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 131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。

而本实施例通过在储物间室的下方限定冷却室， 使得冷却室占用箱体 100的下部空 间， 抬高了冷冻室 132的高度， 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； 并且， 冷却室可为压机舱提供让位， 而冷冻室 132不再需要为压 机舱让位， 避免现有方案中冷冻室 132需要为压机舱让位而导致冷冻室 132存在异形的 问题， 从而可保证冷冻室 132的进深和存储容积。 另外， 通过在蒸发器 101的下游设置 送风风机 103 , 加速经蒸发器 101冷却后的气流向储物间室流动， 保证冰箱 10的制冷效 果。
图 5是根据本发明第二实施例的冰箱 10的冷冻内胆 130及其内部各部件的示意图， 其中， 隐去了罩板 102的顶盖 1021， 以示出送风风机 103， 图 6是根据本发明第一实施 例的冰箱 10的局部不意图。
如图 3、 图 5和图 6所示， 送风风机 103在气流流动路径上位于蒸发器 101的下游， 配置为促使经蒸发器 101冷却后的冷却气流向至少一个储物间室内流动。 送风风机 103 可为离心风机， 送风风机 103设置于冷却室中并位于蒸发器 101的后方， 且由前至后向 上倾斜地设置。 也即是说， 送风风机 103的前端低于后端， 使得送风风机 103整体呈现 为向后倾斜的姿势。 由此减小送风风机 103的布置高度， 减小送风风机 103所占的高度 空间， 从而减小冷却室所占的高度空间， 保证了冷却室上部的储物间室的存储容积。
蒸发器 101整体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， 保证冷却室上方 的冷冻室 132的存储容积。
送风风机 103包括机壳 1031和设置于机壳 1031内的叶轮 1032,机壳 1031由前至后 呈向上倾斜延伸， 其上表面形成有机壳进风口， 其后端形成有机壳出风口。 叶轮 1032的 倾斜方向与机壳 1031的倾斜方向平行， 也即是说， 叶轮 1032的旋转轴线与机壳 1031的 上表面垂直， 使得机壳 1031位于叶轮 1032后方的出风风路与叶轮 1032大致平行， 避免 送风风机 103出风处窝风， 保证送风效率， 减小气流流动噪音。
如图 6所示， 机壳 1031的上表面与竖直面的夹角卩1为 55 ° 至 70° 。 也可理解为， 叶轮 1032的旋转轴线与竖直线的夹角为 20 ° 至 35 ° ， 例如， 可为 20 ° 、 25 ° 、 30 ° 、 33 ° 或 35 ° 。 通过如此布置送风风机 103， 在减小送风风机 103所占高度空间的同时， 最大程度的减少气流流动损失， 从而在保证空间布局的紧凑性的同时， 进一步保证送风 效率。
机壳 1031的前端面与蒸发器 101的后端面的水平距离 a为 15毫米至 35毫米，例如， a可为 15毫米、 20毫米、 25毫米、 30毫米或 35毫米， 避免因送风风机 103与蒸发器 101距离过小而造成送风风机 103结霜。
第二实施例与第一实施例不同的是， 第二实施例中， 机壳 1031具有蜗形风道， 以降 低气流噪音。
冰箱 10还包括送风风道 141， 送风风道 141与送风风机 103的机壳出风口连通， 送 风风机 103促使冷却气流经送风风道 141流动至至少一个储物间室内。在第一实施例中， 冷如图 3所示， 冻内胆 130限定有位于冷却室上方的冷冻室 132和位于冷冻室 132上方 的变温室 131， 送风风道 141具有连通冷冻室 132的第一送风出口和具有连通变温室 131 的第二送风出口。 在第二实施例中， 如图 4、 图 5所示， 冷冻内胆 130仅限定有位于冷却 室上方的冷冻室 132， 送风风道 141具有连通冷冻室 132的第一送风出口。
