Description

冰箱 技术领域
本发明涉及冰箱，尤其涉及对收纳在贮藏室中的容器吹送冷气的冰箱。
背景技术
传统的一种冰箱，在冷藏室内部配置有收纳容器，如专利文献1(特开2018-44687号公报)中记载的那样。其中，冷藏室的最下部收纳有冰鲜(chilled)容器。鼓风机吹送的冷气，经由形成在冷藏室后侧的送风路而供给至冷藏室。经送风路吹送的冷气，一部分没有经由冷藏室，而是直接吹送至冰鲜容器。通过这种方式，冰鲜容器的容器内温度比冷藏室的室内温度更低，例如在0℃左右。通过这种方式，可以以保持原本的鲜度的方式保存储存在冰鲜容器中的肉等的食品。
然而，在上述专利文献1中记载的冰箱中，就维持储存在冰鲜容器中的食品的鲜度而言，尚有改善的余地。
具体来说，为了长时间地持续保持储存在冰鲜容器中的食品的鲜度，冰鲜容器的室内温度最好在-3℃左右的低温处保持不变，使得容器内的食品不会完全冻结。然而，在为了降低冰鲜容器的室内温度而向冰鲜容器导入-15℃左右的冷气时，导入的冷气可能会直接吹到食品上，存在很难维持鲜度的问题，食品可能最终会冻结。
为了应对该问题，考虑从冰鲜容器的顶面侧进行冷却。然而，在为了确保可见性而用玻璃之类的透明部件制造冰鲜容器的顶面的情况下，出现了难以在顶面侧形成风路的问题。
发明内容
本发明是鉴于上述技术问题做出的发明，其目的在于提供能长期 持续保持储存在收纳容器中的食品的鲜度的冰箱。
本发明的冰箱，其包括：冷却室，收纳有用于冷却空气的冷却器；送风路，供冷气从所述冷却室吹送至贮藏室；收纳容器，配置在所述贮藏室的内部；以及导入口，供所述冷气导入所述收纳容器的内部；风路盖板，在所述收纳容器内部与所述导入口相对的位置处。
根据本发明的冰箱，可以长期持续保持储存在形成冰鲜室等的收纳容器中的食品的鲜度。具体而言，风路盖板配设在收纳容器内部的与导入口相对的位置，从而抑制了冷气从导入口直接吹入收纳容器的容器内。由此，贮藏在收纳容器中的肉等的食品不会直接被冷气吹到，从而能够抑制食品脱水变干。
此外，在本发明的冰箱中，其还包括隔热部件，所述隔热部件配置在所述风路盖板与所述导入口之间，并且由隔热性优于所述风路盖板的材料制成。
根据本发明的冰箱，隔热部件配置在风路盖板与导入口之间，从而抑制了冷气直接撞上风路盖板，因此可以抑制风路盖板的前表面变得朦胧不清。
此外，在本发明的冰箱中，所述隔热部件具有侧方倾斜面，所述侧方倾斜面是所述隔热部件与所述导入口相对的面，朝向侧方且向远离所述导入口的方向倾斜。
根据本发明的冰箱，通过使隔热部件的侧方端部为倾斜面，可以使从导入口导入的冷气向侧方流动。由此，能够连到收纳容器的侧方端部为止都均一地冷却，并且能够抑制冷气直接吹到收纳物上。
此外，在本发明的冰箱中，所述隔热部件具有下方倾斜面，所述下方倾斜面是所述隔热部件与所述导入口相对的面，向下且向远离所述导入口的方向倾斜。
根据本发明的冰箱，通过使隔热部件的下方端部为倾斜面，可以使 从导入口导入的冷气向下流动。由此，能够使得收纳容器从上到下都均一地冷却，并且能够抑制冷气直接吹到储存物品上。
此外，在本发明的冰箱中，其特征在于，所述收纳容器的底面设置有金属板，导入所述收纳容器的所述冷气的一部分吹到所述金属板上。
根据本发明的冰箱，冷气可以吹到配置在收纳容器的底面上的金属板上，并通过金属板来冷却被贮藏物，这样能够更有效地冷却被贮藏物。

具体实施方式
接下来基于附图来详细说明本发明的实施方案所涉及的冰箱10。在本实施方案的说明中，原则上对同一部件使用同一附图标记，并省略反复说明。此外，在接下来的说明中，使用上下前后左右的各个方向进行说明，但是左右是从前方看冰箱10的情况下的左右。
