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：

具体实施方式
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7，本发明的一个实施例提供了一种冰箱。冰箱可包括箱体50、第一抽屉10、气调保鲜装置20和制冷系统。箱体50内设置有储物间室，储物间室包括冷藏间室51、冷冻间室52和变温室53。冷藏间室51的储藏温度一般在2℃至10℃之间，优先为3℃至8℃。冷冻间室52内的温度范围一般在-14℃至-22℃。变温室53可根据需求进行调整，以储存合适的食物，可选地，变温室53的温度变化范围为-24℃至10℃。
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。
如图3至图7所示，本发明的一个实施例还提供了一种用于冰箱的抽屉组件20，该抽屉组件20可用作气调保鲜装置，其可包括筒体21、第二抽屉22、气调膜组件。在一些实施例中，冰箱还可具有可与第二抽屉22替换的第一抽屉(下文详述)。筒体21内限定有抽屉空间。第二抽屉22可滑动地安装于筒体21，以从筒体21的前向开口可操作地向外抽出和向内插入筒体21。气调膜组件安装于筒体21，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。
进一步地，在一些实施例中，抽屉组件20还包括透湿装置24，筒体21上设置有连通口。透湿装置24安装于连通口，且透湿装置24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21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。
本实施例的抽屉组件20，可使抽屉空间内形成富氮贫氧以利于食物保鲜的气体氛围，且透湿膜可使抽屉22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。也就是说，该抽屉组件20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，且防止抽屉空间内部结霜，达到果蔬长期保鲜的目的。
在一些实施例中，筒体21顶壁上开设有连通口，且筒体21的顶壁内设置有与抽屉空间连通的容纳腔。气调膜组件安装于容纳腔，且富氧气体收集腔经由管路与筒体21外部连通。抽屉组件20安装于冰箱的储物间室后，储物间室后部的送风口可使气流先经由抽屉组件20的上侧向前流动，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。优选地，容纳腔设置于连通口的前侧。抽屉组件20安装于冰箱的储物间室后，可使透湿膜更靠近储物间室的送风口，送风口吹出的干燥风的湿度更低，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。
在一些实施例中，筒体21的两侧壁上均设置有自锁滑轨25；抽屉22包括本体221和安装于本体221前端的端盖222；本体221可滑动地安装于自锁滑轨25，以使本体221在完全插入筒体21后保持处于筒体21内。端盖222在本体221完全插入筒体21后与筒体21的前端接触抵靠。通过设置自锁滑轨25，保证抽屉22不轻易从筒体21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222与筒体21之间设置有密封结构26。密封结构26可为密封圈等。
在一些实施例中，筒体21包括下筒体211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。进一步地，上盖可包括上板212，以及设置于上板上侧的盖部213。盖部213和上板212之间可限定出上述容纳腔。
为了便于抽屉组件20的安装拆卸，以使抽屉组件20被更换或清洗等，抽屉组件20还包括定位装置，设置于筒体21的外表面，以在抽屉组件20安装于冰箱的储物间室内与储物间室内的定位结构配合。具体地，定位装置包括定位肋条27和至少两个定位块28。定位肋条27沿筒体21的宽度方向 延伸，且设置于筒体21的底壁下侧。至少两个定位块28沿筒体21的宽度方向依次设置，且设置于筒体21的底壁下侧；至少两个定位块28处于定位肋条27的后侧。定位肋条27的高度大于每个定位块28的高度。则储物间室内可设置有与定位装置配合的定位结构。定位结构包括定位凹槽，沿冰箱的横向方向延伸，且设置于储物间室的底壁上表面，定位肋条27插入定位凹槽。至少两个定位块28放置于储物间室的底壁上表面，或定位结构还包括用于放置至少两个定位块28的凹陷。定位装置和定位结构的结构简单，可使抽屉组件20安装牢固，也可使抽屉组件20取出和安装方便，便于抽屉组件20的取出清洗等。
在一些实施例中，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。
在一些实施例中，为了提高气调膜组件的工作效率、透湿装置24的工作效率和抽屉空间内部的制冷效率，抽屉组件20还包括风机，安装于筒体21，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，设置于容纳腔内，在筒体21的顶壁的容纳腔与抽屉空间之间的壁面中开设有多个第一通气孔和第二通气孔。多个第一通气孔与多个第二通气孔间隔开，以分别在不同位置连通容纳腔与抽屉空间。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多个第一通气孔、容纳腔和多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，离心风机位于多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。气调膜组件设置于多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21的顶壁。多个第一通气孔设置于顶壁前部，多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。
本发明还提供了一种冰箱，包括箱体、上述任一实施例中的抽屉组件20、制冷系统、抽气装置和氧气排出流路系统。箱体50内设置有储物间室，储物间室包括冷藏间室51、冷冻间室52和变温室53。冷藏间室51的储藏温度一般在2℃至10℃之间，优先为3℃至8℃。冷冻间室52内的温度范围一般在-14℃至-22℃。变温室53可根据需求进行调整，以储存合适的食物。
抽屉组件20安装于储物间室内。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。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。
在一些实施例中，储物间室包括冷藏间室51、冷冻间室52和变温室53。冷藏间室的储藏温度一般在2℃至10℃之间，优先为3℃至8℃。冷冻间室内的温度范围一般在-14℃至-22℃。变温室可根据需求进行调整，以储存合适的食物。上述任一实施例中的抽屉组件20可安装于冷藏间室、冷冻间室和/或变温室。与上述储物间室连通的送风口和回风口处均可设置风门，以在不制冷时使储物间室形成密封空间，进一步达到控制气调成分变化。
在一些优选的实施例中，储物间室内设置有滑动架30和安装于滑动架30前端的储物间室门体40。抽屉组件20的筒体21安装于滑动架30内侧且固定于储物间室内。抽屉组件20的抽屉22的端盖安装于储物间室门体40的内侧，以随储物间室门体40的打开而打开抽屉22，随储物间室门体40的关闭而关闭抽屉22。进一步地，抽屉组件20可拆卸地安装，以在不需要上述抽屉组件20时，可将抽屉组件20拆卸下，将常规搁物框安装于滑动架30，形成常规的冰箱抽屉(第一抽屉10)。
具体地，如图1和图2所示，第一抽屉10和气调保鲜装置/抽屉组件20择一地且可拆卸地设置于储物间室内。也就是说，第一抽屉10和气调保鲜装置20均可拆卸地安装于储物间室内，在使用时，用户可根据使用需求， 择一地将第一抽屉10或气调保鲜装置20安装于储物间室内，以进行使用。可选地，用户在购买时，择一地选择第一抽屉10或气调保鲜装置20作为附件进行购买。而且，用户在购买时，同时购买第一抽屉10和气调保鲜装置20，使用时择一使用。
本发明实施例的冰箱因为具有气调膜组件，可使抽屉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。且可实现根据需求对传统抽屉和气调保鲜装置20进行互换，以满足多样化的使用要求。
在本发明的一些实施例中，如图3和图4所示，筒体21上设置有连通口。气调保鲜装置20还包括透湿装置24。透湿装置24可安装于连通口，且透湿装置24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21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。且透湿膜可使第二抽屉22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。储物间室优选为变温室53。本发明的冰箱的第二抽屉22内特别用于肉类食品的短期储存。
进一步地，冰箱还可包括抽气装置，抽气装置可通过管路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。抽气装置可为真空泵，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。抽气装置可安装于箱体50，具体可处于储物间室的后部，气调保鲜装置20在安装于储物间室后，富氧气体收集腔的管路与抽气装置的进口连通。在一些实施例中，抽气装置可直接安装于筒体21，以与气调保鲜装置20形成整体件。
在本发明的一些实施例中，如图6和图7所示，冰箱还包括前门体40和滑轨组件30；前门体40通过滑轨组件30安装于箱体50，且配置成打开或关闭储物间室的前向开口；第一抽屉10放置于或可拆卸地设置于滑轨组件30。第二抽屉22包括本体221和安装于本体221前端的端盖222；端盖 222在本体221完全插入筒体21后与筒体21的前端接触抵靠；且端盖222可拆卸地安装于前门体40。当然，端盖222也可不连接于前门体40，开启时，先开启前门体40，然后在开启端盖222即可。在本发明的一些实施例中，第一抽屉10可包括前门体40，第一抽屉10和前门体40整体可拆卸地或安装于储物间室。相应地，第二抽屉22的端盖222可用于打开或关闭储物间室的前向开口以及封闭筒体21的前端。

