In addition, in other embodiments, the angle between the wind guide blade and the horizontal plane may range from 30 ° to 75 °. It can be understood that, in this rotation range, the wind guiding blades extend obliquely upward, so that the wind blown out from the wind outlet 202 is mainly delivered in an obliquely upward direction, and thus has a large upward wind outlet component, and the upward wind outlet component can push the oil smoke in the upper half of the kitchen space to flow downward, so as to be sucked and purified by the wind inlet 201, and thus the oil smoke in the upper half of the kitchen space can be taken into the air circulation purification (as shown in fig. 5), and the oil smoke in the kitchen can be further reduced.

Furthermore, during the cooking process, a series of chemical reactions such as oxidation, cracking and polymerization occur between the edible oil and the food at high temperature, a large amount of organic fumes are evaporated, and part of decomposed products are emitted into the air in the form of oil mist to form oil fumes. The oil fume includes both edible oil and its heating decomposition or cracking product and also includes the physical and chemical reaction product of protein, polymer compound and various seasoning matters in food, and is one kind of matter containing gas, liquid and solid. Generally, the Particulate Matter Emission (PME) consisting of liquid and solid in the oil smoke emission is defined as PME, and the volatile organic compounds emission (VOCs) is defined as VOCs, and the oil smoke consists of the above two substances.

Therefore, in this embodiment, the air purifying device 2 further includes a filtering element 22 and a purifying air duct, and the air purifying device 2 further includes a purifying fan 23 for driving the air flow in the purifying air duct to flow, so as to adsorb the oil smoke in the kitchen to the air purifying device 2 through the purifying fan 23, specifically, the oil smoke in the kitchen is adsorbed to the air purifying device 2 through the purifying fan 23, the air in the kitchen is controlled to pass through the filtering element 22, so as to adsorb the oil smoke in the air to the filtering element 22, and is conveyed to the purifying air duct for secondary purification, and finally the purified air is conveyed to the kitchen.

Further, the cleaning fan 23 includes a cleaning motor 231 and a cleaning impeller 232, wherein the cleaning motor 231 is an outer rotor motor, and the cleaning impeller 232 is fixedly sleeved outside the outer rotor of the cleaning motor.

Further, the filter member 22 includes a HEPA filter (high efficiency air filter) and an activated carbon filter. The HEPA filter screen is mainly used for filtering particulate matters (liquid and solid) in oil smoke, the materials of the HEPA filter screen can comprise PP filter paper (polypropylene filter paper), glass fibers, PTFE filter paper (polytetrafluoroethylene filter paper), nano fibers, melt-blown polyester non-woven fabrics and the like, the HEPA filter screen has the advantages of being large in dust holding capacity and high in filter precision, the filter efficiency of the oil smoke particulate matters can exceed 90%, and the HEPA filter screen can be processed into required sizes and shapes according to machine type requirements.

Optionally, in the direction of the air flow, the filter element 22 is located upstream of the purge fan 23; so, can make the air current through purification fan 23 be the air current after the purification, avoid the oil smoke to be in purification fan 23 is last to gather, prolongs purification fan 23 life-span.

Further, the air purification device 2 is arranged outside the cigarette machine body 1 so as to be convenient for maintenance and disassembly of internal devices (such as the filter 22, the purification fan 23 and the like). However, the design is not limited thereto, and in other embodiments, the air purification device 2 may also be disposed in the range hood body 1, so as to share the appearance component, and make the appearance of the range hood more concise.

Optionally, the air outlet 202 is disposed on the front surface of the purifying housing 21; thus, after the air purification device 2 is opened, the air purification device 2 blows air forward or at least has a forward air-out component. In the cooking process, a user usually stands in front of the range hood, and the space in front of the range hood can be defined as a user breathing zone. It can be understood that the forward air outlet is favorable for conveying the purified air to the user breathing area, thereby being favorable for improving the air quality of the user breathing area, further reducing the probability of the user sucking the oil smoke, and reducing the harm of the oil smoke to the health of the user. However, the design is not limited thereto, and in other embodiments, the air outlet 202 may also be disposed on the top surface or the side surface of the purifying housing 21.
