Description

冷藏冷冻装置
本申请要求了申请日为2016年12月09日，申请号为201611132067.6，发明名称为“冷藏冷冻装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及冰箱储物技术领域，特别是涉及一种冷藏冷冻装置。
背景技术
冰箱是保持恒定低温的一种制冷设备，也是一种使食物或其他物品保持恒定低温冷态的民用产品。随着生活品质的提高，消费者对储存食品的保鲜的要求也越来越高，特别是对食物的色泽、口感等的要求也越来越高。因此，储存的食物也应当保证在储存期间，食物的色泽、口感、新鲜程度等尽可能的保持不变。目前市场上为了更好的储存食物，仅有真空保鲜一种。经常采用的真空保鲜方式为真空袋保鲜和真空储物间室保鲜。
采用真空袋保鲜，消费者每次存储食物都需要进行抽真空动作，操作麻烦，得不到消费者的喜爱。
采用真空储物间室保鲜，由于箱体等为刚性结构，要保持真空状态，对抽真空系统的要求很高，对冰箱的密封性能要求很高，每取放一件物品，涌进的新空气多，对能量的消耗较大。而且，真空环境下，食物接收冷量比较困难，特别不利于食物的储存。此外，由于为真空环境，用户每次打开冰箱门等需要费很大的力气，造成用户使用不便。虽然有的冰箱可通过抽真空系统向真空储物间室内通气，然而这样会造成用户等待较长时间，时效性差。真空时间较长，也会造成冰箱箱体等变形严重，即现有的具有抽真空结构的冰箱不能很好地完成真空保鲜，需要箱体等的强度很大，实现要求很高，成本很高。
此外，发明人发现：由于传统上用于气调保鲜的制氮设备体积庞大、成本高昂，导致该技术基本上还是局限于使用在各种大型的专业贮藏库上(储藏容量一般至少30吨以上)。可以说，采用何种适当的气体调节技术和相应装置才可能经济地将气调系统小型化、静音化，使其适用于家庭或个人用户，是气调保鲜领域技术人员一直渴望解决但始终未能成功解决的技术难题。
发明内容
本发明旨在克服现有冰箱的至少一个缺陷，提供一种冷藏冷冻装置，其创造性地提出了 将气调保鲜空间内空气中的氧气排出该空间，从而在该空间内获得富氮贫氧以利于食物保鲜的气体氛围，该气体氛围通过降低果蔬保存空间内氧气的含量，降低果蔬有氧呼吸的强度，同时保证基础的呼吸作用，防止果蔬进行无氧呼吸，从而达到果蔬长期保鲜的目的。
为此，本发明提供了一种冷藏冷冻装置，其包括：
箱体，箱体具有内胆、设置于内胆外侧的壳体，以及位于内胆和壳体之间的保温层；内胆内限定有储物空间，储物空间内设置有储物容器，储物容器内具有气调保鲜空间；
气调膜组件，气调膜组件具有至少一个气调膜和一富氧气体收集腔，且其周围空间与气调保鲜空间连通，气调膜组件配置成使得气调膜组件周围空间气流中的氧气相对于气调膜组件周围空间气流中的氮气更多地透过气调膜进入富氧气体收集腔；和
抽气泵，抽气泵设置于内胆和壳体之间的保温层中，抽气泵的进口端经由管路与气调膜组件的富氧气体收集腔连通，以将透入富氧气体收集腔内的气体抽排到储物容器外。
可选地，储物容器为抽屉组件，包括：

抽屉本体，可滑动地安装于抽屉筒体内，以从抽屉筒体的前向开口可操作地向外抽出和向内插入抽屉筒体。
可选地，壳体包括背板，抽气泵设置于内胆的后壁与背板之间，且处于储物容器的后方。
可选地，冷藏冷冻装置还包括：密封盒，安装于内胆和壳体之间；安装框架，经由多个减震垫块安装于密封盒内；抽气泵安装于安装框架。
可选地，抽屉筒体的顶壁内设置有与气调保鲜空间连通的容纳腔，以容置气调膜组件。
