Description

用于冰箱的蒸发皿及冰箱 技术领域
本发明涉及冷藏冷冻技术，特别是涉及一种用于冰箱的蒸发皿及冰箱。
背景技术
在日常生活中，人们主要利用冰箱来冷藏和储存食品，大多数冰箱的蒸发器位于后背，风道出风和回风方向杂乱，不利于降温和保鲜。近年来，蒸发器位于内胆底部的底置冰箱被研发推广，这种蒸发器布局方式可实现风道出风和回风平行，即平行流制冷。
目前使用一个蒸发器底置的布局已在法式冰箱上得到了很好的应用，但对于宽度较宽的冰箱，需要采用两个底置蒸发器才能实现较好的效果。例如T型冰箱和对开冰箱等，这种具有两个底置蒸发器的冰箱通常会有两个或以上的排水管进入压缩机仓连接到蒸发皿上，这两个排水管往往会被压缩机仓内部的风机风筒隔断，其中冷冻室排水管和蒸发皿位于一侧，变温室排水管位于另一侧，由于风机风筒的隔断，导致变温室排水管无法连接到原有蒸发皿。
为了解决上述技术问题，现有用于双排水系统的蒸发皿多通过风机下部连通，即风机位于蒸发皿上部，这种方式会造成压缩机仓整体高度抬高，进而造成内胆中储物空间的减少。
发明内容
本发明的目的在于提供一种具有适用于具有双排水系统冰箱的蒸发皿以及冰箱。
本发明的一个进一步的目的是提高压缩机仓内的结构布局的合理性。

进一步地，所述冰箱还包括：

风筒组件，用于安装所述散热风机，所述风筒组件沿所述箱体的进深方向延伸，以将所述压缩机仓内的空间分隔成横向并排的两部分；且
所述第一容置区域和所述第二容置区域分别位于所述风筒组件的横向两侧，所述压缩机和所述第二容置区域位于所述风筒组件在横向上的同一侧。
进一步地，所述风筒组件包括位于后侧的风机安装部和连接在所述风机安装部前侧的密封隔板；且所述密封隔板上开设有避让缺口，所述蒸发皿的连接流道穿设在所述避让缺口中。

本发明的有益效果是：
冰箱的压缩机在压缩机仓内位于风筒组件的一侧，必然会占用该侧较大的空间，导致该侧剩余空间较小，不便于设置蒸发皿。正因为如此，现有技术中的蒸发皿通常设置在远离压缩机的一侧。然而，本发明的蒸发皿特别地设有两个容置区域，以分别接收从冰箱的两个排水管中排出的冷凝水。并且，两个容置区域通过连接流道连通，第二容置区域的高度高于第一容置区域，由此，第二容置区域接收到的冷凝水可通过连接流道流入第一容置区域，因此，对第二容置区域的容积要求较低，即第二容置区域的容积不需要很大，也能够有效地接收冷凝水，非常适合设置在压缩机仓内邻近压缩机的空间较小的区域，因此，本发明的蒸发皿非常适用于双排水系统的冰箱。
本发明的冰箱包括两个冷却室、两个蒸发器、两个排水管、以及一个蒸发皿，可以在不改变压缩机仓内的原有结构布局(例如压缩机、冷凝器、风筒组件、散热风机等)的基础上利用蒸发皿的特殊结构使得两个排水管排出的冷凝水都能够流入该蒸发皿，设计非常巧妙。
进一步地，冰箱的风筒组件将压缩机仓分成左右两部分，蒸发皿的两个容置区域分别位于该左右两部分中，以便于分别接收延伸至该两部分的两个排水管排出的冷凝水，排水管不需要设置成特别复杂的弯曲形状。并且，蒸发皿的连接流道穿设在风筒组件中，确保了风筒组件和蒸发皿仍然沿横向排布，不但不会增加压缩机仓高度方向上的空间，而且对压缩机仓前后方向上的深度要求也不会增加，提高了压缩机仓内各部件的结构布局合理性。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
本发明首先提供一种用于冰箱的蒸发皿，该冰箱具有相互独立设置的第一排水管和第二排水管。也就是说，本发明的蒸发皿适用于具有双排水系统的冰箱。
图1是根据本发明一个实施例的用于冰箱的蒸发皿的示意性结构图，图2是根据本发明一个实施例的用于冰箱的蒸发皿底部的示意性结构图。参见图1和图2，本发明的蒸发皿30包括第一容置区域31、第二容置区域32和连接流道33。第一容置区域31用于接收从冰箱的第一排水管排出的冷凝水，第二容置区域32用于接收从冰箱的第二排水管排出的冷凝水。并且，第二容置区域32在竖向上的高度高于第一容置区域31在竖向上的高度。连接流道33连通第一容置区域31和第二容置区域32，以允许第二容置区域32内的水流入第一容置区域31。第一容置区域31的容量大于第二容置区域32的容量。
