Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent;

for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product;

it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1, the embodiment provides a top-suction type range hood, which includes a casing 6, a wind cabinet 4, a smoke collecting hood 5, an oil screen 2 and an oil cup 1, wherein the wind cabinet 4 is installed in the casing 6, an impeller is installed inside the wind cabinet 4, the smoke collecting hood 5 is installed at the bottom of the casing 6, the oil screen 2 is installed at an air inlet of the smoke collecting hood 5, the oil cup 1 is installed at the bottom of the oil screen 2, the wind cabinet 4 is installed in the casing 6 in an inclined manner, and an included angle between a shaft axis of the impeller installed inside the wind cabinet 4 and a horizontal plane at the bottom of the casing 6 is an acute angle of 10 degrees to 80 degrees, so.

As shown in fig. 2, the top-suction type range hood further includes a guide plate 3, the guide plate 3 is obliquely arranged below an air cabinet 4 of the range hood and above a smoke collecting hood 5, the guide plate 3 includes a guide plane 31, a guide curved surface 32 extending towards a fan is arranged at the upper end of the guide plane 31, an oil receiving plane 33 extending towards a casing 6 is arranged at the lower end of the guide plane 31, an oil leaking hole 34 is arranged at the joint of the oil receiving plane 33 and the guide plane 31, and mounting positions 35 are arranged at the left side and the right side of the guide plane 31. In the using process, the flow guide plane 31 of the flow guide plate 3 guides the airflow entering the interior of the casing 6, and the airflow is guided to enter the interior of the air cabinet 4 through the flow guide curved surface 32 of the flow guide plate 3; meanwhile, the oil stain dripped from the bottom plate of the air cabinet 4 is guided and left along the guide plate 3, is discharged from the oil leakage hole 34 and enters the oil cup 1 through the oil screen 2.

The guide plate 3 and the fume collecting hood 5 form an included angle of 10-80 degrees. The specific angle is matched with the air cabinet 4 of the range hood and is used for guiding the flow and the oil.

The number of the oil leakage holes 34 is one or more. The guide plate 3 receives the oil stain flowing down from the air duct, and the oil stain flows down due to the action of gravity because the guide plate 3 is in an inclined state, flows out from the oil leakage hole 34 and enters the oil cup 1 through the oil screen 2.
