具体实施方式
本发明实施例的冷藏冷冻装置采用利用气调保鲜技术在气调保鲜子空间内形成满足物品储放要求气体氛围。
图1是根据本发明一个实施例的冷藏冷冻装置的示意框图。该冷藏冷冻装置一般性地包括：箱体20、气调保鲜系统80、气体检测装置84、保鲜提 示装置120。其中箱体20内部限定有储物空间，储物空间内形成有密闭的气调保鲜子空间。气调保鲜系统80包括气调膜组件30以及抽气泵40。抽气泵40使气调保鲜子空间的气体经过气调膜组件30渗透，以在储物空间的气调保鲜子空间内形成利于食物保鲜的气体271内的气体氛围指标。保鲜提示装置120配置成获取气调保鲜子空间271内所保存食物的储藏信息以及气体氛围指标，并根据储藏信息以及气体氛围指标预估气调保鲜子空间271内所保存食物在气体氛围内的保鲜时间，并向用户输出包含保鲜时间的气调保鲜储物信息。上述储藏信息至少气调保鲜子空间内所保存食物的种类信息。
气调保鲜系统80采用气调膜在气调保鲜子空间内形成满足物品储放要求的气体氛围。气调膜(又称为富氧膜)的工作原理为利用空气中各组分透过气调膜时的渗透速率不同，在压力差驱动下，使空气中氧气优先通过气调膜，在现有技术中，气调膜一般用于制备氧气，从而在医疗、发酵、燃烧等领域应用。在本发明实施例中，冷藏冷冻装置则利用气调膜使氧气排出，使得气调保鲜子空间的氧气浓度下降，实现利于食物保存的气体氛围。
本实施例中，气调保鲜技术通过调节储存物所处封闭空间的气体氛围(气体成分比例或气体压力)的方式来来延长食品贮藏寿命的技术，其基本原理为：在一定的封闭空间(气调保鲜子空间)内，通过气调膜得到不同于正常空气成分的气体氛围，以抑制导致储存物(通常为食物)腐败变质的生理生化过程及微生物的活动。特别地，在本实施例中，所讨论的气调保鲜将专门针对于对气体成分比例进行调节的气调保鲜技术。
本领域技术人员均知晓，正常空气成分包括(按体积百分比计，下文同)：约78％的氮气，约21％的氧气，约0.939％的稀有气体(氦、氖、氩、氪、氙、氡)、0.031％的二氧化碳，以及0.03％的其他气体和杂质(例如，臭氧、一氧化氮、二氧化氮、水蒸气等。在气调保鲜领域，通常采用向封闭空间充入富氮气体来降低氧气含量的方式来获得富氮贫氧的保鲜气体氛围。本领域技术人员均应知晓，富氮气体是指氮气含量超过上述正常空气中氮气含量的气体，例如其中的氮气含量可为95％～99％，甚至更高；而富氮贫氧的保鲜气体氛围是指氮气含量超过上述正常空气中氮气含量、氧气含量低于上述正常空气中氧气含量的气体氛围。
虽然现有技术中也存在着气调保鲜技术，其历史可追溯到1821年德国生物学家发现水果蔬菜在低氧水平时能减少代谢作用开始。但直到目前为止，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)。因此现有技术中冰箱等小型的冷藏冷冻设备中一般仍然采用真空保鲜技术。
在本实施例中，通过上述气调膜组件经济地将气调系统小型化、静音化，从而适用于冰箱等小型的冷藏冷冻设备。图2是根据本发明一个实施例的冷藏冷冻装置的气调保鲜原理示意图，图3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4是图3所示结构的另一视角的示意性结构图。 如图所示，本发明实施例提供了一种冷藏冷冻装置，其可包括箱体20、门体(图中未示出)、气调保鲜系统80(包括气调膜组件30和抽气泵40)和制冷系统(图中未示出)。冷藏冷冻装置的箱体20内限定有储物空间，该储物空间可以按照制冷温度配置为冷藏室27、冷冻室25、变温室26等。冷藏冷冻装置可为至少具有冷藏室27和冷冻室25的冰箱。制冷系统可为常见的压缩制冷系统，其通过例如直冷和/或风冷形式向储物间室提供冷量，以使储物间室具有期望的保藏温度。在一些实施例中，冰箱冷藏室27的保藏温度可为2～9℃，或者可为4～7℃；冷冻室25的保藏温度可为-22～-14℃，或者可为-20～16℃。冷冻室25设置于冷藏室27的下方，变温室26设置于冷冻室25和冷藏室27之间。冷冻室25内的温度范围一般在-14℃至-22℃。变温室26可根据需求进行调整，以储存合适的食物。