冰箱的压缩机在压缩机仓内位于风筒组件的一侧，必然会占用该侧较大的空间，导致该侧剩余空间较小，不便于设置蒸发皿。正因为如此，现有技术中的蒸发皿通常设置在远离压缩机的一侧。然而，本发明的蒸发皿30特别地设有两个容置区域，以分别接收从冰箱的两个排水管中排出的冷凝水。并且，两个容置区域通过连接流道连通，第二容置区域32的高度高于第一容置区域31，由此，第二容置区域32接收到的冷凝水可自动地通过连接流道33流入第一容置区域31，因此，对第二容置区域32的容积要求较低，即第二容置区域32的容积不需要很大，也能够有效地接收冷凝水，非常适合设置在压缩机仓内邻近压缩机的空间较小的区域，因此，本发明的蒸发皿30非常适用于具有双排水系统的冰箱，解决了现有这类冰箱通常所具有的关于冷凝水排放的棘手问题。
具体地，第二容置区域32在竖向上的高度高于第一容置区域31在竖向上的高度具体可以为第二容置区域32的底壁所处的高度高于第一容置区域31的底壁所处的高度，以确保第二容置区域32内的冷凝水具有朝向第一容置区域31流动的趋势。
可选地，第一容置区域31的顶部开口与第二容置区域32的顶部开口在竖直方向上相平齐。此时，第一容置区域31的深度大于第二容置区域32的深度，因此，在相同横截面面积的情况下，第一容置区域31的容量更大，便于容纳更多的冷凝水。
由于压缩机的存在，压缩机仓的被风筒组件隔开的两个部分的剩余空间必然不同。设有压缩机的那部分剩余空间较小，远离压缩机的那部分剩余空间较大。为此，在一些实施例中，第一容置区域31位于风筒组件的远离压缩机的一侧，第二容置区域32和压缩机处于筒体组 件的同一侧，第一容置区域31的横截面面积大于第二容置区域32的横截面面积，以在不产生结构干涉的基础上尽可能地充分利用压缩机仓内的剩余空间布置容量更大的蒸发皿30，从而提高了蒸发皿30接收冷凝水的能力。
在一些实施例中，第一容置区域31和第二容置区域32在水平方向上并排设置。第二容置区域32的底壁沿由第二容置区域32向第一容置区域31的方向倾斜向下延伸。也就是说，第二容置区域32的底壁朝向第一容置区域31倾斜向下，有利于第二容置区域32内的冷凝水更加快速地流向第一容置区域31，避免容量较小的第二容置区域32内积存较多的冷凝水。
具体地，第二容置区域32的底壁可沿固定的斜率平直地倾斜向下延伸，也可以沿曲线弯曲地向下延伸。
在一些实施例中，连接流道33在竖向上的高度高于第一容置区域31在竖向上的高度，以在蒸发皿30安装于冰箱的底板后使得连接流道33和第二容置区域32均悬空地位于冰箱底板的上方。需要说明的是，冰箱的底板指的是位于压缩机仓底部的用于支撑蒸发皿30、压缩机、风筒组件等部件的板体。
具体地，连接流道33的底壁高于第一容置区域31的底壁，以使得连接流道33内的冷凝水具有流向第一容置区域31的趋势，从而使得冷凝水汇集在第一容置区域31中。
并且，连接流道33和第二容置区域32均悬空地位于冰箱底板上方，即连接流道33的底壁和冰箱底板之间、以及第二容置区域32的底壁和冰箱底板之间均形成有让位空间，以便于气流通过，避免连接流道33和第二容置区域32遮挡冰箱底板上原有的进出风口等结构。
申请人认识到，悬空设置的连接流道33和第二容置区域32在容纳冷凝水后，承重增加，容易产生变形，甚至在连接流道33与第一容置区域31之间的连接处、以及第一容置区域31和第二容置区域32之间的连接处容易产生断裂。为此，在一些实施例中，连接流道33和/或第二容置区域32的底部外侧设有向下凸出的支撑座34，支撑座34用于在蒸发皿30安装于冰箱的底板后支撑在该底板上。支撑座34能够为悬空的连接流道33和第二容置区域32提供稳定的支撑，提高了蒸发皿30的结构稳定性，延长了其使用寿命。
