本发明涉及家电技术领域，特别是涉及一种蒸发器设置于箱体底部的冰箱。
背景技术
现有底置蒸发器冰箱的排水口位于蒸发器的下部，排水斜面前部与蒸发器的前部接触，在利用倾斜面排水的同时起到支撑蒸发器的作用，排水管与箱体的出管面多为互相垂直。但是，由于蒸发器到排水口高度差较大，此处空间无法利用，从而浪费了冰箱的容积。而且，部分回风会进入到排水面与蒸发器之间的空间，再通过蒸发器前部与排水斜面被吸入风机进口风，换热路径减少，降低了蒸发器的利用率。
发明内容
本发明的一个目的是要提供一种克服上述问题或者至少部分地解决上述问题的蒸发器设置于箱体底部的冰箱。
本发明一个进一步的目的是要提高冰箱的空间利用率，提高蒸发器的换热效率。
本发明另一个进一步的目的是要降低外界热空气从排水管进入冰箱内部的比例，从而减少储物空间内的温升。
本发明另一个进一步的目的是提高排水管的密封效果以及安装稳固性。
特别地，本发明提供了一种蒸发器设置于箱体底部的冰箱，包括：箱体，具有底部内胆，底部内胆限定有冷却室和储物空间，冷却室设置于储物空间的下方；蒸发器，安装于冷却室内；其中底部内胆的底壁包括：第一支撑部，从底壁的前端从前至后向下倾斜设置；下凹部，设置于第一支撑部的后侧，并配置成从横向中部向两侧向上倾斜，从而在横向中部开设排水口，排水口用于排出冷却室内的水；第二支撑部，从排水口的后端从前至后向上倾斜设置，并且蒸发器放置于第二支撑部上，并且蒸发器的前端与第一支撑部抵触，从而使得其上出现的水汇聚于下凹部。
进一步地，第二支撑部的倾斜角度大于或等于4°。
进一步地，蒸发器与第二支撑部的贴合部分占蒸发器底面的比例大于或 等于0.6。
进一步地，蒸发器至下凹部的最底端的距离小于或等于50mm。

进一步地，排水管的倾斜角度大于等于5°且小于等于10°。
进一步地，蒸发器设置于箱体底部的冰箱，还包括：压机舱盖板，作为压机舱的顶面，并与底部内胆的底壁间隔设置，压机舱盖板上开设有供排水管穿过的管孔，并且排水管在穿过压机舱盖板的区段上套接有套管和固定环，排水管位于压机舱盖板上部的位置设置有凸缘，位于压机舱盖板下部的位置设置有外螺纹，所述固定环通过与外螺纹配合将凸缘与压机舱盖板进行固定。
进一步地，底部内胆的底壁还包括：第三支撑部，从第二支撑部的后部从前至后向上倾斜设置，其倾斜角度大于第二支撑部的倾斜角度；并且冰箱还包括：风道背板，设置于底部内胆的后壁的前方，并与底部内胆的后壁限定出送风风道，并且风道背板开设有至少一个送风口，送风口用于连通送风风道以及储物空间，制冷风机，设置于第三支撑部上，其排风口与送风风道的下端相连，并配置成促使形成经由蒸发器送向送风风道的制冷气流。
进一步地，蒸发器的底部还设置有加热丝，用于化除蒸发器上的结霜；并且蒸发器与下凹部相对的区域上设置的加热丝的密度大于蒸发器与第二支撑部相对的区域上设置的加热丝的密度。
进一步地，蒸发器设置于箱体底部的冰箱，还包括：分隔盖板，横向设置于底部内胆内，用于将底部内胆的内部空间分隔为冷却室和储物空间；以及回风罩，设置于冷却室的前部，其上开设有连通冷却室和储物空间的至少一个前回风口，利用前回风口向冷却室提供换热所需的空气，并且回风罩的顶部与分隔盖板的前端相连接。
本发明的蒸发器设置于箱体底部的冰箱，由于将蒸发器斜置，降低了蒸发器与排水口之间的距离，从而提高了冰箱的空间利用率，并进一步降低了排水口处的结霜风险。

进一步地，本发明的蒸发器设置于箱体底部的冰箱，通过将排水管倾斜设置，一方面降低了排水管在竖直高度上所占的空间，进一步地提高了冰箱的空间利用率。另一方面，增加了排水管的长度，从而提高了排水管内的空气流动阻力，进而减少了外界热空气进入冰箱内部的比例，并进一步地达到了节能、减少储物空间内温升以及降低风道结霜风险的目的。
