本实施例提供了一种冰箱 10,下面参照图 1至图 12来描述本发明实施例的冰箱 10。 在下文描述中， “前” 、 “后” 、 “上” 、 “下” 、 “左” 、 “右” 、 等指示的方位或 位置关系为基于冰箱 10本身为参考的方位， “前” 、 “后”为如图 5、 图 6、 图 11和图 12所指示的方向， 如图 1和图 4所示， “横向”是指与冰箱 10宽度方向平行的方向。
如图 1和图 2所示， 冰箱 10—般性地可包括箱体 100， 箱体 100包括外壳 110和设 置在外壳 110内侧的储物内胆， 外壳 110与储物内胆之间的空间中填充有保温材料 （形 成发泡层）， 储物内胆中限定有储物间室， 储物内胆一般可包括冷冻内胆 130、冷藏内胆 120等，储物间室包括由冷冻内胆 130内限定的冷冻室 132和由冷藏内胆 120内限定的冷 藏室 121。 储物内胆的前侧还设置有门体， 以打开或关闭储物间室， 图 1、 图 2均隐去了 门体。
如本领域技术人员可意识到的， 本实施例的冰箱 10还可包括蒸发器 101、 送风风机
（本实施例中， 送风风机为离心风机 103） 、 压缩机 104、 冷凝器 105以及节流元件 （未 示出）等。 蒸发器 101经由制冷剂管路与压缩机 104、 冷凝器 105、 节流元件连接， 构成 制冷循环回路， 在压缩机 104启动时降温， 以对流经其的空气进行冷却。
特别地， 本实施例中， 箱体 100内限定有位于下方的冷却室， 而冷却室的上方为储 物间室， 蒸发器 101设置于冷却室中， 以冷却进入冷却室中的气流， 形成冷却气流。
传统冰箱 10中， 冷却室一般处于箱体 100的后部空间中， 冷冻室 132—般处于箱体 的最下方， 压机舱处于冷冻室 132的后方， 冷冻室 132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 132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 132所处位置较低， 用户需要大幅度弯腰或蹲下才能对冷冻室 132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 132进深 深度减小， 为保证冷冻室 132的存储容积， 需要增加冷冻室 132高度方向的空间， 用户 在向冷冻室 132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 132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 132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 132中。
而本实施例中， 冷却室处于箱体 100的下方， 使得冷却室占用箱体 100内的下部空 间， 而储物间室处于冷却室的上方， 冷却室的后下方可限定出压机舱， 储物间室无需再 为压机舱让位， 保证储物间室的存储容积。
具体地， 冷却室可由冷冻内胆 130进行限定， 冷冻内胆 130—般位于箱体 100的下 部， 冷冻内胆 130 内限定出冷却室和位于冷却室上方的冷冻室 132。 由此抬高了冷冻室 132, 降低用户对冷冻室 132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， 冷冻室 132无需再为压机舱让位， 使得冷冻室 132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， 节省用户的时间和精力； 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 132放置较大物品的痛点。
一般地， 冰箱 10还包括位于冷冻内胆 130上方的其他储物内胆， 该储物内胆可为变 温内胆 131或冷藏内胆 120。本实施例中， 变温内胆 131位于冷冻内胆 130的上方， 冷藏 内胆 120位于变温内胆 131的上方。 变温内胆 131 内限定有变温室 1311， 如图 1、 图 2 所示， 变温内胆 131为两个， 两个变温内胆 131横向分布， 每个变温内胆 131限定有一 个变温室 1311。