在本实施例中，储物空间内形成有密闭的气调保鲜子空间271，该气调保鲜子空间271可以设置于上述任一种间室内，优先配置于冷藏室27和变温室26中。例如气调保鲜子空间271可以为设置在冷藏室27的下部储物空间。
门体可枢转地安装于箱体20，配置成打开或关闭箱体20限定的储物空间。为了保证气调保鲜子空间271的密封性，门体内侧还可以设置有小门，以打开或关闭气调保鲜子空间271，从而形成双层门结构。在一些可替代的实施方式中，该冷藏冷冻装置可以利用气调密封抽屉形成上述气调保鲜子空间271。气调密封抽屉可具有抽屉筒体22和抽屉本体23。利用抽屉型储物间室形成气调保鲜子空间271。
抽屉筒体22具有前向开口，并设置于储物空间内(例如冷藏室27的下部)，抽屉本体23可滑动地安装于抽屉筒体22，抽屉本体23的前端设置有端板，与抽屉筒体22配合，可以封闭气调保鲜子空间271的开口。一种具体的方式为抽屉本体23可从抽屉筒体22的前向开口可操作地向外抽出和向内推入。端板通过密封结构使得气调保鲜子空间271的开口封闭。
在本发明的一些实施例中，抽屉筒体22可以与靠抽屉本体23的端板之间形成密封部，该密封部可以适当漏气实现气压平衡。在一些其他实施例中可以通过在抽屉筒体22上设置毫米级的微孔或者单向阀等方式保证气压平衡。
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。压缩机安装于压缩机舱24内。蒸发器配置成直接或间接地向储物空间内提供冷量。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，以向储物空间进行循环制冷。由于此类制冷系统本身是本领域技术人员习知且易于实现的，为了不掩盖和模糊本申请的发明点，后文对制冷系统本身不作更多赘述。
气调膜组件30具有气调膜，并限定有富氧气体收集腔，在富氧气体收集腔的压力小于周围环境的压力时，周围环境的气体(大部分氧气)透过气调 膜进入气调富氧气体收集腔。具体地，气调膜的另一侧可直接与气调保鲜子空间271接触，或与连通至气调保鲜子空间271的循环流道(或循环空间)接触，从而可在富氧气体收集腔的压力小于子空间的压力时，使气调保鲜子空间271内空气中的气调气体透过气调膜进入富氧气体收集腔，在使用富氧膜的情况下，气调保鲜子空间271的氧气被抽出，从而使气调保鲜子空间271形成贫氧的气体氛围。
抽气泵40可以设置于压缩机舱24内，抽气泵40的进口端经由管路50与气调膜组件30的富氧气体收集腔连通，配置成将富氧气体收集腔的气体向外抽出，以使气调保鲜子空间271内的至少部分氧气通过气调膜进入富氧气体收集腔，从而降低气调保鲜子空间内的氧气浓度。抽气泵40配置成将富氧气体收集腔富含氧气的气体抽出，降低气调保鲜子空间271的氧气浓度。以在气调保鲜子空间271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子空间271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，不会降低子空间内物品的受冷效率，可使果蔬等有效得到储存。抽气泵40设置于压缩机舱24内，可充分利用压缩机舱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，抽气泵40和压缩机可以分别设置于压缩机舱24的两侧，彼此间隔，以使抽气泵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，抽气泵40可设置于压缩机舱24的临近门体枢转侧的一端。当冷藏冷冻装置为对开门冰箱时，抽气泵40可设置于压缩机舱24的任意位置。在本发明的另一些实施例中，抽气泵40也可以邻近压缩机设置，例如抽气泵40设置于压缩机舱24的一端，且处于压缩机和压缩机舱24的侧壁之间。
