具体的，如图1和图2所示，所述制冷机组100，包括机座10、设置于机座10内并通过管路连接的压缩机20、冷凝器30、蒸发器40，所述机座10包括安装蒸发器40的保温部件11。本实施例中，机座10还包括覆盖于保温部件11外部的罩壳(图中未示出)，以提高整个制冷组件100的密封性能，并在罩壳上开设出风口102和回风口101，以连通制冷设备200内的储物间室。
进一步的，配合参照图3所示，所述保温部件11具有容置蒸发器40的第一腔室11a、连通第一腔室11a且竖直深度大于第一腔室11a的第二腔室11b。本实施例中，保温部件11内部的储物空间横截面形状呈倒置“L”的型，由于保温部件11采 用该特殊形状，压缩机20及给冷凝器30散热的风扇等高度相对较大的元件，可以设置于竖直深度较小的第一空间11a的正下方，从而充分利用机座10内部空间，节约制冷机组100的占用空间。
进一步的，所述制冷机组100还包括沿竖向设置于第二腔室11b内的离心风机50，所述离心风机50具有朝向第一腔室11a开放设置的吸风口51，所述蒸发器40沿横向设置于第一腔室11a内并正对于所述吸风口51。
本实施例中，通过在保温部件11内形成第一腔室11a以及竖直深度大于第一腔室11a的第二腔室11b，将蒸发器40沿横向设置于第一腔室11a内、将离心风机50沿竖向设置于第二腔室11b，合理利用保温部件11的内部空间，以降低整个制冷机组100的体积，从而提升制冷设备内储物空间的利用率。
而且，由于蒸发器40正对于离心风机50的吸风口51，使得经蒸发器40降温后的气流直接被离心风机50抽入制冷设备200的储物间室内，避免冷量在保温部件11滞留而造成冷量的损耗，提升制冷设备的制冷效率。
具体的，所述保温部件11具有位于第一腔室11a底部的第一底壁11c、位于第二腔室11b底部的第二底壁11d、连接第一底壁11c与第二底壁11d的第三底壁11e、合围于第一底壁11c、第二底壁11d和第三底壁11e周围的保温外壁11f，所述蒸发器40设置于第一底壁11c上，所述离心风机50匹配设置于保温外壁11f内并与第三底壁11e相对设置。
本实施例中，蒸发器40贴合于第一底壁11c上，离心风机50除了吸风口51以外的外壁均贴合于保温外壁11f上，从而最大限度地降低保温部件11的占用空间。由于离心风机50的外侧除了吸风口51以外均匹配抵接于保温外壁11f内，从而避免离心风机50因工作时产生的振动而在保温部件11内发生水平方向的偏移，也利于离心风机50定位安装于保温部件11内。而且，第三底壁11e沿竖向设置，与离心风机50相对设置，从而提供给离心风机50吸风口51一侧作用力，进一步抵消离心风机50工作时产生的振动。
进一步的，所述第一底壁11c自连接第三底壁11e的一端朝向远离第三底壁11e的一端竖直高度逐渐增加，所述蒸发器40沿第一底壁11c平行设置。
本实施例中，如图3，蒸发器40沿第一底壁11c倾斜设置，使得同等前后距离下蒸发器40的散热体积更大，气流与蒸发器40换热时间较长，换热效果好，一定程度上节约了保温部件11的前后空间。而且，回风口101与第一腔室11a相连通，出风口102与离心风机50的排风口相对接，储物间室内的回风从第一腔室11a水平高度较高处进入，经过蒸发器40充分换热后，从第一腔室11a水平高度较低处进入吸风口，这样一来，确保下沉的冷空气能够被离心风机50充分地送入储物间室内。
另外，由于第一底壁11c的倾斜设置，还能够利于蒸发器40上的化霜水流动，不会积聚于第一底壁11c上。
进一步的，配合参照图4所示，所述保温外壁11f具有连接第二底壁11d并与第三底壁11e相对设置的第一侧壁11f1、连接于第一侧壁11f1两端的第二侧壁11f2和第三侧壁11f3。本实施例中，第三底壁11e与第一侧壁11f1相互平行设置，第二侧壁11f2与第三侧壁11f3相互平行设置。
进一步的，配合参照图5所示，所述离心风机50还具有风机叶片53、安装风机叶片53的安装座55。本实施例中，整个离心风机50具有三组风机叶片53，并安装于同一个安装座55，提升离心风机50的功率的同时，节约整个离心风机50的占用空间。
