图4是本发明实施例的储藏装置中紫外消毒部件的结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图和具体实施例 对本发明作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
应该理解，尽管在这里会用术语第一、第二、第三等来描述不同的元件、组件、区域、层和/或部分，但是这些元件、组件、区域、层和/或部分不应受这些术语限制。这些术语仅用来将一个元件、组件、区域、层或部分与另一区域、层或部分区别开来。因此，在不脱离本发明的教导的情况下，下面讨论的第一元件、组件、区域、层或部分可被称为第二元件、组件、区域、层或部分。
为了便于描述，在这里可使用空间相对术语，如“下”、“上”等来描述如在图中所示的一个元件或特征与其它元件或特征的关系。应该理解的是，空间相对术语意在包含除了在附图中描述的方位之外的装置在使用或操作中的不同方位。例如，如果附图中的装置被翻转，则描述为相对于其它元件或特征处于“下方”的元件随后将被定位为相对于其它元件或特征处于“上方”。因而，示例性术语“在…下方”可包括“在…上方”和“在…下方”两种方位。所述装置可被另外定位(旋转90度或者在其它方位)，并对在这里使用的空间相对描述语做出相应的解释。
本发明实施例提供了一种储藏装置，请参阅图1、图2和图3所示，该储藏装置包括：储藏装置本体10、紫外消毒部件20和冷却部件30。其中，储藏装置本体10具有储藏空间101，还开设有与外界连通的门体102；紫外消毒部件20用于对储藏空间101进行紫外线照射，冷却部件30设于储藏装置本体10的底部，与待储藏物品200直接接触，增加冷却效果。紫外消毒部件20包括一紫外光源组件201和一具有封闭空腔202a的光漫射组件202，紫外光源组件201的紫外光射出时经过封闭空腔202a的上表面、进入封闭空腔202a、再从封闭空腔202a的下表面射出。紫外消毒部件20优选设于门体102内侧，在开门和关门时空气进入后，在最短的射程内对进入空气进行消毒，降低紫外线的传播损耗，增加消毒效果。
请参阅图2和图3所示，光漫射组件202包括沿着紫外光的射出方向依次平行间隔设置的第一板体2021和第二板体2022，第一板体2021和第二板体2022分别用于形成所述封闭空腔202a的上表面和下表面，第一板体2021、第二板体2022以及侧板2023围成了封闭空腔202a，第一板体2021入光面设有第一漫射结构203，第一板体2021出光面设有第二漫射结构204，第二板体2022的入光面设有第三漫射结构205。
请参阅图2所示，紫外光源组件201包括光源板2011和紫外光LED 2012，光源板2011上设有多个用于安装紫外光LED 2012的安装座2013。在一个优选实施方式中，光源 板2011由金属铝制成，朝向第一板体2021的一侧为镜面，能够反射紫外光LED 2012射出的深紫外光，安装座2013的截面呈倒梯形，梯形的安装座2013能够改变光反射的角度；进一步地，光源板2011朝向光漫射组件202的一面还可以设有用于反射紫外光的镜面或反射膜层。在一个优选实施方式中，第一漫射结构203包括多个在第一板体2021入光面形成的凹槽2031，安装座2013一一对应容纳于凹槽2031中，光源板2011与第一板体2021之间的距离几乎为零，以减小整个紫外消毒部件20的厚度，光源板2011和光漫射组件202的第一板体2021之间的空间填充有氮气，以减少光损失。进一步地，凹槽2031的表面为曲面。
请同时参阅图2和图3所示，第二漫射结构204包括多个凸起2041，每个凸起2041上设有多个齿状件2042，凸起2041的表面为曲面。凹槽2031和凸起2041均呈条状，多个条状的凹槽2031依次排列，多个条状的凸起2041依次排列，凹槽2031的长度方向与凸起2041的长度方向垂直。每个凸起2041上的多个齿状件2042尖端的角度沿着齿状件2042的排列方向首先逐渐增加、然后逐渐减小，也就是说，在图3所示的A向视角，位于中间位置齿状件2042的尖端角度θ最大，从中间开始往两边延伸角度θ逐渐减小。
两个条状凸起2041的连接处设有从第一板体2021的出光面延伸至所述第二板体2022的入光面的柱状件206，柱状件206有个两个作用，一是起支撑作用，二是起导光作用，将光从第一板体2021的出光面直接导向第二板体2022的入光面，因为相邻两个条状的凸起2041之间的光较弱，采用上述方式这样直接导向第二板体2022，有利于第二板体2022对应处增加光强，提高光分布的均匀性。第三漫射结构205包括多个凸台2051，多个凸台2051均匀分布于第二板体2022的入光面，凸台2051能够进一步将光打散，同时增加光的射出概率。第二板体2022的出光面为一平坦表面，不易沉积灰尘，避免因第二板体2022出光面沉积灰尘导致光吸收增强的发生。
由于紫外线在空气中传播会导致紫外线损失，因此，第一板体2021和第二板体2022之间的空间呈真空状态，以减少两个板体之间光传输损失，增加光输出。第一板体2021和第二板体2022可以在真空氛围中采用熔融技术连接在一起。第一板体2021和第二板体2022由石英材料制成。
在图4所示的优选实施方式中，紫外消毒部件20还包括外框207，外框207呈阶梯状，紫外光源组件201固定于上方的高阶部，光漫射组件202固定于下方的低阶部。紫外光源组件201与外框207之间、以及光漫射组件202与外框207之间分别设有密封件2071，紫外光源组件201通过螺钉2072固定于外框207上。
另外，储藏装置本体10的底部还设有用于获得待储藏物品质量的重力感应器，重力 感应器可以设于冷却部件30上，门体102上设置有用于获得待储藏物品与门体201距离的距离感应器。储藏装置还包括一处理器，用于根据重力感应器所得待储藏物品质量和距离感应器所得待储藏物品与门体距离控制紫外光源组件所出射紫外光的剂量。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
