本发明实施例的冰箱 100还包括冷冻送风风道 143、第一风道隔板 141、 第二风道隔板 142、 第一支撑块 601、 第二支撑块 602。 第一风道隔板 141 上开设有多个第一冷冻送风口 145。 第二风道隔板 142上开设有多个第二冷 冻送风口 146。 第一风道隔板 141和第二风道隔板 142相对设置， 其间形成 冷冻送风风道 143。 本发明实施例的冰箱 100还包括： 贯流风机 600， 设置 于第一蒸发器部 210和第二蒸发器部 220之间， 贯流风机 600的出风口与冷 冻送风风道 143连通，冷却气流受贯流风机 600带动进入冷冻送风风道 143 , 这样能使回风气流充分利用冷冻蒸发器 200冷却。根据蒸发器长度选用线性 贯流风机 600。 第一支撑块 601设置于箱体 110的后侧壁 111前方。 第二支 撑块 602设置于箱体 110的前部， 与第一支撑块 601相对设置。 第一风道隔 板 141和第二风道隔板 142经第一支撑块 601和第二支撑块 602固定。为了 增加强度， 在第一支撑块 601内部设置有加强柱 610， 在第二支撑块 602内 部设置有加强柱 620。
图 4是根据本发明一个实施例的冰箱 100的示意性仰视图。 图 5是图 4 所示的冰箱 100的压机舱 500的主要部件的立体示意图。 图 6是图 4所示的 冰箱 100的压机舱 500的立体示意图。 本发明实施例的冰箱 100的箱体 110 底部限定有压机舱 500, 且压机舱 500位于冷却室 150的后方， 使得压机舱 500整体处于第一冷冻间室 1401和第二冷冻间室 1402的下方， 如前， 第一 冷冻间室 1401和第二冷冻间室 1402不用再为压机舱 500让位， 保证了第一 冷冻间室 1401和第二冷冻间室 1402的进深，便于放置体积较大不易分割的 物品。 冰箱 100还包括散热风机 502。 散热风机 502可为轴流风机。 压缩机 501、 散热风机 502和冷凝器 503沿横向依次间隔布置在压机舱 500内。
在一些实施例中， 压机舱 500的后壁 （即背板 510） 与压缩机 501对应 的区段 511形成有至少一个后出风孔 512。
在本发明之前， 本领域技术人员通常的设计思路有两种。 一种是在压机 舱 500的后壁分别开设面向冷凝器 503的后进风孔（图中未示出）和开设面 向压缩机 501的后出风孔 512, 在压机舱 500的后壁部分完成散热气流的循 环。 另一种是在压机舱 500的前壁、 后壁分别开设通风孔， 形成沿前后方向 的散热循环风路。 当需要提升压机舱 500散热效果时， 本领域技术人员通常 是通过增加压机舱 500的后壁的后进风孔、后出风孔 512的数量来扩大通风 面积， 或者通过增加冷凝器 503的换热面积来实现， 例如采用换热面积更大 的 U型冷凝器。
发明人创造性地认识到冷凝器 503的换热面积和压机舱 500的通风面积 并不是越大越好：在增加冷凝器 503的换热面积和压机舱 500的通风面积的 常规设计方案中， 会带来冷凝器 503散热不均匀的问题。 对冰箱 100的制冷 系统产生不利的影响。 为此， 本发明提出了在箱体 110的底壁限定横向排布 的临近冷凝器 503的底进风口 505和临近压缩机 501的底出风口 506,这样， 在冰箱 100的底部即完成散热气流的循环， 无需加大箱体 110的后壁与橱柜 的距离。 在减小了冰箱 100所占空间的同时能保证压机舱 500良好的散热， 从根本上解决了嵌入式冰箱 100的压机舱 500散热和空间占用之间无法得到 平衡的痛点， 具有尤其重要的意义。 箱体 110的底壁 504的四角还可设置有 支撑滚轮（图中未示出） ， 箱体 110通过四个支撑滚轮放置于支撑面上， 并 使得箱体 110的底壁 504与支撑面形成一定的空间。
散热风机 502配置为促使底进风口 505周围的环境空气从底进风口 505 进入压机舱 500， 并依次经过冷凝器 503、 压缩机 501， 之后从底出风口 506 流动至外部环境中， 以对压缩机 501和冷凝器 503进行散热。 在蒸气压缩制 冷循环中， 冷凝器 503的表面温度一般低于压缩机 501的表面温度， 故上述 过程中， 使外部空气先冷却冷凝器 503再冷却压缩机 501
在一个优选实施例中， 背板 510面向冷凝器 503的板段 531为连续的板 面， 也即是说板段 531上没有散热孔。 发明人创造性地认识到在不增加冷凝 器 503的换热面积的情况下，减小压机舱 500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。 这是由于板段 531为连 续板面使得进入压机舱 500内的散热气流封闭在冷凝器 503处， 保证了冷凝 器 503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。 同时， 由于板段 531为连续板面， 避免了常规 设计中出风和进风都集中在压机舱 500的后部而导致从压机舱 500吹出的热 风未及时经环境空气冷却而再次进入到压机舱 500中，对冷凝器 503的换热 产生不利影响， 由此保证了冷凝器 503的换热效率。
在一些实施例中， 压机舱 500的两个侧壁上沿横向分别开设有侧通风孔 521 在侧通风孔 521处覆盖有通风盖板 522 通风盖板 522上形成有格栅式 通风小孔。箱体 110的两个侧壁上分别开设有与侧通风孔 521对应的侧开口， 以使得散热气流流动至冰箱 100的外部。 由此进一步增加散热路径， 保证压 机舱 500的散热效果。 可以理解， 也可以是将箱体 110的两个侧壁直接作为 压机舱 500的侧壁， 例如图 6中所示， 侧板 520既构成箱体 110的侧壁又作 为压机舱 500的侧壁。