图 7是根据本发明第二实施例的冰箱 10的局部示意图， 图 8是图 7的分解示意图。 如图 2、 图 4至图 8所示，冷却室的前侧形成有与冷冻室 132连通的至少一个前回风 入口， 以使得冷冻室 132的回风气流通过至少一个前回风入口进入冷却室中进行冷却。
冰箱 10还包括罩板 102， 罩板 102的前侧形成有前述的至少一个前回风入口。 如图 1所示， 在本发明的第一实施例中， 如图 2所示， 罩板 102的后部敞开， 罩板 102罩扣在 冷冻内胆 130的底部， 并与冷冻内胆 130的后壁、 底壁和两个横向侧壁共同限定出冷却 室， 罩板 102的前侧形成有前回风入口 102a。
在第一实施例中， 如图 6所示， 冰箱 10还包括由前至后呈阶梯状的风道盖板 139， 风道盖板 139位于罩板 102上表面的下方， 并设置于蒸发器 101 的上部。 风道盖板 139 包括由前至后依次相接的前板段 139a、 过渡板段 139c和后板段 139b， 前板段 139a与蒸 发器 101的上表面间隔设置， 以在前板段 139a与蒸发器 101上表面之间形成气流通道， 后板段 139b贴紧于蒸发器 101的上表面， 避免后板段 139b与蒸发器 101的上表面存在 间隔而导致回风气流直接向后流动而不经过蒸发器 101。
风道盖板 139与罩板 102上表面之间的空间应填充挡风泡沫 139d， 使得回风气流无 法进入风道盖板 139与罩板 102上表面之间的空间， 从而避免部分回风气流进入风道盖 板 139与罩板 102上表面之间的空间而不经过蒸发器 101。
进入冷却室的回风气流的一部分通过蒸发器 101 的前端面的前方进入蒸发器 101 中 与蒸发器 101换热， 另一部分由蒸发器 101前端面的上方进入前板段 139a与蒸发器 101 的上表面之间间隔形成的气流通道， 再向下由蒸发器 101 的上表面进入蒸发器 101 中与 蒸发器 101 换热。 由此， 使得进入冷却室的回风气流从不同方向、 不同位置进入蒸发器 101中， 提升蒸发器 101的冷却效果。
另外， 当外部环境湿度大或者蒸发器 101 的前端面异常结霜影响进风时， 回风可以 从前板段 139a与蒸发器 101的上表面之间的气流通道进入蒸发器 101中， 避免结霜影响 蒸发器 101的换热效率， 从而有效保证冰箱 10的制冷效果。
与第一实施例不同的是， 第二实施例中， 如图 4所示， 罩板 102包括位于蒸发器上 方的顶盖 1021和至少一个前盖组，每个前盖组的前侧形成有前述的至少一个前回风入口， 顶盖 1021、 该至少一个前盖组与冷冻内胆 130的后壁、 底壁和横向两个侧壁共同限定出 冷却室。
前盖组可为两个， 两个前盖组沿横向方向分布。 图 4、 图 5、 图 7、 图 8仅示出了位 于横向右侧的一个前盖组， 每个前盖组的前侧均形成有前述的至少一个前回风入口。
如图 4所示， 每个前盖组的前侧形成有两个前回风入口， 两个前回风入口分别记为 第一前回风入口 102a和第二前回风入口 102b。
如图 7和图 8所示， 每个前盖组包括前饰盖 1022和前风道盖 1023， 前饰盖 1022的 前端部 10221位于蒸发器 101的前端的前方， 前端部 10221并与蒸发器 101的前端间隔， 前饰盖 1022的前端部 10221的前壁形成有第一开口 1022a， 前饰盖 1022的前端部 10221 的后侧敞开； 前风道盖 1023 的前端部 10231位于蒸发器 101 的前端， 且前风道盖 1023 的前端部 10231 由前饰盖 1022的前端部 10221的后侧敞开处向前插入前饰盖 1022中， 以将第一开口 1022a分隔为位于下方的第一前回风入口 102a和位于上方的第二前回风入 P 102b。