进一步地，连接流道33的底部外侧还设有加强筋，加强筋可沿连接流道33的长度方向延伸，以进一步增强连接流道33的结构强度。
在一些实施例中，第二容置区域32的内底壁设有多个向上凸出的支撑筋321，以使得第二排水管的末端抵接于支撑筋321，并在第二排水管的末端与第二容置区域32的内底壁之间形成间隙，以确保第二排水管内的冷凝水能够从该间隙流入第二容置区域32，避免第二排水管的末端直接抵接于第二容置区域32的内底壁造成第二排水管末端堵塞。
在一些实施例中，蒸发皿30还包括挡水筋35，挡水筋35设置于连接流道33的内底壁，或设置于第二容置区域32与连接流道33的连接口处的内底壁。当挡水筋35的朝向第二容置区域32一侧的水面高度低于挡水筋35高度时，冷凝水不会通过挡水筋35，而是保留在第二容置区域32内。由此，可以在第二容置区域32内形成一定高度的水面，便于在第二排 水管的末端形成水封。
进一步地，挡水筋35在竖向上的高度高于支撑筋321在竖向上的高度。由此，可确保第二容置区域32内的水面高度始终高于支撑筋321的高度，即高于第二排水管末端的高度，从而确保了第二排水管的末端始终处于水面以下，既不影响冷凝水的正常排出，又可避免温度较高的外部空气经第二排水管进入冰箱内部，有利于冰箱节省能耗。
在一些实施例中，第一容置区域31、第二容置区域32和连接流道33一体成型。
在另一些实施例中，第一容置区域31、第二容置区域32和连接流道33也可以通过焊接、套接、卡接等合适的方式连接在一起。
本发明还提供一种冰箱，图3是根据本发明一个实施例的冰箱的示意性结构图，图4是沿图3中的剖切线A-A截取的示意性剖视图，图5是沿图3中的剖切线B-B截取的示意性剖视图，图6是根据本发明一个实施例的冰箱部分结构示意性分解图。参见图3至图6，本发明的冰箱1包括箱体10、第一蒸发器21、第二蒸发器22、第一排水管41和第二排水管42。
箱体10的底部限定有压缩机仓13、以及相互独立的第一冷却室112和第二冷却室122。第一蒸发器21和第二蒸发器22分别设置于第一冷却室112和第二冷却室122内。第一排水管41和第二排水管42分别由第一冷却室112和第二冷却室122延伸至压缩机仓13。也就是说，本发明的冰箱具有双排水系统，以分别排出第一冷却室112和第二冷却室122内的冷凝水。
特别地，本发明的冰箱1还包括上述任一实施例所描述的蒸发皿30，蒸发皿30设置于压缩机仓13内，以通过其第一容置区域31接收从第一排水管41排出的冷凝水、通过其第二容置区域32接收从第二排水管42排出的冷凝水。
本发明的冰箱1包括两个冷却室、两个蒸发器、两个排水管、以及一个蒸发皿，可以在不改变压缩机仓13内的原有结构布局(例如压缩机、冷凝器、风筒组件、散热风机等之间的布局)的基础上利用蒸发皿30的特殊结构使得两个排水管排出的冷凝水都能够流入该蒸发皿30，设计非常巧妙。
在一些实施例中，冰箱1还包括压缩机51、散热风机52和风筒组件60。压缩机51和散热风机52设置于压缩机仓13内。风筒组件60用于安装散热风机52，风筒组件60沿箱体10的进深方向(即前后方向)延伸，以将压缩机仓13内的空间分隔成横向并排的两部分。也就是说，压缩机仓13内的空间被风筒组件60分隔成左右两个子空间。
图7是根据本发明一个实施例的蒸发皿、风筒组件和冰箱底板的示意性装配图。进一步地，蒸发皿30的第一容置区域31和第二容置区域32分别位于风筒组件60的横向两侧，压缩机51和第二容置区域32位于风筒组件60在横向上的同一侧。也就是说，压缩机51和第二容置区域32位于压缩机仓13的同一个子空间内，第一容置区域31位于压缩机仓13的另一个子空间内。
由于压缩机51的原因导致第二容置区域32的布置空间有限，因此，第二容置区域32的容量有限。为此，本发明将第二容置区域32在竖向上的高度设置成高于第一容置区域31在竖向上的高度，使得第二容置区域32内的冷凝水能够及时地通过连接流道33汇入第一容置区域31，解决了第二容置区域32的容量小带来的一些列问题。第一容置区域31所在的压缩机仓13的子空间的空间较大，因此可以将第一容置区域31的容量设置得尽可能地大，有利于储存其自身接收的来自第一排水管41的冷凝水和从第二容置区域32流入的来自第二排水管42的冷凝水。
