AI Technical Summary
While existing range hoods prevent oil dripping, they also reduce suction power and increase fan power and cost.
It adopts an oil-guiding concave single-layer mesh structure, including an air inlet mesh cover, an oil guide pressure plate, a curved oil guide plate, a side oil guide plate and a top oil guide plate. The oil is guided to the top of the oil guide pressure plate to prevent it from dripping out, and the concave air inlet mesh cover increases the air inlet area to form a negative pressure chamber.
Without changing the power of the range hood, the air intake volume is increased, oil dripping is prevented, and costs are reduced.

[0002] Range hoods have become a necessary appliance in modern family kitchens, playing a great role in keeping the kitchen clean. However, existing range hoods generally have the problem of oil dripping. In the prior art, two mesh covers arranged in an interlaced manner are usually provided to prevent oil dripping. However, the two mesh covers arranged in an interlaced manner will reduce the suction power of the range hood, so it is necessary to increase the power of the fan to improve the suction power. This structural arrangement is not worth the loss in preventing oil dripping, and will increase the power and cost of the range hood. Summary of the invention

[0005] Preferably, the top oil guide plate on the front side of the fan is lower at the front and higher at the back, with the front end located above the front end of the oil guide pressure plate, and the top oil guide plate on the rear side of the fan is higher at the front and lower at the back, with the rear end located above the rear end of the oil guide pressure plate.
[0006] Preferably, the air inlet grille and the oil guide pressure plate are arranged with the front portion being higher and the rear portion being lower.
[0007] Preferably, an oil receiving cup is provided at the rear end of the oil guide pressure plate.
[0008] The utility model has the beneficial effects: by respectively arranging a top oil guide plate, a side oil guide plate and an arc-shaped oil guide plate around the fan, the oil adhered to the fan can be guided to the top of the oil guide pressure plate through the oil guide plates at different positions, and the oil will fall on the oil guide pressure plate when dripping, and will not drip from the air inlet mesh cover; the air inlet mesh cover is arranged to be concave with a protrusion in the middle, and the concave air inlet mesh cover can increase the air inlet area and form a negative pressure cavity, thereby increasing the air intake volume without changing the power of the range hood.

[0013] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0014] Embodiment: A high-flow range hood with an oil-concave single-layer mesh structure, such as Figure 1-Figure 3 As shown, it includes a lower shell 1 and an upper shell 2, the upper shell 2 is arranged at the middle position of the upper end of the lower shell 1, and the two are connected to each other, a fan 3 is arranged inside the upper shell 2, the lower shell 1 is a flat structure, an air inlet mesh cover 4 is arranged in the lower shell 1, the air inlet mesh cover 4 is concave and protrudes upward from the middle position, an oil guide pressure plate 5 is arranged at the lower end of the air inlet mesh cover 4, the oil guide pressure plate 5 is pressed on the air inlet mesh cover 4 so that the lower shell 1, the air inlet mesh cover 4 and the oil guide pressure plate 5 are fixedly connected to each other, an arc-shaped oil guide plate 6 is arranged at the bottom of the fan 3, the front end of the arc-shaped oil guide plate 6 is located above the oil guide pressure plate 5, a side oil guide plate 7 is respectively arranged on the left and right sides of the fan 3, and the two side oil guide plates 7 are located above the two sides of the oil guide pressure plate 5, and a top oil guide plate 8 is arranged on the front and rear sides of the upper end of the fan 3.
[0015] The top oil guide plate 8 on the front side of the fan 3 is lower in the front and higher in the back, and its front end is located above the front end of the oil guide pressure plate 5. The top oil guide plate 8 on the rear side of the fan 3 is higher in the front and lower in the back, and its rear end is located above the rear end of the oil guide pressure plate 5; the air inlet mesh cover 4 and the oil guide pressure plate 5 are arranged with a high front and a low back; an oil receiving cup 9 is provided at the rear end of the oil guide pressure plate 5.
[0016] Principle of the utility model: when the range hood is in use, oil will be stuck to the fan 3. When the fan 3 rotates at high speed to generate heat, the oil will be softened by the heat and thus drip. The oil on the left and right sides of the fan 3 will be guided by the side oil guide plates 7 arranged on both sides and directly drip on the left and right sides of the guide pressure plate. The oil on the front side of the fan 3 will drip on the arc-shaped oil guide plate 6, and the oil will be guided to the front end of the oil guide pressure plate 5. The oil on the top of the upper shell 2 is guided to drip on the front and rear ends of the oil guide pressure plate 5 through the setting of two top oil guide plates 8, so as to prevent the oil on the fan 3 and the oil in the upper shell 2 from dripping out from the air inlet mesh cover 4, and the oil guide pressure plate 5 will guide the collected oil into the oil receiving cup 9.
