以往，如专利文献1(特开2018-44687号公报)中记载的那样，已知在冷藏室内部配设有收纳容器的冰箱。其中，在冷藏室的最下部收纳有软冷冻(chilled)容器。由送风机吹送的空气经由形成在冷藏室后方侧的送风道而供给至冷藏室。另一方面，经送风道吹送的空气的一部分没有经过冷藏室，而是吹送至软冷冻容器，将冷风直接供给至肉之类的收纳物。通过这样做，使得软冷冻容器的容器内温度比冷藏室的室内温度更低，例如为0℃左右。这样就可以保存收纳在软冷冻容器中的肉等食品。Conventionally, as described in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2018-44687 ), there is known a refrigerator in which a storage container is disposed inside a refrigerator compartment. Among them, a soft-frozen (chilled) container is accommodated in the lowermost part of the refrigerator compartment. The air blown by the blower is supplied to the refrigerator compartment through the air duct formed on the rear side of the refrigerator compartment. On the other hand, part of the air blown through the air duct does not pass through the refrigerator compartment, but is blown to the soft freezer, and cold air is directly supplied to storage items such as meat. By doing so, the temperature inside the container of the soft freezer is lower than the indoor temperature of the refrigerator, for example, about 0°C. This makes it possible to preserve foods such as meat stored in the soft freezer container.
然而，在前述专利文献1中记载的冰箱中，从小冷藏室的低温化和恒温化的角度来看还有改善的余地。However, in the refrigerator described in the aforementioned Patent Document 1, there is still room for improvement from the viewpoint of lowering the temperature and maintaining the temperature of the small refrigerator compartment.
具体地，藉由通过冷却室冷却的空气流入来冷却小冷藏室。此外，冷却了小冷藏室的空气经由小冷藏室附近返回冷却室。另一方面，在冷却了整个冷藏室的高温空气返回冷却室时，由于会通过小冷藏室附近，因此返回的空气会使小冷藏室升温。这样就存在妨碍小冷藏室的低温化和恒温化的问题。Specifically, the small refrigerator compartment is cooled by inflow of cooled air through the cooling compartment. In addition, the air that cooled the small refrigerating room returns to the cooling room via the vicinity of the small refrigerating room. On the other hand, when the high-temperature air that has cooled the entire refrigerating room returns to the cooling room, since it passes near the small refrigerating room, the returned air heats up the small refrigerating room. In this way, there is a problem of preventing lowering of the temperature and constant temperature of the small refrigerator.

此外，在本发明的冰箱中，所述返回风道被形成为所述隔热层与板部件的间隙，从所述隔热层的主面突出的凸状部抵接所述板部件，所述凸状部的截面呈大致舟形。In addition, in the refrigerator of the present invention, the return air passage is formed as a gap between the heat insulating layer and the plate member, and the convex portion protruding from the main surface of the heat insulating layer contacts the plate member, so The cross-section of the convex portion is roughly boat-shaped.
此外，在本发明的冰箱中，所述第一小冷藏室是软冷冻室，所述第二小冷藏室是蔬菜室，通过了所述返回风道的所述空气被吹送至所述蔬菜室，冷却了所述软冷冻室的所述空气返回所述冷却室。Furthermore, in the refrigerator of the present invention, the first small refrigerator compartment is a soft freezer compartment, the second small refrigerator compartment is a vegetable compartment, and the air passing through the return air duct is blown to the vegetable compartment. , the air that has cooled the soft freezer compartment is returned to the cooling compartment.
此外，在本发明的冰箱中，所述第一小冷藏室是软冷冻室，所述第二小冷藏室是蔬菜室，所述冰箱还包括配设在所述蔬菜室内部的蔬菜室收纳容器，所述隔热层配设在所述软冷冻室与所述蔬菜室之间，所述返回风道的后端配设在比所述蔬菜室收纳容器的后端更后方侧。In addition, in the refrigerator of the present invention, the first small refrigerator compartment is a soft freezer compartment, the second small refrigerator compartment is a vegetable compartment, and the refrigerator further includes a vegetable compartment storage container disposed inside the vegetable compartment. The heat insulation layer is disposed between the soft freezer compartment and the vegetable compartment, and the rear end of the return air duct is disposed on the rear side of the rear end of the vegetable compartment storage container.
