本发明涉及冷藏冷冻技术领域，特别是涉及一种冰箱及其玻璃面板。
背景技术
为了便于用户在冰箱外观察内部的储物情况，现有技术中出现了具有透明门体的冰箱。然而这种方式无法调节透明门体的透光性，因此可能导致储物室内部杂乱的储物情况影响外箱的整体外观效果，用户体验感也不强。
发明内容
本发明的一个目的旨在克服现有技术中的至少一个缺陷，提供一种能够调节门体透光性的冰箱。
本发明一个进一步的目的是要通过操作面板实现控制液晶视膜透明状态。
特别地，本发明提供了一种用于冰箱门体的玻璃面板，包括：玻璃罩体；液晶视膜，夹设于玻璃罩体的内部，液晶视膜配置成在通电状态下，使其内部的液晶聚合物的液晶分子呈有序状态，进而使得液晶视膜呈透明状态，在断电状态下，使液晶聚合物的液晶分子呈无序状态，进而使得液晶视膜呈非透明状态。
可选地，液晶视膜还包括液晶层和两个导电层，两个导电层相对设置，液晶层设置在两个导电层之间，并且液晶层填充有液晶聚合物。
可选地，玻璃面板还包括：供电板，以与两个导电层形成供电回路；控制器，与供电板电连接，以控制供电回路通断，进而控制液晶聚合物在有序状态与无序状态之间切换。
可选地，玻璃面板还包括：操作面板，设置于玻璃罩体上，并与控制器相连，以接收用户对供电板的通断指令。
可选地，液晶层具有状态显示区，供电板配置成控制状态显示区内的液晶聚合物以无序状态呈现出状态标识；控制器与冰箱的主控板电连接，以获取冰箱的运行状态，并发送至供电板，以使供电板控制状态显示区内的液晶聚合物，进而显示出对应的状态标识。

根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明

具体实施方式
在本实施例的描述中，需要理解的是，术语“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“进深”等指示的方位或位置关系为基于正常使用状态下的方位作为参考，并参考附图所示的方位或位置关系可以确 定，例如指示方位的“前”指的是朝向用户的一侧。这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。
参见图1，图1是根据本发明一个实施例的冰箱1的示意性截面图。本发明提供一种冰箱1，该冰箱1一般性地包括箱体10和门体20。
箱体10可包括外壳和多个内胆，外壳位于整体冰箱的最外侧，以保护整个冰箱1。多个内胆被外壳包裹，并且多个内胆与外壳之间的空间中填充有保温材料(形成保温层)，以降低内胆向外散热。每个内胆可以限定出向前敞开的主储物空间，并且主储物空间可以被配置成冷藏室、冷冻室、变温室等等，具体的主储物空间的数量和功能可以根据预先的需求进行配置。
门体20的数量还可与内胆的数量一致，即每个内胆向前敞开的主储物间室12均可由其对应的门体20进行开闭。门体20可动地设置于箱体10的前方，例如门体20可以通过铰接的方式设置箱体10前部的一侧，通过枢转的方式开闭主储物空间。
在一些实施例中，该门体20为单独部件，以开闭主储物间室12。参见图2，图2是根据本发明另一个实施例的冰箱1的示意性截面图。在另外一些实施例中，该门体20还可包括主门22和副门24。其中主门22设置于箱体10的前侧，以开闭主储物间室12。并且主门22上限定出向前敞开的门体储物间室22a，副门24设置在主门22的前方，以开闭该门体储物间室22a。
在一些实施例中，该冰箱1还可包括玻璃面板30。在采用独立门体20的实施例中，该玻璃面板30可直接设置在该门体20前部中央，用户无需打开门体20就可以直接通过其观察到存放在主储物间室12内的储物情况。在采用主门22、副门24的实施例中，该玻璃面板30可设置在副门24的前部中央，用户无需打开副门24就可以直接通过其观察到存放在门体储物间室22a内的储物情况。
参见图3a和图3b，图3a和图3b是根据本发明一个实施例的冰箱1中玻璃面板30的结构示意图，其中分别示出了处于通电状态和处于断电状态的玻璃面板30。在一些实施例中，该玻璃面板30可包括玻璃罩体310和液晶视膜320。液晶视膜320夹设于玻璃罩体310的内部，液晶视膜320内部具有液晶聚合物。该液晶视膜320在通电状态下，液晶聚合物的液晶分子在电场力的作用下会呈有序状态，进而使得液晶视膜320呈透明状态。该液晶视膜320在断电状态下，液晶分子呈无序状态，进而使得液晶视膜320呈非透明状态。
液晶聚合物(liquid crystal polymer，LCP)是介于固体结晶和液体之间的中间状态聚合物，其液晶分子的排列虽然不像固体晶态那样三维有序，但也不是液体那样无序，而是具有一定(一维或二维)的有序性。