如本领域技术人员所熟知的， 冷藏室 121 内的温度一般处于 2°C至 10°C之间， 优先 为 4°C至 7°C。冷冻室 132内的温度范围一般处于 -22°C至 -14°C。变温室 1311可随意调到 -18°C至 8°C。 不同种类的物品的最佳存储温度并不相同， 适宜存放的位置也并不相同， 例如果蔬类食物适宜存放于冷藏室 121， 而肉类食物适宜存放于冷冻室 132。
冷藏内胆 120内可限定有冷藏风道 （未示出） ， 冷藏风道中设置有冷藏蒸发器 （未 示出） 和冷藏风机 （未示出） ， 以对冷藏室 121进行独立送风。
在离心风机 103的驱动下， 冷却气流经送风风道 141输送至冷却室上方的至少一个 储物间室内。本实施例中， 冷却气流经送风风道 141输送至冷冻室 132。 如图 1所示， 送 风风道 141位于冷冻内胆 130的后壁内侧， 送风风道 141形成有与冷冻室 132连通的冷 冻室进风口 141a， 以将至少部分冷却气流输送至冷冻室 132内。 一般地， 冷冻内胆 130 的后壁形成有向后凹陷与送风风道 141匹配的凹部， 送风风道 141嵌入该凹部内。
每个变温内胆 131的后壁后侧可设置有变温室风道 （未示出） ， 变温内胆 131的后 壁形成有与变温室风道的出风口连通的变温室进风口 131a， 变温室风道配置为可受控地 连通送风风道 141， 以将送风风道 141的部分冷却气流输送至变温室 1311中。
如图 7所示， 送风风道 141顶端形成有至少一个第一顶开口 141g， 第一顶开口 141g 与变温室风道的进风口一一对应， 冷冻内胆 130 的顶壁形成有与至少一个第一顶开口 141g—对应的至少一个第二顶开口 130d， 以通过第二顶开口 130d将第一顶开口 141g 与变温室风道的进风口连通。送风风道 141的第一顶开口 141g处可设置有风门， 以受控 打开或关闭第一顶开口 141g。 如图 1所示， 变温内胆 131为两个， 相应地， 变温室风道 为两个， 第一顶开口 141g、 第二顶开口 130d均为两个。
以下对冷冻内胆 130和冷却室进行具体说明：
如图 3和图 4所示， 在一些实施例中， 冷冻内胆 130的横向两个侧壁与冷却室对应 的区域分别向冷却室方向凸出， 以分别形成一个第二限位凸台 130b。
冰箱 10还包括罩板， 罩板构成冷却室的顶壁和前壁， 并与两个第二限位凸台 130b、 两个冷冻内胆 130的侧壁位于对应的第二限位凸台 130b前方的区段、冷冻内胆 130的底 壁及冷冻内胆 130的后壁共同限定出冷却室。
蒸发器 101整体可呈扁平立方体状横置于冷却室中， 也即蒸发器 101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 101的长度尺寸。 通过将蒸发器 101横置于冷却室中， 避免蒸发器 101 占用更多的空间， 保证冷却室上部 的冷冻室 132的存储容积。
如图 2所示， 罩板包括顶盖 1021和至少一个前盖组 102, 顶盖 1021位于蒸发器 101 的上方， 每个前盖组 102的前侧形成有至少一个前回风入口， 以使得冷冻室 132的回风 气流通过该至少一个前回风入口进入冷却室中由蒸发器 101进行冷却， 从而在冷却室和 冷冻室 132之间形成气流循环。
在一些实施例中， 如图 1所示， 前盖组 102为两个， 两个前盖组 102沿横向分布， 每个前盖组 102的前侧形成有两个前回风入口， 分别为为第一前回风入口 102a和第二前 回风入口 102b。
冷冻内胆 130的侧壁形成有侧回风入口（未示出）， 侧回风入口通过侧回风通道（未 示出）与变温内胆 131连通， 以利用侧回风通道将变温室 1311的回风气流输送至冷却室 中进行冷却， 从而在变温室 1311与冷却室之间形成气流循环。
优选地，侧回风入口形成于冷冻内胆 130的侧壁位于对应的第二限位凸台 130b前方 的区段，使得侧回风入口更加靠前， 以使得变温室 1311的回风气流从蒸发器 101 的前方 向后流动， 延长变温室 1311的回风气流与蒸发器 101的换热路径， 提升换热效率。
冷冻内胆 130的底壁的后部区段形成有向上凸出的至少一个第一限位凸台 130a， 每 个第一限位凸台 130a形成有限位槽 130al ; 送风风道 141 的下部区段形成有与限位槽 130al配合的配合部 141f， 配合部 141f与限位槽 130al配合， 可防止送风风道 141下移。
如图 3所示， 第一限位凸台 130a为两个， 两个第一限位凸台 130a在横向上间隔分 布， 相应地， 配合部 141f为两个， 两个配合部 141f在横向上间隔分布。
