一种保鲜密封装置及冰箱
技术领域
本发明涉及制冷技术领域，更具体地，涉及一种保鲜密封装置及装配有该保鲜密封装置的冰箱 。
背景技术
冰箱内，采用抽屉分装食物，不同的食物为了维持其最佳新鲜度而需要不同的湿度，现有技术中，通常在抽屉的前端或盖子上开孔，但采用这种办法，抽屉内不能保持密封或高效导出湿气，导致抽屉内食物很快干枯或因聚集冷凝水腐烂变质，这样食物的新鲜程度及存储稳定性将严重受损，所以需要根据抽屉内的食物类型从抽屉内导出湿气，调整抽屉内的湿度，达到存储物保鲜。然而，在已知技术中，这种湿度的调节效率是极低的。因此，有需要寻求一种能实现湿度的高效的调节的装置。
发明内容
本发明要解决的技术问题是针对现有技术的不足而 提供一种 能实现高效的湿度调节的 保鲜密封装置。
本发明还提供一种装配有该保鲜密封装置的冰箱。
为解决上述技术问题，本发明第一方面的技术方案如下：
一种保鲜密封装置，包括抽屉及设在抽屉上方、且与抽屉匹配的盖体、设于盖体上方的层架，所述盖体悬置于层架下方，所述抽屉的顶面与盖体的底面均设置为从 前往后向下倾斜 的平面，通过盖体的 前后水 平运动，实现抽屉的密封或打开。
进一步的，所述盖体和层架前侧相应位置上设有调节盖体前后水平运动的调节装置。
更进一步的，所述层架前侧边缘为水平引导轮廓，所述盖体前侧设有盖引导柱或盖斜角引导轮廓；所述调节装置包括调节块和滑块，所述调节块设有筋，所述滑块上设有供筋插入的孔，设有与盖引导柱或盖斜角引导轮廓相配合的滑块斜角引导轮廓或滑块引导柱，通过筋插入孔和盖引导柱插入滑块斜角引导轮廓或滑块引导柱插入盖斜角引导轮廓，调节块、层架、滑块和盖体的位置依次从上到下叠放，通过调节块在水平引导轮廓上左右移动实现盖体的 前后水 平运动。
更进一步的，所述滑块斜角引导轮廓为 2 个，分别设于滑块的左右端部。这样引导盖体 前后水 平运动的平衡性更好。
更进一步的，所述盖体左右两侧设有盖引导机构，所述层架左右两侧相应设有与盖引导机构配合的层架引导机构。
更进一步的，上述保鲜密封装置还包括紧固件，所述调节块和滑块通过紧固件固定在一起。防止调节块和滑块相对转动。
更进一步的，所述抽屉两侧设有导轨，通过导轨安装在层架的侧面。
综上，调节块在层架上的水平引导轮廓运动，牵引滑块运动，通过滑块上的滑块斜角引导轮廓及盖体上的盖引导柱传递，或者通过滑块上的滑块引导柱及盖体上的盖斜角引导轮廓传递，使盖体可以前后运动，同时盖体上的盖引导机构插入层架上的层架引导机构内，引导盖体沿层架引导机构前后水平可滑动。最终，通过盖体的前后水平运动，实现抽屉的密封或打开。
本发明第二方面的技术方案如下：
一种冰箱，包括冷藏室，冷藏室的内壁上设有多个通风孔，所述冷藏室内装配有上述的保鲜密封装置，所述通风孔至少有一个低于盖体的位置。
优选的，所述 冷藏室的侧壁设有凸起，所述层架两侧固定在凸起上。
更优选的，所述 凸起设有止挡槽，所述层架两侧设有止挡卡扣，通过止挡卡扣卡进凸起的止挡槽固定所述 保鲜密封装 置。
与现有技术相比，本发明技术方案的有益效果是：
1 、本发明保鲜密封装置通过盖体的 滑动，可以调整打开的通气间隙的大小，以满足不同存储物的需要， 盖体相对于抽屉在 任何位置停止都是稳定的，即 盖体 具有自锁功能。
2 、 当抽屉处于打开位置时，抽屉外的空气和抽屉内空气形成循环交换，达到抽屉内外空气快速交换 。

具体实施方式
下面结合附图详细描述本发明的实施例，附图中自始至终相同或相类似的标号标示相同或相类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。
实施例 1 ：
如图 1 、图 2 中，本发明公开一种保鲜密封装置，包括层架 1 、盖体 2 和抽屉 3 ，盖体 2 与抽屉 3 匹配，设在抽屉 3 上方，层架 1 设在盖体 2 上方，抽屉 3 的顶面 31 与盖体 2 的底面 24 均设计为从前往后向下倾斜的平面，盖体 2 的倾角和抽屉 3 的顶面 31 的倾角是一致的。通过盖体 2 的前后水平运动，实现抽屉 3 的密封或打开。
为实现盖体 2 的前后水平运动，在盖体 2 和层架 1 前侧相应位置上设有调节装置，层架 1 前侧边缘设计为水平引导轮廓 11 ，盖体 2 前侧设有盖引导柱 22 ，调节装置包括调节块 12 和滑块 21 ，调节块 12 设有筋 121 ，滑块 21 上设有供筋 121 插入的孔 211 ，且设有与盖引导柱 22 相配合的滑块斜角引导轮廓 212 ，通过筋 121 插入孔 211 和盖引导柱 22 插入滑块斜角引导轮廓 212 ，调节块 12 、层架 1 、滑块 21 和盖体 2 的位置依次从上到下叠放，通过调节块 12 在水平引导轮廓 11 上左右移动实现盖体 2 的 前后水 平运动。
