具体实施方式
图1和图2示出了本发明的制冷设备的第一实施方式。
如图1和图2所示,整个制冷设备包括内部有收容空间的箱体40，连接在箱体40上并可在开启位置与闭合位置之间转动的门体50，门体50至少部分为透明或者可变透明，采用这种结构是为了当人在制冷设备附近时，人在不开门的情况下即可看清箱体40内的物品。该制冷设备还包括：
微波人感模块20，可以持续发射微波信号并持续接收回波信号，设置于箱体40底部的人感盒60内；
人感盒60采用塑料材质，可以是ABS阻燃材质，其耐燃性和绝缘性较好，人感盒60嵌入式的安装在箱体40的底部并靠近安装有门体50的那一侧面，人感盒60的前部可以全部也可以部分裸露于遮挡板70，采用这种安装方式，能够保证微波人感模块20的正常工作，同时使制冷设备的外观更加美观；
遮挡板70，为U型的板状结构，其两侧边通过螺钉固定在箱体40底部，遮挡板70采用金属材质，可以防火，同时可以防止人或者宠物接触内部电控部件，遮挡板70为栅栏状结构，有利于散热排风，遮挡板70上还开有和人感盒配合的方形孔；
照明模块30，设置于箱体40的内部，可以是安装在箱体40内部的上方，也可以是安装在箱体40内部的后壁或者侧壁，用于箱体40内部空间的照明；
主控模块10，图2中未示出，设置于箱体40的底部，分别与所述微波人感模块20和照明模块30通信连接，并根据微波人感模块20接收到的回波信号来控制照明模块30。
采用这种结构设计，可以实现准确检测并判断人的运动状态，其检测精度不受环境温度的影响，从而使人在不开门的情况下能够看清冰箱内物体的同时节约能源，且人感模块采用嵌入式的安装方式,能够在保证微波人感模块正常工作的同时使制冷设备更加美观。
图3至图7示出了人感盒60的具体结构。
如图3所示，人感盒60包括盒61和盖62。
如图3和图4所示，盒61具有前壁610，自前壁610四周同向延伸形成四个侧壁，包括上侧壁611，下侧壁612，左侧壁613，右侧壁614。
前壁610包括面6102和平行且高于面6102的凸台6101。凸台6101的宽度和微波人感模块20的宽度尺寸相适应，凸台6101前表面和面6102之间的高度差小于等于遮挡板70的厚度。
凸台6101可以置入遮挡板70上设有的方形孔内，从而使前壁610部分外表面裸露于遮挡板70外，防止微波人感模块20发射的微波信号被金属屏蔽。采用这种结构设计，可以使人感盒60嵌入式的安装于箱体40底部，不会突出于遮挡板70，使制冷设备的外观看起来更加美观。
上侧壁611相对于左侧壁613和右侧壁614向外对称延伸出左右两个耳6112，耳6112上设有通孔6111，螺钉经过通孔6111将人感盒60安装在箱体40的底部，采用这种结构设计，便于人感盒60的拆装，且可靠性较高。
右侧壁614中部设有用于线束走线的凸字形走线口6142，方走线口6142的上方和下方远离前壁610的位置设有两个小矩形槽孔6141。
左侧壁613上设有和右侧壁614上的槽孔6141尺寸相同且位置对称的两个槽孔6131。
如图5所示，盖62的左右两端各设有和盒61上的槽孔6131和槽孔6141位置及尺寸相对应的两个小凸起621，盖62可以从盒61的后方通过其上的凸起621卡入盒61上的槽孔6131和槽孔6141内，从而将盖62固定于盒61的后部。
采用这种几乎全密封的结构设计，可以防止虫子爬入或者水溅入人感盒60内，从而造成短路等故障，同时整体结构简单，便于加工制造，也便于盖62的拆装，可靠性也比较高。
如图6所示，盒61内设有挡板615，其上表面和凸台6101的下壁内侧面处于同一平面，其下表面上设有四个加强筋6151。挡板615和上侧壁611共同起到限制微波人感模块20上下移动的作用。
挡板615上表面和上侧壁611的下表面上各设有四个支撑柱616，支撑柱616相接于凸台6101的内表面，用于支撑微波人感模块20，有利于微波人感模块20的散热。
上侧壁611的下表面中部设有限位柱617，限位柱617相接于凸台6101的内表面，其端部可以插入微波人感模块20，用于限制微波人感模块20的左右运动。
凸台6101内表面上，挡板615和上侧壁611的中部位置设有第一卡扣618和第二卡扣619，两个卡扣之间的距离和微波人感模块20的长度尺寸相适应。
如图7所示，第一卡扣618包括第一板6181，两个第一加强筋6182和一个第一卡块6183。第一卡块6183的远离前壁610的表面可以为倾斜面也可以为曲面，靠近前壁610的表面和前壁610的壁面平行，第一板6181突出于第一卡块6183。
第二卡扣619包括第二板6191，两个第二加强筋6192和第二卡块6193，第二卡块6193靠近和远离前壁610的表面均和前壁610的壁面平行。
