When the fan 402 is running, the oil smoke is discharged through the smoke inlet 161, the smoke collecting cavity, the top air vent 19, the inner cavity of the bellows 401, the fan 402 and the smoke exhaust pipe in sequence.

[0045] In the present embodiment, in order to reduce the probability of oil stains inside the bellows 401 dripping downward and falling into the smoke inlet 161, in the present embodiment, the casing assembly 100 also includes an oil receiving pan 2, which is arranged inside the smoke hood 1 and is arranged above the smoke inlet 161 at an interval, and one oil receiving pan 2 is arranged on each of the left and right sides of the top air outlet 19, and the two oil receiving pans 2 extend into the inner side of the top air outlet 19 on opposite sides to each other to receive the oil dripping downward from the left and right walls of the inner cavity of the bellows 401, and the oil receiving pan 2 guides the oil to flow toward the outer side of the smoke inlet 161.

[0046] The casing assembly 100 provided in the present embodiment, by providing an oil receiving pan 2, can receive the oil dripping downward from the inner wall of the bellows 401, and prevent the oil from dripping directly into the smoke collecting chamber and causing the oil droplets to fall downward onto the stove through the smoke inlet 161, thereby preventing the oil from dripping randomly, and better realizing the collection of the oil, thereby improving the user experience of the range hood; furthermore, the oil receiving pan 2 is arranged at intervals on the upper side of the smoke inlet 161 and located on the left and right sides of the top air outlet 19, so that the setting of the oil receiving pan 2 will not cause significant interference to the air intake of the smoke collecting hood 1, thereby ensuring the air intake effect of the range hood using the casing assembly 100.

[0047] The bellows 401 includes two side box walls 4011 arranged opposite to each other in the left and right directions, a front box wall connected between the two side box walls 4011, and a rear box wall connected between the rear sides of the two side box walls 4011. The projection of each box side wall on the horizontal projection plane is located within the projection range of the oil receiving pan 2 on the horizontal projection plane, thereby ensuring that the oil dripping downward from the side box walls 4011 will fall into the oil receiving pan 2, ensuring the oil guiding effect of the oil receiving pan 2.

[0048] like Figures 2 to 4 As shown, in this embodiment, the oil receiving pan 2 extends in the front-to-back direction and both ends are fastened to the fume hood 1. While ensuring the stability and reliability of the setting of the oil receiving pan 2 on the fume hood 1, the overall structural strength and rigidity of the fume hood 1 can be better improved by the oil receiving pan 2, ensuring the relative position accuracy of the hood front plate 11 and the hood back plate 13, thereby being more conducive to ensuring the overall shape accuracy of the housing assembly 100 and improving the support performance of the fume hood 1 for the host module 400. The two ends of the oil receiving pan 2 are preferably detachably connected to the fume hood 1 to facilitate the cleaning and replacement of the oil receiving pan 2.

[0049] The smoke hood 1 includes a hood front plate 11, a hood back plate 13, a hood bottom plate 12, a hood top plate 15 and two hood side plates 14 which enclose a smoke collecting chamber. The hood front plate 11 and the hood back plate 13 are arranged opposite to each other and spaced apart in the front-to-back direction, the hood bottom plate 12 is connected between the lower ends of the hood front plate 11 and the hood back plate 13, and the left and right ends are respectively connected to the two hood side plates 14; the hood top plate 15 is connected to the top of the hood front plate 11 and the hood back plate 13. In this embodiment, two hood top plates 15 are spaced apart in the left-right direction so that a top air outlet 19 is formed between the two hood top plates 15. In other embodiments, the hood top plate 15 can also extend to the two hood side plates 14 in the left-right direction, and the top air outlet 19 is formed on the top hood plate.

[0050] In this embodiment, the upper end of the hood front plate 11 is vertically folded backward to form a top flap portion 17, and the upper surface of the top flap portion 17 is flush with the upper surface of the hood top plate 15. The provision of the top flap portion 17 is conducive to ensuring the flatness of the upper surface of the smoke hood 1 after assembly; at the same time, it also avoids the formation of sharp edges on the front side of the smoke hood 1, which may cause scratches to the user when cleaning the range hood, thereby improving the safety of the range hood.

