本申请是基于发明人对以下事实和问题的发现作出的。
叶轮是吸油烟机的核心部件, 叶轮的动平衡精度是影响叶轮性能的关键因素之一。 叶 轮的平衡精度等级越高, 叶轮的许用不平衡量就越小, 叶轮在旋转时由叶轮不平衡引起的 震动就小, 由震动带来的噪声就小、 轴承的寿命延长, 提高了吸油烟机的性能。

下面详细描述本发明的实施例, 所述实施例的示例在附图中示出, 其中自始至终相同 或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。 下面通过参考附图描 述的实施例是示例性的, 旨在用于解释本发明, 而不能理解为对本发明的限制。
下面参考图 1-图 4描述根据本发明实施例的吸油烟机 1。 如图 1-图 4所示, 根据本发 明实施例的吸油烟机 1包括机壳 100、 风机蜗壳组件 200和清洗装置 300。
风机蜗壳组件 200安装在机壳 100上且风机蜗壳组件 200包括具有叶片的叶轮 210。清 洗装置 300安装在机壳 100上, 清洗装置 300具有喷管 310, 喷管 310具有喷孔, 喷管 310 位于叶轮 210的内腔中以清洗处于最低位置处的一部分叶片 (图 1-图 3中的箭头 A所示为 上下方向)。
基于发明人的发现, 吸油烟机 1在使用过程中, 污垢主要积聚在叶轮 210的最下部。 根据本发明实施例的吸油烟机 1通过设置具有喷管 310的清洗装置 300,可以利用喷管 310 清洗叶轮 210上处于最低位置处的一部分叶片。并且,吸油烟机 1还可以通过旋转叶轮 210, 使喷管 310实现对叶轮 210的整个内腔进行清洗。换言之,吸油烟机 1不仅可以对叶轮 210 上污垢最多的部分进行清洗, 而且可以对叶轮 210的整个内腔进行清洗。 由此可以有效改 善叶轮 210的动平衡状态, 提高叶轮 210的动平衡精度, 进而大幅减小叶轮 210旋转时的 震动, 这样既可以减小吸油烟机 1的噪音, 又可以延长吸油烟机 1的使用寿命、 提高吸油 烟机 1的性能。 因此, 根据本发明实施例的吸油烟机 1具有能够实现自动清洗, 噪音小、 使用寿命长、 性能可靠等优点。
其中, 吸油烟机 1的清洗过程可以至少包括两段程序设置。 其中一段为: 叶轮 210不 动, 清洗装置 300启动, 喷管 310仅对叶轮 210上处于最低处的部分叶片进行清洗, 即可 以使喷管 310仅针对聚集的污垢最多的所述叶片进行清洗。 另一段为: 叶轮 210旋转, 清 洗装置 300启动, 喷管 310对叶轮 210的整个内腔进行清洗。
如图 1-图 3所示, 为了便于喷管 310清洗处于最低位置处的一部分叶片, 喷管 310可 以邻近叶轮 210的最低位置设置, 以縮短喷管 310上的喷孔与叶轮 210上最低位置处的叶 片之间的距离。
图 4示出了根据本发明一个具体实施例的吸油烟机 1。如图 4所示,喷管 310上的喷孔 可以包括多组, 所述多组喷孔可以沿喷管 310的轴向间隔布置。 由此可以增大喷管 310对 叶轮 210的轴向的清洗范围。
具体而言, 如图 4所示, 每一组喷孔可以包括中心喷孔 311和分别设在中心喷孔 311 两侧的偏置喷孔 312。 换言之, 每一组喷孔可以包括一个中心喷孔 311和至少两个偏置喷 孔 312, 偏置喷孔 312可以分别设在中心喷孔 311的左右两侧 (图 1和图 3中的箭头 C所 示为左右方向)。通过在喷管 310上设置沿喷管 310的周向间隔开的三个喷孔来构成一组喷 孔, 可以增大每一组喷孔对叶轮 210的周向的清洗范围。
