structure. The inventor has found through research that the reason for this problem is that the transmission structure is connected to the bracket, the rear end of the bracket is in contact with the back plate of the shell, and the fastening bolts pass through the back plate and the bracket in sequence from the outside of the back plate to fix the bracket to the back plate. When the transmission structure needs to be disassembled, the bracket needs to be removed from the back plate, that is, the fastening bolts fixing the back plate and the bracket need to be loosened from the outside of the back plate, and because the back plate is against the wall, the entire shell needs to be removed from the wall to loosen the fastening bolts, resulting in cumbersome procedures for disassembling the transmission structure of the range hood.

[0055] In view of the above technical problems, an embodiment of the present application provides a range hood, wherein a reinforcement is arranged between the back plate of the shell and the bracket, the protrusion on the reinforcement and the back plate form a receiving cavity, the rear end of the bracket is connected to the protrusion through a first fastener, the first fastener is sequentially inserted through the bracket and the protrusion, and the rear end of the first fastener is received in the receiving cavity. When the bracket needs to be disassembled, the fastening bolts can be loosened from the inside of the shell, thereby removing the bracket from the reinforcement, without removing the entire shell from the wall, simplifying the procedure for removing the bracket.

[0056] The principles and features of the embodiments of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the embodiments of the present application and are not used to limit the scope of the embodiments of the present application.

[0057] refer to Figure 1-Figure 4 The range hood provided in the embodiment of the present application includes a shell 1, a baffle assembly 5, a reinforcement 2 and a bracket 3.

[0058] The housing 1 may have a smoke inlet side 12, and the smoke inlet side 12 may define a smoke inlet port 121. Exhaust gas from the stove combustion and oil smoke and other gases generated during cooking enter the housing 1 from the smoke inlet port 121 and are discharged by the range hood to a public flue or an outdoor environment, so as to reduce the amount of exhaust gas and oil smoke in the kitchen environment and improve the air quality of the kitchen.

[0059] The baffle assembly 5 is rotatably connected to the housing 1 to open or cover the smoke inlet 121 .

[0060] The rear end of the housing 1 has a back plate 11, and the back plate 11 is used to face the wall.

[0061] The reinforcement member 2 may be a reinforcement plate, the reinforcement member 2 is disposed in the housing 1, and the reinforcement member 2 is disposed on the inner side of the back plate 11. The reinforcement member 2 and the back plate 11 may be connected by fastening bolts 213, and the fastening bolts 213 may be sequentially passed through the back plate 11 and the reinforcement member 2 from the outer side of the back plate 11 to fix the back plate 11 and the reinforcement member 2 in connection.

[0062] A protrusion 21 is configured on the reinforcement member 2 . The protrusion 21 protrudes in a direction away from the back plate 11 . The protrusion 21 and the back plate 11 form a receiving cavity 211 .

[0063] refer to Figure 5 and Figure 6 The transmission structure 4 is movably connected to the bracket 3 , and the transmission structure 4 is also hinged to the baffle assembly 5 . The transmission structure 4 drives the baffle assembly 5 to rotate relative to the housing 1 to open or cover the smoke inlet 121 .

[0064] The transmission structure 4 may include a first rod 41 and a second rod 42 , the first rod 41 and the second rod 42 are hinged, one end of the first rod 41 away from the second rod 42 may be hinged to the bracket 3 , and one end of the second rod 42 away from the first rod 41 may be hinged to the baffle assembly 5 .

[0065] refer to Figure 3 and Figure 4 The bracket 3 is disposed in the housing 1 , and the rear end of the bracket 3 is connected to the protrusion 21 through a first fastener 32 . The first fastener 32 may be a fastening bolt or other component that can fix the bracket 3 and the protrusion 21 .

[0066] The rear end of the bracket 3 may have a flange 31, which may extend upward, and the flange 31 and the protrusion 21 are connected by a first fastener 32. The first fastener 32 may be sequentially inserted through the flange 31 and the protrusion 21, and the end of the first fastener 32 is accommodated in the accommodating cavity 211.