[0051] The hood front plate 11 and the hood back plate 13 are arranged vertically, so that the housing assembly 100 and the range hood are more aesthetically pleasing as a whole, and are convenient for installing the range hood. The hood bottom plate 12 extends downwardly from front to back to guide the waste oil inside the smoke collecting chamber to flow to the rear side of the smoke collecting chamber. An oil collecting port is arranged at the rear side of the hood bottom plate 12, and an oil cup 300 is installed at the lower end of the hood bottom plate 12, and the waste oil gathered at the rear end of the smoke collecting chamber falls into the oil cup 300 through the oil collecting port.

[0052] The cover bottom plate 12 is integrally formed with a smoke collecting boss 16, which is formed by the local structure of the cover bottom plate 12 being recessed upwards, and the top of the smoke collecting boss 16 is provided with the above-mentioned smoke inlet 161, and the angle between the side wall of the smoke collecting boss 16 and the bottom of the smoke collecting chamber is an obtuse angle, so as to guide the oil on the side wall of the smoke collecting boss 16 to flow to the bottom of the smoke collecting chamber. The concave space of the smoke collecting boss 16 forms a smoke collecting space, so as to better guide the oil smoke into the smoke inlet 161. It is preferred that two smoke collecting bosses 16 are arranged at intervals along the left and right directions, so as to realize double-sided air intake and improve the oil smoke exhaust effect.

[0053] An oil net 500 is provided at each smoke inlet 161 to filter and condense the oil smoke. Furthermore, the range hood further comprises a fixed panel 200 and a flap assembly 600. The fixed panel 200 is installed on the lower surface of the cover bottom plate 12 and extends in the left-right direction. The fixed panel 200 covers the rear area of ​​the smoke collecting space to improve the structural aesthetics of the range hood; the flap assembly 600 is movably installed on the front side of the housing assembly 100 to open or close the smoke inlet 161, and when the flap assembly 600 closes the smoke inlet 161, the flap assembly 600 is flush with the fixed panel 200.

[0054] In order to improve the connection convenience between the front end of the oil receiving pan 2 and the fume collecting hood 1, in this embodiment, the rear end of the top flap portion 17 is folded downward to form a mounting flange portion 18, and the front end of the oil receiving pan 2 is detachably connected to the mounting flange portion 18. As a result, the oil receiving pan 2 can be fixedly installed below the hood top plate 15 to avoid interference between the oil receiving pan 2 and the hood top plate 15.

[0055] In this embodiment, the installation flange portion 18 includes a vertically connected transverse flange portion 182 and a vertical flange portion 181. The vertical flange portion 181 is vertically arranged and connected between the rear end of the top flap portion 17 and the front side of the transverse flange portion 182. The front end of the oil receiving pan 2 is supported on the transverse flange portion 182 and connected to the transverse flange portion 182. Therefore, the height of the vertical flange portion 181 can increase the distance between the oil receiving pan 2 and the cover top plate 15, thereby further reducing the interference between the oil receiving pan 2 and the cover top plate 15.

[0056] The cover top plate 15 includes a rectangular top main plate portion 151, and the four sides of the top main plate portion 151 are folded downward to form a top plate flange 152, wherein the top main plate portion 151 is in contact with the top flap portion 17, the top plate flange 152 located at the rear side cooperates with the cover back plate 13, and the top plate flange 152 located on the side away from the top air outlet 19 is in contact with the cover side plate 14. The top plate flange 152 located at the front side of the top main plate portion 151 is sandwiched between the vertical flange portion 181 and the front end of the oil receiving pan 2. Preferably, an insertion hole is opened on the vertical flange portion 181, and the lower end of the top plate flange 152 on the front side extends forward to have an inserting plate portion 153, which is inserted into the insertion hole.

