An auxiliary air passage 33 is defined between the inner cover 31 and the outer cover 32. The auxiliary fan is disposed in the auxiliary air passage 33, and the outer cover 32 is disposed. An air inlet 321 is provided, and the air inlet 321 is in communication with the auxiliary air duct 33. The bottom of the inner cover 31 and the bottom of the outer cover 32 are spaced apart to form an air outlet 331. The air outlets 331 are respectively connected to the auxiliary air duct 33 and the air duct 34. . Thus, the auxiliary air blower can generate an auxiliary air flow. Specifically, the auxiliary air flow flows from the air inlet 321 on the outer cover 32 to the auxiliary air passage 33, and is guided to the air outlet 331 through the auxiliary air passage 33, and finally blows out from the air outlet 331 to assist When the airflow is blown out from the air outlet 331, the flow of air flowing to the hood 3 can be driven to form a negative pressure in the space surrounded by the inner cover 31 of the hood 3, thereby promoting the hood. 3 The flow of the soot during work to achieve the purpose of strong suction of the range hood 100 to improve the smoke absorption effect of the range hood 100.
根据本发明实施例的抽油烟机100,集油烟罩3包括间隔开布置的内罩31和外罩32,内罩31和外罩32之间限定出辅助风道33,外罩32上设有与辅助风道33导通的进风口321,内罩31和外罩32的底部间隔开设有与风道34导通的出风口331,辅助风机设在辅助风道33内。辅助风机工作以产生气流,气流通过出风口331吹出,从而可带动流向集油烟罩3所包围的空气流的流动,以在集油烟罩3的内罩31所包围的空间内形成负压,进而可促进集油烟罩3工作时的油烟的流动,以达到抽油烟机100对油烟强劲吸取的目的,提高抽油烟机100的吸油烟效果。According to the range hood 100 of the embodiment of the present invention, the hood 3 includes an inner cover 31 and a cover 32 which are spaced apart from each other, and an auxiliary air passage 33 is defined between the inner cover 31 and the outer cover 32, and the auxiliary cover 32 is provided with an auxiliary wind The air inlet 321 of the duct 33 is connected to the bottom of the inner cover 31 and the outer cover 32, and an air outlet 331 which is electrically connected to the air duct 34 is disposed. The auxiliary fan is disposed in the auxiliary air duct 33. The auxiliary fan operates to generate an air flow, and the air flow is blown out through the air outlet 331 to drive the flow of the air flow surrounded by the hood 3 to form a negative pressure in the space surrounded by the inner cover 31 of the hood 3, thereby The flow of the soot during the operation of the oil hood 3 can be promoted to achieve the purpose of the strong suction of the range hood 100, and the effect of the range hood of the range hood 100 is improved.
在本发明的一些实施例中,集油烟罩3可形成为开口向下的喇叭形。换言之,集油烟罩3的开口在由下至上的方向上呈收缩趋势,集油烟罩3的下端开口朝向炉灶,在风机系统2的作用下,炉灶产生的油烟可流向集油烟罩3的开口,并沿集油烟罩3的风道34流动,通过喇叭形的集油烟罩3从而可更好地吸收和收集烟气。结合图1和图4所示,集油烟罩3的内罩31和外罩32均可形成为喇叭形,外罩32设在内罩31的外侧且与内罩31之间限定出辅助风道33。In some embodiments of the invention, the hood 3 may be formed as a flared opening. In other words, the opening of the hood 3 shrinks in a downward-to-up direction, and the lower end opening of the hood 3 faces the stove. Under the action of the fan system 2, the soot generated by the stove can flow to the opening of the hood 3. And flowing along the air passage 34 of the oil collecting hood 3, through the flared oil collecting hood 3, the flue gas can be better absorbed and collected. 1 and 4, the inner cover 31 and the outer cover 32 of the hood 3 may be formed in a flared shape, and the outer cover 32 is disposed outside the inner cover 31 and defines an auxiliary air passage 33 between the inner cover 31 and the inner cover 31.
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°。如图5所示,集油烟罩3的沿周向方向延伸的角度为α,α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°,即α=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°. As shown in Fig. 5, the angle of the range hood 3 extending in the circumferential direction is α, and α 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, the inner shroud 31 and the outer shroud 32 are rotatable about their axis by 180°, i.e., a = 180°. 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。优选地,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. Preferably, 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和图3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的下端之间间隔开且配合以形成出风口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 superior 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 to form a lower end. Tuyere 331. As shown in FIGS. 2 and 3, 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 arcuate arc is larger than the semicircular arc; the lower end of the inner cover 31 is bent outward. In order to form an arc having an arc shape and an arc shape smaller than a semicircle, 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 and cooperate 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, thereby enclosing the inner cover 31. The flow of soot.
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的切线方向流出,由此,气流从出风口331流出时可带动内罩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。优选地,30°≤φ≤60°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 flows out in the tangential direction of the air outlet 331. Therefore, when the airflow flows out of the air outlet 331, the flow of the oil smoke 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. Preferably, 30° ≤ φ ≤ 60°
