Description

冰箱及其玻璃门 技术领域
本发明涉及冷藏冷冻技术领域，特别涉及一种冰箱及其玻璃门。
背景技术
传统的冰箱的门体通常包括外侧的门壳和内侧的门衬，门壳与门衬之间通常还设置有较厚的发泡层，门衬上还设置有瓶座等搁物装置。这种门体厚度非常厚，且非常沉重，用户开关门比较费力。
随着技术的进步，冰箱领域出现了一些复合门结构。使冰箱的门体内部开设一个用于储物间室，门体前侧另设一个副门来开闭该门体间室。对于这种复合门技术的冰箱而言，由于设置了双层门体，且门体上存放了更多的存储物，使得门体厚度更厚，重量更重，不仅用户开关门体验不佳，而且门体太厚也严重影响到冰箱外观的美观性。
发明内容
本发明的目的在于至少解决现有技术存在的上述缺陷之一，提供一种更加轻便，外观更加美观的用于冰箱的玻璃门。
本发明的另一目的是要提供一种应用了该玻璃门的冰箱。
本发明的进一步的目的是要使具有复合门结构的冰箱的整体厚度更薄。
一方面，本发明提供了一种用于冰箱的玻璃门，其包括：
玻璃板体；和
外框，其用于铰接于冰箱的箱体或门体，外框沿玻璃板体的边缘延伸，并与玻璃板体的边缘固定连接；且
外框覆盖玻璃板体的部分边缘。
可选地，外框包括竖边框和从竖边框的长度方向两端弯折延伸出的两个横边框，以覆盖玻璃板体的一个竖边和与该竖边相接的两个横边的部分区段。
可选地，玻璃板体的一个横边未被横边框覆盖的区段具有沿竖向方向凸出的把手部。
可选地，每个横边框的长度与玻璃门体的横边长度之比在2/5至3/5之间。
可选地，外框形成有开口朝向玻璃板体边缘的夹槽，以夹持固定玻璃板体的边缘。
可选地，玻璃板体由真空玻璃制成。
另一方面，本发明还提供了一种冰箱，其包括如以上任一项的玻璃门。
可选地，冰箱包括箱体，其前侧敞开以限定出第一间室；门体，安装于箱体，以用于开闭第一间室，门体限定出前侧敞开的第二间室；且玻璃门安装于门体，以用于开闭第二间室。
可选地，门体的后壁开设送风口和回风口，两者均连通第一间室和第二间室；后壁为中空状，其内部限定有连通第一间室的除露风道，后壁前表面向后开设有多个连通第二间室和除露风道的除露孔；冰箱配置成：可处于使第一间室空气经送风口进入第二间室，再经回风口返回第一间室的供冷循环模式；或处于使第一间室空气进入除露风道，以使部分气流经除露孔流至后壁前表面处，以除去其表面凝露的除露模式。
可选地，在从送风口至回风口的方向上，除露孔的排列密度逐渐减小。
本发明的用于冰箱的玻璃门包括固定连接的玻璃板体和外框，由外框与冰箱的其他部件(如箱体或门体)相铰接。玻璃门相对于传统门体的厚度更薄，外观更加美观。并且，本发明并非使外框为一个完整方框，而是使其为半框结构，使其仅覆盖玻璃板体的部分边缘。在保证连接强度的基础上，使外框的总长度更小，使其重量更轻，成本更低，外观更加独特。此外，本发明使玻璃板体由真空玻璃制成，使得其隔热保温性能更好。
进一步地，本发明的玻璃门特别适用于复合门冰箱，门体设置有第二间室，由玻璃门开闭第二间室。由于玻璃门更加轻薄，使得开闭第二间室更加省力。而且，这种结构也使复合门冰箱的门体整体(包括门体和玻璃门)的总厚度不至于过厚，重量不至于过重，使门体整体的开闭更加省力。此外，由于采用玻璃门的外框为半框结构，使得用户视野更加开阔，能够观察到第二间室内的更多细节，提升了产品的档次。
进一步地，本发明通过对门体进行特别设计，能有效去除第二间室的内壁的凝露。具体地，本发明特别使门体后壁为中空状，限定出除霜风道，并使后壁前表面向后开设有多个除露孔。第二空间需要正常制冷时，冰箱运行供冷循环模式，使第一间室空气正常经送风口进入第二间室，对第二间室进行制冷。当第二间室后壁面(也就是门体后壁的前表面)产生凝露需要除露 时，冰箱运行除露模式，使第一间室空气进入门体后壁内部的除露风道，以使部分气流经除露孔流至后壁前表面处。除露风道的空气的相对湿度必然低于门体后壁前表面处的原有气流(凝露附近空气相对湿度必然很高)，故引入除露风道的低湿度空气能够促进凝露的蒸发。
并且，本发明的冰箱在运行除露模式时，并未采用对后壁进行电加热或者引入热空气等传统方式，而是利用第一间室的冷风进行除露，除露进程基本不会对第二间室的正常制冷产生影响，结构设计非常巧妙。