本发明的冰箱包括：冷藏室；冷却室，其中通过冷却器来冷却吹送至所述冷藏室的空气；第一小冷藏室，其在所述冷藏室的内部分隔而成；第二小冷藏室，其在所述冷藏室的内部分隔而成，并配设在所述第一小冷藏室的下方；以及分隔壁，用于分隔所述第一小冷藏室和所述第二小冷藏室；其中，所述分隔壁具有供冷却了所述冷藏室的空气返回所述冷却室的返回风道、以及配设在所述返回风道与所述第一小冷藏室之间的隔热层。根据本发明的冰箱，能够有效地达成第一小冷藏室的低温化和恒温化。具体地，由于供冷却了冷藏室的空气返回的返回风道与第一小冷藏室之间设有隔热层，因此抑制了通过返回风道的返回空气使第一小冷藏室的室内温度升温。The refrigerator of the present invention includes: a refrigerating room; a cooling room in which air blown into the refrigerating room is cooled by a cooler; a first small refrigerating room partitioned inside the refrigerating room; a second small refrigerating room , which is partitioned inside the refrigerating room and arranged below the first small refrigerating room; and a partition wall for separating the first small refrigerating room and the second small refrigerating room; Wherein, the partition wall has a return air channel through which the air that has cooled the refrigerating room returns to the cooling room, and a heat insulation layer disposed between the return air channel and the first small refrigerating room. According to the refrigerator of the present invention, lowering of the temperature and constant temperature of the first small refrigerator compartment can be effectively achieved. Specifically, since a heat insulating layer is provided between the return air duct for returning the air cooled in the refrigerating room and the first small refrigerating room, the return air passing through the returning air channel is prevented from raising the indoor temperature of the first small refrigerating room. .
此外，在本发明的冰箱中，所述返回风道具有沿上下方向延伸的纵向风道和沿水平方向延伸的横向风道，所述纵向风道的上端在所述冷藏室露出、并且下端与所述横向风道相连，所述纵向风道与所述横向风道相连的连接部的转角处呈弯曲面。根据本发明的冰箱，通过将返回风道的纵向风道与横向风道相连的连接部的转角处制成弯曲面，能够降低返回风道内部的风道阻力。由此，能够使空气良好地循环，并高效地冷却冷藏室。In addition, in the refrigerator of the present invention, the return air duct has a vertical air duct extending in the vertical direction and a horizontal air duct extending in the horizontal direction, the upper end of the longitudinal air duct is exposed in the refrigerator compartment, and the lower end is connected to the refrigerator compartment. The transverse air ducts are connected, and the corners of the joints between the longitudinal air ducts and the transverse air ducts are curved. According to the refrigerator of the present invention, by making the corner of the connecting portion connecting the longitudinal air duct and the horizontal air duct of the return air duct into a curved surface, the air duct resistance inside the return air duct can be reduced. Thereby, air can be circulated favorably and the refrigerator compartment can be cooled efficiently.
此外，在本发明的冰箱中，所述返回风道被形成为所述隔热层与板部件的间隙，从所述隔热层的主面突出的凸状部抵接所述板部件，所述凸状部的截面呈大致舟形。根据本发明的冰箱，由于将形成在返回风道处的凸状部制成舟形 形状，因此能够抑制凸状部对空气流动的妨碍。In addition, in the refrigerator of the present invention, the return air passage is formed as a gap between the heat insulating layer and the plate member, and the convex portion protruding from the main surface of the heat insulating layer contacts the plate member, so The cross-section of the convex portion is roughly boat-shaped. According to the refrigerator of the present invention, since the convex portion formed in the return air duct is formed in a boat shape, it is possible to suppress the obstruction of the air flow by the convex portion.