具体地， 前风道盖 1023的前端部 10231的底壁与前饰盖 1022的前端部 10221的底 壁限定有与第一前回风入口 102a贯通的第一回风通道， 该第一回风通道位于蒸发器 101 的前方， 也即是说， 前风道盖 1023的前端部 10231 由前饰盖 1022的前端部 10221的后 侧敞开处向前插入前饰盖 1022中的位置使得前风道盖 1023的前端部 10231的底壁与前 饰盖 1022的前端部 10221 的底壁之间间隔， 以形成与第一前回风入口 102a贯通的第一 回风通道， 以使得经第一前回风入口 102a进入第一回风通道的至少部分回风气流由蒸发 器 101的前方进入蒸发器 101中由蒸发器 101进行冷却。
前风道盖 1023的前端部 10231位于上方的区段形成有与第二前回风入口 102b贯通 的第二开口 1023a， 且第二开口 1023a位于蒸发器 101的前上方。 顶盖 1021的下表面与 蒸发器 101的上表面间隔分布， 顶盖 1021的前端位于蒸发器 101的前端的后上方， 也即 是说， 顶盖 1021未完全遮蔽蒸发器 101的上表面的上方。 并且， 顶盖 1021的下表面与 蒸发器 101的上表面之间填充有挡风材料 （未示出） ， 如图 8所示， 顶盖 1021与蒸发器 101的上表面间隔分布形成间隔空间 102c， 该间隔空间 102c中填充有挡风材料 （图 2中 隐去了所填充的挡风材料） ， 该挡风材料可为挡风泡沬。
并且， 前风道盖 1023包括位于第二开口 1023a后上方的第一遮蔽部 10232， 第一遮 蔽部 10232的后端与顶盖 1021 的前端抵接， 以封闭蒸发器 101 的上表面上方未被顶盖 1021遮蔽的部分， 从而在第一遮蔽部 10232与蒸发器 101的上表面之间形成与第二开口 1023a、 与第二前回风入口 102b贯通的第二回风通道， 从而使得经第二前回风入口 102b 进入第二回风通道的至少部分回风气流由蒸发器 101 的上方进入蒸发器 101 中由蒸发器 进行冷却。
由于顶盖 1021与蒸发器 101 的上表面的间隔空间 102c中填充有挡风材料， 避免进 入第二回风通道的回风气流直接向后流动而不经过蒸发器 101，使得进入第二回风通道的 回风气流向下流动由蒸发器 101的上表面进入蒸发器 101中。
前饰盖 1022 包括由其前端部 10221 的后侧上缘向后上方弯折延伸的第二遮蔽部 10222， 第二遮蔽部 10222位于第一遮蔽部 10232的上方， 并延伸至与顶盖 1021的上表 面搭接， 以完全遮蔽第一遮蔽部 10232的上方， 并且， 第二遮蔽部 10222的外形与第一 遮蔽部 10232的外形适配， 以使得第二遮蔽部 10222与第一遮蔽部 10232紧密配合， 避 免漏风。
若蒸发器 101 的前端面未结霜或结霜量较小而使得蒸发器 101 的前端面仍然可通过 气流， 则冷冻室 132的回风气流的一部分经第一前回风入口 102a进入第一回风通道， 冷 冻室的回风气流的一部分经第二前回风入口 102b进入第二回风通道， 进入第一回风通道 的部分气流由蒸发器 101 的前方 （也即是由蒸发器 101的前端面） 进入蒸发器 101 中， 由蒸发器 101进行冷却，进入第一回风通道的另一部分气流再向上流动至第二回风通道， 由第二回风通道再向下流动进入蒸发器 101 中， 从而使得部分回风气流由蒸发器 101 的 前方进入蒸发器 101 中， 部分回风气流由蒸发器 101的上方进入蒸发器 101 中， 进而保 证回风气流与蒸发器 101的充分换热， 提升冰箱 10的制冷效果。
若蒸发器 101的前端面结霜较厚而导致气流无法进入蒸发器 101中时，则冷冻室 132 的回风气流可经位于上方的第二前回风入口 102b进入第二回风通道， 并由第二回风通道 向下流动， 由蒸发器 101的上表面进入蒸发器 101中进行冷却， 从而仍可保证冰箱 10的 制冷效果。
