具体实施方式
下面将结合附图，对本公开一些实施例进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，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一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“连接”及其衍伸的表达。术语“连接”应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接相连，也可以通过中间媒介间接相连。这里所公开的实施例并不必然限制于本文内容。
A、B或C中的至少一个”包括以下A、B和C的组合：仅A，仅B，仅C，A和B的组合，A和C的组合，B和C的组合，及A、B和C的组合。
如本文中所使用，根据上下文，术语“如果”任选地被解释为意思是“当……时”或“在……时”或“响应于确定”或“响应于检测到”。类似地，根据上下文，短语“如果确定……”或“如果检测到[所陈述的条件或事件]”任选地被解释为是指“在确定……时”或“响应于确定……”或“在检测到[所陈述的条件或事件]时”或“响应于检测到[所陈述的条件或事件]”。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
如本文所使用的那样，“约”、“大致”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。
如本文所使用的那样，“平行”、“垂直”、“相等”包括所阐述的情况以及与所阐述的情况相近似的情况，该相近似的情况的范围处于可接受偏差范围内，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。
通常，在冰箱长期储存各种食品的过程中，冰箱内部容易滋生细菌，并且，细菌等微生物的繁殖导致冰箱内部产生异味。而冰箱内的细菌等微生物主要存在于冰箱内部的空气中以及物品表面。该物品表面包括冰箱材料的表面以及冰箱内食材的表面。对于冰箱内部的空气中细菌等微生物，可通过等离子杀菌方式以实现杀菌，或者，可以通过被动杀菌方式，以实现对冰箱的杀菌。例如，采用抗菌材料制造内胆、门把手或门封等。例如，所述抗菌材料包括纳米二氧化硅载银抗菌剂、纳米载银二氧化钛抗菌剂等。然而，只有当细菌等微生物接触到采用了抗菌材料制造的部件后，才可实现杀菌。在细菌等微生物未接触到采用了抗菌材料制造的部件的情况下，无法实现杀菌，从而采用抗菌材料的方案只能进行局部杀菌。
在一些方案中，对于物品表面的细菌等微生物，可以通过紫外线杀菌技术对物品表面进行杀菌，通过照射紫外线，可以破坏细菌等微生物的细胞壁、脱氧核苷酸等结构，以实现杀菌。例如，通过紫外线灯源、透光材料、反光材料、滤波器件等建立紫外线杀菌系统，实现对细菌等微生物的灭除。然而，紫外线对人体、食材以及冰箱内部材料等分别有危害，且紫外线杀菌技术的成本较高。另外，由于紫外线无法穿透包装材料(如，保鲜袋、保鲜盒、玻璃等)，这样，当冰箱内的食材具有包装材料时，紫外线的杀菌效率较低。
为了解决上述问题，本公开一些实施例提供了一种冰箱100。在该冰箱100中，利用短波蓝光透过食材的包装材料以对食材进行杀菌。并且，在该冰箱100中，可以根据门体和抽屉的开闭状态，控制杀菌装置的开闭，从而在提高杀菌效率的同时避免影响用户对冰箱100的使用。
图1为根据一些实施例的冰箱的结构图。
如图1所示，冰箱100包括箱体10。箱体10作为冰箱100的支撑结构，且箱体10包括一个或多个腔室101。一个或多个腔室101可以包括冷藏室、冷冻室或变温室。例如，如图1所示，一个或多个腔室101包括冷藏室1001和冷冻室1002。冷藏室1001与冷冻室1002沿箱体10的高度方向(如，图1中的上下方向)排布，且冷藏室1001位于冷冻室1002的上侧。
在一些实施例中，如图1所示，冰箱100还包括一个或多个门体200，门体200被配置为打开或者关闭对应的腔室101。
例如，在一个或多个腔室101包括冷藏室1001和冷冻室1002的情况下，一个或多个门体200包括第一子门体2001和第二子门体2002。第一子门体2001设置在冷藏室1001的开口处，且可枢转地打开或关闭冷藏室1001，第二子门体2002设置在冷冻室的1002开口处，且可枢转地打开或关闭冷冻室1002。
在一些实施例中，一个腔室101可以设有多个门体200。例如，如图1所示，冷藏室1001的开口处设有两个第一子门体2001。两个第一子门体2001分别朝靠近或远离彼此的方向转动，以关闭或打开冷藏室1001。
在一些实施例中，如图1所示，门体200包括第四壳体201、内胆202、第一侧板203、第二侧板204以及绝热层。第四壳体201位于箱体10的外侧。内胆202位于箱体10的内侧。第一侧板203设置在第四壳体201和内胆202的一侧(如上侧)，第二侧板204设置在第四壳体201和内胆202的另一侧(如下侧)。第四壳体201、内胆202、第一侧板203以及第二侧板204互相连接构成门体200。所述绝热层设置在第四壳体201、内胆202、第一侧板203以及第二侧板204围成的空间内。例如，所述绝热层由发泡材料填充而成。
图2为根据一些实施例的冰箱的制冷系统的结构图。
在一些实施例中，如图2所示，冰箱100还包括制冷系统20，制冷系统20设于箱体10内。制冷系统20被配置为提供冷量至腔室101，以使腔室101维持在预设温度。
