本发明上述的和/或附加的方面和优点从下面结合附图对实施例的描述中将变得明显和容易理解，其中：
图1是根据本发明实施例的洗碗机的结构示意图；
图2是根据本发明实施例的洗碗机的局部结构示意图。
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。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。
下面参考附图描述根据本发明实施例的洗碗机10。如图1和图2所示，根据本发明实施例的洗碗机10包括机体101、风道102、具有纳米二氧化钛的触媒件103和用于向触媒件103发射紫外光的紫外灯104。
机体101内具有用于容纳餐具的容纳腔1011，容纳腔1011的壁上设有气体进口1012和气体出口1013。风道102的出气口与气体进口1012连通，风道102的进气口与气体出口1013连通。触媒件103设在风道102内，紫外灯104设在风道102内。
当洗碗机10发出难闻气味后或者洗碗机10使用一段时间后，用户可以打开紫外灯104，紫外灯104向触媒件103发射紫外光以便进行光催化，从而可以产生具有高电活性的氢氧自由基(OH自由基)和过氧离子。氢氧自由基和过氧离子可以通过风道102进入到容纳腔1011内。氢氧自由基和过氧离子可以与容纳腔1011内的空气中的污染物(例如细菌、真菌、挥发性有机化合物、任何其他可以产生难闻气味的物质)结合，结合后会产生化学反应以便有效地氧化这些污染物，从而将这些污染物分解(破坏)为无害的二氧化碳和水分子，从而消除洗碗机10的难闻气味，使得容纳腔1011内的空气更加洁净、更加无味。
根据本发明实施例的洗碗机10通过在风道102内设置紫外灯104和具有纳米二氧化钛的触媒件103，从而可以通过紫外线照射触媒件103来产生氢氧自由基和过氧离子，由此可以利用氢氧自由基和过氧离子来氧化容纳腔1011内的细菌、真菌、挥发性有机化合物等 污染物，并产生无害的二氧化碳和水分子。由此可以使洗碗机10的容纳腔1011内的空气更加洁净、更加无味，使得洗碗机10更加清洁卫生。
而且，光催化氧化还具有低成本、容易实现、无毒、化学机械稳定和利用率高等优点。此外，与直接光分解技术不同，光催化氧化可以避免产生中间产物。
因此，根据本发明实施例的洗碗机10具有清洁卫生、无味等优点。
如图1和图2所示，根据本发明的一些实施例的洗碗机10包括机体101、风道102、具有纳米二氧化钛的触媒件103和用于向触媒件103发射紫外光的紫外灯104。
机体101内具有用于容纳餐具的容纳腔1011，容纳腔1011的壁上设有气体进口1012和气体出口1013。有利地，如图1所示，气体进口1012设在容纳腔1011的周壁上，且气体进口1012邻近容纳腔1011的底壁，气体出口1013设在容纳腔1011的周壁上，且气体出口1013邻近容纳腔1011的顶壁。
氢氧自由基和过氧离子从邻近容纳腔1011的底壁的气体进口1012进入到容纳腔1011内，并向上流动，以便氧化整个容纳腔1011内的污染物，避免出现死角。由此可以使洗碗机10的结构更加合理。
在本发明的一个实施例中，洗碗机10进一步包括风扇105，风扇105设在风道102内。通过设置风扇105，可以加快氢氧自由基和过氧离子在容纳腔1011内的流动速度，从而可以加快消除洗碗机10的难闻气味的速度。
有利地，风扇105可以是多个，由此可以进一步加快氢氧自由基和过氧离子在容纳腔1011内的流动速度，从而可以进一步加快消除洗碗机10的难闻气味的速度。
如图1所示，在本发明的一些示例中，洗碗机10进一步包括风扇105，风道102包括第一子风道1021和第二子风道1022。其中，第一子风道1021的进气口10211与气体出口1013连通，第一子风道1021的出气口10212与风扇105的进气口连通，第二子风道1022的进气口10221与风扇105的出气口连通，第二子风道1022的出气口10222与气体进口1012连通。由此不仅可以更加方便地、容易地安装风扇105，而且可以使洗碗机10的结构更加合理。
触媒件103可以包括基板和涂覆在该基板上的纳米二氧化钛涂层。也就是说，纳米二氧化钛可以作为薄膜支撑在适当的基板上，纳米二氧化钛可以容易地与处理后的水分离。
如图2所示，在本发明的一个示例中，触媒件103可以是多个，多个触媒件103沿紫外灯104的长度方向间隔开地设置，每个触媒件103的长度方向垂直于紫外灯104的长度方向。由此可以更好地进行光催化反应，从而可以产生更多的氢氧自由基和过氧离子，以便更加有效地净化容纳腔1011内的空气、消除容纳腔1011内的难闻气味。
有利地，触媒件103和紫外灯104设在第二子风道1022内。由此可以使洗碗机10的 结构更加合理。
在本发明的一个具体示例中，如图2所示，第二子风道1022包括第一连接段10223、第二连接段10224、扩径段10225、容纳段10226和缩径段10227。第一连接段10223的一端与风扇105的出气口相连，第二连接段10224的一端与气体进口1012相连。
扩径段10225的一端与第一连接段10223的另一端相连。容纳段10226的一端与扩径段10225的另一端相连，触媒件103和紫外灯104设在容纳段10226内。缩径段10227的一端与容纳段10226的另一端相连，缩径段10227的另一端与第二连接段10224的另一端相连。
其中，容纳段10226的直径等于扩径段10225的最大直径以及缩径段10227的最大直径。换言之，扩径段10225内限定的空间和缩径段10227内限定的空间都可以是圆台状，且扩径段10225内限定的空间的直径沿气体流动方向增大，缩径段10227内限定的空间的直径沿气体流动方向减小。容纳段10226内限定的空间为圆柱状。由此可以更加方便地、容易地安装触媒件103和紫外灯104，从而可以使洗碗机10的结构更加合理。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接或彼此可通讯；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、 “下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
