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
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具 体实施例。 附图中相同的附图标记标示了相同或类似的部件或部分。 本领域 技术人员应该理解， 这些附图未必是按比例绘制的。 附图中： 图 1是根据本发明一个实施例的冰箱的示意图；
图 2是根据本发明一个实施例的冰箱的过滤板的示意图；
图 3是根据本发明一个实施例的冰箱的局部示意图； 以及
图 4是根据本发明一个实施例的冰箱的局部分解示意图。 具体实施方式
本实施例提供了一种冰箱 100, 下面参照图 1至图 4来描述本发明实施 例的冰箱 100。 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 100本身为参考的方位，“前”、 “后”为如图 1、 图 3、 图 4所指示的方向， “横向”也即是指左右方向， 是指与冰箱 100宽度方向平行的方向。
如图 1、 图 2所示， 冰箱 100包括箱体， 箱体一般性地包括外壳 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。
如本领域技术人员可意识到的， 箱体还限定有冷却室 135和压机舱， 冰 箱 100还可包括蒸发器 101、送风机 103、压缩机 104、冷凝器 105以及节流 元件（未示出）等。 蒸发器 101设置于冷却室 135中， 压缩机 104和冷凝器 105设置于压机舱中，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。
为排出蒸发器 101的化霜水， 一般地， 冷却室 135的底壁形成有排水口 130a。特别地， 本实施例中， 冰箱 100还包括过滤板 136, 其位于蒸发器 101 的下表面与排水口 130a之间， 并与蒸发器 101的下表面和排水口 130a均间 隔， 且过滤板 136形成有贯穿其上表面和下表面的多个通孔 136a。
若蒸发器 101化霜不完全，凝结在蒸发器 101上的冰块掉落在过滤板 136 上， 过滤板 136具有通孔 136a， 只允许非常小尺寸的冰块通过， 减小了排水 口 130a附近的冰块体积， 降低了冰堵概率。 另外， 蒸发器 101化霜过程中， 加热蒸发器 101的加热丝的热量会传递至过滤板 136上， 掉落在过滤板 136 上的冰块经过二次融化， 可减小冰块体积， 极大的降低了融化排水口 130a 处冰块的加热丝工作负荷。
其中， 过滤板可为铝板， 其热传导性能良好， 更加有利于冰块的融化。 临近排水口 130a的通孔 136a的尺寸小于远离排水口 130a的通孔 136a 的尺寸， 由此可尽量减小排水口 130a附近的冰块体积， 进一步降低排水口 130a冰堵概率。
冷却室 135的底壁上表面包括位于蒸发器 101正下方的接水区段，接水 区段在平行于冷却室 135横向侧壁的竖直面的投影包括由后向前呈向下倾斜 延伸的后倾斜直段 1302和由后倾斜直段 1302的前端向前上方倾斜延伸前倾 斜直段 1301，后倾斜直段 1302与前倾斜直段 1301的交接处形成有前述的排 水口 130a。 由此使得排水口 130a处于蒸发器 101的下方。
现有冰箱 100中，蒸发器 101的下方的接水区段一般只具有一个倾斜斜 面， 该倾斜斜面的最低点 （排水口的位置） 一般位于蒸发器 101的下游， 通 过排水口 130a进入冷却室 135的热空气未经过蒸发器 101，易在位于蒸发器 101下游的送风机 103上结霜或结冰， 或者直接进入到冷冻室 131中， 影响 冷冻室 131的温度。
本实施例中， 通过设计具有前述特别构造的接水区段，使得排水口 130a 处于蒸发器 101的下方， 通过排水口 130a进入冷却室 135的热空气会先经 过蒸发器 101， 由蒸发器 101冷却后再进入到冷冻室 131中， 或者， 在蒸发 器 101上结霜 （在后续的化霜阶段， 蒸发器 101上的霜层再被融化） ， 从而 避免对送风机 103和冷冻室 131的影响。
如图 1和图 2所示， 过滤板 136则与蒸发器 101的下表面与接水区段之 间限定的空间内， 过滤板 136可包括位于后倾斜直段 1302的上方并由后向 前呈向下倾斜延伸的后倾斜板段 1362和由后倾斜板段 1362的前端向前上方 倾斜延伸的前倾斜板段 1361， 由此在后倾斜板段 1362与前倾斜板段 1361 的交接处构成过滤板 136的最低处。
如图 2所示， 后倾斜板段 1362和前倾斜板段 1361均应形成有多个通孔 136a， 且后倾斜板段 1362与前倾斜板段 1361的交接处的通孔 136a相连通， 也即是说， 后倾斜板段 1362在交接处的一排通孔 136a与前倾斜板段 1361 在交接处的一排通孔 136a连通， 防止化霜水聚集在后倾斜板段 1362和前倾 斜板段 1361直接的交接处。
过滤板 136在平行于冷却室 135横向侧壁的竖直面的投影的最低点位于 接水区段在平行于冷却室 135横向侧壁的竖直面的投影的最低点的正上方。
过滤板 136在平行于冷却室 135横向侧壁的竖直面的投影的最低点与蒸 发器 101在该竖直面投影的最低点之间的距离和与接水区段在平行于冷却室 135横向侧壁的竖直面的投影的最低点的距离相同，也可理解为，过滤板 136 位于蒸发器 101与接水区段之间的 1/2处。
进一步特别地，储物内胆包括位于最下方的冷冻内胆 130,冷冻内胆 130 内限定有冷冻室 131和位于冷冻室 131正下方的前述的冷却室 135， 冷冻内 胆 130的底壁则构成冷却室 135的底壁。
相对于冷却室 135位于冷冻室 131后方的传统冰箱 100， 本实施例的冰 箱 100， 冷却室 135不再占用冷冻室 131后方的空间， 加大了冷冻室 131的 进深尺寸， 增加了冷冻室 131的存储容积。 再者， 冷却室 135的存在抬高了 其上方的冷冻室 131的高度， 降低用户对该冷冻室 131进行取放物品操作时 的弯腰程度， 提升用户的使用体验， 尤其方便老人使用。