此外，在本发明的冰箱中，所述第一小冷藏室是软冷冻室，所述第二小冷藏室是蔬菜室，通过了所述返回风道的所述空气被吹送至所述蔬菜室，冷却了所述软冷冻室的所述空气返回所述冷却室。根据本发明的冰箱，由于将冷却了冷藏室的温度较高的空气吹送至蔬菜室，因此能够使蔬菜室保持在适宜温度。另一方面，由于冷却了软冷冻室的空气是与冷藏室不同的路径吹送至蔬菜室的，因此能够抑制蔬菜室被过度冷却。Furthermore, in the refrigerator of the present invention, the first small refrigerator compartment is a soft freezer compartment, the second small refrigerator compartment is a vegetable compartment, and the air passing through the return air duct is blown to the vegetable compartment. , the air that has cooled the soft freezer compartment is returned to the cooling compartment. According to the refrigerator of the present invention, since the high-temperature air that has cooled the refrigerator compartment is blown to the vegetable compartment, it is possible to keep the vegetable compartment at an appropriate temperature. On the other hand, since the air which cooled the soft freezer is blown to the vegetable compartment through a route different from that of the refrigerator compartment, excessive cooling of the vegetable compartment can be suppressed.
此外，在本发明的冰箱中，所述第一小冷藏室是软冷冻室，所述第二小冷藏室是蔬菜室，所述冰箱还包括配设在所述蔬菜室内部的蔬菜室收纳容器，所述隔热层配设在所述软冷冻室与所述蔬菜室之间，所述返回风道的后端配设在比所述蔬菜室收纳容器的后端更后方侧。根据本发明的冰箱，由于返回风道的后端配设在比蔬菜室收纳容器的后端更后方侧，因此能够抑制来自冰箱的空气直接流入蔬菜室收纳容器内部，并且能够抑制蔬菜室收纳容器的内部被过度冷却。In addition, in the refrigerator of the present invention, the first small refrigerator compartment is a soft freezer compartment, the second small refrigerator compartment is a vegetable compartment, and the refrigerator further includes a vegetable compartment storage container disposed inside the vegetable compartment. The heat insulation layer is disposed between the soft freezer compartment and the vegetable compartment, and the rear end of the return air duct is disposed on the rear side of the rear end of the vegetable compartment storage container. According to the refrigerator of the present invention, since the rear end of the return air passage is arranged on the rear side of the rear end of the vegetable compartment storage container, it is possible to prevent the air from the refrigerator from directly flowing into the vegetable compartment storage container, and it is possible to prevent the vegetable compartment storage container from entering the vegetable compartment storage container. The interior is overcooled.

The blower port 44 is a through hole for communicating the air introduction part 41 and the storage part 42 shown in FIG. 1 . In addition, as shown in FIG. 3B , the blower port 44 is also formed on the right end side of the top surface of the box-shaped storage portion 43 . By forming air outlets 44 on the right and left sides of the top surface of the box-shaped storage portion 43 , more air can be blown from the air introduction portion 41 shown in FIG. 1 to the storage portion 42 .
图4A是从前侧上方看分隔壁21的立体图。图4B是从前侧下方看分隔壁21的立体图。如图1所示，分隔壁21是用于上下间隔开软冷冻室20和蔬菜室30的壁状部件。FIG. 4A is a perspective view of the partition wall 21 viewed from the upper front side. FIG. 4B is a perspective view of the partition wall 21 viewed from the front lower side. As shown in FIG. 1 , the partition wall 21 is a wall member for partitioning the soft freezer compartment 20 and the vegetable compartment 30 up and down.
