在一些实施例中， 如图 1所示， 冷却室 133可由冷冻内胆内最下方的空 间进行限定， 也即是说， 冷冻内胆内的下方限定有前述的冷却室 133 , 而冷 冻内胆所限定的冷冻室 131则位于冷却室 133的上方。
送风机 102设置于冷却室 133中， 并位于蒸发器 150的横向第一侧， 配 置为促使至少部分冷却气流经冷冻室送风风道 160向冷冻室 131内流动。
传统冰箱 100中， 冷却室 133—般处于箱体的后部空间中， 冷冻室 131 一般处于箱体的最下方， 压机舱处于冷冻室 131的后下方， 冷冻室 131不可 避免的要做成为压机舱让位的异形空间， 减小了冷冻室 131的存储容积， 并 且还带来了以下多个方面的问题。 一方面， 冷冻室 131所处位置较低， 用户 需要大幅度弯腰或蹲下才能对冷冻室 131进行取放物品的操作， 不便于用户 使用， 尤其不方便老人使用； 另一方面， 由于冷冻室 131进深深度减小， 为 保证冷冻室 131的存储容积， 需要增加冷冻室 131高度方向的空间， 用户在 向冷冻室 131存放物品时需要将物品在高度方向上层叠堆放， 不方便用户查 找物品， 而且位于冷冻室 131底部的物品容易被遮挡， 使得用户不容易发现 而造成遗忘， 导致物品变质、 浪费； 再者， 由于冷冻室 131为异形， 不是一 个矩形空间， 对于一些体积较大且不易分割的物品， 不便放置于冷冻室 131 中。
而本实施例中， 冷冻内胆内的下方空间限定出冷却室 133， 使得冷却室
133占用箱体内的下部空间， 也即是冷却室 133底置， 冷冻室 131位于冷却 室 133的上方， 抬高了冷冻室 131， 降低用户对冷冻室 131进行取放物品操 作时的弯腰程度， 提升用户的使用体验。 同时， 箱体在冷却室 133的后下方 可限定出压机舱， 也即是说， 压机舱位于冷却室 133的后下方， 冷冻室 131 无需再为压机舱让位， 保证冷冻室 131的存储容积， 使得冷冻室 131为一个 矩形空间， 从而可将物品由叠式存放变为平铺展开式存放， 便于用户查找物 品， 节省用户时间和精力； 同时， 也便于放置体积较大不易分割的物品， 解 决无法在冷冻室 131放置较大物品的痛点。
针对冷却室 133位于箱体内的下部空间中，压机舱位于冷却室 133的后 下方的实施例中， 冷却室 133的后下方与压机舱之间发泡料的厚度会直接影 响到冰箱的制冷性能， 申请人在之前申请的专利中， 将送风机 102设置在蒸 发器 150的后方， 该种设计方式增加了冷却室 133前后方向的尺寸， 冷却室 133后方与压机舱之间的间隔空间较小， 降低了冷却室 133与压机舱之间的 发泡料的厚度， 对冰箱 100的制冷性能、 能耗等都产生一定的影响。
送风机 102位于蒸发器 150的横向第一侧，相应地，冷冻室送风风道 160 位于冷冻内胆的横向第一侧壁内侧， 形成有连通冷冻室 131的至少一个第一 送风出口， 送风机 102配置为促使至少部分冷却气流经冷冻室送风风道 160 向冷冻室 131流动。
图 3是根据本发明一个实施例的冰箱 100的第一局部示意图， 图 4是根 据本发明一个实施例的冰箱 100的罩壳 134的示意性结构图。
冰箱 100还包括设置于冷冻内胆 130中的罩壳 134， 罩壳 134罩设在蒸 发器 150上， 罩壳 134的横向第一侧可敞开， 送风机 102位于蒸发器 150的 横向第一侧， 通过罩壳 134横向第一侧的敞开处与冷冻室送风风道 160的连 接， 罩壳 134与冷冻内胆 130的底壁和冷冻内胆 130的横向第一侧壁限定出 前述的冷却室 133。
蒸发器 150整体可呈扁平立方体状横置于冷却室中， 也即蒸发器 150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 150的长度尺寸。 通过将蒸发器 150横置于冷却室 133中， 避免蒸发 器 150占用更多的空间， 保证冷却室 133上部的冷冻室 131的存储容积。
冷却室 133的横向第二侧壁（也即是罩壳 134的横向第二侧壁 1341）形 成有冷冻室回风入口 134a，以在送风机 102的驱动下使冷冻室 131的回风气 流通过冷冻室回风风路 170经冷冻室回风入口 134a进入冷却室 133内由蒸 发器 150进行冷却。冷冻室回风风路 170由冷冻内胆 130的横向第二侧壁与 储物容器 1311之间的间隙限定而成。
