Description

一种氮气保鲜抽屉
技术领域
本发明涉及家用制冷设备领域，特别涉及一种用于冰柜内部的氮气保鲜抽屉。
背景技术
氮气保鲜属于气调保鲜技术范畴，能够通过人为调节、控制箱体 ( 或库体 ) 内的气体成分比例、温度、湿度、气压，最大限度延缓食品的新陈代谢、后熟过程 ( 包括相应的化学反应 ) ，从而保持食品品质、色泽、口感基本不变，达到长期保持新鲜的效果。氮气保鲜技术是利用 N2 为惰性气体，一般不与食品发生化学作用的特性，达到延长食品保鲜期的效果。
申请号为 200420047891.8 的发明专利涉及一种改良的冰柜保鲜结构，其是在冰柜内安装设有一气体分离膜装置，该气体分离膜装置是具有高分子半透膜，该气体分离膜装置并连接设有一泵及一排放管，使冰柜内部透过该气体分离膜装置所产生的氧气成分，经由排放管被强制排出于冰柜外。借由在冰柜内安装设有气体分离膜装置，将冰柜内部氧气与氮气分离后让氧气排出于冰柜外，使冰柜内氮气成分增加，达成冰柜充填惰性气体，令冰柜除具有良好保存食品功能外，亦具有氮气增加功能，可有效提供更佳保存食物的质量。
申请号为 201210411582.3 的专利涉及一种保鲜冰柜的保鲜气体循环利用方法。保鲜冰柜包括若干用于储藏需保鲜食品的储物室、用于向该储物室提供保鲜气体的氮氧分离装置、与该氮氧分离装置出气口连通的真空泵，开启真空泵，该储物室内含有臭气、有机气体的富氧气体经气体配送器进入该臭气及有机气体脱离装置，经除湿、脱离臭气及有机气体后，再经压缩泵压入氮氧分离装置，经氮氧分离装置分离后的富氮保鲜气体经气体配送器进入储物室内，使储物室内的食物处于富氮气保鲜环境中。本发明具有延长保鲜时间，提高保鲜品质，降低能源消耗，减少食品的交叉污染等优点。
申请号为 200610032834.6 的专利公开了一种带制氮保鲜功能的冰柜、冰柜，其特征在于：所述的带制氮保鲜功能的冰柜、冰柜附设有微型 PSA( 变压吸附 ) 制氮机。采用碳分子筛对氧和氮吸附量的差别这一特性，通过 MCU( 微处理器 ) 或 PLC( 逻辑控制电路 ) 自动控制加压吸附，常压解析的循环过程，富集所需高纯度的氮气，并可根据不同的要求，通过冰柜、冰柜上的控制面板设置并控制制氮机的工作状态和室内的氮气浓度，具有一般冰柜、冰柜的强力冷藏功能之外，又能利用氮气保鲜食物，尤其是疏菜、水果类，实用又方便，让使用者吃得到新鲜食物，是家庭、食品商业店、餐饮业以及公共娱乐场所等食物保鲜的理想产品。
以上专利均是针对整个冰柜提出的氮气保鲜功能，对于冰柜整体实现氮气保鲜功能，存在以下缺点： 1 ）密闭性无法完全保证，由于氮气保鲜技术的本质是提高氮气组分浓度，降低氧气、二氧化碳、乙烯等组分浓度的气调保鲜技术，如果无法保证容器密闭性，外界气体会不断与容器内部气体交换。而密闭仅仅依靠冰柜门封的磁铁是不行的（只能是相对密闭），并且，冰柜间室均会设置用于排水孔（用于排出化霜水），这些管道是外界环境连通的，所以，无法从根本上保证氮气保鲜效果； 2 ）成本增加较多，需要增加较大型的气体分离装置、泵等器件； 3 ）没有考虑内外压差的问题，因为气体经过分离或交换后，会导致箱体内部的压力不等于常压，因此，开冰柜门需要考虑压力平衡的问题； 4 ）对用户使用造成较大影响，实现氮气保鲜需要启动抽气泵对冰柜进行抽气，由于箱体容积较大，所需抽气时间较长，所以会使冰柜的能耗、噪声变大。
发明内容
本发明旨在不改变现有冰柜基本结构的情况下，提供一种有效提高保鲜能力、结构简单、使用便利、成本较低的氮气保鲜抽屉，增加冰柜功能卖点。
为解决上述技术问题，本发明采用的技术方案是：