在本发明的一些实施例中，抽气泵40可以安装于密封盒内，密封盒可通过安装底板安装于压缩机舱24内。密封盒可在很大程度上阻隔抽气泵40的噪声和/或废热向外传播。
图5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，以及图6是图5所示结构的示意性分解图，气调膜组件30可设置于抽屉筒体22的筒体内，优选地设置于抽屉筒体22的顶壁。具体地抽屉筒体22的顶壁内设置有与气调保鲜子空间271连通的容纳腔31。抽屉筒体22的顶壁的容纳腔31与气调保鲜子空间271之间的壁面中开设有至少一个第一通气孔222和与至少一个第一通气孔222间隔开设的至少一个第二通气孔223，以分别在不同位置连通容纳腔31与气调保鲜子空间271，容纳腔31与气调保鲜子空间271经由至少一个第一连通孔222和至少一个第二连通孔223连通；气调膜组件30设置于容纳腔31内，可以设置于至少一个第二连通孔223的上方。容纳腔31构成与气调保鲜子空间271连通的循环空间，以使气调膜组件 30中的气调膜36与气调保鲜子空间271内的气体接触。第一连通孔222和第二连通孔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，为了促使气调保鲜子空间271与容纳腔31内的气体流动，第一密闭组件71的容纳腔31内还可以设置风机60，风机60用于形成依次经由至少一个第一通气孔222、容纳腔31和至少一个第二通气孔223并返回所述气调保鲜子空间271的气流，从而促使气调保鲜子空间271的气体经由第一连通孔222进入容纳腔31，且使容纳腔31内的气体经由第二连通孔223进入气调保鲜子空间271，从而形成经由气调膜组件30的气流。
风机60置于容纳腔31的位置可以处于至少一个第一连通孔222的上方，其促使气调保鲜子空间271的气体经由至少一个第一连通孔222进入容纳腔31，且使容纳腔31内的气体经由至少一个第二连通孔223进入气调保鲜子空间271，以由气调膜组件30从通过其的气体中析出的氧气。
风机60优选采用离心风机，可以设置于气体收集腔31内第一连通孔222处。也就是说，离心风机60位于至少一个第一连通孔222的上方，且进风口正对于第一连通孔222。离心风机60的出气口可朝向气调膜组件30。至少一个第二连通孔223可位于气调膜组件30的下方。
抽屉筒体22的顶壁包括下板部224和盖板部225，共同限定出容纳腔31，例如下板部224的上表面可以形成凹陷槽，盖板部225盖设于凹陷槽，以形成容纳腔31。至少一个第一连通孔222设置于顶壁前部，至少一个第二连通孔223设置于顶壁后部。离心风机60设置于容纳腔31的前部，气调膜组件30设置于容纳腔31的后部。
气调膜组件30具有气调膜36和富氧气体收集腔，且气调膜36的一侧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36的另一侧的压力时，使气调膜36的另一侧的空气中的氧气透过气调膜36进入富氧气体收集腔。具体地，该气调膜组件30可以与连通至气调保鲜子空间271的循环流道(即容纳腔31)接触，从而可在富氧气体收集腔的压力小于气调保鲜子空间271的压力时，使容纳腔31内气体(来源于所述气调保鲜子空间271)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进入富氧气体收集腔，也即将风机60形成气流中的氧气相对于氮气更多地透过气调膜进入富氧气体收集腔。多个第一密闭组件71可以采用相同的结构，具体的尺寸可以根据需要设置为相同或不同。
图7是根据本发明一个实施例的冷藏冷冻装置中气调膜组件30的分解图，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。支撑框架32具有相互平行的第一表面和第二表面，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。