在一些实施例中，如图2所示，制冷系统包括压缩机210、冷凝器220和蒸发器260。压缩机210 的入口与蒸发器260的出口连接，压缩机210的出口与冷凝器220的入口连接。压缩机210被配置为压缩冷媒以使低压冷媒受压缩形成高压冷媒。
在一些实施例中，如图2所示，制冷系统20还包括过滤器240和减压器250。过滤器240的入口与冷凝器220的出口连接，过滤器240的出口与蒸发器260的入口相连接。过滤器240被配置为过滤制冷剂中的杂物，如金属屑、灰尘等，以防止杂物堵塞减压器250。例如，过滤器240为干燥过滤器(Drier Filter)。干燥过滤器具有过滤功能和干燥功能。例如，干燥过滤器通过滤芯或滤网来阻止杂物颗粒进入系统，并使用物理吸附材料或分子筛等吸附或分离湿气分子。减压器250设于过滤器240的出口与蒸发器260的入口之间。
在一些实施例中，如图2所示，制冷系统20还包括气液分离器270。气液分离器270设于压缩机210的入口与蒸发器260的出口之间，气液分离器270用于将气态冷媒与液态冷媒进行分离，以避免因蒸发器260内的液态冷媒未完全蒸发，而产生的过湿气体进入压缩机210内，从而损坏压缩机210。
在一些实施例中，如图2所示，制冷系统还包括防凝管230，防凝管230位于冷凝器220与过滤器240之间。防凝管230可设于门体200的内边框处。且被配置为使门体200的温度升高，避免箱体10外部的水蒸气在门体200处遇冷而凝结为水珠。
在一些实施例中，制冷系统20还包括风机。所述风机被配置为使空气进入蒸发器260内，并将经过热交换的空气输送至对应的腔室101内。
制冷系统20的工作过程包括压缩过程、冷凝过程、节流过程和蒸发过程。
压缩过程包括：当冰箱100上电时，压缩机210开始工作。低温、低压的制冷剂被压缩机210吸入，在压缩机210的汽缸内被压缩成高温、高压的过热气态制冷剂后排出至冷凝器220中。
冷凝过程包括：高温、高压的过热气态制冷剂在冷凝器220中散热，被冷却为饱和液体，制冷剂在冷凝过程中的压力大致不变。
节流过程包括：所述饱和液体经过滤器240滤除水分和杂质后流入减压器250，通过减压器250进行节流降压，制冷剂变成低压的气液混合的两相态制冷剂(湿蒸气)。
蒸发过程包括：低压的湿蒸气在蒸发器260内吸热汽化，以降低蒸发器260及其周围环境的温度，并使制冷剂变成低压的气体。从蒸发器260排出的制冷剂经过气液分离器270后回到压缩机210中。
可以理解的是，制冷系统20通过重复执行以上过程，可以将冰箱100内的热量转移到冰箱100的外部，从而实现制冷。
图3为根据一些实施例的冰箱中储物装置的剖视图。
在一些实施例中，如图3所示，冰箱100还包括一个或多个储物装置50。储物装置50包括第一壳体1010。第一壳体1010与箱体10固定连接，且位于腔室101内。这里，储物装置50可以设于冷藏室1001或冷冻室1002内。
在一些实施例中，如图3所示，储物装置50还包括第一盖板1012和抽屉1011。第一盖板1012盖设在第一壳体1010上，以与第一壳体1010形成容纳抽屉1011的腔室，且该腔室靠近门体200的一侧敞开，以形成开口。抽屉1011设置在第一壳体1010内，且被配置为容纳食材300。
在一些实施例中，第一盖板1012和第一壳体1010可以为一体件。

如图4和图5所示，抽屉1011包括本体10111、把手10112和储物室10113。本体10111内容中空形成储物室10113，以用于储藏食材。把手10112设置在本体10111的靠近门体200的一侧(如图5中的前侧)。通过拉动或推动把手10112，可以将抽屉1011从所述腔室的开口处拉出或推入。
在一些实施例中，抽屉1011可以为桶式结构。例如，抽屉1011的靠近第一盖板1012的一侧(顶部)敞开。或者，抽屉1011也可以为盖板结构，第一盖板1012可以盖设于抽屉1011的顶部。
当然，在另一些实施例中，储物装置50也可以包括层架，所述层架与箱体10相连，食材300可以放置在所述层架上。
图6为为根据一些实施例的冰箱中另一种储物装置的剖视图。
在一些实施例中，如图6所示，储物装置50还包括出风口1020。出风口1020设于第一壳体1010上，且出风口1020被配置为对杀菌装置30进行散热，以提高杀菌装置30的工作寿命和杀菌效果。例如，如图6所示，第一壳体1010包括后背板1015，后背板1015为第一壳体1010的远离门体200的侧板，出风口1020设置在后背板1015上。
下面详细描述本公开一些实施例中的杀菌装置30。
在一些实施例中，如图3所示，冰箱100还包括杀菌装置30，杀菌装置30被配置为发出短波蓝光，以对存放在储物装置50内的食材300进行除菌。杀菌装置30可以可拆卸地设于第一盖板1012上，以垂直照射储物室10113。例如，杀菌装置30通过卡扣或螺丝与第一盖板1012相连。或者，杀菌装置30可以可拆卸地设置在所述层架的上方。例如，杀菌装置30可拆卸地设置在所述层架上方对应的箱体10上。当然，杀菌装置30也可以与第一盖板1012、第一壳体1010或箱体10为一体结构，本公开对此不作限定。
以下以杀菌装置30设置在第一盖板1012上为例进行示例性说明。
图7为根据一些实施例的一种杀菌装置的爆炸图。图8为根据一些实施例的第一盖板和杀菌装置的结构图。图9为图8中圈A的局部放大图。
