Description

用于冰箱的保鲜箱 技术领域
本发明涉及一种用于冰箱的保鲜箱。
背景技术
在冷藏过程中，空气中的水分含量对食品的耐藏性有直接的影响。一般情况下，空气不易过干也不易过湿，因为低温的食品表面和高湿度的空气相遇，就会有水分冷凝在其表面(果蔬的发汗现象)，冷凝水过多，食品容易引发发霉和腐烂现象；同时，湿度过低，食品中的水分会迅速蒸发并出现萎缩(细胞的膨压降低，导致萎缩现象)。对于果蔬来说，会影响柔韧性和抗病性。活细胞的枯萎还会引起细胞内酶性反应改向，即合成减弱，分解加强。此外，水分蒸发会使果蔬的重量和维生素含量大量损耗，耐藏性变差，因此贮藏室内的空气湿度对食品的保存期限十分重要。
现有技术公开了一种高湿度保鲜冰箱，在冷藏室内设置调湿材料，当冷藏室内湿度过高时，材料吸湿，当室内温度过低时，材料释放水分增湿。现有技术还公开了一种冰箱用湿度补偿器及保湿冰箱，是在冷藏室内置一储水装置和一吸水装置，吸水装置吸收水分后再释放到冷藏室，以保持冷藏室的湿度。上述结构和方法虽能在一定程度上保持冷藏室湿度稳定，但不能针对不同储藏物将湿度调节至适宜程度，即现有技术仅能增湿或保湿，但无法调湿。

参见图3和图4，板框21包括相对设置的前边框211和后边框212、及相对设置的两个侧边框213。前边框211具有相对设置的前端壁2111和后端壁2112。前边框211上内凹形成有收纳槽214，收纳槽214贯穿前边框211的前端壁2111以形成按钮孔2141，收纳槽214贯穿前边框211的后端壁2112以形成安装孔2142。收纳槽214自其底面向上突伸形成有多个定位条2143，定位条2143排列形成一定位狭槽2145。参见图6，在本实施例中， 定位狭槽2145呈曲线形状，其自前边框211的前端壁2111平缓的朝后端壁2112延伸形成。后边框212的底部向下突伸形成有一对凸块2121。每个凸块2121上均开设有插孔2122。每个侧边框213自其外端内凹形成有卡扣槽2131，通过该卡扣槽2131使其与一滑道架200配合，从而固定该板框21(参见图1)。
参见图2至图6，自落板22包括板体221、自板体221的周边向外延伸形成的边沿架222、及位于自落板22的前端且沿保鲜箱100宽度方向上延伸的自落轨道223。板体221于保鲜箱100的宽度方向上的横截面形状呈波浪形。边沿架222包括相对设置的前边沿架2221和后边沿架2222、及相对设置的两个侧边沿架2223。前边沿架2221上形成有导轨槽2224。导轨槽2224位于前边沿架2221的中段(即中间区段)。自落轨道223设置在导轨槽2224内。自落轨道223于保鲜箱100的宽度方向上自其右端朝左端逐渐向下倾斜延伸形成。本领域技术人员可意识到，此处指示相对位置关系的用语“左”、“右”是基于图6的观察方向而言的。于保鲜箱100的高度方向上，自落轨道223突伸出前边沿架2221。自落轨道223的周边形成有护栏2226。护栏2226与前边沿架2221及自落轨道223一体设置。在自落板22与板框21组装后，自落轨道223穿过安装孔2142收纳在收纳槽214内。后边沿架2222后端向后突伸形成有插入至后边框212插孔2122内的插块2225。每个侧边沿架2223上形成有与箱体1的凸缘部16配合的内凹部2227，通过内凹部2227和凸缘部16的配合，从而便于箱体1的抽拉。
参见图2和图3及图6，调节结构23收容在板框21的前边框211的收纳槽214内。调节结构23包括沿保鲜箱100的宽度方向上延伸的片状本体231、及分别设置在片状本体231两端的驱动部232和按钮233。片状本体231收容在定位条2143所形成的定位狭槽2145内，通过该定位狭槽2145从而防止调节结构23在移动的时候，片状本体231前后晃动而影响调节结构23活动顺畅，同时也可防止片状本体231折弯而报废。驱动部232自片状本体231的左端向上突伸形成。驱动部232于保鲜箱100的宽度方向上自左端朝右端逐渐向上倾斜突伸形成。按钮233用以供用户拨动以使调节结构23左右移动。按钮223自片状本体231的右端向前突伸形成。
参见图2至图6，在盖板2组装后，自落板22的板体221设置在板框21内，自落板22的插块2225插入至后边框212插孔2122内，且插块2225 可在插孔2122内活动，自落轨道223穿过安装孔2142收纳在收纳槽214内。调节结构23收容在板框21的前边框211的收纳槽214内，片状本体231位于定位狭槽2145内，按钮223的前端突伸出板框21的按钮孔2141，驱动部232与自落轨道223配合，可相对自落轨道223滑动以使得自落板22抬起或者落下。在本实施例中，由于自落轨道223设置在前边沿架2221上，调节结构23设置在前边框211上，即自落轨道223和驱动部232均设置在盖板2的前端，从而使得用户用很小的力就能使自落板22抬起。玻璃隔板24设置在自落板22上方，并且玻璃隔板24与自落板22之间具有一定间距，从而给自落板22在抬起时一定的活动空间。装饰盖25设置在盖板2的前端，以遮蔽板框21、自落板22和玻璃隔板24的前端。装饰盖25上相对按钮223开设有开口251以便按钮223突伸出。
结合图8至图10，当保鲜箱100内的湿度过高时，用户向左(图9中箭头f所指方向)推动按钮233，使按钮233在按钮孔2141中向左移动，按钮233带动驱动部232向左移动，驱动部232相对自落轨道223向左滑动，此时，自落板22以插块2225为支点，在插孔2122内转动，以使得自落板22向上抬起(自落板22的移动方向为图10中箭头g所指方向)。结合图6和图7，当保鲜箱100内的湿度过低时，用户向右(图6中箭头h所指方向)推动按钮233，使按钮233在按钮孔2141中向右移动，按钮233带动驱动部232向右移动，驱动部232相对自落轨道223向右滑动，自落板22以插块2225为支点，在插孔2122内转动，以使得自落板22落下(自落板22的移动方向为图7中箭头i所指方向)。
除本实施例外，在其他实施例中，自落轨道223和驱动部232可以呈其他形状，如自落轨道223和驱动部232中的任意一个为平板结构；又或者与本实施例中的设置方向相反。
综上所述，该保鲜箱100通过设置自落板22和调节结构23，且自落板22具有沿保鲜箱宽度方向上延伸的自落轨道223，调节结构23具有驱动部232，驱动部232相对自落轨道223滑动以使得自落板22抬起或者落下，从而使得保鲜箱100结构简单，调节更便捷。
尽管为示例目的，已经公开了本发明的优选实施例，但是本领域的普通技术人员将意识到，在不脱离由所附的权利要求书公开的本发明的范围和精神的情况下，各种改进、增加以及取代是可能的。