气调膜36可为两层，分别铺设于支撑框架32的两侧，以使封闭富氧气 体收集腔，每层气调膜36可以包括一张或多张气调膜层叠形成。气体透过气调膜36是一个复杂的过程，其透过机制一般是气体分子首先被吸附到气调膜36的表面溶解，然后在气调膜36中气调膜中溶解和扩散系数的差异来实现气体的分离。当气体由于气调膜36两侧的压力差作用下，渗透速率快的氧气在气调膜36的渗透侧被富集，从而汇聚于富氧气体收集腔内。
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，且内部形成有与第一表面和第二表面连通的多个气流通道。两个气调膜36分别铺设在支撑框架32的第一表面和第二表面上，以与支撑框架32的多个气流通道共同封闭形成富氧气体收集腔。
在本发明的一些实施例中，支撑框架32包括与前述多个气流通道连通的抽气孔33，设置于边框32上，以允许富氧气体收集腔中的氧气被输出。抽气孔33与抽气装置41连通。气调膜36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内部形成的前述多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内部形成的前述多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，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。
例如支撑框架32具有相互平行的第一表面和第二表面，支撑框架32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以连通第一表面和第二表面的多个气流通道。也就是说，该多个气流通道包括在第一表面上延伸的多个第一气流通道、在第二表面上延伸的多个第二气流通道、以及贯穿支撑框架32以连通第一表面和第二表面的多个第三气流通道。或者也可以理解为，支撑框架32形成有在第一表面上延伸的多个第一气流通道和在第二表面上延伸的多个第二气流通道，且第一气流通道与第二气流通道之间通过第三气流通道连通。所有的气流通道共同形成富氧气体收集腔。
一张或多张气调膜形成两个平面形气调膜层，分别铺设在支撑框架的第一表面和第二表面上，从而构成平板形的气调膜组件30。
支撑框架32形成有与上述气流通道连通的抽气孔33，抽气孔33连通富氧气体收集腔，用于连接抽气泵40的进口端，从而允许富氧气体收集腔中的富氧气体被输出。在抽气泵40运行时，富氧气体收集腔38中处于负压状态，气调膜组件30外侧空气中的氧气会持续透过气调膜36进入富氧气体收集腔中。支撑框架32整体上可大致呈矩形框架。
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。也就是说，前述多个第二肋板设置在前述多个第一肋板的一侧表面上。前述多个第一肋板和前述多个第二肋板相背的表面分别形成第一表面和第二表面；即，前述多个第一肋板和前述多个第二肋板相背的表面形成第一表面；前述多个第二肋板和前述多个第一肋板相背的表面形成第二表面。相邻的第一肋板之间、相邻的第二肋板之间、以及相邻的第一肋板与第二肋板之间的间隙形成前述多个气流通道。其中，两个相邻的第一肋板之间的间隙形成在第一表面上延伸的第一气流通道，两个相邻的第二肋板之间的间隙形成在第二表面上延伸的第二气流通道，相邻的第一肋板与第二肋板之间的间隙形成贯穿支撑框架32连通第一表面和第二表面的第三气流通道。即，由所有第一肋板和所有第二肋板形成的交叉结构形成前述多个气流通道。
上述支撑框架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36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。
