本发明的冰箱，由于出风管的进风端连接于压机舱，出风端处于箱体的顶部前侧，压机舱内经过换热之后的散热气流能够进入出风管，并从箱体的顶部向前排出，因此，无论该冰箱是单独使用，还是被嵌装于橱柜使用，向前排出散热气流不会受到橱柜的干扰，通风性好，并且从顶部排出的热空气无法直接地吹向用户，不会引用用户的不适感。
进一步地，本发明的冰箱，散热气流进口设置于底钢，也即向下敞开，这样箱体与地面之间底部空间的空气可以由散热气流进口进入压机舱内。当冰箱被嵌装于橱柜时，由于冰箱的底部空间在底脚的支撑下向前敞开，因此冰箱前方空间的空气可以经底部空间和散热气流进口进入压机舱内，使得压机舱的进风侧保持良好的通风性。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明

具体实施方式
在本实施例的描述中，需要理解的是，术语“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“进深”等指示的方位或置关系为基于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”指的是朝向用户的一侧。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。
参见图1，图1是根据本发明一个实施例的冰箱1的示意性局部透视图。本发明提供一种冰箱1，该冰箱1既适合单独使用，又适合嵌装于橱柜中使用。一般性地，该冰箱1可包括箱体10和门体(图中未示出)。
箱体10可包括外壳12和多个内胆，外壳12位于整体冰箱1的最外侧，以保护整个冰箱1。多个内胆被外壳12包裹，并且多个内胆与外壳12之间的空间中填充有保温材料 (形成保温层14)，以降低内胆向外散热。每个内胆可以限定出向前敞开的储物空间，并且储物空间可以被配置成冷藏室、冷冻室、变温室等等，具体的储物空间的数量和功能可以根据预先的需求进行配置。
门体的数量还可与内胆的数量一致，即每个内胆向前敞开的储物间室均可由其对应的门体进行开闭。门体可动地设置于箱体10的前方，例如门体可以通过铰接的方式设置箱体10前部的一侧，通过枢转的方式开闭储物空间。
参见图2，图2是根据本发明一个实施例的冰箱1中制冷循环系统20的示意图。在一些实施例中，该冰箱1还可包括用于为这些储物间室提供冷量的循环制冷系统30。该循环制冷系统30还可包括冷媒流路中的压缩机21、冷凝器22、除露管23、节流装置24和蒸发器26等。
压缩机21作为制冷系统的动力，其通过压缩作用提高制冷剂蒸气的压力和温度，创造将制冷剂蒸气的热量向外界环境介质转移的条件，即将低温低压制冷剂蒸气压缩至高温高压状态，以便能用常温的空气或水作冷却介质来冷凝制冷剂蒸气。
冷凝器22是一个热交换设备，利用环境将来自压缩机21的高温高压制冷蒸气的热量带走，使高温高压制冷剂蒸气冷却、冷凝成高压常温的制冷剂液体。
除露管23连接在冷凝器22的出口，由于冷凝器22的出口的制冷剂处于常温状态，相对于储物间室，此处制冷剂处于高温，因此，当制冷剂通过除露管23时可对周围的部件进行加热，避免结霜。具体地，除露管23可设置在箱体10需要加热除露的位置，例如冰箱1的中梁内等。
节流装置24(其可为毛细管)可串接在冷凝器22的出口，降低制冷剂液体的压力，而且降低制冷剂液体的温度，以将冷凝器22排出高压常温的制冷剂液体变成低温低压制冷剂，从而排入蒸发器26进行相变吸热。
蒸发器26可设置在箱体10内，以直接或间接地向冰箱1的储物间室提供冷量。例如压缩式直冷冰箱1中，蒸发器26可设置于内胆的后壁面外侧或内侧。压缩式风冷冰箱1中，箱体10内还具有蒸发器室，蒸发器室通过风路系统与储物间室连通，且蒸发器室内设置蒸发器26，出口处设置有风机，以向储物间室进行循环制冷。
该冰箱1的箱体10后侧底部设置有压机舱30，压缩机21和冷凝器22设置于压机舱30内。由于压缩机21在工作时产生热量，冷凝器22需要及时冷却压缩机21排出的高温冷媒，因此需要对压机舱30进行散热。压机舱30可通入冰箱1外部的空气，形成散热气流，并与压机舱30内的蒸发器和冷凝器22进行换热，换热之后的散热气流排出压机舱30，将热量带出压机舱30。
参见图1至图7，图3是根据本发明一个实施例的冰箱1的示意性前视透视图，图4是根据本发明一个实施例的冰箱1的截面图，图5是根据本发明另一个实施例的冰箱1的截面图，图6是根据本发明一个实施例的冰箱1的部分部件的分解图，图7是根据本发明一个实施例的冰箱1的示意性俯视透视图。
