Description

制冰机 技术领域
本发明涉及制冰机，尤其涉及配备于冰箱冷冻室中的制冰机。
背景技术
以往，在冷冻室等内部配备有用于贮存冰块的贮冰容器。
例如专利文献1(日本特开2021-96047号公报)中记载了将箱体的储藏间室的一部分作为制冰室，将制冰装置放置于该制冰室中并利用该制冰装置来进行制冰。此外，根据供水方式的不同，制冰机被分为自动向制冰装置供水的自动式制冰机和手动向制冰装置供水的手动式制冰机。
使用手动式制冰机时，将冷冻室的一部分划分为制冰区域，将制冰装置放置在该制冰区域内部。制冰装置能够在制冰区域内部沿前后方向自由拉出。在进行制冰时，用户将存有水的制冰装置滑动到制冰区域并收纳在那里。存在制冰装置中的水冻结后，用户将制冰装置从冷冻室的制冰区域内取出，并扭转制冰装置(或以类似动作)来使冰块脱离。
制冰装置放置于制冰区域内后，制冰装置的各制冰凹槽沿着阵列状排列，并且制冰装置整体呈扁平的长方体形状。这样，当制冰装置收纳在冷冻室的制冰区域中时，制冰装置靠近冷气进风口一侧的冷却温度与背离冷气进风口一侧的冷却温度不同。这样就导致制冰装置存在冻结不均匀的情况，因此增加了制冰所需的时间。
发明内容
因此，本发明的目的在于提供一种能够缩短制冰所需时间的制冰机。
一种制冰机，设置于冷冻室内，所述制冰机包括制冰机主体和制冰装置，
所述制冰机主体包括用于容纳所述制冰装置的容纳部以及设置于进风口与所述制冰装置之间的冷气导入部，所述进风口用于导出经蒸发器冷却的冷气；
所述制冰装置具有多个用于存放制冰用水的制冰凹槽，
所述冷气导入部具有：
将所述冷气的一部分引导向所述制冰装置的上方的上导流部，以及
将所述冷气的一部分引导向所述制冰装置的下方的下导流部。
进一步地，通过对所述收纳部进行开孔而形成开孔部。
进一步地，所述上导流部在朝向接近所述制冰装置的方向上具有向上方倾斜的倾斜面；
所述下导流部在朝向接近所述制冰装置的方向上具有向下方倾斜的倾斜面。
进一步地，两个所述上导流部位于所述下导流部的相对两侧。
进一步地，在从所述进风口吹出所述冷气的方向为第一方向并且相对于所述第一方向正交的方向为第二方向的情况下；
两个所述上导流部在所述第二方向上的宽度大于所述下导流部在所述第二方向上的宽度。
进一步地，两个所述上导流部在所述第二方向上的宽度之和小于所述下导流部在所述第二方向上的宽度。
进一步地，两个所述上导流部在所述第二方向上的宽度之和等于所述下导流部在所述第二方向上的宽度。
进一步地，上导流部前端的水平高度大于或者等于制冰装置上端的水平高度。
进一步地，下导流部前端的水平高度小于或者等于制冰装置下端的水平高度。
发明效果
与现有技术相比，能够缩短制冰所需的时间。具体地，可以在制冰装置的上方和下方形成冷气流动，因此可以从上方和下方有效地冷却贮存在制冰装置中的制冰用水。由此，可以均匀地冷却并冻结贮存在制冰装置的各制冰凹槽中的制冰用水。

箱体11是冰箱10的主体。箱体11由以下各部分构成：前表面具有开孔部的钢板制的外壳111；配设于外箱111的内侧并与其保持间隙的内胆112，内胆112由合成树脂制成；以及用于发泡充填外箱111与内胆112之间间隙的隔热材料113，隔热材料113由发泡聚氨酯制成。
在储藏间室内部划分出冷藏室12、冷冻室13和蔬菜室14。最上层的冷藏室12和位于其下层的冷冻室13用间室壁20间隔开。冷冻室13和位于其下层的蔬菜室14用间室壁21间隔开。间室壁20和间室壁21具有与箱体11同样的隔热构造。
