如图1-图11所示，本发明提供一种商用风冷冷柜，包括：柜体1、制冷回路、离心风机3和风道盖板4。
其中，柜体1包括外壳11和内胆12，内胆12设置在外壳11中，内胆12和外壳11之间形成保温层。所述制冷回路包括连接在一起的压缩机(未图示)、冷凝器(未图示)、节流装置(未图示)和蒸发器2。离心风机3包括蜗壳31和离心风扇32，蜗壳31的正面形成吸风口301，蜗壳31的下部形成排风口302，离心风扇32位于蜗壳31中；风道盖板4上设置有进风口401和出风口402，进风口401位于出风口402的上方。风道盖板4设置在内胆12中并与内胆12的背部形成风道100，内胆12位于风道盖板4前侧的区域形成储物腔体，离心风机3和蒸发器2位于所述风道中，蜗壳31与风道盖板4之间形成进风区域，进风口401与吸风口301相对布置。
在冷柜实际运行过程中，制冷回路中冷媒在压缩机的作用下循环流动，并通过蒸发器2进行制冷。内胆12中的空气在离心风机3的作用下在风道盖板4的前后侧循环流动，以使得内胆12中的空气经由蒸发器2换热后实现制冷。而针对制冷回路的冷媒循环流动过程以及离心风机3的工作过程，在此不做限制和赘述。
为了有效的增大内胆12中的储物腔体容积，则可以针对内胆12的上部和下部空间进行对应的优化设计，具体结合附图进行说明。
实施例一、针对内胆12的上部空间进行优化设计，则通过减小风道盖板4与蜗壳31之间的距离来实现增大内胆12中储物腔体的容积。具体为，由于离心风机3的吸风口301面对风道盖板4，为了满足离心风机3的进风量要求，则需要在风道盖板4与蜗壳31之间设置足够大的距离，以满足进风量的要求，这样，便会导致内胆12的上部储物空间减小。为此，风道盖板4的顶部与内胆12的顶壁之间形成连通所述风道的辅助风进口403。
在离心风机3运行过程中，内胆12中储物腔体内的空气分别通过进风口401和辅助风进口403进入到进风区域中。进风口401引入的空气直接经由所述吸风孔进入到蜗壳31中，而对于辅助风进口403吸入的空气将从所述吸风孔的周围进入到蜗壳31中。这样，便可以通过辅助风进口403增加进入到进风区域中的空气量，进而便可以在满足进风量的前提下，缩小风道盖板4与蜗壳31之间的距离，进而增大内胆12上部区域的储物空间。
在某些实施例中，为了使得辅助风进口403能够从内胆12的前部区域吸入空气，以加快内胆12内的空气循环流动速度，则风道盖板4的顶部还设置有朝向柜体1前侧方向延伸的顶部盖板43，顶部盖板43与内胆12的顶壁之间形成连通所述风道的回风通道(未标记)。回风通道能在内胆12的顶部延伸到内胆12的前部区域，在离心风机3运行时，内胆 12前部区域的空气便可以被回风通道吸入。这样，便可以使得内胆12中储物腔体中的空气更加均匀的循环流动，使得内胆12中的空气能够更加快速的流动。
进一步的，顶部盖板43上设置有多条纵向布置的导风板44。具体的，导风板44能够对进入到回风通道中的气流进行引导，以使得气流能够均匀的分散至吸风口301的周圈，确保获得更大的吸风量。
优选地，导风板44的后端部向后延伸至风道盖板4外侧，导风板44的后端部还设置有定位板45，定位板45抵靠在蜗壳31上。具体的，在组装时，定位板45能够抵靠在蜗壳31上，以方便将风道盖板4组装到内胆12中并准确的定位固定。而定位板45设置在吸风口301的上方，这样，定位板45与风道盖板4的后背之间形成用于朝向吸风口301方向导风的导风通道(未标记)，从回风通道输出的气流将经由导风通道引导气流流向下方的吸风口301。
在另一些实施例中，风道盖板4包括：上盖板41和下盖板42。其中，上盖板41上形成有进风口401，下盖板42上形成有出风口402；上盖板41位于下盖板42的上方，上盖板41的下边缘与下盖板42的上边缘对接在一起，上盖板41位于蜗壳31的前侧相对布置，下盖板42位于蒸发器2的前侧。具体的，对于风道盖板4采用分体式结构，上盖板41将遮盖住离心风机3，而下盖板42将遮盖住蒸发器2。而上盖板41与下盖板42的连接方式可以采用插接或拼接的方式，在此不做限制和赘述。
在一些实施例中，上盖板41的两侧设置有朝向柜体1后侧方向延伸的翻边结构411，所述翻边结构抵靠在内胆12的背部。具体的，翻边结构411抵靠在内胆12的上并能够将离心风机3的两侧进行遮挡。优选地，所述翻边结构与内胆12的侧壁之间形成间隔，所述翻边结构上还设置有连通所述风道的通风孔412，通风孔412还可以实现内胆12顶部两侧的空气进入到进风区域从而被吸风口301吸入到蜗壳31中。这样，便可以进一步的增大进风量，以满足蜗壳31和风道盖板4之间小距离设置的要求。
优选一实施例中，上盖板41的背面设置有隔条413，隔条413横向布置在进风口401的下方并抵靠在蜗壳31上。具体的，在将离心风机3、蒸发器2和风道盖板4装配到内胆12中后，隔条413抵靠在蜗壳31上，通过隔条413将排风口302和上方的述进风口和吸风口隔离开，以使得从排风口302输出的空气直吹蒸发器2。进而可以避免或减少从排风口302输出的气流受蒸发器2阻挡而反向流到进风区域中，提高了换热效率。
