如图1至图5所示，本发明的冰箱100，包括箱体1、门体2、设置在箱体1内的抽屉组件3、主控板(未图示)及显示控制板4，所述显示控制板4设置在所述门体2上，所述主控板与所述显示控制板4电性连接。
所述箱体1具有储物空间11和位于所述储物空间11相对两侧的两个侧壁12，两个所述侧壁12上均固定设有第一滑轨13和第二滑轨14，所述第一滑轨13设置在所述第二滑轨14的上方。
所述抽屉组件3包括抽屉本体31、盖在所述抽屉本体31上的抽屉盖体32、调节机构33、用以向抽屉本体31内部加湿的加湿模块34和用以检测所述抽屉本体31内部湿度的湿度传感器35。所述抽屉盖体32至少具有与所述抽屉本体31紧密配合的第一状态、位置升高使得所述抽屉本体31与外部进行空气交换的第二状态，所述调节机构33用以调节所述抽屉盖体32在第一状态和第二状态之间进行切换。
所述抽屉本体31和抽屉盖体32设置在两个所述侧壁12之间，所述抽屉盖体32设置在第一滑轨13之间，所述抽屉本体31设置在第二滑轨14之间。所述抽屉本体31可以在所述第二滑轨14上前后滑动，所述抽屉盖体32可以在所述第一滑轨13上前后滑动。
所述抽屉本体31在与所述抽屉盖体32两侧的配合处设有第一凸起311，所述第一凸起311靠近所述抽屉本体31前端。所述抽屉盖体32上设有用以与所述第一凸起311配合的第一配合槽321，所述第一凸起311与所述第一配合槽321配合以使得在向外拉动抽屉本体31时，带动所述抽屉盖体32一起向外运动。
所述抽屉盖体32上设有边缘向外延伸形成一对第二凸起322和一对第三凸起323，所述第二凸起322靠近抽屉盖体32前端设置，所述第三凸起323靠近所述抽屉盖体32后端设置。所述第一滑轨13上设有与所述第二凸起322和第三凸起323配合的第一滑动槽131和第二滑动槽132，所述第一滑动槽131和第二滑动槽132均具有前壁1311、后壁1312和底壁1313，所述第一滑动槽131的底壁1313倾斜设置，且自后向前先逐渐升高，再水平设置。所述第二动滑槽132的底壁1313中部设有一个抵挡结构1321。
当所述抽屉盖体32处于第一状态，且未抽出抽屉本体31时，所述第二凸起322与所述第一滑动槽131的后壁1312和底壁1313相抵接，即所述第二凸起322位于所述第一滑动槽131的最低点。
向外拉动抽屉本体31，所述抽屉本体31带动所述抽屉盖体32向外运动，所述第二凸 起322和所述第三凸起323分别在第一滑动槽131和第二滑动槽132内向前滑动，由于所述第一滑动槽131的底壁1313自后向前逐渐升高，故所述抽屉盖体32的位置也逐渐升高。当所述第二凸起322滑动至所述底壁1313水平的位置，且所述抽屉盖体32提高到所述第一配合槽321脱离所述第一凸起311，此时所述抽屉盖体32不再移动，所述抽屉本体31可正常拉出。所述第二滑动槽132的抵挡结构1321防止此时所述抽屉盖体32在重力作用下滑落。
向内推动所述抽屉本体31，直到所述抽屉本体31与所述抽屉盖体32的后端配合处相接触时，所述抽屉本体31带动所述抽屉盖体32慢慢下滑，直至所述第一凸起311和第一配合槽321相配合，此时恢复所述抽屉盖体32的第一状态，所述抽屉本体31和所述抽屉盖体32紧密配合。
在抽屉本体31和抽屉盖体32上设置上述结构，防止了抽屉本体31和抽屉盖体32之间的配合处长期摩擦造成的密封不严的情况，且拉出和推进所述抽屉本体31时十分省力。
所述加湿模块34用以向所述抽屉本体31内加湿，在所述抽屉本体31与所述抽屉盖体32紧密配合时，所述加湿模块34可以使得所述抽屉本体31内的湿度达到90％。所述湿度传感器35用以检测所述抽屉本体31内部湿度，并将检测结果传送给主控板。
所述调节机构33包括电机331、连接所述电机331并与所述抽屉盖体32相配合的凸轮333。
所述电机331和所述冰箱100的主控板电性连接，所述主控板可以在接收到指令后控制所述电机331的启动。
