具体实施方式
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9描述根据本发明第一方面实施例的用于油烟机100的集烟罩10。这里，用于油烟机100的集烟罩10也可以用于吸尘器，当集烟罩10用于吸尘器时为吸尘器的集尘罩。
如图1所示，根据本发明第一方面实施例的用于油烟机100的集烟罩10，包括：机壳 11和清洗装置15。
具体地，机壳11内限定了进风腔1102，机壳11上形成有进风口和出风口1101，进风口和出风口1101均与进风腔1102连通，且进风口的导风方向与出风口1101的导风方向呈预定夹角；也就是说，当气流从进风口流入进风腔再从出风口流出时，进风口位置的气流流向和出风口1101位置的气流流向呈一定角度。例如如图1所示，进风口的导风方向(进风口位置的气流的流向)为从下往上的方向，出风口1101的导风方向(出风口位置的气流的流向)为从左往右的方向，此时进风口的导风方向和出风口1101的导风方向呈角度设置，这样，从进风口进入的气流不会直接沿从下往上的方向从出风口1101穿出，而是需要改变流向，这样，可以使得进风气流中夹杂的油烟或灰尘更多地停留在进风腔1102内，由此，可以避免油烟或灰尘从出风口1101进入排气通道中，避免油烟或灰尘在叶轮或驱动电机上积累而影响其正常工作。
有利地，清洗装置15设在机壳11上，且清洗装置15与进风口上下相对，清洗装置15适于向机壳11内喷淋水或洗涤液，以用于清洗机壳11的内壁。当油烟机100需要清洗时，可以通过清洗装置15向机壳11的进风腔1102内喷淋水或洗涤液，用于冲刷清洗进风腔1102周壁上积累的油污或灰尘，由此，可以实现对油烟机100的清洗功能，且结构简单，清洗过程方便快捷，有效地解决了相关技术中的油烟机100的集烟罩10清洗困难的问题。
根据本发明实施例的用于油烟机100的集烟罩10，通过设置清洗装置15，可以实现对集烟罩10的清洗功能，结构简单，清洗过程方便快捷，同时又避免油烟带入电机叶轮通道中。
在本发明的一个实施例中，如图1和图2所示，清洗装置15可以包括：清洗盒151和挡板152，其中，清洗盒151内限定出清洗液容纳腔，清洗盒151的底部形成有喷水孔1501，挡板152设在清洗盒151的底壁上，且挡板152用于打开或关闭喷水孔1501，这里，挡板152可以设在清洗盒151的内侧，也就是说，挡板152设在清洗盒151底壁的上方，挡板152也可以设在清洗盒151的外侧，也就是说，挡板152设在清洗盒151底壁的下方，只要挡板152能实现打开和关闭喷水孔1501的效果即可。当挡板152打开喷水孔1501时，清洗液容纳腔与进风腔1102连通，此时，清洗液容纳腔内的水或洗涤液可以通过喷水孔1501喷淋进入进风腔1102内，以清洗进风腔1102的内壁。
进一步地，如图2所示，清洗盒151可以包括盒体1511和上盖1512，盒体1511的顶部敞开，上盖1512封盖在盒体1511的顶部，由此，可以简化清洗盒151的结构，便于加工制造。优选地，上盖1512上可以设有注入口1502，注入口1502沿上盖1512的厚度方向贯穿上盖1512，且注入口1502与清洗液容纳腔连通，用户可以通过注入口1502向清洗液容纳腔内注入水和洗涤液。这里，用户可以通过手动添加水或洗涤液，也可以自动添加， 例如，清洗装置15可以与控制装置相连，通过控制装置控制油烟机100的清洗功能。
在本发明的一些实施例中，进风口位置可以设有过滤装置12，过滤装置12可以封盖进风口，且过滤装置12与机壳11共同限定了进风腔1102。当油烟机100工作时，外部的油烟先经过过滤装置12初步过滤之后再进入进风腔1102内，由此，可以实现初步分离油烟的效果，减少进入进风腔1102内的油烟或灰尘，从而减少进风腔1102内的油污或灰尘积累。
有利地，过滤装置12可以包括连接段121和延伸段122，连接段121的一端(例如图2中所示的连接段121的下端)与进风口的周沿相连，且连接段121的至少一部分从外周沿到内周沿向上倾斜，也就是说，连接段121的至少一部分在沿进风口的导风方向(例如图2中所示的从下往上的方向)上呈径向尺寸渐缩的锥形，延伸段122与连接段121的另一端(例如图2中所示的连接段121的上端)相连，且连接段121和延伸段122均位于机壳11的内侧，连接段121可以呈沿进风口的导风方向延伸的圆筒状，且连接段121的上端由清洗装置15封闭。由此，可以增大进风口的面积，提高进风口对油烟的吸入效率，减少进风口处油烟的逸散，使得过滤装置12的结构更加简单合理。
优选地，过滤装置12可以具有打开状态和关闭状态，过滤装置12在打开状态时，进风腔1102与外部空间连通，此时，外部的油烟可以通过过滤装置12和进风口进入进风腔1102内，油烟机100为抽油烟状态；当过滤装置12在关闭状态时，过滤装置12可以密封进风口，此时进风腔1102不与外部空间连通，且此时油烟机100可以进入清洗功能，可以向进风腔1102内喷淋水和洗涤液。
