Road 33.
可选地,集油过滤罩4形成为倒锥形,集油过滤罩4的下表面形成为导油面41,从而有利于集油过滤罩4过滤后的油污沿导油面41向下流向集油件5。如图4所示,集油过滤罩4的倒锥形的下端与集油件5相连,集油过滤罩4的下表面形成为倒锥形面,即导油面41形成为倒锥形面,由此,过滤后的油污沿导油面41流向并汇聚至集油过滤罩4的下端,最后流向集油件5内。Optionally, the oil collecting filter cover 4 is formed into an inverted cone shape, and the lower surface of the oil collecting filter cover 4 is formed as an oil guiding surface 41, thereby facilitating the oil stained by the oil collecting filter cover 4 to flow downward along the oil guiding surface 41. Oil collecting member 5. As shown in FIG. 4, the lower end of the inverted cone of the oil collecting filter cover 4 is connected to the oil collecting member 5, and the lower surface of the oil collecting filter cover 4 is formed as an inverted tapered surface, that is, the oil guiding surface 41 is formed as an inverted tapered surface. Therefore, the filtered oil flows along the oil guiding surface 41 and converges to the lower end of the oil collecting filter 4, and finally flows into the oil collecting member 5.

Therefore, the filtered oil can flow into the oil groove 412 and can flow along the extending direction of the oil guiding groove 412. The oil guiding can be guided downward through the plurality of oil guiding grooves 412 and concentrated to the lower end of the oil collecting filter cover 4, and finally flow direction Oil collecting member 5.
如图4所示,集油件5与集油过滤罩4的下端相连且与集油过滤罩4同轴设置,从而可使得集油过滤罩4、集油烟罩3和集油件5结构更加紧凑和稳定,也有利于过滤后的油污流向集油件5。集油件5形成为开口向上的盘状,从有利于承载油污。结合图1、图3和图4所示,集油件5的中间部分向下凹陷以限定出容纳油污的容纳腔,油污通过开口流向集油件5并可储存在集油件5内,由此可增加集油件5承接油污的承接面积,以保证油污落在集油件5上,从而可进一步地保证锅灶和食物因此干净整洁而不受污染。As shown in FIG. 4, the oil collecting member 5 is connected to the lower end of the oil collecting filter cover 4 and coaxially disposed with the oil collecting filter cover 4, so that the oil collecting filter cover 4, the oil collecting hood 3 and the oil collecting member 5 can be further structured. Compact and stable, it also facilitates the flow of filtered oil to the oil collecting member 5. The oil collecting member 5 is formed in a disk shape with an opening upward, which is advantageous for carrying oil stains. As shown in FIG. 1 , FIG. 3 and FIG. 4 , the intermediate portion of the oil collecting member 5 is recessed downward to define a receiving chamber for containing oil, and the oil flows through the opening to the oil collecting member 5 and can be stored in the oil collecting member 5 by This can increase the receiving area of the oil collecting member 5 to receive the oil stain, so as to ensure that the oil stain falls on the oil collecting member 5, thereby further ensuring that the cooking pot and the food are clean and tidy without being contaminated.
可选地,集油烟罩3的内罩31和外罩32绕其轴线旋转延伸角度可小于360°。即集油烟罩3沿周向方向延伸的角度小于360°。由此,在保证集油烟罩3的集油烟的效果同时可减少集油烟罩3的材料成本,保证集油烟罩3的美观度。优选地,内罩31和外罩32可绕其轴线旋转延伸180°。从而可进一步地保证集油烟罩3的集油烟的效果,并进一步地减少集油烟罩3的材料成本,保证集油烟罩3的美观度。Alternatively, the inner cover 31 and the outer cover 32 of the hood 3 may be rotated by an angle of less than 360° about their axes. That is, the angle of the range hood 3 extending in the circumferential direction is less than 360°. Thereby, the material cost of the oil collecting hood 3 can be reduced while ensuring the effect of the oil collecting smoke of the oil collecting hood 3, and the aesthetics of the oil collecting hood 3 can be ensured. Preferably, inner shroud 31 and outer shroud 32 are rotatable 180° about their axis. Therefore, the effect of the oil collecting smoke of the oil collecting hood 3 can be further ensured, and the material cost of the oil collecting hood 3 can be further reduced, and the aesthetics of the oil collecting hood 3 can be ensured.