进一步地，本发明的蒸发器设置于箱体底部的冰箱，通过在回气管上设置凸缘以及外螺纹，利用套管和固定环与回气管的凸缘以及外螺纹相配合，从而提高了回气管的安装稳固性。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是根据本发明一个实施例的冰箱的示意性主视图；
图2是根据本发明一个实施例的冰箱的示意性剖视图；
图3是图2中区域A的示意性放大图；
图4是根据本发明一个实施例的冰箱的底部内胆的剖面俯视图，其示出了底部内胆的底部上表面。
具体实施方式
在本实施例的描述中，需要理解的是，术语“横向”、“长度”、“上”、“下”、“前”、“后”、“竖直”、“水平”、“顶”、“底”等指示的方位或位置关系为基于冰箱10正常使用状态下的方位作为参考，并参考附图所示的方位或位置关系可以确定，例如指示方位的“前”指的是冰箱10朝向用户的一侧。这仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
参考图1-4，本实施例首先提供了一种冰箱10，该冰箱10的蒸发器160布置于箱体100底部，冰箱10一般性地包括箱体100，箱体100具有底部内胆110，底部内胆110限定有储物空间130以及位于储物空间130下方的冷却室120，冷却室120通过开设于其前部的回风口与储物空间130连通。该底部内胆110指位于冰箱10最下方的内胆。
一般性地，冰箱10可以有多个内胆，根据其功能可以划分为冷冻内胆、变温内胆、以及冷藏内胆，从而限定出多个储藏间室：例如冷藏间室、变温间室和冷冻间室。
在本实施例中，位于冰箱10底部的底部内胆110限定有储物空间130以及位于储物空间130下方的冷却室120，其中，底部内胆110限定的储物空间130一般可以为冷冻间室。此外，储物空间130上方还可以有冰箱10其它内胆限定出的变温间室，以及位于变温间室上方的冷藏间室。
本实施例的冰箱10还可以包括蒸发器160，其安装于冷却室120内。蒸发器160可由底部内胆110的底壁支撑，用于提供冰箱10的冷量。
底部内胆110的底壁可以包括：第一支撑部170、下凹部171、第二支撑部172。第一支撑部170从底壁的前端从前至后向下倾斜设置。下凹部171设置于第一支撑部170的后侧，并配置成从横向中部向两侧向上倾斜，从而在横向中部开设排水口177，排水口177用于排出所述冷却室120内的水。第二支撑部172，从排水口177的后端从前至后向上倾斜设置，并且蒸发器160放置于第二支撑部172上，并且蒸发器160的前端与第一支撑部170抵触，从而使得其上出现的水汇聚于下凹部171。下凹部171两侧的倾斜角度可以大于等于7度，使得两侧的水向排水口177汇聚。下凹部171的构造还可以使蒸发器160尽量减少与底部内胆110的底壁的间距，从而可以利用蒸发器160的加热丝161热量传递到下凹部，使化霜水有效流进排水口177处。进一步地，上述下凹部171的构造利用蒸发器160的加热丝161热量进行除霜，避免了冰块封堵排水口177，也无需在排水口177处额外增加加热丝。
本实施例的方案通过将蒸发器160设置于第二支撑部172上，并设置蒸发器160的前端与第一支撑部170抵触，也即使得蒸发器160从前至后倾斜向上设置，从而降低了蒸发器160与排水口177之间的距离，不仅提高了冰箱10的空间利用率，而且保障蒸发器160上的加热丝161能够对排水口177处的区域进行加热，从而降低了排水口177处的结霜风险。