如图4A所示，上表面开口35是形成在分隔壁21的上表面的开口。上表面开口35是形成为大致矩形的开口，在前后方向上形成在分隔壁21的中间部。沿左右方向形成多个上表面开口35。如后文描述的，上表面开口35是供来自冷藏室12的返回空气进入的开口。As shown in FIG. 4A , the upper surface opening 35 is an opening formed in the upper surface of the partition wall 21 . The upper surface opening 35 is an opening formed in a substantially rectangular shape, and is formed in an intermediate portion of the partition wall 21 in the front-rear direction. A plurality of upper surface openings 35 are formed in the left-right direction. As described later, the upper surface opening 35 is an opening through which return air from the refrigerating compartment 12 enters.
前表面部34构成分隔壁21的前表面部分，呈平坦面。The front surface portion 34 constitutes a front surface portion of the partition wall 21 and has a flat surface.
透明板40由嵌入分隔壁21的前方部分的玻璃板等形成。参考图1，由于具有透明板40，因此在隔热门18处于打开状态时，用户可以经由分隔壁21的前方部分看到并确认贮藏在蔬菜室30中的蔬菜之类的贮藏物。也就是说，用户不用将蔬菜室30向身前拉出即可看到并确认蔬菜室30的内部。The transparent plate 40 is formed of a glass plate or the like embedded in the front portion of the partition wall 21 . Referring to FIG. 1 , since the transparent plate 40 is provided, the user can see and confirm vegetables and the like stored in the vegetable compartment 30 through the front portion of the partition wall 21 when the insulating door 18 is opened. That is, the user can see and confirm the inside of the vegetable compartment 30 without pulling the vegetable compartment 30 forward.
在此，参考图3A，软冷冻室20的后侧面部分可以由此处未图示的多管路罩构成。进一步地，软冷冻室20的右侧面部分也可以由此处未图示的内胆112 构成。Here, referring to FIG. 3A , the rear side portion of the soft freezer 20 may be constituted by a multi-pipe cover not shown here. Furthermore, the right side part of the soft freezer compartment 20 may also be comprised of the inner liner 112 which is not shown here.
如图4B所示，下表面开口36是分隔壁21的下表面的后方部分开口的部位。下表面开口36配设在分隔壁21的后端部。此外，沿左右方向形成多个下表面开口36。如后文描述的，下表面开口36是向蔬菜室30排出空气的部位。As shown in FIG. 4B , the lower surface opening 36 is a portion where the rear portion of the lower surface of the partition wall 21 is opened. The lower surface opening 36 is provided at the rear end portion of the partition wall 21 . In addition, a plurality of lower surface openings 36 are formed in the left-right direction. As will be described later, the lower surface opening 36 is a portion for discharging air to the vegetable compartment 30 .
图5是示出软冷冻室20和其附近的侧方截面图。FIG. 5 is a side sectional view showing the soft freezer 20 and its vicinity.
分隔壁21的后方部分具有供冷却了冷藏室12的空气返回冷却室115的返回风道22和配设在返回风道22与软冷冻室20之间的隔热层23。The rear portion of the partition wall 21 has a return duct 22 through which the air that has cooled the refrigerating compartment 12 returns to the cooling compartment 115 , and a heat insulating layer 23 arranged between the return duct 22 and the soft freezer compartment 20 .
返回风道22具有沿上下方向延伸的纵向风道24和沿横向方向延伸的横向风道25。就纵向风道24而言，其上端在冷藏室12露出，并且其下端与横向风道25相连。纵向风道24形成在软冷冻室20的前端侧的下方。此外，纵向风道24的上端是图4A所示的上表面开口35。横向风道25是形成在隔热层23下方的空洞，连接到分隔壁21的后端为止。返回风道22的后端是图4B所示的下表面开口36。此外，下表面开口36形成在比贮藏容器33的后面更后方侧。The return air duct 22 has a longitudinal air duct 24 extending in the vertical direction and a transverse air duct 25 extending in the lateral direction. As for the longitudinal air duct 24 , its upper end is exposed in the refrigerator compartment 12 , and its lower end is connected with the transverse air duct 25 . The longitudinal air duct 24 is formed below the front end side of the soft freezer compartment 20 . In addition, the upper end of the longitudinal air duct 24 is an upper surface opening 35 shown in FIG. 4A . The horizontal air duct 25 is a cavity formed under the heat insulating layer 23 and is connected to the rear end of the partition wall 21 . The rear end of the return air duct 22 is a lower surface opening 36 shown in FIG. 4B . In addition, the lower surface opening 36 is formed on the rear side than the rear surface of the storage container 33 .