本实施例的冰箱 10, 通过对顶盖 1021、 前饰盖 1022和前风道盖 1023的结构进行特 别的设计， 保证了冷冻室 132的回风气流与蒸发器 101的换热效率， 提升了冰箱 10的制 冷效果； 并且， 在蒸发器 101 的前端面结霜时， 仍可保证回风气流能够进入蒸发器 101 中由蒸发器 101进行冷却，解决了现有冰箱 10因蒸发器 101结霜而导致制冷效果降低的 问题， 提升了冰箱 10的整体性能。
再次参见图 6, 本实施例的冰箱中， 箱体 100底部限定有压机舱， 且压机舱位于冷却 室的后方， 使得压机舱整体处于冷冻室 132的下方， 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。
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、 散热风机 106 和冷凝器 （未示出） 沿横向依次间隔布置在压机舱内。 箱体 100 的底壁限定有横向排布 的与冷凝器对应的底进风口和与压缩机对应的底出风口， 散热风机 106配置为从底进风 口的周围环境吸入环境空气并促使空气先经过冷凝器， 再经过压缩机， 之后从底出风口 流动至周围环境中， 从而对冷凝器和压缩机进行散热， 在蒸气压缩制冷循环中， 冷凝器 的表面温度一般低于压缩机的表面温度， 故上述过程中， 使外部空气先冷却冷凝器再冷 却压缩机。 本实施例的冰箱 10可进行嵌入式布置， 用于嵌入式橱柜， 以减小冰箱 10所占空间。 为提升冰箱 10的整体美观度和减小冰箱 10所占空间，冰箱 10后壁与橱柜的预留空间较 小， 导致了现有技术中所采用的前后进出风方式的散热效率较低， 而如果以保证散热为 前提， 必须增加冰箱 10后壁与橱柜的距离， 然而同时却带来了冰箱 10所占空间增大的 问题。
而本实施例的冰箱 10, 通过在箱体 100的底壁限定有横向排布的底进风口和底出风 口， 散热气流在冰箱 10底部完成循环， 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， 提升了散热效 率。
箱体 100的底壁的四角可设置有支撑滚轮 （为示出） ， 箱体 100通过四个支撑滚轮 放置于支撑面上， 并使得箱体 100的底壁与支撑面形成一定的空间。
在图 6所示的实施例中， 用于送风的风机仅有一个， 故为了实现冰箱的冷冻室 132、 冷藏室以及变温室内的温度均处在特定的温度段， 需要在送风风道 141 的与上述各储物 间室连通的通道内分别设置风门， 并通过控制风门的开启时间而控制各储物间室内的温 度。 而上述这种控温方式具有以下两个缺陷： 一方面， 当所有风门均打开时， 由于各储 物间室内的温度不一， 将导致送风通道的气流流动紊乱， 温度较低的储物间室内的冷却 气流易向温度较高的冷却间室内窜动， 降低了温度较低的储物间室内的降温速率。 另一 方面， 由于需要周期性的开启和关闭风门来保证各储物间室的温度参数符合要求， 故各 储物间室内的温度无法恒定， 其会在某一个范围值内进行浮动。
为了解决上述缺陷， 在一种实施例中， 如图 9-12所示， 提供了一种利用双送风风机 进行送风的解决方案。即冰箱包括第一风机 104以及第二风机 105,送风风道 141包括向 变温室送风的第一风道 1411以及向冷冻室 132送风的第二风道 1412。第一风机 104以及 第二风机 105均设置在冷却室内，而第一风机 104配置成促使冷却气流通过第一风道 1411 流向变温室， 第二风机 105配置成促使冷却气流通过第二风道 1412流向冷冻室 132。 而 冷藏室由于其降温要求不高， 故其可以利用常规的通过控制风门打开时间进行控温的方 式来降温。
