Description

冷藏冷冻装置
本申请要求了申请日为2016年12月02日，申请号为201611097472.9，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。
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一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。
特别地，本发明提供的冷藏冷冻装置可防止从空间内排出的气体中冷量传递至壳体等地方，从而可防止在壳体上，尤其是侧壳、背板等地方产生凝露。
为此，本发明提供了一种冷藏冷冻装置，其包括：
箱体，所述箱体内限定有储物空间；所述储物空间内设置有储物容器，所述储物容器内具有气调保鲜空间；
气调膜组件，所述气调膜组件具有至少一个气调膜和一富氧气体收集腔，且其周围空间与所述气调保鲜空间连通，所述气调膜组件配置成使得所述气调膜组件周围空间气流中的氧气相对于所述气调膜组件周围空间气流中的氮气更多地透过所述气调膜进入所述富氧气体收集腔；
氧气排出管路，其进口与所述气调膜组件的所述富氧气体收集腔连通；
抽气装置，设置于所述氧气排出管路上，以将透入所述富氧气体收集腔内的气体抽排到所述储物容器外；和
防凝露装置，配置成至少部分地阻碍所述氧气排出管路的至少部分管段内的冷量向所述至少部分管段外侧传递。
可选地，所述防凝露装置为保温管或保温套，套装于所述氧气排出管路的所述至少部分管段。
可选地，所述箱体包括：
内胆，其内限定出所述储物空间；和
壳体，设置于所述内胆的外侧，其具有背板和两个侧壳；
所述氧气排出管路的所述至少部分管段位于所述内胆外，且临近所述壳体的一个所述侧壳和所述背板。
可选地，所述储物空间为冷藏空间；所述箱体还限定出冷冻空间、变温空间和压缩机仓，所述冷冻空间设置于所述储物空间的下方，所述变温空间设置于所述冷冻空间和所述冷藏空间之间；所述压缩机仓设置于所述冷冻空间的后下方。
可选地，所述抽气装置设置于所述压缩机仓；且
所述氧气排出管路包括竖直管段，设置于所述储物空间的后方；
所述氧气排出管路的所述至少部分管段为所述竖直管段。
可选地，所述储物容器为抽屉组件，包括：
筒体，具有前向开口，且设置于所述储物空间内；和
抽屉，可滑动地设置于所述筒体内，以从所述筒体的前向开口可操作地向外抽出和向内 插入所述筒体。
可选地，所述筒体的顶壁内设置有与所述气调保鲜空间连通的容纳腔，以容置所述气调膜组件。
可选地，在所述筒体的顶壁的所述容纳腔与所述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所述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所述容纳腔与所述气调保鲜空间；
所述冷藏冷冻装置还包括风机，设置在所述容纳腔内，以促使所述气调保鲜空间的气体依次经由所述至少一个第一通气孔、所述容纳腔和所述至少一个第二通气孔返回所述气调保鲜空间。
可选地，所述风机为离心风机，设置于所述至少一个第一通气孔的上方；所述气调膜组件设置于所述至少一个第二通气孔的上方。

本发明的冷藏冷冻装置因为具有气调膜组件和抽气装置，抽气装置可使气调膜一侧的压力小于另一侧，从而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。
特别地，由于本发明的冷藏冷冻装置还包括防凝露装置，可至少保证氧气排出管路中临近壳体设置的至少部分管段内的冷气与外部充分隔绝，从而杜绝侧壳及背板发生凝露。
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体积小、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家用冰箱，例如，家用压缩式直冷冰箱，家用 压缩式风冷冰箱，半导体制冷冰箱等。
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结构图；
图3是根据本发明一个实施例的冷藏冷冻装置中抽气装置的示意性分解图；
图4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6是根据本发明一个实施例的冷藏冷冻装置中气调膜组件的分解图。
具体实施方式
图1是根据本发明一个实施例的冷藏冷冻装置的示意性结构图，图2是图1所示结构的另一视角的示意性结构图。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、制冷系统、气调膜组件30、抽气装置40和氧气排出管路50。
箱体20内限定有储物空间211。例如，箱体20可包括内胆21，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，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。储物容器可包括筒体22和抽屉23。筒体22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，筒体22也可设置于储物空间211的中部或上部。抽屉23可滑动地安装于筒体22，以从筒体22的前向开口可操作地向外抽出和向内插入筒体22。抽屉23可具有抽屉端盖，抽屉端盖可与筒体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。
制冷系统可为压缩式制冷系统，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。在一些替代性实施方案中，制冷系统也可为其它类型的制冷装置，如半导体制冷装置。
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。
氧气排出管路50的进口可与气调膜组件30的富氧气体收集腔连通，以用于排出气调保鲜空间内的氧气。抽气装置40设置于氧气排出管路50上，以将透入富氧气体收集腔内的气体抽排到储物容器外。