第一卡块618和第二卡块619共同用于限制微波人感模块20的前后运动。采用这种结构设计，可以使微波人感模块20的安装更加简单、稳固。
如图8，微波人感模块20上侧中部设有槽21。安装时，微波人感模块20从盒60的后方插入挡板615和上侧壁611之间，经过第一卡扣618和第二卡扣619，其左右两端被卡住，表面紧贴支撑柱616，同时限位柱617的端部插入槽21内，限制微波人感模块20的侧向移动。采用这种结构设计，构造简单，可以实现微波人感模块20的稳定固定。
图9和图10示出了本发明的制冷设备的第二实施方式。第二实施方式和第一实施方式的区别在于第二实施方式增加了门开关感应模块80，其余部分和第一实施方式相同，此处不再赘述。
如图10所示，门开关感应模块80包括设置在门体50底部内侧的磁铁81以及设置在箱体底部靠近门体所在侧面的霍尔传感器82，磁铁81可以提供磁场，随着门体50的开关动作，磁场发生不同的变化，霍尔传感器82可以感应磁场的变化并向主控模块10传输门开关的信号，主控模块10基于门开关感应模块80和微波人感模块20传输的信号来控制照明模块30。
采用这种结构设计，可以兼顾用户对制冷设备内存放物品查看时的照明需求以及对制冷设备使用时如取放物品的照明需求，使箱体内照明模块30的控制更加智能化、合理化，在更好的满足用户的照明需求的同时节约能源。
图11示出了本发明的制冷设备的控制方法，该控制方法的具体步骤如下：
主控模块10控制微波人感模块20持续发射微波信号；
主控模块10控制微波人感模块20持续接收回波信号，根据持续接收到的回波信号判断人的运动状态是否为接近；
若是，主控模块10控制照明模块30在A秒内逐渐变亮，并持续B秒，0≤A≤B，照明模块30位于箱体内部。采用照明模块30逐渐变亮的控制方法，使用户的眼睛不会突然受灯光刺激，有利于提升用户的使用体验。
优选的，A的值可以是1-4之间的任意值。A的值设定在该范围内，可以使照明模块30变亮的时间不会太快，给用户的眼睛适应光亮的时间，又不会太慢，导致无法及时满足用户的照明需求，提升用户的使用体验。
优选的，B的值可以是30-120之间的任意值。B的值设定在该范围内，可以使用户有足够的时间能够看清箱体40内的物品，在满足用户照明需求的同时，又不会亮过长的时间，导致电量的浪费。
采用这种控制方法，可以实现准确检测并判断人的运动状态，其检测精度不受环境温度的影响，从而使人在不开门的情况下能够看清制冷设备内存放的物品的同时节约能源，提升用户的使用体验。
进一步的，为了更加精确地对人进行监测，以保证对制冷设备的精确控制，在本发明较佳实施例中，在前述“根据持续接收到的回波信号判断人的运动状态是否为接近”前还可以增加一个判断前提，如图12所示，具体为：
首先，在主控模块10控制微波人感模块20持续接收回波信号时，根据回波信号计算出人与微波人感模块20之间的距离值S 0以及角度值α 0；
然后，主控模块10判断S 0和α 0是否在设定范围内；
若是,主控模块10根据持续接收到的回波信号判断人的运动状态是否为接近；
若不是，则重复上述步骤。
优选的，距离值S的设定范围可以是：0米-1.5米；角度值α的设定范围可以是：负30度-正30度。采用该设定范围，是大部分用户对制冷设备可能有操作动作或查看需求的范围，可以保证对于有使用意向的用户制冷设备内物品是可视的，同时减少没有使用意向的用户对制冷设备的干扰。
采用这种控制方法，可以将对人运动状态的检测限定于一定的范围内，避免范围过大造成对照明模块30不必要的控制，导致照明模块使用寿命的降低以及电量的浪费，保证在合适距离范围内，对于那些有可能使用该制冷设备的用户是可视的，从而实现对制冷设备更加精确地控制， 在更好的满足用户的需求的同时节约能源。
图13示出了图11所示的本发明的制冷设备的控制方法的进一步优化。该控制方法和图11所示的控制方法的区别在于，该控制方法增加了门开关感应模块，将门开关和微波人感模块结合来控制照明模块。该控制方法的具体步骤如下：
主控模块10获取到开门信号；
主控模块10关闭微波人感模块20；
主控模块10判断箱体40内照明模块30是否处于照明状态；
若是，主控模块10控制照明模块30继续保持照明状态；
若不是，主控模块10控制照明模块30在A秒内逐渐变亮并保持照明状态；
主控模块10获取到关门信号；
主控模块10启动微波人感模块20；
主控模块10判断人的运动状态是否为远离；
若是，主控模块10控制照明模块30在A秒后灭；
若不是，主控模块10控制照明模块30继续亮B秒。
采用这种结构设计，可以兼顾用户对制冷设备内存放物品查看时的照明需求以及对制冷设备使用时如取放物品的照明需求，使箱体内照明模块30的控制更加智能化、合理化，在更好的满足用户的照明需求的同时节约能源。