可选地，在抽屉筒体的顶壁的容纳腔与气调保鲜空间之间的壁面中开设有至少一个第一通气孔和与至少一个第一通气孔间隔开的至少一个第二通气孔，以分别在不同位置连通容纳腔与气调保鲜空间；冷藏冷冻装置还包括风机，设置在容纳腔内，以促使气调保鲜空间的气体依次经由至少一个第一通气孔、容纳腔和至少一个第二通气孔返回气调保鲜空间。
可选地，风机为离心风机，设置于至少一个第一通气孔的上方且使得离心风机的旋转轴线竖直向下，进风口朝向至少一个第一通气孔；气调膜组件设置于至少一个第二通气孔的上方且使得气调膜组件的每个富氧膜平行于顶壁。
可选地，离心风机设置于容纳腔的前部；气调膜组件设置有离心风机的后方。
可选地，气调膜组件还包括支撑框架，其具有相互平行的第一表面和第二表面，且支撑框架上形成有分别在第一表面上延伸、在第二表面上延伸，以及贯穿支撑框架以连通第一表面与第二表面的多个气流通道，多个气流通道共同形成富氧气体收集腔；至少一个气调膜为 两个平面形气调膜，分别铺设在支撑框架的第一表面和第二表面上。
可选地，储物空间为冷藏空间；箱体还限定出冷冻空间和变温空间，冷冻空间设置于储物空间的下方，变温空间设置于冷冻空间和冷藏空间之间。
本发明的冷藏冷冻装置因为具有气调膜组件和抽气泵，可使气调保鲜空间内形成富氮贫氧以利于食物保鲜的气体氛围，该气体氛围通过降低果蔬保存空间内氧气的含量，降低果蔬有氧呼吸的强度，同时保证基础的呼吸作用，防止果蔬进行无氧呼吸，从而达到果蔬长期保鲜的目的。
进一步地，由于本发明的冷藏冷冻装置中抽气泵设置于内胆和壳体之间的保温层中，可显著降低抽气泵运行时候的噪音，给用户更好的静音体验。尤其是抽气泵处于储物容器的后方，气调膜组件处于容纳腔的后部，还可缩短管路的长度，可以减小气调的真空度损失。
进一步地，本发明的冷藏冷冻装置不仅保鲜效果好，而且对储物容器等的刚性、强度要求较低，实现要求很低，则成本也很低。而且，本发明的冷藏冷冻装置很好地解决了气调保鲜领域技术人员一直渴望解决但始终未能成功解决的上述技术难题。本发明的冷藏冷冻装置不仅体积小，而且噪音也很低，特别适用于家庭和个人使用。
进一步地，本发明的冷藏冷冻装置优选为冰箱，例如，家用压缩式直冷冰箱，家用压缩式风冷冰箱，当然，也可为半导体制冷冰箱。

具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
图1是根据本发明一个实施例的冷藏冷冻装置的示意性局部结构图；图2是图1所示结构的另一视角的示意性局部结构图。如图1和图2所示，本发明实施例提供了一种冷藏冷冻装置，其可包括箱体20、主门体、气调膜组件30、抽气泵41和制冷系统。
箱体20可包括内胆21、设置于内胆21外侧的壳体27，以及位于内胆21和壳体27之间的保温层。内胆21内限定出储物空间211。主门体可由两个对开门体组成，两个对开门体均可转动安装于箱体20，配置成打开或关闭箱体20限定的储物空间211。主门体也可为一个门体。进一步地，储物空间211内设置有储物容器，储物容器内具有气调保鲜空间。气调保鲜空间可为密闭型空间或近似密闭型空间。优选地，储物容器为抽屉组件。储物容器可包括抽屉筒体22和抽屉本体23。抽屉筒体22可具有前向开口，且设置于储物空间211内，具体可设置于储物空间211的下部。如本领域技术人员可认识到的，抽屉筒体22也可设置于储物空间211的中部或上部。抽屉本体23可滑动地设置于抽屉筒体22内，以从抽屉筒体22的前向开口可操作地向外抽出和向内插入抽屉筒体22。抽屉本体23可具有抽屉端盖，抽屉端盖可与抽屉筒体22的开口相配合，以进行气调保鲜空间的密闭。在一些替代性实施实施例中，储物容器可包括筒体和配置成打开或关闭筒体的小门体。
