TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cooking utensils, and particularly relates to an oil-gas separation device. BACKGROUND

[0002] Oil fume is generated during cooking, and needs to be sent to the outdoor through a discharging channel when cooking in the room. The oil fume contains oil and flue gas, and the oil is easy to block the channel. In the prior art, an oil-gas separation device is arranged in the discharging channel to separate the oil and the flue gas, which is usually installed at the suction port of the oil fume discharging channel to separate most of the oil from the oil fume before discharging.

[0003] The oil-gas separation device in the prior art has various styles such as a mesh, a blade and a grid. The grid-shaped separation device usually includes a plurality of curved separation pieces, and a zigzag oil-gas separation channel is formed between the separation pieces. When the oil-gas mixture passes through the oil-gas separation channel, the oil component contacts and adheres to the separation pieces to be separated from the flue gas. However, the separation pieces in the oil-gas separation device in the prior art are usually fixedly arranged and inconvenient to disassemble and clean. SUMMARY

[0004] To solve the above technical problems, it is necessary to provide an oil-gas separation device which is easy to disassemble and clean.

[0005] To solve the above technical problems, the utility model provides the following technical scheme:

The separation assembly includes a plurality of separation pieces arranged at intervals, and a separation piece connecting piece in the shape of a strip. The plurality of separation pieces are arranged in parallel at equal intervals and connected to the separation piece connecting piece. An oil-gas separation channel is formed between adjacent separation pieces. An oil-gas mixture passage is formed in the separation assembly frame. The oil-gas mixture passage is provided with a separation piece clamping groove corresponding to each separation piece. After all the separation pieces are clamped into the corresponding separation piece clamping grooves, the separation assembly is arranged at the oil-gas mixture passage.

In use, the plurality of separation pieces do not contact each other, the oil fume collides on the plurality of separation pieces, and the oil component contacts and adheres to the separation pieces to be separated from the flue gas. Since the separation pieces correspond to the separation piece clamping grooves one by one, the installation is firm and accurate. Since the separation pieces are clamped with the separation piece clamping grooves, no connecting piece is arranged, and the separation assembly can be conveniently disassembled and assembled.

[0008] Preferably, the oil-gas separation device further comprises a separation device shell, which is used in combination with the separation assembly frame, and the separation piece connector is located between the separation device shell and the separation assembly frame after the combination is completed, and a window is provided in the center of the separation device shell corresponding to the oil-gas mixture opening.

During installation, the separation assembly is installed in the skeleton, and then the cover is closed at the entrance and exit of the skeleton for the separation assembly. This structure facilitates the installation and disassembly of the separation assembly.

[0010] Preferably, two hanging holes are symmetrically provided on the top surface of the skeleton, and the cover comprises two elastic hooks corresponding to the two hanging holes, respectively. When the cover is installed in place, the two elastic hooks are clamped into the corresponding hanging holes to fix the cover on the skeleton.

[0011] Preferably, a limiting convex point is provided on the inner surface of the skeleton, and a clamping hook corresponding to the limiting convex point is provided on the outer surface of the separation assembly frame. The clamping hook cooperates with the limiting convex point, and an external force needs to be applied to make the clamping hook pass over the limiting convex point when the separation assembly frame is installed or removed from the skeleton. This structure prompts the user through the hand feeling whether the separation assembly frame is installed in place, improving the user experience.

[0012] Preferably, the plurality of separation pieces are rotatably connected with the separation piece connector, and each separation piece comprises a rotating shaft clamped into the separation piece clamping groove and capable of rotating therebetween. In this structure, the plurality of separation pieces can rotate and realize linkage through the separation piece connector.

[0013] Preferably, the oil-gas separation channel comprises an inlet section, a first separation section, a centrifugal section, a second separation section, and an outlet section.