可选地,外罩32相对于水平方向倾斜的角度可以为θ,0°≤θ≤90°。换言之,外罩32相对水平方向倾斜设置,且外罩32自上而下朝向外侧倾斜。由此,从而有利于集油烟罩3形成为喇叭形,也有利于从进风口321吸气以形成气流。进一步地,外罩32相对于水平方向倾斜的角度θ可以满足30°≤θ≤60°。Alternatively, the angle at which the outer cover 32 is inclined with respect to the horizontal direction may be θ, 0° ≤ θ ≤ 90°. In other words, the outer cover 32 is inclined with respect to the horizontal direction, and the outer cover 32 is inclined from the top to the bottom. Thereby, it is advantageous to form the hood 3 in a flared shape, and it is also advantageous to draw air from the air inlet 321 to form an air flow. Further, the angle θ at which the outer cover 32 is inclined with respect to the horizontal direction may satisfy 30° ≤ θ ≤ 60°.
可选地,外罩32的下端的截面大致可形成为优弧形,内罩31的下端的截面形成为劣弧形,内罩31的下端设在外罩32的下端内且与外罩32间隔开形成出风口331。如图2所示,外罩32的下端向内弯曲以形成优弧形,即外罩32的下端形成为弧形且弧形的圆弧大于半圆的弧,内罩31的下端向外侧弯曲以形成弧形且弧形的圆弧小于半圆的弧,内罩31的劣弧形的下端位于外罩32的优弧形的下端内。由此,在内罩31的下端和外罩32的下端之间间隔开以形成出风口331,气流从出风口331流出时可沿内罩31的内壁流动,从而可带动内罩31所包围的油烟的流动。Alternatively, the lower end of the outer cover 32 may be formed in a substantially arc shape, and the lower end of the inner cover 31 may be formed in a poor arc shape. The lower end of the inner cover 31 is disposed in the lower end of the outer cover 32 and spaced apart from the outer cover 32. Air outlet 331. As shown in FIG. 2, the lower end of the outer cover 32 is curved inwardly to form a superior arc shape, that is, the lower end of the outer cover 32 is formed in an arc shape and the arc of the arc is larger than the arc of the semicircle, and the lower end of the inner cover 31 is bent outward to form an arc. The curved arc of the shape is smaller than the arc of the semicircle, and the lower end of the inferior arc of the inner cover 31 is located in the lower end of the superior arc of the outer cover 32. Thereby, the lower end of the inner cover 31 and the lower end of the outer cover 32 are spaced apart to form the air outlet 331. When the airflow flows out of the air outlet 331, the airflow can flow along the inner wall of the inner cover 31, so that the oil smoke surrounded by the inner cover 31 can be driven. The flow.
有利地,出风口331的切线方向与水平面之间的夹角可以为φ,0°<φ≤90°。也就是说,出风口331的切线方向相对于水平方向倾斜。气流从出风口331吹出时沿出风口331的切线方向吹出,由此,气流从出风口331吹出时可带动内罩31所包围的油烟的流动,并可带动油烟朝向风道34流动,以增强抽油烟机100的吸烟风劲。 Advantageously, the angle between the tangential direction of the air outlet 331 and the horizontal plane may be φ, 0° < φ ≤ 90°. That is, the tangential direction of the air outlet 331 is inclined with respect to the horizontal direction. When the airflow is blown out from the air outlet 331, the airflow is blown along the tangential direction of the air outlet 331, so that when the airflow is blown out from the air outlet 331, the flow of the soot surrounded by the inner cover 31 can be driven, and the oil smoke can be caused to flow toward the air passage 34 to enhance The smoking range of the range hood 100 is strong.
可选地,辅助风道33的截面积从上向下可逐渐增大。由此,不仅有利于集油烟罩3的喇叭形的结构的形成,而且辅助风道33的下端的截面积大于辅助风道33的上端的截面积,由此,可在辅助风道33的下端形成空气放大,便于辅助风机通过辅助风道33的下端的端部结构进行空气放大效果,以吹出强劲风力,对集油烟罩3的油烟区域形成负压,以有利于油烟的吸取。Alternatively, the cross-sectional area of the auxiliary duct 33 may gradually increase from the top to the bottom. Thereby, not only the formation of the flared structure of the hood hood 3 but also the cross-sectional area of the lower end of the auxiliary duct 33 is larger than the cross-sectional area of the upper end of the auxiliary duct 33, and thus, at the lower end of the auxiliary duct 33 The air is enlarged to facilitate the auxiliary fan to perform air amplification through the end structure of the lower end of the auxiliary air passage 33 to blow strong wind, and a negative pressure is formed on the soot area of the hood 3 to facilitate the suction of the soot.