抽气孔33可在边框的纵向中部设置于边框的横向一侧。这样设置相当于从气调膜组件30的中部抽气，有利于气调膜36均匀透气。抽气孔33可为台阶孔或者说阶梯孔，以在其通过软管与抽气泵40连接时，保证连接部位的气密性。
此外，支撑框架32的上述结构保证了气调膜36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。
抽气泵40的进气端经由抽气管路50分别连接抽气孔33，以连通至多个第一密闭组件71内的气调膜组件30的富氧气体收集腔，并配置成将富氧气体收集腔的气体向外抽出，以使气调保鲜子空间271内的氧气含量不断降低，从而在气调保鲜子空间271内形成富氮贫氧以利于食物保鲜的气体氛围。抽气泵40可以设置于压缩机舱24内，可充分利用压缩机舱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。
气体检测装置84设置于气调保鲜子空间271内，并配置成检测气调保鲜子空间271内的气体氛围指标。气体检测装置84可以选用其可以选用隔膜式伽伐尼电池式、电化学、催化燃烧、恒定电位电解式等多种类型的氧气浓度传感器，在一些可选实施例中，气体检测装置84也可以使用气体分析仪进行 替换，以用于测量气调保鲜子空间271内的气体含量，包括氧气含量，也可以包括氮气含量、二氧化碳含量等。气体检测装置84可以根据需要进行配置。
保鲜提示装置120可以利用冰箱门体的显示板来实现，直接输出气调保鲜储物信息。另外在另一些实施例中，保鲜提示装置120也可以设置于限定气调保鲜子空间271的气调密封抽屉的本体22的前面板处。
图8是根据本发明一个实施例的冷藏冷冻装置的控制系统的示意框图。控制器110分别与抽气泵40、风机60、气调保鲜子空间开闭检测装置82、气体检测装置84、冷藏室开闭检测装置72、温度传感器84、保鲜提示装置120。
气调保鲜子空间开闭检测装置82和冷藏室开闭检测装置72可以用于分别检测气调保鲜子空间271所在的间室(例如冷藏室27)以及气调保鲜子空间271被开闭的事件，其使用霍尔器件、磁敏器件来检测门体的开合动作或者抽屉本体23端板与抽屉筒体22的开合动作。在使用抽屉型储物间室作为气调保鲜子空间271时，气调保鲜子空间开闭检测装置82可以分别设置于抽屉本体23的端板和抽屉筒体22上；冷藏室开闭检测装置72可以分别设置于箱体20以及对应的门体上。
温度传感器84用于检测冷藏冷冻装置内储藏间室的温度，例如可以包括设置于冷藏室27内的冷藏温度传感器、冷冻室25内的冷冻温度传感器、变温室26内的变温传感器。温度传感器84检测的温度值可以用于与设定温度进行比较，以确定是否需要制冷系统(包括压缩机以及冷藏风机、冷冻风机、各风门)启动。
保鲜提示装置120可以使用显示屏等方式向用户进行信息提示。保鲜提示装置120获取的储藏信息至少包括气调保鲜子空间内所保存食物的种类信息，另外可以确定食物已放入气调保鲜子空间的时间。保鲜提示装置120可以根据种类信息获取该类食物的保鲜数据库，保鲜数据库中预先保存有该类食物在不同气体氛围下的保鲜时间；根据气体氛围指标在保鲜数据库查询对应的保鲜期限；将保鲜期限减去食物已放入气调保鲜子空间的时间的剩余的保鲜时间。保鲜数据库的数据可以根据预先对各类食物的测试确定得到。保鲜数据库的数据可以包括各类食物在不同氧气浓度氛围内所能保持新鲜程度的时间。
保鲜数据库中还可以保存有该类食物的最佳储藏条件。控制器110根据最佳储藏条件控制气调保鲜系统的启停，以使气调保鲜子空间的气体氛围符合最佳储藏条件。
通过对食物保鲜特性的研究，发明人发现氧气与食品的氧化作用、呼吸作用均密切相关，传统的观点认为氧气浓度越低，越有利于食品的保存，然而经过发明人通过大量测试的总结得出，传统的观点并非正确，每种食品均有最佳的保存气体氛围。表1示出了一部分蔬果的最佳储藏环境的氧气范围：
表1
蔬果种 氧气浓度