[0057] The hood back plate 13 is punched from back to front to form a rear pressure profile 131, and the rear end of the oil receiving pan 2 is detachably connected to the rear pressure profile 131, so that the end of the connecting piece between the rear end of the oil receiving pan 2 and the rear pressure profile 131 can be hidden in the groove formed on the rear side of the rear pressure profile 131, avoiding the connecting piece protruding backward from the hood back plate 13 and affecting the installation of the range hood.

[0058] like Figures 4 to 6 As shown, in this embodiment, the oil receiving pan 2 includes an oil receiving plate portion 21, which is arranged below the cover top plate 15 at intervals and receives oil drops dripping downward from the inner wall of the fan 402 box. The oil receiving plate portion 21 has a first side close to another oil receiving pan 2 and a second side opposite to the first side, the first side is located on the inner side of the top air port 19, and the second side is staggered with the smoke inlet 161 in the left and right directions, so that when the oil receiving plate portion 21 can receive the oil dripping from the inner wall of the fan 402 box, the oil on the oil receiving plate portion 21 will not directly drip to the smoke inlet 161.

[0059] In this embodiment, the oil receiving plate portion 21 has a tendency to tilt downward from front to back, so that the oil receiving plate portion 21 guides the oil thereon to flow to the rear side of the smoke collecting chamber, and then flows into the oil cup 300 through the oil collecting port at the bottom of the smoke collecting chamber. In other embodiments, the oil receiving plate portion 21 has a tendency to tilt downward from the first side to the second side, so as to guide the oil on the oil receiving pan 2 to the side edge of the smoke collecting chamber, and then guide the oil to the oil collecting port through the bottom of the smoke collecting chamber.

[0060] It is worth noting that the oil receiving plate portion 21 has a tendency to tilt downward from front to back, which means that the oil receiving plate portion 21 is tilted downward from front to back as a whole, or the oil receiving plate portion 21 is partially tilted downward from front to back, and the other parts of the oil receiving plate portion 21 are arranged horizontally.

[0061] The front end of the oil receiving plate portion 21 is connected to a front mounting portion 24, which is connected to the mounting flange portion 18. The front mounting portion 24 is preferably configured as a horizontal plate-like structure so that the front mounting portion 24 can fit the upper surface of the transverse flange portion 182. The rear end of the oil receiving plate portion 21 is connected to a rear mounting portion 25, which is connected to the rear pressure profile 131. The rear mounting portion 25 is preferably a plate-like structure folded downward from the rear end of the oil receiving plate portion 21 to reduce the difficulty of processing the oil receiving pan 2.

[0062] In order to reduce the problem that the oil on the oil receiving pan 2 flows to the mounting flange 18 and then causes the oil to seep upward from the top of the smoke collecting hood 1, in this embodiment, an oil leakage port 212 is provided at the rear end of the oil receiving plate portion 21 to guide the waste oil on the oil receiving plate portion 21 to flow downward to the rear side of the smoke collecting chamber through the oil leakage hole, thereby preventing the oil from accumulating at the connection between the oil receiving pan 2 and the mounting flange 18. The projection of the oil leakage port 212 on the horizontal projection plane is located on the rear side of the projection of the smoke inlet 161 on the horizontal projection plane. In other embodiments, an oil leakage port 212 may also be formed between the rear end of the oil receiving plate portion 21 and the smoke collecting hood 1.

[0063] Furthermore, in this embodiment, the front mounting portion 24 is arranged higher than the oil receiving plate 21, that is, the front mounting portion 24 is connected to the oil receiving plate portion 21 through the bending portion, thereby preventing the oil from flowing out of the front mounting portion 24, further preventing the oil from flowing to the front mounting portion 24 and the mounting flange portion 18, and ensuring that the oil at the oil receiving plate portion 21 can flow downward through the oil leakage port 212. Preferably, at least two oil leakage ports 212 are arranged at intervals in the left-right direction to ensure the oil drainage effect at the oil receiving plate portion 21.