一般地， 位于冷冻内胆 130中的送风风道 141的下部区段不可避免地要与冷冻内胆
130的底壁之间形成间隔空隙， 冰箱 10装配完成后， 正常情况下， 送风风道 141的顶端 的第一顶开口 141g应与冷冻内胆 130的顶壁对应的第二顶开口 130d密封配合。
而冰箱 10在运输过程中，当受到碰撞时易导致送风风道 141下坠，使得送风风道 141 的顶端的第一顶开口 141g与冷冻内胆 130的顶壁对应的第二顶开口 130d之间出现缝隙。 冰箱 10运行过程中， 变温室 1311中的气流会通过缝隙进入到冷冻室 132中， 而由于变 温室 1311的气流温度一般高于冷冻室 132的气流温度， 导致送风风道 141的顶端附近结 霜， 对冷冻室 132的温度和冷却气流的输送产生影响。本实施例中， 通过对冷冻内胆 130 的底壁和送风风道 141的下部区段进行如上特别的设计，可避免冰箱 10运输过程中受到 碰撞而导致送风风道 141下坠， 保证冰箱 10运行过程中的制冷效果。
冷冻内胆 130的底壁的横向两侧临近后端的位置分别形成有向上凸出的一个第三限 位凸台 130c，两个第三限位凸台 130c与冷冻内胆 130的底壁位于蒸发器 101后方的区段 限定出布置离心风机 103的空间。
每个第三限位凸台 130c可形成有第一安装孔（未标号） 。 离心风机 103的蜗壳形成 有与两个第一安装孔一一对应的第二安装孔 103cl ,以通过依次穿过第二安装孔 103cl和 第一安装孔的安装件 （例如， 螺钉） 将离心风机 103的蜗壳安装于冷冻内胆 130的底壁 上。 例如， 如图 8、 图 10所示， 下盒体 1032的侧壁的横向两侧分别形成有一个安装板 103c， 安装板 103c形成有与对应的第一安装孔对应的第二安装孔 103cl o
以下对离心风机 103和送风风道 141进行具体说明：
离心风机 103位于蒸发器 101的后方， 包括蜗壳和设置于蜗壳内的叶轮 1031， 送风 风道 141与蜗壳可拆卸连接， 并使得送风风道的风道进风口与蜗壳的蜗壳出风口连通， 以使得蜗壳内的气流进入送风风道 141中。
现有冰箱 10中，风道与风机的蜗壳多是一体式结构，不方便运输，无法进行模块化， 而本实施例中， 送风风道 141与离心风机 103的蜗壳采用分体式设计， 实现模块化， 方 便拆装和运输， 提 良品率。
蜗壳包括下盒体 1032和设置在下盒体 1032上的上盖体 1033 ,下盒体 1032与上盖体 1033可扣合连接，方便蜗壳的拆卸和装配。上盖体 1033的后端和下部均敞开，也即是说， 上盖体 1033包括顶壁 103a和由顶壁 103a向下延伸的第一侧壁 103d； 相应地， 下盒体 1032的后端和上部均敞开，下盒体 1032包括底壁 103b和由底壁 103b向上延伸的第二侧 壁。上盖体 1033的顶壁 103a形成有蜗壳进风口 1033a，上盖体 1033的后端与下盒体 1032 的后端限定出蜗壳出风口。
上盖体 1033与下盒体 1032扣合后， 上盖体 1033的第一侧壁 103d位于下盒体 1032 的第二侧壁的内侧，也即是说，上盖体 1033的第一侧壁 103d与上盖体 1033的顶壁 103a 以及下盒体 1032的底壁 103b限定出蜗壳内的送风风道。
参见图 9, 上盖体 1033的第一侧壁 103d具有蜗型线， 构造成蜗壳风道， 更好地引导 气流向蜗壳出风口流动，降低噪音。上盖体 1033的顶壁 103a的内面形成有蜗型槽 103a3 , 蜗型槽 103a3与上盖体 1033的第一侧壁 103d进行配合， 更好地引导气流流动。 例如， 上盖体 1033的顶壁 103a的第七倾斜直段的内面形成有蜗型槽 103a3 o蜗型槽 103a3形成 有前述的蜗壳进风口 1033a，叶轮 1031设置于蜗型槽 103a3与下盒体 1032限定的区域内。
叶轮 1031的转轴轴线与竖直线的夹角 0可为 20° 至 35 ° ， 例如， 0为 20° 、 25 ° 、 33。 、 35。 等。
离心风机 103的蜗壳的前端面与蒸发器 101的后端面之间的水平距离 a可为 15mm 至 35mm， 例如， a为 15 mm、 20 mm、 25 mm、 30 mm、 35 mm, 避免因离心风机 103 与蒸发器 101距离过小而造成离心风机 103结霜。