申请人之前申请的专利中，冷却室 133的前侧（也即是罩壳 134的前壁） 形成有与冷冻室 131连通的前回风入口， 外部杂物易通过前回风入口进入到 冷却室 133中，而且蒸发器 150化霜过程中，化霜水可能从前回风入口流出， 另外， 冷冻室门体 132打开时， 会有大量温暖湿气从前回风入口进入冷却室 133中， 增大了结霜量。 而本实施例中， 通过在蒸发器 150的横向侧方 （例 如， 横向第一侧） 布置送风机 102， 并在冷却室 133的横向第二侧壁形成与 冷冻室 131连通的冷冻室回风入口 134a， 可有效解决上述问题， 并且使得冷 却室 133前侧的外观更加简洁，用户打开冷冻室门体 132时的视觉感受更好。
冰箱 100的变温内胆位于冷冻内胆 130的上方，变温室送风风道设置于 变温内胆的横向第一侧壁外侧， 位于发泡层中， 具有与变温室 121连通的至 少一个第二送风出口。 冷冻室送风风道 160的顶端设置有变温风门 103， 变 温风门 103可受控打开或关闭， 以将变温室送风风道与冷冻室送风风道 160 连通。
如图 3所示， 冷冻内胆 130的横向第二侧壁 1301与蒸发器 150对应的 区域形成有变温室回风入口 130c，变温室回风风道设置于变温内胆的横向第 二侧壁外侧， 并向下延伸至与变温室回风入口 130c连通。
显然地， 冷却室 133的横向第二侧壁（也即是罩壳 134的横向第二侧壁 1341） 与冷冻内胆 130的横向第二侧壁 1301位于横向同一侧， 相应地， 变 温室回风入口 130c与冷冻室回风入口 134a位于横向同一侧， 通过变温室回 风入口 130c进入的回风气流，再经过冷冻室回风入口 134a进入到冷却室 133 中由蒸发器 150冷却。 具体地， 在送风机 102的驱动下， 变温室 121的回风 气流通过变温室回风风道流动至变温室回风入口 130c,并通过变温室回风入 口 130c和冷冻室回风入口 134a进入冷却室 133内由蒸发器 150进行冷却。
上述冷冻室 131和变温室 121均采用风冷的方式， 而冷藏室 11可采用 直冷方式， 冷藏内胆中配置有冷藏蒸发器（未示出） ， 冷藏蒸发器直接冷却 冷藏室 11。
冷冻内胆 130的底壁位于蒸发器 150正下方的区段记为接水区段，接水 区段大致呈漏斗状， 用于承接蒸发器 150的化霜水， 且接水区段的最低点形 成有前述的排水口 130b， 排水口 130b连接有排水管 140， 化霜水通过排水 管 140被输送到位于压机舱内的蒸发皿（未标号） 中， 一般地， 蒸发皿位于 冷凝器 105的下方， 蒸发皿中的化霜水吸收冷凝器 105的热量蒸发。
图 5是根据本发明一个实施例的冰箱 100的局部分解图， 图 6是根据本 发明一个实施例的冰箱 100的外壳的示意图，图 7是图 6中区域 A的放大图。
一般地， 如图 5所示， 箱体内限定的压机舱中配置有压缩机 104、 冷凝 器 105和散热风机 106， 散热风机 106配置为促使进入压机舱内的气流依次 经过冷凝器 105、 压缩机 104, 之后再流出压机舱。 其中， 散热风机 106可 为轴流风机。 本实施例中， 压缩机 104、 散热风机 106和冷凝器 105沿横向 依次间隔布置于压机舱内。
在一些实施例中， 压机舱的后壁与压缩机 104对应的区段 1162形成有 至少一个后出风孔 1162a。
实际上， 在本发明之前， 本领域技术人员通常的设计思路都是在压机舱 的后壁开设面向冷凝器 105 的后进风孔和开设面向压缩机 104 的后出风孔 1162a, 在压机舱的后部完成散热气流的循环； 或者在压机舱的前壁、 后壁 分别形成通风孔， 形成前后方向的散热循环风路。 在面对提升压机舱散热效 果的问题时， 本领域技术人员通常是增加压机舱后壁的后进风孔、 后出风孔 1162a的数量扩大通风面积， 或者增加冷凝器 105的换热面积， 例如采用换 热面积更大的 U型冷凝器。