类 (单位％)
菠菜 1
卷心菜 2.5-5
甘蓝 2.5-5
花椰菜 2.5
芦笋 2.5-5
莴苣 1
苹果 3
梨 1
西红柿 3
青豆 2
通过表1可以看出，不同的食物具有不同的优选保存环境，因此本实施例中，可以预先根据食物的优选保存环境进行测试，控制器110可以确定出放入气调保鲜子空间271的食物种类对应的最佳储藏条件，该最佳储藏条件至少包括储藏食物对应的最佳氧气浓度范围。氧气浓度范围包括氧气浓度上限和氧气浓度下限，控制器110的控制原理为：在气调保鲜子空间271的氧气浓度等于或低于氧气浓度下限时，关闭气调保鲜系统80；在气调保鲜子空间271的氧气浓度高于或等于氧气浓度上限时，启动气调保鲜系统80。
控制器110，作为本实施例的冷藏冷冻装置的控制核心，可以通过各种微处理器(包括单片机、数字信号处理器等)及其附属电路(电源、存储器、时钟电路)通过配置相应的控制程序来实现。
控制器110还可以对制冷系统和气调保鲜系统80的控制优先级进行控制，在满足制冷温度的要求的前提下进行气调保鲜控制。例如可以通过设置保鲜运行标识来确定是否允许气调保鲜系统80启动工作。
保鲜运行标识可以为控制器110某一寄存器中标识位，其至少包括两种状态：分别指示出允许气调保鲜系统80运行和禁止气调保鲜系统80运行。在进行气调保鲜控制时，控制器110可以首先获取气调保鲜系统80的保鲜运行标识。保鲜运行标识根据冷藏冷冻装置的运行事件进行设置，并且指示出是否允许气调保鲜系统80运行。冷藏冷冻装置的运行事件至少包括：冷藏冷冻装置的运行时刻、制冷系统的启停事件、储物空间被开闭的事件、气调保鲜子空间271被开闭的事件。
上述冷藏冷冻装置的运行事件可以通过冷藏冷冻装置设置的各种传感器、检测装置以及控制器110下发的控制指令进行确定。例如冷藏冷冻装置的运行时刻可以利用冷藏冷冻装置的时钟确定，制冷系统的启停事件可以通过检测压缩机的状态或者通过控制器110向制冷系统发送的控制指令确定、储物空间被开闭的事件可以通过冷藏室开闭检测装置72来进行检测、气调保鲜子空间271被开闭的事件可通过气调保鲜子空间开闭检测装置82来进行检测。
在保鲜运行标识为允许气调保鲜系统80运行的情况下，控制器110可以判断气调保鲜系统80是否满足预设开机条件，并在满足开机条件的情况下，启动气调保鲜系统80以对气调保鲜子空间271的气体进行调节，直至气调保鲜系统80达到预设的关机条件。
控制器110设置上述保鲜运行标识的过程可以包括：在初始状态下，可以将上述保鲜运行标识设置为禁止状态。另外在制冷系统启动后，将保鲜运行标识设置为禁止状态，并在制冷系统被关闭并延时一定时间后，将保鲜运行标识设置为允许状态。在进入冷藏冷冻装置的频繁开门时段后，将保鲜运行标识设置为禁止状态，并且在等待频繁开门时段经过后，将保鲜运行标识设置为允许状态。在储物空间被打开后，将保鲜运行标识设置为禁止状态，并且在储物空间被关闭的延时一定时间后，再将保鲜运行标识设置为允许状态。
通过以上设置，可以避免气调保鲜系统80在以下情况下启动：与制冷系统同时处于启动状态、在用户经常取放东西的时间段内启动、在用户打开储物间室的情况下启动。冷藏冷冻装置的频繁开门时段可以根据用户的使用习惯进行总结得出，例如以天为周期，将每天中打开次数超过预定次数的时间作为上述频繁开门时段。另外在另一可选实施例中，也可以以周为单位进行总结，避免在用户经常开启冷藏冷冻装置门体的时间段启动气调保鲜系统80。
控制器110通过上述的控制逻辑，使制冷系统优选启动，保证储藏空间的温度符合储物要求，然后相应控制气调保鲜系统80，避免了气调保鲜系统80与制冷系统互相影响，同时避免了对应用户正常使用冷藏冷冻装置产生影响，提高了用户的使用体验。
本实施例还提供了一种冷藏冷冻装置气调保鲜储物信息的输出方法，该方法可以用于对上述实施例的冷藏冷冻装置进行信息提示，及时向用户报告气调保鲜的情况，满足用户的使用需求。图9是根据本发明一个实施例的冷藏冷冻装置气调保鲜储物信息的输出方法的示意图。该实施例的冷藏冷冻装置气调保鲜储物信息的输出方法一般性地可以包括：
