具体实施方式
在本实施例的描述中，需要理解的是，术语“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“竖直”、“水平”、“顶”、“底”、“进深”等指示的方位或位置关系为基于冰箱正常使用状态下的方位作为参考，并参考附图所示的方位或位置关系可以确定，例如指示方位的“前”指的是冰箱朝向用户的一侧、“横向”是指与冰箱宽度方向平行的方向。这仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制
图1是根据本发明一个实施例的冰箱的示意性前视图。图2是图1所示的冰箱的示意性侧剖图。冰箱一般性地可包括箱体10，箱体10包括外壳、内胆以及其他附件构成。外壳是冰箱的外层结构，保护着整个冰箱。为了隔绝与外界的热传导，在箱体10的外壳和内胆之间加有隔热层，隔热层一般通过发泡工艺构成。内胆可以分为一个或多个，内胆根据功能可以被划分为冷藏内胆、变温内胆、冷冻内胆等，具体的内胆个数以及功能可以根据冰箱的使用需求进行配置。本实施例中内胆至少包括底部内胆110，底部内胆110 一般可为冷冻内胆。
底部内胆110设置于压机舱400的上方，其限定有储物空间。底部内胆110一般可为冷冻内胆，底部内胆110限定出储物空间以及位于储物空间下方的冷却室100。蒸发器60可以布置于冷却室100的中前部。箱体10底部限定有压机舱400，且压机舱400位于冷却室100的后方，也就是说压机舱400位于底部内胆110的下部后方。压机舱400在水平面上的投影位于蒸发器60在水平面上投影的后方，即压机舱400与蒸发器60在水平方向上交错放置，降低蒸发器60的设置高度，增大储物空间的容积。底部内胆110的底壁在冷却室100的后部具有从前到后向上倾斜设置的内胆倾斜部111，该倾斜角度范围设置为30°至40°，例如可以设置为33°、35°、38°，优选为36.7°。压机舱400的顶板230包括与内胆倾斜部111平行间隔设置的顶板倾斜部231，冷凝器40的倾斜角度与顶板倾斜部231的倾斜角度一致，该倾斜角度范围设置为30°至40°，例如可以设置为33°、35°、38°，优选为36.7°，从而用于为压机舱400提供足够的空间。
如本领域技术人员可意识到的，本实施例的冰箱还包括制冷系统。制冷系统包括节流元件(图中未示出)、蒸发器60、制冷风机30、压缩机20以及与压缩机20连接的冷凝器40。蒸发器60配置成直接或间接地向储物空间内提供冷量。冰箱通过风路系统实现制冷气流在蒸发器60与储物空间内的循环。由于制冷系统本身的循环构造以及工作原理，为本领域技术人员习知且易于实现的，为了不掩盖和模糊本申请的发明点，后文对制冷系统本身不做赘述。
蒸发器60由制冷剂管路与压缩机20、冷凝器40、节流元件连接，共同构成制冷循环回路。在压缩机20启动时，蒸发器60流经的空气进行冷却。本实施例中，冷冻内胆位于箱体10的下部，其内限定有位于底部的冷却室100。蒸发器60设置于冷却室100中。具体地，蒸发器60整体呈扁平长方体状，横置于冷却室100中，也即蒸发器60的长、宽面平行于水平面，厚度面垂直于水平面放置，而且厚度尺寸明显小于蒸发器60的长度尺寸。通过将蒸发器60横置于冷却室100中，避免蒸发器60占用更多的空间，保证冷却室100上部的储物空间的存储容积。在一些实施例中，蒸发器60也可倾斜地设置于冷却室100内，提高风循环效率与排水效率。
在一些实施例中，冰箱中的制冷风机30设置于冷却室100中的内胆倾 斜部111上，配置为将回风气流吸入冷却室100中，由蒸发器60进行冷却，并促使冷却后的气流向储物空间流动。本实施例的冰箱还包括向储物空间提供制冷气流的送风风道与制冷风机30的出风端连通，配置为将经蒸发器60冷却后的部分气流输送至储物空间中。送风风道设置于冷冻内胆的后壁内侧，具有连通储物空间的多个送风出口。冷却室100的前侧形成有与储物空间连通的至少一个前回风入口，以使得储物空间的回风气流通过至少一个前回风入口进入冷却室100中由蒸发器60进行冷却，从而在冷却室100和储物空间之间形成气流循环。