而本发明申请人创造性地认识到冷凝器 105的换热面积和压机舱的通风 面积并不是越大越好，在增加冷凝器 105换热面积和压机舱通风面积的常规 设计方案中， 会带来冷凝器 105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， 本发明申请人跳出常规设计思路， 创造性地提出一 种不同于常规设计的新方案， 在箱体的底壁限定有横向排布的临近冷凝器 105的底进风口 110a和临近压缩机 104的底出风口 110b， 在冰箱 100的底 部完成散热气流的循环， 充分利用了冰箱 100与支撑面之间的这一空间， 无 需加大冰箱 100的后壁与橱柜的距离， 减小了冰箱 100所占空间的同时， 保 证压机舱良好的散热， 从根本上解决了嵌入式冰箱 100的压机舱散热和空间 占用之间无法得到平衡的痛点， 具有尤其重要的意义。
散热风机 106 配置为促使底进风口 110a周围的环境空气从底进风口 110a进入压机舱，并依次经过冷凝器 105、压缩机 104,之后从底出风口 110b 流动至外部环境中， 以对压缩机 104和冷凝器 105进行散热。 在蒸气压缩制冷循环中， 冷凝器 105的表面温度一般低于压缩机 104的 表面温度，故上述过程中，使外部空气先冷却冷凝器 105再冷却压缩机 104。
进一步特别地， 在本发明的优选实施例中， （压机舱的后壁） 背板 116 面向冷凝器 105的板段 1161为连续的板面， 也即是说背板 116面向冷凝器 105的板段 1161上没有散热孔。
本发明申请人创造性地认识到即使在不增加冷凝器 105换热面积的前提 下， 反常态的减小压机舱的通风面积， 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。
本发明优选方案中， 申请人突破常规设计思路， 将压机舱的后壁（背板 116）与冷凝器 105对应的板段 1161设计为连续板面， 将进入压机舱内的散 热气流封闭在冷凝器 105处， 使得由底进风口 110a进入的环境空气更多地 集中在冷凝器 105处， 保证了冷凝器 105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 116面向冷凝器 105的板段 1161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的后部而导致从压机 舱吹出的热风未及时经环境空气冷却而再次进入到压机舱中， 对冷凝器 105 的换热产生不利影响， 由此保证了冷凝器 105的换热效率。
在一些实施例中， 压机舱的横向两个侧壁均形成有一个侧通风孔 119a， 侧通风孔 119a可覆盖有通风盖板 108,通风盖板 108形成有格栅式通风小孔; 冰箱 100的外壳包括横向上的两个箱体侧板 111， 两个箱体侧板 111竖向延 伸， 构成冰箱 100的两个侧壁， 两个箱体侧板 111分别形成一个与对应的侧 通风孔 119a连通的侧开口 111a， 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， 保证压机舱的散热效果。
进一步特别地，冷凝器 105包括横向延伸的第一直段 1051、前后延伸的 第二直段 1052以及将第一直段 1051和第二直段 1052连接的过渡曲段 （未 标号） ， 由此形成换热面积适当的 L型冷凝器 105。 前述压机舱的后壁 （背 板 116） 与冷凝器 105对应的板段 1161也即是背板 116面向第一直段 1051 的板段 1161。
由侧通风孔 119a进入的环境气流直接与第二直段 1052进行换热， 由底 进风口 110a进入的环境空气直接与第一直段 1051进行换热， 由此进一步将 进入压机舱内的环境空气更多地集中在冷凝器 105处，保证冷凝器 105整体 散热的均匀性。
进一步特别地， 箱体的外壳还包括底板、 托板 112、 两个侧板 119和一 个竖向延伸的背板 116。 托板 112构成压机舱的底壁， 用于承载压缩机 104、 散热风机 106和冷凝器 105 ,两个侧板 119分别构成压机舱的横向两个侧壁， 竖向延伸的背板 116构成压机舱的后壁。
进一步特别地，底板包括位于底部前侧的底部水平区段 113及从底部水 平区段 113的后端向后上方弯折延伸的弯折区段， 弯折区段延伸至托板 112 的上方， 压缩机 104、 散热风机 106及冷凝器 105沿横向依次间隔布置于托 板 112上， 并位于托板 112、 两个侧板 119、 背板及弯折区段限定的空间中。
