DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , an exhaust hood with automatic oil fume separation, which includes a hood body 1. An inner chamber 2 is opened at the bottom end of the hood body 1. A fan device 3 is installed at the top end of the hood body 1. The fan device 3 passes through the hood body 1 downward and is located inside the inner chamber 2. A separation mechanism for separating oil fume is arranged in the inner chamber 2. The separation mechanism includes a condensation plate 4 and an air-cooled circulation device 5. Four semi-circular fixing blocks 6 are fixed on the side wall of the inner chamber 2 near the rear side. The four semi-circular fixing blocks 6 are divided into two groups and are distributed up and down. The condensation plate 4 is arranged inside the inner chamber 2 and below the fan device 3. A baffle 7 is arranged below the condensation plate 4 in the inner chamber 2. Two fixing columns 8 are fixed at one end of the condensation plate 4 and the baffle 7 close to the semi-circular fixing blocks 6. The fixing column 8 is rotatably connected to the semi-circular fixing block 6 at the corresponding position. The baffle 7 is fixed on the hood body 1 through a fixing mechanism. A plurality of ventilation openings 9 are opened on both the condensation plate 4 and the baffle 7. An air circulation groove 10 is opened inside the condensation plate 4. The air-cooled circulation device 5 is fixed at the top end of the hood body 1. Both ends of the air-cooled circulation device 5 are communicated with a connecting pipe 11. The connecting pipe 11 passes through the hood body 1 downward and is connected to the condensation plate 4. The two connecting pipes 11 are respectively communicated with both ends of the air circulation groove 10.

[0022] When this exhaust hood is in use, the fan device 3 is started to drive the air flow. The oil fume below the exhaust hood is inhaled into the inner chamber 2 through the ventilation openings 9 on the baffle 7, and then inhaled into the fan device 3 through the ventilation openings 9 on the condensation plate 4 and discharged into the external air. At the same time, the air-cooled circulation device 5 is started. The air-cooled circulation device 5 is communicated with the air circulation groove 10 through the connecting pipe 11, so as to continuously input cold air into the air circulation groove 10 and continuously circulate to ensure that the surface temperature of the condensation plate 4 is always lower than the temperature of the oil fume. When the oil fume contacts the condensation plate 4, the temperature is reduced, and the oil in the oil fume is condensed and adheres to the surface of the condensation plate 4. The flue gas is discharged under the action of the fan device 3. The oil adhering to the bottom end of the condensation plate 4 drips onto the baffle 7 under the action of gravity. The oil at the top end of the condensation plate 4 flows due to accumulation. Since the condensation plate 4 and the baffle 7 are inclined, the oil flows under the action of gravity and is collected centrally.

[0023] In actual use, it is found that when cleaning the exhaust hood, it is not easy to disassemble the baffle 7 for internal cleaning. To solve the above problems, in this embodiment, the fixing mechanism includes a cross-shaped chute 12 and a clamping block 13. The cross-shaped chute 12 is opened on both sides of the bottom end of the hood body 1 where the baffle 7 is located. The clamping block 13 is adapted to and slidably connected with the cross-shaped chute 12. The clamping block 13 contacts the baffle 7, and the clamping block 13 is fixed to the cross-shaped chute 12 by a bolt 14.

[0024] In actual use, it is found that oil adheres to the surfaces of the condensation plate 4 and the baffle 7 and will flow randomly, which is not convenient for centralized collection. To solve the above problems, in this embodiment, collection grooves 15 are opened on both the upper and lower sides of the condensation plate 4 and at the top end of the baffle 7.

[0025] In actual use, it is found that the inclined arrangement of the condensation plate 4 and the baffle 7 facilitates the automatic flow and collection of oil. In this embodiment, both the condensation plate 4 and the baffle 7 are inclined towards the semi-circular fixing block 6.

[0026] In actual use, it is found that to facilitate the centralized cleaning of oil, in this embodiment, a centralized box 16 is provided below the bottom end of the hood body 1 where the semi-circular fixing block 6 is located. The centralized box 16 is slidably connected to the hood body 1.

[0027] In actual use, it is found that to strengthen the stability of the semi-circular fixing block 6, in this embodiment, two support blocks 17 are symmetrically fixed to the bottom end of the semi-circular fixing block 6, and the support blocks 17 are fixed to the hood body 1.