制冷风机30可以为离心风机。制冷风机30整体位于蒸发器60的后方制冷风机30的排风口位于后侧，并配置成向斜后方送风。送风风道与离心风机的排风口连通，并向上延伸，配置成将制冷气流输送至储物空间。在储物空间的后壁开有与送风风道连通的送风口，将制冷气流排入储物空间。
结合图3-图9所示。压机舱400内部设置有压缩机20、散热风机50、冷凝器40以及用于安装冷凝器40的挡风板220。压机舱400还包括顶板230、底板210、背板240以及两侧的侧板250。压缩机20以及冷凝器40沿箱体10横向方向间隔布置于压机舱400内，压机舱400在冷凝器40的前方开设有与箱体10外部连通的气流吸入口2121。当散热风机50启动时，环境气流从气流吸入口2121进入压机舱400，经过冷凝器40，使冷凝器40散热。
冷凝器40沿箱体10的进深方向有前到后向上倾斜设置，充分利用了压机舱400有限的空间，符合压机舱400的空间特点，可有效地利用气流吸入口2121中吸入的空气，使得空气充分与冷凝器40接触，增强散热效果。
挡风板220设置于压机舱400开设气流吸入口2121一侧，并且沿箱体10的进深方向从前到后向上倾斜设置，冷凝器40固定于挡风板220上，使得从气流吸入口2121进入的空气沿挡风板220流经冷凝器40，以对冷凝器40进行散热。蒸发皿214设置于挡风板220下方，用于承接蒸发器60产生的冷凝水。挡风板220相对于蒸发皿214倾斜设置，使得固定于挡风板220上的冷凝器40与蒸发皿214中的冷凝水保证一定距离，避免长期接触冷凝水而导致冷凝器40被腐蚀，缩短使用寿命。蒸发皿214设置于冷凝器40下，可利用冷凝器40产生的热量将蒸发皿214中冷凝水蒸发，同时也可为冷凝器40降温散热。
箱体10具有底板210，底板210包括第一板部211及第二板部212。第 一板部211作为压机舱400的底壁，第二板部212从第一板部211的前端向前延伸。第一板部211上设置有用于承接来自于冷却室100化霜水的蒸发皿214以及压机支撑座(图中未示出)。冷凝器40设置于蒸发皿214的上方，压缩机20安装于压机支撑座上。第二板部212在蒸发皿214的前部开设有气流吸入口2121，第二板部212在压缩机20的前部开设有气流排出口2122。进一步地，本实施例的冰箱的气流吸入口2121以及气流排出口2122可以均设置为格栅状，也即通过格栅之间的通风孔与箱体10外部连通，避免异物(例如小动物等)通过气流吸入口2121或气流排出口2122进入箱体10内部。在一些实施例中，冰箱的蒸发皿214是顶部具有开口的大致为长方体的结构，具有底壁和自底壁向上延伸的四个侧壁。
压机舱400内的气流流动方向为：箱体10底部的空气从气流吸入口2121进入压机舱400，经由冷凝器40后，进入冷凝器40后部与背板240之间的间隔，流向压缩机20，最终从压缩机20前部的气流排出口2122排出箱体10。上述散热气流可以带走冷凝器40以及压缩机20的热量，保证冰箱制冷系统正常运行。
冷凝器40沿箱体10的进深方向从前到后向上倾斜设置，可有效地利用气流吸入口2121中吸入的空气，使得空气充分与冷凝器40接触面积增大，增强散热效果。具体地，冷凝器40整体呈扁平长方体状，其垂直于挡风板220方向的厚度小于其从前到后的长度以及其沿箱体10横向方向的宽度，即冷凝器40相对于挡风板220沿厚度方向较薄，沿长度方向扩大，充分利用挡风板220的板面空间，可使得冷凝器40大面积地与空气接触，增强散热效果。冷凝器40前端低点可以设置为与气流吸入口2121在竖直方向上平齐，从气流吸入口2121进入的空气可直接接触冷凝器40，使得换热更加充分。
冷凝器40可以为翅片冷凝器，其翅片沿箱体10进深方向平行排列，并且翅片冷凝器40的冷凝管包括贯穿翅片的直管段以及设置于翅片两侧用于连接直管段的连接管段。翅片设置为沿进深方向平行排列且冷凝器40整体沿箱体10进深方向倾斜，当空气从气流吸入口2121进入后，可流畅地通过翅片间缝隙与每片翅片充分接触并换热，大大增强了散热效果。在一些实施例中，冷凝器40还可以使用微通道式换热器。