本发明的风筒组件60将压缩机仓13分成左右两部分，蒸发皿30的两个容置区域分别位于该左右两部分中，以便于分别接收延伸至该两部分的两个排水管排出的冷凝水，任一个排水管都不需要设置成特别复杂的弯曲形状，降低了排水管的设计难度和装配难度。
图8是根据本发明一个实施例的风筒组件的示意性结构图。在一些实施例中，风筒组件60包括位于后侧的风机安装部61和连接在风机安装部61前侧的密封隔板62。散热风机52安装在风机安装部61中。密封隔板62上开设有避让缺口621，蒸发皿30的连接流道33穿设在避让缺口621中。
蒸发皿30的连接流道33穿设在风筒组件60的密封隔板62中，既不影响散热风机52的正常安装，又确保了风筒组件60和蒸发皿30仍然沿横向排布，不但不会增加压缩机仓13高度方向上的空间，而且对压缩机仓13前后方向上的深度要求也不会增加，提高了压缩机仓13内各部件的结构布局合理性。
可以理解的是，为了避免占用过多空间，用于连通第一容置区域31和第二容置区域32的连接流道33优选为细长形的流道，只需要在密封隔板62上开设与连接流道33的横截面尺寸大致相当的避让缺口621即可。并且，避让缺口621的底部敞开，以供连接流道33从下往上地装配至避让缺口621中。
在一些实施例中，连接流道33和第二容置区域32均悬空地设置于箱体10的底板14上方，以避免连接流道33和第二容置区域32遮挡冰箱底板14上原有的进出风口等结构。
进一步地，连接流道33的底部外侧设有向下凸出的支撑座34，支撑座34支撑在底板14上，以为悬空的连接流道33和第二容置区域32提供稳定的支撑，提高了蒸发皿30的结构稳定性，延长了其使用寿命。
在散热风机52启动时，压缩机仓13内产生气流流动，以对压缩机51、冷凝器等部件进行散热。申请人认识到，为了提高散热效果，压缩机仓13内的气流优选沿预设路径定向流动，比如，外部空气经进风口进入压缩机51所在的一侧，并由压缩机51所在的一侧通过散热风机52流向第一容置区域31所在的一侧，最后通过出风口返回外部空间；或者外部空气经进风口进入第一容置区域31所在的一侧，并由第一容置区域31所在的一侧通过散热风机52流向压缩机51所在的一侧，最后通过出风口返回外部空间。气流的流动方向取决于散热风机52的具体设置。
为了安装蒸发皿30，本发明在风筒组件60的密封隔板62上开设了避让缺口621，然而，由于连接流道33悬空设置，因此，不可避免地会在避让缺口621的底部形成位于连接流道33下方的空隙。在散热风机52运行时，风筒组件60两侧的空间形成一定的压力差，在该压力差作用下，会有部分气流通过该空隙产生回流，导致热空气再次进入压缩机51所在的空间，降低了压缩机51的散热效率。
为此，本发明将支撑座34设置成封堵避让缺口621位于连接流道33下方的过流面，即封堵避让缺口621的底部形成的位于连接流道33下方的空隙。由此，支撑座34不但能够支撑连接流道33和第二容置区域32，而且还可以阻止热空气通过该间隙回流，确保了压缩机仓13内较好的散热效果。
具体地，支撑座34可设置在连接流道33的位于避让缺口621处的下方，通过对支撑座34的位置进行合理的选择可以起到多方面的有益效果，设计非常巧妙。
图9是根据本发明另一个实施例的蒸发皿的示意性结构图。在一些实施例中，连接流道33内部设有位于避让缺口621处的挡水筋35。也就是说，与前述实施例不同的是，在图9所示实施例中，挡水筋35优选设置在连接流道33内，并位于避让缺口621处。
进一步地，挡水筋35分别由连接流道33的三个内壁垂直向连接流道33的径向内侧延伸，以在挡水筋35的内侧形成流水孔36，流水孔36的过流面积小于连接流道33除流水孔36之外的其他区段的过流面积。需要说明的是，这里的“内”指的是连接流道33的径向内侧。
