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201611110830.5，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。
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。

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隐去门体的示意性正视图。图2是根据本发明一个实施例的冷藏冷冻装置隐去门体及部分内部结构的示意性正视图。图3是图2所示装置的另一视角的示意性结构图。图4是根据本发明一个实施例的冷藏冷冻装置中储物容器 的示意图。如图1至图4所示，本发明实施例提供了一种冷藏冷冻装置10，其可包括箱体20、主门体、气体分离器30、抽气泵41和制冷系统。
箱体20内限定有储物空间200。例如，箱体20可包括内胆，内胆内限定出储物空间200。主门体可转动安装于箱体20，配置成打开或关闭箱体20限定的储物空间200。进一步地，储物空间200内设置有储物容器21，储物容器21内具有气调保鲜空间210。气调保鲜空间210可为密闭型空间或近似密闭型空间。优选地，储物容器21为抽屉组件。储物容器21可包括抽屉筒体22和抽屉本体23。抽屉筒体22可具有前向开口，且设置于储物空间200内，具体可设置于储物空间200的下部。如本领域技术人员可认识到的，抽屉筒体22也可设置于储物空间200的中部或上部。抽屉本体23可滑动地设置于抽屉筒体22内，以从抽屉筒体22的前向开口可操作地向外抽出和向内插入抽屉筒体22。抽屉本体23可具有抽屉端盖，抽屉端盖可与抽屉筒体22的开口相配合，以进行气调保鲜空间210的密闭。在一些替代性实施实施例中，储物容器21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。压缩机安装于箱体20内限定出的压缩机仓24内。蒸发器配置成直接或间接地向储物空间200内提供冷量。例如当该冷藏冷冻装置10为家用压缩式直冷冰箱时，蒸发器可设置于内胆的后壁面外侧或内侧。当该冷藏冷冻装置10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200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200进行循环制冷。
图5是根据本发明一个实施例的冷藏冷冻装置中气体分离器的示意性剖视图。如图5所示，气体分离器30具有气调膜300、第一气体收集腔310和第二气体收集腔320。气调膜300可以为富氧膜。气调膜300位于第一气体收集腔310和第二气体收集腔320之间，且气调膜300的内侧表面朝向第二气体收集腔320，第一气体收集腔310配置成受控地与储物空间200连通，以在第一气体收集腔310的压力小于储物空间200的压力时，使储物空间200内的空气进入第一气体收集腔310，气调膜300配置成当第一气体收集腔310的压力大于第二气体收集腔320的压力时，使进入第一气体收集腔310内的空气中的氧气相对于其中的氮气更多地透过气调膜300进入第二气体收集腔320，以在第二气体收集腔320内形成富氧气体，第一气体收集腔310还配置成受控地与气调保鲜空间210连通，以在第一气体收集腔310的压力大于气调保鲜空间210的压力时，使进入第一气体收集腔310内的除去已透过气调膜300进入第二气体收集腔320的富氧气体的其余气体进入气调保鲜空间210，从而在气 调保鲜空间210内获得富氮贫氧以利于食物保鲜的气体氛围。抽气泵41，经由管路50与第二气体收集腔320连通，配置成促使第二气体收集腔320内的气体流出气体分离器30。
气调膜对于所有气体都是可以渗透的，只是不同气体具有不同的渗透程度。气体透过气调膜是一个复杂的过程，其透过机制一般是气体分子首先被吸附到气调膜的表面溶解，然后在气调膜中扩散，最后从气调膜的另一侧解吸出来。气调膜分离技术依靠不同气体在气调膜中溶解和扩散系数的差异来实现气体的分离。在本发明中，气调膜300可以为富氧膜。由此，当混合气体在一定的驱动力(气调膜两侧的压力差或压力比)作用下，渗透速率相对快的气体如氧气、氢气、氦气、硫化氢、二氧化碳等透过气调膜后，在气调膜的渗透侧被富集，而渗透速率相对慢的气体如氮气、一氧化碳等被滞留在气调膜的滞留侧被富集从而达到混合气体分离的目的。