进一步的，所述安装座55固定于第二侧壁11f2和第三侧壁11f3上并沿第一侧壁11f1平行设置。本实施例中，安装座55同时抵接于第二侧壁11f2和第三侧壁11f3，并且通过紧固件固定于第二侧壁11f2和第三侧壁11f3的顶部，便于操作人员的安装。第一侧壁11f1平行于竖直方向设置，安装座55与第一侧壁11f1平行设置，能 够节约离心风机50占用的前后空间，从而降低整个保温部件11的前后空间。
进一步的，所述保温外壁11f还具有设于第二侧壁11f2和第三侧壁11f3上并朝向第一腔室11a内凸起的抵接凸台11f4，所述抵接凸台11f4位于第一底壁11c靠近第三底壁11e的一侧，以抵接于蒸发器40相邻离心风机50的一侧。
本实施例中，蒸发器40的左右两侧抵接于第二侧壁11f2和第三侧壁11f3上，限制蒸发器40沿左右方向的偏移。蒸发器40放置于倾斜设置的第一底壁11c上，利用抵接凸台11f4抵接于蒸发器40，从而抵消蒸发器40受重力沿平行于第一底壁11c的分力，使得蒸发器40稳定地设置于第一底壁11c上。
进一步的，所述保温外壁11f还具有连接第二侧壁11f2与第三侧壁11f3的第四侧壁11f5。本实施例中，如图3所示，第四侧壁11f5的外壁与第一侧壁11f1相互平行设置，第四侧壁11f5的内壁则沿前后方向倾斜设置，有利于回风气流平顺地进入第一腔室11a内。
进一步的，所述第一底壁11c上设有自上端面向下凹陷的导流槽11c1，所述导流槽11c1沿第四侧壁11f5朝向第三底壁11e方向延伸设置，并沿第二侧壁11f2朝向第三侧壁11f3方向间隔设置。
本实施例中，导流槽11c1的设置，有利于蒸发器40形成的化霜水往第二腔室11b流动，避免蒸发器40底部与第一底壁11c相互冻结在一起。而且，由于导流槽11c1位于蒸发器40底部的第一底壁11c上，有利于气流从蒸发器40底部进行换热，提高换热效率。
具体的，所述导流槽11c1自第四侧壁11f5朝向第三底壁11e凹陷深度逐渐增大。本实施例中，回风气流从第四侧壁11f5处进入导流槽11c1，由于第四侧壁11f5处的导流槽11c1深度较浅，刚进入的回风气流只能少量地通过导流槽11c1，这样可以避免回风气流未经蒸发器40换热，直接从导流槽11c1流向吸风口51。而随着气流流向吸风口51的过程中，导流槽11c1的深度逐渐增大，能够加快气流被吸风口51吸入，从而提高保温部件11内气流的流动速度。
进一步的，所述离心风机50还具有连接安装座55并形成吸风口51的风机罩57，所述第三底壁11e上设置朝向第一底壁11c方向凹陷并与风机罩57相匹配的汇流槽11e1，所述汇流槽11e1与导流槽11c1的一端相连通。
本实施例中，由于第三底壁11e上设置有与汇流槽11e1相匹配的风机罩57，一方面便于离心风机50定位安装于保温部件11内，另一方面使得保温部件11内部空间更加紧凑。另外，汇流槽11e1能够将多个导流槽11c1内的气流进行汇聚，从而便于吸风口51吸入，进一步加速保温部件11内气流的流动。
进一步的，配合参照图6所示，所述第二底壁11d上设有与安装座55相匹配的定位凸台11d1。本实施例中，定位凸台11d1抵接于安装座55的底部，从而避免离心风机50因工作时产生的振动而在保温部件11内发生竖直方向的偏移。而且，还方便离心风机50与保温部件11定位安装，在离心风机50安装后，保温部件11的内部更加紧凑，进一步降低保温部件11的体积。
进一步的，在第二底壁11d上于相邻定位凸台11d1之间设有引流槽11d2，所述引流槽11d2内设有贯穿第二底壁11d的排水孔11d3。本实施例中，如图6，引流槽11d2的截面呈“V”型结构，便于第二底壁11d上液体的集聚，最终通过排水孔11d3排出保温部件11。第一腔室11a和第二腔室11b内产生的液体受重力后，均通过排水孔11d3排出保温部件11，并流向机座10内的接水盒，在接水盒内受热蒸发排出机座10。