冷却室 135可由罩扣在冷冻内胆 130的底壁上的罩壳（未标号）与冷冻 内胆 130的底壁限定而成。
蒸发器 101整体可呈扁平立方体状横置于冷却室 135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 135中， 避免蒸 发器 101占用更多的空间， 保证冷却室 135上部的冷冻室 131的存储容积。
箱体还包括冷冻室送风风道 134和送风机 103， 冷冻室送风风道 134位 于冷冻内胆 130的后壁内侧， 具有与冷冻室 131连通的至少一个冷冻室送风 口， 送风机 103设置于蒸发器 101的后方， 配置为促使由蒸发器 101冷却后 的至少部分气流经冷冻室送风风道 134流动至冷冻室 131中。
罩壳的后端形成有与冷冻室送风风道 134的进风口连通的出风口， 以便 于冷却室中经蒸发器 101冷却的气流进入冷冻室送风风道 134中， 罩壳的前 壁形成有前回风入口 135a， 冷冻室 131的回风气流通过前回风入口 135a进 入冷却室中由蒸发器 101进行冷却。
如图 1所示， 箱体包括冷藏内胆 120和变温内胆， 变温内胆位于冷冻内 胆 130的正上方， 其内限定有变温室 141， 而冷藏内胆 120位于变温内胆的 正上方，其内限定有冷藏室 121。冷冻内胆 130的前侧设置有冷冻室门体 132, 冷藏内胆 120的前侧设置有冷藏室门体 122, 变温内胆的前侧设置有变温室 门体 142。
冷藏室 121 可由竖向上间隔分布的多个横隔板 123 分隔为多个储物空 间， 以便于物品的分类存放，变温室 141中配置有储物容器 143 ,冷冻室 131 中配置有储物抽屉 133。
箱体还包括变温室送风风道 144和变温室回风风道 （未示出） ， 如图 1 所示，变温室送风风道 144可通过变温室风门 145与冷冻室送风风道 134可 受控地连通，变温室回风风道具有与变温内胆连通的进口和与冷却室 135连 通的出口， 以将变温室 141的回风气流输送至冷却室 135中。
如图 1所示， 冷藏室 121可具有独立的冷藏蒸发器 125和冷藏送风机 126, 冷藏蒸发器 125和冷藏送风机 126设置于位于冷藏内胆 120后壁内侧 的冷藏室送风风道 124中， 冷藏室送风风道 124具有向冷藏室 121送风的冷 藏室送风口。
进一步特别地， 再次参见图 1， 压机舱位于冷却室 135的后下方， 使得 冷却室 135上方的冷冻室 131无需再为压机舱让位， 冷冻室 131可为一个规 整的矩形空间， 便于放置体积较大不易分割的物品， 解决无法在最下方冷冻 室 131放置较大物品的痛点。
进一步特别地， 如图 3和图 4所示， 压机舱内配置有沿横向依次间隔分 布的压缩机 104、 散热风机 106及冷凝器 105。
在一些实施例中， 如图 4所示， 压机舱的后壁与压缩机 104对应的板段 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， 如图 3和图 4所示， 冰箱 100的底壁限定有横 向排布的临近冷凝器的底进风口 110a和临近压缩机 104的底出风口 110b， 冰箱 100在其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配置为从底进风口 110a的周围环境吸入环境空气并促使 空气先经过冷凝器 105 , 再经过压缩机 104, 之后从底出风口 110b流动至周 围环境中， 从而对冷凝器和 105压缩机 104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， 如图 4所示， 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， 如图 3和图 4所示， 冰箱 100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 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共同构成冰箱 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。
倾斜区段 114的前表面可形成有向上凸出的凸起 114a， 凸起 114a形成 有穿过孔 114al。 冰箱 100还包括排水管 （未示出） ， 排水管的一端连接在 排水口 130a处， 另一端穿过该穿过孔 114al延伸至设置在压机舱中的蒸发 皿（未标号） 中， 以将化霜水排到蒸发皿中， 蒸发皿一般位于冷凝器 105的 下方， 冷凝器 105和压缩机 104散发的热量将蒸发皿中的化霜水蒸发。
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， 冰箱 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， 冰箱 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， 通过将冰箱 100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。
在一些实施例中， 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， 横向分隔冰箱 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 110a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 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。