在该实施例中，抽气装置受控地向外抽气，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。
特别地，在本发明的该实施例中，冷藏冷冻装置还可包括防凝露装置70，配置成至少部分地阻碍氧气排出管路50的至少部分管段内的冷量向至少部分管段外侧传递，以防止冷 量传递至临近氧气排出管路50的至少部分管段的部件，从而在这些部件上产生凝露等现象。例如，箱体20还包括壳体27。壳体27设置于内胆21的外侧，其具有背板和两个侧壳。由于空间位置限制，氧气排出管路50的至少部分管段位于内胆21外，且临近壳体21的一个侧壳和背板，距离侧壳及背板较近，设置防凝露装置70可防止该侧壳和背板上产生凝露，可防止对冷藏冷冻装置的感官性能造成影响。
在本发明的一些实施例中，防凝露装置70为保温管或保温套，套装于氧气排出管路50的至少部分管段。保温管优选为橡胶保温管，可保证氧气排出管路内冷气与外部充分隔绝，从而杜绝壳体发生凝露。进一步地，抽气装置40可处于氧气排出管路50的出口端或中部。在本发明的一些替代性实施例中，防凝露装置70也可为电加热网，套装于氧气排出管路50。
在本发明的一些实施例中，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还可限定出压缩机仓24、冷冻空间25和变温空间26，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25和冷藏空间之间。冷冻空间25内的温度范围一般在-14℃至-22℃。变温空间26可根据需求进行调整，以储存合适的食物。压缩机仓24优选地设置于冷冻空间25的后下方。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。
抽气装置40优先设置于压缩机仓24；且氧气排出管路50包括竖直管段，设置于储物空间211的后方。氧气排出管路的至少部分管段为竖直管段。竖直管段可从压缩机仓24的上板延伸至储物空间211的后方，也就是说，橡胶保温管的上端位于储物空间211的后方，下端位于接压缩机仓24的上板，与氧气排出管路50的连接处通过扎带捆扎。橡胶保温管富有弹性，可紧紧包裹氧气排出管路50，提供优异的隔热性能。在该实施例中，抽气装置40设置于压缩机仓24内，也可充分利用压缩机仓24空间，不额外占用其他地方，因此不会增大冷藏冷冻装置的额外体积，可使冷藏冷冻装置的结构紧凑。
在本发明的一些实施例中，压缩机仓24沿箱体20的横向方向延伸，抽气装置40可设置于压缩机仓24的横向一端。压缩机可设置于压缩机仓24的另一端，以使抽气装置40距离压缩机的距离比较远，减少噪音叠加和废热叠加。例如，抽气装置40可设置于压缩机仓 24的临近主门体枢转侧的一端。在本发明的另一些实施例中，抽气装置40可临近压缩机设置，抽气装置40设置于压缩机仓24的一端，且处于压缩机和压缩机仓24的侧壁之间。
在本发明的一些实施例中，抽气装置40可仅包括抽气泵41，其抽气口经由氧气排出管路50连通到所述富氧气体收集腔的排气口。在本发明的另一些实施例中，图3是根据本发明一个实施例的冷藏冷冻装置中抽气装置40的示意性分解图。如图3所示，在本发明的一些实施例中，抽气装置40还可包括安装底板42和密封盒43。安装底板42可通过多个减振脚垫44安装于压缩机仓24的底面。密封盒43安装于安装底板42。抽气泵41安装于密封盒43内。也就是说，抽气泵41可设置于一密封盒43的内部，密封盒43可通过安装底板42安装于压缩机仓24内。抽气泵41运行时，密封盒43可在很大程度上阻隔噪声和/或废热向外传播。进一步地，为提升减震减噪效果，安装底板42上还可安装多个减振脚垫44(可为橡胶材质)。减振脚垫44的数量优选为四个，四个减振脚垫44安装在安装底板42的四角处开设的脚垫安装孔内。
在本发明的一些实施例中，密封盒43内部设置有一个安装框架，安装框架与密封盒43的内壁通过多个减振垫块连接，抽气泵41固定于安装框架内部，如此以减轻抽气泵41运行时的振动和噪音。具体地，安装框架的底部设置有两个减振垫块，减振垫块套设在密封盒43底面的定位柱上。安装框架的一个相对两侧各设置有一个圆形的减振垫块，且卡设于密封盒43相应侧壁的卡槽内。安装框架的另外一相对两侧各固定一个减振垫块。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。
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筒体22的顶壁。具体地，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，筒体22的顶壁内侧具有凹陷槽。气调膜组件30设置于筒体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。进一步地，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。为了便于筒体22的制作，主板部224可与筒体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的末端为气调膜组件30的排气口。具体地，抽气孔33可设置边框的长边缘上，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内部形成的前述至少一个气流通道可以为一个或多个与抽气孔33连通的空腔。在一些实施例中，支撑框架32内部形成的前述至少一个气流通道可以具有网格结构。具体地，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，在本发明的一些实施例中，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，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。
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。