挡风板220迎风侧的板面设置有多个固定柱221，固定柱221的顶端形成卡槽2211，连接管段卡接于卡槽2211内，以将翅片冷凝器40固定于挡风 板220上。通过卡槽2211将冷凝器40稳固的安装在挡风板220上，结构简单，且由于卡槽2211的特殊设计，安装过程简洁方便。
挡风板220在冷凝器40两侧还设置有密封条，避免从气流吸入口2121进入的空气从冷凝器40的两侧散出。密封条可设置在冷凝器40两侧和上部，目的是使进入的空气需完全通过冷凝器40才可进入冷凝器40后部空间，使得冷凝器40散热充分。
冰箱还包括散热风机50。散热风机50设置于冷凝器40与压缩机20之间，并配置成促使形成从气流吸入口2121依次流经冷凝器40以及压缩机20后向气流排出口2122排出的散热气流。在一些实施例中，冰箱还包括风机固定架(图中未示出)。风机固定架沿前后方向固定在压机舱400内，位于压缩机20与冷凝器40之间，用于固定散热风机50。
当散热风机50启动时，外部空气从气流吸入口2121进入压机舱400内，经挡风板220导流与冷凝器40均匀接触对冷凝器40进行散热，而后经散热风机50吹过压缩机20，带走压缩机20运行时所产生的部分热量，增加压缩机20的使用寿命，而后从压缩机20前方的气流排出口2122吹出。
在底板210的底面上设置有分隔件213，并配置成隔离气流吸入口2121以气流排出口2122。以允许外部空气在散热风机50的作用下经位于分隔件213一侧的气流吸入口2121进入压机舱400内，并一侧流经冷凝器40、压缩机20，最后从位于分隔件213另一侧的气流排出口2122流出，以防止排出后的气体直接进入气流吸入口2121，导致气体在箱体10附近小范围内循环，降低散热效率。具体地，分隔件213可以为长条状，宽度可以为底板210的底面与地面的距离。冷凝器40的后端与压机舱400的后壁之间、冷凝器40靠近压缩机20的一侧与散热风机50之间分别具有间隔，该间隔可以减小散热气流的风阻。
在一个优选实施例中，背板240面向冷凝器40的区段为连续的板面，也即是说背板240面向冷凝器40的板段上没有散热孔。申请人创造性地认识到即使在不增加冷凝器40换热面积的前提下，反常态的减小压机舱400的通风面积，能够形成更加良好的散热气流路径，而且仍然可达到较好的散热效果。在本发明的优选方案中，申请人突破常规设计思路，将背板240与冷凝器40对应的板段设计为连续板面，将进入压机舱400内的散热气流封闭在冷凝器40处，使得由气流吸入口2121进入的环境空气更多地集中在冷 凝器40处，保证了冷凝器40各个冷凝段的换热均匀性，并且有利于形成更加良好的散热气流路径，同样可达到较好的散热效果。并且，由于背板240面向冷凝器40的板段为连续板面，不具有进风孔，避免了常规设计中出风和进风都集中在压机舱400的后部而导致从压机舱400吹出的热风未及时经环境空气冷却而再次进入到压机舱400中，对冷凝器40的换热产生不利影响，由此保证了冷凝器40的换热效率。
本实施例中的冰箱的压机舱400设置于箱体10的底部后方。压机舱400中设置有压缩机20，散热风机50，挡风板220以及冷凝器40。挡风板220沿箱体10的进深方向倾斜设置，冷凝器40固定于挡风板220上。挡风板220的前方开设有气流吸入口2121。当散热风机50启动时，空气从气流吸入口2121进入压机舱400内，与冷凝器40充分接触后进入冷凝器40后部空间，再通过散热风机50导入压缩机20出，从而带走压缩机20运行产生的热量，在经由气流排出口2122排出压机舱400。通过挡风板220与冷凝器40的倾斜设置，增大了气流与冷凝器40的接触面积，使冷凝器40充分散热，从而优化了冰箱的散热性能，改善了散热结构。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