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
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是本发明一个实施例的用于冰箱的玻璃门的结构示意图；
图2是图1所示玻璃门的分解示意图；
图3是本发明一个实施例的冰箱中门体与玻璃门的装配结构示意图；
图4是本发明一个实施例的冰箱处于供冷循环模式的示意图；
图5是图4的A处放大图；
图6是图4所示冰箱在处于除露模式时的状态示意图；
图7是图6的B处放大图。
具体实施方式
下面参照图1至图7来描述本发明实施例的用于冰箱及其玻璃门。其中，“前”、“后”、“上”、“下”、“顶”、“底”、“内”、“外”、“横向”等指示的方位或位置关系为基于附图所示的方位或位置关系，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。
本发明实施例提供了一种用于冰箱的玻璃门，其安装于冰箱的箱体或者门体，以用于开闭对应的储物间室。
图1是本发明一个实施例的用于冰箱的玻璃门的结构示意图；图2是图1所示玻璃门的分解示意图。如图1和图2所示，本发明实施例的用于冰箱 的玻璃门300一般性地可包括玻璃板体310和外框320。玻璃板体310为平板状，其构成玻璃门300的主体部分。玻璃板体310可由真空玻璃制成，以提升其隔热保温性能。
外框320用于铰接于冰箱的箱体或门体。例如图1所示，外框320上下两端均设置铰接轴323，以实现与箱体或门体的铰接。外框320沿玻璃板体310的边缘延伸，并与玻璃板体310的边缘固定连接。也就是说，外框320仅仅覆盖玻璃板体310的边缘部分，以使玻璃板体310的主要部分不被遮挡，发挥其透明的优点。外框320覆盖玻璃板体310的部分边缘。即，玻璃板体310的剩余部分边缘是裸露在外的。
本发明实施例中，玻璃门300相对于传统门体的厚度更薄，外观更加美观。并且，本发明实施例并非使外框320为一个完整的方框，而是使其为半框结构，使其仅覆盖玻璃板体310的部分边缘。在保证连接强度的基础上，使外框320的总长度更短，使其重量更轻，成本更低，外观更加独特。现有一些家具或其他产品的玻璃门体通常采用全封闭外框结构，使得玻璃的全部边缘均被覆盖，缺乏创新。而本发明实施例则突破了这一设计习惯的束缚，创造了全新的玻璃门设计理念。
在一些实施例中，如图1和图2所示，使外框320包括竖边框321和从竖边框321的长度方向两端弯折延伸出的两个横边框322(外框320整体为开口朝向玻璃门300敞开侧的“U”形)，以覆盖玻璃板体310的一个竖边和与该竖边相接的两个横边的部分区段。外框320的这种形状，既有利于布置铰接结构，又能满足外框320的强度要求，结构还最为简洁，重量最为轻便，节约更多材料成本。
进一步地，可使每个横边框322的长度与玻璃门300体的横边长度之比在2/5至3/5之间，以实现强度和轻便的最佳契合。
在一些实施例中，如图1和图2所示，可使外框320形成有开口朝向玻璃板体310边缘的夹槽328，以夹持固定玻璃板体310的边缘，以实现外框320与玻璃板体310的固定连接。这种固定方式结构简单，且连接非常牢固。当然，在一些替代性实施例中，也可采用其他方式完成二者的连接，例如通过粘接的方式。
在一些实施例，如图1和图2所示，可使玻璃板体310的一个横边未被横边框322覆盖的区段具有沿竖向方向凸出的把手部311。例如，使玻璃板 体310的下边缘右侧区段形成一个向下凸出的把手部311(图1的虚线框示意的部位即为把手部311)。本实施例利用玻璃板体310自身的形状形成把手部311，而无需在玻璃表面另外设置塑料或其他材料的把手，使得玻璃板体310的整体结构更加简洁。
本发明实施例还提供了一种冰箱，其包括以上任一实施例的玻璃门300。本发明实施例对冰箱的结构不做额外限定。冰箱可通过蒸气压缩制冷循环系统、半导体制冷系统或其他方式进行制冷。根据制冷温度的不同，冰箱内部的各间室可划分为冷藏室、冷冻室和变温室。例如冷藏室内的温度一般控制在2℃至10℃之间，优先为4℃至7℃。冷冻室内的温度范围一般控制在-22℃至-14℃。变温室可在-18℃至8℃之间调节，以实现变温效果。不同种类的物品的最佳存储温度并不相同，适宜存放的储物间室也并不相同。例如果蔬类食物适宜存放于冷藏室，而肉类食物适宜存放于冷冻室。