下盒体 1032的底壁 103b可形成有至少一个排水孔 103b3 ,如图 10所示，排水孔 103b3 为两个， 以便于排出可能形成的冷凝水。
送风风道 141位于离心风机 103的后方，包括位于前侧的风道前盖板 1411和位于后 侧的风道后盖板 1412,风道前盖板 1411和风道后盖板 1412可扣合装配。风道前盖板 1411 与上盖体 1033可拆卸连接， 风道后盖板 1412与下盒体 1032可拆卸连接， 使得蜗壳出风 口与送风风道 141的风道进风口连通。
如图 6所示， 风道后盖板 1412可包括位于下部的竖向延伸的后竖板段 1412e和由后 竖板段 1412e的下端向前下方弯折延伸的接合段， 接合段位于风道前盖板 1411的下方， 接合段的前端与风道前盖板 1411的下端限定出风道进风口。 风道后盖板 1412通过接合 段与下盒体 1032可拆卸连接， 前述的配合部 141f则形成于该接合段上。
本实施例中， 风道后盖板 1412被设计为具有由后竖板段 1412e下端向前下方弯折延 伸的接合段， 便于与前方的离心风机 103 的蜗壳连接， 促使蜗壳内的气流平缓地进入送 风风道 141内， 降低噪音。 同时， 接合段形成与冷冻内胆 130底壁的限位槽 130al相配 合的配合部 141f，使得风道后盖板 1412与冷冻内胆 130和离心风机 103的蜗壳均能积极 配合， 整体布局更加紧凑、 合理。 如图 6所示， 风道后盖板 1412的接合段包括由后竖板段 1412e向前下方弯曲延伸的 过渡曲段 1412a、由过渡曲段 1412a向前下方倾斜延伸的第一倾斜直段 1412b和由第一倾 斜直段 1412b向前前后延伸的水平直段 1412c。
水平直段 1412c的前端形成有向下竖向延伸的第一立板 1412d，第一立板 1412d由水 平直段 1412c的横向一侧延伸至另一侧， 第一立板 1412d的前立面形成有向前凸出的至 少一个第一卡扣 141c，第一立板 1412d的后立面可形成有向后凸出的前述的配合部 141fo 下盒体 1032的底壁 103b的后端形成有向下竖向延伸的第二立板 103bl， 第二立板 103bl由下盒体 1032的底壁 103b的横向一侧延伸至另一侧，第二立板 103bl的下端形成 有与至少一个第一卡扣 141c—对应并适配的第一缺口 103bl l , 第一卡扣 141c卡入对 应的第一缺口 103bl l并与第二立板 103bl的前立面勾持， 以将下盒体 1032扣合在风道 后盖板 1412上。
第一卡扣 141c为两个，三个第一卡扣 141c横向间隔分布，相应地，第一缺口 103bl l 为三个， 三个第一缺口 103bl l横向间隔分布。
下盒体 1032与风道后盖板 1412扣合时，第一立板 1412d的前立面与第二立板 103bl 的后立面接近贴合， 两者之间存在较小的间隔缝隙， 该间隔缝隙中可塞入海绵条， 避免 漏风。
如图 6所示， 风道前盖板 1411包括位于下部的竖向延伸的前竖板段 1411a， 前竖板 段 1411a的前壁面形成有向前凸出的至少一个第二卡扣 141b。

第二卡扣 141b为两个，两个第二卡扣 141b横向间隔分布，相应地，第二缺口 103al l 为两个， 两个第二缺口 103al l横向间隔分布。
前竖板段 1411a的横向尺寸应等于或大于第三立板 103al的横向尺寸， 如图 8所示， 前竖板段 1411a的横向尺寸与第三立板的 103al横向尺寸大致相同， 以使得上盖体 1033 与风道前盖板 1411扣合时， 前竖板段 1411a能够完全遮挡第三立板 103al o 上盖体 1033 与风道前盖板 1411扣合时， 前竖板段 1411a的后立面与第三立板 103al的前立面接近贴 合， 两者之间存在较小的间隔缝隙， 该间隔缝隙中可塞入海绵条， 避免漏风。
前竖板段 1411a的后壁可形成有向后凸出的多个加强筋 141e, 增强前竖板段 1411a 的强度。
第三立板 103al 的前立面形成有沿横向间隔分布的多个加强筋 103a2， 第三立板 103al还形成有凸出于第三立板 103al上方的安装部 141h， 例如， 安装部 141h形成于第 三立板 103al的横向中部位置， 安装部 141h形成有第一螺钉孔， 前竖板段 1411a与安装 部 141h对应的区域形成有与第一螺钉孔对应的第二螺钉孔， 以利用穿过第一螺钉孔和第 二螺钉孔的螺钉将上盖体 1033与风道前盖板 1411装配。

