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.

[0050] 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.

[0051] 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.

[0052] refer to Figure 1 and Figure 2 The range hood provided in the embodiment of the present application includes a shell 1 and a baffle assembly 2.

[0053] The housing 1 may have a smoke inlet side 11, and the smoke inlet side 11 may define a smoke inlet port 12. Exhaust gas from the stove combustion and oil smoke and other gases generated during cooking enter the housing 1 from the smoke inlet port 12 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.

[0054] The baffle assembly 2 is rotatably connected to the housing 1 to open or cover the smoke inlet 12 .

[0055] When the range hood is in the off state, the baffle assembly 2 blocks the smoke inlet 12, thereby improving the decorative effect of the range hood.

[0056] refer to Figure 2 When the range hood is working, the baffle assembly 2 rotates relative to the shell 1, and the bottom end of the baffle assembly 2 moves away from the shell 1 to open the smoke inlet 12, so that oil smoke and other gases can enter the shell 1 from the smoke inlet 12 and be discharged by the range hood.

[0057] The range hood may include an oil cup 4 , which may be disposed at the bottom of the housing 1 , and is used to collect oil flowing down from the inner wall of the housing 1 .

[0058] When the range hood is sucking in oil smoke and other gases, some oil droplets in the oil smoke and other gases will adhere to the inner wall of the shell 1 and the inner wall of the baffle assembly 2. As the amount of attached oil droplets gradually increases, the oil droplets will converge into an oil flow and flow downward to the oil cup 4 to be collected.

[0059] refer to Figure 3 and Figure 4 The baffle assembly 2 includes a baffle 21 and a rear shell 22, and the rear shell 22 is arranged on the inner side of the baffle 21. The rear shell 22 and at least a part of the baffle 21 surround an electric control chamber 23.

[0060] The range hood may include a controller 3, which is disposed in the electric control chamber 23. Compared with disposing the controller 3 at other locations of the range hood, the space occupied by the controller 3 is saved. The baffle 21 may be provided with a touch area or a control button, and the controller 3 is controlled by the touch area or the control button to realize the function selection of the range hood.

[0061] The rear housing 22 includes a rear plate 221 and a bottom plate 222 . The rear plate 221 is disposed opposite to the baffle 21 . One end of the bottom plate 222 is connected to the bottom end of the rear plate 221 , and the other end of the bottom plate 222 is connected to the baffle 21 .

[0062] When the baffle assembly 2 blocks the smoke inlet 12, that is, when the range hood is in the off state, the bottom end of the rear plate 221 is located in the smoke inlet 12, that is, the bottom end of the rear plate 221 extends into the shell 1, so that when the oil droplets on the rear plate 221 flow downward to the bottom end of the rear plate 221, they will continue to flow downward into the shell 1 and be collected in the oil cup 4, so that the oil on the rear plate 221 is not easy to drip from the bottom end of the rear plate 221 onto the kitchen countertop.

[0063] When the baffle assembly 2 blocks the smoke inlet 12, at least one end of the bottom plate 222 is located in the smoke inlet 12, and the bottom plate 222 is tilted upward in a direction away from the smoke inlet 12, that is, the bottom plate 222 is tilted upward from one end close to the rear plate 221 to one end close to the baffle 21, that is, the height of one end of the bottom plate 222 close to the rear plate 221 is lower than the height of one end of the bottom plate 222 close to the baffle 21. With such a configuration, on the one hand, it is difficult for the oil flowing downward along the rear plate 221 to the bottom end of the rear plate 221 to flow onto the bottom plate 222; on the other hand, the oil droplets attached to the surface of the bottom plate 222 can flow downward along the tilted bottom plate 222 to the bottom end of the rear plate 221, and flow downward from the bottom end of the rear plate 221 into the housing 1, and finally be collected in the oil cup 4, so that the oil droplets on the bottom plate 222 are not easy to drip onto the kitchen countertop.

[0064] In the range hood of this embodiment, when the baffle assembly 2 blocks the smoke inlet 12, the bottom end of the rear plate 221 extends into the shell 1, so that the oil droplets on the rear plate 221 flow downward into the shell 1; by making the bottom plate 222 tilt upward from one end close to the rear plate 221 to the other end close to the baffle 21, it is difficult for the oil flowing downward along the rear plate 221 to the bottom end of the rear plate 221 to flow onto the bottom plate 222, and the oil droplets attached to the surface of the bottom plate 222 can flow downward along the tilted bottom plate 222 and drip into the shell 1, so that the oil droplets on the rear plate 221 and the bottom plate 222 are guided into the shell 1 and finally collected in the oil cup 4, so that the oil droplets on the inner wall of the baffle assembly 2 are not easy to drip onto the kitchen countertop.

[0065] In some possible implementations of the present application, reference is made to Figure 4 The rear shell 22 may have a top plate 224 , one end of the top plate 224 is connected to the top end of the rear plate 221 , and the other end of the top plate 224 is connected to the baffle 21 .