制冰机30设置在冷冻室13内部，用于制造冰块。制冰机30位于冷冻室13的顶部，配置为手动型制冰机。关于制冰机30的细节描述可参考后文中图2及以后的各图。在制冰时，用户首先拉出门体16，再将制冰机30的制冰装置31(后文中有相关描述)取出。然后，用户将制冰装置31的制冰凹槽311注满水(后文中有相关描述)。再然后，用户将注满水的制冰装置31放回制冰机30。此后，注满水的制冰装置31在冷冻室13内部被冻结，从而在制冰凹槽311内形成冰块。然后，当用户需要冰块时打开门体16，从制冰机30上取下制冰装置31，并将冰块从制冰装置31上脱离。
箱体11的前表面设置有开口，并且对应于冷藏室12、冷冻室13和蔬菜室14的所述开口处，分别设置有可自由开闭地门体15、门体16、门体17，其各自具有与箱体11大致同等的隔热构造。门体15以其侧边附近的上下部分可自由旋转的方式支承在箱体11上。门体16和门体17以其可向冰箱10前方自由拉出的方式支承在箱体11上。
在冷冻室13的后方侧形成有与冷冻室13相连的用于供给冷气的供冷风道22。供冷风道22形成于隔板与冷冻室13的内壁之间，隔板由合成树脂制成，所述隔板形成有供冷气流动的进风口34。
在供冷风道22的后部通过隔板而形成有蒸发室18。在蒸发室18内部配设有用于对在储藏间室内循环的冷气进行冷却的蒸发器19。
蒸发器19通过例如翅片管式蒸发器来实现。蒸发器19通过冷媒配管而与压缩机25、冷凝器(未示出)和毛细管(未示出)等连接。这样就构成了蒸汽压缩式冷 冻循环回路。另外，压缩机25、冷凝器的一部分和用于向冷凝器送风的散热风扇(未示出)等配设在形成于冰箱10的下部后方的机械室中。
在蒸发室18的上部形成有与供冷风道22相连的开口，即出风口，该出风口安装有用于使冷气循环的送风机24。送风机24配置为轴流风机，来实现将被蒸发器19冷却后的冷气从蒸发室18流向各储藏间室。此外，在蒸发室18的下部形成有用于冷气从冷冻室13返回蒸发室18的开口，即回风口。
在冷藏室12的后方，经过由合成树脂制成的隔板划分后，形成用于向冷藏室12供给冷气的供冷风道23。供冷风道23与供冷风道22相连，同时经由进风口与冷藏室12相连。
冰箱10具有供冷风道(未示出)和回风风道(未示出)等，供冷风道与冷藏室12和蔬菜室14相连并用于向蔬菜室14供给冷气，回风风道与冷藏室12和蔬菜室14以及蒸发室18相连并用于冷气从冷藏室12和蔬菜室14返回蒸发室18。此外，供冷风道22和供冷风道23等也可以设有风门(未示出)等，其用于控制向储藏间室供给的冷气的流量，从而准确地维持储藏间室内部的温度。
利用具有上述结构的冰箱10，将冷藏室12和蔬菜室14冷却至指定的冷藏温度区域，并且将冷冻室13冷却至指定的冷冻温度区域。
图2A是制冰机30的立体示意图，并且图2B是制冰机30的正视图的剖面视图。
参考图2A，制冰机30由制冰机主体38和制冰装置31构成。制冰机主体38采用合成树脂材料通过一体成型的方式制成，并且具有收纳部32和冷气导入部33。制冰装置31收纳在制冰机主体38的收纳部32中。关于制冰机主体38结构的描述可参考后文中的图3B。
制冰装置31用于贮存制冰用水并进行制冰的容器。制冰装置31收纳在收纳部32内部，可沿前后方向自由拉出。关于制冰装置31细节的描述可参考后文中的图3A。
参考图2B，收纳部32配置为板状结构，用于收纳制冰装置31的部件。具体地，收纳部32具有：下表面部321；自下表面部321的左侧端部向上竖直延伸的侧面部322；以及自下表面部321的右侧端部向上竖直延伸的侧面部323。