在一个优选实施例中， 冷凝器 503包括横向延伸的第一直段 532、 前后 延伸的第二直段 533 以及将第一直段 532和第二直段 533连接的过渡曲段 534， 由此形成

503。 前述的背板 510 与冷凝器 503对应的板段 531也即是背板 510面向第一直段 532的板段 531。 由侧通风孔 521进入的环境气流直接与第二直段 533进行换热， 由底进风口 505进入的环境空气直接与第一直段 532进行换热， 由此进一步将进入压机 舱 500内的环境空气更多地集中在冷凝器 503处， 保证冷凝器 503整体散热 的均匀性。
在一个实施例中， 箱体 110的底壁由第一水平板 530、 弯折板 540的一 部分和第二水平板 550共同限定。第一水平板 530位于冰箱 100的底部的前 侦 1|。自第一水平板 530的后端向后上方弯折延伸形成弯折板 540。弯折板 540 延伸至第二水平板 550的上方。 压缩机 501、 散热风机 502及冷凝器 503沿 横向依次间隔布置于第二水平板 550上， 并位于第二水平板 550、 两个侧板 520、背板 510及弯折板 540限定的空间中。弯折板 540包括竖直部 541、倾 斜部 542和水平部 543。 竖直部 541自第一水平板 530的后端向上延伸， 倾 斜部 542由竖直部 541的上端向后上方延伸至第二水平板 550的上方， 水平 部 543由倾斜部 542的后端向后方延伸至背板 510。
第一水平板 530和第二水平板 550间隔设置， 两者之间形成底部开口。 在一个实施例中，冰箱 100还包括分隔件 560。分隔件 560设置于弯折板 540 的后方， 其前部与第一水平板 530的后端连接， 其后部与第二水平板 550的 前端连接， 设置为将底部开口分隔为横向排布的底进风口 505 和底出风口 506 由前述可知， 本发明实施例的底进风口 505和底出风口 506由分隔件 560、 第二水平板 550、 第一水平板 530限定而成， 由此使得底进风口 505 和底出风口 506具有开口尺寸较大的槽形形状， 使得进风面积和出风面积增 大， 进风阻力减小， 气流流通更加顺畅， 而且制造工艺更加简单， 同时压机 舱 500的整体稳定性更强。
倾斜部 542位于第一水平板 530和第二水平板 550的间隙处，位于底进 风口 505和底出风口 506上方。倾斜部 542的斜坡结构还能够对进风气流进 行引导、整流，使得由底进风口 505进入的气流更加集中地流向冷凝器 503 , 避免了气流过于分散而无法更多地通过冷凝器 503， 由此进一步保证了冷凝 器 503的散热效果。 同时， 倾斜部 542的斜坡结构将底出风口 506的出风气 流向底出风口 506 的前侧进行引导， 使得出风气流更加顺畅地流出压机舱 500外部， 由此进一步提升了气流流通的顺畅性。 在一个优选实施例中， 倾 斜部 542与水平面的夹角小于 45°， 此角度时， 倾斜部 542对气流的导向、 整流效果更佳。
此外， 令人意想不到的是， 本申请的发明人创造性地认识到倾斜部 542 的斜坡结构还对气流噪音起到了较好的抑制效果， 在样机试验中， 具有前述 特别设计的倾斜部 542的压机舱 500的噪音可减小 0.65分贝以上。
另外， 传统冰箱中， 箱体 110的底部一般是采用具有大致平板型结构的 承载板， 压缩机 501设置于承载板的内侧， 压缩机 501在运行中产生的振动 对箱体 110底部影响较大。 而本发明实施例中， 如前所述， 箱体 110的底部 构造为一个立体结构， 利用第二水平板 550承载压缩机 501， 减小了压缩机 501振动对箱体 110底部的其他部件的影响。 另外， 通过将箱体 110设计为 如上巧妙的特殊结构， 使得冰箱 100底部的结构紧凑、 布局合理， 减小了冰 箱 100的整体体积，同时充分利用了冰箱 100底部的空间，保证了压缩机 501 和冷凝器 503的散热效率。
在一些实施例中， 冷凝器 503的上端还设置有挡风件 570。 挡风件 570 可为挡风海绵，填充冷凝器 503的上端与弯折板 540之间的空间，也即是说， 挡风件 570覆盖第一直段 532、 第二直段 533及过渡曲段 534的上端， 且挡 风件 570的上端应与弯折板 540抵接， 以密封冷凝器 503的上端， 以免进入 压机舱 500的部分空气从冷凝器 503的上端与弯折板 540之间的空间通过而 不经过冷凝器 503 , 从而使得进入压机舱 500的空气尽可能多的通过冷凝器 503进行换热， 进一步提升冷凝器 503的散热效果。
在一些实施例中， 冰箱 100还包括前后延伸的挡风条 580。 挡风条 580 位于底进风口 505和底出风口 506之间， 由第一水平板 530的下表面延伸至 第二水平板 550的下表面， 并连接分隔件 560的下端， 以利用挡风条 580和 分隔件 560将底进风口 505和底出风口 506完全隔离，从而在冰箱 100置于 一支撑面时， 横向分隔箱体 110的底壁与支撑面之间的空间， 以允许外部空 气在散热风机 502的作用下经位于挡风条 580横向一侧的底进风口 505进入 压机舱 500内， 并依次流经冷凝器 503、压缩机 501， 最后从位于挡风条 580 横向另一侧的底出风口 506流出， 从而将底进风口 505和底出风口 506完全 隔离， 保证进入冷凝器 503处的外部空气与从压缩机 501处排出的散热空气 不会串流， 进一步保证了散热效率。
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。