一种氮气保鲜抽屉，包括抽屉腔体、抽屉盖部件、设置在抽屉腔体的进气口和抽气口、以及抽气装置，所述抽气装置的抽气端与所述抽气口管道连接，在抽屉腔体上设置有气体分离装置，所述气体分离装置的送气端与所述进气口管道连接，气体分离装置的入气端与抽气装置的出气端管道连接， 在抽屉腔体上设置气体分离装置，并使气体分离装置与抽气装置配合一体化地安装在抽屉腔体上，如此结构更加简单 ，在所述抽屉盖部件上设置有泄压部件， 在打开抽屉腔体前回复压力平衡，如此结构更加简单易用 ，在抽屉腔体与抽屉盖部件之间设置有锁紧组件， 可确保抽屉盖部件锁紧在抽屉腔体上，简单而有效地加强保鲜抽屉内部的密封效果。
优选地，气体分离装置上还设置有出气管， 氧气等透过率较快的气体由气体分离装置的出气管排出。
优选地，所述抽气口在垂直方向上低于所述进气口的高度， 由于氮气比空气略轻，抽气口在垂直方向上低于所述进气口的高度，以使进入抽屉腔体的氮气可以停留在上层，下层的空气可以继续通过抽气口排出，如此设置更有利于保证抽屉腔体内的氮气处于较高的含量。
进一步地，所述抽屉盖部件包括盖体、与盖体固定连接的抽屉盖罩、安装在盖体外侧的拉手座、连接于盖体与拉手座的扭簧，以使拉手座能在打开的同时并具备自动复位功能。
进一步地，所述泄压部件包括密封塞、密封塞固定座以及泄压孔，所述泄压孔开设在抽屉盖部件上并连通所述抽屉腔体内腔，所述密封塞固定座与固定在抽屉盖部件上，所述密封塞一端连接于密封塞固定座，另一端配合对应所述泄压孔。
当抽屉盖部件 打开时，密封塞离开泄压孔，以使外界空气能够进入抽屉腔体内，恢复腔体内的气压平衡，使用户可以轻易打开抽屉盖部件。
进一步地，所述锁紧组件包括控制块、连接于控制块的控制杆、连接于控制杆末端的定位轮，以及固定在抽屉盖部件一侧的安装座，所述控制杆通过螺钉可转动地安装在安装座上，所述抽屉腔体对应锁紧组件的一侧设置有锁固定座，所述锁固定座配合锁定所述定位轮。 当控制块往下方位置移动时，控制杆带动定位轮往上方移动，直至定位轮卡合在锁固定座内，以使抽屉盖部件与抽屉腔体紧密闭合，反之，当控制块往上方位置移动，可令控制杆带动定位轮向下移动并离开锁固定座，对抽屉盖部件解锁。
可选地，所述抽屉盖部件在对应锁控制杆的位置开设有导槽，导槽能够让控制杆上下移动并限制控制杆的移动范围。
优选地，所述抽屉盖部件与抽屉腔体之间设置有密封圈，密封圈用于加强保鲜抽屉的密封性。
进一步地，所述气体分离装置内部设置有可收集氮气高分子薄膜， 利用高分子气体膜分离技术可以对空气中的气体组分进行分离，薄膜为天然或人工合成的高分子薄膜，对某些气体组分具有选择性渗透和扩散的特性，可以达到气体分离的目的（通常，渗透率快的水蒸气、氧气等一些气体先透过膜，成为富氧气体，而渗透较慢的氮气则滞留富集，成为富氮气体）。
可选地，所述抽屉盖部件与抽屉腔体的一侧设置有门铰部件，所述门铰部件包括支撑架、门绞，所述支撑架连接所述抽屉腔体的一侧，所述门绞连接支撑架与抽屉盖部件，抽屉盖部件可以围绕门铰部件转动并打开和闭合抽屉腔体。
可选地，在所述抽屉腔体的一侧设置有安装平台，所述气体分离装置和抽气装置安装固定在所述安装平台上，所述气体分离装置通过固定块固定连接在所述安装平台和抽屉腔体之间。
可选地，其特征在于，所述抽屉腔体上靠近抽屉盖部件的位置设置有加强铁，当启动抽气装置以后，抽屉腔体内部的气体流向气体分离装置，由于气体分离装置通过自身的分离作用把其中一部分的气体（氧气、二氧化碳等）分离出去，使抽屉腔体内部的气压低于外界气压，形成负压，这种负压最终使抽屉腔体弯曲变形，加强铁具有加强抽屉腔体的抗变形能力，抵抗这种气压差造成的变形，具有防止抽屉腔体因弯曲变形而损坏的功能。
与现有技术相比，本发明的有益效果是：