制冷系统配置成向储物空间21提供冷量。具体地，在一些实施方式中，制冷系统可为由压缩机、冷凝器、节流装置和蒸发器等构成的制冷循环系统。蒸发器配置成直接或间接地向储物空间211内提供冷量。例如当该冷藏冷冻装置为家用压缩式直冷冰箱时，蒸发器可设置于内胆21的后壁面外侧或内侧。当该冷藏冷冻装置为家用压缩式风冷冰箱时，箱体20内还具有蒸发器室，蒸发器室通过风路系统与储物空间211连通，且蒸发器室内设置蒸发器，出口处设置有风机，以向储物空间211进行循环制冷。在另一些实施方式中，制冷系统也可为半导体制冷装置。
气调膜组件30具有至少一个气调膜31和一富氧气体收集腔，且其周围空间与气调保鲜空间连通。该气调膜组件30可配置成使得气调膜组件30周围空间气流中的氧气相对于气调膜组件30周围空间气流中的氮气更多地透过气调膜31进入富氧气体收集腔。具体地，每个气调膜31的内侧表面朝向富氧气体收集腔，以在富氧气体收集腔的压力小于气调膜组件30的周围空间的压力时，使气调膜组件30的外部空间的空气中的氧气相对于其中的氮气更多地透过至少一个气调膜31进入富氧气体收集腔。
抽气泵41可设置于内胆21和壳体27之间的保温层中，抽气泵41的进口端经由管路与气调膜组件30的富氧气体收集腔连通，以将透入富氧气体收集腔内的气体抽排到储物容器外。抽气泵41的出口连接的排气管路可穿过保温层伸入蒸发皿内，蒸发皿也可被称为接水盘。
在该实施例中，抽气泵41向外抽气，可使富氧气体收集腔的压力小于气调膜组件30的周围空间的压力，进一步地，可使气调膜组件30周围空间内的氧气进入富氧气体收集腔。 由于气调保鲜空间与气调膜组件30周围空间连通，气调保鲜空间内的空气会进入气调膜组件30周围空间，因此也可使气调保鲜空间内的空气中的氧气进入富氧气体收集腔，从而在气调保鲜空间内获得富氮贫氧以利于食物保鲜的气体氛围。
本发明的冷藏冷冻装置可使气调保鲜空间内形成富氮贫氧以利于食物保鲜的气体氛围，该气体氛围通过降低果蔬保存空间内氧气的含量，降低果蔬有氧呼吸的强度，同时保证基础的呼吸作用，防止果蔬进行无氧呼吸，从而达到果蔬长期保鲜的目的。而且，该气体氛围还具有大量的氮气等气体，还不会降低气调保鲜空间内物品的受冷效率，可使果蔬等有效得到储存。而且对箱体20等的刚性、强度要求较低，实现要求很低，则成本也很低。本发明的冷藏冷冻装置很好地解决了气调保鲜领域技术人员一直渴望解决但始终未能成功解决的上述技术难题。本发明的冷藏冷冻装置不仅体积小，而且噪音也很低，特别适用于家庭和个人使用。抽气泵41设置于保温层中可显著降低抽气泵运行时候的噪音，给用户更好的静音体验。
在本发明的一些实施例中，抽屉筒体22上可开设有多个微孔，储物空间211和气调保鲜空间经由多个微孔连通。微孔也可被称为气压平衡孔，每个微孔可为毫米级的微孔，例如每个微孔的直径为0.1mm至3mm，优选为1mm、1.5mm等。设置多个微孔可使气调保鲜空间内的压力不至于太低，多个微孔的设置也不会使气调保鲜空间内的氮气向大的储物空间211流动，即使流动也是很小甚至是可忽略不计的，不会影响气调保鲜空间内食物的保存。在本发明的一些可选实施例中，抽屉筒体22上也可不设置微孔，即使这样，气调保鲜空间内还具有大量的氮气等气体存在，用户在拉开抽屉本体23时，也不用太费力气，相比于现有的真空储物室，则会大大省力。