图1是从左前方看冰箱10的立体图。冰箱10具有隔热箱体11和形成在隔热箱体11内部的贮藏室。作为贮藏室，从上到下有冷藏室12和冷冻室13。冷藏室12的前方开口用旋转式的隔热门18和隔热门19封住。冷冻室13的前表面开口用隔热门20和隔热门21封住。隔热门18、隔热门19、隔热门20和隔热门21是旋转式的门，可以以左右方向的外侧端部作为旋转轴旋转。
图2是显示隔热门18、隔热门19、隔热门20和隔热门21变为开放状态的冰箱10的正面图。
冷藏室12的下部配置有收纳容器25和收纳容器26。收纳容器25和收纳容器26是由合成树脂制成的大致箱状的容器，被设置成可在前后方向上拉出。收纳容器25的内部作为被冷却至-3℃左右的温度带的冰鲜容器。收纳容器26的内部作为被冷却至2℃左右的低温保存蔬菜等的容器。收纳容器25和收纳容器26以外的部分的冷藏室12的室内温度处于例如3℃至5℃的冷藏温度区间。收纳容器26的左方侧配设有用于贮存供给至制冰机的水的给水箱24。隔热门18和隔热门19的内部侧面配置有用于保管饮料或调味料等的收纳筐17。
冷冻室13中收纳有多个收纳容器32。这里配置了呈行列状的6个收纳容器32。每个收纳容器32可沿前后方向拉出。冷冻室13的室内温 度处于例如-20℃至-18℃的冷冻温度区域。冷冻室13内部配设有图中未示出的自动制冰机。自动制冰机通过冻结从前述给水箱24供给的水来制冰。
参考图3的侧方截面图来说明冰箱10的截面结构。图3中用虚线箭头示出了关于冰箱10内部的冷气流动。
隔热箱体11由以下部分构成：外箱111，其由被弯折加工成指定形状的钢板制成；内箱112，配置在与外箱111隔开一定距离的内侧，由合成树脂板制成；以及填充在外箱111与内箱112之间的隔热材料113。
如前所述，隔热箱体11内部的贮藏室从上到下划分成冷藏室12和冷冻室13。冷藏室12和冷冻室13用隔热壁27来划分。
冷藏室12的内部在上下方向上通过多个收纳搁板15来划分。配置在冷藏室12的最下部的收纳容器26上方配置有收纳搁板152。收纳搁板152的上方配置有收纳容器25，收纳容器25的上方开口用收纳搁板151遮盖。如前所述，收纳容器26的内部用作蔬菜室，并且收纳容器25的内部用作冰鲜室。
覆盖收纳容器25内部的上表面的收纳搁板151由例如玻璃板的透明板材制成。由于收纳搁板151由透明板材制成，因此用户即使不将收纳容器25向前拉出也能透过收纳搁板151看到储存在收纳容器25中的食品。
冷冻室13的里侧形成有冷却室115，冷冻室13与冷却室115用间隔壁28划分。冷却室115内部配设有作为冷却器的蒸发器116。冰箱10的下端侧后方划分形成机械室14，机械室14中配置有压缩机22。蒸发器116和压缩机22以及这里未图示出的冷凝器和膨胀装置一起形成蒸气压缩冷冻循环。通过运行蒸气压缩冷冻循环，用蒸发器116冷却冷却室115内部的冷气，将该冷气吹送至各贮藏室，从而使各贮藏室的室内温度变为指定的冷却温度区域。
在冷却室115的内部、在蒸发器116的上方侧配置有鼓风机29。鼓风机29是轴流式风机或离心式风机，将被蒸发器116冷却的冷气向着冷藏室12和冷冻室13吹送。
在冷却室115的内部，在蒸发器116的下方配置有除霜加热器117。伴随着蒸气压缩冷冻循环的运行，会在蒸发器116的表面结出厚厚的霜。在发生这种情况时，图中未示出的控制装置会停止压缩机22，对除霜加热器117通电以使之加热，从而进行融化并去除霜的除霜运行。
形成有从冷却室115向上的送风路118。送风路118形成有作为用于将冷气吹出到冷藏室12的开口的出风口23。从出风口23向前方吹出冷气。送风路118的中间装有风路风门31，与其相关的结构在后文参考图4A描述。
如后文所述，冷气从与送风路118分开形成的风路直接送至收纳容器25。从而将收纳容器25的室内冷却至冰鲜温度区间。与其相关的结构在后文参考图8A等描述。
