Description

冰箱 技术领域
本发明涉及冰箱，特别地涉及包括多个储藏室的冰箱。
背景技术
在一般的冰箱中，在隔热箱体的内部形成有冷蔵室等储藏室，该储藏室为了冷却保存储藏的被储藏物而通过冷却循环被冷却，使得成为合适的温度区域。各储藏室通过对由冷冻循环冷却的空气送风，冷蔵室和蔬菜室被冷却到冷蔵温度区域，冷冻室被冷却到冷冻温度区域。
被冷却到冷蔵温度区域的冷蔵室和蔬菜室与被冷却到冷冻温度区域的冷冻室由包含聚氨酯树脂的隔热隔间材料划分。另一方面，冷蔵室和蔬菜室均为冷蔵温度区域的储藏室，因此作为划分冷蔵室与蔬菜室的分隔部件，采用树脂板等隔热性低的部件。相关结构的冰箱例如记载于专利文献1(日本特开2018-44746号公报)。
然而，在上述专利文献1所记载的发明中，根据从储藏室取出食品等被储藏物时的便利性的考虑，存在改善的余地。
具体而言，例如在由拉出式的隔热门封闭的蔬菜室的情况下，如果不将隔热门朝向前方与容纳容器一起拉出，则不能确认储藏在蔬菜室的内部的蔬菜等的量、种类、新鲜度等。而且，如果不将隔热门朝向前方与容纳容器一起拉出，则也不能取出储藏在蔬菜室的蔬菜等。
发明内容
本发明是鉴于上述情况而完成的，其目的在于，提供一种冰箱，使用者通过打开上方侧的储藏室的隔热门，打开滑动部，能够将储藏在下方侧的储藏室的被储藏物取出。
本发明的冰箱，其包括：形成于隔热箱体的内部的第1储藏室；形成于所述隔热箱体的内部且位于所述第1储藏室的下方的第2储藏室；对所述第1储藏室的前方开口封闭的第1隔热门；对所述第2储藏室的前方开口封闭的第2隔热门；以及划分所述第1储藏室与所述第2储藏室的分隔部，所述分隔部包括开口部和以能够滑动的状态对所述开口部封闭的滑动部。
此外，本发明的冰箱，还包括固定机构，当所述滑动部被向后方推入时，该固 定机构固定所述滑动部的位置。所述固定机构包括杠杆和卡合部，所述杠杆的中部旋转连接于所述分隔部，所述卡合部形成在所述滑动部的上表面，所述杠杆的前端部配置有弹簧，所述弹簧对杠杆的前端部的一侧施力，所述卡合部沿着所述杠杆移动到所述杠杆的后表面与卡合部抵接，以保持所述滑动部的打开状态。所述杠杆构造为沿着前后方向延伸的棒状部件，所述杠杆的后端部分且接合所述卡合部的一侧设置为朝向后方向向该侧倾斜的倾斜部。
此外，本发明的冰箱，还包括解除机构，该解除机构伴随着所述第1隔热门的关闭动作，解除所述固定机构对所述滑动部的固定。所述解除机构包括配置在所述隔热门的下端的突起部，所述隔热门关闭，所述突起部将所述杠杆的前端部向另一侧推压，所述杠杆旋转以使所述杠杆的后表面与所述卡合部分离。
此外，本发明的冰箱，还包括突出机构，在所述滑动部为打开状态的情况下，该突出机构成为突出状态，在所述滑动部为关闭状态的情况下，该突出机构成为非突出状态，在所述突出机构为所述突出状态的情况下，所述突出机构阻止所述第1隔热门的关闭动作。所述隔热门的下端配置有突起部，所述突出机构从所述分隔部的前部的上表面突出，所述突起部与所述突出机构抵接以阻止所述隔热门的关闭动作。所述突出机构包括突出部位、弹簧和旋转部，所述突出部位从所述分隔部的前部的上表面突出，所述弹簧配置在所述突出部位的下方并对突出部位向上方施力，所述旋转部的前端部与所述突出部位卡合，所述滑动部能够将所述旋转部向下按压，所述卡合部随着被向下方拉下，所述突出部位克服弹簧的作用力下降，所述突出部位与所述突出部错开以允许所述隔热门的关闭。