在收纳部32的下表面部321、侧面部322和侧面部323与制冰装置31之间具有间隙。侧面部322与侧面部323相隔的距离大于制冰装置31的宽度，从而在侧面部322和侧面部323与制冰装置31之间形成间隙。此外，通过在制冰装置31的下表面形成沿前后方向延伸的肋条，通过肋条来间隔下表面部321与制冰装置31，使二者 之间形成间隙。
具体地，制冰装置31的下表面与收纳部32的下表面部321之间形成有间隙261。制冰装置31的左端部与收纳部32的侧面部322之间形成有间隙262。制冰装置31的右端部与收纳部32的侧面部323之间形成有间隙263。进一步地，制冰装置31的上方形成有间隙264。
从图1所示的进风口34吹出的冷气在前述间隙261、间隙262、间隙263和间隙264中流通。进一步描述可参考后文中的图5。
图3A是示出制冰机30的制冰装置31的立体示意图。
制冰装置31整体呈扁平的长方体形状，形成有多个用于贮存制冰用水的制冰凹槽311。制冰凹槽311从上方看大致呈正方形形状的凹状结构，多个制冰凹槽311按阵列方式进行排列。制冰装置31的前端部向下倾斜以形成拉出部312。用户通过手指从下方勾住拉出部312的方式，来实现向前方拉出制冰装置31。制冰凹槽311采用合成树脂材料制成，并通过不同形状的凸模来改变形状。
图3B是示出制冰机主体38的立体示意图。制冰机主体38的收纳部32与冷气导入部33沿着前后方向排布。收纳部32用于收纳前述制冰装置31。冷气导入部33用于向制冰装置31导入所吹送的冷气。
如图1所示，冷气导入部33位于进风口34与前述制冰装置31之间的部位。冷气导入部33具有下表面部333、侧面部334和侧面部335。下表面部333是相对于水平面大致平行的面。侧面部334自下表面部333的左端向上竖直延伸。侧面部335自下表面部333的右端向上竖直延伸。冷气导入部33进一步细节的描述可参考后文中的图4。
对收纳部32进行开孔后而形成开孔部37。具体地，在下表面部321、侧面部322和侧面部323的前端附近设置多个开孔部37。通过设置开孔部37，使得冷气吹向收纳部32后，其中一部分能够通过开孔部37向收纳部32外部泄漏，从而加速收纳部32内外冷气的流通，继而缩短制冰所需的时间。
图4是制冰机主体38的立体示意图。上导流部331和下导流部332沿着前后方向排列在冷气导入部33上。
上导流部331形成于下表面部333的前端部，上导流部331沿着自后向前的方向逐渐凸起于下表面部333。上导流部331分别形成在冷气导入部33的左端部和右端部。在上导流部331之间形成下导流部332。通过设置上导流部331和下导流部332，可以将向前方吹送的冷气引导向前述制冰装置31的上方和下方。
下导流部332形成于下表面部333的前端部，下导流部332沿着自后向前的方向逐渐向下倾斜。下导流部332形成于冷气导入部33左右方向的中间位置。通过这样做，可以将向前方吹送的冷气引导向前述制冰装置31的下方。
两个上导流部331相对设置于下导流部332的左右两侧。利用该结构，可以良好且均匀地将冷气吹送至前述制冰装置31的上方和下方，并且还可以使得制冰装置31的每个制冰凹槽311获得均匀的冷量从而同时进行冻结。
这里对上导流部331和下导流部332的宽度进行说明。以从进风口34吹出冷气的方向为第一方向D1，并且以相对于第一方向D1正交的方向为第二方向D2。这里，前后方向是第一方向D1，并且左右方向是第二方向D2。
作为一个示例，上导流部331在第二方向D2上的宽度可以比下导流部332在第二方向D2上的宽度更长。