在本发明的一些实施例中，内胆21可为冷藏室内胆，储物空间211为冷藏空间，其储藏温度一般在2℃至10℃之间，优先为3℃至8℃。进一步地，箱体20还可限定出冷冻空间25和变温空间26，即箱体20还可包括冷冻室内胆，变温室内胆。冷冻空间25设置于储物空间211的下方，变温空间26设置于冷冻空间和冷藏空间之间。冷冻空间内的温度范围一般在-14℃至-22℃。变温空间可根据需求进行调整，以储存合适的食物。在本发明的一些替代性实施例中，储物空间211也可为冷冻空间或变温空间，也就是说，储物空间211的温度范围可控制在-14℃至-22℃或根据需求进行调整。进一步地，冷藏空间、冷冻空间和变温空间的相对位置可根据实际需求进行调整。
在本发明的一些实施例中，壳体27可包括背板，抽气泵41设置于内胆21的后壁与背板之间，且处于储物容器的后方，以缩短抽气泵41与气调膜组件30间管路的长度，可以减 小气调的真空度损失。
图3是根据本发明一个实施例的冷藏冷冻装置中抽气泵组件40的示意性分解图。进一步地为了降低噪音，如图3所示，在本发明的一些实施例中，冷藏冷冻装置还可包括密封盒43和安装框架44。安装框架44与密封盒43的内壁可通过多个减振垫块连接，抽气泵41固定于安装框架44内部，如此以减轻抽气泵41运行时的振动和噪音。具体地，安装框架44的底部设置有两个减振垫块45，减振垫块45套设在密封盒43底面的定位柱46上。安装框架44的一个相对两侧各设置有一个圆形的减振垫块47，且卡设于密封盒43相应卡槽48内。安装框架44的另外一相对两侧各固定一个减振垫块49。抽气泵41可处于密封盒43内的各个减振垫块之间，且通过螺钉紧固于安装框架。进一步地，保温层中还设置有由隔板以及内胆21的后壁等隔开的泵组件安装腔，密封盒43可设置于泵组件安装腔。密封盒43可听过减震组件安装于泵组件安装腔内。
在本发明的一些实施例中，如图4和图5所示，气调膜组件30可设置于抽屉筒体22的筒体壁上。气调膜组件30可呈平板型，且可优选地且水平地设置于抽屉筒体22的顶壁。具体地，抽屉筒体22的顶壁内设置有容纳腔221，以容置气调膜组件30。例如，在抽屉筒体22的顶壁的容纳腔与气调保鲜空间之间的壁面中开设有至少一个第一通气孔222和第二通气孔223。至少一个第一通气孔222与至少一个第二通气孔223间隔开，以分别在不同位置连通容纳腔与气调保鲜空间。第一通气孔222和第二通气孔223均为小孔，且数量均可为多个。在一些替代性实施例中，抽屉筒体22的顶壁内侧具有凹陷槽。气调膜组件30设置于抽屉筒体22的顶壁的凹陷槽内。
在本发明的一些实施例中，为了促使气调保鲜空间与容纳腔221内的气体流动，冷藏冷冻装置还可包括风机60，风机60可设置于容纳腔内，配置成促使气调保鲜空间的气体经由第一通气孔222进入容纳腔221，且使容纳腔221内的气体经由第二通气孔223进入气调保鲜空间。也就是说，风机60可促使气调保鲜空间的气体依次经由至少一个第一通气孔222、容纳腔和至少一个第二通气孔223返回气调保鲜空间。