从出风口33吹出的冷气的一部分并非经由导入口34导入收纳容器25，而是在收纳容器25与收纳搁板152之间向前行进后流动至下方。此外，从导入口34吹出到收纳容器25内部的冷气在冷却了收纳容器25内部之后从形成在收纳容器25的前端的开口向前吹出，之后向下流动。
收纳容器26是半密闭型的收纳容器。也就是说，收纳容器26并未形成有用于积极地进行冷气的导入或排出的开口。此外，如上所述，从出风口33吹出的冷气的一部分向下在冷藏室12内部流动，从外侧将收纳容器26包围。这样，收纳容器26的容器内温度维持在比冷藏室12的代表性室内温度更低的冷藏温度区间。
由鼓风机29吹送的冷气，一部分经由作为形成在间隔壁28中的开口的送风口41而吹送至冷冻室13。冷却了配置在冷冻室13中的各容器内部的冷气，从回风口42返回冷却室115。从而将冷冻室13冷却至指 定的冷冻温度区间。
图4A是示出送风路118等的结构的正面图，并且图4B是示出冰箱10的冷藏室12以及送风路118等的正面图。
参考图4A和图4B，通过在送风路118的侧方和上端部开口而形成出风口16。通过隔热门18的冷气从出风口16吹出到冷藏室12内部。
送风路118的下方部分安装有风路风门31。用图中未示出的冷藏室12的温度传感器来检测室内温度，并通过开闭风路风门31来将冷藏室12的温度冷却至指定的冷藏温度区间。
送风路119是从送风路118的中间部分向右上方分岔出去的风路。送风路119的下部安装有风路风门30。检测收纳容器25的容器内温度的温度传感器安装在送风路119中。通过基于相关联的温度传感器检测到的检测温度，来开闭风路风门30来使收纳容器25的容器内温度变为指定的冰鲜温度区间。
参考图4B，送风路119的上端形成有出风口33和导入口34。经由送风路119向上吹送的冷气经由出风口33和导入口34直接吹送至收纳容器25。出风口33和导入口34的结构等在后文参考图5等描述。
送风路118的中间部分形成有出风口40。出风口40是在收纳搁板151的上方将在送风路118中上升的冷气吹出到冷藏室12的开口。当冷藏室12变为打开的状态时，会有收纳搁板151的表面附着有结露的情况。由于从出风口40吹送的冷气在收纳搁板151的上表面上流动，因此即使有这样的情况也能消除附着在收纳搁板151的表面上的结露。
图5是示出冷藏室12内部的配设有出风口33和导入口34的部分的侧方截面图。
出风口33是形成在隔热箱体11上的用于将在送风路119中流通的冷气吹送至收纳容器25的开口。出风口33从前方看呈大致矩形的形状，其前端配设有肋条39。肋条39是大致水平地延伸的板状部件，沿上下 方向大致等间隔地配设有多个。
导入口34通过在收纳容器25的后侧面开出大致矩形的开口而形成。导入口34被形成为比出风口33更大。具体而言，导入口34被形成为在上下方向和左右方向上比出风口33更长。也就是说，在收纳容器25被收纳在冷藏室12内部的状态下，导入口34的上端配置在比出风口33的上端更上方的位置，导入口34的下端配置在比出风口33的下端更下方的位置，导入口34的左端配置在比出风口33的左端更左侧的位置，并且导入口34的右端配置在比出风口33的右端更右侧的位置。
这样，从出风口33吹出的冷气的大部分都可以经由导入口34而导入收纳容器25的容器内，并且能有效地冷却收纳容器25的容器内。
在导入口34处，从前方侧安装有风路盖板35，并且从后侧安装有后面部件38。
风路盖板35配置在收纳容器25内部与导入口34相对的位置。风路盖板35由大致盖状地形成的合成树脂板制成。风路盖板35的具体结构等在后文参考图6和图7描述。
后面部件38是从后侧安装到收纳容器25的导入口34的合成树脂制成的部件，具备用于冷气流通的开口。后面部件38的具体结构在后文参考图6和图7描述。