在一些实施例中，该冰箱1还可包括出风管40，出风管40的进风端连接于压机舱30，出风管40的出风端处于箱体10的顶部前侧，且向前敞开，以将压机舱30内的散热气流导引至箱体10的顶部，并向前排出。
在本实施例中，由于出风管40的进风端连接于压机舱30，出风端处于箱体10的顶部前侧，压机舱30内经过换热之后的散热气流能够进入出风管40，并从箱体10的顶部向前排出，因此无论该冰箱1是单独使用，还是被嵌装于橱柜使用，向前排出散热气流不会受到橱柜的干扰，通风性好。而且从顶部排出的热空气无法直接地吹向用户，不会引用用户的不适感。
参见图1和图3，在一些实施例中，冰箱1还包括压机舱壳300，压机舱壳300设置于箱体10的后侧下方，以限定出压机舱30。压机舱壳300具有散热气流进口301和散热气流出口302，散热气流出口302与散热气流进口301分布于压机舱30的横向两侧，压缩机21和冷凝器22二者均位于散热气流进口301和散热气流出口302之间。
散热气流进口301和散热气流出口302分别处于压机舱壳300的横向两侧，压缩机21和冷凝器22二者均位于散热气流进口301和散热气流出口302之间，这样由散热气流进口301进入压机舱30的散热气流能够流经压缩机21和冷凝器22后，从散热气流出口302排出，实现对压缩机21和冷凝器22散热。
需要说明的是，本实施例仅限定了压缩机21和冷凝器22二者的整体相对于散热气流进口301、散热气流出口302之间的位置关系，而并未限定压缩机21和冷凝器22之间位置关系。也即是，在本实施例中，压缩机21可比冷凝器22更加靠近散热气流进口301，或者，冷凝器22还可比压缩机21更加靠近散热气流进口301。
参见4至图6，进一步地，压机舱壳300还包括底钢320、位于底钢320两侧的两个侧板340、位于底钢320后侧的背板330、以及位于底钢320上方的盖板310，盖板310、底钢320、背板330和两个侧板340共同限定出压机舱30，并且散热气流进口301设置于底钢320。
散热气流进口301设置于底钢320，也即向下敞开，这样箱体10与地面之间底部空间的空气可以由散热气流进口301进入压机舱30内。当冰箱1被嵌装于橱柜时，由于冰箱1的底部空间在底脚的支撑下向前敞开，因此冰箱1前方空间的空气可以经底部空间和散热气流进口301进入压机舱30内，使得压机舱30的进风侧保持良好的通风性。
参见图1、图3至图5，在一些实施例中，出风管40还可包括第一管段42和第二管段44。第一管段42的第一端作为出风管40的进风端，并连接于散热气流出口302，并且第一管段42自其第一端沿箱体10向上延伸，使其第二端处于箱体10的顶部。第二管段44的第一端连接于第一管段42的第二端，并沿箱体10向前延伸，第二管段44的第二端作为出风管40的出风端，并处于箱体10的顶部前侧。
第一管段42的设计方案可以为多种，其可根据散热气流出口302的位置、橱柜的内部环境等因素具体设计。
参见图4，例如，由于压机舱30整体处于箱体10的后侧，因此第一管段42可直接设置在箱体10的后侧，并沿箱体10的后侧自下而上地延伸至箱体10的顶部。又例如，第一管段42还可设置在箱体10的侧部，并沿箱体10的侧部自下而上地延伸至箱体10的顶部。再例如，第一管段42还可自其箱体10的侧壁弯折至箱体10的后壁并延伸至顶部。
第二管段44的第一端连接在第一管段42的第二端，并沿着箱体10的顶部自前向后地延伸至箱体10的前侧。但是，需要注意的是，第二管段44的第二端(出风管40的出风端)不宜超出于箱体10的前侧，这样不会对箱体10前方的门体造成干涉，也不会影响冰箱1的美观性。
参见图3，此外，第二管段44的还可设置成扁平状，以使其在高度方向上不超出于位于箱体10顶部的电控盖13、铰链盖14等部件，不会增加箱体10的整体高度，也可起到隐藏第二管段44的作用。
此外，出风管40可直接设置在箱体10的外壳12外部(图4)，也可以设置在箱体10内的保温层14中(图5)。如图4所示，当设置在外壳12外部时，还可考虑在外壳12上形成凹槽，以容纳出风管40，以使其不会凸出箱体10的外表面，实现隐藏出风管40的作用。
参见图4，在一些具体的实施例中，散热气流出口302可设置于压机舱壳300的背板330上。第一管段42和第二管段44均处于箱体10的外部。