纵向风道24的下端部与横向风道25的前端部相连的连接部的转角处26呈弯曲面。通过这样做，在从冷藏室12吹送到蔬菜室30的空气从纵向风道24流动至横向风道25时，通过作为弯曲面的转角处26而得到良好的引导。The corner 26 of the connecting portion where the lower end of the longitudinal air duct 24 is connected to the front end of the transverse air duct 25 is a curved surface. By doing so, when the air blown from the refrigerator compartment 12 to the vegetable compartment 30 flows from the vertical air duct 24 to the horizontal air duct 25, it is well guided by the corner 26 which is a curved surface.
隔热层23例如由聚氨酯泡沫塑料等制成，形成分隔壁21的上方部分。换言之，隔热层23配设在返回风道22与软冷冻室20之间，抑制返回风道22与软冷冻室20的热交换。进一步地，隔热层23配设在软冷冻室20与蔬菜室30之间，还抑制软冷冻室20与蔬菜室30的热交换。The heat insulating layer 23 is made of, for example, polyurethane foam or the like, and forms an upper portion of the partition wall 21 . In other words, the heat insulation layer 23 is arranged between the return air duct 22 and the soft freezing compartment 20 to suppress heat exchange between the return air duct 22 and the soft freezing compartment 20 . Furthermore, the heat insulation layer 23 is arrange|positioned between the soft freezer compartment 20 and the vegetable compartment 30, and also suppresses the heat exchange between the soft freezer compartment 20 and the vegetable compartment 30.
分隔壁21的后方侧形成有用于冷却了软冷冻室20的空气返回冷却室115的软冷冻室返回风道38。冷却了软冷冻室20的空气在经由软冷冻室返回风道38之后吹送至蔬菜室30。The rear side of the partition wall 21 is formed with a soft freezer return air duct 38 for returning the air cooled by the soft freezer 20 to the cooling room 115 . The air which cooled the soft freezer compartment 20 is blown to the vegetable compartment 30 after passing through the soft freezer return duct 38 .
在本实施例的冰箱10中，经由送风道118吹送至冷藏室12的空气在经由蔬菜室30之后返回前述冷却室115。具体地，冷却了冷藏室12的空气经由形成在分隔壁21内部的返回风道22而导入到蔬菜室30，并且冷却了蔬菜室30的空气返回前述冷却室115。In the refrigerator 10 of the present embodiment, the air blown into the refrigerator compartment 12 through the air duct 118 returns to the cooling compartment 115 after passing through the vegetable compartment 30 . Specifically, the air that cooled the refrigerating compartment 12 is introduced into the vegetable compartment 30 through the return air duct 22 formed inside the partition wall 21 , and the air that cooled the vegetable compartment 30 returns to the aforementioned cooling compartment 115 .
在此，在返回风道22内部流通的空气的温度例如为4℃左右。另一方面，配设在返回风道22的正上方的软冷冻室20的室内温度例如为-3℃。由此，在返回风道22内部流通的返回空气可能会不小心使软冷冻室20升温，恐怕会使 贮藏在软冷冻室20中的肉之类的被贮藏物的新鲜度下降。Here, the temperature of the air flowing through the return air duct 22 is, for example, about 4°C. On the other hand, the indoor temperature of the soft freezer compartment 20 arranged directly above the return duct 22 is, for example, -3°C. Thus, the return air circulating inside the return air passage 22 may inadvertently heat up the soft freezer 20, which may reduce the freshness of stored items such as meat stored in the soft freezer 20.