本实施例的冰箱 10中，箱体 100底部限定有压机舱，且压机舱位于冷却室的后下方， 如前， 冷冻室 132不用再为压机舱让位， 保证了冷冻室 132的进深， 便于放置体积较大 不易分割的物品。
如图 11所示， 冰箱 10还包括散热风机 106, 散热风机 106可为轴流风机， 压缩机 104、 散热风机 106和冷凝器 105沿横向依次间隔布置在压机舱内。
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 10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， 如图 11和图 12所 示， 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 10的底部完成散热气流的循环， 充分利用了冰箱 10与支撑面 之间的这一空间， 无需加大冰箱 10的后壁与橱柜的距离， 减小了冰箱 10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 10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 10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 10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 10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 100的壳体包括底板、托板 112、两个侧板 119和竖向延伸的背 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和从底部水平区段 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、 背板 116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 100的底壁， 且托板 112与底部水平区 段 113间隔分布， 以利用底部水平区段 113的后端与托板 112的前端限定出底开口， 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。两个侧板由 托板 112的横向上的两侧分别向上延伸至弯折区段的横向上的两侧， 以封闭压机舱的横 向两侧； 背板 116由托板 112的后端向上延伸至弯折区段的后端。
具体地， 弯折区段可包括竖直区段 1131、 前述的倾斜区段 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。
箱体 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 10中， 箱体 100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 100底部影响较大。而本实 施例中， 如前所述， 箱体 100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 100底部的其他部件的影响。 另外， 通过将箱体 100设计为如上巧妙的特殊 结构， 使得冰箱 10底部的结构紧凑、 布局合理， 减小了冰箱 10的整体体积， 同时充分 利用了冰箱 10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。
冰箱 10还包括前后延伸的挡风条 107, 挡风条 107位于底进风口和底出风口之间， 由底部水平区段 113下表面延伸至托板 112下表面， 并连接分隔件的下端， 以利用挡风 条 107和分隔件将底进风口和底出风口完全隔离， 从而在冰箱 10置于一支撑面时， 横向 分隔箱体 100的底壁与支撑面之间的空间， 以允许外部空气在散热风机 106的作用下经 位于挡风条 107横向一侧的底进风口进入压机舱内，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流出， 从而将底进风口和底出风口完全隔 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。