[0066] When the baffle assembly 2 blocks the smoke inlet 12, at least one end of the top plate 224 is located in the smoke inlet 12, and the top plate 224 is inclined upward in a direction away from the smoke inlet 12, that is, the top plate 224 is inclined downward from an end close to the baffle 21 to an end close to the rear plate 221, that is, the height of the end of the top plate 224 close to the baffle 21 is higher than the height of the end of the top plate 224 close to the rear plate 221. The inclined top plate 224 can guide the oil, and the oil droplets on the surface of the top plate 224 and the oil droplets flowing to the top plate 224 along the baffle 21 above the top plate 224 can flow downward along the inclined top plate 224 to the top of the rear plate 221, and flow downward along the rear plate 221 into the shell 1, and finally be collected by the oil cup 4.

[0067] In some possible implementations of the present application, reference is made to Figure 4 The rear shell 22 may have two opposite side plates 225, and the top plate 224, the bottom plate 222 and the two side plates 225 are arranged around the periphery of the rear plate 221 to form a rear shell 22 with an opening. The baffle 21 blocks the opening of the rear shell 22 and forms an electric control chamber 23 with the rear shell 22, so that gas such as oil smoke and oil droplets are not easy to flow into the electric control chamber 23, thereby protecting the controller 3 in the electric control chamber 23.

[0068] refer to Figure 4 , Figure 5 and Figure 6 The baffle assembly 2 may include a shielding member 24, which shields the outer side of the side panel 225 so that the user cannot easily observe the side panel 225 and the rear shell 22, thereby improving the decorative effect of the range hood.

[0069] In some possible implementations of the embodiments of the present application, the shielding member 24 may be a shielding plate or a shielding sheet, etc.

[0070] In some possible implementations of the present application, reference is made to Figure 5 , Figure 7 ,, Figure 8 and Fig. 9 The bottom end of the shielding member 24 may have a flange 241 extending toward the rear housing 22, and the flange 241 is located at the bottom of the bottom plate 222. The flange 241 may be configured with a first connection hole 242, and the bottom plate 222 may be configured with a second connection hole 223. The flange 241 and the bottom plate 222 may be connected by fastening bolts 243 passing through the first connection hole 242 and the second connection hole 223.

[0071] In some possible implementations of the present application, reference is made to Figure 7 and Fig. 9 The flange 241 may be constructed with a boss 244, which protrudes toward the bottom plate 222. The first connecting hole 242 is constructed at one end of the boss 244 close to the bottom plate 222 to increase the distance between the first connecting hole 242 and the flange 241, so that the oil on the side of the flange 241 away from the bottom plate 222 is not easy to flow through the first connecting hole 242 to between the flange 241 and the bottom plate 222.

[0072] In some possible implementations of the present application, reference is made to Figure 6 The bottom end of the shielding member 24 can extend to the bottom plate 222, and the top end of the shielding member 24 can extend to the top end of the baffle 21. That is to say, the shielding member 24 extends from the bottom end of the side plate 225 to the top end of the baffle 21 to shield the entire side plate 225 and the area between the top end of the side plate 225 and the top end of the baffle 21, so that the rear shell 22 and the stepped structure formed by the rear plate 221, the top plate 224 and the baffle 21 are not easily observed from both sides of the baffle assembly 2, thereby improving the decorative effect of the range hood.

[0073] In some possible implementations of the present application, reference is made to Figure 5 A limiting portion 245 may be provided on the side of the shielding member 24 facing the side panel 225, and the side panel 225 is constructed with a matching portion. The limiting portion 245 and the matching portion cooperate with each other and limit the side panel 225 from moving downward and away from the shielding member 24 relative to the shielding member 24, thereby improving the stability of the connection between the shielding member 24 and the side panel 225.

[0074] In some possible implementations of the embodiments of the present application, when the limiting portion 245 and the matching portion cooperate with each other, the first connection hole 242 on the flange 241 or the boss 244 corresponds to the second connection hole 223 on the bottom plate 222 .

[0075] When the shielding member 24 is installed with the rear housing 22 , the limiting portion 245 and the matching portion cooperate with each other to position the shielding member 24 and the side plate 225 , so as to facilitate passing the fastening bolts 243 through the first connecting hole 242 and the second connecting hole 223 .

[0076] In some possible implementations of the present application, reference is made to Figure 5 and Figure 7 The limiting portion 245 may include a first portion 246 and a second portion 247 , the first portion 246 is connected to the shielding member 24 , the second portion 247 is disposed on the top of the first portion 246 , and an insertion gap 248 is provided between the second portion 247 and the shielding member 24 .

[0077] refer to Figure 5 and Figure 8 The mating portion includes a limiting hole 226. After the limiting portion 245 is inserted into the limiting hole 226, the shielding member 24 is moved upward so that part of the side panel 225 is inserted into the insertion gap 248. At this time, the side panel 225 is not easy to move downward relative to the shielding member 24, and the side panel 225 is inserted into the insertion gap 248, so that the side panel 225 is not easy to move away from the shielding member 24, thereby positioning the side panel 225 and the shielding member 24.