本发明的玻璃门300特别适用于复合门冰箱。图3是本发明一个实施例的冰箱中门体与玻璃门300的装配结构示意图；图4是本发明一个实施例的冰箱处于供冷循环模式的示意图。
如图3和图4所示，冰箱为复合门冰箱，具体地，冰箱包括箱体100、门体200和玻璃门300。箱体100的前侧敞开以限定出第一间室101。门体200安装于箱体100，以用于开闭第一间室101，门体200限定出前侧敞开的第二间室201。玻璃门300安装于门体200，以用于开闭第二间室201。本发明实施例的第一间室101优选为冷藏室。门体200的前侧可设置有密封条400，以用于与玻璃门300的后表面实现密封。门体200前侧还可设置有磁铁500，以用于吸引玻璃门300上的另一磁铁，使玻璃门300关闭地更严密，减少冷气泄漏。
可使门体200在箱体100前侧可转动地安装于箱体100，门体200前侧敞开以限定出前述的第二间室201，使玻璃门300在门体200前侧可转动地安装于门体200。门体200打开时，用户从第一间室101存取物品。门体200关闭，玻璃门300打开时，用户可从第二间室201存取物品。
本发明实施例由玻璃门300开闭第二间室201。由于玻璃门300更加轻薄，用户开闭第二间室201更加省力。而且也使复合门冰箱的门体整体(包括门体200和玻璃门300)的总厚度不至于过厚，重量不至于过重，使门体整体的开闭更加省力。此外，由于采用玻璃门300的外框320为半框结构， 使得用户视野更加开阔，能够观察到第二间室201内的更多细节，提升了产品的档次。
图5是图4的A处放大图；图6是图4所示冰箱在处于除露模式时的状态示意图；图7是图6的B处放大图，各图中用箭头示意了风向。
现有的复合门冰箱常常出现门体间室(本发明为第二间室201)内壁凝露问题。发明人认识到，由于门体200的后壁211临近第一间室101，与第一间室101内的空气可通过热传导进行传热，故该后壁211前表面的温度相比第二间室201的其他壁面的温度要更低，更容易产生凝露。
基于上述认识，本发明实施例通过对门体200进行特别设计，针对性地对第二间室201的后壁211的前表面进行除露。具体地，门体200的后壁211开设送风口212和回风口214，两者均连通第一间室101和第二间室201。并且，门体200的后壁211为中空状，其内部限定有连通第一间室101的除露风道215。即，后壁211的中空空间构成除露风道215。后壁211的前表面向后开设有多个连通第二间室201和除露风道215的除露孔2154。冰箱配置成：可处于使第一间室101空气经送风口212进入第二间室201，再经回风口214返回第一间室101的供冷循环模式，以利用第一间室101的冷气对第二间室201进行制冷，如图4和图5。或者，冰箱处于使第一间室101空气进入除露风道215，以使部分气流经除露孔2154流至后壁211前表面处，以除去其表面凝露的除露模式，如图6和图7。
本发明实施例中，冰箱在通常状态下处于前述的供冷循环模式。但是当因为开关门操作引入湿空气或者放入高湿存储物后，门体200的后壁211前表面出现较多凝露时候，可控制冰箱运行前述的除露模式，使第一间室101空气进入门体200的后壁211内部的除露风道215，以使部分气流经除露孔2154流至后壁211前表面处。由于除露风道215的空气的相对湿度必然低于门体200后壁211前表面处的原有气流的相对湿度(凝露附近空气相对湿度必然很高)，故引入除露风道215的低湿度空气能够促进凝露的蒸发，完成除露过程。当完成除露后，可控制冰箱切换至供冷循环模式。
供冷循环模式和除露模式的切换时机可由冰箱自动控制，例如定时切换或者根据湿度传感器的检测结果自动切换冰箱运行模式。也可人工控制，例如用户发现需要除露或者需要停止除露时可手动切换冰箱运行模式。
本发明实施例的冰箱在运行除露模式时，也并未采用对后壁211进行电 加热或者引入热空气等传统方式，依然是利用第一间室101的冷风进行除露，除露进程基本不会对第二间室201的正常制冷产生影响，结构设计非常巧妙。