在一些实施例中，如图7至图9所示，杀菌装置30包括第一基板37和光源部件33。光源部件33设于第一基板37上，且光源部件33被配置为发出短波蓝光。如图3所示，光源部件33的覆盖角度B为目标角度范围中的任一值，以使光源部件33发出的光线可直接照射位于储物室10113内的食材300的表面。所述目标角度范围可以为30°至120°。例如，覆盖角度B为30°、65°、90°、105°、或120°等。在该目标角度范围下，可以基本满足光源部件33发出的光线照射位于储物室10113内的食材300的表面。这里，覆盖角度B为光源部件33发出的光线的发散的角度。
在一些实施例中，如图7所示，光源部件33包括发光二极管(Lighting Emitting Diode，LED)3027。发光二极管3027可以发出短波蓝光。此时，覆盖角度B为发光二极管3027发出的短波蓝光的发散的角度。该短波蓝光的波长可以为目标波长范围内的任一值。例如，所述目标波长范围为400nm至480nm，或者，所述目标波长范围为400nm至420nm。该短波蓝光的波长可以为400nm、410nm、420nm、440nm、460nm、或480nm等。
例如，发光二极管3027发出的光线覆盖角度为30°至120°内的任一值，光源部件33的辐照度为0.01mW/cm2～10mW/cm2内的任一值。例如，光线覆盖角度为30°、45°、60°、90°或120°，光源部件33的辐照度为0.01mW/cm2、1mW/cm2、5mW/cm2、8mW/cm2或10mW/cm2。当光源部件33的辐照度小于0.01mW/cm2时，发光二极管3027发出的短波蓝光的辐射过小，杀菌效果低；当光源部件33的辐照度大于10mW/cm2时，发光二极管3027发出的短波蓝光的辐射过大，且浪费能量。
需要说明的是，紫外线的除菌原理为：紫外线直接照射微生物，导致微生物的脱氧核苷酸(Deoxyribonucleic Acid，DNA)复制转录中断，从而引起微生物死亡。短波蓝光的除菌原理与紫外线的除菌原理不同。短波蓝光的除菌原理为：微生物细胞内的卟啉化合物(Porphyrins)，在经过波长为所述目标波长范围的蓝光照射后，该卟啉化合物发生电子跃迁，产生羟基自由基、过氧化氢、或单线态氧等活性物质，该活性物质作用于微生物的细胞壁或细胞膜，导致微生物的不可逆氧化损伤。
另外，相比于离子、臭氧、紫外线、触媒等，短波蓝光的穿透性能较好，可以有效穿透常见包装材料，对储物室10113内部的食材300进行除菌，从而实现保鲜。
需要说明的是，发光二极管3027发射的光线可以有效穿透保鲜袋、保鲜盒、玻璃等包装材料。这样，在食材300具有包装材料的情况下，由于紫外线无法穿透包装材料，相对于紫外线杀菌，采用发光二极管3027进行杀菌的效率较高。因此，当储物室10113内存放食材300时，光源部件33可以对食材300及包装材料外表面进行除菌保鲜；当储物室10113内没有食材300时，光源部件33也可以通过照射对储物室10113内表面进行除菌，以保持冰箱100的健康和洁净。
在一些实施例中，如图7至图9所示，杀菌装置30还包括测距部件35。测距部件35设置在第一基板37上，且测距部件35被配置为检测储物室10113内的食材300与杀菌装置30之间的目标距离H。这里，目标距离H为食材300与杀菌装置30之间的最小距离。测距部件35可以为超声波测距传感器、激光测距仪或红外线测距传感器。
在一些实施例中，在测距部件35为超声波测距离传感器情况下，冰箱100还可以包括计时器。测距部件35的发射端发出声波信号，声波信号遇到食材300的阻挡后返回测距部件35的接收端。所述计时器从发射声波信号时开始计时，在接收到反射的声波信号后停止计时，根据所述计时器的计时时间t和声波信号在空气中的传播速度v，通过公式(1)可以计算目标距离H。
H＝v×t/2   (1)
在一些实施例中，如图7所示，杀菌装置30还包括散热器36。散热器36位于第一基板37的靠近 第一盖板1012的一侧(如，图7中的上侧)，且第一基板37与散热器36固定在第一盖板1012上。例如，杀菌装置30还包括连接孔38。第一基板37与散热器36通过连接孔38和螺栓配合固定在第一盖板1012上。散热器36可以为铝材质，以提高杀菌装置30的散热效果，且铝制散热器可以延长杀菌装置30的工作寿命。
在一些实施例中，如图7至图9所示，杀菌装置30还包括灯罩31和第一连接件34。灯罩31位于第一基板37的远离第一盖板1012的一侧(如，图7中的下侧)，且通过第一连接件34(如，卡扣)固定安装于第一基板37的外侧，以罩设光源部件33和测距部件35。
在一些实施例中，如图7至图9所示，杀菌装置30还包括密封件32。密封件32(如，密封胶条)设置在灯罩31内，以隔绝水汽，防止在水汽进入杀菌装置30内腐蚀光源部件33。
图10为根据一些实施例的一种冰箱中反光膜的示意图。
在一些实施例中，如图10所示，储物装置50还包括反光膜1013。反光膜1013设于抽屉1011的内表面10114。例如，反光膜1013设置在抽屉1011的本体10111的内壁面。反光膜1013可以为塑料材质，且反光膜1013包含反光材料。反光膜1013被配置为反射光源部件33发射的光线。例如，光源部件33发射的光线照射在反光膜1013上，光线发生反射和折射，形成反射光线1014以及折射光线。这样，光源部件33发射的光线可以均匀地覆盖抽屉1011的内部，避免光线垂直照射时无法完全覆盖储物室10113，提高光照的均匀性，增大光照的覆盖面积，提高光照杀菌的效果。