[0064] In this embodiment, the oil receiving plate portion 21 includes a plurality of sub-plate portions 211 that are bent and connected in sequence from front to back, and the height of the plurality of sub-plate portions 211 gradually decreases from front to back, thereby facilitating the oil on the oil receiving plate portion 21 to flow toward the rear end of the oil receiving plate portion 21, promoting the discharge of the oil, and also reducing the structural interference between the oil receiving plate portion 21 and the smoke collecting boss 16. Preferably, at least part of the sub-plate portion 211 extends obliquely downward from front to back. In other embodiments, the oil receiving plate portion 21 may extend obliquely downward from front to back as a whole.

[0065] In order to further reduce the possibility of oil flowing toward the smoke inlet 161, in the present embodiment, the oil receiving plate portion 21 is upwardly connected to the side facing the top air outlet 19 with a side oil baffle plate portion 22, and the side oil baffle plate portion 22 is used to stop the oil on the oil receiving plate portion 21 from dripping downward through its edge close to the top air outlet 19, thereby improving the oil blocking effect.

[0066] like Figure 7 and Figure 8 As shown, the second side of the oil receiving plate portion 21 is connected to the oil guide plate portion 23, and the oil guide plate portion 23 extends downwardly obliquely away from the first side of the oil receiving plate portion 21 to reduce the distance between the lowermost end of the oil receiving pan 2 and the bottom of the smoke collecting chamber, and guide the oil to flow downward along the oil guide plate portion 23 to the bottom of the smoke collecting chamber, thereby preventing the oil droplets dripping downward from the second side of the oil receiving plate portion 21 from splashing to other positions due to the high dripping distance, thereby improving the reliability of oil recovery.

[0067] Furthermore, the lower end of the oil guide plate portion 23 is arranged opposite to the side of the smoke collecting boss 16 to guide the oil to the inner wall of the smoke collecting boss 16, and then the inner wall of the smoke collecting boss 16 guides the oil to flow to the rear end bottom of the smoke collecting chamber, further improving the oil drainage effect.

[0068] In this embodiment, in order to improve the supporting performance of the housing assembly 100 for the host module 400, in this embodiment, the housing assembly 100 includes a top support member 3, which is installed on the oil receiving pan 2 and at least partially located on the inner side of the top air outlet 19, and the bellows 401 is fastened to the top support member 3 and the cover top plate 15. This arrangement allows part of the gravity of the host module 400 to be shared to the cover top plate 15, and part of the gravity to be shared to the top support member 3, so as to ensure the installation stability of the host module 400 on the housing assembly 100; by providing the top support member 3, the local structural strength and rigidity of the connection between the housing assembly 100 and the host module 400 can also be enhanced, the probability of deformation due to stress at the connection can be reduced, the overall structural strength and rigidity of the housing assembly 100 can be enhanced, and the installation stability of the host module 400 on the housing assembly 100 can be improved.

[0069] In this embodiment, the top support member 3 is a long strip structure extending in the front-to-back direction, so as to realize the connection between the top reinforcement member and the bellows 401 while reducing the width of the top support member 3 in the left-right direction, reducing the weight of the top reinforcement member and reducing the cost. Preferably, the top support member 3 includes a horizontal connection part and a vertical connection part, the horizontal connection part is attached to the surface of the oil receiving pan 2 and connected to the oil receiving pan 2, and the vertical connection part is vertically arranged. The side box wall 4011 is connected to the vertical connection part. This structural arrangement of the top support member 3 can improve the structural stability of the top support member 3, the oil receiving pan 2 and the bellows 401.

[0070] In this embodiment, the side box wall 4011 is located between the top plate flange 152 and the vertical connection portion on the side facing the top air outlet 19, and the vertical connection portion, the side box wall 4011 and the top plate flange 152 are fastened by fasteners penetrating the three.

[0071] Preferably, the transverse connecting portion is welded to the oil receiving pan 2 to avoid oil leakage caused by opening a hole or groove structure on the oil receiving pan 2 to connect to the top support member 3, thereby ensuring the oil guiding effect of the oil receiving pan 2; at the same time, the welding of the oil receiving pan 2 and the top support member 3 can enhance the overall structural strength and rigidity of the casing assembly 100, and improve the supporting performance of the casing assembly 100.