在本实施例中，在返回风道22与软冷冻室20之间配设有隔热层23。由此，限制了在返回风道22内部流通的温度较高的返回空气与软冷冻室20的温度较低的室内空气的不小心的热交换，从而能够抑制软冷冻室20的室内温度上升。In this embodiment, a heat insulation layer 23 is provided between the return air duct 22 and the soft freezer compartment 20 . In this way, inadvertent heat exchange between the high-temperature return air flowing through the return air duct 22 and the low-temperature room air in the soft freezer compartment 20 is restricted, and an increase in the indoor temperature of the soft freezer compartment 20 can be suppressed.
此外，作为从分隔壁21向蔬菜室30吹出空气的送风口的下表面开口36形成在比贮藏容器33的后端部更后方侧。由此，从下表面开口36向蔬菜室30吹出的空气不会直接导入贮藏容器33内部，而是从周边冷却贮藏容器33。由此，贮藏在贮藏容器33内部的蔬菜等能够得到恰当的贮藏。Moreover, the lower surface opening 36 which is an air blowing port which blows air from the partition wall 21 to the vegetable compartment 30 is formed in the rear side rather than the rear end part of the storage container 33. As shown in FIG. Accordingly, the air blown from the lower surface opening 36 to the vegetable compartment 30 is not directly introduced into the storage container 33, but cools the storage container 33 from the periphery. Thereby, vegetables and the like stored inside the storage container 33 can be properly stored.
参考图6A和图6B来进一步详述分隔壁21的结构。图6A是从下方看分隔壁21的分解立体图，图6B是从上方看下方板部件272的立体图。The structure of the partition wall 21 is further described in detail with reference to FIGS. 6A and 6B . FIG. 6A is an exploded perspective view of partition wall 21 seen from below, and FIG. 6B is a perspective view of lower plate member 272 seen from above.
分隔壁21具有上方板部件271、隔热层23和下方板部件272。换言之，分隔壁21是用上方板部件271和下方板部件272夹入隔热层23的结构。The partition wall 21 has an upper plate member 271 , a heat insulating layer 23 , and a lower plate member 272 . In other words, the partition wall 21 has a structure in which the heat insulating layer 23 is sandwiched between the upper plate member 271 and the lower plate member 272 .
上方板部件271由合成树脂板形成，从上方盖住隔热层23。The upper plate member 271 is formed of a synthetic resin plate and covers the heat insulating layer 23 from above.
隔热层23是由聚氨酯泡沫塑料等制成的大致板状的部件。在隔热层23的下表面形成有凸状部28。在隔热层23的下表面，以阵列状形成多个凸状部28。The heat insulating layer 23 is a substantially plate-shaped member made of urethane foam or the like. A convex portion 28 is formed on the lower surface of the heat insulating layer 23 . On the lower surface of the heat insulating layer 23, a plurality of convex portions 28 are formed in an array.
下方板部件272由合成树脂板形成，从下方盖住隔热层23。图5所示的返回风道22被形成为隔热层23与下方板部件272的间隙。The lower plate member 272 is formed of a synthetic resin plate and covers the heat insulating layer 23 from below. Return air duct 22 shown in FIG. 5 is formed as a gap between heat insulating layer 23 and lower plate member 272 .
由于凸状部28的下表面与下方板部件272的上表面抵接，从而确定了形成在隔热层23的下表面和下方板部件272的上表面处的返回风道22的厚度。Since the lower surface of the convex portion 28 is in contact with the upper surface of the lower plate member 272 , the thickness of the return air duct 22 formed at the lower surface of the heat insulating layer 23 and the upper surface of the lower plate member 272 is determined.
此外，凸状部28的截面形状呈按照返回风道22内部的空气流动的大致舟形。在此，“舟形”是指较长方向上的头尾像船的船头一样纤细地立起的形状。由于凸状部28呈大致舟形，因此能够抑制凸状部28对空气流动的妨碍。进一步地，由于凸状部28呈大致舟形，因此能够对在横向风道25中流通的空气进行整流。Moreover, the cross-sectional shape of the convex part 28 is substantially a boat shape according to the flow of the air inside the return air duct 22 . Here, "boat shape" refers to a shape in which the head and tail in the longer direction stand up slenderly like the bow of a ship. Since the convex portion 28 is substantially boat-shaped, it is possible to suppress the hindrance of the air flow by the convex portion 28 . Furthermore, since the convex part 28 is substantially boat-shaped, it is possible to rectify the air flowing through the horizontal air duct 25 .
