Description

一种可切换保鲜模式与杀菌模式的冰箱
技术领域
本发明属于冰箱技术领域，具体涉及一种可切换保鲜模式与杀菌模式的冰箱 。
背景技术
随着经济的发展和人们生活水平的不断提高，冰箱已走进千家万户，成为日常生活不可缺少的家用电器。冰箱是人为制造低温环境来保存食品的设备。早期的冰箱没有抗菌和杀菌的功能,仅仅依靠低温来保鲜食物,这种冰箱内的食品，尤其是冷藏室中的食品时间长了仍然腐败变质，这是因为在低温环境下仍然有细菌存在。后来人们在冰箱内胆里加入抗菌材料来进行杀菌,虽然有一定的效果,但是只能杀死与冰箱内壁接触的细菌,而冰箱内部的细菌无法杀死而冰箱内细菌大多附着在食物上,传统的杀菌装置很难碰及到上面，包括离装置较远的角落也是如此，那么有些局部或者空气中游离的细菌数量减少，但在冰箱角落或者食品表面细菌还在不断滋生并产生异味。
发明内容
本发明所要解决的技术问题是，提供一种控制灵活方便、食物冷藏效果更佳的可切换保鲜模式与杀菌模式的冰箱。
为解决上述技术问题，本发明采用的技术方案是： 一种可切换保鲜模式与杀菌模式的冰箱，其包括设于 冰箱内的离子发生器及用于控制离子发生器电压的控制系统，控制系统通过调整离子发生器的电压实现保鲜模式与杀菌模式的切换。
保鲜模式对应的输入电压为VL1，杀菌模式对应的输入电压为VL2，VL1的范围为1V-12V，VL2的范围为12V-24V。
保鲜模式对应的输出电压为VH1，杀菌模式对应的输出电压为VH2，VH1的范围为1kV-5kV，VH2的范围为5kV-10kV。
所述 离子发生器设置于冰箱箱内顶部或背部或嵌入到风冷冰箱风道盖板处。
控制系统控制离子发生器交替运行保鲜模式与杀菌模式。
与现有技术相比，本发明的有益效果是：
本发明采用了在冰箱控制板输出电压控制技术，从而通过离子发生器输入电压的改变来控制离子发生器的工作模式，因此，可以通过离子发生器电压值的变化来改变其电离能力，从而可以实现在冰箱保鲜功能与杀菌功能之间的切换。
附图说明
图 1 为本发明的整体结构示意图；
图 2 、图 3 为本发明的控制流程图；
图4为离子发生器工作原理图；
具体实施方式
下面结合具体实施方式对本发明作进一步的说明。其中， 本发明中提到了如下相关术语：
负离子：空气负离子，是指一个或一个以上的电子带负电荷的氧气离子。它是空气中的氧分子结合了自由电子而形成的。
电晕放电：导线或电极表面的电场强度超过碰撞游离阈值时发生的气体局部自持放电现象。电晕多发生在导体壳的曲率半径小的地方。
水分子团：自然界的水不是以单一水分子（H2O)的形式存在的，而是由若干水分子通过氢键作用而聚合在一起，形成水分子簇，俗称'水分子团'。
下面结合具体实施例对本发明作进一步的说明。
本发明公开一种可切换保鲜模式与杀菌模式的冰箱，其包括设于 冰箱内的离子发生器及用于控制离子发生器电压的控制系统，控制系统通过调整离子发生器的电压实现保鲜模式与杀菌模式的切换。
本发明提供一种新的冷藏室保鲜构思，即通过离子发生器保鲜模式与杀菌模式的切换，实现冰箱兼具保鲜与杀菌功能，具体是：保鲜模式下，通过离子发生器分解冷藏室内水分子团团聚结构，使水分子团变小，使其营养生理功能（如水的溶解力、渗透力、乳化力和扩散力等）越强，提升水分利用率，更好地保持营养物质，延长食物的保鲜时间；杀菌模式下，通过离子发生器电离空气产生正负离子，同时正负离子群混合在空间内，将细菌包围，正负离子群发生化学反应，产生活性物质羟基自由基（OH)或过氧化氢(H2O2)，所产生的活性物质将细菌的分子结构改变或能量转换，从而进行杀菌。
保鲜模式对应的输入电压为VL1，杀菌模式对应的输入电压为VL2，VL1的范围为1V-12V，VL2的范围为12V-24V。当然对于本领域的技术人员，很容易通过本实施例联想到其它实现输入电压变化的方法，因此，本发明的输入电压并不局限于所给定的两个范围。
保鲜模式对应的输出电压为VH1，杀菌模式对应的输出电压为VH2，VH1的范围为1kV-5kV，VH2的范围为5kV-10kV。
本发明的含有离子发生器可以设置在冰箱箱内顶部或背部或嵌入到风冷冰箱风道盖板处。图1展示了应用本装置的冰箱（上冷藏下冷冻两门冰箱），显然的，本发明不仅适用于上冷藏下冷冻两门冰箱，还适用于其它含有冷藏室的冰箱或冷柜等。所述冰箱包括离子发生器1、冷藏门体2、门封条3、为冷冻门体4、箱体5、冷藏层架6、冷藏抽屉7、冷冻层架8、冷冻抽屉9、压缩机10。
图2、图3为本发明的控制流程图，控制面板可以显示保鲜模式与杀菌模式，关于保鲜模式与杀菌模式的切换可以设置多种方式：
（1）保鲜模式与杀菌模式交替运行；
（2）系统默认运行保鲜模式，控制系统接受其他信号自动运行杀菌模式；
（3）系统默认运行保鲜模式，用户可以人为的切换到杀菌模式，从而实现保鲜模式与杀菌模式的切换。
图4为离子发生器的工作原理图。
保鲜模式启动时：
在保鲜模式下，离子发生器发射极能够产生电离作用并形成场效应，破坏空气中的水分子团的团簇结构，从而增强水分子的渗透力、溶解力，利于新鲜水果、蔬菜的吸收。水分子团簇结构的电离分解技术，自然界的水不是以单个分子（H2O）形态存在，而是由若干个水分子通过氢键作用聚合在一起，形成 水分子簇，即水分子团。因此，无论是在固态、液态还是气态，大多数水分子一般都以不同聚集度的缔合分子形式存在。通过设置水分子分离装置，从而破坏空气中的水分子团的团聚结构，达到水分子团变小的目的。水的分子团越小，则其营养生理功能（如水的溶解力、渗透力、乳化力、扩散力）越强，含氧量越高，随着无霜冰箱的冷风循环，可以将小的水分子团带到冰箱保鲜室，利于新鲜水果、蔬菜的吸收，提高冰箱保鲜效果的目的。由于此时输入电压控制在2kV，因此，保鲜模式下对空气的电离作用并不强，主要功能侧重在对空气中水分子团的影响。在保鲜模式作用下，离子发生器也会存在对空气的电离，也会有正负离子释放，但此种模式下，正负离子的浓度较低，不足以起到杀菌的目的，因此，保鲜模式下主要是以减小水分子团结构为主。
杀菌模式启动时：
杀菌模式下，离子发生器发射极对空气分子电离产生的正离子与负离子，在空气中进行正负电荷中和的瞬间会产生巨大的能量释放，导致其周围细菌的结构发生改变或能量的转换，从而致使细菌死亡，实现除菌的作用。由于风冷冰箱冷藏室存在风扇，强迫对流会增强离子发生器的杀菌效果。