在一些示例中，如图10所示，抽屉1011的本体10111的内表面10114为凸面。例如，本体10111的内表面10114的一部分向本体10111的中心凸出，以形成所述凸面。这样，当光源部件33发射的光线照射到反光膜1013时，所述凸面可以对光线进行发散，从而提高光照杀菌的效果。
在一些实施例中，如图1所示，冰箱100还包括第一感应组件205，第一感应组件205设置在门体200与箱体10的连接处。第一感应组件205包括第一磁体和第一传感器2051。所述第一磁体可以位于冰箱100的铰链盒2052内。第一传感器2051设于门体200上，且与所述第一磁体对应。第一传感器2051被配置为检测第一传感器2051附近的第一磁场强度。
例如，当所述第一磁场强度小于第一设定值(如，10Gs)时，表明第一传感器2051与所述第一磁铁之间的距离较大，此时，第一传感器2051内开关的输出电平翻转，第一传感器2051停止运行，门体200打开。当所述第一磁场强度大于或等于第一设定值(如，10Gs)时，表明第一传感器2051与所述第一磁铁之间的距离较小，此时，第一传感器2051内开关的输出电平翻转，第一传感器2051运行，门体200关闭。
如图5所示，冰箱100还包括第二感应组件206，第二感应组件206设置在抽屉1011与第一壳体1010的连接处。第二感应组件206包括第二磁体2061和第二传感器2062。第二磁体2061设于第一壳体1010上。第二传感器2062设置在把手10112上。第二磁体2061和第二传感器2062对应。第二传感器2062被配置为检测第二传感器2062附近的第二磁场强度。
例如，当所述第二磁场强度小于第二设定值(如，10Gs)时，表明第二传感器2062与第二磁体2061之间的距离较大，此时，第二传感器2062内开关的输出电平翻转，第二传感器2062停止运行，抽屉1011打开。当所述第二磁场强度大于或等于第二设定值(如，10Gs)时，表明第二传感器2062与第二磁体2061之间的距离较小，此时，第二传感器2062内开关的输出电平翻转，第二传感器2062运行，抽屉1011关闭。
这里，所述第一磁体和第二磁体2061可以为永磁铁。第一传感器2051和第二传感器2062可以为霍尔传感器。
需要说明的是，第一感应组件205和第二感应组件206也可以在冰箱100的其他位置。另外，也可以通过其他传感器检测门体200的状态和抽屉1011的状态，所述第一设定值和所述第二设定值也可以为0或者其他数值。本公开对此不作限定。这里，门体200的状态是指门体200的开启和关闭状态；抽屉1011的状态是指抽屉1011的开启和关闭状态。抽屉1011的开启状态为抽屉1011从第一壳体1010内被拉出的状态；抽屉1011的关闭状态为抽屉1011处于第一壳体1010内的状态。
图11为根据一些实施例的另一种冰箱的结构图。
在一些实施例中，如图11所示，冰箱100还包括控制器40。控制器40设于箱体10内。制冷系统20和杀菌装置30分别与控制器40电连接。例如，杀菌装置30还包括连接线，该连接线与控制器40电连接。控制器40被配置为控制杀菌装置30执行杀菌工作。
控制器40包括中央处理器、微处理器(Microprocessor)、专用集成电路(Application Specific Integrated Circuit,ASIC)，并且可以被配置为当处理器执行存储在控制器40的非暂时性计算机可读介质中的程序时，执行控制器40中描述的相应操作。
在一些实施例中，控制器40被配置为：根据门体200的状态和抽屉1011的状态，控制杀菌装置30开启或关闭，并根据目标距离H确定相应的光照强度等级，以控制杀菌装置30根据确定的光照强度等级进行杀菌。
例如，第一传感器2051和第二传感器2061与控制器40电连接，控制器40可根据第一传感器2051和第二传感器2061传输的信号，判断门体200是否开启和抽屉1011是否开启。测距部件35与控制器40电连接，测距部件35检测目标距离H，并将目标距离H等参数发送至控制器40，控制器40根据目标距离H确定相应的光照强度等级，从而控制杀菌装置30根据相应的光照强度等级进行杀菌。
在本公开一些实施例中，杀菌装置30安装于抽屉1011的上方，这样，杀菌装置30发出的短波蓝光可以照射整个储物室10113，以对食材300进行杀菌，从而提高杀菌的效率，避免损害食材300及冰箱100内的材料，且可以避免对人体健康产生危害。控制器40根据测距部件35检测的目标距离H，调节光照强度等级，可以实现良好的杀菌性能。另外，杀菌装置30拆装方便，无需改变储物装置50的结构，即可直接将杀菌装置30设置在盖板上，且成本较低。
以下结合图12至图14对控制器40执行的步骤进行详细说明。
图12为根据一些实施例的控制器执行步骤的流程图。
在一些实施例中，如图12所示，控制器40被配置执行步骤11至步骤14。
在步骤11中，获取门体200的状态和抽屉1011的状态。
在步骤12中，在门体200开启，抽屉1011关闭的情况下，控制杀菌装置30开启第一预设时间后关闭。
例如，所述第一预设时间为30s至60s内的任一值。例如，所述第一预设时间为30s、45s或60s。在门体200开启，抽屉1011关闭的情况下，当杀菌装置30开启的时间小于30s时，控制器40关闭杀菌装置30，杀菌装置30的开启时间过短，杀菌效果较低。