参见图3a，当液晶聚合物处于电场力的作用下，液晶分子克服彼此之间的吸引力，从无序状态转化为有序状态，增大了液晶分子间距，玻璃罩体310一侧的光线能够轻易地通过液晶视膜320达到另外一侧，也即实现了液晶视膜320在通电状态下，液晶视膜320呈透明状态。
参见图3b，当液晶聚合物未处于电场力的作用下(不受外界干扰)，根据熵增原理，液晶分子重新回到一种无序状态，减小了液晶分子间距，玻璃罩体310一侧的光线也就无法轻易地通过液晶视膜320达到另外一侧，也即实现了液晶视膜320在断电状态下，液晶视膜320呈非透明状态。
由此可见，本实施例的冰箱1中，由于液晶视膜320夹设于玻璃罩体310的内部，并且液晶视膜320在通电状态下呈透明状态，液晶视膜320在断电状态下呈非透明状态，因此，用户可以根据实际情况自行调节液晶视膜320的透光性，既满足了用户无需开门就能够观察到储物情况的需求，又能在不需要观察的时候实现非透视，提高了用户的体验感。
参见图3a和图3b，在一些实施例中，液晶视膜320还可包括液晶层322和两个导电层324，两个导电层324相对设置，液晶层322设置在两个导电层324之间，并且液晶层322填充有液晶聚合物。
两个导电层324相对设置，当液晶视膜320通电后，两个导电层324之间形成电场，处于两个导电层324之间的液晶聚合物处于该电场中，以使得在电场力的作用下克服液晶聚合物的液晶分子彼此之间的吸引力，进而使得液晶分子从无序状态转化为有序状态，液晶视膜320呈现出透明状态。
参见图4，图4是根据本发明一个实施例的冰箱1的工作原理框图。该玻璃面板30还可包括供电板330和控制器340，供电板330与两个导电层324形成供电回路。控制器340与供电板330电连接，以控制供电回路通断，进而控制液晶聚合物在有序状态与无序状态之间切换。
供电板330可从冰箱1的主电源上取电，并且供电板330向供电回路提供12V直流电。控制器340可以为单片机或者PLC控制器。在供电回路中还可增加继电器实现控制供电回路通断。
参见图4，在一些具体的实施例中，玻璃面板30还可包括操作面板350，操作面板350设置于玻璃罩体310上，操作面板350与控制器340电连接，操作面板350接收用户对供电板330的通断指令，并将该通断指令转换成电信号发送给控制器340，控制器340接收到该电信号后将对应的通断指令发送给继电器，以控制供电回路通断。
例如，该操作面板350上具有“透明”按钮和“非透明”按钮，用户可根据实际情况操作对应的按钮控制液晶视膜320。
参见图5，图5是根据本发明一个实施例的冰箱1中玻璃面板30的使用状态参考图。液晶 层322具有状态显示区，供电板330配置成控制状态显示区内的液晶聚合物以无序状态呈现出状态标识。控制器340与冰箱1的主控板60电连接，以获取冰箱1的运行状态，并发送至供电板330，以使供电板330控制状态显示区内的液晶聚合物，进而显示出对应的状态标识。
状态显示区中可以用于显示当前冰箱/环境的各种参数，例如冰箱1各间室的温度、湿度、各功能模块(加湿模块、制冰模块、除氧模块、杀菌模块等)的运行状态、环境温度、湿度、日期、时间等。由于控制器340与冰箱1的主控板60电连接，因此这些参数均可从冰箱1的主控板60获取到，进而通过控制器340的转化显示在状态显示区。
例如，状态显示区设置有专门显示冰箱1各间室的温度显示区域，并且以阿拉伯数字作为状态标识进行表征。再例如，当需要显示出8℃时，在温度显示区域内，供电板330给形成数字“8”轮廓的液晶聚合物实施断电，其余区域的液晶聚合物实施通电，这样液晶聚合物就形成了非透明状态的数字“8”。
进一步地，液晶层322具有图案显示区，供电板330配置成控制图案显示区内的液晶聚合物以无序状态呈现出图案标识。图案显示区的显示原理与上述状态显示区相似，图案显示区可以用于显示设计的美术图案、冰箱的卖点、企业商标等。
参见图4，在一些实施例中，该玻璃面板30还可包括通讯模块40。通讯模块40与控制器340、移动终端50相连接，以接收用户通过移动终端50发出的对供电板330的通断指令。
移动终端50可以为手机、电脑、平板电脑、穿戴设备等。通讯模块40可以为Wi-Fi模块、蓝牙模块等。
用户可以通过上述通讯模块40建立移动终端50与控制器340之间的通讯连接，利用移动终端50可远程向控制器340发送对供电板330的通断指令，进而控制液晶视膜320的状态。并且控制器340还可获取到供电板330的实时状态，并通过通讯模块40反馈给移动终端50，用户可以通过移动终端50查看液晶视膜320当前的状态。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