在本发明的一个实施例中, 中心喷孔 311 的开口方向可以朝向正下方, 偏置喷孔 312 的开口方向与中心喷孔 311的开口方向之间的夹角可以在 20-60度之间。 也就是说, 偏置 喷孔 312的中心轴线可以与中心喷孔 311的中心轴线成 20-60度的夹角。 由此可以使中心 喷孔 311正对处于最下方的叶片, 而使偏置喷孔 312分别对准位于最下方叶片两侧的其它 叶片, 进而可以提高每一组喷孔对叶轮 210上污垢最多的叶片的清洗的均匀性。
有利地, 如图 4所示, 每一组喷孔可以为三个, 且所述三个喷孔可以成三角形布置。 具体地说, 每一组喷孔可以包括一个中心喷孔 311和两个偏置喷孔 312, 一个中心喷孔 311 和两个偏置喷孔 312可以分别位于一个三角形的三个顶点处。 更优选地, 所述三角形为等 腰三角形, 中心喷孔 311可以位于所述等腰三角形的顶角处, 而两个偏置喷孔 312可以分 别位于所述等腰三角形的两个底角处。 由此可以保证每一组喷孔的喷洗面积和喷洗压力。
图 1-图 3示出了根据本发明一个具体示例的吸油烟机 1。 如图 1-图 3所示, 风机蜗壳 组件 200还可以包括导流板 220、 蜗壳 230、 冷凝板 250和油网 260。 导流板 220可以安装 在机壳 100内, 导流板 220上可以设有烟口。 蜗壳 230可以安装在导流板 220的后表面上 (图 1-图 3中的箭头 B所示为前后方向), 叶轮 210可以安装在蜗壳 230内。 电机 240可 以安装在蜗壳 230上且电机 240可以与叶轮 210传动连接。冷凝板 250可以设在导流板 220 前面且冷凝板 250可以与导流板 220在前后方向上间隔开。 油网 260可以安装在所述烟口 处。
电机 240运行时驱动叶轮 210旋转, 吸油烟机 1外部的油烟在叶轮 210的作用下从冷 凝板 250与导流板 220之间的缝隙进入导流板 220内, 油烟经过油网 260过滤后进入所述 烟口并排放到室外。 吸油烟机 1 通过设置上述部件组装成风机蜗壳组件 200, 不仅可以实现风机蜗壳组件 200的吸风功能, 而且可以构成近吸式吸油烟机, 由此可以使吸油烟机 1在工作时更加容 易保持清洁。
有利地, 如图 1-图 3所示, 喷管 310可以通过卡夹 221紧固在导流板 220上。 由此可 以利用卡夹 221将喷管 310安装固定在导流板 220上, 以提高喷管 310在导流板 220上的 稳定性, 进而可以提高喷管 310对叶轮 210的清洗效果。
可选地, 如图 1-图 3所示, 导流板 220上可以设有喷管过孔 222, 喷管过孔 222可以 位于所述烟口的正下方, 喷管 310可以穿过喷管过孔 222延伸到叶轮 210的内腔中。 由于 清洗装置 300的其它部件安装在机壳 100内, 在导流板 220上开设喷管过孔 222, 可以便 于喷管 310伸出导流板 220以对叶轮 210进行清洗。
具体而言,喷管 310伸出喷管过孔 222后可以先向上弯折 90度并沿导流板 220的表面延伸 至所述烟口处, 然后喷管 310再次向后折弯 90度以伸进叶轮 210的内腔。其中卡夹 221可以设 置在喷管 310的位于喷管过孔 222和所述烟口之间的部分上。
在本发明的一个具体示例中, 如图 1所示, 为了给喷管 310提供合适的清洗介质以达 到更好的清洗效果, 清洗装置 300还可以包括蒸汽发生器 320、 水源 330和水泵 340。 喷管 310可以与蒸汽发生器 320的出口相连。 水源 330可以与蒸汽发生器 320的进口相连。 水 泵 340可以设在水源 330与蒸汽发生器 320的进口之间。
清洗装置 300工作时, 水泵 340将水源 330中的水泵送到蒸汽发生器 320内, 蒸汽发 生器 320将水加热成热水和 /或高温的水蒸汽, 喷管 310将热水和 /或高温的水蒸汽喷射到 叶轮 210上处于最低位置处的一部分叶片上以实现对叶轮 210的清洗。