[0078] In some possible implementations of the present application, reference is made to Figure 8 , Fig. 9 and Fig.10 The limiting hole 226 may include a first hole segment 227, a transition hole segment 228 and a second hole segment 229 arranged in sequence from bottom to top, the length of the first hole segment 227 along the thickness direction X of the limiting portion 245 is greater than the length of the second hole segment 229 along the thickness direction X, and the length of the transition hole segment 228 along the thickness direction X gradually decreases from one end close to the first hole segment 227 to one end close to the second hole segment 229.

[0079] When the shielding member 24 and the side plate 225 are installed, the length of the first hole section 227 along the thickness direction X of the limiting portion 245 is relatively large, so the limiting portion 245 can easily pass through the first hole section 227 .

[0080] After the limiting portion 245 passes through the first hole section 227 , it moves upward along the transition hole section 228 and is locked in the second hole section 229 .

[0081] The length of the second hole segment 229 along the thickness direction X of the limiting portion 245 is smaller than the length of the first hole segment 227 along the thickness direction X of the limiting portion 245. Exemplarily, the length of the second hole segment 229 along the thickness direction X of the limiting portion 245 may be equal to or slightly larger than the length of the thickness direction X of the limiting portion 245. After the limiting portion 245 is inserted into the first hole segment 227, the swing amplitude of the limiting portion 245 along the thickness direction X of the limiting portion 245 may be reduced, thereby improving the stability of the connection between the shielding member 24 and the side plate 225.

[0082] The length of the end of the transition hole section 228 close to the first hole section 227 along the thickness direction X of the limiting portion 245 may be equal to the length of the first hole section 227 along the thickness direction X of the limiting portion 245. The length of the end of the transition hole section 228 close to the second hole section 229 along the thickness direction X of the fiber cloth may be equal to the length of the second hole section 229 along the thickness direction X of the limiting portion 245. The transition hole section 228 transitions the lengths of the first hole section 227 and the second hole section 229 along the thickness direction X of the limiting portion 245, thereby improving the smoothness of the sliding of a portion of the limiting portion 245 from the first hole section 227 into the second hole section 229.

[0083] In some possible implementations of the embodiments of the present application, the limiting portion 245 may include a first column and a second column, one end of the first column is connected to the shielding member 24, the bottom end of the second column is connected to an end of the first column away from the shielding member 24, and there is an insertion gap 248 between the second column and the shielding member 24.

[0084] The matching portion may include a matching tube disposed on a side of the side plate 225 facing the shielding member 24 , and an axis of the matching tube is parallel to an axis of the second column.

[0085] When installing the shielding member 24 and the rear shell 22, the second column is inserted into the matching hole from bottom to top, and the tube wall of the partial matching tube is inserted in the insertion gap 248. At this time, the side panel 225 is not easy to move downward relative to the shielding member 24, and the tube wall of the partial matching tube is inserted in the insertion gap 248, so that the side panel 225 is not easy to move away from the shielding member 24, thereby positioning the side panel 225 and the shielding member 24.

[0086] To summarize, the range hood of the embodiment of the present application includes a shell body 1 and a baffle assembly 2, the shell body 1 defines a smoke inlet 12, and the baffle assembly 2 is rotatably connected to the shell body 1 to open or cover the smoke inlet 12; the baffle assembly 2 includes a baffle 21 and a rear shell 22, the rear shell 22 is arranged on the inner side of the baffle 21, the rear shell 22 has a rear plate 221 and a bottom plate 222, the rear plate 221 is arranged opposite to the baffle 21, one end of the bottom plate 222 is connected to the bottom end of the rear plate 221, and the other end of the bottom plate 222 is connected to the baffle 21; when the baffle assembly 2 covers the smoke inlet 12, the bottom end of the rear plate 221 extends into the shell body 1, and the bottom plate 222 is inclined upward from one end close to the rear plate 221 to one end close to the baffle 21. Through the above arrangement, when the baffle assembly 2 blocks the smoke inlet 12, the bottom end of the rear plate 221 extends into the shell body 1, so that the oil droplets on the rear plate 221 flow downward into the shell body 1; the bottom plate 222 is inclined upward from one end close to the rear plate 221 to the other end close to the baffle 21, so that the oil flowing downward along the rear plate 221 to the bottom end of the rear plate 221 is difficult to flow onto the bottom plate 222, and the oil droplets attached to the surface of the bottom plate 222 can flow downward along the inclined bottom plate 222 and drip into the shell body 1, and the oil droplets on the rear plate 221 and the bottom plate 222 are guided into the shell body 1 and finally collected in the oil cup 4, so that the oil droplets on the inner wall of the baffle assembly 2 are not easy to drip onto the kitchen countertop.