在步骤13中，在门体200关闭，抽屉1011关闭的情况下，控制杀菌装置30开启。
在步骤14中，在门体200开启，抽屉1011开启的情况下，控制杀菌装置30关闭。
在一些实施例中，控制器40还被配置为：在杀菌装置30开启的情况下，控制杀菌装置30以第一模式或第二模式进行杀菌。在第一模式下，控制器40控制光源部件33间歇照射；在第二模式下，控制器40控制光源部件33持续照射第二预设时间后停止。
第一模式用于满足日常物品储存过程中的杀菌及保鲜需求。第二模式用于对新放入的物品或已经有变质状况的物品进行快速杀菌，从而满足用户短时间内想食用物品的需求。在第一模式下，光源部件33间歇照射；在第二模式下，光源部件33持续照射。需要说明的是，在第二模式运行完后，控制器40控制杀菌装置30切换至第一模式，以满足日常使用中物品的杀菌及保鲜需求。
需要说明的是，抽屉1011或门体200上可以设置控制面板。在控制面板上设置有按键，在按下按键后，可以控制杀菌装置30可以进入第二模式。
在一些实施例中，所述第二预设时间可以为1h至2h范围内的任一值。例如，第二预设时间为1h、1.5h或2h。当杀菌装置30进入第二模式小于1h时，杀菌装置30的杀菌效果较低；当杀菌装置30进入第二模式大于2h时，食材300的表面的细菌等微生物已经较少，继续以第二模式杀菌的效率较低。
需要说明的是，在门体200开启，抽屉1011关闭的情况下，控制器40可以控制杀菌装置30进入第二模式，且光源部件33持续照射时间不受所述第二预设时间的限制，例如，控制器40控制光源部件33持续照射所述第一预设时间。
在一些实施例中，控制器40还被配置为：在杀菌装置30开启时，根据目标距离H，确定光照强度等级。
图13为根据一些实施例的控制器执行步骤的另一种流程图。
在杀菌装置30开启时，控制器40需要确定光照强度等级。在此情况下，如图13所示，步骤12包括步骤121至步骤123，步骤13包括步骤131至133。
在步骤121中，确定门体200关闭，抽屉1011关闭。
在步骤122中，获取目标距离H，并根据目标距离H，确定光照强度等级。
在步骤123中，控制杀菌装置30以确定的光照强度等级开启第一预设时间后关闭。
在步骤131中，确定门体200开启，抽屉1011关闭。
在步骤132中，获取目标距离H，并根据目标距离H，确定光照强度等级。
在步骤133中，控制杀菌装置30以确定的光照强度等级开启。
图14为根据一些实施例的控制器执行步骤的另一种流程图。
在一些实施例中，如图14所示，在步骤122和步骤132之前，控制器40还被配置为执行步骤17和步骤18。
在步骤17中，根据预设距离范围和目标公式，确定光照强度范围。
所述预设距离范围为预先设置的目标距离H处于的范围，所述光照强度范围为对应预设距离范围的光照强度E处于的范围。
所述目标公式为：
E＝aH4-bH3+cH2+dH+e   (2)
a、b、c、d、e分别为常数。目标距离H的单位为cm，光照强度E的单位为mW。
需要说明的是，在光照强度为固定值的情况下，食材300受到的光辐射的能量与目标距离H呈反比。当食材300与光源部件33距离较大时，食材300受到的光辐射的能量较小，需增加光照强度E，以提高光辐射从而实现杀菌；当食材300光源部件33距离较小时，食材300受到的光辐射的能量较大，此时，可以减小光照强度E，以节约能耗。因此，为了使食材受到的光辐射满足需求，预设距离范围可以与光照强度E成正比。
在一些实施例中，a＝0.001、b＝0.039、c＝0.505、d＝2.539、e＝2.21。
在步骤18中，根据所述预设距离范围和所述光照强度范围，确定一个或多个预设距离区间，以及所述预设距离区间对应的光照强度等级。
在根据所述目标公式(2)计算得到相应的光照强度范围后，控制器40根据所述预设距离范围以及所述光照强度范围，设定预设距离区间以及所述预设距离区间对应的光照强度等级。
例如，在所述预设距离范围为0至20cm的情况下，控制器40根据目标公式(2)确定对应的光照强度范围。在此情况下，若以5cm作为一个预设距离区间的上限或下限，则控制器40可以设定一个预设距离区间为0至5cm，并且将该预设距离区间对应的光照强度范围(如，0＜E≤23mW)确定为一级光照强度等级。以此类推，确定出其他的预设距离区间和光照强度等级。
在一些实施例中，控制器40还被配置为：在杀菌装置30处于第一模式的情况下，若目标距离H大于0，且小于或等于第一阈值H1(0＜H≤H1)，确定光照强度等级为一级光照强度等级；若目标距离H大于第一阈值H1，且小于或等于第二阈值H2(H1＜H≤H2)，确定光照强度等级为二级光照强度等级；若目标距离H大于第二阈值H2，且小于或等于第三阈值H3(H2＜H≤H3)，确定光照强度等级为三级光照强度等级；若目标距离H大于第三阈值H3，且小于或等于第四阈值H4(H3＜H≤H4)，确定光照强度等级为四级光照强度等级。
在一些实施例中，控制器40还被配置为：在杀菌装置30处于第二模式的情况下，若目标距离H大于0，且小于或等于第一阈值H1(0＜H≤H1)，确定光照强度等级为一级光照强度等级；若目标距离H大于第一阈值H1，且小于或等于第二阈值H2(H1＜H≤H2)，确定光照强度等级为二级光照强度等级；若目标距离H大于第二阈值H2，且小于或等于第三阈值H3(H2＜H≤H3)，确定光照强度等级为三级光照强度等级；若目标距离H大于第三阈值H3，且小于或等于第四阈值H4(H3＜H≤H4)，确定光照强度等级为四级光照强度等级。