以上是对与本实施例相关的冰箱10的说明。根据本实施例，能够取得以下记载的主要效果。The above is the description of the refrigerator 10 related to the present embodiment. According to this embodiment, the main effects described below can be obtained.
具体地，参考图5，由于供冷却了冷藏室12的空气返回的返回风道22与软冷冻室20之间设有隔热层23，因此抑制了通过返回风道22的返回空气使软冷冻室20的室内温度升温。由此，贮藏在软冷冻室20中的鱼或肉的新鲜度能够保持例如达10天以上。此外，由于软冷冻室20的下方的间隔板变得没有必 要，因此能够简化冰箱10的整体结构。Specifically, with reference to FIG. 5 , since an insulating layer 23 is provided between the return air duct 22 and the soft freezer compartment 20 for the air that has cooled the refrigerating chamber 12 to return, the return air passing through the return air duct 22 is restrained from causing soft freezing. The indoor temperature of the chamber 20 is raised. Thereby, the freshness of the fish or meat stored in the soft freezer 20 can be maintained, for example, for 10 days or more. In addition, since the partition plate below the soft freezer compartment 20 becomes unnecessary, the overall structure of the refrigerator 10 can be simplified.
进一步地，参考图5，通过将返回风道22的纵向风道24与横向风道25相连的连接部的转角处26制成弯曲面，能够降低返回风道22的内部的风道阻力。由此，空气能够良好地循环，并且能够高效地冷却蔬菜室30。Further, with reference to FIG. 5 , by making the corner 26 of the connecting portion connecting the longitudinal air duct 24 and the transverse air duct 25 of the return air duct 22 into a curved surface, the internal air duct resistance of the return air duct 22 can be reduced. Thereby, air can be circulated favorably, and the vegetable compartment 30 can be efficiently cooled.
进一步地，参考图6，由于将形成在返回风道22处的凸状部28制成舟形形状，因此能够抑制凸状部28对空气流动的妨碍。Further, referring to FIG. 6 , since the convex portion 28 formed at the return air duct 22 is made into a boat shape, it is possible to suppress hindrance of the air flow by the convex portion 28 .
进一步地，参考图5，由于冷却了冷藏室12的温度较高的空气被吹送至蔬菜室30，因此能够使蔬菜室30保持在在适宜温度。另一方面，由于冷却了软冷冻室20的空气是经其他路径吹送至蔬菜室30的，因此能够抑制蔬菜室30被过度冷却。Further, referring to FIG. 5, since the high-temperature air which cooled the refrigerating room 12 is blown to the vegetable room 30, it is possible to keep the vegetable room 30 at an appropriate temperature. On the other hand, since the air which cooled the soft freezer compartment 20 is blown to the vegetable compartment 30 through another path, excessive cooling of the vegetable compartment 30 can be suppressed.
进一步地，参考图5，由于返回风道22的后端配设在比贮藏容器33的后端更后方侧，因此能够抑制来自冰箱10的空气直接流入贮藏容器33内部，并且能够抑制贮藏容器33内部被过度冷却。Further, with reference to FIG. 5 , since the rear end of the return air duct 22 is arranged on the rear side than the rear end of the storage container 33 , it is possible to prevent the air from the refrigerator 10 from directly flowing into the storage container 33 , and it is possible to prevent the storage container 33 from The interior is overcooled.
本发明不限于前述实施例，此外，在不脱离本发明的主旨的情况下，可以有各种变更实施方式。此外，前述各实施例可以彼此组合。The present invention is not limited to the foregoing embodiments, and various modifications can be made without departing from the gist of the present invention. Furthermore, the foregoing embodiments may be combined with each other.