隔热部件36配置在风路盖板35与导入口34之间。隔热部件36由隔热性优于风路盖板35的材料制成，例如由泡沫聚苯乙烯之类的泡沫树脂制成。隔热部件36的具体结构在后文参考图6和图7描述。
收纳容器25的底面设置有由例如铝或不锈钢等制成的金属板37。储存在收纳容器25中的食品设置在金属板37的上表面上。
前述风路盖板35和后面部件38经由导入口34而嵌合。此外，风路盖板35在内置有隔热部件36的状态下与后面部件38嵌合。
图6是从前方看风路盖板35等的情况的分解立体图。图7是从后方 看风路盖板35等的情况的分解立体图。尽管这里未图示出，但是在隔热部件36与后面部件38之间配置有过滤装置。可以采用例如收纳有除臭珠的袋状无纺织布、或者形成蜂巢形状的滤纸等作为过滤装置。通过配置过滤装置，可以对冷气进行除臭，此外还可以抑制粉尘等侵入收纳容器25。
参考图6，后面部件38是具有向前的开口的大致盖状的部件。后面部件38的前表面周围形成有外侧壁部383。外侧壁部383是后面部件38的外周部向前呈壁状突出的部位。外侧壁部383是与风路盖板35嵌合的部位。
上方开口部381和下方开口部382是形成在后面部件38的左右方向上大致中央的开口。冷气经由上方开口部381和下方开口部382而导入收纳容器25内部。
如图7所示，上方开口部381被形成为多个狭缝。通过这样的结构，可以防止用户的手进入上方开口部381的里侧而与前述过滤装置接触。此外，如图6所示，上方开口部381被壁状部位围住。具体而言，上方开口部381被开口壁部384、开口壁部385和开口壁部386围住。开口壁部384、开口壁部385和开口壁部386是从后面部件38的前表面向前竖立设置的部位。通过这样的结构，这里未图示出的过滤装置可以配置在由开口壁部384、开口壁部385和开口壁部386围住的区域。
如图7所示，下方开口部382被形成为一个大致矩形形状的开口。下方开口部382形成在上方开口部381的下方。
如图6所示，隔热部件36内置于通过后面部件38和风路盖板35形成的空间中。参考图7，隔热部件36的作为与前述导入口34相对的面的后表面具有平坦面364、侧方倾斜面361、侧方倾斜面362和下方倾斜面363。
平坦面364是形成在隔热部件36的后表面中的在左右方向上处于中 央的上方部分的平坦的面。平坦面364大体上相对于经由上方开口部381导入的冷气的流动垂直。
侧方倾斜面361是向右而向前倾斜的面。侧方倾斜面361形成在隔热部件36的右侧边与平坦面364之间。侧方倾斜面361是使从上方开口部381导入的冷气向右流动的部位。
侧方倾斜面362是向左且向前倾斜的面。侧方倾斜面362形成在隔热部件36的左侧边与平坦面364之间。侧方倾斜面362是使从上方开口部381导入的冷气向左流动的部位。
下方倾斜面363是使隔热部件36与导入口34相对的面向下且向前倾斜的部位。下方倾斜面363形成在隔热部件36的下侧面与平坦面364之间。下方倾斜面363是使从下方开口部382导入的冷气向下流动的部位。
如图7所示，风路盖板35是在后方开口的大致盖状的部件。风路盖板35具有侧方开口部351、侧方开口部352和下方开口部353。
侧方开口部351通过在风路盖板35的右侧面上开口而形成。沿隔热部件36的侧方倾斜面361流动的冷风从侧方开口部351吹出到前述收纳容器25内部。
侧方开口部352通过在风路盖板35的左侧面上开口而形成。沿隔热部件36的侧方倾斜面362流动的冷风从侧方开口部352吹出到前述收纳容器25内部。
下方开口部353通过在风路盖板35的下侧面上开口而形成。沿隔热部件36的下方倾斜面363流动的冷风从下方开口部353吹出到前述收纳容器25内部。
