Description

冷藏冷冻装置 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
本发明的一个目的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。
本发明的一个进一步的目的是要保证储物容器的气密性。
本发明的一个进一步的目的是要防止气调保鲜空间产生凝露。
为了实现上述至少一个目的，本发明提供了一种冷藏冷冻装置，其特征在于，包括：箱体，箱体内限定有储物空间，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，储物容器包括：顶盖，顶盖的下表面设置有凹腔；底盒，设置于顶盖下方，与顶盖共同形成气调保鲜空间；气调膜组件，设置于凹腔内部，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。
可选地，储物容器还包括：凹腔底板，可拆卸地设置于凹腔的开口处，用于部分封闭凹腔以及支撑气调膜组件。
可选地，凹腔底板设置有多个气孔，以使得气调膜组件与气调保鲜空间连通。
可选地，顶盖包括形成凹腔顶面的凹腔顶板，凹腔顶板由不锈钢板制成。
可选地，顶盖的边缘设置多个卡扣，底盒朝向顶盖的边缘对应设置多个凸起，每个凸起插入对应的卡扣内，以实现顶盖与底盒的卡接装配。
可选地，储物容器为储物抽屉，底盒的前侧面设置有抽屉口，储物抽屉还包括：抽拉部，可被推入底盒内部或由底盒内部抽出，以打开或封闭气调保鲜空间。
可选地，储物容器还包括：密封条，设置于顶盖和底盒的接合边缘之间，以密封顶盖和底盒之间的缝隙。
可选地，上述冷藏冷冻装置还包括：抽气装置，抽气装置具有抽气泵，且配置成将透入富氧气体收集腔内的气体抽排到储物容器外，并使得流出富氧气体收集腔的气体先与抽气泵的泵壳进行热交换后进入抽气泵，或使得流出富氧气体收集腔的气体先进入抽气泵并从抽气泵流出，后与抽气泵的泵壳 进行热交换。
可选地，抽气装置还包括密封盒，以容置抽气泵；且抽气泵的抽气口经由抽气管路连通到富氧气体收集腔的排气口，抽气泵的排气口与密封盒的内部空间连通；密封盒上设置有与密封盒的内部空间连通的气体排出管路。
可选地，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；且抽气装置设置于内胆和壳体之间的保温层中。
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。
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，形成气调保鲜空间的储物容器由顶盖和底盒组成，顶盖的下表面设置有凹腔，气调膜组件设置于该凹腔内。在本发明中，无需单独设置安装气调膜组件的空间，也无需在储物容器的顶面开设连通气调膜组件与气调保鲜空间的开口，因此，本发明冷藏冷冻装置的储物容器表面结构完整，基本无缝隙，保证了储物容器的气密性。另外，顶盖和底盒之间通过密封条进行密封，进一步提高了气调保鲜空间的气密性，防止气调保鲜空间的富氮气体氛围遭到破坏。
进一步地，凹腔顶板由不锈钢板制成。在存储空间内的湿度达到产生凝露的临界点时，冰箱开启冷却送风后，位于储物容器顶部的不锈钢板会迅速冷却。气调保鲜空间内空气进入凹腔内时，空气中的水分会凝聚在凹腔顶板朝向气调膜组件的一面，通过在凹腔内部设置排水管路可以将上述凝聚的水分排出，这样在气调膜组件除氧的同时，还能够去除气调保鲜空间内的部分水汽，从而避免气调保鲜空间内出现凝露的问题。
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
本发明实施例提供了一种冷藏冷冻装置，如图1和图2所示，其可包括箱体20、主门体、气调膜组件30、抽气装置40和制冷系统。
箱体60可包括内胆61、设置于内胆61外侧的壳体67，以及位于内胆61和壳体67之间的保温层。内胆61内限定出储物空间611。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60，配置成打开或关闭箱体60限定的储物空间611。主门体也可为一个门体。进一步地，储物空间611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，储物容器为储物抽屉，可设置于储物空间611的下部。如图4所示，储物抽屉包括抽屉筒体和抽拉部23。抽屉筒体进一步包括：顶盖21和底盒22，底盒22可具有前向开口。抽拉部23可滑动地设置于抽屉筒体22内，以从底盒22的前向开口可操作地向外抽出和向内插入抽屉筒体22。抽拉部23可具有抽屉端盖，抽屉端盖可与底盒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，储物容器可以为储物盒，即仅包含顶盖21和底盒22。