冰箱的冷冻室 132与冷藏室均分别单独具有一个风机来供风使第一风道 1411以及第 二风道 1412内的冷却气流不会互窜， 防止了冷冻室 132和变温室的温度相互干扰。特别 地， 还可以通过分别控制第一风机 104和第二风机 105的送风量来持续控制变温室和冷 冻室 132内的温度， 使冷冻室 132以及变温室内的温度更加恒定。
为了使第一风机 104以及第二风机 105均能够给予对应的风道内的气流足够大的驱 动力， 以防止第一风道 1411和第二风道 1412内的气流互窜， 一种实施例中， 可以使第 一风机 104以及第二风机 105均设置于蒸发器 101的下游 （以冷却气流动流动方向来确 定上游和下游） 。 第一风机 104设置于蒸发器 101的下游可以使其更加贴近于第一风道 1411的入风口， 并使第一风机 104产生的气流尽可能的全部导向第一风道 1411， 提高对 变温室内的温度的控制精度。 同理， 第二风机 105设置于蒸发器 101的下游亦可以提高 对冷冻室 132内的温度的控制精度。 当冰箱的蒸发器 101设置于各储物间室下方时， 送风风道 141需要由下至上输送冷 却气流。 为了增强送风风机的送风效率， 不论送风风机的数量为多少， 均可以使各送风 风机沿斜向上的方向输送冷却气流。 当风机的数量为两个时， 如图 10-12 所示， 第一风 机 104以及第二风机 105可以为轴流风机， 且第一风机 104以及第二风机 105均沿冷却 气流的流动方向往斜向上的方向输送冷却气流。 具体地， 可以使第一风机 104 以及第二 风机 105的转动轴线与水平面的夹角 （即图 10中的角 a） 为 5度到 60度之间， 例如 5 度、 10度、 20度、 40度或 60度。
在一种实施例中， 如图 10所示， 冰箱的冷冻内胆 130内具有设置于冷却室上方的冷 冻室 132以及位于冷冻室 132上方的降温室 133。变温室设置于冷冻内胆 130的上方（图 10中未示出）。冷冻室 132以及降温室 133均可以由抽屉结构进行限定， 即冷冻内胆 130 内可以设置有上抽屉以及下抽屉， 上抽屉内限定的空间为降温室 133 , 下抽屉内限定的空 间为冷冻室 132。送风风道 141设置于冷冻内胆 130内的后方，且送风风道 141的各出风 口均对应位于各储物间室的后侧壁位置。
降温室 133 用于根据用户的需求对物品进行降温处理， 其温度取值范围覆盖冷冻室 132以及变温室的温度取值范围，例如，冷冻室 132内的温度取值范围处于 -22°C至 -14°C， 且变温室的温度取值范围 -18 °C至 8°C时， 降温室 133 的温度取值范围则至少为 -22°C至 8°Co 降温室 133 用于在冰箱的变温室内的物品装满的情况下充当变温室， 且在冷冻室 132内的物品装满的情况下充当冷冻室 132, 提升了冰箱的适配性， 使冰箱的使用场景更 加丰富。
当具有降温室 133时， 冰箱的送风风道 141还包括第三风道 1413 , 第一风机 104通 过第三风道 1413向降温室 133内进行送风。第三风道 1413内设置有第一调节风门 1416, 第一风道 1411内设置有第二调节风门 1415。当降温室 133用作变温室时，可以使第一调 节风门 1416以及第二调节风门 1415同时周期性地开闭， 第一风机 104同时向第一风道 141 1以及第三风道 1413内供风。当降温室用作冷冻室 132时，可以将第一调节风门 1416 开启， 并让第二调节风门 1415周期性地开闭， 第一风机 104朝第一风道 1411和第三风 道 1413 内送风， 第二风机 105向第二风道 1412送风， 此时， 降温室以及冷冻室 132内 的温度与冷却室中的蒸发器 101的温度近似相等。
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。