[0067] When the transmission structure 4 is damaged, it is necessary to repair or replace the transmission structure 4. Since the transmission structure 4 is connected to the bracket 3, when the transmission structure 4 needs to be repaired or replaced, the bracket 3 can be removed to facilitate the repair or replacement of the transmission structure 4.

[0068] When disassembling the bracket 3, since the head of the first fastener 32 is located inside the shell 1, when the bracket 3 needs to be disassembled, the first fastener 32 can be loosened from the inside of the shell 1, thereby removing the bracket 3 from the protrusion 21 without removing the entire shell 1 from the wall, thereby simplifying the procedure for disassembling the bracket 3.

[0069] In the range hood of this embodiment, the transmission structure 4 is connected to the bracket 3, and a reinforcement member 2 is arranged between the back plate 11 of the housing 1 and the bracket 3. The protrusion 21 on the reinforcement member 2 and the back plate 11 form a receiving cavity 211. The rear end of the bracket 3 is connected to the protrusion 21 through a first fastener 32. The first fastener 32 is sequentially inserted through the bracket 3 and the protrusion 21, and the rear end of the first fastener 32 is received in the receiving cavity 211. Through the above arrangement, when the transmission structure 4 needs to be repaired or replaced, the bracket 3 can be removed first. When removing the bracket 3, the fastening bolts can be loosened from the inside of the housing 1, so that the bracket 3 can be removed from the reinforcement member 2, without removing the entire housing 1 from the wall, simplifying the procedure for removing the bracket 3 and facilitating the repair or replacement of the transmission structure 4.

[0070] In some possible implementations of the present application, reference is made to Figure 5 and Figure 7 The shell 1 may define an oil fume chamber 13 and assembly chambers 14 located on both sides of the oil fume chamber 13. The oil fume chamber 13 and the assembly chamber 14 are independently arranged. The oil fume chamber 13 is connected to the smoke inlet 121. Oil fume and other gases enter the oil fume chamber 13 from the smoke inlet 121 and are discharged by the range hood into a public flue or an outdoor environment.

[0071] The assembly chamber 14 is located at two sides of the oil fume chamber 13 . The assembly chamber 14 and the oil fume chamber 13 are independently arranged, so that oil fume and other gases are not easy to enter the assembly chamber 14 .

[0072] The reinforcement 2, bracket 3 and transmission structure 4 are all arranged in the assembly cavity 14, which reduces the amount of oil attached to the reinforcement 2, bracket 3 and transmission structure 4, thereby reducing the need to clean the reinforcement 2, bracket 3 and transmission structure 4. The amount of oil attached to the reinforcement 2, bracket 3 and transmission structure 4 is reduced, which reduces the corrosion of the reinforcement 2, bracket 3 and transmission structure 4 by the oil, thereby extending the service life of the reinforcement 2, bracket 3 and transmission structure 4.

[0073] In some possible implementations of the present application, reference is made to Figure 2 , Figure 3 , Figure 4 and Figure 6 The housing 1 may have a detachable top plate 15 , and the top plate 15 covers the top of the assembly cavity 14 .

[0074] After the top plate 15 is removed from the top of the housing 1 , the assembly cavity 14 can be exposed, thereby facilitating the disassembly of the first fastener 32 and the bracket 3 .

[0075] In some possible implementations of the present application, reference is made to Figure 4The accommodating cavity 211 may have an operation opening 212, and the accommodating cavity 211 and the assembly cavity 14 are connected through the operation opening 212. The first fastener 32 can be easily removed from the reinforcement 2 and the bracket 3 through the operation opening 212. Exemplarily, when it is difficult to remove the first fastener 32 from the head of the first fastener 32, a disassembly tool can be inserted into the accommodating cavity 211 from the operation opening 212 to assist in disassembling the first fastener 32, so as to facilitate the removal of the first fastener 32 from the reinforcement 2 and the bracket 3.