风机60优选为离心风机，设置于容纳腔221内第一通气孔222处。也就是说，离心风机位于至少一个第一通气孔222的上方，且旋转轴线竖直向下，进风口正对于第一通气孔222。离心风机的出气口可朝向气调膜组件30。气调膜组件30设置于至少一个第二通气孔223的上方且使得气调膜组件30的每个气调膜平行于抽屉筒体22的顶壁。至少一个第一通气孔222设置于顶壁前部，至少一个第二通气孔223设置于顶壁后部。即，离心风机设置于容纳腔221的前部，气调膜组件30设置于容纳腔221的后部，气调膜组件30设置于离心风 机的后方。进一步地，抽屉筒体22的顶壁包括主板部224和盖板部225，主板部224的一局部区域中形成有凹陷部，盖板部225可拆卸地盖设于凹陷部上，以形成容纳腔221。为了便于抽屉筒体22的制作，主板部224可与抽屉筒体22的侧壁、底壁、后壁一体成型。
在本发明的一些实施例中，如图6所示，气调膜组件30可呈平板型，该气调膜组件30还可包括支撑框架32。气调膜31优选为富氧膜，可为两个，安装于支撑框架32的两侧，以使两个气调膜31和支撑框架32共同围成富氧气体收集腔。进一步地，支撑框架32可包括边框，设置于边框内的肋板和/或平板等结构，肋板之间、肋板与平板之间等可形成气流通道，肋板的表面上、平板的表面上均可开设有凹槽，以形成气流通道。肋板和/或平板可提高气调膜组件30的结构强度等。也就是说，支撑框架32具有相互平行的第一表面和第二表面，且支撑框架32上形成有分别在第一表面上延伸、在第二表面上延伸，以及贯穿支撑框架32以连通第一表面与第二表面的多个气流通道，多个气流通道共同形成富氧气体收集腔；至少一个气调膜31为两个平面形气调膜，分别铺设在支撑框架32的第一表面和第二表面上。
在本发明的一些实施例中，支撑框架32包括与前述至少一个气流通道连通的抽气孔33，设置于边框上，以允许富氧气体收集腔中的氧气被输出。抽气孔33与抽气泵41连通。抽气孔33可设置于边框的长边缘上，或设置于边框的短边缘上，以根据气调膜组件30的设置方位或实际设计需求进行确定，例如，在图4和图5所示的实施例中，抽气孔33可设置于边框的长边缘上。气调膜31先通过双面胶34安装于边框，然后通过密封胶35进行密封。
在一些实施例中，支撑框架32可包括：边框，多个第一肋板以及多个第二肋板。前述多个第一肋板在边框内部沿纵向间隔设置且沿横向延伸，且前述多个第一肋板的一侧表面形成第一表面。多个第二肋板在前述多个第一肋板的另一侧表面沿横向间隔设置且沿纵向延伸，且前述多个第二肋板的远离第一肋板的一侧表面形成第二表面。本发明的支撑框架32通过在其边框内部设置沿纵向间隔且沿横向延伸的多个第一肋板和在前述多个第一肋板的一侧表面沿横向间隔且沿纵向延伸的多个第二肋板，从而一方面保证了气流通道的连贯性，另一方面大大缩小了支撑框架32的体积，并且极大地增强了支撑框架32的强度。此外，支撑框架32的上述结构保证了气调膜31能够获得足够的支撑，即使在富氧气体收集腔内部负压较大的情况下也能够始终保持较好的平整度，保证了气调膜组件30的使用寿命。
在进一步的实施例中，前述多个第一肋板可包括：多个第一窄肋板和多个第一宽肋板。其中多个第一宽肋板间隔设置，相邻两个第一宽肋板之间设置多个第一窄肋板。前述多个第二肋板可包括：多个第二窄肋板和多个第二宽肋板，多个第二宽肋板间隔设置，相邻两个第 二宽肋板之间设置多个第二窄肋板。本领域技术人员容易理解，此处的“宽”“窄”是相对而言的。
在一些实施例中，每个第一宽肋板自其形成第一表面的一侧表面向内凹陷以形成第一沟槽；每个第二宽肋板自其形成第二表面的一侧表面向内凹陷形成第二沟槽，从而在保证支撑框架32的厚度很小(或者说体积很小)的前提下，提高了其内部网格结构的连通性。