这里，风路盖板35的上表面没有形成开口部。也就是说，冷气不会从风路盖板35向上吹出。参考图3，通过这种方式，避免了作为从上方罩住收纳容器25的玻璃板的收纳搁板151变得朦胧不清。
图8A是示出从导入口34吹出到收纳容器25的冷气的流动的侧方截面图。
首先，被图3所示的冷却室115中的蒸发器116冷却的冷气利用鼓风机29的吹送力在送风路119中向上吹送。在送风路119中流动的冷气从出风口33向前吹出。此时，冷气是沿肋条39大致水平地吹出的。
此后，冷气从出风口33吹出到收纳容器25。如前所述，收纳容器25的导入口34被形成为比出风口33更大。由此，从出风口33吹出的冷气的大部分经由导入口34而导入收纳容器25的容器内。这样就可将收纳容器25的容器内温度冷却至-3℃±1℃的温度区间。
导入口34处配置有前述开口壁部385。开口壁部385向前向下倾斜。从而使从出风口33吹出的冷气的一部分向下流动，可以有效地冷却如后文所述的金属板37。
如前所述，风路盖板35的后方安装有隔热部件36。由此，从导入口34导入收纳容器25的冷气撞上隔热部件36的后表面，而不会吹到风路盖板35上。由此，避免了风路盖板35被冷气直接冷却，并且可以避免风路盖板35的前表面变得朦胧不清或出现结露。假使风路盖板35的前表面变得模糊不清或出现结露，恐怕会在视觉上感觉不干净。在本实施方案中，通过避免该朦胧不清或结露，可以提高清洁感。
从出风口33吹出的冷气的一部分撞到形成在隔热部件36的前表面下方部分的下方倾斜面363上，于是被引导向下方。此后，冷气经由风路盖板35的下方开口部353向下侧向前行进，并撞到金属板37的上表面上。此后，冷气沿金属板37的上表面向前行进。通过这种方式，最终借助于金属板37来冷却收纳容器25的内部空间和被贮藏物。
图8B是与图8A的A-A截面线相对应的截面，是示出沿隔热部件36的冷气流动的上方截面图。从出风口33导入至导入口34的冷气的一部分在撞到平坦面364上之后沿着侧方倾斜面361和侧方倾斜面362向 左和向右行进，并从收纳容器25的侧面吹出到收纳容器25的容器内。
图9A是示出从风路盖板35吹出的冷气的流动的立体图。图9B是示出收纳容器25内部的冷气流动的立体图。图9A中用虚线箭头示出了冷气流动，并且图9B中用涂白的箭头示出了冷气流动。
参考图9A，被图8B所示的侧方倾斜面361引导向右侧的冷气经由风路盖板35的侧方开口部351吹出到收纳容器25的容器内。此外，被图8B所示的侧方倾斜面362引导向左侧的冷气经由风路盖板35的侧方开口部352吹出到收纳容器25的容器内。进一步地，被图8A所示的下方倾斜面363引导向下方的冷气经由下方开口部353吹到收纳容器25的容器内。
参考图9B，冷气从风路盖板35向左和向右吹出，可以从周围均一地冷却收纳容器25的内部。此外，冷气从风路盖板35向下吹出。这样就直接冷却金属板37，可以有效地冷却放置在金属板37上的食品。进一步地，可以均一地冷却收纳容器25，直到其下方端部为止。
另一方面，冷气不会从风路盖板35向前吹出。由此，-15℃左右的冷气不会直接吹到贮藏在收纳容器25中的食品等上，可以避免食品的表面脱水变干或冻结，并且可以避免食品等的鲜度降低。进一步地，冷气不会从风路盖板35向上吹出。由此，冷气不会吹到图3所示的收纳搁板151上，这样，即使不专门在收纳搁板151上安装加热器之类的装置，也能避免变得朦胧不清或出现结露。
本发明不限于上述实施方案，相反，在不脱离本发明的主旨的范围内，可能有各种各样的实施变型。
具体而言，通过设置吹出到形成在收纳容器25内部的冰鲜室的冷气的风量、与冷藏室12分开设置的专用风路和风路风门，可以将冰鲜容器的温度控制在-3±1℃。通过这种方式，可以减小贮藏在收纳容器25中的食品的温度变化，减少水分的蒸发量，从而使得能够保持更好的鲜度。