结合图6，通常，箱体10的外壳12一般可包括U壳12a和后背板12b，U壳12a用于构成箱体10的顶壁和两个侧壁。后背板12b设置在U壳12a的后方，用于构成箱体10的后壁。压机舱壳300的背板330的上端与外壳12的后背板12b下端相对接，以共同构成整个冰箱1的后壁。
当散热气流出口302设置在压机舱壳300的背板330上时，也即处于外壳12的后侧，这样第一管段42的第一端可以设置在背板330的后侧，与散热气流出口302相连接，并向上延伸至箱体10的顶部。此时，后背板12b以及U壳12A的顶板(箱体10的顶壁)上对应地为第一管段42和第二管段44分别形成凹槽，以容纳第一管段42和第二管段44。
参见图5，在另外一些具体的实施例中，散热气流出口302设置于压机舱壳300的盖板310。第一管段42和第二管段44均处于箱体10的保温层14内。
盖板310可作为压机舱壳300的顶壁，这样当压机舱壳300设置在箱体10的后侧下方时，盖板310的部分处于外壳12的内部，也即盖板310具有与保温层14相对的部分。当散热气流出口302设置在盖板310与保温层14相对的部分时，第一管段42可沿着保温层14向上延伸，第二管段44也可设置在箱体10顶部的保温层14内，并向前延伸，最终延伸至箱体10的前表面。
在该实施例中，由于第一管段42和第二管段44设置在箱体10的保温层14内，因此，在安装时，第一管段42和第二管段44可预先安装在外壳12内，然后通过发泡工艺形成保温层14时固定第一管段42和第二管段44。
参见图7，在一些实施例中，在前后方向上，散热气流进口301设置成比散热气流出口302更加靠前，这样进入压机舱30的气流的流动路径可以向后倾斜，这样延长压机舱30内散热气流的路径，更加充分地利用压机舱30的宽度，提高换热效率。
此外，在上述实施例中，为了便于连接出风管40，散热气流出口302本身就可压机舱壳300的背板330或者与保温层14相对的盖板310。在前后方向上，这些位置本身就比较靠后，只需要将设置在底钢320上的散热气流进口301位置向前移动即可实现散热气流进口301比散热气流出口302更加靠前。
参见图7，在一些实施例中，冷凝器22可设计成扁平状，并且冷凝器22较宽的一面设置成自后向前且向靠近散热气流进口301倾斜。这样在设计冷凝器22时可以酌情减小厚度，而增大较宽一面的面积，使其更加扁平，这样能够使冷凝器22充分利用压机舱30的前后距离，增大冷凝器22的迎风面积(较宽一面更宽)，降低冷凝器22的透风阻力(厚度更薄)，提高散热气流与冷凝器22之间的换热效率。
参见图7，在一些实施例中，该冰箱1还可包括进风风道50，进风风道50设置于箱体10的底部空间，其前端向箱体10的前方敞开，其后端与散热气流进口301连通，以将箱体10前方的空气导引至压机舱30。
也即，散热气流的流动路径：箱体10前方的空气向后进入箱体10底部的进风风道50，然后由设置在底钢320上的散热气流进口301进入压机舱30内，在压机舱30内散热气流横向流经冷凝器22和压缩机21，然后由散热气流出口302进入出风管40的第一管段42、第二管段44，最终从箱体10的顶部向前排出，形成循环。
在一些具体的实施例中，进风风道50可以由独立的风道管限定而成。风道管直接安装在箱体10的底部，并与散热气流进口301相连，以便将箱体10前方的空气导引至压机舱30内。
在另外一些具体的实施例中，进风风道50还可由箱体10的底面以及多个导风条共同限定而成。多个导风条设置在箱体10的底部，以与箱体10的底部共同限定出向前敞开的进风风道50。
参见图1和图3，在一些实施例中，该冰箱1还可包括扇热风扇60，扇热风扇60设置于出风管40的进风端，以促使压机舱30内的散热气流进入其内，并从出风端排出。
由于出风管40的进风端与散热气流出口302相连，因此，扇热风扇60既可设置在压机舱30内，也可设置在出风管40内。
扇热风扇60的具体形式可也灵活选择。例如，当散热气流出口302设置在背板330上上时，也即散热气流出口302向后敞开，而第一管段42向上送风，因此扇热风扇60可选用离心风扇，以改变散热气流的出风方向，提高送风效率。又例如，当散热气流出口302设置于盖板310时，散热气流出口302与第一管段42均向上，因此扇热风扇60可选用小型贯流风扇，以提高风量和送风距离，保证良好的通风性。
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。