此外，本发明的冰箱，还包括引导部，该引导部以能够沿着前后方向移动的方式引导所述滑动部，所述引导部被配置成朝向前方而向下方倾斜。所述引导部的后方端部配置有弹簧和抵接部，所述弹簧是对抵接部朝向前方施力的施力部，所述抵接部的后端与弹簧连接，当滑动部从关闭状态向打开状态转移时，所述弹簧对滑动部朝向前方施力。
本发明的冰箱，其包括：形成于隔热箱体的内部的第1储藏室；形成于所述隔热箱体的内部且所述第1储藏室的下方的第2储藏室；对所述第1储藏室的前方开口封闭的第1隔热门；对所述第2储藏室的前方开口封闭的第2隔热门；以及划分所述第1储藏室与所述第2储藏室的分隔部，所述分隔部包括开口部和以能够滑动的状态对所述开口部封闭的滑动部。因此，根据本发明的冰箱，使用者通过打开第1储藏室的第1隔热门，打开滑动部，能够取出储藏在第2储藏室的被储藏物。具体 而言，在分隔部形成有滑动部，由此保持将第2隔热门封闭的状态，打开第1隔热门，使滑动部为打开状态，能够从第2储藏室取出储藏物。因而，能够提高使用者的便利性。
此外，本发明的冰箱，还包括固定机构，当所述滑动部被向后方推入时，该固定机构固定所述滑动部的位置。因此，根据本发明的冰箱，通过利用固定机构固定被推入的滑动部的位置，能够防止滑动部不小心移动到前方而堵塞开口部。
此外，本发明的冰箱，还包括解除机构，该解除机构伴随着所述第1隔热门的关闭动作，解除所述固定机构对所述滑动部的固定。因此，根据本发明的冰箱，通过关闭第1隔热门，能够利用解除机构解除固定机构对滑动部的固定，解除机构，能够使滑动部半自动地为关闭状态。
此外，本发明的冰箱，还包括突出机构，在所述滑动部为打开状态的情况下，该突出机构成为突出状态，在所述滑动部为关闭状态的情况下，该突出机构成为非突出状态，在所述突出机构为所述突出状态的情况下，所述突出机构阻止所述第1隔热门的关闭动作。因此，根据本发明的冰箱，在突出机构为突出状态的情况下，突出机构阻止第1隔热门的关闭动作，由此能够防止滑动部保持打开状态，第1隔热门关闭，冷却温度区域不同的第1储藏室与第2储藏室不小心地连通。
此外，本发明的冰箱，还包括引导部，该引导部以能够沿着前后方向移动的方式引导所述滑动部，所述引导部被配置成朝向前方而向下方倾斜。因此，根据本发明的冰箱，引导部朝向前方向下方倾斜，由此能够沿着倾斜的引导部使滑动部自闭。

具体实施方式
以下，根据附图，详细说明本发明的实施方式的冰箱10。在以下的说明中，原则上，对同一部件标注相同的标号，省略重复的说明。而且，在以下的说明中，适当使用上下前后左右的各方向，但左右表示从前方观察冰箱10时的左右。此外，在本实施方式中，作为冰箱10，示例了包括冷冻温度区域和冷蔵温度区域的储藏室的冰箱，但冰箱10也可以是仅包括冷冻温度区域的储藏室冰箱，或者仅包括冷蔵温度区域的储藏室的冰箱。
图1是从前方左侧观察本发明的实施方式的冰箱10的立体图。冰箱10包括隔热箱体11和形成在隔热箱体11的内部的储藏室。作为储藏室，包括作为第1储藏室的冷蔵室12、作为第2储藏室的蔬菜室121以及冷冻室13。冷蔵室12的前方开口由作为旋转式的第1隔热门的隔热门18封闭。此外，蔬菜室121的前方开口由作为拉出式的第2隔热门的隔热门19封闭。而且，冷冻室13的前表面开口由拉出式的隔热门20和隔热门21封闭。
图2是冰箱10的侧面截面图。参照图2，隔热箱体11构成为包括：外壳111，其弯曲加工成规定形状，由钢板构成，内胆112，其配置在与外壳111分离的内侧，由合成树脂板构成；以及隔热材料113，其填充在外壳111与内胆112之间。