进一步地，蒸发器160设置于第二支撑部172上，还可以使得蒸发器160底面与底部内胆110的底壁之间的贴合长度增加，从而避免通过前回风口151进入冷却室120内的空气，通过排水口177与蒸发器160底面之间的空间流入制冷风机180，进而提高了空气流经蒸发器160的路径长度，进一步地提高了蒸发器160的换热效率。
第二支撑部172的倾斜角度可以大于或等于4°，更优选地，可以为设置大于等于7°，例如7.5°。也即使得蒸发器160的倾斜角度大于或等于4°，更优选地大于等于7°，例如7.5，以便于化霜水向排水口177汇集。本实施例的方案通过设置第二支撑部172的倾斜角度大于或等于4°，不仅提高了冷却室120容积的利用率，而且使得位于第二支撑部172上的化霜水可以更加顺畅地流入排水口177，从而保证两侧的水及时流走，降低结霜风险。
在一些实施例中，虽然扁平长方体的蒸发器160倾斜放置会导致前后方向的长度增加，但是将其斜置使得冷却室120内其他部件的布置更加合理，而且经过实际气流流场分析证实风循环效率也更加高，排水也更加舒畅。
蒸发器160与第二支撑部172的贴合部分占蒸发器160底面的比例大于或等于0.6，例如可以设置2/3、3/4等，从而可以使得排水口177位于蒸发器160前部的下方。本实施例的方案通过设置蒸发器160与第二支撑部172的贴合部分占蒸发器160底面的比例大于或等于0.6，从而保障蒸发器160底面与第二支撑部172的贴合长度，进而避免空气不流进蒸发器160而从蒸发器160底面与排水口177之间的空间流过，提高了空气流经蒸发器160的路径长度，进一步地提高了蒸发器160的换热效率。
蒸发器160至下凹部171的最底端的距离L小于或等于50mm，更优选地，可以为设置小于等于25mm。
现有技术中，为了提高底置蒸发器冰箱的容积率和安全，采用铝管加热技术，但是铝管热量比较低，如果蒸发器排水口177估计不到的话可能会造成排水口177冰堵，蒸发器底部结霜的问题。
本实施例的方案通过设置蒸发器160至下凹部171的最低端的距离小于或等于50mm，不仅减小了蒸发器160相对于地面的高度，提高了冰箱10的储物空间130的容积，而且保障蒸发器160上的加热丝161能够对排水口177处的区域进行加热，从而降低了排水口177处的结霜风险。
在一些实施例中，蒸发器160至下凹部171的最底端的距离还可以被设 置为小于或等于25mm，例如，设置可以设置为25mm。在保证排水效果的前提下，将蒸发器160到下凹部171的最底端的高度降到了最低。上述蒸发器160到下凹部171的最底端的高度的设置，是根据排水性能要求和空间要求而进行的结构性优化，并且得到试制产品的效果验证。
箱体100在底部内胆110的下方的后部形成压机舱190，并且冰箱10还可以包括蒸发皿191和排水管192。蒸发皿191设置于压机舱190内；排水管192从排水口177从前向后向下倾斜延伸至蒸发皿191处。
本实施例的方案中，通过在压机舱190的底部设置蒸发皿191并设置排水管192从排水口177从前向后向下倾斜延伸至蒸发皿191处，使得蒸发皿191对从排水管192处流出的化霜水进行收集，而后利用冷凝器(图中未示出)中产生的热量将蒸发皿191中的化霜水蒸发。
排水管192的倾斜角度β可以大于等于5°且小于等于10°。例如，可以设置为7°。本实施例的方案通过将排水管192的倾斜角度设置为大于等于5°且小于等于10°，从而使得排水管192中的化霜水的流动的更加顺畅，同时保证排水管192不会在高度方向上占用过多的空间。上述排水管192的倾斜角度是根据排水性能要求和空间要求而进行的结构性优化，并且得到试制产品的效果验证。