将 氮气保鲜抽屉 独立设置，即使安装在冰柜内部，对原有冰柜的内部结构也没有的影响，箱内只需要增加一个电源端子与抽气部件连接，提供电源，冰柜控制面板增加一个按键（控制给抽气部件供电）即可对保鲜抽屉实现控制。在抽屉腔体上设置气体分离装置，并使气体分离装置与抽气装置配合一体化地安装在抽屉腔体上，如此结构更加简单，降低生产成本，并易于产品化。在抽屉盖部件上设置泄压部件，在打开抽屉腔体前回复压力平衡，如此结构更加简单易用，在抽屉腔体与抽屉盖部件之间设置有锁紧组件，可确保抽屉盖部件锁紧在抽屉腔体上，简单而有效地加强保鲜抽屉内部的密封效果。

如图 1~4 所示，一种氮气保鲜抽屉，包括抽屉腔体 1 ，抽屉腔体 1 可拆卸地独立设置在冰柜（图中未画出）内部， 对原有冰柜的内部结构也没有的影响，柜内只需要增加一个电源端子与抽气部件连接，提供电源，冰柜控制面板增加一个按键（控制给抽气部件供电）即可对保鲜抽屉实现控制 ，抽屉腔体 1 后侧开设有抽气口 3 和进气口 4 ，由于氮气比空气略轻，抽气口 4 在垂直方向上低于所述进气口 3 的高度，以使进入抽屉腔体 1 的氮气可以停留在上层，下层的空气可以继续通过抽气口 3 排出，如此设置更有利于保证抽屉腔体 1 内的氮气处于较高的含量，在抽屉腔体 1 后侧还设置有抽气装置 5 和气体分离装置 6 ，抽气装置 5 的抽气端与所述抽气口 4 管道连接，气体分离装置 6 的送气端与所述进气口 3 管道连接，气体分离装置 6 的入气端与抽气装置 5 的出气端管道连接，气体分离装置 6 上还设置有出气管 61 ，并且，气体分离装置 6 内部设置有可收集氮气高分子薄膜（图中未画出），利用高分子气体膜分离技术可以对空气中的气体组分进行分离，薄膜为天然或人工合成的高分子薄膜，对某些气体组分具有选择性渗透和扩散的特性，可以达到气体分离的目的（通常，渗透率快的水蒸气、氧气等一些气体先透过膜，成为富氧气体，而渗透较慢的氮气则滞留富集，成为富氮气体）。在抽屉腔体 1 的后则设置有一安装平台 102 ，气体分离装置 6 和抽气装置 5 安装固定在所述平台 102 上，另外，所述气体分离装置 6 通过一固定块 103 固定连接在安装平台 102 与抽屉腔体 1 之间，另外，在抽屉腔体 1 的一侧设置有一锁固定座 11 ，锁固定座 11 与抽屉腔体 1 一体成型。
在抽屉腔体 1 的开口端连接有一抽屉盖部件 2 ，抽屉盖部件 2 的一侧通过一门铰部件 9 与抽屉腔体 1 的一侧铰接，门铰部件 9 包括支撑架 91 和门绞 92 ，支撑架 91 固定安装在抽屉腔体 1 的一侧，门铰 92 安装在支撑架 91 上并同时连接抽屉盖部件 2 ，以使抽屉盖部件 2 可以绕门铰部件 9 转动并且打开和关闭抽屉腔体 1 ，此外，抽屉盖部件 2 与抽屉腔体 1 之间设置有一密封圈 101 ，密封圈形状和大小与抽屉腔体 1 的开口相仿，密封圈 101 安装在抽屉盖部件 2 的后侧，以使抽屉盖部件 2 关闭后，可以密封抽屉腔体 1 内部。抽屉盖部件 2 包括盖体 21 、抽屉盖罩 22 、拉手座 23 、的扭簧 24 、泄压孔 25 ，盖体 21 后侧对应抽屉腔体 1 的开口，门铰部件 9 设置在盖体 21 上，抽屉盖罩 22 连接于盖体 21 前侧，拉手座 23 设置在抽屉盖体 21 与抽屉盖罩 22 之间，并且位于抽屉盖本体 21 的中部位置，扭簧 24 安装连接于拉手座 23 底部，并且同时与抽屉盖体 21 连接，使拉手座 23 能在打开的同时并具备自动复位功能，在盖体 21 上对应拉手座 23 的位置开设有所述的泄压孔 25 ，泄压孔 25 连通抽屉腔体 1 与外界空气。在拉手座 23 后侧安装有一泄压部件 7 ，泄压部件 7 包括密封塞 71 、密封塞固定座 72 ，密封塞固定座 72 与拉手座 23 后侧固定连接，密封塞 71 一端连接于密封塞固定座 72 ，另一端配合对应所述泄压孔 25 ，当拉手座 23 关闭时，密封塞 71 封闭泄压孔 25 ，当拉手座 23 打开时，密封塞 71 离开泄压孔 25 ，以使外界空气能够进入抽屉腔体 1 内，恢复腔体内的气压平衡。