本实施方式的电机331为步进电机，并包括有电机轴332，且所述步进电机每步进32步，所述电机轴332转动90°。所述电机331设置在所述第一滑轨13的外侧，并与所述第一滑轨13固定连接。
所述凸轮333包括轮体334、设置在轮体334一侧的转轴335、设置在轮体334另一侧的凸轮轴336。所述转轴335与所述凸轮轴336在轮体334径向间隔设置。使得所述凸轮轴336具有最低位置和高于最低位置的其他位置，所述电机331启动使得所述凸轮轴336在最低位置与其他位置间进行切换，当所述凸轮轴336处于最低位置时，所述抽屉盖体32处于第一状态，当所述凸轮轴336切换至其他位置时，所述凸轮轴336带动所述抽屉盖体32升高，使得所述抽屉盖体32处于第二状态。本实施方式的轮体334为圆形，所述转轴335设置在所述轮体334的中央，所述转轴335靠近所述轮体334的边缘设置。
所述第一滑轨13上设有与所述轮体334相适应的凹槽133，所述转轴335向外突伸，并与所述电机轴332固定连接。所述抽屉盖体32侧边向外开设有收容槽324，所述凸轮轴336向抽屉盖体32方向突伸入所述收容槽324，并与围成所述收容槽324的顶壁相抵接。所述收容槽324呈长条状，且沿所述抽屉盖体32前后方向延伸，所述凸轮轴336与收容槽324相配合，以使得向外拉动抽屉本体31过程中，收容槽324可相对于凸轮轴336滑动，从而使得所述抽屉盖体32可向外移动。
所述显示控制板4包括显示部41和控制按钮42，所述显示部41显示有所述抽屉本体31内的湿度值。本实施方式的冰箱100设有三个控制按钮42，分别对应高湿、中湿和低湿。
当需求湿度较高时，按下高湿控制按钮42，此时电机331控制所述凸轮333转动，使得所述凸轮轴336处于最低位置，所述抽屉本体31和所述抽屉盖体32紧密配合，所述抽屉本体31内的湿度可以达到90％，适合存放蔬菜。
当需求湿度适中时，按下中湿控制按钮42，此时所述电机331控制所述凸轮333转动，所述凸轮轴336旋转至与最低位置相差90°，所述凸轮轴336将所述抽屉盖体32顶高4MM，所述抽屉本体31内的湿度可达85％，适合存放水果。
当需求湿度较低时，按下低湿控制按钮42，此时所述电机331控制所述凸轮333转动，所述凸轮轴336旋转至与最低位置相差180°，所述凸轮轴336将所述抽屉盖体32顶高8MM，所述抽屉本体31内的湿度可达70％，适合存放牛奶、鸡蛋等。
所述冰箱100也可以设置自主控制按钮42，用户可以根据需要选择任意湿度，且所述湿度传感器35对所述抽屉本体31内的湿度进行监控，一端时间后湿度未达到设定值，所述电机331自动启动，改变凸轮轴336的位置，使湿度达到设定值。
由于电机331多次转动可能会产生误差，本发明还提供了如下控制方法：主控板接收到电机331驱动指令后，判断电机331累计步进步数S＇是否大于冰箱100设定的复位步数S；
如果S＇大于S，则对电机331进行复位，此时所述抽屉盖体32处于第一状态，然后根据指令计算电机331需要步进的步数；
如果S＇小于等于S，判断抽屉盖体32所处状态，并根据抽屉盖体32的状态和指令计算电机331需要步进的步数；
根据计算结果驱动电机331运行。
本实施方式中，所述S为1000步，即所述电机331步进超过1000步，进行一次复位，如此减少了产生误差的可能性。
本发明的抽屉组件3、具有该抽屉组件3的冰箱100及该冰箱100的控制方法，通过设置电机331、与电机331和所述抽屉盖体32连接的凸轮333，从而可以通过转动电机331控制所述抽屉盖体32的高度，从而达到调节所述抽屉本体31内部湿度的目的；通过在所述抽屉盖体32上设置第二凸起322和第三凸起323，而在所述第一滑轨13上设置与所述第二凸起322和第三凸起323配合的第一滑动槽131和第二滑动槽132，从而使得所述抽屉本体31拉出、推进都省力，且不会造成抽屉本体31和抽屉盖体32之间因摩擦过大引起配合处磨损的问题；通过累计步数判断的控制方法，减少了产生误差的可能。
以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围。