在进一步的实施例中，每个第一宽肋板的背离第一表面的部分表面朝第二肋板延伸至与第二表面平齐，且自与第二表面平齐的该部分表面向内凹陷形成第三沟槽；第三沟槽与第二沟槽交叉的部位连通以形成十字沟槽。前述多个第二宽肋板中至少一个第二宽肋板的背离第二表面的部分表面朝第一肋板延伸至与第一表面平齐，且自与第一表面平齐的该部分表面向内凹陷形成第四沟槽；其中第四沟槽与第一沟槽交叉的部位连通以形成十字沟槽。
在本发明的一些实施例中，在本发明的一些实施例中，为了便于气流的流动，盖板部225的内表面可向下延伸出多个导风肋板，以引导来自风机60的气流在容纳腔内流过气调膜组件30每个气调膜31的背离富氧气体收集腔的外侧表面。多个导风肋板可分成两组，包括第一组导风肋板与第一组导风肋板关于一个平面对称设置的第二组导风肋板。每组导风肋板包括第一导风肋板、至少一个第二导风肋板和至少一个第三导风肋板。第一导风肋板从离心风机的出风口处向容纳腔的一侧延伸，且延伸至气调膜组件30的一个横向外侧。每个第二导风肋板设置于两个第一导风肋板之间，且处于气调膜组件30和离心风机之间。每个第三导风肋板位于气调膜组件30的一个横向外侧，以引导气流使气流从气调膜组件30的横向两侧进入气调膜组件30与容纳腔的底表面或顶表面之间的间隙。
在本发明的一些实施例中，抽屉本体23和抽屉筒体22之间设置有锁定装置、把手和把手定位装置。锁定装置包括设置于抽屉端盖两侧的枢转锁扣、设置于抽屉筒体22上的两个扣合部，以及卡接促使装置。每个扣合部可为凸起。卡接促使装置可用于促使两个枢转锁扣朝卡接于各自相应的扣合部的方向(即各自的第一方向)转动。把手水平延伸，且可沿竖直方向可滑动地安装于抽屉端盖。而且，在抽屉本体23处于关闭状态时，把手所处的位置可为把手的初始位置。且把手配置成在其初始位置时，其两端分别与两个枢转锁扣接触抵靠，以阻止每个枢转锁扣沿与各自相应的第一方向相反的另一方向转动，以使枢转锁扣与扣合部保持配合状态，从而将抽屉本体23锁定于抽屉筒体22。进一步地，当把手向上或向下移动至解除保持锁定位置，即从初始位置移动到解除保持锁定位置后，可允许每个枢转锁扣沿与各自相应的第一方向相反的另一方向转动，以允许在向外拉动抽屉本体23时，枢转锁扣转动脱离相应的扣合部，从而允许打开抽屉本体23。把手定位装置配置成在当把手运动到各 个预定的位置处后，使把手保持处于该位置处，主要是初始位置和解除保持锁定位置。当打开抽屉本体时，用户先使把手向上或下运动到解除保持锁定位置，把手定位装置使把手保持处于该位置，用户可向外拉开抽屉本体23。当关闭抽屉本体时，用户先使抽屉本体23关闭，然后使把手向下或上回到初始位置，把手定位装置使把手保持处于该位置，从而使抽屉本体23和抽屉筒体22保持处于锁定状态。
为了进一步使把手的运动平稳，把手的两端还分别设置有导向杆和滑块，导向杆沿竖直方向延伸。抽屉本体23还包括两组滑道，每组滑道至少有三个沿竖直方向延伸的滑槽，以使导向杆的两侧分别具有一个滑槽，滑块在其余的滑槽上运动，或使滑块的两侧分别具有一个滑槽，导向杆在其余的滑槽上运动。例如，每组滑道可包括四个滑槽，导向杆的前后两侧分别具有一个滑槽，滑块的横向两侧(即左右两侧)分别具有一个滑槽。
上文所列出的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