在抽屉腔体 1 与抽屉盖部件 2 之间的一侧设置有一锁紧组件 8 ，锁紧组件 8 包括控制块 81 、控制杆 82 、定位轮 83 、安装座 84 ，安装座 84 通过螺丝固定连接在盖体 21 的一侧，控制杆 82 的非端部位置铰接于安装座 84 内侧，定位轮 83 连接于控制杆 82 靠近抽屉腔体 1 的一端，在抽屉腔体 1 对应锁紧组件 8 的一侧设置有一锁固定座 11 ，锁固定座 11 与抽屉腔体 1 一体成型，锁固定座 11 可配合并锁定定位轮 83 ，抽屉盖部件 2 的抽屉盖罩 22 在对应控制杆 82 的位置开设有导槽 100 ，控制杆 82 远离抽屉腔体 1 的一端穿过导槽 100 后连接所述控制块 81 ，控制块 81 可带动控制杆 82 绕铰链上下运动，当控制块 81 往下方位置移动时，控制杆 82 带动定位轮 83 往上方移动，直至定位轮 83 卡合在锁固定座 11 内，以使抽屉盖部件 2 与抽屉腔体 1 紧密闭合，反之，当控制块 81 往上方位置移动，可令控制杆 82 带动定位轮 83 向下移动并离开锁固定座 11 ，对抽屉盖部件 2 解锁。另外，在抽屉腔体 1 顶面靠近抽屉盖部件 2 的位置设置有加强铁 1 2 ，加强铁 12 与锁固定座 11 以及抽屉腔体 1 一体成型，当启动抽气装置 5 以后，抽屉腔体 1 内部的气体流向气体分离装置 6 ，由于气体分离装置 6 通过自身的分离作用把其中一部分的气体（氧气、二氧化碳等）分离出去，使抽屉腔体 1 内部的气压低于外界气压，形成负压，这种负压最终使抽屉腔体 1 弯曲变形，加强铁 12 具有加强抽屉腔体 1 的抗变形能力，抵抗这种气压差造成的变形，具有防止抽屉腔体 1 因弯曲变形而损坏的功能。
当用户使用冰柜的氮气保鲜抽屉时，先关上抽屉盖部件 2 ，并拉下锁紧部件 8 ，使抽屉腔体 1 处于密闭状态，然后通过按下冰柜控制面板上的按键 ( 图中未画出 ) ，给抽气装置 5 供电，启动抽气装置 5 ，抽屉腔体 1 内的空气就会通过连接管道从抽气口 4 进入抽气装置 5 ，再通过管道送至气体分离装置 6 ，氧气等透过率较快的气体由气体分离装置 6 的出气管 61 排出，氮气则通过气体分离装置 6 ，经由进气口 3 进入到抽屉腔体 1 中，如此循环多次，使抽屉腔体 1 中的氮气浓度不断提高，当抽屉腔体 1 中的气压达到一定的真空度（ 0.5-0.7 个大气压）或者抽气装置 5 的抽气时间达到一定的时间（最长不超过 3 分钟，以 1.5 分钟 -2 分钟为宜），抽气装置 5 自动停止运行。由于抽屉腔体 1 内部某些组分的气体被抽出，导致抽屉腔体 1 内部气压低于外部气压，形成负压。当用户需要取出氮气保鲜抽屉中的食物时，需要做泄压处理后才能比较容易打开抽屉盖部件 2 。此时，用户可以通过向外拉动抽屉盖部件 2 中间的拉手座 23 ，带动密封塞 71 脱离抽屉腔体 1 上的泄压孔 25 ，从而使外部空气通过泄压孔 25 迅速回流到抽屉内部，使腔体内外气压平衡。当气压平衡后，松开的拉手座 23 ，拉手座 23 由于扭簧 24 的预紧力而重新复位，使泄压部件 7 的密封塞 71 密封泄压孔 25 。此时，再将锁紧部件 8 向上拉带动控制杆 82 ，并使得定位轮 83 离开锁固定座 11 ，使抽屉盖部件 2 得以打开，完成泄压和解锁动作。当用户取出所需的食品后，可以再度关上抽屉盖部件 2 ，并拉下锁紧部件 8 ，使抽屉腔体 1 重新处于密闭状态。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动，这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