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。这里，本领域技术人员均知晓，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。
具体地，抽气泵41通过向外抽气使得第二气体收集腔320内的气体经由管路50流出，从而使得第二气体收集腔320的压力减小。当第二气体收集腔320的压力小于第一气体收集腔310的压力时，第一气体收集腔310内空气中的渗透速率相对快的氧气等气体在压力和气调膜300的作用下进入到第二气体收集腔320内。此时，由于第一气体收集腔310内的部分氧气进入了第二气体收集腔320，第一气体收集腔310内形成仅含有少量氧气或者不含氧气的其他渗透速率相对慢的气体，也即是富氮气体。进一步地，第一气体收集腔310的压力由于其内气体中氧气的减少而减小，使得储物空间200内的空气因压差进入第一气体收集腔310内，并在抽气泵41及气调膜300的作用下使进入第一气体收集腔310的空气中的渗透速率相对快的氧气等气体持续排入第二气体收集腔320。也就是说，抽气泵41通过向外抽气使得储物空间200内空气持续进入气体分离器30，并在气调膜300的作用下，在第一气体收集腔310内形成除去已进入第二气体收集腔320的气体的其余气体，也即是富氮气体。此时，第一气体收集腔310可受控与气调保鲜空间210连通，以使该富氮气体充入气调保鲜空间210。
本发明的冷藏冷冻装置10可使储物空间200的气调保鲜空间210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。
在本发明的一些实施例中，气体分离器30可包括集气盒31。集气盒31内设置有水平放置的支撑框架32，支撑框架32与集气盒31的上半部盒体共同限定出第一气体收集腔310，支撑框架32与集气盒31的下半部盒体共同限定出第二气体收集腔320。进一步地，气调膜300可水平设置于支撑框架32上。
在本发明的一些实施例中，集气盒31上还可设置有三个可受控打开的通气孔。三个通气孔可分别为用于使储物空间200内空气进入第一气体收集腔310的第一通气孔、使富氮气体由第一气体收集腔310充入气调保鲜空间210的第二通气孔和使富氧气体流出第二气体收集腔320的第三通气孔。
也就是说，第一气体收集腔310可通过第一通气孔与储物空间200连通。具体地，当第一气体收集腔310的压力小于储物空间200的压力时，第一通气孔受控打开。此时第二通气孔受控关闭，以使第一气体收集腔310的压力增大，并形成大量的富氮气体。可以理解的是，由于氮气等渗透速率相对慢的气体无法大量地通过气调膜300进入第二气体收集腔320，第一气体收集腔310的压力会持续升高。当第一气体收集腔310的压力大于或等于储物空间200的压力时，第一通气孔可受控地关闭，此时第二通气孔可受控打开，以使第一气体收集腔310内的大量富氮气体流向气调保鲜空间210。第三通气孔可在第一通气孔和/或第二通气孔打开时一直保持打开状态，以使第二气体收集腔320内的富氧气体及时被抽气泵41抽出，从而促使储物空间200内空气持续流入第一气体收集腔310。
在本发明的一些实施例中，第二通气孔也可配置成延时打开。具体地，当第一通气孔打开时，第二通气孔等待一预设时间后再打开，以使第一气体收集腔310内形成足够的富氮气体。
在本发明的一些实施例中，冷藏冷冻装置10还可包括轴流风机60。轴流风机60可设置在第一气体收集腔310至气调保鲜空间210的流动路径上，配置成受控地启动，并促使进入第一气体收集腔310内的气体中的除去已透过气调膜300进入第二气体收集腔320的富氧气体的其余气体加速流向气调保鲜空间210。具体地，轴流风机60设置为，其进风口朝向第一气体收集腔310，其出风口朝向气调保鲜空间210，以促使从第一气体收集腔310内流 出的富氮气体加速流向气调保鲜空间210。进一步地，轴流风机60可配置成随第二通气孔的打开而开启。
在本发明的一些实施例中，气体分离器30可设置于储物空间200内部，且位于抽屉筒体22的外部后侧。也就是说，气体分离器30可独立整体地设置于气调保鲜空间210的外部，从而使其便于安装和拆卸。
在本发明的一些实施例中，抽屉筒体22上可开设有多个气压平衡孔221，储物空间200和气调保鲜空间210经由多个气压平衡孔221连通。气压平衡孔221可为毫米级的微孔，例如每个气压平衡孔221的直径为0.1mm至3mm。设置多个气压平衡孔221可使气调保鲜空间210内的压力不至于太高，具体地，当气调保鲜空间210的压力过大时，气调保鲜空间210内的少量气体可经由气压平衡孔221流入储物空间200内，以避免气调保鲜空间210的压力过高。当少量气体流出气调保鲜空间210时，气调保鲜空间210内富氮贫氧的气体氛围并不会发生改变，或改变极小可以忽略不计。