也就是说，本发明进一步实施例的挡水筋35不但包括由连接流道33的内底壁向上延伸的底部区段，而且还包括由连接流道33的两个侧壁相向延伸的侧部区段。由此，挡水筋35不但可以起到挡水的作用，而且还可以减小连接流道33在挡水筋35处的过流面积，既允许冷凝水流过，又可起到阻止部分空间回流的作用。
在一些实施例中，参见图1，蒸发皿30还包括连接垫板37，连接垫板37的其中一个边缘与第一容置区域31的其中一个边缘相连，连接垫板37的另一个边缘与连接流道33的一侧相连，连接垫板37的又一个边缘与第二容置区域32的其中一个边缘相连，以通过连接垫板37支撑连接流道33和第二容置区域32。具体地，连接垫板37将悬空设置的连接流道33和第二容置区域32的部分边缘与设置在冰箱底板14上的第一容置区域31的部分边缘相连，对连接流道33和第二容置区域32起到了一定的支撑作用，避免连接流道33和第二容置区域32产生变形或断裂，进一步提高了蒸发皿30的结构强度。
进一步地，连接垫板37支撑在箱体10的底板14上，风筒组件60位于连接垫板37上，且连接垫板37上开设有通孔371，以允许风筒组件60的用于与底板14相连的连接部63穿过其中并与底板14相连。连接垫板37的设置不会影响风筒组件60的正常装配。
进一步地，蒸发皿30可通过设置在第一容置区域31底部的连接部和/或设置在连接垫板37底部的连接部与冰箱底板14相连。
在一些实施例中，第一冷却室112和第二冷却室122在箱体10的横向上并排且间隔设置。箱体10内还限定有在箱体10的横向上并排且间隔设置的第一储物间室111和第二储物间室121，第一储物间室111和第二储物间室121分别相邻地位于第一冷却室112和第二冷却室122的上方。第一蒸发器21和第二蒸发器22配置成分别为第一储物间室111和第二储物间室121提供冷量。
也就是说，本发明的冰箱1包括两个相互独立的底置冷却室和两个相互独立的底置蒸发器。将蒸发器底置，不占用储物间室的后侧空间，可以增加储物间室的有效容积。
在一些实施例中，第一储物间室111和第二储物间室121的后侧分别设有第一风道组件71和第二风道组件72，第一风道组件71和第二风道组件72的内部分别限定有第一送风风道和第二送风风道。第一送风风道内设有第一送风风机，且第一送风风道连通第一储物间室111和第一冷却室112，以通过第一送风风机促使第一冷却室112内产生的冷却气流流向第一储物间室111。第二送风风道内设有第二送风风机，且第二送风风道连通第二储物间室121和第二冷却室122，以通过第二送风风机促使第二冷却室122内产生的冷却气流流向第二储物间室121。
在一些实施例中，第一储物间室111和第一冷却室112通过第一盖板151隔开，第二储物间室121和第二冷却室122通过第二盖板152隔开。冰箱1还包括设置于第一盖板151前侧的第一回风罩161和设置于第二盖板152前侧的第二回风罩162。第一回风罩161上开设有用于供第一储物间室111的回风气流流向第一冷却室112的第一回风口1611，第二回风罩162上开设有用于供第二储物间室121的回风气流流向第二冷却室122的第二回风口1621。
在一些实施例中，第一储物间室111和第二储物间室121可以分别为冷冻间室和变温间室。具体地，第一储物间室111的温度通常处于-24℃～-14℃之间，第二储物间室111的温度可随意调节至-24℃～8℃之间。
在一些实施例中，冰箱1的箱体10内还限定有位于第一储物间室111和第二储物间室121上方的第三储物间室171、以及位于第三储物间室171后侧的第三冷却室172，第三冷却室172内设有第三蒸发器23，以通过第三蒸发器23为第三储物间室171提供冷量。
具体地，第三储物间室171可以为冷藏间室，其内的温度通常为2℃～10℃。
以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围。