需要说明的是，光照强度等级越高，光照强度越大，食材300在单位面积上接收到的光能量越大，杀菌装置30的杀菌效果越好；光照强度等级越低，光照强度越小，食材300在单位面积上接收到的光能量越小，杀菌装置30的杀菌效果越弱。
另外，由于预设距离范围与光照强度E成正比，因此，预设距离范围与光照强度等级成正比。也就是说，预设距离范围越小，对应的光照强度等级越小；预设距离范围越大，对应的光照强度等级越大。
需要说明的是，光照强度等级也可以分为一个、两个、三个或更多个光照强度等级，本公开对此不做限制。
在一些实施例中，在光源部件33包括多个发光二极管3027的情况下，多个发光二极管3027可以并联，且分别对应储物室10113内不同的区域。此时，控制器40还被配置为：根据不同区域对应的目 标距离H，分别调整相应区域内发光二极管3027的光照强度。
图15为根据一些实施例的储物装置中储物室的光照区域的示意图。
如图15所示，储物室10113包括多个子区域。所述多个子区域包括第一区域1016、第二区域1017、第三区域1018、以及第四区域1019，控制器40根据该四个区域内的目标距离H，分别控制四个区域内的发光二极管3027，调整不同区域内的光照强度E，以对抽屉1011内不同高度的食材300进行杀菌。
需要说明的是，在储物室10113包括不同的区域的情况下，杀菌装置30可以包括多个测距部件35，以便检测不同区域对应的目标距离H。例如，在将储物室10113划分为四个不同的区域的情况下，杀菌装置30可以设置四个测距部件35，以检测四个区域内的目标距离H。
前文主要以控制器40根据杀菌装置30与食材300之间的目标距离控制光源部件33的光照参数为例进行说明。当然，在一些实施例中，控制器40也可以根据食材300的其他参数调整光源部件33的光照参数。在此情况下，杀菌装置30的结构可以与上述杀菌装置的结构不同。
在一些实施例中，如图6所示，杀菌装置30设于第一壳体1010的远离门体200的一侧板(如，后背板1015)上，且靠近第一盖板1012。
在一些实施例中，杀菌装置30可以与后背板1015为一体件，且与出风口1020连通，以提高杀菌装置30的散热效果。
图16为根据一些实施例的冰箱中另一种杀菌装置的结构图。图17为根据一些实施例的杀菌装置的剖视图。
在一些实施例中，如图16所示，杀菌装置30包括第二壳体43和灯罩31。灯罩31盖设在第二壳体43上，以封闭第二壳体43内的容纳空间。例如，杀菌装置30还包括第二连接件45和第三连接件46。第二连接件45设于第二壳体43上，第三连接件46设于灯罩31上，且第二连接件45与第三连接件46固定连接(如卡接)，以使灯罩31固定在第二壳体43上。
在一些实施例中，如图16和图17所示，杀菌装置30还包括光源部件33和图像识别组件41。光源部件33和图像识别组件41位于该容纳空间内。光源部件33的结构和功能可参见前文的相关描述，在此不再赘述。图像识别组件41被配置为识别储物室10113内的食材300的图像信息。
在一些实施例中，杀菌装置30还包括第二基板39。光源部件33和图像识别组件41设置在第二基板39上。例如，光源部件33通过焊接固定在第二基板39上。图像识别组件41通过固定件(如，螺丝)固定在第二基板39上。需要说明的是，在一些示例中，光源部件33和图像识别组件41也可以分别集成在第二基板39上。
在一些实施例中，图像识别组件41可以设于第二基板39的中间位置，以提高图像识别的范围和图像识别准确度。
在一些实施例中，杀菌装置30还包括散热器36，散热器36设置在第二基板39的远离光源部件33的一侧，且第二基板39与散热器36连接。通过散热器36可以提高杀菌装置30的散热效果，延长杀菌装置30的工作寿命。例如，散热器36为铝板，并通过固定件(如，螺栓)设于第二基板39上。
在一些实施例中，如图16和图17所示，杀菌装置30还包括电机42、转动轴49和联轴器48。电机42的第一端固定安装在第二壳体43的内侧壁上，电机42的第二端通过联轴器48与转动轴49连接。转动轴49与散热器36相连。电机42被配置为驱动转动轴49旋转，以带动光源部件33转动从而调节光源部件33的照射角度。
例如，如图16和图17所示，杀菌装置30还包括第一配合部44和第二配合部47。第一配合部44设于转动轴49上，第二配合部47设于散热器36上。第一配合部44与第二配合部47相连接，以传递扭矩。电机42通过驱动联轴器48，以带动转动轴49转动，转动轴49带动散热器36和第二基板39转动，以调整光源部件33的照射角度，从而实现对不同位置的食材300进行杀菌。例如，转动轴49的可旋转角度为0～90°，以满足光源部件33对食材300的照射。
需要说明的是，光源部件33、图像识别组件41、电机42分别与控制器40电连接，从而控制器40可以控制杀菌装置30运行。
以下以图16所示的杀菌装置30为例介绍控制器40执行的步骤。
图18为根据一些实施例的控制器执行步骤的又一种流程图。图19为根据一些实施例的另一种的储物装置的结构图。
在一些实施例中，如图18所示，控制器40被配置为执行步骤21至步骤23。
在步骤21中，根据图像识别组件41识别的食材300的图像信息，确定储物室10113内所存放的食材300的位置和包装材料的类型。