在本发明的一些实施例中，抽屉本体23和抽屉筒体22之间设置有锁定装置、把手和把手定位装置。锁定装置包括设置于抽屉端盖两侧的枢转锁扣、设置于抽屉筒体22上的两个扣合部，以及卡接促使装置。每个扣合部可为凸起。卡接促使装置可用于促使两个枢转锁扣朝卡接于各自相应的扣合部的方向(即各自的第一方向)转动。把手水平延伸，且可沿竖直方向可滑动地安装于抽屉端盖。而且，在抽屉本体23处于关闭状态时，把手所处的位置可为把手的初始位置。且把手配置成在其初始位置时，其两端分别与两个枢转锁扣接触抵靠，以阻止每个枢转锁扣沿与各自相应的第一方向相反的另一方向转动，以使所述枢转锁扣与所述扣合部保持配合状态，从而将所述抽屉本体23锁定于所述抽屉筒体22。进一步地，当把手向上或向下移动至解除保持锁定位置，即从初始位置移动到解除保持锁定位置后，可允许每个枢转锁扣沿与各自相应的第一方向相反的另一方向转动，以允许在向外拉动抽屉本体23时，枢转锁扣转动脱离相应的扣合部，从而允许打开抽屉本体23。把手定位装置配置成在当把手运动到各个预定的位置处后，使把手保持处于该位置处，主要是初始位置和解除保持锁定位置。当打开抽屉本体23时，用户先使把手向上或下运动到解除保持锁定位置，把手定位装置使把手保持处于该位置，用户可向外拉开抽屉本体23。当关闭抽屉本体23时，用户先使抽屉本体23关闭，然后使把手向下或上回到初始位置，把手定位装置使把手保持处于该位置，从而使抽屉本体23和抽屉筒体22保持处于锁定状态。
为了进一步使把手的运动平稳，把手的两端还分别设置有导向杆和滑块，导向杆沿竖直方向延伸。抽屉本体23还包括两组滑道，每组滑道至少有三个沿竖直方向延伸的滑槽，以 使导向杆的两侧分别具有一个滑槽，滑块在其余的滑槽上运动，或使滑块的两侧分别具有一个滑槽，导向杆在其余的滑槽上运动。例如，每组滑道可包括四个滑槽，导向杆的前后两侧分别具有一个滑槽，滑块的横向两侧(即左右两侧)分别具有一个滑槽。
在本发明的一些实施例中，储物空间200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还可限定出冷冻空间25和变温空间26，冷冻空间25设置于储物空间200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200也可为冷冻空间25或变温空间26，也就是说，储物空间200的温度范围可控制在-14℃至-22℃或根据需求进行调整。
在本发明的一些实施例中，抽气泵41可设置于压缩机仓24内，进而可以充分利用压缩机仓24的空间，不额外占用其他地方，因此不会增大冷藏冷冻装置10的额外体积，可使冷藏冷冻装置10的结构紧凑。
具体地，抽气泵41可设置于压缩机仓24的一端。压缩机可设置于压缩机仓24的另一端，以使抽气泵41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41可设置于压缩机仓24的临近主门体枢转侧的一端。当冷藏冷冻装置10为对开门冰箱时，抽气泵41可设置于压缩机仓24的任意一端。在本发明的另一些实施例中，抽气泵41临近压缩机设置，抽气泵41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。
图6是根据本发明一个实施例的冷藏冷冻装置中抽气泵组件的示意性分解图。如图6所示，在本发明的一些实施例中，冷藏冷冻装置10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。密封盒43、安装底板42和抽气泵41也可被称为抽气泵组件40。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，管路50可包括竖直管段。竖直管段设置于储物空间200的后方，且竖直管段的下端与抽气泵41的进口连通，竖直管段的上方与气体分离器30的第二气体收集腔320连通。竖直管段可临近箱体20中侧壳和背板设置，竖直管段上可套装有保温套或保温管，可防止竖直管段内氧气中的冷量传递至侧壳和背板，从而可防止产生凝露。
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。