在一些实施例中，如图4和图6所示，可使除露风道215具有连通第一间室101的进口2151和出口2152，以便在除露风道215和第一间室101之间形成风路循环，避免用于除露的气流淤积在除露风道215和除露孔2154附近无法流通，而影响除露效果。此外，冰箱还配置成在处于供冷循环模式时，使进口2151和出口2152分别处于关闭状态和打开状态；在处于除露模式时，使进口2151和出口2152均处于打开状态。也就是说，在供冷循环模式时，仅需关闭除露风道215的进口2151。在处于除露模式时，打开除露风道215的进口2151。由于已经通过控制除露风道215的进口2151和出口2152的开闭来控制除露风道215的导通和封闭，故无需对除露风道215的出口2152进行控制。在两种模式下，除露风道215的出口2152处于常开状态，不需进行控制，以简化冰箱结构和控制。
在一些实施例中，如图4和图6所示，可使除露风道215的进口2151穿透送风口212的侧壁以连通送风口212。即，除露风道215借用送风口212与第一间室101实现连通，无需再在后壁211另外开口。也可使除露风道215的出口2152穿透回风口214的侧壁以连通回风口214。即，除露风道215借用回风口214与第一间室101实现连通，无需再在后壁211另外开口。这种设计结构非常巧妙，简化了门体200后壁211的开孔结构，使门体200后壁211后表面仅需直接开设送风口212和回风口214即可。
在一些实施例中，如图4和图6所示，使送风口212和回风口214分别位于后壁211的顶部和底部。冰箱处于供冷循环模式时，冷空气从送风口212流入第二间室201后，因密度相对较大具有下沉作用，将向下流动并依次对第二间室201各高度区域进行制冷，空气温度逐渐升高后再从第二间室201底部的回风口214流回第一间室101。这样形成了更加通畅的风路循环，提升了第二间室201的制冷效果。在冰箱处于除露模式时，冷空气从除露风道215的顶部进入除露风道215，也更利于向下流动，使除露风道215流通性更好，利于加快除露进程。
如图5和图7所示，冰箱还可包括风门216，风门216安装于送风口212处，并配置成可受控地运动至关闭进口2151且导通送风口212的供冷状态(如图5)，或运动至打开进口2151且关闭送风口212的除露状态(如图7)。 本实施例有效利用了进口2151与送风口212相连通的优势，利用一个风门216同时控制送风口212和进口2151，简化了进出风控制，设计非常巧妙。
具体地，如图5和图7所示，可使风门216的一端可转动地安装于进口2151前边缘处，以便转动至供冷状态(如图5)或除露状态(如图7)。本发明实施例中，无需设置复杂的运动机构和控制逻辑，仅控制一个风门216的转动，就能完成冰箱运行模式的切换，结构和控制都极大简化。
在一些实施例中，如图4至图7所示，冰箱还包括风机230，风机230位于送风口212处，以用于促使第一间室101的空气流向送风口212，以加快供冷循环速度。当然，对于进口2151与送风口212连通的方案而言，风机230还用于促使第一间室101的空气流向除露风道215。
发明人认识到，越接近送风口212，门体200的后壁211产生的凝露越多，越接近回风口214，凝露越少。为此，本发明实施例特别对除露孔2154的排列密度进行设计，在从送风口212至回风口214的方向上，使除露孔2154的排列密度逐渐减小，以匹配门体200后壁211不同位置凝露程度的变化趋势，减少过多无意义的开孔。可使门体200后壁211的开孔区域遍布整个后壁211前表面，以实现充分除露，也可使其遍布后壁211前表面的一部分区域。除露孔2154的开孔率可为30％～80％。除露孔2154可为矩阵式排布或其他排布。除露孔2154可为圆形、椭圆形、方形或其他形状。优选地，使除露孔2154为长度方向平行于除露风道215气流方向的长条状孔，这种结构利于破坏露珠的完整性，加快露珠的分散和蒸发。
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。