具体地，左侧的上导流部331的宽度为A1，右侧的上导流部331的宽度为A2，并且下导流部332的宽度为B。然后，A1和A2加起来的长度可以比B更长。通过这样做，可以优先对前述制冰装置31的上方吹送冷气，从而可以从上方冻结贮存在制冰装置31的各制冰凹槽311内的制冰用水。
另一方面，A1与A2加起来的长度可以比B短。通过这样做，可以优先对前述制冰装置31的下方吹送冷气，从而可以从下方冻结贮存在制冰装置31的各制冰凹槽311内的制冰用水。
此外，A1与A2加起来的长度也可以与B相等。通过这样做，可以对前述制冰装置31的上方和下方均等地吹送冷气，并可以从上方和下方同时冻结贮存在制冰装置31的各制冰凹槽311内的制冰用水。
图5是制冰机30获取冷气时的侧面剖视图的立体示意图。
被前述蒸发器19冷却的空气从进风口34吹向前方。
从进风口34吹出的冷气中，一部分沿着上导流部331流动而形成上冷却风35。上冷却风35形成于制冰装置31的上方。上冷却风35从上方冷却贮存于制冰装置31的各制冰凹槽311内的制冰用水。此后，上冷却风35从收纳部32的前端开孔流向外部，即流向冷冻室13的下部。上冷却风35形成于制冰机30内部的左右两侧。图5中，以虚线示出上冷却风35。此外，如图3B所示，上冷却风35的一部分从侧面部322和侧面部323上的开孔部37流向制冰机30外部。
从进风口34吹出的冷气中，一部分沿着下导流部332流动而形成下冷却风36。下冷却风36形成于制冰装置31的下方。下冷却风36从下方冷却贮存于制冰装置31 的各制冰凹槽311内的制冰用水。此后，下冷却风36从收纳部32的前端开孔流向外部，即流向冷冻室13的下部。图5中，以虚线示出下冷却风36。此外，如图3B所示，下冷却风36的一部分从下表面部321上的开孔部37流向制冰机30外部。
此外，上导流部331前端的水平高度大于或者等于制冰装置31上端的水平高度。通过这样做，可以使在制冰装置31的上方的上冷却风35的流动顺畅。进一步地，下导流部332前端的水平高度小于或者等于制冰装置31下端的水平高度。通过这样做，可以使在制冰装置31的下方的下冷却风36的流动顺畅。
如上所述，通过使冷气在制冰装置31内部良好地流通，可以减小制冰装置31前后的温度差。此外，上冷却风35在制冰装置31的上表面侧流向左右两侧，进一步地，下冷却风36在制冰装置31的下表面侧在左右方向上流向中央，从而减小了制冰装置31的左侧区域与右侧区域的温度差。由此，可以在形成于制冰装置31中的全部制冰凹槽311中均等地进行制冰用水的冻结，并且可以缩短制冰所需的时间。
根据本实施形态可以实现下面记载的主要效果。
参考图5，由于可以形成向制冰装置31的上方和下方的冷气流动，因此可以从上方和下方有效地冷却贮存在制冰装置31中的制冰用水。由此，可以均匀地冷却并冻结贮存在制冰装置31的各制冰凹槽311内的制冰用水。
参考图3B，由于导入的冷气从收纳部32的开孔部37从制冰机30漏到外部，因此可以抑制制冰装置31的上方和下方的冷气淤积，并且可以更有效地冻结贮存在制冰装置31中的制冰用水。
参考图4，可以沿构成上导流部331和下导流部332的倾斜面向制冰装置31的上方和下方顺畅地吹送冷气。
如图5所示，可以通过上冷却风35和下冷却风36从上方和下方均等地冷却制冰装置31。
参考图4，可以沿上导流部331吹送较多的冷气，并且可以有效地冷却并冻结贮存在制冰凹槽311内的制冰用水。
本发明不限于前述实施形态中限定的内容，此外，在不脱离本发明的要旨的范围内可实施各种改变。此外，前述形态可以彼此组合。