如图19所示，储物室10113内所存放的食材300的位置可以由图像识别组件41到食材300之间的连线与水平方向的第一夹角α进行表征。需要说明的是，由于图19仅显示了杀菌装置30，因此，以从杀菌装置30到食材300之间的连线表示图像识别组件41到食材300之间的连线。
在步骤22中，根据食材300的位置，确定光源部件33的照射角度，并控制电机42驱动光源部件33转动至所述照射角度。
例如，控制器40根据第一夹角α，确定杀菌装置30的照射角度β。如图19所示，照射角度β可以指光源部件33的中心点到食材300之间的连线与水平方向的第二夹角。需要说明的是，由于图19仅显示了杀菌装置30，因此，以从杀菌装置30到食材300之间的连线表示光源部件33的中心点到食材300之间的连线。并且，由于图像识别组件41的位置与于光源部件33的中心点相对应，因此，照射角度β与第一夹角α的大小相等。
在一些实施例中，不同的第一夹角α对应不同的照射角度β。例如，第一夹角α包括N个预设范围，照射角度β包括N个预设值，第一预设范围与第一预设值对应，第二预设范围与第二预设值对应，以此类推第N预设范围与第N预设值对应。这里，N大于或等于1，且N为自然数。
当控制器40确定第一夹角α处于第一预设范围时，控制器40确定光源部件33的照射角度β为第一预设值。在此情况下，控制器40控制电机42驱动联轴器48以带动第二基板39转动，从而调整照射角度β达到第一预设值。
在一些示例中，第一夹角α包括三个预设范围，且照射角度β包括三个预设值。第一预设范围为0～30°、第二预设范围为30°～60°，第三预设范围为60°～90°。第一预设值为30°、第二预设值为45°以及第三预设值为60°。
图20为根据一些实施例光源部件的照射角度的示意图。
例如，如图20所示，当第一夹角α小于30°(0°≤α<30°)时，控制器40调节光源部件33的照射角度β为30°；当第一夹角α大于或等于30°，小于或等于60°(30°≤α≤60°)时，控制器40调节光源部件33的照射角度β为45°；当第一夹角α大于60°，且小于或(60°＜α≤90°)时，控制器40调节光源部件33的照射角度β为60°。
在步骤23中，根据所述包装材料的类型，确定光源部件33的光照参数，并控制光源部件33按照所述光照参数运行。
所述光照参数包括光照时长和光照强度至少一种，控制器40根据食材300的包装材料的类型，确定光源部件33的光照参数，使光源部件33发出的光线可以穿透包装材料，以对包装材料内部的食材300进行有效杀菌。
在本公开一些实施例中，当需要对冰箱100内所存放的食材300进行杀菌时，通过冰箱100上的控制面板向控制器40发出杀菌指令。例如，控制面板包括语音交互装置、触摸屏或物理按键中的至少一种。控制器40收到所述杀菌指令后，控制器40被配置为响应杀菌指令，控制杀菌装置30开启，控制图像识别组件41获取其探测视野内食材300的图像信息，并发送至控制器40，控制器40根据该图像信息，确定储物室10113内所存放的食材300的位置，并确定食材300的包装材料的类型。控制器40根据食材300的位置，确定光源部件33的照射角度β，并控制电机42驱动光源部件33转动，以调整光源部件33的转动至确定的照射角度β。另外，控制器40根据包装材料的类型，确定光源部件33对食材300进行杀菌所需运行的光照参数，并控制光源部件33按照所述光照参数运行。
本公开一些实施例提供的冰箱100通过采用可见短波蓝光对储物室10113及储物室10113内存放的食材300进行杀菌，可以有效灭除食材300的包装材料的表面或食材300表面的微生物，还可以穿透包装材料，以对包装材料内部的食材300进行除菌，提高冰箱100的保鲜效果，且避免对食材300、储物室10113的材料以及人体造成有害影响。并且，控制器40控制图像识别组件41识别食材300的位置和包装材料的类型，控制电机42调整光源部件33的照射角度β，可以提高短波蓝光对食材300的覆盖面积，并通过调节光源部件33的光照参数，以使短波蓝光有效透过包装材料，以对包装材料内部的食材300进行杀菌，提升保鲜效果，另外，无需改变储物室10113的主体结构，杀菌装置30安装在后背板1015的靠近第一盖板1012的一侧(如，上侧)，方便对杀菌装置30的拆卸与安装。
图21为根据一些实施例的图像识别组件的框图。
在一些实施例中，如图21所示，图像识别组件41包括图像采集部件412和图像分类器413。例如，图像采集部件412为摄像机、监控器等。
对于图像分类器413，预先获取多个包含食材300的包装材料的图像作为训练数据集，对初始的图像分类器413进行训练，通过不断的参数更新和学习，训练得到可以识别包装材料的类型的图像分类器413。图像采集部件412拍摄冰箱储物室10113内的图像信息，图像分类器413将所述图像信息进行特征提取，将提取的特征信息作为所述训练完成的图像分类器413的输入值，经过图像分类器413的计算和分类，得到其输出的包装材料类型。例如，图像分类器413包括近邻分类器、支持向量机等。
图22为根据一些实施例的控制器执行步骤的又一种流程图。
在此情况下，如图22所示，步骤21包括步骤211至步骤213。
在步骤211中，控制图像采集部件412拍摄食材300的图像信息；
在步骤212中，控制图像采集部件412发送食材300的图像信息至图像分类器413；
在步骤213中，控制图像分类器件413对食材300的图像信息进行计算，以确定食材300的包装材料的类型。