步骤S902，获取气调保鲜子空间内所保存食物的储藏信息以及气体氛围指标，储藏信息至少气调保鲜子空间内所保存食物的种类信息，这些种类信息可以由用户进行设置得出(例如用户在放入食品后通过冷藏冷冻装置的触摸屏进行设置)，也可以通过图像识别(用户放入食物后，经过气调保鲜子空间271内的拍摄装置拍照，经过图像识别确定食物种类)等方式自动确定。
步骤S904，根据储藏信息以及气体氛围指标预估气调保鲜子空间271内所保存食物在气体氛围内的保鲜时间；
步骤S906，向用户输出包含保鲜时间的气调保鲜储物信息。
储藏信息还可以包括已放入气调保鲜子空间的时间，步骤S904的预估步骤还可以包括：根据种类信息获取该类食物的保鲜数据库，并根据气体氛围指标在保鲜数据库查询对应的保鲜期限；将保鲜期限减去食物已放入气调保鲜子空间的时间从而得到剩余的保鲜时间。保鲜数据库中预先保存有该类食 物在不同气体氛围下的保鲜时间；根据气体氛围指标在保鲜数据库查询对应的保鲜期限；将保鲜期限减去食物已放入气调保鲜子空间的时间的剩余的保鲜时间。保鲜数据库的数据可以根据预先对各类食物的测试确定得到。保鲜数据库的数据可以包括各类食物在不同氧气浓度氛围内所能保持新鲜程度的时间。
保鲜数据库中还保存有该类食物的最佳储藏条件，在步骤S902之后可以根据最佳储藏条件控制气调保鲜系统的启停，以使气调保鲜子空间的气体氛围符合最佳储藏条件。储藏条件至少包括氧气浓度上限值和氧气浓度下限值，从而在气调保鲜子空间271的氧气浓度高于或等于氧气浓度上限的情况下，启动抽气泵40和风机60。在气调保鲜子空间271的氧气浓度高于或等于氧气浓度上限的情况下，关闭抽气泵40和风机60，完成气调保鲜运行，使气调保鲜子空间271内的氧气浓度维持在氧气浓度上限值和氧气浓度下限值之间的范围内。
在预估保鲜时间的步骤之后还包括：根据种类信息预估该类食物暴露于空气环境中的保鲜时间；根据气调保鲜子空间271内所保存食物的保鲜时间与该类食物暴露于空气环境中的保鲜时间确定气调保鲜系统80的保鲜效果，并向用户输出。
另外在预估保鲜时间的步骤之后，还可以获取气调保鲜子空间271的被开闭事件；根据被开闭事件对食物放入气调保鲜子空间271后气调保鲜子空间271被开启的次数进行计数，根据气调保鲜子空间271被开启的次数对预估出的保鲜时间进行修正。由于开启气调保鲜子空间271，会导致气调保鲜子空间271的气体氛围被破坏，导致保鲜时间缩短，因此可以根据气调保鲜子空间271被开启的次数减少相应的保鲜时间。每次开启减少一定的保鲜时间。
在食物放入气调保鲜子空间271后气调保鲜子空间271被开启的次数超过预设次数的情况下，输出提示减少开启气调保鲜子空间271的提示信息。例如用户在一天内开启气调保鲜子空间271的次数超过4次的情况，就可以输入提示信息。
具体的信息输出的内容可以为：在正常储藏物品时，保鲜提示装置120可以显示“食品在本环境下可保鲜xx天”，具体的天数可以根据气调保鲜子空间271内的氧气浓度确定。在与空气中该类食物的保鲜时间进行比较后，保鲜提示装置120可以显示“恭喜您延长了保鲜xx天”。如果用户每天开启气调保鲜子空间的次数较多，则建议用户在气调保鲜子空间271内尽量存放需要长时间放置的食品，并提示“由于打开次数较多，保鲜时间减少xx小时”。在用户输入所放入食物的种类后，保鲜提示装置120可以显示“食品在本环境下可保鲜xx天”或者“本环境为您延长保鲜xx天”。
本实施例的冷藏冷冻装置气调保鲜储物信息的输出方法根据食物的储藏信息以及气体氛围指标预估气调保鲜子空间271内所保存食物在气体氛围内的保鲜时间，从而向用户输出包含保鲜时间的气调保鲜储物信息，使得用户 可以了解气调保鲜系统的优点，有助于气调保鲜功能的推广使用。
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。