[0076] In some possible implementations of the present application, reference is made to Figure 4 The operation port 212 may be located at the top of the accommodating cavity 211. After the top plate 15 is removed, since the operation port 212 faces upward, it is convenient to control the first fastener 32 in the accommodating cavity 211 from top to bottom, thereby facilitating the disassembly of the first fastener 32 and the bracket 3.

[0077] In some possible implementations of the embodiments of the present application, the operating port 212 can be located on the side of the accommodating cavity 211. As long as the first fastener 32 can be controlled from the top of the assembly cavity 14 and the operating port 212, it is convenient to disassemble the first fastener 32 and the bracket 3.

[0078] In some possible implementations of the present application, reference is made to Figure 1-Figure 3 , Figure 5 and Figure 7 The range hood may include a main box body 6 , which is disposed on the top of the housing 1 , and the main box body 6 is connected to the oil fume chamber 13 .

[0079] The main box body 6 may be configured with a smoke outlet 61, and the smoke outlet 61 is used to communicate with a public flue or an outdoor environment through a smoke exhaust pipe.

[0080] The range hood may include a fan 7 , which is disposed in the main box 6 .

[0081] When the fan 7 is working, a negative pressure is formed at the smoke inlet 121, and the exhaust gas from the combustion of the stove and the oil smoke and other gases generated during the cooking process enter the oil smoke chamber 13 through the smoke inlet 121. The oil smoke and other gases in the oil smoke chamber 13 enter the main box body 6 and flow to the smoke outlet 61 under the action of the fan 7, and are discharged from the smoke outlet 61, so as to reduce the amount of exhaust gas and oil smoke in the kitchen environment and improve the air quality of the kitchen.

[0082] refer to Figure 3 , Figure 6 and Figure 7The shell 1 may have a front baffle 16, which extends from the smoke inlet side 12 in a direction away from the back plate 11. The main box body 6 is located above part of the front baffle 16. The front end of the bracket 3 can be detachably connected to the front baffle 16 through a second fastener 33 to improve the reliability of the connection between the bracket 3 and the shell 1.

[0083] The second fastener 33 may be a fastening bolt or other component that can fix the bracket 3 and the front baffle 16 .

[0084] In some possible implementations of the present application, reference is made to Figure 2 , Figure 3 and Figure 6 The top plate 15 covers the front baffle 16 outside the main box body 6 to cover the front baffle 16, thereby improving the decorative effect of the range hood.

[0085] In some possible implementations of the embodiments of the present application, the range hood may include a driving device, which is disposed in the assembly cavity 14 . The driving device drives the transmission structure 4 to rotate, and the transmission structure 4 drives the baffle assembly 5 to open or cover the smoke inlet 121 .

[0086] By driving the transmission structure 4 to rotate through the driving device, it is easier to realize that the transmission structure 4 drives the baffle assembly 5 to rotate.

[0088] In some possible implementations of the embodiments of the present application, the driving device may include a driving motor and a driving gear. When the driving motor is working, the driving gear rotates, the transmission structure 4 meshes with the driving gear and rotates with the driving gear, and the transmission structure 4 drives the baffle assembly 5 to open or cover the smoke inlet 121 during the rotation process.

[0089] In some possible implementations of the present application, reference is made to Figure 6 The baffle assembly 5 may include a baffle 51 , a hinge 52 and a fixing member 53 , and the hinge 52 and the fixing member 53 are both connected to the inner side of the baffle 51 .

[0091] The fixing member 53 is further away from the top of the baffle 51 than the hinge 52 . The transmission structure 4 is hinged to the fixing member 53 . The transmission structure 4 is used to move the bottom end of the baffle 51 toward or away from the smoke inlet side 12 , thereby opening or covering the smoke inlet port 121 .
