Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to an oil fume separator and a range hood. Background Technology

[0002] A typical oil fume separator includes an outer oil filter plate and an inner oil filter plate, both of which are equipped with vertically staggered smoke baffles to form an S-shaped oil fume duct. The vertically spaced smoke baffles form multiple vertical rows of inlet and outlet air channels, such as the oil fume separator and range hood disclosed in patent number CN202220504803.0.

[0003] However, this type of oil fume separator usually adopts a flat plate structure, with the smoke baffle and oil fume trough being uniform vertical strip structures, resulting in a limited air intake area. The flue gas cannot be effectively guided and diffused to more working areas of the oil fume separator, and instead concentrates in a localized area near the burner for oil fume adsorption, making it difficult to further improve the oil fume separation rate.

[0004] Therefore, further improvements are needed. Utility Model Content

The outer oil filter plate is provided with several spaced outer smoke baffles; the inner oil filter plate is provided with several spaced inner smoke baffles; the outer smoke baffles are located between two adjacent inner smoke baffles; two adjacent outer smoke baffles form a flue inlet; two adjacent inner smoke baffles form a flue outlet; the outer smoke baffles and the inner smoke baffles form an oil fume channel, which is connected to the flue inlet and the flue outlet respectively; The flue inlet is divided into a main flue inlet and a secondary flue inlet; the width of the main flue inlet is greater than the width of the secondary flue inlet; the secondary flue inlet is located to the side of the main flue inlet; a protruding partition rib is provided on the side of the secondary flue inlet away from the main flue inlet; the protruding partition rib extends longitudinally along the outer smoke baffle and protrudes outward from the outer smoke baffle.

[0011] Optionally, an oil outlet groove is formed between the lower side of the outer frame and the inner oil filter plate.

[0022] Example Reference Figures 1 to 3 The present invention proposes an oil fume separator, comprising: an outer oil filter plate 10, an inner oil filter plate 20, and a frame 30; The frame 30 is recessed inward to form a smoke chamber 40, and the inner oil filter plate 20 is disposed on the inner concave end face of the smoke chamber 40; the outer oil filter plate 10 is detachably installed on the frame 30. The outer oil filter plate 10 is provided with a plurality of spaced outer smoke baffles 11; the inner oil filter plate 20 is provided with a plurality of spaced inner smoke baffles 21; the outer smoke baffles 11 are located between two adjacent inner smoke baffles 21; two adjacent outer smoke baffles 11 form a flue inlet 50 at intervals; two adjacent inner smoke baffles 21 form a flue outlet 70 at intervals; the outer smoke baffles 11 and the inner smoke baffles 21 form an oil fume channel 60 at intervals, which is connected to the flue inlet 50 and the flue outlet 70 respectively; The flue inlet 50 is provided with a main flue opening 51 and a secondary flue opening 52; the width of the main flue opening 51 is greater than the width of the secondary flue opening 52; the secondary flue opening 52 is located to the side of the main flue opening 51; a protruding partition rib 12 is provided on the side of the secondary flue opening 52 away from the main flue opening 51; the protruding partition rib 12 extends longitudinally along the outer smoke baffle 11 and protrudes outward toward the outer side of the outer smoke baffle 11.

[0023] In this invention, the smoke-collecting chamber 40 formed by the inward indentation of the frame 30 effectively gathers the smoke and prevents it from escaping; the smoke-blocking strips on the outer oil filter plate 10 and the inner oil filter plate 20 are staggered to form a meandering S-shaped oil fume channel 60, which increases the contact area and residence time between the oil fume and the filter plate, thereby improving the separation rate; the flue inlet 50 is provided with a main flue inlet 51 and a secondary flue inlet 52. The main flue inlet 51 is wider, which facilitates concentrated air intake, while the secondary flue inlet 52, in conjunction with the outwardly protruding partition rib 12, guides the smoke to diffuse to a wider area, avoids local overload, and achieves uniform adsorption; the outer oil filter plate 10 is designed to be detachable, which facilitates cleaning and maintenance.

[0024] In this embodiment, a main flue outlet 51 and two auxiliary flue outlets 52 on both sides form a set of longitudinally extending fume adsorption zones; adjacent fume adsorption zones are separated by protruding partition ribs 12. By combining the main flue outlet 51 and the two auxiliary flue outlets 52 into longitudinally extending fume adsorption zones and separating adjacent areas by protruding partition ribs 12, independent operation of multiple zones is achieved, mutual interference of airflow is avoided, and each adsorption zone can effectively treat fumes, thereby improving the overall separation rate and the working stability of the equipment.

[0025] In this embodiment, the secondary flue opening 52 is vertically divided into several segments. This vertical division of the secondary flue opening 52 breaks the uniform vertical structure, increases airflow turbulence and the contact frequency between oil fumes and the oil filter plate, while also refining the airflow channel, reducing wind resistance, improving air intake efficiency and the uniformity of oil fume separation; it also improves the structural strength of the outer smoke baffle 11.

[0026] In this embodiment, the frame 30 includes an outer frame 31 and two side plates 32; the two side plates 32 are disposed on both sides of the outer frame 31 and connected to the outer frame 31 and the inner oil filter plate 20. The frame 30 is composed of an outer frame 31 and two side plates 32, which has a simple and reliable structure, facilitates the installation and fixing of the oil filter plate, provides sufficient support strength, ensures the stability and sealing of the equipment during operation, and reduces vibration and noise.

[0027] In this embodiment, the outer frame 31, side plate 32, and inner oil filter plate 20 are integrally formed. This integral forming eliminates connection gaps, improves structural integrity and sealing, reduces the possibility of air leakage, and simplifies the manufacturing process.

[0028] Specifically, an oil outlet groove 33 is formed between the lower side of the outer frame 31 and the inner oil filter plate 20, which can effectively collect the separated oil and discharge it in a centralized manner to prevent oil accumulation or leakage.

[0029] In this embodiment, a handle groove 13 is provided above the outer oil filter plate 10, which allows the user to easily disassemble and install the outer oil filter plate 10.

[0030] This utility model also provides another technical solution: a range hood, including the above-mentioned oil fume separator.