蒸发器160设置于箱体100底部的冰箱10还可以包括压机舱盖板193。压机舱盖板193作为压机舱190的顶面，并与底部内胆110的底壁间隔设置，压机舱盖板193上开设有供排水管192穿过的管孔，并且排水管192在穿过压机舱盖板193的区段上套接有套管196和固定环197，排水管192位于压机舱盖板193上部的位置设置有凸缘194，位于压机舱盖板193下部的位置设置有外螺纹195，固定环197通过与外螺纹195配合将凸缘194与压机舱盖板193进行固定。
参见图3，本实施例的方案通过在排水管192上设置有凸缘194，使得凸缘194与压机舱盖板193上部的位置相接触，从而保障压机舱盖板193不会沿着排水管192的向斜上方移动。进一步地，本实施例的方案通过在排水管192上设置有外螺纹195，并设置固定环197与外螺纹195进行螺纹连接，从而确保压机舱盖板193无法沿着排水管192向斜下方移动。
进一步地，本实施例的冰箱还设置有套管196，套管196安装于排气管上与压机舱盖板193的下表面接触，其远离压机舱盖板193的一端所在的端 面垂直于排气管的轴线。上述的套管196的结构设置使得固定环197可以通过压紧套管196均匀地在压机舱盖板193上施加作用力，避免了由于排水管192与压机舱盖板193不垂直从而导致固定环197与对压机舱盖板193部分接触，从而导致压机舱盖板193受力不均，压紧困难。
本实施例的方案通过设置套管196、固定环197以及在位于排水管192上的凸缘194和外螺纹195，对排气管相对于压机舱盖板193的位置进行限定，从而提高倾斜设置的排水管192的安装稳固性。
在一些实施例中，凸缘194相对于压机舱盖板193的一侧还可以设置有密封垫198，通过旋接固定环197，使得密封垫198被压紧，从而防止箱体100在进行发泡时发泡材料通过压机舱盖板193上的管孔溢入压机舱190。
底部内胆110的底壁还可以包括第三支撑部173。第三支撑部173从第二支撑部172的后部从前至后向上倾斜设置，其倾斜角度大于第二支撑部172的倾斜角度。并且冰箱10还包括风道背板和制冷风机180。风道背板设置于底部内胆110的后壁的前方，并与底部内胆110的后壁限定出送风风道175，并且风道背板开设有至少一个送风口176，送风口176用于连通送风风道175以及储物空间130。制冷风机180设置于第三支撑部173上，其排风口181与送风风道175的下端相连，并配置成促使形成经由蒸发器160送向送风风道175的制冷气流。
本实施例的方案通过在倾斜地第三支撑部173上设置制冷风机180，将流经蒸发器160的气流加速送入送风风道175，从而提高空气循环效率，进而保障冰箱10的冷冻冷藏功能。制冷风机180倾斜设置，最大限度的节省了蒸发器160与制冷风机180之间的进深距离，既保证了蒸发器160与制冷风机180的距离足够，减少蒸发器160结霜现象的发生，也保证了冰箱10内部结构紧凑，增大空间利用率，将制冷风机180倾斜设置是根据制冷性能要求和空间要求进行的结构性改进。制冷风机180可以采用离心风机，其吸风口朝向斜上方，从而从蒸发器160吸入空气，并利用后部的排风口向送风风道175送风。
进一步地，本实施例的方案中风道盖板174上开设有至少一个送风口176，也就是说，本实施例的方案中风道盖板174可以开有一个或多个送风口176，具体可以根据制冷需求进行设置。
蒸发器160的底部还设置有加热丝161，用于化除蒸发器160上的结霜； 并且蒸发器160与下凹部171相对的区域上设置的加热丝161的密度大于蒸发器160与第二支撑部172相对的区域上设置的加热丝161的密度。