隔热箱体11的内部的储藏室从上方划分为冷蔵室12、蔬菜室121和冷冻室13。冷蔵室12是储藏生鲜食品或饮料等的冷蔵温度区域的储藏室。蔬菜室121是容纳有蔬菜或果物等的冷蔵温度区域的储藏室。蔬菜室121的室内温度也存在被设定得比冷蔵室12的室内温度高一些的情况。冷冻室13是容纳有冷冻食品或冰等的冷冻温度区域的储藏室。
分隔部24划分冷蔵室12与蔬菜室121。此外，通过将分隔部24的前方部分呈大致矩形形状地开口，形成开口部25。开口部25由能够沿前后方向滑动的滑动部26封闭。滑动部26由玻璃等透明板部件构成。使用者不将隔热门19向前方拉出，打开隔热门18，经由透明的滑动部26，就能够视觉辨认储藏在蔬菜室121的蔬菜等被储藏物。关于滑动部26的结构等，后面参照图4等叙述。
在蔬菜室121容纳有容纳容器17。容纳容器17以能够滑动的方式配置在内胆112的内部，以使得与隔热门19一起被拉出。
蔬菜室121与冷冻室13由填充有聚氨酯等隔热材料的隔热壁23划分。
在冷冻室13的里侧划分形成有冷却室115，在冷却室115容纳有蒸发器116。在冷却室115的内部且蒸发器116的上方配置有送风机15。此外，在冷却室115的上方连接有送风道118。在隔热箱体11的后部下端划分形成有机械室14，在机械室14配置有压缩机22。蒸发器116和压缩机22与未图示的冷凝器和膨胀单元一起形成冷冻循环。在冷却室115中，由蒸发器116冷却的空气通过旋转的送风机15的送风力被送风到送风道118，进而，被吹出到冷蔵室12和蔬菜室121。由蒸发器116冷却的空气的一部分经由形成于冷却室115前方的开口，也被送风到冷冻室13。
在冷却室115的内部且蒸发器116的下方配置有除霜加热器117。除霜加热器117是通过通电而发热的加热器，除霜过程中，通过通电而发热，利用产生的热融化蒸发器116的霜。因除霜而产生的除霜水在此到达未图示的蒸发皿，通过与高温的压缩制冷剂进行热交换而蒸发。
图3是滑动部26为打开状态时的冰箱10的侧面截面图。在此，在分隔部24的内部，通过使滑动部26向后方侧滑动，将开口部25设为不被滑动部26覆盖的打开状态。通过将滑动部26设为打开状态，使用者不将隔热门19向前方拉出，即，使蔬菜室121保持关闭状态，而使隔热门18旋转打开，使滑动部26向后方滑动，将手从开口部25插入蔬菜室121，能够取出蔬菜等被储藏物。
图4(A)是示出滑动部26和引导部30的立体图，图4(B)是局部放大示出滑动部26的关键部位的立体图。
参照图4(A)，滑动部26主要包括滑动框部31、滑动透明部32、滚轮34。
滑动框部31由合成树脂构成，是外缘呈大致矩形状的框材。
滑动透明部32嵌入滑动框部31的中央开口，由玻璃板或強化塑料板材构成。
壁部33是使滑动框部31的前方部分沿着左右方向呈壁状地突出的部位。通过使用者将壁部33朝向后方按压，滑动部26向后方滑动。
滚轮34以能够旋转的方式安装于滑动框部31的四角。
引导部30配置在滑动部26的左方侧和右方侧，装配至上述的分隔部24。引导部30的左右方向内侧的面开口，滚轮34经由该开口部，插入引导部30的内部。引导部30被配置成朝向前方而向下方倾斜。通过这样，即使使用者不操作，因滑动部26的自重，滑动部26沿着引导部30向前方移动。即，滑动部26包括自闭功能。
滑动框部31的前方部分可以由比重比其他部分大的材料、例如不锈钢等金属构成。通过这样，能够使滑动部26的重心向前方移动，促进前述的自闭功能。
