图1是根据本发明一个实施例的冰箱的示意性结构图。如图1所示并参考图2至图5，本发明实施例提供了一种冰箱。冰箱可包括箱体20、抽屉组件30、制冷系统、抽气装置和氧气排出流路系统。箱体20内设置有储物间室，储物间室包括冷藏间室21、冷冻室。可选地，储物间室还可包括变温间室。冷藏间室21的储藏温度一般在2℃至10℃之间，优先为3℃至8℃。冷冻室内的温度范围一般在-14℃至-22℃。变温间室可根据需求进行调整，以储存合适的食物。
制冷系统配置成向储物间室提供冷量，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。
抽屉组件30安装于冷冻室内，且包括筒体31、抽屉32、气调膜组件和 透湿装置33。筒体31内限定有抽屉空间，且筒体31的后壁上设置有连通口311。抽屉32可滑动地安装于筒体31，以从筒体31的前向开口可操作地向外抽出和向内插入筒体31。气调膜组件安装于筒体31，且气调膜组件具有至少一个气调膜和一富氧气体收集腔，富氧气体收集腔可与真空泵等上述抽气装置连通，以使气调膜组件配置成使得抽屉空间中的氧气相对于抽屉空间中的氮气更多地透过气调膜进入富氧气体收集腔。透湿装置33安装于连通口311，且透湿装置33具有透湿膜，以使水分单向流动，且在抽屉空间内的湿度大于筒体31外的湿度时，使抽屉空间内的水分经由透湿膜流出抽屉空间。由于透湿膜设置于筒体31的后壁上，后部透湿膜安装位置选用与冷冻风道配合，可以有效的带走抽屉空间内湿度，除湿效率高，可显著防止抽屉空间内因制冷而结霜等现象发生。
具体地，氧气排出流路系统的进口可与气调膜组件的富氧气体收集腔连通，以用于排出抽屉空间内的氧气。抽气装置设置于氧气排出流路系统上，以将透入富氧气体收集腔内的气体抽排到储物容器外。抽气装置向外抽气，可使富氧气体收集腔的压力小于气调膜组件的周围空间的压力，进一步地，可使气调膜组件周围空间内的氧气进入富氧气体收集腔。由于抽屉空间与气调膜组件周围空间连通，抽屉空间内的空气会进入气调膜组件周围空间，因此也可使抽屉空间内的空气中的氧气进入富氧气体收集腔，从而在抽屉空间内获得富氮贫氧以利于食物保鲜的气体氛围。且透湿膜可使抽屉32内的水分流出，防止抽屉空间内部在制冷过程中和制冷结束后结霜。本发明的冰箱的抽屉32内特别用于肉类食品的储存，可延长食物的储存时间。
进一步地，筒体31的顶壁内设置有与抽屉空间连通的容纳腔312。气调膜组件安装于容纳腔312，且富氧气体收集腔经由管路与筒体31外部连通。为了保护透湿膜，抽屉组件30还包括安装于连通口311处的连通盖板34，连通盖板34上设置有多个连通孔；且透湿装置33安装于连通盖板34的内侧。
在本发明的一些实施例中，筒体31的两侧壁上均设置有自锁滑轨；抽屉32包括本体和安装于本体前端的端盖；本体可滑动地安装于自锁滑轨，以使本体在完全插入筒体31后保持处于筒体31内。端盖在本体完全插入筒体31后与筒体31的前端接触抵靠。通过设置自锁滑轨，保证抽屉32不轻易从筒体31出来，且可保证抽屉空间的密封性能，以形成密闭空间。进一 步地，端盖与筒体31之间设置有密封结构。进一步地，端盖还可配置成打开或关闭冷冻室的前向开口。在一些替代性实施例中，冰箱还包括冷冻室门体，配置成打开或关闭冷冻室的前向开口。端盖与冷冻室门体固定连接或者两者单独设置。
在本发明的一些实施例中，筒体31包括下筒体和上盖。下筒体具有底板、设置于底板两侧的两个侧板和设置于底板后端的后板。上盖安装于下筒体。上盖内侧形成有上述容纳腔312。例如，筒体31的顶壁，即上盖，向上凸出，以使筒体31的顶壁的内表面向上凹陷形成容纳腔312。气调膜组件通过卡扣安装于容纳腔312内。在本发明的一些实施例中，上盖内形成有上述容纳腔312。例如，上盖包括上板和安装于上板的上侧的盖部；盖板和上板之间设置有容纳腔312。