在本实施例中，如图5所示，顶盖21的四周边缘设置有翻边212，以便于连接底盒22，翻边212的底部端缘设置多个卡扣213。底盒22朝向顶盖21的边缘对应设置多个凸起221，凸起221插入卡扣213内，以实现顶盖21与底盒22的卡接装配。优选地，在顶盖21和底盒22的接合边缘之间增设一U形密封条25，以密封顶盖21和底盒22之间的缝隙，保证储物容器的气密性。在本实施例中U形密封条25由硅胶材料制成。U形密封条25的横截面为凹形，底盒22的上边缘设置有用于容纳U形密封条25的凹槽，U形密封条25沿底盒22的上边缘嵌入到凹槽内部，且U形密封条25的凹形结构的开口向上设置。在顶盖21卡接装配到底盒22上时，其翻边212的下边缘插入到U形密封条25的凹槽内，以实现顶盖21和底盒22之间的密封连接。在一些替代性实施实施例中，储物容器可以为储物盒，密封条25为矩形圈。
如图5所示，顶盖21的下表面设置有凹腔，上述凹腔为矩形凹腔，且设置于顶盖21的中央，以用于容纳气调膜组件30。上述凹腔的厚度略大于 气调膜组件的厚度，以使得气调膜组件30和凹腔的上表面和下表面均间隔一定距离，以便于气调保鲜空间的空气进入凹腔内部。如图6所示，储物容器还包括：凹腔底板24。凹腔底板24可拆卸地设置于凹腔的开口处，用于部分封闭凹腔以及支撑气调膜组件。在本实施例中，凹腔底板24通过卡接装配于凹腔开口处。凹腔底板24和顶盖21的凹腔共同形成用于容纳气调膜组件30的空间。凹腔底板24设置有多个气孔241，以使得凹腔内部空间与气调保鲜空间连通。
如图10所示，气调膜组件30呈平板型，设置于上述矩形凹腔内部，其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。
在本发明的一些实施例中，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；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10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。
在一些优选的实施例中，顶盖21还包括形成凹腔顶面的凹腔顶板211，凹腔顶板211由不锈钢板制成。在储物容器内部的水汽过多时，会产生凝露，食物在潮湿的环境中容易腐烂。在存储空间内的湿度达到产生凝露的临界点(相对湿度95％以上)时，冰箱开启冷却送风后，位于储物容器顶部的不锈钢板会迅速冷却(其温度远低于顶盖其他位置的温度)，气调保鲜空间内空气进入凹腔内时，空气中的水分会凝聚在凹腔顶板211朝向气调膜组件30的一面，通过在凹腔内部设置排水管路可以将上述凝聚的水分排出，这样可以解决气调空间内部由于存储高水分的果蔬物品而出现凝露的问题。上述凹腔顶板211与顶盖21一体成型，以保证储物容器的气密性。
抽气装置40可具有抽气泵41，且配置成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，可利用抽气装置40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安装有气调膜组件30的凹腔空间连通，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。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。
如图11所示，抽气装置40还可包括密封盒42，抽气泵41可设置于密封盒42内。抽气泵41的抽气口经由抽气管路51连通到富氧气体收集腔的排气口。抽气泵41的排气口411与密封盒42的内部空间连通，具体地，抽气泵41的排气口411可不接管路，裸露于密封盒42内。密封盒42上设置有与密封盒42的内部空间连通的气体排出管路52。在本发明的一些替代性实施例中，可使抽气管路51缠绕于抽气泵41的泵壳。在本发明的另一些替代性实施例中，抽气泵41的排气口可设置一吹向自身泵壳的排气管。
在本发明的一些实施例中，抽气装置40优先设置于内胆61和壳体67之间的保温层中。抽气泵41设置于保温层中可显著降低抽气泵41运行时候的噪音，给用户更好的静音体验。进一步地，壳体67可包括背板，抽气装置40设置于内胆61的后壁与壳体67的背板之间，且处于储物容器的后方，以缩短抽气泵41与气调膜组件30间的抽气管路51的长度，可以减小气调的真空度损失。
密封盒42也能够降低抽气泵41运行时产生的噪音。为了进一步降低噪 音，抽气泵41和密封盒42之间可设置多个减震垫块。密封盒42的外侧也可设置多个减震块，以安装于保温层内。
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。
