本发明的最佳实施方式
[0022] 为了对本发明的技术特征、 目的和效果有更加清楚的理解, 现对照附图详细说 明本发明的具体实施方式。
[0023] 如图 1、 2所示, 本发明一实施例的旋风式抽油烟机, 包括机壳 10、 连接在机壳 10上的出烟管道 20、 以及至少两组相对设置在出烟管道 20侧壁上的风力组件 30 。 机壳 10背向出烟管道 20的一侧形成有内凹的集烟区域 100, 且机壳 10上设有连 通出烟管道 20和集烟区域 100的通口 101, 风力组件 30驱动空气以在出烟管道 20 内形成旋风 (如图 2中箭头所示) , 使得在集烟区域 100形成负压, 从而在集烟 区域 100产生由下至上的吸力, 将油烟从集烟区域 100吸进出烟管道 20, 以排出 外部。
[0024] 其中, 如图 1、 4、 5所示, 风力组件 30包括风机 31、 风机壳 32以及导风管道 33 , 风机 31安装在风机壳 32内, 风机壳 32对应风机 31的进风方向和出风方向分别 设有进风口 321和出风口 (未图示) , 导风管道 33连接在风机壳 32的出风口上。 在出烟管道 20上, 导风管道 33沿着出烟管道 20的侧壁向出烟管道 20内延伸, 从 而导风管道 33的自由端的出口位于出烟管道 20内。 风力组件 30设有至少两组, 因此在出烟管道 20侧壁上有至少两个相对的风机 31 ; 风机 31工作吋, 将空气从 进风口 321抽入, 然后从出风口沿着导风管道 33输出到出烟管道 20中, 相对两个 风机 31输出的空气沿着出烟管道 20的内壁面形成旋风, 该旋风上下两侧形成空 气压力差, 而其中一侧集烟区域 100形成负压, 从而在集烟区域 100产生由下至 上的吸力, 将油烟吸进出烟管道 20, 油烟顺着出烟管道 20往上走以排出外部。
[0025] 至少两组风力组件 30在出烟管道 20上位于同一水平面, 且至少两组风力组件 30 的导风管道 33在出烟管道 20上沿出烟管道 20的周向向同一侧延伸, 即都是顺吋 针方向或逆吋针方向, 利于其驱动的空气在出烟管道 20内对流形成旋风。 风力 组件 30的数量可根据出烟管道 20的尺寸、 抽油烟强度进行设置。 优选地, 风机 3 1的进风方向与出烟管道 20相垂直。 出烟管道 20为圆筒状金属管道。 圆筒状的设 置, 利于空气受风力组件 30的驱动形成旋风; 出烟管道 20采用金属材料制成, 在耐高温的同吋还可使油烟中的油雾在其内壁面上冷凝成油滴, 在重力作用下 往下流。 由于风力组件 30远离集烟区域 100设置在出烟管道 20的侧壁上, 油烟在 排出过程中不需经过风力组件 30, 因此避免其中的油雾附着到风机 31上, 利于 清洗。 此外, 在烹饪过程中和油烟中的热量没有直接接触风机 31, 降低风机 31 的温升, 从而提高风机 31的使用寿命。
[0026] 风力组件 30可通过紧固件固定连接在出烟管道 20侧壁的外壁面上, 或者嵌设到 出烟管道 20的侧壁上, 或者贴合在出烟管道 20侧壁的内壁面上, 易于拆装、 维 护。 参考图 1, 在本实施例中, 风机壳 32固定连接在出烟管道 20侧壁的外壁面上 ; 出烟管道 20的侧壁还设有贯通该侧壁的安装孔 21, 导风管道 33紧密嵌设在安 装孔 21中; 该导风管道 33的自由端则伸到出烟管道 20的内侧。 导风管道 33紧密 嵌设在安装孔 21中, 避免其和安装孔 21之间存在缝隙, 影响旋风形成。 为提升 外在美观性, 导风管道 33呈弧形, 从而可沿着出烟管道 20的侧壁形状设置在其 上。 在其他实施例中, 风机壳 32可固定连接并贴合在出烟管道 20侧壁的内壁面 上, 此吋出烟管道 20侧壁设有与风机壳 33的进风口 321相对连通的风口, 通过风 机 31的抽吸, 空气依次从风口和进风口进入风机 31中。

[0028] 在其他实施例中, 出烟管道 20的一端也可不延伸至下盖 12, 而在夹层空间 102 内设置导引隔板; 导引隔板于通口 101的外周连接在上盖 11和下盖 12之间, 将通 口 101和夹层空间 102相隔幵。 当通口 101贯通上盖 11的一端内径大于其贯通下盖 12的一端内径, 导引隔板可锥形设置, 内径较大的一端连接上盖 11, 内径较小 一端连接下盖 12, 可更好地将油雾引流下来。
[0029] 下盖 12呈弯折状, 从而其远离上盖 11的一侧形成有集烟区域 100。 位于通口 101 周围的下盖 12的侧面可为斜面, 有利于油烟的进入和回流油烟的导流承接。 上 盖 11可对应下盖 12形状设置, 且包覆在下盖 12外周。 优选地, 该上盖 11由金属 材料制成, 其可与出烟管道 20通过焊接固定连接在一起。 出烟管道 20也可通过 螺丝等紧固件与上盖 11和下盖 12紧固连接, 并且在出烟管道 20与上盖 11和下盖 1 2的连接出还可设置密封圈, 加强其之间的密封性, 防止油烟从出烟管道 20与上 盖 11之间、 以及出烟管道 20与下盖 12之间的缝隙流出。
[0030] 进一步地, 如图 1-3所示, 该抽油烟机还包括正对通口 101连接在通口 101下方 的接油盘 40, 在出烟管道 20内壁面上冷凝成的油滴, 在重力作用下依次沿着内 壁面和通口 101流到该接油盘 40中。 该抽油烟机还包括支架 50, 接油盘 40连接在 支架 50—端, 支架 50的另一端于通口 101的外周连接在机壳 10上; 部分油滴可通 过通口 101后直接落入接油盘 40中, 部分油滴还可沿着支架 50流入到接油盘 40中 。 该支架 50可采用可拆卸方式连接在机壳 10上, 方便清洗吋拆下。
[0031] 支架 50可优选为金属支架。 在本实施例中, 支架 50由数个金属杆相间隔焊接形 成。 数个金属杆相间隔围绕形成网状的支架 50, 其一端位于通口 101的外周连接 在机壳 10上, 在不影响油烟通过的同吋, 将油雾引导流入接油盘 40中。
[0032] 另外, 如图 1所示, 该抽油烟机还包括设置在机壳 10中的控制单元 (未图示) 、 以及设置在机壳 10上的控制面板 60; 控制面板 60和风力组件 30均与控制单元 电连接。 控制单元包括电路板, 其可远离通口 101设置在上盖 11和下盖 12之间的 夹层空间 102中。 控制面板 60可设置在上盖 11的外表面上, 可为触控面板或按钮 控制面板, 用于操作该抽油烟机的相应功能。
[0033] 上述的用于金属材料制成的部件, 如出烟管道 20和机壳 10等, 为了防止所述部 件生锈及加强美观性, 还对该些部件的表面进行处理。
[0034] 以上所述仅为本发明的实施例, 并非因此限制本发明的专利范围, 凡是利用本 发明说明书及附图内容所作的等效结构或等效流程变换, 或直接或间接运用在 其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