在本发明的一些实施例中，用于油烟机100的集烟罩10还可以包括储污盒16，储污盒16可以连接在机壳11的下方，且储污盒16可以与进风口相对。具体地，如图1、图2和图7所示，进风口设置在机壳11的下方，过滤装置12连接在进风口位置并封盖进风口，储污盒16连接在机壳11的下方。当油烟机100正常工作时，储污盒16可以收集沿进风腔1102的内壁向下流动并从进风口流出的油污，当油烟机100启动清洗功能时，当对集烟罩10清洗完成后，可以打开过滤装置12，这样，进风腔1102内的洗涤液以及油污均可以排至储污盒16内，此时，用户可以取下储污盒16，倒掉脏污水，从而可以避免在清洗油烟机100的过程中脏污的洗涤水弄脏灶台或地面。
在本发明的一些实施例中，如图4-图6所示，进风腔1102内可以设有导风件13，导风件13可以沿进风口的导风方向(例如图1中所示的从下往上的方向)延伸，导风件13的外周面上形成有多个导风槽131，多个导风槽131沿导风件13的周向间隔布置，且多个导风槽131沿进风口的导风方向(例如图1中所示的从下往上的方向)延伸。多个导风槽131用于将进风口位置的气流导流至出风口1101位置。进一步地，导风槽131的垂直于导风槽131的延伸方向(例如图1中所示的从下往上的方向)的横截面呈V型，且导风槽131的 相对的两个侧壁圆弧过渡，相邻的两个导风槽131的相邻的两个侧壁之间圆弧过渡。由此，可以增强导风槽131的导风效果，提高油烟机100的抽油烟效率。
在一些实施例中，如图5所示，机壳11的内周壁上可以形成有导风叶片14，导风叶片14可以沿机壳11的内壁向出风口1101方向延伸，且导风叶片14可以呈向机壳11的内周壁凸出的弧形片状，进一步地，导风叶片14可以包括沿机壳11的内周壁间隔布置的多个，且在垂直于进风口导风方向(例如图1中所示的上下方向)的投影平面(例如图5所示的投影平面)上，多个导风叶片14关于出风口1101的中心线对称。由此，可以优化导风叶片14的结构，提高导风叶片14对气流的导流效果。
有利地，导风叶片14可以与机壳11一体成型，例如，导风叶片14可以模铸在机壳11的内周壁上。
在一些实施例中，进风口的导风方向与出风口1101的导风方向之间的夹角可以在45°到135°的范围内。进一步地，进风口的导风方向可以垂直于出风口1101的导风方向。由此，可以进一步减少油烟或灰尘进入驱动电机31或叶轮所在排气通道中，同时，还有利于油烟机100的排气管20的安装或吸尘器出风道的折叠。
根据本发明第二方面实施例的油烟机100，包括：根据本发明上述第一方面实施例的用于油烟机100的集烟罩10、排气管20和驱动装置30，其中，排气管20与出风口1101的周沿相连，排气管20内限定出与进风腔1102连通的排气通道，排气管20的中心轴线与机壳11的中心轴线之间的呈角度设置；驱动装置30设置在机壳11与排气管20之间，驱动装置30用于驱动进风腔1102内的空气从进风口流向出风口1101并由排气通道排出。
根据本发明实施例的油烟机100，通过设置上述第一方面实施例的用于油烟机100的集烟罩10，从而提高了油烟机100的整体性能。
在一些实施例中，驱动装置30可以包括方向可控的变频马达，且当清洗装置15向机壳11内喷淋水或洗涤液时，变频马达反转，此时，变频马达可以驱动叶轮32反转吹入空气，从而起到液体喷淋机壳11内周壁的作用，来实现清洗，同时还可以喷淋机壳11内的其他部件(例如导风件13和导风叶片14)，起到清洗的效果。当变频马达正转时，油烟机100为正常的抽吸风作用。
有利地，机壳11与排气管20之间可以设有过滤件40，驱动装置30可以设在过滤件40的靠近排气管20的一侧(例如图4中所示的过滤件40的左侧)，这样，当进风腔1102内的气流要进入排气管20时，需先经过过滤件40过滤，由此，可以进一步减少进入排气管20内的油污和灰尘，从而进一步避免油烟或灰尘进入驱动装置30中。
优选地，驱动装置30可以包括驱动电机31，且驱动电机31的转速不小于5000rpm。 由此，可以提高油烟机100的吸力，提高吸油烟效率。
下面将参考图1-图9描述根据本发明一个具体实施例的油烟机100。
参照图1，油烟机100包括机壳11、过滤装置12、清洗装置15、排气管20、驱动装置30和储污盒16。

驱动装置30的驱动电机31趋向于大转速范围，优选地，驱动电机31的转速为5000rpm以上，以产生强大的吸力。
过滤装置12位于机壳11的内侧并与机壳11共同限定了进风腔1102，过滤装置12的下端与机壳11的下端相连，且过滤装置12的下部在从过滤装置12的外周沿到内周沿的方向上向上倾斜延伸，过滤装置12的上部呈沿上下方向延伸的圆筒状，过滤装置12的周壁上形成有沿厚度方向贯穿的通气孔1201。过滤装置12还包括用于打开和关闭通气孔1201的隔板，隔板位于通气孔1201的下方，过滤装置12具有打开状态和关闭状态，在打开状态时，进气腔通过通气孔1201与外部空间连通，在关闭状态时，隔板封盖过滤装置12的通气孔1201。
过滤装置12的位于进气腔一侧的周壁上形成有沿上下方向延伸的导油槽1202，导油槽1202从过滤装置12的顶部延伸至过滤装置12的底部，且导油槽1202包括沿过滤装置12的周向均匀间隔布置的多个。