在另一实施例中，为了更大限度的增大内胆12的储物腔体的容积，内胆12的背部还设置有向外突出的外突部121，外突部121在内胆12的内部形成安装凹槽，离心风机3和 蒸发器2设置在所述安装凹槽中。具体的，通过将内胆12的背部形成朝向外壳11方向外突的外突部121，以进一步的增大内胆12内部的容积，并使得离心风机3和蒸发器2安装在外突部121形成的安装凹槽中，以最大限度的增大内胆12中储物腔体的容积。
通过风道盖板与内胆顶部之间形成辅助风进口，辅助风进口能够配合风道盖板上的进风口进风，以满足进风量的要求，这样，便可以使得风道盖板与蜗壳之间的距离进一步的缩小，从而在内胆的顶部预留出更大的空间来存储物品，在整体上增大了内胆的整体储物空间。
实施例二、针对内胆12的下部空间进行优化设计，则通过减小风道盖板4的整体高度尺寸，以使得风道盖板4布置在内胆12的上部区域来实现增大内胆12中储物腔体的容积。具体为，风道盖板4的下部与内胆12的底部之间形成储物间隔。而商用风冷冷柜还包括接水盘5，接水盘5上设置有用于向外排水的排水部50；其中，接水盘5设置在风道盖板4的背面并位于蒸发器2的下方。
在实际使用过程中，通过风道盖板4在内胆12的背部靠上的区域形成风道来安装离心风机3和蒸发器2。这样，便可以在内胆12的下部区域预留出空间来放置物品，以利用风道盖板4下部的区域来增大内胆12中储物腔体的容积。
而由于风道盖板4并没有完全遮盖住内胆12的背部，这样，为了满足蒸发器2的化霜要求，则相对应的，在风道盖板4的背面设置接水盘5，在蒸发器2化霜时，化霜水将滴落到接水盘5中，还有部分化霜水沿着风道盖板4流到接水盘5中，避免出现化霜水在内胆12中随意流淌的现象发生。并且，接水盘5中收集的化霜水最终通过排水部50统一的排出。
在一些实施例中，接水盘5包括：上盘体51、下盘体52和支撑板53。上盘体51上形成有上集水槽511，下盘体52上形成有下集水槽521；上盘体51和下盘体52之间设置有多个支撑板53，相邻两个支撑板53之间形成出风间隔50，上集水槽511与下集水槽521之间还设置有连接流道54，风道盖板4的下部与内胆12的背部之间形成辅助风出口404。
具体的，对于上盘体51而言，上盘体51的边缘将贴靠在风道盖板4的背面，这样，通过上盘体51即可以收集蒸发器2上滴落的化霜水，又可以收集从风道盖板4上流下的化霜水。同时，对于下盘体52而言，下盘体52的边缘则贴靠在内胆12的背部，通过下盘体52即可以收集蒸发器2上滴落的化霜水，又可以收集从内胆12上流下的化霜水。进一步的，上盘体51和下盘体52前后错位布置，上盘体51的垂向投影与下盘体52的垂向投影形成重叠区，这样，便可以避免漏接从蒸发器2上滴落的化霜水。
优选实施例中，下盘体52还设置有朝向内胆12的背部方向延伸的排水流道，所述排水流道与下集水槽521连通，所述排水流道形成排水部50；内胆12的背部还设置有竖向布 置的排水导槽122，所述排水流道插在排水导槽122中。上盘体51和下盘体52收集的化霜水经由排水流道排向排水导槽122中，化霜水将经由排水导槽122的导向流到内胆12的底部，并从内胆12底部的排水口排出至外部。其中，排水导槽122位于内胆12的一侧，接水盘5整体朝向排水导槽122一侧倾斜朝下布置，这样，便可以使得化霜水快速流向接水盘5的一侧，并快速流到排水导槽122中。优选地，上盘体51和下盘体52均倾斜向下并朝向内胆12的背部方向延伸，且下盘体52的边缘贴靠在内胆12的背部。
同样的，也可以采用排水管的方式将接水盘5中的化霜水排出，即排水部50为连通下集水槽521的排水管，所述排水管布置在内胆12的背部。
在一些实施例中，风道盖板4的背面还设置有凸起的挡水筋条421，上盘体51的边缘贴靠在挡水筋条421的下方。具体的，化霜水沿着风道盖板4的背面向下流动，被挡水筋条421阻挡，以使得化霜水越过挡水筋条421再流入到上盘体51中。并配合上盘体51倾斜朝下设置的结构形式，可以减少或避免化霜水沿着风道盖板4的背面流下直接滴落在内胆12中的现象发生，提高了用户体验性。
在另一些实施例中，针对接水盘5的安装方式，则可以采用卡装的方式安装在风道盖板4上，具体的，风道盖板4的背面设置有卡接部422，接水盘5上设置卡接配合部55，接水盘5卡装到风道盖板4上。具体的，卡接部422可以采用卡槽的方式，而卡接配合部55可以采用卡爪的方式，通过卡爪与卡槽配合，使得接水盘5卡装到风道盖板4上，以方便组装。
通过在内胆背部的上部区域布置风道盖板，而风道盖板的下部与内胆的底部之间形成储物间隔，以使得内胆的下部区域获得更大的储物空间，避免风道盖板占据整个内胆背部而造成风道占用了较多内胆内部空间，实现增大了商用风冷冷柜的储物空间。
以上实施例仅用以说明本发明的技术方案，而非对其进行限制；尽管参照前述实施例对本发明进行了详细的说明，对于本领域的普通技术人员来说，依然可以对前述实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或替换，并不使相应技术方案的本质脱离本发明所要求保护的技术方案的精神和范围。