本实施例的方案通过在蒸发器160的底部设置加热丝161，从而对蒸发器160的周围空间进行加热，避免蒸发器160上出现结霜。同时，由于本实施例的方案中对蒸发相对于下凹部171的底端(即排水口177)的距离进行了限制，使得蒸发器160的底部的加热丝161同样能够对排水口177处的区域进行加热，进而降低了排水口177处的结霜风险。进一步地，本实施例的方案通过设置蒸发器160与下凹部171相对的区域上设置的加热丝161的密度大于蒸发器160与第二支撑部172相对的区域上设置的加热丝161的密度，使得蒸发器160与下凹部171相对的区域的加热丝161释放的热量更多，从而进一步提高了下凹部171区域的化霜效率。
加热丝161与内胆距离相近，如果加热丝161工作出现故障，加热丝161温度过高可能会造成内胆局部变形。因此，在本发明的一些实施例中，还可以在蒸发器160与内胆连接的位置固定温度熔断器，并控制最长化霜时间不超过一设定时长(例如1h，可以根据实际应用需求进行灵活调整)，如果在该设定时长内温度上升至较高温度点(如77°，可以根据实际应用需求进行灵活调整)时，温度熔断器断开，从而保障冰箱10蒸发器160内部的安全。
蒸发器160设置于箱体100底部的冰箱10还可以包括分隔盖板140和回风罩150。分隔盖板140横向设置于底部内胆110内，用于将底部内胆110的内部空间分隔为冷却室120和储物空间130。回风罩150设置于冷却室120的前部，其上开设有连通冷却室120和储物空间130的至少一个前回风口151，利用前回风口151向冷却室120提供换热所需的空气，并且回风罩150的顶部与分隔盖板140的前端相连接。
本实施例的方案通过在底部内胆110上设置分隔盖板140，将底部内胆110的内部空间分隔为冷却室120和储物空间130，从而保证冷却室120与储物空间130互不干扰。在本发明的一些实施例中，分隔盖板140的上表面基本水平设置，最大限度的增加了储物空间130的容积，有利于形成完整的储物空间130，使空间利用率更高。本市实施例的方案中回风罩150上开设有至少一个前回风口151，也就是说，回风罩150上可以设置有一个或多个前回风口151。例如，在一些实施例中，回风罩150上可形成上下分布的两个前回风口151，不但视觉美观，还可有效防止儿童手指或异物进入冷却空 间中；并且，上下分布的两个回风区域可使回风进入冷却空间后更均匀流过蒸发器160，可在一定程度上减少蒸发器160前端面易结霜的问题，不但可提高换热效率，还可延长化霜周期，节能高效。回风罩150的顶部与分隔盖板140的前端上分别设置有相互配合的卡扣连接结构(图中未示出)，以互相卡接，使得分隔盖板140与回风罩150的连接地更加稳固。
本实施例的蒸发器160设置于箱体100底部的冰箱10，通过将蒸发器160斜置，一方面降低了蒸发器160与排水口177之间的距离，从而提高了冰箱10的空间利用率，并进一步降低了排水口177处的结霜风险。另一方面，提高了蒸发器160底面与底部内胆110的底壁之间的贴合长度，从而提高空气流经蒸发器160的长度，进而提高蒸发器160的换热效率。
进一步地，本实施例的蒸发器160设置于箱体100底部的冰箱10，通过将排水管192倾斜设置，一方面降低了排水管192在竖直高度上所占的空间，进一步地提高了冰箱10的空间利用率。另一方面，增加了排水管192的长度，从而提高了排水管192内的空气流动阻力，进而减少了外界热空气进入冰箱10内部的比例，并进一步地达到了节能、减少储物空间130内温升以及降低风道结霜风险的目的。
进一步地，本实施例的蒸发器160设置于箱体100底部的冰箱10，通过在回气管上设置凸缘194以及外螺纹195，利用套管196和固定环197与回气管的凸缘194以及外螺纹195相配合，从而提高了回气管的安装稳固性。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