图23为根据一些实施例的控制器执行步骤的又一种流程图。
在一些实施例中，图像识别组件41为红外线传感器，在此情况下，如图23所示，步骤21包括步骤214。
在步骤214中，根据所述红外线传感器识别的图像信息，确定所述储物室10113内所存放的食材300的包装材料的类型。
例如，预先建立图像信息中所包含的光学参数与包装材料类型的对应关系，通过红外线传感器识别冰箱储物室内的红外图像信息，以分析得到所存放的食材300的包装材料类型。这里，红外图像信息包括热辐射信息(如，包装材料的热量分布)或者温度信息(如，包装材料的外表面的温度)等。
图24为根据一些实施例的控制器执行步骤的又一种流程图。
在一些实施例中，如图24所示，在所述光照参数包括光照时长的情况下，步骤23包括步骤231至步骤233。
在步骤231中，根据食材300的包装材料的类型，确定包装材料的透光率。
需要说明的是，包装材料的透光率可以预先进行测定，并将测定的包装材料的透光率与包装材料的对应关系输入相关存储器内。控制器40可以读取存储器内存储的相关数据，并根据食材300的包装材料的类型，确定包装材料的透光率。
在步骤232中，根据预设的透光率与光照时长的对应关系，确定光照时长。
需要说明的是，透光率与光照时长的对应关系可以预先输入相关存储器内。控制器40可以读取存储器内存储的相关数据，根据预设的透光率与光照时长的对应关系，确定光照时长。包装材料的透光率与光照时长呈负相关。
在步骤233中，控制光源部件33运行光照时长。
在一些实施例中，所述包装材料的类型包括第一类型、第二类型、第三类型以及第四类型。第一类型包装材料的透光率在第一范围内、第二类型包装材料的透光率在第二范围内，第三类型包装材料的透光率在第三范围内。例如，所述第一类型为保鲜膜、保鲜袋等。所述第二类型为玻璃瓶、玻璃杯等。所述第三类型为透明度较好的塑料盒、塑料袋等。所述第四类型为透明度较差的黑色塑料袋、黄色塑料袋等。例如，所述第一范围为90％至100％；所述第二范围为80％至90％；所述第三范围为70％至80％；所述第四范围为0至70％。
这样，所述光照时长对应第一时长范围、第二时长范围以及第三时长范围。例如，所述第一时长范围为10min～20min，所述第二时长范围为20min～40min，所述第三时长范围为40min～60min。
在此情况下，若所述包装材料的透光率在第一范围(所述透光率大于或等于90％，且小于或等于10％)内，确定所述光照时长为第一时长范围内的任一值；若所述透光率为在第二范围(所述透光率大于或等于80％，且小于90％)内，确定所述光照时长为第二时长范围内的任一值；若所述透光率在第三范围(所述透光率大于或等于70％，且小于80％)内，确定所述光照时长为第三时长范围内的任一值。
这里，所述包装材料的所述透光率越小，控制器40控制光源部件33运行的时长越长。例如，若控制器40确定所述包装材料为所述第一类型，则控制光源部件33运行第一时长范围；若控制器40确定所述包装材料为所述第二类型，则控制光源部件33运行第二时长范围；若控制器40确定所述包装材料 为所述第三类型，则控制光源部件33运行第三时长范围；若控制器40确定所述包装材料为第四类型，即所述包装材料的透光率小于70％，则控制器40控制光源部件33保持常开。
需要说明的是，以上场景仅作为举例，可以根据实际需求，根据包装材料的透光率对包装材料的类型进行其他划分，并确定对应的光照时长，形成所述透光率与光照时长的对应关系，本公开对此不作限定。
图25为根据一些实施例的控制器执行步骤的又一种流程图。
在一些实施例中，如图25所示，在所述光照参数包括光照强度的情况下，步骤23包括步骤234至步骤236。
在步骤234中，根据食材300的包装材料的类型，确定包装材料的透光率。
在步骤235中，根据预设的透光率与光照强度的对应关系，确定光照强度。
在一些实施例中，预设设置透光率与光照强度的对应关系。透光率与光照强度的对应关系可以预先输入相关存储器内。控制器40可以读取存储器内存储的相关数据，根据预设的透光率与光照强度的对应关系，确定光照强度。所述包装材料的透光率越大，短波蓝光越容易穿透所述包装材料，以对所述包装材料内部的食材300进行除菌，从而所述光照强度可以较小；所述包装材料的透光率越小，短波蓝光越难以穿透所述包装材料，以对所述包装材料内部的食材300进行除菌，从而所述光照强度可以较大。因此，所述包装材料的透光率与所述光照强度呈负相关关系。
在步骤236中，控制光源部件33以所述光照强度照射。
例如，控制器40控制光源部件33发出具有确定的光照强度的光线。
图26为根据一些实施例的控制器执行步骤的又一种流程图。
在一些实施例中，在所述光照参数包括光照强度以及光照时长的情况下，如图26所示，步骤23包括步骤231至步骤236。
在本公开一些实施例中，控制器40根据包装材料的透光率，以确定光源部件33的光照强度和光照时长，从而提高光源穿透包装材料的效果，以对包装材料内部的食材进行有效除菌，从而提升对食材300的保鲜效果。
需要说明的是，步骤11至步骤14、步骤121至步骤123、步骤131至步骤133、以及步骤17至步骤18也可以应用于图16中的杀菌装置30，此时，图16中的杀菌装置30还可以包括测距部件35，该测距部件35可以设置在杀菌装置30的第二基板39上，以检测杀菌装置30与食材300之间的目标距离H。