参照图4(B)，卡合部35在滑动框部31的上表面形成，在其前端附近且右端附 近。卡合部35是使滑动框部31的上表面局部向上方突起的部位，在此，呈大致圆柱形状。卡合部35是用于使滑动部26的位置固定的部位，参照图7等说明其功能。
图5(A)是示出关闭状态的滑动部26等的截面图，图5(B)是示出弹簧37等的放大截面图，图5(C)是示出滑动部26等的立体图。
参照图5(A)，在分隔部24的内部容纳有引导部30，利用引导部30，引导滑动部26向前后方向移动。此外，在引导部30的后方端部配置有弹簧37和抵接部36。
参照图5(B)，弹簧37是对抵接部36朝向前方施力的施力部，配置在引导部30的后表面与抵接部36之间。抵接部36的后端与弹簧37连接，前端部分呈大致半圆形状。如后面记述，当滑动部26从关闭状态向打开状态转移时，对滑动部26朝向前方施力。
参照图5(C)，如上所述，通过将分隔部24的前方部分呈大致矩形形状开口而形成的开口部25由滑动部26封闭。通过这样，能够划分成形成于分隔部24的上方的冷蔵室12和形成于分隔部24的下方的蔬菜室121。
图6(A)是示出打开状态的滑动部26等的截面图，图6(B)是示出弹簧37等的放大截面图，图6(C)是示出滑动部26等的立体图。
参照图6(A)，使用者将形成于滑动部26的前端的壁部33朝向后方推入，由此滑动部26在引导部30的内部朝向后方滑动。由此，开口部25成为未被滑动部26覆盖的打开状态。
参照图6(B)，在打开状态的情况下，滑动部26的后端部分将抵接部36向后方推，弹簧37沿前后方向被压缩，对滑动部26朝向前方施力。
参照图6(C)，滑动部26向分隔部24的前端侧滑动，由此，开口部25成为未被滑动部26覆盖的打开状态，冷蔵室12与蔬菜室121经由开口部25连通。此外，使用者能够经由开口部25从蔬菜室121取出蔬菜等食品。
图7(A)是示出滑动部26为关闭状态时的固定机构27的俯视图，图7(B)是示出滑动部26从关闭状态转移到打开状态时的固定机构27的俯视图，图7(C)是示出滑动部26为打开状态时的固定机构27的俯视图。
参照图7(A)，在滑动部26的右方侧配置有固定机构27。固定机构27包括当滑动部26被向后方推入时固定滑动部26的位置的功能。固定机构27包括杠杆38和卡合部35。固定机构27在打开状态下固定滑动部26的位置，当从打开状态向关闭状态转移时不固定滑动部26的位置。
参照图7(B)，详述构成固定机构27的杠杆38的结构。
杠杆38是沿着前后方向延伸的大致棒状的部件，由合成树脂构成。杠杆38的大致中央部通过支承部39，相对于作为冰箱10的主体侧的分隔部24，以能够旋转的方式连接。通过这样，杠杆38能够以支承部39为旋转中心顺时针和逆时针旋转。
杠杆38的后端部分且右方侧的侧面设为朝向后方向右方倾斜的倾斜部40。此外，如后面记述，杠杆38的后端面呈与滑动部26的卡合部35抵接的大致平坦的抵接面。此外，在杠杆38的前端部形成有朝向上方呈大致板状地突出的抵接部41。而且，在杠杆38的前端部配置有弹簧42。
弹簧42对杠杆38的前端部朝向左方施力。结果，克服使杠杆38逆时针旋转的作用力进行作用。因此，抵接部41被向左方施力，杠杆38的后方部分被向右方施力。
而且，图7(B)示出滑动部26从关闭状态转移到打开状态的状态。若滑动部26被朝向后方推入，则形成于滑动部26的前方右端的卡合部35也朝向后方移动。此时，卡合部35一边被由弹簧42施力的杠杆38的倾斜部40按住，一边向后方移动。