在本发明的一些实施例中，送风口可位于筒体21的后端上边缘的后方。筒体21顶壁上开设有连通口，且筒体21的顶壁内设置有与抽屉空间连通的容纳腔。气调膜组件安装于容纳腔，且富氧气体收集腔经由管路与筒体21外部连通。气调保鲜装置20安装于冰箱的储物间室后，储物间室后部的送风口可使气流先经由气调保鲜装置20的上侧向前流动，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。优选地，容纳腔设置于连通口的前侧。气调保鲜装置20安装于冰箱的储物间室后，可使透湿膜更靠近储物间室的送风口，送风口吹出的干燥风的湿度更低，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，与上述储物间室连通的送风口和回风口处均可设置风门，以在不制冷时使储物间室内形成密封空间，进一步达到控制气调成分变化。
在本发明的一些实施例中，如图3和图4所示，筒体21的两侧壁上均设置有自锁滑轨25；第二抽屉22包括本体221和安装于本体221前端的端盖222；本体221可滑动地安装于自锁滑轨25，以使本体221在完全插入筒体21后保持处于筒体21内。端盖222在本体221完全插入筒体21后与筒体21的前端接触抵靠。通过设置自锁滑轨25，保证第二抽屉22不轻易从筒体21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222与筒体21之间设置有密封结构26。密封结构26可为密封圈等。
在本发明的一些实施例中，如图3和图4所示，筒体21包括下筒体211和上盖。下筒体211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211。上盖内侧形成有上述容纳腔。进一步地，上盖可包括上板212和设置于上板上侧的盖部213。盖部213和上板212之 间可限定出上述容纳腔。

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24的工作效率和抽屉空间内部的制冷效率，气调保鲜装置20还包括风机，安装于筒体21，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，设置于容纳腔内，在筒体21的顶壁的容纳腔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21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表面。
在一些实施例中，抽屉组件20安装于冰箱的变温室53内，且包括筒体21、抽屉22、气调膜组件和透湿装置24。筒体21内限定有抽屉空间，且筒体21上设置有连通口。抽屉22可滑动地安装于筒体21，以从筒体21的前向开口可操作地向外抽出和向内插入筒体21。气调膜组件安装于筒体21，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24安装于连通口，且透湿装置24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21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。
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22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。本实用新型的冰箱的抽屉22内特别用于肉类食品的短期储存。

在一些实施例中，筒体21的两侧壁上均设置有自锁滑轨25；抽屉22包括本体221和安装于本体221前端的端盖222；本体221可滑动地安装于自锁滑轨25，以使本体221在完全插入筒体21后保持处于筒体21内。端盖222在本体221完全插入筒体21后与筒体21的前端接触抵靠。通过设置自锁滑轨25，保证抽屉22不轻易从筒体21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222与筒体21之间设置有密封结构26。进一步地，端盖222还配置成打开或关闭变温室53的前向开口。