托板 112与底部水平区段 113共同构成箱体的底壁， 托板 112与底部水 平区段 113间隔设置， 以利用托板 112的前端和底部水平区段 113的后端的 间隔空间形成与外部空间连通的底开口。 其中， 弯折区段具有位于底进风口 110a和底出风口 110b上方的倾斜区段 114。
具体地，弯折区段可包括竖直区段 1131、倾斜区段 114和顶部水平区段 115 , 竖直区段 1131由底部水平区段 113的后端向上延伸， 倾斜区段 114由 竖直区段 1131 的上端向后上方延伸至托板 112的上方， 顶部水平区段 115 由倾斜区段 114的后端向后方延伸至背板，以遮蔽压缩机 104、散热风机 106 及冷凝器 105的上方。
进一步特别地， 冰箱 100还包括分隔件 117, 分隔件 117设置于弯折区 段的后方， 其前部与底部水平区段 113的后端连接， 其后部与托板 112的前 端连接，设置为将底开口分隔为横向排布的底进风口 110a和底出风口 110b。
由前述可知，本实施例的底进风口 110a和底出风口 110b由分隔件 117、 托板 112、 底部水平区段 113限定而成， 由此形成了开口尺寸较大的槽形的 底进风口 110a和底出风口 110b， 增大了进风、 出风面积， 减小了进风阻力， 使得气流流通更加顺畅， 而且制造工艺更加简单， 使得压机舱的整体稳定性 更强。
特别地， 本发明申请人创造性认识到， 倾斜区段 114的斜坡结构能够对 进风气流进行引导、 整流， 使得由底进风口 110a进入的气流更加集中地流 向冷凝器 105 , 避免了气流过于分散而无法更多地通过冷凝器 105， 由此进 一步保证了冷凝器 105的散热效果； 同时， 倾斜区段 114的斜坡将底出风口 110b的出风气流向地出风口的前侧进行引导，使得出风气流更加顺畅地流出 压机舱外部， 由此进一步提升了气流流通的顺畅性。
进一步特别地， 在优选的实施例中， 倾斜区段 114与水平面的夹角小于 45 ° ， 在该实施例中， 倾斜区段 114对气流的导向、 整流效果更好。
并且， 令人意想不到的是， 本申请发明人创造性地认识到倾斜区段 114 的斜坡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 计的倾斜区段 114的压机舱的噪音可减小 0.65分贝以上。
另外，传统冰箱 100中，箱体的底部一般具有大致平板型结构的承载板， 压缩机 104设置于承载板内侧，压缩机 104运行中产生的振动对箱体底部影 响较大。而本实施例中，如前所述，箱体的底部由特殊结构的底板和托板 112 构造为一个立体结构，为压缩机 104布置提供独立的立体空间，利用托板 112 承载压缩机 104,减小压缩机 104振动对箱体底部的其他部件的影响。另外， 通过将箱体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 104和冷凝器 105的散热效率。
进一步特别地， 冷凝器 105的上端设置有挡风件 1056, 挡风件 1056可 为挡风海绵， 填充冷凝器 105的上端与弯折区段之间的空间， 也即是说， 挡 风件 1056覆盖第一直段 1051、第二直段 1052及过渡曲段的上端，且挡风件 1056的上端应与弯折区段抵接， 以密封冷凝器 105的上端， 以免进入压机舱 的部分空气从冷凝器 105的上端与弯折区段之间的空间通过而不经过冷凝器 105 , 从而使得进入压机舱的空气尽可能多的通过冷凝器 105进行换热， 进 一步提升冷凝器 105的散热效果。
进一步特别地， 冰箱 100还包括前后延伸的挡风条 107， 挡风条 107位 于底进风口 110a和底出风口 110b之间， 由底部水平区段 113下表面延伸至 托板 112下表面，并连接分隔件 117的下端，以利用挡风条 107和分隔件 117 将底进风口 110a和底出风口 110b完全隔离， 从而在冰箱 100置于一支撑面 时， 横向分隔箱体的底壁与支撑面之间的空间， 以允许外部空气在散热风机 的作用下经位于挡风条 107横向一侧的底进风口 110a进入压机舱， 并依次 流经冷凝器 105 , 压缩机 104, 最后从位于挡风条 107横向另一侧的底出风 口 110b流出， 从而将底进风口 110a和底出风口 110b完全隔离， 保证进入 冷凝器 105处的外部空气与从压缩机 104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。