参照图7(C)，若滑动部26被推入到里侧，则滑动部26的卡合部35配置在比杠杆38的后端靠后方的位置。杠杆38的后方侧由弹簧42朝向右方施力。因而，杠杆38的后表面配置在卡合部35的前方侧，杠杆38的后表面与卡合部35抵接。通过这样，滑动部26的卡合部35由杠杆38从前方支撑，从而保持滑动部26的打开状态。
图8(A)是示出隔热门18的下部结构的立体图，图8(B)是示出抵接部41的结构的立体图。
参照图8(A)，在隔热门18的下端配置有容纳例如塑料瓶等的收纳盒55。通过使收纳盒55的下表面局部地朝向下方突出，形成突起部43和突起部45。参照图10，如后面记述，突起部43是伴随着隔热门18的关闭动作而使滑动部26进行关闭动作的部位。参照图12，如后面记述，突起部45是在滑动部26不能进行关闭动作时阻止隔热门18进行关闭动作的部位。
参照图8(B)，图7(B)等所示的杠杆38的抵接部41从在分隔部24的前端附近开口的开口部44朝向上方突出。
图9是示出冰箱10主体侧的抵接部41与隔热门18侧的突起部43的相关结构的立体图。若使用者欲关闭旋转式的隔热门18，则形成于隔热门18的下端的突起部43与构成后述的解除机构28的抵接部41抵接。
图10(A)、图10(B)、图10(C)和图10(D)是示出伴随着隔热门18的关闭动作的利用解除机构28的滑动部26的关闭动作的仰视图。
参照图10(A)，解除机构28是伴随着隔热门18的关闭动作解除固定机构27对滑动部26的固定的机构。解除机构28包括图9所示的突起部43和杠杆38。杠杆38的结构参照图7(B)等进行了说明。隔热门18为打开状态时，滑动部26的卡合部35被杠杆38的后端面推压，由此，滑动部26的位置在后方被固定，开口部25未被滑动部26覆盖。
参照图10(B)，若使用者进行隔热门18的关闭动作，则设置于隔热门18的底面的突起部43将设置于杠杆38的前端部的抵接部41向右方侧推压。如上所述，杠杆38能够将支承部39作为中心进行旋转。因而，若作为杠杆38的前端部的抵接部41被向右方侧推压，则杠杆38的后端部向左方侧摆动。
参照图10(C)，若杠杆38的后端部向左方侧振动，则杠杆38的卡合部35配置在滑动部26的比滑动框部31靠左方侧的位置。通过这样，滑动部26不再由杠杆38从前方支承，利用前述的自闭功能朝向前方滑动。此时，隔热门18将冷蔵室12封闭。
参照图10(D)，滑动部26朝向前方滑动，由此，开口部25由滑动部26覆盖。如参照图4(A)所说明的那样，引导滑动部26的引导部30朝向前方向下方倾斜。此外，如图6(B)所示，关闭状态的滑动部26被弹簧37朝向前方施力。即，滑动部26包括自闭机构。因而，即使使用者没有对滑动部26进行关闭动作，通过使用者关闭隔热门18，失去杠杆38的支承的滑动部26因自闭作用而向前方移动，从而封闭开口部25。
图11(A)和图11(B)是示出隔热门18的关闭动作被塑料瓶46阻止的状态的俯视图，图11(C)是示出该状态的立体图。
参照图11(A)，在滑动部26的打开状态下，滑动部26配置在后方，开口部25未被滑动部26覆盖。在该状态下，若使用者对隔热门18进行关闭动作，则通过图10(B)所示的解除机构28进行工作，滑动部26朝向前方移动。
参照图11(B)，例如使用者误在蔬菜室121收纳塑料瓶46等障害物时，滑动部26的关闭动作在途中被阻止。即，在塑料瓶46的上部抵接有滑动部26的前侧边，滑动部26不能封闭开口部25。此外，如果隔热门18的打开状态为一定时间以上，则通过从扬声器产生通知音，通知隔热门18为打开状态。使用者对该通知反应，取出塑料瓶46，关闭隔热门18，由此，滑动部26封堵开口部25。