在本发明的一些实施例中，气调膜组件可呈平板型，该气调膜组件还可包括支撑框架。气调膜优选为富氧膜，可为两个，安装于支撑框架的两侧，以使两个气调膜和支撑框架共同围成富氧气体收集腔。
在本发明的一些实施例中，为了提高气调膜组件的工作效率、透湿装置33的工作效率和抽屉空间内部的制冷效率，以及使制冷均匀，抽屉组件还包括风机，安装于筒体31，配置成促使抽屉空间内部的气流流动。例如，气调膜组件可呈平板型，设置于容纳腔312内，在筒体的顶壁的容纳腔312与抽屉空间之间的壁面中开设有至少一个第一通气孔和第二通气孔。至少一个第一通气孔与至少一个第二通气孔间隔开，以分别在不同位置连通容纳腔312与抽屉空间。第一通气孔和第二通气孔均为小孔，且数量均可为多个。风机可设置于容纳腔312内，配置成促使抽屉空间的气体经由第一通气孔进入容纳腔，且使容纳腔内的气体经由第二通气孔进入抽屉空间。也就是说，风机可促使抽屉空间的气体依次经由至少一个第一通气孔、容纳腔312和至少一个第二通气孔返回抽屉空间。
优选地，风机优选为离心风机，设置于容纳腔内第一通气孔处。也就是说，离心风机位于至少一个第一通气孔的上方，且旋转轴线竖直向下，进风口正对于第一通气孔。离心风机的出气口可朝向气调膜组件。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气调膜平行于筒体的顶壁。至少一个第一通气孔设置于顶壁前部，至少一个第二通气孔设置于顶壁后部。即，离心风机设置于容纳腔的前部，气调膜组件设置于容纳腔 的后部。为了便于气流的流动，盖板部的内表面可向下延伸出多个导风肋板，以引导来自风机的气流在容纳腔内流过气调膜组件每个气调膜的背离富氧气体收集腔的外侧表面。
在本发明的一些实施例中，冷冻室的后壁上设置有冷冻室送风的送风口。送风口可设置于抽屉组件30后方的上侧，抽屉组件30的后侧或抽屉的横向两侧。优选为设置于抽屉组件30的后侧或后上侧。
抽屉组件30安装于冰箱的冷冻室后，冷冻室后部的送风口可使气流先经由抽屉组件30的后侧向前流动，可使透湿膜更靠近变送风口，以利于抽屉空间内的水分经透湿膜进入干燥的冷气流，且便于干燥的冷气流带走经透湿膜透过的水分，即可有助于抽屉空间内的水分通过透湿膜流出并被带走，除湿效率高，可显著防止抽屉空间内因制冷而结霜等现象发生。进一步地，与上述冷冻室连通的送风口和回风口处均可设置风门。
在本发明的一些实施例中，风机还可促使气流向透湿膜流动。例如，风机为离心风机，且设置于容纳腔312后，通过设置于前侧的第一通气孔吸入气流，经过后侧的第二通气孔向抽屉空间内吹出气流，且吹出的气流靠近透湿装置33，即促使气流向透湿装置流动，进而可进一步促使抽屉空间内的水分经过透湿膜流出。优选地，冷冻室制冷和风机同步开启，可进一步提高抽屉空间内的制冷效率，且有助于抽屉空间内的水分更快更多地经透湿膜流出。
在本发明的一些实施例中，抽屉组件30为多个，沿上下方向依次设置于冷冻室内。可选地，冷冻室为第一冷冻室22。箱体20内还具有第二冷冻室23和第三冷冻室24，即储物间室还包括第二冷冻室23和第三冷冻室24。第二冷冻室23设置于第一冷冻室22的一侧；第三冷冻室24设置于第一冷冻室22和第二冷冻室23的下侧。
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。
