奶瓶清洗机作为一种台上式小型生活类电器，对烘干有更高的要求，由于奶瓶在冲洗的时候必须开口向下，在干燥阶段，由于奶瓶的开口较小，且湿热空气处于上方，如果没有强制换气措施，奶瓶内部的干燥效果极差。
另外，为了减小奶瓶清洗机的投影面积，通常风机等需要安装在底部，并且需要解决防水问题，防止洗涤腔内的水或蒸汽沿风机风道流出。

 有益效果
本发明具有如下有益效果：
本发明的干燥系统通过设置风机、下风道、侧风道、内风道，将风机吸入的空气最终送到洗涤腔内部及奶瓶内，该干燥系统采用内设有风机的下风道、具有竖向延伸段的侧风道以及安装于洗涤腔内的内风道的组合结构，不仅有利于减小奶瓶清洗机的投影面积，且由于侧风道的进气口高于出气口，还能够有效防止或减少洗涤腔内的水或蒸汽沿风道流出。另外，内风道的出口气伸入奶瓶口内，使空气可以进入奶瓶内部，形成强制对流，加强奶瓶内部的干燥效果。
本发明实施例的具体优点有：
1.通过设置空气加热器，可以把风机吸入的低温空气加热为高温空气，被加热后的空气进入奶瓶内部，有利于提高干燥效果。
2.通过下风道上、下片的侧壁上设有至少一个“凵”形的空气加热器支撑筋，使空气加热器和下风道的侧壁保持一定的距离，以免空气加热器表面的高温对下风道的壁有不良影响，另外也有利于空气冷却空气加热器的外表面。
3.通过在侧风道内设置止回阀，尤其是在倒U形结构的高位设置的风门的简便设计，有效避免了洗涤腔内部湿热的空气流到洗涤腔外部。
4. 由于侧风道出气口的面积大于内风道的进气口的面积，形成了从内风道内和侧风道内直接通向所述洗涤腔内的积水回流通道和出风通道，因此就算有水通过内风道的出气口进入内风道，也可以在内风道和侧风道之间的积水回流通道重新回到洗涤腔，不至于积聚在风道内部。侧风道的出气口吹出的空气一部分还经过内风道和侧风道之间的出风通道进入洗涤腔，加强了洗涤腔内的空气对流和干燥效果。

在优选的实施例中，所述下风道内设置有空气加热器2。通过设置空气加热器2，可以把风机1吸入的低温空气加热为高温空气，被加热后的空气进入奶瓶内部，有利于提高干燥效果。
在更优选的实施例中，所述下风道包括下风道上片8和下风道下片3；所述下风道上片8的侧壁上设有至少一个“凵”形的空气加热器支撑筋5，以使空气加热器2与所述下风道上片8的侧壁保持间隔距离，和/或，所述下风道下片3的侧壁上设有至少一个“凵”形的空气加热器支撑筋7，以使空气加热器2与所述下风道下片3的侧壁保持间隔距离。通过下风道上、下片的侧壁上设有至少一个“凵”形的空气加热器支撑筋5、7，使空气加热器2和下风道的侧壁保持一定的距离，以免空气加热器2表面的高温对下风道的壁有不良影响，另外也有利于空气冷却空气加热器2的外表面。
在优选的实施例中，所述下风道在安装所述空气加热器2的位置设有温控器安装孔6，温控器安装于所述温控器安装孔6。
在优选的实施例中，所述侧风道整体上呈倒U形结构。
在更优选的实施例中，所述侧风道包括第一侧风道组件（可包括第一侧风道组件右片10和第一侧风道组件左片14）和第二侧风道组件17，所述第一侧风道组件呈倒J形结构，所述第二侧风道组件17呈L形结构，所述第一侧风道组件下端的进气口与所述下风道的出气口相通，所述第一侧风道组件上端的出气口与所述第二侧风道组件17上端的进气口相通，所述第二侧风道组件17下端的出气口与所述内风道18的进气口相通。
在更优选的实施例中，所述侧风道内设置有止回阀。
在进一步优选的实施例中，所述止回阀包括在所述倒U形结构的高位设置的整体呈片状的风门16，所述风门16具有风门安装孔15，所述侧风道的两个内侧壁上对应地设置有的风门安装柱12，所述风门16通过其风门安装孔15安装在所述两个内侧壁的风门安装柱12上。此外，也可以是所述风门16具有风门安装柱，所述侧风道的两个内侧壁上对应地设置有的风门安装孔，所述风门16通过其风门安装柱安装在所述两个内侧壁的风门安装孔上。
通过在侧风道内设置止回阀，尤其是在倒U形结构高位处设置风门16的简便设计，有效避免了洗涤腔内部湿热的空气流到洗涤腔外部。