参照图11(C)，塑料瓶46阻止滑动部26的前进，由此，在滑动部26的关闭动作未完成时，突出机构29从前表面部52的上表面突出。从隔热门18向下方突出的突起部45与突出机构29抵接，由此隔热门18的关闭动作被阻止。通过这样，滑动部26保持打开状态，即，冷蔵室12与蔬菜室121保持经由开口部25连通，能够防止隔热门18成为封闭状态。突出机构29的具体结构参照图12后面进行记述。
图12(A)是示出隔热门18的关闭动作被突出状态的突出机构29阻止的状况的截面图。图12(B)是示出隔热门18的关闭动作未被非突出状态的突出机构29阻止的状况的截面图。
参照图12(A)，突出机构29是以下这样的机构：在滑动部26为打开状态时成为突出状态，在滑动部26为关闭状态时成为非突出状态。此外，突出机构29为突出状态时，突出机构29阻止隔热门18的关闭动作。
具体而言，突出机构29包括突出部位47、弹簧48、旋转部49。
突出部位47是沿着上下方向延伸的棒状或板状的部件，其上部从在前表面部52的上表面开口的贯通孔54向上方突出。在突出部位47的下方配置有弹簧48，弹簧48对突出部位47向上方施力。
旋转部49是配置成能够转动的大致板状的部件，其后端部相对于分隔部24能够转动地连接，其前端部与突出部位47的中间部卡合。此外，在旋转部49的下方，配置有能够容纳旋转部49的大致盒状的容纳部50。
在开口部25未被滑动部26封闭的状态下，滑动部26未到达可动区域的前端。因而，旋转部49未被滑动部26的滚轮34压下。因此，由弹簧48施力的突出部位47向上方突出的突出量长，其上端成为与隔热门18的突起部45抵接的突出状态。因而，在该状态下，隔热门18的关闭动作被阻止。
参照图12(B)，滑动部26为了使开口部25为关闭状态，若移动到可动区域的前端，则配置在滑动部26的前端的滚轮34将旋转部49向下方按压。由此，旋转部49以旋转中心51为中心转动，卡合部53被向下方拉下。同时，突出部位47一边克服弹簧48的作用力一边下降。因而，突出部位47的上端配置在比隔热门18的突起部45的下端靠下方的位置，突出部位47不会抵接于突出部45。因而，突出机构29不会阻止隔热门18的关闭动作，使用者能够将隔热门18平滑地封闭。
通过前述的本实施方式，能够起到以下那样的主要效果。
根据本发明，参照图3，打开隔热门18，使开口部25向后方侧滑动，能够经由开口部25从蔬菜室121取出蔬菜等被储藏物。具体而言，在分隔部24形成有滑动 部26，由此保持将隔热门19封闭的状态，打开隔热门18，使滑动部26为打开状态，能够从蔬菜室121取出储藏物。因而，能够提高使用者的便利性。
而且，参照图7(C)，通过固定被固定机构27推入的滑动部26的位置，能够防止滑动部26不小心移动到前方而封闭开口部25。
而且，参照图10，通过关闭隔热门18，能够解除固定机构27对滑动部26的固定，使滑动部26半自动地为封闭状态。
而且，参照图11，在突出机构29为突出状态时，突出机构29阻止隔热门18的关闭动作，由此能够抑制滑动部26保持打开状态而隔热门18关闭，冷却温度区域不同的冷蔵室12与蔬菜室121无意间连通。
而且，参照图4(A)，引导部30朝向前方向下方倾斜，由此能够沿着倾斜的引导部30使滑动部26自闭。
以上，对本发明的实施方式进行了说明，但本发明并不限定于这些，在不脱离本发明主旨的范围内能够进行变更。此外，前述的各方式能够相互组合。