当然，盖体 2 的盖引导柱 22 处可以设计为盖斜角引导轮廓，相应地滑块 21 的滑块斜角引导轮廓 212 设计为滑块引导柱，通过滑块引导柱插入盖斜角引导轮廓可以实现与盖引导柱 22 插入滑块斜角引导轮廓 212 相同的作用。盖斜角引导轮廓和滑块引导柱图中未示。
图中，滑块斜角引导轮廓为 2 个，分别设于滑块 21 的左右端部。这样引导盖体 2 前后水 平运动的平衡性更好。 另外盖体 2 左右两侧设有盖引导机构 23 ，层架 1 左右两侧相应设有与盖引导机构 23 配合的层架引导机构 13 。
上述保鲜密封装置还设有紧固件 4 ， 调节块 12 和滑块 21 通过紧固件 4 固定在一起。以防止调节块 12 和滑块 21 相对转动。
调节块 12 经在层架 1 上的水平引导轮廓 11 运动，牵引滑块 21 运动，通过滑块 21 上的滑块斜角引导轮廓 212 及盖体 2 上的盖引导柱 22 传递，盖体 2 可以前后运动，同时盖体 2 上的盖引导机构 23 插入层架 1 上的层架引导机构 13 内，引导盖体 2 沿层架引导机构 13 前后水平可滑动。
当调节块 12 如图 2 所示向左边位置滑动时，盖体 2 将向前滑动，当调节块 12 完全滑动到左边后，盖体 2 将滑动到抽屉 3 的上边，此时盖体 2 的底面 24 和抽屉的顶面 31 四周是完全接触的，实现了密封，密封示意图如图 3 所示。
当调节块 12 如图 2 所示向右边位置滑动时，盖体 2 将向后滑动，在此运动过程中，盖体 2 上的盖引导机构 23 沿层架 1 上的层架引导机构 13 运动，盖体 2 是水平运动的，故盖体 2 向后运动后会很快脱离底部抽屉 3 的顶面 31 ，使抽屉 3 和盖体 2 前后错层而形成间隙，盖体 2 向后滑动越多，间隙越大，间隙的大小可实现不同抽屉 3 内的湿度调节。 打开的示意 图如图 4 所示。
盖体 2 滑动打开的通气间隙大小可以根据不同存储物进行选择调整，盖体 2 在任何停止位置是稳定的，具有自锁功能。
通常盖体 2 由塑料注塑而成，由平坦或弓形的中部和周边加强筋构成。
当抽屉 3 和盖体 2 在关闭状态时，盖体 2 的底面 24 和抽屉 3 的顶面 31 四周是完全接触并密封的；当抽屉 3 向外拉出时，因倾角的作用，抽屉 3 短距离的移动将会使盖体 2 和抽屉 3 分离，盖体 2 下落后盖引导机构 23 悬挂在层架引导机构 13 上，避免盖体 2 和抽屉 3 较长距离的摩擦。
层架 1 由安全玻璃 14 和塑件 15 （或金属型材）制作而成，水平向内延伸的层架引导机构 13 设置在塑件 15 的下方，盖体 2 上的盖引导机构 23 插入层架 1 的层架引导机构 13 内，引导盖体 2 沿层架引导机构 13 前后滑动。
实施例 2 ：
如图 3 、图 4 中，本发明还公开一种装配有上述保鲜密封装置的冰箱，该冰箱包括门体 6 、箱体 7 、冷藏室 5 以及装配在冷藏室 5 内的风扇 8 、蒸发器 9 、盖板 10 、压缩机及管件（图未示出）等，盖板 10 上开设有多个通风孔 101 。上述保鲜密封装置安装在冷藏室 5 内，同时有通风孔 101 处于低于盖体 2 的位置上。而抽屉 3 可以安装在冷藏室 5 的侧壁上，也可以通过导轨（图未示出）安装在层架 1 的侧面上。
具体的， 冷藏室5的侧壁设有凸起51， 上述保鲜密封装置通过层架 1 的两侧底面 17 安装在冷藏室 5 侧壁的 凸起51 上，而且 凸起51设有止挡槽 （图未示出） ，层架1的两侧相应设有止挡卡扣16，通过止挡卡扣16卡进凸起51的止挡槽固定， 使层架 1 稳固，不会前后窜动。
图 3 示意了保鲜密封装置在关闭密封位置状态，冷空气经由通风孔 101 ，通过盖体 2 和层架 1 之间的间隙至抽屉 3 的前端流出，和冷藏室 5 及制冷循环系统形成空气循环，该状态下，循环的冷空气将从保鲜密封装置四周对其进行冷却，保证冷却均匀且快速，避免局部冷却而聚集冷却水，同时该保鲜密封装置由抽屉 3 和盖体 2 形成密封空间，防止湿气挥发，有效保证恒定的低温恒湿的环境，适于抽屉 3 内存储物保鲜存储。
图 4 为保鲜密封装置的盖体 2 滑开后进行湿度调节状态的示意剖视图。此时盖体 2 和抽屉 3 至少在前后位置有通气间隙，冷空气经通风孔 101 ，通过盖体 2 和抽屉 3 的前后间隙流通，和冷藏室 5 及制冷循环系统形成空气循环，该状态下，流动的循环冷空气可导出保鲜密封装置中的多余湿气，同时可使抽屉 3 内存储物快速冷却，实现适宜的存储环境，达到保鲜效果。
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。