在优选的实施例中，所述侧风道出气口的面积大于所述内风道18的进气口的面积，形成从所述内风道18内和所述侧风道内直接通向所述洗涤腔内的积水回流通道和出风通道。由于侧风道出气口的面积大于内风道18的进气口的面积，形成了从内风道18内和侧风道内直接通向所述洗涤腔内的积水回流通道和出风通道，因此就算有水通过内风道18的出气口进入内风道18，也可以在内风道18和侧风道之间的积水回流通道重新回到洗涤腔，不至于积聚在风道内部。侧风道的出气口吹出的空气一部分还经过内风道18和侧风道之间的出风通道进入洗涤腔，加强了洗涤腔内的空气对流和干燥效果。
在优选的实施例中，所述内风道18包括进气管道19、环形通气座以及至少一个柱状出气管，所述内风道18的进气口与所述进气管道19的进气口相通，所述进气管道19的出气口与所述环形通气座相通，所述至少一个柱状出气管竖直向上布置在所述环形通气座上，并与所述环形通气座相通。更优选地，多个柱状出气管均匀间隔布置在环形通气座上。
在更优选的实施例中，所述进气管道19为由两个弧形分支组成的环形进气管道19，环形进气管道19的一端设置进气口，进气口通过两个弧形分支分别与环形通气座相通。
在另一种实施例中，一种奶瓶清洗机，具有前述任一实施例所述的干燥系统。
以下参照各个附图描述本发明典型实施例的具体特征。
风机1（见图1），具有进气口A1，用于吸取外部的低压空气，设有出气口B1，把经风机叶轮加压的空气从出气口B1排出。
空气加热器2（见图2），风机排出的空气，经过空气加热器后温度升高。
下风道下片3（见图3），是半包围壳体，设有进气口A2，与离心式风机的进气口A1相通。在下风道下片3侧壁上设有至少一个“凵”形的空气加热器支撑筋5，空气加热器安装在“凵”形的凹槽内（见图4）。设有温控器安装孔，用于安装温控器，限制空气加热器的温度，当空气加热器超过设定温蒂，温控器断开空气加热器的供电。下风道下片3的外壁设有若干凸起4。
下风道上片8（见图5），是半包围壳体，在下风道上片8侧壁上设有至少一个“凵”形的空气加热器支撑筋7，空气加热器安装在“凵”形的凹槽内，使空气加热器和下风道上片8的侧壁保持一定的距离，以免空气加热器表面的高温对下风道上片8有不良影响，另外也有利于空气冷却空气加热器的外表面。下风道上片8的外壁设有若干卡扣9，和下风道下片3的凸起4相互扣合，可以把离心式风机和空气加热片固定于两者形成的壳体中。另外当两者扣合（见图6），形成了下风道出气口B2。
第一侧风道组件右片10（见图7），整体呈倒“U”形壳体，在外侧壁上设有卡扣11。
第一侧风道组件左片14（见图8），整体呈倒“U”形壳体，在外侧壁上设有凸起13，在倒“U”形的高位，设有风门安装柱12。
风门16（图9），整体呈片状，在一端设有风门安装孔，风门安装孔15套入风门安装柱12，可以灵活摆动，但只能被进气口A3进入的空气吹起来，起到单向流通空气的作用。
第一侧风道组件（见图10），由第一侧风道组件左片14、第一侧风道组件右片10的卡扣11和凸起13相互扣合，形成了进气口A3和出气口B3。
第二侧风道组件17（见图11、图12），整体呈L形壳体，在一端设有进气口A4，另外一端设有出气口B4，且进气口A4高出出气口B4高度。进气口A4处于洗涤腔外部，出气口B4处于洗涤腔内部。
内风道18（见图13），具有进气口A5，至少一个出气口B5，进气口A5和出气口B5之间通过进气管道19连通。内风道18安装于洗涤腔内部，出气口B5伸入奶瓶口。
侧风道的出气口B4和内风道18的进气口A5对接（图14），侧风道的出气口B4的面积大于内风道18的进气口A5的面积，出气口B4的空气一部分进入进气口A5，另外一部分直接进入洗涤腔。
以上装配后如图15和图16所示，下风道出气口B2与侧风道组件的进气口A3相连通，侧风道组件的出气口B3与进气口A4相连通，出气口B4与进气口A5相连通。
以上内容是结合具体/优选的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，其还可以对这些已描述的实施方式做出若干替代或变型，而这些替代或变型方式都应当视为属于本发明的保护范围。
